payable in case of loss to Lender, and shall contain mortgage clauses and
lender's loss payable endorsements in form and substance acceptable to Lender.
Borrower shall deliver duplicate originals or certified copies of all such
policies to Lender, and Borrower shall promptly furnish to Lender all renewal
notices and all receipts of paid premiums. At least thirty (30) days prior to
the expiration date of the policies, Borrower shall deliver to Lender duplicate
originals or certified copies of renewal policies in form satisfactory to Lender

     (b)  All policies of insurance required by this Security Deed shall contain
clauses or endorsements to the effect that (i) no act or omission of either
Borrower or anyone acting for Borrower (including, without limitation, any
representations made by Borrower in the procurement of such insurance), which
might otherwise result in a forfeiture of such insurance or any part thereof, no
occupancy or use of the Property for purposes more hazardous than permitted by
the terms of the policy, and no foreclosure or any other change in title to the
Property or any part thereof, shall affect the validity or enforceability or
such insurance insofar as Lender is concerned, (ii) the insurer waives any right
of setoff, counterclaim, subrogation, or any deduction in respect of any
liability of Borrower and Lender, (iii) such insurance is primary and without
right of contribution from any other insurance which may be available, (iv) such

an aggregate limits of insurance per location endorsement in the case of
liability insurance.

     (d)  All policies of insurance required by this Security Deed shall be

give immediate written notice to the insurance carrier and Lender. Borrower
hereby irrevocably authorizes and empowers Lender, at Lender's option and in

<PAGE>

policies, to appear in and prosecute any action arising from such insurance
policies, to collect and receive insurance proceeds, and to deduct therefrom
Lender's expenses incurred in the collection of such proceeds. If Borrower is
not then in default under the Loan Documents, Lender will agree to the use of
insurance proceeds for reconstruction or repair of the Property, under Lender's
usual construction loan procedures. Otherwise, Lender is authorized to apply the
balance of such proceeds to the payment of the Secured Obligations whether or
not then due. If Lender shall require or if Borrower desires to proceed with
(and is not otherwise in default) the reconstruction or repair of the Property,
to hold the balance of such proceeds to be used to pay Impositions and the
Secured Obligations as they become due during the course of reconstruction or
repair of the Property and to reimburse Borrower, in accordance with such terms
and conditions as Lender may prescribe, for the costs of reconstruction or
repair of the Property, and upon completion of such reconstruction or repair to
apply any excess to the payment of the Secured Obligations. If under Paragraph
22 hereof the Property is sold or the Property is acquired by Lender, all right,
title and interest of Borrower in and to any insurance policies and unearned
premiums thereon and in and to the proceeds thereof resulting from loss or
damage to the Property prior to the sale or acquisition shall pass to Lender or
any other successor in interest to Borrower or purchaser or grantor of the
Property but receipt of any insurance proceeds and any disposition of the same
by Lender shall not constitute a waiver of any rights of Lender, statutory or
otherwise, and specifically shall not constitute a waiver of the right of
foreclosure by Lender in the event of Default or failure of performance by
Borrower of any of the Obligations.

     5.   Preservation and Maintenance. Borrower (a) shall not permit or commit
          ----------------------------

part of the Property in the event of any damage, injury or loss thereto, to the
equivalent of its condition prior to such damage, injury or loss, or such other
condition as Lender may approve in writing, provided that Lender shall release
net insurance proceeds, to the extent actually received by Lender, to Borrower
in accordance with the construction disbursement procedures specified in the
Loan Agreement (provided, however, the insufficiency of such proceeds shall not
relieve Borrower of its obligations to restore hereunder), (c) shall keep the
Property, including the Improvements and the Personal Property, in good order,
repair and tenantable condition and shall replace fixtures, equipment, machinery
and appliances on the Property when necessary to keep such items in good order,

ordinances, regulations and requirements of any governmental body applicable to

pending proceedings in respect thereto or with respect to the Property
(including, without limitation, changes in zoning). Neither Borrower nor any
tenant or other person shall remove, demolish or alter any Improvements now
existing or hereafter erected on the Property or any Personal Property in or on
the Property except when incident to the replacement of Personal Property with
items of like kind. Borrower further covenants and agrees that, without the
prior written consent of Lender herein, no part of the Property shall be
declared, or become the subject of, a condominium under the Maine Condominium
Act, as it may be amended or supplemented, or become the subject of any
covenants or restrictions, or any planned unit development, or any other type of
development that would control or restrict the uses to

                                       12
<PAGE>

which the Land and Improvements may be put or the scheme or arrangement or its
development or the design, location or character of its buildings or
improvements, or which would impose Obligations or assessments of any type upon
any owners or tenants of the Property, or upon any other parties who may use or
enjoy the Property.

     6.   Transfers. Borrower will not, directly or indirectly, voluntarily or
          ---------
involuntarily, without the prior written consent of Lender in each instance: (a)

in the zoning classification of the Property or subject the Property to
restrictive or negative covenants without Lender's written consent. Borrower
shall comply with, observe and perform all zoning and other laws affecting the
Property, all restrictive covenants affecting the Property, and all licenses and
permits affecting the Property.

     9.   Protection of Lender's Security. If Borrower fails to perform the
          -------------------------------
covenants and agreements contained in this Security Deed, or if any action or
proceeding is commenced which affects the Property or title thereto or the
interest of Lender therein, including, but not limited to, eminent domain,
insolvency, code enforcement or arrangements or proceedings involving a bankrupt
or decedent, then Lender at Lender's option may make such appearances, disburse
such sums and take such action as Lender deems necessary to protect Lender's
interest, including, but not limited to, disbursement of attorneys' fees,
payment, contest or compromise of any lien or security interest which is prior
to the lien or security interest of this Security Deed, and entry upon the
Property to make repairs. At its option, and without limitation, Lender may pay
any Impositions, or provide for the maintenance and preservation of the
Property. Any amounts

                                       17
<PAGE>

disbursed by Lender pursuant to this Paragraph 9, with interest thereon, shall
become a portion of the Secured Obligations. Unless Borrower and Lender agree to
other terms of payment, such amounts shall be payable upon notice from Lender to
Borrower requesting payment thereof and shall bear interest from the date of
disbursement at the Default Rate as that term is defined in the Note unless
collection from Borrower 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 from Borrower under applicable law. Borrower shall
have the right to prepay such amounts in whole or in part at any time. Nothing
contained in this Paragraph shall require Lender to incur any expense or do any
act.

     10.  Inspection. Lender may, at Borrower's expense, make or cause to be
          ----------
made reasonable entries upon and inspections of the Property during normal
business hours, or at any other time when necessary to protect or preserve the
Property.

     11.  Books and Records.
          -----------------

          (a)  Borrower shall keep and maintain at all times at Borrower's
address stated in this Security Deed, or such other place as Lender may approve
in writing, complete, proper and accurate records and books of account in which
full, true and correct entries shall be made in accordance with generally
accepted accounting principles reflecting the results of the operation of the
Property, and copies of all written contracts, leases and other instruments
which affect the Property. Such records, books of account, contracts, leases and
other instruments shall be subject to examination, inspection and copying by
Lender at any reasonable time by Lender and at Borrower's expense.

          (b)  Upon request of Lender in writing, Borrower shall promptly
provide Lender with all documents reasonably requested by Lender prepared in the
form and the manner called for in such request and as may reasonably relate to
the Property or the use, maintenance, operation or condition thereof, or the
financial condition of Borrower or any party obligated on the Note or under any
guaranty, including, without limitation, all leases or leasehold interests
granted to or by Borrower, rent rolls and tenant lists, rent and damage deposit
ledgers, operating statements, profit and loss statements and balance sheets,
personal financial statements of Borrower or income tax returns (including
quarterly returns), any or all of which documents shall be audited or certified
as true and accurate by a certified public accountant, if requested by Lender,
and shall cover such period or periods as may be specified by Lender

     12.  Condemnation. If all or substantially all of the Property shall be
          ------------
damaged or taken through condemnation (which term, when used in this Security
Deed, shall include any damage or taking by any governmental authority,
quasi-governmental authority, any party having the power of condemnation, or any
transfer by private sale in lieu thereof), either temporarily or permanently,
then the entire Secured Obligations shall, at the option of Lender, become
immediately due and payable. Borrower authorizes Lender, at Lender's option, as
attorney in fact for Borrower, to commence, appear in and prosecute, in Lender's
or Borrower's name, any action or proceeding relating to any condemnation or
other taking of the Property and to settle or compromise any claim in connection
with such condemnation or other taking. The proceeds of

                                       18
<PAGE>

any award or claim for damages, direct or consequential, in connection with any
condemnation, or other taking of the Property, or part thereof, or for
conveyances in lieu of condemnation, are hereby assigned and shall be paid to
Lender. Borrower authorizes Lender to apply such awards, proceeds or damages,
after the deduction of Lender's expenses incurred in the collection of such
amounts, and at Lender's option, to restoration or repair of the Property or to
payment of the Secured Obligations, whether or not then due, with the balance,
if any, to Borrower. Borrower agrees to execute such further assignment of any
awards, proceeds, damages or claims arising in connection with such condemnation
or injury that Lender may require. For the purposes of this Paragraph,
"substantially all of the Property" shall mean a taking of or damage to less
than the entire Property through condemnation, which in the good faith judgment
of Lender, renders the Property remaining after such taking or damage unsuitable
for restoration for the use intended to be made of the Property or substantially
the same value, condition, character or general utility as the then use which
existed on the Property before such condemnation.

     In the event that Borrower is required by the terms of its Sublease of the
Property to repair or restore the Property, following a partial taking, and if
Borrower is not then otherwise in default of the Secured Obligations, then
Lender agrees to release the proceeds of such partial taking, under its usual
construction loan disbursement procedures, with Borrower providing any necessary
equity injection required in the judgment of Lender to assure proper completion
of such repair or restoration, PROVIDED, HOWEVER, that prior to release of any
such proceeds, Borrower must pay down the Secured Obligations to the extent
required to maintain compliance with an 85% loan-to-value ratio, based upon
appraisals preceding the following completion of the work.

     13.  Borrower and Lien Not Released. From time to time, without affecting
          ------------------------------
the obligation of Borrower or Borrower's successors or assigns to pay or perform
the Secured Obligations and to observe the covenants of Borrower contained in
this Security Deed and the other Loan Documents, and without affecting the
guaranty of any person, corporation, partnership or other entity for payment or
performance of the Secured Obligations, and without affecting the lien or
priority of lien of this Security Deed on the Property, Lender may, at Lender's
option, without giving notice to or obtaining the consent of Borrower,
Borrower's successors or assigns or of any guarantor, and without liability on
Lender's part, grant extensions or postponements of the time for payment or
performance of the Secured Obligations or any part thereof, release anyone
liable on any of the Secured Obligations, accept a renewal note or notes
therefor, release from this Security Deed any part of the Property, take or
release other or additional security, re-convey any part of the Property,
consent to any map or plat or subdivision of the Property, consent to the
granting of any easement, join in any extension or subordination agreement and
agree in writing with Borrower to modify the rate of interest or terms and time
of payment or period of amortization of the Note or change the amount of the
monthly installments payable thereunder. Borrower shall pay Lender a reasonable
service charge, together with such title insurance premiums and attorneys' fees
as may be incurred, at Lender's option, for any such action if taken at
Borrower's request.

     14.  Forbearance Not Waiver. Any forbearance by Lender in exercising any
          ----------------------
right or remedy hereunder, or otherwise afforded by applicable law, shall not be
a waiver of or preclude

                                       19
<PAGE>

the exercise of any right or remedy hereunder. The procurement of insurance or
the payment of taxes or other liens or charges by Lender shall not be a waiver
of Lender's right to accelerate the maturity of the Secured Obligations or to
exercise any remedy in connection with the Secured Obligations. Lender's receipt
of any awards, proceeds or damages under Paragraphs 4 and 12 hereof shall not
operate to cure or waive Borrower's default in payment or performance of the
Secured Obligations.

     15.  Estoppel Certificates. Borrower shall within ten (10) days of a
          ---------------------
written request from Lender furnish Lender with a written statement, duly
acknowledged, setting forth the amount of the Secured Obligations and any right
of set-off, counterclaim or other defense which may exist or be claimed by
Borrower against the Secured Obligations and the obligations of Borrower under
this Security Deed.

     16.  Security Agreement. Insofar as any item of property included in the
          ------------------
Property which is or might be deemed to be "personal property" is concerned,
this Security Deed is hereby made and declared to be a security agreement,
granting a security interest in and to each and every item of such property
included in the Property (hereinafter collectively referred to as the
"Collateral"), in compliance with the provisions of the Uniform Commercial Code
as enacted in the Commonwealth of Massachusetts. A financing statement or
statements reciting this Security Deed to be a security agreement, covering all
of the Collateral, shall be executed by Borrower and Lender and appropriately
filed. The remedies for any violation of the covenants, terms and conditions of
the security agreement herein contained shall be (i) as prescribed herein, or
(ii) as prescribed by general law, or (iii) as prescribed by the specific
statutory consequences now or hereafter enacted and specified in said Uniform
Commercial Code, all at Lender's sole election. Borrower and Lender agree that
the filing of such financing statement(s) in the records normally having to do
with personal property shall never be construed as in any wise derogating from
or impairing this declaration and hereby stated intention of Borrower and Lender
that everything used in connection with the production of income from the
Property and/or adapted for use therein and/or which is described or reflected
in this Security Deed, is, and at all times and for all purposes and in all
proceedings both legal or equitable shall be, regarded as part of the real
estate irrespective of whether (i) any such item is physically attached to the
Land or the Improvements, (ii) serial numbers are used for the better
identification of certain items capable of being thus identified in a recital
contained herein, or (iii) any such item is referred to or reflected in any such
financing statement(s) so filed at any time. Similarly, the mention in any such
financing statement(s) of the rights in and to the proceeds of any hazard
insurance policy, or any award in eminent domain proceedings for a taking or for
loss of value, or Borrower's interest as lessor in any present or future lease
or rights to income growing out of the use and/or occupancy of the Property,
whether pursuant to lease or otherwise, shall never be construed as in any wise
altering any of the rights of Lender as determined by this instrument or
impugning the priority of Lender's lien granted hereby or by any other recorded
document, but such mention in such financing statement(s) is declared to be for
the protection of Lender in the event any court shall at any time hold, with
respect to any such matter, that notice of Lender's priority of interest, to be
effective against a particular class of persons, must be filed in the records of
the Uniform Commercial Code kept with (a) the Secretary of State of the
Commonwealth of Massachusetts, (b) the Bristol County Registry of Deeds, and (c)
the New Bedford City Clerk's Office. Borrower warrants that

                                       20
<PAGE>

(i) Borrower's (that is, "Debtor's") name, identity or organizational structure
and residence or principal place of business are as set forth in Exhibit C
                                                                 ---------
attached hereto and by this reference made a part hereof, (ii) Borrower (that
is, "Debtor") has been using or operating under said name, identity or
organizational structure without change for the time period set forth in Exhibit
                                                                         -------
C attached hereto and by this reference made a part hereof, and (iii) the
-
location of all collateral constituting fixtures is upon the Land. Borrower
covenants and agrees that Borrower will furnish Lender with notice of any change
in name, identity, organizational structure, residence or principal place of
business within thirty (30) days of the effective date of any such change and
Borrower will promptly execute any financing statements or other instruments
deemed necessary by Lender to prevent any filed financing statement from
becoming misleading or losing its perfected status. The information contained in
this Paragraph is provided in order that this Security Deed shall comply with
the requirements of the Uniform Commercial Code, as enacted in the Commonwealth
of Massachusetts, for instruments to be filed as financing statements. The names
of the "Debtor" and the "Secured Party", the identity or organizational
structure and residence or principal place of business of "Debtor", and the time
period for which "Debtor" has been using or operating under said name and
identity or organizational structure without change, are as set forth in
Schedule 1 of Exhibit C attached hereto and by this reference made a part
              ---------
hereof, the mailing address of the "Secured Party" from which information
concerning the security interest may be obtained, and the mailing address of
"Debtor", are as set forth in Schedule 2 of said Exhibit C attached hereto; and
                                                 ---------
a statement indicating the types, or describing the items, of collateral is set
forth in this Security Deed.

     17.  Assignment of Leases and Revenues.
          ---------------------------------

     (a)  As part of the consideration for the Secured Obligations, Borrower has
absolutely and unconditionally assigned and transferred to Lender all of
Borrower's right, title and interest in and to the Leases and the Revenues,
including those now due, past due or to become due by virtue of any Sublease for
the occupancy or use of all or any part of the Property. Borrower hereby
authorizes Lender or Lender's agents to collect the Revenues and hereby directs
such tenants, lessees and licensees of the Property to pay the Revenues to
Lender or Lender's agents; provided, however, that prior to written notice given
by Lender to Borrower of any Event of Default by Borrower, Borrower shall
collect and receive the Revenues as trustee for the benefit of Lender, to apply
the Revenues so collected to the Secured Obligations, to the extent then due,
with the balance, so long as no Event of Default has occurred, to the account of
Borrower. Borrower agrees that each and every tenant, lessee and licensee of the
Property shall pay, and hereby irrevocably authorizes and directs each and every
tenant, lessee and licensee of the Property to pay, the Revenues to Lender or
Lender's agents on Lender's written demand therefor without any obligation on
the part of said tenant, lessee or licensee to inquire as to the existence of an
Event of Default and notwithstanding any notice or claim of Borrower to the
contrary, and Borrower agrees that Borrower shall have no right or claim against
said tenant, lessee or licensee for or by reason of any Revenues paid to Lender
following receipt of such written demand.

     (b)  Borrower hereby covenants that Borrower has not executed any prior
assignment of the Leases or the Revenues, that Borrower has not performed, and
will not perform, any acts or has not executed, and will not execute, any
instruments which would prevent Lender from

                                       21
<PAGE>

exercising the rights of holder under this Security Deed, and that at the time
of execution of this Security Deed, there has been no anticipation or prepayment
of any of the Revenues for more than one (1) month prior to the due dates of
such Revenues. Borrower further covenants that Borrower will not hereafter
collect or accept payment of any Revenues more than one (1) month prior to the
due dates of such Revenues.

     (c)  Borrower agrees that neither the foregoing assignment of Leases and
Revenues nor the exercise of any of Lender's rights and remedies under Paragraph
22 hereof shall be deemed to make Lender a mortgagee-in-possession or otherwise
responsible or liable in any manner with respect to the Leases, the Property or
the use, occupancy, enjoyment or operation of all or any portion thereof, unless
and until Lender, in person or by agent, assumes actual possession thereof. Nor
shall the appointment of any receiver for the Property by any court at the
request of Lender or by agreement with Borrower, or the entering into possession
of any part of the Property by such receiver, be deemed to make Lender a
mortgagee-in-possession or otherwise responsible or liable in any manner with
respect to the Leases, the Property or the use, occupancy, enjoyment or
operation of all or any portion thereof.

     (d)  If Lender or a court-appointed receiver enters upon, takes possession
of and maintains control of the Property pursuant to this Security Deed, all
Revenues thereafter collected shall be applied first to the costs of taking
control of and managing the Property and collecting the Revenues, including, but
not limited to, reasonable attorneys' fees actually incurred, receiver's fees,
premiums on receiver's bonds, costs of repairs to the Property, premiums on
insurance policies, Impositions and other charges on the Property, and the costs
of discharging any obligation or liability of Borrower as landlord, lessor or
licensor of the Property and then to the Secured Obligations. Lender or the
receiver shall have access to the books and records used in the operation and
maintenance of the Property and shall be liable to account only for those
Revenues actually received. Lender shall not be liable to Borrower, anyone
claiming under or through Borrower or anyone having an interest in the Property
by reason of anything done or left undone by Lender. If the Revenues are not
sufficient to meet the costs of taking control of and managing the Property and
collecting the Revenues, any monies expended by Lender for such purposes shall
become a portion of the Secured Obligations. Unless Lender and Borrower agree in
writing to other terms of payment, such amounts shall be payable upon notice
from Lender to Borrower requesting payment thereof and shall bear interest from
the date of disbursement at the Default Rate as that term is defined in the Note
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 from Borrower under applicable law. The entering upon and taking
possession of and maintaining of control of the Property by Lender or the
receiver and the application of Revenues as provided herein shall not cure or
waive any Event of Default or invalidate any other right or remedy of Lender
hereunder.

     18.  Leases of the Property. Borrower will not enter into any sublease of
          ----------------------
all or any portion of the Property unless such sublease shall be upon a form of
lease previously approved by Lender or as approved under the Loan Agreement
provided, however, that after any Event of Default shall have occurred hereunder
and until such time as such Event of Default has either been cured with a
written consent of Lender or the Event of Default has been waived in writing

                                       22
<PAGE>

by Lender, Borrower will not enter into any sublease of all or any portion of
the Property, Borrower will not enter into any sublease of all or any portion of
the Property or amend, supplement or otherwise modify, or terminate or cancel,
or accept the surrender of, or consent to the assignment or subletting of, or
grant any concessions to or waive the performance of any obligations of any
tenant, lessee or licensee under, any now existing or future sublease of the
Property, without the prior written consent of Lender. Borrower, at Lender's
request, shall furnish Lender with executed copies of all Leases hereafter made
of all or any part of the Property, and all Leases now or hereafter entered into
will be in form and substance subject to the approval of Lender. Upon Lender's
request, Borrower shall make a separate and distinct assignment to Lender, as
additional security, of all Leases hereafter made of all or any part of the
Property.

     19.  Remedies Cumulative. All remedies provided in this Security Deed are
          -------------------
distinct and cumulative to any other right or remedy under this Security Deed or
under the other Loan Documents or afforded by law or equity, and may be
exercised concurrently, independently or successively.

     20.  Taxation of Security Deeds. In the event of the enactment of any law
          --------------------------
deducting from the value of the Property any mortgage lien thereon, or imposing
upon Lender the payment of all or part of the taxes, charges or assessments
previously paid by Borrower pursuant to this Security Deed, or changing the law
relating to the taxation of mortgages or debts secured by mortgages or Lender's
interest in the Property so as to impose new incidents of tax on Lender, then
Borrower shall pay such taxes or assessments or shall reimburse Lender therefor;
provided, however, that if in the opinion of counsel to Lender, such payment
cannot lawfully be made by Borrower, and such change in the law cannot be
remedied and lawful payment made by Borrower to the reasonable satisfaction of
Lender within thirty (30) days following notice to Borrower by Lender of the
occurrence of such change, then Lender may, at Lender's option, declare the
Secured Obligations to be immediately due and payable and invoke any remedies
permitted by Paragraph 22 of this Security Deed.

     21.  Events of Default and Acceleration. The term "Event of Default",
          ----------------------------------
wherever used in this Security Deed, shall mean any one or more of the following
conditions or events:

     (a)  Failure by Borrower to pay as and when due and payable any interest on
or principal of or other sum payable under the Note; or

     (b)  Failure by Borrower to pay as and when due and payable any sums to be
paid by Borrower under this Security Deed (including, but not limited to, any
payment of Funds) or the Reimbursement Agreement; or

     (c)  Failure by Borrower to duly observe or perform any term, covenant,
condition or agreement contained in this Security Deed (other than the
obligations to make payments referred to in subparagraph (b) above) contained in
Paragraphs 3 or 4 of this Security Deed and continuance of such failure for a
period of thirty (30) days after written notice thereof from Lender; or

                                       23
<PAGE>

     (d)  Failure by Borrower to duly observe or perform any other term,
covenant, condition or agreement contained in Paragraphs 6 or 7 of this Security
Deed; and with respect to Borrower's obligations to comply with all applicable
Environmental Laws, including either or both the clean-up and removal of
Hazardous Materials present on the Property, Borrower shall have at least twenty
(20) days to achieve such full compliance after written notice from Lender
requiring such compliance, if Borrower shall commence and diligently pursue to
full compliance in accordance with the terms of Paragraph 7, plus such
additional time as Lender, in its sole judgment, shall allow Borrower for such
compliance; provided, however, Lender may in its sole judgment, declare an Event
of Default to exist by written notice thereof to Borrower at any time after the
expiration of such twenty (20) day period if such full compliance with all
applicable Environmental Laws shall not have been so achieved at the time of
such notice; or hand continuance of such failure for a period of five (5) days
after notice thereof from Lender; or

     (e)  Failure by Borrower to duly observe or perform any other term,
covenant, condition or agreement contained in this Security Deed or the Loan
Agreement and continuance of such failure for a period of twenty (20) days after
written notice thereof from Lender; or

     (f)  Any representation or warranty of Borrower contained in this Security
Deed or the Reimbursement Agreement or the Note Pledge Agreement or the Loan
Agreement shall prove to have been false or incorrect in any material respect
upon the date when made; or

     (g)  Without the prior written consent of Lender, any change in the
majority of the voting stock of Borrower, any merger, reorganization,
dissolution or termination of existence of Borrower as a corporation; or

     (h)  The filing by Borrower or any guarantor of the Obligations of a
voluntary petition in bankruptcy under Title 11 of the United States Code, or
the issuing of an order for relief against Borrower or any guarantor in any
involuntary petition in bankruptcy under Title 11 of the United States Code, or
the filing by Borrower or any guarantor of any petition or answer seeking or
acquiescing in any reorganization, arrangement, composition, readjustment,
liquidation, dissolution or similar relief for itself under any present or
future federal, state or other law or regulation relating to bankruptcy,
insolvency or, other relief for debtors, or Borrower's or any guarantor's
seeking or consenting to or acquiescing in the appointment of any custodian,
trustee, receiver, conservator or liquidator of Borrower or such guarantor,
respectively, or of all or any substantial part of its respective property, or
the making by Borrower or any guarantor of any assignment for the benefit of
creditors, or Borrower's or any guarantor's failure generally to pay its debts,
as such debts become due, or Borrower's or any guarantor's giving of notice to
any governmental authority or body of insolvency or pending insolvency or
suspension of operations; or

     (i)  The entry by a court of competent jurisdiction of any order, judgment
or decree approving a petition filed against Borrower or any guarantor of the
Obligations seeking any reorganization, arrangement, composition, readjustment,

state or other law or regulation relating to bankruptcy,

                                       24
<PAGE>

insolvency or other relief for debtors, or appointing any custodian, trustee,
receiver, conservator or liquidator of all or any substantial part of Borrower's
or any guarantor's property; or

     (j)  The occurrence of any "Event of Default" as defined in the Sublease,
the Reimbursement Agreement or any of the other Loan Documents executed by
Borrower and continuation of such default beyond any grace period set forth
therein for the curing thereof, or

     (k)  Such a change in the condition or affairs (financial or otherwise) of
the Borrower or of any obligor, endorser, guarantor or surety under or for any
of the Secured Obligations, or decline in the value of the Property as, in the
opinion of the Lender, materially impairs the Lender's security or increases its
risk or if the Lender in good faith deems itself insecure; or

     (l)  Default after the expiration of any applicable cure period in the
prompt payment, performance or observance of any material term, provision,
condition, covenant, warranty or representation set forth in any mortgages,
liens, lease or encumbrances affecting the Property, whether or not such
mortgage, lien, lease or encumbrance is senior or junior to this Mortgage, and
whether or not such mortgage, lien, lease or encumbrance has been consented to
by Lender, provided, however, that nothing herein shall be deemed to be a
consent by Lender, implied or otherwise, to the granting of any mortgage, lien
or encumbrance on the Premises.

     If an Event of Default shall have occurred, Lender may, at Lender's option,
by notice to Borrower declare the entire Secured Obligations to be immediately
due and payable, whereupon the same shall become immediately due and payable,
and without presentment, protest, demand or other notice of any kind, all of
which are hereby expressly waived by Borrower and Lender may exercise any and
all of its remedies; provided that if any Event of Default specified in clauses
                     --------
(g), (h), (i), (k) or (l) of this Paragraph shall occur, the Secured Obligations
automatically shall become and be immediately due and payable and Lender may
exercise any and all of its remedies, without any declaration or other act on
the part of Lender, unless a notice of grace period shall be given therein for
any specific type of Event of Default. No omission on the part of Lender to
exercise such option when entitled to do so shall be construed as a waiver of
such right.


     22.  Rights and Remedies.
          -------------------

     (a)  Power of Sale and other Remedies. Upon the occurrence of any Event of
          --------------------------------
Default, and whether or not Lender shall have accelerated the maturity of the
Secured Obligations pursuant to Paragraph 21 hereof, Lender, at its option, may
take the following actions or any one or more of them from time to time:

          (i)  Declare any one or more of the Secured Obligations immediately
due and payable;

          (ii) Cease advancing money or extending credit to or for the benefit
of the Borrower under any agreement, whether or not secured hereby;

                                       25
<PAGE>

          (iii)   Foreclose this Security Deed under any legal method of
foreclosure in existence at the time or now existing, or under any other
applicable law, including, without limitation, the Statutory Power of Sale,
which is incorporated herein by reference, and if the Property consists of
multiple parcels or units, to foreclose against the entire Property or such
portions thereof in such order and at such times as Lender may determine all in
its discretion, and the deferral or delay in foreclosure against any portion of
the Property shall not impair the right of Lender to subsequently foreclose;

          (iv)    either with or without entering upon or taking possession of
the Property, demand, collect and receive any or all Revenues;

          (v)     take possession of all or any part of the Collateral, and for
such purpose Lender may, so far as Borrower can give authority, enter upon any
premises on which the Collateral or any part thereof may be situated and remove
the same;

          (vi)    either with or without taking possession of the Collateral,
sell, lease or otherwise dispose of the Collateral in its then condition or
following such preparation as Lender deems advisable;

          (vii)   either with or without entering upon or taking possession of
the Property, and without assuming any obligations of Borrower thereunder,
exercise the rights of Borrower under, use or benefit from, any of the Plans,
Leases, the Sublease or Intangible Property;

          (viii)  in person, by agent or by court appointed receiver, enter
upon, take possession of, and maintain full control of the Property in order to
perform all acts necessary or appropriate to complete the Improvements and to
maintain and operate the Property, including, but not limited to, the execution,
cancellation or modification of Leases, the making of repairs to the Property
and the execution or termination of contracts providing for the improvement,
management or maintenance of the Property, all on such terms as Lender, in its
sole discretion, deems proper or appropriate;

          (ix)    proceed by a suit or suits in law or in equity or by other
appropriate proceeding against Borrower or any other party liable to enforce
payment of the Secured Obligations or the performance of any term, covenant,
condition or agreement of this Security Deed, the Loan Agreement, the
Reimbursement Agreement, or any of the other Loan Documents, or any other right,
and to pursue any other remedy available to it, all as Lender shall determine
most effectual for such purposes;

          (x)     institute and maintain such suits and proceedings as Lender
may deem expedient to prevent any impairment of the Property by any acts which
may be unlawful or in violation of this Security Deed, to preserve or protects
its interest in the Property and the Revenues, and to restrain the enforcement
of or compliance with any legislation or other governmental enactment, rule or
order that would impair the security hereunder or be prejudicial to the interest
of Lender. Borrower recognizes that in the event Borrower defaults, no remedy of
law will provide adequate relief to Lender, and therefore Borrower agrees that
Lender shall be

                                       26
<PAGE>

entitled to temporary and permanent injunctive relief to cure any such Default
without the necessity of proving actual damages;

          (xi)   apply all or any portion of the Property, or the proceeds
thereof, towards (but not necessarily in complete satisfaction of) the Secured
Obligations without being deemed to have waived any Event of Default;

          (xii)   foreclose any and all rights of Borrower in and to the
Property, whether by sale, entry or in any other manner provided for hereunder
or under the laws of the Commonwealth of Massachusetts whether now existing or
as hereafter arising;

          (xiii)  in the case of any receivership, insolvency, bankruptcy,
reorganization, arrangement, adjustment, composition or other proceedings
affecting Borrower or the creditors or property of Borrower, Lender, to the
extent permitted by law, shall be entitled to file such proofs of claim and
other documents as may be necessary or advisable in order to have the claims of
Lender allowed in such proceedings for the entire amount of the Secured
Obligations at the date of the institution of such proceedings and for any
additional portion of the Secured Obligations accruing after such date;

          (xiv)   exercise any other right or remedy of a mortgagee or secured
party under the laws of the Commonwealth of Massachusetts; and

          (xv)    Set-off against any and all deposits, accounts, certificate of
deposit balances, claims, or other sums at any time credited by or due from
Lender to Borrower and against all other property of Borrower in the possession
of Lender or under its control.

     (b)  Receiver. If an Event of Default shall have occurred, Lender, upon
          --------
application to a court of competent jurisdiction, shall be entitled as a matter
of strict right, without notice and without regard to the occupancy or value of
any security for the Secured Obligations or the solvency of any party bound for
its payment, to the appointment of a receiver to take possession of and to
operate the Property and to collect and apply the Revenues. The receiver shall
have all of the rights and powers permitted under the laws of the Commonwealth
of Massachusetts or otherwise existing. Borrower will pay to Lender upon demand,
all expenses, including receiver's fees, attorneys' fees, costs and agent's
compensation, incurred pursuant to such appointment and all such expenses shall
be a portion of the Secured Obligations.

     (c)  Sale or Other Disposition of Property. Any sale or other disposition
          -------------------------------------
of the Collateral may be at public or private sale, to the extent such private
sale is authorized under the provisions of the Uniform Commercial Code as
enacted in the Commonwealth of Massachusetts, upon such terms and in such manner
as Lender deems advisable. Lender may conduct any such sale or other disposition
of the Property upon the Land, in which event Lender shall not be liable for any
rent or charge for such use of the Land. Lender may purchase the Property, or
any portion of it, at any sale held under this Paragraph. With respect to any
Collateral to be sold pursuant to the Uniform Commercial Code, Lender shall give
Borrower at least seven (7) days written notice of the date, time, and place of
any proposed public sale, or such additional notice

                                       27
<PAGE>

as may be required under the laws of the Commonwealth of Massachusetts, and of
the date after which any private sale or other disposition may be made. Lender
may sell any of the Collateral as part of the real property comprising the
Property, or any portion or unit thereof, at the foreclosure sale or sales
conducted pursuant hereto. If the provisions of the Uniform Commercial Code are
applicable to any part of the Collateral which is to be sold in combination with
or as part of the real property comprising the Property, or any part thereof, at
one or more foreclosure sales, any notice required under such provisions shall
be fully satisfied by the notice given in execution of any method of
foreclosure, including, without limitation, the STATUTORY POWER OF SALE, with
respect to the real property or any part thereof. Borrower waives any right to
require the marshalling of any of its assets in connection with any disposition
conducted pursuant hereto. In the event all or part of the Property is included
at any foreclosure sale conducted pursuant hereto, a single total price for the
Property, or such part thereof as is sold, may be accepted by Lender with no
obligation to distinguish between the application of such proceeds amongst the
property comprising the Property. The obligations of Borrower to pay such
amounts shall be included in the Secured Obligations of Borrower to Lender and
shall accrue interest at the default rate of interest set forth in the Note.
Borrower agrees that all rights and remedies of Lender as to the Personal
Property and as to the Property, and all rights and interests appurtenant
thereto, shall be cumulative and may be exercised together or separately without
waiver by Lender of any other of its rights or remedies. Borrower further agrees
that any sale or other disposition by Lender of any of the Personal Property and
any rights and interests therein or appurtenant thereto, or any part thereof,
may be conducted either separately from or together with any foreclosure, sale
or other disposition of the Property, or any rights or interests therein or
appurtenant thereto, or any part thereof, all as the Lender may in its sole
discretion elect.

     (d)  Collection of Revenues. In connection with the exercise by Lender of
          ----------------------
the rights and remedies provided for in subparagraph (a)(ii) of this Paragraph:

          (i)    Lender may notify any tenant, lessee or licensee of the
Property, either in the name of Lender or Borrower, to make payment of Revenues
directly to Lender or Lender's agents, may advise any person of Lender's
interest in and to the Revenues, and may collect directly from such tenants,
lessees and licensees all amounts due on account of the Revenues;

          (ii)   At Lender's request, Borrower will provide written notification
to any or all tenants, lessees and licensees of the Property concerning Lender's
interest in the Revenues and will request that such tenants, lessees and
licensees forward payment thereof directly to Lender;

          (iii)  Borrower shall hold any proceeds and collections of any of the
Revenues in trust for Lender and shall not commingle such proceeds or
collections with any other funds of Borrower; and

          (iv)   Borrower shall deliver all such proceeds to Lender immediately
upon the receipt thereof by Borrower in the identical form received, but duly
endorsed or assigned on behalf of Borrower to Lender.

                                       28
<PAGE>

     The acceptance of payments and funds, and the application of such payments
and funds after the commencement of any foreclosure proceedings shall not waive
or impair such foreclosure or the defaults in the Secured Obligations.

     (e)  Use and Occupation of Property. In connection with the exercise of
          ------------------------------
Lender's rights under Subparagraph (a)(vi) of this Paragraph, Lender may enter
upon, occupy, and use all or any part of the Property and may exclude Borrower
from the Land and the Improvements or portion thereof as may have been so
entered upon, occupied, or used. Lender shall not be required to remove any
Personal Property from the Land and the Improvements upon Lender's taking
possession thereof, and may render any Personal Property unusable to Borrower.
In the event Lender manages the Land and the Improvements, Borrower shall pay
to Lender on demand a reasonable fee for the management thereof in addition to
the Secured Obligations. Further, Lender may make such alterations, renovations,
repairs, and replacements to the Improvements, as Lender, in its sole
discretion, deems proper or appropriate. The obligation of Borrower to pay such
amounts and all expenses incurred by Lender in the exercise of its rights
hereunder shall be included in the Secured Obligations and shall accrue interest
at the default rate of interest stated in the Note.

     (f)  Partial Sales. Borrower agrees that in case Lender, in the exercise of
          -------------
the power of sale contained herein or in the exercise of any other rights
hereunder given, elects to sell in parts or parcels, said sales may be held from
time to time and that the power shall not be exhausted until all of the Property
not previously sold shall have been sold, notwithstanding that the proceeds of
such sales exceed, or may exceed, the Secured Obligations.

     (g)  Assembly of Collateral. Upon the occurrence of any Event of Default,
          ----------------------
Lender may require Borrower to assemble the Collateral and make it available to
Lender, at Borrower's sole risk and expense, at a place or places to be
designated by Lender which are reasonably convenient to both Lender and
Borrower.

     (h)  Actions by Lender. Upon the occurrence of any Event of Default that
continues beyond any applicable grace or cure period, Borrower hereby
irrevocably constitutes and appoints Lender or any receiver appointed in
accordance with this Security Deed to be Borrower's true and lawful attorney in
fact to take any action with respect to the Property to preserve, protect, or
realize upon Lender's interest therein, each at the sole risk, cost and expense
of Borrower, but for the sole benefit of Lender. The rights and powers granted
by the within appointment include, but are not limited to, the right and power
to: (i) prosecute, defend, compromise, settle, or release any action relating to
the Property; (ii) endorse the name of Borrower upon any and all checks or other
items constituting Revenues; (iii) sign and endorse the name of Borrower on, and
to receive as secured party, any of the Collateral; (iv) sign and file or record
on behalf of Borrower any financing or other statement in order to perfect or
protect Lender's security interest; (v) enter into leases or subleases relative
to all or a portion of the Land or the Improvements; (vi) enter into any
contracts or agreements relative to, and to take all action deemed necessary in
connection with, any Improvements on the Land (vii) manage, operate, maintain,
or repair the Land and the Improvements; and (viii) exercise the rights of
Borrower under any Plans, Leases, or Intangible Personal Property. Such receiver
or Lender shall not be

                                       29
<PAGE>

obligated to perform any of such acts or to exercise any of such powers, but if
it so elects so to perform or exercise, it shall not be accountable for more
than it actually receives as a result of such exercise of power, and shall not
be responsible to Borrower except for willful misconduct or gross negligence.
All powers conferred by this Security Deed, being coupled with an interest,
shall be irrevocable until terminated by a written instrument executed by a duly
authorized officer of Lender or until payment of this Security Deed as shall
entitle the Borrower to a discharge of record of the lien hereof, whichever
shall first occur.

     23.  Sublease Covenants. Borrower, in its capacity as Sublessee under the
          ------------------
Sublease, covenants and agrees with Lender as follows regarding the Sublease:

     A.   (a)  Borrower holds a valid leasehold interest in the Property
described in the Sublease and that it may lawfully mortgage and assign the same
to Lender under this Security Deed.

          (b)  The description of the Sublease set forth in the Recitals hereof
contains a correct and complete description of the Sublease.

          (c)  Borrower has furnished to Lender a true and correct copy of the
Sublease.

          (d)  The Sublease has not been modified or assigned by Borrower or, to
the best knowledge of Borrower, assigned by the Authority as Sublessor
thereunder.

          (e)  The Sublease is in full force and effect, and to the best
knowledge of Borrower, there is no default under the Sublease and there exists
no condition which, with the giving of notice or passage of time or both, would
cause a default under the Sublease.

          (f)  The execution, delivery and performance of this Security Deed by
Borrower do not require any consent (other than those consents that have been
obtained and are in full force and effect) under, and will not contravene any
provision of or cause a default under, the Sublease.

          (g)  Borrower shall duly and punctually pay, perform and observe all
of its obligations under the Sublease.

          (h)  Borrower shall do all things necessary or appropriate to enforce,
preserve and keep unimpaired the rights of Borrower in its capacity as Sublessee
under the Sublease.

          (i)  Borrower shall not terminate, cancel, sever or surrender, or
suffer the termination, cancellation, severance or surrender, of the Sublease or
the subleasehold interest in the Sublease, and any attempt on the part of
Borrower to exercise any such right without the prior written consent of Lender
shall be void.

          (j)  Borrower shall not modify or amend the Sublease or otherwise
waive, excuse, release or discharge Sublessor without the prior written consent
of Lender.

                                       30
<PAGE>

          (k)  Borrower irrevocably assigns to Lender the right to exercise (i)
any right to extend the term of the Sublease and (ii) any option to purchase or
otherwise acquire the interest of either the Authority or the City, if any,
under the Sublease.

          (l)  Borrower shall notify Lender (i) promptly after receipt
contemporaneously when given, as the case may be, of the receipt or giving by
Borrower of any notice of default under the Sublease or of any notice of the
possible or actual termination thereof, or of the possible or actual termination
of any material right of Borrower thereunder or any material obligation of any
other party thereunder, accompanied by a copy of such notice, (ii) promptly
after learning about any condition, or the existence of any condition which,
with or without the giving of notice or the passage of time or both, would
constitute a default under the Sublease or any termination thereof, (iii)
promptly after receiving or learning of the existence of any assignment, or the
existence of any assignment of the interest of the Authority under the Sublease,
accompanied by a copy of such assignment received by Borrower, and (iv) promptly
after receipt or contemporaneously when given, as the case may be, of the
receipt or giving of any notice relating to any option to purchase or right of
first refusal under the Sublease, accompanied by a copy of such notice.

     B.   The provisions of this Paragraph 22 shall also apply to any right of
Borrower, in its capacity as Sublessee under the Sublease, to retain its rights
under the Sublease under (S)365 of the Bankruptcy Code in the event the Sublease
is rejected by any other party thereunder or its Trustee pursuant to said
(S)365.

     C.   In the event Borrower in its capacity as sublessee under the sublease
acquires the fee simple title or any other greater estate or interest in the
Land, such acquisitions will not merge with the leasehold estate created by the
Sublease, but such other title, estate or interest will remain discrete, shall
immediately and automatically become subject to the lien of this Security Deed,
and such title, estate or interest shall be part of the Property and included
within the term and definition of "Land". Borrower in its capacity as sublessor
under the Sublease shall execute, acknowledge and deliver any instruments
requested by Lender to confirm the coverage of the lien hereof upon such other
greater estate or interest. Borrower in its capacity as sublesee under the
Sublease shall pay any and all conveyance or mortgage taxes, and filing or
similar fees in connection with the execution, delivery, filing or recording of
any such instrument.

     D.   Borrower in its capacity as sublessee under the Sublease hereby
unconditionally assigns, transfers and sets over to Lender all of Borrower's
claims and rights to the payment of damages that may hereafter arise from any
rejection of Borrower's subleasehold interest in the Sublease by the Authority
or the City or by any trustee of any such party pursuant to the Bankruptcy Code.
Lender shall have the right, and is hereby granted the right, to proceed in its
own name or in the name of Borrower in its capacity as sublessee under the
Sublease in respect of any claim, suit, action or proceeding relating to the
rejection of the Sublease including, without limitation, the right to file and
prosecute, to the exclusion of Borrower in its capacity as sublessee under the
Sublease, any proofs of claim, complaints, motions, applications, notices and
other documents, in any case in respect of the Authority or the City under the
Bankruptcy Code.

                                       31
<PAGE>

This assignment constitutes a present, irrevocable and unconditional assignment
of the foregoing claims, rights and remedies, and shall continue in effect until
the termination of this Security Deed in the manner and at the time provided in
Paragraph 29. Any amounts received by Lender as damages arising out of any such
rejection of the Sublease as a foresaid shall be applied and paid as set forth
herein.

     E.   Borrower in its capacity as Sublessee under the sublease shall not,
without Lender's prior written consent, elect to treat the Sublease or
Borrower's subleasehold interest under the Sublease as terminated under Section
365(h)(1) of the Bankruptcy Code after the rejection of the Sublease or the
subleasehold interest under the sublease by the Authority or the City, as
applicable, or by any trustee of such party. Any election made without Lender's
prior consent shall be void. Borrower hereby expressly assigns, releases,
relinquishes and surrenders unto Lender all of its right, power and authority to
cancel, terminate, surrender, sever, amend, modify or alter in any respect the
terms and provisions of the Sublease or the subleasehold interest under the
Sublease.

     F.   If pursuant to Section 365(h)(1) of the Bankruptcy Code, Borrower in
its capacity as sublessee under the Sublease seeks to offset against the rent or
other charges reserved in the Sublease, the amount of any damages caused by the
non-performance of the Authority of any of the Authority's obligations under
this Sublease after the rejection by the Authority of the Sublease under the
Bankruptcy Code, Borrower in its capacity as sublessee under the Sublease shall,
prior to effecting such offset, notify Lender of its intention to do so, setting
forth the amounts proposed to be so offset and the basis therefor. Lender shall
have the right, within ten (10) days after receipt of such notice from Borrower,
to reasonably object to all or any part of such offset and, in the event of such
reasonable objection, Borrower shall not effect any offset of the amount so
objected to by Lender for a period of sixty (60) days after Lender has delivered
its objection notice to Borrower, during which time Lender shall have the right
to bring its objections to the attention of any court supervising the bankruptcy
of the City or the Authority under the Sublease, and both Lender and Borrower in
its capacity as sublessee under the Sublease agreed to abide by the decision of
any such court. If (Y) Lender has failed to object as aforesaid within the ten
(10) days, after notice from Borrower, or (Z) the court fails to render its
decision within the above mentioned sixty (60) days, Borrower in its capacity as
sublessee under the Sublease may proceed to effect such offset in the amounts
set forth in Borrower's notice. Neither Lender's failure to object as aforesaid
nor any objection or other communication between Lender and Borrower in its
capacity as sublessee under the Sublease relating to such offset shall
constitute an approval of any such offset by Lender. Borrower in its capacity as
sublessee under the Sublease shall indemnify and hold Lender harmless of, from
and against any and all claims, demands, actions, suits, proceedings, damages,
losses, costs and expenses of every nature whatsoever (including, without
limitation, reasonable attorneys fees and disbursements) arising from or
relating to any offset by Borrower in its capacity as sublessee under the
Sublease.

     G.   If any action, proceeding, application, motion or notice shall be
commenced or filed in respect of the Authority or the City or in respect of all
or any part of the Property (including, without limitation, any proceeding
relating to the rejection of the Sublease or the subleasehold interest under the
Sublease) in connection with any case under the Bankruptcy Code

                                       32
<PAGE>

(other than a case under the Bankruptcy Code commenced with respect to Borrower
in any capacity), Lender shall have, and is hereby granted the right, but not
the obligation, to the exclusion of Borrower in its capacity as sublessee under
the Sublease, exercisable upon notice to Borrower in its capacity as sublessee
under the Sublease, to conduct and control any litigation with counsel of
Lender's choice. Lender may proceed in its own name or in the name of Borrower
in its capacity as sublessee under the Sublease in connection with any such
litigation, and Borrower in its capacity as sublessee under the Sublease agrees
to execute any and all powers, authorizations, consents and other documents
required by Lender in connection therewith. Borrower in its capacity as
sublessee under the Sublease shall pay to Lender or any person or entity that
Lender may designate all costs and expenses (including, without limitation,
reasonable attorneys fees and disbursements) and liabilities paid or incurred by
Lender in connection with the prosecution or conduct of any such proceeding
within five (5) days after notice from Lender setting forth such costs, expenses
and liabilities and reasonable detail. Any such costs, expenses or liabilities
not paid by Borrower in its capacity as sublessee under the Sublease as
aforesaid, shall be part of the Secured Obligations and shall be secured by this
Security Deed. Borrower in its capacity as sublessee under the Sublease shall
not commence any action, suit, proceeding or case, or file any application or
make any motion in any such case under the Bankruptcy Code (other than a case
under the Bankruptcy Code commenced with respect to Borrower in any capacity) in
respect of the Sublease without the prior written consent Lender, which consent
shall not be unreasonably withheld.

     H.   Borrower in its capacity as sublessee under the Sublease shall
promptly, after obtaining knowledge thereof, notify Lender orally of any filing
by or against the Authority under the Sublease of a petition under the
Bankruptcy Code. Borrower in its capacity as sublessee under the Sublease shall
thereafter forthwith give written notice of such filing to Lender setting forth
any information available to Borrower in its capacity as sublessee under the
Sublease as to the date of such filing, the court in which such petition was
filed and the relief sought therein. Borrower in its capacity as sublessee under
the Sublease shall promptly deliver to Lender following receipt of any and all
notices, summonses, pleadings, applications and other documents received by
Borrower in such capacity in connection with any such petition and any
proceedings relating thereto.

     I.   Borrower in its capacity as sublessee under the Sublease shall
promptly notify Lender orally of any filing by or against Borrower in its
capacity as sublessee under the Sublease of a petition under the Bankruptcy
Code. Borrower in its capacity as sublessee under the Sublease shall thereafter
forewith give notice of filing to Lender, setting forth any information
available to Borrower in its capacity as sublessee under the Sublease as to the
date of such filing, the court in which such petition was filed and the relief
sought therein. Borrower in its capacity as sublessee under the Sublease shall
promptly deliver to Lender following (i) filing, any and all notices, summonses,
pleadings, applications and other documents filed by Borrower in such capacity
with a court in connection with any such petition in any proceedings relating
thereto and (ii) receipt, any and all notices, summonses, pleadings,
applications and other documents received by Borrower in its capacity as
sublessee under the Sublease in connection with any such petition in any
proceedings relating thereto.

                                       33
<PAGE>

     J.   If there shall be filed by or against Borrower in any capacity a
petition under the Bankruptcy Code, and Borrower, as a sublessee under the
Sublease or any trustee of the Borrower, shall determine to reject the Sublease
pursuant to Section 365(a) of the Bankruptcy Code, then Borrower in its capacity
as sublessee under the Sublease shall give Lender not less than ten (10) days
prior written notice of the date on which Borrower shall apply to the Bankruptcy
Court for authority to reject the Sublease. In that event, within such ten (10)
day period, or in the event that no affirmative action to assume or reject the
Sublease pursuant to the Bankruptcy Code shall have been taken within thirty
(30) days after the date of filing of such petition, Lender shall have the
right, but not the obligation, to serve upon Borrower or such trustee a notice
stating that (i) Lender demands that Borrower in its capacity as sublessee under
the Sublease or such trustee assume and assign its subleasehold interest under
the Sublease to Lender pursuant to Section 365 of the Bankruptcy Code and (ii)
Lender covenants to cure or provide adequate assurance of prompt cure of all
defaults (except defaults of the types specified in Section 365(b)(2) of the
Bankruptcy Code) and provide adequate assurance of future performance of
Borrower's obligations under the Sublease. If Lender serves upon Borrower in its
capacity as sublessee under the Sublease or such trustee, the notice described
in the preceeding sentence, either Borrower nor trustee shall seek to reject the
Sublease and Borrower and such trustee shall seek court approval to comply with
the demand provided for in clause (i) of the preceding sentence within thirty
days after the notice shall have been given, subject to the performance by
Lender of the covenants provided for in clause (ii) of the preceding sentence.

     K.   Effective upon the entry of an order for relief in respect of Borrower
in any capacity under the Bankruptcy Code, Borrower in its capacity as sublessee
under the Sublease hereby assigns and transfers to Lender a non-exclusive right
to apply to the Bankruptcy Court under Section 365(d)(4) of the Bankruptcy Code
for an order extending the period during which the Sublease or Borrower's
subleasehold interest thereunder may be rejected or assumed.

     L.   In the event that the Sublease shall be amended or modified
(including, without limitation, obtaining the prior written consent of Lender as
required under this Security Deed) which amendment or modification shall be
evidenced by a supplement to the Sublease to be executed and a memorandum
thereof to be executed and recorded by the parties thereto, Borrower in its
capacity as sublessee of the Sublease shall simultaneously with the recordation
of the memorandum of the supplement to the Sublease execute and record an
amendment to this Security Deed reflecting changes required to make this
Security Deed consistent with the sublease, as so supplemented.

     24.  Intentionally Omitted.
          ---------------------

     25.  Intentionally Omitted.
          ---------------------

     26.  Notices. Except as otherwise specified in this Security Deed, any and
          -------
all notices, demands, elections or requests provided for or permitted to be
given pursuant to this Security Deed (hereinafter in this Paragraph referred to
as "Notice") shall be in writing and shall be deemed to have been properly given
or served by personal delivery or by sending same by overnight courier or by
depositing same in the United States Mail, postpaid and registered or

                                       34
<PAGE>

certified, return receipt requested, and addressed to the addresses set forth in
the commencement of this Security Deed. Each Notice shall be effective upon
being personally delivered or upon being sent by overnight courier or upon being
deposited in the United States Mail as aforesaid. However, the time period in
which a response to such Notice must be given or any action taken with respect
thereto, if any, shall commence to run from the date of receipt if personally
delivered or sent by overnight courier, or, if so deposited in the United States
Mail, the earlier of three (3) business days following such deposit and the date
of receipt as disclosed on the return receipt. Rejection or other refusal to
accept or the inability to deliver because of changed address for which no
Notice was given shall be deemed to be receipt of the Notice sent. By giving at
least thirty (30) days prior Notice thereof, Borrower or Lender shall have the
right from time to time and at any time during the term of this Security Deed to
change their respective addresses and each shall have the right to specify as
its address any other address within the United States of America.

     27.  Successors and Assigns Bound; Captions. The covenants and agreements
          --------------------------------------
herein contained shall bind, and the rights hereunder shall inure to, the
respective successors and assigns of Lender and Borrower, subject to the
provisions of Paragraph 6 hereof. The captions and headings of the paragraphs of
this Security Deed are for convenience only and are not to be used to interpret
or define the provisions hereof

     28.  Governing Law; Severability. This Security Deed and the obligations of
          ---------------------------
Borrower hereunder shall be governed by and interpreted and determined in
accordance with the laws of the Commonwealth of Massachusetts. In the event that
any provision or clause of this Security Deed or the Note conflicts with
applicable law, such conflict shall not affect other provisions of this Security
Deed or the Note which can be given effect without the conflicting provision,
and to this end, the provisions of this Security Deed and the Note are declared
to be severable. In the event that any applicable law limiting the amount of
interest or other charges permitted to be collected from Borrower is interpreted
so that any charge for which provision is made in this Security Deed or in the
Note, whether considered separately or together with other charges permitted to
be collected from Borrower, is interpreted so that any such charge, whether
considered separately or together with other charges that are considered a part
of the transaction represented by this Security Deed and the Note, violates such
law, and Borrower is entitled to the benefit of such law, such charge is hereby
reduced to the extent necessary to eliminate such violation. The amounts, if
any, previously paid to Lender in excess of the amounts payable to Lender
pursuant to such charges as reduced shall be applied by Lender to reduce the
principal of the indebtedness evidenced by the Note.

     29.  Discharge. Upon payment and performance of the Secured Obligations,
          ---------
Lender shall discharge this Security Deed. Borrower shall pay Lender's
reasonable costs incurred in discharging this Security Deed.

     30.  Waivers. Borrower agrees to the full extent permitted by law, that in
          -------
case of an Event of Default hereunder, neither Borrower nor anyone claiming
through or under Borrower shall or will set up, claim or seek to take advantage
of any appraisement, valuation, stay, extension, homestead, exemption or
redemption laws now or hereafter in force, in order to

                                       35
<PAGE>

prevent or hinder the enforcement or foreclosure of this Security Deed, or the
absolute sale of the Property, or the final and absolute putting into possession
thereof, immediately after such sale, of the purchasers thereat, and Borrower,
for Borrower and all who may at any time claim through or under Borrower, hereby
waives to the fullest extent that Borrower may lawfully so do, the benefit of
all such laws, and any and all right to have the assets comprised in the
security intended to be created hereby marshaled upon any foreclosure of the
lien hereof. No delay or omission of Lender or of any holder of the Note to
exercise any right, power or remedy accruing upon any Event of Default shall
exhaust or impair any such right, power or remedy or shall be construed to be a
waiver of any such default, or acquiescence therein; and every right, power and
remedy given by this Security Deed to Lender may be exercised from time to time
and as often as may be deemed expedient by Lender. No consent or waiver,
expressed or implied, by Lender to or of any Event of Default shall be deemed or
construed to be a consent or waiver to or of any other Event of Default. Failure
on the part of Lender to complain of any act or failure to act which constitutes
an Event of Default, irrespective of how long such failure continues, shall not
constitute a waiver by Lender of Lender's rights hereunder or impair any rights,
powers or remedies consequent on any Event of Default. No act or omission of
Lender as described in Paragraph 13 above shall preclude Lender from exercising
any right, power or privilege herein granted or intended to be granted in the
event of any Event of Default then made or of any subsequent Event of Default;
nor, except as otherwise expressly provided in an instrument or instruments
executed by Lender, shall the lien of this Security Deed be altered thereby. No
acceptance of partial payment or performance shall waive, affect or diminish any
right of Lender or Borrower's duty of compliance and performance therewith. Any
Obligation which this Security Deed secures is a separate instrument and may be
negotiated, extended or renewed by Lender without releasing Borrower or any
guarantor or co-maker. In the event of the sale or transfer by operation of law
or otherwise of all or any part of the Property, Lender, without notice, is
hereby authorized and empowered to deal with any such vendee or transferee with
reference to the Property or the Secured Obligations or with reference to any of
the terms, covenants, conditions or agreements hereof, as fully and to the same
extent as it might deal with the original parties hereto and without in any way
releasing or discharging any liabilities, obligations or undertakings
(including, without limitation, the restrictions upon transfer contained in
Paragraph 6).

     31.  Further Assurances. At any time and from time to time, upon request by
          ------------------
Lender, Borrower will make, execute and deliver, or cause to be made, executed
and delivered, to Lender and, where appropriate, cause to be recorded and/or
filed and from time to time thereafter to be re-recorded and/or re-filed, at
such time and in such offices and places as shall be deemed desirable by Lender,
any and all such other and further assignments, mortgages, security agreements,
financing statements, continuation statements, instruments of further assurance,
certificates and other documents as may, in the opinion of Lender, be necessary
or desirable in order to effectuate, complete, or perfect, or to continue and
preserve (a) the obligations of Borrower under this Security Deed, and (b) the
lien and security interest created by this Security Deed upon the Property. Upon
any failure by Borrower so to do, Lender may make, execute, record, file, re-
record and/or re-file any and all such assignments, mortgages, security
agreements, financing statements, continuation statements, instruments,
certificates, and

                                       36
<PAGE>

documents for and in the name of Borrower, and Borrower hereby irrevocably
appoints Lender as the agent and attorney in fact of Borrower so to do.

     32.  Subrogation. Lender shall be subrogated to all right, title, lien or
          -----------
equity of all persons to whom Lender may have paid any monies in settlement of
liens, charges or assessments, or in acquisition of title or for its benefit
hereunder, or for the benefit or account of Borrower upon execution of the Note
or subsequently paid under any provisions hereof.

     33.  Time of the Essence. Time is of the essence with respect to each and
          -------------------
every covenant, agreement and obligation of Borrower under this Security Deed,
the Note and any and all other Loan Documents.

     34.  Indemnification; Subrogation; Waiver of Offset.
          ----------------------------------------------

     (a)  Borrower shall indemnify, defend and hold Lender harmless against: (i)
any and all claims for brokerage, leasing, finders or similar fees which may be
made relating to the Property or the Secured Obligations, and (ii) any and all
liability, obligations, losses, damages, penalties, claims, actions, suits,
costs and expenses (including Lender's reasonable attorneys' fees, together with
reasonable appellate counsel fees, if any) of whatever kind or nature which may
be asserted against, imposed on or incurred by Lender in connection with the
Secured Obligations, this Security Deed, the Property, or any part thereof, or
the exercise by Lender of any rights or remedies granted to it under this
Security Deed; provided, however, that nothing herein shall be construed to
obligate Borrower to indemnify, defend and hold harmless Lender from and against
any and all liabilities, obligations, losses, damages, penalties, claims,
actions, suits, costs and expenses enacted against, imposed on or incurred by
Lender by reason of Lender's willful misconduct or gross negligence.

     (b)  If Lender is made a party defendant to any litigation or any claim is
threatened or brought against Lender concerning the Secured Obligations, this
Security Deed, the Property, or any part thereof, or any interest therein, or
the maintenance, operation or occupancy or use thereof, then Borrower shall
indemnify, defend and hold Lender harmless from and against all liability by
reason of said litigation or claims, including reasonable attorneys' fees
(together with reasonable appellate counsel fees, if any) and expenses incurred
