                         ONLINE SYSTEM SERVICES, INC.


     This is a public offering of a maximum of 1,148,395 shares of common stock
of Online System Services, Inc. The selling shareholders are offering all of the
shares to be sold. We will not receive any of the proceeds from the offer and
sale of the shares, however, 240,420 of the shares offered by the selling
shareholders are issuable upon the exercise of issued and outstanding
transferable options and warrants of OSS at various exercise prices. If all of
these options and warrants are exercised in full, we will receive proceeds of
$2,217,692.


     The Nasdaq SmallCap Market lists our common stock under the symbol WEBB.


     Investing in our common stock involves risks.  You should not purchase our
common stock unless you can afford to lose your entire investment.  See "Risk
Factors" beginning on page 4 of this prospectus.


     Because the selling shareholders will offer and sell the shares at various
times, we have not included in this prospectus information about the price to
the public of the shares or the proceeds to the selling shareholders.


     Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of the securities or passed on the

                         ONLINE SYSTEM SERVICES, INC.

     Online System Services, Inc. (d/b/a Webb Interactive Services, Inc.)
(NASDAQ: WEBB) ("OSS" or "Webb") is developing a new generation of Internet
applications that simplify and support e-commerce transactions in local markets.
Our products provide an interactive framework of local commerce and community-
based services comprised of publishing content management, community-building
and communications.  Branded CommunityWare/XML, our products generally are
offered on a private-labeled, application service basis through high-volume
distribution partners such as yellow page publishers, newspapers, city guides
and search engines.

     To date, we have generated revenues through the sale of design and
consulting services for Web site development and network engineering services,
resale of software licenses, mark-ups on computer hardware and software sold to
customers, maintenance fees charged to customers to maintain computer hardware
and Web sites, license fees based on a percentage of revenues from our products
and services, training course fees, and monthly fees paid by customers for
Internet access which we have provided.  We commenced sales in February 1995 and
have incurred losses from operations since inception.  At June 30, 1999, we had
an accumulated deficit of $30,620,542.  The reports of our independent public
accountants for the years ended December 31, 1998 and 1997 contained a paragraph
noting substantial doubt regarding our ability to continue as a going concern.

     Based on our current projections, we have cash on hand at August 27, 1999,
which will allow us to operate through February, 1999.  Accordingly, we will
need to raise additional capital, which could involve the issuance of dilutive
equity securities and/or reduce our operating activity to conserve cash.

     Prior to the third quarter of 1997, our focus generally was on three
markets: general Web site development, maintenance and hosting; rural or small
market Internet service providers ("ISPs"); and healthcare information services
and continuing medical education.  Each of these activities involved, to varying
degrees, the building of online communities and the development of tools and
services to allow for the building of strategic and customized Web sites.  As an
outgrowth of these activities, since mid 1997, our business has evolved to the
development of online communities and more recently, the development of Internet
applications that simplify and support e-commerce transactions in local markets.

     Our application services are being developed to solve two of the largest
problems in the local online market; the failure of merchants to have their web
sites found by their target customers, and the  inability of customers to find
merchants, compare products and services, and ask questions, or conduct
transactions such as  making an appointment or requesting a bid.

     The opportunity to connect buyers and sellers in the rapidly emerging local
online market is significant.  The Kelsey Group estimates that the number of
U.S. based local businesses that are active advertisers and that have a web
presence will increase from 1.9 million in 1999 to 5.2 million in 2004.
According to Forrester Research, local online sales are projected to grow from
$680 million in 1998 to $6.1 billion in 2003.  The local only advertising
dollars spent in support of these web site activities are projected to grow from
$135 million in 1998 to $1.7 billion in 2003.

     Our application solutions are intended to provide:

     .    Local market merchants with advanced yet easy-to-use web site
          publishing tools, new ways to have their site found by their target
          customers, and services that turn web site visitors into leads,
          buyers, and repeat customers.

     .    Consumers with unique abilities to easily comparison shop and interact
          online with merchants in support of e-commerce or in-store
          transactions.

     .    Directory services and yellow page publishers who host local market
          merchant sites with enhanced services to attract a larger share of
          merchant web sites and command premium fees for site development and
          hosting.

     In addition to targeting the local directory and e-commerce markets, we
also offer online banking transaction processing and management services to
local-market focused credit unions and community banks.  Over

                                       2
<PAGE>

the next year, we intend to offer a suite of XML-enabled services to these
financial institutions to enhance customer service and support and connect their
loans and other financial services into the local e-commerce marketplace.

     We have over five years of experience in web site development and in
developing and marketing community building tools supported by a full suite of
content rich services.  Customers have included Citicorp Diners Club, Invesco
Funds Group, TCI International, Intermedia Partners and Bresnan Communications,
Inc.

     During the first six months of 1999, we acquired privately held Durand
Communications, Inc. and NetIgnite, Inc.

     We have contracted with Switchboard, Inc. as a key anchor distribution
partner in the online local directories market and with CU Cooperative Systems,
Inc. in the community banking arena.  We believe these partners provide a
critical mass of end users that will generate sustainable and recurring revenue
for Webb and a strong foundation on which to build enhanced distribution
relationships with other market leaders.  As a result of these agreements, we
expect our revenues to increase during the remainder of fiscal 1999 and beyond.

     Our strategy is to develop a competitive advantage and build a leadership
position in local e-commerce by:

     .    Delivering leading-edge technical solutions that provide first mover
          advantage and capitalize on our expertise in online community,
          communication and XML-based technologies;

     .    Securing additional distribution partnerships that drive the
          deployment of our technologies to a critical mass of end-users; and

     .    Providing innovative, value-added services to enhance buyer-seller
          interaction.

     On August 25, 1999, we issued to an investor a three-year Promissory Note
in the amount of $5,000,000 and a five-year Warrant representing the right to
acquire 136,519 shares of our common stock at an exercise price of $11.44 per
share in consideration for which the investor loaned to the Company $5,000,000.
The Note becomes convertible 120 days after issuance if it has not been redeemed
by the Company at a conversion price equal to the lesser of $11.14 or the
average of the five lowest closing bid prices for our common stock during the 15
trading days prior to the date of conversion.

     OSS was incorporated under the laws of the State of Colorado on March 22,
1994. Our executive offices are located at 1800 Glenarm Place, Suite 700,
Denver, Colorado 80202, telephone number (303) 296-9200.

                                  RISK FACTORS

     Our limited operating history could affect our business.  We were founded
in March 1994 and commenced sales in February 1995.  Accordingly, we have a
limited operating history upon which you may evaluate us.  Our business is
subject to the risks, expenses and difficulties frequently encountered by
companies with a limited operating history including:

     .    Limited ability to respond to competitive developments,

     .    Exaggerated effect of unfavorable changes in general economic and
          market conditions,

     .    Ability to attract qualified personnel, and

     .    Ability to develop and introduce new product and service offerings.

There is no assurance we will be successful in addressing these risks.  If we
are unable to successfully address these risks our business could be
significantly affected.

     We have accumulated losses since inception and we anticipate that we will
continue to accumulate losses for the foreseeable future.  We have incurred net
losses since inception totaling $30,620,542 through June 30, 1999.  In addition,
we expect to incur additional substantial operating and net losses in 1999 and
for one or more years thereafter.  We expect to incur these additional losses
because:

     .    We currently intend to increase our capital expenditures and operating
          expenses to expand the functionality and performance of our products
          and services,

     .    We recorded goodwill and other intangible assets in connection with
          the DCI and NetIgnite acquisitions which we will amortize over their
          estimated useful lives of approximately three years. We have allocated
          approximately $14.7 million to goodwill and other intangible assets in
          connection with these acquisitions.

     Net losses since inception include approximately $10.2 million of non-cash
expenses related to the issuance of preferred stock and warrants in financing
transactions and warrants issued to three customers.  The current competitive
business environment may result in our issuance of similar securities in future
financing transactions or to other companies as an inducement for them to enter
into a business relationship with us.  While these transactions represent non-
cash charges, to the extent that we enter into similar transaction in the
future, they will increase our expenses and may increase our net loss.

     If we are unable to raise additional working capital funds, we may not be
able to sustain our operations.  We believe that our present cash and cash
equivalents, working capital and commitments for additional equity investments
will be adequate to sustain our current level of operations only through
February 2000.  If we cannot raise additional funds when needed, we may be
required to curtail or scale back our operations.  These actions could have a
material adverse effect on our business, financial condition, or results of
operations.  We estimate that we will need to raise through equity, debt or
other external financing at least $10 million to sustain operations for the next
12 months.  There is no assurance that we will be able to raise additional funds
in amounts required or upon acceptable terms.  In addition, we may discover that
we have underestimated our working capital needs, and we may need to obtain
additional funds to sustain our operations.  In its report accompanying the
audited financial statements for the years ended December 31, 1998 and 1997, our
auditor, Arthur Andersen LLP, expressed substantial doubt about our ability to
continue as a going concern.

     We may never become or remain profitable.  Our ability to become profitable
depends on the ability of our  products and services to generate revenues. The
success of our revenue model will depend upon many factors including:

     .    The success of our distribution partners in marketing their products
          and services, and

     .    The extent to which consumers and businesses use our products and
          conduct e-commerce transactions and advertising utilizing our
          products.

     Because of the new and evolving nature of the Internet, we cannot predict
whether our revenue model will prove to be viable, whether demand for our
products and services will materialize at the prices we expect to be charged, or
whether current or future pricing levels will be sustainable.  Additionally, our
customer contracts may

                                       4
<PAGE>

result in significant development revenue in one quarter, which will not recur
in the next quarter for that customer. As a result, it is likely that certain
components of our revenue will be volatile, which may cause our stock price to
be volatile as well.

     Our business depends on the growth of the Internet.  Our business plan
assumes that the Internet will develop into a significant source of
communication and communication interactivity.  However, the Internet market is
new and rapidly evolving and there is no assurance that the Internet will
develop in this manner.  If the Internet does not develop in this manner, our
business, operating results and financial condition would be materially
adversely effected.  Numerous factors could prevent or inhibit the development
of the Internet in this manner, including:

     .    The failure of the Internet's infrastructure to support Internet usage
          or electronic commerce,

     .    The failure of businesses developing and promoting Internet commerce
          to adequately secure the confidential information, such as credit card
          numbers, needed to carry out Internet commerce, and

     .    Regulation of Internet activity

     Use of many of our products and services will be dependent on distribution
partners.  Because we have elected to partner with other companies for the
distribution of many of our products and services, many users of our products
and services are expected to subscribe through our distribution partners.  As a
result, our distribution partners, and not us, will substantially control the
customer relationship with these users.  If the business of the companies with
whom we partner is adversely affected in any manner our business, operating
results and financial condition could be materially adversely effected.

     We may be unable to develop desirable products.  Our products are subject
to rapid obsolescence and our future success will depend upon our ability to
develop new products and services that meet changing customer and marketplace
requirements.  There is no assurance that we will be able to successfully:

     .    Identify new product and service opportunities, or

     .    Develop and introduce new products and services to market in a timely
          manner.

     If we are unable to accomplish these items, our business, operating results
and financial condition could be materially adversely affected.

     Our products and services may not be successful.  Even if we are able to
successfully identify, develop, and introduce new products and services there is
no assurance that a market for these products and services will materialize to
the size and extent that we anticipate.  If a market does not materialize as we
anticipate, our business, operating results, and financial condition could be
materially adversely affected.  The following factors could affect the success
of our products and services:

     .    The failure of our business plan to accurately predict the rate at
          which the market for Internet products and services will grow,

     .    The failure of our business plan to accurately predict the types of
          products and services the future Internet marketplace will demand,

     .    Our limited experience in marketing our products and services,

     .    The failure of our business plan to accurately predict our future
          participation in the Internet marketplace,

     .    The failure of our business plan to accurately predict the estimated
          sales cycle, price, and acceptance of our products and services,

     .    The development by others of products and services that renders our
          products and services noncompetitive or obsolete, or

     .    Our failure to keep pace with the rapidly changing technology,
          evolving industry standards, and frequent new product and service
          introductions that characterize the Internet marketplace.

     The intense competition that is prevalent in the Internet market could have
a material adverse effect on our business.  Our current and prospective
competitors include many companies whose financial, technical, marketing and
other resources are substantially greater than ours.  There is no assurance that
we will have the financial resources, technical expertise, or marketing, sales
and support capabilities to compete successfully.  The

                                       5
<PAGE>

presence of these competitors in the Internet marketplace could have a material
adverse effect on our business, operating results, or financial condition by
causing us to:

     .    Reduce the average selling price of our products and services, or

     .    Increase our spending on marketing, sales, and product development.

     There is no assurance that we would be able to offset the effects of any
such price reductions or increases in spending through an increase in the number
of our customers, higher sales from premium services, cost reductions or
otherwise.  Further, our financial condition may put us at a competitive
disadvantage relative to our competitors.  If we fail to, or cannot, meet
competitive challenges, our business, operating results and financial condition
could be materially adversely affected.

     A limited number of our customers generate a significant portion of our
revenues.  We had four customers representing 77% of revenues for the June 30,
1999 three-month period and four customers representing 82% of net revenues for
the similar 1998 period. We had four customers representing 83% of revenues for
the June 30, 1999 six-month period and three customers representing 74% of
revenues for the similar 1998 period. There is no assurance that we will be able
to attract or retain major customers. The loss of, or reduction in demand for
products or related services from major customers could have a material adverse
effect on our business, operating results, cashflows, and financial condition.

     The sales cycle for our products and services is lengthy and unpredictable.
While our sales cycle varies from customer to customer, it typically has ranged
from one to six months for projects.  Our pursuit of sales leads typically
involves an analysis of our prospective customer's needs, preparation of a
written proposal, one or more presentations and contract negotiations.  We often
provide significant education to prospective customers regarding the use and
benefits of our Internet technologies and products.  Our sales cycle may also be
affected by a prospective customer's budgetary constraints and internal
acceptance reviews, over which we have little or no control.  In order to
quickly respond to, or anticipate, customer requirements, we may begin
development work prior to having a signed contract, which exposes us to the risk
that the development work will not be recovered from revenue from that customer.

     We may be unable to adjust our spending to account for potential
fluctuations in our quarterly results.  As a result of our limited operating
history, we do not have historical financial data for a sufficient number of
periods on which to base planned operating expenses.  Therefore, our expense
levels are based in part on our expectations as to future sales and to a large
extent are fixed.  We typically operate with little backlog and the sales cycles
for our products and services may vary significantly.  As a result, our
quarterly sales and operating results generally depend on the volume and timing
of and the ability to close customer contracts within the quarter, which are
difficult to forecast.  We may be unable to adjust spending in a timely manner
to compensate for any unexpected sales shortfalls.  If we were unable to so
adjust, any significant shortfall of demand for our products and services in
relation to our expectations would have an immediate adverse effect on our
business, operating results and financial condition.  Further, we currently
intend to increase our capital expenditures and operating expenses to fund
product development and increase sales and marketing efforts.  To the extent
that such expenses precede or are not subsequently followed by increased sales,
our business, operating results and financial condition will be materially
adversely affected.

     We may be unable to retain our key executives and research and development
personnel. Our future success also depends in part on our ability to identify,
hire and retain additional personnel, including key product development, sales,
marketing, financial and executive personnel. Competition for such personnel is
intense and there is no assurance that we can identify or hire additional
qualified personnel.

     Executives and research and development personnel who leave us may compete
against us in the future.  We generally enter into written nondisclosure and
nonsolicitation agreements with our officers and employees

                                       6
<PAGE>

which restrict the use and disclosure of proprietary information and the
solicitation of customers for the purpose of selling competing products or
services. However, we generally do not require our employees to enter into non-
competition agreements. Thus, if any of these officers or key employees left,
they could compete with us, so long as they did not solicit our customers. Any
such competition could have a material adverse effect on our business.

     We may be unable to manage our expected growth.  If we are able to
implement our growth strategy, we will experience significant growth in the
number of our employees, the scope of our operating and financial systems, and
the geographic area of our operations.  There is no assurance that we will be
able to implement in whole or in part our growth strategy or that our management
or other resources will be able to successfully manage any future growth in our
business.  Any failure to do so could have a material adverse effect on our
operating results and financial condition.

     We may be unable to protect our intellectual property rights.  Intellectual
property rights are important to our success and our competitive position.
There is no assurance that the steps we take to protect our intellectual
property rights will be adequate to prevent the imitation or unauthorized use of
our intellectual property rights.  Policing unauthorized use of proprietary
systems and products is difficult and, while we are unable to determine the
extent to which piracy of our software exists, we expect software piracy to be a
persistent problem.  In addition, the laws of some foreign countries do not
protect software to the same extent as do the laws of the United States.  Even
if the steps we take to protect our proprietary rights prove to be adequate, our
competitors may develop products or technologies that are both non-infringing
and substantially equivalent or superior to our products or technologies.

     Computer viruses and similar disruptive problems could have a material
adverse effect on our business.  Our software and equipment may be vulnerable to
computer viruses or similar disruptive problems caused by our customers or other
Internet users.  Our business, financial condition or operating results could be
materially adversely effected by:

     .    Losses caused by the presence of a computer virus that causes us or
          third parties with whom we do business to interrupt, delay or cease
          service to our customers,

     .    Losses caused by the misappropriation of secured or confidential
          information by a third party who, in spite of our security measures,
          obtains illegal access to this information,

     .    Costs associated with efforts to protect against and remedy security
          breaches, or

     .    Lost potential revenue caused by the refusal of consumers to use our
          products and services due to concerns about the security of
          transactions and commerce that they conduct on the Internet.

     Future government regulation could materially adversely effect our
business.  There are currently few laws or regulations directly applicable to
access to, communications on, or commerce on the Internet.  Therefore, we are
not currently subject to direct regulation of our business operations by any
government agency, other than regulations applicable to businesses generally.
Due to the increasing popularity and use of the Internet, however, federal,
state, local, and foreign governmental organizations are currently considering a
number of legislative and regulatory proposals related to the Internet.  The
adoption of any of these laws or regulations may decrease the growth in the use
of the Internet, which could, in turn:

     .    Decrease the demand for our products and services,

     .    Increase our cost of doing business, or

     .    Otherwise have a material adverse effect on our business, results of
          operations and financial condition.

     Moreover, the applicability to the Internet of existing laws governing
issues such as property ownership, copyright, trademark, trade secret,
obscenity, libel and personal privacy is uncertain and developing.  Our
business, results of operations and financial condition could be materially
adversely effected by the application or interpretation of these existing laws
to the Internet.

     Our systems may not be year 2000 compliant.  We have reviewed our internal
software and hardware systems.  Based on this review, we believe that our
internal software and hardware systems will function properly with respect to
dates in the year 2000 and thereafter.  We expect to incur no significant costs
in the future for Year 2000 problems.  Nonetheless, there is no assurance in
this regard until our internal software and hardware systems are operational in
the year 2000.

                                       7
<PAGE>

     The failure to correct material Year 2000 problems by our suppliers and
vendors could result in an interruption in, or a failure of, certain of our
normal business activities or operations.  Due to the general uncertainty
inherent in the Year 2000 problem, resulting from the uncertainty of the Year
2000 readiness of third-party suppliers and vendors and of our customers, we are
unable to determine at this time that the consequences of Year 2000 failures
will not have a material impact on our results of operations, liquidity or
financial condition.

     Our articles of incorporation and bylaws may discourage lawsuits and other
claims against our directors.  Our articles of incorporation provide, as
permitted by Colorado law, that our directors shall have no personal liability
for certain breaches of their fiduciary duties to us.  In addition, our bylaws
provide for mandatory indemnification of directors and officers to the fullest
extent permitted by Colorado law.  These provisions may reduce the likelihood of
derivative litigation against directors and may discourage shareholders from
bringing a lawsuit against directors for a breach of their duty.

     The price of our common stock has been highly volatile due to factors that
will continue to effect the price of our stock.  Our common stock traded as high
as $19.38 per share and as low as $9.13 between January 1, 1999 and August 6,
1999.  Historically, the over-the-counter markets for securities such as our
common stock have experienced extreme price and volume fluctuations.  Some of
the factors leading to this volatility include:

     .    Price and volume fluctuations in the stock market at large that do not
          relate to our operating performance,

     .    Fluctuations in our quarterly revenue and operating results,

     .    Announcements of product releases by us or our competitors,

     .    Announcements of acquisitions and/or partnerships by us or our
          competitors, and

     .    Increases in outstanding shares of common stock upon exercise or
          conversion of derivative securities.

     These factors may continue to affect the price of our common stock in the
future.

     The trading volume of our common stock may diminish significantly if our
common stock is prohibited from being traded on the Nasdaq SmallCap Market.
Although our shares are currently traded on The Nasdaq SmallCap Market, there is
no assurance that we will remain eligible to be included on Nasdaq.  If our
common stock was no longer eligible for quotation on Nasdaq, it could become
subject to rules adopted by the Securities and Exchange Commission regulating
broker-dealer practices in connection with transactions in "penny stocks."  If
our common stock became subject to the penny stock rules, many brokers may be
unwilling to engage in transactions in our common stock because of the added
regulation, thereby making it more difficult for purchasers of our common stock
to dispose of their shares.

     We have issued numerous options, warrants, and convertible securities to
acquire our common stock that could have a dilutive effect on our shareholders.
We have issued numerous options, warrants, and convertible securities to acquire
our common stock.  During the terms of these outstanding options, warrants, and
convertible securities, the holders of these securities will have the
opportunity to profit from an increase in the market price of our common stock
with resulting dilution to the holders of shares who purchased shares for a
price higher than the respective exercise or conversion price.  The existence of
such stock options, warrants and convertible securities may adversely affect the
terms on which we can obtain additional financing, and you should expect the
holders of such options or warrants to exercise or convert those securities at a
time when we, in all likelihood, would be able to obtain additional capital by
offering securities on terms more favorable to us than those provided by the
exercise or conversion of such options or warrants.

     As of August 6, 1999, we have issued the following warrants and options to
acquire shares of our common stock:

     .    Options and warrants to purchase 1,919,228 shares of common stock upon
          exercise of such options and warrants, exercisable at prices ranging
          from $0.50 to $18.25 per share, with a weighted average exercise price
          of approximately $9.08 per share.

     .    Options issued to EBI Securities Corporation, the representative of
          the underwriters involved in our initial public offering (the
          "Representative's Option"), to purchase 106,700 shares of common stock
          upon exercise of the Representative's Option at a purchase price of
          $8.10 per share.

                                       8
<PAGE>

     .    Warrants issued in connection with the issuance of the 10% Preferred
          Stock to purchase 53,500 shares of common stock upon exercise of such
          warrants, exercisable at $15.00 per share.

     .    Warrants issued in connection with the issuance of the 5% Preferred
          Stock to purchase 100,000 shares of common stock upon exercise of such
          warrants, exercisable at $16.33 per share.

     .    Warrants issued to customers to purchase 81,829 shares of common stock
          upon exercise of such warrants, exercisable at $8.77 to $9.94

     .    Warrants issued to purchase 223,700 shares of common stock at prices
          ranging from $4.30 to $20.33 assumed in connection with the
          acquisition of DCI.

     In addition to these warrants and options, we have reserved an
indeterminate number of shares of common stock for issuance upon conversion of
outstanding shares of our 10% and Series C Preferred Stock.  Based on the market
value for the common stock as of August 6, 1999, the then outstanding 10%
Preferred Stock and Series C Preferred Stock were convertible into approximately
113,108 shares and 78,853 shares, respectfully, of common stock.  The number of
shares of common stock issuable upon conversion of the 10% Preferred Stock and
the Series C Preferred Stock could increase significantly if the market value
for our common stock decreases in the future.  Further, there could be issuances
of additional similar securities in connection with our need to raise additional
working capital.

     Future sales of our common stock in the public market could adversely
affect the price of our common stock.  Sales of substantial amounts of common
stock in the public market that is not currently freely tradable, or even the
potential for such sales, could have an adverse affect on the market price for
shares of our common stock and could impair the ability of purchasers of our
common stock to recoup their investment or make a profit.  As of August 6, 1999,
these shares consist of:

     .    Approximately 630,000 shares owned by our officers, directors and
          holders of 10% of our outstanding common stock ("Affiliate Shares"),
          and

     .    The shares being offered pursuant to this Prospectus.

     Unless the Affiliate Shares are further registered under the securities
laws, they may not be resold except in compliance with Rule 144 promulgated by
the SEC, or some other exemption from registration.  Rule 144 does not prohibit
the sale of these shares but does place conditions on their resale which must be
complied with before they can be resold. The shares of the common stock  issued
to the shareholders of DCI in connection with the DCI acquisition are expected
to be registered pursuant to the Securities Act of 1933 by September 30, 1999.

     Future sales of our common stock in the public market could limit our
ability to raise capital.  Sales of substantial amounts of common stock in the
public market pursuant to Rule 144, upon exercise or conversion of derivative
securities or otherwise, or even the potential for such sales, could affect our
ability to raise capital through the sale of equity securities.

     Provisions in our articles of incorporation allow us to issue shares of
stock that could make a third party acquisition of us difficult.  Our Articles
of Incorporation authorize our Board of Directors to issue up to 20,000,000
shares of common stock and 5,000,000 shares of preferred stock in one or more
series, the terms of which may be determined at the time of issuance by the
Board of Directors, without further action by our shareholders.  Preferred stock
authorized by the Board of Directors may include voting rights, preferences as
to dividends and liquidation, conversion and redemptive rights and sinking fund
provisions.  If the Board of Directors authorizes the issuance of preferred
stock in the future, this authorization could affect the rights of the holders
of common stock, thereby reducing the value of the common stock, and could make
it more difficult for a third party to acquire us, even if a majority of the
holders of our common stock approved of an acquisition.

     Our issuance of warrants to a customer will require us to record a non-cash
expense which will, in turn, increase our net loss available to shareholders. We
will record a non-cash expense in the amount of approximately $900,000 during
the quarter ending September 30, 1999 as a result of our issuance of a three-
year warrant to acquire 150,000 shares to a customer. In addition, the agreement
with the customer contemplates the issuance of a second warrant, subject to
certain conditions, to purchase 150,000 shares of common stock which, if issued,
could result in similar charges in the future.

                                       9

     We do not anticipate paying dividends on our common stock for the
foreseeable future.  We have never paid dividends on our common stock and do not
intend to pay any dividends on our common stock in the foreseeable future.  Any
decision by us to pay dividends on our common stock will depend upon our
profitability at the time, cash available therefor, and other factors.  We
anticipate that we will devote profits, if any, to our future operations.



               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     Some of the statements made in this prospectus and the documents
incorporated by reference in this prospectus under the captions "Online System
Services, Inc.," "Risk Factors,"  "Recent Developments" and elsewhere in this
prospectus constitute forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995.  These statements are subject
to the safe harbor provisions of the reform act.  Forward-looking statements may
be identified by the use of the terminology such as may, will, expect,
anticipate, intend, believe, estimate, should, or continue or the negatives of
these terms or other variations on these words or comparable terminology.  To
the extent that this prospectus contains forward-looking statements regarding
the financial condition, operating results, business prospects or any other
aspect of OSS, you should be aware that our actual financial condition,
operating results and business performance may differ materially from that
projected or estimated by OSS in the forward-looking statements. We have
attempted to identify, in context, some of the factors that we currently believe
may cause actual future experience and results to differ from their current
expectations. These differences may be caused by a variety of factors, including
but not limited to adverse economic conditions, intense competition, including
entry of new competitors, ability to obtain sufficient financing to support our
operations, progress in research and development activities, variations in costs
that are beyond our control, changes in capital expenditure budgets for cable
companies, adverse federal, state and local government regulation, inadequate
capital, unexpected costs, lower sales and net income, or higher net losses than
forecasted, price increases for equipment, inability to raise prices, failure to
obtain new customers, the possible fluctuation and volatility of our operating
results and financial condition, inability to carry out marketing and sales
plans, loss of key executives, and other specific risks that may be alluded to
in this prospectus.


                                USE OF PROCEEDS

     We will not receive any of the proceeds from the offer and sale of the
shares, however, 240,420 of the shares offered by the selling shareholders are
issuable upon the exercise of issued and outstanding transferable options of OSS
at various exercise prices, pursuant to the terms of the Merger.  If all of
these options are exercised in full, we will receive proceeds of $2,217,692.



                              SELLING SHAREHOLDERS

     The selling shareholders have indicated that the shares offered by this
prospectus may be sold from time to time by them or by their pledgees, donees,
transferees or other successors in interest.  The following table shows as of
August 1, 1999:

     .    The name of each of the selling shareholders,

     .    The number of shares of our common stock beneficially owned by each of
          the selling shareholders, and

     .    The number and percentage of securities offered by this prospectus
          that may be sold from time to time by each of the selling
          shareholders.

     In addition, under the registration statement of which this prospectus is a
part we have registered an additional number of shares of our common stock that
we may be required to issue to the selling shareholders as a result of any stock
split, stock dividend or similar transaction involving our common stock.  In the
following table, we have calculated percentage ownership by assuming that all
shares of common stock which the selling

                                       10
<PAGE>

shareholder has the right to acquire within 60 days from the date of this
prospectus upon the exercise of options, warrants, or convertible
securities are outstanding for the purpose of calculating the percentage of
common stock owned by the selling shareholder.

     There is no assurance that the selling shareholders will sell the shares
offered by this prospectus.

                             PLAN OF DISTRIBUTION

     The sale of the shares offered by this prospectus may be made in the Nasdaq
SmallCap Market or other over-the-counter markets at prices and at terms then
prevailing or at prices related to the then current market price or in
negotiated transactions. These shares may be sold by one or more of the
following:

     .    A block trade in which the broker or dealer will attempt to sell
          shares as agent but may position and resell a portion of the block as
          principal to facilitate the transaction.

     .    Purchases by a broker or dealer as principal and resale by a broker or
          dealer for its account using this prospectus.

     .    Ordinary brokerage transactions and transactions in which the broker
          solicits purchasers.

     .    In privately negotiated transactions not involving a broker or dealer.

     In effecting sales, brokers or dealers engaged to sell the shares may
arrange for other brokers or dealers to participate. Brokers or dealers engaged
to sell the shares will receive compensation in the form of commissions or
discounts in amounts to be negotiated immediately prior to each sale. These
brokers or dealers and any other participating brokers or dealers may be deemed
to be underwriters within the meaning of the Securities Act of 1933 in
connection with these sales. OSS will receive no proceeds from any resales of
the shares offered by this prospectus, and we anticipate that the brokers or
dealers, if any, participating in the sales of the shares will receive the usual
and customary selling commissions.

     To comply with the securities laws of some states, if applicable, the
shares will be sold in these states only through brokers or dealers. In
addition, in some states, the shares may not be sold in those states unless they
have been registered or qualified for sale in these states or an exemption from
registration or qualification is available and is complied with.


                           DESCRIPTION OF SECURITIES

General

     Our articles of incorporation authorize our board of directors to issue
25,000,000 shares of capital stock, including 20,000,000 shares of common stock
and 5,000,000 shares of preferred stock, with rights, preferences and privileges
as are determined by our board of directors.

Common Stock

     As of August 6, 1999, we had 7,487,532 shares of common stock outstanding.
All outstanding shares of our common stock are fully paid and nonassessable and
the shares of our common stock offered by this prospectus will be, upon
issuance, fully paid and nonassessable.  The following is a summary of the
material rights and privileges of our common stock.

     Voting.  Holders of our common stock are entitled to cast one vote for each
share held at all shareholder meetings for all purposes, including the election
of directors. The holders of more than 50% of the voting power of our common
stock issued and outstanding and entitled to vote and present in person or by
proxy, together with any preferred stock issued and outstanding and entitled to
vote and present in person or by proxy, constitute a quorum at all meetings of
our shareholders. The vote of the holders of a majority of our common stock
present and entitled to vote at a meeting, together with any preferred stock
present and entitled to vote at a meeting, will decide any question brought
before the meeting, except when Colorado law, our articles of incorporation, or
our bylaws require a greater vote and except when Colorado law requires a vote
of any preferred stock issued and outstanding, voting as a separate class, to
approve a matter brought before the meeting. Holders of our common stock do not
have cumulative voting for the election of directors.

                                       13

     Dividends.  Holders of our common stock are entitled to dividends when, as
and if declared by the board of directors out of funds available for
distribution. The payment of any dividends may be limited or prohibited by loan
agreement provisions or priority dividends for preferred stock that may be
outstanding.

     Preemptive Rights.  The holders of our common stock have no preemptive
rights to subscribe for any additional shares of any class of our capital stock
or for any issue of bonds, notes or other securities convertible into any class
of our capital stock.

     Liquidation.  If we liquidate or dissolve, the holders of each outstanding
share of our common stock will be entitled to share equally in our assets
legally available for distribution to our shareholders after payment of all
liabilities and after distributions to holders of preferred stock legally
entitled to be paid distributions prior to the payment of distributions to
holders of our common stock.

     The financial statements incorporated by reference in this prospectus and
elsewhere in the registration statement have been audited by Arthur Andersen
LLP, independent public accountants, as indicated in their reports with respect
thereto, and are included herein in reliance upon the authority of said Firm as
experts in giving said reports. Reference is made to said report, which includes
an explanatory paragraph with respect to the uncertainty regarding the Company's
ability to continue as a going concern as discussed in Note 1 to the financial

                                INDEMNIFICATION

     Our articles of incorporation provide that we shall indemnify, to the full
extent permitted by Colorado law, any of our directors, officers, employees or
agents who are made, or threatened to be made, a party to a proceeding by reason
of the fact that he or she is or was one of our directors, officers, employees
or agents against judgments, penalties, fines, settlements and reasonable
expenses incurred by the person in connection with the proceeding if specified
standards are met. Although indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to our directors, officers and
controlling persons under these provisions, we have been advised that, in the
opinion of the SEC, indemnification for liabilities arising under the Securities
Act of 1933 is against public policy as expressed in the Securities Act and is,
therefore, unenforceable.

     Our articles of incorporation also limit the liability of our directors to
the fullest extent permitted by the Colorado law. Specifically, our articles of
incorporation provide that our directors will not be personally liable for
monetary damages for breach of fiduciary duty as directors, except for:

     .    Any breach of the duty of loyalty to OSS or its shareholders,

     .    Acts or omissions not in good faith or that involved intentional
          misconduct or a knowing violation of law,

     .    Dividends or other distributions of corporate assets that are in
          contravention of specified statutory or contractual restrictions,

     .    Violations of specified laws, or

     .    Any transaction from which the director derives an improper personal
          benefit.

Item 15.  Indemnification of Officers and Directors

     OSS's articles of incorporation provide that OSS shall indemnify, to the
full extent permitted by Colorado law, any director, officer, employee or agent
of OSS made or threatened to be made a party to a proceeding, by reason of the
fact that such person is or was a director, officer, employee or agent of OSS
against judgments, penalties, fines, settlements and reasonable expenses
incurred by the person in connection with the proceeding if certain standards
are met.  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the "Act") may be permitted to directors, officers and
controlling persons of OSS pursuant to the foregoing provisions, or otherwise,
OSS 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.

     OSS's articles of incorporation limit the liability of its directors to the
fullest extent permitted by Colorado law.  Specifically, the articles of
incorporation provide that directors of OSS will not be personally liable for
monetary damages for breach of fiduciary duty as directors, except for (i) any
breach of the duty of loyalty to OSS or its shareholders, (ii) acts or omissions
not in good faith or that involved intentional misconduct or a knowing violation
of law, (iii) dividends or other distributions of corporate assets that are in
contravention of certain statutory or contractual restrictions, (iv) violations
of certain laws, or (v) any transaction from which the director derives an
improper personal benefit.  Liability under federal securities law is not
limited by the Articles.

Item 17.  Undertakings

     A.   The undersigned registrant hereby undertakes:

          (1) to file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement to:

              (a)  include any prospectus required by Section 10(a)(3) of the
                   Securities Act of 1933,

              (b)  to reflect in the prospectus any facts or events arising
                   after the effective date of the registration statement (or
                   the most recent post-effective amendment thereof) which,
                   individually or together, represent a fundamental change in
                   the information in the registration statement, and

              (c)  to include any additional or changed material information on
                   the plan of distribution;

          (2) to treat, for determining liability under the Securities Act of
     1933, each such post-effective amendment as 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; and

          (3) to remove from registration by means of a post-effective amendment
     any of the securities being registered that remain unsold at the
     termination of the offering.

     B.   Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers, and controlling
persons of the registrant as discussed above, 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.

     RE:  Form S-3 Registration Statement

Ladies/Gentlemen:

     This opinion is furnished in connection with the registration, pursuant to
the Securities Act of 1933, as amended, of a maximum of 1,148,395 shares of
common stock, no par value (the "Shares"), of Online System Services, Inc. (the
"Company" or "OSS") issued in connection with the merger of Durand Acquisition
Corporation, a wholly-owned subsidiary of the Company, and Durand
Communications, Inc., for services rendered and issuable upon the exercise of
outstanding transferable options and warrants of OSS which may be sold from time
to time by various selling shareholders for their own account.

     We have acted as counsel to the Company in connection with the preparation
of the Form S-3 Registration Statement (the "Registration Statement").  We have
examined the Articles of Incorporation, as amended, the Bylaws of the Company,
such records of proceedings of the Company as we deemed material and such other
certificates, records and documents as we considered necessary for the purposes
of this opinion.

     Based on the foregoing, we are of the opinion that the Shares issued in
connection with the merger and for services rendered are, and the shares to be
issued upon exercise of options or warrants or conversion of convertible
securities will be, when issued in accordance with the terms of such securities,
legally issued, fully paid and non-assessable securities of the Company. We
understand that this opinion is to be issued in connection with the Registration
Statement. We consent to a filing of a copy of this opinion with the
Registration Statement.

                                          Very truly yours,

                                          GRAY, PLANT, MOOTY,
                                           MOOTY & BENNETT, P.A.

                   DEVELOPMENT, ACCESS AND LICENSE AGREEMENT

This Development, Access and License Agreement ("Agreement") entered into as of

to SB the Integration Enabling Version of the XML Site Generation Platform by
June 30, 1999, and complete and deliver to SB the Production Development Version
of the XML Site Generation Platform by July 31, 1999, both as part of Phase 1.
(Each version referenced in the previous sentence shall be as defined in the
Phase 1 Specification.)  In the event that SB requests any reasonable changes to
the Phase 1 Specifications, the completion dates specified above shall be
extended a reasonable amount of time to allow for implementation of such
changes.

3.2  Phase 2.  Commencing on the acceptance of Phase 1 in accordance with
     -------
Section 3.4, WEBB will develop an expanded version of the XML Site Generation
Platform ("Phase 2"), integrating the requirements and specifications jointly
defined by SB and WEBB ("Phase 2 Specifications") which shall incorporate the
following types of features:

     (a)  Vertical templates for 10 categories of businesses, including clip art
          and design formats and data intake interfaces for each;

Unless otherwise agreed by SB and without limitation, WEBB will be responsible
for providing all design, art, content tagging and other functional elements
that make each Vertical Template.  WEBB shall complete and deliver to SB the
Phase 2 deliverables by the later of September 30, 1999 or within sixty (60)
days after the due date for delivery of the Integration Enabling Version of the
XML Site Generation Platform in Phase 1, provided that the Phase 2
Specifications are agreed to by the Parties by July 15, 1999. The parties shall
use good faith efforts to agree to the Phase 2 Specifications by July 15, 1999.
If they fail to do so, the delivery date for Phase 2 deliverables shall be moved
back by the number of days equivalent to the number of days between July 15,
1999 and the completion of the Phase 2 Specifications.  In the event that SB
requests any reasonable changes to the Phase 2 Specifications, the completion
dates specified above shall be extended a reasonable amount of time to allow for

          Template Sites.

     (d)  Extension and modification of XML site generation platform required to
          deploy and administer multiple outlet dealer networks from common
          templates

Subject, to the foregoing, WEBB shall complete the Phase 3 deliverables on or
before December 31, 1999 provided that the Phase 3 Specifications are agreed to
by the Parties by September 15, 1999. The parties shall use good faith efforts
to agree to the Phase 3 Specifications by September 15, 1999.  If they fail to
do so, the delivery date for Phase 3 deliverables shall be moved back by the
number of days equivalent to the number of days between September 15, 1999 and
the completion of the Phase 3 Specifications.  In the event that SB requests any
reasonable changes to the Phase 3 Specifications, the completion dates specified
above shall be extended a reasonable amount of time to allow for implementation
of such changes.

3.4  Acceptance.  WEBB shall use good faith efforts to ensure that the
     ----------
developments for each Phase conform to the applicable Specification.  Upon
completion of each of Phase 1, 2 and, if applicable, 3, WEBB shall submit such
developments to SB for acceptance by the dates set forth above.  SB shall have
ten (10) business days to test such deliverables to determine whether they
conform in all material respects to the applicable Specifications.  In the event
that SB reasonably determines that the deliverables associated with any Phase do
not conform in all material respects to the applicable Specification, SB shall
so notify WEBB in writing, indicating the nature of the non-conformities. WEBB
shall then have ten (10) business days to correct any non-conformities so that
the deliverables for such Phase conform in all material respects to the
applicable Specifications.  Upon delivery of such corrected Phase developments,
SB shall again have ten (10) business days to test such deliverables to
determine whether they conform in all material respects to applicable
Specifications.  If SB reasonably determines that they do not, SB may, at its
election, terminate this Agreement upon ten (10) days' prior written notice to
WEBB, provided that WEBB does not cure such non-conformities during such ten
(10)-day period.  In the event that SB does not accept any Phase deliverables in
accordance with this Section, the then-current term of exclusivity, if any,
shall be extended for a period of time equal to the time between the initial
non-conforming delivery and acceptance by SB.  Further, SB shall not be
obligated to make the minimum payment due on September 30, 1999 pursuant to
Section 7.3 unless and until it has accepted the Phase 1 development.  If SB
does not advise WEBB in writing that the deliverables do not conform in all
material respects to the applicable Specifications within the applicable ten
(10)-day period, the deliverables shall be deemed to be in conformance with the
applicable Specifications.

3.5  Requested Modifications. WEBB hereby agrees to make reasonable changes
     -----------------------
requested by SB during the Term of this Agreement to or in connection with the
Programmatic Interfaces or XML Definitions for no additional charge for minor

4.9  Interruption of Service In the event of an interruption of service during
     -----------------------
normal business hours caused by WEBB or the XML Site Generation Platform which
renders the XML Site Generation Platform, including without limitation, data
entry interfaces created by WEBB, unavailable to SB, SB Contractors or SB
Customers for reasons other than network or technology components out of the
control of WEBB (subject to WEBB's obligation to comply with the provisions of
Section 4.12), WEBB shall, in addition to its other obligations under this
Agreement, provide services required to restore continuous operation as follows:

     a)   WEBB shall notify SB within 2 hours of discovering such failure, or
          respond to SB within 1 hour after notification by SB.

     b)   WEBB shall have 4 hours after discovery or notification of
          interruption of service to inform SB of the status of its progress in
          identifying the problem and its plan for resolution. Switchboard will
          provide WEBB with reasonable assistance required to isolate the origin
          of such interruption. Until the problem is resolved, WEBB will give SB
          regular status updates, no less often than once a day, on
          identification of cause, remedies and estimated times to recover.

     c)   WEBB shall cache all information and data transmitted to the XML
          Software up to the point of service interruption relating to web sites
          which were not completed due to such interruption. WEBB shall use good
          faith efforts to develop in connection with Phase 2 an application to
          be used during the period of service interruption that would allow the
          XML Site Generation Platform to receive and store the same type of
          information and data from SB, SB Contractors, and SB Customers as the
          XML Site Generation Platform was able to receive before the service
          interruption. During the period of service interruption, until the
          installation of an application referred to in this Section, SB and SB
          Contractors shall cache all information and data normally transmitted
          to the XML Site Generation Platform in a format mutually acceptable to
          SB and WEBB. Upon the resolution of the problem causing such service
          interruption, the parties shall agree on a method for transmitting to
          WEBB any information or data which has been cached by SB or SB
          Contractors and WEBB shall ensure that the XML Site Generation
          Platform shall process all information and data which has been cached
          in the order received by WEBB, unless otherwise mutually agreed by SB
          and WEBB.

     d)   To restore service, WEBB shall have a right to temporarily revert to
          the most recent stable version of the XML Software without SB's
          consent, provided that such prior version is within the same Phase
          implementation. (For example, if SB has accepted the Phase 2 version
          of the XML Software prior to the interruption of service, WEBB may
          revert only to a prior version of Phase 2, if any. WEBB may not revert
          to a Phase 1 version without SB's prior written consent.) WEBB shall
          revert back to the most current version of the XML Software promptly
          upon resolution of the problem which caused the interruption.

                                       6
<PAGE>

     e)   WEBB shall use commercially reasonable efforts to remedy the problem
          with the then-current version of the XML Software as quickly as
          possible.

4.10 Service Interruption Fee.  If there is a service interruption after
     ------------------------
September 1, 1999 or, if later, after SB has completed its required integration
work, and WEBB has not created an application to allow for the receipt and
storage of information and data from SB, SB Contractors, or SB Customers as
described in Section 4.9(c), SB and/or SB Contractors who are denied access to
the XML Site Generation Platform may, upon resumption of service and access to
the XML Site Generation Platform, re-enter such cached data and information into
data entry interfaces provided by the XML Site Generation Platform. SB shall
charge WEBB a fee of $16 for each web site for which SB or SB Contractors re-
enter such data and information as provided above, provided that the customer
for whom such data was required to be re-entered is or becomes a regular paying
customer of SB. WEBB agrees to pay SB the applicable charges within 30 days
after the end of the month in which SB's or SB Contractor's data re-entry
activities are completed.

4.11 Chronic Interruptions of Service.  If after September 1, 1999 or, if later,
     --------------------------------
after SB has completed its required integration work, the XML Site Generation
Platform is unavailable to SB, SB's Contractors and/or SB Customers for a
continuous period of seven (7) days, or for a cumulative period of 120 hours
over a period of thirty (30) days, then SB may at its election terminate this
Agreement upon written notice to WEBB.

4.12 Maintenance of Performance Standards.  During the period when WEBB is
     ------------------------------------
hosting the XML Site Generation Platform, WEBB shall (a) use commercially
reasonable efforts to keep such XML Site Generation Platform continually
available to SB, SB Contractors and SB Customers, on a 24x7 basis; and (b)
maintain at least the infrastructure and operational standards set forth in
Exhibit B.

               Section 5:  Restrictive Covenants of the Parties
               ------------------------------------------------

5.1  Exclusivity.  Throughout the Exclusivity Period and to the extent lawful
     -----------
under applicable laws and regulations, WEBB covenants and agrees that except as
provided below it will not directly or indirectly license the XML Site
Generation Platform or provide access to its XML Site Generation Platform to (i)
yellow page or business directory publishers, media companies, financial service
organizations, (for the purposes of this Section, "Competitive Entities") or
(ii) other organizations for the purpose of providing web sites to small or
medium-sized businesses with primary markets in the United States. (For the
purposes of this Agreement, a "small or medium-sized business" shall mean
businesses which employ fewer than 200 full or part-time employees.) This
Agreement and this Section 5.1 will not restrict WEBB from licensing or selling
access to its XML Site Generation Platform, during the Exclusivity Period for
the following purposes:

     (a)  WEBB may, directly or indirectly through distribution partners,
          continue to offer and sell a service marketed to web site developers
          and/or graphic artists for the production of HTML web site pages (for
          Internet and Intranet applications) that also use XML technology, so
          long as the services are not made available to the following types of
          parties, as end-user customers, developers, or distribution partners:
          merchant aggregators, content syndication services, any yellow pages
          or other ad-based directory services, or any other Competitive
          Entities.  Throughout any Exclusivity Period, and to the extent that
          WEBB can contractually provide appropriate access, WEBB agrees to
          provide SB a client list and/or other means of promotional support, so
          that SB may market to such clients or prospects additional products
          and services.  In the event that SB provides products or services to a
          client or prospect as a result of obtaining such client list or
          support from WEBB, SB shall pay WEBB 50% of the Net Revenues
          recognized by SB from the sale of products or services to such client
          or prospect during the first six months of revenue generating services
          or product sales.

     (b)  WEBB may continue to offer and sell access to its XML Site Generation
          Platform as a component of custom solutions to websites that aggregate
          vertical single-category content, so long as: i) WEBB does not re-use
          any jointly created XML Definitions, Programmatic Interfaces, or

                                       7
<PAGE>

          integration processes which are unique to SB; ii) WEBB does not create

7.3  Minimum Payments; Termination or Extension of Exclusivity Period.  During
     ----------------------------------------------------------------
the first year of this Agreement, SB guarantees WEBB payments of $250,000 for
the quarters ending on September 30, 1999, December 31, 1999 and March 31, 2000,
such amounts to be due on the last day of the quarter and payable within 10 days

the quarters ending December 31, 1999 and March 31, 2000 by giving WEBB written
notice of its election to terminate such obligations by no later than August 14,
1999, in which event, SB's obligation to make such payments shall be terminated
and the Exclusivity Period shall terminate on September 30, 1999, rather than
June 30, 2000.  In the event that the Site Generation Platform Fees for the
quarters for which SB is obligated to make guaranteed payments exceed such

quarters ending December 31, 1999 and March 31, 2000, SB may extend the
Exclusivity Period for up to two additional successive one-year periods by
giving WEBB at least 90 days written notice prior to the end of the then current
Exclusivity Period that SB has elected to extend the Exclusivity Period for a
one-year period commencing on the following July 1 and by guaranteeing the

for such quarter are to be credited:

          quarter; and

     (ii) During the 12-month period commencing on July 1, 2001 -- $312,500 per
          quarter.

In the event that the Site Generation Platform Fees for the quarters for which
SB is obligated to make guaranteed payments exceed such guaranteed amounts, SB
will pay WEBB within thirty (30) days of the end of such quarter the difference
between the guaranteed amount for such quarter and the Site Generation Platform
Fees payable for such quarter.

Except in the event that SB terminates the initial Exclusivity Period effective
September 30, 1999, during any Exclusivity Period, SB shall be given a credit of
100% of the guaranteed payments during the applicable 12-month period to the
extent of Site Generation Platform Fees payable during such period.  In the
event of the early termination of the initial Exclusivity Period, SB shall be
given a credit of 100% of the guaranteed payments for the quarter ending
September 30, 1999 to the extent of Site Generation Platform Fees payable
through December 31, 1999.  In the event that SB does not elect to extend the

under applicable law.

the Exclusivity Period a performance bonus equal to 10 % of the difference
between (i) Net

                                      10
<PAGE>

Revenues recognized by SB from the sale of Vertical Template Sites and
enhancements thereto; and (ii) 150% of the average price paid by SB Customers
for Vertical Template Sites during each 12-month period of the Term of this
Agreement; where (i) is greater than (ii). SB shall make any payments due

          (provided that such Modifications do not cause a nonconformance with
          the applicable specifications), and to operate SB's own version of XML

     (c)  Promptly after the Perpetual License Grant and payment of the One Time
          Fee, WEBB will deliver to SB one copy of the Object Code and Source
          Code to the XML Site Generation Platform and SB will commence to host
          and operate, at its expense, the XML Site Generation Platform.  WEBB
          will provide, at no charge and on a timely basis, training and
          assistance reasonably required by SB to enjoy the benefits of its
          license rights pursuant to this Section 8.

          agreement, WEBB will not be obligated to develop Modifications that
          are unique to SB.

          provisions of Section 14.18(b), in the event of occurrence of any of
          the following events ("Release Events"): (i) SB terminates this
          Agreement in accordance with the provisions of Sections 4.11 or
          13.3(b); (ii) WEBB institutes a form of bankruptcy or similar
          proceeding that would result in WEBB's ceasing to operate as a going
          concern; (iii) WEBB commences the dissolution of WEBB that would
          result in WEBB's ceasing to operate as a going concern; or (iv) WEBB
          has not delivered the Source Code for the XML Site Generation Platform
          in accordance with the provisions of Section 8.1(c).

     (b)  The Escrow License Agreement shall grant SB a non-exclusive license to
          use, copy, and modify the XML Site Generation Platform Source Code for
          the purpose of (a) creating Web sites and Web site enhancements for SB
          Customers; (b) allowing SB Customers and SB's Contractors to access
          the XML Site Generation Platform (but not the Source Code) for the
          development, update, modification, and/or enhancement of Web sites for
          SB Customers or to access SB Customer account information; and (c) any
          other purposes for which SB is licensed to use the XML Site Generation
          Platform pursuant to this Agreement or for which WEBB is providing
          services pursuant to this Agreement at the time of the Release Event.
          The term of the Source Code license granted to SB hereunder shall be
          for the remainder of the Term if the Release Event is as stated in
          Section 14.18(a)(i), and shall be perpetual if the Release Event is as
          stated in Section 14.18(a)(ii) or (iii).

this Agreement:

     (a)  A Warrant for 150,000 shares of WEBB's common stock shall be granted

          Exclusivity Period effective September 30, 1999 as permitted in
          Section 7.3. The warrant shall be granted on the earlier of August 15,
          1999 or the date that SB waives its right to so terminate the
          Exclusivity Period, at an exercise price equal to 105% of the closing
          sale price for WEBB's common stock on the date of the grant as
          reported by The Nasdaq Stock Market, provided that if there is no sale
          of WEBB's common stock on such date, the last reported sale price
          prior to the date of grant; and

     (b)  A warrant for an additional 150,000 shares of WEBB's common stock
          shall be granted to SB provided that SB has been granted the warrant
          referred to above and provided further that SB and WEBB have entered
          into the Engineering Services Agreement dated as of June 30, 1999, and
          an agreement for the integration of WEBB's community building products

          granted on the date that all of the foregoing conditions have been
          satisfied at an exercise price equal to 105% of the closing sale price
          for WEBB's common stock on the date of grant as reported by The Nasdaq
          Stock Market, provided that if there is no sale of WEBB's common stock
          on such date, the last reported sale price prior to the date of grant.

     (c)  An appropriate adjustment shall be made in the number of shares of
          WEBB common stock to be subject to such warrants in the event that
          WEBB pays a dividend on its shares of common stock in common stock,
          subdivides or combines its shares of common stock or makes any other
          such change in its capital structure prior to the grant of the
          warrants.

                          PREFERRED ESCROW AGREEMENT

                     Account Number ______________________


This Agreement is effective __________________, 19_____ among Data Securities
International, Inc. ("DSI"), ______________________________________
("Depositor") and ______________________________________ ("Preferred
Beneficiary"), who collectively may be referred to in this Agreement as "the
parties."

A.   Depositor and Preferred Beneficiary have entered into a Development and
Access and License Agreement, dated June 30, 1999, (referred to in this
Agreement as "the license agreement").

B.   Depositor desires to avoid disclosure of its proprietary technology except
under certain limited circumstances.

C.   The availability of the proprietary technology of Depositor is critical to
Preferred Beneficiary in the conduct of its business and, therefore, Preferred
Beneficiary needs access to the proprietary technology under certain limited
circumstances.

D.   Depositor and Preferred Beneficiary desire to establish an escrow with DSI
to provide for the retention, administration and controlled access of the
proprietary technology materials of Depositor.


ARTICLE 1  --  DEPOSITS

1.1    Obligation to Make Deposit.  Upon the signing of this Agreement by the
       --------------------------
parties, Depositor shall deliver to DSI the proprietary information and other
materials ("deposit materials") required to be deposited by the license
agreement or, if the license agreement does not identify the materials to be
deposited with DSI, then such materials will be identified on an Exhibit D-1.
If Exhibit D-1 is applicable, it is to be prepared and signed by Depositor and
Preferred Beneficiary.  DSI shall have no obligation with respect to the
preparation, signing or delivery of Exhibit D-1.

1.2    Identification of Tangible Media.  Prior to the delivery of the deposit
       --------------------------------
materials to DSI, Depositor shall conspicuously label for identification each
document, magnetic tape, disk, or other tangible media upon which the deposit
materials are written or stored. Additionally, Depositor shall complete Exhibit
D-2 to this Agreement by listing each such tangible media by the item label
description, the type of media and the quantity.  The Exhibit D-2 must be signed
by Depositor and delivered to DSI with the deposit materials.  Unless and until
Depositor makes the initial deposit with DSI, DSI shall have no obligation with
respect to this Agreement, except the obligation to notify the parties regarding
the status of the deposit account as required in Section 2.2 below.

1.3    Deposit Inspection.  When DSI receives the deposit materials and the
       ------------------
Exhibit D-2, DSI will conduct a deposit inspection by visually matching the
labeling of the tangible media containing the deposit materials to the item
descriptions and quantity listed on the Exhibit D-2.  In addition to the deposit
inspection, Preferred Beneficiary may elect to cause a verification of the
deposit materials in accordance with Section 1.6 below.

1.4    Acceptance of Deposit.   At completion of the deposit inspection, if DSI
       ---------------------
determines that the labeling of the tangible media matches the item descriptions
and quantity on Exhibit D-2, DSI will date and sign the Exhibit D-2 and mail a
copy thereof to Depositor and Preferred Beneficiary.  If DSI determines that the
labeling does not match the item descriptions or quantity on the Exhibit D-2,
DSI will (a) note the discrepancies in writing on the Exhibit D-2; (b) date and
sign the Exhibit D-2 with the exceptions noted; and (c) provide a copy of the
Exhibit D-2 to Depositor and Preferred Beneficiary.  DSI's acceptance of the
deposit occurs upon the signing of the Exhibit D-2 by

                                      D-1
<PAGE>

DSI. Delivery of the signed Exhibit D-2 to Preferred Beneficiary is Preferred
Beneficiary's notice that the deposit materials have been received and accepted
by DSI.

1.5    Depositor's Representations.  Depositor represents as follows:
       ---------------------------

       a.   Depositor lawfully possesses all of the deposit materials deposited
            with DSI;

       b.   With respect to all of the deposit materials, Depositor has the
            right authority to grant to DSI and Preferred Beneficiary the rights
            as provided in this Agreement;

       c.   The deposit materials are not subject to any lien or other
            encumbrance;

       d.   The deposit materials consist of the proprietary information and
            other identified either in the license agreement or Exhibit D-1, as
            the case may be; and

       e.   The deposit materials are readable and useable in their current form
            or, if the deposit materials are encrypted, the decryption tools and
            decryption keys have also been deposited.

1.6    Verification.  Preferred Beneficiary shall have the right, at Preferred
       ------------
Beneficiary's expense, to cause a verification of any deposit materials.  A
verification determines, in different levels of detail, the accuracy,
completeness, sufficiency and quality of the deposit materials.  If a
verification is elected after the deposit materials have been delivered to DSI,
then only DSI, or at DSI's election an independent person or company selected
and supervised by DSI, may perform the verification.

1.7    Deposit Updates.  Unless otherwise provided by the license agreement,
       ---------------
Depositor shall update the deposit materials within 60 days of each release of a
new version of the product which is subject to the license agreement.  Such
updates will be added to the existing deposit.  All deposit updates shall be
listed on a new Exhibit D-2 and the new Exhibit D-2 shall be signed by
Depositor.  Each Exhibit D-2 will be held and maintained separately within the
escrow account.  An independent record will be created which will document the
activity for each Exhibit D-2.  The processing of all deposit updates shall be
in accordance with Sections 1.2 through 1.6 above.  All references in this
Agreement to the deposit materials shall include the initial deposit materials
and any updates.

1.8    Removal of Deposit Materials. The deposit materials may be removed and/or
       ----------------------------
exchanged only on written instructions signed by Depositor and Preferred
Beneficiary, or as otherwise provided in this Agreement.

ARTICLE 2  -- CONFIDENTIALITY AND RECORD KEEPING

2.1    Confidentiality.  DSI shall maintain the deposit materials in a secure,
       ---------------
environmentally safe, locked facility which is accessible only to authorized
representatives of DSI.  DSI shall have the obligation to reasonably protect the
confidentiality of the deposit materials.  Except as provided in this Agreement,
DSI shall not disclose, transfer, make available, or use the deposit materials.
DSI shall not disclose the content of this Agreement to any third party.  If DSI
receives a subpoena or other order of a court or other judicial tribunal
pertaining to the disclosure or release of the deposit materials, DSI will
immediately notify the parties to this Agreement.  It shall be the
responsibility of Depositor and/or Preferred Beneficiary to challenge any such
order; provided, however, that DSI does not waive its rights to present its
position with respect to any such order.  DSI will not be required to disobey
any court or other judicial tribunal order.  (See Section 7.5 below for notices
of requested orders.)

2.2    Status Reports.  DSI will issue to Depositor and Preferred Beneficiary a
       --------------
report profiling the account history at least semi-annually.  DSI may provide
copies of the account history pertaining to this Agreement upon the request of
any party to this Agreement.

2.3    Audit Rights.  During the Term of this Agreement, Depositor and Preferred
       ------------
Beneficiary shall each have the right to inspect the written records of DSI
pertaining to this Agreement.  Any inspection shall be held during normal
business hours and following reasonable prior notice.

                                      D-2
<PAGE>

ARTICLE 3  --  GRANT OF RIGHTS TO DSI

3.1    Title to Media.  Depositor hereby transfers to DSI the title to the media
       --------------
upon which the proprietary information and materials are written or stored.
However, this transfer does not include the ownership of the proprietary
information and materials contained on the media such as any copyright, trade
secret, patent or other intellectual property rights.

3.2    Right to Make Copies.  DSI shall have the right to make copies of the
       --------------------
deposit materials as reasonably necessary to perform this Agreement.  DSI shall
copy all copyright, nondisclosure, and other proprietary notices and titles
contained on the deposit materials onto any copies made by DSI.  With all
deposit materials submitted to DSI, Depositor shall provide any and all
instructions as may be necessary to duplicate the deposit materials including
but not limited to the hardware and/or software needed.

3.3    Right to Transfer Upon Release. Depositor hereby grants to DSI the right
       ------------------------------
to transfer the deposit materials to Preferred Beneficiary upon any release of
the deposit materials for use by Preferred Beneficiary in accordance with
Section 4.5. Except upon such a release or as otherwise provided in this
Agreement, DSI shall not transfer the deposit materials.

ARTICLE 4  -- RELEASE OF DEPOSIT

4.1    Release Conditions. As used in this Agreement, "Release Conditions" shall
       ------------------
mean the following:

       (i)   Preferred Beneficiary's termination of the license agreement in
             accordance with the provisions of Sections 4.11 or 13.3(b) thereof;

       (ii)  Depositor institutes a form of bankruptcy or similar proceeding
             that would result in Depositor's ceasing to operate as a going
             concern;

       (iii) Depositor commences the dissolution of Depositor that would result
             in Depositor's ceasing to operate as a going concern; or

       (iv)  WEBB has not delivered the Source Code for the XML Site Generation
             Platform in accordance with the provisions of Section 8.1(c) of the
             license agreement.

4.2    Filing For Release. If Preferred Beneficiary believes in good faith that
       ------------------
a Release Condition has occurred, Preferred Beneficiary may provide to DSI
written notice of the occurrence of the Release Condition and a request for the
release of the deposit materials. Upon receipt of such notice, DSI shall provide
a copy of the notice to Depositor, by certified mail, return receipt requested,
or by commercial express mail.

4.3    Contrary Instructions.  From the date DSI mails the notice requesting
       ---------------------
release of the deposit materials, Depositor shall have ten business days to
deliver to DSI Contrary Instructions. "Contrary Instructions" shall mean the
written representation by Depositor that a Release Condition has not occurred or
has been cured.  Upon receipt of Contrary Instructions, DSI shall send a copy to
Preferred Beneficiary by certified mail, return receipt requested, or by
commercial express mail.  Additionally, DSI shall notify both Depositor and
Preferred Beneficiary that there is a dispute to be resolved pursuant to the
Dispute Resolution section (Section 7.3) of this Agreement.  Subject to Section
5.2, DSI will continue to store the deposit materials without release pending
(a) joint instructions from Depositor and Preferred Beneficiary; (b) resolution
pursuant to the Dispute Resolution provisions; or (c) order of a court.

4.4    Release of Deposit. If DSI does not receive Contrary Instructions from
       ------------------
the Depositor, DSI is authorized to release the deposit materials to the
Preferred Beneficiary or, if more than one beneficiary is registered to the
deposit, to release a copy of the deposit materials to the Preferred
Beneficiary. However, DSI is entitled to receive any fees

                                      D-3
<PAGE>

due DSI before making the release. This Agreement will terminate upon the
release of the deposit materials held by DSI.

4.5    Right to Use Following Release.  Unless otherwise provided in the license
       ------------------------------
agreement, upon release of the deposit materials in accordance with this Article
4, Preferred Beneficiary shall have the nonexclusive right to use the deposit
materials for the sole purpose of continuing the benefits afforded to Preferred
Beneficiary by the license agreement.  Preferred Beneficiary shall be obligated
to maintain the confidentiality of the released deposit materials.

ARTICLE 5  --  TERM AND TERMINATION

5.1    Term of Agreement.  The Term of this Agreement shall be equal to the term
       -----------------
       of the license agreement.

5.2    Termination for Nonpayment. In the event of the nonpayment of fees owed
       --------------------------
to DSI, DSI shall provide written notice of delinquency to all parties to this
Agreement. Any party to this Agreement shall have the right to make the payment

DSI within one month of the date of such notice, then DSI shall have the right

agreement with DSI.

5.4    Survival of Terms Following Termination.  Upon termination of this
       ---------------------------------------
Agreement, the following provisions of this Agreement shall survive:

            materials;

            Release (Section 3.3) and Right to Use Following Release (Section

       d.   The obligation to pay DSI any fees and expenses due;

       e.   The provisions of Article 7; and

6.1     Fee Schedule.  DSI is entitled to be paid its standard fees and expenses
        ------------
applicable to the services provided.  DSI shall notify the Preferred

schedule, DSI will provide a quote prior to rendering the service, if requested.

6.2     Payment Terms.  DSI shall not be required to perform any service unless
        -------------
the payment for such service and any outstanding balances owed to DSI are paid
in full. Fees are due upon receipt of a signed contract or receipt of the
deposit materials whichever is earliest. If invoiced fees are not paid, DSI may
terminate this Agreement in

                                      D-4
<PAGE>

accordance with Section 5.2. Late fees on past due amounts shall accrue interest
at the rate of one and one-half percent per month (18% per annum) from the date

ARTICLE 7  --  LIABILITY AND DISPUTES

7.1    Right to Rely on Instructions.  DSI may act in reliance upon any
       -----------------------------
instruction, instrument, or signature reasonably believed by DSI to be genuine.
DSI may assume that any employee of a party to this Agreement who gives any
written notice, request, or instruction has the authority to do so.  DSI shall
not be responsible for failure to act as a result of causes beyond the
reasonable control of DSI.

7.2    Indemnification. DSI shall be responsible to perform its obligations
       ---------------
under this Agreement and to act in a reasonable and prudent manner with regard
to this escrow arrangement. Provided DSI has acted in the manner stated in the
preceding sentence, Depositor and Preferred Beneficiary each agree to indemnify,
defend and hold harmless DSI from any and all claims, actions, damages,
arbitration fees and expenses, costs, attorney's fees and other liabilities
incurred by DSI relating in any way to this escrow arrangement.

7.3    Dispute Resolution. Any dispute relating to or arising from this
       ------------------
Agreement shall be resolved in the same manner as provided in Section 14.2 of
the license agreement.

7.4    Controlling Law.  This Agreement is to be governed and construed in
       ---------------
accordance with the laws of the State of California, without regard to its
conflict of law provisions.

7.5    Notice of Requested Order.  If any party intends to obtain an order from

take, or refrain from taking any action, that party shall:

       a.    Give DSI at least two business days' prior notice of the hearing;

       b.    Include in any such order that, as a precondition to DSI's
             obligation, DSI be paid in full for any past due fees and be paid
             for the reasonable value of the services to be rendered pursuant to
             such order; and

       c.    Ensure that DSI not be required to deliver the original (as opposed
             to a copy) of the deposit materials if DSI may need to retain the
             original in its possession to fulfill any of its other duties.

ARTICLE 8  --  GENERAL PROVISIONS

8.1    Entire Agreement.  This Agreement, which includes the Exhibits described
       ----------------
herein, embodies the entire understanding among the parties with respect to its
subject matter and supersedes all previous communications, representations or
understandings, either oral or written. DSI is not a party to the license
agreement between Depositor and Preferred Beneficiary and has no knowledge of
any of the terms or provisions of any such license agreement.  DSI's only
obligations to Depositor or Preferred Beneficiary are as set forth in this
Agreement. No amendment or modification of this Agreement shall be valid or
binding unless signed by all the parties hereto, except that Exhibit D-1 need
not be signed by DSI, Exhibit D-2 need not be signed by Preferred Beneficiary
and Exhibit D-3 need not be signed.

8.2    Notices. All notices, invoices, payments, deposits and other documents
       -------
and communications shall be given to the parties at the addresses specified in
the attached Exhibit D-3. It shall be the responsibility of the parties to
notify each other as provided in this Section in the event of a change of
address. The parties shall have the right to rely on the last known address of
the other parties. Unless otherwise provided in this Agreement, all documents
and communications may be delivered by First Class mail.

8.3    Severability. In the event any provision of this Agreement is found to be
       ------------
invalid, voidable or unenforceable, the parties agree that unless it materially
affects the entire intent and purpose of this Agreement, such invalidity,
voidability or unenforceability shall affect neither the validity of this
Agreement nor the remaining

                                      D-5
<PAGE>

provisions herein, and the provision in question shall be deemed to be replaced
with a valid and enforceable provision most closely reflecting the intent and
purpose of the original provision.

8.4    Successors.  This Agreement shall be binding upon and shall inure to the
       ----------
benefit of the successors and assigns of the parties.  However, DSI shall have
no obligation in performing this Agreement to recognize any successor or assign
of Depositor or Preferred Beneficiary unless DSI receives clear, authoritative
and conclusive written evidence of the change of parties.

     Online System Services, Inc., a Colorado corporation, hereby certifies
that, for value received, Switchboard, Inc., whose address is 115 Flanders Road,
Westboro, MA 01581, or its registered assigns (the "Registered Holder"), is
entitled, subject to the terms set forth below, to purchase from the Company at
any time or .from time to time on or before 5:00 P.M. Denver time, June 30, 2002
(such time, the "Expiration Time"), 150,000 of the Company's fully paid and
nonassessable shares of Common Stock at the purchase price per share of $_______
(the "Purchase Price").  The number and character of such Common Stock and the
Purchase Price are subject to adjustment as provided herein.

     This Warrant is a warrant to purchase Common Stock (the "Warrant") of the
Company, contemplated by the Development, Access and License Agreement (the
"Agreement"), dated June 30, 1999 between the Company and Switchboard, Inc.
This Warrant, and any additional warrant issued pursuant to the Agreement are
referred to herein collectively as the "Agreement Warrants."

     As used herein the following terms, unless the context otherwise requires,
have the following respective meanings:

          (a) The term "Company" means Online System Services, Inc. and also
     includes any corporation which shall succeed to or assume the obligations
     of Online System Services, Inc. hereunder.

          (b) The term "Common Stock" includes the Company's shares of common
     stock, no par value, and also includes all shares of any class or classes
     (however designated) of the Company, authorized on or after the date
     hereof, the holders of which shall have the right, without limitation as to
     amount, either to all or to a share of the balance of current dividends and
     liquidating dividends after the payment of dividends and distributions on
     any shares entitled to preference, and the holders of which shall
     ordinarily be entitled to vote for the election of directors of the Company
     (even though the right so to vote has been suspended by the happening of a
     contingency).
<PAGE>

          (c) The term "Other Securities" refers to any class of shares (other
     than Common Stock) and other securities of the Company or any other person
     (corporate or otherwise) which the holders of the Warrants at any time
     shall be entitled to receive, or shall have received, upon the exercise of
     the Warrants, in lieu of or in addition to Common Stock, or which at any
     time shall be issuable or shall have been issued in exchange for or in
     replacement of Common Stock or Other Securities pursuant to Section 6 or
     otherwise.

          (d) The term "Shares" means the Common Stock issued or issuable upon
     exercise of this Warrant.

1.   Registration Rights.  At any time after _____________, 2000 [ten months
from the grant of the first of the Agreement Warrants issued], that Registered
Holders of 50% or more of the shares of the Common Stock subject to the
Agreement Warrants plus any shares of Common Stock issued pursuant to the
exercise of the Agreement Warrants (all such shares of Common Stock and the
Registered Holders thereof being referred to herein as the "Registerable
Securities" and "Securities Holders," respectively) make a written request that
the Registerable Securities be registered pursuant to the registration
requirements of the Securities Act of 1933, as amended (the "Securities Act"),
the Company will prepare and file with the Securities and Exchange Commission
one registration statement relating to the Registerable Securities as are
requested to be included in such registration statement.  The Company will file
the registration statement within 45 days of receipt of the written request and
will use its best efforts to see that the registration statement is declared
effective by the Securities and Exchange Commission as soon as practicable
thereafter.  The Company will also use reasonable best efforts to (i) register
and qualify the Registerable Securities covered by the registration statement
under such other securities or blue sky laws of such jurisdictions as the
Securities Holders who hold a majority in interest of the Registerable
Securities being offered may reasonably request; and (ii) see that the
registration statement remain effective with the Securities and Exchance
Commission until the earlier of ________________, 2002 [three years from the
grant date of the first of the Agreement Warrants issued] or the date upon which
all of the Registerable Securities have been sold by the Securities Holders.

     As a condition to the inclusion of any shares of Common Stock in the
registration statement, the Company may require that all Securities Holders
desiring to include shares in the registration enter into an agreement with the
Company and the other such Securities Holders, whereby the Securities Holders
shall agree that as a group, notwithstanding the registration statement, they
will not sell during any period a number of shares of Common Stock which would
exceed the quantity limitations of Rule 144 promulgated by the Securities and
Exchange Commission, assuming for this purpose that they were acting in concert
and that they had acquired their shares of Common Stock as of the grant date of
the first of the Agreement Warrants issued.  It shall be a further condition
precedent to the obligations of the Company to complete the registration
pursuant to this Warrant that each Securities Holder shall furnish to the
Company such information regarding itself and the Company's securities and the
intended method of disposition of the Registerable Securities held by it, as
shall be reasonably required to affect the registration of the Registerable
Securities, and each such Securities Holder shall execute such documents in
connection with such registration as the Company may reasonably request.

     Upon receipt of any request for registration pursuant to this Section 1,
the Company shall promptly give written notice of such proposed registration to
all other Registered Holder.  Each Registered Holders shall have the right, by
giving written notice to the Company within 10 days after the Company provides
its notice, to elect to have included in such registration such of their
Registrable Securities as such holders may request in such notice of election,.
Thereupon, the Company shall, as expeditiously as possible, use its best efforts
to effect the registration on an appropriate registration form of all
Registrable Securities which the Company has been requested to so register.

     If and whenever the Company is required by the provisions of this Warrant
to effect the registration of any Registrable Securities under the Securities
Act, the Company shall:

          (i)    file with the Commission a Registration Statement with respect
     to such Registrable Securities;

          (ii)   as expeditiously as possible prepare and file with the
     Commission any amendments and supplements to the Registration Statement and
     the prospectus included in the Registration Statement as may be necessary
     to comply with the provisions of the Securities Act (including the anti-
     fraud provisions
<PAGE>

     thereof) and to keep the Registration Statement effective until the time
     specified above or such lesser period until all such Registrable Securities
     are sold;

          (iii)  as expeditiously as possible furnish to each person including
     Registrable Securities in the Registration Statement ("Selling
     Stockholders") such reasonable numbers of copies of the Prospectus,
     including any preliminary Prospectus, in conformity with the requirements
     of the Securities Act, and such other documents as such Selling Stockholder
     may reasonably request in order to facilitate the public sale or other
     disposition of the Registrable Securities owned by such Selling
     Stockholder;

          (iv)   as expeditiously as possible use its best efforts to register
     or qualify the Registrable Securities covered by the Registration Statement
     under the securities or Blue Sky laws of such states as the Selling
     Stockholders shall reasonably request, and do any and all other acts and
     things that may be necessary or desirable to enable the Selling
     Stockholders to consummate the public sale or other disposition in such
     states of the Registrable Securities owned by the Selling Stockholder;

          (v)    as expeditiously as possible, cause all such Registrable
     Securities to be listed on each securities exchange or automated quotation
     system on which similar securities issued by the Company are then listed;

          (vi)   promptly make available for inspection by the Selling
     Stockholders and any attorney or accountant or other agent retained by any
     such underwriter or selected by the Selling Stockholders, all financial and
     other records, pertinent corporate documents and properties of the Company
     and cause the Company's officers, directors, employees and independent
     accountants to supply all information reasonably requested by any such
     seller, underwriter, attorney, accountant or agent in connection with such
     Registration Statement;

          (vii)  as expeditiously as possible, notify each Selling Stockholder,
     promptly after it shall receive notice thereof, of the time when such

     and

          (viii) as expeditiously as possible following the effectiveness of
     such Registration Statement, notify each seller of such Registrable
     Securities of any request by the Commission for the amending or
     supplementing of such Registration Statement or Prospectus.

     If the Company has delivered a Prospectus to the Selling Stockholders and
after having done so the Prospectus is amended to comply with the requirements
of the Securities Act, the Company shall promptly notify the Selling
Stockholders and, if requested, the Selling Stockholders shall immediately cease
making offers of Registrable Securities and return all Prospectuses to the
Company.  The Company shall promptly provide the Selling Stockholders with
revised Prospectuses and, following receipt of the revised Prospectuses, the
Selling Stockholders shall be free to resume making offers of the Registrable
Securities.

     The Company will pay all Registration Expenses for all registrations under
this Agreement.  For purposes of this Section, the term "Registration Expenses"
shall mean all expenses incurred by the Company in complying with this
Agreement, including, without limitation, all registration and filing fees,

Stockholders' own counsel.

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

          (a)    In the event of any registration of any of the Registrable
     Securities under the Securities Act pursuant to this Warrant, the Company
     will indemnify and hold harmless each Selling Stockholder, each underwriter
     of such Registrable Securities, and each other person, if any, who controls
     such Selling Stockholder or underwriter within the meaning of the
     Securities Act or the Securities Exchange Act of 1934, as amended (the
     "Exchange Act") against any losses, claims, damages or liabilities, joint
     or several, to which such Selling Stockholder, underwriter or controlling
     person may become subject under the Securities Act, the Exchange Act, state
     securities or Blue Sky laws or otherwise, insofar as such losses,
<PAGE>

     claims, damages or liabilities (or actions in respect thereof) arise out of
     or are based upon any untrue statement or alleged untrue statement of any
     material fact contained in any Registration Statement under which such
     Registrable Securities were registered under the Securities Act, any
     preliminary prospectus or final prospectus contained in the Registration
     Statement, or any amendment or supplement to such Registration Statement,
     or arise out of or are based upon the omission or alleged omission to state
     a material fact required to be stated therein or necessary to make the
     statements therein not misleading; and the Company will reimburse such
     Selling Stockholder, underwriter and each such controlling person for any
     legal or any other expenses reasonably incurred by such Selling
     Stockholder, underwriter or controlling person in connection with
     investigating or defending any such loss, claim, damage, liability or
     action; provided, however, that the Company will not be liable in any such
             -----------------
     case to the extent that any such loss, claim, damage or liability arises
     out of or is based upon any untrue statement or omission made in such
     Registration Statement, preliminary prospectus or prospectus, or any such
     amendment or supplement, in reliance upon and in conformity with
     information furnished to the Company, in writing, by or on behalf of such
     Selling Stockholder, underwriter or controlling person specifically for use
     in the preparation thereof.

          (b)    In the event of any registration of any of the Registrable
     Securities under the Securities Act pursuant to this Warrant, each Selling
     Stockholder, severally and not jointly, will indemnify and hold harmless
     the Company, each of its directors and officers and each underwriter (if
     any) and each person, if any, who controls the Company or any such
     underwriter within the meaning of the Securities Act or the Exchange Act,
     against any losses, claims, damages or liabilities, joint or several, to
     which the Company, such directors and officers, underwriter or controlling
     person may become subject under the Securities Act, Exchange Act, state
     securities or Blue Sky laws or otherwise, insofar as such losses, claims,
     damages or liabilities (or actions in respect thereof) arise out of or are
     based upon any untrue statement or alleged untrue statement of a material
     fact contained in any Registration Statement under which such Registrable
     Securities were registered under the Securities Act, any preliminary
     prospectus or final prospectus contained in the Registration Statement, or
     any amendment or supplement to the Registration Statement, or arise out of
     or are based upon any omission or alleged omission to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, if the statement or omission was made in reliance upon and
     in conformity with information relating to such Selling Stockholder
     furnished in writing to the Company by or on behalf of such Selling
     Stockholder specifically for use in connection with the preparation of such
     Registration Statement, prospectus, amendment or supplement; provided,
                                                                  --------
     however, that the obligations of a Selling Stockholder hereunder shall be
     -------
     limited to an amount equal to the net proceeds to such Selling Stockholder
     of Registrable Securities sold in connection with such registration.

          (c)    Each party entitled to indemnification under this Section (the
     "Indemnified Party") shall give notice to the party required to provide
     indemnification (the "Indemnifying Party") promptly after such Indemnified
     Party has actual knowledge of any claim as to which indemnity may be
     sought, and shall permit the Indemnifying Party to assume the defense of
     any such claim or any litigation resulting therefrom; provided, that
                                                           --------
     counsel for the Indemnifying Party, who shall conduct the defense of such
     claim or litigation, shall be approved by the Indemnified Party (whose
     approval shall not be unreasonably withheld); and, provided, further, that
                                                        --------  -------
     the failure of any Indemnified Party to give notice as provided herein
     shall not relieve the Indemnifying Party of its obligations under this
     Section except to the extent that the Indemnifying Party is adversely
     affected by such failure. The Indemnified Party may participate in such
     defense at such party's expense; provided, however, that the Indemnifying
                                      --------  -------
     Party shall pay such expense if representation of such Indemnified Party by
     the counsel retained by the Indemnifying Party would be inappropriate due
     to actual or potential differing interests between the Indemnified Party
     and any other party represented by such counsel in such proceeding;
     provided further that in no event shall the Indemnifying Party be required
     -------- -------
     to pay the expenses of more than one law firm per jurisdiction as counsel
     for the Indemnified Party.  The Indemnifying Party also shall be
     responsible for the expenses of such defense if the Indemnifying Party does
     not elect to assume such defense.  No Indemnifying Party, in the defense of
     any such claim or litigation shall, except with the consent of each
     Indemnified Party, consent to entry of any judgment or enter into any
     settlement which does not include as an unconditional term thereof the
     giving by the claimant or plaintiff to such Indemnified Party of a release
     from all liability in respect of such claim or litigation, and no
     Indemnified Party shall consent to entry of any judgment or settle such
     claim or litigation without the prior written consent of the Indemnifying
     Party, which consent shall not be unreasonably withheld.
<PAGE>

          (d)    In order to provide for just and equitable contribution in
     circumstances in which the indemnification provided for in this Section is
     due in accordance with its terms but for any reason is held to be
     unavailable to an Indemnified Party in respect to any losses, claims,
     damages and liabilities referred to herein, then the Indemnifying Party
     shall, in lieu of indemnifying such Indemnified Party, contribute to the
     amount paid or payable by such Indemnified Party as a result of such
     losses, claims, damages or liabilities to which such party may be subject
     in such proportion as is appropriate to reflect the relative fault of the
     Company on the one hand and the Selling Stockholders on the other in
     connection with the statements or omissions which resulted in such losses,
     claims, damages or liabilities, as well as any other relevant equitable
     considerations.  The relative fault of the Company and the Selling
     Stockholders shall be determined by reference to, among other things,
     whether the untrue or alleged untrue statement of material fact related to
     information supplied by the Company or the Selling Stockholders and the
     parties' relative intent, knowledge, access to information and opportunity
     to correct or prevent such statement or omission.  The Company and the
     Selling Stockholders agree that it would not be just and equitable if
     contribution pursuant to this Section were determined by pro rata
     allocation or by any other method of allocation which does not take account
     of the equitable considerations referred to above.  Notwithstanding the
     provisions of this paragraph of this Section, (a) in no case shall any one
     Selling Stockholder be liable or responsible for any amount in excess of
     the net proceeds received by such Selling Stockholder from the offering of
     Registrable Securities and (b) the Company shall be liable and responsible
     for any amount in excess of such proceeds; provided, however, that no
                                                --------  -------
     person guilty of fraudulent misrepresentation (within the meaning of
     Section 11(f) of the Securities Act) shall be entitled to contribution from
     any person who was not guilty of such fraudulent misrepresentation.  Any
     party entitled to contribution will, promptly after receipt of notice of
     commencement of any action, suit or proceeding against such party in
     respect of which a claim for contribution may be made against another party
     or parties under this Section, notify such party or parties from whom
     contribution may be sought, but the omission so to notify such party or
     parties from whom contribution may be sought shall not relieve such party
     from any other obligation it or they may have thereunder or otherwise under
     this Section.  No party shall be liable for contribution with respect to
     any action, suit, proceeding or claim settled without its prior written
     consent, which consent shall not be unreasonably withheld.

2.   Transfer Restriction.  The Registered Holder acknowledges that (i) neither
this Warrant nor the Shares have been registered under the Securities Act and
may not be transferred unless (a) subsequently registered thereunder or (b) the
Registered Holder shall have delivered to the Company an opinion of counsel,
reasonably satisfactory in form and substance to the Company, to the effect that
the Warrant or Shares to be sold or transferred may be sold or transferred
pursuant to an exemption from such registration, (ii) any sale or transfer of
this Warrant or the Shares made in reliance upon Rule 144 under the Securities
Act may be made only in accordance with the terms of Rule 144 and, if Rule 144
is not applicable, any resale of this Warrant or the Shares under circumstances
in which the seller, or the person through whom the sale is made, may be deemed
to be an underwriter, as that term is used in the Securities Act, may require
compliance with another exemption under the Securities Act and the rules and
regulations promulgated thereunder, and (iii) neither the Company nor any other
person is under any obligation to comply with the terms and conditions of any
exemption under the Securities Act or the rules and regulations promulgated
thereunder.  The Registered Holder acknowledges that this Warrant and the
certificate for the Shares may bear an appropriate legend describing the
transfer restrictions and may be subject to a stop-transfer order placed against
the transfer of this Warrant or the Shares.

     Notwithstanding the foregoing, no registration or opinion of counsel shall
be required for (i) a transfer of all of this Warrant and any and all Shares to
any affiliate (as defined in Rule 12b-2 under the Exchange Act, an "Affiliate")
of the Registered Holder; (ii) a transfer made in accordance with Rule 144 under
the Securities Act; and (iii) a transfer which Company consents to in writing.

3.   Exercise of Warrant.

     3.1. Exercise in Full.  The holder of this Warrant may exercise it in full
          ----------------
prior to the Expiration Time by surrendering to the Company this Warrant
together with the form of Election to Purchase attached hereto as Annex A duly
                                                                  -------
executed by such holder.  Such exercise may be accomplished by faxing an
executed and completed Election to Purchase to the Company and delivering,
within three business days thereafter, the original Election to Purchase and
Warrant via hand delivery or overnight courier.  Such exercise shall be deemed
to have occurred on the date on
<PAGE>

which the facsimile copy of the Election to Purchase was received by the
Company. The surrendered Warrant shall be accompanied by payment, in cash or by
certified or official bank check payable to the order of the Company, in the
amount obtained by multiplying the number of Shares of Common Stock called for
on the face of this Warrant (after giving effect to any adjustment provided for
in this Warrant) by the Purchase Price, as adjusted.

     3.2. Partial Exercise.  This Warrant may be exercised in part by surrender
          ----------------
of this Warrant in the manner provided in Section 3.1, except that the exercise
price shall be calculated by multiplying (a) the number of shares of Common
Stock as shall be designated by the holder in the form of Election of Purchase
by (b) the Purchase Price, as adjusted.  On any such partial exercise, subject
to the provisions of Section 2 hereof, the Company, at its expense, will issue
and deliver to or upon the order of the Registered Holder hereof a new Warrant
or Warrants of like tenor, in the name of the Registered Holder hereof or as
such Registered Holder may request, calling in the aggregate on the face or
faces thereof for the number of shares of Common Stock (after giving effect to
any adjustment provided for in this Warrant) equal to the number of such shares
called for on the face of this Warrant minus the number of such shares
designated by the Registered Holder in the applicable Election to Purchase.

4.   Delivery of Share Certificates upon Exercise.  Following the exercise of
this Warrant in full or in part, within the time periods and in the manner
provided in this Warrant, the Company, at its expense (including the payment by
it of any applicable issue taxes), will cause to be issued in the name of and
delivered to the Registered Holder hereof, or as such Registered Holder (upon
payment by such Registered Holder of any applicable transfer taxes) may direct,
a certificate or certificates for the number of fully paid and nonassessable
shares of Common Stock to which such Registered Holder shall be entitled on such
exercise, plus, in lieu of any fractional share to which such Registered Holder
would otherwise be entitled, cash equal to such fraction multiplied by the then
current market value of one full share of Common Stock (as computed in
accordance with Subsection 5.1(c) of this Warrant).

5.   Adjustment of Purchase Price and Number of Shares of Common Stock.

     5.1. Adjustment of Purchase Price.  The Purchase Price hereof shall be
          ----------------------------
subject to adjustment from time to time as follows:

          (a)    If the Company (i) pays a dividend on its shares of Common
     Stock in Common Stock, (ii) subdivides its outstanding shares of Common
     Stock or (iii) combines its then outstanding shares of Common Stock into a
     smaller number of shares of Common Stock, then the Purchase Price in effect
     immediately prior thereto shall be adjusted proportionately so that the
     adjusted Purchase Price will bear the same relation to the Purchase Price
     in effect immediately prior to any such event as the total number of shares
     of Common Stock outstanding immediately prior any such event shall bear to
     the total number of shares of Common Stock outstanding immediately after
     such event. An adjustment made pursuant to this Section 5.1(a) shall, (i)
     become effective retroactively immediately after the record date in the
     case of a dividend and shall (ii) become effective immediately after the
     effective date in the case of a subdivision or combination. The Purchase
     Price, as so adjusted, shall be readjusted in the same manner upon the
     happening of any successive event or events described herein.

          (b)    If the Company distributes to all holders of its shares of
     Common Stock, (i) Other Securities, (ii) evidences of its indebtedness or
     assets (excluding cash dividends or distributions) or (iii) purchase
     rights, options or warrants to subscribe for or purchase Other Securities,
     then the Purchase Price in effect thereafter shall be determined by
     multiplying the Purchase Price in effect immediately prior to any such
     event by a fraction, the numerator of which shall be the total number of
     outstanding shares of Common Stock multiplied by the current market price
     per share of Common Stock (determined in accordance with the provisions of
     Section 5.1(c) of this Warrant) on the record date mentioned below, less
     the fair market value (as determined by the Board of Directors, whose
     determination shall be conclusive) of the Other Securities, evidences of
     indebtedness or assets, or the rights, options or warrants so distributed,
     and the denominator of which shall be the total number of outstanding
     shares of Common Stock multiplied by such current market price per share of
     Common Stock. Such adjustment shall be made whenever any such distribution
     is made and shall become effective retroactively immediately after the
     record date for the determination of shareholders entitled to receive such
     distribution.
<PAGE>

          (c) For the purpose of any computation under subdivision (b) above,
     the current market price per share of Common Stock shall be deemed to be
     the closing price of the Company's shares of Common Stock on the date that
     the computation is made.

          (d) No adjustment of the Purchase Price shall be made if the amount of
     such adjustment shall be less than $.02 per share, but any adjustment that
     would otherwise be then required to be made shall be carried forward and
     shall be made at the time of and together with the next subsequent
     adjustment, which, together with any adjustment so carried forward, shall
     amount to not less than $.02 per share.  If the Company at any time issues
     shares of Common Stock by way of dividend on any class of stock of the
     Company or subdivides or combines the outstanding shares of Common Stock,
     said amount of $.02 per share (as increased or decreased, if the same
     amount shall have been adjusted previously in accordance with the
     provisions of this Section 5) shall be proportionately increased in the
     case of a combination or decreased in the case of a subdivision or stock
     dividend so as to appropriately reflect the same.

     5.2. Adjustment of Shares.  Upon each adjustment of the Purchase Price
          --------------------
pursuant to subdivisions (a) and (b) of Section 5.1 of this Warrant, the number
of shares of Common Stock purchasable upon exercise of this Warrant shall be
adjusted to the number of shares of Common Stock, calculated to the nearest one
hundredth of a share, obtained by multiplying the number of shares of Common
Stock purchasable immediately prior to such adjustment upon the exercise of this
Warrant by a fraction, the numerator of which is the Purchase Price in effect
prior to such adjustment and the denominator of which is the adjusted Purchase
Price.

     5.3. Certification by Company.  Whenever the Purchase Price is adjusted as
          ------------------------
provided in this Section 5, the Company shall compute the adjusted Purchase
Price in accordance with this Section 5 and shall prepare a certificate signed
by its Chief Financial Officer or any other executive officer setting forth the
adjusted Purchase Price, and setting forth in reasonable detail the facts
requiring such adjustment, the information on which such calculation is based,
and the method of such adjustment.  Such certificate shall be delivered to the
Registered Holder.

     5.4. Form of Warrant.  The form of this Warrant need not be changed because
          ---------------
of any change in the Purchase Price pursuant to this Section 5 and any Warrant
issued after such change may state the same Purchase Price and the same number
of shares of Common Stock as are stated in this Warrant as initially issued.

6.   Adjustment for Reorganization, Consolidation, Merger, Etc.

     6.1. Merger, Etc.  If at any time or from time to time after the date of
          -----------
issuance of this Warrant, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company within three (3)
years from the date of such transfer (any such transaction being hereinafter
referred to as a "Reorganization"), then the Registered Holder, upon the
exercise of this Warrant at any time after the consummation or effective date of
such Reorganization, shall receive, in lieu of the shares of Common Stock
issuable on such exercise prior to such consummation or such effective date, the
stock and other securities and property (including cash) to which the Registered
Holder would have been entitled upon such consummation or effective date of such
Reorganization, if the Registered Holder had so exercised this Warrant
immediately prior thereto (all subject to further adjustment thereafter as
provided in Section 5).

     6.2. Dissolution.  Except as otherwise expressly provided in Section 6.1,
          -----------
in the event of any dissolution of the Company following the transfer of all or
substantially all of its properties or assets, the Company, prior to such
dissolution, shall at its expense deliver or cause to be delivered the stock and
other securities and property (including cash, where applicable) receivable by
the Registered Holder after the effective date of such dissolution to a bank or
trust company having its principal office in Denver, Colorado, as trustee for
the Registered Holder.

     6.3. Continuation of Terms.  Except as otherwise expressly provided in
          ---------------------
Section 6.1, upon any reorganization, consolidation, merger or transfer (and any
dissolution following any transfer) referred to in this Section 6, this Warrant
shall continue in full force and effect and the terms hereof shall be applicable
to the shares of stock and other securities and property receivable on the
exercise of this Warrant after the consummation of such reorganization,
consolidation or merger or the effective date of dissolution following any such
transfer, as the case
<PAGE>

may be, and shall be binding upon the issuer of any such stock or other
securities, including, in the case of any such transfer, the person acquiring
all or substantially all of the properties or assets of the Company, whether or
not such person shall have expressly assumed the terms of this Warrant.

7.   No Dilution or Impairment.  The Company will not, by amendment of its
Articles of Incorporation or Bylaws, or through any reorganization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms of this Warrant, but will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such action as may
be necessary or appropriate in order to protect the rights of the Registered
Holder against dilution (to the extent specifically provided in this Warrant) or
other impairment. Without limiting the generality of the foregoing, the Company
(a) will not increase the par value of any shares of stock receivable on the
exercise of the Warrants above the amount payable therefor on such exercise, and
(b) will not effect a subdivision or split up of shares or similar transaction
with respect to any class of the Common Stock without effecting an equivalent
transaction with respect to all other classes of Common Stock.

8.   Representations and Warranties of Record Holder.  By accepting delivery of
this Warrant, the Registered Holder hereby represents and warrants to, and
covenants with, the Company as follows:

          (a) The Registered Holder has been given access to full and complete
     information regarding the Company and has utilized such access to the
     Registered Holder's satisfaction for the purpose of obtaining such
     information regarding the Company as the Registered Holder has reasonably
     requested; and, particularly, the Registered Holder has been given
     reasonable opportunity to ask questions of, and receive answers from,
     representatives of the Company concerning the terms and conditions of the
     offering of the Warrant and the Shares and to obtain any additional
     information, to the extent reasonably available.

          (b) The Registered Holder believes that an investment in the Warrant
     and the Shares is suitable for the Registered Holder based upon the
     Registered Holder's investment objectives and financial needs.  The
     Registered Holder (i) recognizes that the Securities as an investment
     involve a high degree of risk; (ii) has adequate means for providing for
     the Registered Holder's current financial needs and business contingencies;
     (iii) has no need for liquidity in this investment; (iv) at the present
     time, can afford a complete loss of such investment; and (v) does not have
     an overall commitment to investments which are not readily marketable that
     is disproportionate to the Registered Holder's net worth, and the
     Registered Holder's investment in the Warrant and the Shares will not cause
     such overall commitment to become excessive.

          (c) The Registered Holder, in reaching a decision to subscribe, has
     such knowledge and experience in financial and business matters that the
     Registered Holder is capable of reading and interpreting financial
     statements and evaluating the merits and risk of an investment in the
     Warrant and the Shares and has the net worth to undertake such risks.

          (d) The Registered Holder has obtained, to the extent the Registered
     Holder deems necessary, the Registered Holder's own professional advice
     with respect to the risks inherent in the investment in the Warrant and the
     Shares, and the suitability of an investment in the Warrant and the Shares
     in light of the Registered Holder's financial condition and investment
     needs.

          (e) The Registered Holder realizes that (i) the purchase of the
     Warrant and the Shares is a long-term investment; (ii) the purchaser of the
     Warrant and the Shares must bear the economic risk of investment for an
     indefinite period of time because the Warrant and the Shares have not been
     registered under the Act or under the securities laws of any state and,
     therefore, the Warrant and the Shares cannot be resold unless they are
     subsequently registered under said laws or exemptions from such
     registrations are available; and (iii) the transferability of the Warrant
     and the Shares is restricted and (A) requires conformity with the
     restrictions contained in Section 2 of this Warrant and (B) stop transfer
     instructions will be placed with the transfer agent for the Warrant and the
     Shares and a legend will be placed on the certificate(s) representing the
     Warrant and the Shares referring to the applicable restrictions on
     transferability.
<PAGE>

          (f) The Registered Holder has been advised and understands that the
     Warrant and the Shares have not been registered under the Securities Act or
     applicable state securities laws and that the Warrant and the Shares are
     being offered and sold pursuant to exemptions from such laws. The Warrant
     and the Shares are being acquired for the Registered Holder's own account
     and for investment purposes only, and without the intention of reselling or
     redistributing the same, and the Registered Holder has made no agreement
     with others regarding any of the Warrant and the Shares. The Registered
     Holder's financial condition is such that it is not likely that it will be
     necessary to dispose of any of the Warrant or the Shares in the foreseeable
     future. The Registered Holder is aware that, in the view of the Securities
     and Exchange Commission, a purchase of such securities with an intent to
     resell by reason of any foreseeable specific contingency or anticipated
     change in market value, or any change in the condition of the Company, or
     in connection with a contemplated liquidation settlement of any loan
     obtained for the acquisition of such securities and for which such
     securities were pledged, would represent an intent inconsistent with the
     representations set forth above.

          (g) The Registered Holder represents and warrants that the Warrant and
     the Shares are being purchased by the Registered Holder in the Registered
     Holder's name solely for the Registered Holder's own beneficial interest
     and not as nominee for, or on behalf of or for the beneficial interest of,
     or with the intention to transfer to, any other person, trust or
     organization.

9.   Right of Redemption.  This Warrant shall be redeemable, in whole or in
part, at the option of the Company by resolution of its Board of Directors, at
any time and from time to time on or after the date, if any, upon which
Switchboard, Inc. shall have exercised the Perpetual License Option in
accordance with the terms of Section 8 of the Agreement, and prior to any
exercise thereof at a redemption price in cash equal to $.05per Warrant to be
redeemed (the "Redemption Price"). Not less than 30 nor more than 60 days prior
to the date fixed for redemption, a notice (the "Redemption Notice") specifying
the time and place thereof and the Redemption Price per Warrant to be redeemed
shall be given by mail to the Registered Holder at its address as the same shall
appear on the books of the Company. Holder shall have the right to exercise such
Warrant at any time prior to any such redemption. Upon tender of the Redemption
Price in accordance with the Redemption Notice, the Warrants to be redeemed as
indicated in the Redemption Notice shall no longer be deemed to be outstanding
and the Registered Holder shall have no claim against the Company, except the
right to receive the Redemption Price payable upon such redemption, without
interest, upon surrender (and endorsement, if required by the Company) of the
Warrant.

10.  Notice of Record Date.  In case of:

          (a) any taking by the Company of a record of the holders of any class
     of its securities for the purpose of determining the holders thereof who
     are entitled to receive any dividend or other distribution, or any right to
     subscribe for, purchase or otherwise acquire any shares of stock of any
     class or any other securities or property, or to receive any other right,
     or

          (b) any capital reorganization of the Company, any reclassification or
     recapitalization of the capital stock of the Company, any transfer of all
     or substantially all the assets of the Company, any consolidation or merger
     of the Company, or any voluntary or involuntary dissolution, liquidation or
     winding up of the Company, or

          (c) the occurrence of any event resulting in the voluntary or
     involuntary dissolution, liquidation or winding up of the Company,

then the Company will mail or cause to be mailed to each Registered Holder a
notice specifying (i) the date on which any record is to be taken for the
purpose of any such dividend, distribution or right, and stating the amount and
character of such dividend, distribution or right, (ii) the date on which any
such reorganization, reclassification, recapitalization, transfer,
consolidation, merger, dissolution, liquidation or winding up is to take place,
and the time, if any is to be fixed, as of which the holders of record of Common
Stock (or Other Securities) shall be entitled to exchange their Common Stock (or
Other Securities) for securities or other property deliverable on such
reorganization, reclassification, recapitalization, transfer, consolidation,
merger, dissolution, liquidation or winding up, and (iii) the amount and
character of any stock or other securities, or rights or options with respect
thereto, proposed to be issued or granted, the date of such proposed issue or
grant and the persons or class of persons to
<PAGE>

whom such proposed issue or grant is to be offered or made. Such notice shall be
mailed at least 30 days prior to the date specified in such notice on which any
such action is to be taken.

11.  Exchange of Warrants.  On surrender for exchange of any Warrant, properly
endorsed, to the Company, the Company, at its expense, will issue and deliver to
or (subject to Section 2 of this Warrant) on the order of the holder thereof a
new Warrant or Warrants of like tenor, in the name of such holder or as such
holder (on payment by such holder of any applicable transfer taxes) may direct,
calling in the aggregate on the face or faces thereof for the number of shares
of Common Stock called for on the face or faces of the Warrant or Warrants so
surrendered.

12.  Replacement of Warrants.  On receipt of evidence reasonably satisfactory to
the Company of the loss, theft, destruction or mutilation of any Warrant and, in
the case of any such loss, theft or destruction of any Warrant, on delivery of
an indemnity agreement or security reasonably satisfactory in form and amount to
the Company or, in the case of any such mutilation, on surrender and
cancellation of such Warrant, the Company, at its expense, will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

13.  Warrant Agent.  The Company may, by written notice to each holder of a
Warrant, appoint an agent having an office in Denver, Colorado, for the purpose
of issuing shares of Common Stock on the exercise of this Warrant pursuant to
Section 3, exchanging Warrants pursuant to Section 11, and replacing Warrants
pursuant to Section 11, or any of the foregoing, and thereafter any such
issuance, exchange or replacement, as the case may be, shall be made at such
office by such agent.

14.  Remedies.  The Company stipulates that the remedies at law of the holder of
this Warrant in the event of any default or threatened default by the Company in
the performance of or compliance with any of the terms of this Warrant are not
and will not be adequate, and that such terms may be specifically enforced by a
decree for the specific performance of the terms of this Warrant or by an
injunction against a violation of any of the terms of this Warrant.

15.  Negotiability, Etc.  This Warrant is issued upon the following terms, to
all of which each Registered Holder or owner hereof by the taking hereof
consents and agrees:

          (a) subject to the terms of Section 2 of this Warrant, title to this
     Warrant may be transferred by endorsement (by the Registered Holder hereof
     executing the form of Assignment attached hereto as Annex B) and delivery
                                                         -------
     in the same manner as in the case of a negotiable instrument transferable
     by endorsement and delivery;

          (b) any person in possession of this Warrant properly endorsed is
     authorized to represent himself as absolute owner hereof and is empowered
     to transfer absolute title hereto by endorsement and delivery hereof to a
     bona fide purchaser hereof for value; each prior taker or owner waives and
     renounces all of his equities or rights in this Warrant in favor of each
     such bona fide purchaser, and each such bona fide purchaser shall acquire
     absolute title hereto and to all rights represented hereby; and

          (c) until this Warrant is transferred on the books of the Company, the
     Company may treat the Registered Holder hereof as the absolute owner hereof
     for all purposes, notwithstanding any notice to the contrary.

16.  Notices.  All notices and other communications from the Company to the
Registered Holder of this Warrant shall be given in writing (unless otherwise

following deposit of such notice with an internationally recognized courier

furnished to the Company in writing by such Registered Holder or, until any such
Registered Holder furnishes to the Company an address, then to, and at the
address of, the last Registered Holder of this Warrant who has so furnished an
address to the Company.

17.  Miscellaneous.  This Warrant and any term hereof may be changed, waived,
discharged or terminated only by an instrument in writing signed by the party
against which enforcement of such change, waiver, discharge or termination is

                                  AMENDMENT TO
                   DEVELOPMENT, ACCESS AND LICENSE AGREEMENT


     This amendment to the Development, Access and License Agreement (the
"Agreement") entered into as of and effective June 30, 1999, between
Switchboard, Inc., a Delaware corporation ("SB"), and Online System Services,
Inc., a Colorado corporation which plans to change its name to WEBB Interactive
Services, Inc. ("WEBB") (collectively "the Parties") is entered into as of and
effective August ____, 1999.  The Agreement, as amended hereby, determines the
rights and obligations of SB and WEBB with respect to the subject matter of the
Agreement.

     Sections 2.1, 3.3, 7.2, 7.3 and 14.19 of the Agreement are hereby amended
in their entirety to read as follows:

     2.1  "Exclusivity Period" means subject to compliance with the terms and
           ------------------
     conditions of this Agreement, the period from June 30, 1999 through
     September 30, 1999, subject to extensions as provided in Sections 7.3 and
     8.


     3.3  Phase 3.  Providing that SB has elected to extend the Exclusivity
          -------
     Period in accordance with the terms of Section 7.3, commencing on SB's
     acceptance of Phase 2 in accordance with Section 3.4, WEBB will develop a
     further expanded version of the XML Site Generation Platform ("Phase 3"),
     integrating the requirements and specifications to be jointly defined by
     WEBB and SB ("Phase 3 Specifications") which shall incorporate the
     following types of features:

          (a) Vertical templates for thirty (30) additional categories of
     businesses, including clip art and design formats and data intake
     interfaces for each;

          (b) Integration of interactive voice recognition (IVR) services for
     capturing content and design preference information from merchants; and

          (c) Expanded integration capability for third party content into
     Vertical Template Sites.

          (d) Extension and modification of XML site generation platform
     required to deploy and administer multiple outlet dealer networks from
     common templates

     Subject, to the foregoing, WEBB shall complete the Phase 3 deliverables on
     or before December 31, 1999 provided that the Phase 3 Specifications are
     agreed to by the Parties by September 15, 1999. The parties shall use good
     faith efforts to agree to the Phase 3 Specifications by September 15, 1999.
     If they fail to do so, the delivery date for Phase 3 deliverables shall be
     moved back by the number of days equivalent to the number of days between
     September 15, 1999 and the completion of the Phase 3 Specifications. In the
     event that SB requests any reasonable changes to the Phase 3
     Specifications, the completion dates specified above shall be extended a
     reasonable amount of time to allow for implementation of such changes.

     7.2  Site Generation Platform Fee.  During the Term of this Agreement, SB
          -----------------------------
     shall pay WEBB the following Site Generation Platform fees for web site
     generation or modification/maintenance and HTML conversion:
<PAGE>

          (i) $4 per month for each Standard Template Site hosted in such month
     during the first two (2) years of the Term of this Agreement and $3 per
     month thereafter during the Term of this Agreement for each such site; and

          (ii) $5 per month for each Vertical Template Site hosted in such month
     during the first two (2) years of the Term of this Agreement and $3 per
     month thereafter during the Term of this Agreement for each such site.

     In the event that SB does not elect to extend the Exclusivity Period for
     the nine-month period ending June 30, 2000, the monthly payments in (i) and
     (ii) above shall be increased for the balance of the year ending June 30,
     2000, from the $4.00 per month amount for the Standard Template Site to
     $5.00 per month, and for the Vertical Template Site from the $5.00 per
     month amount, to $6.00 per month. The Parties will negotiate in good faith
     to establish the amount of such monthly fees for the remaining Term of this
     Agreement.

     In lieu of the monthly payments set forth above for specific sites, during
     the Term of this Agreement, SB shall pay WEBB the following Site Generation
     Platform Fees for web sites generated by or for SB Customers through the
     XML Site Generation Platform using tools and templates developed
     specifically for national and/or multi-dealer systems pursuant to Phase 3
     Specifications: (i) the greater of $1 per month for which each such
     national or multi-dealer web site is hosted, or (ii) 20% of Net Revenues
     recognized therefrom by SB during any such month.

     SB shall commence payment of Site Generation Platform Fees upon the earlier

3.  Further Agreement.   In consideration of each party's performance as stated
    -----------------
in Section 1 and 2, the parties hereby agree to enter into a written agreement
on mutually agreeable terms no later than July 31, 1999 pursuant to which the

     (a)       WEBB will have a right to display co-branded versions of the

               through links on the WEBB Site.

     (e)  SB shall have the right to sell banner advertisements on pages of the

          inventory made available under this provision that was not
          subsequently used by Webb's third party will revert to SB for its use

          month's inventory. In the event that Webb's third party customer fails
          to claim such inventory for that month SB shall sell the inventory and
          split revenues with Webb based on formulas outlined in this section.

     (f)  SB will host the Switchboard Directory Services.

     (g)  SB agrees to use commercially reasonable efforts to keep the co-
          branded versions of the Switchboard Directory services continually
          available to Webb and Webb's customers on a 24x7 basis, and maintain
          agreed upon levels of infrastructure and operational standards.

     (h)  SB and Webb will agree upon penalty and termination provisions
          associated with Chronic Interruptions of Service.

     (i)  This Agreement will be for a one-year term.

IN WITNESS WHEREOF, the parties, through their authorized representatives, set
their hands and seals as of the Effective Date.
