2.       GRANT OF RIGHTS

2.1 Grant of License. Subject to the terms and conditions of this Agreement,
DoubleClick hereby grants to Licensee a perpetual, worldwide, nonexclusive,
license, to install and use the number of copies of each Program Component of
the Software as indicated on Exhibit A to manage the Programming on Zap.Com's
Sites and the ZapNetwork Site(s), on third party Websites and throughout the
Internet, including, but not limited to, manage Programming remotely from
Zap.Com's Servers for the ZapBox or other Zap.Com Internet properties on
ZapNetwork Sites. No license is granted to Licensee to distribute the Software
to its customers. Licensee may permit limited access to the Software on
Zap.Com's Servers and use of such Software by (a) customers of Zap.Com only so
long as such customers remain customers of Zap.Com and (b) any of the ZapNetwork
Sites, provided that such customers and owners of the ZapNetwork Sites have
acknowledged in writing that the Software is licensed and their rights are
limited to use on Zap.Com's
<PAGE>   4
Servers and have agreed in writing not to download, copy, distribute or attempt
to make any other unauthorized use of the Software. Licensee may make backup
copies of the Software for archival or disaster recovery purposes.

2.2 Restrictions. The license granted herein is granted solely to the person or
entity set forth on Exhibit A and the Licensee's parent and subsidiaries and to
no one else. All rights not expressly granted hereunder are reserved to
DoubleClick. Licensee may not copy, distribute, reproduce, use or allow access
to the Software except as explicitly permitted under this Agreement, and
Licensee will not modify, adapt, translate, prepare derivative works from,
decompile, reverse engineer, disassemble or otherwise attempt to derive source
code from the Software or any internal data files generated by the Software
except to the extent allowed by applicable law or as permitted in a separate
written agreement with DoubleClick; provided, however that nothing in this
Section 2.2 shall restrict in any way Licensee's right to use the AdServer
Software application programming interface to connect the Software to other
software and/or hardware products, including any software or hardware not
provided by DoubleClick. Licensee shall not remove, obscure, or alter
DoubleClick's copyright notice, trademarks, or other proprietary rights notices
affixed to or contained within the Software; provided, however, such notices,
trademarks, or other proprietary rights notices shall be hidden from viewers of
pages on ZapNewwork Sites or which are delivered by Licensee.

2.3 Ownership. DoubleClick owns and shall retain all right, title, and interest
in and to the Software, including all copyrights, patents, trade secret rights,
trademarks and other intellectual property rights therein. Licensee will, within

by DoubleClick only once in each consecutive twelve (12) month period), at the
Licensee's option, either permit DoubleClick to inspect Zap.Com's facilities to
confirm that the Licensee is materially complying with the terms of this
Agreement or have Licensee provide a written certification that Licensee is
materially complying with the material terms of this Agreement that apply to it
which shall be signed by an officer of Licensee. Zap.Com's failure to permit
such access or Licensee's failure to provide such officer's certification shall
be deemed a material breach of this Agreement if DoubleClick provides an
additional written notice to Licensee stating that a material breach under this
Agreement will be deemed to occur if compliance does not occur within fifteen
(15) days of delivery of such second notice.

3.       DELIVERY OF THE SOFTWARE

DoubleClick shall deliver the Software electronically (or by other means
mutually agreed upon by the parties) to Licensee at the location(s) set forth on

3.2 Installation and Training. At Licensee's request, following delivery of the
Software, DoubleClick will provide reasonable assistance, at no additional
charge, to Licensee by telephone and e-mail to the extent necessary for Licensee
to install the Software. Additionally, Doubleclick shall provide, at no
additional charge, on-site installation assistance and training ("SureStart") as
listed on Exhibit A. The SureStart process is designed to install the Software.
For purposes of this Agreement, "Installation Date" shall mean the first date on
which all Program Components discussed in Section 1.2 of this Agreement and
defined on Exhibit A of this Agreement are functioning and that the Software can
deliver advertisements to the World Wide Web. The parties shall work together in
good faith towards an Installation Date of no later than April 01, 2000.

4.1 License Fee. In consideration for the rights granted hereunder, Licensee
shall pay DoubleClick license fees in the amounts and on the payment terms set
forth on Exhibit A.

4.2 Taxes. Licensee shall be responsible for all sales taxes, use taxes and any
other similar taxes imposed by any federal, state or local governmental entity
on the transactions contemplated by this Agreement, excluding U.S. taxes based
upon DoubleClick's income. When DoubleClick has the legal obligation to pay or
collect such taxes, the appropriate amount shall be invoiced to and paid by
Licensee unless Licensee provides DoubleClick with a valid tax exemption
certificate authorized by the appropriate taxing authority.

4.3 U.S. Dollars. All fees quoted and payments made hereunder shall be in U.S.
Dollars.

5.       DOUBLECLICK SUPPORT

At Licensee's request, DoubleClick will offer to Licensee maintenance and

                                      -2-
<PAGE>   5
standard Software Maintenance Subscription and Support Agreement, a copy of
which is attached as Exhibit B. The Software and Maintenance Subscription and
Support Agreement shall be fully assignable by Licensee to Zap.Com at any time
without any notice to, or required consent by DoubleClick.

6.       WARRANTY AND DISCLAIMER

6.1 Functional Warranty. DoubleClick warrants that for a period of ninety (90)
days following the Installation Date: (i) the Software shall operate
substantially in accordance with the then current documentation for such
Software, (ii) the Software shall schedule Programming through the AdManager,
deliver ads to ZapNetwork Sites, and have the ability to count and report
impressions, clickthroughs, and yield and the media on which the Software is
furnished shall be free from defects in materials and faulty workmanship under
normal use. Except as expressly provided herein, DoubleClick does not warrant
that the Software will meet all of Licensee's requirements or that the use of
the Software will be uninterrupted or error-free. DoubleClick's sole obligation
under this warranty is to use commercially reasonable efforts to promptly
correct any non-conforming Software to conform with this warranty and if the
Software cannot be corrected to return to Licensee the license fees paid
hereunder. EXCEPT AS EXPRESSLY PROVIDED HEREIN, DOUBLECLICK LICENSES THE
SOFTWARE TO LICENSEE ON AN "AS IS" BASIS. DOUBLECLICK MAKES NO OTHER WARRANTY OF
ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE INCLUDING WITHOUT
LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE.

6.2 Additional Warranties. DoubleClick warrants that it has the right to grant
the rights granted under this Agreement.

6.3 Year 2000 Warranty. DoubleClick further warrants that the Software shall
correctly process, provide and/or receive date data within and between the 20th
and 21st centuries, provided that all products used with the Software properly
exchange date data with the Software. In the event DoubleClick becomes aware
that the Software will not or does not process dates containing any date
subsequent to the year 1999 correctly, DoubleClick shall immediately notify
Licensee of that fact.

7.       INDEMNIFICATION

7.1 By DoubleClick. DoubleClick shall indemnify, and hold harmless Licensee from
any and all damages, liabilities, costs and expenses (including reasonable
attorneys' fees) incurred by Licensee as a result of any claim that the
Software, when used within the scope of this Agreement, infringes any copyright,
trademark, patent, trade secret or other intellectual property right of any
third party. Licensee shall promptly notify DoubleClick in writing of any such
claim and promptly tenders the control of the defense and settlement of any such
claim to DoubleClick at DoubleClick's expense and with DoubleClick's choice of
counsel to Licensee, provided that Licensee's failure to do any of the foregoing
shall not relieve DoubleClick of its obligations hereunder except to the extent
that it is actually prejudiced thereby and provided further that DoubleClick
shall not settle any such claim in a manner that would require Licensee to act
other than is expressly set forth in this Agreement without prior written
consent of Licensee. Licensee shall cooperate with DoubleClick, at
DoubleClick's expense, in defending such claim. Licensee may join in defense
with counsel of its choice at its own expense. If the Software is, or in the
opinion of DoubleClick may become, the subject of any claim for infringement or
if it is adjudicatively determined that the Software infringes then DoubleClick
may, at its option and sole expense, either (i) procure for Licensee the right
from such third party to use the Software or (ii) replace or modify the Software
with other suitable and reasonably equivalent products which complies with the
representations and warranties herein so that the Software becomes
non-infringing so long as Licensee does not experience an interruption in
service due to any infringement or (iii) if (i) and (ii) are not practicable,
terminate this Agreement on sixty (60) days advance written notice. If
DoubleClick terminates under subsection (iii) within five (5) years after the
execution of this Agreement, DoubleClick will refund a pro-rata portion of the
license fees based on a five year life of the Software (the refundable amount
being determined by the total license fees reduced each month by 1/60th of the
total). If DoubleClick terminates under subsection (iii) at any time after the
Effective Date, DoubleClick will refund any prepaid subscription and support
fees applicable to the remaining period for which the services will be
terminated.

7.2 Exclusions. DoubleClick shall have no liability for any infringement to the
extent that it arises from (i) the use of other than the then-current,

                                      -3-
<PAGE>   6
commercially available version of the Software following the third month after
the release by DoubleClick of such version; (ii) the use of the Software other
than for serving advertisements on the World Wide Web or as otherwise set forth
in its accompanying documentation; or (iii) the modification of the Software
unless such modification was made or authorized by DoubleClick, when such
infringement would not have occurred but for such modification or (iv) the
combination or use of the Software with other software, hardware or other
products not approved by DoubleClick in advance if such infringement would have
been avoided by the use of the Software not in such combination. THIS SECTION 7
STATES DOUBLECLICK'S ENTIRE OBLIGATION WITH RESPECT TO ANY CLAIM REGARDING THE
INTELLECTUAL PROPERTY RIGHTS OF ANY THIRD PARTY.

8.       LIMITATION OF LIABILITY

EXCEPT IN REGARDS TO DOUBLECLICK'S OBLIGATIONS UNDER SECTION 7 HEREIN, IN NO
EVENT WILL DOUBLECLICK'S LIABILITY ARISING OUT OF THIS AGREEMENT OR THE USE OR
PERFORMANCE OF THE SOFTWARE EXCEED THE SUM OF THE LICENSE FEES ACTUALLY PAID BY
LICENSEE HEREUNDER. IN NO EVENT SHALL EITHER PARTY HAVE ANY LIABILITY TO THE
OTHER PARTY FOR ANY LOST PROFITS OR COSTS OF PROCUREMENT OF SUBSTITUTE GOODS OR
SERVICES, OR FOR ANY INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES, HOWEVER CAUSED
AND UNDER ANY THEORY OF LIABILITY AND WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED
OF THE POSSIBILITY OF SUCH DAMAGE; PROVIDED, HOWEVER, THAT THIS LIMITATION SHALL
NOT APPLY TO ANY BREACH BY LICENSEE OF THE LICENSE RESTRICTIONS IN SECTION 2 OR
ITS CONFIDENTIALITY OBLIGATIONS IN SECTION 9. THE PARTIES AGREE THAT THIS
SECTION 8 REPRESENTS A REASONABLE ALLOCATION OF RISK.

prevent the disclosure and unauthorized use of Confidential Information of the
other party.

9.3 Exceptions. Notwithstanding the above, the restrictions of this Section
shall not apply to information that:

         (a) was independently developed by the receiving party without any use
of the Confidential Information of the other party and by employees or other
agents of (or independent contractors hired by) the receiving party who have not
been exposed to the Confidential Information;

         (b) becomes known to the receiving party, without restriction, from a
third party without breach of this Agreement and who had a right to disclose it;

         (c) was in the public domain at the time it was disclosed or becomes in

         (d) was rightfully known to the receiving party, without restriction,
at the time of disclosure; or

         (e) is disclosed pursuant to the order or requirement of a court,
administrative agency, or other governmental body; provided, however, that the
receiving party shall provide prompt notice thereof to the other party and shall
use its reasonable best efforts to obtain a protective order or otherwise
prevent public disclosure of such information.

by Licensee or any of its officers, employees, consultants or other agents.

                                     BETWEEN

                                DOUBLECLICK, INC.

                                       and

                               ZAP.COM CORPORATION

         DoubleClick, Inc. ("DoubleClick") has granted Zap.Com Corporation
("Licensee") a license to certain software in accordance with a DoubleClick
Adserver Network License Agreement dated December 23, 1999 (the "License
Agreement"). Licensee wishes to obtain maintenance and support of such software
pursuant to this Agreement.

                                    SECTION 1
                                   DEFINITIONS

1.1 "Product(s)" means the software programs licensed to Licensee pursuant to
the License Agreement together with any Updates and Upgrades furnished by
DoubleClick to Licensee under this Agreement and any modifications to the
Products furnished to Licensee under the product warranty in the License
Agreement.

1.2 "Updates" means a software Product release containing error corrections and
minor enhancements, in object code form, which is made commercially available by
DoubleClick and generally indicated by a change in the revision number in the
tenths or hundredths digit to the right of the decimal point (e.g., a change
from version x.xx to x.xy or x.yx) and any corrections and updates to the
associated documentation.

1.3 "Upgrades" means a software Product release containing significant
functional enhancements and feature additions of the Software, in object code
form, which is made commercially available by DoubleClick and generally
indicated by a change in the revision number to the left of the decimal point
(i.e., 4.00).


                                    SECTION 2
                                TECHNICAL SUPPORT

2.1 Support. DoubleClick will provide Licensee with technical support
("Support") during the hours indicated on the attached Schedule 1. Support will
be provided by at least one of the following methods: telephone, email, World
Wide Web, or fax. DoubleClick, at its sole discretion, will choose which
method(s) it uses to provide support to Licensee. Support will include:

         (a) assistance related to questions on the installation and operational
use of the Product(s);

         (b) assistance in identifying and verifying the causes of suspected
errors in the Products(s);

         (c) providing workarounds for identified Product errors or malfunctions
as set forth in sections 2.2 and 2.3 below; and

         (d) support provided under DoubleClick's policies set forth on Schedule
2 attached hereto.

         Licensee will designate the number of persons set forth in Schedule 1
to act as support liaisons to utilize the support and will ensure that such
person will be properly trained in the operation and usage of the Products. Upon
request, Licensee will allow the use of on-line diagnostics of the Products
during error diagnosis.

2.2 Error Corrections. Upon DoubleClick's receipt of written notification from
Licensee that there is any defect or error in the Products, DoubleClick shall
use commercially reasonable efforts to reproduce such defect or error as soon as
reasonably practicable. If DoubleClick is so able to reproduce such defect or
error, then DoubleClick
<PAGE>   11
shall provide commercially reasonable assistance to correct such defect or error
according to the timeframes set forth in Schedule 2. DoubleClick shall have no
obligation to correct all errors in the Product other than as set forth herein.
Upon identification of any error, Licensee shall notify DoubleClick of such
error and shall provide DoubleClick with enough information to reproduce the
error. Forthwith upon such correction being completed DoubleClick shall deliver
to Licensee documentation describing generally the nature of the correction and
providing instructions for the proper use of the corrected version of the
Products.

2.3 Error Corrections. DoubleClick shall not be responsible for correcting any
errors on the Product that are not reproduceable by either party or errors to
the extent caused by: (i) Licensee's failure to implement all Updates issued
under this Agreement; (ii) changes to the operating system or environment not
supported by DoubleClick which adversely affect the Product (it being understood
that DoubleClick is not, as of the date of this Agreement, supporting any
operating system or environment); (iii) any alterations of or additions to the
Product made by parties other than DoubleClick or other parties expressly
consented in writing by DoubleClick; (iv) use of the Product in a manner for
which it was not designed; (v) interconnection of the Product with other
software that does not meet the specifications for the Products contained in the
Products' documentation or (vi) use of the Product on an unsupported platform.

2.4 On-site Training and Support. Upon request, and provided that Licensee is
current with fees due under this Agreement, DoubleClick will provide training
for Licensee's administrators and trainers and/or direct support at Licensee's
site at DoubleClick's then applicable standard training rates and charges.

2.5 Versions Supported. DoubleClick shall be obligated to support the then
current production version of the Product and the immediately prior release for
a period of three (3) months after such new release. Support for any earlier
versions or for errors not covered under this Agreement may be obtained at
DoubleClick's then current rates.

                                    SECTION 3
                            MAINTENANCE SUBSCRIPTION

3.1 DoubleClick will provide each Update and Upgrade to Licensee promptly after
they become available when and as they become available ("Subscription"). In
reasonable time prior to the delivery of a new release, DoubleClick shall make
available to Licensee all amendments to the Software's specification which shall
describe the facilities and functions of the new release. Licensee may acquire
additional copies of the documentation at DoubleClick's then current standard
rates.

3.2 DoubleClick agrees to make available to Licensee the option to enroll as a
registrant under its Source Code Escrow Agreement. The conditions for release of
source code shall be limited to (i) DoubleClick's material breach of its
obligations under this Software Maintenance and Support Agreement which remains

to begin to cure or fails to continue to diligently pursue cure within such
thirty (30) day period; (ii) DoubleClick ceases to do business in the ordinary
course for a period of sixty (60) days or more; or (iii) the institution by or

advance the annual technical Support fee in the amount set forth in Schedule 1
for the first year following the earlier of: (a) the date that Licensee requests

time effective at the commencement of the next renewal term by giving Licensee
at least sixty (60) days' prior written notice of such change and such increase
shall be no greater than six percent (6%) over the immediate previous year's
fees. DoubleClick reserves the right to charge Licensee a reinstatement fee to
resume services if Licensee has not continuously maintained this Agreement in
effect. Annual fees on any additional units licensed beyond the initial license
will be prorated and billed at the time of the applicable license grant.

4.2 Payment. Any amount payable to DoubleClick under this Agreement will be due
and payable within thirty (30) days after Licensee's receipt of DoubleClick's

due under this Agreement to DoubleClick at the address indicated at the
beginning of this Agreement or such other location as DoubleClick designated in
writing. Any amount not paid when due will bear interest at the rate of one and
one-half percent (1.5%) per month or the maximum rate permitted by applicable
usury law, which is less, determined and compounded on a daily basis from the
date due until the date paid.

4.3 Taxes. Unless otherwise specified, the fees, charges and other amounts

5.1 Term. The term of this Agreement shall begin as of the date of DoubleClick's
signature below and continue for three (3) years thereafter, unless Licensee
notifies DoubleClick of its intention to terminate this Agreement at least
thirty (30) days prior to the effective date of the termination. In the event
that DoubleClick terminates the License Agreement pursuant to Section 7.1
thereof, DoubleClick shall refund a pro rata portion of the support and
subscription fees paid hereunder as provided in such Section 7.1.

5.2 Termination For Default. If either party defaults in the performance of or
compliance with any of its material obligations under this Agreement, and such
default has not been remedied or cured within thirty (30) days after written
notice specifying the default or, if the nature of the default is such that more
than thirty (30) days are required for the cure thereof, the defaulting party
fails to commence its efforts to cure such breach or default within such thirty
(30) day period and to diligently prosecute the same to completion thereafter,
then the nondefaulting party may terminate this Agreement in addition to its
other rights and remedies under law.

5.3 Survival. Sections 4.2, 4.3, 5, 6 and 7 shall survive the termination of
this Agreement.

                                    SECTION 6
