  Because this is only a summary, it does not contain all the information that
may be important to you. You should read the entire Prospectus, especially
"Risk Factors" and the Consolidated Financial Statements and Notes, before
deciding to invest in shares of our common stock.
 
                                    NETSOLVE
 
OUR BUSINESS:     NetSolve offers a range of remote network management and
                  security services that allow companies to selectively
                  outsource, or "out-task," activities relating to the design,
                  implementation and management of their wide area networks
                  ("WANs") and local area networks ("LANs"). Our services are
                  designed to increase network reliability and up-time, reduce
                  overall network costs, and simplify timely migration to new
                  technologies.
 
OUR CONCEPT:      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 WANs across multiple sites, but too small to afford
                  the information technology ("IT") personnel necessary to
                  manage and secure their networks. Facing rapid advances in
                  technology and a continuing shortage of IT professionals,
                  these companies are beginning to turn to third-party service
                  providers for network management and security solutions.
 
OUR SERVICES:     Our network management services address all or selected parts
                  of the full life cycle of network management, which consists
                  of the following elements:
 
                    . design            . monitoring        . reporting
 
                    . configuration     . fault diagnosis   . upgrading
 
                    . implementation    . fault resolution  . 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 provide around-the-
                  clock remote security services for networks' Internet and
                  intranet perimeter points.
 
OUR CUSTOMERS:    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 375 middle market companies currently use our services
                  to manage more than 4,800 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 52% of our total revenues in our
                  fiscal year ended March 31, 1998.
 
OUR OFFICES:      Our executive offices are located at 12331 Riata Trace
                  Parkway, Austin, Texas 78727. Our telephone number is (512)
                  340-3000.

                                 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 are uncertain about the future of our
business and, in preparing this Prospectus, have made a number of assumptions
and projections. We generally use words like "expect," "believe" and "intend"
to indicate these assumptions and projections. Our assumptions and projections
could be wrong for many reasons, including the reasons discussed below.
 
LIMITED           Although NetSolve began operating in 1987, we did not
OPERATING         introduce our first remote network management service until
HISTORY; PAST     the quarter ended March 31, 1994. From inception through
LOSSES            November 1996, we generated substantially all of our
                  revenues from our data transport business, which we sold in
                  December 1996. Thus, our track record in the remote network
                  management services business is short, and it is difficult
                  to predict our future revenues and operating results. We
                  incurred substantial net losses from continuing operations
                  through the quarter ended June 30, 1998. We had operating
                  losses from continuing operations of $3.2 million in the
                  fiscal year ended March 31, 1998 and $0.2 million in the six
                  months ended September 30, 1998. As the result of
                  accumulated operating losses, our accumulated deficit at
                  September 30, 1998 totaled $37.4 million. Our ability to
                  operate profitably depends on increasing sales of our
                  services while maintaining sufficient gross profit margins.
                  We must, among other things:
 
                     . maintain satisfactory relationships with AT&T, which
                       is 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 remote network management
                       services;
 
                     . maintain reliable, uninterrupted service from our
                       Network Management Center 24 hours per day, seven
                       days per week;
 
                     . respond effectively to competitive pressures; and
 
                     . maintain reasonable levels of development and selling
                       costs.
 
                  Our ability to operate profitably also depends upon a number
                  of circumstances outside our control, including the extent
                  to which:
 
                     . our competitors develop solutions that compete with
                       our services;
 
                     . the number of qualified IT professionals increases
                       without a significant increase in compensation;
 
                     . equipment manufacturers introduce new, more
                       technologically advanced equipment and related
                       software; and
 
                     . our marketing partners dedicate resources or give
                       priority to reselling our services.
 
                  As a result, we cannot assure you that we will operate
                  profitably on a quarterly or annual basis. For more
                  information, see "Selected Consolidated Financial Data" and
                  "Management's Discussion and Analysis of Financial Condition
                  and Results of Operations."

DEPENDENCE ON     Sales to AT&T, which resells our services to its customers,
AT&T              accounted for 52% of our total revenues in the fiscal year
                  ended March 31, 1998. We expect that services sold to AT&T
                  will continue to generate a substantial percentage of our
                  revenues. Our strategy is to develop more end users outside
                  of our AT&T relationship by increasing the number of
                  telecommunications carriers, Internet service providers and
                  data networking value-added resellers that market our
                  services. We expect, however, that sales to AT&T will
                  comprise an even higher percentage of our revenues during
                  the latter half of fiscal 1999 and at least a significant
                  portion of fiscal 2000. As a result, we cannot be sure that
                  we will be successful in reducing our dependence on AT&T.
 
                  Our existing agreements with AT&T can be canceled by AT&T at
                  any time for reasons beyond our control. These agreements do
                  not prohibit AT&T from marketing other products and services
                  that compete with our services. 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. For more information, see
                  "Management's Discussion and Analysis of Financial Condition
                  and Results of Operations--Overview--Revenues" and
                  "Business--Relationship with AT&T."
 
FLUCTUATIONS IN   Our revenues and results of operations are difficult to
QUARTERLY         predict and may fluctuate significantly from quarter to
PERFORMANCE       quarter. If either our revenues or results of operations
                  fall below the expectations of investors or public market
                  analysts, the price of the common stock could fall
                  dramatically.
 
                  Our revenues are difficult to forecast 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;
 
                     . 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;
 
                     . potential end users may delay the installation of
                       equipment or the purchase of our services, and as a
                       result, we may have difficulty determining when a
                       potential customer will purchase our services;
 
                     . we expect to encourage end users to purchase
                       equipment from other sources, and we therefore
                       anticipate that our revenues from equipment sales
                       will decline from quarter to quarter as we seek to
                       manage our mix of revenues by limiting discounts on
                       equipment;
 
                     . 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;
 
                     . we may not be able to develop new or improved
                       services as rapidly as they are needed;

                     . some of our employees may terminate their employment
                       with NetSolve, resulting in an increase in our
                       recruiting and training costs and a decrease in the
                       level and quality of services that we can provide;
 
                     . our competition may offer better or cheaper services,
                       forcing us to lower prices or to spend more to market
                       our services; and
 
                     . either we or other service providers may suffer from
                       network service interruptions that cause us to make
                       payments under the contractual performance guarantees
                       that we offer our customers.
 
                  Most of our expenses, particularly employee compensation and
                  rent, are relatively fixed. As a result, variations in the
                  timing of revenues could cause significant variations in
                  results of operations from quarter to quarter and could
                  result in quarterly losses.
 
                  We believe our future operating results may vary by season:
 
                     . Our bookings may be slower during the months of July
                       and August due to the vacation schedules of our end
                       users and our sales and marketing employees. This 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 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 the 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. For
                  more information, see "Management's Discussion and Analysis
                  of Financial Condition and Results of Operations--Quarterly
                  Results of Operations."
 
NEWNESS OF        Our long-term viability depends significantly upon the
MARKET FOR OUR    acceptance and use of remote network management services by
SERVICES          mid-sized companies. The market for remote network
                  management services is new and rapidly evolving. This 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 IT
                  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.
 
UNCERTAINTIES     We expect to rely increasingly on resellers such as
OF RESELLER       telecommunications carriers, Internet service providers and
CHANNEL           data networking value-added resellers to market our
                  services. Our failure to establish these alternative sales
                  channels would seriously damage our business. We have
                  limited experience in managing sales through resellers. We
                  have only recently begun to develop these sales channels,
                  and we have 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 do not restrict the resellers' development or
                  sale of competitive services. We have very little control
                  over these resellers, and we cannot be sure that they 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 and software 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.
 
DEPENDENCE ON     Sales of our ProWatch for WANs and similar WAN services
WAN SERVICES;     accounted for 98% of our recurring network management
NEED TO DEVELOP   services revenues in both the fiscal year ended March 31,
AND SELL          1998 and the six months ended September 30, 1998. We expect
ADDITIONAL        that these WAN services will continue to generate
SERVICES          substantially all of our revenues for the foreseeable
                  future. Our success therefore depends directly on continued
                  market acceptance of our WAN services, as well as our
                  ability to introduce enhanced versions of these services
                  that make these services more efficient and economical. Our
                  revenues from these WAN services will suffer if there is a
                  decrease in the market demand for the Frame Relay-based
                  networks and other switched networks that underlie WANs. In
                  addition, competitive pressures or other factors that
                  adversely affect sales of our WAN services or that cause
                  significant decreases in the prices of our WAN services
                  could seriously damage our business.
 
                  Our future financial performance will depend in part on our
                  ability to develop, introduce and sell new and enhanced
                  remote network management services other than WAN 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 remote
                  network management services for 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 have experienced delays in
                  developing new services in the past and may experience
                  similar delays in the future. We cannot assure you that
                  future technological or industry developments will be
                  compatible with our business strategy
 
                                      10

                  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 services could seriously
                  damage our business.
 
DEPENDENCE ON     Our future success depends to a significant degree on the
SERVICES OF       skills, experience and efforts of our executive officers,
CURRENT CHIEF     particularly Craig S. Tysdal, the President and Chief
EXECUTIVE         Executive Officer of NetSolve. Mr. Tysdal has led NetSolve
OFFICER           during our transition from the data transport business to
                  the remote network management field. He was our principal
                  sales executive during the fiscal year ended March 31, 1998,
                  and he continues to be 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. For more information,
                  see "Management--Executive Officers and Directors."
 
LIMITED SUPPLY    We derive all of our revenues from remote network management
OF QUALIFIED IT   services and related sales of equipment. These services can
PROFESSIONALS     be extremely complex, and in general only highly qualified,
                  highly trained IT professionals have the necessary skills to
                  develop and provide these services. In order to continue to
                  staff our current and future bookings, 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
                  marketing partners and companies throughout the 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 help us. We do not enter into employment agreements
                  requiring these employees to continue in our employment for
                  any period of time.
 
COMPETITION       We face competition from different sources. Currently, we
                  compete principally with potential end users' and resellers'
                  internal development 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 such as NetSolve. In order for us
                  to compete effectively with internal solutions, we must
                  establish one or more of the following competitive
                  advantages:
 
                     .quality of service;
 
                     .price;
 
                     .functionality;
 
                     .product reputation; and
 
                     .quality of support.
 
                  If the market for network management services grows as we
                  expect, we believe this market will be highly competitive.
                  Competition is likely to increase significantly as new
                  companies enter the market and current competitors expand
                  their service and
 
                                      11
<PAGE>
 
                  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. For more information, see "Business--Competition."
 
SYSTEM FAILURE    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 remote network
                  management services are provided from our Network Management
                  Center, which is located at a single site. We do not have
                  any redundant 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.
 
OBSOLESCENCE OF   As part of our strategy, we have elected to support only
NETWORKING        selected providers of networking equipment and carrier
EQUIPMENT AND     services. For example, we support routers manufactured by
CARRIER           3Com, Bay/Nortel and Cisco, but not by other equipment
SERVICES WE       providers. Our services cannot be used by companies with
SUPPORT           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 would
                  seriously

LIMITED           Our success depends to a significant degree upon our
PROTECTION OF     software and other proprietary technology. The software
PROPRIETARY       industry has experienced widespread unauthorized
TECHNOLOGY        reproduction of software products. We have no patents. The
                  steps we have taken may not be adequate to deter competitors
                  from misappropriating our propriety 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. For more information, see "Business--Intellectual
                  Property Rights."
 
YEAR 2000         Many currently installed computer systems and software
ISSUES            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.
 
                  Our financial and accounting system for our accounts
                  payable, accounts receivable and general ledger accounts is
                  not Year 2000 compliant. We intend to upgrade this system
                  prior to March 31, 1999 in order to make the system Year
                  2000 compliant. We are still in the process of checking our
                  other systems. Our systems incorporate certain third-party
                  software and systems that may not be Year 2000 compliant. In
                  addition, our resellers', end users' and vendors' software
                  and systems 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 resellers or end users or otherwise
                  seriously damage our business.
 
                  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 approximately
                  $200,000 to upgrade our financial and accounting systems. If
                  we discover other Year 2000 errors or defects in our
                  internal systems, we could incur substantial costs in making
                  repairs. The resulting disruption of our operations could
                  seriously damage our business. For more information, see
                  "Management's Discussion and Analysis of Financial Condition
                  and Results of Operations--Liquidity and Capital Resources."
 
POTENTIAL         Because our products are designed to provide critical
LIABILITY         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 end-to-end network will be
                  available for at least 99.5% of the time in any given month.
                  In the event this guaranteed level of availability is not
                  achieved for an end user, we may be required to refund all
                  of our WAN management fees from the end user for that month.
                  We may, in some instances, refund amounts to customers for
                  circumstances beyond our control. For more information, see

NO PRIOR PUBLIC   Before this offering, there has been no public market for
MARKET            our common stock. NetSolve, the selling stockholders and the
                  underwriters of the offering will determine the initial
                  public offering price by negotiations, and this price may
                  not be the price at which the common stock will trade. See
                  "Underwriting" for a discussion of factors to be considered
                  in determining the initial public offering price. Although
                  the common stock will be quoted on the Nasdaq National
                  Market, an active trading market may not develop or be
                  sustained after this offering.
 
                  The market price of our common stock may fluctuate
                  substantially due to a variety of factors, including:
 
                     . quarterly fluctuations in our results of operations;
 
                     . 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;
 
                     . changes in accounting principles;
 
                     . sales of common stock by existing holders; and
 
                     . loss of key personnel.
 
                  In addition, the stock market is subject to other factors
                  outside our control that can cause extreme price and volume
                  fluctuations. Securities class action litigation has often
                  been brought against companies that experience volatility in
                  the market price of their securities. Litigation brought
                  against us could result in substantial costs and a diversion
                  of management's attention and resources, which could
                  seriously damage our business.
 
MANAGEMENT        After this offering, NetSolve's executive officers and
CONTROL OF        directors collectively will beneficially own approximately
NETSOLVE           % of the outstanding common stock. For more information,
                  see "Principal and Selling Stockholders." Thus, they will
                  continue to control NetSolve and, if they act together,
                  could elect all of the directors, appoint management and
                  control all matters submitted to our stockholders for a
                  vote.
 
FUTURE SALES OF   The market price of our common stock could drop as a result
SHARES            of sales of a large number of shares in the market after
                  this offering or in response to the perception that such
                  sales could occur. All of the      shares sold in this
                  offering will be freely tradable, while      of the other
                  shares outstanding after this offering will be "restricted
                  securities" under applicable securities laws. Most of these
                  restricted securities will be subject to 180-day lock-up
                  agreements with the underwriters. After this 180-day period
                  expires,      of such shares will be eligible for immediate
 
                                      14
<PAGE>
 
                  sale and     of such shares will become eligible for sale at
                  various times in the future upon expiration of applicable
                  holding periods under, and subject to the terms of, Rule
                  144. BancBoston Robertson Stephens can release shares from
                  one or more of the 180-day lock-up agreements without our
                  approval. In addition, holders of approximately     shares
                  (including shares issuable upon exercise of warrants) have
                  the right to request that we register those shares for sale
                  in the public market.
 
BROAD             We expect to use our net proceeds from this offering for
MANAGEMENT        general corporate purposes, giving our management broad
DISCRETION IN     discretion in the allocation of the net proceeds. Possible
USE OF PROCEEDS   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     Certain provisions of our certificate of incorporation and
PROVISIONS        Delaware law could be used by NetSolve's incumbent
                  management to make it more difficult for a third party to
                  acquire control of NetSolve, even if the change in control
                  might be beneficial to our stockholders. This could
                  discourage potential takeover attempts and could adversely
                  affect the market price of our common stock.
 
DILUTION;         Since our common stock has in the past been sold at prices
ABSENCE OF        substantially less than the initial public offering price
DIVIDENDS         that you will pay, you will suffer immediate dilution of $
                  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
 
  The net proceeds to NetSolve from the sale of the     shares of common stock
offered by NetSolve are estimated to be $    million ($    million if the
underwriters' over-allotment is exercised in full), assuming an initial public
offering price of $    per share and after deducting the estimated
underwriting discounts and commissions and estimated offering expenses payable
by the Company. The Company estimates that its expenses in connection with
this offering will total approximately $750,000. The Company 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 the Company's capitalization and financial flexibility;
 
  . increase the Company's visibility in the marketplace;
 
  . provide a public market for the Company's common stock;
 
  . facilitate the Company's future access to public equity markets; and
 
  . provide liquidity for the Company's existing stockholders.
 
  The Company believes that its enhanced financial position will provide the
Company with needed flexibility to respond to technological and market
developments as well as other future opportunities. The Company also believes
that its completion of this offering will improve its ability to attract and
retain customers and employees.
 
  The Company intends to use its net proceeds from this offering for general
corporate purposes, including working capital and possible acquisitions of,
and investments in, complementary businesses and technologies. Accordingly,
the Company will have broad discretion in the application of its net proceeds.
See "Risk Factors--Broad Management Discretion in Use of Proceeds." The
Company is not currently involved in negotiations with respect to, and has no
agreement or understanding regarding, any such acquisition or investment.
Pending these uses, the Company intends to invest its net proceeds in short-
term, investment-grade, interest-bearing securities.
 
                                DIVIDEND POLICY
 
  NetSolve has never declared or paid any cash dividends on its capital stock.
NetSolve intends to retain all available funds and any future earnings for use
in the operation of its business. Therefore, NetSolve does not anticipate
paying any cash or other dividends in the foreseeable future. Payment of
future dividends, if any, will be at the discretion of the Company's Board of
Directors after taking into account various factors, including the Company's
financial condition, results of operations, current and anticipated cash needs
and plans for expansion.

                                   DILUTION
 
  The pro forma net tangible book value of NetSolve as of September 30, 1998,
was $8,511,000, or $0.88 per share of common stock. 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 the Company's redeemable convertible preferred stock into common
stock. After giving effect to the sale of the     shares of common stock
offered by the Company in this offering at an assumed initial public offering
price of $   per share, and after deducting the estimated underwriting
discounts and commissions and estimated offering expenses payable by NetSolve,
the pro forma net tangible book value of NetSolve, as adjusted, at September
30, 1998, would have been approximately $    or $    per share of common
stock. This amount represents an immediate increase in pro forma net tangible
book value of $    per share to existing stockholders and an immediate
dilution in pro forma net tangible book value of $    per share to new
investors. The following table illustrates this per share dilution:

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  This Prospectus contains forward-looking statements which involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain
factors, including those set forth under "Risk Factors" and elsewhere in this
Prospectus. The following discussion should be read together with the
Consolidated Financial Statements and Notes included elsewhere in this
Prospectus.
 
OVERVIEW
 
  NetSolve provides remote 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 migrate efficiently to new technologies and
services. The Company was incorporated in September 1985 in the State of
Delaware and began operating in the second half of 1987. Until December 1996,
substantially all of the Company's services revenues were derived from the
sale of data transport services. These services consisted of provisioning and
providing Private Line and Frame Relay data networks. To provide these
transport services, the Company leased network transmission facilities from
major carriers, and it also resold AT&T's Frame Relay services. This business
was discontinued in the quarter ended December 31, 1996. See "--Discontinued
Operations" below. The Company began developing its first remote network
management service offering for WANs in early 1993 and began offering that
service, together with AT&T's Frame Relay services, in the quarter ended March
31, 1994. The Company began selling remote network management services
separately from its Frame Relay transport services in the quarter ended March
31, 1995. The Company introduced its first security service in the quarter
ended September 30, 1996, and began offering remote network management
services for LANs in the quarter ended June 30, 1997.
 
 Revenues
 
  The Company's revenues consist of network management services revenues as
well as equipment and other revenues. Network management services revenues
contain both recurring and non-recurring components, with 68% of network
management services revenues coming from recurring services in the first six
months of fiscal 1999.
 
  . Revenues from recurring services represent monthly fees charged to
    resellers or end users for the Company's remote 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.
 
  . 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 remote network
    management services. Non-recurring network management services
    revenues are generally recognized upon completion of the assignment
    or service which, in the case of project implementation services, is
    recognized on a per-location basis.
 
  NetSolve's network management services revenues are derived from contracts
with telecommunications carriers, value-added resellers of networking
equipment and services, and enterprises sold to by the Company's direct sales
force. Typical contracts for the Company's services include an initial
implementation fee plus a fixed monthly fee per managed device. The Company's
contracts with its 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 are
generally subject to cancellation fees ranging from twenty to eighty percent
of the recurring charges payable for the remainder of the service term. The
Company's contracts with resellers are typically from 12 to 36 months and, in
some cases, require the Company to continue providing services throughout the
term of the reseller's contract with the end user.
 
                                      21
<PAGE>
 
  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. 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 the control of the Company. As a result, the Company may,
in some instances, refund amounts to customers for circumstances beyond the
Company's control. The Company establishes a reserve against guarantees it
offers. Guarantee payments have not been significant in any month, other than
one event in which a major carrier's Frame Relay network was inoperable for an
extended number of hours. In order to enhance the Company's relationships with
its direct customers using that carrier's service, the Company refunded all of
the management fees for that month to those direct customers, even though the
outage was outside the coverage of NetSolve's guarantee. The cost of that
refund was $64,000. In the future, refunds made under the Company's guarantees
or otherwise could have a material adverse impact on the results of
operations. See "Risk Factors--System Failure" and "--Potential Liability."
 
  NetSolve's equipment and other revenues are derived from the resale of
customer premise equipment ("CPE") and from the sale of CPE maintenance
contracts to its network management services customers. Revenues from the sale
of CPE are recognized upon shipment to the end user. However, if the
transaction is financed through the Company's lease financing subsidiary, the
revenues are recognized upon sale of the underlying lease contract. Revenues
from CPE maintenance contracts are recognized on a monthly basis as the
services are provided. The Company expects to encourage end users to purchase
equipment from other sources, and therefore anticipates that revenues from CPE
sales will decline from quarter to quarter as the Company seeks to manage its
mix of revenues by limiting discounts on CPE.
 
  The Company currently has a network management services contract with two
business units within AT&T: AT&T Solutions and AT&T Business Network Services.
For fiscal 1996, 1997 and 1998, the Company derived 9%, 27% and 52% of its
total revenues, respectively, from AT&T. It is anticipated that AT&T will
continue to represent a high percentage of the Company's management services
revenues and that this concentration will increase during the latter half of
fiscal 1999 and at least a significant portion of fiscal 2000. No other
customer accounted for more than 10% of the Company's revenues in fiscal 1996,
1997 or 1998. See "Risk Factors--Dependence on AT&T" and "Business--
Relationship with AT&T."
 
  Historically, substantially all of the Company's revenues have been
generated from sales to customers in the United States although the Company
manages devices in several locations around the world for these customers.
 
 Costs and Expenses
 
  In March 1998, the Company relocated all of its operations from its 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, the Company upgraded its 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, 1998, the Company had net operating loss carryforwards of
approximately $18.2 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. The Company has alternative minimum
tax credit carryforwards of $177,000 which do not expire. 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 of 1986. The annual limitation may result in the
expiration of the net operating losses before utilization.

 Discontinued Operations
 
  In December 1996, the Company decided to discontinue its data transport
services business segment and it sold its Private Line portion of that segment
to Intermedia Communications Inc. of Florida ("Intermedia"). The sale to
Intermedia was closed on December 30, 1996 at a price of $12.3 million. As a
part of this transaction, all customer and supplier contracts related to the
Private Line 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. To ease the transition associated with this sale, the Company
agreed to provide management services to the transferred customer base through
October 1997. The Company recorded revenues of $500,000 and $715,000 in fiscal
years 1997 and 1998, respectively, with respect to these services. To complete
the discontinuance of this business segment, on October 1, 1997, the Company
assigned its rights and obligations to customer and supplier contracts for
Frame Relay transport services to NetPlus, Inc. The purchase price was
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.

SIX MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO SIX MONTHS ENDED SEPTEMBER 30,
1997
 
 Revenues
 
  Total Revenues. Total revenues increased 79%, from $6.7 million in the first
six months of fiscal 1998 to $12.0 million in the first six months of fiscal
1999.
 
  Network Management Services. Revenues from network management services
increased 74%, from $3.2 million in the first six months of fiscal 1998 to
$5.6 million in the first six months of fiscal 1999, representing 49% and 47%
of total revenues, respectively. The dollar increase 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. Increased implementation
fees in the first six months of fiscal 1999 were largely due to a change in
Company policy in the quarter ended March 31, 1998 which resulted in the
Company 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. See "--Overview--
Discontinued Operations."
 
  Equipment and Other. Revenues from equipment sales and other increased 85%,
from $3.4 million in the first six months of fiscal 1998 to $6.3 million in
the first six months of fiscal 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. The Company expects to encourage end
users to purchase equipment from other sources, and therefore anticipates that
revenues from CPE sales will decline from quarter to quarter as the Company
seeks to manage its mix of revenues by limiting discounts on CPE.
 
 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 38%, from $2.8 million in the first six months of fiscal 1998 to
$3.9 million in the first six months of fiscal 1999, representing 86% and 69%
of network management services revenues in the first six months of fiscal 1998
and in the first six months of fiscal 1999, respectively. 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 facilities as described under "--
Overview--Costs and Expenses" above 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 the
Company for replacement of failed units. This cost is expensed as incurred.
Cost of equipment and other increased 92%, from $2.6 million in the first six
months of fiscal 1998 to $5.0 million in the first six months of fiscal 1999,
representing 75% and 78% of equipment and other revenues in the first six
months of fiscal 1998 and in the first six months of fiscal 1999,
respectively. The increase in dollars and as a percent of equipment and other
revenues was due to higher volume of CPE sales in the first six months of
fiscal 1999 to the Company's 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 internal software
systems, selecting and integrating purchased software applications, developing
software tools for the Company's network management services, developing the
Company's Web-enabled software applications
 
                                      24
<PAGE>
 
that give customers access to network management information, and defining and
developing operating processes for new services. Development expenses
decreased 14%, from $958,000 in the first six months of fiscal 1998 to
$824,000 in the first six months of fiscal 1999, representing 14% and 7% of
total revenues in the first six months of fiscal 1998 and the first six months
of fiscal 1999, respectively. The decrease in dollars and as a percentage of
total revenues was due to the development of the Company's LAN product which
was introduced in the first quarter of fiscal 1998 and reduced usage of third
party contract programming resources. This decrease was partially offset by
increased depreciation on development tools. The decrease was also affected by
the Company's decision to manage development spending to a lower level as a
percentage of total revenues in the first six months of fiscal 1999, after
having accelerated spending in the first six months of fiscal 1998 in order to
support future revenue growth, cost reduction and service quality.
 
  Sales and Marketing. Sales and marketing expenses consist primarily of
salaries, commissions, travel and costs associated with creating awareness for
the Company's services. Sales and marketing expenses increased 4%, to $1.4
million, representing 21% and 12% of total revenues in the first six months of
fiscal 1998 and the first six months of fiscal 1999, respectively. In the
first six months of fiscal 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 when the Company closed its remaining remote sales offices and
relocated all sales activities to the Company's headquarters in Austin. 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 the Company began to rely
more on an indirect distribution strategy. The Company anticipates sales and
marketing costs may increase slightly as a percentage of total revenues over
the next 12 months, as additional sales and marketing personnel are added.
 
  General and Administrative. General and administrative expenses consist
primarily of expenses related to the Company's human resources, finance and
executive departments. Included in human resources spending is all Company-
sponsored training as well as most costs of recruiting and relocating new
employees. General and administrative expenses increased 12%, from $937,000 in
the first six months of fiscal 1998 to $1.1 million in the first six months of
fiscal 1999, representing 14% and 9% of total revenues in the first six months
of fiscal 1998 and the first six months of fiscal 1999, respectively. The
dollar increase was due primarily to the addition of human resources
professionals who were responsible for enhancing training and recruiting
programs in preparation for growth. The increase was also due to higher
facility costs, and additional spending for outside training programs. The
decrease as a percentage of revenues is primarily the result of higher total
revenues in fiscal 1998.
 
 Other Income (Expense), Net
 
  Other income (expense), net consists primarily of interest expense from the
Company's leases for capital equipment, offset by interest income earned on
the Company's cash balances. Net other income decreased 5%, from $75,000 in
the first six months of fiscal 1998 to $71,000 in the first six months of
fiscal 1999, both representing 1% of total revenues in the first six months of
fiscal 1998 and the first six months of fiscal 1999, respectively. The dollar
decrease in the first six months of fiscal 1999 was due to higher interest
income in the first six months of fiscal 1998 earned from a higher level of
funds available for investment offset by a write-off of contract development
expenses in the first six months of fiscal 1998 and increased interest paid on
capital lease obligations in the first six months of fiscal 1999.

YEAR ENDED MARCH 31, 1998 COMPARED TO YEAR ENDED MARCH 31, 1997
 
 Revenues
 
  Total Revenues. Total revenues increased 130%, from $6.3 million in fiscal
1997 to $14.5 million in fiscal 1998.
 
  Network Management Services. Revenues from network management services
increased 159%, from $2.8 million in fiscal 1997 to $7.3 million in fiscal
1998, representing 45% of total revenues in fiscal 1997 and 50% of total
revenues in fiscal 1998. The dollar and percentage increase 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. Increased implementation fees in fiscal 1998 were largely due to
a change in Company policy in the quarter ended March 31, 1998 which resulted
in the Company 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. See "--Overview--
Discontinued Operations."
 
  Equipment and Other. Revenues from equipment and other increased 107%, from
$3.5 million in fiscal 1997 to $7.2 million in fiscal 1998, primarily as a
result of increased sales of CPE.
 
 Cost of Revenues
 
  Cost of Network Management Services. Cost of network management services
increased 134%, from $2.4 million in fiscal 1997 to $5.7 million in fiscal
1998, representing 86% and 78% of network management services revenues in
fiscal 1997 and fiscal 1998, respectively. 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 103%,
from $2.6 million in fiscal 1997 to $5.3 million in fiscal 1998, representing
76% and 74% of equipment and other revenues in fiscal 1997 and fiscal 1998,
respectively. The dollar increase was due primarily to the higher volume of
CPE sales in fiscal 1998 and, to a lesser extent, increased equipment
maintenance revenues.
 
 Operating Expenses
 
  Development. Development expenses increased 51%, from $1.3 million in fiscal
1997 to $1.9 million in fiscal 1998, representing 20% and 13% of total
revenues in fiscal 1997 and fiscal 1998, respectively. The dollar increase is
due to higher development spending in fiscal 1998 enabled by the sale of the
Company's transport business in the third quarter of fiscal 1997. This sale
provided a source of working capital to invest in the Company's 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 is
primarily the result of higher total revenues in fiscal 1998.
 
  Sales and Marketing. Sales and marketing expenses increased 14%, from $2.2
million to $2.6 million, representing 36% and 18% of total revenues in fiscal
1997 and fiscal 1998, respectively. This dollar increase was due to increased
facility costs related to the closing of most of the Company's remote sales
offices as the Company began consolidating sales efforts at its Austin
headquarters as well as increased public relations and market awareness
efforts. The decrease as a percentage of total revenues reflects 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 the
Company began to rely more on an indirect distribution strategy.
 
                                      26
<PAGE>
 
  General and Administrative. General and administrative expenses increased
45%, from $1.5 million in fiscal 1997 to $2.2 million in fiscal 1998,
representing 24% and 15% of total revenues in fiscal 1997 and fiscal 1998,
respectively. The dollar increase was due primarily to the addition of human
resources professionals beginning in the first quarter of fiscal 1998 who were
responsible for enhancing training and recruiting programs in preparation for
growth. The dollar increase was also due 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 1998.
 
 Other Income (Expense), Net
 
  Net other income increased 268%, from $34,000 in fiscal 1997 to $125,000 in
fiscal 1998, representing 1% of total revenues in both fiscal 1997 and fiscal
1998. The dollar increase in fiscal 1998 was due to higher interest income in
fiscal 1998 earned from a higher level of funds available for investment
offset by a write-off of contract development expenses and obsolete equipment
and increased interest on capital lease obligations in fiscal 1998.
 
YEAR ENDED MARCH 31, 1997 COMPARED TO YEAR ENDED MARCH 31, 1996
 
 Revenues
 
  Total Revenues. Total revenues increased 72%, from $3.7 million in fiscal
1996 to $6.3 million in fiscal 1997.
 
  Network Management Services. Revenues from network management services
increased 262%, from $782,000 in fiscal 1996 to $2.8 million in fiscal 1997,
representing 21% of total revenues in fiscal 1996 and 45% of total revenues in
fiscal 1997. Substantially all of the dollar increase was due to growth in the
number of managed devices under contract and, to a lesser extent, a contract
to manage the customer base of the discontinued transport operations for
Intermedia.
 
  Equipment and Other. Revenues from equipment and other increased 21%, from
$2.9 million in fiscal 1996 to $3.5 million in fiscal 1997, primarily as a
result of increased sales of CPE.
 
 Cost of Revenues
 
  Cost of Network Management Services. Cost of network management services
increased 344%, from $548,000 in fiscal 1996 to $2.4 million in fiscal 1997,
representing 70% and 86% of network management services revenues in fiscal
1996 and fiscal 1997, respectively. The dollar increase was due primarily to
the addition of personnel to accommodate growth, upgrades to the network
management infrastructure, facilities expansion to accommodate new operations
personnel, and increased recruiting and relocation costs associated with
adding personnel. The percentage increase was due to the reassignment of
technical personnel following the sale of the discontinued transport
operations in December 1996.
 
  Cost of Equipment and Other. Cost of equipment and other increased 32%, from
$2.0 million in fiscal 1996 to $2.6 million in fiscal 1997, representing 69%
and 76% of equipment and other in fiscal 1996 and fiscal 1997, respectively.
The dollar increase was due to the higher volumes of CPE sales in fiscal 1997,
lower gross margins on CPE due to higher discounting in fiscal 1997, and lower
equipment maintenance gross margins resulting from certain contracts yielding
higher gross margins sold to Intermedia.
 
Operating Expenses
 
  Development. Development expenses increased 11%, from $1.1 million in fiscal
1996 to $1.3 million in fiscal 1997, representing 31% and 20% of total
revenues in fiscal 1996 and fiscal 1997, respectively. The dollar increase
resulted primarily from hiring additional development personnel. The decrease
as a percentage of total revenues reflected the significantly higher revenues
in fiscal 1997.
 
                                      27
<PAGE>
 
  Sales and Marketing. Sales and marketing expenses increased 207%, from
$732,000 to $2.2 million, representing 20% and 36% of total revenues in fiscal
1996 and fiscal 1997, respectively. This dollar increase was due primarily to
the reassignment of sales personnel, who were previously focused on the
Company's discontinued transport business, to the selling of network
management services. To a lesser extent, the dollar increase resulted from
increased public relations expenditures in fiscal 1997. The increase as a
percentage of total revenues reflected higher levels of spending to support
more rapid growth of the network management services business following the
sale of the discontinued transport operations.
 
  General and Administrative. General and administrative expenses increased
10%, from $1.4 million in fiscal 1996 to $1.5 million in fiscal 1997,
representing 37% and 24% of total revenues in fiscal 1996 and fiscal 1997,
respectively. The dollar increase was due primarily to increased personnel and
recruiting expenses partially offset by reduced facilities costs. The decrease
as a percentage of total revenues is primarily the result of higher total
revenues in fiscal 1997.
 
 Other Income (Expense), Net
 
  Other income (expense), net increased from a net expense of $110,000 in
fiscal 1996 to net income of $34,000 in fiscal 1997, representing (3%) and 1%
of total revenues in fiscal 1996 and fiscal 1997, respectively. The dollar
increase in fiscal 1997 was due primarily to higher interest income in fiscal
1997 as the result of a higher level of funds available for investment
following the sale of the discontinued transport operations. The dollar
increase was offset partially by lower average outstanding obligations under
capital leases in fiscal 1997.
 
QUARTERLY RESULTS OF OPERATIONS
 
  Although the Company's total revenues have increased in each of the last
eight quarters, results of operations have varied from quarter to quarter.
Accordingly, the Company believes that period to period comparisons of results
of operations are not necessarily meaningful and should not be relied upon as
indications of future performance. The Company's operating results may
fluctuate as a result of many factors, including the ability of the Company 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, the Company 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 the Company's business. Finally, there can be no assurance
that the Company will be profitable in the future or, if the Company is
profitable, that its levels of profitability will not vary significantly
between quarters. See "Risk Factors--Fluctuations in Quarterly Performance."

  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 ten quarters in the period ended September 30, 1998. This quarterly
information is unaudited and has been prepared on the same basis as the
Company's audited annual consolidated financial statements and, in the opinion
of the Company's management, includes all adjustments (consisting only of
normal recurring adjustments) necessary for a fair presentation of the
information for the periods presented, when read together with the Company's
Consolidated Financial Statements and Notes appearing elsewhere in this
Prospectus. Operating results for any quarter are not necessarily indicative
of results for any future period.

</TABLE>
 
  The trends discussed in the annual comparisons of operating results from
fiscal 1997 to fiscal 1998 and the first six months of fiscal 1998 to the
first six months of fiscal 1999 are generally applicable to the comparison of
quarters within the ten quarterly periods ended September 30, 1998. 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 whereby the Company managed
 
                                      30
<PAGE>
 
the customer base of the discontinued transport business. The larger than
usual sequential growth in equipment and other revenues in the quarter 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 network management services as a percent of network
management services revenues in the quarters ended March 31, 1997 and June 30,
1997 was due to planned increases in spending in order to prepare for growth
following the sale of the discontinued transport operations in December 1996,
and to evaluate alternate ways to increase the number of managed devices per
employee in future periods.
 
  The increase in cost of equipment and other as a percent of equipment and
other revenues in the quarter ended December 31, 1996 resulted from a
significant increase in CPE sales, which have lower gross margins than
equipment maintenance services. This percentage increase also reflected the
sale of customer maintenance contracts, which typically yielded higher average
gross margins, in connection with the sale of the discontinued transport
operations. The increase in this cost 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. The Company expects to encourage end users to purchase equipment
from other sources, and therefore anticipates that revenues from CPE sales
will decline from quarter to quarter as the Company seeks to manage its mix of
revenues by limiting discounts on CPE.
 
  The increase in development expenses in the quarter ended June 30, 1997 was
due to planned increases in personnel and contract programming following the
sale of the discontinued transport operations.
 
  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 its inception the Company has funded its operations primarily through:
 
  . private sales of capital stock totaling $28.3 million, including most
    recently the sale of capital stock in fiscal 1993 for $9.8 million;
 
  . the sale of its discontinued transport business for $12.3 million in
    December 1996;
 
  . leases on capital equipment;
 
  . working capital lines of credit; and
 
  . cash provided by operations in fiscal 1995 and 1996 of $1.1 million
    and $1.0 million, respectively.
 
  The Company used cash in fiscal 1997 and fiscal 1998 of $1.5 million and
$2.2 million, respectively, and $1.1 million in the first six months of fiscal
1999, to purchase capital assets primarily used in the delivery of its network
management services. The Company anticipates spending between $900,000 and
$1.4 million for capital expenditures during the last six months of fiscal
1999, although it currently has no material commitments for capital
expenditures. Proceeds from leases of capital equipment totaled $218,000 and
$1.7 million in fiscal 1997 and 1998, respectively, and $562,000 in the first
six months of fiscal 1999. The Company paid $514,000 and $257,000 toward its
lease obligations for capital equipment in fiscal 1997 and fiscal 1998,
respectively, and $328,000 in the first six months of fiscal 1999.
 
  The Company's financial and accounting system for accounts payable, accounts
receivable and general ledger accounts is not Year 2000 compliant. The Company
intends to upgrade this system prior to March 31, 1999, in order to make the
system Year 2000 compliant. The Company is still in the process of checking
its other systems, although the Company believes they are currently Year 2000
compliant. However, these systems incorporate certain third-party software and
systems that may not be Year 2000 compliant. In addition, resellers', end
users' and vendors' software and systems may not be Year 2000 compliant. The
failure of systems maintained by the Company's resellers, end users and
vendors to be Year 2000 compliant could cause the Company to incur significant
expenses to remedy any problems, reduce the Company's revenues from such end
users, or otherwise have a material adverse effect on the Company's business,
financial condition and results of operations.
 
                                      31
<PAGE>
 
  The Company has not incurred significant costs to date complying with Year
2000 requirements, and does not believe that it will incur significant costs
for such purposes in the foreseeable future. The Company expects to spend
approximately $200,000 to upgrade its financial and accounting systems. Any
disruption of the Company's operations or additional unanticipated expenses
could have an adverse effect on the Company's business, financial condition
and results of operations. See "Risk Factors--Year 2000 Issues."
 
  In December 1996, the Company terminated its $1.0 million bank line of
credit prior to the closing of the sale of the transport business. If
desirable, the Company believes it can obtain a similar working capital line
of credit on acceptable terms.
 
  As of September 30, 1998, the Company had $117,000 in cash and cash
equivalents and $2.9 million in net accounts receivable. The Company believes
that the net proceeds from this offering, together with cash generated from
operations, will be sufficient to fund its anticipated working capital needs,
capital expenditures and any potential future acquisitions for at least twelve
months. In the event the Company's plans or assumptions change or prove to be
inaccurate, or if the Company consummates any unplanned acquisitions of
businesses or assets, the Company 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.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
  In June 1997, the Financial Accounting Standards Board issued SFAS 130,
Reporting Comprehensive Income. This statement requires the Company to report
components of comprehensive income in a financial statement that is displayed
with the same prominence as other financial statements. The Company adopted
SFAS 130 in the six months ended September 30, 1998. 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 any period presented.
 
  In June 1997, the Financial Accounting Standard Board issued SFAS 131,
Disclosures about Segments of an Enterprise and Related Information. This
statement requires that a public business enterprise report financial and
descriptive information about its reportable operating segments. SFAS 131 is
effective for fiscal years beginning after December 15, 1997, but is not
required for interim disclosure in the first year of adoption. The Company
expects that implementation of this standard will not have a material effect
on its financial disclosures.

                                   BUSINESS
 
  NetSolve offers a range of remote 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. The
Company's 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. NetSolve furnishes its network
management services remotely 24 hours per day, seven days per week from its
Network Management Center in Austin, Texas, and it offers software tools that
allow companies to access up-to-date network status reports through standard
Web browsers. The Company also offers around-the-clock remote security
protection services for networks' Internet and intranet perimeter points. The
Company's security offerings currently include a managed firewall service and
a remote intrusion detection and response service. The Company has offered
network management services since 1995 and currently has over 375 end users
representing more than 4,800 managed sites. The Company targets 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, and
provides services both directly to end users as well as 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 ("WANs") and local area networks ("LANs"). This has
resulted in a dramatic increase in network traffic as well as heightened
requirements for network performance. It has also driven growth in the amount
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 such as Frame Relay, Asynchromous
Transfer Mode ("ATM") and Internet Protocol ("IP"). While traditional
architectures provide dedicated circuits between computing facilities and
fixed bandwidth regardless of traffic flow, new switched data technologies
share and dynamically allocate bandwidth based on prevailing traffic patterns.
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.
 
                                      33
<PAGE>
 
Further, the tools available to manage today's networks are themselves 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 ("IT") professionals. An independent
industry analyst estimates that between 15% and 30% of permanent IT positions
were unfilled in mid-1998 and that the total volume of IT work will increase
45% by 2003. 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.
 
NETSOLVE'S SOLUTION
 
  NetSolve offers remote 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. The Company also offers security protection for
network perimeter points such as an enterprise's Internet or intranet
connections. The Company's 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.
The Company currently has over 375 middle market end users that maintain more
than 4,800 managed sites. The Company believes its solution offers the
following key benefits:
 
  Full Breadth of Network Management Services. The Company's 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 NetSolve,
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. NetSolve is 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, NetSolve often is able to offer a better
network solution at a lower cost than if an end user attempted to manage its
network in-house. Furthermore, the Company evaluates, purchases, develops and
integrates application-specific software and tools that allow the Company to
deliver reliable solutions at low costs. The Company
 
                                      34
<PAGE>
 
supports only the relatively small 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,
the Company is able to leverage economies of scale in managing multiple end-
user networks.
 
  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. NetSolve provides its remote network management and security
services to end-user locations worldwide 24 hours per day, seven days per
week. The Company's 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. NetSolve's network
management professionals act as an extension of the customer's IT staff. By
relying on NetSolve's 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. NetSolve reports
to end users on an ongoing basis and recommends upgrades or changes when
appropriate.
 
  Web-Enabled Network Monitoring and Reporting. End users can out-task to
NetSolve 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 the
Company's 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. NetSolve also provides end users with reports of network
activity periodically or on demand.
 
STRATEGY
 
  NetSolve's goal is to be a leading provider of remote network management
services. The key elements of the Company's strategy include the following:
 
  Target Middle Market Enterprises. The Company believes a significant market
opportunity exists for its 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. The Company believes its remote network management
and security services offer an attractive solution for many middle market
companies and intends to target these companies in marketing its existing
services and developing new services.
 
  Support Leading Technologies. The Company has been able to provide cost-
effective solutions to its customers by supporting only the leading providers
of networking hardware and carrier services. The suppliers which the Company
supports include AT&T, MCI/WorldCom and Sprint in the data transport arena,
and 3Com, Bay/Nortel, Cabletron and Cisco in the market for customer premise
equipment ("CPE"). By designing its services to support this select group of
leading service and equipment vendors, the Company seeks to leverage its
expertise, technologies and processes, while still providing support for the
needs of most middle market companies. The Company intends to continue to
develop its processes and tools to support new hardware and services
introduced by leading vendors. This ongoing support may require NetSolve to
modify existing services and, in some cases, develop new services. For
example, the Company recently has begun managing ATM devices and is actively
attempting to define new value added services.
 
  Expand Service Offerings. The Company seeks to expand its service offerings
by leveraging its existing expertise, technologies and processes. In August
1996, the Company introduced a security service that provides
 
                                      35
<PAGE>
 
remote intrusion detection. This offering utilized the Company's Network
Management Center and tools infrastructure and was supplemented by additional
proprietary and third-party tools, as well as engineers with specific network
security expertise. In the future, the Company intends to develop proactive
network management services involving performance engineering and capacity
planning.
 
  Add Distribution Partners. The Company believes it can market its services
to middle market companies most effectively by partnering with resellers that
bundle the Company's services with transport services or CPE. The Company
believes it can expand its current distribution relationships to include other
major carriers, competitive local exchange carriers ("CLECs") and Internet
service providers ("ISPs"), and that it can also establish sales referral
relationships with various manufacturers of networking hardware. The Company
believes that these relationships will provide the Company with a significant
competitive advantage.

  The Company has two branded remote network management service packages:
ProWatch for WANs and ProWatch for LANs.
 
    ProWatch for WANs. NetSolve introduced its 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
  NetSolve and certain of its 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 ("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) monitoring; and (3)
  performance reporting. The ProWatch for WANs service generally includes
  a guarantee to provide 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. See "Management's Discussion and
  Analysis of Financial Condition and Results of Operations--Overview."
  Substantially all of the Company's recurring network management
  services revenues are derived from ProWatch for WANs and related WAN
  services. See "Risk Factors--Dependence on WAN Services; Need to
  Develop and Sell Additional Services."
 
    ProWatch for LANs. NetSolve introduced its LAN remote management
  service in May 1997 to measure, monitor and manage the routers,
  switches and intelligent hubs in corporate LANs. This service can also
  monitor the availability of servers manageable by the Simple Network
  Management
 
                                      37
<PAGE>
 
  Protocol ("SNMP"). NetSolve LAN management services are marketed by
  NetSolve and certain of its 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, the Company
  leveraged the expertise, technologies and processes it 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
 
  The Company's 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 ("VPN") configuration management. The
pricing for these security services is generally established as a monthly fee
on a per-managed-device basis. Key services offered by the Company include:
 
    Managed Firewall Service. This service provides active management of
  the firewall by NetSolve security engineers reviewing firewall logs and
  alarms daily to detect suspicious activity and consulting with the end
  user regarding potential changes in the firewall configuration.
  NetSolve manages the firewall configuration and VPN connections on an
  ongoing basis. The end user receives security reports and a
  consultation session with a security engineer on a monthly basis.
  ProWatch Secure Managed Firewall Service is supported on Cisco's PIX
  Firewall series. The Cisco PIX Firewall is configured by a NetSolve
  security engineer 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 the
  Company's Remote Intrusion Detection and Response Service.
 
    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.
  The Company introduced its ProWatch Secure Remote Intrusion Detection
  and Response Service in August 1996.
 
  End users may purchase these services individually, together or as a
combined network management service offering. In addition, the Company is
seeking to offer these security services through marketing partnerships. For
example, in October 1998, the Company, Cisco and CIGNA announced jointly that
CIGNA would offer insurance coverage to companies who agree to use ProWatch
Secure Remote Intrusion Detection and Response Service and Cisco's data
security technology and equipment.
 
 Web-Enabled Tools
 
  The Company's 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 NetSolve. End users access these tools through a standard
Web browser using the Company's 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
 
  The Company resells CPE from leading network equipment manufacturers or
their resellers. This equipment typically includes routers, CSUs and LAN
switches and is obtained primarily from Cisco and, to a lesser extent, from
3Com, Bay/Nortel and Paradyne.
 
  The Company also resells 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
 
  The Company's 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. The
Company currently has over 375 middle market end users that maintain more than
4,800 managed sites. The Company's end users consist of its direct customers
as well as customers of its resellers. The following is a list of selected
NetSolve direct customers grouped by industry.

  When sold to end users by resellers, the Company's services are typically
sold under the reseller's trade or brand name. In some instances, however, the
reseller utilizes NetSolve's brand names. Certain of the Company's services
sold to resellers are provided directly to the reseller either to support the
reseller's network (as in the case of certain carriers) or are embedded as a
portion of a carrier transport service sold to end users. The Company's
resellers include AT&T, Enterprise Network Services, eSpire and Intermedia.
 
  The Company has derived a significant portion of its revenue from one
reseller, AT&T. See "Business--Relationship with AT&T." No other NetSolve
customer accounted for more than 10% of the Company's revenues in any of the
last three fiscal years.
 
RELATIONSHIP WITH AT&T
 
  The Company has 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 NetSolve's network management services to AT&T
customers in conjunction with AT&T's overall network solution offering.
NetSolve's technicians work directly with AT&T's sales and marketing personnel
and the end users to design, implement and manage the end users' networks. For
fiscal 1996, 1997, and 1998, the Company derived 9%, 27% and 52% of its total
revenues, respectively, from AT&T. It is anticipated that this concentration
of revenue from AT&T will continue, and it is expected to increase during the
last half of fiscal 1999 and a significant portion of fiscal 2000.
 
                                      39
<PAGE>
 
  NetSolve provides its 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 the later of December 31, 1999 or
six months following notice of termination. Following the termination date,
NetSolve is required to continue to provide services to then-existing end
users. The volume of such business that may be moved by AT&T to other entities
may not exceed 8% per month times the dollar amount billed in the last full
month prior to termination.
 
  The arrangements with AT&T Business Network Services are in support of two
carrier services: COFRAD (Central Office Frame Relay Assembler and
Disassembler) and Frame Relay Plus. The arrangements in support of COFRAD will
terminate December 31, 1998. The arrangements in support of Frame Relay Plus
are currently in place for a trial period which ends upon the installation of
1,000 managed devices. As of September 30, 1998, approximately 400 managed
devices had been installed under this arrangement. Either AT&T or the Company
may terminate these arrangements upon ninety days' notice. The Company
believes the arrangement in support of Frame Relay Plus will be renewed upon
completion of the trial period.
 
SALES AND MARKETING
 
  NetSolve markets its 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 1998, 29% of network management service revenues were derived from
direct customers. The Company's strategy is to build its reseller channels and
the Company expects that these channels will represent an increasing
percentage of the Company's network management revenues for the foreseeable
future. The Company's resellers include AT&T, Enterprise Network Services,
eSpire and Intermedia. All sales of the Company's services to date have been
made in the U.S. However, the Company remotely manages locations around the
world for these customers.
 
  At September 30, 1998, the Company employed ten 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 the Company's services. Reseller support by the NetSolve sales
organization includes assistance with responses to requests for proposals,
network design and proposal generation, and participation in sales calls to
potential customers. The NetSolve sales organization also helps resellers
define services and familiarize the reseller's sales forces with the Company's
services and networking options. All of the Company's sales and marketing
employees are based at the Company's headquarters in Austin.
 
  At September 30, 1998, the Company 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 the Company's Web site. Public relations activities
include obtaining media coverage and public recognition. 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 its larger reseller partners to
define, develop and implement embedded carrier services.
 
SOFTWARE DEVELOPMENT
 
  The role of the Company's software development group, which consisted of 11
people at September 30, 1998, is to develop or integrate the tools utilized by
the Company to manage networks and to develop software applications, such as
ProWatch Exchange, which become components of the Company's services. While
certain of the Company's applications and tools are proprietary, all are built
using industry-standard protocols, tools and development environments,
including HyperText Markup Language (HTML), Java, Java Script, Microsoft
Access, Oracle 8.x relational database software and development tools, Remote
Monitoring (RMON), SNMP and Visual Basic.

OPERATIONS
 
  The NetSolve operations organization, comprised of 78 individuals at
September 30, 1998, is responsible for delivery of the Company's services to
end users. By defining network management tasks into sets of tightly defined
services, the Company is able to deliver functionality to its end users at
cost-effective prices. The Company's 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 the
Company's operations group. The first level of service delivery is the
Company's 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. From the Network Management Center, responses to polls to
managed devices are monitored continuously and trouble tickets are opened 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, the Company can utilize network engineers with a broad range of
skills and experience.
 
  The Company's 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, the Company employs a SONET
ring which is served from two separate local exchange carrier serving offices.
The Company's facility contains two separate rooms with redundant computing
and networking equipment, each of which is monitored 24 hours per day, seven
days per week. See "Risk Factors--System Failure."
 
  The Company delivers its services utilizing a workforce with a wide range of
skills, from entry-level to highly trained networking professionals. The
Company uses a strict operational methodology combined with proprietary
software tools to leverage its workforce. The Company believes it can meet its
requirements for networking professionals by hiring experienced networking
professionals and by recruiting and training recent college graduates. See
"Risk Factors--Limited Supply of Qualified IT Professionals."
 
COMPETITION
 
  The competition which the Company faces comes from a number of different
sources. Currently, the Company competes primarily with the internal IT
organizations of actual or potential end users of the Company's 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 like the Company. The Company believes 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.
 
  The remote network management service market is new, highly fragmented,
rapidly evolving and largely undefined. There are few substantial barriers to
entry, and the Company expects that it 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 the Company. The Company believes 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
 
                                      41
<PAGE>
 
conformity with industry standards. While the Company believes that it
competes favorably with respect to these factors, there can be no assurance
that the Company will have the resources or expertise to compete successfully
in the future.
 
  The Company currently faces 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 its security services, the Company currently faces
competition from computer systems vendors, such as IBM. The Company also faces
potential competition from IT consulting firms, systems integrators, VARs, and
local and regional network services firms and other new entrants into its
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 does the Company.
There can be no assurance that the Company will be able to compete
successfully against current or potential competitors. The failure of the
Company to compete successfully would have a material adverse effect on the
Company's business, operating results and financial condition.
 
  The Company also faces potential competition from resellers with which the
Company currently partners, or could partner, to market and sell the Company's
services. These resellers generally have substantially greater resources than
the Company and could directly compete, rather than partner, with the Company.
Such a decision by the Company's resellers would have a material adverse
effect on the Company's business, operating results and financial condition.
 
  With respect to the sale of equipment and on-site equipment maintenance
services, the Company competes primarily with the equipment manufacturers and
their resellers.
 
  See "Risk Factors--Competition."
 
INTELLECTUAL PROPERTY RIGHTS
 
  The Company relies 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 its services. The Company
has recently applied for a patent with the United States Patent Office. This
patent relates to software technology which allows the Company to poll, or
communicate with, large numbers of routers or other SNMP devices over multiple
WANs. Although the Company currently has no patented technology that would
preclude or inhibit competitors from entering the Company's market, the
Company intends to continue to evaluate the appropriateness of such protection
and to seek patent protection for its inventions when appropriate. There can
be no assurance that patents will issue from the 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 the Company. The Company has registered the name NetSolve and its
distinctive logo as separate service marks in the U.S. and various state
trademark offices. The Company also has service mark registrations pending for
ProWatch, ProWatch for WANs, ProWatch for LANs, ProWatch Exchange and ProWatch
Secure. There can be no assurance that such trademarks will be granted. The
Company has not made any foreign patent or trademark filings. The Company has
entered into proprietary rights and confidentiality agreements with its
employees, and generally enters into nondisclosure agreements with its
suppliers, distributors and appropriate customers in order to limit access to
and disclosure of its proprietary information.
 
  There can be no assurance that these contractual arrangements or the other
steps taken by the Company to protect its intellectual property will prove
sufficient to prevent infringement or misappropriation of the Company's
technology or to deter independent third-party development of similar
technologies. Any such infringement or misappropriation, should it occur,
could have a material adverse effect on the Company's business, results of
operations and financial condition. Furthermore, litigation may be necessary
to enforce the Company's intellectual property rights, to protect the
Company's trade secrets, to determine the validity and scope of the
proprietary rights of others, or to defend against claims of infringement or
invalidity. Such litigation
 
                                      42
<PAGE>
 
could result in substantial costs and diversion of resources and could have a
material adverse effect on the Company's business, results of operations and
financial condition. See "Risk Factors--Limited Protection of Proprietary
Technology."
 
  In June 1996, in connection with the Company's registration of the service
mark NetSolve, GRC International, Inc. ("GRC") initiated a proceeding pursuant
to which GRC alleged that the Company's use of the name NetSolve infringed
certain common law intellectual property rights of GRC. This proceeding
resulted in the negotiation and execution of an agreement, dated September 9,
1997, between the Company and GRC pursuant to which, among other things, GRC
withdrew its opposition and consented to NetSolve's service mark registration.
GRC retains the right to use the name NetSolve to describe a particular
software product, and NetSolve retains the full right to its corporate name.
The Company also agreed with GRC to refrain from using NetSolve as a brand
name to describe products and services. The Company believes that the limited
joint use of the name NetSolve by GRC will not have a material adverse effect
on the Company. The Company's service mark for the name NetSolve was
registered and issued on March 10, 1998. With the exception of GRC, the
Company has not, to date, been notified that its services infringe the
proprietary rights of third parties; however, there can be no assurance that
third parties will not claim infringement or indemnification by the Company
with respect to current or future services or products. The Company expects
that participants in its markets will be increasingly subject to infringement
claims as the number of services and competitors in the Company's 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 the Company from using important
technologies or methods, subject the Company to substantial damages, or
require the Company to enter into royalty or licensing agreements. Such
royalty or licensing agreements might not be available on terms acceptable to
the Company or at all. As a result, any such claim could have a material
adverse effect upon the Company's business, results of operations and
financial condition.
 
EMPLOYEES
 
  As of September 30, 1998, NetSolve had 116 full-time employees, including 15
in sales and marketing, 11 in development, 78 in operations and 12 in finance
and administration. NetSolve's success depends to a significant degree upon
the continued contribution of its executive management and network management
and engineering teams. See "Risk Factors--Dependence on Services of Current
Chief Executive Officer." The Company intends to hire additional software
development personnel to broaden its development capabilities. The future
success of the Company will depend in large part upon its continued ability to
attract and retain highly skilled and qualified personnel. Competition for
such personnel is intense. See "Risk Factors--Limited Supply of Qualified IT
Professionals."
 
  None of the Company's employees is represented by a collective bargaining
agreement. The Company believes that its relations with its employees are
good.
 
FACILITIES
 
  NetSolve's corporate headquarters are located in a leased facility in
Austin, Texas. In March 1998, the Company relocated all of its operations,
including all employees and the Network Management Center into its current
facility, which covers approximately 70,000 square feet. In connection with
this move, the Company upgraded its 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. The Company's new facility allows
the Company to maintain dual computer rooms with redundant equipment in order
to provide safeguards in the event of a fire or similar emergency.
 
  The lease for NetSolve's offices expires in November 2008 (including a five-
year option to renew). NetSolve believes that its current facilities are
adequate to meet its foreseeable requirements or that suitable additional or
substitute space will be available on commercially reasonable terms.
 
LITIGATION
 
  The Company is not currently a party to any material legal proceedings.

BOARD COMMITTEES
 
  The Board of Directors has two standing committees, an Audit Committee and a
Compensation Committee. The Audit Committee reviews the Company's annual audit
and meets with the Company's independent auditors to review the internal
accounting procedures and financial management practices. The Compensation
Committee recommends to the Board of Directors compensation and benefits for

plans.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  No Compensation Committee member is currently or has been a NetSolve officer

                                      45
<PAGE>
 
serving an equivalent function) of any other entity that has one or more
executive officers serving on NetSolve's Board or Compensation Committee.
 
DIRECTOR COMPENSATION
 
  Directors currently do not receive cash compensation for their services as
directors or members of committees, but are reimbursed for their reasonable
expenses incurred in attending meetings of the Board of Directors. Directors
are eligible to participate in the Company's 1988 Stock Option Plan and Long-
Term Incentive Compensation Plan.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
  NetSolve's 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 for liability (i) for any breach of their duty of loyalty to
the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) for improper payments of dividends or improper stock repurchases or
redemptions as provided in Section 174 of the Delaware General Corporation
Law, or (iv) for any transaction from which the director derived an improper
personal benefit.
 
  NetSolve's Bylaws provide that the Company shall indemnify its directors,
officers, employees and agents to the fullest extent permitted by law. The
Company believes that indemnification under its Bylaws covers at least
negligence and gross negligence on the part of indemnified parties.
 
  NetSolve intends to enter into agreements that indemnify its 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 or on
behalf of NetSolve, arising out of his or her service as a director or
executive officer of NetSolve, any subsidiary of NetSolve or any other company
or enterprise to which the person provides services at NetSolve's request.
NetSolve believes 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
director, officer, employee or agent of the Company in which indemnification
will be required or permitted. The Company is not aware of any threatened
litigation or proceeding that might result in a claim for such
indemnification.

LONG-TERM INCENTIVE COMPENSATION PLAN
 
  The NetSolve, Incorporated Long-Term Incentive Compensation Plan (the "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 NetSolve
in attracting, retaining and motivating executive officers, key employees and
directors and consultants who are essential to NetSolve's 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 the Company or any of its subsidiaries, divisions,
business units or other areas of the Company, 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.
 
  Full-time employees and directors of, and consultants to, NetSolve 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.
 
  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 the Company or shares purchased in the open market.
 
  The Company expects that awards made under the Long-Term Incentive Plan will
be fully deductible for federal income tax purposes. In this connection, if
the Company becomes subject to Section 162(m) of the Internal Revenue Code of
1986, which limits such deductions for awards made to certain covered
participants,
 
                                      48
<PAGE>
 
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 September 30, 1998, options covering an aggregate of 553,324 shares of
common stock had been granted under the Long-Term Incentive Plan at exercise
prices ranging from $2.80 to $7.50. 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-sixteenth of the total amount vesting in each
calendar quarter following the grant. The unvested portion of any exercised
options are subject to a repurchase right of the Company 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 shall 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 shall terminate on December 31, 2006.
 
  Stock Options. The Long-Term Incentive Plan authorizes (i) the grant of
options to purchase common stock intended to qualify as incentive stock
options under Section 422(b) of the Internal Revenue Code of 1986 ("incentive
options") and (ii) the grant of options that do not so qualify ("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 the Company's 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 employees, officers, consultants and directors, whether or
not they are employees of the Company. 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 ("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.
 
  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
 
                                      49
<PAGE>
 
awarded subject to performance criteria or other restrictions which are not
satisfied, are forfeited and must be returned to the Company. 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 the 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 the Company's voting securities; (2) the Company is involved in a merger,
acquisition or similar transaction pursuant to which the Company's directors
immediately before the transaction cease to constitute a majority of the
Company's directors after the transaction; or (3) the Company is involved in a
transaction pursuant to which it is not the surviving corporation, its common
stock is exchanged for, or converted into securities of another entity, it
becomes a subsidiary of another entity, or 50% or more of its aggregate assets
or earning power is sold to another entity.
 
1988 STOCK OPTION PLAN
 
  The NetSolve, Incorporated 1988 Stock Option Plan (the "1988 Option Plan")
was adopted by the Board of Directors and approved by the Company's
stockholders in November 1988. The principal purpose of the 1988 Option Plan
is to advance the interests of the Company and its stockholders by enabling
the Company to attract qualified management and other key personnel and
encourage selected directors, officers and key employees of, and consultants
to, the Company to acquire and retain a proprietary interest in the Company
through the ownership of common stock. A total of 2,601,976 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
plans of the Company 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 September 30, 1998, there were options outstanding under the 1988
Option Plan for 1,908,870 shares of common stock. As of such date, a total of
668,855 shares had been purchased pursuant to option exercises and the Company
had repurchased 6,600 unvested shares pursuant to the provisions of the 1988
Option Plan, leaving an aggregate of 30,851 shares available for future option
grants. No incentive options may 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 "Option Plan Administrator"). The 1988 Option Plan
is currently administered by the Compensation Committee. The Option Plan
Administrator determines the terms of options granted under the 1988 Option
Plan, including the number of 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 the
Company or any parent or subsidiary corporation of the 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.
 
 
                                      50
<PAGE>
 
  The 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 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-sixteenth of the stock
underlying the option vesting in each calendar quarter following the grant.
The unvested portion of exercised options may be repurchased by the Company at
the original exercise price upon termination of employment.
 
  The Company has the authority to amend or terminate the 1988 Option Plan,
except that the Company may not increase the aggregate number of shares which
may be issued under options granted pursuant to the 1988 Option Plan, and no
action may be taken by the Company, 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, the Company established a 401(k) defined
contribution retirement plan (the "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
hire. 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 1998). The Company 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, the Company has not made any contribution to the
Retirement Plan, and does not anticipate making any contribution to the
Retirement Plan in the foreseeable future.
 
BONUS PLAN
 
  In July 1998, the Company adopted a bonus plan (the "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, the Company meets certain financial performance objectives
established from time to time by the Company. The Bonus Plan may be amended or
terminated at any time.

(1) Unless otherwise indicated, the address of each of the individuals named
    above is: c/o NetSolve, Incorporated, 12331 Riata Trace Parkway, Austin,
    TX 78727.
(2) Beneficial ownership is determined in accordance with the rules of the
    Securities and Exchange Commission. Except pursuant to applicable
    community property laws or as indicated in the footnotes of this table, to
    the Company's knowledge, 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 common stock
    subject to options and warrants held by that person that are currently
    exercisable within 60 days of September 30, 1998. 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.
(3) For purposes of this table, the number of shares of common stock
    outstanding prior to the offering is deemed to be 9,680,304, including
    3,285,577 shares of common stock outstanding on September 30, 1998 and an
    additional 6,394,727 shares issuable upon conversion of the Company's
    preferred stock. For purposes of calculating the percentage beneficially
    owned by any person, shares of common stock issuable to such person upon
    the exercise of any options exercisable within 60 days of September 30,
    1998 are also assumed to be outstanding. The number of shares of common
    stock deemed outstanding after this offering includes the additional
    shares being offered by the Company hereby, and assumes no exercise of the
    underwriters' over-allotment option.
(4) Does not give effect to the exercise of the underwriters' over-allotment
    option. If exercised in full, the number of additional shares offered and

<PAGE>
 
                         DESCRIPTION OF CAPITAL STOCK
 
  After this offering, NetSolve's authorized capital stock will consist 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 September 30, 1998, NetSolve had 109 stockholders that owned a total
of 9,680,304 shares of common stock outstanding (including shares issuable
upon conversion of all outstanding preferred stock). Options to purchase an
aggregate of 2,465,444 shares of common stock and warrants to purchase an
aggregate of 167,500 shares of common stock were also outstanding. There will
be      shares of common stock outstanding after this offering (assuming no
exercise of the Underwriter's over-allotment option, and no exercise of
outstanding warrants or options after September 30, 1998) after giving effect
to the sale of the shares of common stock offered in this offering.
 
  Each share of 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 the
Board of Directors. See "Dividend Policy." If NetSolve liquidates or
dissolves, subject to the rights of the holders of outstanding shares of
preferred stock issued in the future, if any, the holders of 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 common stock are, and those to be issued in this
offering will be, fully paid and non-assessable.
 
PREFERRED STOCK
 
  Each share of preferred stock outstanding as of September 30, 1998 will be
converted into one share of common stock and automatically retired upon the
closing of this offering. Thereafter, the Board of Directors is authorized to
issue up to 7,500,000 shares of preferred stock. The 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 NetSolve issues preferred stock, this may delay, defer or prevent a
change in control of NetSolve without further stockholder action. The issuance
of preferred stock with voting and conversion rights may adversely affect the
voting power of the holders of common stock, including voting rights, of the
holders of common stock. In certain circumstances, the market price of the
common stock may decrease as a result. As of the closing of this offering, no
shares of preferred stock will be outstanding and NetSolve currently has no
plans to issue any shares of preferred stock.
 
WARRANTS
 
  As of September 30, 1998, NetSolve had outstanding exercisable warrants to
purchase 167,500 shares of common stock with a weighted average exercise price
of $2.72 per share. These warrants will expire between 1998 and 1999.
 
REGISTRATION RIGHTS
 
  Following this offering, the holders of       shares of common stock (the
"Registrable Securities") 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 the Company
and the holders of the Registrable Securities. The holders of at least 30% of
the Registrable Securities may generally require that the Company register the
Registrable Securities for public resale. If NetSolve registers any of its
common stock,
 
                                      55
<PAGE>
 
either for its own account or for the account of other security holders, the
holders of Registrable Securities are entitled to include their Registrable
Securities 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 the Registrable Securities may also require NetSolve (not more than one
time in any 12-month period) to register all or a portion of their Registrable
Securities 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. The
registration rights of each holder of Registerable Securities terminate at the
earlier of: (a) such time as the holder may, within a three-month period,
offer and sell all of his Registerable Securities pursuant to Rule 144 under
the Securities Act without any adverse effect on the price at which such
Registerable Securities 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 CERTAIN CHARTER PROVISIONS
 
  Certain provisions of Delaware law and NetSolve's restated certificate of
incorporation could complicate NetSolve's 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 NetSolve management and
those persons seeking control. NetSolve believes it is more advantageous to
protect its potential ability to negotiate, rather than discourage, unfriendly
or unsolicited third parties attempting to acquire or restructure NetSolve.
Among other things, negotiating such proposals could result in an improvement
of their terms.
 
  NetSolve is 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
NetSolve without the stockholders taking further action.
 
  It is more difficult for NetSolve's existing stockholders to replace the
Board of Directors as well as for another party to obtain control of NetSolve
by replacing the Board of Directors because cumulative voting is eliminated.
The 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 the Board of Directors.
In addition, these provisions could have the effect of making it more
difficult for a third party to acquire, or of discouraging a third party from
attempting to acquire, a majority of NetSolve's outstanding voting stock. See
"Risk Factors--Anti-Takeover Provisions."
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar for the Common Stock is Chase Mellon
Shareholder Services, L.L.C.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  There has not been any public market for NetSolve's common stock prior to
this offering. Future sales of substantial amounts of common stock in the
public market could adversely affect prevailing market prices from time to
time. Furthermore, only a limited number of shares will be available for sale
shortly after this offering because of certain resale restrictions (as
described below), and sales of substantial amounts of the common stock in the
public market after the restrictions lapse could adversely affect the
prevailing market price and NetSolve's ability to raise equity capital in the
future.
 
  Upon completion of this offering, based on the number of shares outstanding
as of September 30, 1998, NetSolve will have outstanding an aggregate of
shares of common stock (assuming no exercise of warrants or options to
purchase common stock outstanding as of September 30, 1998). Of these shares,
the     shares sold in this offering will be freely tradable without
restriction or further registration under the Securities Act, unless such
shares are purchased by an existing "affiliate" of NetSolve as that term is
defined in Rule 144 under the Securities Act (an "Affiliate"). The remaining
shares of common stock held by existing stockholders are "restricted
securities" as that term is defined in Rule 144 under the Securities Act
("Restricted Shares"). After 180 days from the date of this Prospectus (the
"Lock-up Period"): (1)     of the Restricted Shares will be eligible for
immediate sale without restriction under Rules 144(k) or 701 under the
Securities Act, (2)     of the Restricted Shares will be eligible for sale
subject to compliance with the volume and other restrictions of Rule 144, and
(3)     of the Restricted Shares will become eligible for sale at various
times after the Lock-up Period upon expiration of applicable holding periods
under Rule 144, subject in some cases to the volume and other restrictions of
Rule 144. In addition, as of September 30, 1998, there were outstanding
2,465,444 options and 167,500 warrants to purchase shares of the Company and
all of such options and warrants will be subject to 180-day lock-up
agreements. After the Lock-up Period, all of the warrants will be exercisable
and     of such options will be vested and exercisable.
 
  All of NetSolve's officers and directors and certain stockholders have
entered into lock-up agreements. These agreements generally provide that they
will not offer, pledge, sell, offer to sell, contract to sell, sell any option
or contract to purchase, purchase any option to sell, grant any option, right
or warrant to purchase, or otherwise transfer or dispose of, directly or
indirectly, any of the shares of common stock or any securities convertible
into, or exercisable or exchangeable for, common stock owned by them.
Additionally, the lock-up agreements provide that these stockholders will not
enter into any swap or other arrangement that transfers to another, in whole
or in part, any of the economic consequences of ownership of the common stock,
or any securities convertible into, or exercisable or exchangeable for, shares
of common stock, for a period of 180 days after the date of this Prospectus,
without the prior written consent of BancBoston Robertson Stephens, subject to
certain limited exceptions. BancBoston Robertson Stephens may, in its sole
discretion and at any time without notice, release all or any portion of the
securities subject to lock-up agreements. BancBoston Robertson Stephens
currently has no plans to release any portion of the securities subject to
lock-up agreements. When determining whether or not to release shares from the
lock-up agreements, BancBoston Robertson Stephens will consider, among other
factors, the stockholder's reasons for requesting the release, the number of
shares for which the release is being requested and market conditions at the
time.
 
  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 any prior owner except an Affiliate) would be entitled
to sell within any three-month period a number of shares that does not exceed
the greater of: (i) one percent of the number of shares of common stock then
outstanding (which will equal approximately     shares immediately after this
offering); or (ii) the average weekly trading volume of the common stock on
the Nasdaq National Market during the four calendar weeks preceding the filing
of a notice on Form 144 with respect to such sale. Sales under Rule 144 are
also subject to certain manner of sale provisions, notice requirements and to
the availability of current public information about the Company. 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
 
                                      57
<PAGE>
 
for at least two years (including the holding period of any prior owner except
an Affiliate), is entitled to sell such shares without complying with the
manner of sale, public information, volume limitation or notice provisions of
Rule 144. Accordingly, unless otherwise restricted, "144(k) shares" may be
sold immediately upon the completion of this offering.
 
  Subject to certain limitations on the aggregate offering price of a
transaction and other conditions, Rule 701 may be relied upon with respect to
the resale of securities originally purchased from the Company by its
employees, directors, officers, consultants or advisors prior to the date the
issuer becomes subject to the reporting requirements of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), pursuant to written
compensatory benefit plans or written contracts relating to the compensation
of such persons. In addition, the Securities and Exchange Commission has
indicated that Rule 701 will apply to typical stock options granted by an
issuer before it becomes subject to the reporting requirements of the Exchange
Act, along with the shares acquired upon exercise of such options (including
exercises after the date of this Offering). Securities issued in reliance on
Rule 701 are restricted securities and, subject to the contractual
restrictions described above, beginning 90 days after the date of this
prospectus, may be sold by: (i) persons other than Affiliates, subject only to
the manner of sale provisions of Rule 144 and (ii) Affiliates, under Rule 144
without compliance with its one-year minimum holding period requirements.
 
  Approximately 90 days after the completion of this offering, NetSolve
intends to file a registration statement under the Securities Act covering
approximately     shares of common stock, subject to outstanding options or
reserved for issuance under the Company's Long-Term Incentive Plan and 1988
Option Plan. See "Management--Long-Term Incentive Compensation Plan" and "--
1988 Stock Option Plan." Accordingly, shares registered under such
registration statement will, subject to Rule 144 volume limitations applicable
to Affiliates, be available for sale in the open market, except to the extent
that such shares are subject to vesting restrictions with the Company.
 
  Upon completion of this offering, the holders of approximately     shares of
Registrable Securities or the transferees will be entitled to certain rights
with respect to registration of such shares under the Securities Act.
Registration of such shares under the Securities Act would result in such
shares becoming freely tradable without restriction under the Securities Act
(except for shares purchased by Affiliates) immediately upon the effectiveness
of such registration. See "Description of Capital Stock--Registration Rights."

  The underwriters named below (the "Underwriters"), acting through their

(the "Representatives"), have severally agreed with NetSolve and certain
stockholders of the Company (the "Selling Stockholders"), subject to the terms
and conditions of the Underwriting Agreement, to purchase from NetSolve and
the Selling Stockholders the number of shares of common stock set forth
opposite their names below. The Underwriters are committed to purchase and pay
for all such shares if any are purchased.

  The Company and the Selling Stockholders have been advised by the
Representatives that the Underwriters propose to offer the shares of common
stock to the public at the initial 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 the initial public 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 the
Company and the Selling Stockholders as set forth on the cover page of this
Prospectus.
 
  The Company and certain Selling Stockholders have granted to the
Underwriters an option, exercisable during the 30-day period after the date of
this Prospectus, to purchase up to     additional shares of common stock at
the same price per share as the Company and the Selling Stockholders will
receive for the     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     shares offered hereby. If purchased, such additional shares will be
sold by the Underwriters on the same terms as those on which the     shares
are being sold. The Company 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, the Company 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.
 
  Each officer and director who holds shares of the Company and certain other
holders of shares of common stock have agreed, for the Lock-up Period, subject
to certain exceptions, not to offer to sell, contract to sell, or otherwise
sell, dispose of, loan, pledge or grant any rights with respect to any shares
of common stock, any options or warrants to purchase any shares of common
stock, or any securities convertible into or exchangeable for shares of common
stock owned as of the date of this Prospectus or thereafter acquired directly
by such
 
                                      59
<PAGE>
 
holders or with respect to which they have the power of disposition, without
the prior written consent of BancBoston Robertson Stephens. However,
BancBoston Robertson Stephens may, in its sole discretion and at any time
without notice, release all or any portion of the securities subject to lock-
up agreements. There are no existing agreements between the Representatives
and any of the Company's stockholders providing consent to the sale of shares
prior to the expiration of the Lock-up Period. In addition, the Company has
agreed that during the Lock-up Period the Company will not, without the prior
written consent of BancBoston Robertson Stephens, subject to certain
exceptions, (i) consent to the disposition of any shares held by stockholders
subject to lock-up agreements prior to the expiration of the Lock-up Period or
(ii) 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 the Company's sale of shares in this offering, the
issuance of common stock upon the exercise of outstanding options, and the
Company's issuance of options and shares under existing stock option and
incentive plans. See "Shares Eligible for Future Sale."
 
  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 the common
stock. Consequently, the initial public offering price for the common stock
offered by this Prospectus will be determined through negotiations among the
Company, the Selling Stockholders and the Representatives. Among the factors
to be considered in such negotiations are prevailing market conditions,
certain financial information of the Company, market valuations of other
companies that the Company and the Representatives believe to be comparable to
the company, estimates of the business potential of the Company, the present
state of the Company's development and other factors deemed relevant.
 
  The Representatives have advised the Company 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 the Company that such
transactions may be effected on the Nasdaq National Market or otherwise and,
if commenced, may be discontinued at any time.
 
                                 LEGAL MATTERS

Company and the Selling Stockholders by Worsham, Forsythe & Wooldridge,
L.L.P., Dallas, Texas. Certain legal matters will be passed upon for the

               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, 1997 and 1998, 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, 1998. 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 financial position of NetSolve,
Incorporated, at March 31, 1997 and 1998, and the results of their operations
and their cash flows for each of the three years in the period ended March 31,
1998, in conformity with generally accepted accounting principles.

1. ORGANIZATION AND DESCRIPTION OF THE COMPANY
 
  NetSolve, Incorporated, a Delaware corporation, (the "Company") engages in
the business of providing enterprise data networking management services
within the U.S. These services include network design, installation and
implementation coordination, and ongoing network management. The Company also
resells data networking equipment manufactured by selected leading suppliers
of these products. The Company's services are designed to allow its clients to
selectively outsource, or "out-task" network specific tasks in order to
migrate to new technology, increase network reliability, and reduce overall
network costs.
 
  The Company also previously provided data transport services to clients.
These services consisted of Private Line and Frame Relay networks (using the
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.
 
 Income Taxes
 
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards (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 1,222,301, 1,317,224 and 1,265,861 in 1996, 1997 and
1998, respectively, and 1,303,283 and 1,469,727 for the six months ended
September 30, 1997 and 1998, respectively. For all periods presented,
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 loss from continuing operations is as follows:

 Revenue Recognition
 
  Network management services revenues are recognized in the period services
are provided based upon rates established by contract. Equipment revenues are
recognized in the period the equipment is shipped to the customer or upon
installation, depending on contract terms. Other revenues which consist
primarily of equipment maintenance services are recognized in the period
services are provided.

 Advertising Costs
 
  The Company expenses advertising costs as incurred. Advertising expense for
the years ended March 31, 1996, 1997 and 1998 and the six months ended
September 30, 1997 and 1998 was approximately $159,000, $242,000, $370,000,
$185,000 and $207,000, 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 one reseller customer of
the Company's services represented 47% of the outstanding accounts receivable
balance at March 31, 1998.

accounts for 1996, 1997 and 1998 (in thousands):

 Concentrations of Revenues
 
  Revenues from one reseller customer of the Company's services amounted to
52% of the Company's net revenues for the year ended March 31, 1998. The
Company currently is providing three different services to this customer 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 through December 1999,
will be renewed or replaced.
 
 Comprehensive Income (Loss)
 
  In June 1997, the Financial Accounting Standards Board issued SFAS 130,
Reporting Comprehensive Income. The Company adopted SFAS 130 in the six months
ended September 30, 1998. 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. SFAS 131
is effective for fiscal years beginning after December 15, 1997, but is not
required for interim disclosure in the first year of adoption. The Company
expects that implementation of this standard will not have a material effect
on its financial disclosures.
 
 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. Had
the conversion of the redeemable convertible preferred stock occurred on April
1, 1997, basic and diluted net income (loss) per share would have been $(0.24)
and $(0.01) for the year ended March 31, 1998 and for the six months ended
September 30, 1998, respectively.
 
 Unaudited Interim Results
 
  The accompanying consolidated balance sheet as of September 30, 1998, the
consolidated statements of operations and cash flows for the six months ended
September 30, 1997 and 1998 and the consolidated statements of stockholders'
equity (deficit) for the six months ended September 30, 1998 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 six
months ended September 30, 1998 are not necessarily indicative of the results
that may be expected for the year ending March 31, 1999.
 
 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 the Private Line
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 the Private Line 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 and $715,000 in fiscal years 1997 and
1998, 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 Frame Relay
services resold by the Company, and its obligations under a supplier contract,
effective October 1, 1997 to NetPlus, Inc. The purchase price was 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. The Company has an ongoing obligation to provide
maintenance and management services, coordination of the telecommunications
provisioning requirements, and billing and collection services for the sold
customer base for a nominal fee over a term of 42 months. Management believes
the sale or assignment of this portion of the transport business segment will
have no material financial impact beyond March 31, 1998, and accordingly has
not made any provision in the accompanying financial statements. 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 $18,408,000,
$13,223,000 and $1,072,000 for the years ended March 31, 1996, 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:

   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 $2.614 to $2.763 at March 31, 1998
and an aggregate redemption price of $26,541,000.
 
  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 September 30, 1998). 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 $.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 except that the
Board of Directors' option to redeem the Series B redeemable convertible
preferred stock prior to March 31, 1999 requires the consent of at least two-
thirds of the then outstanding shares of the Series B 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 $1.986 to $2.155 at March 31, 1998
and an aggregate redemption price of $15,074,000. 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, 1998, total outstanding options subject to repurchase rights were
543,524.
 
 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, 1998, 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
the Company's Board of Directors, which consists entirely of outside
directors. Regular, full-time employees of the Company, as well as 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 600,000. 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. There were approximately 47,000 options granted under
this plan during the fiscal year ended March 31, 1998.
 
  The Company has also granted non-qualified options other than pursuant to
the above plans. None of these options were exercised in fiscal 1998. At March
31, 1998, such options outstanding totaled 3,250 shares representing grants to
two outside directors at exercise prices of $.80 and $1.20 per share.
 
  At March 31, 1998 the Company had reserved 2,563,593 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 these
options was estimated as of the date of grant using a minimum value option
pricing model with

weighted-average risk free interest rates for 1996, 1997, 1998 and the six
months ended September 30, 1998 of 6.01%, 6.45%, 5.69% and 5.55%,
respectively; no dividends; and a weighted-average expected life of the option
of five years.
 
  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:

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 as of March 31 are as follows:

which were not benefited. The valuation allowance decreased by approximately
$3,671,000 during the year ended March 31, 1997.

  As of March 31, 1998, the Company had federal net operating loss
carryforwards of approximately $18,222,000 which will expire beginning in
2004, if not utilized. The Company has alternative minimum tax credit
carryforwards of $177,000 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.

  The tax benefit attributed to continuing operations in each of the years
ended March 31, 1996, 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 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, 1998, the Company had purchased irrevocable letters of credit
totaling $645,000 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 is required to purchase an irrevocable letter of credit which it
intends to collateralize with a certificate of deposit in the amount of
$1,000,000. The requirement for the letter of credit extends through the
earlier of the expiration of the lease (November 2003) or four consecutive
quarters of profitability.

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 the
Company, the Selling Stockholders and the Underwriters, filed as Exhibit 1.1
to this Registration Statement, for a description of indemnification
arrangements between the Company, 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 various unaffiliated entities
and individuals 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

to Section 4(2) on the basis that the transactions did not involve public
offerings.

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

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

                                  SIGNATURES
 
  Pursuant to the requirements of the Securities Act of 1933, the undersigned

   2.  Representations, Warranties and Agreements of the Company and the Selling
       -------------------------------------------------------------------------
       Stockholders.
       ------------ 

       I.  The Company represents and warrants to and agrees with each
Underwriter and each Selling Stockholder that:

           (a) A registration statement on Form S-1 (File No. 333-_________)
   with respect to the Shares, including a prospectus subject to completion, has
   been prepared by the Company in conformity in all material respects with the
   requirements of the Securities Act of 1933, as amended (the "Act"), and the
   applicable rules and regulations (the "Rules and Regulations") of the
   Securities and Exchange Commission (the "Commission") under the Act and has
   been filed with the Commission; such amendments to such registration
   statement, such amended prospectuses subject to completion and such
   abbreviated registration statements pursuant to Rule 462(b) of the Rules and
   Regulations as may have been required prior to the date hereof have been
   similarly prepared and filed with the Commission; and the Company will file
   such additional amendments to such registration statement, such amended
   prospectuses subject to completion and such abbreviated registration
   statements as may hereafter be required.  Copies of such registration
   statement and amendments, of each related prospectus subject to completion
   (the "Preliminary Prospectuses") and of any abbreviated registration
   statement pursuant to Rule 462(b) of the Rules and Regulations have been
   delivered to you.

           If the registration statement relating to the Shares has been
   declared effective under the Act by the Commission, the Company will prepare
   and promptly file with the Commission the information omitted from the
   registration statement pursuant to Rule 430A(a) or, if BancBoston Robertson
   Stephens Inc., on behalf of the several Underwriters, shall agree to the
   utilization of Rule 434 of the Rules and Regulations, the information
   required to be included in any term sheet filed pursuant to Rule 434(b) or
   (c), as applicable, of the Rules and Regulations pursuant to subparagraph
   (1), (4) or (7) of Rule 424(b) of the Rules and Regulations or as part of a
   post-effective amendment to the registration statement (including a final
   form of prospectus).  If the registration statement relating to the Shares
   has not been declared effective under the Act by the Commission, the Company
   will prepare and promptly file an amendment to the registration statement,
   including a final form of prospectus, or, if BancBoston Robertson Stephens
   Inc., on behalf of the several Underwriters, shall agree to the utilization
   of Rule 434 of the Rules and Regulations, the information required to be
   included in any term sheet filed pursuant to Rule 434(b) or (c), as
   applicable, of the Rules and Regulations.  The term "Registration Statement"
   as used in this Agreement shall mean such registration statement, including
   financial statements, schedules and exhibits, in the amended form in which it
   became or becomes, as the case may be, effective (including, if the Company
   omitted information from the registration statement pursuant to Rule 430A(a)
   or files a term sheet pursuant to Rule 434 of the Rules and Regulations, the
   information deemed to be a part of the registration statement at the time it
   became effective pursuant to Rule 430A(b) or Rule 434(d) of the Rules and
   Regulations) and, in the event of any amendment thereto or the filing of any
   abbreviated registration statement pursuant to Rule 462(b) of the Rules and
   Regulations relating thereto after the effective date of such registration
   statement, shall also mean (from and after the effectiveness of such
   amendment or the filing of such abbreviated registration statement) such
   registration statement as so amended, together with any such abbreviated
   registration statement.  The term "Prospectus" as used in this Agreement
   shall mean the prospectus relating to the Shares as included in such
   Registration Statement at the time it becomes effective (including, if the
   Company omitted information from the Registration Statement pursuant to Rule
   430A(a) of the Rules and Regulations, the information deemed to be a part of
   the Registration Statement at the time it became effective pursuant to Rule
   430A(b) of the Rules and Regulations); provided, however, that if in reliance
   on Rule 434 of the Rules and Regulations and with the consent of BancBoston
   Robertson Stephens Inc., on behalf of the several Underwriters, the Company
   shall 

                                       2
<PAGE>
 
   have provided to the Underwriters a term sheet pursuant to Rule 434(b) or
   (c), as applicable, prior to the time that a confirmation is sent or given
   for purposes of Section 2(10)(a) of the Act, the term "Prospectus" shall mean
   the "prospectus" subject to completion" (as defined in Rule 434(g) of the
   Rules and Regulations) last provided to the Underwriters by the Company and
   circulated by the Underwriters to all prospective purchasers of the Shares
   (including the information deemed to be a part of the Registration Statement
   at the time it became effective pursuant to Rule 434(d) of the Rules and
   Regulations). Notwithstanding the foregoing, if any revised prospectus shall
   be provided to the Underwriters by the Company for use in connection with the
   offering of the Shares that differs from the prospectus referred to in the
   immediately preceding sentence (whether or not such revised prospectus is
   required to be filed with the Commission pursuant to Rule 424(b) of the Rules
   and Regulations), the term "Prospectus" shall refer to such revised
   prospectus from and after the time it is first provided to the Underwriters
   for such use. If in reliance on Rule 434 of the Rules and Regulations and
   with the consent of BancBoston Robertson Stephens Inc., on behalf of the
   several Underwriters, the Company shall have provided to the Underwriters a
   term sheet pursuant to Rule 434(b) or (c), as applicable, prior to the time
   that a confirmation is sent or given for purposes of Section 2(10)(a) of the
   Act, the Prospectus and the term sheet, together, will not be materially
   different from the prospectus in the Registration Statement.

           (b) The Commission has not issued any order preventing or suspending
   the use of any Preliminary Prospectus or instituted proceedings for that
   purpose.  Each Preliminary Prospectus has conformed in all material respects
   to the requirements of the Act and the Rules and Regulations and, as of its
   date, has not included any untrue statement of a material fact or omitted to
   state a material fact necessary to make the statements therein, in the light
   of the circumstances under which they were made, not misleading.  At the time
   the Registration Statement became or becomes, as the case may be, effective
   and at all times subsequent thereto up to and on the Closing Date (as defined
   in Section 3) and on any later date on which Option Shares are to be
   purchased:  (i) the Registration Statement and the Prospectus, and any
   amendments or supplements thereto, contained and will contain all material
   information required to be included therein by the Act and the Rules and
   Regulations and will in all material respects conform to the requirements of
   the Act and the Rules and Regulations; (ii) the Registration Statement, and
   any amendments or supplements thereto, did not and will not include any
   untrue statement of a material fact or omit to state a material fact required
   to be stated therein or necessary to make the statements therein not
   misleading; and (iii) the Prospectus, and any amendments or supplements
   thereto, did not and will not include any untrue statement of a material fact
   or omit to state a material fact necessary to make the statements therein, in
   the light of the circumstances under which they were made, not misleading.
   Notwithstanding the foregoing, none of the representations and warranties
   contained in this subparagraph (b) shall apply to information contained in or
   omitted from the Registration Statement or Prospectus, or any amendment or
   supplement thereto, in reliance upon, and in conformity with, written
   information relating to any Underwriter furnished to the Company by such
   Underwriter specifically for use in the preparation thereof.

           (c) Each of the Company and its subsidiaries has been duly
   incorporated and is validly existing as a corporation in good standing under
   the laws of the jurisdiction of its incorporation, with all requisite
   corporate power and authority to own, lease and operate its properties and
   conduct its business as described in the Prospectus; the Company owns all of
   the outstanding capital stock of its subsidiaries free and clear of any
   pledge, lien, security interest, encumbrance, claim or equitable interest.
   Each of the Company and its subsidiaries is duly qualified to do business as
   a foreign corporation and is in good standing in each jurisdiction in which

   all of which requirements have been satisfied in all material respects.

           (e) There is not any pending or, to the Company's knowledge,
   threatened action, suit, claim or proceeding against the Company, either of
   its subsidiaries or any of their respective officers or any of their
   respective properties, assets or rights before any court, government or
   governmental agency or body, domestic or foreign, having jurisdiction over

   been accurately described in all material respects in the Registration
   Statement or Prospectus or filed as exhibits to the Registration Statement.

           (f) All outstanding shares of capital stock of the Company (including
   the Selling Stockholder Shares) have been duly authorized and validly issued
   and are fully paid and nonassessable, have been issued in compliance with all
   federal and state securities laws, were not issued in violation of or subject
   to any preemptive rights or other rights to subscribe for or purchase
   securities, and the authorized and outstanding capital stock of the Company
   is as set forth in the Prospectus under the caption "Capitalization" and
   conforms in all material respects to the statements relating thereto
   contained in the Registration Statement and the Prospectus (and such
   statements correctly state the substance of the instruments defining the
   capitalization of the Company).  The Shares to be purchased from the Company
   hereunder have been duly authorized for issuance and sale to the Underwriters
   pursuant to this Agreement and, when issued and delivered by the Company
   against payment therefor in accordance with the terms of this Agreement, will
   be duly and validly issued and fully paid and nonassessable, and will be sold
   free and clear of any pledge, lien, security interest, encumbrance, claim or
   equitable interest.  No preemptive right, co-sale right, registration right,
   right of first refusal or other similar right of stockholders exists with
   respect to any of the Shares to be purchased from the Company hereunder or
   the issuance and sale thereof other than those that have been expressly
   waived prior to the date hereof and those that will automatically expire upon

   the Closing Date.  No further approval or authorization of any stockholder,
   the Board of Directors of the Company or others is required for the issuance
   and sale or transfer of the Shares except as may be required under the Act,
   the Exchange Act or under state or other securities or Blue Sky laws.  Except
   as disclosed in the Prospectus and the financial statements of the Company,

   purchase, any securities or obligations convertible into, or any contracts or
   commitments to issue or sell, shares of its capital stock or any such
   options, rights, convertible securities or obligations.  The description of
   the Company's stock option, stock bonus and other stock plans or
   arrangements, and the options or other rights granted and exercised
   thereunder, set forth in the Prospectus accurately and fairly presents the
   information required to be shown with respect to such plans, arrangements,
   options and rights in all material respects.

   (ii) the agreements to which the Company or either of its subsidiaries is a
   party described in the Registration Statement and Prospectus are valid

   Company's knowledge, the other contracting party or parties thereto are not
   in material breach or material default under any of such agreements, and

   by similar companies in similar businesses, including insurance covering real
   and personal property owned or leased by the Company against theft, damage,
   destruction, acts of vandalism and all other risks customarily insured
   against, all of which insurance is in full force and effect.  The Company
   does not have any reason to believe that it will not be able to renew its
   existing insurance coverage as and when such coverage expires or to obtain
   similar coverage from similar insurers as may be necessary to continue its
   business at a cost that would not materially and adversely affect the

   knowledge of, any infringement of or conflict with asserted rights of others
   with respect to any patent, patent rights, inventions, trade secrets, know-
   how, trademarks, service marks, trade names or copyrights that, singly or in

   Stockholder, will have valid marketable title to the Shares to be sold by
   such Selling Stockholder, free and clear of any pledge, lien, security

   delivered, in the form heretofore furnished to the Representatives, an
   irrevocable Power of Attorney (the "Power of Attorney") appointing Craig S.

<PAGE>
 
   Power of Attorney and the Custody Agreement constitutes a valid and binding
   agreement on the part of such Selling Stockholder, enforceable in accordance
   with its terms, except as the enforcement thereof may be limited by
   applicable bankruptcy, insolvency, reorganization, moratorium or other laws
   relating to or affecting creditors' rights generally or by general equitable

   powers with respect thereto, to accept payment therefor, and otherwise to act
   on behalf of such Selling Stockholder in connection with this Agreement.

           (c) All consents, approvals, authorizations and orders required for
   the execution and delivery by such Selling Stockholder of the Power of
   Attorney and the Custody Agreement, the execution and delivery by or on
   behalf of such Selling Stockholder of this Agreement and the sale and
   delivery of the Shares to be sold by such Selling Stockholder under this
   Agreement (other than, at the time of the execution hereof (if the
   Registration Statement has not yet been declared effective by the
   Commission), the issuance of the order of the Commission declaring the
   Registration Statement effective and such consents, approvals, authorizations
   or orders as may be necessary under state or other securities or Blue Sky
   laws) have been obtained and are in full force and effect.  Such Selling
   Stockholder, if other than a natural person, has been duly organized and is
   validly existing in good standing under the laws of the jurisdiction of its
   organization as the type of entity that it purports to be.  Such Selling
   Stockholder has full legal right, power and authority to enter into and
   perform its obligations under this Agreement and such Power of Attorney and
   Custody Agreement, and to sell, assign, transfer and deliver the Shares to be
   sold by such Selling Stockholder under this Agreement.

           (d) Such Selling Stockholder will not, during the Lock-Up Period,
   effect the Disposition of any Securities now owned or hereafter acquired
   directly by such Selling Stockholder or with respect to which such Selling
   Stockholder has or hereafter acquires the power of disposition, otherwise
   than (i) as a bona fide gift, provided that the donees thereof agree in
   writing to be bound by this restriction, or (ii) with the prior written
   consent of BancBoston Robertson Stephens Inc.  The foregoing restriction is
   expressly agreed to preclude the holder of the Securities from engaging in
   any hedging or other transaction which is designed to or reasonably expected
   to lead to or result in a Disposition of Securities during the Lock-Up
   Period, even if such Securities would be disposed of by someone other than
   the Selling Stockholder.  Such prohibited hedging or other transactions would
   include any short sale (whether or not against the box) or any purchase, sale
   or grant of any right (including any put or call option) with respect to any
   Securities or with respect to any security (other than a broad-based market
   basket or index) that includes, relates to or derives any significant part of
   its value from the Securities.  Notwithstanding the foregoing, this
   restriction shall not prohibit (i) the sale of Shares to the Underwriters
   pursuant to this Agreement or (ii) resales of shares of Common Stock acquired
   either in the public offering to which the Registration Statement relates or
   in subsequent open-market purchases.  Such Selling Stockholder also agrees
   and consents to the entry of stop transfer instructions with the Company's
   transfer agent against the transfer of Securities held by such Selling
   Stockholder except in compliance with this restriction.

           (e) Certificates in negotiable form for all Shares to be sold by such
   Selling Stockholder under this Agreement, together with a stock power or
   powers duly endorsed in blank by such Selling Stockholder, have been placed

           (f) This Agreement has been duly authorized by each Selling
   Stockholder that is not a natural person and has been duly executed and
   delivered by or on behalf of such Selling Stockholder and is a valid and
   binding agreement of such Selling Stockholder, enforceable in accordance with

   3.  Purchase, Sale and Delivery of Shares.  On the basis of the
       -------------------------------------                      
representations, warranties and agreements herein contained, but subject to the
terms and conditions herein set forth, the Company and the Selling Stockholders
agree, severally and not jointly, to sell to the Underwriters, and each
Underwriter agrees, severally and not jointly, to purchase from the Company and
the Selling Stockholders, respectively, at a purchase price of $_____ per share,
the respective number of Company Shares as hereinafter set forth and Selling
Stockholder Shares set forth opposite the names of the Company and the Selling
Stockholders in Schedule B hereto.  The obligation of each Underwriter to the
Company and to each Selling Stockholder shall be to purchase from the Company or
such Selling Stockholder that number of Company Shares or Selling Stockholder
Shares, as the case may be, which (as nearly as practicable, as determined by
you) is in the same proportion to the number of Company Shares or Selling
Stockholder Shares, as the case may be, set forth opposite the name of the
Company or such Selling Stockholder in Schedule B hereto as the number of Firm
Shares that is set forth opposite the name of such Underwriter in Schedule A
hereto (subject to adjustment as provided in Section 10) is to the total number
of Firm Shares to be purchased by all the Underwriters under this Agreement.

       The certificates in negotiable form for the Selling Stockholder Shares
have been placed in custody (for delivery under this Agreement) under the
Custody Agreement.  Each Selling Stockholder agrees that the certificates for
the Selling Stockholder Shares of such Selling Stockholder so held in custody
are subject to the interests of the Underwriters hereunder, that the
arrangements made by such Selling Stockholder for such custody, including the
Power of Attorney is to that extent irrevocable and that the obligations of such
Selling Stockholder hereunder shall not be terminated by the act of such Selling
Stockholder or by operation of law, whether by the death or incapacity of such
Selling Stockholder or the occurrence of any other event, except as specifically
provided herein or in the Custody Agreement.  If any Selling Stockholder should
die or be incapacitated, or if any other such event should occur, before the
delivery of the certificates for the Selling Stockholder Shares hereunder, the
Selling Stockholder Shares to be sold by such Selling Stockholder shall, except
as specifically provided herein or in the Custody Agreement, be delivered by the
Custodian in accordance with the terms and conditions of this Agreement as if
such death, incapacity or other event had not occurred, regardless of whether
the Custodian shall have received notice of such death or other event.

       Delivery of definitive certificates for the Firm Shares to be purchased
by the Underwriters pursuant to this Section 3 shall be made against payment of
the purchase price therefor by the several 

                                       12
<PAGE>
 
Underwriters by certified or official bank check or checks drawn in same-day
funds or by wire transfer of same-day funds, payable to the order of the Company
with regard to the Shares being purchased from the Company, and to the order of
the Custodian for the respective accounts of the Selling Stockholders with
regard to the Shares being purchased from such Selling Stockholders, at the
offices of Worsham, Forsythe & Wooldridge, L.L.P., 1601 Bryan Street, Suite
3000, Dallas, Texas 75201 (or at such other place as may be agreed upon among
the Representatives, the Company and the Attorneys), at 7 A.M., San Francisco
time (a) on the third full business day following the first day that Shares are
traded, (b) if this Agreement is executed and delivered after 1:30 P.M., San
Francisco time, the fourth full business day following the day that this
Agreement is executed and delivered or (c) at such other time and date not later
than seven full business days following the first day that Shares are traded as
the Representatives, the Company and the Attorneys may determine (or at such
time and date to which payment and delivery shall have been postponed pursuant
to Section 10), such time and date of payment and delivery being herein called
the "Closing Date"; provided, however, that if the Company has not made
available to the Representatives copies of the Prospectus within the time
provided in Section 4(d), the Representatives may, in their sole discretion,
postpone the Closing Date until no later than two full business days following
delivery of copies of the Prospectus to the Representatives. The certificates
for the Firm Shares to be so delivered will be made available to you at such
office or such other location including, without limitation, in New York City,
as you may reasonably request for checking at least one full business day prior
to the Closing Date and will be in such names and denominations as you may
request, such request to be made at least two full business days prior to the
Closing Date. If the Representatives so elect, delivery of the Firm Shares may
be made by credit through full fast transfer to the accounts at The Depository
Trust Company designated by the Representatives.

       It is understood that you, individually, and not as the Representatives
of the several Underwriters, may (but shall not be obligated to) make payment of
the purchase price on behalf of any Underwriter or Underwriters whose check or
checks shall not have been received by you prior to the Closing Date for the
Firm Shares to be purchased by such Underwriter or Underwriters.  Any such
payment by you shall not relieve any such Underwriter or Underwriters of any of
its or their obligations hereunder.

       After the Registration Statement becomes effective, the several
Underwriters intend to make an initial public offering (as such term is
described in Section 11) of the Firm Shares at an initial public offering price
of $____ per share.  After the initial public offering, the several Underwriters
may, in their discretion, vary the public offering price.

       The information set forth in the second sentence of the last paragraph on

the Prospectus constitutes the only information furnished by the Underwriters to
the Company for inclusion in any Preliminary Prospectus, the Prospectus or the
Registration Statement, and you, on behalf of the respective Underwriters,
represent and warrant to the Company and the Selling Stockholders that the
statements made therein do not include any untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

   4.  Further Agreements of the Company.  The Company agrees with the several
       ---------------------------------                                      
Underwriters that:

       (a) The Company will use its best efforts to cause the Registration
   Statement and any amendment thereof, if not effective at the time and date
   that this Agreement is executed and delivered by the parties hereto, to
   become effective as promptly as possible.  The Company will use its best

                                       13
<PAGE>
 
   efforts to cause any abbreviated registration statement pursuant to Rule
   462(b) of the Rules and Regulations as may be required subsequent to the date
   the Registration Statement is declared effective to become effective as
   promptly as possible.  The Company will notify you, promptly after it shall
   receive notice thereof, of the time when the Registration Statement, any
   subsequent amendment to the Registration Statement or any abbreviated
   registration statement has become effective or any supplement to the
   Prospectus has been filed.  If the Company omitted information from the
   Registration Statement at the time it was originally declared effective in
   reliance upon Rule 430A(a) of the Rules and Regulations, the Company will
   provide evidence satisfactory to you that the Prospectus contains such
   information and has been filed, within the time period prescribed, with the
   Commission pursuant to subparagraph (1) or (4) of Rule 424(b) of the Rules
   and Regulations or as part of a post-effective amendment to such Registration
   Statement as originally declared effective that is declared effective by the
   Commission.  If the Company files a term sheet pursuant to Rule 434 of the
   Rules and Regulations, the Company will provide evidence satisfactory to you
   that the Prospectus and term sheet meeting the requirements of Rule 434(b) or
   (c), as applicable, of the Rules and Regulations, have been filed, within the
   time period prescribed, with the Commission pursuant to subparagraph (7) of
   Rule 424(b) of the Rules and Regulations.  If for any reason the filing of
   the final form of Prospectus is required under Rule 424(b)(3) of the Rules
   and Regulations, it will provide evidence satisfactory to you that the
   Prospectus contains such information and has been filed with the Commission
   within the time period prescribed.  The Company will notify you promptly of
   any request by the Commission for the amending or supplementing of the
   Registration Statement or the Prospectus or for additional information.
   Promptly upon your request, the Company will prepare and file with the
   Commission any amendments or supplements to the Registration Statement or
   Prospectus that, in the opinion of Underwriters' Counsel, may be necessary or
   advisable in connection with the distribution of the Shares by the
   Underwriters.  The Company will promptly prepare and file with the
   Commission, and promptly notify you of the filing of, any amendments or
   supplements to the Registration Statement or Prospectus that may be necessary
   to correct any statements or omissions, if, at any time when a prospectus
   relating to the Shares is required to be delivered under the Act, any event
   shall have occurred as a result of which the Prospectus or any other
   prospectus relating to the Shares as then in effect would include any untrue
   statement of a material fact or omit to state a material fact necessary to
   make the statements therein, in the light of the circumstances under which
   they were made, not misleading.  In case any Underwriter is required to
   deliver a prospectus nine months or more after the effective date of the
   Registration Statement in connection with the sale of the Shares, it will
   prepare promptly upon request, but at the expense of such Underwriter, such
   amendment or amendments to the Registration Statement and such prospectus or
   prospectuses as may be necessary to permit compliance with the requirements
   of Section 10(a)(3) of the Act.  The Company will file no amendment or
   supplement to the Registration Statement or Prospectus that shall not
   previously have been submitted to you a reasonable time prior to the proposed
   filing thereof or to which you shall reasonably object in writing, subject,
   however, to compliance with the Act and the Rules and Regulations and the
   provisions of this Agreement.

       (b) The Company will advise you, promptly after it shall receive notice
   or obtain knowledge, of the issuance of any stop order by the Commission
   suspending the effectiveness of the Registration Statement or of the
   initiation or threat of any proceeding for that purpose.  The Company will
   promptly use its best efforts to prevent the issuance of any stop order or to
   obtain its withdrawal at the earliest possible moment if such stop order
   should be issued.

       (c) The Company will use its best efforts to qualify the Shares for
   offering and sale under the securities laws of such jurisdictions as you may
   designate and to continue such qualifications in effect for so long as may be
   required for purposes of the distribution of the Shares, except that the
   Company 

                                       14
<PAGE>
 
   shall not be required in connection therewith or as a condition thereof (i)
   to qualify as a foreign corporation, (ii) to execute a general consent to
   service of process in any jurisdiction in which it is not otherwise required
   to be so qualified or (iii) to so execute a general consent to service of
   process. In each jurisdiction in which the Shares shall have been qualified
   as above provided, the Company will make and file such statements and reports
   in each year as are or may be required by the laws of such jurisdiction.

       (d) The Company will furnish to you, as soon as available, and, in the
   case of the Prospectus and any term sheet or abbreviated term sheet under
   Rule 434, in no event later than the first full business day following the
   first day that Shares are traded, copies of the Registration Statement (three
   of which will be signed and which will include all exhibits), each
   Preliminary Prospectus, the Prospectus and any amendments or supplements to
   such documents, including any prospectus prepared to permit compliance with
   Section 10(a)(3) of the Act, all in such quantities as you may from time to
   time reasonably request.  Notwithstanding the foregoing, if BancBoston
   Robertson Stephens Inc., on behalf of the several Underwriters, shall agree
   to the utilization of Rule 434 of the Rules and Regulations, the Company
   shall provide to you copies of a Preliminary Prospectus updated in all
   respects through the date specified by you in such quantities as you may from
   time to time reasonably request.

       (e) The Company will make generally available to its securityholders as
   soon as practicable, but in any event not later than the forty-fifth day
   following the end of the fiscal quarter first occurring after the first
   anniversary of the effective date of the Registration Statement, an earnings
   statement (which will be in reasonable detail but need not be audited)
   complying with the provisions of Section 11(a) of the Act and covering a
   twelve-month period beginning after the effective date of the Registration
   Statement.

       (f) During a period of five years after the date hereof, the Company will
   furnish to its stockholders as soon as practicable after the end of each
   respective period, annual reports (including financial statements audited by
   independent certified public accountants) and unaudited quarterly reports of
   operations for each of the first three quarters of the fiscal year, and will
   furnish to you and the other several Underwriters hereunder, upon written
   request (i) concurrently with furnishing such reports to its stockholders,
   statements of operations of the Company for each of the first three quarters
   in the form furnished to the Company's stockholders, (ii) concurrently with
   furnishing to its stockholders, a balance sheet of the Company as of the end
   of such fiscal year, together with statements of operations, of stockholders'
   equity, and of cash flows of the Company for such fiscal year, accompanied by
   a copy of the certificate or report thereon of independent certified public
   accountants, (iii) as soon as they are available, copies of all reports
   (financial or other) mailed to stockholders, (iv) as soon as they are
   available, copies of all reports and financial statements furnished to or
   filed with the Commission, any securities exchange or the National
   Association of Securities Dealers, Inc. (the "NASD"), (v) every material
   press release and every material news item or article in respect of the
   Company or its affairs that was generally released to stockholders or
   prepared by the Company or either of its subsidiaries, and (vi) any
   additional information of a public nature concerning the Company or its
   subsidiaries, or its business that you may reasonably request.  During such
   five-year period, if the Company shall have any active subsidiaries, the
   foregoing financial statements shall be on a consolidated basis to the extent
   that the accounts of the Company and such subsidiaries are consolidated and
   shall be accompanied by similar financial statements for any significant
   subsidiary that is not so consolidated.

                                       15

   being sold by it in the manner set forth under the caption "Use of Proceeds"
   in the Prospectus.

       (h) The Company will maintain a transfer agent and, if necessary under
   the jurisdiction of incorporation of the Company, a registrar (which may be
   the same entity as the transfer agent) for the Common Stock.

       (i) If the transactions contemplated hereby are not consummated by reason
   of any failure, refusal or inability on the part of the Company or any
   Selling Stockholder to perform any agreement on their respective parts to be
   performed hereunder or to fulfill any condition of the Underwriters'
   obligations hereunder, or if the Company shall terminate this Agreement
   pursuant to Section 11(a), or if the Underwriters shall terminate this
   Agreement pursuant to Section 11(b)(i), the Company will reimburse the
   several Underwriters for all out-of-pocket expenses (including fees and
   disbursements of Underwriters' Counsel) reasonably incurred by the
   Underwriters in investigating or preparing to market or marketing the Shares.

       (j) If at any time during the ninety-day period after the Registration
   Statement becomes effective, any rumor, publication or event relating to or
   affecting the Company shall occur as a result of which in your reasonable
   judgment the market price of the Common Stock has been or is likely to be
   materially affected (regardless of whether such rumor, publication or event
   necessitates a supplement to or amendment of the Prospectus), the Company
   will, after written notice from you advising the Company to the effect set
   forth above, forthwith prepare, consult with you concerning the substance of
   and disseminate a press release or other public statement, reasonably
   satisfactory to you, responding to or commenting on such rumor, publication
   or event.

       (k) During the Lock-Up Period, the Company will not, without the prior
   written consent of BancBoston Robertson Stephens Inc., effect the Disposition
   of, directly or indirectly, any Securities other than the sale of the Shares
   to be sold by the Company hereunder and the Company's issuance of options or
   Common Stock under the Company's Long-Term Incentive Compensation Plan and
   1988 Stock Option Plan, each as presently authorized.

       (l) During a period of ninety days from the effective date of the
   Registration Statement, the Company will not file a registration statement
   registering shares under the Company's Long-Term Incentive Compensation Plan
   or 1988 Stock Option Plan or any other benefit plan.

   5.  Expenses.
       -------- 

       (a) The Company and the Selling Stockholders agree with each Underwriter
   that:

           (i) The Company will pay and bear all costs and expenses in
       connection with:  (A) the preparation, printing and filing of the
       Registration Statement (including financial statements, schedules and
       exhibits), Preliminary Prospectuses and the Prospectus and any amendments
       or supplements thereto; (B) the issuance and delivery of the Shares
       hereunder to the several Underwriters, including transfer taxes, if any,
       the cost of all certificates representing the Shares, and transfer
       agents' and registrars' fees; (C) the fees and disbursements of counsel
       for the Company; (D) all fees and other charges of the Company's
       independent certified public accountants; (E) the cost of furnishing to
       the several Underwriters copies of the Registration Statement (including
       appropriate exhibits), Preliminary Prospectuses and the Prospectus and
       any amendments or supplements to any of the foregoing; (F) NASD filing
       fees and the cost of 

                                       16
<PAGE>
 
       qualifying the Shares under the laws of such jurisdictions as you may
       designate (including filing fees and fees and disbursements of
       Underwriters' Counsel in connection with such NASD filings and Blue Sky
       qualifications, which fees of Underwriters' Counsel shall not exceed
       $10,000); and (G) all other expenses directly incurred by the Company and
       the Selling Stockholders in connection with the performance of their
       obligations hereunder. Any additional expenses incurred as a result of
       the sale of the Shares by the Selling Stockholders will be borne
       collectively by the Company and the Selling Stockholders. The provisions
       of this Section 5(a)(i) are intended to relieve the Underwriters from the
       payment of the expenses and costs that the Company and the Selling
       Stockholders hereby agree to pay, but shall not affect any agreement that
       the Company and the Selling Stockholders may make, or may have made, for
       the sharing of any of such expenses and costs. Such agreements shall not
       impair the obligations of the Company and the Selling Stockholders
       hereunder to the several Underwriters.

            (ii)   In addition to its other obligations under Section 8(a), the
       Company agrees that, as an interim measure during the pendency of any
       claim, action, investigation, inquiry or other proceeding described in
       Section 8(a), it will reimburse the Underwriters on a monthly basis for
       all reasonable legal or other expenses incurred in connection with
       investigating or defending any such claim, action, investigation, inquiry
       or other proceeding, notwithstanding the absence of a judicial
       determination as to the propriety and enforceability of the Company's
       obligation to reimburse the Underwriters for such expenses and the
       possibility that such payments might later be held to have been improper
       by a court of competent jurisdiction.  To the extent that any such
       interim reimbursement payment is so held to have been improper, the
       Underwriters shall promptly return such payment to the Company together
       with interest, compounded daily, determined on the basis of the prime
       rate (or other commercial lending rate for borrowers of the highest
       credit standing) listed from time to time in The Wall Street Journal that
       represents the base rate on corporate loans posted by a substantial
       majority of the nation's thirty largest banks (the "Prime Rate").  Any
       such interim reimbursement payments that are not made to the Underwriters
       within thirty days of a request for reimbursement shall bear interest at
       the Prime Rate from the date of such request.

            (iii)  In addition to the other obligations under Section 8(b), each
       Selling Stockholder agrees that, as an interim measure during the
       pendency of any claim, action, investigation, inquiry or other proceeding
       described in Section 8(b) relating to such Selling Stockholder, it will
       reimburse the Underwriters on a monthly basis for all reasonable legal or
       other expenses incurred in connection with investigating or defending any
       such claim, action, investigation, inquiry or other proceeding,
       notwithstanding the absence of a judicial determination as to the
       propriety and enforceability of such Selling Stockholder's obligation to
       reimburse the Underwriters for such expenses and the possibility that
       such payments might later be held to have been improper by a court of
       competent jurisdiction.  To the extent that any such interim
       reimbursement payment is so held to have been improper, the Underwriters
       shall promptly return such payment to the Selling Stockholders, together
       with interest, compounded daily, determined on the basis of the Prime
       Rate.  Any such interim reimbursement payments that are not made to the
       Underwriters within thirty days of a request for reimbursement shall bear
       interest at the Prime Rate from the date of such request.

       (b)  In addition to their other obligations under Section 8(c), the
   Underwriters severally and not jointly agree that, as an interim measure
   during the pendency of any claim, action, investigation, inquiry or other
   proceeding described in Section 8(c), they will reimburse the Company and
   each Selling Stockholder on a monthly basis for all reasonable legal or other
   expenses incurred in 

                                       17
<PAGE>
 
   connection with investigating or defending any such claim, action,
   investigation, inquiry or other proceeding, notwithstanding the absence of a
   judicial determination as to the propriety and enforceability of the
   Underwriters' obligation to reimburse the Company and each such Selling
   Stockholder for such expenses and the possibility that such payments might
   later be held to have been improper by a court of competent jurisdiction. To
   the extent that any such interim reimbursement payment is so held to have
   been improper, the Company and each such Selling Stockholder shall promptly
   return such payment to the Underwriters together with interest, compounded
   daily, determined on the basis of the Prime Rate. Any such interim
   reimbursement payments that are not made to the Company and each such Selling
   Stockholder within thirty days of a request for reimbursement shall bear
   interest at the Prime Rate from the date of such request.

       (c) It is agreed that any controversy arising out of the operation of the
   interim reimbursement arrangements set forth in Sections 5(a)(ii), 5(a)(iii)
   and 5(b), including the amounts of any requested reimbursement payments, the
   method of determining such amounts and the basis on which such amounts shall
   be apportioned among the reimbursing parties, shall be settled by arbitration
   conducted under the provisions of the Constitution and Rules of the Board of
   Governors of the New York Stock Exchange, Inc. or pursuant to the Code of
   Arbitration Procedure of the NASD.  Any such arbitration must be commenced by
   service of a written demand for arbitration or a written notice of intention
   to arbitrate, therein electing the arbitration tribunal.  In the event the
   party demanding arbitration does not make such designation of an arbitration
   tribunal in such demand or notice, then the party responding to said demand
   or notice is authorized to do so.  Any such arbitration will be limited to
   the operation of the interim reimbursement provisions contained in Sections
   5(a)(ii), 5(a)(iii) and 5(b) and will not resolve the ultimate propriety or
   enforceability of the obligation to indemnify for expenses that is created by
   the provisions of Sections 8(a), 8(b) and 8(c) or the obligation to
   contribute to expenses that is created by the provisions of Section 8(e).

   6.  Conditions of Underwriters' Obligations.  The obligations of the several
       ---------------------------------------                                 
Underwriters to purchase and pay for the Shares as provided herein shall be
subject to the accuracy, as of the date hereof and the Closing Date and any
later date on which Option Shares are to be purchased, as the case may be, of
the representations and warranties of the Company and the Selling Stockholders
herein, to the performance by the Company and the Selling Stockholders of their
respective obligations hereunder and to the following additional conditions:

       (a) The Registration Statement shall have become effective not later than
   2 P.M., San Francisco time, on the date following the date of this Agreement,
   or such later date as shall be consented to in writing by you.  No stop order
   suspending the effectiveness thereof shall have been issued and no
   proceedings for that purpose shall have been initiated or, to the knowledge
   of the Company, any Selling Stockholder or any Underwriter, threatened by the
   Commission.  Any request of the Commission for additional information (to be
   included in the Registration Statement or the Prospectus or otherwise) shall
   have been complied with to the reasonable satisfaction of Underwriters'
   Counsel.

       (b) All corporate proceedings and other legal matters in connection with
   this Agreement, the form of Registration Statement and the Prospectus, and
   the registration, authorization, issue, sale and delivery of the Shares,
   shall have been reasonably satisfactory to Underwriters' Counsel, and
   Underwriters' Counsel shall have been furnished with such papers and
   information as they may reasonably have requested to enable them to pass upon
   the matters referred to in this Section 6.

                                       18

       (c) Subsequent to the execution and delivery of this Agreement and prior
   to the Closing Date, or any later date on which Option Shares are to be
   purchased, as the case may be, there shall not have been any change in the
   condition (financial or otherwise), earnings, operations, business or
   business prospects of the Company and its subsidiaries considered as one
   enterprise from that set forth in the Registration Statement or Prospectus
   that, in your sole judgment, is material and adverse and that makes it, in
   your sole judgment, impracticable or inadvisable to proceed with the public
   offering of the Shares as contemplated by the Prospectus.

      (d) You shall have received on the Closing Date and on any later date on
   which Option Shares are to be purchased, as the case may be, the following
   opinion of Worsham, Forsythe & Wooldridge, L.L.P., counsel for the Company
   and the Selling Stockholders, dated the Closing Date or such later date on
   which Option Shares are to be purchased, addressed to the Underwriters and
   with reproduced copies or signed counterparts thereof for each of the
   Underwriters, to the effect that:

          (i)      The Company has been duly incorporated and is validly
      existing as a corporation in good standing under the laws of the State of
      Delaware.

          (ii)     The Company has the corporate power and authority to own,
      lease and operate its properties and to conduct its business as described
      in the Prospectus.

          (iii)    The Company is duly qualified to do business as a foreign
      corporation and is in good standing in each jurisdiction, if any, in which
      the ownership or leasing of its properties or the conduct of its business
      requires such qualification, except where the failure to be so qualified
      or be in good standing would not have a material adverse effect on the
      condition (financial or otherwise), earnings, operations or business of
      the Company and its subsidiaries considered as one enterprise.  To such
      counsel's knowledge, the Company does not own or control, directly or
      indirectly, any corporation, association or other entity other than
      Specialized Network Services, Inc. and SNS Credit Corporation.

          (iv)     The authorized, issued and outstanding capital stock of the
      Company is as set forth in the Prospectus under the caption
      "Capitalization" as of the dates stated therein.  The issued and
      outstanding shares of capital stock of the Company (including the Shares
      to be sold by the Selling Stockholders) have been duly and validly issued
      and are fully paid and nonassessable and, to such counsel's knowledge,
      have not been issued in violation of or subject to any preemptive right,
      co-sale right, registration right, right of first refusal or other similar
      right.

          (v)      The Firm Shares or the Option Shares, as the case may be, to
      be issued by the Company pursuant to the terms of this Agreement have been
      duly authorized and, upon issuance and delivery against payment therefor
      in accordance with the terms hereof, will be duly and validly issued and
      fully paid and nonassessable, and will not have been issued in violation
      of or subject to any preemptive right, co-sale right, registration right,
      right of first refusal or other similar right.

          (vi)     The Company has the corporate power and authority to enter
      into this Agreement and to issue, sell and deliver to the Underwriters the
      Shares to be issued and sold by it hereunder.

          (vii)    This Agreement has been duly authorized by all necessary
      corporate action on the part of the Company and has been duly executed and
      delivered by the Company and, assuming due authorization, execution and
      delivery by you, is a valid and binding agreement of the 

                                       19
<PAGE>
 
      Company, enforceable in accordance with its terms, except insofar as
      indemnification provisions may be limited by applicable law and except as
      enforceability may be limited by bankruptcy, insolvency, reorganization,
      moratorium or laws relating to or affecting creditors' rights generally or
      by general equitable principles.

          (viii)  The Registration Statement has become effective under the Act,
      and to such counsel's knowledge, no stop order suspending the
      effectiveness of the Registration Statement has been issued and no
      proceedings for that purpose have been instituted or are pending or
      threatened under the Act.

          (ix)    The Registration Statement and the Prospectus, and each
      amendment or supplement thereto (other than the financial statements,
      including supporting schedules, and financial data derived therefrom, as
      to which such counsel need express no opinion), as of the effective date
      of the Registration Statement, complied as to form in all material
      respects with the requirements of the Act and the applicable Rules and
      Regulations.

          (x)     The information in the Prospectus under the caption
      "Description of Capital Stock," to the extent that it constitutes matters
      of law or legal conclusions, has been reviewed by such counsel and is a
      fair summary of such matters and conclusions. The form of certificates
      representing the Common Stock and filed as an exhibit to the Registration
      Statement comply with the General Corporation Law of the State of
      Delaware.

          (xi)     The description in the Registration Statement and the
      Prospectus of the certificate of incorporation and bylaws of the Company
      and of statutes are accurate and fairly present in all material respects
      the information required to be presented by the Act and the applicable
      Rules and Regulations.

          (xii)    To such counsel's knowledge, there are no agreements,
      contracts, leases or documents to which the Company is a party of a
      character required to be described or referred to in the Registration
      Statement or Prospectus or to be filed as an exhibit to the Registration
      Statement that are not described or referred to therein or filed as
      required.

          (xiii)   The performance of this Agreement and the consummation of the
      transactions herein contemplated (other than performance of the Company's
      indemnification obligations hereunder, concerning which no opinion need be
      expressed) will not (a) result in any violation of the Company's
      certificate of incorporation or bylaws or (b) to such counsel's knowledge,
      result in a material breach or violation of any of the terms and
      provisions of, or constitute a default under, (1) any bond, debenture,
      note or other evidence of indebtedness, or any lease, contract, indenture,
      mortgage, deed of trust, loan agreement, joint venture or other agreement
      or instrument known to such counsel to which the Company is a party or by
      which its properties are bound, (2) any applicable statute, rule or
      regulation known to such counsel or (3) any order, writ or decree known to
      such counsel of any court, government or governmental agency or body
      having jurisdiction over the Company or either of its subsidiaries, or
      over any of their properties or operations.

          (xiv)    No consent, approval, authorization or order of or
      qualification with any court, government or governmental agency or body
      having jurisdiction over the Company or either of its subsidiaries, or
      over any of their properties or operations is necessary in connection with
      the consummation by the Company of the transactions herein contemplated,
      except such as have been 

                                       20
<PAGE>
 
      obtained under the Act or such as may be required under state or other
      securities or Blue Sky laws in connection with the purchase and the
      distribution of the Shares by the Underwriters.

          (xv)    To such counsel's knowledge, there are no legal or
      governmental proceedings pending or threatened against the Company or
      either of its subsidiaries of a character required to be disclosed in the
      Registration Statement or the Prospectus by the Act or the Rules and
      Regulations, other than those described therein.

          (xvi)   To such counsel's knowledge, the Company is not presently (a)
      in material violation of its certificate of incorporation or bylaws or (b)
      in material breach of any applicable statute, rule or regulation known to
      such counsel or, to such counsel's knowledge, any order, writ or decree of
      any court or governmental agency or body having jurisdiction over the
      Company or either of its subsidiaries, or over any of their properties or
      operations.

          (xvii)  To such counsel's knowledge, except as set forth in the
      Registration Statement and Prospectus, no holders of Common Stock or other
      securities of the Company have registration rights with respect to
      securities of the Company and, except as set forth in the Registration
      Statement and Prospectus, all holders of securities of the Company having
      rights known to such counsel to registration of such shares of Common
      Stock or other securities, because of the filing of the Registration
      Statement by the Company have, with respect to the offering contemplated
      thereby, waived such rights or such rights have expired by reason of lapse
      of time following notification of the Company's intent to file the
      Registration Statement or have included securities in the Registration
      Statement pursuant to the exercise of and in full satisfaction of such
      rights.

          (xviii) Each Selling Stockholder that is not a natural person has
      full right, power and authority to enter into and to perform its
      obligations under the Power of Attorney and Custody Agreement to be
      executed and delivered by it in connection with the transactions
      contemplated herein.  The Power of Attorney and Custody Agreement of each
      Selling Stockholder that is not a natural person has been duly authorized
      by such Selling Stockholder.  The Power of Attorney and Custody Agreement
      of each Selling Stockholder has been duly executed and delivered by or on
      behalf of such Selling Stockholder.  The Power of Attorney and Custody
      Agreement of each Selling Stockholder constitutes the valid and binding
      agreement of such Selling Stockholder, enforceable in accordance with its
      terms, except as the enforcement thereof may be limited by bankruptcy,
      insolvency, reorganization, moratorium or other similar laws relating to
      or affecting creditors' rights generally or by general equitable
      principles.

          (xix)   Each of the Selling Stockholders has full right (and, if such
      Selling Stockholder is not a natural person, full power and authority) to
      enter into and to perform its obligations under this Agreement and to
      sell, transfer, assign and deliver the Shares to be sold by such Selling
      Stockholder hereunder.

          (xx)    This Agreement has been duly authorized by each Selling
      Stockholder that is not a natural person and has been duly executed and
      delivered by or on behalf of each Selling Stockholder.

          (xxi)   Upon the delivery of and payment for the Shares as
      contemplated in this Agreement, each of the Underwriters will receive
      valid marketable title to the Shares purchased by it from such Selling
      Stockholder, free and clear of any pledge, lien, security interest,
      encumbrance, claim or equitable interest. In rendering such opinion, such
      counsel may assume that the Underwriters 

                                       21
<PAGE>
 
      are without notice of any defect in the title of the Shares being
      purchased from the Selling Stockholders.

          In addition, such counsel shall state that such counsel has
   participated in conferences with officials and other representatives of the
   Company, the Representatives, Underwriters' Counsel and the independent
   certified public accountants of the Company, at which such conferences the
   contents of the Registration Statement and Prospectus and related matters
   were discussed, and although they have not verified the accuracy or
   completeness of the statements contained in the Registration Statement or the
   Prospectus, nothing has come to the attention of such counsel that leads them
   to believe that, at the time the Registration Statement became effective and
   at all times subsequent thereto up to and on the Closing Date and on any
   later date on which Option Shares are to be purchased, the Registration
   Statement and any amendment or supplement thereto (other than the financial
   statements, including supporting schedules, and other financial and
   statistical information derived therefrom, as to which such counsel need
   express no comment) contained any untrue statement of a material fact or
   omitted to state a material fact required to be stated therein or necessary
   to make the statements therein not misleading, or at the Closing Date or any
   later date on which Option Shares are to be purchased, as the case may be,
   the Registration Statement, the Prospectus and any amendment or supplement
   thereto (except as aforesaid) contained any untrue statement of a material
   fact or omitted to state a material fact necessary to make the statements
   therein, in the light of the circumstances under which they were made, not
   misleading.

          Counsel rendering the foregoing opinion may rely as to questions of
   law not involving the laws of the United States, the State of Texas or the
   General Corporation Law of the State of Delaware upon opinions of local
   counsel, and as to questions of fact upon representations or certificates of
   officers of the Company, the Selling Stockholders, and government officials,
   in which case their opinion is to state that they are so relying and that
   they have no knowledge of any material misstatement or inaccuracy in any such
   opinion, representation or certificate.  Copies of any opinion,
   representation or certificate so relied upon shall be delivered to you, as
   Representatives of the Underwriters, and to Underwriters' Counsel.

      (e) You shall have received on the Closing Date and on any later date on
   which Option Shares are to be purchased, as the case may be, an opinion of
   Underwriters' Counsel, in form and substance satisfactory to you, with
   respect to the sufficiency of all such corporate proceedings and other legal
   matters relating to this Agreement and the transactions contemplated hereby
   as you may reasonably require, and the Company shall have furnished to
   Underwriters' Counsel such documents as they may have requested for the
   purpose of enabling them to pass upon such matters.

      (f) You shall have received on the Closing Date and on any later date on
   which Option Shares are to be purchased, as the case may be, a letter from
   Ernst & Young LLP addressed to the Underwriters, dated the Closing Date or
   such later date on which Option Shares are to be purchased, as the case may
   be, confirming that they are independent certified public accountants with
   respect to the Company within the meaning of the Act and the applicable
   published Rules and Regulations and based upon the procedures described in
   such letter delivered to you concurrently with the execution of this
   Agreement (herein called the "Original Letter"), but carried out to a date
   not more than five business days prior to the Closing Date or such later date
   on which Option Shares are to be purchased, as the case may be, (i)
   confirming, to the extent true, that the statements and conclusions set forth
   in the Original Letter are accurate as of the Closing Date or such later date
   on which Option Shares are to be purchased, as the case may be, and (ii)
   setting forth any revisions and additions to the statements and conclusions
   set forth in the Original Letter that are necessary to reflect any changes in
   the facts 

                                       22
<PAGE>
 
   described in the Original Letter since the date of such letter, or to reflect
   the availability of more recent financial statements, data or information.
   The letter shall not disclose any change in the condition (financial or
   otherwise), earnings, operations, business or business prospects of the
   Company and its subsidiaries considered as one enterprise from that set forth
   in the Registration Statement or Prospectus that, in your sole judgment, is
   material and adverse and that makes it, in your sole judgment, impracticable
   or inadvisable to proceed with the public offering of the Shares as
   contemplated by the Prospectus. The Original Letter from Ernst & Young LLP
   shall be addressed to or for the use of the Underwriters in form and
   substance satisfactory to the Underwriters and shall (i) represent that they
   are independent certified public accountants with respect to the Company
   within the meaning of the Act and the applicable published Rules and
   Regulations, (ii) set forth their opinion with respect to their examination
   of the consolidated balance sheets of the Company as of March 31, 1997 and
   1998 and related consolidated statements of operations, stockholders' equity,
   and cash flows for each of the years in the three year period ended March 31,
   1998, and (iii) address other matters agreed upon by Ernst & Young LLP and
   you. In addition, you shall have received from Ernst & Young LLP a letter
   addressed to the Company and made available to you for the use of the
   Underwriters stating that their review of the Company's system of internal
   accounting controls, to the extent they deemed necessary in establishing the
   scope of their examination of the Company's consolidated financial statements
   as of March 31, 1998, did not disclose any weaknesses in internal controls
   that they considered to be material weaknesses.

      (g) You shall have received on the Closing Date and on any later date on
   which Option Shares are to be purchased, as the case may be, a certificate of
   the Company, dated the Closing Date or such later date on which Option Shares
   are to be purchased, as the case may be, signed by the Chief Executive
   Officer and Chief Financial Officer of the Company, to the effect that, and
   you shall be satisfied that:

          (i)    The representations and warranties of the Company in this
      Agreement are true and correct, as if made on and as of the Closing Date
      or any later date on which Option Shares are to be purchased, as the case
      may be, and the Company has complied with all the agreements and satisfied
      all the conditions on its part to be performed or satisfied at or prior to
      the Closing Date or any later date on which Option Shares are to be
      purchased, as the case may be.

          (ii)   No stop order suspending the effectiveness of the Registration
      Statement has been issued and no proceedings for that purpose have been
      instituted or are pending or threatened under the Act.

          (iii)  When the Registration Statement became effective and at all
      times subsequent thereto up to the delivery of such certificate:  (a) the
      Registration Statement and the Prospectus, and any amendments or
      supplements thereto, contained all material information required to be
      included therein by the Act and the Rules and Regulations and in all
      material respects conformed to the requirements of the Act and the Rules
      and Regulations; (b) the Registration Statement, and any amendment or
      supplement thereto, did not and does not include any untrue statement of a
      material fact or omit to state a material fact required to be stated
      therein or necessary to make the statements therein not misleading; and
      (c) the Prospectus, and any amendment or supplement thereto, did not and
      does not include any untrue statement of a material fact or omit to state
      a material fact necessary to make the statements therein, in the light of
      the circumstances under which they were made, not misleading.  Since the
      effective date of the Registration Statement, there has occurred no event
      required to be set forth in an amended or supplemented Prospectus that has
      not been so set forth.

                                       23
<PAGE>
 
          (iv)   Subsequent to the respective dates as of which information is
      given in the Registration Statement and Prospectus, there has not been:
      (a) any material adverse change in the condition (financial or otherwise),
      earnings, operations, business or business prospects of the Company and
      its subsidiaries considered as one enterprise; (b) any transaction that is
      material to the Company and its subsidiaries considered as one enterprise,
      except transactions entered into in the ordinary course of business; (c)
      any obligation, direct or contingent, that is material to the Company and
      its subsidiaries considered as one enterprise, incurred by the Company or
      its subsidiaries, except obligations incurred in the ordinary course of
      business; (d) any change in the capital stock or outstanding indebtedness
      of the Company or either of its subsidiaries that is material to the
      Company and its subsidiaries considered as one enterprise; (e) any
      dividend or distribution of any kind declared, paid or made on the capital
      stock of the Company or either of its subsidiaries; or (f) any loss or
      damage (whether or not insured) to the property of the Company or either
      of its subsidiaries that has been sustained or will have been sustained
      and that has a material adverse effect on the condition (financial or
      otherwise), earnings, operations, business or business prospects of the
      Company and its subsidiaries considered as one enterprise.

      (h) You shall be satisfied that, and you shall have received a certificate
   from the Attorneys, dated the Closing Date or any later date on which Option
   Shares are to be purchased from a Selling Stockholder, to the effect that, as
   of the Closing Date or such later date, as the case may be, they have not
   been informed that:

          (i)    the representations and warranties made by such Selling
      Stockholder herein are not true or correct in any material respect on the
      Closing Date or on any later date on which Option Shares are to be
      purchased from such Selling Stockholder, as the case may be; or

          (ii)   such Selling Stockholder has not complied with any obligation
      or satisfied any condition that is required to be performed or satisfied
      on the part of such Selling Stockholder at or prior to the Closing Date or
      any later date on which Option Shares are to be purchased from such
      Selling Stockholder, as the case may be.

      (i) The Company shall have obtained and delivered to you an agreement from
   each officer and director of the Company, each Selling Stockholder and each
   other record holder of Common Stock in writing prior to the date hereof that
   such person will not, during the Lock-Up Period, effect the Disposition of
   any Securities now owned or hereafter acquired directly by such person or
   with respect to which such person has or hereafter acquires the power of
   disposition, otherwise than (i) as a bona fide gift or a distribution to
   limited partners, members or stockholders of such person, provided that the
   donees or distributees thereof (or as the case may be) agree in writing to be
   bound by the terms of this restriction or (ii) with the prior written consent
   of BancBoston Robertson Stephens Inc.  The foregoing restriction shall have
   been expressly agreed to preclude the holder of the Securities from engaging
   in any hedging or other transaction which is designed to or reasonably
   expected to lead to or result in a Disposition of Securities during the Lock-
   Up Period, even if such Securities would be disposed of by someone other than
   the such holder.  Such prohibited hedging or other transactions would include
   any short sale (whether or not against the box) or any purchase, sale or
   grant of any right (including any put or call option) with respect to any
   Securities or with respect to any security (other than a broad-based market
   basket or index) that includes, relates to or derives any significant part of
   its value from the Securities.  Notwithstanding the foregoing, this
   restriction shall not prohibit (i) the sale of Shares to the Underwriters
   pursuant to this Agreement or (ii) resales of shares of Common Stock acquired
   either in the public offering to which the Registration Statement relates or
   in subsequent open-market purchases.  Furthermore, such person will have also
   agreed and consented to the entry of stop 

                                       24
<PAGE>
 
   transfer instructions with the Company's transfer agent against the transfer
   of the Securities held by such person except in compliance with this
   restriction.

       (j) The Company and the Selling Stockholders shall have furnished to you
   such further certificates and documents as you shall reasonably request
   (including certificates of officers of the Company, the Selling Stockholders
   or officers of the Selling Stockholders (when the Selling Stockholder is not
   a natural person) as to the accuracy of the representations and warranties of
   the Company and the Selling Stockholders herein, as to the performance by the
   Company and the Selling Stockholders of their respective obligations
   hereunder and as to the other conditions concurrent and precedent to the
   obligations of the Underwriters hereunder.

       All such opinions, certificates, letters and documents will be in
compliance with the provisions hereof only if they are reasonably satisfactory
to Underwriters' Counsel.  The Company and the Selling Stockholders will furnish
you with such number of conformed copies of such opinions, certificates, letters
and documents as you shall reasonably request.

   7.  Option Shares.
       ------------- 

       (a) On the basis of the representations, warranties and agreements herein
   contained, but subject to the terms and conditions herein set forth, the
   Company and the Selling Stockholders hereby grant, severally and not jointly,
   to the several Underwriters, for the purpose of covering over-allotments in
   connection with the distribution and sale of the Firm Shares only,
   nontransferable options to purchase the respective number of Option Shares as
   set forth opposite the names of the Company and the Selling Stockholders in
   Schedule B hereto, all at the purchase price per share for the Firm Shares
   set forth in Section 3.  Such option may be exercised by the Representatives
   on behalf of the several Underwriters on one or more occasions in whole or in
   part during the period of thirty days after the date on which the Firm Shares
   are initially offered to the public, by giving written notice to the Company
   and the Selling Stockholders in accordance with Section 12.  The number of
   Option Shares to be purchased by each Underwriter upon the exercise of such
   option shall be the same proportion of the total number of Option Shares to
   be purchased by the several Underwriters pursuant to the exercise of such
   option as the number of Firm Shares purchased by such Underwriter (set forth
   in Schedule A hereto) bears to the total number of Firm Shares purchased by
   the several Underwriters (set forth in Schedule A hereto), adjusted by the
   Representatives in such manner as to avoid fractional shares.  In the event
   such option is exercised for less than all of the Option Shares, the Option
   Shares to be purchased shall be purchased pro rata (based on the numbers of
   Option Shares set forth in Schedule B hereto) from the Company and each of
   the Selling Stockholders named in Schedule B hereto, adjusted by the
   Representatives in such manner as to avoid fractional shares.

          The certificates in negotiable form for Option Shares to be purchased
   from the Selling Stockholders pursuant to the exercise of the option granted
   by this Section 7 have been placed in custody (for delivery under this
   Agreement) under the Custody Agreement.  Each Selling Stockholder agrees that
   the certificates for the Option Shares to be sold by such Selling Stockholder
   so held in custody are subject to the interests of the Underwriters
   hereunder, that the arrangements made by such Selling Stockholder for such
   custody, including the Power of Attorney is to that extent irrevocable and
   that the obligations of such Selling Stockholder hereunder shall not be
   terminated by the act of such Selling Stockholder or by operation of law,
   whether by the death or incapacity of such Selling Stockholder or the
   occurrence of any other event, except as specifically provided herein or in
   the Custody Agreement.  If any Selling Stockholder should die or be
   incapacitated, or if any other such event should occur, before the delivery
   of the certificates for the Option Shares to be sold by such 

                                       25
<PAGE>
 
   Selling Stockholder, such Option Shares shall, except as specifically
   provided herein or in the Custody Agreement, be delivered by the Custodian in
   accordance with the terms and conditions of this Agreement as if such death,
   incapacity or other event had not occurred, regardless of whether the
   Custodian shall have received notice of such death or other event.

      Delivery of definitive certificates for the Option Shares to be purchased
   by the several Underwriters pursuant to the exercise of the option granted by
   this Section 7 shall be made against payment of the purchase price therefor
   by the several Underwriters by certified or official bank check or checks
   drawn in same-day funds or by wire transfer of same-day funds, payable to the
   order of the Company with regard to the Option Shares being purchased from
   the Company, and to the order of the Custodian for the respective accounts of
   Option Stockholders with regard to the Option Shares being purchased from the
   Option Stockholders.  Such delivery and payment shall take place at the
   offices of Worsham, Forsythe & Wooldridge, L.L.P., 1601 Bryan Street, Suite
   3000, Dallas, Texas 75201 or at such other place as may be agreed upon among
   the Representatives, the Company and the Attorneys (i) on the Closing Date,
   if written notice of the exercise of such option is received by the Company
   and the Selling Stockholders at least two full business days prior to the
   Closing Date, or (ii) on a date that shall not be later than the third full
   business day following the date the Company and the Selling Stockholders
   receive written notice of the exercise of such option, if such notice is
   received by the Company and the Selling Stockholders less than two full
   business days prior to the Closing Date.

           The certificates for the Option Shares to be so delivered will be
   made available to you at such office or such other location, including in New
   York City, as you may reasonably request for checking at least one full
   business day prior to the date of payment and delivery and will be in such
   names and denominations as you may request, such request to be made at least
   two full business days prior to such date of payment and delivery. If the
   Representatives so elect, delivery of the Option Shares may be made by credit
   through full fast transfer to the accounts at The Depository Trust Company
   designated by the Representatives.

           It is understood that you, individually, and not as the
   Representatives of the several Underwriters, may (but shall not be obligated
   to) make payment of the purchase price on behalf of any Underwriter or
   Underwriters whose check or checks shall not have been received by you prior
   to the date of payment and delivery for the Option Shares to be purchased by
   such Underwriter or Underwriters.  Any such payment by you shall not relieve
   any such Underwriter or Underwriters of any of its or their obligations
   hereunder.

      (b)  Upon exercise of any option provided for in Section 7(a), the
   obligations of the several Underwriters to purchase such Option Shares will
   be subject (as of the date hereof and as of the date of payment and delivery
   for such Option Shares) to the accuracy of and compliance with the
   representations, warranties and agreements of the Company and the Selling
   Stockholders herein, to the accuracy of the statements of the Company, the
   Selling Stockholders and officers of the Company made pursuant to the
   provisions hereof, to the performance by the Company and the Selling
   Stockholders of their respective obligations hereunder, to the conditions set
   forth in Section 6, and to the condition that all proceedings taken at or
   prior to the payment date in connection with the sale and transfer of such
   Option Shares shall be satisfactory in form and substance to you and to
   Underwriters' Counsel, and you shall have been furnished with all such
   documents, certificates and opinions as you may request in order to evidence
   the accuracy and completeness of any of the representations, warranties or
   statements, the performance of any of the covenants or agreements of the
   Company and the Selling Stockholders or the satisfaction of any of the
   conditions herein contained.

   8.  Indemnification and Contribution.
       -------------------------------- 

       (a)  The Company agrees to indemnify and hold harmless each Underwriter
   against any losses, claims, damages or liabilities, joint or several, to
   which such Underwriter may become subject (including in its capacity as an
   Underwriter), under the Act, the Exchange Act or otherwise, specifically
   including losses, claims, damages or liabilities (or actions in respect
   thereof) arising out of or based upon (i) any breach of any representation,
   warranty, agreement or covenant of the Company herein contained, (ii) any
   untrue statement or alleged untrue statement of any material fact contained
   in the Registration Statement or any amendment or supplement thereto, or the
   omission or alleged omission to state therein a material fact required to be
   stated therein or necessary to make the statements therein not misleading or
   (iii) any untrue statement or alleged untrue statement of any material fact
   contained in any Preliminary Prospectus or the Prospectus or any amendment or
   supplement thereto, or the omission or alleged omission to state therein a
   material fact required to be stated therein or necessary to make the
   statements therein, in the light of the circumstances under which they were
   made, not misleading, and agrees to reimburse each Underwriter for any legal
   or other expenses reasonably incurred by it in connection with investigating
   or defending any such loss, claim, damage, liability or action; provided,
   however, that the Company shall not be liable in any such case to the extent
   that any such loss, claim, damage, liability or action arises out of or is
   based upon an untrue statement or alleged untrue statement or omission or
   alleged omission made in the Registration Statement, such Preliminary
   Prospectus or the Prospectus, or any such amendment or supplement thereto, in
   reliance upon, and in conformity with, written information relating to any
   Underwriter furnished to the Company by such Underwriter, directly or through
   you, specifically for use in the preparation thereof and, provided further
   that the indemnity agreement provided in this Section 8(a) with respect to
   any Preliminary Prospectus shall not inure to the benefit of any Underwriter
   from whom the person asserting any losses, claims, damages, liabilities or
   actions based upon any untrue statement or alleged untrue statement of
   material fact or omission or alleged omission to state therein a material
   fact purchased Shares, if a copy of the Prospectus in which such untrue
   statement or alleged untrue statement or omission or alleged omission was
   corrected had not been sent or given to such person within the time required
   by the Act and the Rules and Regulations, unless such failure is the result
   of noncompliance by the Company with Section 4(d).

            The indemnity agreement in this Section 8(a) shall extend upon the
   same terms and conditions to, and shall inure to the benefit of, each person,
   if any, who controls any Underwriter within the meaning of the Act or the
   Exchange Act.  This indemnity agreement shall be in addition to any
   liabilities that the Company may otherwise have.

       (b)  Subject to Section 8(f), each Selling Stockholder, severally and not
   jointly, agrees to indemnify and hold harmless each Underwriter against any
   losses, claims, damages or liabilities, joint or several, to which such
   Underwriter may become subject (including in its capacity as an Underwriter)
   under the Act, the Exchange Act or otherwise, specifically including losses,
   claims, damages or liabilities (or actions in respect thereof) arising out of
   or based upon (i) any breach of any representation, warranty, agreement or
   covenant of such Selling Stockholder herein contained, (ii) any untrue
   statement or alleged untrue statement of any material fact contained in the
   Registration Statement or any amendment or supplement thereto, or the
   omission or alleged omission to state therein a material fact required to be
   stated therein or necessary to make the statements therein not misleading, or
   (iii) any untrue statement or alleged untrue statement of any material fact
   contained in any Preliminary Prospectus or the Prospectus or any amendment or
   supplement thereto, or the omission or alleged omission to state therein a
   material fact necessary to make the statements therein, in the light of the
   circumstances under which they were made, not misleading, in the case of
   subparagraphs (ii) and 

                                       27
<PAGE>
 
   (iii) of this Section 8(b) to the extent, but only to the extent, that such
   untrue statement or alleged untrue statement or omission or alleged omission
   was made in reliance upon and in conformity with written information
   furnished to the Company or such Underwriter by such Selling Stockholder,
   directly or through such Selling Stockholder's representatives, specifically
   for use in the preparation thereof, and agrees to reimburse each Underwriter
   for any legal or other expenses reasonably incurred by it in connection with
   investigating or defending any such loss, claim, damage, liability or action;
   provided, however, that the indemnity agreement provided in this Section 8(b)
   with respect to any Preliminary Prospectus shall not inure to the benefit of
   any Underwriter from whom the person asserting any losses, claims, damages,
   liabilities or actions based upon any untrue statement or alleged untrue
   statement of a material fact or omission or alleged omission to state therein
   a material fact purchased Shares, if a copy of the Prospectus in which such
   untrue statement or alleged untrue statement or omission or alleged omission
   was corrected had not been sent or given to such person within the time
   required by the Act and the Rules and Regulations, unless such failure is the
   result of noncompliance by the Company with Section 4(d).

           The indemnity agreement in this Section 8(b) shall extend upon the
   same terms and conditions to, and shall inure to the benefit of, each person,
   if any, who controls any Underwriter within the meaning of the Act or the
   Exchange Act.  This indemnity agreement shall be in addition to any
   liabilities that such Selling Stockholder otherwise may have.

      (c)  Each Underwriter, severally and not jointly, agrees to indemnify and
   hold harmless the Company and each Selling Stockholder against any losses,
   claims, damages or liabilities, joint or several, to which the Company or
   such Selling Stockholder may become subject under the Act or otherwise,
   specifically including losses, claims, damages or liabilities (or actions in
   respect thereof) arising out of or based upon (i) any breach of any
   representation, warranty, agreement or covenant of such Underwriter herein
   contained, (ii) any untrue statement or alleged untrue statement of any
   material fact contained in the Registration Statement or any amendment or
   supplement thereto, or the omission or alleged omission to state therein a
   material fact required to be stated therein or necessary to make the
   statements therein not misleading or (iii) any untrue statement or alleged
   untrue statement of any material fact contained in any Preliminary Prospectus
   or the Prospectus or any amendment or supplement thereto, or the omission or
   alleged omission to state therein a material fact necessary to make the
   statements therein, in the light of the circumstances under which they were
   made, not misleading, in the case of subparagraphs (ii) and (iii) of this
   Section 8(c) to the extent, but only to the extent, that such untrue
   statement or alleged untrue statement or omission or alleged omission was
   made in reliance upon and in conformity with written information furnished to
   the Company by such Underwriter, directly or through you, specifically for
   use in the preparation thereof, and agrees to reimburse the Company and each
   such Selling Stockholder for any legal or other expenses reasonably incurred
   by the Company and each such Selling Stockholder in connection with
   investigating or defending any such loss, claim, damage, liability or action.

           The indemnity agreement in this Section 8(c) shall extend upon the
   same terms and conditions to, and shall inure to the benefit of, each officer
   of the Company who signed the Registration Statement and each director of the
   Company, each Selling Stockholder and each person, if any, who controls the
   Company or any Selling Stockholder within the meaning of the Act or the
   Exchange Act.  This indemnity agreement shall be in addition to any
   liabilities that each Underwriter may otherwise have.

      (d)  Promptly after receipt by an indemnified party under this Section 8
   of notice of the commencement of any action, such indemnified party shall, if
   a claim in respect thereof is to be made 

                                       28
<PAGE>
 
   against any indemnifying party under this Section 8, notify the indemnifying
   party in writing of the commencement thereof but the omission so to notify
   the indemnifying party will not relieve it from any liability that it may
   have to any indemnified party otherwise than under this Section 8. In case
   any such action is brought against any indemnified party, and it notified the
   indemnifying party of the commencement thereof, the indemnifying party will
   be entitled to participate therein and, to the extent that it shall elect by
   written notice delivered to the indemnified party promptly after receiving
   the aforesaid notice from such indemnified party, to assume the defense
   thereof, with counsel reasonably satisfactory to such indemnified party;
   provided, however, that if the defendants in any such action include both the
   indemnified party and the indemnifying party and the indemnified party shall
   have reasonably concluded that there may be legal defenses available to it
   and/or other indemnified parties that are different from or additional to
   those available to the indemnifying party, the indemnified party or parties
   shall have the right to select separate counsel to assume such legal defenses
   and to otherwise participate in the defense of such action on behalf of such
   indemnified party or parties. Upon receipt of notice from the indemnifying
   party to such indemnified party of the indemnifying party's election so to
   assume the defense of such action and approval by the indemnified party of
   counsel, the indemnifying party will not be liable to such indemnified party
   under this Section 8 for any legal or other expenses subsequently incurred by
   such indemnified party in connection with the defense thereof unless (i) the
   indemnified party shall have employed separate counsel in accordance with the
   proviso to the next preceding sentence (it being understood, however, that
   the indemnifying party shall not be liable for the expenses of more than one
   separate counsel (together with appropriate local counsel) approved by the
   indemnifying party representing all the indemnified parties under Section
   8(a), 8(b) or 8(c) who are parties to such action), (ii) the indemnifying
   party shall not have employed counsel satisfactory to the indemnified party
   to represent the indemnified party within a reasonable time after notice of
   commencement of the action or (iii) the indemnifying party has authorized the
   employment of counsel for the indemnified party at the expense of the
   indemnifying party. In no event shall any indemnifying party be liable in
   respect of any amounts paid in settlement of any action unless the
   indemnifying party shall have approved the terms of such settlement; provided
   that such consent shall not be unreasonably withheld. No indemnifying party
   shall, without the prior written consent of the indemnified party, effect any
   settlement of any pending or threatened proceeding in respect of which any
   indemnified party is or could have been a party and indemnification could
   have been sought hereunder by such indemnified party, unless such settlement
   includes an unconditional release of such indemnified party from all
   liability on all claims that are the subject matter of such proceeding.

      (e)  In order to provide for just and equitable contribution in any action
   in which a claim for indemnification is made pursuant to this Section 8 but
   it is judicially determined (by the entry of a final judgment or decree by a
   court of competent jurisdiction and the expiration of time to appeal or the
   denial of the last right of appeal) that such indemnification may not be
   enforced in such case notwithstanding the fact that this Section 8 provides
   for indemnification in such case, all the parties hereto shall contribute to
   the aggregate losses, claims, damages or liabilities to which they may be
   subject (after contribution from others) in such proportion so that, except
   as set forth in Section 8(f), the Underwriters severally and not jointly are
   responsible pro rata for the portion represented by the percentage that the
   underwriting discount bears to the initial public offering price, and the
   Company and the Selling Stockholders are responsible for the remaining
   portion, provided, however, that (i) no Underwriter shall be required to
   contribute any amount in excess of the amount by which the underwriting
   discount applicable to the Shares purchased by such Underwriter exceeds the
   amount of damages that such Underwriter has otherwise required to pay and
   (ii) no person guilty of a fraudulent misrepresentation (within the meaning
   of Section 11(f) of the Act) shall be entitled to contribution from any
   person who is not guilty of such fraudulent misrepresentation.  The
   contribution agreement in this Section 8(e) shall extend upon the same terms
   and conditions to, and shall inure to the benefit of, each 

                                       29
<PAGE>
 
   person, if any, who controls any Underwriter, the Company or any Selling
   Stockholder within the meaning of the Act or the Exchange Act and each
   officer of the Company who signed the Registration Statement and each
   director of the Company.

        (f)  The liability of each Selling Stockholder under the
   representations, warranties and agreements contained herein and under the
   indemnity and contribution agreements contained in the provisions of this
   Section 8 shall be limited to an amount equal to the initial public offering
   price of any Shares sold by such Selling Stockholder to the Underwriters
   minus the amount of the underwriting discount paid thereon to the
   Underwriters by such Selling Stockholder. The Company and such Selling
   Stockholders may agree, as among themselves and without limiting the rights
   of the Underwriters under this Agreement, as to the respective amounts of
   such liability for which they each shall be responsible.

        (g)  The parties to this Agreement hereby acknowledge that they are
   sophisticated business persons who were represented by counsel during the
   negotiations regarding the provisions hereof including the provisions of this
   Section 8, and are fully informed regarding said provisions.  They further
   acknowledge that the provisions of this Section 8 fairly allocate the risks
   in light of the ability of the parties to investigate the Company and its
   business in order to assure that adequate disclosure is made in the
   Registration Statement and Prospectus as required by the Act and the Exchange
   Act.

   9.   Representations, Warranties, Covenants and Agreements to Survive
        ----------------------------------------------------------------
Delivery.  All representations, warranties, covenants and agreements of the
- --------
Company, the Selling Stockholders and the Underwriters herein or in certificates
delivered pursuant hereto, and the indemnity and contribution agreements
contained in Section 8 shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of any Underwriter or any
person controlling any Underwriter within the meaning of the Act or the Exchange
Act, or by or on behalf of the Company or any Selling Stockholder, or any of
their officers, directors or controlling persons within the meaning of the Act
or the Exchange Act, and shall survive the delivery of the Shares to the several
Underwriters hereunder or termination of this Agreement.

   10.  Substitution of Underwriters.  If any Underwriter or Underwriters shall
        ----------------------------                                           
fail to take up and pay for the number of Firm Shares agreed by such Underwriter
or Underwriters to be purchased hereunder upon tender of such Firm Shares in
accordance with the terms hereof, and if the aggregate number of Firm Shares
that such defaulting Underwriter or Underwriters so agreed but failed to
purchase does not exceed ten percent of the Firm Shares, the remaining
Underwriters shall be obligated, severally in proportion to their respective
commitments hereunder, to take up and pay for the Firm Shares of such defaulting
Underwriter or Underwriters.

        If any Underwriter or Underwriters so defaults and the aggregate number
of Firm Shares that such defaulting Underwriter or Underwriters agreed but
failed to take up and pay for exceeds ten percent of the Firm Shares, the
remaining Underwriters shall have the right, but shall not be obligated, to take
up and pay for (in such proportions as may be agreed upon among them) the Firm
Shares that the defaulting Underwriter or Underwriters so agreed but failed to
purchase. If such remaining Underwriters do not, at the Closing Date, take up
and pay for the Firm Shares that the defaulting Underwriter or Underwriters so
agreed but failed to purchase, the Closing Date shall be postponed for twenty-
four hours to allow the several Underwriters the privilege of substituting
within twenty-four hours (including non-business hours) another underwriter or
underwriters (which may include any nondefaulting Underwriter) satisfactory to
the Company. If no such underwriter or underwriters shall have been substituted
as aforesaid by such postponed Closing Date, the Closing Date may, at the option
of the Company, be postponed for a further twenty-four hours, if necessary, to
allow the Company the privilege of finding another underwriter or underwriters,
satisfactory to you, to purchase the Firm Shares that the defaulting Underwriter
or Underwriters so agreed but failed to purchase. 

                                       30
<PAGE>
 
If it shall be arranged for the remaining Underwriters or substituted
underwriter or underwriters to take up the Firm Shares of the defaulting
Underwriter or Underwriters as provided in this Section 10, (i) the Company
shall have the right to postpone the time of delivery for a period of not more
than seven full business days, in order to effect whatever changes may thereby
be made necessary in the Registration Statement or the Prospectus, or in any
other documents or arrangements, and the Company agrees promptly to file any
amendments to the Registration Statement, supplements to the Prospectus or other
such documents that may thereby be made necessary, and (ii) the respective
number of Firm Shares to be purchased by the remaining Underwriters and
substituted underwriter or underwriters shall be taken as the basis of their
underwriting obligation. If the remaining Underwriters shall not take up and pay
for all such Firm Shares so agreed to be purchased by the defaulting Underwriter
or Underwriters or substitute another underwriter or underwriters as aforesaid
and the Company shall not find or shall not elect to seek another underwriter or
underwriters for such Firm Shares as aforesaid, then this Agreement shall
terminate.

        In the event of any termination of this Agreement pursuant to the
preceding paragraph of this Section 10, neither the Company nor any Selling
Stockholder shall be liable to any Underwriter (except as provided in Sections 5
and 8) nor shall any Underwriter (other than an Underwriter who shall have
failed, otherwise than for some reason permitted under this Agreement, to
purchase the number of Firm Shares agreed by such Underwriter to be purchased
hereunder, which Underwriter shall remain liable to the Company, the Selling
Stockholders and the other Underwriters for damages, if any, resulting from such
default) be liable to the Company or any Selling Stockholder (except to the
extent provided in Sections 5 and 8).

        The term "Underwriter" in this Agreement shall include any person
substituted for an Underwriter under this Section 10.

   11.  Effective Date of this Agreement and Termination.
        ------------------------------------------------ 

        (a)  This Agreement shall become effective at the earlier of (i) 6:30
   A.M., San Francisco time, on the first full business day following the
   effective date of the Registration Statement or (ii) the time of the initial
   public offering of any of the Shares by the Underwriters after the
   Registration Statement becomes effective.  The time of the initial public
   offering shall mean the time of the release by you, for publication, of the
   first newspaper advertisement relating to the Shares, or the time at which
   the Shares are first generally offered by the Underwriters to the public by
   letter, telephone, telegram or telecopy, whichever shall first occur.  By
   giving notice as set forth in Section 12 before the time this Agreement
   becomes effective, you, as Representatives of the several Underwriters, or
   the Company, may prevent this Agreement from becoming effective without
   liability of any party to any other party, except as provided in Sections
   4(j), 5 and 8.

        (b)  You, as Representatives of the several Underwriters, shall have the
   right to terminate this Agreement by giving notice as hereinafter specified
   at any time on or prior to the Closing Date or on or prior to any later date
   on which Option Shares are to be purchased, as the case may be, (i) if the
   Company or any Selling Stockholder shall have failed, refused or been unable
   to perform any agreement on its part to be performed, or because any other
   condition of the Underwriters' obligations hereunder required to be fulfilled
   is not fulfilled, including any change in the condition (financial or
   otherwise), earnings, operations, business or business prospects of the
   Company and its subsidiaries considered as one enterprise from that set forth
   in the Registration Statement or Prospectus that, in your sole judgment, is
   material and adverse, or (ii) if additional material governmental
   restrictions, not in force and effect on the date hereof, shall have been
   imposed upon trading in securities generally or minimum or maximum prices
   shall have been generally established on the New York Stock Exchange or on
   the American Stock Exchange 

                                       31
<PAGE>
 
   or in the over-the-counter market by the NASD, or trading in securities
   generally shall have been suspended on either such exchange or in the over-
   the-counter market by the NASD, or if a banking moratorium shall have been
   declared by federal, New York or California authorities, or (iii) if the
   Company shall have sustained a loss by strike, fire, flood, earthquake,
   accident or other calamity of such character as to interfere materially with
   the conduct of the business and operations of the Company regardless of
   whether or not such loss shall have been insured or (iv) if there shall have
   been a material adverse change in the general political or economic
   conditions or financial markets as in your reasonable judgment makes it
   inadvisable or impracticable to proceed with the offering, sale and delivery
   of the Shares, or (v) if there shall have been an outbreak or escalation of
   hostilities or of any other insurrection or armed conflict or the declaration
   by the United States of a national emergency that, in the reasonable opinion
   of the Representatives, makes it impracticable or inadvisable to proceed with
   the public offering of the Shares as contemplated by the Prospectus. In the
   event of termination pursuant to subparagraph (i) above, the Company shall
   remain obligated to pay costs and expenses pursuant to Sections 4(j), 5 and
   8. Any termination pursuant to any of subparagraphs (ii) through (v) above
   shall be without liability of any party to any other party except as provided
   in Sections 5 and 8.

          If you elect to prevent this Agreement from becoming effective or to
   terminate this Agreement as provided in this Section 11, you shall promptly
   notify the Company by telephone, telecopy or telegram, in each case confirmed
   by letter.  If the Company shall elect to prevent this Agreement from
   becoming effective, the Company shall promptly notify you by telephone,
   telecopy or telegram, in each case, confirmed by letter.

                              COMPOSITE RESTATED
                         CERTIFICATE OF INCORPORATION
                                      OF
                            NETSOLVE, INCORPORATED
                           INCLUDING ALL AMENDMENTS
                      AS IN EFFECT ON SEPTEMBER 30, 1998


     NETSOLVE, INCORPORATED, a corporation organized and existing under the laws
of the State of Delaware, hereby certifies as follows:

          FIRST:  The name of the Corporation is NetSolve, Incorporated.

          SECOND:  The address of the registered office of the Corporation in
     the State of Delaware is 1209 Orange Street, Wilmington, County of New
     Castle, Delaware. The name of the registered agent at the Corporation of
     such address is The Corporation Trust Company.

          THIRD:  The purpose of the Corporation is to engage in any lawful act
     or actions for which corporations may be organized under the General
     Corporation Law of the State of Delaware.

          FOURTH:  (a) Authorized Shares and Classes of Stock.  The total number
     of shares of stock which the Corporation shall have authority to issue is
     Twenty-One Million Five Hundred Thousand (21,500,000), of which Fourteen
     Million (14,000,000) shares of the par value of One Cent ($.01) each,
     amounting in the aggregate to One Hundred Forty Thousand Dollars
     ($140,000.00), shall be Common Stock and of which Seven Million Five
     Hundred Thousand (7,500,000) shares of the par value of Ten Cents ($.10)
     each, amounting in the aggregate to Seven Hundred Fifty Thousand Dollars
     ($750,000.00) shall be Preferred Stock.

          (b)  Designation, Rights, Preferences and Powers of the Series A
     Preferred Stock.

          1.   Designation.  The first series of Preferred Stock shall be
     designated "Series A Preferred Stock."

          2.   Authorized Number.  The number of shares constituting the Series
     A Preferred Stock shall be 4,150,000 shares, which number may be increased
     or decreased from time to time (but not decreased below the number of
     shares then outstanding) by the Board of Directors pursuant to the
     provisions of Section (c) hereof.
<PAGE>
 
          3.   Dividend Provisions.  The holders of shares of Series A Preferred
     Stock shall be entitled to receive dividends, out of the assets legally
     available therefor, at the rate of $.40 per share per annum (the "Stated
     Dividend Rate"), prior and in preference to any declaration or payment of
     any dividend (payable other than in Common Stock of this Corporation) on
     the Common Stock of this Corporation. Such dividends on each share of
     Series A Preferred Stock shall be paid when and as declared by the Board of
     Directors; provided, however, that the Corporation shall neither declare
     nor pay a dividend on the shares of the Series A Preferred Stock unless,
     simultaneously therewith, the Corporation shall declare or pay a dividend
     on all outstanding series of Preferred Stock, each such dividend to be in
     an amount such that the amount of each such dividend bears the same
     proportionate relationship with the Stated Dividend Rate for each such
     series.  Such dividends shall not be cumulative.

          4.   Liquidation Preference.

          (a)  In the event of any liquidation, dissolution or winding up of
               this Corporation, either voluntary or involuntary, the holders of
               shares of Series A Preferred Stock shall be entitled to receive,
               prior and in preference to any distribution of any of the assets
               of this Corporation to the holders of the Common Stock, by reason
               of their ownership thereof, an amount per share equal to the sum
               of (i) $4.00 for each outstanding share of Series A Preferred
               Stock (the "Original Series A Issue Price") and (ii) an amount
               equal to $.0333 per share for each month that has passed since
               April 9, 1991 (such amount being referred to herein as the
               "Premium").  If upon the occurrence of such event, the assets and
               funds thus distributed among the holders of the Series A
               Preferred Stock shall be insufficient to permit the payment to
               such holders of the full aforesaid preferential amounts, then the
               entire assets and funds of the Corporation legally available for
               distribution shall be distributed ratably among the holders of
               the Series A Preferred Stock in proportion to the amount of such
               stock owned by each such holder, pari passu with the holders of
               any other series of Preferred Stock but in proportion to the
               respective amounts due the holders of each such series.

          (b)  Upon the completion of the distribution required by subsection
               4(a), if assets remain in this Corporation, the holders of the
               Series A Preferred Stock and Common Stock of this Corporation,
               shall receive all of the remaining assets of this Corporation,
               pro rata in accordance with the number of shares of Common Stock
               held by them or then issuable to them upon conversion of the
               Preferred Stock, pari passu with the holders of any other series
               of Preferred Stock.

                                     - 2 -

          (c)  A consolidation or merger of this Corporation with or into any
               other corporation(s), person(s), entity or entities, or any other
               corporate reorganization or a sale, conveyance or disposition of
               all or substantially all of the assets of this Corporation, in
               any transaction or series of related transactions, upon the
               effectiveness of which stockholders of this Corporation
               immediately prior thereto hold less than 51% of the voting power
               of the surviving corporation or entity shall, at the option of
               each holder of Series A Preferred Stock, be deemed to be a
               liquidation within the meaning of this Section 4 entitling such
               holder to all of the rights herein provided.

          5.   Redemption.

          (a)  On or at any time after March 31, 1998, this Corporation may at
               any time it may lawfully do so, at the option of the Board of
               Directors, redeem in whole or in part the Series A Preferred
               Stock by paying in cash therefor a sum equal to the Original
               Series A Issue Price per share, together with the Premium to the
               Redemption Date (as hereinafter defined) (such total amount is
               hereinafter referred to as the "Series A Redemption Price").
               Notwithstanding the foregoing, however, the Corporation shall not
               redeem in whole or in part the Series A Preferred Stock unless
               all shares of each series of Preferred Stock are redeemed pari
               passu in proportion to the respective amounts due the holders of
               each such series.

          (b)  On or at any time after the receipt by this Corporation from the
               holders of at least two-thirds (2/3) of the then outstanding
               shares of Series A Preferred Stock, of their written consent to
               redemption hereunder of their respective shares, this Corporation
               may at any time it may lawfully do so, at the option of the Board
               of Directors, redeem in whole or in part the Series A Preferred
               Stock by paying in cash therefor a sum equal to the Series A
               Redemption Price.

     (c)  (i)  In the event of any redemption of only a part of the then
               outstanding Series A Preferred Stock, this Corporation shall
               effect such redemption pro rata according to the number of shares
               held by each holder thereof.

               (ii)   At least 30 but no more than 60 days prior to the date
                      fixed for any redemption of Series A Preferred Stock (the
                      "Redemption Date"), written notice shall be given by
                      mailing, postage prepaid, to each holder of record (at the
                      close of business on the business day next preceding the
                      day on which notice is given) of the Series A Preferred
                      Stock to be redeemed, at the address last shown on the
                      records of this

                                     - 3 -
<PAGE>
 
                      Corporation for such holder or given by the holder to this
                      Corporation for the purpose of notice, or if no such
                      address appears or is given at the place where the
                      principal executive office of this Corporation is located,
                      notifying such holder of the redemption to be effected,
                      specifying the Redemption Date, the Redemption Price, the
                      place at which payment may be obtained and the date on
                      which such holder's Conversion Rights (as hereinafter
                      defined) as to such shares terminate and calling upon such
                      holder to surrender to this Corporation, in the manner and
                      at the place designated, his certificate or certificates
                      representing the shares to be redeemed (the "Redemption
                      Notice"). The Redemption Notice shall be sufficiently
                      given only when and if received by each such holder of
                      record. Except as provided in subsection 5(c)(iii), on or
                      after the Redemption Date, each holder of Preferred Stock
                      to be redeemed shall surrender to this Corporation the
                      certificate or certificates representing such shares, in
                      the manner and at the place designated in the Redemption
                      Notice, and thereupon the Redemption Price of such shares
                      shall be payable to the order of the person whose name
                      appears on such certificate or certificates at the owner
                      thereof and each surrendered certificate shall be
                      canceled. In the event less than all the shares
                      represented by any such certificate are redeemed, a new
                      certificate shall be issued representing the unredeemed
                      shares.

               (iii)  From and after the Redemption Date, unless there shall
                      have been a default in payment of the Redemption Price,
                      all dividends on the Series A Preferred Stock designated
                      for redemption in the Redemption Notice shall cease to
                      accrue, all rights of the holders of such shares as
                      holders of Series A Preferred Stock (except the right to
                      receive the Redemption Price without interest upon
                      surrender of their certificate or certificates) shall
                      cease with respect to such shares, and such shares shall
                      not thereafter be transferred on the books of this
                      Corporation or be deemed to be outstanding for any purpose
                      whatsoever. If the funds of the Corporation legally
                      available for redemption of shares of Series A Preferred
                      Stock on any Redemption Date are insufficient to redeem
                      the total number of shares of Series A Preferred Stock to
                      be redeemed on such date, those funds which are legally
                      available will be used to redeem the maximum possible
                      number of such shares ratably among the holders of such
                      shares to be redeemed. The shares of Series A Preferred
                      Stock not redeemed shall remain outstanding and entitled
                      to all the rights and preferences provided herein. At any
                      time thereafter when additional funds of the Corporation
                      are legally available for the redemption of shares of

                                     - 4 -
<PAGE>
 
                      Series A Preferred Stock, such funds will immediately be
                      used to redeem the balance of the shares which the
                      Corporation has become obligated to redeem on any
                      Redemption Date but which it has not redeemed.

               (iv)   Three days prior to the Redemption Date, this Corporation
                      shall deposit the Redemption Price of all outstanding
                      shares of Series A Preferred Stock designated for
                      redemption of the Redemption Notice, and not yet redeemed
                      or converted, with a bank or trust company having
                      aggregate capital and surplus in excess of $50,000,000 as
                      a trust fund for the benefit of the respective holders of
                      the shares designated for redemption and not yet redeemed.
                      Simultaneously, this Corporation shall deposit irrevocable
                      instruction and authority to such bank or trust company to
                      publish the notice of redemption thereof (or to complete
                      such publication if theretofore commenced) and to pay, on
                      and after the date fixed for redemption or prior thereto,
                      the Redemption Price of the Series A Preferred Stock to
                      the holders thereof upon surrender of their certificates.
                      Any moneys deposited by this Corporation pursuant to this
                      subsection 5(c)(iv) for the redemption of shares which are
                      thereafter converted into shares of Common Stock pursuant
                      to Section 6 hereof no later than the close of business on
                      the Redemption Date shall be returned to this Corporation
                      forthwith upon such conversion. The balance of any moneys
                      deposited by this Corporation pursuant to this subsection
                      5(c)(iv) remaining unclaimed at the expiration of two
                      years following the Redemption Date shall thereafter be
                      returned to this Corporation upon its request expressed in
                      a resolution of its Board of Directors, provided that the
                      stockholder(s) to which such monies would be payable
                      hereunder shall be entitled, upon proof of its ownership
                      of the Series A Preferred Stock and payment of any bond
                      requested by the Corporation, to receive such monies but
                      without interest from the Redemption Date.

          6.   Conversion.  The holders of the Series A Preferred Stock shall
     have conversion rights as follows (the "Conversion Rights"):

          (a)  Right to Convert.

               (i)    Subject to subsection 6(c), each shares of Series A
                      Preferred Stock shall be convertible, at the option of the
                      holder thereof, at any time and from time to time after
                      the date of issuance of such share and prior to the close
                      of business on the

                                     - 5 -
<PAGE>
 
                      Redemption Date as may have been fixed in any Redemption
                      Notice with respect to such share, at the office of this
                      Corporation or any transfer agent for the Series A
                      Preferred Stock, into such number of fully paid and
                      nonassessable shares of Common Stock as is determined by
                      dividing the Original Series A Issue Price by the
                      Conversion Price at the time in effect for such share. The
                      initial Conversion Price per share for shares of Series A
                      Preferred Stock shall be the Original Series A Issue Price
                      (i.e., $4.00 per share); provided, however, that the
                      Conversion Price for the Series A Preferred Stock shall be
                      subject to adjustment as set forth in subsection 6(c).

               (ii)   In the event of a call for redemption of any shares of
                      Series A Preferred Stock pursuant to Section 5 hereof, the
                      Conversion Rights shall terminate as to the shares
                      designated for redemption at the close of business on the
                      Redemption Date, unless default is made in payment of the
                      Redemption Price.

               (iii)  Each share of Series A Preferred Stock shall automatically
                      be converted into shares of Common Stock as is determined
                      by dividing the original Series A Issue Price by the
                      Conversion Price at the time in effect for such Series A
                      Preferred Stock immediately upon the consummation of the
                      Corporation's sale of its Common Stock in a bona fide,
                      firm commitment underwriting pursuant to a Registration
                      Statement on Form S-1, or its equivalent, under the
                      Securities Act of 1933, as amended, which results in
                      aggregate cash proceeds to this Corporation of in excess
                      of $10,000,000, and the public offering price of which was
                      not less than $6.00 per share (adjusted to reflect
                      subsequent changes in the capitalization of the
                      Corporation). Such automatic conversion shall not be
                      effected with respect to any shares of Series A Preferred
                      Stock which this Corporation shall have elected to redeem
                      pursuant to the provisions of Section 5 hereof.

               (iv)   In the event of any Future Equity Financing (as defined
                      below), a portion of the shares of Series A Preferred
                      Stock held by any holder (a "Non-Participating Holder")
                      who does not acquire its full pro rata share of such
                      Future Equity Financing (determined by multiplying the
                      aggregate number of equity securities to be sold by the
                      Corporation in connection with the Future Equity Financing
                      by a fraction, the numerator of which is the number of
                      shares of Series A Preferred Stock held by the Non-
                      Participating Holder and the denominator is the aggregate
                      number of shares of Series A

                                     - 6 -
<PAGE>
 
                      Preferred Stock outstanding immediately prior to the date
                      such Future Equity Financing is consummated) shall
                      automatically be converted into shares of Common Stock at
                      the then current Conversion Price. The number of shares of
                      the Non-Participating Holder's Series A Preferred Stock to
                      be automatically converted into shares of Common Stock
                      shall be determined by multiplying the number of shares of
                      Series A Preferred Stock held by the Non-Participating
                      Holder by a fraction, the numerator of which is the amount
                      of the Non-Participating Holder's pro rata share
                      (determined in accordance with the formula set forth
                      above) of the equity securities to be sold in connection
                      with the Future Equity Financing which are not purchased
                      by the Non-Participating Holder and the denominator of
                      which is the Non-Participating Holder's pro rata share of
                      the equity securities to be sold in connection with the
                      Future Equity Financing. The term "Future Equity
                      Financing" shall mean any equity financing of the
                      Corporation occurring after August 7, 1991, excluding: (i)
                      sales of equity securities of the Corporation in a single
                      financing transaction in which the aggregate sales price
                      of such equity securities is greater than $6,000,000; (ii)
                      sales of equity securities of the Corporation in a single
                      financing transaction in which the aggregate sales price
                      of such securities is equal to or greater than $1,000,000,
                      the price per share of such equity securities (adjusted to
                      appropriately reflect any stock dividend, stock split,
                      reverse stock split, share combination, reorganization,
                      recapitalization or the like, of or by the Corporation) is
                      $.20 or greater, and pursuant to which neither any then
                      existing holder of shares of Series A Preferred Stock nor
                      any affiliate thereof purchases any of such equity
                      securities; and (iii) any transaction exempted from the
                      right of refusal set forth in Section 9.5 of the
                      Corporation's Series A Preferred Stock Purchase Agreement
                      dated as of April 10, 1991, as amended from time to time
                      (the "Series A Agreement") pursuant to the provisions of
                      Subsection 9.5(d) of the Series A Agreement.

          (b)  Mechanics of Conversion.  Before any holder of Series A Preferred
               Stock shall be entitled to convert the same into shares of Common
               Stock, he shall surrender the certificate or certificates
               therefor, duly endorsed, at the office of this Corporation or of
               any transfer agent for the Series A Preferred Stock, and shall
               give written notice by mail, postage prepaid, to this Corporation
               at its principal corporate office, of the election to convert the
               same and shall state therein the name or names in which the
               certificate or certificates for shares of Common 

                                     - 7 -

               Stock are to be issued. This Corporation shall, as soon as
               practicable thereafter, issue and deliver at such office to such
               holder of Series A Preferred Stock, or to the nominee or nominees
               of such holder, a certificate or certificates for the number of
               shares of Common Stock to which such holder shall be entitled as
               aforesaid. Such conversion shall be deemed to have been made
               immediately prior to the close of business on the date of such
               surrender of the shares of Series A Preferred Stock to be
               converted, and the person or persons entitled to receive the
               shares of Common Stock issuable upon such conversion shall be
               treated for all purposes as the record holder or holders of such
               shares of Common Stock as of such date.

          (c)  Conversion Price Adjustments of Preferred Stock. The Conversion
               Price of the Series A Preferred Stock shall be subject to
               adjustment from time to time as follows:

               (i)  (A)  If the Corporation shall issue any Additional Stock (as
                         defined below) without consideration or for a
                         consideration per share less than the Conversion Price
                         for the Series A Preferred Stock in effect immediately
                         prior to the issuance of such Additional Stock, the
                         Conversion Price shall be reduced to a price equal to
                         the consideration per share, if any, received by the
                         Corporation upon such issue.

                    (B)  No adjustment of the Conversion Price for the Series A
                         Preferred Stock shall be made in an amount less than
                         one cent per share, provided that any adjustments which
                         are not required to be made by reason of this sentence
                         shall be carried forward and shall be either taken into
                         account in any subsequent adjustment made prior to
                         three years from the date of the event giving rise to
                         the adjustment being carried forward, or shall be made
                         at the end of three years from the date of the event
                         giving rise to the adjustment being carried forward.
                         Except to the limited extent provided for in
                         subsections 6(c)(i)(E)(3) and (c)(i)(E)(4) no
                         adjustment of such Conversion Price shall have the
                         effect of increasing the Conversion Price above the
                         Conversion Price in effect immediately prior to such
                         adjustment.

                    (C)  In the case of the issuance of Common Stock for cash,
                         the consideration shall be deemed to be the amount of
                         cash paid therefor before deducting any reasonable

                                     - 8 -

                         discounts, commissions or other expenses allowed, paid
                         or incurred by this Corporation for any underwriting or
                         otherwise in connection with the issuance and sale
                         thereof.

                    (D)  In the case of the issuance of the Common Stock for a
                         consideration in whole or in part other than cash, the
                         consideration other than cash shall be deemed to be the
                         fair value thereof as determined by the Board of
                         Directors irrespective of any accounting treatment.

                    (E)  In the case of the issuance of options to purchase or
                         rights to subscribe for Common Stock, securities by
                         their terms convertible into or exchangeable for Common
                         Stock or options to purchase or rights to subscribe for
                         such convertible or exchangeable securities (which are
                         not excluded from the definition of Additional Stock),
                         the following provisions shall apply:

                         1.   The aggregate maximum number of shares of Common
                              Stock deliverable upon exercise of such options to
                              purchase or rights to subscribe for Common Stock
                              shall be deemed to have been issued at the time
                              such options or rights were issued and for a
                              consideration equal to the consideration
                              (determined in the manner provided in Subsections
                              6(c)(i)(C) and (c)(i)(D)), if any, received by the
                              Corporation upon the issuance of such options or
                              rights plus the minimum purchase price provided in
                              such options or rights for the Common Stock
                              covered thereby.

                         2.   The aggregate maximum number of shares of Common
                              Stock deliverable upon conversion of or in
                              exchange for any such convertible or exchangeable
                              securities and subsequent conversion or exchange
                              thereof shall be deemed to have been issued at the
                              time such securities were issued or such options
                              or rights were issued and for a consideration
                              equal to the consideration, if any, received by
                              the Corporation for any such securities and
                              related options or rights (excluding any cash
                              received

                              dividends), plus the additional consideration, if
                              any, to be received by the Corporation upon the
                              conversion or exchange of such securities or the
                              exercise of any related options or rights (the
                              consideration in each case to be determined in the
                              manner provided in subsections 6(c)(i)(C) and
                              (c)(i)(D).

                         3.   In the event of any change in the number of shares
                              of Common Stock deliverable upon exercise of such
                              options or rights or upon conversion of or in
                              exchange for such convertible or exchangeable
                              securities, including, but not limited to, a
                              change resulting from the antidilution provisions
                              thereof, the Conversion Price in effect at the
                              time for the Series A Preferred Stock shall
                              forthwith be readjusted to such Conversion Price
                              as would have obtained had the adjustment which
                              was made upon the issuance of such options, rights
                              or securities not converted prior to such change
                              or the options or rights related to such
                              securities not converted prior to such change been
                              made upon the basis of such change, but no further
                              adjustment shall be made for the actual issuance
                              of Common Stock upon the exercise of any such
                              options or rights or the conversion or exchange of
                              such securities.

                         4.   Upon the expiration of any such options or rights,
                              the termination of any such rights to convert or
                              exchange or the expiration of any options or
                              rights related to such convertible or exchangeable
                              securities, the Conversion Price for the Series A
                              Preferred Stock shall forthwith be readjusted to
                              such Conversion Price as would have obtained had
                              the adjustment which was made upon the issuance of
                              such options, rights or securities or options or
                              rights related to such securities been made upon
                              the basis of the issuance of only the number of
                              shares of Common Stock actually issued upon the
                              exercise of such options or

                              rights, upon the conversion or exchange of such
                              securities or upon the exercise of the options or
                              rights related to such securities.

               (ii)   "Additional Stock" shall mean any shares of Common Stock
                      issued (or deemed to have been issued pursuant to
                      subsection 6(c)(i)(E)) by this Corporation after April 9,

                           persons or entities including options therefor

                      (C)  In addition to the shares of Common Stock provided in

                           (excluding shares repurchased by the Corporation),
                           including options or warrants therefor issuable or
                           issued from time to time in the discretion of the

                      (E)  Common Stock issued or issuable upon the exercise of
                           those certain warrants issued by the Corporation to

                           antidilution provisions of such warrants or options
                           previously issued by the Corporation or by amendment
                           thereto in satisfaction of such antidilution
                           provisions.

          (iii)  In the event the Corporation should at any time or from time to
                 time after April 9, 1991 fix a record date for the effectuation
                 of a split or subdivision of the outstanding shares of Common
                 Stock or the determination of holders of Common Stock entitled
                 to receive a dividend or other distribution payable in
                 additional shares of Common Stock or other securities or rights
                 convertible into, or entitling the holder thereof to receive
                 directly or indirectly, additional shares of Common Stock
                 (hereinafter referred to as "Common Stock Equivalents") without
                 payment of any consideration by such holder for the additional
                 shares of Common Stock or the Common Stock Equivalents
                 (including the additional shares of Common Stock issuable upon
                 conversion or exercise thereof), then, as of such record date
                 (or the date of such dividend distribution, split or
                 subdivision if no record date is fixed), the Conversion Price
                 of the Series A Preferred Stock shall be appropriately
                 decreased so that the number of shares of Common Stock issuable
                 on conversion of such series shall be increased in proportion
                 to such increase of outstanding shares determined in accordance
                 with subsection 6(c)(i)(E).

          (iv)   If the number of shares of Common Stock outstanding at any time
                 after April 9, 1991 is decreased by a combination of the
                 outstanding shares of Common Stock, then, following the record
                 date of such combination, the Conversion Price for the Series A
                 Preferred Stock shall be appropriately increased so that the
                 number of shares of Common Stock issuable on conversion of such
                 series shall be decreased in proportion to such decrease in
                 outstanding shares.

          (d)    Other Distributions. In the event this Corporation shall
                 declare a distribution payable in securities of other persons,
                 evidences of indebtedness issued by this Corporation or other
                 persons, assets (excluding cash dividends) or options or rights
                 not referred to in subsection 6(c)(iii), then, in each such
                 case for the purpose of this subsection 6(d), the holders of
                 the Series A Preferred Stock shall be entitled to a
                 proportionate share of any such distribution as though they
                 were the holders of the number of shares of Common Stock of the
                 Corporation into which their shares of Series A Preferred Stock
                 are convertible as of the record date fixed for the
                 determination of the holders of Common Stock of the Corporation
                 entitled to receive such distribution.

          (e)    Recapitalizations. If at any time or from time to time there
                 shall be a recapitalization of the Common Stock (other than a
                 subdivision, combination or merger or sale of assets
                 transaction provided for elsewhere in this Section 6 or Section
                 4), provision shall be made so that the holders of the Series A
                 Preferred Stock shall thereafter be entitled to receive upon
                 conversion of the Series A Preferred Stock the number of shares
                 of stock or other securities or property of this Corporation or
                 otherwise, to which a holder of Common Stock deliverable upon
                 conversion would have been entitled on such recapitalization.
                 In any such case, appropriate adjustment shall be made in the
                 application of the provisions of this Section 6 with respect to
                 the rights of the holders of the Series A Preferred Stock after
                 the recapitalization to the end that the provisions of this
                 Section 6 (including adjustment of the Conversion Price then in
                 effect and the number of shares purchasable upon conversion of
                 the Series A Preferred Stock) shall be applicable after that
                 event as nearly equivalent as may be practicable.

          (f)    No Impairment. This Corporation will not, by amendment of its
                 Certificate of Incorporation or through any reorganization,
                 recapitalization, transfer of assets, consolidation, merger,
                 dissolution, issue or sale of securities or any other voluntary
                 action, avoid or seek to avoid the observance or performance of
                 any of the terms to be observed or performed hereunder by this
                 Corporation, but will at all times in good faith assist in the
                 carrying out of all the provisions of this Section 6 and in the
                 taking of all such action as may be necessary or appropriate in
                 order to protect the Conversion Rights of the holders of the
                 Series A Preferred Stock against impairment.

          (g)    No Fractional Shares and Certificate as to Adjustments.

                 (i)    No fractional shares shall be issued upon conversion of
                        the Series A Preferred Stock, and the number of shares
                        of Common Stock to be issued shall be rounded to the
                        nearest whole share. Whether or not fractional shares
                        are issuable upon such conversion shall be determined on
                        the basis of the total number of shares of Series A
                        Preferred Stock the holder is at the time converting
                        into Common Stock and the number of shares of Common
                        Stock issuable upon such aggregate conversion.
                 (ii)   Upon the occurrence of each adjustment or readjustment
                        of the Conversion Price of Series A Preferred Stock
                        pursuant to this Section 6, this Corporation, at its
                        expense, shall promptly compute such adjustment or
                        readjustment in accordance with the terms hereof and,
                        through its chief financial officer,

                                     - 13 -

                        certify such computation and prepare and furnish to each
                        holder of Series A Preferred Stock a certificate setting
                        forth such adjustment or readjustment and showing in
                        detail the facts upon which such adjustment or
                        readjustment is based. This Corporation shall, upon the
                        written request at any time of any holder of Series A
                        Preferred Stock, furnish or cause to be furnished to
                        such holder a like certificate setting forth (A) such
                        adjustment and readjustment, (B) the Conversion Price at
                        the time in effect, and (C) the number of shares of
                        Common Stock and the amount, if any, of other property
                        which at the time would be received upon the conversion
                        of a share of Series A Preferred Stock.

          (h)  Notices of Record Date. In the event of any taking by this
               Corporation of a record of the holders of any class of securities
               for the purpose of determining the holders thereof who are
               entitled to receive any dividend (other than a cash dividend) or
               other distribution, any right to subscribe for, purchase or
               otherwise acquire any shares of stock of any class or any other
               securities or property, or to receive any other right, this
               Corporation shall mail to each holder of Series A Preferred
               Stock, at least 20 days prior to the date specified therein, a
               notice specifying the date on which any such record is to be
               taken for the purpose of such dividend, distribution or right,
               and the amount and character of such dividend, distribution or
               right.

          (i)  Reservation of Stock Issuable Upon Conversion.  This Corporation
               shall at all times reserve and keep available out of its
               authorized but unissued shares of Common Stock solely for the
               purpose of effecting the conversion of the shares of the Series A
               Preferred Stock such number of its shares of Common Stock as
               shall from time to time be sufficient to effect the conversion of
               all outstanding shares of the Series A Preferred Stock; and if at
               any time the number of authorized but unissued shares of Common
               Stock shall not be sufficient to effect the conversion of all
               then outstanding shares of the Series A Preferred Stock, this
               Corporation will take such corporate action as may, in the
               opinion of its counsel, be necessary to increase its authorized
               but unissued shares of Common Stock to such number of shares as
               shall be sufficient for such purposes.

          (j)  Notices.  Any notice required by the provisions of this Section 6
               to be given to the holders of shares of Series A Preferred Stock
               shall be deemed given if deposited in the United States mail,
               postage prepaid, and addressed to each holder of record at his
               address appearing on the books of this Corporation.

          7.   Voting Rights.  The holder of each share of Series A Preferred
     Stock shall have the right to one vote for each share of Common Stock into
     which such Series A Preferred Stock could then be converted (with any
     fractional share determined on an aggregate conversion basis being rounded
     to the nearest whole share), and with respect to such vote, such holder
     shall have full voting rights and powers equal to the voting rights and
     powers of the holders of Common Stock, and shall be entitled,
     notwithstanding any provision hereof, to notice of any stockholders'
     meeting in accordance with the Bylaws of this Corporation, and shall be
     entitled to vote, together with holders of Common Stock, with respect to
     any question upon which holders of Common Stock have the right to vote, as
     a single class (except to the extent class voting is otherwise required by
     applicable law).

          8.   Status of Redeemed or Converted Stock. In the event any shares of
     Series A Preferred Stock shall be redeemed or converted pursuant to Section
     5 or Section 6 hereof, or reacquired by the Corporation in any manner and
     retired, such shares shall have the status of authorized and unissued
     shares of Preferred Stock without designation and may be redesignated by
     the Board of Directors as shares of the same or any other series.

          (c)  Designation, Rights, Preferences and Power of the Series B
     Preferred Stock.

          1.   Designation.  The second series of Preferred Stock shall be
     designated "Series B Preferred Stock."

          2.   Authorized Number. The number of shares constituting the Series B
     Preferred Stock shall be 3,250,000 shares, which number may be increased or
     decreased from time to time (but not decreased below the number of shares
     then outstanding) by the Board of Directors pursuant to the provisions of
     the Corporation's Restated Certificate of Incorporation.

          3.   Dividend Provisions.  The holders of shares of Series B Preferred
     Stock shall be entitled to receive dividends, out of the assets legally
     available therefor, at the rate of $.40 per share per annum (the "Stated
     Dividend Rate"), prior and in preference to any declaration or payment of
     any dividend (payable other than in Common Stock of this Corporation) on
     the Common Stock of this Corporation.  Such dividends on each share of
     Series B Preferred Stock shall be paid when and as declared by the Board of
     Directors; provided, however, that the Corporation shall neither declare
     nor pay a dividend on the shares of the Series B Preferred Stock unless,
     simultaneously therewith, the Corporation shall declare or pay a dividend
     on all outstanding series of Preferred Stock, each such dividend to be in
     an amount such that the amount of each such dividend bears the same
     proportionate relationship with the Stated Dividend Rate for each such
     series. Such dividends shall not be cumulative.

          4.   Liquidation Preference.

          (a)  In the event of any liquidation, dissolution or winding up of
               this Corporation, either voluntary or involuntary, the holders of
               shares of Series B Preferred Stock shall be entitled to receive,
               prior and in preference to any distribution of any of the assets
               of this Corporation to the holders of the Common Stock, by reason
               of their ownership thereof, an amount per share equal to the sum
               of (i) $4.00 for each outstanding share of Series B Preferred
               Stock (the "Original Series B Issue Price") and (ii) an amount
               equal to $.0333 per share for each month that has passed since
               October 19, 1992 (such amount being referred to herein as the
               "Premium").  If upon the occurrence of such event, the assets and
               funds thus distributed among the holders of the Series B
               Preferred Stock shall be insufficient to permit the payment to
               such holders of the full aforesaid preferential amounts, then the
               entire assets and funds of the Corporation legally available for
               distribution shall be distributed ratably among the holders of
               the Series B Preferred Stock in proportion to the amount of such
               stock owned by each such holder, pari passu with the holders of
               any other series of Preferred Stock but in proportion to the
               respective amounts due the holders of each such series.

          (b)  Upon the completion of the distribution required by subsection
               4(a), if assets remain in this Corporation, the holders of the
               Series B Preferred Stock and Common Stock of this Corporation,
               shall receive all of the remaining assets of this Corporation,
               pro rata in accordance with the number of shares of Common Stock
               held by them or then issuable to them upon conversion of the
               Preferred Stock, pari passu with the holders of any other series
               of Preferred Stock.

          (c)  A consolidation or merger of this Corporation with or into any
               other corporation(s), person(s), entity or entities, or any other
               corporate reorganization or a sale, conveyance or disposition of
               all or substantially all of the assets of this Corporation, in
               any transaction or series of related transactions, upon the
               effectiveness of which stockholders of this Corporation
               immediately prior thereto hold less than 51% of the voting power
               of the surviving corporation or entity shall, at the option of
               each holder of Series B Preferred Stock, be deemed to be a
               liquidation within the meaning of this Section 4 entitling such
               holder to all of the rights herein provided.

          5.   Redemption.

                                     - 16 -

          (a)  On or at any time after March 31, 1999, this Corporation may at
               any time it may lawfully do so, at the option of the Board of
               Directors, redeem in whole or in part the Series B Preferred
               Stock by paying in cash therefor a sum equal to the Original
               Series B Issue Price per share, together with the Premium to the
               Redemption Date (as hereinafter defined) (such total amount is
               hereinafter referred to as the "Series B Redemption Price").
               Notwithstanding the foregoing, however, the Corporation shall not
               redeem in whole or in part the Series B Preferred Stock unless
               all shares of each series of Preferred Stock are redeemed pari
               passu in proportion to the respective amounts due the holders of
               each such series.

          (b)  On or at any time after the receipt by this Corporation from the
               holders of at least two-thirds (2/3) of the then outstanding
               shares of Series B Preferred Stock, of their written consent to
               redemption hereunder of their respective shares, this Corporation
               may at any time it may lawfully do so, at the option of the Board
               of Directors, redeem in whole or in part the Series B Preferred
               Stock by paying in cash therefor a sum equal to the Series B
               Redemption Price.

          (c)  (i)    In the event of any redemption of only a part of the then
                      outstanding Series B Preferred Stock, this Corporation
                      shall effect such redemption pro rata according to the
                      number of shares held by each holder thereof.

               (ii)   At least 30 but no more than 60 days prior to the date
                      fixed for any redemption of Series B Preferred Stock (the
                      "Redemption Date"), written notice shall be given by
                      mailing, postage prepaid, to each holder of record (at the
                      close of business on the business day next preceding the
                      day on which notice is given) of the Series B Preferred
                      Stock to be redeemed, at the address last shown on the
                      records of this Corporation for such holder or given by
                      the holder to this Corporation for the purpose of notice,
                      or if no such address appears or is given at the place
                      where the principal executive office of this Corporation
                      is located, notifying such holder of the redemption to be
                      effected, specifying the Redemption Date, the Redemption
                      Price, the place at which payment may be obtained and the
                      date on which such holder's Conversion Rights (as
                      hereinafter defined) as to such shares terminate and
                      calling upon such holder to surrender to this Corporation,
                      in the manner and at the place designated, his certificate
                      or certificates representing the shares to be redeemed
                      (the "Redemption Notice"). The

                                     - 17 -
<PAGE>
 
                      Redemption Notice shall be sufficiently given only when
                      and if received by each such holder of record. Except as
                      provided in subsection 5(c)(iii), on or after the
                      Redemption Date, each holder of Preferred Stock to be
                      redeemed shall surrender to this Corporation the
                      certificate or certificates representing such shares, in
                      the manner and at the place designated in the Redemption
                      Notice, and thereupon the Redemption Price of such shares
                      shall be payable to the order of the person whose name
                      appears on such certificate or certificates as the owner
                      thereof and each surrendered certificate shall be
                      canceled. In the event less than all the shares
                      represented by any such certificate are redeemed, a new
                      certificate shall be issued representing the unredeemed
                      shares.

               (iii)  From and after the Redemption Date, unless there shall
                      have been a default in payment of the Redemption Price,
                      all dividends on the Series B Preferred Stock designated
                      for redemption in the Redemption Notice shall cease to
                      accrue, all rights of the holders of such shares as
                      holders of Series B Preferred Stock (except the right to
                      receive the Redemption Price without interest upon
                      surrender of their certificate or certificates) shall
                      cease with respect to such shares, and such shares shall
                      not thereafter be transferred on the books of this
                      Corporation or be deemed to be outstanding for any purpose
                      whatsoever. If the funds of the Corporation legally
                      available for redemption of shares of Series B Preferred
                      Stock on any Redemption Date are insufficient to redeem
                      the total number of shares of Series B Preferred Stock to
                      be redeemed on such date, those funds which are legally
                      available will be used to redeem the maximum possible
                      number of such shares ratably among the holders of such
                      shares to be redeemed. The shares of Series B Preferred
                      Stock not redeemed shall remain outstanding and entitled
                      to all the rights and preferences provided herein. At any
                      time thereafter when additional funds of the Corporation
                      are legally available for the redemption of shares of
                      Series B Preferred Stock, such funds will immediately be
                      used to redeem the balance of the shares which the
                      Corporation has become obligated to redeem on any
                      Redemption Date but which it has not redeemed.

               (iv)   Three days prior to the Redemption Date, this Corporation
                      shall deposit the Redemption Price of all outstanding
                      shares of Series B Preferred Stock designated for
                      redemption of the Redemption Notice, and not yet redeemed
                      or converted, with a bank or trust company having
                      aggregate capital and surplus in excess of $50,000,000 as
                      a trust fund for the

                                     - 18 -
<PAGE>
 
                      benefit of the respective holders of the shares designated
                      for redemption and not yet redeemed. Simultaneously, this
                      Corporation shall deposit irrevocable instruction and
                      authority to such bank or trust company to publish the
                      notice of redemption thereof (or to complete such
                      publication if theretofore commenced) and to pay, on and
                      after the date fixed for redemption or prior thereto, the
                      Redemption Price of the Series B Preferred Stock to the
                      holders thereof upon surrender of their certificates. Any
                      moneys deposited by this Corporation pursuant to this
                      subsection 5(c)(iv) for the redemption of shares which are
                      thereafter converted into shares of Common Stock pursuant
                      to Section 6 hereof no later than the close of business on
                      the Redemption Date shall be returned to this Corporation
                      forthwith upon such conversion. The balance of any moneys
                      deposited by this Corporation pursuant to this subsection
                      5(c)(iv) remaining unclaimed at the expiration of two
                      years following the Redemption Date shall thereafter be
                      returned to this Corporation upon its request expressed in
                      a resolution of its Board of Directors, provided that the
                      stockholder(s) to which such monies would be payable
                      hereunder shall be entitled, upon proof of its ownership
                      of the Series B Preferred Stock and payment of any bond
                      requested by the Corporation, to receive such monies but
                      without interest from the Redemption Date.

          6.   Conversion.  The holders of the Series B Preferred Stock shall
     have conversion rights as follows (the "Conversion Rights"):

          (a)  Right to Convert.

               (i)    Subject to subsection 6(c), each share of Series B
                      Preferred Stock shall be convertible, at the option of the
                      holder thereof, at any time and from time to time after
                      the date of issuance of such share and prior to the close
                      of business on the Redemption Date as may have been fixed
                      in any Redemption Notice with respect to such share, at
                      the office of this Corporation or any transfer agent for
                      the Series B Preferred Stock, into such number of fully
                      paid and nonassessable shares of Common Stock as is
                      determined by dividing the Original Series B Issue Price
                      by the Conversion Price at the time in effect for such
                      share. The initial Conversion Price per share for shares
                      of Series B Preferred Stock shall be the Original Series B
                      Issue Price (i.e., $4.00 per share); provided, however,
                      that the Conversion Price for

                                     - 19 -
<PAGE>
 
                      the Series B Preferred Stock shall be subject to
                      adjustment as set forth in subsection 6(c).

               (ii)   In the event of a call for redemption of any shares of
                      Series B Preferred Stock pursuant to Section 5 hereof, the
                      Conversion Rights shall terminate as to the shares
                      designated for redemption at the close of business on the
                      Redemption Date, unless default is made in payment of the
                      Redemption Price.

               (iii)  Each share of Series B Preferred Stock shall automatically
                      be converted into shares of Common Stock as is determined
                      by dividing the original Series B Issue Price by the
                      Conversion Price at the time in effect for such Series B
                      Preferred Stock immediately upon the consummation of the
                      Corporation's sale of its Common Stock in a bona fide,
                      firm commitment underwriting pursuant to a Registration
                      Statement on Form S-1, or its equivalent, under the
                      Securities Act of 1933, as amended, which results in
                      aggregate cash proceeds to this Corporation of in excess
                      of $10,000,000, and the public offering price of which was
                      not less than $6.00 per share (adjusted to reflect
                      subsequent changes in the capitalization of the
                      Corporation). Such automatic conversion shall not be
                      effected with respect to any shares of Series B Preferred
                      Stock which this Corporation shall have elected to redeem
                      pursuant to the provisions of Section 5 hereof.

          (b)  Mechanics of Conversion.  Before any holder of Series B Preferred
               Stock shall be entitled to convert the same into shares of Common
               Stock, he shall surrender the certificate or certificates
               therefor, duly endorsed, at the office of this Corporation or of
               any transfer agent for the Series B Preferred Stock, and shall
               give written notice by mail, postage prepaid, to this Corporation
               at its principal corporate office, of the election to convert the
               same and shall state therein the name or names in which the
               certificate or certificates for shares of Common Stock are to be
               issued.  This Corporation shall, as soon as practicable
               thereafter, issue and deliver at such office to such holder of
               Series B Preferred Stock, or to the nominee or nominees of such
               holder, a certificate or certificates for the number of shares of
               Common Stock to which such holder shall be entitled as aforesaid.
               Such conversion shall be deemed to have been made immediately
               prior to the close of business on the date of such surrender of
               the shares of Series B Preferred Stock to be converted, and the
               person or persons entitled to receive the shares of Common 

                                     - 20 -
<PAGE>
 
               Stock issuable upon such conversion shall be treated for all
               purposes as the record holder or holders of such shares of Common
               Stock as of such date.

          (c)  Conversion Price Adjustments of Preferred Stock. The Conversion
               Price of the Series B Preferred Stock shall be subject to
               adjustment from time to time as follows:

               (i)  (A)  If the Corporation shall issue any Additional Stock (as
                         defined below) without consideration or for a
                         consideration per share less than the Conversion Price
                         for the Series B Preferred Stock in effect immediately
                         prior to the issuance of such Additional Stock, the
                         Conversion Price shall be reduced to a price equal to
                         the consideration per share, if any, received by the
                         Corporation upon such issue.

                    (B)  No adjustment of the Conversion Price for the Series B
                         Preferred Stock shall be made in an amount less than
                         one cent per share, provided that any adjustments which
                         are not required to be made by reason of this sentence
                         shall be carried forward and shall be either taken into
                         account in any subsequent adjustment made prior to
                         three years from the date of the event giving rise to
                         the adjustment being carried forward, or shall be made
                         at the end of three years from the date of the event
                         giving rise to the adjustment being carried forward.
                         Except to the limited extent provided for in
                         subsections 6(c)(i)(E)(3) and (c)(i)(E)(4) no
                         adjustment of such Conversion Price shall have the
                         effect of increasing the Conversion Price above the
                         Conversion Price in effect immediately prior to such
                         adjustment.

                    (C)  In the case of the issuance of Common Stock for cash,
                         the consideration shall be deemed to be the amount of
                         cash paid therefor before deducting any reasonable
                         discounts, commissions or other expenses allowed, paid
                         or incurred by this Corporation for any underwriting or
                         otherwise in connection with the issuance and sale
                         thereof.

                    (D)  In the case of the issuance of the Common Stock for a
                         consideration in whole or in part other than cash, the
                         consideration other than cash shall be deemed to 

                                     - 21 -
<PAGE>
 
                         be the fair value thereof as determined by the Board of
                         Directors irrespective of any accounting treatment.

                    (E)  In the case of the issuance of options to purchase or
                         rights to subscribe for Common Stock, securities by
                         their terms convertible into or exchangeable for Common
                         Stock or options to purchase or rights to subscribe for
                         such convertible or exchangeable securities (which are

                      or other securities or rights convertible into, or
                      entitling the holder thereof to receive directly or
                      indirectly, additional shares of Common Stock (hereinafter
                      referred to as "Common Stock Equivalents") without payment
                      of any consideration by such holder for the additional

                      (including the additional shares of Common Stock issuable
                      upon conversion or exercise thereof), then, as of such
                      record date (or the date of such dividend distribution,
                      split or subdivision if no record date is fixed), the

                      time after October 19, 1992 is decreased by a combination

                      increased so that the number of shares of Common Stock
                      issuable on conversion of such series shall be decreased
                      in proportion to such decrease in outstanding shares.

          (d)  Other Distributions.  In the event this Corporation shall declare
               a distribution payable in securities of other persons, evidences
               of indebtedness issued by this Corporation or other persons,
               assets (excluding cash dividends) or options or rights not
               referred to in subsection 6(c)(iii), then, in each such case for
               the purpose of this subsection 6(d), the holders of the Series B
               Preferred Stock shall be entitled to a proportionate share of any
               such distribution as though they were the holders of the number
               of shares of Common Stock of the Corporation into which their
               shares of Series B Preferred Stock are convertible as of the
               record date fixed for the determination of the holders of Common
               Stock of the Corporation entitled to receive such distribution.

          (e)  Recapitalizations.  If at any time or from time to time there
               shall be a recapitalization of the Common Stock (other than a

               elsewhere in this Section 6 or Section 4), provision shall be
               made so that the holders of the Series B Preferred Stock shall
               thereafter be entitled to receive upon conversion of the Series B
               Preferred Stock the number of shares of stock or other securities
               or property of this Corporation or otherwise, to which a holder
               of Common Stock deliverable upon conversion would have been
               entitled on such recapitalization. In any such case, appropriate
               adjustment shall be made in the application of the provisions of
               this Section 6 with respect to the rights of the holders of the
               Series B Preferred Stock after the recapitalization to the end
               that the provisions of this Section 6 (including adjustment of
               the Conversion Price then in effect and the number of shares
               purchasable upon conversion of the Series B Preferred Stock)
               shall be applicable after that event as nearly equivalent as may
               be practicable.

          (f)  No Impairment.  This Corporation will not, by amendment of its
               Certificate of Incorporation or through any reorganization,
               recapitalization, transfer of assets, consolidation, merger,
               dissolution, issue or sale of securities or any other voluntary
               action, avoid or seek to avoid the observance or performance of
               any of the terms to be observed or performed hereunder by this
               Corporation, but will at all times in good faith assist in the
               carrying out of all the provisions of this Section 6 and in the
               taking of all such action as may be necessary or appropriate in
               order to protect the Conversion Rights of the holders of the
               Series B Preferred Stock against impairment.

          (g)  No Fractional Shares and Certificate as to Adjustments.

               (i)    No fractional shares shall be issued upon conversion of
                      the Series B Preferred Stock, and the number of shares of
                      Common Stock to be issued shall be rounded to the nearest
                      whole share. Whether or not fractional shares are issuable
                      upon such conversion shall be determined on the basis of
                      the total number of shares of Series B Preferred Stock the
                      holder is at the time converting into Common Stock and the
                      number of shares of Common Stock issuable upon such
                      aggregate conversion.

               (ii)   Upon the occurrence of each adjustment or readjustment of
                      the Conversion Price of Series B Preferred Stock pursuant
                      to this Section 6, this Corporation, at its expense, shall
                      promptly compute such adjustment or readjustment in
                      accordance with the terms hereof and, through its chief
                      financial officer, certify such computation and prepare
                      and

                      furnish to each holder of Series B Preferred Stock a
                      certificate setting forth such adjustment or readjustment
                      and showing in detail the facts upon which such adjustment
                      or readjustment is based. This Corporation shall, upon the
                      written request at any time of any holder of Series B
                      Preferred Stock, furnish or cause to be furnished to such
                      holder a like certificate setting forth (A) such
                      adjustment and readjustment, (B) the Conversion Price at
                      the time in effect, and (C) the number of shares of Common
                      Stock and the amount, if any, of other property which at
                      the time would be received upon the conversion of a share
                      of Series B Preferred Stock.

          (h)  Notices of Record Date. In the event of any taking by this
               Corporation of a record of the holders of any class of securities
               for the purpose of determining the holders thereof who are
               entitled to receive any dividend (other than a cash dividend) or
               other distribution, any right to subscribe for, purchase or
               otherwise acquire any shares of stock of any class or any other
               securities or property, or to receive any other right, this
               Corporation shall mail to each holder of Series B Preferred
               Stock, at least 20 days prior to the date specified therein, a
               notice specifying the date on which any such record is to be
               taken for the purpose of such dividend, distribution or right,
               and the amount and character of such dividend, distribution or
               right.

          (i)  Reservation of Stock Issuable Upon Conversion.  This Corporation
               shall at all times reserve and keep available out of its
               authorized but unissued shares of Common Stock solely for the
               purpose of effecting the conversion of the shares of the Series B
               Preferred Stock such number of its shares of Common Stock as
               shall from time to time be sufficient to effect the conversion of
               all outstanding shares of the Series B Preferred Stock; and if at
               any time the number of authorized but unissued shares of Common
               Stock shall not be sufficient to effect the conversion of all
               then outstanding shares of the Series B Preferred Stock, this
               Corporation will take such corporate action as may, in the
               opinion of its counsel, be necessary to increase its authorized
               but unissued shares of Common Stock to such number of shares as
               shall be sufficient for such purposes.

          (j)  Notices.  Any notice required by the provisions of this Section 6
               to be given to the holders of shares of Series B Preferred Stock
               shall be deemed given if deposited in the United States mail,

require.


                                  ARTICLE TWO

                                 STOCKHOLDERS

     Section 2.01.  Annual Meeting.  The Board of Directors shall determine the
time and place of annual meetings of stockholders, at which time the
stockholders shall elect a Board of Directors and transact such other business
as may properly be brought before the meeting.

     Section 2.02.  Special Meetings.  Special Meetings of stockholders may be
called by the President or the Board of Directors, and shall be called by the
President or Secretary at the request in writing of the holders of not less than
one quarter of all the outstanding shares of the corporation entitled to vote at
the meeting.  The request shall state the purpose or purposes of the proposed
meeting.

     Section 2.03.  List of Stockholders.  At least ten days before each meeting
of stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, with the address of and the number of
shares held by each, shall be prepared by the officer or agent having charge of
the stock transfer books.  For a period of ten days prior to the meeting, the
list shall be kept either at a place within the city where the meeting is to be
held, which place shall be specified in the notice of the meeting or, if not so
specified, at the place where the meeting is to be held, and may be inspected by
any stockholder at any time during usual business hours.  The list shall be
produced and kept open at the time and place of the meeting and may be inspected
by any stockholder during the whole time of the meeting. The Board of Directors

purpose for a period of not less than ten nor more than 60 days prior to the
meeting. In the absence of any action by the Board of Directors, the record date
shall be such date as is provided by statute.

     Section 2.04.  Notice.  Written notice stating the place, day and hour of
any meeting of stockholders and, in case of a special meeting, the purpose or
purposes for which the meeting is called, shall be delivered not less than ten

mail, by or at the direction of the President, the Secretary, or the persons
calling the meeting, to each stockholder of record entitled to vote at the
meeting.

     Section 2.05.  Quorum.  The holder of a majority of the shares entitled to
vote, present in person or represented by proxy, will constitute a quorum at all
meetings of stockholders for the transaction of business except as otherwise
provided by the Certificate of Incorporation or Delaware General Corporation Law
(called "the Act" in these By-Laws).  If, however, a quorum is not present or
represented at a meeting of stockholders, a majority of the stockholders
entitled to vote who are present in person or represented by proxy will have the
power to adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum is present or represented, provided
that if the adjournment is for more than thirty days, or if after the
adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each stockholder of record entitled to
vote at the meeting.  When the meeting is reconvened, if a quorum is present or
represented, any business may be transacted which might have been transacted at
the meeting as originally notified.  The stockholders present at a duly
organized meeting may continue to transact business until adjournment,
notwithstanding the withdrawal of enough stockholders to leave less than a
quorum.

     Section 2.06.  Voting.  So long as a quorum is present, the vote of the
holders of a majority of the shares, regardless of class, having voting power
present in person or represented by proxy at a meeting shall decide any question
brought before the meeting, unless the question is one upon which, by express
provision of the Act or of the Certificate of Incorporation or of these By-Laws,
a different vote is required.  Each outstanding share, regardless of class, will
be entitled to one vote on each matter submitted to a vote at a meeting of
stockholders, except to the extent that the voting rights of the shares of a
class are limited or denied by the Certificate of Incorporation.

     Section 2.07.  Proxies.   At a meeting of the stockholders, every
stockholder having the right to vote will be entitled to vote in person, or by
proxy appointed by an instrument in writing signed by the stockholder or by his
duly authorized attorney in fact, bearing a date not more than three years prior
to the meeting unless the instrument provides for a longer period.  All proxies
shall be filed with the Secretary of the Corporation prior to or at the time of
the meeting.

     Section 2.08.  Action Without a Meeting.  Any action which may be taken at
a meeting of stockholders may be taken without a meeting, without prior notice
and without a vote, if a consent in writing, setting forth the action so taken,
is signed by all of the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such 

                                       2
<PAGE>
 
action at a meeting at which all shares entitled to vote thereon were present
and voted. Such written consents are subject to all requirements and
restrictions as stated in the Act.

by the Certificate of Incorporation or by these By-Laws directed or required to
be exercised or done by the stockholders.

     Section 3.02.  Number of Directors.  The Board of Directors shall consist
initially of three Directors and always of not less than one nor more than
fifteen Directors, none of whom need to be a stockholder or a resident of the

except as hereinafter provided, and each Director elected shall hold office
until a qualified successor is duly elected to replace him.

a Director with or without cause by the affirmative vote of a majority in number
of shares of the stockholders present in person or by proxy at the meeting and
entitled to vote for the election of the Director, if notice of the intention to
act upon such matter has been given in the notice calling the meeting.  If a
vacancy occurs in the Board of Directors caused by death, resignation,
retirement, disqualification, removal from office, or otherwise, a majority of
the Directors then in office, though less than a quorum, may choose a successor,
who shall serve the unexpired term of his predecessor in office, unless the
vacancy shall be filled by action of the stockholders.  A directorship to be
filled by reason of an increase in the number of Directors may also be filled by

Directors may be held without notice at such time and place as shall from time
to time be determined by resolution of the Board.

     Section 3.07.  Special Meetings.  Special meetings of the Board of
Directors may be called by the President on not less than 48 hours' notice to
each Director, delivered personally or by mail or telegram; special meetings
shall be called by the President or Secretary in like manner and on like notice
at the written request of three Directors.

     Section 3.08.  Quorum.  At all meetings of the Board of Directors the
presence of a majority of the number of Directors fixed by Section 3.02 of these
By-Laws will constitute a quorum for the transaction of business, and the
affirmative vote of a majority of the Directors present at any meeting at which
there is a quorum shall be the act of the Board of Directors, except as may be
otherwise specifically provided by the Act or by the Certificate of
Incorporation or by these By-Laws.  If a quorum is not present at a meeting of
Directors, the Directors present may adjourn the meeting from time to time
without notice other than announcement at the meeting until a quorum is present.

     Section 3.09.  Executive Committee.  The Board of Directors may, by
resolution passed by a majority of the whole Board, designate an executive
committee, to consist of two or more Directors.  Notwithstanding the other
provisions hereof, to the extent provided in the resolution of the Board, the
executive committee will have all of the authority of the Board of Directors in
the management of the business and affairs of the corporation, except where
action by the Board of Directors is expressly required by the Act or by the
Certificate of Incorporation, and will have power to authorize the seal of the
corporation to be affixed to all papers which may require it.  The executive
committee shall keep regular minutes of its proceedings and report the same at
the next meeting of the Board of Directors.  Any member of the executive
committee may be removed, with or without cause, by the affirmative vote of a
majority of the whole Board of Directors.  If a vacancy occurs in the executive
committee caused by death, resignation, retirement, disqualification, removal
from office, or otherwise, the vacancy shall be filled by the affirmative vote
of a majority of the whole Board of Directors.

     Section 3.10.  Other Committees.  The Board of Directors may, by resolution
passed by a majority of the whole Board, establish other committees, each
committee to consist of two or more Directors, which committees shall have such
power and authority and shall perform such functions as may be provided in such
resolution.

     Section 3.11.  Compensation of Directors.  Directors, as such, will not
receive any stated salary for their services, but, by resolution of the Board, a
fixed sum and expenses of attendance, if any, may be allowed for the attendance
at Board meetings.  A Director may, nevertheless, serve the corporation in
another capacity and receive compensation therefor.  Members of the executive
committee may, by resolution of the Board of Directors, be allowed similar
compensation for attending executive committee meetings.

     Section 3.12.  Action Without a Meeting.  Any action which may be taken at
a meeting of the Board of Directors or any committee of the Board may be taken
without a meeting if a consent in writing, setting forth the action so taken, is
signed by all of the Directors entitled to vote with

be deemed to be given at the time it is deposited postage prepaid in the United
States mails. The business transacted at a meeting need not be limited to the

stockholder or Director of the corporation under the provisions of the Act or of
the Certificate of Incorporation or of these By-Laws, a waiver thereof in
writing signed by the person entitled to notice, whether before or after the
time stated in the notice, will be the equivalent to the giving of notice.

resignation shall not be necessary to make it effective.

     Section 5.06.  Term of Office and Removal.  Each officer of the corporation

     Section 6.01.  Form of Certificates.  Certificates in such form as may be
determined by the Board of Directors, representing all shares to which he is
entitled shall be delivered to each stockholder.  Certificates shall be
consecutively numbered and shall be entered in the books of the corporation as

name, the number, class of shares, and the par value.  They shall be signed by
the Chairman of the Board, the President or a Vice President and the Secretary
or an Assistant Secretary, and may be sealed with the seal of the corporation or
a facsimile thereof.  If a certificate is countersigned by a transfer agent or
an assistant transfer agent or registered by a registrar, either of which is
other than the corporation or an employee of the corporation, the signature of
the corporation's officers may be facsimiles.  In case an officer who has signed
or whose facsimile signature has been placed on a certificate ceases to be such
officer before the certificate has been delivered by the corporation, the
certificate may nevertheless be issued and delivered as though the person who
signed the certificate or whose facsimile signature has been used thereon had
not ceased to be such officer.

     Section 6.02.  Lost, Stolen or Destroyed Certificates.  The Board of
Directors may direct that a new certificate be issued in place of any
certificate theretofore issued by the corporation alleged to have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate to be lost, stolen or destroyed.  When authorizing such
issue of a new certificate, the Board of Directors, in its discretion and as a
condition precedent to the issuance thereof, may require the owner of the lost,
stolen or destroyed certificate or his legal representative to advertise the
same in such manner as it shall require and/or to give the corporation a bond in
such form, in such sum, and with such surety as it may direct as indemnity
against any claim that may be made against the corporation with respect to the
certificate alleged to have been lost, stolen or destroyed.

     Section 6.03.  Transfer of Shares.  Shares of stock shall be transferable
on the books of the corporation by the holder thereof in person or by his duly
authorized attorney.  Upon surrender to the corporation or the transfer agent of
the corporation of a certificate representing shares duly endorsed or
accompanied by proper evidence of succession, assignment, or authority to
transfer, and compliance with any restriction relating to such transfer, it will
be the duty of the corporation or the transfer agent of the corporation, to
issue a new certificate to the person entitled thereto, cancel the old
certificate, and record the transaction upon its books.

     In the event any restriction on the transfer of shares or registration of
the transfer of shares shall be agreed to or imposed by the corporation, an
executed counterpart of the document pursuant to which such restriction exists
shall be filed with the officer of the corporation charged with the maintenance
of the stock books of the corporation and shall be kept on file at the
corporation's principal place of business.  Following such filing, each
certificate evidencing shares to which such restriction applies shall (1)
conspicuously set forth a full or summary statement of the restriction on the
face of the certificate, or (2) set forth such statement on the back of the
certificate and conspicuously refer to the same on the face of the certificate,
or (3) conspicuously state on the face or back of the certificate that such
restriction exists pursuant to a specified document and that the corporation
will furnish to the holder of the certificate, without charge, upon written
request to the corporation at its principal place of business or registered
office, a copy of the specified document.

     If one or more of the stock of any class shall, by agreement among
themselves, restrict the transfer of any shares held by them through the
granting of preferential rights of purchase or otherwise, then any party to such
agreement may file an executed counterpart of the same with the officer of the
corporation charged with the maintenance of the stock books of the corporation
or with any transfer agent or registrar designated by the corporation in respect
to the shares of such class. Following the filing of any such counterpart, each
certificate evidencing shares to which such restriction applies which shall
thereafter be issued by the corporation shall bear an appropriate notice to such
restriction as described in the preceding paragraph and no share subject to such
restriction shall be transferred until written evidence satisfactory to the
corporation of compliance by the transfer with any such restriction shall have
been filed with the corporation.

                               GENERAL PROVISIONS

     Section 8.01.  Dividends.   Dividends on outstanding shares of the
corporation, subject to the provisions of the Certificate of Incorporation, may
be declared by the Board of Directors at any regular or special meeting.
Dividends may be declared and paid in cash, in property, or in shares of the
corporation.  The Board of Directors may fix in advance a record date for the
purposes of determining stockholders entitled to receive payment of a dividend,
the record date to be not more than 60 days prior to the payment of the
dividend, or the Board of Directors may close the stock transfer books for the
same purpose for a period of not more than 60 days prior to the payment date of
the dividend.  In the absence of action by the Board of Directors, the date upon
which the Board of Directors adopts the resolution declaring the dividend will
be the record date.

     Section 8.02.  Reserves.  There may be created by resolution of the Board
of Directors out of the earned surplus of the corporation such reserve or
reserves as the Directors from time to time, in their discretion, think proper
to provide for contingencies, or to equalize dividends, or to repair or maintain
any property of the corporation, or for such other purpose as the Directors
shall deem beneficial to the corporation, and the Directors may modify or
abolish any reserve in the manner in which it was created.

     Section 8.03.  Fiscal Year.  The fiscal year of the corporation shall be
fixed by resolution of the Board of Directors.

     Section 8.04.  Seal.  The corporation may have a seal, which may be used by
causing it or a facsimile of it to be impressed or affixed or reproduced or
otherwise.  Any officer of the corporation will have authority to affix the seal
to any document requiring it.

     Section 8.05.  Indemnification.  The corporation shall indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of the
corporation)  by reason of the fact that he is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation, and, with respect
to any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful.  The termination of any action, suit or proceeding by
judgment, order, settlement or conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which he reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect 

                                       10
<PAGE>
 
to any criminal action or proceeding, had reasonable cause to believe that his
conduct was unlawful. The corporation shall indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that he is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation and except that no indemnification shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable for negligence or misconduct in the performance of
his duty to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper. The determination that an officer, director, employee or
agent, has met the applicable standard of conduct set forth hereinabove (unless
indemnification is ordered by a court) shall be made (1) by the Board of
Directors by a majority vote of a quorum consisting of directors who were not
parties to such action, suit or proceeding, or (2) by a committee of such
directors designated by majority vote of such directors, even though less than a
quorum, or (3) if there are no such directors, or if such directors so direct,
by independent legal counsel in a written opinion, or (4) by the stockholders.
Expenses incurred in defending a civil or criminal action, suit or proceeding
may be paid by the corporation in advance of the final disposition of such
action, suit or proceeding as authorized by the Board of Directors in the
specific case upon receipt of an undertaking by or on behalf of the director,
officer, employee or agent to repay such amount unless it shall ultimately be
determined that he is entitled to be indemnified by the corporation as
authorized herein. The indemnification provided hereunder shall not be deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any other by-law, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding such office, and shall
continue as to a person who has ceased to be a director, officer, employee or
agent and shall inure to the benefit of the heirs, executors and administrators
of such a person.

     Section 8.06.  Annual Statement.  The Board of Directors shall present at
each annual meeting and when called for by vote of the stockholders at special
meetings of stockholders, a full and clear statement of the business and
condition of the corporation.

     Section 9.01.  Amendments.  These By-Laws may be altered, amended, or
repealed at any meeting of the stockholders or Board of Directors at which a
quorum is present by the affirmative vote of the holders of a majority of the
voting stock of the corporation or a majority of the Directors present, but only

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
shall not disclose such customer information or network designs to its
employees, agents, subcontractors or suppliers who compete with AT&T or others;
and (3) NetSolve shall not contact any customer for whom it has provided
contract services under this Agreement until at least ninety (90) days after
termination of this Agreement, unless the customer opportunity has been
developed other than as a result of performing services hereunder.


B. Additionally, unless AT&T has given NetSolve prior written- consent, NetSolve
shall not disclose to customers, potential customers or others that NetSolve is
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
to disclose any such information, but NetSolve shall provide AT&T with prompt
notice of such requirement so that AT&T may seek an appropriate protective
order. If the required disclosure is part of a federal or state securities

provided, however, that if the required information does not include customers'
proprietary information, AT&T shall not seek an appropriate protective order
without NetSolve's consent.

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

Router Site. 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 of installed equipment.
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
(45) days after AT&T's receipt of the invoice. Any unpaid disputed amount shall

percent (1%) late charge on any undisputed amounts not paid within forty-five
(45) days after AT&T's receipt of the invoice containing such amounts.

PARAGRAPH 8 - ALTERNATE DISPUTE RESOLUTION

If a dispute arises out of or relates to this Agreement or its breach, and if
such dispute cannot be settled through good faith and negotiation of the
parties, the parties agree to submit the dispute to a sole mediator selected by
the parties or, at any time, at the option of a party, to non-binding mediation
by the American Arbitration Association ("AAA"). If not thus resolved it shall
be referred within thirty (30) days of the mediation to binding arbitration by a
sole arbitrator pursuant to the AAA Commercial Arbitration Rules. Judgment on
the arbitration award shall be made within six (6) months of selection of the
arbitrator and may be entered in any court having jurisdiction. The arbitrator
may not limit, expand or otherwise modify the terms of this Agreement, and may
not award punitive damages or damages excluded by the INDEMNITY AND LIMITATION
OF LIABILITY paragraph of this Agreement. The parties, their representatives,
other participants and the mediator and arbitrator shall hold the existence,
content and result of mediation and arbitration in confidence. The mediation and

provisions shall be void and ineffective. With AT&T's prior written consent,
which shall not be unreasonably withheld, NetSolve may subcontract installation
and maintenance responsibilities under this Agreement, but shall retain
responsibility for the subcontracted work. A list of approved sub-contractors is
provided in ATTACHMENT E hereto, "Approved NetSolve Subcontractor List". Such

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

B.  Beginning January 1, 1998, a ten-month ramp-down period will take place.  If
AT&T terminates this Agreement pursuant to Paragraph 


                               AT&T PROPRIETARY
<PAGE>
 
                                                                            -8-

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 ramp-down period, at AT&T's discretion, existing Router
Sites will be transitioned to other network management centers. The number of
Router Sites that will be transitioned will be based on a percentage of the
number of Router Sites existing at the beginning of the ramp-down 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
will be determined by AT&T, but if the actual percentage of Router Sites
supported is less than the minimum target percentage of Router Sites to be
supported, AT&T shall pay NetSolve based upon the minimum targeted percentage.
However, AT&T shall not be responsible to pay for minimum targeted percentage
shortfalls resulting from customers' terminations of Router Sites.

PARAGRAPH 25 - TIMELY PERFORMANCE

If either party has knowledge that anything prevents or threatens to prevent the
timely performance of the work under this Agreement, such party shall promptly
notify the other party's appropriate representative thereof and include all
available relevant information concerning the delay or potential delay.

PARAGRAPH 26 - USE OF INFORMATION

A. Any specifications,  drawings,  sketches, models, samples, tools, computer
or other apparatus programs or code analyses, plans, business strategies or
other technical or business information or data, written, oral or otherwise (all
hereinafter designated "Information") furnished to one party by the other under
this Agreement or in contemplation of this Agreement shall remain the disclosing
party's property; provided, however, that all customer-specific information,
whether developed or furnished by AT&T or by NetSolve, shall be deemed AT&T's
Information and shall be treated as such by the parties. All copies of such
Information in written, graphic or other tangible form shall be returned to the
disclosing party at the disclosing party's request. Unless such Information was
previously known to the receiving party free of any obligation to keep it
confidential, has been or is subsequently made public by the disclosing party,
or was independently developed by the receiving party, such Information shall be
kept confidential by the receiving party, shall be used only in performing under
this Agreement, and may not be used for other purposes except upon such terms as
may be agreed upon between NetSolve and AT&T in writing. By way of example and
not limitation, the receiving party shall:

     i.   Restrict disclosure of the Information solely to those of its
          employees, agents, subcontractors or suppliers with a need to know and
          not disclose it to third parties; and

     ii.  Advise employees, agents, subcontractors or suppliers, who receive the
          Information of the obligation of confidentiality hereunder; and

     iii. Use and require employees, agents, subcontractors or suppliers to use
          the same degree of care to protect the Information as is used by the
          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. NetSolve agrees not to disclose its
participation in this project except as otherwise provided herein.

B. Such disclosure shall not be prohiited if NetSolve is required in a judicial,
administrative or governmental proceeding to disclose any information, material,
records or files of AT&T which are obtained as a result of this Agreement, but
NetSolve shall provide AT&T with prompt notice of such requirement so that AT&T
may seek an appropriate protective order. If the required disclosure is part of
a federal or state securities filing, NetSolve shall provide AT&T with prompt
notice of such requirement; provided, however, that if the required information
does not include customers' proprietary information, AT&T shall not seek an
appropriate protective order without NetSolve's consent.

intellectual property right, is either granted or implied by the conveying of
Information to such party.

its obligations under Paragraph 30(A) and elsewhere in this Agreement shall be
$500,000; provided, however, that this limit of liability shall not apply with
respect to claims for damages to real or tangible personal property or for
bodily injury or death or with respect to the compensation set forth in

exceed the party's aggregate limit of liability and the party decides not to
increase its aggregate limit of liability to cover such claims, the other party
shall have the right to terminate this Agreement on ninety (90) days notice in

provide to AT&T in support of AT&T's CO FRAD Service offering, as requested by

Services provided under this Attachment I.

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

that the modifications requested do not require the furnishing of more material

notice, NetSolve shall not proceed with Services for any such modification until
AT&T and NetSolve Contract Representatives agree, in writing, to the appropriate

site maintenance fees for the CO FRAD CPE are not included, and shall be agreed
upon by the parties. AT&T and NetSolve will negotiate pricing in good faith if
both parties agree to provide this service.

3) For the Services described in Attachment I-3 the charges shall be as follows:

Configuration Backup and Restoral

     For the services described in Attachment I-3 for COFRAD NetFRAD
     Configuration Backup and Restoral, which is in addition to the COFRAD
     management services described above, the charges shall be as follows:

          $1,000 per COFRAD per month with the following service assumption:
          Five (5) minute backup duration per mode over a T1 line.

          .   Pricing will adjust proportionately to increased backup times, up
              to a 20 minute maximum. The pricing structure will be renegotiated
              when this threshold is crossed.
          .   Pricing will adjust proportionately to decreased backup times,
              down to a 2.5 minute minimum. Pricing will not be adjusted below
              the 2.5 minute minimum.

          For example, if actual backup time is decreased to 3.0 minutes, the
          charge per month would decrease to $600. If the actual backup time is
          increased to 10 minutes, the charge per month would be $2000.

PARAGRAPH 7 - INVOICING AND PAYMENT
NetSolve's invoices shall be rendered 1) upon completion of the Services, 2)
monthly, sent in advance, for recurring monthly charges, or 3) at other times
expressly provided for in this Attachment I, and shall be payable when the
Services have been performed to the satisfaction of AT&T. NetSolve shall mail
invoices with copies of any supporting documentation required by AT&T to: Owen

   b)  This Attachment I and any or all Orders placed hereunder may be
       terminated 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); or

       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.

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

   d)  Effective July 1, 1998, AT&T may also terminate this Attachment I and
       all Orders at its convenience at any time pursuant to the following:

       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.

               AT&T MNS AND NETSOLVE CONTRACT SERVICES AGREEMENT

                                                                 Amendment No. 5

The Contract Services Agreement effective August 1, 1995, between NetSolve,
Incorporated ("NetSolve") and AT&T Corp. ("AT&T') ("Original Contract") as
heretofore modified by Amendments Number 1, 2, 3, and 4 (collectively the
"Agreement") is further amended as follows effective as of December 1, 1997:

Previous attachments A through E are hereby deleted and replaced with Attachment
A, B, D, H, H-I and Appendices A and B.

Paragraphs 1-4 and 24 are to be deleted in the Original Contract and replaced
with the following for purposes of this Amendment No. 5 and Attachment A, B, D
and H, H-I and Appendices A and B but otherwise remain in effect, where
applicable, with respect to the other Amendments and Attachments to the
Agreement:

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, B, D, 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, B, D, H, H-1 or Appendices A and B shall be
approved and incorporated into this Amendment No. 5 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 the Director of Business Alliance. 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 No. 5 is December 1, 1997 ("Effective
Date"). The terms and conditions of this Amendment No. 5 shall apply
retroactively to the Effective Date. The term of this Amendment No. 5 is from
the Effective Date through and including the later of (i) the day ending six (6)
months after either party notifies the other in writing that it intends to
terminate this Amendment No. 5 or (ii) December 31, 1999 (the "Expiration
Date"), subject to earlier termination in accordance with this Amendment No. 5.
Following the termination of this Amendment No. 5 the twelve (12) month ramp-
down period referenced in detail in Paragraph 24 e) of this Amendment No. 5 will
commence. Any extensions of this Amendment No. 5 beyond the Expiration Date, or
continued work beyond the end of the Ramp down period, shall be pursuant to a
written Agreement addendum signed by both parties.


                                                                        12/17/97

                                                                    Page 2 of 31

                                         

At any time on or after July 1, 1999, NetSolve will have the right to refuse
NINS Managed Router Services (MRS) customer network business with respect to new
customers if AT&T notifies NetSolve that it intends to terminate this Amendment
No. 5.

PARAGRAPH 4 - PAYMENT FOR SERVICES

A.   For services performed by NetSolve under this Amendment No. 5, AT&T will
pay NetSolve a monthly recurring charge for each Router Site having a total of
three or more WAN and / or LAN connections ("Hub Site") and a monthly recurring
charge for each Router Site having a total of less than three WAN and / or LAN
connections ("Non-Hub Site"). However, if a customer's network does not have at
least one Hub Site, NetSolve will be paid the monthly Hub Site recurring charge
for one of the customer's Router Sites and the monthly Non-Hub Site recurring
charge for each of the customer's other Router Sites. The monthly recurring
charges are set forth in Table I below and applicable Discounts are set forth in
Table 2 below, both of which will be applied retroactively to all business (both
existing business as of the Effective Date and new business added after the
Effective Date) as of the Effective Date. In addition, AT&T will pay certain one
time, non-recurring charges and Time and Material (T&M) charges as set forth in
Table I below.

B.   Prices for the services in Items 1, 2, 3, 4, 5, 9, 10, and 11 of Table I
below are fixed for the term of this Amendment No. 5. Prices for Items 6, 7, 8,
and 12 may be changed by NetSolve at any time upon sixty (60) days written
notice but only if NetSolve's suppliers raise the underlying prices to NetSolve,
and the dollar amount of such increase will not exceed the net dollar increase
to NetSolve. In the event of a price change for Non-Recurring charges, orders
received prior to receipt by AT&T of the notice of the price change will be
provided at the lower of the new price or the previous price. Pricing for
equipment maintenance or other similar recurring charges which are provided by
third parties shall be applied to orders previously received based on the timing
of the price increase or decrease to NetSolve from the third party, which will
generally be on the anniversary of the start of service each year. If a price
increase exceeds 5% Netsolve shall use reasonable efforts to find substitute
suppliers. Further, AT&T may elect to utilize its own suppliers in lieu of
NetSolve's suppliers at the time an order is placed for non-recurring charges,
or thirty (30) days prior to the annual renewal of equipment maintenance
services.

   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 any Router

unemployment, social security and other payroll taxes, including contributions
when required by law. NetSolve agrees to defend, indemnify and save harmless
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");

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 


                                                                        12/17/97

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
       amount of damages, which must be capable of being ascertained with
       substantial certainty.)

For purposes of this Agreement. conduct by a party's employee or contractor
acting outside the scope of his, her or its authority will not be attributed to
that party, except to the extent such losses are covered by the party's
insurance (or, if AT&T is self-insured, to the extent such losses would have
been covered by insurance if AT&T had the same policies of insurance as NetSolve
then has).

                                                                        12/17/97

2.    Notwithstanding the foregoing, neither party's total aggregate liability
(for direct damages, Indirect Damages or otherwise) arising from or in
connection with this Agreement or any product or service (including any Service)
ordered or provided hereunder shall exceed:

    (i)  for claims for which the party has insurance coverage, the amount paid
         to the party by the insurance carrier (or, if AT&T is self-insured, the
         amount that would have been paid to ALT&T by an insurance carrier if
         AT&T had the same policies of insurance as NetSolve then has);

    (ii) for all other claims, one million dollars ($1,000,000) in total,

provided, however, that these limitations of liability shall not apply to direct
or special damages 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
       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 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) Payment for Services, Payment, Taxes, Invoicing and Payment
    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 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.)

The limitations on and disclaimers of remedies, warranties and damages set forth
in this Agreement will apply whether or not any remedy provided hereunder fails
of its essential purpose.


                                                                        12/17/97

This Attachment A to Amendment No. 5 of the Contract Services Agreement, (the
"Agreement") covers Managed Router Solutions ("MRS") that NetSolve shall provide
to AT&T in support of AT&T's Managed Network Solutions ("MNS") offering, when
requested by AT&T and as described herein. This Attachment is an integral part
of the Agreement and shall be governed by the terms of the Agreement.  In the
event of any conflict between the terms of this Attachment and the terms of the

determination of customer pricing, and in no event shall NetSolve be permitted
to review or have access to AT&T's offer pricing to end-user Customers,
strategic marketing information, or other competitively sensitive information.
NetSolve shall only receive proposals and reports that are needed to perform
quality services for AT&T in a timely manner. AT&T and NetSolve will jointly
work in defining terms and definitions for an Attachment C to be added within

successful a clear understanding of strategies and goals and an overall
governing leadership team made up of the parties is required. In order to foster
this close cooperation, NetSolve, and MNS agree to establish a Leadership Team
within a reasonable time frame following execution of this Agreement. The team
shall meet on at least a quarterly basis during the term of this Agreement. This
team shall review, coordinate and share strategic long-term planning with
respect to the services purchased by AT&T (but neither party shall be required
to divulge any proprietary information in this regard), establish principles and
policies governing the strategic relationship, set future directions, and
resolve issues presented to the team. This team shall include, at a minimum,
members from AT&T that are capable of providing functional requirements in line
with the strategies of MNS. This team shall include, at a minimum, members from
NetSolve that can understand and communicate requirements presented by AT&T
representatives to NetSolve's planning process.

PERFORMANCE METRICS AND CREDITS

Performance Metrics include the performance of NetSolve, any third party
suppliers of NetSolve and the performance of any suppliers recommended by AT&T
for which NetSolve has management responsibilities under this Attachment A. The
Performance Metrics will be used to determine any credits due AT&T by NetSolve,
subject to the adjustments set forth in the second paragraph of the section
titled "Credits for Missed DMOQs" of this Attachment A. Upon expiration of
NetSolve's equipment maintenance agreements with respect to existing customers,
AT&T may request that the renewal of such equipment maintenance services be

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 CSO
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.

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

                                                                        12/17/97

                                                                   Page 17 of 31

acceptance by AT&T; (ii) the customer requested due date; or (iii) 50 days from
receipt by NetSolve of a CSO 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

Beginning sixty days after the effective date of Amendment No. 5, 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 Items 3
and 4 of Table 1 in Paragraph 4 of Amendment No. 5. 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
6 of Table I in Paragraph 4 of Amendment No. 5.

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 Items 3 and 4 of Table 1
                               Paragraph 4 of Amendment No. 5 for all the Router
                               Sites associated with the customer.

CUSTOMER SATISFACTION METRICS

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.

        Attachment A.

For any event that precipitates this type of credit due, AT&T and NetSolve will
jointly perform an operational review to determine the factors that contributed
to the situation. Both AT&T and NetSolve will engage the proper extended team to
develop process changes to ensure these situations will be remedied for all
future activities.

The credits set forth above constitute NetSolve's sole liability, and AT&T's
sole and exclusive remedy, for any failure to meet any DMOQs or other metrics.

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.

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.

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.

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.

2.4  CREATE NETWORK MAP

NetSolve will create a network map that accompanies the pricing information in
2.3.

2.5  PROVIDE DNAE CHECKLIST

NetSolve will include the appropriate DNAE checklist with each pricing, and
design package.

3.   NETSOLVE POST SALES RESPONSIBILITIES

3.1  COMPLETE AND FORWARD CUSTOMER IMPLEMENTATION PLAN

After AT&T has received a contract for a Managed Router Service solution,
NetSolve will complete and forward a Project Summary Description to facilitate
the transfer of information to the appropriate "service factory." A copy of this
implementation plan is provided in Exhibit 2.

3.2  SALES PROCESS PERFORMANCE REPORTING

NetSolve will track and report on all the bundled Managed Router Service quoting
activity for the Commercial and Middle Markets organization completed by
NetSolve. Monthly and calendar year to date statistics will be warehoused and
reported. NetSolve will report the following metrics by service product type and
total:
     .  Number of Proposals
     .  Number of Sites
     .  Closure percentage
     .  Proposal aging histogram
     .  Interval from proposal information release to contract sign
     .  Interval from pre-qualification arrival to interview
     .  Interval from interview to proposal

3.3  UPDATE PRODUCT FEATURES AND PRICING

NetSolve will update product features and pricing within three business days of
receipt from AT&T. If AT&T should release changes on a more periodic basis than
monthly, then AT&T and NetSolve agree to negotiate an appropriate increase in
the fee per proposal.

                                                                        12/17/97

4.   COMMUNICATIONS

4.1  NETSOLVE/SALES FORCE

NetSolve will communicate initially with the field using ATTmail and Word
documents in RTF format. In the long term, the intention is to use a Web
interface to communicate to the field from a pre-qualification form and proposal
response perspective.

4.2  NETSOLVE FACTORIES

The Project Summary Description included in Exhibit 2 will be the primary method
for interfacing the quoting capability of NetSolve with other AT&T MNS
factories.

4.3  NETSOLVE/PRODUCT HOUSE

NetSolve will interface at least quarterly with the AT&T individuals and
organizations responsible for the MRS family in order to stay current with
future directions and strategy.

5.   AT&T RESPONSIBILITIES

5.1  PRE-SALES

AT&T DNAEs will determine whether the solution to be offered fits within a
standard MRS bundle prior to sending the pre-qualification form to NetSolve. If,
after NetSolve contacts the customer to develop the network design, it is
determined that the proposal will not fit into a standard bundle, then NetSolve
will contact the DNAE to explain the situation, and pass along all new
information gathered. The DNAE is then responsible for working with an AT&T DNC
to develop the design and price quote.

                                                                        12/17/97

<PAGE>
 
     1.   LEASE AGREEMENT.

     A.   Lease of Premises.  On the terms stated in this Lease, Landlord leases
the Premises to Tenant, and Tenant leases the Premises from Landlord, for the
Term beginning on the Commencement Date and ending on the Termination Date
unless extended or sooner terminated pursuant to this Lease.

     B.   Determination of Building Site.  Tenant acknowledges that while
Landlord and Tenant have agreed on the amount of approximate rentable square
feet within the Premises to be leased by Tenant hereunder, Landlord has not yet
determined whether such Premises will be located in Building 4, 5 or 6 within
the Project, as shown on Appendix A-1.  Landlord shall make such determination
and provide Tenant written notice thereof at least one hundred fifty (150) days
prior to the Commencement Date.  Upon such determination, the Building reference
in the first paragraph of this Lease, in the Schedule, and in the Commencement
Date Confirmation shall be deemed to be the numeric identification of the
Building in which the Premises are located, and Tenant and Landlord shall
execute an addendum to this Lease acknowledging such determination.

     C.   Determination of Rentable Square Feet.  Landlord and Tenant
acknowledge and agree that the Rentable Square Footage as stated in the Schedule
is an approximation and cannot be conclusively determined until after completion
of construction of the Premises and the Building.  Within sixty (60) days of the
Completion Date, the Rentable Square Footage of the Premises shall be determined
and certified in writing by Landlord's architect using the modified "BOMA"
standard, as described below.  For purposes of this determination, Rentable
Square Footage for the Premises shall be calculated by taking the sum of the
following:

          (1) (i) Square footage of Tenant's Usable Area within the first (1st)
     floor of the Building plus (ii) an "add-on factor" for Tenant's share of
     General Common Area and the Floor Common Area for the 1st floor.  The
     current estimate for the add-on-factor for the 1st floor of the Building,
     so long as Tenant shares such floor with other tenants, is 16.52% times
     Tenant's Usable Area within the 1st floor.  In the event only Tenant
     occupies such floor, the current estimate for the add-on factor for the 1st
     floor is 4.84% times Tenant's Usable Area within the 1st floor.

          (2) (i) Square footage of all Usable Area within the second (2nd)
     floor of the Building, including Floor Common Area plus (ii) an "add-on
     factor" to account for Tenant's share of General Common Area.  The current
     estimate for the add-on-factor for the 2nd floor of the Building, so long
     as such floor is occupied only by Tenant, is 4.44% times all Usable Area
     within the 2nd floor.

          (3) (i) Square footage of all Usable Area within the third (3rd) floor
     of the Building, including Floor Common Area plus (ii) an "add-on factor"
     to account for Tenant's share of General Common Area.  The current estimate
     for the add-on-factor for the 3rd floor of the Building, so long as such
     floor is occupied only by Tenant, is 4.25% times all Usable Area within the
     3rd floor.

                                       1
<PAGE>
 
Notwithstanding anything to the contrary in the foregoing, (i) the calculation
of total Rentable Square Footage for any one floor in the Building shall not be
affected by whether such floor is single-tenant or multi-tenant, (ii) the sum of
all Usable Area within the Building plus the applicable add-on factors as set
forth above shall not exceed the total Rentable Square Footage of the Building,
and (iii) in no event shall the Rentable Square Footage of the Premises exceed
one hundred five percent (105%) of the approximate square footage figure set
forth in the Plans (as defined in the Tenant Improvement Agreement attached as
Appendix C) as finally approved by Landlord and Tenant.

     D.   Definitions.

          (1) Usable Area.  "Usable Area" is computed (i) with respect to multi-
tenant floors, by measuring to the finished surface of the Premises side of the
corridor and other permanent walls, to the center of partitions that separate
the Premises from adjoining Usable Areas, and to the inside finished surface of
the dominant portion of the permanent outer building walls, and (ii) with
respect to single tenant floors, by measuring to the inside finished surface of
the dominant portion of the permanent outer building walls, excluding major
vertical penetrations of the floor.  Deductions are not made for columns and
projections necessary to the building.

          (2) General Common Areas.  "General Common Areas" are defined as all
areas intended for use by all building tenants (including building lobby,
mailroom, elevator equipment rooms, security office and fire sprinkler rooms).

          (3) Floor Common Areas.  "Floor Common Areas" are defined as all areas
for use by tenants of a single floor only, and include restrooms, janitor's
closets, mechanical, electrical, telephone rooms and building corridors,
calculated by subtracting all Usable Area on a multi-tenant floor from the
Usable Area for such floor as determined for occupancy by a single tenant.

      2.  RENT.

      A.  Types of Rent.  Tenant shall pay the following Rent in the form of a
check to Landlord at the following address:

          CarrAmerica Realty, L.P.
          t/a Riata Corporate Park
          P.O. Box ________ [to be provided by Landlord prior to Commencement
          Date]
          Atlanta, GA 30384-0566

                                       2
<PAGE>
 
or by wire transfer as follows:

          NationsBank, N.A. (South)
          ABA Number 061-000-052
          Account Number _______ [to be provided by Landlord prior to
          Commencement Date]

or at such other address or using such other wiring instructions as Landlord may
notify Tenant in writing:

          (1) Base Rent in monthly installments in advance, the first monthly
     installment payable within ten (10) days after Landlord gives Tenant the
     notice required under Section 1.B above, the second monthly installment
     payable on the first day of the second full calendar month following the
     Commencement Date, and thereafter on or before the first day of each
     succeeding calendar month of the Term in the amount set forth on the
     Schedule.  In addition, Tenant shall pay on the Commencement Date prorated
     Base Rent for any partial month in which the Commencement Date occurs, if
     the Commencement Date falls on a day other than the first (1st) day of such
     month.

          (2) Operating Cost Share Rent in an amount equal to the Tenant's
     Proportionate Share of the Operating Costs for the applicable fiscal year
     of the Lease, paid monthly in advance in an estimated amount.  Definitions
     of Operating Costs and Tenant's Proportionate Share, and the method for
     billing and payment of Operating Cost Share Rent, are set forth in Sections
     2B, 2C and 2D hereof.

          (3) Additional Rent in the amount of all costs, expenses,
     liabilities, and amounts which Tenant is required to pay under this Lease,
     excluding Base Rent and Operating Cost Share Rent, but including any
     interest for late payment of any item of Rent.

          (4) Rent as used in this Lease means Base Rent, Operating Cost Share
     Rent and Additional Rent.  Except as expressly provided herein, Tenant's
     agreement to pay Rent is an independent covenant, with no right of setoff,
     deduction or counterclaim of any kind. Notwithstanding the foregoing,
     Tenant shall be entitled to an abatement of Base Rent and Operating Cost
     Share Rent allocable to 16,475 Rentable Square Feet on the 3rd floor of the
     Building, such abatement period commencing on the Commencement Date and
     ending on the same day of the eighth (8th) calendar month thereafter,
     including any partial month in which the Commencement Date occurs and any
     partial month at the end of such abatement period (i.e., a 23.5% total 8-
     month abatement assuming Rentable Square Footage of 69,877 for the entire
     Premises).  If Tenant defaults under this Lease beyond any applicable
     period of notice and cure, any remaining rent abatement shall cease from
     the date of such default, and Tenant shall immediately pay to Landlord all
     sums previously abated hereunder.

                                       3
<PAGE>
 
      B.   Payment of Operating Cost Share Rent.

           (1) Payment of Estimated Operating Cost Share Rent.  Landlord shall
     estimate the Operating Costs of the Project by April 1 of each Fiscal Year,
     or as soon as reasonably possible thereafter.  Landlord may revise these
     estimates whenever it obtains more accurate information, such as the final
     real estate tax assessment or tax rate for the Project, but Landlord shall
     not revise the Operating Cost estimate more than once during  each Fiscal
     Year and shall provide Tenant with all calculations and documents
     supporting the appropriateness of such revisions.

           Within ten (10) days after receiving the original or revised estimate
     from Landlord, Tenant shall pay Landlord one-twelfth (1/12th) of Tenant's
     Proportionate Share of this estimate, multiplied by the number of months
     that have elapsed in the applicable fiscal year to the date of such payment
     including the current month, minus payments previously made by Tenant for
     the months elapsed.  On the first day of each month thereafter, Tenant
     shall pay Landlord one-twelfth (1/12th) of Tenant's Proportionate Share of
     this estimate, until a new estimate becomes applicable.

           (2) Correction of Operating Cost Share Rent.  Landlord shall deliver
     to Tenant a report for the previous Fiscal Year (the "Operating Cost
     Report") by April 1 of each year, or as soon as reasonably possible
     thereafter, setting forth (a) the actual Operating Costs incurred for each
     major expense category, compared to Landlord's corresponding estimates for
     such expenses, (b) the amount of Operating Cost Share Rent applicable to
     Tenant as calculated in accordance with this Lease, and (c) the amount of
     Operating Cost Share Rent paid by Tenant.  Within twenty (20) days after
     such delivery, Tenant shall pay to Landlord the amount due minus the amount
     paid.  If the amount paid exceeds the amount due, Landlord shall apply the
     excess to Tenant's payments of Operating Cost Share Rent next coming due or
     shall reimburse such amount to Tenant if such amount exceeds two (2)
     calendar months of Operating Cost Share Rent.  Upon request by Tenant,
     Landlord shall provide sufficient documentation evidencing the accuracy of
     the actual Operating Costs.

           (3) Tenant's Audit Rights.  Landlord shall maintain books and records
     reflecting the Operating Costs in accordance with sound accounting and
     management practices.  Tenant and, if Tenant elects, its certified public
     accountant shall have the right to inspect Landlord's records at Landlord's
     office upon at least seventy-two (72) hours' prior notice during normal
     business hours during the ninety (90) days following the delivery of the
     Operating Cost Report.  The results of any such inspection shall be kept
     strictly confidential by Tenant and its agents, and Tenant and, if
     applicable, its certified public accountant must agree, in their contract
     for such services, to such confidentiality restrictions and shall
     specifically agree that the results shall not be made available to any
     other tenant of the Project.  Unless Tenant sends to Landlord any written
     exception to such report within said ninety (90) day period, such report
     shall be deemed final and accepted by Tenant.  Tenant shall pay the amount
     shown on the Operating Cost Report in the manner prescribed in this Lease,
     whether or not Tenant takes any such written exception, 

                                       4
<PAGE>
 
     without any prejudice to such exception. If Tenant makes a timely
     exception, Landlord shall cause its independent certified public accountant
     to issue a final and conclusive resolution of Tenant's exception. Tenant
     shall pay the cost of such certification unless Landlord's original
     determination of annual Operating Costs overstated the amounts thereof by
     more than five percent (5%).

     C.   Definitions.

          (1) Included Operating Costs. "Operating Costs" means any expenses,
     costs and disbursements paid or incurred by Landlord in connection with the
     management [including an annual management fee, which shall not exceed four
     and one-half percent (4 1/2%) of Rent (net of the management fee) for such
     year], maintenance, operation, insurance, repair, replacement and other
     related activities in connection with any part of the Building (or the
     Project, in accordance with Section 2D(3) below) and of the personal
     property, fixtures, machinery, equipment, systems and apparatus used in
     connection therewith, including the cost of providing those services
     required to be furnished by Landlord under this Lease.  Operating Costs
     shall also include Taxes (as defined below) and the costs of any capital
     improvements which are intended to reduce Operating Costs or improve
     safety, and those made to keep the Project in compliance with governmental
     requirements applicable from time to time (collectively, "Included Capital
     Items"); provided, that the costs of any Included Capital Item shall be
     amortized by Landlord (together with an amount equal to interest at ten
     percent (10%) per annum on the unamortized portion of such capital costs,
     computed on a monthly basis) over the estimated useful life of such item,
     and such amortized costs shall be included in Operating Costs only for that
     portion of the useful life of the Included Capital Item which falls within
     the Term.

          If the Building is not fully occupied during any portion of any Fiscal
     Year, Landlord may adjust (an "Equitable Adjustment") Operating Costs to
     equal what would have been incurred by Landlord had the Building been fully
     occupied, provided that Landlord shall use commercially-reasonable
     standards in determining the extent of each such adjustment.  This
     Equitable Adjustment shall apply only to Operating Costs which are variable
     and therefore increase as occupancy of the Building increases.  Landlord
     may incorporate the Equitable Adjustment in its estimates of Operating
     Costs.

          If Landlord does not furnish any particular service whose cost would
     have constituted an Operating Cost to a tenant other than Tenant who has
     undertaken to perform such service itself, Operating Costs shall be
     increased by the amount which Landlord would have incurred if it had
     furnished the service to such tenant, which amount shall equal the product
     of such tenant's rentable square footage times Landlord's average cost per
     rentable square foot for providing such service to other Building tenants.

                                       5

               (i) franchise or income taxes imposed upon Landlord;

               (j) costs of correcting defects in construction of the Building
                   (as opposed to the cost of normal repair, maintenance and
                   replacement expected with the construction materials and
                   equipment installed in the Building in light of their
                   specifications);

               (k) legal and auditing fees which are for the benefit of Landlord
                   such as collecting delinquent rents, preparing tax returns
                   and other financial statements, and audits other than those

               (m) fines, penalties and interest; and

                                       6
<PAGE>
 
               (n) in the event Landlord contracts with a person or entity
                   which is affiliated with Landlord for a good or service, any
                   portion of the actual cost thereof which exceeds the fair
                   market cost thereof.

          (3)  Taxes. "Taxes" means any and all taxes, assessments and charges
     of any kind, general or special, ordinary or extraordinary, levied against
     the Building and adjacent portions of the Project, which Landlord shall pay
     or become obligated to pay in connection with the ownership, leasing,
     renting, management, use, occupancy, control or operation of the Project or
     of Landlord's personal property, fixtures, machinery, equipment, systems
     and apparatus used in connection therewith.  Taxes shall include real
     estate taxes, personal property taxes, sewer rents, water rents, special or
     general assessments, transit taxes, ad valorem taxes, assessments by any
     property owners association or under any deed or other restrictive
     covenants and any tax levied on the rents hereunder or the interest of
     Landlord under this Lease (the "Rent Tax").  Taxes shall also include all
     fees and other costs and expenses reasonably incurred by Landlord in
     reviewing any tax and in seeking a refund or reduction of any Taxes,
     whether or not the Landlord is ultimately successful.

          For any year, the amount to be included in Taxes (a) from taxes or
     assessments payable in installments, shall be the amount of the
     installments (with any interest) due and payable and actually paid during
     such year, and (b) from all other Taxes, shall be the amount actually paid
     in such year.  Any refund or other adjustment to any Taxes by the taxing
     authority, shall apply during the year in which the adjustment is made.

          Taxes shall not include any net federal or state income (except Rent
     Tax), capital, stock, succession, transfer, franchise, gift, estate or
     inheritance taxes.

          (4)  Lease Year.  "Lease Year" means each consecutive twelve-month
     period beginning with the Commencement Date, except that if the
     Commencement Date is not the first day of a calendar month, then the first
     Lease Year shall be the period from the Commencement Date through the final
     day of the twelve months after the first day of the following month, and
     each subsequent Lease Year shall be the twelve months following the prior
     Lease Year.

          (5)  Fiscal Year.  "Fiscal Year" means the calendar year, except that
     the first Fiscal Year and the last Fiscal Year of the Term may be a partial
     calendar year.

          (6)  Tenant's Proportionate Share. "Tenant's Proportionate Share"
     means a fraction, the numerator of which is the total Rentable Square
     Footage of the Premises, and the denominator of which is the total Rentable
     Square Footage of the Building.

                                       7
<PAGE>
 
      D.  Computation of Base Rent and Rent Adjustments.

          (1)  Prorations.  If this Lease begins on a day other than the first
     day of a month, the Base Rent and Operating Cost Share Rent shall be
     prorated for such partial month based on the actual number of days in such
     month.  If this Lease begins on a day other than the first day, or ends on
     a day other than the last day, of the Fiscal Year, Operating Cost Share
     Rent shall be prorated for the applicable Fiscal Year.

          (2)  Default Interest.  Any sum due from Tenant to Landlord not paid
     within five (5) days from the date that it is due shall bear interest from
     the date due until paid at eighteen percent (18%) per annum.

          (3)  Rent Adjustments.  If any Operating Cost paid in one Fiscal Year
     relates to more than one Fiscal Year, Landlord shall proportionately
     allocate such Operating Cost among the related Fiscal Years.  Operating
     Costs allocable to the Project as a whole (as opposed to a single building
     within the Project), including all maintenance, repair, replacement,
     insurance, Taxes and other Operating Costs associated with the parking and
     driveway areas, landscaping, project and directional signage and other
     common areas within the Project (but excluding any costs incurred by
     Landlord for the purpose of holding land within the Project for future
     development), shall be allocated among the completed buildings in the
     Project based upon the relative Rentable Square Feet within such buildings,
     and Operating Cost Share Rent shall include Tenant's Proportionate Share of
     such Operating Costs allocated to the Building.

          (4)  Miscellaneous.  So long as Tenant is in continuing default of any
     obligation under this Lease, Tenant shall not be entitled to any refund of
     any amount from Landlord until such default is cured.  If this Lease is
     terminated for any reason prior to the annual determination of Operating
     Cost Share Rent, either party shall pay the full amount due to the other in
     accordance with Sections 2B(2) and 2B(3) hereof.  Landlord may commingle
     any payments made with respect to Operating Cost Share Rent, without
     payment of interest.

     3.   PREPARATION AND CONDITION OF PREMISES; POSSESSION AND SURRENDER OF
          PREMISES.

     A.   Condition of Premises.  Except to the extent of Landlord's
construction obligations as set forth in Appendix C, Landlord is leasing the
Premises to Tenant "as is" (subject to completion of such construction), without
any obligation to alter, remodel, improve, repair or decorate any part of the
Premises.  Landlord shall cause the Premises to be completed in accordance with
the Tenant Improvement Agreement attached as Appendix C.

     B.   Tenant's Possession.  Tenant's taking possession of any portion of the
Premises shall be conclusive evidence that the Premises was in good order,
repair and condition unless Tenant notifies Landlord in writing to the contrary
within ten (10) days of such taking of 

                                       8
<PAGE>
 
possession. If Landlord authorizes Tenant to take possession of any part of the
Premises prior to the Commencement Date for purposes of doing business, all
terms of this Lease shall apply to such pre-Term possession, including Base Rent
at the rate set forth in the Schedule for months 1-36 of the Term, prorated for
any partial month.

     C.  Maintenance.  Throughout the Term, Landlord shall maintain the
structural members, roof and mechanical, electrical and other systems (including
building standard lighting) of the Premises and the Building in good condition
and repair subject to Landlord's reimbursement for the costs thereof by Tenant's
payment of Operating Cost Share Rent.  Tenant shall maintain all other portions
of the Premises in their condition as of the Completion Date, loss or damage
caused by the elements, ordinary wear, and fire and other casualty excepted.  To
the extent Tenant fails to perform this obligation, Landlord may, but need not,
restore the Premises to such condition and Tenant shall pay the cost thereof.

     4.  PROJECT SERVICES.  Landlord shall furnish services as follows:

     A.  Heating and Air Conditioning.  During the normal business hours of
7:00 a.m. to 6:00 p.m., Monday through Friday, and 8:00 a.m. to 1:00 p.m. on
Saturday, excluding New Year's Day, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day and Christmas Day, Landlord shall furnish heating and air
conditioning to provide a comfortable temperature, in Landlord's reasonable
judgment, for normal business operations, except to the extent Tenant installs
equipment which adversely affects the temperature maintained by the air
conditioning system.  If Tenant installs such equipment, Landlord or Tenant may
install supplementary air conditioning units in the Premises, and Tenant shall
pay to Landlord upon demand as Additional Rent the cost of installation,
operation and maintenance thereof.  Tenant's installation of such supplementary
units shall be subject to Section 5 hereof.

     Landlord shall furnish heating and air conditioning after business hours if
Tenant provides Landlord reasonable prior notice, and pays Landlord all then
current charges for such additional heating or air conditioning, not to exceed
one hundred fifteen percent (115%) of actual costs (including reasonable
depreciation).  Landlord shall consult with Tenant as to the most efficient
method for providing after-hours service, and shall be reasonable in determining
the method to be used.

     B.  Elevators.  Landlord shall provide passenger elevator service during
normal business hours to Tenant in common with Landlord and all other tenants,
if applicable.  Landlord shall provide limited passenger service (or full
passenger service upon Tenant's request and at Tenant's expense) at other times,
except in case of an emergency. Landlord shall install and maintain an
electronic access control system in all elevators for the use of Tenant and the
other tenants of the Building, to the extent such other tenants are located
above the 1st floor of the Building.
 
     C.  Electricity.  Landlord shall provide sufficient electricity to operate
normal office lighting and equipment, and such additional electricity as may be
provided in the Plans.  Tenant shall not install or operate in the Premises any
electrically operated equipment or other machinery,

                                       9
<PAGE>
 
other than business machines and equipment normally employed for general office
use which do not require high electricity consumption for operation, without
obtaining the prior written consent of Landlord, except as provided in the
Plans. If any or all of Tenant's equipment requires electricity consumption in
excess of that which is necessary to operate normal office equipment, or if
Tenant's extended operating hours require electricity consumption in excess of
that which is necessary to operate a normal office, such consumption (including
consumption for computer or telephone rooms and special HVAC equipment) shall be
submetered by Landlord at Tenant's expense, and Tenant shall reimburse Landlord
as Additional Rent for the cost of its submetered consumption based upon
Landlord's average cost of electricity. Such additional rent shall be in
addition to Tenant's obligations pursuant to Section 2A(2) to pay its
Proportionate Share of Operating Costs.
 
     D.  Water.  Landlord shall furnish hot and cold tap water for drinking and
toilet purposes, and for the showers, sink and dishwasher to be located in the
break room in the Premises as shown on the Plans.  Tenant shall pay Landlord for
water furnished for any other purpose as Additional Rent at rates fixed by
Landlord.  Tenant shall not permit water to be wasted.

     E.  Janitorial Service.  Landlord shall furnish janitorial service as is
generally provided for similar quality office space in Austin, Texas.

     F.  Parking.  Landlord shall provide parking areas for the Project, as
designated by Landlord from time to time, for the nonexclusive use by Tenant and
its employees and other invitees in common with Landlord and other tenants of
Project and their respective employees and other invitees, which parking areas
shall contain a total of no fewer than four (4) parking spaces (including
visitor parking spaces) for every one thousand (1,000) Rentable Square Feet
contained within the Project.  Landlord shall provide ten (10) parking spaces
within such parking areas within close proximity to the Building, which shall be
reserved for Tenant's exclusive use. Subject to the foregoing, Tenant shall have
no right to exclusive parking with respect to any parking spaces within the
Project, and Tenant shall not tow cars or otherwise enforce its parking rights
against third parties.  Tenant shall not allow its employees or other invitees
to park within any public streets adjacent to the Project.  Landlord shall not
be responsible for enforcing Tenant's parking rights against third parties and
Landlord shall have no liability to Tenant due to Tenant's inability to utilize
parking spaces within the Project; however, Landlord shall have the right, but
not the obligation, to impose reasonable rules and regulations as Landlord may
deem necessary to regulate parking within the Project, including registration of
license plate numbers for vehicles driven by Tenant's employees, issuance and
monitoring of parking tags or permits and/or designation of exclusive parking
spaces; further and not withstanding the foregoing, upon request by Tenant,
Landlord shall consult with Tenant and shall use all reasonable efforts to
resolve parking problems within the Project identified by Tenant, which may
include imposition of reasonable rules, regulations and enforcement policies in
an effort to resolve such problems, and if not resolved Tenant may allow its
employees or invitees to park within adjacent public streets if allowed under
applicable laws and any restrictive covenants.  Surface visitor parking shall be
available at no charge to Tenant or Tenant's visitors.

                                      10
<PAGE>
 
     G.  Building Security.  Landlord shall install and maintain an electronic
access control system for entry into the Building during hours other than normal
business hours as set forth above for the use of Tenant and the other tenants of
the Building.  The access system for entry into the Building and the access
system for entry into Tenant's spaces within the Building shall be coordinated.
Upon the request of Tenant and at Tenant's expense, Landlord shall provide
Tenant with copies of Landlord's log books showing records of access activity.
Landlord shall also install and maintain a fire sprinkler system for the
Building in accordance with applicable governmental requirements.

     H.  Interruption of Services.  If any of the Building equipment or
machinery ceases to function properly for any cause, Landlord shall use
reasonable diligence to repair the same promptly.  In the event such repair work
would be unreasonably disruptive to Tenant's business in the Premises, Landlord
shall perform such work during non-business hours unless Landlord must perform
such work during business hours for safety or security reasons.  Landlord's
inability to furnish, to any extent, the Project services set forth in this
Section 4, or any cessation thereof resulting from any causes, including any
entry for repairs pursuant to this Lease, and any renovation, redecoration or
rehabilitation of any area of the Project shall not render Landlord liable for
damages to either person or property or for interruption or loss to Tenant's
business, nor be construed as an eviction of Tenant, nor work an abatement of
any portion of Rent except as provided below, nor relieve Tenant from
fulfillment of any covenant or agreement hereof.  In the event that an
interruption of the Project services set forth in this Section 4 causes the
Premises to be untenantable for a period of at least three (3) consecutive
business days, monthly Rent shall be abated proportionately.

     5.  ALTERATIONS AND REPAIRS.

     A.  Landlord's Consent and Conditions.  Tenant shall not make any
improvements or alterations to the Premises (the "Work") without in each
instance submitting plans and specifications for the Work to Landlord and
obtaining Landlord's prior written consent, which consent shall not be
unreasonably withheld or delayed and shall be deemed given if not refused within
ten (10) business days after written request therefor.  Landlord will be deemed
to be acting reasonably in withholding its consent for any Work which (a)
impacts the base structural components or systems of the Building, (b) impacts
any other tenant's premises, or (c) is visible from outside the Premises.

     The following requirements shall apply to all Work:

          (1) Prior to commencement, Tenant shall furnish to Landlord building
     permits, certificates of insurance satisfactory to Landlord, and, at
     Landlord's request, security for payment of all costs.

          (2) Tenant's Work shall not unreasonably interfere with other work to
     be performed or services to be rendered in the Project.

                                      11
<PAGE>
 
          (3) The Work shall be performed in a good and workmanlike manner,
     meeting the standard for construction and quality of materials in the
     Building, and shall comply with all insurance requirements and all
     applicable governmental laws, ordinances and regulations ("Governmental
     Requirements").

          (4) Tenant shall perform all Work so as to minimize or prevent
     disruption to other tenants, and Tenant shall comply with all reasonable
     requests of Landlord in response to complaints from other tenants.

          (5) Tenant shall perform all Work in compliance with Landlord's
     "Policies, Rules and Procedures for Construction Projects" in effect at the
     time the Work is performed.

          (6) Tenant shall permit Landlord to supervise all Work.  Landlord may
     charge a supervisory fee not to exceed seven and one-half percent (7 1/2%)
     of labor, material, and all other costs of the Work (excluding the Initial
     Improvements), if Landlord's employees or contractors perform the Work.

          (7) Upon completion, Tenant shall furnish Landlord with contractor's
     affidavits and full and final statutory waivers of liens from all
     contractors and subcontractors, as-built plans and specifications, and
     receipted bills covering all labor and materials, and all other close-out
     documentation required in Landlord's "Policies, Rules and Procedures for
     Construction Projects".

          (8) Tenant shall pay for the cost of all Work.

      B.  Damage to Systems.  If any part of the mechanical, electrical or other
systems in the Premises shall be damaged as a result of the Work, Tenant shall
promptly notify Landlord, and Landlord shall repair such damage.  Landlord may
also at any reasonable time make any repairs or alterations which Landlord deems
necessary for the safety or protection of the Project, or which Landlord is
required to make by any court or pursuant to any Governmental Requirement.
Other than as set forth in Section 3(C) hereof, Tenant shall at its expense make
all other repairs necessary to keep the Premises, and Tenant's fixtures and
personal property, in good order, condition and repair; to the extent Tenant
fails to do so within ten (10) days after written demand by Landlord (or with no
demand in the case of an emergency), Landlord may make such repairs itself.  The
cost of any repairs made by Landlord on account of Tenant's default, or on
account of the mis-use or neglect by Tenant or its invitees, contractors or
agents anywhere in the Project, shall become Additional Rent payable by Tenant
on demand.

      C.  No Liens.  Tenant has no authority to cause or permit any lien or
encumbrance of any kind to affect Landlord's interest in the Project; any such
lien or encumbrance shall attach to Tenant's interest only.  If any mechanic's
lien shall be filed or claim of lien made for work or materials furnished to
Tenant, then Tenant shall at its expense within ten (10) days thereafter either
discharge or contest the lien or claim.  If Tenant contests the lien or claim,
then Tenant shall (i) within such ten (10) day period, provide Landlord adequate
security for the lien or claim 

                                      12
<PAGE>
 
by bonding in accordance with the Texas Property Code, (ii) contest the lien or
claim in good faith by appropriate proceedings that operate to stay its
enforcement, and (iii) pay promptly any final adverse judgment entered in any
such proceeding. If Tenant does not comply with these requirements, Landlord may
discharge the lien or claim, and the amount paid, as well as attorney's fees and
other expenses incurred by Landlord, shall become Additional Rent payable by
Tenant on demand.

      D.  Ownership of Improvements.  All Initial Improvements constructed under
Appendix C shall become the property of Landlord upon installation, and shall be
surrendered to Landlord with the Premises at the termination of this Lease or of
Tenant's right to possession.  All Work (not including the Initial Improvements)
as defined in this Section 5, partitions, hardware, equipment, machinery and all
other improvements and fixtures (except trade fixtures designated as such by
Tenant in any request for Landlord's approval of alterations) constructed in the
Premises by either Landlord or Tenant (i) shall become Landlord's property upon
installation without compensation to Tenant, unless Landlord consents otherwise
in writing, and (ii) shall at Landlord's option either (a) be surrendered to
Landlord with the Premises at the termination of the Lease or of Tenant's right
to possession, or (b) be removed in accordance with Section 5E below; provided
that any Work paid for by Tenant may be removed by Tenant and, in such event,
Tenant shall restore the Premises to its condition prior to the installation of
such Work.

      E.  Removal at Termination.  Upon the termination of this Lease or
Tenant's right of possession, Tenant shall remove from the Building, at Tenant's
cost, its designated trade fixtures, furniture, moveable equipment and other
personal property, any improvements which Landlord elects shall be removed by
Tenant pursuant to Section 5D, and any improvements made by Tenant to any
portion of the Building or the Project other than the Premises.  Tenant shall
repair all damage caused by the installation or removal of any of the foregoing
items.  If Tenant does not timely remove such property, then Tenant shall be
conclusively presumed to have, at Landlord's election (i) conveyed such property
to Landlord without compensation or (ii) abandoned such property, and Landlord
may dispose of or store any part thereof in any manner at Tenant's sole cost,
without waiving Landlord's right to claim from Tenant all expenses arising out
of Tenant's failure to remove the property, and without liability to Tenant or
any other person.  Landlord shall have no duty to be a bailee of any such
personal property.  If Landlord elects abandonment, Tenant shall pay to
Landlord, upon demand, any expenses incurred for removal, repair or disposition.

      6.  USE OF PREMISES.  Tenant shall use the Premises only for general
office purposes.  Tenant shall not allow any use of the Premises which will
negatively affect the cost of coverage of Landlord's insurance on the Project.
Tenant shall not allow any inflammable or explosive liquids or materials to be
kept on the Premises.  Tenant shall not allow any use of the Premises which
would cause the value or utility of any part of the Premises to diminish or
would interfere with any other tenant or with the operation of the Project by
Landlord.  Tenant shall not permit any nuisance or waste upon the Premises, or
allow any offensive noise or odor in or around the Premises.  In the event the
use by any other tenant within the Project would violate the terms of this
Section 6 with respect to such tenant's premises, Tenant shall have no
obligation 

                                      13
<PAGE>
 
to share in any increase in costs caused by such use which would otherwise be
chargeable to Tenant.

      If any governmental authority shall deem the Premises to be a "place of
public accommodation" under the Americans with Disabilities Act or any other
comparable law as a result of Tenant's use, Tenant shall either modify its use
to cause such authority to rescind its designation or be responsible for any
alterations, structural or otherwise, required to be made to the Building, the
Project or the Premises under such laws.

      7.  GOVERNMENTAL REQUIREMENTS AND BUILDING RULES.  Tenant shall comply
with all Governmental Requirements applying to its use of the Premises.  Tenant
shall also comply with all reasonable rules established for the Project from
time to time by Landlord.  The present rules and regulations are contained in
Appendix B.  Failure by another tenant to comply with the rules or failure by
Landlord to enforce them shall not relieve Tenant of its obligation to comply
with the rules or make Landlord responsible to Tenant in any way.  Landlord
shall use reasonable efforts to apply the rules and regulations uniformly with
respect to Tenant and tenants in the Project.  In the event of alterations and
repairs performed by Tenant, Tenant shall comply with the provisions of Section
5 of this Lease and also Landlord's "Policies, Rules and Regulations for
Construction Projects".

      8.  WAIVER OF CLAIMS; INDEMNIFICATION; INSURANCE.

      A.  Waiver of Claims.  To the extent permitted by law, Tenant waives any
claims it may have against Landlord or its officers, directors, employees or
agents for business interruption or damage to property sustained by Tenant as
the result of any act or omission of Landlord, to the extent typically covered
under policies of "All Risks" Property Insurance.

      To the extent permitted by law, Landlord waives any claims it may have
against Tenant or its officers, directors, employees or agents for loss of rents
or damage to property sustained by Landlord as the result of any act or omission
of Tenant, to the extent typically covered under policies of "All Risks"
Property Insurance.

      B.  Indemnification.  Tenant shall indemnify, defend and hold harmless
Landlord and its officers, directors, employees and agents against any claim by
any third party for injury to any person or damage to or loss of any property
occurring in the Project and arising from Tenant's use or occupancy of the
Premises or from any other act or omission or negligence of Tenant or any of
Tenant's employees or agents.  Tenant's obligations under this section shall
survive the termination of this Lease.

      Landlord shall indemnify, defend and hold harmless Tenant and its
officers, directors, employees and agents against any claim by any third party
for injury to any person or damage to or loss of any property occurring in the
Project and arising from any act or omission or negligence of Landlord or any of
Landlord's employees or agents. Landlord's obligations under this section shall
survive the termination of this Lease.

                                      14
<PAGE>
 
      C.  Tenant's Insurance.  Tenant shall maintain insurance as follows, with
such other terms, coverages and insurers, as Landlord shall reasonably require
from time to time:

          (1) Commercial General Liability Insurance, with (a) Contractual
     Liability including the indemnification provisions contained in this Lease,
     (b) a severability of interest endorsement, (c) limits of not less than Two
     Million Dollars ($2,000,000) combined single limit per occurrence and not
     less than Two Million Dollars ($2,000,000) in the aggregate for bodily
     injury, sickness or death, and property damage, and umbrella coverage of
     not less than Five Million Dollars ($5,000,000).

          (2) Property Insurance against "All Risks" of physical loss covering
     the replacement cost of all improvements, fixtures and personal property in
     the Premises. Tenant waives all rights of subrogation, and Tenant's
     property insurance shall include a waiver of subrogation in favor of
     Landlord and its employees and agents.

      D.  Insurance Certificates.  Tenant shall deliver to Landlord certificates

insurance at replacement cost, including loss of rents, on the Building, and
Commercial General Liability insurance policies covering the common areas of the
Building and the Project, each with such terms, coverages and conditions as are
normally carried by reasonably prudent owners of properties similar to the
Project.  With respect to property insurance, Landlord and Tenant mutually waive
all rights of subrogation, and the respective "All-Risk" coverage property
insurance policies carried by Landlord and Tenant shall contain enforceable
waiver of subrogation endorsements.

      9.  FIRE AND OTHER CASUALTY.
 
      A.  Termination.  If a fire or other casualty causes substantial damage to
the Building or the Premises, Landlord shall engage a registered architect to
certify within one (1) month of the casualty to both Landlord and Tenant the
amount of time needed to restore the Building and the Premises to tenantability,
using standard working methods.  If the time needed exceeds nine (9) months from
the beginning of the restoration, or two (2) months therefrom if the restoration
would begin during the last twelve (12) months of the Lease, then in the case of
the Premises, either Landlord or Tenant may terminate this lease, and in the
case of the Building, Landlord may terminate this Lease, by notice to the other
party within ten (10) days after the notifying party's receipt of the
architect's certificate.  The termination shall be effective thirty (30) days
from the date of the notice and Rent shall be paid by Tenant to that date, with
an abatement for any portion of the Premises which has been untenantable after
the casualty.

                                      16
<PAGE>
 
      B.  Restoration.  If a casualty causes damage to the Building or the
Premises but this Lease is not terminated for any reason, then subject to the
rights of any mortgagees or ground lessors, Landlord shall obtain the applicable
insurance proceeds and diligently restore the Building and the Premises subject
to current Governmental Requirements.  Tenant shall replace its damaged
improvements, personal property and fixtures.  Rent shall be abated on a per
diem basis during the restoration for any portion of the Premises which is
untenantable, except to the extent that Tenant's negligence caused the casualty
as established by a court having jurisdiction over the Project.

      10. EMINENT DOMAIN.  If a part of the Project is taken by eminent domain
or deed in lieu thereof which is so substantial that the Premises cannot
reasonably be used by Tenant for the operation of its business, then either
party may terminate this Lease effective as of the date of the taking.  If any
substantial portion of the Building is taken without affecting the Premises,
then Landlord may terminate this Lease as of the date of such taking.  Rent
shall abate from the date of the taking in proportion to any part of the
Premises taken.  The entire award for a taking of any kind shall be paid to
Landlord.  Tenant may pursue a separate award for its trade fixtures and moving
expenses in connection with the taking, but only if such recovery does not
reduce the award payable to Landlord.  All obligations accrued to the date of
the taking shall be performed by the party liable to perform said obligation as
set herein.

      11. RIGHTS RESERVED TO LANDLORD.  Landlord may exercise at any time any of
the following rights respecting the operation of the Project without liability
to the Tenant of any kind:

      A.  Name.  To change the name or street address of the Project or the
Building or the suite number(s) of the Premises.

      B.  Signs.  To install and maintain any signs within the Project in the
interior of the Building, to install and maintain building identification signs
on the exterior of the Building, and to approve at its sole discretion, prior to
installation, any of Tenant's signs in the Premises visible from the common
areas or the exterior of the Building.  Notwithstanding the foregoing, Landlord
agrees that Tenant shall have the right to install, at Tenant's expense (but
which may be reimbursed out of Landlord's Contribution under Appendix C), its
signage on the exterior of the Building and on a monument sign located within
the Project common areas, as well as one (1) interior sign on the second floor
front entrance to the Premises visible from the first floor lobby, all subject
to (i) Landlord's signage and architectural guidelines applicable to the Project
and (ii) Landlord's approval as to the size, location and design thereof
pursuant to the Tenant Improvement Agreement.  Tenant shall be solely
responsible for and shall obtain all sign permits and other governmental
approvals required for its signage.

      C.  Window Treatments.  To approve, at its reasonable discretion, prior to
installation, any shades, blinds, ventilators or window treatments of any kind,
as well as any lighting within the Premises that may be visible from the
exterior of the Building or any interior common area.

                                      17
<PAGE>
 
      D.  Keys.  To retain and use passkeys to enter the Premises or any door
within the Premises upon reasonable advance notice (except in case of
emergency), but only for the purpose of performing Landlord's duties or as
otherwise permitted under the Lease.  Tenant shall not alter or add any lock or
bolt.

      E.  Access.  To have access to inspect the Premises, perform its
obligations hereunder, and make repairs, alterations, additions or improvements
as permitted by this Lease, upon reasonable advance notice (except in case of
emergency).

      F.  Preparation for Reoccupancy.  To decorate, remodel, repair, alter or
otherwise prepare the Premises for reoccupancy at any time after Tenant abandons
the Premises, without relieving Tenant of any obligation to pay Rent through the
date of termination of this Lease.

      G.  Heavy Articles.  To approve the weight, size, placement and time and
manner of movement within the Building of any safe, central filing system or
other heavy article of Tenant's property.  Tenant shall move its property
entirely at its own risk.

      H.  Show Premises.  To show the Premises to prospective purchasers, non-
leasing brokers, lenders, investors, rating agencies or others at any reasonable
time after reasonable prior notice (which may be oral), and to show the Premises
to prospective tenants and leasing brokers within twelve (12) months prior to
the expiration of the Term (or such earlier period of time as may be consented
to by Tenant, in Tenant's sole discretion), provided that Landlord gives prior
notice to Tenant and does not materially interfere with Tenant's business or use
of the Premises or conduct of business therein.

      I.  [Intentionally Deleted]

      J.  Use of Lockbox.  To designate a lockbox collection agent for
collections of amounts due Landlord.  In that case, the date of payment of Rent
or other sums shall be the date of the agent's receipt of such payment or the
date of actual collection if payment is made in the form of a negotiable
instrument thereafter dishonored upon presentment.

      K.  Repairs and Alterations.  To make repairs or alterations to the
Project or the Building and in doing so transport any required material through
the Premises, to close entrances, doors, corridors, elevators and other
facilities in the Project or the Building, to open any ceiling in the Premises,
or to temporarily suspend services or use of common areas in the Project or the
Building, provided that Landlord shall use all reasonable efforts to perform
such work in a manner that does not unreasonably interfere with Tenant's use of
the Premises.  Landlord may perform any such repairs or alterations during
ordinary business hours, except that Tenant may require any work in the Premises
to be done after business hours if Tenant pays Landlord for overtime and any
other expenses incurred; provided, however, that Tenant shall not be obligated
to pay such expenses if Tenant is requiring that the work be done after business
hours in order to prevent an unreasonable interference with Tenant's use of the
Premises.  Landlord may do or permit any work on any nearby building, land,
street, alley or way.

                                      18
<PAGE>
 
      L.  Landlord's Agents.  If Tenant is in default under this Lease,
possession of Tenant's funds or negotiation of Tenant's negotiable instrument by
any of Landlord's agents shall not waive any breach by Tenant or any remedies of
Landlord under this Lease.

      M.  Building Services.  To install, use and maintain through the Premises,
pipes, conduits, wires and ducts serving the Building, provided that such
installation, use and maintenance does not unreasonably interfere with Tenant's
use of the Premises.  In the event such work will, in Tenant's reasonable
business judgment, unreasonably interfere with Tenant's use of the Premises,
Tenant may require that such work be done after business hours.

      N.  Other Actions.  To take any other action which Landlord reasonably
deems necessary or desirable in connection with the operation, maintenance or
preservation of the Project or the Building.

      12. TENANT'S DEFAULT.  Any of the following shall constitute a default by
Tenant:

      A.  Rent Default.  Tenant fails to pay any Rent when due, and, in the case
of the first two (2) such failures each Lease Year during the Term of this
Lease, this failure continues for ten (10) days after written notice from
Landlord;

      B.  Assignment/Sublease or Hazardous Substances Default.  Tenant defaults
in its obligations under Section 17 Assignment and Sublease or Section 27
Hazardous Substances;

      C.  Other Performance Default.  Tenant fails to perform any other
obligation to Landlord under this Lease, and this failure continues for fifteen
(15) days after written notice from Landlord, except that if Tenant begins to
cure its failure within the fifteen (15) day period but cannot reasonably
complete its cure within such period, then, so long as Tenant continues to
diligently attempt to cure its failure, the fifteen (15) day period shall be
extended to thirty (30) days, or such lesser period as is reasonably necessary
to complete the cure;

      D.  Credit Default.  One of the following credit defaults occurs:

          (1) Tenant commences any proceeding under any law relating to
     bankruptcy, insolvency, reorganization or relief of debts, or seeks
     appointment of a receiver, trustee, custodian or other similar official for
     the Tenant or for any substantial part of its property, or any such
     proceeding is commenced against Tenant and either remains undismissed for a
     period of sixty (60) days or results in the entry of an order for relief
     against Tenant which is not fully stayed within seven days after entry;

          (2) Tenant becomes insolvent or bankrupt, does not generally pay its
     debts as they become due, or admits in writing its inability to pay its
     debts, or makes a general assignment for the benefit of creditors;

          (3) Any third party obtains a levy or attachment under process of law
     against Tenant's leasehold interest.

                                      19
<PAGE>
 
      E.  Vacation or Abandonment Default.  Tenant vacates or abandons the
Premises.

      13. LANDLORD REMEDIES.

      A.  Termination of Lease or Possession.  If Tenant defaults and does not
cure such default within the applicable cure period, if any, Landlord may elect
by notice to Tenant either to terminate this Lease or to terminate Tenant's
possession of the Premises without terminating this Lease.  In either case,
Tenant shall immediately vacate the Premises and deliver possession to Landlord,
and Landlord may repossess the Premises and may, at Tenant's sole cost, remove
any of Tenant's signs and any of its other property, without relinquishing its
right to receive Rent or any other right against Tenant.

      B.  Lease Termination Damages.  If Landlord terminates the Lease, Tenant
shall pay to Landlord all Rent due on or before the date of termination, plus
Landlord's reasonable estimate of the aggregate Rent that would have been
payable from the date of termination through the Termination Date, reduced by
the rental value of the Premises calculated as of the date of termination for
the same period, taking into account anticipated vacancy prior to reletting,
reletting expenses and market concessions, both discounted to present value at
the rate of seven percent (7%) per annum.  If Landlord shall relet any part of
the Premises for any part of such period before such present value amount shall
have been paid by Tenant or finally determined by a court, then the amount of
Rent payable pursuant to such reletting (taking into account vacancy prior to
reletting and any reletting expenses or concessions) shall be deemed to be the
reasonable rental value for that portion of the Premises relet during the period
of the reletting.  Landlord agrees to use reasonable efforts to relet the
Premises and otherwise mitigate any damages arising out of Tenant's default.

      C.  Possession Termination Damages.  If Landlord terminates Tenant's right
to possession without terminating the Lease and Landlord takes possession of the
Premises itself, Landlord may relet any part of the Premises for such Rent, for
such time, and upon such terms as Landlord in its sole discretion shall
determine, without any obligation to do so prior to renting other vacant areas
in the Project.  Any proceeds from reletting the Premises shall first be applied
to the expenses of reletting, including redecoration, repair, alteration,
advertising, brokerage, legal, and other reasonably necessary expenses.  If the
reletting proceeds after payment of expenses are insufficient to pay the full
amount of Rent under this Lease, Tenant shall pay such deficiency to Landlord
monthly upon demand as it becomes due.  Any excess proceeds shall be retained by
Landlord.

      D.  Landlord's Remedies Cumulative.  All of Landlord's remedies under this
Lease shall be in addition to all other remedies Landlord may have at law or in
equity.  Waiver by Landlord of any breach of any obligation by Tenant shall be
effective only if it is in writing, and shall not be deemed a waiver of any
other breach, or any subsequent breach of the same obligation.  Landlord's
acceptance of payment by Tenant shall not constitute a waiver of any breach by
Tenant, and if the acceptance occurs after Landlord's notice to Tenant, or
termination of the Lease or of Tenant's right to possession, the acceptance
shall not affect such notice or termination.  Acceptance of payment by Landlord
after commencement of a legal proceeding or 

                                      20
<PAGE>
 
final judgment shall not affect such proceeding or judgment. Landlord may
advance such monies and take such other actions for Tenant's account as
reasonably may be required to cure or mitigate any default by Tenant. Tenant
shall immediately reimburse Landlord for any such advance, and such sums shall
bear interest at the default interest rate under Section 2D(2) above until paid.

      E.  Waiver of Trial by Jury.  EACH PARTY WAIVES TRIAL BY JURY IN THE EVENT
OF ANY LEGAL PROCEEDING BROUGHT BY THE OTHER IN CONNECTION WITH THIS LEASE.
EACH PARTY SHALL BRING ANY ACTION AGAINST THE OTHER IN CONNECTION WITH THIS
LEASE IN A FEDERAL OR STATE COURT LOCATED IN TRAVIS COUNTY, TEXAS, CONSENTS TO
THE JURISDICTION OF SUCH COURTS, AND WAIVES ANY RIGHT TO HAVE ANY PROCEEDING
TRANSFERRED FROM SUCH COURTS ON THE GROUND OF IMPROPER VENUE OR INCONVENIENT
FORUM.

      F.  Litigation Costs.  The prevailing party in any dispute between
Landlord and Tenant concerning this Lease shall be entitled to recover its
reasonable attorneys' fees and other costs in enforcing this Lease, whether or
not suit is filed, from the non-prevailing party.

      14. SURRENDER.  Upon termination of this Lease or Tenant's right to
possession, Tenant shall return the Premises to Landlord broom clean and in good
order and condition, ordinary wear and casualty damage excepted.  If Landlord
requires Tenant to remove any alterations as permitted under Section 5 hereof,
then Tenant shall remove the alterations in a good and workmanlike manner and
restore the Premises to its condition prior to their installation.

      15. HOLDOVER.  Tenant shall have no right to holdover possession of the
Premises after the expiration or termination of this Lease without Landlord's
prior written consent, which Landlord may withhold in its sole and absolute
discretion.  If, however, Tenant retains possession of any part of the Premises
after the Term, Tenant shall become a month-to-month tenant for the entire
Premises upon all of the terms of this Lease as might be applicable to such
month-to-month tenancy, except that Tenant shall pay all of Base Rent and
Operating Cost Share Rent at one hundred fifty percent (150%) of the rate in
effect immediately prior to such holdover, computed on a monthly basis for each
full or partial month Tenant remains in possession.  Tenant shall also pay
Landlord all of Landlord's direct and, if Tenant fails to surrender the Premises
within thirty (30) days of written notice, Landlord's consequential damages.  No
acceptance of Rent or other payments by Landlord under these holdover provisions
shall operate as a waiver of Landlord's right to regain possession upon demand,
or any other of Landlord's remedies.

      16. SUBORDINATION TO GROUND LEASES AND MORTGAGES.

      A.  Subordination.  This Lease shall be subordinate to any present or
future ground lease or mortgage respecting the Building or any other portion of
the Project, and any amendments to such ground lease or mortgage, at the
election of the ground lessor or mortgagee as the case may be, effected by
notice to Tenant in the manner provided in this Lease.  The subordination shall
be effective upon such notice, but at the request of Landlord or ground lessor
or mortgagee, 

                                      21
<PAGE>
 
Tenant shall within fifteen (15) days of the request, execute and deliver to the
requesting party any reasonable documents provided to evidence the
subordination.

      B.  Termination of Ground Lease or Foreclosure of Mortgage.  If any ground
lease is terminated or mortgage foreclosed or deed in lieu of foreclosure given
and the ground lessor, mortgagee, or purchaser at a foreclosure sale shall
thereby become the owner of the Building, then, at the option of such ground
lessor, mortgagee or purchaser and conditioned upon its agreement not to disturb
Tenant's quiet possession of the Premises so long as Tenant is not in default
hereunder, Tenant shall attorn to such ground lessor or mortgagee or purchaser
without any deduction or setoff by Tenant, and this Lease shall continue in
effect as a direct lease between Tenant and such ground lessor, mortgagee or
purchaser.  The ground lessor or mortgagee or purchaser shall be liable as
Landlord only during the time such ground lessor or mortgagee or purchaser is
the owner of the Building.  At the request of Landlord, ground lessor or
mortgagee, Tenant shall execute and deliver within ten (10) days of the request
any document furnished by the requesting party to evidence Tenant's agreement to
attorn and the ground lessor or mortgagee's agreement not to disturb Tenant's
quiet possession, so long as Tenant is not in default hereunder.
 
      C.  Security Deposit.  Any ground lessor or mortgagee shall be responsible
for the return of any security deposit by Tenant only to the extent the security
deposit is received by such ground lessor or mortgagee.  Tenant shall not be
required to place any additional security deposit with such ground lessor or
mortgagee beyond that already then required and in place under this Lease.

      D.  Notice and Right to Cure.  The Building is subject to any ground lease
and mortgage identified with name and address of ground lessor or mortgagee in
Appendix D to this Lease (as the same may be amended from time to time by
written notice to Tenant).  Tenant agrees to send by registered or certified
mail to any ground lessor or mortgagee identified either in such Appendix or in
any later notice from Landlord to Tenant a copy of any notice of default sent by
Tenant to Landlord.  If Landlord fails to cure such default within the required
time period under this Lease, but ground lessor or mortgagee begins to cure
within ten (10) days after such period and proceeds diligently to complete such
cure, then ground lessor or mortgagee shall have such additional time as is
reasonably necessary to complete such cure, including any time necessary to
obtain possession if possession is necessary to cure, and Tenant shall not begin
to enforce its remedies so long as the cure is being diligently pursued.

      E.  Definitions.  As used in this Section 16, "mortgage" shall include
"deed of trust" and "mortgagee" shall include "beneficiary" under such deed of
trust, "mortgagee" shall include the mortgagee of any ground lessee, and "ground
lessor", "mortgagee", and "purchaser at a foreclosure sale" shall include, in
each case, all of its successors and assigns, however remote.

                                      22

      17. ASSIGNMENT AND SUBLEASE.

      A.  In General.  Tenant shall not, without the prior consent of Landlord
in each case, (i) make or allow any assignment or transfer, by operation of law
or otherwise, of any part of Tenant's interest in this Lease, (ii) grant or
allow any lien or encumbrance, by operation of law or otherwise, upon any part
of Tenant's interest in this Lease, (iii) sublet any part of the Premises, or
(iv) permit anyone other than Tenant and its employees, resellers and supplier
partners to occupy any part of the Premises, provided that such resellers and
supplier partners shall not be separately identified to the outside public.
Tenant shall remain primarily liable for all of its obligations under this
Lease, notwithstanding any assignment or transfer.  No consent granted by
Landlord shall be deemed to be a consent to any subsequent assignment or
transfer, lien or encumbrance, sublease or occupancy.  Tenant shall pay all of
Landlord's reasonable attorneys' fees and other expenses incurred in connection
with any consent requested by Tenant or in reviewing any proposed assignment or
subletting.  Any assignment or transfer, grant of lien or encumbrance, or
sublease or occupancy without Landlord's prior written consent shall be void. If
Tenant shall assign this Lease other than as permitted herein or sublet the
Premises in its entirety, any rights of Tenant to renew this Lease, extend the
Term or to lease additional space in the Project shall be extinguished thereby
and will not be transferred to the assignee or subtenant, all such rights being
personal to the Tenant named herein.  The sale, conveyance or issuance of
capital stock of Tenant shall not constitute an assignment of this Lease.

      B.  Landlord's Consent.  Landlord will not unreasonably withhold its
consent to any proposed assignment or subletting.  It shall be reasonable for
Landlord to withhold its consent to any assignment or sublease if (i) Tenant is
in default under this Lease, (ii) the proposed assignee or sublessee is a tenant
in the Project or an affiliate of such a tenant or a party that Landlord has
identified as a prospective tenant in the Project, (iii) the financial
responsibility and nature of business of the proposed assignee or subtenant are
not all reasonably satisfactory to Landlord, (iv) in the reasonable judgment of
Landlord the purpose for which the assignee or subtenant intends to use the
Premises (or a portion thereof) is not in keeping with Landlord's standards for
the Project or the Building or are in violation of the terms of this Lease or
any other leases in the Project, (v) the proposed assignee or subtenant is a
government entity, or (vi) the proposed assignment (but not a sublease) is for
less than the entire Premises or for less than the remaining Term of the Lease.
The foregoing shall not exclude any other reasonable basis for Landlord to
withhold its consent.

      C.  Procedure.  Tenant shall notify Landlord of any proposed assignment or
sublease at least thirty (30) days prior to its proposed effective date.  The
notice shall include the name and address of the proposed assignee or subtenant,
its corporate affiliates in the case of a corporation and its partners in a case
of a partnership, an execution copy of the proposed assignment or sublease, and
sufficient information to permit Landlord to determine the financial
responsibility of the proposed assignee or subtenant.  As a condition to any
effective assignment of this Lease, the assignee shall execute and deliver in
form satisfactory to Landlord at least fifteen (15) days prior to the effective
date of the assignment, an assumption of all of the obligations of Tenant under
this Lease.  As a condition to any effective sublease, subtenant shall execute
and deliver in form satisfactory to Landlord prior to the effective date of the
sublease, an agreement to comply 

                                      23
<PAGE>
 
with all of Tenant's obligations under this Lease, and at Landlord's option, an
agreement (except for the economic obligations which subtenant will undertake
directly to Tenant) to attorn to Landlord under the terms of the sublease in the
event this Lease terminates before the sublease expires.

      D.  Excess Payments.  If Tenant shall assign this Lease or sublet any part
of the Premises for consideration in excess of the pro-rata portion of Rent
applicable to the space subject to the assignment or sublet, then Tenant shall
pay to Landlord as Additional Rent 50% of any such excess immediately upon
receipt.

      E.  Recapture.  Landlord may, by giving written notice to Tenant within
thirty (30) days after receipt of Tenant's notice of assignment or subletting,
terminate this Lease with respect to the space described in Tenant's notice, as
of the effective date of the proposed assignment or sublease and all obligations
under this Lease as to such space shall expire except as to any obligations that
expressly survive any termination of this Lease.

      18. CONVEYANCE BY LANDLORD.  If Landlord shall at any time transfer its
interest in the Building or this Lease, Landlord shall be released of any
obligations occurring after such transfer provided any transferee of Landlord
assumes in writing all of Landlord's obligations under this Lease, including the
return of any security deposit delivered to such transferee, except that
Landlord shall not be released of the obligation to return to Tenant any
security deposit not delivered to its transferee.  Tenant shall look solely to
Landlord's successors for performance of such obligations.  This Lease shall not
be affected by any such transfer.

      19. ESTOPPEL CERTIFICATE; FINANCIAL STATEMENTS.  Tenant shall, within ten
(10) days of receiving  a request from Landlord, execute, and deliver to
Landlord or its designee (i) financial statements, including an income statement
and balance sheet, for Tenant's most recently ended fiscal year, provided that
any recipient thereof executes a reasonable non-disclosure agreement so long as
Tenant's stock is privately held, and (ii) a certificate acknowledged in
recordable form stating, subject to a specific statement of any applicable
exceptions, that the Lease as amended to date is in full force and effect, that
the Tenant is paying Rent and other charges on a current basis, and that to the
best of the knowledge of Tenant, Landlord has committed no uncured defaults and
Tenant has no offsets or claims.  Tenant may also be required to state the date
of commencement of payment of Rent, the Commencement Date, the Termination Date,
the Base Rent, the current Operating Cost Share Rent estimate, the status of any
improvements required to be completed by Landlord, the amount of any security
deposit, and such other matters as may be reasonably requested.  Failure to
deliver such statement after a second 5-day notice shall be conclusive evidence
against Tenant that this Lease, with any amendments identified by Landlord, is
in full force and effect, that there are no uncured defaults by Landlord, that
not more than one month's Rent has been paid in advance, that Tenant has not
paid any security deposit in excess of that set forth herein, and that Tenant
has no claims or offsets against Landlord.

                                      24
<PAGE>
 
      20. SECURITY DEPOSIT.  Tenant shall deposit with Landlord within ten (10)
days after Landlord gives Tenant the notice required under Section 1.B. hereof
security (the "Security Deposit") for the performance of all of its obligations
in the amount set forth on the Schedule, which security shall be in the form of
an unconditional and irrevocable letter of credit (the "Letter of Credit") (i)
in form and substance reasonably satisfactory to Landlord, (ii) naming Landlord
or its assignees as beneficiary, (iii) expressly allowing Landlord to draw upon
it at any time from time to time by delivering to the issuer notice that
Landlord is entitled to draw thereunder, (iv) drawable on an FDIC-insured
financial institution reasonably satisfactory to Landlord, and (v) redeemable in
the state of Landlord's choice.  If Tenant does not provide Landlord with a
substitute Letter of Credit complying with all of the requirements hereof at
least ten (10) days before the stated expiration date of the current Letter of
Credit, then Landlord shall have the right to draw upon the current Letter of
Credit and hold the funds drawn as the Security Deposit until a substitute
Letter of Credit is provided.  If Tenant defaults under this Lease (after lapse
of any applicable notice and cure period), Landlord may use any part of the
Security Deposit to pay or perform any obligation of Tenant under this Lease as
permitted hereunder, or to compensate Landlord for any loss or damage resulting
from any such default as permitted hereunder.  To the extent any portion of the
Security Deposit is used, Tenant shall within five (5) days after demand from
Landlord reinstate the Security Deposit to its full amount.  Landlord shall
return the Letter of Credit to Tenant upon the earlier to occur of (i) thirty
(30) days after the end of the Term, provided Tenant has performed all of its
obligations under this Lease and returned the Premises to Landlord at the end of
the Term or (ii) Tenant's delivery to Landlord of audited financial statements
showing that Tenant has earned a net operating profit for four (4) consecutive
calendar quarters following the Commencement Date, provided Tenant deposits in
cash with Landlord, prior to such return, a replacement Security Deposit equal
to $115,000.00.  The Security Deposit shall not serve as an advance payment of
Rent or a measure of Landlord's damages for any default under this Lease.  If
Landlord transfers its interest in the Project or this Lease, Landlord may
transfer the Security Deposit to its transferee.  Upon such transfer and
assumption by the transferee of the obligation to return the Security Deposit,
Landlord shall have no further obligation to return the Security Deposit to
Tenant, and Tenant's right to the return of the Security Deposit shall apply
solely against Landlord's transferee.

      21. FORCE MAJEURE.  Landlord shall not be in default under this Lease to
the extent Landlord is unable to perform any of its obligations on account of
any strike or labor problem, energy shortage, governmental pre-emption or
prescription, national emergency, or any other cause of any kind beyond the
reasonable control of Landlord ("Force Majeure").

      22. NOTICES.  All notices, consents, approvals and similar communications
to be given by one party to the other under this Lease, shall be given in

indemnify and defend Landlord against any claims by any other broker or third
party for any payment of any kind in connection with this Lease. Landlord shall

Tenant's Real Estate Broker in connection with this Lease pursuant to separate
written agreements.  Such separate agreement between Landlord and Tenant's Real
Estate Broker is dated September 4, 1997, and under certain circumstances may
obligate Landlord to pay commissions in connection with expansion or renewal

late charge equal to the greater of five percent (5%) of the amount of such
payment or $250.  In addition, interest shall be paid by Tenant to Landlord on
any late payments of Rent from the date due until paid at the rate provided in
Section 2D(2).  Such late charge and interest shall constitute Additional Rent
due and payable by Tenant to Landlord upon the date of payment of the delinquent
payment referenced above.

      Y.  Usury Savings.  All agreements between Landlord and Tenant, whether
now existing or hereafter arising and whether written or oral, are hereby

contracted for, charged or received by Landlord for the use, forbearance or
retention of money hereunder or otherwise exceed the maximum amount which
Landlord is legally entitled to contract for, charge or collect under the
applicable state or federal law.  If, from any circumstance whatsoever,
fulfillment of any provision hereof at the time performance of such provision
shall be due shall involve transcending the limit of validity prescribed by law,
then the obligation to be fulfilled shall be automatically reduced to the limit
of such validity, and if from any such circumstance Landlord shall ever receive
as interest or otherwise an amount in excess of the maximum that can be legally
collected, then such amount which would be excessive interest shall be applied
to the reduction of rent hereunder, and if such amount which would be excessive
interest exceeds such rent, then such additional amount shall be refunded to
Tenant.

      Z.  Waiver of Warranties.  TENANT HEREBY WAIVES THE BENEFIT OF ALL
WARRANTIES, EXPRESSED OR IMPLIED, WITH RESPECT TO THE PREMISES INCLUDING,
WITHOUT LIMITATION, ANY IMPLIED WARRANTY THAT THE PREMISES ARE SUITABLE FOR ANY

      AA. Effective Date.  Any reference contained in this Lease to the
"Effective Date," "date hereof" or similar terms shall mean the last date on
which any party required to execute or initial this Lease does so, and such date
shall be set forth in the first paragraph of this Lease where indicated.

      BB. Special Provisions.  Certain special provisions of this Lease are
attached hereto as Appendix F and incorporated herein by this reference.

      26. UNRELATED BUSINESS INCOME.  If Landlord is advised by its counsel at
any time that any part of the payments by Tenant to Landlord under this Lease
may be characterized as unrelated business income under the United States
Internal Revenue Code and its regulations, then Tenant shall enter into any
amendment proposed by Landlord to avoid such income, so long as the amendment
does not require Tenant to make more payments or accept fewer services from
Landlord, than this Lease provides.

      27. HAZARDOUS SUBSTANCES.  Tenant shall not cause or permit any Hazardous
Substances to be brought upon, produced, stored, used, discharged or disposed of
in or near the Project unless Landlord has consented to such storage or use in
its sole discretion; provided, however, outdoor fuel storage for Tenant's
generator and indoor storage of batteries for Tenant's uninterrupted power
supply systems shall be permitted so long as such materials are used, stored,
handled and disposed of in compliance with Environmental Laws (as defined
below).  "Hazardous Substances" include those hazardous substances described in
the Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended, 42 U.S.C. Section 9601 et seq., the Resource Conservation and
Recovery Act, as amended, 42 U.S.C. Section 6901 et seq., any other applicable
federal, state or local law, and the regulations adopted under these laws
(collectively, "Environmental Laws").  If any lender or governmental agency
shall require testing for Hazardous Substances in the Premises, Tenant shall pay
for such testing.  Tenant agrees to indemnify and hold Landlord harmless from
all claims, demands, actions, liabilities, costs, expenses, damages and
obligations of any nature arising from the contamination of the Project with
Hazardous Substances as a result of or arising out of the use or occupancy of
the Premises by Tenant.  The foregoing indemnification shall survive the
termination or expiration of this Lease.

      28. LANDLORD'S DEFAULT; EXCULPATION.  In the event of any default by
Landlord, Tenant will give Landlord written notice specifying such default with
particularity, and Landlord shall there upon have thirty (30) days (or such
longer period as may be required in the exercise of due diligence) in which to
cure any such default.  Unless and until Landlord fails to cure any default
after such notice and cure period, Tenant shall not have any remedy or cause of
action by reason thereof.  In event of any default by Landlord continuing after
such notice and 

                                      30
<PAGE>
 
cure period, Tenant's exclusive remedy shall be an action for
damages.  Landlord shall have no personal liability under this Lease; its
liability shall be limited to its interest in the Building, and shall not extend
to any other property or assets of the Landlord.  In no event shall any officer,
director, employee, agent, shareholder, partner, member or beneficiary of
Landlord be personally liable for any of Landlord's obligations hereunder, and
in no event shall any officer, director, employee, agent, shareholder, partner,
member or beneficiary of Tenant be personally liable for any of Tenant's
obligations hereunder.

      29. LANDLORD'S LIEN.  LANDLORD SHALL HAVE AND TENANT HEREBY GRANTS TO

WITHOUT THE CONSENT OF LANDLORD UNTIL ALL ARREARAGES IN RENT AS WELL AS ANY AND
ALL OTHER SUMS OF MONEY THEN DUE TO LANDLORD HEREUNDER SHALL FIRST HAVE BEEN
PAID AND DISCHARGED.  PRODUCTS OF COLLATERAL ARE ALSO COVERED.  IN THE EVENT OF
A DEFAULT UNDER THIS LEASE, LANDLORD SHALL HAVE, IN ADDITION TO ANY OTHER
REMEDIES PROVIDED HEREIN OR BY LAW, ALL RIGHTS AND REMEDIES UNDER THE UNIFORM
COMMERCIAL CODE, INCLUDING WITHOUT LIMITATION THE RIGHT TO SELL THE PROPERTY
DESCRIBED IN THIS PARAGRAPH AT PUBLIC OR PRIVATE SALE UPON FIVE (5) DAYS NOTICE
TO TENANT.  TENANT HEREBY AGREES TO EXECUTE SUCH OTHER INSTRUMENTS REASONABLY
REQUIRED TO PERFECT THE SECURITY INTEREST HEREBY CREATED.  ANY STATUTORY LIEN
FOR RENT IS NOT HEREBY WAIVED, THE EXPRESS CONTRACTUAL LIEN HEREIN GRANTED BEING
IN ADDITION AND SUPPLEMENTARY THERETO.  LANDLORD AND TENANT AGREE THAT THIS
LEASE AND SECURITY AGREEMENT SERVES AS A FINANCING STATEMENT AND THAT A COPY OR
PHOTOGRAPHIC OR OTHER REPRODUCTION OF THIS PORTION OF THIS LEASE MAY BE FILED OF
RECORD BY LANDLORD AND HAVE THE SAME FORCE AND EFFECT AS THE ORIGINAL.  THIS
SECURITY AGREEMENT AND FINANCING STATEMENT ALSO COVERS FIXTURES LOCATED AT THE
PREMISES, AND MAY BE FILED FOR RECORD IN THE REAL ESTATE RECORDS. TENANT
WARRANTS THAT THE COLLATERAL SUBJECT TO THE SECURITY INTEREST GRANTED HEREIN IS
NOT PURCHASED OR USED BY TENANT FOR PERSONAL, FAMILY OR HOUSEHOLD PURPOSES.
NOTWITHSTANDING THE FOREGOING, LANDLORD SHALL, UPON REQUEST BY TENANT,
SUBORDINATE ITS SECURITY INTEREST AS AFORESAID TO ANY LINE OF CREDIT LENDER
AND/OR ANY EQUIPMENT LESSOR DESIGNATED BY TENANT, PURSUANT TO A SUBORDINATION
AGREEMENT REASONABLY ACCEPTABLE TO LANDLORD.

                             RULES AND REGULATIONS

the glass of any window, door, partition or wall which may, in Landlord's
reasonable judgment, appear unsightly from outside of the Building.

     2.   The Building directory shall be available to Tenant solely to display
names and their location in the Building, which display shall be as directed by
Landlord.

     3.   The sidewalks, halls, passages, exits, entrances, elevators and
stairways shall not be obstructed by Tenant or used by Tenant for any purposes
other than for ingress to and egress from the Premises.  Tenant shall lend its
full cooperation to keep such areas free from all obstruction and in a clean and
sightly condition and shall move all supplies, furniture and equipment as soon
as received directly to the Premises and move all such items and waste being
taken from the Premises (other than waste customarily removed by employees of
the Building) directly to the shipping platform at or about the time arranged
for removal therefrom.  The halls, passages, exits, entrances, elevators,
stairways, balconies and roof are not for the use of the general public and
Landlord shall, in all cases, retain the right to control and prevent access
thereto by all persons whose presence in the judgment of Landlord, reasonably
exercised, shall be prejudicial to the safety, character, reputation and
interests of the Building.  Neither Tenant nor any employee or invitee of Tenant
shall go upon the roof of the Building.

     4.   The toilet rooms, urinals, wash bowls and other apparatuses shall not
be used for any purposes other than that for which they were constructed, and no

extent caused by Tenant or its employees or invitees, the expense of any
breakage, stoppage or damage resulting from the violation of this rule shall be
borne by Tenant.

     5.   Tenant shall not cause any unnecessary janitorial labor or services by
reason of Tenant's carelessness or indifference in the preservation of good
order and cleanliness.

conditioning apparatus, or carry on any mechanical business without the prior
written consent of Landlord, which shall not be unreasonably withheld; use the

Landlord therefor. Tenant shall not make, or cause to be made, any such keys,
shall order all such keys solely from Landlord and shall pay Landlord $10.00
each for any keys in addition to the two sets of keys originally furnished by
Landlord for each lock, which dollar amount shall be increased only to pass
through any increases from the supplier of such additional keys.

     10.  Tenant shall not install linoleum, tile, carpet or other floor
covering so that the same shall be affixed to the floor of the Premises in any
manner except as approved by Landlord.

     11.  No furniture, packages, supplies, equipment or merchandise will be
received in the Project or carried up or down in any elevator, except in such
elevator as shall be designated by Landlord, and with such padding or other
precautions as may be required by Landlord.  Tenant shall not take or permit to
be taken in or out of other entrances of the Building any item normally taken in

Building at the end of the day, provided that Landlord hereby acknowledges that
Tenant may be operating its business, including the operation of computers, 24
hours a day within the Premises.

     13.  Without the prior written consent of Landlord, which shall not be
unreasonably withheld, Tenant shall not use the name of the Building or the

Tenant, except Tenant may use the address of the Building as the address of its
business.

     14.  Tenant shall cooperate fully with Landlord to assure the most
effective operation of the Premises' or the Building's heating and air
conditioning, and shall refrain from attempting to adjust any controls, other

                                  APPENDIX C

                         TENANT IMPROVEMENT AGREEMENT

     1.   INITIAL IMPROVEMENTS.  Landlord shall cause to be performed the
improvements (the "Initial Improvements") in the Premises in accordance with
plans and specifications approved by Tenant and Landlord (the "Plans"), which
approvals shall not be unreasonably withheld.  The Initial Improvements shall be
performed at the Tenant's cost, subject to the Landlord's Contribution
(hereinafter defined).  The Initial Improvements shall include Tenant's building
and common area signage.

     Landlord shall cause the Plans to be prepared, at Landlord's cost as part
of Landlord's Contribution, by a registered professional architect, and
mechanical and electrical engineer(s). Within forty-five (45) days after the
date of the Lease, Landlord shall furnish the initial draft of the Plans to
Tenant for Tenant's review and approval.  Tenant shall within two (2) weeks
after receipt either provide comments to such Plans or approve the same.  Tenant
shall be deemed to have approved such Plans if it does not provide comments on
such Plans within such 2-week period.  If Tenant provides Landlord with comments
to the initial draft of the Plans, Landlord shall provide revised Plans to
Tenant incorporating Tenant's comments within one week after receipt of Tenant's
comments.  Tenant shall within one week after receipt then either provide
comments to such revised Plans or approve such Plans.  Tenant shall be deemed to
have approved such revised Plans if Tenant does not provide comments on such
Plans within such 1-week period. The process described above shall be repeated,
if necessary, until the Plans have been finally approved by Tenant.

     Landlord, with consultation of Tenant, shall select a contractor to perform
the construction of the Initial Improvements.  Landlord shall use commercially
reasonable efforts to cause the Initial Improvements to be substantially
completed, except for minor "Punch List" items, on or before the Commencement
Date specified in the Schedule to the Lease, subject to Tenant Delay (as defined
in Section 4 hereof) and Force Majeure.

     Landlord, or an agent of Landlord, shall provide project management
services in connection with the construction of the Initial Improvements and the
Change Orders (hereinafter defined).  Such project management services shall be
performed, at Tenant's cost, for a fee of two percent (2%) of all costs related
to the preparation of the Plans and the construction of the Initial Improvements
and the Change Orders.

     2.   CHANGE ORDERS.  If, prior to the Commencement Date, Tenant shall
require improvements or changes (individually or collectively, "Change Orders")
to the Premises in addition to, revision of, or substitution for the Initial
Improvements, Tenant shall deliver to Landlord for its approval plans and
specifications for such Change Orders.  If Landlord does not approve of the
plans for Change Orders, Landlord shall advise Tenant of the revisions required
within five (5) business days of Landlord's receipt of such plans.  Tenant shall
revise and redeliver the plans and specifications to Landlord within five (5)
business days of Landlord's advice or Tenant shall be deemed to have abandoned
its request for such Change Orders.  Tenant 
<PAGE>
 
shall pay for all preparations and revisions of plans and specifications with
respect to Change Orders, and the construction of all Change Orders, subject to
Landlord's Contribution.

     3.   LANDLORD'S CONTRIBUTION.  Landlord shall contribute an amount up to
$19.00 per square foot of Usable Area within the Premises ("Landlord's
Contribution") toward the costs incurred for the Initial Improvements and Change
Orders, including costs for architectural and engineering services and
permitting and construction fees.  Landlord has no obligation to pay for costs
of the Initial Improvements or Change Orders in excess of Landlord's
Contribution.  If the cost of the Initial Improvements and/or Change Orders
exceeds the Landlord's Contribution, Tenant shall pay such overage to Landlord
fifty percent (50%) upon commencement of construction of the Initial
Improvements and/or Change Orders and fifty percent (50%) upon the later of
receipt of documentation of the final costs and the Commencement Date.

     4.   COMMENCEMENT DATE DELAY.  Commencement Date shall be delayed until the
Initial Improvements have been substantially completed (the "Completion Date"),
except to the extent that the delay shall be caused by any one or more of the
following (a "Tenant Delay"):

          (a) Tenant's request for Change Orders whether or not any such Change
Orders are actually performed; or
 
          (b) Contractor's performance of any Change Orders; or

          (c) Tenant's request for materials, finishes or installations
requiring unusually long lead times; or

          (d) Tenant's delay in reviewing, revising or approving plans and
specifications beyond the periods set forth herein; or

          (e) Tenant's delay in providing information critical to the normal
progression of the project.  Tenant shall provide such information as soon as
reasonably possible, but in no event longer than one week after receipt of such
request for information from the Landlord; or

          (f) Tenant's delay in making payments to Landlord for costs of the
Initial Improvements and/or Change Orders in excess of the Landlord's
Contribution; or

          (g) Any other act or omission by Tenant, its agents, contractors or
persons employed by any of such persons.

If the Commencement Date is delayed for any reason, then Landlord shall cause
Landlord's Architect to certify the date on which the Initial Improvements would
have been completed but for such Tenant Delay, or were in fact completed without
any Tenant Delay.

     5.   ACCESS BY TENANT PRIOR TO COMMENCEMENT OF TERM.  Landlord shall permit
Tenant and its agents to enter the Premises not less than fifteen (15) days
prior to the 

                                      C-2
<PAGE>
 
Commencement Date to prepare the Premises for Tenant's use and occupancy. Such
permission shall constitute a license only, conditioned upon Tenant's:

          (a) working in harmony with Landlord and Landlord's agents,
contractors, workmen, mechanics and suppliers and with other tenants and
occupants of the Building;

          (b) obtaining in advance Landlord's approval of the contractors
proposed to be used by Tenant and depositing with Landlord in advance of any
work the contractor's affidavit for the proposed work and the waivers of lien
from the contractor and all subcontractors and suppliers of material; and

          (c) furnishing Landlord with such insurance as Landlord may require
against liabilities which may arise out of such entry.

     Landlord shall not be liable in any way for any injury, loss or damage
which may occur to any of Tenant's property or installations in the Premises
prior to the Commencement Date. Tenant shall protect, defend, indemnify and save
harmless Landlord from all liabilities, costs, damages, fees and expenses
arising out of the activities of Tenant or its agents, contractors, suppliers or
workmen in the Premises or the Building.  Any entry and occupation permitted
under this Section shall be governed by Section 5 and all other terms of the
Lease.

     6.   LATE COMPLETION DATE.  In the event the Completion Date has not
occurred by August 21, 1998 (subject to any Tenant Delays), Landlord shall
relocate Tenant to temporary space ("Temporary Space") elsewhere.  Landlord
shall deliver the Temporary Space to Tenant on or before August 21, 1998.  The
Temporary Space shall be located in no more than three (3) buildings within the
Austin, Texas metropolitan area, and shall contain no less than 45,000 rentable
square feet in the aggregate in occupiable condition, but otherwise "as is."
Tenant's gross rent for the Temporary Space shall be $14.50 per rentable square
foot per year from August 21, 1998 through and including November 30, 1998, and
$0.00 per rentable square foot thereafter, continuing until Landlord delivers
the substantially completed Premises to Tenant. Landlord shall reimburse Tenant
for Tenant's reasonable cost associated with such move (including, but not
limited to, the cost of installing equipment and telecommunications lines) from
Tenant's current office space location to the Temporary Space upon Tenant's
delivery to Landlord of paid invoices evidencing such costs.

     7.   MISCELLANEOUS.  Terms used in this Appendix C shall have the meanings
assigned to them in the Lease.  The terms of this Appendix C are subject to the
terms of the Lease.  Notwithstanding anything to the contrary in this Appendix
C, the total amount payable by Tenant shall not exceed $1,422,263, less the
Landlord's Contribution, but increased by the cost of any changes to the Initial
Improvements from:  (i) the "Schematic Test Fit" and/or the "Architectural
Pricing Criteria for the NetSolve Lease in the Riata Office Park Austin, Texas"
each of which as prepared by RTG/Partners, Inc. and dated August 4, 1997; and/or
(ii) the "Mechanical/Electrical Pricing Criteria for the NetSolve Lease in the
Riata Office Park, Austin, Texas" prepared by MEJ & Associates, Inc. on August

                              SPECIAL PROVISIONS


     1.   EXTENSION OPTION.  Subject to Subsections B and C below, Tenant may at
its option extend the Term of this Lease for the entire Premises for one period
of five (5) years (the "Renewal Term") upon the same terms contained in this
Lease, excluding the provisions of Appendix C of the Lease and except for the
amount of Base Rent payable during the Renewal Term.  Tenant shall have no
additional extension option.

     A.   The Base Rent during the Renewal Term shall be the greater of (i) the
Base Rent applicable to the last day of the final Lease Year prior to the
applicable Renewal Term, or (ii) the then prevailing market rate for a
comparable term commencing on the first day of the Renewal Term for tenants of
comparable size and creditworthiness for comparable space (including the extent
of tenant improvements) in the Project and other first class office buildings in
the vicinity of the Project as reasonably determined by Landlord.

     B.   To exercise its option, Tenant must deliver an initial non-binding
notice to Landlord not more than twelve (12) months, nor less than nine (9)
months, prior to the proposed commencement of the Renewal Term.  Within ninety
(90) days of Landlord's receipt of Tenant's initial non-binding notice, Landlord
shall calculate and inform Tenant of the Base Rent for the Premises during the
Renewal Term.  Such calculation shall be final and shall not be recalculated at
the actual commencement of the Renewal Term if any.  Tenant shall give Landlord
final binding notice of intent to exercise its option to extend within fifteen
(15) days after receiving Landlord's calculation of Base Rent.  If Tenant fails
to give either its initial nonbinding notice or its final binding notice timely,
Tenant will be deemed to have waived its option to extend.

     C.   Tenant's option to extend this Lease is subject to the conditions
that:  (i) that on the date that Tenant delivers its final binding notice
exercising its option to extend, Tenant is not in default under this Lease after
the expiration of any applicable notice and cure periods, and (ii) Tenant shall
not have assigned this Lease, or sublet any portion of the Premises under a
sublease which is in effect at any time during the final 12 months of the Term.

     D.   Tenant agrees to accept the Premises at the commencement of the
Renewal Term in its then-present condition, "AS IS" and "WITH ALL FAULTS."

     2.   RIGHT OF FIRST REFUSAL.  Subject to Subsection B below, Landlord
hereby grants to Tenant for the term of the Lease a right of first refusal for
the balance of the first (1st) floor of the Building, comprising approximately
21,455 Rental Square Feet (subject to adjustment pursuant to Section 1C of the
Lease) (the "Expansion Space"), to be exercised in accordance with Subsection A
below.

     A.   In the event Landlord receives a bona fide offer from a third party to
lease all or a portion of the Expansion Space, or Landlord makes such an offer
to a third party with respect 

                                      F-1
<PAGE>
 
to all or a portion of the Expansion Space, Landlord shall so notify Tenant
("Landlord's RFR Notice"), identifying the available Expansion Space (the "RFR
Space"). Landlord's RFR Notice shall contain the terms upon which Landlord is
willing to lease the RFR Space, including base rent at the then prevailing
market rate for a comparable term for tenants of comparable size and
creditworthiness for comparable space in the Project and other first class
office buildings in the vicinity of the Project as reasonably determined by
Landlord. Tenant shall notify Landlord within ten (10) business days of receipt
of Landlord's RFR Notice whether it desires to lease the RFR Space on the terms
set forth in Landlord's RFR Notice. If Tenant does not notify Landlord within
said 10-business day period that it will lease the RFR Space, Tenant shall be
deemed to have refused the RFR Space. After any refusal, Tenant shall have no
further right of first refusal for such RFR Space and Landlord shall be free to
lease such space to any party for any term. If Tenant exercises its right of
first refusal with respect to the RFR Space, such space shall be added to the
Premises for all purposes of this lease for the remaining Term of the Lease on
(a) the terms specified in Landlord's RFR Notice, and (b) the terms of this
Lease to the extent that they do not conflict with the terms specified in
Landlord's RFR Notice, except that the terms of Landlord's RFR Notice shall not
apply during any Renewal Term, and instead, the terms of the Lease applying to
the remainder of the Premises during the Renewal Term shall also apply to the
RFR Space.

     B.   Tenant's right of first refusal is subject to the conditions that:
(i) on the date that Tenant delivers its notice exercising its right of first
refusal, Tenant is not in default under this Lease after the expiration of any
applicable notice and cure periods, (ii) Tenant shall not have assigned the
Lease, or sublet any portion of the Premises under a sublease which is in effect
at any time during the period commencing with Tenant's delivery of its notice
and ending on the date the RFR Space is added to the Premises, and (iii) Tenant
failed to exercise its option under Paragraph 2 of this Appendix F to lease the
Expansion Space.

     C.   Promptly after Tenant's exercise of its right of first refusal under
this Paragraph 3, Landlord shall execute and deliver to Tenant an amendment to
the Lease to reflect changes in the Premises, Base Rent, Tenant's Proportionate
Share and any other appropriate terms changed by the addition of the RFR Space.
Within fifteen (15) days after Tenant's receipt of an accurate amendment from
Landlord, Tenant shall execute and return the amendment.

     This Lease establishes the general terms and conditions by which Lessor may
lease to Lessee the Equipment (the "Equipment") listed on each Equipment
Schedule executed periodically pursuant to this Lease.  Each such Equipment
Schedule shall incorporate by reference the terms of this Lease, and shall be a
separate lease agreement as to the Equipment listed thereon for all purposes,

provisions of this Lease, the provisions of such Equipment Schedule shall
prevail.

2.   DEFINITIONS:

     (a) The "Installation Date" means the date determined in accordance with
the applicable Equipment Schedule.

     (b) The "Commencement Date" means, as to  any item of the Equipment

     (c) The "Daily Rental" means 1/30th of the amount set forth as the monthly

3.   TERM OF LEASE:

     The term of this Lease, as to all Equipment designated on any Equipment

the applicable Equipment Schedule from the Commencement Date for the last item
of Equipment to be installed (the "Initial Term").  The term of this Lease for
all such Equipment shall be automatically extended for successive monthly
periods until terminated in accordance with this Lease.  Any termination shall
be effective only on the last day of the Initial Term or the last day of any
such successive period.

4.   RENTAL:

     The monthly rental payable hereunder is as set forth in the Equipment

                                       1
<PAGE>
 
on the first day of a month, the rental for that period of time from the
Installation Date until the Commencement Date shall be an amount equal to the
Daily Rental multiplied by the number of days from (and including) the
Installation Date to (but not including) the Commencement Date and shall be due
and payable on the Installation Date. In addition to the monthly rental set
forth in the Equipment Schedule(s), Lessee shall pay to Lessor an amount equal
to all taxes paid, payable or required to be collected by Lessor, however
designated, which are levied or based on the rental, on the Lease or on the
Equipment or on its purchase for lease hereunder, or on its use, lease,
operation, control or value (including, without limitation, state and local
privilege or excise taxes based on gross revenue), any penalties or interest in
connection therewith which are attributable to Lessee's negligence or taxes or
amounts in lieu thereof paid or payable by Lessor in respect of the foregoing,
but excluding taxes based on Lessor's net income. Personal property taxes
assessed on the Equipment during the term hereof shall be paid by Lessee. Lessee
agrees to file, on behalf of Lessor, all required property tax returns and
reports concerning the Equipment with all appropriate governmental agencies,
and, within not more than thirty (30) days after the due date of such filing to
send Lessor confirmation of such filing.
 
     Interest on any past due payments, including but not limited to
administrative charges and any other charges or fees arising out of or related
to this Lease, shall accrue at the rate of 1 1/2% per month, or if such rate
shall exceed the maximum rate allowed by law, then at such maximum rate, and
shall be payable on demand.  Charges for taxes, penalties and interest shall be
promptly paid by Lessee when invoiced by Lessor.

     As security for the full performance of all of the Lessee's obligations
under each Equipment Schedule, Lessee shall, simultaneously with the execution
and delivery of each Equipment Schedule, deposit with Lessor the amount set
forth on such Equipment Schedule.  The security deposit shall be promptly
returned to the Lessee by the Lessor upon the expiration of such Equipment
Schedule and return of all Equipment, provided that all Lessee obligations under

will at all times keep the Equipment in its sole possession and control.  The

     (e) After prior notice to Lessor, Lessee may, at its own expense, make
alterations in or add attachments to the Equipment, provided such alterations or
attachments do not interfere with the normal and satisfactory operation or
maintenance of the Equipment or with Lessee's ability to obtain and maintain the
maintenance contract required by Section 5(h) hereof.  The manufacturer or other
organization selected by Lessee and approved in writing by Lessor to maintain
the Equipment ("Maintenance Organization") may incorporate engineering changes
or make temporary alterations to the Equipment upon request of Lessee.  All such
alterations and attachments shall be and become the property of Lessor or, at
the option of Lessee, shall be removed by Lessee and the Equipment restored, at
Lessee's expense, to its original condition as of the Installation Date thereof,
reasonable wear and tear only excepted, and upon the removal and restoration,
the alteration and/or attachment which was made by Lessee shall become the
property of Lessee.

     (f) So long as Lessee is not in default hereunder, neither Lessor nor any
party claiming through or under Lessor shall interfere with Lessee's use or
possession of any Equipment during the term of this Lease.

     (g) Lessee shall, during the term of this Lease, at its expense, keep the
Equipment in good working order and condition and make all necessary
adjustments, repairs and replacements and shall not use or permit the Equipment
to be used in any manner or for any purpose for which, in the opinion of the
manufacturer, the Equipment is not designed or reasonably suitable.

     (h) Unless otherwise set forth in the applicable Equipment Schedule, Lessee
shall, during the term of this Lease, at its own expense, enter into and
maintain in force a contract with the manufacturer or the Maintenance
Organization covering at least prime shift maintenance of each item of
Equipment.  Such contract shall commence upon expiration of the manufacturer's
warranty period, if any, relating to such item.  Lessee shall furnish Lessor
with a copy of such contract(s).

     (i) At the termination of the applicable Equipment Schedule, Lessee shall,
at its expense, return not less than all the Equipment subject thereto to Lessor
(at the location designated by Lessor within the Continental United States) in
the same operating order, repair, condition and appearance as on the
Installation Date, reasonable wear and tear only excepted, with all engineering
and safety changes prescribed by the manufacturer or Maintenance Organization
incorporated therein.  Lessee shall, prior to such termination, arrange and pay
for any repairs, changes and manufacturer's certifications as are necessary for
the manufacturer or Maintenance Organization to accept the Equipment under
contract maintenance at its then standard rates.  Lessee shall return all
accessories supplied with the Equipment, including but not limited to all
manuals, cables and software diskettes. Lessee shall promptly pay, after receipt
of an invoice therefore, all costs and expenses pertaining to the replacement of
any missing items and for the repair of any Equipment, together with any audit,
inspection or certification charges reasonably incurred by Lessor.

6.   LEASEHOLD RIGHTS AND INSPECTION:

     (a) Lessee shall have no interest in the Equipment other than the rights
acquired as a lessee hereunder and the Equipment shall remain personalty
regardless of the manner in which it may be installed or attached.  Lessee
shall, at Lessor's request, affix to the Equipment, tags, decals or plates

                                       3
<PAGE>
 
furnished by Lessor, indicating Lessor's ownership and Lessee shall not permit
their removal or concealment.  Lessee shall replace any such tag, decal or plate
which may be removed or destroyed or become illegible.  Lessee shall keep all
Equipment free from any marking or labeling which might be interpreted as a
claim of ownership thereof by Lessee or any party other than Lessor or anyone
claiming through Lessor.

     (b) Lessee shall keep the Equipment free and clear of all liens and
encumbrances except liens or encumbrances arising through the actions or
omissions of Lessor.  Lessee shall not assign or otherwise encumber this Lease
or any of its rights hereunder or sublease the equipment without the prior
written consent of Lessor except that Lessee may assign this Lease or sublease
the Equipment to its parent or any subsidiary corporation, or to a corporation
which shall have acquired all or substantially all of the property of Lessee by
merger, consolidation or purchase.  No permitted assignment or sublease shall
relieve Lessee of any of its obligations hereunder.

     (c) Lessor or its agents shall have free access to the Equipment at all
reasonable times for the purpose of inspection and for any other purpose
contemplated by this Lease.

     (d) Lessee shall immediately notify Lessor of all details concerning any
damage to, or loss of, the Equipment arising out of any event or occurrence
whatsoever, including but not limited to, the alleged or apparent improper
manufacture, functioning or operation of the Equipment.

7.   NO WARRANTIES BY LESSOR:

     Lessee represents that, at the Installation Date thereof, it shall have (a)
thoroughly inspected the Equipment; (b) determined for itself that all items of
Equipment are of a size, design, capacity and manufacture selected by it; and
(c) satisfied itself that the Equipment is suitable for Lessee's purposes.
LESSOR SUPPLIES THE EQUIPMENT AS IS AND NOT BEING THE MANUFACTURER OF THE
EQUIPMENT, THE MANUFACTURER'S AGENT OR THE SELLER'S AGENT, MAKES NO WARRANTY OR
REPRESENTATION, EITHER EXPRESS OR IMPLIED AS TO THE EQUIPMENT'S MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, DESIGN, CONDITION, QUALITY, CAPACITY, MATERIAL
OR WORKMANSHIP OR AS TO PATENT INFRINGEMENT OR THE LIKE, it being agreed that
all such risks, as between Lessor and Lessee, are to be borne by Lessee.  Lessee
agrees to look solely to the manufacturer or to suppliers of the Equipment for
any and all warranty claims and any and all warranties made by the manufacturer
or the supplier of Lessor are, to the extent to which the same may be
assignable, hereby assigned to Lessee for the term of the applicable Equipment
Schedule. Lessee agrees that Lessor shall not be responsible for the delivery,
installation, maintenance, operation or service of the Equipment or for delay or
inadequacy of any or all of the foregoing. Lessor shall not be responsible for
any direct or consequential loss or damage resulting from the installation,
operation or use of the Equipment or otherwise.  Lessee will defend, indemnify
and hold Lessor harmless against any and all claims, demands and liabilities
arising out of or in connection with the design, manufacture, possession or
operation of the Equipment.

                                       4

8.   RISK OF LOSS ON LESSEE:

     (a) Beginning on the Installation Date thereof and continuing until the
Equipment is returned to Lessor as provided in this Lease, Lessee relieves
Lessor of responsibility for all risks of physical damage to or loss or
destruction of the Equipment, howsoever caused.  During the term of this Lease
as to any Equipment Schedule, Lessee shall, at its own expense, keep in effect
"all risk" property insurance and public liability insurance policies covering
the Equipment designated in each Equipment Schedule.  The public liability
insurance policy shall be in such amount as is reasonably acceptable to Lessor.
The "all risk" property insurance policy shall be for an amount not less than
the replacement cost of the Equipment.  Lessor, its successors and assigns
and/or such other party (to the extent such party has an insurable interest in
the Equipment) as may be designated by any thereof to Lessee, in writing, shall
be named as additional insureds and loss payees on such policies, which shall be
written by an insurance company of recognized responsibility which is reasonably
acceptable to Lessor.  Evidence of such insurance coverage shall be furnished to
Lessor no later than the Installation Date set forth in the Equipment
Schedule(s) and, from time to time, thereafter as Lessor may request.  Such
policies shall provide that no less than ten days written notice shall be given
Lessor and any other party named as loss payee prior to cancellation of such
policies for any reason.  To the extent of Lessor's interest therein, Lessee
hereby irrevocably appoints Lessor or any other party named as loss payee as
Lessee's attorney-in-fact coupled with an interest to make claim for, receive
payment of, and execute any and all documents that may be required to be
provided to the insurance carrier in substantiation of any such claim for loss
or damage under said insurance policies, and to endorse Lessee's name to any and
all drafts or checks in payment of the loss proceeds, provided however, that
Lessor shall not execute documents on behalf of Lessee unless Lessee, after
three days prior notice from Lessor, has failed to execute such documents.

     (b) If any item of Equipment is rendered unusable as a result of any
physical damage to, or destruction of, the Equipment, Lessee shall give to
Lessor immediate notice thereof and this Lease shall continue in full force and
effect without any abatement of rental.  Lessee shall determine, within fifteen
(15) days after the date of occurrence of such damage or destruction, whether
such item of Equipment can be repaired.  In the event Lessee determines that the
item of Equipment cannot be repaired, Lessee shall either, at its expense,
promptly replace such item of Equipment and convey title to such replacement to
Lessor free and clear of all liens and encumbrances, and this Lease shall
continue in full force and effect as though such damage or destruction had not
occurred, or pay Lessor therefor in cash the Stipulated Loss Value (defined
below) within thirty (30) days of such loss or damage.  "Stipulated Loss Value,"
as used herein, shall be an amount as shown on Exhibit A to the applicable
Equipment Schedule.  In the event Lessee determines that such item of Equipment
can be repaired, Lessee shall cause such item of Equipment to be promptly
repaired.  All proceeds of insurance received by Lessor, the designated loss
payee, or Lessee under the policy referred to in the preceding paragraph of this
Section shall be applied toward the cost of any such repair or replacement so
long as Lessee shall not be in default of its obligations hereunder.

                                       5

9.   EVENTS OF DEFAULT AND REMEDIES:

     The occurrence of any one of the following shall constitute an Event of
Default hereunder:

     (a) Lessee fails to pay an installment of rent on or before the date when
the same becomes due and payable and such failure continues for a period of five
days;

     (b) Lessee attempts to remove, sell, transfer, encumber, sublet or part
with possession of the Equipment or any items thereof, except as expressly
permitted herein.

     (c) Lessee shall fail to observe or perform any of the other obligations
required to be observed or performed by Lessee hereunder and such failure shall
continue uncured for ten (10) days after written notice thereof to Lessee by
Lessor or the then assignee hereof.

     (d) Lessee ceases doing business as a going concern, makes an assignment
for the benefit of creditors, admits in writing its inability to pay its debts
as they become due, files a voluntary petition of bankruptcy, is adjudicated a
bankrupt or an insolvent, files a petition seeking for itself any
reorganization, arrangement, composition, readjustment, liquidation, dissolution
or similar arrangement under any present or future statute, law or regulation or
files an answer admitting the material allegations of the petition filed against
it in any such proceeding, consents to or acquiesces in the appointment of a
trustee, receiver, or liquidator of it or of all or any substantial part of its
assets or properties, or if it or its shareholders shall take any action looking
to its dissolution or liquidation.

     (e) Within forty-five (45) days after the commencement of any proceedings
against Lessee seeking reorganization, arrangement, readjustment, liquidation,
dissolution or similar relief under any present or future statute, law or
regulation, such proceedings shall not have been dismissed, or if within forty-
five (45) days after the appointment without Lessee's consent or acquiescence of
any trustee, receiver or liquidator of it or of all or any substantial part of
its assets and properties, such appointment shall not be vacated.

     (f) Lessee defaults in the performance or observation of any term,
condition or covenant of any loan agreement, indenture, trust agreement, lease
or similar agreement to which Lessee is a party or by which Lessee is bound and
such default continues beyond any applicable cure period;

     (g)  Lessee enters into any transaction which adversely affects a
significant portion of the business value of Lessee and which affects the
ability of the Lessee to repay the Lessee's obligations under the Lease.


     Upon the occurrence of an Event of Default, Lessor may at its option do any
one or more of the following:  (i) by notice to Lessee terminate this Lease as
to any or all Equipment Schedules; (ii) whether or not this Lease is terminated
as to any or all Equipment Schedules, take possession on not less than three (3)
days' notice of any or all of the Equipment listed on any or all Equipment
Schedules, wherever situated, and for such purpose, enter upon any premises
without liability for 

                                       6
<PAGE>
 
so doing or Lessor may cause Lessee and Lessee hereby agrees, to return said
Equipment to Lessor as provided in this Lease; (iii) recover from Lessee, as
liquidated damages for loss of a bargain and not as a penalty, all past due
amounts as well as an amount equal to the present value of all monies to be paid
by Lessee during the remaining Initial Term or any successive period then in
effect, calculated by discounting at the rate of six percent (6%) per annum
compounded monthly, which payment shall become immediately due and payable; and
(iv) sell, dispose of, hold, use or lease any Equipment as Lessor in its sole
discretion may determine (and Lessor shall not be obligated to give preference
to the sale, lease or other disposition of the Equipment over the sale, lease or
other disposition of similar equipment owned or leased by Lessor).

     In the event that Lessee shall have first paid to Lessor or its assigns the
liquidated damages referred to in (iii) above, Lessee shall thereafter be
entitled to receive all rentals or proceeds received from any reletting of the
Equipment during the balance of the Initial Term (after deduction of Lessor's
expected residual value of the Equipment at the expiration of the Initial Term
or any extension thereof and of all expenses incurred in connection therewith)
said amount never to exceed the amount of the liquidated damages paid by Lessee.
Lessee agrees that Lessor shall have no obligation to sell the Equipment.
Lessee shall in any event remain fully liable for reasonable damages as provided
by law and for all costs and expenses incurred by Lessor or its assigns on
account of such default including but not limited to all court costs and
reasonable attorney's fees. Lessee hereby agrees that, in any event, it will be
liable for any deficiency after any lease or other disposition of the Equipment.
The rights afforded Lessor hereunder shall not be deemed to be exclusive, but
shall be in addition to any rights or remedies provided by law.

10.  NET LEASE:

     Except as otherwise specifically provided in this Lease, it is understood
and agreed  that this is a net lease, and that, as between Lessor and Lessee,
Lessee shall be responsible for all costs and expenses of every nature
whatsoever arising out of or in connection with or related to this Lease or the
Equipment (including, but not limited to, transportation in and out, rigging,
manufacturer's approved packing, installation, certification costs and
disconnect charges).  Lessee hereby agrees that in the event that Lessee fails
to pay or perform any obligation under this Lease, Lessor may, at its option,
pay or perform said obligation and any payment made or expense incurred by
Lessor in connection therewith shall become additional rent which shall be due
and payable by Lessee upon demand.  Lessee acknowledges that Lessor may, from
time to time, and at Lessee's request, execute and deliver purchase orders
pertaining to the purchase of equipment to be leased pursuant to this Lease.
Lessee agrees that it will indemnify and hold Lessor harmless from and against
any and all loss, cost, liability and expense that Lessor may incur as a result
of the execution and delivery of such purchase orders.

 11. ASSIGNMENT:

     Lessee agrees that Lessor may transfer or assign all or any part of
Lessor's right, title, and interest in, under or to the Equipment and this Lease
and any or all sums due or to become due pursuant to any of the above, to any
third party (the "Assignee") for any reason and that the Assignee may so re-
assign and transfer; provided that no such assignment or transfer shall relieve
Lessor of 

                                       7
<PAGE>
 
any obligations hereunder. Lessee agrees that upon receipt of written notice
from Lessor or Assignee of such assignment, Lessee shall perform all of its
obligations hereunder for the benefit of Assignee and any successor assignee
and, if so directed, shall pay all sums due or to become due thereunder directly
to the Assignee or to any other party designated by the Assignee. Lessee hereby
covenants, represents and warrants as follows and agrees that the Assignee and
any successor assignee shall be entitled to rely on and shall be considered a
third party beneficiary of the following covenants, representations and
warranties: (i) Lessee's obligations hereunder are absolute and unconditional
and are not subject to any abatement, reduction, recoupment, defense, offset or
counterclaim available to Lessee for any reason whatsoever including operation
of law, defect in the Equipment, failure of Lessor or Assignee to perform any of
its obligations hereunder or for any other cause or reason whatsoever, whether
similar or dissimilar to the foregoing; (ii) Lessee shall not look to Assignee
or any successor assignee to perform any of Lessor's obligations hereunder;
(iii) Lessee will not amend or modify this Agreement without the prior written
consent of the Assignee and any successor assignee; and (iv) Lessee will send a
copy to Assignee and any successor assignee of each notice which Lessee sends to
Lessor.

12.  REPRESENTATIONS AND WARRANTIES OF LESSEE:

     Lessee represents and warrants to Lessor and its assigns, as follows:

     1.  The execution, delivery and performance of this Lease has been duly
authorized and, upon execution by Lessor and Lessee, will constitute a valid
obligation binding upon and enforceable against Lessee in accordance with its
terms, subject to laws governing creditors' rights;

     2.  The performance by Lessee will not result in any breach, default or
violation of, Lessee's certificate of incorporation or by-laws or any agreement
to which Lessee is a party;

     3.  Lessee is in good standing in its jurisdiction of incorporation and in
any jurisdiction in which any of the Equipment is to be located; and

     4.  Any and all financial statements or other information with respect to
Lessee heretofore furnished by Lessee to Lessor was, when furnished, and remains
at the time of execution of this Lease, true and complete.

     Lessor represents and warrants to Lessee as follows:

     1.  The execution, delivery and performance of this Lease has been duly
authorized and, upon execution by Lessor and Lessee, will constitute a valid
obligation binding upon and enforceable against Lessor in accordance with its
terms, subject to laws governing creditors' rights; and

     2.  The performance by Lessor will not result in any breach, default or
violation of, Lessor's certificate of incorporation or by-laws or any agreement
to which Lessor is a party;

                                       8
<PAGE>
 
     The foregoing representations and warranties shall survive the expiration
or termination of this Lease.

13.  END OF LEASE:

     Provided (i) no Event of Default has occurred and is continuing and (ii)
Lessee has made all payments in accordance with the Lease, upon written notice
furnished by Lessee no later than four (4) months prior to the expiration of the
Initial Term, Lessee may, with respect to each Equipment Schedule (if set forth
in such Equipment Schedule) either:

     (a) Extend the Initial Term for not less than all the Equipment (i) for the
additional period set forth on the applicable Equipment Schedule, and (ii) at
the Monthly Rental set forth on the Equipment Schedule.  Provided all payments
have been made in accordance with the Lease and there shall be no default under
the Lease by Lessee, title to the Equipment shall pass to Lessee at the
expiration of the 12 month extension and upon payment of $1.00.;

     (b) Extend the Initial Term for not less than all the Equipment for an
additional 12 months at Fair Market Value rental;

     (c) Purchase not less than all the Equipment at Fair Market Value for a
purchase price equal to the Fair Market Value thereof as of the end of the
Initial Term, plus any taxes applicable at the time of purchase.  The purchase
price shall be paid by Lessee to Lessor at least thirty (30) days before the
expiration of the Initial Term;

     (d) Terminate the applicable Equipment Schedule and return not less than
all the Equipment, subject to a remarketing charge equal to the percentage set
forth in the applicable Equipment Schedule of Lessor's original Purchase Price
for the Equipment; or

     (e) Such other alternatives as may be set forth on the Equipment Schedule.

If, on or before a date which is sixty (60) days prior to the expiration of the
Initial Term, Lessor and Lessee are unable to agree upon a determination of the
Fair Market Value of the Equipment, the Fair Market Value (to be determined in
accordance with the definition set forth in this Section) shall be conclusively
established not less than thirty (30) days prior to the expiration of the
Initial Term by an independent appraiser selected by Lessor.  Lessor shall
notify Lessee of the name and address of said appraiser.  The costs of such
appraiser shall be paid by Lessee within ten (10) days after receipt of an
invoice therefor.

For purposes hereof, Fair Market Value shall mean the amount that would obtain
in a retail arm's length transaction between an informed and willing lessee-
buyer in possession and an informed and willing lessor-seller.  Rental charges
previously paid pursuant to the applicable Equipment Schedule shall have no
effect on the determination of Fair Market Value.  Unless otherwise stated in
the Equipment Schedule: the Fair Market Value for items set forth on the
Equipment Schedule which do not have a readily ascertainable market value,
(including but not limited to software, cabling and certain equipment) shall be
determined by multiplying the Lessor's acquisition cost of such items 

                                       9
<PAGE>
 
by a fraction, the numerator of which shall be the Fair Market Value of the
other items and the denominator of which shall be the Lessor's acquisition cost
of such other items; and the determination of Fair Market Value shall be based
upon the assumption that all items set forth on the Equipment Schedule or
included with the Equipment may be transferred to, and used by, a third party
user. In such determination, all alternative uses in the hands of each buyer or
lessee, including, without limitation, the further leasing of the Equipment
shall be taken into account in making such determination.

If, for any reason, the parties are unable to agree on the Fair Market Value
with respect to said purchase or rental, then the Lease with respect to the
Equipment shall remain in full force and effect.

14.  MISCELLANEOUS:

     (a)  During the term of this Lease, Lessee hereby agrees to deliver to
Lessor or Assignee and any successor assignee a copy of Lessee's monthly
unaudited financial statements, and the annual financial budget for the upcoming
year as soon as available and as it may be adjusted during the year.  Lessee
shall also furnish, as soon as available and in any event within ninety (90)
days after the last day of Lessee's fiscal year, a copy of Lessee's annual
audited statements and consolidating and consolidated balance sheet, if any, as
of the end of such fiscal year, accompanied by the opinion of an independent
certified public accounting firm of recognized standing.  The Lessee shall
furnish such other financial information as may be reasonably requested by
Lessor, including but not limited to any material changes in budgets or
financial reports furnished to the Lessee's Board of Directors or Shareholders.

     (b) This Lease constitutes the entire agreement between Lessee and Lessor
with respect to the Equipment, and except as agreed upon in writing no covenant,
condition or other term or provision hereof may be waived or modified orally.

     (c) All notices hereunder shall be in writing and shall be delivered in
person or sent by registered or certified mail, postage prepaid, or by facsimile
transmission (confirmed by registered mail as set forth in this section) to the
address of the other party as set forth herein or to such other address as such
party shall have designated by proper notice.

     (d) This Lease shall be binding upon and inure to the benefit of Lessor and
Lessee and their respective successors and assigns (including any subsequent
assignee of Assignee).

     (e) If any term or provision of this Lease or the application thereof to
any person is, to any extent, invalid or unenforceable, the remainder of this
Lease, or the application of such provision to the person other than those to
which it is invalid or unenforceable, shall not be affected thereby, and each
provision of this Lease shall be valid and be enforced to the fullest extent
permitted by law.

     (f) No waiver of any of the terms and conditions hereof shall be effective
unless in writing and signed by the party against whom such waiver is sought to
be enforced. Any waiver of the terms hereof shall be effective only in the
specific instance and for the specific purpose given.  The subsequent acceptance
of rental payments hereunder by Lessor shall not be deemed a waiver of any 

                                       10
<PAGE>
 
prior existing breach by Lessee regardless of Lessor's knowledge of such prior
existing breach at the time of acceptance of such rental payments. Where
permitted by law, Lessee authorizes any attorney of record, Clerk of Court or
Prothonotary of any state to appear for and confess judgment (a) against Lessee
for all amounts as to which Lessee is in default under this Agreement and (b)
against Lessee in any action for writ of replevin or possession of the Equipment
but only after providing Lessee three (3) days notice to contest Lessor's claim.
No bond shall be required.

     (g) Lessor is hereby authorized by Lessee to cause this Lease or other
instruments, including Uniform Commercial Code Financing Statements to be filed
or recorded for the purpose of showing Lessor's interest in the Equipment and
Lessee agrees that Lessor may execute such instruments for and on behalf of
Lessee.  In the event Lessor files a Uniform Commercial Code Financing Statement
without the signature of Lessee, Lessor shall promptly furnish a copy of such
Uniform Commercial Code Financing Statement to Lessee.  All filing fees
reasonably incurred by Lessor in connection therewith and filing fees incurred
by Lessor's  assignees in perfecting security interests shall be paid by Lessee
or reimbursed to Lessor by Lessee.

     (h) In the event of any conflict between the terms and conditions of this
Lease and the terms and conditions of any Equipment Schedule(s) or Rider(s)
thereto, the terms and conditions of such Equipment Schedule(s) or Rider(s)
shall prevail.

     (i) No consent or approval provided for herein shall be binding upon Lessor
unless signed on its behalf by an officer of Lessor.  THIS LEASE SHALL BE DEEMED
TO HAVE BEEN MADE IN THE STATE OF CONNECTICUT AND SHALL BE GOVERNED IN ALL
RESPECTS BY THE LAWS OF SUCH STATE.  The Lessee accepts for itself the non-
exclusive jurisdiction of any Federal or State court of competent jurisdiction
in the State of Connecticut in any action, suit or proceeding of any kind
against it which arises out of or by reason of this Lease or any Equipment
Schedule.

     (j) Lessee acknowledges that the late payment by Lessee to Lessor of
monthly rental and other sums due hereunder will cause Lessor harm and to incur
costs not contemplated by this Lease, the precise amount and severity of which
will be difficult to ascertain.  Such costs include, but are not limited to,
administrative, accounting and legal charges which Lessor may incur due to such
late payment.  Accordingly, if any monthly rent or any other sum due from Lessee
shall not be received by Lessor or Lessor's assignee within twenty (20) days
after the same is due, Lessee shall pay to Lessor or Lessor's assignee a late
charge equal to five per cent (5%) of such overdue amount monthly until such
overdue amount is paid.  Lessee acknowledges that such late charge represents a
fair and reasonable estimate of the cost Lessor will incur by reason of a late
payment by Lessee.  Acceptance of such late charge by Lessor shall in no event
constitute a waiver of Lessee's default, if any, with respect to such overdue
amounts, nor prevent Lessor from exercising any of the other rights and remedies
which Lessor may have pursuant to this Lease.

     (k) The obligations which Lessee is required to perform during the term of
this Lease shall survive the expiration or other termination of this Lease.

                                       11
<PAGE>
 
     (l)  Lessee will promptly execute and deliver to Lessor such further
documents and assurances and take such further action as Lessor may reasonably
request in order to effectuate the intent and purpose of this Lease and to
establish and protect the rights, interests and remedies intended to be created
in favor of Lessor hereunder, including without limitation, the execution and
filing of financing statements and continuation statements with respect to this
Lease, the Equipment and any Equipment Schedule.  Lessee authorizes Lessor to
effect any such filing and Lessor's reasonable expenses (together with the
reasonable expenses of Lessor's assignees in this regard) shall be payable by
Lessee on demand.

Master lease dated as of January 30, 1998, by and between TRIMARC FINANCIAL
("Lessor"), with its principal office stated above, and NETSOLVE, INCORPORATED
("Lessee") having its principal office at 9130 JOLLYVILLE ROAD SUITE 200,
AUSTIN, TEXAS 78759-7475.

1.   MASTER LEASE:  This is a Master Lease Agreement (hereafter "Lease").  The
terms of each Lease Schedule(s) (hereafter "Schedule(s)") hereto and/or
hereafter annexed are subject to any and all terms and conditions set forth
herein.  Subject to the following terms and conditions, Lessor hereby leases to
and/or grants to Lessee the right to use certain items of property (regardless
of the nature of which and without distinction, collectively hereafter referred
to as "Equipment", and individually hereafter referred to as an "Item of
Equipment") as described on the attached Schedule(s).  Equipment shall also
include all updates, upgrades, modifications, revisions, new versions,
substitutions, enhancements, maintenance fixes, and any portions or parts
thereof.  Lessee agrees to hire and take and agrees to accept the right to use
that certain Equipment, and such other Equipment described on supplemental
Schedule(s) that the parties from time to time may annex to this Lease.  This
Lease shall give Lessee the right to use the Equipment at the specific location
delineated on the Schedule(s) during the term of this Lease in accordance with
the terms and conditions herein.  Lessee shall not move the Equipment without
Lessor's prior written approval which shall be subject to such terms and
conditions as Lessor may then reasonably require.  Lessor, at its sole option,
may supply Items of Equipment, either new or used, that meet the specifications
of Items of Equipment delineated on the Schedule(s).

2.   QUIET ENJOYMENT:  Provided that no Event of Default has occurred or is
continuing hereunder, Lessor and/or its' Assignees shall not interfere with
Lessee's quiet enjoyment and use of the Equipment.

3.   TERM:  The term of this Lease shall commence upon acceptance of this Lease
by Lessor and shall continue thereafter so long as any Schedule(s) entered into
pursuant to this Lease remains in effect.  As to each Schedule attached to this
Lease, this Lease shall be effective upon acceptance of such Schedule(s) by
Lessor.  The term for any Schedule(s) shall commence on the day that the
Manufacturer/Vendor/Licensor or Lessee certifies that the Equipment has been
delivered to and is usable by Lessee ("Commencement Date").  The Base Term of
the Lease with respect to any Schedule(s) shall be indicated on the respective
Schedule(s) and shall be calculated from the first day of the calendar quarter
following the Commencement Date ("Base Lease Term").  A calendar quarter means a
three-month period commencing on January 1, April 1, July 1 or October 1 of any
calendar year.  The Base Lease Term shall be extended for an additional one-year
period at the final rental 
<PAGE>
 
rate in effect as of the last billing period of the Base Lease Term unless
Lessee provides to Lessor written notice of Lessee's election not to extend the
Base Lease Term at least one hundred eighty (180) days' prior to its expiration.
At the expiration of the Base Lease Term (or, if extended, at the expiration of
the "Extended Base Lease Term"), Lessee shall do one of the following: (A)
purchase all of the Equipment under each Schedule for a mutually agreeable
purchase price; (B) extend the Schedule(s) for a period of one (1) additional
year at the final rental rate in effect as of the last billing period of the
Base Lease Term of the respective Schedule(s); or (C) enter into a new lease
with Lessor to lease property which replaces the Equipment under each Schedule
and which has a cost greater than or equal to the original cost of the
Equipment. With respect to options (A) and (C), Lessor and Lessee shall each
have absolute discretion regarding their agreement or lack of agreement to the
terms of either such arrangement. If the parties have not agreed to either
option (A) or option (C) by the expiration of the Base Lease Term or Extended
Base Lease Term, then option (B) shall prevail. At the end of the extension
period under option (B), this Lease shall continue subject to termination by
either Lessor or Lessee at the end of any calendar month, provided at least one
hundred twenty (120) days' prior written notice of such termination is delivered
to the other.

4.   RENTALS:  The quarterly rent payable for each Schedule shall be the amount
shown on such Schedule.  Lessee shall pay to Lessor the quarterly rent in
advance for each quarter or any part thereof following the Commencement Date.
The first Base Lease Term rental payment shall be made on the first day of the
calendar quarter following the Commencement Date.  A prorata portion of the
quarterly rental charges, based on a daily rental of one-ninetieth (1/90th) of
the quarterly rental calculated from the Commencement Date to the end of the
calendar quarter, shall be due and payable at the Commencement Date.
Installments of rent (or any portion thereof) which are not paid within ten (10)
days after their due date shall be subject to a delinquency payment equal to
five percent (5%) of the late installment.  For delinquent installments of rent
which remain unpaid at the end of each month, Lessee shall also pay to Lessor an
administrative fee equal to two percent (2%) of the aggregate unpaid amount.
All rent shall be paid at the place of business of Lessor shown above or another
place as Lessor may designate by written notice to Lessee.  Except as otherwise
provided in this Lease, Lessee's obligation to pay rent shall be absolute and
unconditional under all circumstances, notwithstanding:  (i) any setoff,
counterclaim, recoupment, defense or other right which Lessee may have against
Lessor for any reason whatsoever; (ii) any defect in the title, right to use,
condition, operation, fitness for use, damage or destruction of or to the
Equipment or any interruptions or cessations in use or possession for any reason
whatsoever; (iii) any insolvency, bankruptcy, reorganization or similar
proceedings instituted by or against Lessee.  Any Deposit shall be returned to
Lessee (without interest) if Lessor does not accept this Lease.  Otherwise, upon
acceptance of this Lease by Lessor, any Deposit shall be applied by Lessor (as
specified on the Schedule) to rental or other payments or costs of Lessor due
and owing under the Lease.  Lessee hereby waives, to the extent permitted by
applicable law, any and all right which it may now or at any time hereafter have
to cancel, terminate, or surrender this Lease except in accordance with the
express terms hereof.

5.   ADDITIONS AND MODIFICATIONS:  Without the prior written consent of Lessor,
and completion of documentation of a form and substance required by Lessor,
Lessee shall make no addition, upgrade, modification, alteration, improvement,
or attachment to any of the Equipment. Lessor, at its sole option, may provide
lease financing for any additions and modifications to 
<PAGE>
 
Equipment required by Lessee during the Lease term, subject to the then
prevailing rates and subject to acceptance by Lessor's Finance Committee.

6.   NO WARRANTIES:  LESSOR NOT BEING THE MANUFACTURER, DEVELOPER, PUBLISHER,
DISTRIBUTOR, OR LICENSOR OF THE EQUIPMENT, MAKES NO WARRANTY OR REPRESENTATION,
EXPRESS OR IMPLIED, AS TO THE FITNESS, QUALITY, DESIGN, CONDITION, CAPACITY,
SUITABILITY, MERCHANTABILITY OR PERFORMANCE OF THE EQUIPMENT OR OF THE MATERIAL
OR WORKMANSHIP THEREOF.  LESSEE AGREES THAT THE EQUIPMENT IS LEASED "AS IS".
LESSEE REPRESENTS THAT ALL OF THE EQUIPMENT IS OF A SIZE, DESIGN AND CAPACITY
SELECTED BY IT, AND THAT IT IS SATISFIED THAT THE SAME IS SUITABLE FOR LESSEE'S
PURPOSES.  NO DEFECT, DAMAGE OR UNFITNESS FOR ANY PURPOSE OF THE EQUIPMENT SHALL
RELIEVE LESSEE OF ANY OBLIGATION UNDER THE LEASE. LESSOR HEREBY ASSIGNS TO
LESSEE ANY AND ALL VENDOR'S WARRANTIES TO THE EXTENT ASSIGNABLE BY LESSOR.
LESSEE AGREES THAT ITS REMEDIES, SHOULD IT FIND FAULT WITH ANY OF THE EQUIPMENT,
SHALL BE AND ARE SOLELY TO THE MANUFACTURER/VENDOR/LICENSOR.  THE FOREGOING
SHALL SURVIVE TERMINATION OF THE RESPECTIVE LEASE TERM AND OF THIS LEASE.

7.   USE, OPERATION AND MAINTENANCE:  Lessee will provide a suitable place for
the installation, operation and maintenance of all Equipment.  Lessee, without
expense to Lessor, shall enter into and keep in force during the entire term of
this Lease the best Manufacturer's/Vendor's/Licensor's Maintenance Agreement and
will ensure that Manufacturer(s)/Vendor(s)/Licensor(s) make all necessary
repairs, adjustments, enhancements, updates, changes and replacements in
accordance with the Maintenance Agreement.  Lessee shall not do anything, or
fail to do anything, to impair the Manufacturer's/Vendor's/Licensor's warranty
with respect to any Equipment.  Lessee shall comply with all laws, rules,
regulations or order of any governmental agency with respect to the Equipment or
to its use, operation, maintenance or storage. Lessor may from time to time
during reasonable business hours enter upon any premises where any of the
Equipment may be located for the purpose of confirming the condition and proper
maintenance of the Equipment.

8.   RISK OF LOSS:  During any period in which the Equipment is in transit to or
from, or in the possession of Lessee, Lessee shall assume all responsibility for
loss, damage, any or all of the Equipment being confiscated, requisitioned,
lost, stolen, destroyed, irreparably damaged from any cause whatsoever, or
relinquished from Lessee's possession for any reason whatsoever, including, but
not limited to, an unauthorized sale or trade-in (collectively, "Event of
Casualty"), and shall indemnify and hold Lessor harmless against the same.
Lessee shall immediately and fully inform Lessor in writing of any Event of
Casualty.  Following an Event of Casualty, Lessee, at its option, provided that
no Event of Default has occurred or is continuing, otherwise at Lessor's option,
shall do one of the following:  1) On the next succeeding rental payment date,
pay to Lessor an amount equal to the Casualty Value as determined by the
Casualty Schedule (for each respective Schedule) as of said rental payment date,
in addition to all past due rentals and other amounts then due and owing, or 2)
Replace the Equipment with identical Equipment of equal or greater value in a
commercially expedient manner, completing documentation required by Lessor to
perfect Lessor's security interest in the replacement Equipment, and provided no
interruption in rental payments.  The 
<PAGE>
 
Casualty Value shall be calculated by multiplying the Equipment's original cost
(entire amount paid by Lessor to Manufacturer/Vendor/Licensor) by the percentage
factor agreed to by Lessee and Lessor as set forth in the Casualty Schedule.
Upon Lessee's payment to Lessor of the Casualty Value, the rental for such
Schedule(s) shall cease to accrue as of the date the payment is tendered by
Lessee to Lessor, and the term of the Lease as to the Schedule(s) shall
terminate. Insurance proceeds received by Lessor as a result of an Event of
Casualty with respect to any Schedule(s) shall be applied to reduce Lessee's
obligation to pay the Casualty Value.

9.   INDEMNITY: Lessee assumes liability for, and hereby agrees, at its own cost
and expense, to indemnify, defend, and hold harmless Lessor, its agents,
employees, officers, directors, successors and assigns, from and against any and
all liabilities, losses, damages, injuries, claims (including, without
limitation, claims based upon strict liability), demands, penalties, actions,
costs and expenses, including legal expenses, of any kind or nature arising out
of the use, condition (including, without limitation, latent and other defects,
whether or not discoverable), operation, ownership, selection, delivery, leasing
or return of any items of Equipment (including, without limitation, any claim
for patent, trademark or copyright infringement), regardless of where, how and
by whom operated, or for any interruptions of service, loss of business or
consequential damages. These provisions shall survive the expiration or
termination of this Lease.

10.  INSURANCE: Lessee, at its expense, shall procure and maintain at all times
that this Lease is in effect comprehensive public liability insurance for bodily
injury and property damage resulting from the maintenance, use or transport of
the Equipment; and property and casualty insurance covering all risks of loss or
damage to the Equipment from every cause whatsoever including, without
limitation, fire and theft. All such insurance shall be in such form and amounts
and with such companies as shall be reasonably satisfactory to Lessor. Lessor,
its successor or assigns, shall be named the loss payee with respect to
insurance for damage to or loss of the Equipment and shall be named as an
additional insured on the public liability insurance. All policies shall provide
that no cancellation or material modification of such insurance shall be
effective without thirty (30) days' prior written notice to Lessor, and shall
not be invalidated as to Lessor by any act, omission or neglect of Lessee.

11.  TAXES: Lessee shall pay directly, all License fees, registration fees,
assessments and taxes (federal, state and local), which may now or hereafter be
imposed upon the ownership, possession or use of the Equipment, excepting only
those based on Lessor's income, and Lessee shall keep the Equipment free and
clear of all levies, liens or encumbrances arising therefrom. ALL REQUIRED
PERSONAL PROPERTY TAX RETURNS RELATING TO THE EQUIPMENT SHALL BE FILED BY
LESSEE. Lessee covenants and agrees that Lessor shall be entitled to receive any
and all federal and state tax credits and benefits, if any, applicable to the
Equipment.

12.  OWNERSHIP: Lessee shall at all times acknowledge, protect and defend, at
its own cost and expense, the title and/or rights of Lessor from and against all
claims, liens and legal processes, and keep all Equipment free and clear from
all such claims, liens, and processes. The Equipment is and shall remain
personal property of Lessor. Upon the expiration or termination of this Lease
with respect to any Schedule(s), Lessee at its expense shall return all
Equipment, free of liens or encumbrances, to Lessor. Title to all Equipment
shall at all times remain in Lessor. In the event that
<PAGE>
 
any of the Equipment is Software, as reflected on any Schedule(s), regardless of
the manner in which Lessee obtained the right to possess and use such Software,
and any underlying agreement(s) between Lessee and Licensor, Lessee and Lessor
hereby agree that, for purposes of this Lease, Lessor shall be deemed the
Licensor, with all Licensor rights, but not any of the obligations, legal and
otherwise. Lessee acknowledges that Lessor has paid Licensor for a perpetual
license on any Software included in this Lease, and that Lessee's use of the
Software during the term of this Lease constitutes full and adequate
consideration from Lessor. Lessee hereby agrees that it will not surrender,
transfer, substitute or modify any license agreement pertaining to any Software
that is the subject of any Schedule(s) without first obtaining the written
consent of Lessor.

13.  EFFECTS OF TERMINATION OR EXPIRATION OF LEASE TERM: Immediately upon
expiration or termination of the last applicable Lease Term ("Lease
Termination") as defined under this Lease, Lessee shall fully discontinue its
use of and return to Lessor all of the Equipment. In addition to Lessee's
completing any documentation requested by Lessor to ensure that Lessee is
returning to Lessor all of the Equipment in a manner consistent with the terms
of this Lease, upon Lessor's written request, an authorized officer of Lessee
shall, within ten (10) days thereafter, provide Lessor with a certified written
statement, that: (i) all such tangible Equipment, and/or Software has been
delivered to Lessor; (ii) all intangible records thereof have been destroyed;
(iii) Lessee has not retained such Equipment and/or Software in any form; (iv)
Lessee will not use any Software after termination; and (v) Lessee has not
received from Licensor(s) anything of value relating to or in exchange for
Lessee's use, lease or possession of the Software (including, without
limitation, a trade-in, substitution or upgrade allowance, the right to use the
Software for additional periods or on additional hardware or at additional
locations) other than Lessee's rights to use the Software during the term(s) of
this Lease. Lessee hereby grants Lessor the right (which shall survive
termination of this Lease) to inspect all of Lessee's locations during
reasonable business hours to insure compliance with the provisions of this
paragraph. If for any reason whatsoever Lessee does not immediately return all
of the Equipment upon any Schedule's effective expiration date, the Lease will
continue in full force and effect as to the Equipment not being returned
(hereafter the "Holdover Equipment"), on a month-to-month rental subject to one
hundred twenty (120) days' prior written notice of termination by either party.
The monthly rental for the Holdover Equipment shall be the original cost of the
Equipment multiplied by a monthly lease rental factor of eight percent (8%). The
resulting monthly rental shall become due from and payable by Lessee to Lessor,
pursuant to all the terms and conditions of the Lease.

14.  PERFORMANCE OF LESSEE'S OBLIGATIONS BY LESSOR: If Lessee fails to perform
any of its obligations under this Lease, Lessor may, at its option, perform the
same for the account of Lessee without thereby waiving Lessee's default, and any
amount paid, expense (including reasonable attorneys' fees), penalty or other
liability incurred by Lessor in such performance shall be payable by Lessee to
Lessor upon demand.

15.  DEFAULT: An Event of Default shall occur if: (a) Lessee fails to pay any
installment of rent, or other payment when due, and such failure is not cured
within ten (10) days after written notice thereof; (b) Lessee fails to perform
or observe any of its covenants or obligations set forth in this Lease, and such
failure is not cured for fifteen (15) days after written notice thereof; (c) Any
representation or warranty made by Lessee in this Lease or in any documents in
connection with this
<PAGE>
 
Lease shall be untrue in any material respect; (d) Lessee ceases doing business
as a going concern, makes an assignment for the benefit of creditors, admits in
writing its insolvency, files a voluntary petition in bankruptcy, is adjudicated
bankrupt or insolvent, files a petition, or takes any action seeking any
reorganization, liquidation, dissolution or similar arrangement, or files an
answer admitting the material allegations of a petition filed against it in any
such proceeding, consents to or acquiesces in the appointment of a trustee,
receiver or liquidator of it or of all or a substantial part of its assets; (e)
within sixty (60) days after the commencement of proceedings against Lessee or
its assets seeking reorganization, liquidation, dissolution, attachment or
execution or similar relief, such proceeding shall not have been dismissed, or
if within sixty (60) days after the appointment, without Lessee's consent, of
any trustee, receiver of liquidator of it or all or any substantial part of its
assets, such appointment shall not be vacated; (f) Lessee attempts to remove,
transfer, sell, sublicense, encumber, part with possession, or sublet the
Equipment without Lessor's prior written consent; (g) Lessee attempts to assign
or transfer this Lease or its interest hereunder without Lessor's prior written
consent, or (h) through sale, assignment, buyout, bankruptcy, merger, or any
change of ownership of any type, form or manner, Lessee's credit worthiness
materially deteriorates as judged solely by Lessor.

16.  REMEDIES: If an Event of Default shall occur, Lessor may exercise at its
sole option, but not specifically limited thereto, any one or more of the
following remedies: (a) terminate this Lease and any and/or all of the Schedules
annexed hereto and Lessee's rights hereunder, (b) by court action or other legal
proceeding, enforce performance by Lessee of the applicable covenants of this
Lease or recover damages for the breach, (c) by notice in writing to Lessee,
recover all amounts due on or before the date Lessor declared this Lease to be
in default, plus, as liquidated damages for loss of a bargain and not as a
penalty, accelerate, and declare to be immediately due and payable the present
value of all rentals and other sums payable hereunder discounted at six percent
(6%) without any presentment, demand, protest or further notice (all of which
hereby are expressly waived by Lessee), whereupon the same shall be immediately
due and payable, and (d) enter upon Lessee's premises where any of the Equipment
is located with or without notice or process of law and free from all claims by
Lessee and take immediate possession of the Equipment. The exercise of any of
the foregoing remedies by Lessor shall not constitute a termination of this
Lease unless Lessor so notifies Lessee in writing. At Lessor's sole option,
Lessor may sell, lease or otherwise dispose of the Equipment in any form or
manner determined by Lessor. In the event that Lessor releases the Equipment,
any rental received therefrom by Lessor for the remaining Lease Term (as defined
in this Lease) shall be applied to the payment of: (i) all costs and expenses
(including reasonable attorneys' fees) incurred by Lessor, and (ii) the rentals
for the remainder of the Lease Term and all other sums then remaining unpaid
under this Lease. All rentals received by Lessor for the period commencing after
the remaining Lease Term shall be retained by Lessor. In the event that Lessor
shall sell the Equipment, the proceeds thereof shall be applied to the sum of:
(i) all costs and expenses (including reasonable attorneys' fees) incurred by
Lessor in repossessing and disposing of such Equipment, (ii) rentals accrued
under this Lease, but unpaid up to the time of such disposition, (iii) any and
all other sums other than rentals then owing to Lessor by Lessee hereunder, and
(iv) the Casualty Value of such Equipment determined as of the date of such
disposition in accordance with Section 8 herein. The remaining balance of such
proceeds, if any, shall be applied first to reimburse Lessee for any sums
previously paid by Lessee as liquidated damages, and any remaining amounts shall
be retained by Lessor. Lessee shall remain liable to Lessor to the extent that
the aggregate amount of the sums
<PAGE>
 
referred to in clauses (i) and (ii) above in the event of a release, and clauses
(i), (ii), (iii) and (iv) in a sale and/or disposition exceed the aggregate
rentals received by Lessor under such Schedule(s) for the respective remaining
Lease Term and/or aggregate proceeds received by Lessor in connection with the
disposition of the Equipment covered by such Schedule(s). Lessor's remedies
under this Lease shall not be deemed exclusive. Waiver of any default or breach
of this Lease shall not be construed as a waiver of subsequent or continuing
defaults or breaches.

17.  APPLICABLE LAW: THIS LEASE SHALL BE CONSTRUED IN ACCORDANCE WITH AND ALL
ACTIONS ARISING THEREUNDER, WHETHER BASED IN TORT AND/OR ON CONTRACT, OR
OTHERWISE, SHALL BE GOVERNED BY THE INTERNAL SUBSTANTIVE LAWS OF THE STATE OF
CALIFORNIA (EXCLUSIVE OF PRINCIPLES OF CONFLICT OF LAWS). If any party to this
Lease brings any action to enforce any of the terms, or to recover for any
breach, then the prevailing party shall be entitled to recover reasonable
attorneys' fees, costs of suit and collection from the other party. Lessee
agrees that any causes of action, disputes or demands whatsoever which relate to
or arise from this Lease shall, at the election of Lessor or its assignee, be
filed and conducted exclusively in the Courts of the State of California, County
of Orange, including but not limited to Superior or Municipal Court. Lessee
hereby voluntarily and irrevocably consents, and agrees to submit to the
personal jurisdiction of the Courts of the State of California, County of
Orange, and Lessee hereby waives its rights to a jury trial in any litigation
arising out of this Lease or Equipment.

18.  TRANSPORTATION; INSTALLATION/DEINSTALLATION; RETURN: All installation,
deinstallation, including packing materials and maintenance
certification/recertification by the Manufacturer/Vendor/Licensor,
transportation, rigging and drayage charges on delivery or redelivery of the
Equipment to and from Lessee shall be paid by Lessee. Upon expiration or
termination of the Lease for any item of Equipment, Lessee shall promptly return
the Equipment, freight prepaid, to a location in the continental United States
specified by Lessor, and shall pay to Lessor an amount equal to three percent
(3%) of the Equipment's original cost as an inspection, refurbishment and
restocking fee.

19.  FURTHER ASSURANCES: Lessee's signing of this Lease and each Schedule
attached thereto, or any Schedule later signed by Lessee that is to be attached
to this executed Lease, shall constitute an offer to Lessor to enter into the
Lease. In consideration of Lessor's time and efforts in reviewing and acting on
the offer, Lessee agrees that its offer shall be irrevocable unless and until
revoked by Lessee by providing twenty (20) business days' prior written notice
of such revocation to Lessor. Lessor's signing of this Lease and each Schedule
attached thereto, or any Schedule later signed by Lessee that is to be attached
to this executed Lease, shall constitute acceptance of Lessee's offer to enter
into the Lease. Upon acceptance of the Lease by Lessor and/or Lessor's
assignment of the Lease, Lessee shall execute such instruments and other
documents as Lessor deems necessary or desirable for confirmation, assignment
and assurance of performance by Lessee of its obligations hereunder or for
perfection of the Lease including, but not limited to, the filing of the Lease
or the filing of Uniform Commercial Code Financing Statements (which Lessee
agrees may be executed by Lessor on Lessee's behalf). Lessee will promptly
reimburse Lessor for any filing or recordation fees or expenses (including lien
search fees, legal fees and costs) incurred by Lessor in perfecting or
protecting its interests in the Equipment and under the Lease. Lessee further
authorizes Lessor
<PAGE>
 
to insert applicable dates as necessary to complete such supplemental
documentation. Prior to Lessor's acceptance of the Lease and during the Base
Lease Term or any extension period, Lessee shall also provide Lessor with all
credit information reasonably requested by Lessor, including but not limited to
comparative audited financial statements for the most current year and interim
reporting period. Lessee's failure to provide such information to Lessor shall
be an event of default under Section 15 herein. With respect to each Schedule
attached to this Lease, Lessor, in its sole and absolute discretion, may
require, as a condition of its approval, Lessee to provide Lessor with a lease
guarantee(s) in form and substance acceptable to Lessor (the "Lease
Guarantee(s)") from such individual(s), partner(s) and/or affiliated
corporation(s) who have substantial control over Lessee's operations. Lessee
agrees to procure such Lease Guarantee(s) promptly upon Lessor's written
request.

20.  REPRESENTATIONS AND WARRANTIES OF LESSEE: Lessee hereby represents,
warrants and covenants that with respect to this Lease or any attachment
executed thereunder, that: a) the execution, delivery and performance thereof by
Lessee has been duly authorized by Lessee; b) the individual(s) signing on
behalf of Lessee has authority to do so; c) any and all financial statements or
other information supplied to Lessor are accurate and complete and d) the
execution and/or performance thereof will not result in any default under or
breach of any judgment, order, law or regulation applicable to Lessee, or of any
provision of Lessee's articles of incorporation, bylaws, or any agreement to
which Lessee is a party.

21.  NOTICES: All notices to Lessor must be delivered in person to an officer of
Lessor or sent certified mail return receipt requested to Lessor at its address
shown above or at any later address last known to sender. All notices to Lessee
shall be in writing and shall be delivered by mail at its address shown herein
or at any later address last known to the sender.

22.  AGREEMENTS: All agreements and representations contained in this Lease, or
in any document or certificate in connection herewith, shall survive the
expiration or other termination of this Lease. Any provision of this Lease which
may be determined by competent authority to be unenforceable in any jurisdiction
shall be ineffective, as to such jurisdiction, to the extent of such
unenforceability without invalidating the remaining provisions hereof. To the
extent permitted by applicable law, Lessee hereby waives any provision of law
which renders any provision hereof prohibited or unenforceable. Time is of the
essence for this Lease.

23.  ASSIGNMENT: WITHOUT THE PRIOR WRITTEN CONSENT OF LESSOR, LESSEE SHALL NOT
ASSIGN THIS LEASE OR ITS INTEREST HEREUNDER IN ANY FORM OR MANNER. LESSOR MAY
WITHOUT NOTICE TO LESSEE ASSIGN ALL OR ANY PORTION OF ITS RIGHT, TITLE,
INTEREST, OR ANY OTHER RIGHTS IT MAY HAVE AS AN OWNER AND LESSOR OF THE
EQUIPMENT TO ANY ASSIGNEE ("ASSIGNEE"). LESSEE HEREBY CONSENTS TO SUCH
ASSIGNMENT AND FURTHER ACKNOWLEDGES AND AGREES THAT ASSIGNEE DOES NOT ASSUME ANY
OF THE OBLIGATIONS OF LESSOR HEREUNDER, AND, IF SO DIRECTED BY LESSOR, TO PAY
ALL ASSIGNED RENTALS DUE UNDER THE LEASE DIRECTLY TO ASSIGNEE UNCONDITIONALLY
WITHOUT OFFSET AND THAT SUCH RENTALS SHALL BE PAYABLE NOTWITHSTANDING ANY
DEFENSE OR COUNTERCLAIM,
<PAGE>
 
WHATSOEVER WHETHER BY REASON OF BREACH OF THE LEASE, THE EXERCISE OF ANY RIGHT
HEREUNDER, OR OTHERWISE, WHICH IT MAY OR MIGHT NOW OR HEREAFTER HAVE AS AGAINST
LESSOR (LESSEE RESERVING ITS RIGHT TO HAVE RECOURSE DIRECTLY AGAINST LESSOR ON
ACCOUNT OF ANY SUCH DEFENSE OR COUNTERCLAIM), AND THAT SUBJECT TO AND WITHOUT
IMPAIRMENT OF LESSEE'S LEASEHOLD RIGHTS IN AND TO THE EQUIPMENT, LESSEE SHALL
HOLD THE EQUIPMENT AND THE POSSESSION THEREOF FOR THE ASSIGNEE TO THE EXTENT OF
THE ASSIGNEE'S RIGHTS THEREIN, AND THAT ANY ASSIGNMENT BY LESSOR WOULD NOT
MATERIALLY ALTER THE DUTIES OF, NOR THE BURDEN OF RISK IMPOSED ON THE LESSEE.

24.  UNIFORM COMMERCIAL CODE ACKNOWLEDGMENT: This Lease is a "Finance Lease" as
defined in, and for the purpose only of Division 10 of the California Commercial
Code and not necessarily for any accounting purpose or otherwise. Lessee
acknowledges that Lessor has informed or advised Lessee, either previously or by

                          ASSET ACQUISITION AGREEMENT
                          ---------------------------

          ASSET ACQUISITION AGREEMENT (this "Agreement") dated as of December
30, 1996, between NETSOLVE, INCORPORATED, a Delaware corporation having an
office at 9130 Jollyville Road, Suite 200, Austin, Texas 78759 ("Seller"), and
INTERMEDIA COMMUNICATIONS INC., a Delaware corporation having an office at 3625
Queen Palm Drive, Tampa, Florida 33619 ("Buyer").

                                   RECITALS:

          Seller is engaged, among other things, in the provision of data
transport services through the use of both traditional private line circuits and
frame relay (but excluding the resale of AT&T Interspan frame relay services and
any related access lines or "tail circuits") (collectively, the "Transport
Business"), and including (where the same is provided to customers of the
Transport Business) the monitoring and troubleshooting of data communications
customer premise equipment such as channel banks, multiplexers, DSUs, CSUs, and
similar equipment attached to the data transport services (but excluding routers
or other equipment managed by Seller in its network management out-tasking
services), all of the above as set forth in Schedule 1.1(a) and collectively
referred to herein as the "Business".

          Seller desires to retain all of its assets and properties used in
connection with the portion of its business identified above as being excluded
from the definition of the Business, as well as any other service or other
portion of the Seller's business not included in the definition of the Business
(the "Retained Business") and to sell to Buyer and Buyer desires to acquire from
Seller, all right, title and interest of Seller in and to certain of the assets
and properties owned by Seller or used by Seller to conduct the Business, all
upon the terms and subject to conditions contained herein.

          NOW, THEREFORE, in consideration of the mutual promises and agreements
set forth herein, the parties hereto hereby agree as follows:

          1.   ACQUISITION
<PAGE>
 
          1.1.   ACQUIRED ASSETS.

          (a)  In consideration of the payment by Buyer of the relevant portion
of the Acquisition Price (as defined in Section 3.1 below), Seller hereby sells,
assigns, transfers, conveys and delivers to Buyer, and Buyer hereby purchases,
acquires and takes assignment and delivery of, all the right, title and interest
of Seller in and to the assets and properties of Seller listed on Schedule
1.1(a) (such assets and properties being referred to herein as the "Acquired
Assets").

          (b)  Except as set forth on Schedule 1.1(b), all of the Acquired
Assets are being sold, assigned, transferred, conveyed and delivered to Buyer
free and clear of all claims, encumbrances, security interests, mortgages,
pledges, restrictions, charges, or liens of any kind, including, without
limitation, tax liens ("Liens").

          1.2.   EXCLUDED ASSETS.  Notwithstanding the foregoing, Seller is not
selling, assigning, transferring, conveying or delivering, and Buyer is not
purchasing pursuant to this Agreement, and the term "Acquired Assets" does not
include, any assets or properties of Seller not expressly and specifically
included in the list of Acquired Assets (the "Excluded Assets").

          2.   LIMITED ASSUMPTION OF LIABILITIES

          2.1.   ASSUMPTION OF LIABILITIES.  Except as expressly provided
herein, Buyer does not assume or agree to pay, perform or discharge, any debts,
liabilities, obligations, claims, expenses, taxes, contracts, accounts payable,
or commitments of any kind, character or description, whether accrued or fixed,
absolute or contingent, matured or unmatured or determined or undetermined
(collectively, "Liabilities") of Seller.  Subject to the terms, conditions,
representations and warranties contained herein, Buyer hereby assumes and agrees
to fully and completely pay, perform and discharge when due all Liabilities
incurred and arising after the date hereof with respect to the Acquired Assets
and its provision, following the date hereof, of the Business (the "Assumed
Liabilities") and no other Liabilities of Seller.

          2.2.   EXCLUDED LIABILITIES.  Except for the Assumed Liabilities, and
regardless of whether any of the following may 

                                       2
<PAGE>
 
be disclosed to Buyer pursuant to Section 4 hereof or otherwise, or whether
Buyer has knowledge of same, Buyer does not assume, and shall have no liability
for any Liabilities arising out of any act or omission occurring prior to the
date hereof (the "Excluded Liabilities") including, without limitation, any
Liability of Seller relating to or arising from: (i) the breach of Seller's
obligations under the leases, contracts and agreements assigned to Buyer; (ii)
any infringement by Seller on the rights of others in connection with the
Business; (iii) taxes, including, without limitation, any social security taxes

including any thereof that may be due in connection with the transactions
contemplated hereby; (iv) any accrued but unpaid payroll, severance, bonus,
holiday and/or vacation obligations to employees of Seller; (v) any damages,
fines, interest or penalties assessed by any federal, state, county, city or

long-term debts, payables or amounts owing to any of Seller's officers,

Seller retains, and shall fully and completely pay, perform and discharge when

          3.   ACQUISITION PRICE

          3.1.   ACQUISITION PRICE; ALLOCATION OF ACQUISITION PRICE.  (a)
Subject to the adjustments set forth in Section 3.2, the acquisition price for
the Acquired Assets shall be $9,280,000 and the acquisition price for the
covenants contained in Section 7.2 shall be $3,000,000 (together, the
"Acquisition Price"). The Acquisition Price is hereby being paid by delivery of
cash in the amount of $10,280,000 to Seller and cash in the amount of $2,000,000
to Kronish, Lieb, Weiner & Hellman LLP (the "Escrow Agent") to be held in escrow
by the Escrow Agent in accordance with the terms and provisions of the Escrow
Agreement (the "Escrow Agreement") being executed on the date hereof among
Buyer, Seller and the Escrow Agent. The funds being held in such escrow are
hereafter referred to as the "Escrow Fund".

                                       3
<PAGE>
 
          (b)  Not later than 30 business days after the date hereof, Buyer
shall deliver to Seller a statement setting forth an allocation of the sum of
the Acquisition Price and the Assumed Liabilities among the Acquired Assets in
accordance with Exhibit A.  Any subsequent adjustments to the sum of the
Acquisition Price and Assumed Liabilities shall be reflected in the allocation
hereunder in a manner consistent with Treasury Regulation (S) 1.1060-1T(f).  For
all tax purposes, Buyer and Seller agree to report the transactions contemplated
in this Agreement in a manner consistent with the terms of this Agreement,
including the allocation under Exhibit A, and that none of them will take any
position inconsistent therewith in any tax return, in any refund claim, in any
litigation, or otherwise.

          3.2.   ADJUSTMENT TO THE ACQUISITION PRICE.  The Acquisition Price
shall be subject to the following adjustment for loss of customers:

          (a)  Set forth on Exhibit B are the customers of the Business for the
month November 1996 (the "Base Month") and the aggregate amount billed to those
customers in the Base Month. The parties agree that the aggregate amount billed
to the customers listed on Exhibit B in the Base Month is equal to $753,743 (the
"Base Month Billings").  As promptly as practicable after November 30, 1997, but
in no event later than January 15, 1998, Buyer shall deliver to Seller a written
statement (the "Buyer's Statement") setting forth the average monthly amount
billed to the customers listed on Exhibit B over the 12 full months commencing
December 1, 1996 and ending November 30, 1997 (the "Average Monthly Billings")
and the amount billed to each customer for each month upon which the Average
Monthly Billings were calculated.  The accuracy of the information contained
therein shall be certified to by the Chief Financial Officer (or other
appropriate officer) of Buyer.  In the event Buyer shall fail to deliver to
Seller the Buyer's Statement by January 15, 1998, Seller shall be entitled to
have all amounts held in the Escrow Fund released to Seller.

          (b)  Seller may verify any amounts set forth on the Buyer's Statement;
provided, however, that Seller shall have notified Buyer in writing of its
intent to do so within 30 days after delivery of the Buyer's Statement to
Seller.  Buyer shall provide Seller reasonable access to Buyer's books and
records 

                                       4
<PAGE>
 
during the 30-day period following any such notice by Seller as is necessary for
Seller to determine the accuracy of the Buyer's Statement. In the event of such
a dispute, Buyer and Seller shall attempt to reconcile their differences, and
any resolution by them as to any disputed amounts shall be final, binding and
conclusive on the parties hereto. If Buyer and Seller are unable to reach a
resolution within 30 days after receipt by Buyer of Seller's written notice of
its intent to verify the Buyer's Statement, Buyer and Seller shall submit the
items in dispute for resolution to an internationally recognized independent
accounting firm that is independent of Buyer and Seller (such accounting firm
being referred to herein as the "Independent Accounting Firm"), which shall,
within 30 business days after such submission, determine and report to Seller
and Buyer upon such remaining disputed items, and such report shall be final,
binding and conclusive on the parties hereto. The fees and disbursements of the
Independent Accounting Firm shall be allocated between Seller and Buyer in the
same proportion that the aggregate amount of such disputed items so
unsuccessfully disputed by each such party (as finally determined by the
Independent Accounting Firm) bears to the total amount of disputed items so
submitted.

          (c)  The Buyer's Statement shall be deemed final for the purposes of
this Section 3.2 upon the earliest of (i) Seller's notification to Buyer that it
does not intend to verify the Buyer's Statement, (ii) the failure of Seller to
notify Buyer of its intent to verify the Buyer's Statement within 30 days after
receipt by Seller of the Buyer's Statement, (iii) the resolution of all
disputes, pursuant to Section 3.2(b), by Seller and Buyer and (iv) the
resolution of all disputes, pursuant to Section 3.2(b), by the Independent
Accounting Firm.  Promptly after the Buyer's Statement is deemed final, an
adjustment payment shall be made as follows: in the event the Average Monthly
Billings (as specified in the final Buyer's Statement) shall be less than 80% of
Base Month Billings, then the Escrow Agent shall promptly and in accordance with
the terms of the Escrow Agreement deliver to Buyer from the Escrow Fund an
amount equal to the product of the amount of such deficiency multiplied by 8.4.
Buyer's recourse against Seller under this Section 3.2(c) shall be limited to
the Escrow Fund, even if cash in such Escrow Fund shall be insufficient to cover
the amount of such deficiency.

                                       5
<PAGE>
 
          (d)  Notwithstanding anything in this Section 3.2 to the contrary, in
the event any customer listed on Exhibit B becomes a frame relay customer of
Buyer during the 12 month period ending November 30, 1997, Seller shall have the
option to delete that customer and its billings (or the portion of such
customer's network as shall have been converted to frame relay if less than all
of such customer's network shall have been converted) from Exhibit B and, if
Seller exercises such option, the Base Month Billings and the Average Monthly
Billings shall be recomputed without regard to such customer or its affected
billings (it being understood that if Seller shall not exercise such option the
billings to such customer as a frame relay customer shall be included in
determining the Average Monthly Billings).  In addition, the parties expressly
agree that billings for local exchange carrier tail circuits are not included in
Base Month Billings and shall not be included in Average Monthly Billings.

          3.3.   APPORTIONMENT.  All income and expenses pertaining to the
Business, including, without limitation, all prepaid sums and fees, service
charges, advertising, rental charges, utility charges, payments under assigned
agreements, and accrued and prepaid expenses, shall be prorated between Buyer
and Seller as of December 1, 1996 so that the Seller shall receive all revenues
and shall be responsible for all expenses and liabilities allocable to the
period prior to December 1, 1996 and Buyer shall receive all revenues and shall
be responsible for all expenses and liabilities allocable to the period
beginning on and continuing after December 1, 1996.  Buyer and Seller shall
cooperate with each other in calculating all such prorated items and shall make
a payment one to the other, as appropriate, within sixty (60) days of the
Closing of the net amount of such prorated items.

          4.   REPRESENTATIONS AND WARRANTIES OF SELLER.

          Seller hereby represents and warrants to Buyer as follows (all

Assets, or the Business involving claims in excess of $100,000, or which

are no facts or circumstances that are reasonably likely to give rise to any of
the foregoing.

                                       10

thereby.  Each of this Agreement, the Escrow Agreement and the Management
Agreement has been duly executed and delivered by Buyer and (assuming due
authorization, execution and delivery by the other parties hereto and thereto)

Buyer in accordance with its terms, subject to the effects of bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium and other similar
laws relating to or affecting creditors' rights generally and general equitable
principles (whether considered in a proceeding in equity or at law).

          5.3.   NON-CONTRAVENTION.  None of the execution and delivery of this

Management Agreement by Buyer, the performance of its obligations hereunder and
thereunder, or the consummation by Buyer of the transactions contemplated hereby
and thereby will constitute a violation of, or be in conflict with, Buyer's
Certificate of Incorporation and By-laws or will, with or without notice, the
passage of time or both, constitute a material breach or violation of, be in
conflict with, constitute or create a material default under or result in the
creation or imposition of any Liens upon any property of Buyer pursuant to (a)
any contract, indenture, agreement, instrument, mortgage, lease or commitment to
which Buyer is a party or by which any of its properties are bound, or to which
Buyer is subject or (b) any law or statute or any judgment, decree, order,
regulation or rule of any court or governmental or regulatory authority relating
to Buyer.

          5.4.   LITIGATION, ETC.  There are no actions, suits, proceedings or
investigations pending or threatened against Buyer which question the validity
of this Agreement or challenge any of the transactions contemplated hereby and,
to the best knowledge of Buyer, there are no facts or circumstances that are
reasonably likely to give rise to any of the foregoing.

          5.5.   BROKERS, FINDERS, ETC.   Other than for Bear, Stearn's & Co.,
Inc. ("Bear"), all negotiations relating to this Agreement and the transactions

          (i)    the breach of any representation, warranty, covenant or
agreement made by Seller contained in this Agreement, the Escrow Agreement or
the Management Agreement; or

          (ii)   any claim or cause of action of any third party (including,

city or municipal government or any governmental agency or authority to the
extent arising out of any action, inaction, event, condition, Liability or
obligation of Seller occurring or existing prior to the date hereof (regardless
of whether or not referred to on a Schedule to this Agreement or otherwise
disclosed or known to Buyer as of the date hereof); or

          (iv)   failure to pay, perform or discharge when due any Excluded
Liability; or

          (v)    the operation or conduct of Seller's businesses, including,
without limitation, the operation or conduct of the Business through the date

                                       14
<PAGE>
 
          (b)    Buyer agrees to defend, indemnify and hold harmless Seller, any
subsidiary or affiliate thereof and any of their officers, directors,
controlling persons, employees, agents, successors and assigns (the "Indemnified
Seller Group") from and against any and all Liabilities (other than the Excluded
Liabilities), losses, damages, claims, costs, expenses, judgments, interest and
penalties (including, without limitation, attorneys' and accountants' reasonable
fees and disbursements incurred by the Indemnified Seller Group in any action or
proceeding between Buyer and the Indemnified Seller Group or between the
Indemnified Seller Group and any third party or otherwise) incurred as a result
of, arising out of or resulting from:

          (i)    the breach of any representation, warranty, covenant or
agreement made by Buyer contained in this Agreement, the Escrow Agreement or the
Management Agreement; or

          (ii)   the failure on the part of Buyer to pay, perform and discharge
when due the Assumed Liabilities; or

          (iii)  the operation or conduct of the Business by Buyer from and
after the date hereof.

          6.2.   SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  The
representations and warranties made by Buyer and Seller are made as of the date
hereof and not on a continuous basis.  However, for a period of 18 months after
the date hereof, claims, actions, or causes of action may be made with respect
to the breach, untruth or inaccuracy thereof.  All representations and
warranties made by or on behalf of Seller in this Agreement shall be deemed to
have been relied upon by Buyer (notwithstanding any investigation by Buyer).

          6.3.   NOTICE OF CLAIMS.  An indemnified party shall give prompt
written notice to the indemnifying party of any claim against the indemnified
party which might give rise to a claim by the indemnified party against the
indemnifying party under the indemnification provisions contained herein,
stating the nature and basis of the claim and the actual or estimated amount
thereof, provided, however, that failure to give such notice will not effect the
obligation of the indemnifying party to provide indemnification in accordance
with the terms of Section 6.1

                                       15
<PAGE>
 
unless, and only to the extent that, the indemnifying party is actually
prejudiced thereby. In the event that any action, suit or proceeding is brought
against any indemnified party with respect to which the indemnifying party may
have liability under the indemnification provisions contained herein, the
indemnifying party shall, upon written acknowledgement by the indemnifying party
that such action, suit or proceeding is an indemnifiable loss pursuant to
Section 6.1, have the right, at the cost and expense of the indemnifying party,
to defend such action in the name and on behalf of the indemnified party (using
counsel reasonably satisfactory to the indemnified party), and, in connection
with any such action, the indemnified party and the indemnifying party agree to
render to each other such assistance as may reasonably be required in order to
ensure proper and adequate defense of such action, provided, however, that an
indemnified party shall have the right to retain its own counsel, with fees and
expenses paid by the indemnifying party, if representation of such indemnified
party by counsel retained by the indemnifying party would be inappropriate
because of an actual conflict of interest between such indemnified party and the
indemnifying party in the particular matter at hand. If the indemnifying party
shall fail to defend such action, suit or proceeding, then the indemnified party
shall have the right to defend such action without prejudice to its rights to
indemnification under Section 6.1 and, in connection therewith, the indemnified
party and the indemnifying party agree to render to each other such assistance
as may reasonably be required in an effort to provide for the appropriate
defense of such action. Neither the indemnified party nor the indemnifying party
shall make any settlement of any claim which might give rise to liability of the
indemnifying party under the indemnification provisions contained herein without
the written consent of each party, which consent shall not be unreasonably
withheld, delayed or conditioned.

          7.   ADDITIONAL AGREEMENTS

          7.1.   CONFIDENTIALITY.  Except as may be necessary in connection with
Seller's performance of the Management Agreement, for a period of three years
from the date hereof, Seller shall, and shall cause its employees, agents,
representatives, affiliates, officers and directors to:

                                       16
<PAGE>
 
          (a)  treat and hold as confidential all confidential information
relating to the Business, including, without limitation, any information
relating to trade secrets, customer and supplier lists, pricing and marketing
plans and details of customer contracts, provided, however, that the provisions
of this Section 7.1 shall not apply to any information that is or becomes
generally available to the public other than as a result of an impermissible
disclosure by Seller or its employees, agents, representatives, affiliates,
officers and directors; and

          (b)  promptly furnish to Buyer any and all copies (in whatever form or
medium) of such confidential information in its possession.

          7.2.   NON-COMPETE.  In consideration of the relevant portion of the
Acquisition Price, Seller agrees that for a period of five years from the date
hereof, Seller shall not directly or through any affiliate conduct any Transport
Business that is or may become competitive with Buyer in the Business anywhere
in the United States; provided, that the foregoing shall not prohibit Seller
from carrying on its Retained Business or any other business (other than the
Transport Business) and providing all of its services (other than the Transport
Business), even if such services and business is provided to actual or potential
competitors of Buyer.  Notwithstanding the foregoing, if, within five years from
the date hereof, Seller receives an offer to purchase all or a substantial part
of the Retained Business (the "Offered Business") from a third party, Seller
shall promptly notify Buyer of such offer (the "Offer Notice"), which Offer
Notice shall include a reasonable description of the material terms of the offer
from such third party.  Buyer and Seller shall mutually determine whether such
third party is a direct competitor of Buyer in the Transport Business.  In the
event Buyer and Seller shall agree that such third party is a direct competitor
of Buyer in the Transport Business, Buyer may submit an offer for the purchase
of the Offered Business within 10 business days after reaching such agreement.
Seller agrees that it will consider, in good faith, any such offer of Buyer;
however, Seller shall in no way be required to accept Buyer's offer, or be
prohibited or limited in any way from consummating a transaction for the sale of
the Offered Business with any third party if, for any reason, Seller deems it to
be in its best interest to do so.  Seller shall not enter into any agreement or

                                       17
<PAGE>
 
arrangement with any such third party which would preclude Seller from providing
the Offer Notice to Buyer or accepting Buyer's offer prior to Seller's good
faith determination that Seller does not wish to accept Buyer's offer.  Buyer
shall keep confidential the fact that it has received an Offer Notice and the
terms of the Offer Notice.

          7.3.   EMPLOYEES.  Buyer shall be permitted to discuss potential
employment arrangements, on terms at least as favorable as their current
employment terms with Seller, with those employees identified with an asterisk
on Schedule 4.11; provided, that  prior to Buyer offering employment to any of
the employees identified with an asterisk on Schedule 4.11 Seller and Buyer
shall negotiate and agree upon the impact the hiring of such employee by Buyer
may have on the ability of Seller to perform its obligations, appropriate relief
for Seller and any corresponding reduction for the fees paid to Seller under the
Management Agreement.  Buyer shall not, for a period of one year after the date
hereof, directly or indirectly through an affiliate, (i) offer employment to any
other employee of Seller (whether listed on Schedule 4.11 or subsequently hired
by Seller), (ii) induce or seek to influence any other employee of Seller to
leave his or her employ or terminate his or her consultancy with Seller or (iii)
aid any party in any attempt to hire any other employee of Seller; provided,
that Buyer shall have the right to demonstrate to Seller certain areas of need
and, with the prior written consent of Seller (which consent may be granted or
withheld in the sole discretion of Seller for any reason), to hire other
employees of Seller to fill positions in those areas of need (it being
understood that in granting such consent Seller and Buyer may negotiate and
agree upon the impact the hiring of such employee by Buyer may have on the
ability of Seller to perform its obligations, appropriate relief for Seller and
any corresponding reduction for the fees paid to Seller under the Management
Agreement).

          7.4.   SUBCONTRACTS.  Seller hereby agrees to use all reasonable
efforts to obtain any consents necessary to assign or otherwise transfer the
Material Contracts to Buyer. In the event that any consent required with respect
to any Material Contract cannot be obtained, upon the request of Buyer, Seller
hereby agrees to subcontract or sublease all of its obligations to perform under
such contract to Buyer. Buyer shall fully and 

                                       18
<PAGE>
 
completely indemnify and hold Seller harmless from and against any and all
claims arising our of Buyer's performance or failure to perform thereunder. The
cost of performing each such subcontract or sublease shall be borne by Buyer.
Seller will deliver to Buyer all revenues earned under each such Material
Contract. Buyer shall cooperate with Seller so as to permit Seller to be
relieved of all Assumed Liabilities under such Material Contracts. Buyer shall
lease to Seller all equipment included in the Acquired Assets required by Seller
to perform its obligations under this Section 7.4 for one dollar per month.

          7.5.   TAX RECORDS.  For income tax purposes, Seller shall, upon
reasonable request of Buyer, allow Buyer access for six years from the date
hereof to existing records relating to the Business that are in Seller's
possession and Seller shall use all reasonable efforts to maintain such records
for six years unless specifically authorized by Buyer to the contrary.  In the
event Buyer shall obtain access to any records, documents or information of any
kind of Seller which are not related to the Business, Buyer shall, and shall
cause its employees, agents, representatives, affiliates, officers and directors
to, maintain all such records, documents and information in strict confidence
and shall not disclose the same to any third party or use any of such records,
documents or information for any purpose which would be reasonably likely to
adversely affect Seller. Notwithstanding the foregoing, the confidentiality
provisions of this paragraph shall not apply to records, documents or
information which (i) is or becomes generally available to the public other than
as a result of a disclosure by Buyer or its employees, agents, representatives,
affiliates, officers and directors, (ii) was available to Buyer on a
nonconfidential basis prior to its disclosure by Seller (except that any such
documents marked to indicate their confidential nature are covered herein) or
(iii) becomes available to Buyer on a nonconfidential basis from a person other
than Seller or any of its employees, agents, representatives, affiliates,
officers and directors who, to Buyer's knowledge, is not bound by a
confidentiality agreement with Seller or otherwise prohibited from transmitting
the information to Buyer.

          7.6.   MANAGEMENT AGREEMENT.  Buyer and Seller shall enter into a
management agreement (the "Management Agreement"), substantially in the form
attached hereto as Exhibit C, whereby 

                                       19
<PAGE>
 
Seller will manage the Acquired Assets and the customers of the Business for a
period of 12 months from the date hereof.

          7.7.   INTRASTATE SERVICES.  Buyer and Seller agree that Seller shall
continue after the date hereof to provide those services necessary for the
origination and termination of private line services in California using the
tariffed services of local exchange carriers for the Seller's existing customers
and for any new customers directed to it by Buyer (except that Buyer shall agree
to pay Seller's standard coordination fees for such services provided to new
customers).  The provision of such services shall be for Seller's account and
the Seller shall collect the proceeds from these services provided by Seller and
pay any expenses incurred to provide such services.  Seller further agrees that
any invoice or statement sent to any customer of the Business relating to
services provided by Seller shall refer to Seller as the provider of such
services and shall refer to Buyer where and as appropriate and when requested by
Buyer (but subject to Buyer's prior approval).  Buyer hereby agrees to provide
to Seller, on a non-exclusive basis, the use of those Acquired Assets as are
necessary to enable Seller to perform Seller's obligations hereunder for a
monthly charge equal to one dollar.  The provision of such services and the use
of the Acquired Assets pursuant to this Section 7.7 may be terminated by Buyer
at any time by written notice to Seller, and by Seller on the earlier of the
date of twelve months from the date hereof or the approval of the transfer by
the California Public Utility Commission.

          7.8.   PRE-CLOSING OBLIGATIONS.  Except for revenues and expenses
relating to the origination and termination of  private line services in the
State of California pursuant to  the arrangements set forth in Section 7.7 (the
"Excluded Revenues and Expenses"), Buyer and Seller agree that during the period
from December 1, 1996 through the date hereof ("Pre-Closing Period") Seller
conducted the Business for the account of Buyer and pursuant to the control and
discretion of Buyer.  In the event that the aggregate gross revenues earned by
the Business during the Pre-Closing Period ("Revenues") exceed aggregate
expenses incurred by the Business during the Pre-Closing Period ("Expenses"),
Seller shall pay the difference to Buyer.  In the event that Expenses exceed
Revenues, Buyer shall pay the difference to Seller.  Notwithstanding the
preceding two 

                                       20
<PAGE>
 
sentences, if the difference to be paid pursuant to this Section 7.8 shall be
less than $1,000, Buyer and Seller agree that such difference shall not be paid.
Revenues and Expenses shall be calculated without regard to the Excluded
Revenues and Expenses and in accordance with Seller's normal accounting
practices. All payments due pursuant to this Section 7.8 shall be paid by wire
transfer in immediately available funds not later than five business days after
the amount of Revenues and Expenses shall have been agreed to in writing by
Buyer and Seller. Buyer and Seller shall cooperate with each other and shall use
all reasonable good faith efforts to reach such agreement.

          7.9.   BANDWIDTH AVAILABILITY AND EQUIPMENT PLACEMENT. Buyer shall
make available to Seller throughout the term of the Management Agreement,
without charge to Seller, adequate bandwidth over the network purchased pursuant
to this Agreement for use as management channels for provision by Seller of
Seller's network management services to Seller's current customers serviced over
the network purchased pursuant to this Agreement. Buyer shall also permit Seller
to locate Seller's currently existing equipment used in connection with its
network management services at the facilities purchased by Buyer pursuant to
this Agreement throughout the term of the Management Agreement, without charge
to Seller.

          7.10.  COMPLIANCE WITH LAWS AND PERMITS.  From and after the date
hereof, Buyer shall conduct the Business, in all material respects, in
accordance with all laws and statutes and rules, regulations, judgments, orders
or decrees of any court or governmental or regulatory authority applicable to
Buyer or the Business. In addition, from and after the date hereof, Buyer shall
comply, in all material respects, with all permits, licenses, franchises,
orders, certificates and approvals of any federal, state or local regulatory or
administrative agency or court relating to the Business.

                  SERIES B PREFERRED STOCK PURCHASE AGREEMENT


     THIS SERIES B PREFERRED STOCK PURCHASE AGREEMENT is made as of the 19th day
of October, 1992, by and among SOUTHWEST NETWORK SERVICES, INC., a Delaware
corporation (the "Company"), certain persons and entities among those listed on
Schedule A hereto, each of whom is herein referred to individually as a "Prior
Investor" and collectively as the "Prior Investors" and each of whom is a party
to that certain Series A Preferred Stock Purchase Agreement of the Company dated
as of April 10, 1991 (the "Prior Agreement") who, in the aggregate hold the
number of shares of capital stock of the Company required to amend the various
provisions of the Prior Agreement, in accordance with Section 10.10 thereof and
the persons and entities listed on Schedule B hereto, each of whom is herein
referred to individually as a "New Investor" and collectively as the "New
Investors" (the Prior Investors and the New Investors are sometimes referred to
herein individually as an "Investor" and collectively as the "Investors").

                                  WITNESSETH:

     The Company and certain of the Prior Investors previously entered into the
Prior Agreement pursuant to which, among other things, the Company sold to such
Prior Investors and the Prior Investors purchased from the Company shares of the
Company's Series A Preferred Stock.

     Pursuant to that certain Secured Demand Note Agreement of the Company dated
as of March 31, 1992, as amended and restated (the "Note Agreement"), the
Company borrowed from the Lenders under the Note Agreement (some of whom are
also Prior Investors) an aggregate principal amount of $3,095,686.63 and, as
evidence of the Company's indebtedness to each of such Lenders, executed and
delivered to each of such Lenders the Company's Secured Demand Promissory Notes
(the "Notes").

     The Company now desires to exchange the Notes previously issued to the

materially adverse change in the assets, condition, affairs or prospects of the
Company, financially or otherwise, or any change in the current equity ownership
of the Company, nor is the Company aware that there is any basis for the
foregoing.  The foregoing includes, without limitation, actions pending or
threatened (or any basis therefor known to the Company) involving the prior

Company's business of any information or techniques allegedly proprietary to any
of their former employers, or their obligations under any agreements with prior

           (collectively, the "Financial Statements") attached hereto as Exhibit
           "C". The Financial Statements have been prepared in accordance with
           generally accepted accounting principles, consistently applied

           (i)   any material change in the assets, liabilities, financial
                 condition or operating results of the Company from that
                 reflected in the Financial Statements, except changes in the
                 ordinary course of business which have not been, individually
                 or in the aggregate, materially adverse;

           (ii)  any material damage, destruction or loss of, or to, assets of
                 the Company, whether or not covered by insurance;

           (iii) any waiver by the Company of a valuable right or of a material
                 debt owed to it;

           (iv)  any declaration, authorization or payment of any dividend or
                 other distribution of the assets of the Company, or any
                 agreement to declare, authorize or pay any said dividend or
                 distribution; or

           (v)   any material change or amendment to a material contract or
                 arrangement by which the Company or any of its assets or
                 properties is bound or subject.

     (b)   To the Company's knowledge, there has not been since August 31, 1992
           any event or condition of any character which would materially and
           adversely affect the assets, properties, financial condition,
           operating results or business of the Company.

     2.16  Employee Benefits Plans.  Except for the Profit Sharing 401(k) Plan
and the Section 125 Cafeteria Plan of the Company (collectively, the "Plans")
described in the summaries of such Plans attached hereto as Exhibits "D-1" and
"D-2", respectively, the Company does not 

                                      -7-
<PAGE>
 
have any employee benefit plan as defined in the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"). The Company has fulfilled its
obligations, if any, under the minimum funding standards of ERISA and the
Internal Revenue Code of 1986, as amended, and the rules and regulations
promulgated thereunder (the "Code"), with respect to the Plans and is in
compliance in all material respects with the presently applicable provisions of
ERISA and the Code, and has not incurred any liability to the Pension Benefit
Guaranty Corporation or the Plan under Title IV of ERISA which is material to
the Company.

summary of all meetings of directors and stockholders since the time of
incorporation and reflects all transactions referred to in such minutes
accurately in all material respects.

     2.18  Real Property Holding Corporation.  The Company is not a "United
States real property holding corporation," as that term is defined in Section
897(c)(2) of the Code and Treasury Regulation Section 1.897-2(b).  If at any
time in the future the Company shall become a "United States real property
holding corporation", the Company shall notify each foreign investor of such
event as promptly as practicable.  Within thirty (30) days after receipt of a
request from a foreign investor, the Company shall prepare and deliver to such
foreign investor the statement required under Treasury Regulation Section 1.897-
2(h) and, subject to the succeeding sentence, either or both of the following
documents:  (i) an affidavit in conformance with the requirements of Section
1445(b)(3) of the Code, or (ii) a notarized statement, executed by an officer
having actual knowledge of the facts, that the shares of Company stock held by
such foreign investor are of a class that is regularly traded on an established
securities market, within the meaning of Section 1445(b)(6) of the Code.  If the
Company is unable to provide either of the documents described in (i) or (ii)
above upon request, it shall promptly, and in any event within thirty (30) days,
notify such foreign investor in writing of the reason for such inability.
Finally, upon the request of a foreign investor and without regard to whether
either document described in (i) or (ii) above has been requested, the Company
shall reasonably cooperate with the efforts of such foreign investor to obtain a
"qualifying statement" within the meaning of Section 1445(b)(4) of the Code or
such other documents as would exclude a transferee of a foreign investor's
interest from withholding of income tax imposed pursuant to Section 897(a) of
the Code.

     3.    Additional Representations, Warranties and Covenants of the Company.
The Company represents and warrants to, and covenants with, the Investors, and
each of them, as follows:

     3.1   Claims Re: Employment.  Except as set forth on Schedule 2.7 hereof,

current employee with respect to the continued employment by the Company of any
current employee under the terms of any employment contract, covenant not to
compete, patent disclosure agreement or otherwise.  Except as set forth on
Schedule 2.7 hereof, no litigation is pending or threatened against any current
employee or the Company relating to the employee's relationship with any former
employer. Except as set forth on Schedule 2.7 hereof, no former or existing
employee of the Company has 

                                      -8-
<PAGE>
 
asserted any claim against the Company arising out of any actual or alleged
breach of any actual or alleged employment contract with the Company.

     3.2   Claims Re: Information.  Except as set forth on Schedule 2.7 hereof,
no person or entity is known to have any claim against the Company or any
current employee with respect to the use of any proprietary information, trade
secrets, patents, formulae or other intangible property rights by the Company or
any current employee under the terms of any agreement, instrument or law.

     3.3   Employee Shareholder Agreements.  All employee stockholders of the
Company have entered into, and until such time as the Company may complete its
initial sale of its Common Stock pursuant to a Registration Statement on Form S-
1, or its equivalent, under the Securities Act of 1933, as amended (the "Act"),
which results in aggregate cash proceeds to the Company of in excess of
$10,000,000 and the public offering price of which is not less than $6.00 per
share (adjusted to reflect subsequent changes in the capitalization of the
Company) ("Qualified IPO"), each person who is or who shall become an employee-
stockholder of the Company shall enter into, a Shareholder's Agreement with the
Company in the form attached hereto as Exhibit "E" or such other form as the
board of directors of the Company may approve from time to time.

     3.4   Proprietary Information and Inventions Agreement.  All present
employees have, and at least until such time as the Company may complete its
Qualified IPO, all future employees shall, as a condition to the commencement
and continuation of their employment with the Company, enter into a Proprietary
Information and Inventions Agreement with the Company, substantially in the form
attached hereto as Exhibit "F" or such other form as the board of directors of
the Company may approve from time to time.

     3.5   Claims Re: Prior Employers.  To the Company's knowledge, and except
as set forth on Schedule 2.7 hereof, no employee of the Company has any duty or
obligation to perform any service for any prior employer of such employee, other
than in connection with the application for, or renewal or prosecution of,
patents or other proprietary information rights.

     4.    Representations and Warranties of the New Investors.  Each New
Investor hereby represents and warrants that:

     4.1   Authorization.  This Agreement constitutes its valid and legally
binding obligation, enforceable in accordance with its terms.

     4.2   Purchase Entirely for Own Account.  It is acquiring the Series B
Preferred Stock and the Warrants solely for investment purposes and not for sale
or with a view to distribution of all or any part of such Series B Preferred
Stock or Warrants or the Common Stock issuable upon the conversion or exercise
thereof.

     4.3   Disclosure of Information.  It believes it has received all the
information it considers necessary or appropriate for deciding whether to
purchase the Series B Preferred Stock and the Warrants.  Each New Investor
further represents that it has had an opportunity to ask 

                                      -9-
<PAGE>
 
questions and receive answers from the Company regarding the terms and
conditions of the investment contemplated hereby. The foregoing, however, does
not limit or modify the representations and warranties of the Company in
Sections 2 and 3 of this Agreement.

     4.4   Investment Experience.  Each New Investor is an accredited investor
within the meaning of Regulation D under the Act and an investor in securities
of companies in the development stage and acknowledges that it is able to fend
for itself, can bear the economic risk of its investment for an indefinite
period of time and has such knowledge and experience in financial or business
matters that it is capable of evaluating the merits and risks of the investment
contemplated hereby and to protect itself in connection with such investment.
If other than an individual, each New Investor also represents that it has not
been organized or reorganized for the specific purpose of making the investment
contemplated hereby.

     4.5   Restricted Securities.  It understands that the Series B Preferred
Stock and the Warrants, as well as the Common Stock issuable upon conversion or
exercise thereof are characterized as "restricted securities" under the federal
securities laws inasmuch as they are being acquired from the Company in a
transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under
the Act only in certain limited circumstances.  In this connection, each New
Investor represents that it is familiar with SEC Rule 144, as presently in
effect, and understands the resale limitations imposed thereby and by the Act.

     4.6   Further Limitations on Disposition.  Without in any way limiting the
representations set forth above, each New Investor further agrees not to make
any disposition of all or any portion of the Series B Preferred Stock or
Warrants (or the Common Stock issuable upon the conversion or exercise thereof)
unless and until:

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

     (b)   (i) Such New Investor shall have notified the Company of the proposed
           disposition and shall have furnished the Company with a detailed
           statement of the circumstances surrounding the proposed disposition,
           and (ii) if reasonably requested by the Company, such New Investor
           shall have furnished the Company with an opinion of counsel,
           reasonably satisfactory to the Company, that such disposition will
           not require registration of such shares under the Act. It is agreed
           that the Company will not require opinions of counsel for
           transactions made pursuant to Rule 144 except in unusual
           circumstances.

     (c)   Notwithstanding the provisions of paragraphs (a) and (b) above, no
           such registration statement or opinion of counsel shall be necessary
           for a transfer: (i) by a New Investor which is a partnership to a
           partner of such partnership or a retired partner of such partnership
           who retires after the date hereof, or to the

                                      -10-
<PAGE>
 
           estate of any such partner or retired partner, where no consideration
           is paid by the partner or retired partner, if the transferee agrees
           in writing to be subject to the terms hereof to the same extent as if
           he were an original New Investor hereunder; or (ii) by a New Investor
           which is a corporation to an affiliate thereof which is directly or
           indirectly owned by the same corporate parent as such New Investor.

     4.7   Legend.  It is understood that the certificates evidencing the Series
B Preferred Stock and the Warrants (and the Common Stock issuable upon
conversion or exercise thereof) may, in addition to any legends required by any
state securities laws, bear the following legend:

           "These securities have not been registered under the Securities Act
           of 1933.  They may not be sold, offered for sale, pledged or
           hypothecated in the absence of a registration statement in effect
           with respect to the securities under such Act or an opinion of
           counsel reasonably satisfactory to the Corporation that such
           registration is not required or unless sold pursuant to Rule 144
           under such Act or otherwise pursuant to the terms of that certain
           Series B Preferred Stock Purchase Agreement dated as of October 19,
           1992.  These securities must also be voted in accordance with such
           Agreement.  Copies of such Agreement may be obtained upon written
           request to the Secretary of the Corporation."

     5.    Conditions of Investors' Obligations at Closing.  The obligations of
each New Investor under subsection 1.1(c) of this Agreement are subject to the
fulfillment on or before the Closing of each of the following conditions:

     5.1   Representations and Warranties.  The representations and warranties
of the Company contained in Sections 2 and 3 shall be true, in all material
respects, on and as of the Closing with the same effect as though such

Closing.

     5.3   Compliance Certificate.  An executive officer of the Company shall

prospects, operations, properties, assets or condition of the Company since
August 31, 1992 other than as disclosed herein.

                                      -11-

     5.4   Proceedings and Documents.  All corporate and other proceedings in
connection with the transactions contemplated at the Closing and all documents
incident thereto shall be reasonably satisfactory in form and substance to New
Investors purchasing at least a majority of the Series B Preferred Stock and
they shall have received all such counterpart original and certified or other
copies of such documents as they may reasonably request.

     5.5   Opinion of Counsel.  Each New Investor shall have received from
Worsham, Forsythe, Sampels & Wooldridge an opinion, dated as of the Closing, in
form and substance satisfactory to the Investors, to the effect that:

     (a)   The Company is a corporation duly organized, validly existing and in
           good standing under the laws of the State of Delaware, and the
           Company has the requisite corporate power and authority to own its
           properties and to conduct its business. The Company has no
           subsidiaries other than Specialized Network Services, Inc. of which
           the Company owns all of the issued and outstanding capital stock.

     (b)   The Company is qualified to do business as a foreign corporation in
           the States of Texas, California, Louisiana, Oklahoma, Georgia and
           Tennessee.

     (c)   The Company has the requisite corporate power and authority to
           execute, deliver and perform this Agreement. The Agreement has been
           duly and validly authorized by the Company, duly executed and
           delivered by an authorized officer of the Company and constitutes a
           legal, valid and binding obligation of the Company. Subject to the
           exercise of judicial discretion, equitable principles and bankruptcy
           and other laws of general application affecting the rights and
           remedies of its creditors, the Agreement is enforceable according to
           its terms, except insofar as public policy may limit the
           enforceability of the indemnification provisions of Section 7.10 of
           the Agreement and except that no opinion need be given as to the
           availability of equitable remedies.

     (d)   The capitalization of the Company is as follows:

           (i)   Preferred Stock. 7,500,000 shares of preferred stock, $.10 par
                 value per share, of which 4,150,000 shares have been designated
                 as Series A Preferred Stock and 3,250,000 shares have been
                 designated as Series B Preferred Stock. 3,944,184 shares of the
                 Series A Preferred Stock have been duly authorized, issued and
                 delivered, are validly outstanding, fully paid and
                 nonassessable, and were offered and sold in compliance with
                 exemptions from the registration provisions of all applicable
                 federal and Texas securities laws. The shares of Series B
                 Preferred Stock being purchased pursuant to this Agreement have
                 been duly authorized, issued and delivered, are validly
                 outstanding, fully paid and nonassessable, and have been
                 approved by all requisite stockholder action. The respective

                                      -12-

<PAGE>
 
                 rights, privileges and preferences of the Series B Preferred
                 Stock are as stated in the Series B Designation attached as
                 Exhibit "A" to this Agreement. The Common Stock issuable upon
                 the exercise of the Warrants and the conversion of the Series B
                 Preferred Stock purchased under this Agreement has been duly
                 and validly reserved for issuance and, when issued in
                 accordance with the Warrants or the Series B Designation, as
                 the case may be, will be validly issued, fully paid and
                 nonassessable.

          (ii)   Common Stock.  13,000,000 shares of Common Stock, $.01 par
                 value per share, of which 201,611 have been duly authorized,
                 issued and delivered and are validly outstanding, fully paid
                 and nonassessable and were offered and sold in compliance with
                 exemptions from the registration provisions of all applicable
                 federal and Texas securities laws.

          (iii)  Except for the items on Schedule 2.2 of this Agreement, there
                 are no preemptive rights or, to the best of such counsel's
                 knowledge, options, warrants, conversion privileges or other
                 rights (or agreements for any such rights) outstanding to
                 purchase or otherwise obtain any of the Company's securities.

     (e)   The certificates representing shares of the Series B Preferred Stock
           and shares of Common Stock are in due and proper form. The form of
           Warrant complies with the requirements of the General Corporation Law
           of the State of Delaware applicable thereto. The documents attached
           to the Agreement as Exhibit "A" are true, complete and accurate
           copies of the Restated Certificate of Incorporation of the Company,
           as amended (including the Series B Designation) and the Bylaws of the
           Company, as amended.

     (f)   The execution, delivery, performance and compliance by the Company
           with the terms of this Agreement do not violate any provision of any
           applicable federal, state or local law, rule or regulation or of any
           judgment, writ, decree or order binding upon the Company or any
           provision of the Company's Restated Certificate of Incorporation, as
           amended, or Bylaws, as amended, and, to the best of such counsel's
           knowledge, do not conflict with or constitute a default under the
           provisions of any agreement to which the Company is a party or by
           which it is bound.

     (g)   All consents, approvals, orders or authorizations of, and all
           qualifications, registrations, designations, declarations or filings
           with, any federal or state governmental authority on the part of the
           Company required in connection with the consummation of the
           transactions contemplated by this Agreement have been obtained, or
           will be timely filed, and, to the extent necessary, are effective, as
           of

                                      -13-
<PAGE>
 
           the Closing and such counsel is not aware of any proceedings, or
           threat thereof, which question the validity thereof.

     (h)   Based in part upon the representations of the New Investors, the
           offer and sale of the Series B Preferred Stock and Warrants pursuant
           to the terms of this Agreement are exempt from the registration
           requirements of Section 5 of the Securities Act of 1933, as amended,
           by virtue of Sections 3(b) or 4(2) thereof and from the registration
           or qualification requirements of any securities laws or regulations
           of the State of Texas.

     (i)   Such counsel is not aware that there is any action, proceeding or
           investigation pending against the Company or any of its officers,
           directors or employees, or that any of the foregoing has received any
           threat thereof, which questions the validity of this Agreement, or
           the right of the Company to enter into this Agreement or, which might
           result, either individually or in the aggregate, in any materially
           adverse change in the assets, condition, affairs or prospects of the
           Company.

     (j)   Such counsel is not aware that the Company is in violation of any
           provision of its Certificate of Incorporation, as amended, or Bylaws,
           as amended, nor that either of such documents is in violation of the
           General Corporation Law of the State of Delaware, which violation
           might result, either individually or in the aggregate, in any
           material adverse change in the assets, condition, affairs or
           prospects of the Company.

     6.    Conditions of the Company's Obligations at Closing.  The obligations
of the Company to each New Investor under this Agreement are subject to the
fulfillment on or before the Closing of the following conditions:

     6.1   Representations and Warranties.  The representations and warranties
of the New Investor contained in Section 4 shall be true on and as of the
Closing with the same effect as though such representations and warranties had
been made on and as of the Closing.

     6.2   Proceedings and Documents.  All corporate and other proceedings in

           A Preferred Stock which may be purchased pursuant to the exercise of
           those certain warrants issued by the Company to certain equipment
           lessors as described on Schedule 2.13 hereof, and the Series B
           Preferred Stock issued to the New Investors pursuant to this
           Agreement); (2) Common Stock issued upon the exercise of the
           Warrants; (3) Common Stock issued as (or issuable upon the conversion
           or exercise of any warrant, right or other security which is issued
           as) a dividend or other distribution with respect to, or in exchange
           for or in replacement of, Preferred Stock or Common Stock; (4) Common
           Stock otherwise issued (or issuable upon the conversion or exercise
           of any warrant, right or other security) to an Investor; and (5) for
           the purposes of the rights and obligations provided under Section 7.3
           only and only while he is in the employ of the Company, shares of the
           Company's capital stock owned of record by John W. Merritt (the
           "Founder"); excluding in all cases, however, any Registerable
           Securities sold by a person in a transaction in which his rights
           under this Section 7 are not assigned.

     (c)   The number of shares of "Registerable Securities then outstanding"
           shall be determined by the number of shares of Common Stock
           outstanding which are, and the number of shares of Common Stock
           issuable pursuant to Preferred Stock and Warrants and then
           exercisable or convertible into securities which are, Registerable
           Securities.

     (d)   The term "Holder" means any person owning or having the right to
           acquire Registerable Securities or any assignee thereof in accordance
           with Section 7.13 hereof.

     (e)   The term "Form S-3" means such form under the Act as in effect on the
           date hereof or any registration form under the Act subsequently
           adopted by the Securities and Exchange Commission ("SEC") which
           permits inclusion or

                                      -15-
<PAGE>
 
           incorporation of substantial information by reference to other
           documents filed by the registrant with the SEC.

     7.2   Request for Registration.

     (a)   At any time after October 31, 1993, any Holder, or Holders, holding
           an aggregate of not less than thirty percent (30%) of the
           Registerable Securities then outstanding (the "Initiating Holder(s)")
           may request by written notice, specifying the number of shares
           desired to be sold, that the Company file a registration statement
           covering a public offer and sale of Registerable Securities. Upon
           such request, the Company shall promptly give written notice of the
           proposed registration to all other Holders. All such other Holders
           who notify the Company in writing within fifteen (15) days of the
           date of the notice given them by the Company, of their desire to join
           in the request and the number of shares they desire to sell shall be
           deemed to be Initiating Holders. Thereupon, the Company shall use its
           best efforts to effect, as soon as reasonably practicable, the
           registration under the Act of all Registerable Securities which the
           Holders request to be registered (subject to the limitations of
           Section 7.4 hereof).

     (b)   The Company is obligated to effect only two (2) such registrations
           pursuant to this Section 7.2.

     (c)   Notwithstanding the foregoing, if the Company shall furnish to
           Holders requesting a registration statement pursuant to this Section
           7.2, a certificate signed by the chief executive officer of the
           Company stating that in the good faith judgment of the Board of
           Directors of the Company, it would be detrimental to the Company and
           its stockholders for such registration statement to be filed and it
           is, therefore, necessary or appropriate to defer the filing of such
           registration statement, the Company shall have the right to defer
           such filing for a period of not more than ninety (90) days after
           receipt of the request of the Initiating Holders; provided, however,
           that the Company may not utilize this right more than once in any 12-
           month period.

     7.3   Company Registration.  At any time that the Company intends to make a
public offering of its securities under any form of registration statement
selected by it and available for secondary offerings (other than a registration
relating solely to (i) the Company's initial public offering, (ii) the sale of
securities to employees of the Company pursuant to a stock option, stock
purchase or similar plan or (iii) an SEC Rule 145 transaction), the Company
shall notify in writing all Holders no less than fifteen (15) days before the
intended filing of such registration statement and shall permit any such Holder
who so notifies the Company in writing of his desire to include any or all of
his Registerable Securities (limited only by the provisions of Section 7.4
hereof) in such offering within fifteen (15) days of receipt of the notice given
such Holders by the Company to be included in such offering.  The Company may
not commence a public offering of its securities during any registration being
made or proposed to be made pursuant to any request 

                                      -16-
<PAGE>
 
therefor in accordance with Section 7.2 hereof (other than a registration
relating either to the sale of securities to employees of the Company pursuant
to a stock option, stock purchase or similar plan or an SEC Rule 145
transaction).

     7.4   Underwriting Requirements.  If any registration is intended to be an
underwritten public offering, the Company shall so advise the Holders as a part
of the written notice given pursuant to Sections 7.2 and 7.3 hereof.  In such
event the right of any Holder to registration pursuant to Sections 7.2 and 7.3
shall be conditioned upon such Holder's participation in such underwriting and
the inclusion of such Holder's securities in the underwriting to the extent
provided herein.  Any and all Holders proposing to distribute their securities
through such underwriting shall (together with the Company and any other persons
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the underwriter, or underwriters,
or representatives thereof, selected for such underwriting by the Company
(hereinafter the "Underwriter"), provided that such underwriting agreement shall
not provide for indemnification or contribution obligations on the part of
Holders greater than the obligations of the Holders pursuant to Section 7.10(b)
hereof.  Notwithstanding any other provision of Sections 7.2 and 7.3 to the
contrary, if the Underwriter, acting in good faith, determines that marketing
factors require a limitation of the number of shares to be underwritten, the
Underwriter may exclude some of the Holders' shares of stock from such
registration and underwriting, provided that shares of stock proposed to be sold
by stockholders other than the Holders (but not including (i) stockholders who
have been employed by the Company for more than three (3) years and (ii) other
holders to whom rights have been granted in accordance with Section 7.14 hereof)
are first excluded and provided further that in any registration pursuant to
Section 7.3 no less than twenty percent (20%) of the aggregate number of shares
offered thereby are offered by the Holders (or such lesser fraction as will
include all of the Registerable Securities which the Holders then desire to so
offer).  The number of shares of stock that may be included in accordance with
the foregoing sentence, shall be in proportion, as nearly as practicable, to the
respective amounts of capital stock of the Company held by all such Holders, and
all such Holders and stockholders, participating in the registration at the time
of filing of the registration statement. If any such Holder disapproves of the
terms of any such underwriting, he may elect to withdraw therefrom by written
notice to the Company and the Underwriter.  Any securities excluded or withdrawn
from such underwriting shall be withdrawn from such registration.

     7.5   Obligation of the Company.  Whenever required under this Section 7 to
effect the registration of any Registerable Securities, the Company shall, as
expeditiously as reasonably possible:

     (a)   Prepare and file with the SEC a registration statement with respect
           to such Registerable Securities and use its best efforts to cause
           such registration statement to become effective, and, upon the
           request of the Holders of a majority of the Registerable Securities
           registered thereunder, keep such registration statement effective for
           up to ninety (90) days.

                                      -17-
<PAGE>
 
     (b)   Prepare and file with the SEC such amendments and supplements to such
           registration statement and the prospectus used in connection with
           such registration statement as may be necessary to comply with the
           provisions of the Act with respect to the disposition of all
           securities covered by such registration statement.

     (c)   Furnish to the Holders such numbers of copies of the prospectus,
           including a preliminary prospectus, in conformity with the
           requirements of the Act, and such other documents as they may
           reasonably request in order to facilitate the disposition of
           Registerable Securities owned by them.

     (d)   Use its best efforts to obtain NASD clearance and register and
           qualify the securities covered by such registration statement under
           such other securities or Blue Sky laws of such jurisdictions as shall
           be reasonably requested by the Holders, provided that the Company
           shall not be required in connection therewith or as a condition
           thereto to qualify to do business, to file a general consent to
           service of process or to meet any other requirements deemed by the
           Company to be unduly burdensome in any such states or jurisdictions.

     (e)   Notify each Holder of Registerable Securities covered by such
           registration statement, or the Holder's designated attorney-in-fact,
           at any time when a prospectus relating thereto covered by such
           registration statement is required to be delivered under the Act, of
           the happening of any event as a result of which the prospectus
           included in such registration statement, as then in effect, includes
           an untrue statement of a material fact or omits to state a material
           fact required to be stated therein or necessary to make the
           statements therein not misleading in the light of the circumstances
           then existing.

     (f)   Furnish, at the request of any Holder requesting registration of
           Registerable Securities pursuant to this Section 7, on the date that
           such Registerable Securities are delivered to the underwriters for
           sale in connection with a registration pursuant to this Section 7, if
           such securities are being sold through underwriters, or, if such
           securities are not being sold through underwriters, on the date that
           the registration statement with respect to such securities becomes
           effective (i) an opinion, dated such date, of the counsel
           representing the Company for the purposes of such registration, in
           form and substance as is customarily given to underwriters in an
           underwritten public offering, addressed to the underwriters, if any,
           and to the Holders requesting registration of Registerable Securities
           and (ii) a letter dated such date, from the independent certified
           public accountants of the Company, in form and substance as is
           customarily given by independent certified public accountants to
           underwriters in an underwritten public offering, addressed to the
           underwriters, if any, and to the Holders requesting registration of
           Registerable Securities.

                                      -18-
<PAGE>
 
     7.6   Furnish Information.  It shall be a condition precedent to the
obligations of the Company to effect any registration pursuant to this Section 7
as to each selling Holder that such selling Holder shall furnish to the Company
such information regarding itself, the Registerable Securities held by it, and
the intended method of disposition of such securities as shall be required to
effect the registration of its Registerable Securities.

     7.7   Expenses of Demand Registration.  All expenses other than
underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Section 7.2, including
(without limitation) all registration, filing and qualification fees, printers'
and accounting fees, and fees and disbursements of counsel for the Company and
one counsel for the selling shareholders shall be borne by the Company;
provided, however, that the Company shall not be required to pay for any
expenses of any registration proceeding begun pursuant to Section 7.2 if the
registration request is subsequently withdrawn at the request of the Holders of
a majority of the Registerable Securities to be registered (in which case all
participating Holders shall bear such expenses), unless the Holders of a
majority of the Registerable Securities agree to forfeit their right to one
demand registration pursuant to Section 7.2; provided, further, however, that if
immediately prior to the time of such withdrawal, the Holders have learned of a
materially adverse change in the condition, business or prospects of the Company
from that known to the Holders at the time of their request, then the Holders
shall not be required to pay any of such expenses and shall retain their rights
pursuant to Section 7.2.

     7.8   Expenses of Company Registration.  The Company shall bear and pay all
expenses, other than underwriting discounts and commissions relating to the
shares of any Holder(s) being offered thereby, incurred in connection with any
registration, filing or qualification of Registerable Securities with respect to
the registrations pursuant to Section 7.3 for each Holder (which right may be
assigned as provided in Section 7.13), including (without limitation) all
registration, filing, and qualification fees, printing, legal and accounting
fees relating or apportionable thereto; provided, however, that the Company
shall pay the fees and disbursements of only one counsel for the selling
shareholders selected by them.

     7.9   Delay of Registration.  No Holder shall have any right to obtain or
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 7.

     7.10  Indemnification.  In the event any Registrable Securities are
included in a registration statement under this Section 7:

     (a)   To the extent permitted by law, the Company will indemnify and hold
           harmless each Holder, the officers, directors, partners and agents of
           each Holder, any underwriter (as defined in the Act) for such Holder
           and each person, if any, who controls such Holder or underwriter
           within the meaning of the Act or the Securities Exchange Act of 1934,
           as amended (the "1934 Act"), against any losses, claims, damages, or
           liabilities (joint or several) to which they may become subject under
           the Act, the 1934 Act or other federal or state laws, insofar as such

                                      -19-
<PAGE>
 
           losses, claims, damages or liabilities (or actions in respect
           thereof) arise out of or are based upon any of the following
           statements, omissions or violations (collectively a "Violation"): (i)
           any untrue statement or alleged untrue statement of a material fact
           contained in such registration statement, including any preliminary
           prospectus or final prospectus contained therein or any amendments or
           supplements thereto, (ii) the omission or alleged omission to state
           therein a material fact required to be stated therein, or necessary
           to make the statements therein not misleading, or (iii) any violation
           or alleged violation by the Company of the Act, the 1934 Act or any
           state securities law; and the Company will reimburse each such
           Holder, officer, director, partner, agent, underwriter or controlling
           person for any legal or other expenses reasonably incurred by them in
           connection with investigating or defending any such loss, claim,
           damage, liability, or action; provided, however, that the indemnity
           agreement contained in this subsection 7.10(a) shall not apply to
           amounts paid in settlement of any such loss, claim, damage, liability
           or action if such settlement is effected without the consent of the
           Company (which consent shall not be unreasonably withheld), nor shall
           the Company be liable in any such case for any such loss, claim,
           damage, liability, or action to the extent that it arises out of or
           is based upon a Violation which occurs in reliance upon and in
           conformity with written information furnished expressly for use in
           connection with such registration by any such Holder, underwriter or
           controlling person.

     (b)   To the extent permitted by law, each selling Holder will indemnify
           and hold harmless the Company, each of its directors, each of its
           officers who have signed the registration statement, each person, if
           any, who controls the Company within the meaning of the Act, any
           underwriter and any other Holder selling securities in such
           registration statement or any of its directors, officers, partners or
           agents, or any person who controls such Holder, against any losses,
           claims, damages or liabilities (joint or several) to which the
           Company or any such director, officer, controlling person, or
           underwriter may become subject, under the Act, the 1934 Act or other
           federal or state law, insofar as such losses, claims, damages, or
           liabilities (or actions in respect thereof) arise out of or are based
           upon any Violation, in each case to the extent (and only to the
           extent) that such Violation occurs in reliance upon and in conformity
           with written information furnished by such Holder expressly for use
           in connection with such registration and in each case in an amount
           which shall not exceed the gross proceeds of the offering received by
           such Holder; and each such Holder will reimburse any legal or other
           expenses reasonably incurred by the Company or any such director,
           officer, controlling person or underwriter, any other Holder, or any
           of its officers, directors, partners or agents, or any controlling
           person in connection with investigating or defending any such loss,
           claim, damage, liability or action; provided, however, that the
           indemnity agreement contained in this subsection 7.10(b) shall not
           apply to amounts paid in settlement of any such loss, claim,

                                      -20-
<PAGE>
 
           damage, liability or action if such settlement is effected without
           the consent of the Holder, which consent shall not be unreasonably
           withheld.

     (c)   Promptly after receipt by an indemnified party under this Section
           7.10 of notice of the commencement of any action (including any
           governmental action), such indemnified party will, if a claim in
           respect thereof is to be made against any indemnifying party under
           this Section 7.10, deliver to the indemnifying party a written notice
           of the commencement thereof and the indemnifying party shall have the
           right to participate in, and, to the extent the indemnifying party so
           desires, jointly with any other indemnifying party, similarly
           noticed, to assume the defense thereof with counsel mutually
           satisfactory to the parties; provided, however, that an indemnified
           party shall have the right to retain its own counsel, with the fees
           and expenses to be paid by the indemnifying party, if representation
           of such indemnified party by the counsel retained by the indemnifying
           party would be inappropriate due to actual or potential differing
           interests between such indemnified party and any other party
           represented by such counsel in such proceeding. The failure to
           deliver written notice to the indemnifying party within a reasonable
           time of the commencement of any such action, if prejudicial to its
           ability to defend such action, shall relieve such indemnifying party
           of any liability to the indemnified party under this Section 7.10,
           but the omission so to deliver written notice to the indemnifying
           party will not relieve it of any liability that it may have to any
           indemnified party otherwise than under this Section 7.10.

     7.11  Reports Under Securities Exchange Act of 1934.  With a view to making
available to the Holders the benefits of Rule 144 promulgated under the Act and
any other rule or regulation of the SEC that may at any time permit a Holder to
sell securities of the Company to the public without registration or pursuant to
a registration on Form S-3, the Company agrees to:

     (a)   make and keep public information available, as those terms are
           understood and defined in SEC Rule 144, at all times after ninety
           (90) days after the effective date of the first registration
           statement filed by the Company for the offering of its securities to
           the general public;

     (b)   take such action, including the voluntary registration of its Common
           Stock under Section 12 of the 1934 Act, as is necessary to enable the
           Holders to utilize Form S-3 for the sale of their Registerable
           Securities, such action to be taken as soon as practicable after the
           end of the fiscal year in which the first registration statement
           filed by the Company for the offering of its securities to the
           general public is declared effective;

     (c)   file with the SEC in a timely manner all reports and other documents
           required of the Company under the Act and the 1934 Act; and

                                      -21-
<PAGE>
 
     (d)   furnish to any Holder, so long as the Holder owns any Registerable
           Securities, forthwith upon request (i) a written statement by the
           Company that it has complied with the reporting requirements of SEC
           Rule 144 (at any time after ninety (90) days after the effective date
           of the first registration statement filed by the Company), the Act
           and the 1934 Act (at any time after it has become subject to such
           reporting requirements), or that it qualifies as a registrant whose
           securities may be resold pursuant to Form S-3 (at any time after it
           so qualifies), (ii) a copy of the most recent annual or quarterly
           report of the Company and such other reports and documents so filed
           by the Company, and (iii) such other information as may be reasonably
           requested in availing any Holder of any rule or regulation of the SEC
           which permits the selling of any such securities without registration
           or pursuant to such form.

     7.12  Form S-3 Registration.  In case the Company shall receive from any
Holder or Holders a written request or requests that the Company effect a
registration on Form S-3 and any related qualification or compliance with
respect to all or a part of the Registerable Securities owned by such Holder or
Holders, the Company will:

     (a)   promptly give written notice of the proposed registration, and any
           related qualification or compliance, to all other Holders; and

     (b)   as soon as practicable, effect such registration and all such
           qualifications and compliances as may be so requested and as would
           permit or facilitate the sale and distribution of all or such portion
           of such Holder's or Holders' Registerable Securities as are specified
           in such request, together with all or such portion of the
           Registerable Securities of any other Holder or Holders joining in
           such request as are specified in a written request given within
           fifteen (15) days after receipt of such written notice from the
           Company; provided, however, that the Company shall not be obligated
           to effect any such registration, qualification or compliance,
           pursuant to this Section 7.12: (1) if Form S-3 is not available for
           such offering by the Holders; (2) if the Holders, together with the
           holders of any other securities of the Company entitled to inclusion
           in such registration, propose to sell Registerable Securities and
           such other securities (if any) at an aggregate price to the public
           (net of any underwriters' discounts or commissions) of less than
           $1,000,000; (3) if the Company shall furnish to the Holders a
           certificate signed by the chief executive officer of the Company
           stating that in the good faith judgment of the Board of Directors of
           the Company, it would be seriously detrimental to the Company and its
           stockholders for such Form S-3 registration to be effected at such
           time, in which event the Company shall have the right to defer the
           filing of the Form S-3 registration statement for a period of not
           more than ninety (90) days after receipt of the request of the Holder
           or Holders under this Section 7.12, provided, however, that the
           Company shall not utilize this right more than once in any 12-month
           period; (4) if the Company has, within the 12-month period preceding
           the date of such request, already effected one registration

                                      -22-
<PAGE>
 
           on Form S-3 for the Holders pursuant to this Section 7.12; or (5) in
           any particular jurisdiction in which the Company would be required to
           qualify to do business or to execute a general consent to service of
           process in effecting such registration, qualification or compliance.

     (c)   Subject to the foregoing, the Company shall file a registration
           statement covering the Registerable Securities and other securities
           so requested to be registered as soon as practicable after receipt of
           the request or requests of the Holders. All expenses incurred in
           connection with a registration requested pursuant to the provisions
           of Section 7.12, including (without limitation) all registration,
           filing qualification, printer's and accounting fees and the
           reasonable fees and disbursements of counsel for the selling Holder
           or Holders and counsel for the Company shall be borne pro rata by the
           Holder or Holders participating in the Form S-3 Registration.
           Registrations effected pursuant to this Section 7.12 shall not be
           counted as demands for registration or registrations effected
           pursuant to Sections 7.2 or 7.3, respectively.

     7.13  Assignment of Registration Rights.  The rights to cause the Company
to register Registerable Securities pursuant to this Section 7 may be assigned
by a Holder to a transferee or assignee of such securities provided the Company
is, within thirty (30) days after such transfer, furnished with written notice
of the name and address of such transferee or assignee and the securities with
respect to which such registration rights are being assigned; and provided
further, that (i) such assignee or transferee agrees to be bound by the terms of
this Agreement; and (ii) such assignment or transfer is made other than in
connection with the public offering of such stock or in a transaction (pursuant
to Rule 144 or any successor rule) as a consequence of which the subsequent
transfer of such stock is not restricted under the Act.

     7.14  Limitations on Subsequent Registration Rights.  From and after the
date of this Agreement, the Company shall not, without the prior written consent
of the Holders of a majority of the outstanding Registerable Securities, enter
into any agreement with any holder or prospective holder of any securities of
the Company which would allow such holder or prospective holder (a) to include
such securities in any registration filed under Section 7.3 hereof, unless under
the terms of such agreement, such holder or prospective holder may include such
securities in any such registration only to the extent that the inclusion of his
securities will be on the same basis as the inclusion of the Registerable
Securities of the Holders or (b) to have any securities included in any
registration effected pursuant to Section 7.2.

     7.15  "Market Stand-Off" Agreement.  Each Holder hereby agrees that it
shall not, to the extent requested by the Company or the Underwriter, sell or
otherwise transfer or dispose of any Registerable Securities (other than those
included in the registration or those transferred to persons who agree to be
similarly bound) during the period not to exceed one hundred eighty (180) days
following the effective date of a registration statement of the Company filed
under the Act; provided, however, that such agreement shall be applicable only
to the first such registration 

                                      -23-
<PAGE>
 
statement of the Company which covers shares (or securities) to be sold on its
behalf to the public in an underwritten offering.

     In order to enforce the foregoing covenant, the Company may impose stop
transfer instructions with respect to the Registerable Securities of each
Investor (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.

     7.16  Termination of Registration Rights.  A Holder's rights pursuant to
this Section 7 shall terminate at the earlier of (a) such time as the Holder
may, within a three-month period, offer and sell all of his Registerable
Securities pursuant to Rule 144 under the Act without any adverse effect on the
price at which such Registerable Securities may be sold, such determination as
to such adverse effect to be made by such Holder acting in good faith, or (b)
the date forty-eight (48) months from the closing of its Qualified IPO.

     8.    Board of Directors.

     8.1   Size of Board of Directors.  At the time of the Closing, the Board of

times a Board of Directors whose membership conforms with the provisions of this
Section 8.2. The Board of Directors, in filling any vacancy or newly created
directorship, shall likewise elect and maintain a Board of Directors whose
membership conforms with the provisions of this Section 8.2.

     8.3   Termination of Voting Agreement.  At the earlier of: (i) such time as

     9.    Covenants of the Company.

     9.1   Delivery of Financial Statements.

     (a)   The Company shall deliver to each Investor then holding shares of
           Preferred Stock (or Common Stock into which Preferred Stock has been
           converted):

           (i)   as soon as practicable, but in any event within ninety (90)
                 days after the end of each fiscal year of the Company, an
                 income statement for such fiscal year, a balance sheet of the
                 Company as of the end of such year, and a schedule as to the
                 sources and applications of funds for such year, such year-end
                 financial reports to be in reasonable detail, prepared in
                 accordance with generally accepted accounting principles
                 ("gaap"), and audited and certified by independent public
                 accountants of nationally recognized standing selected by the
                 Company;

           (ii)  as soon as practicable, but in any event within forty-five (45)
                 days after the end of the first three (3) quarters of each
                 fiscal year of the Company, an unaudited balance sheet as of
                 the end of such fiscal quarter, in reasonable detail and
                 prepared in accordance with gaap; and

           (iii) such other information relating to the financial condition,
                 business, prospects or corporate affairs of the Company as the
                 Investor or any assignee of the Investor may from time to time
                 request in writing.

     (b)   The Company shall deliver to each Investor then holding 38,250 or
           more shares of the outstanding Preferred Stock, or Common Stock into
           which such Preferred Stock has been converted (as adjusted to reflect
           subsequent changes in the capitalization of the Company and
           aggregating the holdings of affiliated Investors solely for the
           purpose hereof) (a "Qualified Investor"):

           (i)   within forty-five (45) days of the end of each month, an
                 unaudited income statement and balance sheet for and as of the

                 including balance sheets

                                      -25-

              and sources and applications of funds statements for such months
              and, as soon as prepared, any other budgets or revised budgets
              prepared by the Company to the extent prepared for presentation to
              the Board of Directors of the Company;

     (c)   With respect to the financial statements called for in subsections
           (a)(ii) and (b)(i) of this Section 9.1, the Company shall deliver to
           each Investor an instrument executed by the Chief Financial Officer
           of the Company and certifying that such financials were prepared in
           accordance with gaap consistently applied with prior practice for
           earlier periods and fairly present the financial condition of the
           Company and its result of operation for the period specified, subject
           to normal year-end audit adjustment;

     (d)   Any information provided pursuant to Sections 9.1(a)(iii) and
           9.1(b)(ii) shall be used by the Investor or any assignee of the
           Investor solely in furtherance of its interests as an Investor in the
           Company, and the Investor and any assignee of the Investor shall use
           all reasonable effort to maintain the confidentiality of all non-
           public information of the Company obtained under said sections,
           provided the Company makes an appropriate designation of any such
           confidential information, and provided further that the foregoing
           shall not prohibit any Investor from communicating information
           reasonably necessary or appropriate in fulfilling any fiduciary duty
           to its stockholders or partners, any committees thereof, or the like.
           The Company shall not be obligated to disclose any confidential and
           proprietary non-financial information, the disclosure of which it
           believes in good faith would be detrimental to the Company and its
           stockholders.

     9.2   Inspection.  The Company shall permit each Qualified Investor, at
such Qualified Investor's expense, to visit and inspect the Company's
properties, to examine its books of account and records and to discuss the
Company's affairs, finances and accounts with its officers, all at such
reasonable times as may be requested by the Qualified Investor; provided,
however, that the Company shall not be obligated pursuant to this Section 9.2 to
provide access to any information which it reasonably considers to be a trade
secret or similar confidential information.  In addition to such inspection
right, the Company shall invite each Qualified Investor to attend all meetings
of its Board of Directors in a nonvoting observer capacity.  The Company shall
provide all such New Investors with copies of all notices and other materials
provided to the Company's directors.

     9.3   Assignment of Information and Visitation Rights.  The rights granted
to Investors under Sections 9.1 and 9.2 may be assigned in connection with the
transfer or assignment of any shares of Preferred Stock or Common Stock into
which Preferred Stock has been converted, provided that the Company shall be
entitled to notice of any such transfer within thirty (30) days of the date such
transaction is effected, and provided further that such assignee or transferee
agrees to be bound by the terms of this Agreement.

     9.4   Termination of Covenants.  The covenants set forth in subsections
9.1(a)(iii), (b) and (c) and Section 9.2 shall terminate as to Investors and be
of no further force or effect at such time as the Company may become subject to
the periodic reporting requirements of Section 15(d) of the 1934 Act, or
register its Common Stock under Section 12 of the 1934 Act, whichever event
shall first occur.

     9.5   Right of First Refusal.  Subject to the terms and conditions
specified in this Section 9.5, the Company hereby grants to the Qualified
Investors and the Founder who are then in the employ of the Company (for the
purposes hereof, the Qualified Investors and such Founder shall be referred to
collectively as the "Qualified Shareholders") a right of first refusal with
respect to future sales by the Company of its Shares (as hereinafter defined).

     Each time the Company proposes to offer any shares of, or securities
convertible into or exercisable for, any class of its capital stock ("Shares"),
the Company shall first make an offering of such Shares to each Qualified
Shareholder in accordance with the following provisions:

     (a)   The Company shall deliver a notice by certified mail ("Notice") to
           the Qualified Shareholders stating (i) its bona fide intention to
           offer or issue such Shares, (ii) the approximate number of such
           Shares to be offered, (iii) the approximate price, if any, for which
           it proposes to offer such Shares, and (iv) in case of a non-public
           offering, and if and to the extent then known, the name(s) of the
           proposed offeree(s).

     (b)   Within twenty (20) calendar days after receipt of the Notice, each
           Qualified Shareholder may elect (by written notice delivered to the
           Company within such period) to purchase or obtain, at the price and
           on the terms specified in the Notice, up to that portion of such
           Shares which equals the proportion that the number of shares of
           Common Stock issue and held, or issuable upon the conversion of the
           Preferred Stock or exercise of the Warrants then held by such
           Qualified Shareholder, bears to the total number of shares of Common
           Stock issued and held, or issuable upon conversion of Preferred Stock
           or exercise of the Warrants then held, by all the Qualified
           Shareholders. The Company shall promptly, in writing, inform each
           Qualified Shareholder which purchases all the Shares available to it
           ("Fully-Exercising Investor") of any other Qualified Shareholder's
           failure to do likewise. During the ten-day period commencing after
           receipt of such information, each Fully-Exercising Investor shall be
           entitled to obtain (by written notice delivered to the Company within
           such period) that portion of the Shares not subscribed for by the
           Qualified Shareholders which is equal to the proportion that the
           number of shares of Common Stock issued and held, or issuable upon
           conversion of Preferred Stock or exercise of the Warrants then held,
           by such Fully-Exercising Investor bears to the total number of shares
           of Common Stock issued and held, or issuable upon conversion of
           Preferred Stock or exercise of the Warrants then held, by all Fully
           Exercising Investors who wish to purchase some of the unsubscribed
           Shares.

                                      -27-
<PAGE>
 
     (c)   If any of such Shares referred to in the Notice are not elected to be
           obtained as provided in subsection 9.5(b) hereof, the Company may,
           during the 45-day period following the expiration of the period
           provided in subsection 9.5(b) hereof, offer such remaining
           unsubscribed Shares at a price not less than, and upon terms no more
           favorable to the offeree than those specified in the Notice. If the
           Company does not enter into an agreement for the sale of the Shares
           within such period, or if such agreement is not consummated within 45
           days of the execution thereof, the right provided hereunder shall be
           deemed to be revived and such Shares shall not be offered unless
           first reoffered to the Investors in accordance herewith.

     (d)   The following shall not constitute an offer and sale by the Company
           for purposes of this Section 9.5: (i) the conversion of shares of
           Preferred Stock and issuance of Common Stock pursuant thereto; (ii)
           the issuance of Common Stock pursuant to the exercise of the
           Warrants; (iii) the exercise of options and warrants which are
           outstanding or listed on Schedule 2.2 hereof (including any
           additional shares issuable pursuant to the operation of the
           antidilution features of such options and warrants or by amendment
           thereto in satisfaction of such antidilution features), the issuance
           of Preferred Stock or Common Stock pursuant thereto, and the
           conversion of the Preferred Stock issued pursuant to any such
           exercise and the issuance of Common Stock pursuant thereto; (iv) the
           issuance and sale of Common Stock or options or other rights (and
           Common Stock issued upon exercise thereof) for up to 3,201,976 shares
           of Common Stock pursuant to a stock option plan or other stock-based
           compensation plan approved by the stockholders and directors of the
           Company (less any shares issuable or issued pursuant to the exercise
           of any option granted under such stock option plan prior to the date
           of this Agreement); (v) 50,000 additional shares of Common Stock,
           including options or warrants therefor issued or issuable from time
           to time in the discretion of the Board of Directors of the Company;
           (vi) the issuance and sale of Common Stock or Preferred Stock, or
           warrants, options or similar rights therefor, and the issuance of
           Common Stock or Preferred Stock upon the exercise of any such rights,
           provided that the aggregate consideration received or to be received
           upon the issuance of such stock shall be at least $4.00 per share
           (adjusted to reflect subsequent changes in the capitalization of the
           Company; and (vii) the issuance and sale of Series B Preferred Stock
           pursuant to Section 1.3 hereof.

     (e)   The right of first refusal granted under this Section 9.5 (i) shall
           not be assignable except in connection with the transfer by a
           Qualified Shareholder of Preferred Stock (or Common Stock into which
           such Preferred Stock has been converted) as a result of which such
           transferee shall hold at least 38,250 shares of the outstanding
           Preferred Stock, or Common Stock into which such Preferred Stock has
           been converted (as adjusted to reflect subsequent changes in the
           capitalization

                                      -28-
<PAGE>
 
           of the Company and aggregating the holdings of any affiliated
           Investors and transferees solely for the purpose of determining
           whether or not such transferee holds such minimum number of shares);
           and (ii) in all events shall expire at such time as the Company may
           complete its initial firm commitment underwritten public offering of
           its Common Stock pursuant to a registration statement under the Act
           on Form S-1 or its then equivalent.

     9.6   Affirmative Covenants.  Without limiting any other covenants and
provisions hereof, the Company covenants and agrees that so long as Preferred
Stock or Common Stock issued upon conversion thereof is outstanding and held by
the Investors hereunder, the Company shall (unless it has received the written
consent of the Investors holding such number of shares of the Company's capital
stock specified in Section 10.10 of this Agreement to effect a wavier or
amendment of such covenants and provisions) perform and observe the following
covenants and provisions:

     (a)   The Company will promptly pay and discharge, or cause to be paid and
           discharged, when due and payable, all lawful taxes, assessments, and
           governmental charges or levies imposed upon the income, profits,
           property, or business of the Company or any subsidiary; provided,
           however, that any such tax, assessment, charge or levy need not be
           paid if the validity thereof shall currently be contested in good
           faith by appropriate proceedings and if the Company shall have set
           aside on its books adequate reserves with respect thereto, and
           provided further, that the Company will pay all such taxes,
           assessments, charges, or levies forthwith upon the commencement of
           proceedings to foreclose any lien that may have attached as security
           therefor. The Company will promptly pay or cause to be paid when due,
           or in conformance with customary trade terms, all other indebtedness
           incident to the operations of the Company, except indebtedness
           contested in good faith by the Company;

     (b)   The Company will keep its properties and those of its subsidiaries in
           good repair, working order, and condition, reasonable wear and tear
           excepted, and from time to time make all needful and proper repairs,
           renewals, replacements, additions, and improvements thereto; and the
           Company and its subsidiaries will at all times comply with the
           provisions of all material leases to which any of them is a party or
           under which any of them occupies property so as to prevent any loss
           or forfeiture thereof or thereunder;

     (c)   The Company will keep its assets and those of its subsidiaries that
           are of an insurable character insured by financially sound and
           reputable insurers against loss or damage by fire, extended coverage,
           and explosion insurance in amounts customary for companies in similar
           businesses similarly situated; and the Company will maintain, with
           financially sound and reputable insurers, insurance against other
           hazards, risks, and liabilities to persons and property to the extent

                                      -29-

           and in the manner customary for companies in similar businesses
           similarly situated;

     (d)   The Company will keep true records and books of account in which
           full, true, and correct entries will be made of all dealings or
           transactions in relation to its business and affairs in accordance
           with generally accepted accounting principles applied on a consistent
           basis;

     (e)   The Company and all its subsidiaries shall duly observe and conform

           to use patents, processes, licenses, trademarks, trade names, or
           copyrights owned or possessed by it or any subsidiary and deemed by
           the Company to be necessary to the conduct of its business. The
           Company shall qualify and remain qualified, as a foreign corporation,
           in each jurisdiction in which such qualification is necessary or
           desirable in view of its business and operations or the ownership of
           its properties; and

     (g)   The Company will indemnify each Investor and such Investors'
           representatives serving on the Board of Directors of the Company, to
           the maximum extent that it is permitted to do so under applicable law
           and the Certificate of Incorporation of the Company, against
           expenses, damages, and claims (including, but not limited to,
           reasonable attorneys' fees and costs of investigation), judgments,
           fines and amounts paid in settlement, which are incurred by such
           indemnified party in connection with any pending or threatened
           action, suit or proceeding, whether civil, criminal, administrative,
           or investigative, in which such party is threatened to be made a
           party by reason of having served, or having a representative serve,
           as a director of the Company or as a director, officer, or other
           official of any company, partnership, joint venture, or other entity
           in which the Company directly or indirectly owns any equity interest,
           provided, however, that no entity or person who would otherwise be
           entitled to indemnification by virtue of the foregoing shall be so
           entitled in relation to a matter as to which such party shall be
           adjudged in a final judgment of a court of competent jurisdiction,
           subject to no further appeal, to be liable for misconduct in the
           performance of a duty to the Company unless and only to the extent
           that such applicable law permits indemnification despite such
           adjudication of liability. Expenses incurred in defending any such
           action or proceeding shall be paid by the Company in advance of the
           final disposition of such action or proceeding, subject to the
           undertaking of the indemnified party to repay such amount if it is
           ultimately determined that the indemnified party is not entitled to
           be indemnified hereunder. The remedy provided herein shall be
           cumulative of any other remedy which such indemnified

                                      -30-
<PAGE>
 
           party may have against the Company by virtue of the Company's legal
           obligation to provide indemnification for such party.

     9.7   Negative Covenants.  Without limiting any other covenants and
provisions hereof, the Company covenants and agrees that so long as Preferred
Stock of the Company or Common Stock issued upon conversion thereof is
outstanding and held by the Investors hereunder, the Company shall (unless it
has received the written consent of the Investors or the New Investors (as the
case may be) holding such number of shares of the Company's capital stock
specified in Section 10.10 of this Agreement to effect a waiver or amendment of
such covenants and provisions) comply with and observe the following negative

           pay a dividend on all series of Preferred Stock; nor will it declare
           any dividend on Common Stock unless, prior to the declaration
           thereof, it shall have provided to all holders of Preferred Stock
           notice of the proposed dividend and the record date thereof in a
           manner sufficient to enable such holders, if they elect to do so, to
           exercise the right to convert any or all of their shares of Preferred
           Stock into shares of Common Stock in time to receive the proposed
           dividend;

     (f)   Make, or permit any subsidiary to make, any loan or advance to or

           immediately prior thereto hold less than 51% of the voting power of
           the surviving corporation or entity, or permit any subsidiary to do
           so;

     (i)   Do any act or thing which would result in taxation of the holders of
           shares of the Preferred Stock under Section 305 of the Internal

     9.8   Invalid Dividend or Redemption.  Each of the Investors hereby agrees
that (i) any dividend paid in violation of the provisions of subsection 9.7(e);
and (ii) the proceeds of the redemption of any share(s) of Preferred Stock in
violation of the provisions of subsection 9.7(j), shall be held in trust for the
benefit of all Investors.

     9.9   Specific Performance.  The Company and the Investors each agree that
if any covenant set forth in Sections 9.6 and 9.7 is breached, remedies at law
might be inadequate and that, all such covenants shall, therefore, be
enforceable by specific performance.  The remedy of specific performance shall
not be an exclusive remedy, but shall be cumulative of all other rights and
remedies at law, in equity or under this Agreement.

     9.10  Termination of Covenants.  The covenants contained in Sections 9.6,
9.7 and 9.8 shall terminate and be of no force and effect upon the consummation
of the Company's Qualified IPO.

     9A.   Right of Co-Sale among Qualified Investors.

     9A.1  Offer.  If any Qualified Investor receives a bona fide offer to
purchase shares of Preferred Stock or Common Stock (collectively, "Shares")
owned by it which it does not wish to accept, it shall immediately give notice
as provided in Section 10.6 of this Agreement to the other Qualified Investors,
setting forth the terms of such offer and the identity of and means of
contacting the offeror.

     9A.2  Proposed Sale.  Should any Qualified Investor desire to sell, assign,
encumber, transfer, or otherwise dispose of any of its Shares, or of any
interest in such Shares in any transaction other than an Excluded Transaction
(as hereinafter defined), it (the "Selling Investor") shall first give written
notice (the "Selling Notice") to the other Qualified Investors, in the manner
prescribed in Section 10.6 of this Agreement, of its desire to do so.  The
Selling Notice shall specify:  (i) the name and address of the person or entity
to whom the Selling Investor proposes to sell, encumber, assign, or transfer the
Shares or an interest in the Shares (the "Offeror") (ii) the number of Shares,
or the interest in the Shares the Selling Investor proposes to sell, assign, 

                                      -33-
<PAGE>
 
or transfer (the "Offered Shares"); (iii) the price or amount per Share to be
paid or delivered to the Selling Investor for the proposed sale, assignment, or
transfer; and (iv) all other terms and conditions of the proposed sale,
assignment or transfer (the "Transaction").

     9A.3  Excluded Transaction.  Each of the following shall be an Excluded
Transaction and the provisions of this Section 9A shall not apply to (i) the
transfer by a Qualified Investor that is a partnership to a partner of such
partnership or a retired partner; (ii) the transfer by a Qualified Investor that
is a corporation to its shareholders or to any subsidiary or affiliated entity;
and (iii) the transfer by a Qualified Investor that is an individual by gift,
donation or bequest to a member of his family or to a trust established for his
benefit or for the benefit of members of his family, if in each such case the
transferee(s) (but only if such transferee(s) would hold a sufficient number of
shares to be considered a Qualified Investor) agree in writing to be subject to
the terms hereof to the same extent as if it were an original Qualified Investor
hereunder.

     9A.4  Option to Purchase.  Each Qualified Investor may within thirty (30)
days of its receipt of the Selling Notice give written notice to the Selling
Investor of its election to purchase a specified number of the Shares at the
price and on the terms and conditions specified in the Selling Notice, or,
alternatively, its election to sell Shares on the terms set forth in the Selling
Notice and the number of Shares it would like to sell in the Transaction if
given the opportunity.

     9A.5  Failure to Exercise Option; Joint Sale.

           (a) Should the Qualified Investors fail to timely elect to purchase
     all of the Offered Shares specified in the Selling Notice, and if any
     Qualified Investor has timely expressed, pursuant to Section 9A.4, a desire
     to sell all or a portion of its Shares, then each such Qualified Investor
     shall be entitled to sell a portion of its Shares in the Transaction.  The
     Selling Investor shall use its best efforts to interest the Offeror in
     purchasing the Shares the Qualified Investors desire to sell, as well as
     all of the Offered Shares.  If the Offeror does not wish to purchase the
     full amount of available Shares, then the Selling Investor and each of the
     Qualified Investors shall be entitled to sell in the Transaction up to that
     number of Shares which is the same percentage of the number of Shares the
     Offeror will accept as such Qualified Investor's Share ownership bears to
     the total number of Shares owned by the Selling Investor and all of the
     Qualified Investors entitled to sell in the Transaction.

           (b) The Transaction shall then proceed on the terms and conditions
     set forth in the Selling Notice, with the Selling Investor and each
     Qualified Investor who has made the proper election selling its pro rata
     portion of Shares, as determined above.

           (c) If there are no Qualified Investors electing to participate, the
     Selling Investor shall be entitled to sell all of the Offered Shares to the
     person or entity specified in the Selling Notice at the price and on the
     terms and conditions specified in the Selling Notice, if such sale is
     consummated within sixty (60) days from the date the Selling Notice is
     first received by a Qualified Investor.  The Selling Investor may not,
     however, without 

                                      -34-
<PAGE>
 
     giving a new Selling Notice of its intention to do so, which Selling Notice
     shall reinstate the options of the Qualified Investors set forth in this
     Section 9A, sell any or all of the Offered Shares to the person or entity
     and on the terms specified in the Selling Notice after said sixty day
     period has elapsed, or to any other person or entity or at any other price
     or on any other terms and conditions than those specified in the Selling
     Notice.

           (d) The proceeds of any sale made by a Qualified Investor without
     compliance with the provisions of this Section 9A shall be deemed to be
     held in constructive trust in such amount or amounts as would have been due
     the other Qualified Investors had the Selling Investor complied with this
     Section 9A.

     9A.6  Termination of Section.  This Section 9A shall, if not earlier
terminated pursuant to Section 10.10 hereof, terminate upon the occurrence of a
Qualified IPO.

     9A.7  Transferees Subject to Provisions.  Any transferee of a Qualified
Investor who as a result of such transfer shall hold at least 38,250 shares of
outstanding Preferred Stock, or Common Stock into which such Preferred Stock has
been converted (or adjusted to reflect subsequent changes in the capitalization
of the Company and aggregating the holdings of any affiliated Investors and
transferors solely for the purpose of determining whether or not such transferee
holds such minimum number of shares) shall be subject to the terms of this
Section 9A, and must, prior to the receipt of any Shares, agree in writing to be
bound by the terms of this Section 9A.  Any transfer without such consent shall
be null and void.

     10.   Miscellaneous.

     10.1  Survival of Warranties.  The warranties, representations and
covenants of the Company contained in or made pursuant to this Agreement shall
survive the execution and delivery of this Agreement and the Closing and shall
in no way be affected by any investigation of the subject matter thereof made by
or on behalf of the Investors.

(the "Plan") is intended to advance the interests of Southwest Network Services,
Inc., a Delaware corporation (the "Company"), and its stockholders, by
encouraging and enabling selected key employees, directors and officers (who in
any such case are also employees) of, and consultants to, the Company, upon
whose judgment, initiative and effort the Company is largely dependent for the
successful conduct of its business, to acquire and retain a proprietary interest
in the Company by ownership of its stock.  It is intended that options which may
qualify for treatment as "incentive stock options" under Section 422A of the
Internal Revenue Code of 1986, as amended, and applicable regulations and
rulings promulgated thereunder (collectively, the "Code"), as well as options
which may not so qualify, may be granted under the Plan.

          (h)  "Successor" means the legal representative of the estate of a
     deceased Optionee or the person or persons who acquire the right to

     incentive stock option under all of the requirements of the Code.

          (i)  "Incentive Stock Option Agreement" means the agreement between

     between the Company and the Optionee, substantially in the form attached
     hereto as Exhibit "B" or such other form as may from time to time be
     adopted by the Board, under which the Optionee may purchase Common Stock
     pursuant to the terms of a Non-Qualified Stock Option granted under the
     Plan.

     3.   Administration of Plan.  The Plan shall be administered by the Board.
The Board shall have full and final authority in its discretion, subject to the
provisions of the Plan: (i) to determine the individuals to whom, and the time
or times at which, options shall be granted and the number of shares of Common
Stock covered by each Option; (ii) to reduce the price of outstanding options,
under such circumstances as the Board may in its discretion deem appropriate;
(iii) to construe and interpret the Plan; and (iv) to make all other
determinations and take all other actions deemed necessary or advisable for the

persons. Any committee authorized to administer the

                                     - 2 -

Plan shall consist entirely of disinterested directors in accordance with the
provisions of Rule 16b-3 under the Securities Exchange Act of 1934, as amended
(the "Exchange Act").

     4.   Common Stock Subject to Options.  The aggregate number of shares of
the Company's Common Stock which may be issued upon the exercise of Options
granted under the Plan shall not exceed 2,001,976 subject to adjustment by the
Board to reflect, as deemed appropriate by the Board, any stock dividend, stock
split, reverse stock split, share combination, reorganization, recapitalization
or the like, of or by the Company.  The shares of Common Stock to be issued upon
the exercise of options may be authorized but unissued shares, shares issued and
reacquired by the Company or shares bought on the open market for the purposes
of the Plan.  In the event any Option shall, for any reason, terminate or expire
or be cancelled or surrendered without having been exercised in full, the shares
subject to such Option, but not purchased thereunder, shall again be available
for options to be granted under the Plan.

     5.   Participants.  Options may be granted under the Plan to any person who
is an employee, director or officer (who in any such case is also an employee)
of, or a consultant (including venture capital funds and other entities
individuals associated with which have provided consulting services to the
Company) to, the Company or any of its Subsidiaries.

     6.   Terms and Conditions of Options.  Any option granted under the Plan
shall be evidenced by either an Incentive Stock Option Agreement or a Non-
Qualified Stock Option Agreement executed by the Company and the Optionee.  Such
agreement shall be subject to the following limitations and conditions:

          (a)  Option Price.  The option price per share with respect to each
     Option shall be determined by the Board but in no instance shall the option
     price for an Option which is intended to qualify as an Incentive Stock
     Option be less than 100% of the fair market value of a share of the Common
     Stock on the Date of Grant.  For the purposes hereof, the fair market value
     shall be 

                                     - 3 -
<PAGE>
 
     determined by the Board and such determination shall be final and binding
     upon the Optionee. The Board shall make such determination based on any
     reasonable valuation method.

          (b)  Payment of Option Price.  Full payment for shares purchased upon
     exercising an Option shall be made in cash or by delivery of previously
     owned shares of Common Stock, or partly in cash and partly in such stock.
     The value of shares of Common Stock delivered in connection with the
     payment of the option price shall be the fair market value of such shares
     on the Date of Exercise of the option, as determined by the Board, and such
     determination shall be binding upon the Optionee.  The Board shall make
     such determination based on any reasonable valuation method.

          (c)  Term of Option.  The expiration date of each Incentive Stock
     Option shall not be more than ten (10) years from the Date of Grant.  The
     expiration date of each Non-Qualified Stock Option shall not be more than
     ten (10) years from the Date of Grant.

          (d)  Vesting of Stockholder Rights.  Neither an Optionee nor his
     Successor shall have any of the rights of a stockholder of the Company
     until the certificate or certificates evidencing the shares purchased
     pursuant to the exercise of an Option are properly delivered to such
     Optionee or his Successor.

          (e)  Exercise of an Option.  Each Option shall be exercisable at any
     time, and from time to time, and in no particular order if the Optionee
     holds more than one Option, throughout a period commencing on the Date of
     Grant and ending upon the earliest of the expiration, cancellation,
     surrender or termination of the Option; provided however, that no Option
     shall be exercisable in whole or in part prior to the date of stockholder
     approval of the Plan.  Furthermore, the exercise of each Option shall be
     subject to the condition that if at any time the Company shall determine in
     its discretion that the satisfaction of withholding tax or other
     withholding liabilities, or that the listing, registration, or
     qualification of any share otherwise deliverable upon such 

                                     - 4 -
<PAGE>
 
     exercise upon any 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 purchase of shares pursuant thereto, 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 any conditions not
     acceptable to the Company.

          (f)  Non-ISO Tax Benefit Right.  The Board may grant a tax benefit
     right to such Optionees and on such bases as the Board shall determine,
     including, but not limited to, a tax benefit right which becomes
     exercisable only upon an optionee's being subject to the restrictions of
     Section 16 of the Exchange Act, and a provision relating thereto shall be
     included in the stock option agreement at the time the right is granted.  A
     tax benefit right may be granted only with respect to a Non-Qualified Stock
     Option under the Plan, and may be granted concurrently with or after the
     grant of the Non-Qualified Stock Option.  A tax benefit right shall entitle
     an Optionee to receive from the Company or a Subsidiary an amount in cash
     no greater than the then existing maximum statutory Federal income tax rate
     (including any surtax or similar charge or assessment) for individuals
     multiplied by the amount of ordinary income, if any, realized by the
     Optionee for Federal income tax purposes as a result of the exercise of the
     Non-Qualified Stock Option.  The Board may cancel or place a limit on the
     term of, or the amount payable for, any tax benefit right at any time.  The
     Board shall determine all other terms and provisions of any tax benefit
     right.  The Company shall not be required to fund such tax benefit right
     prior to the due date for such taxes, and the proceeds of such tax benefit
     right shall be advanced to the Optionee in the form of a check payable to
     the Internal Revenue Service for the account of the Optionee or such other
     method as the Board may determine.  The Board shall have the right to
     require an Optionee to present reasonable proof of the amount of such taxes
     as a condition precedent to the making of

                                     - 5 -
<PAGE>
 
     such payment.  The Company shall be under no obligation of any nature to
     grant any tax benefit right to any Optionee at any time.

          (g)  Nontransferability of Option.  No Option shall be transferable or
     assignable by an Optionee, voluntarily, or by operation of law, other than
     by will or the laws of descent and distribution.  Each Option shall be
     exercisable, during the Optionee's lifetime, only by him.  No Option, or
     the shares covered thereby, shall be pledged or hypothecated in any way and
     no Option, or the shares covered thereby, shall be subject to execution,
     attachment, or similar process except with the prior express written
     consent of the Board.

          (h)  Termination of Employment.  Effective July 1, 1993, upon
     termination of an Optionee's employment with the Company or with any of its
     Subsidiaries for any reason other than his death, his Option privileges
     shall be limited to the shares which were immediately purchasable by him at
     the date of such termination and such Option privileges shall expire unless
     exercised by him prior to the earlier of the date of the expiration of the
     Option or:  (i) thirty (30) days after the date of such termination in the
     event of termination for any reason other than retirement or permanent
     disability; or (ii) three (3) months after the date of such termination in
     the event of termination by reason of retirement or permanent disability.
     Neither the adoption of this Plan nor the grant of an Option to an eligible
     person shall alter in any way the Company's or the relevant Subsidiary's
     rights to terminate such person's employment at any time with or without
     cause nor does it confer upon such person any rights or privileges to
     continued employment, or any other rights and privileges, except as
     specifically provided in the Plan.

          (i)  Death of Optionee.  If an Optionee dies while an employee of the
     Company or any Subsidiary, his Option privileges shall be limited to the
     shares which were immediately purchasable by him at his date of death and
     such Option privileges shall expire unless exercised by his 

                                     - 6 -
<PAGE>
 
     successor prior to the date of its expiration or one (1) year from the date
     of the Optionee's death, whichever occurs first.

          (j)  Ten Percent Stockholders.  Notwithstanding anything herein to the
     contrary, an Option which is intended to qualify as an Incentive Stock
     Option shall be granted hereunder to any Optionee who, immediately before
     such Option is granted, beneficially owns, directly or indirectly, more
     than 10% of the total voting power of all classes of stock of the Company
     only if both of the following conditions are met:

               (i)    The Option price per share shall be no less than 110% of
     the fair market value of a share of Common Stock on the Date of Grant; and

               (ii)   The expiration date of the Option shall be not more than
     five (5) years from the Date of Grant.
     
          (k)  Other Terms.  Each Incentive Stock Option Agreement or Non-
     Qualified Stock Option Agreement, as the case may be, may contain such
     other provisions (not inconsistent herewith) as the Board in its discretion
     may determine, including, without limitation:

               (i)    in the event that an Option shall be immediately
     exercisable, any provision which shall provide that the shares acquired
     pursuant thereto shall not be deemed to have been issued pursuant to a
     fully vested stock option and thereby subject to the repurchase rights
     contained in the Shareholder's Agreement with the Optionee, entered into
     pursuant to Paragraph 10 hereof;

               (ii)   any provision which shall condition the exercise of all or
     part of an Option upon such matters as the Board may deem appropriate (if
     any) such as the passage of time, or the attainment of certain performance
     goals, appropriate to reflect the contribution of the employee to the
     performance of the Company;

                                     - 7 -
<PAGE>
 
               (iii)  any provision which would give the Board the discretionary
     authority to accelerate the exercisability of an Option in spite of any
     provision contained in an option pursuant to clause (ii) above, under such
     circumstances as the Board may deem appropriate; and

               (iv)    the manner in which an Option is to be exercised.

     7.   Allotment of Shares.  The Board shall, in its discretion, determine
the number of shares of Common Stock to be offered from time to time by grant of
Options to Optionees.  The grant of an Option shall not be deemed either to
entitle the Optionee to, or disqualify the Optionee from, participation in any
other grant of options under this Plan or any other stock option plan of the
Company.

     The above provision notwithstanding, the aggregate fair market value
(determined as of the time the Option is granted) of the Common Stock with
respect to which Options which are intended to qualify as Incentive Stock
Options are exercisable for the first time by such Optionee during any calendar
year (under all such plans of the Optionee's employer corporation and its parent
and subsidiary corporations) shall not exceed $100,000.

     8.   Adjustments.  The number of shares of Common Stock covered by each
outstanding Option granted under the Plan and the Option price shall 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 Company.  Decisions by the Board as to what
adjustments shall be made, and the extent thereof, shall be final, binding and
conclusive on all Optionees.

     9.   Designation of Incentive Stock Options.  The Board shall cause each
Option granted hereunder to be clearly designated in the agreement evidencing
such option, at the time of grant, as to whether or not it is intended to
qualify as an Incentive Stock Option.

                                     - 8 -
<PAGE>
 
     10.  Execution of Shareholder's Agreement.  Options may only be exercised
hereunder by Optionees who have executed a Shareholder's Agreement substantially
in the form attached hereto as Exhibit "C" or such other form as the Board may
adopt from time to time.

     11.  Notices.  Whenever any notice is required or permitted hereunder, such
notice must be in writing and personally delivered or sent by mail.  Any notice
required or permitted to be delivered hereunder shall be deemed to be delivered
on the date which it is personally delivered, or, whether actually received or
not, on the third business day after it is deposited in the United States mail,
certified or registered, postage prepaid, addressed to the person who is to
receive it at the address which such person has theretofore specified by written
notice delivered in accordance herewith.  The Company or an Optionee may change,
at any time and from time to time, by written notice to the other, the address
which it or he had theretofore specified for receiving notices.  Until changed
in accordance herewith, the Company and each Optionee shall specify as its and
his address for receiving notices the address set forth in the option agreement
pertaining to the shares to which such notice relates.

     12.  Amendment or Discontinuance.  The Plan and any Option outstanding
hereunder may be amended or discontinued by the Board without the approval of
the shareholders of the Company, except that the Board may not, except as
expressly provided in the Plan, increase the aggregate number of shares which
may be issued under Options granted pursuant to the Plan and except that no
action may be taken by the Board, not expressly provided for herein, in
derogation of the vested rights of any Optionee under an Option previously
granted hereunder.

     13.  Effect of the Plan.  Neither the adoption of this Plan nor any action
of the Board shall be deemed to give any officer or employee any right to be
granted an option to purchase Common Stock of the Company or any of its
Subsidiaries, or any other rights except as may be evidenced by a stock option
agreement, or any amendment thereto, duly authorized by the Board and executed
on behalf of the Company and then only to the extent and on the terms and
conditions expressly set forth therein.

                                     - 9 -

     14.  Grant of Incentive Stock Options.  No Incentive Stock Option shall be
granted pursuant to this Plan after the expiration of ten years from the date of
the earlier of: (i) the date the Plan is adopted, or (ii) the date the Plan is
approved by the stockholders of the Company.

the terms and conditions upon which Awards may be made and exercised; (ii) to
determine the Participants to which Awards shall be made; (iii) to determine all

Awards made under the Plan shall not exceed 600,000 Shares, which may be in any
combination of Options, Restricted Stock, Restricted Stock Units, Performance
Shares, Bonus Shares, or Other Stock Unit Award.  Shares of Common Stock may be
available from the authorized but unissued Shares, Shares issued and reacquired

connection with the exercise of, or as other payment for, Awards under the Plan
shall reduce the number of Shares available for future Awards under the Plan.

or other Award granted under the Plan terminates, expires, or lapses for any
reason without having been exercised in accordance with its terms;  (ii) Shares

<PAGE>
 
     5.3  Delivery of Shares as Payment.  In the event a Participant pays for
any Option or other Award granted under the Plan through the delivery of
previously acquired shares of Common Stock, the number of shares of Common Stock
available for Awards under the Plan shall be increased by the number of shares
surrendered by the Participant.

     5.4  Capital Adjustments.  The number and class of Shares subject to each
outstanding Award, the Option Price and the aggregate number, type and class of
Shares for which Awards thereafter may be made shall be subject to adjustment,
if any, as the Committee deems appropriate, based on the occurrence of a number
of specified and non-specified events.  Such specified events are discussed in
this Section 5.4, but such discussion is not intended to provide an exhaustive
list of such events which may necessitate adjustments.

     (a)  If the outstanding Shares are increased, decreased or exchanged
          through merger, consolidation, sale of all or substantially all of the
          property of the Company, reorganization, recapitalization,
          reclassification, stock dividend, stock split, reverse stock split or
          other distribution in respect to such Shares, for a different number
          or type of Shares, or if additional Shares or new or different Shares
          are distributed with respect to such Shares, an appropriate and
          proportionate adjustment shall be made in: (i) the maximum number of
          shares of Stock available for the Plan as provided in Section 5.1
          herein; (ii) the type of shares or other securities available for the
          Plan; (iii) the number of shares of Stock subject to any then
          outstanding Awards under the Plan; and (iv) the price (including
          Exercise Price) for each share of Stock (or other kind of shares or
          securities) subject to then outstanding Awards, but without change in
          the aggregate purchase price as to which such Options remain
          exercisable or Restricted Stock releasable.

     (b)  In the event other events not specified above in this Section 5.4,
          such as any extraordinary cash dividend, split-up, reverse split,
          spin-off, combination, exchange of shares, warrants or rights offering
          to purchase Common Stock, or other similar corporate event, affect the
          Common Stock such that an adjustment is necessary to maintain the
          benefits or potential benefits intended to be provided under this
          Plan, then the Committee in its discretion may make adjustments to any
          or all of: (i) the number and type of shares which thereafter may be
          optioned and sold or awarded or made subject to Stock Appreciation
          Rights under the Plan; (ii) the grant, exercise or conversion price of
          any Award made under the Plan thereafter; and (iii) the number and
          price (including Exercise Price) of each share of Stock (or other kind
          of shares or securities) subject to the then outstanding Awards.

     (c)  Any adjustment made by the Committee pursuant to the provisions of
          this Section 5.4 shall be final, binding and conclusive.  A notice of
          such adjustment, including identification of the event causing such
          adjustment, the calculation method of such adjustment, and the change
          in price and the number of shares of Stock, or securities, 

                                       7
<PAGE>
 
          cash or property purchasable subject to each Award shall be sent to
          each Participant. No fractional interests shall be issued under the
          Plan based on such adjustments.

SECTION 6.  STOCK OPTIONS

       6.1  Grant of Stock Options.  Subject to the terms and provisions of the
Plan and applicable law, the Committee, at any time and from time to time, may
grant Options to Key Employees as it shall determine.  The Committee shall have
sole and complete discretion in determining the type of Option granted, the
Option Price (as hereinafter defined), the duration of the Option, the number of
Shares to which an Option pertains, any conditions imposed upon the
exercisability or the transferability of the Options, including vesting
conditions, the conditions under which the Option may be terminated, and any
such other provisions as may be warranted to comply with the law or rules of any
securities trading system or stock exchange.  Each Option grant shall have such
specified terms and conditions detailed in an Option Agreement.  The Option
Agreement shall specify whether the Option is intended to be an Incentive Stock
Option or a Nonqualified Stock Option.

       6.2  Option Price.  The exercise price per share of Stock covered by an
Option ("Option Price") shall be determined on the Grant Date by the Committee;
provided that the Option Price of an Option intended to constitute an Incentive
Stock Option shall not be less than 100% of the Fair Market Value of the Common
Stock on the Grant Date.

       6.3  Exercisability.  Options granted under the Plan shall be exercisable
at such times and be subject to such restrictions and conditions as the
Committee shall determine, which will be specified in the Option Agreement and
need not be the same for each Participant. However, no Option granted under the
Plan may be exercisable after the expiration of ten years from the Grant Date.

       6.4  Method of Exercise.  Options shall be exercised by the delivery of a
written notice from the Participant to the Company in a form prescribed by the
Committee setting forth the number of Shares with respect to which the Option is
to be exercised, accompanied by full payment or provision for full payment for
the Shares.  The Option Price shall be payable to the Company in full in cash,
or its equivalent, or by delivery of Shares of Stock (not subject to any
security interest or pledge) having a Fair Market Value at the time of exercise
equal to the exercise price of the Shares, or by a combination of the foregoing.
As soon as practicable, after receipt of written notice and full payment of the
Option Price, the Company shall deliver to the Participant a stock certificate,
issued in the Participant's name, evidencing the number of Shares with respect
to which the Option was exercised.

Appreciation Rights, Stock Appreciation Rights in tandem with an Option, or
Stock Appreciation Rights in addition to an Option. Stock Appreciation Rights
granted in tandem with an Option or in addition to an Option may be granted at
the time of the Option or at a later time. No Stock Appreciation Rights granted
under the Plan may be exercisable after the expiration of ten years from the
Grant Date.

       7.2  Price.  The exercise price of each Stock Appreciation Right shall be
determined at the time of grant by the Committee, subject to the limitation that
the grant price shall not be less than 100% of Fair Market Value of the Common
Stock on the Grant Date.

       7.3  Exercise.  Stock Appreciation Rights shall be exercised by the
delivery of a written notice from the Participant to the Company in a form
prescribed by the Committee.  Upon such exercise, the Participant shall be
entitled to receive an amount equal to the excess of the Fair Market Value of a
Share over the grant price thereof on the date of exercise of the Stock
Appreciation Right multiplied by the number of Shares for which the Stock
Appreciation Right was granted.

       7.4  Payment.  Payment upon exercise of the Stock Appreciation Right
shall be in the amount of the full exercise price therefor, and shall be made in
the form of cash, cash installments, Shares of Common Stock, or a combination
thereof, as determined in the sole and complete discretion of the Committee.
However, if any payment in the form of Shares results in a fractional share,
such payment for the fractional share shall be made in cash.

the Plan and applicable law, the Committee, at any time and from time to time,

satisfied prior to removal of the restriction, the number of Shares of
Restricted Stock or Restricted Stock Units granted, payment terms for each such
Award (e.g. whether the Award will be paid in shares of Stock, cash or a
combination thereof, and whether payment will be in a lump sum or installments),

based on any Performance Criteria, including, but not limited to, absolute or

whose name Restricted Stock is granted under the Plan may exercise full voting
rights with respect to those shares.

       8.6  Dividends and Other Distributions.  During the Period of
Restriction, Participants in whose name Restricted Stock is granted under the
Plan shall be entitled to receive all dividends and other distributions paid
with respect to those Shares. If any such dividends or distributions are paid in

and forfeitability as the Restricted Stock with respect to which they were
distributed.

Participant.

       9.2  Value of Performance Awards.  The Committee shall determine the
number and value of Performance Units or Performance Shares granted to each

in its discretion for each Participant who is granted a Performance Award. The

the Performance Unit or Performance Share to the Participant. Such Performance
Criteria may be particular to a Participant, may relate to the performance of
the Company or Subsidiary which employs him or her, or any combination of the
foregoing. The Performance Criteria may be based on achievement of financial
statement objectives, or any other objectives established by the Committee. The
Performance Criteria may be absolute in their terms or measured against, or in
relationship to, other companies comparably, similarly or otherwise situated.
The terms and conditions of each Performance Award will be set forth in an Award

SECTION 10.  BONUS STOCK

       Subject to the terms and provisions of the Plan and applicable law, the
Committee may, at any time and from time to time, award shares of Bonus Stock to
participants under the Plan without cash consideration.  The Committee shall
determine and indicate in the related Award Agreement whether such shares of
Bonus Stock shall be unencumbered of any restrictions (other than those which
the Committee deems necessary or advisable to comply with law) or shall be
subject to restrictions and limitations similar to those referred to in Section
9.  In the event the Committee assigns any restrictions on the shares of Bonus
Stock, then such shares shall be subject to at least the following restrictions:

       (a)  No Shares of Bonus Stock may be sold, transferred, pledged, assigned
            or otherwise alienated or hypothecated if such Shares are subject to
            restrictions which have not lapsed or been satisfied.

       (b)  If any condition of vesting of the shares of Bonus Stock are not
            met, all such Shares subject to such vesting shall be delivered to
            the Company (in a manner determined by the Committee) within 60 days
            of the failure to meet such conditions without any payment from the

Stock or other securities.  The value of each such Award shall be based, in
whole or in part, on the value of the underlying Common Stock on the Grant Date.
The Committee, in its sole and complete discretion, may determine that an Award,
either in the form of a Stock Unit Award under this Section 11 or as an Award
granted pursuant to Sections 6 through 10, may provide to the Participant (i)
dividends or dividend equivalents (payable on a current or deferred basis) and
(ii) cash payments in lieu of or in addition to an Award.  Subject to the
provisions of the Plan, the Committee, in its sole and complete discretion,
shall determine the terms, restrictions, conditions, vesting requirements, and
payment rules of the Award.  The Award Agreement shall specify the 

                                      11

rules of each Award as determined by the Committee. However, each Stock Unit

            representative.

       (c)  Stock Unit Awards may require the payment of cash consideration by
            the Participant in receipt of the Award or provide that the Award,
            and any Common Stock or other securities issued in conjunction with
            the Award, be delivered without the payment of cash consideration.

       (d)  The Committee, in its sole and complete discretion, may establish
            certain Performance Criteria that may relate in whole or in part to
            receipt of Stock Unit Awards.

       (e)  Stock Unit Awards may be subject to a deferred payment schedule
            and/or vesting over a specified period.

       The Plan shall terminate December 31, 2006; however, all Awards made
prior to, and which are outstanding on such date, shall remain valid in
accordance with their terms and conditions.

       14.2  Withholding.  The Company shall have the right to deduct or
withhold, or require a Participant to remit to the Company, any taxes required
by law to be withheld from Awards made under this Plan. In the event an Award is
paid in the form of Common Stock, the Committee may require the Participant to
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
corresponding Award Agreement provided in writing to the Participant, which
shall specify the terms, conditions and any rules applicable to the Award.

       14.4  Nontransferability.  Except with respect to Nonqualified Stock
Options, no Award granted under the Plan may be sold, transferred, pledged,
assigned or otherwise alienated or hypothecated, except by will or the laws of
descent and distribution.  Further, no lien, obligation, or liability of the
Participant may be assigned to any right or interest of any Participant in an
Award under this Plan.

       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
stockholder of the Company nor have any rights as such with respect to any
shares of Common Stock to be provided under the Plan until he or she has become
the holder of such shares.

       14.7  Construction of the Plan.  The Plan and all Agreements shall be
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

                                      14
<PAGE>
 
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.

       14.10  Exemption from Computation of Compensation for Other Purposes.
By acceptance of an applicable Award under this Plan, subject to the conditions
of such Award, each Participant shall be considered in agreement that all shares
of Stock sold or awarded and all Options granted under this Plan shall be
considered extraordinary, special incentive compensation and will not be
included as "earnings," "wages," "salary" or "compensation" in any pension,
welfare, life insurance, or other employee benefit arrangement of the Company.

       14.11  Legend.  In its sole and complete discretion, the Committee may
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
compensated employees.

NetSolve/(R)/, Incorporated
12331 Riata Trace Parkway
Austin, Texas  78727



Gentlemen:

         The following confirms an agreement between me and NetSolve(R),
Incorporated, a Delaware corporation (the "Company", which term includes the
Company's subsidiaries), which is a material part of the consideration for my
employment by the Company:

         1.    I recognize that the Company is engaged in a continuous program
of research, development and production respecting its business, present and
future, including fields generally related to its business and that the Company
possesses and will continue to possess information that has been created,
discovered, developed or otherwise become known to the Company (including,
without limitation, information created by, discovered or developed by, or made
known to me during the period of or arising out of my employment by the Company)
and/or in which property rights have been assigned or otherwise conveyed to the
Company, which information has commercial value in the business in which the
Company is engaged. All of the aforementioned information is hereinafter called
"NetSolve Proprietary Information." By way of illustration, but not limitation,
NetSolve Proprietary Information includes trade secrets, designs, technological
advancements, configurations, processes, formulas, data and know-how, software
programs, manuals, guides, improvements, inventions, techniques, marketing
plans, strategies, forecasts, computer programs, financial information,
personnel information, copyrightable material and customer and prospective
customer lists, belonging to the Company (whether or not reduced to writing and
whether or not patentable or protectable by copyright). Notwithstanding anything
to the contrary set forth herein, the restrictions regarding the use and
disclosure of NetSolve Proprietary Information and Inventions (as hereinafter
defined) set forth herein shall not apply if the same:

         (a)   is in the public domain or already in my possession without
               restriction at the time the same came into my possession;

         (b)   is used or disclosed with the prior written approval of the 
               Company; or

         (c)   is made available by the Company to a third party on an
               unrestricted, non-confidential basis.

                                       1
<PAGE>
 
         2.    I understand that my employment creates a relationship of
confidence and trust between me and the Company with respect to any information,
materials, or inventions:

         (a)   applicable to the business of the Company; or

         (b)   applicable to the business of any client, customer, vendor, or
               other third party, which may be made known to me by the Company
               or by any client, customer, vendor, or other third party, or
               learned by me during the period of my employment.

         3.    In consideration of my employment by the Company and the
compensation received by me from the Company from time to time, I hereby agree
as follows:

         (a)   Unless required by the Company in connection with my employment
               or with the Company's express written consent, I will not, either
               during my employment or afterwards, directly or indirectly, use
               or disclose for my own benefit or the benefit of another any
               NetSolve Proprietary Information, including trade secrets or
               confidential information, whether or not the information is
               acquired, learned, attained, or developed by myself alone or in
               conjunction with others. I make the same pledge with regard to
               the proprietary information of the Company's customer,
               contractors, or others with whom the Company has a business
               relationship.

         (b)   All NetSolve Proprietary Information shall be the sole property
               of the Company and its assigns, and the Company and its assigns
               shall be the sole owner of all patents, copyrights, and other
               rights in connection therewith. I hereby assign to the Company
               any rights I may have or acquire in such NetSolve Proprietary
               Information. At all times, both during my employment by the
               Company and after its termination, I will keep in confidence and
               trust all NetSolve Proprietary Information, and I will not use or
               disclose any NetSolve Proprietary Information or anything
               relating to it without the written consent of the Company, except
               as may be necessary during my employment in the ordinary course
               of performing my duties to the Company.

         (c)   All documents, records, apparatus, equipment and other physical
               property, whether or not pertaining to NetSolve Proprietary
               Information, furnished to me by the Company or produced by myself
               or others in connection with my employment shall be and remain
               the sole property of the Company and shall be returned to it
               immediately as and when requested by the Company. Even if the
               Company does not so request, I shall promptly return and deliver
               all such property upon termination of my employment by me or by
               the Company for any reason and I will not take with me any such
               property or any reproduction of such property upon such
               termination.

         (d)   I will promptly disclose to the Company, or any persons
               designated by it, all improvements , inventions, formulas, ideas,
               designs, configurations, processes, techniques, know-how and
               data, whether or not patentable, made or conceived or reduced to
               practice or learned by me, either alone or jointly with others,
               during the term of m employment (all said improvements,
               inventions, formulas, ideas, designs, configurations, processes,
               techniques, 

                                       2
<PAGE>
 
               know-how and data shall be hereinafter collectively called
               "Inventions").

         (e)   I agree that all Inventions which I develop during my employment
               with the Company (in whole or in part, either alone or jointly
               with others) and (i) used equipment, supplies, facilities of the
               Company or NetSolve Proprietary Information, or (ii) used the
               hours for which I was compensated by the Company, or (iii) which
               relate to the business of the Company or to its actual research
               and development or (iv) which result, in whole or in part, from
               work performed by me for the Company, shall be the sole property
               of the Company and its assigns, and the Company and its assigns
               shall be the sole owner of all patents, copyrights and other
               rights in connection therewith. I hereby assign to the Company
               any rights I may have or acquire in such Inventions. I further
               agree as to all such Inventions and improvements to assist the
               Company in every proper way (but at the Company's expense) to
               obtain and from time to time enforce patents, copyrights or other
               rights on said Inventions and improvements in any and all
               countries, and to that end I will execute all documents for use
               in applying for and obtaining such patents and copyrights thereon
               and enforcing same, as the Company may desire, together with any
               assignments thereof to the Company or persons designated by it.
               My obligation to assis the Company in obtaining and enforcing
               patents, copyrights or other rights for such Inventions and
               improvements in any and all countries shall continue beyond the
               termination of my employment, but the Company shall compensate me
               at a reasonable rate after such termination for time actually
               spent by me at the Company's request on such assistance and
               reimburse me for any expenses reasonably incurred by me in
               connection therewith. In the event that the Company is unable for
               any reason whatsoever to secure my signature to any lawful and
               necessary document required to apply for or execute any patent,
               copyright or other application with respect to such Inventions
               and improvements (including renewals, extensions, continuations,
               divisions or continuations in whole or in part thereof), I hereby
               irrevocably designate and appoint the Company and its duly
               authorized officers and agents, as my agents and attorneys- in-
               fact to act for and in my behalf and instead of me, to execute
               and file any such application and to do all other lawfully
               permitted acts to further the prosecution and issuance of
               patents, copyrights or other rights thereon with the same legal
               force and effect as if executed by me.

         (f)   As a matter of record I attach hereto a complete list of all
               Inventions or improvements relevant to the subject matter of my
               employment by the Company which have been made or conceived or
               first reduced to practice by me alone or jointly with others
               prior to my employment with the Company that I desire to remove
               from the operation of this Agreement, and I covenant that such
               list is complete. If no such list is attached to this Agreement,
               I represent that I have no such Inventions and improvements at
               the time of signing this Agreement.

         (g)   I represent that my performance of all the terms of this
               Agreement will not breach any agreement to keep in confidence
               proprietary information acquired by me in confidence or in trust
               prior to my employment by the Company. I have not entered into,
               and I agree I will not enter into, any agreement (either 

                                       3
<PAGE>
 
               written or oral) in conflict herewith.

         (h)   I represent that execution of this Agreement, my employment with
               the Company and my performance of my proposed duties to the
               Company will not violate any obligations I may have to any former
               employer.

         4.    As an independent covenant, I further agree that, without the
express written consent of the Company, I will refrain, during my employment by
the Company and for a period of six (6) months thereafter, from consulting with
or otherwise associating with or working for any business which directly
competes with the business of the Company and from otherwise planning the
formation of a new business or enterprise which proposes to directly compete
with the business of the Company. If any such activities are engaged in by me,
after having obtained the written consent of the Company, I agree to promptly
disclose to the Company the full nature and extent of such activities.

         5.    If any portion of this Agreement is found by a court of competent
jurisdiction to be void or unenforceable, that portion shall be deemed to be
reformed to the extent necessary to cause such portion to be enforceable and the
same shall not affect the remainder of the Agreement, which shall be given full
force and effect without regard to the invalid or unenforceable portions.

         6.    I understand and agree that, in the event of a breach or
threatened breach by me of any of the provisions of this Agreement, damages will
not provide a sufficient remedy to the Company, and, accordingly, the Company
shall have the right, in addition to any other right or remedy of any nature,
whether at law or in equity, to seek injunctive or other equitable relief from
any court of competent jurisdiction, without notice or the posting of any bond,
and I hereby consent to the entry of an order granting such relief.

         7.    This Agreement shall be effective as of the first day of my
employment by the Company.

         8.    This Agreement shall be binding upon me, my heirs, executors,
assigns, and administrators and shall inure to the benefit of the Company, its
successors and assigns.

Mr. Craig S. Tysdal
380 Bryan Drive
Danville  CA  94526

Dear Craig:

On behalf of all my colleagues on the SNS Board of Directors, as well as the
officers of SNS, I am pleased to present our formal offer to you to become SNS's
new President and Chief Executive Officer, and member of the Board of Directors.

SNS's Directors and senior staff have all enjoyed getting to know you, and we
are unanimous in our enthusiastic support of this offer -- and we all look
forward very much to welcoming you, Janet and Cindy to SNS and to Austin.  All
of us have been impressed with your personal stature, your skills, and your
achievements, and by how well you fit the profile we established.  We are
convinced that you are very well qualified to lead SNS to major growth and
success.  We also believe, as I know you do, that becoming President and CEO of
SNS is an excellent opportunity for you to lever your many talents, experiences
and achievements, and to attain your own career and financial goals.

We have given careful thought to compensation arrangements that would be
appropriate to your professional stature, to SNS's stage of development, and to
SNS precedents and policies. Accordingly:

1.   Your initial base salary as President and CEO will be $12,500 per month,
     and it will be reviewed annually by the Board in September of each year,
     beginning with September 1994.

2.   You will be granted, upon your employment, a stock option in the amount of
     500,000 shares of SNS common stock, which will vest over four years -- 25%
     after twelve months and 6.25% per quarter thereafter.  Those 500,000 shares
     are equivalent to 4.488% of the fully diluted common and common equivalent
     shares after an addition of 500,000 shares to the SNS Employee Stock Option
     Plan, which addition must be submitted to the shareholders of the Company
     for their approval.  SNS will reserve the right of first refusal on your
     stock, should you desire to make any transfer of ownership, for as long as
     SNS remains a privately-held corporation.

                                                                          Page 2



3.   Should SNS be sold, all of your unvested shares -- should there then be any
     -- will become immediately vested.

4.   Responsive to your desire to take up residence with your family in Austin
     as soon as possible, SNS will reimburse you the ordinary and reasonable
     costs of moving some of your personal and household goods, including two
     cars, to Austin at the beginning of your employment.  Furthermore, for the
     first six months of your employment or until you acquire permanent housing,
     whichever comes first, you will receive an interim housing allowance of
     $2,000 per month, grossed up as required for tax purposes.

5.   To assist Janet and you in finding a suitable new home in Austin, SNS will
     reimburse the cost of up to two, three-day househunting trips for you,
     Janet and Cindy.

6.   Regarding your permanent relocation, including the sale of your California
     residence and purchase of a new home in Austin, SNS will reimburse you the
     ordinary and reasonable costs of moving your remaining household items.  To
     partially compensate for your other expenses related to such a move, SNS
     will reimburse other documented expenses up to a maximum of $30,000.

7.   As an SNS employee, you will be eligible to participate in all benefit
     plans sponsored by SNS as in effect from time to time, which plans may be
     changed or amended in the future, and currently include medical, dental,
     and disability plans (see benefits outline enclosed).  In addition, SNS
     will pay for a $25,000 term life insurance policy in favor of your
     beneficiary(s), and you may participate in SNS's 401K plan.

8.   It is mutually understood and agreed that, should your employment be
     terminated by SNS, other than for "cause" (as hereinafter defined), you
     shall be entitled to receive a severance payment equal to six times your
     monthly base salary then in effect.

9.   Termination of employment shall be for "cause" if in the reasonable opinion
     of SNS's Board of Directors: you breach or neglect the duties which you are
     required to perform; commit any material act of dishonesty, fraud,
     misrepresentation, or other act of moral turpitude; are guilty of gross
     carelessness or misconduct; fail to obey the lawful direction of SNS's
     Board of Directors; or act in any way that results in direct, substantial
     and adverse effect on SNS's reputation.

In accordance with U.S. law, this offer is conditional upon satisfactory proof
of U.S. citizenship or other eligibility for employment, as required by the
Immigration Reform and Control Act of 1986.  Texas common law provides for
employment at will and accordingly, employment may be terminated by either
party, with or without cause, at any time upon notice to the other.

Craig, we look forward to your prompt acceptance of our offer, and to your

Boynton Beach, FL 33435

Dear Chris,

On behalf of NetSolve Incorporated, I am pleased to offer you a position as Vice
President of Sales, reporting to me.  We would like you to commence work on
Monday, March 2, 1998, in our offices at 9130 Jollyville Road, 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 $12,500 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.

You will be eligible for commissions and bonuses in accordance with the current
NetSolve Sales Compensation Plan.  This plan is subject to modification, in
whole or in part, and your participation, as well as the benefits available
thereunder, are subject to the terms of the plan document.  You will be started
on this plan effective April 1, 1998.  The target variable compensation for the
plan at quota will be $100,000/plan year.  A non-recoverable draw against
commissions of $5,000.00 per month will be provided during the first 12 months
of your employment.

In addition to salary, the Company also offers certain employee benefits,
including group medical and dental insurance, 401(k) Plan, 125 Cafeteria Plan,
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.  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.

At the next Board of Director's meeting, we will recommend that you be issued
Incentive Stock Options to purchase 120,000 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 $60,500.  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.
Should you terminate employment prior to completing 12 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 sincerely hope that you will join our team, and I look forward to working with
you.

                            STOCK OPTION AGREEMENT

      THIS STOCK OPTION AGREEMENT (the "Agreement) is made and entered into as
of this 27th day of July, 1989, by and between SOUTHWEST NETWORK SERVICES, INC.,
a Delaware corporation (the "Company"), and Howard D. Wolfe, a director of the
Company ("Optionee").

      WHEREAS, in consideration and recognition of his contributions to the
Company as a director, the Company desires to afford Optionee an opportunity to
purchase shares of its Common Stock, $.01 par value per share (the "Common
Stock"), under the terms and conditions provided herein.

      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 terms and provisions hereof, an option (the "Option") to purchase all or any
part of 40,000 shares of the Common Stock of the Company on the terms and
conditions herein set forth.

      2.    Purchase Price.  The purchase price of each share of Common Stock
subject to this Option shall be $.06 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 or partly in cash or such
check and partly in such stock.  The value of shares of Common Stock delivered
in connection with the payment of the option price shall be the fair market
value of such shares as determined by the Board of Directors of the Company (the
"Board") and such determinations shall be binding upon the Optionee.  No shares
may be issued until full payment of the purchase 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.

      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, 
<PAGE>
 
is necessary or desirable as a condition of, or in connection with, such
exercise or the delivery or 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 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 Company 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 or its subsidiaries for
any reason other than his death, retirement or permanent disability, any part of
the Option granted hereunder which has not been exercised by the date of such
cessation shall immediately terminate on the date of such cessation. In the
event that Optionee's directorship with the Company or its subsidiary shall
terminate by reason of his retirement or permanent disability, 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
date of its expiration or three (3) months after the date of such termination,
whichever occurs first.

      8.    Death of Optionee.  If Optionee dies prior to the termination of his
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.

                                     - 2 -
<PAGE>
 
      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, share combination,
exchange of shares, recapitalization, merger, consolidation, separation,
reorganization, liquidation or the like of or by the Company.  Decisions by the
Board 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 shareholder with respect to any shares covered hereby
until the date of the issuance of one 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 continued right of service or tenure as a
director of the Company or any additional rights other than as expressly
provided for herein.  There is no obligation upon Optionee to exercise this
Option or any part thereof.

      11.   Non-Qualified Stock Option.  This Option is not intended to qualify
as an "incentive stock option" under the Internal Revenue Code of 1986, as
amended, and applicable regulations and rulings promulgated thereunder, and
shall not be so construed.  This Option is not intended to be subject to, or
granted under or pursuant to, the Company's 1988 Stock Option Plan, and shall
not be so construed.

      12.   Purchaser Deemed to be a Consultant.  As a director of the Company,
Purchaser shall be deemed to be a consultant to the Company for purposes of
Section 6(c)(ii) of the Company's Designation of the Series A Preferred Stock,
Section 6(c)(ii) of the Company's Designation of the Series B Preferred Stock
and Section 9.5(d) of that certain Series B Preferred Stock Purchase Agreement
dated as of October 18, 1988 by and among the Company and the Investors (as
defined therein).

      13.   Amendment.  The Board 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 Board, 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 Board shall be final and binding on
Optionee.

      14.   Shareholder's Agreement.  The exercise of this Option is expressly
conditioned upon the contemporaneous execution by the Optionee and the Company
of a Shareholder's Agreement, substantially in the form attached hereto as
Exhibit "A".  All rights of the Optionee and Optionee's heirs, successors and
assigns shall be determined by such agreement and Optionee and Optionee and his
heirs, successors and assigns shall be bound thereby.

      IN WITNESS WHEREOF, Southwest Network Services, Inc. and Howard D. Wolfe,
Optionee, have executed this Stock Option Agreement as of the date first above
written.

     consultant to the Company for any reason or no reason with or without
     cause.

     3.   Rights as Stockholder; Escrow.

          (a)  Subject to the terms and conditions of this Agreement, the
     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 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, the Purchaser agrees to vote
     the Shares in accordance with the terms of Section 8 of the Stock Purchase
     Agreement (the terms of which, as they may be amended from time to time
     pursuant to such agreement, are incorporated herein by reference) as though
     he 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. Within five (5)
     days after 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, recapitalization 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;

          (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.

                                     - 3 -
<PAGE>
 
          (b)  At any time within 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.

          (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 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 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 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 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 

                                     - 4 -
<PAGE>
 
     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.

          (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.

                                     - 5 -
<PAGE>
 
     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 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. Except as
provided in Section 7.3 of the Stock Purchase Agreement, 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.  Purchaser Deemed to be a Consultant. As a director of the Company,
Purchaser shall be deemed to be a consultant to the Company for purposes of
Section 6(c)(ii) of the Company's Designation of the Series A Preferred Stock,
Section 6(c)(ii) of the Company's Designation of the Series B Preferred Stock
and Section 9.5(d) of that certain Series B Preferred Stock Purchase

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.
