TECHNOLOGY PROPERTIES LIMITED INC.

and

CHARLES H. MOORE

Dated as of June 7, 2005

11.9 Severability. The failure of any provision of this Agreement by virtue of its being construed as invalid or otherwise unenforceable shall render the entire Agreement cancelable at the option of the party asserting the enforceability of the said provision. Notwithstanding the foregoing, the parties expressly agree that the Stipulated Final Judgment, Section 11.2(a), Section 11.13 and Section 11.14 are severable and have significance independent of this Agreement and any other agreements and transactions contemplated hereby and thereby, and as such shall not be affected or disturbed by the invalidity, illegality or unenforceability of any such provision or provisions or of the entirety of any such agreements.

11.10 Construction. The parties hereto intend that each representation, warranty and covenant contained herein shall have independent significance. If any party has beached any representation, warranty or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) that the party has not breached shall not detract from or mitigate the fact that the party is in breach of the first representation, warranty or covenant.

11.11 Cumulative Remedies. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

11.12 Specific Performance. The parties hereby acknowledge and agree that the failure of any party to perform its agreements and covenants hereunder, including its failure to take all actions as are necessary on its part to consummate the agreements contemplated hereby, will cause irreparable injury to the other party, for which damages, even if available, will not be an adequate remedy. Accordingly, each party hereby consents to the issuance of injunctive relief without bond by any court of competent jurisdiction to compel performance of such party's obligations and to the granting by any court of the remedy of specific performance of its obligations hereunder.

ARTICLE V
TERM

5.1 This Commercialization Agreement shall continue for the useful life of the MSD Patents, which shall be deemed to be the greater of the period of time during which any of the MSD Patents is either (i) susceptible to legal protection, or (ii) reasonably perceived to have commercial value.

5.2 In the event that facts or events are discovered or occur which materially reduce TPL's evaluation of the useful life or commercial value of the MSD Patents, or the viability of the Project, TPL may reduce the term of this Commercialization Agreement accordingly by providing P-Newco with ninety (90) days written notice, provided that TPL shall not reduce the term of this Commercialization Agreement to less than six (6) months.

5.3 After the expiration of the term provided for above, neither party shall have any further obligation hereunder other than the administration of all outstanding transactions as under Article VI below, and the obligations of confidentiality undertaken by the parties.
