materially limit CuraGen from utilizing or developing the Property;

     (g) to Beauvais' actual knowledge, there is no material violation of any

     (b) Wetland map or data in his possession;
     (c) A List of all Leases and the terms thereof;
     (d) Copies of all Leases

     The Purchaser shall expedituously perform all due diligence with respect to

contract the Purchaser determines to cancel and terminate this contract, he
shall then receive a refund of the aforesaid deposit upon delivery to Nevas,
Nevas, Capasse & Gerard, 246 Post Road East, P.O. Box 791, Westport, Connecticut

expiration of said thirty (30) days after the decision of the Purchaser not to
terminate all sums paid hereunder shall be non-refundable.

     The Purchaser shall have one hundred eighty (180) days to obtain necessary
Branford Planning and Zoning Permits and Branford Wetlands Commission Permits
providing, however, that the Purchaser shall have diligently pursued such
applications and has filed said applications within sixty (60) days of the
execution of the contract.

     If the Purchaser diligently pursues such applications but there has not
been favorable action by the Planning and Zoning Commission and the Wetlands
Commission within said nine (9) month period, the Purchaser may, at his option,
extend the time for obtaining such permits for an additional



                                       -2-

<PAGE>

period of thirty (30) days upon payment of TWENTY-FIVE THOUSAND and 00/100
($25,000.00) DOLLARS. If, within the said thirty (30) days, the Purchaser
desires to extend the closing date for an additional thirty (30) days because of
the failure to obtain said permits, the Seller agrees that upon the payment of
an additional sum of TWENTY -FIVE THOUSAND and 00/100 ($25,000.00) DOLLARS the
closing date shall be extended for an additional thirty (30) days. The said
payments of FIFTY THOUSAND and 00/100 ($50,000.00) DOLLARS shall not be
refundable and shall not be credited on account of the purchase price.

5. Bond/Security Deposit.
   -----------------------

     The Seller has deposited with the Town of Branford a security deposit in
the amount of FIFTY EIGHT THOUSAND and 00/100 ($58,000.00) DOLLARS, which sum
shall be reimbursed by the Purchaser to the Seller at the time of closing. The
Seller shall assign to the Purchaser all rights and claims to the said bond.
Seller shall provide the Buyer with a copy of the bond and all supporting
documentation within ten (10) days of the date of the contract.

6. Adjustments, Prepaid Rents, Tax Reduction Proceedings.
   -------------------------------------------------------

     (a). The following items shall be adjusted between Seller and Purchaser as
of 12:01 a.m. of the Closing Date:

          (i). Real Estate, Personal Property and Other Municipally or State
               --------------------------------------------------------------
               Imposed Taxes.
               --------------
          Current real estate, personal property and other taxes, if any, which
are, or may become liens on the Property for the year of the closing shall be
assumed by Purchaser. Such taxes shall be adjusted pursuant to the custom
adopted by the Assessor of the Town of Branford and Guilford. If the assessment
or the tax rate shall not have been set as of the Closing Date, taxes shall be
assumed on the basis of the most recently ascertainable tax bill. When such
assessment or tax rate for the period covered by the assumption shall become
available, the Purchaser agrees to assume the increase in taxes associated
therewith, if any.

          (ii). Rents. The total rent potential for the calendar month during
which the closing shall take place, as set forth on the Leases delivered to
Purchaser at the closing whether or not all of such rents shall have been
received by Seller as of the Closing Date. All rental income attributable to a
period of time prior to the closing shall be payable to Seller and all rents
earned and attributable to any period after the closing shall be paid to
Purchaser. Seller specifically reserves the right to retain and/or proceed with
any and all claims for rentals attributable to its period of ownership. Any
payments received by Purchaser after closing, less any expenses of collection
incurred by Purchaser including reasonable attorney's fees, shall first be
applied to current rents due and the balance paid to Seller on account of any
rental arrearage shown on the Schedule of Leases attached hereto. Purchaser
shall not be obligated to bring suit to collect such arrearages. Rents prepaid
by tenants for any month subsequent to the month during which the closing shall
occur shall be credited to Purchaser by the Seller at the closing, or, if
received by Seller after the closing, shall be promptly remitted to Purchaser.



                                       -3-

<PAGE>

         (iii). Service and Other Contracts. Amounts, if any, prepaid or
                ----------------------------
accrued by Seller with respect to any service or other contracts assigned or
transferred to Purchaser at the closing, shall be credited to the Seller at the
time of the closing.

         (iv). Utilities. If any utility bills are presently in the name
               ----------
of the Seller, Seller shall use its best efforts to have utility meters read as
of the Closing Date and to cause utility companies to render final bills to
Seller, which bills Seller shall pay promptly. If a final bill shall not have
been rendered as of the Closing Date, the prepaid or unbilled, as the case may
be, amount of such utility shall be prorated on the basis of the most recently
ascertainable bill for such utility, and such utility shall be adjusted, if
necessary, when the actual bill therefore for the period covered by the
proration shall become available, and the appropriate credit or payment shall be
made between Seller and Purchaser upon demand of either party. For the purposes
of this paragraph "utilities" shall include but shall not be limited to
electricity, natural gas and fuel oil.

          (v). Water Hydrant and Sewer Use Charge. Purchaser shall assume
               ----------------------------------
all water, hydrant and sewer use charges at the time of closing with an
adjustment made between the Purchaser and Seller as to the prepaid or unbilled,
as the case may be. If the water, hydrant and sewer assessment or use charge
rate shall not have been set as of the Closing Date, said water, hydrant and
sewer use charges shall be assumed on the basis of the most recently
ascertainable bill for such water, hydrant and sewer use. Such water, hydrant
and sewer use charge shall be adjusted, if necessary, when the actual water,
hydrant and sewer use charge bills for the period shall become available, and
the appropriate credit or payment shall be made between Seller and Purchaser
upon demand of either party.

          (vi). Tenant Deposits. All amounts held by Seller as refundable
                ---------------
tenant deposits, and all interest thereon as, required by law under the leases
and tenancies shall be credited and assigned to Purchaser at the time of the
closing, which deposits may include, without limitation, security deposits, key
deposits or pet deposits. Purchaser herein agrees to assume all responsibility
from and after the Closing Date for such refundable tenant deposits and the
interest thereon upon receipt by Purchaser of an Assignment of Leases and
receipt or credit for the security deposits.

7. Final Inspection.
   ------------------

     The Purchaser shall have the right to make a final inspection of the
Property during the week preceding the closing and agrees to notify Seller of
the time and date of said final inspection at least twenty-four (24) hours prior
to the time and date of said final inspection.

8. Leases.
   --------

     Seller agrees to deliver to Purchaser copies of all leases, lease
extensions and lease modifications affecting the Property within ten (10) days
after receipt of a fully executed contract with the deposit required herein. In
the event any portion of the Property is subject to an oral or month to month
lease the Seller shall inform the Purchaser .of the circumstances of said oral
or month to month lease and agrees to set forth in writing the terms of such
occupancy and to deliver same to the Purchaser within said ten (10) days.



                                       -4-

<PAGE>

9. Title.
   ------

     (a). Purchaser, at its sole cost and expense shall promptly examine the
title to the Property and obtain current searches (a "UCC Search") of all
uniform Commercial Code financing statements filed with the Secretary of the
State of Connecticut against Seller and the Property, or either or them relating
to the Property. If Purchaser's examination of title to the Property discloses
any objection to title affecting marketability, or if Purchaser's UCC Search
reveals any claim or lien against Seller or the Property, Purchaser shall notify
Seller of any such objection within ten (10) days of receipt of its search. If
Seller, after making reasonable efforts to do so (including, without limitation,
the payment of money to obtain the release or discharge of liens or other
encumbrances securing the payment of money), shall be unable to remove or
correct any such title objection within ten (10) days prior to closing, Seller
shall so notify Purchaser, and Purchaser, at its option, may either (a) accept
such title as Seller can then convey without reduction of the Purchase Price or
any credit against the same or (b) terminate this Agreement, in which event
neither party shall have any further rights or obligations under this Agreement.

     (b). It is understood and agreed that the title herein required to be
conveyed by the Seller shall be marketable and the marketability thereof shall
be determined in accordance with the Standards of Title of the Connecticut Bar
Association now in force. It is also agreed that any and all defects in or
encumbrances against the title, which come within the scope of said Title
Standards, shall not constitute a valid objection on the part of the Purchaser,
if such Standards do not so provide; provided the Seller furnishes any
affidavits or other instruments which may be required by the applicable
Standards. If, at the time of closing, the Seller shall be unable to convey
marketable title to said Property to the Purchaser, then the Purchaser may elect
to accept such title as Seller can convey, upon payment of the Purchase Price,
or may reject the deed conveying such unmarketable title. Upon such rejection,
all sums paid as a Deposit shall be repaid to Purchaser without interest. Upon
such rejection, this Agreement shall terminate and become null and void and the
parties hereto shall be released and discharged of all further claims and
obligations to each other.

     Purchaser shall have exclusive occupancy and possession of the Property on
the date of the closing subject to the rights of the tenants then in possession.
Seller agrees to deliver all keys in Seller's possession to the Purchaser on the
date of the closing. Seller agrees to maintain or have the grounds maintained in
reasonably the same condition as they exist on the date of execution of this
Agreement until the date of the closing.

12. Representations: Condition of Property
    ---------------------------------------

     Purchaser hereby acknowledges and represents that neither Seller nor any
person or party on behalf of Seller has made any representation of any nature
whatsoever upon which Purchaser has relied in entering into the Agreement or,
upon which Purchaser shall rely in consummating the transactions described in or
contemplated by this Agreement and that Purchaser shall accept delivery of title
to the Property in such condition as the Property shall be as of the date of
this Agreement. Purchaser further acknowledges and represents that it is
entering into this Agreement and shall perform all of its obligations hereunder
and consummate the transactions described in or contemplated by this Agreement
solely as a result of Purchaser's own inspections and investigations. The
Purchaser represents that the Purchaser has examined the Property and is
satisfied with the physical condition thereof and that neither Seller nor any
representative of Seller has made any representation or promise other than those
expressly stated herein upon which Purchaser has relied in making this
Agreement. Notwithstanding the foregoing, however, Seller hereby represents and
warrants to Purchaser as to the following matters, each of which is so warranted
to be true and correct as of the date hereof and only to the date hereof which
truth and correctness shall be a condition precedent to Purchaser's obligation
to close title and Seller agrees that it will not take any




                                       -7-

<PAGE>

action between the date hereof and the closing date which would result in any of
the foregoing representations becoming untrue in any material respect:

     (a). Seller is the owner of and has a good and marketable title to the
Property.

     (b). Seller has not entered into any other contract to sell or granted any
option or right of first refusal to purchase the Property, or any portion
thereof except to Purchaser.

     (c). The Property shall not be in violation of any ordinance, municipal
regulation, public or private law or restrictions at the time of the closing.

     (d). See Schedule B attached hereto.
              ----------

13. Risk of Loss.
    --------------

     The risk of loss or further damage to the Property by fire or any other
casualty or cause beyond the Seller's control in an amount independently
appraised at less than $2,000.00 or the taking of all or a portion of the
Property by Condemnation, eminent domain or other governmental acquisition
proceedings, in advance of the Closing Date shall be borne by Seller. In the
event of any damage, Seller shall have a reasonable time within which to repair
or replace such Damage. In the event of Seller's default of such repair or
replacement within a reasonable time, or in the event that any loss or further
damage to the Property exceeds the amount of $2,000.00 or that any such taking
by condemnation, eminent domain or other governmental acquisition proceeding, in
Purchaser's judgment, shall in any manner impair the Purchaser's intentions as
contemplated by this Agreement or the feasibility thereof as contemplated
herein, Purchaser shall have the right:

     (a). to terminate this Agreement and receive back all amounts paid as a
Deposit on the Purchase Price, plus interest thereon, in which event neither of
the parties hereto shall have any further rights or obligations hereunder; or

     (b). to accept the Property as provided in this Agreement without any
reduction of the Purchase Price, in which event Purchaser shall be entitled to
an assignment from Seller of all insurance proceeds or condemnation or other
award due or payable on account of such loss or damage or taking less any amount
actually expended by Seller in connection with the repair (including temporary
repair) or replacement of such damage plus the amount of any deductible, not to
exceed the amount of the loss.

14. Brokerage.
    -----------

     The parties hereto mutually warrant and represent that DOW REALTY CO. is
the sole broker who negotiated the sale of the Property and a commission or fee
shall be due as a result of this Agreement or the purchase contemplated hereby,
which commission shall be paid by the Seller. Seller covenants and agrees to
indemnify and hold Purchaser harmless of, from and against all claims, costs,
damages and expenses, including, without limitation, reasonable attorney's fees
and court costs, which Purchaser may suffer or incur as a result of claims made
or suits brought by any other broker, agent or for a commission based on
dealings or alleged dealings with Seller with respect to the purchase of the
Property. Purchaser agrees to indemnify and hold Seller harmless of, from and
against all claims, costs, damages and expenses, including, without limitation,
reasonable attorney's fees and court costs, which Seller may suffer or incur as
a result of claims made or suits brought by any broker, agent or finder except
as named herein for a commission based on dealings with Purchaser with respect
to the purchase of the Property.

<PAGE>

15. Default: Liquidated Damages.
    -----------------------------

     In the event that the sale of the Property fails to close as a result of
any material act or omission on the part of the Purchaser and the Seller is not
in default, the Deposit shall be immediately paid over to the Seller by the
Seller's attorney on the date of the scheduled closing. Seller shall be entitled
to retain said Deposit as liquidated damages. The Seller and Purchaser hereby
agree that the exact extent of damages which the Seller would suffer as a result
of Purchaser's failure to close or as a result of Purchaser's act or omission or
default is incapable of being computed and therefore both the Seller and
Purchaser agree that the sum of the Deposit is the best available computation of
liquidated damages to which the Seller would be entitled. Upon the payment of
the Deposit to the Seller, both the Seller and Purchaser shall be relieved of
further liability under this Agreement.

16. Release of Mortgages:
    ----------------------

     Notwithstanding anything to the contrary contained in this Agreement or any
riders attached hereto, in the event the Seller after due diligence cannot
obtain a release for any existing mortgage on the Property at the time of the
closing of title from the lending institution holding said mortgage, or any
assignee thereof, either because said lending institution will not release the
mortgage without first receiving payment or because the lending institution has
delayed in sending the attorney for the Seller the release of mortgage, then
Purchaser agrees to close title notwithstanding the absence of the release of
mortgage, provided the attorney for the Seller furnishes the attorney for the
Purchaser, at the closing, with the payoff amount and a copy of the payoff check
evidencing that payment of the unreleased mortgage is to be made in full at the
time of the closing, and with an undertaking to make said payment, and further
provided the Purchaser's Title Insurance Company will issue a fee policy at no
additional premium which takes no exception for said mortgage or mortgages.
Seller shall exercise due diligence to obtain any such release or releases and
will upon receipt thereof immediately record the same and forward a copy or
copies thereof to Purchaser's attorney with recording information. If Seller has
not obtained such release within sixty (60) days after closing, he shall give to
Purchaser's attorney the affidavit provided for in Connecticut General Statutes
Section 49-8(a), as amended, together with the necessary recording fee. This
provision shall survive the closing.

17. Acceptance of Deed.
    --------------------

     The delivery and acceptance of the deed described herein shall be deemed to
constitute full compliance with all the tenDs, conditions, covenants and
representations contained herein, or made in connection with this transaction,
except as may herein be expressly provided and except for the warranties of
title.

18. Assignment
    -----------

     Purchaser may assign its rights under this Agreement without the written
consent of the other party.

19. Binding Effect.
    ----------------

This Agreement shall inure to the benefit of and bind the parties hereto and
their respective legal representatives, heirs, administrators, executors,
successors and assigns.

whatsoever shall be made or claimed by Seller or Purchaser, and no notice of any

Purchaser (except with respect to permitted unilateral waivers) shall have any
force or effect whatsoever unless the same is in writing and signed by both the

more parties, the liability of such parties shall be joint and several.

22. Invalidity.
    ------------

unenforceability shall not affect any other provision of this Agreement, but the
remainder of this Agreement and each term and provision of this Agreement shall
be valid and enforceable to the fullest extent permitted by law, subject to such
modification hereof as may be necessitated by such invalidity.
