EXHIBIT B-41- • This indemnity shall survive the expiration or termination of the Agreement and shall remain in effect until such time as an action on account of any matter covered by such indemnity is barred by applicable statute of limitations. Contractor’s indemnification obligation under these Landlord General Terms and Conditions ("General Conditions") shall apply regardless of the passive negligence of Indemnitees and regardless of whether liability without fault is imposed or sought to be imposed on Indemnitees, except to the extent that such indemnity is void or otherwise unenforceable under applicable law in effect on or validly retroactive to the date of the Agreement, and except where such Liabilities are the result of the sole or active negligence or willful misconduct of Indemnitees or independent contractors who are directly responsible to Indemnitees other than a Contractor Party. • This indemnity shall not be construed to negate, abridge or otherwise reduce any other right or obligation of indemnity which would otherwise exist in favor of the Indemnitees under the Agreement, at law or in equity, as to any part or person described in these Landlord General Conditions or otherwise. Such indemnification shall extend to Liabilities which accrue or relate to events which occur after completion of the Work as well as during the Work’s progress. Nothing herein shall be deemed to abridge the rights, if any, of Owner or any of the other Indemnitees to seek contribution where appropriate. For the purposes of these Landlord General Terms and Conditions, Owner shall be deemed to mean KRC Entity. • As used herein, the term "Contractor Party" means Contractor, Contractor's Subcontractors of every tier, consultants and/or material suppliers and their respective employees, agents and/or representatives. • In connection with any and all Claims against the Indemnitees and by any employee of the Contractor, any Subcontractor, anyone directly or indirectly employed by any of them or anyone for whose acts any of them may be liable, the indemnification obligation under these Landlord General Conditions shall not be limited in any way by any limitation on the amount or type of damages, compensation or benefits payable by or for the Contractor or any Subcontractor under worker's or workmen's compensation acts, disability benefit acts or other employee benefit acts. • Indemnified Liabilities under these Landlord General Conditions shall include, without limitation: (1) injury or damage consequent upon the failure of or use or misuse by Contractor, its Subcontractor, agents, and all other kinds of items of equipment, whether or not the same be owned, furnished or loaned by Owner and (2) time expended by the Indemnitee and its employees at their usual rates plus all costs for reproduction of documents. EXHIBIT B-42- • The Contractor’s indemnity obligations under these Landlord General Conditions shall, but not by way of limitation, specifically include all claims and judgments which may be made against the Indemnitees under any “safe place to work” or similar-type statute, similar laws of a state or other governmental body having jurisdiction, and against claims and judgments arising from violation of public ordinances and requirements of governing authorities due to the Contractor’s or Subcontractor’s method of execution of the Work. The Contractor's indemnity obligations shall also specifically include, without limitation, all fines, penalties, damages, liability, costs, expenses (including, without limitation, reasonable attorneys' fees), and punitive damages (if any) arising out of, or in connection with, any (i) violation or failure to comply with any law, statute, ordinance, rule regulation, code, or requirement of a public authority that bears upon the performance of the Work by the Contractor, a Subcontractor, or any person or entity for whom either is responsible, (ii) means, methods, procedures techniques, or sequences of execution or performance of the Work, and (iii) failure to secure and pay for permits, fees, approvals, licenses, and inspections as required under the Contract Documents, or any violation of any permit or other approval of a public authority applicable to do the Work, by the Contractor, a Subcontractor, or any person or entity for whom either is responsible. • Except as otherwise expressly set forth herein, the indemnification obligations of the Contractor under the Agreement shall be limited only to the extent required by the laws of the State in which the Project is located. • All fees, costs and expenses to be paid by Contractor as indemnitor hereunder shall be made on a "paid as incurred" basis within thirty (30) days of the indemnitor’s receipt of a statement or invoice therefor. Should the indemnitor object to any such fees, costs or expenses, the indemnitor shall nevertheless pay such fees, costs and expenses within such thirty (30) days which payment, if expressly stated in writing at the time of such payment to be "under protest", shall not prejudice the indemnitor’s right to subsequently object to such fee, cost or expense paid under protest. • Contractor’s duty to defend Indemnitees is entirely separate from, independent of and free-standing of Contractor’s duty to indemnify Indemnitees, including without limitation, the defense of Indemnitees against claims for which Indemnitees (or any of them) may be strictly liable and applies whether the issue of Contractor’s negligence, breach of contract or other fault or obligation has been determined and whether Indemnitees (or any of them) have paid any sums, or incurred any detriment, EXHIBIT B-43- arising out of or resulting directly or indirectly from Contractor’s performance of the Work. It is the parties’ intention that Indemnitees (or any of them) shall be entitled to obtain summary adjudication of Contractor’s duty to defend Indemnitees at any stage of any action or suit within the scope of these Landlord General Conditions. Indemnitees shall be entitled to recover their reasonable attorneys’ fees and costs incurred in enforcing the provisions of these Landlord General Conditions. Payment to Contractor by any Indemnitee shall not be a condition precedent to enforcing such parties’ right to indemnity. The contractual right of indemnification provided to Indemnitees hereunder shall be cumulative to all rights of equitable indemnity to which the Indemnitees may otherwise be entitled; provided, however, that reservation of the right of equitable indemnity shall not apply to reduce or decrease any rights of indemnity provided to Indemnitees pursuant to the Contract.
