3.2 Physical Inspection. (a) In addition to the items set forth in Section 3.1, Seller will make the Property available for inspection by Purchaser, and Purchaser shall, at Purchaser’s risk, conduct such engineering, environmental and/or market and economic feasibility studies of the Property and undertake such physical inspection of the Property as Purchaser deems appropriate as soon as possible after the Effective Date of this Agreement.

In the event any part of the Property is damaged or excavated by Purchaser, its employees, agents or independent contractors, Purchaser agrees in the event its purchase hereunder is not consummated, to make such additional payments to Seller as may be reasonably required to return the Property to its condition immediately prior to such damage or excavation.

(g) Notwithstanding any provision to the contrary herein, Purchaser’s obligations under this Section 3.2 shall survive the expiration or termination of this Agreement and shall survive Closing.

Purchaser shall have a period ending as of the Closing Date to conduct its inspection of the documents delivered or made available for inspection in accordance with Section 3.1 and to conduct a physical inspection of the Property as set forth in Section 3.2 (the “Feasibility Period”). If Purchaser, in its sole and absolute discretion, is for any reason not satisfied with the Property, or if Purchaser determines, for any reason or for no reason whatsoever, not to purchase the Property, then Purchaser shall have the absolute right at any time at or prior to 5:00 P.M. (Eastern time) on the last day of the Feasibility Period (the “Termination Notice Date”) to terminate this Agreement, such termination right to be exercised by written notice (the “Termination Notice”) to such effect given by or on behalf of Purchaser to Seller in the manner provided for herein. Upon receipt of the Termination Notice, this Agreement shall terminate, and the Escrow Agent shall return the Deposit to Purchaser, and neither party shall have any further liability or obligation hereunder to any other, except for any obligations that expressly survive the termination of this Agreement (collectively, the “Surviving Obligations”). If Purchaser fails to provide the Termination Notice on or before 5:00 P.M. on the Termination Notice Date, Purchaser shall be deemed to have approved such inspections, and this Agreement shall remain in full force and effect. If Purchaser terminates this Agreement, then: (i) the Deposit shall be returned to Purchaser, with all interest accrued thereon, (ii) all Seller materials provided to Purchaser pursuant to Section 3.1 shall be returned to Seller, together with copies of all engineering, environmental and other studies relating to the Property prepared by, for or on behalf of, Purchaser, shall be delivered to Seller, and (iii) this Agreement shall terminate and no longer shall be of any force or effect, and neither party shall have any further liability or obligation hereunder to the other party, except for the Surviving Obligations.

3.4. Review of Title and Survey.

3.4.1 Examination of Title. Seller shall obtain a current commitment for title insurance (the “Commitment”) issued by Escrow Agent (the “Title Company”), agreeing to issue an ALTA-Form B (1992) owner’s title insurance policy or equivalent form reasonably acceptable to Purchaser with respect to the Property, in the amount of the Purchase Price, dated as of the Closing Date, indicating title to the Property is vested in Purchaser (or Purchaser’s designees pursuant to Article XII) subject only to Permitted Exceptions (as defined herein). Seller shall obtain, at its sole cost and expense, a new or updated survey of the Property (the “Survey”). Purchaser will have until Termination Notice Date to examine title to the Property and to notify Seller in writing of any objections to title that may be revealed by Purchaser’s examination (called herein the “Notice of Title Objections”). Purchaser will deliver to Seller, promptly after its receipt by Purchaser, a copy of the Commitment and a copy of the Survey. The Notice of Title Objections, if and when delivered by Purchaser to Seller, shall enumerate all title exceptions or objections that are unacceptable to Purchaser (and all such title exceptions and objections that are not so enumerated as unacceptable to Purchaser shall be deemed to be acceptable and shall become Permitted Exceptions for all purposes of this Agreement). In the event that Purchaser fails to give a Notice of Title Objections on or before the Termination Notice Date, then such failure to timely notify Seller will constitute a waiver of such right to object to any title defects, and this Agreement will remain in full force and effect in accordance with its terms and the purchase and sale contemplated hereby will be closed as herein provided, with all exceptions shown on the Commitment being deemed acceptable to Purchaser and becoming Permitted Exceptions for all purposes of this Agreement.

3.4.2 Cure of Title Objections. If Purchaser has timely given a Notice of Title Objections as set forth above, Seller will have the right, but not the obligation (unless otherwise expressly set forth below in this subsection), at any time on or prior to the Closing Date, to cure any such objections. If Seller timely cures such objections, or, if such objections are such that the same cannot be cured on or prior to Closing, and Seller has commenced curing such objections and thereafter diligently proceeds to effect such cure (but in no event beyond forty-five (45) days unless agreed to by Purchaser), then this Agreement shall continue in force and effect, and the Closing Date shall be adjourned accordingly. If Seller is unable to, or chooses not to, cure such objections within the time permitted, this Agreement shall terminate, Seller shall instruct the Escrow Agent to return the Deposit to Purchaser, and neither party shall have any further obligations hereunder except for the Surviving Obligations. Notwithstanding the foregoing, however, Purchaser may waive such objections that Seller is unable to or chooses not to cure, and upon receipt by Seller of such waiver in full from Purchaser within ten (10) days of notice from Seller that it is unable or chooses not to cure such objections, this Agreement shall remain in full force and effect with no reduction in the Purchase Price.

Notwithstanding anything set forth in this Agreement to the contrary, whether or not Purchaser objects to the same, Seller shall have an obligation (i) to pay (at or prior to Closing) any amount due in order to satisfy or remove from record title by bonding off or otherwise any mortgages, deeds of trust and liens or encumbrances that secure the payment of money (the “Monetary Liens”), and Seller may authorize Escrow Agent to deduct from the Purchase Price at Closing the amount necessary to pay off or discharge any Monetary Liens, and (ii) to cure and remove from record title (at or prior to Closing) all liens and other title exceptions created or filed against the Property after the date of this Agreement (any such liens and other title exceptions, together with the Monetary Liens, the “Mandatory Cure Items”).

Any easements, covenants, restrictions, exceptions of record (other than Mandatory Cure Items) that are shown on the Commitment to which Purchaser has not objected as set forth above, together with

4

(a) any and all present and future zoning laws, ordinances, resolutions and regulations of any municipal, county state or federal governments, or agency thereof, now or hereafter having or acquiring jurisdiction over the Property and the use and improvement thereof, (b) any state of facts that a current and accurate survey may show, (c) any lien for real estate taxes, water charges, sewer rents and assessments not yet due and payable, (d) variations between tax map and lines of record title, (e) any and all easements, servitudes, covenants, restrictions, agreements or other instruments recorded in the public records of El Paso County, Colorado as of the effective date hereof, (f) any and all rights or easements, if any, of any governmental unit or any public or private utility company, to maintain telephone wires, pipes, cable, conduits or other facilities that enter or cross the Property, (g) any other lien or encumbrance consented to by Purchaser or that are deemed to Permitted Exceptions under this Agreement are hereinafter collectively referred to as “Permitted Exceptions.” If Purchaser does not deliver the Termination Notice, Purchaser shall be deemed to have approved the Permitted Exceptions.

3.5 Service Contracts. From and after the date hereof to and including the Closing Date, Seller shall use commercially reasonable efforts to keep in force, without any material defaults, all Service Contracts (as defined herein).

Remedies

8.1 Purchaser’s Default. If Seller has complied with all of the covenants and conditions contained in this Agreement and is ready, willing and able to convey its interest in the Property in accordance with this Agreement, and Purchaser fails to consummate this Agreement and take title, then the parties hereto recognize and agree that the damages that Seller will sustain as a result thereof will be substantial, but difficult if not impossible to ascertain. Therefore, the parties agree that, in the event of Purchaser’s default, Seller shall, as its sole remedy, be entitled to retain the Deposit as liquidated damages, and not a penalty, and neither party shall have any further rights or obligations with respect to the other under this Agreement, except for the any obligations that expressly survive termination of this Agreement.

8.2 Seller’s Default. In the event that Purchaser has complied with all of the covenants and conditions contained herein and is ready, willing and able to take title to the Property in accordance with this Agreement, Purchaser may, as its sole and exclusive alternative remedies with respect to any default of Seller under this Agreement (i) terminate this Agreement by written notice to Seller, and receive (a) a

12

refund of the Deposit together with interest earned thereon and (b) solely in the event of Seller’s willful default, payment to Purchaser of all of its actual third party costs and expenses incurred in connection with this transaction, (ii) commence an action for specific performance or (iii) waive all claims on accounts of Seller’s default and proceed to Closing. Election of one of the aforesaid remedies shall preclude an election of others.

8.3 Notwithstanding any provision to the contrary contained in this Agreement or any documents executed by Seller pursuant hereto or in connection herewith, the maximum aggregate liability of Seller, and the maximum aggregate amount which may be awarded to and collected by Purchaser, under this Agreement and under any and all documents executed pursuant hereto or in connection herewith for which a claim is timely made by Purchaser shall not exceed Nine Hundred Thousand Dollars ($900,000) exclusive of any amounts required to be paid by Seller pursuant to Article VII. Further, the liability of Seller shall be limited to the assets of Seller, and in no event shall Purchaser seek satisfaction for any such liability from any of Seller’s parent company, members, affiliates and subsidiaries, and their respective members, stockholders, directors, officers, participants, employees, consultants, brokers and agents.

8.4 Notwithstanding anything herein to the contrary, in no event shall Purchaser or Seller be liable to the other party hereto for special, punitive or consequential damages.

Article IX

Loss due to Casualty or Condemnation

9.1 Loss due to Condemnation. In the event of a condemnation occurring after the Effective Date and prior to the Closing Date if all or a Substantial Portion of the Real Property is taken, either party may, upon written notice to the other party given within ten (10) days of receipt of notice of such event, cancel this Agreement, in which event Seller shall instruct the Escrow Agent to return the Deposit to Purchaser, this Agreement shall terminate and neither party shall have any rights or obligations hereunder except for the Surviving Obligations. In the event that neither party elects to terminate, or if the condemnation affects less than a Substantial Portion or does not affect the building or parking area, then this Agreement shall remain in full force and effect, and Seller shall be entitled to all monies received or collected by reason of such condemnation prior to closing. In such event, the transaction hereby contemplated shall close in accordance with the terms and conditions of this Agreement except that there will be an abatement of the Purchase Price equal to the amount of the net proceeds, less costs and attorney’s fees, which are received by Seller by reason of such condemnation prior to the Closing Date. If the condemnation proceeding shall not have been concluded prior to the Closing Date, then there shall be no abatement of the Purchase Price and Seller shall assign any interest it has in the pending award to Purchaser. For purposes of this Section 9.1, a “Substantial Portion” shall mean a condemnation of (i) any portion of the building or (ii) any portion of the parking lot which materially affects the number of parking spaces or ingress/egress from the parking lot.

9.2 Loss due to Casualty. In the event of Substantial Loss or Damage to the Improvements by fire or other casualty (not resulting from negligent act of Purchaser) which fire or casualty shall have occurred after the date of this Agreement, either party may, upon written notice to the other party given within ten (10) days of receipt of notice of such event, cancel this Agreement in which event Seller shall instruct the Escrow Agent to return the Deposit to Purchaser and this Agreement shall terminate and neither party shall have any rights or obligations hereunder except for the Surviving Obligations. In the event that neither party elects to terminate, or if the casualty results in less than Substantial Loss or Damage, then this Agreement shall remain in full force and effect and Seller shall be entitled to all insurance proceeds received or collected by reason of such damage or loss, whereupon the transaction hereby contemplated shall close in accordance with the terms and conditions of this Agreement except

13

that there will be an abatement of the Purchase Price equal to the amount of the net proceeds (including reductions for costs and attorney’s fees) which are received by Seller as a result of such damage or loss, provided that such abatement will be reduced by the amount expended by Seller in accordance with Article X hereof for restoration or preservation of the Property following the casualty. Alternatively, Purchaser may, in its discretion, have Seller repair or replace the damaged Property, and there shall be no abatement of the Purchase Price in such case. For purposes of this Section 9.2, “Substantial Loss or Damage” shall mean loss or damage, the cost for repair of which equals ten percent (10%) or more of the Purchase Price.

Article X

B. Seller shall not enter into any new Service Contracts or any other agreements that will be binding upon Purchaser after Closing, nor transfer any of the Premises or create any easements that would materially and adversely affect the Premises, without in each case first obtaining Purchaser’s prior written consent, which shall not be unreasonably withheld.

Each party represents and warrants to the other that, other than with respect to Broker, it has not made any agreement or taken any action which may cause any person to become

entitled to a commission or other compensation as a result of the transactions contemplated by this Agreement. Seller and Purchaser will each indemnify and defend the other from any and all Claims, actual or threatened, for any such fee, commission or other compensation by any third person other than Broker with whom such party has had dealings in connection with the transactions contemplated by this Agreement.
