|--------|------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | b) | the      Dollar Limitation set forth in paragraph (a), above, multiplied by the      ratio of 1) to 2), where: |
|--------|----|----------------------------------------------------------------------------------------------------------------|

|   | 1) | is      equal to annual amount of the immediately commencing straight life annuity      under the Plan at the Participant’s Annuity Starting Date ;      and |
|--------|----|--------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | 2) | is      equal to the annual amount of the immediately commencing straight life      annuity under the Plan at age 62. |

For purposes of determining the present value of the      accrued benefit of any Employee or the amount of an account of any      Employee, distributions made with respect to such Employee under the Plan      (and any plan aggregated with the Plan under Section 416(g)(2) of the      Code) during the one-year period ending on the Determination Date must be      included.  The preceding sentence shall apply to distributions      under a terminated plan which, had it not been terminated, would have been      aggregated with the Plan under Section 416(g)(2)(A)(i) of the      Code.  In the case of a distribution made for a reason other      than severance from employment, death or disability, this provision shall      be applied by substituting five-year period for one-year      period.  The accrued benefits and accounts of an individual who      has not performed services for the Employer during the one-year period      ending on the Determination Date shall not be taken into      account. |

The Employer may permit any plan not required to      be included in an aggregation group as being part of such group if such      group would continue to meet the qualification requirements of Code      Section 401(a)(4) and the minimum participation standards of Code Section      410. |
