          Seller's possession.

          3.2  CONFIDENTIAL NATURE.

               (a) Buyer agrees that all Property Documents obtained by Buyer
          from Seller during the term of this Contract with respect to the
          Property shall be held in confidence by Buyer and Buyer shall use
          reasonable efforts to ensure that such Property Documents are not
          disclosed to any third party except as provided in this subsection.
          Buyer further agrees that all information obtained by Buyer with
          respect to the Property, other than from Seller, shall be held in
          confidence and shall not be disclosed to any third party except as
          provided in this Section. All such Property Documents and other
          written materials and information shall be held in confidence and
          shall not be disclosed to any third party except (i) in connection
          only with the transactions specifically contemplated by this Contract
          (and then only to the extent necessary to accomplish the transactions
          set forth herein), to Buyer's employees, agents, lawyers, lenders,
          contractors, subcontractors, consultants and other representatives, in
          which event Buyer shall direct each such recipient of such information
          to use reasonable efforts to maintain the confidentiality of such
          information, or (ii) as required by law or court order or (iii) are
          the subject of a legitimate discovery request in any judicial
          proceeding. Notwithstanding the foregoing, Buyer shall not have any
          obligation under this subsection to maintain the confidentiality of
          any materials or information which either (a) are publicly known or
          are a matter of public record at the time such materials are made
          available to or information is disclosed to Buyer, or (b) are already
          otherwise known to Buyer at the time such materials are made available
          to or information is disclosed to Buyer, or (c) become public during
          the term of this Contract other than by means of or as a result of a
          breach of this provision by Buyer.

               (b) In the event the need arises to notify under applicable laws
          any federal, state or local public agencies of any environmental
          conditions at the Property, as a result of Buyer's Investigation, as
          described below, Buyer shall immediately notify Seller and agrees that
          Seller, not Buyer or Buyer's employees, agents, contractors,
          subcontractors, consultants or other representatives, shall make such
          disclosure as Seller deems appropriate, unless such disclosure is
          required by law to be made by Buyer or Buyer's employees, agents,
          contractors, subcontractors, consultants or other representatives, in
          which instance Buyer or such employee, agents, contractor,
          subcontractor, consultant or other representative may make such
          disclosure and Buyer shall immediately notify Seller thereof.

          3.3 RETURN OF PROPERTY DOCUMENTS. If for any reason (other than a
Seller default) the Closing does not occur, Buyer shall (i) return to Seller all
materials and other information regarding the Property that Seller has provided
to Buyer and all photocopies thereof, and (ii) upon payment of Buyer's costs in
connection therewith, deliver immediately to Seller copies of all written
studies, analysis, reports and assessments (both final and interim versions)
relating to any of Buyer's Investigations (to the extent to which such delivery
would not constitute a violation of a contract between Buyer and the consultant
which prepared such study, analysis, report or assessment). Seller acknowledges
that Buyer makes no representation or warranty as to the accuracy or
completeness of any materials delivered to Seller pursuant to clause (ii) of the
preceding sentence. For purposes of this Contract, Buyer may provide a verified
certificate to Seller certifying to its compliance with this subsection 3.3, and
such verified certificate shall be PRIMA FACIE evidence (subject to rebuttal by
Seller) of Buyer's compliance with the provisions of this subsection 3.3.

          3.4  BUYER'S INVESTIGATIONS.

               (a) Subject to the provisions of this Contract, Buyer shall, at
          its own expense, have the right to conduct or cause to be conducted
          during the period commencing on the date of this Contract and ending
          sixty (60) days thereafter ("Investigation Period"), at Buyer's sole
          cost and expense, such investigations, inspections and studies of the
          Property, including, without limitation, "Buyer's Site Assessment" (as
          hereafter defined), and such reviews of plans, contracts, permits, and
          other documents, as Buyer deems necessary or desirable (collectively,
          "Buyer's Investigations ").

               (b) All Buyer's Investigations which are permitted under this
          Contract and which require access to the Property shall be done at
          reasonable times on Business Days and after twenty-four (24) hours'
          prior written notice (which may be given by facsimile transmission) to
          R. Edward Buice, Esquire (Fax Number ((781) 246-7458) or such other
          person as is designated by Seller to Buyer from time to time
          (collectively, "Seller's Representatives"). Seller may impose
          reasonable restrictions on the timing of all Buyer's Investigations
          which required access to the Property, but such restrictions shall not
          unreasonably delay the performance of Buyer's Investigations. If
          Seller desires to have a Seller's Representative accompany Buyer, or
          its employees, agents, contractors, subcontractors, consultants or
          other representatives onto the Property during the performance of
          Buyer's Investigations. Seller shall make one or more of Seller's
          Representatives available at the Property. Buyer, its employees,
          agents, contractors, subcontractors, consultants and other
          representatives shall take all reasonable precautions to minimize the
          impact on the Property of all Buyer's Investigations. If Buyer, its
          employees, agents, contractors, subcontractors, consultants or other
          representatives take any sample from the Property in connection with
          any environmental testing as part of Buyer's Site Assessment, then
          upon Seller's request, Buyer shall provide to Seller's Representative
          a portion of such sample being tested to allow Seller, if it so
          chooses, to perform its own testing. Buyer shall, immediately after
          the conclusion of Buyer's Investigations, at its sole cost, restore
          the Property to as near the condition which existed immediately prior
          thereto as is reasonably possible, including replacing paving and
          landscaping (if any). Except as expressly stated in this Contract, in
          no event shall Buyer contact any of Seller's agents, employees,
          contractors or other representatives, (other than Seller's counsel and
          Seller's Representatives), without the prior written consent of
          Seller, not to be unreasonably withheld, delayed or conditioned.

               (c) Buyer hereby assumes all risks associated with conducting
          Buyer's Investigations and agrees to protect, defend, indemnify and
          hold harmless Seller and its officers, directors, employees and agents
          of, from and against any and all losses, claims, demands, damages,
          liabilities, expenses and other obligations (including, without
          limitation, attorneys' fees and court costs, but excluding the cost to
          remediate any Hazardous Materials discovered arising from, out of or
          in connection with or otherwise relating to, the entry by and the
          activities, studies and tests performed by Buyer or any one or more of
          its employees, agents, contractors, subcontractors, consultants or
          other representatives in or upon the Property, except as may be caused
          by the negligent or willful act or omission of Seller or its
          employees, agents, contractors, subcontractors, consultants or other
          representatives. Buyer agrees to provide Seller, and to cause each of
          its agents, contractors, subcontractors, consultants and other
          representatives who enter upon the Property to provide to Seller,
          prior to any such entry, evidence of insurance in at least the amounts
          shown on SCHEDULE 3.4(C) attached hereto and incorporated herein and
          with companies reasonably acceptable to Seller and naming Seller as an
          additional insured, covering the activities to be conducted by Buyer
          and its employees, agents, contractors, subcontractors, consultants
          and other representatives.

               (d) SURVIVAL. The foregoing restoration and indemnity obligations
          of Buyer contained in this Section shall survive the Closing or the
          termination of this Contract.

          3.5  TITLE AND SURVEY.

               (a) TITLE, EXAMINATION PRIOR TO CLOSING., WAIVER BY BUYER. During
          the Investigation Period, Buyer may, at its cost and expense, (i) have
          the title to the Property examined, (ii) have a survey made of the
          Property, and (iii) obtain a commitment ("Buyer's Commitment") for an
          owner's policy of title insurance from a nationally recognized title
          insurer (the "Title Company") at standard rates. Buyer shall give
          written notice to Seller not later than 5:00 p.m. eastern standard
          time ON THE DATE THE INVESTIGATION PERIOD EXPIRES; if Buyer's
          Commitment or Buyer's Survey discloses any title defect or
          encroachment upon the Property or other condition which is
          objectionable to Buyer (collectively, the "Title Matters"). Such
          notice of Title Matters is hereinafter referred to as a "Title
          Objection Notice". Any matter noted on Buyer's Title Commitment as of
          the effective date of Buyer's title examination, or matter in
          existence which appeared on a survey performed and prepared in
          accordance with the current ALTA/ACSM standard, which is not the
          subject of a Title Objection Notice shall be conclusively deemed
          waived by Buyer and shall constitute a "Permitted Exception".

               (b) CURING AND REMOVAL OF TITLE OBJECTIONS. If Buyer gives a
          Title Objection Notice to Seller in accordance with the provisions of
          Section 3.5(a), then:

                    (i) MONETARY ENCUMBRANCES. With respect to any Title Matter
               which is a mortgage or similar encumbrance created voluntarily by
               Seller or Seller's predecessors in title which secures solely the
               payment of a stated indebtedness (each a "Monetary Encumbrance"),
               Seller shall notify Buyer within twenty (20) days after receipt
               of such Title Objection Notice, either (i) that Seller has paid
               the amount necessary to remove the same from the record title to
               the Property and will, on or prior to the Closing Date, obtain
               recordable instruments or other documentation sufficient to cause
               the Title Company, for no additional premium, either to delete
               such matters from an owner's title insurance policy to be issued
               to Buyer at standard rates or to affirmatively insure Buyer in
               such owner's title insurance policy (in form and substance
               acceptable to Buyer) against loss arising out of the enforcement
               or attempted enforcement of such Monetary Encumbrances, or (ii)
               that Seller agrees to pay on the Closing Date the sum required to
               remove the same from the record title out of the Purchase Price
               to be received at Closing, pursuant to arrangements reasonably
               acceptable to Seller and Buyer, and will on the Closing date
               obtain recordable instruments or other documentation sufficient
               to cause the Title Company, for no additional premium, either to
               delete such matters from an owner's title insurance policy
               against loss arising out of the enforcement or attempted
               enforcement of such Monetary Encumbrances; or

                    (ii) NONMONETARY ENCUMBRANCES. If and to the extent to which
               a Title Matter both (a) is not a Monetary Encumbrance, and (b) is
               of such a nature that if it is not cured, it would prevent Seller
               from conveying a good, record and marketable title to the
               Property (such a Title Matter being hereinafter referred to as a
               "Nonmonetary Encumbrance", which term shall not include easements
               and other restrictions of record which do not interfere with the
               current use of the Property as an office and warehouse facility.
               Such easements and restrictions, although not a Nonmonetary
               Encumbrance, may nevertheless be the subject of a Title Objection
               Notice as provided in (iii) below.) Seller shall use diligent,
               good faith efforts to remove or cure all Nonmonetary
               Encumbrances, provided that:

                                    (A) Seller shall not be required to incur
                           more than $100,000 in costs and expenses (including
                           without limitation, fees and expenses of attorneys,
                           engineers and Licensed Site Professionals) in the
                           aggregate in performing the following (collectively,
                           "Seller's Cure Obligations"): (1) curing all
                           Nonmonetary Encumbrances and (2) reviewing any
                           Hazardous Materials Notice, investigating any
                           Response Action Requirement, and completing all
                           Recommended Response Actions pursuant to Section
                           3.6.2; and

                                    (B) nor shall Seller be obligated to make
                           any effort to remove or cure the same the aggregate
                           cost of Seller's Cure Obligations is reasonably
                           expected to exceed $100,000.

                  If within twenty (20) days after Seller's receipt of a Title
                  Objection Notice, Seller is not able, to remove or cure the
                  Nonmonetary Encumbrances, Seller shall so notify Buyer in
                  writing and Buyer shall, as its sole and exclusive remedy, on
                  or before the twentieth (20th) day after Buyer's receipt of
                  Seller's notice, give notice to Seller, that Buyer either:

                                    (C) PROCEED WITH CLOSING. Elects to proceed
                           with the Closing, in which event all Nonmonetary
                           Encumbrances identified in the Title Objection Notice
                           which Seller has not cured or removed shall be
                           conclusively presumed thereafter to constitute
                           Permitted Exceptions, and the Closing shall occur
                           without any credit against or abatement of the
                           Purchase Price on account thereof; or

                                    (D) TERMINATE CONTRACT. Elects to terminate
                           this Contract, in which event Buyer shall be entitled
                           to the immediate return of the Deposit, together with
                           all accrued interest thereon, and, except as
                           expressly provided, otherwise in this Contract, this
                           Contract shall be deemed terminated, null and void
                           and of no further force and effect, and the parties
                           shall have no further rights, obligations or
                           liabilities hereunder. Unless Buyer gives notice to
                           Seller within such twenty (20) day period that Buyer
                           has elected to terminate this Contract pursuant to
                           this Section (C), Buyer shall be conclusively
                           presumed to have elected to proceed to Closing
                           pursuant to Section (A), and the uncured Nonmonetary
                           Encumbrances shall be deemed waived by Buyer and
                           shall thereupon be deemed to be Permitted Exceptions.

                    (iii) OTHER OBJECTIONS. With respect to any Title Matters
               neither a Monetary Encumbrance nor a Nonmonetary Encumbrance, but
               nevertheless objectionable to Buyer, Buyer shall give Seller
               written notice thereof. Seller may, within the twenty (20) day
               period set forth in Section 3.5(b)(ii) above, either elect to
               attempt to remove such Title Matters from the record, or elect
               not to do so and notify Buyer in writing. If the Seller elects to
               do so, Seller shall use good faith, diligent efforts to do so,
               but shall not be required to expend a sum in excess of Seller's
               Cure Obligations. If Seller elects not to do so, Buyer may either
               proceed with the closing or terminate the Contract as set forth
               in Section 3.5(C) or Section 3.5(D) above by providing written
               notice to Seller within twenty (20) days from receipt of Seller's
               election notice as provided in this subsection (iii). If Seller
               fails to respond within said twenty (20) day period, Seller shall
               be deemed to have elected not to cure. If Seller fails to provide
               written notice as aforesaid, and Seller therefore elects not to
               cure, and Buyer fails to notify Seller of its election to
               terminate or proceed with the Contract, Buyer shall be deemed to
               have elected to terminate the Contract.

          If and to the extent necessary, the Closing Date shall be extended to
such period of time as necessary to give Seller and Buyer the benefit of the
time periods stated in this Section 3.5.

          Provided that Seller has complied with its obligations under this
Contract in response to a Title Objection Notice, in no event shall Buyer be
entitled to specific performance for Seller's failure to remove or cure any
Title Matter. Notwithstanding anything to the contrary contained in this
Contract, Seller shall have no obligation to cure or remove any Title Matter
which is neither a Monetary Encumbrance nor a Nonmonetary Encumbrance.

          3.6 ENVIRONMENTAL STATUS.

          3.6.1 BUYER'S SITE ASSESSMENT. Subject to the provisions of this
Contract, and in compliance with the provisions of Section 3.4 hereof, Buyer
may, during the Investigation Period, perform such due diligence ("Buyer's Site
Assessment") relating to the possible presence of oil, solid waste or hazardous
materials on the Property (including, without limitation, reviewing existing
site assessment reports and site cleanup documentation, obtaining soil and water
samples and analyzing the same, and obtaining opinions from Licensed Site
Professionals) as Buyer deems necessary to determine the condition of the
Property or the status thereof under any applicable federal, state or local law,
code, ordinance, rule, regulation, or restriction relating to oil, solid waste
or hazardous materials (collectively, "Hazardous Materials Laws"). Not later
than 5:00 p.m. eastern standard time the date the Investigation Period expires,
Buyer shall make its determination as to whether it accepts the then-current
environmental condition of the Property without requiring any further
investigation under any Hazardous Materials Laws or the issuance by any federal,
state or local governmental authority of any approval, permit, consent, license
or other determination pursuant to any Hazardous Materials Laws. If Buyer shall
request that any environmental consultant who has performed work on the Land and
Improvements provide a so-called "reliance letter" or other document in favor of
Buyer, Seller agrees to cooperate with Buyer, at no expense to Seller, to permit
Buyer to obtain such reliance letter.

          3.6.2 HAZARDOUS MATERIALS NOTICE. Buyer may give written notice to
Seller (the "Hazardous Materials Notice") not later than 5:00 p.m. eastern
standard time on the date the Investigation Period expires with respect to any
condition of the Property for which its Licensed Site Professional reasonably
believes response action is required under the Hazardous Materials Laws (each a
"Response Action Requirement"). Buyer shall include with the Hazardous Materials
Notice a copy of all reports, analyses, studies and other information (including
all boring logs and laboratory reports) to the extent in Buyer's possession,
upon which Buyer's Licensed Site Professional bases its conclusion that a
Response Action Requirement exists. Seller shall promptly review the Hazardous
Materials Notice and accompanying materials provided by Buyer and shall, if
necessary, retain a Licensed Site Professional of its choosing to review the
materials so provided by Buyer and issue a written determination (not a formal
opinion) to Seller and Buyer stating whether such Licensed Site Professional
concurs with Buyer's Licensed Site Professional that the Response Action
Requirement identified in the Hazardous Materials Notice exists (together with a
reasonably detailed statement of the basis for such conclusion), and if Buyer's
Licensed Site Professional so concurs, stating such Licensed Site Professional's
recommendations as to the measures (if any) by which to address the Response
Action Requirement in compliance with the Hazardous Materials Laws (the
"Recommended Response Actions"), together with estimates of the cost of such
Recommended Response Actions. If Buyer gives the Hazardous Materials Notice to
Seller on or before the expiration of the Investigation Period, Seller (or its
Licensed Site Professional) will respond to Buyer by ninety (90) days from the
date hereof as to whether Seller's Licensed Site Professional concurs with
Buyer's Licensed Site Professional that the Response Action Requirement
identified in the Hazardous Materials Notice exists (together with a reasonably
detailed statement of the basis for such conclusion).

          Seller shall use diligent, good faith efforts to complete the
Recommended Response Actions on or before forty-five (45) days prior to the
Closing Date, provided that:

               (a) Seller shall not be required to incur more than $100,000 in
          costs and expenses (including, without limitation, fees and expenses
          of attorneys, engineers and Licensed Site Professional) in the
          aggregate in the performance of Seller's Cure Obligations,

               (b) nor shall Seller be obligated to make any effort to undertake
          or complete any Recommended Response Actions if Seller reasonably
          determines that the aggregate cost (including, without limitation,
          fees and expenses of attorneys, engineers and Licensed Site
          Professionals) of Seller's Cure Obligations will exceed $100,000,
          unless Buyer agrees to perform this Contract notwithstanding that the
          cost to complete Seller Cure Obligations will exceed $100,000 and
          agrees affirmatively to complete any Recommended Response Action with
          reasonable diligence at its own expense.

               (c) nor shall Seller be obligated to impose any Activity and Use
          Limitation (as defined in 310 CMR 40 ET SEQ.) or other restriction on
          the use of any portion of the Property (although Seller may do so,
          with the written consent of Buyer);

          Upon completion of the Recommended Response Action, Seller's Licensed
Site Professional shall provide an opinion or certification (as is appropriate)
addressed to Seller and Buyer to the effect that the Recommended Response Action
has been completed in accordance with the requirements of applicable Hazardous
Materials Laws.

          If Seller determines that it will be unable to complete the
Recommended Response Actions by forty-five (45) days prior to the Closing Date,
Seller shall so notify Buyer in writing, and Buyer shall, as its sole and
exclusive remedy, on or before the twentieth (20) day after Buyer's receipt of
Seller's notice, give notice to Seller that Buyer either:

               (d) PROCEED WITH CLOSING. Elects to proceed with the Closing, in
          which event the Response Action Requirements identified in the
          Hazardous Materials Notice which Seller has not agreed to address
          shall be conclusively presumed thereafter to be accepted and assumed
          by Buyer and the Closing shall occur without any credit against or
          abatement of the Purchase Price on account thereof; or

               (e) EXTENSION OF CLOSING DATE. Elects to extend the Closing Date
          for a period not to exceed ninety (90) days as set forth in Buyer's
          notice to Seller, which extension shall be subject to all of the terms
          and conditions hereof, and during which extension Seller shall
          continue good faith efforts to complete the Response Action
          Requirements; or

               (f) TERMINATE CONTRACT. Elects to terminate this Contract, in
          which event Buyer shall be entitled to the immediate return of the
          entire Deposit, together with all Accrued Interest thereon, and,
          except as expressly provided otherwise in this Contract, this Contract
          shall be deemed terminated, null and void and of no further force and
          effect and the parties shall have no further rights, obligations or
          liabilities hereunder.

          Unless Buyer gives notice to Seller within such twenty (20) day period
that Buyer has elected either to extend the Closing Date pursuant to the
foregoing Section (b) or to terminate the Contract pursuant to the foregoing
Section (c), Buyer shall be conclusively presumed to have elected to proceed to
Closing pursuant to Section (d) and the Response Action Requirements set forth
in the Hazardous Materials Notice shall be deemed waived by Buyer. If Buyer
elects to extend the Closing Date pursuant to the foregoing Section (e) and the
Seller determines that it will be unable to complete the Recommended Response
Actions by the extended Closing Date. Seller shall so notify Buyer, and Buyer
shall, as its sole and exclusive remedy, on or before the twentieth (20) day
after Buyer's receipt of Seller's notice, give notice to Seller that Buyer
elects to proceed pursuant to either Section (d) or Section (f) above (and
Buyer's failure so to give such notice shall be deemed an election by Buyer to
proceed pursuant to the foregoing Section (d)).

          If and to the extent necessary, the Closing Date shall be extended for
such period of time as necessary to give Seller and Buyer the benefit of the
time periods stated in this Section 3.6.2.

          Provided that Seller has complied with its obligations under this
Contract in response to a Hazardous Materials Notice, in no event shall Buyer be
entitled to specific performance for Seller's failure to undertake or to
complete any recommended Response Actions. Notwithstanding anything to the
contrary contained in this Contract, Seller shall have no obligation to
undertake response actions, remediate or otherwise deal with any oil, solid
waste or hazardous materials which may be present upon the Property except as
specifically provided in this Section 3.6.2.

          3.7 ENGINEERING/MECHANICAL. Buyer may, within the Investigation
Period, conduct such examination of the physical, structural, mechanical,
electrical, plumbing and other components of the Building and Improvements as
Buyer deems appropriate. If Buyer is not satisfied with any aspect of this
investigation, Buyer may, by written notice to Seller given on or before the
expiration of the Investigation Period, terminate this Contract.

          3.8 BUYER'S RIGHT TO TERMINATE.

               (a) BUYER'S TERMINATION NOTICE. If the result of Buyer's
          Investigations are not satisfactory to Buyer, in its sole and absolute
          discretion, Buyer may, as its sole and exclusive remedy, terminate
          this Contract by giving to Seller written notice of Buyer's election
          to terminate ("Buyer's Termination Notice") not later than 5:00 p.m.
          eastern standard time on or before the expiration of the Investigation
          Period.

               (b) PAYMENT OF DEPOSIT UPON TERMINATION. If Buyer terminates this
          Contract pursuant to this Section 3.8, then Buyer shall be entitled to
          the immediate return of all but $5,000 of the Deposit. After Buyer
          complies with Buyer's obligations hereunder respecting the return and
          delivery of due diligence materials pursuant to Section 3.8. Buyer
          shall be entitled to immediate return of the balance of the Deposit,
          together with all Accrued interest thereon. In such event, except as
          expressly provided otherwise herein, this Contract shall be deemed
          terminated, null and void and of no further force an effect, and the
          parties shall have no further rights, obligations or liabilities
          thereunder.

               (c) WAIVER. If Buyer does not give Buyer's Termination Notice to
          Seller by 5:00 p.m. eastern standard time on or before the expiration
          of the Investigation Period, Buyer shall be conclusively presumed to
          have waived its right to terminate contained in this Section 3.8.

          Land, Improvements or any portion thereof, and Seller has not received
          any written notice, and has no knowledge, that any such proceeding is
          contemplated. The term "Seller's Knowledge" as related to this

          represents that Seller's Representatives are the persons with the most
          knowledge regarding the Property (provided, however, that Buice has
          been employed by Seller since 1995, and DeAngelis since ____________
          and have limited knowledge regarding the Property) and the
          representations and warranties made in this Contract.

               (c) Other than as disclosed in the Property Documents, there are
          no contracts of employment, management, maintenance, service, supply
          or rental outstanding which affect any portion of the Property or its
          operation that shall continue beyond Closing.

               (d) To the best of Seller's Knowledge, the continued ownership,
          operation, use and occupancy of the Land or the Improvements in the
          manner now used thereon does not violate any zoning, building, health,
          flood control, fire or other law, ordinance, order or regulation or
          any restrictive covenant. To Seller's Knowledge (but with no duty to
          conduct any independent investigation), there are no violations of any
          federal, state, county or municipal law, ordinance, order, regulation
          or requirements, affecting any portion of the Land, the Improvements

          and easements, or requesting or requiring the performance of any
          repairs, alterations or other work in order to so comply; all required
          certificates of occupancy have been duly issued and remain outstanding
          and in effect with regard to the Property.

               (f) No work has been performed or is in progress by Seller at and

          portion thereof, which might give rise to mechanic's, materialmen's or
          other liens against the Land, Improvements or Personalty or any
          portion thereof.

               (g) No part of the Property presently, or at any time in the past
          during Seller's period of ownership has been used as a dump or other
          waste disposal site. Buyer acknowledges that Seller has advised Buyer
          that the Land and Improvements have, in the past, been affected by
          Hazardous Materials and that prior owners and operators have, at
          various times, violated applicable Environmental Laws. Seller shall
          deliver Property Documents which disclose the full extent of the
          Seller's Knowledge regarding the environmental Condition of the
          Property.

               (h) Seller is not prohibited from consummating the transactions

          herein, and the individual of the Seller who executes and delivers
          this Contract and all documents to be delivered to Buyer hereunder is
          and shall be duly authorized to do so.

               (j) There are no adverse parties in possession of the Property or
          of any party thereof and no parties in possession thereof except
          Seller or the Tenant and no party has been granted any license, lease,
          or other right relating to the use or possession of the Property
          except the Tenant.

               (k) There are no attachments, executions, assignments, for the
          benefit of creditors, receiverships, conservatorships or voluntary or
          involuntary proceedings in bankruptcy or pursuant to any other debtor
          relief laws contemplated or filed by Seller or pending against Seller
          or the Property.

               (l) There are no contracts or other obligations outstanding for
          the sale, exchange or transfer of the Property or any portion thereof
          or the business operated thereon.

               (m) Seller is not a foreign person selling property as described
          in the Foreign Investment in Real Property Tax Act ("FIRPTA") and

          Property or any part thereof in any court or before any arbitrator,
          board or governmental or administrative agency or other person or
          entity which might have an adverse effect on the Property or any
          portion thereof or on Buyer's ability to operate the Property as an
          office building from and after the date hereof.

               (o) All of the bills, costs, expenses and other liabilities
          whatsoever attributable to the Property or to its ownership, operation
          or maintenance accrued or assessable to the date hereof have been paid
          in full, or if not yet due and payable, then all unpaid amounts
          accrued or assessable be paid as of the date of the Closing hereunder;
          and in the case of any, such taxes, excises and other assessments, all
          returns for periods through the date hereof have been or will be filed

          hold harmless Buyer from and against each of the matters described in

          to Buyer.

               (q) This Contract and each and every document and instrument to
          be executed and delivered by all intended signatories thereof, shall
          constitute the valid and binding obligations of Seller, enforceable

          its covenants and obligations contained in this Contract and to be
          contained in the documents and instruments to be executed and
          delivered pursuant to this Contract, and the performance of said
          covenants and obligations will not render Seller insolvent; and

               (s) Seller has not received service of process in any action,
          suit, or proceeding of any kind against or affecting Seller in any
          court of law or in equity or before or by any governmental department,
          commission, board, bureau, agency, or other instrumentality which

          Seller's actual knowledge, is any action, suit, or proceeding of any
          kind pending or threatened against or affecting Seller in any court of
          law or in equity or before or by any governmental department,

                                   ARTICLE VI

                             CONDITIONS PRECEDENT TO
                           BUYER'S OBLIGATION TO CLOSE

          6.1 CONDITIONS PRECEDENT. Buyer's obligation to consummate the
transactions contemplated hereunder is conditioned upon satisfaction of each of
the following conditions at or prior to the Closing (or such earlier date as is
specified with respect to a particular condition):

               (a) The Condition of the Property shall meet the approval of
          Buyer, in Buyer's sole judgment and discretion, upon on-site
          inspections of the Property to be made by Buyer or Buyer's
          representatives within the Investigation Period. If Buyer determines,
          in its sole and absolute discretion, that the Property does not meet
          the standards desired by Buyer, then Buyer may notify Seller of
          Buyer's decision to terminate this Contract. If canceled, the Earnest
          Money shall immediately be returned to Buyer in full and neither
          party, shall have any further obligation to the other hereunder. If
          Buyer fails to notify Seller of Buyer's disapproval prior to the
          expiration of the Investigation Period, this condition shall be deemed
          satisfied.

               (b) None of the representations and warranties of Seller set
          forth in Article V hereof shall be untrue or inaccurate in any
          material respect.

               (c) Seller shall not have failed to perform or comply with any of
          its agreements or obligations contained in this Contract in a material
          manner and within the periods provided herein.

               (d) Seller shall have delivered to Buyer Tenant Estoppel Letters
          from each of the Tenants in form substantially similar to that to be
          agreed upon by Buyer and Seller and attached hereto as EXHIBIT "C" and
          incorporated herein, or, in the alternative, Seller shall have
          indemnified Buyer as to the matters set forth in such Estoppel Letter,
          in form and substance satisfactory to Buyer.

               (e) Except as provided below, there shall have been no material
          change in the Condition of the Property between the expiration of the
          Investigation Period until the Closing:

                    (i) If the Property is damaged by fire or casualty between
               the end of the Investigation Period and the Closing Date, Seller
               shall promptly notify Buyer in writing. If (i) the cost to
               complete repairs is less than $150,000, and (ii) the damage
               occurs more than thirty days prior to the Closing Date, Seller
               shall, at the written direction of Buyer given within seven (7)
               business days of receipt of Seller's notice, either cause the
               damage to be repaired and restored to its condition immediately
               prior to such fire or casualty, or place the insurance proceeds
               plus the amount of the deductible and any other amount necessary
               to complete restorations, less reasonable expenses to clean and
               secure the site, in an escrow account to be delivered to Buyer at
               Closing. If Buyer fails to so direct Seller, Buyer shall be
               deemed to have directed Seller to restore the Property. If the
               cost to restore the Property, (iii) exceeds $150,000, or (iv)
               occurs within thirty (30) days of the Closing Date and exceeds
               $50,000 to repair/restore, Seller shall notify Buyer as aforesaid
               and Buyer may either (v) direct Seller to repair/restore, in
               which event the Closing Date shall be extended for a reasonable
               time to permit repairs to be completed, (vi) direct Seller not to
               repair but to deliver to Buyer at the Closing the insurance
               proceeds plus the applicable deductible and any other amount
               necessary to complete restorations, less reasonable expenses to
               clean and secure the site, or (vii) terminate this Contract; or

                    (ii) If any mechanical, electrical, HVAC, plumbing or
               structural component of the Building, shall fail or fall into
               disrepair between the expiration of the Investigation Period and
               the Closing Date, and the cost to repair or replace such element
               shall exceed a sum equal to $150,000 minus amounts already
               expended or to be expended by Seller with regard to Seller's Cure
               Obligations (such amount being "Seller's Capital Expense
               Obligation"), or, in the event of a change in any applicable law,
               rule or regulation affecting the Building and Improvements,
               requiring a capital expenditure in excess of Seller's Capital
               Expense Obligation, Seller shall notify Buyer of such failure and
               offer Buyer the opportunity to absorb costs and expenses in
               excess of Seller's Capital Expense Obligation. Unless Buyer
               agrees to absorb all costs in excess of Seller's Capital Expense
               Obligation associated with such replacements and improvements,
               Seller or Buyer may, by written notice to the other, terminate
               this Contract. If Buyer agrees to absorb such costs and expenses,
               Seller shall, at Buyer's discretion, either complete the required
               repairs or replacements and receive an appropriate increase in
               the Purchase Price, or not perform the improvements and reduce
               the Purchase Price by Seller's Capital Expense Obligation. In no
               event shall Seller be required to expend in excess of Seller's
               Capital Expense Obligation in the aggregate to comply with any
               changed law, rule or regulation and/or to replace any failed
               component of the Building.

In the event that all of the above conditions are not satisfied at or prior to
the Closing (or such earlier date as is specified with respect to a particular
condition), Buyer may terminate this Contract by notice to Seller and in such
event the Earnest Money shall be immediately returned to Buyer.

payment from any Tenant shall immediately upon receipt thereof pay the
appropriate amount together with written explanation of the proration
calculation. Seller shall, on or before the Closing Date, furnish to Buyer and
the Title Company all information necessary to compute the prorations provided

presently carried on at the Property. Seller may, by written notice to Buyer as
provided below ("Seller Holdover Notices") occupy the Property for up to three
(3) additional periods of thirty (30) days each (each a "Holdover Period"), not
to exceed ninety (90) days in total. To exercise Seller's rights hereunder,
Seller must provide written notice to Buyer not later than forty-five (45) days
prior to the original Closing Date or to the expiration of the first or second
thirty (30) day Holdover Term, such that Buyer receives at least forty-five (45)
days notice of each Holdover Term.

          The Holdover Terms shall, at Buyer's Option, be achieved either by a
Lease after the closing as scheduled, or by postponing the closing such that
Seller retains title to the Property during the Holdover Period(s).

          Within ten (10) days after receipt by Buyer of Seller's Holdover
Notice, Buyer shall advise Seller in writing as to whether the scheduled closing
will take place and a lease executed (the "Lease Option"), or whether the
closing shall be delayed (the "Postpone Closing Option"). If Buyer elects the
Lease Option, then Buyer and Seller agree to negotiate the Lease in good faith,
and the leased premises shall consist of the approximately 20,000 square feet of
office space and up to 10,000 square feet of the warehouse space. The Lease
shall be in form and substance reasonably acceptable to both parties, and shall
be an absolute net lease whereby Seller shall be obligated to pay 100% of all
expenses whatsoever related to or associated with the use, operation and
management of the Property during the term of the Lease and Buyer shall have no
obligation to provide any services, perform any acts or pay any expenses,
charges or costs of any kind whatsoever associated with or in any way related to
the Property. If Buyer and Seller fail to agree on the form and substance of the
Lease within ten (10) days after Buyer's election of the Lease Option, then the
parties agree that the Postpone Closing Option shall be implemented and Buyer
shall be entitled to a reduction in the purchase price as set forth herein.

          Pursuant to the Lease Option, Seller shall pay rent at the
commencement of each Holdover Term, without demand, offset, counterclaim or
deduction, as follows:

           HOLDOVER TERM                 Rent Per Month

              Month 1                       $31,000
              Month 2                       $38,000
              Month 3                       $45,000


          If Buyer elects or it shall be deemed that Buyer elects the Postpone
Closing Option, Buyer shall receive a credit against the purchase price in the
amount of the stated rent as set forth above, prorated until the Closing Date.

                                  ARTICLE VIII

                                  CONDEMNATION

          8.1 CONDEMNATION. Seller agrees to give Buyer prompt notice of any
actual or threatened taking or condemnation of all or any portion of the Land or
Improvements for which Seller obtains notice. If prior to the Closing there
shall occur the taking or condemnation of all or any portion of the Land and
Improvements, then in any such event Buyer may at its option terminate this
Contract by notice to Seller within twenty (20) days after Buyer has received
the notice referred to above or at the Closing, whichever is earlier. If Buyer
does not so elect to terminate this Contract, then the Closing shall take place
as provided herein without abatement of the purchase price, and there shall be
assigned to Buyer at the Closing all of Seller's interest in and to any
condemnation award.

                                   ARTICLE IX

                        TERMINATION, DEFAULT AND REMEDIES

          9.1 PERMITTED TERMINATION. If this Contract is terminated by either
party pursuant to a right expressly given it to do so hereunder ("Permitted
Termination"), the Earnest Money shall immediately be returned to Buyer and
neither party shall have any further rights or obligations hereunder.

          9.2 DEFAULT BY SELLER. Seller shall be in default hereunder upon the
occurrence of any one or more of the following events:

               (a) any of Seller's warranties or representations set forth
          herein are untrue or inaccurate in any material respect; or

               (b) Seller shall fail to meet, comply with or perform any
          material covenant, agreement, or obligation on its part required,
          within the time limits and in the manner required in this Contract,
          for any reason other than a Permitted Termination.

          If Seller defaults hereunder, Buyer may, at Buyer's option, do any of
the following:

                    (i) terminate this Contract by written notice delivered to
               Seller at or prior to the Closing, whereupon the Buyer's Earnest
               Money deposit shall immediately be returned to Buyer;

                    (ii) enforce specific performance of this Contract against
               Seller; or

                    (iii) seek recovery of Buyer's actual direct damages not to
               exceed the lesser of (X) $200,000, or (Y) $100,000 plus Buyer's
               direct out of pocket expenses for engineers, lawyer's
               consultants, commitment fees and all other actual third party
               expenses associated with or related to the transactions
               contemplated by this Contract.

          9.3 DEFAULT BY BUYER. Buyer shall be in default hereunder if any of
Buyer's warranties or representations set forth herein are untrue or inaccurate
in any material respect. If Buyer defaults hereunder, Seller, at Seller's sole
and exclusive remedy for such default, shall be entitled to terminate this
Contract by notice to Buyer within ten (10) days after discovery of such default
and retain Buyer's Earnest Money, it being agreed between Buyer and Seller that
such sum shall be liquidated damages for a default of Buyer hereunder because of
the difficulty, inconvenience, and the uncertainty of ascertaining actual
damages for such default.

          9.4 ATTORNEY'S FEES. If it shall be necessary for either Buyer or
Seller to employ an attorney to enforce its rights pursuant to this Contact
because of the default of the other party, the defaulting party shall reimburse
the non-defaulting party for reasonable attorney's fees.

                                    ARTICLE X

               (d) Seller will enter into no agreement with respect to the

complete and final expression of the agreement of the parties relating to the
Property, and supersedes all previous contracts, agreements, and understandings
of the parties, either oral or written, relating to the Property. This Contract

in writing (referring specifically to this Contract) executed by the party
against whom enforcement of the modification or waiver is sought.

          12.6 COUNTERPART EXECUTION. This Contract may be executed in several

time period shall be extended so that it shall end on the next succeeding day
which is not a Saturday, Sunday or legal holiday.

(including attorneys' fees) as a result of any action, suit, proceeding or claim
affecting the Land, Improvements or Personalty or any portion thereof, or any
contracts and/or services related thereto, in relation to which the facts which
give rise to such action, suits or proceedings arose or occurred prior to the
Closing Date, including but not limited to claims brought pursuant to Sections
10.1(d) and (e). Buyer agrees to indemnity and hold Seller harmless of and from
any and all liability, loss, damage or expense (including attorneys' fees) as a
result of any action, suite, proceeding or claim affecting the Land,
Improvements, Personalty or any portion thereof, or any contracts and/or
