1.0      DEFINITIONS

Capitalized terms in the Agreement have the following meanings.

 1.1 Code is computer programming code, including both Object Code and Source
Code.

         a.       OBJECT CODE is Code substantially in binary form, and includes
                  header files of the type necessary for use or interoperation
                  with other computer programs. It is directly executable by a
                  computer after processing or linking, but without compilation
                  or assembly. Object Code is all Code other than Source Code.
         b.       SOURCE CODE is Code in a form which when printed out or
                  displayed is readable and understandable by a programmer of
                  ordinary skills. It includes related source code level system
                  documentation, comments and procedural code. Source Code does
                  not include Object Code.

 1.2     DELIVERABLE is any item that ObjectSpace provides under this Agreement.

 1.3     DERIVATIVE WORK is a work that is based on an underlying work and that
         would be a copyright infringement if prepared without the authorization
         of the copyright owners of the underlying work. Derivative Works are
         subject to the ownership rights and licenses of a party or of others in
         the underlying work.

 1.4     DISTRIBUTORS are those authorized or licensed by Tivoli or IBM, or any
         of their Subsidiaries or Distributors, to license or distribute
         Products.

 1.5     ENHANCEMENTS are changes or additions, other than Error Corrections, to
         the Licensed Work.

         a.       BASIC ENHANCEMENTS are all Enhancements, other than Major
                  Enhancements, including those that support new releases of
                  operating systems and devices.
         b.       MAJOR ENHANCEMENTS provide substantial additional value and
                  are offered to customers for an additional charge.

 1.6     ERROR CORRECTIONS are revisions that correct errors and deficiencies
         (collectively referred to as "errors") in the Licensed Works.

 1.7     EXTERNALS are (1) any pictorial, graphic, and audiovisual works (such
         as icons, screens, sounds, and characters) generated by execution of
         Code, and (2) any programming interfaces, languages or protocols
         implemented in Code to enable interaction with other computer programs
         or the end user. Externals do not include the Code that implements
         them.

 1.8     LICENSED WORK is (1) ObjectSpace Voyager Code, in both Object Code and
         Source Code format, including any other material described in or that
         conforms to the description in the Attachment entitled "Description of
         Licensed Work," or that is delivered to Tivoli as the Licensed Work,
         including (but not limited to) Code, associated documentation, and
         Externals, and (2) Error Corrections and Enhancements.

 1.9     MORAL RIGHTS are personal rights associated with authorship of a work
         under applicable law. They include the rights to approve modifications
         and to require authorship identification.

         release of such product, whether or not branded by Tivoli or IBM, which
         contains some or all of the Licensed Work or a Derivative Work of a
         Licensed Work. A Product must add significant function or value to the
         Licensed Work contained in the Product by integrating, embedding,
         bundling or incorporating it into or with one or more of Tivoli's
         network or systems management products or suite of products (including
         IBM if such Tivoli products are transferred to it) such that the

         voting stock is owned or controlled, directly or indirectly, by another
         entity. If there is no voting stock, a Subsidiary is an entity during
         the time that more than 50% of its decision-making power is controlled,
         directly or indirectly, by another entity.

 1.12    TOOLS include devices, compilers, programming, documentation, media and
         other items required for the development, maintenance or implementation
         of a Deliverable that are not commercially available.

2.0      RESPONSIBILITIES OF OBJECTSPACE

                  promptly deliver such Tools (including updates to such Tools)
                  to Tivoli.

         c.       any updates to the following list. This list identifies any
                  commercially available devices, compilers, programming,

         c.       a completed certificate of originality with the Licensed Work,
                  and with each Enhancement to the Licensed Work, in the form
                  specified in the Attachment entitled

THE SECURITIES ACT OF 1933, AS AMENDED. ASTERISKS DENOTE THESE OMISSIONS.

                  "Certificate of Originality". Tivoli may suspend payments to
                  ObjectSpace for the Licensed Work if ObjectSpace does not
                  provide a properly completed certificate. Payment will resume
                  after Tivoli receives and accepts the certificate.

2.2      ObjectSpace will provide support for the Licensed Work as follows:

         a.       For the first full year following the Effective Date,
                  ObjectSpace will provide to Tivoli, at no charge, testing,
                  maintenance and support for the Licensed Work as described in
                  this Agreement, including the Attachment entitled, "Testing,
                  Maintenance and Support," as well as Basic and Major
                  Enhancements, and Error Corrections for the Licensed Work
                  beginning when Tivoli accepts the Licensed Work.
         b.       For the second full year following the Effective Date, Tivoli
                  may, at its option, elect to continue to purchase such
                  testing, maintenance, support, Enhancements (both Basic and
                  Major), and Error Corrections from ObjectSpace for an annual
                  fee of *.
         c.       Thereafter, Tivoli may, at its option, elect to continue to
                  purchase such testing, maintenance, support, Enhancements
                  (both Basic and Major), and Error Corrections from ObjectSpace
                  for the annual fee defined in this paragraph for so long as
                  Tivoli may require such support. ObjectSpace may charge Tivoli
                  an annual fee for such support not to exceed 105% of the fee
                  for the prior twelve month period.
         d.       ObjectSpace agrees to submit an invoice to Tivoli for such
                  support on an annual basis, and at least 30 days prior to the
                  beginning of each 12 month period. If Tivoli does not wish to
                  receive such support, Tivoli will so notify ObjectSpace.
         e.       If Tivoli cancels such support, Tivoli may reinstate it at a
                  later time by paying the support charges then in effect and an
                  additional fee. The additional fee will be equal to the
                  current annual support charges multiplied by the number of
                  annual periods for which support was interrupted. For purposes
                  of calculating the additional fee, portions of periods will
                  count as full periods.

2.3      ObjectSpace will:

         a.       participate in progress reviews, as requested by Tivoli, to
                  demonstrate ObjectSpace's performance of ObjectSpace's
                  obligations;
         b.       implement or continue suitable processes designed to help
                  prevent contamination by harmful code. ObjectSpace will
                  provide Tivoli notice if ObjectSpace suspects contamination;
         c.       have agreements with ObjectSpace's personnel and third parties
                  to perform obligations and to grant or assign rights to Tivoli
                  as required by this Agreement. On request, ObjectSpace will
                  provide Tivoli with evidence of these agreements;
         d.       maintain records to verify authorship of the Licensed Work for
                  4 years after the termination or expiration of this Agreement.
                  On request, ObjectSpace will deliver or otherwise make
                  available this information in a form specified by Tivoli;
         e.       not assign or transfer this Agreement or ObjectSpace's rights
                  under it, or delegate or subcontract ObjectSpace's
                  obligations, without Tivoli's prior written consent.
                  Notwithstanding the foregoing, ObjectSpace may assign or
                  otherwise transfer this


                                       4
<PAGE>


                  Agreement, or delegate its duties and obligations under
                  this Agreement, to a Subsidiary of ObjectSpace, without the
                  consent of Tivoli, but ObjectSpace will promptly notify
                  Tivoli of any such transfer, assignment or delegation. Any
                  other attempt to do so is void. In addition, ObjectSpace
                  specifically agrees that, prior to any planned sale by
                  ObjectSpace of the Licensed Work or sale by ObjectSpace of
                  its assets, which include the Licensed Work, including any
                  merger or other business combination, it will offer the
                  Licensed Work to Tivoli under the same terms and
                  conditions, including pricing, as ObjectSpace agreed on
                  with such prospective purchaser, on a first right of
                  refusal basis. If Tivoli elects not to exercise such right,
                  it will not unreasonably withhold its consent to an
                  ObjectSpace request under this section;
         f.       not provide any information to the media, or issue any press
                  releases or other publicity, regarding this Agreement or the
                  parties' relationship under it, without Tivoli's prior written
                  consent, except as otherwise set forth in Section 4.1 of this
                  Agreement; and
         g.       not disclose to a third party the terms of this Agreement or
                  the fact that Tivoli has licensed the Licensed Work, without
                  Tivoli's prior written consent, except as otherwise set forth
                  in Section 4.1 of this Agreement. ObjectSpace may, however,
                  make such disclosures (i) to its accountants, lawyers or other
                  professional advisors provided that any such advisor is under
                  a confidentiality obligation and (ii) as required by law
                  provided ObjectSpace obtains any confidentiality treatment for
                  it which is available.

2.4      If ObjectSpace fails to deliver the Licensed Work, Tivoli may either
         reduce any amounts due hereunder by an amount equal to the value not
         received, or have ObjectSpace reimburse Tivoli for the value not
         received, up to the total license fee set forth under Section 6 below.
         ObjectSpace also acknowledges that if it does not deliver the Licensed
         Work, Tivoli will suffer irreparable harm and will be entitled to all
         equitable remedies, including specific performance for the delivery of
         such Licensed Work.

         If ObjectSpace fails to deliver maintenance, support, Enhancements
         (both Basic and Major), and Error Corrections for a Licensed Work,
         Tivoli may either reduce any amounts due hereunder by an amount equal
         to the value not received, or have ObjectSpace reimburse Tivoli for the
         value not received, up to a total of the annual fee paid by Tivoli for
         the year in which such failure occurred.

3.0      TIVOLI OBLIGATIONS

3.1      Tivoli will provide ObjectSpace with the following Tivoli software
         programs, in the quantities specified, under the terms and conditions
         of its standard Tivoli End User License Agreement, a copy of which is
         attached to this Agreement. In consideration of the rights and licenses
         granted by ObjectSpace under this Agreement, Tivoli agrees to waive the
         one-time charge for such programs, and the first year's fee for
         maintenance and support for the such programs as described in the
         Tivoli End User License Agreement. After the first year, such
         maintenance and support will be available at Tivoli standard pricing.

         distribute, the Licensed Work in Source Code form, any Tools (in the
         event ObjectSpace delivers Tools under Section 2.1.b) and such
         Derivative Works, in any medium or distribution technology whatsoever,
         whether known or unknown, solely for Products. The rights and licenses
         granted by ObjectSpace to Tivoli hereunder also include the right of
         Tivoli to authorize or sublicense IBM, and any of Tivoli's and IBM's
         Subsidiaries, contractors, and consultants, to exercise any of the
         rights granted to Tivoli in this Section 5.1. Any such contractors and
         consultants will be under appropriate confidentiality restrictions no
         less restrictive than the CDA referenced on the first page of this
         Agreement.

 5.2     ObjectSpace also grants Tivoli a nonexclusive, worldwide, perpetual,
         irrevocable, paid-up right to sublicense and deliver a copy of the
         Source Code of the Licensed Work and Derivative Works thereof to third
         parties, including but not limited to Distributors, only in association
         with the


                                       6

         delivery and sublicensing of the Source Code of Products, and only
         if the Source Code is subject to the same restrictions as the Source
         Code of the Product. This includes the ability to sublicense the
         Source Code of a Product to fulfill an escrow obligation if its
         customer(s) requires Tivoli or IBM to place Source Code in an escrow
         account for maintenance and support purposes. The rights and
         licenses granted by ObjectSpace to Tivoli hereunder also include the
         right of Tivoli to authorize or sublicense IBM, and any of Tivoli's
         and IBM's Subsidiaries, to exercise any of the rights granted to
         Tivoli in this Section 5.2.

 5.3     ObjectSpace grants Tivoli a nonexclusive, worldwide, perpetual,
         irrevocable, paid-up license to reproduce, transfer, distribute
         internally and externally, and sublicense the Object Code only of the
         Licensed Work and its Derivative Works, and documentation, in any
         medium or distribution technology whatsoever, whether known or unknown,
         provided that such Object Code is distributed and sublicensed in
         conjunction with Products, and not in a stand-alone form. ObjectSpace
         grants Tivoli the right to authorize or sublicense others to exercise
         any of the rights granted to Tivoli in this Section 5.3.

 5.4     ObjectSpace grants Tivoli a nonexclusive, worldwide, perpetual,
         irrevocable, paid-up license to prepare Derivative Works of the
         Externals, and to use, execute, reproduce, display, perform, transfer,
         distribute, and sublicense the Externals and such Derivative Works, in
         any medium or distribution technology whatsoever, whether known or
         unknown. ObjectSpace grants Tivoli the right to authorize or sublicense
         others to exercise any of the rights granted to Tivoli in this Section
         5.4.

 5.5     The grant of rights and licenses to the Licensed Work and Tools
         includes a nonexclusive, worldwide, perpetual, irrevocable, paid-up
         license under any patents and patent applications that are owned or
         licensable by ObjectSpace now or in the future and are (1) required to
         make, have made, use and have used the Licensed Work or its Derivative
         Works or (2) required to license or transfer the Licensed Work or its
         Derivative Works; provided, however, that-a license to such patents
         would have been required to exercise these rights to the Licensed Work
         without regard to the Derivative Works. This license applies to the
         Licensed Work and its Derivative Works operating alone or in
         combination with equipment or Code. The license scope is to make, have
         made, use, have used, sell, license or transfer items, and to practice
         and have practiced methods, to the extent required to exercise the
         rights granted hereunder to the Licensed Work and Tools.

 5.6     Subject to ObjectSpace's ownership of the Licensed Work and Tools,
         Tivoli will own any Derivative Works it creates.

 5.7     ObjectSpace grants Tivoli a nonexclusive, worldwide, perpetual,
         irrevocable, paid-up license to use the names and trademarks
         ObjectSpace uses to identify the Licensed Work for Tivoli's marketing
         of the Products. ObjectSpace grants Tivoli the right to authorize or
         sublicense others to exercise any of the rights granted to Tivoli in
         this Section 5.7. If Tivoli's use of ObjectSpace's names and trademarks
         is improper and ObjectSpace provides Tivoli notice that ObjectSpace
         objects to it, Tivoli will take all reasonable steps necessary to
         resolve ObjectSpace's objections. ObjectSpace may reasonably monitor
         the quality of products bearing its trademark under this license.

SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 OF
THE SECURITIES ACT OF 1933, AS AMENDED. ASTERISKS DENOTE THESE OMISSIONS.

 5.8     Any goodwill attaching to Tivoli's trademarks, service marks, or trade
         names belongs to Tivoli and this Agreement does not grant ObjectSpace
         any right to use them. Tivoli may state that ObjectSpace has provided
         the Licensed Work. ObjectSpace may state that it has licensed the
         Licensed Work to Tivoli.

 5.9     Subject to agreement on the license fee to be paid to ObjectSpace,
         ObjectSpace agrees that the rights and licenses granted by ObjectSpace
         hereunder also include the right of Tivoli and IBM to exercise any of
         the rights granted to Tivoli in this Section 5 on products other than
         the Product.

         ObjectSpace further agrees that any such license fee will be
         reasonable, nondiscriminatory, and consistent with the license fee paid
         by other similarly situated customers.

 6.0     PAYMENT

 6.1     For the rights and licenses received, Tivoli will pay ObjectSpace a
         total license fee of * in two payments, as follows:

         On January 31, 1998                                           *

 6.2     ObjectSpace will submit invoices to Tivoli for the above amounts prior
         to the payment date. After Tivoli's receipt of a valid invoice, Tivoli
         will pay ObjectSpace the amounts due upon the above dates.

 6.3.    For support as set forth in Section 2.2, ObjectSpace agrees to submit
         an invoice to Tivoli for such support on an annual basis, and at least
         30 days prior to the beginning of each 12 month period. After Tivoli's
         receipt of a valid invoice, Tivoli will pay ObjectSpace the amounts due
         within 30 days. If Tivoli does not wish to receive such support, Tivoli
         will so notify ObjectSpace.

 6.4     All invoices will include the following information:

         a. ObjectSpace's company and remit to address; and
         b. Reference to this Agreement by its number and its date.

 6.5     All invoices will be addressed to the designated Contract Coordinator
         at Tivoli Systems, Inc. and sent (with a copy to the Tivoli Technical
         Coordinator) to the following address:

         9442 Capital of Texas Highway
         Austin, Texas 78759

 6.6     Each party will be solely responsible for any taxes it incurs, directly
         or indirectly, associated with its performance of this Agreement.

 6.7     The payments defined in this Section fully compensate ObjectSpace for
         its performance under, and for the rights and licenses granted in, this
         Agreement.

 7.0     TESTING

 7.1     ObjectSpace will perform the following tests prior to each delivery of
         the Licensed Work:

         a.   component testing;
         b.   functional verification testing; and
         c.   compatibility testing.

         Upon Tivoli's request, the details of such testing will be mutually
         agreed to by the parties.

 7.2     ObjectSpace will provide to Tivoli concurrent with each delivery of the
         Licensed Work and Tools all test results, test scenarios, test cases,
         and test reports associated with the pre-delivery testing.

 7.3     Upon receipt of the Licensed Work by Tivoli, Tivoli may evaluate the
         Licensed Work for a period of 30 days and perform such tests as Tivoli
         deems appropriate to determine whether:

         a.       the Licensed Work meets the specifications described in the
                  Attachment entitled "Description of Licensed Work";
         b.       the Licensed Work executes repetitively within the system
                  environment described in the Attachment entitled "Description
                  of Licensed Work"; and
         c.       Tivoli can successfully execute to completion all functional
                  and system test scenarios developed by Tivoli.

         Tivoli's testing does not relieve ObjectSpace of its obligations under
         this Agreement. Tivoli has no obligation to identify errors.

 8.0     REPRESENTATIONS AND WARRANTIES

 8.1     ObjectSpace makes the following ongoing representations and warranties:

         a.       ObjectSpace has full legal rights to grant the rights granted

                  in this Agreement;
         c.       there are no liens, encumbrances or claims pending or

                  documentation, and any sales and marketing materials
                  provided by ObjectSpace;
         g.       the fully commented Source Code that ObjectSpace provides

                  products (for example, hardware, software and firmware) with
                  which the Licensed Work is designed to be used; and
         i.       neither the Licensed Work nor the Tools are contaminated by
                  harmful code.

         ObjectSpace will immediately provide Tivoli written notice of any
         change that may affect its representations and warranties.

 8.2     Except as provided above, anything either party provides to the other
         related to this Agreement is "AS IS", without warranty of any kind.

 9.0     INDEMNIFICATION AND LIABILITY

 9.1     BY OBJECTSPACE. ObjectSpace will be responsible for and will indemnify
         Tivoli, IBM, and any of their Subsidiaries, from any and all damages,
         settlements, costs, expenses and liabilities of any type whatsoever, if
         a third party makes a claim against Tivoli, IBM, or any of their
         Subsidiaries based on an actual or alleged:

         a.       failure by ObjectSpace, to the extent not caused by Tivoli, to
                  perform ObjectSpace's obligations under this Agreement;
         b.       breach of ObjectSpace's representations and warranties;
         c.       assertion or claim that a person or entity other than
                  ObjectSpace has Moral Rights in the Licensed Work;
         d.       failure by ObjectSpace to comply with government laws and
                  regulations; or
         e.       infringement by ObjectSpace, the Licensed Work or Tools of
                  patents, copyrights, trademarks, trade secrets, and other
                  intellectual property rights, except to the extent such a
                  claim is based solely on the combination, operation or use of
                  the Licensed Work with programs or data not supplied by
                  ObjectSpace, if such infringement would have been avoided but
                  for the combination, operation or use of the Licensed Work
                  with such other programs or data.

         a.       promptly provide ObjectSpace notice of any such claim; and

CONFIDENTIAL INFORMATION HAS BEEN OMITTED FROM THIS DOCUMENT AND FILED
SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 OF
THE SECURITIES ACT OF 1933, AS AMENDED. ASTERISKS DENOTE THESE OMISSIONS.

         a.       obtain the necessary rights for Tivoli, IBM, and any of their
                  Subsidiaries and Distributors, and their respective customers
                  to continue to distribute, license, otherwise transfer and use
                  the Licensed Work on an uninterrupted basis and exercise all
                  rights granted in the Licensed Work and Tools; or
         b.       modify the Licensed Work and Tools at ObjectSpace's expense to
                  resolve the claim. This modified Licensed Work will comply
                  with the Attachment entitled "Description of Licensed Work."

         If ObjectSpace is not able to do either within a reasonable period of
         time, Tivoli may terminate this Agreement for ObjectSpace's breach.

         ObjectSpace's total liability for indemnification under this Section
         9.1 is limited to *.

 9.2     BY TIVOLI. If a claim is made against ObjectSpace by a third party
         based upon the distribution of Products provided for under this
         Agreement, Tivoli will be responsible for and will indemnify
         ObjectSpace from any and all damages, settlements, costs, expenses and
         liabilities of any type whatsoever regarding such third party claim,
         with the exception of those activities for which ObjectSpace bears
         responsibility under Section 9.1 of this Agreement, and provided
         ObjectSpace gives Tivoli prompt written notice of any such claim,
         together with the full authority for and cooperation with such a
         defense and any settlement negotiations.

         Tivoli's total liability for indemnification under this Section 9.2 is
         limited to *.

 9.3     In addition to any remedies specified in this Agreement, either party
         may pursue any other remedy it may have in law or in equity. Regardless
         of the type of claim, neither party is liable to the other for
         indirect, incidental, special, or consequential damages including, but
         not limited to, lost profits or revenues, under any part of this

         not apply to (a) ObjectSpace's liabilities for indemnity above, or (b)
         Tivoli's liabilities for indemnity above. Other than with respect to
         Tivoli's liability for indemnity above, Tivoli's total liability is
         limited to payments due to ObjectSpace under this Agreement; provided,
         however, that Tivoli's total liability with respect to a violation of
         the license grant set forth in Sections 5.1 or 5.3 is limited to *.

 10.0    TERM AND TERMINATION

 10.1    This Agreement begins on the Effective Date and has a term of one year
         unless terminated sooner under the terms of this Agreement; provided,
         however, that this Agreement will be extended automatically for
         additional one year periods upon the anniversary of the Effective Date.

 10.2    Either party may terminate this Agreement for the other's material
         breach by providing the breaching party with a written notice that
         describes the breach. The termination will become effective 45 days
         after receipt of the notice unless the breach is cured within that 45
         day period. However, if the breach (other than a breach for failure to
         deliver the Licensed Work) by its nature, cannot be remedied in 45
         days, but can be remedied in a reasonable time thereafter, the


                                       11
<PAGE>


         breaching party will take reasonable and diligent steps to remedy it,
         notify the other party of the action plan, progress towards completion,
         and complete such remedial action promptly. In such event, the notice
         period will be suspended while the breaching party takes these actions.

 10.3    Tivoli may, for its convenience, terminate this Agreement on 30 days'
         written notice to ObjectSpace. After the Agreement has been in effect
         for 4 years from the Effective Date, ObjectSpace may, for its
         convenience, terminate this Agreement on twelve months' written notice
         to Tivoli.

 10.4    Expiration of this Agreement does not affect any licenses granted in
         this Agreement for the Licensed Work or Tools. Termination of this
         Agreement does not affect any licenses granted in this Agreement for
         the Licensed Work or Tools delivered or due to Tivoli prior to the
         effective date of termination.

 10.5    Subject to Subsection 10.4, any provisions of this Agreement that by
         their nature extend beyond termination or expiration will survive in
         accordance with their terms. These include Section 5, "LICENSE GRANTS,"
         Section 8.0, "REPRESENTATIONS AND WARRANTIES," Section 9.0,
         "INDEMNIFICATION AND LIABILITY," and Section 12, "GENERAL." These terms
         will apply to either party's successors and assigns.

         Neither party will assume or create obligations for the other. Each
         party is responsible for the direction and compensation of its
         employees.

12.2     FREEDOM OF ACTION. Each party may have similar agreements with others.
         Each party may design, develop, manufacture, acquire or market
         competitive products and services, and conduct its business in whatever
         way it chooses. Tivoli is not obligated to announce or market any
         products or services. Tivoli does not guarantee the success of its
         marketing efforts. Tivoli will independently establish prices for its
         products and services.

12.3     RELIANCE. Neither party relies on any promises, inducements or
         representations made by the other or expectations of more business
         dealings, except as expressly provided in this Agreement. This
         Agreement accurately states the parties' agreement.

12.4     COMPLIANCE WITH APPLICABLE LAWS. Each party will comply with all
         applicable laws and regulations at its expense including, to the extent
         applicable, Executive Order 11246 on Equal Employment Opportunity, as
         amended, the Occupational Safety and Health Act of 1970, as amended,
         and the Americans With Disabilities Act of 1990, as amended. This also
         includes all applicable government export and import laws and
         regulations.

12.5     CONFIDENTIAL INFORMATION. The parties agree that information exchanged
         under this Agreement that is considered by either party to be
         confidential information will be subject to the terms of the CDA
         referenced on the first page of this Agreement and its Supplements. In
         addition, ObjectSpace will not provide Tivoli with any information
         which may be considered confidential information of any third party
         unless provided under the CDA. The obligations set forth in the CDA
         with regard to confidential information will not limit or preclude the
         exercise of the licenses granted in this Agreement.

12.6     COPYRIGHT. Any publication by Tivoli of the Licensed Works or a
         Derivative Work thereof will contain an appropriate copyright notice,
         as determined by Tivoli. Tivoli will retain any copyright notices
         ObjectSpace has on the Licensed Work.

         ObjectSpace will enforce and maintain its copyright protection in the
         Licensed Works. Tivoli is not responsible for enforcing and maintaining
         such copyright protection. However, ObjectSpace authorizes Tivoli to
         act as ObjectSpace's agent in the copyright registration of the
         Licensed Works. At Tivoli's request, ObjectSpace agrees to provide
         Tivoli reasonable assistance in registering any Product.

12.7     ORDER OF PRECEDENCE. If there is a conflict among the terms of this
         base License Agreement and its Attachments, the terms of this base
         License Agreement prevail over those of the Attachments, unless the
         parties expressly indicate in the Attachments that particular terms
         within the Attachments prevail. Terms in Tivoli's purchase orders and
         ObjectSpace's invoices are void.

12.8     HEADINGS. The headings of this Agreement are for reference only. They
         will not affect the meaning or interpretation of this Agreement.

12.9     COUNTERPARTS. This Agreement may be signed in one or more counterparts,
         each of which will be considered an original, but all of which together
         form one and the same instrument.

12.10    AMENDMENT AND WAIVERS. For a change to this Agreement to be valid, both
         parties must sign it. No approval, consent or waiver will be
         enforceable unless signed by the granting party. Failure to insist on
         strict performance or to exercise a right when entitled does not
         prevent a party from doing so later for that breach or a future one.

12.11    ACTIONS. Neither party will bring a legal action relating to the
         subject matter of this Agreement, against the other more than 2 years
         after the cause of action arose, except in the case of indemnification
         for infringement, in which case this period runs for 2 years after the
         award or settlement was made.

12.12    DISPUTE RESOLUTION. Both parties will act in good faith to resolve
         disputes prior to instituting litigation. Each party waives its rights
         to a jury trial in any resulting litigation.

12.13    GOVERNING LAW. This Agreement will be governed by the substantive law
         of the State of Texas applicable to contracts executed in and performed
         entirely within that State, without regard to choice of law principles,
         regulations, or statutes of this or any other jurisdiction. The United
         Nations Convention on Contracts for the International Sale of Goods
         does not apply. ObjectSpace will, upon written notice from Tivoli,
         submit to personal jurisdiction in any forum where Tivoli is sued for
         claims related to this Agreement.
