         omissions disclosed by such audit. Any such audit shall be conducted

         (e.g., Deloitte) selected by HealthGate (other than on a contingent
         fee basis) and shall be conducted during regular business hours at
         HealthStream's offices and in such a manner as not to interfere with
         HealthStream's normal business activities. Any such audit shall be
         paid for by HealthGate unless Material discrepancies are disclosed.
         "Material" shall mean the lesser of Five Thousand Dollars
         (US$5,000.00) or five percent (5%) of the amount that should have been
         reported. If Material discrepancies are disclosed, HealthStream agrees

         be made more frequently than annually unless the immediately preceding
         audit disclosed a Material discrepancy. The auditor shall only
         disclose the correct data and amounts as called for on the royalty
         reports.

10.4.    Any statement shall affect neither the right to examine and audit nor
         the right to receive an adjustment to the contrary, appearing on
         checks or otherwise, unless expressly agreed to in writing by the
         party having such right.

10.5.    In the event that either party makes any claim with respect to an
         audit, upon the audited party's

         written request the party who has requested such audit will make
         available to the audited party the records and reports pertaining to

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER PARTY MAKES ANY OTHER

INCLUDING THOSE FOR MERCHANTABILITY AND/OR FITNESS FOR A PARTICULAR PURPOSE,
ARE EXPRESSLY EXCLUDED. NEITHER PARTY SHALL BE LIABLE FOR ANY CONSEQUENTIAL

                                   ARTICLE 12
                            NONDISCLOSURE AGREEMENT

12.1.    HealthStream expressly undertakes to retain in confidence all
         information and know-how transmitted to HealthStream by HealthGate
         that HealthGate has identified as being proprietary and/or
         confidential or that, by the nature of the circumstances surrounding
         the disclosure, ought in good faith to be treated as proprietary
         and/or confidential, and will make no use of such information and
         know-how except under the terms and during the existence of this
         Agreement. HealthStream shall not disclose, disseminate or distribute
         any such confidential information or know how to any third party
         without HealthGate's prior written consent. HealthStream agrees to use
         the same degree of care to protect HealthGate confidential information
         as HealthStream takes to protect its own confidential information of
         like importance. However, HealthStream shall have no obligation to
         maintain the confidentiality of information that:

         12.1.1.  Is received rightfully from another party prior to its
                  receipt from HealthGate;

         12.1.2.  HealthGate has disclosed to a third party without any
                  obligation to maintain such information in confidence; or

         12.1.3.  Has been or is independently developed by HealthStream.

12.2.    Further, HealthStream may disclose confidential information as
         required by governmental or judicial order, provided HealthStream
         gives HealthGate prompt notice of such order and complies with any
         confidentiality or protective order (or equivalent) imposed on such
         disclosure. HealthStream shall treat the terms and conditions of this
         Agreement as confidential; however, HealthStream may disclose such
         information in confidence to its immediate legal and financial
         consultants as required in the ordinary course of HealthStream's
         business. HealthStream's obligation under this Article 12 shall extend
         to the earlier of such time as the information protected

                                 Page 7 of 11
<PAGE>   8

         hereby is in the public domain through no fault of HealthStream or
         five (5) years following termination or expiration of this Agreement.
         HealthStream shall not disclose any information on HealthGate's
         unannounced products to HealthStream's employees or any third party.

12.3.    HealthGate shall have the same obligations in Sections 12.1 and 12.2
         above with respect to HealthStream's information and know-how. In
         addition, HealthGate shall treat all T.NAV(R) materials (including
         source code if obtained) as confidential information and shall not
         disclose, disseminate, or distribute such materials to any third party
         without HealthStream's prior written permission.

12.4.    Both parties shall prepare a mutually acceptable press release, if
         any, to announce this Agreement.

                                   ARTICLE 13
                                     AUDITS

13.1.    During the term of this Agreement, the parties hereto agree to keep
         all usual and proper records and books of account and all usual and
         proper entries relating to Transactions and sales of Ad Inventory
         consistent with generally accepted accounting principles.

13.2.    HealthStream may cause an audit to be made of the applicable
         HealthGate records that pertain to this Agreement for the sole purpose
         of verifying royalty reports issued by HealthGate to HealthStream and
         prompt adjustment shall be made to compensate for any errors or
         omissions disclosed by such audit. Any such audit shall be conducted
         by an independent certified public accountant of national stature
         (e.g., Deloitte) selected by HealthStream (other than on a contingent
         fee basis) and shall be conducted during regular business hours at
         HealthGate's offices and in such a manner as not to interfere with
         HealthGate's normal business activities. Any such audit shall occur no
         more than once per calendar year and within six (6) months of the end
         of the calendar year. HealthStream shall pay for any such audit unless
         Material discrepancies are disclosed. "Material" shall mean the lesser
         of Five Thousand Dollars (US$5,000.00) or five percent (5%) of the
         amount that should have been reported. If Material discrepancies are
         disclosed, HealthGate agrees to pay HealthStream the costs associated
         with the audit not to exceed Five Thousand Dollars (US$5,000.00). The
         auditor shall only disclose the correct data and amounts as called for
         on the royalty reports.

13.3.    HealthGate may cause an audit to be made of the applicable
         HealthStream records and facilities for the sole purpose of verifying
         any reports issued by HealthStream to HealthGate, and prompt
         adjustment shall be made to compensate for any errors or omissions
         disclosed by such audit. Any such audit shall be conducted by an
         independent certified public accountant of national stature (e.g.,
         Deloitte) selected by HealthGate (other than on a contingent fee
         basis) and shall be conducted during regular business hours at
         HealthStream's offices and in such a manner as not to interfere with
         HealthStream's normal business activities. Any such audit shall be
         paid for by HealthGate unless Material discrepancies are disclosed.
         "Material" shall mean the lesser of Five Thousand Dollars
         (US$5,000.00) or five percent (5%) of the amount that should have been
         reported. If Material discrepancies are disclosed, HealthStream agrees
         to pay HealthGate for the costs associated with the audit not to
         exceed Five Thousand Dollars (US$5,000.00). In no event shall audits
         be made more frequently than annually unless the immediately preceding
         audit disclosed a Material discrepancy. The auditor shall only
         disclose the correct data and amounts as called for on the royalty
         reports.

13.4.    Any statement shall affect neither the right to examine and audit nor
         the right to receive an adjustment to the contrary, appearing on
         checks or otherwise, unless expressly agreed to in writing by the
         party having such right.

13.5.    In the event that either party makes any claim with respect to an
         audit, upon the audited party's written request the party who has
         requested such audit will make available to the audited party the
         records and reports pertaining to such audit prepared by the
         independent auditor who performed such audit.

or to such other address as the party to receive the notice or request so
designates by written notice to the other.

                                   ARTICLE 15
                                     MEDIA

Each party agrees it will not use the other party's name, marks, or logos in
any advertising, promotional material, press release, publication, public
announcement, or through other media, written or oral, whether to the press, to
holders of publicly owned stock without the prior written consent of the other
party. Such consent shall not be unreasonably withheld or delayed. Accurate
statements made by either party as to the basic terms of this Agreement are
said to have the consent of the other party.

                                   ARTICLE 16
                                CONTROLLING LAW

16.1     This Agreement shall be construed and controlled by the laws of the
         State of Tennessee.

16.2     Neither this Agreement, nor any terms and conditions contained herein,
         shall be construed as creating a partnership, joint venture or agency
         relationship or as granting a franchise as defined in 16 CFR Section
         436.2(a). The price and payment described in Article 4 of this
         Agreement shall be construed as a royalty fee for the rights granted
         in Article 3 of this Agreement, and not as a franchise fee.

                                   ARTICLE 17
                                ATTORNEYS' FEES

If either HealthStream or HealthGate employs attorneys to enforce any rights
arising out of or relating to this Agreement, the prevailing party in any
proceeding shall be entitled to recover its reasonable attorneys' fees, costs
and other expenses.

                                   ARTICLE 18
                                    GENERAL

18.1     This Agreement does not constitute an offer by HealthStream and it
         shall not be effective until

                                 Page 9 of 11

         signed by both parties. Upon execution by both parties, this Agreement
         shall constitute the entire agreement between the parties with respect
         to the subject matter hereof and replaces and supplants all prior and
         contemporaneous communications. It shall not be modified except by a
         written agreement signed on behalf of HealthGate and HealthStream by
         their respective duly authorized representatives. Unless agreed to in
         a separate writing signed by both parties, any statement appearing as
         a restrictive endorsement on a check or other document which purports
         to modify a right, obligation or liability of either party shall be of
         no force and effect.

18.2     If any provision of this Agreement shall be held by a court of
         competent jurisdiction to be illegal, invalid, or unenforceable, the
         remaining provisions shall remain in full force and effect. If this
         Agreement as it relates to any product(s) licensed hereunder shall be
         held by a court of competent jurisdiction to be invalid, illegal, or
         unenforceable or if this Agreement is terminated as to particular
         product(s), this Agreement shall remain in full force and effect as to
         the remaining product(s).

18.3     No waiver of any breach of any provision of this Agreement shall
         constitute a waiver of any prior, concurrent or subsequent breach of
         the same or any other provisions hereof, and no waiver shall be
         effective unless made in writing and signed by an authorized
         representative of the waiving party.

18.4     The Article headings used in this Agreement and the attached Exhibits
         are intended for convenience only and shall not be deemed to supersede
         or modify any provisions.

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date set forth in Section 1.8 above. All signed copies of this Agreement shall
be deemed originals.
