Buyer represents and warrants to Seller as follows, except as set forth on a Disclosure Schedule delivered by Buyer concurrently with the execution and delivery of this Agreement (the "Buyer Schedule"): K. Organization. Buyer is a real estate investment trust duly formed and existing under and by virtue of the laws of the State of Maryland and is in good standing with the State Department of Assessments and Taxation of Maryland and has all requisite power and authority to own, lease and operate its properties and to carry on its business as now being conducted except where the failure to be so organized, existing and in good standing or to have such power and authority would not have a Buyer Material Adverse Effect. As used in this Agreement, "Buyer Material Adverse Effect" shall mean any fact, condition, event, development or occurrence which, individually or when taken together with all other such facts, conditions, events, developments or occurrences, has had or could reasonably be expected to have a material adverse effect on the ability of Buyer to consummate the transactions contemplated hereby. But in no case shall include the effects of facts, conditions, events, developments or occurrences that are generally applicable in (1) the commercial real estate industry, (ii) the United States economy or credit markets, or (iii) the United States securities markets. Buyer is duly qualified or licensed to do business and in good standing in each jurisdiction in which the property owned, leased or operated by it or the nature of the business conducted by it makes such qualification or licensing necessary, except where the failure to be so duly qualified or licensed and in good standing would not in the aggregate have a Buyer Material Adverse Effect. Buyer has heretofore made available to Seller a complete and correct copy of the Declaration of Trust and by-laws or comparable organizational documents, each as amended to date, of Buyer. Such Declaration of Trust, by-laws and comparable organizational documents are in full force and effect. Buyer is not in violation of any provision of its Declaration of Trust, partnership agreement, charter, by-laws or comparable organizational documents, except for such violations that would not, individually or in the aggregate, have a Buyer Material Adverse Effect. L. Consents and Approvals. The execution, delivery or performance of this Agreement by Buyer; the consummation by Buyer of the transactions contemplated hereby; and the compliance by Buyer with any of the provisions hereof will not (i) conflict with or result in any breach of any provision of the Declaration of Trust or Bylaws of Buyer, (ii) require any filing by Buyer or its Subsidiaries with, or permit, authorization, consent or approval of, any Governmental Entity to be obtained by Buyer (except where the failure to obtain such permits, authorizations, consents or approvals or to make such filings would not have a Buyer Material Adverse Effect), or (iii) violate any order, writ, injunction, decree, statute, ordinance, rule or regulation applicable to Buyer except, in the case of clause (iii), for violations, breaches or defaults which would not have a Buyer Material Adverse Effect. M. Litigation. There is no suit, claim, action, proceeding or investigation pending (in which service of process has been received by an employee of Buyer) or, to the knowledge of Buyer, threatened against Buyer before any Governmental Entity which, if adversely determined, individually or in the aggregate would have a Buyer Material Adverse Effect. Buyer is not subject to any outstanding order, writ, injunction or decree which, insofar as can be reasonably foreseen, individually or in the aggregate, in the future would have a Buyer Material Adverse Effect. N. Absence of Certain Changes or Events; Material Agreements. Since December 31, 1996, Buyer has conducted its business only in the ordinary and usual course consistent with past practice, and there has not been any change or development, or combination of changes or developments, which have a Buyer Material Adverse Effect. The transactions contemplated by this Agreement will not constitute a change of control under or require the consent from or the giving of notice to a third party pursuant to the terms, conditions or provisions of any Contract to which Buyer is a party or by which it is bound. O. No Violation of Law. To its knowledge, Buyer is not in violation of, or, under investigation with respect to, or been given notice or been charged by any Governmental Entity with any violation of, any law, statute, order, rule, regulation, ordinance or judgment (including, without limitation, any applicable environmental law, ordinance or regulation) of any Governmental Entity, except for violations which, in the aggregate, do not have a Buyer Material Adverse Effect. P. Brokers or Finders. Buyer does not have any liability to any agent, broker, investment banker, financial advisor or other firm or person for any broker's or finder's fee or any other commission or similar fee in connection with this Agreement or any of the transactions contemplated hereby.

Possession of the Premises is to be given to Buyer, subject to the right of tenants under the Leases on the Closing Date, by delivery of the Deed, and all keys, combinations and security codes at Closing. VII. BUYER'S REVIEW AND APPROVAL OF TITLE AND SURVEY. A. Title Binder. Buyer has secured a current title commitment (the "Title Binder") from the Title Company, and shall have until the Inspection Period Expiration Date (as hereinafter defined in Section VII.(C) to examine the condition of title, including the terms and provisions of all items and documents referred to in the Title Binder, and all information regarding title as disclosed on the Survey (hereinafter defined), and to approve or disapprove the same. If Buyer shall disapprove the condition of title, such disapproval shall be set forth in a notice given to Seller (the "Disapproval Notice") identifying the condition of title to the Property or any of the terms, provisions or contents of said items, documents or Survey which are disapproved by Buyer (the "Title Objections"). Subject to the provisions of the succeeding portion of this Section VII.A., Seller shall have until the date which is ten (10) days after the date of the Disapproval Notice (the "Title Cure Expiration Date") in which to cure or eliminate all items which Buyer disapproves in the Disapproval Notice, and to furnish evidence satisfactory to Buyer and the Title Company that all such items have been cured or eliminated or that arrangements have been made with the Title Company and any parties in interest to cure or eliminate the same at or prior to the Closing. If Seller fails to remove any Title Objection in accordance with the provisions of the immediately preceding sentence, Buyer, nevertheless, may elect (at or prior to the Closing) to consummate the transaction provided for in this Agreement subject to any such Title Objection(s) as may exist as of the Closing with a credit against the Purchase Price equal to the sum necessary to remove such Title Objection(s), and Seller shall remain liable (which liability shall survive the Closing) for the cost of removing any such Title Objection in excess of the credit granted against the cash portion of the Purchase Price, and Seller shall reimburse Buyer for any and all costs, claims, damages, obligations, liabilities and expenses (including, without limitation, reasonable legal fees and expenses) incurred by Buyer with respect to the Title Objection(s). If Buyer shall not so elect, Buyer may terminate this Agreement by notice in writing to Seller, whereupon the Deposit shall be immediately refunded to Buyer, and this Agreement shall be null and void, and the parties hereto shall be relieved of all further obligations and liability under this Agreement. B. Survey. Within five (5) business days after the date of this Agreement, Buyer shall order a current survey of Property (the "Survey"), prepared by a duly licensed land surveyor acceptable to Buyer. The Survey shall be currently dated, shall show the location on the Property of all buildings and improvements, building and set-back lines, easements, rights-of-way, encroachments, elevations between public roads providing access to the Property, and the boundary of the Property, and other such matters affecting the Property whether physically apparent from the ground, of record in public offices, or otherwise, and shall contain a legal description of the boundaries of the Premises by metes and bounds which shall include a reference to the recorded plat, if any. The surveyor shall certify to Buyer and to the Title Company and to any lender making a loan to Buyer secured by the Property that the Survey is correct and was made on the ground; and that there are no visible discrepancies, conflicts, encroachments, overlapping of improvements, violations of set-back lines, easements, rights-of-way or other such matters affecting the Property except as are shown on the Survey, and that the Survey conforms to all ACTA/ACSM and Pennsylvania Land Title Association standards and requirements for a Class A Survey. Any and all recorded matters shown on said Survey shall be legibly identified by appropriate volume and page recording references with dates of recording noted. Buyer shall have until the Inspection Period Expiration Date to approve or disapprove the material contained thereon. If Buyer shall disapprove such Survey, such disapproval shall be set forth in a Disapproval Notice as hereinabove provided in Section VII.A., and the provisions of Section VII.A. with respect to Disapproval Notices shall apply. C. Physical Inspection. For a period (the "Inspection Period") commencing on the second (2nd) business day next following the date upon which Buyer shall receive from Seller a fully-executed counterpart of this Agreement, and expiring twenty (20) days thereafter (such date is herein referred to as the "Inspection Period Expiration Date"), Buyer shall have the right to have performed a physical and mechanical inspection, measurement and audit of the Property, and Seller shall cooperate with Buyer and shall furnish to Buyer such information, materials and documents as Buyer may reasonably request. The inspection, audit and measurement of the Property's operation, condition and maintenance shall include, without limitation, such environmental and engineering inspections, reviews and assessments that Buyer deems appropriate. In the event Seller shall fail to deliver or make available any item or information material to Buyer's review of the Property and required to be delivered or made available pursuant to the terms of this Section within five (5) business days next following the date upon which Buyer shall receive from Seller a fully-executed counterpart of this Agreement, then at Buyer's election, the Inspection Period Expiration Date (and the Closing Date) shall be extended by one day for each day that the delivery or availability of such item is delayed. If Buyer, at Buyer's sole and absolute discretion, shall find such inspection(s) to be unsatisfactory for any reason whatsoever, Buyer shall have the right, at its option, to terminate this Agreement on or before the Inspection Period Expiration Date, and upon such termination, the Deposit shall be immediately refunded to the Buyer, and thereupon the parties hereto shall have no further liabilities one to the other with respect to the subject matter of this Agreement. Buyer agrees that it shall not unreasonably interfere with tenants in performing its inspection. Buyer further agrees that (i) all such activity shall be done in a good and workmanlike manner and the Property shall at all times be kept in a safe condition, (ii) immediately after each such survey, assessment or evaluation, Buyer shall restore to their prior condition those portions of the Premises disturbed or damaged by Buyer's activity, (iii) Buyer shall defend, indemnify and save Seller harmless from and against all claims, actions, suits, damages, losses, costs and expenses (including, without limitation, attorneys' fees) instituted against or incurred by Seller as a result of or relating to any activity on the Premises by Buyer, its agents, employees, designees, representatives and independent contractors, and (iv) if requested by Seller, Buyer shall provide Seller with a certificate of comprehensive general liability insurance, in form, in an amount and issued by a carrier reasonably acceptable to Seller, insuring Seller from all risks and loss associated with Buyer's exercise of its rights hereunder.

E. Notification of Certain Matters.

Minimal Damage. If prior to the Closing Date any portion of the Property is damaged or destroyed by fire or other casualty, and the cost of repair or restoration thereof shall be $50,000 or less (as established by good faith estimates obtained by Buyer), this Agreement shall remain in force. C. Substantial Damage. If prior to the Closing Date any portion of the Property is damaged or destroyed by fire or other casualty (a "Property Casualty") and if (i) the cost to repair the same as reasonably estimated by Seller and Buyer is less than $250,000, this Agreement shall not terminate as a result of the Property Casualty, Seller shall have no obligation to repair or restore the Property Casualty and Buyer shall receive at Closing a credit against the Purchase Price in the amount reasonably estimated by Seller and Buyer as the cost to fully repair and restore the Property Casualty. If a Property Casualty occurs prior to Closing and the cost to repair the same as reasonably estimated by Seller and Buyer is more than $250,000, or such damage results in the termination of the Lease with Penske Truck Leasing Co., LP, UGI Utilities, Inc., Gilbert/Commonwealth, Inc. or Parsons Power, Buyer may terminate this Agreement by giving notice to Seller within thirty (30) days after Buyer receives notice of the casualty, unless, prior to such date, Seller and Buyer shall have agreed (it being understood that neither the Seller nor Buyer shall have any obligation to so agree) to postpone the Closing Date for a period of time sufficient to permit Seller to fully repair and restore the Property Casualty prior to Closing. If there is any partial or total damage or destruction of any portion of the Property, as above set forth, and if Buyer elects not to terminate this Agreement, then all insurance proceeds paid or payable to Seller shall belong to Buyer and shall be paid over and assigned to Buyer at Closing, and Seller shall further execute all assignments and any other documents or other instruments as Buyer may reasonably request or as may be necessary to transfer all interest in all such proceeds to Buyer or to whomever Buyer shall direct. In the event that the Seller and Buyer are unable to agree on the amount required to repair or restore the Property Casualty, either Seller or Buyer may request that the amount to fully repair and restore the Property Casualty be conclusively determined by an insurance adjuster selected by Seller and Buyer jointly. D. Closing After Substantial Damage. So long as this Agreement shall remain in force under Sections IX.B. or IX.C., then either (a) (i) all proceeds of insurance collected prior to Closing, plus the amount of deductible under Seller's insurance policy, shall be adjusted subject to Buyer's approval and participation in any adjustment, and shall be credited to Buyer against the Purchase Price payable by Buyer at Closing, and (ii) all unpaid claims and rights in connection with losses shall be assigned to Buyer at Closing, or, (b) at Buyer's option, Seller shall (i) restore the Property by Closing to its condition immediately preceding the casualty, (ii) remain liable for any damages resulting from the failure to complete the repair by Closing, and (iii) include Buyer, and obtain Buyer's approval to, any adjustments made by Seller. E. Rent Insurance. All rental loss insurance and the proceeds thereof allocable to any period subsequent to Closing shall be paid or assigned to Buyer at Closing. X. CONDEMNATION. If, prior to the Closing Date, all or any portion of the Premises is taken by eminent domain or a notice of any eminent domain proceedings with respect to the Premises or any part thereof is received by Seller, then Seller shall within five (5) days thereafter give notice thereof to Buyer and Buyer shall have the option to (a) complete the purchase hereunder or (b) if such taking, in Buyer's sole and absolute discretion, adversely affects the Premises or its current economic viability, terminate this Agreement, in which event the Deposit shall be immediately refunded to Buyer, and this Agreement shall be null and void. Buyer shall deliver written notice of its election to Seller within ten (10) days after the date upon which the Buyer receives written notice of such eminent domain proceedings. If notice of condemnation is received by Buyer and it fails to deliver said written notice of its election within said time period, such failure shall constitute a waiver by Buyer of its right to terminate this Agreement. If this Agreement is not so terminated, Buyer shall be entitled to all awards or damages by reason of any exercise of the power of eminent domain or condemnation with respect to or for the taking of the Premises or any portion thereof, and until such time as closing has occurred, or this Agreement terminates. Any negotiation for, or agreement to, and all contests of any offers and awards relating to eminent domain proceedings shall be conducted with the joint approval and consent of Seller and Buyer. XI.

Seller shall pay for one-half of all applicable realty transfer taxes related to the execution, delivery and recording of the Deed, Bill of Sale, and other Closing Documents, and all related recording charges.

Real estate taxes applicable to the Property for the tax year in which Closing occurs, based on the respective tax years for which such taxes are assessed and on the most recent assessment of the Property and the then applicable tax rates. All real estate taxes, charges and assessments shall be pro rated on a per diem basis as of midnight of the day preceding the Closing Date, disregarding any discount or penalty and on the basis of the fiscal year of the authority levying the same. If any of the same have not been finally assessed as of the Closing Date for the current fiscal year of the taxing authority, then the same shall be adjusted at Closing based upon the most recently issued bills therefor, and shall be re-adjusted immediately when and if final bills are issued. If any portion of the Property is a net leased property wherein the tenant(s) have paid or will pay all such taxes, charges and assessments directly to the person or entity entitled to receive the same (and not to Seller as landlord under the applicable Leases), no apportionment shall be made. 2. Sewer Rents. All sewer rents not based on meter readings. Seller shall cause all utility meters to be read and the municipalities or utility companies servicing the Property to issue final bills to Seller as of the date of Closing, and all such bills shall be paid by Seller. 3.

All items of operating cost or expense incurred by Seller, including but not limited to utilities and fuel oil, and reasonably allocable or attributable to periods after Closing; 5. Rents. All rents collected, both Basic Rents (as hereinafter defined) and Additional Rents (as hereinafter defined) shall be deemed to be applied first to the calendar month in which Closing occurs and thereafter to current rental periods and secondly to satisfy rental obligations arising from past rental periods prior to the date of Closing. As used herein, the term "Basic Rents" shall mean all rents and charges payable by any and all tenants, including, without limitation, occupancy rents, but excluding Additional Rents. As used herein, the term "Additional Rents" shall mean any amounts payable by tenants pursuant to any provisions of such leases relating to escalation and pass-through of operating and other similar expenses and any provisions therein in respect of tenant escrows and reimbursements. Basic Rents shall be apportioned as follows: (a) Buyer shall receive a credit at Closing for all Basic Rents actually collected prior to Closing relating to any period after Closing; and (b) With respect to Basic Rents uncollected as of Closing and owed by occupants of the Property at Closing for any period prior to the calendar month in which Closing occurs, Seller shall be reimbursed by Buyer following Buyer's collection of such Basic Rents, to the extent they are available in accordance with the provisions hereof, as follows: Buyer shall use its best efforts to collect such rents, and all amounts collected by Buyer, net of related costs of collection, shall be paid to Seller within ten (10) days following the month of collection until the entire amount of such uncollected rents shall have been paid. If Buyer is unable to collect any portion of such Basic Rents within one hundred eighty (180) days following Closing, Buyer may elect, with respect to such Basic Rents, either to (I) assign all such Basic Rents to Seller, after which Seller may pursue any remedies to collect such Basic Rents and retain any amounts so collected, or (II) retain such Basic Rents, in which event Buyer, within one hundred eighty (180) days following Closing, shall make a cash payment to Seller of the amount of such Basic Rents, less Buyer's reasonable expenses relating to efforts to collect such Basic Rents, after which any amounts collected by Buyer shall be retained by Buyer. Additional Rents shall be apportioned as follows: (a) With respect to Additional Rents uncollected at Closing and owed for any period prior to Closing and not yet billed, Buyer shall submit appropriate bills to the tenants as soon as is practicable after Buyer receives sufficient information from Seller concerning Additional Rents to enable Buyer to do so. Buyer shall use its best efforts to collect such Additional Rents for a period of three hundred sixty-five (365) days after the rentals become due. Seller's apportioned interest in any amounts collected by Buyer to the extent such amounts are available in accordance with the provisions hereof, net of the costs of collection, shall be paid to Seller within ten (10) days following receipt thereof. If after the applicable three hundred sixty-five (365) day period Buyer has been unable to collect any Additional Rents, Buyer may elect, with respect to one or more of the leases one of the two alternatives set forth under subsection (A)(2) above, with the same related cash payment or assignment of accounts as is therein provided; (b) With respect to Additional Rents billed and owed by occupants of the Property as of Closing, Buyer shall use its best efforts to collect such Additional Rents for a period of one hundred eighty (180) days after Closing. Any such amounts collected by Buyer, to the extent available pursuant to the provisions hereof, net of the costs of collection, shall be paid to Seller within ten (10) days following receipt thereof. If after the applicable one hundred eighty (180) day period Buyer has been unable to collect Additional Rents, Buyer may elect, with respect to any one or more of the leases one of the two alternatives set forth under subsection (A)(2) above, with the same related cash payment or assignment of accounts as is therein provided; (c) Additional Rents shall be allocated over the period with regard to which such operating expenses are incurred, notwithstanding the date on which such Additional Rents become payable; and (d) If the Premises are entirely net leased and the tenant(s) pay all Additional Rent directly to third parties, no apportionments or adjustments shall be made. 6. Security Deposits. Seller shall deliver to Buyer at Closing, in cash or by certified check without adjustment, the amounts of all security deposits which may have been received from tenants, together with interest thereon which is due to any tenant under the provisions of any Lease or applicable law. 7. Project Contracts. The unpaid monetary obligations of Seller under all Contracts shall, as a general matter, be pro rated on a per diem basis as of midnight of the day preceding the Closing Date, subject, nevertheless, to the following: With respect to all leasing, brokerage or other commission agreements relating to Property Leases, there shall be no apportionment or reimbursement of or for any leasing fees, commissions or other compensation ("Leasing Fees") which is in respect of any lease executed prior to the Closing, all of which shall be and remain the responsibility of Seller, and Seller shall pay the same when due and shall indemnify and hold Seller harmless from all thereof; and (ii) provided Closing occurs hereunder, Buyer shall be responsible for and shall pay when due and indemnify and hold Seller harmless from and against or reimburse to Seller if Seller has paid any Leasing Fees with respect thereto, all Leasing Fees which are due and payable subsequent to Closing on an "as collected" basis or all Leasing Fees which are due and payable for a renewal term which shall come into effect on or after the Closing Date; provided, however, Seller shall have disclosed to Buyer the existence of such Leasing Fee on the Company Schedule. Leasing Fees apportionable hereunder shall be apportioned and pro rated on a per diem basis as of midnight of the day preceding the Closing Date and as a function of (and calculated with respect to) the lease term for which the same were paid or will become due and payable. B. Custom and Practice. Except as set forth in this Agreement, the customs of the State and County in which the Premises are located shall govern prorations. C. Future Installments of Taxes. If at Closing, the Property or any part thereof shall be or shall have been affected by an assessment or assessments which are or may become payable in installments, then for purposes of this Agreement, all unpaid installments of any such assessment, including those which are to become due and payable and to be liens upon the Property shall be paid and discharged by Seller at Closing. D. Application of Prorations. If such prorations result in a payment due Buyer, the cash payable at Closing shall be reduced by such sum. If such prorations result in a payment due Seller, the same shall be paid by uncertified check at Closing. E. Schedule of Prorations. The parties shall endeavor to jointly prepare a schedule of prorations for the Property no less than five (5) days prior to Closing. F. Escalations. At least five (5) days prior to Closing, Seller shall deliver to Buyer a reasonably detailed statement setting forth, as of the date of Closing (a) the sums collected from tenants under Leases on account of or in reimbursement of landlord's operating expenses and/or any other payments made by tenants to landlord on account of sums which are attributable to expenses paid or incurred by the landlord ("escalation payments") for the current fiscal year under each such Lease (whether a lease year or calendar or other year); and (b) the amounts paid or incurred by Seller during the appropriate fiscal year as aforesaid which Seller expects will be paid or reimbursed by escalation payments made by tenants. If Seller shall have collected escalation payments for periods prior to Closing, whether pursuant to estimates which were in excess of the amounts actually required to be paid, or otherwise, there shall be an adjustment and credit to Buyer at Closing for such excess. If the charges were not billed or have not been collected as of the date of Closing, then, when the amount of such escalation payments is determined and collected by Buyer from tenants, Buyer will, upon collection, remit to Seller the portion thereof to which Seller is entitled to the date of Closing. Buyer shall have the right, in good faith, to settle or adjust any amount of such escalation payments due from any tenant without Seller's prior consent, provided that such settlement or adjustment applies ratably to all amounts of escalation payments due from such tenant. G. Readjustments. The parties shall correct any errors in prorations as soon after the Closing as amounts are finally determined. H. Indemnification for Seller's Tax Obligations. Seller shall indemnify, defend and save and hold harmless Buyer from any loss, cost, liability or expense (including, without limitation, reasonable counsel fees and court costs) incurred, paid or suffered by Buyer arising out of or by reason of any claim made by the Pennsylvania Department of Revenue or by any other state taxing or employment authorities asserting or indicating any claims or possible claims for unpaid taxes, penalties, interest or court costs related thereto of Seller or any related party, due the Commonwealth of Pennsylvania or its political subdivisions.

Such notice shall set forth the basis for objection to the delivery of the Deposit. Upon receipt of such notice, the Escrow Agent shall promptly deliver a copy thereof to the party who filed the written demand. C. Escrow Subject to Dispute.

Promptly after receiving such notice, Seller will, upon notice to Buyer, have the right to assume and control the defense and settlement of any such Third Party Action at its own cost and expense; provided, however, that it shall be a condition precedent to the exercise of such right by Seller that Seller shall agree in writing that the Loss, or Third Party Action, as the case may be, is properly within the scope of the indemnification obligation and that as between the parties, Seller shall be responsible to satisfy and discharge such Third Party Action. Seller shall not enter into any resolution or other compromise of a Third Party Action without obtaining the complete release of Buyer for any liability to all claimants under or pursuant to such Third Party Action. Buyer shall have the right to participate in any such defense, contest or other protective action at its own cost and expense. Notwithstanding the foregoing, Buyer shall have the right to assume and control the defense and settlement of a Third Party Action (a) if such action includes claims for equitable relief which, if determined adversely to Buyer, could reasonably be expected to interfere with its intended business operations or damage its business reputation or (b) if Seller fails to do so in a timely manner. In any circumstances in which Buyer undertakes to control the Third Party Action as provided in this paragraph, it shall (i) not enter into any resolution or other compromise involving monetary damages without obtaining the prior written consent of Seller provided that such written consent may not be withheld if it would interfere with Buyer's business operation and (ii) keep Seller informed on an ongoing basis of the status of such Third Party Action and shall deliver to Seller, copies of all documents related to the Third Party Action reasonably requested by Seller. Buyer shall act to assure that all attorneys' fees and expenses incurred in connection therewith are reasonable. XXI. EXCULPATION. No recourse shall be had for any obligation of Buyer under this Agreement or under any document executed in connection herewith or pursuant hereto, or for any claim based thereon or otherwise in respect thereof, against any past, present or future trustee, shareholder, officer or employee of Buyer, whether by virtue of any statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being expressly waived and released by the Seller and all parties claiming by, through or under Seller. IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed the day and year first above written. SALIENT 3 COMMUNICATIONS, INC.
