	If Metabolix shall elect not to file, prosecute, or maintain any METABOLIX PATENT RIGHT or INTEGRATED P4HB STRAIN PATENT RIGHT in any country, including omitting to list any countries at the time of election of countries in a PCT or other supranational filing, Metabolix shall so notify Tepha in writing at least thirty (30) days prior to any election, filing, action, payment or the like being due or any other action or inaction in that country or election that would result in loss of patent rights, abandonment, disclaimer, cancellation, admission of invalidity or unenforceability, or withdrawal of any claim of such METABOLIX PATENT RIGHT or INTEGRATED P4HB STRAIN PATENT RIGHT, in which event Tepha shall have the right, but not the obligation, to (a) elect, file, prosecute, or maintain such METABOLIX PATENT RIGHT or INTEGRATED P4HB STRAIN PATENT RIGHT in such country, or (b) require Metabolix, prior to any loss of rights, to assign such METABOLIX PATENT RIGHT or INTEGRATED P4HB STRAIN PATENT RIGHT in such country to Tepha (which patent right will then be deemed automatically added to Appendix 1 of the Fourth Amendment and included within the definition of ASSIGNED METABOLIX PATENT RIGHTS).

After assignment of any METABOLIX PATENT RIGHTS or INTEGRATED P4HB STRAIN PATENT RIGHTS to TEPHA under this Section 6.4, TEPHA, its affiliates, successors and/or assigns shall not make any claim or institute any legal action asserting the METABOLIX PATENT RIGHTS or INTEGRATED P4HB STRAIN PATENT RIGHTS against METABOLIX or its affiliates, sublicensees, partners, customers, end users, vendors, sub-contractors, successors and/or assigns in connection with the practice outside the FIELD OF USE of such METABOLIX PATENT RIGHTS or INTEGRATED P4HB STRAIN PATENT RIGHTS.
