     "5.06   Transfer Between Investment Funds.  A Member, Inactive Member or
     Former Member may elect to transfer the Asset Balance of his Accounts in
     whole percentage amounts from any or all Investment Funds to any or all
     other Investment Funds; provided that immediately after such transfer,
     the total Asset Balance of the Accounts of the Member, Inactive Member or
     Former Member under Fund A shall not exceed fifty percent (50%) of the
     total Asset Balance of all the Accounts of the Member, Inactive Member or

     with the Savings Plan Board to accept his rollover contribution.  Any
     such request shall state the amount of the Rollover Contribution and
     include a statement that such contribution constitutes a Rollover
     Contribution.

     The Savings Plan Board shall determine in accordance with a uniform and
     nondiscriminatory policy, whether or not such contribution originated
     from a plan qualified under Section 401(a) of the Code, and may require
     such Employee to submit such other evidence and documentation as it deems
     necessary.

     All Rollover Contributions must be in cash and the amount contributed
     under the Plan and any subsequent investment experience on such
     contributions shall be credited to the Employee's Rollover Account.

     For purposes of this Section 5.17, a Rollover Contribution means a
     rollover of an "eligible rollover distribution" as defined in Section
     402(c)(4) of the Code from a qualified plan or a distribution from a
     conduit Individual Retirement Account."
