or liabilities that may be asserted or claimed by any person, firm, entity, corporation, political
subdivision, or other organization arising out of or in connection with the work, operation, or
activities of CONTRACTOR, its agents, employees, subcontractors or invitees provided for
herein, whether or not there is concurrent passive negligence on the part of CITY. In connection
therewith:
a. CONTRACTOR will defend any action or actions filed in connection with
any such claims, damages, penalties, obligations or liabilities and will pay
all costs and expenses, including attorneys' fees, expert fees and costs

percentage of the liability involved, the obligation of Contractor will be for that entire portion or
percentage of liability not attributable to the active negligence of CITY.
So much of the money due to CONTRACTOR under and by virtue of the contract as shall

such actions or claims for damages as aforesaid.

remedies which Indemnitees may have under the law.

insurance coverage which may have been required under this AGREEMENT or any additional
insured endorsements which may extend to Indemnitees.

waives all rights of subrogation and contribution against the Indemnitees, while acting within the
scope of their duties, from all claims, losses and liabilities arising out of or incident to activities
or operations performed by or on behalf of the CONTRACTOR regardless of any prior,
concurrent, or subsequent passive negligence by the Indemnitees.

Payment Account, which is the sole source of funds available for payment of the contract sum
set forth in Section 3 of this AGREEMENT. CONTRACTOR understands and agrees that
CONTRACTOR will be paid only from this special fund and if for any reason this fund is not
sufficient to pay CONTRACTOR, CONTRACTOR will not be entitled to payment. The availability
of money in this fund, and CITY's ability to draw from this fund, are conditions precedent to
CITY's obligation to make payments to CONTRACTOR.

Code §9204, shall be submitted in accordance with Section 9204 and shall contain a sufficient
description of the claim, the basis therefore and documentation in support of the claim. The claim
