Adm. Code 742.1020 by and between R& K Petroleum, Inc., an Illinois corporation, referred to herein as "Owner/Operator", and the City of Elgin ("City"). The Owner/Operator and City are referred to as"Parties." 1. This Agreement is not binding upon the City until it is signed by the undersigned representative of the City and before signing, this Agreement constitutes an offer by Owner/Operator. The duly authorized representative of Owner/Operator has signed this Agreement, and this Agreement is binding upon it, its successors and assigns, upon execution by the City. 2. Owner/Operator Stipulates: a. Owner/Operator is pursuing Corrective Action for the property located at 1725 Larkin Avenue, Elgin, Illinois ("the Site"). The Illinois Emergency Management Agency has assigned Incident Numbers 871107 and 922846 to this matter. The property located at 1725 Larkin Avenue, Elgin, Illinois and Numbers 871107 and 922846 is sometimes collectively referred to as "the Site" or "Incident Numbers 871107 and 922846." As part of the Owner/Operator's Corrective Action, the Owner/Operator and the City have entered into a Highway Authority Agreement (the "HAA") for the roads Larkin Avenue and Lyle Avenue ("Rights-of-Way") located along the property frontage, which HAA (including its exhibits) is attached hereto as Exhibit 1 and made a part hereof. The City has agreed to prohibit the use of groundwater as a potable water supply within the area of the corporate limits of Elgin described and depicted in the HAA. For purposes of this agreement, "Corrective Action" is defined as active remediation, passive remediation, investigation and monitoring of "Contaminants of Concern" which are defined as those contaminants released from the Site which have possibly impacted soil/and or groundwater within the Rights-of-Way or within the area covered by the HAA in excess of applicable Tier 1 objectives as described in the HAA, or any combination of these activities defined herein. b. Attached as Exhibits A and B to the HAA are; (i) site maps prepared by Owner/Operator which show the area of estimated contaminated soil and/or groundwater at the time of this Agreement in the Rights-of-Way above Tier 1 residential levels under 35 Ill. Adm. Code 742; and (ii)tables prepared by Owner/Operator showing concentrations of Contaminants of Concern, hereafter "Contaminants," in soil and/or groundwater within the area described in Exhibit A and which shows the applicable Tier 1 soil remediation objectives for property and Tier 1 objectives for groundwater of the Illinois Pollution Control Board ("IPCB") that are exceeded. The Rights-of-Way, and only the Rights-of-Way, as described in Exhibit C of the HAA, adjacent to the Site and adjoining property is subject to this Agreement. As the drawings in the Exhibits are not surveyed plats, the boundary of the Rights-of-Way in the Exhibits may be an approximation of the actual Rights-of-Way lines. Contaminants have been delineated into the Rights-of-Way, the Owner/Operator has represented that the area of the Rights-of-Way is adequate to encompass soil and groundwater in the Rights-of-Way possibly impacted with Contaminants from a release at the Site. c. The Illinois Emergency Management Agency has assigned Incident Numbers 871107 and 922846 to this matter. d. Owner/Operator intends to request risk-based, site specific soil and/or groundwater remediation objectives from the Illinois Environmental Protection Agency ("IEPA")under 35 I11. Adm. Code 742. e. Under these rules, use of risk-based, site specific remediation objectives in the Rights-of-Way may require the use of a highway authority agreement as defined in 35 Ill. Adm. Code 742.1020, in substantially the form of the HAA. 3. The City stipulates that: The City holds a fee simple interest or a dedication for highway purposes in the Rights- of-Way, or the Rights-of-Way are platted streets, and has jurisdiction of the Rights-of-Way. As such, the City exercises access control over the use of the groundwater beneath the Rights-of- Way and over access to the soil beneath the Rights-of-Way. 4. The Parties stipulate that: a. Contemporaneously with the execution of this Agreement, R& K Petroleum, Inc. and the City have executed the HAA attached hereto as Exhibit 1, and will submit the executed HAA to the IEPA. Under 35 Ill. Adm. Code 742.1020, this Agreement is intended to establish undertakings by the Owner/Operator to the City in consideration of the City entering into the HAA and the City's agreements herein that it will not allow the use of groundwater under the Rights-of-Way as a potable or other domestic supply of water, and that it will limit access as described herein to soil under the Rights-of-Way that is contaminated from the release at levels above residential Tier 1 remediation objectives. b. The IEPA and/or Attorney General ("AG") must review and approve the HAA, and the HAA shall be referenced in IEPA's "No Further Remediation" determination in the chain of title for the Site in the county where the Site is located. c. This Agreement shall be null and void should the IEPA or AG not approve the HAA, or should the HAA not be referenced in the "No Further Remediation" determination, provided, however, that this Agreement shall be effective between the Owner/Operator and the City immediately upon signature by their representatives. 5. The City promises IEPA and the Owner/Operator that it will prohibit the use of groundwater that is contaminated from the release at the Site at levels above Tier 1 residential remediation objectives beneath its Rights-of-Way within the area covered by the HAA as a potable or other domestic supply of water and that it otherwise will limit access to soil as described herein under the Rights-of-Way that is impacted from the release at levels above Tier 1 residential remediation objectives. As the pavement in the Rights-of-Way may be considered an engineered barrier, the Owner/Operator agrees to reimburse the City for such maintenance 2 activities requested by Owner/Operator or the IEPA in writing as are reasonably necessary to maintain such pavement area(s) as a barrier. The City does not otherwise agree to perform maintenance of the Rights-of-Way, nor does it agree that the Rights-of-Way will always remain a highway or that it will maintain the Rights-of-Way as an engineered barrier. 6. The Owner/Operator agrees to indemnify and hold harmless the City and other highway authorities, if any, maintaining the Rights-of-Way by an agreement with the City and the City's agents, contractors, officials, officers and employees for all lawsuits, claims, losses, injuries, damages,judgments, or other obligations asserted against or costs incurred by them, including reasonable attorney's fees and court costs(collectively, "Obligations"), associated with the release of Contaminants of Concern regardless whether said obligations or costs were caused by the negligence of them. 7. As an additional consideration, and subject to the requirements of paragraph 12, Owner/Operator agrees to reimburse the City for those reasonably necessary costs it has incurred or will incur in responding appropriately to the suspected presence of Contaminants of Concern in the Rights-of-Way as a result of the release of contaminants at this Site, including but not limited to, identifying, investigating, handling, storing and disposing of contaminated soil and groundwater in the Rights-of-Way as a result of the release of Contaminants at this Site by Owner/Operator. Owner/Operator further agrees to reimburse the City for those reasonably necessary costs it has incurred in the amount of $1,500.00 in reviewing and negotiating this Agreement. A check made payable to "The City of Elgin" shall be tendered to the City by the Owner/Operator in the amount of$1,500.00 concurrently with the execution of this Agreement. 8. This Agreement shall be binding upon all successors in interest to the Owner/Operator or Rights-of-Way. A successor in interest of the City would include a highway authority to which the City would transfer jurisdiction of the highway. 9. Violation of the terms of this Agreement by Owner/Operator, or by the City, may be grounds for voidance of this Agreement. Violation of the terms of the HAA by the City will not void this Agreement, unless the IEPA has determined that the violation is grounds for voiding the HAA and the City has not cured the violation within such time as IEPA has granted to cure the violation. 10. This Agreement shall continue in effect from the date of this Agreement until a) the Rights-of-Way are demonstrated to be suitable for unrestricted use, b) there is no longer a need for the HAA, and c) the IEPA has, upon written request to the IEPA by the Owner/Operator and notice to the City, amended the notice in the chain of title for the site to reflect unencumbered future use of that Rights-of-Way. 11. This Agreement constitutes full settlement of claims the City may have arising from the possible release of Contaminants of Concern associated with Incident Numbers 871107 and 922846, and is not in settlement of claims of the IEPA or any other State Agency. 12. This Agreement does not limit the City's ability to construct, reconstruct, improve, repair, maintain and operate a highway upon its property or to allow others to use the Rights-of- 3 Way by permit.To that extent,the City reserves the right,and the right of those using or working in its Rights-of-Way under permit, to remove contaminated soil or groundwater above Tier 1 residential objectives from its Rights-of-Way and to dispose of them as they deem appropriate, in accordance with applicable environmental regulations, so as to avoid causing a further release of the Contaminants and to protect human health and the environment. Prior to taking any such action, the City may, if practicable as determined by the City, first give Owner/Operator written notice that it intends to perform a site investigation in the Rights-of-Way and remove or dispose of contaminated soil or groundwater to the extent necessary for its work. Failure to give notice shall not constitute a violation of this Agreement. The removal or disposal shall be based upon the site investigation (which may be modified by field conditions during excavation), which Owner/Operator may review or may perform, if requested to do so by the City. If practicable, as determined by the City, the City may request Owner/Operator to remove and dispose of the contaminated soil and/or groundwater necessary for the City's work in advance of that work. The Owner/Operator shall reimburse the reasonable costs incurred by the City to perform the site investigation and to dispose of any contaminated soil or groundwater regardless of whether notice has been given to Owner/Operator. There is a rebuttable presumption that the Contaminants found in the highway Rights-of-Way arose from the release of Contaminants from the Site. Should Owner/Operator not reimburse the reasonable costs under the conditions set forth herein, this Agreement shall be null and void, at the City's option, upon written notice to Owner/Operator by the City that those costs have not been reimbursed. Owner/Operator may cure that problem within twenty (20) working days by making payment. Failure to give notice to the Owner/Operator or failure to give the Owner/Operator the opportunity to remove and dispose of contaminated soil and/or groundwater is not a violation of this Agreement and shall not be a defense to a claim for reimbursement or the work should not have been done. Should Owner/Operator not reimburse the costs identified herein, this Agreement shall be null and void in addition to such other remedies as may be available to the City by law. Notwithstanding any termination of this Agreement, the City shall have the right to enforce the reimbursement obligations of Owner/Operator, and the City shall be entitled to recover all of its reasonable costs (including attorneys' fees) in connection with such enforcement. 13. Written Notice required by this Agreement must be mailed to the following: If to the Owner/Operator: If to the City: R&K Petroleum, Inc.

The City's sole responsibility under this Agreement with respect to others using the Rights-of-Way under permit from the City is to include the following, or similar language, in the future standard permit provisions and to make an effort to notify its current permit holders of the following: As a condition of this permit, the permittee shall request the City's Public Works Department to identify sites in the Right-of-Way where access to contaminated soil or groundwater is governed by Tiered Approach to Corrective-Action Objectives ("TACO") Agreements. The permittee shall take measures before, during and after any access to these sites to protect worker safety and human health and the environment. Excavated, contaminated soil should be managed off-site in accordance with all environmental laws. Owner/Operator hereby releases the City from liability for breach of this Agreement or the HAA by others under permit and indemnifies the City against claims that may arise from others under permit causing a breach of this Agreement or the HAA. Owner/Operator agrees that its personnel, if any at the Site who are aware of the HAA, will notify anyone they know is excavating in the Rights-of-Way about the HAA. 15. Should the City breach this Agreement or the HAA, Owner/Operator's sole remedy is for an action for damages in the Circuit Court for the 16th Judicial Circuit, Kane County, Illinois. Any and all claims for damages against the City, its agents, contractors, employees or its successors in interest arising at any time for a breach of this Agreement or the HAA are limited to an aggregate maximum of One Thousand Five Hundred Dollars ($1,500). No other breach by the City, its agents, contractors, employees and its successors in interest of a provision of this Agreement or the HAA is actionable in either law or equity by Owner/Operator against the City or them, and Owner/Operator hereby releases the City, its agents, contractors, employees and its successors in interest for any cause of action it may have against them, other than as allowed in this paragraph, arising under this Agreement or environmental laws, regulations or common law governing the impacted soil or groundwater in the Rights-of-Way or in the area covered by the HAA. Should the City convey, vacate or transfer jurisdiction of that Rights-of-Way, Owner/Operator may pursue an action under this Agreement against the successors in interest, other than a State Agency, in court. 16. This Agreement is entered into by the City in recognition of laws passed by the General Assembly and regulations adopted by the IPCB which encourage a tiered-approach to remediating environmental contamination. This Agreement is entered into by the City in the spirit of those laws and under its right and obligations as property owner. Should any provisions of this Agreement be struck down as beyond the authority of the City, however, this Agreement 5 shall be null and void, except that all costs and expenses to be paid by Owner/Operator as provided in this Supplemental Agreement which have been incurred by the City prior to termination shall be reimbursed by Owner/Operator within 45 days after the Supplemental Agreement becomes null and void, and Owner/Operator's obligations under Paragraph 6 of this Supplemental Agreement shall survive any termination of this Supplemental Agreement.
