           *** to ***                            ***%
           *** to ***                            ***%
           *** to ***                            ***%
           greater than ***                      ***%
</TABLE>

     b.   Calculation of Incentive Payment. The following steps shall be used by
          --------------------------------
Excite when calculating the Incentive Payment due SmartAge pursuant to Section
2.7 (a) herein, on a monthly basis:

          (1)  Determine the *** of SmartAge *** on the *** day of the ***
calendar month.

          (2)  Determine the *** of EAN Advertising Revenues per the ***
corresponding to the *** month's number of SmartAge ***.

          (3)  Determine the total EAN Advertising Revenues generated during the
*** month.

          (4)  *** the *** EAN Advertising Revenues by the *** of EAN
Advertising Revenues derived using the ***. The *** is the Incentive Payment due
SmartAge for *** month.

     For example, if there are *** SmartAge *** in the *** month, then the
percentage of EAN Advertising Revenues per the Incentive Schedule payable to
SmartAge is ***%. Therefore, if Excite generates $*** in EAN Advertising
Revenues, then the Incentive Payment that Excite shall pay SmartAge for the
given month is ***% of this amount, or $***.

     c.   Reporting.  SmartAge agrees to provide Excite on a monthly basis the
          ---------

     a.   Each party to this Agreement acknowledges that it may receive
confidential information ("Confidential Information") of the other party. For
purposes of this Agreement, Confidential Information shall mean any trade
secret, information, process, technique, algorithm, computer program (source and
object codes), design, drawing, formula, test data, business development and
marketing plans and concepts, records and files, financial data and budgetary
information, income or sales data or projections, customer lists, information
regarding customers, facilities, suppliers, plans, or market analysis.

reveal, divulge, or make known to any person, firm, corporation, or other entity
any Confidential Information of the other party; (2) it will not publish,
communicate, divulge, disclose or use such information for any purpose not
authorized by the other party, nor make copies or disclose in any manner
Confidential Information to any third party without prior written consent of the
other party; (3) it will not use the Confidential Information of the other party
for any purpose except to the extent required to accomplish the intent of this
Agreement; and (4) it will return to any documents (including copies, if any)

information has expired, or upon the request of the other party, and in any
event, upon completion or termination of this Agreement.

great as the precautions it takes to protect its own trade secrets, with respect
to the Confidential Information which it receives and shall disclose

manner consistent with all the obligations of this Agreement.

right and without restriction on disclosure; or (iv) is the subject of written
permission to disclose provided by the other party.

disclosing party shall be entitled to equitable relief, including injunction, in

form of action, whether in contract, tort (including without limitation
negligence), or otherwise.

INCIDENTAL, CONSEQUENTIAL, SPECIAL OR EXEMPLARY DAMAGES (EVEN IF SUCH DAMAGES
ARE FORESEEABLE, AND WHETHER OR NOT EXCITE HAS BEEN ADVISED OF THE POSSIBILITY
OF SUCH DAMAGES) ARISING FROM ANY ASPECT OF THE ADVERTISING RELATIONSHIP
PROVIDED FOR HEREIN. EXCITE SHALL IN NO EVENT BE LIABLE TO ADVERTISER FOR MORE
THAN THE TOTAL AMOUNT PAID TO EXCITE BY ADVERTISER HEREUNDER. EXCITE MAKES NO
REPRESENTATIONS, AND HEREBY EXPRESSLY DISCLAIMS ALL WARRANTIES, EXPRESS OR
IMPLIED, REGARDING EXCITE'S SERVICES OR ANY PORTION THEREOF, INCLUDING ANY

ANY WARRANTY REGARDING (I) THE NUMBER OF PERSONS WHO WILL ACCESS THE BANNER AND
(II) ANY BENEFIT ADVERTISER MIGHT OBTAIN FROM INCLUDING THE BANNER WITHIN
EXCITE'S WEB SITE.

Advertiser is solely responsible for any legal liability arising out of or
relating to (1) the Banner and/or (2) the Advertiser Web Content. Advertiser
represents and warrants that the Banner complies with Excite's advertising
standards; and that Advertiser holds the necessary rights to permit the use of
the Banner by Excite for the purpose of this Agreement; and that the use,
reproduction, distribution, or transmission of the Banner will not violate any
criminal laws or any rights of any third parties, including, but not limited to,

Excite reserves the right to reject any advertising which is not consistent with
Excite's standards. In addition, Excite shall have the right, at any time, to
remove any of Advertiser's advertising if Excite determines, in its sole
discretion, that the Banner, Advertiser Web Content or any portion thereof (i)
violates Excite's then applicable advertising policy, or (ii) is otherwise
objectionable to Excite, in which event Excite shall refund to Advertiser a pro
rata portion of the fee which Advertiser has paid to Excite for display of the
Banner (if Advertiser has paid Excite a flat fee).

Excite and Advertiser are independent contractors, and neither Excite nor
Advertiser is an agent, representative or partner of the other. Excite may
terminate this Agreement at any time in the event of material breach of this
Agreement by Advertiser. This Agreement sets forth the entire agreement between
Advertiser and Excite, and supersedes any and all prior agreements (whether
written or oral) of Excite and Advertiser with respect to the subject matter set
forth herein; provided, however, that all pricing will be governed by Excite's
then-current price list, whether in print or electronic form. This Agreement may
only be modified, or any rights under it waived, by a written document executed
by both parties. This Agreement shall be interpreted, construed and enforced in
all respects in accordance with laws of the State of California, without regard
to the actual state or country of incorporation or residence of Advertiser.
Advertiser hereby irrevocably consents to the exclusive jurisdiction of the
courts of the State of California and the federal courts situated in the State

By joining the SmartClicks ad network, members have indicated agreement to the
following terms and conditions. Compliance with the terms and conditions ensures
that only appropriate sites become SmartClicks members and that all network
advertising meets SmartClicks standards.

Any account or member violating these terms will be immediately removed from the
SmartClicks ad network.

1. SmartClicks reserves the right to refuse to continue membership to any Web
site in the SmartClicks network that contains or has links to nudity, sexual
situations, pornography, hate groups, illegal activities, offensive material or
for any other reason.

2. SmartClicks reserves the right to refuse to continue membership to any Web
site deemed to be competition, including, but not limited to, other banner
exchange services.

3. SmartClicks reserves the right to reject any banner that contains nudity,
profanity, offensive material or for any other reason.

4. Members agree to insert the provided SmartClicks HTML code for displaying
banners on their Web site. The SmartClicks HTML code may not be modified in any
way without written permission from SmartClicks.

5. Only one (1) SmartClicks banner may be placed on a page. A page is what is
displayed on one screen, so members who use frames must count all individual
pages in the frame as one page for banner placement purposes.

6. SmartClicks ad network banners must be displayed on the page such that the
banner is easily visible. Banners may not be "hidden" so that a visitor has no
way to view the banner.

7. SmartClicks banners must remain static on the member's Web site, and may not
be rotated with those of any other banner exchange service.

8. A member may not artificially inflate traffic counts to his/her site using
any device, program, robot or other means. A banner may not be placed on a page
that reloads automatically. Banners loaded via the SmartClicks HTML may not be
placed in newsgroups, e-mail, chat rooms or guestbooks, unless permission is
granted from SmartClicks. Any member whose account is terminated for
artificially inflated traffic counts may offer a defense to have the account re-
instated. SmartClicks' logs and/or judgments in these matters will prevail.

9. A member may not display the SmartClicks HTML on sites other than the one to
which the account is addressed to click through to, unless written permission is
granted from SmartClicks. A member may display the SmartClicks HTML on any of
the pages on the site, as long as there is a path of links from the page that
the banner clicks through to, to the page on which the banner is displayed.

10. A banner that appears on a member site may at any time be a banner for
another member, for a sponsor or partner, for SmartClicks or for other SmartAge
services. Ratings restrictions apply.

11. SmartClicks reserves the right not to accept any advertisements from
entities whose product or advertisement are deemed by SmartClicks to be
inappropriate, or for any other reason.

12. Members may cancel their accounts with the SmartClicks ad network at any
time by sending a request for cancellation, containing the account number and
password of the account in question, via e-mail to accounts@smartclicks.com, and
removing the SmartClicks HTML code from the Web site. Cancellations take place
immediately.

13. The SmartClicks name, logo, software, databases, reports, Web site and
information are proprietary and cannot be used without permission from
SmartClicks. Exception: each member has the right to use information compiled by
SmartClicks for the member's site or in the promotion of the member's site.

14. Members agree that their Web site information (name, URL, traffic counts,
etc.) may be used by SmartClicks, provided however, that it is the intent of
SmartAge to be consistent with the then current TrustE guidelines as of the
Effective Date.

15. The information members provide to SmartClicks will be kept confidential and
will not be distributed, except in aggregate, to any outside agency, without the
permission of the member, provided however, that it is the intent of SmartAge to
be consistent with the then current TrustE guidelines as of the Effective Date.

16. SmartClicks, its administrators, partners and sponsors cannot be held liable
for any damage or loss of information that may occur from the use of
SmartClicks' services.

17. Members agree to use SmartClicks at their own risk.

18. SmartClicks makes every effort to verify and maintain a high standard of
service quality, but SmartClicks does not make any guarantees regarding the
dependability or accuracy of SmartClicks' services.

19. SmartClicks will attempt to correct inconsistencies in credits due any
member based on the member's proof of inconsistency.

20. SmartClicks reserves the right to modify or change these Terms and
Conditions at any time, as it deems necessary. It is the member's responsibility
to keep current with changes in the Terms and Conditions, since changes are
effective for all members, regardless of when the member joined. Updates will be
evident by the date modified on the home page.

                                                                               4
<PAGE>

specific Member Data as determined by SmartAge, subject to reasonable approval
of Globe. The Registration Page(s) shall be served from a location as solely

parties such that during the term of this Agreement, the Member Data shall be
treated as Confidential Information (as defined in Section 9) of both parties.
Each party shall each be permitted to use Member Data for marketing and other

identifies (or permits the identification of) the origin of the Member Data as

6.   ALLOCATED IMPRESSIONS.

     6.1  Traffic Sharing. SmartAge agrees that the number of Impressions
          ---------------
allocated to Globe shall be calculated as a percentage of the total Available
Impressions generated by the Globe Network. This percentage shall be based upon
the number of Globe Members participating in the Banner Exchange Service per the
following schedule:

             Globe Members          % of Available Impressions
             -------------          --------------------------

          Up to *** members                     ***%
          ***-*** members                       ***%
          Over *** members                      ***%

For example, if there are 10,000 Globe Members in the Globe Network which each
on average generate 50 Impressions per day, then the total number of Available
Impressions per day in the Globe Network is 250,000. Therefore, the total number
of Impressions allocated to Globe, pursuant to this Section 6.1 herein, is ***%
of this amount, which results in *** Impressions per day being allocated to
Globe or *** on a 30-day basis.

     6.2  Use of Allocated Impressions. Globe shall be able to use its allocated
          ----------------------------
Impressions, as calculated in Section 6.1, to promote Globe or to sell to a
third party, provided the following:

          (a) if the allocated Impressions are to be used for the purposes of
promoting Globe, then they may be used on any Web site with available ad banner
inventory within the SmartClicks' Network;

          (b) if the allocated Impressions are to be used for reselling to a
third party, then they may be used on any Web site with available ad banner
inventory within the Globe Network;

          (c) allocated Impressions shall be used in a continuous and automatic
manner as mutually agreed such that any ad banners provided by Globe to SmartAge
for purposes of using such allocated Impressions shall be continuously displayed
within the SmartClicks' Network on Web sites with available ad banner inventory
unless otherwise mutually agreed.

            ***CONFIDENTIAL MATERIAL REDACTED AND FILED SEPARATELY
               WITH THE SECURITIES AND EXCHANGE COMMISSION

                                                                               5
<PAGE>

          (d) usage of such allocated Impressions is subject to the Banner
Exchange Technology and the specific terms, conditions, requirements,
limitations, and restrictions of the SmartClicks Terms and Conditions as
currently specified on Exhibit A attached hereto.

     6.3  Adjustments to Allocated Impressions.  Globe acknowledges and
          ------------------------------------
understands that SmartAge may need to adjust the number of allocated Impressions
from time to time to compensate for variations that may occur due to the unique
aspects of the scheduling and targeting of excess ad banner inventory within the
SmartClicks' Network. In the event that any such adjustment is both material in
nature and results in a reduction in the number of Impressions allocated to
Globe in any calendar quarter, SmartAge agrees to make good such reduction by
increasing the allocation of Impressions to Globe in the following calendar
quarter by the amount of any such reduction.

     6.4  Activity Reporting.  SmartAge agrees to provide Globe with access to
          ------------------
real-time reports specifying the total number of Active Globe Accounts, ad
banners shown within the Globe Network, Impressions allocated to Globe during
any prior day, the current balance of such unused Impressions, the total number
of Globe Member Sites and the URL's for each such site that were not approved by
SmartAge pursuant to Section 7.2, and any other information as mutually agreed.
Such summary report shall be accessed by Globe using a unique password via an
Internet address or in any other manner as both parties may mutually agree.
Globe shall have the right to inspect the relevant records of SmartAge for the
specific purposes of reasonably verifying such reports, provided however, that
the Globe will provide SmartAge with at least fourteen (14) business days prior
written notice before any such inspection and further provided, that Globe
agrees to limit any such inspections to no more than one (1) occasion per
calendar quarter unless it has material evidence that such records are
maintained in an unreliable or fraudulent manner. Any such inspection shall be
conducted during normal business hours and in a manner that does not
unreasonably interfere with SmartAge's business. Such activity reports shall be
substantially similar to Exhibit C attached hereto.

7.   POLICIES & PROCEDURES.

     7.1  Policies & Procedures.  All of SmartAge's normal rules, requirements,
          ---------------------
operating policies, and procedures regarding the Banner Exchange Technology and

     7.2  Approval of Member Sites and Ad Banners. Each Globe Member Site and
          ---------------------------------------
its ad banners must be approved before submitting ad banners to the Globe
Network and prior to being served using the Banner Exchange Technology. Such

to serve any ad banners promoting or referencing illegal products or services.

     7.3  Removal of Ad Banners.  At Globe's request, SmartAge shall make

     7.4. Additional Restrictions.  Globe may notify SmartAge of additional
          ------------------------

restrictions provided that they are technically feasible and further provided

and Conditions.

                                                                               6

          -------
material obligation required to be performed hereunder, and such default is not
cured within thirty (30) calendar days after written notice thereof by the other
party, then the non-defaulting party, at its option, may, in addition to any
other remedies it may have, immediately terminate the Agreement by giving

and 13.

9.   CONFIDENTIALITY.

     (a) Each party to this Agreement acknowledges that it may receive
confidential information ("Confidential Information") of the other party. For
purposes of this Agreement, Confidential Information shall mean any trade
secret, information, process, technique, algorithm, computer program (source and
object codes), design, drawing, formula, test data, business development and
marketing plans and concepts, records and files, financial data and budgetary
information, income or sales data or projections, customer lists, information
regarding customers, facilities, suppliers, plans, or market analysis.

     (b) Each party covenants and agrees that: (1) it will not, at any time,
reveal, divulge, or make known to any person, firm, corporation, or other entity
any Confidential Information of the other party; (2) it will not publish,
communicate, divulge, disclose or use such information for any purpose not
authorized by the other party, nor make copies or disclose in any manner
Confidential Information to any third party without prior written consent of the
other party; (3) it will not use the Confidential Information of the other party
for any purpose except to

                                                                               7
<PAGE>

the extent required to accomplish the intent of this Agreement; and (4) it will
return to the other party any documents (including copies, if any) containing
Confidential Information of the other party after the need for such information
has expired, or upon the request of the other party, and, in any event, upon
completion or termination of this Agreement.

     (c) Each party shall take reasonable security precautions, at least as
great as the precautions it takes to protect its own trade secrets, with respect
to the Confidential Information which it receives and shall disclose
Confidential Information on a need to know basis only to its subsidiary, agent
or subcontractor who is obligated to treat the Confidential Information in a
manner consistent with all the obligations of this Agreement.

     (d) The term Confidential Information does not include information which
the receiving party can demonstrate by competent written proof: (1) is now, or
hereafter becomes, through no act or failure to act on the part of the receiving
party, generally known or available; (2) is known to the receiving party at the
time of receiving such information as evidenced by its records; (3) is hereafter
furnished to the receiving party by a third party, as a matter of right and
without restriction on disclosure; (4) is the subject of written permission to
disclose provided by the other party; or (5) is required to be disclosed by law.

     (e) Each party agrees that any breach of obligations under this Section 9
shall be a material breach of this Agreement and result in irreparable harm to
the non-disclosing party for which damages would be an inadequate remedy and, in
addition to the rights and remedies otherwise available at law, the non-
disclosing party shall be entitled to equitable relief, including injunction, in
the event of such breach.

     10.1 Aggregate Liability.  In no event shall either party be liable for
          -------------------

election take any action, including the settlement of any Claim, without further
notice to the Indemnifying Party, and without waiving any rights or Claims

                                   EXHIBIT A

By joining the SmartClicks ad network, members have indicated agreement to the
following terms and conditions. Compliance with the terms and conditions ensures
that only appropriate sites become SmartClicks members and that all network
advertising meets SmartClicks standards.

Any account or member violating these terms will be immediately removed from the
SmartClicks ad network.

1. SmartClicks reserves the right to refuse to continue membership to any Web
site in the SmartClicks network that contains or has links to nudity, sexual
situations, pornography, hate groups, illegal activities, offensive material or
for any other reason.

2. SmartClicks reserves the right to refuse to continue membership to any Web
site deemed to be competition, including, but not limited to, other banner
exchange services.

3. SmartClicks reserves the right to reject any banner that contains nudity,
profanity, offensive material or for any other reason.

4. Members agree to insert the provided SmartClicks HTML code for displaying
banners on their Web site. The SmartClicks HTML code may not be modified in any
way without written permission from SmartClicks.

5. Only one (1) SmartClicks banner may be placed on a page. A page is what is
displayed on one screen, so members who use frames must count all individual
pages in the frame as one page for banner placement purposes.

6. SmartClicks ad network banners must be displayed on the page such that the
banner is easily visible. Banners may not be "hidden" so that a visitor has no
way to view the banner.

7. SmartClicks banners must remain static on the member's Web site, and may not
be rotated with those of any other banner exchange service.

8. A member may not artificially inflate traffic counts to his/her site using
any device, program, robot or other means. A banner may not be placed on a page
that reloads automatically. Banners loaded via the SmartClicks HTML may not be
placed in newsgroups, e-mail, chat rooms or guestbooks, unless permission is
granted from SmartClicks. Any member whose account is terminated for
artificially inflated traffic counts may offer a defense to have the account re-
instated. SmartClicks' logs and/or judgments in these matters will prevail.

9. A member may not display the SmartClicks HTML on sites other than the one to
which the account is addressed to click through to, unless written permission is
granted from SmartClicks. A member may display the SmartClicks HTML on any of
the pages on the site, as long as there is a path of links from the page that
the banner clicks through to, to the page on which the banner is displayed.

10. A banner that appears on a member site may at any time be a banner for
another member, for a sponsor or partner, for SmartClicks or for other SmartAge
services. Ratings restrictions apply.

11. SmartClicks reserves the right not to accept any advertisements from
entities whose product or advertisement are deemed by SmartClicks to be
inappropriate, or for any other reason.

12. Members may cancel their accounts with the SmartClicks ad network at any
time by sending a request for

                                                                              11
<PAGE>

cancellation, containing the account number and password of the account in
question, via e-mail to accounts@smartclicks.com, and removing the SmartClicks
HTML code from the Web site. Cancellations take place immediately.

13. The SmartClicks name, logo, software, databases, reports, Web site and
information are proprietary and cannot be used without permission from
SmartClicks. Exception: each member has the right to use information compiled by
SmartClicks for the member's site or in the promotion of the member's site.

14. Members agree that their Web site information (name, URL, traffic counts,
etc.) may be used by SmartClicks.

15. The information members provide to SmartClicks will be kept confidential and
will not be distributed, except in aggregate, to any outside agency, without the
permission of the member.

16. SmartClicks, its administrators, partners and sponsors cannot be held liable
for any damage or loss of information that may occur from the use of
SmartClicks' services.

17. Members agree to use SmartClicks at their own risk.

18. SmartClicks makes every effort to verify and maintain a high standard of
service quality, but SmartClicks does not make any guarantees regarding the
dependability or accuracy of SmartClicks' services.

19. SmartClicks will attempt to correct inconsistencies in credits due any
member based on the member's proof of inconsistency.

20. SmartClicks reserves the right to modify or change these Terms and
Conditions at any time, as it deems necessary. It is the member's responsibility
to keep current with changes in the Terms and Conditions, since changes are
effective for all members, regardless of when the member joined. Updates will be
evident by the date modified on the home page.
