(b) Sellable Assets.

(i) The Seller agrees [ * ] provided that the Seller [ * ] sell or otherwise transfer the Sellable Assets or any portion thereof to any Person (other than Exelixis) for any use by such Person and to receive consideration in exchange for such sale or transfer, including cash, equity or other ownership interest in such Person [ * ] (the closing of such sale of the Sellable Assets, the “Sellable Assets Sale”, and such purchaser or transferee of the Sellable Assets, the “Sellable Assets Purchaser”), provided further that EPS [ * ].

(ii) EPS agrees that:

(1) prior to the Sellable Assets Sale, [ * ] any potential Sellable Assets Purchaser regarding the Sellable Assets;

(2) EPS shall not, and it will cause its Affiliates not to, directly or indirectly, [ * ] in connection with the Sellable Assets Sale;

(3)(A) EPS shall [ * ] transfer of the Sellable Assets and the provision of technical assistance to the Sellable Assets Purchaser, which may include the packaging, transferring and tracking of seeds, the transfer of data and database(s), and the transfer of licenses and permits [ * ]; (B) EPS shall [ * ]; and (C) [ * ] transfer of the Sellable Assets and the provision of technical assistance to the Sellable Assets Purchaser;

(c) Cell Factory Assets.

(i) Subject to the Purchaser’s rights as described in this Section 2.1(c)(i) and in Section 2.1(c)(ii) below, the Seller expressly reserves all rights to use and exploit the Cell Factory Assets for all purposes, including entering into collaboration with any Third Party to further develop the Cell Factory Assets with such Third Party, or selling or otherwise transferring the Cell Factory Assets to any Third Party. In particular and without limiting the foregoing, unless and until the Parties enter into a Cell Factory Purchase Agreement, the Seller shall have the right to: (1) fund, by itself or with or through their Affiliates or Third Parties, and continue to operate the Cell Factory Assets [ * ]; and (2) use the Cell Factory Assets to initiate

and conduct new research and collaborations, and to continue existing research and collaborations, at the Seller’s sole discretion; provided that the Seller [ * ].

The “Notice Period” shall mean the period that commences on the Effective Date and ends [ * ] thereafter, unless the Purchaser notifies the Seller within [ * ] after the Effective Date that the Purchaser and/or its Affiliates [ * ], in which case the period shall end [ * ] after the Effective Date.

SECTION 3. ASSUMED LIABILITIES AND EXCLUDED LIABILITIES.

3.1 Assumed Liabilities. The Purchaser shall assume all of the obligations and liabilities of any kind, character or description whatsoever, whether direct or indirect, known or unknown, absolute or contingent, matured or unmatured, that are (a) exclusively associated with the Purchased Assets or (b) associated with, but not exclusively, the Purchased Assets, to the extent such obligations and liabilities are associated with the Purchased Assets, in each case to the extent such obligations and liabilities arise after the Effective Date (collectively, the “Assumed Liabilities”). For clarity, Assumed Liabilities shall expressly include all obligations and liabilities associated with the Purchased Assigned Agreements arising after the Effective Date, and the Purchaser hereby agrees to be bound by the terms and conditions of the Purchased Assigned Agreements. The fact that a contract has been entered into by the Seller at or prior to

the Effective Date shall not determine whether a particular liability or obligation under such contract arose at or prior to the Effective Date. The Purchaser shall assume such Assumed Liabilities by executing and delivering to the Seller the Assignment and Assumption Agreement pursuant to Section 1.2(b)(iii).

3.2 Excluded Liabilities. Except for the Assumed Liabilities, the Purchaser shall not assume or be obligated to pay, perform or otherwise discharge, and the Seller shall retain, pay, perform, remain responsible for and otherwise discharge, any and all obligations and liabilities of the Seller of any kind, character or description whatsoever, whether direct or indirect, known or unknown, absolute or contingent, matured or unmatured, and currently existing or hereinafter arising (collectively, the “Excluded Liabilities”). Without limiting the foregoing, the Purchaser expressly does not assume and the following shall be considered Excluded Liabilities:

(a) any obligations and liabilities related to the Purchased Assets or the Partially Exclusive Patents that arose or required performance prior to the Effective Date;

(b) any obligations and liabilities related to [ * ]; and

(c) any obligations and liabilities related to the Excluded Assets, whether arising prior to, on or after the Effective Date.

SECTION 4. CONSIDERATION AND RELATED MATTERS.

4.1 Purchase Price. In consideration for the sale, assignment, transfer, conveyance and delivery of the Purchased Assets to the Purchaser, the Purchaser shall: (a) on the Effective Date, pay to the Seller, by wire transfer of immediately available funds, a non-refundable, non-creditable amount equal to EIGHTEEN MILLION DOLLARS ($18,000,000) (the “Purchase Price”); (b) on the Effective Date, assume the Assumed Liabilities; and (c) on or before the first (1^st) anniversary of the Effective Date, pay to the Seller, by wire transfer of immediately available funds to an account or accounts designated by the Seller, a non-refundable, non-creditable amount equal to FOUR MILLION FIVE HUNDRED THOUSAND DOLLARS ($4,500,000) (such payment, the “First Anniversary Payment”). The Purchaser’s obligation with respect to the First Anniversary Payment shall not be cancelable or conditioned upon any performance, rights or obligations of any Party under this Agreement or the Contract Research Agreement.

4.2 Transfer Taxes. The Purchaser and the Seller shall each bear and pay 50% of any transfer, documentary, sales (imposed by the State of Oregon), stamp, registration and other similar Taxes and all conveyance fees, recording charges and other similar fees and charges that may become payable (whether by the Seller or the Purchaser) in connection with the sale of the Purchased Assets to the Purchaser, the assumption of the Assumed Liabilities by the Purchaser or any of the other transactions contemplated by this Agreement. The Purchaser shall bear 100% of all use Taxes in connection with the use or relocation of the Purchased Assets and any sales Taxes imposed by any state other than the State of Oregon. For the avoidance of doubt, the Seller shall be solely responsible for all Taxes imposed upon the Seller with respect to any income or gain recognized by the Seller as a result of (a) the sale of the Purchased Assets to the Purchaser, (b) the assumption of the Assumed Liabilities by the Purchaser and (c) the other transactions contemplated by this Agreement.

4.3 Allocation. Except for the portion of the Purchase Price allocated to the purchase of the Purchased Facility, which has been agreed upon by the Parties prior to the Effective Date, as soon as practicable after the Closing, the Purchaser will deliver to the Seller a statement allocating the Purchase Price, the First Anniversary Payment (excluding the portion thereof required to be treated as interest for U.S. federal income tax purposes), and the Assumed Liabilities (to the extent relevant) among the Purchased Assets (the “Allocation Statement”) in a manner consistent with Section 1060 of the Internal Revenue Code. If within fifteen (15) days after the delivery of the Allocation Statement, the Seller, in a manner consistent with Section 1060 of the Internal Revenue Code, objects to the allocation set forth in such Allocation Statement, the Purchaser and the Seller will negotiate with each other in good faith and will use commercially reasonable efforts to resolve such dispute within thirty (30) days. If the Purchaser and the Seller reach agreement on such allocation, then each of them will timely file IRS Form 8594 and report all relevant matters consistently with such agreement.

4.4 Real Estate Transaction Expenses. The Purchaser shall bear one hundred percent (100%) of all fees and costs incurred in connection with the transfer of the Purchased Facility at Closing, such as title insurance costs, documentation fees, any survey costs and other similar fees and costs.

SECTION 5. REPRESENTATIONS AND WARRANTIES.

5.1 By the Seller. As of the Effective Date, except as set forth in the corresponding Sections or subsections of the disclosure schedule delivered to the Purchaser on the Effective Date (collectively, the “Disclosure Schedule”) (each of which shall qualify the specifically identified Sections or subsections hereof to which such Disclosure Schedule relates or such other representations and warranties where it is reasonably apparent on the face of such disclosure that such disclosure is applicable to such representations or warranties), the Seller hereby represents and warrants to the Purchaser as follows:

(a) Purchased Assets. Either EPS or Agrinomics owns and has good and valid title to the Purchased Assets (other than to the Intellectual Property Rights included in the Purchased Patents and the Purchased Know-How), free and clear of all Encumbrances, except for Permitted Encumbrances.

(b) Partially Exclusive Patents and Non-Exclusive Assets. EPS or Agrinomics Controls the Partially Exclusive Patents and the Non-Exclusive Assets and has the right to grant to the Purchaser the licenses thereto set forth in Sections 1.3 and 1.4.

(c) Intellectual Property.

(i) Except as set forth in Section 5.1(c)(i) of the Disclosure Schedule, either EPS or Agrinomics owns all right, title and interest in the Purchased Know-How and the Purchased Patents expressly listed on Schedule 1.1(c) (the “Listed Patents”), free and clear of all Encumbrances except for (A) Permitted Encumbrances, (B) the rights granted to Third Parties pursuant to the Purchased Assigned Agreements, (C) the rights granted to the Purchaser and the Purchaser’s Affiliates pursuant to the [ * ] and (D) [ * ].

(ii) Except for the previously granted rights identified in Section 5.1(c)(i) and the previously granted licenses and options described in Sections 1.3(b), 1.3(c) and 1.3(d), and the obligation to grant licenses pursuant to such options, (A) no Third Party has any rights, including any license (whether royalty-bearing or royalty-free) from EPS or Agrinomics to any Purchased Know-How, Listed Patents or Partially Exclusive Patents, and (B) neither EPS nor Agrinomics is subject to any obligation to grant rights to such Intellectual Property Rights to any other Third Party.

(iii) The Listed Patents, the Partially Exclusive Patents and the Non-Exclusive Patents: (A) have not been the subject of any prior litigation or administrative proceeding; (B) are not the subject of any pending litigation or administrative proceeding; (C) are not the subject(s) of any Claim for which the Seller has received written notification; and (D) are not the subject of any threatened Claim of which the Seller has knowledge. For purposes of this Section 5.1(c)(iii), “administrative proceeding” shall mean an opposition, revocation, reexamination, interference or similar proceeding in any country.

(iv) The consummation of the transactions contemplated hereby will not result in the loss or impairment of any of the Intellectual Property Rights included in Purchased Know-How, the Listed Patents, the Partially Exclusive Patents or the Non-Exclusive Assets.

(v) To the knowledge of Seller, no Third Party is currently infringing, misappropriating or otherwise violating, any of the Intellectual Property Rights included in the Purchased Know-How, the Listed Patents, the Partially Exclusive Patents or the Non-Exclusive Assets.

(vi) The Seller has not received from any Third Party any written notification of alleged infringement, misappropriation or other violation of any Intellectual Property Rights of any Third Party arising from the Seller’s development or use of any tangible Purchased Assets or any Intellectual Property Rights included in the Purchased Know-How, the Listed Patents, the Partially Exclusive Patents or the Non-Exclusive Assets, and the Seller does not reasonably believe that the Seller’s development or use, prior to the Effective Date, of any tangible Purchased Assets or use of any Intellectual Property Rights included in the Purchased Know-How, Listed Patents, the Partially Exclusive Patents or the Non-Exclusive Assets constituted infringement, misappropriation or other violation of any valid and enforceable Intellectual Property Rights of any Third Party.

(d) Purchased Assigned Agreements. The Exelixis Existing Agreements and the Purchased Assigned Agreements constitute all contracts, agreements, arrangements or understandings, whether written or oral, to which EPS or Agrinomics is a party, that grant to any Third Party rights to any Purchased Assets. EPS has delivered to the Purchaser accurate and complete copies of each Purchased Assigned Agreement, including all amendments thereto. Each Purchased Assigned Agreement is valid, binding and enforceable (subject to applicable limitations on such enforcement based on bankruptcy laws and other debtors’ rights) and is in full force and effect. Neither EPS nor Agrinomics, nor to the knowledge of the Seller, any other party, is in breach or violation of, or (with or without notice or lapse of time or both) default under, any Purchased Assigned Agreement, nor has either EPS or Agrinomics received any written claim of any such breach, violation or default.

(e) Sufficiency.

(a) If a party entitled to be indemnified under this Section 6 (an “Indemnified Party”) wishes to assert an indemnification claim against the party subject to such indemnification obligation under this Section 6 (the “Indemnifying Party”), the Indemnified Party will deliver to the Indemnifying Party, as soon as reasonably practicable, a written notice (a “Claim Notice”) setting forth: (i) the specific representation, warranty or covenant alleged to have been breached by the Indemnifying Party or the specific other matter with respect to which the Indemnified Party is making such an indemnification claim; (ii) a reasonably detailed description of the facts and circumstances giving rise to the alleged breach of such representation, warranty or covenant or other matter; and (iii) a reasonably detailed description of, and a good faith estimate of the total amount of, the Damages actually incurred or expected to be incurred by the Indemnified Party as a result of such alleged breach or other matter, which estimate shall not limit the indemnification obligations of any Indemnifying Party hereunder. Notwithstanding anything to the contrary contained in this Agreement, the Indemnified Party will not be permitted to deliver any Claim Notice to the Indemnifying Party (and will not be entitled to assert any claim set forth in any Claim Notice) unless the Indemnified Party has reasonably determined that the breach alleged in such Claim Notice has actually occurred or, in the case of indemnification with respect [ * ], that [ * ] or its licensee has actually filed or threatened in writing to file a suit that names one or more Purchaser Indemnitees and alleges infringement of [ * ] by the Purchaser or DAS [ * ], or by EPS or its Affiliates, prior to the Effective Date.

(b) The Claims Period will begin on the date hereof and will terminate and expire, and will cease to be of any force or effect as follows: with respect to Damages arising from or otherwise relating to (i) any breach of the Core Representations, on the date that is the [* ], (ii) any breach of a covenant herein, [ * ] and (iii) any breach of any representation or warranty other than a Core Representation, [ * ].

(g) Without limiting the effect of any other limitation set forth in this Section 6.3, for purposes of this Agreement, no representation or warranty of the Indemnifying Party shall be deemed to have been breached if the Indemnified Party had knowledge, on or prior to the Effective Date, of the inaccuracy in or breach of such representation or warranty or of any facts or circumstances constituting or resulting in an inaccuracy in or breach of such representation or warranty.

(h) The amount of any Damages for which indemnification is provided under this Section 6 shall be calculated net of any actual Tax benefit received by the Indemnified Party or any Affiliate of the Indemnified Party in connection with such Damages or any of the events or circumstances giving rise or otherwise related to such Damages. If the Indemnified Party or any Affiliate of the Indemnified Party actually receives a Tax benefit after an indemnification payment is made, the Indemnified Party shall promptly pay the amount of such Tax benefit to the Indemnifying Party at such time or times as and to the extent that such Tax benefit is realized, but only to the extent of the aggregate related indemnification payments made to the Indemnified Party by the Indemnifying Party.

(i) To the extent the Indemnifying Party makes or is required to pay Damages to the Indemnified Party under this Section 6, the Indemnifying Party will be entitled to exercise, and will be subrogated to, any rights and remedies (including rights of indemnity, rights of contribution and other rights of recovery) that the Indemnified Party or any of the Indemnified Party’s Affiliates may have against any other Person with respect to any Damages, circumstances or Claim to which such indemnification payment is directly or indirectly related. The Indemnified Party will take such actions (at the sole expense of the Indemnifying Party) as the Indemnifying Party may reasonably request for the purpose of enabling the Indemnifying Party to perfect or exercise the Indemnifying Party’s right of subrogation hereunder.

(j) Promptly after the Indemnified Party becomes aware of any event or circumstance that could reasonably be expected to constitute or give rise to any indemnification claim by the Indemnified Party under this Section 6, the Indemnified Party shall take all commercially reasonable steps to mitigate and minimize all Damages that may result from such event or circumstance.

(k) Neither Party shall have any right to set-off, against payments owed by such Party pursuant to this Agreement or the Contract Research Agreement, any amount of Damages incurred by such Party or its respective indemnitees for which the other Party has not yet fulfilled its obligation to indemnify such Party or its respective indemnitees.

If the Indemnifying Party elects to assume the defense of such Claim, then:

(i) notwithstanding anything to the contrary contained in this Agreement, the Indemnifying Party will not be required to pay or otherwise indemnify the Indemnified Party against any attorneys’ fees or other expenses incurred on behalf of the Indemnified Party in connection with such Claim following the Indemnifying Party’s election to assume the defense of such Claim unless (A) the employment of such counsel shall have been specifically authorized in writing by the Indemnifying Party, (B) the named parties to the Third Party Claim (including any impleaded parties) include both the Indemnified Party and the Indemnifying Party, and the Indemnified Party reasonably determines that representation by counsel to the Indemnifying Party of both the Indemnifying Party and such Indemnified Party may present such counsel with a conflict of interest, or (C) the Purchaser is defending a [ * ] Claim;

8.4 Headings. The bold-faced headings contained in this Agreement are for convenience of reference only, shall not be deemed to be a part of this Agreement and shall not be referred to in connection with the construction or interpretation of this Agreement.

8.5 Counterparts and Exchanges by Electronic Transmission or Facsimile. This Agreement may be executed in several counterparts, each of which shall constitute an original and all of which, when taken together, shall constitute one agreement. The exchange of a fully executed Agreement (in counterparts or otherwise) by electronic transmission, including by email, or facsimile shall be sufficient to bind the parties hereto to the terms and conditions of this Agreement.

8.6 Governing Law. This Agreement shall be construed in accordance with, and governed in all respects by, the internal laws of the State of New York (without giving effect to principles of conflicts of laws).

8.7 Dispute Resolution.

(a) In the event of a claimed breach of this Agreement by either Party, or any other dispute arising out of or related to this Agreement, the Parties shall try to settle their differences amicably between themselves by first referring the disputed matter to the respective heads of research of each Party, and if not resolved by such research heads, by referring the disputed matter to the respective Chief Executive Officers of each Party. Either Party may initiate such informal dispute resolution by sending written notice of the dispute to the other Party, and within [ * ] after receipt of such notice, such representatives of the Parties shall meet either in person or by teleconference or video conference to attempt in good faith to resolve any such dispute. If such personnel are unable to resolve such dispute within [ * ] of their first meeting, either Party may initiate arbitration by following the procedures set forth in the commercial arbitration rules of the American Arbitration Association (“AAA”) in effect on the Effective Date (the “AAA Rules”). Within [ * ] of the date provided for any answering statement to be filed by the answering Party, each Party shall select an arbitrator from AAA’s National Roster who is experienced in the field of biotechnology, preferably plant biotechnology, and shall provide written notice thereof to the other Party and to AAA. The two (2) arbitrators so selected shall mutually select a third (3^rd) arbitrator from AAA’s National Roster who is experienced in the field of biotechnology, preferably plant biotechnology. The arbitration shall be conducted in accordance with the procedures set forth below and under the AAA Rules in the

Denver, Colorado office of the AAA. The arbitrators so selected shall hold a preliminary conference with the Parties within [ * ] after their appointment, at which they will schedule a date for the arbitration hearing that will accommodate no more than [ * ] for pre-hearing discovery. The arbitrators shall render their decision after the hearing, in writing, as expeditiously as is possible, and such decision shall be delivered based on written materials submitted by the Parties to the arbitrators and on any oral presentation or testimony offered at the hearing, but provided that neither Party shall be required to attend any such hearing except that individual representatives of the Parties may be required by subpoena to testify at the hearing as ordered by the arbitrators. Each Party shall supply to the other Party a copy of any written materials to be submitted to the arbitrators at least [ * ] prior to the scheduled hearing. A default judgment may be entered against any Party that fails to provide written materials to the other Party for the arbitration hearing. The decision of the three arbitrators shall be final, binding and unappealable and shall be filed as a judgment or record in any court having proper jurisdiction. [ * ].

(b) Discovery shall be (i) limited to the exchange of and timely responding to document requests, interrogatories, and depositions, not to exceed [ * ] per witness, (ii) limited to information directly relevant to the disputed issues and (iii) take into account claims of privilege, work product and other restrictions on discovery as appear to be warranted. The Parties shall comply with the AAA Rules and the scheduling order issued by the arbitrators in serving and responding to discovery.

(c) The arbitrators may award the prevailing Party its attorneys’ and experts’ fees and disbursements incurred in resolving the dispute and may award other sanctions to the extent the arbitrators find any dispute advanced in the proceedings to be frivolous or without a good faith basis in fact and in law when the dispute was first presented for arbitration.

(d) The arbitration shall be absolutely confidential. As a condition precedent to the nomination or appointment of any person as arbitrator, such person shall execute a confidentiality agreement with the Parties (“Arbitrator Confidentiality Agreement”). Participation in the arbitration shall be strictly limited to employees, agents, experts and counsel for the respective Parties with an absolute “need to know”, and to Third Party witnesses with relevant information that testify as ordered by the arbitrators. The identities of all such employees, agents, experts, counsel of a Party and necessary Third Party witness shall be disclosed to the other Party before such employee, agent, expert, counsel or necessary Third Party witness participates in arbitration. All pleadings, briefs and other written submissions shall be presented solely to the arbitrators and exchanged between the Parties; copies shall not be lodged with the AAA. All evidence likewise shall be presented solely to the arbitrators. No copies of any submission by a Party or any documentary evidence presented by a Party shall be made by the other Party or any of the arbitrators except as necessary to prosecute or defend against claims at issue in the dispute. The award shall not disclose any Confidential Information of any Party. Promptly following the award, all submissions and documentary evidence presented by a Party shall be returned to that Party by the other Party and by each of the arbitrators, provided that neither of the Parties, as opposed to the arbitrators, shall be obligated to return the submissions and documentary evidence presented by the other Party until such time as the award is satisfied.

(e) Any issue concerning the extent to which any dispute is subject to arbitration, or concerning the applicability, interpretation, or enforceability of this Section 8.7, including any contention that all or any part of this Section 8.7 is invalid or unenforceable, shall be governed by the Federal Arbitration Act and resolved by the arbitrators, not the court.

8.8 Injunctive Relief.

(a) Each party hereto acknowledges and agrees that any violation of the terms of this Agreement may result in irreparable injury and damage to the other parties hereto that may not be adequately compensable in money damages, and for which the other parties hereto will have no adequate remedy at law. Each party hereto therefore consents and agrees that the other parties hereto may obtain such interlocutory injunctions, orders and decrees as may be necessary to enforce their respective rights under this Agreement, which rights shall be cumulative and in addition to any other rights or remedies to which such parties may be entitled.

(b) [ * ]

8.9 Successors and Assigns; Parties in Interest. This Agreement shall be binding upon and inure to the benefit of the Seller and their successors and assigns (if any) and the Purchaser and its successors and assigns (if any). Except as set forth in Section 2.2(d), none of the provisions of this Agreement is intended to provide any rights or remedies to any Person other than the parties to this Agreement and their respective successors and assigns (if any).

8.10 Waiver. No failure on the part of any Person to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any Person in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy.

8.11 Amendments. This Agreement may not be amended, modified, altered or supplemented other than by means of a written instrument duly executed and delivered on behalf of the Purchaser and the Seller (and, if such amendment affects Section 6, 7.3 or Section 8.1, Mycogen and Exelixis, or if such amendment affects Section 8.15, Exelixis).

8.12 Severability. In the event that any provision of this Agreement, or the application of any such provision to any Person or set of circumstances, shall be determined to be invalid, unlawful, void or unenforceable to any extent, the remainder of this Agreement, and the application of such provision to Persons or circumstances other than those as to which it is determined to be invalid, unlawful, void or unenforceable, shall not be impaired or otherwise affected and shall continue to be valid and enforceable to the fullest extent permitted by law.

8.13 Entire Agreement. The Transactional Agreements set forth the entire understanding of the parties relating to the subject matter thereof and supersede all prior agreements and understandings among or between any of the parties relating to the subject matter thereof.

8.14 Assignment. None of the Seller, the Purchaser, Mycogen nor Exelixis may assign any of their respective rights or delegate any of their respective obligations under this Agreement to any other Person without the prior written consent of the other parties hereto, provided that the Seller and the Purchaser may assign all of their respective rights and obligations under this Agreement, but not less than all, without such consent to any of their respective Affiliates or to their respective successors in interest in connection with the sale of all or substantially all of their respective assets to which this Agreement pertains, through merger, acquisition or other similar transactions.

8.15 Non-Competition.

(a) For a period of [ * ] (the “Covered Period”), EPS, Agrinomics and Exelixis and their respective Affiliates, other than a Permitted Affiliate, shall not for themselves or for any other Person: [ * ]. A “Permitted Affiliate” shall mean a Person who acquires all or substantially all of the stock or assets of EPS, Agrinomics or Exelixis.

(b) Each of EPS, Agrinomics and Exelixis acknowledges that the covenants of EPS, Agrinomics and Exelixis set forth in this Section 8.15 are an essential element of this Agreement and that any breach by EPS, Agrinomics or Exelixis of any provision of this Section 8.15 will result in irreparable injury to the Purchaser. Each of EPS, Agrinomics and Exelixis have independently consulted with their counsel and after such consultation agrees that the covenants set forth in this Section 8.15 are reasonable and proper to protect the legitimate interest of the Purchaser.

8.16 Expenses. Except as otherwise provided herein, all fees and expenses payable in connection with the consummation of the transactions contemplated by this Agreement shall be borne by the party incurring the fees or expenses or seeking such consent or approval.

8.17 Construction.

(a) For purposes of this Agreement, whenever the context requires: the singular number shall include the plural, and vice versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include the masculine and feminine genders.

(b) The parties hereto agree that any rule of construction to the effect that ambiguities are to be resolved against the drafting party shall not be applied in the construction or interpretation of this Agreement.

(c) As used in this Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.”

(d) Except as otherwise indicated, all references in this Agreement to “Sections,” “Exhibits” and “Schedules” are intended to refer to Sections of this Agreement and Exhibits and Schedules to this Agreement. The Exhibits and Schedules attached hereto are deemed to be part of this Agreement as if fully set forth herein.

Kittle, Ph.D., vice president of Research and Development for Dow AgroSciences.
