                                    EXHIBIT A

                             DESCRIPTION OF SERVICES

A-1      PRIVATE-LABEL CONTRACTOR MATCHING. ImproveNet agrees to provide its
         Contractor Matching Service to OC on a Private-Label basis. That is,
         ImproveNet will provide an OC branded Contractor Matching Service
         through OC's Internet home page and OC's toll-free telephone number.
         Such service to be marketed as OC's "Do-it-for-me" Service ("DIF-Me")
         or such other name as OC may select. In all situations where DIF-Me
         brand is prominently displayed, it shall be followed by the text
         "powered by ImproveNet" or such other text as may be agreed to by the
         parties. Where OC publishes information regarding the structure and
         functionality of the DIF-Me program, OC will use reasonable efforts to
         include therein a reference to ImproveNet and an explanation of
         ImproveNet's role in the DIF-Me program, but in no event shall OC have
         any liability for its failure to so reference ImproveNet.

         Customer leads generated through the DIF-Me program will be routed
         directly to ImproveNet and managed through its Contractor Matching
         Service. All OC-Generated Jobs will be directed, on a priority basis to
         OC's "Preferred Contractors" (as defined below). If no Preferred
         Contractor is successfully matched to the OC-Generated Job within
         forty-eight (48) hours, ImproveNet shall have the right to match such
         OC-Generated Job to other ImproveNet Contractors.

A-2      PREFERRED CONTRACTOR SCREENING. OC and/or OC's wholly-owned
         subsidiaries, has developed a promotional program with certain
         contractors that satisfy and continuously maintain certain criteria
         ("Preferred Contractors"). Such ImproveNet qualified Preferred
         Contractors shall be those to whom ImproveNet shall direct OC-Generated
         Jobs. These Preferred Contractors are subjected to an initial
         certification and ongoing re-certification by OC in order to maintain
         their "Preferred" status. ImproveNet agrees to screen and qualify
         contractors for inclusion as Preferred Contractors on behalf of OC in
         accordance with selection criteria which are mutually agreed upon by OC
         and ImproveNet. During the Term of this Agreement, ImproveNet shall
         assist OC with the recruitment of ImproveNet qualified contractors to
         OC's Preferred Contractor Program.

A-3      ADVERTISING AND PROMOTIONAL SERVICES. During the Term of this
         Agreement, ImproveNet shall provide the following advertising and
         promotional services to OC, or at the request of OC, to any
         wholly-owned subsidiary of OC (provided that if OC requests ImproveNet
         to perform such services for an OC subsidiary, such services will be
         performed in lieu of, rather than in addition to, providing such
         services to OC):


                                      17.

<PAGE>


         A. BANNER ADVERTISING. OC will be represented with continuous banner
advertisements on the ImproveNet Consumer Site and the ImproveNet ProSite at all
time over the term of the Agreement. The style, format and content of such
banner advertising shall be determined by OC in consultation with ImproveNet.

         B.       BUTTON ADVERTISING. OC will be represented with a continuous
                  presence on the "button bar" in the relevant sections of both
                  the ImproveNet Consumer Site and ProSite. Each OC product line
                  will be represented on the appropriate pages. The style,
                  format and content of such button shall be determined by OC in
                  consultation with ImproveNet.

         C.       ON-LINE PRODUCT BROCHURE. OC's home and building related
                  products will be continuously featured in an on-line product
                  brochure on the ImproveNet Consumer Site and the ProSite (if
                  such brochure is offered on the ProSite). Such brochures will
                  link directly to the appropriate section of OC's Internet home
                  page. The placement of OC brochures will be at least as good
                  as any other brochure on the site. The specific products
                  included in the brochure, as well as the style, format and
                  content of the brochure shall be determined by OC, in its sole
                  discretion but after consultation with ImproveNet.

         D.       CONSUMER SMARTLEADS. OC has the right to submit SmartLeads to
                  every ImproveNet customer initiating on the OC site and the
                  ImproveNet system who submits a job related to any of OC's
                  product lines throughout the term of this Agreement. In
                  addition, OC will receive an additional 15,000 SmartLeads per
                  Contract Year during the Term of this Agreement to use, at its
                  discretion, from customers initiating on other manufacturers'
                  sites (e.g., "Find-a-Contractor"). ImproveNet will seek the
                  permission of the respective manufacturer from whose site the
                  customer originated ("Host Manufacturer") for OC to submit the
                  SmartLeads. The Host Manufacturer retains the full authority
                  to accept or reject OC SmartLeads to consumers originating on
                  its site. OC, as a Host Manufacturer will also retain this
                  "veto" right regarding SmartLeads from other manufacturers to
                  consumers generated by OC. OC SmartLeads will be consistent in
                  nature (e.g., currently 3 messages per lead) with those agreed
                  to by other manufacturers in standard signed insertion orders.

         E. CONTRACTOR SMARTLEADS. OC has the right to submit SmartLeads to
every ImproveNet contractor responding to a job related to any of OC's product
lines throughout the Term of this Agreement that is generated either by OC or by
the ImproveNet system, provided that such contractor has not opted out of
receiving such third-party promotions. These leads will be submitted to
contractors who are both online and not online through a combination of emails
via the ProSite and fax via the SmartPro


                                      18.

<PAGE>

fax. In addition, OC will receive an additional 15,000 SmartLeads per
Contract Year throughout the Term of this Agreement subject to the host
manufacturer rules as specified in Section D above, on the contractor ProSite
to use at its discretion. OC SmartLeads to contractors will be consistent in
nature with those agreed to by other manufacturers in standard signed
insertion orders.

         F. CONTENT INTEGRATION ON IMPROVENET. OC products will continuously
appear in the relevant sections of ImproveNet's Product Showcase. OC will have
the right to have OC products listed in at least as many total listings under
each of the relevant product categories as any other manufacturer displayed,
ImproveNet will work closely with OC to develop advertorial material that will
appear no less than three months each Contract Year in the relevant section of
the ImproveNet Consumer Site and ProSite, assuming that suitable material is
available from OC.

         G. HOT LINKS. The ImproveNet Consumer Site and ProSite will be
continuously "hot linked" to the OC Internet site in all places where OC
products are referenced.
