     1.  CAPITALIZATION OF INTEREST. ELX: (A) acknowledges and agrees that,
effective from and after this day, the Unpaid Interest is added to the principal

indebtedness to ELXSI Corp. under the ELX->ELXSI Corp. Note in the aggregate
amount of $1,472,074.

     2.  EXTENSION. ELXSI Corp. hereby agrees that the "Maturity Date" under
(and as defined in) the ELX->ELXSI Corp. Note is hereby further extended by
three years, to December 8, 2003. The foregoing shall for all purposes be
effective as an amendment of the ELX->ELXSI Corp. Note. Accordingly, in the
event that ELXSI Corp. wishes to assign or otherwise transfer the ELX->ELXSI
Corp. Note to any third party, ELXSI Corp. shall advise such third party of such
amendment, and/or take such other reasonable actions, as may be reasonably
necessary, in order to render such amendment binding and effective on such third
party.

     3.  FURTHER ASSURANCES. From time to time after the date hereof, as and
when requested by either party hereto, the other party hereto shall execute and
deliver, or cause to be executed and delivered, such documents and instruments
and shall take, or cause to be taken, such further or other actions as such
requesting party may reasonably deem necessary or desirable in order to further
effect or evidence the transactions contemplated hereby or to otherwise carry
out the intent and purposes of this agreement.

     4.  GOVERNING LAW. This agreement shall be interpreted, construed and
enforced in accordance with the laws of the State of New York.
