RECITALS

WHEREAS, Patrons Connecticut has extensive experience in the operation of its insurance business and has trained personnel, equipment and facilities for conducting its present and future insurance operations (which term as hereinafter used shall include reinsurance and investment operations and activities incidental, ancillary or complementary to an insurance business); and in time it is expected that Patrons Rhode Island may develop such experience, personnel, equipment and facilities; and

WHEREAS, Patrons Connecticut and Patrons Rhode Island desire to arrange that such party having the appropriate experience, personnel, equipment and facilities shall provide services and facilities upon request, to the party in need of such services and facilities, and desire to provide generally for such events; and

WHEREAS, the parties desire to provide for the performance of certain administrative and other services (hereinafter called “services”) for their insurance operations and desire further to arrange to make use in their day-to-day operations of certain property, equipment and facilities (hereinafter called “facilities”) of the parties as each may from time to time request, and the parties contemplate that this arrangement will result in certain operating economies and will improve services to the mutual benefit of them; and

WHEREAS, the parties desire to assure that all charges for services and the use of facilities incurred hereunder are reasonable and are arrived at in a fair and equitable manner; and

WHEREAS, the parties desire to identify generally the services to be rendered and the facilities to be used; and

WHEREAS, to the extent a party provides services or facilities to the other pursuant to the terms of this Agreement it may be denominated a “provider” and to the extent that it receives services or the use of facilities of the other it may be denominated a “recipient”.

Now, therefore, in consideration of the premises and of the promises set forth herein, the parties agree as follows:

1. PERFORMANCE OF SERVICES AND JOINT USE OF FACILITIES.

(a) Services. Each party agrees, to the extent requested by the other, to perform services of a type similar to that which provider customarily performs in the course of its own insurance operations for the recipient as such recipient may determine to be reasonably necessary in the conduct of its insurance operations. The services which a provider shall perform in whole or in part for the recipient may include, but need not be limited to: accounting, tax and auditing services; legal services; actuarial services; employee benefit plans and personnel administration; sales services; software development services; electronic data processing operations; communications operations and investment services.

(b) Facilities. Each party agrees to the extent requested by a recipient to make available its facilities to the recipient as the recipient may determine to be reasonably necessary in the conduct of its insurance operations. The facilities of a provider which the recipient may use in whole or in part shall include, but need not be limited to: electronic data processing equipment; business property, whether owned or leased; communications equipment; and a security vault.

(c) Best Efforts. Each party agrees at all times to use its best efforts to maintain sufficient personnel and facilities of the kind necessary to perform this Agreement, in accordance with the reasonable requests of a recipient and upon reasonable notice to the provider. If, however, a provider determines that for any reason, including its own needs, it is or will be unable to perform any service or provide any facility under this Agreement, it shall immediately notify the recipient so that the recipient can make other arrangements for such service or facility.

(d) Designation of Capacity of Personnel. Even though a provider utilizes its personnel to perform services for a recipient pursuant to this Agreement, such personnel shall at all times remain employees of the provider. The provider shall alone retain full liability to such personnel for their welfare, salaries, fringe benefits, legally required employee contributions and tax obligations.

(e) Status of Facilities. No facility of a provider used in performing services for or subject to use by a recipient shall be deemed to be transferred, assigned, conveyed or leased by performance or use pursuant to this Agreement, except as the provider and recipient may otherwise agree in writing. The amount charged as rent for any facilities leased pursuant to any such writing shall be computed in accordance with the provisions of Section 2 of this Agreement.

2

(f) Exercise of Judgment in Rendering Services. In providing any service hereunder which requires the exercise of judgment by the provider, the provider will endeavor to perform such service in accordance with any reasonable and appropriate standards and guidelines the recipient develops and communicates to the provider.

(g) Control. The performance or receipt of services or the making available or use of facilities pursuant to this Agreement shall in no way impair the absolute control of the business and operations of each of the parties by its own Board of Directors.

2. CHARGES. Recipient agrees to pay to the provider a charge equal to all expenses, direct and indirect, reasonably and equitably determined by the provider to be attributable to the recipient for services and facilities provided by the former to the latter pursuant hereto, except to the extent application of laws or regulations would otherwise require.

The bases for determining such charges to the recipient shall be similar to those used by the provider for internal cost distribution including, where applicable, time records prepared for this purpose. Such bases shall be modified and adjusted where necessary or appropriate to reflect fairly and equitably the actual incidence of cost incurred by the provider on behalf of the recipient.

The provider’s determination of charges hereunder shall be conclusive as between such parties, except that if the recipient objects to any such determination, it shall so advise the provider within thirty (30) days of receipt of notice of said determination. Unless such parties can reconcile any such objection, or otherwise agree, they shall select a firm of independent certified public accountants which shall determine the charges properly allocable to the recipient and shall, within a reasonable time, submit such determination, together with the basis therefor, in writing to both parties whereupon such determination shall be binding. The expenses of any such determination by a firm of independent certified public accountants shall be borne as determined to be equitable by such accountants.

3. PAYMENT. The provider shall submit to the recipient within thirty (30) days of the end of each calendar month (or such other interval not greater than quarterly as such parties may agree), a written statement of the amount estimated to be owed by the recipient to the provider for services and the use of facilities pursuant to this Agreement in that calendar month (or interval) and the recipient shall pay to the provider within thirty (30) days following receipt of such written statement the amount set forth in the statement.

3

4. ACCOUNTING RECORDS AND DOCUMENTS. The provider shall be responsible for maintaining full and accurate accounting records of all services rendered and facilities used pursuant to this Agreement and such additional information as the recipient may reasonably request for purposes of its internal bookkeeping and accounting operations. The provider shall keep such accounting records insofar as they pertain to the computation of charges hereunder available at its principal offices for audit, inspection and copying by the recipient or any governmental agency having jurisdiction during all reasonable business hours.

5. OTHER RECORDS AND DOCUMENTS. Each party shall maintain appropriate records identifying the nature and type of each service requested and provided pursuant to this Agreement, and the person requesting any substantial or ongoing service. All books, records, and files established and maintained by the provider by reason of its performance under this Agreement which, absent this Agreement, would have been held by the recipient shall be deemed the property of such recipient, and, together with records called for pursuant to the first sentence of this paragraph, shall be subject to examination by it and persons authorized by it at all times, and shall be delivered to it on demand.

6. LIABILITY; USE OF SERVICES OR FACILITIES. As services are being performed and facilities made available by a provider, such provider shall have no liability for any action taken or omitted by it in furnishing services and facilities under this Agreement, in good faith and without gross negligence.

7. TERMINATION. This Agreement shall terminate upon the termination of that certain Agreement of Association dated March 25, 1989 between the parties hereto, as amended from time to time, or upon order issued by the Director of the Department of Business Regulation.

8. SETTLEMENT ON TERMINATION. No later than ninety (90) days after the effective date of termination, each party which has provided services shall deliver to the other a detailed written statement for all charges incurred and not included in any previous statement to the effective date of termination. The amounts owed hereunder shall be due and payable within thirty (30) days of receipt of such statement.

9. ASSIGNMENT AND ADDITIONAL PARTIES. This Agreement and any rights pursuant hereto shall not be assignable by any party hereto, except by operation of law. Except as and to the extent specifically provided in this Agreement, nothing in this

4

Agreement, expressed or implied, is intended to confer on any person other than the parties hereto, or their respective legal successors, any rights, remedies, obligations or liabilities, or to relieve any person other than the parties hereto, or their respective legal successors, from any obligations or liabilities that would otherwise be applicable.

10. GOVERNING LAW. This Agreement is made pursuant to and shall be governed by, interpreted under, and the rights of the parties determined in accordance with, the laws of the State of Rhode Island.

11. NOTICE. All notices, statements or requests provided for hereunder shall be deemed to have been duly given by one party to another when delivered by hand to an officer of the other party, or when deposited with the U.S. Postal Service, as certified or registered mail, postage prepaid, addressed to a party at its principal executive offices as such address appears on its most recent annual statement, attention: Chief Executive Officer, or to such other person or place as that party may from time to time designate by written notice sent as aforesaid.

12. ENTIRE AGREEMENT. This Agreement, together with such Amendments as may from time to time be executed in writing by the parties, constitutes the entire Agreement between the parties with respect to the subject matter hereof.
