         -------------------------------
under all NetIQ intellectual property and proprietary rights, a non-exclusive,
perpetual, worldwide, irrevocable, license to compile, make, use, sell, offer to
sell, reproduce, create derivative works, sublicense and distribute the Licensed
Software and the Licensed Materials, and derivative works thereof.   Microsoft
and NetIQ acknowledge certain limitations and restrictions on the license grants
hereunder as set forth in Sections 2(b) and 5(e).

     b.  Limitations on Microsoft's License.  The foregoing license grant is
         -------------- -------------------
limited with respect to Microsoft's ability to use the Licensed Software or
Licensed Materials to develop and ship NT Agents in the following manner.  For
any release of MOM, Microsoft shall have no right to use the Licensed Software
and Licensed Materials to develop and ship a NT Agent other than the Microsoft
NT Agent, provided that NetIQ continues to provide a NT Agent for then-current
and all prior versions of MOM, consistent with Microsoft's then-current policy
for supporting prior versions of MOM (or as mutually-agreed at the Vice
President level) (i) with at least the functionality of the OM version 3.3 NT
Agent, (ii) with at least the level of support provided for the NT Agent on the
Effective Date, and (iii) that is priced comparably with NetIQ's offerings of
Agents of similar functionality for other platforms (collectively, providing
"Market Satisfaction").  If NetIQ does not provide Market Satisfaction with
respect to the NT Agent for that release, Microsoft may notify NetIQ and NetIQ
shall have ninety (90) days to reestablish Market Satisfaction for that NT
Agent.  If NetIQ fails to reestablish Market Satisfaction, then the license
limitation set forth in this Section 2(b) shall terminate as to that release of
MOM.  NetIQ shall use commercially reasonable efforts to ship a NT Agent for any
commercial release of MOM within 60 days of general availability.

     c.  Microsoft's Grant to NetIQ.  Microsoft hereby grants to NetIQ, under
         --------------------------
all Microsoft intellectual property and proprietary rights, a non-exclusive,
perpetual, worldwide, irrevocable license to compile, make, use, sell, offer to
sell, reproduce, create derivative works of and distribute all bug fixes to the
Licensed Software, and derivative works of such bug fixes, for the sole purpose
of creating MOM Extending Technologies.  During the Collaboration Period,
Microsoft further hereby grants to NetIQ, under all Microsoft intellectual
property and proprietary rights, a non-exclusive, worldwide license to review
any reasonably necessary or useful portions of the MOM source code which
portions may not include all Microsoft source code that is a derivative of
Licensed Software solely in its read-only form and as a reference for the
purpose of developing and supporting the MOM Extending Technologies. Upon
completion of the Collaboration Period and at NetIQ's request, Microsoft shall
negotiate in good faith with NetIQ to provide NetIQ with a read-only source code
license under Microsoft's then-standard source code licensing practices.

     d.  Ownership.  For avoidance of doubt, NetIQ shall retain all right, title
         ---------
and interest, including all intellectual property and proprietary rights, in and
to the Licensed Software and Licensed Materials, and any MOM Extending
Technologies, subject to any license grants to Microsoft hereunder, and NetIQ
shall have the right to obtain, register or otherwise perfect any of its
intellectual property rights therein.

3.   Acquisition of the Right to Use the Licensed Software to Develop and Ship
     -------------------------------------------------------------------------
an NT Agent. If Microsoft wishes to acquire the right to use the Licensed
-----------
Software and Licensed Materials to ship any NT Agent, other than the Microsoft
NT Agent (and provided that NetIQ has continued to provide Market Satisfaction
as set forth in Section 2(b)), Microsoft shall notify NetIQ and such notice
shall specify the purposes for which Microsoft desires to acquire such rights.
Microsoft and NetIQ agree to negotiate in good faith to determine if such
purposes may be fulfilled through some mutually agreed upon means. If Microsoft
and NetIQ cannot reach an agreement that satisfies Microsoft's stated purpose,
then, if twelve months have elapsed since the Street Date, Microsoft shall
acquire rights to develop and ship any NT Agent upon Microsoft's payment to
NetIQ of the following sums at the following time periods: (i) one hundred and
fifty million dollars ($150,000,000) between 12 months to 24 months of the
Street Date; (ii) one hundred million dollars ($100,000,000) between 24 months
and 36 months of the Street Date; and (iii) seventy-five million dollars
($75,000,000) after 36 months of the Street Date.

4.   Development Collaboration.
     -------------------------

     a.  NetIQ shall deliver to Microsoft the Licensed Software and an initial
version of the Licensed Materials within two (2) weeks of the Effective Date.
Upon receipt of such Licensed Software and Licensed Materials, Microsoft shall
evaluate such Licensed Software and Licensed Materials.  Microsoft shall
communicate to NetIQ its acceptance or rejection of the Licensed Software and
Licensed Materials within thirty (30) days of the Effective Date.  Microsoft's
acceptance shall not be deemed a waiver by Microsoft of NetIQ's obligation to
deliver the Licensed Software and Licensed Materials hereunder.  NetIQ shall
deliver the final version of the Licensed Materials within four (4) weeks of the
Effective Date.  Upon commercial release of OM version 3.3 by NetIQ, Microsoft,
upon reasonable notice, shall have the right to audit the source code tree for
OM version 3.3 during normal business hours.  Such audit shall be at Microsoft's
expense.  NetIQ agrees to provide all reasonably necessary assistance to
Microsoft to facilitate such audit.   NetIQ agrees that there will be no
material functional regression of the commercially released OM version 3.3, as
compared with OM version 3.3 existing as of the Effective Date.

     b.  During the Collaboration Period, except as limited herein and by
Section 5(a), NetIQ shall provide the Development Team, which, at Microsoft's
election, shall be comprised of a minimum of up to **** Team Members at the
Microsoft Facility and which shall consist of at least **** engineers at all
times. Ten days after the Release To Manufacturing of OM version 3.3, NetIQ
shall use commercially reasonable efforts to provide, upon thirty (30) days
prior notice from Microsoft, a maximum, at any one time, of up to **** Team
Members. During the first six months of the Collaboration Period, at least one
(1) Team Member at the Microsoft Facility shall be a build/development engineer

     c.  At Microsoft's election, NetIQ and Microsoft will collaborate on the
definition of a licensing mechanism that provides a coherent licensing strategy
to customers of MOM and MOM Extending Technology.

     d.  Team Members shall be highly familiar with and highly experienced with
the Microsoft Windows platform and the development of OM.   NetIQ shall use
commercially reasonable efforts to ensure that (i) each Team Member meets
Microsoft's reasonable hiring standards, as communicated to NetIQ, and (ii) all
NetIQ personnel comply with Microsoft's published standard policies and
procedures with respect to on-site personnel at the Microsoft Facility.  Such
standard policies and procedures shall not alter the intellectual property
rights between the Parties set forth in this Agreement.

     e.  At NetIQ's expense, NetIQ may also maintain up to **** NetIQ Employees
as technical contacts at the Microsoft Facility during the Collaboration Period,
to aid in NetIQ's development of MOM Extending Technologies. Such **** Employees
shall not be considered as a part of the Development Team resources that NetIQ
is obligated to provide pursuant to Section 4(b). At Microsoft's expense,
Microsoft may also maintain up to **** Microsoft employees as technical contacts
at a NetIQ Facility during the Collaboration Period, to assist with Microsoft's
development obligations.

     f.  Unless mutually agreed upon differently by the Parties (at the Vice-
President level for each Party), NetIQ shall use commercially reasonable efforts
to deliver working, demonstrable betas of Agents for any three of the following
four platforms: (i) AIX, (ii) HP-UX, (iii) Solaris and (iv) Novell server
software.  NetIQ will also use commercially reasonable efforts to deliver
working, demonstrable betas of modules for any two of the following three
applications: (i) Lotus Domino, (ii) Oracle 8i Enterprise Edition, and (iii) SAP
R/3.  NetIQ shall use commercially reasonable efforts to complete all such beta
Agents or modules in time for the first official announcement of the Release To
Manufacturing version (the "Launch") of MOM.  With respect to the remaining beta
Agents and modules for the fourth platform and third application not anticipated
to be completed by the Launch, NetIQ shall use commercially reasonable efforts
to complete such Agents and modules within four months of the Launch.  NetIQ
shall use commercially reasonable efforts to complete final versions of all such
Agents and modules no later than six months after Launch.

     g.  NetIQ may, from time to time, engage Microsoft in discussions regarding
providing additional items as part of the Licensed Software and/or Licensed
Materials. Should NetIQ provide such additional items to Microsoft, the parties
shall engage in good faith negotiations regarding when Microsoft may incorporate
such items in a future release of MOM. The ultimate decision whether to include
such technologies shall reside with Microsoft.

     h.  Upon NetIQ's request, Microsoft shall use commercially reasonable
efforts to provide information to NetIQ on publicly documented application
programming interfaces and database schema ("APIs") for MOM.  NetIQ shall only
write to APIs.  Should NetIQ require a particular new API, NetIQ shall notify
Microsoft in writing, and Microsoft shall in good faith discuss the requirements
of such API with NetIQ.  Notwithstanding any provision to the contrary,
Microsoft retains sole discretion to document, expose, or otherwise make
available to any Party, including NetIQ, any APIs.

**** [C]onfidential treatment has been requested for the redacted portions. The
confidential redacted portions have been filed separately with the Securities

     i.  For avoidance of doubt, NetIQ may build MOM Agent Subsystems for Win9x,
NT Embedded (based on Windows NT 4.0), WinCE, Windows ME, and future Microsoft
operating systems, whether on PCs or non-PC devices.

5.   Covenants/Restrictions/Feedback/Residuals
     -----------------------------------------

     a.  Microsoft agrees that neither the Windows Operations Management team
nor the Windows Management Instrumentation team will solicit directly, or
knowingly solicit indirectly, the employment or retention as a contractor of any
current or former Team Member during the time that such Team Member is providing
services in connection with the Collaboration and for six months thereafter.  If
any current or former Team Member does become a Microsoft employee (or
contractor), NetIQ's obligations to provide a maximum number of **** Team
Members at any one time during the Collaboration Period shall be accordingly
reduced.  In addition, the Parties shall discuss the issue at the Vice President
level, and Microsoft shall consider in good faith the possibility of reducing
the minimum number of Team Members that NetIQ is then obligated to provide.

     b.  Any NetIQ Employee who views MOM source code may not work on NetIQ
products that run on non-Microsoft platforms (excepting MOM Extending
Technologies) for a period of six months after they last view such MOM source
code.  Such NetIQ Employees may document interfaces in the source code, and
other NetIQ Employees who view such documentation will not be subject to the
limitation set forth herein.  However, NetIQ Employees viewing OM source code
separate from the MOM source code shall not be subject to the restrictions set
forth herein.

     c.  Except as provided elsewhere in this Agreement or any other written
agreement between the Parties, NetIQ hereby grants to Microsoft an unrestricted
license to make, use, sell, offer to sell, create derivative works, and
reproduce all information, feedback, suggestions and advice, in whatever form,
provided to Microsoft by any Team Member or any other NetIQ personnel during the
Collaboration Period.

     d.  Microsoft hereby grants to NetIQ the right to retain and use Residuals
from all information received or reviewed by NetIQ Employees. None of these
NetIQ Employees shall knowingly and intentionally use such Residuals to create
or contribute to products that run on non-Microsoft platforms (excepting for MOM
Extending Technologies).  The term "Residuals" means information in intangible
form, which is retained in memory by persons who have had access to the
Confidential Information, including ideas, concepts, know-how or techniques
contained therein.

     e.  The Parties shall refrain from disclosing any Confidential Information
of a Disclosing Party to third parties for five (5) years following the date
that a Disclosing Party first discloses such Confidential Information to a
Receiving Party.  The Parties agree to take reasonable security precautions, at
least as great as the precautions it takes to protect its own confidential
information, but no less than reasonable care, to keep confidential the
Confidential Information of a Disclosing Party.  The Licensed Software (to the
extent it comprises source code) and certain portions of the Licensed Materials
that are marked or otherwise known to be confidential shall be Confidential
Information of NetIQ.  The MOM source code shall be Confidential Information of
Microsoft.  Notwithstanding any provision to the contrary, Microsoft may license
any Microsoft technology incorporating the Licensed Software and Licensed
Materials (and any derivatives thereof) to third parties pursuant to Microsoft's
source code licensing practices.  For a period of three years from the Effective
Date, however, Microsoft agrees not to intentionally and knowingly license or
otherwise disclose the Licensed Software and Licensed Materials (and any
derivatives thereof, including MOM) to any systems management vendor or other
third party for the purpose of allowing such systems management vendor or third
party to create a product that competes with NetIQ's system management products.
Microsoft may publish small sections (typically less than

100 lines) of source code for the purposes of SDK samples. Where these sections
of code contain fragments of Licensed Software, Microsoft must obtain approval
of a NetIQ Vice President before publishing such SDK samples.

6.  Nonassertion of Patent Claims
    -----------------------------

In addition to the license grants set forth in Section 2, each Party hereby
agrees not to assert against the other Party (or such other Party's customers)
any claims of any patents owned or licensable by the Party with an effective
filing date before one year after the end of the Collaboration Period, or one
year after the termination or cancellation of this Agreement, which claims cover
any modifications, updates, or extensions to the Licensed Software, Licensed
Materials, or MOM Extending Technologies on Microsoft platforms. Microsoft's
agreement not to assert patents does not apply to NetIQ's creation of
technologies running on non-Microsoft platforms, except for MOM Extending
Technologies.

7.   Warranties/Indemnities/Patent Enforcement

hereby warrants that the Licensed Software and Licensed Materials do not
infringe any copyright, trade secret, or other proprietary right of any third
party.  NetIQ warrants that, to the best of its knowledge on the Effective Date,
the Licensed Software and the Licensed Materials do not infringe any patents
held by any third party.

     b.  NetIQ's delivery of the Licensed Software and Licensed Materials to
Microsoft, and/or the performance of any other NetIQ obligation hereunder shall
not violate any agreement or obligation between NetIQ and any third party.
Microsoft's performance of any of Microsoft's obligations hereunder shall not
violate any agreement or obligation between Microsoft and any third party.

     c.  The Licensed Software shall not contain any Open Source.  "Open Source"
means any software code that contains, or is derived in any manner (in whole or
in part) from, any software that is distributed under any of the following
licenses or distribution models, or licenses or distribution models similar to
any of the following: (a) GNU's General Public License (GPL) or Lesser/Library
GPL (LGPL), (b) The Artistic License (e.g., PERL), (c) the Mozilla Public
License, (d) the Netscape Public License, (e) the Berkeley software design (BSD)
license including Free BSD or BSD-style license, (f) the Sun Community Source
License (SCSL), (g) an Open Source Foundation License (e.g., CDE and Motif UNIX
user interfaces), and (h) the Apache Server license.

     d.  In the event of a breach by NetIQ of any of the warranties set forth
above, NetIQ warrants that it shall use best efforts to ensure that Microsoft
has all rights to the Licensed Software and Licensed Materials that Microsoft
would otherwise have if NetIQ were not in breach of such warranties.  In no
event shall NetIQ be required to expend more than the remaining amount of its
total liability cap of One Hundred Million Dollars (as set forth in Section
12(d)) to satisfy its best efforts obligations hereunder.

     e.  NetIQ shall, at its expense, defend any claim or action brought against
Microsoft, and Microsoft's subsidiaries, affiliates, directors, officers,
employees, agents, or independent contractors, to the extent that such claim or
action is based on a claim or action caused by NetIQ's breach of any of NetIQ's
warranties as set forth herein ("Claims").  Microsoft will give NetIQ reasonable
notice upon learning of any Claim and will reasonably assist NetIQ in the
defense and settlement of such Claim.  NetIQ will indemnify Microsoft for any
reasonable costs, expenses, and other fees reasonably incurred by

                                       7
<PAGE>

Microsoft in connection with such Claim. NetIQ shall defend the Claim with
counsel reasonably acceptable to Microsoft and NetIQ shall only settle such
Claim with Microsoft's reasonable consent.

     f.  NetIQ agrees it will Enforce (as defined herein), at the request of and
expense of Microsoft, any rights it has in the NetIQ patents licensed to
Microsoft ("NetIQ Licensed Patents") against a third party who is infringing the
NetIQ Licensed Patents.  "Enforce" means giving notice of a patent infringement
claim to the third party and the filing and service of a patent infringement
complaint in a court of competent jurisdiction within a time period agreeable to
the Parties, together with the diligent and competent prosecution of any
litigation so initiated.

8.   Collaboration Restrictions
     --------------------------

     a.  If, at any time after the date that is twelve months after the Street
Date, NetIQ announces, promotes or releases a NetIQ product that runs on a
Microsoft platform on which MOM is available, and such NetIQ technology and
marketing efforts could have the effect of or are designed to have the effect of
supplanting or eliminating the need for the MOM Core, then effective as of such
announcement, promotion or release date, all of Microsoft's marketing
obligations under Section 10 herein shall terminate.  In addition, Microsoft
shall be relieved of any further obligation to pay the Marketing Collaboration
Support Fee (as defined below) and the unpaid portion of the Licensing Fee
payable hereunder shall be reduced by the lesser of (a) Fifty Million Dollars
(US $50,000,000), or (b) the amount not yet due and payable.

     b.  NetIQ actions in (i) announcing, promoting, or releasing OM and AM
prior to the date that is twelve months after the Street Date (the "NetIQ
Released Products"), (ii) releasing bug fixes or QFEs for such NetIQ Released
Products at any time, and (iii) such other actions as mutually agreed upon by
the Parties (at the Vice President level), shall not be considered actions that
supplant the MOM Core.  For the avoidance of doubt, NetIQ's sales of licenses to
NetIQ Released Products after the period which is twelve months after the Street
Date shall not be considered actions that supplant the MOM Core.

     c.  If NetIQ licenses or sells the OM Base Modules source code to any third
party, then Microsoft shall be relieved of all marketing obligations under
Section 10, and all obligations to pay any unpaid portion of the Licensing Fee
and Marketing Collaboration Support Fee not accrued on the date of such license.
The foregoing shall not apply to NetIQ's distribution of its own commercial
products that utilize or incorporate the OM Base Modules.

9.   Fees
     ----

     a.  Microsoft shall pay to NetIQ a fee in the amount of One Hundred
Seventy-Five Million Dollars (US$175,000,000) (the "Licensing Fee").  This
Licensing Fee shall be paid according to the payment schedule set forth in
Exhibit C.
---------

     b.  Microsoft shall provide Ten Million Dollars (US$10,000,000) for each
year of the Collaboration Period from the Effective Date for marketing and
collaboration support of MOM and MOM Extending Technologies (the "Marketing
Collaboration Support Fee").  Of such amounts, Microsoft shall pay to NetIQ One
Million Two Hundred and Fifty Thousand Dollars (US$1,250,000) each calendar
quarter, during the first week of the second month of each quarter, commencing
November 2000.  NetIQ shall spend this amount in its reasonable discretion for
activities relevant to the Collaboration and NetIQ shall provide a report to
Microsoft describing such activities and the corresponding expenditures on a
quarterly basis within 30 days after the end of the quarter.  The balance of
Five Million Dollars annually will be spent by Microsoft upon mutual agreement
of the Parties and Microsoft shall provide to NetIQ a report describing such
mutually-agreed upon activities and the expenditures thereon on a quarterly
basis

                                       8

meetings at the Microsoft Facility, as an audio or video teleconference, or as
otherwise mutually agreed, between their respective marketing management and
development management personnel for the purpose of discussing, maintaining
and/or improving the Collaboration and the relationship between the two
companies via the exchange of mutually beneficial information.   Annual
                                                                 ------
Meetings. Microsoft and NetIQ shall also conduct an annual meeting at the
--------
Microsoft Facility, as an audio or video teleconference, or as otherwise
mutually agreed, between designated representatives of NetIQ and the Microsoft
Vice Presidents in charge of development and marketing of MOM for the purpose of
discussing, maintaining and/or improving the Collaboration and the relationship
between the two companies via the exchange of mutually beneficial information.

     b.  Ongoing Training.  NetIQ and Microsoft shall identify opportunities to
         ----------------
provide training and knowledge transfer on a "train-the trainer" basis on their
respective products to their direct and indirect sales channels.  To this end,
each Party commits to provide twelve (12) training days per year to be provided
to the other Party's personnel at no cost; provided, that such training is
conducted at the relevant training Party's Facilities and travel expenses and
costs of the trained personnel shall be borne by the Party receiving such
training unless otherwise specifically agreed.  In addition to these training
obligations, Microsoft shall field four (4) management champions to sell and
promote MOM and to promote the adoption of NetIQ's value-add solutions and
services for MOM, and the promotion of the alliance relationship with NetIQ
within the Microsoft sales organizations.

     c.  Upgrade Program.  The Parties shall collaborate to offer an Upgrade
         ---------------
Program that shall comprise a special discounted upgrade license, training, and
sales/migration support (such as Microsoft Consulting Services). As part of the
Upgrade Program, Microsoft will offer a standard Microsoft discounted Version
Upgrade Product license ("VUP") to enable existing NetIQ OM or AM customers (the
"Existing NetIQ Customers") to ease the upgrade to MOM.  This VUP will be
available for a period of two (2) years after the Street Date.   Alternatively,
if an Existing NetIQ Customer who has purchased up to one year of maintenance
from NetIQ, on terms and conditions substantially similar to standard NetIQ
maintenance contracts on the Effective Date, elects to use MOM as an alternative
to some or all of its NetIQ products ("Replaced Products"), such Existing NetIQ
Customer shall receive an upgrade to MOM and Microsoft maintenance for MOM for
the remainder of such Existing NetIQ Customer's maintenance contract with NetIQ
at no cost to the Existing NetIQ Customer, provided that such Existing NetIQ
Customer enters into a maintenance contract with Microsoft for the remainder of
the period otherwise covered by its existing NetIQ maintenance contract.
Thereupon, NetIQ shall transfer to Microsoft the prorated, unused portion of the
maintenance fees attributable to the Replaced Products paid by such Existing
NetIQ Customers to NetIQ.

     d.  Distribution Rights.  Microsoft and NetIQ will enter into a standard
         -------------------
Microsoft ISV Royalty License and Distribution Agreement for three (3) years
from the Street Date, pursuant to which NetIQ will be granted rights to include
MOM, SQL and other mutually agreeable Microsoft products consistent with the
terms of such agreement(s) with NetIQ's products and license such products
through NetIQ's direct and indirect sales channels.  The Parties will work in
good faith on a program pursuant to

                                       9
<PAGE>

which NetIQ will report to Microsoft sales of products that include MOM such
that Microsoft may credit the Microsoft sales force that otherwise would have
sold MOM with the sales accrued through such programs. Microsoft shall assist
NetIQ in identifying and entering into the most-favorable distribution and
support programs that meet NetIQ's requirements and for which NetIQ qualifies.
When including MOM in a value-add product, NetIQ may alter the visual appearance
of MOM by substituting the product name, icons, and other graphical elements
with similar elements provided by NetIQ, provided that NetIQ include a prominent
Microsoft-related tag-line approved by Microsoft (e.g., "Powered by MOM"), and
NetIQ shall credit Microsoft appropriately in the license. Consistent with
Microsoft's engineering obligations under this Agreement, Microsoft will support
the ability of NetIQ to make such alterations. NetIQ will ensure that products
distributed under the ISV Royalty License and Distribution Agreement do not
disable any functionality or impair upgradeability of MOM or other products as
distributed by Microsoft. Any covenants in this Section 10(d) may be included
with the Microsoft ISV Royalty License and Distribution Agreement.

     e.  Joint Promotion of NetIQ Products and MOM.  Microsoft and NetIQ will
         -----------------------------------------
engage in activities that promote the sale and distribution of NetIQ's products
and MOM through their direct and indirect sales channels, including Microsoft's
affiliated partners.  Such activities shall include targeted joint field sales
calls, jointly sponsored seminars and webcasts as described in Section 10(j)
below, and selective targeted channel activity focused on establishing NetIQ
channel relationships with key Microsoft alliance partners focused in the MOM
market space. In addition, the Parties will jointly target in good faith, over
the Collaboration Period, 450 accounts as follows:  100 discrete accounts in the
first year after the Street Date, 150 discrete accounts in the second year after
the Street Date, and 200 discrete accounts in the third year after the Street
Date.

     f.  Public Announcement.  Microsoft and NetIQ will jointly issue a public
         -------------------
announcement of the alliance between Microsoft and NetIQ at a Microsoft event,
with NetIQ positioned as described in Section 10(k) below.  In addition, NetIQ
will be positioned as described in Section 10(k) during the Launch of MOM,
providing opportunities to showcase NetIQ's value-added solutions for MOM.

     g.  Quarterly Announcements.  NetIQ and Microsoft intend to collaborate to
         -----------------------
generate events, press related-activities or case studies each quarter designed
to promote the MOM solution and NetIQ's value-add offerings.

     h.  Notices.  All MOM products that incorporate the Licensed Software shall
         -------
have the appropriate NetIQ copyright notices, including a URL to a Microsoft web
site that will redirect to the NetIQ web site.

     i.  Tags.  Microsoft will provide a mutually agreeable special NetIQ-
         ----
exclusive tag line for the relationship.  This tag line can be used by the
Parties during marketing activities and such tag line will be introduced at the
Launch.

     j.  Joint Marketing to Customers/EBC.  The Parties shall mutually agree
         --------------------------------
upon and conduct joint-marketing campaigns promoting the products and technology
of NetIQ and Microsoft to each other's installed base of users and new
prospective customers, including a minimum of 10 seminars and 2 webcasts per
calendar year, which shall be paid from the Marketing Collaboration Support Fee.
These campaigns may include other partners of the Parties as mutually agreed.
Microsoft shall include MOM Extending Technologies whose primary purpose is to
extend MOM on Windows in the Executive Briefing Centers Showcase, Competency
Centers, Solutions Centers, and other similar facilities, where appropriate.

                                       10

     k.  Premier ISV.  For a two year period commencing on the Effective Date
         -----------
and in connection with the marketing activities set forth in this Agreement and
other appropriate corporate-driven activities, Microsoft shall designate NetIQ
as Microsoft's publicly acknowledged Premier ISV, or similar designation,
provided only to NetIQ, which shall be the highest level of designation that
Microsoft provides for any ISV that provides the equivalent of MOM Extending
Technologies, and shall make use of the tag line in Section 10(i) above.  The
Parties currently anticipate that the following shall be MOM Extending
Technologies by the Launch of MOM and thus NetIQ shall be the Premier ISV for
each of the following:  Security Management, Windows NT4 Operations Management,
Operations Management of non-Microsoft platforms and applications from MOM,
Network Performance Management, Extended Reporting and others as mutually
agreed.  The aggregate endorsement of NetIQ around MOM Extending Technologies
shall be greater than for any other ISV for the equivalent of MOM Extending
Technologies.  Microsoft shall also provide NetIQ with a marketing endorsement
of NetIQ as a marketing partner of administration products for NT and Windows
2000 and any other mutually agreeable areas, which do not compete with the
proposed Microsoft Operations Manager for Windows 2000 software product or other
Microsoft management solutions.  If NetIQ provides Microsoft with information
that Microsoft is not adhering to the designation obligations set forth above,
Microsoft shall confirm such information and, if appropriate as reasonably
determined by Microsoft, shall take corrective action.  Provided that the public
relationship is successful, the Parties may agree to extend this to the end of
the Collaboration Period.  For each particular product, NetIQ shall ensure that
such product is "best of breed," and if such product is clearly not "best of
breed" as reasonably determined by Microsoft, Microsoft may suspend NetIQ's
status as Microsoft's Premier ISV as to such product.  NetIQ may improve such
product and reapply for Premier ISV status with respect to such product.

     l.  Links.  Microsoft will provide links from its Microsoft.com website in
         -----
one or more appropriate locations providing information on MOM to NetIQ areas
promoting technologies extending MOM.   NetIQ would provide links to Microsoft's
management sites from appropriate links in NetIQ's websites for management
services and software.

     m.  General Marketing Collateral.  Microsoft and NetIQ will provide the
         ----------------------------
following general marketing collateral and initiatives using funds from the
Marketing Collaboration Support Fee, which marketing collateral and initiatives
shall include, as appropriate with mutually agreed upon content:  (a) public
relations support, including supporting quotes in NetIQ press releases related
to MOM Extending Technologies; (b) joint events, including conferences,
seminars, tradeshows, webcasts; (c) presentations at appropriate Microsoft
internal events, including MTB, Fusion, SE Airlifts, sponsor/promote regional
events; and (d) joint advertising, collateral, case studies, white papers,
brochures and videos.

     n.  Adaptation of Discovery Mechanism.  The Parties will mutually agree to
         ---------------------------------
an adaptation of the current NetIQ discovery mechanism within MOM toward the
goal of directing customers to a Microsoft website that contains nonexclusive
links to the NetIQ website promoting or selling MOM Extending Technologies.

     o.  Global Technology Partner.  Microsoft will place NetIQ in the category
         -------------------------
of Global Technology Partner or its equivalent, on the terms and conditions of
such program.

     e.  Amendments in Writing.  This Agreement shall not be modified except by
         ---------------------
a written agreement dated subsequent to the date of this Agreement and signed on
behalf of Microsoft and NetIQ by their duly authorized representatives.

     f.  Assignment.  Neither Party may assign this Agreement, or any rights or
         ----------
obligations hereunder, whether by contract or by operation of law, except with
the express written consent of the other Party, and any attempted assignment by
either Party in violation of this Section shall be void.  For purposes of this
Agreement, an "assignment" by a Party shall be deemed to include, without
limitation, the following:  (i) a merger of the Party with a third party,
whether or not the Party is the surviving entity, where the third party has a
market capitalization, number of employees or past twelve months' revenues, as
of the end of the month preceding the announcement of the merger, equal to or
greater than forty percent (40%) of the Party's market cap, number of employees
or past twelve months' revenues; (ii) the acquisition of more than forty percent
(40%) of any class of the Party's voting stock (or any class of non-voting
security convertible into voting stock) by a third party or group (whether in a
single transaction or series of transactions); (iii) the acquisition of more
than thirty percent  (30%) of any class of the Party's voting stock (or any
class of non-voting security convertible into voting stock) by a third party or
group (whether in a single transaction or series of transactions), and after
such acquisition, the third party or group effects a change in management
control of the Party; or (iv) the sale of more than fifty percent (50%) of the
Party's assets (whether in a single transaction or series of transactions).  In
the event of such assignment or attempted assignment of the types listed in
subsections (i) through (iv) of this Section 14(f) by NetIQ, NetIQ shall notify
Microsoft of such transaction and include the name and description of the
parties to the merger, share purchase or asset purchase, as the case may be.
Microsoft shall review such transaction.  If Microsoft reasonably determines
that the parties involved in the transaction include a direct competitor to
Microsoft's platform business, Microsoft may elect to disapprove the assignment.
If Microsoft disapproves the assignment, NetIQ nonetheless may complete the
transaction.  If NetIQ completes the transaction and assigns the Agreement
despite the disapproval, Microsoft may elect to (a) terminate its marketing and
development obligations hereunder, subject to

                                       14
<PAGE>

continued payment of all unpaid Marketing Collaboration Support Fees due
hereunder; and/or (b) gain the right to use the Licensed Software and Licensed
Materials to create a fully functional NT Agent, by payment of fifty percent
(50%) of the fee which would otherwise be then due and payable under Section 3.
For purposes of this Section 14(f), the fee payable under Section 3 for the
period between the Effective Date and the first anniversary of the Street Date
shall be $175 Million. In the event Microsoft elects either or both of options
(a) or (b), above, NetIQ may elect to accelerate payment of the remaining unpaid
portion of the Licensing Fee.

     g.  Severability.  If any provision of this Agreement other than Section
         ------------
2(a) shall be held by a court of competent jurisdiction to be illegal, invalid,
or unenforceable, the remaining provisions shall remain in full force and
effect.  The Parties agree that if the provisions of Section 2(a) are held by a
court of competent jurisdiction to be illegal, invalid, or unenforceable, this
entire Agreement shall be rendered null and void, other than the confidentiality
provisions of Section 5(e).

     h.  Relationship of the Parties.  Neither this Agreement, nor any terms and
         ---------------------------
conditions contained herein, shall be construed as creating a partnership, joint
venture, agency, or franchise relationship.

     i.  Entire Agreement.  This Agreement, including Exhibits A, B, and C
         ----------------                             ----------  -     --
attached hereto, shall constitute the entire agreement between the Parties with
respect to its subject matter and merges all prior and contemporaneous
communications, both written and oral.  This Agreement shall not be modified
except by a written agreement signed on behalf of NetIQ and Microsoft by their
respective duly authorized representatives.

     j.  Waiver.  No waiver of any breach of any provision of this Agreement
         ------

same or any other provisions hereof, and no waiver shall be effective unless
made in writing and signed by an authorized representative of the waiving Party.
