If PcoMed makes such election, the Right shall be a nonexclusive right at the end of such 45-day cure period, and PcoMed may thereafter allow other Third Parties to use the PcoMed Surface Modification Technology in products that are in competition with the Integra Products. 3.3. Exclusive Coating. Integra (i) shall not apply or have applied any other coating to any Integra Products treated with the PcoMed Surface Modification Technology, unless that coating is for the sole purpose of identification or sterilization and (ii) shall not process the PcoMed Surface Modification Technology in any way that will adversely affect its integrity or performance. 7 *** Portions of this page have been omitted pursuant to a request for Confidential Treatment filed separately with the Commission. 4.

In the event that a party materially defaults under or materially breaches any of the provisions of this Agreement, the other party shall have the right to terminate this Agreement upon 60 days' prior written notice, unless such material default or breach is cured during such 60-day period (or in the event any breach is incapable of being cured in such time period, the other party presents a plan to attempt cure of such breach and prevent similar breaches, which plan is reasonably acceptable to the terminating party), in which event this Agreement shall continue in full force and effect. (b) Bankruptcy. If a party institutes for its protection or is made a defendant in any proceeding under bankruptcy, insolvency, reorganization or receivership law, or such party is placed in receivership, makes an assignment for benefit of creditors or is unable to meet its debts in the regular course of business, the other party may elect to terminate this Agreement immediately by written notice to the first party without prejudice to any right or remedy the other party may have, including damages for breach. 4.4.
