[All Wards] Recommendation: Adopt the Ordinance. Background: Chapter 8.12 of the Davenport Municipal Code establishes standards for identifying and addressing nuisance conditions that impact public safety and quality of life. Section 8.12.015 defines a “problem area nuisance” based on the occurrence of specified criminal acts or violations within a defined timeframe and proximity to a property. Iowa Code section 708.6 has replaced the term "Terrorism" with "Intimidation with a Deadly and Dangerous Weapon", so the City is updating our local code to reflect this change. Also, adding "Felon in possession of a firearm" aligns the nuisance ordinance with serious offenses identified in state law and strengthens the City’s ability to proactively address properties associated with dangerous activity. This update supports consistent application of the code and provides an early, preventative enforcement tool focused on public safety. Attachments: 1. Ordinance 2. Original 8.12.015 3.

Unauthorized signs, signals or markings. [Ord. 84-247 § 6.5] No person shall place, maintain, or display upon or in view of any person upon a street any sign, signal, marking, or device which purports to be or is an imitation of or resembles an official parking sign, curb or other marking, traffic control device or railroad sign or signal, or which attempts to direct the movement of traffic, or which hides from view or interferes with the effectiveness of any official traffic control device or any railroad sign or signal, if such sign, signal, marking, or device has not been authorized by the City traffic engineer and no person shall place or maintain any traffic sign or signal bearing thereon any commercial advertising.

The system may be managed by a private contractor that owns and operates the requisite equipment with supervisory control vested in the City's Police Department. Video images shall be provided to the Police Department by the contractor for review. The Police Department will determine which vehicle owners are in violation of the City's traffic control ordinances and are to receive a notice of violation for the offense. B. Definitions. 1.

[All Wards] Recommendation: Adopt the Ordinance. Background: The proposed amendment adds the phrase “unless otherwise posted or established in this code” to clarify that the listed speed limits serve as default speeds and may be superseded by posted signs or other speed limits adopted elsewhere in the Municipal Code. This clarification ensures consistency with existing traffic control practices and provides clear legal authority for enforcing posted speed limits where conditions warrant different speeds. The added language improves enforcement clarity, reduces ambiguity, and strengthens the legal defensibility of speed regulations without changing the intent or overall structure of the ordinance.

[Ward 3] Recommendation: Adopt the Ordinance. Background: West 3rd Street currently has a posted speed limit of 35 miles per hour between Telegraph Road and Brown Street, and a posted speed limit of 25 miles per hour east of Brown Street. Prior to the conversion of a portion of 3rd Street from a one-way roadway to a two-way roadway, the roadway operated with three travel lanes in a single direction, which provided wider operating space and contributed to higher vehicle speeds. Following the conversion, part of the corridor now consists of one travel lane in each direction. This change in roadway configuration has significantly altered traffic operations and has reduced the ability of vehicles to travel at higher speeds. Given the current two-way configuration, the existing 35-mile-per-hour speed limit is no longer consistent with the roadway’s function, lane arrangement, or adjacent land uses. Reducing the speed limit to 25 miles per hour for the segment of West 3rd Street that was converted to two- way traffic would create consistency with the adjacent segment east of Brown Street, better align with current operating conditions, and support overall traffic safety. For these reasons, staff recommends reducing the posted speed limit to 25 miles per hour on West 3rd Street between Marquette Street and Brown Street. Attachments: 1.

[All Wards] Recommendation: Adopt the Ordinance. Background: Davenport Municipal Code Chapter 3.20 governs the City’s local sales and service tax allocation. Section 3.20.030 currently states that revenues allocated for capital improvements may be used for other lawful purposes as critical needs arise, and that the Council may allocate those revenues to other purposes by resolution upon a two-thirds vote. The City Attorney’s Office has reviewed this provision in light of applicable state law governing local option sales and services tax (Iowa Code Chapter 423B) and concludes the Municipal Code of Davenport, Iowa, should be revised to avoid any implication that dedicated allocations may be reallocated by resolution where state law requires different procedures. This Ordinance is a Code cleanup and compliance measure which will achieve the following: 1. Amends Section 3.20.020 to remove internal language suggesting changes may occur "by other provisions of this chapter" and clarificies the allocation remains fixed unless changed as provided by state law. 2.

[All Wards] Recommendation: Adopt the Resolution. Background: On May 14, 2025, the City Council placed a moratorium on solar farms as a principal use and freestanding solar panels as an accessory use until November 14, 2025. The moratorium was placed in order to provide staff time to evaluate current regulations and propose any necessary revisions. Staff completed review and has worked with the Plan and Zoning Commission on revisions to the solar sections of the Zoning Code. The Plan & Zoning Commission has reviewed a proposed text amendment regarding solar within the City, and has unanimously recommended approval. On November 12, 2025, the moratorium was extended until February 12, 2026, to allow the necessary time for the Council to move through the review process. On December 3, 2025, City Council voted to postpone the solar ordinance text changes until after completion of the West Davenport Land Use and Infrastructure Study. Therefore, the current moratorium will expire prior to the Council's full review and consideration. The Resolution will extend the moratorium to June 25, 2026, to align with the completion of the West Davenport Land Use and Infrastructure Study. The current timeline for the West Davenport Land Use and Infrastructure Study anticipates a presentation by the consultant of land use concepts to Council in mid- to late-March for review and discussion. Following the presentation, the consultant will refine the land use concepts and the utility and transportation necessary to support the land uses. The completion of the plan, which includes adoption by council, is tentatively anticipated by the end of June 2026, but is subject to change. Staff has not been contacted regarding any potential solar farms or freestanding accessory solar at this time. As currently proposed, the moratorium will automatically terminate early if the Council adopts text amendments to the solar regulations in the Zoning Code prior to June 25, 2026. Attachments: 1.

RESOLUTION extending the moratorium on new solar farms as a principal use and freestanding solar panels as an accessory use until June 25, 2026, to align with the anticipated completion of the West Davenport Land Use and Infrastructure Study. WHEREAS, the City of Davenport regulates the uses, special uses, and accessory uses of its zoning districts; and WHEREAS, recent freestanding solar panel installation and inquiries into solar farms has spurred additional conversations and questions on how to best regulate solar; and WHEREAS, on May 14, 2025, the City of Davenport placed a moratorium upon new solar farms as a principal use and freestanding solar panels as an accessory use that expires on February 12, 2026; and WHEREAS, the City of Davenport has conducted research, and staff has proposed an ordinance to amend the sections of the Zoning Code related to Solar; and WHEREAS, at the October 14, 2025, Plan & Zoning Commission meeting, the Commission reviewed and recommended approval of amendments to the Zoning Code related to Solar; and WHEREAS, the City Council has postponed the adoption of the proposed Zoning Code text amendments until the West Davenport Land Use and Infrastructure Study has been completed to better understand future impacts to a large area of undeveloped land; and WHEREAS, the moratorium is set to expire prior to the completion of the West Davenport Land Use and Infrastructure Study and City Council’s full review and consideration of the proposed amendments; and WHEREAS, the City Council wishes to extend the moratorium until amendments of the Zoning Code related to Solar have been adopted or until June 25, 2026, whichever comes first. NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Davenport, Iowa, that the moratorium on new solar farms as a principal use and freestanding solar panels as an accessory use is hereby extended and shall remain in effect through 11:59 p.m. on June 25, 2026, unless earlier terminated upon the City’s adoption of an ordinance amending the solar regulations in the Zoning Code.

[Ward 3] Recommendation: Adopt the Resolution. Background: In September 2025, a five-year lease agreement with BZE Holdings, Inc, dba Boozie's Bar & Grill, was approved and executed for space in the Freight House property located at 401 West River Drive (roughly 4,500 square feet). That lease agreement provided four months with no rent payments due, three months with reduced rent, and then full rent payments would begin through the end of the five-year term. The rationale was that there would likely be two months of construction work planned by the City that would prevent the business from opening. The rehabilitation work involving windows, flooring, and HVAC has taken longer than originally anticipated and, as such, the business is now anticipating opening sometime in February, roughly two months later than they had anticipated. The business owner asked if two additional months with no rent payments could be inserted into the previously approved rent concession schedule to help accommodate the loss of revenue. The Riverfront Improvement Commission reviewed this request at their January meeting and voted in favor of a recommendation to the City Council to modify the lease by extending two more months of no rent payments. If approved, partial rent payment would be due starting April 1 and full rent would be due starting the month of July. If approved, the Mayor would be authorized to sign this amendment and staff would adjust the payment schedule accordingly. Attachments: 1. Resolution 2.

NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Davenport, Iowa, that an amendment to the Lease Agreement to revise lease payments with BZE Holdings, Inc, d/b/a Boozie’s Bar & Grill, at the Freight House is hereby approved. Passed and approved this 11th day of February, 2026. Approved: Attest: _________________________ _________________________ Jason Gordon Brian Krup Mayor Deputy City Clerk  AMENDMENT TO LEASE THIS AMENDMENT is made and entered into as of February _______, 2026, by and between the City of Davenport, an Iowa municipal corporation, (“Landlord”), and BZE Holdings, Inc., operating under the name “Boozie’s Bar & Grill,” an Iowa domestic for-profit corporation (“Tenant”). Article 3 of the existing Lease specifies: Four months of $0 rent, starting on the date of possession, would then be followed by three months of reduced rent equaling $750/mo. The three months of reduced rent would be due on February 1, 2026; March 1, 2026; and April 1, 2026. After these seven months, full rent payments will be due monthly, starting at $3,750/mo. This Amendment inserts two additional months of $0 rent before the three months of reduced rent begins. This would mean February and March rent would be $0 and that the three months of reduced rent ($750/mo.) would be for the months of April, May, and June. The first full month of full rent would be due on July 1, 2026. All other existing Lease provisions remain in place. _____________________________________ _____________________________________ Landlord: City of Davenport, Iowa Tenant: BZE Holdings, Inc.

As such, the citizens of Davenport expect us to be fiscally responsible stewards of our resources and environment. This expectation extends to all involved in the delivery of infrastructure projects and improvements. 2026 Highlighted Points of Concern | Inadequate Compliance and Required Improvement 1. Inlet Minor Adjustments: Please note that a clarification has been made to both 6010 1.08 E. 2. c. and 6010 3.04 B.3. clarifying that typically only inlet castings associated with minor adjustments are to be reused. All manhole castings (storm and sanitary) are to be replaced. In addition, storm inlet castings are to be replaced if associated with a major adjustment or replacement 2. Cleanup after Milling Operations: 7040 3.05 D. has been modified. Milled surfaces need to be cleaned using a vacuum equipped street sweeper no more than 24 hours prior to placement of the tack coat. Power brooming is still required and remains unchanged. 3. Keyed Joints: A note has been added to the end of 7010 modifying PV-101. Joint types “K” and/or “KT” are no longer allowed in the City of Davenport except as associated with bridge approach slabs. 4. Patch Thickness: Minimum patching thickness is now required to be 8”. An 8” patch represents a minimum 6” pavement thickness + the 2” additional thickness associated with patches. 5. Construction Survey: A new category of items has been added to 11,010 3.03 - G. Roadway appurtenances. The category has been added to account for both pavement fixtures and pavement markings. This survey shall be completed prior to pavement removal. The city has struggled with both fixtures being lost during the paving process as well as prime contractors not consulting with pavement marking subcontractors early enough in the project.

Access spacing shall be determined based on how the street functions relative to the definitions provided in Section 5B-1 of the SUDAS Design Manual. ‘Functions as’ refers to the operational role a street serves within the transportation network, as determined by the City Engineer, based on factors including Page 6 of 9  City of Davenport, General Supplement to 2026 SUDAS Design Manual _____________________________________________________________________________________ but not limited to traffic volumes, roadway geometry, access density, adjacent land use, connectivity, posted speed, and the degree to which the roadway provides mobility versus property access. A street’s functional role may differ from its Iowa DOT functional classification. For minor arterials and major collectors, direct access from individual properties shall be minimized and avoided where practicable. Property access should be provided from side streets, shared or joint-use driveways, or rear or cross-access easements between adjacent parcels. Table 5L-3.04 of the SUDAS Design Manual shall be used as the preferred access spacing standard for arterial and collector roadways. The minimum distances identified in Table 5L-3.05 of the SUDAS Design Manual may only be permitted when approved by the City Engineer based on site constraints, existing development patterns, or a demonstrated lack of reasonable alternative access. Access for local residential streets shall be limited to one (1) access drive per lot, unless otherwise approved by the City Engineer. Access for local commercial or industrial streets shall be limited to the minimum number of access points necessary to serve the development. Shared or joint-use access shall be required where feasible, as determined by the City Engineer. The maximum number of access points shall be determined by the driveway spacing criteria identified in 5l-3. 5M – Complete Streets D.

Protect screeded Setting Bed Sand from being disturbed by either pedestrian or vehicular traffic. b. Screed only the area which can be covered by pavers in one day. c. Do not use Setting Bed Sand material to fill depressions greater in the base surface. 2. Keep moisture content constant and density loose and constant until Concrete Pavers are set and compacted. 3. Screed the Setting Bed Sand using either an approved mechanical spreader (e.g.: an asphalt paver) or by the use of screed rails and boards. 4. Carefully maintain spread Setting Bed Sand in a loose condition, and protected against incidental compaction, both prior to and following screeding. Loosen any incidentally compacted sand or screeded sand left overnight before further paving units are placed. 5. Fully protect screed Setting Bed Sand against incidental compaction, including compaction by rain. Remove any screeded Setting Bed Sand that is incidentally compacted prior to laying of the paving units. Do not permit either pedestrian or vehicular traffic on the screeded Setting Bed Sand. 6. Inspect the Setting Bed Sand course prior to commencing the placement of the Concrete Pavers. Acceptance of the Setting Bed Sand occurs with the initiation of Concrete Paver placement. C. Concrete Pavers 1. Replace Concrete Pavers with chips, cracks, voids, discolorations, and other defects that might be visible in finished work. 2. Mix Concrete Pavers from a minimum of three (3) bundles simultaneously drawing the paver vertically rather than horizontally, as they are placed, to produce uniform blend of colors and textures. (Color variation occurs with all concrete products. This phenomenon is influenced by a variety of factors, e.g. moisture content, curing conditions, different aggregates and, most commonly, from different production runs. By installing from a minimum of three (3) bundles simultaneously, variation in color is dispersed and blended throughout the project). 3. Exercise care in handling face mix concrete pavers to prevent surfaces from contacting backs or edges of other units. 62 City of Davenport, Iowa Division 7 – Streets and Related Work SUDAS Supplemental Specifications Section 7035.A – Streetscape Improvements: Concrete Unit Pavers 4.

(15 m) from string lines. 10. Fill gaps between units or at edges of the paved area that exceed 3/8 inch (10 mm) with pieces cut to fit from full-size unit pavers. 11. Prevent all traffic on installed Concrete Pavers until Joint Sand has been vibrated into joints. Keep skid steer and forklift equipment off newly laid Concrete Pavers. 12. Vibrate Concrete Pavers into leveling course with a low-amplitude plate vibrator capable of a to 5000-lbf (22-kN) compaction force at 80 to 90 Hz. Perform at least three passes across paving with vibrator. Vibrate under the following conditions: a. After edge pavers are installed and there is a completed surface or before surface is exposed to rain. b. Compact installed Concrete Pavers to within 6 feet (2 meters) of the laying face before ending each day's work. Cover Concrete Pavers that have not been compacted and leveling course on which pavers have not been placed, with non-staining plastic sheets to prevent Setting Bed Sand from becoming disturbed. 13. Protect face mix Concrete Paver surface from scuffing during compaction by utilizing a urethane pad. 14. Remove any cracked or structurally damaged Concrete Pavers and replace with new units prior to installing Joint Sand material. D. Joint Sand 1. Provide, spread and sweep dry Joint Sand into joints immediately after vibrating pavers into Setting Bed Sand course until full.

If more than 10 percent of any 2,000-foot section of marking fails during this 90-day period for any reason except abrasion at private entrances or within intersections, repair or replace those sections, at the Contractor’s expense, prior to final acceptance. Transverse lines and symbols will be evaluated individually. a. Failure of the marking will be rated on the basis of the percentage of material remaining on the pavement at the end of the 90-day period. This will be the percentage of the area in which the substrate is not exposed. ADD the Following: L. Thermoplastic Markings: 1. Extrude or hot-spray the thermoplastic marking material onto the pavement surface. a. Ensure that the pavement marking have well defined edges and are free of waviness, b. Check that they have a minimum thickness of 90 mils if extruded or 60 mils if hot-sprayed 1) The thickness will be measured as a wet film, except the Engineer may measure cured film by placing a tape or other bond breaker prior to placing the thermoplastic material then removing a section of cured line and measuring thickness. 2. Temperature Limitations. a. Place the thermoplastic markings when the pavement surface is at least 55°F and the ambient temperature is 49°F and rising. Determine the pavement surface temperature and air temperature before the start of each day of marking operation and at any other time deemed necessary by the Engineer. b. Apply the thermoplastic at a temperature of 400-425°F, depending on the manufacturer’s recommendation. c. Check the temperature of the thermoplastic material at the point of deposition with a calibrated thermometer at: 100 City of Davenport, Iowa Division 8 SUDAS Supplemental Specifications Section 8020 – Pavement Markings 1) the beginning of each day’s marking, 2) after material is added to the dispensing device, 3) after delays in the marking operation, and 4) any time deemed necessary by the Engineer. d. Do not heat alkyd thermoplastic material above 435°F. e. Do not heat hydrocarbon thermoplastic material above 450°F. f. Only heat the quantity of thermoplastic that can be used within 4 hours. g. Do not heat any thermoplastic material for more than 4 hours at the maximum application temperature, including initial heating. h. Do not reheat more than two times. i. Materials subjected to the above conditions will be rejected. 3. Check adhesion to the pavement surface with a stiff putty knife or similar instrument. The marking should not be removed from a concrete surface. The marking may be removed from a bituminous surface; however, the bituminous substrate will be stuck to the thermoplastic material. 4. If the thermoplastic line does not provide initial nighttime reflectivity, or if the marking does not have the required minimum thickness, a. Grind away the surface of the deficient portion of the marking to reduce the average thickness to 50 mils or less. b. Apply additional thermoplastic material to a thickness of at least 125 mils and provide a uniformly reflective surface. c. If the markings do not comply with the specifications for any other reason, the Engineer may require complete removal or correction at the Contractor’s expense. Corrective work will be at Contractor’s expense. 5. Primer Application. a. Apply a primer to bituminous surfaces over 2 months old and all concrete surfaces. Primer is not required on bituminous surfaces less than 2 months old unless recommended by the manufacturer of the thermoplastic material. b. Apply and cure in accordance with the recommendations of the manufacturer of the thermoplastic material. 6. Glass Bead Application. a. Mechanically deposit the drop on glass beads on the molten thermoplastic line immediately after placement of the thermoplastic at a rate of 8 to 10 pounds per 100 square feet of line. b. Embed the beads into the strip surface to a depth of 50% - 60% of the bead diameter. c. Ensure the beads are applied uniformly across the entire line. d. Ensure that the beads adhere to the cured thermoplastic or all marking operations shall cease until corrections are made. ADD the following: 3.03 Sampling and Testing 101 City of Davenport, Iowa Division 8 SUDAS Supplemental Specifications Section 8020 – Pavement Markings C. General: The Engineer shall have free access to the material and be extended every facility for the purpose of inspection. The Engineer reserves the right to sample at the point of manufacture, at intermediate points of storage, or at destination. D. Thickness: Perform periodic spot checks of thermoplastic material to verify that the required thickness has been attained. Random spot checks of the thermoplastic thickness will be made by the Engineer to ensure conformance with the required criteria. Suggested spot check procedures include the following: 1. Wet: Thickness can be field tested immediately after the thermoplastic marking is applied by inserting a thin, graduated machinist rule or similar instrument into the molten thermoplastic to the depth of the pavement surface. The thickness is then determined visually by noting on the scale the depth of the penetration or coating of the instrument. 2. Dried: Thickness can be field tested by placing a small flat of metal with a known thickness immediately ahead of the striping apparatus. After striping, remove the sample and use a suitable measuring device, such as a caliper or micrometer, to determine the thickness of the dried marking E. Thermoplastic Material: The Engineer reserves the right to test materials in accordance with ASTM D4960 Test Method for Evaluation of Color for Thermoplastic Traffic Marking Materials, AASHTO T250 Standard Method of Test for Thermoplastic Traffic Line Material, and AASHTO M 249-98 White and Yellow Reflective Thermoplastic Striping Material (Solid Form). Cost for these tests will be paid for by the Jurisdiction; however, if any of them fail, the Contractor is liable for the cost. F. Glass beads: Test glass beads in accordance with the procedures listed in standard specification 4184.03. The Engineer will determine the location and frequency of sampling. 102 City of Davenport, Iowa Division 8 SUDAS Supplemental Specifications Section 8030 – Temporary Traffic Control Section 8030 – Temporary Traffic Control PART 1 – GENERAL 1.07 Special Requirements ADD the following: C.

Seeding Establishment & Maintenance Period: 1. When included as a separate bid item, the Seeding Establishment & Maintenance Period for Prairie and/or Wetland seeding shall include the provisions identified in 107  City of Davenport, Iowa Division 9 SUDAS Supplemental Specifications Section 9010 - Seeding 9010, 3.10, A. and B, with a minimum 3-year warranty period. In addition, the following: a. A more intense maintenance program is required for a period of at least 3 years, to support full establishment of desired vegetation and prevent growth of invasive species (especially cattails and volunteer woody growth). It is recommended that these activities should be completed by personnel with experience (3 years or more preferred) in performing maintenance of native vegetation. b. For wetland areas, managing water levels through the water control structure provides a moist soil environment for the existing seed bank to germinate without the presence of standing water. Once the plants germinate and are actively growing, water levels can be slowly returned to normal. Most emergent plants will reproduce through the roots when submerged. If the plants begin to die out another drawdown may be needed in the future. Mowing areas will also depend on water levels and soil saturation. c. Maintenance associated with the establishment period shall be as follows: Establishment-First Year Schedule If there are erosion concerns, install erosion control blanket or place straw over Immediately after seeding. seeding If it doesn’t rain, water seed. Water enough to moisten surrounding soil, but Spring until water lightly so seedlings are not dislodged. As seedlings emerge and develop, established irrigate less frequently but enough to prevent drought stress. Persistent attention to weed control is required. Keep weeds cut back to a One to two times per height of 6 inches when they reach a height of 12 inches (if accessible). The first month depending on mowing if done early enough (early May) can be to a height of 4 inches. rainfall, not after Aug 1 Otherwise, do not cut back less than 8 inches. Flat type mowers work best because they chop weeds and prevent clippings from smothering small seedings. Weed-trimmers are excellent for smaller areas. Rotary or bar-sickle mowers may be used but can smother seedlings because they do not chop weeds. Hand weeding may also be necessary. Do not mow the first year’s growth after August 1. This will protect young plants over winter. If a cover crop was used, it should also be cut during the first season. Mow 1 time per month cover crop when weeds reach 6 inches tall. depending on rainfall Use systemic herbicide treatment of areas larger than 20 square feet where Only if needed weeds are the dominant plant material. Reseeding will need to occur in these areas. Follow manufacturer’s instructions on any herbicide application. Do not spray any broadleaf chemicals in the first year where native wetland First year seedlings are growing. Broadleaf chemicals will kill forbs and damage or kill grasses. 108  City of Davenport, Iowa Division 9 SUDAS Supplemental Specifications Section 9010 - Seeding Hand-treat with herbicide using a cotton glove placed on the outside of a Only if needed protective rubber glove. Soak the cotton glove in herbicide (such as “Roundup”) and apply to the leaves and stems of the weed or woody species without touching adjacent desirable plants. This is best done on a calm, cool day, so that the herbicide does not volatilize and drift onto nearby plants. Remove the above- ground portion of previously treated dead or dying weeds and woody species from planting areas. Follow manufacturer’s instructions on any herbicide application.

Additional Considerations – Native Stands: 1. Follow USDA-NRCS and local fire department guidance development for prescribed burn permitting, scheduling, and implementation. 2. Mowing should not be completed during nesting seasons of ground nesting birds, if present. If mowing begins and ground nesting birds are discovered, cease mowing. 3. Marestail will often show up in the second year. It looks worse than it is, but its growth pattern still allows light through the canopy. Marestail will naturally decline as the prairie establishes. 4. Mow Canada thistle patches at bud stage (late June to early July). The prairie will often out-compete thistles with timely mowing. 5. Do not mow after weeds are 4-6 feet high. At that point you are better off not to mow. Doing so will put a mat of material on the new emerging seedlings. 6. Spot mowing may be needed in areas where weed pressure is still prevalent in year two. Giant Ragweed can be very persistent. Musk thistles may still be prevalent but will be out-competed by the prairie long-term. ADD D.

Notice is hereby given that neither Landlord nor Landlord’s interest in the Leased Premises shall be liable or responsible to persons who furnish material or labor for or in connection with such work. Tenant shall give Landlord’s Senior Manager notice of any work greater than $5,000 performed on the premises prior to work beginning, emergencies excepted. 12. ABANDONMENT Tenant shall not vacate or abandon the Leased Premises at any time during the term of this Lease; if Tenant shall abandon, vacate or surrender the Leased Premises or be dispossessed by process of law, or otherwise, any personal property belonging to the Tenant and left on the Leased Premises shall be deemed to be abandoned, at the option of the Landlord and disposed of as Landlord sees fit without liability. Tenant shall not be considered to have vacated or abandoned the Leased Premises caused by reasons beyond Tenant’s control (casualty, strikes, and acts of God). 13. SIGNS AND ADVERTISING MATERIALS Tenant acknowledges that Signage Restrictions apply to the demised area. A plan for proposed signage shall be presented to the Landlord for review and approval before installation. 14. EXTERIOR LIGHTING Tenant shall not install any exterior lighting on the Leased Premises unless and until Landlord shall have approved in writing the design, type, kind and location of the lighting to be installed. 15.

Tenant shall pay all charges for telephone service, trash, garbage, and rubbish removal used by Tenant. Any security deposit or connection charges required by any utility company to furnish services to Tenant shall be paid by Tenant. Landlord shall be responsible for water and sewer. 16. ENTRY AND INSPECTION Upon prior notice to Tenant, Tenant shall permit Landlord and Landlord’s agent to enter into and upon the Leased Premises at all reasonable times, acceptable to Tenant, for the purpose of inspecting the same or for the purpose of maintaining the building in which said Leased Premises are situated, or for the purpose of making repairs, alterations or additions to any other portion of said building. The Landlord shall have the right to advertise and show the property to prospective users of the Leased Premises during the final ninety (90) days of the lease term. 17. MAINTENANCE, DAMAGE, AND DESTRUCTION OF LEASED PREMISES A. All damages to the Leased Premises or to its fixtures, glass, appurtenance, and equipment caused by Tenant, its agents, contractors, employees, guests, licensees, or invitees shall be repaired, restored, or replaced promptly by Tenant, at its sole cost and expense, and shall be in quality and class equal to the original work. B. For any reason other than those in Paragraph 16A, Landlord agrees at its cost and expense to maintain the roof, walls and foundation of the Leased Premises and building in reasonably good order and condition and to make all necessary repairs and replacements to the building as it relates to the Leased Premises, interior and exterior, structural and non-structural, ordinary and extraordinary, foreseen and unforeseen and will accomplish such repairs promptly with good materials, in a good and workman like manner and in compliance with all applicable laws of all governmental authorities having jurisdiction and in a style, character and quality conforming to existing construction. These repairs and replacements include, sidewalk, windows, driveways, service area, curbs and parking areas in and around the building, the water, sewage, gas, electrical lines and installations servicing the building and the Leased Premises, heating and air conditioning system in the building insofar as it affects the Leased Premises and the common areas, all repairs and restoration made necessary by fire or other casualty and all required repairs and replacements of improvements to the Leased Premises constructed initially by or under control or supervision of Landlord. The landlord is only responsible for bringing the utilities to the Leased Premises. If the Landlord fails to perform obligations under this Lease that create a condition that interferes substantially with regular use, and consequently, the Tenant is compelled to discontinue business in the Leased Premises in whole or in part, rental shall be proportionally abated. If, for conditions interfering substantially with regular use, the Landlord defaults for more than fifteen (15) days, after written notice by Tenant, Tenant shall have the right but not be obligated to remedy such default. All such sums expended, or obligations incurred by Tenant in connection with the foregoing, shall be paid by the Landlord to Tenant upon demand. If the Landlord fails to reimburse the Tenant within 30 days, the Tenant may, in addition to any other right or remedy that the Tenant may have, deduct such amount from the next month’s rent or rentals. Rather than remedy such a default by engaging in repair work, Tenant may terminate this Lease. This subparagraph shall not be interpreted to mean that Landlord is responsible for repairing or replacing Tenant’s build-out of the space or Tenant’s furnishings, fixtures, and equipment. 18. ASSIGNMENT AND SUBLETTING Tenant shall not assign this Lease, or any interest therein, and shall not sublet the Leased Premises or any part thereof, or any right or privilege appurtenant thereto, or permit any other person (the agent and servants of Tenant excepted) to occupy or use the Leased Premises, or any portion thereof, without first obtaining the written consent of the Landlord. Such consent shall not be unreasonably withheld if the proposed assignee is of equal financial standing and responsibility to give reasonable assurance of the payment of all rents and other amounts reserved in the Lease and of compliance with all terms, covenants, and conditions of this Lease and provides proof of insurance with the city as an additional insured. Consent by Landlord to one assignment, subletting, occupation, or use by another person shall not be deemed to be consent to any subsequent assignment, subletting, occupation, or use by another person. Consent to an assignment shall not release the original named Tenant from liability which has accrued or occurred before the date of assignment. If Landlord does not release Tenant from liability, Landlord shall give Tenant notice of default and an opportunity to cure the same. Any assignment or subletting without the prior written consent of the Landlord shall be void, and shall, at the option of the Landlord, terminate this Lease. Neither this Lease nor any interest therein shall be assignable, as to the interest of Tenant, by operation of law without the prior written consent of Landlord. Landlord shall give Tenant prior notice of the assignment of this Lease and/or an interest of Landlord therein. 19. DEFAULT, RE-ENTRY REMEDIES If the Tenant shall fail to pay any part of the rent herein provided or any other sum required by this Lease to be paid to Landlord at the times or in the manner provided, or if default shall be made in any of the other covenants or conditions on its part agreed to be performed, and such failure to perform other covenants shall continue for thirty (30) days, unless another time is specified in this Lease, after written notice thereof from Landlord to Tenant, then Landlord, besides other rights or remedies it may have, shall have the immediate right of re-entry and may remove all persons and property from the Leased Premises, without liability to any person for damages sustained by reason of such removal. 20. DEFAULT COSTS AND ATTORNEY FEES If the Tenant shall fail to pay any part of the rent herein provided or any other sum required by this Lease to be paid to Landlord at the times or in the manner provided, or if default shall be made in any of the other covenants or conditions on its part agreed to be performed. The Tenant shall be responsible for payment of all reasonable costs and attorney fees (to be calculated at a rate of $175 per hour for work performed by the Landlord’s staff attorneys) of the Landlord that result from the Landlord pursuing its rights and remedies. If the Landlord shall fail to meet the obligations of this agreement herein provided or any other sum required by this Lease at the times or in the manner provided, or if default shall be made in any or the other covenants or conditions on its part agreed to be performed, then Landlord shall be responsible for payment of all reasonable costs and attorney fees (to be calculated at a rate of $175 per hour for work performed by the Tenant’s staff attorneys) of Tenant that result from Tenant’s pursing its rights and remedies. 21. SALE OF LEASED PREMISES BY LANDLORD In the event of any sale of the Leased Premises or assignment of this Lease by the Landlord, Landlord shall give Tenant prior notice of any such sale or assignment. Landlord shall be relieved of liability under the Lease only if the new landlord agrees to the Lease and not to disturb Tenant. 22. REIMBURSEMENT A. Tenant shall perform all covenants and terms herein contained to be performed by Tenant at Tenant’s expense, and if Landlord shall pay any sum of money or do any act which requires the payment of money by reason of the failure, neglect or refusal of Tenant to perform such covenant or term, the sum or sums of money so paid by Landlord shall be considered as additional rental and shall be payable by Tenant to Landlord on the first of the month next succeeding such payment, together with interest at the maximum rate permitted by law from the date of payment. B. Landlord shall conduct all covenants and terms herein contained to be performed by Landlord at Landlord’s expense. If Tenant shall pay any sum of money or do any act which requires the payment of money by reason of the failure, neglect or refusal of Landlord to perform such covenant or term after written notice by Tenant, the sum or sums of money so paid by Tenant shall be considered as rental and shall be deducted by Tenant from the rent on the first of the monthly next succeeding such payment. 23. WAIVER No covenant, term, or condition of this Lease shall be waived except by written waiver of Landlord. The forbearance or indulgence by Landlord in any regard whatsoever shall not constitute a waiver of the covenant, term, or condition to be performed by Tenant to which the same shall apply. Until complete performance by Tenant of such covenant, term or condition, Landlord shall be entitled to invoke any remedy available under this Lease or by law despite such forbearance or indulgence. The waiver by Landlord of any breach, term, covenant, or condition hereof shall apply to and be limited to the specific instance involved and shall not be deemed to apply to any other instance or to any subsequent breach of the same or any other term, covenant, or condition hereof. 24.

It shall in no way be affected, impaired, or invalidated thereby. 26. EMINENT DOMAIN A. If the whole of the Leased Premises shall be acquired or condemned by eminent domain for any public or quasi-public use or purpose, then the term of this Lease shall cease and terminate as of the date of title vesting in such proceeding. All rentals shall be paid up to that date, and except for the improvement balance credit, Tenant shall have no claim against Landlord for the value of any unexpired term of this Lease. B. If any part of the Lease Premises shall be acquired or condemned by eminent domain for any public or quasi-public use or purpose, and if such partial taking or condemnation shall render the Leased Premises unsuitable for the business of the Tenant which shall be at Tenant’s reasonable discretion, then the term of this Lease shall cease and terminate as of the date of title vesting reasonable discretion, then the term of this Lease shall cease and terminate as of the date of title vesting in such proceeding and Tenant shall have no claim against Landlord for the value of any unexpired term of this Lease.

In the event of any condemnation or taking as hereinbefore provided, whether whole or partial, Landlord and Tenant shall each be entitled to receive and retain such separate awards and portions of lump sum awards as may be allocated to their respective interests in any condemnation proceeding.

Nothing herein shall be construed to prevent Tenant from prosecuting any claim directly against the condemning authority in such condemnation proceedings for loss of business, depreciation to, damage to, or cost of removal of, or for value of stock, trade fixtures, furniture, and other personal property belonging to Tenant. 27. CUMULATIVE RIGHTS The various rights, powers, options, elections, and remedies of any party provided in this Agreement shall be construed as cumulative. Not one of them is exclusive of the others or exclusive of any rights, remedies, or priorities allowed either party by law, and shall in no way affect or impair the right of any party to pursue any other equitable or legal remedy to which any party may be entitled as long as any default remains in any way unremedied, unsatisfied, or undercharged. 28.
