a default under any term of any agreement, judgment, injunction, order, decree, law, regulation or arrangement to which Stockholder is a party or by which Stockholder (or any of Stockholder’s assets) is bound, except for any such breach,
violation, conflict or default which, individually or in the aggregate, would not impair or adversely affect Stockholder’s ability to perform Stockholder’s obligations under this Agreement or render inaccurate any of the representations
made by Stockholder herein.

 8. Exchange of Shares;
Waiver of Rights of Appraisal. If the Merger is consummated, the Shares shall, pursuant to the terms of the Merger Agreement, be exchanged for the consideration provided in the Merger Agreement. Stockholder hereby waives, and agrees to prevent

assigns, shall be brought and determined exclusively in the Massachusetts Superior Court and any state appellate court therefrom within the Commonwealth of Massachusetts (or, if the Massachusetts Superior Court declines to accept jurisdiction over a
particular matter, any state or federal court within the Commonwealth of Massachusetts). Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and
unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts.
Each of the parties hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (i) any claim that it is not personally
subject to the jurisdiction of the above-named courts for any reason other than the failure to serve in accordance with this Section 10(d), (ii) any claim that it or its property is exempt or immune from jurisdiction of any such court or
from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by
applicable law, any claim that (A) the suit, action or proceeding in such court is brought in an inconvenient forum, (B) the venue of such suit, action or proceeding is improper or (C) this Agreement, or the subject mater hereof, may
not be enforced in or by such courts.

 (f) Attorneys’ Fees. In any action at law or suit in equity to enforce this Agreement or the
rights of any of the parties hereunder, the prevailing party in such action or suit shall be entitled to receive its reasonable attorneys’ fees and all other reasonable costs and expenses incurred in such action or suit. 
 (g) Assignment and Successors. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns, including, without limitation, Stockholder’s estate and heirs upon the death of Stockholder, provided that except as otherwise specifically provided herein, neither this Agreement
nor any of the rights, interests or obligations of the parties hereto may be assigned by any of the parties hereto without prior written consent of the other parties hereto except that Credence, without obtaining the consent of any other party
hereto, shall be entitled to assign this Agreement or all or any of its rights or obligations hereunder to any one or more of its Affiliates. No assignment by Credence under this Section 10(g) shall relieve Credence of its obligations under
this Agreement. Any assignment in violation of the foregoing shall be void and of no effect.

this Agreement, express or implied, is intended to or shall confer upon any Person (other than the parties hereto) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. 
 (i) Cooperation. Stockholder agrees to execute and deliver such further documents, certificates, agreements and instruments and to take such other
actions as may be reasonably requested by Credence to evidence or reflect the transactions contemplated by this Agreement and to carry out the intent and purpose of this Agreement. Stockholder hereby agrees that LTX and Credence may publish and
disclose in the Registration Statement (including all documents and schedules filed with the SEC), such Stockholder’s identity and ownership of Shares and the nature of such Stockholder’s commitments, arrangements and understandings under
this Agreement and may further file this Agreement as an Exhibit to the Registration Statement or in any other filing made by LTX or Credence with the SEC relating to the Proposed Transaction. 
 (j) Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions
of this Agreement will remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable. 
 (k) Time of Essence. With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence. 
 (l) Specific Performance; Injunctive Relief. The parties hereto acknowledge that LTX and Credence shall be irreparably harmed and that there shall
be no adequate remedy at law for a violation of any of the covenants or agreements of Stockholder set forth in this Agreement. Therefore, Stockholder hereby agrees that, in addition to any other remedies that may be available to LTX or Credence, as
applicable upon any such violation, such party shall have the right to enforce such covenants and agreements by specific performance, injunctive relief or by any other means available to such party at law or in equity without posting any bond or
other undertaking.
