Any person or organization or the legal representative thereof who has secured such judgment or written agreement shall thereafter be entitled to recover under this policy to the extent of the insurance afforded by this policy. No person or organization shall have any right under this policy to join Aetna Casualty as a party to any action against the INSURED to determine the INSURED'S liability, nor shall Aetna Casualty be impleaded by the INSURED or his legal representative.

SUBROGATION In the event of any payment under this policy, Aetna Casualty shall participate with the INSURED and the underlying insurers in the exercise of all the INSURED'S rights of recovery against any person or organization liable therefor. The INSURED shall do nothing after loss to prejudice such rights. Recoveries shall be applied first to reimburse any interest (including the INSURED) that may have paid any amount, with respect to liability in excess of the limit of Aetna Casualty's liability, hereunder; then to reimburse Aetna Casualty and any other insurer with which it may be participating on a quota-share basis, up to the amount paid hereunder; and lastly to reimburse those interests (including the INSURED), as to which this insurance is excess, who are entitled to claim the residue, if any; but a different apportionment may be made to effect settlement of a claim by agreement executed by all interests. Reasonable expenses incurred in the exercise of rights of recovery shall be apportioned among all interests in the ratio of their respective losses for which recovery is sought.

CHANGES Notice to any agent or knowledge possessed by any agent or by any other person shall not effect a waiver or a change in any part of this policy or estop Aetna Casualty from asserting any rights under the terms of this policy; nor shall the terms of this policy be waived or changed, except by endorsement issued to form a part of this policy, signed by the President, a Vice President, Assistant Vice President, Secretary or Assistant Secretary of Aetna Casualty.

ASSIGNMENT Assignment of interest under this policy shall not bind Aetna Casualty until its consent is endorsed hereon.

CANCELLATION This policy may be cancelled by the INSURED named in Section 1. by mailing to Aetna Casualty written notice stating when thereafter the cancellation shall be effective. This policy may be cancelled by Aetna Casualty by mailing to the INSURED first named in Section 1. at the address shown in this policy written notice stating when not less than ten days thereafter such cancellation shall be effective. The mailing of notice as aforesaid shall be sufficient proof of notice.

If such INSURED cancels, earned premium shall be computed short rate; if Aetna Casualty cancels, earned premium shall be computed pro rata; but payment or tender of unearned premium is not a condition of cancellation.

IN WITNESS WHEREOF, THE AETNA CASUALTY AND SURETY COMPANY has caused this policy to be signed by its President and a Secretary at Hartford, Connecticut, and countersigned on the Declarations page by a duly authorized agent of the Company.
