No failure or delay (whether by course of conduct or otherwise) by Bionova or Savia in exercising any right, power or remedy which either may have under any of the Transaction Documents shall operate as a waiver thereof or of any other right, power or remedy, nor shall any single or partial exercise by Bionova or Savia of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No waiver of any provision of any Transaction Document and no consent to any departure therefrom shall ever be effective unless it is in writing and signed by the parties hereto, and then such waiver or consent shall be effective only in the specific instances and for the purposes for which given and to the extent specified in such writing.

THIS WRITTEN AGREEMENT AND THE OTHER TRANSACTION DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES HERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES HERETO.

9.4 Governing Law; Submission to Process. EXCEPT TO THE EXTENT THAT THE LAW OF ANOTHER JURISDICTION IS EXPRESSLY ELECTED IN A TRANSACTION DOCUMENT, THIS AGREEMENT AND THE OTHER TRANSACTION DOCUMENTS, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

EACH OF BIONOVA AND SAVIA IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

9.5 Waiver of Jury Trial, Punitive Damages, Etc. EACH OF BIONOVA AND SAVIA HEREBY:

(a) KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH THE TRANSACTION DOCUMENTS OR THE PURCHASE AND SALE OF ANY NEW COMMON STOCK CONTEMPLATED THEREBY OR ASSOCIATED THEREWITH;

(b) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES;

(c) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS; AND

(d) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE OTHER TRANSACTION DOCUMENTS AND THE TRANSACTIONS

9.10 Specific Performance. Bionova recognizes that money damages may be inadequate to compensate Savia for a breach by Bionova of its obligations hereunder, and Bionova irrevocably agrees that Savia shall be entitled to the remedy of specific performance or the granting of such other equitable remedies as may be awarded by a court of competent jurisdiction in order to afford Savia the benefits of this Agreement and that Bionova shall not object and hereby waives any right to object to such remedy or such granting of other equitable remedies on the grounds that money damages will be sufficient to compensate Savia.
