The Committee shall in any event make such adjustments as may be required by Section 25102(o) of the California Corporation Code and the rules and regulations promulgated thereunder.  The adjustment by the Committee shall be final, binding and conclusive.

(C)Notwithstanding anything to the contrary in Section 3(c)(i)(A), in the event of a Sale Event, the Company shall have the right, but not the obligation, to make or provide for a cash payment to the Holders of Options, without any consent of the Holders, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the value as determined by the Committee of the consideration payable per share of Stock pursuant to the Sale Event (the “Sale Price”) times the number of Shares subject to outstanding Options being cancelled (to the extent then vested and exercisable, 
7

including by reason of acceleration in connection with such Sale Event, at prices not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding vested and exercisable Options.
(ii)Restricted Stock and Restricted Stock Unit Awards.
(A)In the case of and subject to the consummation of a Sale Event, all unvested Restricted Stock and unvested Restricted Stock Unit Awards (other than those becoming vested as a result of the Sale Event) issued hereunder shall be forfeited immediately prior to the effective time of any such Sale Event unless assumed or continued by the successor entity, or awards of the successor entity or parent thereof are substituted therefor, with an equitable or proportionate adjustment as to the number and kind of shares subject to such awards as such parties shall agree (after taking into account any acceleration hereunder and/or pursuant to the terms of any Award Agreement).

SECTION 4.ELIGIBILITY
Grantees under the Plan will be such full or part-time officers and other employees, directors and Consultants of the Company and any Subsidiary who are selected from time to time by the Committee in its sole discretion; provided, however, that Awards shall be granted only to those individuals described in Rule 701(c) of the Securities Act.
SECTION 5.STOCK OPTIONS
Upon the grant of a Stock Option, the Company and the grantee shall enter into an Award Agreement.  The terms and conditions of each such Award Agreement shall be determined by the Committee, and such terms and conditions may differ among individual Awards and grantees.
Stock Options granted under the Plan may be either Incentive Stock Options or Non- Qualified Stock Options.  Incentive Stock Options may be granted only to employees of the Company or any Subsidiary that is a “subsidiary corporation” within the meaning of Section 424(f) of the Code.  To the extent that any Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option.
8

(a)Terms of Stock Options.  The Committee in its discretion may grant Stock Options to those individuals who meet the eligibility requirements of Section 4.  Stock Options shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Committee shall deem desirable.
(i)Exercise Price.  The exercise price per share for the Shares covered by a Stock Option shall be determined by the Committee at the time of grant but shall not be less than 100 percent of the Fair Market Value on the Grant Date.  In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the exercise price per share for the Shares covered by such Incentive Stock Option shall not be less than 110 percent of the Fair Market Value on the Grant Date.
(ii)Option Term.  The term of each Stock Option shall be fixed by the Committee, but no Stock Option shall be exercisable more than ten years from the Grant Date. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the term of such Stock Option shall be no more than five years from the Grant Date.
(iii)Exercisability; Rights of a Stockholder.  Stock Options shall become exercisable and/or vested at such time or times, whether or not in installments, as shall be determined by the Committee at or after the Grant Date.  The Award Agreement may permit a grantee to exercise all or a portion of a Stock Option immediately at grant; provided that the Shares issued upon such exercise shall be subject to restrictions and a vesting schedule identical to the vesting schedule of the related Stock Option, such Shares shall be deemed to be Restricted Stock for purposes of the Plan, and the optionee may be required to enter into an additional or new Award Agreement as a condition to exercise of such Stock Option.  An optionee shall have the rights of a stockholder only as to Shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options.  An optionee shall not be deemed to have acquired any Shares unless and until a Stock Option shall have been exercised pursuant to the terms of the Award Agreement and this Plan and the optionee’s name has been entered on the books of the Company as a stockholder.
(iv)Method of Exercise.  Stock Options may be exercised by an optionee in whole or in part, by the optionee giving written or electronic notice of exercise to the Company, specifying the number of Shares to be purchased.  Payment of the purchase price may be made by one or more of the following methods (or any combination thereof) to the extent provided in the Award Agreement:
(A)In cash, by certified or bank check, by wire transfer of immediately available funds, or other instrument acceptable to the Committee;
(B)If permitted by the Committee, by the optionee delivering to the Company a promissory note, if the Board has expressly authorized the loan of funds to the optionee for the purpose of enabling or assisting the optionee to effect the exercise of his or her Stock Option; provided, that at least so much of the exercise price as represents the par value of the Stock shall be paid in cash if required by state law;
9

(C)If the Initial Public Offering has occurred (or the Stock otherwise becomes publicly-traded), through the delivery (or attestation to the ownership) of Shares that have been purchased by the optionee on the open market or that are beneficially owned by the optionee and are not then subject to restrictions under any Company plan. To the extent required to avoid variable accounting treatment under ASC 718 or other applicable accounting rules, such surrendered Shares if originally purchased from the Company shall have been owned by the optionee for at least six months.  Such surrendered Shares shall be valued at Fair Market Value on the exercise date;
(D)If permitted by the Committee, by the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company for the purchase price; provided that in the event the optionee chooses to pay the purchase price as so provided, the optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Committee shall prescribe as a condition of such payment procedure; or
(E)If permitted by the Committee, and only with respect to Stock Options that are not Incentive Stock Options, by a “net exercise” arrangement pursuant to which the Company will reduce the number of Shares issuable upon exercise by the largest whole number of Shares with a Fair Market Value that, as of the date when the exercise price is to be paid to the Company, does not exceed the aggregate exercise price.
Payment instruments will be received subject to collection.  No certificates for Shares so purchased will be issued to the optionee or, with respect to uncertificated Stock, no transfer to the optionee on the records of the Company will take place, until the Company has completed all steps it has deemed necessary to satisfy legal requirements relating to the issuance and sale of the Shares, which steps may include, without limitation, (i) receipt of a representation from the optionee at the time of exercise of the Option that the optionee is purchasing the Shares for the optionee’s own account and not with a view to any sale or distribution of the Shares or other representations relating to compliance with applicable law governing the issuance of securities, (ii) the legending of the certificate (or notation on any book entry) representing the Shares to evidence the foregoing restrictions, and (iii) obtaining from optionee payment or provision for all withholding taxes due as a result of the exercise of the Option.  The delivery of certificates representing the shares of Stock (or the transfer to the optionee on the records of the Company with respect to uncertificated Stock) to be purchased pursuant to the exercise of a Stock Option will be contingent upon (A) receipt from the optionee (or a purchaser acting in his or her stead in accordance with the provisions of the Stock Option) by the Company of the full purchase price for such Shares and the fulfillment of any other requirements contained in the Award Agreement or applicable provisions of laws and (B) if required by the Company, the optionee shall have entered into any stockholders agreements or other agreements with the Company and/or certain other of the Company’s stockholders relating to the Stock.  In the event an optionee chooses to pay the purchase price by previously-owned Shares through the attestation method, the number of Shares transferred to the optionee upon the exercise of the Stock Option shall be net of the number of Shares attested to.
10

(b)Annual Limit on Incentive Stock Options.  To the extent required for “incentive stock option” treatment under Section 422 of the Code, the aggregate Fair Market Value (determined as of the Grant Date) of the Shares with respect to which Incentive Stock Options granted under the Plan and any other plan of the Company or its parent and any Subsidiary that become exercisable for the first time by an optionee during any calendar year shall not exceed $100,000 or such other limit as may be in effect from time to time under Section 422 of the Code.  To the extent that any Stock Option exceeds this limit, it shall constitute a Non-Qualified Stock Option.
(c)Termination.  Any portion of a Stock Option that is not vested and exercisable on the date of termination of an optionee’s Service Relationship shall immediately expire and be null and void.  Once any portion of the Stock Option becomes vested and exercisable, the optionee’s right to exercise such portion of the Stock Option (or the optionee’s representatives and legatees as applicable) in the event of a termination of the optionee’s Service Relationship shall continue until the earliest of: (i) the date which is: (A) 12 months following the date on which the optionee’s Service Relationship terminates due to death or Disability (or such longer period of time as determined by the Committee and set forth in the applicable Award Agreement), or (B) three months following the date on which the optionee’s Service Relationship terminates if the termination is due to any reason other than death or Disability (or
such longer period of time as determined by the Committee and set forth in the applicable Award Agreement), or (ii) the Expiration Date set forth in the Award Agreement; provided that notwithstanding the foregoing, an Award Agreement may provide that if the optionee’s Service Relationship is terminated for Cause, the Stock Option shall terminate immediately and be null and void upon the date of the optionee’s termination and shall not thereafter be exercisable.
SECTION 6.RESTRICTED STOCK AWARDS
(a)Nature of Restricted Stock Awards.   The Committee may, in its sole discretion, grant (or sell at par value or such other purchase price determined by the Committee) to an eligible individual under Section 4 hereof a Restricted Stock Award under the Plan.  The Committee shall determine the restrictions and conditions applicable to each Restricted Stock Award at the time of grant.  Conditions may be based on continuing employment (or other Service Relationship), achievement of pre-established performance goals and objectives and/or such other criteria as the Committee may determine.

The grantee shall be entitled to receive all dividends and any other distributions declared on the Shares; provided, however, that the Company is under no duty to declare any such dividends or to make any such distribution.  Unless the Committee shall otherwise determine, certificates evidencing the Restricted Stock shall remain in the possession of the 
11

Company until such Restricted Stock is vested as provided in subsection (d) below of this Section, and the grantee shall be required, as a condition of the grant, to deliver to the Company a stock power endorsed in blank and such other instruments of transfer as the Committee may prescribe.
(c)Restrictions.  Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein or in the Award Agreement.

(d)Vesting of Restricted Stock. The Committee at the time of grant shall specify in the Award Agreement the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the substantial risk of forfeiture imposed shall lapse and the Restricted Stock shall become vested, subject to such further rights of the Company as may be specified in the Award Agreement.
SECTION 7.UNRESTRICTED STOCK AWARDS
The Committee may, in its sole discretion, grant (or sell at par value or such other purchase price determined by the Committee) to an eligible person under Section 4 hereof an Unrestricted Stock Award under the Plan.

Restricted Stock Units may not be sold, assigned, transferred, pledged, or otherwise encumbered or disposed of.
(b)Rights as a Stockholder.  A grantee shall have the rights of a stockholder only as to Shares, if any, acquired upon settlement of Restricted Stock Units. A grantee shall not be deemed to have acquired any such Shares unless and until the Restricted Stock Units shall have been settled in Shares pursuant to the terms of the Plan and the Award Agreement, the Company shall have issued and delivered a certificate representing the Shares to the grantee (or transferred 
12

on the records of the Company with respect to uncertificated stock), and the grantee’s name has been entered in the books of the Company as a stockholder.
(c)Termination.  Except as may otherwise be provided by the Committee either in the Award Agreement or in writing after the Award Agreement is issued, a grantee’s right in all Restricted Stock Units that have not vested shall automatically terminate upon the grantee’s cessation of Service Relationship with the Company and any Subsidiary for any reason.
SECTION 9.TRANSFER RESTRICTIONS; RIGHT OF FIRST REFUSAL; COMPANY REPURCHASE RIGHTS
(a)Restrictions on Transfer.
(i)Non-Transferability of Stock Options.  Stock Options and, prior to exercise, the Shares issuable upon exercise of such Stock Option, shall not be transferable by the optionee otherwise than by will, or by the laws of descent and distribution or pursuant to a domestic relations order, and all Stock Options shall be exercisable, during the optionee’s lifetime, only by the optionee, or by the optionee’s legal representative or guardian in the event of the optionee’s incapacity.  Notwithstanding the foregoing, the Committee, in its sole discretion, may provide in the Award Agreement regarding a given Stock Option that the optionee may transfer by gift, without consideration for the transfer, his or her Non-Qualified Stock Options to his or her family members (as defined in Rule 701 of the Securities Act), to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners (to the extent such trusts or partnerships are considered “family members” for purposes of Rule 701 of the Securities Act), provided that the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Award Agreement, including the execution of a stock power upon the issuance of Shares. Stock Options, and the Shares issuable upon exercise of such Stock Options, shall be restricted as to any pledge, hypothecation, or other transfer, including any short position, any “put equivalent position” (as defined in the Exchange Act) or any “call equivalent position” (as defined in the Exchange Act) prior to exercise.
(ii)Shares.  No Shares shall be sold, assigned, transferred, pledged, hypothecated, given away or in any other manner disposed of or encumbered, whether voluntarily or by operation of law, unless (i) the transfer is in compliance with the terms of the applicable Award Agreement, the Company’s bylaws, all applicable securities laws (including, without limitation, the Securities Act), and with the terms and conditions of this Section 9, (ii) the transfer does not cause the Company to become subject to the reporting requirements of the Exchange Act, and (iii) the transferee consents in writing to be bound by the provisions of the Plan and the Award Agreement, including this Section 9.  In connection with any proposed transfer, the Committee may require the transferor to provide at the transferor’s own expense an opinion of counsel to the transferor, satisfactory to the Committee, that such transfer is in compliance with all foreign, federal and state securities laws (including, without limitation, the Securities Act).  Any attempted transfer of Shares not in accordance with the terms and conditions of this Section 9 shall be null and void, and the Company shall not reflect on its records any change in record ownership of any Shares as a result of any such transfer, shall otherwise refuse to recognize any such transfer and shall not in any way give effect to any such 
13

transfer of Shares.  The Company shall be entitled to seek protective orders, injunctive relief and other remedies available at law or in equity including, without limitation, seeking specific performance or the rescission of any transfer not made in strict compliance with the provisions of this Section 9.  Subject to the foregoing general provisions, and unless otherwise provided in the applicable Award Agreement, Shares may be transferred pursuant to the following specific terms and conditions (provided that with respect to any transfer of Restricted Stock, all vesting and forfeiture provisions shall continue to apply with respect to the original recipient):
(A)Transfers to Permitted Transferees.  The Holder may transfer any or all of the Shares to one or more Permitted Transferees; provided, however, that following such transfer, such Shares shall continue to be subject to the terms of this Plan (including this Section 9) and such Permitted Transferee(s) shall, as a condition to any such transfer, deliver a written acknowledgment to that effect to the Company and shall deliver a stock power to the Company with respect to the Shares.  Notwithstanding the foregoing, the Holder may not transfer any of the Shares to a Person whom the Company reasonably determines is a direct competitor or a potential competitor of the Company or any of its Subsidiaries.
(B)Transfers Upon Death.  Upon the death of the Holder, any Shares then held by the Holder at the time of such death and any Shares acquired after the Holder’s death by the Holder’s legal representative shall be subject to the provisions of this Plan, and the Holder’s estate, executors, administrators, personal representatives, heirs, legatees and distributees shall be obligated to convey such Shares to the Permitted Transferees of the Holder in accordance with paragraph (A) above or to the ROFR Holders or the Company in accordance with Section 9(b) below and otherwise on the terms contemplated by the Plan and the Award Agreement.
(b)Right of First Refusal.  In the event that a Holder desires at any time to sell or otherwise transfer all or any part of his or her Shares (other than shares of Restricted Stock which by their terms are not transferrable), the Holder first shall, not later than forty-five (45) Business Days and not earlier than sixty (60) Business Days prior to consummation of such transfer, give written notice to the Company of the Holder’s intention to make such transfer (“Transfer Notice”). The Transfer Notice shall state the number of Shares that the Holder proposes to sell (the “Offered Shares”), the price and the terms at which the proposed sale is to be made and the name and address of the proposed transferee.  The Company shall promptly and in any event within three (3) Business Days of receipt forward the Transfer Notice to each Investor and Founder (each a “ROFR Holder”). Each ROFR Holder shall have the right of first refusal to purchase up to its pro rata portion (based upon the total number of shares of Capital Stock then held by all ROFR Holders on an as-converted to Common Stock basis) of the Offered Shares, at the price and on the terms and conditions specified in the Transfer Notice by delivering a written notice (“ROFR Notice”) to the Company within fifteen (15) Business Days after delivery of the Transfer Notice to such ROFR Holder (“Exercise Period”) specifying the number of Offered Shares to be purchased by such ROFR Holder. If the right to purchase the Offered Shares has been exercised by the ROFR Holders with respect to some but not all of the Offered Shares by the end of the Exercise Period, then the Company shall, within five (5) Business Days after the expiration of the Exercise Period, send written notice (the “Undersubscription Notice”) to those 
14

ROFR Holders who fully exercised their right of first refusal within the Exercise Period (the “Exercising Holders”). Each Exercising Holder shall, subject to the provisions of this Section 9(b), have an additional option to purchase all or any part of the balance of any such remaining unsubscribed Offered Shares on the terms and conditions set forth in the Transfer Notice.  To exercise such option, an Exercising Holder must deliver an Undersubscription Notice to the Company within ten (10) Business Days after the expiration of the Exercise Period (“Overallotment Notice Period”).  In the event there are two (2) or more such Exercising Holders that choose to exercise the last-mentioned option for a total number of remaining Offered Shares in excess of the number available, the remaining shares available for purchase shall be allocated to such Exercising Holders pro rata based on the number of Offered Shares such Exercising Holders have elected to purchase pursuant to the right of first refusal (without giving effect to any shares of Transfer Stock that any such Exercising Holder has elected to purchase pursuant to the Undersubscription Notice).  If the right to purchase the remaining Offered Shares is exercised in full by the Exercising Holders, the Company shall immediately notify all of the Exercising Holders and the selling Holder of that fact. If the ROFR Holders have not elected to purchase all Offered Shares pursuant to the provisions above, the Company shall have a secondary right of first refusal to purchase any such Offered Shares not elected to be purchased by the ROFR Holders at the price and on the terms and conditions specified in the Transfer Notice. The Company shall exercise this right by mailing or delivering written notice to the Holder within the 30-day period following the Overallotment Notice Period. If the ROFR Holders or the Company, as applicable, elect to exercise their purchase rights under this Section 9(b), the closing for such purchase shall, in any event, take place by the later of (i) the date specified in the Transfer Notice as the intended date of the proposed transfer; and (ii) ninety (90) Business Days after delivery of the Transfer Notice.  In the event that the ROFR Holders and the Company do not elect to exercise such purchase right, or in the event that the ROFR Holders or the Company, as applicable, do not pay the full purchase price at or before closing, the Holder shall be required to pay a transaction processing fee of $10,000 to the Company (unless waived by the Committee) and then may, within 60 days thereafter, sell the Offered Shares to the proposed transferee and at the same price and on the same terms as specified in the Transfer Notice.  Any Shares not sold to the proposed transferee shall remain subject to the Plan.  If the Holder is a party to any stockholders agreements or other agreements with the Company and/or certain other of the Company’s stockholders relating to the Shares, (i) the transferring Holder shall comply with the requirements of such stockholders agreements or other agreements relating to any proposed transfer of the Offered Shares, and (ii) any proposed transferee that purchases Offered Shares shall enter into such stockholders agreements or other agreements with the Company and/or certain of the Company’s stockholders relating to the Offered Shares on the same terms and in the same capacity as the transferring Holder.  For the avoidance of doubt, in the event of any conflict between this Section 9(b) and the terms of that certain Right of First Refusal and Co-Sale Agreement between the Company and certain of its stockholders dated as of December 19, 2019, for so long as such agreement is in effect and as the same may be amended or amended and restated from time to time (the “Right of First Refusal and Co-Sale Agreement”), the terms of this Section 9(b) shall be subordinate to the terms of the Right of First Refusal and Co-Sale Agreement and the terms of the Right of First Refusal and Co-Sale Agreement shall govern.
15

(c)Company’s Right of Repurchase.
(i)Right of Repurchase for Unvested Shares Issued Upon the Exercise of an Option.  Upon a Termination Event, the Company shall have the right and option to repurchase from a Holder of Shares acquired upon exercise of a Stock Option which are still subject to a risk of forfeiture as of the Termination Event.  Such repurchase rights may be exercised by the Company within the later of (A) six months following the date of such Termination Event or (B) seven months after the acquisition of Shares upon exercise of a Stock Option.  The repurchase price shall be equal to the lower of the original per share price paid by the Holder, subject to adjustment as provided in Section 3(b) of the Plan, or the current Fair Market Value of such Shares as of the date the Company elects to exercise its repurchase rights.
(ii)Right of Repurchase With Respect to Restricted Stock.  Upon a Termination Event, the Company shall have the right and option to repurchase from a Holder of Shares received pursuant to a Restricted Stock Award any Shares that are still subject to a risk of forfeiture as of the Termination Event.  Such repurchase right may be exercised by the Company within six months following the date of such Termination Event.  The repurchase price shall be the lower of the original per share purchase price paid by the Holder, subject to adjustment as provided in Section 3(b) of the Plan, or the current Fair Market Value of such Shares as of the date the Company elects to exercise its repurchase rights.
(iii)Procedure.  Any repurchase right of the Company shall be exercised by the Company by giving the Holder written notice on or before the last day of the repurchase period of its intention to exercise such repurchase right.  Upon such notification, the Holder shall promptly surrender to the Company, free and clear of any liens or encumbrances, any certificates representing the Shares being purchased, together with a duly executed stock power for the transfer of such Shares to the Company.  Upon the Company’s receipt of the certificates from the Holder, the Company shall deliver to him, her or them a check for the applicable repurchase price; provided, however, that the Company may pay the repurchase price by offsetting and canceling any indebtedness then owed by the Holder to the Company.
(d)Drag Along Right. Capitalized terms used but not defined in this Section 9(d) have the meaning given to them in the Voting Agreement between the Company and certain of its stockholders made on or about the date of adoption of this Plan, as amended from time to time (“Voting Agreement”). In the event eligible stockholders or the Company determine to effect an Exit, a Holder of Shares, including any Permitted Transferee, shall be obligated to and shall upon the written request of the Company or the Accepting Requisite Holder:  (a) sell, transfer and deliver, or cause to be sold, transferred and delivered, to the Acquirer(s), his or her Shares (including for this purpose all of such Holder’s Shares that presently or as a result of any such transaction may be acquired upon the exercise of an Option (following the payment of the exercise price therefor)) on substantially the same terms applicable to the Accepting Requisite Holder (with appropriate adjustments to reflect the conversion of convertible securities, the redemption of redeemable securities and the exercise of exercisable securities as well as the relative preferences and priorities of preferred stock); and (b) execute and deliver such instruments of conveyance and transfer and take such other action, including voting such Shares in favor of any Exit proposed by the Accepting Requisite Holder and executing any purchase 
16

agreements, merger agreements, indemnity agreements, escrow agreements or related documents as the Accepting Requisite Holder or the Acquirer(s) may reasonably require in order to carry out the terms and provisions of this Section 9(d).
(e)Escrow Arrangement.
(i)Escrow.  In order to carry out the provisions of this Section 9 of this Plan more effectively, the Company shall hold any Shares issued pursuant to Awards granted under the Plan in escrow together with separate stock powers executed by the Holder in blank for transfer.  The Company shall not dispose of the Shares except as otherwise provided in this Plan. In the event of any repurchase by the Company, the Company is hereby authorized by the Holder, as the Holder’s attorney-in-fact, to date and complete the stock powers necessary for the transfer of the Shares being purchased and to transfer such Shares in accordance with the terms hereof.  At such time as any Shares are no longer subject to the Company’s repurchase and first refusal rights, the Company shall, at the written request of the Holder, deliver to the Holder a certificate representing such Shares with the balance of the Shares to be held in escrow pursuant to this Section.
(ii)Remedy.  Without limitation of any other provision of this Plan or other rights, in the event that a Holder or any other Person is required to sell a Holder’s Shares pursuant to the provisions of Sections 9(b) or (c) hereof and in the further event that he or she refuses or for any reason fails to deliver to the Company or its designated purchaser of such Shares the certificate or certificates evidencing such Shares together with a related stock power, the Company or such designated purchaser may deposit the applicable purchase price for such Shares with a bank designated by the Company, or with the Company’s independent public accounting firm, as agent or trustee, or in escrow, for such Holder or other Person, to be held by such bank or accounting firm for the benefit of and for delivery to him, her, them or it, and/or, in its discretion, pay such purchase price by offsetting any indebtedness then owed by such Holder as provided above.  Upon any such deposit and/or offset by the Company or its designated purchaser of such amount and upon notice to the Person who was required to sell the Shares to be sold pursuant to the provisions of Sections 9(b) or (c), such Shares shall at such time be deemed to have been sold, assigned, transferred and conveyed to such purchaser, such Holder shall have no further rights thereto (other than the right to withdraw the payment thereof held in escrow, if applicable), and the Company shall record such transfer in its stock transfer book or in any appropriate manner.
(f)Lockup Provision.  If requested by the Company, a Holder shall not sell or otherwise transfer or dispose of any Shares (including, without limitation, pursuant to Rule 144 under the Securities Act) held by him or her for such period following the effective date of a public offering by the Company of Shares as the Company shall specify reasonably and in good faith.  If requested by the underwriter engaged by the Company, each Holder shall execute a separate letter confirming his or her agreement to comply with this Section.
(g)Adjustments for Changes in Capital Structure.  If, as a result of any reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in the Common Stock, the outstanding Shares are increased or decreased or are exchanged for a different number or kind of securities of the Company, the restrictions 
17

contained in this Section 9 shall apply with equal force to additional and/or substitute securities, if any, received by Holder in exchange for, or by virtue of his or her ownership of, Shares.
(h)Termination.  The terms and provisions of Section 9(b) and Section 9(c) (except for the Company’s right to repurchase Shares still subject to a risk of forfeiture upon a Termination Event) shall terminate upon the closing of the Company’s Initial Public Offering or upon consummation of any Sale Event, in either case as a result of which Shares are registered under Section 12 of the Exchange Act and publicly-traded on any national security exchange.
SECTION 10.TAX WITHHOLDING
(a)Payment by Grantee.  Each grantee shall, no later than the date as of which the value of an Award or of any Shares or other amounts received thereunder first becomes includable in the gross income of the grantee for income tax purposes, pay to the Company, or make arrangements satisfactory to the Committee regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld by the Company with respect to such income.  The Company and any Subsidiary shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee.  The Company’s obligation to deliver stock certificates (or evidence of book entry) to any grantee is subject to and conditioned on any such tax withholding obligations being satisfied by the grantee.
(b)Payment in Stock.  The Company’s required tax withholding obligation may be satisfied, in whole or in part, by the Company (i) withholding from Shares to be issued pursuant to an Award a number of Shares having an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount due or (ii) causing its transfer agent to sell a number of Shares with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount due and remitting the proceeds from such sale to the Company.
SECTION 11.SECTION 409A AWARDS.
To the extent that any Award is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A (a “409A Award”), the Award shall be subject to such additional rules and requirements as may be specified by the Committee from time to time.  In this regard, if any amount under a 409A Award is payable upon a “separation from service” (within the meaning of Section 409A) to a grantee who is considered a “specified employee” (within the meaning of Section 409A), then no such payment shall be made prior to the date that is the earlier of (i) six months and one day after the grantee’s separation from service, or (ii) the grantee’s death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties and/or additional tax imposed pursuant to Section 409A.  The Company makes no representation or warranty and shall have no liability to any grantee under the Plan or any other Person with respect to any penalties or taxes under Section 409A that are, or may be, imposed with respect to any Award.
SECTION 12.AMENDMENTS AND TERMINATION
The Board may, at any time, amend or discontinue the Plan and the Committee may, at any time, amend or cancel any outstanding Award for the purpose of satisfying changes in law or 
18

for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the consent of the holder of the Award.  The Committee may exercise its discretion to reduce the exercise price of outstanding Stock Options or effect repricing through cancellation of outstanding Stock Options and by granting such holders new Awards in replacement of the cancelled Stock Options.  To the extent determined by the Committee to be required either by the Code to ensure that Incentive Stock Options granted under the Plan are qualified under Section 422 of the Code or otherwise, Plan amendments shall be subject to approval by the Company stockholders entitled to vote at a meeting of stockholders. Nothing in this Section 12 shall limit the Board’s or Committee’s authority to take any action permitted pursuant to Section 3(c).  The Board reserves the right to amend the Plan and/or the terms of any outstanding Stock Options to the extent reasonably necessary to comply with the requirements of the exemption pursuant to paragraph (f)(4) of Rule 12h-1 of the Exchange Act.
SECTION 13.STATUS OF PLAN
With respect to the portion of any Award that has not been exercised and any payments in cash, Stock or other consideration not received by a grantee, a grantee shall have no rights greater than those of a general creditor of the Company unless the Committee shall otherwise expressly so determine in connection with any Award.
SECTION 14.GENERAL PROVISIONS
(a)No Distribution; Compliance with Legal Requirements. The Committee may require each person acquiring Shares pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the Shares without a view to distribution thereof.  No Shares shall be issued pursuant to an Award until all applicable securities law and other legal and stock exchange or similar requirements have been satisfied.  The Committee may require the placing of such stop-orders and restrictive legends on certificates for Stock and Awards as it deems appropriate.
(b)Delivery of Stock Certificates.  Stock certificates to grantees under the Plan shall be deemed delivered for all purposes when the Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company; provided that stock certificates to be held in escrow pursuant to Section 9 of the Plan shall be deemed delivered when the Company shall have recorded the issuance in its records.  Uncertificated Stock shall be deemed delivered for all purposes when the Company or a stock transfer agent of the Company shall have given to the grantee by electronic mail (with proof of receipt) or by United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company, notice of issuance and recorded the issuance in its records (which may include electronic “book entry” records).
(c)No Rights to Continued Services.  The adoption of the Plan and the grant of Awards do not confer upon any Person any right to continued employment or Service Relationship with the Company or any Subsidiary.
(d)Trading Policy Restrictions.  Option exercises and other Awards under the Plan shall be subject to the Company’s insider trading policy-related restrictions, terms and conditions 
19

as may be established by the Committee, or in accordance with policies set by the Committee, from time to time.
(e)Designation of Beneficiary.  Each grantee to whom an Award has been made under the Plan may designate a beneficiary or beneficiaries to exercise any Award on or after the grantee’s death or receive any payment under any Award payable on or after the grantee’s death. Any such designation shall be on a form provided for that purpose by the Committee and shall not be effective until received by the Committee.  If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the grantee’s estate.
(f)Legend.  Any certificate(s) representing the Shares shall carry substantially the following legend (and with respect to uncertificated Stock, the book entries evidencing such shares shall contain the following notation):
The transferability of this certificate and the shares of stock represented hereby are subject to the restrictions, terms and conditions (including repurchase and restrictions against transfers) contained in the SEMrush Holdings, Inc. Amended and Restated 2019 Stock Option and Grant Plan and any agreements entered into thereunder by and between the company and the holder of this certificate (a copy of which is available at the offices of the company for examination).
(g)Information to Holders of Options.  In the event the Company is relying on the exemption from the registration requirements of Section 12(g) of the Exchange Act contained in paragraph (f)(1) of Rule 12h-1 of the Exchange Act, the Company shall provide the information described in Rule 701(e)(3), (4) and (5) of the Securities Act to all holders of Options in accordance with the requirements thereunder.  The foregoing notwithstanding, the Company shall not be required to provide such information unless the optionholder has agreed in writing, on a form prescribed by the Company, to keep such information confidential.
(h)Third party rights. Each Founder and Investor (as defined in the Right of First Refusal and Co-Sale Agreement) and each Accepting Requisite Holder (as defined in the Voting Agreement) is a beneficiary of the provisions set out in Sections 9(b) and 9(d) which confer rights or benefits on him or it and may enforce such provisions against the Company, the Holder and their respective assigns, personal representatives and successors.
SECTION 15.EFFECTIVE DATE OF PLAN
The Plan shall become effective upon adoption by the Board and shall be approved by stockholders in accordance with applicable state law and the Company’s certificate of incorporation and bylaws within 12 months thereafter.  If the stockholders fail to approve the Plan within 12 months after its adoption by the Board of Directors, then any Awards granted or sold under the Plan shall be rescinded and no additional grants or sales shall thereafter be made under the Plan.  Subject to such approval by stockholders and to the requirement that no Shares may be issued hereunder prior to such approval, Stock Options and other Awards may be granted 
20

hereunder on and after adoption of the Plan by the Board.  No grants of Stock Options and other Awards may be made hereunder after the tenth anniversary of the date the Plan is adopted by the Board or the date the Plan is approved by the Company’s stockholders, whichever is earlier.
SECTION 16.GOVERNING LAW
This Plan, all Awards and any controversy arising out of or relating to this Plan and all Awards shall be governed by and construed in accordance with the General Corporation Law of the State of Delaware as to matters within the scope thereof, and as to all other matters shall be governed by and construed in accordance with the internal laws of the Commonwealth of Massachusetts, without regard to conflict of law principles that would result in the application of any law other than the law of the Commonwealth of Massachusetts.

INCENTIVE STOCK OPTION AGREEMENT
UNDER THE SEMRUSH HOLDINGS, INC. 2019
STOCK OPTION AND INCENTIVE PLAN
						
	Name of Optionee:
	_________________ (the “Optionee”)

		
	No. of Option Shares:
	_________ Shares

		
	Grant Date:	_________________
		
	Option Price Per Share:	$_________________ (the “Option Exercise Price”)
		
	Expiration Date:	_____________________ (the “(Expiration Date”)

Pursuant to the SEMrush Holdings, Inc. Amended and Restated 2019 Stock Option and Grant Plan (the “Plan”), SEMrush Holdings, Inc. a Delaware corporation (together with any successor, the “Company”), has granted to the individual named below, an option (the “Stock Option”) to purchase on or prior to the Expiration Date, or such earlier date as is specified herein, all or any part of the number of shares of Common Stock, par value $0.00001 per share (“Common Stock”), of the Company indicated below (the “Shares”), at the Option Exercise Price per share, subject to the terms and conditions set forth in this Incentive Stock Option Grant Notice (the “Grant Notice”), the attached Incentive Stock Option Agreement (the “Agreement”) and the Plan.  This Stock Option is intended to qualify as an “incentive stock option” as defined in Section 422(b) of the Internal Revenue Code of 1986, as amended from time to time (the “Code”).  To the extent that any portion of the Stock Option does not so qualify, it shall be deemed a non qualified stock option.  [This Stock Option replaces any and all options to purchase Non-voting Shares of SEMrush CY LTD (“SEMrush CY”) previously granted by SEMrush CY to the Optionee prior to the Grant Date (collectively, the “Prior Grant”).  By executing the Agreement and accepting the Stock Option, the Optionee hereby acknowledges and agrees that (i) the internal reorganization of SEMrush CY does not constitute an “M&A Event” or “Change in Control” for purposes of the Prior Grant, (ii) he/she shall have no further right to purchase any Non-Voting Shares of SEMrush CY, and (iii) he/she shall have no further right to receive any additional Non-Voting Shares or Shares in exchange for the Prior Grant.]
1.Vesting, Exercisability and Termination.
(a)No portion of this Stock Option may be exercised until such portion shall have vested and become exercisable.
(b)Except as set forth below, and subject to the determination of the Committee in its sole discretion to accelerate the vesting schedule hereunder, this Stock Option shall be vested and exercisable on the respective dates indicated below:
(i)This Stock Option shall initially be unvested and unexercisable.
(ii)This Stock Option shall vest and become exercisable in accordance with the Vesting Schedule set forth in the Grant Notice.

(c)Termination.  Except as may otherwise be provided by the Committee, if the Optionee’s Service Relationship is terminated, the period within which to exercise this Stock Option will be subject to earlier termination as set forth below (and if not exercised within such period, shall thereafter terminate subject, in each case, to Section 3(c) of the Plan):
(i)Termination Due to Death or Disability.  If the Optionee’s Service Relationship terminates by reason of such Optionee’s death or Disability, this Stock Option may be exercised, to the extent exercisable on the date of such termination, by the Optionee, the Optionee’s legal representative or legatee for a period of 12 months from the date of death or Disability or until the Expiration Date, if earlier.
(ii)Other Termination.  If the Optionee’s Service Relationship terminates for any reason other than death or Disability, and unless otherwise determined by the Committee, this Stock Option may be exercised, to the extent exercisable on the date of termination, for a period of 90 days from the date of termination or until the Expiration Date, if earlier; provided, however, if the Optionee’s Service Relationship is terminated for Cause, this Stock Option shall terminate immediately upon the date of such termination.
For purposes hereof, the Committee’s determination of the reason for termination of the Optionee’s Service Relationship shall be conclusive and binding on the Optionee and his or her representatives or legatees.  Any portion of this Stock Option that is not vested and exercisable on the date of termination of the Service Relationship shall terminate immediately and be null and void.
(d)It is understood and intended that this Stock Option is intended to qualify as an “incentive stock option” as defined in Section 422 of the Code to the extent permitted under applicable law.  Accordingly, the Optionee understands that in order to obtain the benefits of an incentive stock option under Section 422 of the Code, no sale or other disposition may be made of Shares for which incentive stock option treatment is desired within the one year period beginning on the day after the day of the transfer of such Shares to him or her, nor within the two year period beginning on the day after Grant Date of this Stock Option and further that this Stock Option must be exercised within three months after termination of employment as an employee (or 12 months in the case of death or disability) to qualify as an incentive stock option.  If the Optionee disposes (whether by sale, gift, transfer or otherwise) of any such Shares within either of these periods, he or she will notify the Company within 30 days after such disposition.  The Optionee also agrees to provide the Company with any information concerning any such dispositions required by the Company for tax purposes.  Further, to the extent this Stock Option and any other incentive stock options of the Optionee having an aggregate Fair Market Value in excess of $100,000 (determined as of the Grant Date) first become exercisable in any year, such options will not qualify as incentive stock options.
2.Exercise of Stock Option.
(a)The Optionee may exercise this Stock Option only in the following manner:  Prior to the Expiration Date, the Optionee may deliver a Stock Option exercise notice (an “Exercise Notice”) in the form of Appendix A hereto indicating his or her election to purchase some or all of the Shares with respect to which this Stock Option is then exercisable. 

Such notice shall specify the number of Shares to be purchased.  Payment of the purchase price may be made by one or more of the methods described in Section 5 of the Plan, subject to the limitations contained in such Section of the Plan, including the requirement that the Committee specifically approve in advance certain payment methods.
(b)Notwithstanding any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date.
3.Incorporation of Plan.  Notwithstanding anything herein to the contrary, this Stock Option shall be subject to and governed by all the terms and conditions of the Plan.
4.Transferability of Stock Option.  This Stock Option is personal to the Optionee and is not transferable by the Optionee in any manner other than by will or by the laws of descent and distribution or pursuant to a domestic relations order.  The Stock Option may be exercised during the Optionee’s lifetime only by the Optionee (or by the Optionee’s guardian or personal representative in the event of the Optionee’s incapacity).  The Optionee may elect to designate a beneficiary by providing written notice of the name of such beneficiary to the Company, and may revoke or change such designation at any time by filing written notice of revocation or change with the Company; such beneficiary may exercise the Optionee’s Stock Option in the event of the Optionee’s death to the extent provided herein.

Each Party hereby consents to service of process by registered mail at the address to which notices are to be given.  Each Party agrees that its, his or her submission to jurisdiction and its, his or her consent to service of process by mail is made for the express benefit of each other Party.

In light of the foregoing, until the first sale of Stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission under the Securities Act, the Optionee hereby unconditionally and irrevocably waives the Inspection Rights, whether such Inspection Rights would be exercised or pursued directly or indirectly pursuant to Section 220 or otherwise, and covenants and agrees never to directly or indirectly commence, voluntarily aid in any way, prosecute, assign, transfer, or cause to be commenced any claim, action, cause of action, or other proceeding to pursue or exercise the Inspection Rights.

Dispute Resolution.
Except as provided below, any dispute arising out of or relating to the Plan or the Shares, this Agreement, or the breach, termination or validity of the Plan, the Shares or this Agreement, shall be finally settled by binding arbitration conducted expeditiously in accordance with the J.A.M.S./Endispute Comprehensive Arbitration Rules and Procedures (the “J.A.M.S.

Sections 1 - 16, and judgment upon the award rendered by the arbitrators may be entered by any court having jurisdiction thereof.  The place of arbitration shall be Boston, Massachusetts.
The arbitration shall commence within 60 days of the date on which a written demand for arbitration is filed by any party hereto.  In connection with the arbitration proceeding, the arbitrator shall have the power to order the production of documents by each party and any third-party witnesses.  In addition, each party may take up to three depositions as of right, and the arbitrator may in his or her discretion allow additional depositions upon good cause shown by the moving party.

In connection with any arbitration, each party to the arbitration shall provide to the other, no later than seven business days before the date of the arbitration, the identity of all persons that may testify at the arbitration and a copy of all documents that may be introduced at the arbitration or considered or used by a party’s witness or expert.

The arbitrator shall not have power to award damages in excess of actual compensatory damages and shall not multiply actual damages or award punitive damages, and each party hereby irrevocably waives any claim to such damages.
The Company, the Grantee, each party to the Agreement and any other holder of Shares issued pursuant to this Agreement (each, a “Party”) covenants and agrees that such party will participate in the arbitration in good faith.  This Section 6 applies equally to requests for temporary, preliminary or permanent injunctive relief, except that in the case of temporary or preliminary injunctive relief any party may proceed in court without prior arbitration for the limited purpose of avoiding immediate and irreparable harm.
5

Each Party (i) hereby irrevocably submits to the jurisdiction of any United States District Court of competent jurisdiction for the purpose of enforcing the award or decision in any such proceeding, (ii) hereby waives, and agrees not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above named courts, that its property is exempt or immune from attachment or execution (except as protected by applicable law), that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court, and (iii) hereby waives and agrees not to seek any review by any court of any other jurisdiction which may be called upon to grant an enforcement of the judgment of any such court.  Each Party hereby consents to service of process by registered mail at the address to which notices are to be given.  Each Party agrees that its, his or her submission to jurisdiction and its, his or her consent to service of process by mail is made for the express benefit of each other Party.  Final judgment against any Party in any such action, suit or proceeding may be enforced in other jurisdictions by suit, action or proceeding on the judgment, or in any other manner provided by or pursuant to the laws of such other jurisdiction.
Waiver of Statutory Information Rights.  The Grantee understands and agrees that, but for the waiver made herein, the Grantee would be entitled, upon written demand under oath stating the purpose thereof, to inspect for any proper purpose, and to make copies and extracts from, the Company’s stock ledger, a list of its stockholders, and its other books and records, and the books and records of subsidiaries of the Company, if any, under the circumstances and in the manner provided in Section 220 of the General Corporation Law of Delaware (any and all such rights, and any and all such other rights of the Grantee as may be provided for in Section 220, the “Inspection Rights”). In light of the foregoing, until the first sale of Stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission under the Securities Act, the Grantee hereby unconditionally and irrevocably waives the Inspection Rights, whether such Inspection Rights would be exercised or pursued directly or indirectly pursuant to Section 220 or otherwise, and covenants and agrees never to directly or indirectly commence, voluntarily aid in any way, prosecute, assign, transfer, or cause to be commenced any claim, action, cause of action, or other proceeding to pursue or exercise the Inspection Rights. The foregoing waiver shall not affect any rights of a director, in his or her capacity as such, under Section 220. The foregoing waiver shall not apply to any contractual inspection rights of the Grantee under any other written agreement between the Grantee and the Company.

Premises 
2.1Demise and Lease of Premises 
Landlord hereby demises and leases to Tenant, and Tenant hereby hires and accepts from Landlord, the Premises in the Building, excluding exterior faces of exterior walls, the common stairways and stairwells, elevators and elevator walls, mechanical rooms, electric and telephone closets, janitor closets, and pipes, ducts, shafts, conduits, wires and appurtenant fixtures serving exclusively or in common other parts of the Building, and if the Premises includes less than the entire rentable area of any floor, excluding the common corridors, elevator lobbies and restrooms located on such floor. Tenant hereby agrees with Landlord that, upon the written request of Landlord made from time to time, but in no event less than thirty (30) days in advance, Tenant shall relocate from the Premises then demised to Tenant under this Lease (the “Original Premises”) to other premises (the “Relocated Premises”) within the Building or the buildings located at the Prudential Center known as 800 Boylston Street, 111 Huntington Avenue, 101 Huntington Avenue or 888 Boylston Street and upon such relocation the Relocated Premises shall become the premises demised under this Lease and wherever the term “Premises” is used herein the same thereafter shall mean and refer to the Relocated Premises. Landlord, at its sole cost and expense, shall perform the partitioning of the Relocated Premises and shall place the same into substantially equivalent condition to that in which the Original Premises were in prior to such relocation, and Landlord shall also reimburse Tenant for Tenant’s reasonable out-ofpocket moving expenses in so relocating to the Relocated Premises upon billing therefor from Tenant, which billing shall include reasonable evidence thereof in the form of paid invoices, receipts and the like. Tenant shall not be required to vacate the Original Premises and to relocate to the Relocated Premises until the Relocated Premises shall be substantially complete subject to punch list items and items of long lead time. Upon any such relocation the Tenant shall enter into an amendment to this Lease confirming such relocation, but the Tenant’s failure to enter into such amendment shall not affect in any manner the relocation of the Premises demised under this Lease from the Original Premises to the Relocated Premises.  
2.2Appurtenant Rights and Reservations 
Subject to Landlord’s or any other PruOwner’s right to change or alter any of the following in Landlord’s discretion as herein provided, Tenant shall have, as appurtenant to the Premises, the non-exclusive right to use in common with others, but not in a manner or extent that would materially interfere with the normal operation and use of the Building as a multi-tenant office building and subject to reasonable rules of general applicability to tenants of the Building from time to time made by Landlord or any other PruOwner of which Tenant is given notice: (a) the common lobbies, corridors, stairways, and elevators of the Building, and the pipes, ducts, shafts, conduits, wires and appurtenant meters and equipment serving the Premises in common with others, (b) the loading areas serving the Building and the common walkways and driveways necessary for access to the Building, (c) if the Premises include less than the entire rentable floor area of any floor, the common restrooms, 

corridors and elevator lobby of such floor and (d) the plazas and other common areas of the Prudential Center as Landlord or any other PruOwner makes the same available from time to time; and no other appurtenant rights and easements. Notwithstanding anything to the contrary herein, Landlord has no obligation to allow any particular telecommunication service provider to have access to the Building or to the Premises. If Landlord permits such access, Landlord may condition such access upon the payment to Landlord by the service provider of fees assessed by Landlord in its sole discretion. 
Landlord reserves for its benefit and the benefit of any other PruOwner the right from time to time, without unreasonable interference with Tenant’s use: (a) to install, use, maintain, repair, replace and relocate for service to the Premises and other parts of the Building, or either, pipes, ducts, conduits, wires and appurtenant fixtures, wherever located in the Premises or the Building, and (b) to alter or relocate any other common facility, provided that substitutions are substantially equivalent or better. Installations, replacements and relocations referred to in clause (a) above shall be located so far as practicable in the central core area of the Building, above ceiling surfaces, below floor surfaces or within perimeter walls of the Premises. Except in the case of emergencies or for normal cleaning and maintenance operations, Landlord agrees to use all reasonable efforts to give, or cause such PruOwner to give, Tenant reasonable advance notice of any of the foregoing activities which require work in the Premises. 
Landlord reserves and excepts for its benefit and the benefit of any other PruOwner all rights of ownership and use in all respects outside the Premises, including without limitation, the Building and all other structures and improvements and plazas and common areas in the Prudential Center, except that at all times during the Lease Term Tenant shall have a reasonable means of access from a public street to the Premises. Without limitation of the foregoing reservation of rights by Landlord, it is understood that in its sole discretion Landlord or any other PruOwner, as the case may be, shall have the right to change and rearrange the plazas and other common areas, to change, relocate and eliminate facilities therein, to erect new buildings thereon, to permit the use of or lease all or part thereof for exhibitions and displays and to sell, lease or dedicate all or part thereof to public use; and further that Landlord or any other PruOwner, as the case may be, shall have the right to make changes in, additions to and eliminations from the Building and other structures and improvements in the Prudential Center, the Premises excepted; provided however that Tenant, its employees, agents, clients, customers, and invitees shall at all times have reasonable access to the Building and Premises. Subject to (i) Tenant’s compliance with Landlord's reasonable security program for the Building, and (ii) temporary interruption resulting from fire, casualty, maintenance activity, the actions of governmental authorities and other conditions not reasonably within Landlord’s control, Tenant shall have access to the Premises 24 hours per day, 365 days per year, except that Landlord is not under any obligation to permit individuals without proper building identification and satisfaction of Building rules and regulations to enter the Building after 6:00 p.m. or on weekends or holidays. 
ARTICLE III 
Lease Term 
3.1Term 
The Term of this Lease shall be the period specified in Section 1.1 hereof as the “Lease Term,” unless sooner terminated as herein provided. 
In the case where the Premises are to be delivered in their AS-IS condition, the day on which the Premises are delivered by Landlord to Tenant shall be the date on which the Landlord delivers the Premises to Tenant free and clear of all other tenants and occupants. In the case where the Landlord is to perform work to the Premises as provided in Article IV, the Premises shall be considered delivered by the Landlord to the Tenant on the day when the Premises are deemed to be substantially complete, as defined in Article IV.  
As soon as may be convenient after the Commencement Date has been determined, Landlord and Tenant agree to join with each other in the execution, in the form of Exhibit E hereto, of a written Declaration Affixing the Commencement Date of Lease in which the Commencement Date and specified Lease Term shall be stated. If Tenant shall fail to execute such Declaration Affixing the Commencement Date of Lease, the Commencement Date and Lease Term shall be as reasonably determined by Landlord in accordance with the terms of this Lease.  

ARTICLE IV 
Condition of Premises; Alterations 
4.1Landlord’s Work 
Landlord shall deliver the Premises to Tenant in the configuration depicted in the plan attached hereto as Exhibit B (excluding work identified in Exhibit B to be performed by Tenant). Landlord shall perform the following work in the Premises at Landlord’s sole cost and expense (the “Landlord’s Work”): (i) re-paint the Premises; and (ii) re-carpet the Premises.  At the direction of Tenant, and at Tenant’s sole cost and expense, Landlord shall paint select locations of the Premises, as determined by Landlord, with “IdeaPaint.” Subject to obtaining the Landlord’s consent in accordance with Article IX, Tenant may, at Tenant’s sole cost and expense, perform the following additional work, to be performed by a contractor approved by Landlord (the “Tenant’s Work”): (i) install new doors; (ii) install additional lighting; (iii) install marker wallpaper; and (iv) install additional cabling.  Tenant’s Work shall be considered “alterations” for purposes of this Lease and shall be subject to the provisions of Article IX.  
Landlord shall use reasonable efforts to substantially complete the Landlord’s Work by December 16, 2018.  Landlord shall use reasonable efforts to notify Tenant, orally or in writing, of any circumstances of which Landlord is aware that have caused or may cause a delay in the substantial completion of the Landlord’s Work.  Notwithstanding anything to the contrary herein, Landlord’s Work shall become part of the Premises and shall become the property of Landlord and remain upon the Premises as a part thereof upon the expiration or earlier termination of the Lease Term. 
4.2As-Is Condition 
Except for Landlord’s Work, Tenant shall accept the Premises in their as-is condition without any obligation on Landlord’s part to perform any additions, alterations, improvements, demolition or other work therein or pertaining thereto.  Without limiting the generality of the foregoing, Tenant shall be responsible, at its sole cost and expense, for the installation of all of its furniture, tel-data wiring and security systems, and for all of its moving expenses. 
ARTICLE V 
Annual Fixed Rent and Electricity  
5.1Fixed Rent 
Tenant agrees to pay to Landlord, on the Rent Commencement Date, and thereafter monthly, in advance, on the first day of each and every calendar month during the Original Lease Term, a sum equal to one-twelfth (1/12th) of the Annual Fixed Rent specified in Section 1.1 hereof. Until notice of some other designation is given, fixed rent and all other charges for which provision is herein made shall be paid by remittance to or for the order of Boston Properties Limited Partnership, as agent of Landlord. All remittances received by BOSTON PROPERTIES LIMITED PARTNERSHIP, as agent as aforesaid, or by any subsequently designated recipient, shall be treated as a payment to Landlord.  
Annual Fixed Rent for any partial month shall be paid by Tenant to Landlord at such rate on a pro rata basis, and, if the Rent Commencement Date shall be other than the first day of a calendar month, the first payment of Annual Fixed Rent which Tenant shall make to Landlord shall be a payment equal to a proportionate part of such monthly Annual Fixed Rent for the partial month from the Rent Commencement Date to the first day of the succeeding calendar month. 
Additional Rent payable by Tenant on a monthly basis, as elsewhere provided in this Lease, likewise shall be prorated, and the first payment on account thereof shall be determined in similar fashion and shall commence on the Rent Commencement Date and other provisions of this Lease calling for monthly payments shall be read as incorporating this undertaking by Tenant. 
Notwithstanding that the payment of Annual Fixed Rent payable by Tenant to Landlord shall not commence until the Rent Commencement Date, Tenant shall be subject to, and shall comply with, all other provisions of 

this Lease as and at the times provided in this Lease. The Annual Fixed Rent and all other charges for which provision is made in this Lease shall be paid by Tenant to Landlord without setoff, deduction or abatement. 
5.2Payment of Electricity Charges 
The Premises shall be separately metered for electricity and Tenant shall use a meter assigned to Tenant in order to monitor electricity usage in the Premises.  Commencing as of the Rent Commencement Date, Tenant shall be responsible for the cost of all electricity consumed within the Premises and shall pay all such electricity charges directly to the supplier of the same. Tenant’s failure to make payment when due to the utility company shall be considered to be a failure in the payment of rent hereunder for which Landlord shall have all its rights and remedies under this Lease and at law and in equity.  
ARTICLE VI 
Taxes 
6.1Definitions 
With reference to the real estate taxes referred to in this Article VI, it is agreed that terms used herein are defined as follows: 
(a)“Tax Year” means the 12-month period beginning July 1 each year during the Lease Term or if the appropriate Governmental tax fiscal period shall begin on any date other than July 1, such other date. 
(b)“Landlord’s Tax Expenses Allocable to the Premises” means the same proportion of Landlord’s Tax Expenses as Rentable Floor Area of Tenant’s Premises bears to 95% of the Rentable Floor Area of the Building. 
(c)“Landlord’s Tax Expenses” with respect to any Tax Year means the aggregate “real estate taxes” (hereinafter defined) with respect to that Tax Year, reduced by any net abatement receipts with respect to that Tax Year. 
(d)“Real estate taxes” means all taxes and special assessments of every kind and nature and user fees and other like fees assessed by any governmental authority (including, but not limited to, any tax, assessment or charge resulting from the creation of a special improvement district) on, or allocable to the Building and reasonable expenses of and fees for any formal or informal proceedings for negotiation or abatement of taxes (collectively, “Abatement Expenses”), which Abatement Expenses shall be excluded from Base Taxes. The amount of special taxes or special assessments to be included shall be limited to the amount of the installment (plus any interest other than penalty interest payable thereon) of such special tax or special assessment required to be paid during the year in respect of which such taxes are being determined. There shall be excluded from such taxes all income, estate, succession, inheritance and transfer taxes; provided, however, that if at any time during the Lease Term the present system of ad valorem taxation of real property shall be changed so that in lieu of, or in addition to, the whole or any part of the ad valorem tax on real property, there shall be assessed on Landlord a capital levy or other tax on the gross rents received with respect to the Building, or a Federal, State, County, Municipal, or other local income, franchise, excise or similar tax, assessment, levy or charge (distinct from any now in effect in the jurisdiction in which the Prudential Center is located) measured by or based, in whole or in part, upon any such gross rents, then any and all of such taxes, assessments, levies or charges, to the extent so measured or based, shall be deemed to be included within the term “real estate taxes” but only to the extent that the same would be payable if the Building, were the only property of Landlord. To the extent that the Building is not separately assessed for real estate tax purposes, but is assessed as part of a larger parcel, then the Landlord shall make a reasonable allocation as to the amount of the real estate taxes that should be allocated to the Building for the purposes of determination of the Tenant’s share of increases in real estate taxes under this 

Lease. The Landlord’s allocation, if made in good faith, shall be final. For the purposes of this Lease, real estate taxes shall include any payment in lieu of taxes or any payments made under Chapter 121A of the Massachusetts General Laws or any similar law. 
(e)“Base Taxes” means Landlord’s Tax Expenses (hereinbefore defined) for fiscal tax year 2019 (that is the period beginning July 1, 2018 and ending June 30, 2019). 
(f)“Base Taxes Allocable to the Premises” means the same proportion of Base Taxes as the Rentable Floor Area of Tenant’s Premises bears to 95% of the Total Rentable Floor Area of the Building. 
(g)If during the Lease Term the Tax Year is changed by applicable law to less than a full 12-month period, the Base Taxes and Base Taxes Allocable to the Premises shall each be proportionately reduced. 
6.2Tenant’s Share of Real Estate Taxes 
If with respect to any full Tax Year or fraction of a Tax Year falling within the Lease Term Landlord’s Tax Expenses Allocable to the Premises for a full Tax Year exceed Base Taxes Allocable to the Premises or for any such fraction of a Tax Year exceed the corresponding fraction of Base Taxes Allocable to the Premises (such amount being hereinafter referred to as the “Tax Excess”), then Tenant shall pay to Landlord, as Additional Rent, the amount of such Tax Excess. Payments by Tenant on account of the Tax Excess shall be made monthly at the time and in the fashion herein provided for the payment of Annual Fixed Rent. The amount so to be paid to Landlord shall be an amount from time to time reasonably estimated by Landlord to be sufficient to provide Landlord, in the aggregate, a sum equal to the Tax Excess, at least ten (10) days before the day on which tax payments by Landlord would become delinquent. Not later than ninety (90) days after Landlord’s Tax Expenses Allocable to the Premises are determinable for the first such Tax Year or fraction thereof and for each succeeding Tax Year or fraction thereof during the Lease Term, Landlord shall render Tenant a statement in reasonable detail certified by a representative of Landlord showing for the preceding year or fraction thereof, as the case may be, real estate taxes allocated to the Building, abatements and refunds, if any, of any such taxes and assessments, expenditures incurred in seeking such abatement or refund, the amount of the Tax Excess, the amount thereof already paid by Tenant and the amount thereof overpaid by, or remaining due from, Tenant for the period covered by such statement. Within thirty (30) days after the receipt of such statement, Tenant shall pay any sum remaining due. Any balance shown as due to Tenant shall be credited against Annual Fixed Rent next due, or refunded to Tenant if the Lease Term has then expired and Tenant has no further obligation to Landlord. Expenditures for legal fees and for other expenses incurred in obtaining an abatement or refund may be charged against the abatement or refund before the adjustments are made for the Tax Year. Only Landlord shall have the right to institute tax reduction or other proceedings to reduce real estate taxes or the valuation of the Building.  
To the extent that real estate taxes shall be payable to the taxing authority in installments with respect to periods less than a Tax Year, the statement to be furnished by Landlord shall be rendered and payments made on account of such installments. 
ARTICLE VII  
Landlord’s Repairs and Services and Tenant’s Escalation Payments 
7.1Structural Repairs 
Except for (a) normal and reasonable wear and use and (b) damage caused by fire or casualty and by eminent domain, Landlord shall, throughout the Lease Term, subject to provisions for reimbursement by Tenant as contained in Section 7.5, keep and maintain, or cause to be kept and maintained, in good order, condition and repair the following portions of the Building: the structural portions of the roof, the exterior and load bearing walls, the foundation, the structural columns and floor slabs and other structural elements of the Building; provided however, that Tenant shall pay to Landlord, as Additional Rent, the cost of any and all such repairs 

which may be required as a result of repairs, alterations, or installations made by Tenant or any subtenant, assignee, licensee or concessionaire of Tenant or any agent, servant, employee or contractor of any of them or to the extent of any loss, destruction or damage caused by the omission or negligence of Tenant, any assignee or subtenant or any agent, servant, employee, customer, visitor or contractor of any of them.  
7.2Other Repairs to be Made by Landlord 
Except for (a) normal and reasonable wear and use and (b) damage caused by fire or casualty and by eminent domain, and except as otherwise provided in this Lease, and subject to provisions for reimbursement by Tenant as contained in Section 7.5, Landlord agrees to keep and maintain, or cause to be kept and maintained, in good order, condition and repair the common areas and facilities of the Building, including heating, ventilating, air conditioning, plumbing and other Building systems equipment servicing the Premises, except that Landlord shall in no event be responsible to Tenant for (a) the condition of glass in and about the Premises (other than for glass in exterior walls for which Landlord shall be responsible unless the damage thereto is attributable to Tenant’s negligence or misuse, in which event the responsibility therefor shall be Tenant’s), or (b) any condition in the Premises or the Building caused by any act or neglect of Tenant or any agent, employee, contractor, assignee, subtenant, licensee, concessionaire or invitee of Tenant. Without limitation, Landlord shall not be responsible to make any improvements or repairs to the Building or the Premises other than as expressly provided in Section 7.1 or in this Section 7.2, unless expressly otherwise provided in this Lease. 
7.3Services to be Provided by Landlord 
In addition, and except as otherwise provided in this Lease and subject to (i) provisions for reimbursement by Tenant as contained in Section 7.5 and in Exhibit C hereto and (ii) Tenant’s responsibilities in regard to electricity as provided in Section 5.2, Landlord agrees to furnish services, utilities, facilities and supplies as set forth in said Exhibit C equal in quality comparable to those customarily provided by landlords in high quality buildings in Boston. In addition, Landlord agrees to furnish, at Tenant’s expense, reasonable additional Building operation services which are usual and customary in similar Class A office buildings in Boston, Massachusetts, and such additional special services as may be mutually agreed upon by Landlord and Tenant, upon reasonable and equitable rates from time to time established by Landlord. Tenant agrees to pay to Landlord, as Additional Rent, the cost of any such additional Building services requested by Tenant and for the cost of any additions, alterations, improvements or other work performed by Landlord in the Premises at the request of Tenant within thirty (30) days after being billed therefor. 
7.4Operating Costs Defined 
“Operating Expenses Allocable to the Premises” means the same proportion of the Operating Expenses for the Building (as hereinafter defined) as Rentable Floor Area of the Premises bears to 95% of the Total Rentable Floor Area of the Building. “Base Operating Expenses” means Operating Expenses for the Building for calendar year 2018 (that is the period beginning January 1, 2018 and ending December 31, 2018). Base Operating Expenses shall not include (i) market-wide cost increases due to extraordinary circumstances, including but not limited to, Force Majeure (as defined in Section 14.1), boycotts, strikes, conservation surcharges, security concerns, embargoes or shortages and (ii) the cost of any “Permitted Capital Expenditures” (as defined hereinbelow in this Section 7.4). “Base Operating Expenses Allocable to the Premises” means the same proportion of Base Operating Expenses as the Rentable Floor Area of Tenant’s Premises bears to 95% of the Total Rentable Floor Area of the Building. “Operating Expenses for the Building” means the cost of operation of the Building and the Building’s share of the cost of operating other areas of the Prudential Center as more specifically provided below in Section 7.4, including those incurred in discharging the obligations under Sections 7.2 and 7.3; however there shall be excluded from the Operating Expenses for the Building the cost of operation of the Garage. In addition, such costs shall exclude payments of debt service and any other mortgage charges, brokerage commissions, real estate taxes (to the extent paid pursuant to Section 6.2 hereof), and costs of special services rendered to tenants (including Tenant) for which a separate charge is made, but shall include, without limitation: 

(a)compensation, wages and all fringe benefits, workmen’s compensation insurance premiums and payroll taxes paid to, for or with respect to all persons for their services in the operating, maintaining, managing, insuring or cleaning of the Building or the Prudential Center; 
(b)payments under service contracts with independent contractors for operating, maintaining or cleaning of the Building or the Prudential Center; 
(c)steam, water, sewer, gas, oil, electricity and telephone charges (excluding such utility charges separately chargeable to tenants for additional or separate services and electricity charges paid by Tenant in the manner set forth in Section 5.2) and costs of maintaining letters of credit or other security as may be required by utility companies as a condition of providing such services; 
(d)cost of maintenance, cleaning and repairs and replacements(other than repairs reimbursed from contractors under guarantees); 
(e)cost of snow removal and care of landscaping; 
(f)cost of building and cleaning supplies and equipment; 
(g)premiums for insurance carried with respect to the Building or Prudential Center (including, without limitation, liability insurance, insurance against loss in case of fire or casualty and of monthly installments of Annual Fixed Rent and any Additional Rent which may be due under this Lease and other leases of space in the Building for not more than twelve (12) months in the case of both Annual Fixed Rent and Additional Rent and, if there be any first mortgage on the Building, including such insurance as may be required by the holder of such first mortgage);  
(h)management fees at reasonable rates for self-managed buildings consistent with the type of occupancy and the services rendered;  
(i)the Building’s share (as reasonably determined by Landlord) of Operating Expenses for the Building (as herein defined in this Section 7.4) related to the operation of the open areas, public areas and amenities, plazas, common areas, facilities and other non-leasable areas of the Prudential Center and other mixed use common area maintenance costs incurred by Landlord or any other PruOwner and allocated to the Building and any shuttle buses and other like amenities, for use of tenants of the Building either alone or in common with tenants of other buildings in the Prudential Center; 
(j)depreciation for capital improvements made by Landlord during the Lease Term (x) to reduce Operating Expenses if Landlord reasonably shall have determined that the annual reduction in Operating Expenses shall exceed depreciation therefor or (y) to comply with Legal Requirements (the capital expenditures described in subsections (x) and (y) being hereinafter referred to as “Permitted Capital Expenditures”) plus, in the case of both (x) and (y), an interest factor, reasonably determined by Landlord, as being the interest rate then charged for long term mortgages by institutional lenders on like properties within the general locality in which the Building is located, and depreciation in the case of both (x) and (y) shall be determined by dividing the original cost of such capital expenditure by the number of years of useful life of the capital item acquired, which useful life shall be determined reasonably by Landlord in accordance with generally accepted accounting principles and practices in effect at the time of acquisition of the capital item; provided, however, if Landlord reasonably concludes on the basis of engineering estimates that a particular capital expenditure will effect savings in other Operating Expenses, including, without limitation, energy related costs, and that such projected savings will, on an annual basis (“Projected Annual Savings”), exceed the annual depreciation therefor, then and in such event the amount of depreciation for such capital expenditure shall be increased to an amount equal to the Projected Annual Savings; 

and in such circumstance, the increased depreciation (in the amount of the Projected Annual Savings) shall be made for such period of time as it would take to fully amortize the cost of the item in question, together with interest thereon at the interest rate as aforesaid in equal monthly payments, each in the amount of 1/12th of the Projected Annual Savings, with such payment to be applied first to interest and the balance to principal;  
(k)all costs of applying and reporting for the Building or any part thereof to seek or maintain certification under the U.S. EPA’s Energy Star® rating system, the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) rating system or a similar system or standard; and 
(l)all other reasonable and necessary expenses paid in connection with the operating, cleaning and maintenance of the Building or the Prudential Center or said common areas and facilities and properly chargeable against income.  
Notwithstanding the foregoing, in determining the amount of Operating Expenses for the Building for any calendar year or portion thereof falling within the Lease Term, if less than ninety-five percent (95%) of the Total Rentable Floor Area of the Building shall have been occupied by tenants at any time during the period in question, then, at Landlord’s election, those components of Operating Expenses for the Building that vary based on occupancy for such period shall be adjusted to equal the amount such components of Operating Expenses for the Building would have been for such period had occupancy been ninety-five percent (95%) throughout such period. 
7.5Tenant’s Escalation Payments 
(A)If with respect to any calendar year falling within the Lease Term, or fraction of a calendar year falling within the Lease Term at the beginning or end thereof, the Operating Expenses Allocable to the Premises (as defined in Section 7.4) for a full calendar year exceed Base Operating Expenses Allocable to the Premises (as defined in Section 7.4) or for any such fraction of a calendar year exceed the corresponding fraction of Base Operating Expenses Allocable to the Premises (such amount being hereinafter referred to as the “Operating Cost Excess”), then Tenant shall pay to Landlord, as Additional Rent, on or before the thirtieth (30th) day following receipt by Tenant of the statement referred to below in this Section 7.5, the amount of such excess.  
(B)Payments by Tenant on account of the Operating Cost Excess shall be made monthly at the time and in the fashion herein provided for the payment of Annual Fixed Rent. The amount so to be paid to Landlord shall be an amount from time to time reasonably estimated by Landlord to be sufficient to cover, in the aggregate, a sum equal to the Operating Cost Excess for each calendar year during the Lease Term. 
(C)No later than one hundred twenty (120) days after the end of the first calendar year or fraction thereof ending December 31 and of each succeeding calendar year during the Lease Term or fraction thereof at the end of the Lease Term, Landlord shall render Tenant a statement in reasonable detail and according to usual accounting practices certified by a representative of Landlord, showing for the preceding calendar year or fraction thereof, as the case may be, the Operating Expenses for the Building and the Operating Expenses Allocable to the Premises. Said statement to be rendered to Tenant also shall show for the preceding year or fraction thereof, as the case may be, the amounts already paid by Tenant on account of Operating Cost Excess and the amount of Operating Cost Excess remaining due from, or overpaid by, Tenant for the year or other period covered by the statement. 
If such statement shows a balance remaining due to Landlord, Tenant shall pay same to Landlord on or before the thirtieth (30th) day following receipt by Tenant of said statement. Any balance shown as due to Tenant shall be credited against Annual Fixed Rent next due, or refunded to Tenant if the Lease Term has then expired and Tenant has no further obligation to Landlord. 

Any payment by Tenant for the Operating Cost Excess shall not be deemed to waive any rights of Tenant to claim that the amount thereof was not determined in accordance with the provisions of this Lease. 
7.6No Damage 
Landlord shall not be liable to Tenant for any compensation or reduction of rent by reason of inconvenience or annoyance or for loss of business arising from the necessity of Landlord or its agents entering the Premises for any purposes in this Lease authorized, or for repairing the Premises or any portion of the Building or Prudential Center however the necessity may occur. In case Landlord is prevented or delayed from making any repairs, alterations or improvements, or furnishing any services or performing any other covenant or duty to be performed on Landlord’s part, by reason of any cause reasonably beyond Landlord’s control, including, without limitation, by reason of Force Majeure (as defined in Section 14.1 hereof) or for any cause due to any act or neglect of Tenant or Tenant’s servants, agents, employees, licensees or any person claiming by, through or under Tenant, Landlord shall not be liable to Tenant therefor, nor, except as expressly otherwise provided in this Lease, shall Tenant be entitled to any abatement or reduction of rent by reason thereof, or right to terminate this Lease, nor shall the same give rise to a claim in Tenant’s favor that such failure constitutes actual or constructive, total or partial, eviction from the Premises.
Landlord reserves the right to stop any service or utility system, when necessary by reason of accident or emergency, or until necessary repairs have been completed; provided, however, that in each instance of stoppage, Landlord shall exercise reasonable diligence to eliminate the cause thereof. Except in case of emergency repairs, Landlord will give Tenant at least twenty-four (24) hours’ notice of any contemplated stoppage and will use reasonable efforts to avoid unnecessary inconvenience to Tenant by reason thereof. 
ARTICLE VIII 
Tenant’s Repairs 
8.1Tenant’s Repairs and Maintenance 
Tenant covenants and agrees that, from and after the date that possession of the Premises is delivered to Tenant and until the end of the Lease Term, Tenant will keep neat and clean and maintain in good order, condition and repair the Premises and every part thereof, excepting only for those repairs for which Landlord is responsible under the terms of Article VII of this Lease and damage by fire or casualty and as a consequence of the exercise of the power of eminent domain. Tenant shall not permit or commit any waste, and Tenant shall be responsible for the cost of repairs which may be made necessary by reason of damages to common areas in the Building or Prudential Center by Tenant, Tenant’s agents, employees, contractors, sublessees, licensees, concessionaires or invitees. Tenant shall maintain all its equipment, furniture and furnishings in good order and repair. 
If repairs are required to be made by Tenant pursuant to the terms hereof, Landlord may demand that Tenant make the same forthwith, and if Tenant refuses or neglects to commence such repairs and complete the same with reasonable dispatch after such demand, Landlord may (but shall not be required to do so) make or cause such repairs to be made and shall not be responsible to Tenant for any loss or damage that may accrue to Tenant’s stock or business by reason thereof. If Landlord makes or causes such repairs to be made, Tenant agrees that Tenant will forthwith on demand, pay to Landlord as Additional Rent the cost thereof together with interest thereon at the rate specified in Section 16.21, and if Tenant shall default in such payment, Landlord shall have the remedies provided for non-payment of rent or other charges payable hereunder. 

ARTICLE IX 
Alterations 
9.1Landlord’s Approval 
Tenant covenants and agrees not to make alterations, additions or improvements to the Premises, whether before or during the Lease Term, except in accordance with plans and specifications therefor first approved by Landlord in writing, which approval shall not be unreasonably withheld or delayed. However, Landlord’s determination of matters relating to aesthetic issues relating to alterations, additions or improvements which are visible outside the Premises shall be in Landlord’s sole discretion. Without limiting such standard, Landlord shall not be deemed unreasonable: 
(a)for withholding approval of any alterations, additions or improvements which (i) in Landlord’s opinion might affect any structural or exterior element of the Building, any area or element outside of the Premises or any facility or base building mechanical system serving any area of the Building outside of the Premises, or (ii) involve or affect the exterior design, size, height or other exterior dimensions of the Building, or (iii) enlarge the Rentable Floor Area of the Premises, or (iv) are inconsistent, in Landlord’s judgment, with alterations satisfying Landlord’s standards for new alterations in the Building, or (v) will require unusual expense to readapt the Premises to normal office use on Lease termination or increase the cost of construction or of insurance or taxes on the Building or of the services called for by Section 7.3 unless Tenant first gives assurance acceptable to Landlord for payment of such increased cost and that such readaptation will be made prior to such termination without expense to Landlord. 
(b)for making its approval conditional on Tenant’s agreement to restore the Premises to its condition prior to such alteration, addition, or improvement at the expiration or earlier termination of the Lease Term.  
Landlord’s review and approval of any such plans and specifications and consent to perform work described therein shall not be deemed an agreement by Landlord that such plans, specifications and work conform with applicable Legal Requirements and requirements of insurers of the Building and the other requirements of the Lease with respect to Tenant’s insurance obligations (herein called “Insurance Requirements”) nor deemed a waiver of Tenant’s obligations under this Lease with respect to applicable Legal Requirements and Insurance Requirements nor impose any liability or obligation upon Landlord with respect to the completeness, design sufficiency or compliance of such plans, specifications and work with applicable Legal Requirements and Insurance Requirements. Further, Tenant acknowledges that Tenant is acting for its own benefit and account, and that Tenant shall not be acting as Landlord’s agent in performing any work in the Premises, accordingly, no contractor, subcontractor or supplier shall have a right to lien Landlord’s interest in the Prudential Center in connection with any such work. Within 30 days after receipt of an invoice from Landlord, Tenant shall pay to Landlord, as a fee for Landlord’s review of any plans or work (including any review of plans or work relating to any assignment or subletting), as Additional Rent, an amount equal to the sum of : (i) $150.00 per hour, plus (ii) reasonable third party expenses incurred by Landlord to review Tenant’s plans and Tenant’s work.  
9.2Conformity of Work 
Tenant covenants and agrees that any alterations, additions, improvements or installations made by it to or upon the Premises shall be done in a good and workmanlike manner and in compliance with all applicable Legal Requirements and Insurance Requirements now or hereafter in force, that materials of first and otherwise good quality shall be employed therein, that the structure of the Building shall not be endangered or impaired thereby and that the Premises shall not be diminished in value thereby. 

9.3Performance of Work, Governmental Permits and Insurance 
All of Tenant’s alterations and additions and installation of furnishings shall be coordinated with any work being performed by or for Landlord and in such manner as to maintain harmonious labor relations and not to damage the Building or Prudential Center or interfere with Building construction or operation and, except for installation of furnishings, shall be performed by Landlord’s general contractor or by contractors or workers first approved by Landlord. Except for work by Landlord’s general contractor, Tenant shall procure all necessary governmental permits before making any repairs, alterations, other improvements or installations. Tenant agrees to save harmless and indemnify Landlord from any and all injury, loss, claims or damage to any person or property occasioned by or arising out of the doing of any such work whether the same be performed prior to or during the Lease Term. At Landlord’s election, Tenant shall cause its contractor to maintain a payment and performance bond in such amount and with such companies as Landlord shall reasonably approve. In addition, Tenant shall cause each contractor to carry insurance in accordance with Section 13.14 hereof and to deliver to Landlord certificates of all such insurance. Tenant shall also prepare and submit to Landlord a set of as-built plans, in both print and electronic forms, showing such work performed by Tenant to the Premises promptly after any such alterations, improvements or installations are substantially complete and promptly after any wiring or cabling for Tenant’s computer, telephone and other communications systems is installed by Tenant or Tenant’s contractor. Without limiting any of Tenant’s obligations hereunder, Tenant shall be responsible, as Additional Rent, for the costs of any alterations, additions or improvements in or to the Building that are required in order to comply with Legal Requirements as a result of any work performed by Tenant. Landlord shall have the right to provide rules and regulations relative to the performance of any alterations, additions, improvements and installations by Tenant hereunder and Tenant shall abide by all such reasonable rules and regulations and shall cause all of its contractors to so abide including, without limitation, payment for the costs of using Building services. Tenant acknowledges and agrees that Landlord shall be the owner of any additions, alterations and improvements in the Premises or the Building to the extent paid for by Landlord. 
9.4Liens 
Tenant covenants and agrees to pay promptly when due the entire cost of any work done on the Premises by Tenant, its agents, employees or contractors, and not to cause or permit any liens for labor or materials performed or furnished in connection therewith to attach to the Premises or the Building or the Prudential Center and immediately to discharge any such liens which may so attach.  
9.5Nature of Alterations 
All work, construction, repairs, alterations, other improvements or installations made to or upon the Premises (including, but not limited to, the construction performed by Landlord under Article IV), shall become part of the Premises and shall become the property of Landlord and remain upon and be surrendered with the Premises as a part thereof upon the expiration or earlier termination of the Lease Term, except as follows: 
(a)All trade fixtures whether by law deemed to be a part of the realty or not, installed at any time or times by Tenant or any person claiming under Tenant shall remain the property of Tenant or persons claiming under Tenant and may be removed by Tenant or any person claiming under Tenant at any time or times during the Lease Term or any occupancy by Tenant thereafter and shall be removed by Tenant at the expiration or earlier termination of the Lease Term if so requested by Landlord. Tenant shall repair any damage to the Premises occasioned by the removal by Tenant or any person claiming under Tenant of any such property from the Premises. 
(b)At the expiration or earlier termination of the Lease Term, Tenant shall remove: (i) any wiring, cables or other installations appurtenant thereto for Tenant’s computer, telephone and other communication systems and equipment whether located in the Premises or in any other portion of the Building, including all risers (collectively, “Cable”), unless Landlord notifies Tenant in writing that such Cable shall remain in the Premises, and (ii) any alterations, additions and improvements made with Landlord’s consent during the Lease Term for which such removal was made a condition of such consent under Section 9.1(b). Upon such removal 

Tenant shall restore the Premises to their condition prior to such alterations, additions and improvements and repair any damage occasioned by such removal and restoration. 
(c)If Tenant shall make any alterations, additions or improvements to the Premises for which Landlord’s approval is required under Section 9.1 without obtaining such approval, then at Landlord’s request at any time during the Lease Term, and at any event at the expiration or earlier termination of the Lease Term, Tenant shall remove such alterations, additions and improvements and restore the Premises to their condition prior to same and repair any damage occasioned by such removal and restoration. Nothing herein shall be deemed to be a consent to Tenant to make any such alterations, additions or improvements, the provisions of Section 9.1 being applicable to any such work. 
9.6Increases in Taxes 
Tenant shall pay, as Additional Rent, one hundred percent (100%) of any increase in real estate taxes on the Building which shall, at any time after the Rent Commencement Date, result from alterations, additions or improvements to the Premises made by Tenant if the taxing authority specifically determines such increase results from such alterations, additions or improvements made by Tenant. 
ARTICLE X 
Parking
10.1Parking Privileges 
Landlord shall provide to Tenant monthly parking privileges in the Prudential Center Garage (the “Garage”) for four (4) passenger automobiles for the parking of motor vehicles in unreserved stalls in the Garage by Tenant’s employees commencing on the Commencement Date. In the event that the Rentable Floor Area of the Premises decreases at any time during the Lease Term, the number of parking privileges provided to Tenant hereunder shall be reduced proportionately.  
10.2Parking Charges 
Tenant shall pay for such parking privileges at the prevailing monthly rates from time to time charged by the operator or operators of the Garage, whether or not such operator is an affiliate of Landlord. Such monthly parking charges for parking privileges shall constitute Additional Rent and shall be payable monthly as directed by Landlord upon billing therefor by Landlord or such operator. Tenant acknowledges that said monthly charges to be paid under this Section are for the use by the Tenant of the parking privileges referred to herein, and not for any other service. 
10.3Garage Operation 
Unless otherwise determined by Landlord or the operator of such garage (the “Garage Operator”), the Garage is to be operated on a self-parking basis, and Tenant shall be obligated to park and remove its own automobiles, and Tenant’s parking shall be on an unreserved basis, Tenant having the right to park in any available stalls. Tenant’s access and use privileges with respect to the Garage shall be in accordance with regulations of uniform applicability to the users of the Garage from time to time established by the Landlord or the Garage Operator. Tenant shall receive one (1) identification sticker or pass and one (1) magnetic card so-called, or other suitable device providing access to the Garage, for each parking privilege paid for by Tenant. Tenant shall supply Landlord with an identification roster listing, for each identification sticker or pass, the name of the employee and the make, color and registration number of the vehicle to which it has been assigned, and shall provide a revised roster to Landlord monthly indicating changes thereto. Any automobile found parked in the Garage during normal business hours without appropriate identification will be subject to being towed at said automobile owner’s expense. The parking privileges granted herein are non-transferable (other than to a permitted assignee or subtenant pursuant to the applicable provisions of Article XII hereof). Landlord or the Garage Operator may 

institute a so-called valet parking program for the Garage, and in such event Tenant shall cooperate in all respects with such program. Landlord reserves for itself and any other PruOwner the right to alter the Garage as it sees fit and in such case to change the Garage including the reduction in area of the same, Tenant acknowledging that in connection with the potential expansion of buildings in the Prudential Center or the addition of other buildings thereto, it may be necessary to make significant changes to the Garage which may result in the reduction of the amount of parking available in the Garage and the change of location of such parking or may change the access to or egress from the Garage, all of which Landlord or any other PruOwner may perform in its sole and exclusive discretion, without limitation to its other rights in respect thereof.
10.4Limitations 
Tenant agrees that it and all persons claiming by, through and under it, shall at all times abide by all reasonable rules and regulations promulgated by Landlord or the Garage Operator with respect to the use of the Garage. Except to the extent of gross negligence or willful acts, neither the Landlord nor the Garage Operator assumes any responsibility whatsoever for loss or damage due to fire or theft or otherwise to any automobile or to any personal property therein, however caused, and Tenant agrees, upon request from the Landlord, from time to time, to notify its officers, employees and agents then using any of the parking privileges provided for herein, of such limitation of liability. Tenant further acknowledges and agrees that a license only is hereby granted, and no bailment is intended or shall be created.

In the event Tenant pays any utilities for the Premises directly to the utility company or provider, Tenant shall grant Landlord access to Tenant’s account with such utility company or provider so that Landlord can review the utility bills relating to the Premises.

Further, (i) Tenant shall not, nor shall Tenant permit its employees, invitees, agents, independent contractors, contractors, assignees or subtenants to, keep, maintain, store or dispose of (into the sewage or waste disposal system or otherwise) or engage in any activity which might produce or generate any substance which is or may hereafter be classified as a hazardous material, waste or substance (collectively “Hazardous Materials”), under federal, state or local laws, rules and regulations, including, without limitation, 42 U.S.C. Section 6901 et seq., 42 U.S.C. Section 9601 et seq., 42 U.S.C. Section 2601 et seq., 49 U.S.C.

customer handbook currently in existence or hereafter implemented, of which Tenant has been given notice, for the care and use of the Building and the Prudential Center and their facilities and approaches, but Landlord shall not be liable to Tenant for the failure of other occupants of the Building to conform to such rules and regulations. If and to the extent there is any conflict between the provisions of this Lease and any rules and regulations or customer handbook for the Building, the provisions of this Lease shall control. 
11.4To comply with all applicable Legal Requirements now or hereafter in force regarding the operation of Tenant’s business and the use, condition, configuration and occupancy of the Premises, including without limitation, all applicable standards and regulations of the Federal Occupational Safety and Health Administration (“OSHA Requirements”), which obligation shall include ensuring that all contractors (including sub-contractors) that Tenant utilizes to perform work in the Premises comply with OSHA Requirements and that all required training is provided for such work. In addition, Tenant shall, at its sole cost and expense, promptly comply with any Legal Requirements that relate to the Base Building (as hereinafter defined), but only to the extent such obligations are triggered by Tenant’s use of the Premises, other than for general office use, or alterations, additions or improvements in the Premises performed or requested by Tenant. “Base Building” shall include the structural portions of the Building, the public restrooms and the Building mechanical, electrical and plumbing systems and equipment located in the internal core of the Building on the floor or floors on which the Premises are located. Tenant shall promptly pay all fines, penalties and damages that may arise out of or be imposed because of its failure to comply with the provisions of this Section 11.4.

11.6To pay promptly when due all taxes which may be imposed upon personal property (including, without limitation, fixtures and equipment) in the Premises to whomever assessed. 
11.7To pay, as Additional Rent, all reasonable costs, counsel and other fees incurred by Landlord in connection with the successful enforcement by Landlord of any obligations of Tenant under this Lease or in connection with any bankruptcy case involving Tenant or any guarantor. 
11.8To comply with all applicable Legal Requirements now or hereafter in force which shall impose a duty on Landlord or Tenant relating to or as a result of the use or occupancy of the Premises; provided that Tenant shall not be required to make any alterations or additions to the structure, roof, exterior and load bearing walls, foundation, structural floor slabs and other structural elements of the Building unless the same are required by such Legal Requirements as a result of or in connection with Tenant’s use or occupancy of the Premises beyond normal use of space of this kind. Tenant shall promptly pay all fines, penalties and damages that may arise out of or be imposed because of its failure to comply with the provisions of this Section 11.8. 
11.9The word “Prudential” alone or in any combination other than “Prudential Center” shall not be used by the Tenant for any purpose whatsoever. Tenant shall not use the words “Prudential Center” other than as part of the business address of Tenant and then only in such manner as will not appear to be part of Tenant’s name. Tenant shall not use the words “Prudential Center” in any manner which is undignified, confusing, detrimental or misleading in Landlord’s opinion and shall give no greater prominence to the words “Prudential Center” than to any other part of the business address of Tenant and shall give less prominence to the words “Prudential Center” than to Tenant’s name. The Tenant shall not utilize signage or advertising which contains (a) any description of the Prudential Center or the description of the location of the Premises other than “Prudential Center,” “at Prudential Center,” or an official street address such as “Boylston Street” or “Huntington Avenue” or a regional locator such as “Boston” or “Back Bay” and (b) any name of a building, space or area within the Prudential Center other than “Prudential Tower” if Tenant is located within the Prudential Tower in order to describe the location of the Premises. 
In order to reduce peak-hour trip generation of employees at the Prudential Center, the Landlord encourages all employers at the Prudential Center to adopt flexible work schedules for its employees. The Landlord encourages all employers at the Prudential Center to participate in the Corporate Pass Program of the Massachusetts Bay Transit Authority which is designed to encourage the use of mass transit by persons working in Boston. As of June 1988, one hundred and twenty-five greater Boston companies provided subsidies for the purchase by their employees of monthly transit passes through this program with subsidies ranging from 10% to 100% of the cost of the transit pass. The provision of transit pass subsidies may also offer certain benefits to employers under tax law. The Landlord encourages all employers at the Prudential Center to participate in this program and to inform their employees of the benefits of using monthly transit passes. 

11.10Any vendors engaged by Tenant to perform services in or to the Premises including, without limitation, janitorial contractors and moving contractors shall be coordinated with any work being performed by or for Landlord and in such manner as to maintain harmonious labor relations and not to damage the Building or Prudential Center or interfere with Building construction or operation and shall be performed by vendors first approved by Landlord. 
11.11As an inducement to Landlord to enter into this Lease, Tenant hereby represents and warrants that: (i) Tenant is not, nor is fifty percent (50%) or more of Tenant owned or controlled directly or indirectly by, any person, group, entity or nation named on the Specially Designated Nationals and Blocked Persons List maintained by the Office of Foreign Assets Control of the United States Treasury (“OFAC”) (any such person, group, entity or nation being hereinafter referred to as a “Prohibited Person”); (ii) Tenant is not (nor is fifty percent (50%) or more of Tenant owned, controlled, directly or indirectly, by any person, group, entity or nation which is) acting directly or indirectly for or on behalf of any Prohibited Person; and (iii) Tenant (and any person, group, or entity which Tenant controls, directly or indirectly) has not conducted nor will conduct business nor has engaged nor will engage in any transaction or dealing with any Prohibited Person that either may cause or causes Landlord to be in violation of any OFAC rule or regulation, including without limitation any assignment of this Lease or any subletting of all or any portion of the Premises. In connection with the foregoing, it is expressly understood and agreed that (x) any breach by Tenant of the representations and warranties in this Section 11.11 shall be deemed an immediate Event of Default by Tenant under Section 15.1(d) of this Lease (without the benefit of notice or grace) and shall be covered by the indemnity provisions of Section 13.1 below, and (y) the representations and warranties contained in this subsection shall be continuing in nature and shall survive the expiration or earlier termination of this Lease. 
ARTICLE XII 
Assignment and Subletting 
12.1Restrictions on Transfer
Except as otherwise expressly provided herein, Tenant covenants and agrees that it shall not assign, mortgage, pledge, hypothecate or otherwise transfer this Lease and/or Tenant’s interest in this Lease or sublet (which term, without limitation, shall include granting of concessions, licenses or the like) the whole or any part of the Premises. If and so long as Tenant is a corporation with fewer than five hundred (500) shareholders or a limited liability company or a partnership, an assignment, within the meaning of this Article XII, shall be deemed to include one or more sales or transfers of stock or membership or partnership interests, by operation of law or otherwise, or the issuance of new stock or membership or partnership interests, by which an aggregate of more than fifty percent (50%) of Tenant’s stock or membership or partnership interests shall be vested in a party or parties who are not stockholders or members or partners as of the date hereof (a “Majority Interest Transfer”). For the purpose of this Section 12.1, ownership of stock or membership or partnership interests shall be determined in accordance with the principles set forth in Section 544 of the Internal Revenue Code of 1986, as amended from time to time, or the corresponding provisions of any subsequent law. In addition, the following shall be deemed an assignment within the meaning of this Article XII: (a) the merger or consolidation of Tenant into or with any other entity, or the sale of all or substantially all of its assets, and (b) the establishment by the Tenant or a permitted successor or assign of one or more series of (1) members, managers, limited liability company interests or assets, which may have separate rights, powers or duties with respect to specified property or obligations of the Tenant (or such successor or assignee) or profits or losses associated with specified property or obligations of the Tenant (or such successor or assignee), pursuant to §18-215 of the Delaware Limited Liability Company Act, as amended, or similar laws of other states or otherwise, or (2) limited partners, general partners, partnership interests or assets, which may have separate rights, powers or duties with respect to specified property or obligations of the Tenant (or such successor or assignee) or profits or losses associated with specified property or obligations of the Tenant (or such successor or assignee) pursuant to §17-218 of the Delaware Revised Uniform Limited Partnership Act, as amended, or similar laws of other states or otherwise (a “Series Reorganization”). Any assignment, mortgage, pledge, hypothecation, transfer or subletting not expressly permitted in or consented to by Landlord under this Article XII shall, at Landlord’s election, be void; shall be of no force and effect; and shall confer no rights on or in favor of third parties. In addition, Landlord shall be entitled to seek specific performance of or other equitable relief with respect to the provisions hereof. The limitations of this Section 12.1 shall be deemed to apply to any guarantor(s) of this Lease. 
12.2Tenant’s Notice 
Notwithstanding the provisions of Section 12.1 above, in the event Tenant desires to assign this Lease or to sublet the whole (but not part) of the Premises (no partial subletting being permitted other than as provided in 

Section 12.5 below), Tenant shall give Landlord notice (the “Proposed Transfer Notice”) of any proposed sublease or assignment, and said notice shall specify the provisions of the proposed assignment or subletting, including (a) the name and address of the proposed assignee or subtenant, (b) in the case of a proposed assignment or subletting pursuant to Section 12.4 below, such information as to the proposed assignee’s or proposed subtenant’s net worth and financial capability and standing as may reasonably be required for Landlord to make the determination referred to in said Section 12.4 (provided, however, that Landlord shall hold such information confidential having the right to release same to its officers, accountants, attorneys and mortgage lenders on a confidential basis), (c) all of the terms and provisions upon which the proposed assignment or subletting is to be made, (d) in the case of a proposed assignment or subletting pursuant to Section 12.4 below, all other information necessary to make the determination referred to in said Section 12.4 and (e) in the case of a proposed assignment or subletting pursuant to Section 12.5 below, such information as may be reasonably required by Landlord to determine that such proposed assignment or subletting complies with the requirements of said Section 12.5.  
12.3Landlord’s Termination Right 
Landlord shall have the right at its sole option, to be exercised within thirty (30) days after receipt of Tenant’s Proposed Transfer Notice (the “Acceptance Period”), to terminate this Lease as of a date specified in a notice to Tenant, which date shall not be earlier than sixty (60) days nor later than one hundred and twenty (120) days after Landlord’s notice to Tenant; provided, however, that upon the termination date as set forth in Landlord’s notice, all obligations relating to the period after such termination date (but not those relating to the period before such termination date) shall cease and promptly upon being billed therefor by Landlord, Tenant shall make final payment of all Annual Fixed Rent and Additional Rent due from Tenant through the termination date. In the event that Landlord shall not exercise its termination rights as aforesaid, or shall fail to give any or timely notice pursuant to this Section the provisions of Sections 12.4, 12.6 and 12.7 shall be applicable. If Landlord exercises its termination right, then Landlord shall be free to lease the Premises or applicable portion thereof, to any person or persons, including, without limitation, to Tenant’s prospective assignee or subtenant.  This Section 12.3 shall not be applicable to an assignment or sublease pursuant to Section 12.5. 
12.4Consent of Landlord 
Notwithstanding the provisions of Section 12.1 above, but subject to the provisions of this Section 12.4 and the provisions of Sections 12.6 and 12.7 below, in the event that Landlord shall not have exercised the termination right as set forth in Section 12.3, or shall have failed to give any or timely notice under Section 12.3, then for a period of ninety (90) days (i) after the receipt of Landlord’s notice stating that Landlord does not elect the termination right, or (ii) after the expiration of the Acceptance Period, in the event Landlord shall not give any or timely notice under Section 12.3 as the case may be, Tenant shall have the right to assign this Lease or sublet the whole (but not part) of the Premises in accordance with the Proposed Transfer Notice provided that, in each instance, Tenant first obtains the express prior written consent of Landlord, which consent shall not be unreasonably withheld or delayed.  
Without limiting the foregoing standard, Landlord shall not be deemed to be unreasonably withholding its consent to such a proposed assignment or subleasing if: 
(a)the proposed assignee or subtenant is an occupant of the Building or elsewhere in the Prudential Center or is (or within the previous sixty (60) days has been) in active negotiation with Landlord or an affiliate of Landlord for premises in the Building or elsewhere in the Prudential Center or is not of a character consistent with the operation of a first class office building (by way of example Landlord shall not be deemed to be unreasonably withholding its consent to an assignment or subleasing to any governmental or quasi-governmental agency), or 
(b)the proposed assignee or subtenant is not of good character and reputation, or 
(c)the proposed assignee or subtenant does not possess adequate financial capability to perform the Tenant obligations as and when due or required, or 
(d)the assignee or subtenant proposes to use the Premises (or part thereof) for a purpose other than the purpose for which the Premises may be used as stated in Section 1.1 hereof, or 

(e)the character of the business to be conducted or the proposed use of the Premises by the proposed subtenant or assignee shall (i) be likely to increase Operating Expenses for the Building beyond that which Landlord now incurs for use by Tenant; (ii) be likely to increase the burden on elevators or other Building systems or equipment over the burden generated by normal and customary office usage; or (iii) violate or be likely to violate any provisions or restrictions contained herein relating to the use or occupancy of the Premises, or 
(f)there shall be existing an Event of Default (defined in Section 15.1) or there have been three (3) or more Event of Default occurrences during the Lease Term, or 
(g)the proposed rent and other charges to be payable by the proposed assignee or subtenant are less than the market rent and other charges for first class office space for properties of a similar character in the Boston Downtown market, or 
(h)any part of the rent payable under the proposed assignment or sublease shall be based in whole or in part on the income or profits derived from the Premises or if any proposed assignment or sublease shall potentially have any adverse effect on the real estate investment trust qualification requirements applicable to Landlord and its affiliates, or 
(i)the holder of any mortgage or ground lease on property which includes the Premises does not approve of the proposed assignment or sublease, or 
(j)due to the identity or business of a proposed assignee or subtenant, such approval would cause Landlord to be in violation of any covenant or restriction contained in another lease or other agreement affecting space in the Building or elsewhere in the Prudential Center. 
If Landlord shall consent to the proposed assignment or subletting, as the case may be, then, in such event, Tenant may thereafter sublease (the whole but not part of the Premises) or assign pursuant to Tenant’s notice, as given hereunder; provided, however, that if such assignment or sublease shall not be executed and delivered to Landlord within ninety (90) days after the date of Landlord’s consent, the consent shall be deemed null and void and the provisions of Section 12.2 shall be applicable. 
12.5Exceptions 
Notwithstanding the provisions of Sections 12.1, 12.3 and 12.4 above, but subject to the provisions of Section 12.2 above and Section 12.7 below, Tenant shall have the right: 
(x)to assign this Lease or to sublet the Premises (in whole or in part) to any other entity (the “Successor Entity”) (i) which controls or is controlled by Tenant or Tenant’s parent corporation or which is under common control with Tenant, provided that such transfer or transaction is for a legitimate regular business purpose of Tenant other than a transfer of Tenant’s interest in this Lease, or (ii) which purchases all or substantially all of the assets of Tenant, or (iii) which purchases all or substantially all of the stock of (or other ownership or membership interests in) Tenant or (iv) which merges or combines with Tenant, or 
(y)to effect a Series Reorganization, or
(z)to engage in a Majority Interest Transfer,  
provided that in any of the foregoing events as described in clauses (y) or (z) above the transaction is for a legitimate business purpose of Tenant other than the limitation or segregation of the liabilities of Tenant, and provided further that in any of the foregoing events as described in clauses (x), (y) and (z), the entity to which this Lease is so assigned or which so sublets the Premises or the series established by the Series Reorganization has a credit worthiness (e.g. net assets on a pro forma basis using generally accepted accounting principles consistently applied and using the most recent financial statements) which is the same or better than the Tenant as of the date of this Lease (the foregoing transferees referred to, individually or collectively, as a “Permitted 

Transferee”).  Except in cases of statutory merger or a Series Reorganization, in which case the surviving entity in the merger or the series to which this Lease has been designated shall be liable as the Tenant under this Lease, Tenant shall continue to remain fully liable under this Lease, on a joint and several basis with the Permitted Transferee. If any parent, affiliate or subsidiary of Tenant to which this Lease is assigned or the Premises sublet (in whole or in part) shall cease to be such a parent, affiliate or subsidiary, such cessation shall be considered an assignment or subletting requiring Landlord’s consent. 
12.6Profit on Subleasing or Assignment 
In the case of any assignment or subleasing as to which Landlord may consent (other than an assignment or subletting permitted under Section 12.5 above) such consent shall be upon the express and further condition, covenant and agreement, and Tenant hereby covenants and agrees that, in addition to the Annual Fixed Rent, Additional Rent and other charges to be paid pursuant to this Lease, fifty percent (50%) of the “Assignment/Sublease Profits” (hereinafter defined), if any, shall be paid to Landlord. The “Assignment/Sublease Profits” shall be the excess, if any, of (a) the “Assignment/Sublease Net Revenues” as hereinafter defined over (b) the Annual Fixed Rent and Additional Rent and other charges provided in this Lease (provided, however, that for the purpose of calculating the Assignment/Sublease Profits in the case of a sublease, appropriate proportions in the applicable Annual Fixed Rent, Additional Rent and other charges under this Lease shall be made based on the percentage of the Premises subleased and on the terms of the sublease). The “Assignment/Sublease Net Revenues” shall be the fixed rent, additional rent and all other charges and sums payable either initially or over the term of the sublease or assignment plus all other profits and increases to be derived by Tenant as a result of such subletting or assignment, less the reasonable costs of Tenant incurred in such subleasing or assignment (the definition of which shall be limited to brokerage commissions and alteration allowances, in each case actually paid), as set forth in a statement certified by an appropriate officer of Tenant and delivered to Landlord within thirty (30) days of the full execution of the sublease or assignment document, amortized over the term of the sublease or assignment. 
All payments of the Assignment/Sublease Profits due Landlord shall be made within ten (10) days of receipt of same by Tenant. 
12.7Additional Conditions 
(A)It shall be a condition of the validity of any assignment or subletting consented to under Section 12.4 above, or any assignment or subletting of right under Section 12.5 above, that both Tenant and the assignee or sublessee enter into a separate written instrument directly with Landlord in a form and containing terms and provisions reasonably required by Landlord, including, without limitation, the agreement of the assignee or sublessee to be bound directly to Landlord for all the obligations of the Tenant under this Lease (including any amendments or extensions thereof), including, without limitation, the obligation (a) to pay the rent and other amounts provided for under this Lease (but in the case of a partial subletting pursuant to Section 12.5, such subtenant shall agree on a pro rata basis to be so bound) and (b) to comply with the provisions of Article XII hereof and (c) to indemnify the “Landlord Parties” (as defined in Section 13.13) as provided in Section 13.1 hereof. Such assignment or subletting shall not relieve the Tenant named herein of any of the obligations of the Tenant hereunder and Tenant shall remain fully and primarily liable therefor and the liability of Tenant and such assignee (or subtenant, as the case may be) shall be joint and several. Further, and notwithstanding the foregoing, the provisions hereof shall not constitute a recognition of the sublease or the subtenant thereunder, as the case may be, and at Landlord’s option, upon the termination or expiration of the Lease (whether such termination is based upon a cause beyond Tenant’s control, a default of Tenant, the agreement of Tenant and Landlord or any other reason), the sublease shall be terminated. 
(B)As Additional Rent, Tenant shall pay to Landlord as a fee for Landlord’s review of any proposed assignment or sublease requested by Tenant and the preparation of any associated documentation in connection therewith, within thirty (30) days after receipt of an invoice from Landlord, an amount equal to the sum of (i) $1,000.00 and/or (ii) reasonable out of pocket legal fees or other expenses incurred by Landlord in connection with such request.  
(C)If this Lease be assigned, or if the Premises or any part thereof be sublet or occupied by anyone other than Tenant, Landlord may upon prior notice to Tenant, at any time and from time to time, collect rent and other charges from the assignee, sublessee or occupant and apply the net amount collected to the rent and other charges herein reserved, but no such assignment, subletting, occupancy or collection shall be deemed a waiver of this covenant, or a waiver of the provisions of Article XII hereof, or the acceptance of the assignee, sublessee or 

occupant as a tenant or a release of Tenant from the further performance by Tenant of covenants on the part of Tenant herein contained, the Tenant herein named to remain primarily liable under this Lease. 
(D)The consent by Landlord to an assignment or subletting under Section 12.4 above, or the consummation of an assignment or subletting of right under Section 12.5 above, shall in no way be construed to relieve Tenant from obtaining the express consent in writing of Landlord to any further assignment or subletting. 
(E)On or after the occurrence of an “Event of Default” (defined in Section 15.1), Landlord shall be entitled to one hundred percent (100%) of any Assignment/Sublease Profits. 
(F)Without limiting Tenant’s obligations under Article IX, Tenant shall be responsible, at Tenant’s sole cost and expense, for performing all work necessary to comply with Legal Requirements and Insurance Requirements in connection with any assignment or subletting hereunder including, without limitation, any work in connection with such assignment or subletting. 
ARTICLE XIII 
Indemnity and Insurance 
13.1Tenant’s Indemnity 
(a)Indemnity. To the fullest extent permitted by law, Tenant waives any right to contribution against the Landlord Parties (as hereinafter defined) and agrees to indemnify and save harmless the Landlord Parties from and against all claims of whatever nature by a third party arising from or claimed to have arisen from (i) any act, omission or negligence of the Tenant Parties (as hereinafter defined); (ii) any accident, injury or damage whatsoever caused to any person, or to the property of any person, occurring in or about the Premises from the earlier of (A) the date on which any Tenant Party first enters the Premises for any reason or (B) the Commencement Date, and thereafter throughout and until the end of the Lease Term, and after the end of the Lease Term for so long after the end of the Lease Term as any of Tenant’s Property (as defined in Section 13.4) remains on the Premises, or Tenant or anyone acting by, through or under Tenant may use, be in occupancy of any part of, or have access to the Premises or any portion thereof;  (iii) any accident, injury or damage whatsoever occurring outside the Premises but within the Building or the Garage, or on common areas or the Prudential Center, where such accident, injury or damage results, or is claimed to have resulted, from any act, omission or negligence on the part of any of the Tenant Parties; or (iv) any breach of this Lease by Tenant. Tenant shall pay such indemnified amounts as they are incurred by the Landlord Parties. This indemnification shall not be construed to deny or reduce any other rights or obligations of indemnity that any of the Landlord Parties may have under this Lease. The indemnification rights of Landlord Parties provided in this Lease are their exclusive indemnification rights with respect to this Lease.  Landlord Parties waive any additional rights to indemnification they may have against Tenant Parties with respect to this Lease under common law.  Notwithstanding anything contained herein to the contrary, Tenant shall not be obligated to indemnify a Landlord Party for any claims to the extent that such Landlord Party’s damages in fact result from matters included in Landlord’s indemnity in Section 13.1.1 of this Article.   
(b)Breach. In the event that either party hereto breaches any of its indemnity obligations hereunder: (i) such party shall pay to the other party all liabilities, loss, cost, or expense (including reasonable attorneys’ fees) incurred as a result of said breach, and the reasonable value of time expended by the other party as a result of said breach; and (ii) the Landlord Parties may deduct and offset from any amounts due to Tenant under this Lease any amounts owed by Tenant pursuant to this Section 13.1(b). 
(c)No limitation. The indemnification obligations under this Section 13.1 shall not be limited in any way by any limitation on the amount or type of damages, compensation or benefits payable by or for Tenant or any subtenant or other occupant of the Premises under workers’ compensation acts, disability benefit acts, or other employee benefit acts. Tenant waives any immunity from or limitation on its indemnity or contribution liability to the Landlord Parties based upon such acts. 
(d)Subtenants and other occupants. Tenant shall require its subtenants and other occupants of the Premises to provide similar indemnities to the Landlord Parties in a form reasonably acceptable to Landlord. 

(e)Survival. The terms of this Section 13.1 shall survive any termination or expiration of this Lease. 
(f)Costs. The foregoing indemnity and hold harmless agreement shall include indemnity for all costs, expenses and liabilities (including, without limitation, attorneys’ fees and disbursements) incurred by the Landlord Parties in connection with any such claim or any action or proceeding brought thereon, and the defense thereof. In addition, in the event that any action or proceeding shall be brought against one or more Landlord Parties by reason of any such claim, Tenant, upon request from the Landlord Party, shall resist and defend such action or proceeding on behalf of the Landlord Party by counsel appointed by Tenant’s insurer (if such claim is covered by insurance without reservation) or otherwise by counsel reasonably satisfactory to the Landlord Party. The Landlord Parties shall not be bound by any compromise or settlement of any such claim, action or proceeding without the prior written consent of such Landlord Parties. 
(g)Landlord Parties and Tenant Parties. The term “Landlord Party” or “Landlord Parties” shall mean Landlord, any affiliate of Landlord, Landlord’s managing agents for the Building, each mortgagee (if any), each ground lessor (if any), and each of their respective direct or indirect partners, officers, shareholders, directors, members, trustees, beneficiaries, servants, employees, principals, contractors, licensees, agents or representatives. For the purposes of this Lease, the term “Tenant Party” or “Tenant Parties” shall mean Tenant, any affiliate of Tenant, any permitted subtenant or any other permitted occupant of the Premises, and each of their respective direct or indirect partners, officers, shareholders, directors, members, trustees, beneficiaries, servants, employees, principals, contractors, licensees, agents, invitees or representatives. 
13.1.113.1.1 Landlord’s Indemnity.  Subject to the limitations in Section 16.24 and in Section 13.2 and Section 13.13 of this Article, and to the extent not resulting from any act, omission, fault, negligence or misconduct of Tenant or its contractors, licensees, invitees, agents, servants or employees, Landlord waives its right to contribution and agrees to indemnify and save harmless Tenant from and against any claim by a third party arising from (i) any injury to any person occurring in the Premises or in the Complex after the date that possession of the Premises is first delivered to Tenant and until the expiration or earlier termination of the Lease Term, to the extent such injury results from the negligence or willful misconduct of Landlord or Landlord's employees, or from any breach or default by Landlord in the performance or observance of its covenants or obligations under this Lease; or (ii) any breach of this Lease by Landlord; provided, however, that in no event shall the aforesaid indemnity render Landlord responsible or liable for any loss or damage to fixtures, personal property or other property of Tenant, and Landlord shall in no event be liable for any indirect or consequential damages.  Tenant shall provide notice of any such third party claim to Landlord as soon as practicable. Landlord shall have the right, but not the duty, to defend the claim.  The provisions of this Section shall not be applicable to (i) the holder of any mortgage now or hereafter on the Property or Building (whether or not such holder shall be a mortgagee in possession of or shall have exercised any rights under a conditional, collateral or other assignment of leases and/or rents respecting the Property or Building), or (ii) any person acquiring title as a result of, or subsequent to, a foreclosure of any such mortgage or a deed in lieu of foreclosure, except to the extent of liability insurance maintained by either of the foregoing.  The indemnification rights of Tenant provided in this Lease are its exclusive indemnification rights with respect to this Lease.  Tenant waives any additional rights to indemnification it may have against Landlord Parties with respect to this Lease under common law. 
13.2Tenant’s Risk 
Tenant agrees to use and occupy the Premises, and to use such other portions of the Building and the Prudential Center as Tenant is given the right to use by this Lease at Tenant’s own risk. The Landlord Parties shall not be liable to the Tenant Parties for any damage, injury, loss, compensation, or claim (including, but not limited to, claims for the interruption of or loss to a Tenant Party’s business) based on, arising out of or resulting from any cause whatsoever, including, but not limited to, repairs to any portion of the Premises or the Building or the Prudential Center, any fire, robbery, theft, mysterious disappearance, or any other crime or casualty, the actions of any other tenants of the Building or of any other person or persons, or any leakage in any part or portion of the Premises or the Building or the Prudential Center, or from water, rain or snow that may leak into, or flow from any part of the Premises or the Building or the Prudential Center, or from drains, pipes or plumbing fixtures in 

the Building or the Prudential Center. Any goods, property or personal effects stored or placed in or about the Premises shall be at the sole risk of the Tenant Party, and neither the Landlord Parties nor their insurers shall in any manner be held responsible therefor. The Landlord Parties shall not be responsible or liable to a Tenant Party, or to those claiming by, through or under a Tenant Party, for any loss or damage that may be occasioned by or through the acts or omissions of persons occupying adjoining premises or any part of the premises adjacent to or connecting with the Premises or any part of the Building or otherwise. The provisions of this section shall be applicable to the fullest extent permitted by law, and until the expiration or earlier termination of the Lease Term, and during such further period as any of Tenant’s Property remains on the Premises, or Tenant or anyone acting by, through or under Tenant may use, be in occupancy of any part of, or have access to the Premises or of the Building. 
13.3Tenant’s Commercial General Liability Insurance 
Tenant agrees to maintain in full force on or before the earlier of (i) the date on which any Tenant Party first enters the Premises for any reason or (ii) the Commencement Date, and thereafter throughout and until the end of the Lease Term, and after the end of the Lease Term for so long as any of Tenant’s Property remains on the Premises, or Tenant or anyone acting by, through or under Tenant may use, be in occupancy of any part of, or have access to the Premises or any portion thereafter, a policy of commercial general liability insurance, on an occurrence basis, issued on a form at least as broad as Insurance Services Office (“ISO”) Commercial General Liability Coverage “occurrence” form CG 00 01 10 01 or another Commercial General Liability “occurrence” form providing equivalent coverage. Such insurance shall include contractual liability coverage, specifically covering but not limited to the indemnification obligations undertaken by Tenant in this Lease. The minimum limits of liability of such insurance shall be Three Million Dollars ($3,000,000) per occurrence, which may be satisfied through a combination of primary and excess/umbrella insurance. In addition, in the event Tenant hosts a function in the Premises, in the Building or on the Property, Tenant agrees to obtain, and cause any persons or parties providing services for such function to obtain, the appropriate insurance coverages as determined by Landlord (including liquor liability coverage, if applicable) and provide Landlord with evidence of the same.  
13.4Tenant’s Property Insurance 
Tenant shall maintain at all times during the Lease Term, and during such earlier or later time as Tenant may be performing work in or to the Premises or have property, fixtures, furniture, equipment, machinery, goods, supplies, wares or merchandise on the Premises, and continuing thereafter so long as any of Tenant’s Property, remains on the Premises, or Tenant or anyone acting by, through or under Tenant may use, be in occupancy of or have access to, any part of the Premises, business interruption insurance and insurance against loss or damage covered by the so-called “all risk” or equivalent type insurance coverage with respect to (i) Tenant’s property, fixtures, furniture, equipment, machinery, goods, supplies, wares and merchandise, and other property of Tenant located at the Premises, (ii) all additions, alterations and improvements made by or on behalf of the Tenant in the Premises (except to the extent paid for by Landlord in connection with this Lease) or existing in the Premises as of the date of this Lease (“Leasehold Improvements”), and (iii) any property of third parties, including but not limited to leased or rented property, in the Premises in Tenant’s care, custody, use or control, provided that such insurance in the case of (iii) may be maintained by such third parties, (collectively, “Tenant’s Property”).  At the request of Landlord, Tenant shall provide to Landlord a detailed description of the Leasehold Improvements made by or on behalf of Tenant and the cost thereof. The business interruption insurance required by this section shall be in minimum amounts typically carried by prudent tenants engaged in similar operations, but in no event shall be in an amount less than the Annual Fixed Rent then in effect during any Lease Year, plus any Additional Rent due and payable for the immediately preceding Lease Year.  The “all risk” insurance required by this section shall be in an amount at least equal to the full replacement cost of Tenant’s Property.  In addition, during such time as Tenant is performing work in or to the Premises, Tenant, at Tenant’s expense, shall also maintain, or shall cause its contractor(s) to maintain, builder’s risk insurance for the full insurable value of such work.  Landlord and such additional persons or entities as Landlord may reasonably request shall be named as loss payees, as their interests may appear, on the policy or policies required by this section for Leasehold Improvements. In the event of loss or damage covered by the “all risk” insurance required by this Lease, the responsibilities for repairing or restoring the loss or damage shall be determined in accordance with Article XIV. To the extent that Landlord is obligated to pay for the repair or restoration of the loss or damage covered by the policy, Landlord shall be paid the proceeds of the “all risk” insurance covering the loss or damage. To the extent Tenant is obligated to pay for the repair or restoration of the loss or damage, covered by the policy, Tenant shall be paid the proceeds of the “all risk” insurance covering the loss or damage. If both Landlord and Tenant are obligated to pay for the repair or restoration of the loss or damage covered by the policy, the insurance proceeds shall be paid to each of them in the pro rata proportion of their obligations to repair or restore the loss or damage. If the loss or damage is not repaired or restored (for example, if the Lease is terminated pursuant to Article XIV), 

the insurance proceeds shall be paid to Landlord and Tenant in the pro rata proportion of their relative contributions to the cost of the leasehold improvements covered by the policy.  
13.5Tenant’s Other Insurance 
Tenant agrees to maintain in full force on or before the earlier of (i) the date on which any Tenant Party first enters the Premises for any reason or (ii) the Commencement Date, and thereafter throughout the end of the Lease Term, and after the end of the Lease Term for so long after the end of the Lease Term any of Tenant’s Property remains on the Premises or as Tenant or anyone acting by, through or under Tenant may use, be in occupancy of, or have access to the Premises or any portion thereafter, (1) automobile liability insurance (covering any automobiles owned or operated by Tenant at the Building); (2) worker’s compensation insurance as required by law; and (3) employer’s liability insurance. Such automobile liability insurance shall be in an amount not less than One Million Dollars ($1,000,000) for each accident. Such employer’s liability insurance shall be in an amount not less than One Million Dollars ($1,000,000) for each accident, One Million Dollars ($1,000,000) disease-policy limit, and One Million Dollars ($1,000,000) disease-each employee.  
13.6Requirements for Tenant’s Insurance  
All insurance required to be maintained by Tenant pursuant to this Lease shall be maintained with responsible companies that are admitted to do business, and are in good standing in the Commonwealth of Massachusetts and that have a rating of at least “A” and are within a financial size category of not less than “Class X” in the most current Best’s Key Rating Guide or such similar rating as may be reasonably selected by Landlord. All such insurance shall: (1) be acceptable in form and content to Landlord; and (2) contain a clause requiring the insurer to provide Landlord thirty (30) days’ prior written notice of cancellation or failure to renew.  All commercial general liability, excess/umbrella liability and automobile liability insurance policies shall be primary and noncontributory. No such policy shall contain any self-insured retention greater than Twenty-Five Thousand Dollars ($25,000.00) for property insurance and TwentyFive Thousand Dollars ($25,000.00) for commercial general liability insurance. Any deductibles and such self-insured retentions shall be deemed to be “insurance” for purposes of the waiver in Section 13.13 below. Landlord reserves the right from time to time to require Tenant to obtain higher minimum amounts of insurance based on such limits as are customarily carried with respect to similar properties in the area in which the Premises are located. The minimum amounts of insurance required by this Lease shall not be reduced by the payment of claims or for any other reason. In the event Tenant shall fail to obtain or maintain any insurance meeting the requirements of this Article, or to deliver such policies or certificates as required by this Article, Landlord may, at its option, on five (5) days’ notice to Tenant, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord within five (5) days after delivery to Tenant of bills therefor. 
13.7Additional Insureds 
To the fullest extent permitted by law, the commercial general liability and auto insurance carried by Tenant pursuant to this Lease, and any additional liability insurance carried by Tenant pursuant to Section 13.5 of this Lease or any other provision of this Lease, shall name Landlord, Landlord’s managing agent, and such other persons as Landlord may reasonably request from time to time as additional insureds with respect to liability arising out of or related to this Lease or the operations of Tenant (collectively “Additional Insureds”). Such insurance shall provide primary coverage without contribution from any other insurance carried by or for the benefit of Landlord, Landlord’s managing agent, or other Additional Insureds. Such insurance shall also waive any right of subrogation against each Additional Insured. For the avoidance of doubt, each primary policy and each excess/umbrella policy through which Tenant satisfies its obligations under this Section 13.7 must provide coverage to the Additional Insureds that is primary and non-contributory. 
13.8Certificates of Insurance 
On or before the earlier of (i) the date on which any Tenant Party first enters the Premises for any reason or (ii) the Commencement Date, Tenant shall furnish Landlord with certificates evidencing the insurance coverage required by this Lease, and renewal certificates shall be furnished to Landlord at least annually thereafter, and at least thirty (30) days prior to the expiration date of each policy for which a certificate was furnished (acceptable forms of such certificates for liability and property insurance, respectively, as of the date hereof, are attached as Exhibit H, however, other forms of certificates may satisfy the requirements of this Section 13.8). Failure by the Tenant to provide the certificates required by this Section 13.8 shall not be deemed to be a waiver of the requirements in this Section 13.8. Upon request by Landlord, a true and complete copy of any insurance policy required by this Lease shall be delivered to Landlord within ten (10) days following Landlord’s request. 
13.9Subtenants and Other Occupants 
Tenant shall require its subtenants and other occupants of the Premises to provide written documentation evidencing the obligation of such subtenant or other occupant to indemnify the Landlord Parties to the same extent that Tenant is required to indemnify the Landlord Parties pursuant to Section 13.1 above, and to maintain 

insurance that meets the requirements of this Article, and otherwise to comply with the requirements of this Article, provided that the terms of this Section 13.9 shall not relieve Tenant of any of its obligations to comply with the requirements of this Article. Tenant shall require all such subtenants and occupants to supply certificates of insurance evidencing that the insurance requirements of this Article have been met and shall forward such certificates to Landlord on or before the earlier of (i) the date on which the subtenant first enters the Premises or (ii) the commencement of the sublease. Tenant shall be responsible for identifying and remedying any deficiencies in such certificates or policy provisions. 
13.10No Violation of Building Policies 
Tenant shall not commit or permit any violation of the policies of fire, boiler, sprinkler, water damage or other insurance covering the Prudential Center and/or the fixtures, equipment and property therein carried by Landlord, or do or permit anything to be done, or keep or permit anything to be kept, in the Premises, which in case of any of the foregoing (i) would result in termination of any such policies, (ii) would adversely affect Landlord’s right of recovery under any of such policies, or (iii) would result in reputable and independent insurance companies refusing to insure the Prudential Center or the property of Landlord in amounts reasonably satisfactory to Landlord. 
13.11Tenant to Pay Premium Increases 
If, because of anything done, caused or permitted to be done, or omitted by Tenant (or its subtenant or other occupants of the Premises), the rates for liability, fire, boiler, sprinkler, water damage or other insurance on the Prudential Center or on the property and equipment of Landlord or any other tenant or subtenant in the Building shall be higher than they otherwise would be, Tenant shall reimburse Landlord and/or the other tenants and subtenants in the Building for the additional insurance premiums thereafter paid by Landlord or by any of the other tenants and subtenants in the Building which shall have been charged because of the aforesaid reasons, such reimbursement to be made from time to time on Landlord’s demand.  
13.12Landlord’s Insurance 
(a)Required insurance. Landlord shall maintain insurance against loss or damage with respect to the Building on an “all risk” or equivalent type insurance form, with customary exceptions, subject to such deductibles and self-insured retentions as Landlord may determine, in an amount equal to at least the replacement value of the Building. Landlord shall also maintain such insurance with respect to any improvements, alterations, and fixtures of Tenant located at the Premises to the extent paid for by Landlord. The cost of such insurance shall be treated as a part of Operating Expenses for the Building. Payment for losses thereunder shall be made solely to Landlord.  
(b)Optional insurance. Landlord may maintain such additional insurance with respect to the Building and the Prudential Center, including, without limitation, earthquake insurance, terrorism insurance, flood insurance, liability insurance and/or rent insurance, as Landlord may in its sole discretion elect. Landlord may also maintain such other insurance as may from time to time be required by the holder of any mortgage on the Building or the Prudential Center. The cost of all such additional insurance shall also be part of the Operating Expenses for the Building.  
(c)Blanket and self-insurance. Any or all of Landlord’s insurance may be provided by blanket coverage maintained by Landlord or any affiliate of Landlord under its insurance program for its portfolio of properties, or by Landlord or any affiliate of Landlord under a program of self-insurance, and in such event Operating Expenses for the Building shall include the portion of the reasonable cost of blanket insurance or self-insurance that is allocated to the Building. 
(d)No obligation. Landlord shall not be obligated to insure, and shall not assume any liability of risk of loss for, Tenant’s Property, including any such property or work of Tenant’s subtenants or occupants. Landlord will also have no obligation to carry insurance against, nor be responsible for, any loss suffered by Tenant, subtenants or other occupants due to interruption of Tenant’s or any subtenant’s or occupant’s business. 
13.13Waiver of Subrogation 
To the fullest extent permitted by law, and notwithstanding any term or provision of this Lease to the contrary, the parties hereto waive and release any and all rights of recovery against the other, and agree not to seek to recover from the other or to make any claim against the other, and in the case of Landlord, against all Tenant Parties, and in the case of Tenant, against all Landlord Parties, for any loss or damage incurred by the waiving/releasing party to the extent such loss or damage is insured under any insurance policy required by this Lease or 

which would have been so insured had the party carried the insurance it was required to carry hereunder. Tenant shall obtain from its subtenants and other occupants of the Premises a similar waiver and release of claims against any or all of Tenant or Landlord. In addition, the parties hereto (and in the case of Tenant, its subtenants and other occupants of the Premises) shall procure an appropriate clause in, or endorsement on, any insurance policy required by this Lease pursuant to which the insurance company waives subrogation. The insurance policies required by this Lease shall contain no provision that would invalidate or restrict the parties’ waiver and release of the rights of recovery in this section. The parties hereto covenant that no insurer shall hold any right of subrogation against the parties hereto by virtue of such insurance policy. 
13.14Tenant’s Work 
During such times as Tenant is performing work or having work or services performed in or to the Premises, Tenant shall require its contractors, and their subcontractors of all tiers, to obtain and maintain commercial general liability, automobile, workers compensation, employer’s liability, builder’s risk, and equipment/property insurance in such amounts and on such terms as are customarily required of such contractors and subcontractors on similar projects. The amounts and terms of all such insurance are subject to Landlord’s written approval, which approval shall not be unreasonably withheld. The commercial general liability and auto insurance carried by Tenant’s contractors and their subcontractors of all tiers pursuant to this Section 13.14 shall name the Additional Insureds as additional insureds with respect to liability arising out of or related to their work or services. Such insurance shall provide primary coverage without contribution from any other insurance carried by or for the benefit of Landlord, Landlord’s managing agent, or other Additional Insureds. Such insurance shall also waive any right of subrogation against each Additional Insured. Tenant shall obtain and submit to Landlord, prior to the earlier of (i) the entry onto the Premises by such contractors or subcontractors or (ii) commencement of the work or services, certificates of insurance evidencing compliance with the requirements of this Section 13.14. 
ARTICLE XIV 
Fire, Casualty and Taking 
14.1Damage Resulting from Casualty 
In case the Building is damaged by fire or casualty, and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within one hundred twenty (120) days from the time that repair work would commence as reasonably determined by Landlord, Landlord may, at its election, terminate this Lease by notice given to Tenant within sixty (60) days after the date of such fire or other casualty, specifying the effective date of termination. The effective date of termination specified by Landlord shall not be less than thirty (30) days nor more than forty-five (45) days after the date of notice of such termination. Unless terminated pursuant to the foregoing provisions, this Lease shall remain in full force and effect following any such damage subject, however, to the following provisions. 
If during the last Lease Year of the Lease Term (as it may have been extended), the Building shall be damaged by fire or casualty and such fire or casualty damage to the Premises cannot reasonably be expected to be repaired or restored within one hundred twenty (120) days from the time that repair or restoration work would commence as reasonably determined by Landlord, then Tenant shall have the right, by giving notice to Landlord not later than thirty (30) days after such damage, to terminate this Lease, whereupon this Lease shall terminate as of the date of such notice with the same force and effect as if such date were the date originally established as the expiration date hereof. 
If the Building or any part thereof is damaged by fire or casualty and this Lease is not so terminated, or Landlord has no right to terminate this Lease, and in either such case the holder of any mortgage which includes the Building as a part of the mortgaged premises or any ground lessor of any ground lease which includes the Building as part of the demised premises allows the net insurance proceeds to be applied to the restoration of the Building, Landlord, promptly after such damage and the determination of the net amount of insurance proceeds available shall use due diligence to restore the Premises and the Building in the event of damage thereto (excluding Tenant’s Property (as defined in Section 13.4 hereof)), except as expressly provided in the immediately following paragraph of this Section 14.1) into proper condition for use and occupation and a just proportion of the Annual Fixed Rent, the Operating Cost Excess and the Tax Excess according to the nature and extent of the injury to the Premises shall be abated from the date of casualty until the Premises shall have been put by Landlord substantially into such condition. Notwithstanding the foregoing, Landlord shall not be obligated to expend for such repairs and restoration any amount in excess of the net insurance proceeds. 

Notwithstanding the foregoing, if Landlord is proceeding with the restoration of the Building and the Premises in accordance with the previous paragraph, Landlord shall also restore any alterations, additions or improvements within the Premises that are part of Tenant’s Property (x) which have previously been approved by Landlord in accordance with the terms and provisions of this Lease or which are existing in the Premises as of the date of this Lease, and (y) with respect to which Tenant has carried “all risk” insurance covering the loss or damage in accordance with Section 13.4 above and pays the proceeds of such insurance (or an amount equivalent thereto) to Landlord within five (5) business days following Landlord’s written request); provided, however, that in no event shall Landlord be required to fund any insufficiency in the insurance proceeds (or equivalent amount) provided by Tenant with respect to such loss or damage (or to fund any of the costs of restoration in the absence of any payment by Tenant). 
Where Landlord is obligated or otherwise elects to effect restoration of the Premises, unless such restoration is completed within one (1) year from the date of the casualty, such period to be subject, however, to extension where the delay in completion of such work is due to Force Majeure, as defined hereinbelow (but in no event beyond eighteen (18) months from the date of the casualty or taking), Tenant, as its sole and exclusive remedy, shall have the right to terminate this Lease at any time after the expiration of such one-year (as extended) period until the restoration is substantially completed, such termination to take effect as of the thirtieth (30th) day after the date of receipt by Landlord of Tenant’s notice, with the same force and effect as if such date were the date originally established as the expiration date hereof unless, within such thirty (30) day period such restoration is substantially completed, in which case Tenant’s notice of termination shall be of no force and effect and this Lease and the Lease Term shall continue in full force and effect. The term “Force Majeure” shall mean any prevention, delay or stoppage due to governmental regulation, strikes, lockouts, acts of God, acts of war, terrorists acts, civil commotions, unusual scarcity of or inability to obtain labor or materials, labor difficulties, fire or other casualty (including the time necessary to repair any damage caused thereby) or other causes reasonably beyond Landlord’s control or attributable to Tenant’s action or inaction. 
14.2Uninsured Casualty 
Notwithstanding anything to the contrary contained in this Lease, if the Building or the Premises shall be substantially damaged by fire or casualty as the result of a risk not covered by the forms of casualty insurance at the time maintained by Landlord and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within thirty (30) days from the time that repair work would commence, Landlord may, at its election, terminate the Lease Term by notice to Tenant given within thirty (30) days after such loss. If Landlord shall give such notice, then this Lease shall terminate as of the date of such notice with the same force and effect as if such date were the date originally established as the expiration date hereof. 
14.3Rights of Termination for Taking 
If the Building, or such portion thereof as to render the balance (if reconstructed to the maximum extent practicable in the circumstances) unsuitable for Tenant’s purposes, shall be taken by condemnation or right of eminent domain, Landlord or Tenant shall have the right to terminate this Lease by notice to the other of its desire to do so, provided that such notice is given not later than thirty (30) days after Tenant has been deprived of possession. If either party shall give such notice, then this Lease shall terminate as of the date of such notice with the same force and effect as if such date were the date originally established as the expiration date hereof. 
Further, if so much of the Building or Prudential Center shall be so taken that continued operation of the Building would be uneconomic, Landlord shall have the right to terminate this Lease by giving notice to Tenant of Landlord’s desire to do so not later than thirty (30) days after Tenant has been deprived of possession of the Premises (or such portion thereof as may be taken). If Landlord shall give such notice, then this Lease shall terminate as of the date of such notice with the same force and effect as if such date were the date originally established as the expiration date hereof.  
Should any part of the Premises be so taken or condemned during the Lease Term hereof, and should this Lease not be terminated in accordance with the foregoing provisions, and the holder of any mortgage which includes the Premises as part of the mortgaged premises or any ground lessor of any ground lease which includes the Premises as part of the demised premises allows the net condemnation proceeds to be applied to the restoration of the Building, Landlord agrees that after the determination of the net amount of condemnation proceeds available to Landlord, Landlord shall use due diligence to put what may remain of the Premises into proper condition for use and occupation as nearly like the condition of the Premises prior to such taking as shall be practicable (excluding Tenant’s Property). Notwithstanding the foregoing, Landlord shall not be obligated to expend for such repair and restoration any amount in excess of the net condemnation proceeds made available to it. 
If the Premises shall be affected by any exercise of the power of eminent domain and neither Landlord nor Tenant shall terminate this Lease as provided above, then the Annual Fixed Rent, the Operating Cost Excess and 

the Tax Excess shall be justly and equitably abated and reduced according to the nature and extent of the loss of use thereof suffered by Tenant; and in case of a taking which permanently reduces the Rentable Floor Area of the Premises, a just proportion of the Annual Fixed Rent, the Operating Cost Excess and the Tax Excess shall be abated for the remainder of the Lease Term. 
14.4Award 
Except as otherwise provided in this Section 14.4, Landlord shall have and hereby reserves and excepts, and Tenant hereby grants and assigns to Landlord, all rights to recover for damages to the Building, the Prudential Center, and the Garage and the leasehold interest hereby created, and compensation accrued or hereafter to accrue by reason of such taking, damage or destruction, as aforesaid, and by way of confirming the foregoing, Tenant hereby grants and assigns, and covenants with Landlord to grant and assign to Landlord, all rights to such damages or compensation. 
However, nothing contained herein shall be construed to prevent Tenant from prosecuting in any such proceedings a claim for its trade fixtures so taken or relocation, moving and other dislocation expenses, provided that such action shall not affect the amount of compensation otherwise recoverable by Landlord from the taking authority. 
ARTICLE XV 
Default 
15.1Tenant’s Default 
This Lease and the Lease Term are subject to the limitation that Tenant shall be in default if, at any time during the Lease Term, any one or more of the following events (herein called an “Event of Default” a “default of Tenant” or similar reference) shall occur and not be cured prior to the expiration of the grace period (if any) herein provided, as follows: 
(a)Tenant shall fail to pay any installment of the Annual Fixed Rent, or any Additional Rent or any other monetary amount due under this Lease on or before the date on which the same becomes due and payable, and such failure continues for five (5) days after notice from Landlord thereof; or 
(b)Landlord having rightfully given the notice specified in (a) above to Tenant twice in any twelve (12) month period, Tenant shall fail thereafter to pay the Annual Fixed Rent, Additional Rent or any other monetary amount due under this Lease on or before the date on which the same becomes due and payable; or 
(c)Tenant shall assign its interest in this Lease or sublet any portion of the Premises in violation of the requirements of Article XII of this Lease; or 
(d)Tenant shall fail to perform or observe some term or condition of this Lease which, because of its character, would immediately jeopardize Landlord’s interest (such as, but without limitation, failure to maintain general liability insurance, or the employment of labor and contractors within the Premises which interfere with Landlord’s work, in violation of Sections 9.3, 11.2 or 11.10 or a failure to observe the requirements of Section 11.2), and such failure continues for three (3) days after notice from Landlord to Tenant thereof; or 
(e)Tenant shall fail to perform or observe any other requirement, term, covenant or condition of this Lease (not hereinabove in this Section 15.1 specifically referred to) on the part of Tenant to be performed or observed and such failure shall continue for thirty (30) days after notice thereof from Landlord to Tenant, or if said default shall reasonably require longer than thirty (30) days to cure, if Tenant shall fail to commence to cure said default within thirty (30) days after notice thereof and/or fail to continuously prosecute the curing of the same to completion with due diligence; or  
(f)The estate hereby created shall be taken on execution or by other process of law; or 
(g)Tenant shall make an assignment or trust mortgage arrangement, so-called, for the benefit of its creditors; or 
(h)Tenant shall judicially be declared bankrupt or insolvent according to law; or 

(i)a receiver, guardian, conservator, trustee in involuntary bankruptcy or other similar officer is appointed to take charge of all or any substantial part of Tenant’s property by a court of competent jurisdiction; or 
(j)any petition shall be filed against Tenant in any court, whether or not pursuant to any statute of the United States or of any State, in any bankruptcy, reorganization, composition, extension, arrangement or insolvency proceeding, and such proceedings shall not be fully and finally dismissed within sixty (60) days after the institution of the same; or 
(k)Tenant shall file any petition in any court, whether or not pursuant to any statute of the United States or any State, in any bankruptcy, reorganization, composition, extension, arrangement or insolvency proceeding; or 
(l)Tenant otherwise abandons or vacates the Premises. 
15.2Termination; Re-Entry 
Upon the happening of any one or more of the aforementioned Events of Default (notwithstanding any waiver of a former breach of covenant or consent in a former instance), Landlord or Landlord’s agents or servants may give to Tenant a notice (hereinafter called “notice of termination”) terminating this Lease on a date specified in such notice of termination (which shall be not less than five (5) days after the date of the mailing of such notice of termination), and this Lease and the Lease Term, as well as any and all of the right, title and interest of the Tenant hereunder, shall wholly cease and expire on the date set forth in such notice of termination (Tenant hereby waiving any rights of redemption) in the same manner and with the same force and effect as if such date were the date originally specified herein for the expiration of the Lease Term, and Tenant shall then quit and surrender the Premises to Landlord. 
In addition or as an alternative to the giving of such notice of termination, Landlord or Landlord’s agents or servants may, by any suitable action or proceeding at law, immediately or at any time thereafter re-enter the Premises and remove therefrom Tenant, its agents, employees, servants, licensees, and any subtenants and other persons, and all or any of its or their property therefrom, and repossess and enjoy the Premises, together with all additions, alterations and improvements thereto; but, in any event under this Section 15.2, Tenant shall remain liable as hereinafter provided. 
The words “re-enter” and “re-entry” as used throughout this Article XV are not restricted to their technical legal meanings. 
15.3Continued Liability; Re-Letting 
(A)If this Lease is terminated or if Landlord shall re-enter the Premises as aforesaid, or in the event of the termination of this Lease, or of re- entry, by or under any proceeding or action or any provision of law by reason of an Event of Default hereunder on the part of Tenant, Tenant covenants and agrees forthwith to pay and be liable for, on the days originally fixed herein for the payment thereof, amounts equal to the several installments of Annual Fixed Rent, all Additional Rent and other charges reserved as they would, under the terms of this Lease, become due if this Lease had not been terminated or if Landlord had not entered or re-entered, as aforesaid, and whether the Premises be relet or remain vacant, in whole or in part, or for a period less than the remainder of the Lease Term, or for the whole thereof, but, in the event the Premises be relet by Landlord, Tenant shall be entitled to a credit in the net amount of rent and other charges received by Landlord in reletting, after deduction of all reasonable expenses incurred in reletting the Premises (including, without limitation, remodeling costs, brokerage fees and the like), and in collecting the rent in connection therewith, in the following manner: 
Amounts received by Landlord after reletting shall first be applied against such Landlord’s expenses, until the same are recovered, and until such recovery, Tenant shall pay, as of each day when a payment would fall due under this Lease, the amount which Tenant is obligated to pay under the terms of this Lease (Tenant’s liability prior to any such reletting and such recovery not in any way to be diminished as a result of the fact that such reletting might be for a rent higher than the rent provided for in this Lease); when and if such expenses have been completely recovered, the amounts received from reletting by Landlord as have not previously been applied shall be credited against Tenant’s obligations as of each day when a payment would fall due under this Lease, and only the net amount thereof shall be payable by Tenant. Further, Tenant shall not be entitled to any credit of any kind for any period after the date when the Lease Term is scheduled to expire according to its terms. 

(B)Landlord agrees to use reasonable efforts to relet the Premises after Tenant vacates the same in the event this Lease is terminated based upon an Event of Default by Tenant hereunder. The marketing of the Premises in a manner similar to the manner in which Landlord markets other premises within Landlord’s control within the Building shall be deemed to have satisfied Landlord’s obligation to use “reasonable efforts” hereunder. In no event shall Landlord be required to (i) solicit or entertain negotiations with any other prospective tenant for the Premises until Landlord obtains full and complete possession of the Premises (including, without limitation, the final and unappealable legal right to relet the Premises free of any claim of Tenant), (ii) relet the Premises before leasing other vacant space in the Building, or (iii) lease the Premises for a rental less than the current fair market rent then prevailing for similar office space in the Building. 
(C)In the alternative, Landlord may elect, by notice given to Tenant at any time after the termination of this Lease under Section 15.2, above, and whether or not Landlord shall have collected any damages as hereinbefore provided in this Article XV, but as final damages and in lieu of all other such damages beyond the date of such notice, to require Tenant to pay such a sum as at the time of such notice represents the amount of the excess, if any, of (a) the discounted present value, at a discount rate of 6%, of the Annual Fixed Rent, Additional Rent and other charges which would have been payable by Tenant under this Lease for the remainder of the Lease Term if the Lease terms had been fully complied with by Tenant, over and above (b) the discounted present value, at a discount rate of 6%, of the Annual Fixed Rent, Additional Rent and other charges that would be received by Landlord if the Premises were re- leased at the time of such notice for the remainder of the Lease Term at the fair market value (including provisions regarding periodic increases in Annual Fixed Rent if such are applicable) prevailing at the time of such notice as reasonably determined by Landlord , plus all expenses which Landlord may have incurred with respect to the collection of such damages.  
For the purposes of this Article, if Landlord elects to require Tenant to pay damages in accordance with this Section 15.3(C), the total rent shall be computed by assuming the Tax Excess under Section 6.2 and the Operating Cost Excess under Section 7.5 to be the same as were payable for the twelve (12) calendar months (or if less than twelve (12) calendar months have been elapsed since the date hereof, the partial year) immediately preceding such termination of re-entry. 
(D)Nothing contained in this Lease shall limit or prejudice the right of Landlord to prove for and obtain in proceedings for bankruptcy or insolvency by reason of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceeds in which, the damages are to be proved, whether or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above. 
15.4Liquidated Damages 
In lieu of any other damages or indemnity and in lieu of the recovery by Landlord of all sums payable under all the foregoing provisions of this Article XV, Landlord may elect to collect from Tenant, by notice to Tenant, given to Tenant at the time of termination and Tenant shall thereupon pay, as liquidated damages, an amount equal to the sum of the Annual Fixed Rent and all Additional Rent payable for the twelve (12) months ended next prior to the such termination plus the amount of Annual Fixed Rent and Additional Rent of any kind accrued and unpaid at the time of such termination plus any and all expenses which the Landlord may have incurred for and with respect to the collection of any of such rent. 
15.5Waiver of Redemption 
Tenant, for itself and any and all persons claiming through or under Tenant, including its creditors, upon the termination of this Lease and of the Lease Term in accordance with the terms hereof, or in the event of entry of judgment for the recovery of the possession of the Premises in any action or proceeding, or if Landlord shall enter the Premises by process of law or otherwise, hereby waives any right of redemption provided or permitted by any statute, law or decision now or hereafter in force, and does hereby waive, surrender and give up all rights or privileges which it or they may or might have under and by reason of any present or future law or decision, to redeem the Premises or for a continuation of this Lease for the Lease Term hereby demised after having been dispossessed or ejected therefrom by process of law, or otherwise.  
15.6Landlord’s Default 
Landlord shall in no event be in default in the performance of any of Landlord’s obligations hereunder unless and until Landlord shall have failed to perform such obligations within thirty (30) days, or such additional time 

as is reasonably required to correct any such default, after notice by Tenant to Landlord properly specifying wherein Landlord has failed to perform any such obligation. 
Tenant shall not assert any right to deduct the cost of repairs or any monetary claim against the Landlord from rent thereafter due and payable, but shall look solely to the Landlord for satisfaction of such claim.  
ARTICLE XVI 
Miscellaneous Provisions 
16.1Waiver 
No waiver by either party hereto of any condition of this Lease, nor any failure by Tenant to deliver any security deposit, letter of credit, pre-paid rent, financial information, guaranty or other item required upon the execution and delivery of this Lease, shall be construed as excusing satisfaction of any such condition or the delivery of any such item by the other party, and the waiving party reserves the right to declare the failure of the other party to satisfy any such condition or deliver any such item an Event of Default under this Lease. 
Further, no waiver at any time of any of the provisions hereof by Landlord or Tenant shall be construed as a waiver of any of the other provisions hereof, and a waiver at any time of any of the provisions hereof shall not be construed as a waiver at any subsequent time of the same provisions. The consent or approval of Landlord or Tenant to or of any action by the other requiring such consent or approval shall not be construed to waive or render unnecessary Landlord’s or Tenant’s consent or approval to or of any subsequent similar act by the other. 
No payment by Tenant, or acceptance by Landlord, of a lesser amount than shall be due from Tenant to Landlord shall be treated otherwise than as a payment on account. The acceptance by Landlord of a check for a lesser amount with an endorsement or statement thereon, or upon any letter accompanying such check, that such lesser amount is payment in full, shall be given no effect, and Landlord may accept such check without prejudice to any other rights or remedies which Landlord may have against Tenant. Further, the acceptance by Landlord of Annual Fixed Rent, Additional Rent or any other charges paid by Tenant under this Lease shall not be or be deemed to be a waiver by Landlord of any default by Tenant, whether or not Landlord knows of such default, except for such defaults as to which such payment relates.  
16.2Cumulative Remedies 
Except as expressly provided in this Lease, the specific remedies to which Landlord and Tenant may resort under the terms of this Lease are cumulative and are not intended to be exclusive of any other remedies or means of redress which they may be lawfully entitled to seek in case of any breach or threatened breach of any provisions of this Lease. In addition to the other remedies provided in this Lease, Landlord shall be entitled to the restraint by injunction of the violation or attempted or threatened violation of any of the covenants, conditions or provisions of this Lease or to seek specific performance of any such covenants, conditions or provisions, provided, however, that the foregoing shall not be construed as a confession of judgment by Tenant. 
16.3Quiet Enjoyment 
This Lease is subject and subordinate to all matters of record. Landlord agrees that, upon Tenant’s paying the Annual Fixed Rent, Additional Rent and other charges herein reserved, and performing and observing the covenants, conditions and agreements hereof upon the part of Tenant to be performed and observed, Tenant shall and may peaceably hold and enjoy the Premises during the Lease Term (exclusive of any period during which Tenant is holding over after the expiration or termination of this Lease without the consent of Landlord), without interruption or disturbance from Landlord or persons claiming through or under Landlord, subject, however, to the terms of this Lease. This covenant shall be construed as running with the land to and against subsequent owners and successors in interest, and is not, nor shall it operate or be construed as, a personal covenant of Landlord, except to the extent of the Landlord’s interest in the Premises, and this covenant and any and all other covenants of Landlord contained in this Lease shall be binding upon Landlord and upon such subsequent owners or successors in interest of Landlord’s interest under this Lease, including ground or master lessees, to the extent of their respective interests, as and when they shall acquire same and then only for so long as they shall retain such interest. 
16.4Surrender 
(A)No act or thing done by Landlord during the Lease Term shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept such surrender shall be valid, unless in writing signed by Landlord. No employee of Landlord or of Landlord’s agents shall have any power to accept the keys of the Premises as an acceptance of a surrender of the Premises prior to the termination of this Lease; provided, however, that the foregoing shall not apply to the delivery of keys to Landlord or its agents in its (or their) capacity as managing 

agent or for purpose of emergency access. In any event, however, the delivery of keys to any employee of Landlord or of Landlord’s agents shall not operate as a termination of the Lease or a surrender of the Premises. 
(B)Upon the expiration or earlier termination of the Lease Term, Tenant shall surrender the Premises to Landlord in the condition as required by Sections 8.1 and 9.5, first removing all goods and effects of Tenant and completing such other removals as may be permitted or required pursuant to Section 9.5. 
16.5Brokerage 
(A)Tenant warrants and represents that Tenant has not dealt with any broker in connection with the consummation of this Lease other than the broker, person or firm designated in Section 1.1 hereof; and in the event any claim is made against the Landlord relative to dealings with brokers other than the broker designated in Section 1.1 hereof, Tenant shall defend the claim against Landlord with counsel of Landlord’s selection first reasonably approved by Tenant and save harmless and indemnify Landlord on account of loss, cost or damage which may arise by reason of such claim.  
(B)Landlord warrants and represents that Landlord has not dealt with any broker in connection with the consummation of this Lease other than the broker, person or firm, if any, designated in Section 1.1 hereof; and in the event any claim is made against the Tenant relative to dealings by Landlord with brokers other than the broker designated in Section 1.1 hereof, Landlord shall defend the claim against Tenant with counsel of Tenant’s first reasonably approved by Landlord selection and save harmless and indemnify Tenant on account of loss, cost or damage which may arise by reason of such claim. Landlord agrees that it shall be solely responsible for the payment of brokerage commissions to the broker, person or firm designated in Section 1.1 hereof in connection with the Original Lease Term. 
16.6Invalidity of Particular Provisions 
If any term or provision of this Lease, including but not limited to any waiver of contribution or claims, indemnity, obligation, or limitation of liability or of damages, or the application thereof to any person or circumstance shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term or provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby, and each term and provision of this Lease shall be valid and be enforced to the fullest extent permitted by law. 
16.7Provisions Binding, Etc. 
The obligations of this Lease shall run with the land, and except as herein otherwise provided, the terms hereof shall be binding upon and shall inure to the benefit of the successors and assigns, respectively, of Landlord and Tenant and, if Tenant shall be an individual, upon and to his heirs, executors, administrators, successors and assigns. Each term and each provision of this Lease to be performed by Tenant shall be construed to be both a covenant and a condition. The reference contained to successors and assigns of Tenant is not intended to constitute a consent to assignment by Tenant, but has reference only to those instances in which Landlord may have later given consent to a particular assignment as required by the provisions of Article XII hereof.  
16.8Recording; Confidentiality 
Each of Landlord and Tenant agree not to record the within Lease, but each party hereto agrees, on the request of the other, to execute a so-called Notice of Lease or short form lease in form recordable and complying with applicable law and reasonably satisfactory to Landlord’s and Tenant’s attorneys. In no event shall such document set forth the rent or other charges payable by Tenant under this Lease; and any such document shall expressly state that it is executed pursuant to the provisions contained in this Lease, and is not intended to vary the terms and conditions of this Lease.  
Each party hereto agrees that this Lease, the terms contained herein, and all information referring to this Lease obtained prior to execution of this Lease and within the Lease Term will be treated as strictly confidential and except as required by law or any applicable securities exchange, and except as required in connection with any enforcement of the terms of this Lease, neither party shall disclose the same to any third party without the prior written consent of the other party, other than to the disclosing party’s partners, lenders, accountants and attorneys who have been advised of the confidentiality provisions contained herein and agree to be bound by the same. In the event Tenant is required by law to provide this Lease or disclose any of its terms, Tenant shall give Landlord prompt notice of such requirement prior to making disclosure so that Landlord may seek an appropriate protective order. If failing the entry of a protective order 

Tenant is compelled to make disclosure, Tenant shall only disclose portions of the Lease which Tenant is required to disclose and will exercise reasonable efforts to obtain assurance that confidential treatment will be accorded to the information so disclosed. 
The obligation not to disclose confidential information shall continue throughout the Lease Term and for one (1) year after the expiration or earlier termination of this Lease. 
16.9Notices and Time for Action 
Whenever, by the terms of this Lease, notice shall or may be given either to Landlord or to Tenant, such notices shall be in writing and shall be sent by hand, registered or certified mail, or overnight or other commercial courier, postage or delivery charges, as the case may be, prepaid as follows: 
If intended for Landlord, addressed to Landlord at the address set forth in Article I of this Lease (or to such other address or addresses as may from time to time hereafter be designated by Landlord by like notice) with a copy to Landlord, Attention: Regional General Counsel. 
If intended for Tenant, addressed to Tenant at the address set forth in Article I of this Lease except that from and after the Commencement Date the address of Tenant shall be the Premises (or to such other address or addresses as may from time to time hereafter be designated by Tenant by like notice). 
Except as otherwise provided herein, all such notices shall be effective when received; provided, that (i) if receipt is refused, notice shall be effective upon the first occasion that such receipt is refused, (ii) if the notice is unable to be delivered due to a change of address of which no notice was given, notice shall be effective upon the date such delivery was attempted, (iii) if the notice address is a post office box number, notice shall be effective the day after such notice is sent as provided hereinabove or (iv) if the notice is to a foreign address, notice shall be effective two (2) days after such notice is sent as provided hereinabove. 
Where provision is made for the attention of an individual or department, the notice shall be effective only if the wrapper in which such notice is sent is addressed to the attention of such individual or department. 
Any notice given by an attorney on behalf of Landlord or by Landlord’s managing agent shall be considered as given by Landlord and shall be fully effective. Any notice given by an attorney on behalf of Tenant shall be considered as given by Tenant and shall be fully effective. 
Time is of the essence with respect to any and all notices and periods for giving of notice or taking any action thereto under this Lease. 
16.10When Lease Becomes Binding and Authority 
Employees or agents of Landlord have no authority to make or agree to make a lease or any other agreement or undertaking in connection herewith. The submission of this document for examination and negotiation does not constitute an offer to lease, or a reservation of, or option for, the Premises, and this document shall become effective and binding only upon the execution and delivery hereof by both Landlord and Tenant. All negotiations, considerations, representations and understandings between Landlord and Tenant are incorporated herein and may be modified or altered only by written agreement between Landlord and Tenant, and no act or omission of any employee or agent of Landlord shall alter, change or modify any of the provisions hereof. Landlord and Tenant hereby represent and warrant to the other that all necessary action has been taken to enter this Lease and that the person signing this Lease on behalf of Landlord and Tenant has been duly authorized to do so. 
16.11Paragraph Headings 
The paragraph headings throughout this instrument are for convenience and reference only, and the words contained therein shall in no way be held to explain, modify, amplify or aid in the interpretation, construction or meaning of the provisions of this Lease. 
16.12Rights of Mortgagee 
This Lease shall be subject and subordinate to any mortgage now or hereafter on the Building (or any part thereof), and to all renewals, modifications, consolidations, replacements and extensions thereof and all substitutions therefor, provided that in the case of a future mortgage the holder of such mortgage agrees to recognize the right of Tenant to use and occupy the Premises upon the payment of rent and other charges payable by Tenant under this Lease and the performance by Tenant of Tenant’s obligations hereunder. In confirmation of such subordination and recognition, Tenant shall execute and deliver promptly such instruments of subordination as such mortgagee may reasonably request, subject to receipt of such instruments of recognition from such mortgagee as Tenant may reasonably request (Tenant hereby agreeing to pay any legal or other fees charged by the mortgagee in connection with providing the same). In the event that any mortgagee or its respective successor in title shall succeed to the interest of Landlord, then this Lease shall nevertheless continue in full force and effect and Tenant shall and does hereby agree to attorn to such mortgagee or successor and to recognize such mortgagee or successor as its landlord. If any holder of a mortgage which includes the Premises, executed and 

recorded prior to the Date of this Lease, shall so elect, this Lease, and the rights of Tenant hereunder, shall be superior in right to the rights of such holder, with the same force and effect as if this Lease had been executed, delivered and recorded, or a statutory notice hereof recorded, prior to the execution, delivery and recording of any such mortgage. The election of any such holder shall become effective upon either notice from such holder to Tenant in the same fashion as notices from Landlord to Tenant are to be given hereunder or by the recording in the appropriate registry or recorder’s office of an instrument in which such holder subordinates its rights under such mortgage to this Lease. 
If in connection with obtaining financing a bank, insurance company, pension trust or other institutional lender shall request reasonable modifications in this Lease as a condition to such financing, Tenant will not unreasonably withhold, delay or condition its consent thereto, provided that such modifications do not increase the monetary obligations of Tenant hereunder or materially adversely affect the leasehold interest hereby created or Tenant’s rights hereunder. 
16.13Rights of Ground Lessor 
If Landlord’s interest in property (whether land only or land and buildings) which includes the Premises is acquired by another party and simultaneously leased back to Landlord herein, the holder of the ground lessor’s interest in such lease shall enter into a recognition agreement with Tenant simultaneously with the sale and leaseback, wherein the ground lessor will agree to recognize the right of Tenant to use and occupy the Premises upon the payment of Annual Fixed Rent, Additional Rent and other charges payable by Tenant under this Lease and the performance by Tenant of Tenant’s obligations hereunder, and wherein Tenant shall agree to attorn to such ground lessor as its Landlord and to perform and observe all of the tenant obligations hereunder, in the event such ground lessor succeeds to the interest of Landlord hereunder under such ground lease. 
16.14Notice to Mortgagee and Ground Lessor  
After receiving notice from any person, firm or other entity that it holds a mortgage which includes the Premises as part of the mortgaged premises, or that it is the ground lessor under a lease with Landlord as ground lessee, which includes the Premises as a part of the leased premises, no notice from Tenant to Landlord shall be effective unless and until a copy of the same is given to such holder or ground lessor at the address as specified in said notice (as it may from time to time be changed), and the curing of any of Landlord’s defaults by such holder or ground lessor within a reasonable time after such notice (including a reasonable time to obtain possession of the premises if the mortgagee or ground lessor elects to do so) shall be treated as performance by Landlord. For the purposes of this Section 16.14, the term “mortgage” includes a mortgage on a leasehold interest of Landlord (but not one on Tenant’s leasehold interest). If any mortgage is listed on Exhibit F then the same shall constitute notice from the holder of such mortgage for the purposes of this Section 16.14. 
16.15Assignment of Rents 
With reference to any assignment by Landlord of Landlord’s interest in this Lease, or the rents payable hereunder, conditional in nature or otherwise, which assignment is made to the holder of a mortgage or ground lease on property which includes the Premises, Tenant agrees: 
(a)That the execution thereof by Landlord, and the acceptance thereof by the holder of such mortgage, or the ground lessor, shall never be treated as an assumption by such holder or ground lessor of any of the obligations of Landlord hereunder, unless such holder, or ground lessor, shall, by notice sent to Tenant, specifically otherwise elect; and  
(b)That, except as aforesaid, such holder or ground lessor shall be treated as having assumed Landlord’s obligations hereunder only upon foreclosure of such holder’s mortgage and the taking of possession of the Premises, or, in the case of a ground lessor, the assumption of Landlord’s position hereunder by such ground lessor. In no event shall the acquisition of title to the Building and the land on which the same is located by a purchaser which, simultaneously therewith, leases the entire Building or such land back to the seller thereof be treated as an assumption, by operation of law or otherwise, of Landlord’s obligations hereunder, but Tenant shall look solely to such seller-lessee, and its successors from time to time in title, for performance of Landlord’s obligations hereunder. In any such event, this Lease shall be subject and subordinate to the lease to such purchaser provided that such purchaser-lessor agrees to recognize the right of Tenant to use and occupy the Premises upon the payment of rent and all other charges payable by Tenant under this Lease and the performance by Tenant of Tenant’s obligations under this Lease. For all purposes, such seller-lessee, and its successors in title, shall be the landlord hereunder unless and until Landlord’s position shall have been assumed by such purchaser-lessor.  

16.16Status Report and Financial Statements 
Recognizing that Landlord may find it necessary to establish to third parties, such as accountants, banks, potential or existing mortgagees, potential purchasers or the like, the then current status of performance hereunder, Tenant, within ten (10) days after the request of Landlord made from time to time, will furnish to Landlord, or any existing or potential holder of any mortgage encumbering the Premises, the Building or the Prudential Center, or any potential purchaser of the Premises, the Building, or the Prudential Center (each an “Interested Party”) a statement of the status of any matter pertaining to this Lease, including, without limitation, acknowledgments that (or the extent to which) each party is in compliance with its obligations under the terms of this Lease. In addition, Tenant shall deliver to Landlord, or any Interested Party designated by Landlord, financial statements of Tenant, and any guarantor of Tenant’s obligations under this Lease, as reasonably requested by Landlord including, but not limited to, financial statements for the past three (3) years. Any such status statement or financial statement delivered by Tenant pursuant to this Section 16.16 (or any financial statement otherwise delivered by Tenant in connection with this Lease or any future amendment hereto) may be relied upon by any Interested Party.  
16.17Self-Help 
If Tenant shall at any time fail to make any payment or perform any act which Tenant is obligated to make or perform under this Lease and (except in the case of emergency) if the same continues unpaid or unperformed beyond applicable grace periods, then Landlord may, but shall not be obligated so to do, after ten (10) days’ notice to and demand upon Tenant, or without notice to or demand upon Tenant in the case of any emergency, and without waiving, or releasing Tenant from, any obligations of Tenant in this Lease contained, make such payment or perform such act which Tenant is obligated to perform under this Lease in such manner and to such extent as may be reasonably necessary, and, in exercising any such rights, pay any costs and expenses, employ counsel and incur and pay reasonable attorneys’ fees. All sums so paid by Landlord and all reasonable and necessary costs and expenses of Landlord incidental thereto, together with interest thereon at the annual rate equal to the sum of (a) the Base Rate from time to time announced by Bank of America, N.A. or its successor as its Base Rate and (b) two percent (2%) (but in no event greater than the maximum rate permitted by applicable law), from the date of the making of such expenditures by Landlord, shall be deemed to be Additional Rent and, except as otherwise in this Lease expressly provided, shall be payable to the Landlord on demand, and if not promptly paid shall be added to any rent then due or thereafter becoming due under this Lease, and Tenant covenants to pay any such sum or sums with interest as aforesaid, and Landlord shall have (in addition to any other right or remedy of Landlord) the same rights and remedies in the event of the non-payment thereof by Tenant as in the case of default by Tenant in the payment of Annual Fixed Rent. 
16.18Holding Over 
Any holding over by Tenant after the expiration or earlier termination of the Lease Term shall be treated as a tenancy at sufferance and shall be on the terms and conditions as set forth in this Lease, as far as applicable except that Tenant shall pay as a use and occupancy charge an amount equal to 200% of the greater of (x) the Annual Fixed Rent and Additional Rent calculated (on a daily basis) at the highest rate payable under the terms of this Lease or (y) the fair market rental value of the Premises, in each case for the period measured from the day on which Tenant’s hold-over commences and terminating on the day on which Tenant vacates the Premises. In addition, Tenant shall save Landlord, its agents and employees harmless and will exonerate, defend and indemnify Landlord, its agents and employees from and against any and all damages which Landlord may suffer on account of Tenant’s hold-over in the Premises after the expiration or prior termination of the Lease Term. Nothing in the foregoing nor any other term or provision of this Lease shall be deemed to permit Tenant to retain possession of the Premises or hold over in the Premises after the expiration or earlier termination of the Lease Term. All property which remains in the Building or the Premises after the expiration or termination of this Lease shall be conclusively deemed to be abandoned and may either be retained by Landlord as its property or sold or otherwise disposed of in such manner as Landlord may see fit. If any part thereof shall be sold, then Landlord may receive the proceeds of such sale and apply the same, at its option against the expenses of the sale, the cost of moving and storage, any arrears of rent or other charges payable hereunder by Tenant to Landlord and any damages to which Landlord may be entitled under this Lease and at law and in equity. 
16.19Entry by Landlord 
Landlord, and its duly authorized representatives, shall, upon reasonable prior notice (except in the case of emergency), have the right to enter the Premises at all reasonable times (except at any time in the case of emergency) for the purposes of inspecting the condition of same and making such repairs, alterations, additions or improvements thereto as may be necessary if Tenant fails to do so as required hereunder (but the Landlord shall have no duty whatsoever to make any such inspections, repairs, alterations, additions or improvements except as otherwise provided in Sections 4.1, 7.1 and 7. 2), and to show the Premises to prospective tenants 

during the twelve (12) months preceding expiration of the Lease Term as it may have been extended and at any reasonable time during the Lease Term to show the Premises to prospective purchasers and mortgagees. 
In the event Tenant sends a notice alleging the existence of a dangerous or unsafe condition, any requirements for prior notice or limitations on Landlord’s access to the Premises contained in this Lease shall be deemed waived by Tenant so that Landlord may immediately exercise its rights under this Section 16.19 and Section 16.17 in such manner as Landlord deems necessary in its sole discretion to remedy such dangerous or unsafe condition. 
16.20Tenant’s Payments 
Each and every payment and expenditure, other than Annual Fixed Rent, shall be deemed to be Additional Rent hereunder, whether or not the provisions requiring payment of such amounts specifically so state, and shall be payable, unless otherwise provided in this Lease, within ten (10) days after written demand by Landlord, and in the case of the non-payment of any such amount, Landlord shall have, in addition to all of its other rights and remedies, all the rights and remedies available to Landlord hereunder or by law in the case of non-payment of Annual Fixed Rent. Unless expressly otherwise provided in this Lease, the performance and observance by Tenant of all the terms, covenants and conditions of this Lease to be performed and observed by Tenant shall be at Tenant’s sole cost and expense. If Tenant has not objected to any statement of Additional Rent which is rendered by Landlord to Tenant within ninety (90) days after Landlord has rendered the same to Tenant, then the same shall be deemed to be a final account between Landlord and Tenant not subject to any further dispute. In the event that Tenant shall seek Landlord’s consent or approval under this Lease, then Tenant shall reimburse Landlord, upon demand, as Additional Rent, for all reasonable costs and expenses, including legal and architectural costs and expenses, incurred by Landlord in processing such request, whether or not such consent or approval shall be given. Notwithstanding anything in this Lease to the contrary, if Landlord or any affiliate of Landlord has elected to qualify as a real estate investment trust (“REIT”), any service required or permitted to be performed by Landlord pursuant to this Lease, the charge or cost of which may be treated as impermissible tenant service income under the laws governing a REIT, may be performed by a taxable REIT subsidiary that is affiliated with either Landlord or Landlord’s property manager, an independent contractor of Landlord or Landlord’s property manager (the “Service Provider”). If Tenant is subject to a charge under this Lease for any such service, then, at Landlord’s direction, Tenant will pay such charge either to Landlord for further payment to the Service Provider or directly to the Service Provider, and, in either case, (i) Landlord will credit such payment against Additional Rent due from Tenant under this Lease for such service, and (ii) such payment to the Service Provider will not relieve Landlord from any obligation under the Lease concerning the provisions of such service. 
16.21Late Payment 
If Landlord shall not have received any payment or installment of Annual Fixed Rent or Additional Rent (the “Outstanding Amount”) on or before the date on which the same first becomes payable under this Lease (the “Due Date”), the amount of such payment or installment shall incur a late charge equal to the sum of: (a) five percent (5%) of the Outstanding Amount for administration and bookkeeping costs associated with the late payment and (b) interest on the Outstanding Amount from the Due Date through and including the date such payment or installment is received by Landlord, at a rate equal to the lesser of (i) the rate announced by Bank of America, N.A. (or its successor) from time to time as its prime or base rate (or if such rate is no longer available, a comparable rate reasonably selected by Landlord), plus two percent (2%), or (ii) the maximum applicable legal rate, if any. Such interest shall be deemed Additional Rent and shall be paid by Tenant to Landlord upon demand. 
16.22Counterparts 
This Lease may be executed in several counterparts, each of which shall be deemed an original, and such counterparts shall constitute but one and the same instrument. 
16.23Entire Agreement 
This Lease constitutes the entire agreement between the parties hereto, Landlord’s managing agent and their respective affiliates with respect to the subject matter hereof and thereof and supersedes all prior dealings between them with respect to such subject matter, and there are no verbal or collateral understandings, agreements, representations or warranties not expressly set forth in this Lease. No subsequent alteration, amendment, change or addition to this Lease shall be binding upon Landlord or Tenant, unless reduced to writing and signed by the party or parties to be charged therewith. 
16.24Landlord Liability 
Tenant shall neither assert nor seek to enforce any claim for breach of this Lease against any of Landlord’s assets other than Landlord’s interest in the Building, and Tenant agrees to look solely to such interest for the satisfaction of any liability of Landlord under this Lease, it being specifically agreed that neither Landlord, nor 

any successor holder of Landlord’s interest hereunder, nor any beneficiary of any Trust of which any person from time to time holding Landlord’s interest is Trustee, nor any such Trustee, nor any member, manager, partner, director or stockholder nor Landlord’s managing agent shall ever be personally liable for any such liability. This paragraph shall not limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord or Landlord’s successors-in-interest, or to take any other action which shall not involve the personal liability of Landlord, or of any successor holder of Landlord’s interest hereunder, or of any beneficiary of any trust of which any person from time to time holding Landlord’s interest is Trustee, or of any such Trustee, or of any manager, member, partner, director or stockholder of Landlord or of Landlord’s managing agent, to respond in monetary damages from Landlord’s assets other than Landlord’s interest in said Building, as aforesaid, but in no event shall Tenant have the right to terminate or cancel this Lease or to withhold rent or to set-off any claim or damages against rent as a result of any default by Landlord or breach by Landlord of its covenants or any warranties or promises hereunder, except in the case of a wrongful eviction of Tenant from the demised premises (constructive or actual) by Landlord continuing after notice to Landlord thereof and a reasonable opportunity for Landlord to cure the same.
In the event that Landlord shall be determined to have wrongfully withheld any consent or approval under this Lease, the sole recourse and remedy of the Tenant in respect thereof shall be to specifically enforce Landlord’s obligation to grant such consent or approval, and in no event shall the Landlord be responsible for any damages of whatever nature in respect of its failure to give such consent or approval nor shall the same otherwise affect the obligations of the Tenant under this Lease or act as any termination of this Lease.   
In no event shall Landlord or Tenant ever be liable to the other party for any indirect or consequential damages, or for loss of profits or the like suffered from whatever cause; provided however, the foregoing shall not in any way apply to or otherwise limit Landlord’s remedies with respect to any hold over of Tenant after the expiration or earlier termination of this Lease. 
16.25No Partnership 
The relationship of the parties hereto is that of landlord and tenant and no partnership, joint venture or participation is hereby created. 
16.26Letter of Credit 
Concurrently with the execution of this Lease, Tenant shall pay to Landlord a security deposit in the amount of Eighty-Eight Thousand Thirteen and 67/100 Dollars ($88,013.67) and Landlord shall hold the same, throughout the Lease Term, unless sooner returned to Tenant as provided in this Section 16.26, as security for the performance by Tenant of all obligations on the part of Tenant to be performed under this Lease. Such deposit shall be in the form of an irrevocable, unconditional, negotiable letter of credit (the “Letter of Credit”). The Letter of Credit shall (i) be issued by and drawn on a bank reasonably approved by Landlord and at a minimum having a long term issuer credit rating from Standard and Poor’s Professional Rating Service of A or a comparable rating from Moody’s Professional Rating Service, (ii) be substantially in the form attached hereto as Exhibit G, (iii) permit one or more draws thereunder to be made accompanied only by certification by Landlord or Landlord’s managing agent that pursuant to the terms of this Lease, Landlord is entitled to draw upon such Letter of Credit, (iv) permit transfers at any time without charge, (v) permit presentment in Boston, Massachusetts and (vi) provide that any notices to Landlord be sent to the notice address provided for Landlord in this Lease. If the credit rating for the issuer of such Letter of Credit falls below the standard set forth in (i) above or if the financial condition of such issuer changes in any other material adverse way or if any trustee, receiver or liquidator shall be appointed for the issuer, Landlord shall have the right to require that Tenant provide a substitute letter of credit that complies in all respects with the requirements of this Section, and Tenant’s failure to provide the same within thirty (30) days following Landlord’s written demand therefor shall entitle Landlord to immediately draw upon the Letter of Credit. Any such Letter of Credit shall be for a term of two (2) years (or for one (1) year if the issuer thereof regularly and customarily only issues letters of credit for a maximum term of one (1) year) and shall in either case provide for automatic renewals through the date which is ninety 
(90) days subsequent to the scheduled expiration of this Lease (as the same may be extended). Any failure or refusal of the issuer to honor the Letter of Credit shall be at Tenant’s sole risk and shall not relieve Tenant of its obligations hereunder with regard to the security deposit. Upon the occurrence of any default of Tenant, Landlord shall have the right from time to time without prejudice to any other remedy Landlord may have on account thereof, to draw on all or any portion of such deposit held as a Letter of Credit and to apply the proceeds of such Letter of Credit or any cash held as such deposit, or any part thereof, to Landlord’s damages arising from such default on the part of Tenant under the terms of this Lease. If Landlord so applies all or any portion of such deposit, Tenant shall within seven (7) days after notice from Landlord deposit cash with Landlord in an amount sufficient to restore such deposit to the full amount stated in this Section 16.26. While Landlord holds any cash 

deposit Landlord shall have no obligation to pay interest on the same and shall have the right to commingle the same with Landlord’s other funds. Neither the holder of a mortgage nor the Landlord in a ground lease on property which includes the Premises shall ever be responsible to Tenant for the return or application of any such deposit, whether or not it succeeds to the position of Landlord hereunder, unless such deposit shall have been received in hand by such holder or ground Landlord. 
Tenant not then being in default and having performed all of its obligations under this Lease, including the payment of all Annual Fixed Rent, Landlord shall return the deposit, or so much thereof as shall not have theretofore been applied in accordance with the terms of this Section 16.26, to Tenant on the expiration or earlier termination of the Lease Term (as the same may have been extended) and surrender possession of the Premises by Tenant to Landlord in the condition required in the Lease at such time. 
16.27Signage 
Landlord shall install, at its sole cost and expense, Building-standard multi-tenant directional signage for Tenant within the elevator lobby on the twenty-fourth (24th) floor of the Building.  Subject to Landlord’s prior approval as to location, size and design, Tenant may install, at its sole cost and expense, identification signage at the entrance to the Premises.  Tenant shall be obligated to remove such identification signage at the expiration or termination of the Lease Term and to repair any damage caused by such removal. 
16.28Governing Law 
This Lease shall be governed exclusively by the provisions hereof and by the law of The Commonwealth of Massachusetts, as the same may from time to time exist. 
16.29Waiver of Trial by Jury  
To induce Landlord to enter into this Lease, the Tenant hereby waives any right to trial by jury in any action, proceeding or counterclaim brought by either Landlord or Tenant on any matters whatsoever arising out of or any way connected with this Lease, the relationship of the Landlord and the Tenant, the Tenant’s use or occupancy of the premises and/or any claim of injury or damage, including but not limited to, any summary process eviction action. 
16.30Electronic Signatures  
The parties acknowledge and agree that this Lease may be executed by electronic signature, which shall be considered as an original signature for all purposes and shall have the same force and effect as an original signature. Without limitation, “electronic signature” shall include faxed versions of an original signature or electronically scanned and transmitted versions (e.g., via pdf) of an original signature.
