This DoubleClick Master Services Agreement (the "Agreement") is by and between
DoubleClick Inc. and L90, Inc. ("Company" or "You"). For good and valuable
consideration, the receipt of which is acknowledged by each party, the parties
agree as follows:

1. SERVICES. DoubleClick shall provide various services (the "Service(s)") to
Company according to written attachments to this Agreement upon which the
parties may agree from time to time (each, an "Attachment"). Each Attachment,
which shall be incorporated into the Agreement by reference and made a part
hereof, shall contain additional terms and conditions that are specific to the
Service that is the subject of such Attachment. Each Attachment shall specify
which of the Web site(s) listed above (collectively, the "Web Site") are covered
by such Attachment. The term "Service(s)" as used in this Agreement shall be
deemed to include all Services set forth in Attachments hereto. A current list
of Services offered by DoubleClick includes, without limitation, the following:
DART for Publishers, DART for Advertisers/Agencies, DARTmail for Publishers,
Email Services, Email List Management, mDART (wireless), Advanced Reporting,
Boomerang, MediaMatch, Brand Network representation, Audience Network
representation, and DoubleClick Sweepstakes. DoubleClick may offer additional
Services from time to time as such additional Services are developed. An
Attachment to this Agreement will not be binding unless it is executed by both
parties. In the event Company has an existing agreement(s) with DoubleClick for
a particular DoubleClick service which agreement(s) is not superceded by an
Attachment to this Agreement for such Service (a "Pre-Existing Agreement"), such
Pre-Existing Agreement shall be supplemental to this Agreement and shall remain
in full force and effect to govern the particular relationship between the
parties as set forth in such Pre-Existing Agreement.

2. PAYMENT. Should DoubleClick perform an ad or email sales Service (e.g., Brand
Network representation, Audience Network representation, or Email List
Management representation, collectively, "Representation Services") on behalf of
Company, the payment obligations for such Service shall be set forth in the
Attachment for

                                                               Master Agreement
                                                                         Page 1

such Service. For all other Services and unless otherwise stated in an
Attachment for a particular Service, Company shall pay DoubleClick the
undisputed fees set forth in the applicable Attachments for such Services within
thirty (30) days after Company's receipt of an invoice from DoubleClick. All
fees hereunder shall be denominated in U.S. dollars and shall be paid by Company
check, or by other means expressly agreed to in writing by DoubleClick. Company
shall also be responsible for and shall pay any applicable sales, use or other
taxes or duties, tariffs or the like applicable to provision of the Services
(except for taxes on DoubleClick's income). Late payments by Company for
undisputed fees will be subject to late fees at the rate of one percent (1.0%)
per month, or, if lower, the maximum rate allowed by law. If Company fails to
pay fees invoiced by DoubleClick, which are not disputed by Company in good
faith, within thirty (30) days following the payment due date (i.e., 60 days
after receipt of invoice), DoubleClick shall have the right to suspend
performance of the applicable Service(s) without notice to Company. The
Service(s) shall not be reinstated until Company pays all such overdue amounts.

3. PROPRIETARY RIGHTS AND RESTRICTIONS. The parties agree that (a) Company shall
retain all proprietary rights in and to the Web Site(s), its business and
trademarks and (b) DoubleClick retains all proprietary rights in and to all of
DoubleClick's intellectual property, including but not limited to the DART and
DARTmail technology, any Services provided hereunder (including all software,
source codes, modifications, updates and enhancements thereof or any other
aspect of the Services), the name "DoubleClick" or any derivatives thereof, and
any other trademarks and logos which are owned or controlled by DoubleClick and
made available to Company through the Service or otherwise. No implied licenses
are granted herein, and Company may not use any Service except pursuant to the
limited rights expressly granted in this Agreement.

4. TERM. Unless earlier terminated in accordance with the termination rights set
forth in this Agreement, the term of each Attachment shall be as set forth in
the applicable Attachment. This Agreement shall commence as of the Effective
Date, and remain in effect until all Attachments hereto have terminated, unless
terminated earlier in accordance with the termination rights set forth in this
Agreement and the Attachments (the "Term").

5. TERMINATION. Unless terminated earlier in accordance with the termination
rights set forth below, the term of this Agreement shall be for a period of five
(5) years from the Effective Date. Unless terminated by either party upon sixty
(60) days' notice prior to the end of the initial term or any renewal term, the
Agreement shall automatically renew for successive one year terms. At any time
during the Term, an Attachment shall terminate (i) unless governed by (ii)
below, thirty (30) days after a party's receipt of notice that such party is in
material breach of any of the terms or conditions set forth in such Attachment,
unless such party cures such breach within said thirty (30) day period, (ii)
sixty-five (65) days after Your receipt of notice that You are in material
breach of any of the terms and conditions set forth in this Attachment, which
breach is substantially attributable to the acts or omissions of a Web Site that
You represent, unless such breach is cured within said sixty-five (65) day
period and You have used reasonable and diligent efforts throughout said period
to effect such cure, (iii) in any of the three initial thirty (30)-day periods
following the end of the Initial Migration Period (as defined in the Interim
Services Agreement), the DFP Services delivers fewer than [*] impressions in the
aggregate on behalf of the Web Sites, or (iv) immediately upon notice by a party
if the other party (a) is adjudged insolvent or bankrupt, (b) institutes or has
instituted against it any proceeding seeking relief, reorganization or
arrangement under any laws relating to insolvency (and, in the case of any such
proceeding instituted against it, the proceeding is not dismissed within sixty
(60) days after filing), (c) makes any assignment for the benefit of creditors,
(d) appoints a receiver, liquidator or trustee of any of its property or assets,
or (e) liquidates, dissolves or winds up its business. Company has the right to
terminate the Agreement on ninety (90) days prior written notice to DoubleClick
in the event that Company either (a) discontinues its media business, or (b)
enters into an agreement with a third party to use a different ad serving
technology on an exclusive basis. Subject to force majeure provisions set forth
in Section 16 herein, DoubleClick has the right to terminate this Agreement
immediately upon written notice to Company in the event that its media business
(other than during the initial three (3) months of this Agreement) serves less
than [*] ad impressions per month in the aggregate. [*] Company shall also
immediately cease all use of and remove all Tags from the Web Site. For the
purposes of this Agreement, "Tag" shall mean any HTML code provided by
DoubleClick and incorporated into the Web Site.

6. REPRESENTATIONS AND WARRANTIES. Each party warrants and represents at all
times that (i) it has the right and full power and authority to enter into this
Agreement, and (ii) it is duly organized and validly existing and in good
standing under the laws of the state of its incorporation or formation.

7. INDEMNIFICATION. Company agrees to indemnify and hold DoubleClick and its
officers, directors, employees and agents (each a "DoubleClick Indemnitee")
harmless from and against any and all third party claims, actions, losses,
damages, liabilities, costs and expenses (including, without limitation,
reasonable attorneys' fees and disbursements incurred by a DoubleClick
Indemnitee in any action between Company and the DoubleClick Indemnitee, or
between the DoubleClick Indemnitee and any third party or otherwise) arising out
of or in connection with the breach of any of Company's representations,
warranties or obligations set forth in this Agreement.

DoubleClick agrees to indemnify and hold Company and its officers, directors,
employees and agents (each a "Company Indemnitee") harmless from and against any
and all third party claims, actions, losses, damages, liabilities, costs and
expenses (including, without limitation, reasonable attorneys' fees and
disbursements incurred by a Company Indemnitee in any action between DoubleClick
and the Company Indemnitee, or between the Company Indemnitee and any third
party or otherwise) arising out of or in connection with the breach of any of
DoubleClick's representations, warranties or obligations set forth in this
Agreement.

The indemnification obligations set forth in this Section 7 hereof are
contingent upon the following conditions: (i) DoubleClick or Company, as the
case may be (the "Indemnified Party") must promptly notify the Company or
DoubleClick as the case may be (the "Indemnifying Party") in writing of the
third party claim or action (however, failure of the Indemnified Party to so
promptly notify the Indemnifying Party will not relieve the Indemnifying Party
of its indemnification obligations hereunder, except to the extent it has been
damaged thereby); (ii) the DoubleClick Indemnitee or the Company Indemnitee, as
the case may be, and the Indemnified Party will reasonably cooperate with the
Indemnifying Party in the defense of the matter; and (iii) the Indemnifying
Party will have primary control of the defense of the action and negotiations
for its settlement and compromise; provided, however, that the Indemnified Party
may, at its own cost, obtain separate counsel to represent its interests.

8. DISCLAIMER AND LIMITATION AND EXCLUSION OF LIABILITY. EXCEPT AS EXPRESSLY
PROVIDED ABOVE OR IN AN ATTACHMENT, NEITHER PARTY MAKES ANY WARRANTIES OF ANY
KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTY OF
MERCHANTABILITY OR FITNESS OF THE SERVICES HEREUNDER FOR A PARTICULAR PURPOSE.
DOUBLECLICK SHALL NOT BE LIABLE FOR ANY ADVERTISERS WHOSE ADVERTISING APPEARS ON
THE SERVICE, NOR THE CONTENTS OF ANY ADVERTISING (PROVIDED THAT DOUBLECLICK HAS
PROPERLY PROVIDED THE SERVICES DESCRIBED HEREIN), NOR SHALL DOUBLECLICK HAVE ANY
OBLIGATION TO REVIEW THE CONTENT OF ANY ADVERTISING SERVED THROUGH THE
APPLICABLE SERVICE. IF OUTSIDE THE CONTROL OF DOUBLECLICK AND ITS VENDORS,
DOUBLECLICK SHALL NOT BE LIABLE TO COMPANY OR ANY THIRD PARTY FOR ANY
UNAVAILABILITY OR INOPERABILITY OF THE SERVICES, TELECOMMUNICATIONS SYSTEMS OR
THE INTERNET, TECHNICAL MALFUNCTION, COMPUTER ERROR, CORRUPTION OR LOSS OF
INFORMATION, OR OTHER INJURY, DAMAGE OR DISRUPTION OF ANY KIND. IN NO EVENT WILL
EITHER PARTY BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR
EXEMPLARY DAMAGES, INCLUDING, BUT NOT LIMITED TO, LOSS OF PROFITS, OR LOSS OF
BUSINESS OPPORTUNITY, EVEN IF SUCH DAMAGES ARE FORESEEABLE AND WHETHER OR NOT
SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY THEREOF. OTHER THAN FOR
DOUBLECLICK'S ACTS OF GROSS NEGLIGENCE AND WILLFUL MISCONDUCT, DOUBLECLICK'S
MAXIMUM AGGREGATE LIABILITY FOR EACH ATTACHMENT SHALL NOT EXCEED THE GREATER OF
(A) THE TOTAL AMOUNT (INCLUDING ANY TRUE-UP FEES) PAID BY COMPANY TO DOUBLECLICK

9. CONFIDENTIALITY. The terms of this Agreement and all information and data
that one party (the "Receiving Party") has received or will receive from the
other party (the "Disclosing Party") about the Service, DoubleClick's
proprietary DART and DARTMail systems and other matters are proprietary and
confidential information ("Confidential Information"), including without
limitation any information that is marked as "confidential" or should be
reasonably understood to be confidential or proprietary to the Disclosing Party
and any reference manuals compiled or provided hereunder. The Receiving Party
agrees that during the Term of this Agreement and for two (2) years thereafter,
the Receiving Party will not disclose any Confidential Information to any third
party, nor use any Confidential Information for any purpose not permitted under
this Agreement. The nondisclosure obligations set forth in this Section shall
not apply to information that (a) is in, or becomes in, the public domain
without violation of this Agreement by the Receiving Party, (b) was known to the
Receiving Party prior to disclosure thereof to the Receiving Party by the
Disclosing Party as evidenced by written records, (c) is disclosed to the
Receiving Party by a third party under no obligation of confidentiality to the
Disclosing Party and without violation of this Agreement by the Receiving Party,
or (d) is independently developed or discovered by the Receiving Party without
reference to any Confidential Information. Notwithstanding any other provisions
in this Agreement, the Receiving Party may disclose Confidential Information to
the extent required by any applicable law, regulation, or court or governmental
order; provided that the Receiving Party gives the Disclosing Party reasonable
advance written notice of any such disclosure or any request or demand for such
disclosure.

10. INDEPENDENT CONTRACTOR STATUS. Each party shall be and act hereunder as an
independent contractor and not as partner, joint venturer or agent of the other.

11. MODIFICATIONS AND WAIVERS. This Agreement, which includes all Attachments
hereto, represents the entire understanding between DoubleClick and Company and,
excluding any Pre-Existing Agreements, supersedes all prior agreements relating
to the subject matter of this Agreement. No failure or delay on the part of
either party in exercising any right, power or remedy under this Agreement shall
operate as a waiver, nor shall any single or partial exercise of any such right,
power or remedy preclude any other or further exercise of any other right, power
or remedy. Unless otherwise specified, any amendment, supplement or modification
of or to any provision of this Agreement, any waiver of any provision of this
Agreement and any consent to any departure by the parties from the terms of this
Agreement, shall be effective only if it is made or given in writing and signed
by both parties.

12. ASSIGNMENT. This Agreement and the rights hereunder are not transferable or
assignable without the prior written consent of the non-assigning party;
provided, however, that this Agreement may be assigned by either party without
the other party's written consent to a person or entity who acquires
substantially all of such party's assets, stock or business by sale, merger or
otherwise.

13. APPLICABLE LAW AND CONFLICTS. This Agreement shall be governed by the laws
of New York, without reference to its conflict of laws rules or principles. The
jurisdiction and venue for all disputes hereunder shall be the state and federal

conditions of the Agreement and the terms and conditions of any Attachment, the
terms and conditions of the Attachment shall govern.

14. PUBLICITY. The parties will work together in a fair, positive and accurate
manner to issue publicity and general marketing communications concerning their
relationship, Company's use of DoubleClick's Services, and other mutually
agreed-upon matters. Except as otherwise required by applicable law, regulation,
or court or governmental order, neither party will issue any publicity or
general marketing communications concerning this relationship without the prior
written consent of the other party; provided, however,

15. PRIVACY. Company acknowledges that adherence to fair information collection
practices is of utmost importance to DoubleClick. During the term of this
Agreement, Company agrees that those Web Sites that are owned, controlled or
operated by Company will feature an easy-to-understand privacy policy, linked at
a minimum from the Web Site's home page, that, (i) in addition to the
disclosures about Company's privacy practices, identifies the collection and use
of information gathered in connection with DoubleClick's ad serving and
reporting activities and (ii) offers the user an opportunity to opt out from
such collection and use. Furthermore, during the term, Company agrees to use
best efforts to cause those Web Sites that are represented by Company (but not
owned, controlled or operated by it) to feature an easy-to-understand privacy
policy that satisfies the requirements in (i) and (ii) above. DoubleClick
suggests the following language be added to each Web Site's privacy policy to
satisfy the requirements in (i) and (ii) above if DoubleClick is performing ad
serving services for Company: "We use a third-party advertising company to serve
ads when you visit our site [if using DFA, add and sites upon which we
advertise]. This company may use information (not including your name, address,
email address or telephone number) about your visits to our and other web sites,
in combination with non-personally identifiable information about your purchases
and interests from other online and offline sources, in order to provide
advertisements about goods and services of interest to you. In addition, we
share web site usage information about visitors to our sites with this company
for the purpose of managing and targeting advertisements and for market research
analysis on our site and other sites. For these purposes, we and our third-party
advertising company may note some of the pages you visit on our site through the
use of pixel tags (also called clear gifs). In the course of serving
advertisements to this site, our third-party advertiser may place or recognize a
unique 'cookie' on your computer. If you would like more information about the
information collection practices of this third-party advertising company and to
know your choices about not having this information used by this company, click
here." [LINK TO URL to be provided by DoubleClick; see, for example,
http://www.doubleclick.net/us/corporate/privacy or
http://www.doubleclick.net/naiprivacy (if Company has existing relationships
with other NAI companies)]. Other Service-specific disclosure requirements are
set forth in the applicable Service Attachment. DoubleClick reserves the right
to change its suggested disclosure upon written notice to Company.

16. GENERAL. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
only to the minimum extent necessary without invalidating the remaining
provisions of this Agreement or affecting the validity or enforceability of such
provisions in any other jurisdiction. No failure or omission by either party in
the performance of any obligation under this Agreement shall be deemed a breach
of this Agreement nor create any liability if the same shall arise from any
cause or causes beyond the reasonable control of such party, including but not
limited to the following: acts of God, acts or omissions of any government or
any officer, department, agency or instrument thereof; fire, storm, flood,
earthquake, accident, acts of the public enemy, war, rebellion, failure of
telecommunications services, public utilities or an Internet brown out,
insurrection, riot, invasion, strikes, or lockouts. All notices, demands and
other communications provided for or permitted under this Agreement shall be
made in writing to the parties at the addresses on the Cover Page and shall be
sent by registered or certified first-class mail, return receipt requested,
telecopier, courier service or personal delivery and shall be deemed received
upon delivery.

1.  DESCRIPTION OF SERVICES.

1.1 If Company chooses to participate in the DoubleClick MediaMatch service
("MediaMatch Service"), Company agrees to offer banner impression space on its
Web Site to other companies participating in the MediaMatch Service
("Participants"), in return for placement of Company's ads ("Company Ads") on
the sites of other Participants. For each impression on Company's Web Site that
Company redirects to the MediaMatch Service, DoubleClick, using DoubleClick's
proprietary DART ad delivery technology, shall (a) deliver an ad of one of the
Participants ("Participant Ads") to users accessing the Web Site, and (b)
deliver a Company Ad to users accessing the Web site of another Participant.
Such delivery shall be in accordance with this Exhibit. Capitalized terms used
herein but not otherwise defined herein shall have the meanings assigned to such
terms in the Master Agreement or DFP Attachment.

1.2 DoubleClick's sole obligations hereunder shall be to use reasonable efforts
to (a) deliver the designated number of Participant Ads to the Web Site, (b)
within three days, serve the same number of Company Ad impressions to Web sites
of other Participants, and (c) traffic Company Ads appearing on Participant Web
sites in accordance with the criteria set by Company and this Exhibit.

2. MEDIAMATCH TERM AND TERMINATION. The term of the MediaMatch Service shall be
co-terminus with the DFP Term. In addition, either party will have the right to
terminate the MediaMatch Service at any time for any reason upon three (3) days
written notice to the other.

3. FEES. Company agrees to pay to DoubleClick the MediaMatch Fees specified on
the cover page to this Exhibit for the number of Company Ads of each applicable
size served by DoubleClick hereunder. These Fees are supplemental to any serving
fees Company may owe to DoubleClick or any other third-party ad serving company.
Company's MediaMatch fees will be separately set out in Company's DFP invoice.

4.      COMPANY OBLIGATIONS.

4.1 COMPANY ADS. Company is responsible for submitting to DoubleClick all
Company Ad information and creative to be served as part of the MediaMatch
Service. Company may change the Company Ad information or creative at any time,
and DoubleClick will use commercially reasonable efforts to ensure that such
change shall take effect within three (3) business days. Company must provide
DoubleClick with at least one standard .gif image, and may provide DoubleClick
with other creative(s). If Company has rich media creative(s) in addition to
standard .gif images, the rich media creative will be served on the Participant
sites if those sites are tagged for rich media, but if those sites are not
tagged for rich media, then the standard .gif image(s) will be served instead.
Company shall be solely responsible for all costs it incurs in connection with
the MediaMatch Service and this Exhibit, including, without limitation, expenses
associated with creating, updating and otherwise managing Company Ads,
delivering Company Ads to the MediaMatch Service and establishing and
maintaining links between Company Ads and Web sites and areas outside the
MediaMatch Service (collectively, "Company's Web Content").

4.2 INVENTORY REDIRECTS. Company will enable the exchange of inventory by
placing the HTML tags provided by DoubleClick into either the code of the
Company's Web Site or into a redirect ad within the ad serving software that
Company uses to manage its ad inventory. Company is responsible for trafficking
these redirect ads that enable Participant Ads to deliver to the Company Web
Site. If Company changes the number of impressions it redirects to DoubleClick
or terminates this MediaMatch Service for any reason, Company shall allow
DoubleClick to first reconcile the amount of Participant impressions that have
been served to the Web Site with the number of Company Ad impressions that have
been served to Participant sites.

4.3 REVIEW AND RESTRICTION OF PARTICIPANTS' ADS. Company, using DoubleClick's
proprietary Ad Manage system, may prevent Participant Ads from delivering to the
Web Site that Company reasonably believes are inappropriate for placement on the
Web Site, it being understood that excessive banning of Participant Ads may
reduce the number of Company Ads that appear on Participants' Web sites. Ad
Manage allows Company to ban Participant Ads (a) based upon review of the
creatives of each individual Participant Ad, or (b) based upon the click-through
URL(s) associated with the Participant Ads. Company agrees that DoubleClick has
no responsibility to review the contents of any ads appearing on the Web Site.

5.  DOUBLECLICK'S RIGHTS.

consent. DoubleClick shall have the right to use information concerning number
of impressions, users, and user activity for DoubleClick's own business
purposes.

5.2 DoubleClick and/or the Participants shall have the right, in their sole
discretion, to terminate the delivery of any Company Ad at any time without
liability to Company, provided that such termination shall correspondingly
reduce the number of Participant Ads to appear on the Company Web Site.

6. MISCELLANEOUS. DoubleClick is the owner of all right, title and interest in
and to DoubleClick MediaMatch technology, DoubleClick MediaMatch trademarks and
all information and materials provided to Company regarding DoubleClick
MediaMatch. The DART ad delivery technology shall be the sole and definitive
tool used to measure the MediaMatch Service's delivery of Company and
Participant Ads pursuant to this Exhibit. No other measurement or usage

shall be accepted by DoubleClick.
