--------------------------------------------------------------------------------

4. Annual Fixed Rent. Effective as of the Extension Commencement Date, the
definitions of “Annual fixed Rent” in Section 1.1 of the Original Lease and
Section 3 of the First Amendment shall be deleted in their entirety and replaced
with the following:

 

Extended Lease Year

   Rent Per
Rentable
Square
Foot    Annual Fixed
Rent    Monthly Rent

1-3

   $ 24.25    $ 2,750,750.25    $ 229,229.19

4-5

   $ 25.25    $ 2,864,183.25    $ 238,681.94

6-10

   $ 28.25    $ 3,204,482.25    $ 267,040.19

11-12

   $ 31.25    $ 3,544,781.25    $ 295,398.44

Annual Fixed Rent shall be due and payable in equal monthly installments as
provided in Section 2.5 of the Lease.

5. Extension Options. Section 2.4.1 of the Lease is hereby deleted in its
entirety and replaced with the following:

Tenant shall have the option to extend the Term for two (2) additional 5 year
extension terms (each an “Extension Term”) by notice given to Landlord at least
one (1) year before the Term Expiration Date. Tenant’s election shall be
exercised, and Annual Fixed Rent for the Extension Term determined, as set forth
below. If Tenant fails timely to exercise its option for any Extension Term,
Tenant shall have no further extension rights hereunder.

Tenant’s option so to extend the Term shall be void, at Landlord’s election, if
Tenant is in default at the time Tenant elects to extend the Term or at the time
the Term would expire but for such extension or if more than seventy percent
(70%) of the Premises are to be used as a data center during such Extension
Term. Tenant shall have no right to extend the Term for less than seventy
percent (70%) of the Premises. During the Extension Term, if any, all provisions
of this Lease shall apply except that Tenant shall have no further option to
extend the Term after the last Extension Tenn.

During the Extension Term, Tenant shall pay Annual Fixed Rent equal to the
greater of (i) the Annual Fixed Rent then being paid under the Lease or
(ii) ninety five percent (95%) of the then prevailing market rate for a five
(5) year lease of office space in the Greater Boston, Massachusetts
“Metro-North” area comparable to the Premises in terms of location within a
building, finish, age, building quality and amenities for a tenant of equal size
and financial strength as Tenant, under terms and conditions substantially the.
same as those of this Lease as though then available for single occupancy for
the Permitted Uses (or any higher and better use then being made by Tenant) in
“as-is” condition or such better condition in which Tenant is required to
maintain the Premises taking into account rent abatements, construction costs
and other concessions and the manner, if any, in which Landlord is reimbursed
for operating expenses and taxes (the “Fair Market Rent”).

Landlord shall notify Tenant of its estimate of the Fair Market Rent within ten
(10) days after Tenant exercises the applicable extension option. Tenant shall
have the option to accept or

--------------------------------------------------------------------------------

reject by written notice Landlord’s estimate, or to withdraw its exercise of the
extension option, in any case within fourteen (14) days following delivery of
Landlord’s estimate. Tenant’s failure to respond within such period shall be
deemed to constitute acceptance of Landlord’s estimate. In the event Tenant
rejects Landlord’s estimate then the Fair Market Rent shall be arbitrated in
accordance with the following procedure.

Each of Landlord and Tenant, within twenty (20) days after notice by Tenant
disputing Landlord’s estimate of the Fair Market Rate, shall appoint as an
arbitrator an MAI appraiser with at least ten (10) years experience as an
appraiser of office buildings in the Greater Boston area, including first class
suburban office buildings, and shall give notice of such appointment to the
other party. If either Landlord or Tenant shall fail timely to appoint an
arbitrator, the other may apply to the Boston office of the American Arbitration
Association (“AAA “) for appointment of such an arbitrator five (5) Business
Days, as such term is defined in Section 8.19, after notice of such failure to
the delinquent party if such arbitrator has not then been appointed. The two
arbitrators shall, within five (5) Business Days after appointment of the second
arbitrator, appoint a third arbitrator who shall be similarly qualified. If the
two arbitrators are unable to agree timely on the selection of the third
arbitrator, then either arbitrator on behalf of both may request such
appointment from the Boston office of the AAA. The arbitration shall be
conducted in accordance with the commercial arbitration rules of the AAA insofar
as such rules are not inconsistent with the provisions of this Lease (in which
case the provisions of this Lease shall govern). The arbitrators shall be
charged to reach a majority written decision in accordance with the standards
for the Fair Market Rate as provided in this Section 2.4.1, within twenty
(20) days after the third arbitrator is appointed, by selecting either of the
final estimates of the Fair Market Rate provided by Landlord and Tenant at the
commencement of the hearing. The arbitrators shall have no authority or
jurisdiction to make any other determination of such amount. The cost of the
arbitration (exclusive of each party’s witness and attorneys fees, which shall
be paid by such party) shall be borne equally by the parties. If the AAA shall
cease to provide arbitration for commercial disputes in Boston, the second or
third arbitrator, as the case may be, shall be appointed by any successor
organization providing substantially the same services, and in the absence of
such an organization, by a court of competent jurisdiction under the arbitration
act of The Commonwealth of Massachusetts.

If Landlord should delay in giving the notice which begins the valuation
procedures of this Section 2.4.1, or if the process should otherwise be delayed
for any reason, then such procedures shall nevertheless remain in effect and be
applicable when and as invoked with respect to Annual Fixed Rent payable during
the Extension Term; but until such procedures are completed, Tenant shall pay on
account of Annual Fixed Rent at the rate established for Annual Fixed Rent for
the last twelve (12) months of the Term (and upon Fair Market Rent being
established, Tenant shall pay the same within ten (10) days of such
determination, retroactively to the beginning of the Extension Term). Each party
shall bear the costs of the arbitrator selected by it and shall share equally in
the costs of the third arbitrator selected in accordance herewith. The parties
shall adjust for over or under payments within twenty (20) days after the
decision of the arbitrators is announced.

--------------------------------------------------------------------------------

Promptly after the Annual Fixed Rent is determined for each Extension Term,
Landlord and Tenant shall enter into an amendment of this Lease confirming the
extension of the Term and the new rate for Annual Fixed Rent.

6. Expansion. (a) Right of First Offer. Simultaneously with any offer to lease
any portion of the Building or any portion of the building located at 70 I
Edgewater Drive, Wakefield, Massachusetts (the “701 Building,” and collectively
with the Building, the “ROFO Space”), to any third party, Landlord shall offer
to lease such space to Tenant at the Second Amendment Expansion Market Rent
(defined below), except as provided below, provided however, that (a) if there
are less than three (3) Lease Years left in the Term at the time Landlord is
offering to lease any such ROFO Space, unless Tenant leases five thousand
(5,000) square feet or less of such ROFO Space, Tenant may lease such ROFO Space
only if Tenant has irrevocably exercised the Extension Option set forth in
Section 2.4.1 of the Lease (as amended by Section 5 hereof) for the Premises so
that such ROFO Space shall be leased by Tenant for more than a three (3) year
term, (b) such ROFO Space shall be leased by Tenant in its “as is” condition
with such tenant improvement allowances, free rent, or other concessions as are
then being offered generally for comparable space in comparable properties in
the “greater Metro-North” area, (c) the figures for Base Operating Expenses and
Base Taxes applicable to such ROFO Space shall be the actual amounts (adjusted
to 95% occupancy) for the calendar year and fiscal year, respectively, in which
such ROFO Space is to be delivered to Tenant, and (d) Tenant may elect to lease
either a portion of, or at Tenant’s option, the entire ROFO Space to the extent
that the same is not then under lease to other tenants or the subject of active
lease negotiations following an offer to Tenant under this Section 6(a) (the
“ROFO Option”). Any tenant or occupant of the ROFO Space from time to time, any
affiliate thereof, or any party having a right (including right of first offer)
as of the date hereof to lease such space, including without limitation,
Metcalf & Eddy, to the extent of its rights to lease a portion of such space as
of the date hereof, shall not be considered a “third-party” for purposes of this
Section 6(a), and Landlord shall be free to lease any portion of the ROFO Space
to any of the foregoing without offering the same to Tenant. Notwithstanding the
foregoing, if Landlord’s offer to Tenant hereunder occurs at any time from and
after the first day of the Extension Commencement Date through the last day of
the twenty-fourth (24th) month following the Extension Commencement Date,
Landlord shall offer to lease such space to Tenant on the same terms and
conditions as contained in the Lease on a pro rata basis.

Any offer by Landlord under this Section 6(a) may be accepted by Tenant by
written notice given within twenty (20) days of delivery of Landlord’s offer. If
Tenant does not timely accept Landlord’s offer, then Tenant’s rights under this
Section 6(a) shall be deemed conclusively waived by Tenant with respect to the
next lease of such ROFO Space, provided that (i) the next such lease’ of such
ROFO Space is entered into within six (6) months after Tenant’s failure to
accept Landlord’s offer and (ii) the difference between the net present value of
the economic terms of the next such lease and the net present value of the
economic terms of the Landlord’s offer is less than ten percent (10%) of the net
present value of the economic terms of Landlord’s offer. Landlord shall have no
further obligation to offer such ROFO Space to Tenant before next leasing the
same to a third party occurring within such six (6) month period and on such
economic terms, but this Section 6(a) shall apply to any other lease of ROFO
Space. In the event that Tenant accepts any offer by Landlord under this
section, the leasing of such Second Amendment Offered Space and the rent
therefor shall be documented by an amendment to the

--------------------------------------------------------------------------------

Lease. Tenant’s rights under this Section 6 shall be rendered void, at
Landlord’s election, if Tenant is in default beyond any applicable notice or
grace period at the time Landlord offers any space to a third party or at the
time Tenant’s lease of any Second Amendment Offered Space under this Section 6
would otherwise commence. For purposes of this paragraph, net present value
shall be calculated using an eight percent (8%) discount rate.

If Tenant exercises its rights under this Section 6(a), Landlord shall use
reasonable efforts to deliver the ROFO Space as set forth in Landlord’s offer.
Landlord’s failure to deliver, or delay in delivering, all or any part of the
ROFO Space by reason of Force Majeure, as such term is defined in Section 4.2 of
the Lease, and including continued occupancy of any such ROFO Space by any
occupant thereof shall not give rise to any liability of Landlord, shall not
alter Tenant’s obligation to accept such ROFO Space when delivered, shall not
constitute a default of Landlord, and shall not affect the validity of the
Lease, as amended hereby; provided that if delivery of the ROFO Space does not
occur within ninety (90) days after the delivery date set forth in Landlord’s
Offer, Tenant may elect to withdraw its exercise of its rights under this
Section 6(a) by notice given within five (5) Business Days after the expiration
of such ninety (90) day period. If Tenant so notifies Landlord, Tenant’s Right
of First Offer under this Section 6(a) shall not apply to the next lease of the
ROFO Space in question (but shall apply to subsequent leases thereafter).

The terms of this Section 6(a) are intended to supersede the terms of Section 5
of the First Amendment, and Section 5 of the First Amendment is hereby deleted
in its entirety.

(b) Expansion Option. Tenant shall have the option (“Tenant’s Expansion Option”)
to expand the Premises in accordance with the provisions of this Section 6(b) to
include all remaining space in the Building (approximately 37,147 square feet of
Rentable Floor Area) (the “Expansion Area”). Tenant’s Expansion Option may be
exercised by Tenant by written notice to Landlord (“Tenant’s Expansion Notice”)
given at any time, provided, however, that if there are less than three
(3) Lease Years left in the Term at the time Landlord is offering to lease any
such Expansion Space, unless Tenant leases five thousand (5,000) square feet or
less of such Expansion Area, Tenant may lease such Expansion Space only if
Tenant has irrevocably exercised the Extension Option set forth in Section 2.4.1
of the Lease (as amended by Section 5 hereof) for the Premises so that such
Expansion Space shall be leased by Tenant for more than a three (3) year term.
The “Estimated Expansion Date” shall be the date four (4) months following the
date of Tenant’s Expansion Notice. Annual Fixed Rent for the Expansion Area
shall be paid in accordance with the terms and conditions of Section 2.5 of the
Lease at an Annual Fixed Rent rate equal to the Second Amendment Expansion
Market Rent with respect to the Expansion Area, except as provided below. Upon
receipt of Tenant’s Expansion Notice, but subject to any existing leases for
space in the Building as of the Extension Commencement Date, Landlord shall use
its best efforts to relocate any existing tenant located in the Tenant’s
Expansion Area to make space available for Tenant to exercise its Expansion
Option. In the event that the Premises are expanded in accordance with
Section 6(b) hereof, the leasing of the corresponding Expansion Area shall be
documented by an amendment to the Lease specifying the area and location of the
Premises as expanded, the Annual Fixed Rent rate applicable to such Expansion
Area, and the estimated date the Premises are to be expanded hereunder with a
provision for establishing the effective date of such expansion based upon
actual delivery of such Expansion Area to Tenant

--------------------------------------------------------------------------------

pursuant to the following paragraph. Notwithstanding the foregoing, if Tenant
exercises Tenant’s Expansion Option at any time from and after the first day of
the Extension Commencement Date through the last day of the twenty-fourth
(24th) month following the Extension Commencement Date, Annual Fixed Rent shall
be paid at a rate equal to the rate contained in the Lease on a pro rata basis.

If Tenant’s Expansion Option is validly exercised, Landlord shall endeavor in
good faith to deliver the Expansion Area on or about the Estimated Expansion
Date. If the Expansion Area is not delivered within four (4) months following
Tenant’s Expansion Notice (unless such delay is due to the act or omission of
Tenant), Tenant shall have no obligation to accept the Expansion Area, and
Tenant’s Expansion Option may be deemed rescinded at Tenant’s option by thirty
(30) days advance written notice given by Tenant (unless Landlord shall have
delivered the Expansion Area within such thirty (30) day period). Each Expansion
Area shall be delivered to Tenant pursuant to the provisions of Article III of
the Lease except that Tenant and Landlord obligations thereunder shall apply to
such Expansion Area only, the Premises shall be such Expansion Area, the
Tenant’s Plans Delivery Deadline shall be thirty (30) days following Landlord’s
receipt of Tenant’s Expansion Notice, the Term Commencement Date shall be the
Estimated Expansion Date, and Landlord shall provide Tenant with an allowance
for the Premises Improvements in an amount not to exceed the per rentable square
foot allowance provided for the original Premises multiplied by the number of
months remaining in the Term at the Estimated Expansion Date, and divided by the
number of months in the Term. Landlord’s failure to deliver, or delay in
delivering, all or any part of the Expansion Area on the Estimated Expansion
Date, as applicable, for any reason, shall not give rise to any liability of
Landlord, shall not alter Tenant’s obligation to accept such space when
delivered, shall not constitute a default of Landlord, and shall not affect the
validity of the Lease, as amended hereby; provided that Tenant shall have the
rescission right as stated in the second sentence of this paragraph,
notwithstanding any provisions of Article III of the Lease to the contrary.

Landlord covenants that it will not enter into any lease for the Building or the
701 Building containing the right of a tenant thereunder to expand its leased
pren1ises into the Expansion Area unless Tenant’s Expansion Option has expired
or has been waived by Tenant. Landlord shall not grant, at any time, for both
the Building and the 701 Building additional extension options for other tenants
located in those buildings. If a tenant in the Building or the 701 Building
fails to timely and properly respond to any notice by Landlord with respect to
extending its lease, such space shall be made available to Tenant in accordance
with the terms of Section 6(a) hereof within six (6) Business Days of the
expiration of such tenant’s extension rights under such tenant’s lease.

(c) “Second Amendment Expansion Market Rent” shall mean the then prevailing
market rate for a five (5) year lease of office space in the “greater
Metro-North” area comparable to the applicable New Space (defined below) in
terms of location within a building, finish, age, building quality and amenities
for a tenant of equal size and financial strength as Tenant, under terms and
conditions substantially the same as those on which Tenant shall have the right
to lease the applicable New Space. If Landlord and Tenant have not agreed, in
writing, on the Second Amendment Expansion Market Rent for the applicable New
Space within fourteen (14) days after Tenant accepts Landlord’s offer, then at
the request of either party Second Amendment

--------------------------------------------------------------------------------

Expansion Market Rent for the applicable New Space shall be. Determined in
accordance with the arbitration procedure set forth in Section 2.4.1 of the
Lease (as amended by Section 5 hereof) for the determination of Fair Market
Rent.

(d) Except as set forth herein~ any lease by Tenant of the ROFO Space and the
Expansion Area (collectively, the “New Space”) shall be on all of the terms and
conditions in effect for the Premises immediately prior to such expansion. If
Tenant timely exercises Tenant’s Expansion Option or Tenant’s ROFO Option, the
applicable New Space shall be added to the Premises for the remainder of the
Term .effective as of the date on which such New Space is delivered to Tenant.

(e) Notwithstanding any provision of this Section 6 to the contrary, Tenant’s
Expansion Option and/or ROFO Option shall be void, at Landlord’s election, if
(i) Tenant is in default hereunder at the time Tenant elects to exercise
Tenant’s Expansion Option, if Tenant is in default when Landlord offers any ROFO
Space to any third party, or at the time the New Space would be added to the
Premises, (ii) Tenant has made any Transfer under Section 5.9 of the Lease
unless such Transfer is to a Transferee which has a creditworthiness at least
equal to the net worth of Tenant as of the date of such Transfer, or
(iii) Tenant is not occupying the Premises.

(f) Nothing in this Section 6 shall be construed to grant to Tenant any rights
or interest in any space in the Building or the 701 Building, and any claims by
Tenant alleging a failure of Landlord to comply herewith shall be limited to
claims for monetary damages. Tenant may not assert any rights in any space nor
file any lis pendens or similar notice with respect thereto.

7. Assignment and Subletting. Section 5.9 of the Lease is hereby amended by
inserting the following at the end of said Section 5.9: “Notwithstanding
anything to the contrary contained herein, Tenant shall have the right, without
prior approval of Landlord, to utilize such portions of the Premises as it shall
determine in its sole, reasonable judgment to customers (“Collocation”) at no
additional rent to Tenant for the purpose of installing, operating and
maintaining computer servers and related equipment. The Collocation will not be
considered a sublease for purposes hereunder. Subject to Section 5.4 of the
Lease, designated employees or such customers may have access to the Premises 24
hours per day, seven days per week.”

8. Parking. In the event Tenant expands the Premises in accordance with
Section 6 of this Second Amendment, upon delivery of such expansion space,
Landlord agrees to provide four (4.0) parking spaces per 1,000 square feet of
such expansion space on a non-reserved basis in the Automobile Parking Area
during the Extended Term of the Lease on the same terms and conditions for
parking spaces set forth in Section 11.1 of the Lease.

9. Miscellaneous.

(a) Section 2.6 of the Lease shall be amended by replacing the terms “2003”,
“2004” and “2007” with the terms “2008”, “2009” and “2012”, respectively.

reasonable period” in the penultimate sentence of the first paragraph thereto
and replacing it with the phrase “over such item’s useful life”.

(c) Section 2.6.6 of the Lease shall be amended by deleting the phrase “shall
have the right to have an independent certified public accountant (an

have the right to have (i) an independent certified public accountant or (ii) a
firm mutually acceptable 10 Landlord and Tenant (provided that such firm is not

dealings with any broker or agent in connection with this Second Amendment,
except DTZFHO Partners and Wyman Street Advisors. Each such party covenants to
defend (by counsel of the other party’s choice), pay, hold harmless and

expense or liability for any compensation, commissions, and charges claimed by
any broker or agent, with respect to this Second Amendment or the negotiation
