Re: Warrants

The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and
conditions of the Warrants issued by Exterran Holdings, Inc. (“Company”) to Credit Suisse
International (“Dealer”), represented by Credit Suisse, New York branch (“Agent”) as its agent, as
of the Trade Date specified below (the “Transaction”). This letter agreement constitutes a
“Confirmation” as referred to in the ISDA Master Agreement specified below. This Confirmation
shall replace any previous agreements and serve as the final documentation for this Transaction.

The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the
“Equity Definitions”), as published by the International Swaps and Derivatives Association, Inc.
(“ISDA”), are incorporated into this Confirmation. In the event of any inconsistency between the
Equity Definitions and this Confirmation, this Confirmation shall govern. This Transaction shall
be deemed to be a Share Option Transaction within the meaning set forth in the Equity Definitions.

Each party is hereby advised, and each such party acknowledges, that the other party has
engaged in, or refrained from engaging in, substantial financial transactions and has taken other
material actions in reliance upon the parties’ entry into the Transaction to which this
Confirmation relates on the terms and conditions set forth below.

1. This Confirmation evidences a complete and binding agreement between Dealer and Company as to
the terms of the Transaction to which this Confirmation relates. This Confirmation shall
supplement, form a part of, and be subject to an agreement in the form of the 2002 ISDA Master
Agreement (the “Agreement”) as if Dealer and Company had executed an agreement in such form (but
without any Schedule except for the election of the laws of the State of New York as the governing
law (without reference to choice of law doctrine)) on the Trade Date. In the event of any
inconsistency between provisions of that Agreement and this Confirmation, this Confirmation will
prevail for the purpose of the Transaction to which this Confirmation relates. The parties hereby
agree that no Transaction other than the Transaction to which this Confirmation relates shall be
governed by the Agreement.

	First Expiration Date:

expired or been exercised as of such day, divided by the remaining number of Expiration
Dates (including such day), rounded down to the nearest whole number, subject to

	 	Section 6.3(a)(ii) of the Equity Definitions is hereby amended by
replacing clause (ii) in its entirety with “(ii) an Exchange Disruption, or” and

the Share Delivery Quantity of Shares for such Settlement Date to the account specified
hereto free of payment through the Clearance System.
	 
	 	 
	Share Delivery Quantity:

	 	For any Settlement Date, a number of Shares, as calculated by
the Calculation Agent, equal to the Net Share Settlement Amount for such Settlement Date
divided by the Settlement Price on the Valuation Date in respect of such Settlement Date,
rounded down to the nearest whole number plus any Fractional Share Amount;
provided that the Share Delivery Quantity for any
Settlement Date shall not exceed the Maximum Number of
Shares as of such Settlement Date.

 

3

 

	 	 	 
	Net Share Settlement Amount:

	 	For any Settlement Date, an amount equal to the product of
(i) the Number of Warrants exercised or deemed exercised on the relevant Exercise Date,
(ii) the Strike Price Differential for such Settlement Date and (iii) the Warrant
Entitlement.
	 
	 	 
	Settlement Price:

	 	For any Valuation Date, the per Share volume-weighted average price as
displayed under the heading “Bloomberg VWAP” on Bloomberg page EXH.N <equity> AQR
(or any successor thereto) in respect of the period from the scheduled opening time of
the Exchange to the Scheduled Closing Time on such Valuation Date (or if such
volume-weighted average price is unavailable, the market value of one Share on such
Valuation Date, as determined by the Calculation Agent). Notwithstanding the foregoing,
if (i) any Expiration Date is a Disrupted Day and (ii) the Calculation Agent determines
that such Expiration Date shall be an Expiration Date for fewer than the Daily Number of
Warrants, as described above, then the Settlement Price for the relevant Valuation Date
shall be the volume-weighted average price per Share on such Valuation Date on the
Exchange, as determined by the Calculation Agent based on such sources as it deems
appropriate using a volume-weighted methodology, for the portion of such Valuation Date
for which the Calculation Agent determines there is no Market Disruption Event.
	 
	 	 
	Settlement Date(s):

	 	As determined in reference to Section 9.4 of the Equity Definitions,

the Equity Definitions will be applicable, except that all references in such provisions to
“Physically-settled” shall be read as references to “Net Share Settled.” “Net Share Settled”
in relation to any Warrant means that Net Share Settlement is applicable to that Warrant.
	 
	 	 
	Representation and Agreement:

	 	Notwithstanding Section 9.11 of the Equity Definitions, the parties
acknowledge that any Shares delivered to Dealer may be, upon delivery, subject to restrictions
and limitations arising from Company’s status as issuer of the Shares under applicable
securities laws.
	 
	 	 
	3. Additional Terms applicable to the Transaction:

any, to any one or more of the Strike Price, the Number of Warrants, the Daily Number of
Warrants and the Warrant Entitlement. Notwithstanding the foregoing, any cash dividends or
distributions on the Shares, whether or not extraordinary, shall be
governed by Section 9(f) of this Confirmation in lieu of
Article 10 or Section 11.2(c) of the Equity Definitions.

Each of the representations and warranties of Company set forth in Section 3 of the Underwriting
Agreement (the “Underwriting Agreement”) dated as of June 4, 2009 between Company and J.P. Morgan
Securities Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Wachovia Capital Markets, LLC
and Credit Suisse Securities (USA) LLC as representative of the Underwriters party thereto (the

represents and warrants to Dealer that:

	 	(a)	 	Company has all necessary corporate power and authority to execute, deliver and
perform its obligations in respect of this Transaction; such execution, delivery and
performance have been duly authorized by all necessary corporate action on Company’s
part; and this Confirmation has been duly and validly executed and delivered by Company
and constitutes its valid and binding obligation, enforceable against Company in
accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and
remedies generally, and subject, as to enforceability, to general principles of equity,
including principles of commercial reasonableness, good faith and fair dealing
(regardless of whether enforcement is sought in a proceeding at law or in equity) and
except that rights to indemnification and contribution hereunder may be limited by
federal or state securities laws or public policy relating thereto.

	 
	 	(b)	 	Neither the execution and delivery of this Confirmation nor the incurrence or
performance of obligations of Company hereunder will conflict with or result in a
breach of the certificate of incorporation or by-laws (or any equivalent documents) of
Company, or any applicable law or regulation, or any order, writ, injunction or decree
of any court or governmental authority or agency, or any agreement or instrument to
which Company or any of its subsidiaries is a party or by which Company or any of its
subsidiaries is bound or to which Company or any of its subsidiaries is subject, or
constitute a default under, or result in the creation of any lien under, any such
agreement or instrument.

	 
	 	(c)	 	No consent, approval, authorization, or order of, or filing with, any
governmental agency or body or any court is required in connection with the execution,
delivery or performance by Company of this Confirmation, except such as have been
obtained or made and such as may be required under the Securities Act of 1933, as
amended (the “Securities Act”) or state securities laws.

	 
	 	(d)	 	The Shares of Company initially issuable upon exercise of the Warrant by the
net share settlement method (the “Warrant Shares”) have been reserved for issuance by
all required corporate action of Company. The Warrant Shares have been duly authorized
and, when delivered against payment therefor (which may include Net Share Settlement in
lieu of cash) and otherwise as contemplated by the terms of the Warrant following the
exercise of the Warrant in accordance with the terms and conditions of the Warrant,
will be validly issued, fully-paid and non-assessable, and the issuance of the Warrant
Shares will not be subject to any preemptive or similar rights.

	 
	 	(e)	 	Company is not and will not be required to register as an “investment company”
as such term is defined in the Investment Company Act of 1940, as amended.

	 
	 	(f)	 	Company is an “eligible contract participant” (as such term is defined in
Section 1a(12) of the Commodity Exchange Act, as amended (the “CEA”)) because one or
more of the following is true:

	 
	 	 	 	Company is a corporation, partnership, proprietorship, organization, trust or other
entity and:

	 	(A)	 	Company has total assets in excess of USD 10,000,000;

otherwise supported by a letter of credit or keepwell, support or other
agreement, by an entity of the type described in Section 1a(12)(A)(i) through
(iv), 1a(12)(A)(v)(I), 1a(12)(A)(vii) or 1a(12)(C) of the CEA; or

	 
	 	(C)	 	Company has a net worth in excess of USD 1,000,000 and has
entered into this Agreement in connection with the conduct of Company’s
business or to manage the risk associated with an asset or liability owned or

of Company’s business.

 

8

 

	 	(g)	 	Company and each of its affiliates is not, on the date hereof, in possession of
any material non-public information with respect to Company.

	 
	 	(h)	 	Company is entering into the Transaction for bona fide business purposes and
not for speculative purposes.

	9.	 	Other Provisions:

	 	(a)	 	Opinions. Company shall deliver to Dealer an opinion of counsel, dated
as of the Trade Date and reasonably acceptable to Dealer in form and substance, with
respect to (i) due incorporation, existence and good standing of Company in Delaware,
(ii) Company’s qualifications as a foreign corporation and good standing in Texas,
(iii) the due authorization, execution and delivery of the Confirmation, and (iv) the
absence of conflict of the execution and delivery of the Confirmation with any material
agreement required to be filed as any exhibit to Company’s Annual Report on Form 10-K,
Company’s charter documents and any applicable law or regulation. Delivery of such
opinion to Dealer shall be a condition precedent for the purpose of Section 2(a)(iii)
of the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of the
Agreement.

	 
	 	(b)	 	Repurchase Notices. Company shall, on any day on which Company effects
any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a
“Repurchase Notice”) on such day if following such repurchase, the number of
outstanding Shares on such day, subject to any adjustments provided herein, is (i) less
than 56.5 million (in the case of the first such notice) or (ii) thereafter more than
5.4 million less than the number of Shares included in the immediately preceding
Repurchase Notice. Company agrees to indemnify and hold harmless Dealer and its
affiliates and their respective officers, directors, employees, affiliates, advisors,
agents and controlling persons (each, an “Indemnified Person”) from and against any and
all losses (including losses relating to Dealer’s hedging activities as a consequence
of becoming, or of the risk of becoming, a Section 16 “insider”, including without
limitation, any forbearance from hedging activities or cessation of hedging activities
and any losses in connection therewith with respect to this Transaction), claims,
damages, judgments, liabilities and expenses (including reasonable attorney’s fees),
joint or several, which an Indemnified Person actually may become subject to, as a
result of Company’s failure to provide Dealer with a Repurchase Notice on the day and
in the manner specified in this paragraph, and to reimburse, within 30 days, upon
written request, each of such Indemnified Persons for any reasonable legal or other
expenses incurred in connection with investigating, preparing for, providing testimony
or other evidence in connection with or defending any of the foregoing. If any suit,
action, proceeding (including any governmental or regulatory investigation), claim or
demand shall be brought or asserted against the Indemnified Person, such Indemnified
Person shall promptly notify Company in writing, and Company, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified
Person to represent the Indemnified Person and any others Company may designate in such
proceeding and shall pay the fees and expenses of such counsel related to such
proceeding. Company shall not be liable for any settlement of any proceeding effected
without its written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, Company agrees to indemnify any Indemnified Person from and
against any loss or liability by reason of such settlement or judgment. Company shall
not, without the prior written consent of the Indemnified Person, effect any settlement
of any pending or threatened proceeding in respect
of which any Indemnified Person is or could have been a party and indemnity could
have been sought hereunder by such Indemnified Person, unless such settlement
includes an unconditional release of such Indemnified Person from all liability on
claims that are the subject matter of such proceeding on terms reasonably
satisfactory to such Indemnified Person. If the indemnification provided for in
this paragraph is unavailable to an Indemnified Person or insufficient in respect of
any losses, claims, damages or liabilities referred to therein, then Company under
such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall
contribute to the amount paid or payable by such Indemnified Person as a result of
such losses, claims, damages or liabilities. The remedies provided for in this
paragraph are not exclusive and shall not limit any rights or remedies which may
otherwise be available to any Indemnified Person at law or in equity. The indemnity
and contribution agreements contained in this paragraph shall remain operative and
in full force and effect regardless of the termination of this Transaction.

	 	(c)	 	Regulation M. Company is not on the date hereof engaged in a
distribution, as such term is used in Regulation M under the Securities Exchange Act of
1934, as amended (the “Exchange Act”), of any securities of Company, other than the
distribution of USD 325,000,000 principal amount of 4.25% convertible senior notes due
2014 being made on the date hereof. Company shall not, until the second Scheduled
Trading Day immediately following the Effective Date, engage in any such distribution.

	 
	 	(d)	 	No Manipulation. Company is not entering into this Transaction to
create actual or apparent trading activity in the Shares (or any security convertible
into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the
price of the Shares (or any security convertible into or exchangeable for the Shares)
or otherwise in violation of the Exchange Act.

	 
	 	(e)	 	Transfer or Assignment. Company may not transfer any of its rights or
obligations under this Transaction without the prior written consent of Dealer. Dealer
may, without Company’s consent, transfer or assign all or any part of its rights or
obligations under this Transaction to any third party. If at any time at which (1) the
Section 16 Percentage exceeds 7.5%, (2) the Warrant Equity Percentage exceeds 14.5%, or
(3) the Share Amount exceeds the Post-Effective Limit (if any applies), Dealer is
unable after using its commercially reasonable efforts to effect a transfer or
assignment of Warrants to a third party on pricing terms reasonably acceptable to
Dealer and within a time period reasonably acceptable to Dealer such that (1) the
Section 16 Percentage will be equal to or less than 7.5%, (2) the Warrant Equity
Percentage will be equal to or less than 14.5%, and (3) the Share Amount will be equal
to or less than any such Post-Effective Limit, then Dealer may designate any Exchange
Business Day as an Early Termination Date with respect to a portion of the Transaction
(the “Terminated Portion”), such that following such partial termination (1) the
Section 16 Percentage will be equal to or less than 7.5%, (2) the Warrant Equity
Percentage will be equal to or less than 14.5%, and (3) the Share Amount will be equal
to or less than such Post-Effective Limit. In the event that Dealer so designates an
Early Termination Date with respect to a Terminated Portion, a payment shall be made
pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been
designated in respect of a Transaction having terms identical to this Transaction and a
Number of Warrants equal to the number of Warrants underlying the Terminated Portion,
(2) Company shall be the sole Affected Party with respect to such partial termination
and (3) the Terminated Portion shall be the sole Affected Transaction (and, for the
avoidance of doubt, the provisions of Section 9(j) shall apply to any amount that is
payable by Company to Dealer pursuant to this sentence as if Company was not the
Affected Party). The “Section 16 Percentage” as of any day is the fraction, expressed
as a percentage, (A) the numerator of which is the number of Shares that Dealer and
each person subject to aggregation of Shares with Dealer under Section 13 or Section 16
of the Exchange Act and rules promulgated thereunder (the “Dealer Group”) directly or
indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange
Act and rules promulgated thereunder) and (B) the denominator of which is the number of
Shares outstanding. The “Warrant Equity Percentage” as of any day is the fraction,
expressed as a percentage, (A) the numerator of which is the sum of (x) the product of
the Number of Warrants and the Warrant Entitlement and (y) the aggregate number of
Shares underlying any other warrants purchased by Dealer from Company, and (B) the
denominator of which is the number of Shares 

 

10

 

	 	 	 	outstanding. The
“Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership
position would be aggregated with that of Dealer (Dealer or any such person, a
“Dealer Person”) under any law, rule, regulation or regulatory order that for any
reason becomes applicable to ownership of Shares after the Trade Date (“Applicable
Laws”), owns, beneficially owns, constructively owns, controls, holds the power to
vote or otherwise meets a relevant definition of ownership of under the Applicable
Laws, as determined by Dealer in its reasonable discretion. The “Post-Effective
Limit” means (x) the minimum number of Shares that would give rise to reporting or
registration obligations or other requirements (including obtaining prior approval
from any person or entity) of a Dealer Person, or would result in an adverse effect
on a Dealer Person, under the Applicable Laws, as determined by Dealer in its
reasonable discretion, minus (y) 1% of the number of Shares outstanding.
Notwithstanding any other provision in this Confirmation to the contrary requiring
or allowing Dealer to purchase, sell, receive or deliver any Shares or other
securities to or from Company, Dealer may designate any of its affiliates to
purchase, sell, receive or deliver such Shares or other securities and otherwise to
perform Dealer’s obligations in respect of this Transaction and any such designee
may assume such obligations. Dealer shall be discharged of its obligations to
Company to the extent of any such performance.

	 
	 	(f)	 	Dividends. If at any time during the period from and including the
Effective Date, to and including the final Expiration Date, an ex-dividend date for a
cash dividend occurs with respect to the Shares, then the Calculation Agent will adjust
any of the Strike Price, Number of Warrants and/or Daily Number of Warrants to preserve
the fair value of the Warrants to Dealer after taking into account such dividend.

	 
	 	(g)	 	Role of Agent. Credit Suisse, New York branch, in its capacity as
Agent will be responsible for (A) effecting this Transaction, (B) issuing all required

arising from any failure by Dealer or Company to pay or perform any obligations
hereunder, or to monitor or enforce compliance by Dealer or Company with any

a result of this Transaction. Agent shall otherwise have no liability in respect of
this Transaction, except for its gross negligence or willful misconduct in
performing its duties as Agent.

(ii) Notwithstanding anything to the contrary in this Confirmation, upon the
occurrence of one of the following events, with respect to this Transaction, (1)
Dealer shall have the right to designate such event an Additional Termination Event
and designate an Early Termination Date pursuant to Section 6(b) of the Agreement,
and (2) Company shall be deemed the sole Affected Party and the Transaction shall be
deemed the sole Affected Transaction:

(A) A “person” or “group” within the meaning of Section 13(d) of the Exchange
Act, other than Company, its subsidiaries and its and their employee benefit
plans, has become the direct or indirect “beneficial owner,” as defined in Rule
13d-3 under the Exchange Act, of the common equity of Company representing more
than 50% of the voting power of such common equity.

(B) Consummation of any share exchange, consolidation or merger of Company or
any other transaction or series of transactions pursuant to which the Shares
will be converted into cash, securities or other property or any sale, lease or
other transfer in one transaction or a series of transactions of all or
substantially all of the consolidated assets of Company and its subsidiaries,
taken as a whole, to any person other than one of Company’s subsidiaries;
provided, however, that a transaction where the holders of all classes of
Company’s common equity immediately prior to such transaction that is a share
exchange, consolidation or merger own, directly or indirectly, more than 50% of
all classes of common equity of the continuing or surviving corporation or
transferee or the parent thereof immediately after such event shall not
constitute an Additional Termination Event. Notwithstanding the foregoing, any
event set forth in this clause (B) shall not constitute an Additional
Termination Event if at least 90% of the consideration received or to be
received by holders of the Shares, excluding cash payments for fractional
Shares, in connection with such event consists of shares of common stock traded
on the New York Stock Exchange, the NASDAQ Global Market or the NASDAQ Global
Select Market (or any of their respective successors) or which will be so
traded or quoted when issued or exchanged in connection with such event.

(C) An event of default as defined in any mortgage, indenture or instrument
under which there may be issued, or by which there may be secured or evidenced,
any indebtedness of Company or any principal subsidiary (other than Exterran
Partners, L.P. and its subsidiaries, so long as Exterran Partners, L.P. and its
subsidiaries are not restricted subsidiaries of Company, as such term is
defined in the Senior Secured Credit Agreement dated August 20, 2007 by and
among Company, Exterran Canada, Limited Partnership and the agents and lenders
party thereto) for money borrowed, whether such indebtedness now exists or
shall hereafter be created, shall happen and shall result in such indebtedness
in principal amount in excess of $50 million becoming or being declared due and
payable prior to the date on which it would otherwise become due and payable.

(D) Dealer, despite using commercially reasonable efforts, is unable or
reasonably determines that it is impractical or illegal, to hedge its exposure
with respect to this Transaction in the public market without registration
under the Securities Act or as a result of any legal, regulatory or
self-regulatory requirements or related policies and procedures (whether or not
such requirements, policies or procedures are imposed by law or have been
voluntarily adopted by Dealer).

 

13

 

(E) At any time on any day during the period from and including the Trade Date,
to and including the final Expiration Date, (1) the Share Delivery Quantity of
Shares that would be deliverable (if such time were the Valuation Time and such
date were the Exercise Date and
Valuation Date for a number of Warrants equal to the Number of Warrants as of
such date and Net Share Settlement applied) exceeds a number of Shares equal to
75% of the Maximum Number of Shares, or (2) Company makes a public announcement
of any transaction or event that, in the reasonable opinion of Dealer would,
upon consummation of such transaction or upon the occurrence of such event, as
applicable, and after giving effect to any applicable adjustments hereunder,
cause the Share Delivery Quantity of Shares immediately following the
consummation of such transaction or the occurrence of such event (determined as
if the time immediately following the consummation of such transaction or the
occurrence of such event were the Valuation Time and the date upon which such
transaction is consummated or such event occurs were the Exercise Date and
Valuation Date for a number of Warrants equal to the Number of Warrants as of
such Date and Net Share Settlement applied) to exceed a number of Shares equal
to 75% of the Maximum Number of Shares.

	 	(i)	 	No Collateral or Setoff. Notwithstanding any provision of the
Agreement or any other agreement between the parties to the contrary, the obligations
of Company hereunder are not secured by any collateral. Obligations under this
Transaction shall not be set off by Company against any other obligations of the
parties, whether arising under the Agreement, this Confirmation, under any other
agreement between the parties hereto, by operation of law or otherwise. Any provision
in the Agreement with respect to the satisfaction of Company’s payment obligations to
the extent of Dealer ‘s payment obligations to Company in the same currency and in the
same Transaction (including, without limitation Section 2(c) thereof) shall not apply
to Company and, for the avoidance of doubt, Company shall fully satisfy such payment
obligations notwithstanding any payment obligation to Company by Dealer in the same
currency and in the same Transaction. In calculating any amounts under Section 6(e) of
the Agreement, notwithstanding anything to the contrary in the Agreement, (1) separate
amounts shall be calculated as set forth in such Section 6(e) with respect to (a) this
Transaction and (b) all other Transactions, and (2) such separate amounts shall be
payable pursuant to Section 6(d)(ii) of the Agreement. For the avoidance of doubt and
notwithstanding anything to the contrary provided in this Section 9(i), in the event of
bankruptcy or liquidation of either Company or Dealer neither party shall have the
right to set off any obligation that it may have to the other party under this
Transaction against any obligation such other party may have to it, whether arising
under the Agreement, this Confirmation or any other agreement between the parties
hereto, by operation of law or otherwise.

	 
	 	(j)	 	Alternative Calculations and Payment on Early Termination and on Certain
Extraordinary Events. If, in respect of this Transaction, an amount is payable by
Company to Dealer, (i) pursuant to Section 12.7 or Section 12.9 of the Equity
Definitions, (ii) pursuant to Section 6(d)(ii) of the Agreement or (iii) pursuant to
Section 9(t) (a “Payment Obligation”), Company shall have the right, in its sole
discretion, to satisfy any such Payment Obligation by the Share Termination Alternative
(as defined below) (except that Company shall not make such an election in the event of
a Nationalization, Insolvency, Merger Event or Tender Offer in which the consideration
to be paid to holders of shares consists solely of cash or an Event of Default in which
Company is the Defaulting Party or a Termination Event in which Company is the Affected
Party, other than an Event of Default of the type described in Section 5(a)(iii), (v),
(vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in
Section 5(b) of the Agreement, in each case that resulted from an event or events
outside Company’s control) and shall give irrevocable telephonic notice to Dealer,
confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New
York City time) on the Merger Date, Tender Offer Date, Announcement Date (in the case
of a Nationalization, Insolvency or Delisting), Early Termination Date or date of
cancellation, or no later than 6:00 p.m. (New York City time) on the Early Unwind Date,
as applicable; provided that if Company does not validly elect to satisfy its Payment
Obligation by the Share Termination Alternative, Dealer shall have the right, in its
reasonable discretion, to require Company to satisfy its Payment Obligation by the
Share Termination Alternative. Notwithstanding the foregoing, Company’s or Dealer’s
right to elect satisfaction of a Payment Obligation in the Share Termination
Alternative as set forth in this clause shall only apply to Transactions under this
Confirmation and, notwithstanding anything to the contrary in the Agreement, (1)
separate amounts shall be calculated with respect to (a) Transactions hereunder and (b)
all other
Transactions under the Agreement, and (2) such separate amounts shall be payable
pursuant to Section 6(d)(ii) of the Agreement, subject to, in the case of clause
(a), Company’s Share Termination Alternative right hereunder.

 

14

 

	 	 	 
	Share Termination Alternative:

	 	If applicable, Company shall deliver
to Dealer the Share Termination Delivery Property on the date (the “Share
Termination Payment Date”) on which the Payment Obligation would otherwise be
due pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or
Section 6(d)(ii) of the Agreement, or on the Exchange Business Day immediately
following the date on which the Payment Obligation would otherwise be due
pursuant to Section 9(t), as applicable, subject to paragraph (k)(i) below, in
satisfaction, subject to paragraph (k)(ii) below, of the Payment Obligation in
the manner reasonably requested by Dealer free of payment.
	 
	 	 
	Share Termination Delivery Property:

	 	A number of Share Termination
Delivery Units, as calculated by the Calculation Agent, equal to the Payment
Obligation divided by the Share Termination Unit Price. The Calculation Agent
shall adjust the amount of Share Termination Delivery Property by replacing any
fractional portion of a security therein with an amount of cash equal to the
value of such fractional security based on the values used to calculate the
Share Termination Unit Price.
	 
	 	 
	Share Termination Unit Price:

	 	The value to Dealer of property
contained in one Share Termination Delivery Unit on the date such Share
Termination Delivery Units are to be delivered as Share Termination Delivery
Property, as determined by the Calculation Agent in its discretion by
commercially reasonable means. The Calculation Agent shall notify Company of
such Share Termination Unit Price at the time of notification of the Payment
Obligation. In the case of a Private Placement of Share Termination Delivery
Units that are Restricted Shares (as defined below), as set forth in paragraph
(k)(i) below, the Share Termination Unit Price shall be determined by the
discounted price applicable to such Share Termination Delivery Units. In the
case of a Registration Settlement of Share Termination Delivery Units that are
Restricted Shares (as defined below) as set forth in paragraph (k)(ii) below,
the Share Termination Unit Price shall be the Settlement Price on the Merger
Date, the Tender Offer Date, the Announcement Date (in the case of a
Nationalization, Insolvency or Delisting), the date of cancellation, the Early
Termination Date or the Early Unwind Date, as applicable.

 

15

 

	 	 	 
	 
	 	 
	Share Termination Delivery Unit:

	 	In the case of a Termination Event,
Event of Default Additional Disruption Event, Delisting or Early Unwind, one
Share or, in the case of Nationalization, Insolvency, Tender Offer or Merger
Event, a unit
consisting of the number or amount of each
type of property received by a holder of one
Share (without consideration of any
requirement to pay cash or other consideration
in lieu of fractional amounts of any
securities) in such Nationalization,
Insolvency, Tender Offer or Merger Event. If
such Nationalization, Insolvency, Tender Offer
or Merger Event involves a choice of
consideration to be received by holders, such
holder shall be deemed to have elected to
receive the maximum possible amount of cash.
	 
	 	 
	Failure to Deliver:

	 	Inapplicable
	 
	 	 
	Other applicable provisions:

	 	If Share Termination Alternative is
applicable, the provisions of Sections 9.8, 9.9, 9.11, 9.12 and 10.5 (as
modified above) of the Equity Definitions will be applicable, except that all
references in such provisions to “Physically-settled” shall be read as
references to “Share Termination Settled” and all references to “Shares” shall
be read as references to “Share Termination Delivery Units”. “Share
Termination Settled” in relation to this Transaction means that Share
Termination Alternative is applicable to this Transaction.

	 	(k)	 	Registration/Private Placement Procedures. If, in the reasonable
opinion of Dealer, following any delivery of Shares or Share Termination Delivery
Property to Dealer hereunder, such Shares or Share Termination Delivery Property would
be in the hands of Dealer subject to any applicable restrictions with respect to any
registration or qualification requirement or prospectus delivery requirement for such
Shares or Share Termination Delivery Property pursuant to any applicable federal or
state securities law (including, without limitation, any such requirement arising under
Section 5 of the Securities Act as a result of such Shares or Share Termination
Delivery Property being “restricted securities”, as such term is defined in Rule 144
under the Securities Act, or as a result of the sale of such Shares or Share
Termination Delivery Property being subject to paragraph (c) of Rule 145 under the
Securities Act) (such Shares or Share Termination Delivery Property, “Restricted
Shares”), then delivery of such Restricted Shares shall be effected pursuant to either
clause (i) or (ii) below at the election of Company, unless Dealer waives the need for
registration/private placement procedures set forth in (i) and (ii) below.
Notwithstanding the foregoing, solely in respect of any Daily Number of Warrants
exercised or deemed exercised on any Expiration Date, Company shall elect, prior to the
first Settlement Date for the first Expiration Date, a Private Placement Settlement or
Registration Settlement for all deliveries of Restricted Shares for all such Expiration
Dates which election shall be applicable to all Settlement Dates for such Warrants and
the procedures in clause (i) or clause (ii) below shall apply for all such delivered
Restricted Shares on an aggregate basis commencing after the final Settlement Date for
such Warrants. The Calculation Agent shall make reasonable adjustments to settlement
terms and provisions under this Confirmation to reflect a single Private Placement or
Registration Settlement for such aggregate Restricted Shares delivered hereunder.

 

16

 

	 	(i)	 	If Company elects to settle the Transaction pursuant to this
clause (i) (a “Private Placement Settlement”), then delivery of Restricted
Shares by Company shall be effected in customary private placement procedures
with respect to such Restricted Shares reasonably acceptable to Dealer;
provided that Company may not elect a Private Placement Settlement if, on the
date of its election, it has taken, or caused to be taken, any action that
would make unavailable either the exemption pursuant to Section 4(2) of the
Securities Act for the sale by Company to Dealer (or any affiliate designated
by Dealer) of the Restricted
Shares or the exemption pursuant to Section 4(1) or Section 4(3) of the
Securities Act for resales of the Restricted Shares by Dealer (or any such
affiliate of Dealer). The Private Placement Settlement of such Restricted
Shares shall include customary representations, covenants, blue sky and
other governmental filings and/or registrations, indemnities to Dealer, due
diligence rights (for Dealer or any designated buyer of the Restricted
Shares by Dealer), opinions and certificates, and such other documentation
as is customary for private placement agreements, all reasonably acceptable
to Dealer. In the case of a Private Placement Settlement, Dealer shall
determine the appropriate discount to the Share Termination Unit Price (in
the case of settlement of Share Termination Delivery Units pursuant to
paragraph (j) above) or any Settlement Price (in the case of settlement of
Shares pursuant to Section 2 above) applicable to such Restricted Shares in
a commercially reasonable manner and appropriately adjust the number of such
Restricted Shares to be delivered to Dealer hereunder; provided that in no
event shall such number be greater than the Maximum Number of Shares.
Notwithstanding the Agreement or this Confirmation, the date of delivery of
such Restricted Shares shall be the Exchange Business Day following notice
by Dealer to Company, of such applicable discount and the number of
Restricted Shares to be delivered pursuant to this clause (i). For the
avoidance of doubt, delivery of Restricted Shares shall be due as set forth
in the previous sentence and not be due on the Share Termination Payment
Date (in the case of settlement of Share Termination Delivery Units pursuant
to paragraph (j) above) or on the Settlement Date for such Restricted Shares
(in the case of settlement in Shares pursuant to Section 2 above).

	 
	 	 	 	In the event Company shall not have delivered the full number of Restricted
Shares otherwise applicable as a result of the proviso above relating to the
Maximum Number of Shares (such deficit, the “Deficit Restricted Shares”),
Company shall be continually obligated to deliver, from time to time until
the full number of Deficit Restricted Shares have been delivered pursuant to
this paragraph, Restricted Shares when, and to the extent, that (i) Shares
are repurchased, acquired or otherwise received by Company or any of its
subsidiaries after the Trade Date (whether or not in exchange for cash, fair
value or any other consideration), (ii) authorized and unissued Shares
reserved for issuance in respect of other transactions prior to such date
which prior to the relevant date become no longer so reserved and (iii)
Company additionally authorizes any unissued Shares that are not reserved
for other transactions. Company shall immediately notify Dealer of the
occurrence of any of the foregoing events (including the number of Shares
subject to clause (i), (ii) or (iii) and the corresponding number of
Restricted Shares to be delivered) and promptly deliver such Restricted
Shares thereafter.

	 
	 	(ii)	 	If Company elects to settle the Transaction pursuant to this
clause (ii) (a “Registration Settlement”), then Company shall promptly (but in
any event no later than the beginning of the Resale Period) file and use its
reasonable best efforts to make effective under the Securities Act a
registration statement or supplement or amend an outstanding registration
statement in form and substance reasonably satisfactory to Dealer, to cover the
resale of such Restricted Shares in accordance with customary resale
registration procedures, including covenants, conditions, representations,
underwriting discounts (if applicable), commissions (if applicable),
indemnities due diligence rights, opinions and certificates, and such other
documentation as is customary for equity resale underwriting agreements, all
reasonably acceptable to Dealer. If Dealer, in its sole reasonable discretion,
is not satisfied with such procedures and documentation Private Placement
Settlement shall apply. If Dealer is satisfied with such procedures and
documentation, it shall sell the Restricted Shares pursuant to such
registration statement during a period (the “Resale Period”) commencing on the
Exchange Business Day following delivery of such Restricted Shares (which, for
the avoidance of doubt, shall be (x) the Share Termination Payment Date in case
of settlement in Share Termination Delivery Units pursuant to paragraph (j)
above or (y) the Settlement Date in respect of the final Expiration Date for
all Daily Number of Warrants) and ending on the earliest of (i) the

 

17

 

	 	 	 	Exchange
Business Day on which Dealer completes the sale of all Restricted
Shares or, in the case of settlement of Share Termination Delivery Units, a sufficient
number of Restricted Shares so that the realized net proceeds of such sales
equals or exceeds the Payment Obligation (as defined above), (ii) the date
upon which all Restricted Shares have been sold or transferred pursuant to
Rule 144 (or similar provisions then in force) or Rule 145(d)(2) (or any
similar provision then in force) under the Securities Act and (iii) the date
upon which all Restricted Shares may be sold or transferred by a
non-affiliate pursuant to Rule 144 (or any similar provision then in force)
or Rule 145(d)(2) (or any similar provision then in force) under the
Securities Act. If the Payment Obligation exceeds the realized net proceeds
from such resale, Company shall transfer to Dealer by the open of the
regular trading session on the Exchange on the Exchange Trading Day
immediately following the last day of the Resale Period the amount of such
excess (the “Additional Amount”) in cash or in a number of Shares
(“Make-whole Shares”) in an amount that, based on the Settlement Price on
the last day of the Resale Period (as if such day was the “Valuation Date”
for purposes of computing such Settlement Price), has a dollar value equal
to the Additional Amount; provided that in no event shall the number of
Make-Whole Shares exceed the Maximum Number of Shares. The Resale Period
shall continue to enable the sale of the Make-whole Shares. If Company
elects to pay the Additional Amount in Shares, the requirements and
provisions for Registration Settlement shall apply. This provision shall be
applied successively until the Additional Amount is equal to zero. In no
event shall Company deliver a number of Restricted Shares greater than the
Maximum Number of Shares.

	 
	 	(iii)	 	Without limiting the generality of the foregoing, Company
agrees that any Restricted Shares delivered to Dealer, as purchaser of such
Restricted Shares, (i) may be transferred by and among Dealer and its
affiliates and Company shall effect such transfer without any further action by
Dealer and (ii) after the period of 6 months from the Trade Date (or 1 year
from the Trade Date if, at such time, informational requirements of Rule 144(c)
are not satisfied with respect to Company) has elapsed after any Settlement
Date for such Restricted Shares, Company shall promptly remove, or cause the
transfer agent for such Restricted Shares to remove, any legends referring to
any such restrictions or requirements from such Restricted Shares upon request
by Dealer (or such affiliate of Dealer) to Company or such transfer agent,
without any requirement for the delivery of any certificate, consent,
agreement, opinion of counsel, notice or any other document, any transfer tax
stamps or payment of any other amount or any other action by Dealer (or such
affiliate of Dealer).

If the Private Placement Settlement or the Registration Settlement shall not be
effected as set forth in clauses (i) or (ii), as applicable, then failure to effect
such Private Placement Settlement or such Registration Settlement shall constitute
an Event of Default with respect to which Company shall be the Defaulting Party.

	 	(l)	 	Limit on Beneficial Ownership. Notwithstanding any other provisions
hereof, Dealer may not exercise any Warrant hereunder, have the “right to acquire”
(within the meaning of NYSE Rule 312.04(g)) Shares upon exercise of any Warrant
hereunder or be entitled to take delivery of any Shares deliverable hereunder, and
Automatic Exercise shall not apply with respect to any Warrant hereunder, to the extent
(but only to the extent) that, after such receipt of any Shares upon the exercise of
such Warrant or otherwise hereunder, (i) the Share Amount would exceed the
Post-Effective Limit, or (ii) Dealer Group would directly or indirectly beneficially
own (as such term is defined for purposes of Section 13 or Section 16 of the Exchange
Act and rules promulgated thereunder) in excess of 7.5% of the then outstanding Shares
(the “Threshold Number of Shares”). Any purported delivery hereunder shall be void and
have no effect to the extent (but only to the extent) that, after such delivery, (i)
the Share Amount would exceed the Post-Effective Limit, or (ii) Dealer Group would
directly or indirectly so beneficially own in excess of the Threshold Number of Shares.
If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result

	 	(i)	 	Company that, after such
delivery, the Share Amount would not exceed the Post-Effective Limit, and (ii) Dealer
Group would not directly or indirectly so beneficially own in excess of the
Threshold Number of Shares. Company agrees to use its reasonable best efforts to
seek approval from its shareholders in accordance with the requirements of NYSE Rule
312.03(c) for the issuance pursuant to the Transaction of a number of Shares equal
to 1.5 times the original Number of Shares. If Company succeeds in obtaining such
approval for such an increase, then (A) the Maximum Number of Shares shall be
automatically increased to 1.5 times the original Number of Shares and (B) the
Additional Termination Event in Section 9(h)(ii)(E) shall no longer be applicable.

	 
	 	(m)	 	Share Deliveries. Company acknowledges and agrees that, to the extent
the holder of this Warrant is not then an affiliate and has not been an affiliate for
90 days (it being understood that Dealer will not be considered an affiliate under this
paragraph solely by reason of its receipt of Shares pursuant to this Transaction), and
otherwise satisfies all holding period and other requirements of Rule 144 of the
Securities Act applicable to it, any delivery of Shares or Share Termination Delivery
Property hereunder at any time after 6 months from the Trade Date (or 1 year from the
Trade Date if, at such time, informational requirements of Rule 144(c) are not
satisfied with respect to Company) shall be eligible for resale under Rule 144 of the
Securities Act and Company agrees to promptly remove, or cause the transfer agent for
such Shares or Share Termination Delivery Property, to remove, any legends referring to
any restrictions on resale under the Securities Act from the Shares or Share
Termination Delivery Property. Company further agrees that any delivery of Shares or
Share Termination Delivery Property prior to the date that is 6 months from the Trade
Date (or 1 year from the Trade Date if, at such time, informational requirements of
Rule 144(c) are not satisfied with respect to Company), may be transferred by and among
Dealer and its affiliates and Company shall effect such transfer without any further
action by Dealer. Notwithstanding anything to the contrary herein, Company agrees that
any delivery of Shares or Share Termination Delivery Property shall be effected by
book-entry transfer through the facilities of DTC, or any successor depositary, if at
the time of delivery, such class of Shares or class of Share Termination Delivery
Property is in book-entry form at DTC or such successor depositary. Notwithstanding
anything to the contrary herein, to the extent the provisions of Rule 144 of the
Securities Act or any successor rule are amended, or the applicable interpretation
thereof by the Securities and Exchange Commission or any court change after the Trade
Date, the agreements of Company herein shall be deemed modified to the extent
necessary, in the opinion of outside counsel of Company, to comply with Rule 144 of the
Securities Act, as in effect at the time of delivery of the relevant Shares or Share
Termination Delivery Property.

	 
	 	(n)	 	Waiver of Jury Trial. Each party waives, to the fullest extent
permitted by applicable law, any right it may have to a trial by jury in respect of any
suit, action or proceeding relating to this Transaction. Each party (i) certifies that
no representative, agent or attorney of the other party has represented, expressly or
otherwise, that such other party would not, in the event of such a suit, action or
proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the
other party have been induced to enter into this Transaction, as applicable, by, among
other things, the mutual waivers and certifications provided herein.

	 
	 	(o)	 	Tax Disclosure. Effective from the date of commencement of discussions
concerning the Transaction, Company and each of its employees, representatives, or
other agents may disclose to any and all persons, without limitation of any kind, the
tax treatment and tax structure of the Transaction and all materials of any kind
(including opinions or other tax analyses) that are provided to Company relating to
such tax treatment and tax structure.

	 
	 	(p)	 	Maximum Share Delivery. Notwithstanding any other provision of this
Confirmation or the Agreement, in no event will Company be required to deliver more
than the Maximum Number of Shares in the aggregate to Dealer in connection with this
Transaction, subject to the provisions regarding Deficit Restricted Shares

 

19

 

	 	(q)	 	Right to Extend. Dealer may postpone, in whole or in part, any
Expiration Date or any other date of valuation or delivery with respect to some or all
of the relevant Warrants (in which event the Calculation Agent shall make appropriate
adjustments to the Daily Number of Warrants with
respect to one or more Expiration Dates) if Dealer determines, in its commercially
reasonable judgment, that such extension is reasonably necessary or appropriate to
preserve Dealer’s hedging or hedge unwind activity hereunder in light of existing
liquidity conditions or to enable Dealer to effect purchases of Shares in connection
with its hedging, hedge unwind or settlement activity hereunder in a manner that
would, if Dealer were Issuer or an affiliated purchaser of Issuer, be in compliance
with applicable legal, regulatory or self-regulatory requirements, or with related
policies and procedures applicable to Dealer.

	 
	 	(r)	 	Status of Claims in Bankruptcy. Dealer acknowledges and agrees that
this Confirmation is not intended to convey to Dealer rights against Company with
respect to the Transaction that are senior to the claims of common stockholders of
Company in any United States bankruptcy proceedings of Company; provided that nothing
herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the
event of a breach by Company of its obligations and agreements with respect to the
Transaction; provided, further, that nothing herein shall limit or shall be deemed to
limit Dealer’s rights in respect of any transactions other than the Transaction.

	 
	 	(s)	 	Securities Contract; Swap Agreement. The parties hereto intend for:
(a) the Transaction to be a “securities contract” and a “swap agreement” as defined in
the Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”), and
the parties hereto to be entitled to the protections afforded by, among other Sections,
Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code; (b)
a party’s right to liquidate the Transaction and to exercise any other remedies upon
the occurrence of any Event of Default under the Agreement with respect to the other
party to constitute a “contractual right” as described in the Bankruptcy Code; and (c)
each payment and delivery of cash, securities or other property hereunder to constitute
a “margin payment” or “settlement payment” and a “transfer” as defined in the
Bankruptcy Code.

	 
	 	(t)	 	Early Unwind. In the event the sale of the “Underwritten Securities”
(as defined in the Underwriting Agreement) is not consummated with the Underwriters for
any reason, or if Company fails to deliver to Dealer opinions of counsel as required
pursuant to Section 9(a), in each case by 5:00 p.m. (New York City time) on the Premium
Payment Date, or such later date as agreed upon by the parties (the Premium Payment
Date or such later date, the “Early Unwind Date”), the Transaction shall automatically
terminate (the “Early Unwind”), on the Early Unwind Date and (i) the Transaction and
all of the respective rights and obligations of Dealer and Company under the
Transaction shall be cancelled and terminated and (ii) each party shall be released and
discharged by the other party from and agrees not to make any claim against the other
party with respect to any obligations or liabilities of the other party arising out of
and to be performed in connection with the Transaction either prior to or after the
Early Unwind Date; provided that Company shall reimburse Dealer for any costs or
expenses (including market losses) relating to the unwinding of its hedging activities
in connection with the Transaction (including any loss or cost incurred as a result of
terminating, liquidating, obtaining or reestablishing any hedge or related trading
position of Dealer or one or more of its affiliates in connection with the
Transaction). The amount of any such reimbursement shall be determined by Dealer in its
sole good faith discretion. Dealer shall notify Company of such amount and Company
shall pay such amount in immediately available funds on the Early Unwind Date. Each of
Dealer and Company represent and acknowledge to the other that, subject to the proviso
included in this Section, upon an Early Unwind, all obligations with respect to the
Transaction shall be deemed fully and finally discharged.

	 
	 	(u)	 	Payment by Dealer. In the event that (i) an Early Termination Date
occurs or is designated with respect to the Transaction as a result of a Termination
Event or an Event of Default (other than an Event of Default arising under Section
5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Dealer owes to Company an
amount calculated under Section 6(e) of the Agreement, or (ii) Dealer owes to Company,
pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, an amount
calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to
be zero.

Company hereby agrees (a) to check this Confirmation carefully and immediately upon receipt so
that errors or discrepancies can be promptly identified and rectified and (b) to confirm that the
foregoing (in the exact form provided by Dealer) correctly sets forth the terms of the agreement
between Dealer and Company with respect to the Transaction, by manually signing this Confirmation
or this page hereof as evidence of agreement to such terms and providing the other information
requested herein and immediately returning an executed copy to Credit Suisse, New York branch,

PREMISES, BUILDING, PROJECT, AND COMMON AREAS

     1.1 The Premises. Landlord hereby leases to Tenant and Tenant hereby leases from
Landlord the premises set forth in Section 2.2 of the Summary (the “Premises”) and shown on
Exhibit A, attached hereto. The Premises consist of space on the second, third, fourth and
fifth floors within Building 2 (the “Building”) and shall be deemed to be the number of rentable
square feet set forth in Section 2.2 of the Summary, subject to adjustment in accordance
with Section 4.3, below. Tenant shall not have the right to remeasure the Premises. The
parties hereto agree that the lease of the Premises is upon and subject to the terms, covenants and
conditions (the “TCCs”) herein set forth, and Landlord and Tenant covenant as a material part of
the consideration for this Lease to keep and perform each and all of such terms, covenants and
conditions by it to be kept and performed and that this Lease is made upon the condition of such
performance. During the term of the Lease, Tenant shall have access to Building 4 via the existing
hallway on the second floors of Buildings 1 and 2, and the current enclosed connector between
Buildings 1 and 4 and the telephone-data-riser closet located in Building 2, level 2, which use may
be in common with the other tenants and occupants of the Project. Tenant also acknowledges that
neither Landlord nor any agent of Landlord has made any representation or warranty regarding the
condition of the Premises, the Building or the Project or with respect to the suitability of any of
the foregoing for the conduct of Tenant’s business, except as specifically set forth in this Lease.
Landlord shall not be obligated to provide or pay for any improvement work related to the
improvement of the Premises except as expressly set forth in Section 5.5 and Section
5.7, below. Attached hereto as Exhibit A-1 is a plan for the Building 2 loading dock
area (the “Loading Dock”), which indicates an existing caged holding area which shall be deemed to
be part of the Premises (but shall not be counted as useable square footage for the purposes of
calculating the number of rentable square feet in the Premises) and available for Tenant’s
exclusive use. The use of the Loading Dock by Tenant and other occupants or tenants of the Project
shall be subject to the Rules and Regulations (as defined in Section 5.6, below) respecting
the use of the Loading Dock.

          1.1.1 Interim Premises. Notwithstanding anything to the contrary contained herein,

broom clean and in as good order and condition as when Tenant took possession and as thereafter
improved by Landlord and/or Tenant, reasonable wear and tear, damage due to casualty or
condemnation, or repairs which are specifically made the responsibility of Landlord hereunder
excepted. On or before the last day of the Transition Period, Tenant shall either: (i) relocate
the Furniture located in the Interim Premises on the Lease Commencement Date to the Premises (to be
surrendered to Landlord at the expiration or earlier termination of the Lease) or (ii) surrender
the Furniture located in the Interim Premises on the Lease Commencement Date to Landlord in the
same condition and repair as on the Lease Commencement Date, reasonable wear and tear and damage by
casualty excepted. The Furniture that Tenant expects to surrender to Landlord within the Interim
Premises is set forth on Exhibit C-1. Tenant shall, without expense to Landlord, remove or
cause to be removed from the Interim Premises all debris and rubbish, and such items of furniture
(excepting the Furniture),

other articles of personal property owned by Tenant or installed or placed by Tenant at its expense
in the Interim Premises (excluding, however, Tenant’s Alterations) and Tenant shall repair at its
own expense all damage to the Interim Premises, the Building and/or Building 1 caused by such
removal, on or before the expiration of the Transition Period.

     1.2 The Building and The Project. The Building is part of a complex of buildings
located on the Property consisting of four (4) buildings and other improvements. The term
“Project,” as used in this Lease, shall mean (i) the Building and the Common Areas (as such term is
defined in Section 1.3 below), (ii) the land (which is improved with landscaping, parking
areas, access roads and other improvements) upon which the Building and the Common Areas are
located as shown on the Project Site Plan, and (iii) the three other office buildings (including
without limitation, “Building 1”, “Building 3” and “Building 4”) located adjacent to the Building
and the land upon which such adjacent office buildings are located, all substantially as shown on
the Project Site Plan attached hereto as Exhibit B.

     1.3 Common Areas. Tenant shall have the non-exclusive right to use in common with
Landlord and other tenants in the Project, and subject to the Rules and Regulations (as defined in
Section 5.6, below), those portions of the Building and the Project which are provided,
from time to time, for non-exclusive use in common by Landlord, Tenant and any other tenants of the
Project (such areas, including without limitation parking areas, access roads and sidewalks on the
Project, whether or not shown on the Project Site Plan, and common facilities within the Buildings,
such as lobbies, corridors, stairwells, elevators and restrooms, the Conference Facilities (as
defined in Section 1.3.1, below), Cafeteria (as defined in Section 1.3.2, below)
and Fitness Center (as defined in Section 1.3.2, below), together with such other portions
of the Project designated to Tenant in writing by Landlord to be shared by Landlord and certain
tenants, are collectively referred to herein as the “Common Areas”). Landlord shall maintain and
operate the Common Areas in a manner consistent with Comparable Buildings (as defined in
Section 6.1). Landlord reserves the right to close temporarily or permanently, make
alterations or additions to, or change the location of elements of the Project and the Common
Areas, including, without limitation, the right to (a) make changes in the location, size, shape
and number of driveways, entrances, parking spaces, parking areas, loading and unloading areas,
ingress, egress, direction of traffic, landscaped areas and walkways; (b) to close temporarily any
of the Common Areas for maintenance purposes so long as reasonable access to the Premises remains
available; (c) to add additional improvements to the Common Areas; (d) to use the Common Areas
while engaged in making additional improvements, repairs or alterations to the Project, or any
portion thereof; (e) to do and perform such other acts and make such other changes in, to or with
respect to the Project, Building and Common Areas as Landlord may deem to be appropriate; and (f)
to remove areas from use as Common Areas; provided, however, that Landlord’s exercise of the
foregoing rights shall not materially, adversely interfere with Tenant’s use and occupancy of the
Premises or the Common Areas, other than and excluding the Common Areas of Building 4, any or all
of which may, in Landlord’s sole discretion, be closed temporarily or permanently, or be withdrawn
from Common Areas, subject only to the last two sentences of Section 1.3.2.
Notwithstanding anything to the contrary in this Section 1.3, during the Lease Term no
expansion of the rentable square feet of space included within the Common Areas (whether or not in
connection with future development of the Project) or removal from service of rentable square feet
which was not part of the Common Areas as of the Lease

6

 

Commencement Date shall result in an increase in the load factor included within the
calculation of the size of the Premises for purposes of computing Tenant’s Share.

          1.3.1 Conference and Training Rooms. Subject to availability, and prior reservation
in accordance with any procedures implemented by Landlord and provided in writing to Tenant and
applied uniformly to all tenants, Tenant shall have the right to use the meeting and training
rooms and the auditorium located in Building 4 (collectively, the “Conference Facilities”) in
common with Landlord and other tenants of the Project, to the extent otherwise permitted by
Landlord. The use of the Conference Facilities shall be subject to such rules and requirements
as Landlord may establish and provide in writing to Tenant in accordance with Section 5.6,
below, and to all other provisions of this Section 1.3. Tenant shall have the right to
use the Conference Facilities without any additional charge (beyond Tenant’s Share of Operating
Expenses) so long as its use does not exceed Tenant’s Share of the available days per month, with
Landlord reserving the right to monitor and limit to Tenant’s Share Tenant’s utilization during
normal working hours (versus other hours) or business days (versus holiday and/or weekend days),
in its reasonable business judgment. In addition, Tenant may use the Conference Facilities for
periods of time that exceed Tenant’s Share on a space available basis, and subject to said rules
and requirements, including, without limitation, payment of a fee (“Excess Usage Fee”) for such
usage based on Landlord’s then current schedule, and the other provisions of this Section
1.3.1. The foregoing shall not limit Landlord’s right to include costs of operating the
Conference Facilities in Operating Expenses, subject to, and in accordance with, Section
4.2 below, or to charge Tenant for Excess Usage Fees in accordance with the provisions of this
Section 1.3.1. Notwithstanding any other provision herein to the contrary, Landlord
reserves the right, upon written notice to Tenant, (a) to retain a third party operator to operate
the Conference Facilities, or (b) to lease the Conference Facilities to a third party, provided,
however, in either such case, Landlord shall provide for the right of Tenant to rent, or otherwise
use, the Conference Facilities on the same basis as set forth in this Lease.

          1.3.2 Cafeteria and Fitness Center. Tenant and its employees, contractors, visitors
and consultants shall have the right to use the cafeteria (the “Cafeteria”) located in the Project
so long as it is operational provided such parties shall be responsible for payment of all charges
for meals and other items purchased at the cafeteria. Tenant and its employees, contractors and
consultants shall have access to and the right to use the fitness center (the “Fitness Center”)
located in the Project so long as it is operational provided such parties shall be responsible for
payment of all charges customarily charged by Landlord (or the operator of the Fitness Center) for
the use of the Fitness Center (currently Thirty Dollars ($30)) per month, not to be increased for
Tenant’s employees and contractors by more than five percent (5%) per year). The use of such
facilities by Tenant and/or its employees, contractors, visitors and consultants shall be subject
to compliance with the other provisions of this Section 1.3. Landlord shall have the
right to require that Tenant’s employees sign customary waivers of claims and comply with all
safety and other procedures applicable to use of the Fitness Center. Notwithstanding any other
provision herein to the contrary, Landlord reserves the right, upon written notice to Tenant, (a)
to eliminate Tenant’s right to use the Cafeteria and Fitness Center if Landlord transfers or
assigns its rights to use those facilities to another party and (b) to otherwise reduce, modify or
terminate in whole or in part all or any such services or access to the Cafeteria or Fitness
Center. Landlord shall provide not less than ninety (90) days prior

7

 

written notice to Tenant if the fitness facility will be closed or materially reduced in
size. If Landlord discontinues cafeteria service during the Term, Landlord shall provide an
alternative fresh food (including breakfast items, sandwiches, and salads, but not hot food) and
vending service (not necessarily including any seating area) at the Project sufficient to
reasonably accommodate Tenant’s employees, contractors, visitors and consultants located at the
Project.

     1.4 Furniture. For no additional charge, Landlord hereby leases to Tenant and Tenant
hereby leases from Landlord those items of furniture situated in the Premises and the Interim
Premises (the “Furniture”) and described on the inventory list attached hereto as Exhibit C
(the “Inventory List”). Landlord and Tenant acknowledge that Tenant is currently using said
Furniture and Tenants accepts the Furniture in its “as-is” condition, without any representation or
warranty by Landlord. LANDLORD SPECIFICALLY DISCLAIMS ANY REPRESENTATIONS AND/OR WARRANTIES,
INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR A PARTICULAR
PURPOSE WITH RESPECT TO THE FURNITURE. During the Term of this Lease, Tenant shall maintain and
repair the Furniture as reasonably necessary; provided, however, that Tenant shall be entitled to
remove and store and/or reconfigure the Furniture (e.g., cubicle density and design). Upon the
expiration or earlier termination of this Lease (or on or before the last day of the Transition
Period with respect to Furniture in the Interim Premises not being relocated to the Premises),
Tenant shall surrender the Furniture to Landlord in substantially the same condition and repair as
on the Lease Commencement Date, reasonable wear and tear and damage by casualty excepted; provided,
however, that Tenant shall not be required to relocate the Furniture to the same location within
the Premises or Interim Premises (but shall relocate the Furniture to the Premises or Interim
Premises if it has been stored outside the Premises or Interim Premises) nor restore the Furniture
to the configuration and design as existed on the Lease Commencement Date. Any new or replacement
furniture purchased by Tenant and placed into service in the Premises during the Lease Term shall
remain the personal property of Tenant and shall not be surrendered to Landlord on the expiration
or earlier termination of this Lease, provided, however, that any new or replacement furniture for
which Landlord’s Contribution (hereinafter defined) was applied shall constitute Furniture and
shall be surrendered to Landlord on the expiration or earlier termination of this Lease in
accordance with this Section 1.4. Notwithstanding the foregoing to the contrary, in the
event Tenant replaces any Furniture in the Premises in connection with the Initial Installations,
Tenant shall not surrender such replaced Furniture to Landlord and Tenant shall dispose of such
replaced Furniture at Tenant’s sole cost and expense. After the completion of the Initial
Installations Landlord and Tenant shall update the furniture inventory list in Exhibit C.
If, during the Lease Term and any renewals thereof, Tenant determines that Furniture that is at
least five (5) years old is at an end of life stage due to ordinary wear and tear or casualty and
is not economically feasible to repair (“Obsolete Furniture”), Tenant shall so notify Landlord in
writing and give Landlord the opportunity to take possession of such Obsolete Furniture. In the
event that Landlord does not elect to take possession of said Obsolete Furniture, Tenant shall be
allowed to dispose of said Obsolete Furniture at Tenant’s sole cost and expense and Landlord and
Tenant shall update the inventory of Furniture listed on Exhibit C, provided, however, that
if Tenant sells any of such Obsolete Furniture, all sales proceeds net of any usual and customary,
third-party out-of-pocket costs relating to such sale shall be promptly remitted to Landlord.

8

 

     1.5 Card Key Access. As of the Lease Commencement Date, the Building has card key
access separate from the system for the remainder of the Project and the access to the Building is
controlled by Tenant. Landlord shall have the right, at any time after the Transition Date, to
connect the common areas of the Building, including, without limitation, the entrance ways and
lobby areas of the Building, to the Project-wide card key access system, Tenant’s use of which
shall be subject to the Rules and Regulations (as defined in Section 5.6, below). Tenant
shall have the right to maintain a card key access system for the Premises separate from the system
for the remainder of the Project at Tenant’s sole cost. Except as expressly provided herein,
Tenant shall not have access to those portions of the Building not comprising the Common Areas or
the Premises, which shall remain subject to Landlord’s sole and exclusive control. Nothing herein
shall preclude Landlord from accessing the Premises, subject to the requirements of Article
27, for purposes of undertaking maintenance or repairs or as otherwise provided in this Lease.
Landlord makes no representations or warranties (AND HEREBY EXPRESSLY DISCLAIMS ANY REPRESENTATIONS
AND WARRANTIES, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE AND
ANY WARRANTY OF MERCHANTABILITY) regarding the suitability of any key card access system for
Tenant’s particular purposes. In no event shall Landlord be responsible or liable to Tenant or its
employees for any unauthorized entry upon the Premises or for any failure of the access system to
prevent such entry.

ARTICLE 2

LEASE TERM

     2.1 Lease Term. The TCCs of this Lease shall be effective as of the date of this
Lease as set forth in Section 1 of the Summary (the “Effective Date”). The initial term of
this Lease (the “Initial Term”) shall be as set forth in Section 3.1 of the Summary, shall
commence on the date set forth in Section 3.2 of the Summary (the “Lease Commencement
Date”), and shall terminate on the date set forth in Section 3.3 of the Summary (the “Lease
Expiration Date”) unless this Lease is sooner terminated as hereinafter provided. As used herein,
“Lease Term” shall refer to the Initial Term and to any Option Term(s) which have been duly
exercised.

     2.2 Option to Extend. Provided Tenant is not in default under this Lease (beyond
applicable notice and cure periods) and has not been in default in the payment of recurring monthly
payments of Base Rent, Tenant’s Electricity Cost and/or Tenant’s Share of the Estimated Excess
(beyond applicable notice and cure periods, as set forth in Section 19.1.1, below) under
this Lease more than three (3) times in the prior twelve (12) month period, at the time it
exercises the option or at commencement of the applicable Option Term, Tenant shall have the right
and option to extend this lease (“Option to Extend”) for two (2) additional option periods of three
(3) years each (each, an “Option Term”) upon the same terms and conditions herein set forth except
that the Base Rent shall be adjusted in accordance with Section 2.3 of this Lease. To
exercise its Option to Extend, Tenant must give Landlord notice in writing sent so as to be
received at least twelve (12) months but not more than eighteen (18) months prior to the expiration
of the initial Lease Term or the then current Option Term, as applicable. At Landlord’s election,
Tenant’s exercise of its Option(s) shall be void and of no effect if Tenant is in default under
this Lease (beyond applicable notice and cure periods) or has been in default of any monetary
obligation (beyond applicable notice and cure periods) under this Lease more than

9

 

three times in the prior twelve month period on the date it exercises its Option(s) to Extend
or on the expiration of the Lease Term or Option Term immediately preceding such Option Term, as
applicable. Notwithstanding anything to the contrary, in no event shall Tenant be allowed to
exercise an Option to Extend if Tenant has assigned the Lease to a Transferee other than pursuant
to Section 14.7, below, or if the Tenant and/or its Affiliates are not in possession of at
least two full floors of the Premises (free of any subleases, other than subleases pursuant to
Section 14.7, below).

     2.3 Option Term Rent. For each Option Term, the annual Base Rent payable during said
Option Term shall be equal to Ninety Five Percent (95%) of the annual Fair Market Rent (as
hereinafter defined) of the Premises as of commencement of such Option Term (the “Option Term Lease
Commencement Date”). “Fair Market Rent” shall mean the fair market annual rental value of the
Premises as of the Option Term Lease Commencement Date for a term equal to the Option Term, based
on comparable space in the Project, or on comparable space in Comparable Buildings, including all
of Landlord’s services provided for in this Lease. The calculation of Fair Market Rent shall also
be adjusted to take into account inducements (e.g. improvement allowances, rent concessions),
brokerage commissions and all other relevant factors. For each Option Term, Landlord shall advise
Tenant (the “Rent Notice”) of Landlord’s determination of Fair Market Rent prior to the applicable
Option Term Lease Commencement Date. If Tenant disputes Landlord’s determination of Fair Market
Rent, then Tenant shall give notice (a “Dispute Notice”) to Landlord of such dispute within ten
(10) days after delivery of the Rent Notice, and such dispute shall be resolved by arbitration as
provided in Section 2.4 below. Time is of the essence of the giving of said Dispute
Notice. For each Option Term, if the Base Rent payable during such Option Term is not determined
prior to the applicable Option Term Lease Commencement Date, then Tenant shall pay Base Rent in an
amount equal to the Fair Market Rent for the Premises as determined by Landlord (the “Interim
Rent”). Upon final determination of the Base Rent for such Option Term, Tenant shall commence
paying such Base Rent as so determined, and within ten (10) days after such determination Tenant
shall pay any deficiency in prior payments of Base Rent or, if the Base Rent as so determined shall
be less than the Interim Rent for such Option Term, Tenant shall be entitled to a credit against
the next succeeding installments of Base Rent in an amount equal to the difference between each
installment of Interim Rent and the Base Rent as so determined which should have been paid for such
installment until the total amount of the over payment has been recouped.

     2.4 Arbitration. If Tenant disputes Landlord’s determination of Fair Market Rent
pursuant to Section 2.3, such dispute shall be determined by arbitration in accordance with
the then prevailing Expedited Procedures of the American Arbitration Association or its successor
for arbitration of commercial disputes, except that the Expedited Procedures shall be modified as
follows:

     (1) In its Dispute Notice Tenant shall specify the name and address of the person to act as
the arbitrator on Tenant’s behalf. The arbitrator shall be a commercial real estate appraiser with
the M.A.I. designation from the American Institute of Real Estate Advisors, with at least ten (10)
years full-time commercial real estate appraisal experience who is familiar with the Fair Market
Rent of first-class office space in the Marlborough, Massachusetts area. Failure on the part of
Tenant to make the timely and proper demand for such arbitration shall constitute a waiver of the
right thereto and the Base Rent shall be as set forth in the Rent Notice. Within ten

10

 

(10) business days after receipt of the Dispute Notice, Landlord shall give notice to Tenant
specifying the name and address of the person designated by Landlord to act as arbitrator on its
behalf, which arbitrator shall be similarly qualified. If Landlord fails to notify Tenant of the
appointment of its arbitrator within such ten (10) business day period, then the arbitrator
appointed by Tenant shall be the arbitrator to determine the Fair Market Rent for the Premises.

     (2) If two (2) arbitrators are chosen pursuant to Subsection 2.4(1), the arbitrators
so chosen shall meet within ten (10) business days after the second arbitrator is appointed and
shall seek to reach agreement on Fair Market Rent. If within twenty (20) business days after the
second arbitrator is appointed the two arbitrators are unable to reach agreement on Fair Market
Rent then the two (2) arbitrators shall appoint a third arbitrator, who shall be a competent and
impartial person with qualifications similar to those required of the first two (2) arbitrators
pursuant to Subsection 2.4(1). If they are unable to agree upon such appointment within
five (5) business days after expiration of such twenty (20) business day period, the third
arbitrator shall be selected by the parties themselves. If the parties do not agree on the third
arbitrator within five (5) business days after expiration of the foregoing five (5) business day
period, then either party, on behalf of both, may request appointment of such a qualified person by
the Boston Office of the American Arbitration Association. The third arbitrator shall decide the
dispute, if it has not been previously resolved, by following the procedures set forth in
Subsection 2.4(3). Each party shall pay the fees and expenses of its respective arbitrator
and both shall share the fees and expenses of the third arbitrator. Attorneys’ fees and expenses
of counsel and of witnesses for the respective parties shall be paid by the respective party
engaging such counsel or calling such witnesses.

     (3) In the event that Tenant’s and Landlord’s arbitrators cannot reach an agreement on Fair
Market Rent, and therefore must appoint a third arbitrator in accordance with Subsection 2.4
(2), the Fair Market Rent shall be fixed by the third arbitrator in accordance with the
following procedures. Concurrently with the appointment of the third arbitrator, each of the
arbitrators selected by the parties shall state, in writing, his or her determination of the Fair
Market Rent supported by the reasons therefor. The third arbitrator shall have the right to
consult experts and competent authorities for factual information or evidence pertaining to a
determination of Fair Market Rent, but any such determination shall be made in the presence of both
parties with full right on their part to cross-examine. The third arbitrator shall conduct such
hearings and investigations as he or she deem appropriate and shall, within thirty (30) days after
being appointed, select which of the two (2) proposed determinations most closely approximates his
or her determination of Fair Market Rent. The third arbitrator shall have no right to propose a
middle ground or any modification of either of the two proposed determinations. The determination
he or she chooses as that most closely approximating his or her determination of the Fair Market
Rent shall constitute the decision of the third arbitrator and shall be final and binding upon the
parties. The third arbitrator shall render the decision in writing with counterpart copies to each
party. The third arbitrator shall have no power to add to or modify the provisions of this Lease.
With respect to each Option Term, promptly following receipt of the third arbitrator’s decision,
the parties shall enter into an amendment to this Lease evidencing the extension of the Term for
the Option Term and confirming the Base Rent for the Option Term, but the failure of the parties to
do so shall not affect the effectiveness of the third arbitrator’s determination.

11

 

     (4) In the event of a failure, refusal or inability of any arbitrator to act, his or her
successor shall be appointed by him or her, but in the case of the third arbitrator, his or her
successor shall be appointed in the same manner as that set forth herein with respect to the
appointment of the original third arbitrator.

     (5) The decision of the arbitrators, made in accordance with the above procedures, are final
and binidng on the parites

ARTICLE 3

BASE RENT

Base Rent. Commencing on the Rent Commencement Date, Tenant shall pay, without prior
notice or demand, to Landlord or Landlord’s agent at the management office of the Project, or, at
Landlord’s option, at such other place as Landlord may from time to time designate in writing, by a
check for currency which, at the time of payment, is legal tender for private or public debts in
the United States of America, base rent (“Base Rent”) as set forth in Section 4 of the
Summary, payable in equal monthly installments as set forth in Section 4 of the Summary in
advance on or before the first day of each and every calendar month during the Lease Term, without
any setoff or deduction whatsoever, but subject to abatement as expressly provided in Sections
6.3, 11.1 and 13.1, to the extent applicable, and subject to adjustment in accordance with
Section 4.3, to the extent applicable. If any Rent payment date (including the Rent
Commencement Date) falls on a day of the month other than the first day of such month or if any
payment of Rent is for a period which is shorter than one (1) month, the Rent for any fractional
month shall accrue on a daily basis for the period from the date such payment is due to the end of
such calendar month or to the end of the Lease Term at a rate per day which is equal to one three
hundred and sixty fifth (l/365) of the applicable annual Rent. All other payments or adjustments
required to be made under the TCCs of this Lease that require proration on a time basis shall be
prorated on the same basis.

ARTICLE 4

ADDITIONAL RENT

     4.1 General Terms. In addition to paying the Base Rent specified in Article 3
of this Lease, Tenant shall pay “Tenant’s Share” of the annual “Direct Expenses,” as those terms
are defined in Sections 4.2.6 and 4.2.2 of this Lease, respectively, which are in excess of
the amount of Direct Expenses applicable to the “Base Year,” as that term is defined in Section
4.2.1, below; provided, however, that in no event shall any decrease in Direct Expenses for any
Expense Year below Direct Expenses for the Base Year entitle Tenant to any decrease in Base Rent or
any credit against sums due under this Lease. In addition to the foregoing obligations, Tenant
shall also pay “Tenant’s Electricity Cost,” as defined in Section 4.7 of this Lease,
separately from any increases in Direct Expenses. Such payments by Tenant, together with any and
all other amounts payable by Tenant to Landlord pursuant to the TCCs of this Lease, are hereinafter
collectively referred to as the “Additional Rent,” and the Base Rent and the Additional Rent are
herein collectively referred to as “Rent.” All amounts due under this Article 4 as
Additional Rent shall be payable for the same periods and in the same manner as the Base Rent,
provided,

12

 

however, that Tenant’s obligation to pay Additional Rent shall commence upon the Lease
Commencement Date and shall be payable in advance on or before the first day of each and every
calendar month during the Lease Term. The obligations of Tenant to pay the Additional Rent
provided for in this Article 4 shall survive the expiration or earlier termination of the
Lease for such period of time as is required to reconcile the Estimated Excess and Overpayment
Amount of Direct Expenses pursuant to Section 4.4.1 hereof; provided, however, that any
other contingent or unliquidated contractual claims of Landlord or Tenant (e.g., indemnity) shall
survive the expiration or earlier termination of this Lease only for so long as any applicable
statute of limitations would permit such actions under Massachusetts law. For the avoidance of
doubt, Tenant shall not be responsible for any Additional Rent (other than Tenant’s Additional Rent
pursuant to Section 4.8) for the Interim Premises through November 30, 2009.

     4.2 Definitions of Key Terms Relating to Additional Rent. As used in this Article
4, the following terms shall have the meanings hereinafter set forth:

          4.2.1 “Base Year” shall mean the period set forth in Section 5 of the Summary.

          4.2.2 “Direct Expenses” shall mean “Operating Expenses” and “Tax Expenses”.

          4.2.3 “Expense Year” shall apply only to Operating Expenses and shall mean each calendar year
in which any portion of the Lease Term falls, through and including the calendar year in which the
Lease Term expires, provided that Landlord, upon notice to Tenant, may change the Expense Year
from time to time to any other twelve (12) consecutive month period, and, in the event of any such
change, Tenant’s Share of Operating Expenses shall be equitably adjusted for any Expense Year
involved in any such change.

          4.2.4 “Operating Expenses” shall mean, except as otherwise provided in this Section
4.2.4 or otherwise in this Lease, all expenses, costs and amounts of every kind and nature
which Landlord pays or accrues during any Expense Year because of or in connection with the
ownership, management, maintenance, security, repair, replacement, restoration or operation of the
Project, or any portion thereof, subject to the allocation thereof as set forth in Section
4.3, below. Without limiting the generality of the foregoing, Operating Expenses shall
specifically include any and all of the following: (i) the cost of supplying utilities (excepting
Tenant’s Electricity Cost), operating, repairing, maintaining, and renovating the utility,
telephone, and all other systems and equipment and components thereof of the Buildings and the
Project, and the cost of maintenance and service contracts in connection therewith and payments
under any equipment rental agreements; (ii) the cost of all insurance carried by Landlord in
connection with the Project and any deductibles; (iii) the cost of landscaping the Project, or any
portion thereof; (iv) costs incurred in connection with repairs, replacements, resurfacing, and

prevailing management fees charged by third parties for Comparable Buildings), consulting fees,
legal fees and accounting fees in connection with the management, operation, maintenance and
repair of the Project; (vi) wages, salaries and other compensation

13

 

and benefits, including taxes levied thereon, of all persons engaged in the operation, maintenance
and security of the Project; provided, however, that wages and/or benefits attributable to
personnel above the level of Project manager or Project engineer shall not be included in
Operating Expenses; and provided further, if such persons are employees of Landlord or an
affiliate of Landlord and also work at projects other than the Property, such costs shall be
allocated based on the percentage of time spent at each project; (vii) the cost of janitorial,
alarm, security and other services, replacement of wall and floor coverings, ceiling tiles and
fixtures in Common Areas, maintenance and replacement of curbs and walkways, repair to roofs and
re-roofing; (viii) costs, fees, charges or assessments imposed by, or resulting from any mandate
imposed on Landlord by, any federal, commonwealth, state or local government for fire and police
protection, trash removal, community services, or other services which are not duplicative of “Tax
Expenses” as that term is defined in Section 4.2.5, below; (ix) any expenses incurred in
repair, restoration or other work necessitated by fire or other casualty to the extent of the
deductible, and (x) any operating expenses and/or deficits from the operation of the Fitness
Facility and/or Cafeteria. Parking lot expenses for resurfacing and replacement under
Subsection 4.2.4(iv), above, replacement of wall and floor covering and all roof repair
and resurfacing (including membrane) under Subsection 4.2.4(vii), above, and all other
repairs or replacements and other costs incurred in connection with the Project that are capital
in nature under generally accepted accounting principles shall be amortized (with interest at a
commercially reasonable rate) over the useful life of such items (determined in accordance with
Treasury Regulations) and the amortized portion and interest applicable to the respective Expense
Year shall be included in Operating Expenses.

     Notwithstanding anything in this Section 4.2.4 to the contrary, for purposes of this
Lease, Operating Expenses shall not, however, include the following:

     (A) marketing costs, costs of leasing commissions, renovations, attorneys’ fees and
other costs and expenses incurred in connection with negotiations, disputes or litigation
with present or prospective tenants or other occupants of the Project;

     (B) any expense resulting from the gross negligence or willful misconduct of Landlord,
its agents, contractors or employees;

     (C) interest, principal, points and fees on debts or amortization on any mortgage or

     (E) expenses to the extent Landlord will be reimbursed by another source (excluding
Operating Expense reimbursements by tenants), including without limitation replacement of
any items covered by warranties;

     (F) costs incurred to benefit (or resulting from) a specific tenant or items and
services selectively supplied to any tenant other than Tenant (e.g., excess utilities);

     (M) cost of the initial stock of tools and equipment for operation, repair and
maintenance of the Building;

     (N) costs associated with maintaining Landlord’s existence as a corporation or other
legal entity; and

     (O) all electrical charges included in Tenant’s Electricity Cost.

     Notwithstanding anything to the contrary herein contained, for purposes of computing Operating
Expenses, the Controllable Operating Expenses (hereinafter defined) shall not increase by more than
four percent (4%) per Expense Year on a compounding and cumulative basis over the course of the
term of this Lease. In other words, the amount of Controllable Operating Expenses, as hereinafter
defined, for each Expense Year during the term of this Lease which may be included in Operating
Expenses shall not exceed the Controllable Expense Cap, as hereinafter defined, for such Expense
Year. The “Controllable Expense Cap” for 2011 shall be one hundred four percent (104%) of the
amount of Controllable Operating Expenses (as the same may be adjusted pursuant to Section
4.3) included in Operating Expenses for 2010. The “Controllable Expense Cap” for each Expense
Year after 2011 shall be one hundred four (104%) percent of the Controllable Expense Cap for the
immediately preceding Expense Year (as the same may be adjusted pursuant to Section 4.3).
“Controllable Operating Expenses” shall be defined as any Operating Expenses which are within the
reasonable control of Landlord, and shall expressly exclude, without limitation: (i) fuel, (ii)
other utility costs, (iii) insurance, (iv) taxes, (v) fire safety cost increases caused by changes
to fire codes, laws and regulations, (vi) snow removal and (vii) capital improvements.

          4.2.5 Taxes.

               4.2.5.1 “Tax Expenses” shall mean all federal, state, commonwealth, county, or local
governmental or municipal taxes, fees, charges or other impositions of every kind and nature,
whether general, special, ordinary or extraordinary, (including, without
limitation, real estate taxes, general and special assessments, transit taxes, leasehold taxes
or taxes based upon the receipt of rent, measured as if the Project were the only property owned by

15

 

Landlord, including gross receipts, service tax, value added tax or sales taxes applicable to the
receipt of rent or services provided herein, and unless required to be paid by Tenant, personal
property taxes imposed upon the fixtures, machinery, equipment, apparatus, systems and equipment,
appurtenances, furniture and other personal property used in connection with the Project, or any
portion thereof), which shall be paid or accrued during any Tax Year (as defined in Section
4.2.5.4) because of or in connection with the ownership, leasing and operation of the Project,
or any portion thereof.

               4.2.5.2 Tax Expenses shall include, without limitation: (i) any tax on the rent, right to rent
or other income from the Project, or any portion thereof, or as against the business of leasing the
Project, or any portion thereof (measured as if the Project were the only property owned by
Landlord); (ii) any assessment, tax, fee, levy, or charge allocable to or measured by the area of
the Premises or the Rent payable hereunder, including, without limitation, any business or gross
income tax or excise tax with respect to the receipt of such rent, or upon or with respect to the
possession, leasing, operating, management, maintenance, alteration, repair, use or occupancy by
Tenant of the Premises, or any portion thereof (measured as if the Project were the only property
owned by Landlord); (iii) any assessment, tax, fee, levy or charge, upon this transaction; and (iv)
the amount of any payments or other consideration (in cash or otherwise) that Landlord is required
to make to any taxing authority in connection with any tax abatement agreements benefiting the
Project.

               4.2.5.3 Any costs and expenses (including, without limitation, reasonable attorneys’ fees)
incurred in attempting to protest, reduce or minimize Tax Expenses shall be included in Tax
Expenses in the Tax Year such expenses are paid. Tenant’s Share of any refunds of Tax Expenses in
excess of the Base Year Tax Expenses shall be credited against Tenant’s Tax Expenses and any excess
shall be refunded to Tenant regardless of when received, based on the Tax Year to which the refund
is applicable, provided that in no event shall the amount to be refunded to Tenant for any such Tax
Year exceed the total amount paid by Tenant as Additional Rent under this Article 4 for
such Tax Year. If Tax Expenses for any period during the Lease Term are increased after payment
thereof for any reason, including, without limitation, error or reassessment by applicable
governmental or municipal authorities, Tenant shall pay Landlord within fifteen (15) business days
after receipt of Landlord’s written demand Tenant’s Share of any such increased Tax Expenses
included by Landlord as Tax Expenses pursuant to the TCCs of this Lease. Notwithstanding anything
to the contrary contained in this Section 4.2.5 (except as set forth in Section
4.2.5.1, above), there shall be excluded from Tax Expenses (i) all excess profits taxes,
franchise taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes,
federal and commonwealth/state income taxes, and other taxes to the extent applicable to Landlord’s
general or net income (as opposed to rents, receipts or income attributable to operations at the
Project), (ii) any items included as Operating Expenses, (iii) any items paid by Tenant under
Section 4.5 of this Lease.

               4.2.5.4 Landlord and Tenant agree that the Base Year for the purposes of calculating Tenant’s
Additional Rent liability for Tax Expenses shall be the calendar year 2010 (which shall be the sum
of one-half (1/2) of the Tax Expenses for the period from July 1, 2009 through June 30, 2010 and
one-half (1/2) of the Tax Expenses for the period from July 1,
2010 through June 30, 2011). Each subsequent twelve (12) month calendar year period (i.e.,
January 1 — December 31) during the Lease Term shall be referred to as a “Tax Year”, prorated

16

 

for any partial Tax Year at the end of the Lease Term. At Landlord’s election, Tenant shall pay
Tenant’s Share of any Tax Excess (as defined in Section 4.4) pursuant to Sections 4.4.1
and 4.4.2, or within fifteen (15) business days after receipt of Landlord’s written demand
following the expiration or earlier termination of the Lease Term. Landlord shall provide copies
of any invoices or other notices from the taxing authorities evidencing the Tax Expenses to Tenant
with Landlord’s annual Statement (as defined in Section 4.4.1) or after receipt of Tenant’s
written request for such documentation.

          4.2.6 “Tenant’s Share” of Operating Expenses and Tax Expenses shall mean the percentage set
forth in Section 6 of the Summary, subject to adjustment as set forth in Section
4.3.

     4.3 Allocation of Direct Expenses. The parties acknowledge that the Building is a
part of a multi-building project and that the costs and expenses incurred in connection with the
Project (i.e. the Direct Expenses) will be shared between the tenants and occupants of the Building
and the tenants and occupants of the other buildings in the Project. Accordingly, as set forth in
Section 4.2 above, Direct Expenses shall be determined for the Project as a whole, and
Tenant shall be responsible for paying Tenant’s Share of the Direct Expenses, provided, however,
Landlord in its sole discretion, may determine and allocate some or all Direct Expenses for each
Building, in which case Tenant’s Share of such Direct Expenses shall be based on the percentage
equal to its proportionate share of the building in question. To the extent the entire Project is
not fully occupied, Landlord shall adjust the variable components of Operating Expenses for the
Base Year (and at Landlord’s option, Landlord may adjust the variable components of Operating
Expenses for any Expense Year if the Project is not fully occupied in such Expense Year), based on
Landlord’s reasonable, good faith estimate based on historical operating expense information for
the Project or other reasonable data available to Landlord, to determine the amount of Operating
Expenses that would have been incurred in the Project had the Project been one hundred percent
(100%) occupied; and the amount so determined shall be deemed to have been the amount of Operating
Expenses for such year attributable to the Project. If, during the Lease Term: (a) any portion of
rentable square feet of the Common Areas is converted for exclusive use by occupants of the Project
other than Tenant, such that Tenant no longer has use thereof as contemplated by the terms of this
Lease, the rentable square feet of the Premises shall be recalculated according to the BOMA
Standard, and Base Rent for the Premises and Tenant’s Share shall be reduced accordingly as of the
date such areas are no longer available for use by Tenant as contemplated by this Lease, and /or
(b) additional rentable square feet of improvements which are not Common Areas are added to the
Project, Tenant’s Share shall be reduced accordingly as of the date such rentable square feet are
occupied by a tenant or occupant that is entitled to the exclusive use thereof. In no event shall
Tenant’s Share be increased. In no event shall Landlord be entitled to collect from tenants more
than one hundred percent (100%) of Direct Expenses.

     4.4 Calculation and Payment of Additional Rent. With respect to Operating Expenses,
if for any Expense Year ending or commencing within the Lease Term, Tenant’s Share of Operating
Expenses for such Expense Year exceeds the annualized amount of Tenant’s Share of Operating
Expenses applicable to the Base Year, then Tenant shall pay to Landlord, in
the manner set forth in Sections 4.4.1 and 4.4.2, below, and as Additional Rent, an
amount equal to the excess (the “OE Excess”). With respect to Tax Expenses, if for any Tax Year
ending or

17

 

commencing within the Lease Term, Tenant’s Share of Tax Expenses for such Tax Year
exceeds the annualized amount of Tenant’s Share of Tax Expenses applicable to the Base Year, then
Tenant shall pay to Landlord, in the manner set forth in Sections 4.4.1 and 4.4.2, below,
and as Additional Rent, an amount equal to the excess (the “Tax Excess”). The OE Excess plus the
Tax Excess are sometimes referred to herein collectively as the “Excess.”

          4.4.1 Statement of Actual Direct Expenses and Payment by Tenant. Within one hundred
fifty (150) days after the end of each applicable Expense Year, Landlord will deliver to Tenant a
statement (the “Statement”), which shall state the Direct Expenses incurred or accrued for such
preceding Expense Year, and which shall indicate the amount of the Excess, if any. Upon receipt
of the Statement for each applicable Expense Year, if an Excess is present, Tenant shall pay, with
its next installment of Base Rent due, the full amount of the Excess for such Expense Year, less
the amounts, if any, paid during such Expense Year as “Estimated Excess,” as that term is defined
in Section 4.4.2, below. In the event the Statement shows that the amount paid by Tenant
under Section 4.4.2, below, exceeded Tenant’s Share of Direct Expenses for the Expense
Year in question (the “Overpayment Amount”), then Landlord shall credit the Overpayment Amount
against the next due installments of Base Rent and Additional Rent; provided, however, that with
respect to the final Expense Year of the Lease Term, Landlord shall pay to Tenant the Overpayment
Amount, if any, on or before fifteen (15) business days after Tenant’s receipt of such Statement.
The failure of Landlord to timely furnish the Statement for any Expense Year shall not prejudice
Landlord or Tenant from enforcing its rights under this Article 4. Even though the Lease
Term has expired and Tenant has vacated the Premises, when the final determination is made of
Tenant’s Share of Direct Expenses for the Expense Year in which this Lease terminates, if an
Excess is present, Tenant shall pay such amount to Landlord within fifteen (15) business days
after Tenant’s receipt of such final determination. If Tenant provides a written request to
Landlord within one (1) year after receipt of the Statement provided in this Section
4.4.1, Tenant shall be entitled, during reasonable business hours, to review Landlord’s books
and records on which Landlord has calculated all Direct Expenses and shall promptly thereafter
provide its written analysis of Direct Expenses to Landlord. If Tenant’s review discloses any
overpayment by Tenant, Landlord shall refund such amounts within fifteen (15) business days after
receipt of Tenant’s calculations; if Tenant’s review discloses any underpayment by Tenant, Tenant
shall pay such amounts at the time it provides its calculations to Landlord. Tenant’s audit shall
be conducted by either Tenant or a certified public accountant. Tenant’s audit may not be
conducted by an individual or entity that is retained by Tenant primarily on a contingent fee
basis, other than PricewaterhouseCoopers, Deloitte & Touche, Ernst & Young, or KPMG. The results
of the audit shall be kept confidential by Tenant and shall remain a private matter between
Landlord and Tenant. Any dispute between Landlord and Tenant concerning any item of Direct
Expenses shall not relieve Tenant of liability for payment of all other Excess amounts of Direct
Expenses. The provisions of this Section 4.4.1 shall survive the expiration or earlier
termination of the Lease.

          4.4.2 Statement of Estimated Direct Expenses. In addition, Landlord shall cause to
be delivered from time to time, at least annually, an expense estimate statement (the “Estimate
Statement”) which shall set forth Landlord’s reasonable estimate (the “Estimate”)
of what the total amount of Direct Expenses for the then-current Expense Year shall be and
the estimated Excess (the “Estimated Excess”) as calculated by comparing the Direct Expenses

18

 

for such Expense Year, which shall be based upon the Estimate, over the amount of Direct Expenses for
the Base Year. The failure of Landlord to furnish an Estimate Statement for any Expense Year
shall not preclude Landlord from enforcing its rights to collect any Estimated Excess under this
Article 4, nor shall Landlord be prohibited from revising any Estimate Statement or
Estimated Excess theretofore delivered to the extent necessary in Landlord’s reasonable business
judgment. Upon receipt of any Estimate Statement, Tenant shall pay, with its next installment of
Base Rent due, the monthly amount of the Estimated Excess for the then-current Expense Year
indicated on the Estimate Statement. Until a new Estimate Statement is furnished (which Landlord
shall have the right to deliver to Tenant at any time), Tenant shall continue to pay monthly, with
the monthly Base Rent installments, the monthly amount of the Estimated Excess set forth in any
previous Estimate Statement delivered by Landlord to Tenant.

     4.5 Taxes and Other Charges for Which Tenant Is Directly Responsible.

          4.5.1 Tenant shall be liable for and shall pay before delinquency taxes levied against
Tenant’s equipment, furniture, fixtures and any other personal properly located in or about the
Premises (including without limitation taxes levied against the Furniture, if any). If any such
taxes on Tenant’s equipment, furniture, fixtures and any other personal property are levied
against Landlord or Landlord’s property or if the assessed value of Landlord’s property is
increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or
any other personal property and if Landlord pays any properly assessed taxes based upon such
increased assessment, which Landlord shall have the right to do upon fifteen (15) business days
prior written notice to Tenant, including reasonably satisfactory backup documentation evidencing
such expenses, Tenant shall upon fifteen (15) business days notice to Tenant repay to Landlord the
taxes so levied against Landlord or the proportion of such taxes resulting from such increase in
the assessment, as the case may be.

          4.5.2 If the Alterations in the Premises, whether installed and/or paid for by Landlord or
Tenant and whether or not affixed to the real property so as to become a part thereof, are
assessed for real property tax purposes at a valuation higher than the valuation at which tenant
improvements conforming to Landlord’s standard tenant improvements in other space in the Building
leased to or offered to lease to other tenants, which improvements are substantially similar to
those in the Premises as of the Lease Commencement Date (the “Building Standard”), are assessed
(as reasonably determined by Landlord), then the Tax Expenses levied against Landlord or the
property by reason of such excess assessed valuation shall be deemed to be taxes levied against
personal property of Tenant and shall be governed by the provisions of Section 4.5.1,
above. Landlord shall reciprocally enforce this provision against other tenants in the Project.

     4.6 Landlord’s Books and Records. Subject to Tenant’s right to review as provided in
Section 4.4.1, Landlord’s books and records evidencing Operating Expenses will be
conclusive absent manifest error.

     4.7 Tenant’s Electricity Cost. The Landlord has installed a meter or meters to
measure the consumption of electricity by the Tenant on the third, fourth and fifth floors of the
Premises. Tenant shall from and after the Lease Commencement Date pay to Landlord, as

19

 

Additional Rent, on demand from time to time, but not more frequently than monthly, for its consumption of
electricity on the third, fourth and fifth floors of the Premises one hundred percent (100%) of
such electrical costs (“Tenant’s Upper Floor Electricity Costs”). With respect to the portion of
the Premises located on the second floor, Landlord has installed a meter or meters to measure the
consumption of electricity by all of the tenants (including Tenant) on the second floor. Tenant
shall from and after the Lease Commencement Date pay to Landlord, as additional rent, on demand
from time to time, but not more frequently than monthly, for its consumption of electricity
relating to the second floor, a sum equal to its pro rata share of such electrical costs as
reasonably estimated by Landlord, which pro rata share shall be based on a ratio, the numerator of
which is the area of the Premises located on the second floor and the denominator of which is the
aggregate area then occupied by tenants on the second floor or other reasonable estimate by
Landlord such that Tenant is paying its full share of electricity costs for its occupancy of the
second floor (“Tenant’s Second Floor Electricity Costs” and together with Tenant’s Upper Floor
Electricity Costs, “Tenant’s Electricity Costs”). The rate to be paid by Tenant for electricity
shall include the costs incurred by Landlord in maintaining or replacing electrical meters or
submeters, and any taxes or other charges imposed on the Landlord in connection with the sale,
furnishing or redistribution of electricity. Notwithstanding the foregoing, if tenant(s) on the
second floor have elevated electricity needs beyond that commonly associated with “office space,”
Landlord will separately meter Tenant’s second floor electrical usage and thereafter charge Tenant
for its electrical use as measured by such meter(s). Tenant’s Electricity Cost shall only include
all electricity used by Tenant for lights, light fixtures and electrical usage for Tenant’s labs
(other than heating and cooling the Lab Areas which is covered by Section 4.7.2 below),
personal property and equipment in the Premises.

          4.7.1 Notwithstanding anything to the contrary contained in this Lease, Landlord shall have
the right to separately meter (or install a sub-meter or check meter for) any portion of the
Premises and/or for certain systems or equipment in the Building, at Landlord’s sole cost, any
time during the Lease Term and thereafter charge Tenant for its electrical use as measured by such
meter(s).

          4.7.2 Landlord has installed meters (direct, submeters or checkmeters) which enable Landlord
to measure the electricity usage for the air handlers and chillers which service the Lab Areas (as
defined in Section 6.1.1, below) of the Premises. In addition to Tenant’s Electricity
Cost, Tenant shall pay to Landlord, as Additional Rent, seventy percent (70%) of the electrical
expenses attributable to the chillers and air handlers which service the Lab Areas within the
Premises (currently seventy percent (70%) but subject to change in connection with the
contemplated reduction in Lab Areas pursuant to the Initial Installations, in which case it will
be readjusted pursuant to Section 5.7(d)) and such costs shall not be included in the
calculation of Operating Expenses.

     4.8 Additional Rent for Interim Premises. Notwithstanding anything to the contrary
contained herein, in addition to all other sums payable pursuant to this Lease, commencing on the
Lease Commencement Date and continuing until such time as Tenant has vacated the Interim Premises
in accordance with the provisions of Section 1.1.1, above, Tenant
shall pay to Landlord on demand from time to time, but not more frequently than monthly, as
Additional Rent, the sum Landlord reasonably estimates for electricity used by Tenant for lights,
light fixtures, electrical usage for Tenant’s personal property and equipment and Lab Areas.

20

or purpose contrary to the provisions of the Rules and Regulations (as defined in Section
5.6, below), or in violation of the laws of the United States of America, the Commonwealth of
Massachusetts, or the ordinances, regulations or requirements of the local municipal or county
governing body or other lawful authorities having jurisdiction over the Project) including, without
limitation, any such laws, ordinances, regulations or requirements relating to Hazardous Materials
as defined in Section 29.31.1 below. Tenant shall not do or permit anything to be done in
or about the Premises which will in any material way interfere with the rights, safety and quiet
enjoyment of other tenants or occupants of the Building or the Project, or use or allow the
Premises to be used for any unlawful purpose, nor shall Tenant cause, maintain or permit any
nuisance in, on or about the Premises.

     5.3 CC&Rs. Tenant shall comply with all recorded covenants, conditions, and
restrictions currently affecting the Project to the extent they apply to the Premises or the Common
Areas. Additionally, Tenant acknowledges that the Project may be subject to any future covenants,
conditions, and restrictions (the “CC&Rs”), to the extent that Landlord, in its reasonable
discretion, deems reasonably necessary or appropriate, and Tenant agrees that this Lease shall be
subject and subordinate to such CC&Rs to the extent they apply to the Premises or the Common Areas;
provided, however, that this Lease shall only be subordinate to any future
CC&Rs if such CC&Rs do not materially interfere with Tenant’s use and occupancy of the
Premises and Common Areas.

21

 

     5.4 Condition of Premises. Landlord shall deliver the Premises (including, but not
limited to HVAC (as hereinafter defined), electrical, plumbing, sewer and other Building systems,
and the exterior walls, roof, parking area, landscaping and walkways) to Tenant on the Lease
Commencement Date in their “AS IS” condition and Tenant shall accept the Premises in their “AS IS”
condition. Tenant acknowledges that Tenant, not Landlord was responsible for the construction of
the Project and that Tenant has continuously occupied the Premises as a Tenant since November 26,
2002, and Landlord makes no representation or warranty, and specifically disclaims any
representation or warranty concerning the following: (a) whether the Project was constructed in
compliance with all Applicable Laws (as defined in Article 24), and whether any written
notice of noncompliance with Applicable Laws concerning the Project was issued by any governmental
authorities prior to the Lease Commencement Date; (b) whether the Project and the Premises are free
of Hazardous Materials (as defined in Section 29.31) that are required to be reported to
governmental authorities under Applicable Laws, or which would be in violation of any Applicable
Laws; and (c) whether the Building’s electrical, plumbing, heating and ventilation systems are of a
type, design, quality and capacity as commensurate with Comparable Buildings (as defined in
Section 6.1), and whether they are in good working condition and repair as of the Lease
Commencement Date. Other than as expressly set forth in this Lease, Tenant acknowledges that
neither Landlord nor any agent of Landlord has made any representation or warranty with respect to
the Premises or with respect to the present or future suitability of any part of the Premises for
the conduct of Tenant’s business or the uses proposed by Tenant. Tenant hereby accepts the
Premises, the Building, and all improvements thereon, in their existing condition, subject to all
applicable zoning, municipal, county and state (commonwealth) laws, ordinances and regulations
governing and regulating the use of the Premises, and any covenants or restrictions of record, and
accepts this Lease subject to all of the foregoing and to all matters disclosed in this Lease.
Notwithstanding the foregoing, Landlord shall be responsible for repairing or replacing, as
necessary, any latent or other defect or change of condition in the Premises or the Project which
materially and adversely affects Tenant’s use or occupancy of the Premises; provided, however, the
Rent hereunder shall in no case be withheld or diminished because of any such latent or other
defect, any change in the condition thereof or the existence with respect thereto of any violations
of Applicable Laws. Tenant shall have no right to any abatement of Rent except as expressly
provided in Sections 6.3, 11.1 and 13.1.

     5.5 Demising Plan. The Premises are shown on the space plan attached hereto as
Exhibit A and hereby made a part hereof. Within one hundred twenty (120) days after the
Lease Commencement Date, subject to force majeure, Landlord, at its sole cost, shall: (A) replace
the counter tops with new “building standard” laminate quality counter tops in each of the six (6)
bathrooms located on the third, fourth and fifth floors (if Tenant requests a higher quality
counter top than “building standard” laminate quality, Landlord will install such higher quality
counter tops provided that Tenant agrees to pay to Landlord prior to Landlord purchasing and
installing such counter tops the difference in cost between the quality of counter top requested by
Tenant and the “building standard” laminate quality); and (B) construct an exterior walkway and
lighting in accordance with applicable building codes for the fire egress located on the southeast
side of the Building. Subject to Section 5.7, Tenant shall pay its costs associated with
the installation of Tenant’s network and other cabling, telecommunications infrastructure, and all
of its moving costs incurred in connection with Tenant’s occupancy of the Premises. Any work to
be performed by Tenant in connection with Tenant’s initial occupancy (i.e., occupancy beginning on
the Lease Commencement Date) of the Premises or to be performed in connection

22

 

with Tenant’s contemplated initial redesign of the Premises shall be hereinafter referred to as the “Initial
Installations.” All Initial Installations shall be considered to be “Alterations” and shall be
performed in accordance with Article 8.

     5.6 Rules and Regulations. Tenant shall comply with Landlord’s rules and regulations
respecting the management, care, use and safety of the Premises, Building and Project, including
without limitation, parking areas, landscaped areas, walkways, elevators, loading docks, hallways
and other Common Areas and facilities provided for the common use and convenience of tenants. Such
rules and regulations are attached hereto as Exhibit D and may be amended from time to time
at Landlord’s reasonable discretion, upon written notice to Tenant (as amended from time to time,
the “Rules and Regulations”). Landlord agrees that any enforcement of the Rules and Regulations
shall be done in a reasonable, uniform and non-discriminatory manner.

     5.7 Landlord’s Contribution. (a) Landlord shall pay to Tenant an amount not to exceed
Landlord’s Contribution toward the cost of the Initial Installations, provided that as of the date
on which Landlord is required to make payment thereof pursuant to Section 5.7(b): (i) this
Lease is in full force and effect, and (ii) no Event of Default then exists. Tenant shall pay all
costs of the Initial Installations in excess of Landlord’s Contribution. Landlord’s Contribution
shall be payable solely on account of hard and soft costs associated with the development, design,
construction, installation and construction management of the Initial Improvements and move
coordination, including any reconfiguration of the existing Furniture, as such costs are identified
by Tenant with the reasonable approval of Landlord; provided, however, up to but not more than
fifty percent (50%) of the Landlord’s Contribution may be applied against the purchase of new
furniture, fixtures, equipment and signage for the Premises. Upon the occurrence of the date which
is twelve (12) months after the Lease Commencement Date, any amount of Landlord’s Contribution
which has not been previously disbursed shall be retained by Landlord and Tenant shall have no
further right or claim thereto. Any new furniture purchased by Tenant for which Landlord’s
Contribution is applied shall constitute Furniture and shall be and become the property of Landlord
and shall be surrendered to Landlord upon the expiration or earlier termination of this Lease in
accordance with Section 1.4 of this Lease.

     (b) Landlord shall make progress payments on account of Landlord’s Contribution to Tenant on
a periodic basis for completed work, but no more than once per calendar month, upon requisition
therefore by Tenant. Provided that Tenant delivers requisitions to Landlord on or prior to the
tenth day of any month, such progress payments shall be made within thirty (30) days following the
delivery to Landlord of requisitions therefor. Any requisitions made following the tenth day of
any month shall be paid no later than the last day of the month following the month in which such
requisitions are made. Each requisition shall be executed by a corporate officer or an authorized
representative of Tenant, and shall be accompanied by: (i) copies of paid invoices covering the
Initial Installations that are the subject of the requisition, (ii) a certification from Tenant’s
architect stating that (A) the Initial Installations described on such invoices have been completed
in accordance with the plans and specifications approved by Landlord, (B) such work has been paid
in full by Tenant, and (C) all contractors, subcontractors and material suppliers
have delivered to Tenant waivers of lien with respect to such work (copies of which shall be
included with such architect’s certification), (iii) proof of the satisfactory completion of all
required inspections and the issuance of a certificate of occupancy and all other required

23

 

approvals and sign-offs by Governmental Authorities, as applicable, with respect to the Initial
Installations covered by said requisition, (iv) final “as-built” plans and specifications for the
Initial Installations covered by the requisition as required pursuant to Section 8.2, (v)
final lien waivers from all contractors, subcontractors and material suppliers covering the Initial
Installations that are the subject of the requisition, and (vi) such other documents and
information as Landlord may reasonably request, including title drawdowns and endorsements. The
aggregate amount of the periodic distributions of Landlord’s Contribution shall in no event exceed
Landlord’s Contribution. The right to receive Landlord’s Contribution is for the exclusive benefit
of Tenant, and in no event shall such right be assigned to or be enforceable by or for the benefit
of any third party, including any contractor, subcontractor, materialman, laborer, architect,
engineer, attorney or other person or entity.

     (c) Landlord and Tenant acknowledge that the Initial Installations will involve a redesign of
the HVAC system for the Premises for office use. Landlord has engaged KMB Group, a third party
engineer, to evaluate Tenant’s HVAC requirements based on the information that Tenant has provided
to Landlord regarding Tenant’s Initial Installations. KMB has provided a scope of work (the “KMB
Scope of Work”) to establish fourteen (14) new HVAC zones to provide heating and cooling to the
Premises upon conversion of lab space to office space (the “HVAC Work”). Notwithstanding anything
to the contrary set forth in this Section 5.7, Landlord will pay for the cost of the HVAC
Work in addition to Landlord’s Contribution provided that the scope of the work does not change
from the KMB Scope of Work. Tenant shall perform the HVAC Work in accordance with KMB Work Scope
and agrees to use reasonable efforts to control the costs of the HVAC Work so as to minimize the
amount that Landlord will be required to pay on account of such HVAC Work. Tenant’s obligation to
use reasonable efforts shall be satisfied by (a) Tenant choosing a contractor for such HVAC Work
based on competitive bids from at least three (3) contractors approved by the Landlord, which
approval shall not be unreasonably withheld or delayed; and (b) Tenant utilizing the same measures
for cost control during performance of the HVAC Work as Tenant uses during performance of the
Initial Installations. Tenant agrees to consult with Landlord contemporaneously with Tenant’s
review of contractor bids, bid tabulation, awards and contractor contract negotiations for the HVAC
Work. In addition, the HVAC Work shall be performed on a so-called “open book” basis such that the
Landlord will have the right to inspect the bid tabulation.

     (d) Landlord and Tenant acknowledge that the Initial Installations will involve a conversion
of certain of the Lab Areas to office space. Based upon Tenant’s design of the Premises, if the
current air handler and chiller system is able to provide sufficient cooling for the remaining lab
areas in an efficient and cost-effective manner, Landlord and Tenant will work together to
establish a new allocation of the electricity expenses attributable to the chillers and air
handlers which service the remaining lab areas within the Premises from that set forth in
Section 4.7.2 of this Lease. Tenant agrees to hire a certified HVAC engineer approved by
Landlord (such approval not to be unreasonably withheld or delayed), at Tenant’s sole cost and
expense, to review Tenant’s final configuration plans for the Premises in order to determine and
certify whether the existing air handler and chiller system is able to provide sufficient cooling
for the remaining lab areas in an efficient and cost effective manner. If the engineer is unable
to certify that the current air handler and chiller system can provide sufficient cooling for the
remaining lab areas in an efficient and cost-effective manner, then Tenant shall replace the air
handler and chiller system and Tenant shall be responsible as part of the Initial Installations, at

24

 

Tenant’s sole cost and expense, subject to the provisions of Section 5.7(a), for installing
a cooling and ventilation system(s) for the remaining lab areas and installing a submeter or
checkmeter for such system(s) to enable Landlord to measure the electricity usage for such
system(s) so that Landlord can bill to Tenant one hundred percent (100%) of the electrical expenses
attributable to such new system(s). Tenant shall have the option, at its sole cost and expense and
in accordance with Article 8 of this Lease, of removing and disposing of all or part of the current
air handler and chiller system and using the existing footings, plumbing and electrical connections
of the current air handler and chiller system for the successor system(s).

ARTICLE 6

SERVICES AND UTILITIES

     6.1 Standard Tenant Services. Landlord shall maintain and operate the Building in a
manner consistent with other Comparable Buildings (as defined below), and provide ingress and
egress control services to the Building in a first-class manner consistent with the Comparable
Buildings, shall keep the Building Structure and Building Systems in first-class condition and
repair consistent with the Comparable Buildings, and all of such expenses shall be included in
Operating Expenses. (As used in this Lease, the term “Comparable Buildings” means buildings which
are comparable to the Building in terms of age, quality of construction, level of service and
amenities, size and appearance and located in a comparable geographical area, as reasonably
determined by Landlord.) During the Lease Term, Landlord shall provide the following services:

          6.1.1 Subject to limitations imposed by all governmental rules, regulations guidelines
applicable thereto, (a) from Monday through Friday from 8 a.m. to 6 p.m. (but excluding Holidays,
as defined below) (such dates and times herein called “Building Hours”), Landlord shall provide
heating and air conditioning (“HVAC”) to the office portion of the Premises, and (b) subject to
the provisions of Sections 4.7.2 and 7.1, Landlord shall provide continuous HVAC to the
“Lab Areas” designated on Exhibit A. Tenant may request and Landlord shall provide HVAC
service at times other than during Building Hours at the rate of Fifty Dollars ($50) per hour,
with a minimum charge of One Hundred Dollars ($100); provided, however, that Tenant shall only be
charged for after hours HVAC actually requested by Tenant. Landlord reserves the right reasonably
to increase the cost for after hours air conditioning in accordance with increases in Comparable
Buildings, not to exceed the increase in actual costs, including, without limitation, utility
costs and depreciation for equipment.

          6.1.2 Landlord shall provide city water from the regular Building outlets for drinking,
lavatory and toilet purposes in the Common Areas within the Building.

          6.1.3 On weekdays during the Lease Term, Landlord shall provide janitorial services to the
Premises, except the date of observation of the Holidays, in and about the Premises and window
washing services in a manner consistent with Comparable Buildings.

          6.1.4 Landlord shall provide nonexclusive, non-attended automatic passenger elevator service
for all elevators in the Building during Building Hours and, subject to closures for routine
maintenance or repair, shall have one (1) elevator available at all other times to

25

 

provide service to the Premises; provided, however, Landlord shall use reasonable efforts to schedule the timing
of such routine maintenance or repair, and shall otherwise use commercially reasonable efforts to
minimize any interference with Tenant’s Permitted Use and enjoyment of the Premises.

          6.1.5 Landlord shall provide electricity for lights and electrical outlets within the
Premises, subject to Tenant’s obligation to pay Tenant’s Electricity Charge.

     For the purposes of this Lease the term “Holiday” shall mean and refer to New Year’s Day,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day, day after Thanksgiving Day and
Christmas Day.

     6.2 Requirements of Tenant. At all times during the Lease Term, Tenant shall
cooperate with Landlord and abide by all regulations and requirements that Landlord may reasonably
prescribe and provide to Tenant in writing for the proper functioning and protection of the
Building HVAC, electrical, mechanical and plumbing systems.

     6.3 Interruption of Use. Except as expressly provided herein, Tenant agrees that
Landlord shall not be liable for damages, by abatement of Rent or otherwise, for failure to furnish
or delay in furnishing any service (including telephone and telecommunication services), or for any
diminution in the quality or quantity thereof, when such failure or delay or diminution is
occasioned, in whole or in part, by breakage, repairs, replacements, or improvements, by any
strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other
fuel at the Building or Project after reasonable effort to do so, by any riot or other dangerous
condition, emergency, accident or casualty whatsoever, by act or default of Tenant or other
parties, or by any other cause; and such failures or delays or diminution shall never be deemed to
constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve
Tenant from paying Rent or performing any of its obligations under this Lease. Furthermore,
Landlord shall not be liable under any circumstances for a loss of, or injury to, property or for
injury to, or interference with, Tenant’s business, including, without limitation, loss of profits,
however occurring, through or in connection with or incidental to a failure to furnish any of the
services or utilities as set forth in this Article 6. Landlord may comply with voluntary
controls or guidelines promulgated by any governmental entity relating to the use or conservation
of energy, water, gas, light or electricity or the reduction of automobile or other emissions
without creating any liability of Landlord to Tenant under this Lease, provided that (i) the
Premises are not thereby rendered untenantable, and (ii) the same does not materially adversely
interfere with Tenant’s Permitted Use of the Premises. Notwithstanding the foregoing, in the event
any utility services or other services provided to or appurtenant to the Premises are interrupted
for a period of more than three (3) consecutive business days, and such interruption (a) prevents
Tenant from operating in the Premises for its Permitted Use, and (b) is caused solely by the
negligent act or omission or willful misconduct of Landlord, its employees, agents and contractors
with respect to any facilities or equipment located on the Project and used in providing such
utilities to the Premises, then Tenant shall be entitled to an abatement of Rent for each day such
interruption continues beyond the initial period of three (3) consecutive business days.

ARTICLE 7

REPAIRS

     7.1 Landlord’s Obligations. Landlord shall maintain, repair and replace as necessary
the structural portions of the Building, including the foundation, floor/ceiling slabs, roof
structure, exterior walls, columns, beams and shafts (including elevator shafts) (collectively,
“Building Structure”) at its sole cost and expense. Landlord shall also maintain, repair and
replace as necessary the parking areas, sidewalks and access roads (including snow and ice
removal), landscaping, fountains, waterfalls, exterior Project signage, exterior glass and
mullions, stairs and stairwells, elevator cabs and equipment, plazas, art work, sculptures, men’s
and women’s washrooms, Building mechanical, electrical and telephone closets, and all common and
public areas and the Building security, mechanical, electrical, life safety, plumbing, sprinkler
systems and HVAC systems (collectively, the “Building Systems”) and all other Common Areas within
the Project, and the cost of such maintenance and repair shall be included in Operating Expenses.
In addition, as requested by Tenant and as Landlord reasonably deems necessary, Landlord shall
maintain, repair and replace all damaged, broken, or worn fixtures, floor covering, mechanical and
electrical systems and appurtenances (including without limitation light fixtures, light bulbs and
fans) within the Premises (subject to the provisions of Article 27 regarding Landlord’s
access to the Premises), excepting any Alterations (as defined in Article 8) or personal
property within the Premises, and excluding damage caused by Tenant (other than ordinary wear and
tear and damage covered by insurance, to the extent of such coverage) and shall include the costs
thereof in Operating Expenses. Landlord shall undertake reasonable efforts to perform all
maintenance, repairs and replacements pursuant to this Section 7.1 promptly after Landlord
learns of the need for such maintenance, repairs and replacements, but in any event within thirty
(30) days after Tenant provides written notice to Landlord of the need for such maintenance,
repairs and replacements; provided, however, that in cases of “Emergency” (i.e., circumstances
which, if not addressed promptly, could result in material damage to persons and property, and/or
damage or destruction to or of a structural component or any electrical, plumbing, mechanical or
telecommunications systems in or providing service to the Building which materially impairs
Tenant’s ability to utilize the Premises as intended for more than twenty-four (24) consecutive
hours or more than twenty-four (24) hours within any five (5) day period), Landlord shall perform
any maintenance, repairs and replacements as soon as reasonably practicable after it learns of the
need for such maintenance, repairs and replacements.

     Notwithstanding anything herein to the contrary, subject to Section 5.7(d), Tenant
shall reimburse Landlord as Additional Rent, within thirty (30) days after receipt of Landlord’s
invoice, for seventy percent (70%) of all costs paid to third parties associated with the repair,
maintenance and replacement of the air handlers and chillers which service the Lab Areas (as
defined in Section 6.1.1, above) of the Premises and such costs shall thereafter not be
included in the calculation of Operating Expenses. Notwithstanding the foregoing, with respect to
all costs for replacements of the air handlers and chillers (or components thereof) which service
the Lab Area that are capital in nature under generally accepted accounting principles, at Tenant’s
option, to be exercised within thirty (30) days after receipt of Landlord’s first invoice for such
costs, in lieu of reimbursing Landlord within thirty (30) days, such costs shall be amortized (with
interest at ten percent (10%) per annum) over the lesser of (i) the remaining Term of the Lease, or
(ii) the

27

 

useful life of the item being replaced, and Tenant shall pay Landlord, as Additional Rent, on a
monthly basis, the amortized portion and interest applicable thereto.

     In the event that Tenant is dissatisfied with the quality or cost of repairs, maintenance
and/or replacement of the air handlers and chillers which service the Lab Areas, then upon thirty
(30) days advance written notice to Landlord, Tenant may elect to repair, maintain and replace said
air handlers and chillers, in which case, Tenant shall provide Landlord with a copy of any
maintenance contract(s), and all invoices, receipts, statements, guaranties and warranties for such
repair, maintenance or replacement, and Landlord shall reimburse Tenant, within thirty (30) days
after receipt of Tenant’s invoice for thirty percent (30%) of all costs paid to third parties
associated with the repair, maintenance and replacement of said air handlers and chillers, provided
that the cost to Landlord shall in no event exceed the amount which would have been payable by
Landlord if Landlord had retained responsibility for such work.

     Notwithstanding anything to the contrary set forth in this Section 7.1, in the event
that Tenant installs a new cooling and ventilation system(s) for the reconfigured lab areas
pursuant to Section 5.7(d), Tenant shall be required to maintain, repair and replace said
cooling and ventilation system(s), at Tenant’s sole cost and expense. Provided, that Tenant has
properly maintained and repaired the cooling and ventilation system(s) in good order and repair
during the Lease Term (including any extensions thereof), Tenant shall have no obligation to remove
said cooling and ventilation system(s) at the termination or earlier expiration of the Lease.

     7.2 Tenant’s Obligations. Notwithstanding anything in this Lease to the contrary,
Tenant shall be required to repair any damage to the Building Structure and/or the Building Systems
to the extent caused due to Tenant’s use of the Premises for other than its Permitted Use, unless
and to the extent such damage is covered by insurance carried by Landlord pursuant to Article
10 and to which the waiver of subrogation is applicable. Tenant shall, at Tenant’s own
expense, pursuant to the TCCs of this Lease, including without limitation Article 8 hereof,
maintain the Furniture and all Alterations and other personal property of Tenant within the
Premises in good order, repair and condition at all times during the Lease Term. Tenant hereby
waives any and all rights to terminate this Lease, complete repairs, and offset the rent as may be
provided under the laws of the Commonwealth of Massachusetts, now or hereafter in effect.

ARTICLE 8

ADDITIONS AND ALTERATIONS

     8.1 Landlord’s Consent to Alterations. Tenant may not make any improvements,
alterations, additions or changes to the Premises or any mechanical, plumbing or HVAC facilities or
systems pertaining to the Premises which affect the Building Structure, Building Systems or
exterior appearance of the Building (collectively, the “Alterations”) without first procuring the
prior written consent of Landlord to such Alterations, which consent shall be requested by Tenant
not less than ten (10) days prior to the commencement thereof, and which consent shall not be
unreasonably withheld, conditioned or delayed by Landlord, provided it shall be deemed reasonable
for Landlord to withhold its consent to any Alteration which materially or adversely affects the
Building Structure, Building Systems or exterior appearance of the Building. Tenant shall have the
right to make interior modifications to the Premises

28

 

without Landlord’s consent provided that such alterations do not materially or adversely
affect the mechanical, electrical, plumbing or structural systems in the Building, and provided
further that Tenant shall give Landlord notice of such modifications at least ten (10) days prior
to the commencement of such modifications.

     8.2 Manner of Construction. Tenant shall utilize only competent contractors,
subcontractors, materials, mechanics and materialmen reasonably approved by Landlord for the
construction of any Alterations, which approval shall not be unreasonably withheld, conditioned or
delayed; provided, however, that Tenant shall be entitled to use its employees to make Alterations
which do not affect the mechanical or structural portions of the Premises or the Building Structure
so long as Tenant complies with all other provisions of this Article 8. Upon Landlord’s
request (unless Landlord waived, at the time of Landlord’s approval of any Alterations pursuant to
the provisions of Section 8.5, below, its right to make such request), Tenant shall, at
Tenant’s expense, remove such Alterations upon the expiration or any early termination of the
Lease. If such Alterations will involve the use of or disturb Hazardous Materials or substances
existing in the Premises, Tenant shall comply with Landlord’s rules and regulations concerning, and
all Applicable Laws pertaining to, Hazardous Materials or substances with respect to such
Alterations. Tenant shall construct such Alterations and perform such repairs in a good and
workmanlike manner, in conformance with any and all applicable federal, commonwealth, county or
municipal laws, rules and regulations and pursuant to a valid building permit, issued by the City
of Marlborough, and in conformance with Landlord’s construction rules and regulations, if any,
provided to Tenant in writing prior to construction of such Alterations. In the event Tenant
performs any Alterations in the Premises which require or give rise to governmentally required
changes to the “Base Building,” as that term is defined below, then Landlord shall, at Tenant’s
expense, make such changes to the Base Building. The “Base Building” shall include the Building
Structure, and the public restrooms and the systems and equipment located in the internal core of
the Building on the floor or floors on which the Premises are located. In performing the work of
any such Alterations, Tenant shall have the work performed in such manner so as not to obstruct
access to the Building, the Project or any portion thereof, by any other tenant of the Building or
the Project, and so as not to obstruct the business of Landlord or other tenants in the Building or
Project. Tenant shall not use (and promptly after notice from Landlord shall cease using)
contractors, services, workmen, labor, materials or equipment that, in Landlord’s reasonable
judgment, would disturb labor harmony with the workforce or trades engaged in performing other
work, labor or services in or about the Building or the Common Areas. In addition to Tenant’s
obligations under Article 9 of this Lease, upon completion of the Initial Installations or
any Alterations which affect the Building Systems and Building Structures, Tenant agrees to cause
such notices as may be necessary to evidence completion of any work undertaken by Tenant to be
recorded in the office of the Recorder of the County of Middlesex in accordance with the laws of
the Commonwealth of Massachusetts or any successor statute, and Tenant shall deliver to the Project
management office a reproducible copy of the “as built” drawings of the Alterations as well as all
permits, approvals and other documents issued by any governmental agency in connection with the
Alterations.

     8.3 Payment for Improvements. If payment is made directly to contractors, Tenant
shall comply with all Applicable Laws relating to final lien releases and waivers in connection
with Tenant’s payment for work to contractors. Whether or not Tenant orders any work directly

29

 

from Landlord, Tenant shall reimburse Landlord for Landlord’s reasonable out-of-pocket costs
and expenses reasonably incurred in connection with Landlord’s review of any Alterations (other
than the Initial Installations), not to exceed One Thousand Dollars ($1,000).

     8.4 Construction Insurance. In addition to the requirements of Article 10 of
this Lease, in the event that Tenant makes any Alterations, prior to the commencement of such
Alterations, Tenant shall provide Landlord with evidence that Tenant carries “Builder’s All Risk”
insurance in an amount reasonably related to the value of such Alterations, it being understood and
agreed that all of such Alterations shall be insured by Tenant pursuant to Article 10 of
this Lease immediately upon completion thereof.

     8.5 Landlord’s Property. All Alterations, improvements, fixtures, equipment and/or
appurtenances other than Tenant’s trade fixtures and equipment which may be installed or placed in
or about the Premises, from time to time, shall be and become the property of Landlord upon the
expiration of this Lease, subject to the requirements of Section 8.2 and Landlord’s right
to require Tenant to remove such items as provided in this Section 8.5. Upon the
expiration or earlier termination of this Lease, Tenant may remove any equipment or fixtures
installed by Tenant, provided Tenant repairs any damage to the Premises and Building caused by such
removal and returns the affected portion of the Premises to Building Standard condition.
Furthermore, Landlord may, by written notice to Tenant prior to the end of the Lease Term, or given
following any earlier termination of this Lease, require Tenant, at Tenant’s expense, to remove any
Alterations in the Premises and to repair any damage to the Premises and Building caused by such
removal (reasonable wear and tear excepted) and return the affected portion of the Premises to
Building Standard condition; provided, however, if, in connection with its request for Landlord’s
approval for particular Alterations, (1) Tenant requests Landlord’s decision with regard to the
removal of such Alterations, and (2) Landlord thereafter agrees in writing to waive the removal
requirement when approving such Alterations, then Tenant shall not be required to so remove such
Alterations; provided further, however, that if Tenant requests such a determination from Landlord
and Landlord, in its approval of any Alterations, fails to address the removal requirement with
regard to such Alterations, Landlord shall be deemed to have agreed to waive the removal
requirement with regard to such Alterations. If Tenant fails to complete such removal and/or to
repair any damage caused by the removal of any Alterations in the Premises and return the affected
portion of the Premises to Building Standard condition, then, after written notice and a reasonable
period in which to complete such removal and repairs, Landlord may do so and may charge the cost
thereof to Tenant, and Tenant shall reimburse Landlord for such costs within ten (10) days after
receipt of Landlord’s invoice therefore. Tenant hereby protects, defends, indemnifies and holds
Landlord harmless from any liability, cost, obligation, expense or claim of lien in any manner
relating to the Tenant’s installation, placement, removal or financing of any such Alterations,
improvements, fixtures and/or equipment in, on or about the Premises, which obligations of Tenant
shall survive the expiration or earlier termination of this Lease for one (1) year following such
expiration or earlier termination. At all times during the Term of this Lease, Tenant shall be
entitled to remove, and Landlord shall have no interest in, Tenant’s trade fixtures, equipment and
other personal property in the Premises.

30

 

ARTICLE 9

COVENANT AGAINST LIENS

     Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of
the work performed, materials furnished or obligations incurred by or on behalf of Tenant by agents
other than Landlord or agents working at the request and under direction of Landlord, and shall
protect, defend, indemnify and hold Landlord harmless from and against any claims, liabilities,
judgments or costs (including, without limitation, reasonable attorneys’ fees and costs) arising
out of same or in connection therewith. Tenant shall give Landlord notice at least ten (10)
business days prior to the commencement of any such work on the Premises (or such additional time
as may be necessary under Applicable Laws) to afford Landlord the opportunity of posting and
recording appropriate notices of non-responsibility. Tenant shall remove any such lien or
encumbrance by bond or otherwise within ten (10) business days after notice by Landlord, and if
Tenant shall fail to do so, Landlord may pay the amount necessary to remove such lien or
encumbrance, without being responsible for investigating the validity thereof. The amount so paid
shall be deemed Additional Rent under this Lease payable upon demand, without limitation as to
other remedies available to Landlord under this Lease. Nothing contained in this Lease shall
authorize Tenant to do any act which shall subject Landlord’s title to the Building or Premises to
any liens or encumbrances whether claimed by operation of law or express or implied contract.

ARTICLE 10

INSURANCE

     10.1 Indemnification and Waiver. Tenant hereby assumes all risk of damage to property
or injury to persons in, upon or about the Premises from any cause whatsoever and agrees that
Landlord, its partners, subpartners and their respective officers, agents, servants, employees, and
independent contractors (collectively, “Landlord Parties”) shall not be liable for, and are hereby
released from any responsibility for, any damage either to person or property or resulting from the
loss of use thereof, which damage is sustained by Tenant or by other persons claiming through
Tenant, except to the extent such damage results from the negligent acts or omissions or willful
misconduct of Landlord, its agents, employees and contractors or from Landlord’s failure to perform
its obligations under this Lease, and in such event, only to the extent not covered by Tenant’s
insurance required to be carried hereunder. Tenant shall indemnify, defend, protect, and hold
harmless the Landlord Parties from any and all loss, cost, damage, expense and liability (including
without limitation court costs and reasonable attorneys’ fees) incurred in connection with or
arising from any cause in the Premises, and to the extent arising from the negligent act or
omission of Tenant or of any person claiming by, through or under Tenant, or of the contractors,
agents, servants, employees, invitees, guests or licensees of Tenant or any such person, in, on or
about the Project, either prior to, during, or after the expiration or earlier termination of the
Lease, except to the extent such damage results from the negligent acts or omissions or willful
misconduct of Landlord, its agents, employees and contractors or from Landlord’s failure to perform
its obligations under this Lease, and in such event, only to the extent not covered by Landlord’s
insurance required to be carried hereunder. Landlord shall indemnify, defend, protect, and hold
harmless Tenant and its officers, agents,

31

 

employees and contractors from any and all loss, cost damage, expense and liability (including
without limitation court costs and reasonable attorneys’ fees) to the extent arising from the
negligent acts or omissions or willful misconduct of Landlord, its agents, employees and
contractors in, on or about the Project, either prior to, during, or after the expiration or
earlier termination of the Lease except to the extent such damage results from the negligent acts
or omissions or willful misconduct of Tenant, its agents, employees and contractors or from
Tenant’s failure to perform its obligations under this Lease, and in such event, only to the extent
not covered by Landlord’s insurance required to be carried hereunder. Further, Landlord’s and
Tenant’s agreements to indemnify pursuant to this Section 10.1 are not intended and shall
not relieve any insurance carrier of its obligations, to the extent such policies cover the matters
subject to the foregoing indemnification obligations; nor shall they supersede any inconsistent
agreement of the parties set forth in any other provision of this Lease. The provisions of this
Section 10.1 shall survive the expiration or sooner termination of this Lease with respect
to any claims or liability arising in connection with any event occurring prior to such expiration
or termination.

     10.2 Tenant’s Compliance With Landlord’s Fire and Casualty Insurance. Tenant shall,
at Tenant’s expense, comply with all insurance company requirements pertaining to the use of the
Premises to the extent such requirements are provided by Landlord to Tenant in writing. If
Tenant’s conduct or use of the Premises causes any increase in the premium for such insurance
policies then Tenant shall reimburse Landlord for any such increase within fifteen (15) business
days after receipt of Landlord’s written demand; provided, however, that Landlord shall provide
reasonably sufficient documentation or other evidence to Tenant that its use and occupancy of the
Premises caused such increase in connection with any demand for payment. Tenant, at Tenant’s
expense, shall comply with all rules, orders, regulations or requirements of the American Insurance
Association (formerly the National Board of Fire Underwriters) and with any similar body.

     10.3 Tenant’s Insurance. Tenant shall maintain the following coverages in the
following amounts.

          10.3.1 Commercial General Liability Insurance covering the insured against claims of bodily
injury, personal injury and property damage (including loss of use thereof) arising out of
Tenant’s operations, and contractual liabilities (covering the performance by Tenant of its
indemnity agreements) including the equivalent of the coverage provided by a Broad Form
endorsement covering the insuring provisions of this Lease and the performance by Tenant of the
indemnity agreements set forth in Section 10.1 of this Lease, for limits of liability not
less than:

	 	 	 
	Bodily Injury and

	 	$5,000,000 each occurrence
	Property Damage Liability

	 	$5,000,000 annual aggregate
	 
	 	 
	Personal Injury Liability

	 	$5,000,000 each occurrence
	 

	 	$5,000,000 annual aggregate

32

 

          10.3.2 Physical Damage Insurance covering any Alterations made to the Premises in accordance
with Article 8 of this Lease and property insurance covering the Furniture and Tenant’s
personal property, trade fixtures and equipment in the Premises at one hundred percent (100%)
replacement cost. Such insurance shall be written on an “all risks” of physical loss or damage
basis, for the full replacement cost value (subject to reasonable deductible amounts) new without
deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses
of the policies of insurance and shall include coverage for damage or other loss caused by fire or
other peril including, but not limited to, vandalism and malicious mischief, theft, water damage
of any type, including sprinkler leakage, bursting or stoppage of pipes, and explosion.

          10.3.3 Worker’s Compensation and Employer’s Liability or other similar insurance pursuant to
all applicable commonwealth, state and local statutes and regulations.

     10.4 Form of Policies. The minimum limits of policies of insurance required of Tenant
under this Lease shall in no event limit the liability of Tenant under this Lease. Tenant’s
liability insurance shall (i) name Landlord, Landlord’s lender and Landlord’s managing agent, if
any, as an additional insured; (ii) specifically cover the liability assumed by Tenant under this
Lease, including, but not limited to, Tenant’s obligations under Section 10.1 of this
Lease; (iii) be issued by an insurance company having a rating of not less than A-VII in Best’s
Insurance Guide and licensed to do business in the Commonwealth of Massachusetts; (iv) be primary
insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess
and is non-contributing with any insurance requirement of Tenant; and (v) provide that Tenant’s
insurance carrier shall endeavor to give Landlord ten (10) days’ written notice prior to such
insurance being canceled or coverage reduced. Tenant shall deliver evidence of such coverage to
Landlord on or before the Lease Commencement Date and at the time of any renewal thereof. In the
event Tenant shall fail to procure such insurance, or to deliver such evidence, including a
certificate of insurance, Landlord may, at its option, if Tenant fails to provide evidence of such
insurance within five (5) business days after notice from Landlord, procure such policies for the
account of Tenant, and the cost thereof shall be paid to Landlord within five (5) business days
after delivery to Tenant of bills therefor.

     10.5 Subrogation. Landlord and Tenant shall cause their insurers to waive all rights
of subrogation in their respective insurance policies during the Lease Term. The parties agree
that their respective insurance policies, which include a waiver of subrogation provision, shall
not affect the right of the insured to recover thereunder, and no additional premium is charged
therefor.

     10.6 Landlord’s Insurance. Landlord shall insure the Building (including the Building
Structure and Building Systems), the Furniture and the Project during the Lease Term against loss
or damage due to fire and other casualties covered within the classification of fire and extended
coverage at the full replacement cost of the Buildings and other improvements which constitute the
Project (excluding footings and foundations). Such coverage shall be in such amounts, from such
companies, and on such other terms and conditions, as Landlord may from time to time reasonably
determine, consistent with the practices of landlords of Comparable Buildings, with a deductible
not to exceed Two Hundred and Fifty Thousand Dollars ($250,000) per occurrence. Additionally, at
the sole option of Landlord, such insurance coverage may

33

 

include the risk of flood damage and additional hazards, a rental loss endorsement and one (1)
or more loss payee endorsements in favor of the holders of any mortgages or deeds of trust
encumbering the interest of Landlord in the Building or the ground or underlying lessors of the
Building, or any portion thereof. Landlord shall maintain a Commercial General Liability Insurance
policy covering the insured against claims of bodily injury and personal injury, for limits of
liability not initially less than $5,000,000 each occurrence and $5,000,000 annual aggregate for
each of bodily injury and personal injury.

ARTICLE 11

DAMAGE AND DESTRUCTION

     11.1 Repair of Damage by Landlord. Tenant shall promptly notify Landlord of any
damage to, or affecting, the Premises resulting from fire or any other casualty. If the Premises,
the Building or any Common Areas serving or providing access to the Premises shall be damaged by
fire or other casualty, Landlord shall promptly and diligently, subject to reasonable delays for
insurance adjustment or other delays due to Force Majeure, and subject to all other TCCs of this
Article 11, restore the Premises, the Building and such Common Areas. Such restoration
shall be to substantially the same condition as existed prior to the casualty, except for
modifications required by zoning and building codes and other laws, provided that access to the
Premises and any common restrooms serving the Premises and Tenant’s use of the Premises shall not
be materially impaired. Within sixty (60) days after the occurrence of such fire or other
casualty, Landlord shall provide Tenant with a statement setting forth the time within which
Landlord expects such restoration to be substantially completed. Upon the occurrence of any damage
to the Furniture, Landlord shall replace the Furniture to the extent of such insurance proceeds or,
if this Lease is terminated as a result of such casualty, Landlord shall retain such proceeds.
Upon notice to Tenant from Landlord, and provided this Lease has not terminated as provided in this
Article 11, Tenant shall proceed to restore and repair any injury or damage to any
Alterations which have been completed or installed by or on behalf of Tenant in the Premises after
the Lease Commencement Date and which will be retained by Landlord upon the expiration or earlier
termination of this Lease. Tenant shall restore such Alterations to substantially the same
condition as existed immediately prior to the casualty, but Tenant shall otherwise have no
obligation to restore any other Alterations, equipment or trade fixtures within the Premises.
Prior to the commencement of any restoration work in the Premises, Tenant shall submit to Landlord,
for Landlord’s review and approval, all plans, specifications and working drawings relating
thereto, and Landlord shall approve such plans and specifications and Tenant’s contractors to be
used for such work pursuant to the provisions of Article 8. Landlord shall not be liable
for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business
resulting in any way from such damage or the repair thereof; provided however, that if such fire or
other casualty shall have damaged the Premises or Common Areas necessary to Tenant’s occupancy,
Landlord shall allow Tenant a proportionate abatement of Rent to the extent Tenant is unable to
operate its business in the Premises (measured by the proportion of square feet of the Premises in
which Tenant is unable to operate as compared to the total size of the Premises, and continuing
until such time as such areas are restored substantially to their condition prior to the casualty),
regardless of whether Landlord is reimbursed from the proceeds of rental interruption insurance
purchased or required to be purchased by Landlord as part of Operating Expenses, during the time
and to the extent the Premises are unfit for occupancy for

34

 

the purposes permitted under this Lease, and not occupied by Tenant as a result thereof;
provided, further, however, that if the damage or destruction is due to the negligence or
intentional misconduct of Tenant, Tenant shall be responsible for any reasonable, applicable
insurance deductible (which shall be payable to Landlord upon demand).

     11.2 Landlord’s Option to Repair. Notwithstanding the TCCs of Section 11.1 of
this Lease, Landlord may elect not to rebuild and/or restore the Premises, Building and/or Project,
and instead terminate this Lease (or the applicable portion thereof), by notifying Tenant in
writing of such termination within sixty (60) days after the date of discovery of the damage, such
notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but
Landlord may so elect only if the Building or Project shall be damaged by fire or other casualty or
cause, if one (1) or more of the following conditions is present: (i) in Landlord’s reasonable
judgment, repairs cannot reasonably be completed within twelve (12) months after the date of
discovery of the damage (when such repairs are made without the payment of overtime or other
premiums) (provided, however, if the repair of Building 2 can be completed within twelve (12)
months, Landlord may not terminate this Lease merely because the repair of other portions of the
Project cannot be completed within said period) ; (ii) the damage is not fully covered by
Landlord’s insurance policies (except with regard to any applicable deductibles); (iii) the damage
occurs during the last twelve (12) months of the Lease Term; or (iv) Landlord’s mortgagee does not
permit the insurance proceeds to be applied to the rebuilding or repair of the Building or Project.
If Landlord delivers a termination notice based on the insufficiency of Landlord’s insurance
proceeds, Landlord shall provide documentation for the shortfall in insurance proceeds as compared
to Landlord’s repair estimates, and Tenant shall be entitled, at its sole discretion, to void
Landlord’s termination notice by agreeing to pay the excess repair and restoration expenses by
providing written notice of such election within thirty (30) days after receipt of Landlord’s
termination notice. If Landlord does not elect to terminate this Lease pursuant to Landlord’s
termination right as provided above, and if the repairs to be made by Landlord are not actually
completed within twelve (12) months after the date of discovery of the damage, which period may be
extended up to two (2) additional months for Force Majeure delays and/or delays in insurance
adjustment as reasonably demonstrated by Landlord to Tenant), Tenant shall have the right to
terminate this Lease by providing written notice to Landlord (the “Damage Termination Notice”),
such termination to be effective five (5) business days after Landlord’s receipt of the Damage
Termination Notice (the “Damage Termination Date”); provided, however, that Landlord shall have the
right to suspend the occurrence of the Damage Termination Date for a period of thirty (30) days
after the Damage Termination Date by delivering to Tenant, on or before the Damage Termination
Date, a certificate of Landlord’s contractor responsible for the repair of the damage certifying
that it is such contractor’s good faith judgment that the repairs to be made by Landlord shall be
completed within thirty (30) days after the Damage Termination Date. If such repairs shall be
completed prior to the expiration of such thirty (30)day period, then the Damage Termination Notice
shall be of no force or effect, but if such repairs shall not be completed within such thirty (30)
day period, then this Lease shall terminate upon the expiration of such thirty (30) day period.

     11.3 Tenant’s Option to Terminate In the event that the damage or destruction to the
Premises from fire or other casualty either (i) will, in Landlord’s reasonable judgment take more
than twelve (12) months to repair, or (ii) takes place during the last twelve (12) months of the
Lease Term and such damage cannot reasonably be repaired within ninety (90) days after the

35

 

date of such damage, Tenant shall have the option, to be exercised by written notice given to
Landlord within twenty (20) days after the date of the damage, to terminate this Lease effective as
of the date of said notice or such later date as shall be specified in Tenant’s notice of
termination.

     11.4 Waiver of Statutory Provisions. The provisions of this Lease, including this
Article 11, constitute an express agreement between Landlord and Tenant with respect to any
and all damage to, or destruction of, all or any part of the Premises, the Building or the Project,
and any statute or regulation of the Commonwealth of Massachusetts, with respect to any rights or
obligations concerning damage or destruction in the absence of an express agreement between the
parties, and any other statute or regulation, now or hereafter in effect, shall have no application
to this Lease or any damage or destruction to all or any part of the Premises, the Building or the
Project.

ARTICLE 12

NON-WAIVER

     No provision of this Lease shall be deemed waived by either party hereto unless expressly
waived in a writing signed thereby. The waiver by either party hereto of any breach of any term,
covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach
of same or any other term, covenant or condition herein contained. The subsequent acceptance of
Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of
any term, covenant or condition of this Lease, other than the failure of Tenant to pay the
particular Rent so accepted, regardless of Landlord’s knowledge of such preceding breach at the
time of acceptance of such Rent. No acceptance of a lesser amount than the Rent herein stipulated
shall be deemed a waiver of Landlord’s right to receive the full amount due, nor shall any
endorsement or statement on any check or payment or any letter accompanying such check or payment
be deemed an accord and satisfaction, and Landlord may accept such check or payment without
prejudice to Landlord’s right to recover the full amount due. No receipt of monies by Landlord
from Tenant after the termination of this Lease shall in any way alter the length of the Lease Term
or of Tenant’s right of possession hereunder, or after the giving of any notice shall reinstate,
continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such
monies, it being agreed that after the service of notice or the commencement of a suit, or after
final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and
the payment of said Rent shall not waive or affect said notice, suit or judgment.

ARTICLE 13

CONDEMNATION

     13.1 Condemnation. If the whole or any part of the Premises, Building or Project
shall be taken by power of eminent domain or condemned by any competent authority for any public or
quasi-public use or purpose, or if any adjacent property or street shall be so taken or condemned,
or reconfigured or vacated by such authority in such manner as to require the use, reconstruction
or remodeling of any part of the Premises, Building or Project, and if as a result

36

 

thereof Tenant cannot conduct its business operations in substantially the same manner such
business operations were conducted prior to such taking while still retaining substantially the
same material rights and benefits it bargained to receive under this Lease, or if Landlord shall
grant a deed or other instrument in lieu of such taking by eminent domain or condemnation as a
result thereof, Landlord and Tenant shall each have the option to terminate this Lease on ninety
(90) days notice to the other party effective as of the date possession is required to be
surrendered to the authority. Subject to Section 13.2 below, Tenant shall not because of
such taking assert any claim against Landlord or the authority for any compensation because of such
taking and Landlord shall be entitled to the entire award or payment in connection therewith,
except that Tenant shall have the right to file any separate claim available to Tenant for any
taking of Tenant’s personal property and fixtures belonging to Tenant and removable by Tenant upon
expiration of the Lease Term pursuant to the TCCs of this Lease, and for moving expenses, so long
as such claims do not diminish the award available to Landlord or its ground lessor, if any, with
respect to the Building or Project, or its mortgagee, and such claim is payable separately to
Tenant. All Rent shall be apportioned as of the date of such termination. If any part of the
Premises shall be taken, and this Lease shall not be so terminated, the Rent shall be
proportionately abated. Notwithstanding anything to the contrary contained in this Article
13, in the event of a temporary taking of all or any portion of the Premises for a period of
sixty (60) days or less, then this Lease shall not terminate but the Base Rent and the Additional
Rent shall be abated for the period of such taking in proportion to the ratio that the amount of
rentable square feet of the Premises taken bears to the total rentable square feet of the Premises.
Subject to Section 13.2 below, Landlord shall be entitled to receive the entire award made
in connection with any such temporary taking. Landlord and Tenant hereby waive the provisions of
any statutes or other laws relating to the termination of leases in the event of condemnation, and
agree that the rights and obligations of the parties in such event shall be governed by the terms
of this Lease.

     13.2 Tenant’s Right to Award. Subject to the provisions of Section 13.1
above, Tenant shall have the right to claim and recover (i) the fair market value of the
Alterations to the extent paid for solely by Tenant, (ii) any sum awarded to Tenant for damages to
or loss of Tenant’s business, and (iii) such compensation as may be separately awarded or
recoverable by Tenant on account of any and all costs or losses related to removing Tenant’s
merchandise, furniture, fixtures, leasehold improvements, and equipment to a new location.

ARTICLE 14

ASSIGNMENT AND SUBLETTING

     14.1 Transfers. Tenant shall not: (A) mortgage, pledge, hypothecate, encumber, or
permit any lien to attach to this Lease or any interest hereunder without the prior written consent
of Landlord, which consent shall not be unreasonably withheld; nor (B) without the prior written
consent (except as otherwise provided in Section 14.7, below) of Landlord, which consent
will not be unreasonably withheld, conditioned or delayed, assign, or otherwise transfer, this
Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any
interest hereunder by operation of law, sublet the Premises or any part thereof, or enter into any
license or concession agreements or otherwise permit the occupancy or use of the Premises or any
part thereof by any persons other than Tenant and its employees and contractors; (all of the
foregoing

37

 

(in Subsection 14.1 (A) and (B)) are hereinafter sometimes referred to collectively as
“Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter
sometimes referred to as a “Transferee”). If Tenant desires Landlord’s consent to any Transfer,
Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the
proposed effective date of the Transfer, which shall not be less than twenty (20) days nor more
than sixty (60) days after the date of delivery of the Transfer Notice, (ii) a description of the
portion of the Premises to be transferred (the “Subject Space”), (iii) all of the TCCs of the
proposed Transfer and the consideration therefor, including calculation of the “Transfer Premium,”
as that term is defined in Section 14.3 below, in connection with such Transfer, (iv) the
name and address of the proposed Transferee, and a copy of all existing executed and/or proposed
documentation pertaining to the proposed Transfer, including all existing operative documents to be
executed to evidence such Transfer or the agreements incidental or related to such Transfer, (v)
current financial statements of the proposed Transferee certified by an officer, partner or owner
thereof, business credit and personal references and history of the proposed Transferee and any
other information required by Landlord which will enable Landlord to determine the financial
responsibility, character, and reputation of the proposed Transferee, nature of such Transferee’s
business and proposed use of the Subject Space and (vi) an executed estoppel certificate from
Tenant in the form attached hereto as Exhibit E-1. Any Transfer made without Landlord’s
prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at
Landlord’s option, constitute a default by Tenant under this Lease. Whether or not Landlord
consents to any proposed Transfer, Tenant shall, within thirty (30) days after written request by
Landlord, reimburse Landlord for all reasonable and actual out-of-pocket third-party costs and
expenses incurred by Landlord in connection with its review of a proposed Transfer; provided that
such costs and expenses shall not exceed One Thousand Dollars ($1,000) for a Transfer in the
ordinary course of business.

     14.2 Landlord’s Consent. Landlord shall not unreasonably withhold, condition or delay
its consent to any proposed Transfer under Subsection 14.1(B) of the Subject Space to the
Transferee on the terms specified in the Transfer Notice. Without limitation as to other
reasonable grounds for withholding consent, the parties hereby agree that it shall be reasonable
under this Lease and under any Applicable Law for Landlord to withhold consent to any proposed
Transfer where one (1) or more of the following apply:

          14.2.1 Landlord reasonably determines that the Transferee is of a character or reputation or
engaged in a business which is not consistent with the quality of the Building or the Project;

          14.2.2 The Transferee intends to use the Subject Space for purposes which are not permitted
under this Lease;

          14.2.3 The Transferee is either a governmental agency or instrumentality thereof;

          14.2.4 Tenant has defaulted in the payment of rent (beyond applicable notice and cure
provisions) more than three times in the prior twelve (12) month period;

38

 

               14.2.5 Landlord reasonably determines that the Transferee’s financial worth and/or financial
stability is insufficient to meet the proposed financial obligations on the date consent is
requested;

               14.2.6 The Transferee is an existing tenant of the Project and Landlord has other comparable
space available in the Project;

               14.2.7 The parking requirements of the Transferee are in excess of the proportionate share of
parking which would be allocable to the Subject Space based on the rentable square footage of the
Subject Space compared to the total rentable square footage of the Project;

               14.2.8 There is an uncured Event of Default under the Lease (beyond any applicable notice and
cure provisions).

          If Landlord consents to any Transfer pursuant to the TCCs of this Section 14.2 (and
does not exercise any Landlord’s Option (as defined in Section 14.4, below) Landlord may
have under Section 14.4 of this Lease), Tenant may within one (1) month after Landlord’s
consent, but not later than the expiration of said one (1) month period, enter into such Transfer
of the Premises or portion thereof, upon substantially the same terms and conditions as are set
form in the Transfer Notice furnished by Tenant to Landlord pursuant to Section 14.1 of
this Lease, provided that if there are any material changes in the terms and conditions from those
specified in the Transfer Notice (i) such that Landlord would initially have been entitled to
refuse its consent to such Transfer under this Section 14.2, or (ii) which would cause the
proposed Transfer to be materially more favorable to the Transferee than the terms set forth in
Tenant’s original Transfer Notice, Tenant shall again submit the Transfer to Landlord for its
approval and other action under this Article 14 (including Landlord’s Option rights, if
any, under Section 14.4 of this Lease). Notwithstanding anything to the contrary in this
Lease, if Tenant or any proposed Transferee claims that Landlord has unreasonably withheld or
delayed its consent under Section 14.2 or otherwise has breached or acted unreasonably
under this Article 14, their remedies shall be restricted to a declaratory judgment and an
injunction for the relief sought, and shall exclude money damages. Tenant shall indemnify, defend
and hold harmless Landlord from any and all liability, losses, claims, damages, costs, expenses,
causes of action and proceedings involving any third party or parties (including without limitation
Tenant’s proposed subtenant or assignee) who claim they were damaged by Landlord’s wrongful
withholding or conditioning of Landlord’s consent.

          14.3 Transfer Premium. If Landlord consents to a Transfer, as a condition thereto
which the parties hereby agree is reasonable, Tenant shall pay to Landlord fifty percent (50%) of
any “Transfer Premium,” as that term is defined in this Section 14.3, received by Tenant
from such Transferee. “Transfer Premium” shall mean all rent, additional rent or other
consideration payable by such Transferee in connection with the Transfer in excess of the Rent and
Additional Rent payable by Tenant under this Lease during the term of the Transfer on a per
rentable square
foot basis if less than all of the Premises is transferred, after deducting all expenses
incurred by Tenant (i) in making any changes, alterations and improvements to the Premises in
connection with the Transfer, (ii) any free base rent provided to the Transferee, and (iii) any
brokerage commissions in connection with the Transfer. “Transfer Premium” shall also include, but
not be

39

 

limited to, bonus money or other cash consideration paid by Transferee to Tenant in
connection with such Transfer, and any payment in excess of fair market value for services rendered
by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by
Tenant to Transferee in connection with such Transfer. In the calculations of the Rent (as it
relates to the Transfer Premium calculated under this Section 14.3), and the Transferee’s
Rent, the Rent paid during each annual period for the Subject Space, and the Transferee’s Rent
shall be computed after adjusting such rent to the actual effective rent to be paid, taking into
consideration any and all leasehold concessions granted in connection therewith, including, but not
limited to, any rent credit and tenant improvement allowance. For purposes of calculating any such
effective rent all such concessions shall be amortized on a straight-line basis over the relevant
term.

          14.4 Landlord’s Option as to Subject Space.

               14.4.1 Assignments. In the event that a proposed Transfer, if consented to, would
cause this Lease to be assigned to a party other than Original Tenant and/or its Affiliates, then
notwithstanding anything to the contrary contained in this Article 14, Landlord shall have
the option (“Landlord’s Recapture Option”), by giving written notice to Tenant (the “Landlord
Recapture Notice”) within thirty (30) days after receipt of any Transfer Notice, to recapture the
Subject Space. In such case, the Landlord Recapture Notice shall cancel and terminate this Lease
with respect to the Subject Space as of the date stated in the Transfer Notice (or at Landlord’s
option, shall cause the Transfer to be made to Landlord or its agent, in which case the parties
shall execute the Transfer documentation promptly thereafter). In the event of a recapture by
Landlord, if this Lease shall be canceled with respect to less than the entire Premises, the Rent
reserved herein shall be prorated on the basis of the number of rentable square feet retained by
Tenant in proportion to the number of rentable square feet contained in the Premises, and this
Lease as so amended shall continue thereafter in full force and effect, and upon request of either
party, the parties shall execute written confirmation of the same. If Landlord declines, or fails
to elect in a timely manner to recapture the Subject Space under this Section 14.4, then,
provided Landlord has consented to the proposed Transfer, Tenant shall be entitled to proceed to
transfer the Subject Space to the proposed Transferee, subject to provisions of this
Article 14. As used in this Article 14, “Original Tenant” shall mean 3Com
Corporation.

               14.4.2 Subleases. In the event that a proposed Transfer, if consented to, would
cause more than two (2) floors, or fifty-five percent (55%) or more of the Premises to be
subleased to a party other than Original Tenant and/or its Affiliates, then notwithstanding
anything to the contrary contained in this Article 14, Landlord shall have the option
(“Landlord’s Option”), by giving written notice to Tenant (the “Landlord Option Notice”) within
thirty (30) days after receipt of any Transfer Notice, to sublease the Subject Space to Landlord,
or Landlord’s nominee or assignee, subject to the terms set forth in the Transfer Notice, in which
case the parties shall execute the Transfer documentation promptly thereafter. If Landlord
declines, or fails to elect in a timely manner to sublease the Subject Space under
this Section 14.4, then, provided Landlord has consented to the proposed Transfer,
Tenant shall be entitled to proceed to transfer the Subject Space to the proposed Transferee,
subject to provisions of this Article 14.

40

 

          14.5 Effect of Transfer. If Landlord consents to a Transfer, (i) the TCCs of this
Lease shall in no way be deemed to have been waived or modified, (ii) such consent shall not be
deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver
to Landlord, promptly after execution, an original executed copy of all documentation pertaining to
the Transfer, and (iv) no Transfer relating to this Lease or agreement entered into with respect
thereto, whether with or without Landlord’s consent, shall relieve Tenant from any liability under
this Lease, including, without limitation, in connection with the Subject Space. Landlord or its
authorized representatives shall have the right at all reasonable times and upon reasonable prior
notice to audit the books, records and papers of Tenant relating to any Transfer, and shall have
the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found
understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if
understated by more than five percent (5%), Tenant shall pay Landlord’s costs of such audit.

          14.6 Occurrence of Default. Any Transfer hereunder shall be subordinate and subject
to the provisions of this Lease, and if this Lease shall be terminated during the term of any
Transfer, Landlord shall have the right to: (i) treat such Transfer as cancelled and repossess the
Subject Space by any lawful means, or (ii) require that such Transferee attorn to and recognize
Landlord as its landlord under any such Transfer. If Tenant shall be in default under this Lease,
Landlord is hereby authorized to direct any Transferee to make all payments under or in connection
with the Transfer directly to Landlord (which Landlord shall apply towards Tenant’s obligations
under this Lease) until such default is cured. Such Transferee shall rely on any representation by
Landlord that Tenant is in default hereunder, without any need for confirmation thereof by Tenant.
Upon any assignment, the assignee shall assume in writing all obligations and covenants of Tenant
thereafter to be performed or observed under this Lease. No collection or acceptance of rent by
Landlord from any Transferee shall be deemed a waiver of any provision of this Article 14
or the approval of any Transferee or a release of Tenant from any obligation under this Lease,
whether theretofore or thereafter accruing. In no event shall Landlord’s enforcement of any
provision of this Lease against any Transferee be deemed a waiver of Landlord’s right to enforce
any term of this Lease against Tenant or any other person.

          14.7 Non-Transfers. Notwithstanding anything to the contrary contained in this
Article 14, an assignment or subletting of all or a portion of the Premises to any entity
which is controlled directly or indirectly by Tenant, or which entity controls, directly or
indirectly, Tenant (in each such case, an “Affiliate”), or any entity which owns or is owned by an
Affiliate, or any assignment by operation of law or otherwise resulting from any merger or
consolidation of Tenant or to any entity which purchases all or substantially all the stock or
assets of Tenant, shall not be deemed a Transfer under this Article 14, provided that at
least thirty (30) days prior to such assignment or sublease (i) Tenant notifies Landlord of any
such assignment or sublease and certified that the applicable Transfer is to an Affiliate; and (ii)
such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this
Lease. In the event an assignment or sublease to an Affiliate is made pursuant to the TCCs of this
Section 14.7, Tenant shall not be relieved of its obligations under this Lease. “Control,”
as used in this Section 14.7, shall mean
the possession, directly or indirectly, of the power to direct or cause the direction of the
management and policies of a person or entity, whether by ownership of voting securities, by
contract or otherwise.

41

 

ARTICLE 15

SURRENDER OF PREMISES; OWNERSHIP AND

REMOVAL OF TRADE FIXTURES

          15.1 Surrender of Premises. No act or thing done by Landlord or any agent or employee
of Landlord during the Lease Term shall be deemed to constitute an acceptance by Landlord of a
surrender of the Premises unless such intent is specifically acknowledged in writing by Landlord or
its management company. The delivery of keys to the Premises to Landlord or any agent or employee
of Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease,
whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery
Tenant shall be entitled to the return of such keys at any reasonable time upon request until this
Lease shall have been properly terminated. The voluntary or other surrender of this Lease by
Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not work a
merger, and at the option of Landlord shall operate as an assignment to Landlord of all subleases
or subtenancies affecting the Premises or terminate any or all such sublessees or subtenancies.

          15.2 Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or
upon any earlier termination of this Lease, Tenant shall, subject to the provisions of this
Article 15, quit and surrender possession of the Premises to Landlord in as good order and
condition as when Tenant took possession and as thereafter improved by Landlord and/or Tenant,
reasonable wear and tear, damage due to casualty or condemnation, or repairs which are specifically
made the responsibility of Landlord hereunder excepted. Upon such expiration or termination,
Tenant shall, without expense to Landlord, remove or cause to be removed from the Premises all
debris and rubbish, and such items of furniture (excepting the Furniture), equipment, business and
trade fixtures, free-standing cabinet work, movable partitions and other articles of personal
property owned by Tenant or installed or placed by Tenant at its expense in the Premises (subject
to Section 8.2 and Section 8.5), and Tenant shall repair at its own expense all
damage to the Premises and Building to the extent resulting from such removal.

ARTICLE 16

HOLDING OVER

          16.1 Interim Premises. If Tenant holds over in the Interim Premises after the
expiration of Transition Period, with or without the express or implied consent of Landlord, such
tenancy shall be such tenancy shall be from month-to-month only, and shall not, except as set forth
below, constitute a renewal hereof or an extension for any further term, and in such case Base Rent
shall be payable at a monthly rate equal to the product of (i) the rentable square footage
contained in that portion of the Interim Premises which has not been timely vacated by
Tenant, and (ii) Thirty Three Dollars and Seventy Five Cents ($33.75) divided by twelve (12),
prorated for the actual number of days in which Tenant holds over in such portion of the Interim
Premises. Such month-to-month tenancy shall be subject to every other applicable TCCs contained
herein. Nothing contained in this Article 16 shall be construed as consent by Landlord

42

 

to
any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to
surrender possession of the Interim Premises to Landlord as provided in this Lease upon the
expiration or other termination of this Lease. The provisions of this Article 16 shall not
be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided
herein or at law. If Tenant fails to surrender the Interim Premises upon the expiration of the
Transition Period, in addition to any other liabilities to Landlord accruing therefrom, Tenant
shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including
reasonable attorneys’ fees) and liability resulting from any claims made by any succeeding tenant
founded upon such failure to surrender.

          16.2 Intentionally Deleted.

          16.3 Premises. If Tenant holds over after the expiration of the Lease Term or earlier
termination thereof, with or without the express or implied consent of Landlord, such tenancy shall
be from month-to-month only, and shall not, except as set forth below, constitute a renewal hereof
or an extension for any further term, and in such case Rent shall be payable at a monthly rate
equal to the product of (i) the Rent applicable during the last rental period of the Lease Term
under this Lease, and (ii) one hundred fifty percent (150%). Such month-to-month tenancy shall be
subject to every other applicable TCCs contained herein. Nothing contained in this
Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and
Landlord expressly reserves the right to require Tenant to surrender possession of the Premises to
Landlord as provided in this Lease upon the expiration or other termination of this Lease. The
provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any
other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the
Premises upon the expiration or earlier termination of the Term, in addition to any other
liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold
Landlord harmless from all loss, costs (including reasonable attorneys’ fees) and liability
resulting from any claims made by any succeeding tenant founded upon such failure to surrender.

ARTICLE 17

ESTOPPEL CERTIFICATES

          Within ten (10) business days following a request in writing by either party hereto, the other
party shall execute, acknowledge and deliver to the requesting party an estoppel certificate,
which, as submitted by Landlord to Tenant, shall be substantially in the form of
Exhibit E-1 attached hereto, and which, as submitted by Tenant to Landlord, shall be
substantially in the form of Exhibit E-2 attached hereto, or such other substantially
similar form containing such other information as shall be reasonably requested by any party to
whom the estoppel certificate is to be provided, and subject to the mutual agreement of Landlord
and Tenant, indicating therein any exceptions thereto that may exist at that time. Any such
certificate may be relied upon by a third party for whose benefit the estoppel certificate has been
requested.

43

 

ARTICLE 18

SUBORDINATION

          This Lease shall be subject and subordinate to all present and future ground or underlying
leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances
now or hereafter in force against the Building or Project or any part thereof, if any, and to all
renewals, extensions, modifications, consolidations and replacements thereof, and to all advances
made or hereafter to be made upon the security of such mortgages or trust deeds, unless the holders
of such mortgages, trust deeds or other encumbrances (collectively, “lienholders”), or the lessors
under such ground lease or underlying leases require in writing that this Lease be superior
thereto. Tenant covenants and agrees in the event any proceedings are brought for the foreclosure
of any such mortgage or deed in lieu thereof (or if any ground lease is terminated), to attorn,
without any deductions or set-offs whatsoever, to the lienholder or purchaser or any successors
thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor), if so
requested to do so by such purchaser or lienholder or ground lessor, and to recognize such
purchaser or lienholder or ground lessor as the lessor under this Lease. Landlord’s interest
herein may be assigned as security at any time to any lienholder. Tenant’s foregoing agreements
concerning subordination of this Lease shall be subject to, in each case, Landlord’s obtaining from
any such lienholder or lessor, and delivering to Tenant a Subordination, Non-Disturbance and
Attornment Agreement (“SNDA”) in commercially reasonably form and substance (provided, however,
that such form shall in no way affect the Term or Rent under this Lease or otherwise materially,
adversely diminish the rights or increase the obligations of Tenant hereunder) whereby such
executing party shall agree not to disturb the tenancy of the Tenant under, and pursuant to the
terms of, this Lease, so long as Tenant shall not be in default hereunder after any applicable
notice and opportunity to cure, and shall agree to attorn to said lienholder or lessor and to
execute, acknowledge and deliver any reasonable instrument that has for its purpose and effect the
confirmation of such subordination, non-disturbance and attornment or superiority of this Lease to
any such mortgages, trust deeds, ground leases or underlying leases in accordance with the TCCs of
this Article 18. Tenant shall execute and deliver to Landlord, at the time it executes
this Lease, and thereafter, upon ten (10) days advance written request, any SNDA that Landlord may
reasonably require on a commercially reasonable, recordable form as required by the applicable
lienholder or ground lessor, subject to any reasonable revisions requested by Tenant and acceptable
to such lienholder. Tenant waives the provisions of any current or future statute, rule or law
which may give or purport to give Tenant any right or election to terminate or otherwise adversely
affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure
proceeding or sale.

ARTICLE 19

DEFAULTS: REMEDIES

          19.1 Events of Default. The occurrence of any of the following shall constitute a
default of this Lease by Tenant:

               19.1.1 Any failure by Tenant to pay any Rent or any other charge required to be paid under
this Lease, or any part thereof, when due unless such failure is cured within five (5)

44

 

business
days after written notice with respect to Base Rent, Tenant’s Electricity Cost and Tenant’s Share
of the Estimated Excess, or within thirty (30) days after written notice with respect to other
items of Additional Rent or other charges required under this Lease, provided, however, Landlord
shall not be required to give written notice more than three (3) times in any twelve (12) month
period; or

               19.1.2 Any failure by Tenant to observe or perform any other provision, covenant or condition
of this Lease to be observed or performed by Tenant where such failure continues for thirty (30)
days after written notice thereof from Landlord to Tenant; provided that if the nature of such
default is such that the same cannot reasonably be cured within a thirty (30) day period, Tenant
shall not be deemed to be in default if it diligently commences such cure within such period and
thereafter diligently proceeds to rectify and cure such default; or

               19.1.3 (a) The making by Tenant of any general arrangement or general assignment for the
benefit of creditors; (b) Tenant becomes a “debtor” as defined in 11 U.S.C. § 101 or any successor
statute thereto (unless, in the case of a petition filed against Tenant, the same is dismissed
within sixty (60) days); (c), the appointment of a trustee or receiver to take possession of
substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in this
Lease, where possession is not restored to Tenant within thirty (30) days; (d) the attachment,
execution or other judicial seizure of substantially all of Tenant’s assets located at the
Premises or of Tenant’s interest in this Lease, where such seizure is not discharged within
sixty (60) days or the date of any sooner sale of any of such assets; or (e) Tenant shall become
subject to any proceeding in bankruptcy or insolvency.

          The notice periods provided herein are in lieu of, and not in addition to, any notice periods
provided by law. As used herein, “default”, “Event of Default” or “breach” by Tenant means a
failure by Tenant referred to above in this Section 19.1 that has not been cured within the
applicable time period (after notice if so required) provided above. An Event of Default, default
or breach shall be deemed to have been cured upon removal or cessation of the event or
circumstances giving rise to such Event of Default, default or breach.

          19.2 Remedies Upon Default. Upon the occurrence of any Event of Default by Tenant,
Landlord shall have, in addition to any other remedies available to Landlord at law or in equity
(all of which remedies shall be distinct, separate and cumulative), the option to pursue any one
(1) or more of the following remedies, each and all of which shall be cumulative and nonexclusive,
without any notice or demand whatsoever.

               19.2.1 Terminate this Lease, in which event Tenant shall immediately surrender the Premises
to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy
which it may have for possession or arrearages in rent, use any lawful means to expel or remove
Tenant and any other person who may be occupying the Premises or any part thereof, without being
liable for prosecution or any claim for damages therefor; and Landlord may recover from Tenant the
following:

	 	(i)	 	The worth at the time of award of the
unpaid rent which had been earned at the time of such termination;
plus

45

 

	 	(ii)	 	The worth at the time of award of the
amount by which the unpaid rent which would have been earned after
termination until the time of award exceeds the amount of such
rental loss that Tenant proves could have been reasonably avoided;
plus
	 
	 	(iii)	 	The worth at the time of award of the
amount by which the unpaid rent for the balance of the Lease Term
after the time of award exceeds the amount of such rental loss that
Tenant proves could have been reasonably avoided; plus
	 
	 	(iv)	 	At Landlord’s election, such other
amounts in addition to or in lieu of the foregoing as may be
permitted from time to time by applicable law.

          The term “rent” as used in this Section 19.2 shall be deemed to be and to mean all
sums of every nature required to be paid by Tenant pursuant to the TCCs of this Lease, whether to
Landlord or to others. As used in Subsections 19.2.1(i) and (ii), above, the “worth at the
time of award” shall be computed by allowing interest at the rate set forth in Article 25
of this Lease through the date of any judgment against Tenant, but in no case greater than the
maximum amount of such interest permitted by law. As used in Subsection 19.2.l (iii)
above, the “worth at the time of award” shall be computed by discounting future liabilities after
the date of any judgment against Tenant at the discount rate of the Federal Reserve Bank of New
York.

               19.2.2 Maintain Tenant’s right to possession in which case this Lease shall continue in
effect whether or not Tenant shall have vacated or abandoned the Premises. In such event,
Landlord shall be entitled to enforce all of Landlord’s rights and remedies under this Lease,
including the right to recover the rent as it becomes due hereunder. No action by Landlord shall
be deemed a termination of this Lease except written notice by Landlord delivered to Tenant
expressly declaring a termination of this Lease. If Landlord maintains Tenant’s right to
possession, Landlord may thereafter elect to terminate this Lease.

               19.2.3 Terminate this Lease and, in addition to any recoveries Landlord may seek under
Section 19.2.1, bring an action to re-enter and regain possession of the Premises in the
manner provided by the laws of the Commonwealth of Massachusetts then in effect.

               19.2.4 Pursue any other remedy now or hereafter available to Landlord under the laws or
judicial decisions of the Commonwealth of Massachusetts.

               19.2.5 Landlord shall at all times have the rights and remedies (which shall be cumulative
with each other and cumulative and in addition to those rights and remedies available under
Sections 19.2.1 through 19.2.4, above, or any law or other provision of this Lease),
without prior demand or notice except as required by applicable law, to seek any declaratory,
injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a
violation or breach of any provision hereof; provided, however, that Landlord shall use
commercially reasonable efforts to mitigate damages.

          19.3 Subleases of Tenant. If Landlord elects to terminate this Lease on account of
any default by Tenant, as set forth in this Article 19, Landlord shall have the right to
terminate

46

 

any and all subleases, licenses, concessions or other consensual arrangements for
possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole discretion,
succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. If Landlord
has terminated this Lease and elected to succeed to Tenant’s interest in any such subleases,
licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such
election, have no further right to or interest in the rent or other consideration receivable
thereunder.

          19.4 No Relief From Forfeiture After Default. Tenant waives all rights of redemption
or relief from forfeiture under any present or future laws or statutes, in the event Tenant is
evicted or Landlord otherwise lawfully takes possession of the Premises by reason of any default by
Tenant under this Lease.

          19.5 Efforts to Relet. No re-entry or repossession, repairs, maintenance, changes,
alterations and additions, reletting, appointment of a receiver to protect Landlord’s interests
hereunder, or any other action or omission by Landlord shall be construed as an election by
Landlord to terminate this Lease or Tenant’s right to possession, or to accept a surrender of the
Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant’s
obligations hereunder, unless express written notice of such intention is sent by Landlord to
Tenant. Tenant hereby irrevocably waives any right otherwise available under any law to redeem or
reinstate this Lease.

          19.6 Landlord Default. Notwithstanding anything to the contrary set forth in this
Lease, Landlord shall be in default in the performance of any obligation required to be performed
by Landlord pursuant to this Lease if Landlord fails to perform such obligation within thirty (30)
days after the receipt of notice from Tenant specifying in detail Landlord’s failure to perform, or
in the case of Emergency (as defined in Section 7.1 above), sufficiently promptly to
prevent avoidable material damage to persons and property, subject in all cases to force majeure;
provided, however, if the nature of Landlord’s obligation is such that more than thirty (30) days
are required for its performance, then Landlord shall not be in default under this Lease if it
shall promptly commence such performance within such thirty (30) day period and thereafter
diligently pursues the same to completion, subject to force majeure. Upon any such default by
Landlord under this Lease, Tenant may, except as otherwise specifically provided in this Lease to
the contrary, take such action as may be reasonably required to cure said default, and/or exercise
any of its rights provided at law or in equity, and Landlord shall reimburse Tenant for its
reasonable out-of-pocket costs to third parties in effecting such cure within thirty (30) days
after receipt of Tenant’s invoice therefore accompanied by copies of all invoices and statements
detailing such costs and such other information as may reasonably be requested by Landlord. Tenant
shall have no right to offset or withhold the payment or Rent as a result of Landlord’s default,
and except as expressly provided in Sections 6.3, 11.1 and 13.1, Tenant shall have
no right to an abatement of rent or to terminate this Lease as the result of Landlord’s default.

ARTICLE 20

COVENANT OF QUIET ENJOYMENT

          Landlord covenants that subject to Tenant’s performance of its obligations under this Lease
Tenant shall, during the Lease Term, peaceably and quietly have, hold and enjoy the

47

 

Premises
subject to the terms, covenants, conditions, provisions and agreements hereof without interference
by any persons lawfully claiming by or through Landlord. The foregoing covenant is in lieu of any
other covenant express or implied.

the Termination Conditions Precedent (as hereinafter defined), Tenant shall have the one(1) time
irrevocable option to terminate this Lease effective as of July 31, 2016 (the “Termination Date”),

expiration date specified for the Lease Term. Any such termination of this Lease shall be subject
to all of the terms and conditions of this Lease, including, without limitation, Article 15
of this Lease. In addition, if Tenant fails to deliver a timely Termination Notice (time being of
the essence thereof), or to satisfy the foregoing Termination Conditions Precedent, including,
without limitation, the delivery of the Termination Payment, then any Termination Notice delivered
by Tenant shall be null and void and of no force and effect, Tenant shall have no right to
terminate this Lease pursuant to this Article 21, and this Lease shall remain in full force
and effect in accordance with the terms hereof.

          21.2 Definitions-Termination Conditions Precedent, Termination Notice, Termination

no Event of Default shall have occurred under this Lease, (iii) the Termination Notice is
accompanied by payment of fifty percent (50%) of the Termination Payment (as hereinafter defined),
which payment shall be fully earned by Landlord when due and shall be nonrefundable under any

determined by Landlord as the interest that would be earned on fifty percent (50%) of the
Termination Payment for a period of three hundred and thirty five (335) days at an interest rate
determined by reference to the interest rate for a US Treasury Note with a maturity matching as
closely as possible the three hundred and thirty five (335) day period as announced on the date of
the Termination Notice in the Wall Street Journal or, if the Wall Street Journal is
not in existence or no longer publishes such rates, a similar financial publication) is paid to
Landlord on or before the date that is thirty (30) days prior to the Termination Date, which
payment shall be fully earned by Landlord when due and
shall be nonrefundable under any circumstance when paid. For purposes of this Article
21, a “Termination Notice” shall mean a written notice from Tenant duly delivered to Landlord
on or prior to July 31, 2015, which expressly states the intention of Tenant to terminate this
Lease in accordance with and subject to the terms and conditions of this Article 21. The

22, Landlord hereby consents to (i) Tenant’s continued operation of the satellite dish located
on the roof of Building 4, in its current location, size and configuration (the “Building 4 Dish”);
and (ii) Tenant’s continued operation of the satellite dish located on the roof of the Building, in
its current location, size and configuration (the “Building 2 Dish” and collectively with the
Building 4 Dish, the “Satellite Dishes”). Tenant agrees and hereby covenants to Landlord as
follows:

                    22.1.1 Installation, service, repair, maintenance and removal of the Satellite Dishes shall
be performed by a reputable contractor that has been approved by Landlord in writing.
Installation, service, repair and maintenance of the Satellite Dishes shall be performed during
normal office hours (8:00 a.m. to 5:00 p.m., Monday to Friday). Tenant shall have access to the
roof of the Building and to the roof of Building 4 for the purposes of such maintenance; provided,
however, that Tenant shall not have access to the roof of any building in the Project unless
accompanied by Landlord’s agent;

                    22.1.2 The installation, operation and maintenance of the Satellite Dishes shall not
interfere with the peaceful enjoyment by any other tenant of its respective premises and/or the
operation of any other antennae or satellite dishes which may be permitted by Landlord;

                    22.1.3 Tenant shall be solely liable for the installation, maintenance, repair and removal of
the Satellite Dishes, and shall remove the Satellite Dishes and repair any damage caused by such
removal prior to the expiration or earlier termination of the Lease. The operation, maintenance
and removal of the Satellite Dishes shall be performed (i) in a good and workmanlike manner, so
that they would not create a hazard to life or property; (ii) in compliance with all applicable
federal, state and local laws, regulations and ordinances, (iii) with due care and regard for
safety and in a manner that will not cause injury or death to persons or damage to property; (iv)
so that no lien or other encumbrance shall be placed on any portion of the Project, and (v) in a
way that will not limit or void any warranty on the roof nor cause nor permit leaking of the roof,
nor impair the structural integrity of any building in the Project;

                    22.1.4 Tenant shall insure that its use and operation of the Satellite Dishes does not create
a nuisance;

                    22.1.5 There shall be no penetrations of the roof of any building in the Project unless
specifically approved by Landlord in writing. Whether or not Landlord approves such penetrations,
in the event the roof leaks, or any other physical damage to the roof occurs as a result of the
installation and/or maintenance of the Satellite Dishes, Landlord shall provide written notice of
such leaks and upon receipt of such notice Tenant shall meet with Landlord or its agent within
twenty-four (24) hours to determine the extent of such damage, and any required

49

 

repairs shall be
performed by a licensed roofing contractor approved by Landlord at the sole cost and expense of
Tenant. If Tenant fails to meet with Landlord as set forth above, declines to complete such
repairs and/or to have such repairs completed within seven days (or such shorter time as may be
prudent under the circumstances), Landlord may, but shall not be obligated to, have the roof
repaired, and Tenant shall reimburse Landlord for the cost thereof as additional rent within ten
(10) days after receipt of an invoice from Landlord; notwithstanding the foregoing, so long as
Landlord is able to undertake said repairs and Tenant reimburses Landlord for the cost thereof as
set forth above, Tenant shall not be deemed to be in default under this Lease for failing to have
undertaken such repairs; and

                    22.1.6 Tenant’s subcontractors for installation, maintenance, service and repair of the
Satellite Dishes shall carry and maintain in force the following insurance with companies
reasonable satisfactory to Landlord, and Tenant shall provide Landlord with insurance certificates
specifying such coverage within thirty (30) days after the Lease Commencement Date (or prior to the
performance of any work by such contractors, if earlier), and annually thereafter:

coverage for all employees engaged in performing services in connection with
the Satellite Dishes, in accordance with all laws which may be applicable to

limit; and
	 
	 	(iii)	 	Automobile Liability insurance coverage covering owned,
non-owned, and rented automotive equipment providing at least Five Hundred
Thousand Dollars ($500,000) for coverage of injury, death or tangible property

partners, members, employees, contractors, agents and representatives from and against all claims,
actions, damages, liability, or other expense, including, without limitation, reasonable attorneys’
fees, which arise or are alleged to arise as a result of (i) the negligence, misfeasance or willful
misconduct of Tenant, its employees, officers, agents, representatives, invitees or contractors
resulting in any accident or injury to any person or damage to property (including without
limitation, damages to the roof of the Building or the structural integrity thereof, and leaking
and damages related to or caused by leaking related to the installation, operation or

ARTICLE 23

SIGNS

          23.1 Monument Signage. Subject to the provisions and conditions of this Article
23, Landlord hereby consents to Tenant’s continued maintenance of the monument sign (the
“Existing Monument”) at the entrance of the Project adjacent to the Building 2 North Parking Field
(hereinafter defined). Provided that Landlord is permitted by the City of Marlborough and any
other governmental authority having jurisdiction, to place signage at the entrance to the Project
(in addition to the Existing Monument), then Tenant may retain the Existing Monument at the
entrance to the Project, provided that Landlord, at Landlord’s election, may relocate the Existing
Monument to another position at the entrance to the Project designated by Landlord. If the City of
Marlborough does not permit signage at the entrance to the Project in addition to the Existing
Monument or if the size or configuration of Landlord’s sign would be affected by the existence of
the Existing Monument, then Landlord shall have the right to modify the Existing Monument, at
Landlord’s sole cost and expense, to include other tenants on the Existing Monument, provided
Tenant’s name on the Existing Monument will be displayed in a prominent manner (as used herein,
“prominent” shall mean in a manner which is consistent with the standards applicable to major
tenants in Comparable Buildings, being first in any list of tenants, and having letters at least as
big as provided for all other major tenants in the Property, subject to the requirements of the
covenants, conditions and restrictions of record and the requirements of the City of Marlborough,
Massachusetts).

          23.2 Building Signage. Subject to the provisions and conditions of this Article
23, Tenant shall have the exclusive right at Tenant’s sole cost and expense, with Landlord’s
prior written consent as to content, size, form and location to place a single sign on the exterior
of the Building. Under no circumstances shall Tenant place a sign on any roof of the Building.
Subject to the provisions and conditions of this Article 23, Landlord hereby consents to
Tenant’s continued maintenance of Tenant’s interior lobby on level 2 of Building 2 and common area
signage at the Project existing as of the Lease Commencement Date.

          23.3 General Signage Provisions. Tenant shall, at its sole cost and expense, prepare
all plans and specifications relating to such signs, obtain all permits and approvals from
governmental authorities required in connection with such signs, and bear all costs and expenses of
constructing, maintaining, repairing, and replacing such signs and the Existing Monument. Landlord
shall have no obligations or liabilities with respect to the design of such signs, the obtaining of
any required permits or approvals with respect thereto, or the construction, installation,
maintenance, repair or replacement thereof, all of which shall be at the sole risk, and sole cost
and expense of Tenant. All of Tenant’s signs and the Existing Monument (and Landlord’s monument at
the entrance to the Project), shall comply with the requirements of the covenants, conditions and
restrictions of record and the requirements of the City of Marlborough, Massachusetts, and Tenant
shall maintain all of Tenant’s signs and the Existing Monument in good condition, in accordance
with Comparable Buildings. All sign(s) and the Existing Monument (excluding Landlord’s monument
signs) shall be removed by Tenant and the
Premises, Building and/or Project (as the case may be) restored, at the sole cost and expense
of Tenant, upon the expiration or sooner termination of the Lease.

51

 

ARTICLE 24

COMPLIANCE WITH LAW

          Tenant shall not do anything or suffer anything to be done in or about the Premises or the
Project which will in any way conflict with any law, statute, ordinance, decrees, codes (including
without limitation building, zoning and accessibility codes), common law, judgments, orders,
rulings, awards or other governmental or quasi-governmental rule, regulation or requirement now in
force or which may hereafter be enacted or promulgated including any “Environmental Laws” as that
term is defined in Section 29.31 of this Lease (“Applicable Laws”). Tenant shall promptly
provide to Landlord a copy of any written notice received by Tenant of violation of any federal,
state, county or municipal laws, regulations, ordinances, orders or directives relating to the use
or condition of the Premises. At its sole cost and expense, Tenant shall promptly comply with all
such governmental measures to the extent that such governmental measures relate to Tenant’s
particular use of the Premises or any Alterations located in the Premises. Should any standard or
regulation now or hereafter be imposed on Landlord or Tenant by a commonwealth, state, federal or
local governmental body charged with the establishment, regulation and enforcement of occupational,
health or safety standards for employers, employees, landlords or tenants, then Tenant agrees, at
its sole cost and expense, to comply promptly with such standards or regulations to the extent such
standards or regulations relate to Tenant’s particular use of the Premises or any Alterations
located in the Premises; provided that Landlord shall comply with any standards or regulations
which relate to the Base Building or the Building Systems, unless such compliance obligations are
triggered by the Alterations in the Premises, in which event such compliance obligations shall be
at Tenant’s sole cost and expense; provided further, and notwithstanding the foregoing, that Tenant
shall not be required to make any repair to, modification of, or addition to the Base Building or
the Building Systems except and to the extent required because of Tenant’s particular use of the
Premises. The judgment of any court of competent jurisdiction or the admission by either party
hereto in any judicial action, regardless of whether this other party is a party thereto, that such
party has violated any of said governmental measures, shall be conclusive of that fact as between
Landlord and Tenant. Landlord shall comply in all material respects with all Applicable Laws
relating to the Project, Base Building and Building Systems, provided that compliance with such
Applicable Laws is not the responsibility of Tenant under this Lease, and provided further that
Landlord’s failure to comply therewith would prohibit Tenant from obtaining or maintaining a
certificate of occupancy for the Premises, or would unreasonably and materially affect the safety
of Tenant’s Parties or create a significant health hazard for Tenant’s Parties or otherwise
materially interfere with or materially affect Tenant’s Permitted Use and enjoyment of the
Premises. Landlord shall be permitted to include in Operating Expenses any costs or expenses
incurred by Landlord under this Article 24 to the extent consistent with, and amortized to
the extent required by, the TCCs of Section 4.2.4 of this Lease, subject to the limitations
set forth in Section 4.2.4 (J).

ARTICLE 25

LATE CHARGES

          If any installment of Rent or any other sum due from Tenant shall not be received by Landlord
or Landlord’s designee within five (5) business days following written notice that Base

52

 

Rent,
Tenant’s Electricity Cost and/or monthly payments of Tenant’s Share of any Estimated Excess was not
paid when due (provided, however, that Landlord shall not be required to give Tenant written notice
more than three (3) times in any twelve (12) month period), or within thirty (30) business days
following written notice that such amount was not paid when due for any other item of Additional
Rent and other sums which may become due under this Lease, then Tenant shall pay to Landlord a late
charge equal to three percent (3%) of the overdue amount. The late charge shall be deemed
Additional Rent and the right to require it shall be in addition to all of Landlord’s other rights
and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting
Landlord’s remedies in any manner. In addition to the late charge described above, any Rent or
other amounts owing hereunder which are not paid within five (5) business days following the due
date for Base Rent, Tenant’s Electricity Cost and/or monthly payments of Tenant’s Share of any
Estimated Excess, or within thirty (30) business days following written notice that such amount was
not paid when due for any other item of Additional Rent and other sums which may become due under
this Lease shall bear interest from the date when due until paid at an annual interest rate equal
to the Prime Rate (as stated under the column “Money Rates” in The Wall Street Journal)
plus four percent (4%); provided, however, in no event shall such annual interest rate exceed the
highest annual interest rate permitted by Applicable Law.

ARTICLE 26

LANDLORD’S RIGHT TO CURE DEFAULT: PAYMENTS BY TENANT

          26.1 Landlord’s Cure. All covenants and agreements to be kept or performed by Tenant
under this Lease shall be performed by Tenant at Tenant’s sole cost and expense and without any
reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant
shall fail to perform any obligation under this Lease, and such failure shall continue in excess of
the time allowed under Section 19.1.2, above, unless a specific time period is otherwise
stated in this Lease, Landlord may, but shall not be obligated to, make any such payment or perform
any such act on Tenant’s part without waiving its rights based upon any default of Tenant and
without releasing Tenant from any obligations hereunder.

          26.2 Tenant’s Reimbursement. Except as may be specifically provided to the contrary
in this Lease, Tenant shall pay to Landlord, within ten (10) days following delivery by Landlord to
Tenant of receipts therefor: (i) sums equal to expenditures reasonably made and obligations
incurred by Landlord in connection with the remedying by Landlord of Tenant’s defaults pursuant to
the provisions of Section 26.1; and (ii) sums equal to all losses, costs, liabilities,
damages and expenses referred to in Article 10 of this Lease. All of such sums shall be
deemed Additional Rent and the right to require it shall be in addition to all of Landlord’s other
rights and remedies hereunder or at law and shall not be construed as liquidated damages or as
limiting Landlord’s remedies in any manner. Tenant’s obligations under this
Section 26.2 shall survive the expiration or sooner termination of the Lease.

53

 

ARTICLE 27

ENTRY BY LANDLORD

          Landlord reserves the right during normal business hours, upon no less than twenty-four (24)
hours prior notice to Tenant (except in the case of an emergency), and in compliance with Tenant’s
reasonable security measures, to enter the Premises to (i) inspect them; (ii) show the Premises to
prospective purchasers, current or prospective mortgagees, ground or underlying lessors or insurers
or, during the last six (6) months of the Lease Term, tenants, or prospective tenants; (iii) post
notices of nonresponsibility; or (iv) improve or repair the Premises or the Building, or for
structural alterations, repairs or improvements to the Building or the Building’s systems and
equipment. Notwithstanding anything to the contrary contained in this Article 27, Landlord
may enter the Premises at any time to (A) perform services required of Landlord, including
janitorial service; (B) take possession due to a breach of this Lease as provided in Article
19; and (C) during normal business hours, upon forty-eight (48) hours prior notice, perform any
covenants of Tenant which Tenant fails to perform. Landlord may make any such entries without the
abatement of Rent and may take such reasonable steps as required to accomplish the stated purposes.
In connection with any entry into the Premises, Landlord agrees to make reasonable efforts to
minimize interference with Tenant’s operations in the Premises caused by such entry and to minimize
the duration of any such interference. Tenant hereby waives any claims for damages or for any
injuries or inconvenience to or interference with Tenant’s business, lost profits, any loss of
occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby, except with
respect to damage to Tenant’s personal property or the amount of any physical injury, but only to
the extent such damage is caused by the negligent acts or omissions or willful misconduct of
Landlord, its agents, employees and contractors, and in such event, only the extent not covered by
Tenant’s insurance required to be carried hereunder. For each of the above purposes, Landlord
shall at all times have a key or card key with which to unlock all the doors in the Premises,
excluding Tenant’s vaults, safes and special security areas designated in advance by Tenant (the
“Security Areas”). Notwithstanding anything set forth in this Article 27 to the contrary,
Landlord shall have no access or inspection rights as to the Security Areas, except in the event of
an emergency where such entry is reasonably required. In an emergency, Landlord and its agents,
employees and contractors shall have the right to use any means that Landlord may deem proper to
open the doors in and to the Premises, provided Landlord has reasonably attempted, but to no avail,
to obtain Tenant’s immediate cooperation in connection therewith. Any entry into the Premises by
Landlord in the manner hereinbefore described shall not be deemed to be a forcible or unlawful
entry into, or a detainer of, the Premises, or an actual or constructive eviction of Tenant from
any portion of the Premises. No provision of this Lease shall be construed as obligating Landlord
to perform any repairs, alterations or decorations except as otherwise expressly agreed to be
performed by Landlord herein.

ARTICLE 28

TENANT PARKING

          Tenant and the Tenant’s parties (including Tenant’s visitors) shall be entitled to utilize,
without charge, and on a non-exclusive basis, commencing on the Lease Commencement Date,

54

 

the amount
of unreserved and unassigned parking spaces in the Project set forth in Section 9 of the
Summary (“Tenant’s Project Parking”); provided, however, that Landlord shall permit fourteen (14)
of the spaces to which Tenant is entitled under Section 9 of the Summary to be reserved in
the 350 Campus Drive North Parking field as shown in Exhibit H (the “Building 2 North Parking
Field”) as near as possible to the entrance of the Building for the exclusive use of Tenant’s
visitors, and Landlord shall install and maintain signage restricting parking for such exclusive
spaces and Tenant shall reimburse Landlord for the cost of installing, repairing and maintaining
said signs as Additional Rent. Landlord shall have no obligation to police or enforce the
restrictions on the use of said reserved parking spaces. Upon leasing by Landlord of any portion
of the Building to a tenant other than Tenant, as part of Tenant’s Project Parking, Tenant shall
only have the non-exclusive use of Tenant’s Building Share of the spaces in the Building 2 North
Parking Field (“Tenant’s Building 2 North Parking Spaces”), which Tenant’s Building 2 North Parking
Spaces shall include the 14 parking spaces reserved for Tenant’s visitors described in this
Article 28. Tenant shall cooperate with Landlord to ensure that Tenant’s agents, servants,
employees, and contractors (collectively, “Tenant Parties”) comply with the Rules and Regulations
which are prescribed from time to time by Landlord for the orderly operation and use of the parking
areas where the parking spaces are located, including Tenant’s cooperation in seeing that Tenant’s
employees and visitors also comply with such Rules and Regulations and Tenant not being in default
under this Lease beyond any applicable notice and cure period. Landlord specifically reserves the
right to make reasonable changes to the size, configuration, design, layout and all other aspects
of the Project parking areas and improvements at any time upon thirty (30) days’ prior written
notice to Tenant and Tenant acknowledges and agrees that Landlord may, without incurring any
liability to Tenant and without any abatement of Rent under this Lease, from time to time,
temporarily close-off or restrict access to portions of the Project parking areas only for purposes
of permitting or facilitating any such construction, alteration or improvements, not to exceed,
without Tenant’s approval, ten (10) business days in any twelve (12) month period; provided,
however, that Landlord will undertake reasonable efforts to minimize the number of parking spaces
affected by and the duration of any such temporary restrictions on use of the parking areas. In no
event shall Tenant’s Share of parking on the Project be permanently reduced below any minimum
parking ratio required under Applicable Laws or in any manner which would materially, adversely
interfere with Tenant’s use and occupancy of the Premises. Landlord may delegate its
responsibilities hereunder to a parking operator in which case such parking operator shall have all
the rights of control attributed hereby to the Landlord. The parking spaces available to Tenant
pursuant to this Article 28 are provided to Tenant solely for use by the Tenant Parties and
such spaces may not be transferred, assigned, subleased or otherwise alienated by Tenant, except on
a pro-rata basis in connection with an assignment or subletting of the Premises permitted or
approved in accordance with the TCCs of Article 14. Tenant shall not utilize any of the
Project parking areas for the long term (e.g., over two weeks) storage of vehicles owned by Tenant,
its employees, contractors and consultants.

ARTICLE 29

MISCELLANEOUS PROVISIONS

          29.1 Terms; Captions. The words “Landlord” and “Tenant” as used herein shall include

provisions hereof apply either to corporations or partnerships or individuals, men or women,

55

 

as the
case may require, shall in all cases be assumed as though in each case fully expressed. The
captions of Articles and Sections are for convenience only and shall not be deemed to limit,
construe, affect or alter the meaning of such Articles and Sections.

          29.2 Binding Effect. Subject to all other provisions of this Lease, each of the
covenants, conditions and provisions of this Lease shall extend to and shall, as the case may
require, bind or inure to the benefit not only of Landlord and of Tenant, but also of their
respective heirs, personal representatives, successors or assigns, provided this clause shall not
permit any assignment by Tenant contrary to the provisions of Article 14 of this Lease.

          29.3 No Air Rights. No rights to any view or to light or air over any property,
whether belonging to Landlord or any other person, are granted to Tenant by this Lease. If at any
time any windows of the Premises are temporarily darkened or the light or view therefrom is
obstructed by reason of any repairs, improvements, maintenance or cleaning in or about the Project,
the same shall be without liability to Landlord and without any reduction or diminution of Tenant’s
obligations under this Lease.

          29.4 Transfer of Landlord’s Interest. Tenant acknowledges that Landlord has the right
to transfer all or any portion of its interest in the Project or Building and in this Lease, and
Tenant agrees that in the event of any such transfer, Landlord shall automatically be released from
all liability under this Lease not accrued on or prior to the date of the transfer, and Tenant
agrees to look solely to such transferee for the performance of Landlord’s obligations hereunder
for events occurring after the date of transfer and to attorn to such transferee. Tenant further
acknowledges that Landlord may assign its interest in this Lease to a mortgage lender as additional
security. Landlord acknowledges that to the extent any Landlord obligation or liability under this
Lease is accrued prior to the date of such transfer or assignment which is not assumed by the
transferee or assignee, the same shall remain an obligation of Landlord.

          29.5 Notice of Lease. Prior to the Lease Commencement Date, both parties shall
execute and acknowledge an amended and restated notice of lease in the form attached hereto as
Exhibit G (the “Amended and Restated Notice of Lease”), to be recorded on the Lease
Commencement Date at Tenant’s sole cost and expense.

          29.6 Landlord’s Title. Landlord’s title is and always shall be paramount to the title
of Tenant. Nothing herein contained shall empower Tenant to do any act which can, shall or may
encumber the title of Landlord.

          29.7 Relationship of Parties. Nothing contained in this Lease shall be deemed or
construed by the parties hereto or by any third party to create the relationship of principal and
agent, partnership, joint venturer or any association between Landlord and Tenant.

          29.8 Application of Payments. Landlord shall have the right to apply payments
received from Tenant pursuant to this Lease, regardless of Tenant’s designation of such payments,
to satisfy any obligations of Tenant hereunder, in such order and amounts as Landlord, in its sole
discretion, may elect.

          29.9 Time of Essence. Time is of the essence with respect to the performance of every
provision of this Lease in which time of performance is a factor.

56

 

          29.10 Partial Invalidity. If any term, provision or condition contained in this Lease
shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application
of such term, provision or condition to persons or circumstances other than those with respect to
which it is invalid or unenforceable, shall not be affected thereby, and each and every other term,
provision and condition of this Lease shall be valid and enforceable to the fullest extent possible
permitted by law.

          29.11 No Warranty. In executing and delivering this Lease, Tenant has not relied on
any representations (except as specifically set forth in this Lease), including, but not limited
to, any representation as to the amount of any item comprising Additional Rent or the amount of the
Additional Rent in the aggregate or that Landlord is furnishing the same services to other tenants,
at all, on the same level or on the same basis, or any warranty or any statement of Landlord which
is not set forth herein or in one (1) or more of the exhibits attached hereto.

          29.12 Landlord Exculpation. The liability of Landlord or the Landlord Parties to
Tenant for any default by Landlord under this Lease or arising in connection herewith or with
Landlord’s operation, management, leasing, repair, renovation, alteration or any other matter
relating to the Project or the Premises shall be limited solely and exclusively to an amount which
is equal to the interest of Landlord in the Project. Neither Landlord, nor any of the Landlord
Parties shall have any personal liability therefor, and Tenant hereby expressly waives and releases
such personal liability on behalf of itself and all persons claiming by, through or under Tenant.
The limitations of liability contained in this Section 29.12 shall inure to the benefit of
Landlord’s and the Landlord Parties’ present and future partners, beneficiaries, officers,
directors, trustees, shareholders, agents and employees, and their respective partners, heirs,
successors and assigns. Under no circumstances shall any present or future partner of Landlord (if
Landlord is a partnership), or trustee or beneficiary (if Landlord or any partner of Landlord is a
trust), or member (if Landlord is a limited liability company) have any liability for the
performance of Landlord’s obligations under this Lease. Notwithstanding any contrary provision
herein, neither Landlord nor the Landlord Parties shall be liable under any circumstances for
injury or damage to, or interference with, Tenant’s business, including but not limited to, loss of
profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill or loss of
use, in each case, however occurring.

          29.13 Entire Agreement. It is understood and acknowledged that there are no oral
agreements between the parties hereto affecting this Lease and this Lease constitutes the parties’
entire agreement with respect to the leasing of the Premises and supersedes and cancels any and all
previous negotiations, arrangements, brochures, agreements and understandings, if any, between the
parties hereto or displayed by Landlord to Tenant with respect to the subject matter thereof, and
none thereof shall be used to interpret or construe this Lease. None of the TCCs of
this Lease can be modified, deleted or added to except in writing signed by the parties
hereto. For the avoidance of doubt, the License Agreement between the parties dated July 18, 2005
is not affected by this clause.

          29.14 Right to Lease. Landlord reserves the absolute right to effect such other
tenancies in the Project as Landlord in the exercise of its sole business judgment shall determine
to best promote the interests of the Building or Project. Tenant does not rely on the fact, nor

57

 

does Landlord represent, that any specific tenant or type or number of tenants shall, during the
Lease Term, occupy any space in the Building or Project.

          29.15 Force Majeure. Any prevention, delay or stoppage due to strikes, lockouts,
labor disputes, acts of God (including inclement weather), inability to obtain utilities (subject
to the provisions of Section 6.3), labor, or materials or reasonable substitutes therefor,
governmental actions, civil commotions, fire or other casualty, and other causes beyond the
reasonable control of the party obligated to perform, except with respect to the obligations
imposed with regard to Rent and other charges to be paid by Tenant pursuant to this Lease
(collectively, a “Force Majeure”), notwithstanding anything to the contrary contained in this
Lease, shall excuse the performance of such party for a period equal to any such prevention, delay
or stoppage and, therefore, if this Lease specifies a time period for performance of an obligation
of either party, that time period shall be extended by the period of any delay in such party’s
performance caused by a Force Majeure; provided, however, such extension shall not exceed sixty
(60) consecutive days.

          29.16 Notices. All notices, demands, statements, designations, approvals or other
communications (collectively, “Notices”) given or required to be given by either party to the other
hereunder or by law shall be in writing, shall be (A) sent by United States certified or registered
mail, postage prepaid, return receipt requested (“Mail”), (B) transmitted by telecopy, if such
telecopy is promptly followed by a Notice sent by Mail, (C) delivered by a nationally recognized
overnight courier, or (D) delivered personally. Any Notice shall be sent, transmitted, or
delivered, as the case may be, to Tenant at the appropriate address set forth in Section 10
of the Summary, or to such other place as Tenant may from time to time designate in a Notice to
Landlord, or to Landlord at the addresses set forth below, or to such other places as Landlord may
from time to time designate in a Notice to Tenant. Any Notice will be deemed given (i) three (3)
days after the date it is posted if sent by Mail, (ii) the date the telecopy is transmitted, (iii)
the date the overnight courier delivery is made, or (iv) the date personal delivery is made or
attempted to be made. If Tenant is required under any separate written agreement between Tenant
and a mortgagee or ground lessor to notify such party of any default by Landlord under this Lease,
then Tenant shall give to such mortgagee or ground or underlying lessor written notice of any
default by Landlord under the TCCs of this Lease by registered or certified mail, and such
mortgagee or ground or underlying lessor shall be given a reasonable opportunity to cure such
default prior to Tenant’s exercising any remedy available to Tenant. As of the date of this Lease,
any Notices to Landlord and Tenant must be sent, transmitted, or delivered, as the case may be, to
the following addresses:

the laws of the Commonwealth of Massachusetts. Except as otherwise provided herein, all

(UNLESS SUCH COUNTERCLAIM SHALL BE MANDATORY) IN ANY SUCH PROCEEDING OR ACTION, BUT SHALL BE
RELEGATED TO AN INDEPENDENT ACTION AT LAW.

          29.21 Submission of Lease. Submission of this instrument for examination or signature
by Tenant does not constitute a reservation of, option for or option to lease, and it is not
effective as a lease or otherwise until execution and delivery by both Landlord and Tenant.

          29.22 Brokers. Landlord and Tenant hereby warrant to each other that they have had no
dealings with any real estate broker or agent in connection with the negotiation of this Lease,
excepting only the real estate brokers or agents specified in Section 12 of the Summary
(the “Brokers”), and that they know of no other real estate broker or agent who is entitled to a
commission in connection with this Lease. Landlord shall be responsible for payment of a
commission to Brokers pursuant to separate agreements between Landlord and Brokers. Each party
agrees to indemnify and defend the other party against and hold the other party harmless from any
and all claims, demands, losses, liabilities, lawsuits, judgments, costs and expenses (including
without limitation reasonable attorneys’ fees) with respect to any leasing commission or equivalent
compensation alleged to be owing on account of any dealings with any real estate broker or agent,
other than the Brokers, occurring by, through, or under the indemnifying party.

          29.23 Independent Covenants. This Lease shall be construed as though the covenants
herein between Landlord and Tenant are independent and not dependent and Tenant hereby expressly
waives the benefit of any statute to the contrary and agrees that if Landlord fails to perform its

shall have the right at any time to change the name of the Project or Building and to install,
affix and maintain any and all signs on the exterior and on the interior of the Project or Building
as Landlord may, in Landlord’s sole discretion, desire. Tenant shall not use the name of the
Project or Building or use pictures or illustrations of the Project or Building in advertising or
other publicity or for any purpose other than as the address of the business to be conducted by
Tenant in the Premises, without the prior written consent of Landlord.

          29.25 Counterparts. This Lease may be executed in counterparts with the same effect
as if both parties hereto had executed the same document. Both counterparts shall be construed
together and shall constitute a single lease.

          29.26 Confidentiality. Tenant hereby acknowledges that the contents of this Lease and
any related documents are confidential information. Tenant shall keep such confidential
information strictly confidential and shall not disclose such confidential information to any
person or entity other than Tenant’s partners, administrators, consultants, financial, legal, and

60

with Landlord, any governmental transportation management organization or any other
transportation-related committees or entities.

          29.28 Building Renovations. Except as expressly set forth in Section 5.5,
Landlord has no obligation and has made no promises to alter, remodel, improve, renovate, repair or
decorate the Premises, Building, or any part thereof and Tenant acknowledges that, except as
expressly set forth in Section 5.4, no representations or warranties respecting the
condition of the Premises or the Building have been made by Landlord to Tenant. However, Tenant
hereby acknowledges that Landlord may during the Lease Term renovate, improve, alter, or modify
(collectively, the “Renovations”) the Project, the Building and/or the Premises including without
limitation the parking structure, Common Areas, systems and equipment, roof, and structural
portions of the same. Tenant hereby agrees that such Renovations and Landlord’s actions in
connection with such Renovations shall in no way constitute a constructive eviction of Tenant nor
entitle Tenant to any abatement of Rent except as expressly provided in Section 6.3.
Landlord shall have no responsibility or for any reason be liable to Tenant for any direct or
indirect injury to or interference with Tenant’s business arising from the Renovations, nor shall
Tenant be entitled to any compensation or damages from Landlord for loss of the use of the whole or
any part of the Premises or of Tenant’s personal property or improvements resulting from the
Renovations or Landlord’s actions in connection with such Renovations, or for any inconvenience or
annoyance occasioned by such Renovations or Landlord’s actions provided the performance of such
Renovations does not materially adversely interfere with Tenant’s use or occupancy of the Premises,
the Project or the Common Areas for the Permitted Use.

          29.29 No Violation. Landlord and Tenant hereby warrant and represent that neither its
execution of nor performance under this Lease shall cause either party to be in violation of any
agreement, instrument, contract, law, rule or regulation by which it is bound, and each party shall
protect, defend, indemnify and hold the other harmless against any claims, demands, losses,
damages, liabilities, costs and expenses, including, without limitation, reasonable attorneys’ fees
and costs, arising from Tenant’s breach of this warranty and representation.

Article 8 (including, without limitation, Landlord’s conditioning its approval upon the
restoration of any portion of the Project disturbed by such installation) shall have the right at
its sole cost and expense to install and maintain its own additional wires, cables, conduits,
auxiliary equipment and other related equipment and facilities from the public street

61

 

into the
Project, the Building and the Premises, and between the Building and the Conference Facilities.

          29.31 Hazardous Substances.

               29.31.1  Definitions. For purposes of this Lease, the following definitions shall
apply: “Hazardous Material(s)” shall mean any substance or material that is described as a toxic
or hazardous substance, waste, material, pollutant, contaminant or infectious waste, or any matter
that in certain specified quantities would be injurious to the public health or welfare, or words
of similar import, in any of the “Environmental Laws,” as that term is defined below in this
Section 29.31.1, or any other words which are intended to define, list or classify
substances by reason of deleterious properties such as ignitability, corrosivity, reactivity,
carcinogenicity, toxicity or reproductive toxicity and includes, without limitation, asbestos,
petroleum (including crude oil or any fraction thereof, natural gas, natural gas liquids,
liquefied natural gas, or synthetic gas usable for fuel, or any mixture thereof), petroleum
products, polychlorinated biphenyls, urea formaldehyde, radon gas, radioactive matter, medical

the Project. Tenant shall not use, store, handle or dispose of any Hazardous Materials, other

applicable Environmental Laws.

               29.31.3  Indemnification. Tenant agrees to indemnify, defend, protect and hold
harmless the Landlord Parties from any and all Claims arising from any Hazardous Materials to the
extent placed in, on, under or about the Premises or the Project at any time beginning on November
26, 2002 by Tenant or Tenant Parties. Landlord agrees to indemnify, defend, protect and hold
harmless the Tenant Parties from any and all Claims arising from any Hazardous Materials released,
stored, used or discharged by Landlord, its employees, agents and contractors, prior to the Lease
Commencement Date or during the Lease Term.

          29.32 Development of the Project.

               29.32.1  Subdivision. Subject to the requirements of Article 28, Landlord
reserves the right to further subdivide all or a portion of the Project and to add to, remove, or
otherwise change the parking areas and Common Areas. In the event of any such change, an
equitable adjustment to the Tenant’s Share, if appropriate, shall be made.

               29.32.2  Other Improvements. If portions of the Project or property adjacent to the
Project (collectively, the “Other Improvements”) are owned by an entity other than Landlord,
Landlord, at its option, may enter into an agreement with the owner or owners of any

62

Project or any other of Landlord’s rights described in this Lease.

               29.32.3  Construction of Project and Other Improvements. Tenant acknowledges that
portions of the Project and/or the Other improvements may be under construction following Tenant’s
occupancy of the Premises, and that such construction may result in levels of noise, dust,
obstruction of access, etc. which are in excess of that present in a fully constructed project.
Tenant hereby waives any and all rent offsets or claims of constructive eviction which may arise
in connection with such construction, provided such construction by Landlord does not interfere
with Tenant’s use or occupancy of the Premises, the Project or the Common Areas for the Permitted
Use.

               29.33 No Consequential Damages. Notwithstanding any provision of this Lease to the
contrary, except as specifically set forth in Article 16 of this lease, under no
circumstances shall either party hereto be liable to the other party for any consequential,
incidental or special damages.

               29.34 Waiver of Landlord’s Lien. Landlord understands that Tenant may lease and/or
purchase with purchase money financing certain of the Alterations, fixtures and equipment which may
be installed in or used in connection with the Premises from time to time during the Lease Term.
Landlord hereby agrees, upon written request of Tenant, to release, waive or subordinate any
landlord’s lien to any such equipment leases, retained title contracts, security interest or other
forms of purchase money financing and within ten (10) business days after Tenant’s written request,
to execute documents, in form and substance reasonably satisfactory to Landlord, that permit the
equipment lessors, title and lien holders, as applicable, the right to enter the Premises during
the Lease Term for the sole purpose of exercising their rights to such Alterations, fixtures and
equipment subject to such leases, retained title contracts, security interest or other forms of
purchase money financing and to foreclose upon and remove such collateral from the Premises,
provided that any damage to the Premises caused by such removal is promptly repaired and restored.

the TIF Agreement that pertain to 3COM Corporation and to provide such information as may
reasonably be requested by Landlord to facilitate Landlord’s compliance with any requirements of

excess of Fifty Thousand Dollars ($50,000) under the Lease (beyond applicable notice and grace
periods) during the prior twenty-four (24) month period, (iii) is not the subject of any bankruptcy
or insolvency proceedings, and is not insolvent, as of the date the offer is made, the date the
offer is accepted, and as of the date of the commencement of the term of the lease with respect to
such space, and (iv) Tenant and/or its Affiliates are in occupancy of one hundred percent (100%) of
the Premises (free of any subleases, other than subleases pursuant to Section 14.7, above),
Tenant shall have a right of first offer to lease with respect to any space available or becoming
available for lease on the second floor in the Building prior to the expiration or earlier
termination of the Lease Term including any renewals thereof (such right to be exercised as more
fully set forth in Subsection 30.2 below).

     Tenant’s right of first offer with respect to such space shall be continuing, but if Tenant
does not accept the space when first offered by Landlord:

	 	a.	 	Landlord shall have no obligation to re-offer the same space to Tenant for a
period of one (1) year but, if any portion of the same space is still available one (1)
year later (and the Lease Term with respect to the Premises has not expired or been
terminated pursuant to the terms of the Lease, as amended and Tenant is in compliance
with Section 30.1), Landlord shall re-offer said portion of the space to Tenant
and Tenant must respond to such re-offer within a period of ten (10) business days;
	 
	 	b.	 	Tenant’s right of first offer with respect to the space shall thereafter also
be subject to the rights then existing or thereafter granted by Landlord to any current
or future tenant of the Project with respect to such tenant’s leased premises.

Nothing in this Article 30 is intended to preclude or limit Landlord’s right to grant
tenants of all or any portion of space in the Building renewal or extension rights in accordance
with Section 30.1 which shall have priority over the rights of Tenant under this Lease.

64

 

          30.2 Procedure. Landlord shall give Tenant written notice (“Landlord’s Notice”) of
the right of first offer to lease, stating the date on which the applicable space (the “Offered
Space”) is expected to become available and the terms under which Landlord is willing to lease such
Offered Space to Tenant (which terms shall provide that (w) the Base Rent for the Offered Space
shall parallel the Base Rent for the Premises such that the Base Rent at the commencement of the
term for the Offered Space shall be the Base Rent then being charged for the Premises, with the
Base Rent for the Offered Space thereafter increasing at the same times and at the same rate as the
Base Rent for the Premises; (x) the lease term for the Offered Space shall be coterminous with the
Lease Term for the Premises; (y) the base year for the Offered Space shall be the Base Year for the
Premises; and (z) Landlord shall provide a tenant improvement allowance for such Offered Space
equal to $X per rentable square foot of the Offered Space where X is Twenty Dollars ($20)
multiplied by a fraction, the numerator of which is the remaining number of months in the Lease
Term for the Premises as of the commencement of the term of the Offered Space and the denominator
of which is one hundred and twenty two (122)). Tenant shall have a period of ten (10) business
days after the date of Landlord’s Notice to Tenant to respond by accepting or rejecting such offer
and if Tenant does not respond within said ten (10) business day period, Tenant will be deemed to
have rejected such offer and Landlord may offer the Offered Space to any third party upon terms
that Landlord deems appropriate, free of this right of first offer to lease (but, subject to
complying with the provisions of this Article 30, if applicable, if the space thereafter
again becomes available for lease during the Lease Term). Following Tenant’s acceptance of a right
of first offer to lease, the parties agree to negotiate in good faith for a period not to exceed
ten (10) business days to enter into a lease or an amendment to lease in form and substance
reasonably satisfactory to the parties, and if the parties do not enter into a lease within said
time period, Tenant will be deemed to have rejected the right of first offer to lease with respect
to the Offered Space and Landlord may offer such Offered Space to any third party upon terms that
Landlord deems appropriate, free of this right of first offer to lease (but, subject to complying
with the provisions of this Article 30, if applicable, if the space thereafter again
becomes available for lease during the Lease Term). If Landlord has not leased such space within
one (1) year (and Lease Term has not expired or been terminated pursuant to the terms of the Lease,
as amended and Tenant is otherwise in compliance with Section 30.1), Landlord must again
offer such space to Tenant, and Tenant must respond to such re-offer within a period of ten (10)
business days.

          30.3 Termination of Rights. Notwithstanding anything to the contrary contained in
this Agreement, upon execution of any lease between Landlord and Tenant (or their respective
successors and/or assigns) for space on the second floor of the Building, the provisions of this
Article 30 shall be and become null and void with respect to such space so leased
thereunder.

          30.4 Estoppel Certificate. Within ten (10) business days after Landlord’s written
request, Tenant shall execute an estoppel certificate in recordable form confirming the provisions
of this Article 30, the dates of any offers to Tenant, whether or not Tenant accepted or
rejected such offer, and such other matters as may be reasonably required by Landlord to determine
Tenant’s rights, if any, under this Article 30.

          30.5 Limitation on Assignment. The provisions of this Article 30 and Tenant’s
rights and obligations hereunder may not be assigned by Tenant separate from an assignment of all
of

65

 

          Tenant’s right, title and interest in this Lease (which assignment is further subject to the
provisions of Article 14 of the this Lease).

66

 

     IN WITNESS WHEREOF, Landlord and Tenant have caused this Lease to be executed the day and date
first above written.
