in either case subject to no liens, encumbrances, easements or restrictions
other than the Permitted Encumbrances; and this Mortgage is and will remain a
valid, enforceable and perfected first lien on, and security interest in, the
Premises.

                 2.  PROVISIONS REGARDING HAZARDOUS MATERIALS.
                     ----------------------------------------

          2.1  Warranties and Representations.  The Mortgagor represents and
               ------------------------------
warrants to the Lender that, except as disclosed in the Phase I Environmental
Site Assessment Report included in Schedule 5.14 of the Loan Agreement, there
are no Hazardous Materials located in, on or under the Premises except in strict
compliance with all Hazardous Materials Legal Requirements, and that, to the
best of the Mortgagor's knowledge, there are no Hazardous Materials located in,
on or under any real property adjoining or in the vicinity of the Premises which
through soil or groundwater migration could come to be located upon or under the
Premises.

          2.2  Compliance with Laws.  The Mortgagor agrees to comply, and to
               --------------------
cause the Mortgagor to comply, duly and fully with all Hazardous Waste Legal
Requirements applicable to the Premises and agrees promptly to undertake and
diligently to pursue to completion appropriate and legally authorized remedial
containment and clean-up actions in the event of any release of any Hazardous
Material on, upon, into or under the Premises.

                                       4
<PAGE>

          2.3  Indemnification of the Lender.  The Mortgagor hereby agrees to
               -----------------------------
indemnify, defend and hold harmless the Lender from and against all loss,
liability, damage and expense, including reasonable attorneys' fees, occasioned
by or associated with (a) the Mortgagor's failure to comply duly and fully with
any Hazardous Materials Legal Requirement applicable to the Premises, (b) any
Hazardous Materials located on, upon, into or under the Premises, (c) any and
all damage to real or personal property or natural resources and/or harm or
injury to persons alleged to have resulted from any such Hazardous Materials, or
(d) the Lender's exercising in whole or in part, or failing or neglecting to
exercise, any of its rights under Section 2.4 below.

          2.4  Lender's Right to Make Site Assessments; Take Action.  The Lender
               ----------------------------------------------------
is hereby specifically authorized in its reasonable discretion to cause one or
more environmental site assessments of the Premises to be undertaken at the sole
cost and expense of the Mortgagee, at any time, and at the sole cost and expense
of Mortgagor, after the occurrence of an Event of Default.  Environmental site
assessments may include a detailed visual inspection of the Premises, including,
without limitation, all storage areas, storage tanks, drains, drywells and
leaching areas, as well as the making of ground borings and the taking of soil
samples, surface water samples and groundwater samples, and such other
investigations or analysis as is necessary or appropriate for a complete
assessment of the compliance of the Premises and the use and operation thereof
with all Hazardous Materials Legal Requirements.  Without limiting the
foregoing, in the event that there shall occur a release of Hazardous Materials
on, upon, into or under the Premises, or such a release appears imminent or
probable, the Lender shall have the right (but not the obligation), upon prior
notice to the Mortgagor (or without notice in the case of emergency), to cause
the release to be contained and/or removed on behalf of the Mortgagor or to
attempt to prevent or contain such a release.  The Mortgagor agrees to cooperate
with the Lender and to render such assistance to the Lender as may be requested
to facilitate such remedial actions (including, without limitation, such
containment or removal).  The Mortgagor shall be liable to the Lender for all
costs and expenses, including reasonable attorneys' fees, incurred on account of
such remedial action undertaken on the Mortgagor's behalf and shall reimburse
the Lender therefor on demand, and such costs shall be deemed included in the
Obligations.

          2.5  Survival of the Mortgagor's Obligations.  All of the Mortgagor's
               ---------------------------------------
obligations owed to the Lender under this Article 2, including, without
limitation, the indemnification obligation set forth in Section 2.3 above, shall
survive the payment of the Loan Documents and the discharge of this Mortgage in
all respects.  It is the intent of this Article 2 that the Lender shall at all
times remain fully indemnified and protected by the Mortgagor from any and all
liability which the Lender might incur as a result of the Mortgagor's failure to
comply duly and fully with any Hazardous Materials Legal Requirement applicable
to the Premises or otherwise arising from any Hazardous Materials on the
Premises which existed on, or were introduced to, the Premises during the term
of the Mortgagor's ownership thereof.

                        3.  COVENANTS OF THE MORTGAGOR.
                            --------------------------

          3.1  Construction and Completion of Improvements.  All buildings,
               -------------------------------------------
structures and other improvements hereafter constructed on the Premises shall be
completed by the

                                       5
<PAGE>

Mortgagor in a good and workmanlike manner, in accordance with all applicable
governmental laws, statutes, ordinances, by-laws, codes, rules, regulations and
requirements, and approved in advance and in writing by the Lender, which
approval shall not be unreasonably withheld or delayed as to non-structural
improvements, and otherwise in accordance with the provisions of the Loan
Documents. Notwithstanding the foregoing, Mortgagor may from time to time make
alterations, additions or improvements to the Premises, without the approval of
Lender, provided: (i) the cost thereof shall not exceed Thirty Thousand Dollars
($30,000) in the aggregate in any consecutive twelve-month period; (ii)
Mortgagor shall, prior to commencing any such alterations, additions and/or
improvements or approving any lessee alterations, additions, or improvements in
the Premises in connection therewith, furnish Lender with a complete set of
plans and specifications for any such alterations, additions and/or
improvements; and (iii) such alterations, additions and/or improvements shall
not involve or affect the exterior or the structure of the Building or any of
the mechanical, electrical or plumbing systems of the Building.

          3.2  Prohibition Against Encumbrances; Restrictions on Transfer.  (a)
               ----------------------------------------------------------
The Mortgagor shall not, directly or indirectly, permit or suffer to be created
or to remain, and shall discharge, or promptly cause to be discharged, any
mortgage, lien, attachment, or other encumbrance on the Premises or any part
thereof or interest therein, other than the Loan Documents and Permitted
Encumbrances.  The Mortgagor shall promptly give the Lender notice of and,
unless the Lender requests otherwise, appear in and diligently contest at the
Mortgagor's sole cost and expense, any action or proceeding which purports to
affect the Mortgagor's title to the Premises or the priority or validity of this
Mortgage.

               (b)  Except for the Permitted Encumbrances, the Mortgagor shall
not, directly or indirectly, without the prior written consent of Lender in each
instance obtained, which consent may be withheld in Lender's sole discretion,
convey, sell, assign, transfer, dispose of (or permit any conveyance, sale,
assignment, transfer or disposition, whether voluntary or involuntary, of)
ownership or control of all or any part of any legal or beneficial interest in:
(i) the Premises or any part thereof (including any grant of a mortgage, other
lien or security interest in any legal or beneficial interest in the Premises or
any part thereof, or any sale, assignment, transfer or disposition of any rents
and other contractual claims), or (ii) the Mortgagor (collectively or
individually, a "Transfer"). Any sale or transfer (or cumulative sales or
transfers) of the capital stock of the Mortgagor in excess of 25% shall
constitute a transfer; provided, however, such sale or transfer of capital stock
shall not be deemed a transfer so long as Mortgagor is an entity whose
outstanding stock is listed on a recognized security exchange.

          3.3  Operation of Premises.  (a) The Mortgagor shall make such repairs
               ---------------------
and replacements and take such other steps as may be necessary to keep and
maintain the Premises in compliance with all Legal Requirements and in at least
as good repair, order and condition as the same now are or hereafter may be put
while this Mortgage is outstanding, excepting only deterioration incidental to
reasonable wear and use and any Taking; it being understood, however, that the
foregoing exception for reasonable wear and use shall not relieve the Mortgagor
from the obligation to repair or replace worn out, inoperative or otherwise
deficient elements of the Premises.

                                       6
<PAGE>

               (b)  The Mortgagor shall not (except as otherwise expressly
permitted in this Mortgage or otherwise consented to in advance and in writing
by the Lender) permit or suffer the removal, demolition or any other waste of
any of the Premises, except that nothing in this Mortgage shall be deemed to
prevent replacements or substitutions for items constituting part of the
Collateral where such replacements and substitutions are comparable as to
function, quality and value.

               (c)  The Mortgagor shall fully and seasonably keep, observe and
satisfy all federal, regional, state and local laws, statutes, ordinances,
by-laws, codes, rules and regulations applicable to the Premises or the
occupancy or use thereof.

               (d)  The Mortgagor shall not make or permit any structural or
nonstructural alterations, improvements or additions to the Premises, except as
permitted in Section 3.1.

               (e)  The Mortgagor shall permit the Lender and its authorized
representatives to enter and examine the Premises from time to time, at all
reasonable times, in accordance with the terms of each lessee's lease and
without unreasonable interference with lessees' use and occupancy of the
Premises.

          3.4  Payments.  (a) The Mortgagor shall pay or cause to be paid,
               --------
promptly when due:  (i) all taxes, betterments, assessments and other
governmental levies, water rates, sewer charges, insurance premiums and other
charges, to whomever and whenever laid or assessed, whether on the Premises,
this Mortgage, any of the other Loan Documents or on any interest therein, or
any other debt or obligation expressly secured hereby (collectively, the
"Impositions"); and (ii) all federal, state and other taxes of whatever kind and
nature which could, if unpaid, result in a lien on the Premises or on any
interest therein.  Mortgagor may contest the validity or amount of such
Impositions, provided that: (i) the non-payment thereof does not pose a threat
of loss or seizure of the Building or interest of Mortgagor or Lender therein or
impose any fee or penalty against Mortgagor; (ii) Mortgagor notifies Lender of
such contest and thereafter diligently proceeds with such contest in accordance
with Law; and (iii) Lender may require Mortgagor to post a bond or other
collateral reasonably satisfactory to Lender in connection with such action.

               (b)  At any time following an Event of Default, if requested in
writing by the Lender, the Mortgagor shall deposit with the Lender, on a monthly
basis (each of which dates is hereinafter referred to as a "Monthly Tax Deposit
Date") until the payment in full of the Obligations, a sum equal to one-twelfth
(1/12) of the Impositions to be levied, charged, filed, assessed or imposed upon
or against the Premises and/or the Collateral within one (1) year after said
Monthly Tax Deposit Date.  If the amount of the Impositions to be levied,
charged, assessed or imposed within the ensuing one (1) year period shall not be
fixed upon any Monthly Tax Deposit Date, such amount for the purpose of
computing the tax deposit to be made by the Mortgagor hereunder shall be
estimated by the Lender, with an appropriate adjustment to be promptly made
between the Mortgagor and the Lender as soon as the fixed amount of such
Impositions is determinable.

                                       7
<PAGE>

     The sums deposited by the Mortgagor under this Section 3.4(b) shall be held
by the Lender and shall be applied in payment of the Impositions when due.  Such
deposits shall not be commingled with other assets of the Lender except for
other real estate tax escrows in connection with other properties, and shall be
held in trust in an account at a recognized financial institution selected by
the Lender.  The Mortgagor shall give twenty (20) days' prior written notice to
the Lender in each instance when an Imposition is due, specifying the Imposition
to be paid and the amount thereof, the place of payment and the last day on
which the same may be paid.

     If for any reason the sums on deposit with the Lender under this Section
3.4(b) shall not be sufficient to pay an Imposition not later than thirty (30)
days before the last day on which the same may be paid without penalty or
interest, then, within ten (10) days after demand by the Lender, the Mortgagor
shall deposit sufficient sums so that the Lender may pay such Imposition in
full, together with any penalty and interest thereon.  The Lender may change its
estimate of any Imposition for any period on the basis of a change in an
assessment or tax rate or on the basis of a prior miscalculation or for any
other reason; in which event, within ten (10) days after demand by the Lender,
the Mortgagor shall deposit with the Lender the amount in excess of the sums
actually deposited which would theretofore have been payable under the revised
estimate.

     If any Imposition shall be levied, charged, filed, assessed or imposed upon
or against the Premises and/or the Collateral and if such Imposition shall also
be a levy, charge, assessment or imposition upon or for any other real or
personal property not covered by the lien of this Mortgage, then the computation
of the amounts to be deposited under this Section 3.4(b) shall be based upon the
entire amount of such Imposition and the Mortgagor shall not have the right to
apportion any deposit with respect to such Imposition.

     Upon an assignment of this Mortgage by the Lender, the Lender shall have
the right to transfer all amounts deposited pursuant to the provisions of this
Section 3.4(b) and still in its possession to such assignee (as the subsequent
holder of this Mortgage) which agrees to hold such funds in accordance with the
foregoing terms, and the original Lender named herein shall thereupon be
completely released from all liability with respect to such tax deposits and the
Mortgagor shall look solely to said assignee (as the subsequent holder of this
Mortgage) in reference thereto.

     All amounts deposited with the Lender pursuant to the provisions of this
Section 3.4(b) shall be held by the Lender as additional security for the sums
secured by this Mortgage and upon the occurrence of any Event of Default
hereunder the Lender may, in its sole and absolute discretion, apply said
amounts toward payment of the Obligations.  Upon the complete payment and
performance of the Obligations, any sums then held by the Lender under this
Section 3.4(b) shall be refunded to the Mortgagor.

     At the option of the Lender, after request therefor, the Mortgagor shall
deliver to the Lender copies of all notices, demands, claims, bills and receipts
in relation to the Impositions immediately upon the receipt thereof by the
Mortgagor.

          3.5  Copies of Notices to Lender.  The Mortgagor shall deliver to the
               ---------------------------
Lender promptly upon receipt of the same, copies of all notices, certificates,
documents and instruments

                                       8
<PAGE>

received by the Mortgagor from any agency or authority having jurisdiction over
the Premises, or any insurer of the Premises, which materially affect the
Premises or its occupancy or use.

          3.6  Intentionally Omitted.
               ----------------------

          3.7  Appraisals.  The Mortgagor agrees that the Lender shall have the
               ----------
right, not more than once per year, at any time so long as the Loan remains
outstanding, to order an appraisal or appraisals of the Premises if reasonably
required by the Lender to administer the Loan or required of the Lender by any
regulatory agency or authority having jurisdiction over the Lender, the
reasonable cost of which shall be paid by Mortgagor.

                4.  SECURITY AGREEMENT COVERING THE COLLATERAL.
                    ------------------------------------------

     4.1  Financing Statements; Further Assurances.  Subject to the terms of the
          ----------------------------------------
Loan Documents, the Mortgagor hereby covenants and agrees with the Lender that
as of the execution hereof and hereafter from time to time when requested by the
Lender, the Mortgagor shall (a) duly execute and deliver to the Lender, in form
appropriate for recording and filing, a security agreement and/or financing
statement or statements relating to the Collateral or any part thereof, it being
further agreed that the Lender may record or file a carbon, photographic or
other reproduction of a financing statement or this Mortgage in lieu of any
originally signed financing statement or statements; and (b) provide to the
Lender such other assurances as may be required by the Lender to establish,
preserve, perfect and protect the Lender's first and prior security interest in
the Collateral.

     4.2  Warranties; Representations; Covenants.  The Mortgagor hereby
          --------------------------------------
represents and warrants to, and covenants and agrees with, the Lender that (a)
the Collateral is and shall be used primarily for business purposes and is not
and shall not be bought, leased or used primarily for personal, family or
household purposes, and (b) except for Permitted Encumbrances, no financing
statement, security agreement or other lien instrument covering all or any part
of the Collateral or any proceeds thereof is on file in any public office.

     4.3  Procedure for Sale.  The Mortgagor hereby agrees that whenever
          ------------------
notification with respect to the sale or other disposition of the Collateral
(including collateral in which the Lender has been granted a security interest
pursuant to the Loan Documents) is required by law, such notification of the
time and place of public sale, or of the date after which a private sale or
other intended disposition is to be made, shall be deemed reasonable if given at
least ten (10) days before the time of such public sale or the date after which
any such private sale or other intended disposition is to be made, as the case
may be.  Further, the Lender shall be authorized and permitted to entirely or
partially postpone, adjourn, continue and reschedule any such sale, once or
several times, and entirely or partially all without prejudice or breach of any
duty or obligation of the Lender.

                   5.  EMINENT DOMAIN; APPLICATION OF AWARD.
                       ------------------------------------

     In case of any Taking of all or any part of the Premises or the
commencement of any proceedings or negotiations which might result in a Taking,
the Mortgagor shall promptly give

                                       9
<PAGE>

written notice thereof to the Lender, generally describing the nature and extent
of the Taking and any proceedings or negotiations regarding the Taking. The
Lender may, at its option, appear in any proceeding in connection with, or any
negotiations relating to, a Taking and the Mortgagor shall promptly give to the
Lender copies of all notices, pleadings, determinations and other papers in any
such proceedings or negotiations. The Mortgagor shall in good faith and with due
diligence and counsel reasonably satisfactory to the Lender file and prosecute
the Mortgagor's claim or claims for any award or payment on account of any
Taking of the Premises; and if the Mortgagor does not so prosecute its claim,
then the Lender, in its reasonable judgment, shall have the right to file and
prosecute such claim at the Mortgagor's sole cost and expense. The Mortgagor
shall not settle any such claim or claims for less than the Secured Debt without
the Lender's prior written consent which consent shall not be unreasonably
withheld or delayed. The Mortgagor hereby assigns to the Lender all of the
Mortgagor's right, title and interest in and to any claim to damages or to
participation in any award in connection with a Taking and hereby irrevocably
authorizes such awards to be paid directly to the Lender. If the Mortgagor
collects any such claim or claims, by settlement, judicial decree or otherwise,
the Mortgagor shall promptly pay the same to the Lender. Any such awards, after
deducting therefrom all costs and expenses, including reasonable attorneys'
fees, incurred by the Lender in connection therewith, shall be applied by the
Lender in accordance with the provisions of Section 6.6 below.

                           6.  INSURANCE; CASUALTY.
                               -------------------

          6.1  Coverage.  The Mortgagor shall, at the Mortgagor's sole cost and
               --------
expense, obtain and keep in force while this Mortgage is on record, the
following insurance coverage: (a) casualty insurance in amounts reasonably
required by the Lender against all risks of physical loss, covering the
improvements from time to time constituting a part of the Premises and
equipment, supplies and materials furnished, with such deductibles as the Lender
may approve; (b) comprehensive public liability insurance in such amounts (which
amounts shall not be less than $1,000,000.00) and covering such matters as are
reasonably satisfactory to the Lender; (c) worker's compensation insurance
(including employer's liability insurance, if requested by the Lender) for all
employees of the Mortgagor engaged on or with respect to the Premises in such
amounts as are reasonably satisfactory to the Lender, but not less than such
amounts as may from time to time be established by law; and (d) such other
insurance coverages in such amounts and such additional amounts for existing
coverages as may from time to time, in light of requirements of mortgagees of
similar premises, be reasonably required by the Lender.

          6.2  Certain Policy Provisions.  The policies of insurance provided
               -------------------------
for in Sections 6.1 shall designate the Lender as an additional insured as to
the Premises and shall provide that the Lender is the mortgagee and loss payee
thereunder and that any proceeds shall be payable to the Lender, as its
interests may appear, pursuant to a standard mortgagee endorsement.  All such
policies issued by the respective insurers shall provide that the loss, if any,
thereunder shall be adjusted and paid as provided in this Mortgage.  All
policies of insurance provided for in this Article 6 shall also provide:  (a)
that such policies shall not be cancelled or amended without at least thirty
(30) days' prior written notice to the Lender; (b) that any amount payable due
to loss shall be payable to the Lender, notwithstanding any act or omission or
negligence of the Mortgagor which might otherwise result in forfeiture of, or

                                       10
<PAGE>

defense of a claim under, said insurance; and (c) that the insurer waives all
rights of set off, counterclaim or deduction against the Mortgagor.

          6.3  Carriers; Evidence of Insurance.  All insurance provided for in
               -------------------------------
this Article 6 shall be effected with insurers approved in advance and in
writing by the Lender.  Upon delivery hereof, and thereafter, not less than
fifteen (15) days prior to the expiration dates of the expiring policies,
originals of the policies provided for in this Article 6, in form and content
satisfactory to the Lender, shall be delivered by the Mortgagor to the Lender.

          6.4  Assignment of Policies Upon Foreclosure.  In the event of
               ---------------------------------------
foreclosure of the Mortgage or other transfer of title or assignment of the
Premises, in whole or in part, all right, title and interest of the Mortgagor in
and to all policies of insurance required by this Article 6 above shall
automatically inure to the benefit of, and pass to, the Lender or the Lender's
successor in interest or the purchaser or grantee of the Premises.

          6.5  Fulfillment of Conditions and Prosecution of Claims.  The
               ---------------------------------------------------
Mortgagor shall perform, observe and keep all the conditions of all insurance
policies covering the Premises and, in case of any loss or damage or claim, the
Mortgagor shall forthwith give immediate notice by mail to the Lender.  The
Mortgagor shall in good faith and with due diligence and counsel satisfactory to
the Lender prosecute any claim or claims relating to such loss or damage; and if
the Mortgagor does not so prosecute its claim, then the Lender shall have the
right to file and prosecute such claim at the Mortgagor's sole cost and expense.
Each insurance company is hereby authorized and directed to make payment for
such loss directly to the Lender instead of to the Mortgagor.  If in fact, the
Mortgagor in good faith and diligently prosecutes such claim, then such claim
shall be adjusted by the Mortgagor only but with the prior written consent of
the Lender, such consent not to be unreasonably withheld or delayed.  The
insurance proceeds for each such loss or damage, after deducting all costs and
expenses, including reasonable attorneys' fees incurred by the Lender in
connection therewith, under any policy provided for in this Section 6, shall be
paid to the Lender, and shall be applied by the Lender in accordance with
Section 6.6. below.  Except to the extent insurance proceeds are actually
retained by the Lender and applied to the Obligations, nothing herein shall be
deemed to relieve the Mortgagor from the obligation to maintain and repair the
Premises and to restore the Premises from all damage and destruction, regardless
of whether or not sufficient proceeds are available.  Further, such retention
and application shall be deemed a cure or waiver of any Event of Default under
this Mortgage.

          6.6  Application of Proceeds.  Subject to the terms and conditions of
               -----------------------
the Loan Documents, all proceeds received by the Lender with respect to a taking
of the Premises and all insurance proceeds with respect to fire or other insured
casualty, shall be applied as follows, in the order of priority indicated:

               (a) to reimburse the Lender for any costs and expenses, including
               reasonable attorneys' fees, incurred in connection with
               collecting said proceeds;

                                       11
<PAGE>

               (b) to the payment of all unpaid interest accrued on the Loan
               Documents;

               (c) to reimburse the Mortgagor for any reasonable costs and
               expenses, including reasonable attorneys' fees, incurred in
               connection with collecting said proceeds;

               (d) to the prepayment of the unpaid principal balance of the Loan
               Documents, without premium; and

               (e) to the Mortgagor or to such other person as may be entitled
               to receive the same;

provided however, that subject to the terms and conditions of the Loan
Documents, in the event of a taking of less than the entire Premises or in the
case of fire or other insured casualty which destroys less than all or
substantially all of the Premises, the Lender shall apply the proceeds first in
accordance with clause (a) of this Section until reimbursed in full and, if and
so long as (1) the Lender determines, in the reasonable exercise of its
discretion, that the restoration, replacement and rebuilding of the Premises can
be accomplished with available proceeds (or if such proceeds are not adequate
for repair, the Mortgagor agrees to supplement such proceeds with its own funds
so that adequate funds are available for repair), (2) the leases, if any,
affecting the Premises will continue in force and effect throughout, and at the
completion of, such restoration, replacement or rebuilding, and (3) no Event of
Default exists, the Lender shall apply the proceeds first in accordance with
clause (a) of this paragraph until reimbursed in full, then to the restoration,
replacement and rebuilding of the Premises, with advances of such proceeds being
made on a customary construction lending basis, until completion of such
restoration, repair or replacement and then in accordance with (b), (c), (d) and
(e) of this Section in that order of priority.

                    7.  RIGHTS AND REMEDIES OF THE LENDER.
                        ---------------------------------

          7.1  Rights Exercisable Regardless of Default.  Whether or not an
               ----------------------------------------
Event of Default (defined in Section 7.3 below) or any event which, with the
giving of notice or the passage of time or both would constitute an Event of
Default, exists under this Mortgage, the Lender shall have the following rights:

               (a)  The Lender is hereby specifically authorized to make, at the
Lender's sole option, any or all payments required to be made either hereunder,
or otherwise by the Mortgagor in connection with the Premises or any of the
transactions contemplated by the Loan Documents.  Such payments may include, but
are not limited to, payments for taxes, assessments, betterments and other
governmental levies, and charges, water rates, insurance premiums, maintenance,
repairs or improvements constituting a part of the Premises.  The Lender shall
have the right, but not the duty, to perform any obligations of the Mortgagor
relating to the Premises, without waiving any other rights or releasing the
Mortgagor from any obligation hereunder.

                                       12
<PAGE>

               (b)  The Lender shall have the right, but not the duty, to
intervene or otherwise participate in any legal or equitable proceeding which,
in the Lender's reasonable judgment, affects the Premises or any of the rights
created or secured by any of the Loan Documents. Such rights may be exercised by
the Lender at any time, but only after notice to the Mortgagor, and only to the
extent permitted by law and necessary to protect its rights hereunder and in the
Premises, and shall be at its sole expense prior to the occurrence of any Event
of Default, and at Mortgagor's cost and expense subsequent to the occurrence of
an Event of Default.

          7.2  Effect of Exercise of Rights.  Any sums paid, and any costs or
               ----------------------------
expenses, including reasonable attorneys' fees reasonably incurred by the
Lender, pursuant to the Lender's exercise of rights specified or referred to
herein or any of the Loan Documents, shall as between the parties hereto and
their successors-in-interest, be deemed valid, so that in no event shall the
necessity or validity of any such payments, costs or expenses be disputed.

          7.3  Events of Default.  The occurrence of any one or more of the
               -----------------
following events (each, an "Event of Default") shall constitute a default under
and breach of this Mortgage: (a) an Event of Default under the Loan Agreement,
(b) any breach of Sections 3.2(b) or 3.4 of this Mortgage, or (c) any breach of
any other provision of this Mortgage that is not cured within thirty (30) days
after written notice from Lender but, in the event the breach is not capable of
cure within such thirty (30) day period, it shall be an Event of Default only if
Mortgagor fails to commence to cure such breach within such thirty (30) day
period and diligently prosecute such cure to completion thereafter.

          7.4  Remedies; Rights and Remedies Cumulative.  Upon the occurrence of
               ----------------------------------------
any Event of Default, the Lender may at any time thereafter, at its option and
without notice exercise any or all of the following rights and remedies in
addition to (and not in limitation of) any and all other rights or remedies
available to it under applicable law as a mortgagee/secured party: (a) declare
all of the Obligations due and payable, and the Obligations shall thereupon
become and be immediately due and payable, anything in any of the Loan Documents
to the contrary notwithstanding, provided that, notwithstanding and without
limiting the generality of the foregoing, upon the occurrence of an Event of
Default under Section 7.3 hereof, all of the Obligations automatically shall
become and be immediately so due and payable; (b) apply to the Obligations any
deposits or other sums credited by or due from the Lender to the Mortgagor
including, without limitation, funds held in any real estate tax or other escrow
account held by or on behalf of the Lender (without first enforcing any other
rights of the Lender against the Mortgagor or any endorser of the Loan Documents
or any Guarantor, or against the Premises); (c) exercise any and all of the
rights and remedies of a secured party under the Uniform Commercial Code; (d)
appoint or cause to be appointed a receiver or custodian of the Premises, with
or without commencing foreclosure of this Mortgage or suit on the Loan Documents
or to otherwise collect on the Obligations, and without regard for the adequacy
of the security for the Obligations, and such receiver shall be authorized to
enter upon and take and maintain full control of the Premises in order to
perform all acts necessary or appropriate for the operation and maintenance
thereof, including but not limited to, the execution, cancellation or
modification of leases, the collection of all rents and revenues of the
Premises, the making of repairs to the Premises and the execution or termination
of contracts providing for the management or

                                       13
<PAGE>

maintenance of the Premises, all on such terms as are deemed best to protect the
security of this Mortgage; (e) foreclose upon this mortgage by judicial
proceeding or any other manner permitted by applicable law, and such rights
shall not be exhausted until all of the Premises shall have been sold or all
other Obligations satisfied; (f) take such other actions or proceedings as the
Lender deems necessary or advisable to collect or enforce or to protect its
interest in the Premises and the Obligations; and (g) exercise of such other
rights and remedies as may be available to a mortgagee/secured party under
applicable law. Such options shall continue until all such Events of Default
have been cured, and may be exercised individually, sequentially or in concert,
all such remedies being cumulative, the exercise of one not being deemed a
waiver of any of the others or a cure of any Event of Default. Furthermore, if
the Lender commences any action to foreclose this Mortgage, the Lender may
postpone such foreclosure sale of all or any parcel of the Premises by public
announcement at the time and place of any previously scheduled sale, and the
Lender shall be entitled to postpone, adjourn and reschedule and/or cancel any
such sale in its sole discretion without prejudice, and without it being deemed
commercially unreasonable. Lender shall be entitled to collect all expenses
incurred in pursuing any right or remedy following an Event of Default,
including, but not limited to, reasonable attorneys' fees (which fees shall be
allowed and paid as part of the decree of judgment) and costs of title evidence.
The proceeds of any such sale shall be applied in the following order: (i) all
costs and expenses of the sale, including reasonable attorneys' fees, title
examination costs, advertising costs, auctioneer's costs and the like; (ii) to
all unpaid interest secured by this Mortgage; (iii) to all unpaid principal and
other unpaid sums secured by this Mortgage; and (iv) the excess, if any, to the
person or persons legally entitled thereto.

          7.5  Rents; Mortgagee in Possession; Etc.  Upon the occurrence of any
               -----------------------------------
Event of Default, the Lender, without in any way waiving any rights under this
Article 7, may at its option, without notice, and without regard to the adequacy
of the security for the indebtedness secured hereby, either in person or by
agent, with or without bringing any action or proceeding to foreclose this
Mortgage, bringing any suit on the Loan Documents or otherwise to collect the
Obligations, or by a receiver appointed by a court, take possession of the
Premises, hold, manage, lease and operate the same on such terms and for such
period of time as the Lender may deem proper and, either with or without taking
possession of the Premises, and with or without initiating foreclosure
proceedings, in the name of the Mortgagor or in its own name as Assignee,
demand, sue for or otherwise collect and receive all rents, income and profits
of the Premises, including those past due and unpaid.  All rents collected by
the Lender shall be applied first to the payment of costs of management of the
Premises and collection of rents, including, but not limited to, reasonable
attorneys' fees, and then to the sum secured by this Mortgage.  The Lender shall
be liable to account only for those rents actually received, and shall not be
liable for any mismanagement or other conduct in connection with its possession,
management or operation of the Premises, except for its willful misconduct or
gross negligence.  If the rents of the Premises are not sufficient to meet the
costs, if any, of taking control of, operating and managing the Premises and
collecting the rents, any funds expended by the Lender for such purposes shall
become indebtedness of the Mortgagor to the Lender secured by this Mortgage as
if originally included in the Obligations.  Such amounts shall be payable upon
notice from the Lender to the Mortgagor requesting payment thereof and shall
bear interest from the date of disbursement at the Highest Lawful Rate, unless
payment of interest at such rate would be contrary to applicable law, in which
event such amounts shall bear interest at the highest rate which may be
collected

                                       14
<PAGE>

from the Mortgagor under applicable law. In the event the Lender elects to seek
the appointment of a receiver for the Premises following an Event of Default,
the Mortgagor hereby expressly consents to the appointment of a receiver. The
receiver shall be entitled to receive a reasonable fee for so managing the
Property.

          7.6  No Waiver by the Lender.  The failure of the Lender to exercise
               -----------------------
any right or remedy or option provided for herein or under applicable law shall
not be deemed to be a waiver of any of the covenants or obligations secured by
this Mortgage or otherwise.  No sale of all or any of the Premises, no
forbearance on the part of the Lender, no release or partial release of any of
the Premises, and no extension, whether oral or in writing, of the time for the
payment of the whole or any part of the Obligations or any other indulgence
given by the Lender to the Mortgagor, shall operate to release or in any manner
affect the lien of the Mortgage with respect to those portions of the Premises
not released pursuant to Section 8.7 or the original liability of the Mortgagor,
notice of any such extensions or indulgences being hereby waived by the
Mortgagor.  Any entering upon and taking and maintaining of control of the
Premises by the Lender, the receiver or any agent thereof, and any application
of rents as provided herein shall not cure or waive any default hereunder or
invalidate any other right or remedy of the Lender under applicable law or
provided herein.

          7.7  Mortgagor's Waiver of Certain Rights.  The Mortgagor hereby
               ------------------------------------
waives, to the fullest extent permitted by law, (i) the benefit of all laws now
existing or that hereafter may be enacted providing for any appraisement before
sale of any portion of the Premises, and (ii) the benefit of all laws that
hereafter may be enacted in any way extending the time for the enforcement or
the collection of the Obligations or creating or extending a period of
redemption from any sale made in collecting the Obligations.  The Lender shall
not be required to marshal the Premises, the Leases, rents, issues and profits
assigned by the Assignment, or any other Security in any particular order.  The
Mortgagor hereby covenants and agrees that it will not enforce or otherwise
exercise any rights of reimbursement, subrogation, contribution or other similar
rights against any co-obligor obligated on or with respect to any Obligations or
granting any security prior to the payment in full of the Obligations.

                            8.  GENERAL PROVISIONS.
                                ------------------

          8.1  Lender's Expenses.  Any and all costs and expenses reasonably
               -----------------
incurred by the Lender in connection with performing (but not making),
protecting or collecting the Obligations and the Loan, including, without
limitation, reasonable attorneys' fees, shall be paid by the Mortgagor on the
demand of the Lender and if not so paid on demand shall become part of the
Obligations and accrue interest at the default rate set forth in the Loan
Documents.  Without limiting the generality of the preceding sentence:  (a) if
the Lender is made a party defendant to any litigation concerning this Mortgage
or the Premises, then the Mortgagor shall indemnify, defend and hold the Lender
harmless from and against all claims, liabilities, judgments, costs and expenses
by reason of said litigation, including reasonable attorneys' fees and expenses
incurred by the Lender in any such litigation, whether or not any such
litigation is prosecuted to judgment; or (b) if the Mortgagor breaches any
provision of this Mortgage or any of the other Loan Documents, the Lender may
employ an attorney or attorneys to protect its rights hereunder or thereunder,
and in the event of such employment following any breach by the

                                       15
<PAGE>

Mortgagor, then the Mortgagor shall pay the reasonable attorneys' fees and
expenses incurred by the Lender, whether or not an action is actually commenced
against the Mortgagor by reason of such breach or whether or not any such
action, once commenced, is prosecuted to judgment.

          8.2  Construction, etc.  The interpretation of the provisions of this
               ------------------
Mortgage and any of the other Loan Documents shall not be construed against any
party hereto based upon the fact that such party may have drafted or caused to
be drafted such provision.  The Mortgagor hereby acknowledges that it has been
represented by independent counsel of its own selection and, notwithstanding
that counsel for the Lender has prepared the first draft of this Mortgage and
the other Loan Documents, the Mortgagor hereby agrees that the same shall not be
construed against the Lender in the event of any ambiguity, in that each party's
counsel participated in the negotiation and codification of this Mortgage and
the other Loan Documents.  Further, no prior draft or version of this Mortgage
or any other Loan Document may be used or relied upon to interpret or construe
any term or provision, or the absence of any term or provision, hereof or
thereof.  This instrument, together with all other Loan Documents, merges all
prior and contemporaneous agreements, understandings, warranties and
representations of the parties hereto.

          8.3  Notices.  All notices and other communications required or
               -------
permitted to be given hereunder shall be made in the manner and to the addresses
set forth in the Loan Agreement.

          8.4  Amendments.  This Mortgage may not be waived, changed or
               ----------
discharged orally, but only by an agreement in writing, signed by all parties,
and any attempted oral waiver, change or discharge of any provision of this
Mortgage shall have no force or effect.

          8.5  Waiver of Statute of Limitations.  The Mortgagor hereby waives
               --------------------------------
the right to assert any statute of limitations as a bar to the enforcement of
the lien of this Mortgage or any other provision herein, or to any action
brought to enforce the Loan Documents or any of the other Obligations secured by
this Mortgage.

          8.6  Miscellaneous.  Section captions are not a part hereof.  The
               -------------
invalidity of any provisions of this Mortgage, as determined by a court of
competent jurisdiction, shall in no way affect the validity of any other
provisions hereof.  This Mortgage shall be interpreted in accordance with and
governed by the laws of The State of Delaware.  This Mortgage shall be binding
upon and inure to the benefit of the respective permitted successors and assigns
of the parties hereto.  The term "Mortgagor", together with any pronoun
referring thereto, shall include the singular, plural, masculine, feminine and
neuter, as the context may require; and if more than one person constitutes any
of such parties, the obligations of such persons shall be joint and several.

          8.7  Defeasance.  Upon full payment and performance of all Obligations
               ----------
in accordance with the terms of the Loan Documents, Lender shall, at Mortgagor's
request and expense, release this Mortgage of record, whereupon this Mortgage
shall have no further force or effect, except as expressly provided herein.
Following any conveyance, sale, assignment, transfer or disposal of ownership or
control of all of Mortgagor's interest in the Premises to which Lender consents
in accordance with Section 3.2(b), Lender shall release this Mortgage of

                                       16
<PAGE>

record at Morgagor's cost. No release of this Mortgage or the lien hereof shall
be valid unless executed by Lender.

          8.8  Conflict.  In the event of any conflict between the terms,
               --------
provisions or conditions of this Mortgage and the terms, provisions or
conditions of the Loan Agreement, the terms, provisions or conditions of the
Loan Agreement shall govern.

     This Mortgage has been executed and delivered for fair and adequate
consideration, and does not constitute a fraudulent conveyance under applicable
law.

     If any provision hereof or the application thereof to any person or
circumstance should be invalid or unenforceable to any extent, the remainder
hereof, or the application of such provision to persons or circumstances other
than those as to which it is held invalid or unenforceable, shall not be
affected thereby, and each provision hereof shall be valid and enforced to the
fullest extent permitted by law.

     This Mortgage may not be amended orally and time is of the essence in
connection with each and every obligation of the Mortgagor hereunder.

          8.9  No Recourse.  No shareholder, director, officer, agent,
               -----------
affiliate, or employee of the Mortgagor shall have any personal liability under
this Mortgage and no judgment shall be sought, obtained or enforced against any
such person or entity, except with respect to Costs alleged to be based on the
willful misconduct or gross negligence of such party.
