PURCHASE AND SALE AGREEMENT --------------------------- THIS PURCHASE AND SALE AGREEMENT (this "Agreement") is made as of the 18th day of November, 1997, by and between PARK PLAZA VENTURE, an Illinois joint venture ("Seller"), and AHP OF TEXAS, INC., a Texas corporation ("Purchaser"). RECITALS -------- Seller is the owner of a certain parcel of real estate located in the City of Houston, County of Harris, State of Texas, which parcel is more particularly described in Exhibit A attached hereto (the "Land"), and that certain office building located thereon containing approximately 177,395 rentable square feet and commonly known as 1213 Hermann Drive, Houston, Texas or the "Park Plaza Office Building". Seller desires to sell to Purchaser, and Purchaser desires to purchase from Seller, the Property (as defined in Section 1 below), each in accordance with and subject to the terms and conditions set forth in this Agreement. THEREFORE, in consideration of the above Recitals, the mutual covenants and agreements herein set forth and the benefits to be derived therefrom, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Purchaser and Seller agree as follows: 1. PURCHASE AND SALE. Subject to and in accordance with the terms and conditions set forth in this Agreement, Purchaser shall purchase from Seller and Seller shall sell to Purchaser the Land, together with: (a) all buildings and improvements located on the Land (the "Improvements"), (b) Seller's right, title and interest in and to any and all appurtenant rights, easements, licenses and privileges presently thereon or relating or appertaining thereto, including any and all rights of way, land located within public streets, mineral rights and other appurtenances and hereditaments (collectively, the "Ancillary Rights"); (c) Seller's right, title and interest in and to the leases affecting the Property or any part thereof to the extent applicable to the period from and after the Closing (as such term is hereinafter defined) and all reversionary rights thereunder (the "Leases"); (d) all furniture, furnishings, fixtures, equipment, maintenance vehicles, tools and other tangible personal property owned by Seller, located on or within the Real Property (as defined in this Section 1) and used in connection therewith (the "Tangible Personal Property"); and (e) all right, title and interest of Seller under any and all of the maintenance, service, leasing, brokerage, advertising and other like contracts and agreements with respect to the ownership or operation of the Property (the "Service Contracts"), to the extent applicable to the period from and after the Closing. The Land, the Improvements and the Ancillary Rights are collectively referred to in this Agreement as the "Real Property". The Real Property, along with the items described in clauses (c) through (e) above are collectively referred to in this Agreement as the "Property". However, the term "Property" expressly excludes all property owned by tenants or other users or occupants of the Property (excluding items constituting fixtures under applicable law, but only to the extent that tenants under Leases do not retain and exercise a right to remove such items), all rights with respect to any refund of taxes applicable to any period prior to the Closing Date (as defined in Section 4(A) below), and all computers and computer-related equipment in the management office of the Property. 2. PURCHASE PRICE. The purchase price to be paid by Purchaser to Seller for the Property is Sixteen Million Nine Hundred Thousand and No/100 Dollars ($16,900,000.00) (the "Purchase Price"). The Purchase Price shall be paid as provided below. A. Earnest Money. Prior to the date hereof, and in accordance with the terms of a Letter of Intent and Modification Agreement dated October 15, 1997 (the "Letter Agreement"), Purchaser has delivered to Heritage Title Insurance Company of Austin, Inc. ("Escrow Agent"), initial earnest money 1 (the "Initial Earnest Money") in the sum of Fifty Thousand and No/100 Dollars ($50,000.00). Concurrently with the execution of this Agreement, Purchaser shall deposit with the Escrow Agent additional earnest money (the "Additional Earnest Money") in the sum of Three Hundred Thousand and No/100 Dollars ($300,000.00). The Initial Earnest Money and the Additional Earnest Money, together with any interest earned thereon net of investment costs, are referred to in this Agreement as the "Earnest Money". The Earnest Money shall be invested as Seller and Purchaser so direct; provided that if no such agreement as to investment is reached, the Earnest Money shall be deposited in an interest-bearing money market account with a federally insured bank or savings and loan. Any and all interest earned on the Earnest Money shall be reported to Purchaser's federal tax identification number unless the Earnest Money is distributed to Seller prior to Closing in accordance with this Agreement, in which event interest earned on the Earnest Money shall be reported to Seller's federal tax identification number. If the transaction closes in accordance with the terms of this Agreement, at Closing, the Earnest Money shall be delivered by Escrow Agent to Seller as partial payment of the Purchase Price. If the transaction fails to close due to a default on the part of Purchaser, the Earnest Money shall be delivered by Escrow Agent to Seller, such delivery to be without prejudice to the other rights and remedies of Seller due to such a default as provided in this Agreement or at law or in equity conferred. If the transaction fails to close due to a default on the part of Seller, the Earnest Money shall be delivered by Escrow Agent to Purchaser, and Purchaser shall have the remedy provided for in Section 7(A) below. B. Cash at Closing. At least one (1) business day prior to Closing, Purchaser shall deliver to Escrow Agent, for Escrow Agent to hold in escrow pending the Closing, and at Closing, Escrow Agent shall disburse to Seller from escrow, by wire transferred current federal funds, an amount equal to the Purchase Price, minus the sum of the Earnest Money which Seller receives at Closing from the Escrow Agent, and plus or minus, as the case may require, the closing prorations and adjustments to be made pursuant to Section 4(C) below. 3. EVIDENCE OF TITLE. ----------------- A. Title Commitment. Seller has heretofore obtained and caused to be delivered to Purchaser, and Purchaser acknowledges its receipt of, a commitment for a TLTA Owner's Title Insurance Policy, effective on October 27, 1997 (the "Title Commitment"), in the amount of the Purchase Price, issued by the Escrow Agent, as agent for Chicago Title Insurance Company (in such capacity, the "Title Insurer"), and containing the Title Insurer's commitment to issue a TLTA Owner's Title Insurance Policy to Purchaser at Closing which policy shall be revised as follows (the "Title Policy"): (i) the exception relating to restrictions against the Real Property shall be deleted or limited to restrictions which are Permitted Exceptions (as defined in this Section 3(A) below); (ii) the exception relating to discrepancies, conflicts, shortages in area or boundary lines, or any encroachments or protrusions, or any overlapping of improvements shall be deleted (except with respect to shortages in area), subject to, without limitation, Purchaser fulfilling its obligations under Sections 3(B) and 4(D) below; (iii) the exception relating to ad valorem taxes shall except only standby fees, taxes and assessments by any taxing authority owing for the current year of Closing and subsequent years and subsequent taxes and assessments by any taxing authority for prior years due to change in the usage or ownership of the Real Property; (iv) the exception relating to inspections of the Property shall be deleted, provided that Purchaser signs and delivers to the Title Insurer, the appropriate waiver forms; (v) the exception relating to the completion and acceptance by "owner" of all improvements or repairs to the Real Property, the payment in full of all contractors, subcontractors, laborers and suppliers and the attachment of mechanics', laborers', materialmens' or similar liens shall be deleted; (vi) the exception relating to rights of parties in possession shall be limited to the rights of tenants in possession under the Leases; and (vii) the conditions to the effectiveness of the Title Policy contained in Schedule C thereto, shall be deleted in their entirety. At Closing, the conveyance of the Property to Purchaser shall be made subject only to those exceptions to title which are 2 more fully described on Exhibit B attached hereto (which, together with any exceptions to title which become Permitted Exceptions pursuant to this Section 3 below, are collectively referred to as the "Permitted Exceptions"). B. Survey. Purchaser has heretofore obtained for itself, and shall deliver to Seller within two (2) days of the date hereof a copy of, a survey of the Real Property prepared by a surveyor licensed in the State of Texas in accordance with the current Texas Surveyors Association Standards and Specifications for a Category 1A, Condition II survey, and sufficient to modify the standard title exception for area and boundary to read "Shortages in Area" (the "Survey"). The Survey shall include a certification substantially in the form of Exhibit H attached hereto. C. Review of Title Commitment and Survey. If the Title Commitment or Survey disclose exceptions to title other than those Permitted Exceptions set forth on Exhibit B, then Purchaser shall have until 5:00 p.m. (Chicago, Illinois time) on November 23, 1997 to notify Seller of any such exceptions to title to which Purchaser objects. If any additional exceptions to title arise between the date of the Title Commitment, the Survey and the Closing, then Purchaser shall have five days after its receipt of notice of same within which to notify Seller of any such exceptions to title to which Purchaser objects. Any such exceptions to title not objected to by Purchaser as aforesaid shall become Permitted Exceptions. If Purchaser objects to any such exceptions to title, Seller shall have until Closing (but in any event at least fifteen days after it receives notice of Purchaser's objection(s)) to remove such exceptions to title, which removal may be by waiver or endorsement by the Title Insurer reasonably acceptable to Purchaser. If Seller fails to remove any such exceptions to title as aforesaid, Purchaser may, as its sole and exclusive remedy, terminate this Agreement and obtain a return of the Earnest Money. If Purchaser does not elect to terminate this Agreement, Purchaser shall consummate the Closing and accept title to the Property subject to all such exceptions to title, in which event, all such exceptions to title shall also be deemed Permitted Exceptions. 4. CLOSING. ------- A. Closing Date. The payment of the Purchase Price, the transfer of title to the Property, and the satisfaction of all other terms and conditions of this Agreement (the "Closing") shall occur at 10:00 a.m. on December 18, 1997, at the Chicago, Illinois, office of the Title Insurer, or at such other time and place as Seller and Purchaser shall agree in writing (the date of Closing being referred to as the "Closing Date"). If the scheduled date for Closing above provided for falls on a Saturday, Sunday or legal holiday, then the Closing Date shall be the next business day. B. Closing Documents and Deliveries. At least one (1) business day prior to Closing, Seller shall execute and send by overnight courier to Escrow Agent the documents identified in items (i) through (v) of this paragraph, and shall send by facsimile transmission to Escrow Agent and Purchaser, an unexecuted copy of the document identified in item (vi) of this paragraph; and provided that Escrow Agent has received all of the deposits from Purchaser and Seller required pursuant to this Section 4(B), at Closing, Escrow Agent shall cause to be completed all of the following: (i) cause to be recorded in the official records of Harris County, Texas applicable to real property and to ownership thereof (the "Official Records") a "Special Warranty" Deed conveying title to the Real Property, subject solely to the Permitted Exceptions, and in the form attached hereto as Exhibit I; (ii) deliver to Purchaser a "special" warranty bill of sale sufficient to transfer to Purchaser title to the Tangible Personal Property and expressly disclaiming any warranties of title other than as to matters created by or through Seller and not otherwise; (iii) deliver to Purchaser, copies of letters advising tenants under the Leases of the change in ownership of the Property in the form attached hereto as Exhibit C (the original letters shall be sent to each tenant by Seller upon Closing); and deliver to Purchaser, copies of similar letters advising providers of services under the Service 3 Contracts in the form attached hereto as Exhibit D (the original letters shall be sent to each vendor by Seller upon Closing); (iv) cause to be recorded in the Official Records, the Assignment and Assumption of Leases, Service Contracts and Security Deposits, in the form attached hereto as Exhibit E; (v) an affidavit stating, under penalty of perjury, Seller's U.S. taxpayer identification number and that Seller is not a foreign person within the meaning of Section 1445 of the Internal Revenue Code; and (vi) draft copy of the closing statement setting forth the prorations and adjustments to the Purchase Price as required by Section 4(C) below (the "Closing Statement") (a signed counterpart of the final Closing Statement shall be sent by facsimile transmission to Escrow Agent from Seller on the Closing Date with original counterparts to follow by overnight courier for disbursement to Purchaser). At least one (1) business day prior to Closing, Purchaser shall execute and send by overnight courier to Escrow Agent the following documents and deliveries: (i) counterparts of the Assignment and Assumption of Leases, Service Contracts and Security Deposits, in the form attached hereto as Exhibit E (to be recorded at Closing as aforesaid); and (ii) counterparts of the Closing Statement for attachment to the final Closing Statement by Escrow Agent upon Closing. At least one (1) business day prior to Closing, Purchaser shall wire transfer the funds described in Section 2(B) above. C. Closing Prorations and Adjustments. Each of the following provisions shall survive the Closing: (i) The following items are to be prorated or adjusted (as appropriate) as of the close of business on the Closing Date, it being understood that for purposes of prorations and adjustments, Seller shall be deemed the owner of the Property on such day and Purchaser shall be deemed the owner of the Property as of the day after the Closing Date: (a) real estate and personal property taxes and assessments (on the basis of the most recent ascertainable tax bill if the current bill is not then available); (b) the "minimum" or "base" rent payable by tenants under the Leases; provided, however, that rent and all other sums which are due and payable to Seller by any tenant but uncollected as of the Closing shall not be adjusted or prorated, but Purchaser shall cause the rent and other sums for the period prior to Closing to be remitted to Seller if, as and when collected. At Closing, Seller shall deliver to Purchaser a schedule of all such past due but uncollected rent and other sums owed by tenants. Purchaser shall include the amount of such rent and other sums in the first bills thereafter submitted to the tenants in question after the Closing, and shall continue to do so for twelve (12) months thereafter. During such twelve (12) month period, Purchaser shall promptly deliver to Seller a copy of each such bill submitted to tenants. Purchaser shall promptly remit to Seller any such rent or other sums paid by scheduled tenants, but only if a deficiency in the then current rent is not thereby created. To the extent not set forth on said schedule, reimbursement of real estate taxes payable, common area maintenance, utility charges, water and sewer charges, insurance and association dues and assessments and all other charges to or contributions by tenants under the Leases shall be prorated in the same manner as provided for "minimum" or "base" rent; (c) with respect to tenant improvement costs or leasing commissions relating to Leases, or any modification, amendment, restatement or renewal thereto, executed on or after October 16, 1997 (referred to as a "New Lease"), Seller and Purchaser agree that such costs and commissions shall be prorated over the term of any New Lease with Seller being responsible for a portion of such costs and commissions based on the ratio of base rent payments received by Seller through the Closing Date to the total base rent payable over the term of the particular New Lease; 4 (d) the amount of security deposits paid under the Leases and unapplied at Closing shall be a credit to Purchaser; (e) water, electric, telephone and all other utility and fuel charges, fuel on hand (at cost plus sales tax), and any deposits with utility companies (to the extent possible, utility prorations will be handled by meter readings on the day immediately preceding the Closing Date); (f) amounts paid or payable under the Service Contracts; (g) assignable license and permit fees; and (h) other similar items of income and expenses of operation. (ii) Notwithstanding the foregoing, Seller shall in all events be entitled to retain amounts paid by tenants (referred to herein as "Tenant Reimbursements") for real estate taxes and assessments, and common area and operating expenses (collectively, "Tenant Reimbursable Expenses") as of the Closing to the extent not in excess of the actual amount of such Tenant Reimbursable Expenses paid by Seller for the period prior to the Closing Date. Seller shall be responsible for the reconciliation with tenants of Tenant Reimbursements and Tenant Reimbursable Expenses for the calendar year 1997. Purchaser agrees to cooperate with Seller in providing any information required to complete such reconciliation. (a) if and to the extent that the amount of Tenant Reimbursements collected by Seller for 1997 is less than the amount of Tenant Reimbursable Expenses paid by Seller with respect to 1997 and for which Seller is entitled to recover under the terms of the Leases, Purchaser shall: (1) to the extent such amounts have already been collected by Purchaser from the tenants with respect to any period prior to Closing, promptly remit such amounts to Seller but only if the applicable tenant is otherwise current in the payment of all obligations due for the period following Closing; and (2) to the extent such amounts have not yet been collected from tenants, Purchaser shall promptly bill the tenants for such amounts and continue to bill such tenants for such amounts each month for six (6) months thereafter, and, promptly upon receipt thereof, pay such amounts to Seller; and (b) if and to the extent that the amount of Tenant Reimbursements collected by Seller for 1997 exceeds the amount of Tenant Reimbursable Expenses paid by Seller with respect to 1997 and for which Seller is entitled to recover under the terms of the Leases, Seller shall remit such excess amounts to Purchaser, provided, that: (1) Purchaser shall be thereafter obligated to promptly remit the applicable portion to the particular tenants, if any, entitled thereto; and (2) Purchaser shall indemnify, defend and hold Seller, its beneficiaries, their partners, and their respective directors, officers, employees and agents, and each of them, harmless from and against any losses, claims, damages and liabilities, including, without limitation, reasonable attorneys' fees and expenses incurred in connection therewith, arising out of or resulting from Purchaser's failure to remit any such amounts to tenants in accordance with the provisions hereof. (iii) For purposes of this Section 4(C), the amount of any expense credited by one party to the other shall be deemed an expense paid by that party. D. Transaction Costs. Purchaser shall pay for the cost of the Survey, the premiums for the Title Policy and all endorsements or revisions thereto, to the extent such premiums exceed the premium payable for the "base policy". Seller shall pay for the premium for the base coverage under the Title Policy and for any documentary stamps. Seller and Purchaser shall each pay one-half (1/2) of all 5 escrow fees, whether or not the Closing occurs. Seller and Purchaser shall, however, be responsible for the fees of their respective attorneys. E. Possession. Upon Closing, Seller shall deliver to Purchaser possession of the Property, subject to such matters as are permitted by or pursuant to this Agreement. 5. CASUALTY LOSS AND CONDEMNATION. If, prior to Closing, the Property or any part thereof shall be condemned or destroyed or damaged by fire or other casualty, or the condition of the Property otherwise materially and adversely changes, Seller shall promptly so notify Purchaser. The following events shall hereinafter be referred to as a "Material Loss": (i) any condemnation, casualty or other material adverse change in the condition of the Property which is insured under Seller's existing insurance coverage ("Seller's Coverage"), provided that the reasonable estimated cost to repair or restore such condemnation, casualty or other material adverse change exceeds Two Hundred Fifty Thousand Dollars ($250,000); (ii) a material adverse change in the condition of the Property which is not insured under the Seller's Coverage, provided that the reasonable estimated cost to repair or restore such material adverse change exceeds One Hundred Twenty-Five Thousand Dollars ($125,000); and (iii) any casualty or other material adverse change in the condition of the Property which would require more than ninety (90) days to restore and repair. In the event of a Material Loss, Purchaser shall have the option to terminate this Agreement by giving notice to Seller within fifteen days of Seller's request that the option be exercised, and the Closing Date shall be extended, if necessary, to provide Purchaser with such fifteen day period to make its election pursuant to this Section 5. Notwithstanding clause (iii) above in this Section 5, a Material Loss shall not have occurred solely because any such restoration or repair cannot be completed within such ninety (90) day period due to shortages of supply or labor, strikes, weather conditions, acts of God or generally due to reasons outside of the direct control of Seller, financial ability excepted. If the condemnation, destruction, damage or other material adverse change in the condition of the Property does not result in a Material Loss, or if Purchaser fails to terminate this Agreement following a Material Loss as provided herein, then Seller and Purchaser shall consummate the transaction contemplated by this Agreement notwithstanding such condemnation, destruction, damage or material adverse change in condition. If the transaction contemplated by this Agreement is consummated, Purchaser shall be entitled to receive the condemnation proceeds or settle the loss under all policies of insurance applicable to the destruction or damage and receive the proceeds of insurance applicable thereto, if any, and Seller shall, at Closing, allow Purchaser a credit against the Purchase Price in an amount equal to any deductibles on applicable policies and shall also execute and deliver to Purchaser all customary proofs of loss, assignments of claims and other similar items. In such event, Seller shall cooperate with and assist Purchaser, at no cost or liability to Seller, with Purchaser's efforts to obtain the proceeds of insurance and/or condemnation awards applicable to the Property. If Purchaser elects to terminate this Agreement, the Earnest Money shall be returned to Purchaser by the Escrow Agent, in which event this Agreement shall, without further action of the parties, terminate and become null and void and neither party shall have any further rights or obligations under this Agreement, except those which expressly survive termination of this Agreement. 6. BROKERAGE. Seller agrees to pay upon Closing, but not otherwise, a brokerage commission due to Cushman & Wakefield of Texas, Inc., for services rendered in connection with the sale and purchase of the Property. Seller and Purchaser acknowledge and agree that Cushman & Wakefield of Texas, Inc. is obligated to pay a portion of its commission to LaSalle Partners Management Limited. Seller and Purchaser shall each indemnify and hold the other harmless from and against any and all claims of all brokers and finders (other than Cushman & Wakefield of Texas, Inc. and LaSalle Partners Management Limited) claiming by, through or under the indemnifying party and in any way related to the sale and purchase of the Property, this Agreement or otherwise, including, without limitation, attorneys' fees and expenses incurred by the indemnified party in connection with such claim. The foregoing provisions shall survive the Closing or any termination of this Agreement. 6 7. DEFAULT AND REMEDIES. -------------------- A. Seller Default. Notwithstanding anything to the contrary contained in this Agreement, if Seller fails to perform in accordance with the terms of this Agreement, then, as Purchaser's sole and exclusive remedy hereunder and at Purchaser's option, either: (i) the Earnest Money shall be returned to Purchaser, in which event this Agreement shall terminate and become null and void, and neither party shall have any rights or obligations under this Agreement, except for those provisions that expressly survive termination of this Agreement; or (ii) upon notice to Seller not less than ten (10) days after Purchaser becomes aware of such failure, and provided an action is filed within thirty (30) days thereafter, Purchaser may seek specific performance of this Agreement, but not damages. Purchaser's failure to seek specific performance as aforesaid shall constitute its election to proceed under clause (i) above. B. Purchaser Default. If Purchaser fails to perform in accordance with the terms of this Agreement, the Earnest Money may be retained by Seller as liquidated damages and as Seller's sole and exclusive remedy, and this Agreement shall automatically terminate, except for those provisions of this Agreement that expressly survive the termination hereof. If Purchaser does not deposit with the Escrow Agent the Additional Earnest Money as provided for in Section 2(A) above, the sum of $350,000.00 shall nonetheless be recoverable by Seller from Purchaser as Earnest Money and without prejudice to Seller's other rights and remedies. Purchaser and Seller acknowledge and agree that the Earnest Money is a reasonable estimate of and bears a reasonable relationship to the damages that would be suffered and costs incurred by Seller as a result of having withdrawn the Property from sale and the failure of Closing to occur due to a default of Purchaser under this Agreement; that the actual damages suffered and costs incurred by Seller as a result of such withdrawal and failure to close due to a default of Purchaser under this Agreement would be extremely difficult and impractical to determine; that Purchaser seeks to limit its liability under this Agreement to the amount of the Earnest Money in the event this Agreement is terminated and the transaction contemplated by this Agreement does not close due to a default of Purchaser under this Agreement; and that the Earnest Money shall be and constitute valid liquidated damages. C. Post-Closing Remedies. After Closing, Seller and Purchaser shall, subject to the terms and conditions of this Agreement, have such rights and remedies as are available at law or in equity, except that neither Seller nor Purchaser shall be entitled to recover from the other consequential or special damages. This provision shall survive the Closing. 8. CONDITIONS PRECEDENT. -------------------- A. Review Period. Subject to Sections 10(G) and 10(J) below and the provisions of the Letter Agreement, Purchaser acknowledges that prior to the date hereof, it has had an opportunity to inspect the Property, review all "Disclosures" (as hereinafter defined) provided by Seller, review copies of the Leases, the most recent real estate tax statements with respect to the Property, the most recent sewer and water bills with respect to the Property, the Service Contracts, bills for electricity and for fuel used to operate the heating and air conditioning systems controlled by Seller at the Property covering the previous twelve months, correspondence between tenants and Seller (as landlord), (except for any of such items that contain privileged information), billings to tenants for Tenant Reimbursables and invoices for Tenant Reimbursable Expenses, any plans for the buildings or other Improvements located, or proposed to be located, on the Property, and any licenses or permits issued to Seller in connection with the ownership and operation of the Property, and make such other inquiries and investigations and obtain such reports and analyses it deemed adequate in connection with its decision to purchase the Property, 7 and, as a result thereof, Purchaser agrees that, except as specifically set forth in this Agreement, it shall purchase the Property in its "AS IS, WHERE IS" condition. B. Estoppel Certificates. As a condition to Purchaser's obligation to close hereunder, Purchaser shall have received estoppel certificates ("Estoppel Certificates"), dated no more than thirty (30) days prior to Closing, from tenants occupying not less than seventy-five percent (75%) of the rentable space actually leased as of the date of Closing pursuant to valid and existing Leases and in the form and content as set forth herein (the aforesaid acceptable Estoppel Certificates to be delivered are collectively referred to as the "Required Estoppel Certificates"). The Estoppel Certificates shall be in the form of Exhibit F attached hereto (the "Form Tenant Estoppel Certificate"). The Estoppel Certificates executed by tenants shall be in substantially the form of (i) the estoppel certificate required to be given by any such tenant pursuant to its Lease, or (ii) the Form Tenant Estoppel Certificate, except that an Estoppel Certificate executed by a tenant shall be deemed an acceptable Estoppel Certificate for purposes of this Section 8(B) as long as it contains the information set forth in items 1 through 9, 11 and 13 on the Form Tenant Estoppel Certificate, and that an Estoppel Certificate shall be deemed an acceptable Estoppel Certificate for purposes of this Section 8(B) if it contains the qualification by the tenant of any statement as being to the best of its knowledge or as being subject to any similar qualification. Seller shall endeavor to obtain Estoppel Certificates from all tenants leasing space in the Improvements prior to Closing. If Seller is unable to provide to Purchaser the Required Estoppel Certificates on or before Closing, then Purchaser may elect, by written notice to Seller given on the Closing Date, either: (i) not to purchase the Property, in which event the Earnest Money shall be returned to Purchaser, at which time this Agreement shall terminate and become null and void and neither party shall have any further rights or obligations under this Agreement, except those which expressly survive termination of this Agreement; or (ii) elect to purchase the Property notwithstanding Seller's inability to provide the Required Estoppel Certificates, in which event Purchaser shall be deemed to have waived the condition contained in this Section 8(B). If Purchaser fails to deliver such written notice as described above, Purchaser shall be deemed to have elected item (ii) above. C. Accuracy of Seller's Representations and Warranties. As a condition to the obligations of Purchaser to close hereunder, Seller shall have fully performed its material obligations under this Agreement and each of Seller's representations and warranties set forth in Section 9 below shall be true and correct as of the Closing, as modified by any Pre-Closing Disclosures (as defined in Section 9(B) below). Notwithstanding the foregoing, if Seller makes any Pre-Closing Disclosure to Purchaser, Purchaser shall have the right to terminate this Agreement and receive the return of the Earnest Money by delivering written notice thereof to Seller on or before the earlier of the Closing, or the fifth business day after Purchaser receives written notice of such Pre-Closing Disclosure. If Purchaser does not terminate this Agreement pursuant to its rights under this Section 8(C), then such representations and warranties shall be deemed modified to conform them to the Pre-Closing Disclosure. D. Title. As a condition to the obligations of Purchaser to close hereunder, concurrently with the Closing, the Title Insurer shall issue the Title Policy or commit to issue the Title Policy in the form of a "marked-up" Title Commitment. E. Conditions Precedent to Seller's Obligations. The obligation of Seller to consummate the transaction hereunder shall be subject to the fulfillment on or before the Closing Date of all of the following conditions, any or all of which may be waived by Seller in its sole discretion: (i) Escrow Agent shall have received the Purchase Price as adjusted pursuant to and payable in the manner provided for in this Agreement. 8 (ii) Purchaser shall have performed and observed, in all material respects, all covenants and agreements of this Agreement to be performed and observed by Purchaser as of the Closing Date. 9. REPRESENTATIONS, WARRANTIES AND COVENANTS. ----------------------------------------- A. Seller's Representations and Warranties. Subject to Section 9(C) below, Seller represents and warrants to Purchaser that, as of the date of this Agreement: (i) Seller holds good and indefeasible fee simple title to the Real Property (free and clear of all exceptions to title other than the Permitted Exceptions). (ii) Seller is a joint venture, duly organized and in good standing under the laws of the State of Illinois. Seller has the power and authority under Seller's joint venture agreement ("Seller's Organizational Documents"), to sell, transfer, convey and deliver the Property to be sold and purchased hereunder, and all action and approvals required thereunder have been duly taken and obtained. (iii) The execution and delivery of this Agreement, the consummation of the transactions provided for herein and the fulfillment of the terms hereof have been duly authorized by all required actions and will not result in a breach of any of the terms or provisions of, or constitute a default under, any provision of Seller's Organizational Documents. This Agreement is binding upon Seller and enforceable against Seller in accordance with its terms subject to the effect of the federal and state bankruptcy laws, insolvency, reorganization, receivership, moratorium, and other similar laws, and principles of equity and the doctrine of commercial reasonableness. (iv) Seller has not received from any governmental authority any written notice of (a) any condemnation of the Property or any part thereof, or (b) except as set forth on Exhibit J attached hereto, any material violation of any, state or federal law, rule or regulation concerning the Property or any part thereof which has not been cured prior to the date of this Agreement; provided, however, that Seller makes no representation or warranty with respect to (1) the information or matters disclosed in the items set forth in Exhibit K attached hereto, and (2) the Property's compliance with the Americans with Disabilities Act, as the same applies to any individual leased premises in the Building. (v) Except as set forth on Exhibit G attached hereto, Seller has not been served with any material litigation which is still pending against Seller with respect to its ownership or operation of the Property or any portion thereof. B. Representations Remade. As of Closing, Seller shall be deemed to remake and restate the representations set forth in Sections 9(A)(ii) through (iv) except that the representations shall be updated by delivering written notice to Purchaser in order to reflect any fact, matter or circumstance which Seller's Chicago, Illinois representatives become aware of that would make any of Seller's representations or warranties contained herein untrue or incorrect (any such disclosure being referred to as a "Pre-Closing Disclosure"). Notwithstanding the foregoing, the obligation to update the representations and warranties as provided herein shall not relieve Seller from liability (if any) under any other provision of this Agreement. C. Survival. The representation and warranty set forth in Section 9(A)(i) shall not survive the Closing. The representations and warranties set forth in Section 9(A)(ii) through 9 Section 9(A)(v), subject to modifications thereto as a result of any Pre-Closing Disclosure, shall survive the Closing, but only for a period of six (6) months thereafter, and not otherwise. D. Covenants. Seller hereby covenants and agrees with Purchaser that: (i) From and after October 16, 1997 through the date hereof, Seller has delivered for Purchaser's review, a copy of any New Lease (as defined above) or new Service Contract, or any modification, amendment, restatement or renewal of any existing Service Contracts to the extent required in the Seller's ordinary course of business (collectively, "New Agreements"). (ii) From and after the date hereof, Seller shall not enter into any New Agreement without Purchaser's prior written consent, which will not be unreasonably withheld or delayed. If Purchaser does not respond in writing to Seller's request for approval or disapproval of a New Agreement within ten (10) days after Purchaser's receipt of Seller's request, Purchaser shall be conclusively deemed to have approved of such New Agreement. In the event Purchaser disapproves such New Agreement by giving Seller written notice thereof, and thereafter Seller enters into such New Agreement, Purchaser shall have the right to terminate this Agreement, and if Purchaser so elects to terminate this Agreement, the Earnest Money shall be returned to Purchaser by the Escrow Agent, in which event this Agreement shall, without further action of the parties, terminate and become null and void and neither party shall have any further rights or obligations under this Agreement, except those which expressly survive termination of this Agreement. 10. MISCELLANEOUS. ------------- A. Entire Agreement.
