|1010|
FIRST ADDENDUM to INTERGOVERNMENTAL AGREEMENT BETWEEN THE ILLINOIS STATE TOLL HIGHWAY AUTHORITY AND THE CITY OF CHICAGO REGARDING THE ELGIN O'HARE WESTERN ACCESS PROJECT
This First Addendum to Intergovernmental Agreement ("Addendum") is made and entered
into as of 2022 by THE ILLINOIS STATE TOLL HIGHWAY AUTHORITY,
an instrumentality and administrative agency ofthe State of Illinois {"Tollway") and the CITY OF CHICAGO, an Illinois home rule municipality ("City").
RECITALS
WHEREAS, on April 14, 2017, the City and Tollway (collectively, "Parties") entered into an Intergovernmental Agreement ("Agreement") to define their respective responsibilities relative to the Elgin-O'Hare Western Access Project ("EOWA Project), which is a Project of National and Regional Significance (i.e., a project that has national and regional benefits, including economic, congestion relief and safety) as designated by the United States Department of Transportation and the Federal Highway Administration ("FHWA");
WHEREAS, as a material inducement for the City's execution of the Agreement, it was understood and agreed that the EOWA Project would not cause material adverse impacts, even by temporary intrusion or construction interference, on operations at O'Hare International Airport ("Airport"), including but not limited to airfield and runway operations, surrounding navigable airspace and protected surfaces, or any runway classification, instrument rating, or other utility or capability of any runway;
WHEREAS, after reviewing the Environmental Impact Statement ("E/S") for the EOWA Project pursuant to the National Environmental Protection Act ("NEPA"), the FHWA and the Federal Aviation Administration ("FAA") issued a joint Record of Decision ("ROD"), subsequent to which the Illinois Department of Transportation ("IDOT') and the Tollway prepared and submitted EIS Re-Evaluation documents to the FHWA and FAA to address changes to the EOWA Project that were proposed after the ROD was issued;
WHEREAS, following issuance ofthe ROD, Soo Line Railroad Company d/b/a Canadian Pacific Railway's ("CP') filed suit in the Surface Transportation Board ("STB") to challenge alleged impacts the Tollway's original design for the southern leg of I-490 (approved pursuant to the initial ROD) would have on CP's Bensenville Yard, and the Tollway filed a related action in federal court;
WHEREAS, to settle the lawsuits, the Tollway proposed realignment of the southern leg of I-490, thereby shifting a segment of the roadway footprint north of the CP's Bensenville Yard onto a portion of Airport property adjacent to Illinois Route 19 ("Revised 1-490 South Leg'), as depicted on Exhibit G;
WHEREAS, the primary remaining EIS Re-Evaluation element on which approval is pending concerns the Revised 1-490 South Leg, which includes, but is not limited to, construction of a roadway that will carry both 1-490 and Illinois Route 19 traffic between York Road and Taft Avenue, relocation ofthe O'Hare Airport Perimeter Road and Air Operations Area ("AOA") Fence located along the southern boundary of the Airport, reconfiguration of the South Access Road intersection with Illinois Route 19, reconfiguration ofthe Taft Avenue intersection at Illinois Route 19, reconfiguration of the access to the South Airport Surveillance Radar ("South ASR-9"), modification ofthe Runway 10R/28L ALSF-2 system, associated utility relocations, and all other work associated with the plans and specifications;

WHEREAS, while the Tollway has represented to the City that the proposed Revised I-490 South Leg is its preferred plan for the southern leg ofthe 1-490 Project and that the proposed Revised 1-490 South Leg can be designed and constructed without Permanent Impact to Airport operations, including, but not limited to, airfield and runway operations; surrounding navigable airspace and protected surfaces as defined in 14 C.F.R. Part 77 and by the FAA; or any runway classification, instrument rating or other utility or capability of any runway (specifically including the operations and capabilities of Runway 10R/28L), the Tollway recognizes that its preferred plan for construction of the Revised I-490 South Leg may cause material temporary impacts to Runway 10R/28L, including the potential loss of capabilities of the Instrument Landing System ("ILS") serving the runway, for a temporary, but not permanent, period of time ("Temporary Runway 10R/28L Impact);
WHEREAS, subsequent to the Parties' execution of the Agreement, in addition to the Tollway's development of the proposed Revised I-490 South Leg, the Tollway's design and construction planning for certain additional elements of the EOWA Project have proceeded in a manner that requires the Tollway to request the City's accommodation and coordination on short-term Airport operational impact during construction that is not permanent in nature, including but not limited to reconfiguration, respacing and/or relocation of certain ALSF-2 system facilities serving Runways 9L/27, 10L/28R, and 10C/28C;
WHEREAS, in addition to the Temporary Runway 10R/28L Impact and short-term operational impact during modification of the ALSF-2 system facilities serving Runways 9L/27, 10L/28R and 10C/28C, the Revised I-490 South Leg also requires the Tollway to seek title to additional property and additional property rights in Airport property from the City in the form of fee ownership, permanent easement and temporary construction easement property ("City Transfer Property") in the location and manner depicted on Exhibit A;
WHEREAS, the Parties understand and acknowledge that the property in which the Tollway seeks title and property rights is currently obligated for use for Airport purposes pursuant to an FAA-approved Airport Layout Plan ("ALP') attached to the Agreement as Exhibit C, and further acknowledge that the City is obligated to the FAA under certain Airport Sponsor Assurances ("Grant Assurances") which, among other things, prohibit the City from causing or permitting any activity or action on Airport property which would interfere with said Airport property use for Airport purposes. Therefore, the City must obtain FAA approval to convey title and property rights to the Tollway for the purposes sought;
WHEREAS, to support requests for all relevant or required approvals by the FAA of the EIS Re-Evaluation, the Revised I-490 South Leg, the related Airport operational impacts, and associated title and property rights sought by the Tollway, the City and Tollway desire to define
the process, responsibilities and tolerable limitations as to the Temporary Runway 10R/28L Impact and any other Temporary Construction Impact in relation to operations at the Airport, and
a process whereby operational impacts or interruptions exceeding such temporary agreeable tolerances shall be immediately ceased, discontinued and rectified such that, as soon as possible, Airport operations are restored and returned to operating conditions at no less service than prior to such impact or interruption or reasonably agreed to by the Parties;
WHEREAS, the City is completing the O'Hare Modernization Program ("OMP"), including construction of Runway 9C/27C and the Runway 9R/27L extension, and advancing planning and development of the O'Hare 21 capital improvement program ("O'Hare 21"), which includes a series of improvements to the Airport to meet projected air transportation demand including new expanded terminal and gate facilities and employee parking;


|1010|
WHEREAS, the Parties agree that both the OMP and the EOWA Project have established implementation schedules that require the cooperation and timely involvement ofthe other Party for completion in accordance with such schedules;

The improvements on Tollway property include construction of an ALSF-2 system installation (i.e., bridge, lightbars, electrical connections, etc.), installation of a pedestrian bridge, vehicular access from Supreme Drive, parking area, and drainage modifications at Willow Creek. These improvements require the City to seek property rights in Tollway property in the form of permanent easement and temporary construction easement ("Tollway NAV AID Property);
WHEREAS, in addition to the OMP and O'Hare 21, the City is advancing planning of a Western Landside Reserved Area ("WLRA") for development compatible with western access to the Airport;

WHEREAS, the Parties agree that the WLRA site requires construction to manage soil stockpiles in order to enable subsequent economic development and access to the western portion of the Airport and that the scope ofthe WLRA site work described in Section 15.H. ("WLRA Soil Project"), including without limitation modification of portions of the Airport Perimeter Road and AOA Fence and construction of detention basins, will be performed by the Tollway to accommodate western access to the Airport and the City's future development at the WLRA, including but not limited to, a circulation road, parking facilities and other necessary improvements;

WHEREAS, the Parties desire to define the process and requirements for documenting certain of their respective maintenance and jurisdictional responsibilities associated with the EOWA Project and the OMP, as generally depicted on Exhibit I;
WHEREAS, the EOWA Project includes improvements to, in and around Touhy Avenue, specifically reconstruction and relocation ofthe south leg ofthe Mount Prospect Road and Touhy Avenue intersection and construction of a sidewalk and shared-use path within the City's municipal limits ("Touhy Avenue Improvements");

WHEREAS, the EOWA Project also includes relocation ofthe existing access road to the South ASR-9, as depicted on Exhibit J, which road will extend from Taft Avenue under I-490 northbound and southbound bridges and the Union Pacific Railroad ("UPRR') bridge over the CP Bensenville Yard and will be located on City, UPRR and Tollway property, each of which will require use ofthe road for access to the South ASR-9, the UPRR bridge and the I-490 bridge;
WHEREAS, the Parties agree that unless otherwise modified by this Addendum, the Agreement is still in effect;
WHEREAS, the Parties desire to enter into this Addendum, which is authorized by Article Vll, Section 10 ofthe Illinois Constitution and the Illinois Intergovernmental Cooperation Act, 5 ILCS 220/1, et seq.;
|1010|
WHEREAS, the Tollway, by virtue of its powers as set forth in the Illinois Toll Highway Act, 605 ILCS 10/1, et seq:., is authorized to enter into this Addendum;

In addition, Runway 9R/27L navigational aids will
|1010|
be constructed on Tollway NAVAID Property following the Tollway's transfer or grant of rights in that Property to the City. The City is responsible for updating the ALP as necessary to include I-490 and associated EOWA Project improvements.
No Conflict with Western Access (Added). The EOWA Project improvements at the WAI include local and IL 390 access to and from the Airport (i.e., 3-in, 3-out) and, as part of future phases of work, ramps connecting the Airport to and from 1-490 (i.e., 1-490 Ramps to/from Airport) as depicted on Exhibit H and described further in Section 25. As part of this Addendum, the City agrees to the proposed location and configuration ofthe WAI ramps and concurs that the configuration is compatible with the City's future development at the WLRA.
Negative Impacts (Replaced). The Parties understand that aside from acceptable Temporary Construction Impact and Temporary Runway 10R/28L Impact, the EOWA Project, the Touhy Avenue Improvements and the Lee Street Improvements will not cause Permanent Impacts on Airport operations after construction. Except for treatment of Runway 14R/32L, as provided in Subsection 5C of the Agreement, to the extent the FAA determines that the EOWA Project, the Touhy Avenue Improvements, the Lee Street Improvements, the conveyance of any City Transfer Property or Subsequently Identified Property may cause Permanent Impacts, the Tollway must cooperate with the City to alleviate such Permanent Impacts, including preparing design alternatives and revising the proposed City Transfer Property, in a manner sufficient to allow the EOWA Project, the Touhy Avenue Improvements and the Lee Street Improvements to proceed while eliminating Permanent Impacts on existing and planned Airport runway operations and facilities. As designed, the construction of the EOWA Project may result in Temporary Construction Impacts on Airport operations due to work associated with modification ofthe ALSF-2 systems for Runway 9L/27R, Runway 10C/28C and Runway 10L/28R. Prior to any temporary interference with aircraft or operations related to the Airport necessitated by construction for the EOWA Project, the Tollway must coordinate with the City on circumstances and obtain acknowledgement by FAA via written aeronautical determination. The Parties understand that a Temporary Runway 10R/28L Impact, as further contemplated in Section 23.A., may become necessary to enable construction of the Revised I-490 South Leg.
Section 4. APPROVAL OF PARCELS COMPRISING CITY TRANSFER PROPERTY; SUBSEQUENTLY IDENTIFIED PROPERTY
B. Approvals of Subseguentlv Identified Property
(1) (Replaced) The Tollway will request a conveyance and provide the City with draft conveyance documents for that parcel, including a legal description, a form of deed or easement, and if applicable the scope of easement rights.
(6) (Replaced) For any Subsequently Identified Property approved by the City within 36 months after the Addendum Effective Date, the compensation will be: (a) $12.50 per square foot of land area for a parcel transferred in fee simple or for a grant of a permanent easement (other than parcels within LUR#1); and (b) $0 for a grant of a temporary construction easement. For any Subsequently Identified Property approved by the City more than 36 months after the Addendum Effective Date, additional compensation, if any, will be determined by subsequent agreement ofthe Parties.
Section 5. COMPENSATION FOR PROPERTY TITLE AND RIGHTS
A. Compensation (Replaced). The Parties agree that the Tollway will pay the City $107,773,452, which consists of $19,529,604 for the parcels within LUR#1 (as defined below) and $88,243,848 for all remaining parcels not otherwise included within LUR#1 ("Compensation").
|1010|
The Parlies agree that the Compensation is the full and complete consideration for all transfers and grants of Fee Parcels, Permanent Easements and Temporary Construction Easements of the City Transfer Property.
B. Strict Joint Order Escrow Account; Disbursement of Compensation (Replaced). Compensation will be disbursed from the Tollway to the City at the real estate closing(s) of title or property rights in City Transfer Property. Closing funds will be disbursed to the City proportionately for the conveyance of City Transfer Property at the time of Closing based on the total square feet of land included in the Fee Parcels or Permanent Easement Parcels being conveyed at the Closing, except that the disbursement of Closing funds at the final Closing (i.e., the Closing at which the last City Transfer Property is conveyed to the Tollway) will be adjusted so that all, but not more than all, of the Compensation has been disbursed to the City. Closing funds will be disbursed to the City proportionately for each Closing by multiplying the "Unit Va/ue" as defined in this Subsection B by the total square feet of land included in the Fee Parcels or Permanent Easement Parcels being conveyed at the Closing. A Unit Value of $11 per square foot will be applied to the Fee Parcels and Permanent Easement Parcels included in LUR #1 (described below) that have a total land area of 1,775,418 square feet and have been approved for release by the FAA. As depicted in Exhibit A, the remaining Fee Parcels and Permanent Easement Parcels (excluding LUR #1) have a total land area of 7,059,508 square feet and a Unit Value of $12.50 per square foot will be applied to the total square feet of land included in these remaining parcels to be conveyed at the Closing(s) (excluding parcels within LUR#1).

The Parties agree to cooperate and diligently take necessary actions including, but not limited to, those specified in the Agreement and in this Addendum, as time is of the essence relative to the Tollway's construction of the EOWA Project.
Section 15. MANAGEMENT OF STOCKPILED SOIL
A. Stockpiled Soil Amounts (Added). Further, the City has identified additional Stockpiled Soil, generally located within the WLRA ("WLRA Soil), which is required to be removed in conjunction with plans for future development by the City within the same area.
E. Stockpiled Soil Retained by the City (Replaced). The City will retain on City-owned property not more than the total volume of Stockpiled Soil beyond that which can be accommodated within stockpile parcel locations 16 and 17, as shown on Exhibit A, and the area immediately adjacent to and south of stockpile parcel location 16 (shown on Exhibit A). The Tollway may design plans and specifications to maximize the volume of Stockpiled Soil to be retained in the aforesaid locations, and the City will reasonably cooperate with the Tollway to implement such design plans, including issuance of permits and related effort, provided that all design plans and specifications and the location of Stockpiled Soil in the aforementioned locations on City-owned property will be undertaken and maintained in accordance with laws and regulations, including without limitation FAA regulations. Except as otherwise specifically provided in the Agreement or this Addendum, all sorting, relocation, placement, grading and disposal, including without limitation disposal of Hazardous Material, of Stockpiled Soil in the above locations as shown on Exhibit A, which may be used for the EOWA Project or the Touhy Avenue Improvements, including WLRA Soil, will be at the Tollway's sole expense.
H. WLRA Soil (Added). In support of the proposed development within the WLRA, the City has prepared a preliminary concept pertaining to the reconfiguration ofthe site terrain in the WLRA areas generally depicted on Exhibit H1, including details regarding the use and/or disposition of existing WLRA Soil materials to be impacted, sorted, disposed of and/or relocated to meet the City's long-term developments. The concept details envision the use and/or disposition of these materials, depending on their general classification and quality, for the formation of embankments and/or structural use. To assist coordination with the Tollway concerning elements of the EOWA Project in and proximate to the WLRA, the City has prepared a series of conceptual design documents defining the goals and requirements for the material management, including performance criteria to be used in the execution ofthe WLRA Soil Project (collectively, "Concept Grading Plan"), which are discussed below and depicted in concept in Exhibit H1.
The Parties agree that the execution of the WLRA Soil Project is compatible with and

12

required for the City to proceed with future development at the WLRA. The City is solely responsible for work subsequent to the Tollway's completion ofthe WLRA Soil Project, including but not limited to, a circulation road (depicted on Exhibit H), parking facilities and other necessary improvements.
As part ofthe WLRA Soil Project, the Tollway will dispose of, sort and relocate WLRA Soil in accordance with the Concept Grading Plan. For WLRA Soil and materials to be disposed of, the Tollway must identify off-Airport disposal sites and shall bear the cost of sorting, relocating, placing, grading and disposal, including without limitation disposal of Hazardous Material. The City will issue all City permits, temporary construction easements or other approvals, at no expense to the Tollway, which may be necessary for the Tollway to undertake sorting and relocation of WLRA Soil in accordance with the Concept Grading Plan.
1. Representations & Assumptions. The City has provided a preliminary concept as Exhibit H1, which guides the overall assumptions forthe WLRA Soil Project, which includes:
a. Performance Criteria. The execution of the WLRA Soil Project (design and construction) will adhere to the overall goal of using on site materials, to the greatest extent possible, to build the City-designated lines and grades that will support the City's proposed future development ofthe WLRA. Sound engineering practice will be applied to determine the suitability and use of on site materials to ensure long-lasting and competent earthen foundations for the planned future improvements.
i. For general purposes, the materials expected to be found on site may be categorized within one of the following groups:
Unsuitable Material shall be any material determined to contain vegetable or organic matter, such as muck, peat, organic silt, topsoil or sod and will be considered not allowable to use in formation of embankments within the zone of structural influence ("Zone B"), which shall be defined as the 1:2 slope extending from the top outside edge of constructed embankment depicted on Exhibit H2. Such material, if capable of supporting vegetation, may be used in the top layers of embankment slopes.
Suitable Material shall be any uniform material which, based on its geotechnical characteristics, is deemed structurally fit to'be used for construction of subgrade and embankment areas for roadways or building footprints, as represented on Exhibit H2.
Restricted Material shall be any material other than Unsuitable Material and other than Suitable Material. Restricted Material may be used only in the construction of embankments in areas outside ofthe roadways or building footprints (see Exhibit H1) and in Zone B as depicted in Exhibit H2.
Refuse Material shall be any non-hazardous solid waste. This material is not permitted in the formation of embankments of any kind. This material must be collected and transported to a processing or solid waste disposal site.
Clean Construction or Demolition Debris ("CCDD"). As defined in 415 ILCS 5/3.160(b), as amended, CCDD shall include

13

uncontaminated broken concrete without protruding metal bars, bricks, rock, stone or reclaimed asphalt pavement generated from construction or demolition activities. The use of this material must be selective, used at appropriate depths, and processed so as to ensure firm and stable embankments.
To the extent practical and based on the technical properties of the materials, implementation ofthe WLRA Soil Project will prioritize the use of materials within the following framework.

For areas slated for buildings, roads and other surface improvements, the immediately underlying soils, as well as soils within the area of structural influence, must be capable of sustaining the proposed loads without experiencing unexpected or excessive settlement. The formation of embankments must be engineered to provide adequate and stable support and must be composed of Suitable Materials.
For areas not slated for buildings, roads and other surface improvements, Zone B embankments may be constructed with materials of lesser structural qualities, including Restricted Materials, CCDD or Unsuitable Material as provided above. These embankments must be restored and finished with a layer of topsoil capable of sustaining vegetation so as to prevent erosion. The use of these materials is permitted with the understanding that embankments must be engineered to be stable and maintain their lines and grades over time.
At the completion of the WLRA Soil Project, all areas must be restored in compliance with applicable regulatory requirements.
The Tollway must perform any and all site explorations necessary to determine the character and quantities ofthe Stockpiled Soil, as described in Section H.l.a.ii, and must develop an earthwork management strategy for the .use, processing, movement and disposal of Stockpiled Soil and materials on the WLRA site. This earthwork management strategy shall be one of the deliverables included in the early design milestones for the execution of the WLRA Soil Project and is subject to the City's review and approval, which shall not be unreasonably withheld.
Disposal. Characteristics of soil material requiring disposal are generally classified as Refuse Material, as described above. For purposes ofthe development ofthe Concept Grading Plan, it shall be assumed that Refuse Material represents 25%, by volume, of the WLRA Soil. If higher, the Parties will work together to revise the WLRA Soil Project, and the City shall develop two engineered alternatives that reduce the quantity of Refuse Material, as maximally as possible, that must be disposed of by the Tollway. The Tollway will review the engineered alternatives provided and determine, in its reasonable discretion, which alternative to proceed with as the basis for completing the WLRA Soil Project, and the City shall adjust the Concept Grading Plan, as necessary, to conform same to the Tollway's determination.
Limitations on Undercuts. Subject to the foregoing, in performing the WLRA Soil

14

Project, the Tollway will construct to elevations given in the Concept Grading Plan. To the extent that Unsuitable Material is encountered below the excavation elevation limits established by the Concept Grading Plan, the Tollway will explore options to stabilize the in-situ soils to achieve the required embankments and cuts.
d. Restriction on Import of Soil. To the extent that existing materials located within the WLRA are insufficient to construct, embankments to the lines and grades shown on the Concept Grading Plan, the City and Tollway will revise the Concept Grading Plan, maximizing elevations to the greatest extent possible using on site materials that meet the Performance Criteria. The Tollway shall not be required to acquire soil or other materials to complete the WLRA Soil Project. However, to the extent necessary to complete the WLRA Soil Project in accordance with the revised the Concept Grading Plan, the Tollway will import soil or other materials from other Airport property.
Engineering. The Tollway will be responsible for procuring/engaging engineering services to prepare design and construction documents for the WLRA Soil Project, which will provide for handing and disposition of WLRA Soil in accordance with this Addendum except that the City shall be obligated to sign any hazardous waste manifests required for the disposal of any WLRA Soils that are Hazardous Material. The Tollway will engage the City in the development of the design and construction documents and will request the City's review at set design milestones, including, but not limited to, 30%, 60%, 90% and Issue for Bid. The City may request reasonable changes to the design and construction documents pertaining to the handling and disposition of WLRA Soil. The Tollway will take reasonable steps to accommodate the City's requests. If the City provides comments to the Tollway, the Tollway will revise the design and construction plans, as the Tollway determines necessary or appropriate, and submit revised plans, if any, to the City for further review. After receiving any revised plans, if the City has further comments, the City and the Tollway will promptly meet to discuss and resolve all matters related to the revised plans to the best of their ability. The Tollway will be responsible for documenting and reconciling, to the extent deemed necessary or appropriate, all comments received from the City.
Utilities. The Parties agree that the WLRA Soil Project will avoid disturbance or impact to Airport utilities, including those previously relocated as part ofthe Central De-Icing Facility Improvements. Should conflicts be identified that cannot be changed due to the City's Concept Grading Plan and intent, the Parties agree to work together to revise the WLRA Soil Project to avoid the need to relocate the utilities. In the event relocation cannot be avoided, the City agrees to be responsible for the costs of the associated relocation or modification.
NEPA Documentation. The City will perform all required environmental studies and develop any ofthe NEPA documentation that may be necessary to support its long-term development vision for the WLRA. The City will coordinate directly with the FAA to ensure all environmental approvals are in place prior to the Tollway undertaking construction.
Stormwater. As part of the WLRA Soil Project, the Tollway will design and construct two detention basins in accordance with the Concept Grading Plan, as depicted on Exhibit H. The City will prepare, facilitate and obtain any stormwater permits required for the WLRA Soil Project from the IEPA, IDNR, USACE, DuPage County and other resource agencies. The Tollway will provide reasonable support relating to development of exhibits and plans to support development of permitting materials.

15

Phased Implementation: The Tollway intends to perform the WLRA Soil Project construction in two or more phases tied to the progress of the 1-490 corridor. The first phase of the WLRA Soil project is contemplated to include construction of approximately half of the work shown on the Concept Grading Plan. The Tollway will advertise for the first phase of the WLRA Soil Project after the City and Tollway close on the City Transfer Property parcels associated with Land Use Release #2 and #3 and the City authorizes the Tollway to start work relative to Runway 10L/28R and Runway 10C/28C ALSF-2 systems. The second phase of the WLRA Soil Project will commence no earlier than 2025 and will be dependent on the establishment of a defined timeline for the development of future public access to the Airport.
Land Rights. Prior to the commencement of any construction, the City must grant the Tollway any and all necessary land rights for the WLRA Soil Project at no cost to the Tollway. Said land rights must include, but shall not be limited to, necessary land sites, associated access roads and/or utility routes required to implement the WLRA Soil project.
Environmental. Except as set forth below, the Tollway is responsible for remediating Hazardous Material consistent with the Concept Grading Plan. Any potential remediation is dependent on contamination type and will be limited to the level required by applicable federal and state regulations.

While the Tollway is responsible for the costs of constructing the WLRA Soil Project, the City shall be deemed the generator of WLRA Soil that is Hazardous Material or solid waste and Refuse Material that requires disposal off site. If a signature as "generator" is required on waste manifests, waste profile sheets or generator's certifications of non-special waste, the Tollway or its agent shall be authorized to sign such documents as generator on behalf ofthe City.
The City shall identify any known existing releases or records of Hazardous Material limited to/as defined by the level required by applicable federal and state regulations and provide such information to the Tollway during the design of the WLRA Soil Project.
In connection with development projects at the WLRA after the Tollway completes the WLRA Soil Project, the City shall be responsible for remediating Hazardous Material found on the WLRA site below the elevations required to construct the WLRA Soil Project or groundwater that infiltrates the elevations required to construct the WLRA Soil Project, and not otherwise related to the Tollway's activities.
The City also agrees to save, defend and hold the Tollway harmless for and against any and all costs (including reasonable attorneys' fees), liabilities and or claims by third parties that arise out of hazardous materials or contamination found on the WLRA site in the future that are not directly attributable to the WLRA Soil Project or the EOWA Project.

As necessary for implementation of the EOWA Project and to ensure timeliness of its implementation, the Tollway agrees to reimburse the City for certain associated costs that are incurred by the City. The Tollway has paid the City per Section 15.C(2) of the Agreement. As of the Addendum Effective Date, the Tollway has paid the City for certain scopes of earthwork (Section 15 of Agreement), AOA Perimeter Fence and Road Relocation (Section 12 of Agreement) and initial City-appointed liaison costs (Section 15.G. of Agreement). Additional costs to be incurred by the City and reimbursed by the Tollway as part of ongoing or future work include utility relocations (Section 13.B. of Agreement), Runway 9R and 9C ALSF-2 work necessary to accommodate future EOWA Project construction on City Transfer Property (Section 13.A. of Agreement), additional City-appointed liaison costs (Section 15.G. of Agreement), and other professional services and/or consultants the Parties deem necessary to support the EOWA Project and WLRA Soil Project. Since execution ofthe Agreement, no specific work subject to reimbursement has been identified. Additional Tollway funds of $5,000,000 are authorized to be paid to the City pursuant to and in accordance with this Section. The City agrees to report quarterly, or on other reasonable intervals as agreed to by the Parties, regarding the status of amounts spent and/or committed and will notify the Tollway when the total amount spent and/or committed reaches $4,000,000, at which time the Parties agree to evaluate the need for additional funding, if any, for continuing reimbursement of such costs in accordance with this Section. Any proposed expenditures within the $5,000,000 limit set forth above will be authorized on an as needed basis by the Designated Representatives and reimbursed based on actual costs (described in Section 26.A).
For future requests by the City that the Tollway perform supplemental work for the City's benefit, which work is not otherwise planned by the Tollway as part ofthe EOWA Project, the WLRA Soil Project, or other matters contemplated as ofthe Addendum Effective Date, the Tollway agrees to add said supplemental work to Tollway construction contract(s), if possible and provided that said work will not unreasonably delay the EOWA Project, as solely determined by the Tollway. The City shall be responsible for the costs of any such supplemental work, and the Parties agree that such costs may be deducted from costs of Tollway reimbursable work as described above. All costs shall be based upon actual final costs.

Section 22. Revised I-490 South Leg (Added)
A. Location to Airport. The Revised I-490 South Leg proposed by the Tollway as part of the EOWA Project is adjacent to Runway 10R/28L and associated operational features including, without limitation, the Runway Safety Area ("RSA"); the Runway Object-Free Area ("ROFA"); the Runway Protection Zone {"RPZ'); the Instrument Landing System (i.e., ILS), comprised of the Glideslope and Localizer Antennae Arrays and associated critical areas; and the ALSF-2 system as depicted on Exhibit N. The Parties understand and acknowledge that the

18

current capability, location and operational circumstance of Runway 10R/28L, as ofthe date of this Addendum, including without limitation all operational features and systems serving runway operations, shall be considered as a baseline condition from which any change in capability, location or operational circumstance, including without limitation any Permanent Impact, will be determined.
B. Conditions. The Tollway agrees to advance the Revised I-490 South Leg as
follows:
The Tollway will configure and construct the Revised I-490 South Leg so as to limit Temporary Construction Impacts to minimum durations as further indicated in Section 22.D and will not cause Permanent Impacts on Runway 10R/28L operations.
The Tollway agrees to perform necessary airfield aviation analyses and technical studies in conjunction with the Revised I-490 South Leg design to determine any change in capability, location or operational circumstance, including without limitation any Permanent Impact of the proposed roadway improvements on Airport operations, including any such reasonable analyses or studies as may be recommended by the City or required by the FAA. The aviation analyses and technical studies will include, but will not be limited to, Runway 10R/28L feasibility studies and ILS system modeling described further in Section 22.C(1).
The Tollway will sequence construction of the Revised I-490 South Leg in phases such that the Category I, Category II and Category III ("CAT I/I I/I IT) classification of Runway 10R/28L operations is restored at the end ofthe Revised I-490 South Leg construction.
The Tollway and City have developed the attached I-490 Project Overview Workplan ("Workplan") depicted on Exhibit O forthe purpose of managing design, construction, scheduling and other activities for the implementation of the EOWA Project. The City shall collaborate and reasonably respond to the Tollway's requests for review and/or approval of Workplan activities, including but not limited to, construction schedule and milestones or other activities that require City input, within 21 days of a request, unless otherwise agreed to between the Designated Individuals described in Section 26.A. Neither the City's provision of comments nor its failure to provide comments in relation to the Workplan shall be viewed as sanctioning or otherwise approving matters within the jurisdiction of the FAA, which include without limitation, impacts on airfield and runway operations; surrounding navigable airspace and protected surfaces as defined in 14 C.F.R. Part 77 and by the FAA; or any runway classification, instrument rating, or other utility or capability of any runway.
C. Design. The Tollway will implement the design and construction of the Revised
I-490 South Leg through several construction contracts as depicted on Exhibit L. The Tollway will
perform aviation analyses and technical studies as part of its design, including Runway 10R/28L
7460 studies and ILS system modeling. The design considerations are further described as
follows:
(1) Design Variants. The Tollway has proposed to design and construct the Revised I-490 South Leg as an open roadway corridor ("Revised 1-490 South Leg Design Variant') as detailed in the Tollway's South 1-490 Master Plan (December 2019) and depicted in Exhibit N. For purposes of comparing and evaluating the effect on

19

Runway 10R/28L ILS performance, and as requested by the City, the Tollway also will develop an adjusted Revised I-490 South Leg Design Variant that includes covering the l-490/lllinois Route 19 roadway corridor or portions thereof ("Alternate Design Variant) as depicted in Exhibit N1.
Aviation Analyses. Airspace feasibility studies will be submitted to the FAA through the industry standard Obstruction Evaluation/Airport Airspace Analysis ("OE/AAA") process including FAA 7460-1 Notice of Proposed Construction. The ILS system mathematical modeling will be performed to predict the effects on ILS (the glideslope and localizer antennae) signal performance and will be subject to review by the FAA. The Tollway will ensure ILS analysis will be conducted using industry standard software and available models, including Ohio University Glide Slope ("OUGS") software used to evaluate terrain and Ohio University NAVAID Performance Prediction Model ("OUNPPM") software used to evaluate reflections from objects. The Parties understand and acknowledge that the results of the foregoing modeling may be used in evaluating predictive analysis of performance of navigational aid equipment and that the results are empirical and may differ from actual conditions, which may be confirmed only by field tests and/or flight checks.
Determination of South I-490 Design Variant for Implementation. The Tollway will complete aviation analyses and technical studies for both the Revised I-490 South Leg Design Variant and the Alternate Design Variant in accordance with industry standards. Through preliminary design, variants will be evaluated based on a variety of criteria, including but not limited to: Runway 10R operational impacts during construction, and on ILS signal tolerance, relative to the ability to maintain CAT l/ll/lll operations as determined under FAA requirements after completion of EOWA Project construction; adherence to applicable roadway design criteria and governing policies, construction duration, construction cost as well as traffic operations during and after construction. Results and recommendations are subject to further review and endorsement by the FAA, FHWA and IDOT. The Parties understand and acknowledge that the FAA Technical Operations service unit is tasked with ensuring safety and efficiency in the National Airspace System ("NAS") by effectively managing air navigation services and infrastructure, including oversight ofthe following activities and services:
efficient flight services to customers through responsive and cost-effective maintenance of NAS facilities, systems and equipment;
safe, cost-effective, and efficient communications; frequency spectrum engineering; and navigational services for NAS;
standard development, evaluation and certification of NAS procedures and equipment for customers worldwide; and
infrastructure management including policy, programming, requirements, engineering, integration and implementation support, service life extension, and maintenance support.
Based on the aviation analyses, and subject to review by the FAA, the Parties understand and acknowledge that the Tollway's determination of the South I-490 Design Variant for implementation shall be predicated upon the following:
• Should the aviation analyses and technical studies for the Revised

20

1-490 South Leg Design Variant predict no Permanent Impact to Runway 10R/28L capability, location and operational circumstance, the Tollway will implement the Revised I-490 South Leg Design Variant, except as set forth below.
Should analyses and technical studies for the Alternate Design Variant similarly predict no Permanent Impact to Runway 10R/28L capability, location and operational circumstance the Tollway, in its sole discretion, may implement either the Revised I-490 South Leg Design Variant or the Alternate Design Variant.
Should the analyses and technical studies for the Revised I-490 South Leg Design Variant predict a Permanent Impact to Runway 10R/28L capability, location and operational circumstance, the Tollway will implement the Alternate Design Variant if the Alternate Design Variant produces acceptable evaluation results including prediction of no Permanent Impact to Runway 10R/28L capability, location and operational circumstance.
Should the analyses and technical studies for the Revised I-490 South Leg Design Variant and the Alternate Design Variant both predict a Permanent Impact to Runway 10R/28L capability, location and operational circumstance, the Tollway will work to develop a second alternate for the Revised I-490 South Leg that will mitigate any Permanent Impact to Runway 10R/28L capability, location and operational circumstance. In such event, development of any revised and/or second alternate plan for the Revised I-490 South Leg (other than the Revised I-490 South Leg Design Variant or the Alternate Design Variant) shall consider necessary NEPA actions required, if any, as well as aviation analyses as aforesaid, to ensure said design variant produces acceptable evaluation results including prediction for no Permanent Impact to Runway 10R/28L capability, location and operational circumstance, prior to Tollway implementing said design variant.
While the City will reasonably cooperate with the Tollway with respect to the Tollway's performance of the foregoing analyses and studies, neither the City's participation or provision of comments, nor its failure to provide comments shall be viewed as sanctioning or otherwise approving matters within the jurisdiction of the FAA, which include without limitation, impacts on airfield and runway operations; surrounding navigable airspace and protected surfaces as defined in 14 C.F.R. Part 77 and by the FAA; or any runway classification, instrument rating, or other utility or capability of any runway.

Notwithstanding the foregoing, the Parties acknowledge that the Tollway's plans for construction ofthe Revised I-490 South Leg may necessitate Temporary Runway 10R/28L Impact (including without limitation potential ILS and ALSF-2 system outages and/or runway closure(s)) to perform work within the existing AOA, affecting the navigable airspace of Runway 10R/28L, and/or modification of Runway 10R/28L's visual and electronic navigational aids.
(1) Coordination. During construction implementation of the Revised South I-490 South Leg, the City and the Tollway shall continue to convene aviation technical working group meetings at appropriate intervals to review and coordinate construction activities to, in part, assess and address potential Temporary Construction Impact. The Tollway will provide information on its planned and/or preferred construction activity and facilitate collaborative review of the subject matter in relation to any perceived or potential review of impact on Airport and runway operations. The Parties will work collaboratively to identify reasonable solutions for planned construction activity to mitigate and/or minimize ILS outages, including runway closures. In the event the Parties acknowledge that construction cannot reasonably proceed without a reasonably foreseeable ILS outage and/or runway closure, the Parties agree to work with the FAA to confirm a process and procedure to mitigate impacts of such circumstance as well as identify appropriate
22

procedures for returning the impacted ILS or runway operation back to service at pre-construction conditions. The Parties further agree to promptly take necessary actions or complete work as required and discussed in such meetings.
Field Verification and Flight Checks: During construction implementation of the Revised 1-490 South Leg, the Tollway shall request that FAA perform flight checks at certain milestone intervals to identify any Permanent Impact to Runway 10R/28L, which intervals shall be reasonably determined by the Tollway and the City. In the event the FAA is unavailable or unwilling to complete such flight checks at the requested intervals, the Tollway shall employ such other efforts as may be necessary to complete flight checks at such intervals, to identify any Permanent Impact to Runway 10R/28L. If a Permanent Impact is detected or reasonably foreseen as a result of flight check data or other means, the Tollway immediately will take corrective action(s) as necessary to mitigate and eliminate the Permanent Impact or foreseeable Permanent Impact, including without limitation, modifying design, removing material or equipment installed, or taking other measures as may be reasonably necessary to allow construction to proceed without perpetuating or exacerbating any Permanent Impact or foreseeable Permanent Impact. The Tollway will continue construction after confirming the absence of Permanent Impact or foreseeable Permanent Impact to Runway 10R/28L.
Stakeholder Notice. The City agrees to notify Airport Stakeholders, as promptly as possible, and to coordinate with Airport Stakeholders to accommodate the Temporary Runway 10R/28L Impacts as required to construct the EOWA Project. Temporary Runway 10R/28L Impacts are anticipated to occur in years 2024 through 2025 (in the event of implementation ofthe Alternate Design Variant, 2026 as well) or as otherwise agreed in writing. The Parties will work collaboratively to ensure construction resulting in Temporary Construction Impact, including without limitation any ILS and ALSF-2 outages or closure of Runway 10R/28L, is minimized.
Restoring Operating Conditions. Following completion of construction of the South I-490 Design Variant, failure to promptly restore Runway 10R/28L capability, location and operational circumstance will result in damages defined in Section 23.D.

Access. The Revised I-490 South Leg requires modification of South Cargo Road at its intersection with Illinois Route 19, as depicted on Exhibit N. The Tollway agrees to maintain access to South Cargo Road during construction or to coordinate any limited temporary closures with the City prior to implementation.
Restoration. Upon completing the EOWA Project, the Tollway shall, as its expense, undertake to restore Airport property temporarily impacted by the EOWA Project to the condition in which it existed prior to the EOWA Project.
Section 23. Airport Operations (Added)
A. ALSF-2 Modifications. Construction of I-490 along the west side of the Airport requires Temporary Construction Impact to modify three ALSF-2 systems, specifically, Runways 10L/28R, 10C/28C and 9L/27R. The Parties agree that modifications will occur on only one runway per construction season (i.e., which generally is between May and November), unless the Parties agree otherwise in writing. Prior to commencing modification work, the Parties shall agree on a reasonable construction schedule for the modifications to each runway ALSF-2 system,

23

including without limitation scheduling for any implicated night construction in an active Runway Safety Area or Taxiway Object Free Area. The Tollway's construction of 1-490 and the City's request for the FAA's approval of modification of each runway ALSF-2 system shall proceed in a diligent manner consistent with the terms of this Addendum. Unless otherwise approved by the Parties, the Tollway will sequence EOWA Project construction affecting runway ALSF-2 systems as shown on Exhibit L and as follows or as otherwise agreed:
Runway 10L/28R ALSF-2 Temporary Construction Impact to occur in 2022;
Runway 10C/28C ALSF-2 Temporary Construction Impact to occur in 2023; and
Runway 9L/27R ALSF-2 Temporary Construction Impact to occur in 2025.
The Parties agree that Temporary Construction Impact to modify ALSF-2 systems will occur within a specified timeframe coordinated with and agreed to by the City, in advance, during design of contract(s) involving such work. While modification work is being performed, the ALSF-2 system will be fully removed from service. The Tollway will perform modification work in accordance with the 7460-determination issued by the FAA, which may include additional temporary ILS or airfield restrictions. Following the Temporary Construction Impact on the runways listed above, modification to Runway 10R's ALSF-2 system will occur as part of the construction process defined in Section 22.D.
The City agrees to notify and coordinate with Airport Stakeholders, as required and determined by the City, to support the Tollway's construction schedule and allow the required ALSF-2 system modifications. The Tollway will provide information for, or participate in, such coordination at the request of the City and as necessary.

South ASR-9. The City agrees to enter into a separate "CDA Reciprocal Access Easement Agreement" with UPRR, in the form attached as Exhibit P, that will provide the City and its assigns access to the South ASR-9 facility across UPRR property and provide UPRR access to its facilities across City property, over the locations generally depicted on Exhibit J (denoted thereon as Permanent Easements "UPRR to City" and "City to UPRR"). The Tollway will facilitate execution ofthe CDA Reciprocal Access Easement Agreement between the City and the UPRR. This Addendum hereby authorizes the CDA Commissioner to execute said agreement.
The Tollway agrees to grant the City access to the South ASR-9 facility across the portion of the access road located on Tollway property. The Tollway also agrees to install new electrical and communication feeders from South ASR-9 to the south side ofthe airfield, as depicted on Exhibit J.
Liguidated Damages for Failure to Restore Runway Operations:
As part of the sequenced construction implementation of the I-490 Tollway, in the event any Temporary Construction Impact exceeds the agreed upon duration for construction, due to actions or inaction of the Tollway or a Tollway contractor, including without limitation the Temporary Construction Impact to Runways 9L/27R, 10C/28C and 10L/28R described in Section 23.A or the Temporary Runway 10R/28L Impact described in Section 22.D, and if the Tollway does not or cannot identify and undertake appropriate corrective action to restore runway operations within a reasonable period, the Tollway will be responsible for damages as defined below.


24

Except with respect to active Runway Safety Areas and Taxiway Object Free Areas, in the event the Tollway fails to mitigate or discontinue any Temporary Construction Impact that exceeds the agreed upon duration for construction, including without limitation the Temporary Construction Impact to Runways 9L/27R, 10C/28C and 10L/28R described in Section 23A or the Temporary Runway 10R/28L Impact described in Section 22.D, the Tollway will be responsible for liquidated damages, which shall be assessed as follows:

MILESTONE AMOUNT OF LIQUIDATED DAMAGES
Milestone 1 (TBD -based upon specific contract and construction activity) $10,000 per calendar day
Milestone 2 (TBD -based upon specific contract and construction activity) $15,000 per calendar day

The Parties agree that Milestone dates will be determined through Tollway and City coordination during Construction Document production for individual Contracts. The Parties further agree that pursuant to Tollway contract special provisions, Liquidated Damages will be assessed against Tollway contractors.

The last day counted will be the day on which the unacceptable Temporary Construction Impact or Temporary Runway 10R/28L Impact shall have abated and/or become mitigated with associated runway capabilities and operations restored and the FAA shall have approved such abatement and restoration of runway operations.

NOTE: Night construction in an active Runway Safety Area or Taxiway Object Free Area may be performed between the hours of 10:00 PM and 6:00 AM unless noted otherwise and approved by the CDA Commissioner. Notwithstanding the foregoing, failure to restore active Runway Safety Areas and Taxiway Object Free Areas to full operational capability by 6:00 AM will result in the assessment of Liquidated Damages as follows:

Runway Safety Areas
$10,000.00 for the first 15 minutes (or increments of) beyond 6:00 AM. $5,000.00 for every 15 minutes (or increments of) thereafter.

Taxiway Object Free Areas
$5,000.00 forthe first 15 minutes (or increments of) beyond 6:00 AM. $2,500.00 for every 15 minutes (or increments of) thereafter.

Relative to active Runway Safety Areas and Taxiway Object Free Areas, the official time for which damages will accrue will be determined by the CDA Commissioner, who shall reasonably consider input from the Tollway.

www.illinoistollway.com

The Illinois Tollway and City of Chicago are party to a separate Intergovernmental Agreement executed April 24, 2017 (the "EOWA IGA"), that defines their respective responsibilities for the EOWA Project, including but not limited to, with respect to the relocation ofthe existing CPD K-9 Training Facility.

As part of the EOWA improvements, the County of Cook, in partnership with the Illinois Tollway, will complete the design and construction of improvements along Touhy Avenue between Elmhurst Road and Mount Prospect Road included in Contract IN02 (the "Touhy Avenue Project"). The Touhy Avenue Project includes construction of a new quadrant bypass connector roadway from Old Higgins Road to Touhy Avenue, realignment and reconstruction of the Touhy Avenue and Mount Prospect Road intersection, the construction of a new bridge to carry Touhy Avenue over the future Western Access toll highway, and the construction of a new bridge to carry Touhy Avenue over the Union Pacific Railroad (UPRR). The Touhy Avenue Project also includes the installation of drainage improvements, pavement markings, signing, roadway lighting, multi-use paths, sidewalk, traffic signals, emergency vehicle pre-emption, landscaping, and all other work necessary to complete the improvements in accordance with the approved construction plans and specifications.

The CPD operates the K-9 Training Facility located at 320 West Touhy Avenue in Des Plaines, Illinois (the "K-9 Facility") on CDA property (see Exhibit A).

The Touhy Avenue Project and EOWA Project improvements impact the K-9 Facility and require it to be relocated. The Illinois Tollway provided a "Notice of Relocation Eligibility and 90-Day Notice" letter to CPD on May 24, 2017 that provided notification ofthe required relocation ofthe K-9 Facility.

The Touhy Avenue Project includes the construction of a temporary bypass road along Touhy Avenue that provides access to the K-9 Facility during construction ofthe Touhy Avenue Project (see Exhibit A).

The Touhy Avenue Project improvements include the construction of new storm sewer that impacts the existing explosive site chamber located on the CDA property on which the K-9 Facility is located.

The relocated K-9 Facility will maintain the features of the existing site, including a building facility, fenced training area accommodations, an explosive site chamber and parking (the "Relocated K-9 Facility").

The Relocated K-9 Facility building facility will include space for dog kennels, offices, bathrooms, laundry, storage, detection rooms, and other areas required for the dog and

RECIPROCAL ACCESS EASEMENT AGREEMENT

This RECIPROCAL ACCESS EASEMENT AGREEMENT ("Agreement") is made
this day of , 202_, by and between UNION PACIFIC
RAILROAD COMPANY, a Delaware corporation ("UPRR"), and CHICAGO DEPARTMENT
OF AVIATION, a ("CDA"). UPRR and CDA are sometimes collectively
referred to herein as the "Parties", and sometime individually as a "Party".

RECITALS:

A. UPRR operates a railroad on certain real property located in County, State
of Illinois, legally described in Exhibit A, attached hereto and made a part hereof ("UPRR Property").
CDA owns fee title to real property legally described in Exhibit B, attached hereto and made a part hereof ("CDA Property"), which is adjacent to the UPRR Property.
UPRR and CDA each desire to grant to the other, and their respective successors, assigns, agents, tenants, subtenants, and invitees (collectively, "Permittees"), a non-exclusive, perpetual easement for their common benefit for pedestrian and vehicular access, ingress, egress, and travel over and upon that certain access roadway located over that portion of the UPRR Property legally described in Exhibit C ("Easement Area I"), and that portion of the CDA Property legally described in Exhibit D ("Easement Area II"), each of which are attached hereto and made a part hereof (Easement Area I and Easement Area II are sometime collectively referred to herein as the "Roadway").

AGREEMENT:

NOW, THEREFORE, in consideration of the above recitals, the Parties agree as follows.

1. Grant of Reciprocal Access Easement. UPRR hereby grants to CDA, for itself and for use by its Permittees, a non-exclusive, perpetual easement for pedestrian and vehicular access, ingress, egress, and travel over Easement Area I ("Reciprocal Access Easement I"). CDA hereby

grants to UPRR, for itself and for use by its Permittees, a non-exclusive, perpetual easement for pedestrian and vehicular access, ingress, egress, and travel over Easement Area II ("Reciprocal Access Easement II"). Reciprocal Access Easement I and Reciprocal Access Easement II are sometimes collectively referred to in this Agreement as the "Reciprocal Access Easement".
No Impediments. UPRR and CDA, and their respective Permittees, covenant and agree not to construct any wall, barrier, building, fence, or other impediment at any time within the Reciprocal Access Easement which would hinder or impede the use of the Reciprocal Access Easement as provided herein.
Roadway Maintenance. UPRR and CDA shall each be responsible for maintaining and repairing that portion of the Roadway located on their respective properties at all times in a good, safe, and passable condition.
Not a Grant of a Superior Right. Nothing contained in this Agreement shall be deemed to convey to either Party, or their Permittees, a right to use the Reciprocal Access Easement that is superior to that of the other Party. UPRR and CDA acknowledge that the Reciprocal Access Easement is for their common benefit and the common benefit of their respective Permittees. UPRR and CDA each retain any and all rights not specifically granted herein, including, without limitation, (a) any and all rights which are not directly incompatible with the easements granted herein, and (b) the right to grant easements to other third parties over, under and through Easement Area I and Easement Area II, respectively, for any purpose that does not create unreasonable interference with the easements granted herein, including rights of way for similar use and utility easements. Each Party covenants to act reasonably so as to minimize any interference with the other's use of the Reciprocal Access Easement. Notwithstanding the foregoing, each Party acknowledges that from time to time such use and/or the ingress to or egress from the other's property by way of the Reciprocal Access Easement may be interrupted as a result of construction, reconstruction, maintenance or repair by the other to its property. Any such construction, reconstruction, maintenance or repair work shall be performed as expeditiously as is reasonably practicable under the circumstances and in a manner that minimizes disruption to the normal use of the Reciprocal Access Easement. Subject to the foregoing, and provided either that such interruption does not unreasonably interfere with a Party's use of the Reciprocal Access Easement, or that alternative temporary access is available, each Party expressly consents to such interruption and acknowledges that the other Party, or its Permittees, shall in no event be liable to it or its Permittees as a result of such interruption.
Existing Rights.

(a) The Reciprocal Access Easement is granted by each Party subject to all outstanding leases, licenses and other outstanding rights, including, without limitation, those for pipe, telephone, electric and fiber optic lines and the right of renewals and extensions of the same, and subject also to all conditions, limitations, restrictions, encumbrances, reservations or interests of any person that may affect Reciprocal Access Easement, whether recorded or unrecorded.

(b) The Reciprocal Access Easement is also limited to such rights as the applicable grantor Party may have in the applicable portion of the Roadway and is granted without warranty, express or implied. No damages shall be recoverable by either Party because of any dispossession or because of failure of, or defect in, a Party's title to the Roadway.

6. Not a Public Dedication. Nothing contained in this Agreement shall be deemed to be
a gift or dedication of any portion of Easement Area I or Easement Area II to the general public or
for the general public or for any public purpose whatsoever, and this Agreement shall be strictly
limited to and for the purposes expressed herein.

7. Recordation of Agreement. This Agreement shall be recorded in the Office of the
County Clerk/Recorder of County, Illinois, and shall serve as notice to all parties
succeeding to the interest of the Parties that their use of such property shall be benefitted and/or restricted in the manner herein described.
