     2.4  Objection Notice. If Buyer is not satisfied in its sole discretion
with any of its inspections, reviews or with any other matter concerning the
Property, Buyer may, on or prior to the expiration of the Due Diligence Period,
either (i) terminate this Agreement by notice to Seller, in which event the
Earnest Money shall be immediately returned to Buyer and neither party shall
have further obligations hereunder, except as specifically set forth herein or
(ii) accept the Property by providing written notice to Seller of such
acceptance or (iii) raise certain objections by providing notice in writing (the
"Objection Notice"), which Objection Notice may, at Buyer's option, specify
which matters (the "Objections") Buyer does not find satisfactory with respect
to the Property. If Buyer does not timely provide an Objection Notice or an
acceptance notice, Buyer shall be deemed to have terminated this Agreement as
provided above.

     If Buyer timely provides an Objection Notice, Seller shall have ten (10)
days after delivery of such Objection Notice to remove or cause to be corrected
to Buyer's satisfaction, all of such Objections. In all cases, Seller shall be
obligated at Closing to fully discharge all liens of a definite and
ascertainable amount that are not specifically assumed or accepted by Buyer in
writing as well as those exceptions or encumbrances to title which arise after
the date of the Title Commitment. If the aggregate amount of such liens or
encumbrances exceeds the Purchase Price for the Property (plus or minus
prorations), Seller shall, during such ten (10) day period, provide evidence
reasonably satisfactory to Buyer of Seller's financial ability to fully
discharge such excess amounts.

     If Seller fails or refuses to cause the Objections to be removed and
corrected to Buyer's satisfaction within such ten (10) day period, or fail to
present evidence of its financial ability to satisfy such excess liens by such
date, then Buyer shall elect, on or prior to the date and time that is twenty
(20) days after the delivery of the Objection Notice, at 5:00 p.m., Boston time,
to (i) terminate this Agreement, in which event the Earnest Money shall be
immediately returned to Buyer and neither party shall have any further
obligations hereunder, except as specifically set forth herein or (ii) accept
the Property subject to any Objections and proceed to close, with the further
right to deduct from the Purchase Price amounts secured by liens of a definite
or ascertainable amount which Seller has not removed as provided herein as well
as amounts required to remove any exceptions or encumbrances which arise after
the date of the Title Commitment. If Buyer makes no such election, Buyer shall
be deemed to have elected to terminate this Agreement as provided above.

     If after the expiration of the Due Diligence Period, the Title Company
revises the Title Commitment or the surveyor revises the Survey to add or modify
exceptions, or to add or modify the conditions to obtain any of the
Endorsements, then, unless Buyer elects by notice to Seller to accept such
exceptions or conditions within ten (10) days after being notified thereof, then
this Agreement shall be deemed terminated as provided above. If, within such ten
(10) day period, Buyer notifies Seller that it objects to such new matters (the
"Post-Commitment Objection Notice") then Seller will have ten (10) days after
delivery of such Post-Commitment Objection Notice to remove or cause to be
corrected to Buyer's satisfaction, all of such new matters. If Seller fails or
refuses to cause such new matters to be removed or corrected to Buyer's
satisfaction within such ten (10) day period, then Buyer shall elect, on or
prior to the date and time that is twenty (20) days after the delivery of the
Post-Commitment Objection Notice, at 5:00 p.m., Boston time, to (i) terminate
this Agreement or (ii) accept the Property subject to such new

                                      -6-

<PAGE>

matters and proceed to close, with the further right to deduct from the Purchase
Price amounts secured by liens of a definite or ascertainable amount which
Seller has not removed as provided herein as well as amounts required to remove
such new matters. If Buyer makes no such election, Buyer shall be deemed to have
elected to terminate this Agreement as provided above.

     If necessary, the Closing Date shall be extended the number of days
necessary to give effect to the notice and cure periods set forth in this
Section 2.4.

     2.5  Service Contracts. During the Due Diligence Period, Buyer shall notify
Seller as to which Service Contracts Buyer will assume (the "Accepted Service
Contracts"). Buyer will assume the obligations arising from and after the
Closing Date under the Accepted Service Contracts that are not in default as of
the Closing Date. Seller shall terminate at Closing all Service Contracts that
are not so assumed and if Buyer fails to timely provide notice of acceptance,
Buyer shall be deemed to not have assumed any Service Contracts.

     2.6  Intentionally Omitted.

     2.7  Intentionally Omitted.

     2.8  CCRs. If the Property is subject to a declaration of covenants,
conditions and restrictions or similar instrument ("CCRs") governing or
affecting the use, operation, maintenance, management or improvement of such
Property, then as a condition to Buyer's obligation to close, at Closing, Seller
shall deliver into the escrow: (i) estoppel certificates, in form and substance
satisfactory to Buyer, from the declarant, association, committee, agent and/or
other person or entity having governing or approval rights under the CCRs, and
(ii) a recordable assignment, in form and substance satisfactory to Buyer,
assigning any and all developer, declarant or other related rights or interests
of Seller (or any Affiliate of Seller) in or under the CCRs.

in Appendix 2.9 constitute a complete list of all of the Loan Documents and have
not been amended or modified except as set forth on Appendix 2.9. Seller has not
received any notice that Seller is in default under the Loan Documents, nor does
any default or breach exist beyond any applicable cure period nor, to Seller's
knowledge, does any default or breach exist, or any event or circumstance,
which, with the giving of notice or passage of time, or both, would constitute a
default or breach by Seller under the Loan Documents.

     6.2 Buyer's Representations and Warranties. As a material inducement to
Seller to execute this Agreement and consummate this transaction, Buyer
represents and warrants to Seller that:

(a)  Organization and Authority. Buyer has been duly organized and is validly
existing as a Delaware corporation. Subject only to obtaining certain Board and
other internal approvals on or before the expiration of the Due Diligence
Period, Buyer has the full right and authority and has obtained any and all
consents required to enter into this Agreement and to consummate or cause to be
consummated the transactions contemplated hereby. This Agreement has been, and
all of the documents to be delivered by Buyer at the Closing will be, authorized
and properly executed and constitutes, or will constitute, as appropriate, the
valid and binding obligation of Buyer, enforceable in accordance with their
terms.

(b)  Conflicts and Pending Action. There is no agreement to which Buyer is a
party or to Buyer's knowledge binding on Buyer which is in conflict with this
Agreement. There is no action or proceeding pending or, to Buyer's knowledge,
threatened against Buyer which challenges or impairs Buyer's ability to execute
or perform its obligations under this Agreement.

(c)  Tenant of the Property. Varian Semiconductor Equipment Associates, Inc. is
the tenant of the Property under the Lease and is in possession of the entire
Property pursuant to the Lease. Varian Semiconductor Equipment Associates, Inc.
has not sublet any portion of the Property.

     6.3 Survival of Representations and Warranties. The representations and
warranties set forth in this Article 6 are made as of the date of this Agreement
and each of Seller

                                      -19-

<PAGE>

and Buyer shall be deemed to have remade all of their respective representations
and warranties as of the Closing Date. Such representations and warranties and
shall not be deemed to be merged into or waived by the instruments of Closing,
but shall survive the Closing for a period of two (2) years. Seller and Buyer
shall have the right to bring an action for breach of such representations and
warranties if they give the other party written notice of the circumstances
giving rise to the alleged breach within such two (2) year period and have
brought an action thereon within six (6) months of the expiration of such
period.

                        ARTICLE 7: DEFAULT AND REMEDIES

     7.1 Seller's Default. If this transaction fails to close as a result of
Seller's default (all conditions to Seller's obligations having been satisfied
or waived), the Earnest Money shall be returned to Buyer. In addition, Buyer
shall be entitled to such remedies for breach of contract as may be available at
law and in equity, including without limitation, the remedy of specific
performance. If, after Seller's default, Buyer elects not to proceed with the
Closing, then Seller will, on demand, reimburse Buyer for all expenses incurred
by Buyer in connection with this Agreement, including all due diligence
expenses.

     7.2 Buyer's Default. If this transaction fails to close due to the default
of Buyer (all conditions to Buyer's obligations having been satisfied or
waived), then Seller's sole remedy in such event shall be to terminate this
Agreement and to retain the Earnest Money as liquidated damages, Seller waiving
all other rights or remedies in the event of such default by Buyer. The parties
acknowledge that Seller's actual damages in the event of a default by Buyer
under this Agreement will be difficult to ascertain, and that such liquidated
damages represent the parties' best estimate of such damages.

     7.3 Other Expenses. If this Agreement is terminated due to the default of a
party, then the defaulting party shall pay any fees due to the Escrow Agent for
holding the Earnest Money and any fees due to the Title Company for cancellation
of the Title Commitment.

                           ARTICLE 8: INDEMNIFICATION

     8.1 Seller's Indemnity. Seller shall indemnify, defend and hold Buyer
harmless from any liability, claim, demand, loss, expense or damage
(collectively, "loss") that is: (a) suffered by, or asserted by any person or
entity against Buyer arising from any act or omission of Seller, its agents,
employees or contractors or otherwise arising out of the ownership or operation
of the Property first arising or occurring prior to the Closing; or (b) arising
out of the breach or inaccuracy of any of Seller's representations and
warranties set forth herein or (c) arising from any breach by Seller of any
obligation related to the Property other than those obligations which by this
Agreement, or any closing delivery, specifically becomes the obligation of
Buyer.

     8.2 Buyer's Indemnity. Buyer shall indemnify, defend and hold Seller
harmless of and from any loss that is: (a) suffered by, or asserted by any
person or entity against, Seller arising from any act or omission of Buyer, its
agents, employees or contractors or otherwise arising out of the ownership or
operation of the Property first arising or occurring on or after the Closing; or
(b) arising out of the breach or inaccuracy of any of Buyer's representations or

                                      -20-

<PAGE>

warranties set forth herein or (c) arising from any breach by Buyer of any
obligation of Buyer related to the Property which by this Agreement, or any
closing delivery, specifically becomes the obligation of Buyer.

     8.3 Procedure. The following provisions govern all actions for indemnity
under this Article 8 and any other provision of this Agreement. Promptly after
receipt by an indemnitee of notice of any claim, such indemnitee will, if a
claim in respect thereof is to be made against the indemnitor, deliver to the
indemnitor written notice thereof and the indemnitor shall have the right to
participate in and, if the indemnitor agrees in writing that it will be
responsible for any costs, expenses, judgments, damages, and losses incurred by
the indemnitee with respect to such claim, to assume the defense thereof, with
counsel mutually satisfactory to the parties; provided, however, that an
indemnitee shall have the right to retain its own counsel, with the fees and
expenses to be paid by the indemnitee, if the indemnitee reasonably believes
that representation of such indemnitee by the counsel retained by the indemnitor
would be inappropriate due to actual or potential differing interests between
such indemnitee and any other party represented by such counsel in such
proceeding. The failure of indemnitee to deliver written notice to the
indemnitor within a reasonable time after indemnitee receives notice of any such
claim shall relieve such indemnitor of any liability to the indemnitee under
this indemnity only if and to the extent that such failure is prejudicial to the
indemnitor's ability to defend such action, and the omission so to deliver
written notice to the indemnitor will not relieve it of any liability that it
may have to any indemnitee other than under this indemnity. If an indemnitee
settles a claim without the prior written consent of the indemnitor, then the
indemnitor shall be released from liability with respect to such claim unless
the indemnitor has unreasonably withheld such consent.

     8.4 Survivability. The obligations of the parties under this Article 8
shall survive the Closing.

                            ARTICLE 9: MISCELLANEOUS

     9.1 Parties Bound. Neither party may assign this Agreement without the
prior written consent of the other, and any such prohibited assignment shall be
void; provided, however, that Buyer may assign this Agreement without Seller's
consent to an Affiliate. Buyer shall not be relieved of its obligations under
this Agreement in the event of such assignment. Subject to the foregoing, this
Agreement shall be binding upon and inure to the benefit of the respective legal
representatives, successors, assigns, heirs, and devises of the parties.

     9.2 Headings. The article and paragraph headings of this Agreement are for
convenience only and in no way limit or enlarge the scope or meaning of the
language hereof.

     9.3 Invalidity and Waiver. If any portion of this Agreement is held invalid
or inoperative, then so far as is reasonable and possible the remainder of this
Agreement shall be deemed valid and operative, and, to the greatest extent
legally possible, effect shall be given to the intent manifested by the portion
held invalid or inoperative. The failure by either party to enforce against the
other any term or provision of this Agreement shall not be deemed to be a waiver
of such party's right to enforce against the other party the same or any other
such term or provision in the future.

                                      -21-

     9.5  Survival. The provisions of this Agreement that contemplate
performance after the Closing, the obligations of the parties not fully
performed at the Closing, and all indemnities set forth in this Agreement shall
survive the Closing and shall not be deemed to be merged into or waived by the
instruments of Closing.

     9.6  No Third Party Beneficiary. This Agreement is not intended to give or
confer any benefits, rights, privileges, claims, actions, or remedies to any
person or entity as a third party beneficiary, decree, or otherwise.

an instrument in writing executed by the party against whom enforcement is
sought.

     9.8  Time. Time is of the essence in the performance of this Agreement.

     9.9  Confidentiality. Seller shall make no public announcement or other
disclosure of this Agreement or any information related to this Agreement to
outside brokers or third parties, before or after the Closing, without the prior
written specific consent of Buyer; provided, however, that Seller may make
disclosure of this Agreement to its lenders, creditors, officers, employees and
agents as necessary to perform its obligations hereunder.

     9.10 Enforcement Expenses. Should either party employ attorneys to enforce
any of the provisions hereof, the party against whom any final judgment is
entered agrees to pay the prevailing party all reasonable costs, charges, and
expenses, including attorneys' fees and costs, expended or incurred in
connection therewith.

     9.11 Notices. All notices required or permitted hereunder shall be in

using a nationally recognized overnight courier, in which case notice shall be
deemed delivered one business day after deposit with such courier, (b) sent by
certified or regular U.S. mail, postage prepaid, in which case notice shall be
deemed delivered two business days after deposit in such mails, (c) sent by
facsimile, in which case notice shall be deemed delivered upon the mechanical
confirmation of delivery, or (d) sent by personal delivery, in which case notice
shall be deemed delivered upon receipt or refusal of delivery. A party's address
may be changed by written notice to the other party; provided, however, that no
notice of a change of address shall be effective until actual receipt of such
notice. Copies of notices are for informational purposes only, and a failure to
give or receive copies of any notice shall not be deemed a failure to give
notice. Notices given by counsel to Buyer shall be deemed given by Buyer and
notices given by counsel to Seller shall be deemed given by Seller.

     9.12 Construction. The parties acknowledge that the parties and their
counsel have reviewed and revised this Agreement and the documents to be
executed at the Closing and agree

                                      -22-

<PAGE>

     9.17 Further Assurances. In addition to the acts and deeds recited herein
and contemplated to be performed, executed and/or delivered by either party at

obligation to incur any additional liability or expense, on or after the Closing

conveyance, transfer and assignment of the Property to Buyer.

     9.18 Waiver of Jury Trial. TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE

     9.20 1031 Exchange. Buyer may consummate the purchase of the Property as
part of a so-called like kind exchange (the "Buyer's Exchange") pursuant to
Section 1031 of the Code, provided that: (1) the Closing shall not be delayed or
affected by reason of the Buyer's Exchange nor shall the consummation or
accomplishment of the Buyer's Exchange be a condition precedent or condition
subsequent to Buyer's obligations under this Agreement; (2) Buyer shall effect
the Buyer's Exchange through an assignment of this Agreement, or its rights
under this Agreement, to a qualified intermediary; (3) Seller shall not be

                       Legal Description of Real Property

     That certain real property located at 4 Stanley Tucker Drive, Newburyport,
MA, and more particularly described as follows:

     A certain parcel of land in Newburyport, Massachusetts, being shown as lot
62 on a plan entitled "Site Survey Plan of Land in Newburyport, Massachusetts",
prepared by Port Engineering Associates, Inc., dated October 27, 1995," which
plan is recorded with the deed at Book 13275, Page 483.

                                  APPENDIX 1.3

                                Escrow Agreement

     This Escrow Agreement (this "Agreement") is made as of the ___ day of
________________________, 2002 by and among Berkshire-Newburyport Limited
Partnership ("Seller"), Varian Semiconductor Equipment Associates, Inc.
("Buyer") and First American Title Insurance Company ("Escrow Agent").

                                 R E C I T A L S

     A. Seller and Buyer have entered into that certain Purchase and Sale
Agreement (the "Purchase and Sale Agreement") dated as of even date herewith,
with respect to certain property (the "Property") described therein.

     B. All terms capitalized but not defined herein, shall have the respective
meanings ascribed to them in the Purchase and Sale Agreement.

     C. Pursuant to the Purchase and Sale Agreement, among other things, Buyer
has and will make deposits of Earnest Money to be held, invested and disbursed
as provided herein.

     NOW, THEREFORE, for good and valuable consideration the receipt and
sufficiency of which are hereby acknowledged the parties hereto agree as
follows:

     1. Recitals. The recitals set forth above are true and correct and are
incorporated herein by reference.

     2. Investment and Use of Funds. The Escrow Agent shall invest the Earnest
Money in investments directed by Buyer, shall not commingle the Earnest Money
with any funds of the Escrow Agent or others except as provided herein, and
shall promptly provide Buyer and Seller with confirmation of the investments
made.

     3. Termination before Expiration of Due Diligence Period. Buyer shall
notify the Escrow Agent of the date that the Due Diligence Period ends promptly
after such date is established under the Purchase and Sale Agreement, and Escrow
Agent may rely upon such notice. If Buyer elects (or is deemed to have elected)
to terminate the Purchase and Sale Agreement on or prior to the expiration of
the Due Diligence Period, Escrow Agent shall, upon written direction from Buyer,
pay the entire Earnest Money to Buyer one business day following receipt of such
direction (as long as the current investment can be liquidated in one day),
despite any contrary instructions from Seller. Seller agrees it shall have no
right to bring any action against Escrow Agent which would have the effect of
delaying, preventing, or in any way interrupting Escrow Agent's delivery of the
Earnest Money to Buyer pursuant to this paragraph, any remedy of Seller being
against Buyer, not Escrow Agent.

     4. Termination after Expiration of Due Diligence Period. At any time after
the expiration of the Due Diligence Period, Escrow Agent shall retain the
Earnest Money until it receives written instructions executed by both Seller and
Buyer as to the disposition and disbursement of the Earnest Money, or until
ordered by final court order, decree or judgment,

<PAGE>

which is not subject to appeal, to deliver the Earnest Money to a particular
party, in which event the Earnest Money shall be delivered in accordance with
such notice, instruction, order, decree or judgment.

     5. Interpleader. Seller and Buyer mutually agree that in the event of any
controversy regarding the Earnest Money after the expiration of the Due
Diligence Period, unless mutual written instructions are received by the Escrow
Agent directing the Earnest Money's disposition, the Escrow Agent shall not take
any action, but instead shall await the disposition of any proceeding relating
to the Earnest Money or, at the Escrow Agent's option, the Escrow Agent may
interplead all parties and deposit the Earnest Money with a court of competent
jurisdiction in which event the Escrow Agent may recover all of its court costs
and reasonable attorneys' fees. Seller or Buyer, whichever loses in any such
interpleader action, shall be solely obligated to pay such costs and fees of the
Escrow Agent, as well as the reasonable attorneys' fees of the prevailing party
in accordance with the other provisions of the Purchase and Sale Agreement.

     6. Liability of Escrow Agent. The parties acknowledge that the Escrow Agent
is acting solely as a stakeholder at their request and for their convenience,
that the Escrow Agent shall not be deemed to be the agent of either of the
parties, and that the Escrow Agent shall not be liable to either of the parties
for any action or omission on its part taken or made in good faith, and not in
disregard of this Agreement, but shall be liable for its willful misconduct and
negligent acts and for any loss, cost or expense incurred by Seller or Buyer
resulting from the Escrow Agent's mistake of law respecting the Escrow Agent's
scope or nature of its duties. Seller and Buyer shall jointly and severally
indemnify and hold the Escrow Agent harmless from and against all costs, claims
and expenses, including reasonable attorneys' fees, incurred in connection with
the performance of the Escrow Agent's duties hereunder, except with respect to
actions or omissions taken or made by the Escrow Agent in bad faith, in
disregard of this Agreement or involving willful misconduct or negligence on the
part of the Escrow Agent. In the event the Escrow Agent is directed to invest
the Earnest Money, the Escrow Agent shall not be held responsible for any loss
of principal or interest which may be incurred as a result of making the
directed investments or redeeming said investments at the direction of the
parties hereto.

     7. Commingling. The Escrow Agent may commingle the Earnest Money with other
deposits or with its own funds in the manner provided for the administration of
funds pursuant to applicable law; provided, however, that nothing herein shall
diminish the Escrow Agent's obligation to apply the full amount of the Earnest
Money in accordance with the terms of this Agreement.

     8. Closing. At Closing, the Escrow Agent shall fund the Earnest Money into
the closing escrow, to be delivered to Seller and applied as a credit against
the Purchase Price.

     9. Execution in Counterparts. This Agreement may be executed in any number
of counterparts, each of which shall be deemed to be an original, and all of
such counterparts shall constitute one Agreement. To facilitate execution of
this Agreement, the parties may execute and exchange by telephone facsimile
counterparts of the signature pages.
