                                  SUPPLEMENT A
                                       TO
                              AMENDED AND RESTATED
                           LOAN AND SECURITY AGREEMENT


                     Dated as of March 31, 2003, as amended,
                Between ELXSI, BICKFORD'S HOLDINGS COMPANY, INC.
                     BICKFORD'S FAMILY RESTAURANTS, INC. and
                              BANK OF AMERICA, N.A.

1.       Loan Agreement Reference. This Supplement A, as it may be amended or
modified from time to time, is a part of the Amended and Restated Loan and
Security Agreement, dated as of April 22, 2002, as amended by that certain First
Amendment to Amended and Restated Loan and Security Agreement dated as of August
5, 2002, that certain Second Amendment to Amended and Restated Loan and Security
Agreement dated as of December 30, 2002, that certain Third Amendment to Amended
and Restated Loan and Security Agreement dated as of January 31, 2003, and that
certain Fourth Amendment to Amended and Restated Loan and Security Agreement
dated as of March 31, 2003 between Borrower and Lender (the "Third Amendment")
(together with all amendments, restatements, supplements and other modifications
thereto, the "Loan Agreement"). Terms used and not defined herein which are
defined in the Loan Agreement shall have the meaning ascribed to them therein
unless the context requires otherwise. As used in this Supplement A,

         "EBITDA" means, as of the last day of any specified calendar month,
         Borrower's consolidated net earnings before interest expense,
         depreciation, amortization and provision for Taxes of the Borrower for
         the period from January 1, 2003 to and including the last day of such
         calendar month taking such period as one (1) accounting period. For
         purposes of this definition, (i) net earnings shall not include (x) any
         gains on the sale or other disposition of Investments (other than cash
         equivalents) or fixed assets and any extraordinary or nonrecurring
         items of income for the period to the extent that the aggregate of all
         such gains and extraordinary or nonrecurring items of income exceeds
         the aggregate of losses on such sales or other dispositions and
         extraordinary or nonrecurring charges during such period and (y) the
         aggregate amount of interest income earned after December 31, 2002 and
         included as income during such period, (ii) net earnings will be
         calculated without the effect of a reduction for fees paid by the
         Borrower to Lender as required under any amendment to the Loan
         Agreement, and (iii) interest expense shall include, without
         limitation, implicit interest expense on Capitalized Leases.
         Notwithstanding the foregoing, EBITDA shall be determined without
         giving effect to any reserve established, or increase or decrease
         thereof, for Fiscal Year 2002, or for any period thereafter.

         "Net Worth" means on the last day of any specified fiscal quarter, the
         consolidated net equity of the Borrower calculated in accordance with
         GAAP.

                                        7

                           December 31, 2003             $51,081,000

                  The Net Worth covenants provided above are calculated using a
                  deferred tax asset as of December 31, 2002 of $22,997,000. If
                  the amount of the tax deferred asset during 2003 is revised,
                  then the Net Worth covenants shall be revised to increase (in
                  the event the tax deferred asset increases) or decrease (in
                  the event the tax deferred asset decreases) in accordance with
                  the tax deferred asset revision.

                  SECTION 2.3 Capital Expenditures. Not, and not permit any
         Subsidiary to, purchase or otherwise acquire (including, without
         limitation, acquisition by way of Capitalized Lease), or commit to
         purchase or otherwise acquire, any fixed asset if, after giving effect
         to such purchase or other acquisition, (A) the aggregate capitalized
         cost of all fixed assets purchased or otherwise acquired (other than by
         means of a Capitalized Lease) by Borrower and its Subsidiaries on a
         consolidated basis plus (B) the aggregate annual payments under
         Capitalized Leases (excluding the portion thereof representing imputed
         interest) of Borrower and its Subsidiaries on a consolidated basis
         (excluding, in each of (A) and (B), any fixed asset which constitutes a
         replacement for an asset which was the subject of a casualty or
         governmental taking to the extent the purchase or other acquisition
         thereof is funded by insurance proceeds or other payments received as a
         result of such casualty or taking) would exceed $4,000,000 for Fiscal
         Year 2003 or for any Fiscal Year thereafter, on a non-cumulative basis.
