As a condition precedent to Company's obligations hereunder, the representations and warranties contained in this Section 5.1 shall be true and correct on the Closing Date.

Remedies of Default Section 9.1 In the event of Contributor's default hereunder, Company may elect, at its option, as its sole and exclusive remedies, either to (a) terminate this Agreement; or (b) if Contributor's default arises out of its alleged failure to perform its obligation to convey title on the Closing Date, enforce specific performance hereunder against Contributor. Section 9.2 In the event that Contributor is unable to consummate the sale contemplated hereby due to a default by Company, then, as Contributor's sole and exclusive remedy and relief, Contributor shall be entitled to the Cash Payment as liquidated damages for Company's default. Such amount is agreed upon by and between the Contributor and the Company as liquidated damages, due to the difficulty and inconvenience of ascertaining and measuring actual damages, and the uncertainty thereof; and no other damages, rights or remedies shall in any case be collectible, enforceable or available to the Contributor other than as specified in this Article 9, but the Contributor shall accept said Cash Payment as the Contributor's total damages and relief. If Company fails to timely deliver the Cash Payment, Contributor shall have all rights at law or equity against Company for its default. Section 9.3 Notwithstanding the provisions of Sections 9.1 and 9.2 above, in the event that after Closing a party (the "Defaulting Party") breaches an obligation hereunder which is expressly stated herein to survive Closing, the Defaulting Party shall be liable to the other party (the "Non-Defaulting Party") for the damages incurred by the Non- Defaulting Party as a result of such breach. Section 9.4 Contributor and Company specifically acknowledge and agree that any limitation on remedies set forth in this Article 9 does not apply to the express hold harmless and indemnification agreements set forth in this Agreement or to the amounts recoverable pursuant to Section 10.5 hereof.
