It is agreed that the amount or amounts of the Reinsurer’s liability hereunder in respect of any losses shall not be increased by reason of the inability of the Company to collect from any other reinsurer whether specific or general, any amount or amounts which may have become due from them whether such inability arises from the insolvency of such other reinsurance or otherwise.

In the event that the Company insured through pools or assigned risk plans risks of the character described in sub-divisions 3, 4 and 5 of paragraph B of Section 4 of Exhibit “B”, additional premium, if any, shall be determined upon submission of underwriting data to the Reinsurers. As soon as practicable after such time as the fact of insurance of an occupation, employment or risk listed in Paragraph B of Section 4 of Exhibit “B” is disclosed to the Company, the Company shall notify the Reinsurers and will provide sufficient underwriting data so as to permit the application of the commensurate reinsurance rate or premium from inception of such hazardous risk.

It is understood that failure on the part of the Company to comply with this requirement due to oversight or error shall not prejudice the reinsurance provided by this Contract. The Company shall, however, as soon as such oversight or error comes to its attention, take prompt steps to contact the Reinsurers and proceed to the correction of the oversight or error as provided in this Contract.

ARTICLE 4 — SUBROGATION

All subrogation recoveries made by either party subsequent to payments made by the Reinsurers under this Contract shall be applied as if made prior to said payments and all necessary adjustments shall be made between the Company and the Reinsurers as soon as practicable after said subrogation recovery is made.

The Company shall have the right, before the happening of the accident or occurrence, to waive its right of subrogation.

As used in this Exhibit the following terms shall have the meanings stated herein:

	A.		“Policies”. Policies, contracts, endorsements or binders, including but not limited to those by which the Company undertakes to offer and pay “voluntary compensation” benefits, those by which the Company undertakes to make payments to augment compensation benefits, those by which the Company affords reinsurance or excess insurance to Workmen’s Compensation or Employers’ Liability risks and those by which the Company undertakes to participate in voluntary or statutory Pools or assigned-risk plans.

	C.		“Accident or Occurrence”. Any one accident or occurrence or, if a series of accidents or occurrences arising out of one event, such series of accidents or occurrences provided, however, that with respect to disease, including death resulting therefrom, the terms “accident or occurrence” and “series of accidents or occurrences” shall mean the claim or series of claims for which the Company may be liable, on account of diseases or deaths resulting therefrom, assigned by the Company to each calendar year of coverage under any one policy or renewals thereof. In making such assignments the Company will be bound by the following principles:

	1.		If liability is placed solely upon the employer or insurer as of the date the claimant’s disability commences or becomes manifest and that date is within a period of coverage under an applicable policy issued by the Company, the claim is to be assigned to the calendar year of such date;
	2.		If assignment is not made on the basis stated in the preceding subparagraph the claim is to be assigned to the calendar year of the date of the claimant’s last injurious exposure during a period of coverage under an applicable policy issued by the Company.
			It is also agreed that disease cases which are not chargeable to this Contract under the above principals and which are not chargeable to a previous reinsurance contract shall be charged to this Contract and be treated as an accident occurring during 1975.

-4-

Notwithstanding anything to the contrary above set forth it is agreed that as to any policyholder to whom the Company issues disease coverage which is in effect for only 12 consecutive months or less all of the Company’s losses on accout of disease claims will be charged for the purpose of this reinsurance to the calendar year which includes the date the Company’s disease coverage became effective.

Notwithstanding the foregoing, where a policyholder requests that it be issued two or more policies in circumstances where applicable manual rules permit the issuance of a single policy, such policies shall be regarded as a single policy for purposes of assigning disease claims to calendar year coverage.

SECTION 6 — NOTICE TO REINSURERS

As soon as practicable after it appears probable that the Company’s ultimate net loss on account of any one accident or occurrence will exceed the amount above which the Reinsurers are liable under this Exhibit the Company shall notify the Reinsurers and provide them full information relative thereto, and copies of all papers that may be desired by them, and the Reinsurers shall be given every opportunity to participate in the defense of any such suit, proceeding or claim at their own expense.

SECTION 7 — PAYMENT BY THE COMPANY

The Company shall be the sole judge as to what claims are covered under its policies, as to the liability of the Company therefor and as to the amounts which the Company should pay thereon, and the Reinsurers shall be bound by the judgement of the Company as to such matters.

All settlements of losses effected by the Company shall be binding upon the Reinsurers, and the Reinsurers shall be liable for their proportion thereof.

SECTION 8 — CLAIMS AGAINST REINSURERS

The Company shall, within 12 months after it has paid any amount of ultimate net loss for which the Reinsurers may be liable under this Exhibit, submit to the Reinsurers a definite claim for such amount. If any subsequent losses shall be paid by the Company on account of the same accident or occurrence, additional claims hereunder shall be similarly made from time to time. Losses shall be due and payable by the Reinsurers within 15 days after claim hereunder is proved.

All salvages, recoveries and payments recovered or received subsequent to a loss settlement under this Exhibit shall be applied as if recovered or received prior to the said settlement and all necessary adjustments shall be made by the parties hereto.

SECTION 9 — COMMUTATION

	A.		At any time subsequent to two years after the date of notice to the Reinsurers of an accident or occurrence which may involve this Exhibit, representatives of the parties shall, at the request of either of them, meet in Boston, Massachusetts, for the purpose of appraising the Reinsurers’ ultimate liability to the Company under this Exhibit on account of the claims resulting from such accident or occurrence. The value of the Company’s incurred losses from such claims shall be calculated as of a date certain not more than 45 days after the date the appraisal begins. In such calculation, the value of each case as of, such date shall be determined with the discount figured at 2 1/2% per annum and by the use of the latest available remarriage, survivorship, and mortality tables to determine probabities of remarriage and normal life expectancies.
	B.		If the parties agree as to the amount of the Reinsurers’ ultimate liability to the Company on account of the claims resulting from such accident or occurrence, the Reinsurers shall, on or before the date as of which the claims were valued, redeem their liability hereunder by the payment of such amount to the Company.
	C.		If the parties cannot, at such first appraisal, reach an agreement as to the amount of the Reinsurers’ ultimate liability to the Company on account of such accident or occurrence, settlement hereunder shall be deferred for one year, when a second appraisal of the amount due the Company from the Reinsurers shall be made in accordance with the provisions of Paragraph A of this Section. If the parties then agree as to the amount of the Reinsurers’ ultimate liability to the Company on account of such accident or occurrence, settlement shall be made as outlined in Paragraph B of this Section.
	D.		If the parties do not reach an agreement as a result of the second appraisal, settlement hereunder shall be deferred for another year, at the end of which a third and last such appraisal of the Reinsurers’ ultimate liability to the Company shall be made. If, as a result of such appraisal, the parties agree on the amount of the Reinsurers’ ultimate liability to the Company, settlement will be made as provided in Paragraph B of this Section. If they do not reach an agreement as a result of such third appraisal, the amount of the Reinsurers’ liability to the Company on account of such accident or occurrence shall promptly be determined by arbitration, in accordance with Article 9 of the Contract.
