EXHIBIT 10.18



April 20, 2000


Mr. Gwenael Hagan
Vice President of Corporate Development
Webb Interactive Services, Inc.
1800 Glenarm Place
Suite 700
Denver, CO  80202


Dear Gwenael,

Per our discussion on April 12, 2000, this letter documents our understanding of
participation by Diamond Partners Incorporated d/b/a Diamond Technology Partners
Incorporated ("Diamond") in Webb Interactive Services, Inc.'s (Webb) initial
efforts to commercialize the Jabber.org Open Source solution and create
Jabber.com, Inc.  This project will focus on identifying the appropriate
strategic path for Jabber.com, Inc. and ultimately converting that concept plan
into a complete business plan.  The plan will be created with the goal that it
be used to help raise funds and create partnerships in order to move the company
forward in its long-term goals.  Those next steps will include prototyping
multiple concepts and ultimately operationalizing the new business.  In creating
this Digital StrategySM, we will attempt to leverage Webb's and Diamond's
relationships with the Open Source community, Webb's existing internal efforts
on the Jabber platform, the Diamond Network of partners and Webb's understanding
of the instant messaging environment.

We are very excited to be an integral part of making the underlying promise of
Jabber become a commercial reality.  The race to dominate instant messaging has
been ongoing in the consumer marketplace for a number of years.  However, little
has been successfully done to connect the various networks, to bring instant
messaging into the business to business commerce world or to develop a vision
for the future of what instant messaging can become by connecting to other
technologies like XML and wireless communications.  It is this opportunity that
we hope to identify more clearly and communicate internally as well as
externally so that Jabber.com, Inc. has a coherent vision for its future.

If executed successfully, we believe that this opportunity will prove to be very
valuable for Webb.   The extent of that value will be determined as part of the
overall project and will help in focusing in on the appropriate strategic path.
Since this new opportunity extends beyond Webb's current business model, it

is critical that Webb proceeds carefully, targeting specific milestones rather
than instant profitability, without losing the element of speed. Existing
players are already attacking this market, so Webb needs to prototype and
implement rapidly in order to capture the opportunity while managing risk.

Therefore, Diamond proposes to assist Webb in rapidly developing a detailed
business plan, an economic model and a pitch presentation to gain the next round
of funding for Jabber.com, Inc.  Diamond has extensive experience helping large
and small companies scope and plan for new e-business ventures like this one.
Additionally, Diamond is uniquely positioned to assist Webb in this effort since
we can leverage the work we have already done around the Open Source community
and instant messaging to help develop the strategy and minimize the time it
takes to get a team `up to speed' with the concept.

The remainder of this letter presents our approach, deliverables, timeframe,
staffing and fees that we propose for this engagement.

Note:  Diamond's typical time frame to develop a Digital StrategySM for a
company is three months.  The end result is an extraventure business plan that
should be able to be financed by an external venture capital firm.  Our initial
discussions on this project with Webb have targeted an 8-week project, which
compresses the time frame and will require some tradeoffs for the speed of the
project.


Approach & Deliverables

Given the competitive nature of this marketplace and the opportunity we believe
exists for Jabber, Diamond believes that it is critical that Webb develop (or
ideate) potential `Killer App' concepts to commercialize very quickly.  Once
that is done with the help of the external advisors for Webb/Jabber and the
broader Diamond Network, then we will take those concepts and form a complete
business plan, an economic model and a pitch presentation.  Diamond will expect
to work collaboratively with the core Webb/Jabber team in developing these
potential `Killer Apps' and the ensuing business plan to ensure that the detail
knowledge of the opportunity remains with Jabber.com, Inc. going forward.

As part of the business plan, we will work with Webb to develop a refined
definition of the business concept, including specific products, services, and
partners.  We will also develop a high-level rollout plan that maps out

development of capabilities and service delivery from the prototype to end-state
implementation.  Next, we will define the value proposition for all key
constituents, including Webb, partners, suppliers, and customers.  Further, we
will design a high-level marketing strategy including branding and a
revenue/pricing model.  Then, we will develop a financial model that projects
"order-of-magnitude" revenue, operating costs, and capital requirement over the
next 5 years, outline key management team requirements, and discuss risks and
possible mitigants.  To the extent that we develop multiple products or
platforms, we will adjust the detail level of the financial model to fit the
compressed time frame.

All of these components will be integrated into a cohesive business plan that
can be used to evaluate and measure the opportunity from an internal and
external perspective.  For the pitch presentation, we will use our Media Lab
resources to work closely with the team to scope the requirements, define the
flow of the presentation and create the appropriate graphics and text to support
funding and partnership efforts.

A summary of the key engagement components is outlined below:

The professional fees for this engagement are $800,000 at full rates.  However,
Diamond has agreed to accept equity in lieu of fees in the amount of $140,000 or
17.5% of total fees.  This makes the professional fees due in cash to be
$660,000.  The equity arrangement is as follows:


1.   For the $140,000 discussed in the previous paragraph, Diamond will be
     entitled to the number of shares of capital stock of Jabber.com, Inc. equal
     to $140,000 divided by the price per share of the stock sold at the first
     round of external financing, such shares to be issued at the time of and on
     the same terms and conditions (e.g., class of capital stock, price per
     share, voting rights, registration rights, preemptive rights, anti-dilution
     protection, etc.) as those sold to the participating investors in the first
     round of external financing for Jabber.com, Inc.

2.   Diamond will also be entitled to purchase at the time of each financing
     round, on the same terms as other participants who participate in those
     financing rounds (at fair market value), up to 10% cumulatively (or such
     lesser amount as we may elect) of Jabber.com, Inc., with the proviso that
     the amounts invested by Diamond cannot exceed 30% of the total investment
     in Jabber.com, Inc. for each specific equity financing round up to Initial
     Public Offering. In addition, Diamond will receive their pro rata share of
     any friends and family allocation in connection with an IPO. This
     aforementioned right to purchase 10% cumulatively of Jabber.com, Inc.
     terminates upon an IPO, sale of substantially all of the assets of
     Jabber.com, Inc., or a merger of Jabber.com, Inc. with another company in
     which Jabber.com, Inc. shareholders do not constitute 50% of the combined
     companies' shareholders.

3.   Diamond will also make available Mark Siefertson, a Diamond Partner, to
     become a member of Jabber.com, Inc.'s advisory board, under the terms and
     conditions contained within the separately approved Advisory Board
     Agreement in exchange for 37,500 common shares.

4.   In exchange for the investment rights noted above and in addition to the
     appointment of a Diamond Partner to the advisory board, Diamond agrees on a
     good faith basis, as Diamond deems appropriate, to provide assistance
     relating to promotions, brand building, fundraising, revenue generation,
     partnership building, recruitment, and other key efforts related to
     building the company. It being understood that Diamond will continue to
     provide the aforementioned assistance subsequent to the conclusion of any

     consulting arrangement. It also being understood that all of Diamond's
     rights mentioned in this arrangement letter will survive.

5.   The foregoing equity arrangement shall apply to any successor-in-interest
     to the Jabber.com, Inc.'s business.


                            ***********************

DIAMOND'S TERMS AND CONDITIONS OF SERVICES
------------------------------------------

CONFIDENTIALITY

Diamond acknowledges that during the Project it may learn and use certain of
Client's confidential information and thus will use reasonable efforts to
prevent third parties from learning about such information.  Likewise, Client
will use reasonable efforts to prevent third parties from learning about
Diamond's confidential and proprietary information, which includes without
limitation Diamond's methodology, processes, programs and know-how.  These
obligations do not apply to information or materials that: 1) are or become
generally known by third parties other than as a result of an act or omission by
the receiving party; 2) were already independently known by the receiving party
prior to receiving them from the disclosing party; 3) are developed
independently by the receiving party; or 4) are required by law or a
governmental agency to be disclosed, provided the receiving party promptly
notifies the disclosing party of such requirement so that the disclosing party
can seek to obtain a protective order or similar remedy.  Diamond will act as an
independent contractor on the Project, and, unless otherwise specifically agreed
to by the parties, neither Diamond nor Client shall act as the agent or joint
venturer of the other.

PROPRIETARY RIGHTS

Except for previously developed ideas, concepts, know-how, knowledge,
techniques, tools, approaches, and methodologies proprietary to Diamond, as well
as any open source coding or software, which may be reflected in the
deliverables, Client shall have title to, ownership of, and all proprietary
rights in the deliverables provided by Diamond in connection with the Project,
including all work-in-progress; provided, however, that title to any such
proprietary rights shall not pass until Client's payment to Diamond therefor. At
Client's request, Diamond will execute such documents as may be necessary to
protect Client's rights in any work.

Nothing contained herein shall be construed as limiting Diamond's rights to use
or market in the conduct of Diamond's business, without obligation of any kind
other than Diamond's obligations of confidentiality to Client, any such pre-

LIMITATION ON LIABILITY

Diamond warrants that the services described in this proposal will be provided
in a professional manner.  Other than this warranty, Diamond makes and Client

purpose.  Client understands and agrees that any liability of Diamond regarding
the Project shall be limited to the amount of fees actually received by Diamond
in connection with the Project, and shall not include any special, incidental,
consequential or punitive damages, any damages based on injury to person or
property, or any lost sales or profits.

DISPUTE RESOLUTION

Diamond and you both agree that any dispute concerning the services that cannot
be resolved first by Diamond's and Client's respective chief executive officers
or other agreed-upon officers shall be arbitrated in accordance with the
commercial rules of the American Arbitration Association, and any award shall be
final and enforceable by a court.

CANCELLATION

Either Client or Diamond may terminate this Agreement by giving the other no
less than thirty (30) days advance written notice of termination, in which case
this Agreement shall terminate on the effective date specified in such notice
(which date shall not be less than thirty (30) days from the date of notice).
Either party may cancel this Agreement immediately, in whole or in part, for
material default, material breach, insolvency, bankruptcy, inability to pay
debts, or similar financial circumstances by the other. In the event of any such
termination, Diamond shall invoice the Client for any amounts due and

Diamond personnel perform services at Client's premises, Client will provide
reasonable office accommodations and services, including without limitation

by Diamond.  Client shall also furnish Diamond with all the data and information
required by Diamond for the Project, as well as reasonable access to key
personnel.

consult with, or otherwise retain the services of any of the employees who are
in any manner connected with the services as set forth in this proposal.

than once every three months, Diamond may increase its fee rates for services
provided.
