               (c) notify Lockheed Martin of the estimated amount of the sum of
     electronic payments as of the date of transfer not later than 1:00 p.m.
     Eastern Standard Time on the date of such transfers;

               (d) provide Lockheed Martin with  projections of cash flow and

     agreement or arrangement; and

               (f) disburse funds from the Concentration Account to banks and
     accounts approved by Lockheed Martin.

     Nothing in this Agreement is intended to limit the purposes for which
CalComp Technology may make payments or restrict its ability to make
investments.

          4.     Investments.  (a) In the event that CalComp Technology's net
                 -----------                                                 
cash balance in the Concentration Account on any banking day is greater than
zero, Lockheed Martin will cause the cash balance to be transferred from the
Concentration Account to an account of Lockheed Martin.  That amount will,
first, be deemed a repayment of principal of Base Rate Loans outstanding under
the Revolving Credit Agreement, second, to the extent not applied to repay Base
Rate Loans, be deemed a repayment of principal of LIBOR Rate Loans outstanding
under the Revolving Credit Agreement, and, third, to the extent not applied to
repay Base Rate Loans and LIBOR Rate Loans, be deemed a repayment of outstanding
Advances and, fourth, to the extent not applied to repay loans or Advances, be
deemed an Investment held by Lockheed Martin for the benefit of CalComp
Technology.

          (b) Lockheed Martin will pay CalComp Technology interest on the
aggregate principal amount of Investments at a rate per annum equal to the
Federal Funds Rate and will make available to CalComp Technology the aggregate
principal amount of such Investments plus interest accrued not later than the
next business day.  The aggregate amount of Investments plus interest accrued
thereon at any time shall be available to off-set any negative cash balances in
the Concentration Account on any day.

          5.     Advances.  (a) In the event that CalComp Technology's net cash
                 --------                                                      
balance in the Concentration Account on any banking day is negative, Lockheed
Martin will, subject to Section 5(c) hereof, advance by a deposit of funds into
the Concentration Account the amount necessary to cause the balance in the
Concentration Account to be zero.  The amount so advanced will, first, be deemed
a repayment of any Investments plus any interest accrued thereon outstanding on
the date thereof and, second, to the extent not applied to repay Investments, be
deemed an Advance by Lockheed Martin to CalComp Technology.

          (b) CalComp Technology will pay Lockheed Martin interest on Advances
at a per annum rate equal to the Federal Funds Rate.

          (c) The maximum principal amount of Advances to be made by Lockheed
Martin hereunder shall be $2,000,000 outstanding at any time.

          6.     Interest.  All interest to be paid with respect to Investments
                 --------                                                      
or Advances will be calculated on the basis of a 365/366 day year and the actual
number of days elapsed.  Interest will be calculated on each banking day and
will be payable monthly in arrears.  Lockheed Martin will notify CalComp
Technology, not later than ten days after the end of each month, of the net
interest amount payable by or to CalComp Technology hereunder with respect to
Investments and Advances, which amount will be payable by the applicable party
within five banking days of the date of such notice.

          7.     Additional Accounts.  CalComp Technology may establish petty
                 -------------------                                         
cash accounts and local depository accounts at local banks to ensure that funds
are available to cover minor operating expenses.  Such accounts, however, shall
be subject to a limit on the maximum balances therein reasonably approved by
Lockheed Martin and shall be replenished only to the extent vouchers and
receipts are available.  CalComp Technology may further establish bank accounts
in international locations as are required to collect and disburse funds of
foreign operations.  Such foreign bank accounts shall be established and banks
approved by Lockheed Martin.

          8.     Compensation.  Lockheed Martin shall be compensated for
