Nothing contained in this Section 5.2.2 is intended to limit the rights of either party to seek or any court to enter any lawful form of equitable relief or any available provision of such relief ordered by the court, other than termination of this Agreement. 5.3 Termination. This Agreement shall terminate immediately upon the ----------- transfer of any or all of the assets of the COMPANY to Compagnie Saint Gobain or any Affiliate thereof, or upon the COMPANY becoming an Affiliate of Compagnie Saint Gobain. Immediately upon termination of this Agreement, COMPANY shall cease using the OC Software and return all copies of the OC Software to OC or destroy them. Within thirty (30) days from the date of termination, COMPANY shall provide OC with a written statement certifying that all copies of the OC Software have been returned to OC or destroyed. 6. OWNERSHIP RIGHTS ---------------- Any reference to sale or purchase notwithstanding, title to the OC Software and all copies thereof shall be and remain in OC, and no title to or ownership of the OC Software or any portion thereof is conveyed or transferred to COMPANY. COMPANY acknowledges that the OC Software contains confidential and proprietary information and trade secrets of OC whether or not the OC Software, or any portion thereof, is or may be copyrighted or copyrightable and/or 6 patented or patentable, and that disclosure of the OC Software to COMPANY is on the basis of the confidential relationship between COMPANY and OC under this Agreement. 7. CONFIDENTIALITY --------------- COMPANY acknowledges that the OC Software is supplied in the strictest confidence and contains valuable trade secrets of OC. COMPANY hereby agrees to maintain the OC Software in confidence using the same degree of care as COMPANY takes to safeguard its own proprietary information and trade secrets of the same general nature, but in no event shall COMPANY use less than a reasonable degree of care, and to refrain from publishing or disclosing the OC Software to others (except as expressly provided in Section 2.1 above). COMPANY shall disclose the confidential information contained in the OC Software only to those employees and agents of COMPANY that have a reasonable need to use the OC Software in connection with the purposes of this Agreement.

PROPRIETARY NOTICES ------------------- COMPANY shall not remove, alter or modify any proprietary rights notice(s) included on or associated with the OC Software. 7 9. OC'S REPRESENTATIONS AND WARRANTIES. ----------------------------------- 9.1 OC represents and warrants that it has the necessary authority and title to grant the license in Section 2 and to enter into and perform its obligations under this Agreement and it has not acted in any way that would interfere with COMPANY's rights as granted herein except as otherwise disclosed herein or in the SPA. 9.2 COMPANY ACKNOWLEDGES THAT OC DELIVERS THE OC SOFTWARE "AS IS."
