DEFAULT

Section 8.1                                   To PRIII Member’s Obligations.  If, on the Closing Date, (i) ESS is in default of any of its material obligations hereunder, or (ii) to the actual knowledge of PRIII Member, any of ESS’s representations or warranties are, in the aggregate, untrue, inaccurate or incorrect, in any material respect, or (iii) the Closing otherwise fails to occur by reason of ESS’s failure or refusal to perform its material obligations hereunder in a prompt and timely manner, and any such circumstance described in any of clauses (i), (ii) or (iii) continues for five (5) Business Days after written notice from PRIII Member to ESS, which written notice shall detail such default, untruth or failure, as applicable, then PRIII Member may, as its sole and exclusive remedy, elect to (a) terminate this Agreement by written notice to ESS, promptly after which the Deposit shall be paid to PRIII Member as liquidated damages and, thereafter, the parties shall have no further rights or obligations hereunder except for obligations which expressly survive the termination of this Agreement; or (b) waive the condition and proceed to Closing.  If this Agreement is so terminated, then PRIII Member shall be entitled to the Deposit as liquidated damages, and thereafter neither party to this Agreement shall have any further rights or obligations hereunder.  THE AMOUNT PAID TO AND RETAINED BY PRIII MEMBER AS LIQUIDATED DAMAGES PURSUANT TO THE FOREGOING PROVISIONS SHALL BE PRIII MEMBER’S SOLE AND EXCLUSIVE REMEDY IF ESS FAILS TO CLOSE THE TRANSACTION.  THE PARTIES HERETO EXPRESSLY AGREE AND ACKNOWLEDGE THAT PRIII MEMBER’S ACTUAL DAMAGES IN THE EVENT OF A DEFAULT BY ESS WOULD BE EXTREMELY DIFFICULT OR IMPRACTICABLE TO ASCERTAIN AND THAT THE AMOUNT OF THE DEPOSIT THEREON REPRESENTS THE PARTIES’ REASONABLE ESTIMATE OF SUCH DAMAGES.

14

survive the termination of this Agreement, or (b) waive the condition and proceed to close the Transaction, or (c) seek specific performance of this Agreement by PRIII Member.  As a condition precedent to ESS exercising any right it may have to bring an action for specific performance hereunder, ESS must commence such an action within sixty (60) days following the occurrence of PRIII Member’s default.  ESS agrees that its failure to timely commence such an action for specific performance within such sixty (60) day period shall be deemed a waiver by it of its right to commence an action for specific performance as well as a waiver by it of any right it may have to file or record a notice of lis pendens or notice of pendency of action or similar notice against all or any portion of the Properties.  PRIII MEMBER ACKNOWLEDGES THAT THE INTERESTS REPRESENT INDIRECT INTERESTS IN REAL PROPERTY AND, AS SUCH, ARE UNIQUE, THAT AN ACTION FOR DAMAGES FOR PRIII MEMBER’S BREACH OF ITS MATERIAL OBLIGATIONS UNDER THIS AGREEMENT AT THE TIME OF OR PRIOR TO CLOSING WILL NOT ADEQUATELY COMPENSATE ESS FOR THE LOSS OF THE INTERESTS AND THAT AS A RESULT ESS WILL ONLY BE MADE WHOLE FOR SUCH A MATERIAL BREACH BY PRIII MEMBER IF ESS IS ENTITLED TO BRING AN ACTION FOR SPECIFIC PERFORMANCE OF PRIII MEMBER’S DUTIES UNDER THIS AGREEMENT.  For the purposes of this Section 8.2 only, “actual knowledge” of ESS as used in this Section 8.2 shall refer only to the actual knowledge of Charley Allen, Tim Arthurs, Scott Stubbs, Mackay Reid, David Rassmussen or Steven Tyler.

CERTIFICATE OF NON-FOREIGN STATUS

BY ENTITY TRANSFEROR

Section 1445 of the Internal Revenue Code provides that a transferee of a United States real property interest must withhold tax if the transferor is a foreign person.  For U.S. tax purposes (including Section 1445), the owner of a disregarded entity (which has legal title to a U.S. real property interest under local law) will be the transferor of the property and not the disregarded entity.  PRISA III CO-INVESTMENT, LLC, a Delaware limited liability company (“Seller”), will transfer its membership interests in ESS PRISA III LLC which owns the properties listed on Exhibit A attached hereto (the “Properties”) to ESS Extra Space Sixty Three, LLC, a Delaware limited liability company (“Transferee”).  Seller is a disregarded entity that is wholly-owned by PRISA III REIT Operating LP, a Delaware limited partnership (“Transferor”).

1.                                      In order to inform Transferee that withholding of tax is not required upon disposition of a U.S. real property interest by Transferor, the undersigned hereby certifies and declares by means of this certificate the following on behalf of the Transferor.

(a)                                 The Transferor is not a foreign corporation, foreign partnership, foreign trust or foreign estate (as these terms are defined in the Internal Revenue Code and Income Tax Regulations).

(b)                                 The Transferor is not a disregarded entity as defined in § 1.1445-2(b)(2)(iii) of the Code.

(c)                                  The Transferor’s employer identification number is:                            .

(d)                                 The Transferor’s office address is:                                                         .

2.                                      The Transferor understands that this certificate may be disclosed to the Internal Revenue Service by the Transferee and that any false statement contained in this certificate may be punished by fine, imprisonment, or both.
