Purpose. The Company maintains the Retirement Plan, a defined benefit pension plan which is intended to meet the applicable requirements of the Code. The Code places limitations and restrictions on the amount of benefits which may be paid from, and the amount of compensation which may be taken into account in calculating benefits under, the Retirement Plan. The purpose of this Plan is to provide benefits to Participants in the Plan which would otherwise be earned under but may not be provided from the Retirement Plan because of these limitations and restrictions of the Code. It is intended that this Plan only cover a select group of management or highly compensated employees for purposes of ERISA. The Plan is intended to conform to the requirements of Code Section 409A with respect to Post-409A Benefits.

Administration. The Plan will be administered by the Committee. The Committee has the discretionary authority to issue such rules as it deems appropriate and to construe and interpret the provisions of the Plan and make factual determinations thereunder, including the power to determine the rights or eligibility of employees or Participants and any other persons, and the amounts of their benefits under the Plan, and to remedy ambiguities, inconsistencies or omissions. Any decision by the Committee hereunder or with respect hereto shall be final, binding and conclusive on all Participants and all other persons whomsoever. The Committee shall interpret the Plan in a manner that it determines does not result in taxation of Participants under Code Section 409A.

Plan Benefits for Participants Whose Benefits Commenced Prior to December 31, 2008. Pre-409A Benefits that commenced prior to December 31, 2008 will, except as otherwise specifically provided herein, be governed in all respects by the terms of the Plan as in effect as of the date the Participant's benefits commenced and in good faith compliance with Code Section 409A. The benefits provided hereunder with respect to Participants whose benefits commence on or after December 31, 2008 will be governed in all respects by the terms of this Plan, which have been amended to conform the requirements of Code Section 409A for Post-409A Benefits.

Eligibility. Each employee of an Employer who is a participant in the Retirement Plan, who is entitled to receive final average pay or cash balance benefits from the Retirement Plan, and whose benefits thereunder have been limited by the Code as described in Section 2.2 will become a Participant in this Plan. In the event of the death of such a Participant, his Beneficiary shall be entitled to receive the Participant's benefits under the Plan. Benefits payable under the Plan to a Participant or his Beneficiary are determined in accordance with Sections 3.2 and 3.3. Benefits under the Plan with respect to a Participant or Beneficiary (in the event of a Participant’s death) may be comprised of both Pre-409A Benefits and Post-409A Benefits. An Agent entitled to a benefit under the Agents Pension Plan is not eligible for benefits under this Plan with respect to such Agent’s period of employment used to determine his benefit under the Agents Pension Plan. An Agent may be eligible for benefits under this Plan if, after December 31, 2013, he becomes a Participant pursuant to the first sentence of this Section 3.1 but only with respect to his benefits paid from the Retirement Plan.

Amount of Pre-409A Benefits. The amount of any benefits which otherwise would have been provided for a Participant under the Retirement Plan as of December 31, 2004, but which may not be paid from such plan because of the limitations and restrictions imposed by the Code, shall be calculated as provided in this Section 3.2 and paid under this Plan as provided in Section 4 below. Such benefits shall be equal to the excess of: (a) the amount of retirement benefit as of December 31, 2004 which otherwise would have been provided for the Participant (or in the event of his death, his Beneficiary) by the Retirement Plan, determined without regard to the limitations of the Code and by taking

Amount of Post-409A Benefits. The amount of any benefits which otherwise would have been provided for a Participant under the Retirement Plan after December 31, 2004, but which may not be paid from such plan because of the limitations and restrictions imposed by the Code, shall be calculated as provided in this Section 3.3 and paid under this Plan as provided in Section 4 below. Such benefits shall be equal to the excess of: (a) the amount of retirement benefit earned after December 31, 2004 which otherwise would have been provided for the Participant (or in the event of his death, his Beneficiary) by the Retirement Plan, determined without regard to the limitations of the Code and by taking into account any compensation deferred after December 31, 2004 under The Allstate Corporation Deferred Compensation Plan and The Allstate Corporation Deferred Compensation Plan for Employee Agents which is not included as Annual Compensation (as defined in the Retirement Plan) under the Retirement Plan; over (b) the actual amount of retirement benefit determined for the Participant or his Beneficiary under the Retirement Plan after December 31, 2004. Notwithstanding the preceding sentences, if a Participant is entitled to a benefit under the Agents Pension Plan, the amount of retirement benefit earned under paragraph (a) of the preceding sentence or determined under paragraph (b) of the preceding sentence for such Participant shall not take into account such Participant’s period of employment used to determine his benefit under the Agents Pension Plan.

Form and Time of Payment for Pre-409A Benefits and Post-409A Benefits. All Pre‑409A Benefits shall be paid in a single lump sum on the Plan Payment Date for Pre‑409A Benefits, except (i) upon demonstrating a Hardship to the Committee, Pre‑409A Benefits may be paid after the Participant’s Payment Start Date and before the January 1 first following the day preceding the Participant’s Plan Payment Date for Pre‑409A Benefits; or (ii) if a Participant or Beneficiary should die prior to receipt of Pre‑409A Benefits, such benefits shall be paid in a lump sum as soon as practicable thereafter to the estate of such Participant or Beneficiary. Notwithstanding the foregoing, Participants receiving Required Distributions from the Retirement Plan will receive their Pre-409A Benefits at the same time their Retirement Plan Benefits commence. All Post-409A Benefits shall be paid in a single lump sum on the Plan Payment Date for Post-409A Benefits.

Facility of Payment. Any amount payable under the Plan to a person under legal disability or who, in the judgment of the Committee, is unable to properly manage his financial affairs, may be paid to such person's legal representative, or may be applied for the benefit of such person in any manner selected by the Committee.

Review of Benefit Determinations. The Committee will provide notice in writing to any Participant or Beneficiary whose claim for benefits under the Plan is denied and the Committee shall afford such Participant or Beneficiary a full and fair review of its decision if so requested.

Payment and Funding of Benefits. Amounts payable under the Plan to or on account of a Participant shall be paid directly by the Employers, and shall be provided from the general assets of the Employers. No assets of the Employers shall be set aside solely for the purpose of providing benefits hereunder, and the Employers' obligation to pay such benefits is not limited to any particular assets of the Employer. Benefits under the Plan are not funded, the Employers' obligation to pay such benefits is merely a contractual obligation, and a Participant or Beneficiary shall be treated as a general creditor of the Employers with respect to any benefits payable under the Plan.

Payment of Small Benefits. Notwithstanding anything contained herein to the contrary if on December 31, 2018 or any December 31 thereafter (a “Valuation Date”), (i) a Participant has been separated from service for a period of at least six-months prior to such Valuation Date and (ii) the aggregate value of such Participant’s Pre-409A Benefits and Post-409A Benefits, together with the value of any other benefits payable to the Participant under plans that are aggregated with this Plan for purposes of Code Section 409A, on such Valuation Date is less than the applicable dollar amount under Code section 402(g)(1)(B), the Participant’s Pre-409A Benefits and Post-409A Benefits will be paid out on the Plan Payment Date for Small Benefits.

Action by Company. Any action required or permitted to be taken by the Company under the Plan shall be by resolution of its Board of Directors, by resolution of a duly authorized committee of its Board of Directors, or by a person or persons authorized by resolution of its Board of Directors or such committee.

Gender and Number. Where the context admits, words in the masculine gender shall include the feminine and neuter genders, the singular shall include the plural, and plural shall include the singular.

Controlling Law. Except to the extent superseded by laws of the United States, the laws of Illinois shall be controlling in all matters relating to the Plan.

Employment Rights. The Plan does not constitute a contract of employment, and participation in the Plan will not give any employee the right to be retained in the employ of an Employer, nor any right or claim to any benefit under the Plan, unless such right or claim has specifically accrued under the terms of the Plan.

Interests Not Transferable. The interests of persons entitled to benefits under the Plan are not subject to their debts or other obligations and, except as may be required by the tax withholding provisions of the Code or any state's income tax act, may not be voluntarily or involuntarily sold, transferred, alienated, assigned or encumbered.

Successors. The Plan is binding on all persons entitled to benefits hereunder and their respective heirs and legal representatives, and on the Employers and their successors and assigns.

Statute of Limitations. No legal or equitable action involving the Plan may be commenced later than two years from the time the person bringing the action knew, or had reason to know, of the circumstances giving rise to the action. This provision shall not be interpreted to extend any otherwise applicable statute of limitations, nor to bar the Plan from recovering overpayments of benefits or other amounts incorrectly paid to any

Forum for Legal Actions. Any legal or equitable action involving the Plan that is brought by any Participant, any beneficiary or any other person shall be litigated in the federal courts located in the Northern District of Illinois and no other federal or state court.

Legal Fees. Any award of legal fees against the Plan, the Administrative Committee or any member thereof, the Pension Committee or any member thereof, the Board of Directors or any member thereof, any Employer, any of their respective affiliates, officers, directors, employees, or agents (collectively, the “Plan Parties”) in connection with an action involving the Plan shall be calculated pursuant to a method that results in the lowest amount of fees being paid, which amount shall be no more than the amount that is reasonable. In no event shall legal fees be awarded against Plan Parties for work related to (a) administrative proceedings under the Plan or (b) unsuccessful claims brought by a Participant, beneficiary or any other person. In calculating any award of legal fees, there shall be no enhancement for the risk of contingency, nonpayment or any other risk nor shall there be applied a contingency multiplier or any other multiplier. In any action brought by a Participant, beneficiary or any other person against Plan Parties, legal fees of the Plan Parties in connection with such action shall be paid by the Participant, beneficiary or other person bringing the action, unless the court specifically finds that (a) there was a reasonable basis for the action and (b) the action was brought in good faith.

Severability. If a provision of the Plan, including any provision of an amendment to the Plan, shall be held illegal or invalid, the illegality or invalidity shall not affect the remaining parts of the Plan and the Plan shall be construed and enforced as if the illegal or invalid provision had not been included in the Plan.

Normal Form of Payment for Pre-409A Benefits. Except as provided in subsection 4.2, for Participants with a plan payment date on or before January 1, 1996 or Participants who retired under the Company's 1994 Special Retirement Opportunity, benefits under the Plan shall be paid to a Participant (or in the case of his death, to his Beneficiary) monthly, commencing as of the earliest of (i) the Participant's Payment Start Date or (ii) the date 60 days following Participant's Date of Death (or the date the Committee receives notification of the Participant's death, if more than 7 days after Participant's Date of Death) and continuing during his lifetime (or the lifetime of his Beneficiary), with the last payment to be made for the month in which the Participant's or Beneficiary's death occurs. For purposes of this Appendix A, “plan payment date” means the day following the date on which the Retirement Plan becomes obligated to pay a Participant’s benefits.

Optional Forms of Payment for Pre-409A Benefits. In lieu of the form and amount of benefit specified in subsection A.1, a Participant with a plan payment date on or before January 1, 1996 or who retired under the Company's 1994 Special Retirement Opportunity (or in the case of his death, his Beneficiary) may elect (in accordance with subsection A.4) a benefit in such other form as then would be available to such Participant or Beneficiary under the Retirement Plan. The actuarial rates, factors and assumptions used to determine the amount of optional forms of benefit under the Retirement Plan shall be used to calculate the amount of optional forms of payment under this Plan.

Time of Payment for Pre-409A Benefits. For Participants with a Plan Payment Date on or before January 1, 1996 or Participants who retired under the Company's 1994 Special Retirement Opportunity, benefits under the Plan shall be paid as of the earliest of (i) the Participant's Payment Start Date or (ii) the date 60 days following Participant's Date of Death (or the date the Committee receives notification of the Participant's death, if more than 7 days after Participant's Date of Death). Notwithstanding the foregoing, a Participant with a Plan Payment Date on or before January 1, 1996 or who retired under the Company's 1994 Special Retirement Opportunity (or in the case of his death, his Beneficiary) may elect (in accordance with subsection A.4) to defer payment of any lump sum benefits (elected under subsection A.2, if available) to the first or second January 1 next following his Plan Payment Date. If a Participant or Beneficiary elects to defer payment of benefits under this subsection A.3, simple interest (at the post-1990 PBGC rate used to calculate the participant's lump sum, or such other rate as may be used by the Retirement Plan) shall be added to such benefits, to the date of payment. If a Participant or Beneficiary who elects to defer payment of benefits under this subsection 4.3 should die prior to receipt of payment, such benefits shall be paid in a lump sum as soon as practicable thereafter to the estate of such Participant or Beneficiary.

Pre-409A Benefit Payment Elections. For Participants with a plan payment date on or before January 1, 1996 or Participants who retired under the Company's 1994 Special Retirement Opportunity, except as otherwise provided below, elections of an optional form of payment under subsection 4.2 and elections to defer payment under subsection 4.4 shall be irrevocable, must be in writing, and must be filed with the Committee at least 30 days prior to the Participant's plan payment date or, in the case of an election by a Beneficiary, at any time prior to the date 60 days following Participant's Date of Death (or the date the Committee receives notification of the Participant's death, if more than 7 days after Participant's Date of Death). Notwithstanding the foregoing, (i) if a Participant is retiring by mutual agreement with the Company in less than 30 days, and the date of the Participant's retirement is outside his control, the Participant's election may be made at any time prior to his plan payment date; and (ii) elections by a Participant who retires after December 31, 1994 under the Company's 1994 Special Retirement Opportunity must be filed with the Committee on or before the December 31 of the year prior to their plan payment date for Pre-409A Benefits.

Each election under this subsection A.5 shall be irrevocable, must be in writing, and must be filed with the Committee on or before December 31, 1994. The actuarial rates, factors and assumptions used to determine lump sum payments under the Retirement Plan as of December 30, 1994 shall be used to calculate lump sum payments under this subsection A.5.
