pay, bond or otherwise discharge, from time to time when the same shall become
due, all claims and demands of mechanics, materialmen, laborers and others
which, if unpaid, might result in, or permit the creation of, a lien on the
Mortgaged Property.

(b) Creation of Liens. Mortgagor shall not, without Mortgagee's consent, create,
place or permit to be created or placed or allow to remain, and shall discharge
and release within ten (10) days of the placing thereof, any deed of trust,
mortgage, trust deed, voluntary or involuntary lien, security interest or other
encumbrance against or covering the Mortgaged Property, other than the Permitted
Encumbrances, whether or not subordinate hereto.

(c) No Consent. Nothing in this Mortgage shall be deemed or construed in any way
as constituting the consent or request by Mortgagee, express or implied, to any
contractor, subcontractor, laborer, mechanic or materialman for the performance
of any labor or the furnishing of any material for any improvement,
construction, alteration or repair of the Premises. Mortgagor further agrees
that Mortgagee does not stand in any fiduciary relationship to Mortgagor.

SECTION 1.06.     Taxes and Other Charges.
(a) Taxes on the Premises. Mortgagor shall promptly pay when due and before any
penalty or interest may be added thereto, all taxes, assessments, vault, water
and sewer rents, rates, charges and assessments, levies, permits, inspection and
license fees and other governmental and quasi-governmental charges and any
penalties or interest for non-payment thereof, heretofore or hereafter imposed,
or which may become a lien, upon the Mortgaged Property or arising with respect
to the occupancy, use or possession thereof (collectively, "Impositions").
Mortgagor shall also pay any penalty, interest or cost for non-payment of
Impositions which may become due and payable.

(b) Receipts. Mortgagor shall furnish to Mortgagee upon Mortgagee's request,
proof of payment at the time same is made, and thereafter, upon receipt,
validated receipts showing payment in full of all Impositions.

(c) Increased Costs. In the event of the enactment after the date hereof of any
law in the state in which the Mortgaged Property is located or any other
governmental entity deducting from the value of the Mortgaged Property for the
purpose of taxation any lien or security interest thereon, or changing in any
way the laws for the taxation of mortgages, deeds of trust or other liens or
debts secured thereby, or the manner of collection of such taxes, so as to
affect this Mortgage, the Obligations, Mortgagee or the holders of the
Obligations, then, and in such event, Mortgagor shall, on demand, pay to
Mortgagee or such holder, or reimburse Mortgagee or such holder for payment of,
all taxes, assessments, charges or liens for which Mortgagee or such holder is
or may be liable as a result thereof, provided that if any such payment or
reimbursement shall be unlawful or would constitute usury or render the
Obligations wholly or partially usurious under applicable law,

                                        6
<PAGE>

then Mortgagee may, at its option, declare the Obligations immediately due and
payable or require Mortgagor to pay or reimburse Mortgagee for payment of the
lawful and non-usurious portion thereof.

SECTION 1.07.     Damage and Destruction.

(a) Mortgagor's Obligations. In the event of any damage to or loss or
destruction of the Premises, Mortgagor shall (i) promptly notify Mortgagee of
such event and take such steps as shall be necessary to preserve any undamaged
portion of the Premises and (ii) unless otherwise instructed by Mortgagee and so
long as any insurance proceeds paid to Mortgagee hereunder in respect of such
damage or destruction are made available by Mortgagee to Mortgagor (but without
imposing on Mortgagor any obligation to make such proceeds available to
Mortgagor other than as expressly required pursuant to Section 4.03(b) of the
Credit Agreement), promptly commence and diligently pursue to completion the
restoration, replacement and rebuilding of the Premises to the condition of the
Premises affected thereby immediately prior to such damage, loss or destruction
in accordance with plans and specifications approved, and with other provisions
for the preservation of the security hereunder established, by Mortgagee.

(b) Mortgagee's Rights; Application of Proceeds. In the event that (i) any
portion of the Premises is so damaged, destroyed or lost, (ii) such damage,
destruction or loss is covered, in whole or in part, by insurance required by
Section 1.04 hereof, and (iii) a claim is made by Mortgagee or Mortgager against
such insurance policy, then the proceeds of such insurance policy shall be
applied as provided in Section 4.03(b) of the Credit Agreement.

(c) Effect on the Obligations. Notwithstanding any loss, damage or destruction
referred to in this Section 1.07, Mortgagor shall continue to pay and perform
the Obligations as provided herein. Any reduction in the Obligations resulting
from such application shall be deemed to take effect only on the date of receipt
by Mortgagee of such insurance proceeds and application against the Obligations,
provided that if prior to the receipt by Mortgagee of such insurance proceeds
the Mortgaged Property shall have been sold on foreclosure of this Mortgage, or
shall have been transferred by deed in lieu of foreclosure of this Mortgage,
Mortgagee shall have the right to receive the same to the extent of any
deficiency found to be due upon such sale, with interest thereon at the rate and
as provided in the Credit Agreement together with attorneys' fees and
disbursements incurred by Mortgagee in connection with the collection thereof.

SECTION 1.08. Condemnation. (a) Mortgagor's Obligations; Proceedings. Mortgagor,
promptly upon obtaining knowledge of any pending or threatened institution of
any proceedings for the condemnation of the Premises, or of any right of eminent
domain, or of any other proceedings arising out of injury or damage to or
decrease in the value of the Premises, including a change in grade of any
street, shall notify Mortgagee of the threat or pendency thereof. Mortgagee may
participate in any such proceedings, and Mortgagor from time to time shall
execute and deliver to Mortgagee all instruments requested by Mortgagee or as
may be required to permit such participation. Mortgagor shall, at its expense,
diligently prosecute any such proceedings, shall deliver to Mortgagee copies of
all papers served in connection therewith and shall consult and cooperate with
Mortgagee, its attorneys and agents, in the carrying on and defense of any such
proceedings; provided that no settlement of any such proceeding shall be made by
Mortgagor without Mortgagee's consent, which consent shall not be unreasonably
withheld.

                                        7
<PAGE>

(b) Trustee's and Mortgagee's Rights to Proceeds. All proceeds of condemnation
awards or proceeds of sale in lieu of condemnation, and all judgments, decrees
and awards for injury or damage to the Premises greater than $5,000,000
(collectively, "Awards") are hereby assigned and shall be paid to Mortgagee.
Mortgagor authorizes Mortgagee to collect and receive the same, to give receipts
and acquittances therefor, and to appeal from any Awards.

(c) Application of Proceeds. Mortgagee shall have the right to apply any Awards,
first, to reimburse Mortgagee for all reasonable costs and expenses, and,
second, the remainder thereof in the manner provided in Section 4.03(b) of the
Credit Agreement as if such Awards were insurance proceeds. In the event that
Mortgagor shall have received all or any portion of such Awards, Mortgagor, upon
demand from Mortgagee, shall pay to Mortgagee an amount equal to the amount so
received by Mortgagor, to be applied as Mortgagee shall have the right pursuant
to this Section 1.08(c). Notwithstanding anything herein or at law or in equity
to the contrary, none of the Awards paid to Mortgagee under this Section 1.08(c)
shall be deemed trust funds and Mortgagee shall be entitled to dispose of the
same as provided in this Section 1.08(c).

(d) Effect on the Obligations. Notwithstanding any condemnation, taking or other
proceeding referred to in this Section 1.08, Mortgagor shall continue to pay and
perform the Obligations as provided herein. Any reduction in the Obligations
resulting from such application shall be deemed to take effect only on the date
of receipt by Mortgagee of such Awards and application against the Obligations,
provided that if prior to the receipt by Mortgagee of such Awards the Mortgaged
Property shall have been sold on foreclosure of this Mortgage, or shall have
been transferred by deed in lieu of foreclosure of this Mortgage, Mortgagee
shall have the right to receive the same to the extent of any deficiency found
to be due upon such sale, with interest thereon at the rate and as provided in
the Credit Agreement together with attorneys' fees and disbursements incurred by
Mortgagee in connection with the collection thereof.

SECTION 1.09. Contest. Notwithstanding anything to the contrary contained in
Section 1.03(c), Section 1.05 or Section 1.06 hereof, Mortgagor shall have the
right to contest in good faith and at its own expense the validity or
applicability of any duty or obligation described in Section 1.03(c) hereof, the
validity of any lien, encumbrance, charge or security referred to in Section
1.05 hereof and any Imposition imposed upon the Premises (a "Contest") by an
appropriate legal proceeding which proceeding must operate to prevent the
collection of such Impositions or other realization thereon and the sale or
forfeiture of the Mortgaged Property or any part thereof to satisfy the same;
provided that during the pendency of such Contest, Mortgagor shall provide
security reasonably satisfactory to Mortgagee (which security may be in the form
of a bond or undertaking deposited into a court, in either case sufficient to
remove the lien, encumbrance, charge or security in question), assuring the
discharge of Mortgagor's obligations that are the subject of such Contest
("Contested Impositions") and of any additional interest, charge, penalty or
expense arising from or incurred as a result of such Contest; and provided,
further, that if at any time payment of such Contested Impositions shall become
necessary to prevent (a) the delivery of a tax deed conveying the Mortgaged
Property because of non-payment or (b) the imposition of any civil or criminal
penalty or liability on Mortgagee or the holders of the Obligations, Mortgagor
shall pay the same in sufficient time to avoid the delivery of such

                                        8
<PAGE>

tax deed or the imposition of any such penalty or liability.

                                   ARTICLE II

                  Assignment of Leases, Rents and Other Sums

SECTION 2.01. Assignment. (a) Mortgagor hereby absolutely and presently
bargains, sells, transfers, assigns and sets over to Mortgagee, as further
security for the payment of the Obligations, all of its right, title and
interest in and to the Leases and the Rents payable thereunder and all rights of
Mortgagor thereunder and any and all deposits held as security under the Leases,
whether before or after foreclosure or during the full period of redemption, if
any, and shall, upon demand, deliver to Mortgagee an executed counterpart of
each Lease. The assignment of the Leases and Rents, and of the aforesaid rights
with respect thereto, is intended to be and is an absolute present assignment
from Mortgagor to Mortgagee and not merely the passing of a security interest.
Such assignment and grant shall continue in effect until the Obligations are
paid, the execution of this Mortgage constituting and evidencing the irrevocable
consent of Mortgagor to the entry upon and taking possession of the Premises by
Mortgagee pursuant to such grant, whether foreclosure has been instituted or not
and without applying for a receiver. Until the occurrence of an Event of Default
hereunder, Mortgagor shall be entitled, subject to any provisions of the Loan
Documents and the Permitted Hedges providing otherwise, to collect and receive
the Rents and agrees to apply the same in the ordinary course of business. Such
right of Mortgagor to collect and receive said Rents shall be automatically
revoked upon the occurrence of an Event of Default and thereafter Mortgagee
shall have the right and authority to exercise any of the rights or remedies
referred to or set forth in Article V hereof. In addition, upon such an Event of
Default, Mortgagor shall promptly pay to Mortgagee (i) all rent prepayments and
security or other deposits paid to Mortgagor pursuant to any lease assigned
hereunder and (ii) all charges for services or facilities or for escalation
which were paid pursuant to any such Lease to the extent allocable to any period
from and after such Event of Default. Nothing contained in this Section 2.01(a)
shall be construed to bind Mortgagee to the performance of any of the covenants,
conditions or provisions contained in any Lease or otherwise to impose any
obligation on Mortgagee prior to accepting receipt of such Rent (including any
liability under the covenant of quiet enjoyment contained in any Lease or under
any applicable law in the event that any tenant shall have been joined as a
party defendant in any action to foreclose this Mortgage and shall have been
barred and foreclosed thereby of all right, title and interest and equity of
redemption in the Premises), except that Mortgagee shall be accountable for any
money actually received pursuant to such assignment. Mortgagor hereby further
grants to Mortgagee the right, after the occurrence of an Event of Default
hereunder, to notify the tenant under any Lease of the assignment thereof and
(1) to demand that the tenant under any Lease pay all amounts due thereunder
directly to Mortgagee, (2) to enter upon and take possession of the Premises for
the purpose of collecting the Rents, (3) to dispossess by the usual summary
proceedings any tenant defaulting in the payment thereof, (4) to let the
Premises, or any part thereof, and (5) to apply the Rents, after payment of all
necessary charges and expenses, on account of the Obligations.

(b) Mortgagor shall, as and when requested from time to time by Mortgagee,

                                        9
<PAGE>

execute, acknowledge and deliver to Mortgagee, in form reasonably acceptable to
Mortgagee and Mortgagor, one or more general or specific assignments of the
lessor's interest under any Lease. Mortgagor shall, on demand, pay to Mortgagee,
or reimburse Mortgagee for the payment of any reasonable costs or expenses
incurred in connection with the preparation or recording of any such assignment.

SECTION 2.02. Leases and Rents. (a) Mortgagor shall (i) perform or cause to be
performed all the lessor's obligations under any Lease, (ii) enforce (including
the termination and cancellation of any Lease, so long as the same is a bona
fide enforcement of Mortgagor's right as lessor under any such Lease and such
termination or cancellation, either by itself or in the aggregate with other
terminations and cancellations, shall not diminish or impair the security of
this Mortgage) the performance by the lessee under its respective Lease of all
of said lessee's obligations thereunder, (iii) give Mortgagee prompt notice and
a copy of any notice of default, event of default, termination or cancellation
sent or received by Mortgagor in respect of any Lease producing an annual income
to Mortgagor of $100,000 or more (such Lease, a AMaterial Lease"); but nothing
contained herein shall preclude Mortgagor from modifying, supplementing or
amending any existing Lease or preclude Mortgagor from entering, subject to
Section 2.02(b) hereof, into additional Leases which may, from time to time, be
modified, supplemented, amended, terminated or cancelled by Mortgagor subject to
the provisions of this Section 2.02(a).

(b) Mortgagor agrees that any Lease, the termination of which could reasonably
be expected to have a Material Adverse Effect, shall contain the following
provision:

A[Tenant] acknowledges and agrees that this [Lease] is subject and subordinate
to that certain Tranche B Mortgage, Assignment of Leases and Rents, Security
Agreement and Fixture Filing, dated as of March __, 2000, made by [Landlord] in
favor of Citibank, N.A. as collateral agent for the lenders listed therein
(together with any amendment, assignment or other modification thereof made at
any time, the AMortgage"), such subordination being self-operative and requiring
no further instrument of subordination. If at any time the mortgagee under the
Mortgage (together with successors and assigns of such mortgagee, AMortgagee")
or any other person or the successors or assigns of any of the foregoing shall
succeed to the rights of [Landlord] (any such successor, a ASuccessor
Landlord"), then [Tenant] shall, at the election and upon the request of any
Successor Landlord, fully and completely attorn to and recognize such Successor
Landlord as the landlord under this [Lease] upon the then executory terms of
this [Lease], except that such Successor Landlord shall not be (a) liable for
any act or omission of any previous [landlord] under this [Lease], (b) obligated
to repair, replace, rebuild or restore any portion of the [premises demised
under the Lease] in the event of damage, destruction or taking by eminent
domain, (c) subject to any offset or defense which [Tenant] may have against any
previous [landlord] under this [Lease], (d) bound by any amendment or
modification of the [Lease] unless Mortgagee has approved such amendment or
modification in advance, and (e) obligated to perform any work in the [premises
demised under the Lease] other than work that is required to be performed under
the [Lease]. If any act or omission by [Landlord] shall give [Tenant] the right,
immediately or after the lapse of time, to cancel or terminate this [Lease] in
whole or in part or to claim such cancellation or termination on the basis of a
partial or total eviction, [Tenant] shall not exercise any such right until (1)
it shall have given written notice of such act or omission to Mortgagee, and (2)

                                       10
<PAGE>

a reasonable period for remedying such act or omission shall have elapsed
following such notice and following the time when Mortgagee shall have become
entitled under this Mortgage to remedy the same."

(c) (i) Except as provided in Section 2.02(a) hereof, Mortgagor shall not,
without Mortgagee's consent, (A) assign, mortgage, pledge or otherwise transfer,
dispose of or encumber, whether by operation of law or otherwise, any Lease or
the Rents, (B) accept or permit the acceptance of a prepayment of any amounts
payable under such Lease for more than one month in advance of the due date
therefor, (C) enter into, amend, modify, cancel, terminate or accept a surrender
of any Lease or (D) enter into any Lease (1) with Mortgagor or any affiliate of
Mortgagor or its constituent partners or (2) which would be a "disqualified
lease", as defined in Section ' 168(h)(1)(B)(ii) of the Internal Revenue Code of
1986, as amended.

(ii) Supplementing the provisions of Section 2.02(c)(i) hereof, if the lessee
under any Lease (or any receiver, trustee, custodian or other party who succeeds
to the rights of any lessee) rejects or disaffirms such Lease pursuant to any
bankruptcy law, Mortgagor hereby assigns to Mortgagee the proceeds of any claims
(including the right to retain or apply any security deposits) that Mortgagor
may have against the lessee (or receiver, trustee, custodian or other party who
succeeds to the rights of any lessee) and any guarantor of any of the Leases,
under any one or more of the Leases or any guaranty thereof based upon any
breach by such lessee of the terms and provisions of the applicable Lease
(including any claim that Mortgagor may have by reason of a termination,
rejection or disaffirmance of such Lease pursuant to any bankruptcy law), and
the use and occupancy of the premises demised thereby, whether or not pursuant
to the applicable Lease (including any claim for use and occupancy arising under
any bankruptcy law). Mortgagor, immediately upon obtaining knowledge of any such
breach or use by any such lessee, shall notify Mortgagee of any such breach or
use. Except in respect of any Lease that is not a Material Lease (in which case
Mortgagor shall proceed in Mortgagor's and Mortgagee's behalf pursuant to
Section 2.02(c)(ii)(B) hereof), Mortgagee shall have the sole right to elect,
either:

(A) to proceed against such lessee or guarantor as if it were the named lessor
thereunder, in Mortgagor's name or in Mortgagee's name as agent for Mortgagor,
and Mortgagor agrees to cooperate with Mortgagee in such action and shall
execute any and all documents reasonably required in furtherance of such action;
or

(B) to have Mortgagor proceed in Mortgagor's and Mortgagee's behalf in which
event Mortgagee may participate in any such proceedings, and Mortgagor from time
to time shall deliver to Mortgagee all instruments reasonably requested by
Mortgagee or as may be required to permit such participation. Mortgagor shall,
at its expense, diligently prosecute any such proceedings, shall deliver to
Mortgagee copies of all papers served in connection therewith and shall consult
and cooperate with Mortgagee, its attorneys and agents, in the carrying on and
defense of any such proceedings; provided that no settlement of any such
proceeding shall be made by Mortgagor without Mortgagee's consent.

                                   ARTICLE III

                  Additional Advances; Expenses; Indemnity

                                       11
<PAGE>

SECTION 3.01. Additional Advances and Disbursements. (a) Mortgagor agrees that
if an Event of Default occurs hereunder, then Mortgagee shall have the right
without notice to Mortgagor to advance all or any part of amounts owing or to
perform any or all required actions. No such advance or performance shall be
deemed to have cured such default by Mortgagor or any Event of Default with
respect thereto. All sums advanced and all expenses incurred by Mortgagee in
connection with such advances or actions, and all other sums advanced or
expenses incurred by Mortgagee hereunder or under applicable law (whether
required or optional and whether indemnified hereunder or not) shall be part of
the Obligations, shall bear interest at the rate and as provided in the Credit
Agreement and shall be secured by this Mortgage.

(b) This Mortgage secures not only existing indebtedness, but also future or
additional protective advances made in each case pursuant hereto or to the
Credit Agreement, the Permitted Hedges, if any, whether such advances are
obligatory or optional.

SECTION 3.02. Other Expenses. Mortgagor shall pay or, within ten (10) days of
demand therefor, reimburse Mortgagee or any holder of the Obligations for the
payment of any and all reasonable costs or expenses (including reasonable
attorneys' fees and disbursements) incurred in connection with (a) an Event of
Default by Mortgagor hereunder, or (b) the exercise or enforcement by or on
behalf of Mortgagee or any holder of the Obligations of any of its rights or of
Mortgagor's obligations under the Loan Documents or the Permitted Hedges.

SECTION 3.03. Indemnity. Mortgagor shall indemnify and hold harmless Mortgagee,
the holders of the Obligations and their respective officers, directors,
employees and agents (the "indemnified parties") from and against any and all
losses, damages, claims, costs and expenses (including attorneys' fees and
disbursements) which may be imposed on, incurred by or asserted against any of
the indemnified parties in connection with any transaction in any way connected
with the Mortgaged Property, the Loan Documents or the Permitted Hedges, except
to the extent any such loss, damage, claim, cost or expense is the result of the
willful misconduct or gross negligence of the indemnified party. Any amount
payable under this Section 3.03 shall be deemed a demand obligation, shall be
added to and become a part of the Obligations, shall bear interest at the rate
and as provided in the Credit Agreement if not paid within ten (10) days of
demand therefore, and shall be secured by this Mortgage.

SECTION 3.04. Interest After Default. If any payment due hereunder, under the
other Loan Documents or under a Permitted Hedge is not paid in full when due,
whether by acceleration or otherwise, then the same shall bear interest
hereunder at the rate and as provided in the Credit Agreement, and such interest
shall be added to and become a part of the Obligations and shall be secured
hereby.

                                   ARTICLE IV

                  Sale or Transfer of the Premises

SECTION 4.01.     Continuous Ownership. Mortgagor acknowledges that the
continuous ownership of the Mortgaged

                                       12
<PAGE>

Property by Mortgagor, except as otherwise permitted in the other Loan
Documents, is of a material nature to the transaction hereinabove described and
Mortgagee's agreement to create the Obligations. Mortgagor=s causing the
following activities, whether voluntarily or involuntarily, without Mortgagee=s
prior written consent, shall subject Mortgagor to the remedies set forth at
Section 5.02 hereof: (a) other than in respect of a parcel of the Mortgaged
Property that is not a Material Portion of the Premises transferred in the
context of a settlement with an adjoining landowner regarding the ownership or
use of such parcel, selling, leasing, granting, conveying, assigning or
otherwise transferring, by operation of law or otherwise, or (b) granting an
option which or taking any action which pursuant to the terms of any agreement
to which Mortgagor is a party may result in any transaction described in clause
(a) above of, the Mortgaged Property, or any legal, beneficial or equitable
interest (excluding interests in Leases that are not Material Leases) therein
(the foregoing, collectively or severally, "Transfer"). For purposes of this
Mortgage, but without limiting the foregoing, (i) the issuance of any equity
interest in Mortgagor (whether stock, partnership interest or otherwise) not in
accordance with and pursuant to the Loan Documents and the Permitted Hedges,
shall be deemed a Transfer of the Mortgaged Property, (ii) a Transfer of all or
substantially all of the assets of Mortgagor shall be deemed a Transfer of the
Mortgaged Property, (iii) subject to Section 1.03(c) hereof, the execution and
delivery of any documentation relating to a proposed zoning lot merger or the
execution and delivery of any other documentation effecting or purporting to
effect, or the taking or suffering of any other action effecting or purporting
to effect, a transfer of, or the granting of a right to utilize, any development
rights appurtenant to the Mortgaged Property shall be deemed a Transfer of the
Mortgaged Property, and (iv) any person or legal representative of Mortgagor to
whom Mortgagor's interest in the Mortgaged Property passes by operation of law,
or otherwise, shall be bound by the provisions of this Mortgage. The provisions
of this Section 4.01 shall apply to each and every such Transfer of all or any
portion of the Mortgaged Property or any legal or equitable interest therein,
regardless whether or not Mortgagee has consented to, or waived by its action or
inaction its rights hereunder with respect to any previous Transfer of all or
any portion of the Mortgaged Property or any legal or equitable interest
therein.

                                    ARTICLE V

                  Defaults and Remedies

SECTION 5.01.     Events of Default. The term "Event of Default", as used in
this Mortgage, shall mean the occurrence of any of the following events:

(a) if default shall be made in the payment, after any applicable notice and
cure period, of any amounts required to be paid under the Notes, hereunder or
under any other Loan Document or under a Permitted Hedge, whether of principal,
interest, premium, fee or otherwise, and whether on any stated due date, upon
demand, at maturity or upon acceleration; or

(b) an Event of Default, as such term is defined in the Credit Agreement; or

(c) subject to Mortgagor=s right to contest same set forth in Section 1.09

<PAGE>

(d) if Mortgagor shall fail at any time to obtain, provide, maintain, keep in
force or, within ten (10) days after request therefor, deliver to Mortgagee, the
insurance policies required by Section 1.04 hereof; or

(e) subject to Mortgagor=s right to contest same set forth in Section 1.09
hereof, if any claim of priority (except a claim based upon a Permitted
Encumbrance) to this Mortgage or any other document or instrument securing the
Obligations by title, lien or otherwise shall be upheld by any court of
competent jurisdiction or shall be consented to by Mortgagor.

SECTION 5.02. Remedies. Upon the occurrence of any one or more Events of
Default, or any Transfer without the consent of Mortgagee, Mortgagee may, in
addition to any rights or remedies available to it hereunder or under the other
Loan Documents or the Permitted Hedges and to the extent permitted by applicable
law, take such action personally or by its agents or attorneys, with or without
entry, and without notice, demand, presentment or protest (each and all of which
are hereby waived except as expressly provided otherwise herein), as it deems
necessary or advisable to protect and enforce its rights and remedies against
Mortgagor and in and to the Mortgaged Property, including the following actions,
each of which may be pursued concurrently or otherwise, at such time and in such
order as Mortgagee may determine, in its sole discretion, without impairing or
otherwise affecting its other rights or remedies:

(a) declare the entire balance of the Obligations to be immediately due and
payable, and upon any such declaration, the entire unpaid balance of the
Obligations shall become and be immediately due and payable, without
presentment, demand, protest or further notice of any kind, all of which are
hereby expressly waived by Mortgagor (except as expressly provided otherwise
herein); or

(b) institute a proceeding or proceedings, judicial or otherwise, for the
complete or partial foreclosure of this Mortgage under any applicable provision
of law; or

(c) sell the Mortgaged Property, and all estate, right, title, interest, claim

more sales, as an entirety or in parcels, with such elements of real and/or
personal property, and at such time and place and upon such terms as it may deem
expedient, or as may be required by applicable law, and in the event of a sale,
by foreclosure or otherwise, of less than all of the Mortgaged Property, this
Mortgage shall continue as a lien and security interest on the remaining portion
of the Mortgaged Property; or

(d) institute an action, suit or proceeding in equity for the specific
performance of any of the provisions contained in the Loan Documents or the
Permitted Hedges; or

(e) apply for the appointment of a receiver, custodian, trustee, liquidator or

permitted under applicable law, as a matter of right and without regard to, or
the necessity to disprove, the adequacy of the security for the Obligations or
the solvency of Mortgagor or any other person liable for the payment of the
Obligations, and Mortgagor and each other person so liable waives or shall be
deemed to have waived such necessity and consents or shall be deemed to have
consented to such appointment; or

                                       14
<PAGE>

(f) enter upon the Premises, and exclude Mortgagor and its agents and servants
wholly therefrom, without liability for trespass, damages or otherwise, and take
possession of all books, records and accounts relating thereto and all other

Mortgaged Property and of such books, records and accounts to Mortgagee on
demand after the happening of any Event of Default; and having and holding the

and conduct the business thereof, either personally or by its superintendents,

subsection (f) of this Section 5.02, including all amounts necessary to pay

deemed to have entered upon or taken possession of the Mortgaged Property except
upon the exercise of its option to do so, evidenced by its demand and overt act

possession by reason of such entry or taking possession. Mortgagee shall not be
liable to account for any action taken pursuant to any such exercise other than
for Rents actually received by Mortgagee, nor liable for any loss sustained by
Mortgagor resulting from any failure to let the Premises, or

requirements of law and except as otherwise provided herein, the following

Mortgaged Property under or by virtue of this Article V, whether made under the
power of sale herein granted or by virtue of judicial proceedings or of a
judgment or decree of foreclosure and sale:

(a) Mortgagee may conduct any number of sales from time to time. The power of
sale set forth in Section 5.02(c) hereof shall not be exhausted by any one or
more such sales as to any part of the Mortgaged Property which shall not have
been sold, nor by any sale which is not completed or is defective in Mortgagee's
opinion, until the Obligations shall have been paid in full.

(b) Any sale may be postponed or adjourned by public announcement at the time
and place appointed for such sale or for such postponed or adjourned sale
without further notice. Without limiting the foregoing, in case Mortgagee shall
have proceeded to enforce any right or remedy under this Mortgage by receiver,
entry or otherwise, and such proceedings have been discontinued or abandoned for
any such reason or shall have been determined adversely to Mortgagee, then in
every such case Mortgagor and Mortgagee shall be restored to their former
positions and rights hereunder, and all rights, powers and remedies of Mortgagee
shall continue as if no such proceeding had been taken.

(c) After each sale, Mortgagee or an officer of any court empowered to do so
shall execute and deliver to the purchaser or purchasers at such sale a good and
sufficient instrument or instruments granting, conveying, assigning and
transferring all right, title and interest of Mortgagor in and to the property
and rights sold and shall receive the proceeds of said sale or sales and apply
the same as herein provided. Mortgagee is hereby appointed the true and lawful
attorney-in-fact of Mortgagor, which appointment is irrevocable and shall be
deemed to be coupled with an interest, in Mortgagor's name and stead, to make
all necessary conveyances, assignments, transfers and deliveries of the property
and rights so sold, and for that purpose Mortgagee may execute all necessary
instruments of conveyance, assignment, transfer and delivery, and may substitute
one or more persons with like power, Mortgagor hereby ratifying and confirming
all that said attorney or such substitute or substitutes shall lawfully do by
virtue thereof. Nevertheless, Mortgagor, if requested by Mortgagee, shall ratify
and confirm any such sale or sales by executing and delivering to Mortgagee or
such purchaser or purchasers all such instruments as may be advisable, in
Mortgagee's judgment, for the purposes as may be designated in such request.

(d) Any and all statements of fact or other recitals made in any of the
instruments referred to in subsection (c) of this Section 5.03 given by
Mortgagee as to nonpayment of the Obligations, or as to the occurrence of any
Event of Default, or as to Mortgagee having declared all or any of the
Obligations to be due and payable, or as to the request to sell, or as to notice
of time, place and terms of sale and of the property or rights to be sold having
been duly given, or as to any other act or thing having been duly done by
Mortgagor or by Mortgagee in connection with the exercise of the remedies
described in this Section 5.03(d) shall be taken as conclusive and

                                       16
<PAGE>

binding against all persons as to evidence of the truth of the facts so stated
and recited absent manifest error. Mortgagee may appoint or delegate any one or
more persons as agent to perform any act or acts necessary or incident to any
sale so held, including the posting of notices and the conduct of sale.

(e) The receipt of Mortgagee for the purchase money paid at any such sale, or
the receipt of any other person authorized to receive the same, shall be
sufficient discharge therefor to any purchaser of any property or rights sold as
aforesaid, and no such purchaser, or its representatives, grantees or assigns,
after paying such purchase price and receiving such receipt, shall be bound to
see to the application of such purchase price or any part thereof upon or for
any trust or purpose of this Mortgage or, in any manner whatsoever, be
answerable for any loss, misapplication or nonapplication of any such purchase
money, or part thereof, or be bound to inquire as to the authorization,
necessity, expediency or regularity of any such sale.

(f) Any such sale or sales shall operate to divest all of the estate, right,
title, interest, claim and demand whatsoever, whether at law or in equity, of
Mortgagor in and to the properties and rights so sold, and shall be a perpetual
bar both at law and in equity against Mortgagor and any and all persons claiming
or who may claim the same, or any part thereof or any interest therein, by,
through or under Mortgagor to the fullest extent permitted by applicable law.

(g) Upon any such sale or sales, Mortgagee may bid for and acquire the Mortgaged
Property and, in lieu of paying cash therefor, may make settlement for the
purchase price by crediting against the Obligations the amount of the bid made
therefor, after deducting therefrom the reasonable expenses of the sale, the
cost of any enforcement proceeding hereunder, and any other sums which Mortgagee
is authorized to deduct under the terms hereof, to the extent necessary to
satisfy such bid.

(h) In the event that Mortgagor, or any person claiming by, through or under
Mortgagor, shall transfer or refuse or fail to surrender possession of the
Mortgaged Property after any sale thereof, then Mortgagor, or such person, shall
be deemed a tenant at sufferance of the purchaser at such sale, subject to
eviction by means of forcible entry and unlawful detainer proceedings, or
subject to any other right or remedy available hereunder or under applicable
law.

(i) Upon any such sale, it shall not be necessary for Mortgagee or any public
officer acting under execution or order of court to have present or
constructively in its possession any of the Mortgaged Property. (j) In the event
a foreclosure hereunder shall be commenced by Mortgagee, Mortgagee may at any
time before the sale of the Mortgaged Property abandon the sale, and may
institute suit for the collection of the Obligations and for the foreclosure of
this Mortgage, or in the event that Mortgagee should institute a suit for
collection of the Obligations, and for the foreclosure of this Mortgage,
Mortgagee may at any time before the entry of final judgment in said suit
dismiss the same and require Mortgagee to sell the Mortgaged Property in
accordance with the provisions of this Mortgage.

(k) This mortgage is based upon the STATUTORY CONDITION and upon the further
condition that all covenants and agreements of Mortgagor in this Mortgage, all
other instruments executed in connection therewith and in all other mortgages,
debts and obligations of or from Mortgagor to Mortgagee shall be

                                       17

Fifth: To the payment of any withholding tax requirements of the Foreign

Default shall impair such exercise, or be construed to be a waiver of any such
default or Event of Default.
