ENVIRONMENTAL INSPECTION PERIOD. 5.1 PHASE I STUDY. From the Contract Date to March 2, 2001 (the "ENVIRONMENTAL INSPECTION PERIOD"), Buyer and its employees, agents, and third party consultants (collectively, the "BUYER'S REPRESENTATIVES") shall be entitled to enter on the Land and Improvements, at reasonable times and on reasonable notice to Seller, to perform a phase I environmental study of the Land (the "PHASE I STUDY"). Buyer shall provide not less than twenty-four (24) hours' prior telephonic notice to Seller before performing any such study. 5.2 PHASE II STUDY. If the Phase I Study discloses a "recognized environmental condition" (as that phrase is defined in ASTM E1527-00 Standard Practice for Environmental Site Assessments: Phase 1 Environmental Site Assessment Process; the "ASTM STANDARDS"), then Buyer at its sole election may extend the Environmental Inspection Period for a period not to exceed sixty (60) days to enable Buyer to perform a Phase II environmental study within the meaning of the ASTM Standards (the "PHASE II STUDY"; the Phase I Study and the Phase II Study, if any, are hereinafter collectively referred to as the "ENVIRONMENTAL STUDIES"). Buyer shall make such election by notifying Seller and Escrow Agent in writing before the expiration of the Environmental Inspection Period. Buyer shall perform the Environmental Studies as soon as possible using commercially reasonable efforts. If the Environmental Studies reveal environmental conditions that are unacceptable to Buyer in the exercise of its commercially reasonable judgment, Buyer may terminate this Contract before the last day of the Environmental Inspection Period (as it may have been extended as provided in this Section 5.2) (the "APPROVAL DATE") by notifying Seller and Escrow Agent in writing (the "TERMINATION NOTICE"). On receipt of the Termination Notice, Buyer shall as a condition to the return of the Deposit, deliver to Seller true, correct, and complete copies of the Environmental Studies. On receipt of the Termination Notice by Seller and Escrow Agent, Escrow Agent shall return the Deposit to Buyer and neither party shall have any further liabilities or obligations except for those liabilities and obligations that expressly survive a termination of this Contract. If Buyer fails timely to deliver a Termination Notice to Seller and the Escrow Agent before the end of the Environmental Inspection Period (as extended, if applicable), Buyer shall be automatically deemed to have forever waived its right to terminate this Contract and receive a refund of the Deposit (except as otherwise expressly provided herein) and the Property shall be deemed acceptable to Buyer. 5.3 BUYER'S UNDERTAKING. Buyer hereby covenants and agrees that it shall cause the Environmental Studies to be performed in a manner that does not unreasonably disturb or disrupt the business operations of Seller. If Buyer performs a Phase II Study (which may include physically intrusive investigations of the Land and Improvements, such as sampling of soils and other media), Buyer shall provide a written scope of work to Seller describing in reasonable detail the procedures Buyer desires to perform and request Seller's express written consent to the Phase II Study, which consent shall not be unreasonably withheld, delayed, or conditioned. Buyer and Buyer's Representatives shall, in performing the Environmental Studies, comply with the agreed on procedures and with any and all Laws (as defined below) applicable to such procedures or to the Land and Improvements, or both. Neither Buyer nor Buyer's Representatives shall report the results of the Environmental Studies to any Governmental Authority (as defined below) under any circumstances without first obtaining Seller's express 3 <PAGE> written consent, which consent may be withheld in Seller's sole and absolute subjective discretion; PROVIDED, HOWEVER, that if the results of the Environmental Studies are required to be reported by any Law, Seller shall promptly report such results to the extent so required. If Seller fails to do so, Buyer may report such results to the appropriate Governmental Authority if such failure to report would expose Buyer to legal liability. For purposes of this Contract, "LAW" means all applicable laws, ordinances, rules, and regulations, codes, licenses, permits, orders, approvals, plans, authorizations, and similar items of any applicable federal, state, municipal, or other governmental or quasi-governmental department, commission, board, bureau, agency, or instrumentality (collectively, the "GOVERNMENTAL AUTHORITY"). 5.4 REPORTS; INSURANCE; RESTORATION.

Buyer hereby indemnifies, protects, defends (with counsel reasonably acceptable to Seller), and holds Seller, Seller's affiliates, their respective shareholders, officers, and directors, and all of their respective successors and assigns (collectively, the "SELLER INDEMNIFIED PARTIES"), harmless from and against any and all losses, damages, claims, causes of action, judgments, damages, costs, and expenses (including, but not limited to, court costs and reasonable attorneys' fees) (collectively, "LOSSES") to the extent that any Seller Indemnified Party suffers or incurs as a result of, or in connection with, (a) any damage caused to, in, or at the Property; (b) injury or death to person; or (c) mechanic's liens or materialmen's liens arising out of, or in connection with, the Environmental Studies, or Buyer's or Buyer's Representatives entry on the Land and the Improvements hereunder; PROVIDED, HOWEVER, that Buyer shall not be obligated to indemnify and hold Seller Indemnified Parties harmless from Losses to the extent that the Losses (i) result from Seller's sole negligence or intentional misconduct, or (ii) involve damage to the Property and Closing occurs under this Contract. Buyer's undertakings pursuant to this Section 5 shall survive Closing for a period that shall end on the sixtieth (60th) day after the third (3rd) anniversary of the Closing Date, unless a specific claim in writing with respect to such matters shall have been made by Seller prior thereto. Seller shall promptly notify Buyer of any claim relating to any such Losses. 4 <PAGE> 5.6 PROPRIETARY INFORMATION. Buyer acknowledges that Seller's business operations involve the use of highly sensitive, confidential, and proprietary information (the "PROPRIETARY INFORMATION"), and that it is imperative that Buyer and Buyer's Representatives be accompanied by an authorized agent of Seller during any entry into the Buildings by Buyer and Buyer's Representatives. Because of the sensitive nature of Seller's business operations, it may not be possible to provide ready access to Buyer and Buyer's Representatives to every part of the Buildings at any given time. For purposes of this Contract, Proprietary Information includes (a) all information or material of Seller that is proprietary because it has a significant business purpose and is unique to the business and operations of Seller, including, but not limited to, methods, strategies, software, technology, computer programs, customer and prospect lists, supplier lists, records, product design or development, financial information, budgets, marketing plans, pricing information and strategies, cost data, salary information, market information, personnel, trade secrets, and other business information; (b) inventions, discoveries, concepts, technical information, processes, formulas, specifications and know-how conceived, obtained, or developed in whole or in part by Seller or its employees or agents, or created, in whole or in part, with Seller's equipment, supplies, personal property, or facilities; and (c) information and materials received by Seller from third parties in confidence (i.e., subject to non-disclosure or similar covenants). 5.7 CONFIDENTIALITY.

Buyer shall maintain in strict confidence the Environmental Studies. Each party shall not under any circumstances disclose all or any portion of the Transaction Information (and Buyer shall not disclose the Environmental Studies) to any person or entity and shall maintain the Transaction Information (and Buyer shall maintain the Environmental Studies) in the strictest confidence as confidential information; PROVIDED, HOWEVER, that either party may disclose the Transaction Information (and Buyer may disclose the Environmental Studies) (a) to such party's agents, employees, attorneys, lenders, underwriters, consultants, and accountants to the extent that such parties reasonably need to know such information and data to assist, and perform services on behalf of, Buyer or Seller, as the case may be; (b) to the extent required by any applicable Law (except as provided in Section 5.3 above); and (c) in connection with any litigation that may arise between the parties in connection with the transactions contemplated by this Contract. Buyer shall advise Buyer's Representatives of the provisions of this Section 5.7 and cause such parties to maintain the Transaction Information and the Environmental Studies as confidential information and to comply with the terms of this Section 5.7. Buyer agrees that the Environmental Studies and any Proprietary Information obtained in conducting the Environmental Studies shall be used solely for purposes of evaluating the acquisition of the Property from Seller. Notwithstanding anything contained herein to the contrary, it is understood and agreed that money damages would not be a sufficient remedy for any breach of this Section 5.7 by Buyer or Buyer's Representatives and that Seller shall be entitled to specific performance and injunctive or other equitable relief as a remedy for any such breach of this Section 5.7 by Buyer or Buyer's Representatives, and Buyer further agrees to waive any requirement for the security or posting of any bond in connection with such remedy. Such remedy shall not be deemed to be the exclusive remedy for a breach of this Section 5.7 but shall be in addition to all other remedies available at law or equity to Seller. Buyer hereby 5 <PAGE> indemnifies, protects, defends, and holds Seller Indemnified Parties harmless from and against any and all Losses to the extent suffered or incurred by any Seller Indemnified Parties as a result of, or in connection with, (A) any disclosure of the Transaction Information or the Environmental Studies by Buyer or Buyer's Representatives other than in accordance with this Section 5.7, or (B) any other breach of this Section 5.7 by Buyer or Buyer's Representatives. The undertakings of Buyer pursuant to this Section 5.7 (y) with respect to the Proprietary Information shall indefinitely survive the Closing or termination of this Contract and shall not be merged into any instrument of conveyance delivered at Closing, and (z) with respect to Transaction Information other than the Proprietary Information, shall terminate at Closing and shall be merged into any instrument of conveyance delivered at Closing.

THE TERMS AND CONDITIONS OF THIS SECTION 10 WILL EXPRESSLY SURVIVE THE CLOSING AND 13 <PAGE> WILL NOT MERGE WITH THE PROVISIONS OF ANY CLOSING DOCUMENTS, INCLUDING, BUT NOT LIMITED TO, THE DEED. 11. SELLER'S CLOSING DELIVERIES. At Closing (or such other times as may be specified below), Seller shall deliver or cause to be delivered to Buyer the following: 11.1 DEED. A Deed, executed by Seller, for the Property conveying the Land and Improvements to Buyer, subject to the Permitted Exceptions. Seller, however, shall have no obligation to execute and deliver to Buyer, the Title Company, or any other entity or person an affidavit of title, owner's affidavit, or similar instrument. 11.2 LEASE. Two (2) duly executed counterparts of a lease agreement ("LEASE") between Buyer, as landlord, and Seller, as tenant, substantially in the form attached hereto as EXHIBIT G. During the Document Finalization Period, Seller and Buyer shall use their reasonable and good faith efforts to finalize the terms and conditions of the Lease, it being acknowledged and agreed that certain terms and conditions of the Lease remain subject to negotiation. On the finalization of the terms and conditions of the Lease, such final form shall be substituted in place of the form of Lease attached hereto as a part hereof as EXHIBIT G and the parties shall identify the final form of Lease by initialing it. If Seller and Buyer are unable to agree, despite the exercise of their reasonable and good faith efforts, on the final terms and conditions of the Lease by the end of the Document Finalization Period, the Escrow Agent shall return the Deposit to Buyer, this Contract shall terminate, and neither Seller nor Buyer shall have any further liabilities or obligations except for those liabilities and obligations that expressly survive a termination of this Contract. For purposes of this Contract, the Lease may ultimately be in the form of a sublease between Seller, as subtenant, and Buyer, as sublandlord, and, if so, (a) Buyer shall obtain the prior written consent of the fee owner of the Property to the sublease, and (b) Seller and Buyer shall modify the Lease so that it is in the form of a sublease. 11.3 ASSIGNMENT OF CONTRACTS. Two (2) duly executed counterparts of an Assignment and Assumption of Contracts and Intangibles (an "ASSIGNMENT OF CONTRACTS") for the Property in the form attached hereto as EXHIBIT E. The effective date of the Assignment of Contracts shall be Monday, October 1, 2001. Between the Closing Date and September 30, 2001, Seller shall have the right to enter into any new contract with respect to the ownership and operation of the Property that will have an expiration date after September 30, 2001, or that would otherwise affect the use, operation, or enjoyment of the Property after September 30, 2001, as long as the new contract is terminable on no more than thirty (30) days' prior written notice without penalty or termination fee to Buyer (any such new contract shall be deemed a "Contract" for purposes of this Contract). Buyer shall have the right to approve any such new contract, which approval shall not be unreasonably withheld, delayed, or conditioned. If Buyer does not approve or disapprove such new contract within five (5) Business Days after written request to do so, Buyer shall be deemed to have approved such new contract. If Seller enters into a new contract that is not terminable on no more than thirty (30) days' prior written notice or contains a penalty or termination fee, or both, and Buyer does not timely object to such new contract, Seller shall indemnify, protect, and defend and hold Buyer harmless from and against all losses, claims, costs, expenses, and damages (including, but not limited to, reasonable attorneys' fees) incurred by Buyer in connection with such undisclosed new contract. The 14 <PAGE> provisions of this Section 11.3 shall survive the Closing and shall not be merged into any instrument of conveyance delivered at Closing. 11.4 BILL OF SALE.

Corporate resolutions of Buyer authorizing Buyer to enter into this Contract and perform its obligations hereunder. Such resolutions shall contain, among other things, a statement indicating that Buyer has ascribed a value of at least Nine Million Dollars ($9,000,000) to the Administration Building. 12.7 OTHER DOCUMENTS. Such other documents as may be reasonably agreed on between Buyer and Seller for purposes of consummating the transactions contemplated by this Contract. 15 <PAGE> 13. PAYMENT OF PURCHASE PRICE; PRORATIONS AND ADJUSTMENTS. Provided all conditions precedent to Seller's obligations hereunder have been satisfied, Seller shall convey title to the Property to Buyer on confirmation of receipt of the Purchase Price by the Escrow Agent as set forth below. Buyer shall pay the balance of the Purchase Price, as adjusted by the prorations and expenses to be paid by Seller hereunder, to Escrow Agent by making a wire transfer of immediately available federal funds to the account of Escrow Agent no later than 11:00 a.m. Eastern Time on the Closing Date and unconditionally directing Escrow Agent to deposit the same (and Escrow Agent shall in fact initiate the transfer by such time) in Seller's designated account by 2:00 p.m. Eastern Time on the Closing Date. For each full or partial day after the Closing Date that Escrow Agent has not received in its account the payment specified in this Contract, Buyer shall pay to Seller one (1) day's interest on the unpaid funds at the rate PER ANNUM equal to the "prime rate" as announced from time to time by THE WALL STREET JOURNAL. The following items shall be prorated and adjusted between Seller and Buyer: 13.1 UTILITIES. Water, electricity, sewer, natural gas, telephone, and other utility charges based, to the extent practicable, on final meter readings and final invoices. Such expenses shall be prorated between Buyer and Seller, with Seller receiving a credit for any expenses paid by Seller and related to the period from and after Closing. 13.2 EXISTING CONTRACTS. Amounts paid or payable under the Contracts shall be prorated. 13.3 ASSESSMENTS. All assessments, general or special, shall be prorated as of the Closing Date, with Seller being responsible for any installments of assessments that are due before the Closing Date and Buyer being responsible for any installments of assessments that are due on or after the Closing Date. 13.4 TAXES. All ad valorem real estate and personal property taxes for the Property shall be prorated as of the Closing Date on a cash basis for the tax year in which the Closing occurs, regardless of the year for which such taxes are assessed. Buyer shall pay all sales tax payable in connection with the Personal Property, which sales tax shall be collected by Seller and thereafter paid over to the State of Maryland within the time required by law. 13.5 OTHER. Such other items that are customarily prorated in transactions of this nature shall be ratably prorated. 13.6 ADJUSTMENTS. If any prorations made pursuant hereto shall prove incorrect for any reason, or if the prorations set forth above are estimated on the most currently available (rather than based on the actual final) bills, either party shall be entitled to an adjustment to correct the same provided that it makes written demand on the other by no later than the first anniversary of the Closing Date. The provisions of this Section 13 shall survive Closing. 14. CLOSING EXPENSES. Seller shall only pay for: one-half (1/2) of any applicable recordation and transfer taxes and one-half (1/2) of the cost of any escrows hereunder. Buyer shall pay for one-half (1/2) of any escrow costs hereunder, one-half (1/2) of any applicable recordation and transfer tax, the cost of recording the Deed, the basic premium for the Title 16 <PAGE> Policy, the cost of "extended form coverage" and any endorsements to the Title Policy, the cost of any survey, and any recordation tax on the recordation of any instrument evidencing or securing any financing obtained by Buyer for all or any portion of the Property. Each party shall pay the costs of its respective consultants, attorneys, accountants, and other professionals. 15. DESTRUCTION, LOSS OR DIMINUTION OF PROPERTY. If, before Closing, all or any portion of the Property is damaged by fire or other natural casualty (collectively "DAMAGE"), or is taken or made subject to condemnation, eminent domain, or other governmental acquisition proceedings (collectively "EMINENT DOMAIN"), then: 15.1 GENERAL. If the aggregate cost of repair or replacement or the value of the Eminent Domain (collectively, "REPAIR AND/OR REPLACEMENT") is Three Million Dollars ($3,000,000) or less, in the opinion of Buyer's and Seller's respective engineering consultants, Buyer shall close and take the Property as diminished by such events with an assignment by Seller of any casualty insurance proceeds (together with a credit from Seller to Buyer of the full amount of any deductible not paid directly by Seller) or condemnation proceeds and the payment by Seller to Buyer of any applicable deductible amounts, less any amounts reasonably incurred by Seller to repair the Property and collect the insurance proceeds or condemnation award. 15.2 MATERIAL DAMAGE. If the aggregate cost of repair and/or replacement is greater than Three Million Dollars ($3,000,000), in the opinion of Buyer's and Seller's respective engineering consultants, then Buyer, at its sole option, may elect either to (a) terminate this Contract by written notice to Seller and the Escrow Agent, in which event the Deposit shall be returned to Buyer and neither party shall have any further liability to the other hereunder, except for those liabilities that expressly survive a termination of this Contract; or (b) proceed to close and take the Property as diminished by such events, together with an assignment of the proceeds of Seller's casualty insurance (together with a credit from Seller to Buyer of the full amount of any deductible not paid directly by Seller) for all Damage (or condemnation awards for any Eminent Domain) and the payment by Seller to Buyer of any applicable deductible amounts, less any amounts reasonably incurred by Seller to repair the Property and collect the insurance proceeds or condemnation award. 15.3 DISPUTES. If a dispute arises between Seller and Buyer with respect to the cost of repair and/or replacement for the matters set forth in this Section, an engineer designated by Seller and an engineer designated by Buyer shall select an independent engineer licensed to practice in Maryland who shall resolve such dispute. All fees, costs, and expenses of such third engineer so selected shall be shared equally by Buyer and Seller. 16. DEFAULT. 16.1 DEFAULT BY SELLER. In addition to the provisions of Section 18 (Litigation), if Seller shall be in material default hereunder any of the covenants and agreements of Seller hereunder, or in the event of a material breach by Seller of any Seller Representation when made that is not cured by Seller (in Seller's sole and absolute subjective discretion) on or before Closing, Buyer may either (a) terminate Buyer's obligations under this Contract by written notice to Seller and the Escrow Agent, in which event (i) the Deposit shall be returned to Buyer, and 17 <PAGE> (ii) on Buyer's receipt of the Deposit, this Contract shall terminate and neither party shall have any further liability hereunder except for those liabilities that expressly survive a termination of this Contract; or (b) Buyer may file an action for specific performance, provided that no such action in specific performance shall seek to require Seller to do any of the following: (i) change the condition of the Property or restore the same after any fire or other casualty; (ii) expend money or post a bond to remove a title encumbrance or defect or correct any matter shown on a Survey of the Property that Seller has not agreed to remove or correct pursuant to the provisions of this Contract; (iii) secure any permit, approval, or consent for the Property or Seller's conveyance of the Property where the failure to secure any such permit, approval, or consent would not constitute a breach of any representation or warranty of Seller under the provisions of this Contract; or (iv) vacate the Property in advance of the applicable expiration date for the space in question under the Lease. If Buyer prevails on the suit for specific enforcement in a court of competent jurisdiction, the Lease shall be of no force or effect and Seller shall have no right to lease the Property on the terms and conditions set forth in the Lease. Buyer shall have no other remedy for any default by Seller. In the event of the failure of any condition precedent to Buyer's obligation to close expressly herein set forth, Buyer's sole remedy hereunder, at law or in equity, shall be to terminate this Contract, in which event the Escrow Agent shall return the Deposit to Buyer, whereupon neither party shall have any further liability hereunder except for those liabilities that expressly survive a termination of this Contract. If, as a direct result of an intentional act of Seller taken with the intention of frustrating Closing or the willful misconduct of Seller, Seller is in breach or default of its obligations hereunder, and Buyer elects to terminate this Contract under clause (a) above on account of such breach or default, then, on such termination by Buyer hereunder, in addition to receiving the immediate return of the Deposit, Buyer shall also be entitled to receive from Seller, Buyer's documented out-of-pocket costs and expenses (including, but not limited to, reasonable attorney's fees) actually incurred by Buyer to conduct the Environmental Studies, to negotiate this Contract, and for acquisition and financing commitment and/or finder's fees (such costs, "TRANSACTION COSTS"). Buyer covenants and agrees that any Transaction Costs for which Buyer seeks payment under this Section 16.1 are based on commercially reasonable terms and conditions negotiated with unrelated third parties. Seller's maximum reimbursement liability for the Transaction Costs shall not exceed an amount equal to Two Million Five Hundred Thousand Dollars ($2,500,000). Buyer shall have the right to waive any condition precedent to its obligation to proceed to Closing, in which event the parties shall proceed to Closing without a reduction in the Purchase Price. 16.2 DEFAULT BY BUYER. If Buyer defaults in its obligations to close the purchase of the Property, or if Buyer otherwise materially defaults hereunder, then (a) Seller shall be entitled to receive the Deposit, together with all interest earned thereon, as fixed and liquidated damages, this Contract shall terminate and neither party shall have any further liability hereunder, except for those liabilities which expressly survive the termination of this Contract, and (b) Buyer shall immediately direct the Escrow Agent, in writing, to pay the Deposit to Seller. Seller shall have no other remedy for any default by Buyer, including any right to damages. BUYER AND SELLER ACKNOWLEDGE AND AGREE THAT (I) THE AMOUNT OF THE DEPOSIT 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 HAVE OCCURRED DUE TO A 18 <PAGE> DEFAULT OF BUYER UNDER THIS CONTRACT; (II) THE ACTUAL DAMAGES SUFFERED AND COSTS INCURRED BY SELLER AS A RESULT OF SUCH WITHDRAWAL AND FAILURE TO CLOSE DUE TO A DEFAULT OF BUYER UNDER THIS CONTRACT WOULD BE EXTREMELY DIFFICULT AND IMPRACTICAL TO DETERMINE; (III) BUYER SEEKS TO LIMIT ITS LIABILITY UNDER THIS CONTRACT TO THE AMOUNT OF THE DEPOSIT IF THIS CONTRACT IS TERMINATED AND THE TRANSACTION CONTEMPLATED BY THIS CONTRACT DOES NOT CLOSE DUE TO A DEFAULT OF BUYER UNDER THIS CONTRACT; AND (IV) THE AMOUNT OF THE DEPOSIT SHALL BE AND CONSTITUTE VALID LIQUIDATED DAMAGES AND NOT A PENALTY. All of the foregoing shall be without limitation on the rights and remedies of Seller hereunder, at law or in equity in the event of a default by Buyer pursuant to Sections 5.5 (Indemnification), 5.7 (Confidentiality), 18 (Litigation), or 21 (Brokerage), or any covenant, agreement, indemnity, representation or warranty of Buyer that survives the Closing or the termination of this Contract. 17. SUCCESSORS AND ASSIGNS. Buyer may not assign its rights under this Contract without the prior written approval of Seller, which approval Seller may grant or withhold in its sole and absolute subjective discretion; PROVIDED, HOWEVER, that Buyer shall have the right to assign its rights under this Contract to an entity that will permit or facilitate off-balance sheet financing of the Property for Buyer. In case of such permitted assignment, (a) Buyer shall notify Seller and Escrow Agent in writing of the identity of the assignee at least two (2) Business Days before the date of assignment and any other information relating to such entity as Seller may reasonably request, (b) between the Contract Date and the Closing Date, Buyer shall not be released from any liability or obligations under this Contract on any such assignment, it being understood and agreed that Buyer shall remain responsible for its obligations under this Contract if Buyer so assigns this Contract, (c) after the Closing Date, Buyer shall not be released from any liability or obligations under Sections 5 (Environmental Inspection Period), 18 (Litigation), 21 (Brokerage), and 22.10.2 (Indemnification) of this Contract on any such assignment, it being understood and agreed that Buyer shall remain responsible for its obligations under those provisions of this Contract if Buyer so assigns this Contract, and (d) the only entity that will occupy a portion of the Property while Seller is the tenant under the Lease will be Buyer or an affiliate of Buyer. 18. LITIGATION. In the event of litigation between the parties with respect to the Property, this Contract, the performance of their respective obligations hereunder or the effect of a termination under this Contract, the losing party shall pay all costs and expenses incurred by the prevailing party in connection with such litigation, including, but not limited to, reasonable attorneys' fees of counsel selected by the prevailing party. Notwithstanding any provision of this Contract to the contrary, the obligations of the parties under this Section 18 shall survive termination of this Contract. 19. NOTICES.
