APPROVED AS FORM: G7/ eputy i y tt e ° ate P:1Law111807p.doc Amended EXHIBIT 3 SITE PREPARATION PRELIMINARY PLAN The City will excavate the site to a uniform depth, installing an 18" sand and crushed limestone wearing surface and dewatering layer to the Final Design Subgrade Level utilizing the methods and techniques described in the Project Site soils report prepared by Terracon, dated November 15, 2000, attached as Exhibit A, and incorporated by this reference and subsequently detailed in the Office Tower's final design. The City will install a temporary dewatering system in the 18" layer (6" perforated pipe every 100' on center in both directions and two sump pits at opposite diagonal corners). The City will excavate the site such that the banks of the excavation along the entire periphery of the site will be left at a 45 degree slope down from the street curb line with well compacted cohesive earth and completely covered with staked in place heavy duty plastic sheeting. The developer will install the Office Tower's permanent underdrain system in the granular fill as discussed in the Terracon report and subsequently detailed in the project's final design. The intent of the above is to bring the site to a stable construction-ready condition enabling the Office Tower's contractor, upon City's completion of the above work, to occupy the site and begin foundation work upon a completely excavated and stabilized site. Before proceeding with work described above, the City will prepare, and gain Union Pacific's and the developer's approval of, Final Site Preparation Plan, which will incorporate both this intent, and the work described above. The design drawings and specifications necessary for the installation of the temporary dewatering system and 18" wearing and temporary drainage layer, the 45 degree slopes of the excavation, and excavation to the Final Design Subgrade elevation as required by Exhibit A (the "Design Documents") will be prepared and provided to the City by professional civil engineering and geotechnical consultants (the "Consultants") engaged on behalf of Union Pacific. The Design Documents prepared by the Consultants will be forwarded to the City for incorporation by the City into the bidding and procurement specifications and drawings for all of the work necessary to complete its obligations required by this Agreement (the "Contract Documents") upon which Union Pacific will have right of final review and approval prior to issuance for bid. The City will assemble and issue the Contract Documents for bid to contractors. Once the City has selected and entered into a contract with the contractor who will perform the work (the "Contractor") and the Contractor has begun work, the Consultants, on an as-needed basis, will advise the City rendering technical assistance and advice as to the Contractor's progress and adherence to the requirements of the Design Documents as contained in the Contract Documents. The City will cause the Contractor to execute the work as required by the Contract Documents and as modified by the Consultants' field observations and directions during the progress of the work. The City will remain responsible for bringing the site to a stable construction-ready condition as described above and in the Contract Documents and delivering the site to the developer's contractor. EXHIBIT A TO EXHIBIT 3 Drained Granular Base Recommendations We understand that the City of Omaha will remove all components from prior construction on the site down to the natural, lean clay subgrade soils. Relative to the currently estimated design subgrade elevation, it is anticipated that this may require additional cut in the southwest corner of the site, and fill in the northeast corner. Relatively wet, soft, and disturbance-sensitive lean clay soils are anticipated to be encountered, over most of the site, below the foundations and floor slabs of the prior construction. These soils are expected to be unstable under the loads of most conventional construction equipment. The natural lean clays that may presently be somewhat drier and more stable in the higher areas of the site will also be susceptible to softening and degradation of stability upon wetting and/or exposure to freeze/thaw cycles. For these reasons, it would be beneficial to combine excavation to design subgrade elevation with the demolition phase work to permit the necessary grading of the sensitive soils to be performed remotely with a hoe-type excavator supported on the existing rubble fill, as removals proceed across the site. This would also permit timely placement of a protective base to reduce subsequent deterioration of the exposed subgrade soils. In summary, the site demolition program should be coordinated with subsequent construction plans to the extent required to protect the subgrade soils against excessive disturbance during, or degradation following, the site demolition phase of work. This is recommended to avoid added costs or delays that could otherwise be incurred. In order to provide a stable base for construction equipment and subsequent floor slab support, it is recommended that soil over-excavation and replacement with granular material be performed. The following recommendations have been developed with the intent that the granular base survive construction to be incorporated in the permanent granular drainage systems below the planned building. It is recommended that the soils be over-excavated to a minimum depth of 18-inches below the proposed bottom of floor slab elevation in the building area. Where over- excavation from demolition extends only nominally deeper than this minimum depth, those areas could be backfilled with the sand/gravel base material described below. In areas where a significant thickness of new fill is required, granular material could be used as necessary to bridge soft subgrade soils for support of cohesive fill placement. Excavation in areas of disturbance sensitive subgrade soils should be performed remotely with a large, hoe-type excavator. The hoe bucket should be equipped with wide spade teeth. The soil should be excavated in thin horizontal lifts in a manner that avoids subgrade disturbance due to soil suction that can be created under the bucket. Prior to placement of the granular base, permanent drainage pipes should be installed in the over- excavated subgrades, as discussed below for the permanent drainage system. Consideration should be given to providing a longitudinal crown or swale in the soil subgrade to promote drainage toward the permanent drain lines. However, the recommended minimum thicknesses of granular material should be preserved. Clean, well-graded, sand and gravel meeting State of Nebraska Department of Roads specifications for 47B "fine aggregate for concrete" should be drifted head in an initial lift at least ten inches thick onto the over-excavated subgrade. The sand should be drifted ahead with a wide-track dozer sized to avoid disturbance of the underlying clays and compacted with a large vibratory plate or moderate sized vibratory smooth steel drum self-propelled roller. A minimum eight-inch thickness of 1%-inch minus crusher run limestone, or crushed concrete, containing less than ten percent material passing the No. 200 sieve should then be drifted ahead onto the sand/gravel base and compacted. The granular base materials should be compacted to at least 65 percent relative density in accordance with ASTM D-4253 and 4254. The soil over-excavation and granular base placement should extend at least several feet outside the perimeter of the building structure. Silt-fencing or grading in the form of ditches or sumps should also be provided around the perimeter of the granular base to divert surface run-off and silt from entering into the completed base area. Provisions should also be made to achieve control and prompt removal of surface water that collects in the excavation. Use of geotextile or geogrid is not recommended below the granular base stabilization layers or drainage materials due to the potential interference with foundation and utility installation. Care should be taken to avoid excessive fouling of the granular base materials with spoils from excavations or dirt carried in by construction equipment. A thin layer of common fill sand should be spread two to three inches thick over the crushed rock to reduce infiltration of soil, drilling slurry, concrete or other fines into the rock during construction. Care should be taken not to penetrate significantly into the crushed stone during spoils removal. The resulting surfaces are generally expected to be capable of supporting limited repetitions of construction equipment reasonably limited in ground contact pressure. However, excessively heavy or concentrated loads or numerous repetitions of moderately heavy loads could cause failure and should be avoided. Alternatively, the thickness of crushed rock could be permanently or temporarily increased. Permanent Drainage Systems A permanent, or temporary, drainage system is recommended in conjunction with the granular base. The drain system should include 4-inch diameter Contech A2000, or equivalent, drainage pipes designed to provide positive drainage to a sump. The pipes should be laid in 12-inch wide trenches excavated at least 6 inches below the bottom of the granular base layers. A non-woven geotextile such as Contech C60NW, or equivalent, should be used to line the bottom and sides of the pipe trenches. The pipes should be laid directly on the fabric and a minimum 4-inch cover of NDOR "47B" fine aggregate for concrete should be placed over the top and to the sides of the drain pipes. The pipe slots or perforations should be sized to prevent excessive infiltration of the 47B sand gravel material. The pipes should have center-to-center spacings designed to provide unobstructed drainage distances in the granular base of less than approximately 30 feet. All permanent pipes should be provided with cleanouts. The permanent drain pipe system could be installed prior to installation of the granular base if the pipes are of adequate strength or are trenched in deep enough to withstand loads imposed by construction equipment and the system is otherwise protected against damage or fouling during construction. This would permit usage of the system in the basement area to assist in dewatering efforts during construction. However, the perimeter swale discussed previously in this report should still be used for collection and removal of surface or seepage water from the excavation sideslopes. A non-woven fabric or silt fence should be provided on the granular base side of the perimeter swale to protect the base against fouling with fines from the surface runoff.

The City will at no time levy special assessments against the Private Development Site, the owner or developer of the Private Development Site, Union Pacific, or their successors or assigns, to pay for the original construction of any improvements made in connection with or pursuant to this Agreement or any amendments. The City finds and agrees that the improvements made by it pursuant to this Agreement are for the general benefit of the public within the City and are not local in nature. To the full extent that it lawfully may do so, the City will indemnify, defend and hold Union Pacific, the owner or developer of the Private Development Site and their respective successors and assigns, harmless from any suit, damage, assessment, injury or claim (including reasonable legal fees) which Union Pacific, the owner or developer of the Private Development Site, or their respective successors or assigns, may suffer or incur as a result of any attempt by the City to impose a special assessment for such improvements or to recover any funds or damages from the Private Development Site, Union Pacific, the owner or developer of the Private Development Site, or their respective successors or assigns, by reason of no such special assessment having been made by the City. 2.8 Notices to Proceed. The City will not proceed with the performance of any of its construction, Private Development Site acquisition or site preparation, or street improvement obligations under this Agreement until Union Pacific notifies the City in writing to proceed with such performance. If the City proceeds with such performance prior to receipt of notice to proceed, then Union Pacific will have no obligation to reimburse the City if Union Pacific elects to terminate this Agreement pursuant to Section 6.1. 2.9 Acquisition and Preparation of Private Development Site, The City will acquire Marketable Title to the Private Development Site. If City is unable to do so by purchase agreement or donation within ninety (90) days after receipt by City of notice to proceed with site acquisition from Union Pacific, the City will use its power of eminent domain to acquire, within one hundred eighty (180) days after receipt by City of the notice to proceed, those portions of the Private Development Site not owned or under contract to be acquired by the City, including fee simple title, any leasehold estates and rights of tenants under leases whatsoever without exception, easement rights, or other interests necessary to acquire Marketable Title. If, despite its best efforts, the City has not acquired any portion of the Private Development Site within such time period, and Union Pacific has not elected to terminate this Agreement, the City will continue to use its best efforts to acquire the balance of the Private Development Site at the earliest possible date. Within ninety (90) days after the City has acquired Marketable Title to the Private Development Site, the City will demolish all improvements (including below- grade foundations and other improvements), relocate, cap or remove utilities (including, without limitation, relocation of fiber optic and communication facilities) in accordance with the Utility Relocation Plan, remediate any environmental contamination to the satisfaction of Union Pacific and Union Pacific designee, and excavate and otherwise perform work to bring the Private Development Site to a construction-ready condition substantially in accordance with the Site Preparation Preliminary Plan, and with the Site C\Documents and Settings\clkbib\Desktcp\Redevelopment Agrm1 32501 doe 6 Preparation Final Plan to be prepared by the City and approved by Union Pacific and Union Pacific's designee.

Section 3. OBLIGATIONS OF UNION PACIFIC. 3.1 Transfer of Union Pacific Properties. In exchange for the City's conveyance of the Private Development Site to Union Pacific's designee in a construction-ready condition, all of Union Pacific's right, title and interest in the Wesco Building and in the Union Pacific Building will be transferred to the City, "as-is" and without any representations or warranties. The transfer will occur upon conveyance to Union Pacific's designee of Marketable Title to the Private Development Site pursuant to Section 2.9. If the transfer occurs prior to the date (the "Moving Period Date") which is one hundred eighty (180) days after issuance of a certificate of occupancy for the Office Tower, then the City will grant to Union Pacific exclusive use and occupancy of the Union Pacific Building, for no additional consideration, until the Moving Period Date occurs. After the Moving Period Date, the City will grant to Union Pacific exclusive use and occupancy of the lower level file storage space in the Union Pacific Building and such other office space in the Union Pacific Building as Union Pacific may elect, for no additional consideration other than a proportionate share of Operating Expenses, until the Union Pacific Building is transferred by the City to a developer and the space is required for redevelopment to uses other than office. The City recognizes the public need for daycare facilities in Downtown Omaha, and therefore the City will cause the redevelopment of the Union Pacific Building to include a daycare center for use by Union Pacific employees and employees of other downtown businesses or, C,Documents and Settings lclkbIb\Desktop\Redevelopment Agrmt 32501 doe 7 alternatively, will use its best efforts to cause such a daycare center to be developed elsewhere in Downtown Omaha within not more than three (3) blocks from the Office Tower. The transfer of the Union Pacific Building to City will be made subject to this covenant of City. City will reimburse Union Pacific for the cost of relocating Union Pacific's records operation from the Wesco Building; including, without limitation, moving the records operation to both the temporary and permanent new locations, rent for the temporary location for a period not to exceed one (1) year, and, additionally, all relocation assistance payments under the Relocation Assistance Act to which Union Pacific would be entitled as a Displaced Person. City will give Union Pacific not less than sixty (60) days written notice of the date that City intends to commence construction of the Parking Garage such that Union Pacific will be required to vacate the Wesco Building. 3.2 Notices to Proceed.

RECITALS This Agreement is made with respect to the following facts: A. Pursuant to a Redevelopment Agreement (the "Redevelopment Agreement") dated , 200_, by and between the City and UP, the City has agreed to lease to UP, and UP has agreed to lease from the City, approximately one thousand two hundred eighty (1,280) daytime parking spaces (the "Parking Spaces") in the Parking Garage (as defined in the Redevelopment Agreement) to be constructed and owned by the City. AGREEMENT NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are acknowledged, the City and UP agree as follows: ARTICLE I PARKING SPACES The City, for and in consideration of the rents herein reserved and of the covenants and agreements contained herein on the part of UP to be performed, leases to UP and UP lets from the City, for use between 6:00 A.M. and 6:00 P.M. Monday through Friday, and 6:00 A.M. and 1:00 P.M. on Saturdays (but only as to 420 of the Parking Spaces), the Parking Spaces which will be located in the building referred to in the Redevelopment Agreement as the Parking Garage, to be constructed on Block 90, Original City of Omaha, as surveyed and lithographed in Douglas County, Nebraska (the "Parking Facility"), together with the right of ingress to and egress from the Parking Spaces over and across such portions of the Parking Facility as reasonably may be designated by the City from time to time. If any of the Parking Spaces are unavailable for use because the Parking Facility has been damaged or destroyed or because of the need for maintenance, repairs or alterations, and other parking spaces in other City parking facilities are usable for parking, the City will make such other spaces available to serve as UP's Parking Spaces. 0\Documents and Settingslclk6tb\Desktop\Redevelopment Agrmt 32501 dog I ARTICLE 2 TERM 2,1 Commencement of Term. The basic term of this Agreement (the "Basic Term") will commence on the date the Parking Facility is substantially completed and ready for use by UP and Authorized Users (as defined below) (the "Commencement Date"), and terminate on a date which is the last day of the 240th full calendar month after the Commencement Date (the "Expiration Date"). 2.2 Options to Extend. (a) UP may, at its option, extend the Term for one five-year period commencing on the twentieth (20th) anniversary of the first of the first full calendar month of the Basic Term and terminating at the end of the sixtieth (60th) full calendar month thereafter (the "First Extended Term"). If UP exercises its option with respect to the First Extended Term, UP may, at its option, further extend the Term for one five- year period commencing on the twenty-fifth (25th) anniversary of the first day of the first full calendar month of the Basic Term and terminating at the end of the sixtieth (60th) full calendar month thereafter (the "Second Extended Term"). If UP exercises its option with respect to the Second Extended Term, UP may, at its option, further extend the Term for one five-year period commencing on the thirtieth (30th) anniversary of the first day of the first full calendar month of the Basic Term and terminating at the end of the sixtieth (60th) full calendar month thereafter (the "Third Extended Term"). If UP exercises its option with respect to the Third Extended Term, UP may, at its option, further extend the Term for one five-year period commencing on the thirty-fifth (35 ) anniversary of the first day of the first full calendar month of the Basic Term and terminating at the end of the sixtieth (60th) full calendar month thereafter (the "Fourth Extended Term"). The First Extended Term, Second Extended Term, Third Extended Term and Fourth Extended Term are each called an "Extended Term." As used in this Agreement, "Term" means the Basic Term together with any Extended Term with respect to which UP has properly exercised its option. (b) To exercise each option described in Section 2.2(a), UP must deliver to the City written notice of the exercise thereof not later than thirty (30) days before the expiration of the then-current Term. ARTICLE 3 MONTHLY RENT 3.1 Monthly Rent. (a) Commencing on the Commencement Date and continuing through the Term, UP will each month pay rent ("Monthly Rent") for the Parking Spaces. Monthly Rent for the initial partial month, if any, and the first sixty full months of the Term is $70.00 per Parking Space per month ($89,000.00 per month). The Monthly Rent for the sixty-first month through the one hundred twentieth month is C 1Docurnenl5 nd Settings\dkbtb\DeskIopVRedevelopment Agrmt 32501 dec 2 $75.00 per Parking Space per month ($96,000.00 per month). The Monthly Rent for the one hundred twenty-first month through the one hundred eightieth month is $85.00 per Parking Space per month ($108,800.00 per month). The Monthly Rent for the one hundred eighty-first month through the two hundred fortieth month is $95.00 per Parking Space per month ($121,600.00 per month). (b) The Monthly Rent during any Extended Term will be the fair market rental rate for the Parking Spaces as of the first day of the Extended Term. The fair market rental rate is the average monthly rental rate being charged for leases of parking spaces in comparable parking garages in downtown Omaha at that time. If the City and UP cannot agree on the fair market rental rate for an Extended Term by the first day of that Extended Term, then, until the fair market rental rate for the Extended Term has been determined, UP will continue to pay rent at the then-applicable rate. When the fair market rental rate for the Extended Term has been determined, UP will promptly pay the City any additional rent for the time since the commencement of the Extended Term, or, if the fair market rental rate is less than the then-applicable rental rate paid by UP, UP may credit any overpayment against Monthly Rent next becoming due. If the City and UP cannot agree on the fair market rental rate for an Extended Term by the first day of that Extended Term, then each of them will appoint a qualified appraiser to determine the fair market rental rate, the two appraisers so appointed will appoint a third and the three appraisers so appointed will jointly determine the fair market rental rate. The City will make its records of rates charged for parking in other downtown parking garages owned or operated by the City available to UP and the appraisers for this purpose. If the three appraisers do not agree, then the median fair market rental rate determined by the three appraisers will be considered the fair market rental rate for purposes of this Agreement. Each party will pay the fee of the appraiser appointed by it, and one-half of the fee of the third appraiser. UP may elect to terminate its exercise of the option to extend by giving the City written notice of termination within thirty (30) days after the fair market rental rate for the Extended Term is determined. 3.2 Payment. Monthly Rent will be paid in advance on or before the Commencement Date and on or before the first day of each successive calendar month during the Term. If the Commencement Date is a day other than the first day of the calendar month, Monthly Rent will be appropriately prorated. Monthly Rent will be paid to the City without notice or demand, in lawful money of the United States of America, at the office of the Omaha City Finance Department or to such other person or at such other place as the City may from time to time designate in writing. 3.3 Interest on Late Payments. All Monthly Rent, if not paid when due, will bear interest from the due date until paid at the lesser of (a) the highest interest rate permitted by law, or (b) the then-current "Base Rate" (as defined below) plus 2%, provided, however, that no such interest will be payable with respect to any payment of Monthly Rent that is received by the City within twenty (20) days after receipt by UP of notice of rental delinquency from the City. The "Base Rate" is the rate of interest from C\Documents and Setthngs1c1kbybkDesklooNRedevelopment Agrmt 32501 doc 3 time to time established by the State Court Administrator pursuant to Neb. Rev. Stat. § 45-103 (Reissue 1993). ARTICLE 4 OPERATING EXPENSES The City will pay, and indemnify and hold UP harmless from the payment of, all costs of management, operation and maintenance of the Parking Facility, including without limitation, the following costs: real and personal property taxes and assessments allocable to the Parking Facility (and any tax levied in whole or in part in lieu of or in addition to real property taxes), wages, salaries and compensation of employees, costs of consulting, accounting, legal, janitorial, maintenance, guard and other services, management fees, costs of power, water, waste disposal and other utilities, materials and supplies, costs of maintenance and repairs, costs of insurance obtained with respect to the Parking Facility, ground lease payments, depreciation on personal property and equipment, any general assessments, special assessments, or other fees or charges assessed by any entity authorized to operate, maintain, and repair the Parking Facility. ARTICLE 5 CITY'S INSURANCE Throughout the Term, the City will, at its sole expense, obtain and keep in force commercial general liability insurance with a combined single limit of not less than $5,000,000.00 per occurrence, including coverage for contractual liability and personal injury without limitation. The coverage limit requirement will be increased from time to time by the City upon reasonable request of UP to reflect then-current risk management practices. The City may satisfy some or all of the insurance coverage required under this Section 5.1 through a self-retention program. Nothing in this Agreement is intended to impose any insurance requirements upon UP. ARTICLE 6 USE 6.1 Entry System; Reserved Spaces; and Authorized Users. (a) The City will construct and at all times maintain a card entry system for ingress to and egress from the Parking Facility. UP will be issued such number of cards as it requests from time to time. If a card is lost or stolen, UP may notify the City and the City will promptly cancel the lost or stolen card. There will be a $10.00 charge for each card issued to UP. UP will determine the persons entitled to use its Parking Spaces and will distribute its cards to such persons (such persons are referred to in this Agreement as "Authorized Users"). UP and the City may agree on a different mutually acceptable controlled entry system to accomplish the intent of this paragraph. C\Documents and SetungslcIkbjb\DesktoplRedevelopment Agrmt 32501 doc 4 (b) The City will number and identify the Parking Spaces as "reserved." UP may, but is not required to, designate which of the reserved Parking Spaces each of the Authorized Users has the right to use. The City will not be liable for use of any of the Parking Spaces by persons other than Authorized Users so long as the City makes reasonable efforts to prevent such usage (including towing unauthorized vehicles parked in the Parking Spaces upon notification by UP). 6.2 Manner of Use and Access. UP and Authorized Users will use the Parking Spaces only for parking of passenger model vehicles, small vans, and small trucks. UP and Authorized Users will use the Parking Spaces in a safe, careful and proper manner, in compliance with any present or future governmental or quasi- governmental laws, rules, regulations or orders. ARTICLE 7 MAINTENANCE AND ALTERATIONS 7.1 Operation and Maintenance of Parking Facility. The City, at its expense, and through such agents, representatives or independent contractors as it may designate, will operate, maintain and keep the Parking Facility in first class condition and repair, reasonable wear and tear excepted, in such manner as will ensure UP and any Authorized Users the continued availability, use and enjoyment of the Parking Spaces during the Term. Such maintenance includes, but is not limited to, keeping the Parking Facility reasonably clean, free of debris, ice and snow, and appropriately sanding, salting, painting and striping the Parking Facility and Parking Spaces. The City will have the right to enter upon or restrict access to the Parking Spaces or any of them for purposes of performing the City's obligations under this Section 7.1, provided that the City will use its best efforts in connection with such entry or restriction of access to minimize any disruption to any Authorized User's use of the Parking Spaces. UP will be entitled to abatement of Monthly Rent on a prorata basis during the period of unavailability of any Parking Space unless an alternate parking space is made available in the Parking Facility or in the vicinity of the Parking Facility. In addition to UP's other remedies, Union Pacific may at its option (but with no obligation to do so) correct any deficiencies in the City's repair or maintenance of the Parking Facility that the City fails to correct within ten (10) days after written notice from Union Pacific, in which event the expense incurred by Union Pacific shall be offset against one or more future installments of rent. 7.2 Alterations and Improvements. The City may, from time to time, make additions, improvements and alterations to the Parking Facility; provided, however, that any addition, alteration, or improvement (other than as necessary to operate and maintain the Parking Facility as provided in Section 7.1) which materially impairs access to or use of the Parking Spaces, either temporarily or permanently, will be made only with reasonable prior notice to UP. If any such addition, improvement or alteration to the Parking Facility causes Parking Spaces to be unavailable for use and alternate C\Documents and Settings\clkblb5Desktop\Redevelopment Agrmt 32501 doc 5 spaces are not available in the Parking Facility, Monthly Rent will abate on a prorata basis. ARTICLE 8 CASUALTY If the Parking Facility is damaged or destroyed in whole or in part by any casualty, the City will promptly commence and diligently complete any necessary repairs or restoration. During any period when any Parking Spaces are not available for use, Monthly Rent will abate on a prorata basis. ARTICLE 9 ASSIGNMENT AND SUBLETTING UP may assign this Agreement or sublet one or more of the Parking Spaces to any other party. If UP requests the City to do so and if the proposed assignee's creditworthiness is reasonably acceptable to the City, the City and UP will amend this Agreement to reduce the number of Parking Spaces leased to UP and the City will enter into a separate Parking Lease Agreement with such third party in substantially the form of this Agreement. ARTICLE 10 QUIET ENJOYMENT So long as UP pays Monthly Rent and observes and performs all the terms, covenants and conditions of this Agreement on UP's part to be observed and performed, UP may peaceably and quietly enjoy the Parking Spaces subject to the terms and conditions of this Agreement. ARTICLE 11 DEFAULT 11.1 Events of Default. The following events are referred to collectively as "Events of Default," or individually, as an "Event of Default": (a) UP defaults in the due and punctual payment of Monthly Rent, and such default continues for thirty (30) days after written notice from the City; (b) This Agreement or the Parking Spaces are taken upon execution or by other process of law directed against either party, or are subject to any attachment at the instance of any claimant against either party and such attachment is not discharged with sixty (60) days after its levy, and the party subject to such execution or attachment is not actively seeking such discharge; C\Documents and Sett gs\clkbjb\Desktop\Redevelopment Agrmt 32501 doc 6 (c) Either party files a petition in bankruptcy or insolvency, or a petition for reorganization or arrangement under the bankruptcy laws of the United States or under any insolvency act of any state, or admits the material allegations of any such petition by answer or otherwise, or is dissolved, or makes an assignment for the benefit of creditors. (d) Involuntary proceedings under any such bankruptcy law or insolvency act or for the dissolution of either party are instituted against such party or a receiver or trustee is appointed for all or substantially all of the property of such party, and such proceeding is not dismissed or such receivership or trusteeship vacated within sixty (60) days after such institution or appointment, and such party is not actively pursuing the vacation of such action; or (e) Either party breaches any of its other obligations under this Agreement, and such breach continues for thirty (30) days after notice by the non- breaching party to the breaching party or, if such default cannot reasonably be cured within such 30-day period, the breaching party fails to commence such cure within such 30-day period or thereafter fails to proceed diligently to cure such breach within a reasonable time, but in no event more than an additional one-hundred twenty (120) days. 11.2 Remedies. If an Event of Default occurs, then the non-defaulting party has the right, at its election, to: (a) Subject to the provisions of Section 13.4, give the defaulting party written notice of termination of this Agreement, in which case UP's right to possession of the Parking Spaces will cease and this Agreement will be terminated thirty (30) days from the first day of the calendar month following the date of such notice; or (b) With respect to UP's default, and subject to the provisions of Section 13.4, the City may after demand and notice, reenter and take possession of the Parking Spaces or any of the Parking Spaces, repossess the same, expel UP and those claiming through or under UP, including, without limitation, the Authorized Users, and remove the effects of both. Should the City elect to reenter as provided in this subsection (b), or should the City take possession pursuant to legal proceedings or pursuant to any notice provided by law, the City may, from time to time, without terminating this Agreement, collect and receive payments from Authorized Users for use of all or any portion of the Parking Spaces. No such reentry or taking possession of the Parking Spaces by the City will be construed as an election on the City's part to terminate this Agreement unless a written notice of such intention is given to UP. No notice from the City under this subsection or under a forcible or unlawful entry and detainer statute or similar law will constitute an election by the City to terminate this Agreement unless such notice specifically so states. The City reserves the right following any such reentry or reletting to exercise its right to terminate this Agreement C\Documents and Settings\clkbjb\Desktop\Redevelopment Agrmt 32501 doc 7 by giving UP written notice in accordance with subsection (a), in which event this Agreement will terminate as specified in such notice; or (c) With respect to the City's default, whether in the performance of the City's duties under Article 7 or otherwise, UP may provide written notice to the City specifying the nature of such default, and, if the City fails to cure such default within thirty (30) days following receipt of such written notice, UP may cure such default and offset the cost and expense of such cure against one or more future installments of Monthly Rent. 11.3 Certain Damages. If the City does not elect to terminate this Agreement as permitted in subsection 11.2(a), but instead elects to take possession as provided in subsection 11.2(b), UP will pay to the City: (a) Monthly Rent which would be payable under this Agreement if such repossession had not occurred, less (b) the proceeds, if any, received by the City for the use of the Parking Spaces. UP will pay such adjusted Monthly Rent to the City monthly on the day on which such Monthly Rent would have been payable under this Agreement if possession had not been retaken, and the City will be entitled to receive such adjusted Monthly Rent from UP on each such day. The City will use its best efforts to relet the Parking Spaces and mitigate its damages on account of UP's default. if the City elects to use the Parking Spaces for its own employees or permittees and charge less than the Monthly Rent rate per Parking Space, UP will be entitled to a credit for each such space equal to the Monthly Rent for such space. 11.4 Cumulative Remedies. Unless otherwise provided in this Agreement, each right and remedy provided in this Agreement is cumulative and in addition to every other right or remedy provided in this Agreement or now or hereafter existing at law or in equity or by statute or otherwise, and the exercise or beginning of the exercise by either party of any one or more of such rights or remedies will not preclude the simultaneous or later exercise by such party of any or all other such rights or remedies. ARTICLE 12 PURCHASE OPTION At any time during the last six (6) months of the Basic Term, or of any Extended Term, UP may elect to purchase the Parking Facility and all of Block 90 for the fair market value. The option may be exercised only by written notice ("Option Notice") given by UP to the City. If UP and the City are unable to agree on the fair market value within sixty (60) days (the "Agreement Date") after the Option Notice is given, then each of them will appoint a qualified appraiser within thirty (30) after the Agreement Date. The two appraisers will appoint a third appraiser within thirty (30) days after the appointment of the last of the two appraisers. The three appraisers so appointed will determine the fair market value within sixty (60) days after the appointment of the third appraiser. If the fair market value as so determined is less than the amount required to retire the City's indebtedness with respect to the Parking Facility and Block 90, then the C\Documents and Settings\clkby61oesktop\Redevelopment Agrmt 32501 doc 8 Option Notice will be void and of no effect. Otherwise, the sale of the Parking Facility and Block 90 to UP will close within thirty (30) days after the fair market value is determined. At the closing of such sale, the City will convey marketable title to the Parking Facility and all of Block 90 to UP by General Warranty Deed. ARTICLE 13 MISCELLANEOUS 13.1 Time of the Essence. Time is of the essence of each and every provision of this Agreement. 13.2 No Waiver.

CITY OF OMA .A, k F By: Title: Mayor of the City of Omaha Date: L' Zb Di Attest: By: City Clerk Approved as to Form: By: UNION PACIFIC RAILROAD COMPANY By: R/14 (0 424 to Title: ge • Date: .SA d f C.\0ccuments and SettingsklkbjbWesktoplRedevelopment Artmt 32501 doe 12 Amended EXHIBIT 3 SITE PREPARATION PRELIMINARY PLAN The City will excavate the site to a uniform depth, installing an 18" sand and crushed limestone wearing surface and dewatering layer to the Final Design Subgrade Level utilizing the methods and techniques described in the Project Site soils report prepared by Terracon, dated November 15, 2000, attached as Exhibit A, and incorporated by this reference and subsequently detailed in the Office Tower's final design. The City will install a temporary dewatering system in the 18" layer (6" perforated pipe every 100' on center in both directions and two sump pits at opposite diagonal corners). The City will excavate the site such that the banks of the excavation along the entire periphery of the site will be left at a 45 degree slope down from the street curb line with well compacted cohesive earth and completely covered with staked in place heavy duty plastic sheeting. The developer will install the Office Tower's permanent underdrain system in the granular fill as discussed in the Terracon report and subsequently detailed in the project's final design. The intent of the above is to bring the site to a stable construction-ready condition enabling the Office Tower's contractor, upon City's completion of the above work, to occupy the site and begin foundation work upon a completely excavated and stabilized site. Before proceeding with work described above, the City will prepare, and gain Union Pacific's and the developer's approval of, Final Site Preparation Plan, which will incorporate both this intent, and the work described above. The design drawings and specifications necessary for the installation of the temporary dewatering system and 18" wearing and temporary drainage layer, the 45 degree slopes of the excavation, and excavation to the Final Design Subgrade elevation as required by Exhibit A (the "Design Documents") will be prepared and provided to the City by professional civil engineering and geotechnical consultants (the "Consultants") engaged on behalf of Union Pacific. The Design Documents prepared by the Consultants will be forwarded to the City for incorporation by the City into the bidding and procurement specifications and drawings for all of the work necessary to complete its obligations required by this Agreement (the "Contract Documents") upon which Union Pacific will have right of final review and approval prior to issuance for bid. The City will assemble and issue the Contract Documents for bid to contractors. Once the City has selected and entered into a contract with the contractor who will perform the work (the "Contractor") and the Contractor has begun work, the Consultants, on an as-needed basis, will advise the City rendering technical assistance and advice as to the Contractor's progress and adherence to the requirements of the Design Documents as contained in the Contract Documents. The City will cause the Contractor to execute the work as required by the Contract Documents and as modified by the Consultants' field observations and directions during the progress of the work. The City will remain responsible for bringing the site to a stable construction-ready condition as described above and in the Contract Documents and delivering the site to the developer's contractor. EXHIBIT A TO EXHIBIT 3 Drained Granular Base Recommendations We understand that the City of Omaha will remove all components from prior construction on the site down to the natural, lean clay subgrade soils. Relative to the currently estimated design subgrade elevation, it is anticipated that this may require additional cut in the southwest corner of the site, and fill in the northeast corner. Relatively wet, soft, and disturbance-sensitive lean clay soils are anticipated to be encountered, over most of the site, below the foundations and floor slabs of the prior construction. These soils are expected to be unstable under the loads of most conventional construction equipment. The natural lean clays that may presently be somewhat drier and more stable in the higher areas of the site will also be susceptible to softening and degradation of stability upon wetting and/or exposure to freeze/thaw cycles. For these reasons, it would be beneficial to combine excavation to design subgrade elevation with the demolition phase work to permit the necessary grading of the sensitive soils to be performed remotely with a hoe-type excavator supported on the existing rubble fill, as removals proceed across the site. This would also permit timely placement of a protective base to reduce subsequent deterioration of the exposed subgrade soils. In summary, the site demolition program should be coordinated with subsequent construction plans to the extent required to protect the subgrade soils against excessive disturbance during, or degradation following, the site demolition phase of work. This is recommended to avoid added costs or delays that could otherwise be incurred, In order to provide a stable base for construction equipment and subsequent floor slab support, it is recommended that soil over-excavation and replacement with granular material be performed. The following recommendations have been developed with the intent that the granular base survive construction to be incorporated in the permanent granular drainage systems below the planned building. It is recommended that the soils be over-excavated to a minimum depth of 18-inches below the proposed bottom of floor slab elevation in the building area. Where over- excavation from demolition extends only nominaIIy deeper than this minimum depth, those areas could be backfilled with the sand/gravel base material described below. In areas where a significant thickness of new fill is required, granular material could be used as necessary to bridge soft subgrade soils for support of cohesive fill placement. Excavation in areas of disturbance sensitive subgrade soils should be performed remotely with a large, hoe-type excavator. The hoe bucket should be equipped with wide spade teeth. The soil should be excavated in thin horizontal lifts in a manner that avoids subgrade disturbance due to soil suction that can be created under the bucket. Prior to placement of the granular base, permanent drainage pipes should be installed in the over- excavated subgrades, as discussed below for the permanent drainage system. Consideration should be given to providing a longitudinal crown or swale in the soil subgrade to promote drainage toward the permanent drain lines. However, the recommended minimum thicknesses of granular material should be preserved. Clean, well-graded, sand and gravel meeting State of Nebraska Department of Roads specifications for 47B "fine aggregate for concrete" should be drifted head in an initial lift at least ten inches thick onto the over-excavated subgrade. The sand should be drifted ahead with a wide-track dozer sized to avoid disturbance of the underlying clays and compacted with a large vibratory plate or moderate sized vibratory smooth steel drum self-propelled roller. A minimum eight-inch thickness of 1%2-inch minus crusher run limestone, or crushed concrete, containing less than ten percent material passing the No. 200 sieve should then be drifted ahead onto the sand/gravel base and compacted. The granular base materials should be compacted to at least 65 percent relative density in accordance with ASTM D-4253 and 4254. The soil over-excavation and granular base placement should extend at least several feet outside the perimeter of the building structure. Silt-fencing or grading in the form of ditches or sumps should also be provided around the perimeter of the granular base to divert surface run-off and silt from entering into the completed base area. Provisions should also be made to achieve control and prompt removal of surface water that collects in the excavation. Use of geotextile or geogrid is not recommended below the granular base stabilization layers or drainage materials due to the potential interference with foundation and utility installation. Care should be taken to avoid excessive fouling of the granular base materials with spoils from excavations or dirt carried in by construction equipment. A thin layer of common fill sand should be spread two to three inches thick over the crushed rock to reduce infiltration of soil, drilling slurry, concrete or other fines into the rock during construction. Care should be taken not to penetrate significantly into the crushed stone during spoils removal. The resulting surfaces are generally expected to be capable of supporting limited repetitions of construction equipment reasonably limited in ground contact pressure. However, excessively heavy or concentrated loads or numerous repetitions of moderately heavy loads could cause failure and should be avoided. Alternatively, the thickness of crushed rock could be permanently or temporarily increased. Permanent Drainage Systems A permanent, or temporary, drainage system is recommended in conjunction with the granular base. The drain system should include 4-inch diameter Contech A2000, or equivalent, drainage pipes designed to provide positive drainage to a sump. The pipes should be laid in 12-inch wide trenches excavated at least 6 inches below the bottom of the granular base layers. A non-woven geotextile such as Contech C6ONW, or equivalent, should be used to line the bottom and sides of the pipe trenches. The pipes should be laid directly on the fabric and a minimum 4-inch cover of NDOR "47B" fine aggregate for concrete should be placed over the top and to the sides of the drain pipes. The pipe slots or perforations should be sized to prevent excessive infiltration of the 47B sand gravel material. The pipes should have center-to-center spacings designed to provide unobstructed drainage distances in the granular base of less than approximately 30 feet. All permanent pipes should be provided with cleanouts. The permanent drain pipe system could be installed prior to installation of the granular base if the pipes are of adequate strength or are trenched in deep enough to withstand loads imposed by construction equipment and the system is otherwise protected against damage or fouling during construction. This would permit usage of the system in the basement area to assist in dewatering efforts during construction. However, the perimeter swale discussed previously in this report should still be used for collection and removal of surface or seepage water from the excavation sideslopes. A non-woven fabric or silt fence should be provided on the granular base side of the perimeter swale to protect the base against fouling with fines from the surface runoff P:\Law111808p.doc
