                                AMENDMENT NO. 1
                                       TO
                       LICENSE AND DEVELOPMENT AGREEMENT
 
     This Amendment No. 1 is entered into as of this      day of July, 1994 to
the License and Development Agreement (the "Agreement") and the Distribution and
Supply Agreement, each dated as of the 28th day of January, 1993 between LTX
Corporation ("Company") and Ando Electric Co., Ltd. ("Licensee").
 
                                   RECITALS:
 
     WHEREAS, The Company and Licensee desire to expand the scope of rights
under the Agreement to include a license to the AL60-100 Tester and AL100 Tester
(as such terms are defined in this Amendment), with modified rights as set forth
herein.
 
     NOW, THEREFORE, in connection of the premises and of the mutual promises
and covenants contained in this Amendment, the parties agree as follows:
 
     1.  The following definitions in Section 1.1 are amended in their entirety
as follows:
 
          " 'Ando-developed Company Improvements' shall mean any Improvement
     that Licensee or its Affiliates or subcontractors, solely and not jointly
     with Company or its Affiliates, may acquire, discover, invent, originate,
     make or conceive with respect to Licensed Technology which shall
     specifically include, without limitation, the AL 100 Tester."
 
          " 'Tester' shall mean all Delta 50 Testers designed, developed,
     manufactured or sold by the parties pursuant to this Agreement (whether or
     not any such Tester includes any proprietary computer software of the
     Company), including all Improvements and enhancements thereto, and
     including derivatives and versions of the Delta 50 Tester, the design,
     development, use or operation of which uses Licensed Technology (including
     the AL60-100 Tester and AL100 Tester)."
 
     The definition of Licensed Technology is amended by adding the following
sentence after the first sentence of said definition:
 
          "The Licensed Technology does not include any of the foregoing that
     relate to the Company's Delta 100 Tester, except to the extent that they
     are specifically necessary to design, develop, use, manufacture, have made,
     market, sell, lease, improve, repair or otherwise dispose of the Delta 50
     Tester."
 
     The following definitions are added to the Definitions in Section 1.1:
 
          " 'AL60-100 Tester' shall mean the Ando-designed Tester (under any
     names which Ando may sell such Tester) operating in the frequency of 60-100
     MHz, which exceeds the original speeds of 50 MHz or less, with the method
     of enhancement of the Licensed Technology embodied in the Delta 50 Tester
     set forth on Exhibit A to this Amendment."
 
          " 'AL100 Tester' shall mean the Ando-designed Tester (under any names
     which Ando may sell such Tester) equivalent to or exceeding the Company's
     Delta 100 Tester (as presently in existence, with general specifications as
     set forth on Exhibit B to this Amendment, and as modified in the future)
     using Ando's own design together with the Licensed Technology and which is
     not the AL60-100 Tester."
 
     2.  Section 2.1(a) is amended to delete from the last line of Section
2.1(a) words "which operate at speeds equal to or less than 50MHz."
 
     Section 2.1(b) is amended to add the following to the end of the last
sentence:
 
          ". . .; provided, however, that the Company agrees to provide prior
     notice to Licensee of the Company's decision to utilize the manufacturing
     rights retained by the Company under Section 2.1(a) or this Section 2.1(b)
     or granted to the Company under Section 2.2 or Section 4.4."
   2
 
     3.  Section 3.1 is amended to add the following sentence:
 
          "Promptly following the execution of Amendment No. 1, the Company
     agrees to deliver to Licensee all documentation of the Licensed Technology
     in its possession relating to the enhancement of the Delta 5100 Tester set
     forth on Exhibit A to this Amendment which is necessary for the development
     by Ando of the AL60-100 Tester. Delivery of documentation does not include
     documentation of technology relating solely to the Company's Delta 100 test
     system."
 
     4.  The definition of "Tester" in Section 1 of the Distribution and Supply
Agreement is amended in its entirety as follows:
 
          " 'Tester' shall mean all Delta 50 Testers manufactured and sold by
     Ando pursuant to the License Agreement and this Agreement (whether or not
     any such Delta 50 Tester includes any proprietary computer software of
     LTX), including all improvements and enhancements as the parties may agree,
     and including all lower frequency derivatives and versions of the Delta 50
     Tester, the design, development, use or operation of which uses technology
     licensed by LTX to Ando under the License Agreement (including the AL60-100
     Tester and AL100 Tester, as such terms are defined in Amendment No. 1 to
     the License Agreement)."
 
     5.  The representation and warranties set forth in Section 5.3 with regard
to the Agreement, as amended by this Amendment No. 1, are reaffirmed as of the
date of this Amendment No. 1.
 
     6.  Except as amended by this Amendment No. 1, the Agreement and the
Distribution and Supply Agreement shall remain in full force and effect.
 
     IN WITNESS WHEREOF, the parties have caused this Agreement to be executed
by their duly authorized representatives as of the date set forth above.
