        and
        the undersigned employee (“Employee”) hereby enter into this Amended
        Performance-Based Restricted Stock Award Agreement, which replaces and

      Matritech,
        Inc.

      

      Amended
        Performance-Based Restricted Stock Award Agreement 

      Incorporated
        Terms and Conditions

      

      1.    Award
        Under Plan.
        This
        award of restricted stock is made pursuant to and is governed by the Company’s
        2002 Stock Option and Incentive Plan (the “Plan”)
        and,
        unless the context otherwise requires, terms used herein shall have the same
        meaning as in the Plan. 

      

      2.    Payment
        of Par Value of Shares.
        The
        Employee, as a condition to this award of restricted stock, agrees to pay
        to the
        Company in cash, contemporaneously with the execution of this Agreement,
        the par
        value of the Shares of restricted stock. The Employee further agrees that
        the
        Company may, in the absence of receipt of cash from the Employee equal to
        the
        par value of the Shares, withhold from the Employee’s wages or other
        remuneration the par value amount. The Company agrees, in the event of a
        forfeiture of Shares of restricted stock under Section 6 hereof due to
        termination of the Employee’s Business Relationship (as defined below) with the
        Company, the Company will repay to the Employee an amount equal to the par
        value
        of the forfeited Shares. 

      

      3.    Custody
        of Restricted Stock.
        Certificates representing the Shares of restricted stock awarded to the Employee
        shall bear appropriate legends noting the restrictions applicable to the
        Shares.
        The original certificates shall be held by the Company until such time as
        the
        underlying Shares are no longer subject to the risk of forfeiture, retention
        obligation and securities law restrictions contained in Sections 4, 5, 6
        and 8
        hereof. The Employee will also provide the Company with a stock power endorsed
        in blank. At such time as the shares are no longer subject to the risk of
        forfeiture, retention obligation and securities law restrictions contained
        in
        Sections 5, 6 and 8 hereof, the Company will deliver to the Employee original
        certificates without restrictive legends thereon. 

      

      4.    Vesting
        of Restricted Stock.
        All
        Shares subject to this Agreement are subject to a substantial risk of forfeiture
        until such Shares have vested in the Employee in accordance with the terms
        of
        this Agreement. The vesting criteria, measurement mechanisms and dates and
        other
        vesting standards are set forth on Appendix A, which is incorporated herein
        by
        reference. If any one of the vesting criteria is fully met, and the Employee
        has
        continuously maintained a Business Relationship (as defined below) with the
        Company through the measurement date of the criterion, the portion of the
        awarded Shares listed on Appendix A relative to that satisfied criterion
        shall
        vest in the Employee and no longer be subject to forfeiture. “Business
        Relationship”
means
        service to the Company or its successor in the capacity of an employee, officer,
        director or consultant. Notwithstanding the foregoing, the Board may, in
        its
        discretion, determine to accelerate the vesting of all or any portion of
        the
        award. 

      

      5.    Retention
        Obligation; Restrictions after Vesting.
        If the
        Employee is an executive officer of the Company at the time of vesting of
        any
        portion of the restricted stock award, the Employee is obligated to retain
        in
        his/her ownership a minimum of fifty (50%) percent of the Shares of Common
        Stock
        of the Company acquired through this restricted stock award to the extent
        that
        the Employee does not then hold by himself/herself or through members of
        his/her

       

      
        
           

        

        
           

          
            

          

        

        
          -2-

        

      

       

      immediate
        family a minimum of [100,000/150,000] shares of Common Stock of the Company
        or
        shares of Common Stock of the Company with a value of [2.5/4.0] times the
        Employee’s base salary, whichever is the lower standard; provided, however, that
        there shall be excluded from the retention obligation any Shares the Employee
        sells (or, in the discretion of the Company, tenders back to the Company)
        to pay
        withholding taxes due on account of the lapse of restrictions on the Shares
        of
        restricted stock. Certificates representing the shares which remain subject
        to
        the retention obligation shall continue to be held by the Company until they
        are
        no longer subject to the retention obligation. 

       

      6.    Termination
        of Business Relationship.
        Except
        as set forth in Section 7 hereof, if the Employee’s Business Relationship with
        the Company ceases, voluntarily or involuntarily, with or without cause,
        prior
        to the vesting of any portion of this award, no further portions of this
        award
        will vest and the Employee shall forfeit all Shares subject to this restricted
        stock award not vested at the date of such termination of the Employee’s
        Business Relationship with the Company. Any determination under this Agreement
        as to the status of a Business Relationship or other matters referred to
        above
        shall be made in good faith by the Board of Directors of the Company.

      

      7.    Death;
        Disability.
        

      

      (a)    Death
        or Disability.
        If the
        Employee ceases to maintain a Business Relationship with the Company by reason
        of his/her disability or death, the Shares of restricted stock subject to
        this
        Agreement shall vest in the Employee (or in his/her estate in the event of
        his/her death) and the restrictions (except those contained in Section 8
        hereof)
        and substantial risk of forfeiture shall lapse, according to the following
        schedule:

      
        	
              	(i)	
                if
                  the death or disability occurs during the first year after the
                  date of
                  this Agreement, 30% of the Shares will vest;
                  and

              

      

      
        	
              	(ii)	
                if
                  the death or disability occurs during the second year after the
                  date of
                  this Agreement, 100% of the Shares will vest.

              

      

      For
        purposes hereof, “disability”
means
        “permanent
        and total disability”
as
        defined in Section 22(e)(3) of the Internal Revenue Code. 

      

      (b)    Retirement
        with Consent of the Company.
        If the
        Employee retires from his/her Business Relationship with the Company with
        the
        consent of the Company after the Employee has reached age 62, the shares
        of
        restricted stock subject to this Agreement shall vest in the Employee and
        the
        restrictions (except those contained in Section 8 hereof) and substantial
        risk
        of forfeiture shall lapse, according to the following schedule:

      
        	
              	(i)	
                if
                  the retirement occurs during the first year after the date of this
                  Agreement, 30% of the Shares will vest;
                  and

              

      

      
        	
              	(ii)	
                if
                  the retirement occurs during the second year after the date of
                  this
                  Agreement, 100% of the Shares will vest.

              

      

      

      (c)    Change
        of Control. In
        the
        event of an Acquisition (as defined herein) prior to the full vesting of
        this
        award, the vesting of the award shall be accelerated and the Shares of the
        restricted stock subject to this Agreement shall vest in the Employee, and
        the
        restrictions (except those contained in Section 8 hereof) and substantial
        risk
        of forfeiture shall lapse, at the 

       

      
        
           

        

        
           

          
            

          

        

        
          -3-

        

      

       

      moment
        immediately preceding the consummation of the Acquisition, according to the
        following schedule:

      
        	
              	(i)	
                if
                  the Acquisition occurs during the first year after the date of
                  this
                  Agreement, 30% of the Shares will vest;
                  and

              

      

      
        	
              	(ii)	
                if
                  the Acquisition occurs during the second year after the date of
                  this
                  Agreement, 100% of the Shares will vest.

              

      

      Notwithstanding
        the foregoing, the Board of Directors of the Company may, in its discretion,
        fully vest all the Shares in the event of an Acquisition regardless of the
        date
        of the Acquisition. For purposes of this Plan, an “Acquisition”
shall
        mean: (x) the sale of the Company by merger in which the shareholders of
        the
        Company in their capacity as such no longer own a majority of the outstanding
        equity securities of the Company (or its successor); or (y) any sale of all
        or
        substantially all of the assets or capital stock of the Company (other than
        in a
        spin-off or similar transaction) or (z) any other acquisition of the business
        of
        the Company, as determined by the Board.

      

      8.    Securities
        Laws Restrictions on Resale.
        Until
        registered under the Securities Act of 1933, as amended, or any successor
        statute (the “Securities
        Act”),
        the
        Shares will be illiquid and will be deemed to be “restricted securities” for
        purposes of the Securities Act. Accordingly, such shares must be sold in
        compliance with the registration requirements of the Securities Act or an
        exemption therefrom and may need to be held indefinitely. Unless the Shares
        have
        been registered under the Securities Act, each certificate evidencing any
        of the
        Shares shall bear a restrictive legend specified by the Company. 

      

      9.    Ownership
        Rights.
        Subject
        to the restrictions set forth herein, the Employee is entitled to all voting
        and
        ownership rights applicable to the Shares, including the right to receive
        any
        dividends that may be paid on the shares, whether or not vested. Each dividend
        payment will be made no later than the end of the calendar year in which
        the
        dividends are paid to shareholders of that class of stock or, if later, the
        15th
        day of
        the third month following the date of the dividends are paid to shareholders
        of
        that class of stock.

      

      10.    Award
        Not Transferable.
        This
        award is not transferable or assignable except by will or by the laws of
        descent
        and distribution. 

      

      11    No
        Obligation to Continue Business Relationship.
        Neither
        the Plan, this Agreement, nor the restricted stock award imposes any obligation
        on the Company to continue the Employee in employment or other Business
        Relationship.

      

      12.    No
        Severance or Termination Rights.
        Awards
        do not form part of an Employee’s contract of employment and do not entitle an
        Employee to any benefit other than that granted under this Agreement. Any
        benefits granted under this Agreement are not part of an Employee’s ordinary
        salary, and shall not be considered as part of such salary for pension purposes
        or in the event of severance, redundancy or resignation. If Employee’s
        employment is terminated for whatever reason the Employee agrees that he/she
        shall not be entitled by way of damages for breach of contract, dismissal
        or
        compensation for loss of office or otherwise to any sum, shares or other
        benefits to compensate for the loss or diminution in value of any actual
        or
        prospective right, benefits or expectation under or in relation to this
        Agreement.

       

      
        
           

        

        
           

          
            

          

        

        
          -4-

        

      

      

      13.    Adjustments.
        This
        award is subject to adjustment, as is expressly provided in the Plan, with
        respect to certain changes in the capitalization of the Company.

      

      14.    Withholding
        Taxes.
        If the
        Company in its discretion determines that it is obligated to withhold any
        tax in
        connection with the vesting of any portion of the Shares or the release of
        any
        restrictions applicable to the Shares, the Employee hereby agrees that the
        Company may withhold from the Employee’s wages or other remuneration the
        appropriate amount of tax. At the discretion of the Company, the amount required
        to be withheld may be withheld in cash from such wages or other remuneration
        or
        in kind from the Common Stock or other property otherwise deliverable to
        the
        Employee on vesting or lapse of restrictions on the Shares. The Employee
        further
        agrees that, if the Company does not withhold an amount from the Employee’s
        wages or other remuneration sufficient to satisfy the withholding obligation
        of
        the Company, the Employee will make reimbursement on demand, in cash, for
        the
        amount underwithheld. The Employee further agrees to indemnify the Company
        for
        the Employee’s portion of any social insurance obligations or taxes arising
        under any foreign law with respect to the grant of this restricted stock
        award,
        the vesting of the restricted stock or the sale or other disposition of the
        restricted stock.

      

      15.    Provision
        of Documentation to Employee.
        By

                          EXTENSION OF LEASE AGREEMENT
                          ----------------------------

     THIS EXTENSION OF LEASE AGREEMENT made and entered into as of the 11th day
of November, 2005, by and between Roger G. Little, Trustee of SPI-Trust, under a
declaration of trust, dated May 3, 1976, and recorded with Middlesex South
District Registry of Deeds, Book 12970, Page 625, having a mailing address at
One Patriots Park, Bedford, Massachusetts 01730 (the "Landlord") and Spire
Corporation, a Massachusetts corporation, with an address at One Patriots Park,
Bedford, Massachusetts 01730 (the "Tenant").

                              W I T N E S S E T H:

     WHEREAS, Tenant is presently in possession of the Premises (as herein
defined) under that certain Sublease dated as of November 25, 1985 by and
between Millipore Corporation, a Massachusetts corporation, as Lessor and
Tenant, as Lessee, as amended (the "Sublease");

     WHEREAS, Tenant wishes to remain in possession of the Premises upon the
expiration of the Sublease and wishes to lease the Premises directly from
Landlord; and

     WHEREAS, Landlord wishes to lease the Premises to Tenant.

     NOW THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Landlord and Tenant hereby enter
into this Extension of Lease Agreement upon the terms and conditions set forth
herein.

     1. Lease of Premises. Subject to all of the provisions herein contained,
and in consideration of the rentals to be paid to Landlord by Tenant, and the
other covenants and agreements to be kept and performed by Tenant hereunder, as
hereinafter set forth, Landlord hereby leases to Tenant, and Tenant hereby
leases from Landlord, the premises consisting of approximately 77,037 square
feet (the "Premises") shown on the plan attached hereto as Exhibit A within the
building (the "Building") situated in Bedford, Middlesex County, Massachusetts,
located on the real estate owned by Landlord on the Westerly side of Wiggins
Avenue, known as Patriots Park (the "Real Estate"). The Tenant shall have the
right to use in common with others the common areas serving the Premises,
including without limitation, stairs, lobbies, elevators, hallways, corridors,
restrooms, cafeteria and entrances and exits in the Building and all access
roads, driveways, parking areas, loading docks, sidewalks, landscaped areas,
trash pick-up areas, recreational areas and other amenities which are located
within the Real Estate.

     If Tenant desires during the term of this Extension of Lease Agreement to
lease additional space within the Building which is then unoccupied and adjacent
to the Premises as then currently configured, it shall provide Landlord written
notice of its desire to add such space to the Premises. The Expansion Notice
(the "Expansion Notice") shall identify the location and size of the space which
Tenant desires to add to the Premises (the "Proposed Expansion Space") and the
date on which it desires to add the Proposed Expansion Space to the Premises
(the "Expansion Date"), which date shall be no less than thirty (30) days from
the date of the Expansion Notice. Within ten (10) days after receipt of the
Expansion Notice, Landlord shall notify Tenant whether it accepts or

                                       1
<PAGE>

rejects Tenant's request for the addition of the Proposed Expansion Space to the
Premises. If Landlord rejects such request, this Lease shall continue in full
force and effect without the addition of the Proposed Expansion Space to the
Premises. If Landlord accepts the Expansion Notice, then effective upon the
Expansion Date the Premises shall be automatically amended to include such
Proposed Expansion Space in its then "AS IS" condition and the annual Base
Rental hereunder shall be increased by the product of (x) the square footage of
the space so added and (y) $16.12. Tenant shall be responsible for any
alterations, additions and improvements, necessary to prepare the Proposed
Expansion Space for its occupancy, and the same shall be performed in accordance
with the terms of this Extension of Lease Agreement. The monthly payment of Base
Rental shall be adjusted to reflect the increase in annual Base Rental.

     2. Term. The term of this Extension of Lease Agreement shall be for a
period of two (2) years, beginning on the 1st day of December, 2005 (the
"Commencement Date") and, unless terminated as herein provided, continuing until
expiration on the 30th day of November, 2007.

     3. Intentionally Omitted.

     4. Rent. For the use and occupancy of the Premises Tenant hereby covenants
and agrees to pay to or for the account of Landlord as rental ("Rental"),
without deduction or offset, the following amounts:

     (a) An annual fixed rental calculated at the rate of $16.12 per square foot
of the Premises, being One Million Two Hundred Forty One Thousand Eight Hundred
Thirty Six Dollars and Forty Cents ($1,241,836.40) per year (hereinafter the
"Base Rental"), due and payable in advance in monthly installments of One
Hundred Three Thousand Four Hundred Eighty Six Dollars and 33 Cents
($103,486.36) at Landlord's business premises located at Patriots Park, Bedford,
Massachusetts, on the first day of each and every calendar month during the term
of this Extension of Lease Agreement; a prorated and proportional rent shall be
due for any periods of less than a calendar month at the commencement and
expiration of the lease term, all without set off or deduction except as may be
required by law in order to preserve any claim of Tenant thereto.

     (b) Subject to Landlord's obligations set forth in Section 4(e) below, all
real estate taxes, or taxes in the nature of real estate taxes, or taxes
assessed in lieu of or in addition thereto (except income taxes of general
application, inheritance, estate or like taxes) including special and general
assessments, however the same may be designated, levied or to be levied by any
taxing authority upon the Building or Real Estate ("Real Estate Taxes")
throughout the entire term of this Extension of Lease Agreement; the same shall
be paid by Tenant directly to such taxing authority upon receipt of the tax bill
but in no event later than fifteen (15) days prior to the last date upon which
such taxes may be paid without interest or penalty. If the first or last year of
the term of this Extension of Lease Agreement shall not be co-extensive with the
tax year the amount of taxes payable by Tenant hereunder for such years shall be
prorated in proportion to the period of effectiveness of the Extension of Lease
Agreement during such years. Tax receipts shall be furnished to Landlord by
Tenant from time to time upon request to show Tenant's compliance herewith on a
current basis. If requested by any first mortgagee of the Premises, Tenant
agrees to instead make monthly deposits to such mortgagee on account of such
taxes in an amount reasonably estimated to be sufficient to pay such taxes when
they become due, provided that such deposits are maintained in a separate
account and any interest payable with respect thereto shall be payable to
Tenant.

                                       2
<PAGE>

     (c) Subject to Landlord's obligations set forth in Section 4(e) below, all
costs of electricity, gas, fuel, water and sewage services assessed against the
Premises, Building and Real Estate ("Utility Costs").

     (d) Subject to Landlord's obligations set forth in Section 4(e) below, all
other costs and expenses of every kind with respect to operation, maintenance,
repair of the Premises, Building and Real Estate but excluding Direct Landlord
Costs (as defined in Section 25 below) ("Operations Costs") and insurance of the
Premises, Building and Real Estate ("Insurance Costs").

     (e) Notwithstanding Tenant's obligations to pay Real Estate Taxes (as
defined in Section 4(b) above), Utility Costs (as defined in Section 4(c)
above), Operations Costs (as defined in Section 4(d) above) and Insurance Costs
(as defined in Section 4(d) above) as set forth in this Section 4, Landlord
shall be responsible for the payment of the portion of such Real Estate Taxes
(as defined in Section 4(b) above), Utility Costs (as defined in Section 4(c)
above), Operations Costs (as defined in Section 4(d) above) and Insurance Costs
(as defined in Section 4(d) above) which are not solely allocable to the
Premises in accordance with Section 25 below.

     Landlord shall establish and maintain a separate bank account with a
financial institution reasonably acceptable to Tenant for the purpose of holding
funds sufficient to satisfy Landlord's obligations under this Section 4(e) with
respect to Real Estate Taxes, Utility Costs, Operating Costs and Insurance Costs
(the "Landlord's Share Escrow Account"). The Landlord's Share Escrow shall be
initially funded with, and shall at all times maintain a balance of no less
than, an amount reasonably estimated by Tenant to satisfy three (3) months of
Landlord's obligations with respect to Real Estate Taxes, Operating Costs,
Insurance Costs and Utility Costs (the "Minimum Balance"). Tenant shall be
listed as the sole entity having withdrawal rights with respect to such account
and Tenant shall withdraw such funds if, as and when it deems necessary to
satisfy Landlord's obligations hereunder. In addition to the Minimum Balance,
Landlord shall make monthly payments equal to one-twelfth of Landlord's Share of
such Real Estate Taxes, Operating Costs, Insurance Costs and Utility Costs
(collectively, "Expenses") for the calendar year into the Landlord's Share
Escrow Account on the first day of each and every calendar month during the Term
of this Lease, commencing on the Commencement Date. The monthly amount so to be
paid to the Landlord's Share Escrow Account may be modified from time to time to
provide Tenant with a sum equal to Landlord's required payment, as reasonably
estimated by Tenant from time to time, on account of Real Estate Taxes,
Operating Costs, Insurance Costs and Utility Costs for the current operating
year (January 1 through December 31; the "Operating Year"). Within a reasonable
period after the end of an Operating Year, Tenant shall provide Landlord a
reasonably detailed statement of Expenses for the prior Operating Year. If
estimated payments theretofore made by Landlord for the Operating Year exceed
the sum of (x) the required payment of Landlord's Share (as defined in Section
25 below) of the Expenses and (y) the Minimum Balance, Tenant shall credit the
amount of such excess against subsequent obligations of Landlord on account of
Expenses (or promptly refund such excess if the Term of this Lease has ended and
Landlord has no further obligation to Tenant); but if the required payments on
account thereof for such Operating Year are greater than estimated payments
theretofore made on account thereof for such Operating Year, Tenant shall have
the election, at its sole discretion, to withdraw such funds from the Minimum
Balance or to require Landlord to credit the amount of underpayment against
subsequent obligations of Tenant with respect to Rental hereunder. Tenant shall
have the right to increase or decrease the amount of such monthly installments
or the Minimum Balance from time to time. In the event the Landlord's Share
Escrow Account falls below the Minimum Balance, Landlord shall deposit such
funds into the Landlord's Share Escrow Account to restore the amount in such
account

                                       3
<PAGE>

to the Minimum Balance. Promptly after the expiration or early termination of
the term, Tenant shall return the balance of the Landlord's Share Escrow Account
to Landlord.

     (f) In no event shall Tenant incur, or be responsible for the payment of,
any Direct Landlord Costs (as defined in Section 25 below) or perform any
obligation associated with such costs.

     5. Intentionally Omitted.

     6. Net Lease. It is the intention of the parties hereto that this is a net
lease and that, subject to Landlords obligations to reimburse Tenant for a
portion of such Real Estate Taxes, Utility Costs and Operations and Insurance
Costs as set forth in Section 4(e) above, all costs of ownership, maintenance
and use of the Premises, the Building and the Real Estate shall be paid by
Tenant in addition to the fixed rent specified above and other sums payable by
Tenant hereunder (each of which shall be treated as Rental, for non-payment of
which Landlord shall have all rights which Landlord would have for non-payment
of fixed rent hereunder), provided, however, that Landlord shall be responsible
for maintenance and repair of structural portions of the Building in accordance
with Section 8(d) hereof. Tenant shall pay to or on behalf of Landlord, through
the term of this Extension of Lease Agreement, the rent and other payments
hereunder, free of any charges, assessments, impositions or deductions of any
kind, all of which Tenant shall pay or discharge, without abatement, deduction
or set off, and Landlord shall not be required to make any payment of any kind
whatsoever hereunder (whether due to circumstances now existing or beyond
present contemplation of the parties), except as herein otherwise set forth. The
rights of the parties in the event of a casualty to the Premises shall be
governed by Section 15 hereto.

     7. Tenants Covenants. Subject to Landlord's obligations set forth in
Section 4(e) above, Tenant further covenants and agrees as follows:

     (a) Except as set forth in Section 8(d) below, to maintain the Premises,
Building and Real Estate including the doors and windows thereof in good repair,
condition and order in accordance with good maintenance practices; and to yield
peaceable possession to Landlord of the Premises at termination or expiration of
this Extension of Lease Agreement free of all tenants and occupants in as good
repair and condition as at occupancy by Tenant or may be put thereafter except
for ordinary wear and tear, obsolescence, and damage caused by fire (unless
caused by Tenant's negligence or default and not insured against or required to
be insured against hereunder) or the elements.

     (b) To comply fully with any applicable statutes, ordinances, and lawful
regulations, rules or orders pertaining to the Premises, Real Estate and
Building and to the activities conducted thereon, to comply with all applicable
rules or conditions reasonably imposed with respect to the Premises by any
insurance carrier, and to prevent the existence of any nuisance, or the
violation of any statute, ordinance or valid rule, order or regulation with
respect thereto and to save Landlord harmless from any failure to do so.

     (c) To keep the Building and Premises insured to the extent of building
replacement costs, against loss or damage by fire, windstorm, hail, explosion
and the other risks included in extended coverage policies from time to time,
subject, however to a "deductible" clause in the amount of $50,000 or such other
amount as Tenant shall reasonably request and Landlord shall

                                       4
<PAGE>

approve, which approval shall not be unreasonably withheld or delayed; all of
such policies shall name as insured Landlord, any first mortgagee to the
Premises and Tenant, as their respective interests may appear and shall provide
that they may not be cancelled without at least fifteen (15) days' prior written
notice to Landlord (provided, that such additional notice does not result in the
imposition of additional premiums or charges by such insurer). Tenant agrees to
furnish Landlord with a certificate by the insurer as to the existence thereof,
together with a copy of such policy. Tenant may procure such insurance under a
so-called blanket policy insuring other locations of the Tenant, provided
however, that such policy shall provide on its face that such portion of the
face amount as is required by this Extension of Lease Agreement is payable with
respect to covered loss relating to the Premises and is not affected by losses
on other premises.

     (d) To the fullest extent permitted by law, to indemnify Landlord fully
against and to save Landlord harmless from loss, liability, costs, expense,
attorney's fees and court costs, arising directly or indirectly from any claim
or lawsuit by any person, firm, corporation, association or governmental agency
or authority whomsoever, including (but not limited to) Tenant's officers,
agents, employees or invitees, for damages assertedly sustained to person or
property by reason of any activity conducted by Tenant upon the Premises, or of
any breach by Tenant, its officers, agents, employees, or invitees of the terms,
provisions and conditions of this Extension of Lease Agreement, or occurring
upon the Premises or areas controlled by the Tenant by reason of the conduct of
the Tenant, its officers, agents, employees and invitees, regardless of the
merit or lack of merit of any such claim or lawsuit, of the fault or lack of
fault on the part of Landlord and regardless of the amount of insurance carried;
and further, to procure and keep in force, at Tenant's sole expense, public
liability insurance covering the Premises, with minimum limits of at least
$5,000,000.00 for the death of or bodily injury to any one person, and
$5,000,000.00 for the death of or bodily injury to any number of persons
resulting from the same event, and of $l,250,000.00 for property damage naming
Landlord, any first mortgagee of the Premises and Tenant as insureds, as their
respective interests may appear, provided that if greater coverage limits are
normally carried under similar circumstances, Tenant agrees to increase such
coverage limits appropriately.

     (e) To use its best efforts to prevent the filing or imposition of any lien
of any kind whatsoever upon or against the Premises based upon or arising out of
Tenant's actions, except by Landlord or with Landlord's prior written consent
and in the event of the filing or imposition of any such lien, to discharge same
or to obtain a surety bond sufficient to discharge same within 30 days following
the date of any such filing or imposition.

     (f) To permit Landlord to enter the Premises during normal business hours
and, subject to Tenant's reasonable security and confidentiality requirements,
where such entry will not unreasonably disturb or interfere with Tenant's use of
the Premises and the operation of Tenant's business, to examine, inspect,
provide services or make repairs, replacements, changes or alterations as set
out in this Extension of Lease Agreement, and to take such steps as Landlord may
reasonably deem necessary for the safety, improvement or preservation of the
Premises. Landlord shall give reasonable notice to Tenant prior to any such
entry, except in the case of an emergency, but no such entry shall constitute an
eviction or entitle Tenant to any abatement of Rental.

     (g) In the event that Tenant shall fail to perform any act required by the
foregoing covenants and such failure shall continue for a period of 30 days
after notice thereof from Landlord, Landlord may (but shall not be obligated to
do so) perform such act without waiving or releasing Tenant from any of its
obligations with respect thereto. Landlord shall be entitled to recover from
Tenant all sums paid or costs incurred in performing such acts on demand.

                                       5
<PAGE>

     (h) To perform all maintenance, repairs and replacements necessary to keep
in good condition and working order (a) the heating, ventilating, air
conditioning, plumbing, security, electrical, life safety and other mechanical
systems and equipment serving the Building , (b) the trees, shrubs, plants,
landscaping, on the Real Estate or otherwise, serving the Building, and (c) the
parking lot, driveways and walkways necessary for access to the Building.

     (i) To perform all clearance and removal of snow and ice from the parking
areas, driveways and walkways of the Real Estate for safe use of such parking
areas and safe access to the Building by Tenant and other occupants of the
Building, if any, and their employees, agents, contractors and invitees.

     8. Landlord's Covenants. The Landlord hereby represents, warrants,
covenants and agrees as follows;

     (a) That Landlord has good and marketable title to the Premises, free and
clear of all liens and encumbrances which would impair Tenant's ability to use
and enjoy the Premises; as of the date hereof, title to the Premises is
adequately insured with a reputable title insurance company under a policy in
form and amount acceptable to Tenant and Landlord has full right and authority
to lease the Premises and to carry out its obligation under this Extension of
Lease Agreement.

     (b) To the best of Landlord's knowledge, the Premises may be used for
warehouse, office, research and development and manufacturing purposes under all
applicable zoning, wetlands, conservation and other ordinances and regulations.

     (c) Intentionally Omitted.

     (d) To maintain all structural portions of the Building including
foundations, roofs, exterior walls, structural members and other supporting
structures, in good repair, condition and order; provided, however, that
Landlord's responsibility for repair and maintenance of roofs shall exclude
responsibility for repair of (i) leaks occurring by reason of roof penetrating
structures installed or constructed by Tenant after December 1, 1985 (the
Commencement Date of the Sublease (as defined above)), (ii) isolated minor leaks
properly repaired by simple patching procedures (as opposed to a leak or series
of leaks which properly require replacement or restoration of all or any portion
of a roof), or (iii) any repairs required by reason of the negligence or default
of Tenant, its officers, agents, employees, and invitees except to the extent
that Landlord shall be insured against the same and receive the proceeds of such
insurance and Landlord's mortgagees shall not retain the proceeds of such
insurance.

     (e) To give Tenant prompt notice of the name and mailing address of any
mortgagee or holder of a first mortgage lien with respect to the Premises and of
any change therein.

     9. Subletting. Subject to all of the provisions of this Extension of Lease
Agreement, all or any portion of the Premises may be sublet by Tenant provided
the Tenant obtains the prior written consent of the Landlord therefor, which
consent, shall not be unreasonably withheld, conditioned or delayed; but Tenant
shall have no right to assign this Extension of Lease Agreement

                                       6
<PAGE>

nor any of its rights hereunder (other than assignment to an entity controlling,
controlled by or under common control with Tenant or pursuant to the sale of the
entire business and assets of the division of Tenant occupying the Premises
provided, however, that without the consent of Landlord no such assignment shall
relieve Tenant of liability hereunder), nor may same be assigned or pass to
another by operation of law, and any attempt to so assign, without the express
prior consent of Landlord, shall be utterly void. Tenant further agrees to
promptly provide Landlord with the name and address of the sublessee and a
description of the terms of the sublease arrangement. Tenant shall, however, be
entitled to retain any premium over the Rental provided hereunder which it
receives under any such sublease.

     10. Signs. Tenant shall be entitled to erect reasonable ground and building
signs, subject to approval of Landlord, which shall not be unreasonably
withheld, provided, however, Tenant's signs that are presently existing and/or
installed on the Premises, the Building or Real Estate are hereby deemed
approved by Landlord. All signs installed by Tenant shall comply with all
requirements of appropriate governmental authorities, and all necessary permits
or licenses shall be obtained by Tenant. Tenant shall maintain all signs in good
condition and repair at all times, and shall save Landlord harmless form injury
to person or property, arising from the erection and maintenance of said signs.
Upon vacating the Premises, Tenant shall remove all signs and repair all damage
caused by such removal.

     11. Alterations and Improvements by Tenant. (a) Tenant shall have the right
during the continuance of this Extension of Lease Agreement to make such
alterations, changes and improvements to the Premises as may be proper and
necessary for the conduct of Tenant's business and for the full beneficial use
of the Premises. Tenant shall not make any structural change in the Premises
without first having obtained Landlord's written consent thereto, without
limitation Landlord may condition any such consent by reserving the right to
require the Premises to be restored to the same condition they were in prior to
the making of any such structural change. Tenant shall pay all costs and
expenses of such alterations, changes, and improvements, shall make the same in
a good and workmanlike manner, and in accordance with all applicable laws,
codes, and building regulations, and shall, prior to the making of such
alterations, changes, and improvements, assure Landlord, in form satisfactory to
Landlord, that payment for the same will be made by Tenant. Tenant hereby
completely and fully indemnifies Landlord against any Mechanic's Liens or other
liens or claims in connection with the making of such alterations, changes, and
improvements. Any liens arising out of such alterations, changes, and
improvements shall be discharged of record by Tenant within thirty (30) days
after the same have been filed, Tenant shall pay any and all taxes relating to
its personal property, business, or improvements and alterations constructed as
provided in this Section 11.

     (b) Except as otherwise provided, all signs, furnishings, trade fixtures
and other removable equipment installed in the Premises by Tenant and paid for
by Tenant shall remain, the property of Tenant and shall be removed by Tenant
upon the termination of this Extension of Lease Agreement provided that any of
such as are affixed to the Premises and require severance shall be removed at
Tenant's cost, and Tenant shall immediately repair any damage caused by such
removal.

     12. Waiver of Subrogation. Each of Landlord and Tenant hereby releases the
other from any and all liability or responsibility to the other or anyone
claiming through or under them by way of subrogation or otherwise for any loss
or damage to property caused by fire or any other perils insured or required to
be insured against in policies of insurance covering such property, even if

                                       7
<PAGE>

such loss or damage shall have been caused by the fault or negligence of the
other party, or anyone for whom such party may be responsible, including any
sub-tenants or other occupants of the Premises; provided, however, that this
release shall be applicable and in force and effect only to the extent that such
release shall be lawful at that time and in any event only with respect to loss
or damage occurring during such times as the releasor's policies shall contain a
clause or endorsement to the effect that any such release shall not adversely
affect or impair said policies or prejudice the right of the releasor to recover
thereunder and then only to the extent of the insurance proceeds payable under
such policies. Each of Landlord and Tenant agrees that it will request its
insurance carriers to include in its policies such a clause or endorsement. If
extra cost shall be charged therefor, each party shall advise the other thereof
and of the amount of the extra cost, and the other party, at its election, may
pay the same, but shall not be obligated to do so. If such other party fails to
pay such extra cost, the release provisions of this paragraph shall be
inoperative against such other party to the extent necessary to avoid
invalidation of such releasor' s insurance.

     13. Subordination. (a) Tenant, upon demand by Landlord, agrees to give a
waiver of priority of Tenant's lien arising by virtue of the within leasehold
estate, thereby subordinating Tenant's lien in favor of any mortgage loan, or
any refinancing or replacing of a mortgage loan that Landlord may determine
necessary or desirable from time to time, which election may be changed from
time to time. Tenant agrees to execute such instruments as may be required by
any such lending institution or prospective first mortgagee in order to
effectuate such waiver of priority and subordination of Tenant's lien and such
certificates as to the status of this Extension of Lease Agreement and other
matters as such mortgagees shall reasonably require. Tenant shall be bound by
and observe all conditions of said mortgage which shall require the giving of
reports and copies of notices to any such mortgagees, as well as those which
afford such mortgagees the opportunity to cure any default of Landlord hereunder
and, subject to paragraph (b) below, to take possession of the Premises without
liability for any default of the Landlord occurring prior thereto or which
cannot reasonably be cured by such mortgagee not be subject to any offset or
defenses on account thereof nor bound by any prepayment of rent beyond the then
current period. In the event any proceedings are brought for foreclosure, or in
the event of the exercise of the power of sale under any mortgage or deed of
trust, Tenant shall attorn to the purchaser in any such foreclosure or sale and
recognize such purchaser as landlord under this Extension of Lease Agreement.

     (b) Upon the request of Tenant, Landlord shall procure from any such
lending institution or mortgagee an agreement-in-writing, which shall be
delivered to Tenant, providing in substance that so long as Tenant shall
faithfully discharge the obligations on its part to be kept and performed under
the terms of this Extension of Lease Agreement, Tenant's tenancy will not be
disturbed nor this Extension of Lease Agreement affected by any default under
such mortgage, and Tenant agrees that this Extension of Lease Agreement shall
remain in full force and effect even though default in the mortgage may occur.

     14. Limitation of Landlord Liability. (a) If Landlord shall fail to perform
any covenant, term or condition of this Extension of Lease Agreement upon
Landlord's part to be performed and, as a consequence of such default, Tenant
shall recover a money judgment against Landlord, such judgment shall be
satisfied only out of the interest of Landlord in the Premises or mortgage
proceeds therefrom and Landlord shall not be liable for any deficiency. It is
understood and agreed that in no event shall Tenant have any right to levy
execution against any property of Landlord other than its interest in the
Premises as herein before expressly provided. Upon receipt of notice to do so
from any first mortgagee of the Premises, Tenant agrees to give written notice
to such mortgagee in the event of any default hereunder by Landlord. Nothing
herein contained shall

                                       8
<PAGE>

be deemed to in any way limit or restrict Tenant's right to obtain specific
performance or other injunctive or equitable relief with respect to the
performance by Landlord of its covenants herein.

     (b) To the fullest extent permitted by law, Tenant hereby agrees that
Landlord shall not be liable for any claim for damage to person or property,
sustained by Tenant or any person claiming through Tenant resulting from any
accident or occurrence in, about, or upon the Premises unless due to the fault
or negligence of Landlord and Landlord's failure to make such repairs as it is
obligated to make within a reasonable period after notice from Tenant of the
need for such repairs. Said waiver shall include claims for unforeseen acts or
events resulting in damage or injury to person or property sustained by Tenant
or any person claiming through Tenant.

     (c) The sale, conveyance or assignment of the Premises shall operate to
release Landlord from liability, from and after the effective date thereof, upon
all of the covenants, terms and conditions of this Extension of Lease Agreement,
express or implied, except as such may relate to the period prior to such
effective date, and Tenant shall with respect to claims arising thereafter look
solely to Landlord's successor in interest in and to this Extension of Lease
Agreement. This Extension of Lease Agreement shall not be affected by any such
sale, conveyance or assignment, and Tenant shall attorn to Landlord's successor
in interest thereunder.

     (d) Landlord shall not be deemed to be in default of its obligations under
this Extension of Lease Agreement unless Landlord or any mortgagee of which
Tenant has been given notice pursuant to Section 8(e) shall have received notice
thereof and such default shall continue uncured for a period of thirty (30) days
following receipt of such notice. No performance by any such mortgagee of
Landlord's obligations or exercise of its rights, undertaken in a commercially
reasonable manner, shall subject such mortgagee to any liability under this
Extension of Lease Agreement. Landlord and Tenant agree that the covenants to be
performed by each are independent and Tenant shall have no right to offset
against Rental (except as expressly permitted hereunder) or terminate this Lease
in the event of Landlord's failure to perform any of its obligations hereunder.

     15. Casualty to Premises. (a) If, during the term hereof, the Premises
shall be destroyed or so damaged by fire or other casualty as to be unfit, in
whole or in part, for occupancy and such destruction or damage can reasonably be
repaired to substantially the same form and condition and with substantially the
same materials as before such destruction or damage, within nine (9) months
following the date thereof, then Tenant shall not be entitled to surrender
possession of the Premises nor shall Tenant's liability to pay rent under this
Extension of Lease Agreement cease without the mutual consent of the parties
hereto. In the event of any such destruction or injury, Landlord shall repair
the same with all reasonable speed and shall complete such repairs within nine
(9) months from the date of such damage or destruction. If during such period
Tenant shall be deprived of the use of all or any portion of the Premises, a
proportionate allowance shall be made to Tenant from the Rental corresponding to
the time during which and to the portion of the Premises of which Tenant shall
be so deprived.

     (b) If such destruction or injury cannot reasonably be repaired to such
former condition within nine (9) months from the date of such destruction or
damage, Landlord shall notify Tenant within sixty (60) days after the happening
of such destruction or damage whether or not Landlord will repair or rebuild. If
Landlord shall elect to repair or rebuild, Landlord shall specify the time
within which such repairs or reconstruction will be completed, and Tenant shall
have the option,

                                       9
<PAGE>

exercisable within thirty (30) days after the receipt of such notice, to elect
either to terminate this Extension of Lease Agreement and any further liability
hereunder or to extend the term of the Extension of Lease Agreement (at the
rental in effect immediately preceding expiration of the normal term hereof) by
a period of time equivalent to the time from the happening of such destruction
or injury until the Premises are restored to such former condition. In the event
Tenant elects to extend the term of the Extension of Lease Agreement, Landlord
shall restore the Premises to such former condition within the time specified in
such notice, and Tenant shall not be liable to pay Rental for the period from
the time of such destruction or injury until the Premises are so restored to
such former condition.

     (c) In the event that Landlord does not elect to repair or rebuild the
Premises pursuant to paragraph (b) above, then Tenant may at its option,
terminate this Extension of Lease Agreement and any further liability hereunder;
or (ii) continue this Extension of Lease Agreement with the Rental adjusted to
reflect the diminution in the value of the Premises effected by such destruction
or damage, effective as of the date of such destruction or damage after such
reconstruction. If Tenant determines to continue this Extension of Lease
Agreement pursuant to this paragraph (c) then Tenant shall be entitled, at its
cost and expense, to repair or rebuild. Reconstruction shall be at least equal
in quality to the original construction of the building and shall, to the extent
practical, be wholly consistent in design and materials therewith. It shall be
undertaken only in full compliance with law after all permits and approvals have
been obtained. It shall be further undertaken only after plans and
specifications therefor have been approved by Landlord, which approval shall not
be unreasonably withheld or delayed.

     (d) In the event of any such destruction or damage, Tenant shall be
entitled to reduction or abatement of Rental only as provided in this Section
15; Tenant shall not be entitled to any reduction or abatement in Rental
hereunder if any such damage or destruction is caused by an act or omission of
Tenant, its officers, agents, employees or invitees except to the extent that
Landlord shall be insured against same and receive the proceeds of such
insurance. Landlord shall have no liability to Tenant by reason of any injury to
or interference with Tenant's business or property arising from any such
destruction or damage unless caused by an act or omission of Landlord. Landlord
shall in no event be liable for any such injury or interference resulting from
the making of any repairs to the Premises undertaken by Landlord in good faith.

     16. Condemnation. (a) In the event that the entire Premises shall be taken
by condemnation or right of eminent domain, this Extension of Lease Agreement
shall terminate as of the day possession shall be taken by the taking authority,
and Landlord and Tenant shall be released from any further liability hereunder
thereafter accruing.

     (b) In the event that only a portion of the Premises shall be taken by
condemnation or right of eminent domain and the portion so taken renders the
balance unsuitable for the purpose of this Extension of Lease Agreement, the
Tenant may, at its option, elect to terminate this Extension of Lease Agreement
effective as of the day possession shall be taken, provided thirty (30) days
notice of such termination is given. If, in such case, this Extension of Lease
Agreement is not terminated, Landlord may, at its option-restore the Premises
with reasonable speed to an architectural unit as nearly like its condition
prior to such taking as shall be practicable; and if during and/or after the
work of restoration, Tenant is deprived of, the use of all or a part of the
Premises, an appropriate reduction of Rental, depending upon the time during
which and the portion of said Premises of which Tenant is so deprived, shall be
granted. In the event Landlord elects not to so restore the Premises, then
Tenant may at its option; (i) terminate this Extension of

                                       10
<PAGE>

Lease Agreement and any further liability hereunder; or (ii) continue this
Extension of Lease Agreement with the Rental adjusted to appropriately reflect
the diminution in value of the Premises effected by such taking, effective as of
the date thereof. If Tenant elects to continue this Extension of Lease Agreement
then Tenant may, at its own cost and expense, so restore the Premises.

     (c) All damages awarded in connection with the taking of the Premises,
whether allowed as compensation for diminution in value to the leasehold or to
the fee of the Premises, shall belong to the Landlord. Notwithstanding the
foregoing, Tenant shall be entitled to make a separate claim for damage to
merchandise and moveable trade fixtures, and removal reinstallation, and moving
expenses, provided it does not reduce the award payable to Landlord.

     17. Default. (a) If: (i) there shall be a default in payment of any Rental
which shall continue for a period of ten (10) days following receipt by Tenant
of notice thereof from Landlord; or (ii) there shall be a default in any other
of Tenant's obligations hereunder or if the Premises be abandoned or vacated by
Tenant; and if such default or condition shall continue for a period of thirty
(30) days following receipt by Tenant of notice from Landlord to make good such
default or correct such condition; or (iii) any proceedings under the present or
any future Bankruptcy Act be instituted by or against Tenant, or any receiver or
trustee be appointed for or ordered to dispose of Tenant's business or property,
or if Tenant makes any assignment or conveyance for benefit of creditors and if
any such proceeding instituted against Tenant shall not be dismissed within 20
days following the date of such institution; then, in such event Landlord shall
have the right, immediately or at any time thereafter, to enter upon the
Premises in the name of the whole and repossess the same as of its former estate
and expel Tenant and all those claiming by, through or under it, and remove
their goods and effects and store the same on behalf of Tenant without being
deemed guilty of any manner of trespass and without prejudice to any remedies
which might otherwise be used for arrears of rent or other default hereunder and
upon entry as aforesaid this Extension of Lease Agreement shall be terminated.
Landlord, at its election, may effect such termination by written notice to
Tenant to that effect, which shall have the same force as an entry for breach as
provided in this Section. In case of such termination, Landlord shall become
entitled to receive from Tenant, and Tenant shall pay to Landlord on demand, as
initial liquidated damages, a sum equal to the amount by which the sum of the
rent and other payments called for hereunder for the remainder of the term
exceeds the fair rental value of he Premises for the remainder of the term.
Further, Tenant shall, on demand of Landlord, from time to time indemnify
Landlord against all loss of rent, other payments and damages, however caused,
which it may incur by reason of such termination during the remainder of the
term, first giving credit to any payments made by Tenant to Landlord on account
of initial liquidated damages as aforesaid. In computing such damages there
shall be added such reasonable expenses as Landlord may incur in connection with
such termination and/or reletting, such as legal expenses, brokerage, expenses
for keeping the Premises in good order and for preparing the same for reletting
and expenses and/or decorations in the Premises as way be necessary for the
purpose of reletting. Landlord shall also have the right to pursue such other
rights and remedies as may be allowed at law or equity against Tenant, and any
and all other parties who may be liable. All such remedies shall be cumulative.
Provided, however, if any such default be under clause (ii) above and it would
take more than thirty (30) days to cure the same, Landlord shall not forfeit the
lease created hereby, enter upon the Premises or exercise any of the other
remedies herein provided for such default if Tenant begins the cure thereof
within such period and pursues same with reasonable due diligence to completion.

     (b) Intentionally Omitted.

                                       11
<PAGE>

     (c) Intentionally Omitted.

     18. Quiet Enjoyment. The Landlord covenants and agrees with Tenant that as
long as the Tenant keeps and performs all of the covenants and conditions to be
performed by Tenant hereunder, during the term of this Extension of Lease
Agreement Tenant shall have quiet and undisturbed and continued possession of
the Premises, free from any claims against the Landlord and all persons claiming
under, by or through the Landlord.

     19. Intentionally Omitted.

     20. Intentionally Omitted.

     21. Intentionally Omitted.

     22. Intentionally Omitted.

     23. Arbitration. If any controversy shall arise relating to the provisions
of this Extension of Lease Agreement or the tenancy or other rights created
hereby, and such dispute shall not be resolved by the parties within fifteen
(15) days after either party shall notify the other in writing of its desire to
arbitrate the dispute, then the dispute shall be settled by arbitration. Such
arbitration shall be conducted at Boston, Massachusetts, under the rules then
obtaining of the American Arbitration Association. There shall be a board of
three arbitrators, one appointed by the Landlord, one appointed by Tenant and a
third selected by the two so named. The arbitrators shall have no power to add
to, subtract from or modify any of the terms or conditions of this Extension of
Lease Agreement. The award of the arbitrators shall be final and binding and
conclusive on the parties, provided, however, that nothing herein contained
shall limit Tenant's right to exercise the rights referred to in the last
sentence of Section 14(a) hereof.

     24. General Provisions. (a) Words of any gender used herein shall be
construed to include any other gender, and words in the singular number shall be

of and be binding upon the parties hereto and their respective successors,
permitted assigns and legal representatives; (c) the headings used herein are

Agreement shall be held to be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions of this Extension of
Lease Agreement shall not in any way be affected or impaired thereby; (g) this
Extension of Lease Agreement shall be governed by and construed in accordance
with the laws of the Commonwealth of Massachusetts; (h) each of the parties

indemnify and hold the other harmless from and against any claims, liabilities
or losses (including attorney's fees) arising out of a breach of this warranty;
(i) Landlord and Tenant shall each have the right to contest in good faith

                                       12
<PAGE>

the validity or amount of any tax, assessment, license fee, excise fee and other
charge for which it is responsible under this Extension of Lease Agreement
provided that no contest by Tenant may be undertaken unless Tenant shall, upon
Landlord's request, deposit with Landlord adequate and sufficient security
against any loss or damage which may ensue or involve the reasonable possibility
of forfeiture, sale or disturbance of Landlord's interest in the Premises and
that upon the final determination of any contest by Tenant, Tenant shall
immediately pay and satisfy the amount found to be due, together with any costs,
penalties and interest; (j) In any case where either party hereto is required to
do any act, other than the making of any payment of Rental, the time for
performance thereof shall be extended for a period equal to any delay caused by
or resulting from any act of God, war, civil commotion, fire, casualty, labor
difficulties, shortages of labor, materials or equipment, governmental
regulations or other causes beyond such party's reasonable control, the extent
that the performance of such obligation was actually prevented thereby; (k) This
instrument constitutes the entire agreement between the parties relating to the
subject matter hereof and supercedes all prior negotiations, contracts or
understandings; Tenant acknowledges that except for the Specifications and the
provisions of Section 8 hereof, it has not been induced to enter into this
Extension of Lease Agreement based on any representations made by Landlord.

     25. Allocations. (a) Except as provided below, all expenses and costs
incurred by Tenant in performing its obligations under this Extension of Lease
Agreement shall remain the expense of Tenant, including, without limitation, all
expenses and costs related to the maintenance, repair and replacement of the
Premises and the systems and services exclusively serving the same.

     (b)Real Estate Taxes, Utility Costs (which are not separately metered to
the Premises) shall be allocated between Landlord and Tenant based upon the
percentage which square footage of the Premises bears to the square footage of
the Building (and excluding common areas of the Building) (the "Tenant's Share")
and the remainder share be "Landlord's Share", except that as to Utility Costs,
Landlord and Tenant agree to use reasonable good faith efforts to agree on an
alternative method of sharing such costs to the extent the same vary based on
level of occupancy, use or intensity of use by the occupants of the Building,
including Tenant. Such alternative method of sharing such Utility Costs shall
take into account areas within the Premises and Building which are separately
metered. As of the date hereof, it is agreed Tenant's Share is 53.41% and
Landlord's Share is 46.59%.

     (c)Landlord shall pay Landlord's Share of Insurance Costs to the extent
related to insurance required under Section 7(c) above.

     (d) Landlord shall pay Landlord's Share of the Operations Costs to the
extent related to, or benefiting areas of, the Building and the Real Estate
other than the Premises such as heating and ventilation of common area and
external maintenance cost such as grounds keeping, snow plowing and security
costs.

     (e) In addition to Landlord's obligation to pay Landlord's Share as set
forth herein, Operating Costs shall not include and Landlord shall be solely
responsible for the payment of: (1) leasehold improvements, alterations and
decorations which are made in connection with the preparation of any portion of
the Building for occupancy by a new tenant, or which improvements, alterations
and decorations are not generally beneficial to all tenants of the Building; (2)
costs incurred in connection with the making of repairs or replacements which
are the obligation of another tenant or occupant of the Building; (3)
advertising, marketing, promotional, public relations or brokerage fees,
commissions or expenditures; (4) financing and refinancing costs

                                       13
<PAGE>

in respect of any mortgage or security interest placed upon the Real Estate or
any portion thereof, including payments of principal, interest, finance or other
charges, and any points and commissions in connection therewith; (5) costs
(including, without limitation, attorneys' fees and disbursements) incurred in
connection with any judgment, settlement or arbitration award resulting from any
tort liability; (6) costs of any item which are reimbursed to Landlord by other
tenants or third parties or which are properly chargeable or attributable to a
particular tenant or particular tenants; (7) costs incurred in connection with
Landlord's preparation, negotiation, dispute resolution and/or enforcement of
leases, including court costs and attorneys' fees and disbursements in
connection with any summary proceeding to dispossess any tenant or incurred in
connection with disputes with prospective tenants, employees, consultants,
management agents, leasing agents, purchasers or mortgagees; (8) costs of any
additions to or expansions of the Real Estate or the Building; (9) any costs in
the nature of fees, fines or penalties arising out of Landlord's breach of any
obligation (contractual or at law, and including, without limitation, costs,
fines, interest, penalties and costs of litigation incurred as a result of late
payment of taxes and/or utility bills), including attorneys' fees related
thereto("Direct Landlord Costs").

     (f) Notwithstanding any provision of this Lease to the contrary, Landlord
shall have the right if Landlord leases space in the Building to another tenant,
upon notice to Tenant, to undertake the (i) maintenance and repair obligations
of Tenant as to the Building and the Real Estate (exclusive of the Premises and
the systems exclusively serving the Premises), (ii) payment of Real Estate
Taxes, (iii) payment of Utility Costs (which are not separately metered to the
Premises), and (iv) placement of insurance on the Building as required of Tenant
under Section 7(c) above, and from and after the date of such election, Tenant
shall, within 30 days of Landlord's request, pay Tenant's Share of such amounts.
In the event the Building becomes a multi-tenant building, Tenant's right to
parking spaces, use of internal and external common space and the allocation of
utility services in the event of a limitation or rationing of availability
thereof to the Premises shall likewise be allocated based upon Tenant's Share.

     (g) All allocations under this Lease Agreement based upon Tenant's share
allocable to the Premises shall be allocable on the basis of the percentage
derived from a ratio having as its denominator 144,230 and as its numerator the
number of feet of space occupied by Tenant from time to time or dedicated to
serving such space; 77,037 as of the Commencement Date. In the event that any
portion of the interior or exterior common space is dedicated exclusively to the
use of one of the parties, that party shall bear all expenses and costs with
respect thereto.

     26. Relocation. In the event Landlord has executed a written lease with
another tenant for space within the Building located in the area shown on
Exhibit A as the "Reserved Space" and, in Landlord's reasonable judgment, the
use and enjoyment of such tenant's premises requires the Tenant to vacate any
portion of the Reserved Space currently occupied by Tenant or the relocation of
another portion of the Premises to create common areas typical of a multi-tenant
building (not to exceed 10% of the total square footage then occupied by Tenant)
so used by Tenant, Tenant hereby agrees to vacate such space on 30 days notice
provided Landlord agrees to provide other space within the Building of equal or
greater size, comparable or superior quality.
