ATTACHMENT 'B'

REVOCABLE LICENSE AGREEMENT This Revocable License Agreement (“Agreement”) is entered into by and between The Regents of the University of Colorado, a body corporate, on behalf of the University of Colorado Boulder (the “University”), and the City of Boulder, a Colorado home rule city (the "City"). Recitals Whereas, the University wishes to construct and extend underground chilled water lines, which are more particularly described in Exhibit B, portions of which will encroach upon the City’s Folsom Street public right-of-way (“ROW”), from Main Campus of the University to the North Boulder Creek area of the University (the “Project”). Whereas, the University requires a revocable license agreement to complete the Project and to access and maintain the underground chilled water lines into perpetuity. Whereas, the City wishes to enter into an Agreement with the University to allow the University to complete the Project and to provide a revocable license to the University for purposes of allowing the University to access the Property to maintain the underground chilled water lines for twenty years. Agreement NOW THEREFORE, in consideration of the mutual promises made herein, the University and the City enter into this Agreement as follows: 1. Term. The term of this Agreement shall be twenty years (“Term”). The effective date of this Agreement will be the last date that the authorized University officer signs the Agreement. Upon termination, the University agrees to restore the ROW to its original condition unless a new permit has been applied for or is issued. 2. Grant of Revocable License. The City hereby grants the University a revocable license (“License”) to allow the University to access City property depicted in Exhibit A (“Property”) for purposes of completing the Project and maintaining the University’s underground chilled water lines. Exhibit A is attached, incorporated by reference, and made a part of this Agreement. On the Property, the Project shall be constructed and maintained consistent with the plans attached in Exhibit B. 3. Restoration and Repair of Property. The University agrees that upon completion of the Project, and after any maintenance of the underground chilled water lines, it will remove any equipment or personal property placed on the Property in accordance with regular, accepted industry practices and applicable laws and regulations, and will restore any portion of the Property affected by the University’s use under the License to a condition equivalent to its present condition. The City will give notice to the University in a reasonable and timely manner of any condition that the City discovers for which the University is responsible under this Agreement, and the University will remedy any defect in a reasonable and timely manner. 4. Revocation and Removal. The City may elect to revoke the License and this Agreement by providing written notice to the University of such election. The notice of 1

ATTACHMENT 'B'

revocation by the City shall be delivered to the University not less than one hundred and eighty (180) days prior to the effective date of revocation. The decision to revoke may be made whenever the City, in its sole discretion, determines to revoke pursuant to Section 115 of the Boulder Revised Charter. All releases shall survive revocation. The University shall remove, at its expense, the underground water chiller lines and associated encroachments within thirty days of revocation. In the event that the University does not remove the encroachment(s) within thirty days, the University agrees to reimburse the City for the costs of removal. 5. Relocation. In the event that the City, pursuant to section 8-5-14 “Relocation of Facilities” of the Boulder Revised Code, as the same may be amended from time to time, decides to relocate any segment of the water chiller lines, the University agrees to be responsible for reasonable expenses associated with such relocation. In the event of any such relocation, the City agrees to provide the University with ninety (90) days’ notice in writing unless failure to relocate poses a threat to health, safety, or welfare of the public or individuals as determined by the City in which case the City will have the right to move the water chiller lines without such notice or with lesser notice. It is the intent of the City to act in good faith and not require relocation unless it determines there is a public safety or some other bona fide purpose for such relocation. Following relocation, all affected property shall be restored to, at a minimum, the condition which existed prior to construction at the University's expense. 6. Impact on the City. The University’s use of the License will be conducted in such a manner as to minimize any disruption or interference with the City’s operations. All University activities will be coordinated between CU Boulder’s department of Facilities Management and the City’s Planning & Development Services (“P&DS”) department. The University will communicate the following information to P&DS: Construction schedule; instrument deployment schedule; and any other construction-related information requested by the City. This Agreement does not control or limit any improvements the City wishes to make on, or use it chooses to make of, the Property. 7. Permits, Approvals, Codes and Standards. The University will comply with all applicable City standards and codes in its use of the Property or pursuant to this Agreement. The University will be responsible for acquiring appropriate City permits to complete the Project, which City permits shall not be unreasonably withheld. 8. Insurance. Prior to execution of this Agreement, the University shall submit to the City insurance policies or Certificates of Insurance as evidence of compliance with the provisions of this paragraph and subject to approval by the City. The University shall, at University’s sole expense, procure and maintain or cause to be procured and maintained with insurers approved by the City, who any licensed to do business in Colorado and have an AM Best rating of at least A-VI, worker’s insurance as required by state law and a comprehensive general liability insurance policy with minimum limits of $1 million per occurrence and a $2 million aggregate. The University agrees that the above stated policy limits shall be raised to meet any additional coverage necessitated by amendments to the Colorado Governmental Immunity Act that may expose the City to judgments greater than the insurance coverage required in this License. 2

ATTACHMENT 'B'

This policy shall be written on a primary basis, non-contributory with any other insurance coverage and/or self-insurance carried by the City. This policy shall be maintained in full force and effect for the duration of the License. The University or University's insurance broker shall notify the City of any cancellation or reduction in coverage or limits of any insurance policy within seven days of receipt of insurers' notification to that effect. The University shall obtain and submit proof of substitute insurance in the event of expiration or cancellation of coverage and shall provide the City with an updated Certificate of Insurance annually. Additional Insurance Requirements: a. All insurers must be licensed or approved to do business within the State of Colorado. b. The Certificate Holder shall be identified as: City of Boulder, 1777 Broadway, P.O. Box 791, Boulder, CO 80306. c. A Separation of Insureds Clause must be included in general liability policies. d. The University shall advise the City in the event any general aggregate or other aggregate limits are reduced below the required per occurrence limit. At its own expense, University will reinstate the aggregate limits to comply with the minimum requirements and shall furnish to the City a new certificate of insurance showing such coverage is in force. e. The City and University shall cooperate with each other in the collection of any insurance proceeds that may be payable in the event of any loss, including the execution and delivery of any proof of loss or other actions required to affect recovery. f. The University shall not be relieved of any liability, claims, demands, or other obligations assumed pursuant to this License by reason of its failure to procure or maintain insurance or by reason of its failure to procure or maintain insurance in sufficient amounts, durations or types. 9. Environmental Matters. The University will not cause or permit the storage, treatment or disposal of any Hazardous Materials in, on, or about any part of the Property by the University, its agents, employees or contractors in violation of any state or federal Environmental Law. The University will not permit the Property to be used or operated in a manner that may cause the Property or any part of the Property to be contaminated by any Hazardous Materials in violation of any Environmental Laws. Through the duration of the Project and for any subsequent maintenance and use of the water chiller lines, the University will follow the requirements of the City for protection of streams, wetlands, and bodies of water, and other similar standards, as found in 9-3-9 of the Boulder Revised Code, for or about any part of the Property. The University will notify the City of any and all enforcement, cleanup, remedial, removal, or other governmental or enforcement cleanup or other governmental or regulatory actions instituted, completed or threatened pursuant to any Environmental Laws relating to any Hazardous Materials affecting any part of the Property. 3

ATTACHMENT 'B'

The University will notify the City of all claims made or threatened by any third party against the City relating to damage, contribution, cost recovery, compensation, loss or injury resulting from any Hazardous Materials on or about the Property or any part of the Property as a result of the University’s use of the Property. The University holds the City harmless from the same and subject to the limitations of the Colorado Governmental Immunity Act, as further articulated in Section 10 of this Agreement. "Hazardous Materials" means asbestos, explosives, radioactive materials, hazardous waste, hazardous substances, or hazardous materials including, without limitation, substances defined as "hazardous substances" in the Comprehensive Environmental Response Compensation Liability Act of 1980, as amended, 42 U.S.C. section 9601-9657 ("CERCLA"); the Hazardous Material Transportation Act of 1975, 49 U.S.C. section 1801-1812; the Resource Conservation Recovery Acts of 1976, 42 U.S.C. section 6901-6987; the Occupational Safety and Health Act of 1970, 29 U.S.C. 651 et seq., or any other federal, state or local statute, law, ordinance, code, rule, regulation, order or decree regulating, relating to, or imposing liability or standards of conduct concerning hazardous materials, wastes or substances now or at any time hereinafter in effect (collectively, "Environmental Laws"). "Hazardous Waste" means hazardous waste as defined under the Resource Conservation Recovery Act of 1976, 42 U.S.C. section 6901-6987. 9. Status and Assignment. This Agreement constitutes a mere license. It does not create an interest in land. It is not coupled with an interest. No subsequent act or course of dealing shall serve to alter the status of the Agreement except by written amendment duly executed by the authorized agents of the City and the University. This Agreement is not assignable. 10. Governmental Immunity. It is specifically understood and agreed that nothing contained in this Agreement shall be construed as an express or implied waiver by the University or the City of its governmental immunity or of the governmental immunity of the State of Colorado, as an express or implied acceptance by University or the City of liabilities arising as a result of actions which lie in tort or could lie in tort in excess of the liabilities allowable under the Colorado Governmental Immunity Act, C.R.S. §§ 24-10-101 et seq., as a pledge of the full faith and credit of the State of Colorado, or as the assumption by the University or the City of a debt, contract or liability in violation of Article XI, Section 1, of the Constitution of the State of Colorado. 11. Liability. Each Party shall be responsible for any claims, damages, losses, or liabilities arising out of the acts or omissions of its own officers, employees, agents, or contractors in the performance of this Agreement. Nothing in this Agreement shall be construed to require either Party to assume responsibility for the acts or omissions of the other Party, or of the other Party’s officers, employees, agents, or contractors. This provision is intended solely to allocate responsibility between the Parties in accordance with applicable law and does not constitute an agreement to indemnify, hold harmless, or otherwise assume liability for acts or omissions of the other Party.

ATTACHMENT 'B' 12. Colorado Law Applies. This Agreement shall be governed, construed, performed and enforced in accordance with the laws of the State of Colorado. IN WITNESS WHEREOF, the University and the City have caused this Agreement to be executed by their duly authorized representatives.
