                                    SUMMARY

     This summary highlights information contained elsewhere in this prospectus.
You should read the entire prospectus, including the financial statements and
related notes, before deciding to invest in shares of our common stock.

                                XCARE.NET, INC.

     XCare.net, Inc. is a leading provider of Internet-based,
business-to-business connectivity, information exchange and electronic commerce
solutions for health care. We have developed an Internet-based information and
transaction technology platform, which we call the XCare.net platform. Using the
XCare.net platform, we connect health care participants together into a
community structure and deliver applications, services and electronic commerce
product offerings that are designed to improve process efficiencies, reduce
administrative costs and create new revenue opportunities for our customers. The
XCare.net platform has been adopted by health care providers, payers and
suppliers. In addition, we have entered into strategic relationships that we
believe will enhance our portfolio of solutions, provide important specialized
industry expertise to us and our customers and create additional revenue
sources.

     We believe that the XCare.net platform is the first infrastructure based on
extensible mark-up language, or XML, using the Topic Navigation Mapping standard
that is specifically tailored to meet the demands of health care industry
participants. We take advantage of the benefits of both XML and Topic Navigation
Mapping technologies to process data previously trapped in legacy systems, allow
for automation of health care processes and integrate a wide variety of health
care data including audio, video and text.

                               MARKET OPPORTUNITY

     The health care market is highly fragmented through geographic dispersion,
a large number of participants and significant differences in technology
infrastructure. Furthermore, health care is delivered in a marketplace which has
become increasingly complex given the transition to managed care, the data-
intensive nature of health care transactions, the lack of standard data formats,
the complicated procurement process and the pervasiveness of government
regulation. As a result of this fragmentation and complexity, health care market
participants are unable to cost-effectively manage, communicate and exchange
information in real-time.

     The Internet has emerged as the fastest growing communication medium in
history. The ubiquitous nature, low cost and scalability of the Internet have
created new opportunities for conducting secure commerce. Recently, the
widespread adoption of intranets and the acceptance of the Internet as a
business communications platform have created a foundation for
business-to-business electronic commerce that should enable organizations to
streamline complex processes, lower costs and improve productivity.

     Although the Internet can speed and streamline transactions, we believe
that current, Internet-based health care solutions are significantly limited in
their ability to search, structure, integrate and filter vast amounts of
disparate data and dynamically customize and display information in contexts
relevant to particular users. These limitations are particularly critical in the
health care industry, where information and transaction connectivity among all
participants is necessary to reduce process inefficiencies and costs.

                                    SOLUTION

     We believe that the XCare.net platform and our solutions can reduce
administrative and transaction inefficiencies and simplify the way business is
conducted in health care, which may ultimately enhance

                                        1
<PAGE>   5

the quality of health care delivery in the U.S. We believe that our solutions
have the following advantages:

     - Use of new standard for information exchange. The XCare.net platform is
       based on XML, which we believe can process data trapped in legacy
       systems, automate health care processes, integrate a wide array of health
       care data and dynamically retrieve and update data in a manner that can
       be customized for each health care participant.

     - Disciplined approach to creating customer solutions. We have developed a
       step-by-step approach to assist our customers to envision, evaluate and
       execute an Internet-based, health care strategy.

     - Complete, turnkey solutions. Our solutions, which are delivered through a
       low cost, low maintenance platform, are designed to provide a
       comprehensive set of applications, services and product offerings while
       preserving previous technology investments by integrating diverse
       multimedia content, including data and information from legacy systems.

     - Value-added Solution Channels. Our business model is based on a
       multi-faceted network of collaborative relationships, which we call
       Solution Channels, among our company, our customers and our vendors to
       leverage our customers' and vendors' core competencies to promote the
       exchange of health care related services.

                                    STRATEGY

     Our objective is to become the leading provider of health care solutions
for Internet-based, business-to-business connectivity, information exchange and
electronic commerce. Our strategy is based on five main elements. First, we
believe that our Solution Channels represent an opportunity for deploying new
applications, services and electronic commerce product offerings that are
developed by us or obtained through customer and vendor relationships. Second,
we intend to pursue payer/third-party administrator and at-risk provider
customers, which are well positioned to influence and drive change in health
care processes. Third, as Internet strategies in the health care industry evolve
and new relationships between organizations develop, we will seek to identify
new application development opportunities. Fourth, we plan to identify key
functions that are critical to particular industry participants and develop
solutions, services and products supporting these functions. Fifth, we are
aggressively pursuing strategic relationships with leaders in key health care
industry segments to increase our portfolio of applications, services and
product offerings, increase the scope of the community of users of our
technology platform and provide specialized industry expertise for new
solutions.

                                  OUR HISTORY

     We were incorporated in Delaware in March 1989 under the name Reilly Dike
Dosher Corporation, Inc. In December 1996, we changed our name to MPower
Solutions, Inc. In April 1999, we changed our name to XCare.net, Inc. We have
historically derived a significant portion of our revenue from sales of
mainframe and client-server software for managed health care systems and from
providing services to health care organizations seeking to outsource
administrative functions. Beginning in mid-1998, we began to focus on
Internet-based health care solutions. We intend to derive an increasing portion
of our future revenue from our Internet-based applications, services and product
offerings. Our principal executive office is located at 6400 S. Fiddler's Green
Circle, Suite 540, Englewood, CO 80111, and our telephone number at that office
is (303) 488-2019. Our World Wide Web address is www.xcare.net. Information
contained in our Web site does not constitute part of this prospectus.

     The number of shares of our common stock to be outstanding after this
offering is based on shares outstanding as of September 30, 1999, but does not
reflect a reverse stock split we intend to effect prior to this offering. It
excludes 14,914,921 shares issuable upon exercise of outstanding options at
September 30, 1999, with a weighted average exercise price of $0.13 per share,
5,413,454 shares reserved for future issuance under our stock plan, and
5,250,000 shares reserved for future issuance under our director plan and
employee stock purchase plan, both of which become effective upon the closing of
the offering. See "Capitalization," "Management -- Employee Benefit Plans" and
notes 4, 6 and 9 of notes to the financial statements.

     Generally, unless otherwise indicated in this prospectus, the number of
shares of common stock to be outstanding after the offering, pro forma and pro
forma as adjusted information gives effect to the conversion of all outstanding
convertible preferred stock to common stock, including convertible preferred
stock issuable upon the assumed exercise of all outstanding convertible
preferred stock warrants, and the assumed exercise of all outstanding common
stock warrants with exercise prices below an assumed initial public offering
price. Information in this prospectus also assumes no exercise of the
underwriters' over-allotment option.

     - During 1996, a major customer terminated its contract with us and paid
       $2.3 million to settle all claims arising under the termination. During
       1997, another major customer terminated its contract with us and paid
       $250,000 to settle all claims associated with the termination. These
       amounts are included above in total other income (expense).

     - As a result of the contract terminations referred to above, during 1997
       we abandoned an operating lease and incurred impairment charges for
       related fixed assets aggregating $887,000. This amount is included above
       in total costs and expenses.

     - Prior to January 1, 1996, XCare.net was an S corporation for federal and
       state income tax purposes, and accordingly, our income was taxed directly
       to our stockholders. Pro forma income before income taxes, pro forma net
       income and pro forma net income per common share for the years ended
       December 31, 1994 and 1995 give effect to pro forma adjustments that
       reflect the estimated federal and state income taxes that would have been
       recorded if XCare.net had been a C corporation prior to January 1, 1996.

                                  RISK FACTORS

     You should carefully consider these risk factors, together with all of the
other information included in this prospectus, before you decide whether to
purchase shares of our common stock. The risks set out below may not be
exhaustive. If any of the following risks actually occur, our business,
financial condition or results of operations could be harmed, the value of our
common stock could decline and you may lose all or part of your investment.

OUR BUSINESS AND PROSPECTS ARE DIFFICULT TO EVALUATE BECAUSE WE ARE IN A
TRANSITIONAL STAGE OF DEVELOPMENT

     It is difficult to evaluate our business and our prospects because our
business model is new and unproven. We commenced operations in March 1989, but
we did not begin focusing on Internet-based health care solutions until early
1999. As a result, we are prone to the risks and difficulties frequently
encountered by early stage companies, particularly companies in new and rapidly
evolving technology-related markets. We have historically derived a significant
portion of our revenue from sales of maintenance and client/server software for
managed health care systems and from providing services to health care
organizations seeking to outsource administrative functions. We intend to derive
an increasing portion of our future revenue from our Internet-based
applications, services and product offerings. In addition, due to our limited
operating history in the Internet-based health care market, it is difficult for
us to predict with any accuracy our future results of operations. For example,
we cannot accurately forecast expenses based on our historical results because
our experience in our current market is limited, and we are required to forecast
expenses in part on future revenue projections. The provision of services using
Internet technology in the health care industry is a developing business that is
inherently riskier than business in industries where companies have established
operating histories. Accordingly, we believe that our historical financial
results are not necessarily indicative of our future financial performance.

WE HAVE INCURRED LOSSES SINCE CHANGING OUR FOCUS TO INTERNET-BASED SOLUTIONS AND
WE MAY NOT BE ABLE TO ACHIEVE OR SUSTAIN PROFITABILITY

     We incurred net losses and losses from operations for the six months ended
June 30, 1999 and the years ended December 31, 1998 and 1997. As of June 30,
1999, we had an accumulated deficit of approximately $12.1 million. Since we
began developing and marketing our Internet-based health care products and
services in early 1999, we have funded our business primarily by borrowing funds
and from the sale of our stock, not from cash generated by our business. We
expect to continue to incur significant sales and marketing, research and
development and general and administrative expenses. As a result, we will
experience losses and negative cash flows for the foreseeable future. Factors
which may prevent us from achieving or maintaining profitability and cause our
stock price to decline include the demand for and acceptance of our products,
product enhancements and services, and our ability to attract new customers, as
well as a number of other factors described elsewhere in this "Risk Factors"
section.

OUR QUARTERLY OPERATING RESULTS ARE LIKELY TO FLUCTUATE SIGNIFICANTLY AND MAY
FAIL TO MEET THE EXPECTATIONS OF SECURITIES ANALYSTS AND INVESTORS, CAUSING OUR
SHARE PRICE TO DECLINE

     Our quarterly operating results have fluctuated significantly in the past
and are likely to fluctuate in the future depending on a number of factors
described below and elsewhere in this "Risk Factors" section of the prospectus,
including:

     - any delay in the introduction of new applications, services and product
       offerings and enhancements of existing solutions;

     - the loss of a major customer;

     - reductions in the average selling prices of our applications, services
       and product offerings;

                                        6
<PAGE>   10

     - cost pressures from shortages of skilled technical employees, increased
       product development and engineering expenditures; and

     - changes in industry market conditions.

     Due to the factors described above and other factors, our results of
operations could fluctuate substantially in the future, and quarterly
comparisons may not indicate reliable trends of future performance. If our
operating results do not meet the expectations of securities analysts and
investors, our share price is likely to decline.

FAILURE TO DEVELOP AND MAINTAIN STRATEGIC RELATIONSHIPS WOULD DELAY THE GROWTH
OF OUR BUSINESS

     Strategic relationships, especially with our customers and vendors, are
critical to our success. Entering into strategic relationships is complicated
because it involves identifying opportunities and collaborating with a number of
our customers, vendors and competitors. In addition, we may not be able to
establish relationships with particular key participants in the health care
industry if we have established relationships with competitors. It is important
that we are perceived as independent of any particular customer or partner.
Moreover, many potential customers and vendors may resist working with us until
our applications, services and product offerings have been successfully
introduced and have achieved market acceptance.

     Once we have established strategic relationships, we will depend on our
customers' and vendors' ability to assist us in generating increased acceptance
and use of our solutions. To date, we have established only a limited number of
strategic relationships, and these relationships are in the early stages of
development. We have limited experience in establishing and maintaining
strategic relationships with health care industry participants. If we were to
lose any of these strategic relationships or fail to establish additional
relationships, or if our strategic customers and vendors fail to collaborate
with us to pursue additional business relationships and partnerships, we would
not be able to execute our business plans and our business would suffer
significantly. Moreover, we may not experience increased use of our
applications, services and product offerings even if we establish and maintain
these strategic relationships.

     Although we view our strategic relationships as a key factor in our overall
business strategy, our partners may not view their relationships with us as
significant to their own business, and they may reassess their commitment to us
or decide to compete directly with us in the future. We generally do not have
agreements that prohibit our strategic partners from competing against us
directly or from contracting with our competitors. We cannot guarantee that any
strategic partner will perform its obligations as agreed or contemplated or that
we would be able to specifically enforce any strategic agreement. Our
arrangements with our strategic partners generally do not establish minimum
performance requirements, but instead rely on the voluntary efforts of our
strategic partners. Therefore, we cannot guarantee that these relationships will
be successful.

     We also expect to compete with other companies, including those that have
greater financial resources than our company, for the right to enter into
strategic relationships. This competition for strategic relationships in the
health care electronic commerce industry could affect our ability to consummate
future relationships on acceptable terms, or at all. For additional information
regarding strategic relationships, see "Business -- Strategy" and "-- Strategic
Relationships."

THE HEALTH CARE INDUSTRY MAY NOT ACCEPT OUR SOLUTIONS

     To be successful and to grow, we must attract a significant number of
customers throughout the health care industry. To date, the health care industry
has been resistant to adopting new information technology solutions. Electronic
information exchange and transaction processing by the health care industry is
still developing. We believe that complexities in the nature of health care
transactions and lack of a common technology platform have hindered the
development and acceptance of information technology solutions by the industry.
There are currently hundreds of different incompatible hardware,

                                        7
<PAGE>   11

software and database components. Issues still remain as to integrating these
traditional systems with the real-time transactional capabilities of our
technologies. Even if this integration can be achieved as rapidly as we expect,
health care industry participants may use products and services offered by
others.

     Acceptance of Internet technology by physicians and other providers into
daily administrative and clinical workflow is a key factor in our ability to
meet our anticipated deployment levels for transaction services and process
automation components. We have taken the initial steps to meeting the challenge
of provider acceptance by deploying solutions that we believe lower their cost
of health care administration. In addition, our sales and marketing strategy
concentrates on targeting customers' back-office processing needs, bypassing the
provider as decision makers and focusing on a return-on-investment approach for
cost justification. However, without the acceptance by physicians and providers
of workflow modifications, new installation projects, such as our solutions, may
be stalled.

IF THE EXTENSIBLE MARKUP LANGUAGE FAILS TO BECOME A STANDARD DATA EXCHANGE
PROTOCOL FOR THE INTERNET, THE MARKETABILITY OF OUR PRODUCTS MAY BE LIMITED

     Our XCare.net platform operates with the extensible markup language, or
XML. We expect XML to be a predominant protocol for exchanging data for
electronic commerce on the Internet in the future. The failure of XML to become
well-accepted would seriously impede the marketability of our products and force
us to adapt our products to other data exchange protocols. Any such adjustments
may entail substantial costs, may require substantial time and effort, and may
not necessarily lead to marketable and competitive products. In addition, if
incompatible versions of the XML standard are developed, the market for
XML-based applications may fail to grow or grow more slowly than we anticipate.
If we develop our applications, services and product offerings based on a
version of XML that does not gain widespread acceptance, we may have to adapt
our products to another version of XML, which would cause delays in shipments of
our application and product offerings and impede our ability to provide
services.

OUR REVENUE IS CONCENTRATED IN A FEW CUSTOMERS, WHICH PUTS OUR REVENUE AT RISK

     We receive a substantial majority of our revenue from a limited number of
customers. In 1998, sales to Employers Mutual, Inc. accounted for 29% of
revenue, sales to Brokerage Services, Inc. accounted for 20% of revenue, sales
to Quest Diagnostics Incorporated accounted for 12% of revenue and sales to ADIS
International accounted for 11% of revenue. For the six months ended June 30,
1999, sales to American Medical Pathways, Inc. a subsidiary of American Medical
Response, Inc., accounted for 26% of revenue, sales to Methodist Care, Inc.
accounted for 24% of revenue, sales to Quest Diagnostics Incorporated accounted
for 20% of revenue and sales to Brokerage Services Incorporated accounted for
11% of revenue. We expect that a significant portion of our revenue will
continue to depend on sales to a small number of customers. If we do not
generate as much revenue from these major customers as we expect to, or if we
lose any of them as customers, our total revenue will be significantly reduced.

     We have a contract with American Medical Pathways, Inc., a wholly owned
subsidiary of American Medical Response, Inc., to provide third-party
administrative services in connection with its contracts to provide medical
transportation services. Our revenue under this contract accounted for 26% of
our revenue during the six month period ended June 30, 1999. American Medical
Pathways, Inc. may terminate our contract on 120 days notice. In addition,
Laidlaw, Inc., the owner of American Medical Response, Inc., recently announced
its decision to seek a buyer for American Medical Response, Inc. A new owner of
American Medical Response, Inc. may not continue to provide the same level of
medical transportation services or may seek to terminate our contract. Any
termination of the contract or reduction in license fees earned under the
contract would reduce our revenue and could slow our growth. American Medical
Response, Inc. is the largest provider of private ambulance service in the
United States. Therefore, if we lose revenue due to termination of the contract
or reduction in license fees, it will be difficult to replace such revenue
through contracts with other providers of medical transportation services.
                                        8
<PAGE>   12

IF WE LOSE KEY LICENSES WE MAY BE REQUIRED TO DEVELOP OR LICENSE ALTERNATIVE
TECHNOLOGY, WHICH MAY CAUSE DELAYS, ADD CONSIDERABLE EXPENSE OR REDUCE SALES

     We currently rely on software that we have licensed from Sinclair Montrose
Healthcare plc of London, England for our Match.Net Staffing and Scheduling. We
will integrate this software with our software applications, services and
product offerings to centralize the scheduling and staffing functions for health
care providers in a secure Internet environment. We currently have an exclusive
license to the software, although exclusivity may terminate if we are unable to
meet milestones. This license may not continue to be available to us on
commercially reasonable terms in the future. The loss of this license could
result in delays or reductions of shipments of our MatchNet Staffing &
Scheduling product until equivalent software could be identified, developed,
licensed and integrated. In addition, other products and services we may offer
in the future may rely on licensed software. The loss of any current or future
license could result in delays in the introduction of our products and services,
add additional expense, and reduce sales of our products and services until
equivalent software could be developed, identified, licensed and integrated.

WE FACE SECURITY AND NETWORK RISKS THAT COULD RESULT IN LIABILITY TO US OR COULD
DAMAGE OUR REPUTATION

     We currently process substantially all of our customer transactions and
data at our facility in Albuquerque, New Mexico. Although we have safeguards for
emergencies, we do not have back-up facilities to process information if this
facility is not functioning. The occurrence of a major catastrophic event or
other system failure at our Albuquerque, New Mexico facility could interrupt
data processing or result in the loss of stored data. In addition, we depend on
the efficient operation of Internet connections from customers to our systems.
These connections, in turn, depend on the efficient operation of Web browsers,
Internet service providers and Internet backbone service providers, all of which
have had periodic operational problems or experienced outages. Any system
delays, failures or loss of data, whatever the cause, could reduce customer
satisfaction with our applications, services and product offerings.

     We retain confidential customer and patient information in our processing
centers. Therefore, it is critical that our facilities and infrastructure remain
secure and that our facilities and infrastructure are perceived by the
marketplace to be secure. Despite the implementation of security measures, our
infrastructure may be vulnerable to physical break-ins, computer viruses,
programming errors, attacks by third parties or similar disruptive problems. If
we fail to meet our clients' expectations, we could be liable for damages and
our reputation could suffer. In addition, patient care could suffer and we could
be liable if our systems fail to deliver correct information in a timely manner.
Our insurance may not protect us from this risk.

     Our customers have in the past experienced some interruptions with our
transaction hosting services. We believe that these interruptions will continue
to occur from time to time. These interruptions could be due to hardware and
operating system failures. We expect a large portion of our revenue to be
derived from customers who use our transaction hosting services. As a result,
our business will suffer if we experience frequent or long system interruptions
that result in the unavailability or reduced performance of our hosting. We
expect to experience occasional temporary capacity constraints due to sharply
increased traffic, which may cause unanticipated system disruptions, slower
response times, impaired quality and degradation in levels of customer service.
If this were to continue to happen, our business and reputation could be
seriously harmed.

OUR MARKETS ARE HIGHLY COMPETITIVE AND COMPETITION COULD HARM OUR ABILITY TO
SELL APPLICATIONS, SERVICES AND PRODUCT OFFERINGS

     Competition could seriously harm our ability to sell additional products
and services. The emerging Internet-based health care market is undergoing rapid
technological change. The ubiquitous reach of the Internet, coupled with the
availability and acceptability of new Internet-based technologies, has created
                                        9
<PAGE>   13

significant opportunities in health care for both legacy and new Internet-based
system vendors. Potential competitors fall into three primary categories: health
care Internet companies focused on providing connectivity and transactions
within business-to-business and business-to-consumer frameworks; traditional
health care information system vendors who seek to extend the services of their
core products using Internet-based technology; and traditional managed care
information system and outsourcing vendors who generally sell legacy systems and
are focusing on extending the services of their core products to the Internet.
In addition, from time to time our customers may develop applications, services
and product offerings competitive with those offered by us.

     Many of our competitors have longer operating histories, significantly
greater financial, technical, marketing or other resources, or greater name
recognition than we do. Our competitors may be able to respond more quickly than
we can to new or emerging technologies and changes in customer requirements. Our
competitors may develop and successfully market Internet-based health care
products and services in a manner that could have an adverse effect on our
business model. See "Business -- Competition."

WE NEED TO EXPAND OUR MANAGEMENT SYSTEMS AND NETWORK INFRASTRUCTURE TO SUPPORT
GROWTH

     In order to grow, we intend to rapidly expand our management, product
development, testing, network operations, marketing, sales and customer service
personnel over the next year. This growth has and will continue to place a
significant strain on our managerial, operational, financial and information
systems resources. We may not be able to effectively manage expansion of our
operations, and our facilities, systems, procedures or controls may not be
adequate to support our operations. Moreover, our systems may not accommodate
increased use while maintaining acceptable overall performance.

     As we grow, we will also need to expand and adapt our network
infrastructure to accommodate additional users, increased transaction volumes
and changing customer requirements. So far, we have processed a limited number
and variety of transactions over our network infrastructure and only a limited
number of health care participants use our infrastructure. Many of our service
agreements contain performance standards. If we fail to meet these standards,
our customers could terminate their agreements with us. The loss of any of our
service agreements would cause a decline in our revenues. We may be unable to
expand or adapt our network infrastructure to meet additional demand or our
customers' changing needs on a timely basis and at a commercially reasonable
cost, or at all.

OUR OPERATING RESULTS MAY VARY SIGNIFICANTLY DUE TO THE LENGTHY SALES AND
IMPLEMENTATION CYCLES FOR OUR PRODUCTS AND SERVICES

     Because our applications, services and product offerings have lengthy sales
and implementation cycles, it is difficult for us to forecast the timing and
recognition of revenues from sales of our solutions. Since we are unable to
control many of the factors that will influence our customers' buying decisions,
the lengthy sales cycle could cause our operating results to be below the
expectations of analysts and investors.

     A key element of our strategy is to market our solutions to large
organizations with significant data management and access needs. The sales
process normally involves a significant evaluation process, and commitment of
budgets may be subject to delays due to a customer's internal procedures for
approving new expenditures and deploying new technologies. The period of time
between initial customer contact and a purchase order can span up to three
months or more.

     In addition, we often must provide a significant level of education to our
prospective customers regarding the use and benefit of our applications,
services and product offerings, which may cause additional delays during the
evaluation and acceptance process. General concerns regarding year 2000
compliance may further delay purchasing decisions by prospective customers. Our
long and unpredictable sales cycle can result in delayed revenues, difficulty in
matching revenues with expenses and increased expenditures, which together may
contribute to fluctuations in our results of operations and share price.
                                       10
<PAGE>   14

WE MAY LOSE EXISTING CUSTOMERS OR BE UNABLE TO ATTRACT NEW CUSTOMERS IF WE DO
NOT DEVELOP NEW APPLICATIONS, SERVICES AND PRODUCTS OR IF THESE SOLUTIONS DO NOT
KEEP PACE WITH TECHNOLOGICAL CHANGES

     Internet technologies are evolving rapidly and the technology used by any
electronic commerce business is subject to rapid change and obsolescence. If we
are not able to maintain and improve our products and develop new products that
keep pace with competitive product introductions and technological developments,
satisfy diverse and evolving customer requirements and achieve market
acceptance, we may lose existing customers or be unable to attract new
customers. For example, we currently are developing Physician Credentialing,
Electronic Medical Record, Case Management, Medication and Medical Assessment
Inquiry Systems, Physician Practice Management, MD Pay Accelerator, Online Drug
Store, Medical Supply Product, Health and Medical Bookstore products. We may not
be successful in developing and marketing these or other product enhancements or
new products that respond to technological advances by others on a timely or
cost-effective basis. In addition, such solutions may contain licensed
components which may be difficult to integrate or may cause the solutions to be
ineffective. These products, if developed, may not achieve market acceptance.
Any delay or problems in the installation or implementation of new products or
services may cause customers to forego purchases from us and could cause them to
purchase from our competitors.

IF WE ARE REQUIRED TO COMMIT UNANTICIPATED RESOURCES TO COMPLETE FIXED-PRICE
CONTRACTS, OUR OPERATING RESULTS MAY DECLINE

     We had historically derived a majority of our revenue from contracts that
were billed on a time-and-materials basis. Beginning in 1998, a significant
portion of our revenue has been derived from contracts that were billed on a
fixed-price basis. These contracts specify certain obligations and deliverables
to be met by us regardless of our actual costs incurred. We cannot assure you
that we can successfully complete these contracts on budget, and our inability
to do so could seriously harm our business, financial condition and results of
operations.

     Our failure to accurately estimate the resources required for a fixed-price
contract could cause our operating results to decline. In the past, we have been
required to commit unanticipated additional resources to complete certain
project plans during the project to ensure that the project was completed on
schedule. We may experience similar situations in the future.

GOVERNMENT REGULATION OF HEALTH CARE MAY IMPACT OUR BUSINESS

     Our business may be affected by current government regulations as well as
future regulations. Participants in the health care industry are subject to
extensive and frequently changing regulation under numerous laws administered by
governmental entities at the federal, state and local levels. Many current laws
and regulations, when enacted, did not anticipate the methods of Internet-based,
business-to-business, health care connectivity, information exchange and
electronic commerce that we are developing. We believe, however, that these laws
and regulations may be applicable to our business. Furthermore, the impact of
regulatory developments in the health care industry is complex and difficult to
predict, and we cannot guarantee that we will not be seriously harmed by
existing or new regulatory requirements or interpretations.

     Furthermore, our health care service provider, payer and plan customers are
also subject to a wide variety of laws and regulations that could affect the
nature and scope of their relationships with us. Laws regulating health
insurance, health maintenance organizations and similar organizations, as well
as employee benefit plans, cover a broad array of subjects, including
confidentiality, financial relationships with suppliers, mandated benefits and
grievance and appeal procedures. Laws governing health care providers, payers
and plans are often not uniform between states, and could require us to
undertake the

                                       11
<PAGE>   15

expense and difficulty of tailoring our business procedures, information
systems, or financial relationships in order for our customers to be in
compliance with applicable laws and regulations. Compliance with such laws could
also interfere with the scope of our applications, services and product
offerings, or make them less cost-effective for our customers.

     Current laws and regulations which may affect our health care business
include:

     - the Health Insurance Portability and Accountability Act of 1996, which
       mandates the use of standard transactions, standard identifiers, security
       and other provisions by the year 2000;

     - the regulation of confidential patient medical record information;

     - laws relating to the licensing and regulation of third-party
       administrators, private review agents, utilization review agents and
       others providing administrative services to health plans and health care
       providers;

     - laws relating to the billing, collection and reimbursement of health care
       services;

     - laws relating to the practice of medicine and other healing arts
       professions;

     - laws relating to the relationships between or among health care providers
       and health care providers and third parties;

     - laws governing the prescribing, including electronic transmission of
       prescriptions, dispensing and delivery of prescription drugs; and

     - laws relating to the advertising and sale of health care products.

     Additional government regulation and health care reform laws and
regulations may be adopted with respect to the Internet or other online services
covering issues such as user privacy, pricing, content, copyrights,
distribution, and the characteristics and quality of products and services. The
adoption of any new laws or regulations may impede the growth of the Internet or
other online services. This could, in turn, decrease the demand for our
applications, services and product offerings and increase our cost of doing
business. Moreover, the applicability to the Internet of existing laws in
various jurisdictions governing issues such as property ownership, sales and
other taxes, libel and personal privacy is uncertain and may take years to
resolve. Any such new legislation or regulation, the application of laws and
regulations from jurisdictions whose laws do not currently apply to our
business, or the application of existing laws and regulations to the Internet
and other online services could limit our growth and cause a substantial
compliance burden. We expect to conduct our business in substantial compliance
with all material federal, state and local laws and regulations governing our
operations.

     Some computer applications and software are considered medical devices and
are subject to regulation by the United States Food and Drug Administration, or
FDA, although the FDA could take a contrary view. In addition, we do not believe
that our current applications, services or product offering are subject to FDA
regulation. We may expand our applications, services and product offerings into
areas subject to FDA regulation. We have no experience in complying with FDA
regulations. We believe that complying with FDA regulations would be time
consuming, burdensome and expensive and could delay our introduction of new
solutions. For more information on government regulation affecting our business,
see "Business -- Government Regulation."

WE MAY INCUR LIABILITY AS A RESULT OF PROVIDING UTILIZATION REVIEW SERVICES

     One of the functions of our applications is automatic adjudication of
whether or not a claim for payment or service should be denied or whether
existing coverage should be continued based upon particular plans or contracts
and industry-standard, clinical-support criteria. Our payer customers are
ultimately responsible for deciding whether to deny claims for payment or
medical services. It is possible, however, that liability may be asserted
against us for denial of payment of medical claims or medical service. The
contractual protections included in our customer contracts and our insurance
coverage may not be sufficient to protect us against such liability.

                                       12
<PAGE>   16

OUR EXECUTIVE OFFICERS AND KEY PERSONNEL ARE CRITICAL TO OUR BUSINESS AND THESE
OFFICERS AND KEY PERSONNEL MAY NOT REMAIN WITH US IN THE FUTURE

     Our future success depends upon the continued service of our executive
officers and other key employees as well as our ability to hire a significant
number of new employees. In particular, it would be difficult for us to replace
the services of our President and Chief Executive Officer, Lorine Sweeney. In
addition, we are particularly dependent on the continued services of software
developers with programming skills in XML, Java and Oracle. Competition for
these individuals is intense, and we may not be able to attract, assimilate or
retain additional highly qualified personnel in the future. None of our
executive officers or key personnel have employment agreements with us, except
for standard agreements we have with all of our employees providing for
confidentiality and invention assignment obligations. We plan to obtain
"key-person" life insurance policies covering key executive officers.

WE MAY FACE PRODUCT-RELATED LIABILITIES THAT COULD FORCE US TO PAY DAMAGES WHICH
WOULD HURT OUR REPUTATION

     While we and our customers test our applications, services and product
offerings, they may contain defects or result in system failures. These defects
or problems could result in the loss of or delay in generating revenue, loss of
market share, failure to achieve market acceptance, diversion of development
resources, injury to our reputation or increased insurance costs.

     Our contracts limit our liability arising from our errors; however, these
provisions may not be enforceable and may not protect us from liability. While
we have general liability insurance that we believe is adequate, including
coverage for errors and omissions, we may not be able to maintain this insurance
on reasonable terms in the future. In addition, our insurance may not be
sufficient to cover large claims and our insurer could disclaim coverage on
claims. If we are liable for an uninsured or underinsured claim or if our
premiums increase significantly, our financial condition could be materially
harmed.

IF WE DO NOT ESTABLISH AND MAINTAIN THE XCARE.NET BRAND, OUR REPUTATION COULD BE
ADVERSELY AFFECTED

     In order to increase our customer base and expand our online traffic, we
must establish, maintain and strengthen the XCare.net brand. For us to be
successful in establishing our brand, health care professionals must perceive us
as offering quality, cost-effective, communications, information and
administrative services. Our reputation and brand name could be adversely
affected if we experience difficulties in introducing new applications, services
and product offerings, if these applications, services and product offerings are
not accepted by customers, if we are required to discontinue existing
applications, services and product offerings or if our products and services do
not function properly.

OUR GROWTH AND OPERATING RESULTS WOULD BE IMPAIRED IF WE WERE UNABLE TO MEET OUR
FUTURE CAPITAL REQUIREMENTS

     We expect that the money generated from this offering, combined with our
current cash resources, will be sufficient to meet our requirements for
approximately 12 months. However, we expect that we will continue to experience
negative cash flow in the near term. Accordingly, we may need to raise
additional capital to support expansion, develop new or enhanced applications,
services and product offerings, respond to competitive pressures, acquire
complementary businesses or technologies or take advantage of unanticipated
opportunities. We may need to raise additional funds by selling debt or equity
securities, by entering into strategic relationships or through other
arrangements. We cannot assure you that we will be able to raise any additional
amounts on reasonable terms, or at all, when they are needed.

                                       13

ACQUISITIONS COULD BE DIFFICULT TO INTEGRATE, DISRUPT OUR BUSINESS AND DILUTE
STOCKHOLDER VALUE

     We expect to acquire technologies and other health care technology
companies to increase the number and variety of applications, services and
product offerings we offer and to increase our customer base. To be successful,
we will need to identify applications, technologies and businesses that are
complementary to ours, integrate disparate technologies and corporate cultures
and manage a geographically dispersed company. Acquisitions could divert our
attention from other business concerns and expose us to unforeseen liabilities
or risks associated with entering new markets. Finally, we may lose key
employees while integrating these new companies. Integrating newly acquired
organizations and technologies into XCare.net could be expensive, time consuming
and may strain our resources. In addition, we may lose our current customers if
any acquired companies have relationships with competitors of our customers.
Consequently, we may not be successful in integrating any acquired businesses or
technologies and may not achieve anticipated revenue and cost benefits. The
health care industry is consolidating and we expect that we will face
intensified competition for acquisitions, especially from larger, better-funded
organizations. If we fail to execute our acquisition strategy successfully for
any reason, our business will suffer significantly.

     We intend to pay for some of our acquisitions by issuing additional common
stock and this could dilute our stockholders. We may also use cash to buy
companies or technologies in the future. If we do use cash, we may need to incur
debt to pay for these acquisitions. Acquisition financing may not be available
on favorable terms or at all. In addition, we may be required to amortize
significant amounts of goodwill and other intangible assets in connection with
future acquisitions, which would seriously harm our results of operations.

OUR PROPRIETARY TECHNOLOGY MAY BE SUBJECTED TO INFRINGEMENT CLAIMS OR MAY BE
INFRINGED UPON

     Our intellectual property is important to our business. We expect that we
could be subject to intellectual property infringement claims as the number of
our competitors grows and the functionality of our applications overlap with
competitive offerings. These claims, whether or not meritorious, could be
expensive and divert our attention from operating our company. If we become
liable to third parties for infringing their intellectual property rights, we
would be required to pay a substantial damage award and to develop noninfringing
technology, obtain a license or cease selling the applications that contain the
infringing intellectual property. We may be unable to develop noninfringing
technology or obtain a license on commercially reasonable terms, or at all. In
addition, we may not be able to protect against misappropriation of our
intellectual property. Third parties may infringe upon our intellectual property
rights, we may not detect this unauthorized use and we may be unable to enforce
our rights. See "Business -- Intellectual Property."

WE MAY NOT BE ABLE TO PROTECT AND ENFORCE OUR TRADENAMES, INTERNET ADDRESS AND
INTELLECTUAL PROPERTY RIGHTS.

     We seek to protect our brand and our other intellectual property through a
combination of copyright, trade secret and trademark laws. Our XCare.net brand
and our Internet address, www.xcare.net are important components of our business
strategy. We have recently filed federal trademark applications for "XCare.net,"
"XCare," "Solution Channels" and "the Business to Business Platform for
eHealth." We cannot guarantee that any of these trademark applications will be
granted. If we are unable to secure registration of these marks or otherwise
obtain the right to use these marks under contract or common law, we may be
required to stop using these marks. This could cause confusion to our customers
and in the marketplace and harm our business, financial condition and results of
operations.

     In addition, our future success and ability to compete in our markets may
be dependent in part on our proprietary rights to products and services which we
develop. We rely on copyright, trademark and

                                       14
<PAGE>   18

trade secret laws and contractual restrictions. We also expect to rely on
patents to protect our proprietary technology and to rely on similar proprietary
rights of any of our technology providers. We intend to file patent applications
to protect certain of our proprietary technology. We cannot assure you that such
applications will be approved or, if approved, will be effective in protecting
our proprietary technology. We enter into confidentiality agreements with all of
our employees, as well as with our customers and potential customers seeking
proprietary information, and limit access to and distribution of our software,
documentation and other proprietary information. We cannot assure you that the
steps we take or the steps such providers take would be adequate to prevent
misappropriation of our respective proprietary rights.

POTENTIAL YEAR 2000 PROBLEMS WITH OUR PRODUCTS OR INTERNAL SYSTEMS MAY INVOLVE
SIGNIFICANT TIME AND EXPENSE AND MAY REDUCE OUR FUTURE SALES

     Many currently installed computer systems and software products store dates
using only the last two digits of the calendar year. As a result, such systems
may not be able to distinguish whether "00" means 1900 or 2000, which may cause
system failures or erroneous results. Year 2000 problems could subject us to
liability claims and disrupt our customers' purchasing patterns, either of which
could harm our business.

     Our applications, services and product offerings operate in complex network
environments and directly or indirectly interact with a number of other hardware
and software systems that we cannot adequately evaluate for year 2000
compliance. We may face claims based on year 2000 problems in other companies'
products, or issues arising from the integration of multiple products within an
overall system. Although we have not been a party to any litigation or
arbitration proceeding involving our solutions related to year 2000 compliance
issues, we may in the future be required to defend our applications, services
and product offerings in such proceedings, or to negotiate resolutions of claims
based on year 2000 issues. Defending and resolving year 2000-related disputes,
regardless of the merits of such disputes, and any liability we have for year
2000-related damages, including consequential damages, could be expensive to us.
In addition, we believe that customers and potential customers limit purchases
of new applications, services and product offerings due to year 2000 issues as
companies expend significant resources to correct or upgrade their current
software systems for year 2000 compliance. These expenditures may result in
reduced funds available to purchase our applications, services and product
offerings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."

GOVERNMENT REGULATION OF INTERNET COMMUNICATIONS MAY IMPACT OUR BUSINESS BY
DIRECTLY OR INDIRECTLY INCREASING OUR COSTS

     We provide Internet services, in part, through data transmissions over
public telephone lines. These transmissions are governed by regulatory policies
establishing charges and terms for wireline communications. We currently are not
subject to direct regulation by the Federal Communications Commission or any
other governmental agency, other than regulations applicable to businesses
generally.

     However, in the future we could become subject to regulation by the Federal
Communications Commission or another regulatory agency as a provider of basic
telecommunications services. Changes in the regulatory environment relating to
the application of access charges and Universal Service Fund support payments to
Internet and Internet telephony providers, regulation of Internet services,
including Internet telephony, and other regulatory changes that directly or
indirectly affect costs imposed on Internet or Internet telephony providers,
telecommunications costs or increase in the likelihood or scope of competition,
could harm our business and financial results.

                                       15
<PAGE>   19

OUR OFFICERS, DIRECTORS AND AFFILIATED ENTITIES WILL HAVE SIGNIFICANT CONTROL
OVER US AND MAY APPROVE OR REJECT MATTERS CONTRARY TO OUR STOCKHOLDERS' VOTE

     Our executive officers and directors, together with their affiliates, will
beneficially own an aggregate of approximately      % of our outstanding common
stock following the completion of the offering. These stockholders, if acting
together, will be able to significantly influence all matters requiring approval
by our stockholders, including the election of directors and the approval of
mergers or similar transactions even if other stockholders disagree. See
"Principal Stockholders."

WE HAVE ANTI-TAKEOVER DEFENSES THAT COULD DELAY OR PREVENT AN ACQUISITION OF OUR
COMPANY

     Provisions of our certificate of incorporation, bylaws, other agreements
and Delaware law could make it more difficult for a third-party to acquire us,
even if doing so would be beneficial to our stockholders. See "Description of
Capital Stock."

WE HAVE BROAD DISCRETION TO USE THE OFFERING PROCEEDS AND OUR INVESTMENT OF
THESE PROCEEDS MAY NOT YIELD A FAVORABLE RETURN

     We intend to use the proceeds from the offering for general corporate
purposes, including working capital, capital expenditures and repayment of
long-term indebtedness, and may use a portion of proceeds to acquire other
businesses, products or technologies. Our management will have considerable
discretion in the application of the net proceeds of this offering, and you will
not have the opportunity, as part of your investment decision, to assess whether
the proceeds are being used appropriately. The net proceeds of this offering may
be used for corporate purposes that do not increase our results of operations or
our market value. Pending any such uses, we plan to invest the net proceeds of
the offering in investment-grade, interest-bearing securities. We cannot predict
that such investments will yield a favorable return. See "Use of Proceeds."

OUR SECURITIES HAVE NO PRIOR MARKET AND WE CANNOT ASSURE YOU THAT OUR STOCK
PRICE WILL NOT DECLINE AFTER THE OFFERING

     Our common stock has never been sold in a public market. An active trading
market for our common stock may not develop or be sustained after completion of
the offering. The initial public offering price may not be indicative of the
prices that will prevail in the public market after the offering, and the market
price of the common stock could fall below the initial public offering price. In
addition, the stock market has experienced extreme price and volume
fluctuations, which have particularly affected the market prices of many
technology companies and which have often been unrelated to the operating
performance of such companies. See "Underwriting."

WE MAY BE SUBJECT TO LITIGATION IF OUR COMMON STOCK PRICE IS VOLATILE

     In the past, following periods of volatility in the market price of a
company's securities, securities class action litigation has often been
instituted against the company. The institution of class action litigation
against us could result in substantial costs to us and a diversion of our
management's attention and resources which would harm our business, financial
condition and results of operations. Any adverse determination in this
litigation could also subject us to significant liabilities.

SHARES ELIGIBLE FOR FUTURE SALE AFTER THE OFFERING COULD CAUSE OUR STOCK PRICE
TO FALL

     If our stockholders sell substantial amounts of our common stock in the
public market following the offering, the market price of our common stock could
fall. Such sales also might make it more difficult for XCare.net to sell equity
or equity-related securities in the future at a time and price that we deem
appropriate. Based upon the number of our shares outstanding as of September 30,
1999, upon completion of the offering, we will have outstanding      shares of
common stock, assuming no

                                       16
<PAGE>   20

exercise of the underwriters' option to purchase additional shares and no
exercise of outstanding options after September 30, 1999. Of these shares, the
shares sold in the offering will be freely tradable.      shares of common stock
will be available for sale in the public 180 days after the date of this
prospectus or afterwards.

     Based on the number of our shares outstanding as of September 30, 1999,
after the offering, the holders of approximately 97,987,462 shares of common
stock, which represent      % of our outstanding stock after completion of the
offering, will be entitled to certain rights to have the resale of their shares
registered under the Securities Act of 1933. If these holders, by exercising
their registration rights, cause a large number of securities to be registered
and sold in the public market, such sales could materially and adversely affect
the market price for our common stock. In addition, if we were to include in a
registration statement shares held by these holders pursuant to the exercise of
their registration rights, such sales may impede our ability to raise needed
capital. See "Shares Eligible for Future Sale" and "Underwriting."

WE DO NOT INTEND TO PAY DIVIDENDS, AND YOU MAY NOT EXPERIENCE A RETURN ON
INVESTMENT WITHOUT SELLING SHARES

     Except for dividends declared in connection with our status as an S
corporation prior to January 1996, we have not declared or paid any cash
dividends on our capital stock. You will not experience a return on your
investment in our common stock without selling your shares because we currently
intend on retaining future earnings to fund our growth and do not expect to pay
dividends in the foreseeable future. See "Dividend Policy."

NEW INVESTORS IN OUR COMMON STOCK WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL
DILUTION

     If you purchase shares of our common stock, you will incur immediate and
substantial dilution in pro forma net tangible book value. Investors
participating in the offering of our common stock will pay a price per share,
which substantially exceeds the value of our assets after subtracting our
liabilities. These investors will contribute      % of the total amount paid to
fund us but will own only      % of our outstanding shares. If the holders of
outstanding options or warrants exercise those options or warrants, you will
suffer further dilution. See "Dilution."

YOU SHOULD NOT RELY ON FORWARD-LOOKING STATEMENTS BECAUSE THEY ARE INHERENTLY
UNCERTAIN

     This prospectus contains forward-looking statements that relate to future
events or our future financial performance, which involve risks and
uncertainties. We use words such as "anticipates," "believes," "plans,"
"expects," "future," "intends" and similar expressions to identify such forward-
looking statements. You should not place undue reliance on these forward-looking
statements, which apply only as of the date of this prospectus. These statements
are only predictions. Our actual results could differ materially from those
anticipated in these forward-looking statements for many reasons, including the
risks faced by us described throughout this "Risk Factors" section and elsewhere
in this prospectus.

                                USE OF PROCEEDS

     The net proceeds to us from the sale of shares of our common stock in the
offering at an estimated initial public offering price of $          per share,
after deducting estimated expenses of $          and underwriting discounts and
commissions, are estimated to be approximately $          (approximately
$          if the underwriters' over-allotment option is exercised in full).

     We expect to use the net proceeds from this offering for general corporate
purposes, working capital and capital expenditures to fund our operations,
including to continue expanding and enhancing our sales and marketing operations
and to continue expanding our product offerings. We have not yet determined our
expected use of these proceeds, but we currently anticipate that we will incur
approximately $3 million in research and development expenses, $7 million in
sales and marketing expenses, $1 million in hardware and software purchases and
$6 million in general and administrative expenses over the next 12 months.
Actual expenditures may vary substantially from these estimates. The amounts and
timing of our actual expenditures will depend upon numerous factors, including
the status of our product development efforts, marketing and sales activities,
and the amount of cash generated by our operations and competition. We may find
it necessary or advisable to use portions of the proceeds for other purposes.

     A portion of the proceeds may also be used to acquire or invest in
complementary businesses or products or to obtain the right to use complementary
technologies, although there are no current plans, negotiations or discussions
for any such transactions. Pending use of the net proceeds for the above
purposes, we intend to invest such funds in short-term, interest-bearing,
investment grade obligations.

                                DIVIDEND POLICY

     Except for dividends declared in connection with our status as an S
corporation prior to January 1996, we have never declared or paid any cash
dividends on our common stock or other securities. We currently anticipate that
we will retain all of our future earnings for use in the expansion and operation
of our business and do not anticipate paying any cash dividends in the
foreseeable future.

                                 CAPITALIZATION

     The following table sets forth our total capitalization as of June 30, 1999
on an actual, pro forma and pro forma as adjusted basis. The pro forma
capitalization reflects the automatic conversion of all outstanding shares of
our convertible preferred stock into common stock upon the closing of this
offering, the assumed cashless exercise of all outstanding common and
convertible preferred stock warrants with exercise prices below an assumed
initial public offering price, the conversion of the convertible preferred stock
issued upon the assumed exercise of the latter warrants into common stock, and
amendments to our certificate of incorporation effective after June 30, 1999.
The pro forma as adjusted capitalization reflects our receipt of estimated net
proceeds from the sale of the        shares of common stock in this offering (at
an estimated initial public offering price of $     per share and after
deducting estimated underwriting discounts and commissions and estimated
offering expenses):

                                    DILUTION

     Our pro forma net tangible book value as of June 30, 1999 was approximately
$5.0 million or $0.06 per share of common stock, after giving effect to the
conversion of our outstanding convertible preferred stock, the assumed cashless
exercise of all outstanding common and convertible preferred stock warrants with
exercise prices below an assumed initial public offering price, and the
conversion of the convertible preferred stock issued upon assumed exercise of
the warrants into common stock. Pro forma net tangible book value per share
represents total tangible assets less total liabilities, divided by the number
of outstanding shares of common stock after giving effect to the transactions
described in the previous sentence.

     Dilution in net tangible book value per share represents the difference
between the amount per share paid by purchasers of shares of our common stock in
this offering and the net tangible book value per share of our common stock
immediately afterwards. After giving effect to our sale of the      shares of
     common stock in this offering at an assumed initial public offering price
of $     per share, and after deducting estimated underwriting discounts and
commissions and estimated offering expenses, our pro forma net tangible book
value at June 30, 1999 would have been approximately $          or $     per
share. This represents an immediate increase in net tangible book value to
existing stockholders of $     per share and an immediate dilution to new public
investors of $     per share. The following table illustrates the per share
dilution:

     In reviewing the above data, you should consider the following:

     - During 1996, a major customer terminated its contract with us and paid
       $2.3 million to settle all claims arising from the termination. During
       1997, another major customer terminated its contract with us and paid
       $250,000 to settle all claims associated with the termination.

     - As a result of the contract terminations referred to above, during 1997
       we abandoned an operating lease and incurred impairment charges for
       related fixed assets aggregating $887,000.

     - Prior to January 1, 1996, XCare.net was an S corporation for federal and
       state income tax purposes, and, accordingly, our income was taxed
       directly to our stockholders. Pro forma income before income taxes and
       pro forma net income and pro forma net income (loss) per common share for
       the years ended December 31, 1994 and 1995 give effect to pro forma
       adjustments that reflect the federal and state income taxes that would
       have been recorded if XCare.net had been a C corporation prior to January
       1, 1996.

     - See note 1 of notes to the financial statements for a description of the
       method used to compute net income (loss) per share and pro forma net loss
       per common share for all periods presented.

OVERVIEW

     XCare.net, Inc. is a leading provider of Internet-based,
business-to-business connectivity, information exchange and electronic commerce
solutions for health care. We have developed an Internet-based information and
transaction technology platform, which we call the XCare.net platform. Using the
XCare.net platform, we connect health care participants together into a
community structure and deliver applications, services and electronic commerce
product offerings that are designed to improve process efficiencies, reduce
administrative costs and create new revenue opportunities for our customers.

     We commenced operations in March 1989, but we did not begin to focus on
Internet-based health care solutions until mid-1998. We have historically
derived a significant portion of our revenue from sales of mainframe and
client-server software for managed health care systems and from providing
services to health care organizations seeking to outsource administrative
functions. We intend to derive an increasing portion of our future revenue from
our Internet-based applications, services and product offerings. Due to our
limited operating history in the Internet-based health care market, it is
difficult for us to predict with any accuracy our future results of operations.
Accordingly, we believe that our historical financial results are not
necessarily indicative of our future financial performance.

     At the end of the first quarter of 1996, our largest customer at the time,
who accounted for approximately 67% of 1996 revenue, changed its information
technology strategy and terminated its contract with us. In June 1996, the
customer paid approximately $2.3 million to settle all claims arising under the
termination.

     In the first quarter of 1997, we obtained financing from new investors
through the issuance of Series A convertible preferred stock. This financing
enabled us to develop and pursue a new strategic plan to supplement our
mainframe-based business with client-server applications and services. In
pursuing this strategy, we increased our expenditures in marketing, research and
development, and general administration.

     At the beginning of the third quarter of 1997, our largest customer at the
time, who accounted for approximately 74% of 1997 revenue, decided to pursue an
alternative software approach and terminated its contract with us. In August
1997, the customer paid $250,000 to settle all claims arising under the
termination. In response, we reduced headcount and other expenditures during the
fourth quarter of 1997 and the first quarter of 1998.

     Also at the end of 1997 and during the first quarter of 1998, we obtained
additional financing through the issuance of convertible promissory notes. This
financing allowed us to continue to license and implement our client-server
based product to new customers and begin development of our Internet-based
applications and services. Notwithstanding this financing, we had limited
available working capital during the latter part of 1998 through the first part
of 1999, causing us to reduce our sales and marketing, research and development,
and general and administration expenditures from 1997 levels.

     At the end of 1998, we obtained additional financing from our existing
investors through the issuance of convertible promissory notes, and in June and
July 1999, we obtained financing through the

                                       23
<PAGE>   27

issuance of Series B convertible preferred stock. These financings have enabled
us to add personnel and other resources to facilitate the development and
marketing of the new Internet-based applications, services and product
offerings.

     For contracts entered into subsequent to January 1, 1998, we recognize
revenue in accordance with the provisions of Statement of Position 97-2,
"Software Revenue Recognition." We derive revenue from license fees and related
services under the terms of fixed price contracts. Maintenance revenue is
derived from agreements for supporting and providing periodic updates to
licensed software. Consulting revenue consists of revenue from consulting
services provided pursuant to time and materials contracts. Transaction
processing revenue is derived from outsourcing and transaction hosting services
and is recognized on a per-transaction basis as services are performed.

     License fees and related services revenue is generally recognized from
fixed price contracts using the percentage-of-completion method of accounting
where collectibility of fees is reasonably assured. Where collectibility of fees
is not reasonably assured, we defer revenue and related costs as deferred
contract costs and recognize revenue and cost of revenue as cash is collected.

     We may encounter budget and schedule overruns on fixed price contracts
caused by increased material, labor or overhead costs. Adjustments to cost
estimates are made in the periods in which the facts requiring such revisions
become known. Estimated losses, if any, are recorded in the period in which
current estimates of total contract revenue and contract costs indicate a loss.
We do not require collateral for our receivables and an allowance is maintained
for potential credit losses.

     Maintenance revenue is recorded as unearned revenue and is recognized
ratably over the service period, which is generally 12 months. When maintenance
is bundled with the original license fee arrangement, its fair value is deferred
and recognized during the period such services are provided.

     Revenue from consulting services provided pursuant to time-and-materials
contracts is recognized as the services are performed.

     For contracts entered into prior to January 1, 1998, we recognized revenue
in accordance with Statement of Position 91-1, "Software Revenue Recognition."
Our revenue recognition for such pre-1998 contracts was substantially the same
as that discussed above.

     For the six months ended June 30, 1999, sales to American Medical Pathways,
Inc. accounted for 26% of revenue, sales to Methodist Care, Inc. accounted for
24% of revenue, sales to Quest Diagnostics Incorporated accounted for 20% of
revenue and sales to Brokerage Services, Inc. accounted for 11% of revenue. If
we do not generate as much revenue from these major customers as we expect to,
or if we lose any of them as customers, our revenue will be significantly
reduced.

     We incurred net losses and losses from operations for the six months ended
June 30, 1999 and the years ended December 31, 1998 and 1997. As of June 30,
1999, we had an accumulated deficit of approximately $12.1 million. Since we
began developing and marketing our Internet-based health care applications,
services, and product offerings in early 1999, we have funded our business
primarily by borrowing funds and from the sale of convertible preferred stock,
not from cash generated by our business. We expect to continue to incur
significant sales and marketing, research and development and general and
administrative expenses. As a result, we will experience losses and negative
cash flows for the foreseeable future. Factors which may prevent us from
achieving or maintaining profitability and cause our stock price to decline
include the demand for and acceptance of our solutions, and our ability to
attract new customers, as well as a number of other factors described in the
"Risk Factors" section.

     Subsequent to June 30, 1999, in connection with stock options granted to
certain employees under the stock plan, we will record deferred stock
compensation representing the difference between the exercise price of the
options and the deemed fair value of our common stock at the date of grant. This
deferred stock compensation will be amortized to expense over the period during
which the options or

                                       24

common stock subject to repurchase vest, generally four years, using an
accelerated method as described in Financial Accounting Standards Board
Interpretation No. 28.

</TABLE>

SIX MONTHS ENDED JUNE 30, 1999 COMPARED TO SIX MONTHS ENDED JUNE 30, 1998

     Revenue. Revenue increased 77% to $1.8 million for the six months ended
June 30, 1999 from $1.0 million for the six months ended June 30, 1998. This
increase reflects growth in the number of licenses to new customers, larger
transaction size and new custom software development projects, partially offset
by decreased transaction processing revenue, as two mainframe and client-server
software customers ceased to outsource transition processing to us after they
completed implementation of our software.

     Cost of revenue. Cost of revenue includes personnel and related overhead
costs, payments to third party consultants who assist with providing
implementation and support services, facilities costs and equipment
depreciation. Cost of revenue increased 65% to $1.6 million for the six months
ended June 30, 1999 from $992,000 for the six months ended June 30, 1998. This
increase reflects the hiring of additional customer service personnel and third
party consultants to support and execute the current license implementation
contracts and custom development projects as well as the amortization of
purchased software. Cost of revenue as a percentage of revenue was relatively
consistent between the two six-month periods.

     Sales and marketing. Sales and marketing expenses consist of personnel and
related overhead costs, including commissions and travel expenses, field sales
office expenses, and advertising and promotion costs. Sales and marketing
expenses decreased 48% to $293,000 for the six months ended June 30, 1999 from
$566,000 for the six months ended June 30, 1998, representing 16% and 54% of
revenue, respectively. The decrease in sales and marketing expenses in absolute
dollars and as a percentage of revenue reflects a significant reduction in sales
force personnel and other promotional marketing activities as a result of the
limited working capital available during the six months ended June 30, 1999 as
compared to the six months ended June 30, 1998. The majority of sales and
marketing activities during the six months ended June 30, 1999 were performed by
our senior management.

                                       25
<PAGE>   29

Subsequent to June 30, 1999, we have been expanding our sales and marketing
organization using the proceeds from the issuance of the Series B convertible
preferred stock received in June and July 1999.

     General and administrative. General and administrative expenses include
personnel and related overhead costs for our executive, administrative, finance
and human resources functions, as well as legal and accounting fees. General and
administrative expenses decreased 59% to $426,000 for the six months ended June
30, 1999 from $1.0 million for the six months ended June 30, 1998, representing
23% and 100% of revenue, respectively. The decrease in general and
administrative expenses in absolute dollars and as a percentage of revenue
reflects a significant reduction in average headcount during the six months
ended June 30, 1999 as compared to the six months ended June 30, 1998 as a
result of the limited working capital available during the 1999 period.

     Research and development. Research and development expenses include
personnel and related overhead costs for product development, enhancements to
existing applications and services and quality assurance activities. Research
and development expenses decreased 71% to $161,000 for the six months ended June
30, 1999 from $546,000 for the six months ended June 30, 1998, representing 9%
and 52% of total revenue, respectively. The decrease in research and development
expenses in absolute dollars and as a percentage of revenue reflects significant
reduction in research and development personnel in the six months ended June 30,
1999 as compared to the six months ended June 30, 1998 as a result of the
limited working capital available during the 1999 period. During the six months
ended June 30, 1998, we maintained additional staffing and incurred related
costs in connection with our strategic commitment to the development of the
XCare.net platform.

     Interest income (expense), net. Interest income (expense), net includes
interest expense on our convertible promissory notes and capital lease
obligations partially offset by interest income on cash and cash equivalent
balances. Interest expense, net of interest income, increased 43% to $258,000
for the six months ended June 30, 1999 from $180,000 for the six months ended
June 30, 1998 due to the issuance of additional convertible promissory notes in
late 1998.

     Provision for (benefit from) income taxes. No provision for federal and
state income taxes has been recorded for the six months ended June 30, 1999 or
1998 as we have incurred net operating losses for each of these periods. We
believe that, based on the history of losses and other factors, the weight of
available evidence indicates that it is more likely than not that we will not be
able to realize our deferred tax assets, and thus a full valuation allowance has
been recorded against such assets as of June 30, 1999 and 1998.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

     Revenue. Revenue decreased 62% to $2.3 million for the year ended December
31, 1998 from $6.0 million for the year ended December 31, 1997. This decrease
reflects a significant reduction in consulting revenue due to the loss of a
major customer during July 1997 that accounted for approximately $4.4 million,
or 74%, of total 1997 revenue.

     Cost of revenue. Cost of revenue decreased 54% to $2.1 million for the year
ended December 31, 1998 from $4.6 million for the year ended December 31, 1997.
As a percentage of revenue, cost of revenue increased to 92% in 1998 from 77% in
1997. The decrease in absolute dollars reflects significant reductions in
employee headcount due to limited availability of working capital in 1998. The
increase in cost of revenue as a percentage of revenue reflects decreased
revenue associated with a major contract termination in 1997 which was not
completely offset by a decline in cost of revenue due to certain fixed
infrastructure costs which are included in cost of revenue.

     Sales and marketing. Sales and marketing expenses decreased 62% to $965,000
for the year ended December 31, 1998 from $2.5 million for the year ended
December 31, 1997, representing 43% and 42% of revenue, respectively. The
decrease in absolute dollars reflects reductions in sales and marketing
personnel and decreased travel and entertainment costs due to the loss of the
significant customer described above. In addition, we incurred higher costs for
marketing, consulting, advertising and

                                       26
<PAGE>   30

promotion and attendance at trade shows in 1997 as compared to 1998 in
connection with our new strategic focus on client-server applications and
services, including various marketing studies and analyst research projects on
the client-server market.

     General and administrative. General and administrative expenses decreased
10% to $2.2 million for the year ended December 31, 1998 from $2.4 million for
the year ended December 31, 1997, representing 97% and 41% of revenue,
respectively. The increase as a percentage of revenue is due to significantly
reduced revenue and losses on the disposal of fixed assets from facilities that
were abandoned in 1998. The decrease in absolute dollars reflects a significant
reduction in management personnel due to the loss of the significant customer
described above, which was partially offset by charges relating to the loss on
disposal of property and equipment referred to above.

     Research and development. Research and development expenses decreased 84%
to $670,000 for the year ended December 31, 1998 from $4.2 million for the year
ended December 31, 1997, representing 30% and 70% of revenue, respectively. The
decrease in absolute dollars reflects management's decision to reduce staff and
support costs, as a result of the significant decrease in revenue. In addition,
during 1997, we had focused on developing and maintaining two separate software
applications, one for the mainframe market and one for the client-server market,
while in 1998 we were developing only the client-server product.

     Interest income (expense), net. Interest income (expense), net,
significantly increased to $437,000 for the year ended December 31, 1998 from
$5,000 of interest income for the year ended December 31, 1997, as a result of
interest expense incurred on the December 1997 and April 1998 convertible
promissory notes.

     Provision for (benefit from) income taxes. No provision for federal and
state income taxes has been recorded for the year ended December 31, 1998, as we
incurred a net operating loss. We believe that based on the history of losses
and other factors, the weight of available evidence indicates that it is more
likely than not that we will not be able to realize our deferred tax assets, and
thus a full valuation allowance has been recorded as of December 31, 1998.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

     Revenue. Revenue decreased 38% to $6.0 million for the year ended December
31, 1997 from $9.7 million for the year ended December 31, 1996. This decrease
reflects a significant reduction in consulting revenue due to the loss of a
major customer, who accounted for approximately $6.5 million, or 67%, of 1996
revenue.

     Cost of revenue. Cost of revenue increased 22% to $4.6 million for the year
ended December 31, 1997 from $3.7 million for the year ended December 31, 1996.
As a percentage of revenue, cost of revenue increased to 77% in 1997 from 39% in
1996. This increase in absolute dollars and as a percentage of revenue is due to
an increase in average headcount and travel expenses during 1997 and the
decrease in revenue associated with a major contract termination during 1997. In
addition, the number of third party consultants hired during 1997 increased
prior to the contract termination.

     Sales and marketing. Sales and marketing expenses increased 85% to $2.5
million for the year ended December 31, 1997 from $1.4 million for the year
ended December 31, 1996, representing 42% and 14% of revenue, respectively.
After we received the proceeds from the issuance of convertible preferred stock
in the first quarter of 1997, we focused on increasing our marketing
expenditures in an attempt to bring in new customers. The increase in absolute
dollars and as a percentage of revenue reflects decreased revenue, increased
average sales and marketing headcount, increased advertising and promotional
activities, and increased travel expenses during 1997.

     General and administrative. General and administrative expenses increased
10% to $2.4 million for the year ended December 31, 1997 from $2.2 million for
the year ended December 31, 1996, representing 41% and 23% of revenue,
respectively. The increase in absolute dollars and as a percentage

                                       27
<PAGE>   31

of revenue reflects the decreased revenue during 1997 and increased average
headcount during 1997, as several executive level employees were hired and
relocated to Albuquerque, New Mexico after we received proceeds from the
issuance of convertible preferred stock in the first quarter of 1997.

     Research and development. Research and development expenses increased 32%
to $4.2 million for the year ended December 31, 1997 from $3.2 million for the
year ended December 31, 1996, representing 70% and 33% of revenue, respectively.
During 1997, we hired additional personnel to continue development of our
software applications after the issuance of convertible preferred stock in the
first quarter of 1997.

     Impairment of long-lived assets and abandonment of operating
lease. Impairment of long-lived assets and abandonment of operating lease
increased 100% to $887,000 for the year ended December 31, 1997 from $0 for the
year ended December 31, 1996. During 1997, due to the loss of our largest
customer, we abandoned an operating lease and incurred impairment charges for
related fixed assets aggregating $887,000.

     Settlement received from contract termination. During 1996, our largest
customer terminated its contract with us and paid $2.3 million to settle all
claims arising under the termination. During 1997, another major customer
terminated its contract with us and paid $250,000 to settle all claims
associated with the termination.

     Interest income (expense), net. Interest income (expense), net did not
change significantly in the year ended December 31, 1997 from the year ended
December 31, 1996.

     Provision for (benefit from) income taxes. The 1997 tax benefit was
primarily due to net operating losses generated in 1997 which were partially
realized through a carryback of the net operating loss against income taxes paid
in 1996. The 1996 tax expense was related to taxable income generated in 1996.

     The effective tax rate for 1997 was approximately 12.8% which was lower
than the Federal statutory rate primarily because of the effect of recording a
valuation allowance against all of our remaining deferred tax assets at December
31, 1997. The effective tax rate for 1996 was approximately 82.6% which was
higher than the Federal statutory rate primarily because of the effect of our
conversion to a taxable corporation on January 1, 1996.

QUARTERLY RESULTS OF OPERATIONS

     We have experienced quarterly fluctuations in our operating and financial
results due to the timing and relative size of new custom software development
projects, cancellations of contracts, and fluctuations in costs, including
personnel, equipment and facilities costs. We expect quarterly results to
fluctuate in the future due to the timing and introduction of new applications
and services and other market factors. See "Risk Factors."

     The following tables set forth unaudited statement of operations data for
each of the six quarters ended June 30, 1999, as well as the percentage of our
revenue represented by each line item. This information has been derived from
our unaudited financial statements. The unaudited financial statements have been
prepared on the same basis as the audited financial statements contained in this
prospectus and include all adjustments, consisting only of normal recurring
adjustments, that we consider necessary for a fair presentation of this
information. These unaudited quarterly results should be read in conjunction
with the financial statements and notes thereto appearing elsewhere in the
prospectus. Our

</TABLE>

     Revenue increased significantly during the quarter ended March 31, 1999 due
to the progress made in completing several custom software development projects.
Revenue for the quarter ended June 30, 1999 decreased relative to the prior
quarter as limited working capital available during the six months ended June
30, 1999 resulted in a reduction in our sales force personnel and other
promotional marketing activities, which impeded our ability to generate new
sales leads.

     Cost of revenue as a percentage of revenue has varied from quarter to
quarter due to fluctuations in quarterly revenue and changes in associated
personnel costs. During the quarter ended March 31, 1999, cost of revenue
decreased as a percentage of revenue due to increased revenue from the
completion of several custom software development projects during the quarter.
During the quarter ended June 30, 1999, the increase in cost of revenue as a
percentage of revenue reflects the decreased revenue recognized during the
quarter, the amortization of purchased software and the transfer of certain
personnel from research and development to custom software development projects.

     During the quarter ended December 31, 1998, general and administrative
expense increased in absolute dollars and as a percentage of revenue due to an
approximate $360,000 loss on disposal of fixed assets. During the quarter ended
March 31, 1999, sales and marketing and general administrative expense declined
in both dollars and as a percentage of revenue due to substantial reductions of
personnel costs.

     Research and development expenses sharply declined following the quarter
ended March 31, 1998 due to reduction of research and development personnel
caused by limited working capital.

LIQUIDITY AND CAPITAL RESOURCES

     We have historically financed our operations through a combination of cash
flow from operations, private sales of common and convertible preferred stock,
and issuances of convertible promissory notes.

     During March 1997, we completed a sale of Series A convertible preferred
stock for net proceeds of $6.6 million. From the period December 1997 through
December 1998, we issued $2.7 million of convertible promissory notes. During
June and July 1999, we completed a sale of Series B convertible preferred stock
with net proceeds totaling $13.8 million of which $7.3 million was received in
June 1999 and $6.5 million was received in July 1999.

     At June 30, 1999, our principal sources of liquidity included $4.7 million
in working capital with $697,000 in outstanding debt. Outstanding debt at June
30, 1999 consists primarily of capital leases and unsecured notes payable to
former employees. Capital leases are secured by the underlying equipment, bear
interest at rates ranging from 9.3% to 11.0% and have maturity dates through
2000. Certain equipment financing agreements recorded as capital lease
obligations are subject to restrictive covenants that require us to maintain
certain financial ratios. We were not in compliance with the covenants as of
December 31, 1998 and June 30, 1999 and obtained a waiver of compliance for all
covenants through September 30, 1999. The capital lease obligations under the
financing arrangements that included the restrictive covenants were paid off
during September 1999.

     Net cash used in operating activities was $793,000 in the six months ended
June 30, 1999, $2.2 million in 1998 and $6.6 million in 1997. Net cash provided
by operating activities was $2.8 million in 1996. Net cash used in operating
activities is primarily attributable to net losses.

     Net cash provided by investing activities was $7,000 in the six months
ended June 30, 1999 and $167,000 in 1998. Net cash used in investing activities
was $318,000 in 1997 and $330,000 in 1996. Investing activities consist
primarily of purchases of computer hardware and software, office furniture and
equipment, offset by proceeds from the sale of property and equipment.

     Net cash provided by financing activities was $7.1 million in the six
months ended June 30, 1999, $1.5 million in 1998, and $6.2 million in 1997 and
consists primarily of net proceeds from the issuance of convertible preferred
stock and convertible promissory notes. Net cash used in financing activities
was $1.3 million in 1996, which reflects principal payments on debt and cash
paid for the repurchase of common stock from former employees.

     We believe that the net proceeds from the offering, together with existing
sources of liquidity, will be sufficient to meet our working capital and
anticipated capital expenditure requirements for at least the next 12 months.
Thereafter, we may require additional funds to support our working capital
requirements or for other purposes, and we may seek, even before such time, to
raise additional funds through public or private equity financing or from other
sources. Such additional financing may not be available at all or, if available,
on terms acceptable to us and that are not dilutive to our stockholders.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     We recognize revenue in accordance with Statement of Position ("SOP") 97-2,
"Software Revenue Recognition," which provides guidance on recognizing revenue
from software transactions, as amended by SOP 98-4, "Deferral of the Effective
Date of a Provision of SOP 97-2, Software Revenue Recognition." We applied the
provisions of SOP 97-2 on a prospective basis for new software transactions
entered into as of January 1, 1998. The adoption of this guidance did not have a
material impact on our financial condition or results of operations.

     Further guidance was published during 1998 in SOP 98-9, "Modification of
SOP 97-2, Software Revenue Recognition, With Respect to Certain Transactions."
Additionally, the AICPA issued technical

                                       30
<PAGE>   34

questions and answers on financial and reporting issues related to SOP 97-2 in
January 1999. The adoption of this guidance is not expected to have a material
impact on our financial condition or results of operations.

QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

     We currently develop and market our products in the United States. As all
sales are currently made in U.S. dollars, a strengthening of the dollar could
make our product less competitive in foreign markets. Our interest income is
sensitive to changes in the general level of U.S. interest rates. Due to the
short-term nature of our investments, we believe that there is no material risk
exposure. Based on the foregoing, no quantitative disclosures have been
provided.

YEAR 2000 ISSUES

     We have completed our initial assessment of the potential overall impact of
the impending century change on our business, financial condition and operating
results. Based on our current assessment, we believe the current versions of our
applications are year 2000 ready -- that is, they are capable of adequately
distinguishing 21st century dates from 20th century dates. However, our
applications operate in complex network environments and directly or indirectly
interact with a number of other hardware and software systems that we cannot
completely evaluate for year 2000 readiness.

     We may face claims based on year 2000 problems in other companies'
products, or issues arising from the integration of multiple products within an
overall system, although we have not been a party to any litigation or
arbitration proceeding or services involving our applications related to year
2000 readiness issues or services. We may in the future be required to defend
our applications or services in such proceedings, or to negotiate resolutions of
claims based on year 2000 issues. The costs of defending and resolving year
2000-related disputes, regardless of the merits of such disputes, and any
liability we have for year 2000-related damages, including consequential
damages, could harm our business. In addition, we believe that the purchasing
patterns of customers and potential customers may be affected by year 2000
issues, as companies expend significant resources to correct or upgrade their
current software systems for year 2000 readiness. These expenditures may result
in reduced funds available to purchase applications and services like those we
offer. To the extent year 2000 issues cause a significant delay in, or
cancellation of, decisions to purchase our applications, services or product
offerings, our business would suffer.

     We have reviewed our internal management information and other critical
business systems to identify any year 2000 problems. We also have communicated
with the external vendors that supply us with material software and information
systems to determine their year 2000 readiness. Based on our vendors'
representations, we believe that the third-party hardware and software we use is
year 2000 ready.

     To date, we have not incurred any material costs directly associated with
year 2000 readiness efforts, except for compensation expense associated with
salaried employees who have devoted some of their time to year 2000 assessment
and remediation efforts. As discussed above, we do not expect the total cost of
year 2000 problems to be material to our business, financial condition and
operating results. However, we will continue to evaluate new versions of our
applications and services, software and information systems provided by third
parties, and any new infrastructure systems that we acquire, to determine
whether they are year 2000 ready. Despite our current assessment, we may not
identify and correct all significant year 2000 problems on a timely basis. Year
2000 readiness efforts may involve significant time and expense and unremediated
problems could harm our business, financial condition and operating results. We
currently have no contingency plans to address the risks associated with
unremediated year 2000 problems.

                                    BUSINESS

     The following description of our business should be read in conjunction
with the information included elsewhere in this prospectus. This description
contains certain forward-looking statements that are based largely on our
current expectations and are subject to a number of risks and uncertainties. Our
actual results could differ significantly from the results discussed in the
forward-looking statements as a result of certain of the factors set forth below
and elsewhere in this prospectus.

OVERVIEW

     XCare.net, Inc. is a leading provider of Internet-based,
business-to-business connectivity, information exchange and electronic commerce
solutions for health care. We have developed an Internet-based information and
transaction technology platform, which we call the XCare.net platform. Using the
XCare.net platform, we connect health care participants together into a
community structure and deliver applications, services and electronic commerce
product offerings that are designed to improve process efficiencies, reduce
administrative costs and create new revenue opportunities for our customers. The
XCare.net platform has been adopted by health care providers, payers and
suppliers. In addition, we have entered into strategic relationships that we
believe will enhance our portfolio of solutions, provide important specialized
industry expertise to us and our customers and create additional revenue
sources.

     We believe that the XCare.net platform is the first infrastructure based on
extensive mark-up language, or XML, using the Topic Navigation Mapping standard
that is specifically tailored to meet the demands of health care industry
participants. We expect XML to be a predominant protocol for exchanging data for
electronic commerce in the future. Topic Navigation Mapping provides a standard
format for indexing and structuring the XML-formatted content. We take advantage
of the benefits of both XML and Topic Navigation Mapping technologies to process
data previously trapped in legacy systems, allow for automation of health care
processes and integrate a wide variety of health care data including audio,
video and text.

Health Care Market Overview

     The U.S. Health Care Finance Administration estimates that health care
expenditures currently represent $1.2 trillion, or 14% of the U.S. economy, and
that these expenditures will increase to $2.0 trillion by 2007 due both to
rising health care costs and an aging population. Health care claims, which
totalled approximately 4.4 billion in 1998, generally are processed through
antiquated legacy systems via paper, fax or phone. These systems can be
inefficient and lead to unnecessary and duplicative costs. We believe that
providing new, Internet-based, business-to-business connectivity, information
exchange and electronic commerce solutions that effectively address processing
inefficiencies is one of the largest market opportunities in health care today.

                                       32
<PAGE>   36

     The health care industry is currently one of the most complex markets due
to the numerous interrelationships among health care participants.

                         Marketing Participants Graphic

     The payment for and delivery of health care requires that consistent,
accurate information be shared confidentially among health care participants
across a large and fragmented industry. Employers select health plans, determine
benefit levels, enroll employees and maintain employee eligibility data.
Individuals compare medical plans, choose physicians and submit claims for
reimbursement. Physicians, hospitals and other providers verify patient
eligibility, collect patient histories, order diagnostic tests and x-rays,
receive and interpret test results, render diagnoses, issue referrals and submit
claims to payers. Payers manage referrals, establish medical care protocols and
reimbursement policies and process claims. Laboratories analyze and process
patient samples or tests, provide results and submit claims for reimbursement.
Pharmacies fill prescriptions and submit claims for reimbursement. Medical
supply companies distribute medical devices and pharmaceutical supplies. These
health care transactions all are highly dependent on the collection and
communication of information, and each participant is dependent on the others
for portions of that information.

Market Characteristics

     Market fragmentation. The health care market is highly fragmented with wide
geographic dispersion, a large number of participants and significant
differences in technology infrastructure.

     - Geographic fragmentation. Because health care is delivered locally, there
       are hundreds of thousands of market participants in different locations.
       For example, there are approximately 750 HMOs in the United States,
       644,000 active physicians and 6,200 hospitals. Additionally, there are
       over 16,500 nursing homes, 8,000 home health agencies and 4,500
       independent laboratories.

                                       33
<PAGE>   37

     - Technological fragmentation. Information technology investment has not
       been coordinated among health care participants. Current technology
       infrastructure in health care is characterized by numerous, incompatible
       and, in many cases, antiquated legacy systems. Consequently,
       communication of information generally takes place via paper, fax and
       telephone.

     Complex processes. Health care is delivered in a marketplace which has
become increasingly complex given the transition to managed care, the
data-intensive nature of health care transactions, the lack of standard data
formats, the complicated procurement process and the pervasiveness of government
regulation.

     - Transition to managed care. One of the most important changes in the U.S.
       health care system since the 1980s has been the shift away from
       fee-for-service indemnity plans to managed care organizations. Currently,
       67.1% of the U.S. population is covered through some form of managed
       care, and we believe that this proportion is likely to increase. As
       managed care has become more prevalent and the number of payers has
       increased, provider reimbursement and general administration has become
       increasingly burdensome.

     - Intensive data management. Upkeep of health care data is largely a
       labor-intensive, paper-based and error-prone process in which data are
       manually collected, authenticated, edited, categorized and updated. For
       example, eligibility and plan information, which is basic information
       about an individual and his or her dependents, is cumbersome to manage,
       given that the data must be constantly updated to reflect any changes
       affecting coverage status, such as marriage, child births and address
       changes. However, this information is required at all points of health
       care delivery.

     - No standard data format or business rules. Data formats vary considerably
       throughout the health care industry and typically are unique to each
       particular health plan or provider. The data are stored in different
       formats and health care participants often rely on proprietary business
       rules for information such as plan coverage, eligibility and physician
       co-payments.

     - Complexity of procurement, purchasing and payment processes. There are
       numerous types of health care transactions due to the large number of
       both suppliers and buyers of care. In addition, there are multiple
       payment mechanisms depending on who has assumed the health care coverage
       risk. Payment mechanisms can range from fee-for-service to a fully
       insured health care maintenance organization, known as an HMO, and may be
       paid for by the individual, the individual's employer, the government, or
       a combination of all three.

     - Increasing government regulation. Numerous federal, state and local laws
       and regulations govern the health care industry, which change frequently
       depending on political and economic influences. For example, the Health
       Insurance Portability and Accountability Act of 1996 has recently placed
       substantial new administrative requirements on many health care
       participants, including rules regarding compliance with industry
       standards, data formats, portability of insurance and data security.

Current Health Care Market Issues

     As a result of the fragmentation and complexity of the health care market,
participants are unable to cost-effectively manage, communicate and exchange
information in real-time. This fragmentation and complexity has resulted in
increasing dissatisfaction among health care participants.

     - Inability to manage and exchange data. In order to achieve efficient
       delivery of health care, information must flow within and between health
       care participants. The enrollment and eligibility process requires shared
       employee information among employers, health plans and provider groups.
       The referral and authorization process involves physicians seeking
       approval from health plans and patients scheduling appointments with
       other physicians. To diagnose and treat patients, physicians need access
       to clinical information, such as medical history data or lab results,
       from various hospitals, laboratories or other providers. Prescription
       services require communication of

                                       34
<PAGE>   38

       medication histories and payer rules among patients, physicians, pharmacy
       benefit managers, pharmacies and payers. Finally, for the health care
       supply chain to generate and fulfill transactions, medical supply vendors
       and laboratories require information about the availability and pricing
       of supplies. The inability to transfer information between participants
       is exacerbated by the fact that several different data formats can exist
       even within one health plan.

     - Lack of real-time and secure communication. The current, paper-based
       processes do not allow for automated, daily workflow or the secure
       exchange of time-sensitive and critical information. This often results
       in administrative inefficiencies related to the manual retrieval of
       information, delivery of unnecessary care and the performance of
       redundant tests and procedures.

     - Rising costs. Despite payers' use of a number of techniques designed to
       control the cost of care and administration -- such as lowering
       reimbursement rates, shifting costs to providers and restricting coverage
       for services -- health care costs are continuing to escalate. To
       compensate for operating margin pressures, payers are raising premiums.
       This, in turn, is increasing the costs of health care for individuals and
       their employers.

Growth of the Internet and Applicability to Health Care

     The Internet has emerged as the fastest growing communication medium in
history. We estimate that the total number of Internet users worldwide will grow
from 150 million in 1998 to 500 million by 2003. The ubiquitous nature, low cost
and scalability of the Internet have created new opportunities for conducting
secure commerce. Recently, the widespread adoption of intranets and the
acceptance of the Internet as a business communications platform have created a
foundation for business-to-business electronic commerce that should enable
organizations to streamline complex processes, lower costs and improve
productivity.

     We believe that business-to-business electronic commerce represents a
significantly larger opportunity than business-to-consumer or person-to-person
electronic commerce. We believe that the Internet can serve as a catalyst to
lower the cost of business-to-business commerce and bring market participants
across industry lines together in more efficient and productive relationships.
Forrester Research, Inc. estimates that business-to-business electronic commerce
will grow from $43.1 billion in the United States in 1998 to $1.3 trillion in
2003 while business-to-consumer electronic commerce will grow from $7.8 billion
in 1998 to $108.0 billion in 2003.

     Although the Internet can speed and streamline transactions, we believe
that current Internet-based health care solutions are significantly limited in
their ability to search, structure, integrate and filter vast amounts of
disparate data and dynamically customize and display information in contexts
relevant to particular users. These limitations are particularly critical in the
health care industry, where information and transaction connectivity among all
participants is necessary to reduce process inefficiencies and costs. In order
for an Internet-based health care solution to be successful, we believe it must
contain the following key technology and business components:

     - a common, secure and scaleable platform for structuring information
       exchange and commerce among multiple market participants;

     - an effective and cost-efficient interface with legacy systems;

     - automation of health care transaction processes to reduce paper, improve
       work flow and streamline administration;

     - integration of disparate data from a variety of multimedia sources such
       as audio, video and written documents;

     - ability to dynamically retrieve and update data in a view customizable
       for each particular health care participant; and

     - quick returns on investment to facilitate adoption by health care
       participants.

OUR SOLUTION

     We are a leading provider of Internet-based, business-to-business
connectivity, information exchange and electronic commerce solutions for health
care. We have developed an Internet-based, information and transaction
technology platform, which we call the XCare.net platform. Using the XCare.net
platform, we connect health care participants together into a community
structure and deliver applications, services and electronic commerce product
offerings that are designed to improve process efficiencies, reduce
administrative costs and create new revenue opportunities for our customers. Our
applications consist of software modules facilitating health care transactions
such as eligibility checks, referrals and health plan enrollment. Our services
include formulating and implementing Internet strategies for our customers,
administering back office operations and operating and hosting their technology
environments in our electronic commerce operations center. We currently are
developing electronic commerce product offerings such as drug store products,
medical supplies and credit cards with smart card technology for claims payment.
We believe that the XCare.net platform and our solutions can reduce
administrative and transaction inefficiencies and simplify the way business is
conducted in health care, which may ultimately enhance the quality of health
care delivery in the U.S. We believe that our solutions have the following
advantages:

     Use of new standard for information exchange. The XCare.net platform and
associated applications and services are based on XML. We expect XML to be a
predominant protocol for exchanging multimedia data for information exchange and
electronic commerce on the Internet in the future. XML provides a rich document
structure that allows complex data from multiple sources to be dynamically
processed and displayed to users in personalized ways. We believe that these
capabilities are particularly applicable to the health care industry because XML
can process data previously trapped in legacy systems, allow for automation of
health care processes and integrate a wide array of health care data including
audio, video and text.

     Disciplined approach to creating customer solutions. We have developed a
step-by-step approach to assist our customers to envision, evaluate and execute
an Internet-based health care strategy. The resulting strategies are tailored to
the particular customer to improve efficiency, reduce costs and create new
opportunities for revenue generation.

     Complete, turnkey solutions. Our solutions are designed to provide a
comprehensive set of applications, services and product offerings while
preserving previous technology investments by integrating diverse multimedia
content, including content from legacy systems. These solutions are delivered in
a low cost, low maintenance environment provided through our electronic commerce
operations center.

     Value-added Solution Channels. Our business model is based on a
multi-faceted network of collaborative relationships, which we call Solution
Channels, among our company, our customers and our vendors. Our Solution
Channels leverage our customers' and vendors' core competencies to promote the
exchange of health care related services and products. XCare.net Solution
Channels create a community which enables our customers to also act as vendors
of applications, services and products to other XCare.net community
participants. Solution Channels allow us to:

     - Create new revenue opportunities for others. Customers and vendors can
       utilize our Solution Channels as distribution channels for existing as
       well as new products and services that allow them to generate new sources
       of incremental revenue. For example, we package our eXtensible CARE
       applications system with medical management and third party
       administration services provided by Employers Mutual, Inc. for
       distribution to members of the XCare.net community such as American
       Medical Pathways, Inc., a subsidiary of American Medical Response, Inc.

     - Identify new revenue opportunities for us. Our customers can produce
       complementary applications or services that operate on the XCare.net
       platform and enhance the value of the specific solutions we have
       developed. We can deliver these new applications and services to the
       XCare.net community through our Solution Channels, generating additional
       revenue for us. For

                                       36
<PAGE>   40

       example, we can license credentialing applications from one existing
       customer, and then resell these applications through our Solution
       Channels to other community members.

     - Establish growing communities connected through the XCare.net
       platform. Our customers can extend the scope and reach of the XCare.net
       platform by distributing our applications, services and product offerings
       to their customers. By leveraging our customer base as channels for wider
       deployment of our solutions, we encourage increased usage of the
       XCare.net platform as well as extend the community to new users.

STRATEGY

     Our objective is to become the leading provider of health care solutions
for Internet-based, business-to-business connectivity, information exchange and
electronic commerce. Our strategy focuses on the following:

     Cross-sell applications, services and electronic commerce product offerings
in our Solution Channels. We believe that our Solution Channels represent an
opportunity for deploying new applications, services and electronic commerce
product offerings that are either internally developed or obtained through our
growing number of customer and vendor relationships. We intend to continue to
sell additional applications, services and product offerings to existing
customers. We believe this cross-selling approach simplifies the sales process
and may shorten our sales cycle and reduce our cost of sales.

     Penetrate target market segments. We estimate that there are approximately
12,000 entities operating within the payer/third-party administrator and at-risk
provider market segments. We intend to penetrate these markets because these
potential customers are well positioned to influence and drive change in health
care processes. We believe that these organizations have both the funding to
adopt new Internet-based process improvements and the incentive to lower ongoing
operating costs in order to improve their margins.

     Develop new applications, services and product offerings. We have developed
a variety of applications, services and product offerings to address operational
inefficiencies in the health care industry. We are also developing additional
applications and services and are planning new product offerings that we expect
to launch commercially during the next six to 12 months. As Internet strategies
in the health care industry evolve and new relationships between organizations
are formed, we intend to continue to identify new development opportunities.

     Leverage existing applications, services and product offerings. We seek to
identify key functions that are critical to particular industry participants and
develop solutions supporting these functions. We intend to regularly review
existing applications, services and product offerings to extend their
functionality, transaction capabilities and features as customer needs dictate.
In addition, we may modify existing solutions to pursue new market
opportunities. We plan to accomplish this by building XML-based applications
encompassing the identified functionality, by acquiring businesses or
technologies, by enabling industry-leading, third-party applications to operate
on our platform, and by increasing our product offerings. We have initially
targeted those needs we believe are most critical to each business segment of
the health care industry, offer the highest value to health care participants
and are readily adaptable to our XCare.net platform.

     Form strategic relationships with leading health care participants. We are
aggressively pursuing strategic relationships with leaders in key health care
industry segments to increase our portfolio of applications, services and
product offerings, to increase the scope of our XCare.net community of users and
to provide specialized industry expertise for new solutions. We believe this
will result in accelerated market awareness and demand for our applications,
services and product offerings, through the influence of these partners both
directly, through their use of our solutions and sales efforts, and indirectly,
through their relationships with other potential customers.

                                       37

TECHNOLOGY

     We believe that the XCare.net platform is the first XML-based
infrastructure using the Topic Navigation Mapping standard that is specifically
tailored to meet the demands of health care industry participants. Unlike the
current Internet standard, hypertext mark-up language, or HTML, XML in
combination with Topic Navigation Mapping allows a higher degree of flexibility
for customized data exchange between health care participants. We expect XML to
be a predominant protocol for exchanging multimedia data for information
exchange and electronic commerce in the future. Topic Navigation Mapping
provides a standard format for indexing and structuring the XML formatted
content. We call the resulting indices and structures Topic Maps. We take
advantage of the benefits of both XML and Topic Navigation Mapping technologies
to process data previously trapped in legacy system allow for automation of
health care processes and integrate a wide variety of health care data including
data in audio, video and text form.

     We use a set of software applications, known as brokering components, to
find, integrate and present relevant, customized information to individual
users.

                                    Graphic

     Context Broker. The Context Broker acts as a user's personal information
manager and transaction assistant. It stores information about the user and
learns personal preferences. With each use, the Context Broker further refines a
user's personal preferences, and, as a result, the user's experience with the
Web site is continually tailored to his or her particular needs based on current
and past sessions. As the user moves from one transaction to another, the
Context Broker also ensures that information is carried through and remains
consistent across multiple transactions.

                                       38
<PAGE>   42

     DataFabric. The DataFabric is a map formed by linking data and weighting
relationships. This fabric filters out irrelevant information and allows for
more intelligent searching.

     LogicFabric. The LogicFabric is a map assembled by the rules and workflow
associated with the data relationships. This fabric provides the order and
assembly instructions for the information.

     Semantic Broker. The Semantic Broker is responsible for interpreting a
user's request and finding the relevant information. It does this by reading the
DataFabric and LogicFabric for interpretation, location and assembly
instructions. It then dispatches the Service Broker to obtain the information
from any location throughout the Web. The final integration of data may involve
multi-media content, transactions and associated rules and workflow.

     Service Broker. The Service Broker is the gateway out to the Internet,
locating and collecting the information as specified by the Semantic Broker. The
Service Broker then returns the information to the Context Broker, which
presents the relevant information in a manner customized to individual users.

     The technology components which comprise our platform are developed using
the Oracle 8i relational database management system, Enterprise JavaBeans
programming language and Object Store, a global object-oriented database
management system. To support the ability of our technology platform to enable
and facilitate electronic commerce, we have built and maintain an electronic
commerce operations center designed for high performance, scalability and
stability utilizing Sun Microsystems, Inc.'s Solaris operating system.

     Our platform architecture was designed for use in highly confidential,
health care computing environments where security is a high priority. A Web
server authenticates the identity of the end-users to ensure only authorized
end-users have access to our Web applications. Users are authenticated by a
valid user identification and password, a security token or a digital
certificate, or a certificate authority. We address data security using digital
certificate technology signed with private keys and verified with public keys.

     Our facilities and operations utilize redundancy and back-up to minimize
exposure to systems failure. Telecommunications and server infrastructures
support redundant processing and data back-up capabilities. Our routine back-up
procedures are performed incrementally on a daily basis with a full system
back-up performed monthly. In addition, we use RAID5 systems which provide
real-time back-up of data. All back-ups are maintained in fire proof storage
with critical support information. Technical and operations support staff are
available on a 24-hours-a-day, seven-days-a-week basis to assist with any
critical processing incidents or failures.

     The XCare.net platform provides our customers with the capability to scale
their solutions as their business grows. This scalability can extend these
solutions across multiple organizations in diverse geographic settings
supporting high volumes of users. Our flexible XML-based technology brokering
architecture can also accommodate high volumes of transactions and dynamic
customization for the multiple participants within the health care marketplace.

STRATEGIC RELATIONSHIP

     We have entered into a strategic relationship with ADIS International, Ltd
that we believe will enhance our application portfolio, provide important
specialized industry expertise and create additional revenue sources. ADIS
International Ltd, a subsidiary of Wolters Kluwer, focuses on development of
drug/disease clinical decision support tools deployed through Internet-based
technology. We have collaborated with ADIS International Ltd on the introduction
of its ClinAssist product. In addition, ADIS International Ltd provided clinical
expertise to assist us in the creation of our Topic Navigation Mapping
technology. Finally, we are co-developing a new Web site supporting the
ClinAssist product.

SALES AND MARKETING

     Sales. We sell our products and services through our direct sales and
business development groups, targeting the payer/third-party administrator and
risk-bearing provider segments of the health care market. Our sales office is
located at our principal offices in Englewood, Colorado. The direct sales
process involves the generation of sales leads through direct marketing,
tele-prospecting, public relations, Web advertising and promotion, attendance
and presentations at major health care and technology-oriented trade shows and
industry conferences. The time between initial customer contact and an actual
sales order may span three months or more. See "Risk Factors -- Our operating
results may vary significantly due to the lengthy sales and implementation
cycles for our products and services.

     In addition, our direct sales and business development groups use our
Solution Channels to cultivate strategic relationships with our customers and
vendors to encourage them to provide value-added applications, services and
products for redistribution through the network of users of the XCare.net
platform.

                                       42
<PAGE>   46

     Marketing. Our primary marketing initiatives include public relations,
direct mail and outreach programs to customers and vendors. We use our Web site,
www.xcare.net, to establish our market presence, generate leads and extend our
program offerings to health care industry participants.

     As of September 30, 1999, we had 11 employees in sales and marketing
functions.

CUSTOMER SUPPORT

     We believe that a high level of customer support is necessary to achieve
wide acceptance of our solutions. We provide a range of customer support
services through our staff of customer service personnel, multiple call centers
and an e-mail help desk all of which are available 24 hours a day, seven days a
week and are frequently updated to improve existing information and to support
new services. We also employ technical support personnel who work directly with
our direct sales force and customers of our applications and services. We
provide our customers with the ability to purchase maintenance for our
applications and services, which includes technical support and upgrades. We
also provide training programs for our customers. As of September 30, 1999, we
had 22 employees in addition to independent contractors in customer support
functions.

RESEARCH AND DEVELOPMENT

     As of September 30, 1999, our development and engineering group consisted
of 11 employees divided into Topic Navigation Mapping, XML and infrastructure
groups. For the years ended December 31, 1996, 1997 and 1998, we incurred $3.2
million, $4.2 million and $670,000 in research and development expenses
respectively. In addition, for the six month period ended June 30, 1999, we had
incurred $161,000 in research and development expenses. We believe that timely
development of new and enhanced applications and technology is necessary to
remain competitive in the marketplace. Accordingly, we intend to continue
recruiting and hiring experienced development personnel and to make investments
in development and engineering.

COMPETITION

     The emerging Internet-based health care market is undergoing rapid
technological change. The ubiquitous reach of the Internet, coupled with the
availability and acceptability of new Internet-based technologies, has created
significant opportunities in health care for both legacy and new Internet-based
system vendors. Potential competitors fall into three primary categories: health
care Internet companies focused on providing connectivity and transactions
within business-to-business and business-to-consumer frameworks; traditional
health care information system vendors who seek to extend the services of their
core products using Internet-based technology; and traditional managed care
information system and outsourcing vendors who generally sell legacy systems and
are focusing on extending the services of their core products to the Internet.
In addition, from time to time our customers may develop products and services
competitive with those offered by us.

     We believe that our main competitors are Healtheon Corporation, CareInsite,
Inc., IDX Systems Corporation, McKesson HBOC Inc., and Computer Sciences
Corporation, and that the principal competitive factors in the Internet-based
health care market are:

     - the ability of technology to integrate data from legacy systems and other
       multimedia content;

     - the timeliness and price of new applications, services and electronic
       commerce product offerings;

     - the degree of customer service offered to purchasers of Internet health
       care solutions;

     - the scope of industry knowledge and familiarity with needs of health care

INTELLECTUAL PROPERTY

     We seek to protect our software, documentation and other written materials
primarily through a combination of trade secret, trademark and copyright laws,
confidentiality procedures and contractual provisions. For example, we license
rather than sell our software applications and require licensees to enter into
license agreements that impose certain restrictions on the licensees' ability to
utilize the software code. In addition, we seek to avoid disclosure of our trade
secrets, by, among other things, requiring those persons with access to our
proprietary information to execute confidentiality agreements with us and
restricting access to our source code.

     We intend to file patent applications in the United States with respect to
certain aspects of our content brokering technology. Despite our efforts to
protect our proprietary rights, unauthorized parties may attempt to copy aspects
of our products or obtain and use information that we regard as proprietary.
Policing unauthorized use of our products is difficult. While we are unable to
determine the extent to which piracy of our products exists, software piracy can
be expected to be a persistent problem, particularly in foreign countries where
the laws may not protect our proprietary rights as fully as in the United
States.

     From time to time, we may be involved in intellectual property disputes. We
have not been notified that any of our products infringe the proprietary rights
of third parties. However, in the future, third parties may claim infringement
against us with respect to current or future products. We expect that providers
of Internet health care solutions will increasingly be subject to infringement
claims as the number of products and competitors in our industry grows and
traditional suppliers of health care data and transaction solutions begin to
offer Internet-based products. See "Risk Factors -- Our proprietary technology
may be subjected to infringement claims or may be infringed upon."

     We rely upon software we have licensed from Sinclair Montrose Healthcare
PLC to perform key functions of our MatchNet Staffing & Scheduling product. We
currently have an exclusive license to the software, although exclusivity may
terminate if we are unable to meet milestones. This license may not continue to
be available to us on commercially reasonable terms. The loss of this license
could result in delays or reductions of shipments of the MatchNet Staffing &
Scheduling application until equivalent software could be identified, developed,
licensed and integrated. See "Risk Factors -- If we lose key licenses we may be
required to develop or license alternative technology which may cause delays, at
considerable expense or reduce sales."

GOVERNMENT REGULATION

Standards

     The Health Insurance Portability and Accountability Act of 1996 mandates
the use of standard transactions, standard identifiers, security and other
provisions by the year 2000. We are designing our XCare.net platform and
solutions to enable compliance with the proposed regulations. However, until
such regulations become final, they could change, which could require us to
expend additional resources to comply with the revised standards. In addition,
the success of our compliance efforts may be dependent on the success of health
care participants in dealing with the standards.

Confidentiality

     The confidentiality of patient records and the circumstances under which
such records may be released for inclusion in our databases are subject to
substantial regulation by state governments. These state laws and regulations
govern both the disclosure and the use of confidential patient medical record
information. Additional legislation governing the dissemination of medical
record information has been proposed at both the state and federal level. This
legislation may require holders of such information to implement security
measures that may require substantial expenditures by us. Changes to state or
federal

                                       44
<PAGE>   48

laws may materially restrict the ability of health care providers to submit
information from patient records using our applications.

     We utilize an architecture that incorporates a secured socket layer
encryption which surpasses required security protection. Additionally the use of
firewalls and other security schemes assure customers of a compliant and secure
computing environment. Additionally, we utilize a formal, authority-based use of
digital certificates to assure the identity of electronic trading partners. For
support of identification requirements we utilize an exchange of passwords and
identities by U.S. certified mail or telephonic identification. If unauthorized
persons were to gain access to patient records notwithstanding our efforts to
maintain their security, this could result in our liability for these security
breaches and damage to our reputation.

Third Party Administration and Utilization Review Licensure and Registration

     Certain of the administrative services we provide health plans, payers and
providers, including our third-party administration and utilization review
operations, are regulated by the statutes and regulations of various states and
require that we obtain appropriate licensure or registration. We believe that we
are in substantial compliance with the licensing and registration laws of each
state in which we conduct business.

False Claims Act

     Under the federal False Claims Act, liability may be imposed on any
individual or entity who knowingly submits or participates in submitting claims
for payment to the federal government which are false or fraudulent, or which
contain false or misleading information. Liability may also be imposed on any
individual or entity who knowingly make or use a false record or statement to
avoid an obligation to pay the federal government. Various state laws impose
liability for similar acts. Claims under the federal False Claims Act may be
brought by the federal government or private whistleblowers. If we are found
liable for a violation of the federal False Claims Act, or any similar state
law, it may result in substantial civil and criminal penalties. In addition, we
could be prohibited from processing Medicaid or Medicare claims for payment.

Prompt Payment Laws

     Various states have passed laws regarding the prompt payment of medical
claims by health plans. If a claim is brought against us and we are found to
have violated a law regarding the prompt processing of claims for payment, we
may incur civil or other penalties.

Government Investigations

     There is increasing scrutiny by law enforcement authorities, the U.S.
Department of Health and Human Services Office of Inspector General, the courts
and Congress of agreements between health care providers and suppliers or other
contractors which have a potential to increase utilization of government health
care resources. In particular, scrutiny has been placed on the coding of claims
for payment and contracted billing arrangements. Investigators have demonstrated
a willingness to look beyond the formalities of business arrangements to
determine the underlying purposes of payments between health care participants.
Although, to our knowledge, neither we nor any of our customers is the subject
of any investigation, we cannot tell whether we or our customers will be the
target of governmental investigations in the future.

Regulation of the Practice of Medicine and Other Health Care Professions

     The practices of medicine, nursing and pharmacology are generally defined
by state law and vary from state to state. These practices require a license
under state law and, depending on state law, practicing without a license can be
a civil or criminal violation. We have endeavored to structure our

                                       45
<PAGE>   49

existing operations to be in substantial compliance with state health care
professional licensing requirements. However, the application of this area of
the law to Internet services such as ours is new. Also, we have not conducted a
state by state survey of licensing requirements and policies. Accordingly, a
state regulatory authority and/or one or more licensed professionals or advocacy
groups or consumers may allege that one or more elements of our business
requires a license to practice under existing or future laws or statutes. Any
application of professional practice regulations to our business could
negatively impact our business. Further, liability based on a determination that
we engaged in a professional practice without a license may cause us to be
excluded from coverage under the terms of our current general liability
insurance policy and may also subject us to a higher standard of care than would
be applicable to activities which do not require a professional license.

Regulation of Pharmacy Prescription Drug Activities

     The business of providing prescription drugs and other medical products is
subject to federal, state and local regulations, many of which are specific to
pharmacies. In addition, the Federal Trade Commission and many state agencies
regulate advertising and product performance claims for prescription drugs.
Pharmacy operations are subject to federal, state and local licensing and
registration regulations with respect to the Controlled Substances Act and
federal Drug Enforcement Agency regulations, as well as related state and local
laws and regulations relating to pharmacy operations, including registration,
security, recordkeeping, and reporting requirements related to the purchase,
storage and dispensing of controlled substances, prescription drugs and certain
over-the-counter drugs.

     The U.S. House of Representatives Committee on Commerce and the General
Accounting Office are currently investigating online pharmacies and online
prescribing, especially focusing on those who prescribe drugs online and
pharmacies that fill invalid prescriptions, including those that are written
online. The committee on commerce requested that the General Accounting Office
undertake a formal review of a number of issues pertaining to online pharmacies,
including an assessment of mechanisms to ensure that online pharmacies are
obeying the various state and federal regulations for the industry. In addition,
various state legislatures are considering new legislation related to the
regulation of nonresident pharmacies. The inclusion of prescription drugs as a
Medicare benefit has been the subject of numerous bills in the U.S. Congress.

     Should we commence providing prescription drugs to consumers, we will be
required to comply with many of the laws, regulations and initiatives described
above. These efforts may require the commitment of additional resources by us.

Federal and State Anti-Kickback Laws

     Provisions of the Social Security Act, which are commonly known as the
Federal Anti-Kickback Law, prohibit knowingly or willfully, directly or
indirectly, paying or offering to pay, or soliciting or receiving, any
remuneration in exchange for the referral of patients to a person participating
in, or for the order, purchase or recommendation of items or services that are
subject to reimbursement by, Medicare, Medicaid and similar other federal or
state healthcare programs. Violations may result in civil and criminal sanctions
and penalties. Applications, services or product offerings. If any of our health
care communications or electronic commerce activities were deemed to be
inconsistent with the Federal Anti-Kickback Law or with state anti-kickback or
illegal remuneration laws, we could face civil and criminal penalties or be
barred from such activities. Further, we could be required to restructure our
existing or planned sponsorship compensation arrangements and electronic
commerce activities in a manner which could harm our business.

Regulation of the Sale of Over-the-Counter Drugs, Nutritional Supplements,
Cosmetics and Medical Devices

     The U.S. Food and Drug Administration and Federal Trade Commission and
similar state agencies regulate drug and cosmetic advertising and promotion,
including direct-to-consumer advertising, done by

                                       46
<PAGE>   50

or on behalf of drug and cosmetic manufacturers and marketers. In addition, the
Federal Trade Commission regulates product safety for nutritional supplements as
well as over-the-counter drugs, medical devices and prescription drugs. In the
event that we provide such products or services, we will be subject to U.S. Food
and Drug Administration and Federal Trade Commission regulation and enforcement
for false advertising and misleading advertising, including overstatements
regarding product performance, especially regarding nutritional supplements.
While we have rights against the manufacturer as to adulteration issues and
product claims to the extent we have received the claims from the manufacturer,
we may have liability if the manufacturer cannot or will not indemnify us in a
specific situation.

FDA Regulation of Medical Devices

     The FDA is responsible for assuring the safety and effectiveness of medical
devices under the Federal Food, Drug and Cosmetic Act. Computer applications and
software are considered medical devices and subject to regulation by the FDA
when they are indicated, labeled or intended to be used in the diagnosis of
disease or other conditions, or in the cure, mitigation, treatment or prevention
of disease, or are intended to affect the structure or function of the body. We
do not believe that any of our current applications, services or product
offerings are subject to FDA jurisdiction or regulation; however, we may expand
our applications, services and offerings into areas that may subject it to FDA
regulation. We have no experience in complying with FDA regulations and
compliance with FDA regulations could prove to be time consuming, burdensome and
expensive, which could impede our ability to introduce new applications,
services or product offerings in a timely manner.

     Please see "Risk Factors -- Government regulation of health care may impact
our business" for more information regarding the risks government regulation
pose for our business.

LEGAL PROCEEDINGS

     There are no material legal proceedings pending against us. We could become
involved in litigation from time to time relating to claims arising out of our
ordinary course of business.

EMPLOYEES

     As of September 30, 1999, we had a total of 57 employees, of whom 22 are
engaged in professional services and customer support functions, 11 in product
development, seven in the electronic commerce operations center, 11 in sales and
marketing and six in management, finance and administration. None of our
employees is represented by a labor union. We have not experienced any work
stoppages, and we consider our relations with our employees to be good.

     Our future performance depends in significant part upon the continued
service of our key personnel, none of whom is bound by an employment agreement
requiring service for any defined period of time. Our future success also
depends on our continued ability to attract, integrate, retain and motivate
highly qualified sales, technical and managerial personnel. Competition for such
qualified personnel is intense. See "Risk Factors -- Our executive officers and
key personnel are critical to our business and these officers and key personnel
may not remain with us in the future."

FACILITIES

     Our principal executive and corporate offices are located in Englewood,
Colorado, in approximately 7,812 square feet of subleased office space under a
sublease that expires on November 30, 1999 as to 3,667 square feet and December
2002 as to 4,145 square feet. We believe that the lease expiring on November 30,
1999 can be extended on commercially reasonable terms. We also maintain an
electronic commerce operations center in Albuquerque, New Mexico, in 6,800
square feet of subleased office space under a lease that expires in January
2000. We believe our space is adequate for our current operations and that
additional leased space can be obtained on commercially reasonable terms if
needed.

BOARD OF DIRECTORS AND COMMITTEES

three years. At each annual meeting of stockholders, directors will be elected
to succeed those directors whose terms are expiring. Daniel J. Mitchell is the
Class I director whose term expires in 2000. William F. Reilly, James B. Hoover
and Robert Tsao are Class II directors whose terms will expire in 2001. Jeffrey
M. Krauss, J. Andrew Cowherd and Lorine R. Sweeney are Class III directors whose
terms will expire in 2002.

     The board of directors has a compensation committee and an audit committee.
The compensation committee, which is comprised of James B. Hoover, J. Andrew
Cowherd and Robert Tsao, administers the stock option plan and all matters
concerning executive compensation. The audit committee, which is comprised of
Daniel J. Mitchell, Jeffrey M. Krauss and William F. Reilly, approves the
selection of XCare.net's independent auditors, reviews the results and scope of
annual audits and other accounting related services, and evaluates our internal
audit and control functions. Each of these committees was established in July
1999.

DIRECTOR COMPENSATION

     We do not pay any cash compensation to directors for serving in that
capacity. The board has the discretion to grant options to non-employee
directors pursuant to the director plan. In September 1999, each director other
than Lorine R. Sweeney, our President and Chief Executive Officer, was granted
an option to purchase 100,000 shares of common stock. See "Management -- 1999
Director Option -- Director Plan" and "Certain Transactions."

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The compensation committee is currently comprised of Messrs. Hoover,
Cowherd and Tsao. None of these individuals has at any time been an officer or
employee of XCare.net. Prior to formation of the compensation committee, all
decisions regarding executive compensation were made by the full board. No
interlocking relationship exists between the board of directors or compensation
committee and the board of directors or compensation committee of any other
company, nor has any such interlocking relationship existed in the past.

LIMITATION ON LIABILITY AND INDEMNIFICATION MATTERS

     Our certificate of incorporation limits the liability of directors to the
maximum extent permitted by Delaware law. Delaware law provides that directors
of a corporation will not be held personally liable for monetary damages for
breach of their fiduciary duties as directors, except for breaches of the
director's duty of loyalty to XCare.net or its stockholders, acts or omissions
not in good faith or that involve intentional misconduct or a knowing violation
of law, unlawful payments of dividends or

                                       50
<PAGE>   54

unlawful stock repurchases, redemptions or other distributions, and transactions
from which a director derives an improper personal benefit.

     Our bylaws provide that we must indemnify our directors and executive
officers and may indemnify our other officers and employees and agents to the
fullest extent permitted by law. We believe that indemnification under our
bylaws covers at least negligence and gross negligence on the part of
indemnified parties. Our bylaws also permit us to obtain insurance on behalf of
any officer, director, employee or other agent for any liability arising out of
his or her actions in such capacity, regardless of whether the bylaws would
permit indemnification.

     We have entered into agreements to indemnify our directors and officers, in
addition to indemnification provided for in our bylaws. These agreements, among
other things, provided that we will indemnify each of our directors and officers
for various expenses, including attorneys' fees, judgments, fines and settlement
amounts incurred by them in any action or proceeding, including any action by or
arising out of their services as one of our directors or officers, any
subsidiaries or any other company or enterprise to which he or she provides
services at our request. In addition, we intend to obtain directors' and
officers' insurance providing indemnification for our directors and officers. We
believe that these provisions, agreements and insurance are necessary to attract
and retain qualified directors and officers.

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

EXECUTIVE COMPENSATION

     The following table sets forth information concerning the compensation that
we paid during the year ended December 31, 1998 to our Chief Executive Officer
and the only other executive officers whose salary and bonus exceeded $100,000
during such fiscal year.

OPTION GRANTS IN LAST FISCAL YEAR

     The following table sets forth certain information with respect to stock
options granted in 1998 to each of the officers named in the above table,
including the potential realizable value over the ten-year term of the options,
based on assumed rates of stock appreciation of 5% and 10%, compounded annually.
These assumed rates of appreciation comply with the rules of the Securities and
Exchange Commission and do not represent our estimate of our future stock price.
Actual gains, if any, on stock option exercises will be dependent on the future
performance of our common stock.

     In 1998, we granted options to purchase an aggregate of 11,206,000 shares
to employees, directors and consultants. All options were granted under our
stock option plan at exercise prices equal to the fair market value of our
common stock on the date of grant, as determined in good faith by our board of
directors, based on our financial results and prospects and at the share prices
paid in arms-length transactions. All options typically vest over four years and
are exercisable for up to ten years. In July 1999, we amended our option
agreements so that all options are immediately exercisable upon grant; however,
any unvested shares are subject to repurchase by us at their cost in the event
of the optionee's termination of employment.

OPTION EXERCISES AND HOLDINGS

     The following table sets forth for each of the named officers information
concerning exercisable and unexercisable options held as of December 31, 1998.
The value of in-the-money options is based on a value of $0.025 per share, the
fair market value of our common stock at December 31, 1998, as determined by our
board, and net of the option exercise price.

     The number of unexercised options at December 31, 1998 which are
exercisable reflects an amendment to the option agreements effected in July 1999
so that all options are immediately exercisable upon grant.

EMPLOYMENT AGREEMENTS

     We require each of our employees to enter into confidentiality agreements
prohibiting the employee from disclosing any of our confidential or proprietary
information. In addition, the agreements generally

                                       52
<PAGE>   56

provide that upon termination the employee will not work for a competitor and
may not solicit our customers and employees. At the time of commencement of
employment, our employees also generally sign offer letters specifying basic
terms and conditions of employment. Each of Lorine R. Sweeney, Mark Rangell and
Tammy McLaren have signed offer letters with of this type, see "Certain
Transactions -- Offers of Employment."

1997 STOCK PLAN

     Our stock plan provides for the grant of incentive stock options to
employees, including officers and employee directors, and for the grant of
nonstatutory stock options and stock purchase rights to employees, officers,
directors and consultants. The stock plan was adopted by our board of directors
in March 1997 and approved by the stockholders in March 1997. The board of
directors approved amendments to the stock plan to increase the number of shares
reserved under the stock plan in December 1997, April 1998, July 1998, May 1999
and September 1999. The stockholders also approved these amendments to the stock
plan in December 1997, April 1998, July 1998, May 1999 and September 1999.

     As of September 30, 1999 a total of 22,000,000 shares of our common stock
has been reserved for issuance under the stock plan. As of September 30, 1999,
options to purchase 14,914,921 shares of common stock were outstanding under the
stock plan and 5,413,454 were available for future issuance.

     Unless terminated sooner, the stock plan terminates in 2007.

     The administrator of our stock plan has the power to determine among other
things:

     - the terms of the options or stock purchase rights granted, including
       exercise price;

     - the number of shares subject to each option or stock purchase right;

     - the exercisability of each option or stock purchase right; and

     - the form of consideration payable upon the exercise of each option or
       stock purchase right.

     In addition, the administrator has the authority to amend, suspend or
terminate the stock plan, so long as no such action affects any shares
previously issued or any option previously granted under the stock plan. During
any fiscal year, no optionee may be granted options to purchase more than
10,500,000 shares, although, in connection with an optionee's initial employment
with us, such optionee may be granted an option covering an additional
10,500,000 shares.

     Options and stock purchase rights granted under our stock plan are
generally not transferable by the optionee, and each option and stock purchase
right is exercisable during the lifetime of the optionee only by the optionee.
Options granted under the stock plan must generally be exercised within three
months after the end of the optionee's status as an employee, director or
consultant of XCare.net, or within 12 months after termination by death or
disability, but in no event later than the expiration of the option's term.

     In the case of stock purchase rights, unless the administrator determines
otherwise, we retain a repurchase option exercisable upon the voluntary or
involuntary termination of the purchaser's employment or consulting relationship
with XCare.net for any reason, including death or disability. The repurchase
price is the original price paid by the purchaser and may be paid by
cancellation of any indebtedness of the purchaser to XCare.net. The repurchase
option shall lapse at a rate determined by the administrator.

     The exercise price of all incentive stock options granted under the stock
plan must be at least equal to the fair market value of the common stock on the
date of grant. The exercise price of nonstatutory stock options and stock
purchase rights is determined by the administrator, but for nonstatutory stock
options intended to qualify as "performance-based compensation" under Section
162(m) of the Internal Revenue Code, the exercise price must be at least equal
to the fair market value of our common stock on the date of grant. For any
participant who possesses more than 10% of the voting power of all
                                       53
<PAGE>   57

classes of the our outstanding stock, the exercise price of any incentive stock
option must be at least equal to 110% of the fair market value on the grant date
and the term of the incentive stock option must not exceed five years. The term
of all other options granted under the stock plan may not exceed ten years.

     The stock plan provides that if we merge with another corporation, or sell
substantially all our assets, each option and stock purchase right will be
assumed or an equivalent option will be substituted by the successor
corporation. If the outstanding options and stock purchase rights are not
assumed or substituted for, the optionees will become fully vested in and have
the right to exercise their options or stock purchase rights in full. In such
case, the administrator will notify the optionees that their options or stock
purchase rights are fully exercisable for a period of 15 days from the date of
the notice, and the options or stock purchase rights will terminate upon the
expiration of that period.

1999 EMPLOYEE STOCK PURCHASE PLAN

     Our employee stock purchase plan was adopted by our board of directors in
October 1999, and will be submitted to our stockholders for approval in November
1999, although it will not become effective until the date of this offering. A
total of 3,500,000 shares of our common stock has been reserved for issuance
under the 1999 purchase plan.

     The employee stock purchase plan, which is intended to qualify under
Section 423 of the Internal Revenue Code, contains consecutive, overlapping, 12
month offering periods. Each offering period includes two six-month purchase
periods. The offering periods generally start on the first trading day on or
after November 1 and May 1 of each year, except for the first offering period,
which commences on the first trading day on or after the effective date of this
offering and ends on the last trading day on or before April 30, 2001.

     Employees are eligible to participate if they are customarily employed by
us for at least 20 hours per week and more than five months in any calendar
year. However, employees may not participate in the employee stock purchase plan
if at the beginning of a purchase period, they own 5% or more of the total
combined voting power or value of all classes of our stock. In addition, no
employee may participate in the employee stock purchase plan at a rate which
would exceed $25,000 worth of stock in any calendar year.

     The employee stock purchase plan permits employees to purchase our common
stock through payroll deductions of up to 15% of the employee's "compensation."
Compensation is defined as the employee's base straight time gross earnings and
commissions, but excluding payments for overtime, profit sharing payments, shift
premium payments, incentive compensation and bonuses. The maximum number of
shares a participant may purchase during a single purchase period is 20,000
shares.

     Amounts deducted and accumulated by the participant are used to purchase
shares of common stock at the end of each purchase period. The price of stock
purchased is generally 85% of the lower of the fair market value of our common
stock either at the beginning of the offering period or at the end of that
purchase period. In the event the fair market value at the end of a purchase
period is less than the fair market value at the beginning of the offering
period, all participants will be withdrawn from the current offering period
following exercise and automatically re-enrolled in a new offering period. The
new offering period will use the lower fair market value as of the first date of
the new offering period to determine the purchase price for future purchase
periods.

     Participants may end their participation at any time during an offering
period, and they will be paid their payroll deductions to date. Participation
ends automatically upon termination of employment.

     Rights granted under the employee stock purchase plan are not transferable
by a participant other than by will, the laws of descent and distribution, or as
otherwise provided under the employee stock purchase plan. The employee stock
purchase plan provides that, in the event we merge with another corporation or
sell substantially all of our assets, each outstanding option may be assumed or
substituted for by the successor corporation. If the successor corporation
refuses to assume or substitute for the
                                       54
<PAGE>   58

outstanding options, the offering period then in progress will be shortened and
a new exercise date will be set.

     The employee stock purchase plan will terminate in 2009. Our board of
directors has the authority to amend or terminate the employee stock purchase
plan, except that no such action may adversely affect any outstanding rights to
purchase stock under the employee stock purchase plan.

1999 DIRECTOR OPTION PLAN

     All non-employee directors are entitled to participate in our director
option plan. The director option plan was adopted by our board of directors in
October 1999 and will be submitted to our stockholders for their approval in
November 1999, although it will not become effective until the date of this
offering. The director option plan has a term of ten years, unless terminated
sooner by our board of directors. A total of 1,750,000 shares of our common
stock have been reserved for issuance under the 1999 director option plan.

     The director option plan generally provides for an automatic initial grant
of an option to purchase 175,000 shares of our common stock to each non-employee
director on the date that person first becomes a non-employee director. After
the initial grant, a non-employee director will automatically be granted
subsequent options to purchase 70,000 shares of our common stock each year on
the date of our annual stockholder's meeting, if on such date he or she has
served on our board of directors for at least six months. Each initial option
grant and each subsequent option has a term of 10 years. Each initial option,
vests as to 25% of the shares subject to the option on each anniversary of the
date of grant, and each subsequent option grant vests as to 100% of the shares
subject to the option on the first anniversary of the date of grant. The
exercise price of all options will be 100% of the fair market value of our
common stock on the date of grant.

     The director option plan provides that if we merge with another
corporation, or sell substantially all our assets, each option will become fully
vested and exercisable for a period of thirty days from the date our board of
directors notifies the optionee of the option's full exercisability, after which
period the option will terminate. Options granted under the director option plan
must be exercised within three months of the end of the optionee's tenure as a
director of the Company, or within 12 months after termination by death or
disability, but in no event later than the expiration of the option's ten year
term. Options granted under the director option plan are not transferable by the
optionee other than by will or the laws of descent and distribution, and each
option is exercisable, during the lifetime of the optionee, only by the
optionee.

401(K) PLAN

     We have a 401(k) plan covering full-time employees located in the United
States who are at least 21 years of age. The 401(k) plan is intended to qualify
under Section 401(k) of the Internal Revenue Code. Contributions to the 401(k)
plan by employees or by us, and the investment earnings on these contributions,
are not taxable until withdrawn from the 401(k) plan. Employees may elect to
reduce their pre-tax earnings up to a statutorily prescribed annual limit, which
was $10,000 in 1998, and to have the amount of that reduction contributed to the
401(k) plan. The 401(k) plan permits, but does not require, additional matching
contributions by us on behalf of all participants in the 401(k) plan. To date,
we have not made any contributions to the 401(k) plan.

                              CERTAIN TRANSACTIONS

     Since January 1996, there has not been nor is there currently proposed any
transaction or series of similar transactions to which we were or are to be a
party in which the amount involved exceeds $60,000 and in which any of our
directors, executive officers, holders of more than five percent of our stock or
any member of their immediate families had or will have a direct or indirect
material interest other than compensation agreements and other arrangements,
which are described where required in "Management," and the transactions
described below.

EQUITY INVESTMENT TRANSACTIONS

     On March 12, 1997, we sold an aggregate of 2,450,000 shares of our Series A
convertible preferred stock at a price per share of $2.86. In June and July
1999, we sold an aggregate of 63,053,144 shares of our Series B convertible
preferred stock at a price per share of $0.27, including 11,867,959 shares of
Series B convertible preferred stock issued upon conversion of convertible
promissory notes. Upon the closing of this offering, all shares of preferred
stock will be converted into shares of common stock. The holders of Series A
convertible preferred stock are entitled to convert their shares into an
aggregate of 28,028,000 shares of common stock, based on a conversion price of
$0.25 per common share. The holders of Series B convertible preferred stock are
entitled to convert their holdings into an equal number of shares of common
stock, based on a conversion price of $0.27 per common share. Listed below are
those directors, executive officers and stockholders who beneficially own five
percent or more of our securities who participated in the preferred stock
financings. We believe that the shares issued in these transactions were sold at
the then fair market value and that the terms of these transactions were no less
favorable than we could have obtained from unaffiliated third parties.

                             PRINCIPAL STOCKHOLDERS

     The following table sets forth information with respect to beneficial
ownership of our common stock as of September 30, 1999, as adjusted to reflect
the sale of common stock in this offering, the conversion of our outstanding
convertible preferred stock, including convertible preferred stock issuable upon
the assumed exercise of all outstanding convertible preferred stock warrants,
and the exercise of all outstanding common stock warrants with exercise prices
below an assumed initial public offering price. Information is given for:

     - each person who is known by us to beneficially own more than five percent
       of our common stock;

     - each of our directors;

     - each of our officers; and

     - all of our directors and officers as a group.

     Percentages of the outstanding shares of common stock are based on
103,559,087 shares outstanding as of September 30, 1999, plus all shares of
common stock issuable on exercise of options within 60 days of September 30,
1999 held by the particular beneficial owner.

                          DESCRIPTION OF CAPITAL STOCK

     Upon the closing of the offering, our authorized capital stock will consist
of                shares of common stock, $0.01 par value, and 5,000,000 shares
of preferred stock, $0.01 par value.

     The following summary of provisions of the common stock and preferred stock
does not purport to be complete and is subject to, and qualified in its entirety
by, the provisions of our certificate of incorporation, which is included as an
exhibit to the registration statement of which this prospectus is a part, and by
the provisions of Delaware law.

COMMON STOCK

     After giving effect to the conversion of all previously outstanding
preferred stock into shares of common stock and the assumed cashless exercise of
all outstanding common stock warrants and convertible preferred stock warrants
with exercise prices below an assumed initial public offering price and the
conversion of the convertible preferred stock issued upon the assumed exercise
of the latter warrants into common stock, as of September 30, 1999, there were
103,559,087 shares of common stock outstanding held of record by approximately
  stockholders. There will be           shares of common stock outstanding,
assuming no exercise of the underwriters' over-allotment option and no exercise
of outstanding options after September 30, 1999, after giving effect to the sale
of common stock in this offering.

     The holders of common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of stockholders. Subject to
preferences that may be applicable to any outstanding shares of preferred stock,
the holders of common stock are entitled to receive ratably any dividends
declared by the board of directors out of funds legally available for the
payment of dividends. See "Dividend Policy." In the event of a liquidation,
dissolution or winding up of XCare.net, the holders of common stock are entitled
to share ratably in all assets, subject to prior distribution rights of the
preferred stock, if any, then outstanding. Holders of common stock have no
preemptive rights or rights to convert their common stock into any other
securities. There are no redemption or sinking fund provisions applicable to the
common stock. All outstanding shares of common stock are fully paid and
non-assessable, and the shares of common stock to be issued in the offering will
be fully paid and non-assessable.

PREFERRED STOCK

     Upon the consummation of the offering, each share of convertible preferred
stock outstanding prior to this offering will automatically convert into common
stock. The Series A convertible preferred stock will each convert into 11.44
shares of common stock. The Series B convertible preferred stock will each
convert into one share of common stock. Pursuant to our certificate of
incorporation, after the offering our board of directors has the authority,
without further action by the stockholders, to issue up to 5,000,000 shares of
preferred stock in one or more series and to fix the designations, powers,
preferences, privileges, which may be greater than the rights of the common
stock. The board, without stockholder approval, can issue preferred stock with
voting, conversion or other rights that could adversely affect the voting power
and other rights of the holders of common stock. Preferred stock could thus be
issued quickly with terms calculated to delay or prevent a change in control of
XCare.net or to make removal of management more difficult. Additionally, the
issuance of preferred stock may have the effect of decreasing the market price
of the common stock. At present, we have no plans to issue any preferred stock.

REGISTRATION RIGHTS

     Upon completion of this offering, the holders of an aggregate of
approximately 97,987,462 shares of common stock will be entitled to certain
rights with respect to the registration of such shares under the Securities Act
of 1933. Under the terms of the registration rights agreements, if we propose to

                                       62
<PAGE>   66

register any of our securities under the Securities Act, either for our own
account or for the account of other security holders exercising registration
rights, the holders of registration rights are entitled to notice of such
registration and are entitled to include shares of common stock in the
registration. The rights are subject to conditions and limitations, among them
the right of the underwriters of the offering subject to the registration to
limit the number of shares included in such registration. Holders of these
rights may also require us to file a registration statement under the Securities
Act at our expense with respect to their shares of common stock, and we are
required to use our best efforts to effect that registration, subject to
conditions and limitations. Furthermore, stockholders with registration rights
may require us to file additional registration statements on Form S-3, subject
to conditions and limitations.

DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER PROVISIONS

     Delaware Anti-Takeover Statute. We are subject to Section 203 of the
Delaware General Corporation Law. In general, these provisions prohibit a
Delaware corporation from engaging in any business combination with any
interested stockholder for a period of three years following the date that the
stockholder became an interested stockholder, unless the transaction in which
the person became an interested stockholder is approved in a manner presented in
Section 203 of the Delaware General Corporation Law. Generally, a "business
combination" is defined to include mergers, asset sales and other transactions
resulting in financial benefit to a stockholder. In general, an "interested
stockholder" is a person who, together with affiliates and associates, owns, or
within three years, did own, 15% or more of a corporation's voting stock.

     Certificate of Incorporation. In October 1999, our stockholders approved
amendments to our certificate of incorporation, to provide:

     - That the board of directors may issue, without further action by the
       stockholders, up to 5,000,000 shares of undesignated preferred stock

     - That any action to be taken by our stockholders must be effected at a
       duly called annual or special meeting and not by a consent in writing

     - For the division of the board of directors into three classes, with each
       class serving for a term of three years

     - That vacancies on the board, including newly created directorships, can
       be filled only by a majority of the directors then in office

     - That directors may be removed only for cause

     Bylaws. In October 1999, our board approved amendments to our bylaws to
provide that special meetings of our stockholders may be called only by the
chairman of the board, the president or the board.

     These provisions are intended to enhance the likelihood of continuity and
stability in the composition of the board and in the policies formulated by the
board and to discourage certain types of transactions that may involve an actual
or threatened change of control of XCare.net. These provisions also are designed
to reduce our vulnerability to an unsolicited proposal for a takeover of
XCare.net that does not contemplate the acquisition of all of its outstanding
shares or an unsolicited proposal for the restructuring or sale of all or part
of XCare.net. These provisions, however, could discourage potential acquisition
proposals and could delay or prevent a change in control of XCare.net. They may
also have the effect of preventing changes in our management.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is ChaseMellon
Shareholder Services L.L.C.

                        SHARES ELIGIBLE FOR FUTURE SALE

     Prior to this offering, there has been no market for our common stock.
Future sales of substantial amounts of common stock in the public market could
adversely affect the prevailing market price from time to time. Furthermore,
because only a limited number of shares will be available for sale shortly after
this offering as a result of contractual and legal restrictions on resale, sales
of substantial amounts of common stock in the public market after the
restrictions lapse could cause the prevailing market price of our common stock
to fall and impede our ability to raise equity capital in the future.

     Upon completion of the offering, we will have outstanding an aggregate of
          shares of common stock, assuming no exercise of the underwriters'
over-allotment option and no exercise of outstanding options after September 30,
1999. Of these outstanding shares, the           shares sold in the offering
will be freely tradable without restriction or further registration under the
Securities Act of 1933 unless purchased by "affiliates" of XCare.net as that
term is defined in Rule 144 under the Securities Act. The remaining
shares of common stock outstanding upon completion of the offering will be
"restricted shares," as that term is defined in Rule 144 under the Securities
Act. Restricted shares may be sold in the public market only if registered or if
they qualify for an exemption from registration under Rules 144, 144(k) or 701
promulgated under the Securities Act, which rules are summarized below, or
another exemption. Sales of the restricted shares in the public market, or the
availability of such shares for sale, could adversely affect the market price of
our common stock.

     We have has agreed not to sell or otherwise dispose of any shares of common
stock or any securities convertible into or exercisable or exchangeable for
common stock, or enter into any swap or similar agreement that transfers, in
whole or in part, the economic risk of ownership of the common stock, for a
period of 180 days after the date of this prospectus, without the prior written
consent of BancBoston Robertson Stephens. In addition, all officers, directors
and certain other holders of common stock have entered into contractual
"lock-up" agreements providing that they will not offer, sell, contract to sell
or grant any option to purchase or otherwise dispose of shares of common stock
owned by them or that could be purchased by them through the exercise of options
for a period of 180 days after the date of this prospectus without the prior
written consent of BancBoston Robertson Stephens. As a result of these
contractual restrictions, notwithstanding possible earlier eligibility for sale
under the provisions of Rules 144, 144(k) and 701, additional shares will be
available for sale in the public market as follows:

     - No shares of common stock will be eligible for sale as of the effective
       date of the offering

     - No additional shares will be eligible for sale beginning 90 days after
       the effective date of the offering

     -              additional shares will be eligible for sale beginning 180
       days after the effective date of the offering, subject in some cases to
       certain volume limitations

     Of the           remaining restricted shares:

     -              shares are subject to a repurchase option of XCare.net in
       the event of termination of employment

     -              shares will not be eligible for sale pursuant to Rule 144
       until the expiration of a one-year holding period in        2000

Rule 144

     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
common stock for at least one year

                                       65
<PAGE>   69

would be entitled to sell, within any three-month period, a number of shares
that does not exceed the greater of:

     - 1% of the number of shares of common stock then outstanding, which will
       equal approximately              shares immediately after this offering;
       or

     - the average weekly trading volume of our common stock on the Nasdaq Stock
       Market's 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 other requirements regarding
the manner of sale, notice filing and the availability of current public
information about us.

Rule 144(k)

     Under Rule 144(k), a person who is not deemed to have been one of our
"affiliates" at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
generally including the holding period of any prior owner other than an
"affiliate," is entitled to sell such shares without complying with the manner
of sale, notice filing, volume limitation or notice provisions of Rule 144.
Therefore, unless otherwise restricted, "144(k) shares" may be sold immediately
upon the completion of this offering.

Rule 701

     In general, under Rule 701, any of our employees, directors, officers,
consultants or advisors who purchase shares from us in connection with a
compensatory stock or option plan or other written agreement before the
effective date of this offering is entitled to resell such shares 90 days after
the date of this offering in reliance on Rule 144, without having to comply with
certain restrictions, including the holding period, contained in Rule 144.

     The SEC 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 Securities Exchange Act of 1934, along with the shares acquired upon
exercise of these options (including exercises after 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 offering, may be sold by persons other than "affiliates," as defined in
Rule 144, subject only to the manner of sale provisions of Rule 144. Securities
issued in reliance on Rule 701 may be sold by "affiliates" under Rule 144
without compliance with its one year minimum holding period requirement.

Registration on Form S-8

     We intend to file a registration statement under the Securities Act
covering the shares of common stock subject to outstanding options or reserved
for issuance under the 1997 stock option plan, employee stock purchase plan and
the director option plan. This registration statement is expected to be filed as
early as the effectiveness of the registration statement covering the shares of
common stock offered in this offering and will automatically become effective
upon filing. Shares registered under this registration statement will, subject
to Rule 144 volume limitations applicable to affiliates and the expiration of
any 180-day contractual lockup period, be available for sale in the open market,
except to the extent that these shares are subject to vesting restrictions.

     We 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 us as set forth on the cover page of this prospectus. The common
stock is offered by the underwriters as stated herein, subject to receipt and
acceptance by them and subject to their right to reject any order in whole or in
part.

     The underwriters have advised us that they do not expect sales to
discretionary accounts to exceed five percent of the total number of shares
offered.

Over-Allotment Option

     We 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 we will receive for the
shares that the underwriters have agreed to purchase. To the extent that the
underwriters exercise this 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. We 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. If such
option is exercised in full, the total public offering price, underwriting
discounts and commissions and proceeds to us will be $          , $          and
$          , respectively.

Indemnity

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

Lock-Up Agreements

     Each of our executive officers, directors and shareholders and
substantially all of optionholders have agreed with the representatives, for a
period of 180 days after the date of this prospectus, 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, with certain exceptions, thereafter acquired
directly by such holders or with respect to which they have or hereafter acquire
the power of disposition, without the prior written consent of BancBoston
Robertson Stephens Inc. However, BancBoston Robertson Stephens Inc. may, in its
sole discretion and at any time without notice, release all or any portion of
the securities subject to the lock-up agreements. There are no agreements
between the representatives and any of our shareholders providing consent by the
representatives to the sale of shares prior to the expiration of the period of
180 days after this prospectus.

Future Sales

     In addition, we have agreed that during the period of 180 days after this
prospectus, we will not, subject to certain exceptions, without the prior
written consent of BancBoston Robertson Stephens Inc.:

     - Consent to the disposition of any shares held by shareholders prior to
       the expiration of the period of 180 days after this prospectus; or

     - 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.

Directed Shares

     We have requested that the underwriters reserve up to   % of the shares of
common stock for sale at the initial public offering price to individuals
designated by us.

No Prior Public Market

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

Stabilization

     The representatives have advised us that, pursuant to Regulation M under
the Securities Act, certain persons participating in this offering may engage in
transactions, including stabilizing bids, syndicate covering transactions or the
imposition of penalty bids, that may have the effect of stabilizing or
maintaining the market price of the common stock at a level above that which
might otherwise prevail in the open market. A "stabilizing bid" is a bid for or
the purchase of the 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 the common stock on behalf of the
underwriters

                                       68
<PAGE>   72

to reduce a short position incurred by the underwriters in connection with this
offering. A "penalty bid" is an arrangement permitting the representatives to
reclaim the selling concession otherwise accruing to an underwriter or syndicate
member in connection with this offering if the common stock originally sold by
such underwriter or syndicate member is purchased by the representatives in a
syndicate covering transaction and has therefore not been effectively placed by
such underwriter or syndicate member. The representatives have advised us that
such transactions may be effected on the Nasdaq National Market or otherwise
and, if commenced, may be discontinued at any time.

                       CHANGE IN INDEPENDENT ACCOUNTANTS

     Effective September 1, 1999, PricewaterhouseCoopers LLP was engaged as our
independent accountants and replaced KPMG LLP, who were dismissed as our
independent accountants on August 25, 1999. The decision to change accountants
was approved by our Board of Directors. The audit reports of KPMG LLP for the
years ended December 31, 1997 and 1996 contained no adverse opinion or
disclaimer of opinion and were not qualified or modified as to uncertainty,
audit scope or accounting principle, except that the audit report issued by KPMG
LLP for the year ended December 31, 1997 included an explanatory paragraph
citing factors that raised substantial doubt surrounding our ability to continue
as a going concern. In connection with its audits through December 31, 1997 and
through August 25, 1999, there were no disagreements with KPMG LLP on any matter
of accounting principles or practices, financial statements disclosure or
auditing scope or procedures, which disagreements, if not resolved to their
satisfaction would have caused them to make reference in connection with their
opinion to the subject matter of the disagreement. KPMG LLP has not audited or
reported on any of the financial statements or information included in this
prospectus. For purposes of this filing, the financial statements for the years
ended December 31, 1997 and 1996 as well as the financial statements for the
year ended December 31, 1998 have been audited by PricewaterhouseCoopers LLP.
Prior to September 1, 1999, we had not consulted with PricewaterhouseCoopers LLP
on items that involved our accounting principles or the form of audit opinion to
be issued on our financial statements.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholders and Board of Directors of XCare.net, Inc.

     In our opinion, the accompanying balance sheet and the related statements
of operations, of changes in stockholders' equity (deficit) and of cash flows
present fairly, in all material respects, the financial position of XCare.net,
Inc. at December 31, 1997 and 1998 and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 1998, in
conformity with generally accepted accounting principles. 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 of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                       NOTES TO THE FINANCIAL STATEMENTS

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization

     XCare.net, Inc. (the "Company") develops, deploys and supports
business-to-business software solutions for the health care industry. The
Company's proprietary XML-based platform and professional services allow it to
create customizable transaction-based application solutions that are designed to
address the complex administrative processing requirements of health care
companies. In addition, the Company provides outsourcing and transaction hosting
services that improve workflow processes and reduce administrative costs for
customers.

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 reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

Revenue Recognition

     For contracts entered into subsequent to January 1, 1998, the Company
recognizes revenue in accordance with the provisions of Statement of Position
97-2, "Software Revenue Recognition". The Company derives revenue from license
fees and related services under the terms of fixed price contracts. Maintenance
revenue is derived from agreements for supporting and providing periodic updates
to licensed software. Consulting revenue consists of revenue from consulting
services provided pursuant to time and materials contracts. Transaction
processing revenue is derived from outsourcing and transaction hosting services
and is recognized on a per-transaction basis as services are performed.

     License fees and related services revenue is generally recognized from
fixed price contracts using the percentage-of-completion method of accounting
where collectibility of fees is reasonably assured. Where collectibility of fees
is not reasonably assured, the Company defers revenue and related costs as
deferred contract costs and recognizes revenue and cost of revenue as cash is
collected.

     The Company may encounter budget and schedule overruns on fixed price
contracts caused by increased material, labor or overhead costs. Adjustments to
cost estimates are made in the periods in which the facts requiring such
revisions become known. Estimated losses, if any, are recorded in the period in
which current estimates of total contract revenue and contract costs indicate a
loss. The Company does not require collateral for its receivables and an
allowance is maintained for potential credit losses.

     Maintenance revenue is recorded as unearned revenue and is recognized
ratably over the service period, which is generally 12 months. When maintenance
is bundled with the original license fee arrangement, its fair value is deferred
and recognized during the period such services are provided.

     Revenue from consulting services provided pursuant to time-and-materials
contracts is recognized as the services are performed.

     For contracts entered into prior to January 1, 1998, the Company recognized
revenue in accordance with Statement of Position 91-1, "Software Revenue
Recognition." The Company's revenue recognition for such pre-1998 contracts was
substantially the same as that discussed above.

                 NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)

Cash and Cash Equivalents

     All highly liquid investments with a maturity of three months or less when
purchased are considered to be cash equivalents. All cash equivalents are
carried at cost, which approximates fair value.

Fair Value of Financial Instruments

     The Company's financial instruments include cash, accounts receivable,
prepaids, accounts payable and accrued liabilities. The carrying amounts of
financial instruments approximate fair value due to their short maturities.
Additionally, based upon the borrowing rates currently available to the Company
for debt agreements with similar terms and average maturities, management
believes the carrying amount of its debt approximates fair value.

Concentration of Credit Risk

     The Company performs ongoing evaluations of its customers' financial
condition and, generally, requires no collateral from its customers. All such
customers operate in the health care industry.

     The Company had the following customers which accounted for greater than
10% of each respective period's revenue:

<TABLE>

   F         --       --       11%
</TABLE>

     At December 31, 1998, customer's D, E and F accounted for 20%, 23% and 10%
of accounts receivable, respectively. Two other customers accounted for 27% and
13% of accounts receivable at December 31, 1998.

Property and Equipment

     Property and equipment are recorded at cost and depreciated using
straight-line methods over the estimated useful lives of the related assets,
ranging from two to five years. Equipment under capital lease arrangements as
well as leasehold improvements are amortized over the shorter of their useful
lives or the terms of the related leases.

Long-Lived Assets and Impairments

     The Company periodically evaluates the carrying value of long-lived assets,
including, but not limited to, purchased software, property and equipment, and
other assets, when events and circumstances warrant such a review. The carrying
value of a long-lived asset is considered impaired when the anticipated
undiscounted cash flow from such asset is separately indentifiable and is less
than its carrying value. In that event, a loss is recognized based on the amount
by which the carrying value exceeds the fair value of the long-lived asset. Fair
value is determined primarily using the anticipated cash flows discounted at a
rate commensurate with the risk involved. Loss on long-lived assets to be

                 NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)

disposed of is determined in a similar manner, except that fair values are
reduced for the cost to dispose.

Unaudited Pro Forma Stockholders' Equity

     In accordance with the requirements of the Securities and Exchange
Commission ("SEC"), which provide that the total redemption value of Series A
and B mandatorily redeemable convertible preferred stock (the "Convertible
Preferred Stock") be excluded from stockholders' equity (deficit), the
redemption value of the Convertible Preferred Stock has been reflected in the
accompanying balance sheet as mandatorily redeemable convertible preferred
stock.

     The board of directors has authorized management of the Company to file a
registration statement with the SEC permitting the Company to sell shares of its
common stock to the public. If the Company's initial public offering (the "IPO")
is consummated under the terms currently anticipated, all outstanding shares of
Convertible Preferred Stock will convert into 67,007,070 shares of common stock
of the Company. Unaudited Pro Forma Stockholders' Equity as of June 30, 1999, as
set forth in the accompanying balance sheet, is adjusted to reflect such
conversion, the assumed "cashless exercise" of all outstanding common stock
warrants and Series A mandatorily redeemable convertible preferred stock
warrants with exercise prices below the assumed initial public offering price,
and the conversion of the Series A mandatorily redeemable convertible preferred
stock issued upon the assumed exercise of the latter warrants into common stock,
resulting in the issuance of 73,913,388 additional shares of common stock.

Research and Development

     Research and development expense includes costs incurred by the Company to
develop and enhance the Company's software. Research and development costs are
charged to expense as incurred.

Advertising

     The Company expenses advertising costs as incurred. Advertising expenses
for the years ended December 31, 1996, 1997 and 1998 were approximately $98,000,
$433,000 and $66,000, respectively.

Software Development Costs

     Software development costs are required to be expensed until the point that
technological feasibility of the product is established, after which time such
costs are capitalized until general availability of the product. The period
between achieving technological feasibility and the general availability of such
software has historically been short. Consequently, costs otherwise
capitalizable after technological feasibility have historically been immaterial
and therefore expensed as incurred.

Purchased software

     Purchased software is held for resale under an exclusive license and is
capitalized and amortized ratably over a three-year estimated life. Accumulated
amortization was $0 and $142,000 (unaudited) as of December 31, 1998 and June
30, 1999, respectively. See Note 8.

Income Taxes

     Deferred income taxes are recognized for the tax consequences in future
years of differences between the tax bases of assets and liabilities and their
financial reporting amounts at each year end based on enacted tax laws and
statutory tax rates applicable to the periods in which the differences are

                                       F-9
<PAGE>   83
                                XCARE.NET, INC.

                 NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)

expected to affect taxable earnings. Valuation allowances are established when
necessary to reduce deferred tax assets to the amount more likely than not to be
realized. Income tax expense is the tax payable for the period and the change
during the period in deferred tax assets and liabilities.

Stock Option Compensation

     Stock option compensation expense is recognized in accordance with
Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
Employees.

Net Income (Loss) Per Share

     Net income (loss) per common share is calculated in accordance with SFAS
No. 128, "Earnings per Share" and SEC Staff Accounting Bulletin No. 98 ("SAB
98"). Under the provisions of SFAS No. 128 and SAB 98, basic net income (loss)
per common share is computed by dividing the net income (loss) for the period by
the weighted average number of common shares outstanding during the period.
Diluted net income (loss) per common share is computed by dividing the net
income (loss) for the period by the weighted average number of common and
potential shares outstanding during the period if their effect is dilutive.
Potential common shares consist of incremental common shares issuable upon the
exercise of stock options and warrants and upon conversion of the Convertible
Preferred Stock and convertible promissory notes.

Unaudited Pro Forma Net Income (Loss) Per Common Share

     The Company has computed unaudited pro forma basic net loss per common
share in accordance with the methodology in SFAS No. 128. The Company's
historical capital structure is not indicative of its prospective structure due
to the automatic conversion of all shares of Convertible Preferred Stock into
common stock concurrent with the closing of the Company's anticipated IPO.
Accordingly, historical basic net income (loss) per common share should not be
used as an indicator of future earnings per common share.

     Unaudited pro forma basic net loss per common share is computed using the
weighted average number of common shares outstanding during the period. The
Company has assumed the conversion of all outstanding Convertible Preferred
Stock issued into common stock for all periods presented on a weighted average
share basis and the assumed "cashless exercise" of all outstanding common stock
warrants and Series A mandatorily redeemable convertible preferred warrants with
exercise prices below the assumed initial public offering price, and the
conversion of the Series A mandatorily redeemable convertible preferred stock
issued upon the assumed exercise of the latter warrants into common shares as if
such transactions occurred at the beginning of the respective period or at the
date of original issuance, if later.

were excluded from historical basic and diluted loss per common share because of
their anti-dilutive effect.

Comprehensive Income

     Effective January 1, 1998, the Company adopted the provisions of SFAS No.
130, "Reporting Comprehensive Income." SFAS No. 130 establishes standards for
reporting comprehensive income and its components in financial statements.
Comprehensive income includes all changes in equity during a period from
non-owner sources. During each of the three years ended December 31, 1998, and
the six-month periods ended June 30, 1998 and 1999, the Company has not had any
significant transactions that are required to be reported as adjustments to
determine comprehensive income.

Unaudited Interim Financial Statements

     The accompanying interim financial statements as of and for the six-month
periods ended June 30, 1998 and 1999 are unaudited. In the opinion of the
Company, the unaudited interim financial statements have been prepared on the
same basis as the audited financial statements and reflect all adjustments,
consisting only of normal recurring adjustments, necessary for the fair
presentation of the results of the

interim periods. The financial data and other information disclosed in these
notes to financial statements for the related periods are unaudited. The results
of operations for the interim periods are not necessarily indicative of the
results to be expected for any future periods.

Stock Split

     On March 15, 1997, the Company effected a 600-for-one split of its common
stock. All references to shares, share prices and per share amounts have been
adjusted to reflect the stock split.

Recent Accounting Pronouncements

     The Company recognizes revenue in accordance with Statement of Position
("SOP") 97-2, "Software Revenue Recognition," which provides guidance on
recognizing revenue from software transactions, as amended by SOP 98-4,
"Deferral of the Effective Date of a Provision of SOP 97-2, Software Revenue
Recognition." The Company applied the provisions of SOP 97-2 on a prospective
basis for new software transactions entered into as of January 1, 1998. The
adoption of this guidance did not have a material impact on the Company's
financial condition or results of operations.

     Further guidance was published during 1998 in SOP 98-9 "Modification of SOP
97-2, Software Revenue Recognition, With Respect to Certain Transactions."
Additionally, the AICPA issued technical questions and answers on financial and
reporting issues related to SOP 97-2 in January 1999. The adoption of this
guidance will not have a material impact on the Company's financial condition or
results of operations.

     Certain equipment financing agreements recorded as capital lease
obligations are subject to restrictive covenants contained in the credit
agreement that require XCare.net to maintain certain financial ratios. XCare.net
was not in compliance with the covenants as of December 31, 1998 and June 30,
1999 and obtained a waiver of compliance for all covenants through September 30,
1999. The capital lease obligations under the financing agreements that included
the restrictive covenants were paid off during September 1999.

                 NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)

     On December 29, 1997 and April 10, 1998, the Company entered into bridge
loan agreements with its preferred stockholders. The loan agreements provided
for commitments for $2,500,000 of financing (the "1997 Convertible Promissory
Notes"), of which $500,000 was received in 1997. The remaining $2,000,000 was
received throughout 1998. In June 1999, the 1997 Convertible Promissory Notes
plus accrued interest aggregating approximately $2,924,000 converted at $0.27
per share into 10,831,800 shares of Series B mandatorily redeemable convertible
preferred stock in conjunction with the sale of Series B mandatorily redeemable
convertible preferred stock. In connection with the 1997 Convertible Promissory
Notes, the Company issued warrants to purchase 437,062 shares of the Company's
Series A mandatorily redeemable convertible preferred stock at $0.25 per share.
The warrants expire in 2002 through 2003 or upon an IPO, if earlier. The value
assigned to the warrants of $84,000, determined using a Black-Scholes option
pricing model, resulted in additional debt discount which is being amortized to
interest expense over the period that the Convertible Promissory Notes are
outstanding.

     In November 1998, the Company entered into a second bridge loan agreement
with its preferred stockholders. The loan agreement provided for $265,000
financing of which $230,000 was received in 1998 and $35,000 was received in
1999 (the "1998 Convertible Promissory Notes"). In June 1999, the 1998
Convertible Promissory Notes plus accrued interest aggregating approximately
$280,000 converted at $0.27 per share into 1,036,159 shares of Series B
mandatorily redeemable convertible preferred stock in conjunction with the sale
of Series B mandatorily redeemable convertible preferred stock. In connection
with the 1998 Convertible Promissory Notes, the Company issued warrants to
purchase 2,000,000 shares of the Company's common stock at $0.01 per share. The
warrants expire in 2003 or upon an IPO, if earlier. The value assigned to the
warrants of $43,000 resulted in additional debt discount which is being
amortized to interest expense over the period that the Convertible Promissory
Notes are outstanding.

4.  STOCKHOLDERS' EQUITY

Mandatorily Redeemable Convertible Preferred Stock

     In March 1997, the Company issued 2,450,000 shares of $.01 par value Series
A mandatorily redeemable convertible preferred stock and received proceeds net
of issuance costs totaling approximately $6,622,000.

     In June 1999, the Company issued 27,111,111 shares of $.01 par value Series
B mandatorily redeemable convertible preferred stock and received proceeds net
of issuance costs totaling $7,320,000. Concurrently, outstanding Convertible
Promissory Notes plus accrued interest of approximately $3,204,000 in the
aggregate were converted into an additional 11,867,959 shares of Series B
mandatorily redeemable convertible preferred stock.

     In July 1999, the Company issued 24,074,074 shares of $.01 par value Series
B mandatorily redeemable convertible preferred stock and received proceeds net

     The holders of the Convertible Preferred Stock have the following rights
and preferences:

Voting Rights

     The holders of the Convertible Preferred Stock and the common stock, voting
together as a single class, are entitled to vote upon any matter submitted to
the shareholders. The holders of the Convertible Preferred Stock are entitled to
one vote for each share of common stock that such holder would be entitled to
receive if the Convertible Preferred Stock were converted into common stock. The
holders of common stock have one vote per share of common stock.

                 NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)

Dividends

     The holders of the Series A mandatorily redeemable convertible preferred
stock are entitled to receive, out of funds legally available, dividends payable
at amounts equal to the equivalent per share dividend declared on the common
stock. Holders of Series B mandatorily redeemable convertible preferred stock
are entitled to receive noncumulative dividends at the per annum rate of
$0.00216 per share, when and if declared by the board of directors. No dividends
have been declared to date.

Liquidation

     In the event of any liquidation, dissolution or winding up of the Company,
the holders of Series A mandatorily redeemable convertible preferred stock were
entitled to receive up to five times their original cost in the event of
liquidation. In June 1999, pursuant to the closing of the Series B mandatorily
redeemable convertible preferred stock, the Company's board of directors revised
the terms whereby holders of Series A mandatorily redeemable convertible
preferred stock are entitled to receive an amount of $2.86 per share plus any
declared but unpaid dividends prior to and in preference to any distribution to
the holders of common stock. The holders of the Series B mandatorily redeemable
convertible preferred stock are entitled to receive an amount of $0.27 per share
plus any declared but unpaid dividends prior to and in preference to any
distribution to the holders of common stock. The remaining assets, if any, shall
be distributed ratably among the holders of common stock. Should the Company's
legally available assets be insufficient to satisfy the liquidation preferences,
the funds will be distributed among the holders of Convertible Preferred Stock
in proportion to the number of common shares into which each share of
Convertible Preferred Stock is convertible.

Conversion

     The 2,450,000 outstanding shares of Series A mandatorily redeemable
convertible preferred stock are convertible at the option of the holder into
28,028,000 shares of common stock. Each of the 38,979,070 shares of Series B
mandatorily redeemable convertible preferred stock are convertible at the option
of the holder into one share of common stock. Each share of Convertible
Preferred Stock automatically converts into common stock upon the closing of a
public offering at a per share price of at least $0.95 with gross proceeds of
greater then $15,000,000.

Redemption Rights

     As of January 1, 2002, 2003 and 2004, each holder of the Convertible
Preferred Stock has the individual right to require the Company to redeem the
holder's shares by paying in cash $2.86 per share of Series A Convertible
Preferred Stock and $0.27 per share of Series B Convertible Preferred Stock, for
up to a maximum on each such date of one-third of the total shares of
Convertible Preferred Stock outstanding. The redemption value of the mandatorily
redeemable convertible preferred stock is being accreted ratably over the period
from issuance of the redemption dates which approximates the effective interest
method.

Stock Warrants

     In conjunction with the Series A mandatorily redeemable convertible
preferred stock offering, the Company issued warrants to purchase a total of
122,500 shares of common stock for $3.15 per share. The value assigned to these
warrants using a Black-Scholes option pricing model was immaterial. The warrants
are exercisable immediately and expire in 2005 or upon an IPO, if earlier.

     In connection with the issuance of the 1997 Convertible Promissory Notes,
warrants to purchase 437,062 shares of the Company's Series A mandatorily
redeemable convertible preferred stock at

$0.25 per share were issued to the promissory noteholders. The warrants expire
December 2002 through April 2003 or upon an IPO, if earlier, and are convertible
into 4,999,988 shares of common stock.

     In connection with the issuance of the 1998 Convertible Promissory Notes,
warrants to purchase 2,000,000 shares of the Company's common stock at $0.01 per
share were issued to the promissory noteholders. The warrants expire November
and December of 2003 or upon IPO, if earlier.

     As of June 30, 1999, all warrants remain outstanding.

5. CONTRACT TERMINATIONS AND RELATED CHARGES

     During 1996, a major customer terminated its contract with the Company and
paid $2.3 million to settle all claims arising from the termination. During
1997, another major customer terminated its contract with the Company and paid
$250,000 to settle all claims associated with the termination.

     As a result of these contract terminations, during 1997, the Company
abandoned an operating lease and incurred impairment charges for related fixed
assets aggregating $887,000.

6. EMPLOYEE BENEFIT PLANS

Stock Options

     During 1997, the Company adopted a stock option plan (the "Plan") which
provides for the grant of stock options to directors, key employees, and
consultants. As of June 30, 1999, a total of 14,457,000 shares of common stock
are reserved for issuance under the Plan. The Plan provides for the granting of
incentive stock options to employees and nonqualified options to employees,
directors and consultants.

     Stock options are granted with an exercise price not less than fair market
value of the common stock on the date of the grant, as determined by the board
of directors. The vesting period is determined by the board of directors and is
generally four years. The options generally expire ten years after the date of
grant. During February 1998, the board of directors reduced the exercise price
of 140,260 options from $0.28 to $0.05 and in July 1998, they reduced the
exercise price for 18,500 options from $0.05 to $0.03.

     The Company records compensation expense related to stock options granted
to employees using the intrinsic value based method and includes a pro forma
disclosure in the footnotes for compensation value measured using the fair value
accounting treatment. Options granted to consultants are accounted for based on
the fair value of the consideration received or the fair value of the options
issued, whichever is more reliably measurable. For the fair value disclosure
below, compensation value is estimated for each option grant under the Plan on
the date of grant using a Black-Scholes-type option pricing model. The following
assumptions were used for grants in 1997 and the 1998: risk-free rates
corresponding to government securities with original maturities similar to the
expected option lives of 6.3% to 6.8% in 1997, 4.5% to 5.6% for 1998, and 4.9%
to 5.4% for the six months ended June 30, 1999; expected dividend yield of 0%
for all periods; volatility factor of zero; and expected lives of approximately
one year beyond vesting dates for all periods.

     Based on calculations using a Black-Scholes-type minimum value option
pricing model, the weighted-average grant date fair value of options was $0.08,
$0.01 and $0.01 in 1997 1998, and for the six months ended June 30, 1999,
respectively. The pro forma impact on the Company's net loss and net

401(k) Plan

     The Company has adopted an employee savings and retirement plan (the
"401(k) Plan") covering substantially all of the Company's employees. Pursuant
to the 401(k) Plan, eligible employees may elect to reduce their current
compensation by up to the statutory prescribed limit and have the amount of such
reduction contributed to the 401(k) Plan. The Company may make contributions to
the 401(k) Plan on behalf of eligible employees. The Company has not made any
contributions to the 401(k) Plan.

7.  INCOME TAXES

     Prior to January 1, 1996, the Company elected to be taxed under Subchapter
S of the Internal Revenue Code of 1986, as amended (the "Code"). Accordingly the
stockholders were responsible for payment of taxes on income earned by the
Company, and the Company distributed to stockholders annually an amount equal to
the estimated tax liability arising from operations. On January 1, 1996, the
Company revoked its election to be taxed under Subchapter S of the Code and
elected to be taxed under Subchapter C of the Code. In connection with the
change in status, the Company reclassified accumulated earnings of $576,000 to
additional paid-in capital to reduce accumulated earnings to zero as of the date
of the conversion. At December 31, 1998, the Company had net operating loss
("NOL") carryforwards of approximately $9.4 million which may be used to offset
future taxable income. These carryforwards expire beginning in 2011. The Tax
Reform Act of 1986 contains provisions that may limit the NOL available for use
in any given year upon the occurrence of certain events, including significant
changes in ownership interest. A change in ownership of a company of greater
than 50% within a three-year period results in an annual limitation on the
Company's ability to utilize its NOL carryforwards from tax periods prior to the
ownership change. The Company believes that its recent private placements of
mandatorily redeemable Convertible Preferred Stock and/or its initial public
offering of common stock may result in a change of ownership that could
substantially limit its ability to realize its net operating loss carryforwards
in future periods.

     The Company's NOLs represent unrecognized tax benefit. Recognition of these
benefits requires future taxable income, the attainment of which is uncertain.
Therefore, a valuation allowance has been established for the entire tax
benefit, and no benefit for income taxes has been recognized in the accompanying
statements of operations.

     The benefit for income taxes differs from the amount computed by applying
the U.S. federal income tax rate of 34% to loss before income taxes as follows

</TABLE>

     Total rent expense for the years ended December 31, 1996, 1997 and 1998 was
approximately $288,000, $356,000 and $438,000, respectively.

     In December 1998, the Company purchased an exclusive license for certain
software to be resold. This arrangement requires the Company to pay a royalty of
17.5% of all of its sales of the software. In the event the Company does not
satisfy specified minimum sales levels through June 30, 2000, the Company may
forfeit the exclusive rights to resell this software.

     The Company has entered into another arrangement with a customer that
provides for a 10% royalty payment to the customer in the event the Company
resells the proprietary module developed for this customer.

9.  SUBSEQUENT EVENTS

     In July 1999, the board of directors amended all existing stock option
agreements under the Plan. The amendment provided that all options are
immediately exercisable. However, any shares acquired upon exercise are subject
to repurchase by XCare.net over a reverse vesting period that entitles the
optionee to exactly the same vesting schedule as the original grant. The
repurchase price is equal to the exercise price of the options.

     Subsequent to June 30, 1999, the Company issued stock options to certain
employees under the Plan with exercise prices below the deemed fair value of the
Company's common stock at the date of grant. The Company will record deferred
stock compensation for the difference between the exercise price of the stock
options and the deemed fair value of the Company's common stock at the date of
grant. This deferred stock compensation will be amortized to expense over the
period during which the options or common stock subject to repurchase vest,
generally four years, using an accelerated method as described in Financial
Accounting Standards Board Interpretation No. 28.

     In October 1999, the board of directors adopted an employee stock purchase
plan (the "Employee Stock Purchase Plan,") subject to shareholder approval which
will become effective immediately on the effective date of the IPO. A total of
3,500,000 shares of common stock have been reserved for issuance under the
Employee Stock Purchase Plan. The Employee Stock Purchase Plan permits eligible
employees to purchase common stock totaling up to 15% of an employee's
compensation through payroll deductions. The Employee Stock Purchase Plan for
U.S. employees is intended to qualify under Section 423 of the Internal Revenue
Code and contains consecutive overlapping twelve month offering periods. Each
offering period includes 2 six month purchase periods. The price of common stock
to be purchased will be 85% of the lower of the fair market value of the common
stock either at the beginning of the offering period or at the end of that
purchase period.

                 NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)

     In September 1999, the board of directors increased the number of shares
reserved for issuance under the Plan to 22,000,000.

     In October 1999, the board of directors adopted the Director Option Plan,
subject to shareholder approval, which will become effective immediately on the
effective date of the IPO. A total of 1,750,000 shares of common stock have been
reserved for issuance under the Director Option Plan. Members of the board of
directors who are not employees of XCare.net are eligible to participate in the
Director Option Plan. The Director Option Plan provides for an automatic initial
grant of an option to purchase 175,000 shares of common stock (the "Initial
Grant") upon the later of the effective date of the Director Option Plan or the
date a person first becomes a non-employee director. After the Initial Grant, a
non-employee director will automatically be granted options to purchase 70,000
shares of common stock ("Subsequent Grant") each year on the date of XCare.net's
annual stockholder's meeting, if such director has served as a member of the
board for at least six months. The term of such options is ten years, provided
that they will terminate three months following the date the director ceases to
be a director of XCare.net or twelve months if the termination is due to death
or disability. Each Initial Grant will vest as to 25% of the shares on each
anniversary date of the date of grant and each Subsequent Grant will vest as to
100% of the shares on the anniversary date of the date of grant.

     In October 1999, the board of directors approved an amendment to the
Company's certificate of incorporation, subject to shareholder approval,
whereby, after the IPO, the board of directors will have the authority, without
further action by the stockholders, to issue up to 5,000,000 shares of preferred
stock in one or more series and to fix the designations, powers, preferences,
privileges, which may be greater than the rights of the common stock.

     Script: (Lorine Sweeney) (see "Business--Overview--Health Care Market
Overview"): The U.S. Health Care Finance Administration estimates that health
care expenditures currently represent $1.2 trillion, or 14% of the U.S. economy,
and that these expenditures will increase to $2.0 trillion by 2007 due both to
rising health care costs and an aging population. Health care claims, which
totaled approximately 4.4 billion in 1998, generally are processed through
antiquated legacy systems via paper, fax or phone. These systems can be
inefficient and lead to unnecessary and duplicative costs.

     Visual Text:  Title: Health Care: Industry Participants.

     Script:  (Lorine Sweeney) (see "Business -- Overview -- Health Care Market
Overview"): The health care industry is currently one of the most complex
markets due to the numerous interrelationships among health care participants.
The payment for and delivery of health care requires that consistent, accurate
information be shared confidentially among health care participants across a
large and fragmented industry. For instance, individuals compare medical plans,
choose physicians and submit claims for reimbursement. Physicians, hospitals and
other providers verify patient eligibility, collect patient histories, order
diagnostic tests and x-rays, render diagnoses and submit claims to payers. And
payers manage referrals, establish medical care protocols and reimbursement
policies and process claims. These health care transactions are all highly
dependent on the collection and communication of information, and each
participant is dependent on the others for portions of that information.

     Script:  (Lorine Sweeney) (see "Business -- Overview -- Market
Characteristics"): The health care market is highly fragmented. Because health
care is delivered locally, there are hundreds of thousands of market
participants in different locations. Current technology infrastructure in health
care is characterized by numerous incompatible and, in many cases, antiquated
legacy systems.

     Visual Text:  Title: Health Care: Market Characteristics and Issues. Within
the "Market Fragmentation" box, bullets will read:

        - Geographic fragmentation

        - Technological fragmentation

      Within the "Complex Processes" box, bullets will read:

        - Transition to managed care

        - Intensive data management

        - No standard data format or business rules

        - Complexity of procurement, purchasing and payment processes

        - Increasing government regulation

      Within the "Inefficiencies" box, bullets will read:

        - Inability to manage and exchange data

        - Lack of real time and secure communication

        - Rising costs

     Script:  (Lorine Sweeney) (see "Business -- Overview -- Current Health Care
Market Issues" and "-- Health Care Market Overview"): As a result of the
fragmentation and complexity of the health care market, participants are unable
to cost-effectively manage, communicate and exchange information in real time.
This fragmentation and complexity has resulted in increasing dissatisfaction
among health care participants. We believe that providing new, Internet-based,
business-to-business connectivity, information exchange and electronic commerce
solutions that effectively address processing inefficiencies is one of the
largest market opportunities in health care today.

     Visual Text:  Title: XCare.net Solution.

     Script:  (Lorine Sweeney) (see "Business -- Our Solution"): We have
developed an Internet-based, information and transaction technology platform,
which we call the XCare.net platform. Using the XCare.net platform, we connect
health care participants together into a community structure and deliver
applications, services and electronic commerce product offerings that are
designed to improve process efficiencies, reduce administrative costs and create
new revenue opportunities for our customers. We believe that the XCare.net
platform and our solutions can reduce administrative and transaction
inefficiencies and simplify the way business is conducted in health care. We
believe that our solutions have the following advantages:

     Script:  (Lorine Sweeney) (see "Business -- Our Solution"): The XCare.net
platform and associated applications and services are based on the extensible
mark-up language, or XML. XML provides a rich document structure that allows
complex data from multiple sources to be dynamically processed and displayed to
users in personalized ways. We believe that these capabilities are particularly
applicable to the health care industry because XML can process data previously
trapped in legacy systems, allow for automation of health care processes and
integrate a wide array of health care data including audio, video and text.

     Script:  (Lorine Sweeney) (see "Business -- Our Solution"): Our business
model is based on a multi-faceted network of collaborative relationships, which
we call Solution Channels. Our Solution Channels leverage our customers' and
vendors' core competencies to promote the exchange of health care related
services and products. XCare.net Solution Channels create a community which
enables our customers to also act as vendors of applications, services and
products to other XCare.net community participants. Solution Channels allow us
to create new revenue opportunities for others; identify new

        - Cross-sell applications, services and electronic commerce product
          offerings in our Solution Channels

     Script: (Lorine Sweeney) (see "Business -- Strategy"): Our strategy to grow
the Company focuses on the following initiatives. First, we believe that our
Solution Channels represent an opportunity for deploying new applications,
services and electronic commerce product offerings that are either internally
developed or obtained through our growing number of customer and vendor
relationships. We believe this cross-selling approach simplifies the sales
process and may shorten our sales cycle and reduce our cost of sales.

     Script: (Lorine Sweeney) (see "Business -- Strategy"): We estimate that
there are approximately 12,000 entities operating within the payer/third-party
administrator and at-risk provider market segments. We believe that these
organizations have both the funding to adopt new Internet-based process
improvements and the incentive to lower ongoing operating costs in order to
improve their margins.

pursuing strategic relationships with leaders in key health care industry
segments to increase our portfolio of applications, services and product
offerings, to increase the scope of the community of users and to provide
specialized industry expertise for new solutions. We believe this will result in
accelerated market awareness and demand for our applications, services and

of the prospectus.

     Visual Text:  Title: Technology

     Script:  (Lorine Sweeney) (see "Business -- Technology"): We believe that
the XCare.net platform is the first XML-based infrastructure using the Topic
Navigation Mapping standard that is specifically tailored to meet the demands of
health care industry participants. Unlike the current Internet standard,
hypertext mark-up language, or HTML, XML in combination with Topic Navigation
Mapping allows a higher degree of flexibility for customized data exchange
between health care participants. We expect XML to be a predominant protocol for
exchanging multimedia data for information exchange and electronic commerce in
the future. Topic Navigation Mapping provides a standard format for indexing and
structuring the XML formatted content. We call the resulting indices and
structures Topic Maps. We take advantage of the benefits of both XML and Topic
Navigation Mapping technologies to process data previously trapped in legacy
systems, allow for automation of health care processes and integrate a wide
variety of health care data including audio, video and text. We use a set form
of software applications,

                                       A-7

known as brokering components, to find, integrate and present relevant,
customized information to individual users. Let's walk through the diagram to
see how this technology actually works. In step one, a user initiates a request
for information. In step two, the Context Broker describes the user's request
and passes it to the Semantic Broker. In step three, the Semantic Broker queries
the Logic Fabric for the transaction that will satisfy the request. In step
four, the Semantic Broker dispatches the Service Broker to obtain information
from the Internet. In step five, information is returned to the Context Broker,
which presents the information in a customized view for users.

table.

     Script:  (Peter Cheesbrough) (See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Overview" and "-- Quarterly
Results of Operations"):

      We commenced operations in March 1989, but we did not begin to focus on
Internet-based health care solutions until mid-1998. We have historically
derived a significant portion of revenue from sales of mainframe and
client-server software for managed health care systems and from providing
services to health care organizations seeking to outsource administrative
functions. We intend to derive an increasing portion of our future revenue from
our Internet-based applications, services and product offerings. Accordingly, we
believe that our historical financial results are not necessarily indicative of
our future financial performance.

     We have experienced quarterly fluctuations in our operating and financial
results due to the timing and relative size of new custom software development
projects, cancellations of contracts, and fluctuations in costs, including
personnel, equipment and facilities costs. We expect quarterly results to
fluctuate in the future due to the timing and introduction of new applications
and services and other market factors.

     The following table sets forth unaudited statement of operations data for
each of the six quarters ended June 30, 1999. This information has been derived
from our unaudited financial statements. These unaudited quarterly results
should be read in conjunction with the financial statements and notes thereto
appearing elsewhere in the prospectus.

     Revenue increased significantly during the quarter ended March 31, 1999 due
to the progress made in completing several custom software development projects.
Revenue for the quarter ended June 30, 1999 decreased relative to the prior
quarter as limited working capital available during the six months ended June
30, 1999 resulted in a reduction in our sales force personnel and other
promotional marketing activities, which impeded our ability to generate new
sales leads.

     Cost of revenue as a percentage of revenue has varied from quarter to
quarter due to fluctuations in quarterly revenue and changes in associated
personnel costs. During the quarter ended March 31, 1999, cost of revenue
decreased as a percentage of revenue due to increased revenue from the
completion of several custom software development projects during the quarter.
During the quarter ended June 30, 1999, the increase in cost of revenue as a
percentage of revenue reflects the decreased revenue recognized during the
quarter, the amortization of purchased software and the transfer of certain
personnel from research and development to custom software development projects.

     During the quarter ended December 31, 1998, general and administrative
expense increased in absolute dollars and as a percentage of revenue due to an
approximate $360,000 loss on disposal of fixed assets. During the quarter ended
March 31, 1999, sales and marketing and general administrative expense declined
in both dollars and as a percentage of revenue due to substantial reductions of
personnel costs.

     Research and development expenses sharply declined following the quarter
ended March 31, 1998 due to reduction of research and development personnel
caused by limited working capital.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     As permitted by Section 145 of the Delaware General Corporation Law, the
registrant's certificate of incorporation includes a provision that eliminates
the personal liability of its directors for monetary damages for breach or
alleged breach of their duty of care. In addition, as permitted by Section 145
of the Delaware General Corporation Law, the bylaws of the registrant provide
that: (1) the registrant is required to indemnify its directors and executive
officers and persons serving in such capacities in other business enterprises
(including, for example, subsidiaries of the registrant) at the registrant's
request, to the fullest extent permitted by Delaware law, including in those
circumstances in which indemnification would otherwise be discretionary; (2) the
registrant may, in its discretion, indemnify employees and agents in those
circumstances where indemnification is not required by law; (3) the registrant
is required to advance expenses, as incurred, to its directors and executive
officers in connection with defending a proceeding (except that it is not
required to advance expenses to a person against whom the registrant brings a
claim for breach of the duty of loyalty, failure to act in good faith,
intentional misconduct, knowing violation of law or deriving an improper
personal benefit; (4) the rights conferred in the bylaws are not exclusive, and
the registrant is authorized to enter into indemnification agreements with its
directors, executive officers and employees; and (5) the registrant may not
retroactively amend the bylaw provisions in a way that it adverse to such
directors, executive officers and employees.

     The registrant's policy is to enter into indemnification agreements with
each of its directors and executive officers that provide the maximum indemnity
allowed to directors and executive officers by Section 145 of the Delaware
General Corporation Law and the bylaws, as well as certain additional procedural
protections. In addition, such indemnity agreements provide that directors and
executive officers will be indemnified to the fullest possible extent not
prohibited by law against all expenses (including attorney's fees) and
settlement amounts paid or incurred by them in any action or proceeding,
including any derivative action by or in the right of the registrant, on account
of their services as directors or executive officers of the registrant or as
directors or officers of any other company or enterprise when they are serving
in such capacities at the request of the registrant. The registrant will not be
obligated pursuant to the indemnity agreements to indemnify or advance expenses
to an indemnified party with respect to proceedings or claims initiated by the
indemnified party and not by

                                      II-1
<PAGE>   112

way of defense, except with respect to proceedings specifically authorized by
the registrant's board of directors or brought to enforce a right to
indemnification under the indemnity agreement, the registrant's bylaws or any
statute or law. Under the agreements, the registrant is not obligated to
indemnify the indemnified party (1) for any expenses incurred by the indemnified
party with respect to any proceeding instituted by the indemnified party to
enforce or interpret the agreement, if a court of competent jurisdiction
determines that each of the material assertions made by the indemnified party in
such proceeding was not made in good faith or was frivolous; (2) for any amounts
paid in settlement of a proceeding unless the registrant consents to such
settlement; (3) with respect to any proceeding brought by the registrant against
the indemnified party for willful misconduct, unless a court determines that
each of such claims was not made in good faith or was frivolous; (4) on account
of any suit in which judgment is rendered against the indemnified party for an
accounting of profits made from the purchase or sale by the indemnified party of
securities of the registrant pursuant to the provisions of sec. 16(b) of the
Securities Exchange Act of 1934 and related laws; (5) on account of the
indemnified party's conduct which is finally adjudged to have been knowingly
fraudulent or deliberately dishonest, or to constitute willful misconduct or a
knowing violation of the law; (6) an account of any conduct from which the
indemnified party derived an improper personal benefit; (7) on account of
conduct the indemnified party believed to be contrary to the best interests of
the registrant or its stockholders; (8) on account of conduct that constituted a
breach of the indemnified party's duty of loyalty to the registrant or its
stockholders; or (9) if a final decision by a court having jurisdiction in the
matter shall determine that such indemnification is not lawful.

     The indemnification provision in the bylaws and the indemnification
agreements entered into between the registrant and its directors and executive
officers, may be sufficiently broad to permit indemnification of the
registrant's officers and directors for liabilities arising under the 1933 Act.

     Reference is made to the following documents filed as exhibits to this
registration statement regarding relevant indemnification provisions described
above and elsewhere herein:

     Schedules not listed above have been omitted because the information
required to be set forth therein is not applicable or is shown in the financial
statements or notes thereto.

ITEM 17.  UNDERTAKINGS

     The undersigned hereby undertakes to provide to the Underwriters at the
closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

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

     The undersigned registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Act, 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 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 Act, 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.

<PAGE>   5

        2.3     SPECIAL MEETING

        Except as otherwise required by law, a special meeting of the
stockholders may be called only by the Board of Directors, the Chairman of the
Board, or the President; provided however, that if at any time no directors
remain in office, then a special meeting for the purpose of electing directors
may be called in accordance with the procedure set forth in the Bylaws. No
business may be transacted at such special meeting otherwise than as specified
in the notice of such meeting.

        2.4     NOTICE OF STOCKHOLDERS' MEETINGS

        All notices of meetings of stockholders shall be sent or otherwise given
in accordance with Section 2.6 of these bylaws not less than ten (10) nor more
than sixty (60) days before the date of the meeting. The notice shall specify
the place, date and hour of the meeting and (i) in the case of a special
meeting, the purpose or purposes for which the meeting is called (no business
other than that specified in the notice may be transacted) or (ii) in the case
of the annual meeting, those matters which the board of directors, at the time
of giving the notice, intends to present for action by the stockholders (but any
proper matter may be presented at the meeting for such action). The notice of
any meeting at which directors are to be elected shall include the name of any
nominee or nominees who, at the time of the notice, the board intends to present
for election.

        2.5     ADVANCE NOTICE OF STOCKHOLDER NOMINEES AND STOCKHOLDER BUSINESS

        Subject to the rights of holders of any class or series of stock having
a preference over the Common Stock as to dividends or upon liquidation,

                (a)     nominations for the election of directors, and

                (b)     business proposed to be brought before any stockholder
                        meeting

may be made by the board of directors or proxy committee appointed by the board
of directors or by any stockholder entitled to vote in the election of directors
generally if such nomination or business proposed is otherwise proper business
before such meeting. However, any such stockholder may nominate one or more
persons for election as directors at a meeting or propose business to be brought
before a meeting, or both, only if such stockholder has given timely notice to
the secretary of the corporation in proper written form of their intent to make
such nomination or nominations or to propose such business. To be timely, such
stockholder's notice must be delivered to or mailed and received at the
principal executive offices of the corporation not less than one hundred twenty
(120) calendar days in advance of the date of the corporation's proxy statement
released to stockholders in connection with the previous year's annual meeting
of stockholders; provided, however, that in the event that no annual meeting was
held in the previous year or the date of the annual meeting has been changed by
more than thirty (30) days from the date contemplated at the time of the
previous year's proxy statement, notice by the stockholder to be timely must be
so received a reasonable time before the solicitation is made. To be in proper
form, a stockholder's notice to the secretary shall set forth:

                                      -2-
<PAGE>   6

                        (i)     the name and address of the stockholder who
intends to make the nominations or propose the business and, as the case may be,
of the person or persons to be nominated or of the business to be proposed;

                        (ii)    a representation that the stockholder is a
holder of record of stock of the corporation entitled to vote at such meeting
and, if applicable, intends to appear in person or by proxy at the meeting to
nominate the person or persons specified in the notice;

                        (iii)   if applicable, a description of all arrangements
or understandings between the stockholder and each nominee and any other person
or persons (naming such person or persons) pursuant to which the nomination or
nominations are to be made by the stockholder;

                        (iv)    such other information regarding each nominee or
each matter of business to be proposed by such stockholder as would be required
to be included in a proxy statement filed pursuant to the proxy rules of the
Securities and Exchange Commission had the nominee been nominated, or intended
to be nominated, or the matter been proposed, or intended to be proposed by the
board of directors; and

                        (v)     if applicable, the consent of each nominee to
serve as director of the corporation if so elected.

        The chairman of the meeting shall refuse to acknowledge the nomination
of any person or the proposal of any business not made in compliance with the
foregoing procedure.

        2.6     MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

        Written notice of any meeting of stockholders shall be given either
personally or by first-class mail or by telegraphic or other written
communication. Notices not personally delivered shall be sent charges prepaid
and shall be addressed to the stockholder at the address of that stockholder
appearing on the books of the corporation or given by the stockholder to the
corporation for the purpose of notice. Notice shall be deemed to have been given
at the time when delivered personally or deposited in the mail or sent by
telegram or other means of written communication.

        An affidavit of the mailing or other means of giving any notice of any
stockholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

        2.7     QUORUM

        The holders of a majority in voting power of the stock issued and
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise provided by statute or by the
certificate of incorporation. If, however, such quorum is not present or
represented at any meeting of the stockholders, then either (i) the chairman of
the meeting or (ii) the stockholders entitled to


                                      -3-
<PAGE>   7

vote thereat, present in person or represented by proxy, shall have power to
adjourn the meeting in accordance with Section 2.7 of these bylaws.

        When a quorum is present at any meeting, the vote of the holders of a
majority of the stock having voting power present in person or represented by
proxy shall decide any question brought before such meeting, unless the question
is one upon which, by express provision of the laws of the State of Delaware or
of the certificate of incorporation or these bylaws, a different vote is
required, in which case such express provision shall govern and control the
decision of the question.

        If a quorum be initially present, the stockholders may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken is approved by a
majority of the stockholders initially constituting the quorum.

        2.8     ADJOURNED MEETING; NOTICE

        When a meeting is adjourned to another time and place, unless these
bylaws otherwise require, notice need not be given of the adjourned meeting if
the time and place thereof are announced at the meeting at which the adjournment
is taken. At the adjourned meeting the corporation may transact any business
that might have been transacted at the original meeting. If the adjournment is
for more than thirty (30) 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.

        2.9     VOTING

        The stockholders entitled to vote at any meeting of stockholders shall
be determined in accordance with the provisions of Section 2.11 of these bylaws,
subject to the provisions of Sections 217 and 218 of the General Corporation Law
of Delaware (relating to voting rights of fiduciaries, pledgors and joint
owners, and to voting trusts and other voting agreements).

        Except as may be otherwise provided in the certificate of incorporation
or these bylaws, each stockholder shall be entitled to one vote for each share
of capital stock held by such stockholder with respect to any matter submitted
to a vote of the stockholders and stockholders shall not be entitled to cumulate
their votes in the election of directors.

        2.10    WAIVER OF NOTICE

        Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or
these bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice. Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or

                                      -4-
<PAGE>   8

special meeting of the stockholders need be specified in any written waiver of
notice unless so required by the certificate of incorporation or these bylaws.

        2.11    RECORD DATE FOR STOCKHOLDER NOTICE; VOTING

        For purposes of determining the stockholders entitled to notice of any
meeting or to vote thereat, the board of directors may fix, in advance, a record
date, which shall not precede the date upon which the resolution fixing the
record date is adopted by the board of directors and which shall not be more
than sixty (60) days nor less than ten (10) days before the date of any such
meeting, and in such event only stockholders of record on the date so fixed are
entitled to notice and to vote, notwithstanding any transfer of any shares on
the books of the corporation after the record date.

        If the board of directors does not so fix a record date, the record date
for determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business on the business day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the business day next preceding the day on which the
meeting is held.

        A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting
unless the board of directors fixes a new record date for the adjourned meeting,
but the board of directors shall fix a new record date if the meeting is
adjourned for more than thirty (30) days from the date set for the original
meeting.

        The record date for any other purpose shall be as provided in Section
8.1 of these bylaws.

        2.12    PROXIES

        Every person entitled to vote for directors, or on any other matter,
shall have the right to do so either in person or by one or more agents
authorized by a written proxy signed by the person and filed with the secretary
of the corporation, but no such proxy shall be voted or acted upon after three
(3) years from its date unless the proxy provides for a longer period. A proxy
shall be deemed signed if the stockholder's name is placed on the proxy (whether
by manual signature, typewriting, telegraphic transmission, telefacsimile or
otherwise) by the stockholder or the stockholder's attorney-in-fact. The
revocability of a proxy that states on its face that it is irrevocable shall be
governed by the provisions of Section 212(e) of the General Corporation Law of
Delaware.

        2.13    ORGANIZATION

        The president, or in the absence of the president, the chairman of the
board, or, in the absence of the president and the chairman of the board, one of
the corporation's vice presidents, shall call the meeting of the stockholders to
order, and shall act as chairman of the meeting. In the absence of the
president, the chairman of the board, and all of the vice presidents, the
stockholders shall appoint a chairman for such meeting. The chairman of any
meeting of stockholders shall determine the order of business and the procedures
at the meeting, including such matters as the regulation of the manner of voting
and the conduct of business. The secretary of the corporation shall act as
secretary of all


                                      -5-
<PAGE>   9

meetings of the stockholders, but in the absence of the secretary at any meeting
of the stockholders, the chairman of the meeting may appoint any person to act
as secretary of the meeting.

        2.14    LIST OF STOCKHOLDERS ENTITLED TO VOTE

        The officer who has charge of the stock ledger of the corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, 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. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

        3.2     NUMBER OF DIRECTORS

        The board of directors shall consist of nine members. The board of
directors may increase or decrease the number of directors constituting the
board of directors upon the approval of a majority of the directors then in

directors of the corporation. No reduction of the authorized number of directors
shall have the effect of removing any director before that director's term of
office expires.

        3.3     ELECTION AND TERM OF OFFICE OF DIRECTORS

        Except as provided in Section 3.4 of these bylaws, directors shall be

        3.4     RESIGNATION AND VACANCIES

        Any director may resign effective on giving written notice to the
chairman of the board, the president, the secretary or the board of directors,
unless the notice specifies a later time for that resignation to become
effective. If the resignation of a director is effective at a future time, the
board of directors may elect a successor to take office when the resignation
becomes effective.

         All vacancies in the board of directors may be filled by a majority of
the remaining directors, even if less than a quorum, or by a sole remaining
director; provided, that whenever the holders of any class or classes of stock
or series thereof are entitled to elect one or more directors by the provisions
of the certificate of incorporation, vacancies and newly created directorships
of such class or classes or series may be filled by a majority of the directors
elected by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

        3.5     PLACE OF MEETINGS; MEETINGS BY TELEPHONE

        Regular meetings of the board of directors may be held at any place
within or outside the State of Delaware that has been designated from time to

Special meetings of the board may be held at any place within or outside the
State of Delaware that has been designated in the notice of the meeting or, if

        Any meeting, regular or special, may be held by conference telephone or
similar communication equipment, so long as all directors participating in the
meeting can hear one another; and all such directors shall be deemed to be
present in person at the meeting.

        3.6     REGULAR MEETINGS

        Regular meetings of the board of directors may be held without notice if
the times of such meetings are fixed by the board of directors. If any regular
meeting day shall fall on a legal holiday, then the meeting shall be held next
succeeding full business day.

        3.7     SPECIAL MEETINGS; NOTICE

        Special meetings of the board of directors for any purpose or purposes
may be called at any time by the chairman of the board, the president, any vice

personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's address
as it is shown on the records of the corporation. If the notice is mailed, it
shall be deposited in the United States mail at least four (4) days before the
time of the holding of the meeting. If the notice is delivered personally or by
telephone or telegram, it shall be delivered personally or by telephone or to
the telegraph company at least forty-eight (48) hours before the time

                                      -7-
<PAGE>   11

of the holding of the meeting. Any oral notice given personally or by telephone
may be communicated either to the director or to a person at the office of the
director who the person giving the notice has reason to believe will promptly
communicate it to the director. The notice need not specify the purpose or the
place of the meeting, if the meeting is to be held at the principal executive
office of the corporation.

        3.8     QUORUM

        A majority of the authorized number of directors shall constitute a
quorum for the transaction of business, except to adjourn as provided in Section
3.10 of these bylaws. Every act or decision done or made by a majority of the
directors present at a duly held meeting at which a quorum is present shall be
regarded as the act of the board of directors, subject to the provisions of the
certificate of incorporation and other applicable law.

        A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

        3.9     WAIVER OF NOTICE

        Notice of a meeting need not be given to any director (i) who signs a
waiver of notice or a consent to holding the meeting or an approval of the
minutes thereof, whether before or after the meeting, or (ii) who attends the
meeting without protesting, prior thereto or at its commencement, the lack of
notice to such directors. All such waivers, consents, and approvals shall be
filed with the corporate records or made part of the minutes of the meeting. A
waiver of notice need not specify the purpose of any regular or special meeting
of the board of directors.

        3.10    ADJOURNMENT

        A majority of the directors present, whether or not constituting a
quorum, may adjourn any meeting to another time and place.

        3.11    NOTICE OF ADJOURNMENT

        Notice of the time and place of holding an adjourned meeting need not be
given unless the meeting is adjourned for more than twenty-four (24) hours. If
the meeting is adjourned for more than twenty-four (24) hours, then notice of
the time and place of the adjourned meeting shall be given before the adjourned
meeting takes place, in the manner specified in Section 3.7 of these bylaws, to
the directors who were not present at the time of the adjournment.

        3.12    BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

        Any action required or permitted to be taken by the board of directors
may be taken without a meeting, provided that all members of the board
individually or collectively consent in writing to that action. Such action by
written consent shall have the same force and effect as a unanimous vote

                                      -8-
<PAGE>   12

of the board of directors. Such written consent and any counterparts thereof
shall be filed with the minutes of the proceedings of the board.

        Directors and members of committees may receive such compensation, if
any, for their services and such reimbursement of expenses as may be fixed or
determined by resolution of the board of directors. This Section 3.13 shall not
be construed to preclude any director from serving the corporation in any other
capacity as an officer, agent, employee or otherwise and receiving compensation
for those services.

        3.14    APPROVAL OF LOANS TO OFFICERS

        The corporation may lend money to, or guarantee any obligation of, or
otherwise assist any officer or other employee of the corporation or any of its
subsidiaries, including any officer or employee who is a director of the
corporation or any of its subsidiaries, whenever, in the judgment of the
directors, such loan, guaranty or assistance may reasonably be expected to
benefit the corporation. The loan, guaranty or other assistance may be with or
without interest and may be unsecured, or secured in such manner as the board of
directors shall approve, including, without limitation, a pledge of shares of
stock of the corporation. Nothing contained in this Section shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.


                                   ARTICLE IV

                                   COMMITTEES

        4.1     COMMITTEES OF DIRECTORS

        The board of directors may, by resolution adopted by a majority of the
authorized number of directors, designate one (1) or more committees, each
consisting of two or more directors, to serve at the pleasure of the board. The
board may designate one (1) or more directors as alternate members of any
committee, who may replace any absent member at any meeting of the committee.
The appointment of members or alternate members of a committee requires the vote
of a majority of the authorized number of directors. Any committee, to the
extent provided in the resolution of the board, shall have and may exercise all
the powers and authority of the board, but no such committee shall have the
power of authority to:

                (a)     amend the certificate of incorporation (except that a
committee may, to the extent authorized in the resolution or resolutions
providing for the issuance of shares of stock adopted by the board of directors
as provided in Section 151(a) of the General Corporation Law of Delaware, fix
the designations and any of the preferences or rights of such shares relating to
dividends, redemption, dissolution, any distribution of assets of the
corporation or the conversion

                                      -9-

into, or the exchange of such shares for, shares of any other class or classes
or any other series of the same or any other class or classes of stock of the
corporation);

                (b)     adopt an agreement of merger or consolidation under
Sections 251 or 252 of the General Corporation Law of Delaware;

                (c)     recommend to the stockholders the sale, lease or
exchange of all or substantially all of the corporation's property and assets;

                (d)     recommend to the stockholders a dissolution of the
corporation or a revocation of a dissolution; or

                (e)     amend the bylaws of the corporation; and, unless the
board resolution establishing the committee, the bylaws or the certificate of
incorporation expressly so provide, no such committee shall have the power or

                                   ARTICLE VI

               INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES,
                                AND OTHER AGENTS

        6.1     INDEMNIFICATION OF DIRECTORS AND OFFICERS

        The corporation shall, to the maximum extent and in the manner permitted
by the General Corporation Law of Delaware as the same now exists or may
hereafter be amended, indemnify any person against expenses (including
attorneys' fees), judgments, fines, and amounts paid in settlement actually and
reasonably incurred in connection with any threatened, pending or completed
action, suit, or proceeding in which such person was or is a party or is
threatened to be made a party by reason of the fact that such person is or was a
director or officer of the corporation. For purposes of this Section 6.1, a
"director" or "officer" of the corporation shall mean any person (i) who is or
was a director or officer of the corporation, (ii) who is or was serving at the
request of the corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was a
director or officer of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

        The corporation shall be required to indemnify a director or officer in
connection with an action, suit, or proceeding (or part thereof) initiated by
such director or officer only if the initiation of such action, suit, or
proceeding (or part thereof) by the director or officer was authorized by the
Board of Directors of the corporation.

                                      -13-
<PAGE>   17

        The corporation shall pay the expenses (including attorney's fees)
incurred by a director or officer of the corporation entitled to indemnification
hereunder in defending any action, suit or proceeding referred to in this
Section 6.1 in advance of its final disposition; provided, however, that payment
of expenses incurred by a director or officer of the corporation in advance of
the final disposition of such action, suit or proceeding shall be made only upon
receipt of an undertaking by the director or officer to repay all amounts
advanced if it should ultimately be determined that the director of officer is
not entitled to be indemnified under this Section 6.1 or otherwise.

        The rights conferred on any person by this Article shall not be
exclusive of any other rights which such person may have or hereafter acquire
under any statute, provision of the corporation's Certificate of Incorporation,
these bylaws, agreement, vote of the stockholders or disinterested directors or
otherwise.

        Any repeal or modification of the foregoing provisions of this Article
shall not adversely affect any right or protection hereunder of any person in
respect of any act or omission occurring prior to the time of such repeal or
modification.

        6.2     INDEMNIFICATION OF OTHERS

        The corporation shall have the power, to the maximum extent and in the
manner permitted by the General Corporation Law of Delaware as the same now
exists or may hereafter be amended, to indemnify any person (other than
directors and officers) against expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred in
connection with any threatened, pending or completed action, suit, or
proceeding, in which such person was or is a party or is threatened to be made a
party by reason of the fact that such person is or was an employee or agent of
the corporation. For purposes of this Section 6.2, an "employee" or "agent" of
the corporation (other than a director or officer) shall mean any person (i) who
is or was an employee or agent of the corporation, (ii) who is or was serving at
the request of the corporation as an employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was an
employee or agent of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

        6.3     INSURANCE

        The corporation may purchase and maintain insurance on behalf of any
person who 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 any liability asserted against him or her and incurred
by him or her in any such capacity, or arising out of his or her status as such,
whether or not the corporation would have the power to indemnify him or her
against such liability under the provisions of the General Corporation Law of
Delaware.

                               RECORDS AND REPORTS

        7.1     MAINTENANCE AND INSPECTION OF RECORDS

        The corporation shall, either at its principal executive office or at
such place or places as designated by the board of directors, keep a record of
its stockholders listing their names and addresses and the number and class of
shares held by each stockholder, a copy of these bylaws as amended to date,
accounting books and other records of its business and properties.

        Any stockholder of record, in person or by attorney or other agent,
shall, upon written demand under oath stating the purpose thereof, have the
right during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom. A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder. In every
instance where an attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or
such other writing that authorizes the attorney or other agent to so act on
behalf of the stockholder. The demand under oath shall be directed to the
corporation at its registered office in Delaware or at its principal place of
business.

        7.2     INSPECTION BY DIRECTORS

        Any director shall have the right to examine (and to make copies of) the
corporation's stock ledger, a list of its stockholders and its other books and
records for a purpose reasonably related to his or her position as a director.

        7.3     ANNUAL STATEMENT TO STOCKHOLDERS

        The board of directors shall present at each annual meeting, and at any
special meeting of the stockholders when called for by vote of the stockholders,
a full and clear statement of the business and condition of the corporation.

        7.4     REPRESENTATION OF SHARES OF OTHER CORPORATIONS

        The chairman of the board, if any, the president, any vice president,
the chief financial officer, the secretary or any assistant secretary of this
corporation, or any other person authorized by the board of directors or the
president or a vice president, is authorized to vote, represent and exercise on
behalf of this corporation all rights incident to any and all shares of the
stock of any other corporation or corporations standing in the name of this
corporation. The authority herein granted may be exercised either by such person
directly or by any other person authorized to do so by proxy or power of
attorney duly executed by such person having the authority.

        7.5     CERTIFICATION AND INSPECTION OF BYLAWS

        The original or a copy of these bylaws, as amended or otherwise altered
to date, certified by the secretary, shall be kept at the corporation's
principal executive office and shall be open to inspection by the stockholders

                                  ARTICLE VIII

                                 GENERAL MATTERS

        8.1     RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

        For purposes of determining the stockholders entitled to receive payment
of any dividend or other distribution or allotment of any rights or the
stockholders entitled to exercise any rights in respect of any other lawful
action, the board of directors may fix, in advance, a record date, which shall
not be more than sixty (60) days before any such action. In that case, only
stockholders of record at the close of business on the date so fixed are
entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding any transfer of any
shares on the books of the corporation after the record date so fixed, except as
otherwise provided in the General Corporation Law of Delaware.

        If the board of directors does not so fix a record date, then the record
date for determining stockholders for any such purpose shall be at the close of
business on the day on which the board adopts the applicable resolution.

        8.2     CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS

        From time to time, the board of directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment of money, notes or other evidences of indebtedness that are issued in
the name of or payable to the corporation, and only the persons so authorized
shall sign or endorse those instruments.

        8.3     CORPORATE CONTRACTS AND INSTRUMENTS: HOW EXECUTED

        The board of directors, except as otherwise provided in these bylaws,
may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the name of and on behalf of the
corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the board of directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.

<PAGE>   20

        8.4     STOCK CERTIFICATES; TRANSFER; PARTLY PAID SHARES

        The shares of the corporation shall be represented by certificates,
provided that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares. Any such resolution shall not apply to
shares represented by a certificate until such certificate is surrendered to the
corporation. Notwithstanding the adoption of such a resolution by the board of
directors, every holder of stock represented by certificates and, upon request,
every holder of uncertificated shares, shall be entitled to have a certificate
signed by, or in the name of the corporation by, the chairman or vice-chairman
of the board of directors, or the president or vice-president, and by the
treasurer or an assistant treasurer, or the secretary or an assistant secretary
of such corporation representing the number of shares registered in certificate
form. Any or all of the signatures on the certificate may be a facsimile. In
case any officer, transfer agent or registrar who has signed or whose facsimile
signature has been placed upon a certificate has ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the corporation with the same effect as if he or she were such officer,
transfer agent or registrar at the date of issue.

        Certificates for shares shall be of such form and device as the board of
directors may designate and shall state the name of the record holder of the
shares represented thereby; its number; date of issuance; the number of shares
for which it is issued; a summary statement or reference to the powers,
designations, preferences or other special rights of such stock and the
qualifications, limitations or restrictions of such preferences and/or rights,
if any; a statement or summary of liens, if any; a conspicuous notice of
restrictions upon transfer or registration of transfer, if any; a statement as
to any applicable voting trust agreement; if the shares be assessable, or, if
assessments are collectible by personal action, a plain statement of such facts.

        Upon surrender to the secretary or transfer agent of the corporation of
a certificate for shares duly endorsed or accompanied by proper evidence of
succession, assignment or authority to transfer, it shall be the duty of the
corporation to issue a new certificate to the person entitled thereto, cancel
the old certificate and record the transaction upon its books.

        The corporation may issue the whole or any part of its shares as partly
paid and subject to call for the remainder of the consideration to be paid
therefor. Upon the face or back of each stock certificate issued to represent
any such partly paid shares, or upon the books and records of the corporation in
the case of uncertificated partly paid shares, the total amount of the
consideration to be paid therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the corporation shall
declare a dividend upon partly paid shares of the same class, but only upon the
basis of the percentage of the consideration actually paid thereon.

        8.5     SPECIAL DESIGNATION ON CERTIFICATES

        If the corporation is authorized to issue more than one class of stock
or more than one series of any class, then the powers, the designations, the
preferences and the relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on

                                      -17-
<PAGE>   21

the face or back of the certificate that the corporation shall issue to
represent such class or series of stock; provided, however, that, except as
otherwise provided in Section 202 of the General Corporation Law of Delaware, in
lieu of the foregoing requirements there may be set forth on the face or back of
the certificate that the corporation shall issue to represent such class or
series of stock a statement that the corporation will furnish without charge to
each stockholder who so requests the powers, the designations, the preferences
and the relative, participating, optional or other special rights of each class
of stock or series thereof and the qualifications, limitations or restrictions
of such preferences and/or rights.

        8.6     LOST CERTIFICATES

        Except as provided in this Section 8.6, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and canceled at the same time. The board of
directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates on such terms and conditions as the board may require; the board
may require indemnification of the corporation secured by a bond or other
adequate security sufficient to protect the corporation against any claim that
may be made against it, including any expense or liability, on account of the
alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

        8.7     TRANSFER AGENTS AND REGISTRARS

        The board of directors may appoint one or more transfer agents or
transfer clerks, and one or more registrars, each of which shall be an
incorporated bank or trust company -- either domestic or foreign, who shall be
appointed at such times and places as the requirements of the corporation may
necessitate and the board of directors may designate.

        8.8     CONSTRUCTION; DEFINITIONS

        Unless the context requires otherwise, the general provisions, rules of
construction, and definitions in the General Corporation Law of Delaware shall
govern the construction of these bylaws. Without limiting the generality of this
provision, the singular number includes the plural, the plural number includes
the singular, and the term "person" includes both a corporation and a natural
person.

                                   AMENDMENTS

        9.1     AMENDMENTS BY STOCKHOLDERS AND DIRECTORS

        The original or other bylaws of the corporation may be adopted, amended
or repealed by the stockholders entitled to vote or by the board of directors of
the corporation. The fact that such power has been so conferred upon the
directors shall not divest the stockholders of the power, nor limit their power
to adopt, amend or repeal bylaws.

                                      -18-
<PAGE>   22

        Whenever an amendment or new bylaw is adopted, it shall be copied in the
book of bylaws with the original bylaws, in the appropriate place. If any bylaw
is repealed, the fact of repeal with the date of the meeting at which the repeal
was enacted or the filing of the operative written consent(s) shall be stated in
said book.

        9.2     SUPERMAJORITY VOTE

        Notwithstanding anything to the contrary in the bylaws, neither Section
2.3 (special meeting), Section 2.5 (advance notice of stockholder nominees and
stockholder business), nor this Section 9.2 (supermajority vote) of the bylaws
shall be repealed or amended, nor shall any provision inconsistent with the
aforementioned provisions be adopted and added to the bylaws except upon the
affirmative vote of not less than two-thirds of the shares of the corporation
issued and outstanding.

        Amended and Restated Bylaws adopted by the Board of Directors of the
Corporation at New York, New York, this 5th day of October, 1999.

twenty (20) days after receipt of such written notice from the Company;

provided, however, that the Company shall not be obligated to take any action to
effect any such registration, qualification or compliance pursuant to this
Section 2.1:

                                (A) In any particular jurisdiction in which the
Company would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act;

                                (B) Prior to the earlier of (i) six (6) months
after the effective date of the registration statement in respect of the initial
public offering of the Company's securities, or (ii) three years after the date
of this Agreement;

                                (C) During the period starting with the date
sixty (60) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following the effective date of, any
registration statement pertaining to securities of the Company (other than a

employee benefit plan), provided that the Company is actively employing in good
faith all reasonable efforts to cause such registration statement to become

        In addition, the Company shall not be obligated to take any action
requested by Initiating Holders of Series A Preferred to effect such
registration, qualification, or compliance pursuant to this Section 2.1:

                                (D) After the Company has effected two such

Holders of Series A Preferred, and each such registration has been declared or
ordered effective;

                                (E) After the Company has effected one such
registration pursuant to this Section 2.1(a) at the request of Initiating
Holders of Series A Preferred, and such registration has been declared or
ordered effective during the preceding 12 months; or

                                (F) If the Company shall furnish to such Holders
a certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company or its shareholders for a registration statement to be filed in the
near future, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 2.1 shall be deferred for a period not to
exceed one hundred twenty (120) days from the date of receipt of written request
from the Initiating Holders, provided that such right to delay a request may not

        In addition, the Company shall not be obligated to take any action
requested by Initiating Holders of Series B Preferred to effect such
registration, qualification, or compliance pursuant to this Section 2.1:

                                (G) After the Company has effected two such
registrations pursuant to this Section 2.1(a) at the request of Initiating
Holders of Series B Preferred, and each such registration has been declared or
ordered effective;

                                (H) After the Company has effected one such
registration pursuant to this Section 2.1(a) at the request of Initiating
Holders of Series B Preferred, and such registration has been declared or
ordered effective during the preceding 12 months; or

                                (I) If the Company shall furnish to such Holders
a certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company or its shareholders for a registration statement to be filed in the
near future, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 2.1 shall be deferred for a period not to
exceed one hundred twenty (120) days from the date of receipt of written request
from the Initiating Holders, provided that such right to delay a request may not
be exercised by the Company more than once in any twelve-month period.

        Subject to the foregoing clauses (A) through (I), the Company shall file
a registration statement covering the Registrable Securities so requested to be
registered, after receipt of the request or requests of the Initiating Holders.
Any registration pursuant to this Section 2.1 shall not be treated as a request
for registration by the Initial Holders if greater than twenty percent of the
shares of Common Stock requested to be registered are not registered.

                (b) Underwriting. In the event that a registration pursuant to
Section 2.1 is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as part of the notice given pursuant to
Section 2.1(a)(i). In such event, the right of any Holder to registration
pursuant to Section 2.1 shall be conditioned upon such Holder's participation in
the underwriting arrangements required by this Section 2.1(b), and the inclusion
of such Holder's Registrable Securities in the underwriting to the extent
requested shall be limited to the extent provided herein.

        The Company shall (together with all Holders proposing to distribute
their securities through such underwriting) enter into an underwriting agreement
in customary form with the managing underwriter selected for such underwriting
by a majority in interest of the Initiating Holders, but subject to the
Company's reasonable approval. Notwithstanding any other provision of this
Section 2.1, if the managing underwriter advises the Initiating Holders in
writing that marketing factors require a limitation of the number of shares to
be underwritten, then the Company shall so advise all Holders of Registrable
Securities and the number of shares of Registrable Securities to be included in
the registration shall be allocated in the following manner:


                                      -6-
<PAGE>   8

                        (i)first, among all Holders of Registrable Securities of
the same class of Series A or Series B Preferred requested by the Initiating
Holders, on a pro rata basis, as nearly as practicable up to the lesser of the
respective amounts of Registrable Securities held by such Holders at the time of
filing the Registration Statement, or 70% of the total number of shares to be
included in the registration if that total number is less than the total number
of outstanding shares of Preferred;

                        (ii) second, among all Holders of Registrable Securities
of the class of Series A or Series B Preferred not requested by the Initiating
Holders, on a pro rata basis, as nearly as practicable up to the respective
amounts of Registrable Securities held by such Holders at the time of the filing
of the Registration Statement;

                        (iii) third, among all Holders of Registrable Securities
of the same class of Series A or Series B Preferred requested by the Initiating
Holders, on a pro rata basis, as nearly as practicable up to the respective
amounts of shares of Registrable Securities, held by such Holders and not
included in the allocation under section (i) above;

                        (iv) fourth, to the Company, as nearly as practicable up
to the amount of Registrable Securities held by the Company; and

                        (v) fifth, all Holders of Registrable Securities of the
Company who are either an officer or director of the Company, on a pro-rata
basis, as nearly as practicable up to the respective amounts of Registrable
Securities held by such Holders at the time of filing the Registration
Statement.

        No Registrable Securities excluded from the underwriting by reason of
the underwriter's marketing limitation shall be included in such registration.
To facilitate the allocation of shares in accordance with the above provisions,
the Company or the underwriters may round the number of shares allocated to any
Holder to the nearest one hundred (100) shares.

        If any Holder of Registrable Securities disapproves of the terms of the
underwriting, such person may elect to withdraw therefrom by written notice to
the Company, the managing underwriter and the Initiating Holders. The
Registrable Securities and/or other securities so withdrawn shall also be
withdrawn from registration.

        2.2 COMPANY REGISTRATION.

                (a) Notice of Registration. If at any time or from time to time
the Company shall determine to register any of its equity securities, either for
its own account or the account of a security holder or holders, other than (i) a
registration relating solely to employee benefit plans, or (ii) a registration
relating solely to a Rule 145 transaction, the Company will:

                        (i) promptly give to each Holder written notice thereof
and a reasonably detailed explanation of such Holder's rights and obligations
under this Section 2.2;


                                      -7-
<PAGE>   9

                        (ii) include in such registration (and any related
qualification under blue sky laws or other compliance), and in any underwriting
involved therein, all the Registrable Securities specified in a written request
or requests, made within thirty (30) days after mailing of such written notice
by the Company, by any Holder; and

                        (iii) use its best efforts to effect such registration
under the Securities Act of all Registrable Securities that the Holders have
requested that the Company register.

        Underwriting. If the registration of which the Company gives notice is
for a registered public offering involving an underwriting, the Company shall so
advise the Holders as a part of the written notice given pursuant to Section
2.2(a)(i). In such event the right of any Holder to registration pursuant to
Section 2.2 shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of Registrable Securities in the underwriting to
the extent provided herein. All Holders proposing to distribute their securities
through such underwriting shall (together with the Company and the other holders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the managing underwriter selected
for such underwriting by the Company. Notwithstanding any other provision of
this Section 2.2, if the managing underwriter determines that marketing factors
require a limitation of the number of shares to be underwritten, the managing
underwriter may limit the Registrable Securities to be included in such
registration. The Company shall so advise all Holders and other holders
distributing their securities through such underwriting and the number of shares
of Registrable Securities that may be included in the registration and
underwriting shall be allocated in the following manner: first, to the Company;
second, among all Holders of Series A and Series B Registrable Securities, on a
pro rata, as converted basis, as nearly as practicable to the respective amounts
of Registrable Securities held by such Holders at the time of filing the
Registration Statement; and third, among all Holders of Registrable Securities
who are either an officer or a director of the Company, in proportion, as nearly
as practicable to the respective amounts of Registrable Securities held by such
Holders at the time of filing the Registration Statement. No Registrable
Securities excluded from the underwriting by reason of the underwriter's
marketing limitation shall be included in such registration. To facilitate the
allocation of shares in accordance with the above provisions, the Company or the
underwriters may round the number of shares allocated to any Holder to the
nearest one hundred (100) shares.

                (b) To facilitate the allocation of shares in accordance with
the above provisions, the Company may round the number of shares allocated to
any Holder or holder to the nearest one hundred (100) shares. If any Holder
disapproves of the terms of any such underwriting, he may elect to withdraw
therefrom by written notice to the Company and the managing underwriter. Any
securities excluded or withdrawn from such underwriting shall be withdrawn from
such registration.

                (c) Right to Terminate Registration. The Company shall have the
right to terminate or withdraw any registration initiated by it under this
Section 2.2 prior to the effectiveness of such registration whether or not any
Holder has elected to include securities in such registration; provided, that
the Company shall have the obligation to pay all Registration Expenses in
connection with any such registration incurred pursuant to this Section 2.2.

        2.3 REGISTRATION ON FORM S-3.

                (a) If any Initiating Holder or Initiating Holders of the
then-outstanding Series A or Series B Registrable Securities request that the
Company file a registration statement on Form S-3 (or any successor form to Form
S-3) for a public offering of shares of the Registrable Securities the
reasonably anticipated aggregate offering price to the public of which, net of
underwriting discounts and commissions, would exceed $1,000,000, and the Company
is a registrant entitled to use Form S-3 to register the Series A or Series B
Registrable Securities for such an offering, the Company shall give prompt
notice of such proposed registration to all Holders and shall use its best
efforts to cause the Registrable Securities, and any other Registrable
Securities held by others who so notify the Company in writing within a
reasonable time that they wish to participate, to be registered for the offering
on such form and to cause the Registrable Securities to be qualified in such
jurisdictions as the Initiating Holder or Initiating Holders may reasonably
request; provided, however, that the Company shall not be required to effect
more than one registration requested by Initiating Holders of Series A
Preferred, and more than one registration requested by Initiating Holders of
Series B Preferred, pursuant to this Section 2.3 in any twelve (12) month
period. The substantive provisions of Section 2.1(b) shall be applicable to each
registration initiated under this Section 2.3.

                (b) Notwithstanding the foregoing, the Company shall not be
obligated to take any action pursuant to this Section 2.3: (i) in any particular
jurisdiction in which the Company would be required to execute a general consent
to service of process in effecting such registration, qualification or
compliance unless the Company is already subject to service in such jurisdiction
and except as may be required by the Securities Act; (ii) if the Company, within
ten (10) days of the receipt of the request of the Initiating Holders, gives
notice of its bona fide intention to effect the filing of a registration
statement with the Commission within sixty (60) days of receipt of such request
(other than with respect to a registration statement relating to a Rule 145
transaction, an offering solely to employees or any other registration which is
not appropriate for the registration of Registrable Securities); (iii) during
the period starting with the date sixty (60) days prior to the Company's
estimated date of filing of, and ending on the date three (3) months immediately
following, the effective date of any registration statement pertaining to
securities of the Company (other than a registration of securities in a Rule 145
transaction or with respect to an employee benefit plan), provided that the
Company is actively employing in good faith all reasonable efforts to cause such
registration statement to become effective; or (iv) if the Company shall furnish
to such Initiating Holder a certificate signed by the President of the Company
stating that in the good faith judgment of the Board of Directors it would be
seriously detrimental to the Company or its shareholders for registration
statements to be filed in the near future, then the Company's obligation to use
its best efforts to file a registration statement shall be deferred for a period
not to exceed one hundred twenty (120) days from the receipt of the request to
file such registration by such Initiating Holder, provided that such right to
delay a request may not be exercised by the Company more than once in any
twelve-month period.

        2.4 LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. From and after the
date of this Agreement, the Company shall not enter into any agreement granting
any Holder or prospective


                                      -9-
<PAGE>   11

holder of any securities of the Company registration rights with respect to such
securities unless (i) the rights of such holders to participate in Company
offerings are subordinate to the rights of the Holders under Sections 2.2 and
2.3 and such holder shall have no right to make a demand registration which
could result in such registration statement being declared effective prior to
October 1, 2002, or (ii) the Holders of fifty percent (50%) or more of the
Registrable Securities consent to the grant of such registration rights.

        2.5 EXPENSES OF REGISTRATION. All Registration Expenses incurred in
connection with registrations pursuant to Sections 2.1, 2.2 and 2.3, shall be
borne by the Company. Unless otherwise stated, all Selling Expenses relating to

such securities pro rata on the basis of the number of shares so registered.

        2.6 REGISTRATION PROCEDURES. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Section 2,
the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof. At its expense the Company will as expeditiously as possible:

                (a) prepare and file with the Commission a registration
statement with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for at least ninety (90)
days or until the distribution described in the registration statement has been
completed;

                (b) furnish to the Holders participating in such registration
and to the underwriters of the securities being registered such reasonable
number of copies of the registration statement and of each amendment and
supplement thereto, preliminary prospectus, final prospectus and such other
documents in conformity with the Securities Act as such Holders and underwriters
may reasonably request in order to facilitate the public offering of such
securities;

                (c) prepare and file with the Commission any amendments and
supplements to the registration statement and the prospectus included in the
registration statement as may be necessary to keep the registration statement
effective, in the case of a firm commitment underwritten public offering, until
each underwriter has completed the distribution of all securities purchased by
it and, in the case of any other offering, until the earlier of the sale of all
Registrable Securities covered thereby or 180 days after the effective date
thereof, provided that before filing a registration statement, or any amendments
or supplements thereto, the Company will furnish to the Holders and their
counsel, copies of all documents to be filed, which documents will be subject to
the review of such counsel;

                (d) use its best efforts to register or qualify the Registrable
Securities covered by the registration statement under the securities or Blue
Sky laws of such states as the selling Holders shall reasonably request, and do
any and all other acts and things that may be necessary or desirable to enable
the selling Holders to consummate the public sale or other disposition in such
states of the Registrable Securities owned by the selling Holder; provided,
however, that the Company shall not


                                      -10-
<PAGE>   12

be required in connection with this paragraph (d) to qualify as a foreign
corporation or execute a general consent to service of process in any
jurisdiction;

        (e) if the Company has delivered preliminary or final prospectuses to
the selling Holders and after having done so the prospectus is amended to comply
with the requirements of the Securities Act, the Company shall promptly notify
the selling Holders and, if requested, the selling Holders shall immediately
cease making offers of Registrable Securities and return all prospectuses to the
Company. The Company shall promptly provide the selling Holders with revised
prospectuses and, following receipt of the revised prospectuses, the selling
Holders shall be free to resume making offers of the Registrable Shares;

        (f) make available for inspection by Holders of the Registrable
Securities covered by the registration statement, by any underwriter
participating in any disposition to be effected pursuant to such registration
statement and by any attorney, accountant or other agent retained by such
Holders or any such underwriter, all pertinent financial and other records,
pertinent corporate documents and properties of the Company, officers, directors
and employees of the Company, and cause all of such officers, directors and
employees to supply all information reasonably requested by any such Holder,
underwriter, attorney, accountant or agent in connection with the registration
statement;

        (g) notify each Holder of any such Registrable Securities covered by
such registration statement, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act within the appropriate period
mentioned in Section 2.6(c), of the Company's becoming aware that 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, and at the request of any such Holder,
prepare and furnish to such Holder a reasonable number of copies of any
prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such Registrable Securities, such prospectus shall not include an
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 in
the light of the circumstances then existing;

        (h) use its best efforts to comply with all applicable rules and
regulations of the Securities and Exchange Commission, and make available to its
security holders, as soon as reasonably practicable (but not more than eighteen
(18) months) after the effective date of the registration statement, an earnings
statement which shall satisfy the provisions of Section 11(a) of the Securities
Act and the rules and regulations promulgated thereunder;

        (i) enter into such customary agreements (including an underwriting
agreement in customary form) and take such other actions as sellers of a
majority of shares of such Registrable Securities or the underwriters, if any,
reasonably request in order to expedite or facilitate the disposition of such
Registrable Securities; and


                                      -11-
<PAGE>   13

        (j) obtain a "cold comfort" letter or letters from the Company's
independent public accountants in customary form and covering matters of the
type customarily covered by "cold comfort" letters as the Holder or Holders of a
majority of the shares of such Registrable Securities shall reasonably request.

        2.7 INDEMNIFICATION.

                (a) The Company will indemnify and hold harmless each Holder and
each affiliate thereof, and their respective officers, directors, partners,
accountants, legal counsel and agents, and each person controlling such Holder
or affiliate thereof within the meaning of Section 15 of the Securities Act,
with respect to which registration, qualification or compliance has been
effected pursuant to this Section 2, and each person or entity that participates
as underwriter, if any, and each person who controls any underwriter within the
meaning of Section 15 of the Securities Act (each, a "Company Indemnified
Party"), against all expenses, claims, losses, damages or liabilities (joint or
several) (or actions in respect thereof), including any of the foregoing
incurred in settlement of any litigation, commenced or threatened, arising out
of or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any registration statement, prospectus, offering circular or
other document, or any amendment or supplement thereto, incident to any such
registration, qualification or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading, or any violation or alleged violation by the
Company of the Securities Act or any rule or regulation promulgated under the
Securities Act, the Exchange Act, state securities or Blue Sky Laws or otherwise
applicable to the Company in connection with any such registration,
qualification or compliance, and the Company will reimburse each such Company
Indemnified Party, for any legal and any other expenses reasonably incurred in
connection with investigating, preparing or defending any such claim, loss,
damage, liability, action or proceeding, provided that the Company will not be
liable in any such case to the extent that any such claim, loss, damage,
liability or expense arises out of or is based on any untrue statement or
omission or alleged untrue statement or omission, made in reliance upon and in
conformity with written information furnished to the Company by an instrument
duly executed by such Holder, controlling person or underwriter and stated to be
specifically for use therein.

                (b) Each Holder will, if Registrable Securities held by such
Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify the Company, each of
its directors and officers, each underwriter, if any, of the Company's
securities covered by such a registration statement, each person who controls
the Company or such underwriter within the meaning of Section 15 of the
Securities Act, and each other such Holder, each of its officers, directors and
partners, and each person controlling such Holder within the meaning of Section
15 of the Securities Act (collectively the "Holder Indemnified Parties"),
against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any such registration statement,
prospectus, offering circular or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein


                                      -12-
<PAGE>   14

not misleading, and will reimburse the Company, such Holders, such directors,
officers, persons, underwriters or control persons for any legal or any other
expenses reasonably incurred in connection with investigating or defending any
such claim, loss, damage, liability or action; provided that in each of the
foregoing pursuant to this Section 2.7(b) such Holder shall only indemnify the
Holder Indemnified Parties to the extent, but only to the extent, that such
untrue statement (or alleged untrue statement) or omission (or alleged omission)
is made in such registration statement, prospectus, offering circular or other
document in reliance upon and in conformity with written information furnished
to the Company by an instrument duly executed by such Holder and stated to be
specifically for use therein. Notwithstanding the foregoing, the liability of
each Holder under this subsection (b) shall be limited in an amount equal to the
initial public offering price of the shares sold by such Holder.

                (c) Each party entitled to indemnification under this Section
2.7 (the "Indemnified Party") shall give written notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has received written notice of the commencement of any action,
claim or proceeding as to which indemnity may be sought, and shall permit the
Indemnifying Party to assume the defense of any such claim or any litigation
resulting therefrom, provided that counsel for the Indemnifying Party, who shall
conduct the defense of such claim or litigation, shall be approved by the
Indemnified Party (whose approval shall not unreasonably be withheld), and the
Indemnified Party may participate in such defense at such party's expense (other
than the reasonable costs of investigation which shall be paid by the
Indemnifying Party), and provided further that the failure of any Indemnified
Party to give notice as provided herein shall not relieve the Indemnifying Party
of its obligations under this Section 2 unless but only to the extent that the
failure to give such notice is materially prejudicial to an Indemnifying Party's
ability to defend such action and provided further, that the Indemnifying Party
shall not assume the defense for matters as to which there is, in the reasonable
judgment of the Indemnified Party an actual or potential conflict of interest or
separate and different defenses. If there is such an actual or potential
conflict, then such Indemnified Party may employ separate counsel to represent
such Indemnified Party and the Indemnifying Party shall be liable for the
reasonable fees and expenses of separate counsel. No Indemnifying Party, in the
defense of any such claim or litigation, shall, except with the written consent
of each Indemnified Party, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect to such claim or litigation.

                (d) In order to provide for just and equitable contribution to
joint liability under the Securities Act in any case in which either (i) any
Holder exercising rights under this Agreement, or any controlling person of such
Holder, makes a claim for indemnification pursuant to this Section 2.7 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 2.7 provides for indemnification in
such case, or (ii) contribution under the Securities Act may be required on the
part of any such selling Holder or any such controlling person in


                                      -13-
<PAGE>   15

circumstances for which indemnification is provided under this Section 2.7;
then, and in each such case, the Company and such Holder will contribute to the
aggregate losses, claims, damages or liabilities to which they may be subject
(after contribution from others) in such proportion (i) so that such Holder
shall under no circumstances be responsible for more than the portion
represented by the percentage that the public offering price of its Registrable
Securities offered by and sold under the registration statement bears to the
public offering price of all securities offered by and sold under such
registration statement and (ii) so that the relative benefits received by each
party from the offering of the Registrable Securities (taking into account the
portion of the proceeds realized by each), the parties' relative knowledge and
access to information concerning the matter with respect to which the claim was
asserted, the opportunity to correct and prevent any misstatement or omission
and any other equitable considerations appropriate under the circumstances shall
be considered, and the Company and the other selling Holders are responsible for
the remaining portion; provided, however, that in any such case, (A) no such
Holder will be required to contribute any amount in excess of the public
offering price of all such Registrable Securities offered and sold by such
Holder pursuant to such registration statement; and (B) no person to the extent
that contribution is not permitted under Section 11(f) of the Securities Act
will be entitled to contribution.

                (e) The obligations of the Company and Holders under this
Section 2.7 shall survive the completion of any offering of Registrable
Securities in a registration statement, and otherwise.

                (f) The obligations of the parties under this Section 2 shall be
in addition to any liability which any party may otherwise have to any other
party.

        2.8 TERMINATION OF REGISTRATION RIGHTS. The rights granted pursuant to
this Agreement, to the extent not earlier terminated by the terms hereof, shall
terminate as to any Holder (i) five (5) years after the closing of an
underwritten public offering pursuant to an effective registration statement
under the Securities Act covering the offer and sale of common stock for the
account of the Company to the public, or (ii) at such time after the Company's
initial registered public offering as all Registrable Securities held by such
Holder can be sold without compliance with the registration requirements of the
Securities Act pursuant to Rule 144 (including without limitation Rule 144(k))
promulgated thereunder and such Holder owns less than 1% of the then outstanding
Registrable Securities.

        2.9 INFORMATION BY HOLDER. The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders, the Registrable Securities held by
them and the distribution proposed by such Holder or Holders as the Company may
reasonably request in writing, pertinent to such Holder and as shall be
reasonably required in connection with any registration, qualification or
compliance referred to in this Section 2.


                                      -14-

        2.10 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Securities to the public without registration, after such
time as a public market exists for the Common Stock of the Company, the Company
agrees to:

        (a) Make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, at all times after
the effective date that the Company becomes subject to the reporting
requirements of the Securities Act or the Securities Exchange Act of 1934, as
amended (the "EXCHANGE ACT").

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

        (c) So long as a Holder owns any Shares that are Restricted Securities
to furnish promptly to the Holder forthwith upon request a written statement by
the Company as to its compliance with the reporting requirements of said Rule
144 (at any time after ninety (90) days after the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents of the Company and other information in the possession of or
reasonably obtainable by the Company as a Holder may reasonably request in
availing itself of any rule or regulation of the Commission allowing a Holder to
sell any such securities without registration.

        2.11 TRANSFER OF REGISTRATION RIGHTS. The rights to cause the Company to
register securities granted Holders under Sections 2.1, 2.2 and 2.3 may be
assigned to a transferee or assignee in connection with any transfer or
assignment of Registrable Securities by a Holder provided that the Company is
given notice of the transfer or assignment and: (i) such transfer may otherwise
be effected in accordance with applicable securities laws, and (ii) either (A)
such assignee or transferee acquires at least 1,850,000 shares of Registrable
Securities or, if lesser, all of such shares held by the Holder or (B) such
transferee is an affiliate of the Holder (defined as a person that directly, or
indirectly through one or more intermediaries, controls or is controlled by, or
is under common control with the Holder). Notwithstanding the foregoing, the
rights to cause the Company to register securities may be assigned to any
constituent partner or retired partner of a Holder which is a partnership, or
any family member or trust for the benefit of any such individual holder,
without compliance with item (ii) above.

        2.12 STANDOFF AGREEMENT. Each Holder agrees in connection with the
public offering of the Company's securities, upon written request of the Company
or the managing underwriter, if any, any underwritten offering of the Company's
securities, not to sell, make any short sale of, loan, grant any option for the
purchase of, or otherwise dispose of any Registrable Securities (other than
those included in the registration) without the prior written consent of the
Company or such underwriter, as


                                      -15-
<PAGE>   17

the case may be, for such period of time (not to exceed one hundred eighty (180)
days)(the "Lockup Period") during the effectiveness of such registration
statement relating to such offering, provided that similar lockup agreements are
entered into by each of the Company's officers and directors and all Holders
holding not less than one percent (1%) of the outstanding capital stock of the
Company (including shares of Common Stock issuable upon the conversion of shares
of Preferred, or other convertible securities, or upon the exercise of options,
warrants or rights) and that such agreement shall not apply to Registrable
Securities included in the registration statement. In order to enforce the
provisions of this Section 2.1, the Company may impose stop-transfer
instructions with respect to the securities of the Company held by each Holder
not included in the registration statement until the end of the Lockup Period.

        2.13 MERGER ETC. The Company shall not, directly or indirectly, enter
into any merger, consolidation or reorganization in which the Company shall not
be the surviving corporation unless the proposed surviving corporation shall,
prior to such merger, consolidation or reorganization, agree in writing to
assume any and all of the obligations of the Company under this Agreement, and
for that purpose references hereunder to "Registrable Securities" shall be
deemed to be references to the securities which the Holders would be entitled to
receive in exchange for Registrable Securities under any such merger,
consolidation or reorganization; provided, however, that the provisions of this
Section 2.13 shall not apply in the event of any merger, consolidation or
reorganization in which the Company is not the surviving corporation if all
Holders are entitled to receive in exchange for their Registrable Securities
consideration consisting solely of (a) cash, (b) securities of the acquiring
corporation which may be immediately sold to the public without registration
under the Securities Act, or (c) securities of the acquiring corporation which
the acquiring corporation has agreed to register within 90 days of completion of
the transaction for resale to the public pursuant to the Securities Act.

                                    SECTION 3
                       PREEMPTIVE RIGHT ON COMPANY ISSUES

        3.1 COMPANY OFFER. The Company shall give the Holders forty (40) days'
prior written notice (the "Company Offer"), delivered or mailed as provided in
Section 5.4, of the Company's intention to sell or issue any equity securities
(the "Company Offered Securities"), other than an Exempt Issuance, stating the
material proposed terms of such sale or issuance and the identity of the Person,
if known, who has offered to purchase the Company Offered Securities. Such
notice shall include a representation to the Holders that, to the Company's
knowledge, a Person has made a bona fide offer to consummate such Company Offer,
and the Company has a good faith intention to sell such equity securities to
such Person on the terms specified. A Company Offer shall constitute an offer by
the Company, irrevocable for forty (40) days, to sell or issue to each Holders
such Holder's Pro Rata Portion of the Company Offered Securities on the same
terms as specified in the Company Offer or, if such terms provide for
consideration other than cash, for cash in an amount equal to the fair market
value of such noncash consideration (as determined by the Board) if the parties
cannot mutually agree upon such value.


                                      -16-
<PAGE>   18

        3.2 ACCEPTANCE OF COMPANY OFFER. Within forty (40) days after receipt of
a Company Offer, each Holder shall give an irrevocable written notice to the
Company (a "Section 3 Acceptance Notice") that (i) such Holder has elected to
purchase any of the Company Offered Securities. If such Holder fails to give a
Section 3 Acceptance Notice by the end of such forty (40) day period, such
Holder shall be deemed to have elected not to purchase any of the Company
Offered Securities.

        3.3 SALE TO THIRD PARTIES. If a Holder does not elect to purchase all of
its Pro Rata Portion of the Company Offered Securities, the Company shall have
the right, exercisable not later than ninety (90) days after the giving of the
Company Offer, to issue the Company Offered Securities not purchased by the
Holder on terms and conditions no more favorable than those set forth in the
Company Offer.

        3.4 CLOSING. The closing of any sale or issue of Company Offered
Securities to a Holder pursuant to this Section 3 shall take place on such date,
within thirty (30) days of the date of the Section 3 Acceptance Notice (subject
to extension to comply with any applicable law), as shall be agreed by the
Company and such Holder. At any such closing, the Company shall deliver to such
Holder certificate(s) representing the Company Offered Securities being issued,
registered in the name of such Holder or its nominee, against payment of the
applicable purchase price by check or wire transfer of same day funds.

        3.5 TERMINATION OF PREEMPTIVE RIGHTS. The rights of the Holders under
this Section 3 shall terminate upon such time as such Holder beneficially owns
less than 4,000,000 Shares.

                                    SECTION 4
                               INFORMATION RIGHTS

        4.1 FINANCIAL STATEMENTS AND OTHER INFORMATION.

        The Company hereby covenants and agrees that, so long as it is not
subject to the reporting requirements pursuant to Section 13 or 15(d) of the
Exchange Act, it will mail the following reports, provide access to the Company,
and provide prompt notification, as applicable, to each Holder for so long as
such Holder is a holder of at least 4,000,000 Shares (as adjusted for any stock
split, stock dividend, stock combination or other recapitalization, a
"RECAPITALIZATION"):

                (a) As soon as practicable after the end of each fiscal year,
and in any event within ninety (90) days thereafter, audited consolidated
balance sheets of the Company and its consolidated subsidiaries, if any, as of

generally accepted accounting principles and setting forth in each case in
comparative form the figures for the previous fiscal year, reported on without a
"going concern" or like qualification or exception, all in reasonable


                                      -17-
<PAGE>   19

detail and audited by nationally recognized independent public accountants

                (b) As soon as practicable after the end of each fiscal month of
the Company and in any event within thirty (30) business days thereafter, an
unaudited consolidated balance sheet of the Company and its subsidiaries, if
any, as of the end of each such monthly period, and unaudited consolidated
statements of income and retained earnings and unaudited consolidated statements
of changes in cash flows of the Company and its subsidiaries, if any, for such

                (d) The Company shall provide Holders and their representatives
with free and full access to the financial and other records, corporate
documents, business records and properties of the Company and reasonable access
to all officers, directors and employees of the Company, provided however, that
the Holders (and their representatives) agree to maintain the confidentiality of
such information.

                (e) The Company shall promptly notify the Holders of any (i)
material adverse change in the business, operations, prospects, assets or
condition, financial or otherwise, of the Company and (ii) litigation, claim or
proceeding or investigation brought or, to the best of the Company's knowledge,
threatened against the Company, or otherwise in respect of the Preferred or

condition, financial or otherwise or the validity of the Preferred.

        The information rights described in this Section 4.1 shall also apply
to: (i) any partner or retired partner of any such Holder which is a partnership
(subject to any limitations on the information rights of such a partnership's
limited partners which may be disclosed in writing to the Company by a general
partner of such partnership); (ii) any family member or trust for the benefits
of any such individual holder; or (iii) any transferee; provided, that the party
requesting information rights is a Holder of at least 4,000,000 Shares (as
adjusted for Recapitalizations) and the Company is given written notice thereof.

                                 XCARE.NET, INC.

                            INDEMNIFICATION AGREEMENT

        This Indemnification Agreement ("Agreement") is effective as of 19 by
and between XCare.net, Inc., a Delaware corporation (the "Company"), and
Indemnitee ("Indemnitee").

        WHEREAS, the Company desires to attract and retain the services of
highly qualified individuals, such as Indemnitee, to serve the Company and its
related entities;

        WHEREAS, in view of the considerations set forth above, the Company
desires that Indemnitee shall be indemnified by the Company as set forth herein;

        NOW, THEREFORE, the Company and Indemnitee hereby agree as set forth
below.

        1. Certain Definitions.

            (a) "Change in Control" shall mean, and shall be deemed to have
occurred if, on or after the date of this Agreement, (i) any "person" (as such
term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934,
as amended), other than a trustee or other fiduciary holding securities under an
employee benefit plan of the Company acting in such capacity or a corporation
owned directly or indirectly by the stockholders of the Company in substantially
the same proportions as their ownership of stock of the Company, becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing more than 50% of the total
voting power represented by the Company's then outstanding Voting Securities,
(ii) during any period of two consecutive years, individuals who at the
beginning of such period constitute the Board of Directors of the Company and
any new director whose election by the Board of Directors or nomination for
election by the Company's stockholders was approved by a vote of at least two
thirds (2/3) of the directors then still in office who either were directors at
the beginning of the period or whose election or nomination for election was
previously so approved, cease for any reason to constitute a majority thereof,
or (iii) the stockholders of the Company approve a merger or consolidation of
the Company with any other corporation other than a merger or consolidation
which would result in the Voting Securities of the Company outstanding
immediately prior thereto continuing to represent (either by remaining
outstanding or by being converted into Voting Securities of the surviving
entity) at least 80% of the total voting power represented by the Voting
Securities of the Company or such surviving entity outstanding immediately after
such merger or consolidation, or the stockholders of the Company approve a plan
of complete liquidation of the Company or an agreement for the sale or
disposition by the Company of (in one transaction or a series of related
transactions) all or substantially all of the Company's assets.

            (b) "Claim" shall mean any threatened, pending or completed action,
suit, proceeding or alternative dispute resolution mechanism, or any hearing,
inquiry or investigation that Indemnitee in good faith believes might lead to
the institution of any such action, suit, proceeding or alternative dispute
resolution mechanism, whether civil, criminal, administrative, investigative or
other.


<PAGE>   2


            (c) References to the "Company" shall include, in addition to
XCare.net, Inc., any constituent corporation (including any constituent of a
constituent) absorbed in a consolidation or merger to which XCare.net, Inc. (or
any of its wholly owned subsidiaries) is a party which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, employees, agents or fiduciaries, so that if Indemnitee is
or was a director, officer, employee, agent or fiduciary of such constituent
corporation, or is or was serving at the request of such constituent corporation
as a director, officer, employee, agent or fiduciary of another corporation,
partnership, joint venture, employee benefit plan, trust or other enterprise,
Indemnitee shall stand in the same position under the provisions of this
Agreement with respect to the resulting or surviving corporation as Indemnitee
would have with respect to such constituent corporation if its separate
existence had continued.

            (d) "Expenses" shall mean any and all expenses (including attorneys'
fees and all other costs, expenses and obligations incurred in connection with
investigating, defending, being a witness in or participating in (including on
appeal), or preparing to defend, to be a witness in or to participate in, any
action, suit, proceeding, alternative dispute resolution mechanism, hearing,
inquiry or investigation), judgments, fines, penalties and amounts paid in
settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) of any Claim regarding any
Indemnifiable Event and any federal, state, local or foreign taxes imposed on
the Indemnitee as a result of the actual or deemed receipt of any payments under
this Agreement.

            (e) "Expense Advance" shall mean an advance payment of Expenses to
Indemnitee pursuant to Section 3 (a).

            (f) "Indemnifiable Event" shall mean any event or occurrence related
to the fact that Indemnitee is or was a director, officer, employee, agent or
fiduciary of the Company, or any subsidiary of the Company, or is or was serving
at the request of the Company as a director, officer, employee, agent or
fiduciary of another corporation, partnership, joint venture, trust or other
enterprise, or by reason of any action or inaction on the part of Indemnitee
while serving in such capacity.

            (g) "Independent Legal Counsel" shall mean an attorney or firm of
attorneys, selected in accordance with the provisions of Section 2(c) hereof,
who shall not have otherwise performed services for the Company or Indemnitee
within the last three years (other than with respect to matters concerning the
rights of Indemnitee under this Agreement, or of other indemnitee under similar
indemnity agreements).

            (h) References to "other enterprises" shall include employee benefit
plans; references to "fines" shall include any excise taxes assessed on
Indemnitee with respect to an employee benefit plan; and references to "serving
at the request of the Company" shall include any service as a director, officer,
employee, agent or fiduciary of the Company which imposes duties on, or involves
services by, such director, officer, employee, agent or fiduciary with respect
to an employee benefit plan, its participants or its beneficiaries; and if
Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to
be in the interest of the participants and beneficiaries


                                      -2-
<PAGE>   3


of an employee benefit plan, Indemnitee shall be deemed to have acted in a
manner "not opposed to the best interests of the Company" as referred to in this
Agreement.

            (i) "Reviewing Party" shall mean any appropriate person or body
consisting of a member or members of the Company's Board of Directors or any
other person or body appointed by the Board of Directors who is not a party to
the particular Claim for which Indemnitee is seeking indemnification, or
Independent Legal Counsel.

            (j) "Voting Securities" shall mean any securities of the Company
that vote generally in the election of directors.

        2. Indemnification.

            (a) Indemnification of Expenses. The Company shall indemnify
Indemnitee to the fullest extent permitted by law if Indemnitee was or is or
becomes a party to or witness or other participant in, or is threatened to be
made a party to or witness or other participant in, any Claim by reason of (or
arising in part out of) any Indemnifiable Event against Expenses, including all
interest, assessments and other charges paid or payable in connection with or in
respect of such Expenses. Such payment of Expenses shall be made by the Company
as soon as practicable but in any event no later than five (5) business days
after written demand by Indemnitee therefor is presented to the Company.

            (b) Reviewing Party. Notwithstanding the foregoing, (i) the
obligations of the Company under Section 2(a) shall be subject to the condition
that the Reviewing Party shall not have determined (in a written opinion, in any
case in which the Independent Legal Counsel referred to in Section 2(c) hereof
is involved) that Indemnitee would not be permitted to be indemnified under
applicable law, and (ii) the obligation of the Company to make an Expense
Advance shall be subject to the condition that, if, when and to the extent that
the Reviewing Party determines that Indemnitee would not be permitted to be so
indemnified under applicable law, the Company shall be entitled to be reimbursed
by Indemnitee (who hereby agrees to reimburse the Company) for all such amounts
theretofore paid; provided, however, that if Indemnitee has commenced or
thereafter commences legal proceedings in a court of competent jurisdiction to
secure a determination that Indemnitee should be indemnified under applicable
law, any determination made by the Reviewing Party that Indemnitee would not be
permitted to be indemnified under applicable law shall not be binding and
Indemnitee shall not be required to reimburse the Company for any Expense
Advance until a final judicial determination is made with respect thereto (as to
which all rights of appeal therefrom have been exhausted or lapsed).
Indemnitee's obligation to reimburse the Company for any Expense Advance shall
be unsecured and no interest shall be charged thereon. If there has not been a
Change in Control, the Reviewing Party shall be selected by the Board of
Directors, and if there has been such a Change in Control (other than a Change
in Control which has been approved by a majority of the Company's Board of
Directors who were directors immediately prior to such Change in Control), the
Reviewing Party shall be the Independent Legal Counsel. If there has been no
determination by the Reviewing Party or if the Reviewing Party determines that
Indemnitee substantively would not be permitted to be indemnified in whole or in
part under applicable law, Indemnitee shall have the right to commence
litigation seeking an initial determination by the court or challenging any such
determination by the Reviewing Party or any aspect thereof, including the legal
or factual bases


                                      -3-
<PAGE>   4



therefor, and the Company hereby consents to service of process and to appear in
any such proceeding. Absent such litigation, any determination by the Reviewing
Party shall be conclusive and binding on the Company and Indemnitee.

            (c) Change in Control. The Company agrees that if there is a Change
in Control of the Company (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control), then with respect to all matters
thereafter arising concerning the rights of Indemnitee to payments of Expenses
and Expense Advances under this Agreement or any other agreement or under the
Company's Certificate of Incorporation or Bylaws as now or hereafter in effect,
Independent Legal Counsel, if desired by Indemnitee, shall be selected by
Indemnitee and approved by the Company (which approval shall not be unreasonably
withheld). Such counsel, among other things, shall render its written opinion to
the Company and Indemnitee as to whether and to what extent Indemnitee would be
permitted to be indemnified under applicable law and the Company agrees to abide
by such opinion. The Company agrees to pay the reasonable fees of the
Independent Legal Counsel referred to above and to indemnify fully such counsel
against any and all expenses (including attorneys' fees), claims, liabilities
and damages arising out of or relating to this Agreement or its engagement
pursuant hereto. Notwithstanding any other provision of this Agreement, the
Company shall not be required to pay Expenses of more than one Independent Legal
Counsel in connection with all matters concerning a single Indemnitee, and such
Independent Legal Counsel shall be the Independent Legal Counsel for any or all
other Indemnitees unless (i) the Company otherwise determines or (ii) any
Indemnitee shall provide a written statement setting forth in detail a
reasonable objection to such Independent Legal Counsel representing other
Indemnitees.

            (d) Mandatory Payment of Expenses. Notwithstanding any other
provision of this Agreement other than Section 10 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
Claim regarding any Indemnifiable Event, Indemnitee shall be indemnified against
all Expenses incurred by Indemnitee in connection therewith.

        3. Expenses; Indemnification Procedure.

            (a) Advancement of Expenses. The Company shall advance all Expenses
incurred by Indemnitee. The advances to be made hereunder shall be paid by the
Company to Indemnitee as soon as practicable but in any event no later than five
(5) business days after written demand by Indemnitee therefor to the Company.

            (b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a
condition precedent to Indemnitee's right to be indemnified under this
Agreement, give the Company notice in writing as soon as practicable of any
Claim made against Indemnitee for which indemnification will or could be sought
under this Agreement. Notice to the Company shall be directed to the Chief
Executive Officer of the Company at the address shown on the signature page of
this Agreement (or such other address as the Company shall designate in writing
to Indemnitee). In addition, Indemnitee shall give the Company such information
and cooperation as it may reasonably require and as shall be within Indemnitee's
power.


                                      -4-
<PAGE>   5


            (c) No Presumptions; Burden of Proof. For purposes of this
Agreement, the termination of any Claim by judgment, order, settlement (whether
with or without court approval) or conviction, or upon a plea of nolo
contendere, or its equivalent, shall not create a presumption that Indemnitee
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law. In addition, neither the failure of the Reviewing Party to have made a
determination as to whether Indemnitee has met any particular standard of
conduct or had any particular belief, nor an actual determination by the
Reviewing Party that Indemnitee has not met such standard of conduct or did not
have such belief, prior to the commencement of legal proceedings by Indemnitee
to secure a judicial determination that Indemnitee should be indemnified under
applicable law, shall be a defense to Indemnitee's claim or create a presumption
that Indemnitee has not met any particular standard of conduct or did not have
any particular belief. In connection with any determination by the Reviewing
Party or otherwise as to whether the Indemnitee is entitled to be indemnified
hereunder, the burden of proof shall be on the Company to establish that
Indemnitee is not so entitled.

            (d) Notice to Insurers. If, at the time of the receipt by the
Company of a notice of a Claim pursuant to Section 3(b) hereof, the Company has
liability insurance in effect which may cover such Claim, the Company shall give
prompt notice of the commencement of such Claim to the insurers in accordance
with the procedures set forth in the respective policies. The Company shall
thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of the Indemnitee, all amounts payable as a result of such Claim in
accordance with the terms of such policies.

            (e) Selection of Counsel. In the event the Company shall be
obligated hereunder to pay the Expenses of any Claim, the Company, if
appropriate, shall be entitled to assume the defense of such Claim with counsel
approved by Indemnitee (not to be unreasonably withheld) upon the delivery to
Indemnitee of written notice of the Company's election so to do. After delivery
of such notice, approval of such counsel by Indemnitee and the retention of such
counsel by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees of counsel subsequently incurred by Indemnitee with
respect to the same Claim; provided that, (i) Indemnitee shall have the right to
employ Indemnitee's separate counsel in any such Claim at Indemnitee's expense
and (ii) if (A) the employment of separate counsel by Indemnitee has been
previously authorized by the Company, (B) Indemnitee shall have reasonably
concluded that there may be a conflict of interest between the Company and
Indemnitee in the conduct of any such defense, or (C) the Company shall not
continue to retain such counsel to defend such Claim, then the fees and expenses
of Indemnitee's separate counsel shall be at the expense of the Company.

        4. Additional Indemnification Rights, Nonexclusivity.

            (a) Scope. The Company hereby agrees to indemnify the Indemnitee to
the fullest extent permitted by law, notwithstanding that such indemnification
is not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the Company's Bylaws or by statute. In
the event of any change after the date of this Agreement in any applicable law,
statute or rule which expands the right of a Delaware corporation to indemnify a
member of its board of directors or an officer, employee, agent or fiduciary, it
is the intent of the parties hereto that Indemnitee shall enjoy by this
Agreement the greater benefits afforded by such



                                      -5-
<PAGE>   6



change. In the event of any change in any applicable law, statute or rule which
narrows the right of a Delaware corporation to indemnify a member of its board
of directors or an officer, employee, agent or fiduciary, such change, to the
extent not otherwise required by such law, statute or rule to be applied to this
Agreement, shall have no effect on this Agreement or the parties' rights and
obligations hereunder except as set forth in Section 9(a) hereof.

            (b) Nonexclusivity. The indemnification provided by this Agreement
shall be in addition to any rights to which Indemnitee may be entitled under the
Company's Certificate of Incorporation, its Bylaws, any other agreement, any
vote of stockholders or disinterested directors, the General Corporation Law of
the State of Delaware, or otherwise. The indemnification provided under this
Agreement shall continue as to Indemnitee for any action taken or not taken
while serving in an indemnified capacity even though Indemnitee may have ceased
to serve in such capacity.

        5. No Duplication of Payments. The Company shall not be liable under
this Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, provision of the Company's Certificate of
Incorporation, bylaw or otherwise) of the amounts otherwise indemnifiable
hereunder.

        6. Partial Indemnification. If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however, for
all of the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

        7. Mutual Acknowledgment. Both the Company and Indemnitee acknowledge
that in certain instances, federal law or applicable public policy may prohibit
the Company from indemnifying its directors, officers, employees, agents or
fiduciaries under this Agreement or otherwise. Indemnitee understands and
acknowledges that the Company has undertaken or may be required in the future to
undertake with the Securities and Exchange Commission to submit the question of
indemnification to a court in certain circumstances for a determination of the
Company's right under public policy to indemnify Indemnitee.

        8. Liability Insurance. To the extent the Company maintains liability
insurance applicable to directors, officers, employees, agents or fiduciaries,
Indemnitee shall be covered by such policies in such a manner as to provide
Indemnitee the same rights and benefits as are provided to the most favorably
insured of the Company's directors, if Indemnitee is a director; or of the
Company's officers, if Indemnitee is not a director of the Company but is an
officer; or of the Company's key employees, agents or fiduciaries, if Indemnitee
is not an officer or director but is a key employee, agent or fiduciary.

        9. Exceptions. Notwithstanding any other provision of this Agreement,
the Company shall not be obligated pursuant to the terms of this Agreement:

            (a) Excluded Action or Omissions. To indemnify Indemnitee for acts,
omissions or transactions from which Indemnitee may not be relieved of liability
under applicable law.



                                      -6-
<PAGE>   7



            (b) Claims Initiated by Indemnitee. To indemnify or advance expenses
to Indemnitee with respect to Claims initiated or brought voluntarily by
Indemnitee and not by way of defense, except (i) with respect to actions or
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other agreement or insurance policy or under the Company's
Certificate of Incorporation or Bylaws now or hereafter in effect relating to
Claims for Indemnifiable Events, (ii) in specific cases if the Board of
Directors has approved the initiation or bringing of such Claim, or (iii) as
otherwise required under Section 145 of the Delaware General Corporation Law,
regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification, advance expense payment or insurance recovery, as the case may
be.

            (c) Lack of Good Faith, To indemnify Indemnitee for any expenses
incurred by the Indemnitee with respect to any proceeding instituted by
Indemnitee to enforce or interpret this Agreement, if a court of competent
jurisdiction determines that each of the material assertions made by the
Indemnitee in such proceeding was not made in good faith or was frivolous.

            (d) Claims Under Section 16(b). To indemnify Indemnitee for expenses
and the payment of profits arising from the purchase and sale by Indemnitee of

        10. Period of Limitations. No legal action shall be brought and no cause
of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal
action within such two-year period; provided, however that if any shorter period
of limitations is otherwise applicable to any such cause of action, such shorter
period shall govern.

        11. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall constitute an original.

        12. Binding Effect, Successors and Assigns. This Agreement shall be
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors, assigns (including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business or assets of the Company), spouses, heirs and
personal and legal representatives. The Company shall require and cause any
successor (whether direct or indirect, and whether by purchase, merger,
consolidation or otherwise) to all, substantially all, or a substantial part, of
the business or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and 'agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform if no such succession had taken place. This Agreement
shall continue in effect regardless of whether Indemnitee continues to serve as
a director, officer, employee, agent or fiduciary (as applicable) of the Company
or of any other enterprise at the Company's request.

        13. Attorneys' Fees. In the event that any action is instituted by
Indemnitee under this Agreement or under any liability insurance policies
maintained by the Company to enforce or interpret any of the terms hereof or
thereof, Indemnitee shall be entitled to be paid all Expenses



                                      -7-
<PAGE>   8

incurred by Indemnitee with respect to such action, regardless of whether
Indemnitee is ultimately successful in such action, and shall be entitled to the
advancement of Expenses with respect to such action, unless as a part of such
action a court of competent jurisdiction over such action determines that each
of the material assertions made by Indemnitee as a basis for such action were
not made in good faith or were frivolous. In the event of an action instituted
by or in the name of the Company under this Agreement to enforce or interpret
any of the terms of this Agreement, Indemnitee shall be entitled to be paid all
Expenses incurred by Indemnitee in defense of such action (including costs and
expenses incurred with respect to Indemnitee's counterclaims and cross-claims
made in such action), and shall be entitled to the advancement of Expenses with
respect to such action, unless as a part of such action a court having
jurisdiction over such action determines that each of Indemnitee's material
defenses to such action were made in bad faith or were frivolous.

        14. Notice. All notices, requests, demands and other communications
under this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and signed for by the party addressed, on the date of such

        15. Consent to Jurisdiction. The Company and Indemnitee each hereby
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be commenced, prosecuted and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be
the exclusive and only proper forum for adjudicating such a claim.

        16. Severability. The provisions of this Agreement shall be severable in
the event that any of the provisions hereof (including any provision within a
single section, paragraph or sentence) are held by a court of competent
jurisdiction to be invalid, void or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including, without limitations, each portion of this Agreement containing any
provision held to be invalid, void or otherwise unenforceable, that is not
itself invalid, void or unenforceable) shall be construed so as to give effect
to the intent manifested by the provision held invalid, illegal or
unenforceable.

        17. Choice of Law. This Agreement shall be governed by and its
provisions construed and enforced in accordance with the laws of the State of
Delaware as applied to contracts between Delaware residents entered into and to
be performed entirely within the State of Delaware.

        18. Subrogation. In the event of payment under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
effectively to bring suit to enforce such rights.

        19. Amendment and Termination. No amendment, modification, termination
or cancellation of this Agreement shall be effective unless it is in writing
signed by both the parties


                                      -8-
<PAGE>   9

hereto. No waiver of any of the provisions of this Agreement shall be deemed to
be or shall constitute a waiver of any other provisions hereof (whether or not
similar), nor shall such waiver constitute a continuing waiver.

        20. Integration and Entire Agreement. This Agreement sets forth the
entire understanding between the parties hereto and supersedes and merges all
previous written and oral negotiations, commitments, understandings and
agreements relating to the subject matter hereof between the parties hereto.

        21. No Construction as Employment Agreement. Nothing contained in this
Agreement shall be construed as giving Indemnitee any right to be retained in
the employ of the Company or any of its subsidiaries or affiliated entities.

Options, as determined by the Administrator at the time of grant. Stock Purchase

                If an Option or Stock Purchase Right expires or becomes
unexercisable without having been exercised in full, or is surrendered pursuant
to an Option Exchange Program, the unpurchased Shares which were subject thereto
shall become available for future grant or sale under the Plan (unless the Plan
has terminated). However, Shares that have actually been issued under the Plan,
upon exercise of either an Option or Stock Purchase Right, shall not be returned
to the Plan and shall not become available for future distribution under the
Plan, except that if Shares of Restricted Stock are repurchased by the Company
at their original purchase price, such Shares shall become available for future
grant under the Plan.

        4. Administration of the Plan.

                (a) The Plan shall be administered by the Board or a Committee

                                      -3-
<PAGE>   4

                        (ii) to select the Service Providers to whom Options and
Stock Purchase Rights may from time to time be granted hereunder;

                        (iii) to determine the number of Shares to be covered by
each such award granted hereunder;

                        (iv) to approve forms of agreement for use under the
Plan;

                        (v) to determine the terms and conditions, of any Option
or Stock Purchase Right granted hereunder. Such terms and conditions include,
but are not limited to, the exercise price, the time or times when Options or
Stock Purchase Rights may be exercised (which may be based on performance
criteria), any vesting acceleration or waiver of forfeiture restrictions, and
any restriction or limitation regarding any Option or Stock Purchase Right of
the Common Stock relating thereto, based in each case on such factors as the
Administrator, in its sole discretion, shall determine;

                        (vi) to determine whether and under what circumstances
an Option may be settled in cash under subsection 9(e) instead of Common Stock;

                        (vii) to reduce the exercise price of any Option to the
then current Fair Market Value if the Fair Market Value of the Common Stock
covered by such Option has declined since the date the Option was granted;

                        (viii) to initiate an Option Exchange Program;

                        (ix) to prescribe, amend and rescind rules and
regulations relating to the Plan, including rules and regulations relating to
sub-plans established for the purpose of qualifying for preferred tax treatment
under foreign tax laws;

                        (x) to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option or Stock Purchase Right that number of Shares
having a Fair Market Value equal to the amount required to be withheld. The Fair
Market Value of the Shares to be withheld shall be determined on the date that
the amount of tax to be withheld is to be determined. All elections by Optionees
to have Shares withheld for this purpose shall be made in such form and under
such conditions as the Administrator may deem necessary or advisable; and

                        (xi) to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan.

                (c) Effect of Administrator's Decision. All decisions,

Employees.


                                      -4-
<PAGE>   5

        6. Limitations.

                (a) Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

                (b) Neither the Plan nor any Option or Stock Purchase Right
shall confer upon any Optionee any right with respect to continuing the
Optionee's relationship as a Service Provider with the Company, nor shall it
interfere in any way with his or her right or the Company's right to terminate
such relationship at any time, with or without cause.

                (c) The following limitations shall apply to grants of Options:

                        (i)No Service Provider shall be granted, in any fiscal
year of the Company, Options to purchase more than 10,500,000 Shares.

                        (ii) In connection with his or her initial service, a
Service Provider may be granted Options to purchase up to an additional
10,500,000 Shares which shall not count against the limit set forth in
subsection (i) above.

                        (iii) The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 13.

                        (iv) If an Option is cancelled in the same fiscal year
of the Company in which it was granted (other than in connection with a
transaction described in Section 13), the cancelled Option will be counted
against the limits set forth in subsections (i) and (ii) above. For this
purpose, if the exercise price of an Option is reduced, the transaction will be
treated as a cancellation of the Option and the grant of a new Option.

        7. Term of Plan. Subject to Section 19 of the Plan, the amendment and
restatement of the Plan shall become effective upon the date of stockholder
approval of the Plan in October, 1999; provided, however, that amendments that
would cause the Plan or Options granted hereunder to fail to comply with
applicable Delaware "blue sky" securities law shall not become effective until
the IPO Effective Date. It shall continue in effect for a term of ten (10) years
unless sooner terminated under Section 15 of the Plan.

        8. Term of Option. The term of each Option shall be stated in the Option
Agreement; provided, however, that the term shall be no more than ten (10) years
from the date of grant thereof. In the case of an Incentive Stock Option granted
to an Optionee who, at the time the Option is granted, owns stock representing
more than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the term of the Option shall be five (5)
years from the date of grant or such shorter term as may be provided in the
Option Agreement.

        9. Option Exercise Price and Consideration.

                (a) The per share exercise price for the Shares to be issued
upon exercise of an Option shall be such price as is determined by the
Administrator, but shall be subject to the following:

                        (i)In the case of an Incentive Stock Option

                                (A) granted to an Employee who, at the time of
grant of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary,
the exercise price shall be no less than 110% of the Fair Market Value per Share
on the date of grant.

                                (B) granted to any other Employee, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                        (ii) In the case of a Nonstatutory Stock Option, the per
Share exercise price shall be determined by the Administrator.

                        (iii) Notwithstanding the foregoing, Options may be
granted with a per Share exercise price other than as required above pursuant to
a merger or other corporate transaction.

                (b) The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined
by the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant). Such consideration may consist of (1) cash,
(2) check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six months on the date of surrender, and (y) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which such Option shall be exercised, (5) consideration received by the Company
under a cashless exercise program implemented by the Company in connection with
the Plan, or (6) any combination of the foregoing methods of payment. In making
its determination as to the type of consideration to accept, the Administrator
shall consider if acceptance of such consideration may be reasonably expected to
benefit the Company.

        10. Exercise of Option.

                (a) Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable according to the terms hereof at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement. Unless the Administrator provides otherwise, vesting of
Options granted hereunder shall be tolled during any unpaid leave of absence. An
Option may not be exercised for a fraction of a Share.

                        An Option shall be deemed exercised when the Company
receives: (i) written or electronic notice of exercise (in accordance with the
Option Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of


                                      -6-
<PAGE>   7

an Option shall be issued in the name of the Optionee or, if requested by the
Optionee, in the name of the Optionee and his or her spouse. Until the Shares
are issued (as evidenced by the appropriate entry on the books of the Company or
of a duly authorized transfer agent of the Company), no right to vote or receive
dividends or any other rights as a shareholder shall exist with respect to the
Shares, notwithstanding the exercise of the Option. The Company shall issue (or
cause to be issued) such Shares promptly after the Option is exercised. No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the Shares are issued, except as provided in Section 12 of
the Plan.

                        Exercise of an Option in any manner shall result in a
decrease in the number of Shares thereafter available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

                (b) Termination of Relationship as a Service Provider. If an
Optionee ceases to be a Service Provider, such Optionee may exercise his or her
Option within such period of time as is specified in the Option Agreement (of at
least thirty (30) days) to the extent that the Option is vested on the date of
termination (but in no event later than the expiration of the term of the Option
as set forth in the Option Agreement). In the absence of a specified time in the
Option Agreement, the Option shall remain exercisable for three (3) months
following the Optionee's termination. If, on the date of termination, the
Optionee is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option shall revert to the Plan. If, after termination,
the Optionee does not exercise his or her Option within the time specified by
the Administrator, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

                (c) Disability of Optionee. If an Optionee ceases to be a
Service Provider as a result of the Optionee's total and permanent disability,
as defined in Section 22(e)(3) of the Code, the Optionee may exercise his or her
Option within such period of time as is specified in the Option Agreement to the
extent the Option is vested on the date of termination (but in no event later
than the expiration of the term of such Option as set forth in the Option
Agreement). In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination. If, on the date of termination, the Optionee is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the
Option shall revert to the Plan. If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

                (d) Death of Optionee. If an Optionee dies while a Service
Provider, the Option may be exercised within such period of time as is specified
in the Option Agreement (but in no event later than the expiration of the term
of such Option as set forth in the Notice of Grant), by the Optionee's estate or
by a person who acquires the right to exercise the Option by bequest or
inheritance, but only to the extent that the Option is vested on the date of
death. In the absence of a specified time in the Option Agreement, the Option
shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to his or
her entire Option, the Shares covered by the unvested portion of the Option
shall immediately revert to the Plan. The Option may be exercised by the
executor or administrator of the Optionee's estate or, if none, by the person(s)
entitled to exercise the Option under the Optionee's will or the laws of


                                      -7-
<PAGE>   8

descent or distribution. If the Option is not so exercised within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

                (e) Buyout Provisions. The Administrator may at any time offer
to buy out for a payment in cash or Shares, an Option previously granted, based
on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

        11. Stock Purchase Rights.

                (a) Rights to Purchase. Stock Purchase Rights may be issued
either alone, in addition to, or in tandem with other awards granted under the
Plan and/or cash awards made outside of the Plan. After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing or electronically of the terms, conditions and
restrictions related to the offer, including the number of Shares that such
person shall be entitled to purchase, the price to be paid, and the time within
which such person must accept such offer. The offer shall be accepted by
execution of a Restricted Stock purchase agreement in the form determined by the
Administrator.

                (b) Repurchase Option. Unless the Administrator determines
otherwise, the Restricted Stock purchase agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's service with the Company for any reason (including death or
disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock purchase agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at such rate as the
Administrator may determine.

                (c) Other Provisions. The Restricted Stock purchase agreement
shall contain such other terms, provisions and conditions not inconsistent with
the Plan as may be determined by the Administrator in its sole discretion.

                (d) Rights as a Shareholder. Once the Stock Purchase Right is
exercised, the purchaser shall have rights equivalent to those of a shareholder
and shall be a shareholder when his or her purchase is entered upon the records
of the duly authorized transfer agent of the Company. No adjustment shall be
made for a dividend or other right for which the record date is prior to the
date the Stock Purchase Right is exercised, except as provided in Section 13 of
the Plan.

        12. Non-Transferability of Options and Stock Purchase Rights. Unless
determined otherwise by the Administrator, Options and Stock Purchase Rights may
not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any
manner other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee. If the
Administrator makes an Option or Stock Purchase Right transferable, such Option
or Stock Purchase Right shall contain such additional terms and conditions as
the Administrator deems appropriate.


                                      -8-
<PAGE>   9

        13. Adjustments Upon Changes in Capitalization, Merger or Asset Sale.

                (a) Changes in Capitalization. Subject to any required action by
the shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company. The conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Option or Stock Purchase Right.

                (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until fifteen (15) days prior to
such transaction as to all of the Optioned Stock covered thereby, including
Shares as to which the Option would not otherwise be exercisable. In addition,
the Administrator may provide that any Company repurchase option applicable to
any Shares purchased upon exercise of an Option or Stock Purchase Right shall
lapse as to all such Shares, provided the proposed dissolution or liquidation
takes place at the time and in the manner contemplated. To the extent it has not
been previously exercised, an Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

                (c) Merger or Asset Sale. In the event of a merger of the
Company with or into another corporation, or the sale of substantially all of
the assets of the Company, each outstanding Option and Stock Purchase Right
shall be assumed or an equivalent option or right substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation. In the event
that the successor corporation refuses to assume or substitute for the Option or
Stock Purchase Right, the Optionee shall fully vest in and have the right to
exercise the Option or Stock Purchase Right as to all of the Optioned Stock,
including Shares as to which it would not otherwise be vested or exercisable. If
an Option or Stock Purchase Right becomes fully vested and exercisable in lieu
of assumption or substitution in the event of a merger or sale of assets, the
Administrator shall notify the Optionee in writing or electronically that the
Option or Stock Purchase Right shall be fully exercisable for a period of
fifteen (15) days from the date of such notice, and the Option or Stock Purchase
Right shall terminate upon the expiration of such period. For the purposes of
this paragraph, the Option or Stock Purchase Right shall be considered assumed
if, following the merger or sale of assets, the option or right confers the
right to purchase or receive, for each Share of


                                      -9-
<PAGE>   10

Optioned Stock subject to the Option or Stock Purchase Right immediately prior
to the merger or sale of assets, the consideration (whether stock, cash, or
other securities or property) received in the merger or sale of assets by
holders of Common Stock for each Share held on the effective date of the
transaction (and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the merger or sale of
assets is not solely common stock of the successor corporation or its Parent,
the Administrator may, with the consent of the successor corporation, provide
for the consideration to be received upon the exercise of the Option or Stock
Purchase Right, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right, to be solely common stock of the successor corporation or its
Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.

        14. Time of Granting Options and Stock Purchase Rights. The date of
grant of an Option or Stock Purchase Right shall, for all purposes, be the date
on which the Administrator makes the determination granting such Option or Stock
Purchase Right, or such other date as is determined by the Administrator. Notice
of the determination shall be given to each Service Provider to whom an Option
or Stock Purchase Right is so granted within a reasonable time after the date of
such grant.

        15. Amendment and Termination of the Plan.

                (a) Amendment and Termination. The Board may at any time amend,
alter, suspend or terminate the Plan.

                (b) Shareholder Approval. The Board shall obtain shareholder
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

                (c) Effect of Amendment or Termination. No amendment,
alteration, suspension or termination of the Plan shall impair the rights of any
Optionee, unless mutually agreed otherwise between the Optionee and the
Administrator, which agreement must be in writing and signed by the Optionee and
the Company. Termination of the Plan shall not affect the Administrator's
ability to exercise the powers granted to it hereunder with respect to Options
granted under the Plan prior to the date of such termination.

        16. Conditions Upon Issuance of Shares.

                (a) Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

                (b) Investment Representations. As a condition to the exercise
of an Option, the Administrator may require the person exercising such Option to
represent and warrant at the time of any such exercise that the Shares are being
purchased only for investment and without any present intention to sell or
distribute such Shares if, in the opinion of counsel for the Company, such a
representation is required.


                                      -10-
<PAGE>   11

        17. Inability to Obtain Authority. The inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

        18. Reservation of Shares. The Company, during the term of this Plan,
shall at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

        19. Shareholder Approval. The Plan shall be subject to approval by the
shareholders of the Company within twelve (12) months after the date the Plan is
adopted. Such shareholder approval shall be obtained in the degree and manner
required under Applicable Laws.

<PAGE>   13

        Termination Period:

        This Option shall be exercisable for three months after Optionee ceases
to be a Service Provider. Upon Optionee's death or disability, this Option may
be exercised for one year after Optionee ceases to be a Service Provider. In no

II. AGREEMENT

        1. Grant of Option. The Plan Administrator of the Company hereby grants
to the Optionee named in the Notice of Grant (the "Optionee"), an option (the
"Option") to purchase the number of Shares set forth in the Notice of Grant, at
the exercise price per Share set forth in the Notice of Grant (the "Exercise
Price"), and subject to the terms and conditions of the Plan, which is
incorporated herein by reference. Subject to Section 14(c) of the Plan, in the
event of a conflict between the terms and conditions of the Plan and this Option
Agreement, the terms and conditions of the Plan shall prevail.

        If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option as
defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds
the $100,000 rule of Code Section 422(d), this Option shall be treated as a
Nonstatutory Stock Option ("NSO").

        2. Exercise of Option.

                (a) Right to Exercise.

                        i) Subject to subsections 2(a)(ii) and 2(a) iii below,
this Option shall be exercisable cumulatively according to the vesting schedule
set forth in the Notice of Grant.

                        ii) This Option may not be exercised for a fraction of a
Share.

                (b) Method of Exercise. This Option shall be exercisable by
delivery of an exercise notice in the form attached as Exhibit A (the "Exercise
Notice") which shall state the election to exercise the Option, the number of
Shares with respect to which the Option is being exercised, and such other
representations and agreements as may be required by the Company. The Exercise
Notice shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares. This Option shall be deemed to be exercised upon receipt by
the Company of such fully executed Exercise Notice accompanied by the aggregate
Exercise Price.

                No Shares shall be issued pursuant to the exercise of an Option
unless such issuance and such exercise complies with Applicable laws. Assuming
such compliance, for income tax purposes the Shares shall be considered
transferred to the Optionee on the date on which the Option is exercised with
respect to such Shares.

        3. Optionee's Representations. In the event the Shares have not been
registered under the Securities Act of 1933, as amended, at the time this Option
is exercised, the Optionee shall, if


                                      -2-
<PAGE>   14

required by the Company, concurrently with the exercise of all or any portion of
this Option, deliver to the Company his or her Investment Representation
Statement in the form attached hereto as Exhibit B.

        4. Lock-Up Period. Optionee hereby agrees that, if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
other period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act. Such restriction shall apply only to the first registration
statement of the Company to become effective under the Securities Act that
includes securities to be sold on behalf of the Company to the public in an
underwritten public offering under the Securities Act. The Company may impose
stop-transfer instructions with respect to securities subject to the foregoing
restrictions until the end of such Market Standoff Period.

        5. Method of Payment. Payment of the aggregate Exercise Price shall be
by any of the following, or a combination thereof, at the election of the
Optionee:

                (a) cash or check;

                (b) consideration received by the Company under a formal
cashless exercise program adopted by the Company in connection with the Plan; or

                (c) surrender of other Shares which, (i) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, and (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares.

        6. Restrictions on Exercise. This Option may not be exercised until such
time as the Plan has been approved by the shareholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any Applicable
Law.

        7. Non-Transferability of Option. This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by Optionee. The terms of
the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

        8. Term of Option. This Option may be exercised only within the term set
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.

        9. Tax Consequences. Set forth below is a brief summary as of the date
of this Option of some of the federal tax consequences of exercise of this
Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE,
AND THE TAX LAWS AND


                                      -3-
<PAGE>   15

REGULATIONS ARE SUBJECT TO CHANGE. THE OPTIONEE SHOULD CONSULT A TAX ADVISER
BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

                (a) Exercise of ISO. If this Option qualifies as an ISO, there
will be no regular federal income tax liability upon the exercise of the Option,
although the excess, if any, of the Fair Market Value of the Shares on the date
of exercise over the Exercise Price will be treated as an adjustment to the
alternative minimum tax for federal tax purposes and may subject the Optionee to
the alternative minimum tax in the year of exercise.

                (b) Exercise of Nonstatutory Stock Option. There may be a
regular federal income tax liability upon the exercise of a Nonstatutory Stock
Option. The Optionee will be treated as having received compensation income
(taxable at ordinary income tax rates) equal to the excess, if any, of the Fair
Market Value of the Shares on the date of exercise over the Exercise Price. If
Optionee is an Employee or a former Employee, the Company will be required to
withhold from Optionee's compensation or collect from Optionee and pay to the
applicable taxing authorities an amount in cash equal to a percentage of this
compensation income at the time of exercise, and may refuse to honor the
exercise and refuse to deliver Shares if such withholding amounts are not
delivered at the time of exercise.

                (c) Disposition of Shares. In the case of an NSO, if Shares are
held for at least one year, any gain realized on disposition of the Shares will
be treated as long-term capital gain for federal income tax purposes. In the
case of an ISO, if Shares transferred pursuant to the Option are held for at
least one year after exercise and of at least two years after the Date of Grant,
any gain realized on disposition of the Shares will also be treated as long-term
capital gain for federal income tax purposes. If Shares purchased under an ISO
are disposed of within one year after exercise or two years after the Date of
Grant, any gain realized on such disposition will be treated as compensation
income (taxable at ordinary income rates) to the extent of the difference
between the Exercise Price and the lesser of (1) the Fair Market Value of the
Shares on the date of exercise, or (2) the sale price of the Shares. Any
additional gain will be taxed as capital gain, short-term or long-term depending
on the period that the ISO Shares were held.

                (d) Notice of Disqualifying Disposition of ISO Shares. If the
Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant, or (2) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition. Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

        10. Entire Agreement; Governing Law. The Plan is incorporated herein by
reference. The Plan and this Option Agreement constitute the entire agreement of
the parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a writing signed by the Company and
Optionee. This agreement is governed by the internal substantive laws but not
the choice of law rules of Colorado.


                                      -4-
<PAGE>   16

        11. No Guarantee of Continued Service. OPTIONEE ACKNOWLEDGES AND AGREES
THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED
ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (NOT THROUGH
THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES
HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE
TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
NOT INTERFERE IN ANY WAY WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR
WITHOUT CAUSE.

        Optionee acknowledges receipt of a copy of the Plan and represents that
he or she is familiar with the terms and provisions thereof, and hereby accepts
this Option subject to all of the terms and provisions thereof. Optionee has
reviewed the Plan and this Option in their entirety, has had an opportunity to
obtain the advice of counsel prior to executing this Option and fully
understands all provisions of the Option. Optionee hereby agrees to accept as
binding, conclusive and final all decisions or interpretations of the
Administrator upon any questions arising under the Plan or this Option. Optionee
further agrees to notify the Company upon any change in the residence address
indicated below.

                                 EXERCISE NOTICE

XCARE.NET, INC.
6400 S. Fiddler's Green Circle
Suite 540
Englewood, CO 80111
Attention:  Secretary

        1. Exercise of Option. Effective as of today, ___________, 19__, the
undersigned ("Optionee") hereby elects to exercise Optionee's option to purchase
_________ shares of the Common Stock (the "Shares") of XCARE.NET, INC. (the
"Company") under and pursuant to the 1997 Stock Plan (the "Plan") and the Stock
Option Agreement dated <<Grant_Date>> (the "Option Agreement").

        2. Delivery of Payment. Purchaser herewith delivers to the Company the
full purchase price of the Shares, as set forth in the Option Agreement.

        3. Representations of Optionee. Optionee acknowledges that Optionee has
received, read and understood the Plan and the Option Agreement and agrees to
abide by and be bound by their terms and conditions.

        4. Rights as Shareholder. Until the issuance of the Shares (as evidenced
by the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company), no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. The Shares shall be issued to the
Optionee as soon as practicable after the Option is exercised. No adjustment
shall be made for a dividend or other right for which the record date is prior
to the date of issuance except as provided in Section 12 of the Plan.

        5. Company's Right of First Refusal. Before any Shares held by Optionee
or any transferee (either being sometimes referred to herein as the "Holder")
may be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this Section (the
"Right of First Refusal").

                (a) Notice of Proposed Transfer. The Holder of the Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
bona fide intention to sell or otherwise transfer such Shares; (ii) the name of
each proposed purchaser or other transferee ("Proposed Transferee"); (iii) the
number of Shares to be transferred to each Proposed Transferee; and (iv) the
bona fide cash price or other consideration for which the Holder proposes to
transfer the


<PAGE>   18

Shares (the "Offered Price"), and the Holder shall offer the Shares at the
Offered Price to the Company or its assignee(s).

                (b) Exercise of Right of First Refusal. At any time within
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less
than all, of the Shares proposed to be transferred to any one or more of the
Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below.

                (c) Purchase Price. The purchase price ("Purchase Price") for
the Shares purchased by the Company or its assignee(s) under this Section shall
be the Offered Price. If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

                (d) Payment. Payment of the Purchase Price shall be made, at the
option of the Company or its assignee(s), in cash (by check), by cancellation of
all or a portion of any outstanding indebtedness of the Holder to the Company
(or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within 30 days after receipt of the Notice or in the manner
and at the times set forth in the Notice.

                (e) Holder's Right to Transfer. If all of the Shares proposed in
the Notice to be transferred to a given Proposed Transferee are not purchased by
the Company and/or its assignee(s) as provided in this Section, then the Holder
may sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within 120 days after the date of the Notice, that any such sale or
other transfer is effected in accordance with any applicable securities laws and
that the Proposed Transferee agrees in writing that the provisions of this
Section shall continue to apply to the Shares in the hands of such Proposed
Transferee. If the Shares described in the Notice are not transferred to the
Proposed Transferee within such period, a new Notice shall be given to the
Company, and the Company and/or its assignees shall again be offered the Right
of First Refusal before any Shares held by the Holder may be sold or otherwise
transferred.

                (f) Exception for Certain Family Transfers. Anything to the
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Optionee's lifetime or on the Optionee's death by will
or intestacy to the Optionee's immediate family or a trust for the benefit of
the Optionee's immediate family shall be exempt from the provisions of this
Section. "Immediate Family" as used herein shall mean spouse, lineal descendant
or antecedent, father, mother, brother or sister. In such case, the transferee
or other recipient shall receive and hold the Shares so transferred subject to
the provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

                (g) Termination of Right of First Refusal. The Right of First
Refusal shall terminate as to any Shares upon the first sale of Common Stock of
the Company to the general public pursuant to a registration statement filed
with and declared effective by the Securities and Exchange Commission under the
Securities Act of 1933, as amended.

        6. Tax Consultation. Optionee understands that Optionee may suffer
adverse tax consequences as a result of Optionee's purchase or disposition of
the Shares. Optionee represents that Optionee has consulted with any tax
consultants Optionee deems advisable in connection with the purchase or
disposition of the Shares and that Optionee is not relying on the Company for
any tax advice.

        7. Restrictive Legends and Stop-Transfer Orders.

                (a) Legends. Optionee understands and agrees that the Company
shall cause the legends set forth below or legends substantially equivalent
thereto, to be placed upon any certificate(s) evidencing ownership of the Shares
together with any other legends that may be required by the Company or by state
or federal securities laws:

                THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
                THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
                SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS
                AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY
                COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH
                OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN
                COMPLIANCE THEREWITH.

                THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL
                HELD BY THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE
                EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF
                THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL
                OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT OF
                FIRST REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES.

                (b) Stop-Transfer Notices. Optionee agrees that, in order to
ensure compliance with the restrictions referred to herein, the Company may
issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

                (c) Refusal to Transfer. The Company shall not be required (i)
to transfer on its books any Shares that have been sold or otherwise transferred
in violation of any of the provisions of this Agreement or (ii) to treat as
owner of such Shares or to accord the right to vote or pay dividends to any
purchaser or other transferee to whom such Shares shall have been so
transferred.

        8. Successors and Assigns. The Company may assign any of its rights
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company. Subject to
the restrictions on transfer herein set forth, this


                                      -3-

administrators, successors and assigns.

        9. Interpretation. Any dispute regarding the interpretation of this
Agreement shall be submitted by Optionee or by the Company forthwith to the
Administrator which shall review such dispute at its next regular meeting. The
resolution of such a dispute by the Administrator shall be final and binding on
all parties.

        10. Governing Law; Severability. This Agreement is governed by the
internal substantive laws but not the choice of law rules, of New Mexico.

        11. Entire Agreement. The Plan and Option Agreement are incorporated
herein by reference. This Agreement, the Plan, the Option Agreement and the
Investment Representation Statement constitute the entire agreement of the
parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Optionee with
respect to the subject matter hereof, and may not be modified adversely to the
Optionee's interest except by means of a writing signed by the Company and
Optionee.

OPTIONEE:                    <<Name>>

SECURITY:                    COMMON STOCK

AMOUNT:

DATE:
</TABLE>

        In connection with the purchase of the above-listed Securities, the
undersigned Optionee represents to the Company the following:

        (a) Optionee is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities. Optionee is
acquiring these Securities for investment for Optionee's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

        (b) Optionee acknowledges and understands that the Securities constitute
"restricted securities" under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Optionee's
investment intent as expressed herein. In this connection, Optionee understands
that, in the view of the Securities and Exchange Commission, the statutory basis
for such exemption may be unavailable if Optionee's representation was
predicated solely upon a present intention to hold these Securities for the
minimum capital gains period specified under tax statutes, for a deferred sale,
for or until an increase or decrease in the market price of the Securities, or
for a period of one year or any other fixed period in the future. Optionee
further understands that the Securities must be held indefinitely unless they
are subsequently registered under the Securities Act or an exemption from such
registration is available. Optionee further acknowledges and understands that
the Company is under no obligation to register the Securities. Optionee
understands that the certificate evidencing the Securities will be imprinted
with a legend which prohibits the transfer of the Securities unless they are
registered or such registration is not required in the opinion of counsel
satisfactory to the Company and any other legend required under applicable state
securities laws.

        (c) Optionee is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the


<PAGE>   22

satisfaction of certain conditions. Rule 701 provides that if the issuer
qualifies under Rule 701 at the time of the grant of the Option to the Optionee,
the exercise will be exempt from registration under the Securities Act. In the
event the Company becomes subject to the reporting requirements of Section 13 or
15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or
such longer period as any market stand-off agreement may require) the Securities
exempt under Rule 701 may be resold, subject to the satisfaction of certain of
the conditions specified by Rule 144, including: (1) the resale being made
through a broker in an unsolicited "broker's transaction" or in transactions
directly with a market maker (as said term is defined under the Securities
Exchange Act of 1934); and, in the case of an affiliate, (2) the availability of
certain public information about the Company, (3) the amount of Securities being
sold during any three month period not exceeding the limitations specified in
Rule 144(e), and (4) the timely filing of a Form 144, if applicable.

        In the event that the Company does not qualify under Rule 701 at the
time of grant of the Option, then the Securities may be resold in certain
limited circumstances subject to the provisions of Rule 144, which requires the
resale to occur not less than two years after the later of the date the
Securities were sold by the Company or the date the Securities were sold by an
affiliate of the Company, within the meaning of Rule 144; and, in the case of
acquisition of the Securities by an affiliate, or by a non-affiliate who
subsequently holds the Securities less than three years, the satisfaction of the
conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.

        (d) Optionee further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Optionee understands that no assurances can be given that any
such other registration exemption will be available in such event.

such other source as the Board deems reliable;

               (ii) If the Common Stock is regularly quoted by a recognized

the date prior to the purchase, as reported in The Wall Street Journal or such
other source as the Board deems reliable;

               (iii) In the absence of an established market for the Common
Stock, the Fair Market Value thereof shall be determined in good faith by the
Board; or

               (iv) For purposes of the Enrollment Date of the first Offering
Period under the Plan, the Fair Market Value shall be the initial price to the
public as set forth in the final prospectus included within the registration

is lower; provided however, that the Purchase Price may be adjusted by the Board
pursuant to Section 20.

covered by each option under the Plan which have not yet been exercised and the
number of shares of Common Stock which have been authorized for issuance under
the Plan but not yet placed under option.

          (p)  "Subsidiary" shall mean a corporation, domestic or foreign, of

          (b)  Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan (i) to the extent that,
immediately after the grant, such Employee (or any other person whose stock
would be attributed to such Employee pursuant to Section 424(d) of the Code)
would own capital stock of the Company and/or hold outstanding options to
purchase such stock possessing five percent (5%) or more of the total combined
voting power or value of all classes of the capital stock of the Company or of

     4.   Offering Periods. The Plan shall be implemented by consecutive,
overlapping Offering Periods with a new Offering Period commencing on the first
Trading Day on or after May 1 and November 1 each year, or on such other date as
the Board shall determine, and continuing thereafter until terminated in
accordance with Section 20 hereof; provided, however, that the first Offering
Period under the Plan shall commence with the first Trading Day on or after the
date on which the Securities and Exchange Commission declares the Company's
Registration Statement effective and ending on the last Trading Day on or before
April 30, 2001. The Board shall have the power to change the duration of
Offering Periods (including the commencement dates thereof) with respect to
future offerings without shareholder approval if such change is announced at
least five (5) days prior to the scheduled beginning of the first Offering
Period to be affected thereafter.

     5.   Participation.

          (a)  An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office
fifteen days prior to the applicable Enrollment Date.

          (b)  Payroll deductions for a participant shall commence on the first
payroll following the Enrollment Date and shall end on the last payroll in the
Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.

     6.   Payroll Deductions.

          (a)  At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount


                                       3
<PAGE>   4

not exceeding twenty percent (20%) of the Compensation which he or she receives
on each pay day during the Offering Period.

          (b)  All payroll deductions made for a participant shall be credited
to his or her account under the Plan and shall be withheld in whole percentages
only. A participant may not make any additional payments into such account.

          (c)  A participant may discontinue his or her participation in the
Plan as provided in Section 10 hereof, or may increase or decrease the rate of
his or her payroll deductions during the Offering Period by completing or filing
with the Company a new subscription agreement authorizing a change in payroll
deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

          (d)  Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's
payroll deductions may be decreased to zero percent (0%) at any time during a
Purchase Period. Payroll deductions shall recommence at the rate provided in
such participant's subscription agreement at the beginning of the first Purchase
Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10 hereof.

          (e)  At the time the option is exercised, in whole or in part, or at
the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

     7.   Grant of Option. On the Enrollment Date of each Offering Period, each
eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Purchase Period more than
20,000 shares of the Company's Common Stock (subject to any adjustment pursuant
to Section 19), and provided further that such purchase shall be subject to the
limitations set forth in Sections 3(b) and 12 hereof. The Board may, for future
Offering Periods, increase or decrease, in its absolute discretion, the maximum
number of shares of the Company's Common Stock an Employee may purchase during
each Purchase Period of such Offering Period. Exercise of the option shall occur
as provided in Section 8 hereof, unless the

                                       4
<PAGE>   5

participant has withdrawn pursuant to Section 10 hereof. The option shall expire
on the last day of the Offering Period.

     8.   Exercise of Option.

          (a)  Unless a participant withdraws from the Plan as provided in
Section 10 hereof, his or her option for the purchase of shares shall be
exercised automatically on the Exercise Date, and the maximum number of full
shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to purchase
shares hereunder is exercisable only by him or her.

          (b)  If the Board determines that, on a given Exercise Date, the
number of shares with respect to which options are to be exercised may exceed
(i) the number of shares of Common Stock that were available for sale under the
Plan on the Enrollment Date of the applicable Offering Period, or (ii) the
number of shares available for sale under the Plan on such Exercise Date, the
Board may in its sole discretion (x) provide that the Company shall make a pro
rata allocation of the shares of Common Stock available for purchase on such
Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall
be practicable and as it shall determine in its sole discretion to be equitable
among all participants exercising options to purchase Common Stock on such
Exercise Date, and continue all Offering Periods then in effect, or (y) provide
that the Company shall make a pro rata allocation of the shares available for
purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform
a manner as shall be practicable and as it shall determine in its sole
discretion to be equitable among all participants exercising options to purchase
Common Stock on such Exercise Date, and terminate any or all Offering Periods
then in effect pursuant to Section 20 hereof. The Company may make pro rata
allocation of the shares available on the Enrollment Date of any applicable
Offering Period pursuant to the preceding sentence, notwithstanding any
authorization of additional shares for issuance under the Plan by the Company's
shareholders subsequent to such Enrollment Date.

     9.   Delivery. As promptly as practicable after each Exercise Date on which
a purchase of shares occurs, the Company shall arrange the delivery to each
participant, as appropriate, of a certificate representing the shares purchased
upon exercise of his or her option.

     10.  Withdrawal.

          (a)  A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by giving written notice to the Company in
the form of Exhibit B to this Plan. All of the participant's payroll deductions
credited to his or her account shall be paid to such participant promptly after
receipt of notice of withdrawal and such participant's option for the Offering
Period


                                       5
<PAGE>   6

shall be automatically terminated, and no further payroll deductions for the
purchase of shares shall be made for such Offering Period. If a participant
withdraws from an Offering Period, payroll deductions shall not resume at the
beginning of the succeeding Offering Period unless the participant delivers to
the Company a new subscription agreement.

          (b)  A participant's withdrawal from an Offering Period shall not have
any effect upon his or her eligibility to participate in any similar plan which
may hereafter be adopted by the Company or in succeeding Offering Periods which
commence after the termination of the Offering Period from which the participant
withdraws.

     11.  Termination of Employment.

         Upon a participant's ceasing to be an Employee, for any reason, he or
she shall be deemed to have elected to withdraw from the Plan and the payroll
deductions credited to such participant's account during the Offering Period but
not yet used to exercise the option shall be returned to such participant or, in
the case of his or her death, to the person or persons entitled thereto under
Section 15 hereof, and such participant's option shall be automatically
terminated. The preceding sentence notwithstanding, a participant who receives
payment in lieu of notice of termination of employment shall be treated as
continuing to be an Employee for the participant's customary number of hours per
week of employment during the period in which the participant is subject to such
payment in lieu of notice.

     12.  Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan.

     13.  Stock.

          (a)  Subject to adjustment upon changes in capitalization of the
Company as provided in Section 19 hereof, the maximum number of shares of the
Company's Common Stock which shall be made available for sale under the Plan
shall be 3,500,000 shares, plus an annual increase to be added on January 1, of
each year, beginning in 2001, equal to the lesser of (i) 3,500,000 shares, (ii)
2% of the outstanding shares on such date, or (iii) a lesser amount determined
by the Board.

          (b)  The participant shall have no interest or voting right in shares
covered by his option until such option has been exercised.

          (c)  Shares to be delivered to a participant under the Plan shall be
registered in the name of the participant or in the name of the participant and
his or her spouse.

     14.  Administration. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

     15.  Designation of Beneficiary.

                                       6
<PAGE>   7

          (a)  A participant may file a written designation of a beneficiary who
is to receive any shares and cash, if any, from the participant's account under
the Plan in the event of such participant's death subsequent to an Exercise Date
on which the option is exercised but prior to delivery to such participant of
such shares and cash. In addition, a participant may file a written designation
of a beneficiary who is to receive any cash from the participant's account under
the Plan in the event of such participant's death prior to exercise of the
option. If a participant is married and the designated beneficiary is not the
spouse, spousal consent shall be required for such designation to be effective.

          (b)  Such designation of beneficiary may be changed by the participant
at any time by written notice. In the event of the death of a participant and in
the absence of a beneficiary validly designated under the Plan who is living at
the time of such participant's death, the Company shall deliver such shares
and/or cash to the executor or administrator of the estate of the participant,
or if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such shares and/or
cash to the spouse or to any one or more dependents or relatives of the
participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.

     16.  Transferability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

     17.  Use of Funds. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

     18.  Reports. Individual accounts shall be maintained for each participant
in the Plan. Statements of account shall be given to participating Employees at
least annually, which statements shall set forth the amounts of payroll
deductions, the Purchase Price, the number of shares purchased and the remaining
cash balance, if any.

     19.  Adjustments Upon Changes in Capitalization, Dissolution, Liquidation,
Merger or Asset Sale.

          (a)  Changes in Capitalization. Subject to any required action by the
shareholders of the Company, the Reserves, the maximum number of shares each
participant may purchase each Purchase Period (pursuant to Section 7), as well
as the price per share and the number of shares of Common Stock covered by each
option under the Plan which has not yet been exercised shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without

                                       7
<PAGE>   8

receipt of consideration." Such adjustment shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. Except as
expressly provided herein, no issuance by the Company of shares of stock of any
class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason thereof shall be made with respect to, the
number or price of shares of Common Stock subject to an option.

          (b)  Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Offering Period then in progress
shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and
shall terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the Board. The New
Exercise Date shall be before the date of the Company's proposed dissolution or
liquidation. The Board shall notify each participant in writing, at least ten
(10) business days prior to the New Exercise Date, that the Exercise Date for
the participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

          (c)  Merger or Asset Sale. In the event of a proposed sale of all or
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the option, any Purchase Periods
then in progress shall be shortened by setting a new Exercise Date (the "New
Exercise Date") and any Offering Periods then in progress shall end on the New
Exercise Date. The New Exercise Date shall be before the date of the Company's
proposed sale or merger. The Board shall notify each participant in writing, at
least ten (10) business days prior to the New Exercise Date, that the Exercise
Date for the participant's option has been changed to the New Exercise Date and
that the participant's option shall be exercised automatically on the New
Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

     20.  Amendment or Termination.

          (a)  The Board of Directors of the Company may at any time and for any
reason terminate or amend the Plan. Except as provided in Section 19 hereof, no
such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Offering Period or the Plan
is in the best interests of the Company and its shareholders. Except as provided
in Section 19 and this Section 20 hereof, no amendment may make any change in
any option theretofore granted which adversely affects the rights of any
participant. To the extent necessary to comply with Section 423 of the Code (or
any successor rule or provision or any other applicable law, regulation or stock
exchange rule), the Company shall obtain shareholder approval in such a manner
and to such a degree as required.

          (b)  Without shareholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be


                                       8
<PAGE>   9

entitled to change the Offering Periods, limit the frequency and/or number of
changes in the amount withheld during an Offering Period, establish the exchange
ratio applicable to amounts withheld in a currency other than U.S. dollars,
permit payroll withholding in excess of the amount designated by a participant
in order to adjust for delays or mistakes in the Company's processing of
properly completed withholding elections, establish reasonable waiting and
adjustment periods and/or accounting and crediting procedures to ensure that
amounts applied toward the purchase of Common Stock for each participant
properly correspond with amounts withheld from the participant's Compensation,
and establish such other limitations or procedures as the Board (or its
committee) determines in its sole discretion advisable which are consistent with
the Plan.

          (c)  In the event the Board determines that the ongoing operation of
the Plan may result in unfavorable financial accounting consequences, the Board
may, in its discretion and, to the extent necessary or desirable, modify or
amend the Plan to reduce or eliminate such accounting consequence including, but
not limited to:

               (i)  altering the Purchase Price for any Offering Period
including an Offering Period underway at the time of the change in Purchase
Price;

               (ii) shortening any Offering Period so that Offering Period ends
on a new Exercise Date, including an Offering Period underway at the time of the
Board action; and

               (iii) allocating shares.

     Such modifications or amendments shall not require stockholder approval or
the consent of any Plan participants.

     21.  Notices. All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

     22.  Conditions Upon Issuance of Shares. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

     As a condition to the exercise of an option, the Company may require the
person exercising such option to represent and warrant at the time of any such
exercise that the shares are being purchased only for investment and without any
present intention to sell or distribute such shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law.

                                       9
<PAGE>   10

     23.  Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 20 hereof.

     24.  Automatic Transfer to Low Price Offering Period. To the extent
permitted by any applicable laws, regulations, or stock exchange rules if the
Fair Market Value of the Common Stock on any Exercise Date in an Offering Period
is lower than the Fair Market Value of the Common Stock on the Enrollment Date
of such Offering Period, then all participants in such Offering Period shall be
automatically withdrawn from such Offering Period immediately after the exercise
of their option on such Exercise Date and automatically re-enrolled in the
immediately following Offering Period as of the first day thereof.

                             SUBSCRIPTION AGREEMENT

_____ Original Application                          Enrollment Date: ___________

_____ Change in Payroll Deduction Rate

_____ Change of Beneficiary(ies)

1.   ____________________ hereby elects to participate in the XCare.net, Inc.
     1999 Employee Stock Purchase Plan (the "Employee Stock Purchase Plan") and
     subscribes to purchase shares of the Company's Common Stock in accordance
     with this Subscription Agreement and the Employee Stock Purchase Plan.

2.   I hereby authorize payroll deductions from each paycheck in the amount of
     ____% of my Compensation on each payday (from 1% to 20%) during the
     Offering Period in accordance with the Employee Stock Purchase Plan.
     (Please note that no fractional percentages are permitted.)

3.   I understand that said payroll deductions shall be accumulated for the
     purchase of shares of Common Stock at the applicable Purchase Price
     determined in accordance with the Employee Stock Purchase Plan. I
     understand that if I do not withdraw from an Offering Period, any
     accumulated payroll deductions will be used to automatically exercise my
     option.

4.   I have received a copy of the complete Employee Stock Purchase Plan. I
     understand that my participation in the Employee Stock Purchase Plan is in
     all respects subject to the terms of the Plan. I understand that my ability
     to exercise the option under this Subscription Agreement is subject to
     shareholder approval of the Employee Stock Purchase Plan.

5.   Shares purchased for me under the Employee Stock Purchase Plan should be
     issued in the name(s) of (Employee or Employee and Spouse only).

6.   I understand that if I dispose of any shares received by me pursuant to the
     Plan within 2 years after the Enrollment Date (the first day of the
     Offering Period during which I purchased such shares) or one year after the
     Exercise Date, I will be treated for federal income tax purposes as having
     received ordinary income at the time of such disposition in an amount equal
     to the excess of the fair market value of the shares at the time such
     shares were purchased by me over the price which I paid for the shares. I
     hereby agree to notify the Company in writing

<PAGE>   12

     within 30 days after the date of any disposition of my shares and I will
     make adequate provision for Federal, state or other tax withholding
     obligations, if any, which arise upon the disposition of the Common Stock.
     The Company may, but will not be obligated to, withhold from my
     compensation the amount necessary to meet any applicable withholding
     obligation including any withholding necessary to make available to the
     Company any tax deductions or benefits attributable to sale or early
     disposition of Common Stock by me. If I dispose of such shares at any time
     after the expiration of the 2-year and 1-year holding periods, I understand
     that I will be treated for federal income tax purposes as having received
     income only at the time of such disposition, and that such income will be
     taxed as ordinary income only to the extent of an amount equal to the
     lesser of (1) the excess of the fair market value of the shares at the time
     of such disposition over the purchase price which I paid for the shares, or
     (2) 15% of the fair market value of the shares on the first day of the
     Offering Period. The remainder of the gain, if any, recognized on such
     disposition will be taxed as capital gain.

7.   I hereby agree to be bound by the terms of the Employee Stock Purchase
     Plan. The effectiveness of this Subscription Agreement is dependent upon my
     eligibility to participate in the Employee Stock Purchase Plan.

8.   In the event of my death, I hereby designate the following as my
     beneficiary(ies) to receive all payments and shares due me under the
     Employee Stock Purchase Plan:

               (i)  No person shall have any discretion to select which Outside
Directors shall be granted Options or to determine the number of Shares to be
covered by Options.

               (ii) Each Outside Director shall be automatically granted an
Option to purchase 175,000 Shares (the "First Option") on the date on which the
later of the following events occurs: (A) the IPO Effective Date, or (B) the
date on which such person first becomes an Outside Director, whether through
election by the shareholders of the Company or appointment by the Board to fill
a vacancy; provided, however, that an Inside Director who ceases to be an Inside
Director but who remains a Director shall not receive a First Option.

               (iii) Each Outside Director shall be automatically granted an
Option to purchase 70,000 Shares (a "Subsequent Option") on the date of the
annual stockholders meeting of each year provided he or she is then an Outside
Director and if as of such date, he or she shall have served on the Board for at
least the preceding six (6) months.

               (iv) Notwithstanding the provisions of subsections (ii) and (iii)
hereof, any exercise of an Option granted before the Company has obtained
shareholder approval of the Plan in accordance with Section 16 hereof shall be
conditioned upon obtaining such shareholder approval of the Plan in accordance
with Section 16 hereof.

               (v)  The terms of a First Option granted hereunder shall be as
follows:

                    (A)  the term of the First Option shall be ten (10) years.

                    (B)  the First Option shall be exercisable only while the
Outside Director remains a Director of the Company, except as set forth in
Sections 8 and 10 hereof.

                    (C)  the exercise price per Share shall be 100% of the Fair
Market Value per Share on the date of grant of the First Option.

                    (D)  subject to Section 10 hereof, the First Option shall

to serve as a Director on such dates.

               (vi) The terms of a Subsequent Option granted hereunder shall be

<PAGE>   4

                    (D)  subject to Section 10 hereof, the Subsequent Option
shall become exercisable as to 100% percent of the Shares subject to the
Subsequent Option on the anniversary of its date of grant, provided that the
Optionee continues to serve as a Director on such date.

               (vii) In the event that any Option granted under the Plan would
cause the number of Shares subject to outstanding Options plus the number of
Shares previously purchased under Options to exceed the Pool, then the remaining
Shares available for Option grant shall be granted under Options to the Outside
Directors on a pro rata basis. No further grants shall be made until such time,
if any, as additional Shares become available for grant under the Plan through
action of the Board or the shareholders to increase the number of Shares which
may be issued under the Plan or through cancellation or expiration of Options
previously granted hereunder.

     5.   Eligibility. Options may be granted only to Outside Directors. All
Options shall be automatically granted in accordance with the terms set forth in
Section 4 hereof.

          The Plan shall not confer upon any Optionee any right with respect to
continuation of service as a Director or nomination to serve as a Director, nor
shall it interfere in any way with any rights which the Director or the Company
may have to terminate the Director's relationship with the Company at any time.

     6.   Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board or its approval by the shareholders of the
Company as described in Section 16 of the Plan. It shall continue in effect for
a term of ten (10) years unless sooner terminated under Section 11 of the Plan.

     7.   Form of Consideration. The consideration to be paid for the Shares to
be issued upon exercise of an Option, including the method of payment, shall
consist of (i) cash, (ii) check, (iii) other shares which (x) in the case of
Shares acquired upon exercise of an option, have been owned by the Optionee for
more than six (6) months on the date of surrender, and (y) have a Fair Market
Value on the date of surrender equal to the aggregate exercise price of the
Shares as to which said Option shall be exercised, (iv) consideration received
by the Company under a cashless exercise program implemented by the Company in
connection with the Plan, or (v) any combination of the foregoing methods of
payment.

     8.   Exercise of Option.

          (a)  Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable at such times as are set forth in Section
4 hereof; provided, however, that no Options shall be exercisable until
shareholder approval of the Plan in accordance with Section 16 hereof has been
obtained.

               An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Option by the person

                                      -4-
<PAGE>   5

entitled to exercise the Option and full payment for the Shares with respect to
which the Option is exercised has been received by the Company. Full payment may
consist of any consideration and method of payment allowable under Section 7 of
the Plan. Until the issuance (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company) of the
stock certificate evidencing such Shares, no right to vote or receive dividends
or any other rights as a shareholder shall exist with respect to the Optioned
Stock, notwithstanding the exercise of the Option. A share certificate for the
number of Shares so acquired shall be issued to the Optionee as soon as
practicable after exercise of the Option. No adjustment shall be made for a
dividend or other right for which the record date is prior to the date the stock
certificate is issued, except as provided in Section 10 of the Plan.

               Exercise of an Option in any manner shall result in a decrease in
the number of Shares which thereafter may be available, both for purposes of
the Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

          (b)  Termination of Continuous Status as a Director. Subject to
Section 10 hereof, in the event an Optionee's status as a Director terminates
(other than upon the Optionee's death or Disability), the Optionee may exercise
his or her Option, but only within three (3) months following the date of such
termination, and only to the extent that the Optionee was entitled to exercise
it on the date of such termination (but in no event later than the expiration of
its ten (10) year term). To the extent that the Optionee was not entitled to
exercise an Option on the date of such termination, and to the extent that the
Optionee does not exercise such Option (to the extent otherwise so entitled)
within the time specified herein, the Option shall terminate.

          (c)  Disability of Optionee. In the event Optionee's status as a
Director terminates as a result of Disability, the Optionee may exercise his or
her Option, but only within twelve (12) months following the date of such
termination, and only to the extent that the Optionee was entitled to exercise
it on the date of such termination (but in no event later than the expiration of
its ten (10) year term). To the extent that the Optionee was not entitled to
exercise an Option on the date of termination, or if he or she does not exercise
such Option (to the extent otherwise so entitled) within the time specified
herein, the Option shall terminate.

          (d)  Death of Optionee. In the event of an Optionee's death, the
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance may exercise the Option, but only within twelve (12)
months following the date of death, and only to the extent that the Optionee was
entitled to exercise it on the date of death (but in no event later than the
expiration of its ten (10) year term). To the extent that the Optionee was not
entitled to exercise an Option on the date of death, and to the extent that the
Optionee's estate or a person who acquired the right to exercise such Option
does not exercise such Option (to the extent otherwise so entitled) within the
time specified herein, the Option shall terminate.

     9.   Non-Transferability of Options. The Option may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

     10.  Adjustments Upon Changes in Capitalization, Dissolution, Merger or
Asset Sale.

          (a)  Changes in Capitalization. Subject to any required action by the
shareholders of the Company, the number of Shares covered by each outstanding
Option, the number of Shares which have been authorized for issuance under the
Plan but as to which no Options have yet been granted or which have been
returned to the Plan upon cancellation or expiration of an Option, as well as
the price per Share covered by each such outstanding Option, and the number of
Shares issuable pursuant to the automatic grant provisions of Section 4 hereof
shall be proportionately adjusted for any increase or decrease in the number of
issued Shares resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued Shares effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of Shares
subject to an Option.

          (b)  Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, to the extent that an Option has not
been previously exercised, it shall terminate immediately prior to the
consummation of such proposed action.

          (c)  Merger or Asset Sale. In the event of a merger of the Company
with or into another corporation or the sale of substantially all of the assets
of the Company, outstanding Options may be assumed or equivalent options may be
substituted by the successor corporation or a Parent or Subsidiary thereof (the
"Successor Corporation"). If an Option is assumed or substituted for, the Option
or equivalent option shall continue to be exercisable as provided in Section 4
hereof for so long as the Optionee serves as a Director or a director of the
Successor Corporation. Following such assumption or substitution, if the
Optionee's status as a Director or director of the Successor Corporation, as
applicable, is terminated other than upon a voluntary resignation by the
Optionee, the Option or option shall become fully exercisable, including as to
Shares for which it would not otherwise be exercisable. Thereafter, the Option
or option shall remain exercisable in accordance with Sections 8(b) through (d)
above.

     If the Successor Corporation does not assume an outstanding Option or
substitute for it an equivalent option, the Option shall become fully vested and
exercisable, including as to Shares for which it would not otherwise be
exercisable. In such event the Board shall notify the Optionee that the Option
shall be fully exercisable for a period of thirty (30) days from the date of
such notice, and upon the expiration of such period the Option shall terminate.

     For the purposes of this Section 10(c), an Option shall be considered
assumed if, following the merger or sale of assets, the Option confers the right
to purchase or receive, for each Share of Optioned Stock subject to the Option
immediately prior to the merger or sale of assets, the consideration (whether
stock, cash, or other securities or property) received in the merger or sale of
assets by holders of Common Stock for each Share held on the effective date of
the transaction (and

                                      -6-
<PAGE>   7

if holders were offered a choice of consideration, the type of consideration
chosen by the holders of a majority of the outstanding Shares). If such
consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option, for each Share of Optioned Stock
subject to the Option, to be solely common stock of the successor corporation or
its Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.

     11.  Amendment and Termination of the Plan.

          (a)  Amendment and Termination. The Board may at any time amend,
alter, suspend, or discontinue the Plan, but no amendment, alteration,
suspension, or discontinuation shall be made which would impair the rights of
any Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with any applicable
law, regulation or stock exchange rule, the Company shall obtain shareholder
approval of any Plan amendment in such a manner and to such a degree as
required.

          (b)  Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated.

     12.  Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date determined in accordance with Section 4 hereof.

     13.  Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, state securities laws, and the requirements of any stock exchange
upon which the Shares may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

          As a condition to the exercise of an Option, the Company may require
the person exercising such Option to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares, if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

          Inability of the Company to obtain authority from any regulatory body
having jurisdiction, which authority is deemed by the Company's counsel to be
necessary to the lawful issuance and sale of any Shares hereunder, shall relieve
the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained.

                                      -7-

     14.  Reservation of Shares. The Company, during the term of this Plan, will
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     15.  Option Agreement. Options shall be evidenced by written option
agreements in such form as the Board shall approve.

     16.  Shareholder Approval. The Plan shall be subject to approval by the
shareholders of the Company within twelve (12) months after the date the Plan is
adopted. Such shareholder approval shall be obtained in the degree and manner
required under applicable state and federal law and any stock exchange rules.

         (30) days, if the breaching party fails to proceed promptly after being
         given such notice to commence remedying the breach and thereafter to
         proceed to remedy the same, the other party shall have the right to
         terminate this Agreement, provided such party gives the breaching party
         thirty (30) days' prior written notice to that effect. Notwithstanding
         the foregoing, either party shall have the fight to immediately
         terminate this Agreement upon any breach by the other of its
         obligations under Section II above.

         Termination of this Agreement shall be without prejudice to all accrued
         rights and remedies either party may have and shall not affect any

VII.     FORCE MAJEURE

         of God, acts of war, rites, strikes, lightning, floods, epidemics,

         required and has a .responsibility to understand such data variables,

         unless Customer specifically requests MPOWER to perform these tasks at
         agreed upon rates specified in a Work Order.

         B.    Customer Data

         Customer shall be responsible for inputting and ensuring the accuracy,

         determining how many and on what print stock such outputs are to be
         printed or into which files or programs on Customer-controlled
         computers such files are to be downloaded and manipulated, at
         Customer's own initiative, responsibility and risk. Customer hereby
         acknowledges 'responsibility for generally

         controlling all aspects related to the production, distribution and
         control of such outputs. Customer further acknowledges that,
         notwithstanding the responsibility of MPOWER to have used due care and
         diligence in the design, programming, documentation and operation of
         the System, the accuracy of Customer's data base within MPOWER(R) and
         the accuracy of the several outputs of the MPOWER(R), including but not
         limited to, outputs that control the billing, receipt or expenditure of
         monies, will be dependent on the accuracy and use of the data
         variables, logic rules, system functions and Customer data input into
         MPOWER(R) by Customer and verified by Customer.

         MPOWER agrees to defend, indemnify and hold Customer harmless against

         provided that MPOWER shall have received timely written notice of any
         such claim and that MPOWER shall have sole control of the defense of
         such claim and all negotiations for the settlement or compromise of
         such claim.





MPOWER MASTER AGREEMENT                                                  PAGE 13

<PAGE>   14

         As of the date first written above, MPOWER warrants that it is not
         aware of any infringement, and has not been notified by any third party
         that it may be infringing, any U. S. Letter Patent, copyright, trade
         secret or the proprietary rights of others.

         If use of an MPOWER Product by Customer is enjoined, or becomes, or, in
         MPOWER's sole opinion, is likely to become, the subject of a claim of
         infringement, MPOWER will, at its option and expense, either:

         1.    procure for Customer the right to continue using the MPOWER
               Product in question; or

         2.    replace or modify the same so that it is functionally equivalent
               [i.e. the MPOWER Product will achieve the same or similar
               business logic result] (or contains more functionality) and is
               non-infringing.

         Notwithstanding the foregoing, if MPOWER determines that neither of the
         alternatives set forth above is reasonably available, MPOWER will
         refund to Customer any un-amortized portion of the infringing MPOWER
         Product's license fee which has then been paid by Customer.
         Amortization shall be based upon a seven (7)-year life of the
         infringing MPOWER Product, beginning on the date the infringing MPOWER
         Product was licensed by Customer from MPOWER. Should such refund occur,
         Customer agrees to return the infringing MPOWER Product to MPOWER.

         Should any refund described above occur, the license for the infringing
         MPOWER Product shall be terminated and MPOWER, its affiliates,
         subsidiaries, assigns and successor corporations shall be released from
         any and all liability arising from any and all claims, losses,
         liabilities, damages, costs or deficiencies which are then-existing or
         which may arise in the future with regard to such infringing MPOWER
         Product(s) for which MPOWER has refunded fees pursuant to this Section
         X.

         Notwithstanding anything contained herein to the contrary, MPOWER shall
         have no liability for any loss, cost, claim or expense caused by:

         1.    alteration of any MPOWER Product provided hereunder by any party
               other than MPOWER;

         2.    any loss, expense or liability resulting from any infringement
               which is a consequence of MPOWER's compliance with designs or
               code submitted to MPOWER by Customer;

         3.    the use of any MPOWER Product in combination with products not
               licensed to customer by MPOWER;


MPOWER MASTER AGREEMENT                                                 PAGE  14

<PAGE>   15

         4.    continuation of the allegedly infringing activity by Customer
               after Customer is notified in writing thereof and after the
               conclusion of a reasonable grace period afforded Customer in the
               notice to migrate from the infringing activity to an alternate
               solution; or

         5.    Customer's use of an MPOWER Product other than in compliance with
               the terms and conditions of this Agreement.

         Notwithstanding the foregoing, MPOWER shall not be obligated to defend,
         indemnify or hold Customer harmless from and against any claim, suit
         proceeding or allegation asserted by a parent, subsidiary or affiliate
         of Customer.

         The foregoing remedy set forth in this Section X represents the
         exclusive remedy of Customer and MPOWER's sole liability with regard to
         any claim that an MPOWER Product infringes the rights of others.


XI.      RESOLUTION OF DISPUTES

         If any dispute shall arise between the parties under this Agreement,
         the parties shall make every effort to amicably resolve the dispute
         pursuant to this Section XI. The following procedures shall be adhered
         to in order to expeditiously resolve any disputes arising during the
         term of this Agreement.

         The party invoking the procedures of this Section XI shall provide
         written notice to the other party and within five (5) business days
         following the other party's receipt of such notice, the parties'
         implementation team leaders shall attempt to resolve such dispute. If
         the parties' team leaders do not resolve such dispute within seven (7)
         business days following the date of the non-invoking party's receipt of
         notice hereunder, either party hereto shall have the fight to refer
         such dispute for "Executive Review" as provided below.

         "Executive Review" shall refer to the dispute resolution process which
         shall be conducted as follows: within fifteen (15) days of any party's
         request for Executive Review, each such party shall have designated an
         executive-level employee of such party and such designated executive
         shall have met, either in person or via telephone, with the other
         party's executive-level designee to attempt to resolve such dispute. If
         said executive- level designees are unable to resolve the dispute
         within ten (10) business days of their first telephone or in-person
         meeting pursuant to this paragraph, either party may request that the
         dispute be referred to a second level of Executive Review. Within ten
         (10) days of any party's request for such second level of Executive
         Review, the Chief Executive Officers of both parties hereto shall meet,
         in person or via telephone, to attempt to settle such dispute.
         Notwithstanding anything in this Agreement to the contrary, should
         either party feel the dispute cannot be amicably resolved after having
         negotiated in good faith to

         resolve such dispute pursuant to the foregoing provisions of this
         Section XI, such party shall have the right to terminate such
         negotiations. Nothing in this Section XI shall require either party to
         engage in negotiations to resolve a dispute for a period of more than
         forty-five (45) days.

         area.

         Third Party Software: I agree not to copy or use MethodistCare and
         MPOWER licensed software in violation of any vendor license agreements
         or state/federal laws. Further, I agree not to remove any licensed
         software from or lead any unapproved software on MethodistCare and
         MPOWER computers or systems.

         (d)      to copy and use MPOWER Release on a substitute computer or
                  computers if the authorized computers become inoperable;

         (e)      to use MPOWER Release at Customer's third party disaster site
                  on a computer other than the authorized computers (including

         (f)      to use MPOWER Release as otherwise provided in this Agreement;

         (g)      to relocate the authorized computers to any Controlled
                  Customer facility; and

         (h)      to make a reasonable number of copies of the documentation
                  related to the MPOWER Release.


         All of such rights are collectively referred to as the "License
         Rights."

         Customer may extend the license for such single, Object Code instance
         of MPOWER(R) ("License Extension(s)") for [*] lives by paying MPOWER
         the fees for additional lives defined in Section VIII below, and
         abiding by the terms therein stipulated, and by providing the number of
         such additional lives to MPOWER prior to Customer's first use of
         MPOWER(R) on behalf of such additional lives.

         Customer may copy MPOWER(R) and/or the Documentation as allowed under
         Section III of the Master Agreement. Furthermore, Customer may copy the
         Documentation in order to supply a copy of the Documentation to each
         end user of MPOWER(R) at each Site. Customer agrees that any and all
         copies of MPOWER(R) and/or the Documentation made by Customer shall
         include any/all copyright and proprietary notices in the same form as
         contained on the original copy. Except as allowed in Section III of the
         Master Agreement and this paragraph, Customer may not otherwise make
         copies of MPOWER(R) or the Documentation or any part thereof without
         the prior written consent of MPOWER. Customer agrees there shall be no
         other use of MPOWER(R) or the Documentation without the prior written
         consent of MPOWER except as allowed in Section II of the Master
         Agreement.

         In order to ensure that MPOWER(R) is being used in conformity with the
         license being granted under this Attachment, MPOWER shall have the
         right to conduct audits (either on-site or remotely, at MPOWER's
         option) of Customer's use of MPOWER(R) at periodic intervals. MPOWER
         agrees that any such on-site audit shall be scheduled in advance and at
         a time so as not to unduly interfere with Customer's business
         operations. Customer agrees that any audit revealing unauthorized use
         of MPOWER(R) will result in Customer's being liable for the payment of
         additional fees to MPOWER equal to MPOWER's fees as stated in Section
         VIII A of this Attachment.

         Network and other Use. MPOWER acknowledges that the MPOWER Release will
         be operated in conjunction with, and as a component of the Customers
         network. As such, the MPOWER Release will be electronically linked to
         the software and equipment, with which it may interact, including
         interchanging data. The License Rights are deemed to include a license
         to use the MPOWER Release in conjunction with the Customer's network.
         Authorized Users may access the MPOWER Release through Customer's
         network, and that such access and use via Customer's network does not
         violate the License Rights.


III      DELIVERY AND MEDIA

         Promptly after the full execution of this Attachment, MPOWER will
         deliver to Customer:


         A. one (l) copy of the then-current Release of MPOWER(R) in Object Code
         form; and

         B. one (1) set of the the-current version of the Documentation in
         electronic form.

IV.      WARRANTY


         A. System Warranties

         Non-Infringement Warranty. MPOWER represents and warrants that as of
         the Effective Date the MPOWER Release's performance under this
         Agreement does not, and will continue not to, infringe, or constitute
         an infringement or misappropriation of, the intellectual property
         rights of any third party.

         Performance Warranty. MPOWER represents and warrants that MPOWER
         Release does, and shall continue to, meet or exceed the Functional
         Specifications, Technical Specifications and Performance Standards set
         forth in MPOWER's RFP responses, sales brochures and marketing
         materials which are incorporated herein and made a part of this
         Agreement. (the "Performance Warranty"). If MPOWER Release fails to
         meet any aspect of the Performance Warranty (irrespective of the
         severity of such failure) for any three consecutive months during the
         warranty period, then Customer shall have the right to terminate this
         Agreement pursuant. If MPOWER Release does not meet any aspect of the
         Performance Warranty after the expiration of the warranty period but
         while the Support and Maintenance Agreement is in effect, then MPOWER
         shall take whatever corrective actions as may be necessary (or as
         Customer may request) to have MPOWER Release meet the Performance
         Warranty, at Customer's sole cost and expense.


         PASS-THROUGH OF THIRD PARTY WARRANTIES. To the extent MPOWER may do so
         under




MPOWER MASTER AGREEMENT                                                  PAGE 24

<PAGE>   25

         agreement with Third Party software manufacturers or suppliers, M_POWER
         passes through to Customer all warranties for Third Party software. To
         the extent MPOWER may not pass such warranties through, MPOWER hereby
         makes to Customer the same Third Party software warranties as
         manufacturers or suppliers make to MPOWER.

         AS DOCUMENTED WARRANT,. During the warranty period, MPOWER warrants
         that MPOWER Release will operate in accordance with the Documentation,
         including Third Party software documentation (the "As Documented
         Warranty"). Upon receipt of notice from Customer of a breach of the
         As-Documented Warranty, MPOWER will correct the breach, in accordance
         with the corrective-maintenance provisions of the Support and
         Maintenance Agreement.

         PHYSICAL MEDIA WARRANTY. MPOWER warrants that MPOWER Release is and
         will be free from physical defects in each media that contains MPOWER
         Release (the "Physical media Warranty"); provided, however, (i) the
         Physical Media Warranty does not apply to defects discovered more than
         90 days after the date of installation of MPOWER Release by MPOWER; and
         (ii) Customer's sole remedy for breach of the Physical Media Warranty,
         to the exclusion of all other remedies, shall be replacement by MPOWER
         of any copy of MPOWER Release that does not comply with this warranty.

         B. YEAR 2000 WARRANTY.

         The MPOWER Release software shall be Millennium Compliant. As used in
         this Agreement, "Millennium Compliant" shall mean the ability of MPOWER
         Release software to perform the following functions: a) consistently
         handle date information before, during, and after January 1, 2000,
         including but not limited to accepting date input, providing data
         output, and accurately performing calculations in dates or portions of
         dates, and b) function accurately in accordance with Customer's
         requirements, without interruption before and after January 1, 2000,
         without any change in operations associated with the advent of the new
         century. In the event that Customer becomes aware that MPOWER(R) will
         not or does not process data containing any dates before, during, or
         after January 1, 2000, correctly, Customer shall immediately notify
         MPOWER of that fact and MPOWER agrees to correct or replace MPOWER(R)
         to eliminate such processing problem in accordance with MPOWER's
         standard policies, which are available upon request.

         Further, MPOWER agrees to provide on-site Year 2000 compliance testing
         during the implementation phase and pursuant to Customer's
         specifications and requirements.

         The foregoing is Customer's sole and exclusive remedy for breach of
         warranty. The warranty set forth above is made to and for Customer's
         benefit only. The warranty will apply only if no modification,
         alteration or addition has been made to MPOWER(R) by persons other than
         MPOWER or MPOWER's authorized representative.

         In no event will MPOWER be liable for any loss of profits, loss of use,
         business interruption, loss of data, cover of cover, or indirect,
         special, incidental, or consequential damages of any kind in connection
         with or arising out of the furnishing, performance or use of MPOWER(R),
         whether alleged as a breach of contract or tortious conduct, including
         negligence, even if MPOWER has been advised of the possibility of such
         damages. MPOWER's liability under this limited warranty for damages
         will not, in any event, exceed the fees paid by Customer to MPOWER for
         MPOWER(R).

         C.  SERVICE WARRANTIES.

         MPOWER represents and warrants that it will perform the services
         required under this Agreement in a professional manner with the utmost
         due diligence and good faith. In addition, MPOWER represents and
         warrants that it will initiate work on urgent issues within 1 hour of
         Customer's call for assistance, at any time. Generally, "urgent issues"
         involve substantial program failure or issues whose resolution is
         critical to Customer's data processing, clinical or business
         operations.


         Disclaimer of all Other Warranties and Representations. THE EXPRESS
         WARRANTIES AND REPRESENTATIONS SET FORTH IN THIS AGREEMENT ARE IN LIEU
         OF, AND CUSTOMER ACKNOWLEDGES THAT MPOWER DISCLAIMS, ANY AND ALL OTHER
         WARRANTIES, CONDITIONS, OR REPRESENTATIONS (EXPRESS OF IMPLIED, ORAL
         OR WRITTEN), WITH RESPECT TO THE SYSTEM OR ANY COMPONENT THEREOF,
         INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
         PURPOSE.

         D.  NON-INFRINGEMENT INDEMNITY.

         Covenant to Defend and Indemnify. As a covenant separate from the
         representation and warranty of non-infringement contained in Section
         entitled Non-Infringement Warranty, MPOWER will defend, hold harmless
         and indemnify Customer from any and all Claims brought against Customer
         by any third party arising from or related to Customer's use of MPOWER
         Release or MPOWER's Services subject to Section VIII, Customer
         Responsibilities provision as established herein and to Limitations of
         Liability as established in Section IX of the Master Agreement.

<PAGE>   27

         CONDITIONS FOR MPOWER'S DEFENSE. If a third party asserts an
         infringement claim: (i) Customer shall promptly advise MPOWER of the
         existence of the claim within 30 days of receipt of a written statement
         of the claim against Customer (whether or not litigation or any such
         action has occurred); (ii) MPOWER shall have the sole right to control
         the defense and/or settlement of all such claims, in litigation or
         otherwise; provided, however, that (A) any settlement does not
         adversely affect Customer's ability to exercise the License Rights or
         obligates Customer in any way to the third party without Customer's
         prior written consent; and (B) MPOWER can demonstrate, upon Customer's
         request, MPOWER's financial ability to defend and indemnify Customer.
         Customer shall have the right, at Customers expense, to engage separate
         legal counsel to monitor and advise Customer regarding such defense.
         Any delay in notifying MPOWER of a claim as set forth in this Section
         shall not relieve MPOWER of its indemnity obligations hereunder, unless
         such delay materially prejudices MPOWER.

         MPOWER'S RIGHT TO CURE. If MPOWER Release is found to infringe any
         third party intellectual property right, at MPOWER's sole discretion
         and expense, MPOWER may:

         (1) obtain a license from such third party for Customer's benefit; or
         (2) replace or modify the MPOWER so that it is no longer infringing.

         INFRINGEMENT INJUNCTIONS OBTAINED BY THIRD PARTIES. If a third party
         infringement claim is sustained in a final judgment from which no
         further appeal is taken or possible, and which enjoins Customer from
         continued use of MPOWER Release or portions thereof, then MPOWER shall,
         at its sole expense: (i) procure for Customer (at MPOWER's expense) the
         right to continue to use MPOWER Release pursuant to this Agreement,
         including all License Rights; or (ii) replace or modify M_POWER Release
         to make it non-infringing.

         CUSTOMER'S OPTION TO TERMINATE. If Customer is ordered by a court to
         cease use of MPOWER Release or of specific functions(s) of MPOWER
         Release, or if MPOWER's replacement or modification of MPOWER Release
         is not acceptable to Customer, then Customer will have the option to
         terminate this Agreement pursuant without opportunity to cure.


V.       SOFTWARE MAINTENANCE SERVICES

         In consideration of payment of the annual Maintenance Fee(s) set forth
         in Section VIII B of this Attachment, Customer agrees to purchase, and
         MPOWER agrees to provide Customer on an annually renewable basis with
         software maintenance services for MPOWER(R) as follows (provided
         Customer allows MPOWER, at MPOWER's request, dial-up access to
         MPOWER(R)):







MPOWER MASTER AGREEMENT                                                  PAGE 27

<PAGE>   28

         A.       any and all Releases regarding MPOWER(R) issued by MPOWER;

         B.       any and all updates to the Documentation issued by MPOWER; and

         C.       remote diagnostic support (including dial-up capabilities)
                  regarding MPOWER(R)to include error analysis and, where
                  possible, correction services, twenty-four (24) hours per day,
                  seven (7) days per week. Any on-site assistance which Customer
                  may request and which is provided by MPOWER, which, in
                  MPOWER's reasonable opinion, is not necessary to determine the
                  nature and resolution of any problems Customer may have with
                  MPOWER(R)shall be provided by MPOWER at its then-current
                  rates. If Customer notifies MPOWER that it suspects a material
                  error in the program logic of MPOWER(R)or in the
                  Documentation, MPOWER shall make all reasonable efforts to
                  confirm the existence of the error and correct it. If the
                  parties mutually determine that no such error exists, Customer
                  agrees to pay MPOWER for its services at MPOWER's hourly rates
                  then in effect and to reimburse MPOWER for any and all
                  reasonable travel and living expenses incurred by MPOWER in
                  rendering such services. MPOWER will use its Severity
                  Designations in effect from time to time to provide remote
                  diagnostic support. The current Severity Designations and
                  attendant response times are given in Exhibit G to this
                  Attachment.

         Notwithstanding the foregoing, should Customer be utilizing any Release
         of MPOWER(R) other than the then-most-recent Release, or the Release
         prior to the then-most-current Release, provided such Release has been
         available for Customer's use for a period of twelve (12) months or
         longer, MPOWER reserves the right, at its sole option, to terminate its
         obligations to provide maintenance services under this Section V at any
         time upon giving thirty (30) days' prior written notice to Customer. If
         such a condition exists, MPOWER and Customer agree to negotiate in good
         faith to define reasonable terms, conditions and fees for MPOWER to
         provide Customer with maintenance services for such then non-current
         Release.

         MPOWER's providing Customer with maintenance services as described in
         this Section V shall automatically continue, on an annual basis, unless
         either party shall give written notice to the other that it desires not
         to renew such maintenance services. The parties agree that such written
         notice shall be remitted for receipt by the other no less than ninety
         (90) days prior to the end of the then-current annual maintenance
         period.

VI.      IMPLEMENTATION AND CONVERSION SERVICES

         by Customer.

         MPOWER reserves the fight to subcontract any Implementation Services
         responsibilities it may accept under this Agreement. Customer shall
         have the fight to approve MPOWER's subcontractors, which approval shall
         not be unreasonably withheld. If Customer objects to certain
         subcontractors for a stated good cause, MPOWER and Customer agree to
         seek a mutually agreeable resolution to Customer's objection.


VII.     TRAINING SERVICES

         MPOWER will provide up to eighty (80) hours of initial trainer services
         training within the scope of payment of initial Implementation Fees, as

         subsystems of MPOWER(R) and will be inclusive of the following:

         o        Mapping of business rules to benefit plan templates;

         MPOWER's then-current fees, with additional training sessions regarding
         MPOWER(R) to a reasonable number of Customer's personnel. All such
         training, including initial End User training, shall be conducted at
         location(s) elected by Customer at time(s) which are mutually
         acceptable to both parties. Current fees for additional training
         sessions are provided in Section VIII.F.

                  Customer agrees to pay MPOWER a license fee ("Initial License

                           Severity Definitions and Resolution Process

o        SEVERITY 1.
         The problem causes complete loss of service in the production and
         staging environment and work cannot reasonably continue. The problem or
         defect has one or more of the following characteristics:

         [ ]   Data corruption. Physical or logical data is unavailable or
               incorrect. Examples: Block format corruption, invalid indices,
               corruption of meta-data, incorrect results.

         [ ]   Critical functionality is not available.

         [ ]   System hangs. The process hangs indefinitely or there is severe
               performance degradation, causing unreasonable waits for resources
               or response, as if the system is hanging.

         [ ]   The entire MPOWER application crashes repeatedly.

         [ ]   Database process or background processes fall and continue to
               fail after restart attempts.

         [ ]   Potential for above occurrences is defined imminent.


         RESOLUTION OF SEVERITY 1: Until the issue is resolved MPOWER Solutions
         will work on Severity 1 around the clock (7x24). As a result of the
         severity, the customer must provide MPOWER with a point of contact
         during the 7x24 period. The customer's point of contact will assist the
         MPOWER customer support and development staff in gathering data,
         testing fixes in the customer's testing region, and applying fixes to
         the customer production environment.

o        SEVERITY 2:
         Problem or product defect causes a severe impact on the customer's
         business regardless of customer environment. No workaround is
         available, however operations can continue in a restricted fashion. The
         problem or defect has one or more of the following characteristics:

         [ ]   Business Impact Examples: The customer can handle current volume,
               but will not be able to handle quarter close; At close, customer
               finds totals wrong, but close is not for a few weeks.

         [ ]   Internal software error, causing the application to fall to run
               to completion, or return wrong results, or software error
               severely degrades performance.

         [ ]   Some important functionality is unavailable, yet the system can
               continue to operate in a restricted fashion.

         [ ]   Potential for above occurrences is defined imminent.

<PAGE>   41

         RESOLUTION OF SEVERITY 2: MPOWER Solutions will work on Severity 2 bug
         based on customer assigned priority. Severity 2 fixes will be added in
         the next scheduled maintenance or patch release.

o        SEVERITY 3.
         Problem or product defect causes minimal impact on the Customer's
         business. The impact of the problem or defect is minor or an
         inconvenience, such as a manual bypass to restore product
         functionality. The problem or defect has one or more of the following
         characteristics:

         [ ]   A software error for which there is an acceptable workaround.

         [ ]   Software error minimally degrades performance.

         [ ]   Software error or incorrect behavior has minor impact the
               operation of the system.

         RESOLUTION OF SEVERITY 3: Fixes for severity 3 bugs will be added to
         the priority list for the next major scheduled release of the product.
         The order of priority for resolving severity 3 issues will be assigned
         jointly by the Customer and MPOWER.

o        SEVERITY 4.
         The problem or product defect causes NO impact on the Customer's
         business. The problem or defect is a minor error, incorrect behavior,

                           AMENDMENT NO. 1 TO
                           MASTER AGREEMENT


         This Amendment No. 1 (the "Amendment") to the parties' February 4, 1999
Master Agreement is 'entered into as of the date of the later signature below by
and between Xcare.net, a Delaware corporation with its principal office at 6400
S. Fiddler's Green Circle, Suite 540, Englewood, Colorado 80111 ("Xcare.net")
and Methodist Care, Inc., a Texas licensed health maintenance organization, with
its principal office at Two Greenway Plaza, Suite 500, Houston, Texas 77046
("Customer").

         WHEREAS, on February 4, 1999 Xcare.net (formerly "Mpower Solutions
Inc.") and Customer entered into a Master Agreement (the "Master Agreement");
and

         WHEREAS, the parties desire to amend the Master Agreement as set forth
herein.

         NOW, THEREFORE, for good and valuable consideration the receipt of
which is hereby acknowledged, the parties agree that the Master Agreement is
amended to include the following:

         1. For the duration of the Master Agreement and for a period of one
year after the service are completed, Client agrees not to employ or solicit the
employment of any Xcare.net personnel who performed services under the Master
Agreement. Customer agrees to pay Xcare.net an amount equal to the annual
compensation of such personnel for the one-year period immediately preceding any
hiring or solicitation of any such Xcare.net personnel. This payment by Customer
constitutes the parties' estimates of that portion of Xcare.net's damages for
which Customer should be responsible for such activity, and is not a penalty.
The parties agree that this estimate is reasonable under the circumstances
existing as of the date of this Agreement, including, without limitation, the
difficulty of computing such damages exactly.

         2. Except as expressly provided in this Amendment, the Master Agreement
shall remain unmodified and in full force and effect. In the event of any
inconsistency or conflict, the provisions of this Amendment shall control and
govern over the provisions of the Master Agreement.

                              ARTICLE 20. DISPUTES

A.      Good-Faith Negotiations. If any dispute arises under this agreement that
        is not settled promptly in the ordinary course of business, the parties
        shall seek to resolve any such dispute between them, first, by
        negotiating promptly with each other in good faith in face-to-face
        negotiations. If the parties are unable to resolve the dispute within 20
        business days (or such period as the parties shall otherwise agree)
        through these face-to-face negotiations, then any such dispute shall be
        resolved in the following manner.

B.      Excluded Causes. If the only dispute relates to unpaid fees, costs or
        other charges, the party owed the money may commence legal action in
        court for outstanding monies due under this Agreement.

C.      Binding Alternative Dispute Resolution. Any remaining dispute arising
        under this Agreement shall be resolved by using alternative dispute
        resolution (ADR) procedures, which can hopefully avoid or reduce the
        acrimony resulting from adversarial litigation. If the efforts through
        face-to-face negotiations in paragraph A., above, are not successful,
        the parties will initiate a mini-trial (ADR) process with selection of a
        neutral advisor, who will schedule a mini-trial to occur approximately
        30 business days after the selection of the neutral advisor. The neutral
        advisor will introduce an impartial opinion approximately 15 business
        days after completion of the mini-trial. Throughout the ADR process, the
        neutral advisor will provide an element of mediation with the goal of
        having the parties resolve the dispute without issuance of the impartial
        opinion. However, if agreement is not reached by the parties, the
        impartial opinion rendered by the neutral advisor will be binding and
        judgment upon that opinion may be entered in any court having
        jurisdiction thereof. The parties may elect to use an
        arbitration/mediation service which specializes in timely ADR,

        such as ENDISPUTE or the Judicial Arbitration and Mediation Services,
        Inc. All expenses such as the cost of the neutral advisor or the hearing
        facility will be shared equally.

                            ARTICLE 21. TERMINATIONS

A.      In addition to the termination provisions of FAR 52.249-2 and 52.249-6

        such part thereof as may be engaged in the performance of this

                               SPECIAL PROVISIONS

The special provisions of the Prime Contract are hereby incorporated by
reference in the following pages. As used herein the term "Contractor" shall
mean the Subcontractor and the terms "Government" and the "Contracting Officer"
or equivalent terms shall mean PRC and PRC Contractual Representative hereunder,
respectively, except under those clauses relating to rights to audit or examine
the Subcontractor's books or financial records, in which case the terms the
"Government" and the "Contracting Officer" shall mean the U.S. Government and

ARTICLE 20. COMMERCIAL OFF THE SHELF (COTS) PRODUCTS AND DATA STANDARDIZATION

A.      Background

        1.      The Government intends to use international, industry,
                government, DoD, and Military Health Systems (MHS) standards to
                promote the efficient and unambiguous exchange of information
                with required government and commercial systems. In addition,
                the government must understand the meaning and context of the
                data being captured and processed to ensure a common
                understanding of the data being exchanged.

        2.      Congress defined performance measures to assess progress toward
                information technology goals in the National Defense
                Authorization Action for Fiscal Year 1995 to ensure that the DoD
                receives the maximum benefit possible from development,
                modernization, operation, and maintenance of automated
                information systems (AISs). Section 381 paragraph 1.3.2 of this
                Act specifically establishes measures for data standardization
                to include the number and percentage of DoD standard data
                elements that are used in migration programs. The paragraph
                further states that this can be done through actual use of DoD
                standard data elements of the mapping of non-standard data to
                DoD standard data.

        3.      Therefore, it is the purchasing organizations responsibility to
                ensure the COTS software vendor provides the following minimum
                information in the form of data dictionary to DoD Health
                Affairs: the logical data element name, its definition that
                describes the meaning and the context of the data element in the
                system, the domain of the data element (the allowable values),
                the data type, length and unit of measure if applicable. Any
                data element acronym or abbreviation must be spelled out clearly
                in the definition. The vendor is required to submit this data
                dictionary using the MHS Health Import Tool (HITool) which can
                be obtained from MHS Health Data Program Web Site. This tool
                ensures that Health Affairs has the necessary data element
                information in a useable format. In addition, the vendor will be
                required to assist Health Affairs in reporting the metric
                described above. These requirements are described in paragraph
                below entitled "COTS Software Data Requirements.

B.      Scope. These contract requirements apply to COTS software purchased to
        satisfy Military Health System (MHS) functional requirements. They do
        not apply to development tools such as PowerBuilder, Visual Basic,
        utilities, etc., office automation software such as word processors of
        infrastructure-related software such as operating systems. The
        Government will include these requirements in each task statement or
        acquisition document which includes or anticipates the need for COTS
        software. to satisfy functional requirements.

C.      COTS Software Data Requirements. Prior to final agreement and purchase,
        the COTS software vendor shall provide a data dictionary which includes
        the following information for each functional data element in the
        software: the logical data element name; its definition that describes
        the meaning and the context of the data element in the system; the
        domain of the data element (the allowable values); the data type, length
        and a unit of measure if applicable. The vendor is required to submit
        this data dictionary using MHS Health Import Tool (HITool) which can be
        obtained from http://hirs.brooks.aff.mill/mhss/. In addition, the vendor
        will be required to provide additional information for clarification of
        the individual data element meaning and context to assist Health Affairs
        in reporting the National Defense Authorizations Action data
        standardization metric as required in Section 381 of the National
        Defense Authorization Action for Fiscal Year 1995.

D.      COTS Software Data Import and Export Capability. The COTS software
        vendor shall describe in its proposal to the Government and be able to
        demonstrate the applications capability and flexibility to import and
        export applicable standard MHS data defined in the task order to or from
        external sources directly or through standardized interfaces, front-end
        or back-end translators or utilities.

                DoD Property in the Custody of Contractors, or approved
                substitute, including instructions on the reverse side of the
                form;

        (3)     In duplicate, to the cognizant Government property
                administrator, no later than October 31.

(b) The Contractor is responsible for reporting all Government property
accountable to this contract, including that at subcontractor and alternate
locations.

H.2     CONFLICT OF INTEREST

It is understood that the Contractor, to include all subcontractors and
consultants, shall comply with the provisions of FAR Subpart 9.5 -
Organizational Conflicts of Interest. If the Contractor is issued a delivery
order to provide services, any of the services set forth in FAR 9.505-1, 9.505-2
and 9.505-3, the Contractor or any subcontractors or consultants working on that
delivery order shall not supply any hardware, software or other services
resulting from that order for a period of three (3) years from the completion of
that delivery order. Each delivery order subject to the Organizational Conflict
of Interest provisions above will specify the limitations required by FAR
Subpart 9.5.

        1. Constraints on Awards. An Offeror may propose as prime or
        subcontractor on multiple D/SIDDOMS Lots. However, awards are subject to
        the following contract exclusions:

                a. Lot I awardee(s) is eligible for award(s) for Lot II and LOT
                IV or the awardee(s) of Lot I is eligible for award of Lot III
                but not the combination of Lot II, Lot III, and Lot IV. The
                awardee(s) of Lot II is eligible for award(s) of Lot I and Lot
                IV. The awardee(s) of Lot III is eligible for award of Lot I.
                but not Lot II and Lot IV. The awardee(s) of Lot IV is also
                eligible for Lot I and Lot II but not Lot III.

                b. The (OASD/HA) DMIM Program Office must maintain independence

                design, development, deployment. operations and maintenance
                tasking of Lot III. The purpose of the restriction is to prevent
                a bias in the contractor's judgment in suggesting
                recommendations or solutions to be implemented under Lot III.
                Furthermore, it would provide Lot III awards an unfair
                consideration in the issuance of delivery orders.

                c. The Contractor shall obtain a written response and approval
                from the Contracting Officer when there is any doubt,
                whatsoever, as to whether or not the furnishing of services,
                equipment or software to the Government as a result of any
                tasking performed under this contract represents a conflict of
                interest.

NOTE: For the purposes of this clause, the "Contractor", or "Subcontractor", or
"Consultant" means the Contractor, its subsidiaries and affiliates, joint
ventures involving the Contractor, any entity with which the Contractor may
hereafter merge or affiliate with, and other successor in interest or assignee
of the Contractor. Additionally, the reference to (OASD/HA), DMIM shall be
understood to mean any name for this Government organization which shall be
changed during the period specified by this clause as a result of a
re-organization, etc., for which a new name cannot be anticipated at this time.

                        (JUL 1995)

        (a) Except as provided in (b) below, the Contractor shall not enter into
        any agreement with an actual or prospective subcontractor, nor otherwise
        act in any manner, which has or may have the effect of restricting sales
        by such subcontractors directly to the Government of any item or process
        (including computer software) made or furnished by the subcontractor
        under this contract or under any follow-on production contract.

        (b) The prohibition in (a) above does not preclude the Contractor from
        asserting rights that are otherwise authorized by law or regulation.

        (c) The Contractor agrees to incorporate the substance of this clause,
        including this paragraph (c), in all subcontracts under this contract
        which exceeds $100,000.

                        DEBARMENT (JUL 1995)

        (a) The Government suspends or debars Contractors to protect the
        Government's interest. The Contractor shall not enter into any
        subcontract in excess of $25,000 with a Contractor that is debarred,
        suspended, or proposed for debarment unless there is a compelling reason
        to do so.

        (b) The Contractor shall require each proposed first-tier subcontractor
        whose subcontract will exceed $25,000, to disclose to the Contractor, in
        writing, whether as of the time of award of the subcontract the
        subcontractor, or its principals, is or is not debarred, suspended, or
        proposed for debarment by the Federal Government.

        (c) A corporate officer or a designee of the Contractor shall notify the
        Contracting Officer, in writing, before entering into a subcontract with
        a party that is debarred, suspended, or proposed for debarment (see FAR
        9.404 for information on the List of Parties Excluded from Federal
        Procurement and Nonprocurement Programs). The notice must include the
        following:.

                (1) The name of the subcontractor.

                (2) The Contractor's knowledge of the reasons for the
                subcontractor being on the List of Parties Excluded from Federal
                Procurement and Nonprocurement Programs.

                (3) The compelling reason(s) for doing business with the
                subcontractor notwithstanding its inclusion on the List of
                Parties Excluded from Federal Procurement and Nonprocurement
                Programs.

                (4) The systems and procedures the Contractor has established to
                ensure that it is fully protecting the Government's interests
                when dealing with such subcontractor in view of the specific
                basis for the party's debarment, suspension or proposed
                debarment.

I.108   52.222-42       STATEMENT OF EQUIVALENT RATES FOR FEDERAL HIRES (MAY
                        1989)

In compliance with the Service Contract Act of 1965, as amended, and the
regulations of the Secretary of Labor (29 CFR Part 4), this clause identifies
the classes of service employees expected to be employed under the contract and
states the wages and fringe benefits payable to each if they were employed by
the contracting agency subject to the provisions of 5 U.S.C. 5341 or 5332.

THIS STATEMENT IS FOR INFORMATION ONLY: IT IS NOT A WAGE DETERMINATION

I.109   52.232.18       AVAILABILITY OF FUNDS (APR 1984)

Funds are not presently available for this contract. The Government's obligation
under this contract is contingent upon the availability of appropriated funds
from which payment for contract purposes can be made. No legal liability on the

J.1     STATEMENT OF WORK FOR D/SIDDOMS II LOT III, DESIGN, DEVELOPMENT,
        DEPLOYMENT, OPERATIONS AND MAINTENANCE

1       Overview

1.1     Introduction

The Office of the Assistant Secretary of Defense (Health Affairs) (OASD(HA)) has
a requirement to provide support for ongoing and future health care programs.
This requirement is known as the Defense Medical Information Management/Systems
Integration, Design, Development, Operations and Maintenance Services
(D/SIDDOMS) II. D/SIDDOMS II is an expanded requirement to the current D/SIDDOMS
contract. The resultant contracts will be Indefinite Delivery/Indefinite
Quantity (IDIQ) type contracts for use by all components of the Military Health
Services System (MHSS) to support their medical information management systems
needs. It may also be made available to other agencies to use appropriate
support capabilities required by the Department of Defense to accomplish its
Health Affairs mission.

1.2     Contract Type

The resultant contracts will be IDIQ style contracts. The Government anticipates
the use of multiple contract types on a Delivery Order (DO) basis.

1.3     Award

The D/SIDDOMS II program consists of four (4) Lots. Each Lot is being
implemented as a separate procurement. The intent is to award multiple contracts
for all Lots, based on the quality of the proposals and availability of funds.
It is also the intent that Lot IV be set aside for small businesses. Each Lot is
designed to meet specific needs in the overall system life cycle. Procurement

1.5     Scope

D/SIDDOMS II will cover a wide spectrum of specific functional and information
technology functions for all Information Management/Information Technology
(IM/IT) and related requirements within the MHSS. D/SIDDOMS II will utilize
highly skilled personnel and processes in performance of all IM/IT and related
functions. At a minimum, services will consist of the following: studies,
functional requirements definition, systems engineering, database design, data
administration, software customization, communications, networking, user
support/problem resolution, product support, training, IT reengineering support,
technology evaluation, technology insertion/refreshment, operations,
installation/reinstallation, maintenance/repair, configuration and inventory
management. The Government anticipates tonal system solutions, as directed by
individual DO, to include all necessary hardware, software, local communications
and related expenses to meet the functional and technical requirements.

1.6     Background

1.6.1   The TRICARE Program

DoD operates one of the nation's largest health cam systems. With more than 8
million people eligible to receive case through the MHSS, it has a vital mission
in both wartime and peacetime. The wartime mission is to provide medical support
to active-duty military members in preparation for and during wartime or other
contingencies. The peacetime mission is to maintain the health of the 1.7
million people on active duty and m provide medical care to more than 6 million
non-active-duty beneficiaries at Military Treatment Facilities (MTFs) or at
civilian facilities under the TRICARE program.

TRICARE is the DoD regional, managed care program for active-duty and retired
members of the uniformed services, their families, and their survivors.
Congress, in the National Defense Authorization Act of 1994, directed DoD to
proscribe and implement a health benefit option for beneficiaries eligible for
health case under Chapter 55 of Title 10, United States Code. The program was
modeled on health maintenance organization (HMO) plans offered in the private
sector and other similar Government health insurance programs. In addition
beneficiaries who enroll in the health benefit option would have reduced
out-of-pocket costs and a uniform benefit structure. Congress further directed
that the costs to DoD would be no greater than those normally incurred to
provide health care to the covered beneficiaries who enroll in the option.

To conform with the directives in the 1994 Authorization Act, DoD developed a
regional managed health care strategy, in cooperation with the Services, that
restructures the MHSS into 12 CONUS health services regions. Two additional
overseas regions that encompass Europe and the Pacific region have been
established. Each region is administered by a Lead Agent. Responsibilities of
the Lead Agent include collaborating with the other MTF commanders within the
region to develop an integrated plan for delivering health case for their
beneficiaries. Regional TRICARE plans are being put in place, and procurement
schedules have been developed to support these initiatives. The TRICARE program
is expected to be implemented fully throughout the United States in calendar
year 1997 (CY97).

In the TRICARE environment, the MHSS must maximize health care dollars by
continuing to examine all options for meeting the legal requirements to provide
quality and timely preventive health care to DoD beneficiaries. TRICARE, through
employment of a flexible delivery structure, must complement the readiness
mission to ensure that the medical sustaining base can fully support deployed
forces and absorb additional patient workload without sacrificing access and
high-quality care delivery to all nondeployed beneficiaries.

While TRICARE is a medical force multiplier, it will also demand greater
attention from IM/IT for data standardization and interoperability to ensure
that the distributed computer-based patient records (CPRs) are easily accessed
and totally compatible around the world. Special contractual and security
arrangements will be necessary to ensure that TRICARE support contractor systems
can support the distributed CPR capability with standardized data, allow
authorized users to have ready access to MHSS hosted portions of individual
CPRs, and support fast response to MHSS originated CPR and case assessment
queries.

1.6.2   The MHSS

The MHSS uses information management/information technology capabilities to
assist the MTFs in the delivery of quality patient care to the population served
within the MHSS. Over 100 automated information systems (AISs) in the MHSS are
in the process of being migrated to a small number of business area (functional
area) based target migration systems. The MTFs have a wide range of physical
configuration ranging from small offices with a few workstations and dial-in
communications to clinics with local area networks (LANs) with moderate external
connectivity to large hospitals with extensive internal LANs and external
connectivity. Data handling needs also vary tremendously from moderate text and
office automation needs through video conferencing to large medical imagery
files.

The environment of the MHSS is significantly different than civilian health care
delivery systems. Several points are presented to illustrate the differences.

        a. The MHSS mission is to maintain the health status of the members of
        the armed force, their families and others entitled to DoD health care
        by providing total inpatient and outpatient care and to maintain medical
        readiness to support mobilization.

        b. A significant feature of the MHSS is the volume of outpatient care
        provided at MTFs. Unlike the civilian health care delivery systems,
        where private physicians provide the bulk: of outpatient care in their
        office, DoD provides this ambulatory care to the entitled population in
        hospital clinics and remote support clinics using primarily hospital
        staff.

        e. The MHSS includes over 100 hospitals and major clinics and more than
        500 separately located other medical facilities throughout the world in
        addition to the TRICARE providers/facilities.

The Assistant Secretary of Defense (Health Affairs) (ASD(HA)) oversees all
aspects of the MHSS Program. In addition, the ASD(HA) works with the individual
Military Departments and obtains support from non-DoD Government agencies and
civilian Contractor(s).

In view of both the number and diversity of organizations processing military
hospital information. as well as the fact that major information processing
requirements among these organizations are similar, the general automation
approach is to centralize and coordinate the application development using
appropriate open systems technology and standards and the MHSS Infrastructure.
The MHSS Infrastructure was developed to provide a common set of standardized
interfaces across platforms and configurations to facilitate communications,
data and resource sharing among defense medical systems. Standardized systems
are being developed by defining common requirements and implementing
standardized system capabilities while supporting Service-unique needs.

In October 1989, the Deputy Secretary of Defense established the Corporate
Information Management (CIM) initiative. This initiative is primary objectives
and goals were to promote data standardization, quality and consistency, to
eliminate duplication of effort in the development and maintenance of software,
and to improve effectiveness in the Information Resource Management (IRM) life
cycle. The process led to the identification and selection of Fifty-two
medical/health migration systems and a goal of the eventual elimination of all
associated legacy systems. The final vision of the MHSS is based on information
management/information technology strategic planning centered around the
evolution to a business area focus, emphasizing critical functional areas using
functional, technical and data standardization.

1.6.3   The Functional Architecture

The functional architecture, as shown in Figure 1, Health Functional
Architecture, groups the Health functions into four major business areas:
Clinical, Logistics, Resources. and Executive Information/Decision Support. Each
of these four business areas will be supported by an information system
capability that will be a compendium of standards-based and integrated
commercial off-the-shelf (COTS), Government-off-the-shelf (GOTS), or, if no
alternative exists. MHSS-developed functional applications. These system
capabilities include the Composite Health Care System II (CHCS II), Defense
Medical Logistics Standard Support II (DMLSS II), Health Standard Resources
System (HSRS), and Corporate Executive Information System (CEIS).

The MHSS also interfaces with other DoD mission support areas, such as
Personnel. Finance. Logistics, and Transportation. These nonmedical functions
are important to effectively and efficiently meet the full mission of the MHSS
and are represented by the nonmedical area notation in Figure 1.

Business and mission needs drive the IM/IT requirements from Business Process
Reengineering (BPR) to MHSS Program Objective Memorandum (POM) development,
budget execution, and IM/IT strategic planning. IT investment provides a force
multiplier to ensure that the information needs of the MHSS are met by providing
the right information to the right location at the right time.



                    Figure 1 - Health Functional Architecture


                        [OPERATIONAL CONTINUUM GRAPHIC]




                                     J.1 - 4

<PAGE>   57

Functional requirements are derived from business needs, thereby building the
basis for MHSS IM/IT support requirements. BPR and functional process
improvement outputs are used to build the requirements that drive IM/IT. Mapping
of functional requirements is an important Step to ensuring that the
requirements are addressed only once and that like requirements from different
functional processes are aggregated and addressed in one technical area.

1.6.4 MHSS Information Management Strategic Principles

The MHSS Information Management/Information Technology Program is based on the
following principles:

        Information management entails planning, programming, benefits
        estimation, funding, deployment, implementation, and benefits
        realization and is the responsibility of all managers throughout the
        MHSS consistent with centrally developed policy.

        Information management will support comparable performance measurements
        across the Military Services and the private sector.

        Information will be managed so it improves the understanding of how to
        effectively and efficiently provide health services so that informed
        choices can be made by providers and beneficiaries based on the
        recognition of best value.

        Information architecture will be maintained so that computing and
        communications infrastructure components are interchangeable,
        interoperable, and transparent to the user.

        Information will be available when and where needed and protected from
        unintentional or unauthorized alteration, destruction. or disclosure.

        Operational efficiency will be accomplished. whenever possible, using
        process reengineering to simplify and integrate common functions before
        investing in new or additional information technology.

        Common functions will be supported by single, integrated information
        management approaches, consisting of uniform data sets. processes, and
        technical standards.

        New business and information management processes will be validated
        through maximum use of prototyping before system-wide deployment.

        Whenever practical. competitive bidding will be used to obtain
        off-the-shelf products for information management from the most
        cost-effective sources, rather than new development.

        Processes will be engineered so that data is entered only once, at the
        point of origin.

        Information management capabilities will offer consistent presentation,
        will be easy to use, and will be acceptable to users.

        Information management capabilities will be deployed incrementally to
        accelerate uniform benefit realization for all MHSS beneficiaries.

1.6.5   Emerald City

Health Affairs has developed a vision called Emerald City, with a complete set
of strategic and Automated Information System (AIS) plans in support of the
goals of military medicine and the Military Health Services System (MHSS) in the
year 2000 and beyond.

The Emerald City vision encompasses several key points:



                                     J.1 - 5

<PAGE>   58

1)      FOCUS IS ON MEDICAL READINESS

Medical readiness encompasses the ability to mobilize, deploy, and sustain field
medical services and support all operations requiring military services; to
maintain and project the continuum of health care resources required to provide
for the health of the force; and to operate in conjunction with beneficiary
health care.

        The goal of the MHSS is to support military medical readiness by
        positioning the MHSS to adapt rapidly to change, to be responsive, and
        to be flexible in its capability to support all users in all operational
        settings-worldwide. The core IM/IT areas that are critical in providing
        the flexible, responsive services necessary to meet MHSS needs include-

        Business process reengineering (BPR)

        Cross business area functional requirements integration

        MHSS infrastructure standardization

        Data standardization and implementation

        Automated information system (AIS) migration

        DoD-wide systems integration and open systems standards conformance that
                incorporates accessibility for individuals with disabilities

        A common operating environment (COE)

        Performance measurements tailored to the Health business area

        Information security

2)      COMPATIBLE WITH GCCS AND GCSS

The MHSS technical architecture is based on the Technical Architecture Framework
for Information Management (TAFIM) client/server model and open systems
specifications that support cost-effective interoperability and scalability, the
identification of the components and services that implement the IM/IT goals,
and the development of a framework within which the systems interoperate. The
technical architecture consists of three tiers: presentation, application, and
data. The enabling framework for the technical architecture is the Health
Information Infrastructure (HII). The HII is based on the open systems
specifications contained in the Technical Architecture Framework for Information
Management (TAFIM), the Joint Technical Architecture (JTA), the Defense
Information Infrastructure (DII) Strategic Enterprise Architecture, and the
DII/COE Integration and Runtime Specification. Implementation of the HII will
ensure that the MHSS is totally integrated and fully compatible with the DII,
DII/COE, Global Command and Control System (GCCS), Global Combat Support System
(GCSS), and Defense Information Systems Network (DISN).

3)      COMPATIBLE WITH DII/COE

The MHSS COE is being developed from baseline standards and requirements such as
the TAFIM, JTA, and DII COE. The DII COE primarily supports the Global Command
and Control System (GCCS) requirements with an emphasis on X-Windows client and
UNIX Server architecture. The MHSS COE will standardize on the Windows NT
client/server model (95% solution) with Unix as an acceptable alternative. It
will provide the MHSS "medical-variant" architectural principles, guidelines,
and methodologies for the development of MHSS applications software by
capitalizing on a thorough and cohesive set of infrastructure support services.

4)      SUPPORTS FULL OPERATIONAL CONTINUUM

The MHSS must support the full operational continuum from the sustaining base to
the deployed unit. Scalability, flexibility, and reliability are critical
requirements for the deployed MHSS AISs to ensure that the MHSS is fully
functional and provides support for the full range of user needs in
theater/contingency and operations other than war.

Capabilities must be built into the systems and stress tested regularly during
training exercises using the deployable asset configurations to ensure that the
systems function properly and that they can be used effectively. User interface
with the systems must be standardized to ensure that system use in the theater
configuration is consistent with the peacetime operation so that no special
training is required under deployment conditions.



                                     J.1 - 6

<PAGE>   59

Functional requirements may vary between theater/contingency and operations
other than war. Therefore, support packages with defined capabilities must be
established for specified scenarios. Unneeded functionality must be easy to
remove to ensure that the deployed systems (hardware and software) are "lean and
mean" in weight and cube yet are capable of supporting all required
functionality for the deployed mission.

5)      REQUIRES DATA, TECHNICAL AND FUNCTIONAL STANDARDIZATION

Standardization efforts are ongoing through the development of the Health
Functional Architecture, the MHSS enterprise technical architecture, and the DoD
data standardization effort. The approach to MHSS AIS migration is based on the
following basic concepts:

        Support for the readiness mission is an essential and integral part of
        each MHSS AIS. Common sharable: resources that form the HII COE include
        the following:

                Communications

                Hardware

                Common operating system software

                Utility functions

                An integrated database environment

                Standardized data

        Systems are composed of applications, external systems interfaces, and
        subject area databases.

6)      SUPPORTS RAPID ELIMINATION OF LEGACY SYSTEMS

Health Affairs has initiated action to significantly reduce the total number of
existing MHSS migration systems. The MHSS IM/IT strategic direction is
considered to be feasible, cost effective, functionally efficient, and
consistent with the anticipated DoD direction and future MHSS needs. In this
revised structure, MHSS functionality has been grouped into four major
functional categories (business areas) capable of supporting the deployed and
peacetime/sustaining base environments. The Health Functional Architecture
groups the Health functions into four major business areas: Clinical, Logistics,
Resources, and Executive Information/Decision Support. Each of these four
business areas will be supported by an information system capability that will
be a compendium of standards-based and integrated commercial off-the-shelf
(COTS), Government-off-the-shelf (GOTS), or, if no alternative exists,

1.6.6   MHSS Acquisition Philosophy

        Acquisition is one of the enabling tools used to help support the
current MHSS and transition the MHSS to the Emerald City vision. The D/SIDDOMS
II program is one part of the dual element MHSS acquisition philosophy. The two
elements are (1) acquisition of services and support and (2) acquisition of
information technology products. The original D/SIDDOMS contracts are currently
the prime vehicle for MHSS program managers to acquire information management
and information technology related services such as application development,
studies, integration, system deployments, technical management and support, and
operations and maintenance. D/SIDDOMS II will provide enhanced and improved
support of the same nature to support the wide range of users and programs in
the MHSS. The other side of the coin is obtaining information technology
products. MHSS uses both internal and external contracting vehicles for this
purpose, The major internal contracting vehicles are the Support Hardware and
Automation Related Products (SHARP) procurements, one of which was awarded in
January 1997 and the second of which will be awarded approximately mid-1997.
SHARP provides an extensive range of hardware, software and training products
which were specified to meet the needs of a wide cross-section of MHSS users and
programs. An important aspect of the MHSS acquisition philosophy, however, is
that it is more important to adequately meet the needs of the users than it is
to force reliance upon a few contracts. Therefore, although SHARP was developed
specifically to meet MHSS needs, if those needs can be fulfilled better through
the use of other vehicles such as GSA schedules or other government agency
contracts the MHSS acquisition managers will help the users to identify the best
source and execute the purchase. One of the services that will arise from the
D/SIDDOMS II contract is expected to be assistance for users and managers in
identifying the best products and solutions, identifying appropriate sources,
and also helping to improve the acquisition vehicles for MHSS.

J.6     SECURITY REQUIREMENTS

This attachment describes types of general security requirements which apply to
work done for the MHSS. These requirements are extracted from various pertinent
security directives, instructions, etc. The Personnel Security requirements
apply to all labor categories as noted in Section J, Statement of Work. Other
requirements will apply decoding on the nature of the work being performed.

J.6.1   PERSONNEL SECURITY PROGRAM REQUIREMENTS - DoD 5200.2-R

Identify personnel (military, civilian, consultants, and contractors) who occupy
automated data processing (ADP) positions where their duties meet the criteria
for ADP-I, ADP-II, or ADP-III sensitivity designations, as described in Appendix
K. DoD 5200.2-R.

Contractor personnel performing on unclassified automated information systems
must be assigned to one of three position sensitivity designations before
commencing work on D/SIDDOMS

        1. Critical-Sensitive Positions (ADP-I positions): Those positions in
        which the incumbent is responsible for the planning, direction, and
        implementation of a computer security program; major responsibility for
        the direction, planning and design of a computer system, including the
        hardware and software; or, can access a system during the operation or
        maintenance in such a way, and with a relatively high risk for causing
        grave damage, or realize a significant personal gain. ADP-I positions
        require a Background Investigation (BI).

        2. Noncritical-Sensitive Positions (ADP-II positions): Those positions
        in which the incumbent is responsible for the direction, planning,
        design, operation, or maintenance of a computer system, and whose work
        is technically reviewed by a higher authority of the ADP-I category to
        insure integrity of the system. ADP-II positions require a National
        Agency Check plus Written Inquiries (NACI) or a DoD NACI (DNACI).

        3. Nonsensitive Positions (ADP-III positions): All other positions
        involved in computer activities, ADP-III positions require a National
        Agency Check (NAC).

J.6.2   MINIMUM GENERAL SECURITY REQUIREMENTS - DoD DIRECTIVE 5200.28

Accountability. Implement safeguards to ensure individuals with access to an
automated information system (AIS) are held accountable for their actions. A
manual or automated audit trail must be implemented that documents the
following: identity of each person and device having access; time of access;
user activities; activities that might modify, bypass, or negate safeguards
controlled by the AIS security relevant actions associated with period
processing, or the changing of security levels or categories of information.

Access. Implement an access control policy that will positively identify each
user who is authorized to access the AIS before allowing access.

SECURITY TRAINING AND AWARENESS. Establish a security training and awareness
program that will ensure all persons responsible for the AIS or information
processed and/or maintained by the AIS, or all persons who access the AIS, are
aware of proper operational and security-related procedures and risks.

PHYSICAL CONTROLS. Protect hardware, software, documentation, and data from
unauthorized disclosure, destruction or modification. Protective means can
include personnel, physical, administrative, and configuration controls. The
level of control must be commensurate with the maximum sensitivity of the
information.



                                     J.6 - 1

<PAGE>   73

MARKING. Mark AIS output media, and media containers to accurately reflect the
sensitivity of information. Mark unclassified sensitive information in
accordance with Enclosure 3, paragraph S, DoDD 5200.28, and Chapter IV, DoD
5400.7-R.

LEAST PRIVILEGE. Ensure the AIS functions in a manner that each user has access
only to information to which the user is entitled, and no more.

DATA CONTINUITY. Control accessibility, maintenance, movement, and disposition
of each file or data collection so that each has an identifiable source
throughout its life cycle and is governed by security clearance, formal access
approval, and need-to-know.

DATA INTEGRITY. Implement safeguards to detect and minimize inadvertent
modification or destruction of data, and detect and prevent malicious
destruction or modification of data.

CONTINGENCY PLANNING. Develop and test a contingency plan to ensure AIS security
controls function reliably, and are maintained continuously during periods of
interrupted service. Ensure the plan includes procedures to recover data that
has been modified or destroyed.

ACCREDITATION. Accredit each AIS and network to operate in accordance with a set
of Designated Approving Authority (DAA) approved security safeguards.

RISK MANAGEMENT. Implement a risk management program to determine how much
protection is required by the AIS, the level provided, how much exists, and the
most economical way of providing the needed protection.

J.6.3   C2 SECURITY REQUIREMENTS - DoD 5200.28-STD

DISCRETIONARY ACCESS CONTROL. Restrict access to objects (e.g., Hies) based on
the identity of individuals or defined groups of individuals, to protect objects
from unauthorized access and to limit propagation of access rights.

OBJECT REUSE. Eliminate all residual data from a medium (page frame, disk
sector, magnetic tape) before reassignment of that medium from one subject to
another subject.

IDENTIFICATION AND AUTHENTICATION. Identify each individual user of the system
prior to allowing user activity on that system. Establish protective mechanisms
(e.g., passwords) to authenticate the user's identity and to associate this
identity with all auditable actions taken by that user. Authentication data is
to be protected so that it cannot be accessed by any unauthorized user.
Individual accountability is to be enforced by providing the capability to
uniquely identify each individual system user.

AUDIT. Create and maintain an audit trail so that all actions affecting the
security of a system can be traced to the responsible party based on individual
identity. The system must also protect the audit information from modification
or unauthorized access or destruction. The following events must be recorded:

        -       use of identification and authentication mechanisms;

        -       introduction of objects into a user's address space, e.g., file
                open, program initiation deletion of objects

        -       actions taken by computer operators and system administrators
                and/or system security officers, and other security relevant
                events.

        For each recorded event, the audit record shall identify:

        -       date and time of the event

        -       user ID and password

        -       type of event

        -       success or failure of the event



                                     J.6 - 2

<PAGE>   74

        For identification and authentication events, the origin of request,
        e.g., terminal ID), shall be included in the audit record. For events
        that introduce an object into a user's address space, and for object
        deletion events, the audit record shall include the name of the object.
        The ADP system administrator shall be able to audit selectively the
        actions of any one or more users based on individual identity.

SYSTEM ARCHITECTURE. Create and maintain a domain for execution to protect the
Trusted Computing Base (TCB) from external interference or tampering, so that
the TCB may protect its resources via access controls and audit trails.

SYSTEM INTEGRITY. Provide hardware/software features that will validate the
correct operation of the hardware/software/firmware elements of the TCB.

SECURITY TESTING. Test security protection mechanisms to confirm that they work
as claimed in the system documentation. Search for obvious flaws that would
enable bypass of the security mechanisms, violation of resource isolation, and
unauthorized access to the audit or authentication data.

SECURITY FEATURES USERS GUIDE. Prepare a section in the user documentation
describing the protection mechanisms provided by the TCB, guidelines on their
use, and how they interact with one another.

TRUSTED FACILITY MANUAL. Prepare documentation presenting the cautions about
functions and privileges needing to be controlled when running a secure
facility, as well as procedures for examining and maintaining audit files.
Provide a detailed audit record structure for each type of audit event.

TEST DOCUMENTATION. Prepare documentation that describes the test activities and
results of the security mechanisms functional testing.

DESIGN DOCUMENTATION. Make available the manufacturer's documentation that
describes their philosophy of protection and how it is translated into the TCB,
and if distinct TCB modules exist, the description of the interfaces between
these modules.

J.6.4   FREEDOM OF INFORMATION ACT (FOIA) REQUIREMENTS - DoD 5400.7-R

FOR OFFICIAL USE ONLY. Where sensitive unclassified information meets the
criteria of FOIA Exemptions (exemptions 2 through 9), mark and safeguard the
information as "FOR OFFICIAL USE ONLY," as prescribed in Chapter IV, DoD
5400.7-R.

J.6.5   PRIVACY ACT PROGRAM REQUIREMENTS - DoD 5400.11

PRIVACY PROGRAM GENERAL REQUIREMENTS. Establish safeguards to ensure that
records in every system of records that contains personal information covered by
DoD 5400.7-R, are marked and protected as "FOR OFFICIAL USE ONLY."

PRIVACY PROGRAM ADMINISTRATIVE REQUIREMENTS. Establish administrative safeguards
to ensure records in every system of records are protected from unauthorized
disclosure or alteration and that their confidentiality is protected. Safeguards
include measures to mark and protect information, media and computer resources
subject to the DoD Privacy Program; recovery procedures to ensure data
integrity; and computer security training.

PRIVACY PROGRAM PHYSICAL REQUIREMENTS. Establish physical safeguards to ensure
records in every system of records are protected from identified threats that
could result in unauthorized access or alteration and that their confidentiality
is protected. Safeguards include access controls to areas that contain personal
information; protection of on-line devices that directly link to ADP systems
that contain personal information; and appropriate disposal techniques for paper
records. (Paragraph D, Appendix A, DoD 5400.11-R)



                                     J.6 - 3

<PAGE>   75

PRIVACY PROGRAM TECHNICAL REQUIREMENTS. Establish technical safeguards to ensure
records in every system of records are protected from unauthorized disclosure or
alteration and that their confidentiality is protected. Safeguards include
encryption of sensitive unclassified information (only if a comprehensive risk
assessment indicates that it is a cost-effective measure); complete removal of
residual data from magnetic media; control access by dial-up devices via
computer-verified passwords; and controls to assure that passwords grant access
only to data elements required, and no more. (Paragraph E, Appendix A, DoD
5400.11-R)

PRIVACY PROGRAM RISK ASSESSMENT REQUIREMENTS. Conduct a formal risk assessment
for ADP installations that process unclassified personal information to
safeguard against the likelihood of compromise or threats to the information
contained within the installation. This requirement includes installations with
terminals and devices having access to ADP facilities. A formal risk assessment
shall be conducted at the beginning of the design phase of each new unclassified
ADP installation, or for each existing unclassified ADP installation that will
begin processing personal data on a regular basis. The assessments shall be
reconducted every 5 years or whenever a change takes place within tile
installation that warrants this activity. (Paragraph H, Appendix A, DoD
5400.11-R)

J.6.6   LIFE CYCLE MANAGEMENT REQUIREMENTS - DoD 8120.1

LIFE CYCLE MANAGEMENT REQUIREMENTS. Incorporate operational requirements for
security in all AIS programs (paragraph D.2, DoDD 8120.1). Include adequate
internal controls in AIS planning and design to provide reasonable assurance

VACATION: Two weeks paid vacation after 1 year if service with a contractor or
successor; 3 weeks after 5 years; 4 weeks after 15 years. Length of service

4.174)

1/      Does not apply to employees in a bona fide executive, administrative, or
professional capacity as defined and delineated in 29 CFR 541. (See 29 CFR
4.156)

2/      APPLICABLE TO WEATHER OBSERVERS ONLY - NIGHT PAY & SUNDAY PAY: If you
work at night as a part of a regular tour of duty, you will earn a NIGHT
DIFFERENTIAL and receive an additional 10% of basic pay for any hours worked
between 6 p.m. and 6 a.m. If you are a full-time employee (40 hours per week)
and Sunday is part of your regularly scheduled workweek, you are paid at your
rate of basic pay plus a Sunday premium of 25% of your basic rate for each hour
of Sunday work which is not overtime (i.e. occasional work on Sunday outside the
normal tour of duty is considered overtime work).

                                UNIFORM ALLOWANCE

If employees are required to wear uniforms in the performance of this contract
(either by terms of the Government contract, by the employer, by the state of
local law etc.), the cost of furnishing such uniforms and maintaining (by
laundering or dry cleaning) such uniforms is an expense that may not be borne by
an employee where such cost reduces the hourly rate below that required by the
wage determination. The Department of Labor will accept payment on accordance
with the following standards as compliance:

The contractor or subcontractor is required to furnish all employees with an
adequate number of uniforms without cost or to reimburse employees for the
actual cost of the uniforms. In addition, where uniform cleaning and maintenance
is made the responsibility of the employee, all contractors and subcontractors
subject to this wage determination shall (in the absence of a bona fide
collective bargaining agreement providing for a different amount, or the
furnishing of contrary affirmative proof as to the actual cost), reimburse all
employees for such cleaning and maintenance at a rate of $4.25 per week (or $.85
cents per day). However, in those instances where the uniforms furnished are
made of "wash and wear" material, may be routinely washed and dried with other
personal garments, and do not require special treatment such as dry cleaning,
daily washing, or commercial laundering in order to meet the cleanliness or
appearance standards set by the terms of the Government contract, by the
contractor, by law, or by the nature of the work. there is no requirement that
employees be reimbursed for uniform maintenance costs.

Source of Occupational Titles and Descriptions:

The duties of employees under job tides listed are those described in the
"Service Contract Act Directory of Occupations," Fourth Edition, January 1993,
as amended by the Second Supplement, dated August 1995, unless otherwise
indicated. This publication may be obtained from the Superintendent of
Documents, at 202-783-323g, or by writing to the superintendent of Documents,
U.S. Government Printing Office, Washington, D.C. 20402. Copies of specific job
descriptions may also be obtained from the appropriate contracting officer.

REQUESTS FOR AUTHORIZATION OF ADDITIONAL CLASSIFICATION AND WAGE RATE (Standard
Form 1444 (SF 1444)

Conformance Process:

The contracting officer shall require that any class of service employee which
is not listed herein and which is employed under contract (i.e., the work to be
performed is not performed by any classification listed in the wage
determination), be classified by the contractor so as to provide a reasonable
relationship (i.e., appropriate level of skill comparison) between such unlisted
classifications and the classifications listed in the wage determination. Such
conformed classes of employees shall be paid the monetary wages and furnished
the fringe benefits as are determined. Such conforming process shall be
initiated by the contractor prior to the performance of contract work by such
unlisted class(es) of employees. The conformed classification, wage rate, and/or
fringe benefits shall be retroactive to the commencement date of the contract.
(See section 4.6 (C) (vi). When multiple wage determinations are included in a
contract, a separate SF 1444 should be prepared for each wage determination to
which a class(es) is to be conformed.

The process for preparing a conformance request is as follows:

1)      When preparing the bid, the contractor identifies the need for a
        conformed occupation(s) and computes a proposed rate(s).

2)      After contract award, the contractor prepares a written report listing
        in order proposed classification title(s), a Federal grade equivalency
        (FGE) for each proposed classification(s), job description(s), and
        rational for proposed wage rate(s), including information regarding the
        agreement or disagreement, if the authorized representative of the
        employees involved, or where there is no authorized representative, the
        employees themselves. This report should be submitted to the contracting
        officer no later than 30 days after such unlisted class(es) of employees
        performs any contract work.

3)      The contracting officer reviews the proposed action and promptly submits
        a report of the action, together with the agency's recommendations and
        pertinent information including the position of the contractor and the
        employees, to the Wage and Hour Division, Employment Standards
        Administration, U,S. Department of Labor, for review. (See section 4.6
        (b) (2) of Regulations 29 CFR Part 4).

4)      Within 30 days of receipt, the Wage and Hour Division approves, modifies
        of disapproves the action via transmittal to the agency contracting
        officer, or notifies the contracting officer that additional time will
        be required to process the request.

5)      The contracting officer transmits the Wage and Hour decision to the
        contractor.

6)      The contractor informs the affected employees.

Information required by the Regulations must be submitted of SF 1444 or bond
paper.

When preparing a conformance request, the "Service Contract Act Directory of
Occupations" (the Directory) should be used to compare job definitions to insure
that duties requested are not performed by a classification already listed in
the wage determination. Remember, it is not the job title, but the required
tasks that determine whether a class is included in an established wage
determination. Conformances may not be used to artificially split, combine, or
subdivide classifications listed in the wage determination

<PAGE>   7

Documentation during the term of this Agreement, subject to the terms and
conditions set forth herein. However, in the event that the architecture of the
MPOWER 6000 system, operating on the IBM Rs/6000 platform, results in
significant degradation of system performance, due solely to the segregation of
Customer's clients' files, Customer is required to acquire and operate a second
Rs/6000 in order to meet the processing requirements of the clients set forth in
Schedule A, then Customer may operate the MPOWER 6000 Software on the second CPU
without payment of an additional license fee.

          (b)  MPOWER shall prepare and provide Customer one (1) copy of the
current Documentation for the MPOWER Software using electronic media and update
same as required due to enhancements, upgrades, error correction or other
changes made by MPOWER to the MPOWER Software. When MPOWER has produced
Documentation in HTML format, which is expected to be available by the end of
1997, MPOWER will provide a copy of the Documentation to Customer in such
format.

     2.2  Payment. In consideration of the License, Customer shall timely pay
the ILF, the MF and the Supplemental Services Fees in accordance with Schedule
C.

     2.3  Scope of Use.

          (a)  Customer, shall use the MPOWER Software and Documentation solely
for its own use as a provider or administrator of managed health care and/or
other insurance services to Customer clients and the Members of its Related
Parties, including a health maintenance organization which may be established by
Customer, solely as expressly set forth herein, pursuant to the terms herein and
not for the benefit of any other entity, and further subject to the Related
Party restrictions in the License granted. The initial Customer clients which
will be processed by Customer are Community Premier Plan, Bridgeport Health
Plan, Fidelis Care Health Plan, Suffolk County Health Plan and Universal Health
Plan, except that Universal Health Plan will not be subjected to the
implementation terms and incentives set forth in this Agreement. If Customer
establishes a health maintenance organization or insurance company, MPOWER's
implementation for such entities shall be subject to fees as Supplemental
services.

                                      -6-
<PAGE>   8

          (b)  Customer shall have the right to provide the use of certain
limited functions and features of the MPOWER Software, to its clients for which
Customer provides administration services, and to providers of health care
services, subject to the confidentiality restrictions set forth in Section 13.

          (c)  Customer shall not copy the MPOWER Software or permit same to be
copied, except for production copies for use within the restrictions of the
License granted herein, and for a reasonable number of backup and test copies:
(i.) for the specific data center where the MPOWER Software will be installed
where Customer is performing Customer Processing, (ii.) for testing and
modification of the MPOWER Software (pursuant to Section 2.7), and (iii.)for

number of copies of the User Documentation solely for Customer's internal use
and for distribution to Related Parties and Non-Related Parties pursuant to
Section 13.2, not to exceed one (1) copy per workstation, and only if the
original copyright and other proprietary rights notices are preserved.

          (e)  MPOWER Software used for Customer Processing may be temporarily
transferred to backup equipment owned by Customer or by a third party provider
of disaster recovery services and used thereon only for so long as the Customer
site is inoperative. The use of such third party provider of disaster recovery
services shall not require the consent of MPOWER provided such provider agrees
to be bound by the confidentiality restrictions set forth herein, and is not a
competitor of MPOWER. Simultaneous use of more than the authorized number of
copies of the MPOWER Software is expressly prohibited.

          (f)  Customer shall not modify the MPOWER Software or the
Documentation (except as set forth below), nor translate, or adapt the MPOWER
Software or the Documentation (except as set forth below), in any way or use it

presentation of the MPOWER Software as follows: Customer will initially present
a requested change to MPOWER and if MPOWER wishes to make the change, MPOWER
will submit a quote to Customer for the work and if the Customer accepts the
proposal, a Work Order will be developed for the project. If Customer declines
MPOWER's proposal, Customer may propose to MPOWER that Customer develop the
modification. Customer will submit a plan for such modification to MPOWER and if
MPOWER accepts such plan, and if the Customer developed modification
successfully passes acceptance testing, then MPOWER will warrant the performance
of the modification. If MPOWER elects not to accept the proposed modification or
if an accepted proposal fails to pass acceptance, or if Customer modifies GUI
presentation without the consent of MPOWER, MPOWER shall have no obligation to
warrant or support such Customer developed modifications.

Customer may modify copies of the Documentation limited to the purpose of
integrating Customer's internal operating procedures and work flows into the
content relating to the operation of MPOWER. All Customer duties to maintain the
confidentiality of MPOWER Software and Documentation shall remain in full effect
for all MPOWER Documentation incorporated into such Customer documents. Customer
shall maintain an unaltered copy of the MPOWER Documentation which shall be the
baseline Documentation of the MPOWER System.

Except as set forth in Section 7.2 with respect to the Shelf Version and as set
forth in this Section 2.3 (f), MPOWER shall not be responsible for the

installs or attempts to install software, other than MPOWER Software, which
interfaces with the MPOWER Software in a manner which is inconsistent with
MPOWER Standard Interface Specifications, or writes to any data files maintained
by the MPOWER Software. Customer shall be solely responsible for the results of
such modifications or interfaces, including the integrity of data used or
generated by the MPOWER Software. In the event that Customer makes a
modification or enhancement to the MPOWER Software, and it is subsequently
determined that such modification or enhancement was the cause of a
Nonconformity in the MPOWER Software, then MPOWER shall be reimbursed at the
Supplemental Service Fees rates set forth in Schedule C for the

                                      -8-
<PAGE>   10

time spent in determining that such modification or enhancement was the cause of
the Nonconformity, and, if MPOWER agrees to provide Supplemental Services
support as specified on a Work Order to correct such Nonconformity, then MPOWER
shall be reimbursed at the Supplemental Service Fee rates set forth in
Schedule C.

     2.4  General System Enhancements. In consideration of the ILF and MF,
MPOWER shall provide to Customer General System Enhancements, if and when such
General System Enhancements are made available to licensees of the MPOWER
Software generally, except as otherwise provided in Schedule C. Any General
System Enhancements supplied to Customer by MPOWER shall become part of, and
subject to, this Agreement and License. MPOWER shall only provide General System
Enhancements for the then most current Release of the MPOWER Software. In
addition, MPOWER agrees also to provide support for the one prior Release
immediately preceding the most current Release of the MPOWER Software and to
provide support for any other Releases for up to one (1) year from the Release
Date of such other Releases. During any applicable support period, support for
any such prior Release of the MPOWER Software that has been replaced or modified
by General System Enhancements or by a subsequent Release shall be limited to
correction of identified and reproducible defects in the Shelf Version of such
prior Release from the published specifications therefor. MPOWER shall not be
obligated to provide General System Enhancements for any Release other than the
most current Release. Any additional MPOWER Services provided in connection with
an older Release of the MPOWER Software shall be provided as Supplemental
Services.

     2.5  Upgrades in Operating System. In the event the operating system for
the platform on which Customer operates MPOWER is upgraded by the developer of
such operating system, MPOWER will within one year of the release of said
upgrade test the performance of the MPOWER Software on such operating system.

     2.6  Correction of Nonconformities. In consideration of the ILF and MF, and
subject to the terms of this Agreement, upon written notification by Customer of

interdependent relationships, and to define for its own purposes such data
variables, logic rules and system functions to the MPOWER Software in such a way
that the MPOWER Software will provide the functionality desired by Customer.
Customer acknowledges that it has or will hire and will maintain on its staff
personnel who are able to understand and define such data variables, logic
rules, system functions and interdependent relationships. Customer further

maintenance of these data variables,

                                      -11-
<PAGE>   13

logic rules and system functions resides with Customer and not with MPOWER,

Supplemental Services Fees. Notwithstanding the foregoing, nothing herein shall
relieve MPOWER of responsibility for the assistance that it may provide to
Customer hereunder.

     5.2  Testing Customer acknowledges that it will undertake testing of the
MPOWER Software and of the basic functionality and interdependency of its
customer-defined data variables, logic rules and system functions as set forth

printed or into which files or programs on Customer controlled computers such
files are to be downloaded and manipulated, at Customer's own initiative,
responsibility and risk. Customer hereby acknowledges responsibility for
generally controlling all aspects related to the production, distribution and
control of such outputs. Customer further acknowledges that the accuracy of
Customer's database within the MPOWER Software and the accuracy of the several
outputs of the MPOWER Software, including but not limited to, outputs that
control the billing, receipt or expenditure of moneys, will be dependent on the
accuracy and use of the data variables, logic rules, system functions and
Customer data input into the MPOWER Software by Customer and verified by
Customer. Notwithstanding the

                                      -12-
<PAGE>   14

foregoing, nothing herein shall relieve MPOWER of responsibility for

access to the production data including but not limited to data files, data
bases, run time setups and source and load libraries as they existed at the time
of the creation of the inaccurate or incomplete report or output, Customer shall
be deemed to have waived its rights and assumed all risks with respect thereto;

connection with the authorized use of the MPOWER Software hereunder) procedure
manuals and documentation used by Customer personnel in connection with the
MPOWER Services hereunder;

          (f)  Train applicable Customer. personnel to properly prepare input

Customer data must be corrected, recreated, restored or reprocessed due to the
sole fault or negligence of Customer, its employees or agents, or by a breach by
Customer of any of its obligations hereunder, MPOWER will do so as Supplemental
Services, and in such event Customer shall reimburse MPOWER for any costs
incurred by MPOWER in correcting, recreating, restoring or reprocessing such

efforts, but in no event shall such process exceed fifteen (15) days. The above
cycle shall be repeated as is necessary. A deliverable shall be deemed accepted
by Customer if either:

          (a)  Customer notifies MPOWER in writing of its acceptance and the
acceptance date shall then be the date of such notice;

          (b)  Customer fails to notify MPOWER in writing within the applicable
time period of any material defect in the deliverable and the acceptance date
shall then be the last day of said period; or

          (c)  Customer places in productive use any portion of the deliverable
and the acceptance date shall be June 1, 1997, unless accepted earlier under
paragraphs (a) or (b) above.

     Customer agrees that it will test any modifications or enhancements made by
MPOWER for Customer as a part of the initial Implementation. The version and
release of the MPOWER Software so accepted by Customer shall be deemed the
current Shelf Version. Customer and MPOWER shall maintain copies of each Shelf
Version. The obligation of MPOWER to maintain any enhancements or modifications
made specifically for Customer that are not part of either General System
Enhancements or a Release shall be specified in the Work Order that authorizes
such enhancements or modifications or in a subsequent Work Order.

     6.2  Delivery of Releases, Modifications and Enhancements Subsequent to
Initial Implementation: For all deliverables, including the MPOWER Software and
General System Enhancements and Customer-specific enhancements and modifications
provided pursuant to an applicable Work Order, Customer shall, within thirty
(30) days of receipt of the deliverable, review and, if applicable, test the
deliverable and approve it or notify MPOWER in writing of non-approval,
documenting in reasonable detail any and all material defects in the deliverable
which prevent it from conforming to the Documentation or specifications
therefor, as applicable. Work Orders for Customer enhancement requests will
include specification of an acceptance test period

                                      -15-

that is mutually agreed to by Customer and MPOWER and which shall be reflective
of the estimated size and complexity of the deliverable specified by the Work
Order. MPOWER shall, upon receipt of such notice, use its best efforts to
correct any such material failures and shall notify Customer of its completion
thereof. Customer shall, after receipt of said notice, review the deliverable
and report. Customer shall do so promptly using diligent efforts, but in no
event shall such process exceed fifteen (15) days. The above cycle shall be
repeated as is necessary. A deliverable shall be deemed accepted by Customer if
either:

          (a)  Customer notifies MPOWER in writing of its acceptance and the
acceptance date shall then be the date of such notice;

          (b)  Customer fails to notify MPOWER in writing within the applicable
time period of any material defect in the deliverable and the acceptance date
shall then be the last day of said period; or

          (c)  Customer places in productive use any portion of the deliverable
and the acceptance date shall then be the first day of such productive use.
Productive use for purposes of the foregoing shall not include the use by
Customer of the MPOWER Software in a parallel processing environment where
Customer is utilizing the MPOWER Software to process a limited number of Members
during a reasonable period of time for the purpose of testing the MPOWER
Software.

     Customer agrees that it will so test any modifications or enhancements made
by MPOWER for Customer under an applicable Work Order and made part of a Release
and all General System Enhancements. The version and release of the MPOWER
Software so accepted by Customer shall be deemed the current Shelf Version.
Customer and MPOWER shall maintain copies of each Shelf Version. The obligation
of MPOWER to maintain any enhancements or modifications made specifically for
Customer that are not part of either General System Enhancements or a Release
shall be specified in the Work Order that authorizes such enhancements or
modifications or in a subsequent Work Order.

7.   WARRANTIES

     7.1  MPOWER warrants that it either owns the rights to the MPOWER Software
or has the right to grant the license to Customer herein, and that it either
owns or has licensed in the manner contemplated by this Agreement any other
software used in the provision of the MPOWER Services to Customer, including but

legal fees) directly arising out of any such claim that the Shelf Version of the
MPOWER Software infringes upon or violates any United States patents,
copyrights, trademarks, trade secrets or other proprietary, contractual or
intellectual property rights of any third party; provided, however, Customer
must send MPOWER written notice of any claim relating to such infringement
promptly after Customer receives notice of the same and Customer fully
cooperates, at MPOWER's expense, in the defense of any such claim. Following

written notice to Customer and at MPOWER's expense, either: (a) procure for
Customer the right to continue using such MPOWER Software; (b) replace or modify
same so that it becomes non-infringing; or, (c) grant to Customer a refund of

depreciation upon its return to MPOWER if neither (a) nor (b) are reasonably
possible, in MPOWER's sole discretion. The foregoing states the entire liability
of MPOWER and the sole remedy of Customer with respect to any infringement or
claimed infringement by the MPOWER Software.

or allegation (i.) asserted by a parent, subsidiary or affiliate of Customer or
any Related Party, (ii.) resulting from Customer's additions to, changes in, or
enhancements or modifications of the MPOWER Software, (iii.) resulting from
Customer's use of the MPOWER Software in

combination with non-MPOWER Software, or (iv.) resulting from Customer's misuse
of the MPOWER Software.

     7.2  MPOWER warrants that the Shelf Version of the MPOWER Software will
function as set forth in MPOWER's User Documentation, including all MPOWER
developed updates and enhancements thereto. Upon receipt of Customer's notice
given pursuant to Section 16.1, MPOWER and Customer shall cooperate to attempt
to duplicate the problem on the Shelf Version of the MPOWER Software. If the
problem can be duplicated, MPOWER's sole obligation under this warranty and
Customer's sole remedy shall be for MPOWER to comply with the service
obligations set forth in Section 4. If the problem cannot be duplicated,
MPOWER's warranty shall not apply and MPOWER shall have no obligation to remedy
the cited defect. MPOWER covenants and warrants that all improvements and
enhancements of the MPOWER Software provided by MPOWER will be compatible with,
and will not materially diminish the features or functions of, or the
specifications of the Shelf Version of the MPOWER Software, and that the Shelf
Version of the MPOWER Software will be compatible with the equipment described
in the Documentation. MPOWER warrants that User Documentation shall reflect the
operation of the MPOWER Software, and MPOWER shall, at no additional cost to
Customer, correct any User Documentation that does not conform to this warranty.

THOSE WARRANTIES EXPRESSLY SET FORTH IN THIS SECTION 7. MPOWER SPECIFICALLY

9.   FEES AND CHARGES

     9.1  Fees and Charges. The Fees for the MPOWER License and Services are
described in Schedule C attached hereto.

     9.2  Timeliness of Payment. Customer will pay the ILF in accordance with
the schedule set forth in Schedule C. Any other sum due MPOWER hereunder for
which a time for payment is not otherwise specified will be due and payable
within thirty (30) days after the due date of an invoice therefor from MPOWER.
All payments shall be in U.S. dollars. Each MPOWER invoice shall reference this
Agreement and the applicable Work Order. If Customer fails to pay any amount due
and not reasonably disputed by Customer within forty-five (45) days from its due
date, late charges of one and one half percent (1.5%) (or the maximum allowable
under applicable law, whichever is lower) per month shall also become payable by
Customer to MPOWER. if Customer fails to pay, when due, any amount payable
hereunder and not reasonably disputed by Customer or fails to fully perform its
obligations hereunder, Customer agrees to pay, in addition to any amount past
due, plus interest accrued thereon, all reasonable expenses incurred by MPOWER
in enforcing this Agreement including but not limited to all expenses of any
legal proceeding related thereto and all reasonable attorneys' fees incurred in
connection therewith. No failure by MPOWER to request any such payment or to
demand any such performance shall be deemed a waiver by MPOWER of Customer's
obligations hereunder or a waiver of MPOWER's right to terminate this Agreement.

     9.3  Taxes. There will be added to any charges under this Agreement, and
Customer will pay to MPOWER, amounts equal to any taxes, however designated or
levied, based upon such charges, or upon this Agreement or the services or
materials provided hereunder, or Customer's use thereof, including federal,
state and local sales, use, privilege or excise taxes based on gross revenue,
and any taxes or amounts in lieu thereof paid or payable by MPOWER in respect of
the foregoing, but excluding any franchise taxes, taxes based on the gross
income or adjusted gross income of MPOWER, and employee withholding, FICA and
other taxes relating to MPOWER personnel performing services hereunder. Such
taxes will be itemized separately from service fees or charges for materials and
products on the invoice. In the event that MPOWER collects any such taxes, as
described in the first sentence of this Section 9.3, MPOWER acknowledges its

                                      -20-
<PAGE>   22

responsibility to pay such collected taxes to the appropriate taxing authority

10.  OTHER PROVISIONS

     10.1 Independent Contractor. MPOWER, its agents and employees, in
performing their respective obligations under this Agreement, are acting only as
independent contractors of Customer, and not as officers, employees or agents of
Customer, and the rights and responsibilities of the parties shall be determined
accordingly.

     10.2 Force Majeure. Each party hereto shall be excused from performance
hereunder (except for payment obligations) for any period and to the extent
that it is prevented from performing any services pursuant hereto, in whole or
in part, as a result of delays caused by the other party or an act of God, war,
civil disturbance, court order, labor dispute of the other party or any third
party, or other cause beyond its reasonable control and which it child not have
prevented by reasonable precautions, and such nonperformance shall not be a
default hereunder or a ground for termination hereof. In the event that either
party is excused from performance hereunder pursuant to this Section, then that
party shall take all reasonable actions to resume, or provide alternative
performance of its obligations hereunder as soon as feasible.

11.  DISPUTE RESOLUTION AND TERMINATION

     11.1 Dispute Resolution. In the event of a dispute between the parties
arising out of or relating to this Agreement, the parties shall meet and attempt
in good faith resolve the dispute. Initially, disputes will be handled by the
MPOWER Account Executive and the Information Services Director, or his/her
equivalent, of Customer, and if they are unable to reach a resolution, the
dispute will be presented to the Chief Operating Officer of MPOWER and the
President of Customer for resolution. If the matter has not been resolved
pursuant to the aforesaid mediation procedure within sixty (60) days of the
commencement of such procedure (which period may be extended by mutual
agreement), the controversy shall be settled by arbitration pursuant to the
rules of the American Arbitration Association for commercial arbitration, by a
panel of three (3) arbitrators knowledgeable in the computer area. The
arbitration

                                      -21-
<PAGE>   23

shall be governed by the United States Arbitration Act, 9 U.S.C. Sec. 1-16, and
judgment upon the award by the arbitrator may be entered by any court having
jurisdiction thereof. The place of arbitration shall be New York City, New York.
Each party shall pay its own cost and expenses.

     The formation and performance of this Agreement shall be governed and
interpreted by the laws of the State of New York. Either party shall be entitled
to seek injunctive relief against the other in a court having competent
jurisdiction upon a disclosure or threatened disclosure of any Confidential
Information without a requirement that the moving party prove irreparable harm
or the posting of a bond.

     11.2 Termination for Cause. In the event either party materially breaches
any term or provision of this Agreement and such breach remains uncured for
thirty (30) days following receipt of written notice from the other party of
such breach; or if any proceedings under the bankruptcy law or any state or
local insolvency statutes are filed against Customer or MPOWER which remain
undismissed or undischarged for a period of ninety (90) days; or if either party
files a petition in voluntary bankruptcy or seeks relief under any bankruptcy
law or any state or local insolvency statutes; or if either party consents to
the appointment of or taking possession by a receiver, trustee or liquidator of
itself or its property; or if either party makes an assignment for the benefit
of creditors; then the nondefaulting party may terminate, at its option, this
Agreement and License hereunder, and/or have recourse to any other right or
remedy available at law or in equity.

     11.3 Outstanding Amounts. Termination of this Agreement shall entitle
MPOWER to payment and Customer shall be obligated to pay for the provisions of
any and all undisputed and verified MPOWER Services rendered by MPOWER under
this Agreement prior to the date of such termination, and all outstanding fees
and Expenses incurred prior to the date of termination.

     11.4 Customer Data. In the event that either party terminates this
Agreement, Customer retains ownership of all Customer membership data and all
other Customer data defined in the MPOWER System. MPOWER shall return same to
Customer at the time of termination in MPOWER's standard tape record format. Any
programming, analysis or consulting services requested by

                                      -22-
<PAGE>   24

Customer to provide data in formats other than MPOWER's standard tape record
format shall be provided as Supplemental Services.

     11.5 MPOWER Software. Unless otherwise provided in this Agreement, Customer
agrees that upon termination of this Agreement, the License granted hereunder
shall also terminate and Customer shall cease using the MPOWER Software and
shall return to MPOWER or destroy, within thirty (30) days after such
termination, the original and all copies of such MPOWER Software and
Documentation. Except for termination resulting from the material breach on the
part of Customer, including without limitation, breach of its Confidentiality
obligations or failure to timely make any payment hereunder, Customer shall be
permitted to continue to use the MPOWER Software pursuant to all the terms and
conditions set forth in this Agreement for up to a maximum of six (6) months
following such termination for the sole purpose of transitioning Members to an
alternate processing software, provided (i.) Customer remains obligated to pay
MF during such period; (ii.) MPOWER has no further obligations to provide Core
Services, new Releases, fixes to Nonconformities or Critical Failures, and
(iii.) the MPOWER Software is no longer warranted. If Customer destroys the
MPOWER Software, all copies thereof and Documentation, within thirty (30) days
of such destruction an officer of Customer shall certify to MPOWER in writing
that the MPOWER Software and all copies and Documentation thereof have been
destroyed. Due to the nature of the MPOWER Software and the need for its
protection as a trade secret and confidential proprietary information, time is
of the essence in its return or destruction, and in the event of Customer's
failure to do so within the time provided herein, Customer agrees that MPOWER
shall be entitled to obtain injunctive relief to require such return or
destruction and reasonable attorneys' fees and costs incurred in obtaining such
injunctive relief.

     12.  LAW GOVERNING AGREEMENT

State of New York without reference to principles of conflicts of laws.

                                   Schedule B

                       Definition of Supplemental Services

B.1. Supplemental Services: Supplemental Services may include as applicable (i.)
conversion services to convert Customer data; (ii.) System Setup such as the
establishment of benefit plans, pricing information, tracking information,
capitation rules, procedure and diagnosis code files and fund accounting and
billing rules; (iii.) services for modifying the MPOWER Software for
enhancements and modifications; (iv.) training beyond that set forth in Schedule
A; (v.) consulting services; (vi.) the efforts required to be put forth by
MPOWER to respond to the excessive or inappropriate use of the MPOWER Help Desk
by Customer for issues resulting from the lack of adequately trained Customer
personnel or from the lack of use or inadequate utilization of the Documentation
by Customer ; and (vii.) project coordination and management for the above
Supplemental Services. All suck Supplemental Services shall be described in an
applicable Work Order and shall be undertaken by MPOWER only pursuant to a Work
Order, a specimen of which is set forth in Schedule H.

For services requested by Customer which are beyond the scope of the services
generally contemplated hereunder, for special circumstances, or if the
geographic location in which any MPOWER services are to be provided for Customer
demands higher labor or resource costs, MPOWER will provide Customer with
written notice, and MPOWER reserves the right to propose a new fee structure or
different rates, which fee structure or rates will be detailed in the
appropriate Work Order.

B.2. Enhancements and Modifications Under Work Orders: Pursuant to this Schedule
and the applicable Work Order, Customer may identify enhancements or
modifications which it desires to have MPOWER make to the MPOWER Software, such
as integration to other software systems, modifications for legal requirements,
and other functional enhancements. Customer shall be responsible for providing
to MPOWER a description of the changes which Customer requests to be made in the
MPOWER Software. MPOWER shall have the right to design any Customer requested
enhancements or modifications in a way which, in MPOWER's reasonable opinion,

                                      B-1
<PAGE>   39

will not adversely affect the MPOWER Services or the structure or performance of
the MPOWER Software or will have general applicability. In the event MPOWER
agrees to provide such enhancements or modifications to the MPOWER Software,
such enhancements or modifications shall be owned by MPOWER and licensed to
Customer as part of the MPOWER Software subject Section 2 of the Agreement.
Resources utilized by MPOWER in providing services pursuant to any such requests
will be detailed in applicable Work Orders. If MPOWER declines to modify
presentation of the MPOWER Software, Customer may have the option to modify such
GUI presentation only, subject to the terms and conditions set forth in Section
2.3 (f) of the Agreement.

B.3. Data Integrity: Customer acknowledges that, although MPOWER may, as part of
Supplemental Services, perform certain conversion tasks (for which MPOWER shall
be responsible), including development of files and programs for the conversion
of Customer data into formats for the MPOWER Software, the quality and integrity
of all Customer data provided to MPOWER, and the results obtained or resulting
from poor or inaccurate data are solely Customer's responsibility.

B.4. Access: In order for the Supplemental Services to be completed in a timely
and successful manner, Customer shall provide MPOWER with such access to
applicable information and key Customer personnel as MPOWER may reasonably
request from time to time during the period the Supplemental Services are being
performed. In connection with the Supplemental Services, MPOWER will be entitled
to submit various materials, including time schedules, business requirements,
specifications, and test results, for Customer's review, comment, sign-off, or
approval. Customer will respond to each such request as soon as reasonably
practicable, and, in any event, in a time frame consistent with the applicable
project plan, and shall not unreasonably withhold any sign-off or approval
requested by MPOWER.

B.5. Help Desk: MPOWER shall provide a "Level Two" Help Desk to answer Customer
questions and solve Customer problems for acceptance testing and production
activities as further described herein. (Questions that are training related, or
answers to which can be found in the User Documentation, or that are related

                                      B-2
<PAGE>   40

to initial setups and definitions should be referred to the MPOWER
implementation support team.) The Help Desk is staffed 8:00 a.m. to 5:00 p.m.,
Mountain Time, Monday through Friday. Calls to the Help Desk outside of these
hours are rolled over either to MPOWER Operations or pager response. An Inward
WATS number (currently 1-800-993-3677) is available for Help Desk calls at no
charge to the Customer. Calls to the Help Desk that represent problems related
to the MPOWER Software or MPOWER System are assigned a Problem Number and
entered into the MPOWER Problem Reporting and Tracking System, where current
status is available for reporting back to the Customer.

     A "Level Two" Help Desk call is a call from the Customer's internal Help
     Desk seeking support for questions and problems for production activities
     that the Customer's Help Desk was not able to resolve on its own (each a
     "Service Call").

     MPOWER represents that Service calls will be logged and responded to
     as-follows:.

A.   Severity Level/Priority: 1

     Definition: A Critical Failure.

     Support: MPOWER will provide telephone support twenty-fours (24) hours per
     day, seven (7) days per week for Severity Level 1 problems.

     Time Frame for Resolution: Service Calls will be responded to by
     knowledgeable MPOWER staff via telephone within thirty (30) minutes of
     receipt of a Service Call between the hours of 8:00 a.m. to 5:00 p.m.,
     Mountain Time, Monday through Friday, and one (1) hour during other
     periods. MPOWER will use its best efforts to provide a resolution of the
     problem (permanent or temporary) within twenty-four (24) hours of receipt
     of the Service Call, or verification by MPOWER of the problem, either
     through replication or receipt by MPOWER of complete documentation from
     Customer needed to resolve the problem -- whichever occurs last. Customer
     shall maintain immediate resource availability during all hours that MPOWER
     is working on a Service Call.

B.   Severity Level/Priority: 2

                                      B-3
<PAGE>   41

     Definition: Production degraded -- defined as a verifiable Nonconformity in
     the Shelf Version of the MPOWER Software (or verifiable failure of the
     MPOWER System hardware, if the problem arises with respect to Remote
     Processing) that does not disrupt critical business processing, but causes
     disruption to normal work flow.

     Support: MPOWER will provide telephone support twenty-fours (24) hours per
     day, Mountain Time, Monday through Friday for Severity Level 2 problems.

     Time Frame for Resolution: Service Calls will be responded to by
     knowledgeable MPOWER staff via telephone within the same working day,
     Monday through Friday, if the Service Call is received prior to 3:00 p.m.
     Mountain Time. Otherwise, if the Service Call is received after 3:00 p.m.
     Mountain Time, the call will be responded to by 10:00 a.m., Mountain Time,
     the next morning, except Saturdays and Sundays. MPOWER will use its best
     efforts to provide a resolution of the problem (permanent or temporary)
     within three (3) business days of receipt of the Service Call; or
     verification by MPOWER of the problem, either through replication or
     receipt by MPOWER of complete documentation from Customer needed to resolve
     the problem -- whichever occurs last.

C.   Severity Level/ Priority: 3

     Definition: Normal response to either non-critical questions or
     non-critical problems. A non-critical problem is defined as a verifiable
     Nonconformity in the Shelf Version of the MPOWER Software (or verifiable
     failure of the MPOWER System hardware, if the problem arises with respect
     to Remote Processing), that does not cause disruption to normal work flow
     or degrade production.

     SUPPORT: MPOWER will provide telephone support from 8:00 a.m. to 5:00 p.m.
     Mountain Time, Monday through Friday, for Severity Level 3 situations.

     Time Frame for Resolution: Service Calls for Severity Level 3 situations
     are handled differently whether the Service Call is a non-critical question
     or a non-critical MPOWER Software or

                                      B-4
<PAGE>   42

     MPOWER System problem. If a non-critical MPOWER Software or MPOWER System
     problem, it will be entered into the MPOWER Problem Reporting and Tracking
     System. MPOWER and the Customer shall jointly prioritize these non-critical
     problems at least weekly up to one year after first production use, and at
     least monthly thereafter. After prioritization, MPOWER shall produce a
     schedule for their resolution.

Within ten (10) working days after month-end, MPOWER will provide reports and
graphs to the customer liaison (see Section 15.2 and 16.1) comparing Service
Call performance against standards for Severity 1, 2, and 3 Service Calls --
both for the month and the year-to-date.

For two successive calendar quarters, beginning with the first calendar quarter
after the initial Implementation Date, the Customer shall be entitled to
unlimited Service Calls from the Customer's help desk to the Help Desk (or its
"after hours" rollover to Operations). Thereafter, Service Calls to the Help
Desk in excess of sixty (60) calls per calendar quarter shall be billed as
Supplemental Services.

Other Customer Requested Services: Customer may request additional Supplemental
Services pursuant to this section subject to Customer's submission of a Work
Order, MPOWER's acceptance of the assignment and subject to the payment of
Supplemental Service Fees set forth in Schedule C.

               monthly Support and Maintenance Fees on a prorated basis for
               increments of [*] members once the total membership exceeds

A work order is the document the Customer uses to authorize MPOWER to perform
Supplemental Services ("Work Order"). Some examples of Supplemental Services are
modifications, enhancements, conversion support, additional training, etc. The
steps in completing a Work Order are as follows:

Step 1. The Customer determines that Supplemental Services are required from
        MPOWER.

Step 2. The Customer, assisted by MPOWER if requested, provides, in writing,
        the functional requirements for the Supplemental Services desired.

Step 3. Provided Customer has provided sufficient information in Step 2, MPOWER
        creates a project plan. (If information is incomplete, Step 2 needs to
        be repeated or expanded upon.) The contents of a typical project plan
        are given below:

                        Contents of Typical Project Plan

        I.      Statement of work, including description of task, goal, scope of
                effort, assumptions/constraints, approach, success factors, and
                risks.

        II.     Term

        III.    Estimated Hours (if applicable)

        IV.     Staffing and Roles

        V.      Schedule and Milestones

        VI.     Deliverables

        VII.    Estimated Non-Personnel Charges (such as, if applicable, but not
                limited to, supplemental computer

                processing usage, telecommunications charges, physical
                materials, special equipment, etc.)

Step 4. Customer reviews project plan. If necessary based on Customer's
        comments, MPOWER revises project plan.

Step 5. MPOWER prepares a Work Order (see sample on the next page) with the
        project plan as an attachment.

Step 6. Customer approves Work Order.

Step 7. Work begins upon receipt by MPOWER of an approved Work Order.

NOTE:   Any change in scope (e.g., a modification or an expansion to the
        functional requirements in Step 2) to an existing Work Order requires a
        new Work Order and a repeat of the above steps.

March 25, 1999

XCARE Technologies, Inc.
Attention: Tammy McLaren
6400 S. Fiddler's Green Circle, Suite 540
Englewood, GO 80111

Sent via fax: 303-488-9705

Dear Tammy,

I am pleased to inform you that Advica Health Resources, Inc would like to
contract with XCARE Technologies to provide Operational Systems Management
Services as outlined in the MOWER Operational Systems Management Addendum - Rev.
2/99. We would like to proceed on the basis that the hardware will remain at our
offices and XCARE would perform their work remotely via the dedicated
communications line. It is understood that in this setup Advica will be
responsible for providing the labor locally to support such activities as
changing backup tapes and having access to the system console m handle such
activities as coordination of hardware troubleshooting and network/security
administration. I have incorporated the changes that we discussed earlier today.

TERM:

Advica would like to modify the term of the agreement slightly. The term calls
for a three year contract with a minimum term of one year with a fee of [*]
per month. This is acceptable. We would want to add the following clauses:

- -  Advica reserves the right to terminate services with a minimum of 90 days
   written notice, recognizing the minimum term of the contract is one year. We
   Understand that resources have to be allocated for this task and believe that
   90 days notice would provide sufficient time to reallocate these resources.

- -  If XCARE does nor meet mutually agreed upon performance standards and does
   not cure deficiencies in a mutually agreed upon time frame, then Advica would
   reserve right to terminate the agreement.

XCARE OBLIGATIONS:

- -  XCARE would be responsible for all scripts required for nodal system
   operations, including backups, system startup/shutdown and required batch
   processes.

- -  XCARE would be responsible for monitoring file growth on a frequent enough
   time interval to ensure that Advica no longer receives table space full
   messages.

- -  XCARE will be responsible all maintenance required by DB2 and AIX to run
   efficiently.

- -  XCARE will he responsible For helping to resolve ODBC errors that are caused
   by the host.

- -  XCARE will provide a list of resources currently in their employ capable of
   performing this type of work.

- -  XCARE will take whatever remedial actions necessary to prevent a crash which
   appears to be imminent

- -  XCARE will work with ADVICA to finalize a workplan by April 15, 1990
   outlining the actions required to restore the system to an acceptable state
   of performance. Remedial actions will continue as required while the workplan
   is being created.

ADVICA HEALTH RESOURCES, INC.

* Confidential Treatment Requested
<PAGE>   4

- -  XCARE will assist Advica in system related tasks such as setting up printer
   queues.

- -  XCARE will work with Advica in installing any operating system upgrades or
   patches as needed. It is understood that this type of work would require
   local resource availability from Advica.

ADVICA OBLIGATIONS:

- -  Advica will perform the daily mounting and unmounting of backup media.

- -  Advica will have available as needed personnel to operate the system console
   to handle such operations as hardware troubleshooting and network security,
   administration.

- -  Advica will upgrade hardware, if necessary to adequately support system
   growth requirements.

- -  Advica will maintain a service contract for both hardware and operating
   system support.

- -  Advica will contact XCARE before performing any Systems Administration
   functions (i.e. adding table space. deleting logs, etc.), except for
   standard operations such as backups.

- -  Advica will provide XCARE with a schedule of planned system shutdown and
   startup times associated with the normally weekly backup which is normally
   performed on Sunday's.

- -  Advica will with reasonable prior notice make all reasonable efforts to make
   the system available to XCARE on Saturday afternoons for the purpose of file
   maintenance.

PERFORMANCE STANDARDS:

- -  XCARE will provide a contact (could be a pager) that is available 24 x 7.

- -  XCARE will respond to help desk issues associated with systems management
   within I hour during normal working hours (gain - 7pm, Monday - Friday,
   EST/EDT and 8am-1 pm. Saturday, EST/EDT).

REPORTING REQUIREMENTS:

- -  XCARE on an weekly basis will provide Advica with a summary report of the
   services they have performed. Advica is not looking for a detailed breakdown
   with times associated for the tasks. bur rather an overview of the tasks that
   were performed. For example, A review of tablespace was done on Monday. Five
   rabies were above x% and needed to have space added. The five tables were
   updated on Wednesday. A review of the Log Files on Friday showed nothing out
   of the ordinary, etc.

- -  XCARE will on a monthly basis will provide Advica with a report detailing
   disk space used during the prior month and a forecast of when additional disk
   space will likely be needed. Furthermore, this monthly report should detail
   any concerns XCARE may have about system performance that may necessitate
   system enhancements.

DATABASE SETUP:

- -  Ideally, Advica would like to have included as pan of this agreement that any
   future databases that need to be added would be covered as part of the
   Maintenance Services. What would be included in this is the allocation of the
   database environment and copying standard code files as needed. If this is
   not acceptable an alternative would be for both parties to agree upon a fixed
   price for these services as opposed to the current time and materials
   arrangement.

If you concur with the statements above and XCARE can provide a list of
resources available to supply this support then Advica is prepared to move
forward with this agreement immediately.

<PAGE>   5

Advica's primary point of' contact for system related issues will be our new
Systems and Operations Manager, Chris Doff. There are also other resources
available in IS Operations to act as backup for Chris.

If you have any questions or need additional information please let me know. I
can be reached at 516-233 4611.

Your cooperation in this matter has been greatly appreciated.


Sincerely yours,

1.       PRICE. The fees for the services of MPOWER pursuant to this Agreement
         are identified on Exhibit A. These fees cover those services provided
         by MPOWER pursuant to this Agreement and are based on the key
         assumptions identified on Exhibit A, as well as the cost of toll-free
         telephone lines and supplies. In the event of the addition of new
         Contracted Health Plans, the encounter pricing set forth on Exhibit A
         shall remain applicable to services provided in connection with such
         new Contracted Health Plans, except that if the requirements for such
         services are materially greater or less than the assumptions set forth
         on Exhibit A, the per encounter charge may be changed accordingly upon
         mutual agreement of the parties. Notwithstanding the foregoing, the
         parties acknowledge that the price set forth in Exhibit A is not
         contingent upon the continuation of any specific Health Plan Agreement
         between Customer and a Contracted Health Plan.

2.       PAYMENT. On or before the fifteenth (15th) day of each month, MPOWER
         shall provide Customer with a report of the aggregate number of

         or before the last day of the month during which such report was
         received by Customer. Customer's obligation to pay MPOWER hereunder

         per month, or the highest amount allowed by law, whichever is less, on
         any and all late payments (except to the extent that such amounts are
         reasonably disputed by Customer), and Customer agrees to pay such
         charges.. All prices mentioned in this Agreement are in U.S. Dollars.
         The parties agree that the prices set out in this Agreement do not
         include any sales, use or gross receipts taxes, any duties, any similar
         assessments, or any other tax imposed on any party by virtue of this
         Agreement, all of which, excluding only taxes based on MPOWER's income,
         shall be the sole liability of, and shall be paid solely by, Customer.


                               IV. INDEMNIFICATION


1.       Customer agrees to defend, indemnify, and hold harmless MPOWER, and its
         parent and subsidiaries, and their officers, directors, agents, and
         employees, from and against any claim, expenses (including reasonable
         attorney fees and litigation costs), losses, lawsuits, damages, fines,
         penalties, or other liability to any third party, including
         participating providers, nonparticipating providers, and Customer's
         insureds, arising out of or related to any negligent, wrongful, or



                                      - 8-

<PAGE>   9

         unauthorized act or omission of Customer or act or omission of MPOWER

         unauthorized.

         Contracted Health Plans, their respective parents, subsidiaries and
         affiliates, and their officers, directors, agents, and employees, from
         and against any claim, expenses (including reasonable attorney fees and
         litigation costs), losses, lawsuits, damages, fines, penalties, or
         other liability to any third party, arising out of or related to any
         negligent, wrongful, or unauthorized act or omission of MPOWER.

         lawsuit, insurance department complaint, or demand by an attorney,
         which may affect the other; provided, however, that the failure to give
         such notice will not relieve any such other party from liability under
         this Article IV with respect to such lawsuit, insurance department
         complaint or attorney demand, except to the extent that such other
         party has been actually prejudiced as a result of such failure.
         Customer shall be fully responsible for defending lawsuits based solely
         on claims arising under the provisions of its policies. MPOWER shall be
         fully responsible for defending lawsuits based solely on allegations of
         MPOWER's own misconduct. If either party is named as a defendant in a
         lawsuit for any matter for which the other party is responsible under
         this provision, the other party shall be responsible for defending such
         matter. Responsibilities under this provision includes liability for
         judgments, reasonable attorney fees, costs, penalties, and fines.

4.       Notwithstanding other provisions of this Article IV, the duty of either
         party to notify the other, defend, indemnify, or hold harmless under
         this Article shall not arise unless and until such claim, expense,
         loss, damage, fine, penalty, or other liability to any third party
         shall exceed $25,000.


                              V. DISPUTE RESOLUTION

         within forty-eight (48) hours of receipt of any complaint received from
         a Member, a Member's representative, a Contracted Health Plan (if such
         complaint involves administrative services rendered by MPOWER pursuant
         to this Agreement) or a provider of medical transportation services in
         connection with services rendered by MPOWER hereunder. MPOWER agrees to
         cooperate fully with Customer and with the applicable Contracted Health
         Plan in resolving any Member or provider complaint regarding services
         provided by MPOWER in connection with this Agreement, in accordance
         with the dispute resolution procedure set forth in the applicable
         Membership Agreement, Administrative Manual or provider agreements, as
         appropriate. In addition, MPOWER agrees to be joined in any dispute

         cooperate fully in the resolution of such dispute in accordance with
         the dispute resolution procedure set forth in the applicable Health
         Plan Agreement.

                                       -9-

<PAGE>   10

         complaint, the parties shall make every effort to amicably resolve the
         dispute pursuant to this Section V.2. The following procedures shall be
         adhered to in order to expeditiously resolve any disputes arising
         during the term of this Agreement.

         A.       The party invoking the procedures of this Section V.2 shall
                  provide written notice to the other party. Each party shall
                  designate an individual empowered to bind the organization to
                  a negotiated resolution of the dispute. Unless the dispute is
                  resolved with fewer meetings, these parties shall meet and
                  confer at least two (2) times within forty-five (45) days to
                  attempt to reach such resolution. If the matter has not been
                  resolved informally within such forty-five (45) days (which
                  period may be extended by mutual agreement), the dispute shall
                  be settled by binding arbitration, in accordance with the
                  provisions of Sections B through G of this Section V.2.

         B.       Either party may commence arbitration by sending a written
                  demand for arbitration to the other party, setting forth the
                  nature of the controversy, the dollar amount involved, if any,
                  and the remedies sought, and attaching a copy of this Article
                  V to the demand. The parties shall attempt to agree upon
                  either one or three (3) arbitrators, as they jointly deem
                  appropriate. If the parties fail to agree upon the appropriate
                  number of arbitrators and the identity of the arbitrator(s)
                  within ten (10) days after the demand for arbitration is
                  mailed, then the parties stipulate to arbitration before three
                  (3) neutral arbitrators sitting on the JAMS/Endispute ("JAMS")
                  panel administered by the Denver, Colorado, JAMS office. Each
                  party shall select one such arbitrator from the panel, and the
                  third arbitrator shall be selected by the first two so
                  selected. All three arbitrators shall be neutrals, and no
                  arbitrator shall have a conflict of interest unless waived by
                  both parties.

         C.       The parties shall share all costs of arbitration.

         D.       The arbitrator(s) shall apply the substantive law of Colorado.
                  The parties shall have the rights of discovery as provided for
                  any judicial proceeding. The Colorado evidence code shall
                  apply to testimony and documents submitted to the
                  arbitrator(s).

         E.       Arbitration shall take place in Denver, Colorado unless the
                  parties otherwise agree. As soon as reasonably practicable,
                  the arbitrator(s) shall conduct a hearing on the dispute or
                  matter to be resolved. As soon as reasonably practicable
                  thereafter, the arbitrator(s) shall arrive at a final
                  decision, which shall be reduced to writing, signed by the
                  arbitrator(s) and mailed to each of the parties and their
                  legal counsel.

         F.       All decisions of the arbitrator(s) shall be final, binding and
                  conclusive on the parties and shall constitute the only method
                  of resolving disputes or matters subject to arbitration under
                  this Agreement. The arbitrator(s) or a court of appropriate
                  jurisdiction may issue a writ of execution to enforce the
                  arbitrator's judgment. Judgment may be entered upon such a
                  decision in accordance with applicable law in any court having
                  jurisdiction.

         G.       Notwithstanding the foregoing, because time is of the essence
                  of this Agreement, the parties specifically reserve the right
                  to seek a judicial temporary restraining order, preliminary
                  injunction, or other similar short term equitable relief, and
                  grant the





                                      -10-

<PAGE>   11

                  arbitrator(s) the right to make a final determination of the
                  parties' rights, including whether to make permanent or
                  dissolve such court order.


                           VI. TERM AND TERMINATION

1.       TERM. The initial term of this Agreement shall commence on the
         Effective Date hereof and shall continue for a period of [*] ([*])

         one (1) year periods.

2.       DELAYS IN IMPLEMENTATION. In the event this Agreement is not
         implemented in accordance with the implementation schedule set forth on
         Exhibit A as to any service area noted in such schedule, and such delay
         is caused by the acts or omissions of MPOWER (except as such acts or
         omissions were directed by Customer), MPOWER shall be liable for any
         damages incurred by Customer as a result of such delay, including such
         damages payable by Customer to a Contracted Health Plan under the
         applicable Health Plan Agreement in connection with such delay in
         implementation. MPOWER shall continue implementation of the remaining
         service areas in accordance with the implementation schedule. If the
         delayed service area is not implemented within ninety (90) days of the
         scheduled implementation date, such delay by MPOWER shall be deemed to
         be a material breach of this Agreement. This section shall not apply to
         any delays in implementation resulting from the actions of Customer or
         the applicable Contracted Health Plan.

3.       TERMINATION WITHOUT CAUSE. This Agreement may be terminated without
         cause by either party by providing one hundred twenty (120) days prior
         written notice to the other party; provided, however, that if MPOWER
         terminates this Agreement pursuant to this Section, Customer shall have
         the right to exercise the option set forth on Attachment A-2 of Exhibit
         A of this Agreement, regardless of when during the term of this
         Agreement such termination occurs.

4.       TERMINATION FOR CAUSE. This Agreement may be terminated immediately
         upon written notice thereof given by either party if any one oft he
         following occurs, but in no event shall such termination relieve either
         party from any of its obligations incurred at the time of termination
         under this Agreement.

         A.       Except as provided in Section 4.B below, either party may
                  terminate this Agreement upon failure of the other party to
                  cure non-compliance with any material provision of this
                  Agreement within thirty (30) days after the terminating party
                  gives written notice of such non-compliance to the other
                  party, unless cure of the non-compliance cannot be reasonably
                  completed within thirty (30) days, in which case such cure
                  shall be commenced within such thirty (30) day period and
                  diligently pursued to completion, which completion shall occur
                  no later than forty-five (45) days after the initial notice of
                  termination. Any such termination shall be effective as of the
                  date of expiration of the applicable cure period.

         B.       In the event of breach by MPOWER, Customer may terminate this
                  Agreement in whole or in part (i.e., only as to specific
                  service areas or Contracted Health Plans).

                  comes into possession or control, even temporarily, of any

         records, including the callers' telephone numbers, to Customer as
         requested. MPOWER will provide other reasonable support to Customer's
         customer satisfaction survey activities as requested.

         insurance, including errors and omissions coverage, in a form and with

PRICING MODEL

The pricing model is broken down into two components.

         1.       Fixed infrastructure.

         2.       Monthly encounter processing.

FIXED INFRASTRUCTURE
The benefit of the MPOWER outsourcing project is the ability of Customer to
bring a fully implemented turnkey system operation in-house at the end of the
processing contract. As such, MPOWER has broken out fixed fee infrastructure
costs as follows:

         o        Operations Hardware/Software

         o        MPOWER System Software

         o        Implementation Services

A description of the hardware and software system is more specifically described
in Attachment A-1, attached to this Exhibit A and made a part of this Agreement.

The cost for these fixed infrastructure fees is $[*]. Software for on-site
Customer workstations will be approximately an additional cost of
$[*]/workstation. Customer shall pay MPOWER [*] Dollars ($[*]) upon execution of
this Agreement, [*] percent ([*]%) of the remaining balance within forty-five
(45) days after execution of this Agreement, and the remaining [*] percent
([*]%) of the balance plus additional costs for workstations upon completion of
initial implementation. If this Agreement is terminated by Customer for cause
prior to completion of implementation, MPOWER shall refund to Customer the
greater of: (a) any amounts not spent by MPOWER on its actual costs of
implementation or (b) [*] percent ([*]%) of the fee paid to MPOWER up until the
effective date of termination.

7. CUSTOMER RESPONSIBILITIES

Sections 7.1 and 7.2 of the Agreement dated January 1, 1997, are replaced with
sections 7.1, 7.2 and 7.3 below:

        7.1 Customer Responsibilities. Customer acknowledges that the MPOWER
Software reflects certain interdependent relationships, such as exist among the
data variables, logic rules and system functions of the MPOWER Software.
Customer further acknowledges that it is required and has a responsibility to
understand such data variables, logic rules and system functions, and their
interdependent relationships, and to define for its own purposes such data
variables, logic rules and system functions to the MPOWER Software in such a way
that the MPOWER Software will provide the functionality desired by Customer.
Customer acknowledges that it has or will hire and will maintain on its staff
personnel who are able to understand and define such data variables, logic
rules, system functions and interdependent relationships. Customer further
acknowledges that, even though MPOWER may assist Customer personnel in
performing these tasks, the responsibility for the effective definition and
maintenance of these data variables, logic rules and system functions resides
with Customer and not with MPOWER, unless Customer specifically requests MPOWER
to perform these tasks at the Supplemental Services Fees. Notwithstanding the
foregoing, nothing herein shall relieve MPOWER of responsibility for the
assistance that it may provide to Customer hereunder.

        7.2 Testing. Customer acknowledges that it will undertake testing of
the MPOWER Software and of the basic functionality and interdependency of its
customer-defined data variables, logic rules and system functions as set forth
in Section 4 herein, prior to commencing use of the MPOWER Software for its
business.

printed or into which files or programs on Customer controlled computers such
files are to be downloaded and manipulated, at Customer's own initiative,
responsibility and risk. Customer hereby acknowledges responsibility for
generally controlling all aspects related to the production, distribution and
control of such outputs. Customer further acknowledges that, notwithstanding
the responsibility of MPOWER to have used due care and diligence in the design
and documentation of the System, the accuracy of Customer's database within the
MPOWER Software and the accuracy of the several outputs of the MPOWER Software,
including but not limited to, outputs that control the billing, receipt or
expenditure of moneys, will be dependent on the accuracy and use of the data
variables, logic rules, system. functions and Customer data input into the
MPOWER Software by Customer and verified by Customer. Notwithstanding the
foregoing, nothing herein shall relieve MPOWER of responsibility for the
assistance that it may provide to Customer hereunder.

seeking support for questions and problems for production activities that the
Customer's Help Desk was not able to resolve on its own (each a "Service Call").

        verification by MPOWER of the problem, either through replication or
        receipt by MPOWER of complete documentation from Customer needed to
        resolve the problem -- whichever occurs last. Customer shall maintain
        immediate resource availability during all hours that MPOWER is working
        on a Service Call.

        B. Severity Level/Priority: 2

        Definition: Production degraded -- defined as a verifiable Nonconformity
        in the Shelf Version of the MPOWER Software (or verifiable failure of
        the MPOWER System hardware, if the problem arises with respect to Remote
        Processing) that does not disrupt critical business processing, but
        causes disruption to normal work flow.

        Support: MPOWER will provide telephone support twenty-fours (24) hours

        non-critical problems. A non-critical problem is defined as a verifiable
        Nonconformity in the Shelf Version of the MPOWER Software (or verifiable

        are handled differently whether the Service Call is a non-critical
        question or a non-critical MPOWER Software or MPOWER System problem. If
        a non-critical MPOWER Software or MPOWER System problem, it will be
        entered into the MPOWER Problem Reporting and Tracking System. MPOWER
        and the Customer shall jointly prioritize these non-critical problems at
        least weekly up to one year after first production use, and at least
        monthly thereafter. After prioritization, MPOWER shall produce a
        schedule for their resolution.

Within ten (10) working days after month-end, MPOWER will provide reports and
graphs to the customer liaison (see Section 16.2) comparing Service Call
performance against standards for Severity 1, 2, and 3 Service Calls -- both
for the month and the year-to-date.

For two successive calendar quarters, beginning with the first calendar quarter
after the initial Implementation Date, the Customer shall be entitled to
unlimited Service Calls from the Customer's help desk to the Help Desk (or its
"after hours" rollover to Operations). Thereafter, Service Calls to the Help
Desk in excess of sixty (60) calls per calendar quarter shall be billed as
Supplemental Services.

                             SUPPLEMENTAL AGREEMENT

        This Supplemental Agreement ("Agreement") made and entered this 24th day
of December, 1997 by and between Brokerage Services, Inc., a New Mexico
corporation with its principal place of business located at 11200 Lomas Blvd.,
N.E., Albuquerque, New Mexico 87112 (hereinafter "BSI"), and MPOWER Solutions,
Inc., a Delaware corporation with its principal place of business located at
2305 Renard Place, S.E., Albuquerque, New Mexico 87106 (hereinafter "MPOWER").

        WHEREAS BSI and MPOWER have entered into a Processing and Services
Agreement dated January 1, 1997, as well as one or more addenda to such
agreement ("Prior Agreement"); and

        WHEREAS BSI and MPOWER wish to clarify, mend, and supplement that Prior
Agreement as provided herein;

        NOW THEREFORE it is agreed as follows:

        1. HUBLINK CONTINGENCY. MPOWER has specified HUBLINK as the electronic
data interchange software engine (EDI Engine) to be utilized in conjunction with
the MPOWER system to be utilized by BSI. Until such time as BSI has paid to
MPOWER in full its Initial License Fee for the MPOWER Software and the
sub-license fee for the HUBLINK software, then the event HUBLINK becomes subject
to any bankruptcy, insolvency, liquidation or other similar proceedings which
are not dismissed within 60 days after commencement, or withdraws support of the
EDI Engine without an entity to assume such support obligations, or should the
HUBLINK EDI Engine prove to be inappropriate or inadequate software for the
MPOWER system utilized by BSI, then in any of such events MPOWER shall either
(i) provide at its own cost a replacement EDI Engine software package acceptable
to BSI, or (ii) remove such HUBLINK software and refund all fees paid by BSI
with respect to such HUBLINK software.

        2. SOURCE CODE ESCROW. In the event that MPOWER becomes subject to any
bankruptcy, insolvency, liquidation or other similar proceedings which are not
dismissed within 60 days after commencement, or in the event that MPOWER ceases
to provide support reasonably acceptable to BSI for a current release of the
MPOWER software, or for such earlier releases for which MPOWER in the Prior
Agreement has committed to provide support to BSI, and MPOWER has not assigned
its rights and obligations to another entity reasonably acceptable to BSI which
has agreed to provide such support to BSI, then BSI shall have access to and
shall be granted without any further cost to BSI a perpetual, fully paid up,
non-exclusive license to the source code of the current release, (and the
current release used by BSI, if different) of the MPOWER Software to use the
source code and the MPOWER Software for its own use, as defined in the Prior
Agreement, and not for relicense or to create derivative works for relicense,
and BSI shall be considered to have exercised and to have satisfied its payment
obligations for the Source Code Buyout Option. BSI access shall be through
Norwest Bank New Mexico, N.A. as escrow agent. The escrow account shall be
established on or before December 29, 1997. In addition to the source code,
there shall also be escrowed all MPOWER documentation related to the software
procedures manual, system

<PAGE>   2

restoration procedure, and disaster recovery system, and in any of the events
specified above BSI shall also have access and be granted all necessary rights
to utilize such information without further cost or payment.

        3. BSI DATA ESCROW. MPOWER acknowledges that the data used on the MPOWER
System by BSI is the property of BSI. MPOWER routinely provides backup tapes of
this data and deposits such backups in backup storage. MPOWER agrees to
instruct its backup storage agent, who may change from time to time to another
agent reasonably acceptable to BSI, to release such data to BSI at any time, as
it is the property of BSI in custody with MPOWER. Should MPOWER elect to change
the data escrow company, MPOWER will promptly notify BSI as to the name and
address of the new company.

        4. ONSITE PROCESSING. Anytime after October 1, 1998, upon 90 days prior
written notice, BSI shall have the fight and option to cancel the Remote
Processing. Services being provided by MPOWER and to transfer the processing of
the MPOWER Software to BSI Premises under BSI direction (the "Onsite Processing
Option"). The license fee, maintenance charges, and other charges, to be paid by
BSI to MPOWER in such event shall be as set forth in Exhibit A hereto.
Additionally, BSI shall have the right and option to acquire the RISC/6000 Model
J50 computer utilized by MPOWER in processing BSI data at such point
(acquisition price for the RISC/6000 is set forth in Exhibit A), or
alternatively, to acquire another computer on which to run the MPOWER system on
the BSI premises.

        5. NOTICES. Notice under this Agreement shall be in writing and shall be
effective when actually delivered. If mailed, notice shall be deemed effective
48 hours after mailing as registered or certified mail, postage prepaid,
directed to the other party at the address set forth above or such other address
as the party may indicate by written notice to the other.

        6. SURVIVAL. Any of the terms and covenants contained in this Agreement
which require the performance of either party after the termination shall
survive the termination.

        7. WAIVER. Failure of either party at any time to require performance of
any provision of this Agreement shall not limit the party's right to enforce the
provision, nor shall any waiver of any breach of any provision be a waiver of
any succeeding breach of any provision or a waiver of the provision itself for
any other provision.

        8. ASSIGNMENT. Except as otherwise provided with. this Supplemental
Agreement, the assignment and transfer provisions of Section 17.6 of the Prior
Agreement shall apply as well to this Supplemental Agreement.

        9. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of New Mexico without references to
principles of conflicts of law.

        10. PREVAILING PARTY CLAUSE. In the event an arbitration, suit or action
is brought by any party under this Agreement to enforce any of its terms, or in
any appeal therefrom, it is agreed that

<PAGE>   3

the prevailing party shall be entitled to reasonable attorneys fees and costs to
be fixed by the mediator, arbitrator, and/or court.

        11. FURTHER ACTION. The parties hereto shall execute and deliver all
documents, provide all information and take or forbear from all such action as
may be necessary or appropriate to achieve the purposes of this Agreement.

        12. GOOD FAITH. The parties hereto covenant, warrant and represent to
each other good faith, complete cooperation, due diligence and honesty in fact
in the performance of all obligations of the parties pursuant to this Agreement.
All promises and covenants are mutual and dependent.

        13. SAVINGS PROVISION. If any provision of this Agreement, or the
application of such provision to any person or circumstance, shall be held
invalid, the remainder of this Agreement, or the application of such provision
to persons or circumstances other than those as to which it is held invalid,
shall not be affected thereby.

        14. DEFINITIONS INCORPORATED FROM PRIOR AGREEMENT. Any of the
capitalized terms or definitions used in this Agreement that are not
specifically defined in this Agreement shall have the meaning assigned to them
in the Prior Agreement.

        15. PAYMENTS DETAILED ON EXHIBIT A. The payment schedule in Exhibit A
hereto redistributes the Fees agreed to in the Addendum to Processing and
Services Agreement, dated July 25, 1997 (the "Addendum"), which Addendum is part
of the Prior Agreement. Such redistribution takes into account the change in
timing for the use by BSI of the MPOWER Software license on the RISC/6000
environment and the potential exercise of the Onsite Processing Option. Any
other Fees outlined in the Prior Agreement, not affected by this redistribution
remain in full force and effect. If the Onsite Processing Option is not
exercised on October 1, 1998, then the prior payment terms remain in effect. If
the Onsite Processing Option is exercised after October 1, 1998, then the One-
time Cash Payment for the RISC/6000 shall be reduced by [*] ([*]) of $[*] for
each month that such exercise is postponed.

        16. NEW MEXICO MEDIATION\ARBITRATION. If either party believes that a
controversy or claim arising out of this Agreement cannot be settled informally
by the parties, either party may invoke this Section, in which case the
controversy or claim shall be settled by mediation in Bernalillo County, New
Mexico. Within ten (10) days after written request for mediation shall be made
by a party on one side to the party on the other, the parties shall jointly
select a mediator. If the parties are unable to agree upon a mediator, then each
party shall designate a representative who shall, with the representative
designated by the other party, select a mediator. The mediator shall hear and
attempt to resolve the dispute. The hearing on the dispute shall be held no
later than thirty (30) days after the request for appointment of a mediator.
Whenever any action is required to be taken under this Agreement within a
specified period of time and the taking of such action is materially affected by
a matter submitted to mediation, such period shall automatically be extended by
ten (10) days plus the number of days that are taken for the determination of
the matter by mediation.

reimbursed at the Supplemental Service Fees rates set forth in Exhibit 2 for the
time spent in determining that such modification or enhancement was the cause of
the Nonconformity, and MPOWER agrees to provide Supplemental Services support as

               not purchasing title to the MPOWER Software or copies thereof,
               but rather is being granted a license to use the MPOWER Software
               pursuant to the terms herein. Customer shall not sell, License,
               transfer, or otherwise make available (except as expressly
               provided herein) any portion of the MPOWER Software to others,
               including but not limited to Related Parties and non-Related
               Parties for which Customer is providing processing services
               pursuant to the terms hereof, nor permit the foregoing, except

               process workflow diagrams, and any other structural templates and
               other similar information provided by, developed or reviewed by
               or in conjunction with MPOWER, or used by MPOWER in assisting
               Customer in the installation, implementation or on-going use of
               the MPOWER Product, and methodologies related thereto
               ("Proprietary Information") are the exclusive property of MPOWER
               or MPOWER's suppliers and that such Proprietary Information is
               confidential, has tangible value and includes trade secret
               information of MPOWER and/or MPOWER's suppliers. MPOWER


                                  Page 9 of 59
<PAGE>   10



               and/or MPOWER's suppliers shall retain all rights to the
               Proprietary Information, including all copyright fights therein,
               except to the extent to which MPOWER grants rights to Customer to
               use the Proprietary Information pursuant to this Agreement.
               Customer may not create Derivative Works based upon the
               Proprietary Information in whole or in part. All improvements,
               enhancements and modifications to the Proprietary Information
               shall be owned exclusively by MPOWER or MPOWER's suppliers.
               Without MPOWER's prior written consent, Customer shall nor
               decompile, disassemble or reverse engineer any Proprietary
               Information.

               (c) Notwithstanding the above, Customer and MPOWER acknowledge
               that the structural definitions of any system setups, benefit
               plans, provider contracts, fee groups, ad hoc reports, letter
               formats, sample letter content, workflow diagrams of Customer
               business processes, and any other structural templates, that have
               been provided, developed, reviewed or verified in whole or in
               part by or with the support of MPOWER, its employees or agents,
               do not constitute Proprietary Information of Customer within the
               meaning of this Section 2,6, but that the License to the MPOWER
               Software granted in Section 2.1 includes the right to use under
               license such Proprietary Information; provided, however, that
               specific provider and benefit contract rates, the names,
               demographic information, contractual relationships, and medical
               information of any group, member, provider or other entity with a
               contractual relationship with Customer shall be considered
               Proprietary Information of Customer, unless such information is
               available through public sources (that have not been released by
               or through the agency of MPOWER) or through publicly available
               filings with any insurance or health care regulatory agency or
               with any industry accreditation or reporting body.

               (d) Customer agrees to use at least commercially reasonable
               methods to secure and protect the MPOWER Software and the
               Documentation as MPOWER Confidential Information as defined
               herein, in a manner consistent with the manner in which it
               protects its own most sensitive confidential information.

               (e) MPOWER agrees to use at least commercially reasonable methods
               to secure and protect the Confidential Information of Customer as
               defined herein, in a manner consistent with the manner in which
               it protects its own most sensitive confidential information.

        2.7 Modification by Customer. In the event that Customer exercises its
option for the Source Code Buyout Option, Customer shall have the right to
modify the MPOWER


                                 Page 10 of 59
<PAGE>   11



Software for Customer Processing without notifying MPOWER and without obtaining
MPOWER's consent provided that (i.) Customer's ownership of such modifications
shall be subject to MPOWER's proprietary rights in the MPOWER Software and to
the provisions of this Section, (ii.) MPOWER's warranties and support
obligations related to the MPOWER Software shall apply only to the Shelf
Version, and (iii.) Customer shall not market or distribute such modifications
(except Customer may distribute descriptions and/or documentation of such
modifications to Related Parties and non-Related Parties) which distribution or
marketing shall be deemed a violation of MPOWER's proprietary rights in the
MPOWER Software. If Customer desires MPOWER to continue to provide support
services, Customer shall offer all modifications made by Customer to MPOWER for
inclusion in the MPOWER Software, subject to the mutual agreement by the parties
as to the consideration, if any, to be paid to Customer in return for Customer
costs and efforts in development of such modification(s). MPOWER shall have the
right to distribute such modifications as General System Enhancements, and if
MPOWER does so, such modification shall be covered by the MPOWER warranty and
support obligations as set forth in this Agreement. Subject to the foregoing,
Customer agrees that all modifications accepted by MPOWER in writing shall be
owned by MPOWER. All right, tide and interest in such accepted modifications are
hereby irrevocably assigned by Customer to MPOWER. All such modifications shall
belong exclusively to MPOWER, with MPOWER having the right to obtain and to hold
in its own name copyright registrations, patents and such other intellectual
property protection as may be appropriate to the subject matter and any
extensions and renewals thereof. Customer agrees to give MPOWER reasonable
assistance, at MPOWER's expense, required to perfect MPOWER's rights set forth
herein.

        2.8 Support for Modifications.

            (a) Modifications Not Included in the MPOWER Software; Support
Costs. In the event (i.) MPOWER modifies or enhances the MPOWER Software at
Customer's request pursuant to Section 3.2, or Customer modifies the MPOWER
Software pursuant to Section 2.7; and (ii.) such modifications or enhancements
do not have general applicability for MPOWER's customers and are not offered as
General Systems Enhancements, in order to provide support for such modifications
and enhancements, MPOWER will need to agree, in writing, to provide support for
such modifications and enhancements, and Customer agrees that there may need to
be an increase in the MF and/or the Fees for Maintenance Support Services. In
the event that MPOWER agrees, in writing, to provide such support, and
reasonably believes that an increase in the MF or the Fees for Maintenance
Support Services is required due to Customer Specific modifications, the parties
shall meet and discuss the nature of the increase. In the event that MPOWER does
not agree to provide such support, or if the parties fall to agree upon the
amount of the increase to the MF or the Fees for Maintenance Support Services,
MPOWER shall have no obligation to support such modifications and enhancements.

            (b) Modifications Included in the MPOWER Software. Modifications
made to the MPOWER Software either by Customer, pursuant to Section 2.7, or by


                                 Page 11 of 59
<PAGE>   12



MPOWER, pursuant to Section 3.2, which are included in the MPOWER Software as
General System Enhancements by MPOWER shall be supported by MPOWER as set forth
in Section 2.4.

        2.9 Core Services. In consideration of the payment of the License Fees
by Customer, M. POWER shall, during the term of this Agreement, provide the Core
Services set forth in Exhibit 1, except as otherwise provided in Exhibit 2.

3. SUPPLEMENTAL SERVICES

        3.1 Supplemental Services. Supplemental Services may include as
applicable (i.) conversion services to convert Customer data; (ii.) system setup
such as the establishment of benefit plans, pricing information, tracking
information, capitation rules, procedure and diagnosis code files and fund
accounting and billing rules; (iii.) services for modifying the MPOWER Software
for enhancements and modifications; (iv.) training support after initial
training; (v.) consulting services; and (vi.) project coordination and
management for the above Supplemental Services. All such Supplemental Services
shall be described in an applicable Work Order and shall be undertaken by MPOWER
only pursuant to a Work Order. For services requested by Customer which are
beyond the scope of the services generally contemplated hereunder, for special
circumstances, or if the geographic location in which any MPOWER services are to
be provided for Customer demands higher labor or resource costs, MPOWER will
provide Customer with written notice, and MPOWER reserves the right to propose a
new fee structure or different rates, which fee structure or rates will be
detailed in the appropriate Work Order.

        3.2 Enhancements and Modifications Under Work Orders. Pursuant to this
Section 3.2 and the applicable Work Order, Customer may identify enhancements or
modifications which it desires to have MPOWER make to the MPOWER Software, such
as integration to other software systems, modifications for legal requirements,
and other functional enhancements. Customer shall be responsible for providing
to MPOWER a description of the changes which Customer requests to be made in the
MPOWER Software. MPOWER shall have the right to design any Customer requested
enhancements or modifications in a way which, in MPOWER's reasonable opinion,
will not adversely affect the MPOWER Services or the structure or performance of
the MPOWER Software or will have general applicability. In the event MPOWER
agrees to provide such enhancements or modifications to the MPOWER Software,
such enhancements or modifications shall be owned by MPOWER and licensed to
Customer as part of the MPOWER Software subject to Section 2. Resources utilized
by MPOWER in providing services pursuant to any such requests will be detailed
in applicable Work Orders.

        3.3 Data Integrity. Customer acknowledges that, although MPOWER may, as
part of Supplemental Services, perform certain conversion tasks (for which
MPOWER shall be responsible), including development of files and programs for
the conversion of Customer data into formats for the MPOWER Software, the
quality and integrity of all Customer data


                                 Page 12 of 59
<PAGE>   13



provided to MPOWER, and the results obtained or resulting from poor or
inaccurate data are solely Customer's responsibility.

        3.4 Access. In order for the Supplemental Services to be completed in a
timely and successful manner, Customer shall provide MPOWER with such access to
applicable information and key Customer personnel as MPOWER may reasonably
request from time to time during the period the Supplemental Services are being
performed. In connection with the Supplemental Services, MPOWER will be entitled
to submit various materials, including time schedules, business requirements,
specifications, and test results, for Customer's review, comment, sign-off, or
approval. Customer will respond to each such request as soon as reasonably
practicable, and, in any event, in a time frame consistent with the applicable
project plan, and shall not unreasonably withhold any sign-off or approval
requested by MPOWER.

4. ACCEPTANCE

        For all deliverables, including the MPOWER Software and General System
Enhancements and Customer-specific enhancements and modifications provided
pursuant to an applicable Work Order, whether for MPOWER Processing or for
Customer Processing, Customer shall, within thirty (30) days of receipt of the
deliverable, or within such other time period as may be agreed to in writing by
the parties, review and, if applicable, test the deliverable and approve it or
notify MPOWER in writing of non-approval, documenting in reasonable detail any
and all material defects in the deliverable which prevent it from conforming to
the Documentation or specifications therefor, as applicable. Work Orders for
Customer enhancement requests will include specification of an acceptance text
period that is mutually agreed to by Customer and MPOWER and which shall be
reflective of the estimated size and complexity of the deliverable specified by
the Work Order. MPOWER shall, upon receipt of such notice, use its best efforts
to correct any such material failures and shall notify Customer of its
completion thereof. Customer shall, after receipt of said notice, review the
deliverable and report. Customer shall do so promptly using diligent efforts,
but in no event shall such process exceed fifteen (15) days. The above cycle
shall be repeated as is necessary. A deliverable shall be deemed accepted by
Customer if either:

            (a) Customer notifies MPOWER in writing of its acceptance and the
acceptance date shall then be the date of such notice;

            (b) Customer fails to notify MPOWER in writing within the applicable
time period of any material defect in the deliverable and the acceptance date
shall then be the last day of said period; or

            (c) Customer places in productive use any portion of the deliverable
and the acceptance date shall then be the thirtieth day of such productive use.
Productive use for purposes of the foregoing shall not include the use by
Customer of the MPOWER Software in a parallel processing environment where
Customer is utilizing the MPOWER Software to


                                 Page 13 of 59
<PAGE>   14



process a limited number of Members during a reasonable period of time for the
purpose of testing the MPOWER Software. Furthermore, notwithstanding the above,
the acceptance date shall not be considered completed as long as any online
production processing is still being conducted by Customer on the MPOWER
mainframe because of MPOWER's inability to transfer all of Customer's business
processing from the mainframe platform to Customer's client-server platform.

        Customer agrees that it will so test any modifications or enhancements
made by MPOWER for Customer under an applicable Work Order and made part of a
Release and all General System Enhancements. The version and release of the
MPOWER Software so accepted by Customer shall be deemed the current Shelf
Version. Customer and MPOWER shall maintain copies of each Shelf Version. The
obligation of MPOWER to maintain any enhancements or modifications made
specifically for Customer that are nor part of either General System
Enhancements or a Release shall be specified in the Work Order that authorizes
such enhancements or modifications or in a subsequent Work Order.

5. FEES AND CHARES

        5.1 Fees and Charges. The Fees for the MPOWER License and Services are
described in Exhibit 2 attached hereto.

        5.2 Timeliness of Payment. All Fees payable by Customer hereunder shall
be paid by Customer on a monthly basis. Any applicable Remote Processing Fees
shall be due and payable in advance at the beginning of each month. Any other
sum due MPOWER hereunder for which a time for payment is not otherwise specified
will be due and payable within twenty (20) days after the date of Customer's
receipt of an invoice therefor from MPOWER. If Customer fails to pay any amount
due within thirty (30) days from the due date, late charges of 1 1/2% per month
shall also become payable by Customer to MPOWER. In addition, failure of
Customer to fully pay any amount due within sixty (60) days after the due date
shall be deemed a material breach of this Agreement and shall be sufficient
cause for immediate termination hereof. If Customer fails to pay, when due, any
amount payable hereunder or fails to fully perform its obligations hereunder,
Customer agrees to pay, in addition to any amount past due, plus interest
accrued thereon, all reasonable expenses incurred by MPOWER in enforcing this
Agreement including but not limited to all expenses of any legal proceeding
related thereto and all reasonable attorneys' fees incurred in connection
therewith. No failure by MPOWER to request any such payment or to demand any
such performance shall be deemed a waiver by MPOWER of Customer's obligations
hereunder or a waiver of MPOWER's right to terminate this Agreement.

        5.3 Fee Changes. Not Applicable.

        5.4 Taxes. There will be added to any charges under this Agreement, and


                                 Page 14 of 59
<PAGE>   15



Customer will pay to MPOWER, amounts equal to any taxes, however designated or
levied, based upon such charges, or upon this Agreement or the services or
materials provided hereunder, or Customer's use thereof, including state and
local sales, use, privilege or excise taxes based on gross revenue, and any
taxes or amounts in lien thereof paid or payable by MPOWER in respect of the
foregoing, but excluding any franchise taxes, taxes based on the adjusted gross
income of MPOWER, and employee withholding, FICA., and other taxes relating to
MPOWER personnel performing services hereunder.

6. PROBLEM RESOLUTION

        Subject to the limitations in support for prior Releases provided by
MPOWER as set forth in Section 3 hereof, in the event MPOWER receives notice
from Customer of a Critical Failure in the most current Release of the MPOWER
Software or in the one prior Release immediately preceding the most current
Release of the MPOWER Software, pursuant the notice provisions of Section 16.4,
MPOWER agrees to respond to such notice by assigning a qualified individual to
attempt to remedy the Critical Failure, and agrees to use commercially
reasonable efforts to remedy the Critical Failure in accordance with the
provisions of Section 8.2 herein commensurate with the severity of the problem
and the timeliness and quality of information regarding the problem received
from Customer in accordance with the Definition, Support and Time Frame for
Resolution paragraphs of the Help Desk section of Exhibit 1.

7. CUSTOMER RESPONSIBILITIES

        7.1 Customer Responsibilities. Customer acknowledges that MPOWER
Software reflects certain interdependent relationships, such as exist among the
data variables, logic rules and system functions of the MPOWER Software.
Customer further acknowledges that it is required and has a responsibility to
understand such data variables, logic rules and system functions, and their
interdependent relationships, and to define for its own purposes such data
variables, logic rules and system functions to the MPOWER Software in such a way
that the MPOWER Software will provide the functionality desired by Customer.
Customer acknowledges that it has or will hire and will maintain on its staff
personnel who are able to understand and define such data variables, logic
rules, system functions and interdependent relationships. Customer further
acknowledges that, even though MPOWER may assist Customer personnel in
performing these tasks, the responsibility for the effective definition and
maintenance of these data variables, logic rules and system functions resides
with Customer and not with MPOWER, unless Customer specifically requests MPOWER
to perform these tasks at the Supplemental Services Fees. Notwithstanding the
foregoing, nothing herein shall relieve MPOWER of responsibility for the
assistance that it may provide to Customer hereunder.

        7.2 Testing. Customer acknowledges that it will undertake testing of the
MPOWER Software and of the basic functionality and interdependency of its
customer-


                                 Page 15 of 59
<PAGE>   16



defined data variables, logic rules and system functions as set forth in Section
4 herein, prior :o commencing use of the MPOWER Software for its business.

        7.3 Customer Data. Except as may be provided under an applicable Work
Order, Customer shall be responsible for inputting and ensuring the accuracy,
validity and completeness of all data variables, logic rules, system functions
and Customer data, including but not limited to group, subscriber, Member,
provider, utilization, encounter, claims, capitation, fund accounting, billing,
collection, broker, benefits, product contract, provider contract, provider
fees, standard business measures, and other similar or related data. Customer
shall also be responsible for inputting and ensuring the accuracy, validity and
completeness of all user-defined report definitions, all report and batch
production job specifications and priority scheduling criteria. Customer shall
also be responsible for initiating, monitoring, operating, printing and ensuring
the accuracy, validity, and completeness of all print outputs and file
downloads, including but not limited to all reports, premium bills, checks,
etc., determining how many and on what print stock such outputs are to be
printed or into which files or programs on Customer controlled computers such
files are to be downloaded and manipulated, at Customer's own initiative,
responsibility and risk. Customer hereby acknowledges responsibility for
generally controlling all aspects related to the production, distribution and
control of such outputs. Customer further acknowledges that, notwithstanding the
responsibility of MPOWER to have used due care and diligence in the design and
documentation of the System, the accuracy of Customer's database within the
MPOWER. Software and the accuracy of the several outputs of the MPOWER Software,
including but not limited to, outputs that control the billing, receipt or
expenditure of moneys, will be dependent on the accuracy and use of the data
variables, logic rules, system functions and Customer data input into the MPOWER
Software by Customer and verified by Customer. Notwithstanding the foregoing,
nothing herein shall relieve/MPOWER of responsibility for the assistance that it
may provide to Customer hereunder.

        7.4 Other Customer Obligations. In addition to its obligations
hereunder, Customer will on a timely basis:

               (a) Establish appropriate priorities for Customer, on a regular
               basis and no less frequently than every three months, that relate
               to MPOWER Services and communicate the same to MPOWER. Customer
               recognizes that changes in such priorities may result in
               additional fees hereunder for additional staff, as Incremental
               Support, or reordering of other priorities to provide MPOWER
               Services within the current Fee structure;

               (b) Cooperate with MPOWER by, among other things, making
               available, as reasonably requested by MPOWER, management
               decisions, information, approvals, and acceptances in order that
               MPOWER may properly accomplish its obligations and
               responsibilities hereunder;


                                 Page 16 of 59
<PAGE>   17



               (c) Carefully inspect and review all MPOWER generated reports and
               other output and notify MPOWER of any incorrect reports or
               output;

               (d) Personalize, maintain, reproduce and distribute (solely for
               Customer's internal use) procedure manuals and documentation used
               by Customer personnel in connection with the MPOWER Services and
               Software;

               (e) Train applicable Customer personnel in the proper use of
               MPOWER Software;

               (f) Pay all costs of acquisition, installation, use and
               maintenance of equipment at Customer's site, as required for the
               performance of MPOWER Software and Services;

               (g) Properly maintain the Customer equipment at all Customer
               sites;

               (h) Properly maintain the operating environment, operating
               system, network and database software as agreed to between the
               parties;

               (i) Such other responsibilities as set forth herein.

Customer agrees that to the extent its failure to meet its obligations set forth
in this Section affects the ability of MPOWER to perform MPOWER's obligations
under this Agreement, MPOWER shall be relieved of such obligations.

8. WARRANTIES

        8.1 MPOWER warrants that it either owns the rights to the MPOWER
Software or has the right to grant the license to Customer herein, and that it
either owns or has licensed in the manner contemplated by this Agreement any
other software used in the provision of the MPOWER Services to Customer,
including but not limited to the enhancements or modifications provided by
MPOWER pursuant to an applicable Work Order. MPOWER warrants that the MPOWER.

                                 Page 17 of 59
<PAGE>   18



notice of the same and Customer fully cooperates, at MPOWER's expense, in the
defense of any such claim. Following such notice of a claim or of a threatened
or actual suit, MPOWER shall, upon written notice to Customer and at MPOWER's
expense, either: (a) procure for Customer the right to continue using such
MPOWER Software; (b) replace or modify same so that it becomes non-infringing;

               The cap shall apply only to MPOWER services related directly to
               conversion services and shall nor include services and products
               of third party contractors for third party products, nor shall it
               include services of MPOWER related to such third party products
               or contractors. The conversion period will end when Customer
               commences Customer Processing for any of its customers.

        C.     During conversion MPOWER shall charge Customer for third party
               services as a direct pass through.

        D.     After conversion, the rates for outside independent contractors
               provided by MPOWER for Supplemental Services shall be the greater
               of (i.) the rates set forth above (for applicable skill sets) or

V.      REMOTE PROCESSING FEES

        Remote Processing Fees shall continue under the Prior Agreement until
        Customer commences a live production environment under this Agreement.
        It is not anticipated that there will be Remote Processing Fees under
        this Agreement, as that term is used in the Prior Agreement. There may
        be computer operations services under this Agreement and, if so, they
        will be covered under an applicable Work Order.

VI.     OTHER FEES.

        Other fees may pertain to the use by Customer of the MPOWER System for
        set-up, testing, training, acceptance testing or other uses not related
        to the production use of the MPOWER System for processing active Members
        of Customer or of a Related Party. Such other fees will be indicated in
        a Work Order and may include fees for third party consultants and
        vendors.

VII.    PAYMENT BY MPOWER TO EMI FOR CONVERSION OF EMI CUSTOMER
        TO MPOWER LICENSE

        Each Party acknowledges that from time to time a customer of EMI may
        elect to acquire a license to use the MPOWER Software on its own, and
        not through EMI. In those cases, where a customer of EMI elects to
        acquire a license from MPOWER and uses the data and data setups from
        EMI, MPOWER will pay to EMI a royalty payment of $[*], over the
        timeframe of the implementation of such customer and initial use by such
        customer of its own licensed software instance for the MPOWER Software,
        in consideration of the reduced implementation effort for the MPOWER
        Software because MPOWER and such customer can use the data and setups
        already accomplished by EMI. For this consideration, EMI permits MPOWER
        to use such setups and data for the respective customer. Notwithstanding
        the above, MPOWER will owe no such payment to EMI for customers that are
        jointly marketed to and signed as "joint" customers by both MPOWER and
        EMI under the MPOWER QuickStart program or a similar program. And
        further, notwithstanding anything else in this Agreement, such
        QuickStart customers will not be covered under this Agreement and will
        be assessed computer license or usage fees outside of this Agreement and
        under a separate agreement or agreements among the parties, including
        EMI and MPOWER.

                        shall promptly pay the claim. Notwithstanding the
                        foregoing, if Customer's referral authorization is
                        included in the claims submission, then the Medical
                        Necessity of the claims will be deemed to be determined,
                        and further review will not be required.

                        be paid as covered benefits in accordance with the
                        applicable network provider agreement and Membership

                        make payment on the claim within the time frame required
                        by applicable state or federal law or regulation or such
                        other period of time as set forth in the applicable
                        Administrative Manual and Membership Agreement.

                  6.    Calculate and notify provider via statement of
                        remittance for Member liability only as defined in the

                                       -6-
<PAGE>   7
damages, fines, penalties, or other liability to any third party, arising out of
or related to any negligent, wrongful, or unauthorized act or omission of

DISPUTE BETWEEN THE PARTIES. If any dispute shall arise between the parties in
connection with this Agreement that is [unrelated to a Member, provider, or
Contracted Health Plan complaint], the parties shall make every effort to
amicably resolve the dispute pursuant to this Section V.2. The following
procedures shall be adhered to in order to expeditiously resolve any disputes
arising during the term of this Agreement.

A.       The party invoking the procedures of this Section V.2 shall provide
         written notice to the other party. Each party shall designate an
         individual empowered to bind the organization to a negotiated
         resolution of the dispute. Unless the dispute is resolved with fewer
         meetings, these parties shall meet and confer at least two (2) times
         within forty-five (45) days to attempt to reach such resolution. If the
         matter has not been resolved informally within such forty-five (45)
         days (which period may be extended by mutual agreement), the dispute
         shall be settled by binding arbitration in accordance with the
         provisions of Sections B through G of this Section V.2.

B.       Either party may commence arbitration by sending a written demand for
         arbitration to the other party, setting forth the nature of the
         controversy, the dollar amount involved, if any, and the remedies
         sought, and attaching a copy of this Article V to the demand. The
         parties shall attempt to agree upon either one or three (3)
         arbitrators, as they jointly deem appropriate. If the parties fail to
         agree upon the appropriate number of arbitrators and the identity of
         the arbitrator(s) within ten (10) days after the demand for arbitration
         is mailed, then the parties stipulate to arbitration before three (3)
         neutral arbitrators sitting on the JAMS/Endispute ("JAMS") panel
         administered by the Denver, Colorado, JAMS office. Each party shall
         select one such arbitrator from the panel, and the third arbitrator
         shall be selected by the first two so selected. All three



                                      -7-
<PAGE>   8
         arbitrators shall be neutrals, and no arbitrator shall have a conflict
         of interest unless waived by both parties.

C.       The parties shall share all costs of arbitration.

D.       The arbitrator(s) shall apply the substantive law of Colorado. The
         parties shall have the rights of discovery as provided for any judicial
         proceeding. The Colorado evidence code shall apply to testimony and
         documents submitted to the arbitrator(s).

E.       Arbitration shall take place in Denver, Colorado unless the parties
         otherwise agree. As soon as reasonably practicable, the arbitrator(s)
         shall conduct a hearing on the dispute or matter to be resolved. As
         soon as reasonably practicable thereafter, the arbitrator(s) shall
         arrive at a final decision, which shall be reduced to writing, signed
         by the arbitrator(s) and mailed to each of the parties and their legal
         counsel.

F.       All decisions of the arbitrator(s) shall be final, binding and
         conclusive on the parties and shall constitute the only method of
         resolving disputes or matters subject to arbitration under this
         Agreement. The arbitrator(s) or a court of appropriate jurisdiction may
         issue a writ of execution to enforce the arbitrator's judgment.
         Judgment may be entered upon such a decision in accordance with
         applicable law in any court having jurisdiction.

G.       Notwithstanding the foregoing, because time is of the essence of this
         Agreement, the parties specifically reserve the right to seek a
         judicial temporary restraining order, preliminary injunction, or other
         similar short term equitable relief, and grant the arbitrator(s) the
         right to make a final determination of the parties' rights, including
         whether to make permanent or dissolve such court order.

                            VI. TERM AND TERMINATION

TERM. The initial term of this Agreement shall commence on the Effective Date
hereof and shall continue for a period of five (5) years unless sooner
terminated in accordance with this Article VI. Thereafter, this Agreement shall
automatically renew for consecutive one (1) year periods.

TERMINATION WITHOUT CAUSE. This Agreement may be terminated without cause by
either party by providing one hundred twenty (120) days' prior written notice to
the other party.

TERMINATION FOR CAUSE. This Agreement may be terminated immediately upon written
notice thereof given by either party if any one of the following occurs, but in
no event shall such termination relieve either party from any of its obligations
incurred at the time of termination under this Agreement.

A.       Except as provided in Section 4.B below, either party may terminate
         this Agreement upon failure of the other party to cure non-compliance
         with any material provision of this Agreement within thirty (30) days
         after the terminating party gives written notice of such non-compliance
         to the other party, unless cure of the non-compliance cannot be
         reasonably completed within thirty (30) days, in which case such cure
         shall be commenced within such thirty (30) day period and diligently
         pursued to completion, which completion shall occur no later than
         forty-five (45) days after the initial notice of termination. Any such

A.       Subject to Section II.3.A hereof, this Agreement shall automatically
         terminate if CONTRACTOR fails to apply for or maintain applicable

         provide CONTRACTOR with not less than forty-five (45) days notice of
         such termination.

D.       This Agreement may be terminated if either party becomes insolvent, or

         control, even temporarily, if any trustee in bankruptcy, or a receiver
         is appointed for it, or it makes a general assignment for the benefit
         of creditors, and no interest in this Agreement shall be deemed an
         asset of creditors.

EFFECT OF TERMINATION. Upon termination of this Agreement for any reason, the
Agreement shall be of no further force or effect, except as to the rights and
obligations of the parties arising out of transactions occurring prior to the
effective date of termination, MPOWER and CONTRACTOR shall cooperate fully with
Customer and all Contracted Health Plans to ensure a smooth transition of
administrative functions assumed by CONTRACTOR hereunder to MPOWER or directly
to another administrative services vendor. Such cooperation shall include but
not be limited to the following:

A.       CONTRACTOR shall continue to pay claims incurred during the term of
         this Agreement unless directed by MPOWER and Customer to transfer such
         functions to Customer or directly to the new administrative services
         vendor at the encounter fee contained in Exhibit A.

B.       CONTRACTOR shall transfer, as soon as possible, both electronically and
         on diskette, all data, records, and other information connected with
         claims processing and other services provided by CONTRACTOR to MPOWER
         or directly to the new administrative services vendor. Cost associated
         with this transfer will be billed by CONTRACTOR to MPOWER and paid by
         MPOWER within thirty (30) days, subject to reasonable and customary
         expenses incurred as a result of this transfer.

C.       CONTRACTOR shall provide a final accounting of claims processed within
         thirty (30) days after the end of the month in which this Agreement was
         terminated.

                             VII. GENERAL PROVISIONS

SUBCONTRACTING. All services proposed by CONTRACTOR will be performed by a
combination of its own staff and designated subcontractor(s). All subcontractors
operating on behalf of CONTRACTOR will be subject to the terms and conditions of
this Agreement. MPOWER shall have the right to approve all subcontractors prior
to their contracting with CONTRACTOR.

CUSTOMER SATISFACTION SURVEYS. Customer may periodically conduct "customer"
satisfaction surveys of policyholders, Contracted Health Plans, and providers
with whom Customer has contracted. CONTRACTOR agrees to record all interactions
with these parties and provide those records, including the callers' telephone
numbers, to Customer as requested. CONTRACTOR will provide other reasonable
support to Customer's customer satisfaction survey activities as requested.

INSURANCE. Each party (MPOWER and CONTRACTOR) shall obtain and carry general
liability insurance, including errors and omissions coverage, in a form and with
an insurer acceptable to the other, with limits of at least $1,000,000 per
occurrence and $3,000,000 in the aggregate. Within sixty (60) days of execution
of this Agreement, each party shall deliver to the other a certificate of notice
which provides that, should either party discontinue its errors and omissions
coverage, the other will be notified of the



                                       -9-

occurrence. In the event any such coverage is provided on a claims made basis,
such coverage shall be manufactured (or such party shall procure equivalent tail
coverage) for a period of five (5) years after the termination hereof.

hereunder is that of an agent, and not as partner, joint venture or employee.

<PAGE>   6

        Customer agrees not to sell, lease, assign or otherwise transfer,
        disclose or make available, in whole or in part, any portion of the
        Proprietary Information or the terms of this Agreement and Customer
        shall prevent disclosure of any part of the Proprietary Information or
        the terms of this Agreement to any third party for any reason (except
        for disclosure or access to Customer's employees, contracted entities,
        or Customer's customers which is necessary for Customer to be able to
        use the Proprietary Information in accordance with this Agreement).
        Customer agrees to notify those employees, contracted entities or
        customers to whom Customer gives access to the Proprietary Information
        of the restrictions contained in this Section II and to ensure their
        compliance with such restrictions.

        The duties and obligations which are included in this Section II shall
        survive any termination of this Agreement and/or Customer's right and
        license to use any MPOWER Product.

        If Customer desires to disclose any Proprietary Information to any third
        party or to permit any third party to have access to any Proprietary
        Information, such third parry must have a legitimate need to have access
        to such Proprietary Information (consistent with the purpose[s] for
        which such disclosure was made to Customer) and, prior to any such
        disclosure or access, Customer and such third party must enter into a
        nondisclosure agreement with MPOWER in substantially the form set out in
        the Addendum which is attached to this Master Agreement and made a part
        hereof. In no event shall Customer disclose any Proprietary Information
        to any competitor of MPOWER.

        Notwithstanding the above, Customer and MPOWER acknowledge that the
        MPOWER Product structural definitions of any system setups, benefit
        plan, provider contracts, fee groups, ad hoc. reports, letter formats,
        sample letter content, workflow diagram of Customer business processes,
        and any other structural templates, that have been provided, developed,
        reviewed or verified in whole or in part by or with the support of
        MPOWER, its employees or agents, do not constitute Proprietary
        Information of Customer within the meaning of this Section II; provided.
        however, that specific provider and benefit contract rates, the names,
        demographic information, contractual relationships, and medical
        information of any group, member, provider or other entity with a
        contractual relationship with Customer shall be considered Proprietary
        Information of Customer or of such other entity contracted with
        Customer, unless such information is available through public sources or
        through publicly available filings with any insurance or health care
        regulatory agency or with any industry accreditation or reporting body.

        Further notwithstanding the above, Customer and MPOWER acknowledge that
        Customer may create and distribute reports and data from its licensed
        use of the MPOWER Products in the normal course of its business to its
        customers, to


                                  Page 6 of 40
<PAGE>   7

        health care providers, Enrollees, employers or Plan Sponsors, government
        agencies and others with a legitimate purpose in the conduct of the
        Customer's business and the data processed by the licensed MPOWER
        Products, and that such reports and distributed dam do not constitute
        Derivative Works, unless they are used to create commercial software
        products for reuse and/or license to other parties.

III.    COPYING

        Customer, for each licensed instance of the MPOWER Product being used in
        a Live Production Environment, may make one (1) copy of each MPOWER
        Product in machine-readable form in a test region for the purpose of
        testing new releases or fixes and also one (1) copy of each MPOWER
        Product in machine-readable form for backup purposes only. Customer
        agrees that upon copying any MPOWER Product, Customer shall place a
        label on the outside of each copy medium showing the program name,
        version number and any/all copyright and proprietary notices in the same
        form as contained on the original copy.

        In addition, Customer may make automated backup copies of its production
        and testing regions for operational backup purposes without applying the
        above labels, provided that such operational backup copies are
        maintained with the acceptable industry standard security measures and
        not made available to outside parties except for the case of disaster
        recovery purposes, in which case the disaster recovery agent will be
        bound to all the confidentiality and Proprietary Information
        restrictions to which Customer is bound hereunder, and further that no
        such disaster recovery agent may be a competitor of MPOWER.

IV.     SOURCE CODE ESCROW

        At the request of Customer, MPOWER and Customer will enter into an
        agreement with MPOWER's escrow agent ("Custodian") for the depositing of
        the MPOWER Products' Source Code ("Source Code Copy"). [The current
        Custodian is NORWEST Bank.] MPOWER shall notify Customer at least ten
        (10) business days prior to a change in the entity identified as the
        Custodian. Subject to Customer's payment of all fees due under this
        Agreement in accordance with the applicable payment terms, the Source
        Code Copy so deposited will be maintained during the period Customer
        shall use and purchase, and MPOWER shall provide, software maintenance
        services for the particular MPOWER Product. The Source Code Copy will be
        updated by MPOWER upon each new Release of the particular MPOWER
        Product.

        The parties agree that the Source Code Copy shall be held by the
        Custodian for delivery to Customer under the conditions that this
        Agreement is terminated as a result of a material breach of the terms of
        this Agreement by MPOWER or MPOWER files for bankruptcy under Chapter 7,
        and its business is not continued


                                  Page 7 of 40
<PAGE>   8

        by virtue of a merger, consolidation, the sale of all or substantially
        all of its assets, or through some other transaction by another
        corporation or entity, and the Custodian of the Source Code has received
        from Customer or from MPOWER, or from a court of competent jurisdiction:
        (i) written notification of any such event or condition; (ii) demand
        that a copy of the Source Code Copy be mailed to Customer; (iii) written
        undertaking from Customer, which shall be legally binding, that the copy
        of the Source Code Copy to be supplied to Customer will be used only for
        Customer's maintenance of the MPOWER Products at a specified location
        and will be promptly returned to the Custodian at the expiration of the
        period during which Customer, under its agreement with MPOWER, has the
        right to use the MPOWER Products, and that the copy of the Source Code
        and the information and material contained therein shall be held
        confidentially by Customer, its employees and agents who are involved in
        the use and technical maintenance of the MPOWER Products, and shall not,
        under any circumstances, be disclosed or made available to any other
        person or entity; and (iv) specific instructions from Customer for the
        delivery of a copy of the Source Code Copy, with a copy of such
        instructions to MPOWER. Customer will pay the costs and expenses of the
        Custodian in carrying out the requirements of this Section.

        In addition, if Customer uses the MPOWER Product Source Code, it will
        only be for the purposes for which the Object Code is licensed under
        this Agreement and not for re-license, reverse engineering or to create
        a derivative product. The Confidential and Proprietary Information
        provisions of Section II apply also to the Source Code.

V.      TERMINATION

        Should Customer fail to pay any sum due and payable under this
        Agreement, MPOWER shall notify Customer in writing of such failure to
        pay. Customer shall then have thirty (30) days from the delivery of
        MPOWER's written notice to pay such amount(s). The foregoing sentence in
        no way relieves Customer from its obligation to pay any and all late
        chargers which may become due as set forth in Section VI below. If
        payment is not made within such thirty (30) days, MPOWER shall have the
        immediate right to discontinue any and all services under this
        Agreement. Furthermore, if payment is not made within Sixty (60) days
        from the delivery of MPOWER's written notice, MPOWER shall have the
        immediate right to terminate this Agreement.

        Should either party commit a material breach of its obligations under
        this Agreement, other than failing to pay money, the non-breaching party
        may notify the breaching parry in writing, setting out the breach, and
        the breaching party shall have sixty (60) days to remedy such breach. If
        the breaching party fails to remedy the breach during this sixty
        (60)-day period, or, with respect to those breaches which cannot
        reasonably be remedied within sixty (60) days, if the breaching party
        fails to proceed promptly after being given such notice to


                                  Page 8 of 40
<PAGE>   9

        commence remedying the breach and thereafter to proceed to remedy the
        same, the other party shall have the fight to terminate this Agreement,
        provided such party gives the breaching party thirty (30) days' prior
        written notice to that effect. Notwithstanding the foregoing, either
        party shall have the fight to immediately terminate this Agreement upon
        any breach by the other of its obligations under Section II above.

        Termination of this Agreement shall be without prejudice to all accrued
        fights and remedies either party may have and shall not affect any
        continuing rights and obligations of the parties under this Agreement.

        Upon the termination of this Agreement and/or any Attachment to this
        Agreement, Customer shall return to MPOWER all Proprietary Information
        regarding the MPOWER Product whose license is being terminated, within
        thirty (30) days after such termination and MPOWER shall return to
        Customer any proprietary information obtained in the performance of this
        Agreement within thirty (30) days after such termination.

VI.     INVOICES AND CHARGES

        Unless a specific payment date is set out in an Attachment to this
        Agreement, Customer agrees to remit all payments under this Agreement so
        that MPOWER shall receive such payments no later than thirty (30) days
        from the date of MPOWER's invoice. Customer also agrees that MPOWER
        shall have the right to charge interest charges of one and one-half
        percent (1.5%) of the outstanding balance per month, or the highest
        amount allowed by law, whichever is less, on any and all late payments,
        and Customer agrees to pay such charges. All prices mentioned in this
        Agreement are in U.S. Dollars. The parties agree that the prices set out
        in this Agreement do not include any sales, use or gross receipts taxes,
        any duties, any similar assessments, or any other tax imposed on any
        party by virtue of this Agreement, all of which, excluding only taxes
        based on MPOWER's income, shall be the sole liability of, and shall be
        paid solely by, Customer. Exhibit A to Attachment 1 of this Agreement
        provides a best efforts explanation of the currently known and
        applicable state and local taxes, duties and any similar assessments
        that are expected to apply to currently anticipated products and
        services under the Attachment 1 .to this Agreement.

VII.    FORCE MAJEURE

        Neither party shall be liable to the other for failing to fulfill any
        obligation under this Agreement if such failure is caused by an event
        which is beyond such party's reasonable control and which is not caused
        by such party's fault or negligence, including without limitation, acts
        of God, acts of war, fires, strikes, lightning, floods, epidemics, civil
        unrest, power shortages, equipment failure, delays in


                                  Page 9 of 40
<PAGE>   10

        transportation, or either party's inability to obtain necessary labor,
        material or components due to muses beyond such party's reasonable
        control.

VIII.   LIMITATION OF LIABILITY

        CUSTOMER AGREES THAT MPOWER SHALL HAVE NO LIABILITY TO CUSTOMER FOR
        INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES, EVEN IF MPOWER IS ADVISED
        OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR LOSS OF USE OR COMMERCIAL
        LOSS (INCLUDING, BUT NOT LIMITED TO, LOSS OF REVENUES AND/OR PROFITS),
        HOWEVER OCCASIONED AND WHATEVER THE FORM OF ACTION, FOR ACTUAL OR
        IMPUTED NEGLIGENCE, BREACH OF CONTRACT, BREACH OF WARRANTY OR OTHERWISE.

        FURTHERMORE, CUSTOMER AGREES THAT IN NO EVENT SHALL MPOWER BE LIABLE FOR
        DIRECT DAMAGES IN EXCESS OF:

        A. ALL LICENSE FEES CUSTOMER SHALL HAVE PAID MPOWER FOR THE PARTICULAR
           MPOWER PRODUCT WHICH IS THE SUBJECT OF CUSTOMER'S CLAIM, SHOULD
           CUSTOMER RAISE A CLAIM REGARDING SUCH MPOWER PRODUCT DURING THE
           INITIAL TWELVE (12) MONTHS OF THE SUBJECT ATTACHMENT; AND

        B. SEVENTY-FIVE PERCENT (75%) OF ALL LICENSE FEES CUSTOMER SHALL HAVE
           PAID MPOWER FOR THE PARTICULAR MPOWER PRODUCT WHICH IS THE SUBJECT
           OF CUSTOMER'S CLAIM, SHOULD CUSTOMER RAISE A CLAIM REGARDING SUCH
           MPOWER PRODUCT DURING THE SECOND TWELVE (12) MONTHS OF THE SUBJECT
           ATTACHMENT; AND

        C. FIFTY PERCENT (50%) OF ALL LICENSE FEES CUSTOMER SHALL HAVE PAID
           MPOWER FOR THE PARTICULAR MPOWER PRODUCT WHICH IS THE SUBJECT OF
           CUSTOMER'S CLAIM, SHOULD CUSTOMER RAISE A CLAIM REGARDING SUCH MPOWER
           PRODUCT SUBSEQUENT TO THE INITIAL TWENTY-FOUR (24) MONTHS OF THE
           SUBJECT ATTACHMENT.

        The parties agree that no action, regardless of form, which may arise
        out of the transactions under this Agreement may be brought by either
        party more than one (1) year after the cause of action is known, or
        ought reasonably to have been known, to the party bringing the action;
        provided, however, that this one (1)-year limitation on actions shall
        not apply to any claim of MPOWER based upon Customer's failure to pay
        any amount owed under this Agreement.

IX      INFRINGEMENT

        MPOWER agrees to defend, indemnify and hold Customer harmless against
        any, and all claims that any MPOWER Product infringes a U.S. Letter
        Patent, copyright, trade secret or the proprietary rights of others,
        provided that MPOWER shall have received timely written notice of any
        such claim and that MPOWER shall have sole control of the defense of
        such claim and all negotiations for the settlement or compromise of such
        claim.

        As of the date first written above, MPOWER warrants that it is not aware
        of any infringement, and has not been notified by any third party that
        it may be infringing, any U.S. Letter Patent, copyright, trade secret or
        the proprietary rights of others.

        If use of an MPOWER Product by Customer is enjoined, or becomes, or, in
        MPOWER's sole opinion, is likely to become, the subject of a claim of
        infringement, MPOWER will, at its option and expense, either:

        1. procure for Customer the right to continue using the MPOWER Product
           in question; or

        2. replace or modify the same so that it is functionally equivalent
           [i.e. the MPOWER Product will achieve the same or similar business
           logic result] (or contains more functionality) and non-infringing.

        Notwithstanding the foregoing, if MPOWER determines that neither of the
        alternatives set forth above is reasonably available, MPOWER will refund
        to Customer any unamortized portion of the infringing MPOWER Product's
        license fee which has then been paid by Customer. Amortization shall be
        based upon a seven (7)-year life of the infringing MPOWER Product,
        beginning on the date the infringing MPOWER Product was licensed by
        Customer from MPOWER. Should such refund occur, Customer agrees to
        return the infringing MPOWER Product to MPOWER.

        Should any refund described above occur, the license for the infringing
        MPOWER Product shall be terminated and MPOWER, its affiliates,
        subsidiaries, assigns and successor corporations shall be released from
        any and all liability arising from any and all claims, losses,
        liabilities, damages, costs or deficiencies which are then-existing or
        which may arise in the future with regard to such infringing MPOWER
        Product(s) for which MPOWER has refunded fees pursuant to this Section
        IX.


                                 Page 11 of 40
<PAGE>   12

        Notwithstanding anything contained herein to the contrary, MPOWER shall
        have no liability for any loss, cost, claim or expense caused by:

        1. alteration of any MPOWER Product provided hereunder by any party
           other than MPOWER;

        2. any loss, expense or liability resulting from any infringement which
           is a consequence of MPOWER's compliance with designs or code
           submitted to MPOWER by Customer;

        3. the use of any MPOWER Product in combination with products not
           licensed to customer by MPOWER;

        4. continuation of the allegedly infringing activity by Customer after
           Customer is notified in writing thereof and after the conclusion of a
           reasonable grace period afforded Customer in the notice to migrate
           from the infringing activity to an alternate solution; or

        5. Customer's use of an MPOWER Product other than in compliance with the
           terms and conditions of this Agreement.

        The foregoing remedy set forth in this Section IX represents the
        exclusive remedy of Customer and MPOWER's sole liability with regard to
        any claim that an MPOWER Product infringes the rights of others.

X. RESOLUTION OF DISPUTES

        If any dispute shall arise between the parties under this Agreement, the
        parties shall make every effort to amicably resolve the dispute pursuant
        to this Section X. The following procedures shall be adhered to in order
        to expeditiously resolve any disputes arising during the term of this
        Agreement.

        The party invoking the procedures of this Section X shall provide
        written notice to the other party and within five (5) business days
        following the other party's receipt of such notice, the parties'
        implementation team leaders shall attempt to resolve such dispute. If
        the parties' team leaders do not resolve such dispute within seven (7)
        business days following the date of the non-invoking party's receipt of
        notice hereunder, either party hereto shall have the right to refer such
        dispute for "Executive Review" as provided below.

        "Executive Review" shall refer to the dispute resolution process which
        shall be conducted as follows: within fifteen (15) days of any party's
        request for Executive Review, each such party shall have designated an
        executive-level employee of such party and such designated executive
        shall have met, either in


                                 Page 12 of 40
<PAGE>   13

        person or via telephone, with the other party's executive-level designee
        to attempt to resolve such dispute. If said executive-level designees
        are unable to resolve the dispute within ten (10) business days of their
        first telephone or in-person meeting pursuant to this paragraph, either
        party may request that the dispute be referred to a second level of
        Executive Review. Within ten (10) days of any party's request for such
        second level of Executive Review, the Chief Executive Officers of both
        parties hereto shall meet, in person or via telephone, to attempt to
        settle such dispute. Notwithstanding anything in this Agreement to the
        contrary, should either party feel the dispute cannot be amicably
        resolved after having negotiated in good faith to resolve such dispute
        pursuant to the foregoing provisions of this Section, such party shall
        have the right to terminate such negotiations. Nothing in this Section
        shall require either party to engage in negotiations to resolve a
        dispute for a period of more than forty-five (45) days.

        If the matter has not been resolved pursuant to the aforesaid Executive
        Review procedure within forty-five (45) days of the commencement of such
        procedure (which period may be extended by mutual agreement), the
        controversy shall be settled by arbitration in accordance with the
        American Arbitration Association. (the "Association) under the
        Commercial Arbitration Rules of the Association there in effect, by an
        arbitrator knowledgeable in the computer area. The arbitrator shall be
        selected by mutual agreement of MPOWER and Customer. If MPOWER and
        Customer can not agree upon an arbitrator, an arbitrator shall be
        appointed by the Court with jurisdiction over the dispute. The
        arbitration shall be governed by the United States Arbitration Act, 9
        U.S.C. Sec. 1-16, and judgment upon the award by the arbitrator may be
        entered by any court having jurisdiction thereof. The place of
        arbitration shall be in the jurisdiction in which the principal place of
        business of the party not filing arbitration is located (i.e.,
        Albuquerque, New Mexico for MPOWER and King County, Washington for
        Customer). Each party shall pay its own costs and expenses.

XI. SUCCESSORS AND ASSIGNS

        This Agreement shall be binding upon and shall inure to the benefit of
        the parties and their respective successors and (to the extent specified
        in any assignments) assigns. Customer shall not assign or otherwise
        transfer this Agreement without the prior written consent of MPOWER.
        Customer, however, may assign this Agreement to any subsidiary of
        Customer in which Customer owns an equity position of 51% or more, by
        giving thirty (30) days notice to MPOWER.

        period, such subcontract will contain a clause to the effect that, until
        the expiration of four (4) years after the furnishing of such services
        under such subcontract, the subcontractor shall, upon receipt of written
        request and if then required to make such information available under
        the then-existing law, make available to the Secretary, Comptroller
        General, or any of their duly authorized representatives, the
        subcontract, books, documents, and/or records of such subcontractor that

           Release of MPOWER(TM) other than the then-most-recent Release, or the
           Release prior to the then-most-current Release, provided such Release
           has been available for Customer's use for a period of six (6) months
           or longer, MPOWER reserves the right, at its sole option, to
           terminate its obligations to provide maintenance services under this

        this Section V shall automatically continue, on an annual basis, unless
        either party shall give written notice to the other that it desires not
        to renew such maintenance services. The parties agree that such written
        notice shall be remitted for receipt by the other no less than ninety
        (90) days prior to the end of the then-current annual maintenance
        period.

        MPOWER(TM) made by Customer. MPOWER agrees to add the items in this list
        to the queue of enhancements for inclusion in future Releases, which
        requested enhancements will be handled by MPOWER according to MPOWER's
        development methodology and protocols and the terms of this Agreement
        regarding future Releases. Items numbered 4 (UB-92 Requirements) and 6
        (Referral/Authorizations) are considered the highest priority by
        Customer and MPOWER states that these items have been added to the
        priority list for the next Release, which is currently scheduled for the
        end of the second quarter of 1998. Item number 7 (Original Date Stamp on

        effective date of this Agreement. All other enhancements indicated in

        -  Washington State will assess both B & O tax and sales tax on MPOWER's
           software and third party software, and the annual maintenance fees
           (since they include enhancements and upgrades of the software).

                        PROPOSAL FOR EDI INTERFACE ENGINE

        MPOWER currently provides interfaces to provider based systems through
        an interface engine ("Interface Engine"). MPOWER currently has the right
        to sublicense our integration partner HUBLink's HUBLink Integrator as
        an Interface Engine to enable connectivity and message exchange between
        applications without custom programming.

        HUBLink Integrator supports industry standards such as HL7 for ADT and
        patient/member registration, billing, scheduling and clinical decision
        support (lab, radiology and pharmacy results and orders). In addition,
        HUBLink and MPOWER have developed an industry standard X.12 EDI
        interface that provides support for HCFA 1500, UB92 and other electronic
        claim and certification processing.

        HUBLink Integrator is licensed as a component of the MPOWER system that
        enables easy participation in an enterprise-wide delivery system. In
        addition, HUBLink Integrator may be used to facilitate message brokering
        and distribution across all systems and has the scalability and
        throughput to function as the heart of a diversified message brokering
        architecture.

        MPOWER may in the future use and/or sub-license a different interface
        Engine. A preliminary estimate of the cost to Customer for an Interface
        Engine is given below. Any acquisition of an Interface Engine to be used
        with the MPOWER Product shall be governed by a separate agreement.

                   SEVERITY DEFINITIONS AND RESOLUTION PROCESS

- - SEVERITY 1.

        The problem causes complete loss of service in the production and
        staging environment and work cannot reasonably continue. The problem or
        defect has one or more of the following characteristics:

        [ ] > Data corruption. Physical or logical data is unavailable or
              incorrect.
              Examples: Block format corruption, invalid indices, corruption of
              meta-data, incorrect results.

        [ ] > Critical functionality is not available.

        [ ] > System hangs. The process hangs indefinitely or there is severe
              performance degradation, causing unreasonable waits for resources
              or response, as if the system is hanging.

        [ ] > The entire MPOWER application crashes repeatedly.

        [ ] > Database process or background processes fall and continue to
              fail after restart attempts.

        [ ] > Potential for above occurrences is defined imminent.

        RESOLUTION OF SEVERITY 1: Until the issue is resolved MPOWER Solutions
        will work on Severity 1 around the clock (7x24). As a result of the
        severity, the customer must provide MPOWER with a point of contact
        during the 7x24 period. The customer's point of contact will assist the
        MPOWER customer support and development staff in gathering data, testing
        fixes in the customer's testing region, and applying fixes to the
        customer production environment.

- - SEVERITY 2:

        Problem or product defect causes a severe impact on the customer's
        business regardless of customer environment. No workaround is available,
        however operations can continue in a restricted fashion. The problem or
        defect has one or more of the following characteristics:

        [ ] > Business Impact Examples: The customer can handle current
              volume, but will not be able to handle quarter close; At close,
              customer finds totals wrong, but close is not for a few weeks.

        [ ] > Internal software error, causing the application to fall to run
              to completion, or return wrong results, or software error
              severely degrades performance.

        [ ] > Some important functionality is unavailable, yet the system can
              continue to operate in a restricted fashion.

        [ ] > Potential for above occurrences is defined imminent.





                                 Page 35 of 40
<PAGE>   36
        RESOLUTION OF SEVERITY 2: MPOWER Solutions will work on Severity 2 bug
        based on customer assigned priority. Severity 2 fixes will be added in
        the next scheduled maintenance or patch release.

- - SEVERITY 3.

        Problem or product defect causes minimal impact on the Customer's
        business. The impact of the problem or defect is minor or an
        inconvenience, such as a manual bypass to restore product functionality.
        The problem or defect has one or more of the following characteristics:

        [ ] > A software error for which there is an acceptable workaround.

        [ ] > Software error minimally degrades performance.

        [ ] > Software error or incorrect behavior has minor impact the
              operation of the system.

        RESOLUTION OF SEVERITY 3: Fixes for severity 3 bugs will be added to the
        priority list for the next major scheduled release of the product. The
        order of priority for resolving severity 3 issues will be assigned
        jointly by the Customer and MPOWER.

- - SEVERITY 4.

        The problem or product defect causes NO impact on the Customer's
        business. The problem or defect is a minor error, incorrect behavior, or
        a documentation error that in no way impedes the operation of a system.

        Resolution of Severity 4: Fixes for severity 4 bugs will be added to the
        priority list for the next major scheduled release of the product. The
        order of priority for resolving severity 4 issues will be assigned
        jointly by the Customer and MPOWER.

                                    EXHIBIT H

                       PSI REQUESTED CUSTOMER ENHANCEMENTS

1. Bar Coding Capabilities/Document Control Tracking (priority_ for business
flow)

        Ability for system to accept a bar code number from the claim form.

        Bar code number would contain the document control number for tracking
        and filing purposes.

        The bar code number would be used for filing under a document imaging
        system.

        PSI will need to be able to capture a 15 digit document control number
        to identify the following:

                - Julian date for claim received at PSI

                - IPA identifier

                - Plan identifier

                - Line of business

                - Type of claim

2. Provider File

        Ability to capture notes by provider (under provider file)

        Termination dates for providers. Very important, we do not want to be
        assigning members to or paying capitation and claim on a terminated
        provider.

        Add Provider fax number and e-mail address to provider file.

3. Percent of Premium Calculation

        Due to the expected growth of the PSI business, it is imperative that
        the system be able to calculate percent of premium. The current manual
        calculation outside the system will not accommodate the growth
        expectations.

4. UB-92 Requirements (priority _to meet delegated requirement)

        Must capture the following data in order to meet the strict reporting
        requirements of the Plans, HCFA, and the State of Washington MAA:

                - Principal ICD-9-CM diagnosis code and nine additional
                  secondary ICD- 9-CM diagnosis codes.


                                 Page 37 of 40
<PAGE>   38

        - Principal ICD-9-CM procedure code and 5 additional secondary ICD-9- CM
          procedure codes.

          DRG codes.

          DRG Grouper type and version, should be date of service sensitive.
          Ability to track DRG codes and grouper version to Plan/line of
      business.
          Newborn birth weight.
          Type of bill
          Admit/Discharge date
          Admit/Discharge hour
          Attending physician name
          Capture revenue codes and CPT codes together (Medicare and
      Washington State Medicaid requirement).
          Process CPT code modifiers on the UB-92 (new 1998 requirement for
      Medicare)

5. Separate screens for UB-92 (inpatient and outpatient) and HCFA-1500

6. Referral/Authorizations

        Ability to track appeals and grievances against a referral.
        Track referral turn around times by:

        - First date stamp
        - Date entered into MPower
        - Date deferred
        - Date notes received on deferred referral
        - Date reviewed again on deferred referral
        - Date approved or denied

        Ability to capture if the specialist has referred on for additional
      services
        Negotiated rates.
        If referral is elective or emergent.
        One screen.

7. Original Stamp Date on Claim

        Necessity to capture an "original stamp date" or 'original receipt date"
        which can be different from the document filing stamp date that is
        contained in the Julian Date sub-field portion of the Claim Number
        field. Since PSI is fully delegated by HMO insurance companies, claims
        received by the upstream insurance company must be honored for
        calculating the interest' due for Medicare claims received from
        non-contracted providers that are paid more slowly than Medicare
        regulations permit.


                                 Page 38 of 40
<PAGE>   39

        Reporting needs to calculate the time elapsed from "original receipt
        date" to the "document filing stamp date", which is the date that the
        downstream MSO has received the claim.

        Dates that claim is entered, set-to-pay and paid are already captured in
        the system as well as the document filing stamp date (within claim
        number scheme)

                       Pre-Requisite Hardware and Software
             for the Initial Release of MPOWER(TM) on an NT Server

Products required:

For the NT Server are

        1.)    IBM's Transaction Server for Windows NT (CICS operating system)
               version 4.02

        2.)    MicroFocus's COBOL version 4.0.32.

        3.)    IBM's DB2 Universal Developers Edition for NT version 5.0

For an NT Client (PC running either Win95 or NT - 32bit OS):

        1.)    MultiSoft's WCL Toolkit version 5.0 32bit - WCL is the
               communication interface product that passes data from a 3270
               emulator to VB.

        2.)    Wall Data's Rumba for the Mainframe Win95/NT Client version
               5.1uol - Rumba provides 3270-compatable connectivity to a host
               computer. (Version 5.2 is scheduled for release mid-1st quarter
               which we will be upgrading to)

        3.)    IBM's DB2 Client Setup Version 5.0 - Allows for ODBC connectivity
               to back end databases.

For the client to communicate with the server:

        Communication protocol is via TCP/IP, so the clients need to networked,
        32 bit OS, PCs. The server machine should have at least the hardware
        recommended by Microsoft for running the NT 4.0 Server operating system
        and should also be attached to the network.

As MPOWER finalizes the testing of the MPOWER NT system, MPOWER will be firming
up installation, implementation, and requirements guides.

    agreements, as appropriate. In addition, MPOWER and CONTRACTOR agree to be
    joined in any dispute between Customer and a Contracted Health Plan
    involving administrative services rendered by MPOWER and CONTRACTOR pursuant
    to this Agreement, and to cooperate fully in the resolution of such dispute
    in accordance with the dispute resolution procedure set forth in the
    applicable Health Plan Agreement.

2.  DISPUTE BETWEEN THE PARTIES. If any dispute shall arise between the parties
    in connection with this Agreement that is [unrelated to a Member, provider,
    or Contracted Health Plan complaint], the parties shall make every effort to
    amicably resolve the dispute pursuant to this Section V.2. The following
    procedures shall be adhered to in order to expeditiously resolve any
    disputes arising during the term of this Agreement.

    A.  The party invoking the procedures of this Section V.2 shall provide
        written notice to the other party. Each party shall designate an
        individual empowered to bind the organization to a negotiated resolution
        of the dispute. Unless the dispute is resolved with fewer meetings,
        these parties shall meet and confer at least two (2) times within
        forty-five (45) days to attempt to reach such resolution. If the matter
        has not been resolved informally within such forty-five (45) days (which

                                      -7-
<PAGE>   8

        period may he extended by mutual agreement), the dispute shall be
        settled by binding arbitration in accordance with the provisions of
        Sections B through G of this Section V.2.

    B.  Either party may commence arbitration by sending a written demand for
        arbitration to the other party, setting forth the nature of the
        controversy, the dollar amount involved, if any, and the remedies
        sought, and attaching a copy of this Article V to the demand. The
        parties shall attempt to agree upon either one or three (3) arbitrators,
        as they jointly deem appropriate. If the parties fail to agree upon the
        appropriate number of arbitrators and the identity of the arbitrator(s)
        within ten (10) days after the demand for arbitration is mailed, then
        the parties stipulate to arbitration before three (3) neutral
        arbitrators sitting on the JAMS/Endispute ("JAMS") panel administered by
        the Denver, Colorado, JAMS office. Each party shall select one such
        arbitrator from the panel, and the third arbitrator shall be selected by
        the first two so selected. All three arbitrators shall be neutrals, and
        no arbitrator shall have a conflict of interest unless waived by both
        parties.

    C.  The parties shall share all costs of arbitration. Each party shall be
        responsible for its own legal fees.

    D.  The arbitrator(s) shall apply the substantive law of Colorado. The
        parties shall have the rights of discovery as provided for any judicial
        proceeding. The Colorado evidence code shall apply to testimony and
        documents submitted to the arbitrator(s).

    E.  Arbitration shall take place in Denver, Colorado unless the parties
        otherwise agree. As soon as reasonably practicable, the arbitrator(s)
        shall conduct a hearing on the dispute or matter to be resolved. As soon
        as reasonably practicable thereafter, the arbitrator(s) shall arrive at
        a final decision, which shall be reduced to writing, signed by the
        arbitrator(s) and mailed to each of the parties and their legal counsel.

    F.  All decisions of the arbitrator(s) shall be final, binding and
        conclusive on the parties and shall constitute the only method of
        resolving disputes or matters subject to arbitration under this
        Agreement. The arbitrator(s) or a court of appropriate jurisdiction may
        issue a writ of execution to enforce the arbitrator's judgment. Judgment
        may be entered upon such a decision in accordance with applicable law in
        any court having jurisdiction.

    G.  Notwithstanding the foregoing, because time is of the essence of this
        Agreement, the parties specifically reserve the right to seek a judicial
        temporary restraining order, preliminary injunction, or other similar
        short term equitable relief, and grant the arbitrator(s) the right to
        make a final determination of the parties' rights, including whether to
        make permanent or dissolve such court order.

                            VI. TERM AND TERMINATION

1.  TERM. The initial term of this Agreement shall commence on the Effective
    Date hereof and shall continue for a period of five (5) years unless sooner
    terminated in accordance with this Article VI. Thereafter, this Agreement
    shall automatically renew for consecutive one (1) year periods.

2.  TERMINATION WITHOUT CAUSE. This Agreement may be terminated without cause by
    either party by providing one hundred twenty (120) days' prior written
    notice to the other party.

3.  TERMINATION FOR CAUSE. This Agreement may be terminated immediately upon

    A.  Except as provided in Section 4.B below, either party may terminate this
        Agreement upon failure of the other party to cure non-compliance with
        any material provision of this Agreement within thirty (30) days after
        the terminating party gives written notice of such non-compliance to the
        other party, unless cure of the non-compliance cannot be reasonably
        completed within thirty (30) days, in which case such cure shall be
        commenced within such thirty (30) day period and diligently pursued to
        completion, which completion shall occur no later than forty-five (45)
        days after the initial notice of termination. Any such termination shall
        be effective as of the date of expiration of the applicable cure period.

        certifications required for CONTRACTOR to perform its obligations
        hereunder.

    B.  In the event of any material adverse change in CONTRACTOR'S insurance
        coverage, MPOWER may immediately terminate this Agreement.

        CONTRACTOR with not less than forty-five (45) days' notice of such
        termination.

    D.  This Agreement may be terminated if either party becomes insolvent, or
        is adjudicated as bankrupt, or its business comes into possession or
        control, even temporarily, if any trustee in bankruptcy, or a receiver
        is appointed for it, or it makes a general assignment for the benefit of
        creditors, and no interest in this Agreement shall be deemed an asset of
        creditors.

5.  EFFECT OF TERMINATION. Upon termination of this Agreement for any reason,
    the Agreement shall be of no further force or effect, except as to the
    rights and obligations of the parties arising out of transactions occurring
    prior to the effective date of termination. MPOWER and CONTRACTOR shall
    cooperate fully with Customer and all Contracted Health Plans to ensure a

        on diskette, all data, records, and other information connected with

2.  CUSTOMER SATISFACTION SURVEYS. Customer may periodically conduct "customer"
    satisfaction surveys of policyholders, Contracted Health Plans, and
    providers with whom Customer has contracted. CONTRACTOR agrees to record all

    provide other reasonable support to Customer's customer satisfaction survey
    activities as requested,

    its errors and omissions coverage, the other will be notified of the
    occurrence. In the event any such coverage is provided on a claims made
    basis, such coverage shall be manufactured (or such party shall procure
    equivalent tail coverage) for a period of five (5) years after the
    termination hereof.

4.  BUSINESS RELATIONSHIP. The business relationship of CONTRACTOR to MPOWER

      the MPOWER Product, and methodologies related thereto ("Proprietary
      Information") are the exclusive property of MPOWER or MPOWER's suppliers
      and that the Proprietary Information is confidential, has tangible value
      and includes trade secret information of MPOWER and/or MPOWER's suppliers.
      MPOWER and/or MPOWER's suppliers shall retain all rights to the

      such disclosure was made to Customer) and, prior to any such disclosure or
      access, Customer and such third party must enter into a nondisclosure
      agreement with MPOWER in substantially the form set out in the Addendum
      which is attached to this Master Agreement and made a part hereof. In no
      event shall Customer disclose any Proprietary Information to any
      competitor of MPOWER.

      Customer and MPOWER specifically acknowledge that specific provider and
      benefit contract rates, the names, demographic information, contractual
      relationships, and medical information of any group, member, provider or

      contracted with Customer, unless such information is available through
      public sources or through publicly available filings with any insurance or
      health care regulatory agency or with any industry accreditation or
      reporting body.

      Further notwithstanding the above, Customer and MPOWER acknowledge that
      Customer may create and distribute reports and data from its licensed use
      of the MPOWER Products in the normal course of its business to its
      customers, to health care providers, Enrollees, employers or Plan
      Sponsors, government agencies and others with a legitimate purpose in the
      conduct of the Customer's business and the data processed by the licensed
      MPOWER Products, and that such reports and distributed data do not
      constitute Derivative Works, unless they are used to create commercial
      software products for reuse and / or license to other parties.

      Customer and MPOWER agree that MPOWER has no rights in the data that is
      input by Customer or its agents in the use of the MPOWER Products, and
      agree that all of such data, and any subsequent information developed from
      such data by Customer in its use of the MPOWER Products is confidential
      information solely for the use of Customer. MPOWER shall not use the data
      and subsequent information developed by Customer in any manner, and it is
      agreed that such data and information is Proprietary Information of
      Customer.

III.  COPYING

      Customer, for each licensed instance of the MPOWER Product being used in a
      Live Production Environment, may make one (I) copy of each MPOWER Product
      in machine-readable form in a test region for the purpose of testing new
      releases or


                                  Page 6 of 43
<PAGE>   7
      fixes and also one (1) copy of each MPOWER Product in machine-readable
      form for backup purposes only. Customer agrees that upon copying any
      MPOWER Product, Customer shall place a label on the outside of each copy
      medium showing the program name, version number and any/all copyright and
      proprietary notices in the same form as contained on the original copy.

      In addition, Customer may make automated backup copies of its production
      and testing regions for operational backup purposes without applying the
      above labels, provided that such operational backup copies are maintained
      with the acceptable industry standard security measures and not made
      available to outside parties except for the case of disaster recovery
      purposes, in which case the disaster recovery agent will be bound to all
      the confidentiality and Proprietary Information restrictions to which
      Customer is bound hereunder, and further that no such disaster recovery
      agent may be a competitor of MPOWER.

IV.   SOURCE CODE ESCROW

      At the request of Customer, MPOWER and Customer will enter into an
      agreement with MPOWER's escrow agent ("Custodian") for the depositing of
      the MPOWER Products' Source Code ("Source Code Copy"). [The current
      Custodian is NORWEST Bank.] MPOWER shall notify Customer at least ten (10)
      business days prior to a change in the entity identified as the Custodian.
      Subject to Customer's payment of all fees due under this Agreement in
      accordance with the applicable payment terms and Customer's payment of all
      fees related to' Custodian's administration of said escrow (the current
      rate as of the date of this Agreement being One Thousand Five Hundred
      ($1,500.00) Dollars per annum), the Source Code Copy so deposited will be
      maintained during the period Customer shall use and purchase, and MPOWER
      shall provide, software maintenance services for the particular MPOWER
      Product. The Source Code Copy will be updated by MPOWER within thirty (30)
      days after each new Release of the particular MPOWER Product.

      The parties agree that the Source Code Copy shall be held by the Custodian
      for delivery to Customer under the conditions that this Agreement is
      terminated as a result of a material breach of the terms of this Agreement
      by MPOWER or MPOWER riles for bankruptcy under Chapter 7, and its business
      is not continued by virtue of a merger, consolidation, the sale of all or
      substantially all of its assets, or through some other transaction by
      another fiscally sound and technically qualified corporation or entity,
      and the Custodian of the Source Code has received from Customer or from
      MPOWER, or from a court of competent jurisdiction: (i) written
      notification of any such event or condition; (ii) demand that a copy of
      the Source Code Copy be mailed to Customer; (iii) written undertaking from
      Customer, which shall be legally binding, that the copy 'of the Source
      Code Copy to be supplied to Customer will be used only for Customer's
      maintenance of the


                                  Page 7 of 43
<PAGE>   8
      MPOWER Products at a specified location and will be promptly returned to
      the Custodian at the expiration of the period during which Customer, under
      its agreement with MPOWER, has the right to use the MPOWER Products, and
      that the copy of the Source Code and the information and material
      contained therein shall be held confidentially by Customer, its employees
      and agents who are involved in the use and technical maintenance of the
      MPOWER Products, and shall not, under any circumstances, be disclosed or
      made available to any other person or entity; and (iv) specific
      instructions from Customer for the delivery of a copy of the Source Code
      Copy, with a copy of such instructions to MPOWER. Customer will pay the
      costs and expenses of the Custodian in carrying out the requirements of
      this Section.

      In addition, if Customer uses the MPOWER Product Source Code, it will only
      be for the purposes for which the Object Code is licensed under this
      Agreement and not for re-license, reverse engineering or to create a
      derivative product. The Confidential and Proprietary Information
      provisions of Section II apply also to the Source Code.

V.    TERMINATION

      Should Customer fail to pay any sum due and payable under this Agreement,
      MPOWER shall notify Customer in writing of such failure to pay. Customer
      shall then have thirty (30) days from the delivery of MPOWER's written
      notice to pay such amount(s). The foregoing sentence in no way relieves
      Customer from its obligation to pay any and all late charges which may
      become due as set forth in Section VI below. If payment is not made within
      such thirty (30) days, MPOWER shall have the immediate right to
      discontinue any and all services under this Agreement. Furthermore, if
      payment is not made within sixty (60) days from the delivery of MPOWER's
      written notice, MPOWER shall have the immediate right to terminate this
      Agreement, except that the License granted hereunder shall not be
      terminated unless the sum due and unpaid is specifically for the License
      granted hereunder.

      Should either party commit a material breach of its obligations under this
      Agreement, other than failing to pay money, the non-breaching party may
      notify the breaching party in writing, setting out the breach, and the
      breaching party shall have thirty (30) days to remedy such breach. If the
      breaching party fails to remedy the breach during this thirty (30)-day
      period, or, with respect to those breaches which cannot reasonably be
      remedied within thirty (30) days, if the breaching party fails to proceed
      promptly after being given such notice to commence remedying the breach
      and thereafter to diligently proceed to remedy the same, the other party
      shall have the right to terminate this Agreement, provided such party
      gives the breaching party ten (10) days' prior written notice to that
      effect. Notwithstanding the foregoing, either party shall have the right
      to


                                  Page 8 of 43
<PAGE>   9
      immediately terminate this Agreement upon any breach by the other of its
      obligations under Section II above.

      Termination of this Agreement shall be without prejudice to all accrued
      rights and remedies either party may have and shall not affect any
      continuing rights and obligations of the parties under this Agreement.

      Upon the termination of this Agreement and/or any Attachment to this
      Agreement, Customer shall return to MPOWER all Proprietary Information
      regarding the MPOWER Product whose license is being terminated, within
      thirty (30) days after such termination and MPOWER shall return to
      Customer any proprietary information obtained in the performance of this
      Agreement within thirty (30) days after such termination.

      Notwithstanding anything to the contrary herein, the License granted
      hereunder shall not be terminated due to any breaches that relate to
      Software Maintenance services; Implementation services; Training services;
      Conversion services and/or Other services as identified in this Agreement
      or the Attachments hereto. In the instances of such breaches MPOWER'S
      termination remedies shall be limited to termination of this Agreement as
      it applies to such services.

VI.   INVOICES AND CHARGES

      Unless a specific payment date is set out in an Attachment to this
      Agreement, Customer agrees to remit all payments under this Agreement so
      that MPOWER shall receive such payments no later than thirty (30) days
      from the date of Customer's receipt of MPOWER's invoice. Customer also
      agrees that MPOWER shall have the right to charge interest of one percent
      (1.0%) of the outstanding balance per month, and Customer agrees to pay
      such charges if assessed. All prices mentioned in this Agreement are in
      U.S. Dollars. The parties agree that the prices set out in this Agreement
      do not include any sales, use or gross receipts taxes, any duties, any
      similar assessments, or any other tax imposed on any party by virtue of
      this Agreement, all of which, excluding only taxes based on MPOWER's
      income, shall be the sole liability of, and shall be paid solely by,
      Customer.

VII.  FORCE MAJEURE

      Neither party shall be liable to the other for failing to fulfill any
      obligation under this Agreement if such failure is caused by an event
      which is beyond such party's reasonable control and which is not caused by
      such party's fault or negligence, including without limitation, acts of
      God, acts of war, fires, strikes, lightning, floods, epidemics, civil
      unrest, power shortages, a third party's equipment failure,


                                  Page 9 of 43
<PAGE>   10
      delays in transportation, or either party's inability to obtain necessary
      labor, material or components due to causes beyond such party's reasonable
      control.

VIII. CUSTOMER RESPONSIBILITIES

      A.    Customer Responsibilities

      Customer acknowledges that MPOWER(R) reflects certain interdependent
      relationships, such as exist among the data variables, logic rules and
      system functions of MPOWER(R). Customer further acknowledges that it is
      required and has a responsibility to understand such data variables, logic
      rules and system functions, and their interdependent relationships, and to
      define for its own purposes such data variables, logic rules and system
      functions to MPOWER(R) in such a way that MPOWER(R) will provide the
      functionality desired by Customer. Customer acknowledges that it has or
      will hire and will maintain on its staff personnel who are able to
      understand and define such data variables, logic rules, system functions
      and interdependent relationships. Customer further acknowledges that, even
      though MPOWER may assist Customer personnel in performing these tasks, the
      responsibility for the effective definition and maintenance of these data
      variables, logic rules and system functions resides with Customer and not
      with MPOWER, unless Customer specifically requests MPOWER to perform these
      tasks at agreed upon rates specified in a Work Order.

      B.    Customer Data

      Customer shall be responsible for inputting and ensuring the accuracy,
      validity and completeness of all data variables, logic rules, system
      functions and Customer data, including but not limited to group,
      subscriber, member, provider, utilization, encounter, claims, capitation,
      fund accounting, billing, collection, broker, benefits, product contract,
      provider contract, provider fees, standard business measures, and other
      similar or related data. Customer shall also be responsible for inputting
      and ensuring, the accuracy, validity and completeness of all user-defined
      report definitions, all report and batch production job specifications and
      priority scheduling criteria. Customer shall also be responsible for
      initiating, monitoring, operating, printing and ensuring the accuracy,
      validity, and completeness of all print outputs and file downloads, such
      as but not limited to all reports, premium bills, checks, and the like,
      determining how many and on what print stock such outputs are to be
      printed or into which files or programs on Customer-controlled computers
      such files are to be downloaded and manipulated, at Customer's own
      initiative, responsibility and risk. Customer hereby acknowledges
      responsibility for generally controlling all aspects related to the
      production, distribution and control of such outputs. Customer further
      acknowledges that, notwithstanding the responsibility of MPOWER to have
      used


                                  Page 10 of 43
<PAGE>   11
      due care and diligence in the design, programming, documentation and
      operation of the System, the accuracy of Customer's data base within
      MPOWER(R) and the accuracy of the several outputs of the MPOWER(R),
      including but not limited to, outputs that control the billing, receipt or
      expenditure of monies, will be dependent on the accuracy and use of the
      data variables, logic rules, system functions and Customer data input into
      MPOWER(R) by Customer and verified by Customer.

      C.    Other Customer Obligations

      In addition to its other obligations hereunder, Customer will on a timely
      basis:

            1.    Establish appropriate priorities for Customer, on a regular
                  basis and no less frequently than every ninety (90) days, that
                  relate to MPOWER(R) and communicate the same to MPOWER.
                  Customer recognizes that changes in such priorities may result
                  in additional fees hereunder for additional staff, as
                  incremental support, or reordering of other priorities to
                  provide MPOWER services within the current fee structure.

            2.    Cooperate with MPOWER by, among other things, making
                  available, as reasonably requested by MPOWER, management
                  decisions, information, approvals, and acceptances in order
                  that MPOWER may properly accomplish its obligations and
                  responsibilities hereunder.

            3.    Carefully inspect and review all MPOWER generated reports and
                  other output and notify MPOWER of any incorrect reports or
                  output.

            4.    Personalize, maintain, reproduce and distribute (solely for
                  Customer's internal use) procedure manuals and documentation
                  used by Customer personnel in connection with the MPOWER
                  services hereunder.

            5.    Train applicable Customer personnel to properly prepare input
                  for and to effectively utilize output from the systems
                  operated by MPOWER hereunder.

            6.    Pay all costs of acquisition, installation, use and
                  maintenance of equipment at Customer's site, as required for
                  the performance of MPOWER services.

            7.    Such other responsibilities as set forth herein.

      Customer agrees that to the extent its failure to meet its obligations set
      forth in this Section VIII C affects the ability of MPOWER to perform
      MPOWER's obligations under this Agreement, MPOWER shall be relieved of
      such


                                  Page 11 of 43
<PAGE>   12
      obligations, and Customer shall indemnify MPOWER against any claims or
      liabilities arising, out of such failure by Customer, subject to the
      liability limitations set forth elsewhere herein.

      D.    Reprocessing or Reconstructing of Data

      During any period of use of MPOWER(R), to the extent that any Customer
      data must be corrected, recreated, restored or reprocessed due to the
      fault or negligence of Customer, its employees or agents, or by a breach
      by Customer of any of its obligations hereunder, MPOWER will do so, and in
      such event Customer shall pay MPOWER at the service fee rates outlined in
      an applicable Work Order and reimburse MPOWER for any reasonable direct
      costs incurred by MPOWER in correcting, recreating, restoring or
      reprocessing such data or in providing assistance therewith.

IX.   LIMITATION OF LIABILITY

      CUSTOMER AGREES THAT MPOWER SHALL HAVE NO LIABILITY TO CUSTOMER FOR
      INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES, EVEN IF MPOWER IS ADVISED
      OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR LOSS OF USE OR OTHER COMMERCIAL
      LOSS (INCLUDING, BUT NOT LIMITED TO, LOSS OF REVENUES AND/OR PROFITS),
      HOWEVER OCCASIONED AND WHATEVER THE FORM OF ACTION, FOR ACTUAL OR IMPUTED
      NEGLIGENCE, BREACH OF CONTRACT, BREACH OF WARRANTY OR OTHERWISE.

      FURTHERMORE, CUSTOMER AGREES THAT IN NO EVENT SHALL MPOWER BE LIABLE FOR
      DIRECT DAMAGES IN EXCESS OF ALL FEES CUSTOMER SHALL HAVE PAID MPOWER UNDER
      THIS AGREEMENT.

      The parties agree that no action, regardless of form, which may arise out
      of the transactions under this Agreement may be brought by either party
      more than two (2) years after the cause of action is known, or ought
      reasonably to have been known, to the party bringing the action.

      MPOWER AGREES THAT CUSTOMER SHALL HAVE NO LIABILITY TO MPOWER FOR
      INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES, EVEN IF CUSTOMER IS ADVISED
      OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR LOSS OF USE OR OTHER COMMERCIAL
      LOSS (INCLUDING, BUT NOT LIMITED TO, LOSS OF REVENUES AND/OR PROFITS),
      HOWEVER OCCASIONED AND WHATEVER THE FORM OF ACTION, FOR ACTUAL OR IMPUTED
      NEGLIGENCE, BREACH OF CONTRACT, BREACH OF WARRANTY OR OTHERWISE.


                                  Page 12 of 43
<PAGE>   13
X.    INFRINGEMENT

      MPOWER agrees to defend, indemnify and hold Customer harmless against any
      and all claims that any MPOWER Product infringes a U. S. Letter Patent,
      copyright, trade secret or the proprietary fights of others, provided that
      MPOWER, shall have received timely written notice of any such claim and
      that MPOWER shall have sole control of the defense of such claim and all
      negotiations for the settlement or compromise of such claim.

      As of the date first written above, MPOWER warrants that it is not aware
      of any infringement, and has not been notified by any third party that it
      may be infringing, any U.S. Letter Patent, copyright, trade secret or the
      proprietary fights of others.

      If use of an MPOWER Product by Customer is enjoined, or becomes, or, in
      MPOWER's sole opinion, is likely to become, the subject of a claim of
      infringement, MPOWER will, at its option and expense, either:

      1.    procure for Customer the right to continue using the MPOWER Product
            in question; or

      2.    replace or modify the same so that it is functionally equivalent
            [i.e. the MPOWER Product will achieve the same or similar business
            logic result] (or contains more functionality) and is
            non-infringing.

      Notwithstanding the foregoing, if MPOWER determines that neither of the
      alternatives set forth above is reasonably available, MPOWER will refund
      to Customer any unamortized portion of the infringing MPOWER Product's
      license fee which has then been paid by Customer. Amortization shall be
      based upon a seven (7)-year life of the infringing MPOWER Product,
      beginning on the date the infringing MPOWER Product was licensed by
      Customer from MPOWER. Should such refund occur, Customer agrees to return
      the infringing MPOWER Product to MPOWER.

      Should any refund described above occur, the license for the infringing
      MPOWER Product shall be terminated and MPOWER, its affiliates,
      subsidiaries, assigns and successor corporations shall be released from
      any and all liability arising from any and all claims, losses,
      liabilities, damages, costs or deficiencies which are then-existing or
      which may arise in the future with regard to such infringing MPOWER
      Product(s) for which MPOWER has refunded fees pursuant to this Section X.

      Notwithstanding anything contained herein to the contrary, MPOWER shall
      have no liability for any loss, cost, claim or expense caused by:


                                  Page 13 of 43
<PAGE>   14
      1.    alteration of any MPOWER Product provided hereunder by any party
            other than MPOWER;

      2.    any loss, expense or liability resulting from any infringement which
            is a consequence of MPOWER's compliance with designs or code
            submitted to MPOWER by Customer;

      3.    the use of any MPOWER Product in combination with products not
            licensed to customer by MPOWER;

      4.    continuation of the allegedly infringing activity by Customer after
            Customer is notified in writing thereof and after the conclusion of
            a reasonable grace period afforded Customer in the notice to migrate
            from the infringing activity to an alternate solution; or

      5.    Customer's use of an MPOWER Product other than in compliance with
            the terms and conditions of this Agreement.

      Notwithstanding the foregoing, MPOWER shall not be obligated to defend,
      indemnify or hold Customer harmless from and against any claim, suit
      proceeding or allegation asserted by a parent, subsidiary or affiliate of
      Customer.

      The foregoing remedy set forth in this Section X represents the exclusive
      remedy of Customer and MPOWER's sole liability with regard to any claim
      that an MPOWER Product infringes the rights of others.

XI.   RESOLUTION OF DISPUTES

      If any dispute shall arise between the parties under this Agreement, the
      parties shall make every effort to amicably resolve the dispute by
      providing written notice of the dispute, setting forth the nature of the
      dispute in sufficient detail for the other party to evaluate the matter
      and respond to the claims of the other party. The other party will provide
      a written response in reasonable detail (to the extent allowable based on
      the sufficiency of details provided by the notifying party), within a
      reasonable time, but no greater than 30 business days after receipt of
      such notice, to the allegations of the notifying party. If the parties are
      unable to resolve the dispute within 30 business days of the receiving
      party's response to the notifying party, then the parties may seek to
      invoke the arbitration provision set forth below.

      If the matter has not been resolved pursuant to the aforesaid dispute
      resolution procedures (which may be extended by mutual agreement) the
      controversy shall be settled by arbitration in accordance with the
      American Arbitration Association.


                                  Page 14 of 43
<PAGE>   15
      (the "Association) under the Commercial Arbitration Rules of the
      Association then in effect, by an arbitrator knowledgeable in the computer
      area. The arbitrator shall be selected by mutual agreement of MPOWER and
      Customer. If MPOWER and Customer can not agree upon an arbitrator, an
      arbitrator shall be appointed by the Court with jurisdiction over the
      dispute. The arbitration shall be governed by the United States
      Arbitration Act, 9 U.S.C. Sec. 1-16, and judgment upon the award by the
      arbitrator may be entered by any court having jurisdiction thereof. The
      place of arbitration shall be in Bergen County, New Jersey. Each party
      shall pay its own costs and expenses.

XII.  SUCCESSORS AND ASSIGNS

      This Agreement shall be binding upon and shall inure to the benefit of the
      parties and their respective successors and (to the extent specified in
      any assignments) assigns. Customer shall not assign or otherwise transfer
      this Agreement without the prior written consent of MPOWER. Customer,
      however, may assign this Agreement to any subsidiary or affiliate of
      Customer in which Customer owns an equity position of 51% or more, or to
      any successor company to Customer in the event that Customer conveys
      substantially all of its assets (or stock) to, or merges with, another
      Company, by giving notice to MPOWER within 30 days of any such conveyance.

XIII. OMNIBUS RECONCILIATION ACT COMPLIANCE

      As applicable under the Omnibus Reconciliation Act of 1980, until the
      expiration of four (4) years after the furnishing of services under this
      Agreement, MPOWER shall, upon receipt of written request, and if then
      required to make such information available under the then-existing law,
      make available to the Secretary of the United States Department of Health
      and Human Services ("Secretary"), the Comptroller General, or any of their
      duly authorized representatives, this Agreement, books, documents, and/or
      records of MPOWER that are necessary to certify the nature and extent of
      products and services delivered under this Agreement and costs associated
      therewith. Furthermore, if MPOWER carries out any of the duties of this
      Agreement through a subcontract with a value or cost of Ten Thousand
      Dollars ($10,000.00) or more over a twelve (12)-month period, such
      subcontract will contain a clause to the effect that, until the expiration
      of four (4) years after the furnishing of such services under such
      subcontract, the subcontractor shall, upon receipt of written request and
      if then required to make such information available under the
      then-existing law, make available to the Secretary, Comptroller General,
      or any of their duly authorized representatives, the subcontract, books,
      documents, and/or records of such subcontractor that are necessary to
      verify the nature and extent of such costs.

XIV.  RELATIONSHIP MANAGEMENT

      A.    Meetings. MPOWER and Customer agree to discuss business and
            relationship strategies affecting both parties, as is required to
            effectively manage the relationship between the parties. MPOWER and

      therein stipulated, and by providing the number of such additional

IV.   WARRANTY

      A.    General Terms

      M-POWER represents and warrants to Customer that MPOWER(R) will function
      in accordance with the Documentation in all ways which materially affect
      the performance of MPOWER(R) Products. Tiffs warranty is contingent upon
      Customer's using: 1) certain prerequisite hardware and software, a list of
      which has been provided to Customer by MPOWER (Exhibit H) for the Windows
      NT Release; and 2) the most recent Release of MPOWER(R), provided such
      Release has been available for Customer's use for thirty (30) days, or
      more. If Customer wishes to use certain third party software that is
      similar to but not the MPOWER defined "prerequisite software" to perform
      the functions required by such "prerequisite software", MPOWER and
      Customer agree to negotiate in good faith under an appropriate Work Order
      for MPOWER to certify whether such third party software will qualify as
      "prerequisite software" which is a contingency to the warranties herein.
      MPOWER further represents and warrants that MPOWER owns the MPOWER
      Products, that it has the right to grant the licenses granted hereunder
      without violating the rights of any third parties, and that the licenses
      are free and clear of all liens and encumbrances, other than security
      interests related to financial instruments between MPOWER and lending
      institutions.

      B.    Year 2000 Compliance

      MPOWER represents and warrants that the MPOWER Product(s) subject to the
      Agreement shall be Year 2000 Compliant. Year 2000 Compliant means that
      performance and functionality is not affected by dates prior to, during,
      and after January 1, 2000. Specifically: no value for current dates will
      cause any interruption in operation; date-based functionality must behave
      consistently for dates prior to, during and after January 1, 2000; in all
      interfaces and data storage, the century in any date should be specified
      explicitly (CCYY); the Year 2000

* Confidential Treatment Requested

                                  Page 22 of 43
<PAGE>   23
      must be recognized as a leap year.

      In the event the MPOWER Product(s) require(s) modification to prevent
      MPOWER from being in breach of the foregoing warranty, MPOWER represents
      and warrants to Quest Diagnostics that it will immediately assign Senior
      engineering staff to work continuously until such software program is
      returned to the same level of functionality as warranted herein at no
      charge to Quest Diagnostics, time being of the essence.

      In the event MPOWER breaches the foregoing warranty, MPOWER shall defend,
      indemnify and hold harmless (including reasonable attorney's fees) Quest
      Diagnostics, its employees, officers, and directors against all costs,
      expenses, and liability arising from or in connection with such breach,
      however such indemnification is limited to the sum equal to two (2) times
      the sum of all payments made to MPOWER under this agreement.

      MPOWER shall also provide Quest Diagnostics, free of charge, with any new
      versions, upgrades, etc. of all software which prevents or corrects a
      breach of warranty.

      The obligations of this section shall survive the termination of the
      Agreement.

      MPOWER hereby grants to Quest Diagnostics a limited use source code
      license for MPOWER Products to be used by Quest Diagnostics or a third
      party vendor for the sole purpose of testing for Year 2000 compliance.

      The foregoing is Customer's sole and exclusive remedy for breach of
      warranty. The warranty set forth above is made to and for Customer's
      benefit only. The warranty will apply only if no modification, alteration
      or addition has been made to MPOWER(R) by persons other than MPOWER or
      MPOWER's authorized representative.

      THE WARRANTY SET FORTH IN THIS SECTION IV CONSTITUTES THE ONLY WARRANTY
      PROVIDED BY MPOWER REGARDING MPOWER AND SUCH WARRANTY IS IN LIEU OF ALL
      OTHER WARRANTIES, WRITTEN OR ORAL, STATUTORY, EXPRESS, OR IMPLIED. MPOWER
      HEREBY SPECIFICALLY DISCLAIMS THE IMPLIED WARRANTY OF MERCHANTABILITY AND
      THE WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

            Any on-site assistance which Customer may request and which is
            provided by MPOWER, which, in MPOWER's and Customer's reasonable
            opinions, is not necessary to determine the nature and resolution of
            any problems Customer may have with MPOWER(R)shall be provided by
            MPOWER at its then-current rates. If Customer notifies MPOWER that
            it suspects a material error in the program logic of MPOWER(R)or in
            the Documentation, MPOWER shall make all reasonable efforts to
            confirm the existence of the error and correct it. If the parties
            mutually determine that no such error exists, Customer agrees to pay
            MPOWER for its services at MPOWER's hourly rates then in effect and
            to reimburse MPOWER for any and all reasonable travel and living
            expenses incurred by MPOWER in rendering such services. MPOWER will

            access to the system console to handle such activities as
            coordination of hardware troubleshooting, network/security
            administration and backups/loading of tapes.

                                 Page 24 of 43
<PAGE>   25
      Notwithstanding the foregoing, should Customer be utilizing any Release of
      MPOWER(R) other than the then-most-recent Release, or the Release prior to
      the then-most-current Release, provided such Release has been available
      for Customer's use for a period of six (6) months or longer, MPOWER
      reserves the right, at its sole option, to terminate its obligations to
      provide maintenance services under this Section V at any time upon giving
      thirty (30) days' prior written notice to Customer. If such a condition
      exists, MPOWER and Customer agree to negotiate in good faith to define
      reasonable terms, conditions and fees for MPOWER to provide Customer with
      maintenance services for such then non-current Release.

      Section V shall automatically continue, on an annual basis, unless either
      party shall give written notice to the other that it desires not to renew
      such maintenance services. The parties agree that such written notice
      shall be remitted for receipt by the other no less than ninety (90) days
      prior to the end of the then-current annual maintenance period.

            2.    Fees for License Extensions.

            Customer may, during the term of this Agreement, provided Customer
            is current with all Maintenance Fees, exercise an incremental
            license or incremental licenses for claims processing of additional
            [*] encounter files per month ["License Extension(s)"] by paying to
            MPOWER an additional license fee ("License Extension Fee") as shown
            on Exhibit C hereto for each such License Extension.

            The Initial License Fee and the License Extension Fee(s) may be
            referred to as the License Fee(s).

            The License Extension Fees will be billed and paid in accordance
            with the terms and conditions outlined in this Agreement.

      B.    Annual Maintenance Fees.

            Customer agrees to pay to MPOWER for the software maintenance

            Fee") equal to [*] percent ([*]%) of the aggregate of the Initial
            License Fee and all License Fee Extensions paid or payable by
            Customer to MPOWER.

            Extended Support Services described in Section V.D above will be
            provided by MPOWER to Customer at no additional charge to the
            aforementioned Maintenance Fee during the first year of maintenance.
            Subsequent to the first year of maintenance, the fee for Extended
            Support Services will be [*] ($[*]) Dollars per month. Any such
            annual increases in Extended Support Service fees shall not exceed
            the CPI. Customer may elect not to renew Extended Support Services
            pursuant to the notification procedure outlined in Section V above.

            The annual Maintenance Fee is due and payable as follows: the first
            annual Maintenance Fee shall be due and payable upon the occurrence
            of Final Acceptance as indicated in Exhibit A hereto.

            Each subsequent annual Maintenance Fee shall be billed and due
            annually, based on the anniversary date of the first annual
            Maintenance Fee due date. MPOWER will invoice Customer on an annual
            basis for the maintenance fee. Customer agrees to pay such invoices
            within thirty (30) days after Customer's receipt of the invoice.

                   SEVERITY DEFINITIONS AND RESOLUTION PROCESS

- -     SEVERITY 1.

            The problem causes complete loss of service in the production and
      staging environment and work cannot reasonably continue. The problem or
      defect has one or more of the following characteristics:

      >     Data corruption. Physical or logical data is unavailable or
            incorrect.
            Examples: Block format corruption, invalid indices, corruption of
            meta-data, incorrect results.

      >     Critical functionality is not available.

      >     System hangs. The process hangs indefinitely or there is severe
            performance degradation, causing unreasonable waits for resources or
            response, as if the system is hanging,

      >     The entire MPOWER application crashes repeatedly.

      >     Database process or background processes fail and continue to fail
            after restart attempts.

      >     Potential for above occurrences is defined imminent.

      RESOLUTION OF SEVERITY 1: Until the issue is resolved MPOWER Solutions
      will work on Severity 1 around the clock (7x24). As a result of the
      severity, the customer must provide MPOWER with a point of contact during
      the 7x24 period. The customer's point of contact will assist the MPOWER
      customer support and development staff in gathering data, testing fixes in
      the customer's testing legion, and applying fixes to the customer
      production environment.

- -     SEVERITY 2:

            Problem or product defect causes a severe impact on the customer's
      business regardless of customer environment. No workaround is available,
      however operations can continue in a restricted fashion. The problem or
      defect has one or more of the following characteristics:

      >     Business Impact Examples: The customer can handle current volume,
            but will not be able to handle quarter close; At close, customer
            finds totals wrong, but close is not for a few weeks.

      >     Internal software error, causing the application to fail to run to
            completion, or return wrong results, or software error severely
            degrades performance.

      >     Some important functionality is unavailable, yet the system can
            continue to operate in a restricted fashion.

      >     Potential for above occurrences is defined imminent.

      RESOLUTION OF SEVERITY 2: MPOWER Solutions will work on Severity 2 bug
      based on customer assigned priority. Severity 2 fixes will be added in the
      next scheduled maintenance or patch release.


                                  Page 38 of 43

<PAGE>   39
- -     SEVERITY 3.

            Problem or product defect causes minimal impact on the Customer's
      business. The impact of the problem or defect is minor or an
      inconvenience, such as a manual bypass to restore product functionality.
      The problem or defect has one or more of the following characteristics:

      >     A software error for which there is an acceptable workaround.

      >     Software error minimally degrades performance.

      >     Software error or incorrect behavior has minor impact the operation
            of the system.

      RESOLUTION OF SEVERITY 3: Fixes for severity 3 bugs will be added to the
      priority list for the next major scheduled release of the product. The
      order of priority for resolving severity 3 issues will be assigned jointly
      by the Customer and MPOWER.

Mr. Mark Rangell

Highlands Ranch, Colorado 80125

Dear Mark:

         We are pleased to extend to you this offer to join MPOWER in a senior
management role. Following are the terms and conditions of our employment
agreement.

<TABLE>
<S>                        <C>
         TITLE:            Senior Vice President - Sales and Marketing

         BASE SALARY:      $135,000 per annum.

         COMMISSION:       In addition to your base salary you will be eligible
                           for a sales commission based on achieving planned
                           sales department objectives for the MPOWER
                           organization. Although the 1998 revenue plan has not
                           been formalized by MPOWER, we estimate that the
                           revenue objectives for new business will be in the
                           range of $5M to $6M.

                           Your commission sales targets would be devised as
                           follows:

                              1st quarter target = 10% of 1998 goal
                              2nd quarter target = 20% of 1998 goal
                              3rd quarter target = 30% of 1998 goal
                              4th quarter target = 40% of 1998 goal

                           The quarterly commission structure would consist of
                           the following:

                           previous quarter must be made up for in the future
                           quarter, for commission targets to apply.

         EQUITY:           I will recommend to the board of directors that you

                           ownership level of approximately two and one half
                           (2.5%) percent of currently outstanding shares of
                           MPOWER which have been set aside for "new
                           management". The board of directors will make the
                           official grant. In terms of a vesting schedule, 25%
                           of your total options granted will vest in January.
                           1999 upon the one-year anniversary date of your
                           employment, and thereafter will vest monthly over a
                           36-month period on a pro ram monthly basis for the
                           remaining 75% of the total options grant. Under the
                           terms of the stock option plan, should mere be a
                           change of ownership or control in MPOWER that
                           terminates or substantially alters the stock option
                           plan, you will vest immediately in all outstanding
                           shares of this initial options grant.

                           to and from Denver/Albuquerque until a final decision

                           schedule, according to the stock option plan, 25% of

                           the total options grant according to the terms of the
                           final, approved plan. Should there be a change of

                           final, approved plan. Under this plan, you are
                           eligible to receive a minimum of 50,000 stock

facilities to and for the Premises which the Landlord is required to provide

the Premises, or any part thereof, from any cause whatsoever, including, without
limitation, the negligence of Sublessor or the Landlord, or any of their
respective agents, employees, contractors, or guests, or the negligence of any
other party leasing, occupying, or otherwise using any part of the Building.
Sublessee shall indemnify and hold Sublessor harmless from and against any and
all claims asserted against Sublessor or the Landlord arising from any such
damages, injuries, or losses incurred by Sublessee or any of its agents,

Sublessee agrees that it shall be solely responsible for obtaining and
installing, at its own expense, a phone system for the Premises. The

on a fair and equitable basis to be allocable to the Tower; including, without
limitation, costs incurred in connection with cleaning the Common Areas within
the Improved Area; property and general liability insurance coverages covering.

territorial boundaries include the Improved Area) which are not fairly allocable
to the Parking Garage, the Retail Area, or any other rentable components of the

paid by Landlord to any other tenant or third party; interest, depreciation, or
expenditures of a capital nature, except to the extent that such expenditures
are required due to a change in law after the Lease Commencement Date, or are
incurred to cause a reduction in any item of Operating Costs, in which case such
capital expenditures shall be amortized in accordance with generally accepted
accounting principles applied on a consistent basis (but in no event shall any
costs for any device or system installed to reduce any item of Operating Costs
exceed the amount of any savings actually achieved by such device or system);
and all costs incurred by Landlord in making any alterations to the Building
pursuant to the laws and regulations commonly known as the Americans with
Disabilities Act. Also, if Landlord constructs any other buildings for lease
within the boundaries of the Improved Area, Operating Costs, exclusive of those
incurred directly for the Building, shall be reasonably allocated by Landlord on
a fair and equitable basis between the Building hereunder and such other
buildings. The determination of Operating Costs and their allocation and
amortization shall be in accordance with generally accepted accounting
principles applied on a consistent basis.

                (3)     If the Building and other buildings located on the
Improved Area are not fully rented during all or a portion of any calendar year,
Landlord shall make an appropriate adjustment of the Operating Costs which vary
with occupancy for such year, employing sound accounting and management
principles, to determine the amount of Operating Costs payable by Tenant
hereunder had all such buildings been fully rented.

                (4)     Operating Costs shall not reflect any type or degree of
service or duty performed by or through Landlord for any other tenant which is
not required to be performed for Tenant under this Lease which results in a cost
this Lease.

                (5)     During December of each calendar year or as soon
thereafter as practicable, Landlord shall give Tenant written notice of
Landlord's estimate of Tenant's Pro Rata Share of Operating Costs in excess of
Base Operating Costs payable hereunder for the ensuing calendar year. On or
before the first day of each month during the ensuing calendar year, Tenant
shall pay to Landlord one twelfth (1/12) of such estimated amount, provided that
if such notice is not given in December, Tenant shall continue to pay on the
basis of the prior year's estimate until the month after such notice is given.
If at any time it appears to Landlord that Tenant's Pro Rata Share of Operating
Costs payable hereunder for the current calendar year will vary from its
estimate by more than twenty percent (20%), Landlord may, by written notice to
Tenant, revise its estimate for such year, and subsequent payments by Tenant for
such year shall be based upon such revised estimate.

                (6)     Within ninety (90) days after the close of each calendar
year, or as soon thereafter as practicable, Landlord shall deliver to Tenant a
statement



                                      -10-

<PAGE>   33
of additional Rent for Operating Costs payable hereunder for such calendar year.
If such statement shows an amount owing by Tenant that is less than the
estimated payments for such calendar year previously made by Tenant, Landlord
shall credit the excess to the next succeeding monthly installment or
installments of Rent, or, if no additional Rent is payable hereunder by Tenant
at the time that such determination is made, Landlord shall pay such amounts to
Tenant. If such statement shows an amount owing by Tenant that is more than the
estimated payments for such calendar year previously made by Tenant, Tenant
shall pay the deficiency to Landlord within thirty (30) days after delivery of
such statement.

                (7)     If, for any reason other than the default of Tenant,
this Lease shall terminate on a day other than the last day of a calendar year,
the additional Rent for Operating Costs payable by Tenant applicable to the
calendar year in which such termination shall occur shall be prorated on the
basis which the number of days from the commencement of such calendar year to
and including such date of termination bears to three hundred sixty-five (365).

                (8)     Landlord shall, upon Tenant's written request, deliver
to Tenant a written accounting showing how Operating Costs were calculated for
any year (the "Statement"). In the event Tenant objects to the Statement of
Operating Costs for any year, Tenant and Landlord agree to cooperate in good
faith to resolve any such objection. The foregoing notwithstanding, Tenant shall
in no way be relieved of its obligation to pay Tenant's Pro Rata Share of
Operating Costs in excess of the Base Operating Costs as calculated by Landlord
until such objection is resolved. If Landlord and Tenant are unable to resolve
such objection within thirty (30) days after Tenant's notice of objection was
given, Tenant shall have the right of access to all of Landlord's books and
records relating to the Operating Costs and may cause a review thereof to be
performed by an independent accountant for the period covered by the Statement
(the "Tenant's Audit"). After the completion of the Tenant's Audit, the
individual who prepared the Statement and the individual who prepared the
Tenant's Audit shall use reasonable good faith efforts to agree on any item in
dispute between the Statement and the Tenant's Audit and any items as to which
agreement is reached shall be resolved by such agreement. If the two individuals
fail to agree as to any items in dispute within twenty (20) days after the
completion of the Tenant's Audit, then the two individuals shall appoint an
independent certified public accountant (the "Third Accountant")-and shall
deliver copies of the Statement and the Tenant's Audit to such Third Accountant,
specifying the individual items still in dispute. The Third Accountant shall
resolve each item in dispute in an amount not higher than that determined by the
higher audit and not lower than that determined by the lower audit as determined
by the Third Accountant's review of the Statement, the Tenant's Audit, and such
further inquiries and investigations as the Third Accountant determines to make.
The Third Accountant shall make his decision as to each item in dispute and give
written notice of his decision to Landlord and Tenant within fifteen (15) days
after this appointment. The determination made as to any



                                      -11-
<PAGE>   34

items in accordance with the foregoing procedures shall be final and binding on,
both Landlord and Tenant as to such items. Any adjustment required to be made to
any previous payment made by Tenant by reason of such decision shall be made by
Tenant or Landlord within fourteen (14) days after notice of the final decision
has been given to Landlord and Tenant. The party required to make payment under
such adjustment shall bear all costs of the Tenant's Audit and the Third
Accountant, unless such payment is less than $20,000.00, in which case Tenant
shall bear all such costs.

                                  4. UTILITIES

        Landlord shall provide to the Leased Premises the following utility
services: hot and cold running water, sewer, natural gas, and electric power in
an amount not less than an average of 6.0 watts per rentable square foot in the
Leased Premises. Electrical usage by Tenant shall be determined on an average
hourly basis by readings made in hourly increments during normal business hours
and such usage shall be calculated and determined on an annualized basis.
Utility charges for which separate billings are not available shall be treated
as Operating Costs. If Landlord shall from time to time reasonably determine
that the use of electricity or any other utility or service in the Leased
Premises is disproportionate to the use of other tenants, Landlord may require a
separate meter to be installed at Tenant's expense in the Leased Premises to
monitor the use of any such utility or service and Tenant shall pay the amount
of all charges for the separately metered use of such utility or service;
provided that in no event shall any electrical usage by Tenant which does not
exceed the 6.0 watts per square foot standard set forth above in this Paragraph
4 be considered disproportionate hereunder. To the extent that, during any year,
Tenant pays the charges incurred for its usage of any separately metered utility
or service directly to either Landlord or the provider of such service, based on
such separate metering for such utility or service, the Operating Costs shall be
adjusted in a fail' and equitable manner (as determined by Landlord in its
reasonable discretion) so that the Operating Costs payable by Tenant shall not
include costs attributable to providing to other rentable components in the
Improved Area the utilities or services which are separately metered and paid
for by Tenant.

Landlord at least 24 hours prior notice that Tenant requires heating,
ventilation, or cooling of the Leased Premises at any other time, Landlord shall
provide the same at Landlord's actual cost therefor, which cost is currently
$25.00 per hour; provided further that, if Tenant does not give Landlord 24
hours prior notice of any such request, Landlord shall use reasonable efforts to
provide the same to Tenant at the times requested by Tenant, but Tenant shall
pay any additional charge reflecting the increased actual cost to Landlord in
providing such service at such times, which charge shall be disclosed to Tenant
when it orders such service.

                (2)     Janitorial services, including window washing, as
reasonably required to keep the Leased Premises in a clean and wholesome
condition and meeting the specifications set forth on Exhibit D attached hereto

at least equal to an average of 6.0 watts per square foot in the Leased Premises
in accordance with the terms Set forth in Paragraph 4 hereof; provided that,
lighting to the Premises outside of the normal Building Hours shall be subject
to a charge to Tenant in an amount not to exceed Landlord's reasonable good
faith estimate of the actual out-of-pocket costs incurred by Landlord in
providing such lighting (which amount is currently $5.00 per floor per hour)and
shall be provided to the Premises at any time on a 24-hour basis upon request by
Tenant, or any of Tenant's employees, and Landlord shall maintain a procedure by

Building, the Common Areas, and all other portions of the Improved Area, and for
the provision of Landlord's services under this Lease, and shall be responsible
for and shall expeditiously maintain and repair the foundations, structure, and
roof of the Building, and repair damage to the Building, and shall be
responsible for the compliance of the Building (including the core and shell

improved Area and with all applicable federal, state, and local laws, rules,
codes, and other regulations, including, without limitation, all building and
zoning codes and regulations, all environmental laws and regulations, and the
Americans with Disabilities Act.

        C.      Landlord shall not be liable to Tenant, nor shall Rent be
abated, due to any interruption of the services which Landlord is required to
provide under Paragraph 4 above or this Paragraph 5 resulting from any cause or
event which is beyond the reasonable control of Landlord; provided that, if any
such interruption of services causes the Leased Premises (or any part thereof)
to be untenantable for a period of five (5) business days, Rent shall be abated
proportionately'.

                        6. INDEMNIFICATION AND INSURANCE

        A.      Landlord shall not be liable to Tenant, and Tenant hereby waives
all claims against Landlord for any injury to or death of any person or damage
to any property (i) occurring in, on, or about the Leased Premises by or from
any cause



                                      -14-

<PAGE>   37

whatsoever, whether or not such injury, death, or damage may be caused in part
by the passive negligence or fault of Landlord, its employees, agents, or
contractors, and excepting in all cases any such injury, death, or damage to the
extent caused by the sole or active negligence or willful misconduct of
Landlord, its employees, agents, or contractors, or (ii) occurring in, on, or
about the Improved Area by reason of any act or omission or any active, passive,
or concurrent negligence or fault of Tenant.

        B.      In addition to Tenant's obligations under Paragraphs 6D and 6F
below, except to the extent covered by any policies of insurance maintained, or
required hereby to be maintained, by Landlord (which policies shall, pursuant
to Paragraph 6F(iii) below, be secondary to the insurance coverages carried by
Tenant), Tenant agrees to indemnify, protect, and hold harmless Landlord, from
and against any and all claims or liability for any injury to or death of any
person (including employees of Tenant and Landlord) or damage to any property
(including property belonging to Tenant and Landlord) whatsoever (i) occurring
in, on, or about the Leased Premises; or any part thereof, from any cause
whatsoever, whether or not such injury, death, or damage may be caused in part
by the passive negligence or fault of Landlord, its employees, agents, or
contractors, and excepting in all cases any such injury, death, or damage to the
extent caused by the sole or active negligence or willful misconduct of
Landlord, its employees, agents, or contractors, or (ii) occurring in, on, or
about the Improved Area by reason of any act or omission or any active, passive,
or concurrent negligence or fault of Tenant. The obligations of Tenant set forth
in this Paragraph 6B shall survive termination of this Lease by expiration of
the Lease Term or otherwise for a period of one year.

        C.      Tenant shall, at its sole cost and expense, obtain and keep in
force during the Lease Term, fire and extended coverage insurance on Tenant's
improvements; fixtures, furnishings, and equipment in and upon the Leased
Premises or Building in an amount not less than one hundred percent (100%) of
the full replacement cost (without deduction for depreciation) thereof. All
amounts received from said insurance for any damage to or destruction of any of
the improvements in the Leased Premises shall be applied to the payment of the
cost of repair or replacement of such improvements (and the balance shall be
retained by Tenant), unless this Lease terminates prior to such repair or
replacement being made, in which case the portion of such amounts representing
damage to any such improvements which would have become Landlord's property
pursuant to Paragraph 10 hereof shall be paid over to Landlord, and the balance
shall be retained by Tenant.

        D.      Without in any way limiting Tenant's liability pursuant to
Paragraph 6B above, Tenant shall, at its sole cost and expense, obtain and keep
in force during the term of this Lease comprehensive general liability insurance
(bodily injury and property damage) with a limit of liability not less than one
million dollars ($1,000,000) per occurrence and with the following supplementary
coverages: (a) personal injury liability with the "employee" and "contractual"
exclusions deleted;



                                      -15-

<PAGE>   38

and (b) broad form property damage liability. Landlord shall have the right, at
any time or from time to time, upon reasonable prior written notice to Tenant,
to require Tenant to make reasonable adjustments to the amount of insurance
required hereunder to reflect increases in the Consumer Price Index as published
by the U.S. Department of Commerce, and/or to modify its form.

        E.      During the Lease Term, Landlord shall insure the Building,
excluding any property which Tenant is obligated to insure, against damage by
fire and standard extended coverage perils and Landlord shall maintain
comprehensive general liability insurance in such amounts and with such
deductibles as are from time to time generally accepted as commercially
reasonable for first class office buildings in the Denver metropolitan area;
provided, however, that Landlord shall have the tight, at its election, to
maintain all or any part of such insurance under the Chevron Self-Administered
Claims Adjustment Program described in Exhibit L attached hereto. Landlord may,
but shall not be obligated to, takeout and carry any other form or forms of
insurance as it or Landlord's mortgagees may reasonably determine advisable.
Notwithstanding any contribution by, Tenant to the cost of insurance premiums,
as provided herein, Tenant acknowledges that it has no right to receive any
proceeds from any such insurance policies carried by, Landlord. Landlord will
not have to carry insurance of any kind on Tenant's furniture or furnishings, or
on any of Tenant's fixtures, equipment, improvements, or appurtenances under
this Lease.

        F.      All insurance required under this Paragraph 6 and all renewals
thereof shall be issued by such responsible companies qualified to do and doing
business in the State of Colorado as may be approved by Landlord. Each policy
required hereunder to be carried by Tenant (i) shall expressly provide' that the
policy shall not be cancelled or materially altered without thirty (30) days'
prior written notice to Landlord, (ii) shall name Landlord as an additional
insured, (iii) shall be primary and noncontributing with any insurance which may
be carried by Landlord, and (iv)shall expressly provide that Landlord, although
named as an additional insured, shall nevertheless be entitled to recover
against Tenant under the policy for any loss; injury or damage to Landlord, its
employees and contractors, and shall contain a standard "cross liability" or
"severability of interest" clause.

Upon the issuance thereof, Tenant shall cause a certificate of the insurance
coverages maintained by Tenant hereunder to be delivered to Landlord.

                            7. WAIVER OF SUBROGATION

        Tenant hereby waives, for itself and on behalf of its insurers under all
policies of fire, theft, public liability, workers' compensation, and other
insurance now or hereafter existing during the Lease Term and purchased by or
for Tenant insuring or covering the Leased Premises, or any portion or any
contents thereof, or any

operations therein, or the Building, all rights of subrogation which any insurer
might otherwise have to any claims of Tenant against Landlord. Landlord hereby
waives, for itself and on behalf of its insurers under all policies of fire,
theft, public liability, workers' compensation, and other insurance now or
hereafter existing during the Lease Term and purchased by or for Landlord
insuring or covering the Improved Area or the Building or any portion or the
contents thereof, or any operations therein, all rights of subrogation which any
insurer might otherwise have to any claims of Landlord against Tenant. Landlord
and Tenant shall each, prior to or immediately after the execution of this
Lease, procure from each of such insurers a waiver of all rights of subrogation
which the insurer might otherwise have as against the other. This Paragraph 7
shall not be construed to require Landlord or Tenant to obtain any insurance
coverage not otherwise required by this Lease nor to waive any rights of
recovery that either Landlord or Tenant may have directly against the other to
the extent that any loss or damage giving rise to any such right of recovery is
not actually covered by insurance.

                                   8. REPAIRS

        Except for services provided by Landlord, Tenant shall maintain in a
clean, orderly, and sanitary condition and keep in good repair, the interior of
the Leased Premises, ordinary wear and tear and damage by fire or other casualty
excepted. Such maintenance and repair shall be at the sole cost of Tenant and
shall include but not be limited to the maintenance and repair of floor
covering, ceilings, and walls, front and rear doors, and all interior glass on
the Leased Premises. If Tenant fails to maintain or keep the Leased Premises in
good repair and such failure continues for thirty (30) days after written notice
from Landlord, Landlord may perform any such required maintenance and repairs
and the cost thereof shall be additional Rent payable by Tenant within ten (10)
days of receipt of any invoice therefor from Landlord.

                              9. TENANT'S PROPERTY

        All furnishings, trade fixtures, and moveable equipment, including,
without limitation, the secretarial work stations installed in the Leased
Premises by Tenant, paid for and installed by Tenant, shall be the property of
Tenant. Upon expiration of this Lease, Tenant may remove any such property and
shall remove any such property if directed by Landlord. Tenant shall repair, or
reimburse Landlord for the cost of repairing, any damage resulting from removal
of Tenant's property. If Tenant fails to remove such property as required under
this Lease, Tenant shall be deemed to have abandoned all interest in any such
property remaining or then in or upon the Leased Premises and Landlord may
remove the same as its own property and dispose of such property as it desires
without liability to Tenant.

                   10. IMPROVEMENTS AND ALTERATIONS BY TENANT

        Tenant may make such additional improvements or alterations to the
Leased Premises as it deems necessary or desirable, but only with Landlord's
prior written approval (which approval shall not be unreasonably withheld). Any
such improvements or alterations by Tenant shall be at Tenant's expense and
shall be done by a licensed contractor approved by Landlord in conformity with
plans and specifications approved by Landlord, which approvals shall not be
unreasonably withheld. If requested by, Landlord, Tenant will post a bond or
provide other security reasonably satisfactory to Landlord to protect Landlord
against liens arising from work performed for Tenant. All work performed shall
be done in a good and workmanlike manner, in accordance with applicable law, and
with materials (where not specifically described in the specifications) of the
quality and appearance comparable to those in the Building. Prior to the
commencement of any work or delivery of any materials to the Leased Premises,
Tenant shall furnish Landlord, for its approval (which approval shall not be
unreasonably withheld), copies of the following:

                (a)     Plans and specifications,

                (b)     Names and addresses of contractors,

                (c)     Copies of contracts, and

                (d)     Necessary permits.

        Unless otherwise agreed in writing between the parties at the time of
Landlord's approval of any alterations, all alterations, fixtures (except trade
fixtures, including the secretarial workstations installed in the Leased
Premises by Tenant) and improvements, including those made or installed in or
upon the Leased Premises by or for Tenant, shall immediately become Landlord's
property and, at the end of the Lease Term, shall remain on the Leased Premises
without compensation to Tenant.

                                  11. CASUALTY

        If the Leased Premises or the Building are destroyed or damaged by
fire, earthquake, or other casualty to the extent that the Leased Premises are
untenantable in whole or in part, then Landlord shall, except as provided
below, proceed with reasonable diligence to rebuild and restore the Leased
Premises or such part thereof as may be destroyed or damaged, and during the
period of such rebuilding and restoration, this Lease shall remain in full force
and effect, and Rent shall be abated in the same ratio as the square footage in
the portion of the Leased Premises rendered untenantable, if any, shall bear to
the total square footage in the Leased Premises.



                                      -18-

<PAGE>   41

If Landlord shall reasonably determine that such destruction or damage cannot be
rebuilt and restored within one-hundred-eighty (180) days of the occurrence, it
shall so notify Tenant within sixty (60) days after the occurrence of such
damage or destruction. In such event, either Landlord or Tenant may, within
twenty (20) days after such notice, terminate this Lease as of the date of such
casualty. If neither party terminates this Lease during such twenty (20) day
period, this Lease shall remain in effect and Landlord shall diligently proceed
to rebuild and restore the Leased Premises, and Rent shall abate as set forth
above. Anything in this Lease to the contrary notwithstanding, in the event the
Leased Premises are rendered untenantable due to the fault or neglect of Tenant,
its agents, employees, invitees, or licensees, there shall be no abatement of
Rent under this Paragraph 11.

                     12. ASSIGNMENT, LETTING AND SUBLETTING

        A.      Tenant, its legal representatives and successors in interest,
shall have no right to assign, let, or sublet or permit assigning, letting or
subletting of this Lease, the Leased Premises or any part thereof, respectively,
without first obtaining the written consent of Landlord, which consent shall not
be unreasonably withheld; provided that Tenant shall have the right, without
obtaining Landlord's prior consent, to sublease or assign this Lease, or all or
any portion of the Leased Premises, at any time and from time to time to any
entity which controls, is controlled by, or is under common control with Tenant,
or any successor to Tenant by merger, consolidation, or reorganization, or any
person or entity which purchases all or any substantial portion of the assets of
Tenant (which entities are referred to herein collectively as the "Tenant
Affiliates"). Any consent of Landlord required hereby, unless specifically
stated therein, shall not relieve Tenant from its obligations under this Lease,
and a consent by Landlord to any one assignment or subletting shall not
constitute a consent to any other or subsequent assignment or subletting.

        B.      In addition to any other reasonable basis, Landlord shall be
deemed to be acting reasonably in withholding its consent to any such assignment
or subletting, if such assignment or subletting would result in the assignment,
leasing or subleasing of the Leased Premises to any person or entity:

                (1)     who proposes to conduct a business therein which is not
in conformance with the provisions of Paragraph 2 hereof; or

                (2)     whose business is of a character which is not, in
Landlord's reasonable opinion, consistent with the character of the Building.



                                      -19-

<PAGE>   42

        C.      Tenant shall provide Landlord with a copy of any assignment of
this Lease or any sublease of the Leased Premises and a copy of any document
pursuant to which any such assignment or sublease may be made. Except in the
event of any assignment or sublease to or with any Tenant Affiliate, Tenant
shall pay or deliver over to Landlord, as additional Rent hereunder, an amount
equal to one-half of any consideration received by Tenant in respect of any
such assignment or sublease (after deduction for all reasonable costs and
expenses incurred by Tenant in connection with such assignment or subletting,
including, without limitation, leasing commissions, tenant improvement costs,
marketing costs, lease takeover obligations, rent concessions and other
concessions or incentives, and all similar costs, and all Rent accruing
hereunder during the period of time that Tenant is marketing the Leased Premises
for such assignment or subletting) in excess of the Rent due under this Lease
attributable to such portion of the Leased Premises covered by such or
sublease.

                            13. LIENS AND INSOLVENCY

        Tenant shall keep the Leased Premises, the Building, and the improved
Area free from any liens arising out of any work performed, materials furnished,
or obligations incurred by Tenant.

                                14. CONDEMNATION

        If all or any part of the Leased Premises are taken under power of
eminent domain or like power, or sold under imminent threat thereof to any
public authority or private entity having such power, this Lease shall terminate
as to the part of the Leased Premises so taken or sold, effective as of the date
possession is required to be delivered to such authority or entity. Rent for the
remaining Lease Term shall be reduced in the proportion that the Tenant's Total
Square Footage is reduced by the taking. If a partial taking or sale of the
Building or the Leased Premises (i) substantially reduces the area of the Leased
Premises resulting in a substantial inability of Tenant to use the Leased
Premises for Tenant's business purposes, or (ii) renders the Building unviable
to Landlord, Tenant, in the case of (i), or Landlord, in the case of (ii), may
terminate this Lease by written notice delivered to the other party within
thirty (30) days after the terminating party receives notice of the portion to
be taken or sold, such termination to be effective one-hundred-eighty (180) days
thereafter, or when the portion, is taken or sold, whichever is sooner. All
condemnation awards and similar payments shall be paid and belong to Landlord,
except any amounts awarded or paid specifically for Tenant's furnishings, trade
fixtures, and other personal property, the value of Tenant's leasehold interest
in the Building hereunder, any loss of business and business interruption costs,
and all relocation costs; provided that in no event shall any such awards to
Tenant be



                                     - 20 -

<PAGE>   43

permitted to have the effect of reducing Landlord"s award. Nothing contained
herein shall diminish Tenant's right to deal on its own behalf with the
condemning authority.

                           15. CONSTRUCTION CONDITIONS

        A.      Tenant shall construct the Leasehold Improvements to the Leased
Premises pursuant to the Work Agreement (Exhibit C).

        B.      To the extent that any term or provision of this Lease conflicts
with the Work Agreement, the Work Agreement shall control.

                     16. OCCUPANCY, LEASE COMMENCEMENT DATE

        As used, herein, the "Lease Commencement Date" shall mean the later of
(i) the Scheduled Commencement Date, or (ii) that date Which is determined by
adding to the Scheduled Commencement Date the number of days that Substantial
Completion of the Leasehold Improvements is delayed due solely to a Landlord
Delay (as defined in the Work Agreement) or due to any other cause which is in
the nature of an Unavoidable Delay as defined in Paragraph 23C. If the Lease
Commencement Date has not occurred on or before one hundred and twenty (120)
days following the Scheduled Commencement Date, Tenant shall have the right to
terminate this Lease by written notice given to Landlord at any time prior to
Substantial Completion of the Leasehold Improvements. Prior to occupying the
Leased Premises, Landlord and Tenant shall execute and deliver a letter in the
form attached hereto as Exhibit E, acknowledging the Lease Commencement Date. If
either Landlord or Tenant fails to deliver such letter, the date of Substantial
Completion of the Leased Premises shall be deemed to be the Scheduled
Commencement Date.

        If Tenant commences the regular conduct of its business in any part of
the Leased Premises prior to Lease Commencement Date, Tenant shall pay to
Landlord rent for each day prior to the Lease Commencement Date, calculated on
the basis of the per diem Rent which would be due to Landlord from Tenant if the
Lease Term had commenced for the portion of the Leased Premises occupied by
Tenant for such purpose.

                            17. RULES AND REGULATIONS

        Tenant covenants that Tenant and its agents, employees, invitees, or
those claiming under Tenant, will at all times observe, perform, and abide by
all reasonable rules and regulations promulgated by Landlord, from time to time
upon receipt of written notice thereof, as long as such rules and regulations do
not conflict



                                      - 21-
<PAGE>   44

with, or unreasonably modify, any provision of this Lease and are generally
applicable to all tenants in the Building. Landlord's rules and regulations in
effect on the date hereof are attached hereto as Exhibit F. All such rules and
regulations shall be interpreted and enforced by Landlord in a consistent manner
as to Tenant and all other tenants in the Building.

                                   18. PARKING

        Landlord shall provide to Tenant non-exclusive parking within the
Parking Garage contiguous to the Building at a ratio of one space for each 330
rentable square feet contained from time to time within the Leased Premises
(including any additional space taken by Tenant pursuant to Paragraph 45 or
Paragraph 46 hereof) (the "Regular Spaces"), and an additional 81 short-term
parking spaces in close proximity to the elevators, which shall be available for
use by Tenant's visitors at no cost for up to two hours. The Regular Spaces
(which, as of the Commencement Date, shall be 168 spaces) will be provided by
Landlord for use by the Tenant at a charge of _________ per space per month
during the first sixty (60) months Of the Lease Term and _________ per space per
month during months 61 through 120. Subject to Landlord's rules and regulations
adopted from time to time pursuant to Paragraph 17, Tenant's employees, invitees
and licensees shall be entitled to reasonable use of such parking spaces.

                                   19. ACCESS

        Landlord, or Landlord's employees, agents, or contractors; may enter the
Leased Premises at reasonable times for the purpose of inspecting, altering or
repairing the Leased Premises or other portions of the Building and for the
purpose of ascertaining compliance by Tenant with the provisions of this Lease.
Landlord may also show the Leased Premises to prospective purchasers or lenders
(or, during the last B months of the Lease Term, to prospective renters) during
regular business hours and upon reasonable prior notice. Landlord's entry shall
not unreasonably interfere with Tenant's business operations or with Tenant's
use and occupancy of the Leased Premises. Landlord shall repair, at Landlord's
expense, any damage to the Leased Premises resulting from the exercise of the
foregoing rights by Landlord or Landlord's employees, agents, or contractors.

                                    20. SIGNS

        All signs and symbols placed on the doors or windows or elsewhere about
the Leased Premises, or upon any other part of the Building, including building
directories, shall be subject to the approval of Landlord, which approval shall
not be



                                     - 22 -
<PAGE>   45
unreasonably withheld. Tenant shall have no right to place signs outside the
Building and within the Improved Area. Tenant shall be entitled to place signs
within the interior of the Leased Premises without having first obtained
Landlord's approval. Upon expiration of this Lease, all signs installed by
Tenant shall be removed and any damage resulting therefrom shall be promptly
repaired, or such removal and repair may be done by Landlord and the cost
thereof charged to Tenant as additional Rent hereunder. Landlord shall, at
Landlord's expense, provide space to Tenant for 16 names on the main directory
board located in the lobby of the Building, which names may be designated from
time to time by Tenant. Additionally, Landlord shall include Tenant's company
name on the group and alphabetical listings on such directory board.

                              21. TENANT'S DEFAULT

        It shall be an "Event of Default" if (i) Tenant fails to pay Rent or any
other charge or payment required of Tenant hereunder when due and such failure
continues for ten (10) days after written notice thereof to Tenant by Landlord;
(ii) Tenant violates or fails to perform any of the other conditions, covenants,
or agreements herein made by Tenant, and such violation or failure continues for
fifteen (15) days after written notice thereof to Tenant by Landlord; (iii)
Tenant makes a general assignment for the benefit of its creditors or files a
petition for bankruptcy or other reorganization, liquidation, dissolution, or
similar relief; (iv) a proceeding is filed against Tenant seeking any relief
mentioned in (iii) above which is not dismissed within sixty (60) days after
Tenant receives notice of such proceeding; (v) a trustee, receiver, or
liquidator is appointed for Tenant or a substantial part of its property; (vi)
Tenant's interest under this Lease is taken upon execution or by other process
of law directed against Tenant or shall be made subject to any attachment by or
on behalf of any creditor of Tenant; or (viii) Tenant mortgages, assigns (except
as expressly permitted in this Lease) or otherwise encumbers Tenant's interest
under this Lease.

        If an Event of Default occurs, Landlord may: (i) without obligation to
do so and without releasing Tenant from any obligation under this Lease, make
any payment or take any action Landlord may deem necessary or desirable to cure
such Event of Default, and the cost thereof shall be reimbursed by Tenant to
Landlord within ten (10) days after demand; (ii) terminate this Lease by written
notice to Tenant as of the date such notice is given or as of any other date
specified in such notice; (iii) with or without terminating this Lease, reenter
and take possession of the Leased Premises by legal proceedings; (iv) with or
without terminating this Lease, if Tenant has abandoned the Leased Premises,
reenter and take possession of the Leased Premises, or any part thereof, end
remove the effects therein without liability for any damages thereto and without
being deemed guilty of any manner of trespass and without prejudice to any other
remedies of Landlord hereunder; and (iv) exercise any other legal remedy,
including, without limitation, any applicable equitable



                                     - 23 -
<PAGE>   46

remedies, on account of such Event of Default. All remedies of Landlord under
this Lease shall be cumulative, and the exercise of any of such remedies shall
not prevent the concurrent or subsequent exercise of any other remedy.

        Should Landlord elect to reenter or take possession of the Leased
Premises pursuant to legal proceedings or otherwise, Landlord shall, from time
to time, without terminating this Lease, use reasonable efforts to relet the
Leased Premises or any part thereof on behalf of Tenant for such term or terms
and at such rent or rents, and upon such other terms and conditions, as Landlord
may deem reasonably advisable (including, without limitation, giving any
concessions, free rent, and any other concessions which may be reasonably
necessary under the circumstances), with the right to make alterations and
repairs to the Leased Premises. No such reentry or taking of possession of the
Leased Premises by Landlord shall be construed as an election on Landlord's pact
to terminate this Lease, unless a written notice of termination is given to
Tenant by Landlord, nor shall it preclude landlord from terminating this Lease
at a later time by giving written notice to Tenant.

        If Landlord elects to take possession without terminating this Lease,
then such repossession shall not relieve Tenant of its obligations and
liabilities under this Lease, all of which shall survive such repossession. In
the event of such repossession, Tenant shall pay to Landlord, as rent, all Rent
which would be payable hereunder if such repossession had not occurred, less the
net proceeds, if any, of any reletting of the Leased Premises, after deducting
all of Landlord's reasonable expenses in connection with such reletting and any
reasonable rental concessions. Tenant shall pay such Rent to Landlord on the
days on which such Rent would have been payable hereunder if possession had not
been retaken.

        If, however, this Lease is terminated by Landlord, Landlord shall be
entitled to recover as damages from Tenant, in addition to all other damage
suffered by Landlord on account of any Event of Default, the sum of (i) the
present Value of all of the Rent which would have been due for the remainder of
the Lease Term had this Lease not been terminated, plus all of Landlord's costs
of reletting the Leased Premises, including repair, alteration, and preparation
of the Leased Premises for reletting, brokerage commissions, attorneys' fees,
and rental concessions. Said amount shall be immediately due and payable by
Tenant to Landlord, minus (ii) the present value of the fair rental value of the
Leased Premises from the effective date of such termination through the date on
which the Lease Term would have expired had the Lease not been terminated. Any
amount due to Landlord hereunder may be collected after termination. For
purposes of calculating present values under this Paragraph 21, the applicable
discount rate shall be equal to the sum of 2% plus the prime lending rate in
effect as of the date of the Event of Default as quoted in the Wall Street
Journal (the "WSJ"), or, if the WSJ ceases to be published, a similar national
daily business publication identified by Landlord.

        [Intentionally omitted].

                    23. QUIET ENJOYMENT; INABILITY TO PERFORM

        A.      If, and so long as, Tenant pays Rent and keeps and performs each
and every term, covenant, and condition herein contained on the part and on
behalf of Tenant to be kept and performed, Tenant shall quietly enjoy the Leased
Premises without hindrance or molestation by Landlord, subject to the terms,
covenants, and conditions of this Lease.

        B.      Landlord shall pay all Taxes so as not to jeopardize Tenant's
use or the Leased Premises. The foregoing notwithstanding, Landlord shall be
entitled to contest any tax or assessment which it deems to be improperly levied
against the Improved Area, or any part thereof, so long as Tenant's use of the
Leased Premises is not interfered with.

        C.      Except as otherwise provided in Paragraphs 4, 5, 11, and 16 of
this Lease, this Lease and the obligations of Tenant to pay Rent and perform all
of the terms, covenants, and conditions on the part of Tenant to be performed
shall in no way be affected, impaired, or excused because Landlord, due to an
Unavoidable Delay, is (a) unable to fulfill any of its obligations under this
Lease, or (b) unable to supply or is, delayed in supplying any service expressly
or impliedly to be supplied, or (c) unable to make or delayed in making any
repairs, replacements, additions, alterations, or decorations, or (d) unable to
supply or is delayed in supplying any equipment or fixtures. Landlord shall in
each instance exercise reasonable diligence to effect performance when and as
soon as possible. 'Unavoidable Delay' shall mean any and all delays beyond
Landlord's reasonable control, including without limitation, to the extent they
affect Landlord's ability to perform, delay caused by any Event of Default
hereunder by Tenant, governmental restrictions, governmental regulations or
controls, undue delays by governmental authorities, order of civil, military, or
naval authority, governmental preemption, strikes, labor disputes, lockouts,
shortage of labor or materials, inability to obtain materials or reasonable
substitutes therefor, default of any contractor or subcontractor, acts of God,
fire, earthquake, floods, explosions, extraordinary actions of the elements,
extreme weather conditions, enemy action, civil commotion, Hot, or insurrection,
delays in obtaining governmental permits or approvals for which Landlord has
made diligent, timely, and appropriate application, and any other cause beyond
Landlord's reasonable control.

                              24. HOLD OVER TENANCY

        If (without execution of a new lease or written extension) Tenant shall
hold over after the expiration of the Lease Term, Tenant shall be deemed to be
occupying the Leased Premises as a tenant from month to month, which tenancy may
be terminated as provided by law. During such tenancy, Tenant agrees to pay to
Landlord monthly installments of the Tenant's Pro Rata Share of Operating Costs
in excess of the Base Operating Costs and 150% of the then current Base Rent, as
set forth herein, unless a different rate is agreed upon, and to be bound by all
of the terms, covenants, and conditions as herein specified, so far as
applicable. The foregoing notwithstanding, in the event Landlord and Tenant are
negotiating in good faith over the extension of the Lease Term, Tenant, for a
period not to exceed sixty (60) days following the expiration of the Lease Term,
shall pay Rent at the same rate as was in effect immediately prior to such
expiration. At the and of such Sixty (60) day period, Tenant shall be deemed to
be occupying the Leased Premises as a tenant from month to month and Tenant
shall pay to Landlord, for such tenancy, monthly installments of the Tenant's
Pro Rata Share of Operating Costs in excess of the Base Operating Costs, all
other charges provided for in this Lease, and 200% of the then current Base Rent
until Tenant's occupancy is terminated.

                               25. ATTORNEYS' FEES

        In the event either party requires the services of any attorney in
connection with enforcing the terms of this Lease, or in the event suit is
brought for the recovery of any Rent due under this Lease, or for the breach of
any covenant or condition of this Lease, or for the restitution of the Leased
Premises to Landlord and/or eviction of Tenant during the Lease Term, or after
the expiration thereof, the party prevailing in any such legal action shall be
entitled to an award for all legal costs and expenses, including, but not
limited to, a reasonable sum for attorney's fees

                              28. AMENDMENT, WAIVER

        This Lease constitutes the entire agreement between the parties. This
Lease shall not be amended or modified except in writing by both parties. No
covenant or term of this Lease shall be waived except with the express written
consent of the waiving party whose forbearance or indulgence in any regard shall
not constitute a waiver of such covenant or term. Failure to exercise any right
in one or more instances shall not be construed as a waiver of the right to
strict performance or as an amendment to this Lease.

to any proposed mortgagee or purchaser, or to Landlord, together with a true and
correct copy of this Lease, certifying, if applicable, and making such changes

accord and satisfaction, notwithstanding any accompanying statement, instruction
or other assertion to the contrary (whether by notation on a check or in a
transmittal letter or otherwise), unless Landlord expressly agrees to an accord
and satisfaction in a separate writing duly executed by an authorized
representative of Landlord. Landlord may receive and retain, absolutely and for
itself, any and all payments so tendered, notwithstanding any accompanying
instructions by Tenant to the contrary. Landlord



                                     - 29 -

will be entitled to treat any such payments as being received on account of any
item or items or Rent, interest, expenses, or damage due in connection herewith

                                34. SEVERABILITY

        The parties intend this Lease to be legally valid and enforceable in
accordance with all of its terms to the fullest extent permitted by law. If any
term hereof shall be finally held to be invalid or unenforceable, the parties
agree that such term shall be stricken from this Lease, the same as if it never
had been contained herein. Such invalidity or unenforceability shall not extend
to or otherwise affect any other term of this Lease, and the unaffected terms
hereof shall remain in full force and effect to the fullest extent permitted by
law, the same as if such stricken term never had been contained herein.

instruments"). Landlord hereby represents and warrants to Tenant that there are
no Superior Instruments presently executed which include any portion of the

instruments unless and until the holders thereof execute a non-disturbance
agreement in form and substance similar to the Attornment and Nondisturbance
Agreement attached hereto as Exhibit G, or in any other form reasonably
acceptable to Tenant.

mortgagee, as the case may be, of an agreement substantially in the form of the

                            42. ESTOPPEL CERTIFICATE

                [Intentionally Omitted].

                               43. RIGHT TO RENEW

        A.      Tenant shall have the option to renew the Term of this lease for
two (2) successive periods of five (5) years each by notifying Landlord in
writing of Tenant's election to exercise its option at least twelve (12) months
prior to the expiration of the then current term or renewal term of this Lease.
Tenant may exercise such option provided there is not then any uncured default
by Tenant in the payment of any item of Rent hereunder and there is not then any
other material uncured default hereunder by Tenant. The Rent during each renewal
period shall be the then Fair Market Rental Value, as hereinafter defined, and
the lease shall be upon all other terms and provisions of this Lease.

        B.      As used in this Lease, the term Fair Market Rental Value
("FMRV") shall mean the rent calculated at the then prevailing rate on the same
terms and conditions for the renewal term set forth in this Lease for similar
space in comparable Class A office buildings in the Denver Tech Center/Greenwood
Plaza market areas. In making such determination, no allowance shall be made for
any of the following:

                (1)     Whether Landlord or Tenant paid the cost of providing
the existing improvements to the Premises.



                                     - 32 -

<PAGE>   55

                (2)     The quality of the furniture or trade fixtures which
belong to Tenant and which Tenant is entitled to remove at the end of the Term.

                (3)     The expense and inconvenience to Tenant that would be
involved if Tenant were recruited to relocate to other space.

                (4)     The expense that Landlord would be required to incur to
find new tenants for the Premises.

                (5)     The presence of Tenant in the Building.

                (6)     The fact that Tenant has a renewal option.

        C.      FMRV shall be declared initially by Landlord in writing to
Tenant not less than ten (10) months prior to the end of the Lease Term. Tenant
shall have forty-five (45) days from the date of Landlord's declaration in which
to dispute, in writing, Landlord's finding of FMRV and to provide to Landlord
its written determination of FMRV. Failing such timely notice of dispute,
Landlord's declared FMRV shall be deemed to be acceptable by both parties. If
Tenant gives Landlord timely notice in dispute of Landlord's determination of
FMRV, then Landlord and Tenant shall each designate a licensed commercial real
estate broker who shall together designate a third licensed commercial real
estate broker, all of whom shall be experienced in evaluating rental properties
of the type and in the area of the Building. Within twenty (20) days of Tenant's
notice to Landlord, the third broker shall deliver to Tenant and Landlord its
written decision of the appropriate FMRV; provided that such broker's decision
shall be to accept either the FMRV determined by Landlord or the FMRV determined
by Tenant and such broker may not select an average of such determinations or
any other amount for the FMRV. Such determination shall be binding upon Landlord
and Tenant; provided that Tenant may, by written notice given to Landlord within
ten (10) days after Tenant's receipt of written notice of such broker's
determination of FMRV, revoke its notice to renew. All costs for the services of
the brokers selected by Landlord and Tenant and all costs for the services of
the third broker shall be paid by the party whose determination of FMRV was not
selected by the third broker as its FMRV.

                             44. RIGHT TO TERMINATE

Effective at any time and from time to time after the expiration of the sixtieth
(60th) month of the Lease Term, Tenant may elect to terminate this Lease as to
all or any portion of the Leased Premises which includes no less than all of
the space occupied by Tenant on any single floor of the Tower, provided there is
not then any uncured default by Tenant in the payment of any item of Rent
hereunder and there is not then any other material uncured default hereunder by
Tenant. In order to



                                     - 33 -

<PAGE>   56

exercise such option, Tenant shall give Landlord not less than six (6) months
prior written notice of its intent to terminate as of the date specified in such
notice (which date shall not be prior to the last day of the sixtieth month of
the Lease Term) (the "Termination Date"). Such notice shall identify the
portions of the Leased Premises which will be affected by such termination.
Tenant shall pay to Landlord, as of the Termination Date, and as to the portion
of the Leased Premises affected by any, such termination, the sum of (i) the
unamortized portion of the Improvement Allowance paid by Landlord to Tenant in
accordance with Exhibit C, (ii) the unamortized portion of the Moving Allowance
paid by Landlord to Tenant in accordance with Exhibit C, (iii) the unamortized
portion of the Space Planning Allowance paid by Landlord to Tenant in accordance
with Exhibit C, (iv) the unamortized portion of the commissions paid by Landlord
to the Landlord's Broker and the Tenant's Broker, and (v) three month's Base
Rent for the portion of the Leased Promises affected by any such, termination.
As used herein, unamortized costs shall mean the amounts applicable to any
period of time after the Termination Date for the relevant costs if the entire
costs thereof were amortized on a straight line basis over the entire ten (10)
year initial Lease Term.

                           45. RIGHT OF FIRST REFUSAL

        During the Lease Term, or any extension thereof, Tenant shall have a
right of first refusal on all of the remaining space on the ninth floor of the
Tower as and when such space, or any part thereof, becomes available to Landlord
(which space is hereinafter referred to as the 'Expansion Space').

        Each time Landlord receives from or is going to give a bona fide offer
to an actual third party ("Third Party Offer"), to lease part or all of the
Expansion Space, and such Expansion Space is then available, and such offer is
acceptable to Landlord, Landlord shall first offer such Expansion Space to
Tenant in writing ("Landlord's Notice") on the same Business Terms as were
offered to or by the third party. Expansion Space shall be considered
"available" when it becomes vacant after the termination or expiration of the
current lease of such space between Landlord and Telemedia North American
Communications. 'Business Terms' are hereby defined as: effective base rental
rate (base rental rate with any rent concession factored in); operating cost
stop; tenant improvement allowance; the number of rentable square feet contained
in such Expansion Space; and any other material economic terms. Tenant shall
have 10 business days after receipt of Landlord's Notice to accept Landlord's
offer in writing. If Tenant does not elect to accept Landlord's offer or fails
to respond within the 10 business day period, landlord shall be free to lease
the Expansion Space to the third party on terms that are not materially more
favorable to the third party than the Business Terms that were contained in the
third party's bone fide offer. If Tenant accepts the offer to lease such
Expansion Space, such Expansion



                                     - 34 -

<PAGE>   57

Space shall be leased by Tenant on the Business Terms offered to or by the third
party.

                            46. RIGHTS OF FIRST OFFER

        A.      Tenant shall have the right to lease any and all space on the
second through ninth floors of the Tower from time to time as and when portions
of such space become available to Landlord (which space is hereinafter referred
to as the "Offer Space"). As to any of the Offer Space which is now subject to
either an existing lease or any prior rights to lease, such Offer Space shall be
deemed to become available when such lease or such prior rights expire. Upon
the expiration of such lease or such rights, Landlord shall give written notice
thereof to Tenant (the "Offer Notice"), which notice shall set out the FMRV
which Landlord would at that time offer to other possible tenants of the Offer
Space.

        B.      Tenant shall have the right to lease such portions of the Offer
Space only if:

                (1)     Tenant delivers to Landlord written notice exercising
its option to lease the Offer Space within thirty (30) days after Tenant's
receipt of the Offer Notice for such Offer Space; and

                (2)     There is not any uncured default by Tenant in the
payment of any item of Rent hereunder and there is no other material uncured
default by Tenant hereunder at the time Landlord gives the Offer Notice or at
the commencement of the lease of Offer Space.

        If Tenant fails to timely exercise its right to lease any portion of the
Offer Space after Tenant's receipt of the Offer Notice from Landlord for such
Offer Space, Tenant shall have no further right to lease that Offer Space under
this Paragraph 46.

        C.      The following terms shall apply to and govern each lease of any
portion of the Offer Space which Tenant elects to lease under this Paragraph 46:

                (1)     Base Rent shall be equal to the FMRV as determined in
accordance with the terms set forth in Paragraph 43 of this Lease based upon the
terms and conditions applicable to Tenant's lease of such Offer Space as set
forth in this Paragraph 46 and the Base Year Operating Costs for such Offer
Space shall be the Operating Costs for the year on which the lease for such
Offer Space commences hereunder.

                (2)     The term shall begin on the date the Offer Space becomes
available to Landlord for releasing and end on the expiration or earlier
termination of



                                     - 35 -

<PAGE>   58

the Lease Term, including any and all extensions thereof; provided that Rent for
such Offer Space shall not be payable until the 60th day after the beginning of
the term for such Offer Space.

                (3)     Tenant shall take the space in an "As is" condition with
all improvements to be Tenant's responsibility at Tenant's cost.

        D.      Landlord and Tenant shall execute those instruments Landlord
reasonably requests to evidence the inclusion of arty Offer Space leased by
Tenant under this Paragraph 46 into the balance of the Leased Premises then
leased by Tenant under this Lease.

        IN WITNESS WHEREOF, Landlord and Tenant have executed this Lease as of
the day and year first hereinabove written.

                                 PLAZA TOWER ONE

                              Contractor Procedures

GENERAL INFORMATION

Plaza Tower One is a facility which is very customer focused. We pride in our
continued effort to please our clients and keep their best interests in mind. As
we all know, construction can be a very intrusive process and it takes great
patience and preplanning to anticipate it's effect on the existing tenant base.
To that end, procedures have been established to ensure the necessary steps are
in place to anticipate the impact of each project on the adjacent tenancy.

Chevron as a corporation is extremely focused on safety. Another important
aspect of construction preplanning is anticipating the risks inherent to each
job. Plaza Tower has established a work permit form to help CONTRACTORs assess
risks, consider safety concerns and communicate to the building engineers which
systems they will be affecting. The second page of the work permit is a "job
site check list". This check list asks several questions related to potential
safety concerns. This form is filled out by the mechanical, plumbing, fire
safety and electrical subCONTRACTORs and turned in to the building engineers
office prior to the beginning of each construction job.

Along with the work permit, the building also enforces lock out/log out for
those trades. Each of these CONTRACTORs will follow the procedure as it is
discussed in the attached documentation.

Through out construction, your primary building contact will be Melissa
Wilkowski. She is the Construction Project Mfr. for Chevron (Landlord
Representative) and is responsible for obtaining the necessary documentation for
the project, overseeing the day-to-day construction of the project on behalf of
the building and communicating with our tenants on possible impact to them. You
can reach her at (303) 930-3904.

BUILDING RULES & REGULATIONS

A document is enclosed which discusses the protocol for CONTRACTORs in the
building. This document discusses procedures for after hours work, notices we
require for adjacent or affected tenants as well as written authorization from
our tenants for access to their suite after hours. Please read it thoroughly.

APPROVED LIST OF BIDDERS

Chevron pays close attention to the mechanical, plumbing and electrical
CONTRACTORs who work in the building. By limiting the number of CONTRACTORs who
work on the building systems, we have been successful in maintaining the
integrity of the building and our tenants have experienced very few problems
during construction. A list of preferred CONTRACTORs is enclosed.



<PAGE>   101

BUILDING SUPPLIED MATERIALS FORM

Chevron maintains an inventory of building standard items such as light
fixtures, ceiling tile and grid tee materials. These are specialty items which
typically have a 6 - 8 week lead time. The building has elected to stock these
items so that construction projects are not delayed unnecessarily. Prior to the
beginning of each project, the general CONTRACTOR will estimate the number of
these items he will need to complete the job. During the construction of the
space, the project superintendent will fill out a "Building Supplied Materials"
form to request the amount of product he will need for the project. He will
submit that estimate to the Landlord Representative. The product is charged to
the job when the project is complete.

Many items are listed on the form. Please contact the Construction Project Mgr.
prior to submitting final pricing for the project, to ensure an adequate stock
of these items is available for your project.

LOCK OUT/TAG OUT PROCEDURES

The Plaza Tower One team put this document together to instruct all mechanical,
plumbing and electrical CONTRACTORs on our lock out/tag out procedures. The
building engineer supplies the locks, logs, and signs to the CONTRACTOR after
the CONTRACTOR has submitted a completed work permit for the job. Adequate
notice is required prior to scheduling work. A copy of the work permit is
enclosed.

Please read through all of the enclosed documentation. If you have any
questions, please call Melissa Wilkowski, Construction Project Manager for
Chevron Real Estate Mgt. Company prior to commencing any work. You can reach her
at (303) 930-3904.

                                 PLAZA TOWER ONE
                        Lockout (and or Tagout) Procedure

PURPOSE

This procedure establishes the minimum requirements for the lockout and or
tagout of energy isolating device(s). It shall be used to ensure that machines,
valves, and equipment are isolated from all potentially hazardous energy, and
locked out and or tagged out before employees perform any service or maintenance
activities where the unexpected energization, start-up or release of stored
energy could cause injury. If the employee's company lockout and or tagout
procedure exceeds these minimum requirements, that employee must abide by them.

RESPONSIBILITY

The following list of employees are authorized to lockout/tagout electrical and
mechanical equipment at PTO

                        Lockout (and or Tagout) Procedure

SEQUENCE OF LOCKOUT AND OR TAGOUT SYSTEM PROCEDURE

1)      Person requesting equipment lockout/tagout will fill out and sign Work
        Permit located at front lobby desk in designated folder and return it to
        one of the employees authorized to lockout/tagout equipment at least 24
        hours in advance.

2)      Employees authorizing Work Permit will notify all affected employees
        that a lockout and or tagout system is going to be utilized and the
        reason therefore.

3)      Employee authorizing lockout/tagout shall know the type and magnitude of
        energy that the machine or equipment utilizes and understand the hazards
        thereof or shall delay the work until he/she does.

4)      If the machine or equipment is operating, the employee authorizing
        lockout/tagout will shut it down by the normal stopping procedure
        (depress stop button, open toggle switch etc.)

5)      Employee authorizing lockout/tagout may then operate the switch(s),
        valve(s), or other energy isolating device(s) so that the equipment is
        isolated from its energy sources). Stored energy (such as that in
        springs, elevated machine members, rotating flywheels, hydraulic
        systems, and air, gas, steam, or water pressure, electricity, etc.) must
        be dissipated or restrained by methods such as repositioning, blocking,
        bleeding down, etc.

Gentlemen:

Chevron Corporation and its subsidiaries are covered for property and liability
exposures through major worldwide insurance programs with large deductibles.
Losses that fall within these deductible levels, including those for, which a
Chevron company is contractually liable, are paid through the financial
resources of the Company and are administered by Chevron Corporation under its
Self-Administered Claims Program, hereinafter referred to as the Program.

This is to advise you Chat the property/liability insurance requirements of the
subject contract(s) fall within the deductible levels of Chevron's insurance
programs. Therefore, losses for which Chevron is responsible under the contract
will be handled under the above-described Program. The scope of this program is
equal to the insurance requirement, of the subject contract.

We further advise you Chat Workers' Compensation insurance requirements for
Chevron companies are satisfied through insured/self-insured programs depending
upon the location of the employee's workplace. U.S. Longshore and Harbor
Workers' Act coverage is self-insured.

Unless cancelled earlier, this letter will remain in effect until the expiration
or earlier termination of the subject contract (or any renewal thereof), if this
program is cancelled or materially changed, we will provide you with 30 days'
written notice.



Yours truly,

        WHEREAS, Landlord's predecessor-in-interest, Huntington Beach Company,
entered rate a written lease agreement with Sublessor, dated April 21, 1995, as
amended by that certain First Amendment to Plaza Tower Office Lease dated May

Sublessor certain premises in the building known as Plaza Tower One (the
"Building"), consisting of approximately 64,473 rentable square feet (the
"Premises"); and

        WHEREAS, Landlord is the owner of the Building and has succeeded to all
of the rights of Huntington Beach Company under the Master Lease; and

        WHEREAS, Sublessor desires to sublet a portion of the Premises
containing approximately 3,667 rentable square feet located on the fifth (5th)
floor of the Building (the "Subleased Premises") to Sublessee and Sublessee

        NOW, THEREFORE, Landlord hereby consents to the sublease of the

        1.      The Sublease shall be subject and subordinate at all times to

<PAGE>   137

        3.      Sublessee agrees that no alterations, additions or physical
changes will be made in the Subleased Premises or any part thereof without
Landlord's prior written consent in each instance.

        4.      This Consent by Landlord shall not be deemed in any way or
manner a release of Sublessor from any and all obligations to be performed by
Sublessor as the Tenant under the Master Lease. The parties hereto agree that
Landlord may, after a default by Sublessor under the Master Lease, collect all
rents due and owing from Sublessee, and such collection thereof shall not be
deemed a waiver of any rights and remedies of Landlord against Sublessor as the
Tenant under the Master Lease.

        5.      Notwithstanding anything to the contrary contained in the
Sublease, nothing therein, or contained in this Consent, shall enlarge or
increase Landlord's obligations or liability under the Master Lease or
otherwise, and in the event of a default in the Master Lease which results in a
termination thereof, the Sublease and Sublessee's rights in the Subleased
Premises shall also be terminated.

        6.      Upon the effective date of the Sublease, Sublessee agrees to
comply with all applicable terms and conditions of the Master Lease. This
Consent by Landlord shall not act to bind Landlord to perform any of the
obligations of Sublessor as may be provided in the Sublease.

        7.      Landlord hereby certifies that, to the best of its actual
knowledge, as of the date of this Consent, Sublessor is not in default under any
of the terms of the Master Lease, nor is there any condition which, with notice
or the passage of time or both, would constitute a default by Sublessor under
the Master Lease.

        8.      Pursuant to Section 12.C. of the Master Lease, Sublessor shall
pay to Landlord one-half of the total consideration received by Sublessor from
Sublessee during the Sublease term (including revenue derived from any subleased
parking spaces), less the gross rents paid by Sublessor to Landlord during the
period of the Sublease term ("Excess Rents"), after first deducting the
following costs and expenses associated with the subletting of the Subleased
Premises from the consideration received from Sublessee, which costs shall be
reasonable: (i) any improvement allowance or other economic concession paid by
Sublessor to Sublessee; (ii) broker's commissions paid by Sublessor with regard
to the subletting; (iii) attorneys' fees; (iv) lease takeover payments; (v)
costs of advertising the Premises for sublease; and (vi) the unamortized cost of
initial and subsequent improvements to the Premises made by Sublessor.

        9.      This Consent to Sublease constitutes the entire and complete
agreement of the parties with respect to the subject matter hereof, and
supersedes all prior or contemporaneous agreements, statements, promises,
understandings, arrangements, and commitments, all of which, whether oral or
written, are merged herein.

        10.     Each party represents that the person executing this Consent for
such party is acting on behalf of such party and is duly authorized to execute
this Consent for such party.

Sublease or Sub-sublease Agreement and (b) any damage or injury to persons or
property occurring upon or in connection with the use or occupancy of the

thereof or of any remainder of the term of this Sub-sublease Agreement shall
release Sub-sublessee from any of its obligations hereunder unless accepted by
Sub-sublessor in writing. The receipt and retention by Sub-sublessor of monthly
base rent or additional rent from anyone other than Sub-sublessee shall not be
deemed a waiver of the breach by Sub-sublessee of any covenant, agreement, term
or provision of this Sub-sublease Agreement, or as the acceptance of such other
person as a tenant, or as a. release of Sub-sublessee from the further keeping,
observance or performance by Sub-sublessee of the covenants, agreements, terms,

ARTICLE 2 AGREEMENT

In consideration for the Rent and other covenants and agreements made by Tenant,
Landlord leases the Premises to Tenant, and Tenant leases the Premises from
Landlord, according to this Lease. The duration of this Lease will be the Term.
The Term will commence on the Commencement Date and will expire on the
Expiration Date unless terminated earlier pursuant to the terms of this Lease.

ARTICLE 3 TERM, DELIVERY, AND ACCEPTANCE OF PREMISES

3.1     DELIVERY OF POSSESSION. Landlord will be deemed to have delivered
        possession of the Premises to Tenant on the Commencement Date, as it may
        be adjusted pursuant to the Workletter. Landlord will construct or
        install in the Premises the improvements as defined in the Workletter to
        be constructed or installed by Landlord according to the Workletter.
        Except as expressly set forth in the Workletter, Landlord shall deliver
        to Tenant possession of the Premises AS IS in its present condition on
        the Commencement Date. Tenant acknowledges that neither Landlord nor its
        agents or employees have made any representations or warranties as to
        the suitability or fitness of the Premises for the conduct of Tenant's
        business or for any other purpose, nor has Landlord or its agents or
        employees agreed to undertake any alterations or construct any Tenant
        improvements to the Premises except as expressly provided in this Lease
        and the Workletter. If for any reason Landlord cannot deliver possession
        of the Premises to Tenant on the Commencement Date, this Lease will not
        be void or voidable, and Landlord will not be liable to Tenant for any
        resultant loss or damage. Tenant will execute and deliver to Landlord
        the Commencement Date and Estoppel Certificate attached to this Lease as
        Exhibit E within 3 days of Landlord's request.

3.2     EARLY ENTRY. If Tenant is permitted entry to the Premises prior to the
        Commencement Date for the purpose of installing fixtures or any other
        purpose permitted by Landlord, the early entry will be at Tenant's sole
        risk and subject to all the terms and provisions of this Lease as though
        the Commencement Date had occurred, except for the payment of Rent,
        which will commence on the Commencement Date. Tenant, its agents, or
        employees will not interfere with or delay Landlord's completion of
        construction of the improvements. Tenant hereby agrees to indemnify
        Landlord against any injury, and loss or damage which may occur to any
        person or to any of the Tenant's work or installations made in such
        Premises, Building or Project, or to any personal property placed
        therein, the same being at Tenant's sole risk, and, prior to any early
        entry by Tenant, provide Landlord with proof of insurance coverages
        described in this Lease. Landlord has the right to impose additional
        conditions on Tenant's early entry that Landlord, in its reasonable
        discretion, deems appropriate and Landlord will further have the right
        to require that Tenant execute an early entry agreement containing those
        conditions prior to Tenant's early entry.

ARTICLE 4 MONTHLY RENT

Throughout the Term of this Lease, Tenant will pay Monthly Rent to Landlord as
rent for the Premises. Monthly Rent will be paid in advance on or before the
first day of each calendar month of the Term. If the Term commences on a day
other than the first day of a calendar month or ends on a day other than the
last day of a calendar month, then Monthly Rent will be appropriately prorated
by Landlord based on the actual number of calendar days in such month. If the
Term commences on a day other than the first day of a calendar month, then the
prorated Monthly Rent for such month will be paid on or before the first day of
the Term. Monthly Rent will be paid to Landlord, without written notice or
demand, and without deduction or offset, in lawful money of the United States of
America at Landlord's address, or to such other address as Landlord may from
time to time designate in writing.

ARTICLE 5 INCREASES IN TAXES AND OPERATING EXPENSES

        to Landlord as additional rent, "Tenant's Share of Taxes" (as
        hereinafter defined) and "Tenant's Share of Operating Expenses" (as
        hereinafter defined) for each such calendar year which is in excess of
        Tenant's Share of Taxes or Tenant's Share of Operating Expenses (either
        or both, as the case may be) for the Base Year as more fully described
        in this Article 5.

5.2     DEFINITIONS. As used in this Article 5, or elsewhere in this Lease, the
        following terms shall be defined as hereinafter set forth:

        (a)     "TAXES" shall mean all real estate taxes and assessments,
                general or special, ordinary or extraordinary, foreseen or
                unforeseen, imposed upon the Project, and any existing or future
                improvements of whatever kind thereto or thereon. Taxes shall
                include, without limitation, any assessment imposed by any
                public or private entity by reason of the Project being located
                in a special services district or similar designation. If, due
                to a future change in the method of taxation, any franchise,
                income, profit or other tax, however designated, shall be levied
                or imposed in substitution, in whole or in part, for (or in lieu
                of) any tax which would otherwise be included within the
                definition of Taxes, such other tax shall be deemed to be
                included within Taxes as defined herein.

                the Building and related facilities and amenities; (C) costs of

                repair of the Building and related facilities and amenities; (D)
                costs of electricity, steam, water, fuel, heating, lighting, air
                conditioning, newer and other utilities chargeable to the
                operation and maintenance of the Building; (E) cost of insurance
                for and relating to the Project, including fire and extended
                coverage (or such greater coverages as Landlord may elect to
                carry) boiler, water damage, public liability and property

                reimbursed to Landlord by such other occupants (or if Landlord
                self insures the Project or any part thereof, a sum in lieu
                thereof which is not in excess of the then prevailing rates for
                such insurance for comparable projects); (F) costs of supplies;
                (G) coals of window cleaning, janitorial services, security
                services, landscaping, snow and ice removal and painting; (H)
                sales or use taxes on supplies and services; (I) consulting,
                accounting fees, legal, tax appeal, engineering and other
                professional fees and expenses; (J) management fees, or if no
                managing agent is employed by Landlord a sum in lieu thereof
                which is not in excess of the then prevailing rates for
                management fees for comparable projects; (K) alterations and
                improvements to the Project which are not capital in nature made
                by reason of any requirement of any insurance underwriters or
                any federal, state, or local statutes, regulations, ordinances,
                or other any duly constituted public authorities having
                jurisdiction over the Premises (hereinafter a Governmental
                Requirement); and (L) without limiting any of the foregoing, any
                other expense or charge which, in accordance with sound
                accounting and management principles generally accepted, would
                be construed as an operating expense. The term "Operating
                Expenses" shall not include: (A) The cost of redecorating or
                repairing, or special cleaning or other services, not provided
                on a regular basis to office tenants of the Building; (B) wages,
                salaries or fees paid to executive personnel of Landlord; (C)
                the cost of any replacement item which, by standard accounting
                practice, should be capitalized (except as otherwise provided in
                subsection (3) below: (D) any charge for depreciation or
                interest paid or incurred by Landlord; (E) any charge for
                Landlord's income tax, excess profit taxes, franchise taxes or
                similar taxes on Landlord's business; (F) leasing commissions;
                (G) real estate taxes; or (H) legal fees for the negotiation or
                enforcement of leases. If Landlord is not furnishing any
                particular work or service (the cost of which, if performed by
                Landlord, would constitute an Operating Expense) to a tenant who
                has undertaken to perform such work or service in lieu of
                performance by Landlord, Operating Expenses shall nevertheless
                be deemed to include the amount Landlord would reasonably have
                incurred if Landlord had in fact performed the work or service
                at its expense.

(2)     Tenant's Expense Share is a fixed percentage and does not vary with
        changing occupancy levels of the Building. Operating Expenses are
        computed for the Building as a whole.* Accordingly, in order to
        stabilize the calculation of increase in Operating Expenses on a square
        foot basis for the Demised Premises, a further adjustment is to be made
        as follows: In determining Operating Expenses for any year, if the
        Building was less than 95% occupied during such entire year, or was not
        in operation during such entire year, then Operating Expenses shall be
        annualized by Landlord (taking into account seasonal variations) and
        adjusted to reflect the amount that such expenses would normally be
        expected to have been, in the reasonable estimate of Landlord, had the
        Building been 95% occupied and operational throughout such year, except
        that in no event shall such adjustment result in an amount less than the
        actual Operating Expenses.

(3)     In the event Landlord shall make a capital expenditure for an "Essential
        Capital Improvement", as hereinafter defined in this subsection (3),
        during any year, the annual amortization of such expenditure (determined
        by dividing the amount of the expenditure by the useful life of the
        improvement, as determined by the Landlord), together with interest at
        the greater of the Prime Rate prevailing plus 2% or Landlord's actual
        borrowing rate for such Essential Capital Improvement, shall be deemed
        an Operating Expense for each year of such useful life. As used herein,
        an "Essential Capital Improvement" means any of the following:

        (A)     a labor saving device, energy saving device or other
                installation, improvement or replacement which reduces Operating
                Expenses as referred to above, whether or not voluntary or
                required by governmental mandate; or

        (B)     an installation, change, improvement, addition, alteration or
                removal of any architectural barriers, whether or not the
                foregoing are structural in nature, made by reason of any
                Governmental Requirements whether or not such Governmental
                Requirement existed on the date of execution of this Lease if
                such Governmental Requirement is or will be applicable generally
                to similar office buildings; or

        (C)     an installation or improvement which directly enhances the
                health or safety of tenants in the Building generally, whether
                or not voluntary or required by governmental mandate (as, for
                example, but without limitation, for fire safety or security).

5.3     SHARE OF TAXES

        (a)     Increases in Taxes. For and with respect to each calendar year
                within which the term of this Lease (and any renewal or
                extension thereof) falls, there shall accrue, as additional
                rent, the amount, if any, by which Tenant's Share of Taxes for
                such calendar year (annualized for any partial year) exceeds the
                Tenant's Share of Taxes for the Base Year. Such additional rent
                shall be prorated on a per-diem basis for any partial calendar
                year included within the term. Such additional rent for any
                calendar year is hereinafter referred to as an "Increase in
                Taxes", and one-twelfth (1/12) of such amount is hereinafter
                referred to as a "Monthly Tax Increase",

        (b)     Payment of Increase In Taxes. At Landlord's option, each
                Increase in Taxes shall be paid with respect to each calendar
                year in either or both of the following manners:

                (l)     Within thirty (30) days after receipt from Landlord of a
                        Statement of Taxes (defined below) containing the amount
                        due from Tenant on account of the Increase in Taxes, but
                        in any event at least thirty (30) days prior to the last
                        date the tax in question is payable by Landlord to the
                        taxing authority with discount; or

                (2)     At any time during the term of this Lease, or any
                        extension or renewal hereof, Landlord may decide that in
                        lieu of a one time payment of the Increase in Taxes
                        provided in Subparagraph (5.3)(1) above, Landlord may
                        require Tenant to pay any Increase in Taxes in
                        accordance with Subparagraph (5.3)(d) below.

        (c)     Statement of Tax Increases. On or before sixty (60) days after
                Landlord receives any statement of Taxes due from the applicable
                governmental agency (or as soon thereafter as practicable),
                Landlord shall furnish to Tenant a "Statement of Taxes" setting
                forth, in reasonable detail:

                (1)     The Amount of Taxes for the calendar Year for which
                        Taxes are payable to the taxing authority;

                (2)     The Increase in Taxes for such calendar Year;

                (3)     The amount, if any, previously paid by Tenant to
                        Landlord on account of any Increase in Taxes for such
                        calendar year;

                (4)     The amount due from Tenant on account of any Increase in
                        Taxes; and

                (5)     If applicable, the Monthly Tax Increase payable during
                        the calendar year.

        (d)     Payment of Increase in Taxes on a Monthly Basis. At Landlord's
                option, payment of additional rent due on account of an Increase
                in Taxes for any given calendar year shall be made in advance as
                follows:

                (1)     On the first day of the first month following either
                        receipt by Tenant of the Statement of Taxes or, if
                        later, notice of Landlord's election to have an Increase
                        in Taxes paid on a monthly basis, Tenant shall pay to
                        Landlord an amount equal to the Monthly Tax Increase
                        multiplied by the number of months fully or partially
                        elapsed in the calendar year (including the month in
                        which the payment is made); and

                (2)     Commencing on the first day of the second month
                        following either receipt by Tenant of the Statement of
                        Taxes or, if later, notice of Landlord's election, and
                        continuing until the receipt by Tenant of the next
                        Statement of Taxes, the minimum monthly installments of
                        rent due hereunder shall be increased by an amount equal
                        to the Monthly Tax Increase, subject to the provisions
                        set forth in Subparagraph 5.3(e) below; and

                (3)     Any overpayment by Tenant of additional rent due on
                        account of the Increase in Taxes shall be adjusted by a
                        credit to Tenant given contemporaneously with the
                        furnishing of the next Statement of Taxes.

        (e)     Optional Billing for Taxes. At Landlord's option, exercisable
                with respect to any one or more calendar years during the term
                of this Lease, Landlord may include, within the Statement of
                Taxes furnished to Tenant pursuant to Subparagraphs 5.3(c) and
                5.3(d) above, Landlord's good faith estimate of Taxes for the
                following calendar year, and the estimated annual Increase in
                Taxes based thereon. In such case, the "Monthly Tax Increase" as
                used in Subparagraph 5.3(d) above, for the computation of
                Tenant's payments to Landlord during the calendar year on
                account of the Increase in Taxes payable to the taxing authority
                for the following calendar year shall be equal to one-twelfth
                (1/12) of the aforesaid estimated Increase in Taxes.



                                     Page 5

5.4     FINAL DETERMINATIONS. For purposes of Section 5.3 above, any assessment
        upon which Tenant's Share of Taxes is based shall be deemed to be the
        amount initially assessed until such time as an abatement, refund,
        rebate or increase, if any (retroactive or otherwise), shall be finally
        determined to be due, and upon such final determination, Landlord shall
        promptly notify Tenant of the amount if any due to Tenant or Landlord,
        as the case may be, as a result of the adjustment, and appropriate
        payment to Landlord or Tenant, as the case may be, shall thereafter be
        promptly made. Landlord shall have no duty to Tenant to contest, appeal
        or otherwise challenge any Taxes. In the event of any reduction in Taxes
        by reason of legal or other action taken by Landlord in contest of same,
        there shall be added to and be deemed a part of the Taxes in question
        the amount of Landlord's legal and other costs and expenses in obtaining
        the reduction (but not an amount in excess of the tax savings).

5.5     OPERATING EXPENSES.

        (a)     Share of Operating Expenses. For and with respect to each
                calendar year of the term of this Lease (and any renewals or
                extensions thereof) there shall accrue, as additional rent, the
                amount, if any, by which Tenant's Share of Operating Expenses
                for such calendar year exceeds Tenant's Share of Operating
                Expenses for the Base Year. Such additional rent shall be
                prorated on a per-diem basis for any partial calendar year. Such
                additional rent for any calendar year is hereinafter referred to
                as the "Operating Expense Increase," and one-twelfth of such
                amount is hereinafter referred to as the "Monthly Increase."

        (b)     Comparative Statements: Payments. On or before April 30 (or as
                soon thereafter as practicable) of each calendar year during the
                term hereof, and any renewals and extensions thereof, Landlord
                shall furnish to Tenant a statement of Operating Expenses
                prepared by Landlord setting forth, in reasonable detail: (1)
                Operating Expenses for the preceding calendar year, (2) the
                Operating Expense Increase for the preceding calendar year, (3)
                the amount, if any paid by Tenant to Landlord during, the
                preceding calendar year on account of said Operating Expense
                Increase, (4) the amount due by Tenant on account of the
                Operating Expense Increase, and (5) the Monthly Increase.
                Payment of the additional rent due on account of the Operating
                Expense Increase for the preceding calendar year shall be made
                by Tenant within fifteen (15) days after receipt by Tenant of
                such statement. Tenant shall also make payments to Landlord, on
                account of the Operating Expense Increase for the then current
                calendar year, as follows:

                (1)     On the first day of the first month following receipt by
                        Tenant of the annual statement, Tenant shall pay to
                        Landlord an amount equal to the Monthly Increase
                        multiplied by the number of months fully or partially
                        elapsed in the current calendar year (including the
                        month in which the payment is made), less any payments
                        which may have been made for such elapsed months
                        pursuant to Subparagraph 5.5(c) below;

                (2)     Commencing on the first day of the second month
                        following receipt by Tenant of the annual comparative
                        statement, and continuing until the receipt by Tenant of
                        the next annual statement, the minimum monthly
                        installments of rent due hereunder shall be increased by
                        an amount equal to the Monthly Increase, subject to the
                        provisions set forth in Subparagraph 5.5(c) below. Any
                        overpayment by Tenant of additional rent due on account
                        of the Operating Expense Increase shall be adjusted by a
                        credit to Tenant given contemporaneously with the
                        furnishing of the next comparative statement.

        (c)     Optional Billing for Operating Expenses. At Landlord's option,
                exercisable with respect to any one or more calendar years
                during the term of this Lease, Landlord may include, within the
                comparative statement furnished to Tenant pursuant to
                Subparagraph 5.5(b) above, Landlord's good faith estimate of
                Operating Expenses for the then current calendar year, and the
                estimated annual Operating Expense Increase based thereon. In
                such case, the "Monthly Increase" as used in Subparagraph 5.5(b)
                above for the computation of Tenant's payments on account of the
                Operating Expense Increase for the current year, shall be equal
                to one-twelfth of the aforesaid estimated Operating Expense
                Increase.

5.6     DISPUTES. The information set forth on each Comparative Statement of
        Operating Expenses and on each Statement of Taxes furnished to Tenant as
        provided hereinabove shall be deemed approved by Tenant unless, within
        thirty (30) days after submission to Tenant, Tenant shall notify
        Landlord that it disputes the correctness thereof, specifying in detail
        the basis for such assertion. Pending the resolution of any dispute,
        however, Tenant shall continue to make payments in accordance with the
        information contained in the comparative statement. Landlord agrees to
        promptly provide to Tenant, upon request, extracts from Landlord's books
        and records which are relevant to any items in dispute.

5.7     AUDIT. In the event Tenant elects to audit Landlord's Comparative
        Statement of Operating Expenses or Statement of Taxes in accordance with
        this clause, such audit must be (i) conducted by an independent
        nationally recognized accounting firm that is not being compensated by
        Tenant on a contingency fee basis, and (ii) completed within sixty (60)
        days following Tenant's notice disputing the correctness of the
        Comparative Statement of Operating Expenses pursuant to section 5.6
        above. Furthermore, all of the information obtained through the Tenant's
        audit with respect to financial matters (including, without limitation,
        costs, expenses, income) and any other matters pertaining to the
        Landlord and/or the Project as well as any compromise, settlement, or
        adjustment reached between Landlord and Tenant relative to the results
        of the audit shall be held in strict confidence by the Tenant and its
        officers, agents, and



                                     Page 6
<PAGE>   10
        employees; and Tenant shall cause its auditor and any of its officers,
        agents, and employees to be similarly bound. As a condition precedent to
        Tenant's exercise of its right to audit, Tenant must deliver to Landlord
        a signed confidentiality agreement from the auditor (in form acceptable
        to Landlord) acknowledging that all of the results of such audit as well
        as any compromise, settlement, or adjustment reached between Landlord
        and Tenant shall be held in strict confidence and shall not be revealed
        in any manner to any person except upon the prior written consent of the
        Landlord. Tenant understands and agrees that this provision is of
        material importance to the Landlord and that any violation of the terms
        of this provision shall result in immediate and irreparable harm to the
        Landlord. Landlord shall have all rights allowed by law or equity if
        Tenant, its officers, agents, or employees and/or the auditor violate
        the terms of this provision, including, without limitation, the right to
        terminate this Lease or the right to terminate Tenant's right to audit.

5.8     SURVIVAL AFTER TERMINATION. If, upon termination of this Lease for any
        cause, the amount of any additional rent due pursuant to Article 5 has
        not yet been determined, an appropriate payment from Tenant to Landlord,
        or refund from Landlord to Tenant, shall be made within thirty (30) days
        after Tenant's receipt of such determination from Landlord.

5.9     OTHER TAXES

        (a)     Tenant will reimburse Landlord upon demand for any and all taxes
                payable by Landlord (other than as set forth in sub-paragraph
                (b) below), whether or not now customary or within the
                contemplation of Landlord and Tenant:

                (1)     upon or measured by rent, including without limitation,
                        any gross or revenue tax, sales tax, use tax, excise
                        tax, or value added tax levied by the federal government
                        or any other governmental body with respect to the
                        receipt of rent; and

                (2)     upon this transaction or any document to which Tenant is
                        a party creating or transferring an interest or an
                        estate in the Premises.

        (b)     Tenant will not be obligated to pay any inheritance tax, gift
                tax, transfer tax, franchise tax, income tax (based on net
                income), profit tax, or capital levy imposed upon Landlord.

        (c)     Tenant will pay promptly when due all personal property taxes on
                Tenant's personal property in the Premises and any other taxes
                payable by Tenant that if not paid might give rise to a lien on
                the Premises or Tenant's interest in the Premises.

ARTICLE 6 INSURANCE

6.1     LANDLORD'S INSURANCE. At all times during the Term, Landlord will carry
        and maintain:

        (a)     Fire and extended coverage insurance covering the Project, its
                equipment, common area furnishings, and leasehold improvements
                in the Premises to the extent of the Tenant Finish Allowance (as
                that term is defined in the Workletter);

        (b)     Bodily injury and property damage liability insurance; and

        (c)     Such other insurance as Landlord reasonably determines from time
                to time.

        The insurance coverages and amounts in this Section 6.1 will be
        reasonably determined by Landlord.

6.2     TENANT'S INSURANCE. At all times during the Term, Tenant will carry and
        maintain, at Tenant's expense, the following insurance, in the amounts
        specified below or such other amounts as Landlord may from time to time
        reasonably request, with insurance companies and on forms satisfactory
        to Landlord:

        (a)     Bodily injury and property damage liability insurance, with a
                combined single occurrence limit of not less than $3,000,000 per
                occurrence. All such insurance will be equivalent to coverage
                offered by a commercial comprehensive general liability form,
                including without limitation personal injury, products and
                completed operations, broad form property damage, and
                contractual liability coverage for the performance by Tenant of
                the indemnity agreements set forth in Article 21 of this Lease;

        (b)     Insurance covering all of Tenant's furniture and fixtures,
                machinery, equipment, stock, and any other personal property
                owned and used in Tenant's business and found in, on, or about
                the Project, and any leasehold improvements to the Premises
                other than those provided by Landlord at the beginning of the
                Term, if any, provided pursuant to the Workletter in an amount
                not less than the full replacement cost. Property forms will
                provide coverage on a broad form basis insuring against "all
                risks of direct physical loss," All policy proceeds will be used
                for the repair or replacement of the property damaged or
                destroyed; however, if this Lease ceases under the provisions of
                Article 18, Tenant will be entitled to any proceeds resulting
                from damage to Tenant's furniture and fixtures, machinery,
                equipment, stock, and any other personal property;

        (c)     Worker's compensation insurance insuring against and
                satisfying Tenant's obligations and liabilities under the
                worker's compensation laws of the state in which the Project is
                located, including employer's liability insurance in the limits
                required by file laws of the state in which the Project is
                located; and

        (d)     Owned, hired, or nonowned comprehensive automobile liability at
                a limit of liability not less than $3,000,000 combined bodily
                injury and property damage per occurrence.

        If Tenant fails to obtain or maintain any insurance required hereunder,
        Landlord shall have the option, without assuming any obligation in
        connection therewith, to effect such insurance at the sole cost of the
        Tenant and all outlays by Landlord shall be reimbursed by Tenant to
        Landlord as Additional Rent.

6.3     FORMS OF POLICIES. Certificates of insurance, together with copies of
        the endorsements, when applicable, naming Landlord and any others
        specified by Landlord as additional insurers, will be delivered to
        Landlord prior to Tenant's occupancy of the Premises and from time to
        time at least 10 days prior to the expiration of the term of each such
        policy. All commercial general liability or comparable policies
        maintained by Tenant will name Landlord and such other persons or firms
        as Landlord specifies from time to time as additional insurers,
        entitling them to recover under such policies for any loss sustained by
        them, their agents, and employees, including those losses sustained as a
        result of the negligent acts or omissions of Tenant. All such policies
        maintained by Tenant will provide that they may not be terminated nor
        may coverage be reduced except after 30 days' prior written notice to
        Landlord. All commercial general liability, automobile, and property
        policies maintained by Tenant will be written as primary policies, not
        contributing with and not supplemental to the coverage that Landlord may
        carry.

6.4     WAIVER OF SUBROGATION. Landlord and tenant each waive any and all rights
        to recover against the other or against any other tenant or occupant of
        the Project, or against the officers, directors, shareholders, partners,
        joint venturers, employees, agents, customers, invitees, or business
        visitors of such other party or of such other tenant or occupant of the
        Project, for any loss or damage to such waiving party arising from any
        cause covered by any property insurance required to be carried by such
        party pursuant to this Article 6 or any other property insurance
        actually carried by such party to the extent of the limits of such
        policy. Landlord and Tenant from time to time will cause their
        respective insurers to issue appropriate waiver of subrogation rights
        endorsements to all property insurance policies carried in connection
        with the Project or the Premises or the contents of the Project or the
        Premises. Tenant agrees to cause all other occupants of the Premises
        claiming by, under, or through Tenant to execute and deliver to Landlord
        such a waiver of claims and to obtain such waiver of subrogation rights
        endorsements.

6.5     ADEQUACY OF COVERAGE. Landlord, its agents and employees make no
        representation that the limits of liability specified to be carried by
        Tenant pursuant to this Article 6 are adequate to protect Tenant. If
        Tenant believes that any of such insurance coverage is inadequate,
        Tenant shall obtain such additional insurance coverage as Tenant deems
        adequate, at Tenant's sole expense.

ARTICLE 7 USE

Tenant covenants that the Premises will be used only for general business office
purposes and purposes incidental to that use, and for no other purpose. Tenant
will use the Premises in a careful, safe, and proper manner. Tenant will not use
or permit the Premises to be used or occupied for any purpose or in any manner
prohibited by any applicable laws. Tenant will not commit waste or suffer or
permit waste to be committed in, on, or about the Premises. Tenant will conduct
its business and control its employees, agents, and invitees in such a manner as
not to create any nuisance or interfere with, annoy, or disturb any other Tenant
or occupant of the Project or Landlord in its operation of the Project. Tenant
agrees to take possession of and occupy the entire Premises no later than 60
days after the Commencement Date, and Tenant further agrees to continue to
occupy the Premises throughout the remainder of the Term of this Lease until 90
days prior to the Expiration Date.

ARTICLE 8 REQUIREMENTS OF LAW; FIRE INSURANCE

8.1     GENERAL. At its sole cost and expense, Tenant will promptly comply with
        all laws, statutes, ordinances, codes, and governmental rules,
        regulations, or requirements of federal, state, county, and local
        governmental authorities now in force or in force at any given time
        after the Lease Date, with the requirements of any board of fire
        underwriters or other similar body constituted now or after the Lease
        Date, with any direction or occupancy certificate issued pursuant to any

        all recorded documents affecting the Premises, insofar as they relate to

        (b)     Tenant will not cause or permit the storage, use, generation,
                release, or disposition of any hazardous materials in, on, or
                about the Premises or the Project by Tenant, its agents,
                employees, or contractors. Tenant will not permit the Premises
                to be used or operated in a manner that may cause the Premises
                or the Project to be contaminated by any hazardous materials in
                violation of any hazardous materials laws, Tenant will
                immediately advise Landlord in writing of (1) any and all
                enforcement, cleanup, remedial, removal, or other governmental
                or regulatory actions instituted, completed, or threatened

                the Premises or the Project relating to damage, contribution,
                cost recovery, compensation, loss, or injury resulting from any
                hazardous materials on or about the Premises. Without
                Landlord's prior written consent, Tenant will not take any
                remedial action or enter into any agreements or settlements in
                response to the presence of any hazardous materials in, on, or
                about the Premises.

        (c)     Tenant will be solely responsible for and will defend, indemnify
                and hold Landlord, its agents, and employees harmless from and
                against all claims, costs, expenses, damages, and liabilities,
                including attorneys' fees and costs, arising out of or in
                connection with Tenant's breach of its obligations in this

                defend, indemnify, and hold Landlord, its agents, and employees
                harmless from and against any and all claims, costs, and
                liabilities, including attorneys' fees and costs, arising out of
                or in connection with the removal, cleanup, and restoration work

                property of whatever nature located on the Project to their
                condition existing prior to the appearance of Tenant's hazardous
                materials on the Premises. Tenant's obligations under this
                Article 8 will survive the expiration or other termination of
                this Lease.

        (d)     Added. See Page 9a

8.3     CERTAIN INSURANCE RISKS. Tenant will not do or permit to be done any act
        or thing upon the Premises or the Project which would (a) jeopardize or
        be in conflict with fire insurance policies covering the Project and
        fixtures and property in the Project; (b) increase the rate of fire
        insurance applicable to the Project to an amount higher than it
        otherwise would be for general office use of the Project; or (c) subject
        Landlord to any liability or responsibility for injury to any person or
        persons or to property by reason of any business or operation being
        carried on upon the Premises. If the conduct of the Tenant, or any acts
        or omissions of the Tenant shall cause or result in any increase in
        premiums for insurance carried by the Landlord, whether or not Landlord
        allows such act or omission to continue, Tenant shall pay any increase
        in premium as Additional Rent.

ARTICLE 9 ASSIGNMENT AND SUBLETTING

9.1     GENERAL. Tenant, for itself, its heirs, distributors, executors,
        administrators, legal representatives, successors, and assigns,
        covenants and agrees that it will not assign, mortgage, or encumber this
        Lease, or sublease, nor otherwise permit the Premises or any part of
        the Premises to be used or occupied by others, without the prior written
        consent of Landlord in each instance, which consent may be withheld at
        the Landlord's sole discretion. Landlord may condition its consent upon,
        among other things, execution by the subtenant or assignee, as the case
        may be, of an instrument confirming the restrictions on further
        subleasing or assignment contained herein and joining in the waivers and
        indemnities made by Tenant hereunder. Any assignment or sublease in
        violation of this Article 9 will be void. If this Lease is assigned, or
        if the Premises or any part of the Premises are subleased or occupied by
        anyone other than Tenant, Landlord may, after any default by Tenant,
        collect rent from the assignee, subtenant, or occupant, and apply the
        net amount collected to Rent. No assignment, sublease, occupancy, or
        collection will be deemed (a) a waiver of the provisions of this Section
        9.1; (b) the acceptance of the assignee, subtenant, or occupant as
        Tenant; or (c) a release of Tenant from the further performance by
        Tenant of covenants on the part of Tenant contained in this Lease. The
        consent by Landlord to an assignment or sublease will not be construed
        to relieve Tenant from obtaining Landlord's prior written consent to any
        further assignment or sublease. No permitted subtenant may assign or
        encumber its sublease or further sublease all or any portion of its
        subleased space, or otherwise permit the subleased space or any part of
        its subleased space to be used or occupied by others, without Landlord's
        prior written consent in each instance. Any assignee approved by
        Landlord must assume all of the obligations and duties of Tenant under
        this Lease pursuant to an assumption agreement satisfactory to Landlord
        of which Landlord is the beneficiary. See page 9a.

        (b) the business terms of the proposed assignment or sublease; (c)

        of the Rent allocable to the transferred space then being paid by Tenant
        to Landlord pursuant to this Lease; and (b) any other profit or gain
        (after deducting any necessary expenses incurred) realized by Tenant
        from any such sublease or assignments. All such sums owed to Landlord
        under 9.3(c), above, will be payable to Landlord at the time the next
        payment of Monthly Rent is due.

        Lease, or a majority of the total interest in any partnership Tenant or
        subtenant, however accomplished, and whether in a single transaction or
        in a series of related or unrelated transactions, will be deemed an
        assignment of this lease or of such sublease requiring Landlord's
        consent in each instance. For purposes of this Article 9, the transfer
        of outstanding capital stock of any corporate Tenant will not include
        any sale of such stock by persons other than those deemed "insiders"
        within the meaning of the Securities Exchange Act of 1934, as amended,
        effected through the "over-the-counter market" or through any recognized
        stock exchange.

        contained herein, shall have the following options at its discretion:

                Premises, or any part thereof, as if Landlord was the sublessor
                or assignor, and to do whatever Tenant is permitted to do

                written notice of its desire to do so; (2) the excess services
                are reasonably available to Landlord and to the Premises; and
                (3) Tenant pays as Additional Rent (at the time the next payment
                of Monthly Rent is due) the cost of such excess service from
                time to time charged by Landlord; subject to the procedures
                established by Landlord from time to time for providing such
                additional or excess services.

12.3    TENANT'S COSTS. Whenever equipment or lighting (other than building
        standard lights) is used in the Premises by Tenant and such equipment
        or lighting affects the temperature otherwise normally maintained by the
        design of the Building's air conditioning system, Landlord will bare the
        right, after prior written notice to Tenant, to install supplementary
        air conditioning facilities in the Premises or otherwise modify the
        ventilating slid air conditioning system serving the Premises; and the
        cost of such facilities, modifications, and additional service will be
        paid by Tenant as Additional Rent. If Landlord reasonably believes that
        Tenant is using more power than Landlord furnishes pursuant to Section
        12.2, Landlord may install separate meters of Tenant's power usage, and
        Tenant will pay for the cost of such excess power as Additional Rent,
        together with the cost of installing any risers, meters, or other
        facilities that may be necessary to furnish or measure such excess
        power to the Premises.

 12.4    LIMITATION ON LIABILITY. Landlord will not be in default under this
        Lease or be liable to Tenant or any other person for direct or
        consequential damage, or otherwise, for any failure to supply any heat,
        air conditioning, elevator, cleaning, lighting, or security; for surges
        or interruptions of electricity; or for interruptions to other services
        Landlord has agreed to supply. Landlord will use reasonable efforts to
        diligently remedy any interruption in the furnishing of such services.
        Landlord reserves the right temporarily to discontinue such services at
        such times as may be necessary by reason of accident; repairs,
        alterations or improvements; strikes; lockouts; riots; acts of God;
        governmental preemption in connection with a national or local
        emergency; any rule, order, or regulation of any governmental agency;
        conditions of supply and demand that make any product unavailable;
        Landlord's compliance with any mandatory governmental energy
        conservation or environmental protection program, or any voluntary
        energy conservation program at the request of or with consent or
        acquiescence of Tenant; or any other happening beyond the control of
        Landlord. Landlord will not be liable to Tenant or any other person or
        entity for direct or consequential damages resulting from the admission
        to or exclusion from the Building or Project of any person. In the event
        of invasion, mob, riot, public excitement, strikes, lockouts, or other
        circumstances rendering such action advisable in Landlord's sole
        opinion, Landlord will have the right to prevent access to the Building
        or Project during the continuance of the same by such means as Landlord,
        in its sole discretion, may deem appropriate, including without
        limitation locking doors and closing parking areas and other common
        areas. Landlord will not be liable for damages to person or property or
        for injury to, or interruption of, business for any discontinuance
        permitted under this Article 12, nor will such discontinuance in any way
        be construed as an eviction of Tenant or cause an abatement of Rent or
        operate to release Tenant from any of Tenant's obligations under this
        Lease.

ARTICLE 14 ALTERATIONS

14.1    GENERAL.

        (a)     Tenant will not make or allow to be made any alterations,
                additions, or improvements to or of the Premises or any part of
                the Premises, or attach any fixtures or equipment to the
                Premises, without first obtaining Landlord's written consent. In
                no event shall the work of Tenant affect or impair the
                structure, the elevators, or utility systems of the Building.
                Landlord's approval of the plans, specifications, and working
                drawings for Tenant's alterations shall create no responsibility
                or liability on the part of the Landlord for their completeness,
                design sufficiency, or compliance with all laws, ordinances,
                rules, requirements, and regulations of governmental agencies or
                authorities, or the use and occupancy permit for the Building.
                All such alterations, additions, and improvements consented to
                by Landlord, and capital improvements that are required to be
                made to the Project as a result of the nature of Tenant's use of
                the Premises:

                (1)     Will be performed by contractors approved by Landlord
                        and subject to conditions specified by Landlord (which
                        may include requiring the posting of performance and
                        payment bonds);

                (2)     At Landlord's option, will be made by Landlord for
                        Tenant's account, and Tenant will reimburse Landlord for
                        their cost (including 15% for Landlord's overhead)
                        within 10 days after receipt of a statement of such
                        cost;

                (3)     Will be done in a good and workmanlike manner and shall
                        be completed promptly;

                (4)     Shall not cause a loss or diminution of electric power
                        or other utilities or services to other tenants of the
                        Building;

                (5)     Will be performed according to plans, specifications,
                        and working drawings approved by Landlord; and

                (6)     Will be in accordance with all applicable federal,
                        state, county and local laws, rules, regulations,
                        ordinances and codes.

        At all times between the start and completion of the work, in addition
        to the other policies of insurance required by this Lease, Tenant shall
        maintain a policy of "All Risk" Builder's Risk Insurance covering the
        full replacement value of all work done and fixtures and equipment
        installed or to be installed at the Premises pursuant to this Article
        14. Tenant herewith agrees to be responsible for all damages to persons
        or property, including loss of life, as a result of occurrences
        connected with activities undertaken by

ARTICLE 13 TENANTS CARE OF THE PREMISES (ADDED)

Tenant will not act or fail to act in a manner causing damage to the Premises
(including Tenant's equipment, personal property, and trade fixtures located in
the Premises) in their condition at the time they were delivered to Tenant,
reasonable wear and tear excluded. Tenant will immediately advise Landlord of
any damage to the Premises or Project. All damage or injury to the Premises, the
Project or the fixtures, appurtenances, and equipment in the Premises or the
Project that is caused by Tenant, its agents, employees, or invitees and not
covered by insurance may be repaired, restored, or replaced by Landlord, at the
expense of Tenant. Such expense (plus 5% of such expense for Landlord's
overhead) will be collectible as Additional Rent and will be paid by Tenant
within 10 days after delivery of a statement for such expense.



                                    Page 12a

<PAGE>   19
Tenant, its agents, contractors, and employees pursuant hereto, and hereby
indemnifies Landlord and shall defend and hold Landlord harmless from and
against any and all loss, cost or expense in connection with its
responsibilities hereunder.

        (b)     Subject to Tenant's rights in Article 16, all alterations,
                additions, fixtures, and improvements, whether temporary or
                permanent in character, made in or upon the Premises either by
                Tenant or Landlord, will immediately become Landlord's property
                and at the end of the Term will remain on the Premises without
                compensation to Tenant, unless Landlord at the time of approval
                of same advises Tenant in writing that such alterations,
                additions, fixtures, or improvements must be removed at the
                expiration or other termination of this Lease.

14.2    FREE-STANDING PARTITIONS. Tenant will have the right to install
        free-standing work station partitions, without Landlord's prior written
        consent, so long as no building or other governmental permit is required
        for their installation or relocation; however, if a permit is required,
        Landlord will not unreasonably withhold its consent to such relocation
        or installation. The free-standing work station partitions for which
        Tenant pays will be part of Tenant's trade fixtures for all purposes
        under this Lease. All other partitions installed in the Premises are
        and will be Landlord's property for all purposes under this Lease.

14.3    REMOVAL. If Landlord has required Tenant to remove any or all
        alterations, additions, fixtures, and improvements that are made in or
        upon the Premises pursuant to this Article 14 prior to the Expiration
        Date, Tenant will remove such alterations, additions, fixtures, and
        improvements at Tenant's sole cost and will restore the Premises to the
        condition in which they were before such alterations, additions,
        fixtures, improvements, and additions were made.

ARTICLE 15 MECHANICS' LIENS

Tenant will pay or cause to be paid all costs and charges for work (a) done by
Tenant or caused to be done by Tenant, in or to the Premises, and (b) for all
materials furnished for or in connection with such work. Tenant will indemnify
Landlord against and defend and hold Landlord, the Premises, and the Project
free, clear, and harmless of and from all mechanics' liens and claims of liens,
and all other liabilities, liens, claims, and demands on account of such work by
or on behalf of Tenant, other than work performed by Landlord pursuant to the
Workletter. If any such lien, at any time, is filed against the Premises or any
part of the Project, Tenant will cause such lien to be discharged of record
within 10 days after the filing of such lien, except that if Tenant desires to
contest such lien, it will furnish Landlord, within such 10-day period, security
reasonably satisfactory to Landlord of at least 150% of the amount of the claim,
plus estimated costs and interest, or comply with such statutory procedures as
may be available to release the lien. If a final judgement establishing the
validity or existence of a lien for any amount is entered, Tenant will pay and
satisfy the same at once. If Tenant fails to pay any charge for which a
mechanics' lien has been filed, and has not given Landlord security as described
above, or has not complied with such statutory procedures as may be available to
release the lien, Landlord may, at its option, pay such charge and related costs
and interest, and the amount so paid, together with reasonable attorneys' fees
incurred in connection with such lien, will be immediately due from Tenant to
Landlord as Additional Rent. Nothing contained in this Lease will be deemed the
consent or agreement of Landlord to subject Landlord's interest in the Project
to liability under any mechanics' or other lien law. If Tenant receives written
notice that a lien has been or is about to be filed against the Premises or the
Project, or that any action affecting title to the Project has been commenced on
account of work done by or for or materials furnished to or for Tenant, it will
immediately give Landlord written notice of such notice. At least 15 days prior
to the commencement of any work (including but not limited to any maintenance,
repairs, alterations, additions, improvements, or installations) in or to the
Premises, by or for Tenant, Tenant will give Landlord written notice of the
proposed work and the names and addresses of the persons supplying labor and
materials for the proposed work. Landlord will have the right to post notices of
nonresponsibility or similar written notices on the Premises in order to protect
the Premises against any such liens.

ARTICLE 16 END OF TERM

At the end of this Lease, Tenant will promptly quit and surrender the Premises
broom-clean, in good order and repair, ordinary wear and tear excepted and
deliver all keys to the Premises and the Building to Landlord. If Tenant is not
then in default, Tenant may remove from the Premises any trade fixtures,
equipment, and movable furniture placed in the Premises by Tenant, whether or
not such trade fixtures or equipment are fastened to the Building; Tenant will
not remove any trade fixtures or equipment without Landlord's prior written
consent if such fixtures or equipment are used in the operation of the Building,
or if the removal of such fixtures or equipment will result in impairing the
structural strength of the Building. Whether or not Tenant is in default, Tenant
will remove such alterations, additions, improvements, trade fixtures,
equipment, and furniture as Landlord has requested in accordance with Article
14. Tenant will fully repair any damage occasioned by the removal of any trade
fixtures, equipment, furniture, alterations, additions, and improvements. All
trade fixtures, equipment, furniture, inventory, effects, alterations,
additions, and improvements on the Premises after the end of the Term will be
deemed conclusively to have been abandoned and may be appropriated, sold,
stored, destroyed, or otherwise disposed of by Landlord without notice to Tenant
or any other person and without obligation to account for them. Tenant will pay



                                     Page 13

<PAGE>   20
Landlord for all expenses incurred in connection with the removal of such
property, including but not limited to the cost of storage, and the cost of
repairing any damage to the Building or Premises caused by the removal of such
property. Tenant's obligation to observe and perform this covenant will survive
the expiration or other termination of this Lease.

ARTICLE 17 EMINENT DOMAIN

If all of the Premises are taken by exercise of the power of eminent domain (or
conveyed by Landlord in lieu of such exercise) this Lease will terminate on a
date (the "termination date") which is the earlier of the date upon which the
condemning authority takes possession of the Premises or the date on which title
to the Premises is vested in the condemning authority. If more than 25% of the
Rentable Area of the Premises is so taken, Tenant will have the right to cancel
this Lease by written notice to Landlord given within 20 days after the
termination date. If less than 25% of the Rentable Area of the Premises is so
taken, or if the Tenant does not cancel this Lease according to the preceding
sentence, the Monthly Rent will be abated in the proportion of the Rentable Area
of the Premises so taken to the Rentable Area of the Premises immediately before
such taking, and Tenant's Share will be appropriately recalculated. If 25% or
more of the Building or the Project is so taken, Landlord may cancel this Lease
by written notice to Tenant given within 30 days after the termination date. In
the event of any such taking, the entire award will be paid to Landlord, and
Tenant will have no right or claim to any part of such award; however, Tenant
will have the right to assert a claim against the condemning authority in a
separate action, so long as Landlord's award is not reduced as a consequence of
such claim, for Tenant's costs including but not limited to moving expenses and
trade fixtures owned by Tenant.

ARTICLE 18 DAMAGE AND DESTRUCTION

        (a)     If the Premises or the Building is damaged by fire or other
                insured casualty, Landlord will give Tenant written notice of
                the time which will be needed to repair such damage, as
                determined by Landlord in its reasonable discretion, and the
                election (if any) which Landlord has made according to this
                Article l8. Such notice will be given before the 30th day (the
                "notice date,") after the fire, or other insured casualty.

        (b)     If the Premises or the Building is damaged by fire or other
                insured casualty to an extent which may be repaired within 180
                days after the notice date, as reasonably determined by
                Landlord, Landlord will promptly begin to repair the damage
                after the notice date and will diligently pursue the completion
                of such repair. In that event this Lease will continue in full
                force and effect except that Monthly Rent will be abated on a
                pro rata basis from the date of the damage until the date of the
                completion of such repairs (the "repair period") based on the
                proportion of the Rentable Area of the Premises Tenant is unable
                to use during the repair period.

        (c)     If the Premises or the Building is damaged by fire or other
                insured casualty to an extent that may not be repaired within
                180 days after the notice date, as reasonably determined by
                Landlord, then (1) Landlord may cancel this Lease as of the date
                of such damage by written notice given to Tenant on or before
                the notice date or (2) Tenant may cancel this Lease as of the
                date of such damage by written notice given to Landlord within
                10 days after landlord's delivery of a written notice that the
                repairs cannot be made within such 180 day period. If neither
                Landlord nor Tenant so elects to cancel this Lease, Landlord
                will diligently proceed to repair the Building and Premises and
                Monthly Rent will abated on a pro rata basis during the repair
                period based on the proportion of the Rentable Area of the
                Premises Tenant is unable to use during the repair period.

        (d)     Notwithstanding the provisions of subparagraphs (a), (b), and
                (c) above, if the Premises or the Building or the Project are
                damaged by uninsured casualty, or if the proceeds of insurance
                are insufficient to pay for the repair of any damage to the
                Premises or the Building or the Project, Landlord will have the
                option to repair such damage or cancel this Lease as of the date
                of such casualty by written notice to Tenant on or before the
                notice date.

        (e)     If any such damage by fire or other casualty is the result of
                the willful conduct or negligence or failure to act of Tenant,
                its agents, contractors, employees, or invitees, there will be
                no abatement of Monthly Rent as otherwise provided for in this
                Article 18. Tenant will have no rights to terminate this Lease
                on account of any damage to the Premises, the Building, or the
                Project, except as set forth in this Lease.

        (f)     For purposes of this Article 18 and subject to subsections (a)
                thru (e) hereof, Landlord shall repair or restore any portion of
                the alterations, additions or improvements in the Premises or
                the decorations thereto to the extent that such alterations,
                additions, improvements and decorations were provided by
                Landlord at the beginning of the Term. Landlord shall have no
                further obligations pursuant to this Lease to repair or restore
                any alterations, additions or improvements in the Premises or
                the decorations thereto. If Tenant desires any other or
                additional repairs or restoration and if Landlord consents
                thereto, the same shall be done at Tenant's sole cost and
                expense. Tenant acknowledges that Landlord shall be entitled to
                the full proceeds of any insurance coverage, carried by Landlord
                to the extent of damage to alterations, additions, improvement
                or decorations.

ARTICLE 19 SUBORDINATION

19.1    GENERAL. This Lease and Tenant's rights under this Lease are subject and
        subordinate to any ground or underlying lease, mortgage, indenture, deed
        of trust, or other lien encumbrance (each a "superior lien"), together
        with any renewals, extensions, modifications, consolidations, and
        replacements of such superior lien, now or in the future affecting or
        placed, charged, or enforced against the Land, the Building, or all or
        any portion of the Project or any interest of Landlord in them or
        Landlord's interest in this Lease and the leasehold estate created by
        this Lease (except to the extent any such instrument expressly provides
        that this Lease is superior to such instrument). Notwithstanding the
        foregoing, Tenant will execute, acknowledge, and deliver to Landlord,
        within 20 days after written demand by Landlord, such documents as may
        be reasonably requested by Landlord or the holder of any superior lien
        to confirm or effect any such subordination or superiority, as
        applicable, see page 15a.

19.2    ATTORNMENT. Tenant agrees that in the event that any holder of a
        superior lien succeeds to Landlord's interest in the Premises, Tenant
        will pay to such holder all Rent subsequently payable under this Lease.
        Further, Tenant agrees that in the event of the enforcement by the
        holder of a superior lien of the remedies provided for by law or by such
        superior lien, Tenant will, upon request of any person or party
        succeeding to the interest of Landlord as a result of such enforcement,
        automatically become the Tenant of and attorn to such successor in
        interest without change in the terms or provisions of this Lease. Such
        successor in interest will not be bound by:

        (a)     Any payment of Rent for more than one month in advance, except
                prepayments in the nature of security for the performance by
                Tenant of its obligations under this Lease that are actually
                received by such successor in interest;

        (b)     Any amendment or modification of this Lease made without the
                written consent of such successor in interest (if such consent
                was required under the terms of such superior lien);

        (c)     Any claim against Landlord arising prior to the date on which
                such successor in interest succeeded to Landlord's interest; or

        (d)     Any claim or offset of Rent against the Landlord.

        Upon request by such successor in interest and without cost to Landlord
        or such successor in interest, Tenant will, within 20 days after written
        demand, execute, acknowledge, and deliver an instrument or instruments
        confirming the attornment.

ARTICLE 20 ENTRY BY LANDLORD

Landlord, its agents, employees, and contractors may enter the Premises at any
time in response to an emergency and at any other reasonable time to:

        (a)     Inspect the Premises;

        (b)     Exhibit the Premises to prospective purchasers, lenders, or
                tenants;

        (c)     Determine whether Tenant is complying with all its obligations
                in this Lease;

        (d)     Supply cleaning service and any other service to be provided by
                Landlord to Tenant according to this Lease;

        (e)     Post written notices of nonresponsibility or similar notices; or

        (f)     Make repairs required of Landlord under the terms of this Lease
                or make repairs to any adjoining space or utility services or
                make repairs, alterations, or improvements to any other portion
                of the Building.

Tenant, by this Article 20, waives any claim against Landlord, its agents,
employees, or contractors for damages for any injury or inconvenience to or
interference with Tenant's business, any loss of occupancy or quiet enjoyment of
the Premises, or any other loss occasioned by any entry in accordance with this
Article 20. Landlord will at all times have and retain a key with which to
unlock all of the doors in, on, or about the Premises (excluding Tenant's
vaults, safes, and similar areas designated in writing by Tenant in advance).
Landlord will have the right to use any and all means Landlord may deem proper
to open doors in and to the Premises in an emergency in order to obtain entry to
the Premises, provided that Landlord will promptly

repair any damages caused by any forced carry, Any carry to the Premises by
Landlord in accordance with this Article 20 will not be construed or deemed to
be a forcible or unlawful entry into or a detainer of the Premises or an
eviction, actual or constructive, of Tenant from the Premises or any portion of
the Premises, nor will any such entry entitle Tenant to damages or an abatement
of Monthly Rent, Additional Rent, or other charges that this Lease requires
Tenant to pay.

ARTICLE 21 INDEMNIFICATION, WAIVER, AND RELEASE

21.1    INDEMNIFICATION. To the extent not prohibited by law, Landlord, its
        employees and agents shall not be liable for damage to person, property
        or business or resulting from the loss of use thereof sustained by
        Tenant or other persons due to the Building or any part thereof becoming
        out of repair or due to an accident or due to any act or neglect of any
        tenant, occupant or other person.* Tenant further agrees that all
        personal property upon the Premises, loading dock, holding areas, and
        freight elevators shall be at the sole risk of Tenant. *unless as a
        result of Landlord's intentional act or omission Tenant will neither
        hold nor attempt to hold Landlord, its employees, or agents liable for,
        and Tenant will indemnify and defend and hold harmless Landlord, its
        employees, and agents from and against, any and all demands, claims,
        causes of action, fines, penalties, damages (including consequential
        damages), liabilities, judgments, and expenses (including without
        limitation reasonable attorneys' fees) incurred in connection with or
        arising from:

        (a)     the use or occupancy or manner of use or occupancy of the
                Premises or any common areas by Tenant or any person claiming
                under Tenant;

        (b)     any activity, work, or thing done or permitted by Tenant in or
                about the Premises, the Building, or the Project;

        (c)     any breach by Tenant or its employees, agents, contractors, or
                invitees of this Lease; and

        (d)     any injury or damage to the person, property, or business of
                Tenant, its employees, agents, contractors, or invitees entering
                upon the Premises under the express or implied invitation of
                Tenant.

        If any action or proceeding is brought against Landlord, its employees,
        or agents by reason of any such claim for which Tenant has indemnified
        Landlord, Tenant, upon written notice from Landlord, will defend the
        same at Tenant's expense, with counsel reasonably satisfactory to
        Landlord.

21.2    WAIVER AND RELEASE. Tenant, as a material part of the consideration to
        Landlord for this Lease, by this Section 21.2 waives and releases all
        claims against Landlord, its employees, and agents with respect to all
        matters for which Landlord has disclaimed liability pursuant to the
        provisions of this Lease.

ARTICLE 22 SECURITY DEPOSIT

Upon execution of this Lease, Tenant shall deposit the security deposit with
Landlord as security for the full, faithful, and timely performance of every
provision of this Lease to be performed by Tenant. If Tenant defaults with
respect to any provision of this Lease, including but not limited to the
provisions relating to the payment of Rent, Landlord may use, apply, or retain
all or any part of the security deposit for the payment of any Rent, or any
other sum in default, or for the payment of any other amount Landlord may spend
or become obligated to spend by reason of Tenant's default, or to compensate
Landlord for any other loss or damage Landlord may suffer by reason of Tenant's
default. If any portion of the security deposit is so used, applied, or
retained, Tenant will within 5 days after written demand deposit cash with
Landlord in an amount sufficient to restore the security deposit to its original
amount. Landlord will not be required to keep the security deposit separate from
its general funds, and Tenant will not be entitled to interest on the security
deposit. The security deposit will not be deemed a limitation on Landlord's
damages or a payment of liquidated damages or a payment of the Monthly Rent due
for the last month of the Term. If Tenant fully, faithfully, and timely performs
every provision of this Lease to be performed by it, the security deposit or any
balance of the security deposit will be returned to Tenant within 60 days after
the expiration of the Term. Landlord may deliver the balance of the security
deposit then held by Landlord to the purchaser of the Building in the event the
Building is sold or to any transferee or assignee from Landlord, and after such
time Landlord will have no further liability to Tenant with respect to the
security deposit.

ARTICLE 23 QUIET ENJOYMENT

Landlord covenants and agrees with Tenant that so long as Tenant pays the Rent
and observes and performs all the terms, covenants, and conditions of this
Lease on Tenant's part to be observed and performed, Tenant may peaceably and
quietly enjoy the Premises subject, nevertheless, to the terms and conditions of
this Lease, and Tenant's possession will not be disturbed by anyone claiming by,
through, or under Landlord.



                                     Page 16

<PAGE>   24
ARTICLE 24 EFFECT OF SALE

A sale, conveyance, or assignment of the Building or the Project will operate to
release Landlord from liability from and after the effective date of such sale,
conveyance, or assignment upon all of the covenants, terms, and conditions of
this Lease, express or implied, except those liabilities that arose prior to
such effective date, and, after the effective date of such sale, conveyance, or
assignment, Tenant will look solely to Landlord's successor in interest in and
to this Lease. This Lease will not be affected by any such sale, conveyance, or
assignment, and Tenant will attorn to Landlord's successor in interest to this
Lease from and after such effective date.

ARTICLE 25 DEFAULT

25.1    EVENTS OF DEFAULT. The following events are referred to, collectively,
        as "events of default" or, individually, as an "event of default":

        (a)     Tenant fails to pay any Rent or other monetary obligation when
                due, and such failure continues for 5 days after written notice
                from Landlord; however, Tenant will not be entitled to more
                than 1 written notice for monetary defaults during any 12-month
                period, and if after such written notice any Rent is not paid
                when due, an event of default will be considered to have
                occurred without further notice;

        (b)     Tenant vacates or abandons the Premises;

        (c)     This Lease or the Premises or any part of the Premises is taken
                upon execution or by other process of law directed against
                Tenant, or is taken upon or subject to any attachment by any
                creditor of Tenant or claimant against Tenant, and said
                attachment is not discharged or disposed of within 15 days after
                its levy;

        (d)     Tenant or any guarantor of Tenant's obligations under this Lease
                ("Guarantor") files a petition in bankruptcy or insolvency or
                for reorganization or arrangement under the bankruptcy laws of
                the United States or under any insolvency act of any state, or
                admits the material allegations of any such petition by answer
                or otherwise, or admits in writing its inability to meet its
                debts as they mature, or is dissolved or makes an assignment for
                the benefit of creditors;

        (e)     Involuntary proceedings under any such bankruptcy law or
                insolvency act or for the dissolution of Tenant or any Guarantor
                are instituted against Tenant or any Guarantor, or a receiver or
                trustee is appointed for all or substantially all of the
                property of Tenant or any Guarantor, and such proceeding is not
                dismissed or such receivership or trusteeship vacated within 60
                days after such institution or appointment;

        (f)     Tenant fails to take possession of the Premises on the
                Commencement Date of the Term;

        (g)     Tenant violates the terms of Article 9 "Assignment and
                Subletting";

        (h)     Tenant breaches any of the agreements, terms, covenants, or
                conditions of this Lease and such breach involves a hazardous
                condition and is not cured immediately upon written notice to
                Tenant;

        (i)     Tenant breaches any of the other agreements, terms, covenants,
                or conditions that this Lease requires Tenant to perform, and
                such breach continues for a period of 30 days after written
                notice from Landlord to Tenant or, if such breach cannot be
                cured reasonably within such 30-day period, if Tenant fails to
                diligently commence to cure such breach within 30 days after
                written notice from Landlord and to complete such cure within a
                reasonable time thereafter; or

25.2    LANDLORD'S REMEDIES. If any one or more events of default set forth in
        Section 25.1 occurs then Landlord has the right, at its election:

        (a)     To give Tenant written notice of Landlord's intention to
                terminate this Lease on the earliest date permitted by law or on
                any later date specified in such notice, in which case Tenant's
                right to possession of the Premises will cease and this Lease
                will be terminated, except as to Tenant's liability, as if the
                expiration of the term fixed in such notice were the end of the
                Term;

        (b)     Without further demand or notice, and without terminating this
                Lease, to reenter and take possession of the Premises or any
                part of the Premises, repossess the same, expel Tenant and those
                claiming through or under Tenant, and remove the effects of both
                or either, using such force for such purposes as may be
                necessary, without being liable for prosecution, without being
                deemed guilty of any manner of trespass, and without prejudice
                to any remedies for arrears of Monthly Rent or other amounts
                payable under this Lease or as a result of any preceding breach
                of covenants or conditions; or


                                     Page 17
<PAGE>   25

        (c)     Without further demand or notice to cure any event of default
                and to charge Tenant for the cost of effecting such cure,
                including without limitation reasonable attorneys' fees and
                interest on the amount so advanced at the rate set forth in
                Section 27.21, provided that Landlord will have no obligation to
                cure any such event of default of Tenant.

        Should Landlord elect to reenter as provided in subsection (b), or
        should Landlord take possession pursuant to legal proceedings or
        pursuant to any notice provided by law, Landlord may, from time to time,
        without terminating this Lease, relet the Premises or any part of the
        Premises in Landlord's or Tenant's name, but for the account of Tenant,
        for such term or terms (which may be greater or less than the period
        which would otherwise have constituted the balance of the Term) and on
        such conditions and upon such other terms (which may include concessions
        of free rent and alteration and repair of the Premises) as Landlord, in
        its reasonable discretion, may determine, and Landlord may collect and
        receive the rents from such reletting. Landlord will in no way be
        responsible or liable for any failure to relet the Premises, or any part
        of the Premises, or for any failure to collect any rent due upon such
        reletting. No such reentry or taking possession of the Premises by
        Landlord will be construed as an election on Landlord's part to
        terminate this Lease unless a written notice of such intention is given
        to Tenant. No written notice from Landlord under this Section or under a
        forcible or unlawful entry and detainer statute or similar law will
        constitute an election by Landlord to terminate this Lease unless such
        notice specifically so states. Landlord reserves the right following any
        such reentry or reletting to exercise its right to terminate this Lease
        by giving Tenant such written notice, in which event this Lease will
        terminate as specified in such notice.

25.3    CERTAIN DAMAGES. In the event that Landlord does not elect to terminate
        this Lease as permitted in Section 25.2(a), but on the contrary elects
        to take possession as provided in Section 25.2(b), Tenant will pay to
        Landlord Monthly Rent and other sums as provided in this Lease that
        would be payable under this Lease if such repossession had not occurred,
        less the net proceeds, if any, of any reletting of the Premises after
        deducting all of Landlord's reasonable expenses in connection with such
        reletting, including without limitation all repossession costs,
        brokerage commissions, attorneys' fees, expenses of employees,
        alteration and repair costs, and expenses of preparation for such
        reletting. Tenant will pay such Rent and other sums to Landlord monthly
        on the day on which the Monthly Rent would have been payable under this
        Lease if possession had not been retaken, and Landlord will be entitled
        to receive such Rent and other sums from Tenant on each such day.

25.4    CONTINUING LIABILITY AFTER TERMINATION. If this Lease is terminated on
        account of the occurrence of an event of default, Tenant will remain
        liable to Landlord for damages in an amount equal to the Rent and other
        amounts that would have been owing by Tenant for the balance of the
        Term, had this Lease not been terminated, less the net proceeds, if any,
        of any reletting of the Premises by Landlord subsequent to such
        termination, after deducting all of Landlord's expenses in connection
        with such reletting, including without limitation the expenses
        enumerated in Section 25.3. Landlord will be entitled to collect such
        damages from Tenant monthly on the day on which Monthly Rent and other
        amounts would have been payable under this Lease if this Lease had not
        been terminated, and Landlord will be entitled to receive such Monthly
        Rent and other amounts from Tenant on each such day. Alternatively, at
        the option of Landlord, in the event this Lease is so terminated,
        Landlord will be entitled to recover against Tenant as damages for loss
        of the bargain and not as a penalty:

        (a)     The worth at the time of award of the unpaid Rent that had been
                earned at the time of termination;

        (b)     The worth at the time of award of the amount by which the unpaid
                Rent that would have been earned after termination until the
                time of award exceeds the amount of such rental loss that Tenant
                proves could have been reasonably avoided;

        (c)     The worth at the time of award of the amount by which the unpaid
                Rent for the balance of the Term of this Lease (had the same not
                been so terminated by Landlord) after the time of award exceeds
                the amount of such rental loss that Tenant proves could be
                reasonably avoided;

        (d)     Any other amount necessary to compensate Landlord for all the
                detriment proximately caused by Tenant's failure to perform its
                obligations under this Lease or which in the ordinary course of
                things would be likely to result therefrom.

        The "worth at the time of award" of the amounts referred to in clauses
        (a) and (b) above is computed by adding interest at the per annum
        interest rate described in Section 27.21 on the date on which this Lease
        is terminated from the date of termination until the time of the award.
        The "worth at the time of award" of the amount referred to in clause (c)
        above is computed by discounting such amount at the discount rate of the
        Federal Reserve Bank of New York, New York, at the time of award plus
        1%.

25.5    CUMULATIVE REMEDIES. Any suit or suits for the recovery of the amounts
        and damages set forth in Sections 25.3 and 25.4 may be brought by
        Landlord, from time to time, at Landlord's election, and nothing in this
        Lease will be deemed to require Landlord to await the date upon which
        this Lease or the Term would have expired had there occurred no event of
        default. Each right and remedy provided for in this Lease is cumulative
        and is in addition to every other right or remedy provided for in this
        Lease or now or after the Lease Date existing at law or in equity or by
        statute or otherwise, and the exercise



                                     Page 18

<PAGE>   26

        or beginning of the exercise by Landlord of any one or more at the
        rights or remedies provided for in this Lease or now or after the Lease
        Date existing at law or in equity or by statute or otherwise will not
        preclude the simultaneous or later exercise by Landlord of any or all
        other rights or remedies provided for in this Lease or now or after the
        Lease Date existing at law or in equity or by statute or otherwise. All
        costs incurred by Landlord in collecting any amounts and damages owing
        by Tenant pursuant to the provisions of this Lease or to enforce any
        provision of this Lease, including reasonable attorneys' fees from the
        date any such matter is turned over to an attorney, whether or not one
        or more actions are commenced by Landlord, will also be recoverable by
        Landlord from Tenant. *See Page 19a.

25.6    WAIVER OF REDEMPTION. Tenant waives any right of redemption arising as a
        result of Landlord's exercise of its remedies under this Article 25.

ARTICLE 26 PARKING

Tenant will be entitled to use only the parking spaces set forth in Section
1.1(q) during the Term subject to the rules and regulations set forth in Exhibit
D, and any amendments or additions to them. Tenant's parking spaces will be
unassigned, nonreserved, and nondesignated.

Neither Landlord nor any operator of the parking areas within the Project, as
the same are designated and modified by Landlord, in its sole discretion, from
time to time (the "parking areas") will be liable for loss of or damage to any
vehicle or any contents of such vehicle or accessories to any such vehicle, or
any property left in any of the parking areas, resulting from fire, theft,
vandalism, accident, conduct of other users of the parking areas and other
persons, or any other casualty or cause. Further, Tenant understands and agrees
that: (a) Landlord will not be obligated to provide any traffic control,
security protection or operator for the parking areas; (b) Tenant uses the
parking areas at its own risk; and (c) Landlord will not be liable for personal
injury or death, or theft, loss of, or damage to property. Tenant waives and
releases Landlord from any and all liability arising out of the use of the
parking areas by Tenant, its employees, agents, invitees and visitors, whether
brought by any of such persons or any other person.

Tenant's right to use the parking areas will be in common with other tenants of
the Project and with other parties permitted by Landlord to use the parking
areas. Landlord reserves the right to assign and reassign, from time to time,
particular parking spaces for use by persons selected by Landlord, provided that
Tenant's rights under the Lease are preserved. Landlord will not be liable to
Tenant for any unavailability of Tenant's designated spaces, if any, nor will
any unavailability entitle Tenant to any refund, deduction, or allowance. Tenant
will not park in any numbered space or any space designated as: RESERVED,
HANDICAPPED, VISITORS ONLY, or LIMITED TIME PARKING (or similar designation).

If the parking areas are damaged or destroyed, or if the use of the parking
areas is limited or prohibited by any governmental authority, or the use or
operation of the parking areas is limited or prevented by strikes or other labor
difficulties or other causes beyond Landlord's control and parking is restored
within a reasonable period of time Tenant's inability to use the parking spaces
will not subject Landlord or any operator of the parking areas to any liability
to Tenant and will not relieve Tenant of any of its obligations under the Lease
and the Lease will remain in full force and effect.

Tenant has no right to assign or sublicense any of its rights in the parking
spaces, except as part of a permitted assignment or sublease of the Lease.

ARTICLE 27 MISCELLANEOUS

27.1    NO OFFER. Submission of the Lease to Tenant is for examination and shall
        not bind Landlord in any manner. No lease or obligations of Landlord
        shall arise until this instrument is signed by both Landlord and Tenant
        and delivery is made to each; provided, however, the execution and
        delivery by Tenant of this Lease to Landlord or Landlord's agent shall
        constitute an irrevocable offer by Tenant to lease the Premises on the
        terms and conditions herein contained, which offer may not be withdrawn
        or revoked for 15 days after such execution and delivery.

27.2    JOINT AND SEVERAL LIABILITY. If Tenant is composed of more than one
        signatory to this Lease, each signatory will be jointly and severally
        liable with each other signatory for payment and performance according
        to this Lease. The act of, written notice to, written notice from,
        refund to, or signature of any signatory to this Lease (including
        without limitation modifications of this Lease made by fewer than all
        such signatories) will bind every other signatory as though every other
        signatory had so acted, or received or given the written notice or
        refund, or signed.

27.3    NO CONSTRUCTION AGAINST DRAFTING PARTY. Landlord and Tenant acknowledge
        that each of them and their counsel have had an opportunity to review
        this Lease and that this Lease will not be construed against Landlord
        merely because Landlord has prepared it.

27.4    TIME OF THE ESSENCE. Time is of the essence of each and every provision
        of this Lease.

MBL Office Lease for MPower Solutions, Inc.

Para 25.5 added: Notwithstanding the foregoing, Landlord waives any right,
whether statutory or otherwise, to a lien against Tenant's personal property.



                                    Page 19a

<PAGE>   28

27.5    NO RECORDATION. Tenant's recordation of lifts Lease or any memorandum or
        short form of it will be void and an event of default under this Lease.
        Tenant shall, at the request of Landlord, execute a short-form lease and
        have it properly acknowledged for the purpose of recording. The cost of
        recording such short-form lease shall be borne by Landlord.

27.6    NO WAIVER. No waiver by Landlord of any agreement, condition or
        provision contained in this Lease will be valid or binding unless
        expressed in writing and signed by Landlord. The waiver by Landlord of
        any agreement, condition, or provision contained in this Lease will not
        be deemed to be a waiver of any subsequent breach of the same or any
        other agreement, condition, or provision contained in this Lease, nor
        will any custom or practice that may grow up between the parties in the
        administration of the terms of this Lease be construed to waive or to
        lessen the right of Landlord to insist upon the performance by Tenant in
        strict accordance with the terms of this Lease. The subsequent
        acceptance of Rent by Landlord will not be deemed to be a waiver of any
        preceding breach by Tenant of any agreement, condition, or provision of
        this Lease, other than the failure of Tenant to pay the particular Rent
        so accepted, regardless of Landlord's knowledge of such preceding breach
        at the time of acceptance of such Rent.

27.7    LIMITATION ON RECOURSE. Tenant specifically agrees to look solely to
        Landlord's interest in the Project for the recovery of any judgments
        from Landlord. It is agreed that Landlord (and its agents, shareholders,
        venturers, and partners, and their shareholders, venturers, and partners
        and all of their officers, directors, and employees) will not be
        personally liable for any such judgments.

27.8    ESTOPPEL CERTIFICATES. At any time and from time to time but with 15
        days after prior written request by Landlord, Tenant will execute,
        acknowledge, and deliver to Landlord or such other person as Landlord
        shall direct, promptly upon request, a certificate* certifying (a) that
        this Lease is unmodified and in full force and effect or, if there have
        been modifications, that this Lease is in full force and effect, as
        modified, and stating the date and nature of each modification; (b) the
        date, if any, to which Rent and other sums payable under this Lease
        have been paid; (c) that no written notice of any default has been
        delivered to Landlord which default has not been cured, except as to
        defaults specified in said certificate; (d) that the Tenant has no
        knowledge of and that there is no event of default under this Lease or
        an event which, with notice or the passage of time, or both, would
        result in an event of default under this Lease, except for defaults
        specified in said certificate; and (e) such other matters as may be
        reasonably requested by Landlord. Any such certificate may be relied
        upon by any prospective purchaser or existing or prospective mortgagee
        or beneficiary under any deed of trust of the Building or any part of
        the Project. Tenant's failure to deliver such a certificate within such
        time will be conclusive evidence of the matters set forth in it, and
        such failure shall be an event of default. *See Page 20a.

27.9    ATTORNEYS' FEES. If Landlord and Tenant litigate any provision of this
        Lease or the subject matter of this Lease, the unsuccessful litigant
        will pay to the successful litigant all costs and expenses, including
        reasonable attorneys' fees and court costs, incurred by the successful
        litigant at trial and on any appeal. If, without fault, either Landlord
        or Tenant is made a party to any litigation instituted by or against the
        other, the other will indemnify the faultless one against all loss,
        liability, and expense, including reasonable attorneys' fees and court
        costs, incurred by it in connection with such litigation.

27.10   NO MERGER. The voluntary or other surrender of this Lease by Tenant or
        the cancellation of this Lease by mutual agreement of Tenant and
        Landlord or the termination of this Lease on account of Tenant's default
        will not work a merger, and will, at Landlord's option, (a) terminate
        all or any subleases and subtenancies or (b) operate as an assignment to
        Landlord of all or any subleases or subtenancies. Landlord's option
        under this Section 27.10 will be exercised by written notice to Tenant
        and all known subleases or subtenants in the Premises or any part of the
        Premises.

27.11   HOLDING OVER. Tenant will have no right to remain in possession of all
        or any part of the Premises after the expiration of the Term* and
        Landlord may, at its option, re-enter and take possession of the
        Premises, reserving its rights to collect damages sustained by reason of
        Tenant's unlawful retention of possession of the Premises or any part
        thereof. If Tenant remains in possession of all or any part of the
        Premises after the expiration of the Term, with the express written
        consent of Landlord: (a) such tenancy will be deemed to be a periodic
        tenancy from month-to-month only; (b) such tenancy will not constitute
        a renewal or extension of this Lease for any further term; and (c) such
        tenancy may be terminated by Landlord upon the earlier of 30 days' prior
        written notice or the earliest date permitted by law. In such event,
        Monthly Rent will be increased to an amount equal to 140% of the Monthly
        Rent payable during the last month of the Term, and any other sums due
        under this Lease will be payable in the amount and at the times
        specified in this Lease. During such month-to-month tenancy, Tenant will
        observe every other term, condition, and covenant contained in this
        Lease. *See Page 20a

27.12   NOTICES. Any notice, request, demand, consent, approval, or other
        communication required or permitted under this Lease must be in writing
        and will be deemed to have been given when personally delivered, sent by
        facsimile with delivery acknowledged by the sending machine, deposited

        default or, in the event the alleged default cannot reasonably be cured
        within a 30-day period, to commence action and proceed diligently to
        cure such alleged default. A copy of such notice to Landlord will be
        sent to any holder of a mortgage or other encumbrance on the Building or

RULES AND REGULATIONS

        1.      Landlord may from time to time adopt appropriate systems and
procedures for the security or safety of the Building, any persons occupying,
using, or entering the Building, or any equipment, finishings, or contents of
the Building, and Tenant will comply with Landlord's reasonable requirements
relative to such systems and procedures.

        2.      The sidewalks, passages, exits, entrances, and stairways of the
Building will not be obstructed by any tenants or used by any of them for any
purpose other than for ingress to and egress from their respective Premises. No
tenant and no employee or invitee of any tenant will go upon the roof of the
Building except to perform required repairs or maintenance, and then only after
Tenant has obtained Landlord's consent. No tenant will be permitted to place or
install any object (including without limitation radio and television antennas,
loudspeakers, sound amplifiers, microwave dishes, solar devices, or similar
devices) on the exterior of the Building or on the roof of the Building.

        3.      No sign, placard, picture, name, advertisement, exterior light,
decoration, balloon, flag, pennant, banner or written notice visible from the
exterior of Tenant's Premises will be inscribed, painted, affixed, or otherwise
displayed by Tenant on any part of the Building or the Premises without the
prior written consent of Landlord. Landlord will adopt and furnish to Tenant
general guidelines relating to exterior signs and to signs inside the Building
but visible from outside the Premises. Tenant agrees to conform to such
guidelines. All approved signs or lettering on doors will be printed, painted,
affixed, or inscribed at the expense of the Tenant by a person approved by
Landlord. Tenant shall repair, paint, and/or replace the building fucia surface
to which its signs are attached upon vacation of the Premises, or the removal or
alteration of its signage. Tenant shall not make any changes to the exterior of
the Premises except as approved in writing by Landlord. In the event of the
violation of this rule by Tenant, Landlord may remove the violating items
without any liability, and may charge the expense incurred by such removal to
the tenant or tenants violating this rule.

        4.      No cooking will be done or permitted by any tenant on the
Premises, except in areas of the Premises which are specially constructed for
cooking and except that use by the tenant of microwave ovens and Underwriters'
Laboratory approved equipment for brewing coffee, tea, hot chocolate, and
similar beverages will be permitted, provided that such use is in accordance
with all applicable federal, state, and city laws, codes, ordinances, rules and
regulations.

        5.      No tenant will employ any person or persons other than a
cleaning service approved by Landlord for the purpose of cleaning the Premises,
unless otherwise agreed to by Landlord in writing. Except with the written
consent of Landlord, no person or persons other than those approved by Landlord
will be permitted to enter the Building for the purpose of cleaning it. No
tenant will cause any unnecessary labor by reason of such tenant's carelessness
or indifference in the preservation of good order and cleanliness. Should
Tenant's actions result in any increased expense for any required cleaning,
Landlord reserves the right to assess Tenant for such expenses.

        6.      The toilet rooms, toilets, urinals, wash bowls and other
plumbing fixtures will not be used for any purposes other than those for which
they were constructed, and no sweepings, rubbish, rags, or other foreign
substances will be thrown in such plumbing fixtures. All damages resulting from
any misuse of the fixtures will be borne by the tenant who, or whose servants,
employees, agents, visitors, or licensees, caused the same.

        7.      No tenant or tenant's invitees or licensees, will in any way
deface any part of the Premises or the Building of which they form a part. In
those portions of the Premises where carpet has been provided directly or
indirectly by Landlord, Tenant will at its own expense install and maintain pads
to protect the carpet under all furniture having casters and other than carpet
casters.

        8.      No tenant will alter, change, replace, or rekey any lock or
install a new lock or a knocker on any door of the Premises. Landlord, its
agents, or employees will retain a pass (master) key to all door locks on the
Premises. Any new door locks required by Tenant or any change in keying of
existing locks will be installed or changed by Landlord following tenant's
written request to Landlord and will be at Tenant's expense. All new locks and
rekeyed locks will remain operable by Landlord's pass (master) key. Landlord
will furnish each tenant, free of charge, with two (2) keys to each suite entry
door lock on the Premises. Landlord will have the right to collect a reasonable
charge for additional keys and cards requested by any tenant. Each tenant, upon
termination of its tenancy, will deliver to Landlord all keys and access cards
for the Premises and Building that have been furnished to such tenant.

The moving company must be a locally recognized professional mover, whose
primary business is the performing of relocation services, and must be bonded
and fully insured. A certificate or other verification of such insurance must be
received and approved by Landlord prior to the start of any moving operations.
Insurance must be sufficient, in Landlord's sole opinion, to cover all personal
liability, theft or damage to the Project, including but not limited to floor
coverings, doors, walls, stairs, foliage, and landscaping. Special care must be
taken to prevent damage to foliage and landscaping during adverse weather. All
moving operations will be conducted at such times and in such a manner as
Landlord will direct, and all moving will take place during non-business hours
unless Landlord agrees in writing otherwise. Tenant will be responsible for the
provision of building security during all moving operations, and will be liable
for all losses and damages sustained by any party as a result of the failure to
supply adequate security. Landlord will have the right to prescribe the weight,
size, and position of all equipment, materials, furniture, or other property
brought into the Building. Heavy objects will, if considered necessary by
Landlord, stand on wood strips of such thickness as is necessary to properly
distribute the weight. Landlord will not be responsible for loss of or damage to
any such property from any cause, and all damage done to the Building by moving
or maintaining such property will be repaired at the expense of Tenant. Landlord
reserves the right to inspect all such property to be brought into the Building
and to exclude from the Building all such property which violates any of these
rules and regulations or the Lease of which these rules and regulations are a
part. Supplies, goods, materials, packages, furniture, and all other items of
every kind delivered to or taken from the Premises will be delivered or removed
through the entrance and route designated by Landlord, and Landlord will not be
responsible for the loss or damage of any such property.

        10.     No tenant will use or keep in the Premises or the Building any
kerosene, gasoline, or inflammable or combustible or explosive fluid or material
or chemical substance other than limited quantities of such materials or
substances reasonably necessary for the operation or maintenance of office
equipment of limited quantities of cleaning fluids and solvents required in
tenant's normal operations in the Premises, which shall be stored in accordance
with applicable law. No storage outside the Premises is permitted. Without
Landlord's prior written approval, no tenant will use any method of heating or
air conditioning other than that supplied by Landlord. No tenant will use or
keep or permit to be used or kept any foul or noxious gas or substance in the
Premises.

        11.     Tenants shall not, prior to or during the Term, either directly
or indirectly, employ or permit the employment of any contractor, mover,
mechanic or laborer, or permit any materials in the Premises. If the use of such
contractor, mover, mechanic or laborer or such materials would, in Landlord's
opinion, create any difficulty, strike or jurisdictional dispute with other
contractors, movers, mechanics or laborers engaged by Landlord, tenants, or
others, or would in any way disturb the construction, maintenance, cleaning,
repair, management, security or operation of the Building, Project or any part
thereof. Any tenant, upon demand by Landlord, shall cause all contractors,
movers, mechanics, laborers or materials causing such interference, difficulty
or conflict to leave or be removed from the Project immediately.

        12.     Landlord will have the right to prohibit any advertising by
Tenant mentioning the Building that, in Landlord's reasonable opinion, tends to
impair the reputation or desirability of the Building, and upon written notice
from Landlord, Tenant will refrain from or discontinue such advertising.

        13.     Tenant will not bring any animals (except "Seeing Eye" dogs) or
birds into the Building, and will not permit bicycles or other vehicles inside
or on the sidewalks outside the Building except in areas designated from time to
time by Landlord for such purposes.

        15.     Each tenant will store all its trash and garbage within its
Premises. No material will be placed in the trash boxes or receptacles if such
material is of such nature that it may not be disposed of in the ordinary and
customary manner of removing and disposing of trash and garbage without being in
violation of any law or ordinance governing such disposal. All garbage and
refuse disposal will be made only through entryways and elevators provided for
such purposes and at such times as Landlord designates. Removal of any furniture
or furnishings, large equipment, packing crates, packing materials, and boxes
will be the responsibility of each tenant and such items may not be disposed of
in the Building trash receptacles nor will they be removed by the Building's
janitorial service, except at Landlord's sole option and at the tenant's
expense. No furniture, appliances, equipment, or flammable products of any type
may be disposed of in the Building trash receptacles.

        16.     Canvassing, peddling, soliciting, and distributing handbills or
any other written materials in the Building are prohibited, and each tenant will
cooperate to prevent the same.

        17.     The requirements of the tenants will be attended to only upon
application by written, personal, or telephone notice to the Landlord's
management company for the Building. Employees of Landlord or Landlord's agent
will not perform any work or do anything outside of their regular duties unless
under special instructions from Landlord.
<PAGE>   39

        18.     A directory of the Building may be, but is not required to be,
provided for the display of the name and location of tenants only. All entries
on any Building directory display will confirm to standards and style set by
Landlord in its sole discretion. Space on any exterior signage will be provided
in Landlord's sole discretion. No tenant will have any right to the use of any
exterior sign.

        19.     Tenant will see that the doors of the Premises are closed and
locked and that all water faucets, water apparatus, and utilities are shut off
before Tenant or Tenant's employees leave the Premises, so as to prevent waste
or damage, and for any failure to comply or carelessness in this regard Tenant
will make good all injuries sustained by the other tenants or occupants of the
Building or Landlord.

        20.     Tenant will not conduct itself in any manner that is
inconsistent with the character of the Building as a first quality building or
that will impair the comfort and convenience of other tenants in the Building.

        21.     Tenant (including tenant's employees, agents, invitees, and
visitors) will use the parking spaces solely for the purpose of parking
passenger model cars, small vans, and small trucks and will comply in all
respects with any rules and regulations that may be promulgated by Landlord from
time to time with respect to the parking areas. The parking areas will not be
used by Tenant, its agents, or employees, for overnight parking of vehicles,
except with Landlord's prior consent. Tenant will ensure that any vehicle parked
in any of the parking spaces will be kept in proper repair and will not leak
oil, grease, gasoline, or any other fluids. If any of the parking spaces are at
any time used (a) for any purpose other than parking as provided above; (b) in
any way or manner reasonably objectionable to Landlord; or (c) by Tenant after
default by Tenant under the Lease, Landlord, in addition to any other rights
otherwise available to Landlord, may consider such default an event of default
under the Lease.

        22.     No act or thing done or omitted to be done by Landlord or
Landlord's agent during the term of the Lease in connection with the enforcement
of these rules and regulations will constitute an eviction by Landlord of any
tenant nor will it be deemed an acceptance of surrender of the Premises by any
tenant, and no agreement to accept such termination or surrender will be valid
unless in a writing signed by Landlord. The delivery of keys to any employee or
agent of Landlord will not operate as a termination of the Lease or a surrender
of the Premises unless such delivery of keys is done in connection with a
written instrument executed by Landlord approving the termination or surrender.

        23.     In these rules and regulations, the term "tenant" includes the
employees, agents, invitees, and licensees of Tenant and others permitted by
Tenant to use or occupy the Premises.

        24.     Landlord may waive any one or more of these rules and
regulations for the benefit of any particular tenant or tenants, but no such
waiver by Landlord will be construed as a waiver of such rules and regulations
in favor of any other tenant or tenants, nor prevent Landlord from enforcing any
such rules and regulations against any or all of the tenants of the Building
after such waiver.

        25.     These rules and regulations are in addition to, and will not be
construed to modify or amend, in whole or in part, the terms, covenants,
agreements, and conditions of the Lease.

In consideration for the Rent and other covenants and agreements made by
Tenant, Landlord leases the Premises to Tenant, and Tenant leases the Premises
from Landlord, according to this Lease. The duration of this Lease will be the
Term. The Term will commence on the Commencement Date and will expire on the
Expiration Date unless terminated earlier pursuant to the terms of this Lease.

ARTICLE 3 TERM, DELIVERY, AND ACCEPTANCE OF PREMISES

3.1  DELIVERY OF POSSESSION. Landlord will be deemed to have delivered
     possession of the Premises to Tenant on the Commencement Date, as it may be
     adjusted pursuant to the Workletter. Landlord will construct or install in
     the Premises the Improvements as defined in the Workletter to be
     constructed or installed by Landlord according to the Workletter. If no
     Workletter is attached to this Lease, it will be deemed that Landlord
     delivered to Tenant possession of the Premises AS IS in its present
     condition on the Commencement Date. Tenant acknowledges that neither
     Landlord nor its agents or employees have made any representations or
     warranties as to the suitability or fitness of the Premises for the conduct
     of Tenant's business or for any other purpose, nor has Landlord or its
     agents or employees agreed to undertake any alterations or construct any
     Tenant Improvements to the Premises except as expressly provided in this
     Lease and the Workletter.* Tenant will execute and deliver to Landlord the
     Commencement Date and Estoppel Certificate attached to this Lease as
     Exhibit E within 3 days of Landlord's request.

3.2  EARLY ENTRY. Tenant shall be permitted entry to the Premises prior to the
     Commencement Date for the purpose of installing fixtures or any other
     purpose permitted by Landlord. The early entry will be at Tenant's sole
     risk and subject to all the terms and provisions of this Lease as though
     the Commencement Date had occurred, except for the payment of Rent, which
     will commence on the Commencement Date. Tenant, its agents, or employees
     will not interfere with or delay Landlord's completion of construction of
     the improvements. Tenant hereby agrees to indemnify Landlord against any
     injury, and loss or damage which may occur to any person or to any of the
     Tenant's work or installations made in such Premises, Building or Project,
     or to any personal property placed therein, the same being at Tenant's sole
     risk, and, prior to any early entry by Tenant, provide Landlord with proof
     of insurance coverages described in this Lease. Landlord has the right to
     impose additional conditions on Tenant's early entry that Landlord, in its
     reasonable discretion, deems appropriate and Landlord will further have the
     right to require that Tenant execute an early entry agreement containing
     those conditions prior to Tenant's early entry.

ARTICLE 4 MONTHLY RENT

Throughout the Term of this Lease, Tenant will pay Monthly Rent to Landlord as
rent for the Premises. Monthly Rent will be paid in advance on or before the
first day of each calendar month of the Term. If the Term commences on a day
other than the first day of a calendar month or ends on a day other than the
last day of a calendar month, then Monthly Rent will be appropriately prorated
by Landlord based on the actual number of calendar days in such month. If the
Term commences on a day other than the first day of a calendar month, then the
prorated Monthly Rent for such month will be paid on or before the first day of
the Term. Monthly Rent will be paid to Landlord, without written notice or
demand, and without deduction or offset, in lawful money of the United States
of America at Landlord's address, or to such other address as Landlord may from
time to time designate in writing.

ARTICLE 5 OPERATING EXPENSES

5.1  GENERAL.

(a)  In addition to Monthly Rent, beginning on the Commencement Date Tenant will
     pay Tenant's Share of the amount by which the operating expenses paid,
     payable, or incurred by Landlord in each calendar year or partial calendar
     year during the Term exceeds the product of the Operating Expense Base
     times the Rentable Area of the Building. If operating expenses are
     calculated for a partial calendar year, the Operating Expense Base will be
     appropriately prorated.

(b)  As used in this Lease, the term "operating expenses" means:

     (1)  All costs of ownership, management, operation, repair and maintenance
          of the Project, including without limitation real and personal
          property taxes and assessments (and any tax levied in whole or in part
          in lieu of or in addition to real property taxes); wages, salaries,
          compensation and benefits of employees; consulting, accounting, legal,
          tax appeal, engineering and other professional fees and expenses;
          janitorial, maintenance, guard, and other services; management fees
          and costs (charged by Landlord, any affiliate of Landlord, or any
          other entity managing the Project and determined at a rate consistent
          with prevailing market rates for comparable services and projects);
          reasonable reserves for operating expenses; that part of office rent
          or rental value of space in the Project used or furnished by Landlord
          to enhance, manage,


*    If for any reason except for Force Majeure as provided in Section 27.32 or
Tenant's actions or inactions, Landlord cannot deliver possession of the
Premises to Tenant within 60 days after November 15, 1995, Tenant may cancel
this Lease and Landlord will not be liable to Tenant for any resultant loss or
damage.

          operate, and maintain the Project; power, water, waste disposal, and
          other utilities; snow, ice, and debris removal; electrical costs;
          materials and supplies; maintenance and repairs including elevator
          maintenance and repairs; service and maintenance contracts; insurance
          obtained with respect to the Project; depreciation on personal
          property and equipment, except as set forth in (c) below or which is
          or should be capitalized on the books of Landlord; and any other
          costs, charges, and expenses that under generally accepted accounting
          principles would be regarded as management, maintenance, and operating
          expenses; and

     (2)  The cost (amortized over such period as Landlord will reasonably
          determine) together with interest at the greater of the Prime Rate
          prevailing plus 2% or Landlord's borrowing rate for such capital
          improvements plus 2% on the unamortized balance of the cost of any
          capital improvements and the installation thereof that are made to the
          Project by Landlord (i) for the purpose of safety, saving energy or
          reducing operating expenses, or (ii) by requirement of any
          governmental law or regulation that was not applicable to the Project
          at the time it was constructed and not as a result of special
          requirements for any tenant's use of the Building.

(c)  The operating expenses will not include:

     (1)  depreciation on the Project (other than depreciation on personal
          property, equipment, window coverings on exterior windows provided by
          Landlord and carpeting in public corridors and common areas);

     (2)  costs of alterations of space or other improvements made for tenants
          of the Project;

     (3)  finders' fees and real estate brokers' commissions;

     (4)  mortgage principal, or interest;

     (5)  capital items other than those referred to in clause (b)(2) above;

     (6)  costs of replacements to personal property and equipment for which
          depreciation costs are included as an operating expense;

     (7)  costs of excess or additional services provided to any tenant in the
          Building that are directly billed to such tenants;

     (8)  the cost of repairs due to casualty or condemnation that are
          reimbursed by third parties;

     (9)  any cost due to Landlord's breach of this Lease;

    (10)  any income, estate, inheritance, or other transfer tax and any excess
          profit, franchise, or similar taxes on Landlord's business;

    (11)  all costs, including legal fees, relating to activities for the
          solicitation and execution of leases of space in the Building; and

    (12)  any legal fees incurred by Landlord in enforcing its rights under
          other leases for premises in the Building.

   (d) The operating expenses that vary with occupancy and that are
       attributable to any part of the Term in which less than 95% of the
       Rentable Area of the Building is occupied by tenants will be adjusted by
       Landlord to the amount that Landlord reasonably believes they would have
       been if 95% of the Rentable Area of the Building had been so occupied.

5.2    ESTIMATED PAYMENTS. At Landlord's request, during each calendar year or
       partial calendar year in the Term, in addition to Monthly Rent, Tenant
       will pay to Landlord on the first day of each month an amount equal to
       1/12 of the product of Tenant's Share multiplied by the "estimated
       operating expenses" (defined below) for such calendar year. "Estimated
       operating expenses" for any calendar year means Landlord's reasonable
       estimate of operating expenses for such calendar year, less the product
       of the Operating Expense Base, multiplied by the Rentable Area of the
       Building and will be subject to revision according to the further
       provisions of this Section 5.2 and Section 5.3. During any partial
       calendar year during the Term, estimated operating expenses will be
       estimated on a full-year basis. During each December during the Term, or
       as soon after each December as practicable, Landlord will give Tenant
       written notice of estimated operating expenses for the ensuing calendar
       year. On or before the first day of each month during the ensuing
       calendar year (or each month of the Term, if a partial calendar year),
       Tenant will pay to Landlord 1/12 of the product of Tenant's Share
       multiplied by the estimated operating expenses for such calendar year;
       however, if such


                                     Page 4



<PAGE>   7
     written notice is not given in December, Tenant will continue to make
     monthly payments on the basis of the prior year's estimated operating
     expenses until the month after such written notice is given, at which time
     Tenant will commence making monthly payments based upon the revised
     estimated operating expenses. In the month Tenant first makes a payment
     based upon the revised estimated operating expenses, Tenant will pay to
     Landlord for each month which has elapsed since December the difference
     between the amount payable based upon the revised estimated operating
     expenses and the amount payable based upon the prior year's estimated
     operating expenses. If at any time or times it reasonably appears to
     Landlord that the actual operating expenses for any calendar year will vary
     from the estimated operating expenses for such calendar year, Landlord may,
     by written notice to Tenant, revise the estimated operating expenses for
     such calendar year, and subsequent payments by Tenant in such calendar year
     will be based upon such revised estimated operating expenses.

5.3  ANNUAL SETTLEMENT. Within 120 days after the end of each calendar year or
     as soon after such 120-day period as practicable, Landlord will deliver to
     Tenant a statement of amounts payable under Section 5.1 for such calendar
     year prepared and certified by Landlord. Such certified statement will be
     final and binding upon Landlord and Tenant unless Tenant objects to it in
     writing to Landlord within 30 days after it is given to Tenant. If such
     statement shows an amount owing by Tenant that is less than the estimated
     payments, if any, previously made by Tenant for such calendar year, the
     excess will be held by Landlord and credited against the next payment of
     Rent; however, if the Term has ended and Tenant was not in default at its
     end, Landlord will refund the excess to Tenant. If such statement shows an
     amount owing by Tenant that is more than the estimated payments, if any,
     previously made by Tenant for such calendar year, Tenant will pay the
     deficiency without deduction or setoff to Landlord within 30 days after
     the delivery of such statement.

     Tenant shall have the right at its own expense and at a reasonable time
     (after written notice to Landlord) within 30 days after receipt of the
     statement to review Landlord's record of operating expenses relevant to
     this Article. In the event Tenant does not review Landlord's records and
     deliver the results thereof to Landlord within said 30 day period, the
     terms and amounts set forth in the statement shall be deemed conclusive
     and final and Tenant shall have no further right to adjustment. In the
     event Tenant's examination reveals an error has been made, and Landlord
     disagrees with the results thereof, Landlord shall have 30 days to obtain
     an audit from an accountant of its choice. In the event Landlord's
     accountant and Tenant's accountant are unable to reconcile their results,
     both accountants shall mutually agree on a third accountant, whose
     determination shall be conclusive.

5.4  FINAL PRORATION. If this Lease ends on a day other than the last day of a
     calendar year, the amount of increase (if any) in the operating expenses
     payable by Tenant applicable to the calendar year in which this Lease ends
     will be calculated on the basis of the number of days of the Term falling
     within such calendar year, and Tenant's obligation to pay any increase or
     Landlord's obligation to refund any overage will survive the expiration or
     other termination of this Lease.

5.5  OTHER TAXES.

(a)  Tenant will reimburse Landlord upon demand for any and all taxes payable
     by Landlord (other than as set forth in sub-paragraph (b) below), whether
     or not now customary or within the contemplation of Landlord and Tenant:

     (1) upon or measured by rent, including without limitation, any gross
         revenue tax, sales tax, use tax, excise tax, or value added tax levied
         by the federal government or any other governmental body with respect
         to the receipt of rent; and

     (2) upon this transaction or any document to which Tenant is a party
         creating or transferring an interest or an estate in the Premises.

(b)  Tenant will not be obligated to pay any inheritance tax, gift tax,
     transfer tax, franchise tax, income tax (based on net income), profit tax,
     or capital levy imposed upon Landlord.

(c)  Tenant will pay promptly when due all personal property taxes on Tenant's
     personal property in the Premises and any other taxes payable by Tenant
     that if not paid might give rise to a lien on the Premises or Tenant's
     interest in the Premises.

5.6  ADDITIONAL RENT. Amounts payable by Tenant according to this Article 5
     will be payable as Rent, without deduction or offset. If Tenant fails to
     pay any amounts due according to this Article 5, Landlord will have all
     the rights and remedies available to it on account of Tenant's failure to
     pay Rent.

ARTICLE 6 INSURANCE

6.1  LANDLORD'S INSURANCE. At all times during the Term, Landlord will carry and
     maintain:

(a)  Fire and extended coverage insurance covering the Project, its equipment,
     common area furnishings, and


                                     Page 5
<PAGE>   8

     leasehold improvements in the Premises to the extent of the Tenant Finish
     Allowance (as that term is defined in the Workletter);

(b)  Bodily injury and property damage liability insurance; and

(c)  Such other insurance as Landlord reasonably determines from time to time.

The insurance coverages and amounts in this Section 6.1 will be reasonably
determined by Landlord.

6.2  TENANT'S INSURANCE. At all times during the Term, Tenant will carry and
     maintain, at Tenant's expense, the following insurance, in the amounts
     specified below or such other amounts as Landlord may from time to time
     reasonably request, with insurance companies and on forms satisfactory to
     Landlord;

(a)  Bodily injury and property damage liability insurance, with a combined
     single occurrence limit of not less than $3,000,000 per occurrence. All
     such insurance will be equivalent to coverage offered by a commercial
     comprehensive general liability form, including without limitation
     personal injury, products and completed operations, broad form property
     damage, and contractual liability coverage for the performance by Tenant of
     the indemnity agreements set forth in Article 21 of this Lease;

(b)  Insurance covering all of Tenant's furniture and fixtures, machinery,
     equipment, stock, and any other personal property owned and used in
     Tenant's business and found in, on, or about the Project, and any
     leasehold improvements to the Premises in excess of the Tenant Finish
     Allowance, if any, provided pursuant to the Workletter in an amount not
     less than the full replacement cost. Property forms will provide coverage
     on a broad form basis insuring against "all risks of direct physical
     loss." All policy proceeds will be used for the repair or replacement of
     the property damaged or destroyed; however, if this Lease ceases under the
     provisions of Article 18, Tenant will be entitled to any proceeds
     resulting from damage to Tenant's furniture and fixtures, machinery,
     equipment, stock, and any other personal property;

(c)  Worker's compensation insurance insuring against and satisfying Tenant's
     obligations and liabilities under the worker's compensation laws of the
     state in which the Premises are located, including employer's liability
     insurance in the limits required by the laws of the state in which the
     Project is located; and

(d)  Owned, hired, or nonowned comprehensive automobile liability at a limit of
     liability not less than $3,000,000 combined bodily injury and property
     damage per occurrence.

If Tenant fails to obtain or maintain any insurance required hereunder,
Landlord shall have the option, without assuming any obligation in connection
therewith, to effect such insurance at the sole cost of the Tenant and all
outlays by Landlord shall be reimbursed by Tenant to landlord as Additional
Rent.

6.3  FORMS OF POLICIES. Certificates of insurance, together with copies of the
     endorsements, when applicable, naming Landlord and any others specified by
     Landlord as additional insureds, will be delivered to Landlord prior to
     Tenant's occupancy of the Premises and from time to time at least 10 days
     prior to the expiration of the term of each such policy. All commercial
     general liability or comparable policies maintained by Tenant will name
     Landlord and such other persons or firms as Landlord specifies from time
     to time as additional insureds, entitling them to recover under such
     policies for any loss sustained by them, their agents, and employees,
     including those losses sustained as a result of the negligent acts or
     omissions of Tenant. All such policies maintained by Tenant will provide
     that they may not be terminated nor may coverage be reduced except after
     30 days' prior written notice to Landlord. All commercial general
     liability, automobile, and property policies maintained by Tenant will be
     written as primary policies, not contributing with and not supplemental to
     the coverage that Landlord may carry.

6.4  WAIVER OF SUBROGATION. Landlord and Tenant each waive any and all rights
     to recover against the other or against any other Tenant or occupant of
     the Project, or against the officers, directors, shareholders, partners,
     joint venturers, employees, agents, customers, invitees, or business
     visitors of such other party or of such other Tenant or occupant of the
     Project, for any loss or damage to such waiving party arising from any
     cause covered by any property insurance required to be carried by such
     party pursuant to this Article 6 or any other property insurance actually
     carried by such party to the extent of the limits of such policy. Landlord
     and Tenant from time to time will cause their respective insurers to
     issue appropriate waiver of subrogation rights endorsements to all
     property insurance policies carried in connection with the Project or the
     Premises or the contents of the Project or the Premises. Tenant agrees to
     cause all other occupants of the Premises claiming by, under, or through
     Tenant to execute and deliver to Landlord such a waiver of claims and to
     obtain such waiver of subrogation rights endorsements.

6.5  ADEQUACY OF COVERAGE. Landlord, its agents and employees make no
     representation that the limits of liability specified to be carried by
     Tenant pursuant to this Article 6 are adequate to protect Tenant. If
     Tenant believes that any of such insurance coverage is inadequate, Tenant
     shall obtain such additional insurance coverage as Tenant deems adequate,
     at Tenant's sole expense.

or permit the Premises to be used or occupied for any purpose or in any manner
prohibited by any applicable laws. Tenant will not commit waste or suffer or
permit waste to be committed in, on, or about the Premises. Tenant will conduct
its business and control its employees, agents, and invitees in such a manner as
not to create any nuisance or interfere with, annoy, or disturb any other Tenant
or occupant of the Project or Landlord in its operation of the Project. Tenant
agrees to take possession of and occupy the entire Premises no later than 60
days after the Commencement Date, and Tenant further agrees to continue to

     Landlord in writing of (1) any and all enforcement, cleanup, remedial,
     removal, or other governmental or regulatory actions instituted, completed,

     expiration or other termination of this Lease.

8.3  CERTAIN INSURANCE RISKS. Tenant will not do or permit to be done any act or

     to the Project to an amount higher than it otherwise would be for general
     office use of the Project; or (c) subject Landlord to any liability or
     responsibility for injury to any person or persons or to property by reason
     of any business or operation being carried on upon the Premises. If the

     or result in any increase in premiums for insurance carried by the
     Landlord, whether or not Landlord allows such act or omission to continue,
     Tenant shall pay any increase in premium as Additional Rent.

ARTICLE 9 ASSIGNMENT AND SUBLETTING

9.1   GENERAL.  Tenant, for itself, its heirs, distributees, executors,
      administrators, legal representatives, successors, and assigns, covenants
      and agrees that it will not assign, mortgage, or encumber this Lease, or
      sublease, nor or otherwise permit the Premises or any part of the Premises
      to be used or occupied by others, without the prior written consent of
      Landlord in each instance, which consent will not be unreasonably
      withheld. Landlord may condition its consent upon execution by the
      subtenant or assignee, as the case may be, of an instrument confirming
      the restrictions on further subleasing or assignment contained herein and
      joining in the waivers and indemnities made by Tenant hereunder. Any
      assignment or sublease in violation of this Article 9 will be void. If
      this Lease is assigned, or if the Premises or any part of the Premises are
      subleased or occupied by anyone other than Tenant, Landlord may, after any
      default by Tenant, collect rent from the assignee, subtenant, or occupant,
      and apply the net amount collected to Rent. No assignment, sublease,
      occupancy, or collection will be deemed (a) a waiver of the provisions of
      this Section 9.1; (b) the acceptance of the assignee, subtenant, or
      occupant as Tenant; or (c) a release of Tenant from the further
      performance by Tenant of covenants on the part of Tenant contained in this
      Lease. The consent by Landlord to an assignment or sublease will not be
      construed to relieve Tenant from obtaining Landlord's prior written
      consent in writing to any further assignment or sublease. No permitted
      subtenant may assign or encumber its sublease or further sublease all or
      any portion of its subleased space, or otherwise permit the subleased
      space or any part of its subleased space to be used or occupied by others,
      without Landlord's prior written consent in each instance. Any assignee
      approved by Landlord must assume all of the obligations and duties of
      Tenant under this Lease pursuant to an assumption agreement satisfactory
      to Landlord of which Landlord is the beneficiary.

9.2   SUBMISSION OF INFORMATION.  If Tenant requests Landlord's consent to a
      specific assignment or subletting, Tenant will submit in writing to
      Landlord (a) the name and address of the proposed assignee or subtenant;
      (b) the business terms of the proposed assignment or sublease; (c)
      reasonably satisfactory information as to the nature and character of the
      business of the proposed assignee or subtenant, and as to the nature of
      its proposed use of the space; (d) banking, financial, or other credit
      information reasonably sufficient to enable Landlord to determine the
      financial responsibility and character of the proposed assignee or
      subtenant; (e) the proposed form of assignment (including lease assumption
      provisions) or sublease for Landlord's reasonable approval; and (f) any
      other information reasonably required by Landlord.

9.3   PAYMENTS TO LANDLORD.  If Landlord consents to a proposed assignment or
      sublease, then Landlord will have the right to require Tenant to pay to
      Landlord a sum equal to (a) any rent or other consideration paid to Tenant
      by any proposed transferee that (after deducting the costs of Tenant, if
      any, in effecting the assignment or sublease, including reasonable
      alterations costs, commissions and legal fees) is in excess of the Rent
      allocable to the transferred space then being paid by Tenant to Landlord
      pursuant to this Lease; and (b) any other profit or gain (after deducting
      any necessary expenses incurred) realized by Tenant from any such sublease
      or assignment. All such sums owed to Landlord under 9.3(c), above will be
      payable to Landlord at the time the next payment of Monthly Rent is due.

9.4   PROHIBITED TRANSFERS.  The transfer of a majority of the issued and
      outstanding capital stock of any corporate Tenant or subtenant of this
      Lease, or a majority of the total interest in any partnership Tenant or
      subtenant, however accomplished, and whether in a single transaction or in
      a series of related or unrelated transactions, will be deemed an
      assignment of this lease or of such sublease requiring Landlord's consent
      in each instance. For purposes of this Article 9, the transfer of
      outstanding capital stock of any corporate Tenant will not include any
      sale of such stock by persons other than those deemed "insiders" within
      the meaning of the Securities Exchange Act of 1934, as amended, effected
      through the "over-the-counter market" or through any recognized stock
      exchange.

9.5   LANDLORD'S OPTIONS.  In the event of a transfer of this Lease or of all or
      any part of the Premises by Tenant, Landlord in addition to any rights
      contained herein, shall have the following options at its discretion:

      (a) to give Tenant written notice of Landlord's intention to terminate
          this Lease as to all or any portion of the Premises subject to such
          transfer on the date such notice is given or on any later date
          specified therein, whereupon, on the date specified in such notice and
          all obligations of Tenant hereunder, Tenant's right to possession of
          the Premises or such portion of the Premises shall cease and this
          Lease shall thereupon be terminated as they relate to all of any
          portion of the Premises, except as to any incompleted obligations to
          date of tenant; or

      (b) to re-enter and take possession of the Premises or the part thereof
          subject to such transfer, and to enforce all rights of Tenant, in
          accordance with such sublet or assignment of the Premises, or any part
          thereof, as if Landlord was the sublessor or assignor, and to do
          whatever Tenant is permitted to do pursuant to the terms of such
          sublease or assignment. In such event Tenant's obligations hereunder
          shall terminate regarding all or such part of the Premises.

9.6   PERMITTED TRANSFER. Landlord consents to an assignment of this Lease or
      sublease of all or part of the Premises to a wholly-owned subsidiary of
      Tenant or the parent of Tenant or to any corporation into or with which
      Tenant may be merged or consolidated; provided that (a) Tenant promptly
      provides Landlord with a fully executed copy of such assignment or
      sublease; (b) Tenant is not released from liability under this Lease

*     Lessor's consent to subsequent subletting & assignments of a sublease or
      any amendments or modifications thereto without Tenant's consent, which
      shall not be unreasonably withheld, shall relieve Tenant from this lease
      or such sublease.


                                     Page 8
<PAGE>   11
and (c) the assignee assumes in writing all of the obligations of Tenant under
this Lease.

ARTICLE 10 RULES AND REGULATIONS

Tenant and its employees, agents, licensees, and visitors will at all times
observe faithfully, and comply strictly with, the rules and regulations set
forth in Exhibit D. Landlord may from time to time reasonably amend, delete, or
modify existing rules and regulations, or adopt reasonable new rules and
regulations for the use, safety, cleanliness, and care of the Premises, the
Building, and the Project, and the comfort, quiet, and convenience of occupants
of the Project. Modifications or additions to the rules and regulations will be
effective upon 30 days' prior written notice to Tenant from Landlord. In
the event of any breach of any rules or regulations or any amendments or
additions to such rules and regulations, Landlord will have all remedies that
this Lease provides for default by Tenant, and will in addition have any
remedies available at law or in equity, including the right to enjoin any
breach of such rules and regulations. Landlord will not be liable to Tenant for
violation of such rules and regulations by any other tenant, its employees,
agents, visitors, or licensees or any other person. In the event of any conflict
between the provisions of this Lease and the rules and regulations, the
provisions of this Lease will govern.

ARTICLE 11 COMMON AREAS

As used in this Lease, the term "common areas" means, without limitation, the
entryways, stairs, driveways, roadways, parking areas, walkways, terraces,
docks, loading areas, restrooms, trash facilities, and all other areas and
facilities in the Project that are provided and designated from time to time by
Landlord for the general nonexclusive use and convenience of Tenant with
Landlord and other tenants of the Project and their respective employees,
invitees, licensees, or other visitors. Landlord grants Tenant, its employees,
invitees, licensees, and other visitors a nonexclusive license for the Term to
use the common areas in common with others entitled to use the common areas,
subject to the terms and conditions of this Lease. Without advance written
notice to Tenant, except with respect to matters covered by subsection (a)
below, and without any liability to Tenant in any respect, Landlord will have
the right to:

  (a) Close off any of the common areas to whatever extent required in the
      opinion of Landlord and its counsel to prevent a dedication of any of the
      common areas or the accrual of any rights by any person or the public to
      the common areas:

  (b) Temporarily close any of the common areas for maintenance, alteration, or
      improvement purposes; and

  (c) Change the size, use, shape, or nature of any such common areas, including
      erecting additional buildings on the common areas, expanding the existing
      Building or other buildings to cover a portion of the common areas,
      converting common areas to a portion of the Building (excluding the
      Premises) or other buildings to common areas. Upon erection of any
      additional buildings or change in common areas, the portion of the Project
      upon which buildings or other structures have been erected will no longer
      be deemed to be a part of the common areas. In the event of any such
      changes in the size or use of the Building or common areas of the Building
      or Project, Landlord will make an appropriate adjustment in the Rentable
      Area of the Building or the Building's pro rata share of exterior common
      areas of the Project, as appropriate, and a corresponding adjustment to
      Tenant's Share of the operating expenses payable pursuant to Article 5 of
      this Lease.

ARTICLE 12 LANDLORD'S SERVICES

12.1  Landlord's Repair and Maintenance. Subject to the condemnation and
      casualty provisions contained in this Lease and except as otherwise
      expressly provided herein, Landlord will maintain and repair the Premises
      and common areas of the Project, including but not limited to lobbies,
      stairs, corridors, and restrooms, the windows in the Building, the
      mechanical, plumbing and electrical equipment serving the Building, and
      the structure of the Building in reasonably good order and condition.

      the operation of low-wattage office machines (such as desktop
      micro-computers, desktop calculators, and typewriters) during Business
      Hours, although Landlord will not be obligated to furnish more power to
      the Premises than is proportionally allocated to the Premises under the
      Building design; (2) heat and air conditioning reasonably required for the
      comfortable occupation of the Premises during Business Hours; (3) access

<PAGE>   12
(b)    Tenant will have the right to purchase for use during Business Hours and
       non-Business Hours the service described in clauses (a)(1)and (2) in
       excess of the amounts Landlord has agreed to furnish so long as Tenant
       gives Landlord reasonable prior written notice of its desire to do so;
       (2) the excess services are reasonably available to Landlord and to the
       Premises; and (3) Tenant pays as Additional Rent (at the time the next
       payment of Monthly Rent is due) the cost of such excess service from
       time to time charged by Landlord; subject to the procedures established
       by Landlord from time to time for providing such additional or excess
       services.

12.3   TENANT'S COSTS. Whenever equipment or lighting (other than building
       standard lights) is used in the Premises by Tenant and such equipment or
       lighting affects the temperature otherwise normally maintained by the
       design of the Building's air conditioning system. Landlord will have the
       right, after prior written notice to Tenant, to install supplementary air
       conditioning facilities in the Premises or otherwise modify the
       ventilating and air conditioning system serving the Premises; and the
       cost of such facilities, modifications, and additional service will be
       paid by Tenant as Additional Rent. If Landlord reasonably believes that
       Tenant is using more power than Landlord furnishes pursuant to Section
       12.2, Landlord may install separate meters of Tenant's power usage, and
       Tenant will pay for the cost of excess power as Additional Rent, together
       with the cost of installing any risers, meters, or other facilities that
       may be necessary to furnish or measure such excess power to the Premises.
       Tenant's computer space will be submetered for electrical consumption.
       Submetering installation costs will be debited against Tenant's
       allowance. Tenant shall pay for excess power in this area as additional
       rent.

12.4   LIMITATION ON LIABILITY. Landlord will not be in default under this Lease
       or be liable to Tenant or any other person for direct or consequential
       damage, or otherwise, for any failure to supply any heat, air
       conditioning, elevator, cleaning, lighting, or security; for surges or
       interruptions of electricity; or for interruptions to other services
       Landlord has agreed to supply. Landlord will use reasonable efforts to
       diligently remedy any interruption in the furnishing of such services.
       Landlord reserves the right temporarily to discontinue such services at
       such times as may be necessary by reason of accident; repairs,
       alterations or improvements; strikes; lockouts; riots; acts of God;
       governmental preemption in connection with a national or local emergency;
       any rule, order, or regulation of any governmental agency; conditions of
       supply and demand that make any product unavailable; Landlord's
       compliance with any mandatory governmental energy conservation or
       environmental protection program, or any voluntary energy conservation
       program at the request of or with consent or acquiescence of Tenant; or
       any other happening beyond the control of Landlord. Landlord will not be
       liable to Tenant or any other person or entity for direct or
       consequential damages resulting from the admission to or exclusion from
       the Building or Project of any person. In the event of invasion, mob,
       riot, public excitement, strikes, lockouts, or other circumstances
       rendering such action advisable in Landlord's sole opinion, Landlord will
       have the right to prevent access to the Building or Project during the
       continuance of the same by such means as Landlord, in its sole
       discretion, may deem appropriate, including without limitation locking
       doors and closing parking areas and other common areas. Landlord will not
       be liable for damages to person or property or for injury to, or
       interruption of, business for any discontinuance permitted under this
       Article 12, nor will such discontinuance in any way be construed as an
       eviction of Tenant or cause an abatement of Rent or operate to release
       Tenant from any of Tenant's obligations under this Lease.

ARTICLE 13 TENANT'S CARE OF THE PREMISES

Tenant will not act or fail to act in a manner causing damage to the Premises
(including Tenant's equipment, personal property, and trade fixtures located in
the Premises) in their condition at the time they were delivered to Tenant,
reasonable wear and tear excluded. Tenant will immediately advise Landlord of
any damage to the Premises or the Project. All damage or injury to the Premises,
the Project, or the fixtures and appurtenances and equipment in the Premises or
the Project that is caused by Tenant, its agents, employees, or invitees and not
covered by insurance may be repaired, restored, or replaced by Landlord at the
expense of Tenant. Such expense (plus 5% of such expense for Landlord's
overhead) will be collectible as Additional Rent and will be paid by Tenant
within 10 days after delivery of a statement for such expense.

              Premises, without first obtaining Landlord's written consent. In
              no event shall the work of Tenant affect or impair the structure,

              approval of the plans, specifications, and working drawings for
              Tenant's alterations shall create no responsibility or liability
              on the part of the Landlord for their completeness, design
              sufficiency, or compliance with all laws, ordinances, rules,
              requirements, and regulations of governmental agencies or
              authorities, or the use and occupancy permit for the Building. All
              such alterations, additions, and improvements consented to by
              Landlord, and capital improvements that are required to be made to
              the Project as a result of the nature of Tenant's use of the
              Premises:

       (1)    Will be performed by contractors approved by Landlord and subject

       (2)    At Landlord's option, will be made by Landlord for Tenant's
              account, and Tenant will reimburse

     (3)  Will be done in good and workmanlike manner and shall be completed
          promptly.

     (4)  Shall not cause a loss or diminution of electric power or other

     (5)  Will be performed according to plans, specifications, and working
          drawings approved by Landlord.

     (6)  Will be in accordance with all applicable federal, state, county and
          local laws, rules, regulations, ordinances and codes.

     At all times between the start and completion of the work, in addition to
     the other policies of insurance required by this Lease, Tenant shall
     maintain a policy of "All Risk" Builder's Risk Insurance covering the
     replacement value of all work done and fixtures and equipment installed or
     to be installed at the Premises pursuant to this Article 14. Tenant
     herewith agrees to be responsible for all damages to persons or property
     including loss of life, as a result of occurrences connected with
     activities undertaken by Tenant, its agents, contractors, and employees
     pursuant hereto, and hereby indemnifies Landlord and shall defend and hold
     Landlord harmless from and against any and all loss, cost or expense in
     connection with its responsibilities hereunder.

     (b)  Subject to Tenant's rights in Article 16, all alterations, additions,
          fixtures and improvements, whether temporary or permanent in
          character, made in or upon the Premises either by Tenant or Landlord,
          will immediately become Landlord's property and at the end of the Term
          will remain on the Premises without compensation to Tenant, unless
          Landlord at the time of approval of same advises Tenant in writing
          that such alterations, additions, fixtures, or improvements must be
          removed at the expiration or other termination of this Lease.

14.2 FREE STANDING PARTITIONS. Tenant will have the right to install
     free-standing work station partitions, without Landlord's prior written
     consent, so long as no building or other governmental permit is required
     for the installation or relocation; however, if a permit is required,
     Landlord will not unreasonably withhold its consent to such relocation or
     installation. The free-standing work station partitions for which Tenant
     pays will be part of Tenant's trade fixtures for all purposes under this
     Lease. All other partitions installed in the Premises are and will be
     Landlord's property for all purposes under this Lease.

14.3 REMOVAL. If Landlord has required Tenant to remove any or all alterations,
     additions, fixtures, and improvements that are made in or upon the Premises
     pursuant to this Article 14 prior to the Expiration Date, Tenant will
     remove such alterations, additions, fixtures, and improvements at Tenant's
     sole cost and will restore the Premises to the condition in which they were
     before such alterations, additions, fixtures, improvements, and additions
     were made.

ARTICLE 15 MECHANICS' LIENS

Tenant will pay or cause to be paid all costs and charges for work (a) done by
Tenant or caused to be done by Tenant, in or to the Premises, and (b) for all
materials furnished for or in connection with such work. Tenant will indemnify
Landlord against and defend and hold Landlord, the Premises and the Project
free, clear, and harmless of and from all mechanics' liens and claims of liens,
and all other liabilities, liens, claims and demands on account of such work by
or on behalf of Tenant, other than work performed by Landlord pursuant to the
Workletter. If any such lien, at any time, is filed against the Premises or any
part of the Project, Tenant will cause such lien to be discharged of record
within 10 days after the filing of such lien, except that if Tenant desires to
contest such lien, it will furnish Landlord, within such 10-day period, security
reasonably satisfactory to Landlord of at least 150% of the amount of the claim,
plus estimated costs and interest, or comply with such statutory procedures as
may be available to release the lien. If a final judgment establishing the
validity or existence of a lien for any amount is entered, Tenant will pay and
satisfy the same at once. If Tenant fails to pay any charge for which a
mechanics' lien has been filed, and has not given Landlord security as described
above, or has not complied with such statutory procedures as may be available to
release the lien, Landlord may, at its option, pay such charge and related costs
and interest, and the amount so paid, together with reasonable attorneys' fees
incurred in connection with such lien, will be immediately due from Tenant to
Landlord as Additional Rent. Nothing contained in this Lease will be deemed the
consent or agreement of Landlord to subject Landlord's interest in the Project
to liability under any mechanics' or other lien law. If Tenant receives written
notice that a lien has been or is about to be filed against the Premises or the
Project, or that any action affecting title to the Project has been commenced on
account of work done by or for or materials furnished to or for Tenant, it will
immediately give Landlord written notice of such notice. At least 15 days prior
to the commencement of any work (including but not limited to any maintenance,
repairs, alterations, additions, improvements, or installations) in or to the
Premises, by or for Tenant, Tenant will give Landlord written notice of the
proposed work and the names and addresses of the persons supplying labor and
materials for the proposed work. Landlord will have the right to post notices of
nonresponsibility or similar written notices on the Premises in order to protect
the Premises against any such liens.

ARTICLE 16 END OF TERM

At the end of this Lease, Tenant will promptly quit and surrender the Premises
broom-clean, in good order and repair, ordinary wear and tear excepted and
deliver all keys to the Premises and the Building to Landlord. Tenant is not
then in default, Tenant may remove from the Premises any trade fixtures,
equipment, and movable furniture placed in the Premises by Tenant, whether or
not such trade fixtures or equipment are fastened to the Building; Tenant will
not remove any trade fixtures or equipment without Landlord's prior written
consent if such fixtures or equipment are used in the operation of the
Building, or if the removal of such fixtures or equipment will result in
impairing the structural strength of the Building. Whether or not Tenant is in
default, Tenant will remove such alterations, additions, improvements, trade
fixtures, equipment, and furniture as Landlord has requested in accordance with
Article 14. Tenant will fully repair any damage occasioned by the removal of
any trade fixtures, equipment, furniture, alterations, additions, and
improvements. All trade fixtures, equipment, furniture, inventory, effects,
alterations, additions, and improvements on the Premises after the end of the
Term will be deemed conclusively to have been abandoned and may be
appropriated, sold, stored, destroyed, or otherwise disposed of by Landlord
without notice to Tenant or any other person and without obligation to account
for them. Tenant will pay Landlord for all expenses incurred in connection with
the removal of such property including but not limited to the cost of storage,
and the cost of repairing any damage to the Building or Premises caused by the
removal of such property. Tenant's obligation to observe and perform this
covenant will survive the expiration or other termination of this Lease.

ARTICLE 17 EMINENT DOMAIN

If all of the Premises are taken by exercise of the power of eminent domain (or
conveyed by Landlord in lieu of such exercise) this Lease will terminate on a
date (the "termination date") which is the earlier of the date upon which the
condemning authority takes possession of the Premises or the date on which
title to the Premises is vested in the condemning authority. If more than 25%
of the Rentable Area of the Premises is so taken, Tenant will have the right to
cancel this Lease by written notice to Landlord given within 20 days after the
termination date. If less than 25% of the Rentable Area of the Premises is so
taken, or if the Tenant does not cancel this Lease according to the preceding
sentence, the Monthly Rent will be abated in the proportion of the Rentable
Area of the Premises so taken to the Rentable Area of the Premises immediately
before such taking, and Tenant's Share will be appropriately recalculated. If
25% or more of the Building or the Project is so taken, Landlord may cancel
this Lease by written notice to Tenant given within 30 days after the
termination date. In the event of any such taking, the entire award will be
paid to Landlord, and Tenant will have no right or claim to any part of such
award; however, Tenant will have the right to assert a claim against the
condemning authority in a such or separate action, so long as Landlord's award
is not reduced as a consequence of such claim, for Tenant's costs including but
not limited to relocating expenses and trade fixtures owned by Tenant.

ARTICLE 18 DAMAGE AND DESTRUCTION

(a)  If the Premises or the Building is damaged by fire or other insured
     casualty, Landlord will give Tenant written notice of the time which will
     be needed to repair such damage, as determined by Landlord in its
     reasonable discretion, and the election (if any) which Landlord has made
     according to this Article 18. Such notice will be given before the 30th day
     (the "notice date") after the fire or other insured casualty.

(b)  If the Premises or the Building is damaged by fire or other insured
     casualty to an extent which may be repaired within 180 days after the
     notice date, as reasonably determined by Landlord, Landlord will promptly
     begin to repair the damage after the notice date and will diligently pursue
     the completion of such repair. In that event this Lease will continue in
     full force and effect except that Monthly Rent will be abated on a pro rata
     basis from the date of the damage until the date of the completion of such
     repairs (the "repair period") based on the proportion of the Rentable Area
     of the Premises Tenant is unable to use during the repair period.

(c)  If the Premises or the Building is damaged by fire or other insured
     casualty to an extent that may not be repaired within 180 days after the
     notice date, as reasonably determined by Landlord, then (1) Landlord may
     cancel this Lease as of the date of such damage by written notice given to
     Tenant on or before the notice date or (2) Tenant may cancel this Lease as
     of the date of such damage by written notice given to Landlord within 10
     days after Landlord's delivery of a written notice that the repairs cannot
     be made within such 180 day period. If neither Landlord nor Tenant so
     elects to cancel this Lease, Landlord will diligently proceed to repair the
     Building and Premises and Monthly Rent will be abated on a pro rata basis
     during the repair period based on the proportion of the Rentable Area of
     the Premises Tenant is unable to use during the repair period.

(d)  Notwithstanding the provisions of subparagraphs (a), (b), and (c) above, if
     the Premises or the Building or the Project are damaged by uninsured
     casualty, or if the proceeds of insurance are insufficient to pay for the
     repair of any damage to the Premises or the Building or the Project,
     Landlord will have the option to repair such damage or cancel this Lease as
     of the date of such casualty by written notice to Tenant on or before the
     notice date.


                                    Page 12
<PAGE>   15
     (e)  If any such damage by fire or other casualty is the result of the
          willful conduct or negligence or failure or act of Tenant, its agents,
          contractors, employees, or invitees, there will be no abatement of
          Monthly Rent as otherwise provided for in this Article 18. Tenant will
          have no rights to terminate this Lease on account of any damage to the
          Premises, the Building, or the Project, except as set forth in this
          Lease.

     (f)  For purposes of this Article 18 and subject to subsections (a) thru
          (e) hereof, Landlord shall repair or restore any portion of the
          alterations, additions or improvements in the Premises or the
          decorations thereto to the extent that such alterations, additions,
          improvements and decorations were provided by Landlord at the
          beginning of the Term. Landlord shall have no further obligations
          pursuant to this Lease to repair or restore any alterations, additions
          or improvements in the Premises or the decorations thereto. If Tenant
          desires any other or additional repairs or restoration and if Landlord
          consents thereto, the same shall be done at Tenant's sole cost and
          expense. Tenant acknowledges that Landlord shall be entitled to the
          full proceeds of any insurance coverage, whether carried by Landlord
          or Tenant, to the extent of damage to alterations, additions,
          improvements or decorations.

ARTICLE 19 SUBORDINATION

19.1 GENERAL. This Lease and Tenant's rights under this Lease are subject and
     subordinate to any ground or underlying lease, mortgage, indenture, deed of
     trust, or other lien encumbrance (each a "superior lien"), together with
     any renewals, extensions, modifications, consolidations, and replacements
     of such superior lien, now or in the future affecting or placed, charged,
     or enforced against the Land, the Building, or all or any portion of the
     Project or any interest of Landlord in them or Landlord's interest in this
     Lease and the leasehold estate created by this Lease (except to the
     extent any such instrument expressly provides that this Lease is superior
     to such instrument). Notwithstanding the foregoing, Tenant will execute,
     acknowledge, and deliver to Landlord, within 20 days after written demand
     by Landlord, such documents as may be reasonably requested by Landlord or
     the holder of any superior lien to confirm or effect any such subordination
     or superiority, as applicable.*

19.2 ATTORNMENT. Tenant agrees that in the event that any holder of a superior
     lien succeeds to Landlord's interest in the Premises, Tenant will pay to
     such holder all Rent subsequently payable under this Lease. Further, Tenant
     agrees that in the event of the enforcement by the holder of a superior
     lien of the remedies provided for by law or by such superior lien, Tenant
     will, upon request of any person or party succeeding to the interest of
     Landlord as a result of such enforcement, automatically become the Tenant
     of and attorn to such successor in interest without change in the terms or
     provisions of this Lease. Such successor in interest will not be bound by;


 (a) Any payment of Rent for more than one month in advance, except prepayments
     in the nature of security for the performance by Tenant of its obligations
     under this Lease that are actually received by such successor in interest;

 (b) Any amendment or modification of this Lease made without the written
     consent of such successor in interest (if such consent was required under
     the terms of such superior lien);

 (c) Any claim against Landlord arising prior to the date on which such
     successor in interest succeeded to Landlord's interest; or

 (d) Any claim or offset of Rent against the Landlord.

     Upon request by such successor in interest, Tenant will, within 20 days
     after written demand, execute, acknowledge, and deliver an instrument or
     instruments confirming the attornment.

ARTICLE 20 ENTRY BY LANDLORD

Landlord, its agents, employees, and contractors may enter the Premises at any
time in response to an emergency and at any other reasonable time to:

 (a) Inspect the Premises;

 (b) Exhibit the Premises to prospective purchasers, lenders, or tenants;

 (c) Determine whether Tenant is complying with all its obligations in this
     Lease;

  *  So long as the Owner & holder of such superior lien agrees not
     to disturb Tenant's right to possession, so long as Tenant is not in
     default, after applicable notice and period for cure.


                                    Page 13

     (d)  Supply cleaning service and any other service to be provided by
          Landlord to Tenant according to the Lease;

     (e)  Post written notices of nonresponsibility or similar notices; or

     (f)  Make repairs required of Landlord under the terms of this Lease or
          make repairs to any adjoining space or utility services or make
          repairs, alterations, or improvements to any other portion of the
          Building.

Tenant, by this Article 20, waives any claim against Landlord, its agents,
employees, or contractors for damage for any injury or inconvenience to or
interference with Tenant's business, any loss of occupancy or quiet enjoyment
of the Premises, or any other loss occasioned by any entry in accordance with
this Article 20. Landlord will at all times have and retain a key with which to
unlock all of the doors in, on, or about the Premises (excluding Tenant's
vaults, safes, and similar areas designated in writing by Tenant in advance).
Landlord will have the right to use any and all means Landlord may deem proper
to open doors in and to the Premises in an emergency in order to obtain entry
to the Premises, provided that Landlord will promptly repair any damages caused
by any forced entry. Any entry to the Premises by Landlord in accordance with
this Article 20 will not be construed or deemed to be a forcible or unlawful
entry into or a detainer of the Premises or an eviction, actual or
constructive, of Tenant from the Premises or any portion of the Premises, nor
will any such entry entitle Tenant to damages or an abatement of Monthly Rent,
Additional Rent, or other charges that this Lease requires Tenant to pay.

ARTICLE 21 INDEMNIFICATION, WAIVER, AND RELEASE

21.1 INDEMNIFICATION. To the extent not prohibited by law, Landlord, its
     employees and agents shall not be liable for damage to person, property or
     business or resulting from the loss of use thereof sustained by Tenant or
     other persons due to the Building or any part thereof becoming out of
     repair or due to an accident or due to any act or neglect of any tenant,
     occupant or other person.* Tenant further agrees that all personal property
     upon the Premises, loading dock, holding areas, and freight elevators shall
     be at the sole risk of Tenant. Tenant will neither hold nor attempt to hold
     Landlord, its employees, or agents liable for, and Tenant will indemnify
     and defend and hold harmless Landlord, its employees, and agents from and
     against, any and all demands, claims, causes of action, fines, penalties,
     damages (including consequential damages), liabilities, judgments, and
     expenses (including without limitation reasonable attorneys' fees) incurred
     in connection with or arising from:* unless as a result of Landlord's
     intentional act or omissions.

     (a)  the use or occupancy or manner of use or occupancy of the Premises or
          any common areas by Tenant or any person claiming under Tenant;

     (b)  any activity, work, or thing done or permitted by Tenant in or about
          the Premises, the Building, or the Project;

     (c)  any breach by Tenant or its employees, agents, contractors, or
          invitees of this Lease; and

     (d)  any injury or damage to the person, property, or business of Tenant,
          its employees, agents, contractors, or invitees entering upon the
          Premises under the express or implied invitation of Tenant.

     If any action or proceeding is brought against Landlord, its employees, or
     agents by reason of any such claim for which Tenant has indemnified
     Landlord, Tenant, upon written notice from Landlord, will defend the same
     at Tenant's expense, with counsel reasonably satisfactory to Landlord.

21.2 WAIVER AND RELEASE. Tenant, as a material part of the consideration to
     Landlord for this Lease, by this Section 21.2 waives and releases all
     claims against Landlord, its employees, and agents with respect to all
     matters for which Landlord has disclaimed liability pursuant to the
     provisions of this Lease.

ARTICLE 22 SECURITY DEPOSIT There will be no security deposit




                                    Page 14

<PAGE>   17
ARTICLE 23 QUIET ENJOYMENT

Landlord covenants and agrees with Tenant (that so long as Tenant pays the Rent
and observes and performs all the terms, covenants and conditions of this Lease
on Tenant's part to be observed and performed, Tenant may peaceably and quietly
enjoy the Premises subject, nevertheless, to the terms and conditions of this
Lease, and Tenant's possession will not be disturbed by anyone claiming by,
through, or under Landlord.

ARTICLE 24 EFFECT OF SALE

A sale, conveyance, or assignment of the Building or the Project will operate to
release Landlord from liability from and after the effective date of such sale,
conveyance, or assignment upon all of the covenants, terms, and conditions of
this Lease, express or implied, except those liabilities that arose prior to
such effective date, and after the effective date of such sale, conveyance, or
assignment. Tenant will look solely to Landlord's successor in interest in and
to this Lease. This Lease will not be affected by any such sale, conveyance or
assignment and Tenant will attorn to Landlord's successor in interest to this
Lease from and after such effective date.

ARTICLE 25 DEFAULT

      "events of default" or, individually as an "event of default":

      (a)  Tenant fails to pay any Rent or other monetary obligation when due,
           and such failure continues for 5 days after written notice from
           Landlord; however, Tenant will not be entitled to more than 1 written
           notice for monetary defaults during any 12-month period, and if after
           such written notice any Rent is not paid when due, an event of
           default will be considered to have occurred without further notice;

      (b)  Tenant vacates or abandons the Premises;

      (c)  This Lease or the Premises or any part of the Premises is taken upon
           execution or by other process of law directed against Tenant, or is

      (d)  Tenant or any guarantor of Tenant's obligations under this Lease

           material allegations of any such petition by answer or otherwise, or
           admits in writing its inability to meet its debts as they mature, or
           is dissolved or makes an assignment for the benefit of creditors;

      (e)  Involuntary proceedings under any such bankruptcy law or insolvency
           act or for the dissolution of Tenant or any Guarantor are instituted

           appointment;

      (f)  Tenant fails to take possession of the Premises on the Commencement

      (g)  Tenant violates the terms of Article 9 "Assignment and Subletting";

           conditions that this Lease requires Tenant to perform, and such
           breach continues for a period of 30 days after written notice from
           Landlord to Tenant or, if such breach cannot be cured reasonably
           within such 30-day period, if Tenant fails to diligently commence to
           cure such breach within 30 days after written notice from Landlord
           and to complete such cure within a reasonable time thereafter; or

25.2  LANDLORD REMEDIES. If any one or more events of default set forth in
      Section 25.1 occurs then Landlord has the right, at its election:

      (a)  To give Tenant written notice of Landlord's intention to terminate
           this Lease on the earliest date permitted by law or on any later date
           specified in such notice, in which case Tenant's right to possession
           of the Premises will cease and this Lease will be terminated, except
           as to Tenant's liability, as if the expiration




                                    Page 15








<PAGE>   18
            of the term fixed in such notice were the end of the Term;

      (b)   Without further demand or notice, and without terminating this
            Lease, to reenter and take possession of the Premises or any part of
            the Premises, repossess the same, expel Tenant and those claiming
            through under Tenant, and remove the effects of both or either,
            using such force for such purposes as may be necessary, without
            being liable for prosecution, without being deemed guilty of any
            manner of trespass and without prejudice to any remedies for arrears
            of Monthly Rent or other amounts payable under the Lease or as a
            result of any preceding breach of covenants or conditions; or

      (c)   Without further demand or notice to cure any event of default and to
            charge Tenant for the cost of effecting such cure, including without
            limitation reasonable attorneys' fees and interest on the amount so
            advanced at the rate set forth in Section 27.21, provided that
            Landlord will have no obligation to cure any such event of default
            of Tenant.

      Should Landlord elect to reenter as provided in subsection (b), or should
      Landlord take possession pursuant to legal proceedings or pursuant to any
      notice provided by law, Landlord may, from time to time, without
      terminating this Lease, relet the Premises or any part of the Premises in
      Landlord's or Tenant's name, but for the account of Tenant, for such
      term or terms (which may be greater or less than the period which would
      otherwise have constituted the balance of the Term) and on such
      conditions and upon such other terms (which may include concessions of
      free rent and alteration and repair of the Premises) as Landlord, in its
      reasonable discretion, may determine, and Landlord may collect and
      receive the rents from such reletting. Landlord will in no way be
      responsible or liable for any failure to relet the Premises, or any part
      of the Premises, or for any failure to collect any rent due upon such
      reletting. No such reentry or taking possession of the Premises by
      Landlord will be construed as an election on Landlord's part to terminate
      this Lease unless a written notice of such intention is given to Tenant.
      No written notice from Landlord under this Section or under a forcible or
      unlawful entry and detainer statute or similar law will constitute an
      election by Landlord to terminate this Lease unless such notice
      specifically so states. Landlord reserves the right following any such
      reentry or reletting to exercise its right to terminate this Lease by
      giving Tenant such written notice, in which event this Lease will
      terminate as specified in such notice.

25.3  CERTAIN DAMAGES. In the event that Landlord does not elect to terminate
      this Lease as permitted in Section 25.2(a), but on the contrary elects to
      take possession as provided in Section 25.2(b), Tenant will pay to
      Landlord Monthly Rent and other sums as provided in this Lease that would
      be payable under this Lease if such repossession had not occurred, less
      the net proceeds, if any, of any reletting of the Premises after
      deducting all of Landlord's reasonable expenses in connection with such
      reletting, including without limitation all repossession costs, brokerage
      commissions, attorneys' fees, expenses of employees, alteration and
      repair costs, and expenses of preparation for such reletting. Tenant will
      pay such Rent and other sums to Landlord monthly on the day on which the
      Monthly Rent would have been payable under this Lease if possession had
      not been retaken, and Landlord will be entitled to receive such Rent and
      other sums from Tenant on each such day.

25.4  CONTINUING LIABILITY AFTER TERMINATION. If this Lease is terminated on
      account of the occurrence of an event of default, Tenant will remain
      liable to Landlord for damages in an amount equal to the Rent and other
      amounts that would have been owing by Tenant for the balance of the Term,
      had this Lease not been terminated, less the net proceeds, if any, of any
      reletting of the Premises by Landlord subsequent to such termination,
      after deducting all of Landlord's expenses in connection with such
      reletting, including without limitation the expenses enumerated in
      Section 25.3. Landlord will be entitled to collect such damages from
      Tenant monthly on the day on which Monthly Rent and other amounts would
      have been payable under this Lease if this Lease had not been terminated,
      and Landlord will be entitled to receive such Monthly Rent and other
      amounts from Tenant on each such day. Alternatively, at the option of
      Landlord, in the event this Lease is so terminated, Landlord will be
      entitled to recover against Tenant as damages for loss of the bargain and
      not as a penalty:

      (a)   The worth at the time of award of the unpaid Rent that had been
            earned at the time of termination;

      (b)   The worth at the time of award of the amount by which the unpaid
            Rent that would have been earned after termination until the time
            of award exceeds the amount of such rental loss that Tenant proves
            could have been reasonably avoided;

      (c)   The worth at the time of award of the amount by which the unpaid
            Rent for the balance of the Term of this Lease (had the same not
            been so terminated by Landlord) after the time of award exceeds the
            amount of such rental loss that Tenant proves could be reasonably
            avoided;

      (d)   Any other amount necessary to compensate Landlord for all the
            detriment proximately caused by Tenant's failure to perform its
            obligation under this Lease or which in the ordinary course of
            things would be likely to result therefrom.

      The "worth at the time of award" of the amounts referred to in clauses
      (a) and (b) above is computed by



                                    Page 16
<PAGE>   19
     adding interest at the per annum interest rate described in Section 27.21
     on the date on which this Lease terminated from the date of termination
     until the time of the award. The "worth at the time of award" of the amount
     referred to in clause (c) above is computed by discounting such amount at
     the discount rate of the Federal Reserve Bank of New York, New York, at the
     time of award plus 1%.

25.5 CUMULATIVE REMEDIES. Any suit or suits for the recovery of the amounts and
     damages set forth in Sections 25.3 and 25.4 may be brought by Landlord,
     from time to time, at Landlord's election, and nothing in the Lease will
     be deemed to require Landlord to await the date upon which this Lease or
     the Term would have expired had there occurred no event of default. Each
     right and remedy provided for in this Lease is cumulative and is in
     addition to every other right or remedy provided for in this Lease or now
     or after the Lease Date existing at law or in equity or by statute or
     otherwise, and the exercise or beginning of the exercise by Landlord of any
     one or more of the rights or remedies provided for in this Lease or now or
     after the Lease Date existing at law or in equity or by statute or
     otherwise will not preclude the simultaneous or later exercise by Landlord
     of any or all other rights or remedies provided for in this Lease or now or
     after the Lease Date existing at law or in equity or by statute or
     otherwise. All costs incurred by Landlord in collecting any amounts and
     damages owing by Tenant pursuant to the provisions of this Lease or to
     enforce any provisions of this Lease, including reasonable attorneys' fees
     from the date any such matter is turned over to any attorney, whether or
     not one or more actions are commenced by Landlord, will also be recoverable
     by Landlord from Tenant. Notwithstanding the foregoing, Landlord waives any
     right, whether statutory or otherwise, to a lien against Tenant's personal
     property.

25.6 WAIVER OF REDEMPTION. Tenant waives any right of redemption arising as a
     result of Landlord's exercise of its remedies under this Article 25.

ARTICLE 26  PARKING

Tenant will be entitled to use the parking spaces at the Premises and at 2309
Renard Place, SE and The Hampton Inn site during the Term subject to the rules
and regulations set forth in Exhibit D, and any amendments or additions to
them.

Neither Landlord nor any operator of the parking areas within the Project, as
the same are designated and modified by Landlord, in its sole discretion, from
time to time (the "parking areas") will be liable for loss of or damage to any
vehicle or any contents of such vehicle or accessories to any such vehicle, or
any property left in any of the parking areas, resulting from fire, theft,
vandalism, accident, conduct or other users of the parking areas and other
persons, or any other casualty or cause. Further, Tenant understands and agrees
that: (a) Landlord will not be obligated to provide any traffic control,
security protection or operator for the parking areas; (b) Tenant uses the
parking areas at its own risk; and (c) Landlord will not be liable for personal
injury or death, or theft, loss of, or damage to property. Tenant waives and
releases Landlord from any and all liability arising out of the use of the
parking areas by Tenant, its employees, agents, invitees, and visitors, whether
brought by any of such persons or any other person.

Tenant's right to use the parking areas will be in common with other tenants of
the Project and 2309 Renard, The Hampton Inn with other parties permitted by
Landlord to use the parking areas. Landlord has granted Brown & Root the right
to park up to 12 vehicles at the far East section of the parking lot. Landlord
will designate five (5) visitors spaces directly in front of the building entry
at 2309 Renard Place, SE. Landlord will not be liable to Tenant for any
unavailability of Tenant's designated spaces, if any, nor will any
unavailability entitle Tenant to any refund, deduction, or allowance. Tenant
will not park in any numbered space or any space designated as: HANDICAPPED,
VISITORS ONLY, LIMITED TIME PARKING (or similar designation). If the parking
areas are damaged or destroyed, or if the use of the parking areas is limited or
prohibited by any governmental authority, or the use or operation of the parking
areas is limited or prevented by strikes or other labor difficulties or other
causes beyond Landlord's control, Tenant's inability to use the parking spaces
will not subject Landlord or any operator of the parking areas to any liability
to Tenant and will not relieve Tenant of any of its obligations under the Lease
and the Lease will remain in full force and effect.

Tenant has no right to assign or sublicense any of its rights in the parking
spaces, except at part of a permitted assignment or sublease of the Lease.

ARTICLE 27  MISCELLANEOUS

27.1 NO OFFER. Submission of the Lease to Tenant is for examination and shall
     not bind Landlord in any manner. No lease or obligations of Landlord shall
     arise until this instrument is signed by both Landlord and Tenant and
     delivery is made to each; provided, however, the execution and delivery by
     Tenant of this Lease to Landlord or Landlord's agent shall constitute an
     irrevocable offer by Tenant to lease the Premises on the terms and
     conditions herein contained, which offer may not be withdrawn or revoked
     for 15 days after such execution and delivery.


                                    Page 17



<PAGE>   20
27.2  JOINT AND SEVERAL LIABILITY. If Tenant is composed of more than one
      signatory in this Lease, each signatory will be jointly and severally
      liable with each other signatory for payment and performance according to
      this Lease. The act of, written notice to, written notice from, refund to,
      or signature of a signatory to this Lease (including without limitation
      modifications of this Lease made by fewer than all such signatories) will
      bind every other signatory as though every other signatory had so acted,
      or received or given the written notice or refund, or signed.

27.3  NO CONSTRUCTION AGAINST DRAFTING PARTY. Landlord and Tenant acknowledge
      that each of them and the counsel have had an opportunity to review this
      Lease and that this Lease will not be construed against Landlord merely
      because Landlord has prepared it.

27.4  TIME OF THE ESSENCE. Time is of the essence of each and every provision of
      this Lease.

27.5  NO RECORDATION. Tenant's recordation of this Lease or any memorandum or
      short form of it will be void and an event of default under this Lease.
      Tenant shall, at the request of Landlord, execute a short-form lease and
      have it properly acknowledged for the purpose of recording. The cost of
      recording such short form lease shall be borne by Landlord.

27.6  NO WAIVER. No waiver by Landlord of any agreement, condition or provision
      contained in this Lease will be valid or binding unless expressed in
      writing and signed by Landlord. The waiver by Landlord of any agreement,
      condition, or provision contained in this Lease will not be deemed to be a
      waiver of any subsequent breach of the same or any other agreement,
      condition, or provision contained in this Lease, nor will any custom or
      practice that may grow up between the parties in the administration of the
      terms of this Lease be construed to waive or to lessen the right of
      Landlord to insist upon the performance by Tenant in strict accordance
      with the terms of this Lease. The subsequent acceptance of Rent by
      Landlord will not be deemed to be a waiver of any preceding breach by
      Tenant of any agreement, condition, or provision of this Lease, other than
      the failure of Tenant to pay the particular Rent so accepted, regardless
      of Landlord's knowledge of such preceding breach at the time of acceptance
      of such Rent.

27.7  LIMITATION ON RECOURSE. Tenant specifically agrees to look solely to
      Landlord's interest in the Project for the recovery of any judgments from
      Landlord. It is agreed that Landlord (and its agents, shareholders,
      venturers, and partners, and their shareholders, venturers, and partners
      and all of their officers, directors, and employees) will not be
      personally liable for any such judgments.

27.8  ESTOPPEL CERTIFICATES. At any time and from time to time but within 15
      days after prior written request by Landlord, Tenant will execute,
      acknowledge, and deliver to Landlord or such other person as Landlord
      shall direct, promptly upon request, a certificate in a form
      substantially similar to a form provided by Landlord certifying (a) that
      this Lease is unmodified and in full force and effect or, if there have
      been modifications, that this Lease is in full force and effect, as
      modified, and stating the date and nature of each modification; (b) the
      date, if any, to which Rent and other sums payable under this Lease have
      been paid; (c) that no written notice of any default has been delivered to
      Landlord which default has not been cured, except as to defaults specified
      in said certificate; (d) that the Tenant has no knowledge of and that
      there is no event of default under this Lease or any event which, with
      notice or the passage of time, or both, would result in an event of
      default under this Lease, except for defaults specified in said
      certificate; and (e) such other matters as may be reasonably requested by
      Landlord. Any such certificate may be relied upon by any prospective
      purchaser or existing or prospective mortgagee or beneficiary under any
      deed of trust of the Building or any part of the project. Tenant's failure
      to deliver such a certificate within such time will be conclusive
      evidence of the matters set forth in it, and such failure shall be an
      event of default.

27.9  ATTORNEYS' FEES. If Landlord and Tenant litigate any provision of this
      Lease or the subject matter of this Lease, the unsuccessful litigant will
      pay to the successful litigant all costs and expenses, including
      reasonable attorneys' fees and court costs, incurred by the successful
      litigant at trial and on any appeal. If, without fault, either Landlord or
      Tenant is made a party to any litigation instituted by or against the
      other, the other will indemnify the faultless one against all loss,
      liability, and expense, including reasonable attorneys' fees and court
      costs, incurred in connection with such litigation.

27.10 NO MERGER. The voluntary or other surrender of this Lease by Tenant or
      the cancellation of this Lease by mutual agreement of Tenant and Landlord
      or the termination of this Lease on account of Tenant's default will not
      work a merger, and will, at Landlord's option, (a) terminate all or any
      sublease and subtenancies or (b) operate as an assignment to Landlord of
      all or any subleases or subtenancies. Landlord's option under this Section
      27.10 will be exercised by written notice to Tenant and all known
      sublessees or subtenants in the Premises or any part of the Premises.

27.11 HOLDING OVER. Tenant will have no right to remain in possession of all or
      any part of the Premises after the expiration of the Terms and the Renewal
      Term, if Tenant renews the Lease as provided herein and Landlord may, at
      its option, re-enter and take possession of the Premises, reserving its
      rights to collect damages sustained by reason of Tenant's unlawful
      retention of possession of the Premises or any part thereof. If Tenant
      remains in possession of all or any part of the Premises after the
      expiration of the Term, with the express written consent of Landlord: (a)
      such tenancy will be deemed

                                    Page 18
<PAGE>   21
          to be a periodic tenancy from month-to-month only; (b) such tenancy
          will not constitute a renewal extension of this Lease for any further
          term; and (c) such tenancy may be terminated by Landlord upon the
          earlier of 30 days' prior written notice or the earliest date
          permitted by law. In such event, Monthly Rent will be increased to an
          amount equal to 140% of the Monthly Rent payable during the last month
          of the Term, and any other sums due under this Lease will be payable
          in the amount and at the time specified in this Lease. During such
          month-to-month tenancy, Tenant will observe every other term,
          condition, and covenant contained in this Lease.

27.12     NOTICES. Any notice, request, demand, consent, approval, or other
          communication required or permitted under this Lease must be in
          writing and will be deemed to have been given when personally
          delivered, sent by facsimile with delivery acknowledged by the sending
          machine, deposited with any nationally recognized overnight carrier
          that routinely issues receipts, or deposited in any depository
          regularly maintained by the United States Postal Service, postage
          prepaid, certified mail, return receipt requested, addressed to the
          party for whom it is intended at its address(es) set forth in Section
          1.1. Either Landlord or Tenant may add additional addresses or change
          its address for purposes of receipt of any such communication by
          giving [illegible] days' prior written notice of such change to the
          other party in the manner prescribed in this Section 27.12.

27.13     SEVERABILITY. If any provision of this Lease proves to be illegal,
          invalid, or unenforceable, the remainder of this Lease will not be
          affected by such finding, and in lieu of each provision of this Lease
          that is illegal, invalid, or unenforceable a provision shall be deemed
          added as a part of this Lease as similar in terms to such
          illegal, invalid, or unenforceable provision as may be possible and be
          legal, valid, and enforceable.

27.14     WRITTEN AMENDMENT REQUIRED. No amendment, alteration, modification of,
          or addition to the Lease will be valid or binding unless expressed in
          writing and signed by Landlord and Tenant. Tenant agrees to make any
          modifications of the terms and provisions of this Lease required or
          requested by any lending institution providing financing for the
          Building, or Project, as the case may be, provided that no such
          modifications will materially adversely affect Tenant's rights and
          obligations under this Lease.

27.15     ENTIRE AGREEMENT. This Lease, the exhibits and addenda, if any,
          contain the entire agreement between Landlord and Tenant. No promises
          or representations, except as contained in this Lease, have been made
          to Tenant respecting the condition or the manner of operating the
          Premises, the Building, or the Project.

27.16     CAPTIONS. The captions of the various articles and sections of this
          Lease are for convenience only and do not necessarily define, limit,
          describe, or construe the contents of such articles or sections.

27.17     NOTICE OF LANDLORD'S DEFAULT. In the event of any alleged default in
          the obligation of Landlord under this Lease, Tenant will deliver to
          Landlord written notice listing the reasons for Landlord's default and
          Landlord will have 30 days following receipt of such notice to cure
          such alleged default or, in the event the alleged default cannot
          reasonably be cured within a 30-day period, to commence action and
          proceed diligently to cure such alleged default. A copy of such notice
          to Landlord will be sent to any holder of a mortgage or other
          encumbrance on the Building or Project of which Tenant has been
          notified in writing, and any such holder will also have an additional
          like period to cure such alleged default.

27.18     AUTHORITY. Tenant and the party executing this Lease on behalf of
          Tenant represent to Landlord that such party is authorized to do so by
          requisite action of the board of directors or partners, as the case
          may be, and agree upon request to deliver to Landlord a resolution or
          similar document to that effect.

27.19     BROKERS. Landlord and Tenant represent and warrant that they have not
          consulted or negotiated with any broker, finder or agent with regard
          to the Premises except the broker(s) named in Section 1.1. Each agrees
          to hold the other harmless and indemnify the other against all costs,
          expenses, attorney's fees, or other liability for commissions or other
          compensation or charges claimed by any broker, finder or agent
          claiming the same by, through or under it and such indemnity shall
          survive the expiration or earlier termination of this Lease.

27.20     GOVERNING LAW. This Lease will be governed by and construed pursuant
          to the laws of the state in which the Project is located.

27.21     LATE PAYMENTS. Any Rent or other monetary obligation due Landlord that
          is not paid within 10 days when due will accrue interest at a rate of
          the Prime Rate plus 5% per annum (but in no event in an amount in
          excess of the maximum rate allowed by applicable law) from the date on
          which it was due until the date on which it is paid in full with
          accrued interest. In addition to the foregoing, Tenant shall pay to
          Landlord a late charge of 5% of the amount due.

27.22     NO EASEMENTS FOR AIR OR LIGHT. Any diminution or shutting off of
          light, air, or view by any structure that may be erected on lands
          adjacent to the Building will in no way affect this Lease or impose
          any liability on Landlord.

27.23     TAX CREDITS. Landlord is entitled to claim all tax credits and
          depreciation attributable to leasehold


                                    Page 19

<PAGE>   22
       improvements in the Premises. Promptly after Landlord's demand, Landlord
       and Tenant will prepare a detailed list of the leasehold improvements and
       fixtures and their respective costs for which Landlord Tenant has paid.
       Landlord will be entitled to all credits and depreciation for those items
       for which Landlord has paid by means of any Tenant finish allowances or
       otherwise. Tenant will be entitled to any tax credit and depreciation for
       all items for which Tenant has paid with funds not provided by Landlord.

27.24

27.25  FINANCIAL REPORTS. Within 15 days after Landlord's request, Tenant will
       furnish Tenant's most recent audited financial statements (including any
       notes to them) to Landlord, or, if no such audited statements have been
       prepared, such other financial statements (and notes to them) as may have
       been prepared by an independent certified public accountant or, failing
       those, Tenant's internally prepared financial statements. Tenant will
       discuss its financial statements with Landlord and will give Landlord
       access to Tenant's books and records in order to enable Landlord to
       verify the financial statements. Landlord will not disclose any aspect of
       Tenant's financial statements that Tenant designates to Landlord as
       confidential except (a) to Landlord's lenders or prospective purchasers
       of the Project, (b) in litigation between Landlord and Tenant and (c) if
       required by court order or subpoena.

27.26  LANDLORD'S FEES. Whenever Tenant requests Landlord to take any action or
       give any consent required or permitted under this Lease, Tenant will
       reimburse Landlord for all of Landlord's reasonable costs incurred in
       reviewing the proposed action or consent, including without limitation
       engineers' or architects' fees, within 10 days after Landlord's delivery
       to Tenant of a statement of such costs. Tenant will be obligated to make
       such reimbursement without regard to whether Landlord consents to any
       such proposed action.

27.27  BINDING EFFECT. The covenants, conditions, and agreements contained in
       this Lease will bind and inure to the benefit of Landlord and Tenant and
       their respective heirs, distributees, executors, administrators,
       successors, and, except as otherwise provided in this Lease, their
       assigns.

27.28  TERMS. The necessary grammatical changes required to make the provisions
       hereof apply either to corporations, partnerships, or individuals, men or
       women, as the case may be, shall in all cases be assumed as though in
       each case fully expressed.

27.29  DEFINITION OF LANDLORD. All indemnities, covenants and agreements of
       Tenant contained herein which inure to the benefit of Landlord shall be
       construed to also inure to the benefit of Landlord's beneficiaries and
       their partners, agents and employees and employees of their agents.

27.30  RIGHTS CUMULATIVE. All rights and remedies of Landlord under this Lease
       shall be cumulative and none shall exclude any other rights and remedies
       allowed by law.

27.31  CHANGE OF BUILDING NAME. Landlord shall not name the Building after a
       competitor of RDD

27.32  FORCE MAJEURE. When a period of time is herein prescribed for any action
       to be taken by Landlord, Landlord shall not be liable or responsible for,
       and there shall be excluded from the computation for any such period of
       time, any delays due to strikes, riots, acts of God, shortages of labor
       or materials, war, regulations or restrictions or any other causes of any
       kind whatsoever which are beyond the control of Landlord.

27.33  THIRD PARTY BENEFICIARY. It is specifically understood and agreed that no
       person shall be a third party beneficiary hereunder, and that none of the
       provisions of this Lease shall be for the benefit of or be enforceable by
       anyone other than the parties hereto, and that only the parties hereto
       and their permitted assignees shall have rights hereunder.

27.34  NO JOINT VENTURE. Landlord and Tenant are not and shall not be deemed to
       be, for any purpose, partners or joint venturers with each other.

27.35  REMEDIES. If Tenant believes that Landlord has unreasonably withheld its
       consent in any instance in connection with this Lease, Tenant's sole
       remedy will be to seek a declaratory judgment that Landlord has
       unreasonably withheld its consent or any order of specific performance or
       mandatory injunction in

 (b) TENANT: Tenant will pay for:

     (1)  Tenant-initiated changes to the Final Space Plan or Working Drawings

          result in costs exceeding the Tenant finish allowance.

     (2)  Tenant-initiated Change Orders, modifications, or additions to the

<PAGE>   28
     (g)  Does not conform to applicable building code or is not approved by any
          governmental, quasi-governmental, or utility authority with
          jurisdiction over the Premises; or

6.   SCHEDULE OF IMPROVEMENT ACTIVITIES.

     (a)  On or before the Programming Information Submission Date, Tenant will
          cooperate with and submit to Landlord the Programming Information
          necessary for Landlord's architect to prepare the proposed space plan.

     (b)  Landlord's architect will expeditiously prepare a space plan and
          forward it to Tenant. Tenant will give Landlord written notice whether
          or not Tenant approves the proposed space plan within 5 days after its
          receipt. If Tenant's notice objects to the proposed space plan, the
          notice will set forth how the proposed space plan is inconsistent with
          the Programming Information and how the proposed space plan must be
          changed in order to overcome Tenant's objections. Landlord will
          resubmit a revised space plan to Tenant and it will be treated as
          though it was the first proposed space plan prepared pursuant to this
          paragraph.

     (c)  After Tenant approval of the Final Space Plan, Landlord will promptly
          cause to be prepared, a preliminary estimate of the cost of the
          Improvements as set forth in the final space plan (the "Estimated
          Construction Cost"). If the Estimated Construction Cost is less than
          the Tenant Finish Allowance, the Estimated Construction Cost will be
          deemed approved without a required response from the Tenant. If the
          Estimated Construction Cost is more than the Tenant Finish Allowance,
          Landlord will so notify Tenant in writing and Tenant will establish
          the Maximum Approved Cost by either:

          (1)  Agreeing in writing to pay the amount by which the Estimated
               Construction Cost exceeds the Tenant Finish Allowance; or

          (2)  Agreeing to have the Final Space Plan revised by Landlord's
               architect in order to assure that the Estimated Construction
               Cost is either:

               (A) No more than the Tenant Finish Allowance; or

               (B) Exceeds the Tenant Finish Allowance by an amount which
                   Tenant agrees to pay pursuant to clause (1) immediately
                   above.

          Tenant shall give immediate attention to establishing the Maximum
          Approved Cost by responding to Landlord within 2 business days. Upon
          Tenant's timely fulfillment of its obligations in either clause (1)
          or clause (2) immediately above, the Maximum Approved Cost will be
          established.

     (d)  Upon establishment of the Maximum Approved Cost, Landlord will cause
          to be prepared and delivered to Tenant the Working Drawings, the
          Construction Schedule, and the Tenant Cost Proposal for the
          improvements in accordance with the Final Space Plan. If the Tenant
          Cost Proposal is less than the Maximum Approved Cost, Landlord will
          take steps necessary to commence construction of the Improvements to
          the Premises.

          If the Tenant Cost Proposal is more than the Maximum Approved Cost,
          Landlord will so notify Tenant in writing and Tenant will either (1)
          agree in writing to pay the amount by which the Tenant Cost Proposal
          exceeds the Maximum Approved Cost or (2) request Landlord to revise
          the Working Drawings in order to assure that the Tenant Cost Proposal
          is no more than the Maximum Approved Cost.

          Tenant shall give immediate attention to the cost proposal approval
          process and to respond to Landlord within 3 business days.

     (e)  Following approval of the Working Drawings and the Tenant Cost
          Proposal, Landlord will cause application to be made to the
          appropriate governmental authorities for necessary approvals and
          building permits. Upon receipt of the necessary approvals and
          permits, Landlord will begin construction of the Improvements.


                                    Page C-3
<PAGE>   29
 8.  CHANGE ORDERS. Tenant may request changes to the Improvements during
     construction only by written instructions to Landlord's Representative on
     a form approved by Landlord. All such changes will be subject to
     Landlord's prior written approval in accordance with paragraph 5. Prior to
     commencing any change, Landlord will prepare and deliver to Tenant, for
     Tenant's approval, a Change Order setting forth the total cost of such
     change, which will include associated architectural, engineering,
     construction contractor's costs and fees, Construction Schedule changes,
     and the cost of Landlord's overhead. If Tenant fails to approve such
     change order within 5 business days after delivery by Landlord, Tenant
     will be deemed to have withdrawn the proposed change and Landlord will not
     proceed to perform the change. Upon Landlord's receipt of Tenant's
     approval, Landlord will proceed with the change.

 9.  EARLY ENTRY. Landlord shall permit Tenant and Tenant's employees and
     agents to enter the Premises prior to the Commencement Date so that Tenant
     may do such other work as may be required to make the Premises ready for
     Tenant's use and occupancy. Such entry prior to the Commencement Date
     will be upon the condition that Tenant and its employees, agents,
     contractors and suppliers shall work in harmony with Landlord and its
     employees, agents, contractors and suppliers and will not interfere with
     the performance of the work by Landlord or with the work of any other
     tenants or occupants in the Building. If at any time such entry shall
     cause or threaten to cause such disharmony or interference, Landlord shall
     have the right to withdraw such license upon 24 hours written notice to
     Tenant. Tenant agrees that any such entry or occupation of the Premises
     shall be governed by all of the terms, covenants, conditions and
     provisions of the Lease, except the covenant for the payment of Rent, and
     further agrees that Landlord shall not be liable in any way for injury,
     loss or damage which may occur to any of the Tenant's work or
     installations made in such Premises, Building or Project, or to any
     personal property placed therein, the same being at Tenant's sole risk.

10.  COMPLETION AND COMMENCEMENT DATE. Tenant's obligation for payment of Rent
     pursuant to the Lease will commence on the Commencement Date, which shall
     be November 15, 1995; however, the Commencement Date and the date for the
     payment of Rent may be delayed on a day-by-day basis for each day the
     substantial completion of the Improvements* is delayed by Landlord or its
     contractors or agents. The payment of Rent will not be delayed by a delay
     of substantial completion due to Tenant. The following are some examples
     of delays which will not affect the Commencement Date and the date Rent is
     to commence under the Lease:

     (a)  Late submissions of Programming Information;

     (b)  Change Orders requested by Tenant;

     (c)  Delays in obtaining non-Building Standard construction materials
          requested by Tenant;

     (d)  Tenant's failure to approve timely any item requiring Tenant's
          approval; and

     (e)  Delays by Tenant according to paragraph 6.

     In the event that substantial completion of the Improvements is delayed by
     Landlord, its contractors, or agents, the Commencement Date will be the
     date of substantial completion of the improvements, subject only to the
     completion of Landlord's punch-list items (that is, those items that do
     not materially interfere with Tenant's use and enjoyment of the Premises).
     Landlord and Tenant will confirm the Commencement Date in accordance with
     Section 3.1 of the Lease.

11.  CONDITION OF THE PREMISES.

     (a)  Prior to the Commencement Date, Landlord will arrange to have Tenant
          conduct a walk-through inspection of the Premises with Landlord and
          prepare a punch-list of items needing additional work by Landlord.
          Other than the items specified in the punch-list and "latent defects"
          (as defined below), by taking possession of the Premises Tenant will
          be deemed to have accepted the Premises in their condition on the date
          of delivery of possession and to have acknowledged that Landlord has
          installed the Improvements as required by this Workletter and that
          there are no items needing additional work or repair. The punch-list
          will not include any damage to the Premises caused by Tenant's move-in
          or early access, if permitted. Damage caused by Tenant will be
          repaired or corrected by Landlord at Tenant's expense. Tenant
          acknowledges that neither Landlord nor its agents or employees have
          made any representations or warranties as to the suitability or
          fitness of the Premises for the conduct of Tenant's business or for
          any other purpose, nor has Landlord or its agents or employees agreed
          to undertake any alterations or construct any Tenant improvements to
          the Premises except as expressly provided in this Lease and this
          Workletter. If Tenant fails to submit a punch-list to Landlord within
          5 days after the Commencement Date, it will be deemed that there are
          no items needing additional work or repair. Landlord's contractor will
          complete all reasonable punch-list items within 15 days after the
          walk-through inspection or as soon as practicable after such walk-
          through.

     (b)  A "latent defect" is a defect in the condition of the Premises caused
          by Landlord's failure to construct the

*   As conclusively established by the issuance of a Certificate of Substantial
    Completion by Landlord's Architect and delivery of possession to the
    Premises.




                                    Page C-4

          improvements in a good and workmanlike manner and in accordance with
          the working drawings, which defect would not ordinarily be observed
          during a walk-through inspection. If Tenant notifies Landlord of a
          latent defect within one year following the Commencement Date, then
          Landlord, at its expense, will repair such latent defect as soon as
          practicable. Except as set forth in this paragraph 11, Landlord will
          have no obligation or liability to Tenant for latent defects.

12.  NO LIABILITY. Preparation of the Final Space Plan and Working Drawings by
     or on behalf of Landlord shall create no responsibility or liability on the
     part of the Landlord for their completeness, design sufficiency, or
     compliance with all laws, ordinances, rules, regulations of governmental
     agencies or authorities, or the use and occupancy permit for the Building.

13.  ADJUSTMENTS UPON COMPLETION. As soon as practicable, upon completion of the
     Improvements in accordance with this Workletter, Landlord will notify
     Tenant of the Rentable Area of the Premises, the Rentable Area of the
     Building, Monthly Rent, and Tenant's Share, if such information was not
     previously determinable by Landlord, Tenant, within 10 days of Landlord's
     written request, will execute a certificate confirming such information.

RULES AND REGULATIONS


      1.    Landlord may from time to time adopt appropriate systems and
procedures for the security or safety of the Building, any persons occupying,
using, or entering the Building, or any equipment, finishings, or contents of
the Building, and Tenant will comply with Landlord's reasonable requirements
relative to such systems and procedures.

      2.    The sidewalks, halls, passages, exits, entrances, elevators, and
stairways of the Building will not be obstructed by any tenants or used by any
of them for any purpose other than for ingress to and egress from their
respective Premises. The halls, passages, exits, entrances, elevators,
escalators, and stairways are not for the general public, and Landlord will in
all cases retain the right to control and prevent access to such halls,
passages, exits, entrances, elevators, and stairways of all persons whose
presence in the judgment of Landlord would be prejudicial to the safety,
character, reputation, and interests of the Building and its tenants, provided
that nothing contained in these rules and regulations will be construed to
prevent such access to persons with whom any tenant normally deals in the
ordinary course of its business, unless such persons are engaged in illegal
activities. No tenant and no employee or agent of any tenant will go upon the
roof of the Building except to install, service and maintain such equipment,
systems and signs as Landlord shall allow Tenant to have on the roof, including
but not limited to Tenant's computer, air conditioning and satellite dishes.

      3.    No sign, placard, picture, name, advertisement, or written notice
visible from the exterior of Tenant's Premises will be inscribed, painted,
affixed, or otherwise displayed by Tenant on any part of the Building or the
Premises without the prior written consent of Landlord. Landlord will adopt and
furnish to Tenant general guidelines relating to signs inside the Building on
the office floors. Tenant agrees to conform to such guidelines. All approved
signs or lettering on doors will be printed, painted, affixed, or inscribed at
the expense of the Tenant by a person approved by Landlord. Other than
draperies expressly permitted by Landlord and building standard window
treatments, material visible from outside the Building will not be permitted.
In the event of the violation of this rule by Tenant, Landlord may remove the
violating items without any liability, and may charge the expense incurred by
such removal to the tenant or tenants violating this rule.

      4.    No cooking will be done or permitted by any tenant on the Premises,
except in areas of the Premises which are specially constructed for cooking and
except that use by the tenant of microwave ovens and Underwriters' Laboratory
approved equipment for brewing coffee, tea, hot chocolate, and similar
beverages will be permitted, provided that such use is in accordance with all
applicable federal, state, and city laws, codes, ordinances, rules, and
regulations.

      5.    No tenant will employ any person or persons other than the cleaning
service of Landlord for the purpose of cleaning the Premises, unless otherwise
agreed to by Landlord in writing. Except with the written consent of Landlord,
no person or persons other than those approved by Landlord will be permitted to
enter the Building for the purpose of cleaning it. No tenant will cause any
unnecessary labor by reason of such tenant's carelessness or indifference in
the preservation of good order and cleanliness. Should Tenant's actions result
in any increased expense for any required cleaning, Landlord reserves the right
to assess Tenant for such expenses.

      6.    The toilet rooms, toilets, urinals, wash bowls and other plumbing
fixtures will not be used for any purposes other than those for which they were
constructed, and no sweepings, rubbish, rags, or other foreign substances will
be thrown in such plumbing fixtures. All damages resulting from any misuse of
the fixtures will be borne by the tenant who, or whose servants, employees,
agents, visitors, or licensees, caused the same.

      7.    No tenant, or tenant's invitees or licensees, will in any way deface
any part of the Premises or the Building of which they form a part. In those
portions of the Premises where carpet has been provided directly or indirectly
by Landlord, Tenant will at its own expense install and maintain pads to
protect the carpet under all furniture having casters other than carpet casters.

      8.    No tenant will alter, change, replace, or rekey any lock or install
a new lock or a knocker on any door of the Premises. Landlord, its agents, or
employees will retain a pass (master) key to all door locks on the Premises.
Any new door locks required by Tenant or any change in keying of existing locks
will be installed or changed by Landlord following tenant's written request to
Landlord and will be at Tenant's expense. All new locks and rekeyed locks will
remain operable by Landlord's pass (master) key. Landlord will furnish each
tenant, free of charge, with two (2) keys to each suite entry door lock on the
Premises. Landlord will have the right to collect a reasonable charge for
additional keys and cards requested by any tenant. Each tenant, upon
termination of its tenancy, will deliver to Landlord all keys and access cards
for the Premises and Building that have been furnished to such tenant.

      9.    The elevator designated for freight by Landlord will be available
for use by all tenants in the Building during the hours and pursuant to such
procedures as Landlord may determine from time to time. The persons



                                    Page D-1
<PAGE>   32
employed to move Tenant's equipment, material, furniture, or other property in
or out of the Building must be acceptable to Landlord. The moving company must
be a locally recognized professional mover, whose primary business is the
performing of relocation services, and must be bonded and fully insured. A
certificate or other verification of such insurance must be received and
approved by Landlord prior to the start of any moving operations. Insurance
must be sufficient, in Landlord's sole opinion, to cover all personal
liability, theft or damage to the Project, including but not limited to floor
coverings, doors, walls, elevators, stairs, foliage, and landscaping. Special
care must be taken to prevent damage to foliage and landscaping during adverse
weather. All moving operations will be conducted at such times and in such a
manner as Landlord will direct, and all moving will take place during
non-Business Hours unless Landlord agrees in writing otherwise. Tenant will be
responsible for the provision of building security during all moving
operations, and will be liable for all losses and damages sustained by any
party as a result of the failure to supply adequate security. Landlord will
have the right to prescribe the weight, size, and position of all equipment,
materials, furniture, or other property brought into the Building. Heavy
objects will, if considered necessary by Landlord, stand on wood strips of such
thickness as is necessary to properly distribute the weight. Landlord will not
be responsible for loss of or damage to any such property from any cause, and
all damage done to the Building by moving or maintaining such property will be
repaired at the expense of Tenant. Landlord reserves the right to inspect all
such property to be brought into the Building and to exclude from the Building
all such property which violates any of these rules and regulations or the
Lease of which these rules and regulations are a part. Supplies, goods,
materials, packages, furniture, and all other items of every kind delivered to
or taken from the Premises will be delivered or removed through the entrance
and route designated by Landlord, and Landlord will not be responsible for the
loss or damage of any such property.

     10.  No tenant will use or keep in the Premises or the Building any
kerosene, gasoline, or inflammable or combustible or explosive fluid or
material or chemical substance other than limited quantities of such materials
or substances reasonably necessary for the operation or maintenance of office
equipment or limited quantities of cleaning fluids and solvents required in
tenant's normal operations in the Premises, which shall be stored in accordance
with applicable law. Without Landlord's prior written approval, no tenant will
use any method of heating or air conditioning other than that supplied by
Landlord.  No tenant will use or keep or permit to be used or kept any foul or
noxious gas or substance in the Premises.

     11.  Tenants shall not, prior to or during the Term, either directly or
indirectly, employ or permit the employment of any contractor, mover, mechanic
or laborer, or permit any materials in the Premises. If the use of such
contractor, mover, mechanic or laborer, or such materials would, in Landlord's
opinion, create any difficulty, strike or jurisdictional dispute with other
contractors, movers, mechanics or laborers engaged by Landlord, tenants, or
others, or would in any way disturb the construction, maintenance, cleaning,
repair, management, security or operation of the Building, Project or any part
thereof. Any tenant, upon demand by Landlord, shall cause all contractors,
movers, mechanics, laborers or materials causing such interference, difficulty
or conflict to leave or be removed from the Project immediately.

     12.  Landlord will have the right to prohibit any advertising by Tenant
mentioning the Building that, in Landlord's reasonable opinion, tends to impair
the reputation of the Building or its desirability as a building for offices,
and upon written notice from Landlord, tenant will refrain from or discontinue
such advertising.

     13.  Tenant will not bring any animals (except "Seeing Eye" dogs) or

or on the sidewalks outside the Building except in areas designated from time
to time by Landlord for such purposes.

     14.  All persons entering or leaving the Building between the hours of 6
p.m. and 7 a.m. Monday through Friday, and at all hours on Saturdays, Sundays,
and holidays will comply with such off-hour regulations as Landlord may
establish and modify from time to time. Landlord reserves the right to limit
reasonably or restrict access to the Building during such time periods.

     15.  Each tenant will store all its trash and garbage within its Premises.
No material will be placed in the trash boxes or receptacles if such material
is of such nature that it may not be disposed of in the ordinary and customary
manner of removing and disposing of trash and garbage without being in
violation of any law or ordinance governing such disposal. All garbage and
refuse disposal will be made only through entryways and elevators provided for
such purposes and at such times as Landlord designates. Removal of any
furniture or furnishings, large equipment, packing crates, packing materials,
and boxes will be the responsibility of each tenant and such items may not be
disposed of in the Building trash receptacles nor will they be removed by the
Building's janitorial service, except at Landlord's sole option and at the
tenant's expense. No furniture, appliances, equipment, or flammable products of
any type may be disposed of in the Building trash receptacles.

     16.  Canvassing, peddling, soliciting, and distributing handbills or any
other written materials in the Building are prohibited, and each tenant will
cooperate to prevent the same.

     17.  The requirements of the tenants will be attended to only upon
application by written, personal, or telephone notice at the office of the
Building. Employees of Landlord or Landlord's agent will not perform any work
or do anything outside of their regular duties unless under special

     18.  A directory of the Building will be provided for the display of the
name and location of tenants only. All entries on the Building directory
display will conform to standards and style set by Landlord in its sole
discretion.

     19.  Tenant will see that the doors of the Premises are closed and locked
and that all water faucets, water apparatus, and utilities are shut off before
Tenant or Tenant's employees leave the Premises, so as to prevent waste or
damage, and for any failure to comply or carelessness in this regard Tenant
will make good all injuries sustained by other tenants or occupants of the
Building or Landlord. On multiple-tenancy floors, all tenants will keep the
doors to the Building corridors closed at all times except for ingress and
egress.

     20.  Tenant will not conduct itself in any manner that is inconsistent
with the character of the Building as a first quality building or that will
impair the comfort and convenience of other tenants in the Building.

     21.  Tenant (including tenant's employees, agents, invitees, and visitors)
will use the parking spaces solely for the purpose of parking passenger model
cars, small vans, and small trucks and will comply in all respects with any
rules and regulations that may be promulgated by Landlord from time to time
with respect to the parking areas. The parking areas will not be used by
Tenant, its agents, or employees, for overnight parking of vehicles, except
with Landlord's prior consent. Tenant will ensure that any vehicle parked in
any of the parking spaces will be kept in proper repair and will not leak oil,
grease, gasoline, or any other fluids. If any of the parking spaces are at any
time used (a) for any purpose other than parking as provided above; (b) in any
way or manner reasonably objectionable to Landlord; or (c) by Tenant after
default by Tenant under the Lease. Landlord, in addition to any other rights
otherwise available to Landlord, may consider such default an event of default
under the Lease.

     22.  No act or thing done or omitted to be done by Landlord or Landlord's
agent during the term of the Lease in connection with the enforcement of these
rules and regulations will constitute an eviction by Landlord of any tenant nor
will it be deemed an acceptance of surrender of the Premises by any tenant, and
no agreement to accept such termination or surrender will be valid unless in a
writing signed by Landlord. The delivery of keys to any employee or agent of
Landlord will not operate as a termination of the Lease or a surrender of the
Premises unless such delivery of keys is done in connection with a written
instrument executed by Landlord approving the termination or surrender.

     23.  In these rules and regulations, the term "tenant" includes the
employees, agents, invitees, and licensees of Tenant and others permitted by
Tenant to use or occupy the Premises.

     24.  Landlord may waive any one or more of these rules and regulations
for the benefit of any particular tenant or tenants, but no such waiver by
Landlord will be construed as a waiver of such rules and regulations in favor
of any other tenant or tenants, nor prevent Landlord from enforcing any such
rules and regulations against any or all of the tenants of the Building after
such waiver.

     25.  These rules and regulations are in addition to, and will not be
construed to modify or amend, in whole or in part, the terms, covenants,
agreements, and conditions of the Lease.

EXHIBIT A

TOPIC MAPS DEVELOPMENT PHASE 1

SCOPE: Limited to exploration of application of Topic Maps, prototyping of a
tool and infrastructure issues relating to the knowledge domains in ADIS and
other Welters Kluwer companies.

ASSUMPTIONS:

        CONCEPT SCOPING: It is assumed that the key to this project overall, and
        to this first phase, is the initial concept discussions between MPower,
        Adis, Michel Biezunski of High Text, and Dianne Kennedy of SGML Resource
        Center. This is scheduled to be held in the second week of [*].

        This exercise will set out in detail the tasks for phase 1. At this
        stage it is assumed that the Adis thesaurus will be used as the
        knowledge domain.

        VERSION 1.0 PROTOTYPE: Software

        The deliverables for this prototype would consist of a WEB-based
        editorial tool for data entry, maintenance and display of
        Thesaurus/Topic Map terms. This may include the tools from High Text
        depending on the state of those tools. An object-server logical
        application design would also be delivered illustrating how the
        Thesaurus could be programmatically integrated into both text retrieval
        and other software application programs. The actual programming
        interfaces for the object-server would not be produced at this time.

        VERSION 1.0 PROTOTYPE: Content

        The approach toward content development is focused on the total amount
        of terms that are included in the prototype. It is estimated that
        approximately 7000 terms will need to be normalized into Topic Map term
        format. Key synonyms would also be included up to 1000 terms.

        The data structures for the prototype would be limited to the ADIS
        Thesaurus.

        A more complex initial model such as linking a logical sub-set (e.g.
        cardiology) of the ADIS Thesaurus to ICD-9 terms will also be explored.

        A broad drug hierarchy (therapeutic classes) design would also be
        included focused on generic and trade names up to 5000 terms. A sub-set
        of which could be inked to another terminology set (e.g. ACNs to NDCs
        for a sub-set population). Depending on what we decide, there may be
        some additional cost in licensing other terminologies if ADIS does not
        already have access to them.

        A rough cut on a conceptual database design which would include such
        possibilities as multiple industry and international standard
        vocabularies, and XML/SGML tagging.

        PEOPLE

        MPower will provide a Product Manager, highly experienced in Topic Map
        and vocabulary issues to lead the content elements together with a
        Programming Manager and other support programmers as appropriate
        together with overall Project Management and direction from Lorine
        Sweeney.

        Adis will provide key technical and editorial personnel for the initial
        scoping stage and meet the costs associated with the external
        consultants from High Text and SGML Resource Center.

        Adis would further provide 1 technical person and 1 editorial person for
        a period of up to 2 months from the beginning of the project to be based
        in Denver.

        TECHNOLOGY TOOLS AND ARCHITECTURE FOR PROOF OF CONCEPT

        The technology to be utilized for the prototype can be flexible however
        our preference would be the following.

        The database configuration for the final tool could be Oracle or SQL
        Server depending on the preference of ADIS. We would also consider
        developing the final business rules in C++ if that is ADIS's preference.
        The use of Visual Basic at the presentation layer will provide the
        ability to run either Windows or Net based clients.

PROJECT COSTS, PAYMENT AND ACCOUNTING

The project as initially scoped and costed on a hourly charge basis according to
the attached spread sheets is $US [*]. This is subject to review following
the initial concept meeting and may increase or decrease accordingly. However
the adjusted price will be based on a pro-rata basis depending on the hours
estimated following the concept meeting.

Adis will pay in stage payments each of one third, in advance, to be accounted
for against timesheets for the MPower staff.

CLINASSIST MARKET RESEARCH AND MARKET DEVELOPMENT PROJECT

SCOPE: To identify and recruit appropriate healthcare professionals, develop
structured discussion plan and conduct and report on, 2 focus groups to
validate the content, delivery and commercial assumptions of the ClinASSIST
Project as described in the attached New Product Development Proposal.

ASSUMPTIONS:

     TARGET HEALTHCARE PROFESSIONALS

     The target healthcare professionals for this project are as follows:

     Clinicians: Hospital ward based junior staff, Hospital based ward nursing
     staff, ambulatory care physicians.

     Commercial: Hospital administrators, COOs, CFOs, CIOs, GPOs and government
     purchasers.

     CLINASSIST CONTENT: It is assumed that a focus group of target clinicians
     will be shown the demonstration versions of ClinASSIST and then lead
     through a structured discussion to yield the following information:

     - Appropriateness and value of the core knowledge concept of providing drug
       and disease information which has been made specific to some
       pre-identified patient characteristics.

     - Appropriateness of the core assumption that this resource would provide
       80% of the information which non-super-specialist practising clinicians
       require.

     - The appropriateness of the broad disease subject headings i.e. does the
       product provide the right type of information on diseases?

     - The appropriateness of the broad drug subject headings i.e. does the
       product provide the right type of information on drugs?

     - The appropriateness and value of the pre-defined patient characteristics
       for both diseases and drugs.

     - Within each demonstrated disease or drug topic area the following:

          - The relevance of the data to non-super specialist practising
            clinicians.

          - The style of presentation i.e. is it succinct enough?, does it
            convey the information quickly enough?

          - The extent of the data, is it too short, too long?


<PAGE>   6
          o    Agreement with the actual data? Does it appear valid, are there
               disagreements with the data.

          o    The amount of 'drill-down' data provided. Is it enough should
               there be more and if so what and how much.


     CLINASSIST DELIVERY AND FORMAT CONCEPT: It is assumed that;

     1. A focus group of target clinicians will be shown the demonstration
     versions of ClinASSIST and then lead through a structured discussion to
     yield the following information;

     o    The overall reaction to the product in terms of physical presentation
          such as layout, type sizes, colours,

     o    The appropriateness of the navigation design from the initial screen
          offering disease or drug information, the understanding of where
          within the product the users is, clarity of understanding the context
          of the data provided, i.e. patient characteristics that are applying.

     o    Speed and ease of use

     2. A focus group of target hospital administrators/IS or IT personnel will
     be shown the demonstration versions of ClinASSIST and then lead through a
     structured discussion to yield the following information;

     o    The appropriateness of the overall Intranet concept, the use of IE 4
          or Netscape 4 as browser

     o    The practicality of delivery to all workstations within an institution

     ClinASSIST COMMERCIAL CONCEPT: It is assumed that a group of hospital
     administrators/CFO/COOs, government purchasers would be shown the product
     demonstration and sales plan and through structured discussion yield the
     following information;

     o    The overall perceived value to the institution of providing the
          product to all clinicians within the institution

     o    Degree of identification with the problems of inappropriate drug
          utilisation, drug missadventure, and quality (HEDIS) reminders/actions

     o    The perceived differences with existing drug and disease information
          resources

     o    The existence or otherwise of budgets for resources targeted to
          clinicians as opposed to pharmacy departments

     o    The positioning of the product as a $[*] per institution unlimited
          user resource

<PAGE>   7
MARKETING PLAN: It is assumed that the marketing plan development phase would
closely review the assumption in the attached New Product Development Proposal
and correct, adjust and supplement this document.

DELIVERABLES: The deliverables are in order;

     o Recruitment plan and participant lists
     o Structured discussion guide for each element
     o Meeting planning and logistics
     o Moderation of the discussion and recording
     o Focus group report
     o Marketing plan

Adis will review approve and provide comments on the deliverables

PEOPLE

MPower will provide Clinical and Marketing Specialists (Mark Rangell, Patrice
Light and Bill Doutre) to develop and direct and manage the project plus
marketing and administration support from Julianne Desmond and Jennifer
Engelhardt.

Adis will provide key editorial personnel to attend the focus groups as
observers and for discussion with the participants following the structured
discussion.

PROJECT COSTS, PAYMENT AND ACCOUNTING

The project has been scoped and costed on an hourly charge basis according to
the attached spread sheets.

Adis will pay in stage payments each of one third, at commencement of the
project, at the time of the focus meetings and on receipt of the report and
marketing plan.

Adis would provide payment in advance for the third party 'out of pocket'
expenses for the meetings, this payment to be accounted for by invoices.

Ladies and Gentlemen:

We were previously principal accountants for XCare.net (formerly MPOWER
Solutions Inc.) and, under the date of May 1, 1998, we reported on the financial
statements of MPOWER Solutions Inc. as of and for the years ended December 31,
1997 and 1996. We have not audited or reported on any of the financial
statements or information included in the registration statement referred to
below. On August 25, 1999, our appointment as principal accountants was
terminated. We have read XCare.net's statement included under the heading
"Change in Independent Accountants" of its Form S-1 dated November 2, 1999, and
we agree with such statements, except that we are not in a position to agree or
disagree with XCare.net's statement that the change was approved by its board of
directors and that we are not in a position to agree or disagree with
XCare.net's statement that PricewaterhouseCoopers LLP was not consulted
regarding items that involved accounting principles or the form of audit opinion
that might be rendered on XCare.net's financial statements.

Very truly yours,

(signed) KPMG LLP
