policy endorsements. All certificates and endorsements and copies of the Declarations &

specifications, at any time. City of Stockton reserves the right to modify these requirements, including
limits, based on the nature of the risk, prior experience, insurer, coverage, or other special

said Contractor may acquire against the City of Stockton by virtue of the payment of any loss under
such insurance. Contractor agrees to obtain any endorsement that may be necessary to affect this
waiver of subrogation and provide a copy to the City of Stockton, but this provision applies regardless
of whether or not an endorsement has been issued.
The Workers' Compensation policy shall be endorsed with a waiver of subrogation in favor of
the City of Stockton for all work performed by the Contractor, its employees, agents, and
subcontractors. This provision applies regardless of whether or not an endorsement has been issued.
