Petition by plaintiff Merchants under RSA 491:22 for a declaratory judgment of the rights, duties, and obligations of the parties under an automobile liability policy *361 issued by it covering defendant Transformer’s 1962 Chevrolet truck.
On October 27, 1962, defendant was using this truck, loaded with filters and oil purification equipment, to cleanse the oil in certain transformers located on a pumping plant substation of the Government near Frazer, Montana. At about 6:00 P.M. on that day a truck owned by Westland Oil Company of Montana was filling with propane gas the purification equipment tank of Transformer’s vehicle. There was an explosion and a resulting fire which caused damage to Transformer’s vehicle, to portions of the substation, and to a rented pickup truck. Transformer sued Westland in the United States District Court of Montana and Merchants intervened to recover payments made to Transformer under its collision policy. After several days of trial the action was settled by all the parties with prejudice. The Government under clause A-6 of its contract with Transformer withheld $3,498 in payment of damages suffered as a result of the fire. Thereafter Transformer sued Merchants to recover this amount whereupon Merchants filed this petition for declaratory judgment.
The issues raised by the petition were reserved and transferred in the form of questions by Flynn, J., on an agreed statement of facts.
The first question transferred is whether coverage is excluded by certain clauses in the Merchants policy, especially exclusion (b) pertaining to “liability assumed by the insured under any contract or agreement” and exclusion (f) which applies to property “in charge of the insured.”
Clause A-6 of the contract between Transformer and the Government provided: “Responsibility of contractor. The contractor shall be responsible for the safety of his employees and for any injury or damage done by them and shall protect the Government from any claims resulting therefrom. The contractor shall make good at his own expense all damage to Government property resulting from his operations under this contract, or resulting from the fault or negligence of any of his employees.”
By the terms of its policy Merchants agreed to pay on behalf of its insured Transformer “all sums which the insured shall become legally obligated to pay as damages because
*362
of injury to or destruction of property.” The purpose of exclusion (b) is to limit the insurer’s liability to that which the law imposes on all insureds alike by excluding other risks which the insured might assume by contract or agreement. 1 Long, Law of Liability Insurance

Merchants also contends that it is not liable for this damage to the Government’s substation because it was property in charge of the insured and thus subject to exclusion (f). This court has held the general rule to be that, where the property damaged is merely incidental to the property upon which the work is being performed by the insured, the property damaged is not in the control of the insured within the meaning of such an exclusion clause.

v.
Kamieniecki,
The second question transferred is whether condition 7 of the policy prevents any action by Transformer against Merchants because the Government withheld the cost of repair of the fire damage from payments due Transformer under their contract.
Condition 7 reads in part as follows: “No action shall lie against the company. . . until the amount of the insured’s obligation to pay shall have been finally determined either by judgment against the insured after actual trial or by written agreement of the insured, the claimant and the company.” This clause is intended to protect the insurer from collusive or overly generous or unnecessary settlements by the insured at the expense of the insurer.

v.
Hartford Acc. & Ind. Co.,
The agreed facts state that Transformer sued Westland Oil in Montana; that Merchants intervened in the action; and that, after several days of trial, the parties settled the action with prejudice. The Government was not a party to the action. The record before us contains nothing to indicate that Transformer’s obligation to pay the Government has “been finally determined either by judgment against the insured after actual trial or by written agreement....” It follows that the second question is answered “Yes,” until such time as condition 7 of the policy has been complied with. Dubois v. Pouliot supra.
The third question is whether RSA 491:22-a (supp.) applies to the pending action. This section adopted June 20, 1969, effective August 19, 1969 (Laws 1969, Ch. 255), reads as follows: “In any petition.. . [for declaratory judgment] to determine the coverage of a liability insurance policy, the burden of proof concerning the coverage shall be upon the insurer whether or not he institutes the petition or the claimant asserting the coverage institutes the petition.” Prior thereto the law was well established in this jurisdiction that in such a proceeding the burden of establishing coverage rested on the insured.

v.
Indemnity Co.,
The fire involved took place October 27, 1962. The petition for declaratory judgment was filed January 9, 1969. Both preceded the August 19, 1969, effective date of the section in question. The reserved case with the agreed statement of facts transferring the questions before us was dated July 10, 1971, almost two years after the effective date of this law.
Petitions for declaratory judgments are means created by the legislature for determining rights of parties at an earlier date than would be possible otherwise.
