and burdening the Land; (vii) other than as shown on the survey furnished to the
Mortgagee, the Improvements are not located in an area designated as "flood
prone" (as defined under the regulations adopted under the National Flood
Insurance Program); and to the extent any of the Improvements are located (in
whole or part) in an area designated as "flood prone," the Mortgagor shall
maintain in full force and effect flood insurance under the National Flood
Insurance Program

as provided in Section 3.01; and (viii) upon request, shall promptly deliver to
the Mortgagee (A) evidence reasonably satisfactory to the Mortgagee that the
Mortgagor has complied with the provisions of this Section and (B) such other
information and documents with respect to the matters referred to in this
Section as the Mortgagee shall reasonably request.

         SECTION 2.06. PERMITTED CONTESTS. After prior notice to the Mortgagee,
the Mortgagor may contest, by appropriate proceedings conducted in good faith
and with due diligence, any Legal Requirement, any Insurance Requirement, any
Imposition or Lien therefor on the Mortgaged Property or any interest therein or
any Lien of any laborer, mechanic, materialman, supplier or vendor on the
Mortgaged Property or any interest therein, PROVIDED that (i) no Event of
Default has occurred and is continuing; (ii) no Mortgaged Property or interest
therein is in danger of being sold, forfeited or lost, nor is the priority of
the Lien of the Mortgagee at risk, as a result of such contest or proceedings;
(iii) in the case of any Legal Requirement, the Mortgagee and the other Secured
Parties are not in danger of any criminal or material civil penalty or any other
liability for failure to comply therewith and no Mortgaged Property or interest
therein is subject to the imposition of any Lien as a result of such failure
which is not properly contested in accordance with this Section; (iv) in the
case of any Insurance Requirement, no Insurance Policy or coverage is in danger
of being forfeited or lost as a result of such contest or proceedings, unless
replaced; and (v) in the case of (A) any Lien of a laborer, mechanic,
materialman, supplier or vendor, (B) any Imposition or Lien therefor or (C) any
other Lien, such proceedings suspend the foreclosure of such Lien or any other
collection thereof from the Mortgaged Property; and PROVIDED FURTHER that the
Mortgagor establishes any reserve or other appropriate provision required with
respect to such contest under generally accepted accounting principles
consistently applied. It is agreed that the failure to comply with any such
Legal Requirement or Insurance Requirement, to pay any such Imposition or to
discharge any such Lien being contested pursuant to this Section during such
contest shall not constitute an Event of Default, PROVIDED that the Mortgagor is
in compliance with this Section. Upon request, the Mortgagor shall promptly
deliver to the Mortgagee (x) a certificate of the Mortgagor describing in detail
reasonably satisfactory to the Mortgagee the contests pending as of the date
thereof and evidencing that the Mortgagor has complied with the provisions of
this Section with respect thereto and (y) such other information and documents
with respect to the contests conducted pursuant to this Section as the Mortgagee
shall reasonably request.

         SECTION 2.07. LIENS. The Mortgagor shall not create or permit to be
created and, subject to Section 2.06, within 30 days after receipt of notice or
knowledge thereof, shall discharge or cause to be discharged, any Lien on the
Mortgaged Property other than Permitted Liens, in each case (i) whether
voluntarily or involuntarily created, and (ii) whether or not subordinated
hereto. The provisions of this Section shall apply to each and every Lien (other
than Permitted Liens) on the Mortgaged Property, regardless of whether or not a
consent to, or waiver of a right to consent to, any other Lien thereon has been
previously obtained in accordance with the provisions of the Financing
Documents. Nothing herein shall obligate the Mortgagor to remove any inchoate
statutory Lien in respect of obligations not yet due and payable.

         SECTION 2.08. TRANSFER. The Mortgagor shall not Transfer, or suffer any
Transfer of, the Mortgaged Property or any part thereof or interest therein,
except in accordance with the provisions of Section 7.01(a)(i). The provisions
of this Section shall apply to each and every Transfer of the Mortgaged Property
or any interest therein, regardless of whether or not a consent to, or waiver of
a right to consent to, any other Transfer thereof has been previously obtained
in accordance with the provisions of the Financing Documents.

(a) future and present laws, ordinances, rules, regulations, orders and
requirements (including Environmental Laws) of every duly constituted
governmental or quasi-governmental authority or agency applicable to the
Mortgagor, (ii) similarly applicable orders, rules and regulations of any
regulatory, licensing, accrediting, or insurance underwriting or other body
exercising similar functions, and (iii) similarly applicable duties or
obligations of any kind imposed under any certificate of occupancy, leasehold or
otherwise by law, covenant, condition, agreement or easement, public or private,
in each case except where failure to perform and promptly comply would not
result in a material adverse affect on the Mortgaged Property.

         SECTION 2.10. ENVIRONMENTAL MATTERS. With respect to the Property, to
the best of the Mortgagor's knowledge, (a) no Hazardous Substance is now or was
formerly used, stored, generated, manufactured, installed, disposed of or
otherwise present at or about the Property or any property adjacent to the
Property (except for (i) asbestos which is being maintained in accordance with
Environmental Laws and which is to be abated, removed from the Property or
otherwise maintained in accordance with Environmental Laws and (ii) cleaning and
other products currently used in connection with the routine maintenance or
repair of such Property in full compliance with Environmental Laws), (b) all
material permits, licenses, approvals and filings required by Environmental Laws
have been obtained, and the use, operation and condition of the Property does
not, and did not previously violate any Environmental Laws to a material extent,
and (c) no civil, criminal or administrative action, suit, claim, hearing,
investigation or proceeding has been brought or been threatened, nor have any
settlements been reached by or with any parties or any liens imposed in
connection with the Property concerning Hazardous Substances or violations of
Environmental Laws.

         SECTION 2.11. COVENANTS ON ENVIRONMENTAL MATTERS. (a) The Mortgagor
shall (i) comply strictly and in all respects with applicable Environmental
Laws; (ii) notify the Mortgagee immediately upon the Mortgagor's discovery of
any spill, discharge, release or presence of any Hazardous Substance at, upon,

so as to cause the same to be in full compliance with Environmental Laws; and
(iv) promptly forward to the Mortgagee copies of all orders, notices, permits,

discharge, release or the presence of any Hazardous Substance or any other
matters relating to the Environmental Laws or any similar laws or regulations,
as they may affect the Mortgagor or the Property.

          (b) The Mortgagor shall not cause, shall use best efforts to prohibit
any other Person within its control from causing, and shall use prudent,
commercially reasonable efforts to prohibit other Persons (including tenants)
from causing (i) any spill, discharge or release, or the use, storage,
generation, manufacture, installation, or disposal, of any Hazardous Substances
at, upon, under, within or about the Property or the transportation of any
Hazardous Substances to or from such Property (except for cleaning and other
products used in connection with routine maintenance


                                       18

or repair of the Property in full compliance with Environmental Laws), (ii) the
installation of any underground storage tanks at the Property, or (iii) the
performance of any activity that requires a permit or other authorization under
Environmental Laws without prior approval by the Mortgagee, which shall not be
unreasonably withheld.

          (c) The Mortgagor shall provide to the Mortgagee, at the Mortgagor's
expense, promptly upon the written request of the Mortgagee from time to time, a
Site Assessment or, if required by the Mortgagee, an update to any existing Site
Assessment, to assess the presence or absence of any Hazardous Substances and
the potential costs associated with abatement, cleanup or removal of any
Hazardous Substances found upon, at, under or within the Property. The Mortgagor
shall pay the cost of no more than one such Site Assessment or update in any
twenty-four (24)-month period, unless the Mortgagee's request for a Site
Assessment is based upon information provided under Section 4.05 or the
Mortgagee has a reasonable suspicion that Hazardous Substances are present at,
upon, under or within the Property, any of the representations contained in
Section 2.11 are or become false, or an Event of Default shall have occurred, in
any of which cases any such Site Assessment or update shall be at the
Mortgagor's expense.

         SECTION 3.01. INSURANCE. (a) The Mortgagor shall maintain in full force
and effect the following Insurance Policies with respect to the Property (and
shall pay the Insurance Premiums for such Insurance Policies as and when due),

responsible insurance companies and be in form and substance, including the
policy limits and deductibles, approved by the Mortgagee (which approvals shall
not be unreasonably withheld):

         (i)      "all risk" property insurance in an amount not less than the
                  full replacement value of the Property and sufficient to
                  prevent the Mortgagor from being a co-insurer of any loss
                  under the policy, including difference-in-conditions coverage
                  (including boiler, machinery, sprinkler, flood and earthquake
                  coverages), and including business interruption and extra
                  expense coverages, and including, when any alteration or
                  Restoration of the Property is in progress, builder's risk
                  coverage on a completed value, non-reporting basis with
                  extended coverage and soft-cost expense coverage;

         (ii)     to the extent any of the Improvements are located (in whole or
                  part) in an area designated as "flood prone" (as defined under
                  the regulations adopted under the National Flood Insurance
                  Program), flood insurance under the National Flood Insurance
                  Program or substantially equivalent thereto in the amount

                  of not less than $80,000,000 for bodily


                                       19


<PAGE>


                  injury, death and property damage, which may be provided by
                  basic, umbrella and excess liability policies aggregating
                  said combined single limit;

         (iv)     workers' compensation and employer's liability insurance as
                  required in the State in which the Property is located or a
                  self-insurance program as permitted under applicable law in
                  the State in which the Property is located; and

         (v)      such other insurance as the Required Lenders may reasonably
                  request pursuant to Section 5.03(b)(iii) of the Credit
                  Agreement.

The physical damage insurance maintained with respect to the Property shall (i)
bear the New York standard non-contributory mortgagee endorsement (or the
equivalent thereto) naming the Mortgagee as loss payee and (ii) provide that all
property losses insured against involving a claim or claims with respect to a
single Casualty in excess of $100,000 shall be adjusted by the Mortgagor,
subject to the Mortgagee's rights pursuant to Section 3.03 hereof and the
Security Agreement. The liability insurance maintained with respect to the
Property shall name the Mortgagee and the other Secured Parties as additional
insureds. All insurance maintained by the Mortgagor with respect to the Property
shall provide that no cancellation or material change thereof shall be effective
until at least 30 days after receipt by the Mortgagee of written notice thereof
and all losses shall be payable notwithstanding any foreclosure or other action
or proceeding taken pursuant to this Mortgage.

          (b) The Mortgagor shall furnish to the Mortgagee from time to time (i)
not later than 15 days prior to the expiration date of each policy required to
be maintained by the Mortgagor hereunder, an insurance certificate or
certificates executed by the insurer or its authorized agent satisfactory to the
Mortgagee in its reasonable discretion evidencing that the new or extended
policy is in force, together with evidence satisfactory to the Mortgagee in its
reasonable discretion of the payment of the premium therefor or, if the premium
is not then due, the due date thereof, and (ii) upon Mortgagee's request, not
later than the day on which the premium for each policy required to be
maintained by the Mortgagor hereunder is due, evidence satisfactory to the
Mortgagee in its reasonable discretion of the payment of such premium. If the
Mortgagor fails to maintain the Insurance Policies required to be maintained
under this Section (or to pay the Insurance Premiums for such Insurance Policies
as and when due), the Mortgagee shall have the right (but not the obligation) to
obtain such Insurance Policies and pay the Insurance Premiums therefor. If the
Mortgagee obtains such Insurance Policies or pays the premiums therefor, upon
demand, the Mortgagor shall reimburse the Mortgagee for its reasonable expenses
in connection therewith (including reasonable attorneys' fees and expenses),
together with interest thereon from the date of demand for each day until paid
at the Post-Default Rate for Base Rate Loans.

          (c) The Mortgagor may effect such coverage under subsection (a) of
this Section under blanket insurance policies covering other properties of
the Mortgagor or its Subsidiaries, PROVIDED that (i) any such blanket
insurance policy shall specify therein, or the insurer thereunder shall
certify to the Mortgagee, (A) the maximum amount of the total insurance
afforded by the blanket policy allocated to the Property, and (B) any
sublimits in such blanket policy applicable to the Property, which sublimits
shall not be less than the amounts required pursuant to this Section, (ii)
any such blanket insurance policy shall comply in all respects with the other
provisions of this

                                       20


<PAGE>


Section and (iii) the protection afforded under any such blanket insurance
policy shall be no less than that which would have been afforded under a
separate policy relating only to the Property.

          (d) The Mortgagor shall not maintain additional or separate insurance
concurrent in form or contributing in the event of loss with the insurance
required under this Section, unless (i) the policies providing such additional
or separate insurance are submitted to the Mortgagee for its approval, which
approval shall not be unreasonably withheld, (ii) the insurers under such
policies and the terms thereof are approved by the Mortgagee, which approval
shall not be unreasonably withheld and (iii) the Mortgagee and the other Secured
Parties are included in such policies as loss payees or additional insureds.

         SECTION 3.02. CASUALTY AND CONDEMNATION. (a) The Mortgagor represents
and warrants that, as of the date hereof, except in any case as disclosed by
the Mortgagor to the Mortgagee concurrently with the execution and delivery
of this Mortgage in a writing making reference to this provision of this
Mortgage, (i) there is no Casualty or Condemnation affecting in any material
respect the use and occupancy of the Property, (ii) there are no negotiations
or proceedings presently pending in connection with a Condemnation and (iii)
to the knowledge of the Mortgagor, no Condemnation is proposed or threatened.

          (b) (i) If any Casualty occurs, the Mortgagor shall (A) immediately
take such action as may be necessary or appropriate to preserve the undamaged
portion of the Property and protect against personal injury or property
damage, and (B) promptly give notice thereof to the Mortgagee describing in
detail reasonably satisfactory to the Mortgagee the Casualty and the work and
estimated cost of Restoring the Property.

                    (ii) If any Condemnation occurs or is proposed or
threatened, the Mortgagor shall (A) promptly take all actions reasonably
necessary or appropriate to preserve its interest in the Property and (B)
promptly give notice thereof to the Mortgagee describing in detail reasonably
satisfactory to the Mortgagee the Condemnation or proposed or threatened
Condemnation and the proposed actions to preserve its interest in the
Property.

          (c) If any Casualty or Condemnation occurs, PROVIDED the applicable
Casualty Proceeds are made available to the Mortgagor, unless the Required
Lenders shall otherwise agree, the Mortgagor shall promptly commence and
diligently pursue to completion the Restoration of the Property, subject to
Unavoidable Delays, whether or not the Casualty Proceeds with respect thereto
are sufficient for such purpose; and (i) such Restoration shall be effected
with due diligence, in a good and workmanlike manner, in compliance with all
applicable Legal Requirements and Insurance Requirements, (ii) such
Restoration shall be conducted under the supervision of an architect or
engineer if customary for such Restoration, (iii) such Restoration shall be
located wholly on the Land and, except as provided for by existing easements
benefitting or burdening the Land, unless consented to by the Mortgagee and
by the owner of the other property, shall be independent of and not connected
with improvements located on other property, (iv) such Restoration shall be
promptly and fully paid for by the Mortgagor, except to the extent that any
such payment is being contested in good faith pursuant to Section 2.06, and
(v) the Mortgagor shall procure prior to the commencement of any such
Restoration, and maintain throughout the continuation of the work involved,
such insurance and performance and payment bonds as are customary for the
type of construction and work involved in Waltham, Massachusetts.

          (d) Upon request, the Mortgagor shall promptly deliver to the
Mortgagee evidence reasonably satisfactory to the Mortgagee that the
Mortgagor has complied with the provisions of this Article and such
information and documents with respect to the matters referred to in this
Article as the Mortgagee shall reasonably request.

         SECTION 3.03. CASUALTY PROCEEDS. If any Casualty or Condemnation
occurs, (i) the Mortgagor shall promptly make claim for the Casualty Proceeds
with respect thereto and diligently pursue to conclusion its claim for such
Casualty Proceeds and any suit, action or other proceeding necessary or
appropriate to obtain payment of such proceeds; and (ii) the Mortgagor shall
pay all Casualty Proceeds with respect to any Casualty or Condemnation, or
cause the same to be paid, directly and immediately to the Mortgagee for
deposit in a collateral account maintained by the Mortgagee (in its capacity
as such), to be held, applied and disbursed pursuant to provisions comparable
to those set forth in Section 12 of the Security Agreement. In the event that
there are any Casualty Proceeds in excess of the cost of Restoration as
reasonably estimated by the Mortgagee or remaining after completion and
payment of the cost of Restoration, or if the Casualty Proceeds are not
available to the Mortgagor, such excess Casualty Proceeds shall be applied
and paid by the Mortgage as provided in Section 5.06.

                                    ARTICLE 4

                           CERTAIN SECURED OBLIGATIONS

         SECTION 4.01. REVOLVING LOANS, ETC. (a) The Secured Obligations
secured by this Mortgage include, but are not limited to, (i) revolving Loans

Loans and such other Secured Obligations outstanding at any particular time,
the Mortgagor acknowledges and agrees that this Mortgage secures the total
amount of the Loans, the UK Loans and other Secured Obligations (including
the Indenture Secured Obligations) outstanding at any particular time up to
the Maximum Secured Amount.

Fourth Supplement (or another title company satisfactory to the
Administrative Agent in its reasonable discretion), or a bring-down letter
from an attorney satisfactory to the Administrative Agent in its reasonable
discretion, effective as of the last Business Day of such Fiscal Quarter or a

form and substance satisfactory to the Administrative Agent in its reasonable
discretion, evidencing whether or not any Liens or title matters have been filed

date of (x) the title commitment delivered to the Administrative Agent at the
time of the recording of this Mortgage and (y) the most recent previous title
commitment, report or letter delivered pursuant to this Section 4.01(b).

         SECTION 4.02. INTEREST AFTER DEFAULT. If, pursuant to the provisions of
this Mortgage, the Mortgagee shall make any payment on behalf of the Mortgagor
(including any payment made by the Mortgagee pursuant to Section 3.01 or 5.10)
or shall incur hereunder any expense for which the Mortgagee is entitled to
reimbursement pursuant to the provisions of this Mortgage or any other Financing
Documents, such Secured Obligation shall be repayable on demand, together with
interest from the date of demand for each day until paid at the Post-Default
Rate for Base Rate Loans. Such interest, and any other interest on the Secured
Obligations at a Post-Default Rate pursuant to the provisions of the Financing
Documents, shall accrue through the date paid notwithstanding any intervening
foreclosure, exercise of the power of sale or other sale or judgment of
foreclosure and be part of the Secured Obligations.

         SECTION 4.03. CHANGES IN THE LAWS REGARDING TAXATION. If after the date
hereof there is enacted any applicable law deducting from the value of the
Property for the purpose of taxation the Lien of any Collateral Document or
changing in any way the applicable law for the taxation of mortgages, deeds of
trust or other Liens or obligations secured thereby, or the manner of collection
of such taxes, so as to adversely affect this Mortgage, the Secured Obligations
or any Secured Party, upon demand by the Mortgagee or any other affected Secured
Party, and to the fullest extent permitted under applicable law, the Mortgagor
shall pay all taxes, assessments or other charges resulting therefrom or shall
reimburse such Secured Party, for all such taxes, assessments or other charges
which such party is obligated to pay as a result thereof.

         SECTION 4.04. INDEMNIFICATION. The Mortgagor shall protect, indemnify,
hold harmless and defend each of the Mortgagee and the other Secured Parties
(the "INDEMNIFIED PARTIES") from and against all liabilities, obligations,
losses, damages, penalties, claims, actions, suits, proceedings, judgments,
costs and expenses of any kind whatsoever (including reasonable attorneys' fees
and expenses) (collectively "CLAIMS") which may be imposed on, incurred by or
asserted against any Indemnified Party by reason of , as a result of, on account
of or in connection with (i) the Mortgagee's exercise of any of its rights and
remedies hereunder, (ii) any accident, injury to or death of persons or loss of
or damage to property occurring in, on or about the Mortgaged Property or any
part thereof or on the adjoining sidewalks, curbs, adjacent property or adjacent
parking areas, street or ways, (iii) any failure on the part of the Mortgagor to
perform or comply with any of the provisions of this Mortgage, any Legal
Requirement or any Insurance Requirement, (iv) any release or disposal on or
from the Property or presence on the Property of any Hazardous Substances, (v)
the performance of any labor or services or the furnishing of any materials or
other property in respect of the Mortgaged Property or any part thereof, and
(vi) any conduct or misconduct of the Mortgagor, any tenant or other occupant of
any of the Mortgaged Property or any of their respective agents, contractors,
subcontractors, servants, employees, licensees or invitees; PROVIDED that any
Claims caused by the willful misconduct or gross negligence of any Indemnified
Party, as determined by a court of competent jurisdiction shall be excluded from
the foregoing indemnification of such Indemnified Party, as applicable. Any
amount payable under this Section shall be payable on demand, together with
interest from the


                                       23


<PAGE>


date of demand for each day until paid at the Post-Default Rate for Base Rate
Loans. All such amounts and interest shall be part of the Secured Obligations.
The obligations of the Mortgagor under this Section shall survive the release or
termination of this Mortgage as to any matter arising out of any event occurring
prior to such release or termination.

         SECTION 4.05. ENVIRONMENTAL INDEMNITY. As between the Mortgagor and the
Secured Parties, all risk of loss associated with non-compliance with
Environmental Laws, or with the presence of any Hazardous Substance at, upon,
under or within the Property, shall lie solely with the Mortgagor. The Mortgagor
shall notify the Mortgagee promptly of the presence of any Hazardous Substance
on any property contiguous or otherwise affecting the Property. Accordingly, the
Mortgagor shall bear all risks and costs associated with any loss (including any
loss in value attributable to Hazardous Substances), damage or liability
therefrom, including all costs of removal of Hazardous Substances or other
remediation required by the Mortgagee or by law with respect to the Property.
The Mortgagor shall indemnify, defend and hold the Mortgagee and/or the Secured
Parties harmless from and against all loss, liabilities, damages, claims, costs
and expenses (including reasonable costs of defense) arising out of or
associated, in any way, with the non-compliance with Environmental Laws, or the
existence of Hazardous Substances in, on, or about the Property, or a breach by
the Mortgagor of any representation, warranty or covenant contained in this
Sections 2.11 or 2.12, whether based in contract, tort, implied or express
warranty, strict liability, criminal or civil statute or common law provided,
however, that the Mortgagor shall not be liable under such indemnification to
the extent such loss, liability, damage, claim, cost or expense results solely
from the Mortgagee's or any Secured Party's gross negligence or willful
misconduct. The Mortgagor's obligations under this Section 4.05 shall arise upon
the discovery of the presence of any Hazardous Substance, whether or not any
governmental authority has taken or threatened any action in connection with the
presence of any such Hazardous Substance, and whether or not the existence of
any such Hazardous Substance or potential liability on account thereof is
disclosed by the Site Assessment, and shall continue notwithstanding the
repayment of the Loans, the Indenture Notes and the UK Loans or any transfer or
sale of any right, title and interest in the Property (by foreclosure, deed in
lieu of foreclosure or otherwise), but not to the extent any such Hazardous
Substance was introduced to the Property after the Mortgagee or an Affiliate or
designee thereof acquires title to the Property.

         complete or partial foreclosure of this Mortgage or the complete or
         partial sale of the Mortgaged Property under the power of sale
         hereunder or under any applicable provision of applicable law; or

               (iii) to sell the Mortgaged Property, and all estate, right,
         title, interest, claim and demand of the Mortgagor therein and thereto,
         and all rights of redemption thereof, pursuant to the STATUTORY POWER
         OF SALE, at one or more sales, as an entirety or in parcels, with such
         elements of real or personal property, at such time and place and upon
         such terms as the Mortgagee may deem expedient or as may be required
         under applicable law, and in the event of a sale hereunder or under any
         applicable provision of applicable law of less than all of the
         Mortgaged Property, this Mortgage shall continue as a Lien on the
         remaining Mortgaged Property; or

                 (iv) to institute a suit, action or proceeding for the specific
         performance of any of the provisions of this Mortgage; or

         supervisor, trustee, liquidator, conservator or other custodian (a
         "RECEIVER") of the Mortgaged Property, to the fullest extent permitted
         under applicable law, as a matter of right, without notice to the
         Mortgagor, and without regard to, or the necessity to disprove, the
         adequacy of the security for the Secured Obligations or the solvency of
         the Mortgagor or any other Person obligated therefor; and the Mortgagor
         hereby, to the full extent permitted under applicable law, irrevocably
         waives such necessity and consents to such appointment of such Receiver
         without notice; and said Receiver shall be vested with the fullest
         powers permitted under applicable law, including those under subsection
         (a)(v) of this Section; or

                 (vi) to enter upon the Property, by the Mortgagee or a Receiver
         (whichever is the Person exercising the rights under this clause), and,
         to the extent permitted under applicable law, exclude the Mortgagor and
         its managers, employees, contractors, agents and other representatives
         therefrom in accordance with applicable law, without liability for
         trespass, damages or otherwise, and take possession of all other
         Mortgaged Property and all books, records and accounts relating
         thereto, and upon demand the Mortgagor shall surrender possession of
         the Property, the other Mortgaged Property and such books, records and
         accounts to the Person exercising the rights under this clause; and
         having and holding the same, the Person exercising the rights under
         this clause may use, operate, manage, preserve, control and otherwise
         deal therewith and conduct the business thereof, either personally or
         by its managers, employees, contractors, agents or other
         representatives, without interference from the Mortgagor or its
         managers, employees, contractors, agents and other representatives;
         and, upon each such entry and from time to


                                       25

         time thereafter, at the expense of the Mortgagor and the Mortgaged
         Property, without interference by the Mortgagor or its managers,
         employees, contractors, agents and other representatives, the Person
         exercising the rights under this clause may, as such Person deems
         expedient, (A) insure or reinsure the Property, (B) make all necessary
         or proper repairs, renewals, replacements, Restorations, alterations,
         additions, betterments and improvements to the Property and (C) in such
         Person's own name or, at the option of such Person, in the Mortgagor's
         name, exercise all rights, powers and privileges of the Mortgagor with
         respect to the Mortgaged Property, including the right to enter into
         Leases with respect to the Property, including Leases extending beyond
         the time of possession by the Person exercising the rights under this
         clause; and the Person exercising the rights under this clause shall
         not be liable to account for any action taken hereunder, other than for
         Rents actually received by such Person, and shall not be liable for any
         loss sustained by the Mortgagor resulting from any failure to let the
         Property or from any other act or omission of such Person, except to
         the extent such loss is caused by such Person's own willful misconduct
         or gross negligence; or

                (vii) with or, to the fullest extent permitted under applicable
         law, without entry upon the Property, in the name of the Mortgagee or a
         Receiver (whichever is the Person exercising the rights under this
         clause) or, at such Person's option, in the name of the Mortgagor, to
         collect, receive, sue for and recover all Rents and proceeds of or
         derived from the Mortgaged Property, and after deducting therefrom all
         costs, expenses and liabilities of every character incurred by the
         Person exercising the rights under this clause in collecting the same
         and in using, operating, managing, preserving and controlling the
         Mortgaged Property and otherwise in exercising the rights under
         subsection (a)(v) of this Section or any other rights hereunder,
         including all amounts necessary to pay the Impositions, the Rents, the
         Insurance Premiums and other costs, expenses and liabilities relating
         to the Property, as well as compensation for the services of such
         Person and its managers, employees, contractors, agents or other
         representatives, to apply the remainder as provided in Section 5.06; or

                (viii) to take any action with respect to any Mortgaged Property
         permitted under the UCC; or

                (ix) to take any other action, or pursue any other remedy or
         right, as the Mortgagee may have under applicable law, including the
         right to foreclosure through court action, and the Mortgagor does
         hereby grant the same to the Mortgagee.

                (b)    To the fullest extent permitted under applicable law:

                (i) each remedy or right hereunder shall be in addition to,
         and not in limitation of, any other remedy or right hereunder, under
         any Underlying Document or now or hereafter existing at law or in
         equity;

                (ii) every remedy or right hereunder, under any Underlying
         Document or under applicable law may be exercised concurrently or
         independently and whenever and as often as deemed appropriate by the
         Mortgagee or other appropriate party to the fullest extent permitted
         under applicable law;


                                       26


<PAGE>


                (iii) no failure to exercise or delay in exercising any remedy
         or right hereunder, under any Underlying Document or under applicable
         law shall be construed as a waiver of any Default or other occurrence
         hereunder or under any Underlying Document;

                 (iv) no waiver of, failure to exercise or delay in exercising
         any remedy or right hereunder, under any Underlying Document or under
         applicable law upon any Default or other occurrence hereunder or under
         any Underlying Document shall be construed as a waiver of, or otherwise
         limit the exercise of, such remedy or right upon any other or
         subsequent Default or other occurrence hereunder or under any
         Underlying Document;

                (v) no single or partial exercise of any remedy or right
         hereunder, under any Underlying Document or under applicable law upon
         any Default or other occurrence hereunder or under any Underlying
         Document shall preclude or otherwise limit the exercise of any other
         remedy or right hereunder, under any Underlying Document or under
         applicable law upon such Default or occurrence or upon any other or
         subsequent Default or other occurrence hereunder or under any
         Underlying Document;

                (vi) the acceptance by the Mortgagee or any other Secured Party
         of any payment less than the amount of the Secured Obligation in
         question shall be deemed to be an acceptance on account only and shall
         not be construed as a waiver of any Default hereunder or under any
         Underlying Document with respect thereto; and

                (vii) the acceptance by the Mortgagee or any other Secured Party
         of any payment of, or on account of, any Secured Obligation shall not
         be deemed to be a waiver of any Default or other occurrence hereunder
         or under any Underlying Document with respect to any other Secured
         Obligation.

          (c) If the Mortgagee has proceeded to enforce any remedy or right
hereunder or with respect hereto by foreclosure, sale, entry or otherwise, it
may compromise, discontinue or abandon such proceeding for any reason without
notice to the Mortgagor or any other Person (except other Secured Parties to the
extent required by the Financing Documents); and, if any such proceeding shall
be discontinued, abandoned or determined adversely for any reason, the Mortgagor
and the Mortgagee shall retain and be restored to their former positions and
rights hereunder with respect to the Mortgaged Property, subject to the Lien
hereof, except to the extent any such adverse determination specifically
provides to the contrary.

          (d) To the fullest extent permitted under applicable law, for the
purpose of carrying out any provisions of Sections 5.02(a)(vi), 5.02(a)(vii),
5.05, 5.07 or 5.10 or any other provision hereunder authorizing the Mortgagor or
any other Person to perform any action on behalf of the Mortgagor, the Mortgagor
hereby irrevocably appoints the Mortgagee, a Receiver appointed pursuant to
Section 5.02(a)(v) or any other Person designated by the Mortgagee or a Receiver
as the attorney-in-fact of the Mortgagor (with a power to substitute any other
Person in its place as such attorney-in-fact) to act in the name of the
Mortgagor or, at the option of the Person appointed


                                       27


<PAGE>


to act under this subsection, in such Person's own name, to take the action
authorized under Sections 5.02(a)(vi), 5.02(a)(vii), 5.05, 5.07 or 5.10 or such
other provision, and to execute, acknowledge and deliver any document in
connection therewith or to take any other action incidental thereto as the
Person appointed to act under this subsection shall deem appropriate in its
discretion; and the Mortgagor hereby irrevocably authorizes and directs any
other Person to rely and act on behalf of the foregoing appointment and a
certificate of the Person appointed to act under this subsection that such
Person is authorized to act under this subsection.

         SECTION 5.03. WAIVERS BY THE MORTGAGOR. To the fullest extent permitted
under applicable law, the Mortgagor shall not assert, and hereby irrevocably
waives, any right or defense the Mortgagor may have under any statute or rule of
law or equity now or hereafter in effect relating to (i) appraisement,
valuation, homestead exemption, extension, moratorium, stay, statute of
limitations, redemption, marshaling of the Mortgaged Property or the other
assets of the Mortgagor, sale of the Mortgaged Property in any order or notice
of deficiency or intention to accelerate any Secured Obligation; (ii) impairment
of any right of subrogation or reimbursement; (iii) any requirement that at any
time any action must be taken against any other Person, any portion of the
Mortgaged Property or any other asset of the Mortgagor or any other Person; (iv)
any provision barring or limiting the right of the Mortgagee to sell any
Mortgaged Property after any other sale of any other Mortgaged Property or any
other action against the Mortgagor or any other Person; (v) any provision
barring or limiting the recovery by the Mortgagee of a deficiency after any sale
of the Mortgaged Property; (vi) any other provision of applicable law (including
any provision relating to decedents' estates) which might defeat, limit or
adversely affect any right or remedy of the Mortgagee or the holders of the
Secured Obligations under or with respect to this Mortgage or the other
Collateral Documents as it relates to any Mortgaged Property; or (vii) the right
of the Mortgagee to foreclose this Mortgage in its own name as Collateral Agent
on behalf of all of the Secured Parties by judicial action as the real party in
interest without the necessity of joining any other Secured Party. Nothing in
this Section shall be construed to limit any rights, including rights to notice,
afforded to the Mortgagor under this Mortgage or the Underlying Documents.

         SECTION 5.04. JURISDICTION AND PROCESS. (a) To the fullest extent
permitted under applicable law, in any suit, action or proceeding arising out of
or relating to this Mortgage or any other Collateral Document as it relates to
any Mortgaged Property, the Mortgagor (i) irrevocably consents to the
non-exclusive jurisdiction of any state or federal court sitting in the State in
which the Property is located and irrevocably waives any defense or objection
which it may now or hereafter have to the jurisdiction of such court over, the
venue of such court for or the convenience of such court as the forum for any
such suit, action or proceeding; and (ii) irrevocably consents to the service of
(A) any process in any such suit, action or proceeding, or (B) any notice
relating to any sale, or the exercise of any other remedy by the Mortgagee
hereunder by mailing a copy of such process or notice by United States
registered or certified mail, postage prepaid, return receipt requested to the
Mortgagor at its address for notices pursuant to Section 7.03, such service to
be effective when such process or notice is mailed as aforesaid.

          (b) Nothing in this Section shall affect the right of the Mortgagee or
the Mortgagor to bring any suit, action or proceeding arising out of or relating
to this Mortgage or any other Financing Document, the Indenture or the UK
Guarantee in any court having jurisdiction under the provisions of any other
Financing Document, the Indenture or the UK Guarantee or applicable law or to
serve any process, notice of sale or other notice in any manner permitted by any
other Financing Document, the Indenture or the UK Guarantee or applicable law.

         SECTION 5.05. SALES. Except as otherwise provided herein, to the
fullest extent permitted under applicable law, at the election of the
Mortgagee, the following provisions shall apply to any sale of the Mortgaged
Property hereunder, whether made pursuant to the power of sale hereunder, any
judicial proceeding or any judgment or decree of foreclosure or sale or
otherwise:

          (a) The Mortgagee or the court officer (whichever is the Person
conducting any sale) may conduct any number of sales from time to time. The
power of sale hereunder or with respect hereto shall not be exhausted by any
sale as to any part or parcel of the Mortgaged Property which is not sold,
unless and until the Secured Obligations shall have been paid in full, and shall
not be exhausted or impaired by any sale which is not completed or is defective.
Any sale may be as a whole or in part or parcels and, to the fullest extent
permitted under applicable law, the Mortgagor hereby waives its right to direct
the order in which the Mortgaged Property or any part or parcel thereof is sold.

          (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.

          (c) After each sale, the Person conducting such sale shall execute and
deliver to the purchaser or purchasers at such sale a good and sufficient
instrument or instruments granting, conveying, assigning, transferring and
delivering all right, title and interest of the Mortgagor in and to the
Mortgaged Property sold and shall receive the proceeds of such sale up to the
Maximum Secured Amount and apply the same as provided in Section 5.06. The
Mortgagor hereby irrevocably appoints the Person conducting such sale as the
attorney-in-fact of the Mortgagor (with full power to substitute any other
Person in its place as such attorney-in-fact) to act in the name of the
Mortgagor or, at the option of the Person conducting such sale, in such Person's
own name, to make without warranty by such Person any conveyance, assignment,
transfer or delivery of the Mortgaged Property sold, and to execute, acknowledge
and deliver any instrument of conveyance, assignment, transfer or delivery or
other document in connection therewith or to take any other action incidental
thereto, as the Person conducting such sale shall deem appropriate in its
discretion; and the Mortgagor hereby irrevocably authorizes and directs any
other Person to rely and act upon the foregoing appointment and a certificate of
the Person conducting such sale that such Person is authorized to act hereunder.
Nevertheless, upon the request of such attorney-in-fact the Mortgagor shall
promptly execute, acknowledge and deliver any documentation which such
attorney-in-fact may require for the purpose of ratifying, confirming or
effectuating the powers granted hereby or any such conveyance, assignment,
transfer or delivery by such attorney-in-fact.

          (d) Any statement of fact or other recital made in any instrument
referred to in Section 5.05(c) given by the Person conducting any sale as to the
non-payment of any Secured Obligation, the occurrence of any Event of Default,
the amount of the Secured Obligations due and payable, the request to the
Mortgagee to sell, the notice of the time, place and terms of sale and the
Mortgaged Property to be sold having been duly given, the refusal, failure or
inability of the Mortgagor to act, the appointment of any substitute or
successor agent or any other act or thing having been taken or done by the
Mortgagor, the Mortgagee or any other Person shall be taken as


                                       29


<PAGE>


conclusive and binding, absent manifest error, against all other Persons as
evidence of the truth of the facts so stated or recited. The Person conducting
any sale may appoint or delegate any other Person as agent to perform any act
necessary or incident to such sale, including the posting of notices and the
conduct of such sale, but in the name and on behalf of the Person conducting
such sale.

          (e) The receipt by the Person conducting any sale of the purchase
money paid at such sale shall be sufficient discharge therefor to any purchaser
of any Mortgaged Property sold, 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 the other
Financing Documents or, in any manner whatsoever, be answerable for any loss,
misapplication or nonapplication of any such purchase money or be bound to
inquire as to the authorization, necessity, expediency or regularity of such
sale.

          (f) Subject to mandatory provisions of applicable law, any sale shall
operate to divest all of the estate, right, title, interest, claim and demand
whatsoever, whether at law or in equity, of the Mortgagor in and to the
Mortgaged Property sold, and shall be a perpetual bar both at law and in equity
against the Mortgagor and any and all Persons claiming such Mortgaged Property
or any interest therein by, through or under the Mortgagor.

          (g) At any sale, the Mortgagee may bid for and acquire the Mortgaged
Property sold and, in lieu of paying cash therefor, may make settlement for the
purchase price by causing the Secured Parties to credit against the Secured
Obligations, including the expenses of the sale and the cost of any enforcement
proceeding hereunder, the amount of the bid made therefor to the extent
necessary to satisfy such bid.

          (h) If the Mortgagor or any Person claiming by, through or under the
Mortgagor shall transfer or fail to surrender possession of the Mortgaged
Property, after the exercise by the Mortgagee or a Receiver of its remedies
under Section 5.02(a)(vi) or after any sale of the Mortgaged Property pursuant
hereto, then to the fullest extent permitted under applicable law, the Mortgagor
or such Person shall be deemed a tenant at sufferance of the purchaser at such
sale, subject to eviction by means of summary process for possession of land, or
subject to any other right or remedy available hereunder or under applicable
law.

          (i) Upon any sale, it shall not be necessary for the Person conducting
such sale to have any Mortgaged Property being sold present or constructively in
its possession.

          (j) If a sale hereunder shall be commenced by the Mortgagee, the
Mortgagee may at any time before the sale abandon the sale, and may institute
suit for the collection of the Secured Obligations or for the foreclosure of
this Mortgage; or if the Mortgagee shall institute a suit for collection of the
Secured Obligations or the foreclosure of this Mortgage, the Mortgagee may at
any time before the entry of final judgment in said suit dismiss the same and
sell the Mortgaged Property in accordance with the provisions of this Mortgage.

         SECTION 5.06. PROCEEDS. (a) Except as otherwise provided herein or
required under any mandatory provision of applicable law, the proceeds of any
sale of, or other realization upon, the Mortgaged Property hereunder up to the
Maximum Secured Amount, whether made pursuant to the power of sale hereunder,
any judicial proceeding, any judgment or decree of foreclosure or sale or
otherwise shall be paid into a collateral account maintained, by the Mortgagee
(in its capacity as such), and applied and paid as follows:

                  (i) FIRST: to the payment of all expenses of such sale or
         other realization, including compensation for the Person conducting
         such sale (which may include the Mortgagee), the cost of title
         searches, foreclosure certificates and attorneys' fees and expenses
         incurred by such Person, together with interest on any such expenses
         paid by such Person at the Post-Default Rate for Base Rate Loans from
         the date paid by such Person through the date repaid to such Person;

                 (ii)    SECOND: to the payment of the expenses and other
         amounts payable under Sections 4.04 or 7.02; and

                (iii)    THIRD: to the payment of the other Secured Obligations
         ratably (or to the provision of the payment thereof pursuant to Section
         5.06(b)) to the Secured Parties until all Secured Obligations shall
         have been paid in full;

                 (iv)    FOURTH: to pay to the Mortgagor or its successors and
         assigns, or as a court of competent jurisdiction may direct, any
         surplus then remaining from such proceeds.

          (b) If at any time any portion of any monies collected or received by
the Mortgagee would, but for the provisions of this Section 5.06(b), be payable
pursuant to Section 5.06(a) above in respect of the Unmatured UK Guaranteed
Claim, the Mortgagee shall not apply any monies to pay the Unmatured UK
Guaranteed Claim but instead shall request the UK Agent, at least ten (10)
Domestic Business Days before each proposed distribution hereunder, to notify
the Mortgagee as to the maximum amount of the Unmatured UK Guaranteed Claim if
then ascertainable. If the UK Agent does not notify the Mortgagee of the maximum
ascertainable amount thereof at least two Domestic Business Days before such
distribution, the UK Secured Parties will not be entitled to share in such
distribution. If the UK Agent does so notify the Mortgagee as to the maximum
ascertainable amount thereof, the Mortgagee will allocate to the UK Agent, for
the benefit of the UK Secured Parties, a portion of the monies to be distributed
in such distribution, calculated as if the Unmatured UK Guaranteed Claim were
outstanding in such maximum ascertainable amount. However, the Mortgagee will
not apply such portion of such monies to pay the Unmatured UK Guaranteed Claim,
but instead will hold such monies or invest such monies in such Liquid
Investments as it shall select from time to time. All such monies and Liquid
Investments and all proceeds thereof will constitute Mortgaged Property
hereunder, but will be subject to distribution in accordance with this Section
5.06(b) rather than 5.06(a). The Mortgagee will hold all such monies and Liquid
Investments and the net proceeds thereof in trust until such time as the
Unmatured UK Guaranteed Claim becomes a Matured UK Guaranteed Claim, whereupon
the Mortgagee at the request of the UK Agent will apply the amount so held in
trust to pay such Matured UK Guaranteed Claim; PROVIDED that, if the other
Secured Obligations theretofore paid pursuant to Section 5.06(a) were not paid
in full, the Mortgagee will apply the amount so held in


                                       31


<PAGE>


trust to pay the same percentage of such Matured UK Guaranteed Claim as the
percentage of such other Secured Obligations theretofore paid pursuant to
Section 5.06(a). If (A) the UK Agent shall advise the Mortgagee no portion of
the UK Guarantee Secured Obligations remains an Unmatured UK Guaranteed Claim
and (B) the Mortgagee still holds any amount held in trust pursuant to this
Section 5.06(b) (after paying all amounts payable pursuant to the preceding
sentence with respect to the Matured UK Guaranteed Claim), such remaining amount
will be applied by the Mortgagee in order of priorities set forth in Section
5.06(a).

         If at any time the Unmatured UK Guaranteed Claim shall be reduced on
account of payments made or received under the UK Credit Agreement (the amount
of such reduction being an "EXCESS AMOUNT"), and the Unmatured UK Guaranteed
Claim shall not yet have become a Matured UK Guaranteed Claim, then the amounts
required to be held in trust in accordance with this clause (ii), if any, shall
be recalculated, in accordance with the preceding paragraph, by using the value
of the Unmatured UK Guaranteed Claim as reduced by the Excess Amount instead of
the value of the Unmatured UK Guaranteed Claim immediately prior to such
reduction, and any excess monies no longer be required to be held in trust shall
be payable to the Secured Obligations other than the Unmatured UK Guaranteed
Claim in accordance with Section 5.06(a); and

          (c) In making the payments and allocations required by this Section
5.06, the Mortgagee may, (1) as to any Indenture Secured Obligations, rely upon
information from the Trustee under the Indenture and the Supplemental Indenture
and (2) as to any UK Guarantee Secured Obligations (or the amount of any Matured
or Unmatured UK Guaranteed Claim), rely upon information from the UK Agent, and
shall have no liability to the Mortgagor or any Secured Party for actions taken
in reliance on such information except in the case of its gross negligence or
wilful misconduct. All distributions made by the Mortgagee pursuant to this
Section 5.06 shall be final (except in the event of manifest error) and the
Mortgagee shall have no duty to inquire as to the application by the Secured
Parties of any amounts distributed to them.

         SECTION 5.07. ASSIGNMENT OF LEASES. (a) To the fullest extent permitted
under applicable law, subject to Section 5.07(d), the assignments of the Leases
and the Rents under Granting Clauses V and VI are and shall be present, absolute
and irrevocable assignments by the Mortgagor to the Mortgagee and, subject to
the license to the Mortgagor under Section 5.07(b), the Mortgagee or a Receiver
appointed pursuant to Section 5.02(a)(v) (whichever is the Person exercising the
rights under this Section) shall have the absolute, immediate and continuing
right to collect and receive all Rents now or hereafter, including during any
period of redemption, accruing with respect to the Property. At the request of
the Mortgagee or such Receiver, the Mortgagor shall promptly execute,
acknowledge, deliver, record, register and file any additional general
assignment of the Leases or specific assignment of any Lease which the Mortgagee
or such Receiver may require from time to time (all in form and substance
satisfactory to the Mortgagee or such Receiver) to effectuate, complete,
perfect, continue or preserve the assignments of the Leases and the Rents under
Granting Clauses V and VI.

          (b) So long as an Event of Default is not continuing, the Mortgagor
shall have a license to collect and receive all Rents (but not prior to thirty
(30) days before the due date thereof) and apply the same subject to the
provisions of the Financing Documents, such license to be terminable as provided
in Section 5.07(c).


                                       32

          (c) If an Event of Default has occurred and is continuing, the
Mortgagee or a Receiver appointed pursuant to Section 5.02(a)(v) (whichever is
the Person exercising the rights under this Section) shall have the right to
terminate the license granted under Section 5.07(b) by notice to the Mortgagor
and to exercise the rights and remedies provided under Section 5.07(a), under
Sections 5.02(a)(vi) and (vi) or under applicable law. If an Event of Default is
continuing, upon demand by the Person exercising the rights under this Section,
the Mortgagor shall promptly pay to such Person all Security Deposits under the
Leases and all Rents allocable to any period after such demand. Subject to
Sections 5.02(a)(vi) and (vi) and any applicable requirement of law, any Rents
received hereunder by such Person exercising the rights under this Section shall
be promptly paid to the Mortgagee, and any Rents received hereunder by the
Mortgagee shall be deposited in a collateral account maintained by the Mortgagee
(in its capacity as such), to be held, applied and disbursed as provided in the
Security Agreement, PROVIDED that, subject to Sections 5.02(a)(vi) and (vi) and
any mandatory requirement of applicable law, any Security Deposits actually
received by such Person shall be promptly paid to the Mortgagee, and any
Security Deposits actually received by the Mortgagee shall be held, applied and
disbursed as provided in the applicable Leases and applicable law. If after the
occurrence of an Event of Default all Events of Default shall have been fully
cured or waived as provided in the Credit Agreement, the license granted in
Section 5.07(b) shall automatically be reinstated.

          (d) Nothing herein shall be construed to be an assumption by the
Person exercising the rights under this Section, or otherwise to make such
Person liable for the performance, of any of the obligations of the Mortgagor
under the Leases, PROVIDED that such Person shall be accountable as provided in
Section 5.07(c) for any Rents or Security Deposits actually received by such
Person.

         SECTION 5.08. DEALING WITH THE MORTGAGED PROPERTY. (A) Subject to
Section 7.01, the Mortgagee shall have the right to release any portion of the
Mortgaged Property, and (B) as provided for in clause (iv) of the penultimate
paragraph preceding Article I, or in connection with any liens that are junior
and subordinate to the Liens granted hereunder, the Mortgagee shall have the
right to grant or consent to the granting of any Lien affecting any portion of
the Mortgaged Property in each of the foregoing cases, for such consideration as
the Mortgagee may require without, as to the remainder of the Mortgaged
Property, in any way impairing or affecting the Lien or priority of this
Mortgage, improving the position of any subordinate lienholder with respect
thereto or impairing or affecting the rights of any maker, guarantor, endorser,
co-maker or other obligor of the Secured Obligations, except to the extent that
the Secured Obligations shall have been reduced by any actual monetary
consideration received for such release and applied to the Secured Obligations
in accordance with Section 5.06, and may accept by assignment, pledge or
otherwise any other property in place thereof as the Mortgagee may require
without being accountable therefor to any other lienholder.

         SECTION 5.09. RIGHT OF ENTRY. The Mortgagee and its representatives
shall have the right (but not the obligation) (i) without prior notice if an
Event of Default is continuing, or (ii) with simultaneous notice, if any payment
or performance is immediately required in the reasonable opinion of the
Mortgagee to preserve the Mortgagee's right under this Mortgage or with respect
to the Mortgaged Property or (iii) after reasonable notice in all other cases,
to enter upon the Property at all reasonable times and with reasonable frequency
to inspect the Mortgaged Property or, subject to the provisions hereof, to
exercise any right, power or remedy of the Mortgagee


                                       33


<PAGE>


hereunder, PROVIDED that any Person so entering the Property shall not
unreasonably interfere with the ordinary conduct of the Mortgagor's business,
and PROVIDED FURTHER that no such entry on the Property for the purpose of
performing obligations under Section 5.10 or for any other purpose shall be
construed to be (x) possession of the Property by such Person or to constitute
such Person as a beneficiary, trustee or mortgagee in possession, unless such
Person exercises its right to take possession of the Property under Section
5.02(a)(vi), or (y) a cure of any Default or waiver of any Default or Secured
Obligation. The expense of any inspection pursuant to clause (iii) above shall
be borne by the Mortgagee unless an Event of Default shall have occurred and be
continuing at the time of such inspection, in which case the Mortgagor shall
reimburse the Mortgagee for such expense.

         SECTION 5.10. RIGHT TO PERFORM OBLIGATIONS. If the Mortgagor fails to
pay or perform any obligation of the Mortgagor hereunder, the Mortgagee and its
representatives shall have the right (but not the obligation) to pay or perform
such obligation of the Mortgagor (i) without notice, if an Event of Default is
continuing, (ii) with simultaneous notice, if such payment or performance is
immediately required in the reasonable opinion of the Mortgagee to preserve the
Mortgagee's rights under this Mortgage or with respect to the Mortgaged Property
or (iii) otherwise, after notice given reasonably in advance to allow the
Mortgagor an opportunity to pay or perform the same, PROVIDED that the Mortgagor
is not contesting such payment or performance as provided in Section 2.06, and
PROVIDED FURTHER no such payment or performance by the Mortgagee or its
representatives shall be construed to be a cure of any Default or waiver of any
Default or Secured Obligation. The Mortgagor shall reimburse the Mortgagee on
demand for its reasonable costs in connection with paying or performing any such
obligation of the Mortgagor (including reasonable attorneys' fees and expenses),
together with interest from the date of demand for each day until paid at the
Post-Default Rate for Base Rate Loans.
