(b) Name. The name of the Surviving Entity shall be “W&M Business Trust”.

(c) Certificate of Trust and Declaration of Trust.

3.02. Effective Date and Effective Time; Closing.

(a) The closing of the Transaction (the “Closing”) shall take place immediately prior to the Effective Time at 10:00 a.m., Eastern Time, at the offices of DLA Piper US LLP at 6225 Smith Avenue, Baltimore, Maryland 21209, or at such other place, at such other time, or on such other date as the parties may mutually agree upon (such date, the “Closing Date”).

ARTICLE IV.
MERGER CONSIDERATION; EXCHANGE PROCEDURES

4.01. Conversion of Shares.

At the Effective Time, by virtue of the Merger and without any action on the part of a holder of shares of Target Common Stock:

(a) The aggregate merger consideration payable to holders of Target Common Stock issued and outstanding immediately prior to the Effective Time (expressed as a number of shares) is referred to as the “Merger Consideration”. The Merger Consideration shall be comprised of the Preferred Share Consideration and the Common Share Consideration. For example, assume that the Debt Balance were $129,648,266 (comprised of the Existing Retail Indebtedness of $29,146,398, the Short Term Loan of $83,018,978 and the Assumed Loans of $17,482,890), the Closing Adjustment Amount due by Target to Acquiror were $2,000,000 and the Loan Escrows were $1,000,000. The Merger Consideration Amount would be as follows:

	$	303,422,124
Debt Balance	$	–129,648,266
Closing Adjustment Amount	$	–2,000,000
Loan Escrows	$	+1,000,000
Merger Consideration Amount	$	172,773,858

Further, assume that the Preferred Share Consideration were designated by Target to be 2,830,000 Acquiror Convertible Preferred Shares. The Preferred Share Consideration Amount would therefore be 2,830,000 x $50 = $141,500,000. The Common Share Consideration Amount would therefore be:

Merger Consideration Amount	$	172,773,858
Preferred Share Consideration Amount	$	–141,500,000
Common Share Consideration Amount	$	31,273,858

If the Calculation Price were $45 per share, the Common Share Consideration would be $31,273,858 ÷ $45 = 694,974.62 Acquiror Common Shares.

“Merger Consideration Amount” means (i) the excess of the Gross Value over the Debt Balance, (ii) increased by any Closing Adjustment Amount owed by Acquiror to Target pursuant to Section 8.04, if applicable, or decreased by any Closing Adjustment Amount owed by Target to Acquiror pursuant to Section 8.04, if applicable, as the case may be, plus (iii) the amount of any loan escrows held by Target’s lenders in connection with the Assumed Loans at the Effective Time, to the extent not taken into account in

computing the Debt Balance (the “Loan Escrows”). The sum of (ii) and (iii) is referred to as the “Aggregate Closing Adjustments”.

(b) At the Effective Time, except as set forth in subsections (c) and (d) below, each share of Target Common Stock issued and outstanding immediately prior to the Effective Time shall be converted into, and shall be canceled in exchange for, the right to receive a pro rata share of the Merger Consideration.

(c) Each share of Merger Subsidiary Common Shares issued and outstanding immediately prior to the Effective Time that is owned by Acquiror or by any Subsidiary of Acquiror, shall be converted into and become one share of common stock of the Surviving Entity.

(d) Each share of Target Common Stock that is owned by Target or any of the Target Subsidiaries, or by Acquiror, Merger Subsidiary or any other direct or indirect Subsidiary of Acquiror or Merger Subsidiary, shall be cancelled and retired and shall cease to exist and no cash, stock or any other consideration shall be delivered by Acquiror or Merger Subsidiary in exchange therefor.

4.02. Exchange Procedures.

(a) Custody of Certificates and Payment Fund. At or prior to the Effective Time, (i) Target shall acquire and hold for the Target Stockholders pursuant to a Power of Attorney between the Liquidating Trust and the Target Stockholders the certificate or certificates or affidavits of loss in accordance with Section 4.02(e) hereof (collectively, the “Certificates”), which immediately prior to the Effective Time represented shares of Target Common Stock and (ii) Acquiror shall deposit or cause to be deposited with the Liquidating Trust, for the benefit of the Target Stockholders for exchange in accordance with this Article IV, full certificates representing Acquiror Common Shares and Acquiror Convertible Preferred Shares in an amount sufficient to satisfy the aggregate Merger Consideration (such aggregate certificates being deposited hereinafter referred to as the “Payment Fund”). The Liquidating Trust shall, pursuant to irrevocable instructions, make payments out of the Payment Fund as provided for in this Article IV, and the Payment Fund shall not be used for any other purpose.

(b) Exchange Procedures for Target Common Stock. After surrender to the Liquidating Trust of a Certificate for cancellation, together with such Power of Attorney duly executed, and such other customary documents as may reasonably be required by the Liquidating Trust, upon the Effective Time, the holder of such Certificate shall be entitled to receive the Merger Consideration in exchange therefor for each share of Target Common Stock formerly represented by such Certificate. Such payment of the Merger Consideration shall be sent to such holder by the Liquidating Trust promptly after receipt by the Liquidating Trust of the Payment Fund, and the Power of Attorney duly executed, and such other customary documents as may reasonably be required by the Liquidating Trust, and the shares of Target Common Stock formerly represented by such

Certificate so surrendered shall forthwith be canceled. No interest will be paid or will accrue on any cash payable upon the surrender of a Certificate.

(c) No Further Ownership Rights in Stock. Until surrendered as contemplated by this Article IV, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration in respect of the shares of Target Common Stock formerly represented by such Certificate as contemplated by this Section 4.02. All shares paid upon the surrender for exchange of Certificates in accordance with the terms of this Article IV shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Target Common Stock represented by such Certificates. After the Effective Time, there shall be no further registration of transfers of shares of Target Common Stock outstanding immediately prior to the Effective Time on the records of Target, and if Certificates are presented to the Surviving Entity, they shall be canceled and exchanged as provided for, and in accordance with the procedures set forth, in this Article IV.

(d) Unregistered Transfer of Stock. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition of such payment that the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the Person requesting such payment shall have paid any transfer and any other Taxes required by reason of the payment to a Person other than the registered holder of the Certificate surrendered or shall have established to the satisfaction of the Surviving Entity that such Tax either has been paid or is not applicable.

(e) Lost Certificates. In the event that any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Entity, an indemnity against any claim that may be made against it with respect to such Certificate, the Liquidating Trust will issue, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration payable pursuant to this Article IV.

(f) Termination of Payment Fund. Any portion of the Payment Fund remaining unclaimed by holders of Shares immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Authority shall, to the extent permitted by applicable Law, become the property of the Liquidating Trust free and clear of all claims or interest of any Persons previously entitled thereto.

(g) No Liability. None of Acquiror, Merger Subsidiary, Target or the Liquidating Trust, or any employee, officer, director, agent or Affiliate thereof, shall be liable to any Person in respect of any cash from the Payment Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

4.03. Adjustments.

Notwithstanding anything in this Agreement to the contrary, if, between the date of this Agreement and the Effective Time, the outstanding shares of Target Common

Stock shall be changed into a different number, class or series of shares by reason of any stock dividend, subdivision, reclassification, recapitalization, stock split, combination or exchange of shares, then the Merger Consideration payable with respect thereto and any other amounts payable pursuant to this Agreement shall be appropriately adjusted in order to provide holders of Target Common Stock the same economic effect as contemplated by this Agreement.

4.04. Deposit.

Within one (1) Business Day after the execution of this Agreement, Acquiror shall deposit with the Cash Escrow Agent in cash Two Million Dollars ($2,000,000) which sum, together with any interest earned thereon prior to the Closing Date, is referred to as the “Deposit”, pursuant to the Cash Escrow Agreement for the benefit of the Target Stockholders. The Deposit shall be held in an interest bearing escrow account, pending disposition of the Deposit in accordance with Section 8.01(b). At Closing of the Merger, the Cash Escrow Agent shall remit the Deposit to Acquiror.

4.05. Deposit of Escrow Shares and Additional Escrow Shares.

(a) As soon as practicable after the Effective Time, and subject to, and in accordance with, the provisions of Section 7.07, Acquiror shall cause to be deposited with the Share Escrow Agent a certificate or certificates representing a number of Acquiror Common Shares (the “Escrow Shares”) equal to Three Million Five Hundred Thousand Dollars ($3,500,000) of the Merger Consideration Amount, which shall be registered in the name of the Share Escrow Agent as nominee for the holders of Certificates cancelled pursuant to Section 4.02(b). The Escrow Shares shall be beneficially owned by such holders so that such holders shall be entitled to any dividends or distributions (other than securities) and have the right to vote the shares and shall be available to compensate Acquiror for certain damages as provided in Section 7.07. The Escrow Shares shall be released in accordance with and subject to the provisions of Section 7.07 and the Share Escrow Agreement. At the Effective Time, the Escrow Shares will not have been registered under the Securities Act. In accordance with the Registration Rights Agreement, Acquiror will register the Escrow Shares with the SEC after Closing pursuant to the Registration Statement.

(b) As soon as practicable after the Effective Time, and subject to, and in accordance with, the Additional Share Escrow Agreement, Acquiror shall cause to be deposited with the Share Escrow Agent a certificate or certificates representing a number of shares of Acquiror Common Shares (the “Additional Escrow Shares”) equal to Four Million Five Hundred Thousand ($4,500,000) of the Merger Consideration Amount, which shall be registered in the name of the Share Escrow Agent as nominee for the holders of Certificates cancelled pursuant to Section 4.02(b). The Additional Escrow Shares shall be beneficially owned by such holders so that such holders shall be entitled to any dividends or distributions (other than securities) and have the right to vote the shares and shall be available to Acquiror as provided in the Additional Share Escrow Agreement. The Additional Escrow Shares shall be released in accordance with and

subject to the provisions of the Additional Share Escrow Agreement. At the Effective Time, the Additional Escrow Shares will not have been registered under the Securities Act.

No issues have been raised in writing in any examination by any taxing authority with respect to the Target Group which, by application of similar principles, reasonably could be expected to result in a material deficiency or increase in Tax for any other period not so examined. Section 6.02(i)(ii) of the Target Disclosure Letter lists all federal and state income Tax Returns filed with respect to the Target Group for taxable periods commencing on or after January 1, 2003 that have been audited, and indicates those Tax Returns, if any, that currently are the subject of audit.

(iii) Target and the Stockholders of Target as of April 1, 1998 made a valid election for Target to be treated as an “S corporation”, as that term is defined in Section 1361(a) of the Code, and such election will be in effect at the Closing Date. There are no grounds for the revocation of any such election and no such election will be revoked retroactively or otherwise.

(v) Target (A) shall be taxed as an S corporation through the Closing Date and has complied (and will comply) with all applicable provisions of the Code relating to an S corporation through the Closing Date, (B) has operated, and intends to continue to operate, in such a manner as to qualify as an S corporation from 1998 and through Closing, and (C) has not taken or omitted to take any action which would reasonably be expected to result in a challenge to its status as an S corporation during such time period, and, to the knowledge of Target, no such challenge is pending or threatened.

(vi) Target, for all taxable years commencing as of April 1, 1998, was eligible to and did validly elect to be taxed as an S corporation for federal income tax purposes and at all times thereafter continued such election and continued to be so eligible to be taxed as an S corporation for federal income tax purposes. The “built-in gain”, as of December 31, 2005, of the assets owned indirectly by Target as listed on Section 6.02(i)(vi) of the Target Disclosure Letter is true, accurate and complete.

(vii) Target shall not revoke its election to be taxed as an S corporation within the meaning of Sections 1361 and 1362 of the Code. Target shall not

take or allow any action that would result in the termination of its status as a validly electing S corporation within the meaning of Sections 1361 and 1362 of the Code.

(xi) Neither Target nor any of the Target Subsidiaries has made any election, or is required, to treat any asset of any Subsidiary as owned by another person for tax purposes (other than by reason of a Subsidiary being a “qualified S corporation subsidiary” or a “disregarded entity” for federal income tax purposes and any comparable provision of state, local or foreign law and except with respect to assets beneficially owned by a Subsidiary and record title to which is held by another entity).

(xii) Neither Target nor any of the Target Subsidiaries has requested, received or is subject to any written ruling of a taxing authority related to Taxes or has entered into any written and legally binding agreement with a taxing authority relating to Taxes.

(xiii) Neither Target nor any of its Subsidiaries (A) is a party to or is otherwise subject to any Tax allocation or sharing agreement other than pursuant to the Target Properties Leases or matters appearing in the land records and (B) has any liability for the Taxes of another person under law, by contract or otherwise.

(xv) Target is not and has not been subject to passive income tax under Section 1375 of the Code. Target and Target Subsidiaries have not had gross receipts for any three consecutive fiscal years subsequent to the taxable year ended December 31, 1998 of which more than twenty-five percent (25%) were “passive investment income” (as such term is defined in Section 1362(d)(3)(C) of the Code).

(xvi) Except as set forth in Section 6.02(i)(xvi) of the Target Disclosure Letter, Target has not acquired assets from another corporation in which the Target’s tax basis for the acquired assets was determined, in whole or in part, by reference to the tax basis of the acquired assets (or any other property) in the hands of the transferor.

(xvii) As of the Effective Time, Target will have no earnings and profits for federal income tax purposes that were accumulated in any taxable year to which the provisions of Sections 856 through 859 of the Code did not apply with respect to Target or any Predecessor. For purposes of this representation, “Predecessor” means any corporation the earnings and profits of which Target is required to take into account under Section 381(c) of the Code, by one or more successive applications of such Section.

(xviii) The tax basis as of December 31, 2005 of the Merger Properties and the Retail Properties is shown in Section 6.02(i)(xviii) of the Target Disclosure Letter and is true, accurate and complete.

(xix) Target agrees to timely file the federal and state income tax returns for Target and Target Subsidiaries for the final taxable year ending immediately prior to the Effective Time. Target will timely make an election under Treasury Regulation Section 1.1368-1(f)(3) to distribute all of its “subchapter C” earnings and profits through a deemed dividend to the Target Stockholders with respect to the final taxable year of Target ending immediately prior to the Effective Time.

(iv) None of the Target Group has received written notice of (A) any Liens arising under or pursuant to any applicable Environmental Law on any Target Property or (B) any action taken or in process which could subject any Target Property to such Liens.

(v) None of the Target Group has transported or arranged for the transportation of any Hazardous Material to any location which is the subject of any action, suit or proceeding that could be reasonably expected to result in claims against the Target Group related to such Hazardous Material for clean-up costs, remedial work, damages to natural resources or personal injury claims, including claims under CERCLA and the rules and regulations promulgated thereunder and, to the knowledge of Target, there is no reasonable basis for such claim.

(vi) No Hazardous Materials have been or are threatened to be spilled, released, discharged or disposed of at any site presently or formerly owned, operated, leased or used by the Target Group, or, to the knowledge of Target, are present in the soil, sediment, water or groundwater at any such site.

None of the Target Group has received any notice of a default that has not been cured under any of the Scheduled Contracts or is in default respecting any payment obligations thereunder beyond any applicable grace periods except where such default has not had or could not reasonably be expected to have a Target Material Adverse Effect or such default would not prevent or delay consummation of the Transaction.

(i) Each Target Material Contract is valid and binding on each Target Group party thereto, and none of the Target Group is in default under any Target Material Contract, except as would not (A) prevent or materially delay consummation of the Transaction, or (B) result in a Target Material Adverse Effect.

The terms and conditions of this Section 7.04 shall again apply to any inquiry or proposal made by any Person who withdraws a Superior Proposal or who made a Former Superior Proposal (after withdrawal or after such time as their proposal is a Former Superior Proposal).

(f) In response to the receipt of a Superior Proposal that has not been withdrawn and continues to constitute a Superior Proposal after Target’s compliance with Sections 7.04(b)—(e), the Target Board may withhold or withdraw its recommendation that the Target Stockholders vote in favor of the approval of the Transaction and, in the case of a Superior Proposal that is a tender or exchange offer made directly to the stockholders of Target, may recommend that the Target Stockholders accept the tender or exchange offer (any of the foregoing actions, whether by the Target Board or a committee thereof, a “Change in Recommendation”), if both of the following conditions are met:

(i) the Target Stockholder Meeting has not occurred; and

(ii) the Target Board has concluded in good faith, following the receipt of advice of its outside legal counsel, that, in light of such Superior Proposal, the failure of the Target Board to effect a Change in Recommendation would result in a breach of its fiduciary obligations to the Target Stockholders under applicable Law.

(g) Notwithstanding anything to the contrary contained in this Agreement, the obligation of Target to call, give notice of, convene and hold the Target Stockholder Meeting and to hold a vote of the Target Stockholders on this Agreement shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission to it of any Acquisition Proposal (whether or not a Superior Proposal), or by any Change in Recommendation.

7.05. Further Action; Reasonable Efforts.

(a) Upon the terms and subject to the conditions hereof, each of the parties hereto shall use its reasonable efforts to take, or cause to be taken, all appropriate action, and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws to consummate and make effective the Merger, including, without limitation, using its reasonable best efforts to obtain all Applicable Permits, consents, approvals, authorizations, qualifications and orders of Governmental Authorities and parties to contracts with Target and the Target Subsidiaries as are necessary for the consummation of the Merger and to fulfill the conditions to the Closing. In case, at any time after the Closing, any further action is necessary or desirable to carry out the purposes of this Agreement, each of the parties hereto shall use all reasonable efforts to cause its respective officers, employees and agents to take all such action.

(b) The parties hereto shall cooperate and assist one another in connection with all actions to be taken pursuant to Section 7.05(a), including the preparation and making of the filings referred to therein and, if requested, amending or furnishing additional information thereunder, including, subject to applicable Law and the Confidentiality Agreement, providing copies of all related documents to the non-filing party and their advisors prior to filing, and to the extent practicable none of the parties will file any such document or have any communication with any Governmental Authority without prior consultation with the other parties; provided, however, Acquiror may make any Exchange Act filings with the SEC with prior notice to Target to the extent possible (but without approval rights). Each party shall keep the others apprised of the content and status of any communications with, and communications from, any Governmental Authority with respect to the Merger. To the extent practicable, and as permitted by a Governmental Authority, each party hereto shall permit representatives of the other party to participate in meetings (whether by telephone or in Person) with such Governmental Authority.

(c) Each of the parties hereto agrees to cooperate and use its reasonable efforts to defend through litigation on the merits any Action, including administrative or judicial Action, asserted by any party in order to avoid the entry of, or to have vacated, lifted, reversed, terminated or overturned any decree, judgment,

injunction or other order (whether temporary, preliminary or permanent) that in whole or in part restricts, delays, prevents or prohibits consummation of the Merger, including, without limitation, by vigorously pursuing all available avenues of administrative and judicial appeal.

7.06. Public Announcements.

Acquiror and Target agree that no public release or announcement concerning the Merger shall be issued by either party without the prior consent of the other party, except as such release or announcement may be required by Law or the rules or regulations of the NYSE in which case the party required to make the release or announcement shall use its reasonable best efforts to allow the other party reasonable time to comment on such release or announcement in advance of such issuance; provided, however, if such other party fails to respond or comment on such release or announcement within two (2) Business Days of receipt of a draft of such release or announcement, the release or announcement shall be deemed approved.

7.07. Escrow and Indemnification.

(a) Escrow Fund. Within five (5) Business Days after the Effective Time, the Escrow Shares shall be registered in the name of, and be deposited with the Share Escrow Agent, such deposit to constitute the escrow fund (the “Escrow Fund”) and to be governed by the terms set forth herein and in the Share Escrow Agreement. The Escrow Fund shall consist of the Escrow Shares and shall be available to compensate Acquiror for Damages pursuant to the indemnification obligations of Target set forth in Section 7.07(b).

(b) Indemnification.

(i) Subject to the limitations set forth in this Section 7.07, the Target Stockholders will indemnify and hold harmless Acquiror, Acquiror OP and Merger Subsidiary and their respective officers, directors, agents and employees, and each Affiliate thereof (hereinafter referred to individually as an “Indemnified Person” and, collectively, as “Indemnified Persons”) from and against any and all losses, costs, damages, liabilities, taxes and expenses arising from claims, demands, actions, causes of action, including, without limitation, reasonable legal fees, (collectively, “Damages”) arising out of (A) any misrepresentation or breach of, or default in connection with, any of the representations, warranties, covenants and agreements given or made by the Target Group in this Agreement, the Target Disclosure Letter or any exhibit, schedule or certificate to, or delivered in connection with, this Agreement, (B) any of the matters described in Sections 6.02(f) and 6.02(g)(xx) of the Target

Disclosure Letter, (C) payment obligations under NPI’s or Target’s deferred compensation plan, pension plan, severance obligations and retirement obligations including, but not limited to, the Dollenberg Retirement Obligations, (D) any misrepresentation or breach by NPI under the Exchange Agreement, (E) any continuing liability in connection with the loans as more particularly described in Section 6.02(j)(viii) and Section 6.02(k) of the Target Disclosure Letter but excluding any continuing liability in connection with the Office Assumed Loans and (F) guarantees signed by Target with respect to loans relating to the Retail Properties (the “Retail Loan Guarantees”). The Escrow Fund shall be the security for this indemnity obligation subject to the limitations in this Agreement.

(ii) Acquiror and Target each acknowledge that such Damages, if any, would relate to unresolved contingencies existing at the Effective Time, which if resolved at the Effective Time would have led to a reduction in the total number of shares of Merger Consideration that Acquiror would have agreed to issue in connection with the Merger. Following the Effective Time, the right to obtain indemnification from the Escrow Fund, pursuant to the indemnification provisions of this Section 7.07 and the Share Escrow Agreement shall be Acquiror’s exclusive remedy for any breach by Target hereof or Damages described in Section 7.07(b)(i); provided, however, that the foregoing shall not limit liability of any Person or entity in the case of fraud or any intentional misrepresentation by such Person or entity.

(iii) Acquiror may not receive any Escrow Shares from the Escrow Fund unless and until the Claims Notice specifying an aggregate amount of Damages incurred by Acquiror in excess of Five Hundred Thousand Dollars ($500,000) (the “Indemnity Threshold”) have been delivered to the Share Escrow Agent as provided in Section 7.07(d) and such amount is determined pursuant to this Section 7.07 to be payable, after which Acquiror shall receive Escrow Shares for the amount of any Damages in excess of the Indemnity Threshold. In determining the amount of any Damage attributable to a breach, any materiality standard contained in a representation, warranty or covenant of Target shall be disregarded.

(iv) The Indemnity Threshold shall not apply to any Claims Notice (A) regarding the payment of any Transfer Taxes, (B) arising out of matters described in Sections 6.02(f) and 6.02(g)(xx) of the Target Disclosure Letter whereby Acquiror sustains actual Damages not reimbursed by insurance, (C) relating to payment obligations under NPI’s or Target’s deferred compensation plan, pension plan, severance obligations and retirement obligations including, but not limited to, the Dollenberg Retirement Obligations, (D) any misrepresentation or breach by NPI under the Exchange Agreement, (E) arising out of any continuing liability in connection with the loans as more particularly described in Section 6.02(j)(viii) and Section 6.02(k) of the Target Disclosure Letter but excluding any continuing liability in connection with the Office Assumed Loans or (F) regarding the Retail Loan Guarantees.

(c) Escrow Period. The escrow period (the “Escrow Period”) shall terminate at 11:59 p.m. Eastern Standard Time on the thirty-six (36) month anniversary of the Closing Date; provided, however, that a portion of the Escrow Fund, which is necessary to satisfy any unpaid fees due to the Share Escrow Agent and any unsatisfied claims specified in any Claims Notice theretofore delivered to the Share Escrow Agent prior to termination of the Escrow Period with respect to facts and circumstances existing prior to expiration of the Escrow Period, shall remain in the Escrow Fund until such claims have been resolved and such fees have been paid. Promptly after the Effective

Time, Acquiror shall deliver to the Share Escrow Agent a certificate specifying the Closing Date.

(d) Claims Upon Escrow Fund.

(i) Upon receipt by the Share Escrow Agent on or before the last day of the Escrow Period of a certificate signed by any officer of Acquiror (a “Claims Notice”):

(A) stating that Damages exist in an aggregate amount greater than the Indemnity Threshold; and

(B) specifying in reasonable detail the individual items included in the amount of Damages in such claim, the date each such item was paid, properly accrued or arose and the nature of the misrepresentation, breach of warranty or claim to which such item is related,

the Share Escrow Agent shall set aside Escrow Shares having a value equal to the amount of Damages in excess of the Indemnity Threshold.

(ii) Upon the earliest of: (A) receipt of written authorization from the Stockholders’ Agent or from the Stockholders’ Agent jointly with Acquiror to make such delivery, (B) receipt of written notice of a final decision in arbitration of the claim, or (C) in the event the claim set forth in the Claims Notice is uncontested by the Stockholders’ Agent as of the close of business on the next Business Day following the fifteenth (15th) day following receipt by the Share Escrow Agent of the Claims Notice; on the next Business Day, the Share Escrow Agent shall deliver the Escrow Shares or the portion of Escrow Shares set aside pursuant to Section 7.07(d)(i) to Acquiror.

(iii) For the purpose of compensating Acquiror for its Damages pursuant to this Agreement, the Escrow Shares in the Escrow Fund shall be valued at the last reported sale price of an Acquiror Common Share on the NYSE on the Business Day prior to the date such claim is paid.

(e) Objections to Claims. At the time of delivery of any Claims Notice to the Share Escrow Agent, a duplicate copy of such Claims Notice shall be delivered to the Stockholders’ Agent and for a period of fifteen (15) days after such delivery to the Share Escrow Agent of such Claims Notice, the Share Escrow Agent shall make no delivery of Escrow Shares pursuant to Section 7.07 unless and until the Share Escrow Agent shall have received written authorization from the Stockholders’ Agent to make such delivery. After the expiration of such fifteen (15) day period, the Share Escrow Agent shall make delivery of the Escrow Shares in accordance with Section 7.07, provided, that no such payment or delivery may be made if the Stockholders’ Agent shall object in a written statement to the claim made in the Claims Notice, and such statement shall have been delivered to the Share Escrow Agent and to Acquiror prior to the expiration of such fifteen (15) day period.

(f) Resolution of Conflicts; Arbitration.

(i) In case the Stockholders’ Agent shall so object in writing to any claim or claims by Acquiror made in any Claims Notice, Acquiror shall have fifteen (15) days after receipt by the Share Escrow Agent of an objection by the Stockholders’ Agent to respond in a written statement to the objection of the Stockholders’ Agent. If after such fifteen (15) day period there remains a dispute as to any claims, the Stockholders’ Agent and Acquiror shall attempt in good faith for thirty (30) days to agree upon the rights of the respective parties with respect to each of such claims. If the Stockholders’ Agent and Acquiror should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and shall be furnished to the Share Escrow Agent. The Share Escrow Agent shall be entitled to rely on any such memorandum and shall distribute the Escrow Shares from the Escrow Fund in accordance with the terms thereof.

(ii) If no such agreement can be reached after good faith negotiation, either Acquiror or the Stockholders’ Agent may, by written notice to the other, demand arbitration of the matter unless the amount of the damage or loss is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by three arbitrators. Within fifteen (15) days after such written notice is sent, Acquiror and the Stockholders’ Agent shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator. The decision of the arbitrators as to the validity and amount of any claim in such Claims Notice shall be binding and conclusive upon the parties to this Agreement, and notwithstanding anything in this Section 7.07, the Share Escrow Agent shall be entitled to act in accordance with such decision and make or withhold payments out of the Escrow Fund in accordance therewith.

(iii) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. Any such arbitration shall be held in Howard County, Maryland under the commercial rules then in effect of the American Arbitration Association and applying the laws of the State of Maryland. Acquiror, on the one hand, and Target Stockholders, on the other hand, shall each bear its/their own expenses (including attorneys’ fees and expenses) incurred in connection with any such arbitration. In the event the arbitrator or arbitrators find in favor of Acquiror as to the claim in dispute, all fees, costs, and the reasonable expenses of legal counsel incurred by Acquiror will be charged against the Escrow Fund in addition to the amount of the disputed claim. Similarly, in the event the arbitrator or arbitrators find in favor of Target as to the claim in dispute, all fees, costs, and the reasonable expenses of legal counsel incurred by Target will be paid by Acquiror. The fees and expenses of each arbitrator and the administrative fee of the American Arbitration Association shall be allocated by the arbitrator or arbitrators, as the case may be (or, if not so allocated, shall be borne equally by Acquiror, on the one hand, and Target Stockholders, out of the Escrow Fund, on the other hand).

(g) Stockholders’ Agent

(i) The Liquidating Trust shall be constituted and appointed as the Stockholders’ Agent for and on behalf of the Target Stockholders to execute and deliver the Share Escrow Agreement and for all other purposes thereunder, to give and receive notices and communications, to authorize delivery of Escrow Shares from the Escrow Fund in satisfaction of claims by Acquiror, to object to such deliveries, to agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to such claims, and to take all actions necessary or appropriate in the judgment of the Stockholders’ Agent for the accomplishment of the foregoing. Such agency may be changed by the holders of a majority in interest of the Escrow Fund from time to time upon not less than ten (10) days’ prior written notice to all of Target Stockholders and to Acquiror. No bond shall be required of the Stockholders’ Agent, and the Stockholders’ Agent shall receive no compensation for his services. Notices or communications to or from the Stockholders’ Agent shall constitute notice to or from each of Target Stockholders.

(ii) The Stockholders’ Agent shall not be liable for any act done or omitted hereunder as Stockholders’ Agent while acting in good faith, and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith. Target Stockholders shall severally indemnify the Stockholders’ Agent and hold him harmless against any loss, liability or expense incurred without bad faith on the part of the Stockholders’ Agent and arising out of or in connection with the acceptance or administration of his duties hereunder.

(h) Actions of the Stockholders’ Agent. A decision, act, consent or instruction of the Stockholders’ Agent shall constitute a decision of all of Target Stockholders and shall be final, binding and conclusive upon each and every Target Stockholder, and the Share Escrow Agent and Acquiror may rely upon any decision, act, consent or instruction of the Stockholders’ Agent as being the decision, act, consent or instruction of each and every Target Stockholder. The Share Escrow Agent and Acquiror are hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Stockholders’ Agent.

(i) Third-Party Claims. In the event that Acquiror becomes aware of a third-party claim which Acquiror believes may result in a demand against the Escrow Fund, Acquiror shall promptly notify the Stockholders’ Agent of such claim, and the Stockholders’ Agent and Target Stockholders shall be entitled, at their expense, to participate in any defense of such claim. Acquiror shall have the right in its sole discretion to settle any such claim; provided, however, that Acquiror may not effect the settlement of any such claim without the consent of the Stockholders’ Agent, which consent shall not be unreasonably withheld. In the event that the Stockholders’ Agent has consented to any such settlement, the Stockholders’ Agent shall have no power or authority to object under Section 7.07(e) or any other provision of this Section 7.07 to any claim by Acquiror against the Escrow Fund for indemnity in the amount of such settlement.

(j) The provisions of this Section 7.07 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 7.07 applies without the consent of such affected indemnitee and are intended to be for the benefit of, and will be enforceable by, each indemnified party, his or her heirs and his or her legal representatives.

(k) Additional Escrow Shares. The Additional Escrow Shares shall be held by the Share Escrow Agent pursuant to the terms of the Additional Share Escrow Agreement.

7.08. Intentionally Deleted.

7.09. Transfer Taxes.

Acquiror shall be liable for all Transfer Taxes (including any such taxes imposed post-Closing) applicable to any transfers relating to the properties set forth in Section 7.09(a) of the Target Disclosure Letter. Target and Acquiror shall each be liable for one-half of all Transfer Taxes (including any such taxes imposed post-Closing) applicable to any transfers relating to the properties set forth in Section 7.09(b) of the Target Disclosure Letter. Target shall be liable for all Transfer Taxes (including any such taxes imposed post-Closing) applicable to any transfers relating to the properties set forth in Section 7.09(c) of the Target Disclosure Letter. Target and Acquiror shall each be liable for one-half of all Transfer Taxes (including any such taxes imposed post-Closing) applicable to any transfers effectuated pursuant to the transactions contemplated in the PSA. Notwithstanding the foregoing, in no event shall liability under this Section 7.09 extend to any transfers taking place after the Effective Time.

7.10. Additional Acknowledgement #2. Upon the closing of the Retail Transaction, the Liquidating Trust shall deliver to the Surviving Entity a copy of the Additional Acknowledgement #2 by P. Douglas Dollenberg in the form attached hereto as Exhibit P.

7.11. Lender’s Approval.

(a) The current loan documents evidencing the Office Assumed Loans are listed in Section 7.11 of the Target Disclosure Letter (the “Loan Documents”).

(b) Target and Acquiror, with due diligence and in good faith, shall cooperate to attempt to obtain for the benefit of Acquiror, Acquiror OP and Merger Subsidiary legally binding letters or agreements, effective through the Closing Date, from the lenders who hold Office Assumed Loans and, if required, any nationally recognized rating agencies (if any) required by such lenders (the “Rating Agencies”), approving the transactions contemplated by this Agreement, to the extent applicable to the Office Assumed Loans, setting forth the amount of principal and interest outstanding as of the Closing Date, stating that there has not been, and there does not currently exist, any default under any of the Loan Documents and thereafter with due diligence and in good faith shall cooperate to consummate the closing of the Office Assumed Loans (each, a

“Lender’s Approval”). All documentation to be signed by Target Group, Acquiror or Acquiror OP in connection with any Lender’s Approval shall be subject to Acquiror’s prior written consent, not to be unreasonably withheld. Target shall pay (i) any assumption fee under the Loan Documents, (ii) the consent fee charged by the servicer and lenders, (iii) the legal fees of the servicer and lenders in connection with Lender’s Approval, (iv) any and all other fees and costs of the servicer, the lenders, and the Rating Agencies relating to Lender’s Approval including all structural, environmental, inspection, administrative, flood determination, insurance review and credit review fees of the servicer, the lenders, and the Rating Agencies relating to Lender’s Approval or otherwise relating to the Office Assumed Loans (the “Assumption Fees”). On the Closing Date if the Transaction is consummated, Acquiror shall reimburse Target for the Assumption Fees.

(c) Acquiror shall use its commercially reasonable efforts to obtain a release of NPI and Nottingham Investment Company from guarantees and/or indemnities for obligations accruing under the Office Assumed Loans from and after the date of assumption of the Office Assumed Loans.

Prior to the Effective Time, Target shall terminate those property management agreements listed in Section 7.12 of the Target Disclosure Letter.

7.13. Short Term Loan.

No later than one (1) Business Day prior to the Closing Date, Target shall obtain the Short Term Loan and will sign the Short Term Loan Documents as may be reasonably requested by Wachovia Bank, N.A. or Acquiror. The Short Term Loan Documents shall be subject to Acquiror’s prior written approval, which may be withheld in its reasonable discretion. The proceeds of the Short Term Loan will be used to repay in full the Existing Office Indebtedness and certain other obligations of Target. All liens securing the Existing Office Indebtedness shall be released at the time of the closing of the Short Term Loan. The Short Term Loan may be secured by a lien on the ownership interests of Target or Target Subsidiaries, provided that such lien is released upon the guaranty by Acquiror OP of the Short Term Loan.

7.14. Tenant Improvements.

Target shall use commercially reasonable efforts to complete all tenant improvement work with respect to the Pre-LOI Leases required to be performed at the commencement of the lease term (the “Pre-LOI TI Work”) prior to the Effective Time. If such work shall not be completed prior to the Effective Time, Target will enter into contracts with third parties, subject to Acquiror’s prior written approval, to complete such work. Target will enter into contracts with third parties, subject to Acquiror’s prior written approval, for all tenant improvements with respect to Target Properties Leases which are not Pre-LOI Leases.

7.15. Sewer System Escrow.

Upon the completion of all work to the Sewer System (as defined in the Acquisition Agreement), in the event any unspent funds remain in the escrow under such Acquisition Agreement (which agreement calls for the such remaining funds to be equally split between Honeygo Run Reclamation Center, Inc. and Target), Acquiror shall transmit all of the funds it receives from such escrow to the Liquidating Trust promptly upon receipt of such funds. Except as set forth in Section 8.04(viii) hereof, Acquiror shall not be responsible for the reimbursement to Target, any Target Subsidiary or the Liquidating Trust of any money spent as of the Closing Date on the Sewer System.

ARTICLE VIII.
ADDITIONAL AGREEMENTS

8.01. Inspection of the Target Properties.

(a) Right of Inspection. Acquiror shall have the right, at its own risk, cost and expense, at any time prior to Closing during normal business hours (i.e. Monday through Friday from 9:00 a.m. to 5:00 p.m. - federal holidays excepted) upon not less than forty-eight (48) hours prior notice to Target, and subject to the approval of the tenants under the Target Properties Leases with respect to any entry into the leased premises, to enter, or cause its agents or representatives to enter, upon any of the Target Properties for the purpose of making surveys, tests, test borings, inspections, investigations and architectural, structural, economic, environmental and other studies of any of the Target Properties as Acquiror may deem desirable. Target agrees that it shall reasonably cooperate with Acquiror in connection with any other information regarding the Target Properties reasonably requested by Acquiror and will provide or make available such information during the Inspection Period and at all periods thereafter through the Closing to the extent in Target’s possession. Acquiror shall, at Acquiror’s sole cost and expense, promptly and fully restore any damage or destruction to any of the Target Properties occurring as a result of any act or omission of Acquiror by reason of such tests, studies or investigations. Acquiror shall indemnify, defend and hold Target harmless from and against all loss, cost, damage or claim (including attorneys’ fees reasonably incurred, court costs and costs of investigation) arising out of or resulting from Acquiror’s exercise of the right and privilege granted to Acquiror contained in this Section 8.01, and the undertakings contained in this Section 8.01 shall survive Closing or prior termination of this Agreement.

(b) Inspection Period. Acquiror shall have the period commencing on the date hereof and ending at 5:00 p.m. Eastern Time on December 21, 2006 (the “Inspection Period”) to inspect the Target Properties and to conduct such tests and investigations as it deems advisable in order to determine that the Target Properties can be used for Acquiror’s intended use. If, during the Inspection Period, Acquiror is not reasonably satisfied with its findings thereof or for any other reason whatsoever, Acquiror shall notify Target in writing (prior to the expiration of the Inspection Period) in which event:

(i) the Deposit shall be returned to Acquiror; and

(ii) this Agreement shall be terminated in accordance with the provisions of Article X hereof.

It is expressly recognized and agreed by the parties that following expiration of the Inspection Period, Acquiror shall be deemed to have waived its termination right under this Section 8.01. If this Agreement is terminated by Target pursuant to Section 10.01(d)(i), the Cash Escrow Agent shall pay the Deposit to Target as Target’s final liquidated damages (it being understood that Target’s actual damages in the event of such default are difficult to ascertain and that such proceeds represent the parties’ best current estimate of such damages). Conversely, if this Agreement is terminated for any other reason whatsoever, the Deposit shall be promptly paid by the Cash Escrow Agent to Acquiror.

8.02. Prepayment of Indebtedness.

After obtaining Acquiror’s prior written consent, Target shall prepay the Existing Office Indebtedness listed in Section 8.02 of the Target Disclosure Letter prior to Closing, using a portion of the proceeds of the Short Term Loan, which Existing Office Indebtedness is secured by the properties listed in Section 8.02 of the Target Disclosure Letter, and in connection therewith shall pay all accrued interest, prepayment penalties and other charges related thereto or in connection therewith.

All other charges or fees customarily prorated and adjusted in similar transactions shall be adjusted as of the Closing Adjustment Time. All rent (other than prepaid rent) received from the tenants of the Merger Closing Properties shall be adjusted (prorated) as of the Closing Adjustment Time and paid in accordance with the following provisions, together with the following adjustments:

Closing occurs, such installment shall be adjusted as of the Closing Adjustment Time, with the Target Stockholders being entitled to the portion thereof attributable to the period of the month immediately preceding the Closing Date and Acquiror entitled to the balance of such monthly installment. Acquiror shall use commercially reasonable efforts to seek to collect unpaid rents and other amounts attributable to the period prior to the Closing Adjustment Time.

(ii) Acquiror shall be entitled to all basic rent and other sums due under any of the Merger Closing Properties Leases as of the Closing Adjustment Time with the exception of (a) common area maintenance (CAM) and real estate tax reimbursements attributable to periods prior to the Closing Adjustment Time; (b) the basic rent for the Closing month to which an Acquiror is entitled under (i) above, and (c) rental arrearages for periods preceding the Closing Adjustment Time, and (d) rents received from tenants prior to the Closing Adjustment Time which relate to periods prior to the Closing Adjustment Time.

Additionally, any tenant payments for special services which were specifically billed by Target or one of its Affiliates prior to the Closing Adjustment Time shall be owed to the Target Stockholders. All CAM payments from tenants received by Target or Target Subsidiaries which relate to periods after the Closing Adjustment Time shall be credited to Acquiror at Closing.

(iii) All security deposits under the Merger Closing Properties Leases (excluding letters of credit posted as security deposits as listed in Section 8.04(iii) of the Target Disclosure Letter) and rents received by Target and Target Subsidiaries which relate to periods after the Closing Adjustment Time shall be credited to Acquiror at Closing. Letters of credit posted as security deposits as listed in Section 8.04(iii) of the Target Disclosure Letter shall be assigned to Acquiror at Closing.

(iv) All Leasing Commissions and tenant improvements with respect to the Target Properties Leases signed after September 6, 2006 shall be assumed by Acquiror.

Any such unpaid amounts with regard to the Pre-LOI Leases as of the Closing Date, together with the estimated cost to complete the Pre-LOI TI Work after the Closing, shall be credited to Acquiror at Closing. To the extent Target has paid the Leasing Commissions and tenant improvements for leases signed after September 6, 2006, Target Stockholders shall receive a credit at Closing.

(v) Acquiror will be credited at Closing for an amount equal to any casualty insurance deductibles and uninsured losses relating to casualties which may have occurred at the Merger Closing Properties prior to the Closing.

(vi) If Acquiror collects any unpaid or delinquent rents relating to the Merger Closing Properties after the Closing Adjustment Time, Acquiror shall deliver to the Liquidating Trust the rent to which the Liquidating Trust is entitled relating to the period prior to the Closing Adjustment Time.

(vii) An amount equal to the Retained LC Amount shall be credited to Acquiror at Closing pursuant to Section 8.08.

(ix) Intentionally Deleted.

(x) If there are any liens or encumbrances applicable to Target Properties other than Permitted Liens, as of Closing, the amount to discharge such liens and encumbrances shall be credited to Acquiror at Closing.

(xi) If there shall be a breach of any of the representations, warranties, covenants or agreements made by Target herein and Target fails to cure such breach by the Outside Date, or if there shall be any outstanding liabilities or obligations of Target, Target Subsidiaries, NPI Exchange Entities or NPI Entities as of the Effective Time other than the Office Assumed Loans, the Short Term Loan, the Scheduled Contracts and the Target Properties Leases, the amount of the aggregate Damages resulting from such breach or such outstanding liabilities or obligations in excess of Two Hundred Fifty Thousand Dollars ($250,000) shall be credited to Acquiror at Closing.
