         Mortgagor represents and warrants to Mortgagee as follows:

         1.1      Warranty of Title.

         (a) Mortgagor has good and marketable title to an estate in fee simple
absolute in the Realty and Improvements and has all right, title and interest in
all other property constituting a part of the Mortgaged Property, in each case
free and clear of all liens and encumbrances, except as may otherwise be set
forth on an Exhibit B which may be attached hereto;

         (b) this Mortgage is a valid and enforceable first lien on the
Mortgaged Property (except as aforesaid) and Mortgagee shall, subject to
Mortgagor's right of possession prior to an Event of Default, quietly enjoy and
possess the Mortgaged Property; and

         (c) Mortgagor shall preserve such title as Mortgagor warrants herein
and the validity and priority of the lien hereof and shall forever warrant and
defend the same to Mortgagee against the claims of all persons and parties
whomsoever.

         1.2      Accuracy of Information.

         The information, financial statements and other financial data
furnished to Mortgagee by Mortgagor or any other obligor or guarantor of all or
any portion of the Secured Obligations, including any information furnished with
respect to the Mortgaged Property, are accurate, correct and complete in all
material respects.

         1.3      No Litigation.

         There is no litigation or governmental investigation of any type
pending, or to the best of Mortgagor's knowledge threatened, which questions the
capacity or authority of Mortgagor or any other obligor or guarantor of all or
any portion of the Secured Obligations to fulfill its obligations under this
Mortgage or the other Loan Documents, or if determined adversely, could

<PAGE>   5

materially affect the business or financial condition of Mortgagor or
Mortgagor's use, ownership, control or occupancy of any portion of the Mortgaged
Property.

         1.4      No Conflicts.

         The execution and delivery of this Mortgage and the other Loan
Documents does not conflict with any statute, rule, judgment or order of any
court or governmental authority by which Mortgagor or any other obligor or
guarantor of all or any portion of the Secured Obligations is bound and does not
conflict with or constitute a default under any contract, agreement or other
document by which Mortgagor or any such obligor or guarantor or the Mortgaged
Property is bound.

         1.5      No Casualty or Taking.

         None of the Mortgaged Property has been damaged by fire or other
casualty which is not now fully restored and no notice of taking by eminent
domain or condemnation of any of the Mortgaged Property has been received and
Mortgagor has no knowledge that any taking is contemplated.

         1.6      Licenses and Permits.

         All licenses, permits, consents and approvals necessary to occupy the
Mortgaged Property and to conduct and operate Mortgagor's business, whether at
the Mortgaged Property or elsewhere, have been obtained and are in full force
and effect, including, but not limited to, all licenses, permits, consents and
approvals required under federal, state or local law relating to occupancy,
zoning, access to public streets, sewage, stormwater drainage, building, health,
employee safety, public safety, environmental and energy matters.

         1.7      Due Organization, Etc.

         Each party (other than individuals) to each of the Loan Documents is
duly organized and validly existing under the laws of the jurisdiction of its
formation and is duly authorized and qualified to do business in each
jurisdiction wherein its activities require such authorization or qualification.
Each of the Loan Documents has been duly executed and delivered by the parties
thereto pursuant to all requisite power and authority. Each of the Loan
Documents constitutes the legal, valid and binding obligation of each of the
parties thereto, enforceable in accordance with its terms. Notwithstanding the
foregoing, Mortgagor does not make any representation or warranty as to
Mortgagee under this Section.

                            2. AFFIRMATIVE COVENANTS

or to any of the Mortgaged Property or to the use, manner of use, occupancy,
possession, operation, maintenance, alteration, repair or reconstruction of any
of the Mortgaged Property (collectively, the "Legal Requirements"), even if such
compliance necessitates structural changes or improvements or results in
interference with the use or enjoyment of any of the Mortgaged Property,
provided that no structural changes shall be made without the prior written
consent of Mortgagee.

         2.3      Impositions.

         (a) Before interest or penalties are due thereon and otherwise when

thereon, from the date of such demand at the highest rate applicable to any
portion of the Secured Obligations, but in no event exceeding the highest rate
permitted by law (the "Default Rate").

         (c) Mortgagor may in good faith contest by proper legal proceedings the
validity of any Legal Requirement or the validity or amount of any Imposition,
provided, (i) an Event of Default does not exist; (ii) Mortgagor provides
Mortgagee with security satisfactory to Mortgagee assuring compliance with or
payment of the Legal Requirement or Imposition and any additional charge,
interest, penalty, expense or other payment which may arise from or be incurred
as a result of any delay in such compliance or payment during the course of such
contest, all as estimated from time to time by Mortgagee; and (iii) such contest
operates to

of Mortgagor with Mortgagee as Mortgagee may request. Such books and records
shall be kept in all material respects in accordance with generally accepted
accounting principles consistently applied. Mortgagor shall permit Mortgagee to
photocopy such books and records on the Mortgaged Property or, if photocopying
facilities are not available on the Mortgaged Property, at a copying facility
selected by Mortgagee in its discretion. Mortgagee may freely share any of such
information with any other affiliated entity or any participating lender with
Mortgagee with respect to any part of the Secured Obligations at any time.

<PAGE>   9

         3.3      Sale of Mortgaged Property, Etc.

         Mortgagor shall not sell, assign, give, mortgage, pledge, hypothecate,

         3.4      Maintenance of Existence

         (a) If Mortgagor is other than an individual, Mortgagor will not
dissolve or liquidate nor merge or consolidate with any other entity nor permit

privileges under the laws of the state of its formation and its right to own
property and transact business in each jurisdiction where any part of the
Mortgaged Property is located.

of the Loan Agreement.

         (b) If Mortgagor shall not at any time comply with the terms of this
Section, irrespective of the passage of any grace period, Mortgagee may cure
such non-compliance and may purchase such insurance as it may elect. Mortgagor
shall reimburse Mortgagee on demand for any costs incurred by Mortgagee in
connection with any such actions, together with interest at the Default Rate.
Any such actions by Mortgagee shall not constitute a waiver of any
non-compliance of the terms of this Mortgage by Mortgagor.

         4.2      Rights of Mortgagee to Proceeds.

         In the event of any loss with respect to the project where Mortgagor is
entitled to receive insurance proceeds, Mortgagee shall have the exclusive right
to adjust, collect and compromise all such insurance claims in excess of
$250,000 (hereinafter referred to as a "Major Loss"), and Mortgagor shall not
adjust, collect or compromise any claims for Major Losses under said policies
without the prior written consent of Mortgagee. For Major Losses, each insurer
is hereby authorized and directed to make payment under said policies, including
return of unearned premiums, directly to Mortgagee instead of to Mortgagor and
Mortgagee jointly, and Mortgagor appoints Mortgagee as Mortgagor's
attorney-in-fact to endorse any draft therefor. All insurance proceeds for Major
Losses shall be payable to Mortgagee and such proceeds may, at

<PAGE>   10

Mortgagee's sole option, be applied to all or any part of the Secured
Obligations and in any order (notwithstanding that such Secured Obligations may
not then otherwise be due and payable) or to the repair and restoration of any
of the Mortgaged Property under such terms and conditions as are set forth in
Section 4.4 or otherwise as Mortgagee may impose. Mortgagee shall not be deemed
to have elected such option until such option is elected specifically in
writing. Until so elected, Mortgagee shall not in any circumstances be deemed to
have waived its right to make such election.

         4.3      Condemnation.

         Mortgagor, immediately upon obtaining knowledge of the institution of
any proceedings for the condemnation or taking by eminent domain of any of the
Mortgaged Property, shall notify Mortgagee of the pendency of such proceedings.
Mortgagee may participate in any such proceedings and Mortgagor shall deliver to
Mortgagee all instruments requested by it to permit such participation. Any
award or compensation for property taken or for damage to property not taken,
whether as a result of such proceedings or in lieu thereof, is hereby assigned
to and shall be received and collected directly by Mortgagee, and any award or
compensation shall be applied, at Mortgagee's option, to any part of the Secured
Obligations and in any order (notwithstanding that any of such Secured
Obligations may not then be due and payable) or to the repair and restoration of
any of the Mortgaged Property under such terms and conditions as are set forth
in Section 4.4 or otherwise as Mortgagee may impose. Mortgagee shall not be
deemed to have elected such option until such option is elected specifically in
writing. Until so elected, Mortgagee shall not in any circumstances be deemed to
have waived its right to make such election.

         4.4      Restoration.

         (a) All amounts received by Mortgagee pursuant to this Article and
which Mortgagee, at its sole option, permits to be applied to the restoration of
the Mortgaged Property may either be held in a restoration fund ("Restoration
Fund") by Mortgagee or, if it refuses to serve, a bank or trust company
appointed by Mortgagee which has a combined capital and surplus of not less than
$100,000,000 as restoration fund trustee (the "Restoration Fund Trustee") with
any additions thereto that may be required by Mortgagee as hereinafter provided.
The interest or income, if any, received on all deposits or investments of any
monies in the Restoration Fund shall be added to the Restoration Fund. If
Mortgagee consents to the deposit of such funds in an interest-bearing account
or otherwise consents to the investment of such funds, neither Mortgagee nor the
Restoration Fund Trustee shall be liable or accountable for any loss resulting
from any such deposit or investment or for any withdrawal, redemption or sale of
deposits or investments. Mortgagee and the Restoration Fund Trustee may impose
reasonable charges for services performed in managing the Restoration Fund and
may deduct such charges therefrom. Restoration shall be performed only in
accordance with the following conditions:

                  (i) prior to commencement of restoration and from time to time
         during restoration, Mortgagee may require Mortgagor to deposit
         additional monies into the Restoration Fund in amounts which, in
         Mortgagee's judgment, are sufficient to defray all costs to be incurred
         to complete the restoration and all costs associated therewith,
         including labor, materials, architectural and design fees and expenses
         and contractor's fees and expenses, and Mortgagee shall have approved a
         budget and cost breakdown for the restoration, together with a
         disbursement schedule, in detail satisfactory to Mortgagee;

<PAGE>   11

                  (ii) prior to commencement of restoration, the contracts,
         contractors, plans and specifications for the restoration shall have
         been approved by Mortgagee and all governmental authorities having
         jurisdiction, and Mortgagee shall be provided with satisfactory title
         insurance and acceptable surety bonds insuring satisfactory completion
         of the restoration and the payment of all subcontractors and
         materialmen;

                  (iii) all restoration work shall be done under fixed price
         contracts, fully bonded;

                  (iv) at the time of any disbursement, an Event of Default or
         any event or conditions which with the passage of time or the giving of
         notice, or both, would constitute an Event of Default shall not have
         occurred, no mechanics' or materialmen's liens shall have been filed
         and remain undischarged and an endorsement satisfactory to Mortgagee to
         its title insurance policy shall have been delivered to Mortgagee;

                  (v) disbursements from the Restoration Fund shall be made from
         time to time, but not more frequently than once each calendar month,
         for completed work under the aforesaid contracts (subject to retainage)
         and for other costs associated therewith and approved by Mortgagee upon
         receipt of evidence satisfactory to Mortgagee of the stage of
         completion and of performance of the work in a good and workmanlike
         manner in accordance with the contracts, plans and specifications as
         approved by Mortgagee;

                  (vi) Mortgagor will pay the cost of Mortgagee's inspecting
         architect or engineer and the cost of any attorney's fees and
         disbursements incurred by Mortgagee in connection with such
         restoration;

                  (vii) Mortgagee shall have the option to retain up to ten
         percent (10%) of the cost of all work until the restoration is fully
         completed, as determined by Mortgagee, and all occupancy permits
         therefor have been issued;

                  (viii) Mortgagee may impose such other reasonable conditions,
         including a restoration schedule, as are customarily imposed by
         construction lenders to assure complete and lien-free restoration;

                  (ix) any sum remaining in the Restoration Fund upon completion
         of restoration shall, at Mortgagee's option, be applied to any part of
         the Secured Obligations and in any order (notwithstanding that any of
         such Secured Obligations may not then be due and payable) or be paid to
         Mortgagor.

         (b) If within 120 days after the occurrence of any loss or damage to
the Mortgaged Property Mortgagor shall not have submitted to Mortgagee and
received Mortgagee's approval of plans and specifications for the repair,
restoration or rebuilding of such loss or damage or shall not have obtained
approval of such plans and specifications from all governmental authorities
whose approval is required or if, after such plans and specifications are
approved by Mortgagee and by all such governmental authorities, Mortgagor shall
fail to commence promptly such repair, restoration or rebuilding or if
thereafter Mortgagor fails to carry

<PAGE>   12

out diligently such repair, restoration or rebuilding or is delinquent in the
payment to mechanics, materialmen or others of the costs incurred in connection
with such work or if any other condition of this paragraph is not satisfied
within 120 days after the occurrence of any such loss or damage, then Mortgagee,
in addition to all other rights herein set forth, and after giving Mortgagor
thirty (30) days written notice of the nonfulfillment of one or more of the
foregoing conditions, may, failing Mortgagor's fulfillment of said conditions
within said thirty (30)-day period, at Mortgagee's option, (A) declare all
Secured Obligations immediately due and payable, and/or (B) perform or cause to
be performed such repair, restoration or rebuilding and may take such other
steps as Mortgagee may elect to carry out such repair, restoration or rebuilding
and may enter upon the Mortgaged Property for any of the foregoing purposes, and
Mortgagor hereby waives, for itself and all others holding under it, any claim
against Mortgagee and any receiver and their respective agents (other than a
claim based upon the alleged gross negligence or intentional misconduct of
Mortgagee or any such receiver or agent) arising out of anything done by them or
any of them pursuant to this paragraph and Mortgagee may, in its discretion,
apply any insurance or condemnation proceeds held by it to reimburse itself
and/or such receiver for all amounts expended or incurred by it in connection
with the performance of such work, including attorneys' fees, and any excess
costs shall be paid by Mortgagor to Mortgagee, and Mortgagor's obligation to pay
such excess costs shall be secured by the lien of this Mortgage and shall bear
interest at the Default Rate until paid.

         (c) Mortgagor waives any and all right to claim or recover against
Mortgagee, its officers, employees, agents and representatives for loss of or
damage to Mortgagor, the Mortgaged Property, Mortgagor's property or the
property of others under Mortgagor's control from any cause insured against or
required to be insured against by the provisions of this Mortgage.

                                   5. DEFAULT

         5.1      Events of Default.

         The occurrence of any one or more of the following events shall
constitute an "Event of Default" hereunder:

         (a) a failure to pay any Secured Obligations when due in accordance
with the terms thereof;

         (c) a failure by Mortgagor to duly perform and observe any other

thirty (30) days after notice from Mortgagee;

         (d) a failure by Mortgagor to duly perform and observe any other
provision in any of the other Loan Documents, and such failure continues beyond
the grace period, if any, set forth therein or the occurrence of any defined

understood that any such default or event of default shall be additional Events
of Default hereunder and shall not be construed to be in substitution of any
other Events of Default);


<PAGE>   13

         (e) any representation or warranty made by Mortgagor herein or in any
of the Loan Documents, or in any other instrument or document which pertains to
or is delivered in connection with any of the Secured Obligations, shall prove
to be incorrect, now or hereafter, in any material respect;

         (f) Mortgagor, or any obligor or guarantor of any of the Secured
Obligations, shall become insolvent or unable to pay its or his or her debts as
the same mature, or a petition shall be filed by Mortgagor or any such party in
bankruptcy or seeking the appointment of a receiver, trustee or conservator for

appointment of a receiver, trustee or conservator for Mortgagor or any such

to effect a plan or other arrangement with or for the benefit of creditors of
Mortgagor or any such party, and such petition shall not be dismissed within
sixty (60) days thereafter;

         (h) any attachment proceeding shall be commenced against Mortgagee or
any obligor or guarantor of any of the Secured Obligations for the collection of
any indebtedness or liability;

         (i) foreclosure proceedings shall be instituted against the Mortgaged
Property upon any other lien or claim whether alleged to be superior or junior
to the lien of this Mortgage;

         (j) the Improvements shall be substantially damaged or destroyed by an
uninsured or inadequately insured casualty;

         (k) Mortgagor shall fail to deliver any certification or other document
or instrument requested by Mortgagee pursuant to the Loan Documents within ten
(10) days after receipt of request;

         (l) Mortgagor shall fail to comply with any duty or obligation imposed
pursuant to Article 7 hereof, or any warranty or representation contained
therein shall be incorrect or misleading; or

         (m) Mortgagor shall at any time deliver or cause to be delivered to
Mortgagee a notice pursuant to 42 Pa. C.S.A. Section 8143 electing to limit the
indebtedness secured by this Mortgage.

         5.2      Demand Obligation.

<PAGE>   14

         Nothing in this Mortgage or any of the other Loan Documents shall be
construed to limit the applicability of any term of the Loan Documents providing
for the payment of any Secured Obligations on demand.

                                   6. REMEDIES

         6.1      Rights and Remedies of Mortgagee.

         If an Event of Default occurs, Mortgagee may, at its option and
notwithstanding any contrary provisions in the Loan Documents, without demand,
notice or delay, do one or more of the following:

         (a) Mortgagee may declare the entire unpaid principal balance of the
Secured Obligations, together with all interest thereon, to be due and payable
immediately (and in the case of an Event of Default under subsection 5.1(f), (g)
or (h), all such indebtedness shall automatically and immediately become due and
payable without notice or any other act).

         (b) Mortgagee may (i) institute and maintain an action of mortgage
foreclosure against the Mortgaged Property and the interests of Mortgagor
therein, (ii) institute and maintain an action on any instruments evidencing the
Secured Obligations or any portion thereof, and (iii) take such other action at
law or in equity for the enforcement of any of the Loan Documents as the law may
allow, and in each such action Mortgagee shall be entitled to all costs of suit
and attorneys' fees.

         (c) Mortgagee may, in its sole and absolute discretion, and without
releasing Mortgagor or any other obligor or guarantor from any obligation under
any of the Loan Documents and without waiving any Event of Default: (i) collect
any or all of the Rents, including any Rents past due and unpaid, (ii) perform
any obligation or exercise any right or remedy of Mortgagor under any Lease, or
(iii) enforce any obligation of any tenant of any of the Mortgaged Property.
Mortgagee may exercise any right under this subsection (c) whether or not
Mortgagee shall have entered into possession of any of the Mortgaged Property,
and nothing herein contained shall be construed as constituting Mortgagee a
"mortgagee in possession", unless Mortgagee shall have entered into and shall
continue to be in actual possession of the Mortgaged Property. Mortgagor hereby
authorizes and directs each and every present and future tenant of any of the
Mortgaged Property to pay all Rents directly to Mortgagee and to perform all
other obligations of that tenant for the direct benefit of Mortgagee, as if
Mortgagee were the landlord under the Lease with that tenant, immediately upon
receipt of a demand by Mortgagee to make such payment or perform such
obligations. Mortgagor hereby waives any right, claim or demand it may now or
hereafter have against any such tenant by reason of such payment of Rents or
performance of obligations to Mortgagee, and any such payment or performance to
Mortgagee shall discharge the obligations of the tenant to make such payment or
performance to Mortgagor. Mortgagor shall indemnify Mortgagee and hold Mortgagee
harmless from and against any and all claims, liability, damage, cost and
expense (including attorneys' fees) which may be asserted against or incurred by
Mortgagee by reason of any obligations of Mortgagor to perform any provision of
any Lease. Mortgagee may apply the Rents received by Mortgagee to the payment of
any one or more of the following, in such order and amounts as Mortgagee, in its
sole discretion, may elect, whether or not the same be then due: the Secured
Obligations, liens on any of the Mortgaged Property, Impositions, claims,
insurance premiums, other carrying charges, invoices of persons who at any time
have supplied goods or services to or for the benefit of any

<PAGE>   15

of the Mortgaged Property, and all other costs and expenses of maintenance,
repair, restoration, management, operation, ownership, use, leasing, occupancy,
protection, security, insurance, alteration or improvement of any of the
Mortgaged Property, costs of enforcing Mortgagee's rights under the Loan
Documents, including any foreclosure sale hereunder, and including all
attorneys' fees and costs. Mortgagee may, in its sole discretion, determine the
method by which, and extent to which, the Rents will be collected and
obligations of tenants enforced; and Mortgagee may waive or fail to perform or
enforce any provision of any Lease. Mortgagee shall not be accountable for any
Rents or other sums it does not actually receive. Mortgagor hereby appoints
Mortgagee as its attorney-in-fact effective upon an Event of Default to perform
all acts which Mortgagor is required or permitted to perform under any and all
Leases.

         (d) Mortgagee may, without releasing Mortgagor or any obligor or
guarantor of any of the Secured Obligations from any obligation under any of the
Loan Documents and without waiving any Event of Default, enter upon and take
possession of the Mortgaged Property or any portion thereof, with or without
legal action and by force if necessary, or have a receiver appointed without
proof of depreciation or inadequacy of the value of the Mortgaged Property, the
insolvency of Mortgagor, or any other proof. Mortgagee or said receiver may
manage and operate the Mortgaged Property, make, cancel, enforce or modify the
Leases or any of them, obtain and evict tenants, establish or change the amount
of any Rents, and perform any acts and advance any sums which Mortgagee deems
proper to protect the security of this Mortgage, all such sums to be payable on
demand, together with interest thereon at the Default Rate, from the date of
such demand, and such sums and interest to be secured by this Mortgage.

         (e) Mortgagee may take possession of the Equipment and Other Property,
or any portion thereof, and may use and deal with the same to the same extent as
Mortgagor is entitled to do so and may sell the same pursuant to law and
exercise such other rights and remedies with respect to the same as may be
provided by law, and file such continuation statements which it deems desirable.

         6.2      Sale in Parcels or Units.

         In case any sale under this Mortgage occurs by virtue of judicial
proceedings, the Mortgaged Property may be sold in one parcel or unit and as an
entity, or in such parcels or units, and in such manner or order, as Mortgagee
in its sole discretion may elect.

         6.3      Confession of Judgment in Ejectment.

         At any time after the occurrence of an Event of Default, without
further notice, regardless of whether Mortgagee has asserted any other right or
exercised any other remedy under this Mortgage or any of the other Loan
Documents, it shall be lawful for any attorney licensed in the Commonwealth of
Pennsylvania as attorney for Mortgagor to confess judgment in ejectment against
Mortgagor and all persons claiming under Mortgagor for the recovery by Mortgagee
of possession of all or any part of the Mortgaged Property, for which this
Mortgage shall be sufficient warrant. If for any reason after such action shall
have commenced the same shall be determined and the possession of the Mortgaged
Property remain in or be restored to Mortgagor, Mortgagee shall have the right
upon any subsequent default or defaults to bring one or more

<PAGE>   16

amicable action or actions as hereinbefore set forth to recover possession of
all or any part of the Mortgaged Property.

         6.4      Remedies Cumulative.

         All remedies contained in this Mortgage are cumulative and Mortgagee
also has all other remedies provided by law or in equity or in any of the other
Loan Documents. No delay or failure by Mortgagee to exercise any right or remedy
under this Mortgage will be construed to be a waiver of that right or remedy or
a waiver of any Event of Default. Mortgagee may exercise any one or more of its
rights and remedies without regard to the adequacy of its security. One or more
of the other Loan Documents may contain provisions pursuant to which all or a
part of the Secured Obligations shall become immediately and automatically due
and payable upon the occurrence of certain events described therein. Nothing in
this Mortgage shall be construed as limiting the effectiveness of such
provisions, and in the event of any inconsistency with the terms of this
Mortgage, those provisions more advantageous to Mortgagee shall govern.

         6.5      No Merger.

         (a) If Mortgagee or any other person or entity owning or holding this
Mortgage shall acquire or shall become vested with the fee title to the
Mortgaged Property or any other estate or interest in the Mortgaged Property,
such estates shall not merge as a result of such acquisition and shall remain
separate and distinct from all other estates and interests in the Mortgaged
Property for all purposes after such acquisition. The lien and security interest
created hereby shall not be destroyed or terminated by the application of the
doctrine of merger and, in such event, Mortgagee nor such other person or entity
shall continue to have and enjoy all of the rights and privileges of Mortgagee
hereunder as to each separate estate unless and until Mortgagee nor such other
person or entity shall affirmatively elect in writing to merge such estates.

         (b) Upon the foreclosure of the lien created hereby on the Mortgaged
Property, as herein provided, any Leases then existing shall not be destroyed or
terminated by application of the doctrine of merger or by operation of law or as
a result of such foreclosure unless Mortgagee or any purchaser at a foreclosure
sale shall so elect by written notice to the lessee in question.

         (c) THE OBLIGATIONS OF THE MORTGAGOR AND THE RIGHTS AND REMEDIES OF THE
MORTGAGEE HEREUNDER OR UNDER ANY OF THE LOAN DOCUMENTS OR THE SECURED
OBLIGATIONS SHALL CONTINUE AFTER AND SURVIVE THE ENTRY OF JUDGMENT HEREUNDER OR
THEREUNDER; IT BEING THE INTENTION OF THE PARTIES HERETO THAT SUCH RIGHTS,
REMEDIES AND OBLIGATIONS SHALL NOT MERGE INTO OR BE EXTINGUISHED BY ANY SUCH
JUDGMENT BUT SHALL CONTINUE UNTIL THE SECURED OBLIGATIONS HAVE BEEN IRREVOCABLY
PAID IN FULL.

                            7. ENVIRONMENTAL MATTERS

         7.1      Environmental Warranty.

<PAGE>   17

         Mortgagor hereby agrees that the Environmental Indemnity Agreement is
hereby incorporated herein by reference.

                      8. ADDITIONAL RIGHTS AND OBLIGATIONS

         8.1      Installments for Insurance, Taxes and Other Charges.

         Without limiting the effect of any other provision of this Mortgage,
Mortgagor shall, if requested by Mortgagee, pay to Mortgagee monthly with
Mortgagor's payment on the Note an amount equal to one-twelfth (1/12) of the
annual premiums for the insurance policies referred to hereinabove and the
annual Impositions and any other item which at any time may be or become a lien
upon the Mortgaged Property (the "Escrow Charges"); and on demand from time to
time Mortgagor shall pay to Mortgagee any additional sums necessary to pay when
due all Escrow Charges. The amounts so paid shall be security for the Secured
Obligations and shall be used in payment of the Escrow Charges so long as no
Event of Default shall have occurred. No amount so paid to Mortgagee shall be
deemed to be trust funds but may be commingled with general funds of Mortgagee,
nor shall any sums paid bear interest. Upon the occurrence of an Event of
Default, Mortgagee shall have the right, at its election, to apply any amount so
held against the Secured Obligations due and payable in such order as Mortgagee
may deem fit, and Mortgagor hereby grants to Mortgagee a lien upon and security
interest in such amounts for such purpose. At Mortgagee's option, Mortgagee from
time to time may waive, and after any such waiver may reinstate, the provisions
of this Section 8.1. In the event the interest of Mortgagor in the Mortgaged
Property is sold or otherwise transferred, voluntarily or involuntarily, then
all of the interest of Mortgagor in and to the sums held by Mortgagee shall vest
in the successor to the interest of Mortgagor in the Mortgaged Property,
subject, nevertheless, to the rights of Mortgagee hereunder.

         8.2      Mortgagee's Right to Protect Security.

         Mortgagee is hereby authorized to do any one or more of the following,
irrespective of whether an Event of Default has occurred: (a) appear in and
defend any action or proceeding purporting to affect the security hereof or the
rights or powers of Mortgagee hereunder; (b) take such action as Mortgagee may
determine to pay, perform or comply with any Impositions or Legal Requirements,
to cure any Events of Default and to protect its security in the Mortgaged
Property, including the recordation or filing of financing statements and other
documents to further assure the enforceability or priority of Mortgagee's liens
and security interests, advance sums on behalf of Mortgagor to pay, perform or
comply with any Imposition, Legal Requirement, prohibited lien, claims, costs
and expenses in connection with the Mortgaged Property, including payment for
utilities, fuel or any other necessary maintenance expenses, fees, insurance and
repairs; and for the purpose of exercising any such powers and all other rights
and powers granted by this Mortgage to Mortgagee, Mortgagee is hereby appointed
attorney-in-fact for Mortgagor. All sums paid by or otherwise owing to Mortgagee
under this Section shall be paid by Mortgagor to Mortgagee on demand, and until
paid such sums shall be added to the principal secured hereby, shall be included
as part of the Secured Obligations and shall bear interest at the Default Rate
from the date of demand.

         8.3      Mortgagee's Costs and Expenses.

<PAGE>   18

         In the event of an Event of Default or the exercise by Mortgagee of any
of its rights hereunder, or if Mortgagee shall become a party, either as
plaintiff or defendant or otherwise, to any suit or legal proceeding affecting
any of the Mortgaged Property or the Secured Obligations, or if review and
approval of any document, or any other matter related to any of the Secured
Obligations, is required by, or requested of, Mortgagee, Mortgagor shall pay to
Mortgagee on demand its costs, expenses and attorneys' fees incurred in
connection therewith. If such amounts are not paid, they shall be added to the
principal secured hereby, shall be included as part of the Secured Obligations
and shall bear interest at the Default Rate from the date of demand.

         8.4      Security Agreement Under Uniform Commercial Code.

         This Mortgage is a Security Agreement as defined in the Uniform
Commercial Code. Notwithstanding the filing of a financing statement covering
any of the Mortgaged Property in the records normally pertaining to personal
property, at Mortgagee's option all of the Mortgaged Property, for all purposes
and in all proceedings, legal or equitable, shall be regarded (to the extent
permitted by law) as part of the Realty, whether or not any such item is
physically attached to the Realty or Improvements. The mention in any such
financing statement of any of the Mortgaged Property shall not be construed as
in any way altering any of the rights of Mortgagee or adversely affecting the
priority of the lien granted hereby or by any other Loan Document, but such
mention in the financing statement is hereby declared to be for the protection
of Mortgagee in the event any court shall at any time hold that notice of
Mortgagee's priority of interest, to be effective against any third party, must
be filed in the Uniform Commercial Code records. This Mortgage constitutes a
fixture filing under the Uniform Commercial Code.

         8.5      Assignment of Loan Documents; Estoppel Certificates.

         Mortgagor agrees that nothing herein shall be deemed to prohibit the
assignment or negotiation, with or without recourse, of any of the Loan
Documents or any interest of Mortgagee therein, or the assignment of this
Mortgage. Mortgagor further agrees that, if requested by Mortgagee, Mortgagor
shall certify to the assignee of this Mortgage, to Mortgagee, and to such other
persons as Mortgagee may request from time to time that this Mortgage is in full
force and effect, the amount or amounts of the Secured Obligations, the terms of
the Loan Documents, whether any offsets, claims, counterclaims or defenses exist
with respect to the payment of the Secured Obligations or the performance of the
Loan Documents and such other matters as Mortgagee or any assignee may require.

         8.6      Waivers by Mortgagor.

         Mortgagor, to the extent permitted by law, hereby waives all errors and
imperfections in any proceedings instituted by Mortgagee under any of the Loan
Documents and all benefit of any present or future statute of limitation or
repose, or moratorium law, or any other present or future law, regulation or
judicial decision which (a) exempts any of the Mortgaged Property or any other
property, real or personal, or any part of the proceeds arising from any sale
thereof from attachment, levy or sale under execution, (b) provides for any stay
of execution, marshaling of assets, exemption from civil process, redemption,
extension of time for payment or valuation or appraisement of any of the
Mortgaged Property, or (c) conflicts with any provision of any of the Loan
Documents.

         8.7      Payment of Fees.


<PAGE>   19

         The Mortgagor will pay all filing, registration and recording fees, and
all expenses incident to the preparation, execution, acknowledgment, filing and
recording of this Mortgage, any financing statements, releases, continuation
statements, and any instruments of further assurance and all federal, state,
county and municipal stamp taxes and other taxes, duties, imposts, assessments
and charges arising out of or in connection with the execution and delivery of
this Mortgage and the other Loan Documents.

         8.8      Further Assurances.

         Mortgagor agrees to execute such further assurances, documents and
instruments as may be desirable by Mortgagee for the purposes of further
evidencing, carrying out and/or confirming this Mortgage and for all other
purposes intended by this Mortgage.

         8.9      Subordination to Leases.

         At the option of Mortgagee, this Mortgage shall become subject and
subordinate, in whole or in part (but not with respect to the priority of
entitlement to insurance proceeds or any award in condemnation or with respect
to any option to purchase), to any and all Leases, upon the execution by
Mortgagee and recording thereof, at any time hereafter, in the office of the
Recorder of Deeds in and for the county wherein the Realty is situate, of a
unilateral declaration to that effect.

         8.10     Subrogation.

         If the proceeds of any loan or other credit extended by Mortgagee, the
repayment of which is hereby secured, is used directly or indirectly to pay off,

the Mortgaged Property or any part thereof, then Mortgagee shall be subrogated
to any additional security held by the holder of such lien or encumbrance.

restated as of the date of each advance made or credit extended by Mortgagee
constituting a Secured Obligation.

         8.12     Acceleration.

         In order to accelerate the maturity of the indebtedness hereby secured
because of the failure of Mortgagor to pay any tax assessment, liability,
obligation or encumbrance upon the Mortgaged Property as herein provided, it
shall not be necessary that Mortgagee shall first pay the same.
