               The type, timing and placement of these advertising placements
               shall be at Yahoo's reasonable discretion.

          4.2  Yahoo agrees to provide advertising placements promoting the
               Yahoo B2B Site on the front Page of Yahoo! Auctions and the front
               Page of Yahoo! Small Business. DoveBid's second payment under
               Section 9.1 will be due on the date that Yahoo places such
               promotions on those Yahoo Properties. Such date is referred to as

               Views of such Co-Branded Banners and Co-Branded Buttons will be
               mutually determined by the parties but will be equivalent to [*]
               in advertising value. The manner, timing and placement of such
               Co-Branded Banners and Co-Branded Buttons shall be determined by
               Yahoo and reasonably approved by DoveBid.

          4.4  Yahoo will provide Front Page Promotion to be scheduled on dates
               mutually agreed to by the parties. All Front Page Promotions are
               subject to availability and Yahoo standard terms for Front Page
               Promotions.

5.   Implementation of DoveBid Links.
     -------------------------------

          5.1  Yahoo will be solely responsible for the user interface and
               placement of the DoveBid Links on the Yahoo Properties, except
               that Yahoo agrees that the DoveBid Banner and DoveBid Button will
               appear in a manner substantially similar to the examples set
               forth in Exhibit J. DoveBid will be solely responsible for and
                        ---------

          5.2  Yahoo reserves the right, at any time, to redesign or modify: (i)
               the organization, structure, specifications, "look and feel,"
               navigation, guidelines and other elements of the Yahoo Properties
               on which a DoveBid Link is placed; or (ii) the Yahoo B2B Site and
               the layout of the DoveBid Content. If any such redesign or
               modification materially and adversely affects in any manner the
               nature of the distribution, promotions, and/or placements
               required under this Agreement (including without limitation any
               DoveBid Link or DoveBid Content), Yahoo will notify DoveBid and
               will work with DoveBid in good faith to provide DoveBid, as its
               sole remedy, with comparable distribution, promotions and/or
               placements on the Yahoo Properties which will be subject to
               DoveBid's reasonable approval.

               Deliverables"). All content and material contained in the DoveBid
               ------------
               Links are subject to Yahoo's approval (which shall not be
               unreasonably withheld) and must comply with all applicable
               federal, state and local laws, rules and regulations, including
               but not limited to consumer protection laws and rules and
               regulations governing product claims, truth in labeling and false
               advertising.

          5.4  In no event will the first Page on the DoveBid Site or on a
               DoveBid Subsidiary Site contain graphic or text links,
               advertisements or promotions of any Yahoo Competitors. This

               click through directly from any DoveBid Anchor Tenant Module,
               DoveBid Button, Yahoo Welcome or Yahoo Logout Button. DoveBid
               will also use its best efforts to include a Yahoo graphic link on
               any page to which users click through directly from any other
               DoveBid Link placed by Yahoo under this Agreement. The Yahoo
               graphic link will (a) be placed in a manner approved by Yahoo (b)
               contain the Yahoo name and logo as provided by Yahoo and (c)
               directly link the user back to a page designated by Yahoo.

          5.6  DoveBid will design and operate the DoveBid Site and each DoveBid
               Subsidiary Site to (a) handle [*] simultaneous requests; (b) have
               a minimum [*] uptime and maximum [*] downtime per calendar
               quarter of the Term (except for planned downtime that may be
               required for system enhancements, upgrades or preventative

               Site to the Yahoo Properties initiate within less than [*], on
               average, of request. DoveBid will provide customer service
               support for all inquiries regarding the services offered on the
               DoveBid Site. DoveBid will provide the following customer service
               information on the DoveBid Site in a manner mutually agreed to by
               the parties: (i) an email address and other contact information,
               and (ii) information/guidelines on DoveBid's policy regarding
               disputes. DoveBid agrees that: [*] of all customer care requests
               will receive responses within [*] hours. The criteria set forth
               in the preceding three sentences will be referred to hereinafter
               as the "DoveBid Performance Criteria".) Without limitation, if
                       ----------------------------
               DoveBid fails to meet any of the DoveBid Performance Criteria in
               any material respect, Yahoo will have the right to terminate the
               Agreement if DoveBid does not cure such failure

               payments accrued and not paid (including revenue share payments)
               through the date of termination).

               maximum [*] downtime per calendar quarter of the Term (except for

               any of the above criteria in any material respect, DoveBid will
               have the right to terminate the Agreement if Yahoo does not cure
               such failure within [*] days following written notice thereof to
               Yahoo. In the event of such termination, DoveBid will not be
               required to make any further payments to Yahoo (other than to

               --------
               non-exclusive, worldwide, fully paid license to use, reproduce
               and display the Yahoo Brand Features as described in Section 5.5
               above; provided, in all cases, that such use is in accordance

               manner substantially similar to the example set forth on Exhibit
               J. Notwithstanding the foregoing, Yahoo may, at any time and in
               its sole discretion remove or not display any DoveBid Content (a)
               for technical or service related issues, (b) if Yahoo reasonably
               believes that the DoveBid Content violates any of Yahoo's
               standards for acceptable listings (which for purposes of this
               Agreement will be deemed to be the "Sellers Rules" for listings

               notify DoveBid in writing in the event that it exercises its
               rights not to display or remove any DoveBid Content.

          6.4  As between DoveBid and Yahoo, DoveBid will retain all right,

          7.1  During the Term, Yahoo will place no more than [*] Anchor Tenant
               Modules promoting Business to Business Merchants on the front

               the category and subcategory Pages of the Yahoo B2B Site.

          7.2  DoveBid acknowledges and agrees that, except for the limited
               exclusivity provision of Section 7.1, Yahoo may place any
               advertising units for or otherwise promote any entity, including
               but not limited to other Business to Business Merchants, on any
               Page within the Yahoo Properties. Yahoo shall also not be

               apply to additional sites acquired by Yahoo and added to the
               Yahoo Properties to the extent that such additional sites had a
               preexisting [*] or co-branded banner or button relationship with
               [*] or [*].

8.   Page Views.
     ----------

          8.1  Yahoo expressly acknowledges its obligation under this Agreement
               to furnish DoveBid with advertising and other promotions valued
               in the aggregate at [*] based on a discount of [*] off of Yahoo's
               year 2000 advertising rate card. The parties acknowledge that
               based on the amount of such consideration to be paid by DoveBid,
               Yahoo will deliver a minimum of [*] Page Views with a preliminary
               target distribution of such Page Views as set forth below (the
               "Preliminary Targets"). Yahoo will use commercially reasonable
                -------------------
               efforts to deliver these Page Views as set forth below, but
               Yahoo's Page View obligation is with respect to the program as a
               whole. Yahoo will not be in breach of this Agreement for failure
               to deliver the specific number of Page Views in any of the
               following areas.

          .    [*] DoveBid Banner Pages

          .    [*] DoveBid Button Pages

          .    [*] DoveBid Email Messages

          .  [*] Page Views of Front Page Promotions

          .  [*] DoveBid Banner Advertisements placed on Run of Network

     Notwithstanding the foregoing, Yahoo expressly acknowledges that it is the
     intent and desire of the parties to mutually track the efficacy of the
     advertising and promotions to be provided by Yahoo hereunder and to make
     adjustments to the Preliminary Targets for the distribution and types of
     promotions in a manner consistent with the parties' overall business goals
     for this Agreement.  Accordingly, DoveBid will have the right, once each
     calendar month during the Term to request adjustments to the Preliminary
     Targets; provided that all adjusted "Preliminary Targets" (a) will be
     valued at [*] rates in [*] to the [*] available on [*]; (b) will not exceed
     a total value of [*]; (c) will be placed subject to availability and
     Yahoo's prior approval and on a schedule to be mutually agreed upon by the
     parties; and (d) are subject to the "make good" provisions set forth in
     Section 8.2 below.

          8.2  In the event that Yahoo fails to deliver the number of Page Views
               or emails set forth in Section 8.1 (as reduced by any proration
               under Section 8.3) before the expiration of the Term, Yahoo will
               "make good" the shortfall by extending its obligations under
               Sections 2 and 3 in the areas set forth therein (or similar
               inventory mutually agreed upon by the parties) beyond the end of
               the Term until such Page View obligation is satisfied. Yahoo will
               use commercially reasonable efforts to make good any undelivered
               Page Views or emails within three months (but in any event will
               "make good" the shortfall within six months) from the end of the
               Term. The provisions of this Section 8.2 set forth the entire
               liability of Yahoo, and DoveBid's sole remedy, for Yahoo's
               failure to meet its Page View obligation set forth in Section
               8.1.

          8.3  In the event that DoveBid fails to (a) provide Yahoo, at least
               [*] business day prior to the scheduled activation date of any
               DoveBid Link with the DoveBid Deliverables necessary for Yahoo to
               activate such DoveBid Link; or (b) design and operate the DoveBid
               Site or a DoveBid Subsidiary Site in accordance with Section 5.6,
               then (1) the number of Page Views set forth in Section 8.1 will
               be prorated on a daily basis until DoveBid remedies such failure
               (e.g., if Yahoo committed to deliver [*] Page Views over a one
               (1) year period and DoveBid provided Yahoo with the DoveBid
               Deliverables 15 days after the DoveBid Deliverables Due Date,
               then Yahoo's Page View obligation would be reduced by [*] Page
               Views) and (2) all payments made or due hereunder will be
               converted to a non-refundable, non-creditable holding fee for
               making the advertising inventory available to DoveBid.

          8.4  Yahoo will provide DoveBid with access to an electronic database,
               the accuracy of which is periodically reviewed and certified by
               Ernst & Young, LLP or a similarly reputable and independent
               entity, that describes Yahoo's calculation of the Page Views
               delivered during the Term.

9.   Compensation.
     ------------

          9.1  Slotting Fee.  In consideration of Yahoo's performance and
               ------------
               obligations as set forth herein, DoveBid will pay to Yahoo a non-
               refundable (except as expressly set forth in Section 10.3) non-
               creditable slotting fee equal to [*]. DoveBid will pay such fee
               to Yahoo on or before the dates set forth below, with the first
               payment of [*] designated as a set up fee for the design,
               consultation, development and implementation of the DoveBid
               Links.

          Payment                       Date
          -------                       ----

          [*]       upon execution of the Agreement, which shall be designated
                    as a set-up fee for the design, consultation, development
                    and implementation of the DoveBid Links;

          [*]       on the Second Payment Date; and

          [*]       for three quarterly payments payable in 90 day intervals;
                    with the first payment due 90 days after the Second Payment
                    Date.

          9.2  Revenue Share:  In addition to the compensation described above,
               --------------
               DoveBid will, each calendar quarter during the Term, purchase an
               additional amount of advertising in the form of Co-Branded
               Banners or Co-Branded Buttons in an amount equal to [*] of the
               Gross Commissions earned by DoveBid on all sales that originate
               from users that click-through from any DoveBid Link. "Gross
               Commissions" means the transaction fee amount that is collected
               by DoveBid or a DoveBid Subsidiary on auction or retail sales on
               the DoveBid Site or any DoveBid Subsidiary Site. If DoveBid owns
               the asset, then "Gross Commissions" means the imputed transaction
               fee that would have been collected by DoveBid if DoveBid had
               charged its standard commission rate on the value of the asset
               sold. Payments will be made quarterly by DoveBid to Yahoo within
               [*] days following the last day of each calendar quarter. DoveBid
               will provide to Yahoo quarterly reports certified by an officer
               of DoveBid that describes in sufficient detail the number of
               transactions completed, the gross revenue resulting from those
               transactions, and the calculation of the Gross Commission. Yahoo
               will provide Page Views of Co-Branded Buttons or Co-Branded
               Banners in accordance with Yahoo's standard advertising rates in
               effect at the time.

          9.3  Audit Rights.  DoveBid will maintain materially complete and
               ------------
               accurate records in accordance with generally accepted methods of
               accounting for revenue share transactions described in Section
               9.2 above and will allow Yahoo, at its own expense, to direct an
               independent certified public

               accounting firm to inspect and audit such records during normal
               business hours with written notice to DoveBid. Such inspections
               and audits will be limited to one time in any twelve (12) month
               period and all of DoveBid's records (and any other information
               disclosed by DoveBid in connection with such audit) will be
               deemed to be DoveBid Confidential Information, subject to the
               terms and conditions of Section 11.3 hereof. In the event that
               any audit reveals an underpayment of more than ten percent (10%),
               DoveBid will pay the reasonable cost of such audit.

          9.4  Payment Information.  Except as otherwise expressly set forth
               -------------------
               in this Agreement, all payments herein are non-refundable and
               non-creditable and will be made by DoveBid via wire transfer into
               Yahoo's main account according to the wire transfer instructions
               set forth in Exhibit F.
                            ---------

          9.5  Late Payments.  Any portion of the above payments that has not
               -------------
               been paid to Yahoo on the dates set forth above will bear
               interest at the greater of (a) 1% per month or (b) the maximum
               amount allowed by law. Notwithstanding the foregoing, any failure
               by DoveBid to make the payments specified in Sections 9.1 and 9.2
               on the dates set forth therein constitutes a material breach of
               this Agreement.

          9.6  Warrant.  DoveBid will issue to Yahoo a Warrant in the form
               -------
               attached hereto as Exhibit I on the Effective Date of this
                                  ---------
               Agreement.

10.  Term and Termination.
     --------------------

          10.1 Term.  This Agreement will commence upon the Effective Date and,
               ----
               unless terminated as provided herein, will remain in effect for
               the Term.

          10.2 Right of [*].  In the event that Yahoo, in its sole discretion,
               ------------
               elects to [*] advertising and promotion program described in this
               Agreement [*], Yahoo will provide written notice to DoveBid at
               least [*] days [*] to the [*]. Yahoo will describe its reasonable
               [*] for such [*] in its written notice to DoveBid. If DoveBid
               declines to commence [*] with Yahoo regarding such [*] within [*]
               days after receiving such written notice from Yahoo, or if the
               parties fail to reach agreement within [*] days following the
               commencement of [*], or such later date as is agreed by the
               parties, Yahoo may [*] to [*]

          10.3 Termination by DoveBid.  If the Yahoo B2B Site does not launch
               ----------------------
               by [*], then DoveBid will have the right to terminate the
               Agreement with thirty (30) days written notice to Yahoo (unless
               the Yahoo B2B Site launches within the thirty (30) day notice
               period). In the event of such termination by DoveBid, DoveBid
               will receive a pro-rata refund of the initial [*] payment less
               the value of the advertising placed by Yahoo promoting the
               DoveBid Site (or a DoveBid Subsidiary Site) delivered prior to
               the date of termination. The value of the advertising will be
               determined by Yahoo's

               current advertising rate card. Upon the effective date of such a
               termination by DoveBid, the Warrant described in Section 9.6 will
               be cancelled if it has not already been exercised by Yahoo.
               DoveBid agrees that except for the foregoing right to terminate
               and obtain a pro-rata refund, Yahoo will not be liable for any
               failure or delay to launch the Yahoo B2B Site. Notwithstanding
               the foregoing, DoveBid will not have the right to terminate or
               receive a pro-rata refund of any amounts paid if the Launch Date
               is delayed by any failure of DoveBid including, without
               limitation, any failure or delay in providing Yahoo with any of
               the DoveBid Deliverables. In the event of any failure or delay on
               the part of DoveBid, the Launch Date will be deemed to be the
               date that the Yahoo B2B Site is otherwise functional and
               available to the public.

               In addition, in the event that the Launch Date does not occur by
               [*] and DoveBid does not exercise its right to terminate the
               Agreement as described in Section 10.3 above, then the parties
               will discuss and mutually agree upon a revised compensation
               schedule to include payment to Yahoo for the advertising
               placements.  If the parties cannot mutually agree upon a revised
               compensation schedule, then Yahoo will have the right to
               terminate the Agreement without further obligation or liability
               to DoveBid.

          10.4 Termination by Either Party with Cause.  This Agreement may be
               --------------------------------------
               terminated at any time by either party (a) immediately upon
               written notice if the other party (1) becomes insolvent; (2)
               files a petition in bankruptcy; or (3) makes an assignment for
               the benefit of its creditors; or (b) 30 days after written notice
               to the other party of such other party's breach of any of its
               obligations under this Agreement in any material respect (10 days
               in the case of a failure to pay), which breach is not remedied
               within such notice period.

          10.5 Survival.  The provisions of Sections 1, 6.4, 8.2, 11, 12, 13,
               --------
               15 and this 10.5 will survive expiration or termination of this
               Agreement, except that DoveBid's payment obligations set forth in
               Section 9 will not survive a proper termination of this Agreement
               by DoveBid in accordance with Sections 10.3 or 10.4.

               the body or tribunal to which disclosure is being made or
               otherwise be held in the strictest confidence to the fullest

               other applicable governing body. Upon execution of this
               Agreement, DoveBid will provide Yahoo with its proposed
               redactions of this Agreement to be disclosed as part of its S-1
               filing. Notwithstanding the provisions of subsection (a) above,
               Yahoo will have 3 days prior to the date of the disclosure of the
               S-1.

          11.2 Publicity.  Any and all publicity relating to this Agreement and
               ---------
               subsequent transactions between Yahoo and DoveBid and the method
               of its release will be approved in advance of the release, in
               writing, by both Yahoo and DoveBid.

          11.3 Nondisclosure Agreement.  Yahoo and DoveBid acknowledge and
               -----------------------
               agree that the terms of the Mutual Nondisclosure Agreement
               attached hereto as Exhibit H will be incorporated by reference
                                  ---------
               and made a part of this Agreement, and will govern the use and
               disclosure of confidential information and all discussions
               pertaining to or leading to this Agreement.

          11.4 User Data.  All information and data provided to Yahoo by users
               ---------
               of the Yahoo Properties or otherwise collected by Yahoo relating
               to user activity on the Yahoo Properties will be retained by and
               owned solely by Yahoo. All information and data provided to
               DoveBid on the DoveBid Site or DoveBid Subsidiary Site otherwise
               collected by DoveBid relating to user activity on the DoveBid
               Site or DoveBid Subsidiary Site will be retained by and owned
               solely by DoveBid. Each party agrees to use information and data
               provided to it by a user only as disclosed to and authorized by
               that user and will not disclose, sell, license or otherwise
               transfer this information to any third party or use this
               information for the transmission of "junk mail," "spam" or any
               other unsolicited mass distribution of information.

               information provided by users of the DoveBid Site is maintained,
               accessed and transmitted in a secure environment and in

               of user data on those Pages of the DoveBid Site where the user is

               DoveBid represents and warrants that it has reviewed the FTC
               Order and will not engage in any conduct that would cause Yahoo
               to violate the FTC Order. DoveBid agrees to follow and comply
               with all

               reasonable instructions and directions of Yahoo to ensure Yahoo's
               compliance with the FTC Order.

12.  Indemnification.
     ---------------

          12.1 By DoveBid.  DoveBid, at its own expense, will indemnify,
               ----------
               defend and hold harmless Yahoo and its employees,
               representatives, agents and affiliates from and against any
               claim, demand, action or other proceeding brought by any third
               party against Yahoo to the extent that such claim, demand, action
               or other proceeding is based on, or arises out of a claim that
               any DoveBid Content, DoveBid Brand Feature, any material, product
               or service produced, distributed, offered or sold by DoveBid, or
               any material presented on the DoveBid Site or a DoveBid
               Subsidiary Site (1) infringes in any manner any copyright,
               patent, trademark, trade secret or any other intellectual
               property right of any third party; (2) is or contains any
               material or information that is obscene, defamatory, libelous,
               slanderous or that violates any law or regulation; (3) violates
               any rights of any person or entity, including but not limited to
               rights of publicity, privacy or personality; (4) has resulted in
               any consumer fraud, product liability, tort, breach of contract,
               injury, damage or harm of any kind to any third party; or (5) is
               subject to any fees, royalties, licenses or any other payments to
               any third party; provided, however, that in any such case (A)
               Yahoo provides DoveBid with prompt notice of any such claim; (B)
               Yahoo permits DoveBid to assume and control the defense of such
               action upon DoveBid's written notice to Yahoo of its intention to
               indemnify; and (C) upon DoveBid's written request, and at no
               expense to Yahoo, Yahoo will provide to DoveBid all available
               information and assistance reasonably necessary for DoveBid to
               defend such claim. DoveBid will not enter into any settlement or
               compromise of any such claim, which settlement or compromise
               would result in any liability to Yahoo, without Yahoo's prior
               written consent, which will not unreasonably be withheld. DoveBid
               will pay any and all costs, damages, and expenses, including, but
               not limited to, reasonable attorneys' fees and costs awarded
               against or otherwise incurred by Yahoo in connection with or
               arising from any such claim, suit, action or proceeding.

          12.2 By Yahoo.  Yahoo, at its own expense, will indemnify, defend and
               --------
               hold harmless DoveBid and its employees, representatives, agents
               and affiliates from and against any claim, demand, action or
               other proceeding brought by any third party against DoveBid to
               the extent that such claim, demand, action or other proceeding is
               based on, or arises out of, a claim that any Yahoo Brand Feature
               (1) infringes in any manner any copyright, patent, trademark,
               trade secret or any other intellectual property right of any
               third party or (2) is subject to any fees, royalties, licenses or
               any other payments to any third party; provided, however, that in
               any such case (1) DoveBid provides Yahoo with prompt written
               notice of any such claim; (2) DoveBid permits Yahoo to assume and
               control the defense of such

               action or proceeding upon Yahoo's written notice to DoveBid of
               its intention to indemnify; and (3) upon Yahoo's written request,
               and at no expense to DoveBid, DoveBid will provide Yahoo with all
               available information and assistance reasonably necessary for
               Yahoo to defend such claim. Yahoo will not enter into any
               settlement or compromise of any such claim, which settlement or
               compromise would result in any liability to DoveBid, without
               DoveBid's prior written consent, which will not be unreasonably
               withheld. Yahoo will pay any and all costs, damages and expenses,
               including but not limited to reasonable attorneys' fees and costs
               awarded against or otherwise incurred by DoveBid in connection
               with or arising from any such claim, demand, action or other
               proceeding.

     -----------------------

          EXCEPT AS PROVIDED IN SECTION 12, UNDER NO CIRCUMSTANCES WILL DOVEBID,
          YAHOO OR ANY AFFILIATE OF EITHER PARTY BE LIABLE TO THE OTHER PARTY
          FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR EXEMPLARY DAMAGES
          ARISING FROM THIS AGREEMENT, INCLUDING BUT NOT LIMITED TO LOSS OF
          REVENUE OR ANTICIPATED PROFITS OR LOST BUSINESS, EVEN IF THAT PARTY
          HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

14.  Insurance.
     ---------

          14.1 General Commercial Liability.  DoveBid will maintain insurance
               ----------------------------

               Yahoo and with coverage for commercial general liability and
               errors and omissions of at least [*] dollars per occurrence.
               DoveBid will name Yahoo as an additional insured on such
               insurance and will provide evidence of such insurance to Yahoo
               within 10 days after the Effective Date. Such insurance policy
               will not be cancelled or modified in a manner inconsistent with
               this provision without Yahoo's prior written consent. Yahoo will
               maintain insurance during the Term with a carrier that is
               reasonably acceptable to DoveBid and with coverage for commercial
               general liability and errors and omissions of at least $1 million
               dollars per occurrence.

15.  General Provisions.

          15.1 Independent Contractors.  It is the intention of Yahoo and
               -----------------------

               independent contractors with respect to the subject matter of
               this Agreement, and nothing contained in this Agreement will be
               deemed or construed in any manner whatsoever as creating any
               partnership, joint venture, employment, agency, fiduciary or
               other similar relationship between Yahoo and DoveBid.

               --------------------

               and signed by both parties. The waiver by any party of any breach
               or default will not constitute a waiver of any different or
               subsequent breach or default.

          15.4 Governing Law.  This Agreement will be governed by and
               -------------

               consent of the other party, which will not unreasonably be
               withheld or delayed. Notwithstanding the foregoing, either party
               may assign this Agreement to an entity that acquires
               substantially all of the stock or assets of a party to this
               Agreement, except that consent will be required in the event that
               the non-assigning party reasonably determines that the assignee
               will not have sufficient capital or assets to perform its
               obligations hereunder, or that the assignee is a direct
               competitor of the non-assigning party. All terms and provisions
               of this Agreement will be binding upon and inure to the benefit

               perform or delay in performing any obligation (other than the
               payment of money) under this Agreement if such failure or delay
               is due to fire, flood, earthquake, strike, war (declared or
               undeclared), embargo, blockade, legal prohibition, governmental
               action, riot, insurrection, damage, destruction or any other
               similar cause beyond the control of such party. If such event
               continues for more than 30 days, the other party may terminate
               this Agreement without further obligation.

consideration and which, if issued by the Commission, would charge respondent

thereafter executed an agreement containing a consent order, an admission by the
respondent of all the jurisdictional facts set forth in the aforesaid draft of

has been violated as alleged in such complaint, or that the facts as alleged in
such complaint, other than jurisdictional facts, are true and waivers and other

The Commission having considered the matter and having determined that it had
reason to believe that the respondent has violated the said Act, and that

has actual knowledge that such child does not have his or her parent's
permission to provide the information to respondent. Respondent shall not be
deemed to have actual knowledge if the child has falsely represented that (s)he
is not a child and respondent does not knowingly possess information that such
representation is false.

                                      IV.

IT IS FURTHER ORDERED that respondent, directly or through any corporation,
subsidiary, division, or other device, in connection with the online collection
of personal identifying information, in or affecting commerce, shall provide
clear and prominent notice to consumers, including the parents of children, with
respect to respondent's practices with regard to its collection and use of
personal identifying information. Such notice shall include, but is not limited
to, disclosure of:

     A. what information is being collected (e.g., "name," "home address," "e-
     mail address," "age," "interests");

     B. its intended use(s);

     C. the third parties to whom it will be disclosed (e.g., "advertisers of
     consumer products," mailing list companies," "the general public");

     D. the consumer's ability to obtain access to or directly access such
     information and the means by which (s)he may do so;

     E. the consumer's ability to remove directly or have the information
     removed from respondent's databases and the means by which (s)he may do so;
     and

     F. the procedures to delete personal identifying information from
     respondent's databases and any limitations related to such deletion.

<PAGE>

     Such notice shall appear on the home page of respondent's Web site(s) and
     at each location on the site(s) at which such information is collected.

Provided that, respondent shall not be required to include the notice at the
--------------
locations at which information is collected if such information is limited to
tracking information and the collection of such information is described in the
notice required by this Part.

Provided further that, for purposes of this Part, compliance with all of the
---------------------
following shall be deemed adequate notice: (a) placement of a clear and
prominent hyperlink or button labeled PRIVACY NOTICE on the home page(s), which
directly links to the privacy notice screen(s); (b) placement of the information
required in this Part clearly and prominently on the privacy notice screen(s),
followed on the same screen(s) with a button that must be clicked on to make it
disappear; and (c) at each location on the site at which any personal
identifying information is collected, placement of a clear and prominent
hyperlink on the initial screen on which the collection takes place, which links
directly to the privacy notice and which is accompanied by the following
statement in bold typeface:

NOTICE: We collect personal information on this site. To learn more about how we
use your information click here.

                                      V.

IT IS FURTHER ORDERED that respondent, directly or through any corporation,
subsidiary, division, or other device, in connection with the online collection
of personal identifying information from children, in or affecting commerce,
shall maintain a procedure by which it obtains express parental consent prior to
collecting and using such information.

Provided that, respondent may implement the following screening procedure that
-------------
shall be deemed to be in compliance with this Part. Respondent shall collect and
retain certain personal identifying information from a child, including birth
date and the child's and parent's e-mail addresses (hereafter "screening
information"), enabling respondent to identify the site visitor as a child and
to block the child's attempt to register with respondent without express
parental consent. If respondent elects to have the child register with it,
respondent shall: (1) give notice to the child to have his/her parent provide
express parental consent to register; and/or (2) send a notice to the parent's
e-mail address for the purpose of obtaining express parental consent. The notice
to the child or parent shall provide instructions for the parent to: (1) go to a
specific URL on the Web site to receive information on respondent's practices
regarding its collection and use of personal identifying information from
children and (2) provide express parental consent for the collection and use of
such information. Respondent's collection of screening information shall be by a
manner that discourages children from providing personal identifying information
in addition to the screening information. All personal identifying information
collected from a child shall be held by respondent in a secure manner and shall
not be used in any manner other than to effectuate the notice to the child or
parent, or to block the child from further attempts to register or otherwise
provide personal identifying information to respondent without express parental
consent. The personal identifying information collected shall not be disclosed
to any third party prior to the receipt of express parental consent. If express
parental consent is not received by twenty (20) days after respondent's
collection of the information from the child, respondent shall remove all such
personal identifying information from its databases, except such screening
information necessary to block the child from further attempts to register or
otherwise provide personal identifying information to respondent without express
parental consent.

                                      VI.

Nothing in this order shall prohibit respondent from collecting personal
identifying information from children or from using such information, as
specifically permitted in the Children's Online Privacy Protection Act of 1998
(without regard to the effective date of the Act) or as such Act may hereafter
be amended; regulations or guides promulgated by the Commission; or self-
regulatory guidelines approved by the Commission pursuant to the Act.

                                     VII.

IT IS FURTHER ORDERED that respondent GeoCities, and its successors and assigns,

information collected and retained by respondent and/or disclosed to third
parties, prior to the date of service of this order, as follows:

     A. Respondent shall provide a clear and prominent notice to each consumer
     over the age of twelve (12) from whom it collected personal identifying
     information and disclosed that information to CMG Information Services,
     Inc., describing such consumer's options as stated in Part VI.C and the
     manner in which (s)he may exercise them.

     B. Respondent shall provide a clear and prominent notice to the parent of
     each child from whom it collected personal identifying information prior to
     May 20, 1998, describing the parent's options as stated in Part VI.C and
     the manner in which (s)he may exercise them.

     C. Respondent shall provide the notice within thirty (30) days after the
     date of service of this order by e-mail, postal mail, or facsimile. Notice
     to the parent of a child may be to the e-mail address of the parent and, if
     not known by respondent, to the e-mail address of the child. The notice
     shall include the following information:

          1. the information that was collected (e.g., "name," "home address,"
          "e-mail address," "age," "interests"); its use(s) and/or intended
          use(s); and the third parties to whom it was or will be disclosed
          (e.g., "advertisers of consumer products," "mailing list companies,"
          "the general public") and with respect to children, that the child's
          personal identifying information may have been made public through
          various means, such as by publicly posting on the child's personal
          home page or disclosure by the child through the use of an e-mail
          account;

          2. the consumer's and childs parents right to obtain access to such
          information and the means by which (s)he may do so;

          3. the consumer's and childs parent's right to have the information
          removed from respondent's or a third party's databases and the means
          by which (s)he may do so;

          4. a statement that childrens information will not be disclosed to
          third parties, including public posting, without express parental
          consent to the disclosure or public posting;

          5. the means by which express parental consent may be communicated to
          the respondent permitting disclosure to third parties of a child's
          information; and

          6. a statement that the failure of a consumer over the age of twelve
          (12) to request removal of the information from respondent's databases
          will be deemed as

          approval to its continued retention and/or disclosure to third parties
          by respondent.

     D. Respondent shall provide to consumers, including the parents of
     children, a reasonable and secure means to request access to or directly
     access their or their childrens personal identifying information. Such
     means may include direct access through password protected personal
     profile, return e-mail bearing an electronically verifiable signature,

     third party's databases or an assurance that such information has been
     removed. Such means may include e-mail, postal mail, or facsimile.

     F. The failure of a consumer over the age of twelve (12) to request the
     actions specified above within twenty (20) days after his/her receipt of
     the notice required in Part VI.A shall be deemed to be consent to the
     information's continued retention and use by respondent and any third
     party.

     G. Respondent shall provide to the parent of a child a reasonable means to
     communicate express parental consent to the retention and/or disclosure to
     third parties of his/her child's personal identifying information.
     Respondent shall not use any such information or disclose it to any third
     party unless and until it receives express parental consent.

     H. If, in response to the notice required in Part VI.A, respondent has
     received a request by a consumer over the age of twelve (12) that
     respondent should remove from its databases the consumer's personal
     identifying information or has not received the express consent of a parent
     of a child to the continued retention and/or disclosure to third parties of
     a child's personal identifying information by respondent within twenty (20)
     days after the parent's receipt of the notice required in Part VI.B,
     respondent shall within ten (10) days:

          1. Discontinue its retention and/or disclosure to third parties of
          such information, including but not limited to (a) removing from its
          databases all such information, (b) removing all personal home pages
          created by the child, and (c) terminating all e-mail accounts for the
          child; and

          2. Contact all third parties to whom respondent has disclosed the
          information, requesting that they discontinue using or disclosing that
          information to other third parties, and remove the information from
          their databases.

          With respect to any consumer over the age of twelve (12) or any parent
          of a child who has consented to respondent's continued retention and
          use of personal identifying information pursuant to this Part, such
          consumer's or parent's continuing right to obtain access to his/her or
          a child's personal identifying information or removal of such
          information from respondent's databases shall be as specified in the
          notice required by Part IV of this order.

     protective legal treatment for such Confidential Information).

5.   Each of the parties agrees that it shall treat all Confidential Information
     of the other party with the same degree of care as it accords to its own
