 Exhibit A 
  

3.10. Registration of the Shares; Compliance with the Securities Act. 
  
 (a) Registration Procedures and Other Matters. The Company shall: 
  
 (i) subject to receipt of necessary information from the Investors after
prompt request from the Company to the Investors to provide such information, prepare and file with the SEC, no later than December 12, 2005 (the earlier of the date such registration statement is actually filed or is required to be filed is
the “Filing Date”), a registration statement on Form S-3, Form S-2, or Form S-1 (the “Registration Statement”) to enable the resale of the Shares and the Warrant Shares by the Investors from time to time through any
quotation system on which the Common Stock is quoted or listed, if applicable, or in privately-negotiated transactions; 
  
 (ii) use its best efforts, subject to receipt of necessary information from the Investors after prompt request from the Company to the Investors to
provide such information (provided that failure on the part of one Investor shall not relieve the Company from its obligation to use best efforts with respect to complying Investors), to cause the Registration Statement to become effective on or
before the date that is the earliest of (1) in the event of no review by the staff of the SEC (the “Staff”), within 5 days of being informed by the Staff that the Staff has decided not to review the Registration Statement, but in no
event later than 30 days after the Filing Date, (2) in the event of a review by the Staff, within 5 days of being informed by the Staff that the Staff have no further comments on such Registration Statement, but in no event later than 90 days
after the Filing Date (the earliest of (1) and (2) thereof, the “Required Effective Date” and the date the Registration Statement is initially declared effective by the SEC, the “Effective Date”), such efforts to
include, without limiting the generality of the foregoing, preparing and filing with the SEC in such period any financial statements that are required to be filed prior to the effectiveness of such Registration Statement; and, in the event that the
filing referred to in Section 3.10(a)(i) above is on a form other than Form S-3, the Company shall use its best efforts, subject to receipt of necessary information from the Investors after prompt request from the Company to the Investors
to provide such information (provided that failure on the part of one Investor shall not relieve the Company from its obligation to use best efforts with respect to complying Investors), to prepare and file with the SEC, within 10 days after the
Company first becomes eligible to file a registration statement on Form S-3, a registration statement on Form S-3 (the “S-3 Registration Statement”) to enable the resale of the Shares and Warrant Shares by the Investors from time to time
through any quotation system on which the Common Stock is quoted or listed or in privately-negotiated transactions; and to use its best efforts to cause the S-3 Registration Statement to become effective as soon as practicable thereafter, such
efforts to include, without limiting the generality of the foregoing, preparing and filing with the SEC as promptly as practicable any financial statements that are required to be filed prior to the effectiveness of such S-3 Registration Statement
(the term “Registration Statement” shall mean the S-1 or S-2 Registration Statement until the S-3 Registration Statement is declared effective by the SEC, after which time it shall mean the S-3 Registration Statement). 
  
 (iii) use its best efforts to prepare and file with the SEC such amendments
and supplements to the Registration Statement and the Prospectus used in 

 connection therewith as may be necessary to keep the Registration Statement current, effective and free from any material
misstatement or omission to state a material fact for a period not exceeding, with respect to each Investor’s Shares purchased hereunder or the Warrant Shares, the earlier of (x) the date on which such Investor may sell all Shares and
Warrant Shares then held by the Investor without restriction by the volume limitations of Rule 144(e) of the Securities Act, or (y) such time as all Shares purchased by such Investor in this offering and all Warrant Shares have been sold
pursuant to a registration statement; 
  
 (iv) furnish to the
Investors with respect to the Shares and Warrant Shares registered under the Registration Statement such number of copies of the Registration Statement, Prospectuses and Preliminary Prospectuses in conformity with the requirements of the Securities
Act and such other documents as the Investors may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Shares and the Warrant Shares by the Investors; 
  
 (v) file documents required of the Company for blue sky clearance in states
specified in writing by any Investor and use its best efforts to maintain such blue sky qualifications during the period the Company is required to maintain the effectiveness of the Registration Statement pursuant to Section 3.10(a)(iii);
provided, however, that the Company shall not be required to qualify to do business or consent to service of process in any jurisdiction in which it is not now so qualified or has not so consented; 
  
 (vi) bear all expenses in connection with the procedures in paragraph
(i) through (v), (viii) and the last paragraph of this Section 3.10(a) and the registration of the Shares and Warrant Shares pursuant to the Registration Statement; 
  
 (vii) advise the Investors, promptly after it shall receive notice or obtain knowledge of the issuance of any stop order by
the SEC delaying or suspending the effectiveness of the Registration Statement or of the initiation or threat of any proceeding for that purpose; and it will promptly use its best efforts to prevent the issuance of any stop order or to obtain its
withdrawal at the earliest possible moment if such stop order should be issued; and 
  
 (viii) provide a “Plan of Distribution” section of the Registration Statement substantially in the form attached hereto as Exhibit E hereto (subject to the comments of the SEC). 
  
 Notwithstanding anything to the contrary herein, the Registration Statement
shall cover only the Shares, Warrant Shares and any other securities with respect to which the Company has registration obligations as of the date hereof. In no event at any time before the Registration Statement becomes effective with respect to
the Shares and the Warrant Shares shall the Company publicly announce or file any other registration statement, other than registrations on Form S-8, without the prior written Majority Investors’ Consent. 
  
 The Company understands that the Investors disclaim being underwriters, but
any Investor being deemed an underwriter by the SEC shall not relieve the Company of any obligations it has hereunder; provided, however that if the Company receives notification from 

 the SEC that an Investor is deemed an underwriter, then the period by which the Company is obligated to submit an
acceleration request to the SEC shall be extended to the earlier of (x) the 90th day after such SEC notification, or (y) 120 days after the initial filing of the Registration Statement with the SEC. 
  
 Within three business days of the Effective Date, the Company shall advise
its transfer agent that the shares are subject to an effective registration statement and can be reissued free of restrictive legend upon notice of a sale by an Investor and confirmation by such Investor that it has complied with the prospectus
delivery requirements, provided that the Company has not advised the transfer agent orally or in writing that the registration statement has been suspended; provided, however, in the event the Company’s transfer agent requires an opinion of
counsel to the Company for an such reissuance, within three business days of any such request for an opinion by the transfer agent, the Company shall cause its counsel to issue a blanket opinion to the transfer agent stating the foregoing.

  
 (b) Transfer of Shares After Registration; Suspension.

  
 (i) Each Investor, severally and not jointly, agrees that it
will not effect any disposition of the Shares, the Warrant Shares or its right to purchase the Shares or Warrant Shares that would constitute a sale within the meaning of the Securities Act except as contemplated in the Registration Statement
referred to in Section 3.10(a) and as described below or as otherwise permitted by law, and that it will promptly notify the Company of any material changes in the information set forth in the Registration Statement regarding the Investor or
its plan of distribution. 
  
 (ii) Except in the event that
paragraph (iii) below applies, the Company shall (x) if deemed necessary by the Company, prepare and file from time to time with the SEC a post-effective amendment to the Registration Statement or a supplement to the related Prospectus or
a supplement or amendment to any document incorporated therein by reference or file any other required document so that such Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading, and so that, as thereafter delivered to purchasers of the Shares and Warrant Shares being sold thereunder, such Prospectus will not contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; (y) provide the Investors copies of any
documents filed pursuant to Section 3.10(b)(ii)(x); and (z) inform each Investor that the Company has complied with its obligations in Section 3.10(b)(ii)(x) (or that, if the Company has filed a post-effective amendment to the
Registration Statement which has not yet been declared effective, the Company will notify the Investor to that effect, will use its best efforts to secure the effectiveness of such post-effective amendment as promptly as possible and will promptly
notify the Investor pursuant to Section 3.10(b)(ii)(x) hereof when the amendment has become effective). 
  
 (iii) Subject to paragraph (iv) below, in the event (w) of any request by the SEC or any other federal or state governmental authority during
the period of effectiveness of the Registration Statement for amendments or supplements to a Registration Statement or related 

 Prospectus or for additional information; (x) of the issuance by the SEC or any other federal or state governmental
authority of any stop order suspending the effectiveness of a Registration Statement or the initiation of any proceedings for that purpose; (y) of the receipt by the Company of any notification with respect to the suspension of the
qualification or exemption from qualification of any of the Shares or Warrant Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; or (z) of any event or circumstance which, upon the advice of
its counsel, necessitates the making of any changes in the Registration Statement or Prospectus, or any document incorporated or deemed to be incorporated therein by reference, so that, in the case of the Registration Statement, it will not contain
any untrue statement of a material fact or any omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the Prospectus, it will not contain any untrue
statement of a material fact or any omission to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; then the Company shall
deliver a notice in writing to each Investor (the “Suspension Notice”) to the effect of the foregoing and, upon receipt of such Suspension Notice, the Investor will refrain from selling any Shares or Warrant Shares pursuant to the
Registration Statement (a “Suspension”) until the Investor’s receipt of copies of a supplemented or amended Prospectus prepared and filed by the Company, or until it is advised in writing by the Company that the current Prospectus may
be used, and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in any such Prospectus. In the event of any Suspension, the Company will use its best efforts to cause the use of
the Prospectus so suspended to be resumed as soon as reasonably practicable within 20 business days after the delivery of a Suspension Notice to the Investors. In addition to and without limiting any other remedies (including, without limitation, at
law or at equity) available to the Investors, each Investor shall be entitled to specific performance in the event that the Company fails to comply with the provisions of this Section 3.10(b)(iii). 
  
 (iv) Notwithstanding the foregoing paragraphs of this Section 3.10(b),
the Investors shall not be prohibited from selling Shares or Warrant Shares under the Registration Statement as a result of Suspensions on more than two occasions of not more than 30 days each in any twelve month period, unless, in the good faith
judgment of the Company’s Board of Directors, upon the advice of counsel, the sale of Shares or Warrant Shares under the Registration Statement in reliance on this Section 3.10(b)(iv) would be reasonably likely to cause a violation of the
Securities Act or the Exchange Act and result in liability to the Company. 
  
 (v) Provided that a Suspension is not then in effect, any Investor may sell Shares and Warrant Shares under the Registration Statement, provided that it arranges for delivery of a current Prospectus to the transferee
of such Shares and Warrant Shares in compliance with applicable law. Upon receipt of a request therefor, the Company has agreed to provide an adequate number of current Prospectuses to the Investors and to supply copies to any other parties
requiring such Prospectuses. 
  
 (vi) In the event of a sale of
Shares or Warrant Shares by an Investor pursuant to the Registration Statement, the Investor must also deliver to the Company’s transfer agent, with a copy to the Company, a Certificate of Subsequent Sale substantially in the form attached
hereto as Exhibit D, so that the Shares or Warrant Shares may be properly transferred. 

 (c) Indemnification. For the purpose of this Section 3.10(c): 
  
 (x) the term “Selling Stockholder” shall include each Investor
and any affiliate of such Investor; 
  
 (y) the term
“Registration Statement” shall include the Prospectus in the form first filed with the SEC pursuant to Rule 424(b) of the Securities Act or filed as part of the Registration Statement at the time of effectiveness if no
Rule 424(b) filing is required, exhibit, supplement or amendment included in or relating to the Registration Statement referred to in Section 3.10(a); and 
  
 (z) the term “untrue statement” shall include any untrue statement or alleged untrue statement, or any omission
or alleged omission to state in the Registration Statement a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 
  
 (i) The Company agrees to indemnify and hold harmless each Selling
Stockholder from and against any losses, claims, damages or liabilities to which such Selling Stockholder may become subject (under the Securities Act or otherwise) insofar as such losses, claims, damages or liabilities (or actions or proceedings in
respect thereof) arise out of, or are based upon (x) any breach of the representations or warranties of the Company contained in this Section 3.10 or failure to comply with the covenants and agreements of the Company contained in this
Section 3.10, (y) any untrue statement of a material fact contained in the Registration Statement as amended at the time of effectiveness or any omission of a material fact required to be stated therein or necessary to make the statements
therein not misleading, or (z) any failure by the Company to fulfill any undertaking included in the Registration Statement as amended at the time of effectiveness, and the Company will reimburse such Selling Stockholder for any reasonable
legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim, or preparing to defend any such action, proceeding or claim, provided, however, that the Company shall
not be liable in any such case to the extent that such loss, claim, damage or liability arises out of, or is based upon, an untrue statement made in such Registration Statement or any omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Selling Stockholder specifically for use in preparation of the Registration
Statement or the failure of such Selling Stockholder to comply with its covenants and agreements contained in Section 3.10(b) hereof respecting sale of the Shares or Warrant Shares or any statement or omission in any Prospectus that is
corrected in any subsequent Prospectus that was delivered to the Selling Stockholder prior to the pertinent sale or sales by the Selling Stockholder. The Company shall reimburse each Selling Stockholder for the amounts provided for herein on demand
as such expenses are incurred. 

 (ii) Each Investor, severally but not jointly, agrees to indemnify and hold harmless the Company (and
each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, each officer of the Company who signs the Registration Statement and each director of the Company) from and against any losses, claims,
damages or liabilities to which the Company (or any such officer, director or controlling person) may become subject (under the Securities Act or otherwise), insofar as such losses, claims, damages or liabilities (or actions or proceedings in
respect thereof) arise out of, or are based upon, (x) any failure to comply with the covenants and agreements contained in Section 3.10(b) hereof respecting sale of the Shares or Warrant Shares, or (y) any untrue statement of a
material fact contained in the Registration Statement or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading if such untrue statement or omission was made in reliance upon and in
conformity with written information furnished by or on behalf of such Investor specifically for use in preparation of the Registration Statement, and such Investor will reimburse the Company (or such officer, director or controlling person), as the
case may be, for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided that such Investor’s obligation to indemnify the Company shall be limited
to the net amount received by such Investor from the sale of the Shares or Warrant Shares giving rise to such obligation. 
  
 (iii) Promptly after receipt by any indemnified person of a notice of a claim or the beginning of any action in respect of which indemnity is to be
sought against an indemnifying person pursuant to this Section 3.10(c), such indemnified person shall notify the indemnifying person in writing of such claim or of the commencement of such action, but the omission to so notify the indemnifying
person will not relieve it from any liability which it may have to any indemnified person under this Section 3.10(c) (except to the extent that such omission materially and adversely affects the indemnifying person’s ability to defend such
action) or from any liability otherwise than under this Section 3.10(c). Subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified person, the indemnifying person shall be entitled to
participate therein, and, to the extent that it shall elect by written notice delivered to the indemnified person promptly after receiving the aforesaid notice from such indemnified person, shall be entitled to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified person. After notice from the indemnifying person to such indemnified person of its election to assume the defense thereof, such indemnifying person shall not be liable to such indemnified person
for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof, provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate, in the
opinion of counsel to the indemnified person, for the same counsel to represent both the indemnified person and such indemnifying person or any affiliate or associate thereof, the indemnified person shall be entitled to retain its own counsel at the
reasonable expense of such indemnifying person; provided, however, that no indemnifying person shall be responsible for the fees and expenses of more than one separate counsel (together with appropriate local counsel) for all
indemnified parties. In no event shall any indemnifying person be liable in respect of any amounts paid in settlement of any action unless the indemnifying person shall have approved the terms of such settlement; provided that such consent
shall not be unreasonably withheld. No indemnifying person shall, 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 indemnification 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. 
  
 (iv) If the indemnification provided for in this Section 3.10(c) is unavailable to or insufficient to hold harmless an
indemnified person under subsection (i) or (ii) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying person shall contribute to the amount
paid or payable by such indemnified person as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and the
applicable Investor, as well as any other Selling Shareholders under such registration statement on the other in connection with the statements or omissions or other matters which resulted in such losses, claims, damages or liabilities (or actions
in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, in the case of an untrue statement, whether the untrue statement relates to information supplied
by the Company on the one hand or an Investor or other Selling Shareholder on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement. The Company and each
Investor, severally but not jointly, agree that it would not be just and equitable if contribution pursuant to this subsection (iv) were determined by pro rata allocation (even if the Investor and other Selling Shareholders were treated as one
entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to above in this subsection (iv). The amount paid or payable by an indemnified person as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (iv) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified person in connection with investigating or
defending any such action or claim. Notwithstanding the provisions of this subsection (iv), each Investor shall not be required to contribute any amount in excess of the amount by which the net amount received by such Investor from the sale of the
Shares and Warrant Shares to which such loss relates exceeds the amount of any damages which such Investor has otherwise been required to pay by reason of such untrue statement. No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Each Investor’s obligations in this subsection to contribute shall be in proportion to its sale
of Shares and Warrant Shares to which such loss relates and shall not be joint with any other Selling Shareholders. 
  
 (v) The parties to this Agreement hereby acknowledge that they are sophisticated business persons who were represented by counsel during the negotiations
regarding the provisions hereof including, without limitation, the provisions of this Section 3.10(c), and are fully informed regarding said provisions. They further acknowledge that the provisions of this Section 3.10(c) fairly allocate
the risks in light of the ability of the parties to investigate the Company and its business in order to assure that adequate disclosure is made in the Registration Statement as required by the Act and the Exchange Act. The parties are advised that
federal or state public policy as interpreted by the courts in certain jurisdictions may be contrary to certain of the provisions of this Section 3.10(c), and the parties hereto hereby expressly waive and relinquish any right or ability to
assert such public policy as a defense to a claim under this Section 3.10(c) and further agree not to attempt to assert any such defense. 

 (d) Delayed Effectiveness. The Company and each Investor, severally but not jointly, agree that
such Investor will suffer damages if the Company fails to fulfill its obligations pursuant to Section 3.10(a) and 3.10(b) hereof and that it would not be possible to ascertain the extent of such damages with precision. Accordingly, the Company
hereby agrees to pay liquidated damages (“Liquidated Damages”) to each Investor under the following circumstances: (i) if the Registration Statement is not filed on or before December 12, 2005 (such an event, a “Filing
Default”); (ii) if the Registration Statement is not declared effective by the SEC on or prior to Required Effective Date (unless extended pursuant to the penultimate paragraph of Section 3.10(b) (the “Effectiveness
Deadline”) (such an event, an “Effectiveness Default”); or (iii) if the Registration Statement (after its effectiveness date) ceases to be effective and available to such Investor for any continuous period that exceeds 30 days or
for one or more periods that exceed in the aggregate 60 days in any 12-month period (such an event, a “Suspension Default” and together with a Filing Default and an Effectiveness Default, a “Registration Default”). In the event
of a Registration Default, the Company shall as Liquidated Damages pay to such Investor, for each 30-day period of a Registration Default, an amount in cash equal to 1% of the aggregate purchase price paid by the Investor pursuant to this Agreement;
provided that in no event shall the aggregate amount of cash to be paid as Liquidated Damages pursuant to this Section 3.10(d) exceed 9% of the aggregate purchase price paid by such Investor (including, the Liquidated Damages for the
period from April 1, 2005 through and including August 31, 2005 occurring prior to the amendment of this Section 3.10 on September 28, 2005). The parties hereto agree that no Liquidated Damages shall accrue from the period
September 1, 2005 through the Filing Date. The Company shall pay the Liquidated Damages as follows: (i) in connection with a Filing Default, on the business day following the Filing Default, and each 30th day thereafter until the Registration Statement has been filed with the SEC; (ii) in connection with an Effectiveness Default, on the business
day following the Effectiveness Deadline, and each 30th day thereafter until the Registration Statement is declared
effective by the SEC; or (ii) in connection with a Suspension Default, on either (x) the 31st consecutive
day of any Suspension or (y) the 61st day (in the aggregate) of any Suspensions in any 12-month period, and
each 30th day thereafter until the Suspension is terminated in accordance with Section 3.10(b). Notwithstanding
the foregoing, all periods shall be tolled during delays directly caused by the action or inaction of any Investor, and the Company shall have no liability to any Investor in respect of any such delay. The Liquidated Damages payable herein shall
apply on a pro rata basis for any portion of a 30-day period of a Registration Default. 
  
 (e) Termination of Conditions and Obligations. The conditions precedent imposed by Section 5.5 or this Section 3.10 upon the transferability of the Shares and Warrant Shares shall cease and terminate
as to any particular number of the Shares and Warrant Shares when such Shares and Warrant Shares shall have been effectively registered under the Securities Act and sold or otherwise disposed of in accordance with the intended method of disposition
set forth in the Registration Statement covering the Shares and Warrant Shares, at the time such Shares and Warrant Shares are eligible for sale pursuant to Rule 144(k) (and the Investor provides the Company with such reasonable and appropriate
customary representations as may be reasonably requested by the Company) or at such time as an opinion of counsel reasonably satisfactory to the Company shall have been rendered to the effect that such conditions are not necessary in order to comply

Sublease, and to Landlord’s knowledge, Sublessor is not, as of the Execution Date of this Sublease, in default of its obligations under the Prime Lease. 
  
 3. SUB-SUBLEASE. Landlord, for and in consideration of the rents herein reserved and of the covenants and agreements herein contained on the part of the Tenant to be
performed, hereby subleases to the Tenant, and the Tenant accepts from the Landlord, certain space described in Section 1(Q) (the “Premises”) and located in the Building which is situated on and a part of the land (the
“Land”) legally described in Exhibit A attached hereto and made a part hereof. Tenant acknowledges that the Premises subleased to Tenant hereunder consists of a portion of the premises leased by Prime Landlord to Sublessor pursuant
to the terms of the Prime Lease and leased by Sublessor to Landlord pursuant to the terms of the Sublease. 
  
 4. GENERAL PROVISIONS REGARDING SUB-SUBLEASE. This Sub-Sublease and all the rights of parties hereunder are subject and subordinate to the Prime Lease and the Sublease. Each party agrees that it will not, by its act
or omission to act, cause a default under the Prime 
  

 -2- 

 Lease or the Sublease. In furtherance of the foregoing, the parties hereby confirm, each to the other, that it is not
practical in this Sub-Sublease agreement to enumerate all of the rights and obligations of the various parties under the Prime Lease and the Sublease and specifically to allocate those rights and obligations in this Sub-Sublease agreement.
Accordingly, in order to afford to Tenant the benefits and obligations of this Sub-Sublease and of those provisions of the Prime Lease and Sublease which by their nature are intended to benefit the party in possession of the Premises, and in order
to protect Landlord against a default beyond any applicable grace or cure period after notice by Tenant which might cause a default or event of default by Sublessor under the Prime Lease or Landlord under the Sublease: 
  
 A. Landlord shall pay, when and as due, all base rent, additional rent and other charges
payable by Landlord to Sublessor under the Sublease. 
  
 B. Except as otherwise
expressly provided herein, Landlord shall perform its covenants and obligations under the Sublease which are not otherwise to be performed hereunder by Tenant on behalf of Landlord, as expressly provided herein. 
  
 C. Except as otherwise expressly provided herein, Sublessor shall perform faithfully and be
bound by all terms, conditions, provisions and agreements of Sublessor under the Prime Lease and shall refrain from performing any act which is prohibited by the negative covenants of the Prime Lease. Subject to the next following sentence,
Sublessor shall indemnify, defend and hold Tenant and Landlord harmless from and against all loss, cost or damage arising from any breach by Sublessor of: (i) its obligations under this Section C, or (ii) its obligations as tenant under
the Prime Lease. Notwithstanding anything to the contrary herein contained, Landlord shall not be responsible for the acts or omissions of Tenant, or Tenant’s agents, employees or contractors. With respect to any affirmative covenant of
Sublessor under the Prime Lease which requires access to the Premises in order to enable Sublessor to perform such affirmative covenant, Sublessor shall have access to the Premises to the extent necessary to perform such covenant, provided however,
that Sublessor gives Tenant reasonable prior advance notice, at least twenty-four hours prior to any such entry, except that no prior notice shall be required in an emergency threatening life or property. 
  
 D. Tenant shall refrain from performing any act which is prohibited by the negative covenants
of the Landlord under the Sublease, or of the Sublessor under the Prime Lease whether set forth in the Prime Lease or Sublease or in any rules and regulations promulgated by Prime Landlord pursuant to the provisions of the Prime Lease, including,
without limitation, those negative covenants set forth in Exhibit F attached to the Prime Lease. Tenant shall indemnify, defend and hold Landlord and Sublessor harmless from and against all loss, cost or damage arising from any breach by Tenant of
its obligations under this Section D. Notwithstanding anything to the contrary herein contained, Tenant shall not be responsible for the acts or negligent omissions of Landlord or Sublessor, or their agents, employees or contractors. Landlord shall
have the right to enter the Premises to cure any default beyond any applicable grace or cure period after notice by Tenant under this Section, provided however, that Landlord gives Tenant reasonable prior advance notice, given at least twenty-four
hours prior to any such entry, except that no prior notice shall be required in an emergency threatening life or property. 
  

 -3- 

 E. Tenant shall provide estoppel certificates and subordination agreements, when requested by Prime Landlord, Sublessor
or Landlord pursuant to the provisions of the Prime Lease or the Sublease. 
  
 F.
During the term of this Sub-Sublease, Landlord shall not enter into an amendment to or modification of the Sublease which is likely to have a material, adverse effect on Tenant or its use or enjoyment of the Premises, unless in each case Landlord
shall first obtain Tenant’s prior approval thereof, which shall not be unreasonably withheld, conditioned or delayed. 
  
 G. Landlord hereby grants to Tenant the right to receive all of the services and benefits with respect to the Premises which are to be provided by Prime Landlord under
the Prime Lease and are, in turn, to be provided by Sublessor under the Sublease. Landlord shall have no duty to perform any obligations of Prime Landlord or Sublessor. For example, Landlord shall not be required to provide the services or repairs
which the Prime Landlord is required to provide under the Prime Lease. Landlord shall have no responsibility for or be liable to Tenant for any default, failure or delay on the part of Prime Landlord in the performance or observance by Prime
Landlord of any of its obligations under the Prime Lease, nor shall such default by Prime Landlord affect this Sub-Sublease or waive or defer the performance of any of Tenant’s obligations hereunder except to the extent that such default by
Prime Landlord excuses performance by Landlord, under the Sublease. Notwithstanding the foregoing, the parties contemplate that Prime Landlord shall, in fact, perform its obligations under the Prime Lease and in the event of any default or failure
of such performance by Prime Landlord, Landlord agrees that it will, upon notice from Tenant, make demand upon Sublessor to make demand upon Prime Landlord to perform its obligations under the Prime Lease, and Landlord will take appropriate legal
action to enforce the Sublease. 
  
 H. Tenant shall have the right to use
twenty-one of the parking spaces allocated to Sublessor under the Prime Lease in accordance with the terms and provisions of the Prime Lease and Tenant shall comply with each and every provision of the Prime Lease relating to such parking spaces
including the obligation to pay therefor. Current parking charges are $200 per month per space. 
  
 I. Subject to and in accordance with the provisions of the Prime Lease, Tenant shall have the right to be listed in the Building’s directory in the elevator lobby and to install and maintain signage in the
elevator lobby on the 10th floor of the Building provided that all consents of Prime Landlord shall have first been
obtained and provided further that Tenant shall comply with each and every provision of the Prime Lease relating to any such signage. 
  
 J. Notwithstanding the foregoing, Tenant shall have no obligation to (i) perform any obligation of Landlord under the Sublease which arose prior to the Commencement
Date and Landlord failed to perform, (ii) repair any damage to the Premises caused by Landlord or Sublessor, (iii) remove any alterations or additions installed within the Premises by Landlord or Sublessor, (iv) indemnify Landlord,
Sublessor or Prime Landlord with respect to any negligence or willful misconduct of Landlord or Sublessor, or their agents, invitees, employees or contractors or other subtenants of the Building other than Tenant, or (v) discharge any liens on
the Premises or the Building which arise out of any work performed, or claimed to e performed, by or at the direction of Landlord or Sublessor. 
  

 -4- 

 5. TERM. The term of this Sublease (hereinafter “Term”) shall commence on the Commencement Date specified in
Section 1(K). The Term shall expire on the date (“Expiration Date”) specified in Section 1(M), unless sooner terminated as otherwise provided elsewhere in this Sublease. 
  
 6. POSSESSION. Landlord agrees to deliver possession of the Premises on or before the date
specified in Section 1(H) in their condition as of the execution and delivery hereof, reasonable wear and tear excepted; that is to say, AS IS. Notwithstanding the foregoing, prior to the Commencement Date, Landlord will, at no cost or
expense to Tenant, use all reasonable efforts to enclose the existing interconnecting staircase between the Premises and the eleventh floor, and shall deliver the Premises to Tenant free and clear of all tenants and occupants. If Landlord is unable
to deliver the Premises to Tenant free and clear of all tenants and occupants and otherwise in the condition required herein on or before September 9, 2005, through no fault of the Tenant, the Rent Commencement Date will be postponed on a day
for day basis until Landlord actually delivers possession of the Premises to Tenant as required by this Sub-Sublease. 
  
 7. TENANT’S USE. The Premises shall not be used or for any use other than the Tenant’s Use set forth in Section 1(R) and for no other purpose
or purposes. 
  
 8. RENT. Beginning on the Rent Commencement Date, Tenant agrees
to pay the Base Rent set forth in Section 1(N) to the Payee specified in Section 1(O), at the address specified in Section 1(P), or to such other payee or at such other address as may be designated by notice in
writing from Landlord to Tenant, without prior demand therefor and without any deduction whatsoever. Tenant’s covenant to pay Base Rent shall be independent of every other covenant in this Sublease. If Base Rent is not paid within three
(3) days of the due date, Tenant shall pay to Landlord from the due date thereof until received by Landlord, an amount equal to the product of three (3) percentage points over the so-called prime rate then currently from time to time
charged to its most favored corporate customers by Bank of America (or its successor), or at any applicable lesser maximum legally permissible rate for debts of this nature times the delinquent payment. 
  
 9. TENANT’S OBLIGATIONS. 
  
 A. To the extent separately metered by the applicable utility company, Tenant shall pay
directly to such utility all charges for any such utility services for the Premises as and when the same shall become due, and if not so separately metered by the applicable utility company, Tenant shall pay its pro rata share of all charges for
such utility services reasonably estimated by Landlord as apportionable to the Premises. 
  
 B. Tenant shall be responsible for, and shall pay, all maintenance, repairs and replacements as to the Premises and its equipment (including the personal property, trade fixtures or business equipment of Tenant or any
sub-subtenant, or anyone claiming by, through or under any such permitted sub-subtenants), to the extent Sublessor is obligated to perform the same under the 
  

 -5- 

 Prime Lease. Tenant shall also be responsible for any costs of maintenance, repairs and replacements which are required
as a result of any particular use or manner of use of the Premises by Tenant or any sub-subtenant. 
  
 C. Tenant shall have twenty-four hour three hundred sixty-five day access to the Premises subject to the provisions of the Prime Lease. Tenant agrees, notwithstanding any provision of this Sublease to the contrary, to
pay to Sublessor any amounts on account of taxes, operating expenses, common area maintenance charges or other expenses billed to Sublessor by Prime Landlord in connection with the Premises, recognizing that (i) the Premises comprise 45% of the
premises demised by the Prime Lease and that (ii) in determining operating expenses pursuant to Article 4 of the Prime Lease, Tenant shall only be required to pay its proportionate share of the amount by which such operating expenses exceed
operating expenses incurred during calendar year 2006, and that (iii) in determining real estate taxes pursuant to Article 4 of the Prime Lease, Tenant shall only be required to pay its proportionate share of the amount by which such taxes
exceed such taxes during fiscal year 2006 (i.e., July 1, 2005 through June 30, 2006). 
  
 10. QUIET ENJOYMENT. Landlord represents that it has full power and authority to enter into this Sub-Sublease, subject to obtaining consent of the Sublessor and the Prime Landlord. So long as Tenant is not in default
beyond any applicable grace or cure period after notice in the performance of its covenants and agreements in this Sub-Sublease, this Sub-Sublease is in full force and effect, Tenant’s quiet and peaceable enjoyment of the Premises shall not be
disturbed or interfered with by Landlord, or by any person claiming by, through or under Landlord. Landlord agrees not to enter into any agreement voluntarily to terminate the sublease prior to the expiration of the term thereof; except as otherwise
set forth in Article 15, hereinbelow. Sublessor agrees not to enter into any agreement voluntarily to terminate the Prime Lease prior to the expiration of the term thereof except as otherwise set forth in Article 15 hereinbelow. 
  
 11. TENANT’S INSURANCE. 
  
 A. Tenant shall procure and maintain, at its own cost and expense, such liability insurance
as is required to be carried by Landlord under the Sublease or by Sublessor under the Prime Lease, naming such Tenant, Landlord, Sublessor, as well as Prime Landlord, in the manner required therein, and such property insurance as is required to be
carried by Sublessor under the Prime Lease to the extent such property insurance pertains to the property of Tenant or the personal property of Tenant. If the Prime Lease requires Sublessor to insure leasehold improvements or alterations, then
Tenant shall insure such leasehold improvements which are located in the Premises, including any leasehold improvements or alterations made by Tenant, (leasehold improvements made by Tenant or any sub-subtenant being collectively hereinafter
referred to as “Tenant Alterations”). 
  
 B. Tenant shall furnish to
Prime Landlord, to Sublessor and to Landlord a copy of a certificate of Tenant’s insurance required hereunder prior to the Commencement Date. 
  
 C. Each party hereby waives claims against the other for property damage provided such waiver shall not invalidate the waiving party’s property insurance; each party
shall attempt to obtain from its insurance carrier a waiver of its right of subrogation. Tenant hereby waives claims against Prime Landlord, Sublessor and Landlord for property damage to the Premises or 
  

 -6- 

 its contents if and to the extent that Sublessor waives such claims against Prime Landlord under the Prime Lease and
Landlord waives such claims under the Sublease. Tenant agrees to obtain, for the benefit of Sublessor, Prime Landlord and Landlord, such waivers of subrogation rights from its insurer as are required of Sublessor under the Prime Lease. Sublessor
agrees to use reasonable efforts in good faith to obtain from Prime Landlord a waiver of claims for insurable property damage losses and an agreement from Prime Landlord to obtain a waiver of subrogation rights in Prime Landlord’s property
insurance, if and to the extent that Prime Landlord waives such claims against Sublessor under the Prime Lease or is required under the Prime Lease to obtain such waiver of subrogation rights. 
  
 12. ASSIGNMENT OR SUBLETTING. 
  
 A. Except as may otherwise be set forth herein, Tenant shall not (i) assign, convey or
mortgage this Sublease or any interest under it; (ii) allow any transfer thereof or any lien upon Tenant’s interest by operation of law; (iii) further sublet the Premises or any part thereof; or (iv) permit the occupancy of the
Premises or any part thereof by anyone other than Tenant. 
  
 B. Notwithstanding
the general prohibition set forth in Section 12(A), Tenant shall have the right to assign its interest in this Sublease and to sublease the Premises, or any portion thereof, provided that Tenant obtains Landlord’s prior written consent.
Such consent by Landlord shall not be unreasonably withheld, conditioned, or delayed; provided however, that any such sublease or assignment shall also be subject to the provisions relating to subleasing and assignment as set forth in the Sublease
and the Prime Lease, including, without limitation, the obligation to obtain Sublessor’s and Prime Landlord’s consent thereto. 
  
 C. Notwithstanding anything to the contrary contained herein, Landlord’s consent shall not be required (unless the consent of Prime Landlord is required) for a
proposed assignment of this Sub-Sublease or subletting of the Premises to an entity (1) that controls, is controlled by or is under common control with Tenant, (2) that acquires all or substantially all of Tenant’s assets or stock or
membership interest, or (3) that merges or consolidates with Tenant. 
  
 13.
RULES. Landlord shall not be liable in any way for damage caused by the non-observance by any of the other tenants of such similar covenants in their leases or of such rules and regulations. 
  
 14. REPAIRS AND COMPLIANCE. Tenant shall promptly pay for the repairs set forth in
Section 9(B) hereof and Tenant shall, at Tenant’s own expense, comply with all laws and ordinances, and all orders, rules and regulations of all governmental authorities and of all insurance bodies and their fire prevention engineers at
any time in force, applicable to the Premises. Landlord represents and warrants that it has not received written notice from any governmental authority that the Premises is not in compliance with any applicable law. 
  
 15. FIRE OR CASUALTY OR EMINENT DOMAIN. In the event of a fire or other casualty affecting
the Building or the Premises, or of a taking of all or a part of the Building or Premises under the power of eminent domain, neither Sublessor nor Landlord shall exercise any right which may have the effect of terminating the Sublease without first
obtaining the prior written consent of Tenant which consent will not unreasonably be withheld, conditioned or delayed. In 
  

 -7- 

 the event the Premises (or access thereto or systems serving the same) are subjected to a fire or other casualty or to a
taking by eminent domain that interferes with the use and enjoyment by Tenant of a material portion of the Premises, Tenant shall be entitled to an equitable adjustment of Base Rent and additional rent until tenantable occupancy is restored. At any
time that such interference has not been remedied and tenantable occupancy restored after one hundred eighty (180) days from the date such interference was first experienced, Tenant may, by notice to Landlord, terminate this Sub-Sublease, and
this shall be Tenant’s sole remedy at law or in equity on account of such failure. 
  
 16. ALTERATIONS AND SURRENDER. Without limiting the generality of Section 4 hereof, Tenant agrees to comply with Section 3.2 of the Prime Lease in connection with any proposed Tenant Alterations to the Premises and
Section 6.1.2 of the Prime Lease in connection with the surrender of the Premises upon expiration of the term of this Sublease so far as the same relates to Tenant Alterations. Both of such provisions are incorporated herein by reference, with
the provisions of such Section binding upon both parties as and to the same extent as they are binding upon Sublessor pursuant to the terms of the Prime Lease and Landlord pursuant to the terms of the Sublease. Where Section 3.2 of the Prime
Lease requires the Prime Landlord’s consent to any alterations to the Premises, Tenant shall be obligated to obtain the consent of all of Prime Landlord, Sublessor and Landlord, such consent by Sublessor and Landlord not to be unreasonably
withheld, conditioned or delayed. Sublessor grants Tenant the right to use, without additional charge during the term of this Sub-Sublease, those items of personal property identified on Exhibit E attached hereto and made a part hereof (the
“Furniture”), together with the existing network wiring/equipment and fixtures located in the Premises as of the Rent Commencement Date. The Furniture will, at no additional charge, become the property of Tenant at the end of the
Sub-Sublease Term, provided that there is not then, and shall not have theretofore been, an Event of Default by Tenant under this Sub-Sublease. 
  
 17. ENCUMBERING TITLE. Tenant shall not do any act which shall in any way encumber the title of Prime Landlord in and to the Building or the Land, nor shall the interest
or estate of Prime Landlord or Landlord be in any way subject to any claim by way of lien or encumbrance, whether by operation of law by virtue of any express or implied contract by Tenant, or by reason of any other act or omission of Tenant. Any
claim to, or lien upon, the Premises, the Building or the Land arising from any act or omission of Tenant shall accrue only against the sub-subleasehold estate of Tenant and shall be subject and subordinate to the paramount title and rights of Prime
Landlord in and to the Building and the Land and the interest of Landlord in the premises leased pursuant to the Prime Lease. Without limiting the generality of the foregoing, Tenant shall not permit the Premises, the Building or the Land to become
subject to any mechanics’, laborers’ or materialmen’s lien on account of labor or material furnished to Tenant or claimed to have been furnished to Tenant in connection with work of any character performed or claimed to have been
performed on the Premises by, or at the direction or sufferance of, Tenant, provided, however, that if so permitted under the Prime Lease, Tenant shall have the right to contest in good faith and with reasonable diligence, the validity of any such
lien or claimed lien if Tenant shall give to Prime Landlord, Sublessor and Landlord such security as may be deemed satisfactory to them to assure payment thereof and to prevent any sale, foreclosure, or forfeiture of the Premises, the Building or
the Land by reason of non-payment thereof, provided further, however, that on final determination of the lien or claim of lien, Tenant shall immediately pay any judgment rendered, with all proper costs and charges, and shall have the lien released
and any judgment satisfied. 
  

 -8- 

 18. LANDLORD’S RESERVED RIGHTS. Landlord reserves the right, on reasonable prior notice, given at least twenty-four
hours in advance, to inspect the Premises, or to exhibit the Premises to persons having a legitimate interest at any time during the Sublease term; provided however, that Landlord gives Tenant reasonable prior advance notice, given at least
twenty-four hours in advance, of any such entry, except that no prior notice shall be required in an emergency threatening life or property. 
  
 19. DEFAULTS. Tenant further agrees that any one or more of the following events shall be considered Events of Default as said term is used herein, that is to say, if:

  
 A. Tenant shall be adjudged an involuntary bankrupt, or a decree or order
approving, as properly filed, a petition or answer filed against Tenant asking reorganization of Tenant under the Federal bankruptcy laws as now or hereafter amended, or under the laws of any State, shall be entered, and any such decree or judgment
or order shall not have been vacated or stayed or set aside within sixty (60) days from the date of the entry or granting thereof; or 
  
 B. Tenant shall file, or admit the jurisdiction of the court and the material allegations contained in, any petition in bankruptcy, or any petition pursuant or purporting
to be pursuant to the Federal bankruptcy laws now or hereafter amended, or Tenant shall institute any proceedings for relief of Tenant under any bankruptcy or insolvency laws or any laws relating to the relief of debtors, readjustment of
indebtedness, reorganization, arrangements, composition or extension; or 
  
 C.
Tenant shall make any assignment for the benefit of creditors or shall apply for or consent to the appointment of a receiver for Tenant or any of the property of Tenant; or 
  
 D. Tenant shall admit in writing its inability to pay its debts as they become due; or 
  
 E. A decree or order appointing a receiver of the property of Tenant shall be made and such
decree or order shall not have been vacated, stayed or set aside within sixty (60) days from the date of entry or granting thereof; or 
  
 F. Tenant shall default in any payment of Base Rent required to be made by Tenant hereunder when due as herein provided and such default shall continue for three
(3) days after notice thereof to Tenant; or 
  
 G. Tenant shall default in
any of the other covenants and agreements herein contained to be kept, observed and performed by Tenant, and such default shall continue for twenty (20) days after notice thereof in writing to Tenant, or such longer period as Tenant may
reasonably require, provided that Tenant commences to cure such default within such twenty (20) day period and thereafter diligently prosecutes such cure to completion. Notwithstanding the foregoing, however, if any such default by Tenant
creates an “Event of Default” by Sublessor under the Prime Lease, such default shall be deemed an immediate Event of Default under this Sublease. 
  

 -9- 

 20. REMEDIES. Upon the occurrence of any one or more Events of Default, Landlord may exercise any remedy against Tenant
which Prime Landlord may exercise for an “Event of Default” by Sublessor under the Prime Lease. 
  
 21. SECURITY DEPOSIT. 
  
 (a) Tenant shall deliver to Landlord, on or before the date fourteen (14) days after Tenant executes and delivers this Sub-Sublease to Landlord, an
Irrevocable Standby Letter of Credit (“Letter of Credit”) which shall be (1) in the form attached hereto as Exhibit D, (2) issued by a bank reasonably acceptable to Landlord with minimum assets of Ten Billion Dollars
($10,000,000,000.00), upon which presentment may be made in Boston, Massachusetts, (3) in an amount equal to Ninety-Nine Thousand Seventy Six and 74/100 Dollars ($99,076.74), and (4) for a term of one (1) year, subject to extension in
accordance with the terms of the Letter of Credit. Tenant shall, on or before the date thirty (30) days prior to the expiration of the term of such Letter of Credit, deliver to Landlord a new Letter of Credit satisfying the foregoing conditions
(“Substitute Letter of Credit”) in lieu of the Letter of Credit then being held by Landlord. Such Letter of Credit shall be automatically renewable in accordance with the last grammatical paragraph of Exhibit D; provided that, in such
event, Tenant shall be required to deliver a Substitute Letter of Credit satisfying the conditions hereof, on or before the date thirty (30) days prior to the expiration of the term of such Letter of Credit, if the issuer of such Letter of
Credit gives notice of its election not to renew such Letter of Credit for any additional period pursuant thereto. Tenant agrees that it shall from time to time, as necessary, whether as a result of a draw on the Letter of Credit by Landlord
pursuant to the terms hereof or as a result of the expiration of the Letter of Credit then in effect, renew or replace the original and any subsequent Letter of Credit so that a Letter of Credit, in the amount required hereunder, is in effect until
a date which is at least thirty (30) days after the Termination Date of the Sub-Sublease. If Tenant fails to furnish such renewal or replacement at least thirty (30) days prior to the stated expiration date of the Letter of Credit then
held by Landlord, Landlord may draw upon such Letter of Credit and hold the proceeds thereof (and such proceeds need not be segregated) as a Security Deposit pursuant to the terms of this Article 21. 
  
 (b) In the event that Tenant is in default of its obligations under the
Sub-Sublease, beyond the expiration of applicable notice and grace periods, then the Landlord shall have the right, at any time after such event, without giving any further notice to Tenant, to draw down from said Letter of Credit (Substitute Letter
of Credit or Additional Letter of Credit, as defined below, as the case may be) (a) the amount necessary to cure such default or (b) if such default cannot reasonably be cured by the expenditure of money, to exercise all rights and
remedies Landlord may have on account of such default, the amount which, in Landlord’s opinion, is necessary to satisfy Tenant’s Liability in account thereof. In the event of any such draw by the Landlord, Tenant shall, within five
(5) business days of written demand therefor, deliver to Landlord an additional Letter of Credit satisfying the foregoing conditions (“Additional Letter of Credit”), except that the amount of such Additional Letter of Credit shall be
the amount of such draw. In addition, in the event of a termination based upon the default of Tenant under the Sub-Sublease, or a rejection of the Sub-Sublease pursuant to the provisions of the Federal Bankruptcy Code, Landlord shall have the right
to draw upon the Letter of Credit (from time to time, if necessary) to cover the full amount of damages and other amounts due from Tenant to Landlord 
  

 -10- 

 under the Sub-Sublease. Any amounts so drawn shall, at Landlord’s election, be applied first to any unpaid rent and
other charges which were due prior to the filing of the petition for protection under the Federal Bankruptcy Code. Tenant hereby covenants and agrees not to oppose, contest or otherwise interfere with any attempt by Landlord to draw down from said
Letter of Credit including, without limitation, by commencing an action seeking to enjoin or restrain Landlord from drawing upon said Letter of Credit. Tenant also hereby expressly waives any right or claim it may have to seek such equitable relief.
In addition to whatever other rights and remedies it may have against Tenant if Tenant breaches its obligations under this paragraph, Tenant hereby acknowledges that it shall be liable for any and all damages which Landlord may suffer as a result of
any such breach. 
  
 (c) In the event that Tenant fails timely to
deliver to Landlord a Substitute Letter of Credit, then the Landlord shall have the right, at any time after such event, without giving any further notice to Tenant or to Landlord, to draw down the Letter of Credit (or Substitute Letter of Credit
and/or Additional Letter(s) of Credit) and to hold the proceeds thereof (“Security Proceeds”) in a segregated bank account in the name of the Landlord as security for Tenant’s obligations under the Sub-Sublease in accordance with the
provisions of this Article 21. 
  
 (d) Upon request of Landlord or
any (prospective) purchaser or mortgagee of the Building, Tenant shall, at its expense, cooperate with Landlord in obtaining an amendment to or replacement of any Letter of Credit which Landlord is then holding so that the amended or new Letter of
Credit reflects the name of the new owner of the Building. 
  
 (e)
To the extent that Landlord has not previously drawn upon any Letter of Credit, Substitute Letter of Credit, Additional Letter of Credit or Security Proceeds (collectively “Collateral”) held by the Landlord, and to the extent that Tenant
is not otherwise in default of its obligations under the Sub-Sublease as of the termination date of the Sub-Sublease, Landlord shall return such Collateral to Tenant on the termination of the term of the Sub-Sublease. 
  
 (f) In no event shall the proceeds of any Letter of Credit be deemed to be a
prepayment of rent nor shall it be considered as a measure of liquidated damages. 
  
 22. NOTICES AND CONSENTS. All notices, demands, requests, consents or approvals which may or are required to be given by either party to the other shall be in writing and shall be deemed given when received or refused if sent by United
States registered or certified mail, postage prepaid, return receipt requested or if sent by overnight commercial courier service (a) if to Tenant, addressed to Tenant at the address specified in Section 1(B) or at such other place
as Tenant may from time to time designate by notice in writing to Landlord or (b) if for Landlord, addressed to Landlord at the address specified in Section 1(C) or at such other place as Landlord may from time to time designate by
notice in writing to Tenant. Each party agrees promptly to deliver a copy of each notice, demand, request, consent or approval from such party to Prime Landlord and Sublessor and promptly to deliver to the other party a copy of any notice, demand,
request, consent or approval received from Prime Landlord or Sublessor. Such copies shall be delivered by overnight commercial courier. 
  
 23. ADDITIONAL SERVICES. Landlord agrees that it will, upon notice from Tenant, make demand upon Sublessor to make demand upon Prime Landlord to provide services required
by 
  

 -11- 

 Tenant in addition to those otherwise required to be provided by Prime Landlord under the Prime Lease. Tenant shall pay
Prime Landlord’s charge for such services promptly after having been billed therefor by Prime Landlord, by Sublessor or by Landlord. 
  
 24. PRIME LANDLORD’S CONSENT. 
  
 A. This Sub-Sublease and the obligations of the parties hereunder are expressly conditioned upon Prime Landlord, Sublessor, Landlord and Tenant executing and delivering a
consent to this Sublease which is reasonably acceptable to Sublessor, Landlord and Tenant. Tenant shall promptly deliver to Landlord any information reasonably requested by Prime Landlord (in connection with Prime Landlord’s approval of this
Sublease) with respect to the nature and operation of Tenant’s business and/or financial condition of Tenant. To the extent that Landlord has not already done so, upon execution of this Sub-Sublease by Tenant, Landlord will promptly apply to
the Prime Landlord for the Consent and Landlord will promptly inform Tenant as to receipt of the Consent (if and when it is received) and deliver to Tenant a copy of the same. If the Consent is not received by September 7, 2005 (the
“Sunset Date”), then from the Sunset Date, at the election of Tenant, exercised prior to the receipt of such consent, this Sub-Sublease will cease to have any further effect and the parties hereto will have no further obligations to each
other with respect to this Sub-Sublease and any funds paid hereunder by Tenant shall be promptly refunded by Landlord. 
  
 B. Landlord shall have the exclusive right to initiate, coordinate, and control all discussions with Prime Landlord in obtaining Prime Landlord’s consent to this
Sub-Sublease. 
  
 25. BROKERAGE. Each party warrants to the other that it has had
no dealing with any broker or agent in connection with this Sub-Sublease other than Broker, and covenants to pay, hold harmless and indemnify the other party from and against any and all costs (including reasonable attorneys’ fees), expense or
liability for any compensation, commissions and charges claimed by any other broker or other agent with respect to this Sublease or the negotiation thereof on behalf of such party. Landlord covenants and agrees that it shall pay any and all of the
fees and commissions due to Broker arising from this Sublease transaction. 
  
 26.
FORCE MAJEURE. Neither party (“Performing Party”) shall be deemed in default with respect to any of the terms, covenants and conditions of this Sublease on the part of the Performing Party to be performed, if the Performing Party’s
failure to timely perform same is due in whole or in part to any strike, lockout, labor trouble (whether legal or illegal), civil disorder, failure of power, restrictive governmental laws and regulations, riots, insurrections, war, shortages,
accidents, casualties, acts of God, acts caused directly by the other party or the agents, employees and invitees of the Performing Party or any other cause beyond the reasonable control of the Performing Party. In no event shall financial inability
be deemed to be a cause beyond a party’s reasonable control. This Section shall not be applicable, however, if the Performing Party’s failure timely to perform creates a default by Sublessor under the Prime Lease or a default by Landlord
under the Sublease. 
  
 27. GOVERNING LAW. This Sublease shall be governed by and
construed and enforced in accordance with and subject to the laws of the Commonwealth of Massachusetts, without regard to its conflicts of laws principles. 
  

 -12- 

 28. CONSEQUENTIAL DAMAGES. Notwithstanding anything to the contrary contained herein, in no event shall either party be
liable to the other party for consequential, incidental, or indirect damages, or the lost profits of the other party. 
  
 29. ATTORNEYS’ FEES. If either Landlord or Tenant shall bring any action or legal proceeding for an alleged breach of any provision of this Sub-Sublease, to recover
Base Rent or additional rent, to terminate this Sub-Sublease or otherwise to enforce, protect or establish any term or covenant of this Sub-Sublease, the prevailing party shall be entitled to recover as a part of such action or proceeding, or in a
separate action brought for that purpose, reasonable attorneys’ fees, court costs, and expert fees as may be fixed by the court.
