12.3 LICENSEE’s Representations and Warranties.  LICENSEE represents and warrants that it has full corporate power and authority to enter into this Agreement, that this Agreement constitutes the binding legal obligation of LICENSEE and that execution and performance of this Agreement by LICENSEE will not violate, contravene or conflict with any other agreement to which LICENSEE is a party or by which it is bound or with any law, rule or regulation applicable to LICENSEE.

ARTICLE 14 - MISCELLANEOUS PROVISIONS

14.1 *** Confidential Treatment Requested as to this Information***

14.2 Negotiation Covenant.  AVANT agrees to enter into good faith negotiations with LICENSEE, at LICENSEE’s request, with respect to the terms of possible future non-exclusive licenses under the PATENT RIGHTS for LICENSEE to sell other products and/or in other fields of use.  AVANT may withhold consent to such future request by LICENSEE if the requested license or any term or condition thereof is not commercially reasonable based upon the then-current market conditions. The parties agree and acknowledge, however, that the successful conclusion of such negotiations is not a condition precedent or condition subsequent to the execution, delivery or performance of this Agreement.  Furthermore, until and unless AVANT and LICENSEE enter into any such definitive non-exclusive license, LICENSEE’s rights shall be limited to the express rights, and subject to the express limitations and conditions, set forth in this Agreement.

14.3 Compliance with Laws.  To the extent that any invention claimed in the PATENT RIGHTS has been partially funded by the United States Government, and only to the extent required by applicable laws and regulations, LICENSEE agrees that any LICENSED PRODUCTS used or sold in the United States will be manufactured substantially in the United States or its territories.  Current law provides that if a domestic manufacturer is not commercially feasible under the circumstances, AVANT agrees to exercise commercially reasonable efforts to obtain a waiver of this requirement from the relevant federal agency on behalf of LICENSEE and, upon LICENSEE’S request, shall cooperate with LICENSEE in seeking such a waiver.

14.4 Prohibition on Liens.  LICENSEE shall not create or incur or cause to be incurred or to exist any lien, encumbrance, pledge, charge, restriction or other security interest of any kind upon the PATENT RIGHTS.

14.5 Announcements.  Neither party shall originate any publicity, news release or other public announcement, written or oral, relating to this Agreement or the existence of an arrangement between the parties (“Announcements”), without the prior written approval of the other party, which approval shall not be unreasonably withheld or delayed, except as otherwise required by law.  The foregoing notwithstanding, AVANT and LICENSEE shall have the right to make such Announcements without the consent of the other party in any prospectus, offering memorandum, or other document or filing required by applicable securities laws or other applicable law or regulation, provided that such party shall have given the other party, as applicable, at least five (5) business days prior written notice of the proposed text for the purpose of giving the other party the opportunity to comment on such text.

14.6 No Implied Licenses.  No implied licenses are granted pursuant to the terms of this Agreement.  No licensed rights shall be created by implication or estoppel.

14.7 Relationship of the Parties.  Nothing in this Agreement shall be construed to place the parties hereto in an agency, employment, franchise, joint venture, or partnership relationship.  Neither party will have the authority to obligate or bind the other in any manner, and nothing herein contained shall give rise or is intended to give rise to any rights of any kind to any third parties.  Neither party will represent to the contrary, either expressly, implicitly or otherwise.

14.8 Marking Requirement.  To the extent commercially feasible, and consistent with prevailing business practices and applicable law, all LICENSED PRODUCTS sold pursuant to this Agreement will be marked with the number of each issued patent that applies to such LICENSED PRODUCTS.

14.9 Governing Law; Consent to Jurisdiction.  ALL DISPUTES, CLAIMS OR CONTROVERSIES ARISING OUT OF THIS AGREEMENT, OR THE NEGOTIATION, VALIDITY OR PERFORMANCE OF THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED HEREBY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS WITHOUT REGARD TO ITS RULES OF CONFLICT OF LAWS.  Each of the parties hereto irrevocably and unconditionally consents to the exclusive jurisdiction of J.A.M.S./Endispute, Inc. to resolve all disputes, claims or controversies arising out of or relating to this Agreement or any other agreement executed and delivered pursuant to this Agreement or the negotiation, validity or performance hereof and thereof or the transactions contemplated hereby and thereby and further consents to the jurisdiction of the courts of Massachusetts for the purposes of enforcing the arbitration provisions of Section 14.10 of this Agreement.  Each party further irrevocably waives any objection to proceeding before J.A.M.S./Endispute, Inc. has been brought in an inconvenient forum.  Each of the parties hereto hereby consents to services of process by registered mail at the address to which notices are to be given.  Each of the parties hereto agrees that its or his submission to jurisdiction and its or his consent to service of process by mail is made for the express benefit of the other parties hereto.

14.10 Arbitration.  If any dispute arises between the parties relating to or arising out of this Agreement, appropriate representatives of the parties shall first use commercially reasonable efforts to negotiate in good faith a resolution of the dispute as expeditiously as is reasonably possible. If the dispute is not resolved within thirty (30) days after the date that a party referred the matter to the other party via written notice invoking the relief contained within this section, the dispute shall be referred to binding arbitration under the rules of the J.A.M.S. / Endispute with such arbitration to be held in Boston, Massachusetts.  This Section 14.10 applies equally to requests for temporary, preliminary or permanent injunctive relief, except that in the case of temporary or preliminary injunctive relief any party may proceed in court without prior arbitration for the limited purpose of avoiding immediate and irreparable harm.

14.11 Complete Agreement.  This Agreement, including the exhibits hereto, constitutes the entire agreement between the parties.  It supersedes and replaces all prior or contemporaneous understandings or agreements, written or oral, regarding such subject matter, and prevails over any conflicting terms or conditions contained on printed forms submitted with purchase orders, sales acknowledgments or quotations.  This Agreement may not be modified or waived, in whole or part, except in a writing signed by an officer or duly authorized representative of both parties.

14.12 Severability.  In the event that any provision of this Agreement is found to be unenforceable, such provision will be reformed only to the extent necessary to make it enforceable, and the remainder will continue in effect, to the extent consistent with the intent of the parties as of the Effective Date.

14.13 No Waiver.  The failure of either party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other party.

14.14 Assignment.  This Agreement may not be assigned by LICENSEE without the prior written consent of AVANT, which consent shall be granted or denied in AVANT’s sole discretion.  Notwithstanding the foregoing to the contrary, LICENSEE may assign this Agreement without the written consent of AVANT to (a) a corporation or other business entity succeeding to all or substantially all the assets and business of LICENSEE by merger or purchase or (b) a corporation or other business entity acquiring directly or indirectly all of the issued and outstanding share capital of LICENSEE, provided in

11
