      due authorization, execution and delivery by Purchasers, constitutes a
      legal, valid and binding obligation of Seller, enforceable in accordance

      default) under any note, bond, mortgage, indenture, contract, agreement,
      lease, license, permit, franchise or other instrument or obligation to
      which Seller is a party or by which Seller is bound, or to which any of
      its properties or assets is subject.

            (d) To the extent the Purchasers do not have any knowledge to the
      contrary, Seller has good and marketable title to the Assets, free and
      clear of any liens, claims, encumbrances, rights or equities whatsoever of
      any third party. Purchasers will receive, as of the Closing Date, all of
      Seller's complete and exclusive rights, title, and interests in and to the

<PAGE>

            (e) To the extent the Purchasers do not have any knowledge to the

      rights, or equities whatsoever of any third party.

            (f) No litigation regarding the Site, the content of the Site, or
      the Assets is pending or has been threatened since July 31, 1999.

            (g) To Seller's knowledge, all copyright registrations, or
      applications therefor, with respect to the Copyright Interests are listed
      on Schedule 4.1(g).

      or similar registrations, or applications therefor, with respect to the
      Trademark Interests are listed on Schedule 4.1(h).

            (i) To Seller's knowledge, all agreements, arrangements or
      understandings in effect with respect to the Assets are listed on Schedule
      4.1(i).

            (j) Seller has not been a party to any license or other agreement
      related to the Site or its content requiring the payment of a royalty
      since July 31, 1999.

            (k) Seller has and will convey to Purchasers at the Closing good and
      marketable title to the Assets free and clear of all liens, pledges,
      security interests, charges, claims, restrictions and encumbrances of any
      nature whatsoever.

            (l) There are no existing agreements, options, commitments or rights
      with, of or to any person to acquire any of the Assets or any interest in
      the Site.

            (m) No representation, warranty or covenant made by Seller in this

      material fact.

            (n) Seller does not use any of the customer information it receives

      rights of privacy of its customers. To the extent the Purchasers do not

      collected personally identifiable information from viewers of the Site
      except in a manner disclosed in a privacy statement prominently displayed

      contrary, Seller has reasonably adequate security measures in place to

      any information it receives from its customers from the Site.

      and, assuming the due authorization, execution and delivery by Seller,

      may be limited by bankruptcy, insolvency, reorganization, moratorium and
      other similar laws of general applicability relating to or affecting
      creditors' rights generally and by the application of general principles
      of equity.

            (c) The execution and delivery of this Agreement by Purchaser does
      not, and the performance by Purchaser of his or her obligations under this
      Agreement, will not, result in any breach of or constitute a default (or
      an event which with notice or lapse of time or both would become a
      default) under any note, bond, mortgage, indenture, contract, agreement,
      lease, license, permit, franchise or other instrument or obligation to
      which Purchaser is a party or by which Purchaser is bound, or to which any
      of their properties or assets is subject.

fully the transfer of ownership of all of the Assets to Purchasers. Seller
therefore agrees:

            (a) To execute, acknowledge, and deliver any affidavits or documents
      of assignment and conveyance regarding the Assets reasonably requested by
      Purchasers;

            (b) To provide testimony in connection with any proceeding affecting
      the rights, title, or interests of Purchasers in the Assets; and

            (c) To perform any other acts Purchasers reasonably deem necessary
      to carry out the intent of this Agreement.

                                   SECTION 6
                                    RESERVED

                                   SECTION 7
                            ACKNOWLEDGMENT OF RIGHTS

      In furtherance of this Agreement, Seller hereby acknowledges that, from
and after the Effective Date, to the Seller's knowledge, Purchasers have acceded
to all of Seller's rights, title, and standing to:

                                       7

<PAGE>

            (a) Receive all rights and benefits pertaining to the Site and the
      Assets;

            (b) Institute and prosecute all suits and proceedings and take all
      actions that Purchasers, in their sole discretion, may deem necessary or
      proper to collect, assert, or enforce any claim, right, or title of any
      kind in and to any and all of the Site and the Assets; and

            (c) Defend and compromise any and all such action, suits, or
      proceedings relating to such transferred and assigned rights, title,
      interest, and benefits, and perform all other such acts in relation
      thereto as Purchasers, in their sole discretion, deem advisable.

                                   SECTION 8
                                 INDEMNIFICATION

      8.1 Seller agrees to indemnify and hold harmless Purchasers, its
successors and assigns, including any subsidiary, officer, director, employee,
agent, contractor, licensee or customer, from and against any loss, liability,
claim or damage (including court costs and Attorneys' fees) sustained by it or
them as a result of (1) any liability or obligation relating to the Assets, the
Site or any of the content not expressly assumed by Purchasers (a "Commercial
Claim"), or (2) any breach by Seller of any of its representations, warranties
or covenants under this Agreement (a "Misrepresentation Claim") (all of which
will survive Closing of this Agreement for a period of two (2) years from the
Closing Date), provided, however, absent fraud, that the total maximum financial
liability of Seller hereunder shall not exceed an amount equal to $1,000,000
plus court costs, Attorneys' fees and other defense costs not to exceed $500,000
in the aggregate.

      8.2 Nothing in this Section 8.2 is intended to limit any legal or
contractual obligation of Seller in the event of fraud by Seller. Otherwise,
however, Seller shall have no indemnification liability under Section 8.1,
unless it has received from Purchasers written notice of the alleged loss,
liability, claim or damage within a reasonable time after the loss, liability,
claim or damage arises and, in any event, prior to the second (2nd) anniversary
of the Closing Date (the "Claim Notice"). Furthermore, Seller shall have no
indemnification liability with respect to a Commercial Claim, unless Seller is
given (i) the right to control and direct the investigation and defense of such
claim and (ii) the right to control the settlement thereof so long as any such
settlement proposes no obligations or liabilities on Purchasers.

                                   SECTION 9
                         CONDITIONS TO THE OBLIGATION OF

EXHIBIT A

                       ASSIGNMENT OF INTELLECTUAL PROPERTY

         THIS ASSIGNMENT OF INTELLECTUAL PROPERTY (the "ASSIGNMENT"), made and
entered into as of the 31st day of January, 2001, by and between Alan Greene,
M.D., an individual resident of California ("AG"), Cheryl Lorraine Greene, an
individual resident of California ("CLG;" together with AG collectively, the
"PURCHASERS"), and adam.com, Inc., a Georgia corporation ("ASSIGNOR").

                                   WITNESSETH:

         WHEREAS, pursuant to that certain Asset Purchase Agreement dated as of
January 31, 2001 by and among Purchasers and Assignor (the "PURCHASE
AGREEMENT"), Assignor has agreed to sell, transfer, and assign the Assets (as
defined therein) to Purchasers;

         WHEREAS, Assignor is the owner and holder of the Copyright Interests
and Trademark Interests and all of the goodwill associated therewith
(collectively, the "INTELLECTUAL PROPERTY") relating to the Assets;

         WHEREAS, Assignor desires to assign (other than as expressly excepted
below) to Purchasers all of Assignor's rights, title, and interests in and to
the Intellectual Property, and Purchasers desires to accept such assignment; and

         WHEREAS, unless otherwise defined herein, the capitalized terms used
herein shall have the meanings ascribed to them in the Purchase Agreement.

         NOW, THEREFORE, for and in consideration of the premises and the
consideration provided in the Purchase Agreement, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged:

                                    SECTION 1
                             TRANSFER AND ASSIGNMENT

         1.1 CONVEYANCE OF RIGHTS. Assignor hereby transfers, grants, conveys,
assigns, and relinquishes exclusively to Purchasers all of Assignor's rights,
title, and interests in and to the Intellectual Property, in perpetuity (or for
the longest period of time otherwise permitted by law), including all rights,
title, interests, and benefit (including copy, adapt, distribute, display, and
perform under copyright law; and to use and disclose under trade secret law) of
Assignor in and to the Copyright Interests and the Trademark Interests
(including, in the case of trademarks, service marks and trade names, all
goodwill appertaining thereto), and all other intellectual property rights owned
or claimed by Assignor embodied in the Intellectual Property, specifically
including (without limitation) the registrations and applications listed in
SCHEDULE 1 hereto.

         1.2 FURTHER ASSURANCES. Assignor shall execute and deliver, from time
to time after the

                                       1

<PAGE>

date hereof upon the request of Purchasers, such further conveyance instruments,
and take such further actions, as may be necessary or desirable to evidence more
fully the transfer of ownership of all the Intellectual Property to Purchasers,
or the original ownership of all the Intellectual Property on the part of
Purchasers, to the fullest extent possible. Assignor therefore agrees to:

         1.       Execute, acknowledge, and deliver any affidavits or documents
                  of assignment and conveyance regarding the Intellectual
                  Property,

         2.       Provide all reasonable assistance in connection with any
                  proceeding affecting the rights, title, interests, or benefit
                  of the Company and to the Intellectual Property, PROVIDED THAT
                  any out of pocket expenses associated therewith shall be borne
                  by Purchasers, and

         3.       Perform any other acts deemed necessary to carry out the
                  intent of this Agreement.

including all copies of such materials and all documentation prepared or
produced in connection therewith, pertaining to the performance of Employee's
services for the Company, the business of the Company or of the Associated

Section VI. Ownership of Employee Developments.

      6.1 Ownership of Work Product.

      (a) Employee agrees to promptly report and disclose to the Company in
writing all developments, discoveries, methods, processes, designs, inventions,
ideas, or improvements conceived, made, implemented, or reduced to practice by
Employee, whether alone or acting with others, whether or not patentable or
registerable under copyright or similar statutes, during Employee's period of
employment by the Company, that are developed while utilizing, directly or
indirectly, the Company's equipment, supplies, facilities, or trade secret
information (hereinafter collectively called "Work Product"). Employee
acknowledges and agrees that all Work Product is the sole and exclusive property
of the Company. Employee agrees to assign, and hereby automatically assigns,
without further consideration, to the Company any and all rights, title, and
interest in and to all Work Product; provided however, that this Paragraph

facilities, or trade secret information of the Company was used and which was
developed entirely on Employee's own time, unless the Work Product results from
any work performed by Employee for the Company. Employee shall execute the
attached Schedule B, which acknowledges that Employee has received written
notification of his rights relating to inventions developed by Employee.

      (b) The Company, its successors and assigns, shall have the right to
obtain and hold in its or their own name copyright registrations, trademark
registrations, patents and any other protection available to the Company with
respect to the Work Product. Additionally, any works of authorship that Employee
prepares primarily for publication, and is published, on a web site for the
Company will be deemed "works made for hire" within the meaning of 17 U.S.C. ss.
101 (Section 101 of the Copyright Act), the copyright of which will be owned
solely and exclusively by the Company. If any such work of authorship that
Employee produces is protectible by copyright but does not constitute a "work
made for hire" within the meaning of 17 U.S.C. ss. 101 (Section 101 of the
Copyright Act), then that work will be deemed assigned to Company, and Employee
hereby assigns all right, title and interest, including worldwide copyright, in
and to that work to the Company. Employee hereby irrevocably relinquishes for
the benefit of the Company and its assigns any moral rights recognized by
applicable law in such works of authorship that Employee produces.

      6.2 Cooperation. Employee agrees to perform, upon the reasonable request
of the Company, during and after employment, such further acts as may be
necessary or desirable to transfer, perfect, and defend the Company's ownership
of the Work Product, including but not limited to: (a) executing, acknowledging,
and delivering any requested affidavits and documents of assignment and
conveyance; (b) assisting in the preparation, prosecution, procurement,
maintenance and enforcement of all copyrights and/or patents with respect to the
Work Product in any countries; (c) providing truthful testimony in connection
with any proceeding affecting the right, title, or interest of the Company in
any Work Product; and (d) performing any other acts deemed necessary or
desirable to carry out the purposes of this Agreement. The Company shall
reimburse all reasonable out-of-pocket expenses incurred by Employee at the
Company's request in connection with the foregoing.

      7.1 Employee acknowledges that during the course of his employment with
the Company Employee has received or may receive and has had or may have access

Associated Companies, possibly including but not limited to confidential and
secret business and marketing plans, strategies, and studies, detailed product
information or product development information, detailed client/customer lists,
and information relating to the operations and business requirements of those
clients/customers. Accordingly, Employee is willing to enter into the covenants
contained in this Agreement in order to provide the Company with what Employee
considers to be reasonable protection for its interests.

      7.2 Employee acknowledges that the restrictions, prohibitions and other
provisions in this Agreement are reasonable, fair, and equitable in scope,
terms, and duration; are necessary to protect the legitimate business interests
of the Company; and are a material inducement to the Company to employ or
continue to employ Employee.

Section VIII. Restricted Business Practices.

      It is the policy of the Company not to receive any confidential or
proprietary information from any employee arising in connection with the former
employment of said employee (except for self-employment), irrespective of
whether such information was received purposely or inadvertently. Employee is
expressly prohibited from having said confidential or proprietary information on
any Company property. Employee warrants that he has no information, whether
written, oral, tangible, or intangible, which can be construed as the property
of a former employer (excluding himself), and further that Employee will make no
use of any such information in the performance of Employee's duties on behalf of
the Company.

Section IX. Severability.

      In the event that any provision of this Agreement is held invalid or
unenforceable in any circumstances by a court of competent jurisdiction, the
remainder of this Agreement, and the application of such provision in any other
circumstances, shall not be affected thereby. In such event, the affected
provision will be deemed modified to the extent necessary to render such
provision enforceable, and the rights and obligations of the parties will be
construed and enforced accordingly, preserving to the fullest permissible extent
the intent of the parties.

Section X. Governing Law.

Section XI. Assignment.

      Employee acknowledges that the services to be rendered by him are unique
and personal. Accordingly, Employee may not assign any of his rights or delegate
any of his duties or obligations under this Agreement. The rights and
obligations of the Company shall inure to the benefit of and shall be binding
upon the successors and assigns of the Company.

Section XII. Amendment; Waiver.

      No amendment, modification, or discharge of this Agreement shall be valid
or binding unless set forth in writing and duly executed by each of the parties
hereto. Any waiver by any party or consent by any party to any breach of or any
variation from any provision of this Agreement shall be valid only if in writing
and only in the specific instance in which it is given, and such waiver or
consent shall not be construed as a waiver of any subsequent breach or any other
provision or as a consent with respect to any similar instance or circumstance.

Section XIII. Arbitration.

      Except as provided below, any disputes or claims of any kind or nature,
including as to arbitrability under this Agreement, between Employee and the
Company arising out of, related to, or in connection with any aspect of
Employee's employment with the Company or its termination, including all claims
arising out of this Agreement and claims for alleged discrimination, harassment,
or retaliation in violation of Title VII of the Civil Rights Act of 1964, the
Civil Rights Act of 1991, 42 U.S.C. ss. 1981, the Age Discrimination in
Employment Act of 1967, the Americans with Disabilities Act of 1990, the Family
and Medical Leave Act of 1993, the Fair Labor Standards Act, the Employee
Retirement Income Security Act of 1974, or any other federal, state, or local
law, shall be settled by final and binding arbitration in San Francisco,
California. Either party may file a written demand for arbitration with the
American Arbitration Association pursuant to its National Rules for the
Resolution of Employment Disputes. The arbitration shall be conducted by a
single neutral arbitrator who is a member of the Bar of the State of California,
has been actively engaged in the practice of law for at least fifteen (15)
years, and has substantial experience in connection with employment law and
interpretation of contracts. In considering the relevancy, materiality,
discoverability, and admissibility of evidence, the arbitrator shall take into
account, among other things, applicable principles of legal privilege, including
the attorney-client privilege, the work product doctrine, and appropriate
protection of the Company's Trade Secrets and Confidential Information. Upon the
request of either party, the arbitrator's award shall be written and include
findings of fact and conclusions of law. Judgment on the award rendered by the
arbitrator may be entered by any court having jurisdiction. Any arbitration of
any claim by Employee may not be joined or consolidated with any other
arbitration(s) by or against the Company, including through class arbitration.
The prevailing party in any such arbitration, or in any action to enforce this
Section XIII or any arbitration award hereunder, shall be entitled to recover
that party's attendant attorneys' fees and related expenses from the other party
to the maximum extent permitted by law. Except as may otherwise be required by
law for this Agreement to be enforceable, each party shall be responsible for
payment of one-half (1/2) of arbitration filing and administrative fees, and
one-half (1/2) of fees and expenses of the arbitrator, irrespective of the
outcome.

                        WRITTEN NOTIFICATION TO EMPLOYEE

      In accordance with California Labor Code Section 2872, you are hereby
notified that your Agreement on Confidentiality, Work Product, and
Nonsolicitation does not require you to assign to the Company any invention for
which no equipment, supplies, facility, or trade secret information of the
Company was used, that was developed entirely on your own time, that does not
relate to the business of the Company or to the Company's actual or demonstrably
anticipated research or development, and that does not result from any work
performed by you for the Company.

      The following is the text of California Labor Code Section 2870:

            (a) Any provision in an employment agreement which provides that an
            employee shall assign or offer to assign any of his or her rights in
            an invention to his or her employer shall not apply to an invention
            that the employee developed on his or her own time, without using
            the employer's equipment, supplies, facilities, or trade secret
            information except for those inventions that either:

                  (1) relate at the time of conception or reduction to practice
                  of the invention to the employer's business, or actual or
                  demonstrably anticipated research or development of the
                  employer, or

                  (2) result  from any work  performed  by the  employee
                  for the employer.

            (b) To the extent a provision in an employment agreement purports to
            require an employee to assign an invention otherwise excluded from
            being required to be signed under subdivision (1), the provision is
            against the public policy of this state and is unenforceable.

I hereby acknowledge receipt of this written notification.

      2. License Grant; Content Pages.

            2.1 Creation and Use. Adam grants to Licensee a non-exclusive,
      non-transferable, world-wide license to use and display the Adam
      proprietary content set forth on Exhibit 1 (the "Licensed Content") on the
      Licensee Web Site and other Web sites wholly owned and operated by
      Licensee subject to the terms and conditions of this Agreement. Licensee
      may not use, copy, modify, repackage, distribute or create derivative
      works from the Licensed Content in any manner not licensed by this
      Agreement.

            2.2 Development and Support.

                  (a) Adam will create and provide to Licensee in HTML format
            the Pediatric Illustrated Encyclopedia (the "Content Pages").

                  (b) Each Content Page will have at least one Adam icon with an
            appropriate Adam trademark or Adam Logo, as specified for appearance
            and placement according to Exhibit 2. During the Term, Licensee will
            identify Adam as the provider of the Pediatric Illustrated
            Encyclopedia and shall post the Adam Logo on the home page of the
            Licensee Web Site, which icon will include a link to the Content
            Pages.

                  (c) Adam will provide to Licensee access to the Health Images
            and Presentations. Licensee may select and use items from the Health
            Images and Presentations to annotate the content owned by Licensee
            and provided on the Licensee Web Site ("Licensee Content"). During
            the Term, Licensee will identify Adam as the provider of any portion
            of the Health Images and Presentations used by Licensee in the
            Licensee Content.

            2.3 Restrictions.

                  (a) Licensee may not use the Licensed Content, or authorize or
            permit any third person to use the Licensed Content, for any purpose
            other than those expressly authorized in this Section 2.

                  (b) Licensee may not re-license or distribute any portion of
            the Licensed Content to any third person other than as expressly
            authorized in this Section 2 or assign its rights in the Licensed
            Content to any third person except under a separate agreement
            between Adam and Licensee. Any sublicense or distribution of
            Licensee Content containing any Licensed Content will be subject to
            terms, including a royalty payable to Adam, of a reseller or
            distribution agreement between Adam and Licensee.

                  (c) Except as permitted by this Agreement, Licensee may not
            authorize any party to co-brand the Content Pages. For purposes of
            this Agreement, the terms "co-brand" or "co-branding" mean to
            display a name, logo, trademark, or other means of attribution or
            identification of any party in such a

                                       2

<PAGE>

            manner reasonably likely to give a User the impression that such
            other party has the right to display, publish, or distribute the
            Licensed Content.

                  (d) Licensee may modify the formatting, look and feel of the
            Licensed Content. Except as provided in the foregoing sentence,
            Licensee may not make any changes or modifications to the Licensed
            Content. Licensee may not translate the Licensed Content into any
            other language.

                  (e) Licensee may not authorize any party to link to, copy, or
            frame the Content Pages (whereby the Content Pages will appear on
            the same screen with a portion of another web site) or otherwise
            co-brand or re-package the Content Pages. Licensee will cause any
            unauthorized framing to cease immediately.

                  (f) Neither Party shall make any public statements or issue
            any press releases relating to this Agreement without the prior
            approval of the other Party. Adam may issue a press release
            announcing the signing of this Agreement and will obtain the prior
            approval of Licensee, which shall not be unreasonably withheld.

                  (g) Licensee may sell and serve advertising opportunities on
            the Content Pages without obligation to share revenues from such
            sales with Adam.

                  (h) Licensee will be required to incorporate the updates Adam
            provides to the Licensed Content on the Licensee Web Site within
            thirty (30) days of receipt of such updates. If Adam provides an
            update to Licensee for the Licensed Content, Licensee shall (a) use
            commercially reasonable efforts to incorporate the update on the
            Licensee Web Site and other Web sites wholly owned and operated by
            Licensee that are displaying the Licensed Content, (b) use
            commercially reasonable efforts to distribute such update to third
            parties to whom Licensee has distributed the Licensed Content at the
            earliest possible date, and (c) use reasonable efforts to request
            third parties to whom Licensee has distributed the Licensed Content
            to substitute and use such update at the earliest possible date.

      3. Logo License.

            3.1 Licensee. Licensee grants Adam a limited, non-exclusive,
      non-transferable license to use the Licensee logo and trademarks set forth
      on Exhibit 2 (the "Licensee Logo") solely in connection with (i) their
      display on Adam's standard marketing material, listing users and licensees
      of Adam's content and (ii) such other uses as Licensee may permit. Adam
      may not use, copy or display the Licensee Logo in any manner except as
      provided in this Agreement.

            3.2 Adam. Adam grants Licensee a limited, non-exclusive,
      non-transferable license to use the Adam logo set forth on Exhibit 2 (the
      "Adam Logo") solely (i) to the extent the Adam Logo is apparent on the
      Licensee Web Site, (ii) to the extent the Adam Logo is apparent on the
      Content Pages, (iii) to display on Licensee's standard marketing material,
      listing content providers and (iv) otherwise as required by this
      Agreement. Licensee may not use, copy or display the Adam Logo in any
      manner except as provided in this Agreement.

      4. Confidentiality.

            4.1 Confidential Information. Licensee and Adam agree to hold the
      terms and pricing of this Agreement confidential, except that both Adam
      and Licensee may disclose the fact that this Agreement exists for the
      Licensed Content, the Content Pages, and the Licensee Web Site, and both
      parties may disclose such pricing as necessary to comply with legal
      disclosure requirements (but will first use good faith efforts to obtain
      confidential treatment of pricing information in connection with any
      required filings or other disclosures). In addition, either party may
      disclose the terms and pricing of this Agreement to its affiliates, and to
      its business, financial, and legal representatives and consultants
      (provided such individuals owe a duty of confidentiality to the disclosing
      party) as necessary for such party to perform its obligations under this
      Agreement.

            4.2 Exceptions. The obligation of confidentiality in Section 4.1
      will not extend to documents or things which:

                  (a) are in or fall into the public domain through no fault of
            the receiving party;

                  (b) are publicly disclosed by the party owning any
            confidential information contained therein prior to any disclosure
            by the other party; or

                  (c) must be disclosed by legal or governmental action, rule or
            regulation.

      5. Ownership

            5.1 Adam. Except for the license rights provided in this Agreement,
      Adam retains ownership of, and all right, title and interest in and to:
      (a) the Adam Logo; (b) any trademark, trade name, patent, copyright,
      technology, trade secret or know-how affixed to, incorporated in or
      relating to the Licensed Content and (c) any Adam created or owned patent,
      copyright, technology, trade secret or know-how affixed to, incorporated
      into the Content Pages. Licensee will use good faith efforts to cooperate
      with Adam in the protection of Adam's intellectual property rights, at
      Adam's reasonable request. Licensee will not remove, alter or conceal any
      Adam proprietary notice displayed on the Licensed Content or the Content
      Pages, nor will Licensee authorize others to do so.

            5.2 Licensee. Except for the license rights provided in this
      Agreement, Licensee retains ownership of, and all right, title and
      interest in and to the Licensee Content and any trademark, trade name,
      patent, copyright, technology, trade secret or know-how affixed to,
      incorporated in or relating to the Licensee Web Site. Licensee is not
      acquiring any right, title or interest of any nature whatsoever in the
      Licensed Content, the Content Pages, or the Adam Logo except the license
      rights provided in this Agreement.

      6. Term and Termination

            6.1 Term. The term of this Agreement shall commence on the Effective
      Date and expire on the second anniversary of the Effective Date (the
      "Initial Term"), unless earlier terminated. The Term of this Agreement
      shall be automatically renewed for

                                       4
<PAGE>

      successive one (1) year terms (each a "Renewal Term") unless earlier
      terminated as provided herein or unless either party gives the other party
      written notice of its intent not to renew at least sixty (60) days prior
      to the end of the then-current term.

            6.2 Termination for Breach. Adam and Licensee each will have the
      right to terminate this Agreement upon written notice to the other party
      in the event that the other party commits a material breach of its
      warranties or obligations under this Agreement which has not been cured or
      corrected within 30 days following written notice given by the
      non-breaching party.

            6.3 Automatic Termination. This Agreement will terminate
      automatically if: (a) either party becomes the subject of any voluntary
      petition in bankruptcy or any voluntary proceeding relating to insolvency,
      receivership, liquidation or composition for the benefit of creditors; or
      (b) either party becomes the subject of an involuntary petition in
      bankruptcy or any involuntary proceeding relating to insolvency,
      receivership, liquidation or composition for the benefit of creditors, if
      such petition or proceeding is not dismissed within sixty (60) days of
      filing.

            6.4 Effect of Termination. Upon and after the termination of this
      Agreement for any reason upon any effective date of termination (the
      "Termination Date"):

                  (a) Licensee will immediately cease to display the Licensed
            Content and the Content Pages; and

                  (b) Within five (5) business days after the Termination Date,
            Licensee will either delete or return to Adam any copies it may have
            (in any form or format) of the Licensed Content and certify to Adam
            in writing that it has done so.

      7. Indemnification

            7.1 Licensee. Licensee will indemnify, defend and hold Adam harmless
      from any loss, damage or cost (including reasonable attorneys fees and
      court costs should Licensee breach its obligation to defend) arising out
      of any third-party claim relating to (i) the Licensee Web Site, (ii) the
      Licensee Content, (iii) any notices posted on, or changes made to, the
      Licensed Content or the Content Pages by Licensee, (iv) any claim,
      investigation or cause of action initiated by an U.S. governmental entity
      or regulatory agency arising out of the use of the Licensed Content or the
      Content Pages on the Licensee Web Site, or (v) any breach of this
      Agreement. Adam shall promptly notify Licensee of any such claim (unless
      the failure to notify Licensee promptly does not materially and adversely
      affect Licensee's ability to defend the claim), and shall permit Licensee
      to exercise sole control over the defense and settlement of such claim and
      shall cooperate with Licensee in the defense of the claim (at the expense
      of Licensee). Licensee will have the sole right to defend or settle any
      claim subject to indemnification by Licensee under this Section 7,
      provided that (i) counsel appointed by Licensee to defend Adam will not
      take any position which if sustained would cause Adam not to be
      indemnified by Licensee and (ii) Licensee may control the settlement of
      the action in its sole discretion so long as any such settlement imposes
      no obligations or liabilities on Adam. Adam will have the right to
      participate with Licensee in the defense or appeal of any such claim or
      judgment, at Adam's option and at Adam's own expense (such expense

                                       5

      not being indemnified by Licensee), but Licensee will have sole control

      appeal or similar action.

            7.2 Adam. Adam will indemnify, defend and hold Licensee harmless
      from any loss, damage or cost (including reasonable attorneys fees and
      court costs should Adam breach its obligation to defend) arising out of
      any third-party claim relating to the Licensed Content asserted against
      Licensee and based upon the assertion that the Licensed Content, in the
      form provided by Adam, infringes the U.S. copyright interests of such
      third party. Licensee shall promptly notify Adam of any such claim (unless
      the failure to notify Adam promptly does not materially and adversely
      affect Adam's ability to defend the claim), and shall permit Adam to
      exercise sole control over the defense and settlement of such claim and
      shall cooperate with Adam in the defense of the claim (at the expense of
      Adam). Adam will have the sole right to defend or settle any claim subject
      to indemnification by Adam under this Section 7, provided that (i) counsel
      appointed by Adam to defend Licensee will not take any position which if
      sustained would cause Licensee not to be indemnified by Adam and (ii) Adam
      may control the settlement of the action in its sole discretion so long as
      any such settlement imposes no obligations or liabilities on Licensee.
      Licensee will have the right to participate with Adam in the defense or
      appeal of any such claim or judgment, at Licensee's option and at
      Licensee's own expense (such expense not being indemnified by Adam), but
      Adam will have sole control and authority with respect to any such
      defense, compromise, settlement, appeal or similar action.

      8.1 Adam. Adam will indemnify, defend and hold Licensor harmless from any
loss, damage or cost (including reasonable attorneys fees and court costs should
Adam breach its obligation to defend) arising out of any third-party claim
relating to (i) any notices posted on, or changes made to, the Licensor Content

materially and adversely affect Adam's ability to defend the claim), and shall
permit Adam to exercise sole control over the defense and settlement of such
claim and shall cooperate with

                                      -5-
<PAGE>

Adam in the defense of the claim (at the expense of Adam). Adam will have the
sole right to defend or settle any claim subject to indemnification by Adam
under this Section 8, provided that (i) counsel appointed by Adam to defend
Licensor will not take any position which if sustained would cause Licensor not
to be indemnified by Adam and (ii) Adam may control the settlement of the action
in its sole discretion so long as any such settlement imposes no obligations or
liabilities on Licensor. Licensor will have the right to participate with Adam
in the defense or appeal of any such claim or judgment, at Licensor's option and
at Licensor's own expense (such expense not being indemnified by Adam), but Adam
will have sole control and authority with respect to any such defense,
compromise, settlement, appeal or similar action.

      8.2 Licensor. Licensor will indemnify, defend and hold Adam harmless from
any loss, damage or cost (including reasonable attorneys fees and court costs

claim relating to the Licensor Content asserted against Adam and based upon the
assertion that the Licensor Content, in the form provided by Licensor, infringes
the U.S. copyright interests of such third party. Adam shall promptly notify
Licensor of any such claim (unless the failure to notify Licensor promptly does
not materially and adversely affect Licensor's ability to defend the claim), and
shall permit Licensor to exercise sole control over the defense and settlement
of such claim and shall cooperate with Licensor in the defense of the claim (at
the expense of Licensor). Licensor will have the sole right to defend or settle
any claim subject to indemnification by Licensor under this Section 8, provided
that (i) counsel appointed by Licensor to defend Adam will not take any position
which if sustained would cause Adam not to be indemnified by Licensor and (ii)
Licensor may control the settlement of the action in its sole discretion so long
as any such settlement imposes no obligations or liabilities on Adam. Adam will
have the right to participate with Licensor in the defense or appeal of any such
claim or judgment, at Adam's option and at Adam's own expense (such expense not
being indemnified by Licensor), but Licensor will have sole control and
authority with respect to any such defense, compromise, settlement, appeal or
similar action.

relating to insolvency, receivership, liquidation or composition for the benefit
of creditors; or (b) either party becomes the subject of an involuntary petition
in bankruptcy or any involuntary proceeding relating to insolvency,
receivership, liquidation or composition for the benefit of creditors, if such
petition or proceeding is not dismissed within sixty (60) days of filing.

      9.4 Effect of Termination. Upon and after the termination of this
Agreement for any reason upon any effective date of termination (the
