(1) The term "underinsured motor vehicles" with reference to coverage offered under any insurance policy regulated under this chapter shall, subject to the terms and conditions of such coverage, be deemed to include an insured motor vehicle where the liability insurer thereof is unable to make payment with respect to the legal liability of its insured within the limits specified therein because of insolvency.
(2) An insurer's insolvency protection shall be applicable only to accidents occurring during a policy period in which its insured's underinsured motorist coverage is in effect where the liability insurer of the tort-feasor becomes insolvent within three years after such an accident. Nothing herein contained shall be construed to prevent any insurer from affording insolvency protection under terms and conditions more favorable to its insureds than is provided hereunder.
(3) In the event of payment to an insured under the coverage required by this chapter and subject to the terms and conditions of such coverage, the insurer making such payment shall, to the extent thereof, be entitled to the proceeds of any settlement or judgment resulting from the exercise of any rights of recovery of such insured against any person or organization legally responsible for the bodily injury, death, or property damage for which such payment is made, including the proceeds recoverable from the assets of the insolvent insurer. Whenever an insurer shall make payment under the coverage required by this section and which payment is occasioned by an insolvency, such insurer's right of recovery or reimbursement shall not include any rights against the insured of said insolvent insurer for any amounts which would have been paid by the insolvent insurer. Such paying insurer shall have the right to proceed directly against the insolvent insurer or its receiver, and in pursuance of such right such paying insurer shall possess any rights which the insured of the insolvent company might otherwise have had, if the insured of the insolvent insurer had personally made the payment.
