      after the third year of the term, without cause, upon giving ninety (90)
      days' prior written notice. Any termination of this Agreement shall not
      release the Client from its obligations hereunder which by nature, or the

      percent (50%) of the Service Fee. Such invoices will be sent on a
      bi-weekly basis and in accordance with the cost per record set forth in

      the date due.

      A. If any disagreement arises out of or relating to this Agreement, the
      parties involved in the dispute shall meet to attempt to resolve the
      disagreement between them. If the controversy cannot be resolved, it shall
      be settled by arbitration in New York, New York in accordance with the
      rules of the American Arbitration Association then in effect, and judgment
      upon the award rendered by the arbitrator(s) may be entered in any court
      having jurisdiction. The parties agree to divide equally the costs of
      arbitration.

      B. Notwithstanding anything to the contrary which may now or hereafter be
      contained in the rules of the American Arbitration Association, the
      parties agree that a party shall have the right, upon receipt of the
      arbitrators decision to file within ten (10) days thereof a motion to
      reconsider. The arbitrator(s) thereupon will reconsider the issues raised
      by said motion and either confirm or modify the decision. The cost of such
      a motion for reconsideration will be borne by the moving party.

      C. Notwithstanding anything to the contrary contained herein or in the
      prevailing rules of the American Arbitration Association, neither party
      shall demand, submit application for or be entitled to collect attorney's
      fees or punitive

<PAGE>

      damages in any proceeding commenced under or pursuant to this arbitration
      provision.

IX.   Miscellaneous.

      A. Pricing Terms. The pricing terms presented by CVONet are valid for
      thirty (30) days from the date enclosed herein.

      B. Notice. Any notice required by this Agreement shall be deemed
      sufficient if it is in writing and delivered personally on the date of
      receipt, if it is sent by certified mail, return receipt requested on the
      third business day following posting, if it is sent by overnight mail by a
      nationally recognized carrier (e.g. Federal Express) on the next business
      day, and if it is sent via facsimile (with a copy to follow by any of the
      aforementioned methods), on transmission, in all cases addressed to the
      party at its principal office and to the party or his legal
      representatives at the addresses written above or to such other addresses
      as they may designated by giving notice pursuant to this Section.

      C. Governing Law. This Agreement shall be governed by and construed in
      accordance with the internal law of the State of New York without
      reference to conflict of law principles.

      D. Binding Effect; Assignment. This Agreement shall be binding upon and
      shall inure to the benefit of the parties and their respective heirs,
      legal representatives, successors, and assigns and may not be assigned by
      any Party except with the written consent of the other Party.

      E. Counterparts. This Agreement may be executed in any number of
      counterparts, each of which shall be deemed an original, but all of which
      shall together constitute one and the same instrument.

      F. Entire Agreement; Modification and Waiver. This Agreement constitutes
      the entire agreement between the parties hereto, and expressly supersedes
      or replaces any and all prior agreements between the parties, oral or
      written, with respect to the subject matter hereof. None of the terms or
      provisions hereof shall be modified or waived, except by a written
      instrument signed by a party against which modification, waiver or
      termination is to be enforced. No waiver of any one provision shall be
      construed as a waiver of any other provision and the fact that an
      obligation is waived for a period of time shall not be considered to be a
      continuous waiver. Without limiting the foregoing, no waiver of any breach
      or violation hereof shall be implied from forbearance or failure by CVONet
      to take action.

      G. Required Disclosure. The Parties further agree that CVONet shall retain
      and make available upon the request of Client for a period of four (4)
      years after the furnishing of Credentialing Services, the contract and
      books, documents and records which are necessary to certify the nature and
      extent of the costs thereof when requested by the Secretary of Health and
      Human Services or the


                                       7
<PAGE>

      Comptroller General, or any of their duly authorized representatives. The
      provision relating to the retention and production of documents is
      included because of possible application of Section 1861(v)(1)(I) of the
      Social Security Act to this Agreement; if this Section should be found to
      be inapplicable, then this clause shall be deemed to be inoperative and
      without force and effect.

      H. Severability. If any provision of this Agreement shall be held, be
      deemed to be or shall in fact be invalid, inoperative or unenforceable as
      applied to any particular case in any jurisdiction or jurisdictions, or in
      all jurisdictions or in all cases, because such provision conflicts with
      any constitution, statute, rule of public policy or for any other reason,
      such circumstance shall not have the effect of rendering the provision or
      provisions in question invalid, inoperative or unenforceable in any other
      jurisdiction. Or, if any other case or circumstance or of rendering any
      other provision or provisions herein contained invalid, inoperative or
      unenforceable to the extent that such other provision or provisions herein
      contained invalid, inoperative or unenforceable to the extent that such
      other provision or provisions are not themselves actually in conflict with
      such constitution, statute or rule of public policy. This Agreement shall
      be reformed and construed in any such jurisdiction or case as if such
      invalid, inoperative or unenforceable provision had never been contained
      herein and such provision performed so that it would be valid, operative
      and enforceable to the maximum extent permitted in such jurisdiction or in
      such case.

13. GENERAL PROVISIONS.

13.1 Governing Law. This Agreement will be governed and construed in accordance
with the laws of the State of New York without giving effect to principles of
conflict of laws. Both parties agree to submit to jurisdiction in New York and
further agree that any cause of action arising under this Agreement may be
brought in a court in Suffolk County, New York.

Website, Services and Hosting Services will comply with all applicable
international, national, and local laws and regulations. Customer shall make
best efforts to ensure that its Content and Website will comply with all
applicable international, national, and local laws and regulations.

13.3 Regulations have been proposed under the Health Insurance Portability and
Accountability Act of 1996 ("HIPAA") pursuant to which, among other things,
"Covered Entities" will be required to include in agreements with their
"business partners" certain provisions concerning security and privacy matters.
Under such regulations, Customer may be a "Covered Entity" and Neptune may be a
"business partner" of Customer by virtue of this Agreement. Customer will give
written notice to Neptune after the publication of final HIPAA regulations if
Customer determines that in its reasonable opinion, Neptune is a "business
partner" within the meaning of such regulations. Within a reasonable time
thereafter, as determined by Customer, Customer will submit to Neptune proposed
amendments to this Agreement designed to satisfy the relevant requirements of
such regulations ("HIPAA Amendments"). Neptune shall have 30 days to accept the
proposed HIPAA Amendments or to notify Customer that it wishes to negotiate the
wording of such amendments. Neptune's failure to timely notify Customer of its
desire to negotiate shall constitute acceptance of the proposed HIPAA
Amendments, which shall then be deemed to be part of this Agreement. If Neptune
shall timely notify Customer of its desire to negotiate the proposed HIPAA
Amendments, the parties shall then proceed to negotiate in good faith and with
reasonable diligence in an attempt to reach mutual agreement on the HIPAA
Amendments. Notwithstanding to the contrary contained herein, in the event that,
by the 90th day following Neptune's notice of its desire to negotiate, HIPAA
Amendments have not been mutually agreed to by reason of the failure of Neptune
to negotiate in good faith or with


                                       10
<PAGE>

reasonable diligence, Customer shall have the right to terminate this Agreement,
without liability or penalty of any kind, as of such date as Customer shall
determine.

13.4 Severability; Waiver. If any provision of this Agreement is held to be
invalid or unenforceable for any reason, the remaining provisions will continue
in full force without being impaired or invalidated in any way. The parties
agree to replace any invalid provision with a valid provision which most closely
approximates the intent and economic effect of the invalid provision. The waiver
by either party of a breach of any provision of this Agreement will not operate
or be interpreted as a waiver of any other or subsequent breach.

13.5 Headings. Headings used in this Agreement are for reference purposes only
and in no way define, limit, construe or describe the scope or extent of such
section or in any way affect this Agreement.

13.6 Assignment and Subcontracting. Neptune may not assign its rights, delegate
its duties pursuant to this Agreement to any person or entity without the
express nor written consent of Customer, such consent not be unreasonably
withheld. All or any part of the Website Maintenance and Hosting Services may be
performed by personnel employed or otherwise engaged by Neptune or any
subcontractor thereof, or other professionals who are not dedicated exclusively
to the provision of such services under this Agreement. Customer may assign,
transfer, delegate or grant all or any part of its rights pursuant to this
Agreement to any person or entity. The parties' rights and obligations will bind
and inure to the benefit of their respective successors and permitted assigns.

contractors, and no agency, partnership, joint venture or employee-employer
relationship is intended or created by this Agreement. Neither party shall have
the power to obligate or bind the other party. Personnel supplied by Neptune
shall work exclusively for Neptune and shall not, for any purpose, be considered
employees or agents of Customer. Neptune assumes full responsibility for the
acts of such personnel while performing services hereunder and shall be solely
responsible for their supervision, direction and control, compensation, benefits
and taxes. Client hereby acknowledges and agrees that nothing in this Agreement
is intended to be construed to prevent Neptune or its affiliates from entering
into similar Agreements with other entities.

appropriate party at the address specified below or at such other address as the
party shall specify in writing. Such notice shall be deemed given: upon personal
delivery; if sent by telephone facsimile, upon confirmation of receipt; or if
sent by certified or registered mail, postage prepaid, five (5) days after the
date of mailing.

13.9 Counterparts. This Agreement may be executed in one or more counterparts,
each of which shall be deemed an original and all of which shall be taken
together and deemed to be one instrument.

13.10 Injunctive Relief. Neptune hereby waives any right to injunctive relief or
rescission and agrees that its sole and exclusive remedy for any breach or
alleged breach, termination or cancellation of this Agreement by Customer shall
be an action for damages, including those


                                       11
<PAGE>

specified by Section 5.3, and termination of its services hereunder. Neptune
agrees that Customer may suffer irreparable harm in the event of any breach by
Neptune and that monetary damages in such event would be substantial and
inadequate to compensate Customer. Consequently, Customer shall be entitled, in
addition to such monetary relief as may be recoverable by law, to such
injunctive or other relief as may be necessary to restrain any threatened,
continuing or further breach by Neptune, without showing or proving actual
damage sustained by Customer and without posting a bond.

13.11 Insurance. Neptune shall, throughout the performance of its services
pursuant to this Agreement, maintain at its sole cost and expense: comprehensive

liability for injury or death to persons occurring from any cause whosoever that
may arise from or in connection with the performance of Neptune's services under
this Agreement or from or out of any negligent act of omission of Neptune, its
officers, directors and employees; and worker's compensation insurance and all
other employment related insurance coverage as required by applicable law.

13.12 Entire Agreement. This Agreement, including the Exhibits attached hereto,
sets forth the entire understanding and agreement of the parties and supersedes
any and all oral or written agreements or understandings between the parties as
to the subject matter of this Agreement. It may be changed only by a writing
signed by both parties. Neither party is relying upon any warranties,
representations, assurances or inducements not expressly set forth herein.

13.13 This Agreement shall be subject to written approval of the New York State
Department of Insurance.

      IN WITNESS WHEREOF, each of the parties hereto have executed this
Agreement as of the date first written above.
