        surrender value of the Policy, this Agreement shall continue until
        terminated pursuant to Paragraph 8; however, the Employer's obligation
        to pay the Policy premiums pursuant to Paragraph 3.a shall cease

                             ASSIGNMENT AGREEMENT


          THIS ASSIGNMENT AGREEMENT is entered into and effective this  
9th day of December 1998, by and between (i) IMPERIAL BANCORP, a California 
- ---

ALIDA GRAZIADIO CALVILLO, Trustees, of the GRAZIADIO DYNASTY TRUST II,
dated December 9, 1998 ("Trust"),.
      ----------

          WHEREAS George L. Graziadio, Jr. ("Employee") is a valued employee
of Employer; and

          WHEREAS the Employer desires to provide the Employee with a 
split-dollar life insurance arrangement by assigning the Policy to the Trust and
paying certain parts of some of the annual premiums due on the Policy 
("Advances"), as more specifically provided for in that certain Split-Dollar 
Life Insurance Agreement("Agreement"), dated as of December 9, 1998,
                                                   ----------
entered into by and among the Trust, the Employee, Reva, and the Assignor; and 

          WHEREAS, in consideration of the Employer's making of the Advances and
of Employer's assignment of the policy to the Trust, the Trust has agreed to 
grant Employer a security interest in the Policy as collateral security for the 
repayment of the Advances.

          NOW, THEREFORE, for value received, the undersigned Employer hereby 
assigns, transfers and sets over to the Trust, all of its right title and 
interest in the policy, while the Trust assigns back to the Employer, its 
successors and assigns the following specific rights in the Policy, subject to 
the following terms and conditions:

      1.  OTHER DEFINITIONS.  Capitalized terms shall have the meanings set 
          -----------------
forth herein or as provided in the Agreement.  The assignment by the Trust to 
the Employer is referred to herein as the Collateral Assignment.

      2.  ASSIGNMENT.  This Collateral Assignment is made, and the Policy is to 
          ----------
be held, as collateral security to secure performance of all the obligations of 
the Trust to the Employer, either now existing or that may hereafter arise, 
pursuant to the terms of the Agreement.

      3.  LIMITATIONS.  The Employer's interest in the policy shall be as 
          -----------
follows:
 



          a.   Surrender or Cancellation.  If the Policy is surrendered during 
               -------------------------
     the term of the Agreement, the right to receive an amount equal to the
     greater of (i) the Advances as of the date of surrender, or (ii) the cash
     surrender value of the Policy as of the date of surrender, less reimbursed
     Advances.

               (i)      The Employer retains the power and authority to borrow
          from the Insurer, in the name of the Trust, the amount payable under
          the Agreement (including amounts due under Paragraph 10 of the
          Agreement), and to pledge or otherwise encumber the Policy to ensure
          repayment of the loan. The Employer shall have the right to receive
          the loan proceeds and shall have no obligation to make any payments on
          the loan.

               (ii)     To Employer shall not have the authority to cancel or 
          surrender the policy.

          b.   DEATH BENEFIT. If the Agreement is in effect upon the death of
               -------------  
     the Survivor, the right to receive an amount equal to:
      
               (i)      The Advances as of the date of the Survivor's death,
          plus

               (ii)     $120,000.

          c.   INCIDENTS OF OWNERSHIP.  Except as specifically retained by the 
               ----------------------
     Employer herein or in the Agreement, the Trust shall have all incidents
     of ownership in the Policy, including but not limited to:

               (i)      To name the Policy beneficiary, subject to Employer's
          interest in the Policy as determined pursuant to Paragraph 5.b of the
          Agreement.
     
               (ii)     The right further to assign its interest in the Policy;

               (iii)    The right to change the beneficiary of that portion of
          the proceeds to which it is entitled under Paragraph 5 of the
          Agreement; and

               (iv)     The right to exercise all settlement options permitted 
          by the terms of the Policy, provided, however, that all rights
          assigned to the Trust shall be subject to the terms and conditions of
          the Agreement.

     4.   ENDORSEMENT.  The Employer shall, upon request, forward the Policy to 
          -----------
the Insurer without unreasonable delay, for any designation or change of 
beneficiary, for any election of optional mode of settlement, or for the 
exercise of any other right granted to the Trust hereunder.

     5.   EMPLOYER'S RIGHT.  The Insurer is hereby authorized to recognize the 
          ----------------
Employer's claims to rights hereunder without investigating the reason for any 
action taken by the Employer, the validity or amount of any of the liabilities 
of the Trust to the Employer under

                                       2

 
the Agreement, the existence of any default therein, the giving of any notice 
required herein, or the application to be made by the Employer of any amounts to
be paid to the Employer. The signature of the Employer shall be sufficient for 
the exercise of any rights under the Policy assigned hereby to the Employer and 
the receipt of the Employer for any sum received by it shaft be a discharge and 
release therefore to the Insurer.

     6.  REASSIGNMENT. Upon receiving full payment for its interest in the 
         ------------
Policy pursuant to the Agreement, the Employer shall reassign to the Trust the 
Policy any all specific rights retained by it under this Collateral Assignment.

     7.  CONFLICT. In the event of any conflict between the provisions of this 
         --------
Assignment Agreement and the Agreement, or any other evidence of any liability 
with respect to the Policy or the rights of collateral security herein, the 
provisions of this Assignment Agreement shall prevail, as to the Insurer, and 
the Agreement shall prevail between the Parties thereto.

     8.  ASSIGNMENT FOR SECURITY. It is the intent of the undersigned that the 
         -----------------------
assignment to the Trust makes the Trust the owner of the policy and the holder 
of all incidents of ownership, as defined in Treasury Regulation (S)(S) 
20.2042-1(c)(2)-(6), in the Policy, and that the Collateral Assignment assign an
interest in proceeds becoming payable under the Policy as security for the 
Employer's Interest without granting to Employer any such incidents, and it is 
agreed that this Assignment Agreement shall be construed so as to accomplish 
this intent.

          IN WITNESS WHEREOF the Parties have executed this Assignment Agreement
as of the day and year first above written.
