THIS AGREEMENT, made and entered into as of this 25^th day of August, 2005, being the last date of execution hereof as set forth beneath the signatures below (the “Effective Date”) by and between ANDREW CORPORATION, an Illinois corporation (“Seller”), and KIMBALL HILL SUBURBAN CENTERS, L.L.C., an Illinois limited liability company, (“Purchaser”).

WITNESSETH:

WHEREAS, Seller is the owner of a parcel of real estate in the Village of Orland Park (“Village”) commonly known as 10500 West 153^rd Street, Orland Park, Illinois 60462 and consisting of improved industrial, office and warehouse property on approximately 103.2163 net acres of land (approximately 105.3671 gross acres) which parcel of real estate is legally described in Exhibit A attached hereto and made a part hereof (the “Land”); and

WHEREAS, Seller desires to sell, transfer and convey to Purchaser, and Purchaser desires to purchase from Seller the Land, together with all right, title and interest of Seller in and to all rights, privileges, easements, hereditaments and appurtenances in any way incident, appertaining or belonging to the Land and all buildings and improvements currently existing or hereafter constructed or installed on, in, over or under the Land in “as is” condition as hereinafter set forth, subject to and in accordance with each of the terms and conditions set forth below; and

WHEREAS, such sale, transfer and conveyance shall take place in two closings, the first to be for the parcel south of 153^rd Street comprising approximately 30 acres (“Parcel 1”) and the

second to be for the parcel north of 153^rd Street, comprising approximately 74 acres (“Parcel 2”), both to take place in the manner described herein.

NOW, THEREFORE, in consideration of the mutual covenants and agreements of the parties hereinafter set forth, the parties hereto mutually covenant and agree as follows:

1. AGREEMENT TO PURCHASE.

Seller agrees to sell, transfer and convey to Purchaser, and Purchaser agrees to purchase and accept from Seller the Land in two (2) closings under the terms and for the purchase price set forth herein below.

2. PURCHASE PRICE.

The total purchase price (the “Purchase Price”) to be paid to Seller by Purchaser for the Land shall be Twenty-Eight Million Five Hundred Thousand and no/100 Dollars ($28,500,000.00) payable as follows: Eleven Million Four Hundred Thousand and no/100 Dollars ($11,400,000.00) for Parcel 1 and Seventeen Million One Hundred Thousand and no/100 Dollars ($17,100,000.00) for Parcel 2 for a total of Twenty-Eight Million Five Hundred Thousand and no/100 Dollars ($28,500,000.00). The Purchase Price for each Parcel, plus or minus prorations, shall be payable at the Closing (as hereinafter defined) of such Parcel. The Purchase Price for each Parcel, plus or minus prorations as provided herein, shall be paid by Purchaser to Seller at the Closing thereof in immediate available funds wire transferred to an account or accounts specified by Seller. The Purchase Price shall not be affected by the actual acreage of the Land, as determined by the survey obtained by Purchaser.

3. EARNEST MONEY.

Within five (5) business days after the Effective Date, Purchaser shall deposit the sum of Five Hundred Thousand and no/100 Dollars ($500,000.00) (the “Initial Earnest

-2-

Money”) in a joint order escrow account (“Escrow”) with Escrowee (as hereinafter defined) for the mutual benefit of the parties. At the end of the Inspection and Feasibility Period, if this Agreement has not been terminated, the Initial Earnest Money shall become non-refundable to Purchaser (except in the event of Seller’s default) and Purchaser shall deposit into the escrow the additional sum of One Million Five Hundred Thousand and no/100 Dollars ($1,500,000.00) (the “Additional Earnest Money”) which shall also be non-refundable to Purchaser (except in the event of Seller’s default). The Initial Earnest Money and the Additional Escrow Money are collectively called the “Earnest Money.” All of the Earnest Money shall be applicable to the Purchase Price of Parcel 2. The Earnest Money shall be invested by the Escrowee, with the interest earned, less investment costs, payable to Purchaser.

4. CONVEYANCE.

Conveyance by Seller to Purchaser of each Parcel the Land shall be by Special Warranty Deed (the “Deed”) in recordable form, and such Deed shall convey to Purchaser good and marketable title in fee simple to the Parcel being conveyed, subject only to (i) general taxes not yet due and payable, (ii) exceptions set forth in Exhibit B attached hereto and made a part hereof and (iii) the additional exceptions referred to in Section 5 hereof (the “Permitted Exceptions”).

5. TITLE/SURVEY.

A. Title Commitment. Within twenty (20) days after the Date of this Agreement, Seller shall obtain and deliver to Purchaser a Commitment for Title Insurance (the “Title Commitment”) issued on or after the date hereof by Chicago Title Insurance Company (the “Title Company”) (which may be in nominal amount) showing Seller to be in title to the Land.

-3-

B. Survey. Prior to closing of Parcel 1, Purchaser shall obtain a staked 1999 ALTA/ACSM Land Title Survey of the Land prepared and currently certified by a registered Illinois Land Surveyor selected by Seller: (i) the exact boundaries and legal description of the Land and each of Parcels 1 and 2, (ii) any portions of the Land falling within any rights-of-way, (iii) all buildings or other structures located on the Land, (iv) all fencing or other improvements of every kind which might constitute encroachments in either direction over the boundaries, (v) all public or private utility or drainage easements or easements of passage of record and (vi) all areas which fall within any “floodplain,” designated as such by any federal, state or local authorities.

C. Title and Survey Defects. Seller agrees that the Title Commitment shall be subject only to: (i) general taxes not yet due and payable, (ii) the exceptions listed on Exhibit B and (iii) exceptions not objected to in writing by Purchaser as provided hereunder (collectively, the “Permitted Title Exceptions”). Purchaser shall, within fifteen (15) days after the receipt of the Title Commitment, notify Seller as to those exceptions stated on the Title Commitment to which Purchaser objects and, if Purchaser has obtained the survey prior to such date, notify Seller of those matters disclosed by the Survey to which Purchaser objects. Seller shall not be obligated to incur any costs to cure or correct or cause the title insurer to insure over objectionable or unacceptable matters of title or survey disclosures, with the exception that Seller shall be responsible for releasing any liens of a definite and ascertainable amount on or before the Closing Date for any Parcel. If Seller is unable or unwilling to cure or correct or cause the title insurer to insure over objectionable or unacceptable matters of title or survey disclosures, within ten (10) days after the date of Purchaser’s notice, Purchaser may elect by written notice to terminate this Agreement in which event the Initial Earnest Money shall be returned to Purchaser

-4-

and this Agreement shall be terminated except for Purchaser’s obligations to indemnify Seller and to restore the Land as provided herein (“Purchaser’s Indemnity and Restoration Obligations”). In the event no such notice is given within the time period permitted after each receipt by the Purchaser, Purchaser shall be deemed to have accepted the Title Commitment and/or the Survey and all exceptions contained in the Title Commitment and all matters disclosed by the Survey shall be deemed Permitted Exceptions, except for liens of a definite and ascertainable amount which Seller shall remove on or before the Closing Date for each Parcel. In the event the closing of the purchase of Parcel 1 occurs and only in such event, Seller shall provide a credit to Purchaser at Closing towards the Purchase Price of Parcel 1 (hereinafter defined) in the amount of Purchaser’s actual cost for obtaining the Survey. If the survey is not obtained by Purchaser within the later of (i) receipt of the Title Commitment or (ii) twenty (20) days after the Date of this Agreement, Purchaser shall have no right to object to any matters contained in the survey (except if Purchaser objects to a matter contained in the survey as a basis for terminating this Agreement prior to the expiration of the Inspection and Feasibility Period as provided in paragraph 6.D.) and all matters contained in the survey shall be Permitted Exceptions. Furthermore, if Purchaser fails to obtain the survey, Seller shall not be required to obtain Extended Coverage over matters of survey in the Title Policy delivered at the Closings.

6. INSPECTION AND FEASIBILITY PERIOD.

A. Purchaser shall have until forty-five (45) days after the Effective Date (the “Inspection and Feasibility Period”) to: (i) enter upon the Land, on reasonable notice to Seller and during normal business hours of Seller, to perform inspections of the Land (including the improvements located on the Land) as Purchaser deems advisable, (ii) investigate any title reports, title policies, plats, plans, engineering studies, surveys, soil boring reports and other

-5-

materials as may be in the possession of Seller (the “Seller’s Materials”) as described on Exhibit C attached hereto, (iii) make investigations and tests with regard to environmental matters and such other physical matters applicable to the Land or improvements thereon and (iv) make such other investigations as Purchaser deems appropriate, including the feasibility of obtaining approvals from the Village for Purchaser’s intended residential development.

B. Seller shall, contemporaneously with the execution of this Agreement, provide Purchaser with copies Seller’s Materials for Purchaser’s use during the Inspection and Feasibility Period. In the event this Agreement is terminated for any reason prior to the purchase of all of the Land by Purchaser, then Purchaser shall promptly return all copies of the Seller’s Materials to Seller, which shall be a condition to the return to Purchaser of any of the Earnest Money to which Purchaser may otherwise be entitled. Seller does not warrant the accuracy or completeness of such materials and shall have no liability to Purchaser if such materials are inaccurate or incomplete.

C. From and after the Effective Date, Purchaser and its employees, agents or independent contractors shall be permitted, on reasonable notice to Seller and during normal business hours of Seller, to come on to the Land (including the improvements located on the Land) to complete any physical investigations necessary for the performance of this Agreement, including soil tests and environmental studies. Purchaser shall, at its sole cost and expense repair any damage done to the Land or any improvements thereon in the course of any such inspections, and return the Land and improvements to the same or substantially the same condition they were in prior to such inspection. Such obligation shall survive Purchaser’s termination of this Agreement. Purchaser agrees to indemnify and hold Seller harmless from and against any and all mechanics liens or other claims for the providing of material or services upon the Land in

-6-

connection therewith and any other claims or causes of action arising out of any act, occurrence or omission of Purchaser or its employees, agents or independent contractors while on the Land, such obligation to survive Purchaser’s termination of this Agreement. Purchaser represents and warrants to Seller that Purchaser is presently insured under the following coverages and agrees to maintain policies providing such coverages in full force and effect in the same or greater amounts with respect to any activities hereunder which may take place on the Land during the pendency of this transaction:

	(a)		Comprehensive General Liability $500,000 — $500,000 for bodily injury $500,000 — $500,000 for property damage

	(b)		Commercial Umbrella Liability Policy $10,000,000 per occurrence

	(c)		Workmen’s Compensation Insurance Policy Policy limits according to Illinois law

The foregoing policies shall name Seller as an additional insured party and Purchaser shall deliver to Seller a Certificate of Insurance so providing, prior to Purchaser’s entry on to the Land.

D. On or before the expiration of the Inspection and Feasibility Period, Purchaser shall notify Seller, in writing, whether Purchaser intends to proceed with this Agreement. If Purchaser notifies Seller that it intends to proceed, this Agreement shall continue. If Purchaser notifies Seller that it does not intend to proceed or if Purchaser gives no notice within such period, then the Initial Earnest Money shall be returned to Purchaser and this Agreement shall be terminated, except for Purchaser’s Indemnity and Restoration Obligations, and within ten (10) days after the expiration of the Inspection and Feasibility Period, and as a condition to the return of the Initial Earnest Money, Purchaser shall deliver to Seller, at no cost or expense to Seller, all documents, tests and studies completed pursuant to this Section 6, together with all plats,

-7-

surveys, topographical surveys, soil tests, environmental tests, engineering and studies as may have then been prepared by or for Purchaser with respect to the Land, except for confidential financial and marketing studies, all of which shall be fully paid for. Purchaser does not warrant the accuracy or completeness of such materials and shall have no liability to Seller if such materials are inaccurate or incomplete.

7. REZONING.

Although there are no zoning contingencies in this Agreement, Seller may petition the Village for the rezoning of Parcels 1 and 2 for residential development, provided: (i) any rezoning by the Village of Parcel 1 or Parcel 2 or any agreements entered into by Purchaser with the Village in connection therewith shall by their terms, not be effective for either Parcel until the Closing of such Parcel, except with Seller’s consent, (ii) Purchaser shall keep Seller fully advised as to the progress of Purchaser’s efforts to rezone. Purchaser’s obligations to close on Parcels 1 and 2 shall not be contingent upon or otherwise be affected by Purchaser’s ability to achieve rezoning.

8. REPRESENTATIONS AND WARRANTIES.

F. Possession of each Parcel shall be given to Purchaser at the Closing of that Parcel.

10. ADJUSTMENTS.

A. All proratable items for each Parcel, if any, other than general real estate taxes shall be prorated as of the Closing Date for each Parcel, and such prorations shall be final unless otherwise agreed in writing by the parties.

B. General real estate taxes for each Parcel not due and payable at the time of Closing of that Parcel shall be adjusted pro rata on a per diem basis as of the Closing Date for that Parcel on the basis of 105% of the most recent ascertainable taxes, it being understood that for the purposes of prorations and adjustments, Seller shall be deemed the owner of a Parcel on the day immediately preceding the Closing Date for that Parcel and Purchaser shall be deemed the owner of the Parcel as of the Closing Date for that Parcel. Such general real estate tax

-13-

proration shall be final at the time of Closing. In the event either Parcel does not have a separate property index number of numbers, the parties shall calculate the tax proration on an acreage basis, taking into consideration and adjusting for the improvements located on the acreage.

11. REMOVAL OF PERSONAL PROPERTY, FIXTURES, EQUIPMENT AND COMPONENTS OF BUILDINGS.

The parties acknowledge that Purchaser is purchasing the Land for purposes of redevelopment and intends to demolish and remove the buildings and other improvements located thereon, upon acquisition, and that such buildings and other improvements have no value to Purchaser. Accordingly, Purchaser agrees that prior to the Closing of a Parcel, Seller may remove any and all personal property, fixtures, equipment or components of any building or other improvement on the Parcel, so long as (i) the removal does not affect the structural integrity of any building or create unsafe conditions in the building and (ii) such removal does not delay any closing. Seller agrees to indemnify and hold Purchaser harmless from and against any and all mechanics’ liens or other claims for the providing of material or services upon the Land in connection therewith and any other claims or causes of action arising out of any act, occurrence or omission of Seller or its employees, agents or independent contractors while on the Land.

12. CONDEMNATION.

In the event between the Effective Date and the date of Closing of either Parcel any condemnation or eminent domain proceedings are initiated which might result in the taking of a material portion of that Parcel, so as to materially interfere with Purchaser’s intended use of this

-14-

Parcel, Purchaser may elect (a) to terminate this Agreement, in which event all rights and obligations of the parties hereunder shall cease, except for Purchaser’s Indemnification and Restoration Obligations, and any Earnest Money in escrow shall be returned to Purchaser or (b) to consummate the closing of the Parcel, in which event Seller shall assign to Purchaser all of Seller’s right, title and interest in and to any award made in connection with such condemnation or eminent domain proceedings with respect to that Parcel. Seller shall immediately notify Purchaser in writing of the occurrence of any condemnation or eminent domain proceedings. Purchaser shall then notify Seller, within fifteen (15) days of Purchaser’s receipt of Seller’s notice, whether Purchaser elects to exercise its rights under clause (a) or clause (b) of this Section 12. If no election is made within such 15 days, Purchaser shall be deemed to have elected to close that Parcel. Purchaser’s right to terminate hereunder shall not apply to any taking by the Cook County Highway Department of right of way for the widening of 153^rd Street or improvements thereto.

13. REMEDIES.

A. In the event Seller is in default of any provisions of this Agreement, and has failed to cure such default within ten (10) days after receipt of written notice from Purchaser of such default, Purchaser may, as its sole remedy, either (i) elect to enforce the terms of this Agreement by an action of specific performance, or (ii) on written notice to Seller, terminate this Agreement, in which case, Seller shall cause the Earnest Money or any portion thereof then in Escrow to be returned to Purchaser. In the event of such termination, Purchaser shall not have any right to any lien or claim with respect to the Property, or to any damages, including consequential, incidental or indirect damages.

-15-

B. In the event Purchaser is in default of any provisions of this Agreement, and has failed to cure such default within ten (10) days after receipt of written notice from Seller of such default, the Earnest Money or any portion thereof as may be in the Escrow shall be paid to Seller as liquidated damages and the parties shall jointly direct the Escrowee to make such payment to Seller. In such event, Purchaser shall deliver to Seller, at no cost or expense to Seller, all documents tests and studies completed pursuant to Section 6, together with all plats, surveys, topographical surveys, soil tests, environmental tests, engineering and studies as may have then been prepared by or for Purchaser with respect to the Land, except for confidential financial and marketing studies, all of which shall be fully paid for. Purchaser does not warrant the accuracy or completeness of such materials and shall have no liability to Seller if such materials are inaccurate or incomplete. In the event Seller is required to expend attorneys’ fees to recover the Earnest Money from escrow, Purchaser shall also pay the amount of the attorneys’ fees so expended. Notwithstanding the foregoing, Purchaser shall also remain liable to Seller for Purchaser’s Indemnity and Restoration or other obligations of Purchaser under this Agreement that are intended to survive the termination of this Agreement. In order to cure a monetary default, Purchaser shall pay in addition to the amount owed, interest thereon at the rate of ten percent (10%) per annum from the due date to the date of payment.

14. MODIFICATIONS, WAIVERS, ETC.

A. Each Party reserves the right to waive any of the conditions precedent to its obligations hereunder. No such waiver, and no modification, amendment, discharge or change of this Agreement, except as otherwise provided herein shall be valid unless the same is in writing and signed by the party against which the enforcement of such modifications, waiver, amendment, discharge or change is sought.

-16-

B. This Agreement contains the entire agreement between the parties relating to the transaction contemplated hereby, and all prior or contemporaneous agreements, understandings, representations and statements, oral or written, are merged herein.

17. PURCHASER’S RELEASE AND INDEMNITY.

Purchaser expressly indemnifies, holds harmless, and releases Seller from, against, and in respect of any and all alleged or actual liabilities, obligations, claims, damages, costs, and expenses (including attorneys’ fees, fines, penalties, consequential damages, and

-19-

remedial costs) known or unknown, suspected or unsuspected, now or hereafter existing or discovered, whether arising before, at, or after the Closing Date, which in any manner or way arise out of, are related to, or incurred in connection with:

	(i)		the physical condition of the Land or any improvements thereon (including seismic, structural, or geotechnical condition);

	(ii)		the environmental condition of the Land or any improvements thereon;

	(iii)		the release from or migration to the Land or any improvements of any hazardous substance at any time prior to, on, or after the Closing Date or the presence, discharge, or disposal by any person or entity of any hazardous substances which are now, or have been, or may at any future time be present on or about the Land or any improvements thereon or have been or may be deposited at, disposed on, or released or migrated onto or from the Land or any improvements thereon; and
