SUBJECT TO COMPLETION, DATED SEPTEMBER 6, 2001                        PROSPECTUS

                         WEBB INTERACTIVE SERVICES, INC.

         This is a public offering of a maximum of 3,152,658 shares of common
stock of Webb Interactive Services, Inc., including 2,774,950 shares which are
reserved for issuance under convertible preferred stock, convertible promissory
notes and upon the exercise of stock purchase warrants. All of the shares are
being offered for sale by Castle Creek Technology Partners LLC. We will not
receive any of the proceeds from the offer and sale of the common stock.


         The Nasdaq National 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 2 of this prospectus.

         Because Castle Creek Technology Partners LLC 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 Castle Creek
Technology Partners LLC.

         Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of the securities or passed on the
adequacy of the disclosures in this prospectus. Any representation to the
contrary is a criminal offense.


                The date of this prospectus is September __, 2001


                         WEBB INTERACTIVE SERVICES, INC.

         Webb provides online commerce and communication solutions for
businesses. Our AccelX business consists of Internet-based software products and
services designed to assist small businesses in developing, maintaining and
strengthening local buyer-seller relationships. Our Jabber, Inc. subsidiary is
in the early stages of building a business around commercializing open-source
instant messaging products and services for large enterprises and internet
service providers.

         Before January 2000, we were organized around our primary market focus
on local commerce services, with an additional business unit dedicated to
e-banking services. During the third quarter of fiscal 2000, we discontinued our
e-banking business. In February 2000, we formed a new subsidiary to
commercialize separately the Jabber.org instant messaging system from our AccelX
business. We intend to seek participation from external partners to help us
expand our instant messaging business. Under a July 17, 2001 Stock Purchase
Agreement with Jabber and us, France Telecom Technologies Investissements
acquired approximately 15% of Jabber's outstanding capital stock in exchange for
the cancellation of a loan to Jabber of $2,441,000 and the payment to us of
$750,000. France Telecom Technologies Investissements is to purchase additional
shares from Jabber during September 2001 for additional consideration of
$1,750,000, and may acquire additional shares from Jabber in January 2002 for
additional consideration of $2,000,000, depending on Jabber's revenues in
2001.


         We were incorporated under the laws of Colorado on March 22, 1994. Our
executive offices are located at 1899 Wynkoop, Suite 600, Denver, Colorado
80202, telephone number (303) 296-9200.

                                  RISK FACTORS

         Our independent public accountants have indicated that we may not have
sufficient cash to fund future losses from operations. In the report issued by
our independent public accountants accompanying our financial statements for the
year ended December 31, 2000, they indicated there was substantial doubt about
our ability to continue as a going concern. Their report notes that, among other
factors affecting our ability to continue as a going concern, we have incurred
significant and recurring losses from operations and our operations have used
substantial amounts of cash. These losses are expected to continue and we will
require additional capital to fund these operating losses. The availability of
additional capital is uncertain. Our financial statements have been prepared
assuming that we will continue as a going concern and may be of limited utility
to an investor because they do not include any adjustments relating to the
recoverability and classification asset carrying amounts or the amount and
classification of liabilities that might result should we be unable to continue
as a going concern.


         Our limited operating history makes it difficult to evaluate our
business. We were founded in March 1994 and began sales in February 1995.
Subsequently, our business model has changed periodically to reflect changes in
technology and markets. We have a limited operating history for our current
business model upon which you may evaluate us. Our business is subject to the
risks, exposures 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;
         .  Limited ability to adjust our business plan to address marketplace
            and technological changes; and
         .  Difficulty in obtaining operating capital.

         We expect to incur net losses at least through 2002. We have incurred
net losses since we began our business totaling approximately $108 million
through June 30, 2001, including approximately $59.5 million of non-cash
expenses. We expect to incur additional substantial operating and net losses in
2001 and for the next one or more years. We expect to incur these additional
losses because:


         .  We intend to increase our capital expenditures and operating
            expenses by more than $2 million in 2001 to cover the increasing
            activities of  our Jabber, Inc. subsidiary;

                                       2


         .  We acquired goodwill and other intangible assets totaling
            approximately $24 million as a part of the acquisitions of three
            businesses which will be amortized over their estimated useful lives
            of approximately three years; and
         .  We may continue to incur significant non-cash expenses due to
            financing and other equity-based transactions. The current
            competitive business and capital environments likely will result
            in our issuance of similar securities in future financing
            transactions.

         If we are unable to raise additional working capital, we may not be
able to sustain our operations. Because our present cash and cash equivalents,
working capital and commitments for additional equity investments will, based on
current estimates, be adequate to sustain our current level of operations only
until September 2001 for our AccelX business and to February 2002 for our Jabber
business, we will need to obtain additional capital to fund our businesses.
Operating expenses for our AccelX business exceed revenues by more than $250,000
per month, and operating expenses for our Jabber business exceed revenues by
more than $600,000 per month. There is no assurance that we will be able to
raise additional funds in amounts required or upon acceptable terms. If we
cannot raise additional funds when needed, we may be required to curtail or
scale back our operations or sell some of our assets.





         We may not earn revenues sufficient to remain in business. Our ability
to become profitable depends on whether we can sell our products and services
for more than it cost to produce and support them. Our future sales also need to
provide sufficient margin to support our ongoing operating activities. 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
            services.

         Because of the new and evolving nature of the Internet and our limited
operating history, 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 charge, or whether current or future pricing levels will be
sustainable.

         If the Internet does not develop into a significant source of
business-related communication, then our business will not be successful. Our
business plan assumes that the Internet will develop into a significant source
of business-related 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, may not be successful. 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.

         We are dependent upon our suppliers to maintain good relationships with
the users of our products and services. 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 obtain or use them through
our distribution partners. Our distribution partners, and not us, will
substantially control the customer relationship with these users. If the
relationship between our distribution partners and the users of our products and
services suffers, we may experience a loss of the users of our products and
services as they seek relationships with other distributors.

         We must continually develop new products which appeal to our customers.
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.

                                       3


         Even if we are able to identify new opportunities, our working capital
constraints limit our ability to pursue them. If we are unable to identify and
develop and introduce new products and services on a timely basis, demand for
our products and services will decline.

         We must identify and develop markets for our products and services. A
suitable market for our products and services may not develop or, if it does
develop, it may take years for the market to become large enough to support
significant business opportunities. Even if we are able to successfully
identify, develop, and introduce new products and services there is no assurance
that a suitable market for these products and services will materialize. The
following factors could affect the success of our products and services and our
ability to address sustainable markets:

         .  The failure of our business plan to accurately predict the types of
            products and services the future Internet marketplace will demand;
         .  Our limited working capital may not allow us to commit the resources
            required to adequately support the introduction of new products and
            services.
         .  The failure of our business plan to accurately predict the estimated
            sales cycle, price and acceptance of our products and services; or
         .  The development by others of products and services that makes our
            products and services noncompetitive or obsolete.

         There is a lot of competition in the Internet market which could hurt
our revenues or cause our expenses to increase. Our current and prospective
competitors include many companies whose financial, technical, marketing and
other resources are substantially greater than ours. We may not have the
financial resources, technical expertise or marketing, sales and support
capabilities to compete successfully. The presence of these competitors in the
Internet marketplace could hurt our business by causing us to:

         .  Reduce the average selling price of our products and services; or
         .  Increase our spending on marketing, sales and product development.

         We may not be able to offset the effects of price reductions or
increases in spending. Further, our financial condition may put us at a
competitive disadvantage relative to our competitors.

         We have a limited number of customers, so the loss of one or more of
them will substantially hurt our revenues. We had three customers representing
66% of revenues for the year ended December 31, 2000, and five customers
representing 87% of revenues for the six months ended June 30, 2001. We may not
be able to attract or retain major customers.


         It usually takes a long time and significant expense before we are able
to make a sale of our products and services to a customer. While our sales cycle
varies from customer to customer, it is long, typically ranging from two to nine
months or more, and unpredictable. 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 about the use and benefits of our
Internet technologies and services. 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. To respond to, or anticipate, customer
requirements, we may begin development work before having a signed contract,
which exposes us to the risk that the development work will not be recovered
from revenue from that customer.

         It will take at least one or more years before we earn significant
revenues from our products and services. Many of our products and services,
particularly our AccelX products and services, are offered on a revenue-share
basis. Once we have sold our products and services, it may take three or more
months for them to be integrated into our customers' businesses and product
offerings. Further, even after our customers have begun to market our products
and services to their customers, our limited operating history does not enable
us to predict how long it will take before their customers will begin to use our
products and services in sufficient quantity to provide us with significant
recurring revenues. Even if significant business for our products and services
does develop, we may not recognize meaningful revenues from this business for
many months or possibly even for one or more years. This

                                       4


could require that we raise significant additional investment capital to sustain
our operations and could effect on our ability to become profitable within the
next one or more years.

         Offering proprietary products based on the Jabber.org open-source
movement may jeopardize our relationship with open-source communities. An
important element of the business model for our Jabber, Inc. subsidiary is based
upon Jabber's ability to offer proprietary products compatible with Jabber.org
open-source instant messaging systems. A key element of open-source software
development movements is that the software and its code be offered to other
developers and users free, provided that anyone who makes an improvement or
modification to the software and who intends to commercialize the improvement or
modification, makes them available for free to the community and other users. If
the Jabber.org open-source community or other open-source communities withdraw
their support for either Jabber, Inc. or Jabber instant messaging products,
demand for Jabber instant messaging products will likely decline.

         We may be unable to reduce our expenses if sales do not occur as
expected. Because 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. Our expense levels are based in part on our expectations of
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. 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 result in operating losses or reduced profitability.
Further, we intend to increase our capital expenditures and operating expenses
to fund the operations of our Jabber, Inc. subsidiary. If these expenditures are
not subsequently followed by increased sales with substantial margin, then we
will need to raise additional capital to stay in business.

         An investment in our common stock is risky because the price of our
stock is highly volatile. Our common stock closed as high as $6.25 per share and
as low as $1.00 per share between January 1, 2001 and August 7, 2001.
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;
         .  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.

         We have issued numerous options, warrants, and convertible securities
to acquire our common stock that could have a dilutive effect on our
shareholders. As of August 7, 2001, we had issued warrants and options to
acquire approximately 4,990,103 shares of our common stock, exercisable at
prices ranging from $1.00 to $58.25 per share, with a weighted average exercise
price of approximately $7.84 per share. We had also reserved 1,952,959 shares of
common stock for issuance upon conversion of our 10% convertible notes and
series B-2 and C-1 convertible preferred stock. During the terms of these
derivative securities, the holders 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 applicable
exercise or conversion price. The increase in the outstanding shares of our
common stock because of the exercise or conversion of these derivative
securities could result in a significant decrease in the percentage ownership of
our common stock by current and future holders of our common stock.


         The significant number of shares issuable upon conversion of our
convertible securities could make it difficult to obtain additional financing.
1,952,959 shares of our common stock may be issued if our 10% notes and series
B-2 and C-1 convertible preferred stock are converted. This number could
increase due to future financings. Due to this significant potential increase in
the number of our outstanding shares of common stock, new investors may either
decline to make an investment in Webb due to the potential negative effect this
additional dilution could have on their investment or require that their
investment be on terms at least as favorable as the terms of the notes or
convertible preferred stock. If we are required to provide similar terms to
obtain required financing in the future, the


                                       5



onerous terms and significant dilution of these financings could be perpetuated
and significantly increased. In addition, the current price of our common stock
may make it difficult to raise capital as a result of the terms of the notes and
the convertible preferred stock, because issuances of common stock below prices
specified in the notes and the convertible preferred stock would result in
substantial additional shares being issued to holders of these securities, and
substantial dilution to other shareholders.


         Future sales of our common stock in the public market could depress the
price of our common stock. Actual or potential future sales of substantial
amounts of common stock in the public market could depress 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 7, 2001,
these shares consist of:


         .  Up to 1,952,959 shares issuable upon conversion of the 10%
            convertible notes and series B-2 and C-1 preferred stock; and


         .  Approximately 4,999,000 shares issuable to warrant and option
            holders.


         Future sales of our common stock in the public market could limit our
ability to raise capital. Actual or potential future sales of substantial
amounts of our common stock in the public by our officers and directors, upon
exercise or conversion of derivative securities could affect our ability to
raise capital through the sale of equity securities.

         The trading volume of our common stock may diminish significantly if
our common stock is delisted from the Nasdaq National Market. Although our
shares are traded on the Nasdaq National Market, there is no assurance that they
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
transactions in low-priced 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, making it more difficult for
purchasers of our common stock to dispose of their shares.

         The issuance of convertible securities has resulted in significant
non-cash expenses which has increased significantly our net loss applicable to
common shareholders. We recorded a non-cash expense of approximately $2.5
million as additional interest expense for the six months ended June 30, 2001
due to the issuance of our 10% convertible notes in 1999. We also recorded a
$2.9 million non-cash expense for the six months ended June 30, 2001 for
preferred dividends due to the terms of our series C-1 issued during the first
quarter of 2001 and B-2 preferred stock issued during the first quarter of 2000.
We may incur significant additional non-cash expenses due to future
financings.


                        PARENT-ONLY FINANCIAL INFORMATION


         The stock purchase agreement under which France Telecom Technologies
Investissements made on investment on our Jabber, Inc. subsidiary requires that
these investment proceeds be used only by Jabber and that they may not be used
to fund any of our business activities. As a result of sales of Jabber
securities by us or Jabber, we may lose the ability to consolidate the financial
statements of Jabber for accounting purposes. As a result, we believe that
financial information for Webb on a stand-alone basis could be beneficial to an
investor's understanding of Webb. Information regarding the separate segments of
our Jabber and Accel X business are provided in our periodic reports of Form 10-
KSB and 10-QSB filed with the Securities and Exchange Commission.

                                USE OF PROCEEDS

         Castle Creek Technology Partners LLC is offering all of the shares to
be sold. We will not receive any of the proceeds from the offer and sale of the
shares of common stock. However, 821,991 of the shares offered by Castle Creek
Technology Partners LLC are issuable upon the exercise of outstanding stock
purchase warrants at exercise prices ranging from $3.75 to $9.3343 per share. If
these warrants were exercised in full, we would receive gross proceeds of
$3,921,402.

                              SELLING SHAREHOLDER

         The common stock covered by this prospectus consists of:

         .  180,082 shares issued upon the conversion of our series B-2
            convertible preferred stock;
         .  1,000,000 shares issuable upon the conversion of our series C-1
            convertible preferred stock;

         .  772,877 shares issuable upon the conversion of our 10% convertible
            promissory notes due August 25, 2002, in the principal amount of
            $1,932,193;

         .  821,991 shares issuable upon the exercise of various stock purchase
            warrants; and
         .  377,708 shares of common stock held by Castle Creek Technology
            Partners LLC.

         Castle Creek Technology Partners LLC acquired its series B-2
convertible preferred stock on September 14, 2000 in exchange for all of its
series B convertible preferred stock. Castle Creek Technology Partners LLC
purchased the series B convertible preferred stock from us, and a warrant to
purchase 171,875 shares of common stock, for $6,250,000 on February 18, 2000.
Castle Creek Technology Partners LLC acquired the series C-1 convertible
preferred stock on February 28, 2001, and a warrant to purchase up to 500,000
shares of common stock, in exchange for a cash investment of $2,500,000. Castle
Creek Technology Partners LLC acquired the 10% convertible promissory notes
during 1999. Castle Creek Technology Partners LLC received a warrant to purchase
136,519 shares of our common stock on December 18, 1999 as part of an amendment
of the terms of the promissory notes, and this warrant was adjusted by its own
terms in February 2001 resulting in an additional 13,597 shares being covered by
the warrant. Castle Creek Technology Partners LLC acquired the 377,708 shares of
common stock when it converted a portion of the series B-2 convertible preferred
stock that it acquired in 2000.


         The number of shares that actually may be sold will be determined by
Castle Creek Technology Partners LLC. Because Castle Creek Technology Partners
LLC may sell all, some or none of the shares of common stock which it holds, and
because this offering is not being underwritten, no estimate can be given of the
number of shares of common stock that will be held by Castle Creek Technology
Partners LLC upon termination of the offering.

         The following table provides information as of August 7, 2001, about
Castle Creek Technology Partners LLC, including:


         .  Its beneficial ownership of common stock; and
         .  The maximum number of shares of common stock offered.

The information presented is based on data furnished to us by Castle Creek
Technology Partners LLC.

         Under the registration rights agreement, we are required to register
for resale by Castle Creek Technology Partners LLC 3,152,658 shares of our
common stock. This amount is based upon the number of shares:


         .  Issuable upon the conversion of our series B-2 and C-1 convertible
            preferred stock;

         .  Issuable upon the conversion of our 10% convertible promissory
            notes;

         .  Issuable upon the exercise of various stock purchase warrants; and
         .  Held by Castle Creek Technology Partners LLC.

159,010 of these shares are subject to an effective registration statement filed
with the Securities and Exchange Commission in February 2000. These shares are
being offered by this prospectus.


         Under the terms of the convertible preferred stock, the convertible
promissory notes and the warrants, each is convertible or exercisable by Castle
Creek Technology Partners LLC up to that number of shares, including the number
of shares of common stock owned by Castle Creek Technology Partners LLC, that
would not exceed 4.99% of the then outstanding shares of our common stock as
determined under section 13(d) of the Securities Exchange Act of 1934. This
limit does not include unconverted or unexercised shares under the convertible
preferred stock, convertible promissory notes or the warrants. Because of this
limitation, the number of shares of common stock contained in the third and
fourth columns in the table below for Castle Creek Technology Partners LLC
exceeds the number of shares of common stock that Castle Creek Technology
Partners LLC beneficially owns under section 13(d) as of August 7, 2001. This
4.99% limit may not prevent Castle Creek Technology Partners LLC from converting
all of its convertible preferred stock or the convertible promissory notes, or
exercising its warrants, because Castle Creek Technology Partners LLC can
convert the convertible preferred stock or the convertible promissory notes, or
exercise the warrants into 4.99% of our outstanding common stock, then sell all
of that stock to permit it to engage in further conversions or exercises. The
4.99% limit does not prevent Castle Creek Technology Partners LLC from selling
more than 4.99% of our common stock.

include purchases to cover short positions by Castle Creek Technology Partners

position at a lender's request and purchases by the lender in the market of
shares to cover such a short position may constitute an inducement to buy those
shares prohibited by Regulation M. This may affect the marketability of the
common stock.

         As of August 7, 2001, we had 10,873,567 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


                                       13



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, and 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, and 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.

         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 before the payment of distributions to holders
of our common stock.

Series B-2 Convertible Preferred Stock

         As of August 7, 2001, we had 450.205 shares of series B-2 convertible
preferred stock outstanding. On February 18, 2000, we issued 6,250 shares of our
series B convertible preferred stock and a warrant to acquire 171,875 shares of
our common stock to Castle Creek Technology Partners LLC for a cash investment
of $6,250,000. A similar number of series B-2 preferred stock and warrant was
issued to another investor, resulting in the issuance of an aggregate of 12,500
shares of this preferred stock. On September 14, 2000, we agreed to exchange all
of the series B convertible preferred stock for 12,500 shares of series B-2
convertible preferred stock. During December 2000, all but 978 shares of the
series B-2 convertible preferred stock were converted at a conversion price of
$10.20408 per share into an aggregate of 11,522,000 shares of our common stock.
In 2001, an additional 527.795 shares of the series B convertible preferred
stock were converted at a conversion price of $2.50 per share into an aggregate
of 527,795 shares of our common stock. The series B-2 convertible preferred
stock does not bear dividends and does not entitle the holders to any voting
rights except as required by Colorado law. The following is a summary of the
material terms of the series B-2 convertible preferred stock.


         Conversion. The preferred stock is convertible into common stock unless
the conversion would result in the holder being a beneficial owner of more than
4.99% of our common stock. The current conversion price is $2.50 per share.


         The conversion price is also subject to anti-dilution protection if we
issue our common stock at prices less than the conversion price for the
preferred stock or the then current price for our common stock and for stock
splits, stock dividends and other similar transactions. If the conversion price
is reduced, we may be required to record a charge to income.

                                       14


         Redemption.  The holder of the preferred stock has the right to require
us to redeem its shares of preferred stock if we:

         .  do not have a sufficient number of shares of our common stock
            available for the conversion of the preferred stock for any reason;
         .  fail in any material respect to comply with the terms of the
            preferred stock or the purchase agreement under which the preferred
            stock was sold; or
         .  our common stock ceases to be quoted on the Nasdaq Stock Market
            because of any willful action or failure on our part.

The redemption price would be equal to the greater of $1,250 per share of
preferred stock or the market value of the preferred stock based on the then
market value for our common stock.

         Liquidation Preference. If we liquidate, dissolve or wind-up our
business, whether voluntarily or involuntarily, after we pay our debts and other
liabilities, the holder of the preferred stock will be entitled to receive from
our remaining net assets, before any distribution to the holders of our common
stock, the amount of $1,000 per share.

Series C-1 Convertible Preferred Stock

         On February 28, 2001, we issued 2,500 shares of our series C-1
convertible preferred stock and warrants to acquire 500,000 shares of our common
stock to Castle Creek Technology Partners LLC for a cash investment of
$2,500,000. The conversion price for the series C-1 convertible preferred stock
is $2.50 The series C-1 convertible preferred stock does not bear dividends and
does not entitle the holder to any voting rights except as required by Colorado
law.

         The following is a summary of the material terms of the series C-1
convertible preferred stock.

         Conversion. The preferred stock is convertible into common stock unless
the conversion would result in the holder being a beneficial owner of more than
4.99% of our common stock. The current conversion price is $2.50 per share.

issue our common stock at prices less than the conversion price for the
preferred stock or the then current price for our common stock and for stock
splits, stock dividends and other similar transactions. If the conversion price
is reduced, we may be required to record a charge to income.

         Redemption.  The holder of the preferred stock has the right to require
us to redeem its shares of preferred stock if we:

         .  do not have a sufficient number of shares of our common stock
            available for the conversion of the preferred stock for any reason;
         .  fail in any material respect to comply with the terms of the
            preferred stock or the purchase agreement under which the preferred
            stock was sold; or
         .  our common stock ceases to be quoted on the Nasdaq Stock Market
            because of any willful action or failure on our part.

The redemption price would be equal to the greater of $1,250 per share of
preferred stock or the market value of the preferred stock based on the then
market value for our common stock.

         Liquidation Preference. If we liquidate, dissolve or wind-up our
business, whether voluntarily or involuntarily, after we pay our debts and other
liabilities, the holder of the preferred stock will be entitled to receive from
our remaining net assets, before any distribution to the holders of our common
stock, the amount of $1,000 per share.

                                       15


         Registration Rights. The agreement under which the series C-1 preferred
stock was issued requires us to file with the Securities and Exchange Commission
a registration statement for the resale of the shares issuable upon conversion
of this preferred stock and the other shares of common stock being offered for
sale by Castle Creek Technology Partners LLC under this prospectus. The
agreement under which the series C-1 preferred stock was issued also requires us
to use our best efforts to keep the registration statement effective until all
of the registered shares have been resold or can be sold immediately without
compliance with the registration requirements of the Securities Act of 1933
under Rule 144.

         Series C-2 Preferred Convertible Stock. The February 28, 2001 agreement
under which we issued the series C-1 convertible preferred stock and the
accompanying warrant to Castle Creek Technology Partners LLC requires Castle
Creek Technology Partners LLC to purchase, and us to sell, up to 2,500 shares of
series C-2 convertible preferred stock and an accompanying series C-2 warrant
representing the right to purchase additional shares of common stock equal to
20% of the shares issuable upon the conversion of the series C-2 preferred stock
if:

            declared effective by the Securities and Exchange Commission and has
            been effective for 15 days;
         .  Our common stock continues to be listed on the Nasdaq National
            Market;

         .  Our average market capitalization for the three trading days
            immediately preceding the closing of the sale of these securities is
            at least $32,300,000, adjusted for any increase or decrease in the
            number of our outstanding shares of common stock;

         .  Our representations and warranties in the February 28, 2001
            agreement with Castle Creek Technology Partners LLC are true and
            correct in all material respects at the time of the closing; and
         .  There has been no material adverse change in our business, financial
            condition, properties, prospects or results of operations.

         The purchase price of the series C-2 convertible preferred stock and
accompanying warrant is $2,500,000. The series C-2 shares are convertible into
common stock at a price equal to the least of:

         .  80% of the average market price for our common stock for the three
            trading days immediately preceding the issuance of the stock;
         .  80% of the closing bid price for the common stock on the day
            immediately preceding the issuance of the preferred stock; and
         .  $7.50.

         At the time the series C-2 convertible preferred stock is issued, the
maximum number of shares of common stock issuable upon conversion of this
preferred stock will be 1,000,000 shares, and a maximum of 200,000 shares will
be issuable upon exercise of the accompanying warrant.

         The series C-2 convertible preferred stock will not bear dividends and
will not entitle the holder to any voting rights except as required by Colorado
law. The following is a summary of the material terms of the series C-1
convertible preferred stock.

         .  Conversion. The preferred stock is convertible into common stock
            unless the conversion would result in the selling shareholder being
            a beneficial owner of more than 4.99% of our common stock. The
            conversion price is subject to the formula described in the
            preceding paragraph.


            The conversion price is also subject to anti-dilution protection
            if we issue our common stock at prices less than the conversion
            price for the preferred stock or the then current price for our
            common stock and for stock splits, stock dividends and other similar
            transactions. If the conversion price is reduced, we may be required
            to record a charge to income.


         .  Redemption. The holder of the preferred stock has the right to
            require us to redeem its shares of preferred stock if we:


                                       16



         .  do not have a sufficient number of shares of our common stock
            available for the conversion of the preferred stock for any
            reason;


         .  fail in any material respect to comply with the terms of the
            preferred stock or the purchase agreement under which the preferred
            stock was sold; or


         .  our common stock ceases to be quoted on the Nasdaq Stock Market
            because of any willful action or failure on our part.


The redemption price would be equal to the greater of $1,250 per share of
preferred stock or the market value of the preferred stock based on the then
market value for our common stock.


         .  Liquidation Preference. If we liquidate, dissolve or wind-up our
            business, whether voluntary or otherwise, after we pay our debts and
            other liabilities, the holder of the preferred stock will be
            entitled to receive from our remaining net assets, before any
            distribution to the holders of our common stock, the amount of
            $1,000 per share.

We were required under the February 28, 2001 agreement with Castle Creek
Technology Partners LLC to register the maximum number of shares of common stock
issuable upon the conversion of the series C-2 convertible preferred stock and
the exercise of the accompanying warrant as a condition of Castle Creek
Technology Partners LLC's obligation to purchase the series C-2 securities.
Based on the position of the Staff of the Securities and Exchange Commission
that the shares of common stock issuable upon conversion of the series C-2
preferred stock and exercise of the series C-2 warrant could not be included in
the registration statement which includes this prospectus until the series C-2
securities had been issued, these shares of common stock are not part of this
prospectus. This agreement had been amended to eliminate this condition to
Castle Creek Technology Partners LLC's obligation to purchase these series C-2
securities. We have agreed to register with the Securities and Exchange
Commission the shares of common stock issuable upon the conversion and exercise
of the series C-2 securities after the series C-2 securities have been
issued.


10% Convertible Promissory Notes

         On August 25, 1999, we issued to Castle Creek Technology Partners LLC a
three-year 10% convertible promissory note in the amount of $5,000,000. On
December 18, 1999, the terms of the promissory note were amended and we issued
to Castle Creek Technology Partners LLC a warrant to purchase 136,519 shares of
common stock, and this warrant was adjusted by its own terms in February 2001
resulting in an additional 13,597 shares being covered by the warrant. On
February 18, 2000, one-half of the principal amount of the note was converted
into 248,262 shares of common stock at a conversion price of $10.07 per share.
During 2000, an aggregate of $164,110 principal amount of similar 10%
convertible notes were issued to pay interest on the note. In July 2001, Castle
Creek converted a portion of the 10% convertible notes into 42,652 shares of our
common stock. As of August 7, 2001, we had a total of $1,932,193 principal
amount of the 10% convertible notes outstanding. For the period from July 1,
2001 through the maturity date of the notes, August 25, 2002, additional
interest will accrue in the amount of $227,207 assuming the interest is paid in
additional notes. If paid in cash, the interest will be lower due to the absence
of compounding. Upon the issuance of additional convertible promissory notes to
pay this interest, an additional 90,833 shares of common stock would be issuable
upon conversion of the notes. We are required under the February 28, 2001
agreement with Castle Creek Technologies Partners LLC to register any shares of
common stock that are issued upon conversion of these notes. The following is a
summary of the material terms of the promissory notes.


         Conversion Price.  The convertible promissory notes are convertible
into shares of common stock at a conversion price of $2.50 per share.

         Redemption. We can prepay the promissory notes at any time, if the
closing bid price for our common stock for 20 consecutive trading days is at
least 200% of the conversion price then in effect. The redemption price would
equal 115% of the face amount of the convertible notes, plus accrued and unpaid
interest.

                                       17


         Interest. The promissory notes bear interest at an annual rate of 10%.
The holder has the option to elect to receive interest payments in the form of
cash, common stock or a promissory note. If the market value of our common stock
is above $2.50, the issuance of notes to pay interest would result in an
effective interest rate of more than 10%.

Warrant Issued with Series B Convertible Preferred Stock

         Castle Creek Technology Partners LLC owns a five-year warrant to
purchase 171,875 shares of our common stock, which was issued on February 18,
2000. A similar warrant was issued to a second investor as part of its purchase
of series B convertible preferred stock. The exercise price for the warrants is
currently $3.75374 per share. During the first three years of the warrant, the
exercise price is subject to adjustment at the end of each ninety-day period
following the issuance of the warrants. During this period, the exercise price
at the end of each ninety-day period will be adjusted if the market price for
our common stock is less than the exercise price for the warrants, so that the
exercise price will equal the market price for our common stock. The exercise
price for the warrant is also subject to anti-dilution protection if we issue
our common stock at prices less than the exercise price for the warrants and for
stock splits, stock dividends and other similar transactions. If the warrant
price is reset, we may record additional charges to income. The warrants may be
subject to early expiration after an underwritten public offering or one year if
the market price for our common stock exceeds $40.81.

Warrant Issued with Series C-1 Convertible Preferred Stock

         Castle Creek Technology Partners LLC received a three-year warrant to
purchase up to 500,000 shares of our common stock, which was issued on February
28, 2001. The exercise price for the warrant is $3.75 per share. The warrant may
be subject to early expiration after 180 days if the market price for our common
stock exceeds $7.50 for 10 consecutive trading days. The exercise price for the
warrant is subject to anti-dilution protection for stock splits, stock dividends
and other similar transactions

Warrant Issued with Convertible Notes

         In December 1999 we issued Castle Creek Technology Partners LLC a
five-year warrant to purchase 136,519 shares of our common stock as part of an
amendment of the terms of the 10% convertible promissory notes, and this warrant
was adjusted by its own terms in February 2001 resulting in an additional 13,597
shares being covered by the warrant. The exercise price for the warrant is
$9.33431 per share. The warrant is subject to anti-dilution protection if we
issue our common stock at prices less than the exercise prices for the warrant
or the then current price for our common stock and for stock splits, stock
dividends and other similar transactions.

         Our articles of incorporation provide that we shall indemnify, to the
full extent permitted by Colorado law, our directors, officers, employees or
agents who are made, or threatened to be made, a party to a proceeding against
judgments, penalties, fines, settlements and reasonable expenses 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
unenforceable.

                                       19


         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 us or our shareholders;

            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

            benefit.

Item 15. Indemnification of Directors and Officers

     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 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 Webb
against judgments, penalties, fines, settlements and reasonable expenses
incurred by the person in connection with the proceeding if the person conducted
himself or herself in good faith and in a manner he or she reasonably believed
to be in or not opposed to our best interests, and, with respect to any criminal
action or proceeding, had no reasonable cause to believe his or her conduct was
unlawful. Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the "Act") may be permitted to our directors, officers
and controlling persons pursuant to the foregoing provisions, we 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.

     Our articles of incorporation limit the liability of our directors to the
fullest extent permitted by Colorado law. Specifically, the 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 us or our 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 statutory or contractual restrictions; or
     .  any transaction from which the director derives an improper personal
        benefit.

Liability under federal securities law is not limited by the articles of
incorporation.

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:

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

                (ii)  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 in the aggregate, represent a fundamental
                      change in the information in the registration statement.
                      Notwithstanding the foregoing, any increase or decrease in
                      volume of securities offered (if the total dollar value of
                      securities offered would not exceed that which was
                      registered) and any deviation from the low or high end of
                      the estimated maximum offering range may be reflected in
                      the form of prospectus filed with the Commission pursuant
                      to Rule


                      424(b) if, in the aggregate, the changes in volume
                      and price represent no more than a 20 percent change in
                      the maximum aggregate offering price set forth in the
                      "Calculation of Registration Fee" table in the effective
                      registration statement;

                (iii) To include any material information with respect to the
                      plan of distribution not previously disclosed in the
                      registration statement or any material change to such
                      information in the registration statement;

          (2)   That, for the purpose of determining liability under the
                Securities Act of 1933, each such post-effective amendment shall
                be deemed 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.

          (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.


                                  SIGNATURES


     Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this amendment to the
registration statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the city of Denver, State of Colorado, on September 6, 2001.
