to do so without violating obligations to any Third Party, and it is understood
that such Outside Technology shall not be deemed to be Program Technology;
provided, however, that information, data, materials or inventions made in the
Research Program shall be deemed to be Program Technology whether or not such
information, data, materials or inventions were made using Outside
Technology.   Notwithstanding the above,
TDCC will not knowingly in collaboration with any Third Party conduct research
activities using Combinatorial Chemistry methods with respect to the active
projects being conducted with Symyx in the Field applicable at that time,
provided, however, that TDCC shall not be precluded from engaging in optimization
projects in collaboration with any Third Party, and provided that this sentence
shall not restrict the use by TDCC of Discovery Tools Systems purchased and
licensed hereunder or previously purchased and licensed from Symyx.  Notwithstanding anything herein to the
contrary, a TDCC Affiliate shall not be limited in its research activities,
unless TDCC directs the research or owns the research results.  2.3.4*  2.3.5*  2.4Changes
to Fields.  The initial Fields
activated in the Research Plan shall be those identified in Exhibit A.  During the Program Term, TDCC and Symyx Tech
may agree to conduct research in one or more additional Fields (including one
or more of the Secondary Field), or to amend Exhibit A to create a new Field or
to delete Fields that are not contemplated to be activated. Those Fields that
are not currently active but which may be included in a Research Plan upon
request of TDCC are Secondary Fields as set forth in Exhibit B.  In the event that TDCC and Symyx Tech agree
to a new Field, or a new project within the Fields, this will be documented by
appropriate written modifications to the Research Plan, including the criteria
in Schedule 2.1, and appropriate modifications in writing to the staffing
plan of the Research Program activities in connection with such Field.  TDCC and Symyx Tech may also agree to
discontinue activity in one or more Fields by written modifications to the
Research Plan.  In the event the parties
determine to discontinue research activities in any particular Field in which
research was active during the Program Term, such Field shall no longer be
within the Field in Exhibit A as of the date research activities are
discontinued, but may revert to a Secondary Field only if the parties mutually
agree in writing that this Field may be reactivated at a future date.*  Appropriate
modifications or adjustments to staffing of the Research Program will be agreed
to reflect any changes in activity of the Fields.  The Advisory  Confidential  12


Committee
described in Section 3.3 shall in general provide direction for any
changes in Fields and make formal recommendations to the Executive
Committee.  Symyx Tech shall not
unreasonably refuse to agree to changes proposed by TDCC to change activity in
the Fields.  TDCC shall not unreasonably
refuse to agree to adjustments in staffing of the Research Program proposed by
Symyx Tech as a consequence of any changes in the activity of the Fields.  TDCC may add to the Fields in connection with
projects to be activated, with the consent of Symyx Tech, such consent not to
be unreasonably withheld.  Symyx Tech may
delete from the Fields in connection with projects not planned to be activated,
with the consent of TDCC, such consent not to be unreasonably withheld.  2.5Secondary
Fields.  Symyx may engage in
discussions with Third Parties regarding possible collaboration in any
Secondary Field.  Prior to making a
formal proposal to a Third Party to collaborate in an Secondary Field, Symyx
will notify TDCC and TDCC shall give written notice to Symyx within * informing
Symyx whether TDCC is interested in negotiating with Symyx to activate a
project in such Secondary Field.  In the
event TDCC notifies Symyx that it is interested, good faith negotiations shall
commence promptly and continue for a period not to exceed * from the giving of
such notice by TDCC to activate a collaboration in such Secondary Field.  If TDCC and Symyx agree to establish such a
collaboration, then such Secondary Field shall become part of the Fields (and
shall no longer be a Secondary Field). 
If the parties have not agreed to establish such a collaboration within
such * period, Symyx shall be free to engage in a collaboration in such
Secondary Field with a Third Party, and in such event, such Secondary Field
shall thereafter be excluded from both the Secondary Fields and the
Fields.  Notwithstanding the above, in
the event that TDCC, during the Program Term, knowingly in collaboration with
any Third Party conduct research activities using Combinatorial Chemistry
methods with respect to any of the Secondary Fields, TDCC shall promptly notify
Symyx in writing and such Secondary Field shall thereafter be excluded from
both the Secondary Fields and the Fields, provided that this sentence shall not
apply to the use by TDCC of Discovery Tools Systems purchased and licensed
hereunder or previously purchased and licensed from Symyx.  2.6Research
Records.  Symyx Tech and TDCC shall
maintain records of the Research Program (or cause such records to be
maintained) in sufficient detail and in good scientific manner as will properly
reflect the work done and results achieved in the performance of the Research
Program (including information sufficient to establish dates of conception and
reduction to practice of inventions). 
Access to such records shall be granted as provided in Sections 8.9 and
10.2.  2.7Development
and Commercialization of Agreement Compounds and Products.  TDCC and its Affiliates shall be responsible
for all expenses incurred for the development and commercialization of
Agreement Compounds and Products by TDCC and its Affiliates under the terms of
this Agreement.  2.8Third
Party Claims.  In the event that TDCC
or Symyx receives a written notice from any Third Party alleging patent infringement,
misappropriation of trade secrets, or other violation of intellectual property
rights, based on research activities in the Research Program or potential
commercialization of results of the Research Program, such party shall promptly
notify the other.  Symyx and TDCC shall
use commercially reasonable efforts to determine how the objectives of any  Confidential  13


Research Program
involved may be achieved without excessive risks or costs, including potential
settlement with the Third Party.  Symyx
and TDCC, upon advice of counsel, shall each have the right, in its discretion,
to cease to conduct any research activities that are the subject of such claim
without liability to the other party; provided, however, that if TDCC or Symyx
acquires a license to permit the conduct of such activities, and/or if TDCC and
Symyx mutually agree in writing upon terms of indemnification for conduct of
such activities, then the parties will resume or continue, as appropriate, such
activities in accordance with the Research Plan and the terms and conditions of
this Agreement.  In the event a party
decides to cease to conduct any research activities pursuant to this Section 2.8,
Symyx and TDCC shall endeavor to change or modify the Fields as provided in Section 2.4
in a manner that maintains the value of the Research Program to TDCC. In the
event Symyx or TDCC decides to cease to conduct any research activities
pursuant to this Section 2.8, such cessation is a material portion of the
Research Program (at least*) and the parties are unable to agree upon changes
or modifications of the Fields as provided in Section 2.4 in a manner that
maintains the value of the Research Program to TDCC, TDCC may elect by written
notice to Symyx to limit the number of FTEs in the Research Program (and its
corresponding payment obligation pursuant to Section 8.1) to those FTEs
whose work was not subject to the cessation.  Article 3

LICENSES  4.1License
to TDCC.  4.1.1License
in the Fields.  Subject to the terms
and conditions of this Agreement, Symyx agrees to grant, and hereby grants, to
TDCC, and TDCC hereby accepts an exclusive (even as to Symyx), worldwide,
royalty-bearing license under Symyxs interest in the Program Technology to make,
have made, import and use Agreement Compounds to develop, make, have made, use,
sell, offer for sale, and import Products within the scope of the corresponding
Fields.  For purposes of clarification,
it is understood that for so long as TDCC retains this license, TDCC shall have
the non-exclusive right to use Library Compounds and Confidential Information
received from Symyx in the course of the Research Program, as well as Program
Technology, to develop Agreement Compounds both during and after the Program
Term and to make, have made, import and use such Agreement Compounds to
develop, make, have made, use, sell, offer for sale, and import Products within
the scope of the corresponding Fields. 
It is further understood and agreed that the licenses set forth in this Section 4.1.1
shall apply only to the Fields as such Fields exist at the time any particular
Program Know How is developed or any particular Program Patent is conceived and
reduced to practice (as defined in Section 1.30.2). A license arising with
respect to particular Program Technology as  Confidential  17


applicable to the
then-existing Field shall continue to apply to such Field even if the scope of
the Field is subsequently amended such that it no longer includes the Field
that was in place at the time the license initially arose. It is understood and
agreed that no license is granted to TDCC under Symyx Patents or other patents
owned or controlled by Symyx that are not Program Patents, except as provided
in Section 4.1.2 or 4.1.3.  4.1.2*  4.1.3Limited
Immunity with Respect to Symyx Patents.  *  4.2Sublicenses.  Subject to the terms and conditions of this
Agreement, TDCC shall have the right to grant sublicenses under the rights
granted in Section 4.1 above to Affiliates of TDCC and TDCC Joint
Ventures; provided that the terms of each such sublicense shall be consistent
with the terms of this Agreement. It is understood that any such sublicense
shall be subject and subordinate to the terms and conditions of this Agreement,
and that TDCC shall remain responsible for all applicable financial and other
obligations under this Agreement for each such Affiliate sublicensed, including
without limitation milestone and royalty payments due to Symyx hereunder with
respect to development and sales of Products. Subject to the terms and
conditions of this Agreement, TDCC or an Affiliate of TDCC shall also have the
right to grant sublicenses under the rights granted in Sections 4.1.1 and 4.1.2
above to one or more Third Parties (other than TDCC Joint Ventures); provided
that any revenue received from such a Sublicensee for such grant shall be
shared in accordance with Section J2.1(iv) or J3.1 of Exhibit J, as
applicable.   TDCC shall provide to Symyx
Tech at least the following information with respect to each Sublicensee or
Affiliate or TDCC Joint Venture sublicensed: (i) the identity of each
Sublicensee or Affiliate or TDCC Joint Venture sublicensed, (ii) a summary
of the rights granted as to both subject matter and territory; and (iii) a
summary of the Confidential Information of Symyx and Program Technology
furnished to each Sublicensee or Affiliate or TDCC Joint Venture. No sublicense
granted by TDCC or an Affiliate to a Third Party may be further assigned or
further transferred by any Sublicensee without the prior written consent of
Symyx Tech, which consent shall not be unreasonably withheld; provided, any
such a sublicense may be further assigned by a Sublicensee without the consent
of Symyx Tech in connection with a transfer of substantially all the business
of such Sublicensee to which such sublicense relates.  4.3Third
Party Rights.  It is understood that
Symyx is in the business of conducting materials discovery, research and
development with Third Parties, and that Symyx will continue to grant Third
Parties rights to acquire licenses related to compounds and materials derived
from such research.  It is possible that
a Third Party may acquire rights from Symyx with respect to one or more
compounds or materials that are solely owned by Symyx or jointly owned by Symyx
and a Third Party and which were made and designed independently of Symyxs
activities in the Research Program. 
Accordingly, Symyxs grant of rights to TDCC under Section 4.1 does
not include (i) rights that are covered by a patent application with
respect to such a compound or material that was made and designed independently
of activities in the Research Program and is solely owned by Symyx or a Third
Party  Confidential  18


or jointly owned
by Symyx and a Third Party, where such patent application was filed by a Third
Party (either alone or jointly with Symyx) prior to the filing by TDCC (either
alone or jointly with Symyx) of a patent application with respect to such a
compound or material, or (ii) rights which are subject to a license,
option, or other rights that Symyx has granted to a Third Party prior to the
Effective Date.  It is understood and
agreed that, even if Symyx complies with its obligations under this Agreement,
research for Third Parties in the course of Symyxs other business activities
may result in patent applications and patents owned by Third Parties, or owned
jointly by Symyx and such Third Parties, which could conflict with patent
applications and patents owned by TDCC, or jointly owned by TDCC and Symyx,
under this Agreement.  Symyx shall use
its good faith commercially reasonable efforts to avoid such conflicts.  In the event that conflicts arise between
rights granted to TDCC in the Field and rights granted by Symyx outside the
Field, Symyx agrees to use commercially reasonable efforts to promote a
resolution of the conflict between TDCC and the Third Party via a cross-license
or other arrangement acceptable to the parties involved.  It is understood that, except to the extent
that TDCC is damaged as a proximate result of a material breach by Symyx of
Sections 2.3, 4.1.1, 4.1.2 or 13.2 of this Agreement, then Symyx shall have
no liability under this Agreement with respect to any such conflict.  4.4Joint
Inventions*. TDCC, TDCCs Affiliates, Symyx, and Symyxs Affiliates shall
each have the right to use Joint Inventions for internal research purposes *;
provided, however, that, subject to Section 4.1.2 and prior obligations
arising under the CRLA, Symyx shall have the sole right to commercially exploit
such Joint Inventions *.  It is further
understood and agreed that Symyx shall have the right to grant Third Parties
licenses under Joint Inventions * that are exclusive even as to TDCC and
Symyx.  If Symyx grants such a license
that is exclusive even as to TDCC and Symyx, Symyx shall promptly notify TDCC
in writing.  Symyx and TDCC shall negotiate
in good faith to determine the added value attributable to TDCC and the Research
Program.  *  It is understood and agreed that Confidential
Information received by Symyx from TDCC or developed by Symyx for TDCC shall be
subject to all applicable provisions of Article 12 of this Agreement.  4.5Retained
Rights.  4.5.1Sole
Inventions Outside the Fields. 
Subject to the license to Combinatorial Chemistry Technology in Section 4.6,
rights under Section 4.1.2 and any prior obligations under the CRLA, TDCC
and Symyx shall each retain all rights * in and to inventions and discoveries
invented or made solely by such party in the course of the Research Program,
provided that nothing contained herein shall limit TDCCs use of Discovery
Tools Systems purchased and licensed hereunder or previously purchased and
licensed from Symyx.  4.5.2Symyx
Research.  Notwithstanding the
licenses and rights granted by Symyx in this Article 4, Symyx shall retain
the right to make, have made, and use any Library Compounds or Agreement
Compounds, and use or practice any processes or methods developed by or on
behalf of Symyx in the course of performing the Research Program, for its own
internal research to develop, improve and validate its tools and Combinatorial
Chemistry Technology.  Confidential  19


4.6Combinatorial
Chemistry.  TDCC agrees to grant, and
hereby grants, to Symyx an irrevocable, royalty-free non-exclusive license,
with the right to grant and authorize sublicenses, under TDCCs interest in
Combinatorial Chemistry Technology made or invented solely by TDCC in the
course of the Research Program, to conduct activities using Combinatorial
Chemistry.  TDCC, TDCCs Affiliates,
Symyx and Symyxs Affiliates shall each have the right to use Combinatorial
Chemistry Technology made or invented jointly by TDCC and Symyx in the course
of the Research Program for internal research purposes; provided, however, that
Symyx shall have the sole right to grant and authorize licenses and sublicenses
to Third Parties under such Combinatorial Chemistry Technology.  It is understood that this Section 4.6
shall not apply to any inventions conceived and reduced to practice by TDCC
independent of the Research Program and without use of, or reference to,
Combinatorial Chemistry Technology owned by Symyx, other than the use of and
reference to the Discovery Tools Systems, if any, licensed or sold to TDCC as
set forth in Article 7 or under prior agreements.  Nothing herein shall be construed to obligate
TDCC to grant to Symyx the right to use or sublicense background rights in technology
of TDCC that existed prior to the Effective Date or results of Independent TDCC
Research.  4.7Limited
Use Outside of Field.  Except as the
parties may otherwise expressly agree in writing, TDCC shall not use or sell,
or authorize the use or sale of, Program Technology developed solely or jointly
by Symyx, or any Agreement Compound or Library Compound, except (i) in
relation to the manufacture, use or sale of Products within the corresponding
Field or Fields in accordance with the license granted by Symyx in
Sections 4.1.1, or (ii) in accordance with Section 4.1.2.  It is understood that this Section 4.7
does not preclude TDCC from the use or sale or authorizing the use or sale of
compounds developed independently by TDCC without the use of Library Compounds,
Confidential Information of Symyx, or Program Technology, or limit TDCCs use
of Discovery Tools Systems purchased and licensed hereunder or previously
purchased and licensed from Symyx or limit the use of workflows, instruments
and equipment developed in the normal course of business of TDCC and its
Affiliates and TDCC Joint Ventures (provided that the use of such workflows,
instruments and equipment shall be licensed by Symyx only as expressly set
forth in this Agreement).  4.8*  4.9*  4.10General
Provisions with respect to Rights and Fields.  For the avoidance of doubt, it is understood
that as a general proposition, all licenses and rights that arise under this
Agreement, including without limitation, Sections 4.1, 4.2, and 4.4, with
respect to Program Technology with respect to any particular Field continue
even though the scope of the Field as subsequently amended does not include
such particular Field or includes other Fields. It is the intent of the parties
that this Agreement be construed such that the rights and licenses hereunder
are consistent with the scope of the Fields at the time any particular Program
Know How is developed, any particular Lead Compound is identified, or any
particular Program Patent is conceived and reduced to practice (as defined in Section 1.30.2).  By way of illustration, the above principles
shall apply such that TDCCs rights with respect to a particular Agreement
Compound, applicable to a particular Field as of the  Confidential  20


time such
Agreement Compound arose, apply equally to any modifications TDCC might make to
such Agreement Compound, even if such modifications are made after the Field
definition has been changed.  Article 5
SOFTWARE  5.1Deployment.  Symyx DTools shall provide a minimum of * and
up to * FTE years of personnel to deploy the Software during the Program Term
within TDCC and its Affiliates in accordance with a Software Deployment Plan
attached hereto as Exhibit G (Software Deployment Plan), as follows:  *. 
TDCC shall provide Symyx with at least twelve (12) months notice a
forecast of the staffing levels for the Software Deployment Plan (other than
staffing for 2005 and 2006, which shall be as set forth above)(e.g., if there
are expected to be less than * as of January 1, 2007, TDCC shall so notify
Symyx no later than January 1, 2006) and at least six (6) months notice
with respect to actual staffing levels for the Software Deployment Plan.   Notwithstanding any other provision of this
Agreement, Symyx shall not, without its consent, be required to perform
activities other than in accordance with the Software Deployment Plan or
utilize a number of FTEs in excess of the number of FTEs specified above. Symyx
DTools shall use efforts that are reasonable in the circumstances and
consistent with professional standards applicable to the research and
development software business to conduct activities in accordance with the
Software Deployment Plan.  TDCC contemplates
that it will provide an average of * FTEs per year during the Program Term in
support of the Software Deployment Plan, but such number may be adjusted by
mutual consent, such consent not to be unreasonably withheld.  Annual Program Goals for each twelve (12)
month period commencing on January 1st of the Program Term for
the Software Deployment Plan will be established pursuant to Section 3.5.  Symyx shall for the duration of the Program
Term and any extension thereof use commercially reasonable efforts to provide
such support services for the Software as it generally provides to its
customers, as further described in Exhibit G. 
Such support services shall be without additional charge to TDCC (other
than the payments set forth in Sections 8.2 and 8.4 hereunder).  Symyx will take reasonable steps to
facilitate the organization and operation of user groups (Renaissance user
groups for all interested Symyx customers consistent with Symyxs practices as
of the Effective Date) for Software during the Program Term, if TDCC requests.  5.2Software
License.  Symyx Dtools shall provide
the Software to TDCC (and to Affiliates designated by TDCC) on or before the

Research and Development Activities. Symyx does not provide, and TDCC and its
Affiliates shall be responsible to secure or use their own Oracle database[s]
and operating system[s] and appropriate licenses thereto, as well as licenses
for any Third Party software TDCC wishes to use (e.g., Spotfire).  TDCC will report to Symyx the number of users
of the Software, within * at the request of Symyx, but not more frequently than
*.  Confidential  21


5.3Developers
Kit Software License.  Symyx Dtools
shall provide the Developers Kit Software to TDCC (and to Affiliates
designated by TDCC) on or before the beginning of the Program Term and shall
provide documentation for same in accordance with the Software Deployment Plan
and Annual Program Goals, and Symyx hereby grants to TDCC a worldwide,
nonexclusive, nontransferable, nonsublicensable (except as provided in Section 5.10)
right to install and use * copies of the Developers Kit Software, in object
code format, during the Program Term, to create Software Customizations solely
for TDCCs Internal Research and Development Activities.  Symyx and TDCC agree that TDCC will retain
ownership of the Software Customizations (and the intellectual property rights therein)
it creates using the Developers Kit Software hereunder.  With respect to any such Software
Customizations, TDCC will either (i) rely solely on trade secret protection, or
(ii) agrees to grant and hereby grants to Symyx a nonexclusive, worldwide, perpetual,
irrevocable, paid-up, transferable, sublicenseable right to make, have made,
modify, copy, create derivative works based on, use, offer to sell, sell,
export and import any Software Customizations to the extent these are claimed
in any patent application filed by TDCC to the extent TDCC may grant rights to
Symyx. In the event TDCC elects (ii) above with respect to any Software
Customization, TDCC will provide Symyx the opportunity to review and comment on
associated patent application drafts at least * days prior to filing or
prosecuting any application for a patent with respect to any Software
Customization, and shall promptly notify Symyx in the event any patent
publishes or is issued with claims covering any Software Customization.  Notwithstanding the preceding, it is
understood and agreed that U.S. provisional patent applications (filed
under 35 U.S.C.§111(b)) may be filed by TDCC without review and comment in
order to obtain the earliest possible filing date, but TDCC will use
commercially reasonable efforts to seek review and comment from the other party
prior to filing such provisional patent applications.  Furthermore, for clarification, it is
understood that the license to Symyx under this Section shall not apply to
any inventions conceived and reduced to practice by TDCC independent of the
Developers Kit Software and without use of confidential information owned by
Symyx.  In addition, nothing herein shall
be construed to obligate TDCC to grant to Symyx the right to use or sublicense
background rights in technology of TDCC that existed prior to the Effective
Date.  TDCC also is not obligated to
disclose to Symyx Software Customizations kept as a trade secret. TDCC
will report to Symyx the number of users of the Developers Kit Software, within
* at the request of Symyx, but not more frequently than *.  5.4Sample

been extended pursuant to Section 6.4, directly or indirectly, provokes,
requests, or otherwise attempts to initiate a reexamination proceeding in the
United States Patent and Trademark Office with respect to any claim in such
specified Symyx Combinatorial Patent Rights as to which TDCC has license rights
under Section 6.1, or files a notice of opposition or participates in any
opposition against any claim in any Symyx Combinatorial Patent Rights as to
which TDCC has license rights under Section 6.1.  TDCC or the Affiliate shall have thirty (30)
days to withdraw such reexamination or opposition after notice from Symyx to
avoid termination of the license.  6.3Disclaimer.  SYMYX MAKES NO OTHER REPRESENTATIONS AND
EXTENDS NO WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED,
WITH RESPECT TO THE SYMYX COMBINATORIAL PATENT RIGHTS, OR SYMYX COMBINATORIAL
KNOW HOW, INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF MERCHANTABILITY, FITNESS
FOR A PARTICULAR PURPOSE, VALIDITY OF ANY SYMYX COMBINATORIAL PATENT RIGHTS OR
NONINFRINGEMENT OF THE INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES.  6.4Right
to Extend Licenses to Affiliates. 
TDCC shall have the right to extend the licenses and rights set forth in
this Article 6 to any of its Affiliates (but such Affiliates shall have no
right to grant any further extensions), provided that TDCC shall not then be in
default with respect to any of its obligations to Symyx under this Article 6
or Section 8.5.  Any such extension
shall be in writing and shall be accepted in writing by such Affiliate.  A copy of such writing shall be provided to
Symyx upon request.  All of the
restrictions set forth in this Agreement with respect to the  Confidential  26


Combinatorial
Chemistry License shall apply to such Affiliate to the same extent as they
apply to TDCC and the operations of such Affiliate shall be deemed to be
subject to the same obligations as the operations of TDCC.  TDCC shall account therefore and be primarily
responsible for the performance by such Affiliate of all of its obligations
hereunder, if the Affiliate fails to comply. 
A license extended under this Section 6.4 shall terminate for a
given entity at the time such entity ceases to be an Affiliate if not expiring
or terminated sooner under the terms of this Agreement.  6.5After
Program Term.  TDCC may extend the
term of the license granted pursuant to Section 6.1 on an annual basis by
written notice to Symyx at least * prior to the expiration of the Program Term
and each anniversary thereof that the license remains in force.  If TDCC elects to extend the term of such
license, TDCC shall pay Symyx * for each year the license extension is in
place, for a license of the same scope as set forth in this Article 6.  In the event TDCC desires a license of
reduced scope, the parties shall negotiate in good faith the terms and
conditions of such reduced license.  6.6Workflows,
Instruments and Equipment Created Pursuant to License. The license provided
in this Article 6 (and related provisions) shall continue in effect after
the Program Term (and any extension pursuant to Section 6.5) or after an
earlier termination of Article 6, as applicable, solely with respect to
any specific workflow, instrument or equipment within the license in Section 6.1
that is built (or assembled) and validated during the Program Term (or an
extension thereof pursuant to Section 6.5 or as set forth in Section 6.7),
or prior to any earlier termination of Article 6, as applicable, for the
life of such workflow, instrument or equipment. 
For purposes of clarification, the prior sentence is applicable only
with respect to actual workflows, instruments or equipment built (or assembled)
and validated during the Program Term (or an extension thereof pursuant to Section 6.5
or as set forth in Section 6.7), ), or prior to any earlier termination of
Article 6, as applicable, and not to duplicates, copies or replacements
thereof (provided that during the Program Term, TDCC may request information
from Symyx as to the expected cost of a license under Symyx intellectual
property, if any, for TDCC to duplicate any particular workflow, instrument or
equipment, and Symyx shall provide such information and a binding offer on
reasonable terms upon request). A workflow, instrument or equipment shall be
validated when it is demonstrated to be capable of performing the experiments
for which it was designed in a repeatable manner with a demonstrated,
significant correlation to conventional (non-Combinatorial) experiments.  At the end of the Program Term, TDCC upon
request shall notify Symyx of the workflows, instruments and equipment subject
to this license (such information to be deemed Confidential Information and may
be subject to enhanced protection reasonably requested by TDCC).  6.7Work in Process.  In
the event TDCC undertakes the development of a workflow, instrument or
equipment at least * prior to the end of the Program Term, such workflow,
instrument or equipment is reasonably intended to be completed by the end of
the Program Term (or any extension pursuant to Section 6.5), and such
workflow, instrument or equipment is substantially complete by the end of the
Program Term, TDCC shall be licensed under this Article 6 to complete the
development of such workflow, instrument or equipment for an additional *.  If such workflow, instrument or equipment is
validated (as described in Section 6.6) by the end of such * period, such  Confidential  27


workflow,
instrument or equipment shall be within the license set forth in Section 6.6.
At the end of the Program Term, TDCC upon request shall notify Symyx of the
workflows, instruments and equipment subject to this Section 6.7 (such
information to be deemed Confidential Information and may be subject to enhanced
protection reasonably requested by TDCC).  6.8Results of Research.  TDCC and its Affiliates to whom rights are
extended pursuant to Section 6.4 shall have the right during the Program
Term and thereafter to sell or otherwise transfer
to Third Parties products resulting from conducting research pursuant to the
license provided in this Article 6 and to license technology resulting
from conducting research pursuant to the license provided in this Article 6
without additional consideration due Symyx, except for royalties otherwise due
if the underlying product was subject to royalty provisions under this
Agreement or the CRLA.  Notwithstanding
the above, TDCC shall not have the right to transfer Discovery Tool Systems or
components thereof to parties other than Affiliates.  6.9Third
Party Patents.  Upon request of TDCC
or Symyx during the Program Term, but not more frequently than four (4) times
per calendar year, representatives of each party shall meet to discuss Third
Party patents and pending patent applications that may impact the use of
Combinatorial Chemistry Technology.  The
purpose of the discussion is to share information concerning prior art, the
scope and interpretation of patent claims and methods of avoiding

obligated to share information that it deems may compromise attorney-client
privilege.  Article 7
DISCOVERY TOOLS  7.1General Principles.  It is the expectation of TDCC and Symyx
DTools that at TDCCs request and in accordance with a mutually agreed upon
schedule, Symyx DTools shall deliver to TDCC Discovery Tools Systems during the
Program Term.  TDCC commits to purchase an average of * in Tools Price of Symyx
Discovery Tools per year during the Program Term for a total of at least * of
Symyx Discovery Tools during the Program Term, including at least * in
aggregate Tools Price of Symyx Discovery Tools in * (including at least *on
or before *) and at least * in
aggregate Tools Price of Symyx Discovery Tools in *, provided Symyx DTools is
able to deliver within such time periods the Discovery Tools Systems as set
forth in Exhibit H. In the event TDCC purchases a greater amount of Symyx
Discovery Tools during the Program Term than described in the previous
sentence, the pricing provisions set forth in this Article 7 shall apply
to such additional purchases.  Attached
hereto as Exhibit H is the parties determination of the deliverables for the
first year and a tentative plan with respect to deliverables for one or more
subsequent years.  Subject to the terms of
this Agreement, TDCC will have flexibility to select the Discovery Tools it
wishes to acquire during the Program Term. 
TDCC will provide to Symyx annually during the Program Term a two-year
estimate of projected Discovery Tool purchases. TDCC and Symyx will consult and
take commercially reasonable actions to address each others interests in making
reasonable adjustments in scheduling and delivery of Discovery Tool Systems.
TDCC shall provide Symyx with at least * notice prior to the desired delivery of
a Discovery Tools system unless mutually agreed otherwise  Confidential  28


and Symyx will inform TDCC of estimated lead times required for
Discovery Tool Systems to assist TDCC in planning.  7.2Eligible Tools
Systems.  Symyx DTools shall transfer
and make available for delivery to TDCC pursuant to this Article 7 during
the Program Term the following categories of Discovery Tools Systems: *.  7.3Procedure.  TDCC shall notify Symyx DTools at such time
as it (or an Affiliate to which TDCC has extended rights pursuant to Section 7.15)
is interested in acquiring a Discovery Tools System hereunder.  At such time as the specifications for a
Discovery Tools System are finalized, Symyx DTools will provide to TDCC or such
Affiliate a mutually-acceptable detailed estimate of the Tools Cost Basis for
such Discovery Tools System (as agreed upon by the parties, a Detailed Cost
Estimate).  If the parties do not agree
on the estimate for the Tools Cost Basis, Symyx shall upon request make
available for review documentation reasonably in its possession concerning the
basis for such Tools Cost Basis.  If the
parties still do not agree on the estimate, the matter will be elevated by the
Tools Committee to the Advisory Committee and then to the Executive
Committee.  If TDCC or such Affiliate
elects to proceed with acquisition of such Discovery Tools System, TDCC or such
Affiliate and Symyx DTools will enter into a definitive agreement that
specifies the description and specifications of the Discovery Tools System, the
anticipated Tools Price for such system based on the Detailed Cost Estimate,
the provisions that will apply with respect to validation, delivery and payment
for such system, the training and documentation to be delivered in connection
with the Discovery Tools System, whether such Discovery Tools System will
include TDCC Supplied Components as described in Section 7.5, the warranty
coverage applicable to such Discovery Tools System and any other relevant terms
and conditions not otherwise specified herein. Symyx DTools shall use
commercially reasonable efforts to deliver each Discovery Tools System within *
following the effective date of the definitive agreement for such system,
unless otherwise agreed.  During fabrication
of a Discovery Tools System, Symyx DTools shall provide periodic (at least
quarterly) revised estimates of the anticipated Tools Cost Basis of such
system.  In the event that Symyx DTools
believes that the Tools Cost Basis of a Discovery Tools System is likely to
exceed the Detailed Cost Estimate provided pursuant to this Section 7.3 by
more than * (excluding increases based on change orders or agreed upon changes
in the design or components of the Discovery Tools System), Symyx DTools shall
provide prompt written notice thereof to TDCC, together with an estimate of the
anticipated amount of the cost overrun and an explanation of the reasons
therefore.  Symyx DTools shall cooperate
fully with TDCC to mitigate any such cost overrun.  In the event Symyx DTools notifies TDCC that
the actual Tools Cost Basis for a Discovery Tools System is likely to exceed *
of the Detailed Cost Estimate (excluding increases based on change orders or
agreed upon changes in the design or components of the Discovery Tools System),
or if the periodic revised estimates of the anticipated Tools Cost Basis of a
Discovery Tools System provided by Symyx DTools demonstrate that the actual
Tools Cost Basis for a Discovery Tools System is likely to exceed * of the
Detailed Cost Estimate provided to TDCC hereunder (excluding change orders or
agreed upon changes in the design or components of the Discovery Tools System),
TDCC may elect to terminate the relevant definitive agreement for such
Discovery Tools System by written notice to Symyx.  Upon such termination, TDCC will notify Symyx
it will either: (i) pay to Symyx DTools the  Confidential  29


Tools Price, based
on the Tools Costs Basis incurred through the date written notice of termination
is received by Symyx, and Symyx shall provide to TDCC all materials
constituting work in progress or completed paid for by TDCC in accordance
therewith, or (ii) authorize Symyx to continue work only to a defined point
where the materials constituting the work in progress shall then be delivered
to TDCC with payment then due as in (i) above. 
In the event any particular Discovery Tools System is completed and
delivered hereunder and the actual Tools Cost Basis for such Discovery Tools
System exceeds * of the Detailed Cost Estimate provided to TDCC hereunder
(excluding change orders or agreed upon changes in the design or components of
the Discovery Tools System), TDCC may elect by written notice to Symyx to
reduce its total commitment to purchase Discovery Tools System under this
Agreement (as set forth in Section 7.1) by *. In the event of change
orders or changes in the design or components of the Discovery Tools System
that TDCC or such Affiliate requests and that the parties mutually approve, the
parties will negotiate appropriate adjustments to the applicable cost estimate
and pricing of the Discovery Tools System based on such changes.  7.4Tools
Price.  TDCC shall pay Symyx DTools
for Discovery Tools Systems transferred during the Program Term the Tools Price
as follows:  (1) for Newly Developed
Discovery Tools Systems or modules of Discovery Tools Systems that are
designated Newly Developed Discovery Tools System, the Tools Price shall be *;
and (2) for all other Discovery Tools Systems (excluding modules that are
designated a Newly Developed Discovery Tools System), the Tools Price shall be
*.  In addition to the Tools Price, TDCC
also shall pay Symyx DTools the cost of any additional warranty beyond the Warranty
Period as provided for in the agreement for any particular Discovery Tools
System as set forth in Section 7.11. The Tools Price described in this Section 7.4
is exclusive of federal, state, and local excise, sales, use, value added/ad
volorem taxes, surtax and personal property taxes, fees export/import charges
and other governmental assessments and similar taxes.  TDCC shall be liable for and shall pay all
applicable taxes and duties (other than taxes imposed on or measured by net
income) appropriately invoiced by Symyx DTools, except to the extent TDCC
provides Symyx DTools with a properly executed tax exemption certificate prior
to delivery of an invoice setting forth any such taxes.  TDCC shall
not be liable for any federal, state, or local income tax, franchise tax, or
similar tax based upon Symyxs income. 
In addition to the Tools Price, TDCC shall bear all costs for
transportation, shipping, and insurance expenses in respect of shipment to a
delivery point designated by TDCC.  The
Tools Price shall be payable upon delivery and completion of validation of the
Discovery Tools System as set forth in the agreement for each Discovery Tools
System, unless otherwise mutually agreed by the parties, except that the
definitive agreement for each Discovery Tools System described in Section 7.3
will provide for some level of advance payments to fund the development and
construction of the Discovery Tools System. 
The total Tools Price paid by TDCC and its Affiliates for any and all
Discovery Tools System and Newly Developed Discovery Tools System shall be
included in determining whether TDCC has satisfied its commitments under Section 7.1.  7.5TDCC
Supplied Components.  The parties may
agree, on a case by case basis, to include TDCC Supplied Components within a
Discovery Tools System, which agreement will not unreasonably be withheld. For
example, commercial analytical equipment may be TDCC Supplied Components by
mutual agreement.  TDCC Supplied
Components should not necessitate additional  Confidential  30


software,
engineering or chemistry work on the part of Symyx. It is understood, however,
that Symyx routinely incorporates Third Party components in its Discovery Tools
Systems, and that the integration, software control, validation, warranty and
support of these items within the context of an integrated workflow constitutes
part of the value of a Discovery Tools System. 
Accordingly, the parties expect that Symyx will continue to incorporate
Third Party components in its Discovery Tools Systems consistent with its
current business practices and that such Third Party components will be
included within the Tools Cost Basis, absent an agreement that they shall be
TDCC Supplied Components.  7.6Tools
License. Subject to the terms and conditions of this Agreement, Symyx
hereby grants to TDCC the following licenses in connection with any Discovery
Tools System delivered hereunder, in each case for the life of such Discovery
Tools System (without regard for any expiration or termination of this

TDCC agrees to establish and maintain records of Named Users and changes to
Named Users.  7.8TDCC
Improvements.  TDCC may at its option
notify Symyx of any TDCC Improvements during the term of this Agreement;
provided that TDCC shall promptly notify Symyx in the event any patent
publishes or is issued with respect to any TDCC Improvements. TDCC is not
required to license or offer TDCC Improvements for license to Symyx or anyone
else, and any license of TDCC Improvements to an Affiliate of TDCC shall not be
deemed a license that triggers the provisions of this Section.  During the Program Term and for * thereafter,
TDCC hereby grants Symyx *.  Nothing
contained herein shall be deemed to provide a license to TDCC to Symyxs
intellectual property rights with respect to any license agreement TDCC may
enter into with a Third Party pursuant to the provisions of this Section.  7.9Consumables.  TDCC may purchase consumables for the
operation of Discovery Tools Systems delivered hereunder or have consumables
made for such use by TDCC or its Affiliates, without compensation to Symyx,
provided that Symyx patents are not infringed by article claims directed
to such consumables.   TDCC may purchase
or otherwise acquire consumables for the operation of the Discovery Tools
Systems delivered hereunder from Symyx Dtools at Symyx Dtools then-current
fees.  Symyx DTools agrees to negotiate
in good faith with respect to quantity discounts for Consumables purchases
consistent with its practices for similar transactions.  Symyx Dtools will make good faith and
commercially reasonable efforts to satisfy TDCCs requirements for such
consumables as necessary for the operation of the Discovery Tools Systems,
provided TDCC has given Symyx Dtools adequate lead time for the delivery of
such consumables.  Prior to the beginning
of each calendar quarter, TDCC shall provide to Symyx Dtools a forecast of TDCCs
anticipated requirements for consumables for the next * and Symyx shall confirm
the price at which these are available to TDCC. 
Each forecast shall be non-binding on TDCC; provided, however, that TDCC
shall use commercially reasonable efforts to make such forecasts as accurate as
possible. TDCC may initiate purchases of such consumables by fax or by e-mail
(at an address to be designated by Symyx Dtools) or by submitting written
purchase orders to Symyx Dtools. In the event Symyx Dtools is unwilling or
unable, either itself or through a designated licensee or third party, to
satisfy TDCCs requirements for consumables, and such consumables are alone, or
in combination with a Discovery Tools System or component thereof, covered by a
claim of an issued patent owned or controlled by Symyx, which claim has not
expired or been held to be invalid or unenforceable by a court of competent
jurisdiction, Symyx agrees to grant, and hereby grants, to TDCC a nonexclusive,
royalty bearing, limited license to make or have made such consumables solely
for TDCCs Internal Research and Development Activities only in connection with
the operation of the Discovery Tools System. 
In the event TDCC elects to have such consumables made for it by a Third
Party under such  Confidential  32


license, the
contract with the Third Party to supply consumables will specify that the
license is only to make and sell these licensed consumables for the use and
benefit of TDCC and TDCC Affiliates.  The
parties agree to document the terms of such a license in good faith, with such royalty not exceeding *.  7.10Legend.  All copies of the Discovery Tools Systems
delivered hereunder and any accompanying software and related documentation

the event any claim, action, suit or proceeding is brought in * against TDCC
claiming that a Discovery Tools System or any component thereof infringes a
claim of a Third Partys * patent or * copyright or misappropriates a  Confidential  35


trade secret
right, Symyx shall defend the same at its expense and pay any costs, damages
and attorney fees finally awarded or negotiated as a result of settlement or
judgment against TDCC, provided that TDCC gives Symyx prompt written notice
within * of such claim against it and cooperates reasonably with Symyx in
providing all authority, information and reasonable assistance to enable Symyx
at its option to settle or defend such claim. 
Any settlement that * shall require prior written consent from TDCC,
which shall not be unreasonably withheld. Symyx shall have no liability for any

Ventures as set forth in Exhibit J, and (b) a share of any payments from Sublicensees
as set forth in Exhibit J.  8.11Payments
in Lieu of Royalties.  Royalties due
on Net Sales of Products or classes of Products may be burdensome to calculate
and report.  TDCC and Symyx Tech in such
cases will seek to negotiate an alternative basis for calculation of
consideration payable in lieu of running royalties on such classes of Products,
which both parties deem will result in a payment to Symyx Tech of an amount
commensurate with the royalties otherwise payable under Section 8.10.  Confidential  38


8.12Third
Party Royalties.  Symyx shall not be
responsible for payments due to Third Parties for the manufacture, sale, or use
of Products by TDCC or its Affiliates or Sublicensees, unless Symyx has entered
into a specific written contract to pay same.  8.13Convenience
of the Parties.  The parties
acknowledge that Symyx may not own or control patent applications or patents
covering the manufacture, sale or use of a particular Product; however, that
parties agree that substantial value is expected to be contributed by Symyx in
accelerated identification, time to market, enhanced probability of success,
and the potential for multiple leads and, for the convenience of the parties,
TDCC agrees to pay royalties as specified herein during the applicable royalty
period, regardless of whether a Product is covered by a patent application or
patent owned or controlled by Symyx.  Article 9

business for other commercial transactions on the last business day of the
calendar year quarter to which such payment pertains.  If, due to restrictions or prohibitions
imposed by national or international authority, payments cannot be made as
aforesaid, the parties shall consult with a view to finding a prompt and
acceptable solution.  If  Confidential  39


such royalties due
Symyx Tech in any country cannot be remitted to Symyx Tech within * after the
end of the calendar year quarter during which they are earned, then TDCC or its
Affiliate shall upon request of Symyx Tech deposit the full amount of such
unpaid royalties in a bank account in such country in the name of Symyx Tech,
provided that if, due to restrictions or prohibitions imposed by national or
international authority, TDCC has not received payment for the Products
generating the royalty payment obligation, the parties shall consult with a
view to finding a timely and acceptable solution.  9.4Records;

principal place of business of such party, as the case may be, for at least *
following the end of the calendar year quarter to which they pertain.  Such records will be open for inspection
during such * period by a public accounting firm to whom the party having the
books and records has no reasonable objection, solely for the purpose of verifying
royalty reports provided pursuant to Section 9.1.  Such inspections may be made no more than
once each calendar year, at reasonable times and on reasonable notice.  Inspections conducted under this Section 9.4
shall be at the expense of party initiating the audit, unless a variation or
error producing an increase in the payment due exceeding * of the amount stated
for any period covered by the inspection is established in the course of any
such inspection, whereupon all reasonable costs relating to the inspection for
such period and any unpaid amounts that are discovered will be paid promptly by
the party audited together with interest thereon from the date such payments
were due at the lesser of (i) * or (ii) the maximum rate permitted by
law. The public accounting firm employees shall sign a reasonable
confidentiality agreement as a condition precedent to their inspection, and
shall report to the party initiating the audit only that information which
would be contained in a properly prepared royalty report. The party initiating
the audit shall hold in strict confidence all information received concerning
royalty payments and reports, and all information learned in the course of any
audit or inspection, except to the extent necessary to reveal such information
in order to enforce its rights under this Agreement or if disclosure is
required by law.  9.5Tax
Matters.  All royalty amounts and
other payments required to be paid to a party pursuant to this Agreement may be
paid with deduction for withholding for or on account of any taxes (other than
taxes imposed on or measured by net income) or similar governmental charge
imposed by applicable law (Withholding Taxes).  Any Withholding Taxes will be paid to the
proper tax authorities and receipts for such payment or other proof of payment
will be made available by the paying party to the other party.  The parties will exercise diligent efforts to
ensure that any withholding taxes imposed are reduced as far as possible under
provisions of any treaties applicable.  Article 10

10.6Cooperation
in Patent Filing.  During the Program
Term and for * thereafter, TDCC and Symyx shall use reasonable efforts to keep
each other informed as to the status of patent matters described in this Article 10
(other than Section 10.4), including without limitation, by providing the
other the opportunity to review and comment on patent application drafts
providing the basis for Program Patents claiming inventions made in the course
of the Research Program a reasonable time in advance of applicable filing
dates, and providing the other party with copies of any substantive documents
that such party receives from applicable patent offices regarding applications
for any Program Patent, and/or applications claiming any Joint Inventions,
promptly after receipt, including notice of all official actions, interferences,
reissues, re-examinations, oppositions, potential litigation, or requests for
patent term extensions.  TDCC and Symyx
shall each reasonably cooperate with and assist the other at its own expense in
connection with such activities, at the other partys request.  The relevant Research Committee, either
directly or through a patent committee designated by the Research Committee,
will (i) facilitate communication between the parties regarding patents
and patent applications arising from inventions made in the course of the
Research Program, and (ii) discuss and provide advice on patent strategy
related to such patent applications.  It
is understood and agreed that provisional patent applications may be filed by a

review and comment from the other party prior to filing such provisional patent
applications.  10.7Enforcement.  10.7.1Notice.  Each party shall promptly notify the other
party in writing if it becomes aware of any actual or threatened commercially
material infringement of the Program Patents by a Third Party.  10.7.2Inside the
Fields.  TDCC shall have the initial
right, but not the obligation, to take appropriate legal action to enforce any
Program Patents against any infringement within * by any Third Party, at its
sole cost and expense.  If, within *
following receipt of notice from Symyx of any such infringement of a
jointly-owned, issued patent, TDCC does not take such action to halt such
infringement or notify Symyx of action it proposes to take to abate patent
infringement in a commercially reasonable period, Symyx shall, in its sole
discretion, have the right, but not the obligation to take such action at its
sole expense.  10.7.3Other
Infringement.  In the event of an
actual or threatened infringement by a Third Party of a Program Patent that is
solely owned by TDCC, TDCC shall have the sole right, but not the obligation,
to take appropriate legal action to enforce such Program Patent against
infringements by Third Parties, as TDCC determines and at its expense. Except
as otherwise provided in Section 10.7.2, in the event of an actual or
threatened infringement by a Third Party of a Program Patent that is solely
owned by Symyx, or jointly by TDCC and Symyx, Symyx shall have the sole right,
but not the obligation, to take appropriate legal action to enforce such
Program Patent against infringement by Third Parties, as Symyx determines in
its  Confidential  43


discretion and at its
expense.  It is understood that Symyx may
authorize one or more Third Parties to enforce patents against infringements
outside of the Fields.  10.7.4Cooperation;
Costs and Recoveries; Settlements. 
Each party agrees to use commercially reasonable efforts to render such
assistance in the enforcement activities described in Sections 10.7.2 and
10.7.3 as the enforcing party may reasonably request.  Costs of maintaining any such action and
damages recovered therefrom shall be paid by and belong to the party bringing
the action; provided, however, that any recovery by TDCC under Section 10.7.2
in excess of * shall be divided * to TDCC and * to Symyx.  If TDCC consents to a sublicense to any Third
Party, which consent it shall not be required to give, who, but for the
sublicense, would be infringing a claim of an issued patent in the Program
Technology, TDCC shall be entitled to receive all running royalties payable by such
Third Party but such revenue received in excess * shall be included as a part
of revenues received from Sublicensees as set forth in Section J2.1(iv) or
J3.1  of Exhibit J.  Neither Symyx nor TDCC shall settle without
the consent of the other party a dispute with a Third Party regarding
infringement of a Program Patent except to the extent that such rights could
have been granted as a permitted license or sublicense without the consent of
the other party.  10.8Third
Party Claims of Infringement.  If the
manufacture, use or sale of any Product pursuant to this Agreement because of
the practice of the Program Technology results in any claim, suit or proceeding
alleging patent infringement against Symyx or TDCC (or its Affiliates or
Sublicensees), such party shall promptly notify the other party hereto in
writing setting forth the facts of such claims in reasonable detail. Each party
agrees to use commercially reasonable efforts to render assistance to the other
party in defending such claims of infringement as the defendant may reasonably
request.  The defendant shall have the *
right and obligation to defend and control the defense of any such claim, suit
or proceeding, at its own expense, using counsel of its own choice; provided,
however, it shall not enter into any settlement which admits or concedes that
any Program Patent is invalid or unenforceable, without the prior written
consent of the other party, which shall not be unreasonably withheld.  The defendant shall keep the other party
hereto reasonably informed of all material developments in connection with any
such claim, suit or proceeding.  Article 11
COMMERCIALIZATION  11.1Due
Diligence.  TDCC shall use
commercially reasonable efforts to develop and commercialize Agreement
Compounds and Products which in TDCCs sound business judgment can be
profitably implemented.  It is understood
and agreed that such commercially reasonable efforts shall mean efforts
generally equivalent to the efforts TDCC uses with regard to its other similar
products (lower case) of comparable value, risk
and patent protection to develop and commercialize Products.  Specific diligence parameters will include
TDCC utilizing its knowledge of chemical and polymer markets to identify
suitable concepts for Products and market opportunities.  Confidential  44


11.2Acquisition
of Rights by Symyx Tech.  In the
event that TDCC determines it will not commercialize on its own or by license
to Third Parties or Affiliates of TDCC one or more discrete, specified chemical
entities that were identified as Lead Compounds to manufacture one or more
specified Products with respect to one or more Fields, TDCC shall notify Symyx
Tech in writing.   Symyx Tech shall for a
period of * from the receipt of such notification have the option, on written
notice to TDCC, to obtain an exclusive, worldwide right under TDCCs interest
in Program Technology and at TDCCs discretion, improvements or modifications
made by TDCC to such Program Technology for such Lead Compounds to be used to
manufacture, use and sell the specified Products, on * terms *.  Symyx Techs option rights under this Section 11.2
will not be applicable to the extent that, and only for so long as, TDCCs
decision not to commercialize a particular Lead Compound is a result of its
active pursuit of the commercialization of another Agreement Compound under
this Agreement or the CRLA with respect to either the same Product or a Product
that would compete commercially with such Product.  11.3Reports.  During the term of this Agreement, TDCC
shall, at the written request of Symyx Tech, provide Symyx Tech with written *
reports within * of * providing a summary of the status of the research and
development activities conducted with respect to Products and Agreement
Compounds.  In addition, * times during
the term that royalties may be payable, Symyx Tech may request special reports
that provide a summary of the status of the research and development activities
conducted with respect to Products and Agreement Compounds.  TDCC will provide these special reports
within * of notification.  The reports as
described in this Section 11.3 shall contain sufficient information to
allow Symyx Tech to monitor TDCCs compliance with this Agreement. In addition,
the parties shall at Symyxs request engage in quarterly confidential
consultations with respect to the status of TDCCs efforts to develop and
commercialize Agreement Compounds and Products during the Program Term and for
* thereafter, and at Symyxs request, * during the remaining period that
royalty payments may be due to Symyx Tech. 
Any information to be provided to Symyx Tech may be subject to enhanced
secrecy obligations to be negotiated. All reports and information provided
under this Section 11.3 shall be deemed Confidential Information of TDCC.  Article 12
CONFIDENTIALITY  12.1Confidentiality.  Except as otherwise expressly provided
herein, the parties agree that, until the later of: (i) * from the Effective
Date of the Agreement, or (ii* from the end of the Program Term, the receiving
party shall not, except as expressly provided in this Article 12, disclose
to any Third Party or use for any purpose, any Confidential Information
furnished to it by the disclosing party pursuant to this Agreement, except in
each case to the extent that it can be established by the receiving party by
competent proof that such information:  (a)was
already known to the receiving party, other than under an obligation of
confidentiality, at the time of disclosure;  (b)was
generally available to the public or otherwise part of the public domain at the
time of its disclosure to the receiving party;  Confidential  45


(c)became
generally available to the public or otherwise part of the public domain after
it disclosure and other than through any act or omission of the receiving party
in breach of this agreement;  (d)was
independently developed by the receiving party without use of, or reference to,
the other partys confidential information, as demonstrated by documented
evidence; or  (e)was
disclosed to the receiving party, other than under an obligation of
confidentiality, by a Third Party authorized and entitled to disclose such
information to others.  ConfidentialInformation shall not be considered within
the above exceptions merely because the Confidential Information is embraced by more general
information within the exceptions.  Any
combination of features of Confidential Information shall not be considered within the above exceptions merely
because individual features, as opposed to the combination itself and its
principles of operation, are within the exception.  Program Know-How to the extent that it is
exclusively licensed to TDCC pursuant to Section 4.1 shall be treated by
Symyx as if it were Confidential Information disclosed to it by TDCC for
purposes of Sections 12.1, 12.2, 12.4 and 12.5.  12.2Permitted
Use and Disclosures.  Each party
hereto may (i) use Confidential Information disclosed to it by the other
party in conducting the Research Program or otherwise performing their
obligations hereunder, and (ii) use or disclose Confidential Information
disclosed to it by the other party to the extent such use and disclosure is
reasonably necessary in (A) exercising the rights and licenses granted
hereunder, (B) prosecuting or defending litigation, (C) complying

orders or submitting mandatory information to tax or other governmental authorities,
(D) filing and prosecuting patent applications, subject to consultation with
the disclosing party as to the content of such patent applications prior to
filing other than as set forth in Section 10.6, or (E) making a
permitted sublicense or otherwise exercising license rights expressly granted
pursuant to this Agreement. TDCC and Symyx shall not (and agree that their
Affiliates shall not) disclose Confidential Information received from the other
party under this Agreement as permitted by 12.2(ii)(A) or (E), except pursuant
to an agreement of confidentiality with terms reasonably equivalent to those
applicable to the party to this Agreement that received the information from
the other. If a party to this Agreement is required to make any disclosure
pursuant to 12.2(ii)(B), (C) or (D) of Confidential Information received, it
will give reasonable advance notice to the other party to this Agreement and
will use reasonable efforts to secure confidential treatment of such
information (whether through protective order or otherwise), except to the
extent inappropriate in the case of patent applications.  12.3Nondisclosure
of Terms.  Each of the parties hereto
agrees not to disclose the terms of this Agreement to any Third Party without
the prior written consent of the other party hereto, which consent shall not be
unreasonably withheld, except to such partys attorneys, advisors, investors
and others on a need to know basis under circumstances that reasonably ensure
the confidentiality thereof either: (i) in connection with exercising the
rights and licenses granted hereunder, or prosecuting or  Confidential  46


defending
litigation, (ii) in connection with negotiation of a sublicense, manufacture or
sale of a Product or an Agreement Compound, or (iii) to the extent required by
law.  Notwithstanding the foregoing, the
parties shall agree upon a press release to announce the execution of this
Agreement or developments under this Agreement, and Symyx and TDCC may each
thereafter disclose to Third Parties the information contained in such press
release without the need for further approval by the other.  12.4Publication
of Results.  Any manuscript or other
public disclosure by Symyx or TDCC describing the scientific results of the
Research Program to be published within the Program Term, or within * after the
end of the Program Term, shall be provided to the other party for review at
least * prior to its submission, except that patent applications which may be
published shall be subject only to the review described in Section 10.6.  Further, to avoid the loss of patent rights
as a result of premature public disclosure of patentable information, the
reviewing party may, within * of receiving such a proposed disclosure, notify
the publishing party in writing that the reviewing party desires to file a
patent application on any invention disclosed in such scientific results, in
which case the publishing party shall withhold publication or disclosure of
such scientific results until the earlier of (i) the time the patent
application is filed thereon, (ii) the time the parties both determine,
after consultation, that no patentable invention exists, or (iii) * after
the publishing party received notice of the reviewing partys desire to file
such patent application.  Further, if
such scientific results contain Confidential Information of the reviewing party
that is subject to the use and nondisclosure restrictions under this Article 12,
the publishing party agrees to remove such Confidential Information from the
proposed publication or disclosure.  12.5Procedure.  Upon request of the party disclosing the
Confidential Information, providing Software or having an exclusive license of
Program Know-How, the other party will provide reasonable information
concerning practices and procedures it has established to avoid breach of
obligations in this Article 12 or under the exclusive licenses granted by
this Agreement.  Article 13

(collectively, Liabilities) arising, directly or indirectly out of or in
connection with Third Party (including TDCC employees and TDCC independent
contractors) claims, suits, actions, demands or judgments, including without
limitation, personal injury, product liability, patent infringement and trade
secret misappropriation  Confidential  48


matters, suits,
actions or demands relating to *, except, in each case, to the extent such
Liabilities result from *. The obligation to indemnify as set forth in this Section 14.1:
(a) shall apply regardless of any insurance coverage of the indemnifying party
and (b) shall apply when the Third Party asserting the claim, suit, action,
demand or judgment under this Section 14.1 is a party providing insurance
to the indemnifying party.  14.2Symyx.  Symyx agrees to indemnify, defend and hold
harmless TDCC, its Affiliates and Sublicensees and their respective directors,
officers, employees, agents and their respective heirs and assigns (the TDCC
Indemnitees) from and against any losses, costs, claims, damages, liabilities
or expense (including reasonable attorneys and professional fees and other
expenses of litigation) (collectively, Liabilities) arising, directly or
indirectly out of or in connection with Third Party (including Symyx employees
and Symyx independent contractors) claims, suits, actions, demands or
judgments, including without limitation, personal injury, product liability,
patent infringement and trade secret misappropriation matters, suits, actions,
or demands relating to*; and except, in each case, to the extent such

obligations of Symyx DTools under this Agreement and owns or controls the
assets sufficient to fully perform these obligations to the same extent as
Symyx DTools. Termination shall have the effects set forth in Section 15.6.  In addition, in such event, TDCCs
obligations pursuant to Sections 11.2 and 11.3 shall terminate.  15.5Performance.  In the event Symyx has failed to achieve more
than * of the Annual Program Goals, as established pursuant to Section 3.5,
for * of the Program Term for one or more of either the Research Program,
Software Deployment Plan or the Discovery Tools Systems, as evidenced by the
written documentation generated during the normal course of this Agreement,
TDCC shall notify Symyx no later than *, provided that TDCCs actions up to
that point in time are not a substantial cause of Symyxs failure to achieve
more than * of the Annual Program Goals for * of the Research Program.  TDCC and Symyx shall both use reasonable
commercial efforts to determine how to remedy the failure for * from such
notice, and then Symyx shall have the option of adding personnel and other
resources, at its own expense, to cure such failure within * thereafter.  If Symyx does not cure within this additional
