Section 2.1             Present Assignment And License Back.  It is intended by Borrower that this Assignment constitute a present, absolute assignment of the Leases, Rents, Lease Guaranties and Bankruptcy Claims, and not an assignment for additional security only.  Nevertheless, subject to the terms of this Section 2.1 and the Cash Management Agreement, Lender grants to Borrower a revocable license to collect, receive, use and enjoy the Rents and other sums due under the Lease Guaranties and Borrower shall hold such Rents and all sums received pursuant to any Lease Guaranty, or a portion thereof sufficient to discharge all current sums due on the Debt, in trust for the benefit of Lender for use in the payment of such sums.

Section 2.2             Notice To Lessees.  Borrower hereby authorizes and directs the lessees named in the Leases or any other future lessees or occupants of the Property and all Lease Guarantors to pay over to Lender or to such other party as Lender directs all Rents and all sums due under any Lease Guaranties upon receipt from Lender of written notice to the effect that Lender is then the holder of this Assignment and that an Event of Default (as defined in the Loan Agreement) exists, and to continue so to do until otherwise notified by Lender.

Section 2.3             Incorporation By Reference.  All representations, warranties, covenants, conditions and agreements contained in the Loan Agreement and the other Loan Documents as same may be modified, renewed, substituted or extended are hereby made a part of this Assignment to the same extent and with the same force as if fully set forth herein.

ARTICLE 3  —  REMEDIES

Section 3.1             Remedies of Lender.  Upon or at any time after the occurrence of an Event of Default, the license granted to Borrower in Section 2.1 of this Assignment shall automatically be revoked, and Lender shall immediately be entitled to possession of all Rents and sums due under any Lease Guaranties, whether or not Lender enters upon or takes control of the Property.  In addition, Lender may, at its option, without waiving such Event of Default, without regard to the adequacy of the security for the Debt, either in person or by agent, nominee or attorney, with or without bringing any action or proceeding, or by a receiver appointed by a court, dispossess Borrower and its agents and servants from the Property, without liability for trespass, damages or otherwise and exclude Borrower and its agents or servants wholly therefrom, and take possession of the Property and all books, records and accounts relating thereto and have, hold, manage, lease and operate the Property on such terms and for such period of time as Lender may deem proper and either with or without taking possession of the Property in its own name, demand, xxx for or otherwise collect and receive all Rents and sums due under all Lease Guaranties, including those past due and unpaid with full power to make from time to time all alterations, renovations, repairs or replacements thereto or thereof as Lender may deem proper and may apply the Rents and sums received pursuant to any Lease Guaranties to the payment of the following in such order and proportion as Lender in its sole discretion may determine, any law, custom or use to the contrary notwithstanding:  (a) all expenses of managing and securing the Property, including, without being limited thereto, the salaries, fees and wages of a managing agent and such other employees or agents as Lender may deem necessary or desirable and all expenses of operating and maintaining the Property, including, without being limited thereto, all taxes, charges, claims, assessments, water charges, sewer rents and any other liens, and premiums for all insurance which Lender may deem necessary or desirable, and the cost of all alterations, renovations, repairs or replacements, and all expenses incident to taking and retaining possession of the Property; and (b) the Debt, together with all costs and reasonable attorneys’ fees.  In addition, upon the occurrence of an Event of Default, Lender, at its option, may (1) complete any construction on the Property in such manner and form as Lender deems advisable, (2) exercise all rights and powers of Borrower, including, without limitation, the right to negotiate, execute, cancel, enforce or modify any Leases, obtain and evict tenants, and demand, xxx for, collect and receive all Rents from the Property and all sums due under any Lease Guaranties, (3) require Borrower to pay monthly in advance to Lender, or any receiver appointed to collect the Rents, the fair and reasonable rental value for the use and occupancy of such part of the Property as may be in possession of Borrower or (4) require Borrower to vacate and surrender possession of the Property to Lender or to such receiver and, in default thereof, Borrower may be evicted by summary proceedings or otherwise.

Section 3.2             Other Remedies.  Nothing contained in this Assignment and no act done or omitted by Lender pursuant to the power and rights granted to Lender hereunder shall be deemed to be a waiver by Lender of its rights and remedies under the Loan Agreement, the Note, or the other Loan Documents and this Assignment is made and accepted without prejudice to any of the rights and remedies possessed by Lender under the terms thereof.  The right of Lender to collect the Debt and to enforce any other

4

security therefor held by it may be exercised by Lender either prior to, simultaneously with, or subsequent to any action taken by it hereunder.  Borrower hereby absolutely, unconditionally and irrevocably waives any and all rights to assert any setoff, counterclaim or crossclaim of any nature whatsoever with respect to the obligations of Borrower under this Assignment, the Loan Agreement, the Note, the other Loan Documents or otherwise with respect to the Loan in any action or proceeding brought by Lender to collect same, or any portion thereof, or to enforce and realize upon the lien and security interest created by this Assignment, the Loan Agreement, the Note, or any of the other Loan Documents (provided, however, that the foregoing shall not be deemed a waiver of Borrower’s right to assert any compulsory counterclaim if such counterclaim is compelled under local law or rule of procedure, nor shall the foregoing be deemed a waiver of Borrower’s right to assert any claim which would constitute a defense, setoff, counterclaim or crossclaim of any nature whatsoever against Lender in any separate action or proceeding).

Section 3.3             Other Security.  Lender may take or release other security for the payment of the Debt, may release any party primarily or secondarily liable therefor and may apply any other security held by it to the reduction or satisfaction of the Debt without prejudice to any of its rights under this Assignment.

Section 3.4             Non Waiver.  The exercise by Lender of the option granted it in Section 3.1 of this Assignment and the collection of the Rents and sums due under the Lease Guaranties and the application thereof as herein provided shall not be considered a waiver of any default by Borrower under the Note, the Loan Agreement, the Leases, this Assignment or the other Loan Documents.  The failure of Lender to insist upon strict performance of any term hereof shall not be deemed to be a waiver of any term of this Assignment.  Borrower shall not be relieved of Borrower’s obligations hereunder by reason of (a) the failure of Lender to comply with any request of Borrower or any other party to take any action to enforce any of the provisions hereof or of the Loan Agreement, the Note or the other Loan Documents, (b) the release regardless of consideration, of the whole or any part of the Property, or (c) any agreement or stipulation by Lender extending the time of payment or otherwise modifying or supplementing the terms of this Assignment, the Loan Agreement, the Note, or the other Loan Documents.  Lender may resort for the payment of the Debt to any other security held by Lender in such order and manner as Lender, in its discretion, may elect.  Lender may take any action to recover the Debt, or any portion thereof, or to enforce any covenant hereof without prejudice to the right of Lender thereafter to enforce its rights under this Assignment.  The rights of Lender under this Assignment shall be separate, distinct and cumulative and none shall be given effect to the exclusion of the others.  No act of Lender shall be construed as an election to proceed under any one provision herein to the exclusion of any other provision.

Section 3.5             Bankruptcy.  (a)  Upon or at any time after the occurrence of an Event of Default, Lender shall have the right to proceed in its own name or in the name of Borrower in respect of any claim, suit, action or proceeding relating to the rejection of any Lease, including, without limitation, the right to file and prosecute, to the exclusion of Borrower, any proofs of claim, complaints, motions, applications, notices

5

and other documents, in any case in respect of the lessee under such Lease under the Bankruptcy Code.

(b)           If there shall be filed by or against Borrower a petition under the Bankruptcy Code, and Borrower, as lessor under any Lease, shall determine to reject such Lease pursuant to Section 365(a) of the Bankruptcy Code, then Borrower shall give Lender not less than ten (10) days’ prior notice of the date on which Borrower shall apply to the bankruptcy court for authority to reject the Lease.  Lender shall have the right, but not the obligation, to serve upon Borrower within such ten day period a notice stating that (i) Lender demands that Borrower assume and assign the Lease to Lender pursuant to Section 365 of the Bankruptcy Code and (ii) Lender covenants to cure or provide adequate assurance of future performance under the Lease.  If Lender serves upon Borrower the notice described in the preceding sentence, Borrower shall not seek to reject the Lease and shall comply with the demand provided for in clause (i) of the preceding sentence within thirty (30) days after the notice shall have been given, subject to the approval of the bankruptcy court having jurisdiction over the case and to the performance by Lender of the covenant provided for in clause (ii) of the preceding sentence.

ARTICLE 4  —  NO LIABILITY, FURTHER ASSURANCES

Section 4.1             No Liability of Lender.  This Assignment shall not be construed to bind Lender to the performance of any of the covenants, conditions or provisions contained in any Lease or Lease Guaranty or otherwise impose any obligation upon Lender.  Lender shall not be liable for any loss sustained by Borrower resulting from Lender’s failure to let the Property after an Event of Default or from any other act or omission of Lender in managing the Property after an Event of Default unless such loss is caused by the willful misconduct and bad faith of Lender.  Lender shall not be obligated to perform or discharge any obligation, duty or liability under the Leases or any Lease Guaranties or under or by reason of this Assignment and Borrower shall, and hereby agrees to, indemnify Lender for, and to hold Lender harmless from, any and all liability, loss or damage which may or might be incurred under the Leases, any Lease Guaranties or under or by reason of this Assignment and from any and all claims and demands whatsoever, including the defense of any such claims or demands which may be asserted against Lender by reason of any alleged obligations and undertakings on its part to perform or discharge any of the terms, covenants or agreements contained in the Leases or any Lease Guaranties.  Should Lender incur any such liability, the amount thereof, including costs, expenses and reasonable attorneys’ fees, shall be secured by this Assignment, the Security Instrument and the other Loan Documents and Borrower shall reimburse Lender therefor immediately upon demand and upon the failure of Borrower so to do Lender may, at its option, declare all sums secured by this Assignment, the Security Instrument and the other Loan Documents immediately due and payable.  This Assignment shall not operate to place any obligation or liability for the control, care, management or repair of the Property upon Lender, nor for the carrying out of any of the terms and conditions of the Leases or any Lease Guaranties; nor shall it operate to make Lender responsible or liable for any waste committed on the Property by the tenants or any other parties, or for any dangerous or defective condition of the Property including, without limitation, the presence of any Hazardous Substances (as defined in the

6

Environmental Indemnity), or for any negligence in the management, upkeep, repair or control of the Property resulting in loss or injury or death to any tenant, licensee, employee or stranger.

Section 4.2             No Mortgagee in Possession.  (a)  Nothing herein contained shall be construed as constituting Lender a “mortgagee in possession” in the absence of the taking of actual possession of the Property by Lender.  In the exercise of the powers herein granted Lender, no liability shall be asserted or enforced against Lender, all such liability being expressly waived and released by Borrower.

(b)           Further Assurances.  Borrower will, at the cost of Borrower, and without expense to Lender, do, execute, acknowledge and deliver all and every such further acts, conveyances, assignments, notices of assignments, transfers and assurances as Lender shall, from time to time, reasonably require for the better assuring, conveying, assigning, transferring and confirming unto Lender the property and rights hereby assigned or intended now or hereafter so to be, or which Borrower may be or may hereafter become bound to convey or assign to Lender, or for carrying out the intention or facilitating the performance of the terms of this Assignment or for filing, registering or recording this Assignment and, on demand, will execute and deliver and hereby authorizes Lender to execute in the name of Borrower to the extent Lender may lawfully do so, one or more financing statements, chattel mortgages or comparable security instruments, to evidence more effectively the lien and security interest hereof in and upon the Leases.
