     Pointshare will prominently display OMA's logo and name on supplemental
     marketing literature directed to potential Physician Subscribers; provided,
     however, that OMA shall have the right to reasonable and timely opportunity
     to review and to approve or disapprove in writing all such marketing
     materials and advertising before use and implementation (such approval not
     to be unreasonably withheld).  If OMA fails to respond to Pointshare within

     OMA shall be deemed to have approved such materials.

6.   OMA RIGHTS AND RESPONSIBILITIES.

a)   Sponsorship and Promotion.  OMA will sponsor and promote Pointshare's

     services to Oregon Physicians and their community health partners such as

     activities to physicians will be as mutually agreed to and include
     providing newsworthy reports in the OMA monthly newsletter, promoting on
     the OMA web site, facilitating positioning for Pointshare in quarterly
     promotional inserts and at OMA meetings where exhibit space is available,
     and direct mail correspondences, all of which shall be at Pointshare's
     expense.  Sponsorship activities to community health partners will include
     telephone calls and some fact-to-face meetings.  The OMA shall without
     additional charge include newsworthy reports in the OMA newsletter and

          Physician Directory data for the purpose of  use within on-line
          Services set forth in Attachment C and sales activities, which
          information is understood to be confidential information.

     mutually agreed representative from the OMA will serve on Pointshare's

     --------------------------
     shall, without change, have the right to access the Service for the purpose
     of review and providing feedback to Pointshare. Such access shall be
     through the OMA's existing 56 KBPS frame connection, at OMA's expense. Any
     increase in access bandwidth or usage shall be mutually agreed  to by both
     parties, and any additional costs for increased bandwidth or usage will be
     the responsibility of the OMA.

7.   SPONSORSHIP REIMBURSEMENTS.

a)   Reimbursement to OMA for Sponsorship Activities.  During the term of
     -----------------------------------------------
     this Agreement, Pointshare will reimburse the OMA for sponsorship
     activities on a quarterly basis, based on the cumulative number of
     Physician Subscribers at the end of each calendar month, as set forth on
     Attachment A.

     --------------------------
     reimbursements accrued from the previous calendar quarter along with a
     report detailing the sponsorship reimbursements and Physician Subscribers
     for such quarter within 30 days following the end of the previous calendar
     quarter.

c)   Audit Right.  To verify the accuracy of sponsorship reimbursement due
     -----------
     under Section 7.a), Pointshare shall keep accurate books and records
     reflecting the names and numbers of Physician Subscribers as defined in
     2.e) above.  Pointshare shall permit an independent certified public
     accountant selected by the OMA to inspect such records at all reasonable
     times upon 48 hours' prior written notice at OMA's expense.  Pointshare
     shall pay the accountant fees if the inspection reveals an underpayment of
     reimbursements of more than ten percent (10%) in any quarterly reporting
     period. Upon termination of this agreement, the OMA will have 90 days to
     conduct a final audit.

8.   TERM AND TERMINATION.

a)   Agreement Term.  The term of this Agreement will commence on the
     --------------
     Effective Date and continue for a period of five (5) years (the "Initial
     Term") and thereafter shall automatically renew annually unless terminated
     by either party upon ninety (90) days written notice to the other party
     prior to and effective on the expiration of the current term.

b)   Termination.  Either party may terminate this Agreement prior to expiration
     -----------
     of the term: (a) if either party fails to perform any of its material
     obligations under this Agreement and such failure remains uncured for
     ninety (90) days (or in the case of failure to make a required payment,
     twenty (20) days) after receipt of written notice of default from the other
     party; or (b) if either party ceases to conduct business, becomes or is
     declared insolvent or bankrupt, files a petition in bankruptcy, is the
     subject of any proceeding relating to its bankruptcy, liquidation or
     insolvency which is not dismissed within thirty (30) days, appoints a
     receiver or liquidator of any of its properties or assets or makes an
     assignment for the benefit of its creditors.

c)   OMA recognizes that maintaining OMEN participation by health plans
     ("Plans") as well as increasing the number of those Plans participating are
     important elements in the continued success of the network. Pointshare
     recognizes that while the OMA plays a key role in this process, OMA can
     neither assure continued participation nor cause other Plans to
     participate. However, OMA will use its best efforts to educate presently
     participating Plans to the enhancements and benefits of transition of the
     OMEN network to Pointshare's stewardship. OMA will further use its best
     efforts to attract the interest of other Plans and will assist Pointshare
     in identifying and arranging meetings with Plan principals so Pointshare
     can make its case for participation. In the event a Plan signals its intent
     to withdraw from participation, OMA will use its best efforts to discourage
     withdrawal.

d)   Effect of Termination.  Upon termination of this Agreement, all of
     ---------------------
     Pointshare's service obligations (including Pointshare Services) to OMA and
     OMA's sponsorship of Pointshare Services (including any further right to
     receive sponsorship reimbursements) shall terminate.  Except as otherwise
     provided in this Agreement, within thirty (30) days after termination, each
     party will pay all fees and other charges due to the other party under this
     Agreement and will destroy or return to the other party all full or partial
     copies of the other party's Confidential Information and unused promotional
     materials in its possession or control.

e)   Limitation of Liability.  In the event of termination by either party in
     -----------------------
     accordance with any of the provisions of this Agreement, neither party
     shall be liable to the other, because of such termination, for
     compensation, reimbursement or damages on account of the loss of
     prospective profits or anticipated sales or on account of expenditures,
     inventory, investments, leases or commitments in connection with the
     business or goodwill of either party.  Termination shall not, however,
     relieve either party of any obligations incurred prior

                                       5

     to the termination, including, without limitation, the obligation of either
     party to pay to the other party the amounts owed as set forth in Section 4
     arising prior to such termination.

f)   Survival of Certain Terms.  The provisions of Section 2, 7c, 8, 9, 10, 12,
     -------------------------
     13 and 14 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 provided that provisions of Section 7c shall
     survive for only ninety (90) days following termination.  All other rights
     and obligations of the parties shall cease upon termination of this
     Agreement.

g)   Return of Property Other than Confidential Information.  Upon termination,
     ------------------------------------------------------
     Pointshare shall, within 10 days, return to the OMA the hardware and
     software (including upgrades) and other property transferred by Peregrin
     and the OMA through this Agreement as set forth in Attachment D.

9.   OPTION TO BUY-OUT AGREEMENT.  At any time following after six (6) months
     ----------------------------
     but before twenty four (24)  months of this Agreement, Pointshare may elect
     to buy-out its remaining rights and obligations under this Agreement from
     OMA, by paying a one-time cash payment of [* * *] to OMA (the "Buy-Out
                                                                    -------

     ------
     the OMA in this Agreement will include Sections 6 a), b), c), d) and e) for
     the duration of the initial term of this Agreement  and (ii) Pointshare
     will have no obligation to pay any further sponsorship reimbursements to
