Sections 3.2(b), (c) or (d) above,  Escrowee shall be relieved of all liability,
responsibility  or  obligation  with  respect to or arising out of the escrow or
under this  Agreement.  Escrowee shall not be bound by any  modification to this

statements  contained in any notice,  instrument  or document or the accuracy or
due authorization of the execution of any notice, instrument or document.

Tests,  Purchaser  shall  restore the Premises to their  condition  prior to the
performance thereof.  Purchaser shall indemnify and hold harmless Seller and its

against any and all damages,  losses,  costs,  expenses,  liabilities and claims

Purchaser,  as the case may be, shall  promptly  remit to the other party hereto
any   amounts  to  which  such  party  shall  be  entitled  by  reason  of  such
recalculation.  Unmetered  water  charges or sewer rents  shall be adjusted  and
prorated as of the Closing Date.

     8.3. Other  Adjustments.  The following  items shall also be adjusted as of
11:59 P.M. on the date  preceding  the Closing  Date:  (i) charges and  payments
under Service Contracts  assigned to Purchaser;  (ii) charges and payments under
the JRC License Agreement;  and (iii) fees and payments,  if any, under Licenses
assigned to Purchaser.

     Any errors or omissions in computing  adjustments  at the Closing  shall be
promptly  corrected,  provided  that the party  seeking to correct such error or
omission  shall have  notified  the other  party of such error or omission on or
prior  to the  date  that  is one (1)  year  following  the  Closing  Date.  The
provisions of this Article 8 shall survive Closing.

     (a) Purchaser,  on the Closing Date, shall execute and deliver to Seller an
instrument by which Purchaser shall remake the representations  made pursuant to
Section  9.1  above  as  of  the  Closing,  provided  that  Purchaser,  in  such

reflect any discovered  inaccuracy therein,  such instrument being herein called
"PURCHASER'S REPRESENTATION CERTIFICATE".

     (b) Seller,  on the Closing Date, shall execute and deliver to Purchaser an
instrument  by which Seller shall remake the  representations  made  pursuant to
Sections 9.2 and 9.3 above as of the  Closing,  provided  that  Seller,  in such
instrument,  shall (i) update such  representations  to reflect events occurring
between the date hereof and the Closing and (ii) correct such representations to
reflect any discovered  inaccuracy therein,  such instrument being herein called
"SELLER'S  REPRESENTATION  CERTIFICATE".   Notwithstanding  the  foregoing,  (i)
Seller's Representation  Certificate shall remake the representations  contained
in Sections 9.3(b) hereof as to the Service  Contracts and (ii) Seller shall not
remake the representation contained in Sections 9.3(f)-(g) hereof.

     9.5. Remedies for Inaccuracies and Other Changes.

     (a)  The  remedies  of  Seller  and  Purchaser  for  an  inaccuracy  in any
representation  or for any update or  correction  set forth in any  Seller's  or
Purchaser's  Representation  Certificate  shall be  solely  as set  forth in the
following  provisions of this Section 9.5.  Each of Seller and Purchaser  hereby
waives any inaccuracy in, or any update made to, any  representation  made to it
pursuant to this Article 9, unless the same is Materially Adverse.  For purposes
of this Section  9.5, the term  "MATERIALLY  ADVERSE"  shall have the  following
meanings in the following contexts:

     (1) An  inaccuracy  in any  representation  by Seller shall be deemed to be
"MATERIALLY  ADVERSE" to Purchaser if, and only if (i) there is an inaccuracy in
such  representation  as of the  date  made and (ii)  Purchaser  may  reasonably
demonstrate  that such  inaccuracy  may  reasonably  be  expected to result in a
diminution  in the value of the Property or the  imposition  of  liability  upon
Purchaser which exceeds $25,000;

     (2) Facts  giving rise to an update or  correction  set forth in a Seller's
Representation  Certificate  shall  be  deemed  to be  "MATERIALLY  ADVERSE"  to
Purchaser if, and only if (i) such update or correction is not  contemplated  or
permitted  by the terms of this  Agreement  and (ii)  Purchaser  may  reasonably
demonstrate that such update or correction  results in a



diminution  in the value of the Property or the  imposition  of  liability  upon
Purchaser which exceeds $25,000; and

     (3) An inaccuracy in any  representation  by Purchaser or facts giving rise
to an update or correction set forth in a Purchaser's Representation Certificate
shall be deemed to be  "MATERIALLY  ADVERSE"  to Seller if, and only if,  Seller
reasonably  demonstrates that the same renders Purchaser incapable of proceeding
to Closing in accordance with the terms of this Agreement.

     (b) If, prior to Closing,  (i) Seller shall learn of an  inaccuracy  in any
representation  of Purchaser  set forth in Section 9.1 hereof (as made as of the
date hereof)  which is  Materially  Adverse to Seller,  which  inaccuracy is not
cured  within ten days after  notice from  Seller,  (ii) Seller shall know of an
inaccuracy  in any  representation  of Purchaser  made  pursuant to  Purchaser's
Representation  Certificate  (as made as of the  Closing)  which  is  Materially
Adverse  to Seller or (iii)  Purchaser's  Representation  Certificate  shall set
forth any update or  correction  which is  Materially  Adverse  to Seller,  then
Seller,  as its sole  remedy  therefor  in each  case,  shall  have the right to
terminate  this  Agreement  upon  notice to  Purchaser  at any time prior to the
Closing,  whereupon the Deposit shall be paid to Seller as liquidated damages on
account  thereof and  thereafter  neither  party  hereto  shall have any further
rights or obligations  hereunder  other than those which  expressly  survive the
termination  of this  Agreement.  Seller and Purchaser  agree that the aforesaid
liquidated  damages are a fair and reasonable amount to be retained by Seller as
agreed and liquidated  damages in light of Seller's removal of the Premises from
the market and the costs  incurred by Seller and shall not  constitute a penalty
or a forfeiture.  If, however, Seller proceeds to Closing in accordance with the
terms  hereof,  Seller shall be deemed to have waived the same and shall have no
claim on account thereof.  Notwithstanding  the foregoing,  if Seller terminates
this Agreement  pursuant to this Section 9.5(b) at any time on or before the Due
Diligence Expiration Date, the Initial Deposit shall be refunded to Purchaser.

     (c) If, prior to Closing, (i) Purchaser shall learn of an inaccuracy in any
representation  of Seller set forth in Sections 9.2 or 9.3 hereof (as made as of
the date hereof) which is Materially  Adverse to Purchaser,  which inaccuracy is
not cured within ten days after notice from Purchaser, (ii) Purchaser shall know
of an  inaccuracy  in any  representation  of Seller  made  pursuant to Seller's
Representation  Certificate (as made as of the Closing Date) which is Materially
Adverse to  Purchaser or (iii)  Seller's  Representation  Certificate  shall set
forth any update or correction  which is Materially  Adverse to Purchaser,  then
Purchaser,  as its sole remedy  therefor  in each case,  shall have the right to
terminate  this  Agreement  upon  notice to Seller at any time prior to Closing,
whereupon  the Deposit  shall be refunded to Purchaser  and  thereafter  neither
party shall have any further  rights or obligations  hereunder  other than those
which  expressly  survive  the  termination  of  this  Agreement.  If,  however,
Purchaser,  with actual knowledge of any such inaccuracy,  update or correction,
elects to proceed to Closing,  then Purchaser shall be deemed to have waived the
same and shall have no claim on account thereof.  Notwithstanding the foregoing,
if Purchaser  shall elect to terminate this  Agreement  pursuant to this Section
9.5(c) because Seller has (i) knowingly and intentionally (and with knowledge of
the  falsity  thereof)  made a  misrepresentation  or  false  warranty  or  (ii)
knowingly and intentionally caused a breach of representation or warranty, which
in either case is Materially Adverse to Purchaser, Purchaser



shall  have a claim for  damages  on  account  thereof  in the amount of actual,
out-of-pocket title examination and survey costs, third-party professional costs
(including  reasonable  attorneys'  fees and  disbursements)  and forfeited loan
application or commitment fees incurred in connection  with this Agreement,  not
to exceed $100,000 in the aggregate.

     (d) If, after Closing,  Purchaser shall first learn of an inaccuracy in any
representation  made by Seller pursuant to Seller's  Representation  Certificate
(as made as of the Closing Date),  then Purchaser shall have a claim for damages
on  account  thereof,  provided  that  (i) any  claim  not  brought  within  the
Representation  Survival  Period shall be deemed waived,  (ii) Purchaser  hereby
waives the right to collect or seek to collect consequential or punitive damages
and (iii) the inaccuracy is Materially Adverse to Purchaser.

                                ARTICLE 10. TITLE
                                -----------------

     10.1.  Acceptable Title. Seller shall convey, or cause to be conveyed,  and
Purchaser shall accept,  title to the Premises,  as of the Closing Date, subject
to the Permitted  Exceptions,  and otherwise free of all tenancies and rights to
possession and in broom clean condition.  The term "PERMITTED  EXCEPTIONS" shall
mean, collectively,  (i) the matters set forth in Exhibit K annexed hereto, (ii)
Title  Exceptions  that Title  Insurer shall be willing to omit as exceptions to
coverage in any owner's or mortgagee's  policy of title insurance obtained by or
on behalf of Purchaser and (iii) any  exceptions  and matters that are approved,
waived or deemed to have been approved or waived by Purchaser.

     10.2. Inability to Convey Acceptable Title. Purchaser agrees to obtain from
Title  Insurer,  at  Purchaser's  expense,  a title  report with  respect to the
Premises (the "TITLE REPORT"). Purchaser shall furnish Seller with a copy of the
Title  Report  promptly  after its receipt  thereof,  but in no event later than
twenty-five days after the Effective Date. On or before the date which is thirty
(30) days after the Effective  Date (TIME BEING OF THE  ESSENCE),  Purchaser may
furnish Seller with written notice (a "TITLE  OBJECTION  NOTICE") of those Title
Exceptions  (hereinafter  defined)  noted  in the  Title  Report  which  are not
Permitted Exceptions and as to which Purchaser objects. In addition, within five
days of Purchaser's  receipt of any continuation of the Title Report,  Purchaser
may furnish Seller with written notice of Title  Exceptions  noted therein which
are not Permitted  Exceptions and as to which Purchaser  objects,  provided such
Title  Exceptions were not noted in the Title Report (or any prior  continuation
thereof).  Any such  notice  shall also  constitute  a Title  Objection  Notice.
Purchaser shall be deemed to have waived objection to Title Exceptions set forth
in the Title Report (or any  continuation  thereof) to which timely objection is
not made in a Title Objection Notice.  For purposes of this Agreement,  the term
"TITLE EXCEPTIONS" shall mean any lien, encumbrance,  security interest, charge,
reservation, lease, tenancy, easement, right-of-way,  encroachment,  restrictive
covenant,  condition or limitation or other matter adversely  affecting title to
the Property.

     10.3. Seller's Rights. Seller shall have the right, in its sole discretion,
upon notice to Purchaser  (the "TITLE  RESPONSE  NOTICE")  given within ten (10)
days after  Seller's  receipt of any Title  Objection  Notice (TIME BEING OF THE
ESSENCE), to elect to either (i) take such action



as Seller  deems  advisable to discharge  those Title  Exceptions  which are not
Permitted Exceptions and are set forth in the Title Objection Notice (the "TITLE
DEFECTS") or (ii) subject to the  provisions  of Section 10.4 hereof,  terminate
this  Agreement,  whereupon  the  Deposit  shall be refunded  to  Purchaser  and
thereafter  neither party hereto shall have any further  obligation to the other
party hereto,  with the exception of those  obligations  which expressly survive
the termination of this  Agreement.  If Seller fails timely to deliver the Title
Response  Notice,  then Seller shall be deemed to have elected to terminate this
Agreement  pursuant  to clause  (ii)  above.  If Seller,  in its Title  Response
Notice,  elects to take  action  to  remove,  remedy  or  comply  with the Title
Defects,  Seller shall be entitled to one or more  adjournment(s) of the Closing
for up to thirty days in the aggregate to discharge the Title Defects,  provided
that such  adjournment  shall not  result in the  forfeiture  of any  commitment
obtained  by  Purchaser  to finance  its  acquisition  of the  Property,  unless
Purchaser  may  extend the time in which to close the loan  contemplated  by the
commitment at no cost to Purchaser (it being agreed that the foregoing shall not
be deemed to  constitute a financing  contingency).  If Seller elects to adjourn
the Closing as aforesaid,  Seller shall thereafter use  commercially  reasonable
efforts to remove,  remedy or comply with the Title Defects. If Seller is unable
to remove,  remedy or comply with such Title  Defects at the  expiration of such
adjournment(s),  then this Agreement  shall be deemed to be terminated as of the
last  adjourned  date of Closing.  Upon such  termination,  the Deposit shall be
refunded to Purchaser and neither party hereto shall have any further obligation
to the other party,  with the  exception of those  obligations  which  expressly
survive the termination of this  Agreement.  Except as set forth in Section 10.5
hereof,  nothing in this Agreement  shall be deemed to require Seller to take or
bring any  action or  proceeding  or any other  steps to remove any defect in or
objection to title or to expend any moneys  therefor,  nor shall  Purchaser have
any right of action against Seller, at law or in equity, therefor.

     10.4. Purchaser's Right to Accept Title. Purchaser may, upon written notice
to Seller at any time on or before the  Closing  Date (as the same may have been
adjourned by Seller in accordance  with the  provisions of Section 10.3 hereof),
elect to accept such title as Seller can convey,  notwithstanding  the existence
of any Title Defects.  In such event,  (i) this Agreement  shall remain in force
and effect,  (ii) the parties shall proceed to Closing and (iii) Purchaser shall
not be entitled to any abatement of the Purchase Price,  any credit or allowance
of any kind or any  claim or right of  action  against  Seller  for  damages  or
otherwise by reason of the Title Defects.

     10.5.  Seller's  Obligation.  Notwithstanding  anything  contained  in this
Article 10 the contrary,  Seller shall at or prior to Closing  discharge (i) any
mortgage affecting the Property,  (ii) any Title Defects which are knowingly and
intentionally  created  by Seller  subsequent  to the date  hereof and (iii) any
Title Defects  which may be discharged  solely by the payment of a sum of money,
not to exceed $200,000 in the aggregate.

     10.6.  Wentworth  Deed.  Seller has  furnished  Purchaser  with a copy of a
mortgagee  policy  of title  insurance  for the  Premises,  issued  by  Fidelity
National  Title,  dated October 22, 1998.  Such policy raises an exception  from
coverage for a  reservation  of right of way  contained in a deed dated July 11,
1927 by E. Francis  Wentworth,  et al, to Samuel R. Wentworth,  recorded in Deed
Book 1956, Page 301,  Norfolk County Records (the "WENTWORTH  DEED").  Purchaser
reserves the right to raise  objection to the Wentworth Deed in accordance  with
the provisions of



Section 10.2 hereof,  whereupon  Seller and Purchaser  shall have the rights and
remedies accorded to them by this Article 10 with respect to Title Exceptions to
which Purchaser has raised objection in a Title Objection  Notice.  If Purchaser
fails to  raise  object  to the  Wentworth  Deed in the  time and in the  manner
specified  in Section  10.2  hereof,  Purchaser  shall be deemed to have  waived
objection  thereto,  in which event  Purchaser shall close title to the Premises
subject thereto without abatement of the Purchase Price,  credit or allowance of
any kind or claim or right of action  against Seller for damages or otherwise by
reason of the  Wentworth  Deed.  Nothing  in this  Agreement  shall be deemed to
require  Seller to take or bring any action or  proceeding or any other steps to
obtain the discharge of the Wentworth Deed.

     10.7.  Title  Insurance.  Purchaser and Seller shall  cooperate  with Title
Insurer and each other in connection  with obtaining  title  insurance  insuring
title to the Premises  subject to the Permitted  Exceptions.  In furtherance and
not in limitation of the  foregoing,  Seller shall deliver to Title Insurer such
certificates  or resolutions as may be required to obtain the recordation of the
Deed or any instrument  required to discharge any Title Exception which is not a
Permitted  Exception.  In addition,  Seller  shall  execute and deliver to Title
Insurer an Indemnity Agreement in the form annexed hereto as Exhibit L.

     10.8. Violations.  Seller shall have no responsibility to cure, or cause to
be cured, any violations of Requirements noted against the Premises, whether the
same have  been  noted or  issued  as of the date  hereof or are first  noted or
issued  after  the date  hereof,  and  Purchaser  agrees  to close  title to the
Premises subject thereto.

                      ARTICLE 11. CASUALTY AND CONDEMNATION
                      -------------------------------------

          11.1. Casualty.

     (a) For  purposes of this  Article 11, the  following  terms shall have the
meanings indicated:

     "MAJOR  CASUALTY"  means a fire in or other  casualty to the Premises which
causes  damage or injury to the  Premises  and results in  Restoration  Costs in
excess of an amount equal to ten percent (10%) of the Purchase Price.

     "RESTORATION  COSTS"  means the cost to repair or  restore  (as  reasonably
determined  by an  architect  or  engineer  selected  by Seller and  approved by
Purchaser,  which approval shall not be  unreasonably  withheld,  conditioned or
delayed) the damage to the Premises caused by a fire or other casualty.

     (b) If,  between the date hereof and the Closing,  there shall occur a fire
or other  casualty  affecting the Premises which is not a Major  Casualty,  then
Purchaser shall have no right to terminate this Agreement and shall purchase the
Premises in its damaged  condition  without  reduction of or offset  against the
Purchase  Price or any  other  claim  against  Seller.  Seller  shall  assign to
Purchaser  the right to receive any  insurance  proceeds  payable to Seller as a
result of



such fire or other casualty; provided, however, that Seller shall be entitled to
retain (to the extent theretofore paid to Seller), and shall not be obligated to
assign the right to receive  (to the extent not  theretofore  paid to Seller) an
amount of such insurance proceeds equal to Seller's reasonable expenses, if any,
incurred in collecting  such proceeds and repairing the damage caused by fire or
other casualty and provided further that Purchaser shall be entitled to a credit
against  the Cash  Balance in an amount  equal to any  portion of the  insurance
claim not payable by reason of the existence of a deductible in Seller's  policy
of casualty insurance.

     (c) If,  between the date hereof and the Closing,  there shall occur a fire
or  other  casualty  affecting  the  Premises  which is a Major  Casualty,  then
Purchaser  shall have the option,  to be exercised  upon notice to Seller within
fifteen (15) days after  receiving  notice of such  casualty,  to terminate this
Agreement. If Purchaser shall so elect to terminate this Agreement,  the Deposit
shall be refunded to  Purchaser,  whereupon  neither party hereto shall have any
further  obligation to the other hereunder,  except for those  obligations which
expressly  survive the  termination of this  Agreement.  If Purchaser  shall not
elect to terminate  this  Agreement as provided in this subclause (c), then this
Agreement  shall remain in full force and effect and the  provisions  of Section
11.1(b) above shall apply to such damage and any insurance  proceeds  payable in
connection therewith.

     (d) In no event shall  Seller have any  obligation  to repair any damage or
destruction  to the  Premises,  but  Seller  shall  have the  right to do so and
utilize insurance proceeds for such purpose.

     (e) Seller and  Purchaser  expressly  intend  that the  provisions  of this
Section 11.1 shall govern in the event of a fire or other casualty.

     11.2. Condemnation.

     (a) If,  between  the date  hereof and the  Closing,  any  condemnation  or
eminent  domain  proceedings  are  initiated  which  would  result in a material
taking, then either Seller or Purchaser may elect to terminate this Agreement by
giving  written  notice of its election to the other party  within  fifteen (15)
days after receiving notice of such prospective  taking.  If Seller or Purchaser
shall so elect to terminate  this  Agreement,  the Deposit  shall be refunded to
Purchaser,  whereupon neither party hereto shall have any further  obligation to
the other hereunder,  except for those  obligations  which expressly survive the
termination  of this  Agreement.  If neither  party so elects to terminate  this
Agreement,  then  the  parties  hereto  shall  proceed  to the  Closing  without
reduction of or offset  against the Purchase  Price and Purchaser  shall have no
other claim against  Seller.  In such event,  all of Seller's  right,  title and
interest  in and to any  condemnation  proceeds  paid or payable  in  connection
therewith shall be assigned to Purchaser.

     (b) If,  between  the date  hereof and the  Closing,  any  condemnation  or
eminent domain  proceedings  are initiated  which would not result in a material
taking,  then neither  Seller nor Purchaser may terminate this Agreement and the
parties shall proceed to the Closing without  reduction of or offset against the
Purchase Price and Purchaser shall have no other claim against  Seller.  In such
event,  all of Seller's  right,  title and  interest in and to any  condemnation
proceeds paid or payable in connection therewith shall be assigned to Purchaser.



     (c) For  purposes of this  Section  11.2,  a taking shall be deemed to be a
material  taking if it would  result in the  taking of in excess of (i)  percent
(10%) of the rentable  square  footage of the Building or (ii) five percent (5%)
of the parking  spaces  located on the Land.  In no event shall  Seller have any
obligation to repair or restore the Premises or any portion thereof by reason of
any condemnation, whether material or otherwise.

                        ARTICLE 12. DEFAULT AND REMEDIES
                        --------------------------------

     12.1.  Default By  Purchaser.  If  Purchaser  (i)  defaults  in its Closing
obligations (i.e., defaults in the payment of the Purchase Price or otherwise in
the  performance of any of its  obligations  hereunder which are to be performed
on, or as of, the Closing Date) or (ii) otherwise  materially defaults hereunder
and such other  material  default is not cured within ten (10) days after notice
thereof from Seller to Purchaser,  then, and in any of such events,  Seller,  as
its sole remedy  therefor,  may terminate  this  Agreement by written  notice to
Purchaser,  whereupon the Deposit shall be paid to Seller as liquidated  damages
on  account of such  default,  and,  thereafter,  neither  party  shall have any
further rights or obligations hereunder other than those which expressly survive
the termination of this Agreement. Seller and Purchaser agree that the aforesaid
liquidated  damages are a fair and reasonable amount to be retained by Seller as
agreed and liquidated  damages in light of Seller's removal of the Premises from
the market and the costs  incurred by Seller and shall not  constitute a penalty
or a  forfeiture.  Except as expressly  provided to the contrary in this Section
12.1,  Seller  waives any other right or remedy which Seller may have, at law or
in equity, by reason of a default by Purchaser hereunder.

     12.2. Default By Seller. If Seller (i) defaults in its Closing  obligations
(i.e., defaults in the performance of any of its obligations hereunder which are
to be performed  on, or as of, the Closing  Date) or (ii)  otherwise  materially
defaults  hereunder and such material  default is not cured within ten (10) days
after notice thereof from  Purchaser to Seller,  then, and in either such event,
Purchaser  may,  as its sole  remedy  therefor,  either (x) pursue an action for
specific  performance of this Agreement by Seller hereunder,  without abatement,
credit  against  or  reduction  of the  Purchase  Price  or (y)  terminate  this
Agreement by written  notice to Seller,  whereupon the Deposit shall be refunded
to Purchaser; it being understood and agreed that in no event shall Purchaser be
entitled  to money  damages.  If  Purchaser  shall  elect to so  terminate  this
Agreement,  then, except as set forth in Section 12.3 below, neither party shall
have any  further  rights  or  obligations  hereunder  other  than  those  which
expressly  survive  the  termination  of this  Agreement.  Except  as  expressly
provided in this Section 12.2,  Purchaser  waives any other right or remedy,  at
law or in equity,  which Purchaser may have or be entitled to as a result of any
default by Seller.

     12.3. Reimbursement of Purchaser. Notwithstanding the provisions of Section
12.2 hereof,  if Purchaser  terminates  this Agreement  pursuant to Section 12.2
hereof  because  Seller  knowingly  and  intentionally  defaulted,   beyond  any
applicable  notice and cure period,  in the performance of any material covenant
of Seller hereunder, Purchaser shall have a claim for damages on account thereof
in the amount of  actual,  out-of-pocket  title  examination  and survey  costs,
third-party   professional  costs  (including  reasonable  attorneys'  fees  and
disbursements) and



forfeited loan  application or commitment  fees incurred in connection with this
Agreement, not to exceed $100,000 in the aggregate.

                               ARTICLE 13. BROKER
                               ------------------

     13.1. Broker.  Seller and Purchaser each represent and warrant to the other
that each has had no  conversations  or  dealings  with any  broker or finder in
connection  with  the  transactions  contemplated  hereby,  other  than  Broker.
Purchaser and Seller (each, an "INDEMNIFYING PARTY") shall indemnify, defend and
hold the other  harmless  from and  against  any and all loss,  cost or  expense
(including, without limitation, reasonable attorneys' fees) arising by reason of
a claim for a commission or other compensation made by a broker or finder (other
than Broker)  claiming to have dealt with the Indemnifying  Party.  Seller shall
pay any commission due to Broker pursuant to separate  written  agreements.  The
provisions of this Article 13 shall survive  Closing or any  termination of this
Agreement.

                             ARTICLE 14. ASSIGNMENT
                             ----------------------

     14.1. No Assignment  by  Purchaser.  Neither this  Agreement nor any of the
rights of Purchaser hereunder (nor the benefits of such rights) may be assigned,
transferred or encumbered  without Seller's prior written consent (which consent
may be withheld in Seller's  sole and  absolute  discretion)  and any  purported
assignment, transfer or encumbrance without Seller's prior written consent shall
be void.  Purchaser  expressly  covenants  and agrees that (a) if Purchaser is a
corporation,  a sale or transfer  of more than fifty  (50%)  percent (at any one
time or in the  aggregate  from time to time) of the  shares of any class of the
issued and  outstanding  stock of Purchaser,  its successors or assigns,  or the
issuance  of  additional  shares of any class of its stock to the extent of more
than fifty  (50%)  percent  (at any one time or, in the  aggregate  from time to
time) of the number of shares of said class of stock issued and  outstanding  on
the date hereof,  (b) if Purchaser is a  partnership,  joint  venture or limited
liability  company,  a sale or transfer of more than fifty (50%) percent (at any
one  time or in the  aggregate  from  time to time)  of the  partnership,  joint
venture or membership interests of Purchaser,  its successors or assigns, or the
issuance of additional partnership, joint venture or membership interests of any
class to the extent of more than fifty (50%)  percent (at any one time or in the
aggregate  from time to time) of the  amount of  partnership,  joint  venture or
membership  interests  issued  on the  date  hereof  shall,  in any  such  case,
constitute an assignment of this Agreement.  Unless, in each instance, the prior
written  consent  of  Seller  has  been  obtained,  any  such  assignment  shall
constitute a material  default under this  Agreement and shall entitle Seller to
exercise all rights and remedies under this Agreement,  at law or equity, in the
case of such a default.

     14.2. Permitted Assignment to Affiliate.  Notwithstanding the provisions of
Section 14.1 above to the contrary,  the named Purchaser in this Agreement shall
have the  one-time  right to  assign  its  rights  and  obligations  under  this
Agreement  to either (i) an  Affiliate  of such  named  Purchaser  (including  a
Massachusetts  nominee  trust  constituting  an Affiliate of  Purchaser) or (ii)
Matthew Israel,  Purchaser's  executive  director,  in each case effective on or
prior to the Closing,



provided that, on or prior to the effective date of such assignment,  (i) in the
case of an assignment to an Affiliate,  Purchaser delivers to Seller evidence of
the ownership of Purchaser  and the proposed  assignee so as to permit Seller to
verify  that such  proposed  assignee  is an  Affiliate  of  Purchaser  and (ii)
Purchaser  delivers  to  Seller  a  written   assumption,   in  form  reasonably
satisfactory to Seller and duly executed and  acknowledged  by the assignee,  in
which the assignee agrees to assume all of Purchaser's covenants, agreements and
obligations  under  this  Agreement.  As of the date of the  assignment  of this
Agreement to an  Affiliate or to Mr.  Israel in  accordance  with the  foregoing
provisions of this Section 14.2, the  representations  of Purchaser named herein
set forth in  Section  9.1  hereof  shall be remade as to the  Affiliate  or Mr.
Israel, as the case may be, except that the  representations  and warranties set
forth in Section 9.1(a) hereof shall be modified  accordingly.  Purchaser  named
herein shall remain fully liable for all of  Purchaser's  covenants,  agreements
and  obligations  under  this  Agreement   notwithstanding  any  such  permitted
assignment  pursuant to this Section 14.2. Upon any assignment of this Agreement
in accordance  with the provisions of this Article 14,  Purchaser shall promptly
pay to Seller any  consideration  paid or payable to  Purchaser by reason of the
assignment.

                              ARTICLE 15. COVENANTS
                              ---------------------

     15.1. Operation of Premises.  Between the date hereof and the Closing Date,
Seller  shall  continue to maintain  the  Premises  in the  ordinary  course and
substantially  in  accordance  with the  practices  and  procedures  customarily
followed by Seller in the  maintenance of the Premises prior to the date hereof;
provided,  however,  that Seller shall have no obligation to make any repairs or
expenditures that are capital in nature.

     15.2. Capital Repairs.

     (a) Between the date hereof and the Closing Date, Seller shall not make any
material  capital  repairs or  replacements  to the  Premises  without the prior
written consent of Purchaser,  which consent shall not be unreasonably  withheld
or  delayed,  provided,  however,  that  Seller may  undertake  such  repairs or
replacements  without Purchaser's consent if (i) the performance of such repairs
or replacements is required to avoid an unsafe or hazardous condition,  (ii) the
performance  of  such  repairs  or  replacements  is  required  pursuant  to any
Requirements  or (iii) Seller's  failure to perform such repairs or replacements
would,  in Seller's  reasonable  judgment,  subject  Seller to criminal or civil
liability or result in a forfeiture of the Property or the  imposition of a lien
or  encumbrance  thereon.  Whenever  required  pursuant  to this  Section  15.2,
Purchaser's consent shall be deemed granted if not denied by notice (stating the
grounds for denial with reasonable  specificity) given to Seller within five (5)
Business  Days of  Purchaser's  receipt from Seller of request for such consent.
Whenever  Purchaser's consent to a capital repair or replacement is not required
pursuant to this Section 15.2,  Seller shall furnish  Purchaser with  reasonable
prior notice of the repair or  replacement,  except in the case of an emergency,
in which case Seller shall furnish  Purchaser with such notice as is practicable
under the circumstances.

     (b) Seller and Purchaser  acknowledge  that Seller  anticipates  engaging a
contractor or  contractors to perform  repair work upon an  approximately  1,080
square foot portion



of the facade (the "FACADE WORK").  Purchaser hereby consents to the performance
of the Facade Work and to Seller's  entrance  into such contract as Seller deems
appropriate  for the performance of the Facade Work  (collectively,  the "FACADE
WORK  CONTRACT").  If the Facade Work is not  completed on or before the Closing
Date,  then,  at Closing,  (i) Seller shall assign to Purchaser  all of Seller's
right, title and interest in and to the Facade Work Contract and Purchaser shall
assume all of Seller's obligations  thereunder in accordance with the provisions
of the Service  Contract  Assignment and (ii)  Purchaser  shall be entitled to a
credit  against the Cash  Balance in an amount  equal to the  remaining  balance
under the Facade Work Contracts. If the Facade Work is completed before Closing,
Seller shall at Closing  assign to Purchaser any  warranties  by the  contractor
under the Facade Work Contract.

     15.3. Insurance. Between the date hereof and the Closing Date, Seller shall
either  (i)  maintain  in full  force and  effect  the fire and  other  casualty
insurance  coverages  described in Exhibit J annexed hereto or (ii) replace such
insurance policies with other policies providing coverage equivalent thereto.

     15.4.  Leases.  Between the date hereof and the Closing Date,  Seller shall
not enter into any lease,  license or  occupancy  agreement  with respect to the
Premises.

     15.5.  Service  Contracts.  Between the date  hereof and the Closing  Date,
Seller shall not enter into any New Service Contracts or modify, renew or extend
the term of any of the  Existing  Service  Contracts  or New  Service  Contracts
without Purchaser's prior written consent in each instance,  which consent shall
not be unreasonably withheld,  conditioned or delayed. If required,  Purchaser's
consent shall be deemed granted if not denied by notice (stating the grounds for
denial with  reasonable  specificity)  given to Seller  within five (5) Business
Days  of   Purchaser's   receipt  from  Seller  of  request  for  such  consent.
Notwithstanding anything contained in this Section 15.4 to the contrary,  Seller
shall have the right,  without Purchaser's consent, to terminate any one or more
of the Existing Service  Contracts and the New Service  Contracts at any time on
or prior to the Closing Date.

     15.6.  Notices.  Seller shall promptly furnish Purchaser with copies of any
written notices Seller receives from  governmental  authorities which pertain to
the Premises.

                            ARTICLE 16. MISCELLANEOUS
                            -------------------------

     16.2.  Governing Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the Commonwealth of Massachusetts.

     16.3. Successors. All of the provisions of this Agreement and of any of the
documents and instruments  executed in connection herewith shall apply to and be
binding upon, and inure to the benefit of Seller and Purchaser, their successors
and their permitted assigns.

     16.4. No Third Party Beneficiary. This Agreement and each of the provisions
hereof are solely for the benefit of  Purchaser  and Seller and their  permitted
assigns.  No  provisions  of  this  Agreement  or of any of  the  documents  and
instruments  executed in connection  herewith  shall be construed as creating in
any person or entity other than Purchaser and Seller and their permitted assigns
any rights of any nature whatsoever.

     16.5. No Personal  Liability.  Purchaser shall look only to Seller's estate
and  interest  in the  Property  for the  collection  of a  judgement  (or other
judicial  process)  requiring  the  payment of money by Seller in the event that
Purchaser is expressly entitled to a damage claim against Seller pursuant to the
terms of this  Agreement,  and no other  property  or  assets  of  Seller or its
partners, members, officers, managers, shareholders or principals,  disclosed or
undisclosed,   shall  be  subject  to  levy,  execution,   attachment  or  other
enforcement  procedure  for the  satisfaction  of any such damage claim  against
Seller under or with respect to this Agreement. The foregoing provisions of this
Section  are not  intended  to,  and shall  not,  limit any  express  right that
Purchaser might



otherwise  have to obtain  equitable  relief  (including  the remedy of specific
performance  where  applicable and  appropriate)  against Seller.  The terms and
provisions  of  this  subsection  shall  survive  the  Closing  or  the  earlier
termination of this Agreement.

     16.6.  Entire  Agreement.  This Agreement,  together with the documents and
instruments executed and delivered in connection herewith,  set forth the entire
agreement between Purchaser and Seller relating to the transactions contemplated
hereby  and all  other  prior  or  contemporaneous  agreements,  understandings,
representations  or  statements,  oral  or  written,  relating  directly  to the
Property are superseded hereby.

     16.7. Severability.  If any provision in this Agreement is found by a court
of competent  jurisdiction to be in violation of any applicable law, and if such
court should  declare such  provision  of this  Agreement to be unlawful,  void,
illegal or unenforceable  in any respect,  the remainder of this Agreement shall
be construed as if such unlawful,  void, illegal or unenforceable provision were
not contained therein, and the rights,  obligations and interests of the parties
hereto under the remainder of this  Agreement  shall  continue in full force and
effect undisturbed and unmodified in any way.

     16.8. Modification. This Agreement and the terms hereof may not be changed,
waived, modified,  supplemented,  canceled, discharged or terminated orally, but
only by an instrument or instruments in writing executed and delivered by Seller
and Purchaser.

     16.9.  Waiver of Trial by Jury.  EACH PARTY HEREBY WAIVES,  IRREVOCABLY AND
UNCONDITIONALLY,  TRIAL BY JURY IN ANY ACTION  BROUGHT ON, UNDER OR BY VIRTUE OF
OR RELATING IN ANY WAY TO THIS AGREEMENT OR ANY OF THE DOCUMENTS OR CERTIFICATES
EXECUTED IN CONNECTION HEREWITH, THE PROPERTY, OR ANY CLAIMS,  DEFENSES,  RIGHTS
OF SET-OFF OR OTHER ACTIONS PERTAINING HERETO OR TO ANY OF THE FOREGOING.

     16.10.  Venue.  Purchaser  and Seller  each hereby  irrevocably  waives any
objection  that it may now or hereafter have to the laying of venue of any suit,
action  or  proceeding  arising  out  of  this  Agreement  or  the  transactions
contemplated  hereby  brought  in any  federal  or state  court  sitting  in the
Commonwealth of Massachusetts  and hereby further  irrevocably  waives and claim
that any such  suit,  action or  proceeding  brought  in any such court has been
brought in an inconvenient  forum. Seller and Purchaser further hereby expressly
submits to the  jurisdiction  of all  federal  and state  courts  sitting in the
Commonwealth of Massachusetts.

     16.11. No Recording. Neither this Agreement nor any memorandum hereof shall
be recorded.  Each party hereby agrees to indemnify and hold harmless the others
for all liabilities,  losses,  damages, liens, suits, claims, costs and expenses
(including  reasonable  attorneys'  fees)  incurred by the others by reason of a
breach of the foregoing covenant.

     16.12.  Captions.  The captions and table of contents in this Agreement are
inserted for  convenience  of reference  only and in no way define,  describe or
limit the scope or intent of this Agreement or any of the provisions hereof.



     16.13.  Counterparts;  Effectiveness  of Agreement.  This  Agreement may be
executed  in any  number of  counterparts,  each of which  shall  constitute  an
original  but  all of  which  together  will  constitute  one  instrument.  This
Agreement shall not be effective unless and until the same has been executed and
delivered by all parties hereto whether in one or more counterparts.

     16.14.  Merger.  The delivery of the Deed to  Purchaser  and the closing of
title to the  Property  shall be  deemed  to  constitute  full  performance  and
discharge by Seller of every  agreement and  obligation on the part of Seller to
be performed hereunder, and no agreement,  promise,  representation or warranty,
express or implied, on the part of Seller shall survive Closing unless expressly
set forth to the contrary herein.

     16.15.  Fair  Interests.  The parties  acknowledge  that each party and its
counsel have reviewed this Agreement and the rule of  construction to the effect
that any ambiguities are to be resolved  against the drafting party shall not be
employed in the interpretation of this Agreement.

     16.16.  Legal Fees.  If either  party brings any action or suit against the
other by reason of any default under this  Agreement,  the prevailing  party, as
finally determined in such action or suit, shall be entitled to recover from the
other party all costs and expenses of such action or suit  (including  appellate
proceedings),  including,  without  limitation,  reasonable  attorneys' fees and
disbursements,  it being  agreed  that the  determination  of which party is the
prevailing  party shall be included in the matters which are the subject of such
action or suit.

     16.17. Time is of the Essence. Time shall be of the essence with respect to
the obligations of Seller and Purchaser hereunder.



     IN WITNESS  WHEREOF,  the parties hereto have executed this Agreement as of
the date first above written.
