                                    SUMMARY

  This summary may not contain all the information that is important to you.
You should read the entire prospectus, including the consolidated financial
statements and related notes, before deciding to invest in shares of our common
stock.

  Unless otherwise indicated, all information in this prospectus assumes the
underwriters do not exercise their over-allotment option and reflects the
conversion of all of our outstanding preferred stock into common stock, which
will take effect immediately before the closing of this offering.

                                    NetSolve

  We offer a range of services that allow companies to selectively outsource,
or "out-task," activities relating to the design, implementation, management
and security of their computer networks. Our network management and security
services are designed to increase network reliability and up-time, reduce
overall network costs, and simplify timely migration to new technologies.

  Businesses increasingly depend on the ability to access and share electronic
information reliably. As a result, networks have become a more critical part of
day-to-day operations and businesses are seeking ways to implement responsive,
reliable and secure networks. Many companies are large enough to employ large
computer networks across multiple sites, referred to as wide area networks, or
WANs, but may be too small to afford or may prefer not to devote the
information technology personnel necessary to manage and secure their networks.
Facing rapid advances in technology and a continuing shortage of information
technology professionals, these companies are beginning to turn to third-party
service providers for network management and security solutions.

  Our network management services address all or selected parts of the full
life cycle of network management, which consists of the following elements:

  . implementation                   . fault resolution                 . documentation
</TABLE>

  We furnish our network management services remotely 24 hours per day, seven
days per week from our network management center in Austin, Texas, and we offer
software tools that allow companies to access up-to-date network status reports
through standard Web browsers. We also provide around-the-clock remote security
services for networks' Internet and intranet perimeter points.

  We target middle market companies, roughly defined as companies that have
between 200 and 1,500 employees and annual revenues between $50 million and
$2.5 billion. More than 575 middle market companies currently use our services
to manage approximately 8,700 network sites. We market our services through
relationships with resellers, including telecommunications carriers, Internet
service providers and value-added resellers, as well as through our direct
sales force. Sales to AT&T, which resells our services to its customers,
accounted for 59% of our total revenues in our fiscal year ended March 31, 1999
and 69% of our total revenues in the three months ended June 30, 1999. We
derive our revenues from both recurring and non-recurring network management
services, as well as from equipment resales.

  Our executive offices are located at 12331 Riata Trace Parkway, Austin, Texas
78727. Our telephone number is (512) 340-3000, and our web site is located at

                                  RISK FACTORS

  Investing in shares of our common stock involves risks. You should be able to
bear a complete loss of your investment. You should carefully consider the
following factors and other information in this prospectus before deciding to
invest in shares of our common stock.

We may be unable to operate profitably in the future.

  We may not operate profitably. Although we began operating in 1987, we did
not introduce our first network management service until the quarter ended
March 31, 1994. Our track record of operating profitably in the network
management services business is short, and it is difficult to predict our
future revenues and operating results. We have previously incurred substantial
net losses. Our ability to operate profitably in the future depends on
increasing sales of our services while maintaining sufficient gross profit
margins. We must, among other things:

  .  maintain satisfactory relationships with resellers such as AT&T, our
     largest customer, and network equipment manufacturers such as Cisco;

  .  establish relationships with additional marketing partners for the
     resale of our services;

  .  develop software to make our principal existing service, ProWatch for
     WANs, more efficient and economical;

  .  develop and sell other network management services; and

  .  maintain reliable, uninterrupted service from our network management
     center 24 hours per day, seven days per week.



We depend on AT&T for a large portion of our sales.

  Sales to AT&T, which resells our services to its customers, accounted for 59%
of our total revenues in the fiscal year ended March 31, 1999 and 69% of our
total revenues in the three months ended June 30, 1999. We expect sales to AT&T
to continue to comprise a substantial percentage of our revenues at least
through fiscal year 2000 and it is possible this percentage could increase. We
cannot be sure that we will be successful in reducing our dependence on AT&T in
the future.

  Our existing agreements with AT&T expire at various dates beginning in
December 1999. In addition, a number of the orders for services that we provide
to AT&T's customers under an agreement expiring in December 2001 can be
cancelled beginning in July 2000 and all new orders placed after June 30, 1999
can be cancelled beginning July 2001. Our agreements with AT&T are not
exclusive arrangements. We will need to maintain a good working relationship
with different business units of AT&T in order to maintain the business we
currently provide to AT&T's customers and to encourage AT&T to sell our
services to additional customers. Problems in our relationship with AT&T would
seriously damage our business. We cannot assure you that AT&T will continue to
sell our services to existing or additional AT&T customers. A substantial
reduction in our AT&T business would result in diminished revenues for an
extended period of time as we attempt to replace that business.

  On December 9, 1998, AT&T announced that it was acquiring IBM's Global
Network business, which services the networking needs of global companies, mid-
sized businesses and individual Internet users. We are unable to predict what
impact, if any, this acquisition will have on our relationship with AT&T.

Our quarterly results may fluctuate and cause the price of our common stock to
fall.

  Our revenues and results of operations are difficult to predict and may
fluctuate significantly from quarter to quarter. If either our revenues or
results of operations fall below the expectations of investors or public market
analysts, the price of our common stock could fall dramatically.

  Our revenues are difficult to forecast and may fluctuate for a number of
reasons:

  .  the market for network management services is relatively new, and we
     have no reliable means to assess overall customer demand;

                                       6
<PAGE>

  .  we derive a majority of our revenues from AT&T and other resellers, and
     our revenues therefore depend significantly on the willingness and
     ability of AT&T and those other resellers to sell our services to their
     customers;

  .  we may not be able to attract additional resellers to market our
     services as expected;

  .  we expect to encourage end users to purchase equipment from other
     sources, and we therefore anticipate that our revenues from equipment
     resales will decline as we seek to manage our mix of revenues;

  .  we may not add new end users as rapidly as we expect;

  .  we may lose existing end users as the result of competition, problems
     with our services or, in the case of end users who are customers of our
     resellers, problems with the reseller's services; and

  .  we may not be able to develop new or improved services as rapidly as
     they are needed.

  Most of our expenses, particularly employee compensation and rent, are
relatively fixed. As a result, variations in the timing of revenues could
significantly affect our results of operations from quarter to quarter and
could result in quarterly losses.

Our future operating results may vary by season, which will make it difficult
to predict our future performance.

  Our bookings may be slower during the months of July and August due to the
vacation schedules of our resellers' sales and marketing employees. This
situation may lead to lower levels of revenues earned during the following
fiscal quarter, which ends December 31.

  Our revenues during our third and fourth fiscal quarters may be more volatile
and difficult to predict due to the budgeting and purchasing cycles of our end
users. End users typically purchase our services at the same time they purchase
new network equipment such as routers. As a result, the timing of their large
capital expenditures could affect the timing of their purchases of our
services. Some end users may not be able to purchase network equipment and our
services near the end of a calendar year due to depleted budgets. Other end
users may accelerate purchases in order to use an unspent portion of their
budget.

  As a result of these factors, we believe that quarter-to-quarter comparisons
of our results of operations are not necessarily meaningful. You should not
rely on our quarterly results of operations to predict our future performance.

The market for our services is new and evolving rapidly, and our business could
be seriously damaged if the market does not develop as we expect.

  Our long-term viability depends significantly upon the acceptance and use of
remote network management services by mid-sized companies. The market for
remote network management services is new and rapidly evolving. This market
environment makes it more difficult to determine the size and growth of the
market and to predict how this market will develop. Changes in technology, the
availability of qualified information technology professionals and other
factors that make internal network management more cost effective than remote
network management would adversely affect the market for our services. Our
business may be seriously damaged if this market fails to grow, grows more
slowly than we expect or develops in some way that is different from our
expectations.

We must establish relationships with additional resellers in order to broaden
the marketing and sales of our services.

  We expect to rely increasingly on resellers such as telecommunications
carriers, Internet service providers and data networking value-added resellers
to market our services. We must establish these alternative sales channels in
order to increase our revenues and become consistently profitable. We have
limited experience in managing sales through resellers. We have only recently
begun to develop these sales channels, and we have

                                       7
<PAGE>


established relationships with only a few resellers. Except for AT&T, these
resellers have not generated significant sales of our services to date and may
not succeed in marketing our services in the future.

  Our agreements with resellers, including AT&T, generally do not require that
the resellers sell any minimum level of our services and generally do not
restrict the resellers' development or sale of competitive services. We cannot
be sure that these resellers will dedicate resources or give priority to
selling our services. In addition, resellers may seek to make us reduce the
prices for our services in order to lower the total price of their equipment,
software or service offerings.

  If we succeed in increasing our sales through resellers, we may have weaker
relationships with the end users of our services. This may inhibit our ability
to gather customer feedback that helps us improve our services, develop new
services and monitor customer satisfaction. We may also lose brand
identification and brand loyalty, since our services may be identified by
private label names or may be marketed differently by our resellers. A failure
by any of our resellers to provide their customers with satisfactory products,
services or customer support could injure our reputation and seriously damage
our business. Our agreements with these resellers may limit our ability to sell
our services directly to the resellers' customers in the future.

We depend on one service for most of our revenues.

  Sales of our ProWatch for WANs and similar wide area network, or WAN,
management services accounted for 98% of our recurring network management
services revenues in the fiscal year ended March 31, 1999. Likewise, a
substantial portion of our nonrecurring network management services and
equipment resale revenues depend on the successful sale of these WAN management
services. We expect that these WAN management services will continue to
generate substantially all of our revenues for the foreseeable future. Our
success therefore depends directly on continued market acceptance of our WAN
management services, as well as our ability to introduce enhanced versions of
these services that make these services more efficient and economical.
Competitive pressures or other factors that adversely affect sales of our WAN
management services or that cause significant decreases in the prices of our
WAN management services could significantly limit or reduce our revenues.

  Our future financial performance will depend in part on our ability to
develop, introduce and sell new and enhanced network management services other
than WAN management services, including services that:

  .  address the increasingly sophisticated needs of current and prospective
     end users; and

  .  respond on a timely and cost-effective basis to technological advances
     and emerging industry standards and protocols.

  Although we have developed new services, such as network management services
for local area networks, or LANs, and network security services, we have not
derived significant revenues from these services to date. We cannot be sure
that we will be successful selling these services or developing additional
services on time or on budget. The development of new services is a complex and
uncertain process. The newness of the market for remote network management
services makes it difficult to determine whether a market will develop for any
particular network management service. If we succeed in increasing the
percentage of our revenues that is derived from resellers, we may have weaker
relationships with the end users of our services, making it even more difficult
for us to identify services acceptable to our target market of mid-sized
companies. We cannot assure you that future technological or industry
developments will be compatible with our business strategy or that we will be
successful in responding to such changes in a timely or cost-effective manner.
Our failure to develop and sell services other than WAN management services
could seriously damage our business.

Our business may be harmed if we lose the services of our chief executive
officer.

  Our future success depends to a significant degree on the skills, experience
and efforts of our executive officers, particularly Craig S. Tysdal, our
president and chief executive officer. Mr. Tysdal has led us during

                                       8
<PAGE>


our transition from our data transport business to the network management
services field. He is our key representative in our relationship with AT&T. We
do not have employment contracts requiring Mr. Tysdal or any of our other
personnel to continue their employment for any period of time, and we do not
maintain key man life insurance on Mr. Tysdal or any of our other personnel.
The loss of the services of Mr. Tysdal would seriously damage our business.

We face intense competition for qualified information technology professionals.

  We derive all of our revenues from network management services and related
resales of equipment. These services can be extremely complex, and in general
only highly qualified, highly trained information technology, or IT,
professionals have the skills necessary to develop and provide these services.
In order to continue to support our current and future business, we need to
attract, motivate and retain a significant number of qualified IT
professionals. Qualified IT professionals are in short supply, and we face
significant competition for these professionals, from not only our competitors
but also our end users, marketing partners and other companies throughout the
network services industry. Other employers may offer IT professionals
significantly greater compensation and benefits or more attractive career paths
or geographic locations than we are able to offer. Any failure on our part to
hire, train and retain a sufficient number of qualified IT professionals would
seriously damage our business.

  Because of the limited availability of IT professionals, we seek to hire
persons who have obtained college bachelor's degrees and then train those
persons to provide our services. As a result, we invest a significant amount of
time and money in training these new employees before they begin to support our
business. We do not enter into employment agreements requiring these employees
to continue in our employment for any period of time. Departures of trained
employees could limit our ability to generate revenues and would require us to
incur additional costs in training new employees.

We currently compete most directly with our customers' internal solutions, and
we expect increasing competition from other network services companies.

  We face competition from different sources. Currently, we compete principally
with potential end users' and resellers' internal network administration
organizations. These organizations may have developed tools and methodologies
to manage their network processes and may be reluctant to adopt applications
offered by third parties like us.

  If the market for out-sourced network management services grows as we expect,
we believe this market will become highly competitive. Competition is likely to
increase significantly as new network management services companies enter the
market and current competitors expand their service and product lines. Many of
these potential competitors are likely to enjoy substantial competitive
advantages, including:

  .  larger technical staffs;

  .  more established sales channels;

  .  more software development experience;

  .  greater name recognition; and

  .  substantially greater financial, marketing, technical and other
     resources.

  To be competitive, we must respond promptly and effectively to the challenges
of technological change, evolving standards and our competitors' innovations by
continuing to enhance our services, as well as our sales programs and channels.
Any pricing pressures, reduced margins or loss of market share resulting from
increased competition, or our failure to compete effectively, could seriously
damage our business.

If our operations are interrupted, we may lose customers and revenues.

  To succeed, we must be able to operate our network management infrastructure
24 hours per day, seven days per week without interruption. All of our network
management services are provided remotely from our network management center,
which is located at a single site in Austin, Texas. We do not have any
redundant

                                       9
<PAGE>


systems or facilities at a separate geographic location. In order to operate
without interruption, we must guard against:

  .  power outages, fires, tornados and other natural disasters at our
     network management center;

  .  telecommunications failures;

  .  equipment failures or "crashes;"

  .  security breaches; and

  .  other potential interruptions.

  Any interruptions could:

  .  require us to make payments on the contractual performance guarantees we
     offer our customers;

  .  cause end users to seek damages for losses incurred;

  .  require us to spend more money replacing existing equipment or adding
     redundant facilities;

  .  damage our reputation for reliable service;

  .  cause existing end users and resellers to cancel our contracts; or

  .  make it more difficult for us to attract new end users and resellers.

  Any of these results could seriously damage our business.

The networking equipment and carrier services we support may become obsolete.

  As part of our strategy, we have elected to support only selected providers
of networking equipment and carrier services. For example, we support routers
manufactured by 3Com, Bay/Nortel, Cabletron and Cisco, but not by other
equipment providers. Our services cannot be used by companies with networking
equipment and carrier services that we do not support. Our business would be
seriously damaged if the networking equipment and carrier services that we
support are not used by a significant portion of our target market or if they
become unavailable or significantly more expensive. Technological advances that
make obsolete any of the networking equipment and carrier services that we
support, or that offer significant economic or functional advantages over such
equipment and services, also could limit or reduce our revenues or could force
us to incur significant costs attempting to support other networking equipment
and carrier services.

We may be unable to protect our intellectual property, and we could incur
substantial costs defending our intellectual property from infringement or
claims of infringement made by others.

  Our success depends to a significant degree upon our software and other
proprietary technology. The software industry has experienced widespread
unauthorized reproduction of software products. We have no patents. The steps
we have taken may not be adequate to deter competitors from misappropriating
our proprietary information, and we may not be able to detect unauthorized use
and take appropriate steps to enforce our intellectual property rights.

  We could be the subject of claims alleging infringement of third-party
intellectual property rights. In addition, we may be required to indemnify our
distribution partners and end users for similar claims made against them. Any
such claims could require us to spend significant time and money in litigation,
pay damages, develop non-infringing intellectual property or acquire licenses
to intellectual property that is the subject of the infringement claims. As a
result, any such claim could seriously damage our business.

Our stock price may be volatile.

  Volatility in our stock price may negatively impact the price investors may
receive for their shares of our common stock and increase the risk that we
could be the subject of costly securities litigation. The market price of our
common stock may fluctuate substantially due to a variety of factors,
including:

  .  the reaction of the market to the negotiated public offering price;

  .  quarterly fluctuations in our results of operations;

                                       10
<PAGE>

  .  changes in our relationship with AT&T;

  .  adverse circumstances affecting the introduction or market acceptance of
     new products or services offered by us;

  .  announcements of new products or services by competitors;

  .  changes in our business strategies;

  .  changes in earnings estimates by public market analysts;

  .  inactivity in the trading market for our stock;

  .  loss of market-making or securities analyst coverage for our stock;

  .  changes in accounting principles;

  .  sales of common stock by existing holders; and

  .  loss of key personnel.

We may incur significant costs from securities litigation.

  In the past, securities class action litigation often has been brought
against companies following periods of volatility in the market price of their
stock. We may in the future be the target of similar litigation. Securities
litigation against us could result in substantial costs and divert our
management's attention and resources.

Problems related to the year 2000 issue could cause system failures that impair
our operations.

  Many currently installed computer systems and software products only accept
two digits to identify the year in any date. Thus, the year 2000 will appear as
"00," which the system might consider to be the year 1900 rather than 2000.
This could result in system failures, delays or miscalculations. Computer
systems and software that have not been developed or enhanced recently may need
to be upgraded or replaced to comply with year 2000 requirements.

  We have only recently completed the conversion of our financial and
accounting system to make it year 2000 compliant and we are still in the
process of completing routine upgrades to some of our server and desktop
computer operating systems, desktop computer packaged software, desktop
computer firmware and one third-party software tool. We expect to spend less
than $100,000 to complete all remaining hardware and software upgrades in order
to be year 2000 compliant. If, however, we discover significant year 2000
errors or defects, we could incur substantial costs and our operations could be
seriously disrupted.

We could be subject to significant liability claims.

  Because our products are designed to provide critical network management
services, we may receive significant liability claims. Our agreements with
customers typically contain provisions intended to limit our exposure to
liability claims. These limitations may not, however, preclude all potential
claims.

  Liability claims could require us to spend significant time and money in
litigation or to pay significant damages. As a result, any such claims, whether
or not successful, could seriously damage our reputation and our business.

  Our remote network management service for WANs generally includes a guarantee
that the customer's end-to-end network will be available for at least 99.5% of
the time in any given month. If this guaranteed level of availability is not
achieved for an end user, we may be required to refund all of our WAN
management fees

                                       11
<PAGE>


payable by the end user for that month. We may, in some instances, refund
amounts to customers for circumstances beyond our control.

Our existing stockholders will be able to control all matters requiring
stockholder approval and could prevent someone from acquiring or merging with
us.

  After this offering, our executive officers and directors collectively will
beneficially own approximately 58.3% of our outstanding common stock. Thus,
they will continue to control our company and, if they act together, could
elect all of the directors and control all matters submitted to our
stockholders for a vote. This could delay or prevent someone from acquiring or
merging with us on terms favored by a majority of our independent stockholders.

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

  The market price of our common stock could decline as a result of sales by
our existing stockholders of shares of common stock in the market after this
offering, or the perception that these sales could occur. These sales might
also make it more difficult for us to sell equity securities at a time and at a
price that we deem appropriate.

  We intend to file a registration statement approximately 90 days after the
completion of this offering covering 3,850,000 shares subject to outstanding
options or reserved for issuance under our stock plans.

Our management will have broad discretion in using the net proceeds of this
offering.

  We expect to use our net proceeds from this offering for general corporate
purposes, giving our management broad discretion in the allocation of the net
proceeds. Possible uses of these funds could include acquisitions of, or
investments in, complementary business and technologies. The failure of our
management to apply such funds effectively could seriously damage our business.

Anti-takeover provisions in our charter documents and Delaware law could
prevent or delay a change in control of our company.

  Our board of directors will be able to use a number of mechanisms that could
make it more difficult for a third party to acquire control of our company,
even if a change of control might be beneficial to our stockholders. These
mechanisms include:

  .  the denial of cumulative voting contained in our charter, which could
     make it more difficult to replace the board of directors;

  .  the provisions of the Delaware anti-takeover law that can be used to
     discourage certain business combinations;

  .  the issuance of series of preferred stock in connection with share
     rights plans or otherwise, pursuant to the "blank check" preferred stock
     provisions of our charter, with disproportionate voting rights or other
     features that could thwart a change of control; and

  .  the acceleration of the vesting of options or other incentive
     compensation, in a manner that could make a business combination
     significantly more expensive to conclude.

Investors will suffer dilution and may never be paid dividends.

  Since our common stock has in the past been sold at prices substantially less
than the public offering price that you will pay, you will suffer immediate
dilution of $8.36 per share in pro forma net tangible book value. The exercise
of outstanding options and warrants may result in further dilution. We do not
currently anticipate paying cash dividends in the foreseeable future.

                                USE OF PROCEEDS

  We estimate the net proceeds from our sale of 3,500,000 shares of common
stock will be approximately $38.3 million ($44.5 million if the underwriters'
over-allotment is exercised in full), assuming a public offering price of
$12.00 per share and after deducting the estimated underwriting discounts and
commissions and estimated offering expenses payable by us. We estimate that our
expenses in connection with this offering will total approximately $800,000. We
will not receive any proceeds from the sale of shares of common stock by the
selling stockholders.

  The principal purposes of this offering are to:

  .increase our capitalization and financial flexibility;

  .increase our visibility in the marketplace;

  .provide a public market for our common stock;

  .facilitate our future access to public equity markets; and

  .provide liquidity for our existing stockholders.

   We believe that our enhanced financial position will provide us with needed
flexibility to respond to technological and market developments as well as
other future opportunities. We also believe that our completion of this
offering will improve our ability to attract and retain customers and
employees.

  We intend to use our net proceeds from this offering for general corporate
purposes, including working capital and possible acquisitions of, and
investments in, complementary businesses and technologies. We are not currently
involved in negotiations with respect to, and we have no agreement or
understanding regarding, any such acquisition or investment. Accordingly, we
will have broad discretion in the application of our net proceeds. Pending
these uses, we intend to invest our net proceeds in short-term, investment-
grade, interest-bearing securities.

                                DIVIDEND POLICY

  We have never declared or paid any cash dividends on our capital stock. We
intend to retain all available funds and any future earnings for use in the
operation of our business. Therefore, we do not anticipate paying any cash or
other dividends in the foreseeable future. Payment of future dividends, if any,
will be at the discretion of our board of directors after taking into account
various factors, including our financial condition, results of operations,
current and anticipated cash needs, and plans for expansion.

                                    DILUTION

  The pro forma net tangible book value of our common stock as of June 30, 1999
was $10.4 million, or $1.06 per share. Pro forma net tangible book value per
share represents the amount of total tangible assets less total liabilities,
divided by the total pro forma number of shares of common stock outstanding,
after giving effect to the conversion of all of the outstanding shares of our
preferred stock into common stock. After giving effect to the sale of 3,500,000
shares of common stock offered by us in this offering at an assumed public
offering price of $12.00 per share, and after deducting the estimated
underwriting discounts and commissions and estimated offering expenses payable
by us, the adjusted pro forma net tangible book value at June 30, 1999, would
have been approximately $48.7 million, or $3.64 per share. This amount
represents an immediate increase in pro forma net tangible book value of $2.58
per share to existing stockholders and an immediate dilution in pro forma net
tangible book value of $8.36 per share to new investors. The following table
illustrates this per share dilution:

number of shares of common stock outstanding after this offering (or 69%, if
the underwriters' overallotment option is exercised in full) and will increase
the number of shares of common stock held by new investors to 3,700,000, or 28%
of the total number of shares of common stock outstanding after this offering
(or 4,255,000, or 31%, if the underwriters' overallotment option is exercised
in full).

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

  This prospectus contains forward-looking statements which involve risks and
uncertainties. Actual results could differ materially from those anticipated in
these forward-looking statements.

Overview

  We provide network management services that allow enterprises and carriers to
selectively outsource, or "out-task," network-specific activities in order to
increase network reliability and up-time, reduce overall network costs, and
simplify timely migration to new technologies. We were incorporated in
September 1985 in the State of Delaware and began operating in the second half
of 1987. Until December 1996, substantially all of our services revenues were
derived from the sale of data transport services. To provide these transport
services, we leased network transmission facilities from major carriers, and we
also resold AT&T's transport services. We began developing our first remote
network management service offering for WANs in early 1993 and began offering
that service, together with AT&T's transport services, in the quarter ended
March 31, 1994. We began selling network management services separately from
our data transport services in the quarter ended March 31, 1995. We introduced
our first security service in the quarter ended September 30, 1996. We
discontinued our data transport business in the quarter ended December 31,
1996. We began offering network management services for LANs in the quarter
ended June 30, 1997.

 Revenues

  Our revenues consist of network management services revenues as well as
equipment resales and other revenues. Our network management services include
both recurring and nonrecurring revenues:

  . Revenues from recurring services represent monthly fees charged to
    resellers or end users for our network management services. Recurring
    network management services revenues are typically based on the
    number of devices under management and are recognized in the period
    in which the services are rendered. In fiscal year 1999, 67% of
    network management services revenues were from recurring services.

  . Non-recurring network management services consist of data network
    design, project implementation services and equipment installation
    services, as well as one-time project and development assignments
    that assist resellers in defining and creating new network management
    services. Non-recurring network management services revenues are
    generally recognized upon completion of the assignment or service.
    For example, we charge fees for project implementation services on a
    per-location basis and we recognize revenues associated with such
    services upon completion of the network implementation for a
    location.

  Our network management services revenues are derived from contracts with
telecommunications carriers, value-added resellers of networking equipment and
services, and enterprises sold to by our direct sales force. Typical contracts
for our services include an initial implementation fee plus a fixed monthly fee
per managed device. Our contracts with end users are generally for terms of 24
to 36 months, although customers may cancel services prior to the end of the
service terms. Cancellations due to reasons other than closings of managed
locations, which to date have not been material, are generally subject to
cancellation fees ranging from 20% to 80% of the recurring charges payable for
the remainder of the service term. We recognize revenues from cancellation fees
on a cash basis unless collection is assured. Our contracts with resellers
typically extend from 12 to 36 months and, in some cases, require that we
continue providing services throughout the term of the reseller's contract with
the end user. In these cases, we continue to recognize revenues upon
performance of the services, even if performance occurs after the term of the
contract with the reseller.

  Our network management services for WANs typically include a guarantee
providing end-to-end network availability for at least 99.5% of the time in any
given month. In the event the guaranteed availability is not achieved, we
generally are obligated to refund our WAN management fees for that month. This
guarantee covers some components of the end user's WAN, such as the transport
services provided by the end user's carrier, that are not directly under our
control. As a result, we may, in some instances, refund amounts to customers
for circumstances beyond our control. We establish a reserve against guarantees
we offer. Guarantee payments have not been significant in any month, other than
in May 1998 when a major carrier's network was inoperable for an extended
number of hours. In order to enhance our relationships with direct customers
using that carrier's service, we refunded all of the management fees for that
month to those direct customers, even though the outage was outside the
coverage of our guarantee. The cost of that refund was $64,000. In the future,
refunds made under our guarantees or otherwise could have a material adverse
impact on the results of our operations.

  We derive equipment and other revenues from the resale of customer premise
equipment, or CPE, and from the sale of CPE maintenance contracts to our
network management services customers. We recognize revenues from the sale of
CPE upon shipment to the end user. However, if the transaction is financed
through our lease financing subsidiary, we recognize the revenues upon sale of
the underlying lease contract on a non-recourse basis. We recognize revenues
from CPE maintenance contracts on a monthly basis as the services are provided.
We expect to limit discounts on CPE and encourage end users to purchase
equipment from other sources. Further, as an alternative to selling CPE to our
resellers, we have recently amended some of our reseller agreements such that
we receive management fees for ordering CPE and managing CPE inventories for
these resellers. We therefore anticipate that revenues from CPE sales will
decline as we seek to manage our mix of revenues.

  We currently have a network management services contract with two business
units within AT&T: AT&T Solutions and AT&T Business Network Services. AT&T
accounted for 30% of our total revenues in fiscal year 1997, 52% of our total
revenues in fiscal year 1998, 59% of our total revenues in fiscal year 1999 and
69% of our total revenues in the three months ended June 30, 1999. We
anticipate that sales to AT&T will continue to comprise a substantial
percentage of our revenues at least through fiscal year 2000 and it is possible
that this percentage could increase. No other customer accounted for more than
10% of our revenues in fiscal year 1997, 1998 or 1999 or in the three months
ended June 30, 1999.

  Historically, we have generated substantially all of our revenues from sales
to customers in the United States, although we manage devices in several
locations around the world for these U.S.-based customers.

 Costs and expenses

  In March 1998, we relocated all of our operations from our previous facility,
consisting of approximately 25,000 square feet leased at prices negotiated
originally in 1991 which were substantially below current market rates in 1998,
into a new leased facility of approximately 70,000 square feet. Concurrent with
this move, we upgraded our computing and network management infrastructure
environment. The impact of these changes increased costs by approximately
$300,000 per quarter. These costs are allocated across the cost of network
management services revenues, development, sales and marketing, and general and
administrative expenses.

  As of March 31, 1999, we had net operating loss carryforwards of
approximately $17.2 million available to offset future net income for U.S.
federal income tax purposes. These net operating loss carryforwards will expire
beginning in 2004 if not utilized. We have alternative minimum tax credit
carryforwards of $196,000 which do not expire. Our utilization of these net
operating loss and tax credit carryforwards may be subject to a substantial
annual limitation due to the "change in ownership" provisions of the Internal
Revenue Code. The annual limitation may result in the expiration of the net
operating losses before utilization. We have provided a full valuation
allowance on the deferred tax asset at March 31, 1999 because of the
uncertainty regarding its realization. In concluding that a full valuation
allowance was required, we primarily considered factors such as our history of
operating losses, our potential future losses and the nature of the deferred
tax assets.

 Discontinued operations

  In December 1996, we decided to discontinue our data transport services
business segment and we sold a portion of that segment to Intermedia
Communications Inc. of Florida. The sale to Intermedia was closed on December
30, 1996 at a price of $12.3 million. As a part of this transaction, we
assigned to Intermedia all customer and supplier contracts related to a portion
of the business segment and we sold to Intermedia the capital equipment related
to this portion of the business segment. The agreement for this sale contains a
non-compete provision which prohibits us from competing in the data transport
business for five years. To ease the transition associated with this sale, we
agreed to provide management services to the transferred customer base through
October 1997. We recorded related revenues of $500,000 in fiscal year 1997,
$715,000 in fiscal year 1998 and $0 in fiscal year 1999, with respect to these
services. To complete the discontinuance of this business segment, on October
1, 1997, we assigned our rights and obligations to customer and supplier
contracts for other transport services to NetPlus, Inc. The purchase price,
initially established at 25% of NetPlus' gross profit from these services for a
period of three years beginning April 1, 1998 up to a maximum of $600,000, was
renegotiated to be a single payment of $100,000, which was received in fiscal
year 1999.

Three months ended June 30, 1998 compared to three months ended June 30, 1999

 Revenues

  Total revenues. Total revenues increased 63%, from $5.6 million in the three
months ended June, 30 1999 to $9.1 million in the three months ended June 30,
1999.

  Network management services. Revenues from network management services
increased 77%, from $2.6 million in the three months ended June 30, 1998 to
$4.6 million in the three months ended June 30, 1999, representing 46% of total
revenues in the three months ended June 30, 1998 and 51% of total revenues in
the three months ended June 30, 1999. The dollar and percentage increases
resulted primarily from a growth in the number of managed devices under
contract, increased implementation revenues and, to a lesser extent, increased
installation revenues resulting from higher volumes of CPE sales.

  Equipment and other. Revenues from equipment and other increased 50%, from
$3.0 million in the three months ended June 30, 1998 to $4.5 million in the
three months ended June 30, 1999, primarily as a result of increased purchases
of CPE by AT&T and, to a lesser extent, an increase in the number of equipment
maintenance contracts in place. We expect to limit discounts on CPE and
encourage end users to purchase equipment from other sources. Further, as an
alternative to selling CPE to our resellers, we have recently amended some of
our reseller agreements such that we receive management fees for ordering CPE
and managing CPE inventories for these resellers. We therefore anticipate that
revenues from CPE sales will decline as we seek to manage our mix of revenues.

 Cost of revenues

  Cost of network management services. Cost of network management services
includes salary and other costs of personnel, depreciation of equipment
utilized to manage customer networks, the network management infrastructure
utilized to provide remote network management services, and the costs of third-
party providers of CPE installation services. Cost of network management
services is expensed as incurred. Cost of network management services increased
50%, from $1.8 million in the three months ended June 30, 1998 to $2.7 million
in the three months ended June 30, 1999, representing 71% of network management
services revenues in the three months ended June 30, 1998 and 58% of such
revenues in the three months ended June 30, 1999. The dollar increase was due
primarily to the addition of personnel to accommodate growth, upgrades to the
network management infrastructure and, to a lesser extent, increased
subcontractor costs related to installation of CPE. The percentage decrease was
due primarily to improvements in processes and tools which have resulted in a
higher number of managed devices per operations employee.

  Cost of equipment and other. Cost of equipment and other includes the
purchase of CPE from manufacturers and distributors, maintenance contracts
purchased for resale to end users, and capital equipment maintained by us for
replacement of failed units. These costs are expensed in the period the related
revenues are recognized, other than costs associated with capital equipment
maintained by us for the replacement of failed units. The cost of replacement
units is amortized generally over three years, with the unamortized balance
expensed when the replacement unit is used. Cost of equipment and other
increased 52%, from $2.3 million in the three months ended June 30, 1998 to
$3.5 million in the three months ended June 30, 1999, representing 77% of
equipment and other revenues in the three months ended June 30, 1998 and 79% of
such revenues in the three months ended June 30, 1999. The increase in dollars
and as a percent of equipment and other revenues was due to higher volume of
CPE sales in the three months ended June 30, 1999 to our resellers at lower
resale margins. This increase in cost was partially offset by a higher
percentage of these revenues coming from maintenance services, which typically
have higher gross margins than CPE sales.

 Operating expenses

  Development. Development expenses consist primarily of salaries and related
costs of development personnel, including contract programming services.
Development employees are responsible for developing

                                       22
<PAGE>


internal software systems, selecting and integrating purchased software
applications, developing software tools for our network management services,
developing our web-enabled software applications that give customers access to
network management information, and defining and developing operating processes
for new services. Development expenses increased 30%, from $446,000 in the
three months ended June 30, 1998 to $579,000 in the three months ended June 30,
1999, representing 8% of total revenues in the three months ended June 30, 1998
and 6% of total revenues in the three months ended June 30, 1999. The increase
in dollars was due to an increase in the number of software and service
development personnel devoted to the development and enhancement of network
management tools and our network management services. The decrease as a
percentage of total revenues was affected by our decision to manage development
spending to a lower level as a percentage of total revenues. The decrease was
also affected by higher than anticipated equipment revenues in the three months
ended June 30, 1999. We anticipate that development costs may increase as a
percentage of total revenues over the remainder of fiscal year 2000 as
additional development personnel are added.

  Sales and marketing. Sales and marketing expenses consist primarily of
salaries, commissions, travel and costs associated with creating awareness of
our services. Sales and marketing expenses increased 28%, from $739,000 in the
three months ended June 30, 1998 to $943,000 in the three months ended June 30,
1999, representing 13% of total revenues in the three months ended June 30,
1998 and 10% of total revenues in the three months ended June 30, 1999. The
increase in dollars was due to increased spending for advertising and other
promotional activities, as well as costs associated with the recruiting and
relocation of a new vice president of marketing. The decrease of sales and
marketing expenses as a percentage of total revenues reflects the increase in
total revenues and a move to reduce these expenditures as a percentage of total
revenues as we began to rely more on an indirect distribution strategy. We
anticipate that sales and marketing costs may increase slightly as a percentage
of total revenues over the remainder of fiscal year 2000, as additional sales
and marketing personnel are added.

  General and administrative. General and administrative expenses consist
primarily of expenses related to our human resources, finance and executive
departments. Included in human resources spending is all employee training
sponsored by us, as well as most costs of recruiting and relocating new
employees. General and administrative expenses increased 15%, from $541,000 in
the three months ended June 30, 1998 to $622,000 in the three months ended June
30, 1999, representing 10% of total revenues in the three months ended June 30,
1998 and 7% of total revenues in the three months ended June 30, 1999. The
dollar increase was due primarily to additional spending related to recruiting
of new employees. The decrease as a percentage of total revenues is primarily
the result of higher total revenues in the three months ended June 30, 1999.

 Other income, net

  Other income, net consists primarily of interest expense from our leases for
capital equipment, offset by interest income earned on our cash balances. Other
income, net remained relatively flat, decreasing from $48,000 in the three
months ended June 30, 1998 to $46,000 in the three months ended June 30, 1999,
representing approximately 1% of total revenues in both periods.

Fiscal year ended March 31, 1998 compared to fiscal year ended March 31, 1999

 Revenues

  Total revenues. Total revenues increased 84%, from $14.5 million in fiscal
year 1998 to $26.7 million in fiscal year 1999.

  Network management services. Revenues from network management services
increased 75%, from $7.3 million in fiscal year 1998 to $12.8 million in fiscal
year 1999, representing 50% of total revenues in fiscal year 1998 and 48% of
total revenues in fiscal year 1999. The dollar increase resulted primarily from
a growth in the number of managed devices under contract, increased
implementation revenues and, to a lesser extent,

                                       23
<PAGE>


increased installation revenues resulting from higher volumes of CPE sales.
Increased implementation fees in fiscal year 1999 were largely due to a change
in company policy in the quarter ended March 31, 1998 which resulted in our
charging fees for, rather than absorbing the costs of, implementing new
networks. These increases were partially offset by a decrease in the fiscal
quarter ended December 31, 1997 in the revenues attributable to the management
of the customer base sold to Intermedia. The percentage of revenues from
network management services derived from our relationship with AT&T was
approximately equal to the percentage of total revenue derived from AT&T.

  Equipment and other. Revenues from equipment sales and other increased 93%,
from $7.2 million in fiscal year 1998 to $13.9 million in fiscal year 1999,
primarily as a result of increased purchases of CPE by AT&T and, to a lesser
extent, an increase in the number of equipment maintenance contracts in place.

 Cost of revenues

  Cost of network management services. Cost of network management services
increased 46%, from $5.7 million in fiscal year 1998 to $8.3 million in fiscal
year 1999, representing 78% of network management services revenues in fiscal
year 1998 and 65% of such revenues in fiscal year 1999. The dollar increase was
due primarily to the addition of personnel to accommodate growth, upgrades to
the network management infrastructure including the addition of a separate
infrastructure support group, the upgrade of our facilities, and, to a lesser
extent, increased subcontractor costs related to installation of CPE. The
percentage decrease was due primarily to improvements in processes and tools
which have resulted in a higher number of managed devices per operations
employee.

  Cost of equipment and other. Cost of equipment and other increased 98%, from
$5.4 million in fiscal year 1998 to $10.7 million in fiscal year 1999,
representing 75% of equipment and other revenues in fiscal year 1998 and 77% of
such revenues in fiscal year 1999. The increases in dollars and as a percent of
equipment and other revenues were due to higher volume of CPE sales in fiscal
year 1999 to our resellers at lower resale margins. These increases in cost
were partially offset by a higher percentage of these revenues coming from
maintenance services, which typically have higher gross margins than CPE sales.

 Operating expenses

  Development. Development expenses were $1.9 million in both fiscal years 1998
and 1999, representing 13% of total revenues in fiscal year 1998 and 7% of
total revenues in fiscal year 1999. The decrease as a percentage of total
revenues was due to the development of our LAN product which was introduced in
the first quarter of fiscal year 1998 and reduced usage of third-party contract
programming resources. The decrease was also affected by our decision to manage
development spending to a lower level as a percentage of total revenues in
fiscal year 1999, after having accelerated spending in fiscal year 1998 in
order to support future revenue growth, cost reduction and service quality.
This decrease was partially offset by increased depreciation on development
tools.

  Sales and marketing. Sales and marketing expenses increased 23%, from $2.6
million in fiscal year 1998 to $3.2 million in fiscal year 1999, representing
18% of total revenues in fiscal year 1998 and 12% of total revenues in fiscal
year 1999. In fiscal year 1999, total sales and marketing salaries paid
increased as additional people were added to support resellers and to focus on
new product definition. This dollar increase was offset by cost savings
realized from centralizing all sales activities in our headquarters in Austin.
This centralization eliminated the costs of remote sales offices and more than
offset the additional costs associated with the move to the new headquarters
facility in March 1999. The decrease of sales and marketing expenses as a
percentage of total revenues reflected the increase in total revenues and a
move to reduce these expenditures as a percentage of total revenues as we began
to rely more on an indirect distribution strategy.

                                       24
<PAGE>


  General and administrative. General and administrative expenses decreased 5%,
from $2.2 million in fiscal year 1998 to $2.1 million in fiscal year 1999,
representing 15% of total revenues in fiscal year 1998 and 8% of total revenues
in fiscal year 1999. The decreases in dollars and as a percentage of total
revenues were due primarily to decreased legal and consulting fees and outside
recruiting and relocation fees. These decreases were offset by increased
salaries related to the addition of human resource professionals who are
responsible for enhancing training and recruiting programs in preparation for
growth.

 Other income, net

  Other income, net decreased 4%, from $202,000 in fiscal year 1998 to $193,000
in fiscal year 1999, both representing 1% of total revenues in fiscal year 1998
and in fiscal year 1999. The dollar decrease in fiscal year 1999 was due to
higher interest income in fiscal year 1998 earned from a higher level of funds
available for investment and increased interest expense incurred on capital
lease obligations in fiscal year 1999. This dollar decrease was partially
offset by a recovery in fiscal year 1999 of a portion of certain contract
development expenses written off in fiscal year 1998.

Fiscal year ended March 31, 1997 compared to fiscal year ended March 31, 1998

 Revenues

  Total revenues. Total revenues increased 130%, from $6.3 million in fiscal
year 1997 to $14.5 million in fiscal year 1998.

  Network management services. Revenues from network management services
increased 161%, from $2.8 million in fiscal year 1997 to $7.3 million in fiscal
year 1998, representing 45% of total revenues in fiscal year 1997 and 50% of
total revenues in fiscal year 1998. The dollar and percentage increases in
network management services revenues resulted primarily from a growth in the
number of managed devices under contract, increased implementation revenues
and, to a lesser extent, increased installation revenues resulting from higher
volumes of CPE sales. The impact of changes in average revenues per device was
not significant. Increased implementation fees in fiscal year 1998 were largely
due to a change in company policy in the quarter ended March 31, 1998 which
resulted in our charging fees for, rather than absorbing the costs of,
implementing new networks. These increases were partially offset by a decrease
in the three months ended December 31, 1997 in the revenues attributable to the
management of the customer base sold to Intermedia. The percentage of revenues
from network management services derived from our relationship with AT&T was
approximately equal to the percentage of total revenue derived from AT&T.

  Equipment and other. Revenues from equipment and other increased 106%, from
$3.5 million in fiscal year 1997 to $7.2 million in fiscal year 1998, primarily
as a result of increased sales of CPE.

 Cost of revenues

  Cost of network management services. Cost of network management services
increased 138%, from $2.4 million in fiscal year 1997 to $5.7 million in fiscal
year 1998, representing 86% of network management services revenues in fiscal
year 1997 and 78% of such revenues in fiscal year 1998. The dollar increase was
due primarily to the addition of personnel to accommodate growth, upgrades to
the network management infrastructure including the addition of a separate
infrastructure support group, facilities expansion to accommodate new
operations personnel, increased recruiting and relocation costs associated with
strengthening the management and technical talent of the operations groups and,
to a lesser extent increased subcontractor costs related to installation of
CPE. The percentage decrease was due primarily to a higher number of managed
devices per operations employee.

  Cost of equipment and other. Cost of equipment and other increased 108%, from
$2.6 million in fiscal year 1997 to $5.4 million in fiscal year 1998,
representing 76% of equipment and other revenues in fiscal year 1997 and 75% of
such revenues in fiscal year 1998. The dollar increase was due primarily to the
higher volume of CPE sales in fiscal year 1998 and, to a lesser extent,
increased equipment maintenance revenues.

 Operating expenses

  Development. Development expenses increased 46%, from $1.3 million in fiscal
year 1997 to $1.9 million in fiscal year 1998, representing 20% of total
revenues in fiscal year 1997 and 13% of total revenues in fiscal year 1998. The
dollar increase was due to higher development spending in fiscal year 1998
enabled by the sale of our transport business in the third quarter of fiscal
year 1997. This sale provided a source of working capital to invest in our
relatively new network management services offerings. These additional
development expenses included the costs associated with hiring additional
people, including additional facilities space. The decrease as a percentage of
total revenues was primarily the result of higher total revenues in fiscal year
1998.

  Sales and marketing. Sales and marketing expenses increased 18%, from $2.2
million in fiscal year 1997 to $2.6 million in fiscal year 1998, representing
36% of total revenues in fiscal year 1997 and 18% of total revenues in fiscal
year 1998. This dollar increase was due to one-time costs, including accrual of
future rentals on vacated spaces, related to the closing of most of our remote
sales offices as we began consolidating sales efforts at our Austin
headquarters as well as increased public relations and market awareness
efforts. The decrease as a percentage of total revenues reflected the increase
in recurring network management services revenues and a move to reduce these
sales and marketing expenditures as a percentage of total revenues as we began
to rely more on an indirect distribution strategy.

  General and administrative. General and administrative expenses increased
47%, from $1.5 million in fiscal year 1997 to $2.2 million in fiscal year 1998,
representing 24% of total revenues in fiscal year 1997 and 15% of total
revenues in fiscal year 1998. The dollar increase was due primarily to the
addition of human resources professionals beginning in the first quarter of
fiscal year 1998 who were responsible for enhancing training and recruiting
programs in preparation for growth. The dollar increase was also due to a
lesser extent to additional facilities space, additional spending for outside
training programs and increased recruiting costs. The decrease as a percentage
of total revenues was primarily the result of higher total revenues in fiscal
year 1998.

 Other income, net

  Other income, net increased 494%, from $34,000 in fiscal year 1997 to
$202,000 in fiscal year 1998, representing 1% of total revenues in both fiscal
year 1997 and fiscal year 1998. The dollar increase in fiscal year 1998 was due
to higher interest income in fiscal year 1998 earned from a higher level of
funds available for investment, offset by a write-off of contract development
expenses and increased interest on capital lease obligations in fiscal year
1998.

Quarterly results of operations

  Although our total revenues have increased in each of the last nine quarters,
results of operations have varied from quarter to quarter. Accordingly, we
believe that period-to-period comparisons of results of operations are not
necessarily meaningful and should not be relied upon as indications of future
performance. Our operating results may fluctuate as a result of many factors,
including our ability to renew or retain existing end-user and reseller
relationships, the cost of introducing new service offerings and the
profitability of such offerings, and the level and nature of competition.
Further, we may be unable to adjust spending rapidly enough to compensate for
any significant fluctuations in the number of new managed devices implemented
in a given period. Any significant shortfall in the number of new managed
devices could therefore seriously damage our business. Finally, there can be no
assurance that we will be profitable in the future or, if we are profitable,
that our levels of profitability will not vary significantly between quarters.

  The following tables set forth quarterly statement of operations data in
dollars and, except as noted below, as a percentage of total revenues for each
of the nine quarters in the period ended June 30, 1999. This quarterly
information is unaudited and has been prepared on the same basis as our audited
annual consolidated financial statements and, in the opinion of our management,
includes all adjustments consisting only of normal recurring adjustments that
we consider necessary for a fair presentation of the information for the
periods presented. The information should be read together with the
consolidated financial statements and related notes appearing elsewhere in this
prospectus. Operating results for any quarter are not necessarily indicative of
results for any future period.

  The trends discussed in the annual comparisons of operating results from
fiscal year 1998 to fiscal year 1999 and the three months ended June 30, 1998,
to the three months ended June 30, 1999 are generally applicable to the
comparison of quarters within the nine quarters in the period ended June 30,
1999. The following supplemental explanations are provided with respect to
significant sequential changes in amounts.

  The relatively slower sequential growth of network management services
revenues in the quarter ended December 31, 1997 was due to the expiration of
the contract with Intermedia under which we managed the

                                       28
<PAGE>


customer base of the discontinued transport business. The larger than usual
sequential growth in equipment and other revenues in the three months ended
June 30, 1998 was due primarily to increased sales of network management
services to AT&T, which included higher volumes of CPE sales.

  The increase in cost of equipment and other as a percent of equipment and
other revenues in the quarter ended June 30, 1998 was due primarily to a higher
mix of CPE sales. We expect to limit discounts on CPE and encourage end users
to purchase equipment from other sources. Further, as an alternative to selling
CPE to our resellers, we have recently amended some of our reseller agreements
such that we receive management fees for ordering CPE and managing CPE
inventories for these resellers. We therefore anticipate that revenues from CPE
sales will decline as we seek to manage our mix of revenues.

  The fluctuations in general and administrative expenses on a quarter-to-
quarter basis reflect periodic changes in amounts spent for training,
recruiting and relocation, and consulting services.

Liquidity and capital resources

  Since our inception we have funded our operations primarily through:

  . private sales of capital stock totaling $28.3 million, including our
    most recent sale of capital stock in fiscal year 1993 for $9.8
    million;

  . the sale of our discontinued transport business for $12.3 million in
    December 1996;

  . leases on capital equipment;

  . working capital lines of credit; and

  . cash provided by operations of $1.1 million in fiscal year 1995, $1.0
    million in fiscal year 1996, $892,000 in fiscal year 1999 and $1.5
    million in the three months ended June 30, 1999.

  We used $1.5 million in cash during fiscal year 1997, $2.2 million during
fiscal year 1998, $1.6 million during fiscal year 1999, and $724,000 in the
first three months of fiscal year 2000 to purchase capital assets primarily
used in the delivery of our network management services. We currently have no
material commitments for capital expenditures. Proceeds from leases of capital
equipment totaled $218,000 in fiscal year 1997, $1.7 million in fiscal year
1998, $831,000 in fiscal year 1999, and $0 in the first three months of fiscal
year 2000. We paid $514,000 in 1997, $257,000 in 1998, $732,000 in 1999 and
$249,000 in the first three months of fiscal year 2000 toward our lease
obligations for capital equipment. We intend to continue to add sales,
marketing and development resources over the next 12 months; however, we
anticipate that costs associated with sales, marketing and development
initiatives will not materially increase as a percentage of revenues and will
not result in significant uses of working capital.

  In July 1999, we completed a conversion of our financial and accounting
system for accounts payable, accounts receivable and general ledger accounts,
in order to make the system year 2000 compliant. With the exception of routine
upgrades to certain server and desktop computer operating systems, desktop
computer packaged software, desktop computer firmware and one third-party
software tool, all of our internal, mission-critical systems, including the
software tools we supply to customers, are year 2000 compliant. Resellers', end
users' and vendors' software and systems, however, may not be year 2000
compliant. The failure of systems maintained by our resellers, end users and
vendors to be year 2000 compliant could cause us to incur significant expenses
to remedy any problems, reduce our revenues from such end users, or otherwise
have a material adverse effect on our business, financial condition and results
of operations.

  We have not incurred significant costs to date complying with year 2000
requirements, and we do not believe that we will incur significant costs for
such purposes in the foreseeable future. We expect to spend less than $100,000
to complete all remaining hardware and software upgrades in order to be year
2000 compliant. However, any disruption of our operations or additional
unanticipated expenses could have an adverse effect on our business, financial
condition and results of operations.

  In December 1996, we terminated our $1.0 million bank line of credit prior to
the closing of the sale of the transport business. If desirable, we believe we
can obtain a similar working capital line of credit on acceptable terms.


                                       29
<PAGE>


  As of June 30, 1999, we had $6.6 million in cash and cash equivalents and
$3.4 million in net accounts receivable. We believe that the net proceeds from
this offering, together with cash generated from operations, will be sufficient
to fund our anticipated working capital needs, capital expenditures and any
potential future acquisitions for at least 12 months. In the event our plans or
assumptions change or prove to be inaccurate, or if we consummate any unplanned
acquisitions of businesses or assets, we may be required to seek additional
sources of capital. Sources of additional capital may include public and
private equity and debt financings, sales of nonstrategic assets and other
financing arrangements.

                                    BUSINESS

  We offer a range of network management and security services that allow
companies to selectively outsource, or "out-task," specific network activities
in order to increase network reliability and up-time, reduce overall network
costs, and simplify timely migration to new technologies. Our management
services are intended to address all or selected parts of the full life cycle
of network management, which consists of network design, configuration,
implementation, monitoring, fault diagnosis, fault resolution, reporting,
upgrading and documentation. We furnish our network management services
remotely 24 hours per day, seven days per week from our network management
center in Austin, Texas, and we offer software tools that allow companies to
access up-to-date network status reports through standard web browsers. We also
offer around-the-clock remote security protection services for the Internet and
intranet perimeter points of our customers' networks. Our security offerings
currently include a managed firewall service and a remote intrusion detection
and response service. We have offered network management services since 1995
and currently have over 575 end users representing approximately 8,700 managed
sites. We target middle market enterprises, and provide services both directly
to end users as well as indirectly through resellers such as AT&T.

Industry background

  Businesses increasingly depend on the ability to access and share electronic
information reliably. To enable effective internal communication, more and more
companies are relying on client/server-based databases and applications, e-
mail, remote access by mobile workers and various forms of online information.
The proliferation of the use of the Internet and the emergence of e-commerce
are driving the need for businesses to exchange electronic information
externally with customers, business partners and vendors. In response to the
growing need to share information internally and externally, companies'
operations increasingly depend on data networks, including both wide area
networks, or WANs, which allow companies to communicate with a large number of
computers over a broad geographic area, and local area networks, or LANs, which
are generally more limited in the number of computers in the network and the
geographic area covered. This proliferation of networks has resulted in a
dramatic increase in network traffic as well as heightened requirements for
network performance. It has also increased the magnitude of sensitive corporate
information shared over networks, causing network security to become a high
priority for many businesses. As a result of these trends, a growing number of
businesses view responsive, reliable and secure networks as mission-critical to
their operations.

  As networks have become a more integral part of day-to-day operations, many
companies are seeking to control network costs and improve operating
efficiencies. Economic and performance issues are especially important for
organizations operating WANs to connect geographically dispersed sites.
Providers of WAN equipment and services have responded to customer demand by
introducing switched data technologies which allow any user to be connected to
any other user in a more efficient manner than traditional network
architectures. Examples of these switched data technologies include Frame
Relay, Asynchronous Transfer Mode, or ATM, and Internet Protocol, or IP. These
new switched data technologies are able to share and allocate bandwidth, the
electronic frequencies used to transmit data over computer networks, based on
actual network use, while traditional network architectures use fixed bandwidth
and dedicated circuits regardless of network use. The shared bandwidth of
switched data technologies typically results in WANs that are more reliable and
less expensive than those based on traditional leased-line services. As a
result, switched data services have grown rapidly since WAN service providers
initially introduced Frame Relay services as a solution. ATM services, a
switched data technology characterized by higher capacities and higher speeds,
are less widely offered today but are expected to compete with Frame Relay and
experience rapid growth in the next several years. Likewise, services based on
IP are becoming an important option to the traditional dedicated circuit WAN
infrastructure.

  The growth of the switched data market has been enabled by the rapid
development of sophisticated networking hardware such as routers, inverse
multiplexers and switches. At the same time, software companies have introduced
network management and security software designed to work with and optimize the
new hardware. Implementation and management of new hardware and software
technologies typically require significant expertise in order to maintain
reliability, performance and security, especially since networks have grown
more complex and heterogeneous as new technologies have been integrated with
legacy networks.

                                       31
<PAGE>


Further, the tools available to manage today's networks are complex and often
require incremental investments in hardware, software, personnel and training.
The proliferation of services available from WAN service providers, such as the
major telecommunications carriers, further complicates network management and
security.

  Many companies have encountered difficulties implementing and managing
networks internally because of the significant shortage of qualified networking
and information technology, or IT, professionals. We estimate, based on
industry reports, that between 15% and 30% of permanent IT positions were
unfilled in mid-1998. The United States Department of Commerce, in a report
released in June 1999, projects 75% growth in the demand for core IT
occupations in the decade ending in 2006 as compared to 14% growth in demand
for all occupations. Maintaining internal IT staffs is costly since network
management skills must be constantly upgraded to respond to the rapid changes
in networking and security technologies. This situation is even more acute in
the area of network security, an area that is increasing in importance due to
threats of security attacks via the Internet as well as rapidly changing
security technology. The resource scarcity and high cost of internal IT staffs
represent significant challenges for businesses, especially mid-sized companies
that are large enough to require sophisticated networks, but too small to gain
efficiencies of scale achievable by a large enterprise that can amortize the
costs of an in-house IT network management group across a large organization.

  Many companies are beginning to turn to third-party service providers for
network management and security, particularly when those skills are not core
business competencies. While some companies out-source their entire computing
environment, a growing number of companies are managing their computing
environments more actively and affordably by out-tasking a particular set of
activities. Businesses seeking to out-task network management services
typically need to migrate quickly to newer technologies as they become
available, increase the reliability of their networks and reduce the overall
cost of managing their networks. Further, these businesses' networks must be
available to internal and external users 24 hours per day, seven days per week.
Even if network management activities are out-tasked, internal IT managers need
access to network information and performance reporting at all times. In
addition, network security must be assured, with access to the networks limited
to authorized users, and then only to those applications and data for which the
users have been authorized. All of this network management must be done in an
environment of constant and rapid change in networking and security technology
where the time to implement new technologies can affect the time to market of
new products and services.

Our solution

  We offer network management services that allow customers to out-task
network-specific activities in order to increase network reliability and up-
time, reduce overall network costs and migrate to new technologies and services
on a timely basis. We also offer security protection for network perimeter
points such as an enterprise's Internet or intranet connections. Our solutions
are designed to address the needs of middle market enterprises. We currently
have over 575 middle market end users that maintain approximately 8,700 managed
sites. We believe our solution offers the following key benefits:

  Full breadth of network management services. Our network management services
cover the entire life cycle of an enterprise's network, including network
design, configuration, implementation, monitoring, fault diagnosis, fault
resolution, reporting, upgrading and documentation. End users have the ability
to outsource all of their network requirements to us, or they can retain
control over certain aspects of their network and out-task only selected
network management tasks.

  Reduced costs. Substantial costs are incurred in retaining and maintaining an
internal IT staff that is qualified to manage a complex, multi-site network. We
are able to amortize these personnel-related costs, as well as costs of
necessary network infrastructure, software and tools, over hundreds of end
users. As a result, we believe we are able to offer a better network solution
at a lower cost than if an end user attempted to manage its network in-house.
Furthermore, we evaluate, purchase, develop and integrate application-specific
software and tools that allow us to deliver reliable solutions at low costs. We
support only the relatively small

                                       32
<PAGE>


number of providers of networking hardware and carrier services that
collectively dominate the market for such equipment and services. By focusing
on the leading equipment manufacturers and carriers, we are able to leverage
economies of scale in managing multiple end-user networks.

  Increased network reliability, security and up-time. As enterprises continue
to increase their use of networks for internal and external communication and
for conducting e-commerce, the need for reliable and secure networks becomes
more critical. We provide our remote network management and security services
to end-user locations worldwide 24 hours per day, seven days per week. Our
remote network management services for WANs generally include a guarantee to
provide end-to-end network availability for at least 99.5% of the time in any
given month.

  Ease of network maintenance and technology upgrades. Our network management
professionals act as an extension of the customer's IT staff. By relying on our
expertise, infrastructure and tools, end users are able to meet the challenges
posed by rapidly evolving technologies and move quickly and affordably to more
advanced network solutions as needed. We report to end users on an ongoing
basis and recommend upgrades or changes when appropriate.

  Web-enabled network monitoring and reporting. End users can out-task to us
the complex, frustrating and expensive responsibilities of dealing with day-to-
day network management and security issues, yet still be able to understand and
see their networks in operation. End users can access our web-enabled network
management and monitoring tools and view on their computer screens a network
map that gives a current status of every site on their networks. We also
provide end users with reports of network activity periodically or on demand.

Strategy

  Our goal is to be a leading provider of remote network management services.
The key elements of our strategy include the following:

  Target middle market enterprises. We believe that a significant market
opportunity exists for our services among enterprises that are large enough to
employ WANs across multiple sites, but too small to amortize the costs of an
in-house IT network management staff across a large organization. These middle
market companies, which typically have between 200 and 1,500 employees and
annual revenues between $50 million and $2.5 billion, are facing a growing need
for network expertise and technology. At the same time, they are encountering
increased difficulties in attracting qualified and affordable networking
professionals. We believe that our network management and security services
offer an attractive solution for many middle market companies and we intend to
target these companies, as we market our existing services and develop new
services.

  Support leading technologies. We have been able to provide cost-effective
solutions to our customers by supporting only the leading providers of
networking hardware and carrier services. The suppliers that we support include
AT&T, MCI/WorldCom, Qwest Communications and Sprint in the data transport
arena, and 3Com, Bay/Nortel, Cabletron and Cisco in the market for customer
premise equipment, or CPE. By designing our services to support this select
group of leading service and equipment vendors, we seek to leverage our
expertise, technologies and processes, while still providing support for the
needs of most middle market companies. We intend to continue to develop our
processes and tools to support new hardware and services introduced by leading
vendors. This ongoing support may require us to modify existing services and,
in some cases, develop new services. For example, we recently began managing
ATM devices and are actively attempting to define new value added services.

  Expand service offerings. We seek to expand our service offerings by
leveraging our existing expertise, technologies and processes in the network
management arena. In August 1996, we introduced a security service that
provides remote intrusion detection. In March 1999, we introduced an add-on
service to our WAN management

                                       33
<PAGE>


service that offers customers increased proactive network management
capabilities, including our ability to identify many network problems and
faults before the customer's network goes down. These offerings use our
network management center and tools infrastructure and are supplemented by
additional proprietary and third-party tools. In addition, the security
service is enhanced by engineers with specific network security expertise. In
the future, we intend to further develop our proactive network management
service involving performance engineering and to add services addressing
capacity planning.

  Add distribution partners. We believe that we can market our services to
middle market companies most effectively by partnering with resellers that
bundle our services with transport services or CPE. We believe that we can
expand our current distribution relationships to include other major carriers,
competitive local exchange carriers, or CLECs, and Internet service providers,
or ISPs, and that we can also establish sales referral relationships with
various manufacturers of networking hardware. We believe that these
relationships will provide us with a significant competitive advantage.

Network management services

  Our network management services include one-time services such as design and
implementation of new networks, as well as ongoing, or recurring, management
and security services. Our current service offerings are grouped under three
general categories: remote network management services, Internet and intranet
security services, and web-enabled network management tools.

 Remote network management services

  Our services include the remote management of router-based WANs and LANs,
LAN switches and intelligent hubs, as well as the monitoring of servers. These
services are intended to address the full life cycle of network management,
which includes the activities depicted below:

  We have two branded network management service packages: ProWatch for WANs
and ProWatch for LANs.

    ProWatch for WANs. We introduced our first WAN remote management
  service in January 1994 to enable remote management of router-based
  Frame Relay and ATM networks. This service is marketed by us and
  certain of our resellers as ProWatch for WANs. It is also marketed by
  other resellers, sometimes in modified versions, under the various
  brands of those resellers. The managed elements in this service include
  the WAN-attached router, the customer service unit, or CSU, connecting
  the router to the transport provider's Frame Relay or ATM service; and
  the transport provider's network services. Features offered in
  different options of ProWatch for WANs include: (1) performance
  engineering and fault management; (2) proactive monitoring; and (3)
  performance reporting. The ProWatch for WANs service generally includes
  a guarantee to provide the customer end-to-end network availability for
  at least 99.5% of the time in any given month, with the customer
  generally receiving a refund of the management fee in any month the
  guaranteed availability rate is not achieved. Substantially all of our
  recurring network management services revenues are derived from
  ProWatch for WANs and related WAN services.

    ProWatch for LANs. We introduced our LAN remote management service in
  May 1997 to measure, monitor and manage the routers, switches and
  intelligent hubs in corporate LANs. This

                                       35
<PAGE>


  service can also monitor the availability of servers manageable by the
  Simple Network Management Protocol, or SNMP. Our LAN management
  services are marketed by us and certain of our resellers as ProWatch
  for LANs and are also marketed by other resellers under the various
  brands of those resellers. In developing the ProWatch for LANs service,
  we leveraged the expertise, technologies and processes we developed in
  providing ProWatch for WANs. The primary differences between ProWatch
  for LANs and ProWatch for WANs are the exclusion of the transport
  provider's network services and the inclusion of additional performance
  reporting capabilities.

 Internet and intranet security services

  Our network security services, marketed under the brand name ProWatch Secure,
provide protection 24 hours per day, seven days per week for networks' Internet
and intranet perimeter points. This security service includes the following
elements of remote network security management: security assessment and
recommendations; implementation; ongoing security management; assurance;
security reports and consultation; configuration management; and virtual
private network, or VPN, configuration management. The pricing for these
security services is generally established as a monthly fee on a per-managed-
device basis. We offer two different security services:

    ProWatch Secure Managed Firewall Service. This service provides
  active management of the firewall, the electronic barrier between
  network segments. Our security engineers regularly review firewall logs
  and alarms to detect suspicious activity. Through this monitoring we
  can consult with the end user regarding potential changes in the
  firewall configuration. ProWatch Secure Managed Firewall Service is
  supported on Cisco's PIX Firewall series. The Cisco PIX Firewall is
  configured by our security engineers to enforce the security policy
  that best meets the end user's requirements to control access by
  specified applications and source addresses. The ProWatch Secure
  Managed Firewall Service was introduced in September 1998 as a more
  basic security service than our Remote Intrusion Detection and Response
  Service.

    ProWatch Secure Remote Intrusion Detection and Response Service. For
  more demanding security environments, such as those engaged in e-
  commerce, customers can implement intrusion detection monitoring as a
  second layer of network security. This service provides additional
  perimeter security beyond that offered by the access protection of
  ProWatch Secure Managed Firewall Service. ProWatch Secure Remote
  Intrusion Detection and Response Service uses Cisco's NetRanger
  intrusion detection system to detect suspicious activity on customer
  networks, repel attack attempts and bar the potential intruder from
  accessing the end user's network. We introduced our ProWatch Secure
  Remote Intrusion Detection and Response Service in August 1996.

  End users may purchase these services individually, together or as part of a
combined network management service offering.

 Web-enabled tools

  Our web-enabled network management tools provide end users with access to up-
to-date status information of their networks, giving end users greater control
and understanding of their networks while out-tasking day-to-day management to
us. End users access these tools through a standard web browser using our
ProWatch Exchange application. ProWatch Exchange provides trouble ticket status
and history, plus network installation project status. An active network map
displays the status of all managed sites in an end user's network. ProWatch
Exchange also provides on-line viewing access to the monthly availability and
performance reports included with the various remote network management
services.

Equipment and other services

  We resell customer premises equipment from leading network equipment
manufacturers or their resellers. This equipment typically includes routers,
CSUs and LAN switches and is obtained from Cisco and, to a lesser extent, from
3Com, Bay/Nortel, Paradyne and others.

                                       36

  We also resell on-site maintenance services. These services address issues
associated with hardware failures and software bugs, as well as software
upgrades provided for under the equipment provider's maintenance contract.
These maintenance services are provided by 3Com, Bay/Nortel, Cisco and Racal.

Customers

  Our solutions are designed to address the needs of middle market
enterprises, roughly defined as companies that have between 200 and 1,500
employees and annual revenues between $50 million and $2.5 billion. We
currently have over 575 middle market end users that maintain approximately
8,700 managed sites. Our end users consist of our direct customers as well as
customers of our resellers. The following is a selected list of our direct
customers grouped by industry.

  When sold to end users by resellers, our services are typically sold under
the reseller's trade or brand name. In some instances, however, the reseller
utilizes our brand names. Certain of our services sold to resellers are
provided directly to the reseller either to support the reseller's network, as
in the case of some carriers, or are embedded as a portion of a carrier
transport service sold to end users. Our resellers include AT&T, NEC Business
Network Solutions, e.spire Communications and Intermedia.

  We have derived a significant portion of our revenue from one reseller,
AT&T. No other customer accounted for more than 10% of our revenues in any of
the last three fiscal years. AT&T accounted for 30% of our total revenues in
fiscal year 1997, 52% of our total revenues in fiscal year 1998, 59% of our
total revenues in fiscal year 1999 and 69% of our total revenues in the three
months ended June 30, 1999. We anticipate that this concentration of revenue
from AT&T will continue at least through fiscal year 2000.

Relationship with AT&T

  We have developed marketing partnerships with two separate business units of
AT&T: AT&T Solutions and AT&T Business Network Services. Both of these
business units market our network management services to AT&T customers in
conjunction with AT&T's overall network solution offering. Our technicians
work directly with AT&T's sales and marketing personnel and the end users to
design, implement and manage the end users' networks. AT&T accounted for 30%
of our total revenues in fiscal year 1997, 52% of our total revenues in fiscal
year 1998, 59% of our total revenues in fiscal year 1999 and 69% of our total
revenues in the three months ended June 30, 1999. We anticipate that this
concentration of revenue from AT&T will continue at least through fiscal year
2000.



                                      37
<PAGE>


  We provide our services for AT&T customers under a written contract that has
separate terms for each of the two business units. The arrangements with AT&T
Solutions currently terminate on December 31, 2001 with respect to placing new
orders for service. Individual orders received prior to July 1, 1999 may be
canceled at AT&T's option at a rate not to exceed 150 devices per month
beginning in July 2000. This rate represents approximately 4% per month of the
orders eligible for this option as of June 30, 1999. For orders placed after
June 30, 1999, the agreement provides for us to continue providing services
until the earlier of the expiration of the end-user customer service term or
December 31, 2004. However, individual orders placed after June 30, 1999 may be
canceled at any time at AT&T's option on thirty days' notice by paying a
cancellation charge. Such cancellations are limited to ten percent of the
beginning backlog of all orders in any twelve month period. In addition, all
orders may be cancelled at any time after July 1, 2001, upon 12 months' written
notice. In the event of such a cancellation, the number of devices that may be
cancelled by AT&T each month may not exceed 8% of the number of devices billed
in the last full month prior to cancellation.

  Our arrangements with AT&T Business Network Services relate to multiple
carrier services: AT&T Frame Relay Plus Services, AT&T Inverse Multiplexing
Services, AT&T IP Enhanced Frame Relay Services and AT&T ATM Plus Services. Our
arrangements relating to Frame Relay Plus Services will terminate December 31,
2000, except that, following the termination date, we will continue to provide
services until the earlier of the expiration of the end user customer service
term or December 31, 2003. Our arrangements in support of Inverse Multiplexing
Services will terminate December 31, 1999. Our arrangements in support of IP
Enhanced Frame Relay Services will terminate April 4, 2000, except that,
following the termination date, we may continue to provide services until the
expiration of the end-user customer service term if elected by AT&T. The
arrangements in support of ATM Plus Services will terminate February 28, 2001,
except that, following the termination date, we will continue to provide
services until the earlier of the expiration of the end-user customer service
term or February 8, 2004.

  On December 9, 1998, AT&T announced that it was acquiring IBM's Global
Network business, which services the networking needs of global companies, mid-
sized businesses and individual Internet users. We are unable to predict what
impact, if any, this acquisition will have on our relationship with AT&T.

Sales and marketing

  We market our services directly to end users as well as to resellers.
Services sold to carrier resellers support the carriers' network operations or
are incorporated in services the carriers sell directly to end users. In fiscal
year 1999, 26% of network management service revenues was derived from direct
customers. Our strategy is to build our reseller channels and we expect that
these channels will represent an increasing percentage of our network
management revenues for the foreseeable future. Our resellers include AT&T, NEC
Business Network Solutions, e.spire Communications and Intermedia. All sales of
our services to date have been made in the U.S. However, we remotely manage
locations around the world for these U.S.-based customers.

  At June 30, 1999, we employed eleven people in sales and sales support. Each
sales person is assigned one or more reseller channels to support. Certain
sales individuals are also responsible for direct sales to end users of our
services. Reseller support by our sales organization includes assistance with
responses to requests for proposals, network design and proposal generation,
and participation in sales calls to potential customers. Our sales organization
also helps resellers define services and familiarize the reseller's sales
forces with our services and networking options. All of our sales and marketing
employees are based at our headquarters in Austin.

  At June 30, 1999, we employed five people in marketing who are responsible
for marketing communications, public relations and new service introductions.
Primary marketing communications include direct mail promotions, seminars and
our web site. Public relations activities include obtaining media coverage and
public recognition. Marketing activities related to new service introductions
include service definition, pricing, competitive analysis, service beta test
and general availability launches, identification of potential reseller
partners and service creation program management. The marketing group also
works closely with our larger reseller partners to define, develop and
implement embedded carrier services.

Software development

  The objective of our software development group, which consisted of 14 people
as of June 30, 1999, is to develop or integrate the tools we utilize to manage
networks and to develop software applications, such as ProWatch Exchange, which
become components of our services. While certain of our applications and tools
are proprietary, all are built using industry-standard protocols, tools and
development environments, including HyperText Markup Language, or HTML, Java,
Java Script, Microsoft Access, Oracle 8.x relational database software and
development tools, Remote Monitoring, or RMON, SNMP and Visual Basic.

Operations

  Our operations organization, comprised of 94 individuals as of June 30, 1999,
is responsible for delivery of our services to end users. By defining network
management tasks into sets of tightly defined services, we are able to deliver
functionality to our end users at cost effective prices. Our services generally
are provided using a team approach where each customer is assigned to a team of
customer engineers, with one member of the team being assigned primary customer
responsibility and each member providing back-up when the primary engineer is
not available.

  These customer engineer teams are supported by other groups within our
operations group. The first level of service delivery is our network management
center, which is staffed 24 hours per day, seven days per week with network
engineers and technicians who have a broad range of technical expertise. Our
network management center continuously monitors responses to polls to managed
devices and opens trouble tickets in response to network outages. The goal of
this group is to provide the end user with notice and a diagnosis within
fifteen minutes of a network failure. Upon isolation of the problem, the
appropriate service provider is dispatched to the end user's premises as
required to repair the outage. Network management center employees can
electronically enter trouble tickets into selected transport provider's systems
to enable faster resolution of carrier network issues.

  Other groups within operations include project implementation managers,
installation engineers, equipment staging and configuration personnel, and a
network and tools infrastructure group. By using specialized teams for defined
processes, we can utilize network engineers with a broad range of skills and
experience.

  Our approach to loss of the critical systems and management network
infrastructure utilized to manage customer networks is one of disaster-
avoidance backed up by selected disaster recovery. The network management
infrastructure is primarily Frame Relay-based providing the high availability
inherent in that technology. To minimize the potential loss of access to local
telecommunications infrastructure, we employ a SONET ring which is served from
two separate local exchange carrier serving offices. Our facility contains two
separate rooms with some redundant computing and networking equipment, each of
which is monitored 24 hours per day, seven days per week.

  We deliver our services utilizing a workforce with a wide range of skills,
from entry-level to highly trained networking professionals. We use a strict
operational methodology combined with proprietary software tools to leverage
our workforce. We believe that we can meet our resource requirements by hiring
experienced networking professionals and by recruiting and training recent
college graduates. Nonetheless, qualified IT professionals are in short supply
and we face significant competition for these professionals.

Competition

  Currently, we compete primarily with the internal network administration
organizations of actual or potential end users of our services. Many of these
end users have internal network support capabilities and could choose to
satisfy their needs through internal resources rather than through outside
service providers. We believe that the principal factors involved in competing
effectively with internal solutions include quality of service, price,
functionality and features, product reputation and quality of support.

                                       39
<PAGE>


  The remote network management service market is new, highly fragmented,
rapidly evolving and largely undefined. There are few substantial barriers to
entry, and we expect that we will face additional competition from existing
competitors and new market entrants in the future. Such competitors may have
significantly greater financial, technical and marketing resources and greater
name recognition than we have. We believe that the principal competitive
factors in this market include networking and security engineering expertise,
customer service, network and security capabilities, reliability and quality of
service, the ability to maintain and expand distribution channels, price, the
timing of introductions of new services, and conformity with industry
standards. While we believe that we currently are able to provide end users
with reliable network management and security services at prices that allow us
to compete favorably with respect to other service providers, there can be no
assurance that we will have the resources or expertise to compete successfully
in the future.

  We currently face competition from other remote network management companies
such as Comdisco; telecommunications providers such as AT&T, Sprint, and
MCI/WorldCom; network equipment vendors such as Bay/Nortel; and computer
systems vendors such as Digital Equipment Corporation and Hewlett Packard. With
respect to our security services, we currently face competition from computer
systems vendors such as IBM. We also face potential competition from IT
consulting firms, systems integrators, VARs, and local and regional network
services firms and other new entrants into our markets. Many of these current
and potential competitor companies have significantly greater financial,
technical and marketing resources and greater name recognition and generate
greater service revenue than we have. There can be no assurance that we will be
able to compete successfully against current or potential competitors. Our
failure to successfully compete would significantly damage our business.

  We also face potential competition from resellers with which we currently
partner, or could partner, to market and sell our services. These resellers
generally have substantially greater resources than we have and could directly
compete, rather than partner, with us. Such a decision by our resellers would
significantly damage our business.

  With respect to the sale of equipment and on-site equipment maintenance
services, we compete primarily with the equipment manufacturers and their
resellers.

Intellectual property rights

  We rely on a combination of patent, trademark, service mark and trade secret
laws and contractual restrictions to establish and protect certain proprietary
rights in technology underlying our services. We have applied for a patent with
the United States Patent Office. This patent relates to software technology
which allows us to poll, or communicate with, large numbers of routers or other
SNMP devices over multiple WANs. Although we currently have no patented
technology that would preclude or inhibit competitors from entering our market,
we intend to continue to evaluate the appropriateness of such protection and to
seek patent protection for our inventions when appropriate. There can be no
assurance that patents will issue from our currently pending or any future
applications, or that any patents that may be issued will be sufficient in
scope or strength to provide meaningful protection or any commercial advantage
to us. We have registered the name NetSolve, our logo and the names ProWatch
and ProWatch Secure as separate service marks in the United States and various
state trademark offices. We also have service mark registrations pending for
ProWatch for WANs, ProWatch for LANs and ProWatch Exchange. There can be no
assurance that such trademarks will be granted. We have not made any foreign
patent or trademark filings. We have entered into proprietary rights and
confidentiality agreements with our employees, and generally enter into
nondisclosure agreements with our suppliers, distributors and appropriate
customers in order to limit access to and disclosure of our proprietary
information.

  There can be no assurance that these contractual arrangements or the other
steps taken by us to protect our intellectual property will prove sufficient to
prevent infringement or misappropriation of our technology or to deter
independent third-party development of similar technologies. Any such
infringement or misappropriation, should it occur, could significantly damage
our business. Furthermore, litigation may be necessary to enforce our
intellectual property rights, to protect our trade secrets, to determine the
validity and scope of the

                                       40
<PAGE>


proprietary rights of others, or to defend against claims of infringement or
invalidity. Such litigation could result in substantial costs and diversion of
resources. We may be unable to protect our intellectual property, and we could
incur substantial costs defending our intellectual property from infringement
or claims of infringement.

  In June 1996, in connection with our registration of the service mark
NetSolve, GRC International, Inc. claimed that our use of the name NetSolve
infringed GRC's common law intellectual property rights. This claim was settled
by an agreement with GRC and GRC withdrew its opposition and consented to our
service mark registration. GRC retains the right to use the name NetSolve to
describe a particular software product, and we retain the full right to our
corporate name. We also agreed with GRC to refrain from using NetSolve as a
brand name to describe products and services. We believe that the limited joint
use of the name NetSolve by GRC will not have a material adverse effect on us.
With the exception of GRC, we have not, to date, been notified that our
services infringe the proprietary rights of third parties; however, there can
be no assurance that third parties will not claim infringement or
indemnification by us with respect to current or future services or products.
We expect that participants in our markets will be increasingly subject to
infringement claims as the number of services and competitors in our industry
segment grows. Any such claim, whether meritorious or not, could be time-
consuming, result in costly litigation, cause delays in product and service
installation and implementation, prevent us from using important technologies
or methods, subject us to substantial damages, or require us to enter into
royalty or licensing agreements. Such royalty or licensing agreements might not
be available on terms acceptable to us or at all. As a result, any such claim
could materially harm our business.

Employees

  As of June 30, 1999, we had 135 full-time employees, including 16 in sales
and marketing, 14 in development, 94 in operations and 11 in finance and
administration. Our success depends to a significant degree upon the continued
contributions of our executive management, network management and engineering
teams. Our future success will depend in large part upon our continued ability
to attract and retain highly skilled and qualified personnel.

  None of our employees is represented by a collective bargaining agreement. We
believe relations with our employees are good.

Facilities

  Our corporate headquarters are located in a leased facility in Austin, Texas.
In March 1998, we relocated all of our operations, including all employees and
the network management center, into our current facility, which covers
approximately 70,000 square feet. In connection with this move, we upgraded our
computing and network management infrastructure environment, adding an
uninterrupted power supply system backed up by a power generator to guard
against system failure and to provide emergency power in the event of an
outage. Our new facility allows us to maintain dual computer rooms with some
redundant equipment in order to provide safeguards in the event of a fire or
similar emergency.

  The lease for our offices expires in November 2008, including a five-year
option to renew. We believe that our current facilities are adequate to meet
our foreseeable requirements or that suitable additional or substitute space
will be available on commercially reasonable terms.

Litigation

  We are not currently a party to any material legal proceedings.

board of directors meeting attended by teleconference. Additionally, directors
are reimbursed for their reasonable expenses incurred in attending meetings of
the board of directors. Directors are eligible to participate in our 1988 Stock
Option Plan and Long-Term Incentive Compensation Plan.

Limitation of liability and indemnification matters

  Our certificate of incorporation limits the liability of directors to the
fullest extent permitted by Delaware law. Delaware law provides that a
corporation's certificate of incorporation may contain a provision eliminating
or limiting the personal liability of directors to the corporation or its
stockholders for monetary damages for breach of their fiduciary duties as
directors, except liability for (1) any breach of their duty of loyalty to the
corporation or its stockholders, (2) acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (3)
improper payments of dividends or improper stock repurchases or redemptions as
provided in Section 174 of the Delaware General Corporation Law, or (4) any
transaction from which the director derived an improper personal benefit.

  Our bylaws provide that we shall indemnify our directors, officers, employees
and agents to the fullest extent permitted by law. We believe that
indemnification under our bylaws covers at least negligence and gross
negligence on the part of indemnified parties.

  We have entered into agreements that indemnify our directors and executive
officers. These agreements, among other things, indemnify the directors and
executive officers for certain expenses, including attorneys' fees, and, in
some instances, judgments, fines and settlement amounts incurred by such
persons in any action or proceeding, including any action by us or on our
behalf, arising out of his or her service as a director or executive officer of
our company, any of our subsidiaries or any other company or enterprise to
which the person provides services at our request. We believe that these
provisions and agreements are desirable to attract and retain qualified
directors and executive officers.

  At present, there is no pending litigation or proceeding involving any of our
directors, officers, employees or agents in which indemnification will be
required or permitted. We are not aware of any threatened litigation or
proceeding that might result in a claim for such indemnification.

  All options were granted at their "fair market value" on the date of grant
and may be exercised at any time during the term of the option. Each option
vests over a four-year period with one fourth of the total amount vesting one
year from the date of grant and one-sixteenth of the total amount vesting in
each calendar quarter remaining. The unvested portion of any previously
exercised option is subject to our repurchase right upon termination of the
executive's employment. Under the terms of our Long-Term Incentive Compensation
Plan, the board of directors retains discretion, subject to certain limitations
provided for in the plan, to modify the terms of outstanding options. All
options were granted for a term of 10 years, subject to earlier termination in
certain events related to termination of employment. The exercise price for all
options may be paid in cash or shares of our common stock or a combination of
cash and shares.

  In connection with his commencing employment in July 1999, Mr. Budow was
granted an option to purchase 100,000 shares of our common stock under our
Long-Term Incentive Compensation Plan at an exercise price of $9.00 per share.

There was no public market for the common stock as of March 31, 1999.
Accordingly, the values of unexercised in-the-money options have been
calculated by determining the difference between an assumed public offering
price of $12.00 per share and the per share exercise prices of the options.

  No options were exercised by the Named Executive Officers during fiscal
  year 1999.

Long-term incentive compensation plan

  Our Long-Term Incentive Compensation Plan, or Long-Term Incentive Plan, was
adopted by the board of directors and approved by the stockholders in July
1997. It is administered by the compensation committee. The purpose of the
Long-Term Incentive Plan is to assist us in attracting, retaining and
motivating executive officers, key employees and directors and consultants who
are essential to our success through performance-related incentives linked to
long-range performance goals. Performance goals under the Long-Term Incentive
Plan may be based on individual performance of the particular employee and/or
include criteria such as absolute or relative levels of total stockholder
return, revenues, sales, net income or net worth of our company or any of our
subsidiaries, divisions, business units or other areas, all as the compensation
committee may determine.

  The Long-Term Incentive Plan is a comprehensive, stock-based incentive
compensation plan, providing for discretionary awards of incentive stock
options, nonqualified stock options, stock appreciation rights, restricted
stock, restricted stock units, performance shares, performance units, bonus
stock and other stock-based awards. All awards under the Long-Term Incentive
Plan are made in, or based on the value of, the common stock.

  Our full-time employees, directors, and consultants are eligible to
participate in, and receive awards under, the Long-Term Incentive Plan. The
selection of participants under the Long-Term Incentive Plan, as well as all
terms, conditions, performance criteria and restrictions applicable to each
award, are determined by the compensation committee in its sole discretion.

                                       46
<PAGE>


  The maximum number of shares of common stock for which awards may be granted
under the Long-Term Incentive Plan is 1,350,000 subject to adjustment in the
event of a merger, consolidation, reorganization, recapitalization, stock
dividend, stock split, or other similar event. Shares subject to previously
canceled, lapsed or forfeited awards, or awards paid in cash, may be reissued
under the Long-Term Incentive Plan. The shares to be issued under the Long-Term
Incentive Plan may consist of authorized but unissued shares, shares issued and
reacquired by us or shares purchased in the open market.

  We expect that awards made under the Long-Term Incentive Plan will be fully
deductible for federal income tax purposes. In this connection, if we become
subject to Section 162(m) of the Internal Revenue Code, which limits such
deductions for awards to certain covered participants, performance-based
compensation that can be provided to any covered participant in any year will
be limited to stock options for up to 100,000 shares. No other types of awards
may be made under the Long-Term Incentive Plan to covered participants.

  As of June 30, 1999, options covering an aggregate of 980,636 shares of
common stock had been granted under the Long-Term Incentive Plan at exercise
prices ranging from $2.80 to $9.00. Each of these options has a term of ten
years and may be exercised at any time during such term. The exercise price may
be paid in cash or shares of common stock already held by the exercising
participant, or a combination of cash and shares. Each option vests over a
four-year period with one-fourth of the total amount vesting one year from the
date of grant and one-sixteenth of the total amount vesting in each subsequent
calendar quarter. The unvested portion of any exercised options are subject to
our repurchase right upon termination of employment.

  The Long-Term Incentive Plan may be amended, modified, suspended or
terminated by the board of directors at any time. No amendment will be
effective prior to approval of the stockholders to the extent such approval is
necessary to comply with any legal requirement. If not earlier terminated, the
Long-Term Incentive Plan will terminate on December 31, 2006.

  Stock options. The Long-Term Incentive Plan authorizes (1) the grant of
options to purchase common stock intended to qualify as incentive stock options
under Section 422(b) of the Internal Revenue Code, or incentive options, and
(2) the grant of options that do not so qualify, or nonqualified options. The
number of shares and other terms of each grant are determined by the
compensation committee. The exercise price of incentive options granted under
the Long-Term Incentive Plan must be at least equal to the fair market value of
the common stock on the date of grant. The exercise price of incentive options
granted to an optionee who owns stock possessing more than 10% of the voting
power of our outstanding capital stock must equal at least 110% of the fair
market value of the common stock on the date of grant. The exercise price of
non-qualified options granted under the Long-Term Incentive Plan must not be
less than 50% of the fair market value of the common stock on the grant date.
Incentive options may be granted under the Long-Term Incentive Plan to
employees, including officers and directors who are also employees. Non-
qualified options may be granted under the Long-Term Incentive Plan to our
employees, officers, consultants and directors, whether or not they are our
employees. The exercise price for options granted under the Long-Term Incentive
Plan may be paid in cash or with shares of common stock. Options granted under
the Long-Term Incentive Plan may remain outstanding for no more than ten years.

  Stock appreciation rights. Stock appreciation rights, or SARs, entitle the
participant to receive, upon exercise of the SAR, cash or, at the election of
the administrator, shares of common stock or a combination thereof, in an
amount equal to the difference between the SAR exercise price and the fair
market value of the shares of common stock subject to the SAR. SARs may be
granted to participants under the Long-Term Incentive Plan on a freestanding
basis or in tandem with a stock option. The exercise price of SARs will not be
less than 100% of the fair market value of the common stock on the date of
grant. SARs granted under the Long-Term Incentive Plan will not be exercisable
until at least six months following the date of grant and no later than ten
years thereafter. Incentive options and SARs may not be transferred other than
by will or the laws of descent and distribution.

                                       47
<PAGE>


  Stock and stock unit awards. The Long-Term Incentive Plan also provides for
the granting of restricted stock, restricted stock units, performance shares
and performance stock units, bonus stock and other stock-based awards. The
number of shares or units and all terms and conditions, including the
restriction period, performance criteria and other restrictions and conditions
applicable to each such award, are determined by the compensation committee.
During the restriction period, participants may exercise full voting rights,
and are entitled to receive all dividends and other distributions paid, with
respect to restricted stock they have been granted, provided that stock
dividends, if any, remain subject to the same restrictions as the underlying
stock. Payment to the participant may be in shares of common stock or cash, or
a combination thereof, and in a lump sum or installments, all as determined by
the compensation committee. Shares of common stock may also be awarded to
participants under the Long-Term Incentive Plan as a bonus. Such shares may be
granted with or without restrictions. Shares awarded subject to performance
criteria or other restrictions which are not satisfied, are forfeited and must
be returned to us. In addition to the foregoing types of awards, the Long-Term
Incentive Plan permits the compensation committee to grant any other stock
based award as the administrator may determine. Such stock based awards may be
in the form of common stock or other securities, the value of which is based,
in whole or in part, on the value of common stock on the award date.

  Acceleration of vesting upon change in control. In the event of a change in
control of our company, all outstanding stock options and SARs shall
immediately become fully vested, and all restrictions and performance criteria
relating to all outstanding awards shall be deemed to have been fully
satisfied, unless the transaction or event constituting the change in control
was approved in advance by a majority of the board of directors. Under the
terms of the Long-Term Incentive Plan, a change in control shall be deemed to
have occurred if: (1) any person becomes the beneficial owner of 20% or more of
our voting securities; (2) we are involved in a merger, acquisition or similar
transaction pursuant to which our directors immediately before the transaction
cease to constitute a majority of our directors after the transaction; or (3)
we are involved in a transaction pursuant to which we are not the surviving
corporation, our common stock is exchanged for, or converted into securities of
another entity, we become a subsidiary of another entity, or 50% or more of our
aggregate assets or earning powers are sold to another entity.

1988 stock option plan

  Our 1988 Stock Option Plan, or 1988 Option Plan, was adopted by our board of
directors and approved by our stockholders in November 1988. The principal
purpose of the 1988 Option Plan is to advance the interests of our company and
our stockholders by enabling us to attract qualified management and other key
personnel and encourage selected directors, officers, key employees and
consultants to acquire and retain a proprietary interest in our company through
the ownership of our common stock. A total of 1,636,395 shares of common stock
has been reserved for issuance under the 1988 Option Plan.

  The 1988 Option Plan provides for the granting of incentive options to
employees, including officers and directors, and for the granting of
nonqualified options to employees and consultants, including nonemployee
directors, of nonqualified stock options. To the extent an optionee would have
the right in any calendar year to exercise for the first time one or more
incentive options for shares having an aggregate fair market value (under all
of our plans and determined for each share as of the date the option to
purchase the shares was granted) in excess of $100,000, any such excess options
shall be treated as nonqualified options.

  As of June 30, 1999, there were options outstanding under the 1988 Option
Plan for 1,636,395 shares of common stock. As of such date, a total of 863,442
shares had been purchased pursuant to option exercises and we had repurchased
6,600 unvested shares pursuant to the provisions of the 1988 Option Plan. No
incentive options were allowed to be granted under the 1988 Option Plan after
November 20, 1998.

  The 1988 Option Plan may be administered by the board of directors or a
committee of the board. The 1988 Option Plan is currently administered by the
compensation committee. The 1988 Option Plan administrator determines the terms
of options granted under the 1988 Option Plan, including the number of

                                       48
<PAGE>


shares subject to the option, exercise price, term and exercisability. The
exercise price of each incentive option granted under the 1988 Option Plan must
be at least equal to the fair market value of common stock on the date of
grant. The exercise price of any incentive option granted to an optionee who
owns stock representing more than 10% of the total combined voting power of all
classes of outstanding capital stock of our company or any parent or subsidiary
corporation of our company must equal at least 110% of the fair market value of
common stock on the date of grant. Payment of the exercise price may be made in
cash or by delivery of previously owned shares of common stock, or partly in
cash and partly in common stock.

  The 1988 Option Plan administrator determines the term of options, which may
not exceed ten years. No option may be transferred by an optionee other than by
will or the laws of descent or distribution. Each option may be exercised
during the lifetime of an optionee only by such optionee. The 1988 Option Plan
administrator determines when options become exercisable. Options granted under
the 1988 Option Plan are generally exercisable at any time, but are subject to
a four-year vesting schedule with one-fourth of the stock vesting one year from
the date of grant and one-sixteenth of the stock underlying the option vesting
in each subsequent calendar quarter. The unvested portion of exercised options
may be repurchased by us at the original exercise price upon termination of
employment.

  We have the authority to amend or terminate the 1988 Option Plan, except that
we may not increase the aggregate number of shares which may be issued under
options granted pursuant to the 1988 Option Plan, and we may not take any
action not expressly provided for in the 1988 Option Plan, in derogation of the
vested rights of any optionee under an option previously granted thereunder.

401(k) retirement plan

  Effective December 1, 1988, we established a 401(k) defined contribution
retirement plan, or Retirement Plan, covering all employees who are at least 21
years of age and have satisfied certain service eligibility requirements.
Effective February 1, 1997, the Retirement Plan was amended to eliminate any
service eligibility requirements so that employees who otherwise met the
eligibility criteria could commence participation upon being hired by us. The
Retirement Plan provides for voluntary employee contributions in amounts
determined by the employees, subject to a maximum limit allowed by Internal
Revenue Service guidelines ($10,000 for 1999). We may contribute such amounts
to the accounts of participants in the Retirement Plan as determined by the
board of directors, subject to certain legal requirements. To date, we have not
made any contribution to the Retirement Plan, and we do not anticipate making
any contribution to the Retirement Plan in the foreseeable future.

Bonus plan

  In July 1998, we adopted a bonus plan pursuant to which selected employees
are eligible to receive cash bonuses on a quarterly basis beginning with the
quarter ended September 30, 1998 if, during such quarter, we meet certain
financial performance objectives established from time to time by us. We may
amend or terminate the bonus plan at any time.

                     TRANSACTIONS WITH RELATED PARTIES

  Venture capital firms affiliated with Messrs. Gullard, Adams, Kramlich,
McCarthy and Wolfe, each of whom is a member of our board of directors, have
certain rights with respect to the registration of 604,541, 2,257,089,
3,182,734, 875,000, and 300,589 shares, respectively, of common stock they may
hold under the Securities Act. Under these rights, which are held by all
venture capital firms that participated in our financings, holders may require
us to register their shares and may include their shares in registration
statements filed by us.

  We have entered into indemnification agreements with our executive officers
and directors. Among other terms, under these agreements, we would agree to:

  . indemnify, to the fullest extent allowed by Delaware law, these
    officers and directors against certain liabilities related to their
    service or status as officers or directors; and

  . in any proceeding in which they could be indemnified, advance to
    these officers and directors the expenses they incur in those
    proceedings.

We intend to execute similar indemnification agreements with our future
directors and executive officers.

  As a matter of policy, all future transactions between us and any of our
directors or executive officers will be subject to approval by a majority of
the independent and disinterested members of the board of directors and will be
in connection with bona fide purposes of our company.

                       PRINCIPAL AND SELLING STOCKHOLDERS

  The following table sets forth information known to us with respect to the
beneficial ownership of our common stock as of June 30, 1999, and as adjusted

all of our current directors and executive officers as a group; (4) each person
we know to own beneficially more than five percent of the outstanding shares of

each stockholder identified in the table possesses sole voting and investment
power with respect to all shares of common stock shown as beneficially owned by
such stockholder. The number of shares beneficially owned by a person includes
shares of our common stock subject to options and warrants held by that person
that are currently exercisable within 60 days of June 30, 1999. Such shares
issuable pursuant to such options and warrants are deemed outstanding for
computing the percentage ownership of the person holding such options and
warrants but are not deemed outstanding for the purposes of computing the
percentage ownership of any other person. For purposes of this table, the
number of shares of common stock outstanding prior to the offering is deemed to
be 9,878,516, consisting of 3,483,789 shares of common stock outstanding on
June 30, 1999 and an additional 6,394,727 shares issuable upon conversion of
our preferred stock. For purposes of calculating the percentage beneficially
owned by any person, shares of our common stock issuable to such person upon
the exercise of any options exercisable within 60 days of June 30, 1999 are
also assumed to be outstanding. The number of shares of common stock deemed
outstanding after this offering includes the additional 3,500,000 shares being
offered by us hereby, and assumes no exercise of the underwriters' over-
allotment option.

                          DESCRIPTION OF CAPITAL STOCK

  Our authorized capital stock consists of 25,000,000 shares of common stock,
$0.01 par value per share, and 7,500,000 shares of undesignated preferred
stock, $0.10 par value per share.

Common stock

  As of June 30, 1999, we had 139 stockholders that owned a total of 9,878,516
shares of common stock, including shares issuable upon conversion of all
outstanding preferred stock. Options to purchase an aggregate of 2,584,411
shares of our common stock and warrants to purchase an aggregate of 107,500
shares of our common stock were also outstanding. There will be 13,378,516
shares of our common stock outstanding after this offering (assuming no
exercise of the underwriters' over-allotment option, and no exercise of
outstanding warrants or options after June 30, 1999) after giving effect to the
sale of the shares of common stock offered in this offering.

  Each share of our common stock is allowed one vote on all matters submitted
to a vote of the stockholders. Subject to preferences that may be applicable to
the holders of outstanding preferred stock issued in the future, if any,
holders of common stock are entitled to receive dividends as may be declared by
our board of directors. If we liquidate or dissolve, subject to the rights of
the holders of outstanding shares of preferred stock issued in the future, if
any, the holders of our common stock shall receive a share in all assets
remaining after liabilities are paid and preferential rights of any outstanding
preferred stock are satisfied. The common stock has no preemptive or conversion
rights or other subscription rights. All shares of our common stock are, and
those to be issued in this offering will be, fully paid and non-assessable.

Preferred stock

  Each share of our preferred stock outstanding as of June 30, 1999 will be
converted into one share of our common stock and automatically retired upon the
closing of this offering. Thereafter, our board of directors is authorized to
issue up to 7,500,000 shares of preferred stock. Our board of directors may
designate one or more series of preferred stock and may assign differing
rights, preferences, privileges and restrictions, including dividend rights,
dividend rates, conversion rights, voting rights, terms of redemption,
redemption prices, liquidation preferences and the number of shares
constituting any series or the designation of such series, without further
stockholder vote or action.

  If we issue preferred stock, this may delay, defer or prevent a change in
control of our company without further stockholder action. The issuance of
preferred stock with voting and conversion rights may adversely affect the
voting power of the holders of our common stock. In certain circumstances, the
market price of our common stock may decrease as a result. As of the closing of
this offering, no shares of preferred stock will be outstanding and we
currently have no plans to issue any shares of preferred stock.

Warrants

  As of June 30, 1999, we had outstanding exercisable warrants to purchase
107,500 shares of our common stock with a weighted average exercise price of
$2.01 per share. These warrants will expire between 1999 and 2001.

Registration rights

  Following this offering, the holders of 9,378,511 shares of common stock will
be entitled to certain rights relating to the registration of such shares under
state and federal securities laws. These rights, which are assignable, are
outlined in an agreement between us and the holders of these shares of common
stock. The holders of at least 30% of these shares may generally require that
we register their shares for public resale. If we register any of our common
stock, either for our own

                                       53
<PAGE>


account or for the account of other security holders, the holders of these
shares are entitled to include their shares in such registration, subject to
the ability of the underwriters to limit the number of shares included in such
offering. Holders of at least 20% of these shares may also require us, not more
than one time in any 12-month period, to register all or a portion of their
shares on Form S-3, when use of such form becomes available, provided that,
among other limitations, the proposed aggregate selling price (net of any
underwriters' discounts or commissions) is at least $1,000,000. These
registration rights terminate at the earlier of: (a) such time as the holder
may, within a three-month period, offer and sell all of his shares pursuant to
Rule 144 under the Securities Act without any adverse effect on the price at
which such shares may be sold, such determination as to such adverse effect to
be made by such holder acting in good faith; or (b) 48 months from the closing
of this offering.

Delaware law and charter provisions

  Provisions of Delaware law and our certificate of incorporation could
complicate our acquisition by means of a tender offer, a proxy contest or
otherwise. In addition, it might be difficult to remove incumbent officers and
directors. These provisions are expected to discourage certain types of
coercive takeover practices and inadequate takeover bids and to encourage
negotiation between our management and those persons seeking control. We
believe it is more advantageous to protect our potential ability to negotiate,
rather than discourage, unfriendly or unsolicited third parties attempting to
acquire or restructure us. Among other things, negotiating such proposals could
result in an improvement of their terms.

  We are subject to the provisions of Section 203 of the Delaware General
Corporation Law. In general, Section 203 prohibits a publicly held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date that the person became
an interested stockholder unless (with certain exceptions) the business
combination or the transaction in which the person became an interested
stockholder is approved in a prescribed manner. Generally, a "business
combination" includes a merger, asset or stock sale, or other transaction
resulting in a financial benefit to the stockholder. Generally, an "interested
stockholder" is a person who, together with affiliates and associates, owns (or
within three years prior, did own) 15% or more of the corporation's voting
stock. This provision may delay, defer or prevent a change in control of our
company without the stockholders taking further action.

  It is more difficult for our existing stockholders to replace the board of
directors as well as for another party to obtain control of our company by
replacing our board of directors because cumulative voting is eliminated. Our
board of directors has the power to retain and discharge officers, making it
more difficult for existing stockholders or another party to change the
management.

  The foregoing provisions could have the effect of making it more difficult
for a third party to effect a change in the control of our board of directors.
In addition, these provisions could make it more difficult for a third party to
acquire, or discourage a third party from attempting to acquire, a majority of
our outstanding voting stock.

Transfer agent and registrar

  The transfer agent and registrar for the common stock is American Stock
Transfer & Trust Company.

                      SHARES ELIGIBLE FOR FUTURE SALE

  Before this offering, there has been no public market for our common stock,
and no prediction can be made as to the effect, if any, that future sales of
common stock or the availability of common stock for sale in the public market
will have on prevailing market prices of our common stock. Furthermore, because
only a limited number of shares will be available for sale for 180 days after
this offering as a result of resale restrictions (as described below), sales of
substantial amounts of our common stock in the public market after these
restrictions lapse could lower the prevailing market price and our ability to
raise equity capital in the future.

  Upon the closing of this offering, we will have outstanding an aggregate of
13,378,516 shares of our common stock (assuming no exercise of the
underwriters' over-allotment option and no exercise of warrants or options to
purchase common stock outstanding as of June 30, 1999). Of these shares, the
3,700,000 shares sold in this offering will be freely tradeable without
restriction or further registration under the Securities Act, except that
shares purchased by an existing "affiliate" of ours as that term is defined in
Rule 144 under the Securities Act may be sold only in compliance with the
limitations described below. The remaining 9,878,516 shares of common stock
held by existing stockholders are "restricted securities" as that term is
defined in Rule 144 under the Securities Act.

  Subject to these lock-up agreements, the shares of common stock outstanding
upon the closing of the offering will be available for sale in the public
market as follows:

<TABLE>
<CAPTION>
   Number of
    Shares   Date

   3,700,000 After the date of this prospectus, freely tradeable shares sold in

   9,283,678 After 180 days from the date of this prospectus (subject in some
             cases to volume limitations and other restrictions of Rule 144).
     229,934 At various times after 180 days from the date of this prospectus,
             upon expiration of applicable holding periods under Rule 144
             (subject in some cases to volume limitations and other
             restrictions of Rule 144).
</TABLE>

  In addition, as of June 30, 1999, there were outstanding 2,584,411 options
and 107,500 warrants to purchase shares of common stock. Of such options, held
primarily by affiliates, 2,035,100 will be subject to 180-day lock-up
agreements. After 180 days from the date of this prospectus 1,470,882 of such
options will be vested and exercisable. All of such warrants are exercisable
and will be eligible for sale, subject to the restrictions of Rule 144.

  Lock-up agreements. All of our officers and directors and certain
stockholders and optionholders have entered into lock-up agreements with the
underwriters under which they agree not to transfer or dispose of, directly or
indirectly, any shares of our common stock or any securities convertible into,
or exercisable or exchangeable for shares of our common stock owned by them
(other than shares purchased in the public market), for a period of 180 days
after the date of this prospectus. Transfers or dispositions can be made
sooner: (a) with the prior written consent of BancBoston Robertson Stephens, in
the case of certain transfers to affiliates who sign identical lock-up
agreements or (b) if the transfer is a bona fide gift and the donee signs an
identical lock-up agreement. BancBoston Robertson Stephens may, in its sole
discretion and at any time without notice, release all or any portion of the
securities subject to such restrictions; however, BancBoston Robertson Stephens
currently has no plans to release any portion of the securities subject to
these lock-up agreements.

  Rule 144. In general, under Rule 144 as currently in effect, beginning 90
days after the date of this prospectus, a person (or persons whose shares are
aggregated) who has beneficially owned restricted shares for at least one year
(including the holding period of certain prior owners except an affiliate) is
entitled to sell within any 90-day period a number of shares that does not
exceed the greater of: (a) 1% of the number of

                                       55
<PAGE>


shares of our common stock then outstanding (which is expected to be
approximately 133,785 shares immediately after this offering); or (b) the
average weekly trading volume of our common stock on the Nasdaq National Market
during the four calendar weeks preceding the filing of a notice on Form 144
with respect to that sale. Sales under Rule 144 are also subject to certain
manner-of-sale provisions, notice requirements and the availability of current
public information about us.

  Rule 144(k). Under Rule 144(k), a person who is not deemed to have been 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
(including the holding period of certain prior owners except an affiliate), is
entitled to sell those shares without complying with the manner for sale,
public information, volume limitation or notice provisions of Rule 144.
Therefore, unless otherwise restricted, "144(k) shares" may be sold immediately
upon the closing of this offering.

  Rule 701. In general, Rule 701 of the Securities Act may be relied upon with
respect to the resale of securities originally purchased from us by our
directors, officers, employees, consultants or advisors before the date of this
prospectus, in connection with written compensatory benefit plans or written
contracts relating to the compensation of such persons. In addition, Rule 701
will apply to the stock options granted by us before the date of this
prospectus, along with the shares acquired upon exercise of such options
(including exercises after the date of this offering). Shares issued under Rule
701 are restricted securities and, subject to the contractual restrictions
described above, may be sold beginning 90 days after the date of this
prospectus by: (1) persons other than affiliates, subject only to the manner-
of-sale provisions of Rule 144 and (2) affiliates without compliance with
certain restrictions contained in Rule 144, including the one-year minimum
holding period.

  Stock plans. Approximately 90 days after this offering, we intend to file a
registration statement under the Securities Act covering approximately
3,850,000 shares of common stock subject to outstanding options or reserved for
issuance under our Long-Term Incentive Plan and 1988 Option Plan. Shares
registered under this registration statement, and not subject to a 180-day
lock-up agreement will, subject to Rule 144 volume limitations applicable to
affiliates, be available for sale in the open market.

  Registration rights. After this offering, the holders of approximately
9,378,511 shares or their transferees will be entitled to certain rights with
respect to the registration of those shares under the Securities Act.
Approximately 9,199,614 of such shares will be subject to 180-day lock-up
agreements. Registration of such shares under the Securities Act would result
in such shares becoming freely tradeable without restriction under the
Securities Act (except for shares purchased by affiliates) immediately upon the
effectiveness of such registration.

  The representatives have advised us and the selling stockholders that the
underwriters propose to offer the shares of common stock to the public at the
public offering price set forth on the cover page of this prospectus and to
certain dealers at such price less a concession of not in excess of $   per
share, of which $   may be reallowed to other dealers. After this offering, the
public offering price, concession and reallowance to dealers may be reduced by
the representatives. No such reduction shall change the amount of proceeds to
be received by us and the selling stockholders as set forth on the cover page
of this prospectus.

  We have granted to the underwriters an option, exercisable during the 30-day
period after the date of this prospectus, to purchase up to 555,000 additional
shares of common stock at the same price per share as we and the selling
stockholders will receive for the 3,700,000 shares that the underwriters have
agreed to purchase. To the extent that the underwriters exercise such option,
each of the underwriters will have a firm commitment to purchase approximately
the same percentage of such additional shares that the number of shares of
common stock to be purchased by it shown in the above table represents as a
percentage of the 3,700,000 shares offered hereby. If purchased, such
additional shares will be sold by the underwriters on the same terms as those
on which the 3,700,000 shares are being sold. We and such selling stockholders
will be obligated, pursuant to the option, to sell shares to the extent the
option is exercised. The underwriters may exercise such option only to cover
over-allotments made in connection with the sale of the shares of common stock
offered hereby.

  The underwriting agreement contains covenants of indemnity among the
underwriters, us and the selling stockholders against certain civil
liabilities, including liabilities under the Securities Act and liabilities
arising from breaches of representation and warranties contained in the
underwriting agreement.

  All of our officers and directors and certain stockholders and optionholders
have entered into lock-up agreements with the underwriters under which they
agree not to transfer or dispose of, directly or indirectly, any shares of our
common stock or any securities convertible into, or exercisable or exchangeable
for shares of our common stock owned by them (other than shares purchased in
the public market), for a period of 180 days after the date of this prospectus.
Transfers or dispositions can be made sooner: (a) with the prior written
consent of BancBoston Robertson Stephens, in the case of certain transfers to
affiliates who sign identical lock-up agreements or (b) if the transfer is a
bona fide gift and the donee signs an identical lock-up agreement. BancBoston
Robertson Stephens may, in its sole discretion and at any time without notice,
release all or any portion of the securities subject to such restrictions;
however, BancBoston Robertson Stephens currently has no

                                       57
<PAGE>


plans to release any portion of the securities subject to these lock-up
agreements. In addition, we have agreed that during the 180-day lock-up period
we will not, without the prior written consent of BancBoston Robertson
Stephens, (1) consent to the disposition of any shares held by stockholders
subject to lock-up agreements prior to the expiration of the 180-day lock-up
period or (2) issue, sell, contract to sell, or otherwise dispose of, any
shares of common stock, any options or warrants to purchase any shares of
common stock or any securities convertible into, exercisable for or
exchangeable for shares of common stock other than our sale of shares in this
offering, the issuance of common stock upon the exercise of outstanding
options, and our issuance of options and shares under existing stock option and
incentive plans.

  The underwriters do not intend to confirm sales to any accounts over which
they exercise discretionary authority.

  Prior to this offering, there has been no public market for our common stock.
Consequently, the public offering price for the common stock offered by this
prospectus will be determined through negotiations among us, the selling
stockholders and the representatives. Among the factors to be considered in
such negotiations are prevailing market conditions, certain of our financial
information, market valuations of other companies that we and the
representatives believe to be comparable to our company, estimates of our
business potential, the present state of our development and other factors
deemed relevant.

  Thomas Weisel Partners, one of the representatives of the underwriters, was
organized and registered as a broker-dealer in December 1998. Since December
1998, Thomas Weisel Partners has been named as a lead or co-manager on 45 filed
public offerings of equity securities, of which 27 have been completed, and has
acted as a syndicate member in an additional 19 public offerings of equity
securities. Thomas Weisel Partners does not have any material relationship with
us or any of our officers, directors or other controlling persons, except with
respect to its contractual relationship with us pursuant to the underwriting
agreement to be entered into in connection with this offering.

  Stabilization. The representatives have advised us that, pursuant to
Regulation M under the Securities Act, certain persons participating in this
offering may engage in transactions, including stabilizing bids, syndicate
covering transactions or the imposition of penalty bids, that may have the
effect of stabilizing or maintaining the market price of the common stock at a
level above that which might otherwise prevail in the open market. A
"stabilizing bid" is a bid for or the purchase of common stock on behalf of the
underwriters for the purpose of fixing or maintaining the price of the common
stock. A "syndicate covering transaction" is the bid for or the purchase of
common stock on behalf of the underwriters to reduce a short position incurred
by the underwriters in connection with this offering. A "penalty bid" is an
arrangement permitting the representatives to reclaim the selling concession
otherwise accruing to an underwriter or syndicate member in connection with
this offering if the common stock originally sold by such underwriter or
syndicate member is purchased by the representatives in a syndicate covering
transaction and has therefore not been effectively placed by such underwriter
or syndicate member. The representatives have advised us that such transactions
may be effected on the Nasdaq National Market or otherwise and, if commenced,
may be discontinued at any time.

                                 LEGAL MATTERS

  The validity of the shares offered hereby will be passed upon for us by
Worsham, Forsythe & Wooldridge, L.L.P., Dallas, Texas. Legal matters will be
passed upon for the underwriters by Foley, Hoag & Eliot LLP, Boston,
Massachusetts.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

Board of Directors and Stockholders
NetSolve, Incorporated

  We have audited the accompanying consolidated balance sheets of NetSolve,
Incorporated as of March 31, 1998 and 1999, and the related consolidated
statements of operations, stockholders' equity (deficit) and cash flows for
each of the three years in the period 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 consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of NetSolve, Incorporated, at March 31, 1998 and 1999, and the consolidated
results of their operations and their cash flows for each of the three years in
the period ended March 31, 1999, in conformity with generally accepted
accounting principles.

Company's own nationwide network, which utilized network transmission
facilities leased by the Company from major carriers), as well as the resale of
a major carrier's Frame Relay service offering. The data transport services
business segment was discontinued in December 1996 (see Note 3).

2. Summary of Significant Accounting Policies

 Principles of Consolidation

  The consolidated financial statements include the accounts of NetSolve,
Incorporated and its wholly-owned subsidiaries, Specialized Network Services,
Inc. and SNS Credit Corporation. All significant intercompany accounts and
transactions have been eliminated in consolidation.

 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.

 Inventory

  Inventory consists of purchased finished goods held for sale to customers.
Inventory is stated at the lower of cost or market with cost determined on a
specific identification basis.

 Property and Equipment

  Property and equipment are recorded at historical cost. Maintenance and
repairs are charged to expense as incurred and betterments which increase the
value or extend the useful life of the equipment are capitalized.

  Depreciation is provided using the straight-line method over the estimated
useful lives of the related assets. The Company's assets are currently
depreciated over periods ranging from three to seven years. Leasehold
improvements are amortized over the life of the related lease or assets,
whichever is shorter. Amortization of assets recorded under capital leases is
included in depreciation expense.

  In accordance with Statement of Financial Accounting Standards (SFAS) 121,
the Company reviews its long-lived assets for impairment. Based on the results
of a periodic review of equipment for obsolescence the Company recorded a
$77,000 charge to cost of equipment and other revenues in fiscal 1998.

 Income Taxes

  The Company accounts for income taxes in accordance with SFAS 109, Accounting
for Income Taxes. This statement prescribes the use of the liability method
whereby deferred tax asset and liability account balances 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.

 Stock-Based Compensation

  The Company has elected to follow Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees ("APB 25") and related interpretations
in accounting for its employee stock options because, as discussed in Note 5,
the alternative fair value accounting provided for under SFAS 123, Accounting
for Stock-Based Compensation, requires use of option valuation models that were
not developed for use in valuing employee stock options. Under APB 25, no
compensation expense has been recognized because all of the Company's options
were granted at prices equal to or in excess of the fair market value of the
underlying stock at the date of grant as determined by the Board of Directors.

 Earnings Per Share

  The Company's earnings per share data are presented in accordance with SFAS
128, Earnings Per Share. Basic income (loss) per share is computed using the
weighted average number of common shares outstanding. Diluted income (loss) per
share is computed using the weighted average number of common shares
outstanding adjusted for the incremental shares attributed to outstanding
securities with the ability to purchase or convert into common stock. The
treasury stock method, using the average price of the Company's common stock
for the period, is applied to determine dilution from options and warrants. The
if-converted method is used for convertible securities. Potentially dilutive
common stock options and warrants that were excluded from the calculation of
diluted income (loss) per share because their effect is antidilutive totaled
1,317,224, 1,265,861 and 1,648,841 in 1997, 1998 and 1999, respectively, and
1,687,424 for the three months ended June 30, 1998. For 1997, 1998, 1999 and
the three months ended June 30, 1998 and 1999, 6,394,727 shares of convertible
preferred stock were excluded from the calculation of diluted income (loss) per
share as their effect is also antidilutive.

  A reconciliation of the numerators and denominators used in computing per
share net income (loss) from continuing operations is as follows:

 Revenue Recognition

  Network management services revenues are recognized in the period services
are provided by NetSolve, whether sold directly or through resellers, based
upon rates established by contract net of any availability credits. The typical
contract terms are from 24 to 36 months and provide for one-time services,
consisting primarily of project implementation services at a fixed fee per
customer site or device, as well as recurring services which are provided at a
fixed monthly fee per customer site or device over the life of the contract.
Revenues for project implementation services are recognized upon completion of
the implementation of the site, and recurring revenues are recognized on a
monthly basis as the services are performed. Equipment revenues are recognized
in the period the equipment is shipped to the customer. Equipment revenues from
assets leased by the Company's lease financing subsidiary are recognized upon
the sale of the equipment and the related lease to a third party lessor on a
non-recourse basis following installation of the equipment. Other revenues,
which consist primarily of equipment maintenance services, are recognized in
the period services are provided. The Company's remote network management
services for WANs typically include a guarantee providing end-to-end network
availability for at least 99.5% of the time in any given month. In the event
the guaranteed availability is not achieved, the Company generally is obligated
to refund its WAN management fees for that month. The Company provides a
reserve based on the estimated costs of these refunds.

 Advertising Costs

  The Company expenses advertising costs as incurred. Advertising expense for
the years ended March 31, 1997 and 1998 and 1999 was approximately $242,000,
$370,000 and $419,000 respectively.

 Research and Development

  Expenditures for research and development are expensed as incurred.

 Cash, Cash Equivalents and Certificates of Deposit

  The Company considers all investments purchased with an original maturity of
three months or less to be cash equivalents. Certificates of deposit consist of
investments that mature within one year.

 Concentrations of Credit Risk

  Financial instruments which potentially expose the Company to concentrations
of credit risk as defined by SFAS 105, Disclosure of Information about
Financial Instruments with Off-Balance-Sheet Risk and Financial Instruments
with Concentrations of Credit Risk, consist primarily of cash and cash
equivalents (including restricted cash), investments and accounts receivable.
The Company places its temporary cash investments with FDIC-insured financial
institutions in accounts which, at times, may exceed federally insured limits.
The Company has not experienced any losses in such accounts. The Company
believes it is not exposed to any significant credit risk on cash and cash
equivalents. The Company performs credit evaluations of its customers'
financial condition when management deems it appropriate and generally requires
no collateral from its customers. Concentrations of credit risk with respect to
accounts receivable are generally limited due to the credit-worthiness of the
customers. Accounts receivable from AT&T represented 47% and 69% of the
outstanding accounts receivable balance at March 31, 1998 and 1999,
respectively.

</TABLE>

 Concentrations of Revenues

  Revenues from AT&T amounted to 30%, 52%, 59% and 69% of the Company's net
revenues for the years ended March 31, 1997, 1998, 1999 and the three months
ended June 30, 1999, respectively. The Company currently is providing multiple
services to AT&T under a single agreement with separate amendments for each
service. Management believes its relationship with this customer is good and
that the contract and the related amendments, which expire at various dates
from December 1999 to December 2001, will be renewed or replaced. No other
customer accounted for greater than 10% of revenue in fiscal year 1997, 1998,
1999 and the three months ended June 30, 1999.

 Comprehensive Income (Loss)

  In June 1997, the Financial Accounting Standards Board issued SFAS 130,
Reporting Comprehensive Income. The Company adopted SFAS 130 in the year ended
March 31, 1999. There was no impact to the Company as a result of the adoption
of SFAS 130, as there were no significant differences between net income (loss)
and comprehensive income (loss) for all periods presented.

 Segments

  In June 1997, the Financial Accounting Standards Board issued SFAS 131,
Disclosures about Segments of an Enterprise and Related Information. The
Company adopted SFAS 131 in the year ended March 31, 1999. The implementation
of this standard had no impact on its financial disclosures as the Company had
no reportable operating segments.

 Unaudited Pro Forma Information

  The Company's historical capital structure is not indicative of its
prospective structure due to the automatic conversion of all shares of
redeemable convertible preferred stock into common stock concurrent with the
closing of the Company's anticipated initial public offering. Therefore, the
pro forma calculations reflect the conversion of all outstanding shares of
redeemable convertible preferred stock into 6,394,727 shares of common stock
upon the Company's initial public offering using the if-converted method.

 Unaudited Interim Results

  The accompanying consolidated balance sheet as of June 30, 1999, the
consolidated statements of operations and cash flows for the three months ended
June 30, 1998 and 1999 and the consolidated statements of stockholders' equity
(deficit) for the three months ended June 30, 1999 are unaudited. In the
opinion of management, the statements have been prepared on the same basis as
the audited consolidated financial statements and include all adjustments,
consisting only of normal recurring adjustments, necessary for the fair
statement of the results of the interim periods. Operating results for the
three months ended June 30, 1999 are not necessarily indicative of the results
that may be expected for the year ending March 31, 2000.

 Reclassifications

  Certain reclassifications have been made to prior period balances to conform
to the current period presentation.

3. Sale of Transport Business Segment

  In December 1996, the Company made a decision to discontinue its data
transport services business segment and closed a transaction with Intermedia
Communications Inc. of Florida ("Intermedia") for the sale of a portion of that
segment. The sale to Intermedia was closed on December 30, 1996 at a price of
$12,280,000 of which $2,000,000 was placed in an escrow account. The escrowed
funds were released to the Company in November 1997.

  As a part of this transaction, all customer and supplier contracts related to
a portion of the business segment were assigned to Intermedia, and the capital
equipment related to this portion of the business segment was sold to
Intermedia. The agreement for this sale contains a non-compete provision which
prohibits the Company from competing in the data transport business for five
years.

  In connection with this sale, the Company agreed to provide management
services to assist Intermedia in supporting the acquired customer base for a
period of 12 months. These services were provided through October 1997. The
Company recorded revenue of $500,000, $715,000, and $0 in fiscal years 1997,
1998 and 1999, respectively, with respect to these services.

  To complete the discontinuance of this business segment, the Company assigned
its rights and obligations to customer contracts for other transport services
resold by the Company, and its obligations under a supplier contract, effective
October 1, 1997 to NetPlus, Inc. The purchase price, which was initially
established at 25% of NetPlus' gross profit from these services (as defined in
the purchase agreement) for a period of three years beginning April 1, 1998 up
to a maximum of $600,000, was renegotiated to $100,000 which was received in
fiscal year 1999. Revenues in fiscal year 1998, prior to the assignment to
NetPlus in October 1997, totaled approximately $1,072,000, and related costs of
providing such services approximated $826,000. Revenues from this business
segment were $13,223,000 and $1,072,000 for the years ended March 31, 1997, and
1998, respectively.

  During the fiscal year ended March 31, 1998, upon conclusion of all remaining
activities of this business segment, the Company reversed unused accruals
totaling approximately $557,000 (including $250,000 which was provided to
absorb potential reductions in the purchase price if billings to the sold
customer base fell below levels set forth in the agreement with Intermedia).

4. Redeemable Convertible Preferred Stock

  The Company had issued and outstanding shares of redeemable convertible
preferred stock as follows:

<TABLE>

                                                   March 31, March 31, March 31,

                                                   --------- --------- ---------
   <S>                                             <C>       <C>       <C>
   Series A convertible preferred stock........... 3,944,184 3,944,184 3,944,184
   Series B convertible preferred stock........... 2,450,543 2,450,543 2,450,543
</TABLE>

  The Series A redeemable convertible preferred stock is redeemable at the
option of the Board of Directors of the Company. The redemption price for each
share of Series A redeemable convertible preferred stock is an amount equal to
the original issue price per share ($4.00), plus $.033 per share for each month
that has passed since the date of issuance (the "Premium"). The Series A
redeemable convertible preferred stock was issued during April through August
1991, resulting in a per share premium of $3.011 to $3.158 at March 31, 1999
and an aggregate redemption price of $28,102,000.

  The Series A redeemable convertible preferred stock is convertible into
shares of common stock of the Company at the option of the holder at any time
after the date of issuance and prior to the date of redemption. Generally, the
conversion price will be the lower of the original issue price of the Series A
redeemable convertible preferred stock ($4.00 per share) or the price per share
of any subsequent equity financing which is less than the original issue price
(there have been no such subsequent offerings through March 31, 1999). In
addition, all convertible preferred stock will be automatically converted into
common stock upon a public offering of the Company's common stock which results
in aggregate cash proceeds in excess of $10,000,000 and at an offering price of
at least $6.00 per share. The Company has reserved 3,944,184 shares of common
stock for issuance upon conversion of the Series A redeemable convertible
preferred stock.

  In the event of any liquidation, dissolution or winding up of the Company,
either voluntary or involuntary, holders of all the Series A redeemable
convertible preferred stock shall be entitled to receive an amount per share
equal to the sum of the original issue price plus the Premium prior and in
preference to any distribution of the Company's assets to holders of common
stock. In the event of a consolidation or merger in which the holders of all
series of convertible preferred stock hold less than 51% of the new entity,
such consolidation or merger shall, at the option of each holder, be deemed to
be a liquidation. If the assets of the Company are insufficient to satisfy the
full amount of liquidation preference, then the Company's assets will be
distributed among the holders of the Series A redeemable convertible preferred
stock pari passu with holders of any other series of redeemable convertible
preferred stock.

  Holders of Series A redeemable convertible preferred stock are entitled to
annual per share dividends of $0.40 when and as declared by the Company's Board
of Directors. Such dividends are not cumulative. Dividends on redeemable
convertible preferred stock are prior and in preference to any declaration or
payment of any dividend on the Company's common stock. Dividends must be
declared and paid on all series of redeemable convertible preferred stock if
declared or paid on any series of redeemable convertible preferred stock. No
dividends have been declared to date.

  The holders of all series of redeemable convertible preferred stock are
entitled to one vote for each share of common stock into which such redeemable
convertible preferred stock could then be converted.

  The Series A redeemable convertible preferred stock purchase agreement
contains various covenants, restrictions and provisions, including a
restriction on the payment of dividends on the Company's common stock other
than dividends payable solely in common stock of the Company. In addition, this
agreement

restricts the Company's ability to make loans or advances to, or investments in
securities and obligations of, other entities and provides restrictions as to
the repurchase of outstanding shares of capital stock except pursuant to the
terms of any shareholder agreements with employees of the Company or the
redemption of redeemable convertible preferred stock.

  The Series B redeemable convertible preferred stock has redemption and
conversion rights, liquidation preferences and voting rights identical to those
of the Series A redeemable convertible preferred stock. Additionally, the
Series B redeemable convertible preferred stock purchase agreement contains
covenants, restrictions and provisions similar to those described above in the
Series A redeemable convertible preferred stock purchase agreement. The Series
B redeemable convertible preferred stock has a per share premium of $2.382 to
$2.551 at March 31, 1999 and an aggregate redemption price of $16,044,000. The
Company has reserved 2,450,543 shares of common stock for issuance upon
conversion of the Series B redeemable convertible preferred stock.

5. Stockholders' Equity (Deficit)

 Stockholder Repurchase Rights

  The Company has entered into stockholder agreements with certain
stockholders, and with all employees and consultants who have received grants
of options pursuant to the Company's stock option plans. These agreements
generally grant the Company certain repurchase rights with respect to common
stock purchased by the stockholders. The percentage of shares subject to
repurchase generally decreases by 25% on the first anniversary of the granting
of a stock option and quarterly (at 6.25% per quarter) thereafter. The
Company's repurchase rights are exercisable upon termination of employment of
the employee or consultant. The agreements also provide the Company a right of
first refusal on the sale of any shares issued pursuant to the agreements. At
March 31, 1999, total outstanding options subject to repurchase rights were
942,638.

 Stock Option Plans

  In November 1988, the Company adopted a stock option plan providing for the
granting of options to purchase shares of the Company's common stock to key
employees, directors, officers and consultants as designated by the Company's
Board of Directors. As of March 31, 1999, an aggregate of 2,601,976 shares was
approved for issuance under the Plan. The Plan provides for the issuance of
both Incentive Stock Options ("ISOs") as well as options not qualifying as ISOs
within the meaning of the Internal Revenue Code of 1986, as amended. Under the
terms of the Plan, the option price per share of ISOs may not be less than 100%
of the fair market value of the Company's common stock per share at date of
grant. Options may not be granted with a term exceeding 10 years and are
immediately exercisable. Shares acquired pursuant to the exercise of options
are subject to certain vesting and repurchase requirements as set forth above.

  In July 1997, the Company adopted a long-term incentive compensation plan.
This plan is a comprehensive, stock-based incentive compensation plan,
providing for discretionary awards of incentive stock options within the
meaning of the Internal Revenue Code of 1986, as amended, nonqualified stock
options, stock appreciation rights, restricted stock, restricted stock units,
performance shares, performance units, bonus stock and other stock-based
awards. All awards will be made in, or based on the value of, the Company's
common stock. The plan will be administered by the Compensation Committee of

directors of, and consultants to, the Company will be eligible to participate
in, and receive awards under the plan. The maximum number of shares of common
stock for which awards may be granted under the plan is 1,350,000. The price
payable upon exercise of an option which is intended to constitute an incentive
stock option may not be less than 100% of the fair market value of the common
stock at the time of grant.

  The Company has also granted non-qualified options other than pursuant to the
above plans. Options granted totaled 3,250 shares representing grants to two
outside directors at exercise prices of $.80 and $1.20 per share. During fiscal
1999, 1,250 of these options were exercised.

  At March 31, 1999 the Company had reserved 3,148,723 shares of common stock
for issuance upon exercise of all options.

 Statement of Financial Accounting Standards No. 123

  Pro forma information regarding net income (loss) is required by SFAS 123,
and has been determined as if the Company had accounted for its stock options
under the fair value method of that Statement. The fair value for options
granted prior to the Company's initial filing on Form S-1 dated October 15,
1998 was estimated as of the date of grant using a minimum value option pricing
model with weighted-average risk free interest rates for 1997, 1998 and 1999 of
6.45%, 5.69% and 5.56%, respectively; no dividends; and a weighted-average
expected life of the option of five years. The fair value for options granted
subsequent to the initial filing date was estimated as of the date of grant
using the Black-Scholes pricing model and a volatility of 40%.

  The minimum value option valuation model with a near zero volatility results
in an option value similar to the option value that would result from using the
Black-Scholes option valuation model with a near zero volatility. The Black-
Scholes option valuation model was developed for use in estimating the fair
value of traded options which have no vesting restrictions and which are fully
transferable. In addition, option valuation models in general require the input
of highly subjective assumptions, including the expected stock price
volatility. Because the Company's stock options have characteristics
significantly different than those of traded options, and because changes in
the subjective input assumptions can materially affect the fair value estimate,
in management's opinion the existing models do not necessarily provide a
reliable single measure of the fair value of its stock options.

  For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The impact on
the pro forma results which follow may not be representative of compensation
expense in future periods when the effect of the amortization of multiple
awards may be reflected in the amounts. The Company's pro forma net loss from
continuing operations (net of income taxes) and pro forma basic and diluted net
loss per share follows:

 Warrants

  The Company issued warrants at various dates between 1991 and 1993 to
purchase up to 88,750 shares of Series A and Series B redeemable convertible
preferred stock in connection with certain equipment financing leases. These
warrants are exercisable at a price of $4.00 per share and 60,000 expired in
the three months ended June 30, 1999 with the remaining expiring in 1999 and
2001. In 1993, additional warrants to purchase up to 28,750 shares of common
stock at an exercise price of $.01 per share were issued under the anti-
dilution provisions of the warrants for Series A and B redeemable convertible
preferred stock and expire in 2001. In 1993, the Company issued a warrant to a
bank to purchase up to 25,000 shares of Series B redeemable convertible
preferred stock at an exercise price of $4.00 per share and a warrant to
purchase up to 25,000 shares of common stock at an exercise price of $.01 per
share. The warrants issued to the bank expire in 2000. These warrants were
accounted for at the fair value of the warrants on the date of issuance.

6. Income Taxes

  Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components
of the Company's deferred taxes are as follows:

</TABLE>

  The valuation allowance decreased by approximately $352,000 during the year
ended March 31, 1999 primarily as a result of utilization of net operating
losses which were not previously benefited. The valuation allowance increased
by approximately $813,000 during the year ended March 31, 1998.

  As of March 31, 1999, the Company had federal net operating loss
carryforwards of approximately $17,157,000 which will expire beginning in 2004,
if not utilized. The Company has alternative minimum tax credit carryforwards
of $196,000 which do not expire. Utilization of the net operating losses and
credit carryforwards may be subject to a substantial annual limitation due to
the "change in ownership" provisions of the Internal Revenue Code of 1986. The
annual limitation may result in the expiration of net operating losses before
utilization.

  Significant components of the expense (benefit) for income taxes attributable
to continuing operations are as follows:

  The tax benefit attributed to continuing operations in the years ended March
31, 1997 and 1998 results from the application of SFAS 109 to the sale of
discontinued operations (see Note 3). It is not expected that similar tax
benefits will be available to reduce future losses, if any.

  The Company's expense (benefit) for income taxes attributable to continuing
operations differs from the expected tax benefit amount computed by applying
the statutory federal income tax rate of 34% to income before income taxes as a
result of the following:

10. Restricted Cash

  At March 31, 1999, the Company had purchased irrevocable letters of credit
totaling $1,280,000 in favor of a lessor under a capital lease for equipment
representing seventy-five percent (75%) of the amount financed. These letters
of credit decline annually by 25%-33% of the original amount as long as no
event of default has occurred. These letters of credit are collateralized by
certificates of deposit.

  Under the lease agreement covering the Company's headquarters facility, the
Company was required to purchase an irrevocable letter of credit. The
requirement for the letter of credit extended through the earlier of the
expiration of the lease (November 2003) or four consecutive quarters of
profitability. As of June 30, 1999, the requirement of the letter of credit was
removed as a result of the Company attaining the fourth consecutive quarter of
profitability in the three months ended June 30, 1999.

Item 14. Indemnification of Directors and Officers

  Section 145 of the Delaware General Corporation Law (the "DGCL") provides
that a corporation may indemnify directors and officers, as well as other
employees and agents. A corporation may indemnify those individuals against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement in connection with specified actions, suits or proceedings, whether
civil, criminal, administrative or investigative (other than an action by or
in the right of the corporation). The individuals specified may be indemnified
in those actions, suits or proceedings if they acted in good faith and in a
manner they reasonably believed to be in or not opposed to the best interests
of the corporation. Additionally, in a criminal action or proceeding, these
individuals may be indemnified only if they had no reasonable cause to believe
their conduct was unlawful. A similar standard is applicable in the case of
actions or suits by or in the right of the corporation, except that:

  . indemnification only extends to expenses (including attorneys' fees)
    incurred in connection with the defense or settlement of such actions or
    suits; but

  . if the person seeking indemnification has been found liable to the
    corporation in respect of any claim, issue or matter, no indemnification
    shall be made except to the extent a specified court determines the
    person is fairly and reasonably entitled to indemnity for such expenses
    as the court deems proper.

The indemnification under the statute is in addition to any other
indemnification that may be granted by a corporation's charter, by laws,
disinterested director vote, agreement or otherwise.

  NetSolve's Bylaws provide that NetSolve shall indemnify its directors and
officers, and may indemnify its employees and agents, to the fullest extent
permitted by law. NetSolve believes that indemnification under its Bylaws
covers at least negligence and gross negligence on the part of indemnified
parties.

  In addition to the protection directors receive under NetSolve's By-laws,
the DGCL and the indemnity agreements, NetSolve's Restated Certificate of
Incorporation limits the liability of directors to the fullest extent
permitted by Delaware law. Delaware law provides that a corporation's
certificate of incorporation may contain

                                     II-1
<PAGE>

a provision eliminating or limiting the personal liability of directors to the
corporation or its stockholders for monetary damages for breach of their
fiduciary duties as directors, except for liability for:

  . any breach of their duty of loyalty to the corporation or its
    stockholders;

  . acts or omissions not in good faith or which involve intentional
    misconduct or a knowing violation of law;

  . improper payments of dividends or improper stock repurchases or
    redemptions as provided in Section 174 of the DGCL; or

  . any transaction from which the director derived an improper personal
    benefit.

  NetSolve has entered into agreements that indemnify its directors and
executive officers for certain expenses (including attorneys' fees) and, in
some instances, judgments, fines and settlement amounts they incur in certain
actions or proceedings. These actions or proceedings include any action by or
in the right of NetSolve, arising out of their services as a director or
officer of NetSolve, any subsidiary of NetSolve or any other company or
enterprise to which the person provides the services at the request of
NetSolve. NetSolve believes that these provisions and agreements are necessary
to attract and retain qualified directors and officers.

  At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent of NetSolve where indemnification will be
required or permitted. NetSolve is not aware of any threatened litigation or
proceeding that might result in a claim for such indemnification.

  Reference is also made to Section 8 of the underwriting agreement among
NetSolve, the selling stockholders and the underwriters, filed as Exhibit 1.1
to this registration statement, for a description of indemnification
arrangements between NetSolve, the selling stockholders and the underwriters.

Item 15. Recent Sales of Unregistered Securities

  Since October 1, 1995, NetSolve has issued and sold unregistered securities
as follows:

  Common Stock Issued Pursuant to Exercise of Warrants by Certain Investors. In
December 1997 and January 1998, NetSolve issued and sold an aggregate of
229,934 shares of common stock to four unaffiliated entities upon the exercise
of outstanding warrants at an exercise price of $0.01 per share. The warrants
had been issued in October 1992 and February 1993, in connection with the sale
of 229,934 shares of NetSolve's Series B Preferred Stock under NetSolve's
Series B Preferred Stock Purchase Agreement. Each of the warrant holders was a
party to such agreement.

  The sales and issuance of these securities were exempt from registration
under the Securities Act of 1933, as amended (the "Securities Act"), pursuant
to Section 4(2) on the basis that the transactions did not involve public
offerings.

  Stock Options Granted to Employees. The Company has granted options to
purchase its common stock to its employees under the 1988 Stock Option Plan and

Item 17. Undertakings

  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 14, 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
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of
whether such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

  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.

  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 that
  time shall be deemed to be the initial bona fide offering thereof.

                               POWER OF ATTORNEY

  Each director and/or officer of the registrant whose signature appears below
hereby appoints the Agent for Service named in this registration statement as
his attorney in fact to sign in his name and behalf, in any and all capacities
stated below, and to file with the Securities and Exchange Commission, any and
all amendments, including post-effective amendments, to this registration
statement, and the registrant hereof also appoints such Agent for Service as
its attorney-in-fact with like authority to sign and file any such amendments
in its name and behalf.

                                   SIGNATURES

  Pursuant to the requirements of the Securities Act of 1933, the undersigned
registrant has duly caused this Amendment No. 1 to its registration statement
on Form S-1 to be signed on its behalf by the undersigned, thereunto duly
authorized in the City of Austin, State of Texas, on July 26, 1999.

Paragraph 6 - COMPETITION
- -------------------------

A. NetSolve and AT&T shall not be precluded from competing against each other
for the same customer opportunity. However, (1) NetSolve shall not use customer
information that it obtains as a result of performing services hereunder or the
network designs developed hereunder to compete with AT&T or others; (2) NetSolve

B. Additionally, unless AT&T has given NetSolve prior written- consent, NetSolve

a supplier of contract services to AT&T. Such disclosure shall not be prohibited
if NetSolve is required in a judicial, administrative or governmental proceeding

Invoices shall be sent to AT&T at the address shown above, directed to the
personal attention of AT&T's Contract Representative, or other representative as
designated by AT&T. All undisputed amounts due shall be paid within forty-five

A.  This Agreement may be terminated:  (1) at any time by AT&T upon twenty-four

are not limited to Ameritech, Avantis, Bell Atlantic, Bell South, CompuServe,
LCI (Litel), MCI, NYNEX, Pacific Telesis Group, Southwestern Bell, Sprint, U.S.
West, and WorldCom (Wiltel/LDDS)]; or (2) upon thirty (30) days advance written
notice by either party if the other party fails to perform any material term or
condition of this Agreement and does not remedy the failure within the notice
period.

B.  Beginning January 1, 1998, a ten-month ramp-down period will take place.  If
AT&T terminates this Agreement pursuant to Paragraph 26(A)(1) or (2), there will
be no ramp-down period. If NetSolve terminates this Agreement pursuant to
Paragraph 26(A)(2), there will be no ramp-down period, however, NetSolve shall
be entitled to payment based upon the amount that would have been received had
the ramp-down period begun as of the effective date of termination. During the

period.

The following table illustrates the minimum target percentage of Router Sites
that will be supported by NetSolve during the ramp-down period. The actual
number of Router Sites that will be supported by NetSolve during the ramp-down

shortfalls resulting from customers' terminations of Router Sites.

     receiving party with its own proprietary information; and

NetSolve hereby acknowledges the sensitivity of the work as it may affect the
employees of AT&T, and NetSolve agrees to refrain from initiating any direct or
indirect communications with any employees of AT&T or its affiliated companies
without the prior written approval of AT&T, unless such communication is
required for NetSolve's fulfillment of its obligations under this Agreement.

       Upon thirty (30) days written notification by AT&T, a 12 month ramp-down
       period will take place. During this ramp down period, at AT&T's
       discretion, any or all existing ports supported by NetSolve may be
       transitioned. The number of ports that will be transitioned will be based
       on a percentage of the number of ports existing at the beginning of the
       ramp-down period.

       The following targets represent the minimum percentage of ports that must
       be supported by NetSolve during the ramp-down period, beginning the first
       month of the period:

       Ramp Down
       Period         Minimum Target Percentages to be Supported by NetSolve by
       ------         ---------------------------------------------------------
                      the end of the applicable three month period
                      --------------------------------------------

       Months 1-3     85% of the number of ports existing at the beginning of
                      the ramp-down period
       Months 4-6     60% of the number of ports existing at the beginning of
                      the ramp-down period
       Months 7-9     30% of the number of ports existing at the beginning of
                      the ramp-down period
       Months 10-12   0% of the number of ports existing at the beginning of
                      the ramp-down period

       For example: If NetSolve is supporting 1000 ports at the beginning of the
       ramp-down period, NetSolve must support 850 ports by the end of the third
       month, 600 by the end of the sixth month, etc. The actual number of ports
       that will be supported by AT&T during the ramp-down period will be
       determined by AT&T, at its discretion, but if the actual percentage of
       ports supported by NetSolve is less than the minimum target percentages
       stated above, AT&T shall pay NetSolve based upon the minimum targeted
       percentage at the rates established herein. Such payment shall constitute
       a full and complete discharge of Company's obligation.

       For example: If AT&T decides that NetSolve will only support 600 ports in
       month three, AT&T shall pay NetSolve for 850 ports in month three.

     additional CPE).
5.   Remote Bisync device (Point-point or Multi-point) to frame-relay attached

    conditions or covenants of this Agreement, or this Amendment No. 5, or any
    or all Orders placed hereunder and such breach or default shall continue for
    a period of thirty (30) days after the giving of written notice to the
    defaulting party thereof by the non-defaulting party, then in addition to
    all other rights and remedies of law or equity or otherwise (subject to the
    limitations under Paragraph 36 of the Agreement), the non-defaulting party
    at its discretion shall have the right to terminate any Orders placed by
    AT&T hereunder which are directly affected by such breach or default without
    any charge, obligation or liability whatsoever, except as to the payment for
    Services already received and accepted by AT&T. If this Agreement is

    month, or (2) decrease in the amount of monthly billing.

b)  The Agreement and all Orders under Attachments A, B and H may be terminated
    immediately by AT&T by notice in writing:

    acquisition by or merger with a competitor of AT&T.

d)  Termination of Individual Orders placed pursuant to this Attachment A-AT&T
    may terminate individual Orders for Router Sites without charge, upon 30
    days written notice, if: a) AT&T's customer is dissatisfied with the
    Services performed by NetSolve and NetSolve is unable to correct the
    Services to the customer's reasonable satisfaction within the 30 day notice
    period; or b) AT&T's customer is expanding and NetSolve is unable to provide
    the services defined in Attachment A or Attachment B.

e)  Following the Expiration Date (as outlined in Paragraph 3 of this Attachment
    A), a twelve month RampDown will take place and existing Router Sites may be
    transitioned to other management centers at AT&T's discretion.

    managed by NetSolve) shall not be less than the net amount billed in the
    last full month prior to the Expiration Date less 8% for each full month
    that has passed following the Expiration Date; however, no amounts shall be
    due after twelve (12) full months following the Expiration Date except for

    mutually agreed NetSolve should still provide service.

    part, wherein all or some portion of the work will be performed by Company
    itself or elsewhere, Supplier agrees to provide all reasonable efforts and
    full cooperation in the orderly transition of the work to Company designated

    continuation of the work transferred, continuation of work at reducing
    levels if necessary during a transition period and at reduced levels if work
    is transferred in part. Prices for additional work related to customer
    transition are covered in Table 1, Paragraph 4, Amendment 5 of this
    Agreement.

Company, its affiliates, its and their customers and each of their officers,
directors, employees, successors and assigns (all hereinafter referred to in
this Paragraph 30 as "Company") from and against any losses, damages, claims,
demands, suits, liabilities, fines, penalties and expenses (including reasonable
attorney's fees) that arise out of or result from: (1) bodily injuries or death
to persons or damage to real or tangible property, including theft, to the
extent caused (or until finally determined otherwise, alleged to have been
caused) by NetSolve's personnel or persons furnished by NetSolve to perform
installation, maintenance or similar services or Services on Company's premises
(provided that services or Services provided from a remote location, through
electronic means, will not be deemed to be furnished "on Company's premises");
(2) assertions under Workers' Compensation or similar acts made by persons
furnished by NetSolve or by any subcontractor or by reason of any bodily
injuries to such persons for which Company would be responsible under Workers'
Compensation or similar acts if the persons were employed by Company; (3) liens
against Company real or tangible property, or claims against Company, resulting
from NetSolve's failure to satisfy claims of subcontractors for payment for
labor, equipment or materials furnished by NetSolve under this Agreement; or (4)
any failure by NetSolve to perform NetSolve's obligations under this clause;
provided Company provides NetSolve prompt notice of any such claim, demand or
suit, fully cooperates in the defense and settlement thereof, and gives NetSolve
full control of the defense and settlement thereof. Notwithstanding the
foregoing, AT&T may join in the defense of any action, with its own counsel and
at its own expense, and in such circumstances, the parties' counsel will
reasonably coordinate their defense strategies. If a party is required, under a
proposed settlement, to take any action or refrain from taking any action, the
settlement may not be entered without such party's written consent, which will
not be unreasonably withheld or delayed.


The following paragraph is added to the Original Contract:

Paragraph 35 - INFRINGEMENT
- ---------------------------

NetSolve shall indemnify and save harmless AT&T, its affiliates, and their
customers, and each of their officers, directors, employees, successors and
assigns (all hereinafter referred to in this clause as AT&T) from and against
any losses, damages, liabilities, fines, penalties, and expenses (including
reasonable attorneys' fees) that arise out of or result from any proved or
unproved claim of infringement of any patent, copyright trademark or trade
secret right, or other intellectual property right or any other proprietary
interest to the extent arising from the use of any product or service provided
hereunder, and will pay any judgment rendered on such claim (each of such claims
called an "Infringement Claim"), provided AT&T provides NetSolve prompt notice
of any such claim, fully cooperates in the defense and settlement thereof, and
gives NetSolve full control of the defense and settlement thereof. NetSolve
further agrees that in the event that a lawsuit includes other claims in
addition to the indemnified infringement claims, AT&T shall retain sole control
of such other claims.

The foregoing obligations do not apply with respect to claims arising from or in
connection with: (i) equipment or products not bearing a NetSolve trademark
(such as Cisco routers, Bay Networks hubs and other third party equipment); (ii)
the combination of any product or service (including any Service) provided by
NetSolve with any service, product, data, process or material not obtained from
NetSolve hereunder, or (iii) any claim that could have been avoided if AT&T or
its customer had discontinued allegedly infringing activity after AT&T has been
advised of the alleged infringement and has failed to follow remedial actions
proposed by NetSolve. If any claim under exceptions (i) or (ii) is brought
against NetSolve, AT&T agrees to indemnify and defend NetSolve with respect to
each such claim (also called an "Infringement Claim"). If an Infringement Claim
arises solely from NetSolve's adherence to AT&T's written instructions regarding
services or tangible or intangible goods provided by NetSolve ("Items") and if
the Items are not (1) commercial items available on the open market or the same
as such items, or (2) items of NetSolve's designated origin, design or
selection, AT&T shall indemnify NetSolve. AT&T or NetSolve shall defend or
settle, at its own expense any demand, action or suit on any Infringement Claim
against the other for which it is the indemnitor under the preceding provisions
and each shall timely notify the other of any assertion against it of any
Infringement Claim and shall cooperate in good faith with the other to
facilitate the defense or settlement of any such claim.

The following paragraph is to be added to the Original Contract:

Paragraph 36 - LIMITATION OF  LIABILITY
- ---------------------------------------

Notwithstanding any other provision of this Agreement:

1) Neither party shall be liable for incidental or consequential damages or for
   loss of profits or revenue (all such damages referred to herein individually
   and collectively as "Indirect Damages") arising from or in connection with
   this Agreement or any service (including any Service) or product ordered or
   provided hereunder, whether or not foreseeable and whether or not based on
   breach of warranty, contract, negligence, strict liability, tort or
   otherwise; provided, however, that this limitation of liability shall not
   apply to "special damages" (e.g., lost wages) arising from bodily injury or
   death to persons, or to a party's obligations under the following Sections:

    a) Indemnity (provided, however, except for special damages arising from
       bodily injury or death to persons, NetSolve shall not be liable for
       Indirect Damages if a claim arises out of or in connection with the use
       or supply of any product or service (including any Service) obtained
       hereunder, and AT&T could legally have disclaimed liability for such
       Indirect Damages in its contract with its customer).

    b) Infringement

    c) Insurance (provided NetSolve's liability for breach of the Section
       entitled "Insurance" shall not exceed the liability that would have
       existed if NetSolve had complied with the provisions of such Section)

    d) Compliance with laws.

    e) Use of Information (provided that this exception will apply only to a
       willful breach by a party of its obligation not to disclose to
       unauthorized third parties confidential information regarding the other
       party's customers. In the event of such a breach: (i) the breaching
       party's total aggregate liability, for direct damages, Indirect Damages
       or otherwise, arising from or in connection with such breach shall not
       exceed one million dollars ($1,000,000) in total; and (ii) damages
       awarded under this exception (e) will not "count" toward the aggregate
       damage limit set forth in subsection 2 below. The party alleging such a
       breach will have the burden of proving all elements of the alleged breach
       and any alleged damages, including willfulness, proximate causation and

       willful breach by a party of its obligation not to disclose to
       unauthorized third parties confidential information regarding the other
       party's customers. In the event of such a breach: (i) the breaching
       party's total aggregate liability, for direct damages, Indirect Damages
       or otherwise, arising from or in connection with such breach shall not
       exceed one million dollars ($1,000,000) in total; and (ii) damages
       awarded under this exception (e) will not "count" toward the aggregate
       damage limits set forth above. The party alleging such a breach will have
       the burden of proving all elements of the alleged breach and any alleged
       damages, including willfulness, proximate causation and amount of
       damages, which must be capable of being ascertained with substantial
       certainty.)

End User Responsibilities
- -------------------------

  A. The End User is responsible for managing all non-Network Components,
     including the LAN or other network environment located on the local side of
     the CSU. If in connection with providing FRP3 services, NetSolve isolates
     the problem to be on the LAN side of the Network Components, an NMC
     engineer will consult with the End User and obtain written authorization
     prior to performing additional work, which will be at NetSolve's standard
     rates for Professional Services. In the event such work is approved and the
     problem is finally determined to be with a Network Component, no such
     additional charges will be billed to the End User.

  B. Provide, install, and configure the necessary local network equipment (i.e.
     router, FRAD, etc.), to gain access to the PAM via the appropriate
     management PVC

  C. Provide and install the PC equipment necessary for operating the PAC
     software in accordance with the manufacturers specification

  D. Install the PAC software on the customer provided PC(s)

  E. The End User must provide the NMC with notice of any changes which the End
     User intends to make to the Network Components before such changes are
     made.


                                                                          5 of 5

Software Management
- -------------------
  A.  Provide NetSolve with authorized copies of software which AT&T requests
      NetSolve to install on End User  or AT&T Network Components.


General
- -------
  A.  AT&T or End User is responsible for managing all network elements that are
      not a part of Network Components. If, while performing its management
      services, NetSolve isolates issues beyond Network Components, a NetSolve
      network engineer will consult with the AT&T and obtain written
      authorization prior to performing additional work, which will be at
      NetSolve's standard rates for Professional Services. In the event such
      work is approved and the problem is finally determined to be with a
      Network Component, no such additional amounts will be charged to AT&T.

  B.  The End User must provide a 1FB phone line, or dedicated PBX extension
      with DID capability, prior to the install date at each site covered by
      NetSolve's services hereunder to allow dial-in access by NMC personnel.
      These lines must be connected to a dial modem provided by the End User.

  C.  The End User and/or AT&T must provide NetSolve with notice of any changes
      which are intended to be made to the Network Components before such
      changes are made.

  D.  End User is responsible for managing the "non-IMA" network environment,
      defined as equipment and services located on the End User side of the
      demarc.

  E.  It is recommended that End User at all times have maintenance coverage for
      all CPE equipment included in network components. NetSolve recommends that
      central sites have a minimum of 7x24 coverage with a four hour response.
      NetSolve will work with End User to develop alternative maintenance
      strategies if desired (on-site spares, e.g.).

  F.  For optimal service, NetSolve recommends that the End User obtain
      registered IP addresses for applicable network components or agree to use
      unregistered IP addresses assigned by NetSolve. Secondary addressing
      support is also available, but reduces NetSolve's troubleshooting
      abilities.

  G.  The End User and/or must purchase an in-band management channel to
      NetSolve to monitor CPE IMA.


                                                                          6 of 6

         mutually agreed schedule.

    5.   Upon isolation of the fault, NetSolve will dispatch the appropriate
         service entity (End User's carrier or End User- or AT&T-designated
         equipment maintenance provider).

    6.   Close maintenance issues with End Users to their satisfaction.

    7.   When fault isolation procedures indicate a problem with non-Network
         Components, NetSolve will provide End User with information gathered
         during the fault isolation process in an effort to aid End User in
         restoring service.  If the information is sufficient to open a ticket
         using AT&T's automated systems, NetSolve will open this ticket at the
         customer's option. (This procedure is called a Warm Hand Off).

    8.   When fault isolation procedures indicate that the problem is not with
         the End User frame relay access arrangement, NetSolve will execute
         additional mutually agreed to connectivity tests to further isolate the
         problem within AT&T's backbone production and Trial IPFR networks. When
         the problem is identified, NetSolve will notify the designated IPFR
         AT&T maintenance organization according to mutually agreed notification
         procedures to initiate remedial repair efforts. When mutually agreed to
         between AT&T and NetSolve, NetSolve may expand the scope of the IPFR
         management services by manipulating the Trial IPFR network components
         to effect the repair.

    services, NetSolve isolates issues beyond Network Components, a NetSolve
    network engineer will consult with AT&T and obtain written authorization
    prior to performing additional work, which will be at NetSolve's standard
    rates for Professional Services. In the event such work is approved and the
    problem is finally determined to be with a Network Component, no such
    additional amounts will be charged to AT&T.

B.  The End User and/or AT&T must provide NetSolve with notice of any changes
    which are


                                                                          5 of 6

                                                        To Agreement No. GSA005D


    intended to be made to the Network Components before such changes are made.

C.  End User is responsible for managing the "non-IPFR" network environment,
    defined as equipment and services located on the End User side of the
    demarc.

D.  It is recommended that End User at all times have maintenance coverage for
    all CPE equipment included in network components. NetSolve recommends that
    central sites have a minimum of 7x24 coverage with a four hour response.
    NetSolve will work with End User to develop alternative maintenance
    strategies if desired (e.g. on-site spares).

E.  For optimal service, NetSolve recommends that the End User obtain registered
    IP addresses for applicable network components or agree to use unregistered
    IP addresses assigned by NetSolve. Secondary addressing support is also
    available, but reduces NetSolve's troubleshooting abilities.

F.  The End User and / or AT&T must purchase an in-band management channel to
    NetSolve to monitor appropriate IPFR Network Components.

the event of any conflict between the terms of this Attachment and the terms of
the Agreement, the terms of this Attachment shall prevail with respect to the
Services provided under this Attachment N.

For purposes of this Attachment N only the following Paragraphs in the Agreement
are deleted in their entirety and replaced with the Paragraphs below:

Paragraph 1 - Statement of Work

NetSolve shall provide Services to AT&T in support of AT&T's ATM PLUS Service
offering in accordance with the "Statement of Work," Attachments N-1 and N-2
attached hereto.  Services shall be available to AT&T in the United States.
Modifications to this Statement of Work and its requirements as set forth in
Attachments N-1 and N-2 may be requested from time to time by AT&T.  The pricing
contained herein shall apply to Services requested or any modification, provided
that the modifications requested do not require the furnishing of more material
or labor by NetSolve or longer times for performance of services.  NetSolve
shall immediately notify AT&T's Contract Representative, in writing, of any
requested modification which NetSolve reasonably believes  will require an
increase to the prices contained in Paragraph 4 - Payment for Services, and
shall furnish the amount of such proposed increase in such writing with
appropriate supporting documentation substantiating the basis for the requested
price increase.  Following delivery of such notice, NetSolve shall not proceed
with Services with any such modification until AT&T and NetSolve Contract
Representatives  (as then designated and authorized)  agree, in writing, to the
appropriate charges.

"Orders" for Services pursuant to this Attachment N shall be sent to NetSolve
via a mutually agreed upon method.  Monthly recurring Service charges as further
described in Paragraph 4 shall commence on the start date of Services as
requested by AT&T (such date is herein defined as the "CRD") and continue for
the number of months specified by AT&T on the order from AT&T to NetSolve, but
in no case greater than 36 months (the "Service Term"). The agreement term for
ordering ATM PLUS Service is set forth in Paragraph 3.

Upon expiration or termination of this Attachment N, all Services will continue
to be provided through the end of each End User Service Term and will be non-
cancelable by either party except as set forth in Paragraph 24 of this
Attachment N.


Paragraph 2 - Contract Representative:
AT&T's Contract Representative for this Attachment N is Kelly A. Donnelly,
BNSVC.  AT&T will notify NetSolve in writing if a new Contract Representative is
designated by AT&T.

Paragraph 3 - Term

The effective date of this Attachment N is March 1, 1999 and it shall end on
February 28, 2001; provided, however, that this Attachment N and the Agreement
shall continue in effect beyond February 28, 2001 with respect to specific End
User service terms only which extend beyond the Term of this Attachment N and
the Agreement, except that in no event shall NetSolve be obligated to provide
Services to such specific End Users more than three (3) years after February 28,
2001.




                                                                          2 of 6

Amendments Number 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10  (collectively the
"Agreement") is further amended as follows effective as of August  1, 1999
("Amendment No. 11.0).

The previous Attachments A, B, D, H and H-1, and Appendices A and B, to
Amendment Number 5 are hereby deleted.

Paragraphs 1-4, 7 and 24 are to be deleted in Amendment Number 5 and replaced
with the following for purposes of this Amendment No. 11.0. All other paragraphs
of Amendment Number 5 remain in effect with respect to this Amendment Number
11.0. All paragraphs of Amendment Number 5 other than 1-4 and 7 remain in effect
with respect to any other amendments to the Contract to which those paragraphs
are in effect as of the date of this Amendment Number 11.0.

Paragraph 1 - Statement of Work
- -------------------------------

NetSolve shall provide Services to AT&T in support of AT&T's Managed Network
Solutions (MNS) Service offering in accordance with the "Statement Of Work,"
(which is comprised of Attachments A, H and H-1, Appendices A and B). Services
shall be available to AT&T in the United States and Canada and, subject to
mutual agreement on pricing and DMOQs, in other countries. Modifications to the
Statement of Work may be requested from time to time by AT&T and any
modifications to Attachments A, H, H-1 or Appendices A and B shall be approved
and incorporated into this Amendment Number 11.0 upon the written agreement of
both parties.  The pricing contained herein shall apply to Services requested or
any modification, provided that the modifications requested do not require the
furnishing of more material or labor by NetSolve or longer times for performance
of services.  NetSolve shall immediately notify AT&T's Contract Representative,
in writing, of any requested modification which NetSolve feels will require an
increase to the prices contained in Paragraph 4-Payment for Services, and shall
furnish the amount of such proposed increase in such writing.  Following
delivery of such notice, NetSolve shall continue to provide Services without
modification but shall not  institute any such modification until the AT&T
Contract Representative and NetSolve agree, in writing, to the appropriate
charges.

Paragraph 2 - CONTRACT REPRESENTATIVE
- -------------------------------------

AT&T's MNS Contract Representative is Charles Mantione.  AT&T will notify
NetSolve in writing if a new Contract Representative is designated by AT&T.


Paragraph 3 - TERM
- ------------------

The effective date of this Amendment Number 11.0 is August 1, 1999 ("Effective
Date"). AT&T may place Orders with NetSolve under this Amendment Number 11.0
from the Effective Date through and including December 31, 2001 (the "Ordering
Period").  NetSolve shall provide Services for Orders placed under this
Amendment Number 11.0 for the duration of the Service Term for each end user
customer.  The Service Term for each Order will start with the initial
installation for each end user customer and will end as of the earlier of (i)
the cancellation of individual Orders by AT&T in accordance with Paragraph 24 of
this Amendment Number 11.0; or (ii) December 31, 2004.  This Amendment Number
11.0 will terminate upon expiration of the Service Terms of all Orders under
this Amendment subject to earlier termination in accordance with this Amendment
Number 11.0  (the "Expiration Date"). The Service Term  for each Order from AT&T
to NetSolve shall be based on the  actual term of the end user customer's order
with AT&T.

                                                                          Page 1
<PAGE>

Any other extensions of this Amendment Number 11.0 beyond the Expiration Date,
or any other continued work beyond the Expiration Date, shall be pursuant to a
written Agreement signed by both parties.


Paragraph 4 - PAYMENT FOR SERVICES
- ----------------------------------

A.  For services performed by NetSolve under this Amendment Number 11.0, AT&T
will pay NetSolve a monthly recurring charge for each Router Site. The monthly
recurring charges are set forth in Tables 1, 2A, 2B and 3 below. In addition,
AT&T will pay certain one time, non-recurring charges and Time and Material
(T&M) charges as set forth in Table 1 below. These prices are net to AT&T and
not subject to additional discount unless mutually agreed in writing. The
thirty-six (36) month pricing for Item 2 in Table 1, as set forth in Tables 2A
and 2B, will be applied to all existing orders effective with the Effective
Date.


B.  The following is fixed for the term of this Amendment Number 11.0:

     (i)  Prices for the services in Items 1, 2, 3, 7, 8, 9, and 10  of Table 1,
     and
     (ii) The percentage fees in Item 5.

  The following pricing may change during the term of this Amendment Number
  11.0:
     (i)  Prices for Item 5, as based on the actual manufacturer's invoice or
     list price, and/or
     (ii) Prices for Items 4 and 6 upon sixty (60) days written notice, only if
     NetSolve's suppliers change the underlying prices to NetSolve.  (In which
     case NetSolve shall only change its prices to AT&T by the same percentage
     (up or down) as the percentage change from NetSolve's suppliers to
     NetSolve.)  Provided, however, that if a price increase exceeds 5% NetSolve
     shall use reasonable efforts to find a substitute supplier.

Any change to the price per Item 4 (pursuant to the terms above) shall be
applied to new Orders placed by AT&T after AT&T's receipt of NetSolve's notice
of the price change.

Any change to the price for Item 6 (pursuant to the terms above) shall be
applied to new Orders placed by AT&T after AT&T's receipt of NetSolve's notice
of the price change, or for existing Orders, the new pricing shall be applied as
of the next annual anniversary of the service start date for each existing
Order.

AT&T and NetSolve shall cooperate in efforts to persuade any mutual supplier
(e.g. Cisco) to provide (i) fixed pricing for the duration of any Orders placed
pursuant to this Amendment Number 11.0 and (ii) cancellation or termination
flexibility.  Such cancellation or termination flexibility may include
provisions to allow NetSolve to assign any applicable contracts or orders for
maintenance to AT&T in the event AT&T cancels such services with NetSolve as
permitted under Paragraph 24.

     Footnotes to Table 1:

     (1) Subject to 100% credit if network is managed by NetSolve (see Paragraph
       4 of Attachment H).

     (2) This charge is waived for Orders accepted by NetSolve prior to the
         Effective Date. This charge will apply for such Orders upon expiration
         of the current term per the end user customer Order to NetSolve from
         AT&T.

     (3) This fee may be deferred by increasing the monthly recurring charge.
         See Table 3 below.

     (4) Additional charge at Time and Materials rate (see Item 8 in Table 1)
         for installations completed outside of 8:00 a.m. to 5:00 p.m. local
         time Monday through Friday.

     (5) This process will be used for all router orders received from AT&T
         after August 15, 1999. It may be used for router orders prior to that
         date at NetSolve's option in order to manage the transition. Prior to
         the transition, the process for `Other Equipment' in Item 5 above will
         be utilized.

     (6) The cost of the equipment will be invoiced as the equipment is received
         from the manufacturer. The percentage fee will be invoiced as the
         equipment is shipped to the end user customer. NetSolve will provide a
         monthly report detailing all inventory held by NetSolve which has been
         billed to AT&T and not yet shipped to the end user customer.

    (7)  Maintenance services purchased utilizing NetSolve's vendor may only be
         canceled by AT&T upon sixty (60) days written notice prior to each
         anniversary of the service start date even if it results in NetSolve
         providing maintenance services beyond the term of providing the
         services in Item 2 of Table 1 (except that AT&T shall not be obligated
         to continue maintenance services more than ninety (90) days following
         the end of the term per the Order).

Table 2
- -------

     The price to AT&T for the services under Item 2 of Table 1 are set forth
     below and are based on the Service Term and number of sites per each
     individual Order.  No more than one end user customer can be included on a
     single Order.

     If an end user customer adds additional sites and that end user customer
     has enough sites in total to qualify for a lower price, the lower price can
     be obtained only through the replacement of existing Orders with a new
     Order containing all of the served sites for a new service term.

     All of the sites on each Order shall be installed within the Ramp-Up Period
     (defined as one-hundred-eighty (180) days after installation of the first
     site on the Order, unless AT&T and NetSolve mutually agree otherwise on a
     case by case basis).  If all of the sites under an Order are

<PAGE>

     not installed within the Ramp-Up Period, then NetSolve may bill AT&T based
     on the actual number of installed sites for that Order. Such price will be
     utilized only prospectively (i.e., there will be no adjustments to billing
     for prior months). Provided, however, that if the failure to meet the Ramp-
     Up schedule is due to NetSolve installation delays, then NetSolve shall
     bill AT&T based on the number of sites in the Order until the NetSolve
     delay is cured.

     If a customer cancels sites, NetSolve may base the pricing on the remaining
     number of sites.  Provided, however, that if a customer cancels sites, due
     to a business downturn, then NetSolve shall not increase the price if the
     decrease in the number of sites results in a drop of only one level in
     Table 2A and/or Table 2B. Notwithstanding the foregoing, NetSolve may base
     the pricing on the remaining number of sites if (i) AT&T has increased its
     price to the end user customer or (ii) the decrease results in the number
     of sites falling into the first level of Table 2A and/or Table 2B.

     The pricing in Table 2A shall apply to Orders existing as of the Effective
     Date of this Amendment No. 11.0.  The pricing in Table 2B shall apply to
     all new Orders placed after the Effective Date of this Amendment.
     Provided, however, that Table 2A pricing shall apply to all Orders if at
     any time during the term of this Amendment, the total average number of
     router sites (new orders and existing customers) managed by NetSolve
     hereunder is less than 11.  Further provided that once the total average
     number of router sites managed hereunder is 11 or more, Table 2B pricing
     shall then apply to all new Orders.

Paragraph 7 - INVOICING AND PAYMENT
- -----------------------------------

Invoices for recurring monthly charges and maintenance shall be sent monthly in
advance by NetSolve, based on the number of Router Sites installed and
maintained as of the date the invoice was sent. Invoices for equipment purchased
from NetSolve shall be sent when the equipment is shipped by NetSolve to the
Router Site. Invoices for routers will be sent upon receipt by NetSolve of the
equipment. When the implementation of the end-user customer's network is
complete and operational NetSolve will invoice AT&T for the one-time, non-
recurring charges associated with the coordination and installation of equipment
(including the percentage fee for routers in Item 5 of Table 1). Invoices shall
be sent to AT&T at the address shown below, directed to the personal attention
of the person indicated below, or other representative as designated by AT&T.
All undisputed amounts due shall be paid within forty-five (45) days after
AT&T's receipt of the invoice. Any unpaid disputed amount shall be documented in
writing by AT&T prior to the due date. A late charge of one-percent (1%) per
month on all amounts not paid or disputed in writing within sixty (60) days of
receipt of the invoice will be payable by AT&T.

Paragraph 24 - TERMINATION
- --------------------------

Termination of the Agreement  - The termination of the Agreement shall not
affect the rights and obligations of either party under this Amendment Number
11.0, and this Amendment Number 11.0  (and the provisions of the Agreement with
respect to this Amendment Number 11.0) shall continue in effect as though the
Agreement had not been terminated

Termination of this Amendment Number 11.0. -

a)  In the event either party shall be in breach or default of any of the terms,
    conditions or covenants of this Agreement, or this Amendment Number 11.0 and
    such breach or default continues unremedied twenty-five (25) days after
    receipt of written notice, the non-defaulting party may terminate any Orders
    that are directly affected by such breach or default without any charge,
    obligation or liability. Notwithstanding the foregoing, AT&T's obligation to
    pay (i) for Services already received and accepted by AT&T, (ii) any charges
    due under Table 3 of Paragraph 4, and (iii) if AT&T is the defaulting party,
    the cancellation charges provided for in Paragraph 24e)i), shall not be
    excused. If this Agreement is terminated by AT&T due to NetSolve's breach or
    default, AT&T may begin a Ramp-Down period, not to exceed twelve (12)
    months, to transition existing Router Sites to other management centers
    without limitation as to the number of sites transitioned per month. In the
    event of such Ramp Down, the pricing shall not change, unless any such price
    change is made pursuant to Paragraph 4B.

b.) The Agreement and all Orders under Attachments A and H may be terminated
    immediately by AT&T by notice in writing:

    i)  if NetSolve makes an assignment for the benefit of creditors (other than
    solely an assignment of moneys due);

    ii) if NetSolve evidences an inability to pay debts as they become due,
    unless adequate assurance of such ability to pay is provided within thirty
    (30) days of such notice;

    iii) if a proceeding is commenced under a provision of the United States
    Bankruptcy Code, voluntarily by NetSolve;

    (iv) if a proceeding is commenced under a provision of the United States
    Bankruptcy Code, involuntarily, against NetSolve, and such proceeding is
    not dismissed within thirty (30) days.

c)  NetSolve shall provide AT&T with written notice, as soon as it may legally
    do so, if NetSolve merges with or is acquired by a competitor of AT&T. AT&T
    may terminate this Agreement at any time, without termination liability,
    within the thirty day period following AT&T's receipt of written notice of
    the merger/acquisition. During the first twelve months of the migration the
    pricing for each Order shall not change (unless such pricing change is made
    pursuant to Paragraph 4B). Pricing for end user customers still managed by
    NetSolve after the first twelve months of migration shall be separately
    negotiated by the parties.

d)  Termination of Individual Orders placed pursuant to this Attachment A-AT&T
    may terminate individual Orders for Router Sites without charge, upon 30
    days written notice in the event AT&T has received a written notice from the
    end user customer that such end user customer: (i)is expanding and NetSolve
    is unable to provide the services defined in Attachment A; (ii) has
    terminated its services with AT&T due to a business downturn; or (iii) the
    Service Term has expired.

    The following shall apply with respect to Orders entered into prior to July
    1, 1999 and terminated pursuant to Paragraph 24d)iii):

     1.  No Orders may be terminated prior to July 1, 2000.


                           AT&T/NETSOLVE PROPRIETARY

                                                                          Page 7
<PAGE>

    2.   No more than 150 Router Sites may be moved in any month.

    3.   AT&T must provide NetSolve ninety (90) days written notice of any
         Router Sites it moves.

    4.   If AT&T moves Router Sites under Paragraph 24d)iii) and the total
         number of Router Sites remaining in the NetSolve Network Management
         Center under this Amendment Number 11.0 decreases by eight percent (8%)
         or more in any ninety (90) day period, then NetSolve may reject Orders
         for new end user customers in its sole discretion.

    5.  The pricing for Orders migrated under this Paragraph 24e) shall not
        increase and shall not revert to 12 months rates.

e.)  In addition to its termination rights under Paragraphs 24a) through 24d)
above, AT&T may cancel this agreement or individual Orders under this Agreement
for any or no reason (termination for convenience) as set forth in this
Paragraph 24e).

  i)   AT&T may cancel individual Orders entered into after June 30, 1999 upon
       thirty (30) days written notice. In the event of such cancellation, AT&T
       shall pay a cancellation charge equal to: (1) 50% of any unpaid Monthly
       Recurring Fees (defined as the fees under Item 2 of Table 1, Paragraph
       4), whether previously invoiced or not, for months 1 through 24 of the
       Service Term of the canceled Order, plus (2) 25% of any unpaid Monthly
       Recurring Fees, whether previously invoiced or not, for months 25 through
       36. There is no cancellation charge for any canceled Service Term beyond
       36 months. Cancellation under this Paragraph 24e)i) is limited in any
       twelve (12) month period to Orders with aggregate Monthly Recurring Fees
       not exceeding ten percent (10%) of the aggregate total of Monthly
       Recurring Fees for all Orders as of the first month of such twelve (12)
       month period.

  ii)  All Orders under this Amendment Number 11.0 may be terminated on twelve
       (12) months written notice. At the end of the twelve (12) month notice
       period or July 1, 2001, whichever is later, a twelve month Ramp-Down will
       begin. Each month during the Ramp-Down, AT&T shall transition no more
       than 8% of the existing sites away from the NetSolve management center.
       After the 12 month Ramp-Down, Router Sites will still be managed by
       NetSolve only upon the mutual agreement of NetSolve and AT&T. During the
       12 month Ramp-Down, the cancellation charges under Paragraph 24e)i) will
       apply to each Order for which the Service Term has not expired as of the
       date of the move. Following receipt of the notice of termination under
       this Paragraph 24e)ii), NetSolve may reject Orders for new end user
       customers in its sole discretion.

f)  In the event of expiration or termination of this Agreement, in whole or in
    part, wherein all or some portion of the work will be performed by AT&T
    itself or elsewhere, NetSolve agrees to provide all reasonable efforts and
    full cooperation in the orderly transition of the work to AT&T designated
    Network Management centers, provision of reports, data configuration files
    and similar customer specific information and media necessary for
    continuation of the work transferred, continuation of work at reducing
    levels if necessary during a transition period and at reduced levels if work
    is transferred in part. Prices for additional work related to customer
    transition are covered in Table 1, Paragraph 4, Amendment Number 11.0 of
    this Agreement.

g)  Notwithstanding any other provision of Paragraph 24, the equipment
    maintenance services under Item 6 of Table 1, Paragraph 4, may be canceled
    only upon an annual anniversary of the maintenance service start date unless
    there is an uncured default in the providing of such maintenance services.
    Notwithstanding any other provision of Paragraph 24, the fees in Table 3
    remain non-cancelable and must be paid in a lump sum for the remainder of
    the term per the Order within thirty (30) days of the notice of termination
    unless there is an uncured default in the providing of those specific
    services.

Network Availability Metrics

For purposes of these sections the following are defined as:


Network Component: all NetSolve-provided or approved components,  in a network
designed and mutually agreed upon  utilizing service and equipment providers
approved by NetSolve, including the frame relay ports and PVCs, local access to
AT&T's frame relay switch, T1 multiplexers, CSU/DSUs, routers (to the router LAN
port), and cabling between such units, which are covered by Services under a
Order accepted by NetSolve.

Link or Network Link: the logical connection between two customer sites covered
by NetSolve Services and consists of all of the Network Components required for
connectivity between such sites.

Downtime: the total time in a given month, measured in minutes for each Network
Link, that a Network Link is not available to the customer. For purposes of
determining whether the Network Availability target is met, Downtime excludes
outages resulting from (i) any operator error, improper act , or omission of
AT&T, AT&T's end user customer, or the affiliates, representatives,  invitees,
licensees, vendors, or the like of either of them; (ii) inaccurate information
provided to NetSolve by AT&T or AT&T's end user customer; (iii) failure of any
facilities, equipment, services, or the like which are not Network Components,
including but not limited to LAN components; (iv) failure of AT&T or AT&T's end
user customer to perform any of their respective responsibilities under the
Agreement or this Attachment A; (v) unavailability of AT&T or AT&T's end user
customer personnel to grant NetSolve access to facilities as required for
NetSolve to perform its responsibilities; (vi) preventive or scheduled
maintenance activities of AT&T, AT&T's end user customer, or any other third
party not a sub-contractor or otherwise directed or consented to by NetSolve; or
(vii) any  large scale outage of the AT&T network or a network segment, or a
significant portion of either thereof.  This time will not be excluded from the
reported DMOQ, however this time will be excluded from the calculated credits.

Network Availability: the aggregate link minutes in one month (links multiplied
by minutes) minus the Downtime minutes, all divided by the aggregate link
minutes in one month (links multiplied by minutes) expressed as a percentage for
each month. Network Availability includes the physical layer, the data link
layer and the network layer of the Network, provided that the source of the
problem(s) is a Network Component.

Pro-Active Monitoring Metrics

NetSolve is responsible for first contact with customers for proactive trouble
monitoring for any customer's network. Pro-Active Monitoring is defined to mean
contacting the customer before the customer calls in and, in any event, within
30 minutes of receipt of alarm (managed devices only). This metric does not
apply in the event of a large-scale network outage which would affect more than
20% of the customers being managed by NetSolve.

                                                                         Page 13

Installation Metrics On-Time Installation (First Sites) - Since Installations
                     ----------------------------------
and MACs are scheduled by NetSolve Project Implementation Managers with the end-
user customer, it is imperative that  the service provider arrive on the
scheduled date and time.  Arrival at the customer premise must be in ample time
to allow the installation to be completed successfully and service turned up on
the scheduled date. On- Time Installation (First Sites) means the customer's
initial two sites were successfully installed on the scheduled installation
date. The scheduled installation date is determined by the later of (i) 60 days,
from contract acceptance by AT&T; (ii) the customer requested due date; or (iii)
50 days from receipt by NetSolve of a Order executed by AT&T.

On-Time Installation (Overall) - On time Installation (Overall) means all of the
customer's sites installed after the initial two sites were successfully
installed on the scheduled installation date.


Maintenance Metrics

Mean Time To Restore (MTTR) - Overall shall be defined as the arithmetic mean of
the time to clear trouble tickets (utilizing Downtime eligible for calculating
credits as the measure of Time To Restore).

Mean Time To Restore (MTTR) With Dispatch shall be defined as the arithmetic
mean of the time to clear trouble tickets (utilizing Downtime eligible for
calculating credits as the measure of Time To Restore) when dispatching of a
technician (LEC or equipment maintenance) is required to restore the customer's
network to satisfactory operating condition.


Call Receipt

NetSolve shall produce monthly reporting showing the Average time MNS customers
wait in queue to be picked up for trouble reporting. This metric does not apply
in the event of a large-scale network outage which would affect more than 20% of
the customers being managed by NetSolve.


Credits for Missed DMOQ's

If NetSolve fails to meet the target monthly objectives in any month, NetSolve
shall provide AT&T with a credit in each succeeding month  that the target
objective is not met. The credits associated with each performance metric are
set forth in the following table. In no event will the credits for Network
Availability, Pro-Active Monitoring, Mean Time to Restore Overall, or Mean Time
to Restore with Dispatch with respect to a customer site in any given month
exceed the total net billings to AT&T by NetSolve for that month for the charges
for the affected router managed hub sites and router managed non-hub sites set
forth in Item 2 of Table 1 in Paragraph 4 of Amendment Number 11.0. In no event
will the credits for On-Time Installation (First Sites), On-Time Installation
(Overall), and Customer Satisfaction Metrics - Installation (below) exceed the
total net billings to AT&T by NetSolve for the charges for installation set
forth in Item 4 of Table 1  in Paragraph 4 of Amendment Number 11.0.


No  credit will be issued by NetSolve for any DMOQ  for a particular customer to
the extent the   missed DMOQ is caused by a negligent act, omission or failure
of AT&T or its affiliates, service supplier, or end user customer. In the event
any act, omission, or failure of AT&T's service suppliers  (but not AT&T or its
affiliates) can be reasonably managed by NetSolve to increase the DMOQ, NetSolve
will attempt to work with that service supplier to increase that supplier's
performance if such work does not, in NetSolve's sole opinion, significantly
increase NetSolve's costs.

Network Availability    If NetSolve does not achieve a Network Availability rate of ninety-nine and one-half percent
                        (99.5%) for any customer's network during any two (2) months of a rolling twelve (12) month
                        period, NetSolve shall provide AT&T with a one (1) month credit for the net monthly fees for
                        the charges set forth in Item 2 of Table 1 Paragraph 4 of Amendment Number 11.0 for all the
                        Router Sites associated with the customer.

Customer Satisfaction Requirements - If any NetSolve activity ( installation or
maintenance)  is concluded by any AT&T end-user to be  unsatisfactory,   and
AT&T provides a credit for such performance, the following  credit is due to
AT&T. No credit shall be due to AT&T if the service failure is due solely to any
act, omission, or failure of AT&T or its service suppliers set forth below.  If
the service failure is due in part to any act, omission or failure of NetSolve
or NetSolve suppliers, and AT&T or AT&T suppliers, the credit should be reduced
by 50% of the amount calculated below.

Miscellaneous
- -------------

Insufficiently Prepared Site - In the event that NetSolve or its supplier
arrives at a site and cannot complete an installation and must be dispatched a
second time due to the site being insufficiently prepared, NetSolve will bill
AT&T T&M charges incurred  (this is in addition to the standard installation
fee). T&M charges will not apply if the site is prepared in accordance with the
site survey instructions and the instructions are reasonably deemed
inappropriate or inadequate and the condition giving rise to such assessment are
reported to NetSolve in writing.

For purposes of this Attachment the following Paragraphs in the Agreement are
replaced with the Paragraphs below:

Paragraph 1 - Statement of Work

NetSolve shall provide contract services to AT&T in support of AT&T's Growth
Markets Sales Process in accordance with the "Statement of Work," Attachment H-1
hereto.  Variations to this Statement of Work and its requirements as set forth
in Attachment H-1 may be requested from time to time by AT&T without the need
for formal amendment of Attachment H-1. The pricing contained herein shall apply
to services requested or any variations, provided that the variations requested
do not require the furnishing of more material or labor by NetSolve or longer
times for performance of services.  NetSolve shall immediately notify AT&T's

1.  Overview

NetSolve and AT&T Growth Markets wish to streamline the cycle time, and improve
accuracy in the design and pricing of the new bundles for Managed Router
Services. NetSolve will develop a network design and price quote for
opportunities generated by AT&T's Growth Markets sales organization that fit
within the new MRS bundles.


2.  NetSolve  Pre-Sales Responsibilities


2.1  Interview prospect

Pre-qualification forms for MRS bundled services will be sent to NetSolve.  Upon
receiving a pre-qualification form, NetSolve will contact a prospect and conduct
a technical interview to gather the necessary information to design and price a
Managed Router bundle. The initial prospect call will be made within one
business day of receipt of the pre-qualification form. Although NetSolve will
attempt to contact the prospect within one business day, the prospect's schedule
and knowledge of their network dictate the actual time required for interview
completion. If NetSolve is unsuccessful in obtaining an interview schedule with
the prospect after three attempts (including voice mail), the qualification form
will be returned to the appropriate DNAE and DNSM for follow up.


NetSolve will also assist in proposal closure by providing support to the DNAE
and, where mutually agreed by AT&T and NetSolve, assisting in or making customer
presentations.

2.2  Determine solution fit

NetSolve will utilize a standard set of criteria included in Exhibit 1 in order
to determine the proper solution. If the solution is determined to fall outside
one of the bundles, NetSolve will forward the opportunity back to the DNAE to be
sent to his/her Data Network Consultant (DNC) for completion.


                        !*! NEED TO ATTACH EXHIBIT 1 !*!


2.3  Complete standard MNS pricing and design

NetSolve will complete an appropriate network design and pricing within 48 hours
for non-SNA offer bundles, and 96 hours for other offer bundles. The timing on
this deliverable is measured from the completion of the prospect interview. The
pricing includes quotes for management, equipment, cables, installation, and
maintenance. Equipment pricing will include terms indicated on the pre-
qualification form.

shall not be deemed exclusive and thereby contemplates that contracts may be
entered into between the Company and its officers and directors with respect to
indemnification of such persons; and

     WHEREAS, the Company believes that it is prudent and in the Company's best
interest to support and augment the protection afforded the Company's officers
and directors in this regard; and

     WHEREAS, Indemnitee and other officers and directors may not be willing to
serve as such without adequate protection and the Company desires to attract and
retain the services of highly qualified individuals, such as Indemnitee, to
serve as an officer and/or director of the Company and to indemnify its officers
and directors so as to provide them with the maximum protection permitted by law
as an inducement to their continued service to the Company.

     NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

     1.   Indemnification in General.  The Company shall indemnify and hold
harmless Indemnitee to the fullest extent permitted or authorized by Applicable
Law.  For purposes hereof the term "Applicable Law" shall mean Section 145 of
the General Corporation Law of the State of Delaware as in effect on the date
hereof and as hereafter amended (but in the case of such amendment, only to the
extent such amendment permits the Company to provide broader indemnification
rights than permitted prior to such amendment).

     2.   Additional Indemnity.  Subject only to the exclusions set forth in
Section 3 hereof, the Company shall further indemnify and hold harmless
Indemnitee:

          (a)  Against any and all expenses (including attorneys' fees),
     judgments, fines and amounts paid in settlement, actually and reasonably
     incurred by Indemnitee in connection with any threatened, pending or
     completed action, suit, or proceeding, whether formal or informal, or
     civil, criminal, administrative, legislative, arbitrative or investigative
     (including without limitation any action by or in the right of the Company)
     (hereinafter a "Proceeding") to which Indemnitee is, was or at any time
     becomes, a party, or is threatened to be made a party, by reason of the
     fact that Indemnitee is, was or at any time becomes, a director, officer,
     or agent of the Company or is or was or at any time serves at the request
     of the Company (which request need not be in writing) or on behalf of the
     Company as a director, officer, employee or agent of another corporation,
     partnership, joint venture, trust, employee benefit plan or other
     enterprise (hereinafter an "Enterprise"); and
<PAGE>

          (b)  Otherwise to the fullest extent as may be contractually provided
     to Indemnitee by the Company under Applicable Law consistent with any
     public policy limitations applicable thereto.

     3.   Limitations on Additional Indemnity.  No indemnity pursuant to Section
2 hereof shall be paid by the Company:

          (a)  for amounts indemnified by the Company other than pursuant to
     Section 2 of this Agreement;

          (b)  for amounts, if any, paid pursuant to any policies of directors
     and officers liability insurance maintained by the Company for the benefit
     of Indemnitee;

          (c)  with respect to remuneration paid to Indemnitee if it shall be
     determined by a final judgment or other final adjudication that such
     remuneration was in violation of law;

          (d)  on account of any suit in which judgment is rendered against
     Indemnitee for an accounting of profits made from the purchase and sale of
     Indemnitee of securities of the Company pursuant to the provisions of
     Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto
     or any similar provision of federal, state or local statutory law;

          (e)  on account of Indemnitee's conduct which is finally adjudged to
     have been knowingly fraudulent, deliberately dishonest or willful
     misconduct; or

          (f)  if a final adjudication by a court having jurisdiction in the
     matter shall determine that such indemnification is not lawful.

          (g)  for judgments, fines, and amounts paid in settlement incurred in
     a proceeding brought by or in the right of the Company.

     4.   Notification and Defense of Claims.  As soon as reasonably practicable
after the receipt by Indemnitee of notice of the commencement of any Proceeding,
Indemnitee will, if a claim in respect thereof is to be made against the Company
under this Agreement, notify the Company of the commencement of such Proceeding;
provided however that the omission to so notify the Company will not relieve the
Company from any liability which it may have to Indemnitee otherwise than under
this Agreement.  With respect to any such Proceeding as to which Indemnitee
notifies the Company of the commencement thereof;

          (a)  The Company shall be entitled to participate therein at its
     expense; and

          (b)  Except as otherwise provided herein, to the extent it may elect
     to do so, the Company (jointly with any other indemnifying party similarly
     notified) will be entitled to assume the defense thereof, with counsel of
     its own selection reasonably satisfactory to Indemnitee. After notice from
     the Company to Indemnitee of its election to assume the defense thereof,
     Company will not be liable to Indemnitee under this Agreement for any
     legal

                                       2
<PAGE>

     or other expenses subsequently incurred by Indemnitee in connection with
     the defense of such Proceeding other than as otherwise provided below.
     Indemnitee shall have the right to employ separate counsel in such
     Proceeding but the fees and expenses of such counsel incurred after notice
     from the Company of its assumption of the defense shall be at the expense
     of the Indemnitee unless (i) the Company has authorized Indemnitee to
     employ separate counsel and has agreed to assume the reasonable fees and
     expenses of such counsel; (ii) Indemnitee shall have reasonably concluded
     that there may be a conflict of interest between the Company and Indemnitee
     in the conduct of the defense of such Proceeding; or (iii) the Company
     shall not in fact have employed counsel to assume the defense of such
     Proceeding, in each of which cases the reasonable fees and expenses of
     counsel shall be at the expense of the Company.  The Company shall not be
     entitled to assume the defense of any Proceeding brought by or on behalf of
     the Company or as to which an Indemnitee shall have made the conclusion
     provided for in (ii) above.

          (c)  The Company shall not be liable to indemnify Indemnitee under
     this Agreement for any amounts paid in settlement of any Proceedings or
     claims effected without its prior written consent. The Company shall not
     settle any Proceeding or claim in any manner which might impose any
     liability, penalty or limitation on Indemnitee without Indemnitee's prior
     written consent. Neither the Company nor Indemnitee will unreasonably
     withhold their consent to any proposed settlement.

     5.   Payment In Advance.  The expenses incurred by Indemnitee in defending
any Proceeding shall be advanced by the Company at the request of the
Indemnitee.  The term "expenses" as used in this section shall include
attorney's fees and expenses that may be only arguably indemnifiable under the
governing law.  Any judgments, fines or amounts to be paid in settlement shall
also be advanced by the Company to Indemnitee upon request.  If it shall
ultimately be determined that Indemnitee was not entitled to be indemnified, or
was not entitled to be fully indemnified, Indemnitee shall repay to the Company
all amounts advanced, or the appropriate portion thereof, so advanced.

     6.   Right of Indemnitee to Bring Suit.  If a claim for indemnification or
a claim for an advance under this Agreement is not paid in full by the Company
within 90 or 15 days, respectively, after the Company has received a written
claim therefor by Indemnitee, Indemnitee may bring suit against the Company to
recover the unpaid amount of the claim.  If Indemnitee is successful in whole or
in part in such suit, Indemnitee shall also be paid the expense of prosecuting
such claim (including without limitation attorneys' fees).

     7.   Continuation of Indemnity.  All agreements and obligations of the
Company contained herein shall continue during the period Indemnitee is a
director, officer or agent of the Company (or is serving at the request of the
Company or on behalf of the Company, as a director, officer, employee or agent
of another Enterprise) and shall continue thereafter so long as Indemnitee shall
be subject to any possible Proceeding or claim by reason of the fact that
Indemnitee was a director, officer or agent of the Company or serving in any
other capacity referred to herein.

                                       3
<PAGE>

     8.   Nonexclusivity.  The indemnification and other rights provided by this
Agreement shall not be deemed exclusive of any other rights to which Indemnitee
may be entitled under any provision of statutory or common law, the Company's
Certificate of Incorporation, any Company By-Law, other agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in
Indemnitee's official capacity and as to action in another capacity while
occupying any of the positions or having any of the relationships referred to in
this Agreement, and shall continue after Indemnitee has ceased to occupy such
position or have such relationship.

     9.   Severability.  If any provision of this Agreement shall be held to be
invalid, illegal or unenforceable: (a) the validity, legality and enforceability
of the remaining provisions of this Agreement shall not be in any way affected
or impaired thereby; and (b) to the fullest extent possible, the provisions of
this Agreement shall be construed so as to give effect to the intent manifested
by the provision(s) held invalid, illegal or unenforceable.  Each section of
this Agreement is a separate and independent portion of this Agreement.  If the
indemnification to which Indemnitee is entitled as respects any aspect of any
claim varies between two or more sections of this Agreement, that section
providing the most comprehensive indemnification shall apply.

     10.  Modification and Waiver.  No supplement or amendment of this Agreement
shall be binding unless executed in writing by both parties hereto.  No waiver
of any of the provisions of this Agreement shall be binding unless executed in
writing by the person making the waiver nor shall such waiver constitute a
continuing waiver.

     11.  Notices.  All notices, requests, demands and other communications
hereunder shall be in writing and shall be deemed to have been duly given if:
(a) delivered by hand and receipted for by the party to whom said notice of
other communication shall have been directed; or (b) mailed by certified or
registered mail with postage prepaid, on the third business day after the date
on which it is so mailed:

Section 145 of the General Corporation Law of the State of Delaware and this
Agreement shall be governed by, and its provisions construed in accordance with,

     13.  Heirs, Successors and Assigns.  This Agreement shall inure to the
benefit of, and be enforceable by the Indemnitee's personal or legal

Agreement is binding on the successors and assigns of the Company. The Company
will require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business and/or
assets of the Company to expressly assume and agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform it if no such succession had taken place (the assumption by such
successor shall be by written agreement in form and substance reasonably
satisfactory to Indemnitee).

             this Section 5.4 shall be final, binding and conclusive. A notice

             such adjustment, the calculation method of such adjustment, and the
             change in price and the number of shares of Stock, or securities,

Section 12.       Special Provisions Applicable to Covered Participants

         If the Company shall become subject to Code Section 162(m), Awards to
Covered Participants shall be governed by the conditions of this Section 12 in
addition to the requirements of Sections 6 through 11 above. Should conditions
set forth under this Section 12 conflict with the requirements of Sections 6
through 11, the conditions of this Section 12 shall prevail.

         (a)      All Performance Criteria relating to Covered Participants for
                  a relevant Performance Period shall be established by the
                  Committee in writing prior to the beginning of the Performance
                  Period, or by such other later date for the Performance Period
                  as may be permitted under Section 162(m) of the Code.
                  Performance Criteria may include alternative and multiple
                  Performance Criteria and will be based on one or more of the
                  following business criteria: business or financial goals of
                  the Company, including absolute or relative levels of total
                  shareholder return, revenues, sales, net income, or net worth
                  of the Company, any of its Subsidiaries, divisions, business
                  units, or other areas of the Company.

         (b)      The Performance Criteria must be objective and must satisfy
                  third party "objectivity" standards under Code Section 162(m),
                  and the regulations promulgated thereunder.

         (c)      The Performance Criteria shall not allow for any discretion by
                  the Committee as to an increase in any Award, but discretion
                  to lower an Award is permissible.

         (d)      The Award and payment of any Award under this Plan to a
                  Covered Participant with respect to a relevant Performance
                  Period shall be contingent upon the attainment of the
                  Performance Criteria that are applicable to such Award. The
                  Committee shall certify in writing prior to payment of any
                  such Award that such applicable Performance Criteria have been
                  satisfied. Resolutions adopted by the Committee may be used
                  for this purpose.

         (e)      No Awards may be paid (in cash or in shares of Stock or a
                  combination thereof) to any Covered Participant under the Plan
                  pursuant to Sections 8, 9, 10 and 11 during any calendar year.

         (f)      The aggregate maximum number of shares of Stock subject to
                  Options and SARs made to any Covered Participant during any
                  calendar year shall be 100,000.

         (g)      All Awards to Covered Participants under this Plan shall be
                  further subject to such other conditions, restrictions, and
                  requirements as the Committee may determine to be necessary to
                  carry out the purposes of this Section 12.

Section 14. General Provisions

         14.1 Plan Term. The Plan was adopted by the Board on July 14, 1997, and

remit to the Company the amount of any taxes required to be withheld from such
payment in Common Stock, or, in lieu thereof, the Company may withhold (or the
Participant may be provided the opportunity to elect to tender) the number of
shares of Common Stock equal in Fair Market Value to the amount required to be
withheld.

         14.3 Awards. Each Award granted under the Plan shall be evidenced in a

         14.5 No Right to Employment. Neither the Plan, nor any Award made, or
              ----------------------
any other action taken, hereunder shall be construed as giving any Participant
or other person any right of employment or continued employment with the
Company.

         14.6 Rights as Stockholder. Subject to the terms and conditions of each
              ---------------------
particular Award, no Participant or Designated Beneficiary shall be deemed a

              ------------------------
governed, construed, interpreted and administered in accordance with the laws of
the State of Texas. In the event any provision of the Plan or any Agreement
shall be held invalid, illegal or unenforceable, in whole or in part, for any
reason, such determination shall not affect the validity, legality or
enforceability of any remaining provision, portion of provision or Plan overall,
which shall remain in full force and effect as if the Plan had been absent the
invalid, illegal or unenforceable provision or portion thereof.

         14.8 Amendment of Plan. The Committee or the Board of Directors may
              -----------------
amend, suspend, or terminate the Plan or any portion thereof at any time,
provided such amendment is made with stockholder approval if and to the extent
such stockholder approval is necessary to comply with any legal requirement,
including for these purposes any approval requirement which is a requirement for
the performance-based compensation exception under Code Section 162(m).

         14.9 Amendment of Award. In its sole and complete discretion, the
              ------------------
Committee may at any time amend any Award for the following reasons: (i)
additions and/or changes are made to the Code, any federal or state securities
law, or other law or regulations applicable to the Award; or (ii) any other
event not described in clause (i) occurs and the Participant gives his or her
consent to such amendment.

               -------------------------------------------------------------
acceptance of an applicable Award under this Plan, subject to the conditions of

               ------
elect to legend certificates representing Shares sold or awarded under the Plan,
to make appropriate references to the restrictions imposed on such Shares.


         14.12 Unfunded Plan. The Plan is intended to constitute an unfunded
               -------------
deferred compensation arrangement for a select group of management or highly

Mr. Harry S. Budow
5904 Kensington Drive
Plano, Texas 75093

Dear Harry,

On behalf of NetSolve Incorporated, I am pleased to offer you a position as Vice
President of Marketing, reporting to me. We would like you to commence work no
later than Monday, October 4, 1999, in our offices at 12331 Riata Trace Parkway,
Austin, Texas.

Your basic hours of work shall initially be 8:00 AM to 5:00 PM; however, your
job duties are professional in nature and therefore you are not eligible for
compensation in excess of forty (40) hours per week. It is anticipated that you
will work the number of hours necessary to accomplish the job for which you have
been hired, which may necessitate that you work more or different hours than
those described. The salary for this position is currently $16,667 per month.
Pay periods currently end on the 15th and the last day of each month. Your
salary and compensation level will be reviewed annually.

In addition to salary, the Company also offers certain employee benefits,
including group medical and dental insurance, 401(k) Plan, 125 Cafeteria Plan,
four weeks of paid vacation annually and equity in the Company. You will become
eligible for these benefits under, and subject to, the plans offered by the
Company on your date of hire. As the Company is committed to an ongoing review
of its benefits and policies, these items can vary in the future and are, at all
times, subject to the provisions of the documents describing such benefits and
policies.

It is mutually understood and agreed that, should your employment be terminated
by NetSolve prior to your first anniversary, other than for "cause," you shall
be entitled to receive salary continuance for 12 months from the date of
termination. Following your first anniversary, during the time you are employed
by NetSolve or its successors, you will be entitled to receive salary
continuance for 6 months under the same conditions as described immediately
above. Termination of employment shall be for "cause" if in the reasonable
opinion of NetSolve's President and CEO you:

     .    breach or neglect the duties which you are required to perform;
     .    commit any material act of dishonesty, fraud, theft,
          misrepresentation, or other act of moral turpitude;
     .    are guilty of gross carelessness or misconduct;
     .    fail to obey the lawful direction of your management;
     .    or act in any way that results in direct, substantial, and adverse
          effect on NetSolve's reputation.

Harry S. Budow                                                               2
June 17, 1999


You will be issued Stock Options, given ratification by the Board of Director's,
to purchase 100,000 shares of NetSolve Incorporated common stock pursuant to the
Company's Stock Option Plan. The actual grant of options will be subject to
Board of Director approval. Your option exercise price will be the fair market
value of the Company's common stock at the date of the grant, and your
participation in the Company's Stock Option Plan is subject to the provisions of
that plan. In addition, we will recommend to the Board that in the event
NetSolve is acquired and/or merged (where NetSolve is not the surviving entity)
in the first twelve months of your employment, the Board will accelerate your
vesting schedule to a minimum of 50%.

In order to assist you with your relocation to Austin, NetSolve will make a one
time payment to you of $100,000. In addition, we will provide you with the use
of NetSolve's apartment for a minimum of three months. You will be responsible
for any state or federal income tax consequences with respect to this payment
and if you should use the apartment. Should you terminate employment prior to
completing twelve months of service (unless terminated by NetSolve other than
for cause), you will be required to refund this amount on a prorated basis.

All offers of employment made by NetSolve are contingent upon the following:

     .    You are able to establish that you are authorized to work in the
          U.S.A. by the third day following your hire date; and
     .    You agree to and we receive satisfactory results on a background check
          of your education, work, driving, and criminal history; and
     .    You sign the NetSolve Proprietary Information and Inventions
          Agreement.

As with all our employees, if you should accept and then change your mind later,
you can terminate your employment at any time for any or no reason, as can the
Company, it being understood that your employment with the Company will be on an
"at will" basis.

I am sincerely happy that you have joined our team, and I look forward to
working with you.

If you agree to the terms of this letter, please sign below.

Sincerely,

/s/ Craig S. Tysdal

Craig S. Tysdal
President and CEO




I accept your position and acknowledge that it is conditioned upon my
establishing authorization to work in the U.S.A., agreeing to and receiving a
satisfactory background check, and signing of the NetSolve Proprietary
Information and Inventions Agreement. I further acknowledge that there were
no promises of stock, stock options, bonuses, guaranteed raises, promotions,
review dates, pay in lieu

of notice or severance pay or other inducements to my acceptance thereof other

constitute a promise or contract of continued employment and that both the
Company and I may, at any time, terminate my employment for any or no reason.

                       NONQUALIFIED STOCK OPTION AGREEMENT


           THIS NONQUALIFIED STOCK OPTION AGREEMENT (the "Agreement) is made and
entered into as of this 13th day of April, 1999, by and between NETSOLVE(SM)
INCORPORATED, a Delaware corporation (the "Company"), and
______________________, a director of the Company ("Optionee")

           WHEREAS, the Company desires, by affording Optionee an opportunity to
purchase shares of its Common Stock, $.01 par value per share (the "Common
Stock"), as hereinafter provided, to carry out the purposes of the Company's
Long-Term Incentive Compensation Plan, as amended (the "Plan");

           NOW, THEREFORE, in consideration of the covenants herein set forth,
the parties hereto have agreed and do hereby agree as follows:

           1. Grant of Option. The Company hereby grants to Optionee, pursuant
              ---------------
to the Plan, the terms and provisions of which are incorporated herein by
reference, an option (the "Option") to purchase all or any part of 15,000 shares
of the Common Stock of the Company on the terms and conditions herein set forth.

           2. Option Price. The Option Price of each share of Common Stock
              ------------
subject to this Option shall be $9.00 per share. Full payment for shares
purchased upon exercise of this Option shall be made in cash, cashier's check or
by delivery of previously owned shares of Common Stock (not subject to any
security interest or pledge) or partly in cash or such check and partly in such
stock. No shares may be issued until full payment of the Option Price therefor
has been made.

           3. Term of Option. The term of the Option shall be for a period of
              --------------
ten (10) years from the Date of Grant, subject to earlier termination or
cancellation as provided herein and in the Plan.

           4. Exercise of the Option. This Option shall be exercisable in full
              ----------------------
or in part at any time, and from time to time, during the term hereof. No
fractional shares may be issued pursuant to the exercise of this Option.
Furthermore, the exercise of this Option shall be subject to the condition that
if at any time the Company shall determine in its sole discretion that the
satisfaction of withholding tax or other withholding liabilities, or that the
listing, registration, or qualification of any shares otherwise deliverable upon
such exercise upon any national securities exchange or under any state or
federal law, or that the report to, or consent or approval of, any regulatory
body, is necessary or desirable as a condition of, or in connection with, such
exercise or the delivery or
<PAGE>

purchase of shares pursuant hereto, then in any such event, such exercise shall
not be effective unless such withholding, listing, registration, qualification,
report, consent or approval shall have been effected or obtained free of all
conditions not acceptable to the Company.

           5. Notice of Election. Subject to the terms and conditions hereof,
              ------------------
Optionee may exercise this Option by delivering written notice to the President
or the Secretary of the Company in person or by registered or certified mail,
postage prepaid. Such notice shall state the election to partially or totally
exercise this Option and the number of shares in respect of which it is being
exercised, and shall be signed by Optionee. Such notice shall be accompanied by
payment as provided for hereinbefore, in which event, the Company shall deliver
a certificate or certificates, as may be requested by Optionee, representing
such shares as soon as practicable after the notice and payment shall be
received. The certificate or certificates for the shares as to which the Option
shall have been exercised shall be registered as designated in the notice. In
the event the Option shall be exercised, pursuant to Paragraph 8 hereof, by any
person or persons other than the Optionee, such notice shall be accompanied by
proof deemed appropriate by the Committee of the right of such person or persons
to exercise the Option. All shares that shall be purchased upon the exercise of
this Option as provided herein shall be fully paid and non-assessable.

           6. Non-Transferability. During the lifetime of Optionee, this Option
              -------------------
shall be exercisable only by Optionee. This Option shall not be assignable or
transferable by Optionee, voluntarily or by operation of law, other than by will
or by the laws of descent and distribution. Neither this Option nor the shares
covered hereby shall be pledged or hypothecated in any way. Neither this Option
nor the shares covered hereby shall be subject to execution, attachment, or
similar process except with the prior written consent of the Board.

           7. Termination of Directorship. In the event that Optionee shall, at
              ---------------------------
any time hereafter, cease to be a director of the Company for any reason other
than Optionee's death, the Option may be exercised, to the extent of the shares
with respect to which the Option could have been exercised by Optionee on the
date of such termination prior to the earlier of the date of its expiration or:
(i) thirty (30) days after the date of such termination in the case of
termination for any reason other than retirement, permanent disability or death;
or (ii) three (3) months after the date of such termination, in the case of
termination by reason of retirement or permanent disability.

           8. Death of Optionee. If Optionee dies prior to the termination of
              -----------------
Optionee's right to exercise the Option in accordance with the provisions hereof
without having totally exercised the Option, the Option may be exercised, to the
extent of the shares with respect to which the Option could have been exercised
by Optionee on the date of Optionee's death, by the Optionee's estate or by the
person who acquires the right to exercise the Option by bequest, inheritance, or
by reason of the death of the Optionee, provided the Option is exercised prior
to the date of its expiration or one (1) year from the date of the Optionee's
death, whichever occurs first.

           9. Adjustments. The number of shares of Common Stock covered by this
              -----------
Option and the Option Price may be adjusted to reflect, as deemed appropriate by
the Board in its discretion, any stock dividend, stock split, reverse stock
split, share combination, exchange of shares, recapitalization, merger,
consolidation, separation, reorganization, liquidation or the like of or by the

                                      -2-
<PAGE>

Company. Decisions by the Committee as to what adjustments shall be made, and
the extent thereof, shall be final, binding and conclusive on Optionee.

           10. No Other Rights or Obligations. Optionee shall have no rights by
               ------------------------------
reason of this Option as a stockholder with respect to any shares covered hereby
until the date of the issuance of one (1) or more stock certificates to him for
such shares pursuant to the due exercise of the Option. The granting of this
Option does not confer on Optionee any right to continue to serve on the board
of directors of the Company for any period or any additional rights other than
as expressly provided for herein.

           11. Subject to Plan. This Option is subject to all of the terms and
               ---------------
conditions of the Plan (as it may be amended from time to time). In the event of
any conflict between such terms and conditions and those set forth herein, the
terms of the Plan shall govern and be determinative. Unless otherwise defined
herein, each of the capitalized terms used herein shall have the meaning given
to such term in the Plan.

           12. Nonqualified Stock Option. This Option is not intended to qualify
               -------------------------
as an "incentive stock option" under the relevant provision of the Code, and
shall, therefore, not be construed as an incentive stock option. Nothing in this
Agreement nor in the Plan shall be deemed to be or interpreted as a
representation, guarantee or other undertaking on the part of the Company as to
the character of the Option for tax purposes. Optionee understands that he/she
should consent with his or her own tax and/or financial advisor with respect to
the effect of this Option.

           13. Amendment. The Company shall have the right, without the consent
               ---------
or approval of the Optionee, to amend, modify, limit or terminate this Option or
any term or provision hereof; provided, however, that no such action may be
taken by the Company, not expressly provided for herein or in the Plan, in
derogation of the vested rights of the Optionee, without the consent or approval
of the Optionee. Any such action by the Committee shall be final and binding on
Optionee.

           14. Shareholder's Agreement. The exercise of this Option is expressly
               -----------------------
conditioned upon the prior or contemporaneous execution by the Optionee and the
Company of a Shareholder's Agreement, as provided in the Plan. All rights of the
Optionee and Optionee's heirs, successors and assigns shall be determined by
such agreement and Optionee and Optionee's heirs, successors and assigns shall
be bound thereby. The shares of Common Stock issued pursuant to the exercise
hereof shall not be deemed to be "fully vested stock options" and shall be
subject to the repurchase rights as provided in such Shareholder's Agreement.

                            SHAREHOLDER'S AGREEMENT


           THIS SHAREHOLDER'S AGREEMENT (the "Agreement") is made as of the 13th
day of April, 1999, by and between NETSOLVE(SM) INCORPORATED, a Delaware
corporation (the "Company"), and ______________________ (the "Purchaser").

           WHEREAS, the Purchaser has been granted an option to purchase shares
of Common Stock of the Company under the Company's Long-Term Incentive
Compensation Plan (the "Plan"); and

           WHEREAS, the Purchaser and the Company acknowledge that they are
entering into this Agreement in accordance with the provisions of the Plan and
that certain Series B Preferred Stock Purchase Agreement (the "Stock Purchase
Agreement"), dated as of October 19, 1992, as amended, by and among the Company
and the Investors (as defined therein);

           NOW, THEREFORE, IT IS HEREBY AGREED:

           1. Sale and Purchase of Shares. Pursuant to the terms and conditions
              ---------------------------
of this Agreement, upon exercise of Purchaser's option, the Purchaser shall
purchase, and the Company shall sell to Purchaser, 15,000 shares of Common Stock
of the Company (the "Shares") for a cash consideration of $9.00 per share.

           2. Company's Right to Repurchase. The Shares shall be subject to the
              -----------------------------

          (a) If the Purchaser should cease to be a director of the Company, for
     any reason, the Company (or, as provided in (c) below, its designee) shall
     have the right to repurchase from the Purchaser, or the Purchaser's
     personal representative, as the case may be, all of the Shares subject to
     the Repurchase Right. The starting date for determination of the percentage
     of the Shares which are subject to the Repurchase Right shall be the date

          (c) Within sixty (60) days after the later of the effective date upon
     which Purchaser ceases to be a director of the Company, upon notice to
     Purchaser specifying the time, place and date for settlement, the Company
     (or, to the extent the Company is legally prohibited from exercising such
     right, its designee) shall repurchase from the Purchaser, in cash, at
     Purchaser's original purchase price per share as set forth in Paragraph 1
     above, the Shares which are subject to the Repurchase Right. If the Company
     is prohibited by law from fully exercising, or the Company (or its
     designee) fails to fully exercise this Repurchase Right within such sixty
     (60) day period, the Repurchase Right shall expire as to all Shares.

     3.   Rights as Stockholder; Escrow.
          -----------------------------

          (a) Subject to the terms and conditions of this Agreement, Purchaser
     shall have all of the rights of a stockholder of the Company with respect
     to the Shares from and after the date of issuance of the Shares until
     repurchase or other disposition of the



                                      -2-
<PAGE>

     Shares as provided for herein. At all times after the date of this
     Agreement, whenever submitted to the stockholders of the Company for vote
     thereon, Purchaser agrees to vote the Shares in accordance with the terms
     of Section 8 of the Stock Purchase Agreement (the terms of which, as
     amended from time to time, are incorporated herein by reference) as though
     he/she were a party thereto.

          (b) Purchaser shall deliver all certificates representing the Shares
     to the Secretary of the Company for safekeeping. Each such certificate
     shall be accompanied by a duly executed stock power authorizing any officer
     to effect the transfer of such Shares on the books of the Company in
     accordance with the terms of this Agreement. If Purchaser so requests, such
     Secretary will deliver to Purchaser certificates representing such number
     of Shares as are not then subject to the Repurchase Right. Following the
     exercise, or lapse without exercise, of the Repurchase Right, the Company
     will direct its Secretary to deliver to Purchaser a certificate(s)
     representing the aggregate number of Shares, if any, not repurchased by the
     Company.

     4.       Stock Splits, Recapitalizations, Etc. If during the term of the
              ------------------------------------
Repurchase Right:

              (a) there is any stock dividend, stock split, reverse stock split,
     reorganization, reclassification, recapitalization, spin-off or other
     change in the character or amount of the outstanding securities of the
     Company; or

              (b) there is any consolidation, merger, or sale of all, or
     substantially all, of the assets of the Company;

then, in such event, any and all new, substituted or additional securities or
property to which the Purchaser is entitled by reason of ownership of the Shares
shall be immediately subject to this Agreement and be included in the term
"Shares" for all purposes of this Agreement, and the repurchase price per share
specified in Paragraph 2(c) shall be appropriately adjusted by the Board of
Directors of the Company.

     5.       Purchase of Additional Stock. If the Purchaser at any time after
              ----------------------------
the date of this Agreement acquires any capital stock of the Company, in
addition to that described in Paragraphs 1 and 4 above (other than capital stock
acquired on the open market or from an unrelated third party, and capital stock
acquired from the Company which the Board of Directors of the Company, in its
discretion, expressly designates as not subject to this Agreement), or any
options, rights or warrants therefor ("Additional Stock"), such Additional Stock
shall be immediately subject to this Agreement and included in the term "Shares"
for all purposes of this Agreement; provided, however, that:

              (a) the repurchase price per share of such Additional Stock shall
     be the purchase price paid or to be paid by the Purchaser therefor;

                                      -3-
<PAGE>

          (b) any such Additional Stock purchased pursuant to a vested option
     shall be deemed to be fully vested and not subject to the Repurchase Right;
     and

          (c) the "Vesting Commencement Date" for purposes of the Repurchase
     Right shall be the date of purchase by, or issuance to, Purchaser of such
     Additional Stock unless otherwise specified by the Company's Board of
     Directors at the time of such purchase or issuance.

     6.   Right of First Refusal. Shares subject to the Repurchase Right may
          ----------------------
not be transferred. Before any Shares held by the Purchaser and not subject to
the Repurchase Right may be sold or otherwise transferred (including, but not
limited to, any transfer by operation of law and any transfer at death or by
inheritance, but excluding a transfer described in Paragraph 6(e) hereof), such
Shares shall first be offered to the Company in the following manner:

          (a) Purchaser shall deliver to the Company a notice (the "Notice")
     stating (i) his bona fide intention to sell or otherwise transfer such
     Shares; (ii) the number of Shares to be transferred; (iii) the name of the
     proposed transferee; and (iv) the price or other consideration for which
     Purchaser proposes to transfer the Shares.

          (b) At any time within sixty (60) days after receipt of the Notice,
     the Company, upon notice to Purchaser specifying the time, place and date
     for settlement, may elect to purchase all of the Shares specified in the
     Notice at the price per share specified therein, or if no price is
     specified, at the fair market value thereof as determined in good faith by
     the Company's Board of Directors.

                                      -4-
<PAGE>

          (c) The Company's right of first refusal provided for in this
     Paragraph 6 shall not be assignable, except that if the Company does not,
     for any reason, exercise its right of first refusal within thirty (30) days
     after receipt of the Notice, the Company hereby assigns such right as of
     that date to the Investors, or their heirs, executors, guardians,
     successors and assigns, who are then holders of the Company's Preferred
     Stock or Common Stock of the Company into which such stock has been
     converted. The Company may also, by written agreement, assign such right
     (on a pro rata basis) to subsequent purchasers of the Company's Preferred
     Stock. The right shall be exercisable by each such assignee, upon notice to
     Purchaser specifying the time, place and date for settlement, with respect
     to the number of Shares subject to such right in the proportion which the
     number of shares of Common Stock owned (or which would be owned upon
     conversion of the Preferred Stock) by such assignee at the time of
     exercise, bears to the total number of shares of Common Stock so owned or
     deemed to be owned by all such assignees. Each such assignee which
     exercises its right to purchase all of the Shares purchasable by it
     hereunder may, in addition, exercise such right as to the Shares not
     purchased by other assignees hereunder, pro rata based upon the number of
     shares of Common Stock so owned (or deemed to be owned) by each assignee
     exercising its right hereunder. The sale by Purchaser to the Company or its
     assignees shall be consummated within sixty (60) days after receipt by the
     Company of the Notice.

          (d) If all of the Shares to which the Notice refers are not purchased
     by the Company or such assignees within such sixty (60) day period, then
     such right of first refusal shall terminate and Purchaser may sell such
     Shares to any person named in the Notice at the price specified therein, or
     at a higher price, provided that such sale or transfer is consummated
     within ninety (90) days of the date of the Notice to the Company, and
     provided further, that any such sale is in accordance with all the terms
     and conditions hereof. If the Purchaser does not consummate the sale or
     transfer within such 90-day period, the right of first refusal provided
     herein shall be deemed to be revived with respect to such Shares and no
     sale or transfer shall be effected without first offering the Shares in
     accordance herewith.

          (e) There shall be excepted from this right of first refusal any gift
     or donation to a member of Purchaser's family, or to a trust established
     for the benefit of Purchaser or a member or members of his family, provided
     that any such transfer to a child who is then under twenty-one (21) years
     of age must be conditioned upon the Purchaser retaining and reserving for
     himself the right to do any act with respect to the transferred Shares on
     behalf of such transferee that is permitted, authorized or required by this
     Agreement. For purposes hereof, the term "family" shall mean the spouse,
     natural or adopted children and other lineal descendants, parents,
     parents-in-law, brothers, sisters, nephews, and nieces of Purchaser.

                                      -5-
<PAGE>

          (f) Notwithstanding the above, neither the Company nor its assignees
     shall have any right under this Paragraph 6 at any time subsequent to the
     closing of a bona fide, firm commitment underwritten public offering of the
     Common Stock of the Company pursuant to a Registration Statement on Form
     S-1, or its then equivalent, declared effective under the Securities Act of
     1933, as amended.

     7.   Investment Representations of Purchaser. Purchaser hereby
          ---------------------------------------
represents and warrants that he is acquiring the Shares with his own funds for
investment for an indefinite period for his own account, not as a nominee or
agent, and not with a view to the sale or distribution of any part thereof, and
that he has no present intention of selling, granting participation in, or
otherwise distributing the same, but subject, nevertheless, to any requirement
of law that the disposition of his property shall at all times be within his
control. Purchaser further represents that he does not have any contract,
undertaking, agreement or arrangement to sell, transfer, or grant participations
to any third person, with respect to any of the Shares.

     Purchaser represents that he is able to fend for himself in the transaction
contemplated by this Agreement, has such knowledge and experience in financial
and business matters as to be capable of evaluating the merits and risks of his
investment, has the ability to bear the economic risks of his investment and has
been furnished with and has had access to such information as would be made
available in the form of a registration statement, together with such additional
information as is necessary to verify the accuracy of the information supplied
and to have all questions answered by the Company.

     Purchaser understands that the Shares have not been registered under the
Securities Act of 1933, as amended (the "Act"), on the ground that the sale
provided for in this Agreement is exempt pursuant to Section 3(b) or 4(2) of the
Act, and that the Company's reliance on such exemption is predicated on his
representations set forth herein.

     Purchaser understands that if the Company does not register with the
Securities and Exchange Commission pursuant to Sections 12 or 15 of the
Securities Exchange Act of 1934 or if a registration statement covering the
Shares (or a filing pursuant to the exemption from registration under Regulation
A of the Act) under the Act is not in effect when he desires to sell the Shares,
he may be required to hold the Shares for an indeterminate period. The Purchaser
also acknowledges that he understands that any sale of the Shares which might be
made by him in reliance upon Rule 144 under the Act may be made only in limited
amounts in accordance with the terms and conditions of that Rule and that he may
not be able to sell the Shares at the time or in the amount he so desires.
Purchaser is familiar with Rule 144 and understands that the Shares constitute
"restricted securities" within the meaning of that Rule.

     Purchaser agrees that in no event will he make a disposition of any of the
Shares unless and until (a) he shall have notified the Company of the proposed
disposition and shall have furnished the Company with a statement of the
circumstances surrounding the proposed disposition, and (b) he shall have
furnished the Company with an opinion of counsel satisfactory to the Company to
the effect that (i) such disposition will not require registration of such
Shares

                                      -6-
<PAGE>

under the Act, or (ii) that appropriate action necessary for compliance
with the Act has been taken, or (c) the Company shall have waived, expressly and
in writing, its rights under clauses (a) and (b) of this subparagraph. The
Company shall be under no obligation to register such Shares.

     8. Restrictive Legends. All certificates representing any Shares subject to
        -------------------
the provisions of this Agreement shall have endorsed thereon the following
legends:

          (a) "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE
     TERMS AND CONDITIONS OF A CERTAIN SHAREHOLDER'S AGREEMENT WHICH, AMONG
     OTHER THINGS, INCLUDES A RIGHT OF REPURCHASE OF THESE SECURITIES, A RIGHT
     OF FIRST REFUSAL ON THE SALE OF THE SECURITIES AND REQUIRES THAT THESE
     SECURITIES BE VOTED AS THEREIN PROVIDED. COPIES OF THE AGREEMENT MAY BE
     OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE CORPORATION."

          (b) "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933. THESE SECURITIES HAVE BEEN
     ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO DISTRIBUTION OR RESALE, AND
     MAY NOT BE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT COVERING
     SUCH SHARES UNDER THE SECURITIES ACT OF 1933, OR PURSUANT TO RULE 144 UNDER
     THE ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT
     REGISTRATION IS NOT REQUIRED UNDER SUCH ACT."

          (c) Any legend required to be placed thereon by applicable state
     securities laws.

     9.   No Obligation to Transfer. The Company shall not be required (i) to
          -------------------------
transfer on its books any Shares which shall have been sold or transferred in
violation of any of the provisions set forth in this Agreement, or (ii) to treat
as owner of such Shares or to accord the right to vote as such owner or to pay
dividends to any transferee to whom such Shares shall have been so transferred.

     10. Further Assurances. The parties agree to execute such further
         ------------------
instruments and to take such further action as may reasonably be necessary to
carry out the intent of this Agreement.

     11. Governing Law. This Agreement shall be construed, governed and enforced
         -------------
in accordance with the laws of the State of Texas, except to the extent the
General Corporation Law of the State of Delaware is applicable.

<PAGE>

     12. Entire Agreement. This Agreement constitutes the entire agreement
         ----------------
of the parties with respect to the subject matter hereof. This Agreement may
only be amended with the written consent of the parties hereto and the written
consent of the Investors, or their respective successors or assigns, who are
then holders of at least a majority of the Preferred Stock or Common Stock of
the Company into which such Preferred Stock has been converted; and no oral
waiver or amendment shall be effective under any circumstances whatsoever.

     13. Binding Effect. This Agreement shall be binding upon and inure to
         --------------
the benefit of the parties hereto and their respective successors, heirs,
executors, administrators, guardians and personal representatives. Nothing in
this Agreement shall be construed to give any person or entity other than the
parties hereto and their respective successors any legal or equitable right,
remedy or claim under this Agreement.

     14. Headings. Headings of the several sections of this Agreement are
         --------
inserted for convenience only and shall not control or affect the meaning or
construction of any of the provisions hereof.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the day and year first above written.
