1.   Section 5(b) and (c) of the Original Agreement are hereby deleted and
     replaced in their entirety with the following sections 6(b), (c) and (d);
     the remainder of section 6 is renumbered accordingly:

"b) Revenue Sharing.
    ---------------

     1.   Definitions.
          -----------

     "Hospital Receipts" means revenues collected by Pointshare from hospitals
     located in Washington state for any services including but not limited to
     services for hospitals, physicians, MSOs, OP reference labs and other
     providers that are either owned by the hospital or for whom the hospital
     sponsors services. For purposes of this Agreement, "owned" shall mean
     control of at least 50% of the voting interests of an entity.

     "Government Receipts" means revenues collected by Pointshare from the
     specific government and non-government entities and agencies listed on
     Attachment F that are located or doing business in Washington State, and
     which relates to the activities of those entities and agencies in WA State,
     as such list is updated from time to time by mutual agreement of the
     parties; provided, however, revenues from the following entities or
     constituents shall not be included in Government Receipts: health insurance
     companies, health insurance third party administrators, physicians, home
     health agencies, suppliers or other organizations that provide health care
     directly to patients.

     "Non-Hospital Receipts" means all revenues collected by Pointshare from
     sources other than hospitals located in Washington State. These other
     sources consist primarily of physician revenue paid directly by physician
     groups.

     "Net Receipts" means receipts less charges for Third Party services. For
     example, if Pointshare or WHS collects $1,000 from subscribers for the MD
     Consult third party service, and MD Consult is, in turn, paid $800 for the
     use of the content by Pointshare, the Net Receipt is $200.

     "Pointshare-developed Applications" means those online services developed
     exclusively by Pointshare including but not limited to Multi-payer
     Eligibility Verification Service, ReferralPoint, ContactPoint, InfoPoint,
     Hospital Community Outreach services, Clinical Messaging and Pre-admit
     authorizations.

     "Third Party Services" means those online services provided by parties
     other than Pointshare and WHS including but not limited to CodeCorrect,
     QuadraMed and MD Consult that are accessed by Washington Health.Net
     subscribers from the Washington Heath.Net site.

     "WHS-developed Content" means those online services developed exclusively
     by WHS including but not limited to Washington Electronic Billing ("WEB")
     Services.

     2.   Revenues Sharing.
          ----------------

      (A) During the term of the Agreement, Pointshare shall pay WHS a fee equal
          to [***] of all Hospital Receipts and Government Receipts paid in
          connection with Pointshare-developed Applications. Pointshare is
          entitled to retain the balance of such Hospital Receipts and
          Government Receipts.

          entitled to retain the balance of such Hospital Receipts, Government
          Receipts, and Non-Hospital Receipts received in connection with WHS-
          developed Content.

          Receipts received by either party in connection with Third Party
          Services.

     (D)  With the exception of WHS-developed Content, neither party will be
          obligated to pay the other party any fee in connection with Non-
          Hospital Receipts received by such party.

"c) Payments. Payments owed in connection with Section 6(b) above shall be
    --------
payable to the other party within thirty (30) days following receipt of the
applicable Hospital Receipts.

"d) Warrant. In consideration of WSH and WSHA's collaboration and efforts
    -------
regarding Section 4(1), Promotion Outside Washington, Pointshare will grant
WHS, subject to Board approval, a warrant to purchase up to 5,000 shares of
Pointshare's Common Stock at an exercise price equal to $0.250, or such price as
is determined by Pointshare's Board of Directors to be the appropriate value for
the company's common stock as of the date of the board approval. The warrant
will have a term of five (5) years."

     the end of the last sentence in such Section:

6.   Section 6(f) of the Original Agreement (which after renumbering under this
     Addendum will be Section 8(f)) is amended as follows:

     "f) Survival of Terms. The provisions of Sections 2, 8, 9, 13, 14, 15, and
     16 of this Agreement, and all payment obligations accrued during the term
     of this Agreement, shall survive the expiration or termination of this
     Agreement for any reason. All other rights and obligations for the parties
     shall cease upon termination of this Agreement."

7.   A new Section 18 is added to the Original Agreement as follows:

                                       3

1.   Washington Health.Net: WHS and Pointshare will collaborate on the
     ---------------------
     development and delivery of a Washington Health.Net web site that will be
     the default landing page available for all WA state hospitals, payers, and
     providers. This will be a subscription web site with secure network
     connections from Pointshare, WSHA, WA hospitals, providers, and payers.
     The site will include links to WSHA virtual communities and other content,
     a pre-packaged bundle of Pointshare online service channels including but
     not limited to multi-payer Eligibility, ContactPoint Electronic Healthcare
     Directory, InfoPoint, and Pointshare and other third party premium
     channels.

2.   Other Enterprise Landing Pages: The larger supernet (statewide healthcare
     ------------------------------
     network connecting physicians, hospitals, health plans and other
     participants) is a collection of many subnets securely linked to Pointshare
     today. Pointhshare will continue to provide other portals to the same
     Pointshare content also available on Washington Health.net when clients
     want their own private-labeled site for a landing page. Examples include
     Providence Health Systems, Inland Northwest Health Services (INHS), Cascade
     Healthcare Alliance, Evergreen Community Health, the WA State Academy of
     Family Practice, and others.

3.   WEB Services. Pointshare and WHS will work together to evaluate
     ------------
     web-enabling the WEB services (described in Attachment E) and integrating
     such WEB services with the Pointshare services. If and to the extent
     Pointshare and WHS develop a web-enabled WEB service, the parties will a)
     negotiate in good faith a revenue sharing arrangement that reflects the
     relative contribution of the parties and b) Pointshare will work with WHS
     to develop a plan for Pointshare to install and support any new web--
     enabled version of the WEB services for Pointshare subscribers. WHS shall
     pay a reasonable fee to Pointshare for installation and professional
     services provided by Pointshare in connection with the web-enabled version
     of WEB.
