     THIS SECOND AMENDMENT TO LOAN AND SECURITY AGREEMENT (the "Amendment")
is dated as of December 1, 1995, and entered into by and between BANKAMERICA

Security Agreement dated December 12, 1994, as amended by that certain First
Amendment to Loan and Security Agreement dated as of August 17, 1995 (the
"Agreement"); 

     WHEREAS, Lender and Borrower desire to further amend the Agreement as
hereinafter set forth;

     NOW, THEREFORE, in consideration of the mutual conditions and agreements
set forth in the Agreement and this Amendment, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
the parties, intending to be legally bound, hereby agree as follows:

                                 ARTICLE I
                                 ---------     
                                Definitions

     Section 1.01.  Definitions.  Capitalized terms used in this Amendment,
to the extent not otherwise defined herein, shall have the same meanings as in
the Agreement, as amended hereby.


                                ARTICLE II
                                ----------
                                Amendments

     Section 2.01.  Amendment to Section 3.1(a) of the Agreement. 
Subsections (i) and (ii) of Section 3.1(a) of the Agreement are hereby amended
to read in their entirety as follows:

           (i) For all amounts charged as Revolving Loans other than
     Eurodollar Rate Loans, including all Revolving Loans which are Reference
     Rate Loans, then at a fluctuating per annum rate equal to one percent
     (1%) per annum (the  Reference Rate Margin ) plus the Reference Rate;
     and

           (ii)     If the Revolving Loans are Eurodollar Rate Loans, then at a
     per annum rate equal to: three and three-eighths percent (3.375%) per
     annum (the  Eurodollar Margin ) plus the Eurodollar Rate determined for
     the applicable Interest Period.

     Notwithstanding the foregoing, if Adjusted Tangible Net Worth equals or
     exceeds $89,500,000, as reflected on Borrower s most current quarterly
     Financial Statements provided no Event of Default is outstanding, then
     for so long as Adjusted Tangible Net Worth is at least $89,500,000, both
     the Reference Rate Margin and the Eurodollar Margin with respect to the
     Revolving Loans other than the Short Term Revolving Loans will be
     reduced by one-half of one percent (.50%), and the reduction will be
     effective as of the first day of the month following receipt by Lender
     of the Financial Statements.

     Each change in the Reference Rate shall be reflected in the interest
     rate described in (i) above as of the effective date of such change. 
     All interest charges shall be computed on the basis of a year of three
     hundred sixty (360) days and actual days elapsed.  Except as otherwise
     provided herein, (1) interest accrued on each Eurodollar Rate Loan shall
     be payable in arrears on each Eurodollar Interest Payment Date
     applicable to such Eurodollar Rate Loan and upon payment thereof in
     full, and (2) interest accrued on the Reference Rate Loans will be
     payable in arrears on the first day of each month hereafter. 
 
The remaining provisions of Section 3.1(a) are unchanged.

     Section 2.02.  Amendment to Section 9.16 of the Agreement.  Section
9.16 is hereby amended to read in its entirety as follows:

           9.16     Adjusted Tangible Net Worth.  Adjusted Tangible Net Worth
     (without taking into account any purchases of treasury stock) will not
     be less than the following amounts at the end of each of the Fiscal
