ARTICLE IV

DEFERRALS AND DEFERRED COMPENSATION ACCOUNTS

4.1. Compensation Eligible for Deferral. To the extent authorized by the Committee, a Participant may elect to defer compensation or awards which may be in the form of cash, Stock, Stock-denominated awards or other property to be received from an Employer, including salary, annual bonus awards, long-term awards, shares issuable on stock option exercise and compensation payable under other plans and programs, employment agreements or other arrangements, or otherwise, as may be provided under the terms of such plans, programs and arrangements or as designated by the Administrator. The Committee may impose limitations on the amounts permitted to be deferred and other terms and conditions on deferrals under the Deferred Compensation Plan. Any such limitations, and other terms and conditions of deferral, shall be set forth in the rules relating to the Deferred Compensation Plan or election forms, other forms, or instructions published by or at the direction of the Administrator. The Committee may permit awards and other amounts to be treated as deferrals under the Deferred Compensation Plan, including deferrals that may be mandatory as determined by the Committee in its sole discretion or under the terms of another plan or arrangement of an Employer, for administrative convenience or otherwise to serve the purposes of the Deferred Compensation Plan and such other plan or arrangement.

4.2. Irrevocability of Deferral Elections. Once a Deferred Compensation Agreement, properly completed, is received by the Administrator, the elections of the Participant shall be irrevocable; provided, however, that the Administrator may, in its discretion, permit a Participant to elect a further deferral of amounts credited to a Deferred Compensation Account by filing a later election form; provided, further, that, unless otherwise approved by the Administrator, any election to further defer amounts credited to a Deferred Compensation Account must be made at least six months prior to the date such amounts would otherwise be payable.

4.3. Date of Election. An election to defer compensation or awards hereunder must be received by the Administrator prior to the date specified by the Administrator. Under no circumstances may a Participant defer compensation or awards if the Participant has, at the time of deferral, a legally enforceable right to current receipt of such compensation or awards.

-4-

4.4. Establishment of Deferred Compensation Accounts. One or more Deferred Compensation Accounts will be established for each Participant, as determined by the Administrator. The amount of compensation or awards deferred with respect to each Deferred Compensation Account will be credited to such Account as of the date on which such amounts would have been paid to the Participant but for the Participant’s election to defer receipt hereunder, unless otherwise determined by the Administrator. With respect to any fractional shares of Stock or Stock-denominated awards, the Administrator, in its sole discretion, shall pay such fractional shares to the Participant in cash, credit the Deferred Compensation Account with cash in lieu of depositing fractional shares into the Deferred Compensation Account, or credit the Deferred Compensation Account with a fraction of a share calculated to at least three decimal places. Unless otherwise determined by the Administrator, amounts credited to a Deferred Compensation Account shall be deemed invested in a hypothetical investment as of the date of deferral. The amounts of hypothetical income and appreciation and depreciation in the value of such Account will be credited and debited to, or otherwise reflected in, such Account from time to time.

4.5. Hypothetical Investment Vehicles. Subject to the provisions of Sections 4.6 and 4.8, amounts credited to a Deferred Compensation Account shall be deemed to be invested, at the Participant’s direction, in one or more investment vehicles as may be specified from time to time by the Administrator. The Administrator may change or discontinue any hypothetical investment vehicle available under the Deferred Compensation Plan in its discretion; provided, however, that each affected Participant shall be given the opportunity, without limiting or otherwise impairing any other right of such Participant regarding changes in investment directions, to redirect the allocation of his Deferred Compensation Account deemed invested in the discontinued investment vehicle among the other hypothetical investment vehicles, including any replacement vehicle.

4.6. Allocation and Reallocation of Hypothetical Investments. A Participant may allocate amounts credited to his Deferred Compensation Account to one or more of the hypothetical investment vehicles authorized under the Deferred Compensation Plan. Subject to the rules established by the Administrator, a Participant may reallocate amounts credited to his Deferred Compensation Account to one or more of such hypothetical investment vehicles as of the next day following the filing of the Participant’s election to reallocate amounts credited to his Deferred Compensation Account. The Administrator may, in its discretion, restrict allocation into or reallocation by specified Participants into or out of specified investment vehicles or specify minimum or maximum amounts that may be allocated or reallocated by Participants.

4.7. Dividend Equivalents. Dividend equivalents will be credited on Stock Equivalent Units credited to a Participant’s Deferred Compensation Account as follows:

(a) Cash and Non-Stock Dividends. If American Water Works declares and pays a dividend on Stock in the form of cash or property other than shares of Stock, then a number of additional Stock Equivalent Units shall be credited to a Participant’s Deferred Compensation Account as of the payment date for such dividend equal to (i) the number of Stock Equivalent Units credited to the Deferred Compensation Account as of the record date for such dividend, multiplied by (ii) the amount of cash plus the fair market value of any property other than shares actually paid as a dividend on each share at such payment date, divided by (iii) the closing market price of a share of Stock at such payment date as published in The Wall Street Journal report of New York Stock Exchange Composite Transactions.

(b) Stock Dividends and Splits. If American Water Works declares and pays a dividend on Stock in the form of additional shares of Stock, or there occurs a forward split of Stock, then a number of additional Stock Equivalent Units shall be credited to the Participant’s Deferred Compensation Account as of the payment date for such dividend or forward Stock split equal to (i) the number of Stock Equivalent Units credited to the Deferred Compensation Account as of the record date for such dividend or split, multiplied by (ii) the number of additional shares actually paid as a dividend or issued in such split in respect of each share of Stock.

4.8. Restrictions on Participant Direction. The provisions of Sections 4.5 and 4.6 notwithstanding, the Administrator may restrict or prohibit reallocations of amounts deemed invested in specified investment vehicles, and subject such amounts to a risk of forfeiture and other restrictions, in order to conform to restrictions applicable to Stock, a Stock-denominated award, or any other award or amount deferred under the Deferred Compensation Plan and resulting in such deemed investment, to comply with any applicable law or regulation, or for such other purpose as the Administrator may determine is not inconsistent with the Deferred Compensation Plan. Notwithstanding any other provision of the Deferred Compensation Plan to the contrary, deferrals of all Stock-denominated awards under the American Water Works Company, Inc. Long-Term Performance-Based Incentive Plan shall be credited to the Participant’s Deferred Compensation Account in the form of Stock Equivalent Units and may not be reallocated or deemed reinvested in any other investment vehicle.

ARTICLE V

DISTRIBUTIONS

5.1. Election of Distribution Date. At the time a Participant makes an election to defer compensation under Article IV, such Participant shall also specify in writing in the Deferred Compensation Agreement the date or event on which the payment of the Participant’s Deferred Compensation Account shall be made. Payments in settlement of a Deferred Compensation Account shall be made as soon as practicable after the date or dates (including upon the occurrence of specified events), and in such number of installments, as may be directed by the Participant in his election relating to such Deferred Compensation Account, provided that, in the event of termination of employment for reasons other than Retirement or Disability, a single lump sum payment in settlement of any Deferred Compensation Account (including an Account with respect to which one or more installment payments have previously been made) shall be made as promptly as practicable thereafter, unless otherwise determined by the Administrator.

5.2. Distribution of Mandatory Deferrals Not Elected To Be Extended. If the Participant has not made an election to extend the deferral period of any mandatory deferral of a portion of his annual incentive award to be earned under the Annual Incentive Plan for any Plan Year, a payment of the cash value of the Stock Equivalent Units credited to his Deferred Compensation Account attributable to such mandatory deferral, including additional units credited as a result of dividends as provided under Section 4.7, shall be made on the date the period of mandatory deferral ends.

5.3. Method of Payment. All distributions under this Deferred Compensation Plan shall be in the form of a cash payment; provided, however, that all deferrals of Stock-denominated awards under the American Water Works Company, Inc. Long-Term Performance-Based Incentive Plan shall be paid by delivery of shares of Stock reserved under such Plan.

5.4. Special Election for Early Distribution. A Participant may apply to the Administrator for early distribution of all or any part of his Deferred Compensation Account excluding any amounts attributable to mandatory deferrals that have not been credited to his Deferred Compensation Account for the minimum period of mandatory deferral. Such early distribution shall be made in a single lump sum, provided that 10% of the amount withdrawn in such early distribution shall be forfeited to the Participant’s Employer prior to payment of the remainder to the Participant. In the event a Participant’s early distribution election is submitted within one year after a Change in Control, the forfeiture penalty shall be reduced to 5%.

-7-

5.5. Distributions on Death. In the event of a Participant’s death before his Deferred Compensation Account has been distributed, distribution of his entire account (including mandatory deferrals) shall be made to the Beneficiary selected by the Participant in a single lump sum payment within 30 days after the date of death (or, if later, after the proper Beneficiary has been identified). A Participant may from time to time change his designated Beneficiary without the consent of such Beneficiary by filing a new designation in writing with the Administrator. If no Beneficiary designation is in effect at the time of the Participant’s death, or if the designated Beneficiary is missing or has predeceased the Participant, distribution shall be made to the Participant’s estate.

5.6. Valuation of Cash Distributions. All cash distributions under this Deferred Compensation Plan shall be based upon the cash value of the investment credited to a Participant’s Deferred Compensation Account as of the date immediately preceding the date of the distribution. It is understood that administrative requirements may lead to a delay between such valuation date and the date of distribution, not to exceed 30 days.

5.7. Financial Emergency and Other Payments. Other provisions of this Deferred Compensation Plan notwithstanding, if, upon the written application of a Participant, the Administrator determines that the Participant has a financial emergency of such a substantial nature and beyond the individual’s control that payment of amounts previously deferred under this Deferred Compensation Plan is warranted, the Administrator may direct the payment to the Participant of all or a portion of the balance of his Deferred Compensation Account and the time and manner of such payment.

ARTICLE VI

FUNDING AND PARTICIPANT’S INTEREST

6.1. Deferred Compensation Plan Unfunded. This Deferred Compensation Plan shall be unfunded and no trust shall be created by this Deferred Compensation Plan. The crediting to each Participant’s Deferred Compensation Account shall be made through record keeping entries. No actual funds shall be set aside; provided, however, that nothing herein shall prevent the Employers from establishing one or more grantor trusts from which benefits due under this Deferred

-8-

Compensation Plan may be paid in certain instances. All distributions shall be paid by the Employer from its general assets and a Participant (or his Beneficiary) shall have the rights of a general, unsecured creditor against the Employer for any distributions due hereunder. This Deferred Compensation Plan constitutes a mere promise by the Employers to make benefit payments in the future.

6.2. Participant’s Interest in Plan. A Participant has an interest in the cash value of amounts credited to his Deferred Compensation Account. A Participant has no rights or interests in Stock or dividends and has no right to elect delivery of shares of Stock except as provided in Section 5.3.

ADMINISTRATION AND INTERPRETATION

7.1. Administration. Except where certain duties are delegated to the Administrator, the Committee shall be in charge of the operation and administration of this Deferred Compensation Plan.

administrators, successors and assigns. The Committee’s or Administrator’s determinations hereunder need not be uniform, and may be made selectively among Eligible Employees, whether or not they are similarly situated. Any actions to be taken by the Committee or Administrator will require majority vote of the Committee or the Administrator. If a member of the Committee or the Administrator is a Participant in this Deferred Compensation Plan, such member may not decide or determine any matter or question concerning his benefits under this Deferred Compensation Plan that such member would not have the right to decide or determine if he were not a member.

(a) The Participant or the Participant’s Claimant shall repay to his Employer any such expenses theretofore paid or advanced by his Employer if and to the extent that the party disputing the Participant’s rights obtains a judgment in its favor from a court of competent jurisdiction from which no appeal may be taken, whether because the time to do so has expired or otherwise, and it is determined by the court that such expenses were not incurred by the Participant or the Participant’s Claimant while acting in good faith; provided, further, that

7.5. Indemnification for Liability. The Employers shall indemnify the Administrator, the members of the Committee, and the employees of any Employer to whom the Administrator delegates duties under this Deferred Compensation Plan, against any and all claims, losses, damages, expenses and liabilities arising from their responsibilities in connection with this Deferred Compensation Plan, unless the same is determined to be due to gross negligence or willful misconduct.

AMENDMENT AND TERMINATION

8.1. Amendment and Termination. The Committee shall have the right, at any time, to amend or terminate this Deferred Compensation Plan, in whole or in part, provided that such amendment or termination shall not adversely affect the right of any Participant or Beneficiary to payment of Participant’s Deferred Compensation Account.
