Each party to this Agreement shall retain the right of continuing access to the books and records of the other party sufficient to permit the parties to fulfill all of their obligations under this Agreement, subject to the provisions of Section 8 of this Agreement. The parties agree that any appropriate regulatory authority shall have access to books and records associated with this Agreement during normal business hours and upon reasonable advance notice. The books, accounts, and records of each Company and Glidepath shall be so maintained as to clearly and accurately disclose the nature and details of the transactions contemplated in this Agreement.

2. Duty of Care.

(a) All services under this Agreement will be performed with the same standards of care, prudence and diligence which the parties hereto exercise in the performance of their own management, administrative and general corporate responsibilities.

(b) At all times during the providing of Services and thereafter, Glidepath and the Companies will treat all proprietary, confidential or secret information and materials of the other party as if such all proprietary, confidential, and secret information was its own. In addition to protecting confidential information and materials of the other party in accordance with the terms of this Agreement, Glidepath and the Companies agree to implement reasonable measures to establish a written information security program with respect to nonpublic personally identifiable information (“Personal Information”), to the extent such information is shared, which (i) ensures the security and confidentiality of such information, (ii) protects against any anticipated threats or hazards to the confidentiality, security or integrity of Personal Information, and (iii) protects against any unauthorized access to or use of Personal information, including but not limited to, any access or use that could result in substantial harm or inconvenience to the parties or the parties’ customers, employees, or agents. Glidepath and the Companies will restrict access to Personal Information to those individuals that have a legitimate need to access such information.

(c) Glidepath and the Companies will immediately notify the other in the event of any circumstances involving a Breach of Security (defined below) of Personal Information and reasonably cooperate in the investigation of any such incident. Breach of

2

Security is defined herein to mean any actual or suspected unauthorized access to or use of Personal Information. In addition, Glidepath and the Companies agree to provide each other with any additional information, reasonably required by the other party, in sufficient detail to enable the other party to comply with any and all legal and regulatory requirements resulting from such Breach of Security.

3. Fee.

(a) In consideration of the Services provided by Glidepath as described in Section 1 of this Agreement and Appendix A, GALIC, AILIC and MNLIC will collectively pay to Glidepath an amount that reflects the actual costs and expenses which are directly or indirectly related to the Services and may include allocable salaries and benefits and other similar expenses, which will be prorated for any period less than a full year during which this Agreement is in effect (“Fee”). An estimate of the current Fee is attached hereto as Appendix B. The parties will agree upon and determine the Fee on an annual basis.

(b) The parties further agree that: (i) the Fee for the Services will be fair and reasonable; (ii) expenses incurred and payment received will be allocated on an equitable basis in conformity with customary insurance accounting practices consistently applied; and (iii) the books, accounts and records of the parties will be so maintained as to clearly and accurately disclose the nature and details of the Services and the Fee, including such accounting information as is necessary to support the reasonableness of the Fee.

(c) Upon request by GALIC, AILIC or MNLIC, Glidepath will, within thirty (30) days after the expiration of each calendar year during which this Agreement is in effect, furnish the management of GALIC, AILIC or MNLIC with a written statement of amounts received and expended pursuant to this Agreement, in such detail and with such supporting documentation as the management of GALIC, AILIC or MNLIC may reasonably require.

(d) Unless otherwise agreed to by the parties, the Fee will be paid at least on a biweekly basis. The Fee will be paid in United States dollars and may be made by electronic transfer or such other means, as agreed upon by the parties. The Fee will be due and payable no later than thirty days after receipt of the bill. Any undisputed portion of the Fee payments made after the thirtieth (30^th) day following the receipt of the bill will accrue interest on a daily basis at the then Applicable Long Term Federal Rate as regularly published in the Internal Revenue Code of the United States Treasury.

(e) None of the Companies shall advance funds to Glidepath except to pay for the Services provided under this Agreement. All funds and invested assets of each of the Companies are the exclusive property of such Company, held for the benefit of such Company and are subject to the control of such Company.

(e) Unless otherwise agreed between the parties, any indebtedness between Glidepath and the Companies which is not evidenced by a written instrument requiring

3

payment of interest will bear interest at the minimum rate of interest specified in Section 1.482-2(a)(2) of the United States Treasury Regulations, with such interest to accrue six (6) months after the date the debt arises.

4. Expenses To Be Borne By the Companies. GALIC, AILIC and MNLIC will each be solely responsible for their own expenses (i.e. expenses incurred by GALIC, AILIC and MNLIC not related to goods and services associated with the Services provided by Glidepath).

Such persons will receive no compensation from the applicable Company for their services to such Company in such capacities. Any person employed or formerly employed by Glidepath who may be or become an employee of, and paid by, any or all of the Companies will be deemed, when acting within the scope of his or her employment by such Company, to be acting in such employment solely for such Company and not as a Glidepath employee or agent, except when separate consulting agreements are entered into between Glidepath and employees of any or all of the Companies.

8. Limitation of Liability and Indemnification.

(a) In the absence of misfeasance, violation of applicable law, bad faith or negligence in the performance of its duties or from reckless disregard by it of its obligations and duties under this Agreement, neither Glidepath nor the Companies will be liable to the other for any act or failure to act in connection with the performance of its duties hereunder.

This Agreement may be terminated with or without cause at any time by the Companies or by Glidepath on ninety (90) days’ written notice to the other party hereto. This Agreement will automatically terminate in the event of its assignment, unless such assignment has been consented to by the parties in advance. In the event of the termination of this Agreement: (a) all records in Glidepath’s possession pertaining to the operation of the Companies, together with any other Company property in its possession, will promptly be delivered to the applicable Company or its representative authorized to receive the same, it being understood by the Companies that Glidepath may retain copies of any documents or information necessary for Glidepath to fulfill its own legal obligations with respect to the Companies, including those which arise by virtue of any ownership interest which Glidepath may have in the Companies; and (b) Glidepath’s right to compensation will immediately cease, except for (i) any payments, or pro rata portions thereof, which are due on the date of termination; and (ii) Services which must be provided in order to wind up any ongoing matters, including but not limited to matters relating to pending litigation, tax accounting and filing services, Internal Revenue Service audits, and employee benefit administration matters. Glidepath shall have no automatic right to terminate this Agreement with respect to any of the Companies if any action is taken against such Company pursuant to applicable supervision, rehabilitation, and liquidation laws. Glidepath shall continue to maintain systems, programs, or other infrastructure notwithstanding action being taken against any of the Companies pursuant to applicable insurers supervision, rehabilitation, and liquidation laws, and will make them available for so long as Glidepath continues to receive timely payment for services rendered.

10. Entire Agreement; Amendments; No Assignment.

Neither this Agreement nor any rights or obligations hereunder may be assigned or otherwise transferred, in whole or in part, by any party, and any attempted assignment in contravention of this Agreement is null and void.

11. Receivership. In the event any action is taken against any of the Companies under applicable supervision, rehabilitation or liquidation laws, the

12. Miscellaneous; Governing Law. The captions in this Agreement are included for convenience of reference only, and in no way define or limit any of the provisions hereof or otherwise change their construction or effect. This Agreement is hereby deemed to have been made under and governed by the laws of the State of Ohio, without regard to any conflict of law principles.
