A
 Original
Lender Loan
 Security
Instrument
  Lease Tenants Premises
  NOW, THEREFORE
 1.
    
    Definitions. The following terms shall have the following meanings for purposes of
this Agreement:
 1.1.
    
    Construction-Related Obligation means any obligation of Former Landlord (as hereinafter
defined) under the Lease to make, pay for, or reimburse Tenant for any alterations,
demolition, or other improvements or work at Landlords Premises, including Tenants
Premises. Construction-Related Obligation shall not include: (a) reconstruction or
repair following any fire, casualty or condemnation which occurs after the date of
attornment hereunder, but only to the extent of the insurance or condemnation proceeds
actually received by Successor Landlord for such reconstruction and repair, less Successor
Landlords actual expenses in administering such proceeds; or (b) day-to-day maintenance
and repairs.1.2.
    
    Foreclosure Event means (a) foreclosure under the Security Instrument; (b) any other
exercise
by Lender of rights and remedies (whether under the Security Instrument or under
applicable law, including bankruptcy law) as holder of the Loan and/or the Security
Instrument, as a result of which Successor Landlord becomes owner of Landlords Premises;
or (c) delivery by Former Landlord to Lender (or its designee or nominee) of a deed or
other conveyance of Former Landlords interest in Landlords Premises in lieu of any of
the foregoing.1.3.
    
    Former Landlord means Landlord and/or any other party that was landlord under the Lease at
any time before the occurrence of any attornment under this Agreement.1.4.
    
    Offset Right means any right or alleged right of Tenant to any offset, defense (other than
one arising from actual payment and performance, which payment and performance would bind a
Successor Landlord pursuant to this Agreement), claim, counterclaim, reduction, deduction,
or abatement against Tenants payment of Rent or performance of Tenants other obligations
under

##### 



the Lease, arising (whether under the Lease or other applicable law) from acts or omissions
of Former Landlord and/or from Former Landlords breach or default under the Lease.1.5.
    
    Rent means any fixed rent, base rent or
additional rent under the Lease.1.6.
    
    Successor Landlord means any party that becomes owner of Landlords Premises as the result
of a Foreclosure Event.1.7.
    
    Termination Right means any right of Tenant to cancel or terminate the Lease or to claim a
partial or total eviction arising (whether under the Lease or under applicable law) from
Former Landlords breach or default under the Lease.
 2.
    
    Subordination. The Lease, and all right, title and interest of the Tenant thereunder
and of the Tenant to and in the Landlords Premises, are, shall be, and shall at all times
remain, subject and subordinate to the Security Instrument, the lien imposed by the Security
Instrument, and all advances made under the Security Instrument.
 3.
    
    Payment to Lender. In the event Tenant receives written notice (the Rent Payment
Notice) from Lender or from a receiver for the Landlords Premises that there has been a
default under the Security Instrument and that rentals due under the Lease are to be paid to
Lender or to the receiver (whether pursuant to the terms of the Security Instrument or of
that certain Assignment of Rents and Leases executed by Landlord as additional security for
the Loan), Tenant shall pay to Lender or to the receiver, or shall pay in accordance with the
directions of Lender or of the receiver, all Rent and other monies due or to become due to
Landlord under the Lease, notwithstanding any contrary instruction, direction or assertion of
Former Landlord. Landlord hereby expressly and irrevocably directs and authorizes Tenant to
comply with any Rent Payment Notice, notwithstanding any contrary instruction, direction or
assertion of Landlord, and Landlord hereby releases and discharges Tenant of and from any
liability to Landlord on account of any such payments. The delivery by Lender or the receiver
to Tenant of a Rent Payment Notice, or Tenants compliance therewith, shall not be deemed to
(i) cause Lender to succeed to or to assume any obligations or responsibilities as landlord
under the Lease, all of which shall continue to be performed and discharged solely by the
applicable Landlord unless and until any attornment has occurred pursuant to this Agreement;
or (ii) relieve the applicable Former Landlord of any obligations under the Lease. Tenant
shall be entitled to rely on any Rent Payment Notice. Tenant shall be under no duty to
controvert or challenge any Rent Payment Notice. Tenants compliance with a Rent Payment
Notice shall not be deemed to violate the Lease. Tenant shall be entitled to full credit
under the Lease for any Rent paid to Lender pursuant to a Rent Payment Notice to the same
extent as if such Rent were paid directly to Former Landlord.
 4.
    
    Nondisturbance, Recognition and Attornment.
 4.1.
    
    No Exercise of Security Instrument Remedies against Tenant. So long as (i) the Lease
has not expired or otherwise been terminated by Former Landlord and (ii) there is no existing
default under or breach of the Lease by Tenant that has continued beyond applicable cure
periods (an Event of Default), Lender shall not name or join Tenant as a defendant in any
exercise of Lenders rights and remedies arising upon a default under the Security Instrument
unless applicable law requires Tenant to be made a party thereto as a condition to proceeding
against Former Landlord or prosecuting such rights and remedies. In the latter case, Lender
may join Tenant as a defendant in such action only for such purpose and not to terminate the
Lease or otherwise diminish or interfere with Tenants rights under the Lease or this
Agreement in such action.

otherwise been terminated by Former Landlord, (ii) there is no Event of Default, and (iii)

its terms, or to dispossess the Tenant, then, if and when Successor Landlord takes title to
Landlords Premises: (a) Successor Landlord shall not terminate or disturb Tenants
possession of Tenants Premises under the Lease, except in accordance with the terms of the
Lease and this Agreement; (b) Successor Landlord shall be bound to Tenant under all the
terms and conditions of the Lease (except as provided in this Agreement); (c) Tenant shall
recognize and attorn to Successor Landlord as Tenants direct landlord under the Lease as
affected by this Agreement; (d) the Lease shall continue in full force and effect as a
direct lease, in accordance with its terms (except as provided in this Agreement), between
Successor Landlord and Tenant; and (e) Successor Landlord shall have all the rights and
remedies of the landlord under the Lease, including, without limitation, rights or remedies
arising by reason of any Event of Default by Tenant under the Lease, whether occurring
before or after the Successor Landlord takes title to the Landlords Premises.4.3.
    
    Protection of Successor Landlord. Notwithstanding anything to the contrary in the
Lease or the Security Instrument, neither Lender nor Successor Landlord shall be liable for
or bound by any of the following matters:a.

may have
against any Former Landlord relating to any event or occurrence before the date of
attornment,

Tenants right
to exercise against Successor Landlord any Offset Right or Termination Right otherwise
available to Tenant because of events occurring after the date of attornment.b.
    
    Construction-Related Obligations. Any Construction-Related Obligation of Former
Landlord.c.

any
waiver of any terms of the Lease, made without Lenders written consent.f.

of the
Lease, in whole or in part, agreed between Former Landlord and Tenant, unless effected
unilaterally by Tenant pursuant to the express terms of the Lease.g.

    Lenders Right to Cure.

also be simultaneously provided to Lender. Notwithstanding anything to the contrary in
the Lease or this Agreement or the Security Instrument, before exercising any Termination
Right or Offset Right, Tenant shall provide Lender with notice of the breach or default
by Former Landlord giving rise to same (the Default Notice) and, thereafter, the
opportunity to cure such breach or default as provided for below.5.2.
    
    Lenders Cure Period. After Lender receives a Default Notice, Lender shall have a
period of thirty days beyond the time available to Former Landlord under the Lease in which
to cure the breach or default by Former Landlord, or, in the event that such cure cannot be
completed within such cure period, Lender shall have such reasonable period of time as is
required to diligently prosecute such cure to its completion. Lender shall have no
obligation to cure (and shall have no liability or obligation for not curing) any breach or
default by Former Landlord.
 6.
    
    Exculpation of Successor Landlord. Notwithstanding anything to the contrary in this
Agreement or the Lease, upon any attornment pursuant to this Agreement, the Lease shall be
deemed to have been automatically amended to provide that Successor Landlords obligations
and liabilities under the Lease shall never extend beyond Successor Landlords (or its
successors or assigns) interest, if any, in Landlords Premises from time to time,
including insurance and condemnation proceeds (except to the extent reinvested in the
Landlords Premises), Successor Landlords interest in the Lease, and the proceeds from any
sale or other disposition of Landlords Premises by Successor Landlord (collectively,
Successor Landlords Interest). Tenant shall look exclusively to Successor Landlords
Interest (or that of its successors and assigns) for payment or discharge of any obligations
of Successor Landlord under the Lease as affected by this Agreement. If Tenant obtains any
money judgment against Successor Landlord with respect to the Lease or the relationship
between Successor Landlord and Tenant, then Tenant shall look solely to Successor Landlords
Interest (or that of its successors and assigns) to collect such judgment. Tenant shall not
collect or attempt to collect any such judgment out of any other assets of Successor
Landlord.
 7.

and Tenant and Landlord regarding the subordination of the Lease to the Security Instrument
and the rights and obligations of Tenant, Lender and Landlord as to the subject matter of
this Agreement.7.4.

with the Lease, then this Agreement shall govern as between the parties and any Successor

may result in loss, injury or death to Tenant, or to any tenant, licensee, invitee, guest,
employee, agent
or stranger.c.
    
    Lender may assign to any person or entity its interest under the Security Instrument
and/or the
related loan documents, without notice to, the consent of, or assumption of any liability
to, any
other party hereto. In the event Lender becomes the Successor Landlord, Lender may assign
to
any other party its interest as the Successor Landlord without the consent of any other
party
hereto.7.6.
    
    Landlords Rights and Obligations. Except as provided in Section 3, nothing herein
contained is intended, nor shall it be construed, to abridge or adversely affect any right
