   This summary highlights information contained elsewhere in this prospectus.
This summary is not complete and does not contain all of the information you
should consider before investing in our common stock. You should read this
entire prospectus carefully.

   Unless otherwise indicated, all references in this prospectus to the number
of outstanding shares of our common stock:

  .  give effect to an amendment of our certificate of incorporation to
     increase the number of our authorized shares of common stock to 50
     million and to convert our existing Class A, Class B and Class C common
     stock into one class of common stock on the basis of a 1 for 3.05
     reverse stock split in the case of the Class A and Class C common stock,
     and a 1 for 2.67 reverse stock split in the case of the Class B common
     stock, immediately prior to this offering; and

  .  do not include the number of shares that we will issue if the
     underwriters exercise their over-allotment option.

In addition, the information in this prospectus assumes that the initial public
offering price will be $10.00 per share, the midpoint of the range disclosed on
the cover of this prospectus.

                                    Tanning

   We are an information technology services provider that architects, builds
and deploys enterprise solutions for companies throughout the world. We
specialize in large, complex, integrated solutions that incorporate online
transaction processing and very large databases. Internet technologies are a
central part of our solutions, enabling direct interaction among customers and
business partners on the World Wide Web, and among employees within
organizations on their private intranets. Our clients include Ameritech,
Blockbuster, BSkyB, E*Trade, Federal Express, Maersk Line, MCI WorldCom, R.R.
Donnelley Financial and U S WEST.

   We focus on the most challenging and critical assignments in the information
technology industry. Our solutions typically involve:

  .  ultra-high transaction rates (up to millions per hour);

  .  very large databases (terabytes of information); and

  .  business-critical operational requirements for reliability, scalability,
     flexibility and availability.

   Our key solutions are:

  .  Electronic commerce solutions, which enable businesses to interact with
     customers, suppliers and other business partners directly and sell
     products and services through the Internet. For example, we designed
     international extensions to E*Trade's domestic trading system to enable
     it to expand its trading services into foreign countries.

  .  Enterprise customer relationship management solutions, which enhance a
     business' ability to identify, attract, retain and support customers
     using emerging and established channels such as the World Wide Web,
     direct sales, telemarketing and call centers, direct mail and retail
     facilities. For example, we redesigned Blockbuster's existing enterprise
     architecture to effectively manage customer data and account activity
     information for over 40 million customers and more than 6,000 stores.

  .  Core operations solutions, which improve business processes such as
     billing system integration and order, claim, trade, credit card
     transaction and operation transaction processing. For example, we
     created an online transaction processing system for Federal Express
     capable of handling 1,000

                                       3
<PAGE>


     transactions per second on a one-plus terabyte database, enabling
     Federal Express to obtain information about the performance of its
     package delivery system in significantly shorter time frames (hours vs.
     days).

   With advances in the Internet and technology, new business models and
innovative information technology solutions are emerging that can transform the
way companies run their businesses. As part of this evolution of business
models, companies are seeking value from electronic commerce, customer
relationship management and core operations solutions. We believe that we are
differentiated by our focus on, and expertise in, the architecture, complex
integration, high volume online transaction processing capabilities and very
large databases required to successfully deploy these advanced solutions. For
many clients, the systems we build are at the core of their efforts to
capitalize on information technology and the Internet.

   Our company traces its history back to 1993 and is currently incorporated in
Delaware. Our principal executive office is located at 4600 South Ulster
Street, Suite 380, Denver, Colorado 80237, and our telephone number is (303)
220-9944. We maintain a site on the World Wide Web at http://www.tanning.com;

                                  RISK FACTORS

   This offering involves a high degree of risk. You should carefully consider
the risks described below and the other information in this prospectus,
including our consolidated financial statements and the related notes, before
you purchase any shares of our common stock.

Risks Related to Our Business

Inability to manage our growth could have a material adverse effect on the
quality of our services, our ability to retain key personnel, and our business

   Our growth has placed significant demands on our management and other
resources. Our revenues increased approximately 28% from 1997 to 1998. Our
staff increased from 120 full-time employees at December 31, 1997 to 148 at
December 31, 1998, and to 177 at March 31, 1999. Our future success will depend
on our ability to manage our growth effectively, including:

  .  continuing to train, motivate, manage and retain our existing employees
     and attract and integrate new employees;

  .  improving our business development capabilities;

  .  maintaining high rates of employee utilization;

  .  accurately estimating time and resources for engagements;

  .  developing and improving our operational, financial, accounting and
     other internal systems and controls; and

  .  maintaining project quality.

   Our management has limited experience managing a business of Tanning's size.
If we are unable to manage our growth and projects effectively, it could have a
material adverse effect on the quality of our services, our ability to retain
key personnel, and our business and results of operations.

   In anticipation of business growth, we expect to incur costs and expend
capital. We can give no assurances that we will continue to grow, or that we
will grow at a pace that will support these costs and expenditures. To the
extent revenues do not increase at a rate commensurate with these additional
costs and expenditures, our results of operations and liquidity could be
materially and adversely affected. In addition, we expect that our plans for
increases in expenses and capital expenditures over the next two and one-half
years to support our growth could negatively impact profitability.

We must attract and retain professional staff in order to complete our projects
and obtain new projects

   Our business is labor intensive, and our success depends on identifying,
hiring, training and retaining experienced, knowledgeable professionals. If a
significant number of our current employees or any of our project managers or
senior technical personnel leave, we may be unable to complete or retain
existing projects or bid for new projects of similar scope and revenue. In
addition, former employees may compete with us in the future.

   Even if we retain our current employees, our management must continually
recruit talented professionals in order for our business to grow. There is
currently a shortage of qualified project managers and senior technical
personnel in the information technology services field, and this shortage is
likely to continue. Furthermore, there is significant competition for employees
with the skills required to perform the services we offer. We cannot give any
assurances that we will be able to attract a sufficient number of qualified
employees in the future, or that we will be successful in motivating and
retaining the employees we are able to attract. If we cannot attract, motivate
and retain qualified professionals, our business, financial condition and
results of operations will suffer.

                                       6

We depend heavily on our principal clients; a significant reduction in the work
performed for any of them could harm our revenues and operating results

   We derive a large portion of our services revenue from a limited number of
clients. Services revenue constitutes substantially all of our revenues. In
1997, our five largest clients accounted for approximately 81%

                                      6--1
<PAGE>


of our services revenue, with Ameritech accounting for approximately 41% of our
services revenue and Oxford Health Plans accounting for approximately 23% of
our services revenue. In 1998, our five largest clients accounted for
approximately 70% of our services revenue, with Maersk Line accounting for
approximately 31% of our services revenue, U S WEST accounting for
approximately 12% of our services revenue and E*Trade and CSX Technology each
accounting for approximately 10% of our services revenue. In the first three
months of 1999, our five largest clients accounted for approximately 74% of our
services revenue, with Maersk Line accounting for approximately 31% of our
services revenue and U S WEST, E*Trade, and Ameritech each accounting for
approximately 12% of our services revenue. The volume of work performed for our
principal clients may not be sustained from year to year, and there is a risk
that these principal clients may not retain us in the future. Any cancellation,
deferral or significant reduction in work performed for these principal clients
or a significant number of smaller clients could have a material adverse effect
on our financial condition and results of operations. See "Business--Clients"
for more information relating to our clients.

Our clients may terminate projects before completion; this could adversely
affect our revenues and earnings

   In general, our clients may terminate project engagements upon limited
notice and without significant penalty. This makes our results of operations
difficult to predict. Our clients' termination of our project engagements would
result in lower revenues and underutilized employees and, as a result, would
negatively affect our earnings. For example, a client's termination of a
significant project in the fourth quarter of 1997 adversely affected revenues,
employee utilization and earnings in the first half of 1998. For a further
discussion of the impact of this project termination, see "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

We may have difficulty in managing our international operations and expansion,
which could adversely affect our business

   We currently have significant operations in Europe and intend to expand our
business to other regions, as attractive opportunities arise. Revenues from our
existing international operations represented 35% of services revenue in 1998
and in the first three months of 1999 and 86% of our income before income taxes
in 1998 and 55% of our income before income taxes in the first three months of
1999. We may incur significant costs in connection with our international
expansion.

   There are also risks inherent in doing business in foreign countries,
including:

  .  changes in legal and regulatory requirements;

  .  enactment of export and import restrictions, tariffs and other trade
     barriers;

  .  currency fluctuations and the on-going conversion to the euro in several
     member states of the European Union;

  .  difficulties in staffing and managing foreign offices as a result of,
     among other things, distance and language and cultural differences;

  .  political and economic instability;

  .  seasonal reductions in business activity;

  .  longer payment cycles and problems in collecting accounts receivable;
     and

  .  potentially adverse tax consequences.

Any of these factors could have a material adverse effect on our business,
financial condition and results of operations.

                                       7

We may fail to accurately estimate the time and resources necessary for the
performance of our services, which could reduce the profitability of, or
result in a loss on, our projects and damage our customer relationships

   To date, we have generally provided services to our clients on a time and
materials basis, although we sometimes work on a fixed-fee or capped fee
basis. In the future, we anticipate that an increasing percentage of our
client engagements will be subject to fixed-fee or other arrangements that are
not solely based on time and materials. Because we work with complex
technologies in compressed timeframes and because we have limited experience
in pricing engagements on these terms, it can be difficult to judge the time
and resources necessary to complete a project. Our failure to accurately
estimate the time and resources required for a project, or our failure to
complete our obligations in a manner consistent with the project plan upon
which our fixed-fee or other arrangements are based, could reduce the
profitability of, or result in a loss on, our projects if we are required to
devote additional resources to project engagements for which we will not
receive additional compensation, and could damage our customer relationships
and our reputation.

Quarter to quarter fluctuations in our revenues and earnings could affect the
market price of our common stock

   Our revenues and earnings may vary from quarter to quarter as a result of a
number of factors, including:

  .  number, size and scope of client engagements commenced or completed
     during a quarter;

  .  employee utilization rates;

  .  unanticipated project terminations, delays or deferrals;

  .  the accuracy of estimates of resources required to complete ongoing
     projects; and

  .  the contractual terms and degree of completion of projects in which we
     are engaged.

   Because a high percentage of our expenses, particularly compensation and
rent, are fixed in advance of any particular quarter, any of the factors
listed above could cause significant variations in our earnings in any given
quarter. Any decline in revenues or earnings or a greater than expected loss
for any quarter could materially adversely affect the market price of our
common stock, even if not reflective of any long-term problems with our
business.

We compete in a rapidly evolving and highly competitive industry that has low
barriers to entry

   The business areas in which we compete are intensely competitive and
subject to rapid technological change. We expect competition to continue and
intensify. Our competitors fall into four major categories:

  .  large information technology consulting services providers, such as
     Andersen Consulting, KPMG, PricewaterhouseCoopers, IBM, EDS and CSC;

  .  mid-tier information technology services providers, such as Cambridge
     Technology Partners and Sapient;

  .  Internet professional service providers, such as Modem Media . Poppe
     Tyson, US Interactive, Proxicom, Viant and Scient; and

  .  internal information technology departments of current and potential
     clients.

   Many of our competitors have longer operating histories and client
relationships, greater financial, technical, marketing and public relations
resources, larger client bases and greater brand or name recognition than we
have. Our competitors may be able to respond more quickly to technological
developments and changes in clients' needs.


                                       8
<PAGE>

   Further, there are low barriers to entry into our business. We do not own
any technologies that preclude or inhibit competitors from entering our
industry. Existing or future competitors may independently develop and patent
or copyright technologies that are superior or substantially similar to our
technologies. The costs to develop and provide information technology
consulting services are relatively low. Therefore, we expect to continue to
face additional competition from new entrants into our industry. See
"Business--Competition" for a further discussion of competition within our
industry.

Year 2000 issues could seriously harm our business as a result of reduced
demand for our services, internal and external operations difficulties, and
potential disputes with, or liabilities to, clients

   The Year 2000 problem is the potential for system and processing failures of
date-related data arising from the use of two digits by computer-controlled
systems, rather than four digits, to define the applicable year. Clients' and
potential clients' purchasing patterns may be affected by Year 2000 issues as
companies expend significant resources to correct or replace their current
systems for Year 2000 compliance. These clients and potential clients may have
fewer funds available to purchase our services, which could adversely affect
our business, financial condition and results of operations. We may experience
operations difficulties because of undetected errors or defects in the
technology we use in our internal systems. We also rely, directly and
indirectly, on the systems of business enterprises such as clients, suppliers,
utilities, creditors and financial institutions, both domestic and
international, which could be subject to operational difficulties arising out
of Year 2000 issues. In addition, we have made representations to clients
regarding Year 2000 compliance and may become involved in disputes regarding
Year 2000 problems involving solutions that we have developed or implemented.
Any failure on the part of our principal internal systems, other business'
systems or the systems that we create for our clients as a result of the Year
2000 problem could seriously harm our business, reputation, financial condition
and results of operations. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Year 2000."

Expansion of our solutions and service offerings may not be successful and we
may lose opportunities to expand our business

   In addition to growing our business within the disciplines on which we
currently focus, an element of our strategy is to expand our solutions in the
area of supply chain management and our service offerings in areas such as
business consulting, process innovation and creative design. Successful
expansion in these areas will require:

  .  attracting, integrating and retaining talented personnel;

  .  successfully marketing and delivering these services; and

  .  successfully establishing relationships with vendors and technology
     providers.

   Failure to develop additional solutions and service offerings on a timely
basis could cause us to lose opportunities for business with both existing and
potential clients. We cannot assure you that this expansion will be successful.

We may have difficulty responding to changing technology, industry standards
and client preferences, which could cause us to lose business

   Our success will depend in part on our ability to develop information
technology solutions that keep pace with continuing changes in technology,
evolving industry standards and changing client preferences. We cannot give any
assurances that we will be successful in addressing these developments on a
timely basis or at all. Our failure to respond quickly and cost-effectively to
new developments could cause us to lose current and potential business
opportunities and have a material adverse effect on our business and results of
operations.

   In particular, we have derived a significant portion of our revenues from
projects based primarily on:

  .  open system technologies, which are standards-based, non-proprietary
     technologies;

                                       9
<PAGE>


  .  multi-tier software architecture, in which the key layers of an
     application system are separated and optimized independently to improve
     performance, scalability and reliability;

  .  web-based architectures; and

  .  electronic commerce, generally.

   These areas are continuing to develop and are subject to rapid change. Any
factors negatively affecting the acceptance of information processing systems
using client/server and web-based architectures could have a material adverse
effect on our business, especially if we are unable to develop skills and
replacement technologies for these types of information processing systems.

Our business may suffer if growth in the use of the Internet declines

   Because Internet technologies are a central part of our solutions, our
business depends upon continued growth in the use of the Internet by our
clients, prospective clients and their customers and suppliers. Capacity
constraints caused by growth in Internet usage may, unless resolved, impede
further growth in Internet use. If the number of users on the Internet does not
increase and commerce over the Internet does not become more accepted and
widespread, demand for our services may decrease and our business and results
of operations could suffer. Factors which may affect Internet usage or
electronic commerce adoption include:

  .  actual or perceived lack of security of information;

  .  lack of access and ease of use;

  .  congestion of Internet traffic or other usage delays;

  .  inconsistent quality of service;

  .  increases in access costs to the Internet;

  .  excessive government regulation;

  .  uncertainty regarding intellectual property ownership;

  .  reluctance to adopt new business methods;

  .  costs associated with the obsolescence of existing infrastructure; and

  .  economic viability of the Internet commerce model.

Misappropriation of our intellectual property could harm our reputation, affect
our competitive position and cost us money

   We believe our intellectual property, including our proprietary
methodologies, is important to our success and competitive position. If we are
unable to protect our intellectual property against unauthorized use by others,
our reputation among existing and potential clients could be damaged and our
competitive position adversely affected.

   Our strategies to deter misappropriation could be inadequate in light of the
following risks:

  .  non-recognition of the proprietary nature of or inadequate protection of
     our methodologies in the United States or foreign countries;

  .  undetected misappropriation of our proprietary methodologies;

  .  development of similar software or applications by our competitors; and

  .  unenforceability of the non-competition and confidentiality agreements
     entered into by our key employees.

                                       10
<PAGE>

   If any of these risks materialize, we could be required to spend significant
amounts to defend our rights and our managerial resources could be diverted. In
addition, our proprietary methodologies may decline in value or our rights to
them may not be enforceable. See "Business--Intellectual property rights" for
more information concerning our intellectual property.

Others could claim that we infringe on their intellectual property rights,
which may result in substantial costs, diversion of resources and management
attention and harm to our reputation

   Although we believe that our services do not infringe on the intellectual
property rights of others, we cannot give any assurances that an infringement
claim will be successfully defended. A successful infringement claim against us
could materially and adversely affect us in the following ways:

  .  we may be liable for damages and litigation costs, including attorneys'
     fees;

  .  we may be enjoined from further use of the intellectual property;

  .  we may have to license the intellectual property, incurring licensing
     fees;

  .  we may have to develop a non-infringing alternative, which could be
     costly and delay projects; and

  .  we may have to indemnify clients with respect to losses incurred as a
     result of our infringement of the intellectual property.

   Regardless of the outcome, an infringement claim could result in substantial
costs, diversion of resources and management attention, clients' termination of
project engagements and harm to our reputation.

Our business and our client relationships may suffer if we have disputes over
our right to resell or reuse intellectual property developed for specific
clients

   A portion of our business involves the development of software applications
for specific client engagements. Ownership of client-specific software is
generally retained by the client, although we retain rights to some of the
applications, processes and other intellectual property developed in connection
with client engagements. Issues relating to the rights to intellectual property
can be complicated. We cannot give any assurances that disputes will not arise
that affect our ability to resell or reuse such applications, processes and
other intellectual property, damage our relationships with our clients, divert
our management's attention or have a material adverse effect on our business,
financial condition and results of operations.

Potential acquisitions may result in, among other things, increased expenses,
difficulties in integrating target companies and diversion of management's
attention

   An element of our strategy includes expanding our solutions and service
offerings and gaining access to new technologies through strategic acquisitions
and investments when attractive opportunities arise. Some of the risks that we
may encounter in implementing this element of our strategy include:

  .  expenses and difficulties in identifying potential targets and the costs
     associated with acquisitions that are abandoned before completion;

  .  expenses, delays and difficulties of integrating the acquired company
     into our existing organization and our company's culture;

  .  diversion of management's attention during the acquisition process;

  .  diversion of management's attention following the acquisition process
     where management has options or other equity incentive rights in the
     acquired company;

  .  expenses of amortizing the acquired company's intangible assets, which
     could be significant in light of the high valuations of many companies
     in the information technology industry;

  .  impact on our financial condition due to the timing of the acquisition;
     and

                                       11
<PAGE>


  .  expenses of any undisclosed or potential legal liabilities of the
     acquired company, including intellectual property, employment, and
     warranty and product liability-related problems.

If realized, any of these risks could have a material adverse effect on our
business, financial condition and results of operations.

We must maintain our reputation and expand our name recognition to remain
competitive

   We believe that establishing and maintaining a good reputation and name
recognition are critical for attracting and expanding our client base. We also
believe that the importance of reputation and name recognition will increase
due to the growing number of information technology service providers. If our
reputation is damaged or if potential clients are not familiar with us or the
services we provide, we may become less competitive or lose our market
position. Promotion and enhancement of our name will depend largely on our
success in continuing to provide large, complex, integrated information
technology solutions. If clients do not perceive our solutions to be effective
or of high quality, our brand name and reputation will suffer.

Lack of detailed written contracts could impair our ability to collect fees,
protect our intellectual property and protect ourselves from liability to
others

   We try to protect ourselves by entering into detailed written contracts with
our clients covering the terms and contingencies of the project engagement. In
some cases, however, consistent with what we believe to be industry practice,
work is performed for clients on the basis of a limited statement of work or
verbal agreements before a detailed, written contract can be finalized. To the
extent that we fail to have detailed written contracts in place, our ability to
collect fees, protect our intellectual property and protect ourselves from
liability to others may be impaired.

Concentration of ownership of our common stock may limit your ability to
influence corporate matters

   Immediately following this offering, our executive officers and directors
together with Stephen Brobst and entities controlled by AEA Tanning Investors
Inc. will beneficially own approximately 82% of the outstanding shares of our
common stock.

   A number of our large stockholders are parties to an agreement under which
they have agreed to vote in favor of their nominees to our board of directors.
Because they will own approximately 66% of the outstanding shares of our common
stock immediately following this offering, they will have the voting power to
cause their nominees to be elected. If our significant stockholders choose to
act or vote together on other matters, they will have the power to control the
approval of any other action requiring the approval of our stockholders,
including any amendments to our certificate of incorporation and mergers,
acquisitions or sales of all of our assets. In addition, without the consent of
these stockholders, we could be prevented from entering into transactions that
could be beneficial to us. Also, third parties could be discouraged from making
a tender offer or bid to acquire our company at a price per share that is above
the then-prevailing market price. See "Certain Transactions--Stock Purchase
Agreement, Shareholder Agreement and Registration Rights Agreement" and
"Principal Stockholders" for more information regarding the stock ownership of
our officers, directors and significant stockholders.

Government regulation and legal uncertainties relating to the Internet could
adversely affect our business

   Increased regulation of the Internet might slow the growth in use of the
Internet, which could decrease demand for our services, increase our cost of
doing business or otherwise harm our business. Congress, federal regulatory
agencies and the states have recently passed legislation or taken other actions
regulating certain aspects of the Internet, including on-line content,
interaction with children, copyright infringement, user

                                       12
<PAGE>


privacy, taxation, access charges, liability for third-party activities,
transmission of sexually explicit material, defamation, consumer protection and
jurisdiction. Foreign governments have also taken actions to regulate aspects
of the Internet, including user privacy and on-line content. In addition,
federal, state and local governmental organizations as well as foreign
governments are considering other legislative and regulatory proposals that
would regulate these and other aspects of the Internet. We do not know how
courts will interpret laws governing the Internet or the extent to which they
will apply existing laws to the Internet. Therefore, we are not certain how
existing or future laws governing the Internet or applied to the Internet will
affect our business.

Risks Related to this Offering

External factors could adversely affect the market price of our common stock

   There is currently no public market for our common stock, and we cannot
assure you that an active trading market will develop or be sustained after
this offering. The initial public offering price will be determined through
negotiation between us and representatives of the underwriters and may not be
indicative of the market price for our common stock after this offering.

   The market price of our common stock could fluctuate significantly as a
result of:

  .   our susceptibility to quarter to quarter variations in our operating
     results, which may cause us to fail to meet analysts' or investors'
     expectations;

  .  economic and stock market conditions specific to information technology
     services providers;

  .  changes in financial estimates by securities analysts following our
     stock;

  .  earnings and other announcements by, and changes in market evaluations
     of, providers of information technology services;

  .  changes in business or regulatory conditions affecting information
     technology services;

  .  announcements or implementation by us or our competitors of
     technological innovations or new products or services; and

  .  trading volume of our common stock.

   The securities of many companies have experienced extreme price and volume
fluctuations in recent years, often unrelated to the companies' operating
performance. Specifically, market prices for securities of Internet-related and
technology companies have frequently reached elevated levels, often following
their initial public offerings. These levels may not be sustainable and may not
bear any relationship to these companies' operating performances. If the market
price of our common stock reaches an elevated level following this offering, it
may materially and rapidly decline. In the past, following periods of
volatility in the market price of a company's securities, stockholders have
often instituted securities class action litigation against the company. If we
were involved in a class action suit, it could divert the attention of senior
management, and, if adversely determined, have material adverse effect on our
business and financial condition.

The sale or availability for sale of substantial amounts of our common stock
could adversely affect its market price

   Sales of substantial amounts of our common stock in the public market after
the completion of this offering, or the perception that these sales could
occur, could adversely affect the market price of our common stock and could
materially impair our future ability to raise capital through offerings of our
common stock. There will be 19,606,002 shares of common stock outstanding
immediately after this offering, or 20,206,002 shares if the underwriters
exercise their over-allotment option in full. The 4,000,000 shares sold in this
offering

                                       13
<PAGE>


will be freely tradeable without restriction or further registration under the
Securities Act, unless held by our "affiliates" as that term is defined in Rule
144 under the Securities Act. The 15,606,002 shares of common stock outstanding
prior to this offering are "restricted securities" as defined in Rule 144 and
may not be sold in absence of registration other than in accordance with Rule
144 or Rule 701 under the Securities Act or another exemption from
registration.

   In connection with this offering, we, our officers and directors and some of
our stockholders have agreed, except in limited circumstances, not to sell any
shares of common stock for 180 days after completion of this offering without
the underwriters' consent; however, the underwriters may release these shares
from these restrictions at any time. We cannot predict what effect, if any,
market sales of shares held by principal stockholders or any other stockholder
or the availability of these shares for future sale will have on the market
price of our common stock. See "Shares Eligible for Future Sale" for a more
detailed description of the restrictions on selling shares of our common stock
after this offering.

The net proceeds of this offering may be allocated in ways with which you and
other stockholders may not agree

   Our management has significant flexibility in applying the proceeds we
receive in this offering. Because the proceeds are not required to be allocated
to any specific investment or transaction, you cannot determine at this time
the value or propriety of our management's application of the proceeds on our
behalf and you and other stockholders may not agree with our decisions. See
"Use of Proceeds" for a more detailed description of how management intends to
apply the proceeds of this offering.

Investors in this offering will experience immediate and substantial dilution

   If you purchase common stock in this offering, you will pay more for your
shares than the amounts paid by existing stockholders for their shares. As a
result, you will experience immediate and substantial dilution of approximately
$7.20 per share, representing the difference between our net tangible book
value per share as of March 31, 1999, after giving effect to this offering and
the assumed public offering price of $10.00 per share. In addition, you may
experience further dilution to the extent that shares of our common stock are
issued upon the exercise of stock options. These shares will be issued at a
purchase price less than the public offering price per share in this offering.
See "Dilution" for a more complete description of how the value of your
investment in our common stock will be diluted upon the completion of this
offering.

Anti-takeover provisions of Delaware's General Corporation Law and our
certificate of incorporation could delay or deter a change in control

   Amendments we intend to make to our certificate of incorporation and our
bylaws, as well as various provisions of the Delaware General Corporation Law,
may make it more difficult to effect a change in control of our company. The
existence of these provisions may adversely affect the price of our common
stock, discourage third parties from making a bid for our company or reduce any
premiums paid to our stockholders for their common stock. For example, we
intend to amend our certificate of incorporation to authorize our board of
directors to issue up to 5.0 million shares of "blank check" preferred stock
and to attach special rights and preferences to this preferred stock. The
issuance of this preferred stock may make it more difficult for a third party
to acquire control of us. We also intend to amend our certificate of
incorporation to provide for the division of the board of directors into three
classes as nearly equal in size as possible with staggered three-year terms.
This classification of the board of directors could have the effect of making
it more difficult for a third party to acquire our company, or of discouraging
a third party from acquiring control of our company. See "Description of
Capital Stock--Preferred stock," and "Description of Capital Stock--Anti-
takeover effects of our certificate of incorporation and bylaws and provisions
of Delaware law" for a more complete description of our capital stock, our
certificate of incorporation and the effects of the Delaware General

             CAUTIONARY NOTICE REGARDING FORWARD-LOOKING STATEMENTS

   This prospectus includes "forward-looking statements" for purposes of the
Securities Act of 1933 and the Securities Exchange Act of 1934. All statements
other than statements of historical fact in this prospectus, including
statements regarding our competitive strengths, business strategy, future
financial position, budgets, projected costs and plans and objectives of
management are forward-looking statements. In addition, forward-looking
statements generally can be identified by the use of forward-looking
terminology such as "may," "will," "expect," "should," "intend," "estimate,"
"anticipate," "believe," "continue" or similar terminology. We can give no
assurance that the expectations reflected in forward-looking statements will
prove to have been correct. Our actual results could differ materially from
those anticipated in these forward-looking statements as a result of factors
including those set forth under the "Risk Factors," "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and "Business"
sections, and elsewhere in this prospectus. All written and oral forward-
looking statements attributable to us are expressly qualified in their entirety
by the factors we disclose that could cause our actual results to differ
materially from our expectations. We undertake no obligation to update publicly
or revise any forward-looking statements.

                                USE OF PROCEEDS

   We estimate that we will receive net proceeds of approximately $36.0
million, or approximately $41.5 million if the underwriters' over-allotment
option is exercised in full, from the sale of the shares of common stock
offered by us, at an assumed initial public offering price of $10.00 per share,
after deducting the estimated underwriting discounts and commissions and
offering expenses payable by us.

   We expect to use the net proceeds of the offering for general corporate
purposes, including:

  .  working capital;

  .  additional personnel;

  .  increased facilities; and

  .  computers and network equipment.

   An element of our strategy includes expanding our solutions and service
offerings and gaining access to new technologies through strategic acquisitions
and investments when attractive opportunities arise. At the present time, we
have no understanding, commitment or agreement with respect to any acquisition
or investment. Pending these uses, we intend to invest the net proceeds from
this offering in U.S. government securities and other investment-grade,
interest-bearing instruments.

   The foregoing represents our present intentions with respect to the
allocation of the net proceeds of this offering based upon our present plans
and business conditions. The occurrence of unforeseen events or changed
business conditions could result in the application of the proceeds of this
offering in a manner other than as described in this prospectus. See "Risk
Factors--Our management has broad discretion over the use of proceeds from this
offering" for a discussion of this risk.

                                DIVIDEND POLICY

   Our board of directors has never declared or paid any cash dividends on our
common stock and does not expect to do so in the foreseeable future. We
currently intend to retain any earnings to finance the expansion and
development of our business. Our board of directors will make any future
determination of the payment of dividends based on conditions then existing,
including our earnings, financial condition and capital requirements, as well
as such economic and other conditions as the board of directors may deem
relevant. In addition, the payment of dividends may be limited by financing
agreements that we may enter into in the future.

                                    DILUTION

   Our net tangible book value as of March 31, 1999 was approximately $18.6
million, or $1.20 per share. Net tangible book value per share is equal to our
total tangible assets minus our total liabilities divided by the number of
shares of our common stock outstanding. Assuming we had sold the 4,000,000
shares of common stock offered hereby at an initial public offering price of
$10.00, and after deducting underwriting discounts and commissions and
estimated offering expenses payable by us, our net tangible book value at March
31, 1999 would have been approximately $54.6 million, or $2.80 per share. This
represents an immediate increase in net tangible book value of $1.60 per share
to existing stockholders and an immediate dilution of $7.20 per share to new
investors. Dilution is determined by subtracting net tangible book value per
share after this offering from the amount of cash paid by a new investor for a
share of common stock. The following table illustrates the substantial and
immediate per share dilution to new investors:

   The following table summarizes as of March 31, 1999 the number of shares of

</TABLE>

   If the underwriters exercise their over-allotment option in full, the pro
forma net tangible book value per share of common stock as of March 31, 1999
would have been $2.99 per share, which would result in dilution to the new
investors of $7.01 per share, and the number of shares held by the new
investors will increase to 4,600,000, or 23% of the total number of shares to
be outstanding after this offering.

   The foregoing tables assume no exercise of any outstanding stock options to
purchase common stock. As of March 31, 1999, there were outstanding options to
purchase an aggregate of 5,402,410 shares of common stock at a weighted average
exercise price of $3.60 per share under our stock option plans. If all of these
options had been exercised on March 31, 1999 before the issuance of common
stock from this offering, our net tangible book value would have been
approximately $38.0 million or $1.82 per share. On issuance of common stock
from this offering, our pro forma net tangible book value on March 31, 1999
would have been approximately $74.0 million, or $2.97 per share, the increase
in net tangible book value attributable to new investors would have been $1.15
per share and the dilution in net tangible book value to new investors would
have been $7.03 per share.

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

   The following discussion and analysis should be read in conjunction with our
consolidated financial statements and the notes to our consolidated financial
statements, each of which is included in this prospectus. This prospectus
contains forward-looking statements relating to future events and our future
financial performance. Actual results could be significantly different from
those discussed in this prospectus. Factors that could cause or contribute to
such differences include those summarized in the section entitled "Risk
Factors," as well as those discussed in other sections of this prospectus.

Overview

   Our revenue is comprised primarily of fees generated for professional
services. To date, we have generally provided services to our clients on a time
and materials basis, although we sometimes work on a fixed-fee basis. Under
time and materials contracts, we recognize revenue as services are provided.
Under fixed-fee contracts, we recognize revenue on a percentage of completion
basis. In the future, we anticipate that an increasing percentage of our client
engagements will be subject to fixed-fee or other arrangements that are not
solely based on time and materials. We are generally reimbursed for reasonable
expenses under our contracts.

   Our revenue from foreign operations represents revenue for professional
services performed for clients outside the United States. Revenue from foreign
operations has made an increasing contribution to our total services revenue
and we anticipate continued growth in revenue from foreign operations. Foreign
operations represented approximately 35% of services revenues in 1998 and the
first three months of 1999 and 86% of income before income taxes in 1998 and
55% in the first three months of 1999. The higher relative profitability from
foreign operations principally arises because of better employee utilization
due to longer term projects of greater dollar value. Additionally, our foreign
operations incurred lower overhead costs as compared to our domestic operations
due to a lesser number of clients.

   Sales by Tanning Technology Europe Limited, a United Kingdom subsidiary, are
currently made in U.S. dollars or its functional currency of pounds sterling.
Historically, we have not experienced material fluctuations in our results of
operations due to foreign currency exchange rate changes.

   Revenue from a limited number of clients has comprised a very substantial
portion of our revenues and is expected to represent a very substantial portion
of our revenues in the foreseeable future. In 1997, our five largest clients
accounted for approximately 81% of our services revenue. In 1998, our five
largest clients accounted for approximately 70% of our services revenue. In the
first three months of 1999, our five largest clients accounted for
approximately 74% of our services revenue. Any cancellation, deferral or
significant reduction in work performed for these principal clients or a
significant number of smaller clients could have a material adverse effect on
our business, financial condition and results of operations. Historically, we
have been able to collect the applicable accounts receivable for work performed
up to the termination date from clients that have terminated projects. See
"Business--Clients."

   In 1998, we had revenue from both services and, to a lesser extent, product
sales. We completed the sale of the rights to one of our software products in
the third quarter of 1998. We have shifted our business focus to concentrate
solely on generating revenues from services.

   Project personnel costs represent our most significant expense and consist
primarily of salaries, bonuses and employee benefits for company personnel
dedicated to client assignments, and fees paid to subcontractors for work
performed on our projects. Subcontractors generally cost us more than our own
project personnel; consequently, we usually generate lower gross profit margins
by using subcontractors. Non-billable time incurred by our project personnel
resulting from start-up time for new hires and training time incurred to
upgrade the skills of existing staff may cause gross profit margins to
decrease. We plan to increase the number of our project personnel in order to
support our planned revenue growth.

                                       19

   Selling, marketing and administrative expenses consist primarily of
salaries, bonuses and employee benefits for non-project personnel, occupancy
costs, staff recruiting costs, travel expenses, depreciation expenses and
promotional costs. Our sales and marketing costs are expected to increase as a
percentage of revenue in the future as we enhance our selling effort. We also
expect to expand geographically by opening new offices in 1999 and 2000. This
will require us to purchase office equipment and computer and networking
equipment, both of which will increase our depreciation expenses.

   In anticipation of business growth, we expect to incur costs and expend
capital. We can give no assurances that we will continue to grow, or that we
will grow at a pace that will support these costs and expenditures. To the
extent revenues do not increase at a rate commensurate with these additional
costs and expenditures, our results of operations and liquidity could be
materially and adversely affected. In addition, we expect that our plans for
increases in expenses and capital expenditures over the next two and one-half
years to support our growth could negatively impact profitability.

   Our predecessor is Tanning Technology Group, LLC, which was formed on
February 8, 1995 as a result of the combination of four entities affiliated
with our co-founders, Larry G. Tanning, Bipin Agarwal, Toni S. Hippeli and
Stephen Brobst. Pursuant to a stock purchase agreement entered into with AEA
Tanning Investors Inc., the managing member of TTC Investors I LLC, TTC
Investors IA LLC, TTC Investors II LLC and TTC Investors IIA LLC (together with
AEA Tanning Investors Inc., the "TTC Investors Group"), our predecessor was
converted into a Delaware corporation and the TTC Investors Group purchased,
between January 1997 and June 1998, a total of 5,696,770 shares of our common
stock for an aggregate purchase price of $14.6 million.

Comparison of three months ended March 31, 1998 and 1999

 Net revenues

   Our net revenues increased $6.1 million, or 118%, to $11.3 million for the
first quarter of 1999 from $5.2 million for the first quarter of 1998. Included
in the first quarter of 1998 net revenue is $0.6 million of revenue from
product sales; there was no revenue from product sales in the first quarter of
1999. The increase in services revenue of 145% reflects increases in both the
size and number of client projects as well as higher average billing rates.
During the first quarter of 1999, as compared to the first quarter of 1998, the
number of clients we provided services for increased by 27%, and our average
revenue per customer increased by 93%. The increase in services revenue from
our foreign operations also significantly contributed to this increase in
revenue. The revenue from foreign operations increased $2.9 million, or 264%,
to $4.0 million for the first quarter of 1999 from $1.1 million for the first
quarter of 1998. Revenues from our five largest clients as a percentage of
total net revenues were 74% for the first quarter of 1999 and 77% for the same
period in 1998.

 Project personnel costs

   Our project personnel costs increased $2.6 million, or 90%, to $5.5 million
for the first quarter of 1999 from $2.9 million for the first quarter of 1998.
The increase in project personnel costs for the first three months of 1999 was
primarily due to an increase in project personnel from 79 at March 31, 1998 to
127 at March 31, 1999, as well as higher salaries. Our gross profit margin from
services has increased from 37% for the first quarter of 1998 to 51% for the
same period in 1999, principally as a result of higher average billing rates,
increased utilization of project personnel, and a shift in staffing mix to
using fewer subcontractors and more internal project personnel.

 Selling, marketing and administrative

   Our selling, marketing and administrative expenses increased $2.4 million,
or 102%, to $4.7 million for the first quarter of 1999 from $2.3 million for
the first quarter of 1998. The increase in selling, marketing and
administrative expenses was primarily the result of our decision to expand our
marketing effort to support revenue growth. Our sales, marketing and
administrative staff grew from 31 employees at March 31, 1998 to 50 employees
at March 31, 1999, and staffing expenses increased to $1.5 million. Selling,
marketing and administrative expenses decreased as a percentage of net revenues
from 45% in the first quarter of 1998 to 41% for the same period in 1999 due to
increases in revenues without a proportional increase in these expenses.

 Product development costs

   We incurred costs associated with software product sales during the first
quarter of 1998 of $820,000, or 16% of net revenues. No such costs were
incurred in 1999.

 Provision for (benefit from) income taxes

   Income tax expense represents combined federal, state, and foreign taxes.
Our income tax provision increased to $0.5 million on pre-tax profits of $1.3
million at the end of the first quarter of 1999 compared to a tax benefit of
$0.3 million on pre-tax losses of $0.8 million at the end of the first quarter
of 1998. The tax benefit was recorded in the first quarter of 1998 on the pre-
tax losses in anticipation of applying the tax benefit to future tax provisions
as we generate future profits. Our effective tax rate was 37% for the first
quarter of 1999 and for the same period in 1998.

Comparison of years ended December 31, 1997 and 1998

 Net revenues

   Our net revenues increased $7.2 million, or 28%, to $33.3 million in 1998
from $26.1 million in 1997. The increase in services revenue of 20% in 1998
reflects increases in both the size and number of client projects. During 1998,
as compared to 1997, the number of clients we provided services for increased
by 3%, and our average revenue per customer increased by 16%. Utilization and
revenues were adversely affected for the first half of 1998, principally as a
result of a significant project termination in the fourth quarter of 1997
following a change in the client's strategic plans due in part to regulatory
changes. This project termination negatively impacted our revenues by
approximately $5.7 million in the first half of 1998. As a result of this
termination, we generated $5.7 million less revenues from this client in the
first half of 1998 than we did in the second half of 1997, without a
proportionate decrease in project personnel costs. Utilization and revenues
improved in the second half of 1998 as new projects commenced, including
additional work for the same client. Our net revenues from foreign operations
increased $7.5 million, or 253%, from $3.0 million in 1997 to $10.5 million in
1998. In 1997, we earned revenues of $0.9 million from the sale of software
products compared to $3.0 million earned in 1998. The software sales in 1998
included the sale of the rights to certain software products. Revenues derived
from our five largest clients as a percentage of total net revenues were 65% in
1998 and 78% in 1997.

 Project personnel costs

   Project personnel costs increased $0.2 million, or 1%, to $14.9 million in
1998 from $14.7 million in 1997. The increase in project personnel costs in
1998 was due to an increase in project personnel from 81 at the end of 1997 to
107 at the end of 1998, which was nearly offset by a decrease in fees paid to
subcontractors. The gross profit margin from services increased from 42% in
1997 to 51% in 1998 as a result of improved utilization and a shift in staffing
mix to using fewer subcontractors and more internal project personnel.

 Selling, marketing and administrative

   Selling, marketing and administrative expenses increased $4.3 million, or
55%, to $12.2 million in 1998 from $7.9 million in 1997. Selling, marketing and
administrative expenses increased as a percentage of revenues from 30% in 1997
to 37% in 1998. These increases were primarily a result of our decision to
expand our selling and marketing group and the administrative staff to support
revenue growth. Also contributing to the increase in staffing expenses of $2.2
million were increases in occupancy costs of $0.6 million and increases in
depreciation expense of $0.8 million associated with fixed asset additions
during 1998. Our sales, marketing and administrative staff grew from 28
employees at the end of 1997 to 37 employees at the end of 1998.

 Product development costs

   We incurred costs associated with software product sales of $1.6 million in
1997 and $2.8 million in 1998, representing 6% of 1997 net revenues and 8% of
1998 net revenues. We have no plans to continue the development of software for
resale purposes.

 Sign-on bonus related to stock purchase agreement

   In conjunction with the stock purchase agreement entered into in early 1997,
we paid sign-on bonuses aggregating $2.1 million to some of our stockholders
and employees. This expense was a single occurrence in 1997 and was not
incurred in any other periods reported.

 Management fees--related parties

   We incurred management fees of $73,000 to members of our predecessor in
January 1997. No management fees were incurred after the formation of our
company in January 1997. These fees represent payment for services performed on
behalf of our predecessor. Subsequent to the formation of our company, the

                                       22
<PAGE>


payments made to members of our predecessor are reflected in salary expenses in
selling, marketing and administrative expenses, or as project personnel cost
for billable time incurred by these employees.

 Provision for (benefit from) income taxes

   Our provision for income taxes increased to approximately $1.4 million on
pre-tax profits of $3.7 million for 1998 compared to a tax benefit of
approximately $0.2 million on pre-tax losses of $0.1 million in 1997. Our
effective tax rate in 1998 was 37%. The 1997 tax benefit is the result of 11
months of net (loss) from operations before taxes of $0.4 million and the
implications of a change in that status after the merger of Tanning Technology
Group, LLC into Tanning Technology Corporation on January 31, 1997. No income
taxes were paid by Tanning Technology Group since members included their
distributive shares of revenue and deductions of the limited liability company
in their personal capacities, pursuant to Subchapter K of the Internal Revenue
Code.

Comparison of years ended December 31, 1996 and 1997

 Net revenues

   Our net revenues in 1997 increased $13.3 million, or 104%, to $26.1 million
from $12.8 million in 1996. The increase in services revenue of 98% in 1997
reflects increases in both the size and number of client projects. During 1997,
as compared to 1996, the number of clients we provided services for increased
by 3%, and our average revenue per customer increased by 92%. Our revenues from
foreign operations increased $2.5 million, or 549%, from $0.5 million in 1996
to $3.0 million in 1997. In 1997, we earned revenues of $0.9 million from the
sale of software products compared to $46,000 earned in 1996. Revenues derived
from our five largest clients as a percentage of total net revenues were 78% in
1997 and 80% in 1996.

 Project personnel costs

   Project personnel costs in 1997 increased $8.2 million, or 124%, to $14.7
million from $6.5 million in 1996. The increase in project personnel costs in
1997 was primarily due to an increase in project personnel from 40 at the end
of 1996 to 81 at the end of 1997. In addition, more fees were paid to
subcontractors during 1997. The gross profit margin from services revenue
decreased from 49% in 1996 to 42% in 1997 as a result of the shift in staffing
mix to using more subcontractors.

 Selling, marketing and administrative

   Selling, marketing and administrative expenses in 1997 increased $5.8
million, or 282%, to $7.9 million from $2.1 million in 1996. Selling, marketing
and administrative expenses increased as a percentage of net revenues from 16%
in 1996 to 30% in 1997. These increases were primarily a result of our decision
to expand our selling and marketing group and the administrative staff to
support revenue growth. Our sales, marketing and administrative staff grew from
9 employees at the end of 1996 to 28 employees at the end of 1997. In addition
to the increase in staff expense of $3.3 million, our facilities expense
increased $0.5 million and depreciation expense increased $0.2 million.

 Product development costs

   We incurred costs associated with software product sales of $0.4 million in
1996 and $1.6 million in 1997, representing 3% of 1996 net revenues and 6% of
1997 net revenues.

 Sign-on bonus related to stock purchase agreement

   In conjunction with the stock purchase agreement entered into in early 1997,
we paid sign-on bonuses aggregating $2.1 million in order to retain the members
and certain employees of our predecessor. This expense was a single occurrence
in 1997 and was not incurred in any other periods reported.

                                       23
<PAGE>


 Management fees--related parties

   We incurred management fees of approximately $902,000 in 1996 and $73,000 in
1997 to members of our predecessor, representing 7% of 1996 net revenues. These
fees represent payment for services performed on behalf of our predecessor. No
management fees were incurred after the formation of our company in January
1997, but payments to former members of our predecessor are reflected in salary
expenses in selling, marketing and administrative expenses, or as project
personnel cost for billable time incurred by these employees.

 Provision for (benefit from) income taxes

   Our income taxes benefit realized in 1997 was $0.2 million on pre-tax losses
of $0.1 million in 1997. No income taxes were paid by our predecessor, Tanning
Technology Group, LLC in 1996.

Quarterly results

   The following table presents our unaudited quarterly results of operations
for 1998 and the first quarter of 1999. We derived these data from unaudited
consolidated financial statements, and, in the opinion of management, they
include all necessary adjustments, which consist only of normal recurring
adjustments necessary to present fairly the financial results for the periods.
Results of operations for any fiscal quarter do not necessarily indicate what
results may be for any future period.

Stock-based compensation

   We have elected to follow Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees, and related interpretations in
accounting for its employee stock options. Under Accounting Principles Board
Opinion No. 25, because the exercise price of our employee stock options equals
the market price of the underlying stock on the date of grant, no compensation
expense is recorded. We have adopted the disclosure-only provisions of the
Financial Accounting Standards Board Statement of Financial Accounting
Standards No. 123.

Liquidity and capital resources

   Prior to January 1997, we financed our operations and investments in
property and equipment primarily through cash generated from operations,
unsecured and secured borrowings and capital lease financing. During 1997, we
issued common stock resulting in net proceeds to us of approximately $12.7
million. The proceeds were used to fund operations, purchase property and
equipment as well as to pay down $700,000 of outstanding debt during 1997.

   During 1998, we financed our operations and investments in property and
equipment primarily through cash generated from operations, the sale of common
stock and, to a lesser extent, borrowings. Outstanding debt of $1.1 million was
paid off in 1998 with the net proceeds from the sale of common stock of $1.9
million. At March 31, 1999, we had a bank note outstanding of approximately
$550,000, the proceeds of which were used to acquire office furniture and
fixtures. The note bears interest at 8.71% and principal and interest payments
are payable over a 60-month term.

   Cash and cash equivalents increased to $7.2 million at March 31, 1999 from
$1.6 million at December 31, 1996. The increase was primarily due to cash
provided as a result of the completion of our stock transactions and cash
provided by operations. We invest available cash in short-term liquid
investments.

   We anticipate that we will expend capital to develop the infrastructure
needed to support our future growth. As a result, we expect to use cash from
operations and the net proceeds from this offering to meet capital expenditures
and working capital necessary to support our growth. We currently have no
material commitments for capital expenditures. Based on our current business
plan, we believe that the cash provided from operations, cash on hand and our
net proceeds from this offering will be sufficient to meet our cash
requirements, including for working capital and capital expenditures, at least
through the end of 2000.

Qualitative and quantitative disclosures about market risk

   We provide our services to customers primarily in the United States, the
United Kingdom and Denmark. As a result, our financial results could be
affected by factors, such as changes in foreign currency exchange rates or weak
economic conditions in those foreign markets. Sales by Tanning Technology
Europe Limited, a United Kingdom subsidiary, are currently made in U.S. dollars
or its functional currency of pounds sterling. To the extent Tanning Technology
Europe has monetary assets and liabilities denominated in any currency other
than its functional currency, any significant variation in exchange rate
between the pound sterling and these other currencies could have a material
effect on our operating results. To the extent that we bill clients in a
currency other than their local currency, exchange rate fluctuations that
strengthen the currency in which we bill relative to their local currency could
make our services less competitive to such clients. To the extent we bill in
pounds sterling versus U.S. dollars, any depreciation of the pound against the
dollar would negatively affect our results of operations. Historically, we have
not experienced material fluctuations in our results of operations due to
foreign currency exchange rate changes.

Year 2000

   Until recently, computer programs were written to store only two digits of
date-related information in order to more efficiently handle and store data.
These programs were unable to distinguish properly between the year 1900 and
the year 2000, and as such, risk failure with the changing of the century. This
circumstance is frequently referred to as the "Year 2000 issue."

   We rely on information technology systems, applications and devices in
several aspects of our business, including service delivery, time reporting,
and financial accounting. In this regard, we have conducted an assessment of
our information technology systems and believe that significant changes will
not be necessary in order to achieve a Year 2000 date conversion with no effect
on customers or disruption of business operations. We have obtained written
and/or verbal confirmation, either directly or through published materials,
from our major third-party software providers that those applications currently
being used are Year 2000 compliant or that revised versions that are compliant
will become available. Internally-generated applications have been

                                       25
<PAGE>

largely tested and deemed compliant as well. Our computer hardware platforms,
principally servers, have been confirmed as Year 2000 compliant by the server
manufacturers, or have been appropriately upgraded in order to achieve
compliance. Based on currently available information, we believe that the total
expense related to these efforts will not have a material impact on our results
of operations.

   In addition to our internal systems, we also rely, directly and indirectly,
on the systems of business enterprises such as clients, suppliers, utilities,
creditors and financial institutions, both domestic and international. We plan
to obtain assurances from those material third-party vendors with which we
transact business that there will be no interruption of service as a result of
the Year 2000 issue. To the extent that assurances are not given, we intend to
devise contingency plans to mitigate the negative effects on our company in the
event the Year 2000 issue results in the unavailability of services. In
addition, the failure of the accounting systems of our clients due to the Year
2000 issue could result in a delay in the payment of invoices we have issued
for services rendered. A delay in payment of invoices could have a material
negative effect on us. Although we have not yet done so, we intend to inquire
of, and obtain assurances from, our major customers regarding the compliance of
their accounting systems. We also plan to assess risks related to the potential
failure of our non-information technology systems, which include, among other
things, our climate control systems and elevators. We expect to complete our
comprehensive risk assessment and related contingency plan in the third quarter
of 1999.

   Although our principal service offerings generally do not include Year 2000
remediation services, former, present and future clients could assert claims
against us related to the Year 2000 issue. There can be no assurance that all
information technology systems we have designed, developed, recommended or
deployed will be Year 2000 compliant. Any Year 2000-related failure of critical
client systems in which we were involved could result in claims being asserted
against us, regardless whether the failure is related to the services provided
by us. If asserted, liability that may result, and the time and resources used
in resolving these claims, could have a material adverse effect on us.

                                    BUSINESS

Overview

   We are an information technology services provider that architects, builds
and deploys enterprise solutions for companies throughout the world. We
specialize in large, complex, integrated solutions that incorporate online
transaction processing and very large databases. Internet technologies are a
central part of our solutions, enabling direct interaction among customers and
business partners on the World Wide Web, and among employees within
organizations on their private intranets. Our clients include Ameritech,
Blockbuster, BSkyB, E*Trade, Federal Express, Maersk Line, MCI WorldCom, R.R.
Donnelley Financial and U S WEST.

   Our key solutions are:

  .  electronic commerce solutions;

  .  enterprise customer relationship management solutions; and

  .  core operations solutions.

Industry background

   The explosive growth in demand for information technology service providers
in the 1990s has been driven by corporate recognition that information
technology can be used to achieve competitive advantage. GartnerGroup's
Dataquest, an information technology market research firm, estimates that the
worldwide information technology services market will grow from approximately
$361 billion in 1998 to approximately $722 billion by 2003.

   Within the overall information technology services market, some segments are
experiencing particularly rapid growth. For example, according to International
Data Corporation, an information technology market research firm, the market
for Internet services will grow from $7.8 billion in 1998 to $78.6 billion in
2003, representing a compound annual growth rate of 59%. In addition, AMR
Research, Inc., an information technology market research firm, predicts that
the market for customer relationship management services will grow from $404
million in 1997 to $4.0 billion in 2002, representing a compound annual growth
rate of 58%.

   With advances in the Internet and information technology, companies are
transforming the way they run their businesses and manage information. New
business models and innovative information technology solutions are emerging
that create business value by:

  .  compiling and coordinating customer information and contacts across the
     enterprise and all customer channels;

  .  profiling and scoring customers and performing predictive selling in
     real-time, which involves understanding each customer's needs and
     preferences so that the most appropriate products and services can be
     offered during a particular online interaction;

  .  integrating the business operations and content of business partners;

  .  coordinating the complex business transactions of the supply chain;

  .  providing dynamic personalized content to web page users; and

  .  enabling complex transaction processing systems that support core
     business operations.

   As part of this evolution of business models, today's electronic commerce,
customer relationship management and core operations solutions must be
architected and deployed to function reliably in an environment of rapidly
growing website traffic, numbers of customers, order volumes, customer service
inquiries and other business transactions. Advanced information technology
solutions must also be built with

                                       27
<PAGE>

the flexibility required to rapidly add features and functions, accommodate new
content and business partners and support modified business processes as the
business environment becomes more competitive. These advanced business
solutions must address the following technology challenges:

  .  dramatic increases in the volume of data and transactions processed;

  .  the emergence of rich data types, including text, images, video and
     sound;

  .  the evolution of batch to online processing to support real-time
     customer interactions;

  .  improved performance and response times to support real-time customer
     access from a variety of technology environments;

  .  improved reliability, accuracy and security of transactions;

  .  integration of legacy systems and databases across the enterprise; and

  .  high degrees of integration among applications, networks and platforms
     within a company as well as among diverse business enterprises.

   Many information technology service providers focus on the less technically
demanding areas of creative web design and simple transaction systems.
Moreover, they do not have the skills to design a solution with the required
scalability, flexibility and performance characteristics, or to deploy it in an
environment that may combine many generations of computing platforms and
technologies, all while facing the demands of real-time business operations.
Their solutions are often cobbled together from software packages, custom
software components and legacy systems, and fail to provide for the enormous
growth in transaction and data volumes that are experienced after going to
market. Forrester Research, an information technology research firm, cites
recent high-visibility web site outages at a number of electronic commerce
leaders in support of its conclusion that many of today's electronic commerce
solutions are unreliable, unscalable and deliver service levels that are not
adequate for online commerce.

   We believe that we are differentiated by our focus on, and expertise in, the
architecture, complex integration, high volume online transaction processing
capabilities and very large databases required to successfully deploy advanced
electronic commerce, customer relationship management and core operations
solutions. As a result, we believe that we are particularly well positioned to
benefit from the growing demand for these skills.

The Tanning Difference

   We believe that the following capabilities and characteristics differentiate
us from other information technology service providers.

 Large, complex solutions

   We specialize in architecting, developing and deploying large and complex
business-critical solutions that require high degrees of integration across
diverse portfolios of applications and technologies. Clients that seek to
transform their businesses with advanced electronic commerce, customer
relationship management and core operations solutions rely on the systems we
build to run their businesses without failure. Our solutions typically involve
ultra-high transaction rates (up to millions per hour) in online transaction
processing environments and very large databases (terabytes of information). We
believe that we are able to address our clients' greatest information
technology challenges because we are able to extend the accepted performance
and feasibility limits of leading-edge technologies. For many clients, the
systems we build are at the core of their efforts to capitalize on information
technology and the Internet.

 Business-value driven

   We focus on delivering solutions to our clients' business challenges, not
simply on technology. These solutions provide value to our clients by enhancing
their ability to communicate with their customers and

                                       28
<PAGE>


business partners, allowing our clients to offer new or enhanced products and
services, and providing them opportunities for revenue enhancement and cost
reductions. We align technology deployment with business objectives and
processes and plan deployments in phases to deliver business benefits rapidly.
Through extensive business analysis and work with clients to define and
articulate their business goals and constraints, we are able to discern a
project's critical business requirements before proceeding to technology
considerations.

 Architecture-based solutions

   Our architecture-based approach enables us to provide large and complex
integrated solutions that accommodate our clients' goals in a rapidly changing
business environment. Our overall architecture identifies the component and
technology frameworks required for the successful construction and deployment
of our solutions. Through rigorous systems analysis, we design solutions that
address requirements for:

  .  reliability, to ensure accurate processing and robust backup and
     recovery;

  .  scalability, to accommodate the rapid growth associated with electronic
     commerce, customer relationship management and core operations solutions
     under changing business conditions;

  .  full time availability (24 hours a day and 7 days a week);

  .  performance, to deliver the required end-user response times and
     transaction rates;

  .  flexibility, to accommodate new functions and interfaces;

  .  complex interfaces to, and coexistence with, legacy systems, software
     packages and departmental solutions in a heterogeneous technology
     environment;

  .  transaction and data integration, both within a company's business and
     among the company and its trading partners; and

  .  the ability to dynamically change features, services or product
     offerings based on real-time Internet customer interaction.

 Deployment-focused

   We deliver high-value business solutions that are deployment-focused, rather
than development-focused. Our deployment focus allows us to architect and
design solutions for successful roll-out to, and use by, the hundreds,
thousands and potentially millions of users of that system. We focus on
deployment to ensure that our solution is constructed for scalable performance,
reliable and consistent service levels, and high levels of flexibility and
longevity. We identify performance and service level requirements in the early
stages of the solution process, architect and design the system so that it will
meet these requirements and benchmark and develop proofs of concept to ensure
that our solution will work before construction of the application begins.
Benchmarking is a process of evaluating the performance of alternative system
configurations and components in order to determine which approach would best
meet the client's goals. We develop proofs of concept in order to demonstrate
the feasibility of our innovative architectures and combinations of components
as well as emerging technologies.

   The project lifecycles of many information technology service providers and
companies do not adequately address the constraints of interfaces or the
challenges of operating the system in the intended environment. Consequently,
clients often engage us to "rescue" systems that were unsuccessfully developed
or deployed. We believe our focus on deployment allows us to deliver successful
projects and business value for our clients and constitutes a significant
competitive advantage. As a result, since 1993, we have established a strong
track record of repeat business from large corporations throughout the world,
including Ameritech, Maersk Line, R.R. Donnelley Financial and BSkyB.

                                       29

 Experienced and talented staff

   Today's complex, data-intensive business solutions require broad, as well as
deep, technology skills to successfully tackle the technological challenges and
integration complexities typically encountered. We staff our projects based on
our philosophy that there is no substitute for experience, in contrast to the
common approach of relying on primarily inexperienced staff and building a
heavily "leveraged" staffing model that depends on methodology rather than
experience to guide the judgments and activities of project teams. Our
information technology professionals have an average of more than twelve years
of industry experience. Our breadth of skills comes from the experience our
staff has with four generations of technology--mainframe and parallel
processing environments, minicomputers, client/server architectures and web
technology architectures. Our depth of skills began with our early work in
benchmarking large applications and databases that required multi-tier software
architecture, in which the key layers of an application system are separated
and optimized independently to improve performance, scalability and
reliability.

   Our employees have expertise in a broad range of competencies, including
project management, business analysis, object modeling, architecture, software
development, database modeling and administration, quality assurance,
integration and testing, architecture and performance tuning, and system and
network management. We believe our staff is recognized in the industry for its
rich capabilities in building applications that deal with high transaction
volumes and very large database requirements.

 Flexible pricing

   We offer clients a choice of the most appropriate pricing model for a
particular engagement. Many of our engagements are based on time and materials
pricing, particularly in situations where the parameters of a project or
particular phase of a project cannot yet be specified. In other situations, a
client may prefer a fixed price/fixed time contract in order to cap its costs
while retaining guaranteed delivery of a solution. We offer flexible pricing
options to accommodate our clients' goals as well as to provide the most
appropriate pricing model for the project.

Strategy

   Our strategy for growth centers around scaling our capabilities in
architecting, developing and deploying large, complex, business-critical
enterprise solutions. We will continue to identify areas of growing demand for
these types of solutions and differentiate ourselves based upon our experience,
capabilities and references. These areas may take the form of geographic
regions, industries or solution areas.

   To achieve our objectives, we plan to:

  .  Maintain our leading edge capabilities

       We believe that our clients choose to work with us because of our
    reputation for successfully handling information technology's most
    challenging assignments. A key source for new and advanced capabilities
    is our experience in developing solutions that are innovative, and of
    industry-leading scale and complexity. For example, we deployed a
    solution for Blockbuster that assembled customer data and account
    activity information for over 40 million customers and 6,000 stores.
    The solution involved terabytes of information and difficult
    integration issues, including hardware design and configuration,
    database architecture, fault tolerance and operations support. We plan
    to continue to actively manage our portfolio of client engagements to
    ensure that we work on complex assignments that will allow us to refine
    and advance our capabilities on an ongoing basis. We also believe that
    our reputation for working on the industry's most difficult assignments
    will assist us in continuing to recruit professionals who further add
    to our skills and knowledge base. In addition, we intend to continue
    and expand our practice of coordinating with our business and
    technology partners to share expertise and innovations.

                                       30
<PAGE>

  .  Expand our solutions and service offerings

       We intend to increase our focus on rapidly growing solution areas in
    which we believe our expertise is relevant. For example, building off
    of our successful engagements with Federal Express and Blockbuster, we
    intend to develop an enhanced presence in the area of supply chain
    management. We also intend to expand our service offerings in areas
    such as business consulting, process innovation and creative design. In
    addition, our strategy includes expanding our solutions and service
    offerings and gaining access to new technologies through strategic
    acquisitions and investments when attractive opportunities arise.
    Although we believe that the areas in which we currently specialize are
    among the fastest growing and critical in the information technology
    industry, we believe that our ability to provide expanded integrated
    service offerings will allow us to establish relationships with a
    greater range of clients who have a need for our expertise and to
    engage them earlier in the determination of their business needs.

  .  Expand our vertical industry focus

       We intend to organize our sales and marketing efforts in the
    industries in which there is significant potential demand for our
    services and expertise. We intend to organize industry practice groups
    in sales and marketing because we believe that businesses seek out
    service providers who are familiar with the types of issues faced by
    their industry and who are conversant with the language of the
    industry. Currently, we are formally organized in telecommunications,
    an industry in which we have a significant amount of experience. We
    plan to organize industry practice groups in other high growth
    industries such as media and entertainment, financial services,
    healthcare, and logistics and transportation as our business in these
    industries grows.

  .  Expand our relationships with existing clients and develop new clients

       We intend to base our growth on long-term client relationships,
    rather than on a project-by-project approach. Our client relationship
    philosophy is that clients will choose to do business with us based on
    the quality of our work, the value of our advice and solutions, and the
    level of trust and respect that develops over time. Expanding our
    existing client relationships will allow us to jointly plan future
    projects and, in particular, develop large, multiyear engagements. This
    will improve our ability to forecast projects, thereby helping us to
    manage growth. We will continue to assign each of our clients a
    relationship manager who will be responsible for ensuring that the
    client is satisfied with the services we are providing. Relationship
    managers work with their clients in an advisory capacity to clarify and
    prioritize their business needs and secure additional high value
    projects, based upon their in-depth knowledge of each client's business
    and information technology needs.

       We also intend to develop new clients through multiple channels
    including our sales force, industry analysts, marketing events and
    public relations, as well as through relationships with hardware and
    software suppliers. Our dedicated sales and marketing team will allow
    us to focus on solutions common across industries and will seek out
    opportunities for entry-level service offerings such as assessments and
    "rescue missions." We will also expand our relationships with hardware
    and software suppliers such as IBM, Sun Microsystems, Hewlett Packard
    and others to identify project opportunities consistent with our
    capabilities and to provide us with client leads.

  .  Continue to attract and retain experienced, knowledgeable professionals

       We have consistently attracted and retained leading information
    technology talent interested in solving our industry's toughest
    challenges. We plan to continue to recruit experienced staff from
    consulting companies, corporate information technology organizations
    and the benchmarking and product development centers of the industry's
    leading hardware and software product companies. We expect that our
    talented staff will also continue to provide us with employee
    referrals, which have accounted for over 50% of our new recruits in the
    last three years. We intend to continue to promote

                                       31
<PAGE>


    a company culture that has allowed us to maintain an annual retention
    rate of technical personnel in excess of 92% over the last three years,
    which we believe is a key competitive advantage in an industry beset by
    a talent shortage.

  .  Serve clients globally

       We plan to expand our services and solution capabilities to client
    locations around the world. Our expansion will be revenue-based--we
    intend to open additional offices primarily where we have existing
    clients in the geographic region. We believe this will enable us to
    develop closer relationships with and provide more convenience to our
    clients who are increasingly seeking service providers with global
    presence and experience deploying solutions that address issues of
    multiple currencies and languages, infrastructure diversity and around-
    the-clock operations. We also expect that global expansion will allow
    us to capitalize on high growth geographic regions and diversify our
    revenue base.

  .  Expand our infrastructure for growth

       We plan to continue our commitment to growth by making investments
    in recruitment and retention, staff development, sales and marketing,
    management information systems and other areas of infrastructure. We
    have created a "Knowledge Net" on our internal computer network in
    order to accumulate and make readily available to our employees (1)
    expertise we have derived from our engagements, (2) best practices and
    (3) a repository of information that can be used in sales, marketing
    and service delivery. We intend to expand our formal employee
    orientation program and to assist our technical staff in managing their
    career paths. We also intend to improve our scalable global information
    systems, in order to more effectively manage client lead generation and
    tracking, sales forecasting, project profitability and employee
    utilization. We believe that these investments will provide a
    foundation for the continued expansion of our client and revenue base.

The Tanning Approach

   The Tanning Approach flows directly from the Tanning Difference--we are
business-value driven, architecture-based and deployment-focused. We emphasize
rigorous business alignment during our assessment and architecture phases, and
address critical performance and operational requirements during our
architecture and development phases to ensure successful system deployment and
operation.

   The Tanning Approach is composed of distinct phases, and each phase can be
adapted to the unique needs and requirements of an individual project. Each
phase also builds upon the deliverables of the previous phase. Our approach is
designed to deliver business value rapidly, by delivering the results in
several successive installments, rather than committing to extended projects
where business deliverables are produced only at the end of a protracted period
of time. This approach is also flexible, because not all phases are required by
every project. The following diagram illustrates the Tanning Approach.




                  [THE FOLLOWING IS REPRESENTED BY A GRAPHIC]

                              System

                            Integration


   Our clients typically engage us in one of two alternative project scenarios.
The first is a strategic initiative in which we are engaged to help architect,
develop and deploy a new high-value business solution. Strategic

                                       32
<PAGE>

initiatives begin with an assessment and continue sequentially through the
phases of the Tanning Approach. The second is a "rescue mission," where the
client engages us to turn around a troubled or failed project. Typically, in
this type of situation, the system has been or is being constructed but is not
meeting the client's expectations. Rescue missions begin with an assessment,
but proceed through a modified version of the Tanning Approach that builds on
the useful work completed by the prior project effort, and proceeds to
emphasize those elements of the Tanning Approach that will successfully deploy
an improved solution. In a rescue mission, we will leverage the existing
information about the system, perform design reviews, and provide deployment
and operational support services to get the system into production.

 Assessment

   Every project begins with an assessment. Each assessment results in a clear
definition of the client's business problem, a set of recommendations and an
outline of the next steps as well as a statement of the project's contemplated
business benefits. The assessment and the presentation of its results to our
client is a key entry level service offering that enables us to demonstrate our
capabilities and serves as a platform for establishing a more extensive project
engagement and a continuing client relationship.

   Assessments typically address one or more of the following:

   .  business case and business requirements;

   .  enterprise architecture;

   .  systems architecture;

   .  application design;

   .  development processes;

  .  integration testing processes;

  .  application migration considerations;

  .  deployment considerations; and

  .  operational readiness considerations.

 Enterprise/system architecture

   A well-defined architecture provides a critical foundation for the
successful definition, development, deployment and operation of information
technology systems. Enterprise architectures address the entire portfolio of
applications and technologies across the enterprise, while system architectures
address the more focused scope of a specific application or system. The
architecture is particularly critical when an iterative, phased approach for
development and deployment is used because it provides a rational framework for
each of the components and subsystems, as they are developed and deployed. A
well-defined architecture and technical framework greatly reduces the effort
and risk associated with the integration of components and subsystems because
each of the subsystems is integrated using proven interfaces and methods. We
deliver the architecture phase of the Tanning Approach to our clients either as
part of a specific application or solution project, or alternatively, as a
stand-alone engagement that addresses the entire enterprise architecture or
specific components of it.

   An architecture is also more than just an inventory of vendors and
standards. It specifies all of the subsystems and components required to deploy
an effective information technology system. Further, this architecture defines
the dependencies and interfaces between the components and the functional,
operational and performance requirements of each subsystem and component.

   The architecture phase of the Tanning Approach also focuses on identifying
and mitigating the major risks involved in the project. It can include building
proofs of concept for high-risk system components and new

                                       33
<PAGE>

technologies. Benchmarking may be performed to identify and resolve major
system bottlenecks for performance. Prototypes may also be developed to
visualize key user scenarios, functions or processes to make sure that there is
consensus in their definition and that the project is resolving the key
business issues and delivering the expected business value. Prototypes are also
used to validate and test critical components of the architecture. This phase
also involves detailing aspects of the architecture that need further
definition before beginning component development.

 Phased development and product integration

   This stage of the Tanning Approach is characterized by phased design,
development and testing of various individual components (including user and
system interfaces) of the final business solution. If software packages or
technology components will be integrated into the solution, then this phase
also includes their integration. The phased system components are typically
organized into releases that deliver meaningful business value in rapid time
frames. We use standard methodologies and tools to conduct and document the
design and development of system releases. Each system release goes through
integration testing, as part of our quality assurance, to ensure that the
components function properly as a complete system.

 Deployment services

   The deployment phase of the Tanning Approach is designed to ensure the
successful deployment of the completed software into the client's computing
environment where it will support real-world business activities. Deployment
addresses issues related to systems management, data center operations and
performance testing to ensure that the system will provide the performance
demanded by business users and defined in the system service level agreements.
Our deployment phase typically includes a period where any systems or
components being replaced are run in parallel with the new system to ensure
proper operation before converting to the exclusive use of the new system.

 Operational support services

   The operational support phase of the Tanning Approach gives clients the
opportunity to engage us for ongoing maintenance and support of applications
and systems. We can also provide both remote and local system administration to
ensure proper operation, maintenance and enhancement of systems.

Challenge:   Help Blockbuster understand its    Solution:    We redesigned Blockbuster's
             customer demographics and                       existing enterprise architecture
             purchase patterns in order to                   and created a new system that
             stock movies according to                       allows Blockbuster to assemble

                                                             Blockbuster to measure demand for

Challenge:   Assist E*Trade in building a       Solution:    We designed international
             global brand by creating a                      extensions to E*Trade's domestic
             standardized platform for its                   trading system, enabling support
             international expansion                         for multiple languages and the

                                                             We deployed this system in Sweden

Challenge:   Help Maersk Line improve customer  Solution:    We developed a solution for
             service across over 400 offices                 Maersk Line that enabled them to
             in                                              exploit best practices in
             nearly every country around the                 customer service globally. The
             world                                           solution was architected to allow

Clients

   The following is a representative list of our clients for 1998 and the
current year.

             The Hartford     U S WEST
</TABLE>

   In 1997, our five largest clients accounted for approximately 81% of our
services revenue, with Ameritech accounting for approximately 41% of our
services revenue and Oxford Health Plans accounting for approximately 23% of
our services revenue. In 1998, our five largest clients accounted for
approximately 70% of our services revenue, with Maersk Line accounting for
approximately 31% of our services revenue, U S WEST accounting for
approximately 12% of our services revenue and E*Trade and CSX Technology each
accounting for approximately 10% of our services revenue. In the first three
months of 1999, our five largest clients accounted for approximately 74% of our
services revenue, with Maersk Line accounting for approximately 31% of our
services revenue and U S WEST, E*Trade, and Ameritech each accounting for
approximately 12% of our services revenue. We believe that we will continue to
derive a significant portion of our revenue from a limited number of clients.
Any cancellation, deferral or significant reduction in work performed for these
principal clients or a significant number of smaller clients could have a
material adverse effect on our business, financial condition and results of
operations.

Marketing and sales

   We market and sell our services through multiple channels including our
sales force, long-term client relationships, relationships with industry
analysts, marketing events and public relations. We also cultivate
relationships with hardware and software suppliers such as IBM, Sun
Microsystems, Hewlett Packard and others to identify project opportunities
consistent with our capabilities and to provide us with client leads. For
example, some of these suppliers maintain sales forces in the hundreds and
thousands with a significant

                                       36
<PAGE>


presence at large companies around the world. These suppliers also introduce us
to clients and assist in our efforts to secure business opportunities. In
return, we provide them with solution capabilities, which are of high
importance to their clients.

   While our marketing channels and relationships with hardware and software
suppliers are used to generate business with new accounts, we also have an
organization of relationship managers who are responsible for managing
relationships with existing clients. Relationship managers seek to ensure
client satisfaction, the successful delivery of projects and are able to
identify additional opportunities for our services at a client site.

Competition

   The information technology services business is intensely competitive and
subject to rapid technological change. We expect the competition to continue
and intensify. Our competitors fall into four major categories:

  .  large information technology consulting services providers, such as
     Andersen Consulting, KPMG, PricewaterhouseCoopers, IBM, EDS and CSC;

  .  mid-tier information technology services providers, such as Cambridge
     Technology Partners and Sapient;

  .  Internet professional service providers, such as Modem Media . Poppe
     Tyson, US Interactive, Proxicom, Viant and Scient; and

  .  internal information technology departments of current and potential
     clients.

   Many of our competitors have longer operating histories and client
relationships, greater financial, technical, marketing and public relations
resources, larger client bases and greater brand or name recognition than we
have.

   In addition, there are low barriers to entry into our business. We do not
own any technologies that preclude or inhibit competitors from entering our
industry. Existing or future competitors may independently develop and patent
or copyright technologies that are superior or substantially similar to our
technologies. The costs to develop and to provide information technology
services are relatively low. Therefore, we expect to continue to face
additional competition from new entrants into our industry.

   We believe that the principal competitive factors in our business, in
relative importance, are:

   .  client value and service;

   .  the reputation and experience of professionals delivering solutions;

   .  the success and reliability of the delivered solution;

   .  technical knowledge and creative skills; and

   .  the ability to attract and retain professionals.

We believe that we presently compete favorably with respect to each of these
factors. The market for our services is evolving, however, and we cannot be
certain that we will compete successfully in the future.

Employees

   As of March 31, 1999, we had 177 employees. We believe our relationship with
our employees is satisfactory. None of our employees is represented by a union.
Generally, our employees are retained on an at-will basis.


                                       37

Intellectual property rights

   Our success is dependent, in part, upon our proprietary processes,
components, and other intellectual property rights. We do not have any patents
or patent applications pending. We rely on a combination of trade secret,
nondisclosure and other contractual agreements, and copyright and trademark
laws, to protect our proprietary rights. Existing trade secret and copyright
laws afford us only limited protection. We enter into confidentiality
agreements with our employees, generally require that our consultants and
clients enter into similar agreements, and limit access to and distribution of
our proprietary information. In addition, we have entered into non-competition
agreements with certain of our key employees. There can be no assurance that
the steps we have taken in this regard will be adequate to deter
misappropriation of our proprietary information or that we will be able to
detect unauthorized use and take appropriate steps to enforce our intellectual
property rights.

   A portion of our business involves the development of software applications
for specific client engagements. Ownership of client-specific software is
generally retained by the client, although we retain some rights to the
applications, processes and intellectual property developed in connection with
client engagements.

Facilities

   Our principal headquarters is located in Denver, Colorado and comprises
23,598 square feet. The lease for our headquarters expires in April 2000 and we
have the option to extend the term to April 2005. We are opening an
approximately 50,000 square-foot new headquarters in Denver, Colorado in the
third quarter of 1999. We also have offices in Phoenix, Arizona; Stamford,
Connecticut; Tampa, Florida; Atlanta, Georgia; Boston, Massachusetts; Portland,
Oregon; Chertsey, England; and Hyderabad, India. We do not own any real estate.
We do not consider any specific leased location to be material to our
operations, and we believe that equally suitable alternative locations are
available in all areas where we currently do business.

Legal proceedings

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

Board of directors

   Our board of directors is currently composed of six directors. We intend to
expand the board of directors to seven directors upon completion of this
offering. The new director will be Michael E. Shanahan.

   We intend to amend our certificate of incorporation to divide the board of
directors into three classes: Class I, whose terms will expire at the annual
meeting of stockholders to be held in 2000, Class II, whose terms will expire
at the annual meeting of stockholders to be held in 2001, and Class III, whose
terms will expire at the annual meeting of stockholders to be held in 2002. The
initial Class I directors will be Toni S. Hippeli and Michael E. Shanahan. The
initial Class II directors will be Christopher P. Mahan and Joseph P. Roebuck.
The initial Class III directors will be Larry G. Tanning, Bipin Agarwal and
Henry F. Skelsey. At each annual meeting of stockholders beginning in 2000, the
successors to directors whose terms will then expire will be elected to serve
from the time of election and qualification until the third annual meeting
following election.

   In addition, our certificate of incorporation will provide that the
authorized number of directors may be changed only by resolution of the board
of directors. Any additional directorships resulting from an increase in the
number of directors will be distributed among the three classes so that, as
nearly as possible, each class will consist of one-third of the total number of
directors.

Committees of the board of directors

   Our committees consist of an audit committee and a compensation committee.
The audit committee recommends the annual appointment of our auditors with whom
the audit committee reviews the scope of audit and non-audit assignments and
related fees, accounting principles we use in financial reporting, internal
auditing procedures and the adequacy of our internal control procedures. During

their services as directors. Directors who are not our employees will not
receive a fee for attendance in person at meetings of our board of directors or
committees of our board of directors, but they will be reimbursed for travel
expenses and other out-of-pocket costs incurred in connection with the
attendance of meetings. Directors who are not our employees or employees of AEA
Investors Inc. will be eligible to receive options to purchase our common stock
in connection with their appointment to our board of directors.

    become time-vested on December 1, 1999, 2000, 2001 and 2002, respectively.
    Up to 19,643 of the shares subject to the option vest based upon the
    attainment of performance goals in 2000. Of those shares that become
    performance vested, one-fourth become time-vested on December 1, 2000,
    2001, 2002 and 2003, respectively. Up to 52,382 of the shares subject to

    those shares that become performance-vested, one-fourth become time-vested
    on December 1, 2001, 2002, 2003 and 2004, respectively. Whether or not
    vested based on the attainment of performance goals, all of the
    performance-based options will become exercisable based on continued
    employment on December 1, 2003.
(5) In connection with Mr. Stack's resignation, Mr. Stack will continue to vest
    in these options through November 17, 2001, on the condition that he
    complies with various non-competition, non-solicitation and related
    covenants during the vesting period.

(6) In connection with Mr. Stack's resignation, these options were canceled.

Aggregate option exercises in fiscal 1998 and fiscal year-end option values

   The following table sets forth information concerning the value of
unexercised in-the-money options held by the Named Executive Officers as of
December 31, 1998.

   There was no public trading market for our common stock at December 31,
1998. Accordingly, these values of exercisable and unexercisable in-the-money
options have been calculated on the basis of the fair market value of our
common stock at December 31, 1998 ($3.82 per share) as determined by our board
of directors, less the applicable exercise price per share multiplied by the
number of shares underlying the options.

Tanning Technology Corporation Amended 1999 Employee Stock Purchase Plan

   On      , 1999, our board of directors adopted and our stockholders approved
the Tanning Technology Corporation Amended 1999 Qualified Stock Purchase Plan,
which will become effective upon completion of this offering. We intend to
administer the plan so that it qualifies as an employee stock purchase plan
under Section 423 of the Internal Revenue Code. The maximum number of shares of
Common Stock available for awards under the 1999 Stock Purchase Plan is    .

   The purpose of the plan is to strengthen our company by providing our
employees and our subsidiaries' employees the opportunity to acquire a
proprietary interest in our company through the purchase of shares of our
common stock at a discount. These purchases will be funded through regular
payroll deductions of up to 15% of a participant's gross cash wages for each
pay period during an offering period. Each full-time employee may participate
in the plan. An offering period to purchase shares of our common stock will
begin on the date on which Tanning and the underwriters agree on the price per
share in this offering and end on December 31, 1999. Thereafter, offering
periods will commence on each January 1 and July 1.

   On the first day of each offering period, each participant is deemed to have
been granted an option to purchase a number of shares of common stock which
will have an aggregate purchase price equal to a percentage designated by the
participant (between 1 and 15 percent) of his gross cash wages during such

                                       47
<PAGE>


offering period. The purchase price for such shares will be the lower of 85% of
the fair market value of the shares on the first day and the last day of the
offering period. The maximum number of shares of common stock that a
participant may purchase during an offering period is     . Each participant
will automatically purchase shares on the last day of the offering period.

   A participant may reduce the percentage of payroll deductions once during an
offering period. A participant may discontinue payroll deductions at any time
during an offering period. If a participant discontinues payroll deductions, he
may request that amounts previously withheld be returned without interest.

   The plan will be administered by the compensation committee of the board of
directors. Its determinations will be conclusive and binding. The board of
directors may amend or terminate the plan at any time; however, no such
amendment or termination may adversely effect outstanding options. Termination
of the plan will cause the termination of the then current offering period.

Tanning Technology Corporation 1999 Stock Option Plan

   On       , the board of directors adopted and our stockholders approved our
1999 Stock Option Plan, which will become effective upon completion of this
offering.

   The 1999 Stock Option Plan provides for the granting of incentive stock
options to our employees and nonqualified stock options to our employees,
consultants and directors. The maximum number of shares of common stock
available for awards under the 1999 Stock Option Plan is     .

   The following is a summary description of the 1999 Stock Option Plan.

 Overview

   The 1999 Stock Option Plan provides our employees, consultants and directors
with an opportunity to purchase our shares. The purpose of the plan is to
retain the services of the optionees and to incentivize them to devote maximum
efforts to our success and to align their interests with those of our
stockholders.

 Administration

   The 1999 Stock Option Plan will be administered by a committee of the board
of directors that consists of at least two non-employee members. The
compensation committee of the board of directors is expected to serve as the
committee.

   Generally, the committee (1) will select those persons to whom options will
be granted, and (2) will determine the terms and conditions of options,
including the purchase price per share and the vesting provisions. The
committee will interpret the plan and its determinations will be final. The
committee will have the authority to make amendments or modifications to
outstanding options consistent with the plan's terms.

 Eligible individuals

   Any of our current or future employees, consultants or directors will be
eligible to participate in the 1999 Stock Option Plan. There are approximately
   individuals currently eligible to participate in the plan.

 Shares subject to the 1999 Stock Option Plan

   The maximum number of shares available for the granting of options under the
1999 Stock Option Plan is     . The maximum number of shares that an eligible
individual may receive in respect of options granted in any calendar year is
   . If any option is exercised by tendering shares, either actually or by
attestation as full or partial payment of the exercise price, the maximum
number of shares available under the plan will be increased by the number of
shares so tendered. Whenever any outstanding option expires, is canceled, is
settled in cash or is otherwise terminated without having been exercised, the
shares allocable to the expired, canceled, settled or otherwise terminated
portion of the option may again be the subject of an option grant.


                                       48
<PAGE>

   Options will be designated as either incentive stock options, or ISOs, which
are intended to qualify for special tax treatment, or nonqualified stock
options. No employee may receive ISOs in respect of more than 1,000,000 shares
of common stock. The per share exercise price of any option will be fixed by
the committee at the time the option is granted. The per share exercise price
of any ISO may not be less than 100% of the fair market value on the date the
option is granted or 110% in the case of an ISO granted to a 10% stockholder.
Each option is exercisable at such dates and in such installments as determined
by the committee. Each option will be for a term will be determined by the
committee.

   Except as otherwise determined by the committee, options will not be
transferable except by will or the laws of descent and distribution.

   The purchase price for shares acquired pursuant to the exercise of an option
must be paid in full concurrently with the exercise of the option. The purchase
price may be paid in cash, or as otherwise determined by the committee.

   In the event of a merger of Tanning with or into another corporation, or the
sale of substantially all of our assets, each outstanding option shall be
assumed or an equivalent option substituted by the successor corporation or a
parent or subsidiary of the successor corporation; provided, however, that the
options shall remain subject to all of the conditions, restrictions and
performance criteria which were applicable to such options prior to such
assumption or substitution. In the event that the successor corporation refuses
to assume the option or substitute an equivalent option, the optionee shall
have the right to exercise the option as to all of the shares subject to the
option, including shares as to which it would not otherwise be exercisable. If
an option is exercisable in lieu of assumption or substitution in the event of
a merger or sale of assets, our company's secretary shall notify the optionee
that the option shall be fully exercisable for a period of fifteen (15) days
from the date of such notice, and the option shall terminate upon the
expiration of such period. For the purposes of this paragraph, the 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 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 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).

 Termination of employment

   Each option agreement will set forth the terms and conditions applicable to
the option upon a termination of employment of the optionee.

 No additional rights

   An optionee will not have any rights to the underlying shares until the
option is properly exercised. The 1999 Stock Option Plan does not give any
person any rights with respect to shares except as provided in the plan. The
plan does not limit in any way our right to terminate anyone's employment. It
is also not evidence of any agreement or understanding that we will employ any
person at any particular rate of compensation or for any particular period of
time.

 Income tax withholding

   When an optionee recognizes taxable income in connection with the receipt of
shares under the 1999 Stock Option Plan, the optionee must pay us an amount
equal to the federal, state and local income taxes and other amounts as may be
required by law to be withheld by us prior to the issuance of such shares. We
may deduct from any payment an amount equal to the withholding taxes in
satisfaction of an optionee's obligation to pay withholding taxes. If permitted
by the committee, in satisfaction of the obligation to pay withholding taxes,
the optionee may elect to have withheld a portion of the shares then issuable
to him or her having an aggregate fair market value equal to the withholding
taxes.

                                       49
<PAGE>

 Adjustments upon change in capitalization

   In the event of a change in capitalization, the committee will adjust the
maximum number and class of shares or other stock or securities with respect to
which options may be granted under the 1999 Stock Option Plan or to any
eligible individual in any calendar year and the number and class of shares or
other stock or securities which are subject to outstanding options and the
purchase price therefor.

 Effect of liquidation

   In the event of our liquidation, the 1999 Stock Option Plan and the related
options issued will continue in effect in accordance with their respective
terms. Following such a liquidation, each optionee will be entitled to receive
in respect of each share subject to any outstanding option, upon the exercise
of the option, the same number and kind of stock, securities or other
consideration that each holder of a share was entitled to receive in the
liquidation in respect of a share; provided that such stock, securities or
other consideration will remain subject to all of the provisions which were
applicable to the option prior to such liquidation.

 Pooling transactions

   In the event of a transaction which is intended to constitute a pooling
transaction, we may take such actions as are specifically recommended by an
independent accounting firm to the extent reasonably necessary to assure that
the transaction will qualify as a pooling transaction. These actions may affect
the terms and conditions of awards under the 1999 Stock Option Plan.

 Multiple agreements

   The terms of any option under the 1999 Stock Option Plan will be set forth
in an agreement between us and the optionee.

 Amendment and termination

   The 1999 Stock Option Plan terminates on the day preceding the tenth
anniversary of its adoption. The board of directors or the committee may at any
time and from time to time amend, modify, suspend or terminate the 1999 Stock
Option Plan. However, no such amendment, modification, suspension or
termination may adversely alter any outstanding options without the consent of
the optionee. In addition, amendments may require stockholder approval.

 Federal income tax consequences

   In general, an optionee will not recognize taxable income upon the grant or
exercise of an ISO and we will not be entitled to any business expense
deduction. However, upon the exercise of an ISO, the excess of the fair market
value on the date of exercise of the shares received over the exercise price of
the option will be treated as an adjustment to alternative minimum taxable
income (unless the shares are sold in the same taxable year as exercise). In
order for the exercise of an ISO to qualify as an ISO, an optionee generally
must be an employee of Tanning or a subsidiary from the date the ISO is granted
through the date three months before the date of exercise or one year preceding
the date of exercise in the case of an optionee whose employment is terminated
due to disability. The employment requirement does not apply where an
optionee's employment is terminated upon death.

   If an optionee held the shares acquired upon exercise of an ISO for more
than two years after the date of grant and for more than one year after the
date of exercise, when the optionee disposes of the shares, the difference, if
any, between the sales price of the shares and the exercise price of the option
will be treated as long-term capital gain. If an optionee disposes of the
shares prior to satisfying these holding period requirements, the optionee will
recognize ordinary income at the time of the sale, generally in an amount equal

                                       50
<PAGE>

to the excess of the fair market value of the shares at the time of exercise
over the exercise price of the option. The balance of any gain realized will be
short-term or long-term capital gain. If the optionee sells the shares prior to
satisfying the holding period requirements at a price below fair market value
at the time the option was exercised, the amount of ordinary income will be
limited to the amount realized on the sale over the exercise price of the
option. In general, if we comply with applicable income reporting requirements,
we will be allowed a business expense deduction to the extent an optionee
recognizes ordinary income.

   In general, an optionee who receives a nonqualified stock option will not
recognize income at the time of the grant of the option. Upon exercise of a
nonqualified stock option, an optionee will recognize ordinary income in an
amount equal to the excess of the fair market value of the shares on the date
of exercise over the exercise price of the option. The basis in the shares
acquired upon exercise of a nonqualified stock option will equal fair market
value of such shares at the time of exercise. The holding period of the shares
for capital gain purposes will begin on the date of exercise. In general, if we
comply with applicable income reporting requirements, we will be entitled to a
business expense deduction in the same amount as the optionee recognizes
ordinary income. In the event of a sale of the shares received upon the
exercise of a nonqualified stock option, any appreciation or depreciation after
the exercise date generally is taxed as capital gain or loss. However, any gain
will be subject to reduced tax rates if the shares were held for more than
twelve months.

   This discussion assumes that at the time of exercise, the sale of the shares
would not subject an optionee to liability under Section 16(b) of the Exchange
Act. Special rules may apply with respect to persons who may be subject to
Section 16(b). Optionees who are or may become subject to Section 16(b) should
consult with their own advisors.

 Excise taxes

   Under certain circumstances, the accelerated vesting or exercise of options
in connection with a change in control of Tanning may be deemed an "excess
parachute payment" for purposes of the golden parachute tax provisions of
Section 280G of the Internal Revenue Code. To the extent it is so considered,
an optionee may be subject to a 20% excise tax and we may be denied a tax
deduction.

                              CERTAIN TRANSACTIONS

Stock Purchase Agreement, Shareholder Agreement and Registration Rights
Agreement

   Tanning, Tanning's founders, and the TTC Investors Group are parties to a
stock purchase agreement dated as of December 24, 1996, as amended. Under this
agreement, the TTC Investors Group purchased an aggregate of 5,696,770 shares
of our common stock for an aggregate consideration of $14.6 million.

   The parties to the stock purchase agreement have entered into an amended and
restated shareholder agreement dated July  , 1999, which provides, among other
things:

  .  the TTC Investors Group may nominate one director to our board of
     directors;

  .  Courtney Rose Corporation, which is controlled by Larry G. Tanning, and
     WinSoft Corporation, which is controlled by Bipin Agarwal, each may
     nominate one director to our board of directors;

  .  the TTC Investors Group may appoint one member to each of the audit and
     compensation committees; and

  .  all of the parties to the shareholder agreement have agreed to vote the
     shares of common stock owned by them in favor of each other's nominees.

The rights of each person mentioned above will terminate when such person no
longer owns at least ten percent of our common stock.

   The parties to the stock purchase agreement and Mr. Skelsey entered into an
amended and restated registration rights agreement dated July  , 1999, which
provides, among other things:

  .  the TTC Investors Group has the right to require the filing of one
     registration statement with the SEC during any 12 month period to
     register for sale shares of our common stock owned by it;

  .  holders of a majority of the shares of our common stock held by
     Tanning's founders and Mr. Skelsey have the right to require the filing
     of a short-form registration statement with the SEC during any 12 month
     period to register for sale shares of our common stock owned by them;

  .  Tanning has the right to participate in any of the registrations
     described above and sell shares of its common stock under such
     registration to the extent of   % of the shares to be sold in the
     offering; and

  .  all parties to the registration rights agreement have rights to
     participate in registration statements filed by Tanning for the sale of
     common stock in an underwritten offering for its own account, subject to
     the ability of the underwriters to limit the number of shares included
     in the registration and giving priority to issuances by Tanning.

   The existence and exercise of these registration rights may make it more
difficult for us to arrange future financing and may have an adverse effect on
the market price of our common stock.

Transactions with Directors and Officers

   On September 1, 1998, Mr. Skelsey, a Director, joined Tanning as Executive
Vice President and Chief Financial Officer. In connection with his employment,
we granted Mr. Skelsey options to purchase 1,628,760 shares of our common stock
at an exercise price of $3.82. Options to purchase 407,190 shares were
immediately exercisable and the remaining options will vest over the next three
years. Mr. Skelsey exercised 261,911 of these options in February 1999.

   Upon completion of this offering, we will lend on a recourse basis to each
of Larry G. Tanning and Bipin Agarwal $250,000. These loans were entered into
in connection with a significant reduction in the compensation of Messrs.
Tanning and Agarwal pursuant to their revised employment agreements. The loans
will bear interest at the lowest rate permitted by the IRS to avoid the
imputation of interest income. The principal and all accrued interest on the
loans will be repayable after two years.

                                       52
<PAGE>


   In 1996 and 1997, we repaid approximately $490,000 of remaining principal on
notes evidencing financing arrangements entered into in 1995 with Hippeli
Enterprises, Inc., Toni S. Hippeli Unitrust and V. Jerome Nickerson Unitrust.
Toni S. Hippeli, one of our directors and the managing member of our
predecessor, owns 50% of the capital stock of Hippeli Enterprises, Inc. and V.
Jerome Nickerson, Ms. Hippeli's husband, owns the remaining 50%. Hippeli
Enterprises, Inc. is a significant stockholder of Tanning. Ms. Hippeli and Mr.
Nickerson are co-trustees of both Toni S. Hippeli Unitrust and V. Jerome
Nickerson Unitrust.

   In connection with an agreement entered into between our company and Mr.
Nickerson as of January 1997, Mr. Nickerson received a commission on the sale
of a software product by one of our subsidiaries in the amount of approximately
$100,000, of which approximately $85,000 has been paid, and $15,000 of which
will be paid between now and September 1, 2000. In addition, Mr. Nickerson also
received approximately $18,000 in wage compensation in 1998.

   We have employed Adesh Gupta, a brother-in-law of Bipin Agarwal, as a
Practice Leader since January, 1997 and as a Consultant from October, 1994
until January, 1997. Mr. Agarwal is one of our directors and our Senior Vice
President of Consulting Operations--North America, and also controls WinSoft
Corporation, which is a significant stockholder of Tanning. In 1998, Mr. Gupta
received approximately $245,000 in compensation.

   On April 7, 1997, we granted Mr. Gupta an option to acquire 327,389 shares
of our common stock at a per share purchase price of $2.90 per share. Of these
options, 245,542 vested upon the grant, 16,369 vested on April 7, 1998, 32,739
vested on April 7, 1999 and the remaining 32,739 will vest on April 7, 2000. On
June 9, 1998, we granted Mr. Gupta an additional option to acquire 65,478
shares of our common stock at a per share purchase price of $3.82 per share.
One-fourth of the shares subject to this option vested on June 9, 1999, and the
remaining three-fourths will vest in equal installments on each of June 9,
2000, 2001 and 2002.

   Mark W. Tanning, brother of Larry G. Tanning, has served as our Vice
President--Human Resources and Administration since January 1997. Larry Tanning
is our Chairman of the Board, President and Chief Executive Officer, and also
controls Courtney Rose Corporation, which is a significant holder of our stock.
In 1998, Mark Tanning received $212,280 in compensation. In addition, we have
entered into an employment agreement with Mark Tanning dated February 1, 1999.
Pursuant to the agreement, Mr. Tanning receives an annual salary of $180,000,
and for fiscal 1999 is eligible to receive a bonus of between 16% to 87% of his
annual salary upon attainment of performance goals, which is based upon the
attainment of performance targets involving the following: (1) global revenue,
(2) global earnings (before deductions for interest and taxes), and (3)
management and organizational objectives.

   Under the employment agreement, Mr. Tanning was granted an option to acquire
91,667 shares of our common stock at a per share purchase price of $3.82, which
vests (up to a maximum of 19,643 shares in 1999, 32,738 shares in 2000, and
39,286 shares in 2001) based upon Mr. Tanning's attainment of the performance
goals on which his cash bonus is based. Whether or not vested based on the
attainment of performance goals, all of the performance-based options will
become exercisable based on continued employment on December 1, 2003. The
employment agreement also contains customary non-competition, non-solicitation,
and non-disclosure covenants. Mr. Tanning was also granted an option to
purchase 49,107 shares of our common stock at a purchase price of $2.90 per
share. One-fourth of the shares subject to the option vested on each of June 1,
1997, February 1, 1998, and February 1, 1999. The remaining one-fourth is
scheduled to vest on February 1, 2000.

                             PRINCIPAL STOCKHOLDERS

   The following table presents information regarding the beneficial ownership
of our common stock as of June 25, 1999 and as adjusted to reflect the sale of
our common stock offered hereby by (1) each person (or group within the meaning
of Section 13(d)(3) of the Exchange Act) known by us to own beneficially 5% or
more of our common stock, (2) our directors and Named Executive Officers and
(3) all of our directors and executive officers as a group.

   As used in this table, "beneficial ownership" means the sole or shared power
to vote or direct the voting or to dispose or direct the disposition of any
security. A person is deemed to be the beneficial owner of securities that can
be acquired within 60 days from the date of this prospectus through the
exercise of any option, warrant or right. Shares of common stock subject to
options, warrants or rights that are currently exercisable or exercisable
within 60 days are deemed outstanding for computing the ownership percentage of
the person holding such options, warrants or rights, but are not deemed
outstanding for computing the ownership percentage of any other person. The
amounts and percentages are based upon 15,606,002 shares of common stock
outstanding as of June 25, 1999, and 19,606,202 shares of common stock
outstanding as of the completion of this offering, respectively.

   In the table below, unless otherwise noted, the address of our significant
stockholders is c/o our company.

                          DESCRIPTION OF CAPITAL STOCK

   We intend to amend our certificate of incorporation and bylaws prior to the
completion of this offering. The forms of our certificate of incorporation and
bylaws will be filed as exhibits to the registration statement of which this
prospectus is a part. The following summarizes the terms and provisions of our
capital stock upon the closing of this offering. The summary is not complete,
and you should read the forms of our certificate of incorporation and bylaws.

   Upon the closing of this offering, our authorized capital stock will consist
of 50 million shares, $0.01 par value per share, of common stock and 5 million
shares, par value $0.01 per share, of preferred stock.

Common stock

   Each share of our common stock will be identical in all respects and will
entitle its holder to the same rights and privileges enjoyed by all other
holders of shares of common stock and will subject them to the same
qualifications, limitations and restrictions to which all other holders of
common stock will be subject.

 Voting rights

   Holders of our common stock will be entitled to one vote per share on all
matters to be voted on by our stockholders. Holders of common stock will not
have cumulative rights, so that holders of a plurality of the shares of common
stock present at a meeting at which a quorum is present will be able to elect
all of our directors eligible for election in a given year. The holders of a
majority of the voting power of the issued and outstanding common stock will
constitute a quorum.

 Dividends

   Holders of our common stock will be entitled to receive ratably such
dividends, if any, as are declared by our board of directors out of funds
legally available for the declaration of dividends, subject to the preferential
rights of any holder of preferred stock that may from time to time be
outstanding.

 Liquidation

   Upon our liquidation, dissolution or winding up, the holders of our common
stock will be entitled to share pro rata in the distribution of all of our
assets available for distribution after satisfaction of all of our liabilities
and the payment of the liquidation preference of any preferred stock that may
be outstanding.

 Other provisions

   The holders of our common stock will have no preemptive or other
subscription rights to purchase common stock, and there will be no redemptive
rights or sinking fund provisions.

Preferred stock

   Our board of directors will be authorized to issue preferred stock in one or
more series and to establish the number of shares to be included in each series
and to fix the designations, powers, preferences and rights of the shares of
each series and any qualifications, limitations or restrictions of each series.
Because the board of directors will have the power to establish the preferences
and rights of the shares of any series of preferred stock, it may afford the
holders of any series of preferred stock preferences, powers and rights,
including voting rights, senior to the rights of the holders of common stock.
The issuance of preferred stock may have the effect of delaying, deferring or
preventing a change in control of Tanning.


                                       56
<PAGE>

Limitation on directors' liabilities

   Our certificate of incorporation will limit the liability of our directors
to us and our stockholders to the fullest extent permitted by Delaware law.
Specifically, our directors will not be personally liable for money damages for
breach of fiduciary duty as a director, except for liability

  .  for any breach of the director's duty of loyalty to us or our
     stockholders;

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

  .  under Section 174 of the Delaware General Corporation Law, which
     concerns unlawful payments of dividends, stock purchases or redemptions;
     and

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

Anti-takeover effects of our certificate of incorporation and bylaws and
provisions of Delaware law

   Our certificate of incorporation, bylaws and Section 203 of the Delaware
General Corporation Law contain provisions that may make the acquisition of
control of Tanning by means of a tender offer, open market purchase, proxy
fight or otherwise, more difficult.

 Section 203 of the Delaware General Corporation Law

   We must comply with the provisions of Section 203 of the Delaware General
Corporation Law. In general, Section 203 prohibits a publicly held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless the business
combination is approved in a prescribed manner.

   A "business combination" includes a merger, asset sale or other transaction
resulting in a financial benefit to the interested stockholder. An "interested
stockholder" is a person who, together with affiliates and associates, owns,
or, in some cases, within three years prior, did own, 15% or more of the
corporation's voting stock. Under Section 203, a business combination between
Tanning and an interested stockholder is prohibited unless it satisfies one of
the following three conditions:

  .  our board of directors must have previously approved either the business
     combination or the transaction that resulted in the stockholder becoming
     an interested stockholder;

  .  upon consummation of the transaction that resulted in the stockholder
     becoming an interested stockholder, the interested stockholder owned at
     least 85% of our voting stock outstanding at the time the transaction
     commenced, excluding, for purposes of determining the number of shares
     outstanding, shares owned by (1) persons who are directors and also
     officers and (2) employee stock plans, in some instances; and

  .  the business combination is approved by our board of directors and
     authorized at an annual or special meeting of the stockholders by the
     affirmative vote of the holders of at least 66 2/3% of the outstanding
     voting stock that is not owned by the interested stockholder.

 Staggered board

   Our certificate of incorporation will provide that the number of directors
shall be fixed from time to time by a resolution of our board of directors. Our
certificate of incorporation will also provide that the board of directors
shall be divided into three classes. The members of each class of directors
will serve for staggered three-year terms. As permitted by the Delaware General
Corporation Law, the members of our classified board of directors will only be
removable from office by our stockholders for cause. Vacancies on the board of
directors shall be filled by a majority of the remaining directors, or by a
sole remaining director, or by our stockholders if the vacancy was caused by
the action of our stockholders.

                                       57
<PAGE>

 Advance notice provision

   Our certificate of incorporation and bylaws will provide that stockholders
must follow an advance notification procedure to nominate candidates for the
board of directors and to propose business to be conducted at an annual
meeting.

 Special meetings of stockholders; written consent provision

   Our certificate of incorporation will provide that special meetings of our
stockholders may be called only by the board of directors, the chairman of the
board or the president. Our certificate of incorporation will also remove our
stockholders' ability to act by written consent. These provisions may render it
more difficult for stockholders to take action opposed by the board of
directors.

 Adoption, amendment or repeal of bylaws

   Our certificate of incorporation will limit the ability of our stockholders
to adopt, amend or repeal our bylaws. Specifically, any adoption, amendment or
repeal of a bylaw by our stockholders will require passage by a supermajority
vote.

 Supermajority approvals

   The provisions of our certificate of incorporation referred to above will
not be able to be altered without supermajority approval by our stockholders.

Transfer agent and registrar

   The Transfer Agent and Registrar for our common stock is ChaseMellon
Shareholder Services.

                                       58

                        SHARES ELIGIBLE FOR FUTURE SALE

   Upon completion of this offering, 19,606,002 shares of common stock will be
outstanding or 20,206,002 shares if the underwriters exercise their over-
allotment option in full. Of these shares, the 4,600,000 shares of common
stock, assuming the underwriters exercise their over-allotment option in full,
sold in this offering will be freely tradable without restriction or further
registration under the Securities Act, unless held by an "affiliate" of Tanning
as that term is defined in Rule 144 under the Securities Act. All of the shares
of common stock outstanding prior to this offering are "restricted securities,"
as such term is defined under Rule 144. These shares are restricted securities
because they were issued in private transactions not involving a public
offering and may not be sold in the absence of registration other than in
accordance with Rule 144 or Rule 701 under the Securities Act or another
exemption from registration. This prospectus may not be used in connection with
any resale of shares of common stock acquired in this offering by Tanning
Affiliates.

   We, our officers and directors and our existing stockholders have agreed not
to offer, sell, contract to sell, announce their intention to sell, pledge or
otherwise dispose of, directly or indirectly, or file with the SEC a
registration statement under the Securities Act relating to, any additional
shares of our common stock or securities convertible into or exchangeable or
exercisable for any shares of our common stock without the prior written
consent of Credit Suisse First Boston Corporation for a period of 180 days
after the date of this prospectus, except in our case for grants of employee
stock options pursuant to the terms of any stock option plans in effect on the
date of this prospectus, issuances of securities pursuant to the exercise of
employee stock options outstanding on the date of this prospectus, employee
stock purchases pursuant to the terms of a plan in effect on the date of this
prospectus or the issuance of shares pursuant to the exercise of any other
stock options outstanding on the date of this prospectus.

   In general, under Rule 144 as currently in effect, if a minimum of one year
has elapsed since the later of the date of acquisition of the restricted
securities from the issuer or from an affiliate of the issuer, a person (or
persons whose shares of common stock are aggregated), including persons who may
be deemed Tanning Affiliates, would be entitled to sell within any three-month
period a number of shares of common stock that does not exceed the greater of

  (1) one percent of the then-outstanding shares of common stock, which
      equals approximately 1,960,600 shares immediately after this offering,
      and

  (2) the average weekly trading volume during the four calendar weeks
      preceding the date on which notice of the sale is filed with the SEC.

   Sales under Rule 144 are also subject to certain restrictions as to the
manner of sale, notice requirements and the availability of current public
information about us. In addition, under Rule 144(k), if a period of at least
two years has elapsed since the later of the date restricted securities were
acquired from us or the date they were acquired from a Tanning Affiliate, a
stockholder who is not a Tanning Affiliate at the time of sale and who has not
been a Tanning Affiliate for at least three months prior to the sale would be
entitled to sell shares of common stock in the public market immediately
without compliance with the foregoing requirements under Rule 144. Rule 144
does not require the same person to have held the securities for the applicable
periods. The foregoing summary of Rule 144 is not intended to be a complete
description.

   In addition, any employee, director or officer of, or consultant to Tanning
who acquired shares pursuant to a written compensatory plan or contract may be
entitled to rely on the resale provisions of Rule 701, which permits non-
affiliates to sell their Rule 701 shares without having to comply with the
public information, holding period, volume limitation or notice provisions of
Rule 144, and permits Tanning Affiliates to sell their Rule 701 shares without
having to comply with the holding period restrictions of Rule 144, in each
case, commencing 90 days after the date of this prospectus.

   Immediately following this offering, none of the 15,606,002 "restricted
securities" will be available for immediate sale in the public market pursuant
to Rule 144(k). Beginning 90 days after the date of this prospectus, and
without consideration of the contractual restrictions described above,
shares acquired

                                       59
<PAGE>


upon exercise of options issued under our stock option plans and purchases
under our employee stock purchase plans will be outstanding and eligible for
sale in reliance upon Rule 701. Additional shares may be available if options
are exercised in the 180-day period following the date of this prospectus.
Shares of our common stock issued in reliance on Rule 701 may be resold by
holders who are not Tanning Affiliates under Rule 144 without compliance with
the holding period, amount and notice limitations and by holders who are
Tanning Affiliates under Rule 144 without compliance with the holding period
limitation. Following this offering, we intend to file a registration statement
on Form S-8 under the Securities Act to register    shares of common stock
reserved or to be available for issuance pursuant to our stock option plans.
Shares of common stock acquired upon exercise of options issued under our stock
option plans generally will be available for sale in the open market by holders
who are not Tanning Affiliates and, subject to the volume and other applicable
limitations of Rule 144, by holders who are Tanning Affiliates, unless such
shares are subject to the contractual restrictions described above.
Simultaneously with the effectiveness of this offering, we intend to file a
registration statement on Form S-8 under the Securities Act to register shares
of our common stock reserved for issuance under our employee stock purchase
plan. Shares of our common stock issued under our employee stock purchase plan
generally will be available for sale in the open market by holders who are not
Tanning Affiliates and, subject to the volume and other applicable limitations
of Rule 144, by holders who are Tanning Affiliates, unless such shares are
subject to the contractual restrictions described above.

   Tanning, Tanning's founders, the TTC Investors Group and Mr. Skelsey are
parties to an amended and restated registration rights agreement dated July  ,
1999, which provides the parties with the right to register the sale of shares
owned by them. These rights cover a significant amount of the shares of our
common stock and will also cover any shares obtained by parties to the
registration rights agreement. Registration of these shares of our common stock
would permit the sale of these shares without regard to the restrictions of
Rule 144. For a further discussion of these registration rights, see "Certain
Transactions--Stock Purchase Agreement, Shareholder Agreement and Registration
Rights Agreement."

   Prior to this offering, there has been no public market for our common
stock. No information is currently available and we cannot predict the timing
or amount of future sales of shares, or the effect, if any, that future sales
of shares, or the availability of shares for future sale, will have on the
market price of our common stock prevailing from time to time. Sales of
substantial amounts of our common stock (including shares issuable upon the
exercise of stock options) in the public market after the lapse of the
restrictions described above, or the perception that such sales may occur,
could materially adversely affect the prevailing market prices for our common
stock and our ability to raise equity capital in the future. See "Risk
Factors--Risks Related to this Offering--The sale or availability for sale of
substantial amounts of our common stock could adversely affect its market
price."

          UNITED STATES TAX CONSEQUENCES TO NON-UNITED STATES HOLDERS

   The following is a general discussion of the principal U.S. federal income
and estate tax consequences of the ownership and disposition of our common
stock by a Non-U.S. Holder. As used in this prospectus, the term "Non-U.S.
Holder" is a person other than:

  .  a citizen or individual resident of the United States,

  .  a corporation or partnership created or organized in or under the laws
     of the United States or of any political subdivision of the United
     States, other than a partnership treated as foreign under U.S. Treasury
     regulations,

  .  an estate whose income is includible in gross income for U.S. federal
     income tax purposes regardless of its source, or

  .  a trust, in general, if it is subject to the primary supervision of a
     court within the United States and the control of one or more U.S.
     persons.

   An individual may, subject to certain exceptions, be treated as a resident
of the United States for U.S. federal income tax purposes, instead of a
nonresident, by, among other things, being present in the United States for at
least 31 days in the calendar year and for an aggregate of at least 183 days
during a three-year period ending in the current calendar year--counting for
these purposes all of the days present in the current year, one-third of the
days present in the immediately preceding year and one-sixth of the days
present in the second preceding year. Residents are subject to U.S. federal tax
as if they were U.S. citizens.

   This discussion does not consider:

  .  U.S. state and local or non-U.S. tax consequences,

  .  specific facts and circumstances that may be relevant to a particular
     Non-U.S. Holder's tax position, including, if the Non-U.S. Holder is a
     partnership, that the U.S. tax consequences of holding and disposing of
     our common stock may be affected by certain determinations made at the
     partner level,

  .  the tax consequences for the shareholders, partners or beneficiaries of
     a Non-U.S. Holder,

  .  special tax rules that may apply to certain Non-U.S. Holders, including
     without limitation, banks, insurance companies, dealers in securities
     and traders in securities, or

  .  special tax rules that may apply to a Non-U.S. Holder that holds our
     common stock as part of a "straddle," "hedge" or "conversion
     transaction."

   The following discussion is based on provisions of the U.S. Internal Revenue
Code of 1986, applicable Treasury regulations, and administrative and judicial
interpretations, all as of the date of this prospectus, and all of which may
change, retroactively or prospectively. The following summary is for general
information. Accordingly, each Non-U.S. Holder should consult a tax advisor
regarding the U.S. federal, state, local and non-U.S. income and other tax
consequences of acquiring, holding and disposing of shares of our common stock.

Dividends

   We do not anticipate paying cash dividends on our common stock in the
foreseeable future. See "Dividend Policy." In the event, however, that
dividends are paid on shares of common stock, dividends paid to a Non-U.S.
Holder of common stock generally will be subject to withholding of U.S. federal
income tax at a 30% rate, or such lower rate as may be provided by an
applicable income tax treaty. Non-U.S. Holders should consult their tax
advisors regarding their entitlement to benefits under a relevant income tax
treaty.

                                       61

   Dividends that are effectively connected with a Non-U.S. Holder's conduct of
a trade or business in the United States or, if an income tax treaty applies,
attributable to a permanent establishment, or in the case of an individual, a
"fixed base," in the United States, as provided in that treaty ("U.S. trade or
business income"), are generally subject to U.S. federal income tax on a net
income basis at regular graduated rates, but are not generally subject to the
30% withholding tax if the Non-U.S. Holder files the appropriate U.S. Internal
Revenue Service form with the payor. Any U.S. trade or business income received
by a Non-U.S. Holder that is a corporation may also, under certain
circumstances, be subject to an additional "branch profits tax" at a 30% rate
or such lower rate as specified by an applicable income tax treaty.

   Dividends paid prior to 2001 to an address in a foreign country are
presumed, absent actual knowledge to the contrary, to be paid to a resident of
such country for purposes of the withholding discussed above and for purposes
of determining the applicability of a tax treaty rate. For dividends paid after
2000:

  .  a Non-U.S. Holder of common stock who claims the benefit of an
     applicable income tax treaty rate generally will be required to satisfy
     applicable certification and other requirements;

  .  in the case of common stock held by a foreign partnership, the
     certification requirement will generally be applied to the partners of
     the partnership and the partnership will be required to provide certain
     information, including a U.S. taxpayer identification number; and

  .  look-through rules will apply for tiered partnerships.

   A Non-U.S. Holder of common stock that is eligible for a reduced rate of
U.S. withholding tax under an income tax treaty may obtain a refund or credit
of any excess amounts withheld by filing an appropriate claim for a refund with
the IRS.

Gain on disposition of common stock

   A Non-U.S. Holder generally will not be subject to U.S. federal income tax
in respect of gain recognized on a disposition of common stock unless:

  .  the gain is U.S. trade or business income, in which case, the branch
     profits tax described above may also apply to a corporate Non-U.S.
     Holder;

  .  the Non-U.S. Holder is an individual who holds the common stock as a
     capital asset within the meaning of Section 1221 of the Internal Revenue
     Code, is present in the United States for more than 182 days in the
     taxable year of the disposition and meets certain other requirements;

  .  the Non-U.S. Holder is subject to tax pursuant to the provisions of the
     U.S. tax law applicable to certain U.S. expatriates; or

  .  we are or have been a "U.S. real property holding corporation" for
     federal income tax purposes at any time during the shorter of the five-
     year period ending on the date of disposition or the period that the
     Non-U.S. Holder held our common stock.

   Generally, a corporation is a "U.S. real property holding corporation" if
the fair market value of its "U.S. real property interests" equals or exceeds
50% of the sum of the fair market value of its worldwide real property
interests plus its other assets used or held for use in a trade or business.
Tanning believes that it has not been, is not currently, and does not
anticipate becoming, a "U.S. real property holding corporation" for U.S.
federal income tax purposes. The tax relating to stock in a "U.S. real property
holding corporation" will not apply to a Non-U.S. Holder whose holdings, direct
and indirect, at all times during the applicable period, constituted 5% or less
of the common stock, provided that the common stock was regularly traded on an
established securities market.

Federal estate tax

   Common stock owned or treated as owned by an individual who is a Non-U.S.
Holder at the time of death will be included in the individual's gross estate
for U.S. federal estate tax purposes, unless an applicable estate tax or other
treaty provides otherwise and, therefore, may be subject to U.S. federal estate
tax.

                                       62
<PAGE>

Information reporting and backup withholding tax

   We must report annually to the IRS and to each Non-U.S. Holder the amount of
dividends paid to that holder and the tax withheld with respect to those
dividends. Copies of the information returns reporting those dividends and
withholding may also be made available to the tax authorities in the country in
which the Non-U.S. Holder is a resident under the provisions of an applicable
income tax treaty or agreement.

   Under certain circumstances, U.S. Treasury Regulations require information
reporting and backup withholding at a rate of 31% on certain payments on common
stock. Under currently applicable law, Non-U.S. Holders of common stock
generally will be exempt from these information reporting requirements and from
backup withholding on dividends paid prior to 2001 to an address outside the
United States. For dividends paid after 2000, however, a Non-U.S. Holder of
common stock that fails to certify its Non-U.S. Holder status in accordance
with applicable U.S. Treasury Regulations may be subject to backup withholding
at a rate of 31% on payments of dividends.

   The payment of the proceeds of the disposition of common stock by a holder
to or through the U.S. office of a broker or through a non-U.S. branch of a
U.S. broker generally will be subject to information reporting and backup
withholding at a rate of 31% unless the holder either certifies its status as a
Non-U.S. Holder under penalties of perjury or otherwise establishes an
exemption. The payment of the proceeds of the disposition by a Non-U.S. Holder
of common stock to or through a non-U.S. office of a non-U.S. broker will not
be subject to backup withholding or information reporting unless the non-U.S.
broker is a "U.S. related person." In the case of the payment of proceeds from
the disposition of common stock by or through a non-U.S. office of a broker
that is a U.S. person or a "U.S. related person," information reporting, but
currently not backup withholding, on the payment applies unless the broker
receives a statement from the owner, signed under penalty of perjury,
certifying its non-U.S. status or the broker has documentary evidence in its
files that the holder is a Non-U.S. Holder and the broker has no actual
knowledge to the contrary. For this purpose, a "U.S. related person" is:

  .  a "controlled foreign corporation" for U.S. federal income tax purposes;

  .  a foreign person 50% or more of whose gross income from all sources for
     the three-year period ending with the close of its taxable year
     preceding the payment, or for such part of the period that the broker
     has been in existence, is derived from activities that are effectively
     connected with the conduct of a U.S. trade or business; or

  .  effective after 2000, a foreign partnership if, at any time during the
     taxable year, (A) at least 50% of the capital or profits interest in the
     partnership is owned by U.S. persons, or (B) the partnership is engaged
     in a U.S. trade or business.

   Effective after 2000, backup withholding may apply to the payment of
disposition proceeds by or through a non-U.S. office of a broker that is a U.S.
person or a "U.S. related person" unless certain certification requirements are
satisfied or an exemption is otherwise established and the broker has no actual
knowledge that the holder is a U.S. person. Non-U.S. Holders should consult
their own tax advisors regarding the application of the information reporting
and backup withholding rules to them, including changes to these rules that
will become effective after 2000.

   Any amounts withheld under the backup withholding rules from a payment to a
Non-U.S. Holder will be refunded, or credited against the holder's U.S. federal
income tax liability, if any, provided that the required information is
furnished to the IRS.

numbers of shares of common stock:

</TABLE>

   The underwriting agreement provides that the underwriters are obligated to
purchase all the shares of common stock in this offering if any are purchased,
other than those shares covered by the over-allotment option described below.
The underwriting agreement also provides that if an underwriter defaults, the
purchase commitments of non-defaulting underwriters may be increased or this
offering of common stock may be terminated.

   We have granted to the underwriters a 30-day option to purchase on a pro
rata basis up to 600,000 additional shares of common stock at the initial
public offering price less the underwriting discounts and commissions. This
option may be exercised only to cover any over-allotments of common stock.

   The underwriters propose to offer the shares of common stock initially at
the public offering price on the cover page of this prospectus and to selling
group members at that price less a concession of $    per share. The
underwriters and the selling group members may allow a discount of $    per
share on sales to other broker/dealers. After the initial public offering, the
public offering price and concession and discount to dealers may be changed by
the representatives.

   The following table summarizes the discounts and commissions and estimated
expenses that we will pay.

   The underwriters have informed us that they do not expect sales to accounts
over which they exercise discretionary authority to exceed 5% of the common
stock being offered.

   We, our officers and directors and our existing stockholders have agreed
not to offer, sell, contract to sell, announce their intention to sell, pledge
or otherwise dispose of, directly or indirectly, or file with the SEC a
registration statement under the Securities Act relating to, any additional
shares of our common stock or securities convertible into to exchangeable or
exercisable for any shares of our common stock without the prior written
consent of Credit Suisse First Boston Corporation for a period of 180 days

prospectus, except in our case for grants of employee stock options pursuant to
the terms of any plan in effect on the date of this prospectus, issuances of
securities pursuant to the exercise of employee stock options outstanding on
the date of this prospectus, employee stock purchases pursuant to the terms of
a plan in effect on the date of this prospectus or the issuance of shares
pursuant to the exercise of any other stock options outstanding on the date of
this prospectus.

   The underwriters have reserved for sale, at the initial public offering
price, up to 200,000 shares of common stock for employees and certain other
persons associated with Tanning who have expressed an interest in purchasing
common stock in this offering. The number of shares available for sale to the
general public in this offering will be reduced to the extent these persons
purchase the reserved shares. Any reserved shares not so purchased will be
offered by the underwriters to the general public on the same terms as the
other shares.

   We have agreed to indemnify the underwriters against liabilities under the
Securities Act or contribute to payments which the underwriters may be required
to make in that respect.

   We have applied to list the shares of common stock on The Nasdaq National
Market under the symbol "TANN."

   Prior to this offering, there has been no public market for the common
stock. The initial public offering price will be determined by negotiation
between us and the representatives, and does not reflect the market price for
the common stock following the offering. Among the principal factors considered
in determining the initial public offering price will be:

  .  the information in this prospectus and otherwise available to the
     representatives;

  .  market conditions for initial public offerings;

  .  the history of and prospects for the industry in which we will compete;

  .  our past and present operations;

  .  our past and present earnings and current financial position;

  .  the ability of our management;

  .  our prospects for future earnings;

  .  the present state of our development and our current financial
     condition;

  .  the recent market prices of, and the demand for, publicly traded common
     stock of generally comparable companies;

  .  the general condition of the securities markets at the time of this
     offering; and

  .  other relevant factors.

   We can offer no assurance that the initial public offering price will
correspond to the price at which the common stock will trade in the public
market subsequent to this offering or that an active trading market for the
common stock will develop and continue after this offering.

      The representatives may engage in over-allotment, stabilizing
transactions, syndicate covering transactions and penalty bids in accordance
with Regulation M under the Exchange Act.

  .  Over-allotment involves syndicate sales in excess of the offering size,
     which creates a syndicate short position. Stabilizing transactions
     permit bids to purchase the underlying security so long as the
     stabilizing bids do not exceed a specified maximum.

  .  Syndicate covering transactions involve purchases of the common stock in
     the open market after the distribution has been completed in order to
     cover syndicate short positions.


                                       65
<PAGE>

  .  Penalty bids permit the representatives to reclaim a selling concession
     from a syndicate member when the common stock originally sold by that
     syndicate member is purchased in a syndicate covering transaction to
     cover syndicate short positions.

   These stabilizing transactions, syndicate covering transactions and penalty
bids may cause the price of our common stock to be higher than it would
otherwise be in the absence of such transactions. These transactions may be
effected on The Nasdaq Stock Market's National Market or otherwise and, if
commenced, may be discontinued at any time.

                          NOTICE TO CANADIAN RESIDENTS

Resale restrictions

   The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of common stock are effected. Accordingly, any resale of the common
stock in Canada must be made in accordance with applicable securities laws
which will vary depending on the relevant jurisdiction, and which may require
resales to be made in accordance with available statutory exemptions or
pursuant to a discretionary exemption granted by the applicable Canadian
securities regulatory authority. Purchasers are advised to seek legal advice
prior to any resale of the common stock.

Representations of purchasers

   Each purchaser of common stock in Canada who receives a purchase
confirmation will be deemed to represent to Tanning and the dealer from whom
such purchase confirmation is received that: (1) such purchaser is entitled
under applicable provincial securities laws to purchase such common stock
without the benefit of a prospectus qualified under such securities laws, (2)
where required by law, that such purchaser is purchasing as principal and not
as agent, and (3) such purchaser has reviewed the text above under "Resale
restrictions."

Rights of action (Ontario purchasers)

   The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or rescission or rights of action under the civil liability provisions
of the U.S. federal securities laws.

Enforcement of legal rights

   All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be
possible for Canadian purchasers to effect service of process within Canada
upon the issuer or such persons. All or a substantial portion of the assets of
the issuer and such persons may be located outside of Canada and, as a result,
it may not be possible to satisfy a judgment against the issuer or such persons
in Canada or to enforce a judgment obtained in Canadian courts against such
issuer or persons outside of Canada.

Notice to British Columbia residents

   A purchaser of common stock to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
common stock acquired by such purchaser pursuant to this offering. Such report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR #95/17, a copy of which may be obtained from us. Only one such report
must be filed in respect of common stock acquired on the same date and under
the same prospectus exemption.

Taxation and eligibility for investment

   Canadian purchasers of common stock should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the common
stock in their particular circumstances and with respect to the eligibility of
the common stock for investment by the purchaser under relevant Canadian
legislation.

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors and Stockholders
 Tanning Technology Corporation

   We have audited the accompanying consolidated balance sheets of Tanning
Technology Corporation as of December 31, 1998 and 1997, and the related
consolidated statements of income, stockholders'/members' equity, and cash
flows for each of the three years in the period ended December 31, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Tanning
Technology Corporation at December 31, 1998 and 1997, and the consolidated
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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 (Information for the three months ended March 31, 1998 and 1999 is unaudited)

1.BUSINESS AND ORGANIZATION

   Tanning Technology Corporation (the "Company") is an information technology
services provider that architects, builds and deploys enterprise solutions for
corporations throughout the world. The Company specializes in large, complex,
integrated solutions that incorporate online transaction processing and very
large databases. Internet technologies are a central part of the Company's
solutions, enabling direct interaction among customers and business partners on
the World Wide Web and among employees within organizations on their private
intranets.

   Tanning Technology Group, LLC ("TTG") was formed under the laws of the state
of Colorado on February 8, 1995, as a result of the combination of Courtney
Rose Corporation, WinSoft Corporation, Strategic Technologies and Systems, and
Hippeli Enterprises. The assets and liabilities contributed by the members were
recorded at historical cost as reflected on the accounts of the respective
entities prior to the formation of TTG.

   On December 24, 1996, TTG entered into a Stock Purchase Agreement with AEA
Tanning Investors Inc. (AEA Tanning Investors Inc., together with certain
limited liability companies of which it is the managing member, the "TTC
Investors Group"). As a result of this agreement, on January 31, 1997 TTG
effected a series of transactions whereby TTG was merged into Tanning
Technology Corporation, a Delaware corporation newly formed in conjunction with
this transaction. The membership interests of the members of TTG were converted
into shares of Class A common stock of the Company. On the same date, the TTC
Investors Group purchased 3,657,342 shares of Class B common stock from the
Company for $9,076,910 and purchased directly from the former members of TTG
$3,648,090 of accounts receivable that had been distributed to the members of
TTG (see Note 7). On June 6, 1997, the TTC Investors Group purchased an
additional 1,469,917 shares of Class B common stock from the Company for
$3,648,090, which was comprised of $3,126,636 cash and accounts receivable with
a value of $521,454. On June 9, 1998, the TTC Investors Group purchased an
additional 569,511 shares of Class B common stock from the Company for
$1,900,000.

   The Company's wholly-owned direct subsidiaries include Nextek Software Corp.
and a United Kingdom subsidiary, Tanning Technology Europe Limited ("TTEL").
During 1998, the Company established a 51% owned Indian subsidiary, Tanning
Technology India Pvt Ltd ("TTI"). The operating results of TTI are not material
to the consolidated results of operations. Nextek Software Corporation sold the
rights to certain developed software during 1998 and has no current plans for
future product sales.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Consolidation

   The accompanying financial statements include the accounts of the Company
and all majority-owned subsidiaries. All significant intercompany transactions
have been eliminated.

Limited Liability Company ("LLC")

   An LLC is an unincorporated association of two or more persons, whose
members have limited personal liability for the obligations or debts of the
entity. For federal income tax purposes, the Company was classified as an LLC
through January 31, 1997, at which time the Company converted from an LLC to a
C Corporation.

                         TANNING TECHNOLOGY CORPORATION

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


Revenue Recognition

   Substantially all of the Company's contracts are billed on a time and
materials basis. Under time and materials contracts, the Company recognizes
revenue as services are provided. In addition, the Company is generally
reimbursed for reasonable expenses incurred under its contracts. The Company
recognizes revenue for fixed price contracts on a percentage of completion
basis. The Company recognizes revenue from its software sales in accordance
with the provisions of the American Institute of Certified Public Accountants'
Statement of Financial Position 97-2, Software Revenue Recognition, which
provides guidance on applying generally accepted accounting principles in
recognizing revenue on software transactions.

Cash and Cash Equivalents

   The Company considers all highly liquid investments (including money market
accounts) with a maturity of three months or less when purchased to be cash
equivalents.

Property and Equipment

   Property and equipment is stated at cost. Depreciation and amortization,
which includes amortization of assets under capital leases, is based on the
straight-line method over the following estimated useful lives:

<TABLE>

     Computer equipment.................................... 5 years
     Office furniture and equipment........................ 7 years
     Computer software..................................... 3 years
     Leasehold improvements................................ Lesser of the life
                                                            of the improvement
                                                            or the related asset
</TABLE>

Income Taxes

   The Company accounts for income taxes under the provisions of Statement of
Financial Accounting Standard ("SFAS") No. 109, Accounting for Income Taxes,
which requires that the Company account for income taxes using the liability
method. Under SFAS No. 109, deferred income taxes are provided for temporary
differences in recognizing certain income and expense items for financial
reporting and tax reporting purposes. Upon completion of the merger of TTG with
the Company (see Note 1), the LLC status was terminated and the Company began
providing for current and deferred income taxes as a C corporation.
Accordingly, the consolidated statement of income for the year ended December
31, 1997 includes a one-time credit (included in benefit from income taxes) of
approximately $70,000 to record the related deferred tax asset. Prior to the
conversion to a C corporation, no provision for income taxes was provided since
members included their distributive shares of revenue and deductions of the
limited liability company in their personal capacities, pursuant to election
under Subchapter K of the Internal Revenue Code.

Foreign Currency Translation

   The financial statements of TTEL are prepared in pound sterling and
translated into U.S. dollars based on the current exchange rate at the end of
the period for the balance sheet and a weighted-average rate for the period on
the statement of income. Translation adjustments are reflected as foreign
currency translation adjustments within comprehensive income in
stockholders'/members' equity and accordingly have no effect on net income.
Transaction adjustments for TTEL are included in income. Foreign currency
transaction adjustments are not material to income.

                         TANNING TECHNOLOGY CORPORATION

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


Fair Value of Financial Instruments

   The carrying amounts of the Company's cash and cash equivalents,
receivables, payables and accrued expenses approximate fair value due to the
short maturity of these instruments. The fair value of the Company's long-term
debt approximates carrying value and was estimated by discounting future cash
flows using rates currently available for debt with similar terms and remaining
maturities.

Sales to Significant Customers

   The Company provides services to a small number of customers. Two customers
accounted for 31% each of total revenues in 1996. Two customers accounted for
40% and 22%, respectively, of total revenues in 1997. Two customers accounted
for 28% and 11%, respectively, of total revenues in 1998. Four customers
accounted for 31%, 12%, 12% and 12%, respectively, of total revenues for the
first three months of 1999. The Company performs periodic credit evaluations of
its customers' financial condition and collateral generally is not required.
Overall credit losses are within management's expectations.

Accounting Estimates in the Preparation of Financial Statements

   The preparation of financial statements in conformity with generally
accepted accounting principles requires the Company's 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 revenues and expenses
during the reporting period. Actual results could differ from those estimates.

Stock-Based Compensation

   The Company has elected to follow Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees ("APB 25"), and related
interpretations in accounting for its employee stock options. Under APB 25,
because the exercise price of the Company's employee stock options equals the
market price of the underlying stock on the date of grant, no compensation
expense is recorded. The Company has adopted the disclosure-only provisions of
SFAS No. 123.

Earnings Per Share

   The Company has adopted the provisions of SFAS No. 128, Earnings Per Share.
SFAS 128 requires entities to present both basic earnings per share ("EPS") and
diluted EPS. Basic EPS excludes dilution and is computed by dividing income
(loss) available to common stockholders by the weighted-average number of
common shares outstanding for the period. Diluted EPS reflects the potential
dilution that could occur if securities or other contracts to issue common
stock were exercised or converted into common stock or resulted in the issuance
of common stock that then shared in the earnings of the entity. Potential
dilution of securities exercisable into common stock was computed using the
treasury stock method based on the average fair market value of the stock. EPS
for 1996 is not presented since there were no shares outstanding due to the
Company's status as an LLC. The following table reflects the basic and diluted
weighted average shares.

4.STOCKHOLDERS'/MEMBERS' EQUITY

   On May 17, 1999, the Company filed a registration statement with the
Securities and Exchange Commission for an initial public offering of shares of
its common stock. In connection with the planned initial public offering, the
Company intends to effect a 1 for 3.05 reverse stock split of its Class A and
Class C common shares; and a 1 for 2.67 reverse stock split of its Class B
common shares, and each share of Class A, Class B and Class C common stock will
be converted into one class of voting common stock. All references to common
shares in the accompanying financial statements reflect the Company's
anticipated reverse stock splits, but not the conversion to one class of common
stock, retroactively applied to all periods presented.

   On March 17, 1997, the Board of Directors declared a 21.053:1 stock split of
the Company's Class A and B common stock, effected in the form of a stock
dividend of 20.053 shares of Class A and B common stock for each one share
issued and outstanding. Class A and B common stock issued and additional paid-
in capital as of December 31, 1997 have been restated to reflect this split.
The number of shares issued at December 31, 1997, after giving effect to both
the purchases by the TTC Investors Group and the stock splits, was 9,520,293,
5,127,259 and 0 of Class A, B and C common stock, respectively.

   Effective April 30, 1998, the Board of Directors declared a 5:1 stock split
of the Company's Class A and B common stock, effected in the form of a stock
dividend of 4 shares of Class A and B common stock for each one share issued
and outstanding. The split was effected so that no change was made to the par
value of all

outstanding shares. In conjunction with the stock split, each outstanding stock
option granted under the Stock Option Plan was also increased while the
exercise price of each stock option was decreased by the corresponding 5:1
ratio.

   In July 1998, the number of authorized shares of Class C nonvoting common
stock was increased to 8,536,568. The number of shares issued at December 31,
1998, after giving effect to both the stock splits and the purchases by the TTC
Investors Group, was 9,520,293, 5,696,770 and 0 of Class A, B and C common
stock, respectively. As of March 31, 1999 there were 9,520,293, 5,696,770 and
281,555 shares issued and outstanding of Class A, B and C common stock,
respectively.

options for up to 5,247,474 shares of Class C nonvoting common stock. All
options granted under the 1998 Plan, once vested, are exercisable until July
24, 2008, at which time the 1998 Plan shall terminate.

   Pro forma information regarding net income is required by SFAS No. 123, and
has been determined as if the Company had accounted for its employee stock
options under the fair value method of that Statement. The fair value of these
options was estimated at the date of grant using a Black-Scholes option-pricing
model with the following weighted average assumptions for 1998 and 1997,
respectively: risk-free interest rates of 4.64%-5.36% and 5.77%; dividend
yields of 0; volatility factors of 0 and a weighted-average expected life of
the option of 5 years.

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

   For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting periods. The
Company's pro forma net income (loss) and earnings per share was as follows:

11.SEGMENT REPORTING

   During 1998, the Company adopted Statement of Financial Accounting Standards
No. 131, "Disclosures about Segments of an Enterprise and Related Information"
("SFAS 131"). SFAS 131 requires a business enterprise, based upon a management
approach, to disclose financial and descriptive information about its operating
segments. Operating segments are components of an enterprise about which
separate financial information is available and regularly evaluated by the
chief operating decision maker(s) of an enterprise. Under this definition, the
Company operated as a single segment for all years and periods presented.

   SFAS 131 also requires the disclosure of certain financial information
pertaining to geographic areas. Long-lived assets located outside of the United
States are not material. Information about the Company's revenues by geographic
area is as follows (in thousands):

12.EMPLOYEE STOCK PURCHASE PLAN

   In March 1999, the Company established the Tanning Technology Corporation
1999 Qualified Stock Purchase Plan (the "Plan"). The Company intends that the
Plan qualify as an employee stock purchase plan under Section 423 of the
Internal Revenue Code. Employees scheduled to work at least 20 hours per week
and who have completed at least three months of continuous full-time employment
in the service of the Company are eligible to participate in the Plan. Under
the Plan, eligible employees can purchase shares, subject to limitations, of
the Company's Class C nonvoting common stock at a discount not to exceed 15% of
the market price as defined. No purchases were made as of March 31, 1999. On
April 15, 1999, the Company issued 59,094 shares of Class C nonvoting common
stock in conjunction with this plan.

Item 14. Indemnification of Directors and Officers.

   Section 145 of the Delaware General Corporation Law (the "DGCL") provides
that a corporation may indemnify directors and officers as well as other
employees and individuals against expenses (including attorneys' fees),
judgments, fines, and amounts paid in settlement in connection with specified
actions, suits and proceedings, whether civil, criminal, administrative, or
investigative (other than action by or in the right of the corporation--a
"derivative action"), if they acted in good faith and in a manner they
reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe their conduct was unlawful. A similar standard is
applicable in the case of derivative actions, except that indemnification only
extends to expenses (including attorneys' fees) incurred in connection with the
defense or settlement of such action, and the statute requires court approval
before there can be any indemnification where the person seeking
indemnification has been found liable to the corporation. The statute provides
that it is not exclusive of other indemnification that may be granted by a
corporation's certificate of incorporation, bylaws, disinterested director
vote, stockholder vote, agreement, or otherwise.

   Tanning's bylaws currently, and Tanning's certificate of incorporation and
bylaws, as they will be amended and restated immediately prior to this
offering, require Tanning to indemnify to the fullest extent authorized by the
DGCL any person made or threatened to be made a party to an action, suit or
proceeding, whether criminal, civil, administrative or investigative, by reason
of the fact that he or she or a person of whom he or she is the legal
representative is or was a director of the officer of Tanning or is or was
serving at the request of Tanning as a director, officer, employee or agent of
another corporation or of a partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans maintained
or sponsored by Tanning. Tanning will also be able to grant indemnification to
its other employees or agents. The amended and restated certificate of
incorporation and bylaws will also require Tanning to advance expenses, as
incurred, to its directors, officers and other agents and employees in
connection with a legal proceeding, to the fullest extent permitted by the
DGCL, subject to certain limited exceptions. The amended and restated
certificate of incorporation and bylaws will also permit Tanning to enter into
indemnification agreements with its directors and officers and to obtain
director and officer liability insurance.

                                      II-1
<PAGE>

   As permitted by Section 102(b)(7) of the DGCL, Tanning's certificate of
incorporation eliminates the liability of a director to the corporation or its
stockholders for monetary damages for such breach of fiduciary duty as a
director, except for liabilities arising (a) from any breach of the director's
duty of loyalty to the corporation or its stockholders; (b) from acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of law; (c) under Section 174 of the DGCL; or (d) from any
transaction from which the director derived an improper personal benefit.

   Tanning has obtained primary and excess insurance policies insuring its
directors and officers and those of its subsidiaries against certain
liabilities they may incur in their capacity as directors and officers. Under
these policies, the insurer, on behalf of Tanning, may also pay amounts for
which Tanning has granted indemnification to the directors or officers.

   Additionally, reference is made to the Underwriting Agreement that will be
filed as Exhibit 1.1 to this registration statement, which provides for
indemnification by the Underwriters of Tanning, its directors and officers who
sign the registration statement and persons who control Tanning, under certain
circumstances.

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

   The undersigned registrant hereby undertakes that:

   (1) 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.

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

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

                   Report of Independent Auditors on Schedule

Board of Directors and Stockholders
 Tanning Technology Corporation

   We have audited the consolidated financial statements of Tanning Technology
Corporation as of December 31, 1998 and 1997, and for each of the three years
in the period ended December 31, 1998, and have issued our report thereon dated
February 26, 1999 (included elsewhere in this Registration Statement). Our
audits also included the financial statement schedule listed in Item 16(b) of
this Registration Statement. These schedules are the responsibility of the
Company's management. Our responsibility is to express an opinion based on our
audits.

   In our opinion, the financial statement schedule referred to above, when
considered in relation to the basic financial statements taken as a whole,
presents fairly in all material respects the information set forth therein.

Effect. New Tanning will be on the Closing Date duly qualified to do business
and in good standing as a foreign corporation in all jurisdictions where the
nature of the property owned or leased by it and by the Company, or the nature
of the business conducted by it or by the Company make such qualification
necessary, except where such lack of qualification would not have a Material
Adverse Effect. True and complete copies of the governing documents of the

by third parties ("Third Party Claims") or has any other claim for
                   -------------------
indemnification other than a Third Party Claim, which is to be the basis for a
claim for indemnification hereunder, the Indemnified Party shall give prompt
written notice thereof to the other party or parties (the "Indemnifying Party")
                                                           ------------------
reasonably indicating (to the extent known) the nature of such claims and the
basis thereof; provided, however, that failure of the Indemnified Party to give
the Indemnifying Party prompt notice as provided herein shall not relieve the
Indemnifying Party of any of its obligations hereunder unless and only to the
extent that the Indemnifying Party shall have been prejudiced thereby. Upon
notice from the Indemnified Party, the Indemnifying Party may, but shall not be
required to, assume the defense of any such Third Party Claims, including its
compromise or settlement, and the Indemnifying Party shall pay all reasonable
costs and expenses thereof and shall be fully responsible for the outcome
thereof; provided, however, that in such case, the Indemnifying Party shall have
         --------  -------
no obligation to pay any further costs or expenses of legal counsel of the
Indemnified Party thereafter incurred in connection with such defense. No
compromise or settlement in respect of any Third Party Claims may be effected by
the Indemnifying Party without the Indemnified Party's prior written consent
(which consent shall not be unreasonably withheld or delayed), unless the sole
relief is monetary damages that are paid in full by the Indemnifying Party (and
satisfactory releases are delivered to the Indemnified Party). The Indemnifying
Party shall give notice to the Indemnified Party as to its intention to assume
the defense of any such Third Party Claims within thirty (30) days after the
date of receipt of the Indemnified Party's notice in respect of such Third Party
Claims. If an Indemnifying Party does not, within thirty (30) days after the
Indemnified Party's notice is given, give notice to the Indemnified Party of its
assumption of the defense of the Third Party Claims, the Indemnifying Party
shall be deemed to have waived rights to control the defense thereof. If the
Indemnified Party assumes the defense of any Third Party Claims because of the
failure of the Indemnifying Party to do so in accordance with this Section 9.4,
it may do so in such reasonable manner as it may deem appropriate, and the
Indemnifying Party shall pay all reasonable costs and expenses of such defense.
The Indemnifying Party shall have no liability with respect to any compromise or
settlement thereof effected without its prior written consent (which consent
shall not be unreasonably withheld or delayed), unless the sole relief granted
was equitable relief for which the Company would have no liability or to which
the Company would not be subject.

                                     -24-
<PAGE>

          (b) Notwithstanding the foregoing, with respect to any Third Party
Claim that the Indemnifying Party is defending, the Indemnified Party shall have
the right to retain separate counsel to represent it and the Indemnifying Party
shall pay the fees and expenses of such separate counsel if there are conflicts
that make it reasonably necessary for separate counsel to represent the
Indemnified Party and the Indemnifying Party.

     Section 9.5  Limitations on Indemnification.  (a)  The provisions for
                  ------------------------------
indemnity under Sections 9.2(a) and 9.3(a), as the case may be, shall be
effective only when the aggregate amount of all Losses for which indemnification
is sought from the Original Members and the Principals, on the one hand, or AEA,
on the other, under Sections 9.2(a) or 9.3(a), respectively, exceeds $200,000,
in which case the Indemnified Party shall be entitled to indemnification for all
of the Indemnified Party's Losses in excess thereof.

          (b) In no event shall the Original Members and the Principals, on the
one hand, or AEA, on the other, be liable for an amount, in the aggregate,
greater than $6,500,000 for all claims made against it under Sections 9.2(a) or
9.3(a), as the case may be.

          (c) Notwithstanding the foregoing, Losses arising out of a breach of
Sections 3.13 or 3.17(b) or any intentional failure to perform any covenant or
agreement contained in this Agreement shall be indemnified without regard to
this Section 9.5.

     Section 9.6  Exclusive Remedy.  Except as expressly provided otherwise in
                  ----------------
this Agreement, following the Closing, the indemnification provisions set forth
in this Article IX shall be the sole and exclusive remedy of the parties hereto
for damages for breaches of representations and warranties and covenants and
other agreements.

                          2.  Principal Terms.
                              ---------------

     2.1  Governance.  Management decisions will be made by a majority of the
          ----------
          Board of Directors.  Board representation will be proportionate to
          ownership interest (i.e. AEA will have the right to appoint 1/3 of the
                              ----
          board members).  Notwithstanding the foregoing, the following actions
          would require the approval of a majority of the Board, including at
          least one AEA director:

          .  Acquisitions or dispositions of assets or operations outside the
             ordinary course; dissolution, liquidation, mergers or other
             extraordinary transactions.

          .  The issuance of private or public equity or public debt of New
             Tanning.

          .  The incurrence by New Tanning of significant indebtedness ($5
             million or more).

          .  Any related party transactions (including employment agreements
             with any 5% equity holders or affiliates of 5% equity holders).

          .  Any material change in management (including appointment or removal
             of senior management) or compensation arrangements.

          .  Amendments or modifications to New Tanning's governing documents or
             terms of securities or other interests.

          .  Any declaration of dividends or other distributions (including
             redemptions of stock).

          .  Other corporate actions of similar significance outside the
             ordinary course.

     2.2  Information.
          -----------


                                     -34-

          .  New Tanning will provide annual and monthly financial statements to
             AEA in a form satisfactory to AEA, together with annual budgets and
             operating plans (including balance sheets and statements of cash
             flows).

          .  New Tanning will provide AEA access to New Tanning's books and
             records.

          committee of the Board.

     2.4  Transfer.  No equity holder will be permitted to transfer (directly or
          --------
          indirectly) its interest in New Tanning without the approval of the
          holders of 80% of the voting shares (including the transferor) of the
          equity interests in New Tanning.  "Tag along" rights (which grant to
          all shareholders the right to participate, pro rata, in any transfer)
          and "drag along" rights (which provide that if shareholders holding
          80% of the shares choose to sell at least substantially all of the
          shares they own, they can require the other shareholders to sell the
          same percentage of their shares) would apply to any such approved
          sale.

     2.5  Registration Rights.
          -------------------

          .  AEA will have the right to one demand registration right in each 12
             month period beginning on the 24 month anniversary of the Closing.
             This right includes the right to require a primary IPO by New
             Tanning, as well as the right to demand registration of shares held
             by the AEA investor participants.

          .  AEA and the Original Members will have customary "piggy-back" and
             S-3 registration rights.

          .  Piggy-back and S-3 registration rights will be subject to standard
             marketability restrictions.

Technology Group, L.L.C., Courtney Rose Corporation, WinSoft Corporation,
Hippeli Enterprises Inc., Stephen Brobst, Larry Tanning, Bipin Agarwal, Toni
Hippeli and AEA Tanning Investors Inc. ("AEA").  Except as set forth herein, all
                                         ---
terms used but not defined herein shall have the meanings ascribed to them in
the Stock Purchase Agreement.

1.  Initial Purchase.
    ----------------

     Pursuant to Exhibit 4 of the Stock Purchase Agreement, on the terms and
conditions contained in the Stock Purchase Agreement, at the Closing, AEA
(and/or its designee) will pay to New Tanning $9,076,910, and New Tanning will
issue and sell to AEA (and/or its designee) 92,730.716 shares of Class B Common
Stock of New Tanning (the "Initial AEA Shares").
                           ------------------

2.  Subsequent Purchases.
    --------------------

     At or prior to the four month anniversary of the Closing Date, AEA (and/or
its designee) shall purchase from New Tanning and New Tanning shall issue and
sell to AEA (and/or its designee), on the terms and conditions contained in the
Stock Purchase Agreement, 37,269.284 shares of Class B Common Stock of New
Tanning (which constitute the AEA Shares which AEA did not purchase at the
Closing, and which, taken together with the Initial AEA Shares, shall, when
issued, equal 32% of the issued and outstanding shares of common stock of New
Tanning) (the "Remaining AEA Shares").  AEA shall have the right to purchase
               --------------------

    ------

     Pursuant to Section 5.2(b) of the Stock Purchase Agreement, except as
agreed to in writing by AEA, from the date of the Stock Purchase Agreement to
the Closing, the Company and each Subsidiary agreed, and the Tanning Parties
agreed to cause the Company and each of the Subsidiaries, not to, inter alia,
effect any settlement or resolution of matters relating to NexTek.  The Company
and each of the Tanning Parties hereby agree that such agreement shall survive
the Closing indefinitely.

               portions of any Additional Buildings that are occupied by tenants

               in which the Rentable Area used to calculate the Building
               Percentage changes, the Building Percentage shall be calculated
               based on the average of such Rentable Area during such Calendar
               Year, taking into account the date(s) on which the change occurs.
               The Building Percentage shall initially be that percentage set

               any additional real property located proximate thereto that may

               Land, the parking structure and other improvements in the Complex

               include ground rent and principal and interest payments on loans

               costs related solely to any Additional Buildings at the Complex;
               however, Operating Expenses shall include costs required to be
               capitalized for federal income tax purposes that are (i) incurred
               in order to conform to changes subsequent to the date of this

          (9)  "Premises" means that portion of the Building identified as such
               on Exhibit B and containing the Rentable Area set forth in
               Section 1A(7). The Premises do not include, and Landlord hereby

               all: janitor closets, stairways and stairwells; fan, mechanical,
               electrical, telephone and similar rooms (other than those

               assessments (general, special or otherwise) and license fees,
               levied or assessed by any federal, state, county or local
               government or by any other taxing district or authority upon or
               with respect to the Building, the maintenance equipment and
               vehicles, elevators, building machinery and other personal
               property owned or leased by Landlord and necessary for the
               operation of the Building, plus the Building Percentage of such
               real estate and personal property taxes and assessments upon or
               with respect to the Land, the parking structure and other
               improvements in the Complex and similar personal property
               necessary for the operation of the Complex. Notwithstanding the
               foregoing, Taxes shall not include taxes and assessments on the
               improvements included in any Additional Buildings or any personal
               property used solely in connection with any Additional Buildings.
               Should any governmental authority having jurisdiction over the
               Complex impose an income or franchise tax or a tax on rents in
               substitution, in whole or in part, for such real estate or
               personal property taxes or in lieu of any increase in such taxes,
               such income, franchise or rent tax shall be deemed to constitute
               Taxes

                                     - 3 -

               hereunder. Taxes shall include all special taxes and special
               assessments, installments of which are required to be paid during
               any Calendar Year, and all fees and costs, including attorneys'
               fees and expenses, incurred by Landlord in seeking to reduce, or
               limit the increase in, any Taxes, regardless of whether any
               reduction or limitation is obtained. All references to Taxes for
               a particular year shall be deemed to refer to Taxes levied,
               assessed or otherwise imposed for such year without regard to
               when such Taxes are payable.

          (12) "Tenant's Proportionate Share" means that percentage obtained
               from time to time by dividing the Rentable Area of the Premises
               by the Rentable Area of the Building. For any Calendar Year in
               which the Rentable Area used to calculate the Tenant's
               Proportionate Share changes, the Tenant's Proportionate Share
               shall be calculated based on the average of such Rentable Area
               during such Calendar Year, taking into account the date(s) on
               which the change occurs. The Tenant's Proportionate Share shall
               initially be that percentage set forth in Section 1A(8).
               Notwithstanding the foregoing provisions, during any portion of
               the Term that the Building is not fully occupied, the Tenant's
               Proportionate Share with respect to those Operating Expenses
               which are variable depending upon occupancy (such as janitorial
               costs) shall be equitably adjusted so as to attribute to Tenant
               its fair share of such variable Operating Expenses, but shall not
               be adjusted with respect to any Operating Expenses which are not
               variable depending upon occupancy (such as liability insurance
               and landscape maintenance). If Landlord should lease any premises
               in the Building on a net lease" or similar basis such that
               Landlord is not obligated to furnish to the tenant(s) of such
               premises any of the services described in Section 7, then, with
               respect to those items of Operating Expenses that would have been
               incurred by Landlord had Landlord been required to furnish all of
               the services described in Section 7 to such premises, such
               premises shall be deemed "unoccupied" for purposes of the
               preceding sentence depending upon occupancy (such as liability
               insurance and landscape maintenance).

          (13) "Term" means the term of this Lease which shall commence on the
               date set forth in Section 1A(1) or the later date to which such
               commencement may be extended pursuant to Section 5C (the
               "Commencement Date") and shall terminate on the date set forth in
               Section 1A(2) or the later date to which such termination may be
               extended pursuant to Section 5C (the "Termination Date"), unless
               terminated earlier or extended further as provided in this Lease.


     Certain additional defined terms are used in this Lease; such terms have
the meanings set forth in the sections of this Lease where the definitions of
such terms appear.

2.  DEMISE

     In consideration of the keeping, observance and performance by Tenant of
     the provisions, covenants and agreements contained in this Lease and the
     payment by Tenant of the rents herein reserved, Landlord hereby demises and
     leases to Tenant and Tenant hereby takes from Landlord, the Premises for
     the Term hereof, subject to the terms and conditions of this Lease and
     existing covenants, conditions, restrictions, easements and encumbrances
     affecting the same.

                                     - 4 -
<PAGE>

3.  BASE RENT

     Commencing on the Commencement Date and thereafter during the Term, Tenant
     covenants and agrees to pay the rent described in this Section 3 (the "Base
     Rent") in accordance with the provisions hereof. Base Rent during each
     Calendar Year shall be payable in monthly installments as set forth in
     Section 1A(2), in advance on or before the first day of each and every
     month during the Term. If the Term commences other than on the first day of
     a month or ends other than on the last day of a month, Base Rent for such
     month shall be prorated. Upon the execution hereof, Tenant shall pay the
     monthly installment for the first full month of the Term for which Base
     Rent is due. All payments of Base Rent and other "Rent" (as defined below)
     shall be made at such place as Landlord may from time to time designate to
     Tenant in writing, without any demand, set-off or deduction whatsoever.
     Notwithstanding anything to the contrary contained herein, Landlord hereby
     waives payment of Base Rent for the first two (2) months of the initial
     Term of this Lease.

4.  ADDITIONAL RENT

     In addition to paying the Base Rent specified in Section 3 hereof, Tenant
     shall pay as "Additional Rent" the amounts described in this Section 4. The
     Base Rent, the Additional Rent and all other amounts payable by Tenant to
     Landlord pursuant to this Lease are sometimes herein collectively referred
     to as the "Rent."


     Tenant shall pay to Landlord as Additional Rent an amount (the "Operating
Expense and Tax Escalation Amount") for each Calendar Year equal to the total of
the amount by which Tenant's Proportionate Share of Operating Expenses and Taxes
for such Calendar Year exceeds the Operating Expense and Tax Base Amount. The
Operating Expense and Tax Escalation Amount for each Calendar Year shall be paid
in estimated monthly installments. The amount of the estimated monthly
installments shall be reasonably estimated and adjusted from time to time by
Landlord by written notice to Tenant. As promptly as practicable following the
close of each Calendar Year, Landlord shall deliver to Tenant its statement
specifying the amount of Operating Expenses and Taxes for such Calendar Year,
the total estimated installments paid by Tenant for such Calendar Year and the
actual Operating Expense and Tax Escalation Amount for such Calendar Year. If
such statement shows that the actual Operating Expense and Tax Escalation Amount
exceeds the total estimated payments by Tenant, Tenant shall pay the deficiency
to Landlord within thirty (30) days after delivery of such statement. If such
statement shows that Tenant's estimated payments exceed the Operating Expense
and Tax Escalation Amount, the overage shall be credited against the next
accruing amounts due from Tenant under this Lease and the balance, if any, shall
be refunded to Tenant. All estimated monthly installments of Additional Rent due
under this Section shall be payable in advance, commencing on the Commencement
Date and thereafter on the first day of each and every month during the Term at
the same place as Base Rent. Tenant's obligation to pay the Additional Rent
provided for in this Section 4 which is accrued but not paid for periods prior
to the expiration or termination of the Term shall survive such expiration or
termination. For any Calendar Year which does not fall entirely within the Term,
Tenant shall be obligated to pay only a pro-rata share of the Operating Expense
and Tax Escalation Amount as hereinabove determined based on the number of days
of the Term falling within the Calendar Year in question.

5.  CONSTRUCTION AND POSSESSION.

     A.   Landlord's Obligations

          Landlord will proceed to complete the Premises in accordance with the
          Tenant Construction Agreement attached hereto as Exhibit C and tender

               safe occupancy and use of the Premises, including all building

               obligations under Section 7 hereof, shall be substantially

          (2)  A Certificate of Occupancy or similar written approval shall have

               occupancy of the Premises.


Landlord and Tenant agree that all alterations, improvements and additions made
to the Premises pursuant to the Tenant Construction Agreement, whether paid for
by Landlord or Tenant, shall without compensation to Tenant become Landlord's
property upon installation and shall remain Landlord's property at the
expiration of the Term or sooner termination of this Lease. period of such
occupancy prior to the scheduled Commencement Date at the rates set forth in
Section 3 and Section 4 hereof, pro-rated for the portion of Premises so
occupied. Under no circumstances shall the occurrence of any of the events
referred to in this Section 58 be deemed to accelerate the Termination Date.

     C.   Failure to Complete

          If Landlord fails to substantially complete its obligations under the
          Tenant Construction Agreement and tender the Premises to Tenant in
          accordance with Section 5A on or before the originally scheduled
          Commencement Date set forth in Section 1A(1), Landlord will not be in
          default or liable in damages to Tenant, nor will the obligations of
          Tenant hereunder be affected, provided, however, that:

          (1)  the Commencement Date shall automatically be extended by one day
               for each day of the period beyond the date set forth in Section
               1A(1) that Landlord fails to so substantially complete its
               obligations, less any portion of that period attributable to
               Tenant's delays as more particularly described in the Tenant
               Construction Agreement, and the Termination Date shall
               automatically be extended by the same number of days that the
               Commencement Date is so extended (except that if such extension
               would result in the Termination Date occurring on other than the
               last day of a calendar month, the Termination Date shall be
               extended by the additional number of days required in order for
               the Termination Date to occur on the last day of a calendar
               month); and

               with Section 5A on or before the date 6 months after the date set
               forth in Section 1A(1) (plus any period of delay caused by Tenant
               as described in the Tenant Construction Agreement), Tenant shall
               have the right to terminate this Lease and all obligations and
               rights created hereby by delivering written notice of termination
               to Landlord not more than thirty (30) days after such date.


Upon a termination under subparagraph (2) above, each party shall, upon the
other's request, execute and deliver an agreement in recordable form containing

          except as to items contained on a punch list to be prepared after an
          inspection made and signed by representatives of Landlord and Tenant

7.  SERVICES PROVIDED BY LANDLORD.

     A.   Description of Standard Services

          Landlord will furnish for Tenant and the Premises, subject to the
          other provisions of this Section 7, the following services:

          (1)  repair and maintenance of all structural elements of the Building
               and all general mechanical and electrical systems installed in
               the Building by Landlord, but excluding any systems installed in
               the Premises for Tenant's exclusive use. The cost of such repair
               and maintenance shall be included in Operating Expenses unless
               otherwise provided in this Lease or unless caused by the act or
               omission of Tenant, its agents, employees, contractors, licensees
               or invitees, in which latter case such cost shall be paid by
               Tenant within fifteen (15) days after written demand therefor;

          (2)  heating, ventilating and air conditioning (heating or cooling as
               required by the seasons), without special request from Tenant,
               from 8:00 a.m. to 6:00 p.m. on Monday through Friday, except
               holidays, at temperatures and in amounts as may, in the sole
               judgment of the Landlord, be reasonably required for comfortable
               use and occupancy under normal business operations with
               "Customary Office Equipment" (as used in this Lease, "Customary
               Office Equipment" shall include typewriters, adding machines,
               calculators, dictation recorders, small reproduction machines and

<PAGE>

               equipment but shall not include any machines, devices or
               equipment that adversely affect the temperature otherwise
               maintained in the Premises such as, e.g., data processing,
               computer or heavy-duty reproduction equipment). If Tenant shall

               hours and days specified above (the "After Hours HVAC"), Landlord
               will furnish the same for the hours specified in a request from
               Tenant (an "HVAC Request") and for this service Tenant will pay
               Landlord, upon receipt of Landlords statement, the hourly rate
               reasonably determined by Landlord from time to time; provided,
               however, that Tenant shall not be required to pay any such charge
               for heating, ventilation or air conditioning requested by Tenant
               in an HVAC Request for the hours from 8:00 a.m. to 1:00 p.m. on
               Saturdays (except holidays). Any HVAC Request by Tenant shall be
               made in such a manner and at such time as Landlord may from time
               to time establish for HVAC Requests, and Tenant acknowledges and
               agrees that Landlord may require that HVAC Requests be made by
               Tenant's authorized employees by direct code or card access to
               the computer system controlling the Building's mechanical system.
               As of the date of this Lease, Landlord's charge for After Hours
               HVAC is thirty-five and No/100 Dollars ($35.00) per hour, with a
               minimum charge of two (2) hours. Tenant acknowledges that
               Landlord shall have the right to change such After Hours HVAC
               rate from time to time as reasonably determined by Landlord;

          (3)  cold water for lavatory and toilet purposes, refrigerated water
               for drinking purposes and tempered water for lavatory purposes;
               all water service to be supplied from the regular supply of water
               to the Building at points of supply provided for general use of
               tenants of the Building through fixtures installed by Landlord;

          (4)  janitorial services to the Premises comparable to those
               janitorial services provided to tenants of similar first-class
               office buildings in the Denver metropolitan area;

          (5)  passenger elevators for access to and from the floor(s) on which
               the Premises are located, shuttle elevators for access to the
               parking garage, and freight elevator service but only when
               scheduled through the manager of the Building;

          (6)  toilet facilities in common with other tenants on the floors
               occupied by Tenant;

          (7)  electric lighting for all public areas and special service areas
               of the Building as reasonable and standard for first-class office
               buildings, including replacement of light bulbs and tubes;

          (8)  replacement of light bulbs in those Building standard lighting
               fixtures installed in the Premises; and

               operations within the Premises for regular business hours during

               for Customary Office Equipment).

     B.   Additional Services

          Landlord shall not be obligated to furnish any services or utilities
          other than those stated in Section 7A above. If Tenant should require
          electric current, water or any other energy in excess of the amounts
          provided by Landlord pursuant to Section 7A above, such excess
          electric, water or other energy requirement shall be supplied only
          with the consent of Landlord, which consent shall not be unreasonably
          withheld. If Landlord grants such consent, Tenant shall, on demand,
          pay all costs of meter service and installation of facilities
          necessary to measure and furnish the required excess capacity. Tenant
          shall also pay the entire cost of such additional electricity, water
          or other energy so required in the event Tenant installs any machines,
          equipment or devices in the Premises that do not constitute Customary
          Office Equipment and such machines, equipment or devices cause the
          temperature in the Premises, or any part thereof, to exceed the
          temperatures the Building's mechanical system would be able to
          maintain in the Premises were it not for such machines, equipment or
          devices, then Landlord reserves the right to install supplementary air
          conditioning units in the Premises, and the costs thereof, including
          the cost of installation and the cost of operation and maintenance
          thereof, shall be paid by Tenant to Landlord upon demand.
          Notwithstanding anything to the contrary contained herein, if Tenant
          should require electric current in excess of 2 watts per rentable
          square foot of the Premises, and Landlord installs a submeter for the
          Premises to measure such excess electricity use as set forth herein,
          Landlord shall provide Tenant with a monthly cost summary detailing
          Tenant's electrical usage based on Tenant's meter reading performed by
          the Public Service Company of Colorado (or its successor) and Tenant
          shall pay Landlord for such excess electrical use pursuant to such
          summary upon receipt of invoice. Landlord, in its sole discretion,
          shall have the right to, at all times, alter any and all utilities and
          the equipment relating thereto.

     C.   Interruption of Services

          Landlord does not warrant that the services provided for in this
          Section 7 will be free from any irregularity or stoppage. Landlord
          will use due diligence to resume the service upon any irregularity or
          stoppage; provided, however, no irregularity or stoppage of any of
          these services will create any liability for Landlord, constitute an
          eviction, actual or constructive, of Tenant, or cause any abatement of
          the Rent payable under this Lease or in any manner or for any purpose
          relieve Tenant from any of its obligations under this Lease.

8.   REPAIRS.

     A.   Repairs Within the Premises

          Subject to the terms of Sections 7A(1), 12 and 15 hereof, Tenant
          will, at Tenant's own expense, keep the Premises in good order, repair
          and condition at all times during the Term. Except for damage caused
          by Landlord, its employees, agents or contractors, Tenant shall
          promptly and adequately repair all damage to the Premises and replace
          or repair all damaged or broken fixtures and appurtenances, under the
          supervision and subject to the approval of the Landlord. All work done
          by Tenant or its contractors (which contractors shall be subject to
          Landlord's reasonable approval and shall not conflict with any union
          affiliation of Landlord's contractors) shall be done in a first-class
          workmanlike manner using only, grades of materials at least equal in
          quality to those which are included in Landlords standard improvements
          for the Building and shall comply with all insurance requirements and
          all applicable laws and ordinances and rules and regulations of
          governmental departments or agencies. At Landlord's option, Landlord
          may require that all work required

                                     - 9 -
<PAGE>

          to be performed by Tenant under this Section 8A be performed by
          Landlord or Landlord's contractor at Tenant's expense, in which case
          Tenant shall pay Landlord the cost of any such work, including an
          amount sufficient to reimburse Landlord for overhead and related
          expenses, forthwith upon being billed for the same as additional Rent
          hereunder.

     B.   Landlord's Entry

          If the Tenant fails to do so within a reasonable period of time or if
          Landlord deems such action necessary because of an actual or suspected
          emergency, Landlord may, but need not, make the repairs and
          replacements described in Section 8A, and Tenant shall pay Landlord
          the cost thereof, including an amount sufficient to reimburse Landlord
          for overhead and related expenses, forthwith upon being billed for
          same as additional Rent hereunder. Landlord may, but shall not be
          required to, enter the Premises at all reasonable times on prior
          notice (except in cases of actual or suspected emergency, in which
          case no prior notice shall be required) for the purpose of inspecting,
          repairing or maintaining the same. Landlord shall take reasonable
          steps in connection with such entry to minimize any disruption to
          Tenant's business or its use of the Premises.

     C.   Notice of Damage

          Tenant shall give prompt notice to Landlord of (a) any fire or other
          casualty in the Premises, (b) any damage to or defect in the Premises,
          including the fixtures, equipment and appurtenances thereof, for the
          repair of which Landlord might be responsible and (c) any damage to or
          defect in any parts or appurtenances of the Building's sanitary,
          electrical, heating, air conditioning, elevator or other systems
          located in or passing through the Premises or any part thereof.
          Landlord shall have no repair obligations whatsoever absent such
          notice or actual knowledge of such condition.

9.   ADDITIONS AND ALTERATIONS

     Tenant shall not, without the prior written consent of Landlord,
     make any alterations, improvements or additions to the Premises. If
     Landlord consents to such alterations, improvements or additions, it may
     impose such conditions with respect thereto as Landlord deems appropriate,
     including, without limitation, requiring Tenant to furnish Landlord with
     insurance against liabilities which may arise out of such work, security
     for Tenant's obligations to pay for such work, plans and specifications for
     Landlords approval prior to commencement of construction, copies of all
     permits necessary for such work and "as built" plans after completion of
     such work together with a complete breakdown of the cost of such work as
     required for purposes of Landlord's insurance or self-insurance. The work
     necessary to make any alterations, improvements or additions to the
     Premises shall be done at Tenants expense by employees of or contractors
     hired by Landlord. Tenant shall promptly pay, when due, the cost of all
     such work and of all decorating required by reason thereof. Tenant shall
     also pay to Landlord an amount sufficient, in Landlord's reasonable
     judgment, to reimburse Landlord for all of its overhead and related
     expenses allocable to such work. Upon completion, Tenant shall deliver to
     Landlord, to the extent not previously received by Landlord, evidence of
     payment, contractors' affidavits and full and final waivers of all liens
     for labor, services or materials. All alterations, improvements and
     additions to the Premises, whether temporary or permanent in character,
     made or paid for by Landlord or Tenant shall without compensation to Tenant
     become Landlord's property upon installation. All such alterations,
     improvements and additions shall, unless Landlord had expressly requested
     or approved their removal when Landlord consented to their installation (in
     which case Tenant shall remove the same as provided in Section 17), remain
     Landlord's property upon termination of this Lease by lapse of time or
     otherwise

                                     - 10 -
<PAGE>

     and shall be relinquished to Landlord in good condition, ordinary wear and
     tear excepted.

10.  COVENANT AGAINST LIENS

     Tenant covenants and agrees not to suffer or permit any lien of mechanics
     or materialmen or others to be placed against the Complex or the Premises
     with respect to work or services claimed to have been performed for or
     materials claimed to have been furnished to Tenant or the Premises. In case
     any such lien attaches, Tenant covenants and agrees to cause it to be
     immediately released and removed of record, unless Tenant has a good faith
     dispute as to the validity of such lien in which case Tenant may contest
     such lien by appropriate proceedings so long as Tenant deposits with
     Landlord a bond or other security in an amount reasonably acceptable to
     Landlord which may be used by Landlord to release such lien if Tenant's
     contest is abandoned or is unsuccessful. Upon final determination of any
     permitted contest, Tenant shall immediately pay any judgment rendered and
     cause the lien to be released.

11.  INSURANCE.

     A.   Waiver of Subrogation

          Landlord and Tenant each hereby waive any and every claim for recovery
          from the other for any and all loss of or damage to the Complex or the
          Premises or to the contents thereof, which loss or damage is of a type
          insurable under "all risk" hazard insurance policies available at the
          time such loss or damage was sustained. Inasmuch as this mutual waiver
          will preclude the assignment of any such claim by subrogation (or
          otherwise) to an insurance company (or any other person), Landlord and
          Tenant each agree to give written notice of the terms of this mutual
          waiver to each insurance company which has issued, or in the future
          may issue, a policy of hazard insurance to such party. Each party
          shall also have each such insurance policy properly endorsed, if
          necessary, to prevent the invalidation of such insurance coverage by
          reason of such waiver. If Landlord adopts a plan of self-insurance
          with respect to those portions of the Building Landlord may be
          obligated to repair or restore under Section 12A (and Landlord
          reserves the right to adopt such a plan) Landlord's waiver of claims
          contained in the first sentence of this paragraph will continue to be
          effective as long as Tenant's waiver of subrogation remains in effect.

     B.   Coverage

          Tenant agrees, at its cost, to obtain and keep in force during the
          Term the following described insurance, provided that Landlord may
          from time to time require reasonable increases in the limits set forth
          below:

          (1)  Liability Insurance.  Comprehensive general liability insurance
               with combined single limits of not less than $2,000,000 for
               personal injury and property damage occurring in or about or
               related to the use of the Premises and assumed contractual
               liability with respect to Tenant's obligations under Section 13,
               and employer's liability Insurance with limits of at least
               $500,000.

          (2)  Tenant's Personal Property. An "all risk" hazard insurance policy
               in the amount equal to the full replacement cost of Tenant's
               office furniture, trade fixtures, office equipment, merchandise
               and all other items of Tenant's property on the Premises.

          (3)  Worker's Compensation and Tenant's Contractors. A worker's (or
               workmen's) compensation insurance policy in at least the amount
               required by law. In addition, Tenant shall require any of
               Tenant's contractors that will perform work on the Premises to
               deliver to

                                     - 11 -
<PAGE>

               Landlord, prior to the commencement of such work, certificates of
               insurance evidencing that such contractors carry contractor's
               liability insurance in the amount of at least $500,000 and
               worker's (or workmen's) compensation insurance in at least the
               amount required by law.

          (4)  Form of Policies. All policies evidencing the coverage required
               under this Section 11B shall be issued by carriers with a rating
               of A-VII or better by Best's Key Rating Guide and licensed to do
               business in the State of Colorado and shall provide that (a) the
               coverage is primary and non-contributing to any insurance that
               may be carried by Landlord; (b) the coverage cannot be canceled,
               modified, reduced, or otherwise materially changed except after
               thirty (30) days' prior written notice to Landlord; and (c)
               Landlord, Homart Holding Company of Delaware Inc., Homart
               Development Co. and any other person or entity that Landlord may
               designate from time to time as additional insureds (except that
               such parties need not be so named in Tenant's worker's
               compensation policy). Tenant shall furnish Landlord with true
               copies of all policies or certificates of insurance evidencing
               such coverage promptly on receipt.

     C.   Avoid Action Increasing Rates

          Tenant shall comply with all applicable laws and ordinances, all
          orders and decrees of court and all requirements of other governmental
          authorities, and shall not, directly or indirectly, make any use of
          the Premises which may thereby be prohibited or be dangerous to person
          or property or which may jeopardize any insurance coverage, or may
          increase the cost of insurance or required additional insurance
          coverage. In no event shall Tenant permit in the Premises flammables
          such as gasoline, turpentine, kerosene, naphtha and benzene, or
          explosives or any other article of intrinsically dangerous nature, and
          in no event shall Tenant, its agents, employees or invitees bring such
          flammables or other articles into the Complex. If by reason of the
          failure of Tenant to comply with the provisions of this Section 11C,
          (i) any insurance coverage is jeopardized, Landlord shall have the
          option to terminate this Lease or (ii) insurance premiums are
          increased, Landlord may require Tenant to make immediate payment of
          the increased insurance premium as additional Rent hereunder.

12.  FIRE OR CASUALTY.

     A.   Restoration - Cancellation upon Major Damage

          If the Premises or the Building shall be damaged by fire or other
          casualty Landlord shall, promptly after learning of such damage,
          notify Tenant in writing of Landlord's estimate of the time necessary
          to repair or restore such damage. If Landlord reasonably estimates
          that repair or restoration of all of such damage that was caused to
          the Premises or to any other portion of the Building necessary for
          Tenant's occupancy cannot be completed within one hundred eighty (180)
          days from the date of such damage, then Tenant shall have the option
          to terminate this Lease. If such damage, in Landlord's opinion, has
          rendered all or a substantial portion of the Premises or the Building
          untenantable, Landlord shall have the option to terminate this Lease.
          Any option to terminate granted hereunder must be exercised by written
          notice to the other party given within ten (10) days after Landlord
          delivers to Tenant the notice of estimated repair time. If either
          party exercises its option to terminate this Lease, the Term shall
          expire and this Lease shall terminate ten (10) days after notice of
          termination is delivered; provided, however, that Rent for the period
          commencing on the date of such

                                     - 12 -
<PAGE>

          damage until the date this Lease terminates shall be reduced to the
          reasonable value of any use or occupation of the Premises by Tenant
          during such period. If neither party so terminates this Lease, then
          Landlord shall repair and restore such damage with reasonable
          promptness, subject to delays for insurance adjustments and delays
          caused by matters beyond Landlord's control. Landlord shall have no
          liability to Tenant and Tenant shall not be entitled to terminate this
          Lease in the event such repairs and restoration are not in fact
          completed within the time period estimated by Landlord.

     B.   Rent Abatement

          In the event any fire or casualty damage renders the Premises
          untenantable and if this Lease shall not be terminated pursuant to
          Section 12A hereof by reason of such damage, then Rent shall abate
          during the period beginning with the date of such damage and ending
          with the date when Landlord has substantially completed its
          obligations under this Section 12. Such abatement shall be in an
          amount bearing the same ratio to the total amount of Rent for such
          period as the untenantable portion of the Premises bears to the entire
          Premises. In no event will Landlord be liable for any inconvenience or
          annoyance to Tenant or injury to the business of Tenant resulting in
          any way from damage caused by fire or other casualty or the repair of
          such damage, provided however that, to the extent Tenant remains in
          possession of a portion of the Premises, Landlord will take all
          reasonable steps to minimize the disruption to Tenant's business and
          use of such portion of the Premises during the period of repair.

13.  WAIVER OF CLAIMS - INDEMNIFICATION

     (a) To the extent not prohibited by law, Landlord and its parent and
     affiliated corporations, its and their partners, venturers, directors,
     officers, agents, servants and employees shall not be liable for, and
     Tenant waives all claims for, any damages to person or property, or
     resulting from the loss of use thereof, or any loss of profits or damages
     from business interruption, sustained by Tenant or by Tenant's officers,
     agents, servants or employees due to the Building or the Complex or any
     part thereof or any appurtenances thereof becoming out of repair, or due to
     the happening of any accident or event in or about the Building or Complex,
     or due to any act or neglect of any tenant or occupant of the Building or
     Complex or of any other person. This provision shall apply particularly
     (but not exclusively) to damage caused by gas, electricity, snow, frost,
     steam, sewage, sewer gas or odors, fire, water or by the bursting or
     leaking of pipes, faucets, sprinklers, plumbing fixtures, and windows, and
     shall apply without distinction as to the person whose act or neglect was
     responsible for the damage and whether the damage was due to any of the
     causes specifically enumerated above or to some other cause of an entirely
     different kind. Tenant further agrees that all personal property upon the
     Premises, or upon loading docks, receiving and holding areas or parking
     areas, of the Building or the Complex, shall be at the risk of Tenant only,
     and that Landlord shall not be liable for any loss or damage thereto or
     theft thereof. Without limitation of any other provisions hereof and to the
     extent not prohibited by law, Tenant agrees to defend, protect, indemnity
     and save harmless Landlord and its parent and affiliated corporations, its
     and their partners, venturers, directors, officers, agents, servants and
     employees from and against all fines, suits, costs, demands, actions,
     judgments, claims, liabilities, losses, damages or expenses ("Liabilities")
     made or asserted against or incurred by an Indemnitee and attributable to
     the negligence, willful misconduct or breach of this Lease by Tenant or its
     officers, servants, agents, employees, contractors, suppliers, workmen or
     invitees. If any such proceeding is brought against an Indemnitee, Tenant
     will retain counsel reasonably satisfactory to Landlord to defend the
     Indemnitee at Tenant's sole cost and

                                     - 13 -
<PAGE>

     expense. All such costs and expenses, including attomeys' fees and court
     costs, shall be a demand obligation owing by Tenant to Landlord. Tenant's
     obligations under this Section shall survive the termination or expiration
     of this Lease;


     (b) Landlord will Indemnify and hold and save Tenant, its affiliates and
their respective Employees harmless from all Liabilities to the extent such
Liabilities shall arise directly and solely from Landlord's gross negligence or
intentional act or omission. If any such proceeding is brought against an
indemnitee, Landlord will retain counsel reasonably satisfactory to Tenant to
defend the indemnitee at Landlord's sole cost and expense. All such costs and
expenses, including reasonable attorneys' fees and court costs, shall be a
demand obligation owing by Landlord to Tenant. Landlord's obligations under this
Section shall survive the termination or expiration of this Lease.

14.  NONWAIVER

     No waiver of any provision of this Lease shall be implied by any failure of
     Landlord to enforce any remedy on account of the violation of such
     provision even if such violation be continued or repeated subsequently, and
     no express waiver shall affect any provision other than the one specified
     in such waiver and that one only for the time and in the manner
     specifically stated.

15.  CONDEMNATION

     If the whole or substantially the whole of the Building, the Premises or
     the parking facilities in the Complex is taken for any public or
     quasi-public use under any governmental law, ordinance or regulation or by
     right of eminent domain or is sold to the condemning authority in lieu of
     condemnation, then this Lease will terminate as of the date when physical
     possession of the Building, the Premises or the parking facilities in the
     Complex is taken by the condemning authority. If less than the whole or
     substantially the whole of the Building, the Premises or the parking
     facilities in the Complex is thus taken or sold and if, after such partial
     taking, in Landlords' reasonable judgment, alteration or reconstruction of
     the Complex is not economically justified, Landlord (whether or not the
     Premises are affected thereby) may terminate this Lease by giving written
     notice to Tenant within sixty (60) days after the taking. If over fifty
     percent (50%) of the Premises is thus taken or sold, Tenant may terminate
     this Lease if, and only if, in Tenant's reasonable judgment, the Premises
     cannot be operated by Tenant in an economically viable fashion because of
     such partial taking. Such termination by Tenant must be exercised by
     written notice to Landlord given not later than sixty (60) days after
     Tenant is notified of the taking of the Premises. Termination by Landlord
     or Tenant shall be effective as of the date when physical possession of the
     applicable portion of the Complex, the Building or the Premises is taken by
     the condemning authority. If neither Landlord nor Tenant elects to
     terminate this Lease upon a partial taking of a portion of the Premises,
     the Rent payable under this Lease will be diminished by an amount allocable
     to the portion of the Premises which was so taken or sold. If this Lease is
     not terminated upon a partial taking, Landlord will, at Landlord's sole
     expense, promptly restore and reconstruct the Complex, the Building and the
     Premises to substantially their former condition to the extent that the
     same may be feasible. Landlord in no event shall be required to spend for
     such restoration or reconstruction an amount in excess of the net amount
     received by Landlord as compensation or damages for the part of the
     Complex, the Building or the Premises so taken. As between the parties to
     this Lease, Landlord will be entitled to receive all of the compensation
     awarded upon a taking of any part or all of the Complex, the Building or
     the Premises including any award for the value of any unexpired term of
     this Lease and Tenant will not be entitled to and expressly waives all
     claim to any compensation for the unexpired term of this Lease. The
     foregoing shall not in any way restrict Tenant from asserting a claim in a
     separate proceeding against the condemning authority (if and to the extent
     permitted by law) for any damages resulting from the taking of Tenant's
     trade

                                     - 14 -
<PAGE>

     fixtures or for moving expenses or business relocation expenses incurred as
     a result of such condemnation.

16.  ASSIGNMENT AND SUBLETTING

     Tenant shall not, without the prior written consent of Landlord, (i)
     assign, convey or mortgage this Lease or any interest hereunder; (ii)
     suffer to occur or permit to exist any assignment of this Lease, or any
     lien upon Tenant's interest, voluntarily, involuntarily or by operation of
     law; (iii) sublet the Premises or any part thereof; or (iv) permit the use
     of the Premises by any parties other than Tenant and its employees. For
     purposes of the preceding sentence, any change in ownership of Tenant or of
     any guarantor of Tenant's obligations under this Lease (a "Guarantor")
     shall be deemed to be an assignment of this Lease; a "change in ownership"
     shall be deemed to have occurred (a)(i) for a publicly traded corporation,
     when there is a change of effective control; (ii) for any other entity, in
     the event of any circumstance where the voting interest of any party or
     group of parties increases or decreases by more than one-third of the
     entire voting interest; or (b) upon the distribution of over fifty percent
     (50%) of any entity's assets, or if the value of assets sold (net of
     undistributed consideration received) exceeds fifty percent (50%) of asset
     value. Landlord's consent to any assignment, subletting or transfer shall
     not constitute a waiver of Landlord's right to withhold its consent to any
     future assignment, subletting or transfer.


     Tenant shall give Landlord written notice of any proposed sublease or
assignment which notice shall contain the name of the proposed sublessee or
assignee and proposed principal terms thereof. With respect to any proposed
assignment of all of Tenant's interest under this Lease or any proposed sublease
of all of the Premises, which proposed assignment or sublease is to occur
subsequent to eighteen months after the Commencement Date, Landlord agrees that
it shall not unreasonably withhold its consent to such assignment or sublease;
provided, however, that reasonable grounds for the withholding of consent shall
include, without limitation, the proposed assignee's or subtenant's insufficient
financial capacity or business experience to perform Tenant's obligations under
this Lease or its poor business reputation.

     Upon any assignment or subletting by Tenant, (i) the original Tenant and
any Guarantor shall not be released from any covenant or obligation under this
Lease, and (ii) Landlord shall be entitled to receive and collect, either from
Tenant or directly from the assignee or subtenant, all of the consideration, if
any, that the assignee or subtenant is required to pay for the use and enjoyment
of Tenant's rights under this Lease in addition to the amounts payable by Tenant
to Landlord hereunder (whether payable by such assignee or subtenant in monthly
installments, in a lump sum, or otherwise).

17.  SURRENDER OF POSSESSION

     Upon the expiration of the Term or upon the termination of Tenant's
     right of possession, Tenant shall forthwith surrender the Premises to
     Landlord in good order, repair and condition, ordinary wear and damage by
     fire or other casualty excepted. All alterations, improvements and
     additions to the Premises, made or paid for by Landlord or Tenant, shall
     without compensation to Tenant become Landlord's property upon
     installation. Except as provided in Section 9 to the contrary, all such
     alterations, improvements and additions shall remain Landlord's property at
     the termination of this Lease by lapse of time or otherwise and shall be
     relinquished to Landlord in good condition, ordinary wear and damage by
     fire or other casualty excepted. Tenant agrees to remove at the termination
     of the Term or of its right of possession the following items of property:
     office furniture, trade fixtures, office equipment and all other items of
     Tenant's property or temporary improvements on the Premises, and Tenant
     shall pay to Landlord upon demand the cost of repairing any damage to the
     Premises and to the Building caused by any such removal. If Tenant shall
     fail or

                                     - 15 -
<PAGE>

     refuse to remove any such property from the Premises, Tenant shall be
     conclusively presumed to have abandoned the same, and title thereto shall
     thereupon pass to Landlord without any cost either by set-off, credit,
     allowance or otherwise, and Landlord may at its option accept the title to
     such property or at Tenant's expense may (i) remove the same or any part in
     any manner that Landlord shall choose, and (ii) store, destroy or otherwise
     dispose of the same without incurring liability to Tenant or any other
     person.

18.  PERSONAL PROPERTY.

     A.   Responsibility

          Tenant shall be solely responsible for all costs and expenses related
          to personal property used or stored in the Premises. Without limiting
          the foregoing, Tenant shall pay any taxes or other governmental
          impositions levied upon or assessed against such personal property, or
          upon Tenant for the ownership or use of such personal property, on or
          before the due date for payment thereof. Such personal property taxes
          or impositions are not included in Taxes or the Tax Base Amount.

     B.   Landlord's Lien

          In addition to any statutory landlord's lien and in order to secure
          payment of all Rent and other sums of money becoming due from Tenant,
          and to secure payment of any damages or loss which Landlord may suffer
          by reason of the breach by Tenant of any covenant, agreement or
          condition contained in this Lease, Tenant hereby grants to Landlord a
          security interest in and an express contractual lien upon all goods,
          wares, equipment, fixtures, furniture, improvements and other personal
          property of Tenant presently or which may hereafter be situated on the
          Premises and all Proceeds therefrom. Tenant's Personal property may
          not be removed from the Premises without Landlord's consent until all
          arrearages in Rent as well as any and all other sums of money then due
          to Landlord have been paid and all the Covenants, agreements and
          conditions imposed upon Tenant have been fully Complied with and
          performed by it. Upon the occurrence of an "Event of Default" (as
          defined in Section 24A), in addition to any other available remedies,
          Landlord shall have all the rights of a secured party under the
          Colorado Uniform Commercial Code with respect to the property covered
          by the security interest herein granted. Upon request by Landlord,
          Tenant agrees to execute and deliver to Landlord such financing
          statements as may be required to perfect the security interest of
          Landlord in the aforementioned Property and proceeds thereof.

19.  HOLDING OVER

     If Tenant shall hold over after the expiration of the Term or of Tenant's
     right of possession, without written agreement providing otherwise, Tenant
     shall be deemed to be a tenant from month to month, at a monthly Base Rent,
     payable in advance, equal to two hundred percent (200%) of monthly Base
     Rent payable during the last year of the Term, and Tenant shall be bound by
     all of the other terms, covenants and agreements of this Lease as the same
     may apply to a month-to-month tenancy. Nothing contained herein shall be
     Construed to give Tenant the right to hold over at any time, and Landlord
     may exercise any and all remedies at law or in equity to recover possession
     of the Premises, as well as any damages incurred by Landlord, due to
     Tenant's failure to vacate the Premises and deliver possession to Landlord
     as herein provided.

20.  ESTOPPEL CERTIFICATE

     Tenant agrees that from time to time upon not less than ten (10) days'
     prior request by Landlord, Tenant will deliver to Landlord a statement in
     writing certifying (i) that this Lease is unmodified and in full force and
     effect (or if there have been modifications that the Lease as modified is
     in full

                                     - 16 -
<PAGE>

     force and effect); (ii) the dates on which the Commencement Date occurred
     and the Termination Date will occur; (iii) the dates on which Tenant began
     paying Rent and that no Rent has been paid in advance of the required
     payment dates; (iv) that neither the Tenant nor the Landlord is in default
     under any provision of this Lease, or, if a default exists, the nature
     thereof in detail; (v) that Tenant has no existing defenses or off-sets to
     the enforcement of the Lease or, if any, specifying same; and (vi) provided
     such events have occurred, that Tenant has accepted and occupied the
     Premises and that the Premises have been completed in accordance with the
     terms hereof. It is intended that any such statement may be relied upon by
     any prospective purchaser or tenant of the Building, any mortgage or
     prospective mortgagees thereof, or any prospective assignee of any mortgage
     thereon.

21.  OBLIGATIONS TO MORTGAGEES.

     A.   Subordination

          At Landlord's option, this Lease may be made subject and subordinate
          to future ground or underlying leases of the Land and to the lien of
          any mortgages or trust deeds, hereafter in force against the Land,
          Complex or Building, or any of them, and to all renewals, extensions,
          modifications, consolidation and replacements thereof, and to all
          advances made or hereafter to be made upon the security of such
          mortgages or trust deeds. Tenant shall at Landlord's request execute
          such further instruments or assurances as Landlord may reasonably deem
          necessary to evidence or confirm the subordination of this Lease to
          any such mortgages, trust deeds, ground leases or underlying leases,
          or, if requested by any mortgagee or ground lessor, to make Tenant's
          interest in this Lease superior to the interest of such mortgagee or
          ground lessor. It is further agreed that upon the request of the
          mortgagee or trustee, if the mortgage or trust deed shall be
          foreclosed, or the transferee if the Building shall be conveyed in
          lieu of foreclosure, Tenant will attorn, as Tenant under this Lease,
          to the purchaser at any foreclosure sale or transferee under such
          conveyance, or upon request of the ground lessor, if any ground or
          underlying lease shall be terminated, Tenant will attorn, as Tenant
          under this Lease, to the ground lessor, and, in either case, Tenant
          will execute such instruments as may be necessary or appropriate to
          evidence such attornment.

     B.   Notice to Landlord and Mortgagee

          In the event of any act or omission by Landlord which would give
          Tenant the right to damages from Landlord or the right to terminate
          this Lease, Tenant will not sue for such damages or exercise any such
          right to terminate until (i) it shall have given written notice of the
          act or omission to Landlord and to the holder(s) of the indebtedness
          or other obligations secured by any mortgage or deed of trust
          affecting the Premises or of any ground or underlying lease, if the
          name and address of such holder(s) have been furnished to Tenant, and
          (ii) the lesser of thirty (30) days or the applicable grace period
          hereunder for remedying the act or omission has elapsed following the
          giving of the notice, during which time Landlord and such holder(s),
          or either of them, their agents or employees, will be entitled to
          enter upon the Premises and do therein whatever may be necessary to
          remedy the act or omission.

22.  CERTAIN RIGHTS RESERVED BY LANDLORD

     Landlord shall have the following rights, each of which Landlord may
     exercise without notice to Tenant (except as expressly provided below) and
     without liability to Tenant for damage or injury to property, person or
     business on account of the exercise thereof, and the exercise of any such
     rights shall not be deemed to constitute an eviction or disturbance of
     Tenant's use or possession of the Premises and shall not give rise to any
     claim for set-off or abatement of rent or any other claim, provided,
     however,

                                     - 17 -
<PAGE>

     that Landlord takes reasonable steps to minimize any disruption to Tenant's
     business or use of the Premises:

          (1)  to change the name or street address of the Complex or the
               Building, with notice to Tenant;

          (2)  to install, affix and maintain any and all signs on the exterior
               and on the interior of the Building or anywhere on Land or in the
               Complex (and Tenant agrees not to place or maintain any sign or
               other advertising matter outside the Premises or inside the
               Premises so as to be visible from outside the Premises);

          (3)  to decorate or to make repairs, alterations, additions, or
               improvements, whether structural or otherwise, in and about the
               Building or Complex, or any part thereof, and for such purposes
               to enter upon the Premises, and, during the continuance of any of
               such work, to temporarily close doors, entryways, public space
               and corridors in the Building and to interrupt or temporarily
               suspend services or use of facilities, all without affecting any
               of Tenant's obligations hereunder, so long as Landlord has given
               Tenant reasonable prior notice of any such actions in the
               Premises (provided, however, that no such prior notice shall be
               required in the case of emergency or suspected emergency).
               Landlord shall take reasonable steps in connection with such
               actions to minimize any disruption to Tenant's business or its
               use of the Premises;

          (4)  to the extent permitted by law, to retain at all times, and to
               use in appropriate instances, keys to all doors within and into
               the Premises. Tenant agrees to purchase only from Landlord
               additional duplicate keys as required, to change no locks, and
               not to affix locks on doors without the prior written consent of
               Landlord (notwithstanding the provisions for Landlord's access to
               portions of the Premises, Tenant relieves and releases the
               Landlord of all responsibility arising out of theft, robbery and
               pilferage). Upon the expiration of the Term or of Tenant's right
               to possession, Tenant shall return all keys to Landlord and shall
               disclose to Landlord the combination of any safes, cabinets or
               vaults left in the Premises;

          (5)  to designate Building standard window coverings for all windows
               in the Building and to designate and approve, prior to
               installation, all types of additional window shades, blinds or
               draperies, if any;

          (6)  to approve the weight, size and location of safes, vaults and
               other heavy equipment and articles in and about the Premises and
               the Building (so as not to exceed the legal live load per square
               foot designated by the structural engineers for the Building),
               and to require all such items and furniture and similar items to
               be moved into or out of the Building and Premises only at such
               times and in such manner as Landlord shall direct in writing.
               Movements of Tenant's property into or out of the Building and
               within the Building are entirely at the risk and responsibility
               of Tenant and Landlord reserves the right to require permits
               before allowing any property to be moved into or out of the
               Building;

          (7)  to show the Premises to prospective tenants at reasonable hours
               and upon reasonable notice, which such notice may be given by

                                     - 18 -

               telephone to Tenant's office manager or via facsimile
               transmission during the last six months of the Term; and

          (8)  to erect, use and maintain unexposed pipes, ducts, wiring and
               conduits, and appurtenances thereto, in and through the Premises.

23.  RULES AND REGULATIONS

     Tenant covenants and agrees to keep and observe the rules and regulations
     attached to this Lease as Exhibit D and made a part hereof. Landlord shall
     have the right from time to time to amend such rules and regulations and to
     prescribe additional rules and regulations which, in its sole judgment, may
     be desirable for the use, entry, operation and management of the Premises,
     the Building and the Complex, each of which additional rules and
     regulations shall be come a part of this Lease. Tenant shall comply with
     such rules and regulations provided, however, that such rules and
     regulations shall not contradict or abrogate any right or privilege herein
     expressly granted to Tenant.

24.  DEFAULT AND REMEDIES.

     A.   Events of Default

          Each of the following shall constitute an "Event of Default" under
          this Lease:

          (1)  Failure to Pay Rent or Other Amounts. If Tenant fails to pay when
               due, Base Rent, Additional Rent, or any other Rent or amounts
               payable by Tenant under the terms of this Lease, and such failure
               shall continue for five (5) days after written notice from
               Landlord to Tenant of such failure, provided however, that with
               respect to Base Rent and Additional Rent, Tenant shall not be
               entitled to more than two notices of such failure during any
               Calendar Year and if, after two such notices are given in any
               Calendar Year, Tenant fails, during such Calendar Year, to pay
               any such amounts when due, such failure shall constitute an Event
               of Default without further notice by Landlord or additional cure
               period.

          (2)  Violation of Lease Terms. If Tenant breaches or fails to comply
               with any provision of this Lease applicable to Tenant, and such
               breach or failure to comply is not covered by the provisions of
               Section 24A(1) above and continues for a period of twenty (20)
               days after notice thereof by Landlord to Tenant, or, if such
               breach or failure to comply cannot be reasonably cured within
               such twenty (20)-day period, if Tenant shall not in good faith
               commence to cure such breach or failure to comply within such
               twenty (20)-day period or shall not diligently complete such cure
               within sixty (60) days after such notice from Landlord; provided,
               however, that if such breach or failure to comply causes or
               results in (i) a dangerous condition on the Premises, Building or
               Complex, (ii) any insurance coverage carried by Landlord or
               Tenant with respect to the Premises, Building or Complex being
               jeopardized, or (iii) a material disturbance to another tenant of
               the Complex, then an Event of Default shall exist if such breach
               or failure to comply is not cured as soon as reasonably possible
               after notice thereof by Landlord to Tenant, and in any event is
               not cured within thirty (30) days after such notice. For purposes
               of this Section 24A(2), financial inability shall not be deemed a
               reasonable ground for failure to immediately cure any breach of,
               or failure to comply with, the provisions of this Lease.

          (3)  Nonoccurrence of Demised Premises. If Tenant shall fail to occupy
               and use the Premises within fifteen (15) days after commencement
               of

                                     - 19 -
<PAGE>

               the Term or shall leave the Premises unoccupied for fifteen (15)
               consecutive days or shall vacate and abandon the Premises.

          (4)  Transfer of Interest Without Consent. If Tenant's interest under
               this Lease or in the Premises shall be transferred to or pass to
               or devolve upon any other party in violation of the provisions of
               Section 16.

          (5)  Execution and Attachment Against Tenant. If Tenant's interest
               under this Lease or in the Premises shall be taken upon execution
               or by other process of law directed against Tenant, or shall be
               subject to any attachment at the instance of any creditor or
               claimant against Tenant and said attachment shall not be
               discharged or disposed of within fifteen (15) days after the levy
               thereof.

          (6)  Bankruptcy or Related Proceedings. If Tenant shall file a
               petition in bankruptcy or insolvency or for reorganization or
               arrangement under the bankruptcy laws of the United States or
               under any similar act of any state, or shall voluntarily take
               advantage of any such law or act by answer or otherwise, or shall
               be dissolved or shall make an assignment for the benefit of
               creditors or if involuntary proceedings under any such bankruptcy
               or insolvency law or for the dissolution of Tenant shall be
               instituted against Tenant or a receiver or trustee shall be
               appointed for the Premises or for all or substantially all of the
               property of Tenant, and such proceedings shall not be dismissed
               or such receivership or trusteeship vacated within sixty (60)
               days after such institution or appointment.

     B.   Landlord's Remedies

          Time is of the essence hereof. Upon the occurrence any Event of
          Default, Landlord shall have the right, at Landlord's election, then
          or at time thereafter, to exercise any one or more of the following
          remedies:

          (1)  Cure by Landlord. Upon an Event of Default, Landlord may, at
               Landlord's option, but without obligation to do so, and without
               releasing Tenant from any obligations under this Lease, make any
               payment or take any action as Landlord may deem necessary or
               desirable to cure any such Event of Default in such manner and to
               such extent as Landlord may deem necessary or desirable. Landlord
               may do so without demand on, or written notice to, Tenant and
               without giving Tenant an opportunity to cure such Event of
               Default. Tenant covenants and agrees to pay to Landlord, within
               ten (10) days after demand, all advances, costs and expenses of
               Landlord in connection with the making of any such payment or the
               taking of any such action, including reasonable attorney's fees,
               together with interest at the rate described in Section 29B, from
               the date of payment of any such advances, costs and expenses by
               Landlord.

          (2)  Termination of Lease and Damages. Upon an Event of Default,
               Landlord may terminate this Lease, effective at such time as may
               be specified by written notice to Tenant, and demand (and, it
               such demand is refused, recover) possession of the Premises from
               Tenant. Tenant shall remain liable to Landlord for damages in an
               amount equal to the Base Rent, Additional Rent and other Rent and
               sums which would have been owing by Tenant hereunder 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

                                     - 20 -
<PAGE>

               subsequent to such termination, after deducting all Landlord's
               expenses in connection with such recovery of possession or
               reletting. Landlord shall be entitled to collect and receive such
               damages from Tenant on the days on which the Base Rent,
               Additional Rent and other Rent and amounts would have been
               payable if this Lease and not been terminated. Alternatively, at
               the option of Landlord, Landlord shall be entitled to recover
               forthwith from Tenant, as damages for loss of the bargain and not
               as a penalty, an aggregate sum which, at the time of such
               termination of this Lease, represents the present value of the
               excess, if any of (a) the aggregate of the Base Rent, Additional
               Rent and all other Rent and sums payable by Tenant hereunder that
               would have accrued for the balance of the Term (such aggregate
               shall be calculated by assuming that the monthly installment of
               Additional Rent due for the month in which termination occurs
               shall remain the same for the balance of the Calendar Year in
               which termination occurs and that the total amount of Additional
               Rent payable for the succeeding Calendar Years remaining in the
               Term if this Lease had not been terminated shall increase by
               eight percent (8%) per Calendar Year over the amount of
               Additional Rent payable for the Calendar Year in which
               termination occurs), over (b) the amount, if any, of such Base
               Rent, Additional Rent and other Rent and sums which Tenant
               establishes Landlord can reasonably expect to recover by
               reletting the Premises for the remainder of the Term, taking into
               consideration loss of rent while finding a new tenant, tenant
               improvements and rent abatements necessary to secure a new
               tenant, leasing brokers' commissions and other costs which
               Landlord might incur in leasing the Premises to a new tenant plus
               any other sum of money and damages owed by Tenant to Landlord for
               events or actions occurring prior to the date of termination.
               Such present value shall be calculated at the rate commonly
               called the discount rate for ninety (90)-day commercial paper in
               effect at the Federal Reserve Bank of Chicago on the date of
               termination of this Lease.

          (3)  Repossession and Reletting. Upon an Event of Default, Landlord
               may reenter and take Possession of the Premises or any part
               thereof, without demand or notice, and repossess the same and
               expel Tenant and any party claiming by, under or through Tenant,
               and remove the effects of both using such force for such purposes
               as may be necessary, without being liable for prosecution on
               account thereof or being deemed guilty of any manner of trespass,
               and without prejudice to any remedies for arrears of rent or
               right to bring any proceeding for breach of covenants or
               conditions. No such reentry or taking possession of the Premises
               by Landlord shall be construed as an election by Landlord to
               terminate this Lease unless a written notice of such intention is
               given to Tenant. No notice from Landlord hereunder or under a
               forcible entry and detainer statute or similar law shall
               constitute an election by Landlord to terminate this Lease unless
               such notice specifically so states. Landlord reserves the right,
               following any reentry or reletting, to exercise its right to
               terminate this Lease by giving Tenant such written notice, in
               which event the Lease will terminate as specified in said notice.
               After recovering possession of the Premises, Landlord may, from
               time to time, but shall not be obligated to, relet the Premises,
               or any part thereof, for the account of Tenant, for such term or
               terms and on such conditions

                                     - 21 -
<PAGE>

               and upon such other terms as Landlord, in its discretion, may
               determine Landlord may make such repairs, alterations or
               improvements as Landlord may consider appropriate to accomplish
               such reletting, and Tenant shall reimburse Landlord upon demand
               for all costs and expenses, including attorneys' fees, which
               Landlord may incur in connection with such reletting. Landlord
               may collect and receive the rents for such reletting but Landlord
               shall in no way be responsible or liable for any failure to relet
               the Premises, or any part thereof, or for many failure to collect
               any rent due upon such reletting. Notwithstanding Landlords
               recovery of possession of the Premises, Tenant shall continue to
               pay on the dates herein specified, the Base Rent, Additional Rent
               and other Rent and amounts which would be payable hereunder if
               such repossession had not occurred, less a credit for the net
               amounts, if any, actually received by Landlord through any
               reletting of the Premises.

          (4)  Landlord's Bankruptcy Remedies. Nothing contained in this Lease
               shall limit or prejudice the right of Landlord to prove and
               obtain as liquidated damages in any bankruptcy, insolvency,
               receivership, reorganization or dissolution proceeding, an amount
               equal to the maximum allowable by any statute or rule or law
               governing such proceeding in effect at the time when such damages
               are to be proved, whether or not such amount be greater, equal or
               less than the amounts recoverable, either as damages or rent,
               under this Lease.


     Exercise of any of the remedies of Landlord under this Lease shall not
prevent the concurrent or subsequent exercise of any other remedy provided for
in this Lease or otherwise available to Landlord at law or in equity.

25.  EXPENSES OF ENFORCEMENT

     Tenant shall pay upon demand all Landlord's costs, charges and expenses,
     including the fees and out-of-pocket expenses of counsel, agents and others
     retained by Landlord, incurred in successfully enforcing Tenant's
     obligations hereunder. Landlord shall pay upon demand all Tenants costs,
     charges and expenses, including the fees and out-of-pocket expenses of
     counsel, agents and others retained by Tenant, incurred in successfully
     enforcing Landlord's obligations hereunder.

26.  COVENANT OF QUIET ENJOYMENT

     Landlord covenants that Tenant, on paying the Rent, charges for services
     and other payments herein reserved, and, on keeping, observing and
     performing all the other terms, covenants, conditions, provisions and
     agreements herein contained on the part of Tenant to be kept, observed, and
     performed, shall, during the Term, have quiet and peaceable possession of
     the Premises subject to the terms, covenants, conditions, provisions, and
     agreements hereof, and such possession shall not be disturbed by Landlord
     or by any person claiming by, through or under Landlord.

27.  SECURITY DEPOSIT

     Tenant hereby deposits with Landlord as the "Security Deposit" the amount
     set forth in Section 1A(10) as security for the prompt, full and faithful
     performance by Tenant of each and every provision of this Lease and of all
     obligations of Tenant hereunder.

          (1)  If Tenant fails to perform any of its obligations hereunder,
               Landlord may use, apply or retain the whole or any part of the
               Security Deposit for the payment of (i) any Rent or other sums of
               money which Tenant may not have paid when due, (ii) any sum
               expended by Landlord on Tenant's behalf in accordance with the
               provisions of

                                     - 22 -
<PAGE>

               this Lease, or (iii) any sum which Landlord may expend or be
               required to expend by reason of Tenant's default, including,
               without limitation, any damage or deficiency in or from the
               reletting of the Premises as provided in Section 24. The use,
               application or retention of the Security Deposit, or any portion
               thereof, by Landlord shall not prevent Landlord from exercising
               any other right or remedy provided by this Lease or by law (it
               being intended that Landlord shall not first be required to
               proceed against the Security Deposit) and shall not operate as a
               limitation on any recovery to which Landlord may otherwise be
               entitled. If any portion of the Security Deposit is used, applied
               or retained by Landlord for the purposes set forth above, Tenant
               agrees, within ten (10) days after the written demand therefor is
               made by Landlord, to deposit cash with the Landlord in an amount
               sufficient to restore the Security Deposit to its original
               amount.

          (2)  If Tenant shall fully and faithfully comply with all of the
               provisions of this Lease, the Security Deposit, or any balance
               thereof, shall be returned to Tenant without interest within
               sixty (60) days after the expiration of the Term or after the
               date on which Tenant vacates the Premises, whichever shall occur
               last. In the absence of evidence satisfactory to Landlord of any
               permitted assignment of the right to receive the Security
               Deposit, or of the remaining balance thereof, Landlord may return
               the same to the original Tenant, regardless of one or more
               assignments of Tenant's interest in this Lease or the Security
               Deposit. In such event, upon the return of the Security Deposit,
               or the remaining balance thereof, to the original Tenant,
               Landlord shall be completely relieved of liability under this
               Section 27 or otherwise with respect to the Security Deposit.

          (3)  Tenant acknowledges that Landlord has the right to transfer its
               interest in the Land and Building and in this Lease and Tenant
               agrees that in the event of any such transfer, Landlord shall
               have the right to transfer the Security Deposit to the
               transferee. Upon written acknowledgment of transferee's receipt
               of such Security Deposit, Landlord shall thereby be released by
               Tenant from all liability or obligation for the return of such
               Security Deposit and Tenant agrees to look solely to such
               transferee for the return of the Security Deposit.

28.  REAL ESTATE BROKER

     The Tenant represents that the Tenant has dealt with no broker in
     connection with this Lease other than the broker or brokers, if any, named
     in Section 1A(11) and that insofar as the Tenant knows, no other broker or
     finder negotiated this Lease or is entitled to any commission or fee in
     connection herewith. Tenant agrees to indemnify, defend and hold Landlord
     free and harmless from and against all claims for broker's commissions or
     finder's fees by any person claiming to have been retained by Tenant in
     connection with this transaction, other than the broker or brokers, if any,
     named in Section 1A(11).

29.  MISCELLANEOUS.

     A.   Rights Cumulative

          All rights and remedies of the parties under this Lease shall be
          cumulative and none shall exclude any other rights and remedies
          allowed by law.

     B.   Late Payment Penalty and Interest

          Tenant covenants and agrees to pay to Landlord a late payment
          penalty for any installment of Base Rent or

                                     - 23 -
<PAGE>

          Additional Rent that Tenant fails to pay when due in an amount equal
          to the greater of One Hundred and No/100 Dollars ($100.00) or five
          percent (5%) of such installment provided that no such late payment
          penalty shall be due in the event payment of such installment of Base
          Rent or Additional Rent is made by Tenant within five (5) days after
          written notice from Landlord to Tenant of Tenant's failure to pay such
          rent when due. In addition, all Rent and other payments due hereunder
          shall upon becoming due under this Lease and remaining unpaid when due
          bear interest until paid at the rate of eighteen percent (18%) per
          annum, compounded monthly.

     C.   Binding Effect

          Each of the provisions of this Lease shall extend to and shall, as the
          case may require, bind or inure to the benefit not only of Landlord
          and of Tenant, but also of their respective successors or assigns,
          provided this clause shall not permit any assignment by Tenant
          contrary to the provisions of Section 16 hereof.

     D.   Lease Contains All Terms

          All of the representations and obligations of the parties are
          contained herein and no modification, waiver or amendment of this
          Lease or of any of its conditions or provisions shall be binding upon
          a party unless in writing signed by such party.

     E.   Delivery for Examination

          Submission of the form of the Lease for examination shall not bind
          Landlord in any manner, and no Lease or obligations of the Landlord
          shall arise until this instrument is signed by both Landlord and
          Tenant and delivery is made to each.

     F.   No Air Rights

          No rights to any view or to light or air over any property, whether
          belonging to Landlord or any other person, are granted to Tenant by
          this Lease.

     G.   Modification of Lease

          If any tender, purchaser or ground lessor requires, as a condition
          to its lending funds or purchasing an interest in the Land, that
          certain modifications be made to this Lease, which modifications will
          not require Tenant to pay any additional amounts or otherwise change
          materially the rights or obligations of Tenant hereunder, Tenant
          shall, upon Landlord's request, execute appropriate instruments
          effecting such modifications.

     H.   Substitution of Premises

          At any time hereafter, Landlord may (upon thirty (30) days prior
          notice) substitute for the Premises other premises in the Building or
          the Additional Buildings (hereinafter referred to as the "New
          Premises") provided that the New Premises shall be similar to the
          Premises in area and usable for Tenant's purpose. If Tenant is already
          in occupancy of the Premises, then Landlord shall also pay the
          reasonable expenses of Tenant's moving from the Premises to the New
          Premises and for improving the New Premises so that they are
          substantially similar to the Premises. Such move shall be made during
          evenings, weekends or otherwise so as to incur the least inconvenience
          to Tenant.

     I.   Transfer of Landlord's Interest

          Tenant acknowledges that Landlord has the right to transfer its
          interest in the Land and Building and in this Lease, and Tenant agrees
          that in the event of any such transfer Landlord shall automatically be
          released from all liability under this Lease relating to periods after
          the date of such transfer and Tenant agrees to look solely to such
          transferee for the performance of Landlord's obligations hereunder
          relating to periods after the date of such transfer.

     J.   Prohibition Against Recording

          Neither this Lease, nor any memorandum, affidavit or other writing
          with respect thereto, shall be recorded by Tenant or by anyone acting
          through, under or on behalf of Tenant, and the recording thereof in
          violation of this provision shall make this Lease voidable at
          Landlord's election.

     L.   Only Landlord/Tenant Relationship

          Nothing contained in this Lease shall be deemed or construed by the
          parties hereto or by any third party to create the relationship of
          principal and agent, partnership, joint venture or any association
          between Landlord and Tenant, it being expressly understood and agreed
          that neither the method of computation of Rent nor any other
          provisions contained in this Lease nor any act of the parties hereto
          shall be deemed to create any relationship between Landlord and Tenant
          other than the relationship of landlord and tenant.

     M.   Bills

          If Tenant falls to give Landlord specific written notice of its
          objections within thirty (30) days after receipt of any bill or
          invoice hereunder, such bill or invoice shall be deemed true and
          correct and Tenant may not thereafter question the validity of such
          bill or invoice or the underlying information or computations used to
          determine the amount thereof.

     N.   Severability

          If any provision of this Lease shall be declared to be void or
          unenforceable by a final judicial or administrative order and if, in
          Landlord's judgment, such provision was not a material consideration
          for Landlord's execution of this Lease, the Lease shall continue in
          full force and effect, except that the void or unenforceable provision
          shall be deemed to be deleted from this Lease. If such provision was a
          material consideration, Landlord may terminate this Lease on 30 days
          prior written notice to Tenant.

     O.   Jury Trial

          It is the intent of the parties that this Lease be construed as if
          the covenants herein between Landlord and Tenant are independent and

increased to include the amount of such excess costs plus interest on such
amount at the rate of eleven percent (11%) per annum. If the Estimated Work Cost
is greater than the sum of Landlord's Allowance and the Amortized Amount, then
Tenant, at Tenant's option, may elect to eliminate one or more items shown on
the Preliminary Plans so as to reduce the Estimated Work Cost. If Tenant does
not so elect to eliminate one or more items shown on the Preliminary Plans, or
does so elect but the Estimated Work Cost after accounting for the eliminated
items is still greater than the sum of Landlord's Allowance and the Amortized
Amount, then Tenant shall forthwith deposit with Landlord an amount (the
"Construction Deposit") equal to one-half of the difference between (a) the sum
of Landlord's Allowance and the Amortized Amount and (b) the Estimated Work Cost
(as the same may have been revised), whereupon Landlord shall proceed in
accordance with paragraph 5 below.

          5. Construction of Tenant Improvements. Landlord shall cause its
architect and engineer to prepare construction drawings and specifications for
the Tenant Improvements based strictly on the Preliminary Plans and shall cause
the Tenant Improvements to be constructed or installed in the Premises in
accordance with such construction drawings; provided, however, that Landlord's
total cost of preparing such construction drawings and constructing and
installing the Tenant Improvements in the Premises shall not exceed the
Landlord's Allowance. Prior to the commencement of construction, Tenant shall be
given an opportunity to review the Construction drawings to confirm that they
conform to the Preliminary Plans. Upon substantial completion of the
construction and installation of the Tenant Improvements and prior to Tenant's
occupancy of the Premises, Tenant shall pay to Landlord the amount, if any, by
which the actual cost of preparing the construction drawings for the Tenant
Improvements and constructing and installing the Tenant Improvements in the
Premises exceeds the sum of the Landlord's Allowance and the Construction
Deposit.

          6. Additional Tenant Work. If Tenant desires any work in addition to
the Base Building Improvements and the Tenant Improvements to be performed In
the Premises (the "Additional Tenant Work"), Tenant, at Tenant's expense, shall
cause plans and specifications for such work to be prepared either by arranging
therefor with Landlord's architect or engineer or with consultants of Tenant's
own selection. All plans and specifications for Additional Tenant Work shall be
subject to review by Landlord to insure that the Additional Tenant Work is
compatible with all other construction, as well as the electrical and mechanical
systems, within the Building, and that it complies with all

                                      C-2
<PAGE>

applicable codes, laws, rules and regulations. Landlord's approval of Tenant's
plans and specifications for any Additional Tenant Work shall not be arbitrarily
withheld. If Landlord should approve Tenant's plans and specifications for any
Additional Tenant Work, Landlord shall, subject to the following terms and
conditions, grant to Tenant and Tenant's agents, a license to enter the Premises
prior to the Commencement Date in order that Tenant may perform or cause to be
performed the Additional Tenant Work in accordance with the plans and
specifications therefor previously approved by Landlord:


          (a) Tenant shall give Landlord not less than five (5) days' prior
     written notice of the request to have such access to the Premises, which
     notice must contain or be accompanied by: (i) a description and schedule
     for the work to be performed by those persons and entities for whom and
     which such early access is being requested; (ii) the names and addresses of
     all contractors, subcontractors and material suppliers for whom and which
     such access is being requested; (iii) the approximate number of
     individuals, itemized by trade, who shall be present in the Premises; (iv)
     copies of all contracts pertaining to the performance of the work for which
     such early access is being requested; (v) copies of all licenses and
     permits required in connection with the performance of the work for which
     such access is being requested; (vi) certificates of insurance and
     instruments of indemnification against all claims, costs, expenses, damages
     suits, fines, penalties, actions, causes of action and liabilities which
     may arise in connection with such work; and (vii) assurances of the
     availability of funds sufficient to pay for all such work, if such
     assurances are requested by Landlord. Each of the foregoing shall be
     subject to Landlord's approval, which approval shall not be arbitrarily
     withheld.

          (b) Such early access is subject to scheduling by Landlord.


          (c) Tenant's agents, contractors, workers, mechanics, suppliers and
     invitees must work in harmony and not interfere with Landlord and
     Landlord's agents in doing work in the Premises and in other premises and
     common areas of the Building or the general operation of the Building. If
     at any time such entry shall cause or threaten to cause disharmony or
     interference, including labor disharmony, Landlord may withdraw its license
     upon twenty-four (24) hours prior written notice to Tenant.


          (d) In the event that Landlord's work in the Premises and Tenant's
     work in the Premises (pursuant to the license granted herein) progresses
     simultaneously, Landlord shall not be liable for any injury to person or
     damage to property of Tenant, or of Tenant's employees, licensees or
     invitees, from any cause whatsoever occurring upon or about the Premises,
     and Tenant shall indemnify and save Landlord harmless from any and all
     liability and claims arising out of or connected with any such injury or
     damage.


          (e) Tenant agrees that it is liable to Landlord for any damage to the
     Premises or any portion of the work in the Premises caused by Tenant or any
     of Tenant's employees, agents, contractors, workers or suppliers.

          7. Tenant's Delay. As provided in Section 5C of the Lease, the Term of
the Lease (and therefore Tenant's obligation for the payment of Rent) shall not
commence until Landlord has substantially completed all work to be performed by
Landlord as set forth in paragraphs 2 and 5 above; provided, however, that if
Landlord is delayed in substantially completing such work as a result of:

                                      C-3
<PAGE>

               (a) Tenant's failure to furnish information in accordance with
     paragraph 3;

               (b) Tenant's request for materials or installations as a part of
     the Tenant Improvements that are other than Landlord's Building standard
     materials or installations;

               (c) Tenant's changes in any drawings, plans or specifications;

               (d) The performance of any Additional Tenant Work or any failure
     to complete or delay in completion of such work; or delay in (d) The
     performance of any Additional Tenant Work or any failure to complete or
     completion of such work; or

          (e) Any other act or omission of Tenant (all of which shall be deemed
     to be delays caused by Tenant),


     then the Commencement Date shall only be extended pursuant to Section 5C(1)
     of the Lease until the date on which Landlord would have substantially
     completed the performance of such work but for such delays. Postponement of
     the commencement of the Term shall be in full settlement of all claims that
     Tenant might otherwise have against Landlord by reason of the Premises not
     being ready for occupancy by Tenant as of the originally scheduled
     Commencement Date set forth in Section 1A(1) of the Lease.

          8. General. All drawings, space plans, plans and specifications for
any improvements or installations in the Premises are expressly subject to
Landlord's prior written approval. Any approval by Landlord or Landlord's
architects or engineers of any of Tenant's drawings, plans or specifications
which are prepared in connection with construction of improvements in the
Premises shall not in any way bind Landlord or constitute a representation or
warranty of Landlord as to the adequacy or sufficiency of such drawings, plans
or specifications, or the improvement to which they relate, for any use, purpose
or condition, but this approval shall merely be the consent of Landlord to
Tenant's construction of improvements in the Premises in accordance with such
drawings, plans or specifications. Failure by Tenant to pay any amounts due
hereunder shall have the same effect under the Lease as the failure to pay Rent,
and this failure or the failure by Tenant to perform any of its other
obligations hereunder shall constitute an Event of Default under Section 24(A)
of the Lease, entitling Landlord to all of its remedies under the Lease as well
as all remedies otherwise available to Landlord.

of the Complex for the parking of vehicles at the rate of Thirty and No/100
Dollars ($30.00) per space per month during the first Calendar Year of the
initial Term of this Lease, and thereafter, commencing on the first day of the
Calendar Year immediately following the Calendar Year in which Tenant's
obligation to pay monthly rent for such unassigned parking spaces in the parking
garage of the Complex begins and on the first day of each Calendar Year
thereafter during the initial Term of this Lease, such monthly rent for each
unassigned parking spaces shall increase by five percent (5%) over the monthly
rent payable for such parking spaces during the preceding Calendar Year. All

directions. If for any reason Landlord fails or is unable to provide all or any
portion of the above-described parking spaces to Tenant or Tenant is not
permitted to utilize all or any portion of such parking spaces at any time
during the Term of this Lease, such fact shall not be a default by Landlord as
to permit Tenant to terminate this Lease, either in whole or in part, but
Tenant's obligation to pay rental for any parking space which is not provided by
Landlord shall be abated for so long as Tenant does not have the use of such
parking space and this abatement shall be in full settlement of all claims that
Tenant might otherwise have against Landlord by reason of Landlord's failure or
inability to provide Tenant with such parking space. Except for those terms
specifically defined in this Exhibit, all initially capitalized terms herein
shall have the meanings set forth for such terms in the Lease to which this
Exhibit is attached.

                                OPTION TO EXTEND

     Tenant, at its option, shall have the right to extend (the "Option to
Extend") the term of the Lease for the entire Premises for an additional five
(5) years (the "Extended Term") by delivering written notice to Landlord at
least three (3) months before the expiration of the Term of the Lease, provided
that at the time said notice is so delivered and on the commencement of the
Extended Term, no event of default by Tenant as defined in the Lease is in
existence, and provided further that Tenant furnishes current financial
statements to Landlord and that no material adverse change in the financial
condition of Tenant has occurred since the financial statements last delivered
by Tenant to Landlord. Subject to the conditions set forth in the preceding
sentence, the Lease shall be extended by written amendment, duly executed by
Landlord and Tenant. The Extended Term shall commence the day following the
Termination Date of the Term, expire the day preceding the annual anniversary of
such date five (5) years thereafter and be upon the same terms, covenants and
conditions as provided in the Lease for the Term, except that Base Rent and
charges for the parking of vehicles in the Complex payable during the Extended
Term shall be at the rate then being quoted by Landlord for comparable space in
the Building at the commencement of the Extended Term, which new Base Rent and
parking charges shall be designated by Landlord and shall be increased,
adjusted, or augmented as provided in and under the Lease, unless a different
method of increase, adjustment, or augmentation is then prevailing for leases in
the Building, in which event the different method shall be used. Notwithstanding
the foregoing, Base Rent and parking charges during the Extended Term shall in
no event be less than the Base Rent and parking charges payable during the last
year of the initial Term of the Lease. Payment of Additional Rent and all other
charges required to be made by Tenant as provided in this and any other Rider
attached to the Lease for the Term shall continue to be made during the Extended
Term. Any termination of the Lease during the Term shall terminate the Option to
Extend. Any assignment of the Lease or subletting of all or a part of the
Premises by Tenant shall terminate the Option to Extend.

          The Effective Date shall be the date on which Landlord obtains

              FOURTH AMENDMENT TO METROPOINT BUILDING OFFICE LEASE
              ----------------------------------------------------


     THIS FOURTH AMENDMENT TO METROPOINT BUILDING OFFICE LEASE (this
"Amendment") is entered into for reference purposes only as of this 11th day of
 ---------
July, 1997, between MGA REAL ESTATE ASSOCIATES, LLLP, a Colorado registered
limited liability limited partnership, successor in interest to HMS Office, L.P.
("Landlord") and TANNING TECHNOLOGY CORPORATION, a Delaware corporation
  --------
("Tenant").
  ------

                                   RECITALS:
                                   --------

     A.  On January 31, 1995, Landlord and Tenant entered into that certain
Lease Agreement, which Lease Agreement has been previously amended by a First
Lease Amendment dated September 15, 1995, by a Second Lease Amendment dated
March 6, 1996 and by a Third Lease Amendment dated November 27, 1996 (the
"Lease").
 -----

     B.  Landlord and Tenant desire to further amend the Lease in the manner and
form hereinafter set forth.

     NOW, THEREFORE, in consideration of the covenants and conditions contained
herein and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, Landlord and Tenant agree to amend
the Lease as follows:

     1.  The Leased Premises, currently consisting of approximately 16,010
rentable square feet (consisting of 7,653 rentable square feet located on the
third floor of the Building and 8,357 rentable square feet located on the sixth
floor of the Building (the "Original Premises"), shall be expanded to include
                            -----------------
7,588 additional rentable square feet located on the eighth floor and known as
Suite 820 (the "Expansion Premises"), as outlined on the diagram attached hereto
                ------------------
as Exhibit A and incorporated herein by this reference.  As of the date
   ---------
specified in paragraph 2 below, any reference to the "Leased Premises" in the
                                                      ---------------
Lease shall include the Expansion Premises, and Tenant's occupancy thereof is
subject to all of the terms of the Lease, except as otherwise specifically
herein provided.

     2.  The term of the Lease with respect to the Expansion Premises shall
commence on the later to occur of August 1, 1997 or upon the issuance of a
certificate of occupancy with respect to the Expansion Premises (the
"Commencement Date") and shall terminate April 9, 2000, subject to Tenant's
- ------------------
option to extend the term of the lease as set forth in the Lease.

     3.  Monthly Base Rent for the Expansion Premises shall be as follows:
<PAGE>

         Date                        Monthly                Annual
- -----------------------------   ---------------------  --------------------
Commencement Date - 4/9/2000       $15,176.00            $182,112.00


     Base Rent is payable in the manner and place set forth in the Lease.

     4.  Paragraphs l.A(3), l.C(8) and 4 of the Lease shall not be applicable to
the Expansion Premises; provided, however, commencing on the Commencement Date,
Tenant will pay additional rent attributable to the Expansion Premises in
accordance with Exhibit C attached hereto.
                ---------

     5.  As of the Effective Date, Tenant's pro rata share with respect to the
Expansion Premises shall be as set forth in Exhibit C.
                                            ---------

     6.  Landlord agrees to perform its obligations with respect to the
Expansion Premises as set forth in Exhibit B attached hereto.  Other than as set
                                   ---------
forth therein, Landlord is not obligated to make any improvements to the
Expansion Premises, and Tenant accepts the Expansion Premises in its "as is"
condition for the Term.

     7.  So long as Tenant is not in default of any provision of the Lease, as
amended hereby, Landlord will make available the following number of additional
non-assigned parking spaces in or about the parking garage and surface lot with
respect to the Expansion Premises (the "Parking Areas"):
                                        -------------

     14 non-reserved parking garage spaces
     9 surface lot spaces

Such additional parking spaces utilized by Tenant during the term of the Lease
shall be at the market rate (currently $35.00 per month per space for non-
reserved spaces in the garage and no charge for surface lot spaces) charged for
such spaces from time to time ("Parking Rate"), and Tenant shall pay the Parking
                                ------------
Rate for all such additional spaces taken.  Tenant will receive one monthly bill
for all additional spaces taken and Tenant is to pay for all additional spaces
taken at the same time Base Rent is due.  Notwithstanding the above, the right
granted to Tenant to use such spaces is a license only and Landlord's inability
to make such spaces available at any time for reasons beyond Landlord's
reasonable control is not a material breach by Landlord of its obligations
hereunder and Tenant has no rights to use the Parking Areas except as provided
in this paragraph.  The abatement of Tenant's obligation to pay for unavailable
spaces during any period of unavailability constitutes Tenant's sole remedy.  If
Tenant fails to timely pay a parking bill, Landlord, at Landlord's option, may,
in addition to Landlord's other remedies set forth in the Lease, revoke Tenant's
license to use the additional parking spaces specified in this paragraph 7.  All
vehicles parked in the Parking Areas and the personal property therein shall be
at the sole risk of Tenant, Tenant's Agents and the users of such spaces

                                       2
<PAGE>

and Landlord shall have no liability for loss or damage thereto for whatever
cause. Landlord reserves the right to designate the location of parking stalls
within the Parking Areas that are available for Tenant's use and to change such
designation from time to time.

     8.  Tenant represents and warrants to Landlord that it has not engaged any
broker in connection with the negotiation and/or execution of this Amendment,
except for Andrew J.  Clark ("Clark").  Tenant has no knowledge of any other
                              -----
brokers' involvement in this transaction, except Vector Property Services, LLC
("Vector"), which has acted as Landlord's leasing agent.  Tenant will indemnify
  ------
Landlord and Vector against any claim or expense (including, without limitation,
attorneys' fees) paid or incurred by Landlord or Vector, respectively, as a
result of any claim for commissions or fees by any broker, finder, or agent,
whether or not meritorious, employed by Tenant or claiming by, through or under
Tenant, except for the commission that Vector has agreed to pay Clark pursuant
to a separate agreement.  Tenant and Landlord acknowledge that the other is not
liable for any representations by Vector regarding the Premises, Building or
this Amendment.

     9.  The Lease as modified herein remains in full force and effect and is
ratified by Landlord and Tenant.  In the event of any conflict between the Lease
and this Amendment, the terms and conditions of this Amendment shall control.
Capitalized terms not defined herein shall have the same meaning as set forth in
the Lease.

     10.  This Amendment is binding upon and inures to the benefit of the
parties hereto and their heirs, personal representatives, successors and
assigns.  Except as expressly provided herein, or as previously approved and
allowed by Landlord, Tenant has not assigned or transferred any interest in the
Lease and has full power and authority to execute this Amendment.  Tenant has no
known claims of any kind or nature against Landlord arising from or under the
Lease and there are no agreements between Landlord and Tenant other than the
Lease, as amended hereby.

     11.  Time is of the essence herein and, unless waived by Landlord, which it
shall have the right, but not the obligation, to so do.

     12.  This Amendment shall be governed by an construed in accordance with
the laws of the State of Colorado.

                                       3

     Re:  Premises:  Approximately 7,588 rentable square feet of space on the
                     eighth floor (the "Expansion Premises")

Gentlemen:

     Concurrently herewith, you as Tenant, and the undersigned, as Landlord,
have executed a Lease (the "Lease") covering the Expansion Premises (the
provisions of said Lease are herein incorporated by reference as if fully set
forth herein).  In consideration of the execution of said Lease, Tenant and
Landlord mutually agree as follows:

     1.  Tenant and Landlord's representative have approved the attached space
plan by Gensler Architects, dated June 9, 1997 for the Expansion Premises.
Neither Landlord's use or approval of any plans prepared by Tenant for the
preparation of the architectural, mechanical and electrical drawings (the
"Working Drawings") nor the fact that they have been prepared by Landlord's
architect shall create a responsibility or liability on the part of Landlord for
their completeness, design sufficiency, or compliance with any laws, rules and
regulations of governmental agencies or authorities now in effect or which may
hereafter be in effect.

     2.  Landlord's contractor shall perform all work for the Expansion Premises
in a good and workmanlike manner and substantially in accordance with mutually
acceptable Working Drawings (to be prepared from the attached space plan within
a reasonable period of time following mutual execution of this Lease, not to
exceed thirty (30) days) at Landlord's cost and expense, not to exceed Eight
Dollars ($8.00) per rentable square foot of the Expansion Premises.  Such Eight
Dollar ($8.00) allowance shall cover all costs related to the Expansion
Premises, including, but not limited to, design fees, costs of preparation of
the attached space plan and Working Drawings, construction management fees, and
costs of materials and construction.  Any costs in excess of the above-
referenced allowance (the "Excess Costs") will

                                      B-1
<PAGE>

be at Tenant's sole cost and expense and will be paid promptly by Tenant upon
receipt of billing therefor which may be prior to Landlord's commencement of the
work described herein. If any such Excess Costs paid by Tenant exceed the actual
costs incurred by Landlord, Landlord agrees to reimburse Tenant the amount of
the Excess Costs paid by Tenant over the actual costs within thirty (30) days
following Landlord's receipt of final invoices with respect to the work. Other
than as set forth herein, Landlord shall have no obligations for the completion
or remodeling of the Expansion Premises and Tenant shall accept the Expansion
Premises in their "as is" condition on the date the Initial Term commences.

     3.  Changes to the final approved Working Drawings may be made only by
written direction to Landlord by Tenant.  All costs incurred by such changes,
including costs of the revisions in Working Drawings and costs of construction
and materials, and reimbursables necessitated by such changes, shall be paid for
in full by Tenant prior to the commencement of the work by Landlord.  If any
such costs paid by Tenant exceed the actual costs incurred by Landlord, Landlord
agrees to reimburse such excess to Tenant in the manner set forth in paragraph 2
above.

     4.  Notwithstanding any provisions of the Lease to the contrary, the
Commencement Date and Tenant's rental obligations will not be delayed or
extended by any delay (i) in the preparation, finalization or approval of the
Working Drawings caused by Tenant, its agents or employees; (ii) caused by
modifications, revisions and changes to the Working Drawings due to changes
requested by Tenant, its agents or employees; (iii) in the delivery or
installation of any special or non-standard building items specified by Tenant;
or (iv) of any kind or nature in the completion of the Expansion Premises caused
by Tenant, its agents or employees (collectively, "Tenant Delay").

                               OPERATING EXPENSES
                               ------------------

     1.  Definitions.  The additional terms below have the following meanings:
         -----------

          (1) "Base Operating Expenses" means an amount equal to the Operating
Expenses for the calendar year 1997 ("Base Year"), as determined by Landlord in
accordance with this Exhibit C, except that for purposes of calculating Base
Operating Expenses hereunder, the Taxes for the Base Year (the "Tax Base") shall
be deemed to be $2.09 per rentable square foot (without further adjustment under
this Exhibit for actual Taxes for the Base Year, Building occupancy, or status
of completion).  Tenant acknowledges Landlord has not made any representations
or warranties that the Base Operating Expenses will equal any specified amounts
(any estimates provided by Landlord are non-binding estimates only).

          (2) "Landlord's Accountants" means that individual or firm employed by
Landlord from time to time to keep the books and records for the Building
Complex, and/or to prepare the federal and state income tax returns for Landlord
with respect to the Building Complex, which books and records shall be certified
to by a representative of Landlord.  All determinations made hereunder shall be
made by Landlord's Accountants unless otherwise stated.

          (3) "Rentable Area" means 263,719 rentable square feet of space.  If
there is a significant change in the aggregate Rentable Area as a result of an
addition, partial destruction, modification or increase in the Rentable Area on
a permanent basis or, if Landlord remeasures the Building and a change in
Rentable Area occurs, Landlord's Accountants shall make such adjustments in the
computations as are necessary to provide for such change.

          (4) "Tenant's Pro Rata Share" with respect to the Expansion Premises
means 2.8773% and with respect to the entire Leased Premises (including the
Expansion Premises) means 8.9482%.  If Tenant, at any time during the Term,
leases additional space in the Building or if the Rentable Area is adjusted,
Tenant's Pro Rata Share shall be recomputed by dividing the total rentable
square footage of space then leased by Tenant (including any additional space)
by the Rentable Area and the resulting figure shall become Tenant's Pro Rata
Share.

          (5) "Operating Expense Year" means each calendar year during the Term,
except that the first Operating Expense Year begins on the Commencement Date and
ends on December 31 of such year and the last Operating Expense Year begins on
January 1 of the calendar year in which this Lease expires or is terminated and
ends on

                                      C-1
<PAGE>

the date of such expiration or termination. If an Operating Expense Year is less
than twelve (12) months, Operating Expenses for such year shall be prorated.

          (6) "Operating Expenses" means all operating expenses of any kind or
nature which are in Landlord's reasonable judgment necessary, appropriate, or
customarily incurred in connection with the operation and maintenance of the
Building Complex.  Operating Expenses include:

               (a) All real property taxes and assessments levied against the
     Building Complex by any governmental or quasi-governmental authority,
     including taxes, assessments, surcharges, or service or other fees of a
     nature not presently in effect which are hereafter levied on the Building
     Complex as a result of the use, ownership or operation of the Building
     Complex or for any other reason, whether in lieu of or in addition to, any
     current real estate taxes and assessments.  However, any taxes which are
     levied on the rent of the Building Complex will be determined as if the
     Building Complex were Landlord's only real property.  In no event do taxes
     and assessments include any federal or state income taxes levied or
     assessed on Landlord.  Expenses for tax consultants to contest taxes or
     assessments are also included as Operating Expenses (all of the foregoing
     are collectively referred to herein as "Taxes").  Taxes also include
     special assessments, license taxes, business license fees, business license
     taxes, commercial rental taxes, levies, charges, penalties or taxes,
     imposed by any authority against the Premises, Building Complex or any
     legal or equitable interest of Landlord.  Special assessments are deemed
     payable in such number of installments permitted by law, whether or not
     actually so paid, and include any applicable interest on such installments.
     Taxes (other than special assessments) are computed on an accrual basis
     based on the year in which they are levied, even though not paid until the
     following Operating Expense Year;

               (b) Costs of supplies, including costs of relamping and replacing
     ballasts in all Building standard tenant lighting;

               (c) Costs of energy for the Building Complex, including costs of
     propane, butane, natural gas, steam, electricity, solar energy and fuel
     oils, coal or any other energy sources;

               (d) Costs of water and sanitary and storm drainage services;

                                      C-2
<PAGE>

               (e) Costs of janitorial and security services;

               (f) Costs of general maintenance, repairs, and replacements
     including costs under HVAC and other mechanical maintenance contracts; and
     repairs and replacements of equipment used in maintenance and repair work;

               (g) Costs of maintenance, repair and replacement of landscaping;

               (h) Insurance premiums for the Building Complex, including all-
     risk or multi-peril coverage, together with loss of rent endorsement; the
     part of any claim paid under the deductible portion of any insurance policy
     carried by Landlord; public liability insurance; and any other insurance
     carried by Landlord on any component parts of the Building Complex;

               (i) All labor costs, including wages, costs of workers'
     compensation insurance, payroll taxes, fringe benefits, including pension,
     profit-sharing and health, and legal fees and other costs incurred in
     resolving any labor dispute;

               (j) Professional building management fees, costs and expenses,
     including costs of office space and storage space required by management
     for performance of its services;

               (k) Legal, accounting, inspection, and other consulting fees
     (including fees for consultants for services designed to produce a
     reduction in Operating Expenses or improve the operation, maintenance or
     state of repair of the Building Complex;

               (1) Costs of capital improvements and structural repairs and
     replacements to the Building Complex to conform to changes subsequent to
     the date of issuance of the shell and core certificate of occupancy for the
     Building in any Applicable Laws (herein "Required Capital Improvements");
     and the costs of any capital improvements and structural repairs and
     replacements designed primarily to reduce Operating Expense (herein "Cost
     Savings Improvements").  Expenditures for Required Capital Improvements and
     Cost Savings Improvements will be amortized at a market rate of interest
     over the useful life of such capital improvement (as determined by
     Landlord's Accountants); however, the amortized amount of any Cost Savings
     Improvement in any year

                                      C-3
<PAGE>

     will be equal to the estimated resulting reduction in Operating Expenses;
     and

               (m)  Costs incurred for Landlord's Accountants including costs of
     any experts and consultants engaged to assist in making the computations;

     "Operating Expenses" do not include:
                             ---

                i)   Costs of work, including painting and decorating, which
     Landlord performs for any tenant other than work of a kind and scope which
     Landlord is obligated to furnish to all tenants whose leases contain a
     rental adjustment provision similar to this one;

               ii)   Costs of repairs or other work occasioned by fire,
     windstorm or other insured casualty to the extent of insurance proceeds
     received;

              iii)   Leasing commissions, advertising expenses, and other costs
     incurred in leasing space in the Building;

               iv)   Costs of repairs or rebuilding necessitated by
     condemnation;

                v)   Interest on borrowed money or debt amortization, except as
     specifically set forth above; or

               vi)   Depreciation on the Building Complex.

If any lease entered into by Landlord with any tenant in the Building is on a
so-called "net" basis, or provides for a separate basis of computation for any
Operating Expenses with respect to its leased premises, Landlord's Accountants
may modify the computation of Base Operating Expenses, Rentable Area, and
Operating Expenses for a particular Operating Expense Year to eliminate or
modify any expenses which are paid for in whole or in part by such tenant.  If
the Rentable Area is not fully occupied during any particular Operating Expense
Year, Landlord's Accountants may adjust those Operating Expenses which are
affected by occupancy for the particular Operating Expense Year to reflect 100%
occupancy.  Furthermore, in making any computations contemplated hereby,
Landlord's Accountants may make such other modifications to the computations as
are required in their judgment to achieve the intention of the parties hereto.

     2.  Additional Payment.  If any increase occurs in Operating Expenses for
         ------------------
any Operating Expense Year during the Term in excess of the Base Operating
Expenses, Tenant shall pay Landlord Tenant's Pro Rata Share of the amount of
such increase (less Estimated Payments, if any, previously made by Tenant for
such year).

     3.  Estimated Payments.  During each Operating Expense Year beginning with
         ------------------
the first month of the second Operating Expense Year and continuing each month
thereafter throughout the Term, Tenant shall pay Landlord, at the same time as
Base Rent is paid, an amount equal to 1/12 of Landlord's estimate of Tenant's
Pro Rata Share of any projected increases in Operating Expenses for the
particular Operating Expense Year in excess of Base Operating Expenses
("Estimated Payment").

     4.  Annual Adjustments.
         ------------------

               (a) Following the end of each Operating Expense Year, including
     the first Operating Expense Year, Landlord shall submit to Tenant a
     statement setting forth the exact amount of Tenant's Pro Rata Share of the
     increase, if any, of the Operating Expenses for the Operating Expense Year
     just completed over the Base Operating Expenses.  Beginning with the
     statement for the second Operating Expense Year, each statement shall set
     forth the difference, if any, between Tenant's actual Pro Rata Share of the
     increase in Operating Expenses for the Operating Expense Year just
     completed and the estimated amount for such Operating Expense Year.  Each
     statement shall also set forth the projected increase, if any, in Operating
     Expenses for the new Operating Expense Year above or below the Rent paid by
     Tenant for the immediately preceding Operating Expense Year.  The effect of
     this provision is that the only increases to be borne by Tenant for the
     first Operating Expense Year will be the positive difference (if any)
     between the actual Taxes for the first Operating Expense Year and the Tax
     Base.

               (b) To the extent that Tenant's Pro Rata Share of the increase in
     Operating Expenses for the period covered by a statement is different from
     the Estimated Payment during the Operating Expense Year just completed,
     Tenant shall pay Landlord the difference within 30 days following receipt
     by Tenant of the statement or receive a credit against the next due Rent,
     as the case may be.  Until Tenant receives a statement, Tenant's Estimated
     Payment for the new Operating Expense Year shall continue to be paid at the
     prior Estimated Payment, but Tenant shall commence payment of Rent based on
     the new Estimated Payment beginning on

                                      C-5
<PAGE>

     the first day of the month following the month in which Tenant receives the
     statement. Tenant shall also pay Landlord or deduct from the Rent, as the
     case may be, on the date required for the first payment, as adjusted, the
     difference, if any, between the Estimated Payment for the new Operating
     Expense Year set forth in the statement and the Estimated Payment actually
     paid during the new Operating Expense Year. If, during any Operating
     Expense Year, there is a change in the information on which Tenant is then
     making its Estimated Payments so that the prior estimate is no longer
     accurate, Landlord may revise the estimate and there shall be such
     adjustments made in the monthly Rent on the first day of the month
     following notice to Tenant as shall be necessary by either increasing or
     decreasing, as the case may be, the amount of monthly Rent then being paid
     by Tenant for the balance of the Operating Expense Year.

     5.  Miscellaneous.  In no event will any decrease in Rent pursuant to any
         -------------
provision hereof result in a reduction of Rent below the Base Rent.  Delay by
Landlord in submitting any statement for any Operating Expense Year does not
affect the provisions of this Section or constitute a waiver of Landlord's
rights for such Operating Expense Year or any subsequent Operating Expense
Years.

     6.  Dispute.  If Tenant disputes an adjustment submitted by Landlord or a
         -------
proposed increase or decrease in the Estimated Payment, Tenant shall give
Landlord notice of such dispute within 30 days after Tenant's receipt of the
adjustment.  If Tenant does not give Landlord timely notice, Tenant waives its
right to dispute the particular adjustment.  If Tenant timely objects, Tenant
may engage its own certified public accountants ("Tenant's Accountants") to
verify the accuracy of the statement complained of or the reasonableness of the
estimated increase or decrease.  If Tenant's Accountants determine that an error
has been made, Landlord's Accountants and Tenant's Accountants shall endeavor to
agree upon the matter, failing which such matter shall be submitted to an
independent certified public accountant selected by Landlord, with Tenant's
reasonable approval, for a determination which will be conclusive and binding
upon Landlord and Tenant.  All costs incurred by Tenant for Tenant's Accountants
shall be paid for by Tenant unless Tenant's Accountants disclose an error,
acknowledged by Landlord's Accountants (or found to have occurred through the
above independent determination), of more than 25% in the computation of the
total amount of Operating Expenses, in which event Landlord shall pay the
reasonable costs incurred by Tenant to obtain such audit.  Notwithstanding the
pendency of any dispute, Tenant shall continue to pay Landlord the amount of the
Estimated Payment or adjustment determined by Landlord's Accountants until the
adjustment has been determined to be incorrect.  If it is determined that any
portion of the Operating Expenses were not properly chargeable to Tenant, then
Landlord shall promptly credit or refund the appropriate sum to Tenant.

          Premises shall be adjusted to reflect the number of square feet of
          Rentable Area determined by such calculation.  At the request of

          known as 4600 SOUTH SYRACUSE, 4600 South Syracuse Street, Denver,
          Colorado 80237, located on the Land and in which the Premises are
          located.  The Rentable Area of the Building is approximately as stated
          above, and shall be specifically calculated by Landlord's architects
          when floor plans for the Building are complete.  Upon such
          determination by Landlord's architect, the Rentable Area of the
          Building shall be adjusted to reflect the number of square feet of
          Rentable Area determined by such calculation.

     (2)  "Building-Shared Areas" means the square footage of the areas within
          (and measured from the mid-point of the walls enclosing) the Building
          elevator machine rooms, main mechanical and electrical rooms, public
          lobbies, and other areas not leased or held for lease within the
          Building but which are necessary or desirable for the proper
          utilization of the Building or to provide customary

                                       2
<PAGE>

          services to the Building. The allocation to the Premises of the
          Building-Shared Areas shall be equal to the total Building-Shared
          Areas within the Building multiplied by a fraction, the numerator of
          which is the Usable Area of the Premises and the denominator of which
          is the Usable Area leased or held for lease for general office
          purposes in the Building.

     (3)  "Building Standard" means the items described as building standard
          finishes on Exhibit G, as such items may be revised from time-to-time

          December, which contains any part of the Term of this Lease.

     (5)  "Complex" means the Land, the Building, the parking garage, and all
          other improvements on the Land or directly benefiting the Building
          from time to time, and all additional facilities directly benefiting

          underground pedestrian tunnels and aboveground pedestrian skywalks,
          and including any variations or additions thereto, but excluding any
          additional office buildings which might be built on the Land.

     (6)  "Computed Operating Expenses" means, with respect to each Calendar
          Year during the Term, the actual Operating Expenses for said Calendar

          measured from the mid-point of the walls enclosing) public corridors,
          elevator foyers, rest rooms, mechanical rooms, janitor closets,

          use of all tenants on the floor on which the Premises are located.  In
          the case of a floor leased to more than one tenant, the allocation to
          the Premises of the Floor-Shared Areas on said floor shall be equal to
          the total Floor-Shared Areas on said floor multiplied by a fraction,
          the numerator of which is the Usable Area of the Premises located on
          said floor and the denominator of which is the Usable Area of said
          floor.

     (8)  "Land" means the real property legally described on Exhibit B.

     (9)  "Lease Year" means each twelve (12) month period beginning with the

          Landlord reserves the right at any time to make all adjustments
          provided for herein on a Calendar Year basis, with an appropriate
          proration for the Lease Years in which such conversion is made and in
          which the Term ends, and "Lease Year" as used in any portion of this
          Lease pertaining to such adjustments shall thereafter be deemed to
          refer to "Calendar Year".

     (10) "Operating Expenses" means all expenses, costs and disbursements of
          every kind and nature which Landlord shall in good faith pay or incur

          vi)  Cost of repairs and maintenance (excluding repairs and
               maintenance paid by proceeds of insurance or by Tenant or other
               third parties, and alterations attributable solely to tenants of
               the Building other than Tenant).

          vii) Amortization of the cost of capital investment items which are
               primarily for the purpose of reducing operating costs or which
               may be required by governmental authority, or to promote safety
               or to maintain the quality of the Complex.  All such costs shall
               be determined and amortized over the reasonable life or payback
               period, as Landlord may elect, of the capital investment items in
               accordance with generally accepted accounting principles,
               together with a commercially reasonable financing charge factor.
               In no event shall the amortization period extend beyond the
               reasonable life of the Building.

                                       4

          viii) All internal control audit and operating expense audit costs for
                the Complex, and a prorata allocation for the Complex of the
                costs of the off-site project accounting, senior property
                management, payroll and risk management departments of Landlord
                and/or the property manager, including personnel costs, office
                rent and other associated costs incurred in connection with such
                departments.

          ix)   Office rent (to the extent such rent does not exceed the fair
                market rental rate for the applicable space, as defined below)
                and other costs of a management office within the Complex.

          x)    Costs of operating a reception desk and /or other amenities or
                services for the general benefit of tenants of the Building that
                may be provided now or in the future.

          xi)   All Taxes (as defined below).

          xii)  A contribution (the "Management Fee Contribution") towards a
                management fee payable to the manager of the Building, said
                contribution to be equal to three percent (3%) of the Annual
                Rent (as the same may be adjusted from time to time as set forth
                above) and of Tenant's Share of Computed Operating Expenses as
                described below (but excluding the Management Fee Contribution).

          Operating Expenses shall not include any settlement, payment or
          judgment incurred by Landlord due to its willful misconduct or gross
          negligence, as established by a court of law, or the cost of any
          damage to the Complex caused directly by Landlord's willful misconduct
          or gross negligence, as established by a court of law.

     (11) "Premises" means that portion of the Building identified as such on
          Exhibit C and containing the Rentable Area set forth in Section
          1.A.(5).  The Premises do not include, and Landlord hereby excludes
          and reserves for its sole and exclusive use, any and all: janitor
          closets, stairways and stairwells; fan, mechanical, electrical,
          telephone and similar rooms; elevator, pipe and other vertical shafts,
          flues and ducts; (other than, as to all the above in this Section
          1.C.(7), those installed for or available for Tenant's exclusive use);
          all areas above the acoustical ceiling and below the finished floor
          covering installed in the Premises; and other areas not shown on
          Exhibit C as being part of the Premises.

     (12) "Rentable Area" refers to the square footage area or areas within the
          Building determined by adding the following:

          i)   the Usable Area of the area being measured;

                                       5
<PAGE>

          ii)  the portion of the Building-Shared Areas allocable to the area
               being measured; and

          iii) the portion of the Floor-Shared Areas allocable to the area
               being measured.

     (13) "Service Areas" means the square footage of the areas within (and
          measured from the mid-point of the walls enclosing) the Building
          stairs, fire towers, elevator shafts, flues, vents, stacks, pipe
          shafts, vertical ducts and other vertical penetrations.  Areas for the
          specific use of Tenant and installed at the request of Tenant such as
          special stairs or elevators are not included within the definition of
          Service Areas (i.e., such areas will be included in the Usable Area
          leased of the space being measured).

     (14) "Taxes" means all real estate and personal property taxes and
          assessments (general, special or otherwise) and license or other fees,
          levied or assessed by any federal, state, city and county or local
          government or by any other taxing district or authority upon or with
          respect to the Complex, the maintenance equipment and vehicles,
          elevators, building machinery and other personal property owned or
          leased by Landlord and used exclusively for the operation of the
          Complex (or if not used exclusively for the Complex, a prorata share
          of the same based upon the amount such personal property is used in
          connection with the operation of the Complex compared to its total
          use).  Should any governmental authority having jurisdiction over the
          Complex impose an income or franchise tax or a tax on rents in
          substitution, in whole or in part, for such real estate or personal
          property taxes or license or other fees or in lieu of any increase in
          such taxes or fees, such income, franchise or rent tax shall be deemed
          to constitute Taxes hereunder.  All references to Taxes for a
          particular year shall be deemed to refer to Taxes levied, assessed or
          otherwise imposed in such year without regard to when such Taxes are
          payable. Taxes shall also include all special taxes and special
          assessments, all of which or installments of which are required to be
          paid, or which Landlord elects to pay, during any Calendar Year.

     (15) "Tenant's Share of Computed Operating Expenses" means, with respect to
          any Calendar Year, the sum of (a) the Management Fee Contribution for
          such year, and (b) the Computed Operating Expenses for such year,
          which sum shall be (I) divided by the greater of ninety-five percent
          (95%) of the Rentable Area of office space leased or held for lease in
          the Building or the total Rentable Area of office space actually
          leased in the Building, and (II) multiplied times the number of square
          feet of Rentable Area contained within the Premises. Notwithstanding
          the foregoing provisions, Landlord shall not be entitled to collect a
          greater amount with respect to the Computed Operating Expenses for any
          calendar year during the Term than the Computed Operating Expenses
          actually paid or incurred by Landlord for that calendar year.  In
          addition, notwithstanding the foregoing provisions, during any portion
          of the Term that the Building is not fully occupied, or that the
          Building is not fully furnished with all of the services referred to
          in Section 7, the Tenant's Share of Computed Operating Expenses with
          respect to those Operating Expenses which are variable depending upon
          occupancy (such as janitorial costs) shall be equitably adjusted so as
          to attribute to Tenant its fair

                                       6
<PAGE>

          share, based on what Tenant has received, of such variable Operating
          Expenses, but shall not be adjusted with respect to any Operating
          Expenses which are not variable depending upon occupancy (such as
          landscape maintenance). If Landlord should lease any premises in the
          Building on a net lease or similar basis such that Landlord does not
          fully furnish to the tenant(s) of such premises any one or more of the
          services described in Section 7, then, with respect to those items of
          Operating Expenses that would have been incurred by Landlord had
          Landlord fully furnished all of the services described in Section 7 to
          such premises, such premises shall be deemed "unoccupied" for purposes
          of the preceding sentence.

     (16) "Term" means the term of this Lease which shall commence on the
          Commencement Date set forth in Section 1.A.(1) or the later
          Commencement Date to which such commencement may be extended pursuant
          to Section 5.C. or Exhibit D, and which shall end on the Expiration
          Date set forth in Section 1.A.(1) or the later Expiration Date to
          which such expiration may be extended pursuant to Section 5.C. or
          Exhibit D, unless terminated earlier or extended further as provided
          in this Lease.

     (17) "Usable Area" means the square footage of the areas within the
          Premises measured from the inside surface of the outer glass, finished
          column or exterior wall of the Building enclosing the Premises to the
          inside surface of the opposite outer glass, finished column or
          exterior wall, or to the mid-point of the demising walls separating
          the Premises from:

          i)    areas leased to or held for lease to other tenants;

          ii)   Building-Shared Areas;

          iii)  Floor-Shared Areas; and

          iv)   Service Areas, as the case may be. No deductions from Usable
                Area shall be made for columns or projections necessary to the
                Building.

     Certain additional defined terms are used in this Lease; such terms have
the meanings set forth in the sections of this Lease where the definitions of
such terms appear.

2.        DEMISE. In consideration of the keeping, observance and performance by
     Tenant of the provisions, conditions, terms, obligations, covenants, and
     agreements contained in this Lease and the payment by Tenant of the Rents
     herein reserved, Landlord hereby demises and leases to Tenant, and Tenant
     hereby takes from Landlord, the Premises for the Term hereof, subject to
     the provisions, covenants, agreements, obligations, terms and conditions of
     this Lease, matters of record, and existing covenants, conditions,
     restrictions, easements and encumbrances affecting the same.

     Hereinafter unless otherwise provided, "covenants" includes "agreements and
obligations" and "provisions" includes "terms."

                                       7

3.      ANNUAL RENT.

A.      Annual Rent. Commencing on the Commencement Date and thereafter during
     the Term, Tenant covenants and agrees to pay the rent described in this
     Section 3 (the "Annual Rent") in accordance with the provisions hereof.
     Annual Rent for each Lease Year shall be equal to the amount specified in
     Section 1A(2) multiplied by the number of square feet of Rentable Area of
     the Premises, and shall be payable in monthly installments pursuant to
     Section 3.B. below. Notwithstanding any provision contained elsewhere in
     this Lease to the contrary, provided that Tenant is not otherwise in
     default under the terms and provisions of this Lease, Annual Rent shall be
     abated during the first five (5) months of the Term, and Tenant shall
     commence Annual Rent payments on the date which is six (6) months from the
     Commencement Date.

B.      Terms of Payment. Annual Rent during each Lease Year shall be due and
     payable in monthly installments equal to one-twelfth of the Annual Rent for
     such Lease Year, and received by Landlord in advance on or before the first
     day of each and every month during the Term.  If the Term commences other
     than on the first day of a month or ends other than on the last day of a
     month, Annual Rent for such month shall be prorated based on the number of
     calendar days in that month.  All payments of Annual Rent and other "Rent"
     (as defined below) shall be made to Landlord at Denver Hines Development,
     LLC, at the address of the Building, or at such other place as Landlord may
     from time to time designate to Tenant in writing, without any demand,
     counterclaim, set-off or deduction whatsoever.

4.      ADDITIONAL RENT. In addition to paying the Annual Rent specified in
     Section 3 hereof, Tenant shall pay as "Additional Rent" the amounts
     described in this Section 4 as adjustments to such Annual Rent.  The (i)
     Annual Rent, the (ii) Additional Rent and (iii) all other amounts payable
     by Tenant to Landlord pursuant to this Lease are sometimes herein
     collectively referred to as the "Rent."

A.      Tenant's Share of Computed Operating Expenses. For each Calendar Year
     during the Term, prior to January 1 of each such Calendar Year (or prior to
     the commencement of the Term as to the year in which the Commencement Date
     occurs), Landlord shall provide Tenant in writing a comparison of the
     Initial Operating Expenses Basic Cost with the projected Tenant's Share of
     Computed Operating Expenses with respect to such Calendar Year, and
     thereafter Tenant shall pay an adjusted Annual Rent for such year which
     shall include an appropriate amount on account of the excess of such
     projected Tenant's Share of Computed Operating Expenses over the Initial
     Operating Expenses Basic Cost; provided, however, that Tenant shall not be
     obligated to pay any amount of such excess which is attributable to Taxes
     unless the Taxes for such Calendar Year have exceeded $2.80 per square foot
     of Rentable Area in the Building.  Landlord shall, within a period of one
     hundred fifty (150) days (or as soon thereafter as possible) after the
     close of each such Calendar Year, provide Tenant a statement of the
     Operating Expenses for such year and a calculation based thereon of
     Tenant's Share of Computed Operating Expenses for such year.  If Tenant's
     Share of Computed Operating Expenses for such year is greater than the
     projected amount theretofore paid by Tenant for such year, Tenant shall pay
     to Landlord within thirty (30) days after Tenant's receipt of the statement
     the amount of such excess.  However, if Tenant's Share of Computed
     Operating Expenses for such year is less than the projected amount
     theretofore paid by Tenant for such year, Landlord shall pay to Tenant
     within thirty (30) days after Tenant's receipt of the statement the amount
     of such overpayment.

                                       8
<PAGE>

B.      Partial Years. Tenant's obligation to pay the Additional Rent provided
     for in this Section 4 which is accrued but not paid for periods prior to
     the expiration or termination of the Term shall survive such expiration or
     termination. Should this Lease commence or terminate at any time other than
     the first day of a Calendar Year, Tenant's Share of Computed Operating
     Expenses referred to in Sections 4.A and 4.B above shall be calculated, for
     the commencement or termination year only, by the following formula:

     Days Leased X Tenant's Share of Computed Operating Expenses/ 365= Adjusted
     Tenant's Share of Computed Operating Expenses.

C.      Objections by Tenant. If Tenant is not then in default under the terms
     of this Lease and if Tenant in good faith objects to the calculation of
     Operating Expenses or Tenant's Share of Computed Operating Expenses for the
     prior year (i.e., the year covered by the statement submitted under Section
     4.A), Tenant may notify Landlord in writing of its objections at any time
     within ninety (90) days following the date the statement of Operating
     Expenses and calculation of Tenant's Share of Computed Operating Expenses
     is provided pursuant to Section 4.A. If Tenant so notifies Landlord of its
     objections, Landlord may furnish Tenant with a copy of a review or audit of
     the Operating Expenses for the prior year for the Complex as a whole,
     performed by an independent certified accounting firm (the "Complex
     Audit"), if such a Complex Audit has been performed. If Tenant has
     remaining objections after its review of the Complex Audit, if one is
     furnished, Tenant must notify Landlord in writing of its remaining
     objections at any time within sixty (60) days following the date the
     Complex Audit has been provided to Tenant. In any event, if Tenant has
     initially raised objections and Landlord has not provided a copy of the
     Complex Audit, or if Tenant raises remaining objections after it has been
     provided with a copy of the Complex Audit, and such objections are not
     resolved within sixty (60) days of Tenant's applicable notice of
     objections, then Landlord shall appoint within ninety (90) days of Tenant's
     objection letter a nationally recognized independent certified public
     accounting firm (which may be the same firm that has performed the Complex
     Audit for the Complex as a whole, if such a Complex Audit has been
     performed), to act as an expert and not an arbitrator, to review Landlord's
     books and records for the Complex relating to Operating Expenses and
     Tenant's Share of Computed Operating Expenses for compliance with this
     Lease, in which case the independent certified public account firm will be
     instructed to issue a report within sixty (60) days from engagement. The
     determination of such independent certified public accounting firm shall be
     binding on both Landlord and Tenant. The costs incurred by such independent
     certified public accounting firm in such review shall be the sole
     responsibility of Tenant and shall be paid by Tenant within thirty (30)
     days from such invoice, unless it is determined that Landlord overstated
     Tenant's Share of Computed Operating Expenses by more than three percent
     (3%) in the aggregate, in which case Landlord shall be responsible for such
     costs. If Tenant fails to object in writing to Operating Expenses or the
     calculation of Tenant's Share of Computed Operating Expenses within ninety
     (90) days following the date the statement of Operating Expenses and
     calculation of Tenant's Share of Computed Operating Expenses is provided
     under Section 4.A, or if Tenant then fails to object in writing within
     sixty (60) days after a Complex Audit, if any, is provided, then Tenant
     shall have no objection rights with respect thereto and Operating Expenses
     and Tenant's Share of Computed Operating Expenses for such year shall be
     final and not subject to audit or adjustment. Tenant understands and agrees
     that all information concerning Operating Expenses that is obtained by
     Tenant or that is provided to Tenant, including pursuant to this Section
     4.C., is confidential and proprietary information of Landlord and may not
     be disclosed to any third party by Tenant or used by Tenant for any purpose
     unrelated to this Lease. Upon request, Tenant shall execute and

                                       9
<PAGE>

     deliver a confidentiality and non-disclosure and restricted use agreement
     in favor of Landlord and its property manager in form and content
     acceptable to Landlord to confirm and implement the provisions of the
     immediately preceding sentence.

D.      No Reduction in Annual Rent. The Annual Rent stated in Section 1A(2)
     shall not be reduced if Operating Expenses for any Calendar Year are below
     the Initial Operating Expenses Basic Cost.

5.      CONSTRUCTION AND POSSESSION.

A.      Construction of Premises. Landlord will proceed to complete the Base
     Building Shell as described in Exhibit G, and the additional initial
     improvements in the Premises will be completed by Landlord in accordance
     with the Tenant Construction Agreement attached hereto as Exhibit D.
     Landlord and Tenant agree that all alterations, improvements and additions
     made to the Premises pursuant to a Tenant Construction Agreement, whether
     paid for by Landlord or Tenant, shall without compensation to Tenant become
     Landlord's property upon installation and shall remain Landlord's property
     at the expiration of the Term or sooner termination of this Lease;
     provided, however, that Tenant may remove any of such alterations,
     additions and improvements which Landlord and Tenant agree in writing may
     be removed from the Premises at the expiration of the Term or sooner
     termination of this Lease (such agreement not to be unreasonably withheld).
     Landlord and Tenant shall enter into a written agreement concerning the
     removal of any such alterations, additions or improvements prior to or at
     the time of installation thereof.

B.      Early Occupancy. Tenant has no right to enter the Premises until the
     same are tendered by Landlord unless Tenant's entry is for purposes
     relating to construction work in the Premises and is in accordance with the
     terms of a Tenant Construction Agreement. Tenant may request Landlord's
     permission to store certain items of personal property in the Premises
     immediately prior to the Commencement Date, and Landlord shall then notify
     Tenant as to whether such storage will be permitted; provided however, that
     (i) the decision as to whether such storage shall be permitted shall be
     within the sole discretion of Landlord, (ii) if Landlord allows such
     storage, it shall be only in the areas and for the time periods designated
     by Landlord, and shall not interfere in any fashion with the completion of
     the Building or the Tenant Work within the Premises, and (iii) such storage
     shall be at Tenant's sole cost and risk, and neither Landlord or its
     contractors or subcontractors, nor any of their agents, employees,
     licensees, or invitees, shall have any liability or responsibility
     whatsoever for any damages, costs, liabilities or expenses in connection
     with such stored personal property. Any occupancy of the Premises by Tenant
     for the regular conduct of Tenant's business prior to the Commencement Date
     will be permitted only with the express written consent of Landlord. If
     Tenant shall so take possession of any part of the Premises for business
     purposes prior to the Commencement Date pursuant to Landlord's prior
     written consent, all of the covenants, provisions and conditions of this
     Lease shall be binding upon the parties hereto with respect to such portion
     of the Premises in the same manner as if the Commencement Date had been
     fixed as the date when Tenant took possession and Tenant shall pay to
     Landlord Rent for the period of such occupancy prior to the scheduled
     Commencement Date at the rates set forth in Section 3 and Section 4 hereof,
     pro-rated for the portion of Premises so occupied. Under no circumstances
     shall the occurrence of any of the events referred to in this Section 5.B.
     be deemed to accelerate the Expiration Date.

                                       10
<PAGE>

C.      Failure to Complete. If Landlord fails to substantially complete its
     obligations under the Tenant Construction Agreement and tender the Premises
     to Tenant in accordance with the Tenant Construction Agreement on or before
     the date set forth therein, Landlord will not be in default or liable in
     damages to Tenant, nor will the obligations of Tenant hereunder be
     affected, provided, however, that:

        (1)     if Landlord fails to commence construction of the Building, by
                pouring the foundations therefor, on or before September 1,
                1998, then either Landlord or Tenant shall have the right to
                terminate this Lease, by written notice delivered to the other
                not more than thirty (30) days after such date;

        (2)     the Commencement Date shall automatically be extended by one day
                for each day of the period beyond the date set forth in Section
                1.A.(1) that Landlord fails to so substantially complete its
                obligations, less any portion of that period attributable to
                Tenant's delays as more particularly described in a Tenant
                Construction Agreement, and the Expiration Date shall
                automatically be extended by the same number of days that the
                Commencement Date is so extended (except that if such extension
                would result in the Expiration Date occurring on other than the
                last day of a calendar month, the Expiration Date shall be
                extended by the additional number of days required in order for
                the Expiration Date to occur on the last day of a calendar
                month); and

        (3)     if the general contractor for the Building is to perform the
                Tenant Work in the Premises under the Tenant Construction
                Agreement, then if the Base Building Shell has not been
                completed so that Landlord and such general contractor may
                commence the Tenant Work in the Premises in accordance with the
                Tenant Construction Agreement on or before September 1, 1999
                (plus any period of delay caused by Tenant as described in the
                Tenant Construction Agreement), Tenant shall have the additional
                right to terminate this Lease and all obligations and rights
                created hereby, by delivering written notice of termination to
                Landlord not more than thirty (30) days after such date;
                provided, however, that if a contractor other than the general
                contractor for the Building has been selected to perform the
                Tenant Work under the Tenant Construction Agreement, then
                Tenant's right to terminate as set forth in the first part of
                this subparagraph shall not arise unless the Base Building Shell
                has not been completed by November 1, 1999.

Upon a termination under subparagraph (2) above, each party shall, upon the
other's request, execute and deliver an agreement in recordable form containing
a release and surrender of all right, title and interest in and to this Lease;
neither Landlord nor Tenant shall have any further obligations to each other,
including without limitation, any obligations to pay for work previously
performed in the Premises; all improvements to the Premises shall become and
remain the property of Landlord; and Landlord shall refund to Tenant any sums
paid to Landlord by Tenant in connection with this Lease, including without
limitation any payments to Landlord of construction costs for the Premises.
Such postponement of the commencement of the Term and such termination and
refund right shall be in full settlement of all claims that Tenant might
otherwise have against Landlord by reason of Landlord's failure to substantially
complete its obligations under the Tenant Construction Agreement by the date set
forth in Section 1.A.(1).

                                       11

D.        Punch List. Tenant's taking possession of any portion of the Premises
     (other than for storage of personal property which may have been permitted
     by Landlord pursuant to the provisions of Section 5.B above) shall be
     conclusive evidence that such portion of the Premises was in good order and
     satisfactory condition when Tenant took possession, except as to items
     contained on a punch list to be prepared after an inspection made and
     signed by representatives of Landlord and Tenant when Tenant takes
     possession.  Landlord shall not be responsible for any items of damage
     caused by Tenant, its agents, employees, invitees, licensees, contractors,
     workmen or suppliers.  No promise of Landlord to alter, remodel or improve
     the Premises or the Building or Complex and no representation respecting
     the condition of the Premises or the Building or Complex have been made by
     Landlord to Tenant other than as may be contained in this Lease or in a
     Tenant Construction Agreement.

6.        OCCUPANCY OF PREMISES.

A.        Use. Tenant shall use and occupy the Premises only for the use
described in Section 1.A.(4) (the "Tenant's Use").

B.        Compliance. Tenant shall not use or permit the use of the Premises or
     the Complex or any part thereof for any purpose prohibited by law. Tenant
     shall, at its sole expense, comply with and conform to all of the
     requirements of all governmental authorities having jurisdiction over the
     Complex which relate in any way to the condition, use and occupancy of the
     Premises throughout the entire Term of this Lease (other than structural
     and system repairs as described in Section 7.A.(1), which are the
     responsibility of Landlord, or the repair of any latent defects in the
     initial construction of the Building or the Premises as set forth in the
     Tenant Construction Agreement, or any requirements due to the non-
     compliance of the Building or the Premises as initially constructed with
     the building codes applicable at the time of construction, which shall
     remain the responsibility of Landlord to the extent set forth in the Tenant
     Construction Agreement).

7.        SERVICES PROVIDED BY LANDLORD.

A.        Description of Standard Services. Landlord will furnish for Tenant
and the Premises, subject to the other provisions of this Section 7, the
following services:

     (1)  repair and maintenance of all structural elements of the Building,
          including the plumbing, electrical, HVAC and life safety systems
          installed in the Building as part of either the Base Building Shell or
          the Building Standard finishes as described in Exhibit G, but
          excluding any systems installed in the Premises which are over and
          above the Base Building Shell or the Building Standard systems, each
          of which shall be maintained by Tenant (or at Tenant's request, by
          Landlord, with all of the costs thereof payable by Tenant to Landlord
          upon presentation of an invoice therefor as additional Rent
          hereunder).  The cost of such repair and maintenance by Landlord of
          the structural elements of the Building shall be included in Operating
          Expenses unless otherwise provided in this Lease or unless caused by
          the act or omission of Tenant, its agents, employees, contractors,
          visitors, licensees, workmen, suppliers, or invitees, in which latter
          case such cost shall be paid by Tenant within 15 days after written
          demand therefor;

                                       12
<PAGE>

     (2)  heating, ventilating and air conditioning (heating or cooling as
          required by the seasons), without special request from Tenant, from
          7:00 a.m. to 6:00 p.m. on Monday through Friday, except holidays, at
          temperatures and in amounts as may, in the sole judgment of Landlord,
          be reasonably required for comfortable use and occupancy under normal
          business operations with "Customary Office Equipment" (as used in this
          Lease, "Customary Office Equipment" shall include personal computers,
          calculators, dictation recorders, small reproduction machines and
          similar devices and equipment but shall not include any machines,
          devices or equipment that adversely affect the temperature otherwise
          maintained in the Premises such as, e.g., data processing, computer
          (other than personal computers) or heavy-duty reproduction equipment).
          If Tenant shall require such heat, ventilation or air conditioning
          outside the hours and days specified above, Landlord will furnish the
          same for the hours specified in a request from Tenant (an "HVAC
          Request") and for this service Tenant will pay Landlord, upon receipt
          of Landlord's statement, the hourly rate reasonably determined by
          Landlord from time to time; provided, however, that Tenant shall not
          be required to pay any such charge for heating, ventilation or air
          conditioning requested by Tenant in an HVAC Request for the hours from
          8:00 a.m. to 1:00 p.m. on Saturdays (except holidays).  Any HVAC
          Request by Tenant shall be made in such a manner and at such time as
          Landlord may from time to time establish for HVAC Requests, and Tenant
          acknowledges and agrees that Landlord may require that HVAC Requests
          be made by Tenant's authorized employees by direct code or card access
          to the computer system controlling the Building's mechanical system.

     (3)  water for lavatory and toilet purposes, all water service to be
          supplied from the regular supply of water to the Building at points of
          supply provided for general use of tenants of the Building through
          fixtures installed by Landlord;

     (4)  janitorial services to the Premises on a five (5) days per week basis
          at no extra charge; provided, however, Tenant shall pay as Additional
          Rent, upon presentation of Landlord's statement, the additional cost
          for cleaning its floor coverings and other improvements which are not
          Building Standard.

     (5)  passenger elevators for access to and from the floor(s) on which the
          Premises are located, elevators within the parking garage, and freight
          elevator service by a swing cab (but only when scheduled through the
          Manager of the Building);

     (6)  toilet facilities on each of the floors occupied by Tenant (which, if
          a multi-tenant floor, shall be in common with other tenants);

     (7)  electric lighting for all public areas and special service areas of
          the Building as reasonable and standard for first-class office
          buildings, including replacement of light bulbs and tubes;

     (8)  replacement of light bulbs in those Building standard lighting
          fixtures installed in the Premises; and

     (9)  electrical current as specified on Exhibit G hereto.

                                       13
<PAGE>

B.      Additional Services. Landlord shall not be obligated to furnish any
     services or utilities other than those stated in Section 7.A. above.  If
     Tenant should require electric current, water or any other energy in excess
     of the amounts provided by Landlord pursuant to Section 7.A. above, such
     excess electric current, water or other energy requirement shall be
     supplied only with the consent of Landlord, which consent shall not be
     unreasonably withheld.  If Landlord grants such consent, Tenant shall, on
     demand, pay all costs of meter service and installation of facilities
     necessary to measure and furnish the required excess capacity, and Tenant
     shall also pay the entire cost of such excess electric current, water or
     other energy requirement.  Tenant shall also pay the entire cost of such
     additional electricity, water or other energy so required in the event
     Tenant installs any machines, equipment or devices in the Premises that do
     not constitute Customary Office Equipment and such machines, equipment or
     devices cause the temperature in the Premises, or any part thereof, to
     exceed the temperatures the Building's mechanical system would be able to
     maintain in the Premises were it not for such machines, equipment or
     devices, and Landlord also reserves the right to install supplementary air
     conditioning units in the Premises, and the costs thereof, including the
     cost of installation and the cost of operation and maintenance thereof,
     shall be paid by Tenant to Landlord upon demand.

C.      Interruption of Services. Landlord does not warrant that the services
     provided for in this Section 7 will be free from any irregularity or
     stoppage.  Landlord will use due diligence to resume the service upon any
     irregularity or stoppage; provided, however, no irregularity or stoppage of
     any of these services will create any liability for Landlord, constitute an
     eviction, actual or constructive, of Tenant, or cause any abatement of the
     Rent payable under this Lease, or in any manner or for any purpose relieve
     Tenant from any of its obligations under this Lease.

8.        REPAIRS.

A.      Repairs Within the Premises. Subject to the terms of Sections 7.A.(1),
     12 and 15 hereof, Tenant will, at Tenant's own expense, keep the Premises
     in good order, repair and condition at all times during the Term, normal
     wear and tear excepted. Except for damage caused by Landlord, its
     employees, agents or contractors, Tenant shall promptly and adequately
     repair all damage to the Premises and replace or repair all damaged or
     broken fixtures and appurtenances, under the supervision and subject to the
     approval of Landlord. All work done by Tenant or its contractors (which
     contractors shall be subject to Landlord's reasonable approval) shall be
     done in a first-class workmanlike manner using only grades of materials at
     least equal in quality to those which are included in Landlord's standard
     improvements for the Building and shall comply with all insurance
     requirements and all applicable laws and ordinances and rules and
     regulations of governmental departments or agencies. At Landlord's option,
     Landlord may require that all work required to be performed by Tenant under
     this Section 8.A. be performed by Landlord or Landlord's contractor at
     Tenant's expense, in which case Tenant shall pay Landlord the reasonable
     cost of any such work, including an amount sufficient to reimburse Landlord
     for overhead and related expenses, forthwith upon being billed for the
     same, as additional Rent hereunder.

B.      Landlord's Entry. If Tenant fails to do so within a reasonable period of
     time or if Landlord deems such action necessary because of an actual or
     suspected emergency, Landlord may, but need not, make the repairs and
     replacements described in Section 8.A., and Tenant shall pay Landlord the
     reasonable cost thereof, including an amount reasonably sufficient to
     reimburse Landlord for overhead and related expenses, forthwith upon being
     billed

                                       14
<PAGE>

     for the same, as additional Rent hereunder. Landlord may, but shall not be
     required to, enter the Premises at all reasonable times during Tenant's
     ordinary business hours on prior notice (except in cases of actual or
     suspected emergency, in which case such entry may be at any time and no
     prior notice shall be required) for the purpose of inspecting, repairing or
     maintaining the same. Landlord shall take reasonable steps in connection
     with such entry to minimize any disruption to Tenant's business or its use
     of the Premises.

C.      Notice of Damage. Tenant shall give prompt notice to Landlord of (a) any
     known or apparent fire or other casualty in the Premises, (b) any known or
     apparent damage to or defect in the Premises, including the fixtures,
     equipment and appurtenances thereof, for the repair of which Landlord might
     be responsible, and (c) any known or apparent damage to or defect in any
     parts or appurtenances of the Building's sanitary, water, electrical,
     heating, air conditioning, elevator or other systems located in or passing
     through the Premises or any part thereof.  Landlord shall have no repair
     obligations whatsoever absent such notice or actual knowledge of such
     condition.

9.      ADDITIONS, IMPROVEMENTS, AND ALTERATIONS. Tenant shall not, without the
     prior written consent of Landlord, make any alterations, improvements or
     additions to the Premises.  If Landlord consents to such alterations,
     improvements or additions, it may impose such reasonable conditions with
     respect thereto as Landlord deems appropriate, including, without
     limitation, requiring Tenant to furnish Landlord with insurance against
     liabilities which may arise out of such work, a bond or other security for
     Tenant's obligations to pay for such work, plans and specifications for
     Landlord's approval prior to commencement of construction, copies of all
     permits necessary for such work and "as built" plans after completion of
     such work together with a complete breakdown of the cost of such work as
     required for purposes of Landlord's insurance or self-insurance.  The work
     necessary to make any alterations, improvements or additions to the
     Premises shall be done at Tenant's expense by employees of or contractors
     hired or approved by Landlord.  Tenant shall promptly pay, when due, the
     cost of all such work and of all decorating required by reason thereof.
     Tenant shall also pay to Landlord an amount sufficient, in Landlord's
     reasonable judgment, to reimburse Landlord for all of its overhead and
     related expenses allocable to such work.  Upon completion, Tenant shall
     deliver to Landlord, to the extent not previously received by Landlord,
     evidence of payment, contractors' affidavits, warranties and full and final
     waivers of all liens for labor, services or materials.  All alterations,
     improvements and additions to the Premises, whether temporary or permanent
     in character, made or paid for by Landlord or Tenant shall without
     compensation to Tenant become Landlord's property upon installation;
     provided, however, that Tenant may remove any of such alterations,
     additions and improvements which Landlord and Tenant agree in writing may
     be removed from the Premises at the expiration of the Term or sooner
     termination of this Lease (such agreement not to be unreasonably withheld).
     Landlord and Tenant shall enter into a written agreement concerning the
     removal of any such alterations, additions or improvements prior to or at
     the time of installation thereof.  Unless Landlord has thus expressly
     requested or approved their removal when Landlord consented to their
     installation (in which case Tenant shall remove the same as provided in
     Section 17), all such alterations, improvements and additions shall remain
     Landlord's property upon expiration or termination of this Lease by lapse
     of time or otherwise and shall be relinquished to Landlord in good order,
     repair and condition, ordinary wear and tear excepted and, subject to
     Tenant's duty to carry insurance as required by this Lease, damage from
     fire or other casualty excepted.

                                       15

10.       COVENANT AGAINST LIENS.

A.        Mechanics Liens. Tenant covenants and agrees not to suffer or permit
     any lien of mechanics or materialmen or others to be placed against the
     Complex, the Building, or the Premises with respect to work or services
     claimed to have been performed for, or materials claimed to have been
     furnished to, Tenant or the Premises. Landlord shall have the right to
     serve or to post and keep posted on the Premises, or on any part thereof,
     any notice or notices that may at any time be required or permitted by any
     law relating to, or any way affecting, the liability of the owner of the
     Complex for labor performed or materials furnished in or about the erection
     or construction of any improvements thereon at the instance of any person
     other than said owner. Within five (5) business days after written request
     by Landlord, Tenant shall post any such notices or take such other steps,
     at the expense of Tenant, as may be required or permitted by law to protect
     Landlord's interest in the Premises against such liens. In case any such
     lien attaches, Tenant covenants and agrees to promptly inform Landlord of
     such lien and to cause it to be released and removed of record within 20
     days after the filing of such lien. If Tenant fails to cause such lien to
     be released and removed of record within 20 days after the filing of such
     lien, Landlord may, at its sole option, cause the same to be paid and
     released, and Tenant shall then promptly reimburse Landlord, as additional
     Rent hereunder, for all of Landlord's costs (including attorney's fee)
     incurred in connection with such liens.

B.        Sales, Use, Income and Personal Property Taxes. Tenant shall promptly
     pay and discharge, on or prior to their due dates, all sales, use, personal
     property, income and other taxes, and all employee income tax withholdings,
     due to any governmental entity or taxing authority, failure to pay which
     might subject any of Landlord's property to a lien. If Tenant fails so to
     pay any such taxes or withholdings, and if Landlord shall reasonably
     determine that any of Landlord's property is in danger of being subject to
     a lien because of such unpaid taxes or withholdings, then Landlord shall
     have the right but not the obligation, after notice to Tenant as provided
     in Section 24.A.(1), to pay such taxes and withholdings, and the amount so
     paid, together with interest thereon as provided in Section 29.B., shall
     constitute additional Rent under this Lease due and payable from the date
     so paid by Landlord.

11.       INSURANCE.

A.        Waiver of Subrogation. Landlord and Tenant each hereby waive any and
     every claim for recovery from the other for any and all loss of or damage
     to the Complex or the Premises or to the contents thereof, which loss or
     damage is of a type insurable under "all risk" casualty insurance policies
     available at the time such loss or damage was sustained. Inasmuch as this
     mutual waiver will preclude the assignment of any such claim by subrogation
     (or otherwise) to an insurance company (or any other person), Landlord and
     Tenant each agree to give written notice of the terms of this mutual waiver
     to each insurance company which has issued, or in the future may issue, a
     policy of casualty insurance to such party. Each party shall also have each
     such insurance policy properly endorsed, if necessary, to prevent the
     invalidation of such insurance coverage by reason of such waiver. Tenant
     shall obtain from its insurers and deliver to Landlord endorsements or
     written waivers of subrogation, or other written evidence satisfactory to
     Landlord, that each of Tenant's insurers is bound by Tenant's waiver of
     subrogation. If Landlord adopts a plan of self-insurance with respect to
     those portions of the Building or Premises which Landlord may be obligated
     to repair or restore under Section 12A (and Landlord reserves the right to
     adopt such a plan) Landlord's waiver of claims contained in the first
     sentence of this paragraph will continue to be effective as long as
     Tenant's waiver of subrogation remains in effect.

                                       16
<PAGE>

B.        Coverage. Tenant agrees, at its cost, to obtain and keep in force
     during the Term the following described insurance, in form and substance,
     and issued by companies, acceptable to Landlord in its reasonable judgment,
     provided that Landlord may from time to time require reasonable increases
     in the limits set forth below:

     (1)  Liability Insurance.  Commercial General liability insurance with
          combined single limits of not less than  $2,000,000 for bodily injury,
          personal injury and property damage occurring in or about or related
          to the use of the Premises and assumed contractual liability with
          respect to Tenant's obligations under Section 13.

     (2)  Property Insurance.  An "all risk" casualty insurance policy in the
          amount equal to the full replacement cost of all leasehold
          improvements, alterations and additions to the Premises which are in
          excess of or in addition to Building Standard, and of Tenant's office
          furniture, trade fixtures, office equipment, merchandise and all other
          items of Tenant's property on the Premises.

     (3)  Workers' Compensation and Tenant's Contractors.  A workers'
          compensation insurance policy in at least the amount required by law,
          and employer's liability insurance with limits of at least $500,000
          each occurrence.  In addition, Tenant shall require all of Tenant's
          contractors and suppliers that will perform work on the Premises to
          deliver to Landlord, prior to the commencement of such work,
          certificates of insurance evidencing that such contractors carry
          Commercial General liability insurance in the amount of at least
          $1,000,000, workers' compensation insurance in the amount required by
          law, and employer's liability insurance with limits of at least
          $500,000 each occurrence.  The requirements of this subsection (3)
          shall also apply independently to all subcontractors and suppliers to
          Tenant's contractors and suppliers unless claims by or against them
          are covered by the insurance carried by Tenant's contractors and
          suppliers.

     (4)  Form of Policies.  All policies evidencing the coverage required under
          this Section 11.B. shall be issued by carriers with a rating of A-X or
          better by A.M. Best Company, Inc. and licensed to do business in the
          State of Colorado (except that the worker's compensation insurance may
          be provided by the State of Colorado) and shall provide that (a) the
          coverage is primary and non-contributing to any insurance that may be
          carried by Landlord; (b) the coverage cannot be canceled, modified,
          reduced, or otherwise materially changed except after 30 days' prior
          written notice to Landlord, and (c) Landlord is a named additional
          insured (except that Landlord need not be so named in Tenant's
          worker's compensation policy).  Tenant shall furnish Landlord with
          true copies of all policies or certificates of insurance evidencing
          such coverage promptly on receipt.  Notwithstanding that Landlord is a
          named additional insured, Tenant shall be solely responsible for
          timely payment of all premiums and timely performance of all other
          obligations under all policies, including but not limited to all
          reporting requirements.  True copies of all receipts of payment in
          full of premiums shall be given by Tenant to Landlord not less than 15
          days before the due dates of such premiums.

C.        Avoid Action Increasing Rates. Tenant shall comply with all
     applicable laws and ordinances, all orders and decrees of court and all
     requirements of other governmental

                                       17
<PAGE>

     authorities, and shall not, directly or indirectly, make any use of the
     Building, Premises or Complex which may thereby be prohibited or be
     dangerous to person or property or which may jeopardize any insurance
     coverage on the Building, Premises or Complex, or which may increase the
     cost of insurance or require additional insurance coverage (unless Tenant
     elects to pay the full costs of such increased or additional coverages, in
     which case such costs shall be due to Landlord upon presentation of an
     invoice or invoices therefor, as additional Rent hereunder). In no event
     shall Tenant permit in the Premises flammables such as gasoline,
     turpentine, kerosene, naphtha and benzine, or explosives or any other
     article of intrinsically dangerous nature, and in no event shall Tenant,
     its agents, employees, invitees, visitors, licensees, contractors,
     suppliers or workmen bring such flammables or other intrinsically dangerous
     articles into the Complex. If by reason of the failure of Tenant to comply
     with the provisions of this Section 11.C., (i) any insurance coverage is
     jeopardized, Landlord shall have the option to terminate this Lease after
     notice and an opportunity to cure as provided in Section 24.A (3) below; or
     (ii) insurance premiums are increased or additional coverage is required,
     Landlord may require Tenant to make immediate payment of the increased
     insurance premium as additional Rent hereunder.

D.        Notices by Tenant's Insurance Carrier to Landlord. Whenever in this
     Lease (whether in Section 11.B. or elsewhere), any notice is given or is
     required to be given, to Landlord by Tenant's insurance carrier, such
     notice must actually be given by each such carrier to Landlord, and any
     provision in any policy, certificate of insurance or elsewhere providing
     that notice to another insured under that policy, or to any other person,
     shall constitute or be deemed to be notice to Landlord shall be ineffective
     and shall be changed by endorsement so that notice is actually given by
     such carrier to Landlord itself. Tenant shall also provide to Landlord such
     written evidence of compliance with this Section 11.E. as Landlord may
     reasonably request.

12.       FIRE OR CASUALTY.

A.        Restoration - Cancellation upon Major Damage. If the Premises or the
     Building shall be damaged by fire or other casualty Landlord shall,
     promptly after learning of such damage, notify Tenant in writing of
     Landlord's estimate of the time necessary to repair or restore such damage.
     If Landlord reasonably estimates that repair or restoration of all of such
     damage that was caused to the Premises or to any other portion of the
     Building necessary for Tenant's occupancy cannot be completed within 180
     days from the date of such damage, then Tenant shall have the option to
     terminate this Lease.  If such damage has rendered all or a substantial
     portion of the Premises or the Building untenantable, Landlord shall have
     the option to terminate this Lease.  Any option to terminate granted
     hereunder must be exercised by written notice to the other party given
     within 10 days after Landlord delivers to Tenant the notice of estimated
     repair time.  If either party exercises its option to terminate this Lease,
     the Term shall expire and this Lease shall terminate 10 days after notice
     of termination is delivered; provided, however, that Rent for the period
     commencing on the date of such damage until the date this Lease terminates
     shall be reduced to the reasonable value of any use or occupation of the
     Premises by Tenant during such period.  If neither party so terminates this
     Lease, then Landlord shall repair and restore such damage with reasonable
     promptness, subject to delays for insurance adjustments and delays caused
     by matters beyond Landlord's control.  If Landlord fails to complete the
     repairs within 210 days from the date of such damage, then Tenant shall
     again have the option to terminate this Lease, by written notice delivered
     to Landlord within 10 days after the expiration of such 210-day period.
     Whether or not this Lease is terminated, all

                                       18
<PAGE>

     proceeds of insurance required to be carried by Tenant with respect to
     alterations, additions, and improvements under this Lease shall be used for
     such repairs and restoration as are made, and paid to Landlord to the
     extent not made. Except for the termination right of Tenant set forth
     above, Landlord shall have no liability to Tenant in the event such repairs
     and restoration are not in fact completed within the time period estimated
     by Landlord.

B.        Rent Abatement. In the event any fire or casualty damage renders the
     Premises untenantable and if this Lease shall not be terminated pursuant to
     Section 12.A. hereof by reason of such damage, then Rent shall abate during
     the period beginning with the date of such damage and ending with the date
     when Landlord has substantially completed its obligations under this
     Section 12.  Such abatement shall be in an amount bearing the same ratio to
     the total amount of Rent for such period as the untenantable portion of the
     Premises bears to the entire Premises.  In no event will Landlord be liable
     for any inconvenience or annoyance to Tenant or injury to the business of
     Tenant resulting in any way from damage caused by fire or other casualty or
     the repair of such damage, provided however that, to the extent Tenant
     remains in possession of a portion of the Premises, Landlord will take all
     reasonable steps to minimize the disruption to Tenant's business and use of
     such portion of the Premises during the period of repair.

13.       WAIVER OF CLAIMS - INDEMNIFICATION. To the extent not prohibited by
     law, Landlord and its partners, and its and their partners, venturers,
     managers, officers, agents, servants, employees, affiliated limited
     liability companies, and other affiliated entities shall not be liable for,
     and Tenant waives all claims for, any damages to person or property, or
     resulting from the loss of use thereof, or any loss of profits or damages
     from business interruption, sustained by Tenant or by Tenant's partners,
     officers, agents, servants or employees due to the Building or the Complex
     or any part thereof or any appurtenances thereof becoming out of repair, or
     due to the happening of any accident or event in or about the Building or
     Complex, or due to any act or neglect of any tenant or occupant of the
     Building or Complex or of any other person; provided, however, that such
     waiver shall not apply to claims or damages arising from or related to the
     gross negligence or willful misconduct of Landlord. This provision shall
     apply particularly (but not exclusively) to damage caused by gas,
     electricity, snow, frost, steam, sewage, sewer gas or odors, fire, water or
     by the bursting or leaking of pipes, faucets, sprinklers, plumbing
     fixtures, and windows, and shall apply without distinction as to the person
     whose act or neglect was responsible for the damage and whether the damage
     was due to any of the causes specifically enumerated above or to some other
     cause of an entirely different kind (other than the gross negligence or
     willful misconduct of Landlord). Tenant further agrees that all personal
     property upon the Premises, or upon loading docks, receiving and holding
     areas or parking areas, of the Building or the Complex, shall be at the
     risk of Tenant only, and that Landlord shall not be liable for any loss or
     damage thereto or theft thereof, unless caused by the gross negligence or
     willful misconduct of Landlord. Without limitation of any other provisions
     hereof and to the extent not prohibited by law, Tenant agrees to defend,
     protect, indemnify and save harmless Landlord and its partners, and its and
     their partners, venturers, managers, officers, agents, servants and
     employees, affiliated limited liability companies, and other affiliated
     entities from and against all claims, liabilities, losses, damages or
     expenses made against or incurred by Landlord attributable to the
     negligence, willful misconduct or breach of this Lease by Tenant or its
     partners, officers, servants, agents, employees, contractors, suppliers,
     licensees, visitors, workmen or invitees.

                                       19
<PAGE>

14.       NONWAIVER; ACCEPTANCE OF RENT OR PERFORMANCE AFTER BREACH. No waiver
     of any condition, covenant or provision of this Lease shall be implied by
     any failure of either party to enforce any remedy on account of the
     violation of such condition, covenant or provision even if such violation
     be continued or repeated subsequently, and no express waiver shall affect
     any condition, covenant or provision other than the one specified in such
     waiver and that one only for the time and in the manner specifically
     stated. Acceptance by Landlord of Rent or other performance by Tenant,
     after Landlord has knowledge of any breach or default under this Lease by
     Tenant, shall not constitute a waiver by Landlord of such breach or
     default, nor prevent Landlord from enforcing any remedy for that or any
     other breach or default.

15.       CONDEMNATION. If the whole or substantially the whole of the Building,
     the Premises or the parking facilities in the Complex is taken for any
     public or quasi-public use under any governmental law, ordinance or
     regulation or by right of eminent domain or is sold to the condemning
     authority in lieu of condemnation, then this Lease will terminate as of the
     earlier of the date when title to or physical possession of the Building,
     the Premises or the parking facilities in the Complex is taken by the
     condemning authority. If less than the whole or substantially the whole of
     the Building, the Premises or the parking facilities in the Complex is thus
     taken or sold and if, after such partial taking, in Landlord's reasonable
     judgment, alteration or reconstruction of the Complex is not economically
     justified, Landlord (whether or not the Premises are affected thereby) may
     terminate this Lease by giving written notice to Tenant within 60 days
     after the taking or sale. If over 50% of the Premises is thus taken or
     sold, Tenant may terminate this Lease if, and only if, in Tenant's
     reasonable judgment, the Premises cannot be operated by Tenant in an
     economically viable fashion because of such partial taking or sale. Such
     termination by Tenant must be exercised by written notice to Landlord given
     not later than 60 days after Tenant is notified of the taking or sale of
     the Premises. Termination by Landlord or Tenant shall be effective as of
     the earlier of the date when title to or physical possession of the
     applicable portion of the Complex, the Building or the Premises is taken by
     the condemning authority. If neither Landlord nor Tenant elects to
     terminate this Lease upon a partial taking or sale of a portion of the
     Premises, the Rent payable under this Lease will be diminished by an amount
     allocable to the portion of the Premises which was so taken or sold. If
     this Lease is not terminated upon a partial taking or sale, Landlord will,
     at Landlord's sole expense, promptly restore and reconstruct the Complex,
     the Building and the Premises to substantially their former condition to
     the extent that the same may be feasible. Landlord in no event shall be
     required to spend for such restoration or reconstruction an amount in
     excess of the net amount received by Landlord as compensation or damages
     for the part of the Complex, the Building or the Premises so taken or sold.
     As between the parties to this Lease, Landlord will be entitled to receive
     all of the compensation and damages awarded upon a taking or sale of any
     part or all of the Complex, the Building or the Premises including any
     award for the value of any unexpired term of this Lease and Tenant will not
     be entitled to and expressly waives in favor of Landlord all claim to any
     of the award or damages, including any compensation for the unexpired term
     of this Lease. The foregoing shall not in any way restrict Tenant from
     asserting a claim in a separate proceeding against the condemning authority
     (if and to the extent permitted by law) for any compensation or damages
     resulting from the taking of Tenant's trade fixtures or for moving expenses
     or business relocation expenses incurred as a result of such condemnation.

16.       ASSIGNMENT AND SUBLETTING. Tenant shall not, without the prior written
     consent of Landlord, (i) assign, convey, encumber, or mortgage this Lease
     or any interest

                                       20
<PAGE>

     hereunder; (ii) suffer to occur or permit to exist any assignment of this
     Lease or any interest hereunder, or any recordable lien upon Tenant's
     interest or any part thereof, voluntarily, involuntarily or by operation of
     law; (iii) sublet the Premises or any part thereof; or (iv) permit the use
     of the Premises or any part thereof by any parties other than Tenant and
     its employees and their lawful licensees and invitees. For purposes of the
     preceding sentence, any change in ownership of Tenant or of any guarantor
     of Tenant's obligations under this Lease (a "Guarantor") shall be deemed to
     be an assignment of this Lease. A "change in ownership" shall be deemed to
     have occurred (a)(i) for a publicly traded corporation, when there is a
     change of effective control; (ii) for any other entity, in the event of any
     circumstance where the voting interest of any party or group of parties
     increases or decreases by more than one-third of the entire voting
     interest; or (b) upon the distribution of over 50% of any entity's assets,
     or if the value of assets sold (net of undistributed consideration
     received) exceeds 50% of asset value. Landlord's consent to any assignment,
     subletting, transfer, or to any other matter set forth above in this
     Section 16, shall not constitute a waiver of Landlord's right to withhold
     its consent to any future assignment, subletting or transfer, or to any
     such other matter.

     Tenant shall give Landlord written notice of any proposed sublease or
assignment which notice shall contain the name of the proposed sublessee or
assignee and proposed principal terms thereof.  With respect to any proposed
assignment of all of the Premises or sublease of all of the Premises which is to
occur subsequent to the earlier of (i) the date upon which at least 85% of the
Rentable Area of the Building has been leased, or (ii) twenty-four months after
the Commencement Date, Landlord agrees that it shall not unreasonably withhold
its consent to such assignment or sublease; provided, however, that reasonable
grounds for the withholding of consent shall include, without limitation,
whether the use by the proposed assignee or sublessee will be the same general
administrative office use as that of Tenant (and if not, whether the proposed
use would be an appropriate use for a Class A office building in the Denver
Technological Center, including without limitation whether the density of the
proposed use would result in an occupancy level of greater than five (5)
occupants per 1000 square feet of Rentable Area), and Landlord's judgment of the
proposed assignee's or subtenant's insufficient financial capacity or business
experience to perform Tenant's obligations under this Lease or of its poor
business reputation.  With respect to any proposed assignment or sublease other
than those specified in the preceding sentence, Landlord may withhold its
consent in its sole discretion, for any reason, or for no reason.

     Upon any assignment or subletting by Tenant, (i) unless agreed in writing
by Landlord, the original Tenant and any Guarantor shall not be released from
any covenant or obligation under this Lease, and (ii) Landlord shall be entitled
to receive and collect, either from Tenant or directly from the assignee or
subtenant, all of the Rent and other sums payable by Tenant under this Lease.
In addition, Landlord shall be entitled to so receive and collect fifty percent
(50%) of the consideration, if any, that the assignee or subtenant is required
to pay for the use and enjoyment of Tenant's rights under this Lease in excess
of the amounts payable by Tenant to Landlord under this Lease, after deducting
therefrom all of the expenses incurred by Tenant in connection with such
assignment or sublease (whether such excess is payable by such assignee or
subtenant in monthly installments, in a lump sum, or otherwise).

     If Tenant believes that Landlord has unlawfully or unreasonably withheld
its consent to a proposed assignment or sublease to which Landlord has agreed
not to unreasonably withhold its consent, Tenant shall not have any right to
recover damages or to terminate this Lease, but Tenant's sole remedy shall be to
seek a declaratory judgment that Landlord has unlawfully or

                                       21
<PAGE>

unreasonably withheld its consent or an order for specific performance or
mandatory injunction that Landlord give its consent.

     Tenant acknowledges that the conditions, covenants and provisions in this
Lease, including but not limited to those in this Section 16, have been fully
and freely negotiated.

17.       SURRENDER OF POSSESSION. Upon the expiration or termination of the
     Term, whether by lapse of time or otherwise, or upon the termination of
     Tenant's right of possession, Tenant shall forthwith surrender the Premises
     to Landlord in good order, repair and condition, ordinary wear and tear
     excepted, and, subject to Tenant's duty to carry insurance as required by
     this Lease, damage by fire or other casualty excepted. Except as provided
     in Sections 5.A and 9 to the contrary, all alterations, improvements and
     additions to the Premises, made or paid for by Landlord or Tenant, shall
     without compensation to Tenant become Landlord's property upon
     installation. Except as provided in Sections 5.A and 9 to the contrary, all
     such alterations, improvements and additions shall remain Landlord's
     property at the termination or expiration of this Lease whether by lapse of
     time or otherwise, and shall be relinquished to Landlord in good order,
     repair and condition, ordinary wear and tear and, subject to Tenant's duty
     to carry insurance as required by this Lease, damage by fire or other
     casualty excepted. Tenant agrees to remove, at such expiration or
     termination of the Term or of its right of possession, the following items
     of property: office furniture, trade fixtures, office equipment and all
     other items of Tenant's property or temporary improvements on the Premises,
     and Tenant shall pay to Landlord upon demand the cost of repairing any
     damage to the Premises and to the Building caused by any such removal. If
     Tenant shall fail or refuse to remove any such property from the Premises
     by the date on which the Term expires, or if Tenant's right to possession
     terminates earlier, by the date which is five (5) business days after such
     right to possession has terminated, Tenant shall be conclusively presumed
     to have abandoned the same, and title thereto shall thereupon pass to
     Landlord without any cost either by set-off, credit, allowance or
     otherwise, and Landlord may at its option accept the title to such property
     or at Tenant's expense may (i) remove the same or any part thereof in any
     manner that Landlord shall choose, and (ii) store, destroy or otherwise
     dispose of the same without incurring liability to Tenant or any other
     person.

18.       PERSONAL PROPERTY.

A.        Responsibility. Tenant shall be solely responsible for all costs and
     expenses related to personal property used or stored in the Premises.
     Without limiting the foregoing, Tenant shall pay any taxes or other
     governmental impositions levied upon or assessed against such personal
     property, or upon Tenant for the ownership or use of such personal
     property, on or before the due date for payment thereof. Such personal
     property taxes or impositions are not included in Taxes.

B.        Taxes on Certain Improvements, Alterations and Conditions. Tenant
     shall also be responsible for all taxes or other governmental impositions
     levied upon or assessed against any improvements, alterations, or additions
     to the Premises to the extent that the same exceed or are in addition to
     Building Standard, and if the taxing authorities do not separately levy or
     assess such excess or additional improvements, alterations, or additions,
     Landlord may make a reasonable allocation of such taxes or other
     governmental impositions to the same.

C.        Landlord's Lien.   Intentionally Deleted.

                                       22
<PAGE>

19.       HOLDING OVER. If Tenant shall hold over after the expiration or
     termination of the Term or of Tenant's right of possession, without written
     agreement providing otherwise, Tenant shall be deemed to be a tenant from
     month to month, at a monthly Annual Rent, payable in advance, equal to 150%
     of monthly Annual Rent payable during the last Lease Year of the Term, and
     Tenant shall be bound by all of the other covenants, conditions and
     provisions of this Lease as the same may apply to a month-to-month tenancy.
     Nothing contained herein shall be construed to give Tenant the right to
     hold over at any time, and Landlord may exercise any and all remedies at
     law or in equity to recover possession of the Premises, as well as any
     damages incurred by Landlord, due to Tenant's failure to vacate the
     Premises and deliver possession to Landlord as herein provided.

20.       ESTOPPEL CERTIFICATE. Tenant agrees that from time to time upon not
     less than ten (10) days' prior request by Landlord, Tenant will deliver to
     Landlord a statement in writing certifying (i) that this Lease is
     unmodified and in full force and effect (or if there have been
     modifications that the Lease as modified is in full force and effect); (ii)
     the dates on which the Commencement Date occurred and the Expiration Date
     will occur; (iii) the dates on which Tenant began paying Rent and that no
     Rent has been paid in advance of the required payment dates; (iv) that to
     the best of Tenant's knowledge, neither Tenant nor Landlord is in default
     under any provision of this Lease, or, if a default exists, the nature
     thereof in detail; (v) that Tenant has no existing defenses or off-sets to
     the enforcement of the Lease or, if there are any, specifying same; (vi)
     provided such events have occurred, that Tenant has accepted and occupied
     the Premises and that the Premises have been completed in accordance with
     the terms hereof; and (vii) such other matters as may be reasonably
     requested by Landlord, so long as the same do not materially alter Tenant's
     obligations under this Lease. It is intended that any such statement may be
     relied upon by Landlord, any prospective purchaser or tenant of the
     Building, any mortgagee or prospective mortgagees thereof or any
     prospective assignee of any mortgage thereon.

21.       OBLIGATIONS TO MORTGAGEES AND LESSORS.

A.        Subordination. At Landlord's option, this Lease may be made subject
     and subordinate to future ground or underlying leases of the Land and to
     the lien of any mortgages or deeds of trust, hereafter in force against the
     Land, Complex or Building, or any of them, and to all renewals, extensions,
     modifications, consolidations and replacements thereof, and to all advances
     made or hereafter to be made upon the security of such mortgages or deeds
     of trust. Tenant shall, within 10 days after Landlord's request for the
     same, execute such further instruments or assurances as Landlord may
     reasonably deem necessary to evidence or confirm the subordination of this
     Lease to any such mortgages, deeds of trust, ground leases or underlying
     leases, or, if requested by any mortgagee, beneficiary of a deed of trust,
     or underlying or ground lessor, to make Tenant's interest in this Lease
     superior to the interest of such mortgagee, beneficiary of a deed of trust,
     or underlying or ground lessor, so long as the same do not materially alter
     Tenant's obligations under this Lease. It is further agreed that upon the
     request of the mortgagee or beneficiary of a deed of trust, if the mortgage
     or deed of trust shall be foreclosed, or the transferee if the Building
     shall be conveyed in lieu of foreclosure, Tenant will attorn, as Tenant
     under this Lease, to the purchaser at any foreclosure sale or transferee
     under such conveyance, or upon request of the ground or underlying lessor,
     if any ground or underlying lease shall be terminated, Tenant will attorn,
     as Tenant under this Lease, to the ground or underlying lessor; and, in
     either case, Tenant will execute, within 10 days after a request therefor,
     such instruments as may be necessary or appropriate to evidence

                                       23
<PAGE>

     such attornment, so long as the same do not materially alter Tenant's
     obligations under this Lease,.

B.   Notice to Landlord, Mortgagees, and Lessors. In the event of any act or
     omission by Landlord which would give Tenant the right to seek damages or
     specific performance from Landlord or the right to terminate this Lease,
     Tenant will not sue for such damages or specific performance or exercise
     any such right to terminate until (i) it shall have given written notice of
     the act or omission to Landlord and to the holder(s) of the indebtedness or
     other obligations secured by any mortgage or deed of trust affecting the
     Premises and lessor(s) of any ground or underlying lease, if the name and
     address of such holder(s) or lessor(s) have been furnished to Tenant, and
     (ii) the lesser of 30 days or the applicable grace period hereunder for
     remedying the act or omission has elapsed following the giving of the
     notice, during which time Landlord and such holder(s) or lessor(s), or any
     of them, their agents or employees, will be entitled to enter upon the
     Premises and do therein whatever may be necessary to remedy the act or
     omission.

22.     CERTAIN RIGHTS RESERVED BY LANDLORD. Landlord shall have the following
     rights, each of which Landlord may exercise without notice to Tenant
     (except as expressly provided below) and without liability to Tenant for
     damage or injury to property, person or business on account of the exercise
     thereof, and the exercise of any such rights shall not be deemed to
     constitute an eviction or disturbance of Tenant's use or possession of the
     Premises and shall not give rise to any claim for set-off or abatement of
     rent or any other claim:

        (1)     except as provided in Section 6 of Exhibit A, to change the name
                or street address of the Complex or the Building, with three (3)
                months' prior notice to Tenant;

        (2)     to install, affix and maintain any and all signs on the exterior
                and on the interior of the Building or anywhere on Land or in
                the Complex (and except as provided in Section 8 of Exhibit A,
                Tenant agrees not to place or maintain any sign or other
                advertising matter outside the Premises or inside the Premises
                so as to be visible from outside the Premises, without the prior
                written permission of Landlord);

        (3)     to decorate or to make repairs, alterations, additions, or
                improvements, whether structural or otherwise, in and about the
                Building or Complex, or any part thereof, and for such purposes
                to enter upon the Premises, and, during the continuance of any
                of such work, to temporarily close doors, entryways, public
                space and corridors in the Building and to interrupt or
                temporarily suspend services or use of facilities, all without
                affecting any of Tenant's obligations hereunder, so long as
                Landlord has given Tenant reasonable prior notice of any such
                actions in the Premises. Landlord shall take reasonable steps in
                connection with such actions to minimize any disruption to
                Tenant's business or its use of the Premises;

        (4)     to the extent permitted by law, to retain at all times, and to
                use in appropriate instances, keys to all doors within and into
                the Premises. If the security system in the Premises is one
                which has been installed by and is maintained by Landlord,
                Tenant agrees to purchase only from Landlord additional
                duplicate keys as required. Unless approved in writing by
                Landlord as part of either the initial security system in the
                Premises or as part of an approved modification

                                       24
<PAGE>

                thereto, Tenant agrees to change no locks, and not to affix
                locks on doors without the prior written consent of Landlord.
                Notwithstanding the provisions for Landlord's access to portions
                of the Premises, Tenant relieves and releases the Landlord of
                all responsibility arising out of theft, robbery and pilferage,
                unless due to the gross negligence or willful misconduct of
                Landlord. Upon the expiration or termination of the Term or of
                Tenant's right to possession, Tenant shall return all keys to
                Landlord and shall disclose to Landlord the combination of any
                safes, cabinets or vaults left in the Premises;

        (5)     to designate Building Standard window coverings for all windows
                in the Building and to designate and approve, prior to
                installation, all types of additional window shades, blinds or
                draperies, if any;

        (6)     to approve the weight, size and location of safes, vaults and
                other heavy equipment and articles in and about the Premises and
                the Building (so as not to exceed the lesser of the legal live
                load per square foot or the live load per square foot designated
                by the structural engineers for the Building), and to require
                all such items and furniture and similar items to be moved into
                or out of the Building and Premises only at such times and in
                such manner as Landlord shall direct in writing. Movements of
                Tenant's property into or out of the Building and within the
                Building are entirely at the risk and responsibility of Tenant
                and Landlord reserves the right to require Landlord's
                permission, not to be unreasonably withheld, before allowing any
                property to be moved into or out of the Building;

        (7)     to show the Premises to prospective tenants at reasonable hours
                during the last six months of the Term; and

        (8)     to erect, use and maintain unexposed pipes, ducts, wiring and
                conduits, and appurtenances thereto, in and through the
                Premises.

23.       RULES AND REGULATIONS. Tenant covenants and agrees to keep and observe
     the rules and regulations attached to this Lease as Exhibit E and made a
     part hereof. Landlord shall have the right from time to time to amend such
     rules and regulations and to prescribe additional rules and regulations
     which, in its reasonable judgment, may be desirable for the use, entry,
     operation and management of the Premises, the Building and the Complex,
     each of which amended and additional rules and regulations shall become a
     part of this Lease. Tenant shall comply with such rules and regulations
     provided, however, that such rules and regulations shall not contradict or
     abrogate any right or privilege herein expressly granted to Tenant.

24.       DEFAULT AND REMEDIES.

A.        Events of Default. Each of the following shall constitute an "Event
of Default" under this Lease:

     (1)  Failure to Pay Rent or Other Amounts When Due.  If Tenant fails more
          than two times during any twelve-month period during the Term to pay
          within five (5) days of the date when due Annual Rent, Additional
          Rent, or any other Rent or amounts payable by Tenant under the terms
          of this Lease.  Tenant shall in all events pay interest as provided in
          Section 29.B. on all Annual Rent, Additional

                                       25
<PAGE>

          Rent and other Rent and amounts owed from their respective original
          due dates until paid.

     (2)  Failure to Deliver Required Documents.  If Tenant fails to deliver an
          estoppel certificate required by Section 20 above, or an instrument
          required by Section 21.A. above, in either case within 10 days after
          Tenant's receipt of a request therefor.

     (3)  Violation of Other Lease Terms.  If Tenant breaches or fails to comply
          with any other covenant or provision of this Lease applicable to
          Tenant, and such breach or failure to comply is not covered by the
          provisions of Section 24.A.(1) above and continues for a period of 20
          days after notice thereof by Landlord to Tenant, or, if such breach or
          failure to comply cannot be reasonably cured within such 20-day
          period, if Tenant shall not in good faith commence to cure such breach
          or failure to comply within such 20-day period or shall not diligently
          complete such cure within 60 days after such notice from Landlord;
          provided, however, that if such breach or failure to comply causes or
          results in (i) a dangerous condition in the Premises, Building or
          Complex, (ii) any insurance coverage carried by Landlord or Tenant
          with respect to the Premises, Building or Complex being jeopardized,
          or (iii) a material disturbance to another tenant of the Complex, then
          an Event of Default shall exist if such breach or failure to comply is
          not cured as soon as reasonably possible after notice thereof by
          Landlord to Tenant, and in any event is not cured within 30 days after
          such notice.  For purposes of this Section 24.A.(2), financial
          inability shall not be deemed a reasonable ground for failure to
          immediately cure any breach of, or failure to comply with, the
          covenants and provisions of this Lease.

     (4)  Nonoccupancy of Demised Premises.  If Tenant shall fail to
          substantially occupy and use the Premises within 15 days after
          commencement of the Term or shall leave the Premises unoccupied for 15
          consecutive days or shall vacate and abandon the Premises.

     (5)  Transfer of Interest Without Consent.  If Tenant's interest under this
          Lease or in the Premises shall, in whole or in part, be transferred to
          or pass to or devolve upon any other party in violation of the
          covenants and provisions of Section 16, or if Tenant shall in any
          other way fail to comply with Section 16.

     (6)  Execution and Attachment Against Tenant.  If Tenant's interest under
          this Lease or in the Premises shall be taken upon execution or by
          other process of law directed against Tenant, or shall be subject to
          any attachment at the instance of any creditor or claimant against
          Tenant and said attachment shall not be discharged or disposed of
          within 15 days after the levy thereof.

     (7)  Bankruptcy or Related Proceedings.  If Tenant shall file a petition in
          bankruptcy or insolvency or for reorganization or arrangement or to
          delay, reduce or modify Tenant's debts or obligations, under the
          bankruptcy laws of the United States or under any similar act of any
          state, or Tenant shall voluntarily take advantage of any such law or
          act by answer or otherwise, or shall be dissolved, or shall be
          declared insolvent, or shall make an assignment for the benefit of
          creditors or, if involuntary proceedings under any such bankruptcy or

                                       26
<PAGE>

          insolvency law or for the dissolution of Tenant shall be instituted
          against Tenant or a receiver or trustee shall be appointed for the
          Premises or for all or substantially all of the property of Tenant,
          and such proceedings shall not be dismissed or such receivership or
          trusteeship vacated within 60 days after such institution or
          appointment.

     (8)  Maintenance of Tenant's Legal Status.  If (i) Tenant is a corporation,
          partnership, limited liability company, limited partnership or other
          entity and Tenant shall for any reason fail to maintain its existence
          and good standing under the laws of the jurisdiction of its formation;
          or (ii) if Tenant is an entity formed under the laws of a jurisdiction
          other than Colorado, and if Tenant or any of its principals, partners
          or other constituents is required by the laws of Colorado to qualify
          and maintain its qualification to transact business in Colorado, and
          Tenant or any of such principals, partners or constituents fails for
          any reason to do so; or ( iii) if Tenant is a partnership or other
          entity and Tenant is dissolved or otherwise liquidated.

B.        Landlord's Remedies. Subject to Section 29.S, time is of the essence
     hereof.  Upon the occurrence of any Event of Default, Landlord shall have,
     in addition to all other rights and remedies provided in this Lease or at
     law or in equity, the right, at Landlord's election, then or at any time
     thereafter, to exercise any one or more of the following remedies:

        (1)     Cure by Landlord. Upon an Event of Default, Landlord may, at
                Landlord's option, but without obligation to do so, and without
                releasing Tenant from any obligations under this Lease, make any
                payment or take any action as Landlord may deem necessary or
                desirable to cure any such Event of Default in such manner and
                to such extent as Landlord may deem necessary or desirable.
                Landlord may do so without demand on, or written notice to,
                Tenant and without giving Tenant an opportunity to cure such
                Event of Default. Tenant covenants and agrees to pay to
                Landlord, within 10 days after demand, all advances, costs and
                expenses of Landlord in connection with the making of any such
                payment or the taking of any such action, including reasonable
                attorneys' fees, together with interest at the rate described in
                Section 29.B., from the date of payment of any such advances,
                costs and expenses by Landlord.

        (2)     Termination of Lease and Damages. Upon an Event of Default,
                Landlord may terminate this Lease, effective at such time as may
                be specified by written notice to Tenant, and demand (and, if
                such demand is refused, recover) possession of the Premises from
                Tenant. Tenant shall remain liable to Landlord for damages in an
                amount equal to the total of the following:

                i)   the cost, including reasonable attorneys' fees, of
                     demanding and recovering the Premises;

                ii)  all unpaid Annual Rent, Additional Rent and any other Rent
                     earned at the time of termination of this Lease, plus
                     interest thereon at the rate as set out in Section 29.B.;
                     and

                                       27
<PAGE>

                iii) all other money and damages owed by Tenant to Landlord.

               In addition, Landlord shall also be entitled to recover from
          Tenant as damages the amounts determined at Landlord's election under
          either (x) or (y) below:

                    (x)  Annual Rent, Additional Rent and other Rent and sums
               which would have been owing by Tenant hereunder for the balance
               of the Term, had this Lease not been terminated, less the net
               proceeds, if any, received by Landlord from any reletting of the
               Premises by Landlord subsequent to such termination, after
               deducting all Landlord's expenses in connection with finding a
               new tenant and such recovery of possession and reletting,
               including tenant improvements, remodeling and refinishing space
               for a new tenant, reasonable and customary tenant inducements and
               abatements, brokerage fees or agents' commissions in connection
               therewith, redecorating costs, reasonable attorneys' fees, and
               other costs and expenses incident to recovering and reletting the
               Premises; and Landlord shall be entitled to collect and receive
               such damages from Tenant on the days on which the Annual Rent,
               Additional Rent and other Rent and sums would have been payable
               if this Lease had not been terminated.

                    (y)  Alternatively, at the option of Landlord, Landlord
               shall be entitled to recover forthwith from Tenant, as damages
               for loss of the bargain and not as a penalty, an aggregate sum
               which, at the time of such termination of this Lease, represents
               the present value of the excess, if any, of (a) the aggregate of
               the Annual Rent, Additional Rent and all other Rent and sums
               payable by Tenant hereunder that would have accrued for the
               balance of the Term (such aggregate shall be calculated by
               assuming that the monthly installment of Additional Rent due for
               the month in which termination occurs shall remain the same for
               the balance of the Calendar Year in which termination occurs and
               that the total amount of Additional Rent payable for the
               succeeding Calendar Years remaining in the Term if this Lease had
               not been terminated shall increase by 8% per Calendar Year,
               compounded annually, over the amount of Additional Rent payable
               for the Calendar Year in which termination occurs), over (b) the
               amount, if any, of such Annual Rent, Additional Rent and other
               Rent and sums which Tenant establishes Landlord can reasonably
               expect to recover by reletting the Premises for the remainder of
               the Term, taking into consideration loss of rent while finding a
               new tenant, and the costs which Landlord might incur in leasing
               the Premises to a new tenant, including those listed in paragraph
               (x) above.  Such present value shall be calculated at the rate
               commonly called the discount rate for 90-day commercial paper in
               effect at Norwest Bank Colorado, N.A. on the date of termination
               of this Lease.

     (3)  Repossession and Reletting.  Upon an Event of Default, Landlord may
          immediately or at any time thereafter, and with or without legal
          process, reenter and take possession of the Premises or any part
          thereof, without demand or

                                       28
<PAGE>

          notice and, except as may otherwise be required by law applicable to
          this Lease, repossess the same and expel Tenant and any party claiming
          by, under or through Tenant, and remove the effects of both using such
          force for such purposes as may be necessary, without being liable for
          prosecution on account thereof or being deemed guilty of any manner of
          trespass (Tenant hereby waiving any claim except claims arising out of
          Landlord's failure to exercise such care as to Tenant's property as
          may be required by law applicable to this Lease), and without
          prejudice to any remedies for arrears of rent or right to bring any
          proceeding for breach of covenants or provisions of this Lease. No
          such reentry or taking possession of the Premises by Landlord shall be
          construed as an election by Landlord to terminate this Lease unless a
          written notice of such intention is given to Tenant by Landlord. No
          notice from Landlord hereunder or under a forcible entry and detainer
          statute or similar law shall constitute an election by Landlord to
          terminate this Lease unless such notice specifically so states.
          Landlord reserves the right, following any reentry or reletting, to
          exercise its right to terminate this Lease by giving Tenant such
          written notice, in which event the Lease will terminate as specified
          in said notice. After recovering possession of the Premises, Landlord
          may, from time to time, relet the Premises, or any part thereof, for
          the account of Tenant, for such term or terms and on such agreements,
          covenants, provisions and conditions and upon such other terms as
          Landlord, in its discretion, may determine. Landlord may make such
          repairs, alterations and improvements as Landlord may consider
          appropriate to accomplish such reletting, and Tenant shall reimburse
          Landlord upon demand for all costs and expenses (together with
          interest thereon at the rate set out in Section 29.B.), which Landlord
          may incur in connection with such repossession or reletting, including
          tenant improvements, remodeling and refinishing space for a new
          tenant, reasonable and customary tenant inducements and abatements,
          brokerage fees or agents' commissions in connection therewith,
          redecorating costs, reasonable attorneys' fees, and other costs and
          expenses incident to repossessing and reletting the Premises. Landlord
          may collect and receive the rents for such reletting but, except as
          provided below with respect to Landlord's duty to use good faith
          reasonable efforts to relet the Premises, Landlord shall in no way be
          responsible or liable for any failure to relet the Premises, or any
          part thereof, or for any failure to collect any rent due upon such
          reletting. Landlord shall have no duty to attempt to mitigate its
          damages by retaking and reletting the Premises, except that if
          Landlord does retake possession of the Premises under either Section
          24.B(2) or this Section 24.B(3), Landlord shall use good faith
          reasonable efforts to relet the Premises, subject to the following
          terms, conditions and limitations: (a) any reletting of the Premises
          shall be on the terms and conditions determined by Landlord in its
          reasonable good faith discretion and to such tenants as Landlord shall
          approve in its reasonable good faith discretion. Without limiting the
          generality of the foregoing, Tenant acknowledges that, in reletting
          the Premises, Landlord may legitimately consider the effect of any
          such reletting on the Building and on any other buildings owned by
          Landlord or any other person or entity controlling, controlled by, or
          under common control with Landlord, or otherwise affiliated with
          Landlord (which parties are referred to herein collectively as
          "Landlord Affiliates"), and, therefore, may decide not to lease the
          Premises at rates which are lower than Landlord is otherwise
          endeavoring to maintain in the Building, or at rates which are lower
          than the rate

                                       29
<PAGE>

          that Landlord believes to be appropriate for the Premises; and (b)
          Tenant recognizes that Landlord and Landlord's Affiliates currently
          and in the future may have vacant space in the Building and other
          buildings and may in the future also have vacant space in new projects
          in competition with the Premises. In no event shall Landlord be
          obligated to use any effort to relet the Premises in preference to
          leasing any such other vacant space then available for leasing by
          Landlord or any of Landlord's Affiliates. Landlord shall not be deemed
          to have failed to mitigate damages solely on account of the leasing of
          other space which Landlord or Landlord's Affiliates have available
          instead of the reletting of the Premises. Notwithstanding Landlord's
          recovery of possession of the Premises, Tenant shall continue to pay
          on the dates herein specified, the Annual Rent, Additional Rent and
          other Rent and sums which would be payable hereunder if such
          repossession had not occurred, together with interest thereon as set
          forth in Section 29.B., less a credit for the net amounts, if any,
          after payment by Landlord of all of its costs and expenses actually
          received by Landlord through any reletting of the Premises.

     (4)  Landlord's Bankruptcy Remedies.  Nothing contained in this Lease shall
          limit or prejudice the right of Landlord to prove and obtain as
          liquidated damages in any bankruptcy, insolvency, receivership,
          reorganization or dissolution proceeding, an amount equal to the
          maximum allowable by any statute or rule or law governing such
          proceeding in effect at the time when such damages are to be proved,
          whether or not such amount be greater, equal to or less than the
          amounts recoverable, either as damages or rent under this Lease.

C.        Concurrent or Subsequent Exercise of Remedies . Exercise of any of the
     remedies of Landlord under this Lease shall not prevent the concurrent or
     subsequent exercise of any other remedy provided for in this Lease or
     otherwise available to Landlord at law or in equity.

D.        Choice of Law, Jurisdiction and Venue. This Lease is declared to be a
     Colorado contract, and all of the covenants, conditions and provisions of
     this Lease shall be construed and enforced according to the laws of the
     State of Colorado.  Any action or proceeding against Tenant relating in any
     way to this Lease may be brought and enforced in the District Court in and
     for the City and County of Denver, Colorado, or the United States District
     Court for the District of Colorado, and Tenant irrevocably submits to the
     personal jurisdiction of each such court in respect of any such action or
     proceeding.  Tenant irrevocably appoints its statutory agent for service of
     process, as its agent to receive personal service of process in any such
     action or proceeding.  So long as Tenant has any obligation under this
     Lease, it will maintain a duly appointed agent in Denver, Colorado, for
     personal service of such process and, if it fails to maintain such an
     agent, any such process may be served by serving a copy thereof upon the
     Colorado Secretary of State, by mailing a copy thereof by United States
     Postal Service certified mail addressed to Tenant at its address as
     provided for notices hereunder, or by any other means permitted under the
     rules of federal or state courts in Colorado.  Any judgment so obtained in
     the state or federal courts in Colorado may be enforced and levied upon in
     the courts of any jurisdiction in which Tenant or any of its property may
     be found, and Tenant irrevocably submits to the personal jurisdiction of
     each such court in respect of any such action or proceeding.  Tenant
     irrevocably waives, to the fullest extent permitted by applicable law, any
     objection that it may now or hereafter have to personal jurisdiction or
     venue

                                       30
<PAGE>

     of any such action or proceeding in the District Court in and for the City
     and County of Denver, Colorado, or the United States District Court for the
     District of Colorado, and any claim that any such action or proceeding
     brought in such court has been brought in an inconvenient forum.

25.       EXPENSES OF ENFORCEMENT. Tenant shall pay upon demand all Landlord's
     costs, charges and expenses, together with interest thereon as provided in
     Section 29.B., including the fees and out-of-pocket expenses of attorneys,
     agents and others retained by Landlord, incurred in successfully enforcing
     Tenant's obligations hereunder.  Landlord shall pay upon demand all
     Tenant's costs, charges and expenses, together with interest thereon as
     provided in Section 29.B., including the reasonable fees and out-of-pocket
     expenses of attorneys, agents and others retained by Tenant, incurred in
     successfully enforcing Landlord's obligations hereunder.

26.       COVENANT OF QUIET ENJOYMENT. Landlord covenants that Tenant, on paying
     the Rent, charges for services and other payments herein reserved, and, on
     keeping, observing and performing all the other covenants, conditions, and
     provisions herein contained on the part of Tenant to be kept, observed, and
     performed, shall, during the Term, have quiet and peaceable possession of
     the Premises subject to the covenants, conditions, and provisions hereof,
     and such possession shall not be disturbed by Landlord or by any person
     claiming by, through or under Landlord.

27.       SECURITY DEPOSIT. Tenant hereby deposits with Landlord as the
     "Security Deposit" the amount set forth in Section 1.A.(7) as security for
     the prompt, full and faithful performance by Tenant of each and every
     covenant, condition, and provision of Tenant under this Lease. Landlord
     shall not be required to account for interest or to pay interest to Tenant
     on the Security Deposit.

(1)       If Tenant fails to perform any of its covenants, conditions, or
     provisions hereunder, Landlord may use, apply or retain the whole or any
     part of the Security Deposit for the payment of (i) any Rent or other sums
     of money which Tenant may not have paid when due, (ii) any sum expended by
     Landlord on Tenant's behalf in accordance with the conditions, covenants,
     and provisions of this Lease, or (iii) any sum which Landlord may expend or
     be required to expend by reason of Tenant's default, including, without
     limitation, any damage or deficiency in or from the reletting of the
     Premises as provided in Section 24. The use, application or retention of
     the Security Deposit, or any portion thereof, by Landlord shall not prevent
     Landlord from having or exercising any other right or remedy provided by
     this Lease or by law (it being intended that Landlord shall not first be
     required to proceed against the Security Deposit) and shall not operate as
     a limitation on any recovery to which Landlord may otherwise be entitled.
     Without limiting the generality of the preceding sentence, Landlord shall
     be entitled to any interest elsewhere provided in this Lease
     notwithstanding that Landlord has applied any portion of the Security
     Deposit against the unpaid Rent or other sums against which interest is
     accruing. If any portion of the Security Deposit is used, applied or
     retained by Landlord for the purposes set forth above, Tenant agrees,
     within 10 days after the written demand therefor is made by Landlord, to
     deposit cash with the Landlord in an amount sufficient to restore the
     Security Deposit to its original amount.

(2)       If Tenant shall fully and faithfully comply with all of the
     conditions, covenants, and provisions of this Lease, the Security Deposit,
     or any balance thereof, shall be returned to Tenant without interest within
     60 days after the expiration of the Term or after the date on which Tenant
     vacates the Premises, whichever shall occur last. In the absence of
     evidence

                                       31
<PAGE>

     satisfactory to Landlord of any permitted assignment of the right to
     receive the Security Deposit, or the remaining balance thereof, Landlord
     may return the same to the original Tenant, regardless of one or more
     assignments of Tenant's interest in this Lease or the Security Deposit. In
     such event, upon the return of the Security Deposit, or the remaining
     balance thereof to the original Tenant, Landlord shall be completely
     relieved of liability under this Section 27 or otherwise with respect to
     the Security Deposit.

(3)       Tenant acknowledges that Landlord has the right to transfer its
     interest in the Land, Building, and Complex, and in this Lease and Tenant
     agrees that in the event of any such transfer, Landlord shall have the
     right to transfer the Security Deposit to the transferee. Upon written
     acknowledgment of transferee's receipt of such Security Deposit, Landlord
     shall thereby be released by Tenant from all liability or obligation for
     the return of such Security Deposit and Tenant agrees to look solely to
     such transferee for the return of the Security Deposit.

28.       REAL ESTATE BROKER. The Tenant represents that the Tenant has dealt
     with no broker, real estate person, or finder in connection with this Lease
     other than the broker or brokers, if any, named in Section 1.A.(7) and that
     insofar as the Tenant knows, no other broker, real estate person, or finder
     negotiated this Lease or is entitled to any commission or fee in connection
     herewith. Tenant agrees to indemnify, defend and hold Landlord free and
     harmless from and against all claims for broker's and real estate
     commissions or finder's fees by any person claiming to have been retained
     by, or furnished services to, Tenant in connection with this transaction,
     other than the broker or brokers, if any, named in Section 1.A.(7). No
     commission or fee shall be payable to any broker in connection with any
     renewal of this Lease.

29.       MISCELLANEOUS.

A.        Rights Cumulative. All rights and remedies of the parties under this
Lease shall be cumulative and none shall exclude any other rights and remedies
allowed by law.

B.        Interest. In addition to the rights and remedies under Section 24 or
     elsewhere in this Lease, Tenant covenants and agrees that all Annual Rent,
     Additional Rent, and other Rent and sums due hereunder shall, upon becoming
     due under this Lease and remaining unpaid when due, bear interest from the
     due date until paid at the rate of 18% per annum, compounded monthly, and
     Tenant covenants to pay the same.

C.        Binding Effect. Each of the covenants, conditions, and provisions of
     this Lease shall, as the case may require, extend to and bind or inure to
     the benefit not only of Landlord and Tenant, but also of their respective
     successors or assigns, provided, however, that this clause shall not permit
     any assignment, sublease or other matter by Tenant contrary to the
     provisions of Section 16 hereof. The generality of the foregoing provisions
     of this subsection C. shall not be limited by the use of such words as
     successor landlord or Landlord's successors, assigns, successors in
     interest or transferee in some Sections of this Lease and not in others.

D.        Lease Contains All Terms. All of the representations and obligations
     of the parties are contained herein and no modification, waiver or
     amendment of this Lease or of any of its covenants, conditions or
     provisions shall be binding upon a party unless in writing signed by such
     party.

                                       32
<PAGE>

E.        Delivery for Examination. Submission of the form of the Lease for
     examination shall not bind Landlord in any manner, and no Lease or
     obligations of the Landlord shall arise until this instrument is signed by
     both Landlord and Tenant and delivery is made to each.

F.        No Air Rights. No rights to any view or to light or air over any
     property, whether belonging to Landlord or any other person, are granted to
     Tenant by this Lease.

G.        Modification of Lease. If any present or prospective lender, purchaser
     or lessor requires, as a condition to its lending funds or purchasing an
     interest in the Land or the Building, or entering into a ground or other
     lease covering an interest in the Land or the Building, that certain
     modifications be made to this Lease, which modifications will not require
     Tenant to pay any additional amounts or otherwise change materially the
     rights or obligations of Tenant hereunder, Tenant shall, upon Landlord's
     request, execute appropriate instruments effecting such modifications.

H.        Substitution of Premises.  Intentionally Deleted.

I.        Transfer of Landlord's Interest. Tenant acknowledges that Landlord
     (and each successor landlord) has the right to transfer its interest, by
     reason of this Lease, in any or all of the Land, Building and Complex, and
     Tenant agrees that in the event of any such transfer Landlord (and each
     successor landlord) shall automatically be released from all liability
     under this Lease relating to periods after such respective transfer and
     Tenant agrees to look solely to such respective transferee for the
     performance of the obligations hereunder of Landlord (or such successor
     landlord) relating to periods after such transfer.

J.        Prohibition Against Recording. Neither this Lease, nor any memorandum,
     affidavit or other writing with respect thereto, shall be recorded by
     Tenant or by anyone acting through, under or on behalf of Tenant, and the
     recording thereof in violation of this provision shall make this Lease
     voidable at Landlord's election.

K.        Captions. The captions of Sections and subsections are for convenience
     only and shall not be deemed to limit, construe, affect or alter the
     meaning of such Sections of subsections.

L.        Only Landlord/Tenant Relationship.  Nothing contained in this Lease
     shall be deemed or construed by the parties hereto or by any third party to
     create the relationship of principal and agent, partnership, joint venture
     or any association between Landlord and Tenant, it being expressly
     understood and agreed that neither the method of computation of Rent nor
     any other provisions contained in this Lease nor any act of the parties
     hereto shall be deemed to create any relationship between Landlord and
     Tenant other than the relationship of landlord and tenant. In no event
     shall any fiduciary relationship exist or be implied between Landlord and
     Tenant.

M.        Bills. If Tenant fails to give Landlord specific written notice of its
     objections within 30 days after receipt of any bill or invoice hereunder,
     such bill or invoice shall be deemed true and correct and Tenant may not
     thereafter question the validity of such bill or invoice or the underlying
     information or computations used to determine the amount thereof.

N.        Severability. If any covenant, condition or provision of this Lease
     shall be declared to be void or unenforceable by a final judicial or
     administrative order and if, in

                                       33
<PAGE>

     Landlord's judgment, it was not a material consideration for Landlord's
     execution of this Lease, the Lease shall continue in full force and effect,
     except that the void or unenforceable covenant, condition or provision
     shall be deemed to be deleted from this Lease. If such covenant, condition
     or provision was a material consideration Landlord may terminate this Lease
     on 30 days' prior written notice to Tenant.

O.        Jury Trial. Landlord and Tenant hereby waive trial by jury in any
     action, proceeding or counterclaim brought by Landlord or Tenant against
     the other with respect to the following issues: (i) the insolvency or
     bankruptcy of Landlord or Tenant; (ii) the assignment in whole or in part
     of this Lease by Landlord or Tenant or the subletting of all or any portion
     of the Premises by Tenant; and (iii) the integrity of the Building's
     structural, electrical, or mechanical systems.

P.        Authority to Bind. The individuals signing this Lease on behalf of
     Landlord and Tenant hereby represent and warrant that they are empowered
     and duly authorized to bind the Landlord or the Tenant, as the case may be,
     to this Lease in accordance with its terms.

Q.        Tenant's Covenants Independent. It is the intent of the parties that
     Tenant's covenants, conditions and provisions in this Lease are, and shall
     be construed as independent and not dependent and that all Rent and other
     sums shall be payable without offset, counterclaim, abatement, or reduction
     for any cause except as otherwise specifically provided in this Lease.

R.        Business Days and Hours; Holidays. "Business days" means Monday
     through Friday (except holidays); "normal business hours" means 7:00 a.m.
     to 6:00 p.m. on business days; and "holidays" means those days designated
     as holidays in the Rules and Regulations.

S.        Force Majeure. Except as to the payment of money, when a period of
     time is herein prescribed for action to be taken by either party, neither
     party shall 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 beyond the control of
     the performing party, war, governmental laws, regulations or restrictions
     or any other cause of any kind whatsoever which is beyond the control of
     the performing party. Subject to the preceding sentence, time is of the
     essence of every part of this Lease.

30.       LIMITATIONS ON LANDLORD'S LIABILITY. Any liability of Landlord for
     damages for breach or nonperformance by Landlord, or arising out of the
     subject matter of this Lease or the relationship created hereby, shall be
     collectible only out of Landlord's interest in the Complex and no personal
     liability is assumed by, or may at any time be asserted against, Landlord,
     any parent and affiliated corporations, partnerships, limited liability
     companies, or other entities, its and their partners, venturers, managers,
     principals or other constituents, directors, officers, agents, servants and
     employees, or any of its or their successors or assigns; all such
     liability, if any, being expressly waived and released by Tenant. The
     foregoing sentence is not intended to, and shall not, limit any right that
     Tenant might otherwise have to obtain injunctive relief against Landlord or
     Landlord's successors in interest or any suit or action in connection with
     enforcement or collection of amounts which may become owing or payable
     under or on account of insurance which Landlord or Landlord's successors in
     interest may maintain. If Landlord or Landlord's successor in interest, in
     violation of the terms of this Lease or the provisions of law, withholds,
     denies or delays any consent which Tenant is required to obtain under this
     Lease, Tenant may seek specific performance but shall not be entitled to

                                       34
<PAGE>

     damages therefor.  Landlord's or such successor's review, supervision,
     commenting on or approval of any aspect of work to be done by or for Tenant
     (under the Tenant Construction Agreement, Section 9 hereof, or otherwise)
     are solely for Landlord's or such successor's protection and, except as
     expressly provided in writing by Landlord or such successor after it has
     made or given such review, supervision, comment or approval, create no
     warranties or duties to Tenant or to third parties.

31.       NOTICES. All notices required or permitted under this Lease shall be
     in writing and shall be deemed properly given and received (i) when
     actually given and received at the addresses set out below if delivered in
     person, including delivery by a private courier or overnight delivery
     service; or (ii) three business days after deposit in the United States
     mails, certified or registered mail with return receipt requested, postage
     prepaid, addressed to the party to receive the notice at, in the case of
     notices to Landlord, to Denver Hines Development, LLC, at the Building,
     4600 South Syracuse, Denver, Colorado 80237, Attn: Property Manager, with a

     Houston, Texas 77056-6118, Attn: C. Hastings Johnson, and in the case of
     notices to Tenant, the address set forth in the first paragraph of this
     Lease if such notice is given prior to the Commencement Date and Tenant's
     address at the Premises if such notice is given on or after the
     Commencement Date, or, in either case, at such other address or addresses
     as either party may notify the other of in accordance with the terms
     hereof.

     IN WITNESS WHEREOF, Landlord and Tenant have signed this Lease as of the
date first written above.

                                   Exhibit A
                              4600 SOUTH SYRACUSE
                             ADDITIONAL PROVISIONS

The following additional provisions are attached to and made a part of that
certain Lease Agreement between Denver Hines Development, LLC, as Landlord, and
Tanning Technology Corporation, as Tenant.  In the event of a conflict between
the terms and provisions of the remainder of the Lease and the terms and
provisions of this Exhibit A, the terms and provisions of this Exhibit A shall
control.

1.      Pre-Occupancy Options.  So long as no event of default under this Lease
     has occurred and is continuing at the time that the option may be exercised
     or at the time that any expansion of the Premises becomes applicable as
     provided herein, Tenant shall have the following options (the "Pre-
     Occupancy Options") to expand the initial Premises included within the
     Lease, each of which shall be subject to the terms and conditions of this
     Section 1. On or before January 15, 1999, Tenant may elect, by written
     notice to Landlord, to expand the initial Premises by all, but not less
     than all, of the remainder of Floor 11 of the Building (the "First Pre-
     Occupancy Option"). In addition, if Tenant exercises the First Pre-
     Occupancy Option, then on or before April 1, 1999, Tenant may also elect,
     by written notice to Landlord, to expand the initial Premises by all, but
     not less than all, of Floor 10 of the Building (the "Second Pre-Occupancy
     Option"). The Second Pre-Occupancy Option may be exercised simultaneously
     with the First Pre-Occupancy Option, but the Second Pre-Occupancy Option
     shall expire and be deemed to be of no further force or effect if Tenant
     has not exercised the First Pre-Occupancy Option on or before January 15,
     1999. If Tenant exercises a Pre-Occupancy Option, then the parties shall
     execute an amendment to the Lease, amending the definition of "Premises" to
     include the space added by the exercise of the Pre-Occupancy Option, and
     adjusting the original Rentable Area of the Premises, as defined in the
     Lease, to appropriately include the Rentable Area of the space so added.
     All other terms and conditions of the Lease shall apply to the Premises as
     so expanded.

2.      Options to Renew.  Tenant at its option may renew the term of this Lease
     for two (2) additional terms of five (5) years each (each, a "Renewal
     Option").  Tenant shall give Landlord notice of its intent to renew by
     written notice delivered to Landlord at least eighteen (18) months before
     the expiration of the initial Term of this Lease, and if the first Renewal
     Option has been properly exercised, Tenant shall give Landlord notice of
     its intent to renew for the second renewal Term by written notice delivered
     to Landlord at least eighteen (18) months before the expiration of the
     first renewal Term of this Lease (each, an "Intent Notice"); provided that
     at the time of each Intent Notice and at the commencement of both the first
     and second renewal Terms, no event of default by Tenant as defined in this
     Lease is in existence, and provided further that Tenant furnishes current
     financial statements to Landlord and that no material, adverse change in
     the financial condition of Tenant since May 1, 1998, has occurred.  Upon
     the service of the Intent Notice, Landlord shall within thirty (30) days
     thereafter furnish to Tenant a notice containing the new Annual Rent figure
     for the applicable renewal Term.  The portion of the new Annual Rent figure
     not attributable to Initial Operating Expense Basic Cost payable during
     each renewal Term shall be at ninety-five percent (95%) of the fair market
     rental rate as determined for each renewal Term pursuant to Section 5
     below, and the Annual Rent shall also include a new amount for the Initial
     Operating Expense Basic Cost, which shall be
<PAGE>

     adjusted to reflect the then-current Initial Operating Expense Basic Cost
     figure for the Building. If Tenant does not agree with Landlord's
     determination of the new Annual Rent figure, Tenant shall notify Landlord,
     and the parties shall then proceed to negotiate in good faith concerning
     the new Annual rent figure. If the parties have not agreed upon the new
     Annual Rent amount by the date which is ninety (90) days from the date upon
     which Landlord received Tenant's Intent Notice, then Tenant may notify
     Landlord that it is withdrawing the Intent Notice, and the applicable
     Renewal Option shall be deemed to be no longer available to Tenant or of
     any force or effect. If Tenant fails to withdraw its Intent Notice by the
     date which is ninety (90) days from the date upon which Landlord received
     Tenant's Intent Notice, then Tenant shall be deemed to have exercised the
     applicable Renewal Option, and subject to the conditions set forth in the
     second sentence of this paragraph, this Lease shall be extended by
     execution of an amendment to this Lease incorporating the renewal Term and
     the new Annual Rent rate for the renewal Term, determined as provided
     below. The first renewal Term shall commence upon the expiration date of
     the initial Term of this Lease and expire at midnight of the day prior to
     the annual anniversary of such date five (5) years thereafter, and the
     second renewal Term shall commence upon the expiration date of the first
     renewal Term of this Lease and expire at midnight of the day prior to the
     annual anniversary of such date five (5) years thereafter. Each such
     renewal Term shall include all of the Premises then covered by the Lease,
     and shall be upon the same terms, covenants and conditions as provided in
     this Lease for the initial Term, except that (i) the Annual Rent not
     attributable to Initial Operating Expense Basic Cost payable during each
     renewal Term shall be at the rate initially proposed by Landlord as ninety-
     five percent (95%) of the fair market rental rate as determined for each
     renewal Term pursuant to Section 5 below, unless the parties have agreed
     upon a different rate, in which case the Annual Rent not attributable to
     Initial Operating Expense Basic Cost shall be at the rate agreed, and (ii)
     the Annual Rent shall also include a new amount for the Initial Operating
     Expense Basic Cost, which shall be adjusted to reflect the then-current
     Initial Operating Expense Basic Cost figure for the Building, and
     thereafter Tenant shall pay all Additional Rent applicable to the Expansion
     Space, and Annual Rent shall be increased, adjusted, or augmented as
     provided in and under this Lease, and (iii) Landlord shall provide a tenant
     improvement allowance at the commencement of the first Renewal Term of
     $10.00 per square foot of Rentable Area included within the Premises, and
     at the commencement of the second Renewal Term of $12.50 per square foot of
     Rentable Area included within the Premises. Payment of all Additional Rent
     and any other Rent required to be paid by Tenant as provided in this Lease
     for the initial Term shall continue to be made during the renewal Terms.
     Any termination of this Lease, any assignment of this Lease and/or any
     subletting of the Premises terminates the Renewal Options, except in the
     case of an assignment or sublease by Tenant to an entity controlling,
     controlled by, or under common control with Tenant, or to any firm or
     company into or within which Tenant may be merged or consolidated, or which
     purchases all or substantially all of the assets or stock of Tenant.

3.      Expansion Options.  So long as no event of default under this Lease has
     occurred and is continuing at the time that the option may be exercised or
     at the time that any expansion of the Premises becomes applicable as
     provided herein, Tenant shall have the following two (2)  options (the
     "Expansion Options") to expand the Premises, each of which shall be subject
     to the terms and conditions of this Section 3:

                                     A-2
<PAGE>

A.      The first Expansion Option shall be available to Tenant only if Tenant
     has not exercised its Pre-Occupancy Option to add the balance of Floor 11
     of the Building to the initial Premises. The first Expansion Option, if
     exercised, will be applicable to all of the remainder of Floor 11 of the
     Building which was not included within the initial Premises (the "First
     Expansion Space"). If the first Expansion Option is exercised, the First
     Expansion Space will be delivered by Landlord to Tenant for the purpose of
     commencing its tenant finish work therein on a date to be designated by
     Landlord, which shall be between the date which is three (3) years from the
     Commencement Date and the date which is four (4) years from the
     Commencement Date (the "First Occupancy Date").

B.      The second Expansion Option shall be available to Tenant only (i) if
     Tenant has not exercised its Pre-Occupancy Option to add Floor 10 of the
     Building to the initial Premises, (ii) if Tenant has previously exercised
     the first Expansion Option, and (iii) if Tenant has previously exercised
     its first Renewal Option to extend the Term by an additional five (5)
     years. The second Expansion Option, if exercised, will be applicable to all
     of Floor 10 of the Building (the "Second Expansion Space"). If the second
     Expansion Option is exercised, the Second Expansion Space will be delivered
     by Landlord to Tenant for the purpose of commencing its tenant finish work
     therein on a date to be designated by Landlord, which shall be between the
     date which is five (5) years from the Commencement Date and the date which
     is six (6) years from the Commencement Date (the "Second Occupancy Date").

C.      If the first Expansion Option is available to Tenant as set forth above,
     Landlord shall notify Tenant of the First Occupancy Date at least twelve
     (12) months prior thereto, and if the second Expansion Option is available
     to Tenant as set forth above, Landlord shall then notify Tenant of the
     Second Occupancy Date at least twelve (12) months prior thereto (each, an
     "Occupancy Notice"). Each Occupancy Notice shall also contain the fair
     market rental rate, determined in accordance with Section 5 below, which
     will be applicable to the Expansion Space.

D.      In order to exercise either Expansion Option, Tenant shall be required
     to give Landlord written notice of exercise (the "Exercise Notice") within
     thirty (30) days after the date upon which Tenant receives the applicable
     Occupancy Notice. If Tenant gives Landlord a timely Exercise Notice, the
     applicable Expansion Space shall be added to the Premises as of the
     Occupancy Date for such Expansion Option. If Tenant gives Landlord notice
     that Tenant has elected not to exercise any Expansion Option or gives no
     notice to Landlord within such 30-day period, Tenant shall have irrevocably
     determined not to exercise such Expansion Option and such Expansion Option
     shall have been relinquished.

E.      Landlord shall make each Expansion Space available to Tenant for
     purposes of making Tenant's improvements therein on the Occupancy Date for
     such Expansion Space. Tenant's improvements in the Expansion Space shall be
     constructed in accordance with and subject to all of the terms and
     conditions of this Lease.

F.      The portion of Annual Rent not attributable to Initial Operating Expense
     Basic Cost payable with respect to any Expansion Space shall be the fair
     market rental rate for such Expansion Space.  The Annual Rent shall also
     include a new amount for the Initial Operating Expense Basic Cost, which
     shall be adjusted to reflect the then-current Initial Operating Expense
     Basic Cost figure for the Building, and thereafter Tenant shall pay all
     Additional Rent

                                     A-3
<PAGE>

     applicable to the Expansion Space, and Annual Rent shall be increased,
     adjusted, or augmented as provided in and under this Lease. Rent shall
     commence for any Expansion Space on the date which is ninety (90) days from
     the applicable Occupancy Date.

G.        All other terms of this Lease shall be applicable to the Expansion
     Space and Tenant's occupancy thereof from the time that Tenant takes
     occupancy thereof to construct its improvements in the Expansion Space.

4.        Rights of First Offer.

A.        If the Pre-Occupancy Offer expires on January 15, 1999, without
     exercise by Tenant, then so long as Tenant is not in default in the
     performance of any of its covenants under the Lease, Tenant is hereby
     granted a right of first offer (the "Initial Right of First Offer") to
     lease space on Floors 9, 10 or 11 of the Building (each an "Initial First
     Offer Space"), during the initial leasing of the Building by Landlord, in
     accordance with, and subject to, the following terms and conditions:

        (1)  On January 16, 1999, and every four (4) months thereafter until all
             of Floors 9, 10 and 11 have been initially leased, Landlord shall
             notify Tenant in writing of the Initial First Offer Space which is
             then available for leasing (which as used throughout this Section
             4, shall mean that Landlord is prepared to make a written proposal
             to a bona fide prospective third party tenant to lease the space),
             including the following:

             i) The specific location of each Initial First Offer Space, the
                approximate Rentable Area comprising each Initial First Offer
                Space, and the configuration or configurations in which Landlord
                is offering to lease such Initial First Offer Space; and

            ii) The Annual Rent at which Landlord is offering each Initial First
                Offer Space, and the portion of such Annual Rent which is
                attributable to the Initial Operating Expense Basic Cost; and

           iii) Such improvements, if any, as Landlord is willing to make to
                each Initial First Offer Space, or such improvement allowance,
                if any, as Landlord is willing to provide in connection with a
                lease of such Initial First Offer Space.

     (2)  Within ten (10) business days after Tenant's receipt of Landlord's
          notice, Tenant shall notify Landlord in writing of Tenant's election
          concerning exercise of the Initial Right of First Offer.  Tenant may
          lease any space which is offered as a Initial First Offer Space by
          Landlord, but Tenant shall not be entitled to lease less than all of
          any Initial First Offer Space in the configuration in which it is
          offered by Landlord.  If Tenant exercises the Initial Right of First
          Offer as to any Initial First Offer Space, then the leasing of such
          Initial First Offer Space shall be on the same terms and conditions as
          set forth in the Lease except as follows:

                                     A-4
<PAGE>

          i)   The Annual Rent, including the Initial Operating Expense Basic
               Cost, to be paid for all the Initial First Offer Space shall be
               at the rates offered by Landlord in its notice of availability.
               Tenant shall also pay all Additional Rent and other Rent or
               charges applicable to the Initial First Offer Space.

          ii)  Tenant's obligation to pay rent for the Initial First Offer Space
               shall commence on the Commencement Date of the Lease, and shall
               continue through the expiration or earlier termination of the
               Term of the Lease.

          iii) Landlord shall deliver and Tenant shall accept the Initial First
               Offer Space in its then existing condition, on an "as is" basis,
               and Tenant shall not be entitled to receive any contribution or
               allowance from Landlord for improvement thereof, except as
               provided above in Paragraph A(1)(iii).

          iv)  The original Rentable Area of the Premises, as defined in the
               Lease, shall be adjusted appropriately to include the Rentable
               Area of the Initial First Offer Space and Landlord and Tenant
               shall execute an amendment to the Lease, incorporating the
               Initial First Offer Space and reflecting the terms and provisions
               set forth herein as applicable thereto.

     (3)  If Tenant does not exercise the Initial Right of First Offer as to a
          Initial First Offer Space strictly in accordance with this Section,
          the time provisions hereof being of the essence, the Initial Right of
          First Offer shall cease to exist as to that Initial First Offer Space,
          and Landlord shall be free to lease that Initial First Offer Space on
          such terms as Landlord may determine and without any restrictions by
          reason of the Lease or this Initial Right of First Offer, so long as
          the Annual Rent received by Landlord is not less than ninety percent
          (90%) of the rates at which such Initial First Offer Spaces were
          offered by Landlord in its latest notice of availability.

B.        After the initial leasing of Floors 9, 10 and 11 is complete, then so
     long as Tenant is not in default in the performance of any of its covenants
     under the Lease, Tenant is hereby granted an ongoing right of first offer
     (the "Subsequent Right of First Offer", and the Initial Right of First
     Offer and the Subsequent Right of First Offer are sometimes collectively
     referred to as the "Rights of First Offer") to lease all, but not less than
     all, of any space on Floors 9, 10 or 11 of the Building (each a "Subsequent
     First Offer Space", and the Initial First Offer Space and Subsequent First
     Offer Space are sometimes collectively referred to as the "First Offer
     Space") which was not initially leased by Tenant, if the same becomes
     available by reason of the expiration or earlier termination of any third-
     party lease thereof which is in effect. Tenant's right to each respective
     Subsequent First Offer Space is subject to the rights of any tenants under
     any leases to a third party hereafter entered into, of any space in the
     Building ("third party leases"), including any options to lease, rights of
     expansion, rights of first refusal, or other options or rights of any
     tenants ("third party rights") (but not including a right of first offer,
     which

                                     A-5
<PAGE>

applies only to the above Subsequent First Offer Spaces, in a lease hereafter
executed) under any third party leases.

     The Subsequent Right of First Offer shall be exercised in accordance with,
and subject to, the following terms and conditions:

     (1)  Landlord shall notify Tenant in writing of the Subsequent First Offer
          Space if the same has or will become available, including the
          following:

          i)   The specific location of the Subsequent First Offer Space and the
               exact Rentable Area comprising the Subsequent First Offer Space;
               and

          ii)  The Annual Rent at which Landlord is offering each Subsequent
               First Offer Space, and the portion of such Annual Rent which is
               attributable to the Initial Operating Expense Basic Cost; and

          iii) The approximate date on which the Subsequent First Offer Space
               will become available for leasing to Tenant; and

          iv)  A description of all third party leases and all third party
               rights, if any, which affect the Subsequent First Offer Space;
               and

          v)   Such improvements, if any, as Landlord is willing to make to the
               Subsequent First Offer Space, or such improvement allowance, if
               any, as Landlord is willing to provide in connection with a lease
               of such Subsequent First Offer Space.

     (2)  Within ten (10) business days after Tenant's receipt of Landlord's
          notice, Tenant shall notify Landlord in writing of Tenant's election
          concerning exercise of the Subsequent Right of First Offer.  If Tenant
          exercises the Subsequent Right of First Offer, then the leasing of the
          Subsequent First Offer Space shall be on the same terms and conditions
          as set forth in the Lease, except as follows:

          i)   The Annual Rent, including the Initial Operating Expense Basic
               Cost, to be paid for the Subsequent First Offer Space shall be at
               the rate offered by Landlord in its notice of availability.
               Tenant shall also pay all Additional Rent and other Rent or
               charges applicable to the Subsequent First Offer Space.

          ii)  Tenant's obligation to pay rent for the Subsequent First Offer
               Space shall commence on the date such space is made available to
               Tenant, but not sooner than the date specified in Landlord's
               notice unless Tenant occupies the space prior to such date, and
               shall continue through the expiration or earlier termination

                                     A-6
<PAGE>

               of the term of the Lease, except, however, as provided in
               Paragraph B(2)(v) below.

          iii) Landlord shall deliver and Tenant shall accept the Subsequent
               First Offer Space in its then existing condition, on an "as is"
               basis, and Tenant shall not be entitled to receive any
               contribution or allowance from Landlord for improvement thereof,
               except as provided above in Paragraph B(1)(v).

          iv)  The original Rentable Area of the Premises, as defined in the
               Lease, shall be adjusted appropriately to include the Rentable
               Area of the Subsequent First Offer Space and Landlord and Tenant
               shall execute, at the request of either, an instrument
               delineating and describing the Rentable Area, as so adjusted.

          v)   Tenant's right to occupy the Subsequent First Offer Space shall
               continue to and end at the same time as its right to occupy the
               original Premises, except in any instance in which the Subsequent
               First Offer Space by reason of third-party leases or third-party
               rights, must be made available to a third party, in which event
               Tenant's right to occupy the Subsequent First Offer Space shall
               end when necessary, in Landlord's determination, in order to make
               it available to such third party.

     (3)  If Tenant does not exercise the Subsequent Right of First Offer as to
          a Subsequent First Offer Space strictly in accordance with this
          Paragraph, the time provisions thereof being of the essence, the
          Subsequent Right of First Offer shall cease to exist as to that
          Subsequent First Offer Space and Landlord shall be free to lease that
          Subsequent First Offer Space on such terms as Landlord may determine
          and without any restrictions by reason of the Lease or this Subsequent
          Right of First Offer, so long as the Annual Rent received by Landlord
          is not less than ninety percent (90%) of the rates at which such
          Subsequent First Offer Space was offered by Landlord in its notice of
          availability.

C.        Tenant may not assign its Rights of First Offer, or any rights
     thereunder, to any subtenant of the original Premises, or to any assignee
     of the Lease, or to any other person, except in the case of an assignment
     or sublease by Tenant to an entity controlling, controlled by, or under
     common control with Tenant, or to any firm or company into or within which
     Tenant may be merged or consolidated, or which purchases all or
     substantially all of the assets or stock of Tenant; provided, however, that
     if the Tenant has exercised a Right of First Offer and has leased a First
     Offer Space, then thereafter Tenant's right to sublease that First Offer
     Space, or to assign its rights under the Lease to that First Offer Space,
     shall be determined in combination with the original Premises under the
     Lease. Any Right of First Offer, which has not theretofore both been
     exercised by Tenant and under which Tenant has leased the First Offer
     Space, shall expire upon any assignment of the Lease.

                                     A-7
<PAGE>

D.      Upon inclusion, under the Lease, of a First Offer Space with the
     original Premises, all references in the Lease to the "Premises" shall be
     deemed to include that First Offer Space.

5.      Definition of Fair Market Rental Rate. The "fair market rental rate," as
     such term is used in this Lease, shall mean and refer to the prevailing
     rental rate (exclusive of Operating Expenses, Taxes and other such costs)
     per square foot of Rentable Area then being offered by landlords to tenants
     of similar size for comparable space in buildings in the Denver
     Technological Center comparable to the Building. In determining the fair
     market rental rate, Landlord shall take into consideration the rental rates
     per square foot of Rentable Area then being obtained in the Building, with
     appropriate adjustment for floor location within the Building, whether such
     other lease is a new lease or a renewal lease, the date of signing and the
     term of any such other leases, rent concessions, tenant finish allowances
     and credits provided to such other tenants, the amount of space leased, the
     creditworthiness of the tenants, moving concessions, commissions and any
     other matter that a reasonably prudent tenant and landlord would consider
     in the determination of rent and similar items. In addition, Landlord will
     take into account the existing condition of the subject space and its
     suitability for Tenant's use, and any improvements to be made thereto by
     Landlord.

6.      Additional Parking.  If Tenant wishes to increase its right to take and
     obligation to pay for additional parking spaces in connection with its
     exercise of a Pre-Occupancy Option, an Expansion Option, or a Right of
     First Offer, it must so elect in its notice to Landlord of its exercise of
     Option or Right.  Tenant's right to take and obligation to pay for such
     additional parking spaces shall be as set out in Exhibit F to the Lease,
     except as set out below in this Paragraph 6.  All of such additional
     parking spaces shall be on an unassigned basis, and the monthly rent due
     therefore shall be the then-current rate charged by the operator of the
     garage or parking lot, with no maximum guaranteed rate.  The location of
     such parking spaces in the garage or surface lot shall be designated in
     Landlord's sole discretion, and the number of such parking spaces to which
     Tenant shall be entitled shall be based on Landlord's parking formula in
     effect on the date of Tenant's above notice to Landlord.

7.      Building Name.  Until the exercise of a Pre-Occupancy Option by Tenant
     which results in the initial Premises included within the Lease containing
     at least 75,000 square feet of Rentable Area, Landlord may grant the right
     to initially name the Building to any other tenant in the Building which
     leases more space than Tenant within the Building.  In the event that
     Tenant exercises a Pre-Occupancy Option, so that the initial Premises
     included within the Lease contain at least 75,000 square feet of Rentable
     Area, and if at that time Landlord has not yet granted to any other tenant
     the right to initially name the Building, then subject to the provisions of
     the next sentence, Tenant shall have the right to initially name the
     Building, subject to Landlord's reasonable approval of the name selected by
     Tenant.  However, at any time that any other tenant in the Building leases
     at least 25,000 square feet of Rentable Area in the Building more than the
     number of square feet of Rentable Area then included within the Premises,
     Landlord shall have the right to grant to such other tenant the right to
     name the Building, and the right granted to Tenant in this paragraph to
     name the Building shall then cease to exist.

8.      Signage.  Tenant shall not install, place, inscribe, paint or otherwise
     attach and shall not permit any sign, advertisement, notice, marquee or
     awning on any part of the outside of the Premises (including any portion of
     the Premises fronting on any interior corridor or lobby)

                                     A-8
<PAGE>

     or on any part of the Building (including the outside walls and the roof),
     without the prior written consent of Landlord in each instance; provided,
     however, that Tenant shall have the right, at its sole cost, to install (i)
     signs on the inside of the Premises so long as such signage is not visible
     from the common corridors or other common areas, and (ii) a single sign
     identifying Tenant outside of the Building, at a location and in a size and
     design approved by Landlord. Any permitted sign shall also comply with the
     requirements of the Denver Technological Center Architectural Control
     Committee and of any governmental or quasi-governmental authority having
     jurisdiction over the Building, and Tenant is solely responsible for such
     compliance. Tenant shall, at its own expense, maintain in first-class
     condition all permitted signs and shall, on the expiration or termination
     of this Lease, and at its own expense, remove all such permitted signs and
     repair any damage caused by such removal. Landlord shall have the right to
     remove all nonpermitted signs without notice to Tenant and at the expense
     of Tenant.

9.      Satellite Dish.  Provided the Lease shall be in full force and effect
     and no Event of Default exists thereunder, Tenant may, at its sole cost and
     expense, install and operate a satellite dish or microwave antenna no
     larger than six feet (6') in diameter (referred to herein as the "satellite
     dish") and surrounding screening on the roof of the Building, subject to
     Landlord's approval of the location of the dish and the design of the
     screening surrounding the dish. The installation of the satellite dish
     shall be subject to the following:

        (1)  Tenant shall, at all times, and at its sole cost and expense,
             comply with all applicable governmental and quasi-governmental
             regulations, and obtain and maintain any and all required
             governmental and quasi-governmental permits, licenses,
             authorizations and approvals, including without limitation any
             necessary approvals of the Denver Technological Center
             Architectural Control Committee;

        (2)  Tenant shall maintain adequate liability insurance covering the
             installation and operation of the satellite dish in which Landlord
             is named as an additional insured, and proof of which shall be
             provided to Landlord prior to installation; and

        (3)  Tenant shall, at its sole cost and expense, maintain the satellite
             dish in good working order and do so in a manner such that the
             operation of the satellite dish does not cause any interference
             with any telecommunications, mechanical or other system located in
             or servicing the Building, whether such system belongs to and is
             utilized by Landlord or any other tenant in the Building.

B.      Tenant covenants and agrees that the installation, operation and removal
     of the satellite dish will be at its sole risk. Tenant agrees to indemnify
     and defend Landlord against all claims, actions, damages, liabilities and
     expenses including reasonable attorney's fees and disbursements in
     connection with the loss of life, personal injury, damage to property or
     business or any other loss or injury or as a result of any litigation
     arising out of the installation, operation or removal of the satellite
     dish.

C.      At the expiration or sooner termination of the Lease, or upon
     termination of the operation of the satellite dish, or revocation of a
     required license issued, Tenant shall, at its sole cost and expense, remove
     the satellite dish from the Building and repair the installation area to
     the same condition as existed prior to such installation. If Tenant does
     not remove the satellite dish and repair such area when so required, Tenant
     hereby authorizes Landlord to remove and

                                     A-9
<PAGE>

     dispose of the satellite dish and repair the installation area and to
     charge Tenant for all costs and expenses incurred in so doing.

<PAGE>

3.      Building Standard.  Unless Landlord has given its consent to a different
        -----------------
     finish item in connection with its approval of the Tenant Space Plan or the
     Tenant Working Drawings, Tenant must use the Building Standard items
     prescribed by Landlord for lights, ceilings, window coverings, and any
     other finish item which is visible from the exterior of the Building, in
     order to assure the consistent quality and appearance of the Building.

4.      Landlord Work and Tenant Extra Work
        -----------------------------------

A.      Landlord will complete the Base Building Shell at Landlord's sole cost
     and expense. For all of the improvements to be made to the Premises beyond
     the Base Building Shell, Landlord will pay as much as the Space Planning
     Allowance for the costs of preparing the Tenant Space Plan, and as much as
     the Design and Construction Allowance for the costs of preparing the Tenant
     Working Drawings, and for the initial construction of Tenant's improvements
     in the Premises (including without limitation all permits, taxes, and
     architectural, engineering and construction contractor's fees associated
     with the construction) (collectively, "Tenant Work"), less an amount
     payable to Landlord for its coordination and review of the Tenant Work
     equal to five percent (5%) of the cost of the Tenant Work; provided,
     however, that if the Tenant Work is performed in connection with the
     completion of the Base Building Shell such amount shall not be charged by
     Landlord. If any amount of the Tenant Finish Allowance is not used in
     connection with the Tenant Work, the unused portion will be credited by
     Landlord against those portions of the first payments of Annual Rent which
     are due under the Lease which are not attributable to the Initial Operating
     Expense Basic Cost.

B.      Tenant will pay for the costs of all Tenant Extra Work (including
     without limitation permits, taxes, and all space planning, architectural,
     engineering and construction contractor's fees associated with the Tenant
     Extra Work, and, unless waived as provided above, the cost of Landlord's
     overhead for coordination and administration at the rate of five percent
     (5%) of the total cost to Landlord of all Tenant Extra Work). All requested
     Tenant Extra Work will be subject to Landlord's prior written approval in
     accordance with paragraph 5.

5.      Landlord's Approval.  Landlord, in its sole discretion, may withhold its
        -------------------
     approval of any Tenant Space Plan, Tenant Working Drawings, Tenant Extra
     Work or Change Orders which require work which:

A.      Exceeds or affects the structural integrity of the Building, or any part
     of the heating, ventilating, air conditioning, plumbing, mechanical,
     electrical, communication or other systems of the Building;

B.      Is not approved by the holder of any mortgage or deed of trust
encumbering the Building at the time the work is proposed;

C.      Would not be approved by a prudent owner of property similar to the
Building (i.e., a Class A office building in the Denver Technological Center);

D.      Violates any agreement which affects the Building or binds Landlord;

E.      Landlord reasonably believes will increase the cost of operation or
maintenance of any of the systems of the Building;

                                      D-2
<PAGE>

F.      Landlord reasonably believes will reduce the market value of the
Premises or the Building at the end of the Term;

G.      Does not conform to applicable building code or is not approved by any
governmental authority with jurisdiction over the Premises; or

H.   Unless Landlord has given its consent to a different finish item in
     connection with its approval of the Tenant Space Plan or the Tenant Working
     Drawings, does not conform to the Building Standard for lights, ceilings,
     window coverings, or any other finish item which is visible from the
     exterior of the Building, or which is not compatible with the finish level
     of a Class A office building.

6.        Schedule of Tenant Improvement Activities
          -----------------------------------------

A.        Landlord shall provide written notice to Tenant of the date on which
     the Tenant Information (as defined in the next sentence) must be submitted
     to Landlord (the "Submission Date"), at least sixty (60) days prior to the
     Submission Date. On or before the Submission Date, Tenant will cooperate
     with and submit to Landlord the information (the "Tenant Information")
     necessary for Landlord's architect or space planner to prepare a space
     layout and improvement plan for the Premises (the "Tenant Space Plan").
     Landlord will promptly prepare a preliminary estimate of the cost of
     preparing the Tenant's Space Plan (the "Tenant's Estimated Space Planning
     Cost"), based on the Tenant Information. If the Tenant's Estimated Space
     Planning Cost is more than the Space Planning Allowance, Landlord will so
     notify Tenant in writing and Tenant will either:

        (1)  Agree in writing to pay the amount by which the Tenant's Space
             Planning Cost exceeds the Space Planning Allowance as though that
             amount were Tenant Extra Work subject to paragraph 7, or

        (2)  Revise the Tenant Information in order to assure that the Tenant's
             Estimated Space Planning Cost is either (A) no more than the Space
             Planning Allowance or (B) in excess of the Space Planning Allowance
             by an amount which Tenant agrees to pay pursuant to clause (1)
             immediately above.

     Each day from the date which is five (5) days following Tenant's receipt of
the Tenant's Estimated Space Planning Cost until the fulfillment of Tenant's
obligations in either clause (1) or clause (2) immediately above will be a day
of Tenant's delay.  Upon Tenant's fulfillment of its obligations in either
clause (1) or clause (2) immediately above, the Tenant's Estimated Space
Planning Cost will be deemed approved.  If the Tenant's Estimated Space Planning
Cost is less than the Space Planning Allowance, the Tenant's Estimated Space
Planning Cost will be deemed approved without notice to Tenant.

B.           After approval of the Tenant's Estimated Space Planning Cost,
     Landlord will cause to be prepared and delivered to Tenant the proposed
     Tenant Space Plan. Within five (5) days after its receipt of the proposed
     Tenant Space Plan, Tenant will give Landlord written notice whether or not
     Tenant approves the proposed Tenant Space Plan. If Tenant fails to give
     Landlord that notice by that fifth day, then, in addition to any other
     rights which it may have on account of that failure, Landlord may consider
     each day following that fifth day until its receipt of

                                      D-3
<PAGE>

     Tenant's notice to be a day of delay by Tenant. If Tenant's notice objects
     to the proposed Tenant Space Plan, the notice will set forth how the
     proposed Tenant Space Plan is inconsistent with the Tenant Information and
     how the Proposed Tenant Space Plan must be changed in order to overcome
     Tenant's objections. Landlord will submit a revised Tenant Space Plan to
     Tenant.

        The revised Tenant Space Plan, and any revisions to it, will be treated
as though they were the first proposed Tenant Space Plan prepared pursuant to
this paragraph. If the proposed Tenant Space Plan, or any revision to it, is not
inconsistent with the Tenant Information, then each day following Landlord's
receipt of Tenant's objections until Landlord's receipt of Tenant's approval of
a Tenant Space Plan will be a day of Tenant's delay.

C.        After approval of the Tenant Space Plan, Landlord will promptly
     prepare a preliminary estimate of the cost of Tenant's improvements,
     including without limitation permits, taxes, and all architectural,
     engineering and construction contractor's fees associated therewith (the
     "Tenant's Estimated Construction Cost"), as set forth in the Tenant Space
     Plan. If the Tenant's Estimated Construction Cost is more than the
     Construction Allowance, Landlord will so notify Tenant in writing and
     Tenant will either:

     (1)  Agree in writing to pay the amount by which the Tenant's Estimated
          Construction Cost exceeds the Construction Allowance as though that
          amount were Tenant Extra Work subject to paragraph 7, or

     (2)  Revise the Tenant Space Plan in order to assure that the Tenant's
          Estimated Construction Cost is either (A) no more than the
          Construction Allowance or (B) in excess of the Construction Allowance
          by an amount which Tenant agrees to pay pursuant to clause (1)
          immediately above.

     Each day from the date which is five (5) days following Tenant's receipt of
the Tenant's Estimated Construction Cost until the fulfillment of Tenant's
obligations in either clause (1) or clause (2) immediately above will be a day
of Tenant's delay.  Upon Tenant's fulfillment of its obligations in either
clause (1) or clause (2) immediately above, the Tenant's Estimated Construction
Cost will be deemed approved.  If the Tenant's Estimated Construction Cost is
less than the Construction Allowance, the Tenant's Estimated Construction Cost
will be deemed approved without notice to Tenant.

D.        After approval of the Tenant's Estimated Construction Cost, Landlord
     will cause to be prepared and delivered to Tenant working drawings for the
     Premises ("Tenant Working Drawings"), an estimated construction schedule
     (the "Construction Schedule"), and a cost proposal (the "Tenant Cost
     Proposal") for construction of Tenant's improvements in accordance with
     Tenant Working Drawings. The Construction Schedule will set forth time
     frames for approval. If the Tenant Cost Proposal is less than the sum of
     the Construction Allowance and any amount in excess of the Construction
     Allowance which Tenant has agreed to pay pursuant to paragraph 6.C,
     Landlord will take steps necessary to complete construction of the
     improvements to the Premises. If the Tenant Cost Proposal is more than the
     sum of the Construction Allowance plus any amount which Tenant has agreed
     to pay pursuant to clause (1) of paragraph 6.C immediately above (such
     greater amount, the "Maximum Approved Cost"), Landlord will so notify
     Tenant in writing and Tenant will either (1) agree in writing to pay the

                                      D-4
<PAGE>

     amount by which the Tenant Cost Proposal exceeds the Maximum Approved Cost
     as though that additional amount were Tenant Extra Work subject to
     paragraph 7 or (2) revise the Tenant Working Drawings in order to assure
     that the Tenant Cost Proposal is no more than the Maximum Approved Cost.
     Each day from the date which is five (5) days following Tenant's receipt of
     the Tenant's Cost Proposal until the fulfillment of Tenant's obligations in
     either clause (1) or clause (2) immediately above will be a day of Tenant's
     delay.  Upon Tenant's fulfillment of its obligations under either clause
     (1) or clause (2) immediately above, Landlord will take steps necessary to
     complete construction of the improvements to the Premises.

E.        All work will be performed by one or more contractors selected and
     engaged by Landlord, after a competitive bidding process in which Landlord
     shall obtain bids from at least three (3) qualified contractors. Tenant
     will have the right to designate a subcontractor for each component of work
     which is to be performed by a subcontractor. Landlord will not unreasonably
     withhold its consent to solicitation of bids from the subcontractors
     designated by Tenant, provided such subcontractors meet Landlord's
     requirements for subcontractors, and provided further that any component of
     work affecting the life safety, mechanical, electrical or plumbing systems
     of the Building must be performed by the approved Building subcontractor
     for that work. Following approval of the Tenant 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 and subject to
     receipt of the payment required under paragraph 7, Landlord will begin
     construction.

7.        Payment for Tenant Extra Work.  Tenant will pay to Landlord, in
          -----------------------------
     advance, the total amount payable by Tenant for Tenant Extra Work, subject
     to Tenant's right to withhold retainage of ten percent with respect to all
     Tenant Extra Work until completion of the items shown on the punch-list
     described in Paragraph 10.A below, following which completion final payment
     of the retainage amounts shall be promptly made by Tenant.

8.        Change Orders.  Tenant may authorize changes in the work 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 (the "Change Order") setting forth the
     total cost of such change and its impact on the Construction Schedule,
     which will include associated architectural, engineering and construction
     contractor's fees, and, unless waived as provided above, the cost of
     Landlord's overhead at the rate of five percent (5%) of the amount of the
     Change Order.  If Tenant fails to approve and pay for such Change Order
     within five (5) 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 and payment,
     Landlord will proceed to perform the change.

9.        Completion and Commencement Date.  Subject to the provisions of
          --------------------------------
     Section 5.C of the Lease and the other provisions of this Tenant
     Construction Agreement, Landlord shall substantially complete the Tenant
     Work in the Premises and tender the Premises to Tenant on or before August
     1, 1999. Subject to the provisions of Section 3.A of the Lease concerning
     abatement, Tenant's obligation for payment of Rent pursuant to the Lease
     will commence on the Commencement Date; however, the Commencement Date and
     the date for the payment of

                                      D-5
<PAGE>

     Rent shall be delayed on a day-to-day basis for each day the substantial
     completion of the Tenant Work is delayed by Landlord or its contractors or
     agents. The date of substantial completion shall mean the day on which the
     Tenant Work has been completed in accordance with the Tenant Working
     Drawings so that Tenant may receive the beneficial use of the Premises
     (i.e., when Tenant may use the Premises for their intended purpose),
     subject to the punch list of items referred to below. 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.        Change Orders requested by Tenant;

B.        Delays in obtaining non-Building Standard construction materials
requested by Tenant;

C.        Tenant's failure to approve timely any item requiring Tenant's
approval; and

D.        Delays by Tenant according to paragraph 6.

     In the event that substantial completion of the Tenant Work is delayed by
Landlord, its contractors or agents, the Commencement Date will be the date of
substantial completion of the Tenant Work, subject only to the completion of
Landlord's punch-list items (that is, those items which 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 1(A)(1) of the
Lease.

10.       Condition of the Premises.
          -------------------------

A.        Prior to the Commencement Date, Tenant will 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 Tenant
     Construction Agreement 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 Tenant Construction Agreement.
     If Tenant fails to submit a punch-list to Landlord prior to 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 30 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 or the failure of Landlord's contractor to construct
     the improvements in a good

                                      D-6
<PAGE>

     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 the period of time
     covered by the contractor's warranty under the construction contract (which
     shall be no less than 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 10, Landlord will have
     no obligation or liability to Tenant for latent defects.

11.       Adjustments Upon Completion.  As soon as practicable, upon
          ---------------------------
     completion of the Tenant's Space Plan, Landlord will notify Tenant of the
     Rentable Area of the Premises, and if such Rentable Area is different from
     that stated in Section 1(A)(5) of the Lease, the actual Annual Rent shall
     be modified accordingly. Tenant, within ten (10) days of Landlord's written
     request, will execute a certificate confirming such information.

12.       Defaults.  Failure by Tenant to comply with any of its obligations
          --------
     under Paragraph 7 of this Exhibit D shall constitute an Event of Default
                               ---------
     under the terms of the Lease, and Landlord shall then be entitled to the
     benefit of all of the remedies provided for in the Lease.

all keys, cards and passes for offices, rooms, parking areas and toilet rooms
which shall have been furnished to Tenant.  In the event of the loss of any
keys, cards, or passes so furnished, Tenant shall pay Landlord therefor.  Except
as permitted in Section 22 (4) of the Lease, Tenant shall not make, or cause to

shall pay Landlord for any additional such keys over and above the two sets of
keys furnished by Landlord.

11.       Tenant shall not install linoleum, tile, carpet or other floor

                              4600 SOUTH SYRACUSE

                                    PARKING

Subject to the following provisions, during the Term of this Lease, Landlord
agrees to permit Tenant the use of, and Tenant agrees to pay the amounts
described herein for the use of, 200 parking spaces in the Complex for the
parking of vehicles.  Of those 200 spaces, 150 shall be located in the parking
garage of the Complex.  Of the spaces in the parking garage, up to 30 may be
assigned parking spaces, and the remainder shall be unassigned parking spaces.
Tenant shall designate, in a written notice to Landlord delivered at least six
months prior to the Commencement Date, how many of the spaces located in the
parking garage are initially to be assigned, based on the parameters of the
preceding sentence.  Subject to the provisions of the next sentence, all of the
remaining 50 spaces shall be unassigned parking spaces on the surface parking
lot.  Tenant shall owe no monthly rent for any of the parking spaces provided
hereunder for the first eighteen months of the Term.  Beginning with the
nineteenth (19th) month of the Term, Tenant's initial obligation to pay monthly
rent shall be $65.00 per month for each assigned space in the parking garage and
$35.00 per month for each unassigned space in the parking garage; provided,
however, that such amounts may be increased by Landlord during the Term to the
then-current rates charged from time to time by the operator of the parking
garage, up to a maximum during the initial Term of the Lease of $75.00 per month
for each assigned space in the parking garage and $45.00 per month for each
unassigned space in the parking garage.  During the first five (5) years of the
Term, Tenant shall owe no monthly rent for any of the unassigned spaces on the
surface parking lot.  After the first five (5) years of the Term, the monthly
rent for surface parking spaces may be increased by Landlord during the Term to
the then-current rates charged from time to time by the operator of the surface
parking lot, up to a maximum during the initial Term of the Lease of $15.00 per
month for each unassigned space in the surface parking lot.  Monthly rent for
all parking spaces during any renewal Term of the Lease shall be the then-
current rates charged from time to time by operator of the garage and surface
parking lot.  All monthly parking rent shall be payable in advance on the first
day of each month within the Term directly to the operator of the garage and
surface parking lot, and Tenant's right to continued use of the spaces is
conditional upon receipt of those payments in a timely manner.  Tenant's rights
to use the parking garage of the Complex or the surface parking lot shall be
non-exclusive, except that Landlord shall not grant any other party the right to
use Tenant's assigned parking spaces.  Tenant's rights hereunder to use the
parking garage of the Complex or the surface parking lot are conditioned upon
this Lease being in full force and effect and there being no Event of Default by
Tenant under this Lease.  Tenant shall not abuse its privileges with respect to
the parking garage or surface parking lot and shall use the same in accordance
with Landlord's directions.

Landlord agrees that it shall construct, in connection with the initial
construction of the Building, a parking garage and surface parking lot
sufficient to furnish to Tenant the number of spaces provided above.  If at any
time during the Term of this Lease after such initial construction, Landlord
fails or is unable to provide all or any portion of the above-described parking
spaces to Tenant, or Tenant is not permitted to utilize all or any portion of
such parking spaces, for reasons related to (i) construction of additional
buildings and/or related parking or other improvements at the Complex, or (ii)
reconstruction, refurbishing, or renovation of the Building, the parking garage
or any other improvements at the Complex for reasons unrelated to a
<PAGE>

casualty thereto or condemnation thereof (each, "Landlord Controlled
Construction"), then Landlord agrees to use reasonable and diligent efforts to
replace the parking spaces which Tenant is not able to utilize, by one of the
following methods:

A.        Landlord may reserve the necessary portion of those parking spaces
which are unaffected by such Landlord Controlled Construction for the use of
Tenant.

B.   Landlord may relocate any or all of the parking spaces initially provided
     in the surface parking lot into a parking garage or other structured
     parking at the Complex; provided, however, that if such relocation is made
     necessary by virtue of Landlord Controlled Construction, then Tenant shall
     pay monthly rent for such spaces equal to the then current rate for surface
     parking spaces due from Tenant hereunder, rather than the rate then due
     from Tenant for garage spaces, for so long as the relocation is necessary
     due to Landlord Controlled Construction.

C.   Landlord may relocate any of all of the parking spaces initially provided
     in the parking garage onto a surface parking lot; provided, however, that
     if such relocation is made necessary by virtue of Landlord Controlled
     Construction, then Tenant shall pay monthly rent for such spaces equal to
     the then current rate for surface parking spaces due from Tenant hereunder,
     rather than the rate then due from Tenant for garage spaces, for so long as
     the relocation is necessary due to Landlord Controlled Construction.

D.   Landlord may arrange for alternate parking spaces located no more than
     three (3) miles away from the Building, in which case Landlord shall
     provide at its expense a shuttle service to transport the employees
     utilizing Tenant's spaces from those alternate parking spaces to the
     Building.

E.        Landlord may arrange for alternate parking spaces by any other method
which is mutually agreeable to Landlord and Tenant at the time.

     If, in connection with such Landlord Controlled Construction, (i) Landlord
fails to provide such alternate parking spaces, so that Tenant is prevented from
utilizing more than 15% of its parking spaces for a period in excess of three
(3) months, or (ii) Landlord replaces garage parking spaces with surface parking
spaces as described in subparagraph C above and such spaces are not once again
located in a parking garage at the Complex by the date which is one (1) year
from the date such spaces were initially relocated, or (iii) Landlord replaces
any parking space with off-site parking and shuttle service as described in
subparagraph D above and such parking spaces are not once again located on the
Complex by the date which is one (1) year from the date such spaces were
initially relocated, then in any of such events, Landlord shall be in default
hereunder, and Tenant shall have the right to provide Landlord with a written
notice of such default.  If Landlord has not cured such default by the date
which is thirty (30) days from the date upon which such notice is received, then
Tenant shall have the right to terminate this Lease, by written notice to
Landlord, in addition to any other rights or remedies that Tenant may have for
the breach of any covenants or conditions as may exist otherwise under this
Lease.

If at any time during the Term of this Lease, Landlord fails or is unable to
provide all or any portion of the above-described parking spaces to Tenant, or
Tenant is not permitted to utilize all or any portion of such parking spaces,
for any reason other than (i) Landlord Controlled

                                      F-2
<PAGE>

Construction, or (ii) other circumstances under Landlord's reasonable control,
such fact shall not be a default by Landlord as to permit Tenant to terminate
this Lease, either in whole or in part, but Tenant's obligation to pay rental
for any parking space which is not provided by Landlord shall be abated for so
long as Tenant does not have the use of such parking space and this abatement
shall be in full settlement of all claims that Tenant might otherwise have
against Landlord by reason of Landlord's failure or inability to provide Tenant
with such parking space. Notwithstanding the foregoing, in the event some or all
of the parking spaces become unavailable for the reasons described in the
preceding sentence, Landlord shall use commercially reasonable efforts to find
replacement parking spaces.

Except for those terms specifically defined in this Exhibit, all initially
capitalized terms herein shall have the meanings set forth for such terms in the
Lease to which this Exhibit is attached.

<PAGE>

        Premises, which portion shall consist of from 8000 to 12,000 square feet
        of Rentable Area, as designated by Landlord (the "First Expansion

        Space will be delivered by Landlord to Tenant for the purpose of
        commencing its tenant finish work therein on a date to be designated by
        Landlord, which shall be between the date which is three (3) years from

        Floor 11 of the Building which was not included within either the
        initial Premises or the First Expansion Space (the "Second Expansion
        Space"). If the second Expansion Option is exercised, the Second
        Expansion Space will be delivered by Landlord to Tenant for the purpose
        of commencing its tenant finish work therein on a date to be designated

twelve (12) months prior thereto (each, an "Occupancy Notice")."

The first sentence of new Section 3.E (former Section 3.D) of Exhibit A is

     4.  Tenant Construction Agreement Amendments.  The Tenant Construction
Agreement, contained in Exhibit D to the Lease, is amended as follows:

The Tenant Construction Agreement is revised to indicate that the architect for
the Premises has been hired by Tenant, rather than by Landlord.  As a result,
each reference in the Tenant Construction Agreement to "Landlord's architect" or
"Landlord's space planner" shall be revised to refer to "Tenant's architect" or
"Tenant's space planner."

Paragraph 6.D of the Tenant Construction Agreement is modified to provide that
the Tenant Working Drawings will be delivered by Tenant's architect to Landlord
on or before February 15, 1999.  Each day from February 15, 1999, until the day
upon which the Tenant Working Drawings are actually delivered by Tenant's
architect to Landlord, shall constitute a day of delay by Tenant in substantial
completion of the Tenant Work pursuant to Paragraph 9 of the Tenant Construction
Agreement.

The first sentence of Paragraph 9 of the Tenant Construction Agreement is
modified to read as follows:  "Subject to the provisions of Section 5.C of the
Lease and the other provisions of this Tenant Construction Agreement, Landlord
shall (i) complete the Base Building Shell or such portion thereof as is
necessary for the contractor for the Tenant Work to commence its work in the
Premises by April 1, 1999, if the Tenant Work is to be performed by GE Johnson
Construction Co., or by May 1, 1999, if the Tenant Work is to be performed by a
contractor other than GE Johnson Construction Co., and (ii) substantially
complete the Tenant Work in the Premises and tender the Premises to Tenant on or
before August 1, 1999."  Any days beyond the applicable date set forth in
subsection (i) of the preceding sentence until the contractor for the Tenant
Work is able to commence the Tenant Work in the Premises will be considered to
be a day of delay by Landlord in substantial completion of the Tenant Work
pursuant to Paragraph 9 of the Tenant Construction Agreement.  It is understood
and agreed that if the Tenant Work is to be performed by a contractor other than
GE Johnson Construction Co., the applicable date shall be the date upon which
such contractor is given permission to commence the Tenant Work in the Premises,
even if GE Johnson Construction Co. is concurrently occupying the Premises for
the purpose of completing the Base Building Shell.

The fourth sentence of Paragraph 9 of the Tenant Construction Agreement is
amended to read as follows: "The payment of Rent will not be delayed by a delay
of substantial completion due to Tenant or its architect or agents."

     5.  Brokerage Commissions.  Landlord and Tenant hereby represent and
warrant to each other that no commission is due and payable to any broker or
other leasing agent in connection with this First Amendment as a result of its
own dealings with such broker or leasing agent.  Landlord and Tenant hereby
agree to indemnify and hold each other harmless from and against all loss,
damage, cost, and expense (including reasonable attorneys' fees) suffered by the
other party as a result of a breach of the foregoing representation and
warranty.

     6.  Full Force and Effect.  Except as amended herein, all terms and
conditions of the

                                       3

Lease shall remain in full force and effect throughout the duration of the Term.
The Lease, as amended herein, constitutes the entire agreement between the

shall be binding unless evidenced by an agreement in writing signed by Landlord
and Tenant.
