Ladies and Gentlemen:

     We are counsel for Webb Interactive Services, Inc. which has filed a
Registration Statement on Form S-8 for the registration of 1,750,000 shares of
common stock, no par value per share, issuable under the Webb Interactive
Services, Inc. 2000 Stock Option Plan (the "Plan").

     In rendering the opinion hereinafter expressed, we have examined such
records and documents of the Company and such other documents and records and
made such factual investigation as we deemed necessary. From such examination we
are of the opinion that:

     When the shares of common stock, up to a maximum of 1,750,000 shares, are
     issued and paid for pursuant to the Plan, such shares will be duly and
     validly authorized and issued and fully paid and nonassessable.

     We hereby consent to the use of this opinion as an exhibit to such
registration statement and to the reference to our name therein.

                                            Very truly yours,
