Buyer shall have the “Title Inspection Period” (as hereafter defined) to object in writing to any matter shown in the Preliminary Title Report. If Buyer fails to object to any matter set forth on the Preliminary Title Report within such time period, the condition of title to the Property shall be deemed approved by Buyer. If Buyer does object in writing to any matter disclosed in the Preliminary Title Report, Buyer shall specify the matter objected to with detail (the “Title Objection Notice”). Seller shall have five (5) days after receipt of a Title Objection Notice to attempt to remove the matter objected to by Buyer; it being understood that Seller is under no obligation to remove any matter objected to by Buyer. If Seller is unable or unwilling to remove the matter set forth in the Title Objection Notice, Buyer shall elect in writing within five (5) days after the expiration of such five (5) day period, to either: (i) cancel this Agreement and receive a return of all ▇▇▇▇▇▇▇ Money paid; or (ii) close escrow without any reduction in the Purchase Price, canceling and waiving the Title Objection Notice and taking title subject to such matters. Failure to give notice to Seller of Buyer’s election shall constitute an election to cancel this Agreement.

The Survey shall comply with the certification standards attached hereto as Exhibit “F”. Buyer shall have until the end of the Title Inspection Period to object in writing to any matter shown in the Survey. If Buyer fails to object within such time period, the legal description of the Property and any other matters shown in the Survey shall be deemed approved by Buyer.

(c) Title Inspection Period. As used herein the phrase “Title Inspection Period” shall mean that period of time commencing on the Effective Date and, provided Seller timely provided the Title Report and Survey as provided in Sections 5(a) and 5(b) above, ending on the date which is thirty (30) days thereafter; provided, however, the Title Inspection Period shall be extended on a day for day basis if the Title Report is not timely delivered as provided in Sections 5(a) above. If Escrow Agent issues an amended Title Report after the Title Inspection Period, or if the surveyor issues an amended Survey after the Title Inspection Period, and either shows new title exceptions (“New Exceptions”), Buyer shall have an additional five (5) business days from receipt of such amendment(s) to review and approve or disapprove the New Exceptions only.

Title to the Property shall be conveyed subject only to those liens, easements, rights of way and other encumbrances as may be approved or deemed approved by Buyer as provided in paragraph 5(a) and 5(b) above (the “Permitted Exceptions”). Seller shall not place, permit, or cause to be placed any liens or encumbrances on the title to the Property from the date of the Preliminary Title Report referenced above through Closing or thereafter. If Seller places, permits, or causes a lien or encumbrance on the Property, contrary to the provisions of this Agreement, which can be removed by the payment of money, Escrow Agent is hereby expressly authorized, directed, and instructed to pay such monies in order to remove the lien or encumbrance at Closing from monies otherwise payable to Seller at Closing and the net proceeds otherwise available to Seller at Closing shall be reduced accordingly. To the extent that monies available to Seller at Closing are insufficient to cause any such lien or encumbrance to be removed, Seller shall, on or before the date set for Closing, cause additional monies to be deposited with Escrow Agent to enable Escrow Agent to remove the lien or encumbrance.

(d) Property Documents. Seller shall, within five (5) days after the Effective Date, deliver to Buyer true and correct copies of documents set forth on Exhibit “G” (the “Property Documents”).

Seller shall cause access to the Property to be available to Buyer and the persons so designated by it and shall afford them the opportunity to inspect and perform any tests upon the Property that Buyer deems necessary or appropriate to determine whether the Property is suitable for Buyer’s purposes. If Buyer, after conducting such inspections, investigations, and tests, determines that the Property or any part thereof or the Property Documents, are not in Buyer’s sole discretion satisfactory for any reason, then Buyer may elect, at any time on or prior to the end of the Property Inspection Period, to cancel this Agreement by written notice to Seller and Escrow Agent. Notwithstanding anything else contained herein to the contrary, if Buyer has not provided Seller with a written notice of approval of the Property or Property Documents prior to the end of the Property Inspection Period, the Property and Property Documents shall be deemed disapproved by Buyer and Seller’s shall be deemed to have elected to cancel this Agreement and receive a return of all ▇▇▇▇▇▇▇ Money paid.

Buyer shall indemnify and hold Seller harmless for, from and against any and all losses, defaults, liabilities, causes of action, demands, claims, damage or expenses of every kind including, without limitation, reasonable attorneys’ fees and court costs, arising as a result of each of Buyer’s inspections (“Inspection Indemnity”). The Inspection Indemnity shall survive the Close of Escrow or any termination or cancellation of this Agreement, and shall not be subject to or limited by, the provisions of Section 11 hereof.

Upon such event, this Agreement shall be deemed null and void and neither party shall have any further rights or obligations to the other hereunder or on account hereof, except for those which by the provisions of this Agreement are expressly stated to survive or occur at termination of this Agreement. If Buyer does not elect to cancel this Agreement as provided in this Section 5, Buyer shall be deemed to have approved all matters concerning the Property.

(g) Satisfaction with Property. Notwithstanding anything herein to the contrary, Buyers obligation to purchase the Property shall be conditioned upon Buyer’s determination, prior to the end of the of the Title Inspection Period, that the condition of the Property (including, without limitation, environmental matters) and the feasibility of this transaction are acceptable to Buyer in its sole and absolute discretion. If Buyer has not provided Seller with a written notice of approval of the Property prior to the end of the Title Inspection Period as provided in this Section 5, Buyer shall be deemed to have elected to cancel this Agreement and receive a return of all ▇▇▇▇▇▇▇ Money paid. Upon any such termination the provision of Section 5(f) shall control.

(h) Property Sold “As Is, Where is”. Buyer is purchasing the Property “As IS, Where Is, with no representations and warranties except as set forth herein.

The cost of the standard coverage portion of the Title Policy shall be paid by Seller. Buyer shall pay any additional premium for an extended owner’s policy, any lender’s policy requested by Buyer and any endorsements requested by Buyer.

7. Prorations and Payments in Escrow Account. Subject to the provisions of this Agreement, all rentals, revenues, and other income, if any, from the Property, and taxes and other regular expenses, if any, affecting the Property shall be paid or shall be prorated as of midnight on the day preceding the Closing in accordance with the provisions set forth below. For purposes of calculating prorations, Buyer shall be deemed to be in title to the Property, and therefore entitled to the income and responsible for the expenses, for the entire day upon which the Closing occurs. Any apportionments and prorations which are not expressly provided for below shall be made in accordance with local customary practice. Buyer and Seller agree to prepare a schedule

of tentative adjustments prior to the Closing. Such adjustments, if and to the extent known and agreed upon as of the Closing, shall be paid by Buyer to Seller (if the prorations result in a net credit to the Seller) or by Seller to Buyer (if the prorations result in a net credit to the Buyer), by increasing or reducing the cash to be paid by Buyer at the Close of Escrow. Any such adjustments not determined or not agreed upon as of the Closing shall be paid by Buyer to Seller, or by Seller to Buyer as the case may be, in cash as soon as practicable following the Closing, but (except with respect to Taxes) in any event within ninety (90) days after the date of Closing, and the parties obligations with respect to such prorations shall survive Closing. A copy of the schedule of adjustments as agreed upon by Buyer and Seller shall be delivered to Escrow Agent at least one (1) business day prior to the Closing Date.

(a) Rents. Subject to the provisions of this Section 7, Rents shall be prorated as of the Closing. “Rents” as used herein includes fixed monthly rentals, additional rentals, any additional rental consisting of operating cost pass-throughs or other payments payable by tenants to the landlord under the Leases as reimbursement to the landlord for costs incurred by the landlord with respect to the Property, percentage rentals, escalation rentals, retroactive rentals, rent tax, and other sums and charges payable by tenants under the Leases, less any agreed credits due to tenants. Rents are “Delinquent” when they were due prior to the Closing Date, and payment thereof has not been made on or before the Closing Date. Delinquent Rent shall not be prorated at Closing. All Rent collected by Buyer or Seller from each tenant from and after Closing will be applied as follows: (i) first, to any accrued Rents owing to Buyer, and (ii) second to Delinquent Rents owing to Seller for the period prior to Closing. Any Rent collected by Buyer and due Seller will be promptly remitted to Seller. Any Rent collected by Seller and due Buyer shall be promptly remitted to Buyer. Buyer shall use reasonable efforts to collect Delinquent Rents owed to Seller in the ordinary course of its business; provided, however, Seller shall not contact any such tenant with respect to Delinquent Rent and Buyer shall not be required commence or pursue any legal proceedings against any tenant seeking eviction of such tenant or the termination of the underlying Lease.

(b) Prepaid Rentals. Rentals already received by Seller attributable to periods after the Closing and the amount of any other credits due tenants shall be paid to Buyer at the Closing, or credited to Buyer against the Purchase Price.

(c) Taxes and Assessments. All non-delinquent real estate taxes on the Property shall be prorated based on latest available information. At such time as the actual real estate taxes are known, the pro-ration shall be recalculated based on the actual taxes due and if different than the pro-ration done at Closing, the parties shall make an appropriate adjustment. Any amounts due based on such re-proration shall be paid within thirty (30) days. In addition, if, after the Close of Escrow, any supplemental real estate taxes are assessed against the Property by reason of any event occurring prior to the Closing, Buyer and Seller shall re-prorate the real estate taxes following the Close of Escrow. Any delinquent taxes on the Property shall be paid at the Close of Escrow by Seller.

(d) Operating Expenses. All utility service charges for electricity, heat and air conditioning service, other utilities, elevator maintenance, common area maintenance, taxes other than real estate taxes such as rental taxes, other expenses incurred in operating the Property that Seller customarily pays, and any other costs incurred in the ordinary course of business or the management and operation of the Property, shall be prorated on an accrual basis. Seller shall pay all such expenses that accrue prior to the Closing and Buyer shall pay all such expenses accruing on the day of Closing and thereafter. Seller and Buyer shall exercise commercially reasonable efforts to obtain ▇▇▇▇▇▇▇▇ and meter readings as of the Closing to aid in such prorations; provided, however, if despite using such commercially reasonably efforts such ▇▇▇▇▇▇▇▇ or readings are not available at the Closing the parties shall Close based on an estimate and shall re-prorate such amounts when the actual amounts are determined. Any amounts due based on such re-proration shall be paid within thirty (30) days.

(e) Tenant Deposits. At Closing, Buyer shall receive a credit against the Purchase Price in an amount equal to all tenant deposits (and any interest due thereon to tenants) being held by Seller or any other person under the Leases.

(f) Capital Expenditures. All capital and other improvements (including labor and materials) which are performed or contracted for by Seller at or prior to the Closing will be done in a good ▇▇▇▇▇▇▇ like manner and be paid by the Seller, without contribution or proration from Buyer, and the Seller hereby indemnifies, defends and holds Buyer and the Property harmless from any claims respecting same.

(g) Service Contracts. Amounts payable under any Service Contracts which Buyer hereafter elects to assume, if any, shall be prorated on an accrual basis. Seller shall pay all amounts due thereunder which accrue prior to the Close of Escrow and Buyer shall pay all amounts accruing on the Close of Escrow and thereafter. Seller shall pay in full all amounts due under any Service Contracts which Buyer does not elect to assume and Seller indemnifies, defends and holds Buyer harmless from, for and against any claims respecting same.

(h) Employee Compensation. Seller shall pay in full all amounts due under any employment contracts with any employees of Seller performing services on the premises including, without limitation, any payroll, F.I.C.A., accrued vacation and sick pay, contributions to employee-medical or pension funds, any employee benefits, employee-related taxes and any amounts payable under such employment contracts, and Seller indemnifies, defends and holds Buyer harmless from any claims respecting same. Seller and Buyer agree that Buyer is not hiring any of Seller’s employees.

(i) Closing Costs. The Closing costs shall be prorated, adjusted and apportioned between Buyer and Seller as follows:.

(i) The Escrow fee to be paid one-half by Buyer and one-half by Seller;

(ii) The Title Policy premium(s) shall be paid as provided in Section 6 above;

(iii) Seller shall pay the recording fee for the Deed, any required documentary transfer taxes and any documents necessary to clear title to Seller and Buyer shall pay the Affidavit of Value fee or similar filing fees;

(iv) Any other costs shall be prorated between Buyer and Seller per customary real estate practice in Westminster, California; and

(v) Except as expressly set forth herein, each party shall pay its own legal fees in connection with this transaction.

8. Condemnation/Casualty Loss.

(a) Condemnation. If, prior to the Closing, Seller receives notice that all or a Material Portion (as hereinafter defined) of the Property is to be condemned, Seller shall as soon as is reasonably possible give Buyer notice thereof (a “Condemnation Notice”)and Buyer shall have the right to terminate this Agreement upon written notice delivered within ten (10) days after Buyer’s receipt of a Condemnation Notice (which notice must contain the amount of compensation offered for such condemnation). If Buyer so terminates this Agreement then this Agreement shall become null and void, Buyer shall be entitled to a return of the ▇▇▇▇▇▇▇ Money and Seller and Buyer shall have no further rights or obligations hereunder, except as otherwise provided herein; provided, however, that if Buyer elects not to terminate this Agreement the purchase contemplated herein shall be consummated, without reduction of the Purchase Price, within the later of five (5)

days after the expiration of such ten (10) day period or on the Closing, in which event Buyer shall be entitled to all condemnation proceeds applicable to Seller’s interest in the Property. Seller shall assign, transfer and set over to Buyer all of Seller’s right, title and interest in and to such condemnation proceeds necessary to give full effect to this Section. As used herein, a “Material Portion” shall mean five percent (5%) or more of the aggregate gross leasable area of the premises demised under the Leases.

(b) Casualty. In the event of the loss of all or a Material Portion of the Property due to casualty after the date hereof and prior to the Closing Date, the risk of loss shall be on Seller; provided, however, Seller shall as soon as is reasonably possible give notice thereof to Buyer (a “Casualty Notice”) and Buyer may, by written notice given to Seller within ten (10) days following receipt of such Casualty Notice, elect either to (i) cancel and terminate this Agreement and the Escrow and receive the return of the ▇▇▇▇▇▇▇ Money, or (ii) receive, by assignment from Seller, all insurance proceeds, if any, received and/or to be received by Seller as a result of such casualty (in which case the parties shall proceed to consummate the transaction without any resulting adjustment of the Purchase Price). In the event of a casualty loss involving less that a Material Portion of the Property, Buyer’s sole and exclusive remedy shall be as described in clause (ii) above.

9. Closing. Close of Escrow shall take place at the offices of Escrow Agent or where the parties may otherwise mutually agree, ten (10) business days after Buyer waives the last of its contingencies under Section 5 hereof (the “Closing Date”); provided, however, Seller, at Seller’s sole discretion, shall have the right to extend the Closing Date for up to a period of thirty (30) day, by providing Buyer and Escrow Agent prior written notice thereof which such notice must be given at least fifteen (15) days prior to the originally scheduled Closing Date.

10. Default of Buyer or Seller.

(a) Buyer. IF BUYER BREACHES THIS AGREEMENT, SELLER, AS ITS SOLE AND EXCLUSIVE REMEDY, MAY ELECT TO TERMINATE THIS AGREEMENT BY PROVIDING WRITTEN NOTICE THEREOF TO BUYER AND THE ESCROW AGENT. BUYER AND SELLER AGREE THAT BASED UPON THE CIRCUMSTANCES NOW EXISTING, KNOWN AND UNKNOWN, IT WOULD BE IMPACTICAL PR EXTREMELY DIFFICULT TO ESTABLISH SELLER’S DAMAGE BY REASON OF BUYER’S DEFAULT UINDER THIS AGREEMENT. ACCORDIGLY, BUYER AND SELLER AGREE THAT IN THE EVENT OF DEFAULT BY BUYER UNDER THIS AGREEMENT, IT WOULD BE REASONABLE AT SUCH TIME TO AWARD SELLER, AS SELLER’S SOLE AND EXCLUSIVE REMEDY AT LAW “LIQUIDATED DAMAGES” EQUAL TO THE ▇▇▇▇▇▇▇ MONEY AS SELLER’S SOLE REMEDY. AS SUCH, IN THE EVENT BUYER BREACHES THIS AGREEMENT, SELLER SHALL RETAIN THE ▇▇▇▇▇▇▇ MONEY AS LIQUIDATED DAMAGES.

(b) Buyer has full power to carry out the transactions provided for in this Agreement. The execution and delivery of this Agreement by Buyer and the consummation by Buyer of the transactions contemplated herein have been duly and validly authorized by all necessary actions on Buyer’s part, and this Agreement constitutes a valid and legally binding obligation of Buyer, enforceable against Buyer in accordance with its terms subject to the effect of liquidation, rehabilitation, conservatorship, bankruptcy, insolvency, moratorium, reorganization, rearrangement, fraudulent transfer, receivership or similar laws or judicial decisions relating to or affecting the rights of creditors generally;

(c) Neither the execution and delivery of this Agreement, nor the consummation by Buyer of the transactions contemplated hereby, nor the compliance by Buyer with any of the provisions hereof will (i) conflict with or result in a breach of or default under any of the terms, conditions or provisions of any note, bond, mortgage indenture, license, agreement or other instrument or obligation to which Buyer is a party or by which it or any of its properties or assets may be bound, or (ii) violate any order, injunction, decree, statute, rule or regulation applicable to Buyer or any of its assets or properties;

Except as provided herein, each party represents and warrants that it has not in any way obligated the other to pay any broker, finder or any other person or agent any commission or finder’s fee in connection with the execution of this Agreement, or the consummation of the transactions contemplated hereby. Each party agrees to indemnify and hold the other party harmless for, from and against all loss or damage including, without limitation, reasonable attorneys’ fees, arising out of the breach of such representation and warranty by the indemnifying party, which indemnity shall survive termination of this Agreement.

If this Agreement is canceled because one or more of the foregoing conditions are not met then the ▇▇▇▇▇▇▇ Money shall be returned to Buyer and, except as otherwise provided herein, neither party shall have any further obligations to the other hereunder, except that if this Agreement is canceled because of Seller’s breach hereof, the provisions of Section 10 shall control.

(b) The representations and warranties of Buyer in this Agreement shall be true and correct as of the Closing as if made at the Closing.

If the foregoing conditions have not been satisfied by the date scheduled for the Closing, Seller shall have the option either to waive any unsatisfied condition or to cancel this Agreement. If this Agreement is canceled because one or more of the foregoing conditions is not met, then the ▇▇▇▇▇▇▇ Money shall be paid as herein provided, and, except as otherwise may be provided herein, neither party shall have any further obligations to the other hereunder or under the Escrow Instructions, except that if this Agreement is canceled because of Buyer’s breach hereof, the provisions of Section 10 shall control.

All agreements and instruments to be delivered to Buyer shall have been duly executed and, where appropriate, acknowledged by the parties thereto. The foregoing is intended as a summary of items to be delivered at the Closing and shall not be construed to limit or waive any obligations of Seller under this Agreement.

17. Buyer’s Deliveries at Closing. At the Closing, Buyer shall deliver or cause the Escrow Agent to deliver to Seller the following:

(a) The sums required under Section 2;

(b) The net amounts, if any, credited to Seller from the prorations pursuant to the settlement statement approved by Buyer and Seller;

All agreements and instruments to be delivered to Seller shall have been duly executed and, where appropriate, acknowledged by the parties thereto. The foregoing is intended as a summary of items

to be delivered at the Closing and shall not be construed to limit or waive any obligations of Buyer under this Agreement.

18. Assignment by Buyer. Buyer shall have the right to assign this Agreement, without Seller’s consent, to any affiliated party. Buyer shall not have the right to assign this Agreement to any other person or entity without Seller’s prior written consent, which consent will not be unreasonably withheld. In either event, the assignee shall assume in writing all of Buyer’s obligations hereunder, and Buyer shall not be released from its obligations hereunder.

19. Interpretation. This Agreement shall be interpreted according to its fair meaning and neither for nor against either party hereto regardless of which party caused the same to be drafted. Where appropriate, references to one gender shall be deemed to include any other gender and references to the singular or the plural shall be deemed to include either the singular or the plural. Nothing contained herein shall be deemed to create a partnership or joint venture between Buyer and Seller, it being agreed that their relationship is that of an independent contractor.

20. Time/Extensions. Unless provided to the contrary in any particular provision, all time periods shall refer to calendar days and shall expire at 5:00 p.m., Pacific Standard Time, on the last of such days; provided, however, that if the time for the performance of any obligation expires on a day other than a business day (any day other than a Saturday, Sunday or legal holiday), the time for performance shall be extended to the next succeeding day which is a business day. Time is of the essence of this Agreement. Any extension of time granted for the performance of any obligation under this Agreement shall not be considered an extension of time for the performance of any other obligation.

21. Severability. If any provision (or portion thereof) of this Agreement, or its application to any party, is declared invalid, illegal, void or unenforceable in any respect, such provision (or portion thereof) shall be deemed severed from this Agreement and shall be replaced by a provision which the court determines to be substantially equivalent to that stricken, but modified to the extent necessary to cure such invalidity, illegality or unenforceability, in order to give effect to the overall underlying intent of the parties (as demonstrated by the provisions originally contained herein), and the balance of the Agreement shall otherwise remain in full force and effect and shall not be affected thereby.

22. Exhibits and Recitals. Each exhibit attached to this Agreement and each recital is incorporated and made a part of this Agreement by this reference.

All notices, demands, approvals, instructions or other communications (“Notices”) required or permitted hereunder shall be in writing and be given by personal delivery, facsimile transmission (followed by mailing), recognized overnight courier or mail, and shall be deemed given and effectively served upon delivery, or if mailed, upon mailing provided it is thereafter actually delivered (or refused) and is mailed (postage prepaid) by certified or registered mail, return receipt requested, to the address of such party set forth herein, or to such other address as shall have previously been specified in writing by such party to all parties hereto; provided, however, a notice of change of address for Notices shall not be deemed made until actually received. Refusal to accept delivery or to sign a receipt, or the inability to deliver because of a changed address of which no notice previously was given, shall constitute actual receipt. Whenever a party has the right or is required to do some act or give some Notice within a prescribed period after the service of a Notice upon that party and the Notice is served by mail only, three days shall be added to the prescribed period for response. Copies of all Notices given to Buyer or Seller shall be delivered, faxed or mailed, in the manner set forth above, to Escrow Agent as well as the other party, and copies of all Notices given to Escrow Agent shall be delivered, faxed or mailed, in the manner set forth above, to the other party.

than three (3) addresses. A copy of all Notices shall be sent as follows:

This Agreement and any document(s) executed contemporaneously herewith, contain the complete agreement between the parties hereto with respect to the subject matter hereof, and all prior representations, promises and understandings (whether written or oral, express or implied) and letters of intent, if ever they existed, have been superseded by such instruments or have been merged therein. No provision of this Agreement may be amended, deleted or supplemented except by a written instrument dated and executed by both Buyer and Seller.

25. Representation/Attorneys’ Fees. Each of the parties acknowledges that such party has been, or has had the opportunity to be, represented by an attorney in connection with the preparation, execution and delivery of this Agreement. In the event “legal proceedings” are brought or an attorney is retained by any party to this Agreement to enforce the terms of this Agreement or to collect for the breach hereof or for the interpretation of any provision herein in dispute, or to participate in any bankruptcy or reorganization proceeding involving the other party, the prevailing party shall be entitled to recover, in addition to any other remedy, reimbursement for reasonable attorneys’ fees, expert witness fees and costs, court costs, arbitration costs, costs of investigation and other related expenses incurred in connection therewith. If suit is instituted, attorneys’ fees shall be fixed by the Judge of the Court or Arbitrator. “Legal proceedings” include binding arbitration, lower court action, appeal from a lower court judgment, special action in an appellate court, and any proceeding in state or federal bankruptcy court. The “prevailing party” as used in the context of proceedings: (i) in the bankruptcy court means the prevailing party in an adversary proceeding or contested matter, and all other actions taken by the non-bankruptcy party which are reasonably necessary to protect its rights under this Agreement; and, (ii) in any court other than a bankruptcy court means the party that prevails in obtaining a remedy or relief which most nearly reflects the remedy or relief which the party sought.

26. Additional Instruments. Each party shall, promptly upon the request of the other party

hereto, execute and have acknowledged and delivered to the other party any and all additional instruments and assurances reasonably requested or appropriate to evidence or give effect to the provisions of this Agreement.

27. Binding Effect. Except as limited by the provisions hereof relative to assignments, this Agreement shall be binding upon and inure to the benefit of Buyer, Seller, Escrow Agent and their respective heirs, executors, personal representatives, successors and permitted assigns, but shall not be enforceable by, nor inure to the benefit of, any third parties.

28. Applicable Law. This Agreement shall be governed by and construed in accordance with the laws of the State of California.

29. No Survival. Except as is otherwise in this Agreement specifically provided, no agreement, covenant, warranty or representation contained herein shall be deemed a continuing one or shall survive Close of Escrow or any termination of the Agreement.

30. Captions. The captions of the Sections of this Agreement are inserted for convenience only and shall not control or affect the meaning or construction of any provisions hereof.

31. Counterparts. This Agreement may be executed in counterparts, and any set of counterparts containing original signatures of both Buyer and Seller shall constitute an original Agreement for all purposes, but all of which shall constitute only one agreement.

32. Waiver. No provision of this Agreement, no breach thereof and no right or remedy becoming available upon the happening of such breach can be waived except by a written instrument dated and executed by the party against whom enforcement of such waiver is sought. All waivers shall apply to the particular instance and at the particular time only, and no waiver shall be deemed a continuing one or as applying to any other provision hereof or breach thereof of other available right or remedy.

33. Expiration of Offer/Date of Agreement. Neither the submission of this document by any party to the other for review, nor the revision thereof by any other party, shall constitute an offer or counter-offer of any kind by any party, and this Agreement shall become effective only upon execution and delivery thereof by the parties hereto. This Agreement is being executed first by Buyer and then presented to Seller for execution. Each party shall date this Agreement beside its signature as of the date of such signature. Upon Buyer’s execution, this Agreement shall constitute an offer, which if not accepted by Seller’s execution and delivery of this Agreement to Escrow Agent within five (5) business days after its receipt thereof from Buyer, shall be deemed to expire and be of no further force or effect unless extended or otherwise agreed to by Buyer. The date of this Agreement shall be the date of its acceptance by Seller, which date shall be entered on the first page of this Agreement by Seller or Escrow Agent.

34. Tax Deferred Exchange. Buyer acknowledges that Seller may desires to treat this transaction, if concluded, as the sale of the Property as a “like-kind” exchange under IRC Section1031. Buyer agrees to reasonably cooperate with Buyer in such transaction so long as (a) Closing is not delayed beyond the date provided in this Agreement, and (b) Buyer is not obligated to incur any expense in connection with such exchange.

35. Press Releases and Announcements. Prior to the Closing Date, none of the parties hereto shall issue any press release (or make any other public announcement) related to this Agreement or the transactions contemplated hereby without prior written approval of the other party hereto, except as may be necessary, in the opinion of counsel to the party seeking to make disclosure, to comply with the requirements of this Agreement or applicable law. If any such press release or public announcement is so required, the party making such disclosure shall consult with the other party prior to making such disclosure, and the parties shall

use all reasonable efforts, acting in good faith, to agree upon a text for such disclosure which is satisfactory to both parties. Buyer and Seller agree to instruct their respective brokers to comply with the provisions of this Section 35.

36. Records. Upon Buyer’s request, for a period of two (2) years after Closing, Seller shall make the operating statements and any and all books, records, tax returns of Seller (but not of the individual members, shareholders or partners of Seller), correspondence, financial data, Leases, delinquency reports and all other documents and matters maintained by Seller or its agents and relating to receipts and expenditures pertaining to the Property for the three (3) most recent full calendar years and the current calendar year (collectively, the “Records”) available to Buyer for inspection, copying and audit by Buyer’s designated accountants, and at Buyer’s expense. Seller shall provide Buyer, but without expense to Seller, with copies of, or access to, such factual information as may be reasonably requested by Buyer or its designated accountants, and in the possession or control of Seller, to enable Buyer to file any filings required by the Securities and Exchange Commission in connection with the purchase of the Property.

37. Natural Hazard Disclosure Requirement Compliance. Buyer and Seller acknowledge that Seller may be required to disclose if the Property lies within the following natural hazard areas or zones: (i) a special flood hazard area designated by the Federal Emergency Management Agency (California Civil Code Section 1103(c)(1)); (ii) an area of potential flooding (California Government Code Section 8589.4); (iii) a very high fire hazard severity zone (California Government Code Section 51178 et seq.); (iv) a wild land area that may contain substantial forest fire risks and hazards (Public Resources Code Section 4135); (v) earthquake fault zone (Public Resources Code Section 2622); or (vi) a seismic hazard zone (Public Resources Code Section 2696) (sometimes all of the preceding are herein collectively called the “Natural Hazard Matters”). Escrow Agent is hereby instructed to engage a disclosure provider (who, in such capacity, is herein called the “Natural Hazard Expert”) to examine the maps and other information specifically made available to the public by government agencies for the purposes of enabling Seller to fulfill its disclosure obligations, if and to the extent such obligations exist, with respect to the natural hazards referred to in California Civil Code Section 1103 and to report the result of its examination to Purchaser and Seller in writing. The written report prepared by the Natural Hazard Expert regarding the results of its full examination (the “Natural Hazard Report”) will fully and completely discharge Seller from its disclosure obligations referred to herein, if and to the extent any such obligations exist, and, for the purpose of this Agreement, the provisions of Civil Code Section 1103.4 regarding non-liability of Seller for errors or omissions not within its personal knowledge shall be deemed to apply and the Natural Hazard Expert shall be deemed to be an expert, dealing with matters within the scope of its expertise with respect to the examination and written report regarding the natural hazards referred to above. The Natural Hazard Report shall be prepared at Seller’s sole cost and expense. Buyer agrees to provide Seller with a written acknowledgment of its receipt of the Natural Hazard Report. Buyer may terminate the Agreement if the Natural Hazard Report discloses a condition which has a material adverse impact on the Property, so long as Buyer notifies Seller of Purchaser’s intention to terminate within three (3) business days of Buyer’s receipt of the Natural Hazard Report.

38. Audit Letter. Seller agrees to execute and deliver to Buyers auditors, within ten days after the opening of Escrow, an audit letter in the form attached hereto as Exhibit “I” (the “Audit Letter”).

39. Alternative Dispute Resolution. In the event of a dispute or claim with respect to this Agreement the parties shall submit such dispute or claim to binding arbitration. In such event, the parties shall agree upon an arbitrator with at least ten years experience in the Real Estate Industry and cooperate in the scheduling of an arbitration hearing. If the parties are unable to agree on an arbitrator within thirty (30) days after either party request arbitration, the dispute shall be submitted to the American Arbitration Association (“AAA”) on accordance with the AAA Arbitration Rules for the Real Estate Industry. The decision of the arbitrator shall be final and non-appealable. Judgment on the award rendered by the arbitrator may be entered

in any court of competent jurisdiction.
