         d.   ( )  other _____


E10      LIMITATIONS ON ALLOCATIONS  (Plan Section 4.4)

         a.   If any Participant is or was covered under another qualified
              defined contribution plan maintained by the Employer, other than a
              Master or Prototype Plan, or if the Employer maintains a welfare
              benefit fund, as defined in Code Section 419(e), or an individual
              medical account, as defined in Code Section 415(l)(2), under which
              amounts are treated as Annual Additions with respect to any
              Participant in this Plan:



                                      -14-
   15

              1.   (X)  N/A.
              2.   ( )  The provisions of Section 4.4(b) of the Plan will apply
                        as if the other plan were a Master or Prototype Plan.
              3.   ( )  Provide the method under which the Plans will limit
                        total Annual Additions to the Maximum Permissible
                        Amount, and will properly reduce any Excess Amounts, in
                        a manner that precludes Employer discretion.

         b.   If any Participant is or ever has been a Participant in a defined
              benefit plan maintained by the Employer:

              1.   (X)  N/A.
              2.   ( )  In any Limitation Year, the Annual Additions credited to
                        the Participant under this Plan may not cause the sum of
                        the Defined Benefit Plan Fraction and the Defined
                        Contribution Fraction to exceed 1.0. If the Employer's
                        contribution that would otherwise be made on the
                        Participant's behalf during the limitation year would
                        cause the 1.0 limitation to be exceeded, the rate of
                        contribution under this Plan will be reduced so that the
                        sum of the fractions equals 1.0. If the 1.0 limitation
                        is exceeded because of an Excess Amount, such Excess
                        Amount will be reduced in accordance with Section
                        4.4(a)(4) of the Plan. 
              3.   ( )  Provide the method under which the Plans involved will
                        satisfy the 1.0 limitation in a manner that precludes
                        Employer discretion.

     effective as of the following date:

     a.   For Plans not entitled to extended reliance as described in Revenue
          Ruling, 94-76, the first day of the first Plan Year beginning on or
          after December 31, 1994, of if later, 90 days after December 31, 1994,
          or

     b.   For Plans entitled to extended reliance as described in Revenue Ruling
          94-76, as of the first day of the first plan year beginning in 1999.
          However, in the event of a transfer of assets to the Plan from a money
          purchase plan that occurs after the date of the most recent
          determination letter, the effective date of the amendment shall be the
          date immediately preceding the date of such transfer of assets.

Transfer of Assets From a Money Purchase Plan

     Notwithstanding any provision of this plan to the contrary, to the extent
that any optional form of benefit under this plan permits a distribution prior
to the employee's retirement, death, disability or severance from employment,
and prior to plan termination, the optional form of benefit is not available
with respect to benefits attributable to assets (including the post-transfer
earnings thereon) and liabilities that are transferred, within the meaning of
Section 414(l) of the Internal Revenue Code, to this plan from a money purchase
pension plan qualified under 401(a) of the Internal Revenue Code (other than any
portion of those assets and liabilities attributable to voluntary employee
contributions).

Pursuant to the terms of the Plan regarding amendment, Wheat First Butcher
Singer, as sponsor of prototype, hereby adopts this amendment as of the date set
forth below.
