ACCORDINGLY, BUYER AND SELLER AGREE THAT, IN SUCH CIRCUMSTANCES, IT WOULD BE REASONABLE TO AWARD SELLER, AS SELLER’S SOLE AND EXCLUSIVE REMEDY AT LAW OR IN EQUITY (EXCEPT AS OTHERWISE PROVIDED BELOW), “LIQUIDATED DAMAGES” EQUAL TO THE DEPOSIT (EXCLUSIVE OF ANY INTEREST ACCRUED THEREON). THEREFORE, IF (X) SELLER FULLY PERFORMS ITS OBLIGATIONS UNDER THIS AGREEMENT, (Y) BUYER DOES NOT ELECT TO TERMINATE THIS AGREEMENT IN ACCORDANCE WITH PARAGRAPH 5.3, PARAGRAPH 11.3.1, OR PARAGRAPH 22, AND (Z) THE TRANSACTION CONTEMPLATED IN THIS AGREEMENT DOES NOT CLOSE AS A RESULT OF A BREACH BY BUYER OF BUYER’S OBLIGATIONS UNDER THIS AGREEMENT, THEN SELLER MAY INSTRUCT ESCROW HOLDER TO CANCEL THE ESCROW, WHEREUPON ESCROW HOLDER SHALL IMMEDIATELY PAY SELLER THE DEPOSIT (EXCLUSIVE OF ANY INTEREST ACCRUED THEREON) AND IMMEDIATELY THEREAFTER SHALL CANCEL THE ESCROW, AND SELLER SHALL BE RELIEVED FROM ALL OBLIGATIONS AND LIABILITIES UNDER THIS AGREEMENT, EXCEPT FOR ANY SURVIVING OBLIGATIONS. THE PAYMENT OF THE DEPOSIT (EXCLUSIVE OF ANY INTEREST ACCRUED THEREON) AS LIQUIDATED DAMAGES IS NOT INTENDED AS A FORFEITURE OR PENALTY WITHIN THE MEANING OF CALIFORNIA CIVIL CODE SECTIONS 3275 OR 3369, BUT IS INTENDED TO CONSTITUTE LIQUIDATED DAMAGES TO SELLER PURSUANT TO CALIFORNIA CIVIL CODE SECTIONS 1671, 1676, AND 1677.

ANY TERMINATION OF THIS AGREEMENT BEFORE THE CLOSE OF ESCROW, INCLUDING, WITHOUT LIMITATION, BUYER’S INDEMNIFICATION OBLIGATIONS UNDER PARAGRAPH 9 OF EACH APPLICABLE INSPECTION AGREEMENT, OR (B) SELLER’S RIGHTS TO OBTAIN FROM BUYER ALL COSTS AND EXPENSES OF ENFORCING THE LIQUIDATED DAMAGE PROVISION CONTAINED IN PARAGRAPH 20.1 ABOVE, INCLUDING “LEGAL COSTS” PURSUANT TO PARAGRAPH 26 BELOW.

20.2.2 THE PARTIES AGREE THAT SELLER WOULD SUFFER MATERIAL INJURY OR DAMAGE NOT COMPENSABLE BY THE PAYMENT OF MONEY IF BUYER WERE TO BREACH OR VIOLATE THE CONFIDENTIALITY OBLIGATIONS UNDER THE CNDA, PARAGRAPH 11 OF EACH APPLICABLE INSPECTION AGREEMENT, OR PARAGRAPH 27 BELOW. ACCORDINGLY, NOTWITHSTANDING THE PROVISIONS OF PARAGRAPH 20.1 ABOVE, IN ADDITION TO ALL OTHER REMEDIES THAT SELLER MAY HAVE, SELLER MAY BRING AN ACTION IN EQUITY OR OTHERWISE FOR SPECIFIC PERFORMANCE TO ENFORCE COMPLIANCE WITH THE CNDA, PARAGRAPH 11 OF ANY APPLICABLE INSPECTION AGREEMENT, OR PARAGRAPH 27 BELOW, OR AN INJUNCTION TO ENJOIN THE CONTINUANCE OF ANY SUCH BREACH OR VIOLATION THEREOF.

20.3 ACKNOWLEDGMENT. SELLER AND BUYER ACKNOWLEDGE THAT THEY HAVE READ AND UNDERSTAND THE PROVISIONS OF THIS PARAGRAPH 20 AND BY THEIR INITIALS IMMEDIATELY BELOW AGREE TO BE BOUND BY ITS TERMS.

21. BUYER’S REMEDIES. IF SELLER FAILS TO CONVEY THE PROPERTY TO BUYER IN ACCORDANCE WITH THE PROVISIONS OF THIS AGREEMENT, AND SUCH FAILURE CONSTITUTES A DEFAULT BY SELLER UNDER THIS AGREEMENT, THEN BUYER SHALL BE ENTITLED TO SEEK ALL REMEDIES AVAILABLE TO BUYER, AT LAW OR IN EQUITY, INCLUDING AN ACTION FOR EQUITABLE RELIEF. SELLER HEREBY AGREES THAT THE PROPERTY IS UNIQUE AND THAT IF SELLER FAILS TO CONVEY THE PROPERTY TO BUYER IN ACCORDANCE WITH THE PROVISIONS OF THIS AGREEMENT, AND SUCH FAILURE CONSTITUTES A DEFAULT BY SELLER UNDER THIS AGREEMENT, SUCH FAILURE COULD CAUSE IRREPARABLE HARM TO BUYER. ACCORDINGLY, SELLER AGREES THAT EQUITABLE RELIEF IS A PROPER AND FAIR REMEDY FOR SUCH FAILURE. SELLER AND BUYER ACKNOWLEDGE THAT THEY HAVE READ AND UNDERSTAND THE PROVISIONS OF THIS PARAGRAPH 21 AND BY THEIR INITIALS IMMEDIATELY BELOW AGREE TO BE BOUND BY ITS TERMS.

Each Party’s obligations set forth in this Paragraph shall survive the termination of this Agreement and Escrow before the Close of Escrow.

26. Legal Costs. Should either Party institute any action or proceeding against the other Party, by reason of or alleging the failure of the other Party to comply with any or all of its obligations under this Agreement, whether for declaratory or other relief, then the Party that prevails in such action or proceeding shall be entitled, in addition to any other recovery or relief, to its reasonable attorneys’ fees and expenses and consultant and expert fees and expenses related thereto (whether at the administrative, trial, or appellate levels) (“Legal Costs”). Any judgment, order, or award entered in such action or proceeding shall contain a specific provision providing for the recovery of attorneys’ fees and costs and consultant and expert fees and expenses incurred in enforcing, perfecting, and executing such judgment. A Party shall be deemed to have prevailed in any such action or proceeding (without limiting the generality of the foregoing) if such action or proceeding is dismissed upon the payment by the other Party of the sums allegedly due or the performance of obligations allegedly not complied with, or if such Party obtains substantially the relief sought by it in the action or proceeding, irrespective of whether such action or proceeding is prosecuted to judgment. As used in this Agreement, the term “Legal Costs” shall include, without limitation, attorneys’ and experts’ fees, costs, and expenses incurred in the following: (a) post judgment motions and appeals; (b) contempt proceedings; (c) garnishment, levy, and debtor and third party examinations; (d) discovery; and (e) bankruptcy litigation.
