11.  TERM, TERMINATION, EVENT OF DEFAULT - This Agreement shall continue for an
     initial term of two (2) years form the date first executed and may be
     canceled by either party upon ninety (90) days written notice of
     termination to the other party.  Notwithstanding the foregoing, the Bank
     may terminate this Agreement effective immediately, if the Bank's decision
     is a result of an order by a court or regulator, or is made as a result of
     litigation, challenging the offering of this service in which the Bank is a
     party defendant.  
     
     During the term of this Agreement, the Bank will not offer or promote the
     services contemplated by 

<PAGE>

     the Agreement through or by any broker or similar provider other than RHI.
     
     In the event of termination of this Agreement, RHI agrees to release to the
     Bank, at the Bank's request, all information the Bank may reasonably
     require to continue servicing such Customers.  RHI may notify and service
     the Bank's Customers, if the Bank terminates the service contemplated by
     this Agreement, and the Bank does not, within ninety (90) days thereafter,
     provide or arrange for similar services to be provided to its Customers.  
     
     Customers may terminate their accounts at any time. 
     
     In the event of a challenge by a regulatory body, individual, or other
     entity relating to the legality of the performance, by either party, of its
     obligations under the provisions of the Agreement, which challenge may
     impact the ability  to make payments to the Bank hereunder, then the
     amounts which would have been paid to the Bank hereunder shall be held in
     escrow by RHI, pending resolution of such challenge.  If the making of such
     challenge is terminated by a settlement agreement, which does not preclude
     or limit the making of such payments, such escrow funds will be paid over
     to the Bank, with interest; the escrow funds are to be invested in an
     account at any federally insured national bank.  If the making of such
     payment is ultimately determined to be impermissible, or is precluded or
     limited pursuant to a settlement agreement relating to such challenge, such
     amounts shall be retained by RHI; and the parties hereto shall discuss the
     disposition of such amounts, consistent with the original intent of this
     Agreement, and the determination of impermissibility of settlement.  
     
12.  MISCELLANEOUS - Neither the Bank nor RHI shall hold itself out as an agent
     of the other, or any of the subsidiaries, or the companies controlled
     directly or indirectly by, or affiliated with, the other. 
     
     Neither the Bank nor RHI shall, without having obtained prior approval of
     the other, (which approval shall not be unreasonably withheld), distribute
     solicitation material, place or agree to place any advertisement in any
     manner that makes reference to the other and/or any of the services
     embodied in this Agreement.  
     
     This Agreement shall inure to the benefit of, and be binding upon, the
     successors and assignees of the parties hereto.  This Agreement may not be
     assigned by any party without the prior written consent of the other
     parties.  Neither this Agreement, nor activity hereunder, is intended to be
     and shall not be treated as, a general or limited partnership, association
     or joint venture.  
     
     Neither party hereto shall use any service mark, trade name, or trademark
     of the other party without the prior written consent of the other, which
     consent shall not be unreasonably withheld.  
     
     Each party shall have the exclusive right to any such name or mark
     developed by it in connection with services performed by it under this
     Agreement.
