ARTICLE 7

DISCOVERY TOOLS

7.01 General Principles. It is the expectation of ExxonMobil and Symyx DTools that at ExxonMobil’s request and in accordance with a mutually agreed upon schedule, Symyx DTools shall deliver at least * Discovery Tools Systems (excluding Incremental Add-Ons to existing Discovery Tools Systems, but including Discovery Tools Systems being developed under the CRDLA (which will be subject to the pricing provisions of this Article)) to ExxonMobil and its Affiliates prior to * following the end of the Research Program Term (the “Tool Delivery Period”). It is the expectation of ExxonMobil and Symyx DTools that the aggregate Tools Cost for such at least * Discovery Tools Systems will be approximately *. Symyx DTools shall use commercially reasonable efforts to provide additional Discovery Tools Systems during the Tool Delivery Period requested by ExxonMobil pursuant to the terms of this Agreement.

7.02 Procedure. ExxonMobil shall notify Symyx DTools at such time as it (or an Affiliate to which ExxonMobil has extended rights pursuant to Section 7.14) 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 ExxonMobil or such Affiliate a mutually-acceptable detailed estimate, consistent with Exhibit V, of the Tools Cost for such Discovery Tools System. If ExxonMobil or such Affiliate elects to proceed with acquisition of such Discovery Tools System, ExxonMobil or such Affiliate and Symyx DTools will enter into a definitive agreement that specifies the description of the Discovery Tools System, the anticipated Tools Price for such system based on such detailed cost estimate, the provisions that will apply with respect to acceptance, delivery and payment for such system, the exclusivity, if any, applicable to such system (as set forth in Section 7.05), whether or not such Discovery Tools System is considered to be an Incremental Add-On hereunder, a full “System” or some fraction thereof, and any other relevant terms and conditions. Symyx DTools shall use commercially

* Confidential treatment requested

reasonable efforts to deliver each Discovery Tools System within * months following the effective date of the definitive agreement for such system.

7.02.1 Revised Cost Estimates and Notification of Cost Overruns. During fabrication of a Discovery Tools System for ExxonMobil or an ExxonMobil Affiliate, Symyx DTools shall provide to ExxonMobil or such Affiliate periodic (at least quarterly) revised estimates of the anticipated Tools Cost of such system. In the event that Symyx DTools believes that the Tools Cost of a Discovery Tools System is likely to exceed the original detailed cost estimate provided to ExxonMobil or such Affiliate pursuant to Section 7.02, Symyx DTools shall provide prompt written notice thereof to ExxonMobil or such Affiliate, together with an estimate of the anticipated amount of the cost overrun and an explanation of the reasons therefor. Symyx DTools shall cooperate fully with ExxonMobil or such Affiliate and shall make all changes reasonably requested by ExxonMobil or such Affiliate to mitigate any such cost overrun. In the event of change orders, or changes in the design or components of the Discovery Tools System that ExxonMobil 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.

7.02.2 Responsibility for Cost Overruns. ExxonMobil or its Affiliate shall pay Symyx DTools, pursuant to Section 7.03, for a particular Discovery Tools System, provided that the actual Tools Cost for such system does not exceed * of the original detailed cost estimate provided to ExxonMobil or such Affiliate pursuant to Section 7.02. If the actual Tools Cost for such system exceeds * of the detailed cost estimate, then the excess (i.e., the amount by which the actual Tools Cost exceeds * of the original detailed cost estimate) shall not be subject to the relevant price multiplier set forth in Section 7.03, and ExxonMobil or such Affiliate shall reimburse Symyx DTools only for * of such excess. The provisions in this Section 7.02.2 are dependent on the compliance of the Discovery Tools System with the final specifications as described in Section 7.02.

* Confidential treatment requested

within the royalty-bearing project scope of the Royalty-Bearing Project from which such Product originated, as approved in writing by the Advisory Committee. Such license royalties shall be paid at royalty payment rates determined in accordance with Exhibit L (for all Royalty-Bearing Projects except the * Royalty Projects) or Exhibit O (for * Royalty Projects). For all Royalty-Bearing Projects, ExxonMobil shall also pay Symyx Tech a portion of any royalty payments received by ExxonMobil or its Affiliates from Licensees, as determined in accordance with Exhibits L or O, whichever is applicable. In the event that the license royalty rate for Net Sales or Use of a Product makes it economically impracticable to commence or continue commercial sale or use of the Product, ExxonMobil and Symyx Tech will discuss possible alternative mechanisms to distribute the value created under this Agreement without obligation to reach agreement. Nothing in this Agreement shall be interpreted or construed as obligating ExxonMobil or its Affiliates to commence or continue commercial sale or use of any Product.

ExxonMobil has internal procedures and mechanisms to obtain payments for use of Program Technology by its * Affiliates and will apply such procedures and mechanisms in implementing this Agreement.

At the time Symyx selects the * Royalty Project, Symyx may also select an “Alternate * Royalty Project,” and at the time Symyx selects the * Royalty Project, Symyx may also select an “Alternate * Royalty Project.” If ExxonMobil or an Affiliate to which rights hereunder have been extended has not commercialized any Products originating from the * Royalty Project at any time within * years after Symyx’ selection thereof, then Symyx shall have the right, but not the obligation, to substitute the Alternate * Royalty Project for the * Royalty Project. Similarly, if ExxonMobil or an Affiliate to which rights hereunder have been extended has not commercialized any Products originating from the * Royalty Project at any time within * years after Symyx’ selection thereof, then Symyx shall have the right, but not the obligation, to substitute the Alternate * Royalty Project for the * Royalty Project. In the event of any such substitution, no license royalties shall be due for activities occurring prior to the date of the substitution.

8.08 *. If ExxonMobil exercises one of the options set forth in Section H8(b) of Exhibit H, it shall make the payments to Symyx as set forth therein.

8.09 Third Party Royalties. Symyx shall not be responsible for payments due to Third Parties for the manufacture, sale, or use of Products by ExxonMobil or its Affiliates or Licensees, provided that such payments shall be taken into account in determining * pursuant to Exhibit L.

PROCEDURE FOR LEAD MATERIAL CONFIRMATION

F1. At such time as Symyx has identified a Material or family of Materials that it believes may meet the established criteria for a Lead Material in a particular ExxonMobil Exclusive Field it shall provide the data and results supporting such conclusion to the Research Committee. Examples of target criteria for Lead Materials are set forth in the Lead Material Criteria Section of the Research Plan.

F2. (a) Except as provided in Section F2(b), following the identification of any potential Lead Material, at ExxonMobil’s request, Symyx shall prepare and deliver to ExxonMobil or its Designee reasonable gram quantities of Lead Material(s), which ExxonMobil shall use in confirming whether such potential Lead Material meets the applicable lead criteria. Further, Symyx will communicate to ExxonMobil in writing the materials and conditions used to synthesize the potential Lead Materials. ExxonMobil shall use commercially reasonable efforts to confirm whether such potential Lead Material meets the applicable lead criteria within * of delivery of the potential Lead Material by Symyx, or such other reasonable period of time as the parties may agree at the time of the transfer. In certain circumstances, confirmation may be required in a pilot plant which may result in confirmation longer than *. Symyx will use commercially reasonable efforts to provide quantities in such amounts as the Research Committee may determine is reasonably required by ExxonMobil for testing, and will notify ExxonMobil if it is not commercially reasonable to provide such quantities to ExxonMobil, in which case the parties agree to meet and discuss how to proceed with respect to such Lead Material.

(b) Symyx shall advise ExxonMobil if it is not capable of providing reasonable gram quantities of a particular Lead Material to ExxonMobil for testing. In such event, ExxonMobil will have sole responsibility for preparing larger quantities of the potential Lead Material for testing to confirm whether such potential Lead Material meets the applicable lead criteria. Any additional knowledge or technology developed during such scale-up of the potential Lead Material shall be ExxonMobil Confidential Information and is specifically not considered Program Technology. ExxonMobil shall notify Symyx when sufficient Material has been prepared by ExxonMobil for testing. If preparation of larger quantities is reasonably anticipated to take longer than *, ExxonMobil will notify Symyx and the parties shall meet and discuss how to proceed. Within * of preparation by ExxonMobil of sufficient Material for testing, or such other period of time as the parties may agree at the time of notification of preparation of test quantities, ExxonMobil shall use commercially reasonable efforts to confirm whether such potential Lead Material meets the applicable lead criteria.

F3. The Research Committee shall review the results provided by ExxonMobil with respect to a potential Lead Material, and if the Research Committee determines that such results

* Confidential treatment requested

F-1

indicate that the applicable lead criteria have been satisfied, then such Material shall be deemed to be confirmed as a Lead Material for all purposes of this Agreement.

F4. In the event that the Research Committee requests further information or the conduct of further studies to confirm whether a potential Lead Material meets the applicable lead criteria, Symyx and ExxonMobil shall use commercially reasonable efforts to prepare any such information and conduct such studies.
