An Election of Deferral must be filed with the Secretary, or its agent, at the time designated by the Administrator which will not be later than the end of the month preceding the beginning of the Plan Year to which it will first pertain. Such an Election of Deferral shall be effective on the first day of the Plan Year following the filing thereof or at such other time during such Plan Year as the Administrator may determine appropriate in order to provide for the complete implementation of such election, and may relate solely to Compensation for services not yet performed as of the date of the election.

Each Election of Deferral filed subsequent to the initial Election of a Deferral shall similarly continue in effect and shall be treated as a separate, new election with respect to each Plan Year to which it applies, and shall be accounted for separately.

ACCOUNTS AND ALLOCATIONS

4.01 Deferred Amounts: Each Eligible Participant’s Deferred Amounts shall be credited to a Book Account established for such Eligible Participant as soon as administratively practicable after such Deferred Amounts are earned.

4.03 Vested Interest: Each Participant shall always be fully vested in such Participant’s entire Accrued Amount.

ARTICLE 5

DISTRIBUTIONS

(a) Payout Method 1: A period of years equal to the number of years in which a Participant actively deferred compensation pursuant to a deferred compensation agreement executed on or before December 31, 1999. For any Participant who elected this method of determining annual installment distributions with respect to deferral under an individual deferred compensation agreement for calendar year 1999 or any prior calendar year, annual installments will be distributed for the number of calendar years (whole or partial) for which the Participant elected to defer $1 or more of Compensation hereunder, determined as of the date the distribution of the Participant’s Accrued Amount is to commence.

(b) Payout Method 2: A period of years not in excess of ten (10) years with payment to commence in January of the calendar year following the calendar year which includes the Participant’s Termination Date. For all deferral elections for Plan Years starting on or after January 1, 2002, the ten (10) year limitation described above is changed to fifteen (15) years.

(c) Payout Method 3: A period of years not in excess of ten (10) years with payment to commence in January of any future year which is not later than the 10^th year following the calendar year of deferral. For distribution purposes, the “Calendar Year of Deferral” is defined as the calendar year in which Compensation would have been paid.

For Compensation earned in Plan Years beginning on or before January 1, 2004, a Participant may elect different periods with respect to the portion of his or her Accrued Amount attributable to each of his or her separate sub-accounts. For Compensation earned in Plan Years beginning on or after January 1, 2005, a Participant may make only a single Distribution Election each Plan Year. Each such Distribution Election shall apply to all earnings attributable to the Plan Year for all sub-accounts.

Distributions will be made to the Participant or, if the Participant is deceased, to the Participant’s Designated Beneficiary. The method of distribution must be elected when the Participant’s initial Election of Deferral for each year is executed. The Distribution Election is irrevocable by the Participant; provided, however, that the Administrator, in its sole discretion, may change the Distribution Election to another acceptable method under the Plan. It is provided further, that any Participant who elected distributions pursuant to section 5.01(a) may choose, at any time, to limit the period over which distributions would be made pursuant to such section, to the number of years such election has been in effect at the time of such choice.

If there is no valid distribution election, the distribution of the Participant’s Accrued Amount shall be made pursuant to section 5.01(b) in ten (10) annual installments.

Methods of distribution elected pursuant to individual deferred compensation agreements in effect prior to January 1, 2000, shall remain in effect with respect to each Participant’s sub-account, if any, which relates to deferrals under any such agreement.

5.02 Time of Distribution: At the time of his or her Election to Defer, Participant may elect to have payment of his or her Accrued Amount commence (a) in January of the calendar year following his or her Termination Date, Payout Method #1 or Payout Method #2 or (b) in January of any future year which is not later than the tenth year following the year of the deferral, Payout Method #3.

5.03 Payment Timing and Process: As elected by the Participant, the Companies shall commence payment of the Participant’s Accrued Amount as soon as administratively practicable, in accordance with the distribution method elected by the Participant. Notwithstanding the foregoing, amounts deferred pursuant to individual deferred compensation agreements in effect prior to January 1, 2000, shall be distributed commencing in January of the calendar year following the calendar year of the Participant’s Termination Date.

Except for the final payment from the Account Balance or the balance of a specific sub-account, the amount of each annual installment shall be determined by dividing the Participant’s Book Account Balance or the balance of each sub-account with respect to which a distribution is to be made, as of November 30^th of the preceding Plan Year, by the number of installments remaining to be paid. A final payment from the Account Balance or the balance of a specific sub-account (relating to a particular Plan Year’s deferral), shall be determined by taking the Account Balance or sub-account amount as of December 31^st of the preceding Plan Year and crediting earnings from that date through the date of distribution at the rate that would have been earned had such payment amount been invested in the Nationwide GIC during such period.

5.04 Small Amounts: Notwithstanding the foregoing provisions, if the Administrator determines that the value of the Participant’s Accrued Amounts, as of November 30^th of any year is $5,000 or less, his or her Accrued Amounts, determined as of such date will be paid to the Participant immediately.

5.05 Hardship Distribution: Notwithstanding any other provision herein, a Participant or Beneficiary may request from the Administrator an immediate distribution of all or some portion of his or her Accrued Amount as a Hardship Distribution. If the Administrator approves such request, then a single cash lump sum shall be distributed, in the amount necessary to meet the terms of the hardship, as soon as administratively practicable.

5.06 Elective Distribution: Notwithstanding any other provision herein, a Participant or Beneficiary may request from the Administrator am immediate distribution of all or some

portion of his or her Accrued Amount, if such amount is attributable to amounts deferred on or before December 31, 2004. If the Administrator approves such request, then a single cash sum shall be distributed in the amount requested, less 10% forfeiture, as soon as administratively practical.

5.07 Death Benefit Payments: Upon receipt by the Administrator of due proof of the death of a Participant, the value of the decedent’s account held hereunder shall be paid to the designated beneficiary of the decedent, or to the administrator or executor of the estate of the decedent if no valid beneficiary designation is in effect upon the death of the decedent.

A Participant may name more than one beneficiary. Each beneficiary shall be paid the portion of the Participant’s Accrued Amount that the Participant specifies for each person. If the Participant does not specify amounts, the Accrued Amount shall be divided equally among the surviving primary beneficiaries. If any of the named primary beneficiaries dies before the Participant dies, the deceased beneficiary’s portion shall be divided equally among the surviving primary beneficiaries unless the Participant specifies otherwise. If there is no surviving primary beneficiary, the total amount shall be divided equally among the surviving contingent beneficiaries, unless the Participant specifies otherwise. If there are no surviving contingent beneficiaries, the deceased primary beneficiary’s designated portion of the total amount payable shall be paid to the Participant’s estate.

If the Participant failed to properly designate a beneficiary, the Participant’s Accrued Amount shall be distributed to the following parties, in the following order: the Participant’s surviving spouse, if any; if the Participant has no surviving spouse, the Participant’s surviving children, if any, equally; if the Participant has no surviving spouse or surviving children, the Participant’s surviving parents, if any, equally; if none of the preceding parties is living, the Participant’s surviving siblings, if any, equally; and, if none of the preceding parties survive the Participant, to the Participant’s estate.

If the designated beneficiary of a decedent is a minor with respect to whom a guardian has been appointed, and if such guardian refuses to accept the payment due such beneficiary hereunder, or if there is no guardian, the Administrator shall direct that such payment be made to the estate of the decedent in full discharge of the liability of the Company to the extent thereof.
