    8.   Due Diligence Contingency.  

    (a)  Conditions. Prior to the execution hereof, SELLER has delivered to
         BUYER copies of documents, reports, financial information and
         materials relating to the Real Property (the "SELLER'S Due Diligence
         Materials"). BUYER'S obligation to consummate the transaction
         contemplated by this Agreement is subject to the conditions of this
         Paragraph 8.  For purposes of this Agreement, the term "Inspection
         Period" shall mean the period ending on July 25, 1997 (the "Inspection
         Period Expiration Date").  

    (b)  Tests, Investigations and Inspections.  During the Inspection Period,
         BUYER, its agents and representatives, may, subject to the terms of
         this Agreement, enter upon the Premises upon reasonable prior notice
         to SELLER or SELLER'S designee, as specified in a written notice from
         SELLER to BUYER, to perform such investigations, inspections and tests
         of the Premises at BUYER'S sole expense, as BUYER deems necessary,
         including boundary surveys, Phase I environmental studies,
         examinations and tests of all structural and mechanical systems within
         the Improvements, and to go to SELLER'S offices to examine the books
         and records of SELLER, speak with SELLER'S property managers who
         SELLER will make reasonably available to BUYER, to review the Due
         Diligence Materials relating to the Premises, to examine title and
         compliance of the Premises with all governmental regulation and
         control and to determine in any and all other respects BUYER deems
         necessary and appropriate whether BUYER is satisfied with all aspects
         of the Premises for the purpose of purchasing the same (collectively
         the "Due Diligence").

         Notwithstanding BUYER's right to receive other of SELLER'S Due
         Diligence Materials provided for in this agreement, contemporaneously
         with the execution of this agreement and on an on-going basis until
         the Closing Date SELLER or SELLER'S representatives shall deliver to
         BUYER any Environmental Documents,

                                      3



         as hereinafter defined, concerning the Premises, which are in 
         SELLER'S possession, custody or control. "Environmental 
         Documents" shall mean all environmental documentation in the 
         possession or under the control of SELLER concerning the 
         Premises, or its environs, including without limitation, all 
         sampling plans, cleanup plans, preliminary assessment plans and 
         reports, site investigation plans and reports, remedial 
         investigation plans and reports, remedial action plans and 
         reports, or the equivalent, sampling results, sampling result 
         reports, data, diagrams, charts, maps, analysis, conclusions, 
         quality assurance/quality control documentation, correspondence 
         to or from any Governmental Authority (as defined immediately 
         below)(such as submissions to any Governmental Authority and 
         directives, orders, approvals and disapprovals issued by any 
         Governmental Authority).  A "Governmental Authority" is any 
         agency, board, bureau, commission, department or body of any 
         municipal, county, state or federal governmental unit, or any 
         subdivision thereof, having, asserting or acquiring jurisdiction 
         over all or any part of the Premises or the management, 
         operation, use or improvement thereof.  SELLER makes no 
         representation as to accuracy, completeness or right to rely on 
         the Environmental Documents or contents thereof; provided, 
         however, to the best of SELLER'S knowledge and belief, to the 
         extent copies of any documents, materials, inspections, or 
         reports were furnished by SELLER to BUYER, they were true, 
         accurate and complete representations of the same as contained in 
         SELLER'S files in all material respects..

         Notwithstanding anything herein contained to the contrary, BUYER shall
         not perform any "so-called" invasive tests, such as a Phase II, to the
         land or improvements comprising the Premises without SELLER'S advance
         written approval, which shall not be unreasonably withheld or delayed;
         provided that BUYER notifies SELLER of its intent to perform such
         tests at least three (3) business days in advance describing in
         reasonable detail the tests to be performed and permits SELLER or its
         representative to be present for such tests. In addition, in the event
         that SELLER or SELLER'S representatives shall have cause to meet with
         the Department of Environmental Protection (up to the Closing Date),
         SELLER shall immediately notify BUYER, and BUYER and BUYER's
         representatives shall have the right, without obligation, to attend
         and participate in all such meetings.

    (c)  In furnishing SELLER'S Due Diligence Materials, to the extent
         documents, inspections, copies, reports, materials or information were
         furnished by or obtained from third parties, SELLER neither warrants
         nor represents the accuracy of the information and data contained
         therein, nor the right of BUYER to rely thereon. In the event that
         BUYER shall terminate this Agreement, BUYER shall deliver to SELLER,
         immediately upon BUYER obtaining same, and SELLER shall be entitled to
         retain in any event, complete copies of all studies, investigations,
         test results, information and the like obtained by BUYER during the
         Due Diligence Period ("BUYER'S Due Diligence Materials"); provided,
         however, BUYER shall not be required to deliver to SELLER any such

                                       4



         BUYER'S Due Diligence Materials not received by BUYER from the parties
         performing BUYER'S Due Diligence.  Such investigations, studies,
         tests, information and the like shall be delivered to SELLER at no
         cost or expense to SELLER.  By furnishing BUYER'S Due Diligence
         Materials to SELLER, BUYER, to the extent such inspections, copies,
         reports or information were furnished by or obtained from third
         parties, neither warrants nor represents the accuracy of the
         information and data contained therein, nor the right of SELLER to
         rely thereon.  If BUYER terminates this Agreement in accordance with
         the provisions of Paragraph 8(c), BUYER shall return the SELLER'S Due
         Diligence Materials to SELLER.

         Upon request of BUYER at any time after the date hereof, at no expense
         to SELLER and in such a way as to not unreasonably burden or disrupt
         SELLER'S business, SELLER shall assist BUYER in its preparation of
         audited financial statements, statements of income and expense, and
         such other documentation as BUYER may reasonably request, covering the
         period of SELLER'S ownership of the Premises.

    (d)  (i)  If BUYER in its sole discretion is not satisfied with the results
              of its Due Diligence review for any reason, BUYER may terminate
              this Agreement by giving written notice (the "Termination
              Notice") of such election to SELLER, on or before the Inspection
              Period Expiration Date.  Upon termination, BUYER shall deliver to
              SELLER of all of the SELLER'S Due Diligence Materials delivered
              by SELLER or BUYER'S Due Diligence Materials received by BUYER,
              and thereafter neither party shall have any further liability or
              obligation to the other hereunder and the Deposit and all
              interest earned thereon shall be promptly returned to BUYER. 
              BUYER shall promptly return SELLER'S Due Diligence Materials
              following said termination, but it is not a condition to the
              return of BUYER'S Deposit and termination of all liabilities
              between the parties hereto.  Except as provided in Section (e) of
              this Paragraph 8, any matter existing as of the date of this
              Agreement with respect to the BUYER'S Due Diligence, including,
              without limitation, title, survey, zoning and/or governmental
              compliance matters, shall, unless BUYER terminates this Agreement
              by giving the Termination Notice, be deemed Permitted Exceptions.
              If this Agreement is not terminated as set forth in the first
              sentence of this subsection (d), all matters covered by the Due
              Diligence contingency shall be waived or deemed satisfied.  

         (ii) It shall be a condition of BUYER'S obligation to purchase the
              Premises that there be no material adverse change in any of the
              foregoing Due Diligence matters first occurring between the
              Inspection Period Expiration Date and the Closing Date.  In the
              event of any such material change pursuant to the provisions of
              Paragraph 9 hereof, unless SELLER elects to cure such material
              adverse change, BUYER'S sole right shall be to

                                       5




              terminate this Agreement in which event BUYER'S Deposit and any 
              interest thereon shall be returned.

    (e)  All rights of inspection provided for in this agreement and more
         particularly in this Paragraph 8 and the exercise of such rights shall
         not constitute a waiver by BUYER of the breach of any representation,
         warranty, covenant or agreement of SELLER which might, or should, have
         been disclosed by such inspection provided BUYER closes without being
         aware of such breach; otherwise, if BUYER discovers that breach prior
         to closing, BUYER'S sole right shall be termination of this Agreement,
         not damages.  In any and all events, any such representation,
         warranty, covenant or agreement of SELLER shall be subject to the
         limitation in paragraph 20(c).  For the purposes of this Section (e),
         BUYER shall be "aware" of such breach if Tim Jones, Dean Cingolani,
         Riccardo Cardozo or Charles Rich has actual knowledge thereof.

    9.   Extension to Perfect Title or Make Premises Conform:  If the SELLER
shall be unable to give title or to make conveyance, or to deliver possession of
the Premises, all as herein stipulated, or if at the time of the delivery of the
deed the Premises do not conform with the provisions hereof, then the SELLER
shall use reasonable efforts to remove any defects in title, or to deliver
possession free and clear of any matter relating to title or boundary survey, in
which event the SELLER shall give written notice thereof to the BUYER at or
before the time for performance hereunder, and, if SELLER elects to cure or is
required to do so pursuant to the immediately ensuing sentence, the time for
performance hereof shall be extended for a period of up to sixty (60) days as
designated in such written notice from SELLER.  The SELLER agrees to spend up to
but no more than $50,000 in using reasonable efforts, which shall include the
posting of funds to bond attachments or satisfy injunctions or court orders and
additionally SELLER agrees to discharge and pay voluntary encumbrances or liens
dischargeable by a sum certain, such as mortgages and mechanic's liens, and
created or caused voluntarily by SELLER and unpaid real estate taxes on the
Premises.  BUYER agrees that the matters listed in Exhibit B hereto shall be
deemed Permitted Exceptions.

    10.  Failure to Perfect Title or Make Premises Conform, etc.:  If at the
expiration of the extended time the SELLER shall have failed so to remove any
defects in title, deliver possession, or make the Premises conform, as the case
may be, all as herein agreed, or if at any time during the period of this
agreement or any extension thereof, the holder of a mortgage on said Premises
shall refuse to permit the insurance proceeds, if any, to be used for such
purposes, then, at the BUYER'S option, any payments made under this agreement
shall be forthwith refunded and all other obligations of all parties hereto
shall cease and this agreement shall be void without recourse to the parties
hereto.

    11.  BUYER'S Election to Accept Title:  The BUYER shall have the election,
at either the original or any extended time for performance, to accept such
title as the SELLER can deliver to the said Premises in their then condition and
to pay therefor the purchase price without deduction, in which case the SELLER
shall convey such title, except that in the event of such conveyance in
accordance with the provisions of this clause, if the said Premises shall have
been

                                       6




damaged by fire or casualty insured against, then the SELLER shall, unless
the SELLER has previously restored the Premises to their former condition,
either

    (a)  pay over or assign to the BUYER, on delivery of the deed, all amounts
         recovered or recoverable on account of such insurance plus deductible,
         less any amounts reasonably expended by the SELLER for any partial
         restoration, or

    (b)  if a holder of a mortgage on said Premises shall not permit the
         insurance proceeds or a part thereof to be used to restore the said
         Premises to their former condition or to be so paid over or assigned,
         give to the BUYER a credit against the purchase price, on delivery of
         the deed, equal to said amounts so recovered or recoverable and
         retained by the holder of the said mortgage plus deductible less any
         amounts reasonably expended by the SELLER for any partial restoration.

    Notwithstanding anything contained in this Purchase and Sale Agreement to
the contrary, in the event that the Premises are damaged by fire or other
casualty, the cost of repair of which does not exceed One Hundred Thousand
($100,000.00) Dollars, then BUYER agrees that BUYER shall not be entitled to
terminate this Agreement and notwithstanding such damage, BUYER shall accept the
Premises in their damaged condition and SELLER shall assign the insurance
proceeds to BUYER and pay over the deductible.

    12.  Acceptance of Deed:  The acceptance of a deed by the BUYER or his
nominee, as the case may be, shall be deemed to be a full performance and
discharge of every agreement and obligation of SELLER herein contained or
expressed, unless expressly stated otherwise in this Agreement.

    13.  Use of Purchase Money to Clear Title:  To enable the SELLER to make
conveyance as herein provided, the SELLER may, upon prior notice to BUYER, at
the time of delivery of the deed, use the purchase money or any portion thereof
to clear the title of any or all encumbrances or liens of which BUYER gives
SELLER timely notice, provided that all title clearing instruments are delivered
at closing with payment and in accordance with the reasonable requirements of
BUYER'S title company or consistent with customary local conveyancing practice.

    14.  Adjustments and Closing Costs:  (a) Taxes for the then current year,
prepaid rents, tenant security deposits held by SELLER, SELLER deposits held by
utility companies, water, sewer use and other municipal or quasi-governmental
charges which are for periods beyond the Closing Date, prepaid permit and
operating charges and the value of any stored fuel serving the Premises shall be
apportioned as of the day of performance of this agreement and the net amount
thereof shall be added to or deducted from, as the case may be, the purchase
price payable by the BUYER at the time of delivery of the deed.  Said
apportionments are to be done in compliance with the custom of Shelton,
Connecticut.  Uncollected rents shall be adjusted when received.  BUYER agrees
to cooperate with SELLER in SELLER'S efforts to collect past due rents and to
use reasonable efforts to attempt to collect unpaid rents due to SELLER.  SELLER
agrees not to commence legal action against any then current tenant at the
Building to collect past due rents

                                      7


without BUYER'S written approval, which shall not be unreasonably withheld or 
delayed. Payments received from tenants from and after the date of Closing 
shall be applied first to rents then due for the period current at the time 
of such receipt, and then to rents in the reverse order of delinquency (i.e. 
most recently past due rents paid first).  BUYER shall use reasonable efforts 
to collect delinquent rents for the benefit of SELLER, and shall cooperate 
with SELLER in the collection of any delinquent amounts.  BUYER shall receive 
a credit at closing against the Purchase Price in an amount equal to the sum 
of all security and other rental deposits and last month or advance rent 
payments (including interest thereon) paid by listed on Exhibit C-1.  Fees 
paid in advance under any service contracts assumed by BUYER shall also be 
prorated through the Closing Date.  The only Security Deposits held by SELLER 
as of the date of this Agreement are listed in Exhibit C-1 to this Agreement.

    SELLER shall pay all state or county documentary stamps or transfer taxes. 
BUYER shall pay all title insurance premiums and examination fees, survey costs
and the costs of its due diligence investigations, except as may specifically be
provided for herein.  Each party shall be responsible for its own attorney's
fees, and one-half (1/2) of all reasonable escrow fees and SELLER shall pay
recording fees and charges necessary or required in order for the Deed to be
recorded in the appropriate county register's or recorder's office.  SELLER
shall pay for recording of lien or encumbrance releases which SELLER is required
to deliver.  The provisions of this Paragraph 14 shall survive the Closing.

    15.  Adjustment of Unassessed and Abated Taxes:  If the amount of said
taxes is not known at the time of the delivery of the deed, said taxes shall be
apportioned on the basis of the taxes assessed for the preceding fiscal year,
with a reapportionment as soon as the new tax rate and valuation can be
ascertained; and, if the taxes which are to be apportioned shall thereafter be
reduced by abatement, the amount of such abatement, less the reasonable cost of
obtaining the same, shall be apportioned between the parties, provided that
neither party shall be obligated to institute or prosecute proceedings for an
abatement unless herein otherwise agreed.

    16.  Deposit:  All deposits made hereunder shall be held by First American
Title Insurance Company, One Financial Center, Boston, Massachusetts 02111, as
Escrow Agent (the "Escrow Agent") subject to the terms of this Agreement and
shall be duly accounted for at the time for performance of this agreement,
provided however that in the event of any disagreement between BUYER and SELLER
concerning their respective rights to the Deposit, the Escrow Agent shall retain
said deposits pending instructions mutually given by the SELLER and the BUYER or
by a court of competent jurisdiction. However, if BUYER elects to terminate this
agreement on or prior to the Inspection Period Expiration Date or if BUYER
elects to terminate this Agreement due to a material adverse change in the
condition of the Premises first occurring, between the Inspection Period
Expiration Date and the Closing as provided in Paragraph 8(d)(ii), the Escrow
Agent shall return the Deposit upon the sole instruction of the BUYER.  The
BUYER and SELLER jointly and severally agree to indemnify and hold the Escrow
Agent harmless from any and all loss, cost, damage or expense, including
attorneys' fees, arising out of its obligations as escrow agent hereunder except
for Escrow Agent's gross negligence or willful misconduct.  Escrow Agent's
conduct shall be governed by the provisions of Paragraph 40 hereof.

    17.  Default:

    (a)  BUYER'S Default; Damages:  If the BUYER shall fail to fulfill the
         BUYER'S agreements herein at closing, all deposits made hereunder by
         the BUYER shall be retained by the SELLER as liquidated damages and
         shall be SELLER'S sole remedy and damages at law and in equity. Both
         parties agree that the aforesaid amount constitutes a reasonable
         forecast of damages which would be sustained by SELLER in the event of
         BUYER's breach.

    (b)  SELLER'S Inability to Perform; Liability:  If SELLER shall be unable
         to perform SELLER'S obligations hereunder, BUYER'S sole remedy
         hereunder shall be:

         (i)  to seek Specific Performance of SELLER'S obligations hereunder;
              or 

         (ii) to cancel this Agreement and receive a return of its Deposit and
              any interest earned thereon.

    (c)  SELLER'S Failure to Perform or Default; Liability: In the event of any
         failure to perform or default on the part of SELLER hereunder (except
         as set forth in Section (d) of this Paragraph 17), or in the event
         SELLER fails to comply with any representation or warranty in this
         agreement, BUYER'S only rights and remedies shall be that BUYER shall
         be entitled to (i) terminate this Agreement upon notice to SELLER, in
         which event neither party shall thereafter have any further
         obligations under this Agreement; or (ii) to commence an action
         against SELLER seeking specific performance of SELLER'S obligations
         under this Agreement.

    (d)  SELLER'S Willful or Deliberate Failure to Perform.  In the event
         SELLER willfully or deliberately fails or refuses to perform its
         obligation to deliver title to the Premises in accordance with the
         terms of this Agreement (i.e. refuses to deliver title or voluntarily
         places a lien on the Real Property) and pursuant to "(c)" above, BUYER
         elects to terminate this Agreement rather than seek specific
         performance, SELLER shall reimburse to BUYER its actual out-of-pocket
         costs to third parties in pursuing its due diligence investigation of
         the Real Property up to an amount not to exceed Fifty Thousand
         ($50,000) Dollars based upon actual invoices evidencing such expense
         submitted to SELLER by BUYER.

    BUYER shall have no right to seek and hereby waives any right to claim
damages, consequential or otherwise, against SELLER for any breach of SELLER'S
obligations hereunder.

    18.  Liability of Trustee, Shareholder, Beneficiary, etc.:  If the SELLER
or BUYER executes this agreement in a representative or fiduciary capacity, only
the estate and entity represented shall be bound, and neither the SELLER nor
BUYER so executing, nor any employee, representative, trustee, partner, officer,
shareholder, director or beneficiary of any

                                      9


partnership, corporation or trust, nor any limited partner of any 
partnership, shall be personally liable for any obligation, express or 
implied, hereunder.

    19.  Disclaimer of Warranties and Representations:  Except for the
provisions of Paragraphs 9 and 20 hereof, the BUYER acknowledges that the BUYER
has not been influenced to enter into this transaction nor has it relied upon
any warranties or representations with respect to the condition of the Premises
or any facts or matters relating thereto.  The BUYER hereby further acknowledges
that BUYER is knowledgeable in the acquisition and ownership of commercial real
estate and that BUYER has inspected or will cause to be inspected and/or
examined to its satisfaction the Premises and all matters relating to the
ownership, title, condition (including for the presence of so-called hazardous
materials), zoning and municipal compliance, use and occupancy of and/or to the
Premises by such professionals, including, without limitation, attorneys,
engineers, surveyors and/or agents as BUYER has deemed appropriate during the
Inspection Period referred to in Paragraph 8 hereof; and that, subject only to
the "Due Diligence Contingency" contingency in Paragraph 8 of this Agreement,
which shall be deemed fully satisfied or waived unless BUYER terminates this
Agreement in accordance with the provisions of Paragraph 8, the Premises will be
conveyed to and accepted by BUYER in their "AS IS" condition without warranty or
representation other than as set forth in Paragraph 20.  BUYER acknowledges that
the SELLER has made no representations as to the condition of the Premises or
their suitability for BUYER'S purposes and that BUYER has assumed the
responsibility for this determination.  To the extent any written
correspondence, offers or other written or oral materials ("Materials") have
been exchanged between BUYER and SELLER prior to the date hereof, such Materials
shall be deemed merged into and shall be fully superseded by this Agreement and
shall be of no further force and effect.  The provisions of this Paragraph 19
shall survive the Closing.

                     relating to tenants' rights to occupy the Premises in
                     SELLER'S possession.

         (viii) All of the Service Contracts, listed on Exhibit B-1 attached

                                        11


    
      (x)     To the best of SELLER'S knowledge and belief as of the date
              hereof:  
         
              a.   except as set forth in this subsection (x)a.,(z), there are
                   no material defaults exist under the Leases, and 
              
                   (z)  Landstar has failed to pay a portion of aged previously
                        unbilled electrical usage and charges which have
                        recently been billed to them by SELLER.  Subject to the
                        other terms of this Agreement, SELLER reserves and
                        retains those arrearages and the right to collect the
                        same.
              
              b.   no condition exists, which with the passage of time or
                   giving of notice or both, will become a material default
                   under the Leases.
              
      (xi)    Except as disclosed by SELLER to BUYER as a part of the Due
              Diligence, there are no actions, suits, labor disputes,
              litigation or proceedings currently pending or, to the knowledge
              of SELLER, threatened against or related to SELLER or to all or
              any part of the Premises, the environmental condition thereof, or
              the operation thereof, nor does SELLER know of any basis for any
              such action.
              
      (xii)   There are no outstanding requirements or recommendations
              known to SELLER by (i) the insurance company(s) currently
              insuring the Premises; or (ii) any board of fire underwriters or
              other body exercising similar functions.
              
      (xiii)  SELLER has received no written notice and has no knowledge
              of (i) any pending or contemplated annexation or condemnation
              proceedings, or private purchase in lieu thereof, affecting or
              which may affect the Premises, or any part thereof, (ii) any
              proposed or pending proceeding to change or redefine the zoning
              classification of all or any part of the Premises, (iii) any
              proposed or pending special assessments affecting the Premises or
              any portion thereof, (iv) any proposed change(s) in any road or
              grades with respect to the roads providing a means of ingress and
              egress to the Premises.  SELLER agrees to furnish BUYER with a
              copy of any such notice received within two (2) business days
              after receipt.
              
      (xiv)   SELLER has provided BUYER with access at SELLER'S offices to
              all reports in SELLER'S possession and of which SELLER has
              knowledge related to the physical condition of the Premises and
              all Books and Records in SELLER'S possession and of which SELLER
              has knowledge.
              
      (xv)    SELLER has no knowledge of any notices, suits, or judgments
              relating to any violations (including environmental) of any laws,
              ordinances or regulations affecting the Premises, or any
              violations or conditions that may

                                     12



                 give rise thereto, and has no reason to believe that the 
                 Governmental Authorities contemplate the issuance thereof, 
                 and there are no outstanding orders, judgments, injunctions, 
                 decrees or writ of any Governmental Authorities against or 
                 involving SELLER or the Premises known to SELLER and which 
                 would impede SELLER'S ability to complete this Agreement.
              
         (xvi)   There are no full-time employees of the Owner working at or
                 in connection with the Premises.  There are not any union
                 agreements affecting the Premises as of the date hereof, nor
                 shall any such agreements affect the Premises as of the Closing
                 Date.
              
         (xvii)  SELLER has not made a general assignment for the benefit of
                 creditors, filed any voluntary petition in bankruptcy or to
                 SELLER'S knowledge:  (a) suffered the filing of any involuntary
                 petition by SELLER'S creditors, (b) suffered the appointment of
                 a receiver to take possession of all, or substantially all, of
                 such SELLER'S assets, (c) suffered the attachment or other 
                 judicial seizure of all, or substantially all, of such SELLER'S
                 assets, (d) admitted in writing its inability to pay its debts 
                 as they come due or made an offer of settlement, extension or 
                 composition to its creditors generally.
         
         (xviii) To the best of SELLER'S knowledge and belief, the Premises
                 are not a so-called "Establishment" as defined in the 
                 regulations of the Connecticut DEP.
         
         (xix)   To the best of SELLER'S knowledge and belief, there are no
                 so-called "Hazardous Materials" as defined under Connecticut 
                 or United States law or regulations at the Real Property in
                 violation of applicable laws or regulations.
         
         (xx)    SELLER has not received any notice that any Permits and 
                 Licenses held by SELLER pertaining to and required for the
                 ownership or operation of the Premises has been or is about
                 to be revoked or will not be renewed.
         
    (b)  For the purposes of this Paragraph 20 and the other paragraphs of this
         Purchase and Sale Agreement, "known to SELLER" or "SELLER'S knowledge"
         or similar equivalent qualifiers shall mean actual knowledge of the
         following people only:  David Mack, Jonathan G. Davis, Paul R. Marcus
         and/or David Felner.  In no event shall this description result in or
         imply any personal liability, representation or responsibility for any
         agreements, representations, obligations, liabilities or breaches of
         SELLER hereunder or elsewhere.  Where materials, documents or other
         Due Diligence materials are provided by, for or on behalf of SELLER,
         SELLER makes no representations of BUYER'S right to rely upon or the

                                      13



         accuracy or completeness of materials not prepared by SELLER even
         though furnished by, for or on behalf of SELLER.

    (c)  The foregoing representations and warranties shall be true as of the
         Closing Date and shall survive the Closing for a period of nine (9)
         months.  Except for those items which are disclosed by BUYER to SELLER
         by written notice from BUYER to SELLER within the period which ends
         nine (9) months from delivery of the deed stating specifically the
         manner in which such representation or warranty is untrue, then the
         foregoing warranties and representations shall be deemed fully
         satisfied and shall be void and without recourse to the parties
         hereto.  To the extent SELLER delivers Estoppel Certificates from
         tenants covering SELLER'S warranties and representations with respect
         to the Leases SELLER shall be relieved from such warranties and
         representations.

    (d)  BUYER hereby represents and warrants to SELLER as follows:

         (i)  BUYER is a corporation duly organized, validly existing and in
              good standing under the laws of the State of Delaware under which
              it organized and has full right, power and authority to execute
              and deliver and to perform its obligations under this Agreement;

         (ii) The execution, delivery and performance of this Agreement has
              been duly and validly authorized by all required action of BUYER

              delivered by BUYER;

         (iii) This Agreement and every document to be executed and
               delivered by BUYER pursuant to this Agreement, when fully
               executed and delivered by all intended signatories thereto, 
               shall constitute the valid and binding obligations of BUYER,
               enforceable against BUYER in accordance with their respective
               terms, subject to general equitable principals and applicable
               provisions of law related to bankruptcy, insolvency and
               creditors' rights generally.

    The foregoing representations and warranties are true as of the date hereof
and shall be true as of the Closing Date, applicable to the Closing.  

    21.  Construction of Agreement:  This instrument, executed in multiple
counterparts, is to be construed as a Connecticut contract, is to take effect as

         Agreement without the assistance of any real estate broker or person
         who would be entitled to a fee or commission in connection with this
         Agreement or the sale of the Premises by SELLER to BUYER and that
         BUYER dealt with no broker or finder with respect to his purchase of
         the Premises or this Agreement except the Brokers.  BUYER hereby
         agrees to indemnify and hold SELLER harmless from any claim by any
         broker or finder except the Brokers that a commission or fee is due to
         them as a 

                                       16



         result of having dealt with BUYER in connection with this
         Agreement or the sale of the Premises to the BUYER, or its nominee as
         may be provided herein.

    (b)  SELLER warrants and represents to BUYER that SELLER entered into this
         Agreement without the assistance of any real estate broker or person
         who would be entitled to a fee or commission in connection with this
         Agreement or the sale of the Premises by SELLER to BUYER except the
         Brokers.  SELLER hereby agrees to indemnify and hold BUYER harmless
         from any claim by any broker or finder that a commission or fee is due
         to them as a result of having dealt with SELLER in connection with
         this Agreement or the sale of the Premises to BUYER.

    (c)  Broker warrants and represents to SELLER and BUYER that Broker has not
         entered into any arrangement or agreement with any other party in
         connection with this Agreement or the sale of the Premises.  Broker
         hereby agrees to indemnify and hold SELLER and BUYER harmless from any
         claim by any broker or finder except the Brokers that a commission or
         fee is due to them as a result of having dealt with BUYER or SELLER in
         connection with this Agreement or the sale of the Premises to the
         BUYER, or its nominee as may be provided herein.

    The provisions of this Paragraph 24 will survive the Closing.

    25.  Access:  BUYER shall have the right of reasonable access to the
Premises for purposes contemplated under the Due Diligence Contingency. SELLER
shall cooperate with BUYER in facilitating its due diligence inquiry and shall
obtain, and use its best reasonable efforts to obtain, any consents that may be
necessary in order for BUYER to perform studies, tests, borings, investigations
and inspections on the Premises if permitted by SELLER.  SELLER shall also
notify BUYER of any dangerous conditions known to SELLER on the Premises,
including, without limitation, conditions which due to the nature of the
borings, studies, investigations, inspections or testing to be performed by or
on behalf of BUYER may pose a dangerous condition to BUYER or BUYER's agents and
contractors.  Notwithstanding anything herein to the contrary, in no event shall
the BUYER or any of its agents, representatives, employees, contractors or the
like ("Permitted Parties") cause any damage to the Premises which is not
promptly restored by BUYER at its sole cost and expense to as near its condition
prior to such damage or disturbance as reasonably possible, unreasonably disturb
any tenants or occupant thereat or incur any liability for SELLER.  To the
extent that any of the Permitted Parties shall in any way disturb or damage the
Premises, unreasonably disturb any tenants or occupants thereat or incur any
liability for SELLER, they shall, as a matter of due course, but in any event
upon being notified by SELLER, promptly restore the Premises at their sole cost
and expense to its condition prior to such disturbance and BUYER shall hold
SELLER harmless and indemnified from all loss, cost, damage and expense,
including reasonable attorneys' fees, as a result of any damage to the Premises
or any claim made against SELLER to the extent of any action or inaction by
BUYER or the Permitted Parties.  SELLER agrees to give BUYER prompt notice of
any claim for which SELLER is seeking indemnity and to give BUYER the right to
defend the 

                                 17



same with counsel reasonably acceptable to SELLER.  BUYER shall
notify SELLER of its intention to access the Premises at least twenty-four (24)
hours in advance of each such access and shall, if SELLER so requests, allow
SELLER or its representative to accompany BUYER or the Permitted Parties during
such access and shall reasonably accommodate SELLER by scheduling such access at
reasonable times so that SELLER can accompany BUYER or the Permitted Parties if
SELLER so wishes.  BUYER agrees to maintain appropriate property damage and
public liability insurance in amounts reasonably acceptable to SELLER and will
deliver to SELLER certificates of such insurance naming SELLER as an additional
insured prior to any access or entry onto the Premises.

    26.  Recording.  In the event this Agreement or any notice hereof shall be
recorded by BUYER, then, at SELLER'S sole option, this Agreement shall be void
and without recourse to the parties hereto.

    27.  No Binding Agreement.  This Agreement is circulated for discussion and
negotiating purposes and no agreement with respect to the purchase and sale of
the Premises shall be binding upon either of the parties hereto until this
Agreement shall have been executed by both the BUYER and the SELLER.

    28.  Insurance.  The SELLER represents that at the time of execution of
this Agreement, the SELLER maintains insurance with respect to the Premises. 
Until the delivery of the deed, the SELLER shall maintain insurance on the
improvements in the amount of One Hundred (100%) percent of their replacement
value and public liability insurance in an amount at least equal to Five Million
($5,000,000) Dollars.  The procuring of any supplemental insurance shall be at
the option and sole expense of the BUYER.

    29.  Operation and Leasing of the Premises.  SELLER agrees that between the
date of this Agreement and the date for closing and delivery of the deed, SELLER
shall operate the Premises consistently with their current operation and, except
as provided elsewhere in this Agreement, will not enter into new leases or
modify, alter or amend existing leases for the Premises without BUYER'S consent,
which shall not be unreasonably withheld or delayed.  At the closing, SELLER
shall deliver an up-to-date rent roll in the same form as Exhibit C hereto
listing all tenants, payment status of monthly rent and security deposit. SELLER
agrees and covenants not to enter into any new contracts or agreements, whether
Service Contracts or otherwise, which are not immediately cancelable by BUYER
after Closing without penalty or which are not approved by BUYER, which approval
shall not be unreasonably withheld or delayed.  SELLER also agrees that it shall
not voluntarily place any liens, encumbrances or the like against the Premises,
and if any such voluntary liens, encumbrances or the like are so placed, that
they shall be satisfied or removed of record at Closing.  It is  a condition of
BUYER's obligation to close that, except as stated in Paragraphs 35 and 44 of
this agreement, the Rent-Roll delivered at Closing shall be substantially the
same as the Rent-Roll annexed hereto as Exhibit C, or as otherwise consented to
by BUYER.

    Except for Leases or agreements approved by BUYER as contemplated above or
in Paragraph 35, SELLER also shall not: (i) enter into any agreement requiring
SELLER to do 

                                  18



work for any Tenant after the Closing Date without first obtaining
the prior written consent of BUYER;  (ii) accept the surrender of any Service
Contract or Lease, or grant any concession, rebate, allowance or free rent;
(iii) renew, extend or modify any of the Service Contracts without the prior
written consent of BUYER; (iv) remove any Personal Property located in or on the
Premises owned by SELLER and used in connection therewith, except as may be
required for repair and replacement, in which event, all replacements shall be
free and clear of liens and encumbrances and shall be of quality at least equal
to the replaced items and shall be deemed included in this sale, without cost or
expense to BUYER.  Except as stated specifically in this Agreement, SELLER may
operate the Premises and deal with tenants and contractors in the ordinary
course.  

    30.  Service Contracts and Operating Agreements.  

    (a)  All Service Contracts and other operating agreements pertaining to the
         Premises, if any, are listed on Exhibit B-1 attached hereto and made a
         part hereof.  Unless BUYER, by written notice to SELLER given at least
         twenty (20) days prior to the Closing Date, notifies SELLER in writing
         that it does not wish to assume the obligations under the operating
         agreements, then SELLER shall deliver the Premises with all operating
         agreements in place. In no event shall BUYER assume any property
         management contracts or any leasing agreement not contemplated in
         Paragraph 35 of this agreement.

    (b)  Seller will make all required payments under any mortgage affecting
         the Premises within any applicable grace period, but without
         reimbursement by BUYER therefor.  Seller shall also comply in all
         material respects with all other terms covenants, and conditions of
         any mortgage on the Premises.

    (c)  Up to and including the Closing Date, Seller agrees to maintain and
         keep such hazard, liability and casualty insurance policies in full
         force and effect in such amounts and coverage currently maintained and
         in place.

    (d)  Seller shall cancel all Service Contracts, at its sole cost and
         expense, except for those Service Contracts which BUYER elects to
         assume as provided in this Agreement.

    31.  SELLER'S Closing Documents.  On the Closing Date, in addition to any
other documents required to be delivered by SELLER under this Agreement, SELLER
shall execute and deliver or cause to be delivered to BUYER the following:

    (a)  A special warranty deed in the form of Exhibit D conveying to the
         BUYER the Premises in accordance with the terms hereof; the BUYER
         shall be entitled to nominate a third party controlled by BUYER to
         take title to the Premises provided that BUYER gives SELLER at least
         ten (10) days advance notice identifying such nominee and further
         provided that such nominee and BUYER execute and deliver to SELLER an
         assumption agreement reasonably satisfactory to SELLER by 


                                      19




         which such nominee assumes and agrees to be bound by all warranties,
         representations, obligations and liabilities of BUYER contained in
         this Agreement in which event the obligations of BUYER and such
         nominee shall be jointly and severally liable for the obligations of
         BUYER under this Agreement;

    (b)  A bill of sale in the form of Exhibit E conveying to the assignee or
         nominee of BUYER all SELLER'S right, title and interest in the
         Personal Property;

    (c)  An Assignment and Assumption Agreement Concerning Leases substantially
         in the form of Exhibit F, and which shall provide that (i) SELLER
         assigns all its rights under the Leases to BUYER and (ii) BUYER
         assumes all obligations of SELLER as landlord under the Leases;

    (d)  An Assignment and Assumption Agreement Concerning Permits and
         Licenses, and Service Contracts elected to be assumed by BUYER and
         Warranties in the form of Exhibit G;

    (e)  An affidavit of SELLER stating SELLER'S U.S. taxpayer identification
         number and that SELLER is a "United States person", as defined in
         Section 1445(f)(3) and Section 7701(b) of the Internal Revenue Code of
         1986, as amended;

    (f)  Resolutions of the board of directors of the general partner of SELLER
         certified by the Clerk thereof authorizing the execution, delivery and
         performance of this Agreement and the consummation of the transactions
         contemplated hereby, which certificate shall state that said
         resolutions are in full force and effect as of the Closing Date and
         have not been amended, modified or rescinded in any manner; 

    (g)  An incumbency certificate regarding SELLER'S corporate general partner
         issued by the Secretary of the Commonwealth of Massachusetts;

    (h)  Certificate of Legal Existence of SELLER'S corporate general partner
         issued by the Secretary of the Commonwealth of Massachusetts;

    (i)  Certificate of Legal Existence of SELLER issued by the Secretary of
         State of the Commonwealth of Massachusetts;

    (j)  Such standard title affidavits regarding parties in possession and
         indemnities regarding mechanics' liens as BUYER'S title insurer may
         reasonably require in order to delete exceptions regarding such
         matters from its title insurance coverage, including but not limited
         to standard form survey coverage, parties in possession and mechanic
         lien affidavits for any work performed at the Premises during the
         period 120 days prior to Closing required by and addressed to the
         SELLER'S title insurance company pursuant to local custom;

                                     20



    (k)  A closing and settlement statement in form and substance mutually
         satisfactory to both parties;

    (l)  A letter to each Tenant in form reasonably acceptable to BUYER
         advising it of the change in ownership of the Premises and the
         assignment of the Leases to BUYER and the transfer of its security
         deposit, if any;

    (m)  Originals, as in the possession of SELLER, of all Leases and, if any,
         Service Contracts assumed by BUYER, Promotional Materials, Permits and
         Licenses, and Books and Records owned by SELLER for the operation and
         maintenance of the Premises;

    (n)  Certificate of SELLER'S authorization to conduct business in the State
         of Connecticut, issued by the Connecticut Secretary of State;
    
    (o)  To the extent that any of the Promotional Materials, Books and
         Records, Service Contracts, and Leases known to SELLER to exist are
         not in the possession of SELLER, and SELLER shall use reasonable
         efforts, but without out-of-pocket expense, to cause the holders or
         owners of same to deliver such materials to BUYER, without cost or
         expense, which obligation shall survive the Closing;
    
    (p)  In the event BUYER determines during its Due Diligence that the
         Premises are a so-called "Establishment" subject to the Transfer Act
         under the laws of the State of Connecticut, SELLER shall, at Closing,
         sign any required documents for filing with the Connecticut DEP
         provided that no such documents shall result in any liability to the
         SELLER which SELLER does not already have, result in any expense or
         potential expense to SELLER, or obligate SELLER to take any action
         with respect to the Premises for which SELLER is not already
         responsible, and in no event shall this agreement (in this subsection
         "(p)") by SELLER or the documents to be signed by SELLER obligate
         SELLER to take any action with respect to the Premises or the
         remediation of any oils or hazardous materials thereat, BUYER'S sole
         right with respect to the discovery of so-called hazardous materials
         at the Premises during the Due Diligence shall be to timely terminate
         this Agreement and receive a return of its deposit and any interest
         thereon.  Notwithstanding the foregoing, SELLER will proceed under the
         provisions and subject to the limitations of Paragraph 9 of this
         Agreement.

    (q)  Any other document reasonably necessary to consummate the transactions
         contemplated by this Agreement, provided that such document is
         consistent with the parties' intent as expressed in this Agreement and
         does not result in any liability, warranty or representation by
         SELLER;

    (r)  On or prior to the date hereof, SELLER agrees to deliver to each
         Tenant an estoppel certificate in the form annexed hereto as Exhibit H
         for Tenant's execution, completed to reflect the Tenant's particular
         Lease status.  SELLER 

                                         21



         agrees to use its best efforts to obtain from all Tenants the estoppel
         certificates substantially in such form but reflecting the current 
         status of each Lease; provided, however, that if any Tenant shall 
         refuse to execute an estoppel letter substantially in such form, 
         SELLER shall nevertheless be obligated to use its best efforts, not 
         including judicial action or lease termination, to obtain estoppel 
         certificates in the form, if any, in which each Tenant is obligated 
         to deliver as provided in its respective Lease.  SELLER agrees to 
         deliver to BUYER, upon receipt, copies of all estoppel letters received
         by Tenants, in the form received by SELLER.  The estoppel certificates 
         required to be obtained pursuant to this Paragraph 31 are collectively
         referred to as the "Estoppel Certificates".  As a condition to BUYER'S 
         obligations to proceed with the Closing, SELLER shall deliver (i) an 
         Estoppel Certificate from each Tenant which leases space at the 
         Premises in excess of 10,000 square feet or more in the aggregate and 
         (ii) Estoppel Certificates representing in total occupancy of at least 
         seventy-five (75%) percent of the total rentable square footage of the 
         Building.  For an Estoppel Certificate to be deemed delivered for 
         purposes of this Agreement, it must certify that the Tenant's most 
         recent rental payment under its Lease was made not more than one (1) 
         month prior to the month in which the Closing occurs.  If any Tenant 
         refuses or neglects to deliver an estoppel certificate necessary to 
         comply with the foregoing, BUYER'S sole remedy under the Agreement 
         shall be to (i) terminate the Agreement and receive a refund of its 
         deposit and any interest earned thereon, or (ii) accept such Estoppel 
         Certificate, or such missing portion thereof necessary to comply with 
         the foregoing, signed by SELLER, as SELLER is willing to give, and 
         waive such non-delivery.

    32.  BUYER'S Closing Deliveries.  

    (a)  On or prior to the Closing Date, and in addition to any other document
         required to be delivered by BUYER under this Agreement, BUYER shall
         execute and deliver or cause to be delivered to SELLER, the following:

         (i)   The balance of the Purchase Price in cash, plus or minus
               adjustments contemplated herein, delivered as required under 
               this Agreement;
    
         (ii)  The Assignment and Assumption Agreements referred to herein;
    
         (iii) Such certificates as are reasonably acceptable to SELLER
               authorizing the execution, delivery and performance of this
               Agreement and the consummation of the transaction contemplated
               hereby;
    
         (iv)  A closing and settlement statement in form and substance mutually
               satisfactory to both parties;

                                      22



         (v)  Any other document reasonably necessary to consummate the
              transaction contemplated by this Agreement, provided that such
              documents are consistent with the parties' intent as expressed in
              this Agreement.
    
    (b)  The obligations of BUYER to accept title to the Premises and to
         perform the other covenants and obligations to be performed by BUYER
         on the Closing Date shall be subject to the following conditions (all
         or any of which may be waived, in whole or in part, by BUYER):  (i)
         The representations and warranties made by SELLER herein shall be true
         and correct in all material respects with the same force and effect as
         though such representations and warranties had been made on and as of
         the Closing Date;  (ii)  SELLER shall have performed all covenants and
         obligations undertaken by SELLER herein in all respects and complied
         with all conditions required by this Agreement to be performed or
         complied with by it on or before the Closing Date;  (iii)  Title to
         the Premises is such that the Title Company is able to issue to BUYER
         a Title Policy meeting the requirements set forth in Paragraph 33 for
         an "Insurable Title";  (iv)  SELLER shall have delivered to Escrow
         Agent all of the documents necessary for title transfer provided
         herein for said delivery and made arrangements reasonably satisfactory
         to BUYER for the deliver of the balance of the documents upon payment
         of the purchase price to SELLER;  (v)  There shall have been no change
         in the compliance of the Premises with all applicable environmental
         laws from that existing on the date of this Agreement.  BUYER'S
         recordation of the Deed shall be acknowledgment of full satisfaction
         of the foregoing provisions.

    (c)  The obligations of the SELLER to deliver title to and possession of
         the Premises to BUYER shall be conditioned upon payment to Escrow
         Agent of the purchase price, adjusted as contemplated herein, pending
         only continuation of title and recording of the Deed to BUYER in
         accordance with local custom.

    33.  Title Insurance. SELLER'S obligation to deliver title shall be deemed
to have been met if BUYER shall be able to obtain (which shall include SELLER'S
ability to provide), at BUYER'S sole cost and expense, from a nationally
recognized title insurance company, without additional cost above normal premium
rates, a standard form ALTA title insurance policy coverage without exception
other than the Permitted Exceptions ("Insurable Title").

    34.  Form 1099.  SELLER, through its counsel, shall be responsible for
filing Form 1099 in connection with the sale.

    35.  Leasing, Leasing Commissions and Tenant Improvements.  It shall be
SELLER'S responsibility to pay for all tenant improvements required to be
provided and/or paid for by Landlord during the currently unexpired term under
Leases currently in place.  BUYER agrees that BUYER shall assume, agree to pay
and be responsible for any and all tenant or leasehold improvements under any
new leases entered into by BUYER or entered into by SELLER with 

                                   23



the consent of BUYER and as to Leases currently in place for any and all 
options to extend, lease amendments, renewals or expansions entered or 
effective after the Closing Date.

         BUYER shall assume and agree to pay the obligations for leasing
commissions under the agreements listed in Exhibit B-2 and for any and all
leasing commissions required to be paid under Leases currently in place for
renewals, expansions, amendments and options to extend exercised or entered
after the Closing Date.

         At the Closing, SELLER shall establish a reserve fund with BUYER in
the following amounts:  (i) $78,387.38, representing an allowance of $4.125 per
square foot based upon 19,003 square feet of vacant space for leasing or rental
commissions; (ii) $380,060.00, representing an allowance of $20.00 per square
foot based upon 19,003 square feet of vacant space for tenant improvements and
build out. BUYER may use this reserve fund to pay the foregoing expenses as it
sees fit.

         The BUYER acknowledges that the foregoing is an agreed upon adjustment
between SELLER and BUYER and is neither intended to be a representation by
SELLER of actual or prospective costs and/or vacancies for the Premises or the
vacant or to become vacant space thereat.  BUYER accepts these adjustments as
fair and reasonable and agrees that BUYER shall have no right to any further
credit or adjustments for future or additional vacant space or on account of
costs for leasing or brokerage commissions or tenant improvements or build out
over and above these credits or adjustments. SELLER'S and BUYER'S obligations
under this Paragraph 35 shall survive Closing.

    36.  Confidentiality.  Prior to closing, BUYER and SELLER agree that the
terms of this transaction are confidential and that neither of them will
disclose nor permit their employees or agents to disclose the terms of this
Purchase and Sale Agreement or the transaction contemplated herein except that
SELLER may disclose the terms of this Agreement to its accountants, attorneys
and limited partners and for tax reporting purposes and BUYER may disclose the
terms of this Agreement to its prospective lenders, investors and consultants,
attorneys, accountants, and environmental consultants, who shall be placed under
the same confidentiality obligation provided there is imposed upon the same the
same agreement of confidentiality as set forth above.  Either party may disclose
such information as they may be required to disclose by any court of competent
jurisdiction or any governmental agency having authority to compel such
disclosure.   In the event of a conflict between this Paragraph 36 and the
Confidentiality Agreement previously entered into between the parties, the
Confidentiality Agreement shall control.  Notwithstanding the foregoing, BUYER
shall have the right to make such public announcements with respect to the
purchase as BUYER, as a publicly traded company, upon advice of counsel may deem
reasonably necessary or required.  BUYER agrees to give SELLER advance written
notice of such filings and announcements and to obtain SELLER'S advance written
approval which shall not be unreasonably withheld or delayed by SELLER.

    37.  Seller's Improvements.  BUYER and SELLER acknowledge that SELLER is 
currently in the process of installing a tenant directory board in the lobby 
and wallcoverings in 

                                     24



the first and second floor lobbies.  BUYER acknowledges that the directory 
board has been installed in a satisfactory manner and that the wallcoverings 
in the first floor lobby have been installed in a satisfactory manner.  
SELLER agrees to complete the wallcovering installation in the second floor 
lobby to the same level of quality as the installation of the wallcoverings 
in the first floor lobby prior to the Closing of this transaction or, at 
SELLER'S option with BUYER'S consent, not to be unreasonably withheld, to 
credit against the balance of the Purchase Price due at Closing a sum 
reasonably acceptable to BUYER to complete the installation of the 
wallcovering in the second floor lobby to the standards set forth herein, in 
which event BUYER will install the same.  BUYER acknowledges that, except as 
set forth specifically in this paragraph and in Paragraphs 29, 30 and 35 
above, as well as SELLER'S representations and warranties, SELLER shall have 
no obligations with respect to work or improvements at the Premises and that 
at Closing all such obligations shall be deemed satisfied and SELLER shall be 
released from any obligation with respect thereto.

    39.  Other Offers and Agreements.  Notwithstanding the execution and
effectiveness of this Agreement, SELLER shall have the right to solicit and
enter into "back-up" offers and/or to enter into Purchase and Sale Agreements
for the Premises whether pursuant to such "back-up" offers or otherwise provided
that any such offers and agreements contain a provision that they are expressly
contingent upon the termination of this Purchase and Sale Agreement with BUYER
and that in the event BUYER purchases the Premises from SELLER, the parties
under such back-up offers or Purchase and Sale Agreements shall have no rights
with respect to the Premises.

    40.  Escrow Agent Conduct Standards.

    (a)  The duties and obligations of the Escrow Agent shall be determined
         solely by the express provisions of this Paragraph 40 and no implied
         duties or obligations shall be implied against the Escrow Agent. 
         Further, the Escrow Agent shall be under no obligation to refer to any
         other document between or among the BUYER and the SELLER related in
         any way to this Agreement, unless Escrow Agent is provided with a copy
         of such document and consents thereto in writing.

    (b)  The Escrow Agent shall not be liable to anyone by reason of any error
         or judgment, or for any act done or step taken or omitted by the
         Escrow Agent in good faith, or for any mistake of face or law, or for
         anything which the Escrow Agent may do or refrain from doing in
         connection herewith, unless caused by or arising out of the Escrow
         Agent's actual and intentional misconduct.

    (c)  The Escrow Agent shall be entitled to rely, and shall be protected in
         acting in reliance, upon any writing furnished to the Escrow Agent by
         either the BUYER or SELLER and shall be entitled to treat as genuine,
         and as the document it purports to be, any letter, paper or other
         document furnished to the Escrow Agent in connection with its role as
         Escrow Agent.  The Escrow Agent may rely on any affidavit of either
         the BUYER or the SELLER or any other person as to the existence of any
         facts stated therein to be known by the affiant.

                                    25



    (d)  In the event of any disagreement between the BUYER and the SELLER
         resulting in adverse claims and demands being made in connection with
         or against the funds held in escrow, the Escrow Agent shall be
         entitled, at the Escrow Agent's option, to refuse to comply with the
         claims or demands of either party until such disagreement is finally
         resolved (i) by a court of competent jurisdiction (in proceedings
         which the Escrow Agent or any other party may initiate, it being
         understood and agreed by the BUYER and the SELLER that the Escrow
         Agent has authority (but no obligation) to initiate such proceedings),
         or (ii) by an arbitrator in the event that the BUYER and the SELLER
         determine to submit the dispute to arbitration pursuant to the rules
         of the American Arbitration Association, and in so doing the Escrow
         Agent shall not be or become liable to any party, or (iii) by
         unambiguous written settlement between the BUYER and the SELLER.

    (e)  The BUYER and the SELLER each agree to jointly and severally indemnify
         and hold harmless the Escrow Agent against any and all losses,
         liabilities, costs (including legal fees), and other expenses in any
         way incurred by the Escrow Agent in connection with or as a result of
         any disagreement between the BUYER and the SELLER under this Agreement
         or otherwise incurred by the Escrow Agent in any way on account of its
         role as escrow agent.

    (f)  The BUYER agrees that, in the event that a dispute arises regarding
         this Purchase and Sale Agreement and/or any actions by the Escrow
         Agent, Bernkopf, Goodman & Baseman ("BGB") may continue to represent
         the SELLER in connection with said dispute and the BUYER hereby waives
         its rights to object to said representation or any potential conflict
         as a result of BGB's role as counsel for Escrow Agent in other
         matters.

    41.  CONDEMNATION. In the event that prior to Closing, SELLER shall obtain
knowledge of the institution or threatened institution of any proceedings,
judicial, administrative or otherwise, by eminent domain or otherwise, which
propose to affect a material portion of the Premises or any portion of the
Building, SELLER shall give notice (a "Condemnation Notice") to BUYER promptly
thereafter.  Within fifteen (15) days following receipt of the Condemnation
Notice, BUYER shall have the right and option to terminate ("Condemnation
Termination Notice") this Agreement by giving SELLER written notice thereof. 
Any damage to or destruction of the entire or any portion of the Premises as a
result of a taking by eminent domain shall be deemed "material" for purposes of
this Section if the estimate of the damage, which estimate shall be a reasoned
determination performed by an insurance adjuster and BUYER's architect, shall
exceed $500,000.   Should BUYER so terminate this Agreement in accordance with
this Section, neither party shall have any further liability or obligations to
the other.  In the event BUYER shall not elect to cancel this Agreement, SELLER
shall assign all proceeds of such taking to BUYER, which assignment shall be
BUYER's sole right with respect to such taking of the Premises, and BUYER shall
have the sole right to settle any claim in connection with the Premises.  The
Closing Date shall be adjourned if the time periods set forth above so 

                                     26



require until five (5) days (or the next business day thereafter) after the 
date for the giving of the Condemnation Termination Notice.
 
    At Closing, SELLER shall execute and deliver all proper instruments as
shall be reasonably required for the conveyance to BUYER of all right, title and
interest, if any, of SELLER in and to any award or payment made, or to be made,
(i) for any taking in condemnation, eminent domain or agreement in lieu thereof
of land adjoining all or any part of the Improvements, (ii) for damage to the
Land or Improvements or any part thereof by reason of change of grade or closing
of any such street, road, highway or avenue, and (iii) for any taking in
condemnation or eminent domain of any part of the Land or Improvements.

    42.  MISCELLANEOUS PROVISIONS.      

    (a)  If any instrument or deposit is necessary, assuming SELLER is

         arrangements satisfactory to the Title Company are made in accordance
         with local custom for the timely delivery thereof subsequent to
         Closing to omit any defect, objection or exception to title, and (iii)
         Seller agrees to execute, acknowledge and deliver, to the extent
         reasonably required by the Title Company in accordance with local
         custom, any such instrument and to make any such deposit.
    
    (b)  This agreement (i) constitutes the entire agreement between the
         parties and incorporates, (ii) supersedes all prior negotiations and
         discussions between the parties, (iii) cannot be amended, waived or
         terminated orally, but only by an agreement in writing signed by the
         party to be charged, (iv) shall be interpreted and governed by the
         laws of the State of Connecticut and (v) shall be binding upon the
         parties hereto and their respective successors and assigns.
    
    (c)  The caption headings in this agreement are for convenience only and
         are not intended to be part of this agreement and shall not be
         construed to modify, explain or alter any of the terms, covenants or
         conditions herein contained.  If any term, covenant or condition of
         this Agreement is held to be invalid, illegal or unenforceable in any
         respect, this agreement shall be construed without such provision.
    
    (d)  Each party shall, from time to time, execute, acknowledge and deliver
         such further instruments, and perform such additional acts, as the
         other party may reasonably request in order to effectuate the intent
         of this agreement.  Nothing contained in this agreement shall be
         deemed to create any rights or obligations of partnership, joint
         venture or similar association between SELLER and BUYER. 

                                          27



    (e)  This agreement shall not be effective or binding until such time as it
         has been executed and delivered by all parties hereto.  This agreement
         may be executed by the parties hereto in counterparts, all of which
         together shall constitute a single agreement.
    
    (f)  All references herein to any section, schedule or exhibit shall be to
         the sections of this Agreement and to the schedules and exhibits
         annexed hereto unless the context clearly dictates otherwise.  All of

         incorporated herein.

    (g)  In the event of any litigation or alternative dispute resolution
         between SELLER and BUYER in connection with this agreement or the
         transaction contemplated herein, the non-prevailing party in such
         litigation or alternative dispute resolution shall be responsible for
         payment of all expenses and reasonable attorneys' fees incurred by the
         prevailing party.

    43.  Roof Condition:  BUYER acknowledges that it has raised certain
concerns with respect to the condition of the roof on the Building. At the
Closing, SELLER shall establish a reserve fund with BUYER in the amount of Fifty
Thousand ($50,000.00) Dollars on account of the BUYER'S concerns with the
condition of the roof. BUYER agrees that this reserve fund is in full
satisfaction of any and all obligations of SELLER with respect to existing or
future conditions with respect to the roof.  BUYER agrees that this amount is an
agreed upon maximum and full liability of SELLER in connection with the
condition of the roof and its components and is neither intended to be an
acknowledgment by SELLER of or a representation by SELLER of actual or
prospective costs for addressing conditions with respect to the roof, known or
unknown, or a sum which is to be adjusted up or down in the event the roof
conditions turn out to be less or more serious than BUYER has determined.  BUYER
agrees that SELLER has made no warranties or representations concerning the roof
or its condition and that, based upon this agreed upon reserve fund, SELLER is
released from any and all claims or liability with respect to the roof or its
condition.  BUYER may use the reserve fund as it sees fit for the purposes of
making roof repairs or replacements.

         A.   BUYER acknowledges that there are approximately 19,000 square
feet of the second floor consisting of currently vacant space and space being
vacated by Blue Cross/Blue

                                 28



Shield, the leasing of an approximately 5,000 square foot portion of which is
integral to the consummation of the transaction contemplated under this
Agreement.  SELLER has proposed to deliver the Premises at Closing to BUYER with
a lease for a 5,000 square foot portion of such space with Merlin Realty Corp.,
which lease has been executed between SELLER and Merlin Realty Corp. and has
been delivered to BUYER for its approval.  A copy of the entire lease is
attached hereto as Exhibit I.  BUYER has refused to approve the lease unless
SELLER agrees to certain conditions and SELLER has refused to agree to those
conditions unless BUYER agrees to certain conditions, all as hereinafter set
forth.  


         B.   In consideration of the BUYER'S approval of the Merlin lease,
SELLER agrees as follows:  SELLER agrees to deliver at Closing its guarantee of

tenant under the Merlin Lease. In addition, to secure its guarantee, SELLER will
at Closing post with Pryor, Cashman, Sherman & Flynn the first eighteen (18)
months' rent (the "Guarantee Security") to be paid under the Merlin lease and
BUYER may draw on the Guarantee Security to pay any monthly non-payment of rent,
which draw will cure such non-payment.  The SELLER'S guarantee shall be in the
form of Exhibit J. attached hereto.

         C.   In consideration of the SELLER accepting the conditions imposed

of the first eighteen (18) months' rent out of the Guarantee Security will be an
acceptable method of payment of rent for the first eighteen (18) months, under
the Merlin Lease.

         D.   This Paragraph 44 shall survive the Closing.
