                                LICENSE AGREEMENT


        This LICENSE AGREEMENT (the "Agreement") is entered into as of
February 1, 1999 (the "Effective Date") by and between Netscape
Communications Corporation, a Delaware corporation having its principal
office at 501 East Middlefield Road, Mountain View, California 94043
("NETSCAPE"), and IMGIS, INC., a California corporation doing business as
"AdForce" and having its principal office at 10101 N. DeAnza Boulevard, Suite
210, Cupertino, California 95014 ("ADFORCE").


                                   WITNESSETH:


        WHEREAS, the parties hereto wish to provide the terms and conditions
under which ADFORCE will supply NETSCAPE Ad Serving Services (as defined
below) for the term provided herein; and

        WHEREAS, NETSCAPE desires to obtain, and ADFORCE is willing to grant
to NETSCAPE at the times and on the specific conditions stated herein, a
worldwide, perpetual and nonexclusive license to use, and to serve interactive
advertisements using, ADFORCE's ad serving, trafficking, targeting and related
technology on the terms and subject to the conditions set forth herein.

        NOW, THEREFORE, in consideration of the foregoing, of the mutual
covenants and undertakings contained herein and of other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
the Parties, intending to be legally bound, hereby agree as follows:


                                   ARTICLE 1
                                  DEFINITIONS

        In addition to other terms defined elsewhere herein, the following
terms will have the following meanings when used herein (any term defined in
the singular will have the same meaning when used in the plural and vice
versa, unless stated otherwise):

        1.1 "AD SERVING SERVICES" has the meaning set forth in Section 6.1
below.

        1.2 "AFFILIATE" of any specified Person means any other Person that
directly, or indirectly through one or more intermediaries, controls, is
controlled by, or is under common control with the specified Person.

that would in turn give such site the right to impressions on other sites
within that banner exchange network. Typically, such sites receive one
impression on the banner exchange network for every two they give, with the
balance available for the banner exchange network to sell to advertisers. The
program is targeted at small sites with low-value inventory which are not

ADFORCE. Examples of banner exchange networks include LinkExchange, SmartAge
and Hyperbanner.

election of members of the Board of Directors or similar governing body of
such Person; provided, however, that such Person shall cease to be a NETSCAPE
Affiliate if and when such equity interest becomes less than twenty-five
percent (25%) for any reason other than as a result of dilution, and
provided, further, that if such equity interest becomes less than twenty-five
percent (25%) as a result of dilution, such Person shall cease to be a
NETSCAPE Affiliate if and when such percentage equity interest is further
reduced for any reason other than as a result of dilution.

        1.5  "COVERED NETSCAPE PARTNER SITE PAGES" means the interactive site
pages of a NETSCAPE Partner provided that: (a) such site pages are marketed
or promoted, and intended to be accessible, to Netcenter visitors only,
meaning links to such Site Pages are available only through Netcenter and not

to serve and to sell the advertising inventory for such site.

                                GRANT OF LICENSE

    2.1  LICENSE GRANT.

         (a)  Subject to the terms and conditions hereof, and effective upon
completion by NETSCAPE of its pending merger (the "AOL Merger") with a
wholly-owned subsidiary of America Online, Inc., ADFORCE grants to NETSCAPE
a perpetual, worldwide, nonexclusive, nontransferable (except as set forth in
Section 15.12 below), royalty-free license under all of ADFORCE's patent,
copyright, trade secret and other proprietary rights to use, reproduce,
adapt, transmit, perform, display and otherwise practice the Technology or
any part thereof, other than commercially available Third Party software that
ADFORCE has the right to provide to NETSCAPE only upon payment of a fee to
the Third Party, solely for the Permitted Purposes. If for any reason the AOL
Merger is affirmatively canceled or does not otherwise occur within six (6)
months from the date hereof, then the license grants set forth herein and the
provisions set forth in Articles 3 and 4.1 and 4.2 below shall be null and
void, and NETSCAPE shall have no license rights whatsoever to the Technology.
In such event, within sixty (60) days from the earlier of (i) the date the
AOL Merger is affirmatively canceled or (ii) August 1, 1999, NETSCAPE and
ADFORCE will enter into a source code escrow agreement in form and substance
mutually acceptable to the parties. Under such agreement, ADFORCE will
deposit the source and object code for the Technology into an escrow with a
third party escrow company acceptable to the Parties. Such source code escrow
agreement will provide for the release of the source and object code to
NETSCAPE if ADFORCE ceases to do business, undergoes a bankruptcy or
insolvency proceeding, makes an assignment for the benefit of creditors or
experiences similar occurrences. In the event of a critical failure as
described in Section 4.3 below, such source code escrow agreement will
provide for the temporary release of the source and object code to NETSCAPE
for the duration of such critical failure. If ADFORCE breaches this
Agreement, the source code escrow agreement will provide for the release of
the source and object code to NETSCAPE, which NETSCAPE will then be able to
use for a period of one year from the date of such breach, after which period
NETSCAPE shall have no further rights of use. For purposes of this section
only, in order to be in breach of the Performance Metrics of Exhibit A,
ADFORCE must be in breach of at least 2 of the 4 Performance Metrics
described in Exhibit A, including at least one of either Exhibit A, Section
7(A) or 7(B).

         (b)  Subject to subsection 2.1(a) above, if any Technology consists
of commercially available Third Party software that ADFORCE has the right to
provide to NETSCAPE only upon payment of a fee to the Third Party, NETSCAPE
may, by written notice to ADFORCE and payment of such fee, require ADFORCE to
grant to NETSCAPE a perpetual, worldwide, nonexclusive, nontransferable
(except as set forth in Section 15.12 below), royalty-free (except for such
fee) license under all applicable patent, copyright, trade secret and other
proprietary rights to use, reproduce, adapt, transmit perform, display and
otherwise practice such Technology or any part thereof solely for the
Permitted Purposes (but only to the extent of ADFORCE's rights in such
Technology).

         (c)  The Parties agree that neither the licenses to be granted in
this Section 2.1 nor any other provisions of this Agreement impose or shall
be construed to impose any obligation upon NETSCAPE to use or otherwise
practice the Technology. ADFORCE agrees that it shall not bring any action in
law or equity, or any other judicial or nonjudicial proceeding, against
NETSCAPE asserting that the use by NETSCAPE of any patent rights claiming the
Technology that are now or hereafter owned by or licensed to ADFORCE or any
other Technology infringes or otherwise violates any patent, copyright, trade
secret or other proprietary rights of ADFORCE.

    2.2  EXERCISE OF RIGHTS. Following effectiveness of the licenses to be
granted herein pursuant to Section 2.1(a) above, NETSCAPE may exercise its
rights in and to the Technology at any location, on any hardware, and with
respect to all, none or any portion or combination of the Technology.
Notwithstanding the foregoing, any proposed exercise by NETSCAPE of such
rights shall be subject to the provisions of Section 15.2 below. Except as
set forth in Section 6.1 below, nothing in this Agreement shall obligate
NETSCAPE to use the Technology or to use a designated server or site in
connection with such Technology.

    2.3  USE OF PERSONNEL. NETSCAPE may exercise its rights hereunder through
Personnel who are obligated by written agreement to maintain the Technology
in confidence and restrict their use of the Technology pursuant to terms
comparable to those set forth in Article 13.

    3.1  INITIAL DELIVERY. Provided the license becomes effective per

or other information or materials.

         (b)  Provided the license becomes effective per Section 2.1(a)
above, at such times as reasonably requested by NETSCAPE, ADFORCE shall

requested by NETSCAPE that is existing and not then in the possession of
NETSCAPE. In addition, provided the license becomes effective per Section
2.1(a) above and commencing no later than forty-five (45) days after such
time that NETSCAPE determines to deploy the Technology in whole or in part
(the "Deployment Date"), ADFORCE shall provide to NETSCAPE on a quarterly
basis the then current version of the source code for the Software and shall
provide to NETSCAPE any and all Improvements, including upgrades, updates,
enhancements, patches and "bug" fixes, prior to or concurrently with their
installation or release, by any means requested by NETSCAPE (including
electronically), along with the applicable documentation related to such
Improvement.

         (c)  Provided the license becomes effective per Section 2.1(a)
above, ADFORCE shall provide all Improvements and other Technology, other
than Improvements provided in the provision of Development Services, to
NETSCAPE without any additional charge or fee. Notwithstanding the foregoing,
(i) if the license becomes effective under Section 2.1(a) above, but the
Parties have not executed a Demographic Data Agreement, or (ii) if the
license becomes effective under Section 2.1(a) above and the Parties have
executed a Demographic Data Agreement but NETSCAPE ceases to be in compliance
with all of its material obligations under the Demographic Data Agreement or
Materially Limits or Prohibits the use by ADFORCE of Demographic Data, and
NETSCAPE desires to continue receiving Improvements from ADFORCE, then
NETSCAPE shall pay to ADFORCE on an annual basis a reasonable update fee to
be agreed upon by the Parties for all Improvements developed for so long as
NETSCAPE is not in compliance with all of its material obligations under the
Demographic Data Agreement or Materially Limits or Prohibits the use by
ADFORCE of Demographic Data; provided that such fee shall not exceed (i)
ADFORCE's customary update fees for such Improvements in arm's length
transactions with its licensees, if ADFORCE then licenses the Technology to
Third Parties, or (ii) update fees charged by other licensors of comparable
systems for serving, trafficking and/or targeting of advertisements or other
information or materials, but not less than ADFORCE's cost of providing such
Improvements, if ADFORCE does not then license the Technology to Third
Parties.

         (d)  Provided the license becomes effective per Section 2.1(a) above,
at NETSCAPE's request, ADFORCE shall identify to NETSCAPE, and provide
NETSCAPE reasonable information and assistance in furtherance of NETSCAPE's
efforts to acquire, at NETSCAPE's own expense, commercially available Third
Party software licensed to ADFORCE for use in connection with the Technology
and not sublicensed to NETSCAPE under Section 2.1(a) or (b) above.

          (a)  Subject to subsection 4.2(b) below, provided that at the time
any Technical Support Services are requested by NETSCAPE or are to be

NETSCAPE shall pay to ADFORCE the Fully Burdened Costs of the provision by
ADFORCE Personnel of such Technical Support Services plus twenty-five percent
(25%) of such costs.

     4.3  WARRANTY.  If the Technology or Services as described in Exhibit A
fail to conform to or perform in accordance with the technical or user
documentation provided by ADFORCE (other than as a result of operator error,
accident, or misuse or alteration of the Technology by a Person not under
ADFORCE's direction or control), or in the event of a breach of the
warranties set forth in Section 10.2(e) or 10.2(f) below, then ADFORCE, at
its expense and without any payment by NETSCAPE for Technical Support or
other Services, shall use commercially reasonable efforts to cure such
failure or breach as soon as practicable, but in any event:

          (a)  For a "critical" failure or breach, such as the Technology, or
               other software, hardware or other technology with which the
               Technology is interfacing or integrating, ceasing to execute a
               function that NETSCAPE reasonably deems critical to its
               business, ADFORCE shall provide at least a temporary
               workaround or fix within two (2) hours of receiving notice of
               such failure or breach and shall cure such failure or breach
               within three (3) business days of receiving notice of such
               failure or breach; and

          (b)  For any other failure or breach that is not a "critical"
               problem, ADFORCE shall provide at least a temporary workaround
               or fix within three (3) business days of receiving notice of
               such failure or breach and shall cure such failure or breach
               within fifteen (15) days after receiving notice of such
               failure or breach.

Without limiting the generality of the foregoing, ADFORCE agrees, by way of
example, that it shall not be unreasonable for NETSCAPE to deem a failure or
breach "critical to its business" as provided in subpart (a) above if such
failure or breach results or would result in the breach or nonperformance by
NETSCAPE of any obligation to any advertiser on the NETSCAPE Network.

subject to the provisions of Section 2.3 above.

          5.2  FEES FOR DEVELOPMENT SERVICES.

               (a)  Provided that, at the time any Development Services are
requested to be performed by ADFORCE hereunder, NETSCAPE is in compliance
with all of its material obligations under a validly executed Demographic
Data Agreement and does not Materially Limit or Prohibit the use by ADFORCE
of Demographic Data, ADFORCE shall provide the Development Services requested
by NETSCAPE for no additional consideration other than reimbursement of the
Fully Burdened Costs of the provision by ADFORCE Personnel of such
Development Services.

               (b)  If, at any time prior to July 15, 1999 any Development
Services are requested to be performed by ADFORCE hereunder and (i) the
parties have not executed a Demographic Data Agreement, or (ii) the
Implementation Date has not yet occurred under a validly executed Demographic
Data Agreement, then NETSCAPE shall pay to ADFORCE the Fully Burdened Costs
of the provision by ADFORCE Personnel of such Development Services plus
twenty-five percent (25%) of such costs. If, at any time on or after July 15,
1999 any Development Services are required to be performed by ADFORCE

or (ii) the Implementation Date has not yet occurred under a validly executed
Demographic Data Agreement, then NETSCAPE shall pay to ADFORCE the Fully

Development Services ARE requested to be performed by ADFORCE, NETSCAPE is
not in compliance with all of its material obligations under the Demographic
Data Agreement or Materially Limits or Prohibits the use by ADFORCE of
Demographic Data, then NETSCAPE shall pay to ADFORCE the Fully Burdened Costs
of the provision by ADFORCE Personnel of such Development Services plus
twenty-five percent (25%) of such costs.

          5.3  ORIGINAL WORK.  Any Work Products either shall be the original
work of ADFORCE and its Personnel or shall be items licensed by Third Parties
that ADFORCE has the right to provide to NETSCAPE and that ADFORCE identifies
as such to NETSCAPE in writing. ADFORCE shall not disclose to NETSCAPE, or
induce NETSCAPE to use, the trade secrets or other confidential information
of any Third Parties, except to the extent that the Technology includes
Software licensed from Third Parties which ADFORCE has the right to provide
to NETSCAPE.

          (a)  The Parties intend that each Work Product that is a work of
authorship shall be deemed a "work made for hire" within the meaning of the
copyright laws of the United States and any similar laws of other
jurisdictions. To the extent, if any, that ADFORCE or its Personnel have
rights in any Work Product notwithstanding the foregoing, including because a
Work Product does not qualify as a "work made for hire," ADFORCE hereby
irrevocably assigns to NETSCAPE, and agrees that NETSCAPE shall be the sole
and exclusive owner of, all right, title and interest in and to the Work
Product, including all patent, copyright, trade secret and other proprietary
rights therein that may be secured in any place under laws now or hereafter
in effect.

          (b)  To extent that ADFORCE provides Development Services in support
of any modification of the Technology, NETSCAPE hereby grants to ADFORCE a
perpetual, worldwide, nonexclusive, nontransferable license to use,
reproduce, adapt, transmit, perform and display such modification in
connection with the provision of such Development Services and for no other
purpose without NETSCAPE's prior written approval. In the event that ADFORCE
desires to integrate such modification in the Technology and obtains
NETSCAPE's approval thereto, then ADFORCE shall reimburse NETSCAPE for any
payment made by NETSCAPE for such Development Services, or waive such payment
by NETSCAPE, in consideration for the grant of such license to ADFORCE.
ADFORCE may exercise its rights under the foregoing license through Personnel
who are obligated by written agreement to maintain such modification in
confidence and restrict their use of such modification pursuant to terms
comparable to those set forth in Article 13.

          (c)  ADFORCE shall have valid and enforceable written agreements
with all of its Personnel providing Development Services hereunder containing
confidentiality and nondisclosure obligations comparable in scope to those
set forth in Article 13 and giving ADFORCE all rights and authority necessary
to effectuate the provisions of this Section 5.4.  ADFORCE shall provide
copies of these agreements to NETSCAPE upon NETSCAPE's request.

          (d)  To the extent that ADFORCE delivers to NETSCAPE any
Improvements, designs, drawings, specifications, documentation, computer
software, reports, training materials, inventions, discoveries and other
items that are not Work Products, such items shall be deemed included in the
Technology and licensed pursuant to Section 2.1 above.

      5.5  CHANGE MANAGEMENT PROCESS.  Notwithstanding the foregoing
provisions of this Article 5, if NETSCAPE implements a version of the
Technology containing any modification to the source code for the Software
that adds a substantially new feature or function to the version of the
Technology used by ADFORCE (in contrast to merely correcting what are
colloquially known as "bugs" in such Software or making any other minor
modification to an existing feature or function) then: (a) ADFORCE shall not
be obligated to provide Development Services or Technical Support Services
for such Improvement; and (b) in the event that NETSCAPE does not request, or
ADFORCE does

not agree to provide, such Services, the Parties shall work together to
devise a change management process to facilitate the technical support and

                               AD SERVING SERVICES

      6.1  SCOPE OF SERVICES.  From the Effective Date through November 22,
1999 (the "initial Ad Serving Services Term"), ADFORCE shall provide to
NETSCAPE interactive advertisement serving, trafficking, targeting and
related services (collectively, "Ad Serving Services") for NETSCAPE
Netcenter, and such other parts of the NETSCAPE Network as NETSCAPE shall
reasonably request. The terms for such Ad Serving Services shall be as attached
hereto in Exhibits A and B and as set forth below.

      6.2  FEES FOR AD SERVING SERVICES.

           (a)  Provided that, at the time any Ad Serving Services are to be
performed by ADFORCE, NETSCAPE is in compliance with all of its material
obligations under a validly executed Demographic Data Agreement and does not
Materially Limit or Prohibit the use by ADFORCE of Demographic Data, ADFORCE
shall provide the Ad Serving Services requested by NETSCAPE for no additional
consideration other than reimbursement of the Fully Burdened Costs of the
provision by ADFORCE Personnel of such Ad Serving Services; provided,
however, that in the event that ADFORCE agrees to provide any Ad Serving
Services to any Third Party that is similarly situated to NETSCAPE at a rate
that is more favorable to such Third Party than the consideration payable
by NETSCAPE under this subpart (a), then ADFORCE shall provide the Ad Serving
Services requested by NETSCAPE at such Third Party's rate.

Implementation Date has not yet occurred under a validly executed Demographic
Data Agreement, then NETSCAPE shall pay to ADFORCE the Fully Burdened Costs
of the provision by ADFORCE Personnel of such Ad Serving Services plus forty
percent (40%) of such costs.

          (c)  If, following the occurrence of the Implementation Date under

Prohibits the use by ADFORCE of Demographic Data, then NETSCAPE shall pay to
ADFORCE the Fully Burdened Costs of the provision by ADFORCE Personnel of such
Ad Serving Services plus twenty-five percent (25%) of such costs.

     6.3  REIMBURSEMENT FOR AD SERVING SERVICES.  In addition to the fees for Ad
Serving Services provided for in Section 6.2 above, NETSCAPE shall reimburse the
following costs incurred by ADFORCE in the provision of Ad Serving Services
requested by NETSCAPE for the purposes set forth in Section 6.1 above, and, at
NETSCAPE'S option, NETSCAPE shall provide financing for such costs on mutually
agreeable terms, but in any event on terms no less favorable than such terms are
commercially available to entities similarly situated.

          (a)  Reimbursement for ADFORCE's incremental costs for any
               modification of the AdForce System required to meet NETSCAPE's
               needs for the provision of Ad Serving Services (other than
               capitalized costs, which if financed at the time such costs are
               incurred, shall be reimbursed at the time such costs are
               amortized), excluding any modifications required to scale the
               Software or other Technology to meet NETSCAPE's needs;

          (b)  Reimbursement for ADFORCE'S incremental costs for any additional
               equipment that ADFORCE must purchase or lease solely to meet
               NETSCAPE's needs for the provision of Ad Serving Services for so
               long as necessary to meet NETSCAPE's needs; and

          (c)  Reimbursement for any additional incremental bandwith costs
               incurred by ADFORCE solely in connection with the provision of Ad
               Serving Services to NETSCAPE.

     6.4  APPLICATION OF FEE METHODOLOGY.  Attached hereto as Exhibit B is the
Parties' agreed upon pricing for the Ad Serving Services for the Initial Ad
Services Term per the provisions of Sections 6.2 and 6.3 above.

                              NETSCAPE MARKETING EFFORTS

     7.1  NETSCAPE MARKETING EFFORTS.  NETSCAPE shall use commercially
reasonable efforts to encourage NETSCAPE Partners (but NETSCAPE shall not be
obligated to actively solicit NETSCAPE Partners) to use the AdForce System for
the serving and management of Internet advertisements, subject to agreement
between ADFORCE and such NETSCAPE Partners on the terms and conditions of such
use.

     7.2  COMMISSIONS.  If, as a result of marketing efforts by NETSCAPE, a
NETSCAPE Partner or any other Person enters into an agreement with ADFORCE to


                                          14

                                                                  CONFIDENTIAL

utilize the AdForce System, then, provided that, as of the time that ADFORCE
enters into such agreement with such NETSCAPE Partner or other Person, the
Parties have executed a Demographic Data Agreement, NETSCAPE is in compliance
with all of its material obligations thereunder and does not Materially Limit or
Prohibit the use by ADFORCE of Demographic Data, ADFORCE shall pay to NETSCAPE
on a quarterly basis the following commissions on the gross amount of the
consideration charged by ADFORCE to such NETSCAPE Partner or other Person for
use of the ADFORCE AdForce System:

          (a)  For the first year of such agreement, the greater of 4% and the
               highest percentage commission granted by ADFORCE at such time to
               any employee or agent of ADFORCE or to any Third Party for
               similar marketing or sales efforts; and

          (b)  For each succeeding year of such agreement, the greater of 2% and
               the highest percentage commission granted by ADFORCE at such
               time to any employee or agent of ADFORCE or to any Third Party
               for similar marketing or sales efforts.

     7.3  COMMISSION SHARING.  Notwithstanding the provisions of Section 7.2
above, if NETSCAPE and any employee or agent of ADFORCE or any other Third Party
claims commissions with respect to the same Person (and such Person has not
entered into an agreement with ADFORCE solely as a result of NETSCAPE marketing
efforts), ADFORCE shall not be required to pay total commissions to NETSCAPE and
such Third Party in excess of the amount specified in Section 7.2 and ADFORCE
may apportion the applicable commission specified in Section 7.2 between
NETSCAPE and the Third Party in such manner as ADFORCE determines in good faith
to be equitable.

                                  PAYMENT PROVISIONS

     9.1  PAYMENT PROCEDURES.

          (a)  Unless otherwise agreed to in writing by the Parties, all
payments due by NETSCAPE for the provision of Services by ADFORCE hereunder
shall be due and payable thirty (30) days after the receipt by NETSCAPE of a
proper invoice therefor from ADFORCE, which invoice shall include such detail
and supporting documentation as NETSCAPE may reasonably request. Notwithstanding
the foregoing, NETSCAPE agrees to pay to ADFORCE the amount set forth in Exhibit
B within forty-five (45) days from the


                                          15

                                                                  CONFIDENTIAL

Effective Date, which represents a prepayment of the estimated fees for Ad
Serving Services for the Initial Ad Serving Services Term ("Prepayment").

The Prepayment shall be credited against the Ad Serving Service fees accruing
under this Agreement during the Initial Term, which ADFORCE shall calculate
monthly in accordance with Exhibits B and C and submit to NETSCAPE for its
review and approval.  For each $1.00 of fees due up to the Prepayment, $1.00
shall be credited against the Prepayment.  Upon exhaustion of the Prepayment,
ADFORCE shall invoice NETSCAPE monthly in arrears for the Ad Serving Services
provided to NETSCAPE based on the rates for such Services as set forth in
Exhibit B.

Each month and coincident with the impression forecast NETSCAPE will provide per
Exhibit A, Section 1(C), the Parties will review the estimates that form the
basis of the prepayment described in Exhibit B and discuss any adjustments to
the forecast, principally the impression forecast and the headcount forecast.
Unless the parties mutually agree otherwise, if the changes to the forecasts in
Exhibit C are estimated to have a sum total impact greater than 10% on the fees
(as measured against the prior adjustment to fees), the Parties will make a
mutually agreed to adjustment in the fees going forward.

On or before August 1, 1999, the Parties will evaluate if there is a significant
change in the payment forecast for the remainder of the term.  If there is a
significant decline in the forecast (greater than 30%), ADFORCE will make an
adjusting refund at that time, including interest on the amount of the refund
equal to the lower of (i) the prime rate on August 1, 1999 or (ii) the maximum
amount permitted by law.

If Netscape opts to deploy ADFORCE's Banner Exchange technology to provide a
Banner Exchange to NETSCAPE Banner Exchange Partner sites outside of NETSCAPE
Netcenter or NETSCAPE Affiliates, NETSCAPE may do so solely on a "barter" basis
as described in the Banner Exchange definition above.  For ads served by
NETSCAPE to such external sites, NETSCAPE will make additional payments to
ADFORCE based on a CPM rate equal to 50% of NETSCAPE's imputed CPM at the end of
the Initial Term or a $0.04 CPM, whichever is higher, provided that the rate
shall never exceed the lowest CPM rate ADFORCE is offering other banner exchange
customers.  NETSCAPE shall make these payments for as long as it requests the
delivery of improvements to ADFORCE's Banner Exchange technology or a minimum of
two years after NETSCAPE first deploys ADFORCE's Banner Exchange technology,
whichever is greater.

          (b)  Unless otherwise agreed to in writing by the Parties:  (i) all
payments due by ADFORCE under Article 7 in connection with ADFORCE's entrance
into an agreement for use of the AdForce System with an NETSCAPE Partner or
other Person as a result of NETSCAPE marketing efforts shall be paid to
NETSCAPE within sixty (60) days after the end of the calendar quarter during
which such agreement is entered into and within sixty (60) days after the end
of each succeeding calendar quarter thereafter.

          (c)  All payments due to the payee Party hereunder shall be paid to
the payee Party in U.S. Dollars by wire transfer, or by such other method
mutually agreed upon by the Parties, in each case at the expense of the payor
Party, for value no later than the due date thereof (with 24 hours advance
notice of each wire transfer) to such bank account or accounts as the payee
Party shall designate in writing within a reasonable period of time prior to
such due date.

     9.2  LATE PAYMENT.  Without limiting the payee Party's rights to pursue any
other remedies at law or in equity, if the payor Party fails to pay any payment
required under this Agreement thirty days after written notice of past due
amount, then the payor Party shall pay annually compounded interest on such
amount at an annual rate equal to the lower of (a) the highest rate permitted by
applicable law and (b) the lowest prime rate as published by The Wall Street
Journal on or nearest to such due date plus three percent (3%), which interest
shall accrue from the date the payment not timely made became due until the date
such payment is paid in full.

     9.3  APPLICATION OF PAYMENTS.  Any payments received by the payee Party
shall be applied first to the satisfaction of the oldest of any unpaid, accrued
interest charges and, following payment of all such interest charges, to the
satisfaction of the oldest of any unpaid fees or other amounts due hereunder.

     9.4  TAXES.

          (a)  All payments required to be made by the payor Party under this
Agreement shall be made free and clear of, and without deduction for, any and
all taxes that are levied on the transfer of such payments to the payee Party.
If any withholding or deductions are required by applicable law, payments shall
be made such that, after such withholding or deductions, the net amount that the
payee Party received is equal to the amount due hereunder.  The payor Party
shall file any information or tax returns with respect to such taxes, and the
payor Party shall indemnify the payee Party from any interest or other payments,
fines or penalties relating to or resulting from any failure, delay or error of
the payor Party in doing so.

          (b)  ADFORCE shall be responsible for the payment of any and all
transfer, sales, use or similar taxes that are levied on or in connection with
the transfer of the Technology to NETSCAPE, including any Improvements.

     9.5  BOOKS AND RECORDS.  ADFORCE shall keep full, true and accurate books
of account containing all particulars and reasonable supporting documentation,
in connection with the provision of Services hereunder and the determination of
any amounts payable to NETSCAPE under Article 7.  All such books of account and
reasonable supporting documentation shall be located at the principal place of
business of ADFORCE and shall be open for inspection by NETSCAPE or any
independent certified public accountant retained by NETSCAPE, at a time mutually
acceptable to the Parties during normal business hours but no more frequently
than once each calendar year for three years

following the end of the calendar year to which they pertain (and access shall
not be denied thereafter if reasonably available).  If such records are
insufficient or any such inspection discloses a discrepancy in favor of NETSCAPE
of five percent (5%) or more of the amounts actually due for any period, then,
in addition to any other rights and remedies available to NETSCAPE under this
Agreement, ADFORCE shall pay or refund to NETSCAPE the amount of such
discrepancy as well as the reasonable cost of such inspection promptly following
ADFORCE's receipt from NETSCAPE of the bill or invoice for such inspection.

               accordance with its terms, except as enforcement may be limited
               by general principles of equity (regardless of whether such
               enforceability is considered in a proceeding at law or in equity)
               and the effect of applicable bankruptcy, insolvency, moratorium
               and other similar laws of general application relating to or

          (e)  No consent, approval or authorization of or from any governmental
               entity or any other Person not a Party to this Agreement, whether
               prescribed by law, regulation, contract or agreement, is required
               for such Party's execution, delivery and performance of this
               Agreement or consummation of the transactions contemplated
               hereby.

     10.2  ADDITIONAL REPRESENTATIONS AND WARRANTIES OF ADFORCE. ADFORCE
further represents and warrants to NETSCAPE that:

           (a)  WORKMANLIKE SERVICES. The Services shall be provided in a
                workmanlike manner, in accordance with the standards of care
                and diligence and the level of skill, knowledge and judgment
                normally practiced by nationally-recognized information
                technology services firms in performing services of a similar
                nature;

           (b)  NONINFRINGEMENT.  The Technology does not, and any
                Improvements provided by ADFORCE, any Work Products and
                NETSCAPE's use of the Technology and Work Products as
                authorized herein shall not, infringe any copyright, trade
                secret or other proprietary rights (except patent rights) of
                any Third Party or otherwise conflict with the rights of any
                Third Party, and, to the best of ADFORCES's knowledge, the
                Technology does not, and any Improvements provided by
                ADFORCE, any Work Products and NETSCAPE's use of the
                Technology and Work Products shall not, infringe any patent
                of any Third Party;

           (c)  NO LITIGATION.  There is no action, suit, proceeding or
                arbitration pending, and, to the best of ADFORCE's knowledge,
                there is no action, suit, proceeding, arbitration or claim
                threatened, concerning the Technology;

           (d)  NO LIENS OR ENCUMBRANCES.  The Technology is free from any
                security interests and other liens and encumbrances of Third
                Parties arising from the actions or inaction of ADFORCE;

           (e)  NO UNAUTHORIZED CODE.  The Technology does not, and any
                Improvements provided by ADFORCE shall not, contain any back
                door, time bomb, drop dead device, protect codes, data
                destruct keys, or other software routine designed to disable
                a computer program automatically with the passage of time or
                under the control of any Person other than NETSCAPE. To the
                best of ADFORCE's knowledge, the Technology does not, and any
                Improvements provided by ADFORCE shall not, contain any
                virus, Trojan horse, worm or other software routine designed
                to permit unauthorized access or to disable, erase, modify,
                deactivate or otherwise harm software, hardware or data; and
                ADFORCE covenants that, prior to or at the time of the
                delivery of any Technology (including any Improvement),
                ADFORCE shall test the Technology using a current version of
                a reputable "antivirus" program and remove any such
                unauthorized codes; and

                                                                  CONFIDENTIAL

           (f)  YEAR 2000 COMPLIANCE.  All Software and other operational
                items included in the Technology shall: (i) properly execute
                with all date data, whether from years in the same century or
                different centuries, including by yielding correct results
                in arithmetic operations, comparisons and sorting of date
                fields and in leap year calculations; and (ii) not abnormally
                cease to execute or return an error message due to
                date-related processing.

     10.3  NO OTHER WARRANTIES.  THE EXPRESS WARRANTIES IN THIS AGREEMENT
SHALL BE IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

                               ARTICLE 11
                            INDEMNIFICATION

     11.1  INDEMNITY.  NETSCAPE shall not be liable to ADFORCE, any of its
Affiliates or any other Person for, and ADFORCE shall indemnify and hold
harmless NETSCAPE and all NETSCAPE Affiliates, and their respective
directors, officers, employees and agents (collectively, the "NETSCAPE
Indemnitees"), from and against any Losses incurred arising out of or
resulting from: (a) any infringement of any patent, copyright, trade secret
or other proprietary right by the Technology or any Work Product, except to
the extent that such infringement arises solely from any Improvement
developed by NETSCAPE, or by ADFORCE to NETSCAPE's specifications if ADFORCE
could not reasonably have conformed to such specifications while avoiding the
infringement; or (b) the presence of ADFORCE's employees or agents on the
premises of NETSCAPE or an NETSCAPE Affiliate (except those Losses that
result solely from the gross negligence or willful misconduct of NETSCAPE or
a NETSCAPE Affiliate), including, but not limited to, Losses resulting from
injuries to ADFORCE's Personnel and Losses resulting from injuries caused by
ADFORCE's Personnel.

     11.2  PROCEDURE.  Any NETSCAPE Indemnitee shall notify ADFORCE promptly
in writing of an indemnifiable claim or cause of action under Section 11.1
above upon receiving notice or being informed of the existence thereof;
provided, however, that failure to notify ADFORCE of an indemnifiable claim
or cause of action shall not relieve ADFORCE of its obligation to provide
indemnification hereunder, except to the extent that such failure prejudices
ADFORCE's ability to defend or settle such claim or cause of action. ADFORCE
shall assume, at its cost and expense, the sole defense of such claim or cause
of action through counsel selected by ADFORCE and reasonably acceptable to
NETSCAPE, except that in the case of a conflict of interest between ADFORCE
and NETSCAPE, ADFORCE shall, at ADFORCE's cost and expense, provide separate
counsel for NETSCAPE selected by NETSCAPE. ADFORCE shall maintain control of
such defense, including any decision as to settlement; provided that, in the
event that


                                    20

<PAGE>

                                                                  CONFIDENTIAL

ADFORCE does not maintain control of such defense on a timely basis, then,
without prejudice to any other rights and remedies available to NETSCAPE
under this Agreement, NETSCAPE may take over such defense with counsel of its
choosing, at ADFORCE's cost and expense. NETSCAPE may, at its option and
expense, participate in ADFORCE's defense, and if NETSCAPE so participates,
the Parties shall cooperate with one another in such defense. ADFORCE shall
bear the total costs of any court award or any settlement of such claim or
cause of action approved by ADFORCE and all other costs, fees and expenses
related to the resolution thereof (including reasonable attorneys' fees,
except for attorneys' fees for which NETSCAPE is responsible in the event
that NETSCAPE participates in ADFORCE's defense of such claim or cause of
action).

     11.3  ABATEMENT OF INFRINGEMENT.  If ADFORCE reasonably believes it
necessary to do so to minimize its liability under Section 11.1 above,
ADFORCE may, at its expense, procure the right for NETSCAPE to continue using
the Technology or any Work Product, replace the Technology or any Work
Product with a functionally equivalent noninfringing item, or modify the
Technology or any Work Product so that it is functionally equivalent but
noninfringing.

                            ARTICLE 12
                      LIMITATION ON LIABILITY

     NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY HEREUNDER FOR ANY
INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES.

                            ARTICLE 13
                         CONFIDENTIALITY

     13.1 CONFIDENTIALITY OBLIGATION.  Each of NETSCAPE and ADFORCE (the
"Receiving Party") shall keep, and shall cause their Affiliates to keep,
strictly confidential any information disclosed by the other Party (the
"Disclosing Party") or otherwise made available to the Receiving Party
concerning the Technology or either Party's performance of this Agreement or
otherwise concerning the business, operations, trade secrets or other
proprietary information of the Disclosing Party (whether in written media or
otherwise) ("Confidential Information"), using the same degree of care that
it uses to protect its own confidential or proprietary information of a like
nature but in no event less than a reasonable degree of care.  "Confidential
Information" shall not include information: (a) which is or becomes generally
available to the public other than as a result of disclosure thereof by the
Receiving Party; (b) which is lawfully received by the Receiving Party on
a nonconfidential basis from a Third Party that is not itself under any
obligation of confidentiality or nondisclosure to the Disclosing Party or any
other Person with respect to such information; (c) which is independently
developed by the Receiving Party; or (d) which was in the Receiving Party's 
possession prior to receipt from the Disclosing Party. Each Party shall
treat any Technology or Work Product owned by or assigned to the other Party
as Confidential Information of such Party.

<PAGE>

                                                                  CONFIDENTIAL

     13.2  NONDISCLOSURE OF CONFIDENTIAL INFORMATION.  The Receiving Party
shall use Confidential Information solely for the purposes of this Agreement
and shall not disclose or disseminate any Confidential Information to any
Person at any time, except for disclosure to its Affiliates and to those of
its own and its Affiliates' directors, officers, employees, accountants,
attorneys, advisers and agents whose duties reasonably require them to have
access to such Confidential Information, provided that such directors,
officers, employees, accountants, attorneys, advisers and agents are bound
to maintain the confidentiality of such Confidential Information to the same
extent as if they were Parties hereto.

     13.3  EXCEPTION.  The foregoing confidentiality and nondisclosure
obligations shall not apply to Confidential Information: (a) incidentally
retained in the memory of Persons to whom the Receiving Party is permitted
to disclose Confidential Information, other than as the result of an
intentional effort to commit Confidential Information to memory to circumvent
the provisions of this Article 13; or (b) which is required to be publicly
disclosed by law or by regulation; provided, however, that, in such event,
the Receiving Party provides the Disclosing Party with prompt advance notice
of such disclosure so that the Disclosing Party has the opportunity if it so
desires to seek a protective order or other appropriate remedy.

     13.4  SURVIVAL.  The confidentiality and nondisclosure obligations of
this Article 13 shall remain in effect for three years following the date
hereof or two years following the termination of this Agreement, whichever is
greater, except with respect to source code and related source code
documentation, for which the obligations of this Article 13 shall survive for
so long as the source code and documentation remain Confidential Information.

     13.5  SOURCE CODE PROTECTION.  The Receiving Party shall protect
Confidential Information consisting of source code and related source code
documentation from unauthorized use and disclosure to the same extent that it
protects its own source code (but no less than to a reasonable degree).

     13.6  OTHER BUSINESS ACTIVITIES.

           (a)  The Disclosing Party agrees that the Receiving Party may
currently or in the future acquire information, either independently
developed or legally received from Third Parties, which may be similar to the
Confidential Information. Nothing in this Agreement shall be construed as a
representation that the Receiving Party does not or shall not have such
independently developed or legally received information.

           (b)  Nothing in this Agreement shall be construed as a
representation or agreement to restrict reassignment of the Receiving Party's
employees, or in any manner to affect or limit either Party's present or
future business activities of any nature, including business activities which
could be competitive with the Disclosing Party.

           (c)  Nothing in this Agreement shall be construed as a
representation or agreement that the Receiving Party shall not develop or have
developed for it products, concepts, systems or techniques contemplated by or
embodied in the Confidential Information, provided that the Receiving Party
does not violate any of its obligations under this Agreement in connection
with such development.

                              ARTICLE 14

     14.1  TERM.

           14.1.1 TECHNOLOGY LICENSE TERM.  Provided the license grant to

the provisions of Section 14.2 below, shall remain in full force and effect
without expiration.

           14.1.2 TECHNOLOGY LICENSE GRANTED BY DEFAULT TERM.  If the license
grant to NETSCAPE does not become effective pursuant to Section 2.1(a) but
Netscape obtains access to ADFORCE's source and object code as a result of
ADFORCE's default hereunder as described in such Section 2.1 (a), then this
Agreement with respect to such license grant and related provisions herein
shall commence as of the Effective Date and remain in full force and effect
through the date NETSCAPE's one-year right to use said source and object code
expires.

           14.1.3 AD SERVING SERVICES TERM.  The term of this Agreement with
respect to the Ad Serving Services and related provisions herein shall
commence as of the Effective Date and remain in full force and effect through

of this Agreement, this Agreement with respect to such Ad Serving Services
will renew on the same terms and conditions for an additional one year period.

     14.2  TERMINATION.

           14.2.1  TERMINATION RIGHTS OF NETSCAPE.  NETSCAPE shall have the
right to terminate this Agreement in the event of the breach by ADFORCE of,
or the failure of ADFORCE to perform, any of its material obligations
hereunder and the failure to remedy such breach or nonperformance with sixty
(60) days following the receipt of written notice of such breach or
nonperformance from NETSCAPE. Such termination shall be immediately effective
upon the receipt by ADFORCE of written notice of termination from NETSCAPE.
On expiration or termination of this Agreement for any reason, the parties
agree to work in good faith to ensure a smooth transition of the Service and
Technology (if applicable) to NETSCAPE within 60 days of such termination or

           14.2.2 TERMINATION RIGHTS OF ADFORCE. ADFORCE shall have the right
to terminate this Agreement in the event of:

                (a)     The breach by NETSCAPE of, or the failure of NETSCAPE
                        to perform, any of its material obligations under
                        this Agreement (except for its obligations under
                        Articles 3, 4, 5 and 6 above) and the failure to
                        remedy such breach or nonperformance within sixty
                        (60) days following the receipt of written notice of
                        such breach or nonperformance from ADFORCE; or

                (b)     A "Data Agreement Material Breach" by NETSCAPE. For
                        purposes of this Agreement, a "Data Agreement Material
                        Breach" means the breach by NETSCAPE of, or the
                        failure of NETSCAPE to perform, any of its material
                        obligations under the Demographic Data Agreement, the
                        failure of NETSCAPE to remedy such breach or
                        nonperformance within sixty (60) days following the
                        receipt of written notice of such breach or
                        nonperformance from ADFORCE, and, in the event that
                        such breach or nonperformance is disputed by the
                        Parties, the final determination of such breach or
                        nonperformance by a court of competent jurisdiction
                        from which no further appeal may be taken.

Such termination shall be immediately effective upon the receipt by NETSCAPE
of written notice of termination from ADFORCE.

           14.2.3  ADFORCE RIGHT TO DISCONTINUE SERVICES. ADFORCE shall have
the right to discontinue the provision of Services pursuant to Sections 3.2,
4.1, 5.1 and 6.1 above for which it is entitled to reimbursement or other
payment from NETSCAPE, but shall not have the right to terminate this
Agreement or the licenses granted pursuant to Section 2.1(a) above, if
effective, in the event of the material breach by NETSCAPE of its obligation
hereunder to reimburse or pay ADFORCE for any Services and the failure to
remedy such breach within sixty (60) days following the receipt of written
notice of such breach from ADFORCE. Such discontinuation of Services shall be
immediately effective upon the receipt by NETSCAPE of written notice of
discontinuation from ADFORCE. On expiration or termination of this Agreement
for any reason, the parties agree to work in good faith to ensure a smooth
transition of the Service and Technology (if applicable) to NETSCAPE within
60 days of such termination or expiration date.

     14.3  EFFECT OF TERMINATION. Provided the license grant to NETSCAPE
under Section 2.1(a) becomes effective, and notwithstanding anything herein
to the contrary, in the event of the termination of this Agreement other than
upon the breach by NETSCAPE of any of its material obligations under Article
2 or Article 13 and the failure to remedy

                                                                  CONFIDENTIAL

such breach within the time period set forth in Section 14.2.2 above,
NETSCAPE shall have the right, for a period of one year following
termination, to continue to exercise all license rights granted to it under
Section 2.1 above on all the same terms in effect pursuant to this Agreement
immediately prior to termination and to retain any Confidential Information
necessary or useful for the exercise of such rights. Notwithstanding anything
herein to the contrary, ADFORCE shall in no event be entitled to enjoin or
seek to enjoin any exercise by NETSCAPE of the rights set forth in this
Section 14.3, and ADFORCE hereby expressly waives any right to injunctive or
other equitable relief, whether based on statute, common law or otherwise,
arising out of any alleged default by NETSCAPE that would adversely affect
the exercise by NETSCAPE of its rights under this Section 14.3.

     14.4  RETURN OF CONFIDENTIAL INFORMATION. Within thirty (30)
calendar days following the termination of this Agreement other than
termination where Section 14.3 above would be applicable, each Party shall
either deliver to the other Party, or destroy, all copies of any Confidential
Information of the other Party embodied in a tangible medium that is in such
Party's possession or under its control, and shall furnish to the other Party
an affidavit signed by an officer of such Party certifying that, to the best
of its knowledge, such delivery or destruction has been fully effected.

     14.5  SURVIVAL. All rights granted to and obligations undertaken by
the Parties hereunder shall terminate immediately upon the termination of
this Agreement, except for the rights and obligations provided for in
Sections 14.3 and 14.4 above as well as the following rights and obligations,
which shall survive according to their terms:

               (a)   The obligation of the payor Party to pay any and all
                     payments accrued hereunder;

               (b)   The license to ADFORCE granted in Section 5.4;

               (c)   The right of NETSCAPE to inspect the books and records
                     of ADFORCE to the extent provided in Section 9.5;

               (d)   The indemnification obligations of Article 11 and the
                     limitation on liability of Article 12;

               (e)   The confidentiality and nondisclosure obligations of
                     Article 13; and

               (f)   The provisions of Sections 15.1, 15.7, 15.8, 15.10,
                     15.19, and 15.20 below.

In addition, termination of this Agreement shall not affect the remedies of
the Parties otherwise available at law or in equity in relation to any rights
accrued under this Agreement prior to termination.

     15.1  ELECTRONIC REPOSSESSION. In no event shall ADFORCE
electronically repossess, de-install, deactivate or disable any Technology in
the absence of a final, unappealable judgment of a court of competent
jurisdiction that the license rights granted under Section 2.1 above have
been validly terminated.

     15.2   PERIODIC DISCUSSIONS. Commencing within thirty (30) days
following the execution of this Agreement and on a quarterly basis
thereafter, NETSCAPE shall engage in discussions with ADFORCE concerning
NETSCAPE's deployment of the Technology and shall endeavor to provide ADFORCE
with non-binding, 180 day forecasts of the Services that NETSCAPE intends to
request from ADFORCE hereunder. Within forty-five (45) days after the
Deployment Date, the Parties shall execute a more detailed development,
support and maintenance agreement with respect to ADFORCE's obligations to
provide development, support and maintenance for the Technology, including,
without limitation, ADFORCE's obligations for the delivery of Improvements
and other Technology, ADFORCE's obligations to provide Development Services
and Technical Services, and ADFORCE's obligations to cure any nonperformance
or other failure with respect to the Technology.

     15.3   MUTUAL NON-SOLICITATION. For a period of one year following
the date hereof, without the prior written approval of the other Party,
neither Party or any of its Affiliates shall actively solicit for hire any
Personnel of the other Party with responsibility for the development or
maintenance of the Technology or Work Products or for the provision of
interactive advertisement serving, trafficking, targeting or related
services, excluding independent contractors that do not spend the majority of
their time providing services to such Party. The foregoing mutual
non-solicitation covenant shall terminate at any time in the event of the
acquisition by a Third Party of more than fifty percent (50%) of the voting
power of ADFORCE, the acquisition by a Third Party of all or substantially all
of the assets of ADFORCE, or the consummation of a merger, consolidation or
similar corporate transaction of ADFORCE with or into a Third Party where the
voting securities of ADFORCE outstanding immediately prior to consummation of
such transaction are converted into cash or securities possessing less than
fifty percent (50%) of the voting power of the surviving entity. The
obligations of the Parties under this Section 15.3 shall not survive the
termination of this Agreement.

     15.4   FAILURE TO ASSERT RIGHTS IN BANKRUPTCY. NETSCAPE's failure to
assert its rights to retain its benefits under this Agreement in accordance
with 11 U.S.C. Section 365(n)(1)(B) shall not be construed as a termination
of this Agreement by NETSCAPE under 11 U.S.C. Section 365(n)(1)(A).

     15.5   FURTHER ASSURANCES. Upon the request of either Party, the
other Party shall sign and deliver any assignments or other necessary
documents and otherwise assist the requesting Party to obtain, maintain,
perfect or enforce any of the requesting Party's rights hereunder.

     15.11  FORCE MAJEURE. If any circumstance beyond the reasonable
control of either Party occurs which delays or renders impossible the
performance of that Party's obligations under this Agreement on the dates
herein provided, such obligation shall be postponed for such time as such
performance necessarily has had to be suspended or delayed on account
thereof, provided such Party shall notify the other Party in writing as soon
as practicable, but in no event more than ten days after the occurrence of
such force majeure. In such event, the Parties shall meet promptly to
determine an equitable solution to the effects of any such event, provided
that such Party who fails because of force majeure to perform its obligations
hereunder shall upon the cessation of the force majeure take all reasonable
steps within its power to resume with the least possible delay compliance
with its obligations. Events of force majeure shall include, without
limitation, war, revolution, invasion, insurrection, riots, mob violence,

limitations imposed by exchange control regulations or foreign investment
regulations or similar regulations, laws, regulations or rules of any
government or governmental agency, and any inordinate and unanticipated
delays in the regulatory review or governmental approval process that are
within the control of such government or governmental agency. In no event
shall the failure or nonperformance of the Technology as described in Section
4.3 above constitute an event of force majeure.

     15.12  BINDING EFFECT; ASSIGNMENT.  This Agreement may not be
assigned, in whole or in part, by either Party without the prior written
consent of the other Party, except that: (a) NETSCAPE may assign any of its
rights or obligations hereunder to America Online, Inc. or a wholly-owned
subsidiary of NETSCAPE without ADFORCES's consent; and (b) the rights and
obligations of either Party under this Agreement may be assigned without the
other Party's consent to a Third Party acquiring all or substantially all of
the assets of the assigning Party or to the surviving entity upon the
consummation of any merger, consolidation or similar corporate transaction of
the assigning Party with or into a Third Party. Any attempted assignment by
either Party without the consent of the other Party in any circumstances
other than those described in the immediately preceding sentence shall be
null and void. This Agreement shall inure to the benefit of and be binding
upon each of the Parties hereto and their respective successors and permitted
assigns.

     15.13  ENTIRE AGREEMENT.  The terms and conditions herein contained
constitute the entire agreement between the Parties relating to the subject
matter of this Agreement and shall supersede all previous communications
between the Parties with respect to the subject matter of this Agreement,
except for the Confidential Non-Disclosure Agreement between the Parties
dated as of January 1, 1999, and attached hereto as Exhibit D, each of which
shall survive according to their terms. Neither Party has entered into this
Agreement in reliance upon any representation, warranty, covenant or
undertaking of the other Party that is not set out or referred to in this
Agreement.

     15.14  RECITALS.  The recitals set forth at the start of this
Agreement and the terms and conditions incorporated in such recitals shall be
deemed integral parts of this Agreement, and all references in this Agreement
to this Agreement shall encompass such recitals and the terms and conditions
incorporated in such recitals.

     15.15  AMENDMENT.  This Agreement may be varied, amended or extended
only by the written agreement of the Parties through their duly authorized
officers or representatives, specifically referring to this Agreement.

     15.16  SEVERABILITY.  In the event that any provision of this
Agreement is held to be illegal, invalid or unenforceable in a final,
unappealable order or judgment (each such provision, an "invalid
provision"), then such provision shall be severed from this Agreement and
shall be inoperative, and the Parties promptly shall negotiate in good faith
a lawful, valid and enforceable provision that is as similar to the invalid
provision as may

                                                                  CONFIDENTIAL

be possible, while the remaining provisions of this Agreement shall remain
binding on the Parties hereto.

     15.17  HEADINGS.  The descriptive headings of the several articles
and sections of this Agreement are inserted for convenience only and do not
constitute a part of this Agreement.

     15.18  NO WAIVER OF RIGHTS.  No failure or delay on the part of
either Party in the exercise of any power or right hereunder shall operate as
a waiver thereof. No single or partial exercise of any right or power
hereunder shall operate as a waiver of such right or of any other right or
power. The waiver by either Party of a breach of any provision of this
Agreement shall not operate or be construed as a waiver of any other or
subsequent breach hereunder.

     15.19  REMEDIES CUMULATIVE; SPECIFIC PERFORMANCE.  All rights and
remedies granted to either Party under this Agreement are cumulative and in
addition to, and not in lieu of, any other rights or remedies otherwise
available to such Party at law or in equity. The Parties agree that any
breach by either Party of, or failure of either Party to perform, any
obligation under this Agreement shall constitute immediate and irreparable
damage to the other Party which cannot be fully and adequately compensated in
money damages and that, in the event of such breach or failure, the other
Party shall be entitled to injunctive relief and specific performance in
addition to any other remedies to which it may be entitled at law or in
equity.

     15.20  CONFIDENTIALITY OF AGREEMENT.  Each Party shall maintain the
confidentiality of this Agreement and all provisions of this Agreement and,
without the prior consent of the other Party, neither Party shall make any
press release or other public announcement of or otherwise disclose this
Agreement or any of its provisions to any Third Party (a) other than to its
Affiliates and to its own and its Affiliates' directors, officers, employees,
attorneys and accountants, and to the lead underwriter engaged by ADFORCE in
connection with any offering of securities of ADFORCE, whose duties
reasonably require familiarity with this Agreement, provided that such
Persons (including any such lead underwriter) are bound to maintain the
confidentiality of this Agreement, and (b) except for such disclosure as may
be required by applicable law or regulation, in which case the disclosing
Party shall provide the other Party with prompt advance notice of such
disclosure so that the other Party has the opportunity if it so desires to
seek a protective order or other appropriate remedy; provided that, in
connection with any offering of securities of ADFORCE, ADFORCE shall provide
in advance to NETSCAPE for review the form and content of any disclosure of
this Agreement or any of its provisions that may be required by applicable
law or regulation and, to the extent consistent with its disclosure
obligations under applicable law, include such modifications to such
disclosure as may be reasonably requested by NETSCAPE (except that ADFORCE
may file this Agreement as an exhibit to its registration statement if it
would constitute a "material agreement" under applicable law or regulation
and ADFORCE shall use its reasonable best efforts to obtain confidential
treatment of the portions of this Agreement that meet the SEC qualifications

for confidential treatment if so requested by NETSCAPE). The confidentiality
obligations of this Section 15.20 would apply, inter alia, to any disclosure
by ADFORCE of this Agreement or of any provisions of this Agreement to any
customer or potential customer of ADFORCE and any such disclosure would
constitute a breach of this Section 15.20. The Parties agree that any breach
of the provisions of this Section 15.20 by either Party, including, without
limitation, by any directors, officers or employees of such Party, would
constitute a breach by such Party of a material obligation hereunder for
which the other Party shall have the right, notwithstanding the provisions of
Section 14.2 above, to immediately terminate this Agreement without allowance
of any period to remedy such breach, such termination to be immediately
effective upon the receipt by the breaching Party of written notice of
termination from the nonbreaching Party.

     15.21  USAGE.  Wherever any provision of this Agreement uses the
term "including" (or "includes"), such term shall be deemed to mean
"including without limitation" and "including but not limited to" (or
"includes without limitation" and "includes but is not limited to")
regardless of whether the words "without limitation" or "but not limited to"
actually follow the term "including" (or "includes").

     IN WITNESS WHEREOF, the Parties hereto have caused this Agreement to
be executed by their duly authorized officers as of the date first above
written.

                                 EXHIBIT A

                             AD SERVING SERVICES

1. ADFORCE AD SERVING SERVICES.

     A. ADFORCE SERVICE DEFINITION.  The AdForce service ("AdForce Service")
is a proprietary Internet advertising administration system that will allow
NETSCAPE to manage advertising on its Internet properties. As part of the
AdForce Service, ADFORCE will provide NETSCAPE the ADFORCE "client"
("Client"), which NETSCAPE will use to (i) generate ad tags, (ii) schedule
advertising to run in the online environments in which NETSCAPE places those
ad tags, and (iii) generate reports on such advertising. In addition, ADFORCE
will maintain a centralized ADFORCE server complex from which ADFORCE will
electronically deliver advertising scheduled by NETSCAPE to the online
environments containing the ad tags placed by NETSCAPE. The delivery of
"Impressions," defined as the transmission of advertisements by ADFORCE to an
ADFORCE ad tag, will be verified by monthly third-party audits of the
AdForce Service, conducted by the Audit Bureau of Verification Services, Inc.
or another third party of comparable reputation chosen by ADFORCE. The
AdForce Service includes the targeting features and a suite of standard
reports available in the ADFORCE system listed below.

     B. THE ADFORCE SERVICE.  The AdForce Service includes the functionality
described in Section 1.A. above and as described below, with telephone client
services support from the hours of 6 a.m. to 6 p.m., Pacific Standard Time,
Monday-Friday, excluding major holidays. ADFORCE will also maintain 24 x 7
level technical service support via phone, cell phone or pager. In addition,
ADFORCE will provide up to four (4) days of account management support on
site at NETSCAPE each calendar month at no charge; unused days will not carry
over to subsequent calendar months. NETSCAPE may select the days and must
provide ADFORCE five (5) business days advance notice. Any additional days of
on-site training or support will be at a cost of $1,000 per day. The twelve
(12) days of monthly on-site account support to be provided by ADFORCE will
not include training for major ADFORCE releases, which will be provided to
NETSCAPE separately at no cost.

     C. CERTAIN NETSCAPE OBLIGATIONS.  NETSCAPE agrees to implement the ad
tags per the ADFORCE User Guide and Help documentation, and to use the
ADFORCE Client to schedule advertising it wishes ADFORCE to serve onto
NETSCAPE's Web sites. NETSCAPE confirms its commitment to use the AdForce
Service and Technology to serve not less than ninety percent (90%) of the ad
Impressions NETSCAPE controls on its NETSCAPE Netcenter online property, as
measured beginning April 15, 1999. However, if ADFORCE fails for any period
of time to meet its obligations under Sections 3.2, 4.3, 5.1, or 10.2 of the
Agreement or Section 7 of Exhibit A, then NETSCAPE may at its option reduce
its percentage commitment to a level NETSCAPE deems necessary until such time
as ADFORCE has come back into compliance. NETSCAPE agrees to provide ADFORCE
monthly volume forecasts of Impressions to be delivered using the AdForce
Service; these forecasts will be provided no later than three (3) days prior
to the beginning of each calendar month. NETSCAPE shall indemnify and hold
harmless ADFORCE from any liability and damages and costs (including
reasonable costs and attorney's fees) arising out of or relating to
advertising placed by NETSCAPE using the AdForce Service, including, without
limitation, content, libel, invasion of privacy, and rights of publicity.

2. OWNERSHIP OF CLIENT AND LIMITATIONS ON USE.  Subject to the terms and
conditions of this Agreement, NETSCAPE may use the Client on its premises
solely for purposes of using the AdForce Service. ADFORCE shall at all times
have sole and exclusive ownership of all right, title and interest in and to
such Client and the AdForce Service as a whole, any enhancements thereto
(except as provided in Section 2 above) and in any materials and data ADFORCE
provides to NETSCAPE. NETSCAPE may not copy, modify, alter, sell, distribute
or sublicense the Client, or reverse assemble, reverse compile or otherwise
attempt by any other method to create or derive the source programs of the
AdForce Service or the Client, nor authorize or contract with third parties
to do the same.

3. CONFIDENTIALITY. All passwords to ADFORCE, ADFORCE user guides, the
ADFORCE Client, and the ADFORCE "help" documentation, whether on-line or in
printed form, are confidential and proprietary to ADFORCE. All account
information input into the AdForce Service by NETSCAPE or ADFORCE for
campaigns running on NETSCAPE Web sites, such as advertiser contacts, costs
and billing information, and any NETSCAPE campaign-specific reports generated
by the AdForce Service are confidential to NETSCAPE.

4. ADFORCE SYSTEM DATA.  As set forth in Section 3 above, ADFORCE
acknowledges the confidentiality of the account information input into the
AdForce Service by NETSCAPE or ADFORCE for NETSCAPE campaigns and any
NETSCAPE campaign-specific reports generated by the AdForce Service. However,
during the course of delivering advertising to visitors to NETSCAPE's sites
or to any other site of any other ADFORCE customer, ADFORCE will collect and
maintain information necessary to target advertising on behalf of all its
customers, including NETSCAPE. This information includes, but is not limited
to the user's IP address, cookie, browser type and operating system, as well
as the time, date and ad tag of the request. ADFORCE will provide NETSCAPE
the ability to run any reports referenced on Exhibit A against such
information, ADFORCE and NETSCAPE both own all right, title and interest in
and to such information. Use of such information by either party shall at all
times comply with NETSCAPE's privacy policy, set forth at
http://home.netscape.com/legal_notices/privacy.html or at such other URL as
NETSCAPE may designate from time to time. ADFORCE shall have full freedom of
use of such information without need for accounting, however, such use shall
not expand beyond ADFORCE's actual use of such information as of the
Effective Date. Specifically, ADFORCE will provide to NETSCAPE on a weekly
basis the detailed HTTP server logs pertaining to user accesses on Netcenter.
The parties shall mutually agree to a procedure by which such logs will be
provided to NETSCAPE. Other logs may be requested with reasonable notice by
Netscape and such requests will not be unreasonably refused by ADFORCE.
Request for logs not generally provided by ADFORCE shall be subject to the
terms of Development Services as described in Article 5. All NETSCAPE requests
for system data will be on a prospective basis.

7.  PERFORMANCE METRICS

The Parties will measure real-world performance using a standard vendor such
as Keynote, Inverse Networks or another service mutually agreed upon.
NETSCAPE will be liable for the cost of the auditing services, not to exceed
$50,000. The ADFORCE system must provide:

A.  Average ad delivery availability: 99.98%, measured each calendar month,
    with no scheduled downtime. This metric also includes tracking functions
    such as impressions and click through counting. If the AdForce Service
    fails to meet this target level of performance, in addition to the
    response times referenced in Section 4.3, ADFORCE will provide NETSCAPE a
    "make good" on any ads which did not serve during any downtime in excess
    of the required availability metric (for example, if ad delivery is down
    0.03% of a given calendar month, then AdForce's make good shall apply
    only to the 0.01% excess over the required metric). Accordingly, AdForce
    will serve free of charge a number of ads equal to twice the number of ads
    not served during such excess downtime. Finally, failure by the AdForce
    Service to meet this performance metric for any four consecutive months
    shall, at NETSCAPE's option, constitute a breach of the Agreement.

B.  Administration system availability: 99.95%, less scheduled maintenance,
    measured each calendar quarter, with no scheduled downtime during Pacific
    Standard Time working hours (8 a.m.-6 p.m.). Maximum scheduled downtime in
    any given work week shall be 4 hours; measure also excludes monthly
    rebuilding of summary tables, provided they are executed only during
    weekend hours. Includes order entry/administration and reporting. Finally,
    failure by the AdForce Service to meet this performance metric for any four
    consecutive months shall, at NETSCAPE's option, constitute a breach of the
    Agreement.

C.  Single http-ad server delivery latency of no more than 2.5 seconds. This
    requirement will not apply at times when the Keynote Business 40 Benchmark
    Page latency is greater than three times its weekly average. Schedule for
    regular weekly measurements to be mutually agreed upon.

D.  Multiple ad delivery (maximum 9 ad requests) latency of no more than 10
    seconds. This requirement will not apply at times when the Keynote Business
    40 Benchmark Page latency is greater than three times its weekly average.
    Schedule for regular weekly measurements to be mutually agreed upon.

              February 1, 1999               $  776,159
              May 1, 1999                    $  778,133
              August 1, 1999                 $  866,529
              November 1, 1999               $  261,550

              TOTAL:                         $2,692,372
</TABLE>

* The figure for the quarter beginning November 1, is a prorated amount based
on the 22 days from November 1, 1999 until the end of the Initial Ad Serving
Services Term.

NETSCAPE will pre-pay an amount equal to $2.7 million, per Section 9.1.

Based on NETSCAPE's current impression forecast, this converts to an imputed
CPM rate as follows, and under no circumstances will NETSCAPE's CPM rate
exceed ADFORCE's own audited allocated CPM cost for the same period (defined
as ADFORCE's total cost of goods sold divided by ADFORCE's total
impressions), unless NETSCAPE chooses to increase ADFORCE's headcount
requirements:

              November 1, 1999               $0.08
</TABLE>

ADFORCE may use its audited allocation accounting methodology to bill
NETSCAPE; however, this amount may not exceed the computation of direct
obligations contained in Exhibit C, after updating Exhibit C for actual
impressions, headcount and other calculations. Specifically, those updates
will be made in an electronic version of Exhibit C, and the maximum
obligation for any given quarter will be the sum of those calculations, which
are described below.

1.  Actual impressions will be as measured and mutual agreed to by each party.

2.  Headcount:

-   Estimates will be adjusted per Section 9.1. It is currently estimated
    that there are 9 full-time-equivalents at ADFORCE working on the NETSCAPE
    account. It is agreed that 6 of these headcount, covering operations and
    account support, will not increase in number at any time. The three
    remaining headcount will work on providing quality assurance for campaign
    management, and this number could increase or decrease at NETSCAPE's
    option, depending on how NETSCAPE organizes this work in the future.

-   The formula for calculating headcount costs will be: [Number of headcount]
    multiplied by [$35,000] multiplied by [1.25 if before July 15, 1.40 if after
    July 15, 1999, or 1.0 if Section 6.2(a) controls]

                                      36
<PAGE>

                                                                  CONFIDENTIAL


3.  Facilities costs will be calculated according to the following formula:
    [Number of headcount in 1 above] multiplied by [$5,000] multiplied by
    [1.25 if before July 15, 1.40 if after July 15, 1999, or 1.0 if
    Section 6.2(a) controls]

4.  G&A will not change from Exhibit C, unless mutually agreed upon

5.  Bandwidth will not change from Exhibit C, unless mutually agreed upon

6.  Amortized capital, equipment and related costs will be based on Exhibit
    C. Specifically, the formula for any given quarter in which NETSCAPE is
    using the ADFORCE Ad Serving Service equals the sum of [the capital
    depreciation for capital expenses in that same quarter] and [the capital
    depreciation for capital expenses in any previous quarter in which NETSCAPE
    used the ADFORCE Ad Serving Service where the depreciation schedule has not
    expired].

    (a) The initial calculations for any three-month quarter are:

        (1)  Small System units purchased in quarter = [[Average NETSCAPE
             impressions served by ADFORCE per day] divided by [1,000,000]
             multiplied by [0.83] less [the sum of the total number of Small
             System units purchased in previous quarters]

        (2)  Small System units required in quarter = [Average NETSCAPE
             impressions served by ADFORCE per day] divided by [1,000,000]
             multiplied by [0.83]

        (3)  Cost of Small System purchased in quarter = [total small system
             units purchased in the quarter] multiplied by [$25,000]

        (4)  PC units purchased in quarter = [Small System units purchased in
             the quarter] divided by [1.0]

        (5)  Cost of PC's purchased in quarter = [PC units purchased in
             quarter] multiplied by [$5,000]

        (6)  Square footage required for Infrastructure build-out in quarter
             = [Small System units purchased in quarter] divided by [8] and
             then multiplied by [6]

        (7)  Cost of Infrastructure build-out in quarter = [square footage
             required for Infrastructure build-out in quarter] multiplied by
             [$350]

    (b) Summary calculations are:

        (1) Capital expenses in the quarter = the sum of [5.a.3], [5.a.5]
            and [5.a.7] above in the same quarter

        (2) Depreciation for the capital expenses incurred in the quarter =
            [5.b.1] divided by [8].

Not withstanding the foregoing, if less than a full quarter is completed the
maximum amount due will be prorated accordingly.

Not withstanding the foregoing, changes that may impact these actual
obligations include but are not limited to: NETSCAPE's assumption of
activities and operations that are provided by ADFORCE in the current
estimate, such as headcount, hardware, bandwidth, and facilities; and changes
to the impression forecast which impact these costs.

Specifically, unless the parties mutually agree otherwise, if NETSCAPE were
to assume any such activities and operations, NETSCAPE's obligation for the
subsequent periods would be reduced by a ratable amount in the
corresponding line item in Exhibit C, after adjusting for changes to Exhibit
C described above.

Unless the parties mutually agree otherwise, milestones regarding the timing
and adjustment of payments will be made per Section 9.1 of the Agreement.

                             EXHIBIT D

             MUTUAL CONFIDENTIAL DISCLOSURE AGREEMENT

This Mutual Confidential Disclosure Agreement ("Agreement") is entered into
between NETSCAPE Communications Corporation ("NETSCAPE") and IMGIS, INC, dba
ADFORCE ("Company"), and is effective as of the date of execution by NETSCAPE
("Effective Date"). Each party (the "Receiving Party") understands that the
other party (the "Disclosing Party") may disclose certain Confidential
Information (as defined in Section 1 below) under this Agreement. NETSCAPE
and Company agree as follows:

1.  DEFINITION. "Confidential Information" shall mean (i) all information   
    disclosed in tangible form by the Disclosing Party and marked
    "confidential" or "proprietary", and (ii) all information disclosed
    orally or otherwise in intangible form by the Disclosing Party and
    designated as confidential or proprietary at the time of disclosure.
    Confidential Information may include, without limitation, computer
    programs, code, algorithms, names and expertise of employees and
    consultants, know-how, formulas, processes, ideas, inventions (whether
    patentable or not), schematics and other technical, business, financial
    and product development plans, forecasts, strategies and information.

2.  PURPOSE. The Receiving Party shall use the Confidential Information only
    for the following purposes:

    a)  To evaluate whether to enter into a contemplated business transaction;
    and

    b) if NETSCAPE and Company enter into such contemplated business
    transaction, to fulfill each party's commitments under the agreement for
    such business transaction.

3.  CONFIDENTIALITY OBLIGATION. The Receiving Party agrees to protect the
    Confidential Information by using the same degree of care, but not less
    than a reasonable degree of care, to prevent the unauthorized use,
    dissemination or publication of the Confidential Information as the
    Receiving Party uses to protect its own confidential or proprietary
    information of a like nature. The Receiving Party shall limit the use of
    and access to the Disclosing Party's Confidential Information to the
    Receiving Party's employees or independent contractors who need to know
    such Confidential Information for the purposes set forth in Section 2
    above and who have entered into binding obligations of confidentiality
    substantially similar to the obligations set forth herein.

4.  TERM. The Receiving Party's obligations to protect Confidential
    Information hereunder shall expire 3 years from the date of each such
    disclosure of Confidential Information, except when such Confidential
    Information disclosed by the Disclosing Party is source code, in which
    case the Receiving Party's obligations to protect such Confidential
    Information shall be perpetual.

5.  EXCLUSION. Confidential Information as defined in Section 1 above shall
    not include Confidential Information that: (i) is or becomes a matter of
    public knowledge through no fault of the Receiving Party; or (ii) was in
    the Receiving Party's possession or known by it prior to receipt from the
    Disclosing Party; or (iii) was rightfully disclosed to the Receiving
    Party by another person without restriction; or (iv) is independently
    developed by the Receiving Party without access to Disclosing Party's
    Confidential Information. The Receiving Party may disclose Confidential
    Information pursuant to any statutory or regulatory authority or court

                                                                  CONFIDENTIAL

    order, provided the Disclosing Party is given prompt written notice of
    such requirement and the scope of such disclosure is limited to the
    extent possible.

6.  INDEPENDENT DEVELOPMENT. The terms of confidentiality under this Agreement
    shall not be construed to limit either party's right to independently
    develop or acquire products without use of the other party's Confidential
    Information. Further, Confidential Information as defined in Section 1
    above shall not include the Residuals resulting from access to such
    Confidential Information. The term "Residuals" means information in
    intangible form which may be retained in the unaided memories of
    Receiving Party's employees or independent contractors who have had
    access to the information. An employee's or contractor's memory will be
    considered to be unaided if the employee has not intentionally memorized
    the Confidential Information for the purpose of retaining and
    subsequently using or disclosing it. Neither party shall have any
    obligation to limit or restrict the assignment of such persons or to pay
    royalties for any work resulting from the use of Residuals. However, the
    foregoing shall not be deemed to grant to either party a license under
    the other party's copyrights or patents.

7.  RETURN OF CONFIDENTIAL INFORMATION. Upon written request by the Disclosing
    Party at any time, the Receiving Party shall: (i) turn over to the
    Disclosing Party all Confidential Information of the Disclosing Party,
    all documents or media containing the Confidential Information, and any
    and all copies or extracts thereof, or (ii) destroy the Confidential
    Information, and any and all copies or extracts thereof, and provide the
    Disclosing Party with written certification of such destruction signed
    by an authorized representative of the Receiving Party.

8.  EQUITABLE RELIEF. The Receiving Party acknowledges and agrees that due to
    the unique nature of the Disclosing Party's Confidential Information,
    there may be no adequate remedy at law for any breach of its obligations.
    The Receiving Party further acknowledges that any such breach may allow
    the Receiving Party or third parties to unfairly compete with the
    Disclosing Party resulting in irreparable harm to the Disclosing Party
    and, therefore, that upon any such breach or any threat thereof, the
    Disclosing Party shall be entitled to seek appropriate equitable relief
    in addition to whatever remedies it may have at law. The Receiving Party
    will notify the Disclosing Party in writing immediately upon the
    occurrence of any such unauthorized release or other breach.

9.  INTELLECTUAL PROPERTY RIGHTS. Neither party acquires any intellectual
    property rights or any other rights under this Agreement or through any
    disclosure hereunder, except the limited right to use the Confidential
    Information in accordance with this Agreement.

10. WARRANTY. THE CONFIDENTIAL INFORMATION IS DISCLOSED UNDER THIS AGREEMENT
    IS DELIVERED "AS IS," AND ALL REPRESENTATIONS OR WARRANTIES, WHETHER
    EXPRESS OR IMPLIED, INCLUDING WARRANTIES OR CONDITIONS FOR FITNESS FOR A
    PARTICULAR PURPOSE, MERCHANTABILITY, TITLE AND NONINFRINGEMENT, ARE
    HEREBY DISCLAIMED.

11. NETSCAPE SUBSIDIARIES. NETSCAPE's wholly owned subsidiaries, by signing
    this Agreement on behalf of NETSCAPE and returning a fully executed
    original or copy to the NETSCAPE Legal Department, shall be entitled to
    disclose NETSCAPE's Confidential Information and receive Company's
    Confidential Information on a need to know basis only on behalf of
    NETSCAPE under this Agreement, provided such subsidiaries comply with the
    terms and conditions of this Agreement and further provided such
    disclosures or receipt of

    party unless made in writing and signed by a duly authorized
