<PAGE>   17


material breach of Section 7.3(a) of this Agreement, which breach
continued unremedied for ninety (90) days, and that Ando is not in material
breach of this Agreement;

               (iii) if LTX shall make an assignment for the benefit of
creditors or a receiver shall be appointed for its business or properties, of if
any bona fide petition shall be filed by or against it under any provisions of
any bankruptcy, insolvency or similar laws and the same has not been dismissed
within (60) days after filing.

If the Escrow Materials are released under clause (iii) above, in the case of
proceeding under Chapter 11 of the United States Bankruptcy Code, then, so long
as LTX continues to perform or is able to perform its obligations under Section
7.3(a) of this Agreement, Ando shall continue to make all payments under Section
7 and 8.2(f).

     LTX represents and warrants and covenants to Ando that (i) the Escrow
Materials to be provided to the Escrow Agent constitute the source code form of
the enVision++ Software and any modifications as licensed to Ando pursuant to
this Agreement and (ii) the Escrow Materials to be delivered to the Escrow Agent
will be in a form suitable for production by computer and/or photocopy
equipment. Notwithstanding the foregoing, Ando acknowledges that, in order to
maintain and enhance the Escrow Materials, a third programmer or analyst may
require use of a reference to other publicly available software, routines and
techniques, and assistance from LTX with respect to specific techniques and
algorithms. LTX represents and warrants and covenants that it will supplement
the Escrow Materials delivered hereunder with all revisions, corrections, and
enhancements or other changes in a timely manner, but no more often than two (2)
times per year, so that the Escrow Materials continue to constitute the human
readable program for the current release of each portion of the Source Code. Any
Escrow Materials released to Ando shall be used by Ando exclusively for the
purposes of supplying, supporting and maintaining enVision++ Software for Fusion
Test Systems manufactured by Ando and used by Ando or Ando's customers.

Tokyo interbank rate for United States Dollars and for the respective invoiced
currency in effect at the close of business on the last working day of the
quarter during which the sales have been effected, or in the event that there is
no such official rate of exchange on such date, at the mean of the buying and
selling rates of exchange on such date as quoted by Citibank, N.A., at such
bank's principal offices in New York, New York, United States of America.

               (d) Ando shall keep full and accurate records adequate to enable
LTX to verify Ando's Net Sales and all payments required to be paid to LTX
pursuant to Section 8.2 and shall allow LTX to review and audit (at LTX's cost)
such records by an independent certified public accounting firm reasonably
acceptable to Ando upon reasonable notice and during business hours not
unreasonably interfering with Ando's business. In the event that such audit
reveals a variance in excess of ten percent (10%) of Net Sales, Ando shall pay
all costs associated with LTX's audit.

               (e) In respect of all payments under this Agreement which are not
made to LTX by Ando when due, Ando shall pay to LTX on demand (whether before or
after judgment) a daily charge computed at the rate of 1 and 1/2% per month or,
if less, the maximum interest rate payable under the laws of the relevant
jurisdiction on the amount from time to time overdue.

               (f) With respect to each sublicense of enVision++ Software
distributed through Ando, Ando will pay software license fees to LTX or its
Affiliates in an amount to be agreed to by the parties in the Software Licensing
and Distribution Agreement. Ando will also pay to LTX each year an agreed to
amount for the then effective annual software support services fees with respect
to all enVision++ Software distributed by Ando and used at such time by such
sublicensees. All of such fees shall be paid at the same time and in the same
manner as royalties under Section 8.2(a) and shall be subject to the same
reporting obligations and audit rights as are set forth above in Section 8.2.

     8.3 TAXES. The consideration payable under Sections 8.1 and 8.2 (including
the cash payments and stock certificates) is net of taxes and Ando shall be
responsible for all taxes, withholdings, deductions, levies, and assessments of
any nature on such payments now or hereafter imposed or levied by any national,
federal, state or local government or any political subdivision thereof or
taxing or other authority excepting taxes based on the net income of LTX. LTX
will pay to Ando within thirty (30) days after LTX files a tax return using a
tax credit, the amount of any incremental benefit actually realized by LTX, from
use of tax credits resulting from Ando's payment of withholding tax in Japan on
the consideration payable under Sections 8.1 and 8.2 of this Agreement. In the
event such incremental benefit is disallowed by a taxing authority, Ando agrees
that it shall pay within thirty (30) days after LTX provides notice to Ando of
the same (which notice shall include substantiating documentation of such
disallowance), the amount of the payment previously paid by LTX to Ando. Upon
Ando's reasonable request, LTX shall provide Ando with a report describing LTX's
tax status with respect to its tax credits.

on a transfer price, which shall apply to both parties.

     9.3  ORDERS OF FUSION TEST SYSTEMS.

          (a) LTX and Ando shall provide each other with a forecast of
requirements for Fusion Test Systems to be supplied by the other party for the
Territory (the "Buying Plans"). The Buying Plans will be presented for fiscal
quarters based on a July 31 year end, over a nine-month period, and be updated
every quarter. An updated Buying Plan will be sent by each party before the
first month of each quarter so that it is received not later than the 15th day
of the month before the first month of the quarter, covering the following three
quarters. The Buying Plans shall be merely each party's good faith estimate and
shall not be binding upon either party.

          (b) All purchases for Fusion Test Systems by LTX or Ando, as the case
may be, or Affiliates shall be made pursuant to a System and Parts Supply
Agreement in a form substantially similar to the Prior Agreements and consistent
with the provisions of this Agreement, which the parties shall use their best
efforts to agree to within sixty (60) days after execution of this Agreement.

          (b) Ando shall have the right to make revisions, improvements and
modifications to any Mixed Signal Module (with respect to any specific Mixed
Signal Module, a "Mixed Signal Modification") to Fusion Test Systems if the same
shall have been requested by a customer of Ando (which such request shall be
provided promptly to LTX) AND LTX shall have informed Ando in a writing signed
by the President or the Senior Vice President of LTX, which writing shall not be
unreasonably delayed, that Ando will be granted the right to make the Mixed
Signal Modification because LTX is unwilling or unable to provide such Mixed
Signal Modification. Should LTX provide such a writing to Ando, it shall, within
a reasonable period of time thereafter, provide to Ando such LTX Mixed Signal
Technology as may be necessary to allow Ando to make such Mixed Signal
Modification, and the definition of LTX Licensed Technology will include such
LTX Mixed Signal Technology. Should LTX elect to not inform Ando, LTX shall use
its best efforts to develop and manufacture the Mixed Signal Modification within
the time period requested by such Ando customer, or, if such time period is not
commercially reasonable, within a commercially reasonable time period. The price
to Ando for any such Mixed Signal Modification developed and manufactured by LTX
shall be mutually agreed to by LTX and Ando.

     9.5 SUPPLY OF PARTS. In addition to the Mixed Signal Modules or Mixed
