Each party shall obtain the execution of proprietary nondisclosure agreements with its subsidiaries, employees, agents and consultants having access to Confidential Information of the other party, and shall exercise due care in administering such agreements. 8.5 Rights Under Breach. Each party acknowledges that the other party's Confidential Information is an extremely valuable business asset, the misuse or improper disclosure of which would cause irreparable harm to the interest of such party.

If any Section, provision, or clause thereof in this Agreement shall be, found or be held to be invalid or unenforceable in any jurisdiction in which this Agreement is being performed, the remainder of this Agreement shall be valid and enforceable and the parties shall negotiate, in good faith, a substitute, valid and enforceable provision which most nearly effects the parties' intent in entering into this Agreement. 10.5 Disclosure. Neither IPM nor Censtor will voluntarily disclose to any person, firm or corporation the contents of this Agreement unless under a protective order, or ordered by a court of law, or as otherwise required by the SEC, or under a confidential disclosure agreement; provided, however, that IPM is authorized to issue public statements related to its authority to act as Censtor's exclusive representative hereunder. 10.6 Settlement of Disputes; Choice of Law.

The relationship of Censtor and IPM established by this Agreement is that of independent contractors. Nothing contained herein or done in pursuance of this Agreement shall be construed to give either party the power to direct and control the day-to-day activities of the other, or constitute either party the agent of the other party for any purpose or in any sense whatsoever, or constitute the parties as partners or joint venturers. 10.11 Modification. No alteration, amendment, waiver, cancellation or any other in any term or condition of this Agreement shall be valid or binding on either party unless same shall have been mutually assented to in writing by both parties. 10.12 Waiver. The failure of either party to enforce at any time the provisions of this Agreement, or the failure to require at any time performance by the other party of any of the provisions of this Agreement, shall in no way be constituted to be a present or future waiver of such provisions, nor in any way affect the validity of either party to enforce each and every provision thereafter. The express waiver by either party of any provision, condition or requirement of this Agreement shall not constitute a waiver of any future obligation to comply with such provision, condition or requirement. 10.13 Entire Agreement. The terms and conditions herein constitute the entire agreement between the parties and supersede all previous agreements and understandings, whether oral or written, between the parties hereto with respect to the subject matter hereof and no agreement or understanding varying or extending the same shall be binding upon either party hereto unless in a written document signed by the party to be bound thereby. 10.14 Section Headings and Language.
