                           embodied in or associated with the HealthChannel
                           Content. There are no implied licenses under this
                           Agreement, and any rights not expressly granted to a

                           promotional material or any of EarthLink's partners'
                           Web sites, but in each case only to the extent as
                           reasonably necessary for EarthLink to perform as
                           contemplated by this Agreement. EarthLink agrees not
                           to remove, conceal or reposition any copyright or
                           other proprietary notice, legal disclaimer, or any
                           credit-line or date-line contained in the
                           HealthChannel Content (or otherwise create the
                           impression that Earthlink is the owner of the
                           HealthChannel Content). EarthLink agrees to use the
                           HealthChannel Marks only in accordance with
                           applicable laws and the terms of this Agreement.

                  5.       TRADEMARK RESTRICTIONS. HealthChannel may terminate
                           the foregoing trademark license if, in its reasonable
                           discretion, EarthLink's use of the Marks tarnishes,
                           blurs or dilutes the quality associated with the
                           Marks or the associated goodwill and such problem is
                           not cured within ten (10) days of notice of breach.
                           Title to and ownership of HealthChannel's Marks shall
                           remain with HealthChannel. EarthLink shall use the

                           any action inconsistent with HealthChannel's
                           ownership of the HealthChannel Marks, and any
                           benefits accruing from use of such HealthChannel
                           Marks shall automatically vest in HealthChannel.

                  6.       THE SERVICES. HealthChannel shall provide the
                           HealthChannel Content through the Co-Branded Site in
                           full compliance with the Service Specifications set
                           forth in EXHIBIT C hereto. HealthChannel shall be a
                           customizable health news provider option on the
                           EarthLink Personal Start Page. HealthChannel shall
                           update its HealthChannel Headlines on a regular basis
                           so as to maintain its freshness of content and
                           newsworthiness. The HealthChannel Content accessible
                           through the EarthLink Site shall only link to the
                           Co-Branded Site. HealthChannel shall design, create,
                           edit, manage, update and maintain the Co-Branded Site
                           for the purpose of providing Internet users with
                           access to the HealthChannel Content on a twenty-four
                           (24) hours per day, seven (7) days per week basis,
                           such that the HealthChannel Content provided through
                           the EarthLink Site and on the Co-Branded Site will
                           retain parity with the HealthChannel Content provided
                           by HealthChannel to any third party or through the
                           main HealthChannel Site in terms of freshness of
                           content, services and features. HealthChannel shall
                           Co-Brand every page of the Co-Branded Site that is
                           accessible by EarthLink Members. During the Term,
                           HealthChannel agrees to (i) work diligently with
                           EarthLink to promote the HealthChannel Content on the
                           EarthLink Site, and (ii) assist EarthLink in a
                           commercially reasonable manner to foster usage and
                           enjoyment of the HealthChannel Content by EarthLink
                           Members on an on-going basis.

                  7.       GUARANTEED REFERRALS FEE. In exchange for the
                           Guaranteed Referrals more fully described in
                           Paragraph 2.2(c), HealthChannel shall pay to
                           EarthLink a nonrefundable fee of Thirty-Six Thousand
                           Dollars ($36,000) (the "Guaranteed Referrals Fee") as

                           the Effective Date, or on a Renewal Date, as
                           applicable; (ii) twenty-five percent (25%) ($9,000)
                           within thirty (30) days following the end of three
                           (3) months after the Effective Date, or of a Renewal
                           Date, as applicable; (iii) twenty-five (25%) ($9,000)
                           within thirty (30) days following the end of six (6)

                           end of nine (9) months after the Effective Date, or
                           of a Renewal Date, if applicable.

                  8.       ADDITIONAL REFERRALS. In addition to the Guaranteed
                           Referrals Fee, HealthChannel shall pay to EarthLink
                           the sum of Ten Cents ($.10) per each Referral
                           generated under this Agreement in excess of the
                           Guaranteed Referrals (the "Referrals Fee"). The
                           Referrals Fee shall be paid to EarthLink on a
                           cumulative basis within two weeks following the end
                           of each calendar month that the Referrals are
                           generated during the Initial Term and each Renewal
                           Term, if any, accompanied by a report from

                  9.       CUSTOMER SUPPORT. HealthChannel shall provide, in a
                           professional and workmanlike manner, customer support
                           regarding the HealthChannel Content offered to
                           EarthLink Members through the Co-Branded Site, and
                           the purchasing and ordering thereof. HealthChannel
                           hereby agrees and acknowledges that such customer
                           support shall be accessible by EarthLink Members
                           twenty-four (24) hours a day, seven (7) days a week,
                           through a toll free telephone number to be provided,
                           paid for and maintained exclusively by HealthChannel,
                           which shall be referenced in the Co-Branded Site.

                  10.      COMPETITIVE ADVERTISING. HealthChannel shall not
                           display advertising of any kind (co-operative or
                           otherwise) for, or otherwise promote in any way, any
                           EarthLink Competitive Services on any page of the
                           Co-Branded Site.

                  11.      PREMIERE PARTNERS. HealthChannel shall set aside and
                           reserve an amount of space situated on the uppermost
                           portion of the screen in every page of the Co-Branded
                           Site, which space shall be suitably sizable, in
                           EarthLink's reasonable discretion, in order to
                           incorporate branding from EarthLink Premiere
                           Partners. EarthLink Premiere Partners appearing on
                           the Co-Branded Site will not include any providers
                           that are primarily engaged in the health and medical
                           information industry. HealthChannel shall, upon
                           EarthLink's direction, incorporate such EarthLink
                           Premiere Partners branding into the space referenced
                           above in any or all pages of the Co-Branded Site.
                           HealthChannel agrees and acknowledges that EarthLink
                           may, in its sole discretion, from time to time add or
                           remove such EarthLink Premiere Partners branding from
                           the Co-Branded Site and that HealthChannel will work
                           together with EarthLink to incorporate any
                           modifications to such EarthLink Premiere Partners
                           branding. This presence must include at least one
                           logo, GIF or HTML link, or branding, and an amount of
                           text which shall be determined in EarthLink's sole
                           discretion. The parties will work together to create
                           designs that are suitable, in EarthLink's sole
                           discretion, for each and all of these Co-Branded
                           pages, and HealthChannel will provide EarthLink with
                           design specifications and sample designs within
                           fifteen (15) days after the Effective Date in order
                           to allow EarthLink to generate new EarthLink Premiere
                           Partners branding. HealthChannel shall execute any
                           changes to pages of the Co-Branded Site required
                           under this Section 2.1(k).

                  12.      USER INFORMATION. HealthChannel shall not send
                           unsolicited emails to any EarthLink Member.
                           HealthChannel may send promotional email messages to
                           EarthLink Members who elect to receive such emails,
                           through a registration process with HealthChannel
                           through which HealthChannel offers to the EarthLink
                           Member an opportunity to receive HealthChannel's
                           promotional email messages, and each HealthChannel
                           promotional email message will offer to the recipient
                           a means by which the recipient may unsubscribe to
                           such emailing list. Under no circumstances will
                           HealthChannel send or enable others to send email
                           messages to EarthLink Members which promote EarthLink
                           Competitive Services. In no event shall HealthChannel
                           offer to any third party a list which would permit
                           such third party to identify the HealthChannel user
                           as an EarthLink Member.

                  13.      REPORTS. Within fifteen (15) days after the last day
                           of each calendar month, each party will provide the
                           other party with a monthly report of Referrals and
                           user traffic generated hereunder from the EarthLink
                           Site to the Co-Branded Site.

                  14.      AUDIT. During the Term of the Agreement, and during
                           the one (1) year period immediately following the
                           Term, EarthLink shall have the right, upon reasonable
                           notice, during normal business hours, at EarthLink's
                           own expense, through an independent auditor chosen by
                           EarthLink, to audit HealthChannel's books, records
                           and logs that relate solely to the Guaranteed
                           Referrals Fee, the Referrals Fee or other payments
                           owed to EarthLink hereunder. If an audit of the
                           appropriate records, books of account or logs reveals
                           that HealthChannel has understated the amounts owed
                           to EarthLink under this Agreement for the

<PAGE>

                          period under audit, then HealthChannel shall promptly
                          pay any amounts owed to EarthLink. If the amount of
                          underpayment for the period under audit equals or
                          exceeds five percent (5%) of the total amount owed
                          during such period, then HealthChannel shall reimburse
                          EarthLink for all reasonable costs and expenses
                          incurred in connection with conducting the audit.

                  15.      TECHNICAL IMPLEMENTATION. HealthChannel shall work in
                           good faith with EarthLink Member Services and Support
                           regarding all technical implementation and
                           performance issues under this Agreement.

                  16.      LATE PAYMENT. All amounts owed by HealthChannel to
                           EarthLink hereunder not paid when due and payable
                           will bear interest from the date such amounts are due
                           and payable at the rate of 1.5% per month (or the
                           maximum rate allowed by law).

         B.       DUTIES AND OBLIGATIONS OF EARTHLINK. IN CONNECTION WITH THIS
                  AGREEMENT, EARTHLINK SHALL HAVE THE FOLLOWING DUTIES AND
                  OBLIGATIONS:

                  1.       TRADEMARK LICENSE. During the Term, and subject to
                           the provisions of Section 2.3, EarthLink grants to
                           HealthChannel a nonexclusive, nonsublicenseable,
                           nontransferable, fully paid-up license throughout the
                           Territory to display the EarthLink/Sprint Marks (as
                           defined in EXHIBIT A), the Premiere Partners' marks
                           and logos, and any and all intellectual property
                           rights contained therein exclusively on the
                           Co-Branded Site or in or on promotional material, but
                           only as such use is reasonably necessary for
                           HealthChannel to perform as contemplated by this
                           Agreement.

                  2.       TRADEMARK RESTRICTIONS. EarthLink may terminate the
                           foregoing trademark license if, in its reasonable
                           discretion, HealthChannel's use of the EarthLink
                           Marks tarnishes, blurs or dilutes the quality
                           associated with the EarthLink Marks or the associated
                           goodwill and such problem is not cured within ten
                           (10) days of notice of breach. Title to and ownership
                           of EarthLink's Marks shall remain with EarthLink.
                           HealthChannel shall use then EarthLink Marks exactly
                           in the form provided and in conformance with any
                           trademark usage policies provided by EarthLink.
                           HealthChannel shall not create any combination Marks
                           with the EarthLink Marks. HealthChannel shall not
                           take any action inconsistent with EarthLink's
                           ownership of the EarthLink Marks, and any benefits
                           accruing from use of such EarthLink Marks shall
                           automatically vest in EarthLink.

                  3.       GUARANTEED REFERRALS. During the Initial Term of this
                           Agreement or any Renewal Term, EarthLink shall
                           provide Three Hundred Sixty Thousand (360,000)
                           Referrals to HealthChannel (the "Guaranteed
                           Referrals"). If upon the scheduled date for
                           expiration of the Initial Term or Renewal Term,
                           EarthLink has failed to provide the Guaranteed
                           Referrals during such Initial Term or Renewal Term,
                           then such Initial Term or Renewal Term shall be
                           automatically extended until HealthChannel has
                           received, in the aggregate, the Guaranteed Referrals
                           and such failure shall not constitute a breach of
                           this Agreement; provided, however, that the Initial
                           Term or Renewal Term shall not be so extended if this
                           Agreement is terminated by either party early in
                           accordance with Sections 2.3, 3.1(b), 3.2(c), 6.2 or
                           EXHIBIT C of this Agreement.

                  4.       MANAGING THE CONTENT. EarthLink shall include the
                           HealthChannel Content as a customizable health news
                           provider on the EarthLink Personal Start Page.
                           EarthLink shall place three (3) to five (5)
                           HealthChannel Headlines within the health news area
                           of the EarthLink Personal Start Page. Notwithstanding
                           the foregoing, HealthChannel acknowledges and agrees
                           that EarthLink Members may cause the health news
                           provider accessible through the EarthLink Site to be
                           provider(s) other than HealthChannel. HealthChannel
                           acknowledges and agrees that EarthLink has other
                           promotional programs

<PAGE>

                          through which certain partners promote the EarthLink/
                          Sprint Service and provide new EarthLink Members to
                          EarthLink. HealthChannel further acknowledges and
                          agrees that certain promotional partners require the
                          ability to restrict the advertising that appears on
                          the EarthLink Site of EarthLink Members brought to
                          EarthLink through such promotional partner. Therefore,
                          HealthChannel agrees that EarthLink retains the right
                          to remove the HealthChannel Content from the EarthLink
                          Site (at EarthLink's sole discretion), in the event
                          that a promotional partner of EarthLink requires that
                          such a deletion or move be made, and then such
                          deletion or move will only be effective as regards the
                          EarthLink Site accessible by EarthLink Members brought
                          to EarthLink through the requesting promotional
                          partner.

                  THAN TEN (10) BUSINESS DAYS PRIOR TO THE REQUESTED RELEASE
                  DATE (THE OTHER PARTY SHALL NOT UNREASONABLY WITHHOLD OR DELAY

                  INCLUSION IN THE EARTHLINK SITE, AS EARTHLINK MAY CHOOSE IN

III.     REPRESENTATIONS AND WARRANTIES.

         A.       EARTHLINK. EARTHLINK REPRESENTS AND WARRANTS TO HEALTHCHANNEL
                  THAT:

                  1.       EarthLink has the power and authority to enter into
                           and perform its obligations under this Agreement; and

                  2.       EarthLink has the full right to grant or otherwise
                           permit HealthChannel to use EarthLink's Marks, the
                           Premiere Partners' marks and logos and is aware of no
                           claims by any third parties adverse to any of such
                           intellectual property rights except for Sprint's
                           ownership of its Marks contained in the co-branded
                           EarthLink/Sprint Marks. If EarthLink's intellectual
                           property rights are alleged or held to infringe the
                           intellectual property rights of a third party,
                           EarthLink shall, at its own expense, and in its sole
                           discretion, (i) procure for HealthChannel the right
                           to continue to use the allegedly infringing
                           intellectual property or (ii) replace or modify the
                           intellectual property to make it non-infringing;
                           provided, however, if neither option is possible or
                           economically feasible and if the inability to use
                           such intellectual property would cause a material
                           breach of this Agreement (as determined by
                           HealthChannel), HealthChannel may immediately
                           terminate this Agreement upon notice to EarthLink.

         B.       HEALTHCHANNEL. HEALTHCHANNEL REPRESENTS AND WARRANTS TO
                  EARTHLINK THAT:

<PAGE>

                  1.       HealthChannel has the power and authority to enter
                           into and perform its obligations under this
                           Agreement;

                  2.       HealthChannel and the HealthChannel Content shall at
                           all times comply with all local, state and federal
                           laws, rules and regulations of the United States
                           applicable to the Co-Branded Site, the HealthChannel
                           Content and HealthChannel's performance under this
                           Agreement; and

                  3.       HealthChannel has the full right to grant or
                           otherwise permit EarthLink to access the Co-Branded
                           Site, to use the HealthChannel Content and to use
                           HealthChannel's Marks, and is aware of no claims by
                           any third parties adverse to any of such intellectual
                           property rights. If HealthChannel's intellectual
                           property rights are alleged or held to infringe the
                           intellectual property rights of a third party,
                           HealthChannel shall, at its own expense, and in its
                           sole discretion, (i) procure for EarthLink the right
                           to continue to use the allegedly infringing
                           intellectual property or (ii) replace or modify the
                           intellectual property to make it non-infringing;
                           provided, however, that if neither option is possible
                           or economically feasible and if the inability to use
                           such intellectual property would cause a material
                           breach of this Agreement (as determined by
                           EarthLink), EarthLink may immediately terminate this
                           Agreement upon notice to HealthChannel.

         IV.      CONFIDENTIALITY. EACH PARTY ACKNOWLEDGES THAT COMPANY
                  INFORMATION MAY BE DISCLOSED TO THE OTHER PARTY DURING THE
                  COURSE OF THIS AGREEMENT. EACH PARTY AGREES THAT IT SHALL TAKE
                  REASONABLE STEPS, WHICH SHALL INCLUDE, AT A MINIMUM, THE STEPS
                  IT TAKES TO PROTECT ITS OWN COMPANY INFORMATION, TO PREVENT
                  THE DUPLICATION OR DISCLOSURE OF COMPANY INFORMATION, OTHER
                  THAN BY OR TO ITS EMPLOYEES OR AGENTS WHO MUST HAVE ACCESS TO
                  THE COMPANY INFORMATION TO PERFORM SUCH PARTY'S OBLIGATIONS
                  HEREUNDER, AND TO FINANCIAL INVESTORS, LENDING INSTITUTIONS
                  AND EACH OF THEIR ACCOUNTANTS AND LEGAL COUNSEL, WHO SHALL
                  EACH AGREE TO COMPLY WITH THE TERMS OF THIS SECTION 4. EACH
                  PARTY AGREES THAT IF IT IS REQUIRED BY LAW TO DISCLOSE THE
                  OTHER PARTY'S COMPANY INFORMATION, SUCH DISCLOSING PARTY MUST
                  FIRST GIVE WRITTEN NOTICE OF SUCH REQUIRED DISCLOSURE TO THE
                  OTHER PARTY AND MAKE A REASONABLE EFFORT TO OBTAIN A
                  PROTECTIVE ORDER REQUIRING THAT THE COMPANY INFORMATION SO
                  DISCLOSED BE USED ONLY FOR THE PURPOSES FOR WHICH DISCLOSURE
                  IS REQUIRED. EACH PARTY SHALL PROTECT THE OTHER PARTY'S
                  COMPANY INFORMATION DURING THE TERM AND FOR TWO (2) YEARS

         XIV.      TERM, RENEWAL AND TERMINATION.

                  A.       TERM. THE INITIAL TERM OF THIS AGREEMENT SHALL BE ONE

                           AGREEMENT SHALL AUTOMATICALLY RENEW (ANY SUCH RENEWAL
                           DATE REFERRED TO HEREIN AS A "RENEWAL DATE") FOR
                           SEPARATE, CONSECUTIVE ONE (1) YEAR TERMS ("RENEWAL
                           TERM(S)") UNLESS WRITTEN NOTICE OF TERMINATION IS

                           EXPIRATION OF THE INITIAL OR RENEWAL TERM. IF THE
                           GUARANTEED REFERRALS ARE NOT MET DURING ANY INITIAL

                           EXTENDED UNTIL SUCH GUARANTEED REFERRAL AMOUNT IS
                           MET, ACCORDING TO SECTION 2.2(c) OF THIS AGREEMENT.

                  B.       TERMINATION. THIS AGREEMENT MAY BE TERMINATED BY THE

a)       "Complete Outage". means the Co-Branded Site is not reachable by
EarthLink Members for fifteen (15) minutes or more; provided however, that
HealthChannel may perform major system upgrades and/or service maintenance on a
scheduled and pre-announced basis which may put the Co-Branded Site down for up
to eight (8) hours.

b)       "Partial Outage". means the Co-Branded Site is reachable by less than
ninety percent (90%) of EarthLink Members, or the response time for a 50K HTML
page is greater than thirty (30) seconds.

c)       "URL Errors". means any errors in URL's, missing pages, or typos in
URLs including any HealthChannel error that causes EarthLink to present an
incorrect URL on the EarthLink Site, or which causes EarthLink to attempt to
harvest information from an incorrect URL.

d)       "Data Handling Errors". means any incorrect handling of user data, such
as where an end user registers for a service that is then not delivered in the
manner promoted to the end user.

2.       RESPONSE TEAM. HealthChannel will at all times during the Term, and any
Renewal Term(s), and at HealthChannel's sole cost and expense, maintain, on a
twenty-four (24) hour, seven (7) days a week basis, a contact person responsible
for monitoring the Co-Branded Site. The contact person will be available to
EarthLink on a twenty-four (24) hour, seven (7) days a week basis by phone and
email for consultation on Service Interruption issues and to assist in the
restoration of service following a Service Interruption. HealthChannel will
provide EarthLink with the names and phone numbers and email addresses of its
contact person, and ensure that any changes to the contact information is
provided to EarthLink.

3.       ESCALATION PROCEDURES.

a)       In the event of a Complete Outage, the HealthChannel contact person
will contact EarthLink as soon as possible following HealthChannel's
identification of a Service Interruption and will notify EarthLink of the nature
of the Service Interruption and the estimated time of resumption of service.
HealthChannel's contact person will keep the EarthLink notified of progress in
resolving the Service Interruption. If the Service Interruption is estimated to
last longer than thirty (30) minutes, EarthLink will have the option, at
EarthLink's sole discretion, of:

                  i)       removing any links or references to the Co-Branded
                  Site from the EarthLink Site until such time that the Service
                  Interruption ceases; or

                  ii)      to redirect any links to any web address experiencing
                  a Service Interruption, to an explanatory page of EarthLink's
                  choosing. EarthLink may publish such explanatory page, and may
                  choose in its sole discretion the wording of any explanatory
                  messages on such page.

In the event HealthChannel experiences more than two (2) Complete Outages in any
six (6) month period, EarthLink may terminate the Agreement immediately upon
written notice to HealthChannel.

b)       Partial Outage. Shall be managed by HealthChannel in all respects
identically to a Complete Outage, except that EarthLink will not have the right
to remove any link or reference to the Co-Branded Site.

In the event HealthChannel experiences more than four (4) Partial Outages in any
six (6) month period, EarthLink may terminate the Agreement immediately upon
written notice to HealthChannel.

c)       URL Errors and Data Handling Errors. EarthLink will contact
HealthChannel with regards to any URL Error or Data Handling Error, and
HealthChannel will work in a commercially reasonable manner to repair such
Service

Interruption. EarthLink may remove any links or references on the EarthLink Site
to the Co-Branded Site until such time as the Service Interruption is repaired
to EarthLink's reasonable satisfaction. If the URL Error or Data Handling Error
is not corrected within seventy two (72) hours of first notification, EarthLink
would have the right to permanently remove any links or references on the
EarthLink Site to the Co-Branded Site.

4.       HEALTHCHANNEL NOTICE. HealthChannel will give EarthLink no less than
fifteen (15) days prior notice of any changes to its URLs, harvest
specifications, or any of its processes and procedures that will affect the
manner in which EarthLink harvests information off of the Co-Branded Site.<PAGE>

                             dated March 1, 1999 and

                        ONLINE LICENSE AGREEMENT ADDENDUM

         The terms of the Infoseek Corporation ONLINE LICENSE AGREEMENT
("License Agreement") for Ultraseek Server CCE Product Version 3.0 (the
"Software"), attached hereto as ATTACHMENT A, as modified hereby (collectively,
the "Agreement"), shall apply to use by BioLogix (also known as and hereinafter
referred to as "BIOLOGIX") of the Software on thehealthchannel.com WWW site
("The Health Channel Site").

1.       LICENSE

     A.  TERMS:

         1.       Subject to the terms and conditions of this Agreement, the
                  applicable maximum Number of documents and collections which
                  may be indexed under this license is 1,000,000 and 10,
                  respectively. Subject to the limitations of Paragraph 4 below,
                  the maximum Number of sites which may be indexed shall be
                  unlimited. The Software license key provided will enable the
                  Content Classification Engine.

         2.       Pricing: Pricing shall be based upon the number of queries
                  received per month on The Health Channel Site. BIOLOGIX will
                  pay to Infoseek a query rate of $4.00 per thousand queries,
                  subject to a nonrefundable, noncreditable minimum fee payable
                  as follows: (i) upon execution of this Addendum by BIOLOGIX
                  ("Execution Date") and attributable to the period beginning
                  upon delivery of the Software and ending on August 31, 1999,
                  BIOLOGIX shall pay to Infoseek ninety-seven thousand five
                  hundred dollars ($97,500) as the minimum fee for such period,
                  and (ii) a minimum monthly fee of sixteen thousand two hundred
                  and fifty dollars ($16,250) payable monthly in advance for
                  each subsequent month thereafter. Infoseek will credit
                  BIOLOGIX $21,000, which represents the unutilized prorated
                  remainder of the original Addendum dated March 12, 1999 (the
                  "Original Addendum"), against the minimum fee due from
                  BIOLOGIX as described above. The terms of this Addendum
                  supersede the terms of the Original Addendum.

         3.       On or before the tenth (10) business day of each calendar
                  month after the Execution Date, BIOLOGIX shall pay to Infoseek
                  any additional amounts owed in excess of the applicable
                  minimum monthly fee with respect to the previous calendar
                  month and BIOLOGIX shall submit to Infoseek with each fee
                  payment a statement detailing the calculation of the fee
                  payment. Infoseek shall have the right to retain a U.S.
                  nationally prominent or other mutually agreeable independent
                  auditor to whom BIOLOGIX shall allow reasonable access to
                  BIOLOGIX's applicable books of account and other records
                  relating to BIOLOGIX's obligations under this Agreement.
                  Access to BIOLOGIX's documentation shall be during BIOLOGIX's
                  regular business hours upon at least ten (10) days prior
                  written notice and may be conditioned upon the auditor
                  executing a confidentiality agreement in a form reasonably
                  acceptable to BIOLOGIX relating to the auditor's performance
                  of an audit hereunder. In the event that an audit discloses an
                  underpayment for any twelve (12) consecutive month period of
                  more than five percent (5%) of the aggregate amount due to
                  Infoseek, BIOLOGIX shall pay the reasonable costs of such
                  audit.

         4.       BIOLOGIX may use the Software only at The Health Channel Site
                  and shall limit use of the Software solely to index health and
                  directly health-related internet sites, subject to the
                  restriction that BIOLOGIX is authorized and hereby represents
                  and warrants to Infoseek that (i) it is authorized to index
                  such sites, (ii) that its entry into this Agreement does not
                  violate any agreement with any other party and that its use of
                  the Software to index the aforementioned sites will not
                  infringe any copyright, patent or any other proprietary right
                  of any third party, (iii) that its performance under this
                  Agreement, its use of the Software and the provision of its
                  service to users in conjunction therewith will conform to all
                  applicable laws and government rules and regulations, and (iv)
                  that it holds the necessary rights to permit the use of any
                  material, data or information (collectively, material)
                  accessible to users on The Health Channel Site; and that the
                  use, reproduction, distribution, or transmission of such
                  material will not violate any criminal or common law, any
                  statutory rights or any rights of any third parties,
                  including, but not limited to, such violations as infringement
                  or misappropriation of any copyright, patent, trademark, trade
                  secret, music, image, or other proprietary or property right,
                  false advertising, unfair competition, defamation, invasion of
                  privacy or rights of celebrity, violation of any
                  anti-discrimination law or regulation, or any other right of
                  any person or entity.

<PAGE>

         5.       Upon request by Infoseek and at Infoseek's sole discretion,
                  (i) The Health Channel's Homepage shall display the Infoseek
                  tagline "Powered by Infoseek", or other such tagline to be
                  provided by Infoseek (at the same font size displayed on The
                  Health Channel's Search Results Page); and (ii) an Internet
                  hyperlink back to Infoseek shall be displayed on The Health
                  Channel's Homepage in a manner subject to Infoseek's prior
                  approval. The display of such aforementioned Infoseek tagline
                  and Internet hyperlinks shall be changed and/or removed as may
                  be requested by Infoseek from time to time.

         6.       All search and results pages generated from the use of the
                  Software must attribute appropriate acknowledgement and
                  mutually agreed upon credit to Infoseek and shall display on
                  such pages proper acknowledgements of Infoseek's copyright,
                  trademark, or other proprietary rights. Further, each such
                  search and results page shall provide a mutually agreed upon
                  link back to Infoseek in a manner subject to Infoseek's
                  approval.

         7.       Infoseek may at its sole discretion, list The Health Channel
                  as a recommended site for selected health-related topics in
                  the Infoseek directory.

         8.       Infoseek may mirror the search index maintained by The Health
                  Channel, and use that index to provide a health-related search
                  capability on the Infoseek Service. If Infoseek does elect to
                  provide such a service, Infoseek will provide attribution in
                  the form of logo linked to The Health Channel adjacent to the
                  search box, or other branding acceptable to both parties.

         9.       Infoseek shall be the exclusive search service utilized by
                  BIOLOGIX for searching and indexing sites specified in
                  Paragraph 4 above.

         10.      In the event that The Health Channel site provides a general
                  Internet search page or link, in addition to the site search
                  provided by the Software, Infoseek shall be the exclusive
                  Internet search service listed.

         11.      Nothing in this Agreement shall preclude Infoseek and any of
                  Infoseek's related entities from negotiating and entering into
                  arrangements with other parties to create, for itself or
                  themselves create, a service similar to and/or competitive
                  with The Health Channel Site.

         12.      Infoseek may terminate this Agreement immediately upon breach
                  of any provision of this Agreement. Infoseek shall also have
                  the right to terminate this Agreement with respect to
                  BIOLOGIX'S ability to index the aforementioned health and
                  health-related Internet sites, without cause and upon at least
                  sixty (60) days prior written notice, effective at any time
                  after August 31, 1999. The rights and obligations specified as
                  surviving in Paragraph 8 of the License Agreement and the
                  rights and obligations specified in Paragraphs 3, 10, 13 and
                  14 hereof will remain in effect after termination or
                  expiration hereof. Upon termination of this Agreement,
                  BIOLOGIX shall either return to Infoseek all copies of the
                  Software or else destroy all such copies of the Software.

                  BioLogix shall have the right to terminate this agreement and
                  all associated payments at any point after August 31, 1999,
                  upon at least thirty (30) days prior written notice.

         13.      The parties to this Agreement are independent contractors.
                  Neither party is an agent, representative or partner of the
                  other party. Neither party shall have any right, power or
                  authority to enter into any agreement for or on behalf of, or
                  to incur any obligation or liability of, or to otherwise bind,
                  the other party. This Agreement shall not be interpreted or
                  construed to create an association, joint venture or
                  partnership between the parties or to impose any partnership
                  obligation or liability upon either party.

         14.      NOTICE: Any notices required or permitted to be given pursuant
                  to this Agreement shall be in writing, sent via certified
                  mail, return receipt requested, or delivered by hand,
                  addressed as set forth below or to such other address as may
                  be amended or modified only in writing to the other party, and
                  shall be deemed to have been given when received.
