To the best of Seller's knowledge, the current operations of the Refinery and the other Purchased Assets and the use of the Proprietary Rights do not infringe any valid issued patent, or other right of any third party. No claim by any third party contesting the validity, enforceability, use or ownership of the Proprietary Rights is currently outstanding or, to the best of Seller's knowledge, is threatened. Except as disclosed on such Schedule, any such Proprietary Rights may be assigned or sublicensed (with respect to those Proprietary Rights to be sublicensed to Buyer pursuant to the Technology Transfer and License Agreement) to Buyer without the consent of any third party. L. Actions and Proceedings. (i) Except as set forth on Schedule H, there is no action, suit, arbitration proceeding or claim pending, or, to Seller's knowledge, threatened against Seller or any of its affiliates, involving or affecting the Purchased Assets for which Buyer will be responsible or which will adversely affect the Buyer whether seeking relief or redress under Environmental Laws or seeking any injunctive relief, except for such injunctive relief that if granted would be insignificant to any of the Purchased Assets, nor is there any basis known to Seller for any such action, suit, proceeding or claim; and, except as disclosed on Schedule H or Schedule I there are no decrees, injunctions, liens, orders or judgments of or with any court or governmental department or agency outstanding against Seller relating to or affecting the Purchased Assets; and (ii) To Seller's knowledge, except as set forth on Schedule H or Schedule I, no action, suit, arbitration proceeding or claim is pending or threatened seeking to restrain or prohibit this Agreement, or any agreement, instrument or transaction contemplated hereby, or to obtain damages, a discovery order or other relief in connection with this Agreement or the transactions contemplated hereby. 16 (iii) To the best knowledge of Seller, there is no pending or threatened condemnation or other governmental taking of any of the real property included in the Purchased Assets.

(iii) Seller warrants that the data on Schedule P. is materially true and complete. 8. ENVIRONMENTAL. A. Definitions. Terms used in this Section 8. shall have the meanings defined below. (i) "Compliance Action" means any activity reasonably necessary to cause any storage tank systems, any pollution control equipment, structure, device, plan or process, or any other equipment, structure, device, plan or process subject to regulation pursuant to Environmental Laws, located at the Refinery or the other Purchased Assets to be in compliance with applicable Environmental Laws in effect at the Closing Date. Compliance Action may include relaxation or postponement of requirements; (ii) "Corrective Action" means all activities, whether undertaken pursuant to judicial or administrative order or otherwise, reasonably necessary to comply with applicable Environmental Laws, to investigate, monitor and, if required, clean up, remove, treat, cover, protect from human or environmental exposure or in any other way adjust Hazardous Substances in the environment at the Refinery or the other Purchased Assets.

C. Environmental Provisions. ------------------------ (i) Division of Responsibility. As set forth in more detail below, Seller shall retain sole responsibility for Corrective Action associated with the approximately 75 Waste Units. As set forth in more detail below, Buyer shall, notwithstanding any provision of Section 8(F) or Section 16 hereof to the contrary, be solely responsible to conduct Corrective Action attributable to Hazardous Substances in or on process equipment, storage tanks, sewers and containment devices or other equipment and improvements at the Refinery or other Purchased Assets at the Closing Date to the extent that the presence of said Hazardous Substances is in compliance with Environmental Laws and the 20 result of normal operations of the Refinery and the other Purchased Assets as the Refinery and other Purchased Assets have been operated on a recent historical basis ("Contained Hazardous Substances"), or demonstrably attributable to operation of the Refinery or other Purchased Assets after the Closing Date. Buyer agrees to be responsible for any Corrective Action attributable to Contained Hazardous Substances present as of the Closing Date, and any contamination caused by Contained Hazardous Substances or related Corrective Action after the Closing Date. Seller remains solely liable for any penalties relating to the ownership or operation of the Refinery or any other Purchased Assets prior to the Closing Date. Seller shall be solely liable for any and all claims, no matter when asserted, for its shipment of, or arranging the shipment of, Hazardous Substances from the Refinery prior to the Closing Date for offsite treatment, storage, processing, recycling, reuse or disposal at any facility. Buyer is responsible for Compliance Actions, and is solely liable for maintaining compliance with requirements applicable to operation of the Refinery and the other Purchased Assets after the Closing Date, except to the extent that Indemnity is provided for breach of a representation.; (ii) Allocation. (a) Presumption. Except as otherwise provided in this Agreement, or specifically agreed in writing, the presence or absence as of Closing of Hazardous Substances in the soil or ground water at the Refinery or other Purchased Assets, or that have migrated or may migrate from the Refinery or other Purchased Assets as a consequence of activities on or related to the Refinery, shall be presumed to be attributable to operation of the Refinery or other Purchased Assets prior to the Closing Date, except as and to the extent that such presence of Hazardous Substances can be shown to be attributable to operation of the Refinery or other Purchased Assets after the Closing Date. Seller shall make available existing data and information generated on or after January 1, 1994, or otherwise relevant to the current environmental status of the Refinery or other Purchased Assets; and (b) Deepwell - Buyer acknowledges that underground injection of material, including hazardous wastes resulting from the local production of acrylonitrile, hydrogen cyanide and other chemicals, ("Deepwell Injection") is conducted by BPC, on property adjacent to the Refinery, 21 and that material and conditions associated with Deepwell Injection may be encountered at depths of over 2,000 feet below the surface under part or all of the Refinery, and that such conditions will exist for the foreseeable future. Buyer hereby expressly releases the BP Group, Seller and BPC, and their successors and assigns from any claims or liability that Buyer might be able to allege in connection with the Deepwell Injection operation, or subsurface migration of materials therefrom, including, without limitation, any claims for diminution in use, enjoyment or value of the Purchased Assets. Notwithstanding any contrary provision herein, Seller agrees to Indemnify Buyer Indemnified Parties against any Losses arising out of or relating to any claims or liability alleged against Buyer Indemnified Parties by any third party (including but not limited to any governmental authority) in connection with or arising out of the Deepwell Injection operation, or subsurface migration of materials therefrom (c) Conduct of Corrective Action. (d) Seller's Obligations For Waste Units. To the extent that Corrective Action for Hazardous Substances attributable to Waste Units as of the Closing Date is required pursuant to any present or future Environmental Law, as in effect and as applied, recognizing the industrial status of the Refinery, at the time of said Corrective Action, Seller shall, as provided herein, undertake at its expense and (unless otherwise agreed between the parties) under its control to conduct such Corrective Action as may be required, on such schedule as may be authorized by applicable governmental authority or Environmental Law, and shall be entitled to the benefit of any applicable reimbursement funds. Any Corrective Action undertaken by Seller may be pursuant to applicable provisions of the Ohio Voluntary Action Program, ORC Sections 3746.01, et seq., and regulations promulgated thereunder. Institutional controls not unreasonably impairing the use of the Refinery and the other Purchased Assets, including deed restrictions, may with Buyer's consent (not to be unreasonably withheld) be incorporated into the Corrective Action, to the extent reasonably necessary to obtain a no further action letter or other regulatory approval. In addition, Seller shall be solely liable for any and all claims no matter when asserted for its shipment of, or arranging for the shipment of, Hazardous 22 Substances in connection with Seller's conduct of Corrective Action for offsite treatment, storage, processing, recycling, reuse or disposal at any facility; (e) Buyer's Obligations. To the extent Buyer undertakes at its expense (subject to any applicable Indemnity from Seller, as provided below) and under its control to conduct Corrective Action at the Refinery or other Purchased Assets (including without limitation Corrective Action with respect to Hazardous Substances at or emanating from the Refinery or other Purchased Assets not attributable to Waste Units as of the Closing Date), Buyer shall be entitled to the benefit of any applicable reimbursement funds. In the event of releases of Hazardous Substances on or after the Closing Date in locations or amounts not readily distinguished from Hazardous Substances known or presumed to be the result of operation of the Refinery or other Purchased Assets prior to the Closing Date, Buyer shall be responsible for the incremental costs of Corrective Action attributable to such releases. Buyer shall provide to Seller information about releases subsequent to the Closing Date sufficient to estimate the incremental costs due to such releases. Buyer and Seller shall work together in good faith to estimate such costs. In the event the parties are unable to reach agreement, the matter may be referred for Dispute Resolution pursuant to Section 16.D.(ii) hereof. Where the projected incremental costs associated with the subsequent release exceed the projected remaining costs for Corrective Action for which Seller is responsible, Buyer shall assume control of the Corrective Action, and Seller shall be responsible only for the increment of costs over the costs attributable to the subsequent release. Seller may either reimburse Buyer for its share of such costs, or may, if the parties so agree, pay a lump sum equal to the present value of projected costs sufficient to complete all corrective actions attributable to Waste Unit conditions as of the Closing Date, and have no further responsibility with respect to such conditions. In the event Buyer assumes control of a Corrective Action pursuation equipment owned by Seller and both located and used at the site of the contamination assumed by Buyer may, at Buyer's option, be conveyed to Buyer in exchange for an agreed price; 23 (f) Cleanup Incentive. Costs expended by or on behalf of Seller for Corrective Action activities required by Section 8. (other than costs to the extent attributable to the Waste Units) shall be aggregated. Such costs shall include any costs resulting from Seller's Indemnification under Section 16.B., to the extent such Indemnification is the result of Corrective Action matters within the scope of Section 8. (other than costs to the extent attributable to Waste Units). Seller shall provide Buyer an annual statement showing expenditures of such costs. Buyer shall have the right to review such non-privileged documents as may be necessary to audit such costs. As of the date twelve years after the Closing Date, the aggregate amount of such costs shall be subtracted from Twenty Million Dollars ($20,000,000). Seller shall pay to Buyer within 45 days after the expiration of said twelve year period and amount equal to one-half of the amount, if any, by which Twenty Million Dollars ($20,000,000) exceeds the aggregate of such costs. Nothing in this section 8.C.(iii.)(c.) shall be construed to limit Seller's responsibility for Compliance Actions or Corrective Actions under this Agreement. D. Buyer's Notice of Intent. Buyer shall provide Seller with 90 day's advance notice, of Buyer's intent, prior to January 1, 2019, to sell the Refinery or to cease or substantially curtail operations at the Refinery, or on 30 days' notice to change the scope, method or nature of operations at the Refinery, including, without limitation, the construction of new or modified structures at the Refinery, or undertaking excavations or geological investigations in connection with such construction, where such would reasonably be expected to lead directly or indirectly, including the consequence of the exercise of governmental agency discretion, to a significant increase in the cost of Corrective Action for which Seller is responsible, or to an acceleration of the timing of Corrective Action, or both. Buyer agrees to impose a similar obligation on purchasers of the Refinery. The parties agree that they will negotiate in good faith during the advance notice period to attempt to find alternatives agreeable to both parties, including without limitation re-purchase or throughput arrangements, which may efficiently or cost-effectively postpone or avoid the incurrence of additional remediation costs to the extent practicable. Buyer's investigation of the Refinery intended to identify contamination by Hazardous substances shall be limited to that (i) required under Environmental Law or other applicable legal requirements, or (ii) which a reasonable experienced refinery operator would undertake considering the totality of the circumstance, but disregarding the existence of any 24 indemnity. It is the intent of Buyer and Seller that consistent with Environmental Laws the costs of the Corrective Actions be avoided or minimized. Buyer shall provide reasonable assistance and cooperation to Seller in efforts to avoid or minimize such costs.; E. Access. (i) Buyer and, if applicable, its designated representative (herein "Owner") will permit access to and entry upon the Refinery and other Purchased Assets to Seller and Seller's designated representatives (herein "Licensee") as necessary to conduct and complete Corrective Actions required pursuant to this Agreement. In the event of a subsequent sale, lease or other transfer of the Refinery and other Purchased Assets, Buyer shall require that Buyer's transferee agree to the access provisions of this Section 8. Such access shall, where necessary, include access to utility connections, easements for installation of treatment facilities and associated pipelines and utilities and connections and use of wastewater treatment facilities. Seller will pay Buyer a reasonable fee pursuant to Utilities and Services Agreements for such utility and treatment facility use and such access will be done in a manner so as not to unreasonably interfere with Buyer's business. Buyer will cooperate in good faith with Seller to ensure adequate and cost effective performance of Corrective Action, including, where appropriate, reasonable institutional controls including deed restrictions, in light of the property's use as an industrial facility, and not unreasonably impairing its value or use for those purposes. Buyer and Seller agree to negotiate in good faith an appropriate Right of Entry Agreement and Utilities and Services Agreement which would provide for any necessary terms and conditions, beyond those identified herein, under which such access and services will be provided; (ii) Except in the event of an emergency, Licensee shall provide Owner with at least five (5) business days notice prior to beginning any drilling, construction, and equipment installation, as well as other activity that may disrupt normal business operations on the Refinery or other Purchased Assets . Licensee's activities shall not cause undue disruption to Owner's business activities; (iii) Owner shall use its reasonable efforts not to unreasonably interfere with the Licensee while Licensee exercises its rights of ingress and egress to perform the Corrective Action. Licensee shall perform the Corrective Action in a manner which 25 minimizes disruption to Owner's business activities and to the Refinery; (iv) Promptly upon completion of a Corrective Action, and except as the Corrective Action may require a change in the appearance or condition of a portion of the Property, Licensee shall restore the Refinery or other property to substantially the condition which existed immediately prior to the commencement of the Corrective Action; (v) Seller shall provide to Owner copies of final reports, drawings, maps, appropriate project, operating and maintenance files, correspondence with any governmental authority, and sampling data related to, or which result from, any actions on the Refinery or other Purchased Assets. Owner shall provide to Licensee copies of any correspondence with or between Owner and any applicable governmental authority which involves or relates to any matters described in this Agreement or which could reasonably impact Licensee's actions at the Refinery or other Purchased Assets. Upon Licensee's reasonable request, Owner shall provide Licensee with such non-privileged final reports, drawings, maps and appropriate project, operating and maintenance records as may be useful for Licensee to examine to determine whether operation of the Refinery or other Purchased Assets has changed after the Closing Date, and whether contamination is or may be the result of operations at the Refinery or other Purchased Assets on or after the Closing Date. Owner shall permit Licensee to examine and copy such financial records as may be useful in determining the reasonableness of expenditures for which Indemnity or reimbursement is claimed; (vi) Prior to and during a Corrective Action, Licensee shall take all steps which are reasonably necessary to prevent injury to persons or damage to property resulting from or in any way connected with the Corrective Action; (vii) Seller shall Indemnify the Owner against any Losses incurred by Owner, and any liens and encumbrances that may be filed or attach against the Refinery or any other Purchased Assets, in connection with actions that Licensee performs on the Refinery or any other Purchased Assets. No contractor, subcontractor, materialman, agent, officer, director or employee of the Licensee shall have any right to a lien against the Refinery or any other Purchased Assets or any part thereof for any work, labor or materials furnished to Licensee for the actions performed on the 26 Refinery or any other Purchased Assets, unless otherwise mandated by applicable law; (viii) Buyer will pay any and all costs, claims, rents or charges which Seller may incur if reasonable access to the Refinery or any other Purchased Assets is not granted in accordance with this Agreement; (ix) Owner agrees to be responsible and reimburse Licensee for any damage or loss that Owner, its employees, agents, lessees, occupants of the Refinery or any other Purchased Assets, contractors, successors or assigns cause, whether sole, joint or concurrent, to any test or monitoring well, remediation equipment and/or associated piping, or any other property or equipment installed or otherwise used by Licensee; and (x) All equipment installed or used in the course of Corrective Action shall remain the property of Licensee, and may be removed upon completion of the Corrective Action. F. Specific Matters. For avoidance of doubt, responsibility for the following matters is allocated as described below: (i) Groundwater Treatment - Except as otherwise agreed, Seller shall continue to own, as necessary, and operate the groundwater recovery and treatment facilities, listed on Schedule L, at the Refinery. Buyer shall, at Seller's cost and request, but subject to there being available capacity, treat any recovered groundwater from Corrective Action operations in the Refinery's wastewater treatment plant. The cost charged by Buyer to Seller for such treatment will equal Buyer's incremental cost of providing such treatment; (ii) Construction - Where Buyer's plans for construction activity will or may cause disturbance of soil, the parties will consult to find the lowest total incremental cost method or location of construction. 9. DISCLAIMER. Except as otherwise expressly set forth in this Agreement and the instruments, documents and agreements referred to herein or executed in connection with the transaction contemplated hereby: (i) Seller makes no representations or warranties of any kind or nature with respect to itself, the Refinery, any portion thereof or ANY OTHER ASSET TRANSFERRED TO BUYER PURSUANT TO THE TERMS OF THIS AGREEMENT and 27 Seller hereby disclaims any implied warranties including without limitation any implied warranties of merchantability or fitness for a particular purpose; (ii) the Refinery AND ANY OTHER ASSETS TRANSFERRED TO BUYER PURSUANT TO THE TERMS OF THIS AGREEMENT, are being transferred "AS IS" and "WITH ALL FAULTS;" and (iii) Seller makes no warranty with respect to the condition of any of the Refinery, the merchantability of the Refinery or the fitness of any assets for any purpose and hereby disclaims any and all warranties and representations of any kind or nature. 10.

The Indemnifying Party will not settle or compromise any third party claim unless such settlement or compromise involves solely the payment of money by the Indemnifying Party and such settlement or compromise includes as an unconditional term 47 thereof the giving by the claimant of a release of the Indemnified Party from all liability with respect to the matters relating to such claim and does not involve any admission of culpability; (iii) The Indemnified Party and the Indemnifying Party will each provide the other full cooperation in the defense of any such action, and shall furnish any documents or endeavor to make available any witnesses under its control; (iv) Except with respect to third-party claims or actions, any recovery from the Indemnifying Party shall be limited to the actual direct Losses, and shall not include punitive damages, consequential damages, lost profits or rents, diminution in the value of real property or business interruption losses incurred by the Indemnified Party; (v) A Buyer Indemnified Party shall not be entitled to make a claim against Seller under paragraph A.(ii) of this Section 16. unless and until (a) Buyer shall have provided Seller written notice of such default; and (b) Seller shall have failed to cure such default within thirty (30) days after Seller's receipt of Buyer's notice; and (vi) A Seller Indemnified Party shall not be entitled to make a claim against Buyer under paragraph B.(ii) of this Section 16. unless and until (a) Seller shall have provided Buyer written notice of default; and (b) Buyer shall have failed to cure such default within thirty (30) days after Buyer's receipt of Seller's notice.

Any claim under Section 8. or Section 16.B.(v), (vi) or (vii) for Indemnity (in each case except to the extent relating to any Waste Unit) shall be brought within seventeen 48 (17) years after the Closing Date.

This provision shall not limit Seller's liability for Excluded Liabilities or for Losses pursuant to the provisions of Section 8. J. Purchase Price Adjustment.

While the Records are in Seller's possession, Buyer shall be allowed reasonable access thereto. B. After the Closing Date, each party will provide such assistance as the other parties may from time to time reasonably request in connection with the preparation of Tax Returns required to be filed, any audit or other examination by any taxing authority, any judicial or administrative proceeding relating to liability for taxes, or any claim for refund in respect of such Taxes or in connection with any litigation and proceedings or liabilities related to the Refinery including making available employees for interviews, litigation preparation and testimony. 50 The requesting party will reimburse the assisting party for the out-of-pocket costs incurred by the assisting party. 19.
