               The date of this prospectus is November __, 2001


                        WEBB INTERACTIVE SERVICES, INC.

     Webb is the founder and the majority stockholder of Jabber, Inc., a company
in the early stages of building a business around commercializing open-source
instant messaging software products and services. We formed Jabber, Inc. in
February 2000 to commercialize the Jabber.org instant messaging system begun in
1998 by Jeremy Miller, the founder of this open-source movement. We became the
commercial sponsor of the Jabber.org open-source movement in September 1999 when
Mr. Miller began his employment with us.

     Before October 16, 2001, we were also engaged in developing software
products and services designed to assist small businesses in developing,
maintaining and strengthening local buyer-seller relationships. This business
was terminated on October 16, 2001 as we were unable to obtain financing for
this business on acceptable terms and market conditions for these products and
services were continuing to develop at a slower rate than we had
anticipated.


     Our business plan for Jabber, Inc. includes developing strategic
relationships with companies who have a long-term interest in the development of
products and services utilizing instant messaging. Under a July 17, 2001 stock
purchase agreement with Jabber and us, France Telecom Technologies
Investissements has acquired approximately 22% of Jabber for an investment of $5
million and may acquire another 7% of Jabber for an additional $2 million. On
October 31, 2001, we owned approximately 71% of Jabber.

     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.

                              RECENT DEVELOPMENTS

     On October 16, 2001, we terminated our AccelX local commerce business,
granted a license for software used in this business to Nextron Communications,
Inc. for a license fee of $1 million and sold assets used in this business to
Nextron Communications for an initial purchase price of $500,000. If Nextron
Communications completes a financing for at least $2 million by January 31,
2002, it will pay us an additional $750,000 for these assets. If the financing
transaction is not completed by January 31, 2002, but is completed by June 30,
2002, then Nextron Communications will pay us an additional $350,000 for the
assets. If the financing transaction is not completed by June 30, 2002, then we
will not receive any additional consideration for the assets. We have recorded a
loss of $1,020,000 because of the sale and termination of the AccelX business,
primarily due to non-cash expenses for impairment losses for goodwill and
intangible assets resulting from the acquisition of Update Systems, Inc. in
2000. Any additional consideration will be recorded when payment is assured.

     We reduced the number of our employees by 16 in connection with the
termination of the AccelX business. Thirteen of these employees, including Perry
Evans, our chief executive officer and a director, and Susan Dalton, vice
president of AccelX operations, were hired by Nextron Communications. Mr. Evans
resigned as our chief executive officer, president and as a director, but
continues to serve as a director of our Jabber, Inc. subsidiary. Nextron
Communications has agreed to sublease for up to one year approximately 3,500
square feet in our corporate offices in Denver, Colorado for approximately
$10,000 per month. At October 31, 2001, we employed 48 persons, including nine
administrative and support personnel employed by Webb and 39 persons employed by
Jabber, Inc.

                                 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

                                       2


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 early-stage 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 into 2003. We have incurred net losses since
we began our business totaling approximately $113.1 million through September
30, 2001, including approximately $59.7 million of non-cash expenses. We expect
to incur additional substantial operating and net losses in 2001 and 2002, and
do not expect to achieve positive cash flow from operations until at least 2003.
We expect to incur these additional losses because:

     .    We intend to incur capital expenditures and operating expenses in
          excess of revenues of more than $2 million during the fourth quarter
          of 2001 and the year 2002 to cover the increasing activities of
          Jabber, Inc.;

     .    We expect to spend more than $1.5 million during the fourth quarter of
          2001 and the year 2002 to finance operating expenses besides those for
          Jabber, Inc.; 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 operations for Jabber, Inc. only until
February 2002 and for our other operations until January 2002, we will need to
obtain additional capital to fund our business. Operating expenses for Jabber,
Inc. currently exceed revenues by approximately $300,000 per month. Operating
expenses for our corporate activities, to be funded separately from those for
Jabber, Inc., are expected to be approximately $1 million per year and we have
outstanding payables of approximately $800,000 and a convertible note payable
for approximately $2 million due in August 2002, which are also to be funded
separately from Jabber, Inc. 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 costs 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 extent to which consumers and businesses use our products and
          services; and
     .    The success of our distribution partners in marketing their products
          and services.

     Because of the new and evolving nature of the Internet, the early stage of
our Jabber products 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

                                       3


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.

     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.

     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, including Microsoft, Inc. and AOL Time
Warner, Inc., 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.

     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 six
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.

     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

                                       4


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 incur significant 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 $0.50 per share between January 1, 2001 and October 31, 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; 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.

     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 October 31, 2001, we had issued warrants and options to acquire
approximately 5,429,410 shares of our common stock, exercisable at prices
ranging from $0.65 to $58.25 per share, with a weighted average exercise price
of approximately $4.46 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 onerous terms and significant
dilution of these financings could be perpetuated and significantly increased.
The current price of our common stock may make it difficult to raise capital
because of the terms of the notes and the convertible preferred stock. 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, causing substantial dilution to other shareholders.
For example, if we were required to raise operating capital at current market
prices for our common stock, the number of shares issuable upon conversion of
these securities could increase to more than 6,000,000 shares.


                                       5


     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 October 31,
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 5,429,410 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, and
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. At October 31, 2001, we failed to meet
either the tangible net worth or minimum stock price requirements for continued
listing on the Nasdaq stock market system. On November 13, 2001, we received a
determination from Nasdaq that we are subject to delisting. We have filed a
notice of appeal of this determination. A hearing before the Nasdaq Listing
Qualifications Panel to consider our appeal is scheduled for on January 10,
2002. 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 $2.9 million as
additional interest expense for the nine months ended September 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 nine months ended September 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 an investment in 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 other business activities. We believe that financial
information for Webb on a stand-alone basis could be beneficial to an investor's
understanding of Webb. Based on Jabber's capital structure, corporate governance
structure and Webb's voting rights, Webb has concluded that it controls Jabber
and has consolidated it in the accompanying financial statements.

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 October 31, 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 2,775,230 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

                                       11


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 October 31,
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.

agreement requires us to register the underlying shares of our common stock
under applicable federal and state securities laws, and the other shares of
common stock being offered in this prospectus.  The registration agreement
provides for cross-indemnification of Castle Creek Technology Partners LLC and

liability for the offer and sale of the common stock, including liabilities
under the Securities Act of 1933, and to contribute to payments the parties may
be required to make.  We have agreed to indemnify and hold harmless Castle Creek

include purchases to cover short positions by Castle Creek Technology Partners
LLC, and the failure by Castle Creek Technology Partners LLC to cover a short
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.

Castle Creek Technology Partners LLC will pay any applicable underwriting
commissions and expenses, brokerage fees and transfer taxes, and the fees and
disbursements of its counsel and experts.

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 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 does not bear dividends and does not entitle the
holders to any voting rights except as required by Colorado law. The following

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.

     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.

          the preferred stock or the then current price for our common stock and
          for stock splits, stock dividends and other similar transactions. If

            distribution to the holders of our common stock, the amount of

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.

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 has been amended to eliminate this condition to
Castle Creek Technology Partners


                                       17



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

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.

     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

                                       18


$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.

     We have incorporated by reference in this prospectus our audited financial

                                INDEMNIFICATION

     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.

     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;
     .    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 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 November 29,
2001.
