 Exhibit 10.1 

FORM OF INDEMNIFICATION AGREEMENT 

[(WITH SECONDARY FUND INDEMNIFICATION)] 

THIS INDEMNIFICATION AGREEMENT (the “Agreement”) is made and entered into as of
[—] between Civitas Therapeutics, Inc., a Delaware corporation (the “Company”), and [—] (“Indemnitee”). 

WITNESSETH THAT: 
 WHEREAS,
highly competent persons have become more reluctant to serve corporations as directors or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and
actions against them arising out of their service to and activities on behalf of the corporation; 
 WHEREAS, although the furnishing of
liability insurance to protect persons serving corporations and their subsidiaries from certain liabilities has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes
that, given current market conditions and trends, such insurance may be available to it in the future only at higher premiums and with more exclusions. At the same time, directors, officers, and other persons in service to corporations or business
enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among other things, matters that traditionally would have been brought only against the corporation itself. The Bylaws and Amended and Restated
Certificate of Incorporation of the Company require indemnification of the officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware
(“DGCL”). The Bylaws, the Amended and Restated Certificate of Incorporation and the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts may be
entered into between the Company and members of the board of directors, officers and other persons with respect to indemnification; 

WHEREAS, the uncertainties relating to liability insurance and to indemnification have increased the difficulty of attracting and retaining
such persons; 
 WHEREAS, the Board of Directors has determined that the increased difficulty in attracting and retaining such persons is
detrimental to the best interests of the Company’s stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on
behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

WHEREAS, this Agreement is a supplement to and in furtherance of the By-laws and Amended and Restated Certificate of Incorporation of the
Company and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; 

 WHEREAS, Indemnitee does not regard the protection available under the Company’s By-laws and
Amended and Restated Certificate of Incorporation and insurance as adequate in the present circumstances, and may not be willing to serve as an officer or director without adequate protection, and the Company desires Indemnitee to serve in such
capacity. Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that he be so indemnified; and 

[WHEREAS, Indemnitee has, or may have, certain rights to indemnification and/or insurance provided by
[—] which Indemnitee and [—] intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the
Company’s acknowledgement and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve on the Board.] 

NOW, THEREFORE, in consideration of Indemnitee’s agreement to serve as a director from and after the date hereof, the parties hereto
agree as follows: 
 1. Indemnity of Indemnitee. The Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest
extent permitted by law, as such may be amended from time to time. In furtherance of the foregoing indemnification, and without limiting the generality thereof: 

(a) Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of
indemnification provided in this Section 1(a) if, by reason of his Corporate Status (as hereinafter defined), the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (as hereinafter defined) other than
a Proceeding by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses (as hereinafter defined), judgments, penalties, fines and amounts paid in settlement actually and
reasonably incurred by him, or on his behalf, in connection with such Proceeding or any claim, issue or matter therein, if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best
interests of the Company, and with respect to any criminal Proceeding, had no reasonable cause to believe the Indemnitee’s conduct was unlawful. 

(b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this
Section 1(b) if, by reason of his Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the Company. Pursuant to this Section 1(b),
Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by the Indemnitee, or on the Indemnitee’s behalf, in connection with such Proceeding if the Indemnitee acted in good faith and in a manner the Indemnitee
reasonably believed to be in or not opposed to the best interests of the Company; provided, however, if applicable law so provides, no indemnification against such Expenses shall be made in respect of any claim, issue or matter in such Proceeding as
to which Indemnitee shall have been adjudged to be liable to the Company unless and to the extent that the Court of Chancery of the State of Delaware shall determine that such indemnification may be made. 

  
 -2- 

 (c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful.
Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, he shall be indemnified to the maximum extent
permitted by law, as such may be amended from time to time, against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the
merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him or on his behalf in connection with each
successfully resolved claim, issue or matter. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result
as to such claim, issue or matter. 
 2. Additional Indemnity. 

(a) In addition to, and without regard to any limitations on, the indemnification provided for in Section 1 of this Agreement,
the Company shall and hereby does indemnify and hold harmless Indemnitee against all Expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by him or on his behalf if, by reason of his Corporate Status,
he is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by or in the right of the Company), including, without limitation, all liability arising out of the negligence or active or passive wrongdoing of
Indemnitee. The only limitation that shall exist upon the Company’s obligations pursuant to this Agreement shall be that the Company shall not be obligated to make any payment to Indemnitee that is finally determined (under the procedures, and
subject to the presumptions, set forth in Sections 6 and 7 hereof) to be unlawful. 
 [(b) If (i) Indemnitee is or was
affiliated with one or more venture capital funds or [—] (an “Appointing Stockholder”), and (ii) the Appointing Stockholder is, or is threatened to be made, a party to or a
participant in any Proceeding, relating to or arising by reason of Appointing Stockholder’s position as a stockholder of, or lender to, the Company, or Appointing Stockholder’s appointment of or affiliation with Indemnitee or any other
director, including without limitation any alleged misappropriation of a Company asset or corporate opportunity, any claim of misappropriation or infringement of intellectual property relating to the Company, any alleged false or misleading
statement or omission made by the Company (or on its behalf) or its employees or agents, or any allegation of inappropriate control or influence over the Company or its Board members, officers, equity holders or debt holders, then the Appointing
Stockholder shall be entitled to all of the indemnification rights and remedies under this Agreement pursuant to this Agreement (and, for clarity, subject to the same notice, consent to jurisdiction and other terms and conditions of this Agreement)
as if the Appointing Stockholder were the Indemnitee. The Company and Indemnitee agree that the Appointing Stockholder is an express third party beneficiary of the terms of this Section 2(b).] 

3. Contribution. 
 (a)
Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if
joined in such action, suit or proceeding), the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such action, suit or proceeding without requiring Indemnitee to contribute to such payment and the Company
hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Company shall not enter into any settlement of any action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined
in such action, suit or proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee. 

(b) Without diminishing or impairing the obligations of the Company set forth in the preceding subparagraph, if, for any reason, Indemnitee
shall elect or be required to pay all or any portion of any judgment or settlement in any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit
or proceeding), the Company shall contribute to the amount of 

  
 -3- 

 
Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company and all
officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction from
which such action, suit or proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the Company and
all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the
events that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which the Law may require to be considered. The relative fault of the Company and all officers, directors or employees of
the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, shall be determined by reference to, among other things, the
degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary and the degree to which their conduct is active or passive. 

(c) The Company hereby agrees to fully indemnify and hold Indemnitee harmless from any claims of contribution which may be brought by
officers, directors or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee. 
 (d) To the fullest
extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by
Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed
fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding;
and/or (ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 

4. Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is,
by reason of his Corporate Status, a witness, or is made (or asked to) respond to discovery requests, in any Proceeding to which Indemnitee is not a party, he shall be indemnified against all Expenses actually and reasonably incurred by him or on
his behalf in connection therewith. 
 5. Advancement of Expenses. Notwithstanding any other provision of this Agreement, the Company
shall advance all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Corporate Status within thirty (30) days after the receipt by the Company of a statement or statements from
Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by

  
 -4- 

 
Indemnitee and shall include or be preceded or accompanied by a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that
Indemnitee is not entitled to be indemnified against such Expenses. Any advances and undertakings to repay pursuant to this Section 5 shall be unsecured and interest free. The Company shall not seek from a court, or consent to the entry
of, a “bar order” which would have the effect of prohibiting or limiting Indemnitee’s rights under this Agreement to receive advancement of Expenses. 

6. Procedures and Presumptions for Determination of Entitlement to Indemnification. It is the intent of this Agreement to secure for
Indemnitee rights of indemnity that are as favorable as may be permitted under the DGCL and public policy of the State of Delaware. Accordingly, the parties agree that the following procedures and presumptions shall apply in the event of any
question as to whether Indemnitee is entitled to indemnification under this Agreement: 
 (a) To obtain indemnification under this
Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent
Indemnitee is entitled to indemnification. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board of Directors in writing that Indemnitee has requested indemnification. Notwithstanding the
foregoing, any failure of Indemnitee to provide such a request to the Company, or to provide such a request in a timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee unless, and to the extent that, such
failure actually and materially prejudices the interests of the Company. 
 (b) Upon written request by Indemnitee for indemnification
pursuant to the first sentence of Section 6(a) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following three methods, which shall be at the election of the
Board of Directors: (1) by a majority vote of the disinterested directors, even though less than a quorum, (2) by a committee of disinterested directors designated by a majority vote of the disinterested directors, even though less than a
quorum, or (3) if there are no disinterested directors or if the disinterested directors so direct, by Independent Counsel (as hereinafter defined) in a written opinion to the Board of Directors, a copy of which shall be delivered to the
Indemnitee. For purposes hereof, disinterested directors are those members of the Board of Directors of the Company who are not parties to the Proceeding in respect of which indemnification is sought by Indemnitee. 

(c) If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 6(b) hereof,
the Independent Counsel shall be selected as provided in this Section 6(c). The Independent Counsel shall be selected by the Board of Directors. Indemnitee may, within 10 days after such written notice of selection shall have been given,
deliver to the Company a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel”
as defined in Section 13 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent

  
 -5- 

 
Counsel. If a written objection is made and substantiated, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has
determined that such objection is without merit. If, within 20 days after submission by Indemnitee of a written request for indemnification pursuant to Section 6(a) hereof, no Independent Counsel shall have been selected and not objected
to, either the Company or Indemnitee may petition the Court of Chancery of the State of Delaware or other court of competent jurisdiction for resolution of any objection which shall have been made by the Indemnitee to the Company’s selection of
Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so
appointed shall act as Independent Counsel under Section 6(b) hereof. The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to
Section 6(b) hereof, and the Company shall pay all reasonable fees and expenses incident to the procedures of this Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed. 

(d) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such
determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. Neither the
failure of the Company (including by its directors or independent legal counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee
has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or independent legal counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or
create a presumption that Indemnitee has not met the applicable standard of conduct. 
 (e) Indemnitee shall be deemed to have acted in
good faith if Indemnitee’s action is based on the records or books of account of the Enterprise (as hereinafter defined), including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course
of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care
by the Enterprise. In addition, the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this
Agreement. Whether or not the foregoing provisions of this Section 6(e) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner he reasonably believed to be in or not opposed
to the best interests of the Company. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 

(f) If the person, persons or entity empowered or selected under Section 6 to determine whether Indemnitee is entitled to
indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall be deemed to have been made and Indemnitee
shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a 

  
 -6- 

 
material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a
prohibition of such indemnification under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making such determination
with respect to entitlement to indemnification in good faith requires such additional time to obtain or evaluate documentation and/or information relating thereto. 

(g) Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to
indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee
and reasonably necessary to such determination. Any Independent Counsel or member of the Board of Directors shall act reasonably and in good faith in making a determination regarding the Indemnitee’s entitlement to indemnification under this
Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the
determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 

(h) The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a party to avoid
expense, delay, distraction, disruption and uncertainty. In the event that any Proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without limitation, settlement of such
Proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise in such Proceeding. Anyone seeking to overcome this presumption shall have the burden of proof
and the burden of persuasion by clear and convincing evidence. 
 (i) The termination of any Proceeding or of any claim, issue or matter
therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or
create a presumption that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable
cause to believe that his conduct was unlawful. 
 7. Remedies of Indemnitee. 

(a) In the event that (i) a determination is made pursuant to Section 6 of this Agreement that Indemnitee is not entitled to
indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to indemnification is made pursuant to
Section 6(b) of this Agreement within 90 days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to this Agreement within ten (10) days after receipt by the
Company of a written request therefor or (v) payment of indemnification is not 

  
 -7- 

 
made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification or such determination is deemed to have been made pursuant to
Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other court of competent jurisdiction, of Indemnitee’s entitlement to such indemnification.
Indemnitee shall commence such proceeding seeking an adjudication within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 7(a). The Company shall not oppose
Indemnitee’s right to seek any such adjudication. 
 (b) In the event that a determination shall have been made pursuant to
Section 6(b) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 7 shall be conducted in all respects as a de novo trial on the merits, and
Indemnitee shall not be prejudiced by reason of the adverse determination under Section 6(b). 
 (c) If a determination shall
have been made pursuant to Section 6(b) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this Section 7,
absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s misstatement not materially misleading in connection with the application for indemnification, or (ii) a
prohibition of such indemnification under applicable law. 
 (d) In the event that Indemnitee, pursuant to this Section 7,
seeks a judicial adjudication of his rights under, or to recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies maintained by the Company, the Company shall pay on his
behalf, in advance, any and all expenses (of the types described in the definition of Expenses in Section 13 of this Agreement) actually and reasonably incurred by him in such judicial adjudication, regardless of whether Indemnitee
ultimately is determined to be entitled to such indemnification, advancement of expenses or insurance recovery. 
 (e) The Company shall be
precluded from asserting in any judicial proceeding commenced pursuant to this Section 7 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is
bound by all the provisions of this Agreement. The Company shall indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefore)
advance, to the extent not prohibited by law, such expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under
any directors’ and officers’ liability insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of Expenses or insurance recovery, as the
case may be. 
 (f) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under
this Agreement shall be required to be made prior to the final disposition of the Proceeding. 

  
 -8- 

 8. Non-Exclusivity; Survival of Rights; Insurance; Primacy of Indemnification;
Subrogation. 
 (a) The rights of indemnification as provided by this Agreement shall not be deemed exclusive of any other rights to
which Indemnitee may at any time be entitled under applicable law, the Amended and Restated Certificate of Incorporation, the By-laws, any agreement, a vote of stockholders, a resolution of directors or otherwise, of the Company. No amendment,
alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his Corporate Status prior to such amendment,
alteration or repeal. To the extent that a change in the DGCL, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Amended and Restated Certificate of Incorporation, By-laws and this
Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every
other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise,
shall not prevent the concurrent assertion or employment of any other right or remedy. 
 (b) To the extent that the Company maintains an
insurance policy or policies providing liability insurance for directors, officers, employees, or agents or fiduciaries of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that
such person serves at the request of the Company, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any director, officer, employee, agent or fiduciary
under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the Company shall give prompt notice of the commencement of such
Proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as
a result of such Proceeding in accordance with the terms of such policies. 
 (c) [The Company hereby acknowledges that Indemnitee has or
may have in the future certain rights to indemnification, advancement of expenses and/or insurance provided by [—] and certain of its affiliates (collectively, the “Fund Indemnitors”).
The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or
liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts
paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Amended and Restated Certificate of Incorporation or By-laws of the Company (or any other agreement between the Company and Indemnitee),
without regard to any rights Indemnitee may have against the Fund Indemnitors, and, (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution,
subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification
from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company
and Indemnitee agree that the Fund Indemnitors are express third party beneficiaries of the terms of this Section 8(c).] 
 (d)
[Except as provided in paragraph (c) above,] the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee [other than against the Fund Indemnitors], who shall execute all papers required and take
all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 

(e) [Except as provided in paragraph (c) above,] the Company shall not be liable under this Agreement to make any payment of amounts
otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 

(f) [Except as provided in paragraph (c) above,] the Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee
who is or was serving at the request of the Company as a director, 

  
 -9- 

 
officer, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount Indemnitee has actually received
as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. 

9. Exception to Right of Indemnification. Notwithstanding any provision in this Agreement, the Company shall not be obligated under
this Agreement to make any indemnity in connection with any claim made against Indemnitee: 
 (a) for which payment has actually been made
to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision, provided, that the foregoing shall not affect
the rights of Indemnitee [or the Fund Indemnitors] set forth in Section 8(c) above; 
 (b) for an accounting of profits made
from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Securities Exchange Act of 1934, as amended, or similar provisions of state statutory law or common law;

 (c) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of
any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board of Directors of the Company authorized the Proceeding (or any part of any Proceeding) prior to its
initiation or (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law; 

(d) with respect to remuneration paid to Indemnitee if it is determined by final judgment or other final adjudication that such remuneration
was in violation of law (and, in this respect, both the Company and Indemnitee have been advised that the Securities and Exchange Commission believes that indemnification for liabilities arising under the federal securities laws is against public
policy and is, therefore, unenforceable and that claims for indemnification should be submitted to appropriate courts for adjudication, as indicated in the last paragraph of this Section 9 below); 

(e) a final judgment or other final adjudication is made that Indemnitee’s conduct was in bad faith, knowingly fraudulent or
deliberately dishonest or constituted willful misconduct (but only to the extent of such specific determination); or 
 (f) on account of
conduct that is established by a final judgment as constituting a breach of Indemnitee’s duty of loyalty to the Company or resulting in any personal profit or advantage to which Indemnitee is not legally entitled. 

For purposes of this Section 9, a final judgment or other adjudication may be reached in either the underlying proceeding or
action in connection with which indemnification is sought or a separate proceeding or action to establish rights and liabilities under this Agreement.

 Any provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant
to the terms of this Agreement to indemnify Indemnitee or otherwise act in violation of any undertaking appearing in and required by the rules and regulations promulgated under the Securities Act of 1933, as amended (the “Act”), or in any
registration statement filed with the SEC under the Act. Indemnitee acknowledges that paragraph (h) of Item 512 of Regulation S-K currently generally requires the Company to undertake in connection with any registration statement filed
under the Act to submit the issue of the enforceability of Indemnitee’s rights under this Agreement in connection with any liability under the Act on public policy grounds to a court of appropriate jurisdiction and to be governed by any final
adjudication of such issue. Indemnitee specifically agrees that any such undertaking shall supersede the provisions of this Agreement and to be bound by any such undertaking. 

10. Duration of Agreement. All agreements and obligations of the Company contained herein shall continue during the period Indemnitee
is an officer or director of the Company (or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) and shall continue thereafter so
long as Indemnitee shall be subject to any Proceeding (or any proceeding commenced under Section 7 hereof) by reason of his Corporate Status, whether or not he is acting or serving in any such capacity at the time any liability or
expense is incurred for which indemnification can be provided under this Agreement. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), assigns, spouses, heirs, executors and personal and legal representatives. 

11. Security. To the extent requested by Indemnitee and approved by the Board of Directors of the Company, the Company may at any time
and from time to time provide security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line of credit, funded trust or other collateral. Any such security, once provided to Indemnitee, may not be revoked or
released without the prior written consent of the Indemnitee. 
 12. Enforcement. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumes the obligations imposed on it hereby in
order to induce Indemnitee to serve as an officer or director of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as an officer or director of the Company. 

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof. 

  
 -11- 

 13. Definitions. For purposes of this Agreement: 

(a) “Corporate Status” describes the status of a person who is or was a director, officer, employee, agent or fiduciary of
the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that such person is or was serving at the express written request of the Company. 

(b) “Disinterested Director” means a director of the Company who is not and was not a party to the Proceeding in respect of
which indemnification is sought by Indemnitee. 
 (c) “Enterprise” shall mean the Company and any other corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise that Indemnitee is or was serving at the express written request of the Company as a director, officer, employee, agent or fiduciary. 

(d) “Expenses” shall include all reasonable attorneys’ fees, retainers, court costs, transcript costs, fees of experts,
witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees and all other disbursements or expenses of the types customarily incurred in connection with prosecuting, defending,
preparing to prosecute or defend, investigating, participating, or being or preparing to be a witness in a Proceeding, or responding to, or objecting to, a request to provide discovery in any Proceeding. Expenses also shall include Expenses incurred
in connection with any appeal resulting from any Proceeding and any federal, state, local or foreign taxes imposed on the Indemnitee as a result of the actual or deemed receipt of any payments under this Agreement, including without limitation the
premium, security for, and other costs relating to any cost bond, supersede as bond, or other appeal bond or its equivalent. Expenses, however, shall not include amounts paid in settlement by Indemnitee or the amount of judgments or fines against
Indemnitee. 
 (e) “Independent Counsel” means a law firm, or a member of a law firm, that is experienced in matters of
corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect to matters concerning Indemnitee under this
Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term “Independent
Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s
rights under this Agreement. The Company agrees to pay the reasonable fees of the Independent Counsel referred to above and to fully indemnify such counsel against any and all Expenses, claims, liabilities and damages arising out of or relating to
this Agreement or its engagement pursuant hereto. 
 (f) “Proceeding” includes any threatened, pending or completed
action, suit, arbitration, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought 

  
 -12- 

 
by or in the right of the Company or otherwise and whether civil, criminal, administrative or investigative, in which Indemnitee was, is or will be involved as a party or otherwise, by reason of
the fact that Indemnitee is or was an officer or director of the Company, by reason of any action taken by him or of any inaction on his part while acting as an officer or director of the Company, or by reason of the fact that he is or was serving
at the request of the Company as a director, officer, employee, agent or fiduciary of another corporation, partnership, joint venture, trust or other Enterprise; in each case whether or not he is acting or serving in any such capacity at the time
any liability or expense is incurred for which indemnification can be provided under this Agreement; including one pending on or before the date of this Agreement, but excluding one initiated by an Indemnitee pursuant to Section 7 of
this Agreement to enforce his rights under this Agreement. 
 14. Severability. The invalidity or unenforceability of any provision
hereof shall in no way affect the validity or enforceability of any other provision. [—] Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee [—] indemnification rights to the fullest extent permitted by applicable laws. In the event any provision hereof conflicts with any applicable law, such provision shall be deemed modified, consistent with
the aforementioned intent, to the extent necessary to resolve such conflict. 
 15. Modification and Waiver. No supplement,
modification, termination or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other
provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver. 
 16. Notice By Indemnitee.
Indemnitee agrees promptly to notify the Company in writing upon being served with or otherwise receiving any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject
to indemnification covered hereunder. The failure to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise unless and only to the extent that such failure or delay
materially prejudices the Company. 
 17. Notices. All notices and other communications given or made pursuant to this Agreement
shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient, and if not so

 Subject to and with the benefit of the provisions of this lease, Landlord hereby
leases to Tenant, and Tenant leases from Landlord, the entire premises set forth on Exhibit A and described on Exhibit A including, but not limited to the buildings shown as building “A”, building “B”, building “C” and
building “D”, and including the smoke stack subject, however, to easements, reservations and restrictions of record. Tenant agrees that in the event Tenant subleases or otherwise permits any other entity to use space on the smoke stack for
communications devices, Tenant shall first obtain the approval of Landlord therefor, and any revenues received by Tenant for such use shall be shared equally with Landlord after first deducting from such revenue all third party costs and expenses,
brokerage commissions, legal fees and the like related to such use of the smoke stack. Tenant may place an antenna for Tenant’s use on the smoke stack. Tenant’s space is hereinafter referred to as “the demised premises”. The
parcel of land on which the buildings are located is sometimes hereafter referred to as “the Lot”. The Lot is represented by the area outlined by a bold line upon said Exhibit A. It is understood and agreed that said plan is intended only
to show the approximate size of the Lot as presently constituted and the approximate size and location of the buildings and for no other purpose. 

ARTICLE III 
 TERM AND CONSTRUCTION

  

	3.	(A) ORIGINAL TERM 

 To have and to hold for a period of fifteen (15) and a fraction years
(“the Term” or “the Original Term”) commencing on December 15, 2000 (being hereafter referred to as “the Commencement Date”) and, unless sooner terminated as provided herein, ending on December 31, 2015. 

 

	 	(B)	LANDLORD’S REQUIRED WORK 

 Landlord agrees to use reasonable efforts to complete
Landlord’s Required Work as described in Exhibit B, and within the time set forth therein. 
 Landlord shall permit Tenant access (at
Tenant’s sole risk) for installing equipment and furnishings in the demised premises prior to the Commencement Date if it can be done without material interference with, or delay of, Landlord’s Required Work in the demised premises and/or
in other portions of the buildings. 
  

	 	(C)	TENANT’S WORK 

 Tenant agrees that Tenant’s Work shall be in accordance with the
provisions of Exhibit C and Tenant shall diligently perform all work necessary and if required in order to cause the demised premises to not violate any applicable building, safety, fire and health codes or applicable zoning ordinance. 

  
 3 

	 	(D)	GENERAL CONSTRUCTION PROVISIONS 

 All construction work required or permitted by this lease,
whether by Landlord or by Tenant, shall be done in a good and workmanlike manner and in compliance with all applicable laws and all lawful ordinances, regulations and orders of governmental authorities and insurance rating or inspection bureaus
having jurisdiction over the buildings. Either party may inspect the work of the other at reasonable times and shall promptly give notice of observed defects. 
  

	 	(E)	CONSTRUCTION ALLOWANCE 

 As an inducement for Tenant to execute this lease and prepare the
demised premises for Tenant’s occupancy, Landlord shall pay to Tenant the sum of 197,225.00 for Tenant’s work in the office space comprising part of the demised premises; $30,000.00 for Tenant’s work on the warehouse bathrooms;
$80,000.00 for Tenant’s Work on the sprinkler system; and $70,000.00 for Tenant’s Work on the warehouse heating system. In addition, Landlord shall pay to Tenant an additional $5,000.00 in the event Tenant installs its own floor covering
in the 600 square foot lobby. So long as Tenant shall not then be in default in the performance of its agreements contained in this lease, Landlord shall pay said sums to Tenant upon the last to occur of: (a) the thirtieth (30th) day after
the Tenant’s architect certifies that Tenant’s Work has been substantially completed; and (b) the receipt by Landlord of waivers of liens from all contractors supplying labor and/or material for Tenant’s work. In the event
Landlord fails to pay said allowance to Tenant within thirty (30) days after notice from Tenant that same is past due, Tenant may offset the amount of said allowance that remains unpaid, together with interest on the unpaid sum at the Default
Rate (as defined below), from fifty percent (50%) of the monthly fixed rent thereafter payable by Tenant until paid in full. This shall be Tenant’s sole remedy for Landlord’s failure to pay said construction allowance. 

ARTICLE IV 
 LANDLORD’S
COVENANTS 
  

	4.	(A) LANDLORD’S COVENANTS DURING THE TERM: 

 Landlord covenants during the Term: 

(1) To furnish, through Landlord’s employees or independent contractors, the services listed in Exhibit D; and 

(2) Except as otherwise provided in this lease, to repair the roof and make all structural repairs to the buildings and the parking lot and
elevator as may be necessary to keep them in serviceable condition provided, however, that if any of said repairs due necessitated by Tenant’s Work or Tenant’s alterations or improvements, Tenant shall make all such repairs as may be
necessary. 
 (3) Landlord warrants that the entrances and exits to the buildings shall be in compliance with the Americans with
Disabilities Act upon the Commencement Date, and Landlord shall be responsible for maintaining said entrances and exits in compliance during the Term. Landlord represents that the Property is not in violation of applicable zoning regulations.
Landlord has received no notice of any noncompliance of the Property with Massachusetts 

  
 4 

 
General Laws, Chapter 2lE or the Department of Environmental Protection’s Massachusetts Contingency Plan and, to the best of Landlord’s knowledge, the buildings contain no asbestos or
other hazardous materials. 
 (4) Landlord will keep the buildings and other structures (including all alterations, additions, and changes
thereto to the extent made by Landlord) which are located within the Lot, insured under an all risks property insurance policy (not excluding from coverage perils normally included within the definitions of extended coverage, vandalism and malicious
mischief, earthquake and flood), in the amount of one hundred percent (100%) of the replacement value of the base buildings (excluding Tenant’s improvements), with endorsements for contingent liability from operation of building laws,
increased costs of construction, and demolition costs which may be necessary to comply with building laws. The insurance required hereby shall be written by a company authorized to do business in the state of the location of the demised premises.
Landlord will be responsible for determining the amount of property insurance to be maintained, but such coverage will be on an agreed value basis to eliminate the effects of co-insurance. Landlord will provide to Tenant a certificate from
Landlord’s insurer evidencing the coverage required under this lease, which certificate will include the waiver of subrogation. 

Landlord shall also maintain from and after the date of this lease and throughout the lease Term, commercial general liability insurance on an
occurrence basis against claims on account of bodily injury, death or property damage incurred upon any part of the demised premises. Such insurance policy will have combined single limits of not less than Two Million Dollars ($2,000,000.00) per
occurrence and provide contractual coverage of Landlord’s liability to Tenant assumed under the indemnification provision under this lease. The insurance required hereby shall be written by a company authorized to do business in the state of
the location of the demised premises. Landlord will provide to Tenant a certificate from Landlord’s insurer evidencing the coverage required under this lease. Insurance against any or all of such risks may be maintained under a blanket policy
covering the demised premises and other real estate of Landlord and/or its affiliated business organizations provided the demised premises is specifically scheduled. Said policies may contain sublimits on earthquake and flood insurance. 

The proceeds of Landlord’s property insurance in case of loss or damage will be applied on account of the obligation of Landlord to
repair and/or rebuild the damaged or destroyed buildings (but excluding Tenant’s improvements) in accordance with Article VIII of this lease provided, however, that Landlord may rebuild the buildings with a block structure, and not brick
structure. 
 Tenant agrees to pay to Landlord, as additional rent and as part of Operating Expenses, the cost to Landlord of keeping the
demised premises insured as hereinabove provided. 
  

	 	(B)	INTERRUPTIONS 

 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 (a) power losses or shortages, or (b) the necessity of Landlord’s entering the demised premises for any of the purposes in this lease authorized,
including without limitation, for repairing or altering the demised premises or any portion of the Building or for bringing materials into and/or through the demised premises in connection with the making of repairs or alterations. 

  
 5 

 In case Landlord is prevented or delayed from making any repairs, alterations or improvements or
furnishing any service or performing any other covenant or duty to be performed on Landlord’s part, by reason of any cause reasonably beyond Landlord’s control, Landlord shall not be liable to Tenant therefor, nor, except as expressly
otherwise provided in Article VIII, shall Tenant be entitled to any abatement or reduction of rent by reason thereof, 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 demised premises. Landlord reserves the right to stop any service or utility system when necessary in Landlord’s reasonable opinion by reason of accident or emergency or until necessary repairs have been completed.
Except in case of emergency repairs, Landlord will give Tenant reasonable advance notice (but in any event not less than forty eight (48) hours) of any contemplated stoppage and, in any event, Landlord will use reasonable efforts to avoid
unnecessary inconvenience to Tenant by reason thereof. 
 Notwithstanding anything in this Section (B) of Article IV to the contrary,
in the event any such disruption to Tenant’s operations and use of the demised premises is attributable to Landlord’s negligence, or that of its agents, contractors, servants or employees, or is attributable to a breach by Landlord of its
obligations under this lease, and if such disruption shall materially impair Tenant’s use of the demised premises for a period in excess of five (5) business days in duration, then a just proportion of the Rent, according to the nature and
extent of the impairment to Tenant’s operation and use of the demised premises shall abate for any such period of time from the date of disruption which is in excess of said five (5) business days in duration. 

ARTICLE V 
 RENT 

 

	5.	(A) FIXED RENT

	 	(B)	ADDITIONAL RENT - TAXES 

 (1) For the purposes of this Section, “Tax Year” shall mean
the twelve-month period in use in the City of Chelsea for the purpose of imposing ad valorem taxes upon real property. In the event that said City changes the period of its tax year, “Tax Year” shall mean a twelve-month period commencing
on the first day of such new tax year, and each twelve-month period commencing on an anniversary of such date during the Term of this lease. For purposes of this Section “the Property” shall mean the Lot and all improvements thereon from
time to time, including the buildings. For purposes of this Section the Real Estate Taxes imposed with respect to the Property shall mean the sum of: (i) the real estate taxes upon the buildings (determined in accordance with the real estate
tax bill, the assessor’s records or a certification from the assessor), plus (ii) the real estate taxes upon the Lot. Real Estate Taxes shall not include any of the following: (i) any franchise, gift, estate, inheritance, conveyance,
transfer, capital investment or other tax assessed against Landlord or Landlord’s heirs, successors or assigns; (ii) any income, excess profits or other tax, assessment, charge, or levy on the rent payable by Tenant under this lease; or
(iii) any interest, fine, or penalty for late payment or nonpayment by Landlord of any Real Estate Taxes, provided Tenant has timely paid the Real Estate Taxes. Further, as regards any assessment which under the laws then in force may be paid
in installments, there will be included within the meaning of the term “Real Estate Taxes” with respect to any fiscal year only the current annual installment. 

(2) Tenant shall not be obligated to pay Real Estate Taxes assessed with respect to the Property for any period, prior to May 1, 2001.
Commencing on May 1, 2001, and thereafter, during the Term. Tenant shall pay to Landlord, as additional rent, the Real Estate Taxes imposed with respect to the Property for each Tax Year, such amount to be apportioned on a per diem basis for
any fraction of a Tax Year during which May 1, 2001, shall occur. 
 (3) If Landlord shall receive any tax refund or rebate or sum in
lieu thereof with respect to any Tax Year after May 1, 2001, then out of any balance remaining thereof, after deducting Landlord’s reasonable expenses incurred in obtaining such refund, rebate or other sum, Landlord shall pay to Tenant,
provided that Tenant is not then in monetary default in the performance of any of its obligations hereunder, such refund or rebate, but in no event shall Landlord pay to Tenant out of such refund, rebate or other sum for any Tax Year more than the
amount paid by Tenant to Landlord pursuant to this Section (B) for such Tax Year. 
 (4) Any betterment assessment, so-called
“rent tax.” or any other tax levied or imposed by any governmental authority, in lieu of or as a substitute for Real Estate Taxes shall nevertheless be deemed to be Real Estate Taxes for the purpose of this Section (B). Furthermore, to the
extent that any equipment installed as part of the Property (e.g. heating or air conditioning equipment) shall be classified as personal property for purposes of taxation, and if such taxes are levied against Landlord or the Property, any personal
property taxes thereon shall be deemed to be Real Estate Taxes for purposes of this Section (B). 
 (5) Landlord shall, within thirty
(30) days of receiving notification thereof, send to Tenant notice of any increases in assessments for Real Estate Taxes. Provided Tenant at least thirty (30) days prior has requested Landlord to make such a contest and Landlord has not
then previously filed or does not thereafter within said thirty (30) days file a contest of the 

  
 7 

 
amount or validity of specific Real Estate Taxes which are payable by Tenant, Tenant will have the right, at Tenant’s expense, to contest the amount or validity of Real Estate Taxes by
appropriate administrative and legal proceedings brought either in Tenant’s name, Landlord’s name or jointly with Landlord, as Tenant may deem appropriate, by counsel selected and engaged by Tenant. Landlord will execute and deliver to
Tenant whatever documents may be necessary or proper to permit Tenant to contest Real Estate Taxes or which may be necessary to secure payment of any refund which may result from any such proceedings. Any refund resulting from a proceeding brought
either by Tenant or Landlord or by them jointly will be applied first to reimburse the party or parties who brought the proceedings for the costs incurred with the proceedings, and then to reimburse Tenant for the difference between the amount
Tenant paid for Real Estate Taxes for each fiscal year involved in the proceeding and the amount Tenant would have been required to pay if the Real Estate Taxes had been assessed in accordance with the decision rendered in the proceeding, together
with interest in the amount of such difference at the annual rate allowed by the court on the overpayment of Real Estate Taxes. Any remaining balance will be paid to Landlord. 

Landlord shall pay to the appropriate governmental authorities, on or before same are due, all taxes, assessments, levies or related charges
due and payable to said authorities. 
  

	 	(C)	ADDITIONAL RENT - OPERATING COSTS

the Term of this lease shall fall. 
 “Operating Expenses” shall mean all costs or expenses incurred for the operation, external

others) necessary to keep the Property in good working order, repair, appearance and condition; all costs of any reasonable insurance carried by Landlord relating to the Property and as set forth in Subsection (4) of Section (A) of Article
IV above, payments under all service contracts relating to the foregoing (provided the cost of same is reasonably competitive with other services offering a similar level of service); all compensation, fringe benefits, payroll taxes and
workmen’s compensation insurance premiums related thereto with respect to any employees of Landlord or its affiliates engaged in security and maintenance of the Property to the extent of time spent on the Property; and internal bookkeeping
professional fees and expenses; and a management fee of three percent (3%) of the Fixed Rent. Notwithstanding the foregoing, Operating Expenses shall not include the following: (i) Real Estate Taxes; (ii) cost of capital improvements
or capital repairs other than repair and repaving of the parking lot and the repair and replacement of the parking lot lighting, (iii) cost of roof repairs, unless caused by Tenant; (iv) cost of repairing design or construction defects;

 8 

 
parties; (vi) repairs or other work (including rebuilding) occasioned by casualty or condemnation; (vii) repainting of the buildings; (viii) principal or interest on debt or
amortization payments on any mortgages or deeds of trust or any other debt for borrowed money and amortization of improvements; (ix) depreciation of Landlord’s original investment in the demised premises; (x) amounts paid by Landlord
to affiliates of Landlord for services in connection with any common areas, to the extent such fees are in excess of the ordinary and reasonable fees paid in arm’s length transaction; (xi) rents and other charges payable to underlying
landlords including any charges arising due to violations of said leases; and (xii) the costs and expenses related to investigation of, testing for, removal and/or clean up of Hazardous Materials unless caused by Tenant. 

There shall not be included in such Operating Expenses brokerage fees (including rental fees) related to the operation of the buildings; interest and
depreciation charges incurred on the Property; or expenditures made by Tenant with respect to (i) cleaning, maintenance and upkeep of the demised premises. 

If during the Term of this lease, Landlord shall make any capital expenditures reasonably necessary to maintain the parking lot or the parking lot lighting,
the total amount of which is not properly included in Operating Expenses for the calendar year in which they were made, there shall nevertheless be included in Operating Expenses for each calendar year in which and after such capital expenditure is
made the annual charge-off of such capital expenditure. (Annual charge-off shall be determined by (i) dividing the original cost of the capital expenditure by the number of years of useful life thereof [the useful life shall be reasonably
determined by Landlord in accordance with generally accepted accounting principles and practices in effect at the time of acquisition of the capital item]; and (ii) adding to such quotient an interest factor computed on the unamortized balance
of such capital expenditure based upon an interest rate reasonably determined by Landlord as being the interest rate then being charged for long term mortgages by institutional lenders on like properties within the locality in which the buildings
are located). 
 Tenant’s Share of Operating Expenses: One hundred percent (100%) of the Operating Expenses. 

(2) Tenant shall not be obligated to pay the Operating Expenses for the period of time prior to May 1, 2001. Commencing on May 1,
2001 and thereafter during the Term, Tenant shall pay to Landlord, as additional rent, Tenant’s Share of Operating Expenses, such amount to be apportioned on a per diem basis for any fraction of an Operating Year during which May 1, 2001
shall occur. 
  

	 	(D)	MONTHLY PAYMENTS 

 Payment on account of the additional rent described in Sections (B) and
(C) above shall be paid monthly on the first day of each and every month included in the Term commencing, however, on May 1, 2001. Promptly after the end of each Tax Year, Landlord shall make a determination of Tenant’s share of real
estate taxes and Operating Expenses. On or before the first day of April of each calendar year (the “Statement Deadline”), Landlord will deliver a statement (the “Operating Expenses Statement”) to Tenant certified by
Landlord’s authorized representative showing: (i) the amount of the actual Operating Expenses for the preceding 

  
 9 

 
calendar year, with a breakdown of amounts by major categories of the Operating Expenses, and (ii) the amounts paid by Tenant toward the estimated Operating Expenses during the preceding
calendar year; and if the aforesaid payments theretofore made for such period by Tenant exceed Tenant’s share, such overpayment shall be credited against the payments thereafter to be made by Tenant pursuant to this Section (D); and if
Tenant’s share is greater than such payments theretofore made on account for such period, Tenant shall make a suitable payment to Landlord. The initial monthly payment on account of said additional rent shall be replaced after Landlord’s
determination of Tenant’s share for the preceding Tax Year by a payment which is one-twelfth (1/12th) of Tenant’s actual share thereof for the immediately preceding Tax Year, with adjustments as appropriate where such period is less
than a full twelve-month period. Appropriate adjustments shall be made in said monthly payment if the real estate taxes upon the Property for the current Tax Year shall be known prior to the end of said Tax Year and/or if real estate taxes shall be
payable to the taxing authority in installments, all to the end that as each payment of real estate taxes shall become payable Landlord shall have received from Tenant payments sufficient in amount to pay Tenant’s share of the building’s
Share of Real Estate Taxes then payable by Landlord. At Landlord’s election, Landlord may use its fiscal year rather than Tax Years for purposes of the adjustments described in this Section. 

 

	 	(E)	ADDITIONAL RENT - ELECTRICITY, GAS, WATER & SEWER 

 (1) The demised premises shall
have utility meters measuring the amount of the utilities consumed in the demised premises, and commencing upon the Commencement Date, Tenant shall pay to the utility companies furnishing such utilities, promptly upon the receipt of bills therefor,

any time exceed the capacity of any of the electrical conductors or equipment in or otherwise serving the demised premises. Landlord warrants that 1,200 amp electrical service is provided to the Property. 

ARTICLE VI 
 TENANT’S
COVENANTS 
  

	6.	TENANT’S COVENANTS DURING THE TERM 

 Tenant covenants during the Term and such other time
as Tenant occupies any part of the demised premises: 
 (1) To pay when due (a) all Fixed Rent and additional rent, (b) all taxes
which may be imposed on Tenant’s personal property in the demised premises (including, without limitation, Tenant’s fixtures and equipment) regardless to whomever assessed, and (c) all charges by any public utility for telephone and
other utility services rendered to the demised premises; 
 (2) Except as otherwise provided in Article VIII and Section 4(A)(2), to
keep the demised premises in good order, repair and condition, reasonable wear and tear only excepted; to replace all light bulbs as necessary; all cleaning and janitorial services for the demised premises; maintain and replace all interior glass;
keep all utilities, pipes, conduits, drains and other installations used in connection with the demised premises, including, without limitation, the 

  
 10 

 
heating, ventilating and air conditioning systems in good order, condition and repair; and at the expiration or termination of this lease peaceably to yield up the demised premises and all
changes and additions therein in such order, repair and condition, first removing all goods and effects of Tenant and those claiming under Tenant and any items the removal of which is required by any agreement between Landlord and Tenant (or
specified therein to be removed at Tenant’s election and which Tenant elects to remove), and repairing all damage caused by such removal and restoring the demised premises and leaving them clean and neat. Notwithstanding the foregoing, in the
event that Tenant proposes to make any installation, alteration, addition or improvement to the demised premises, Tenant shall give written notice to Landlord no later than fifteen (15) business days prior to the proposed date of the
commencement of construction of such installation, alteration, addition or improvement, together with plans and specifications therefor. Within ten (10) business days after the receipt by Landlord of such written notice and said plans and
specifications, Landlord shall notify Tenant in writing whether it must remove the same at the expiration or termination of the Term of this lease, and the failure of Landlord to provide such written determination to Tenant within said ten
(10) business days shall constitute Landlord’s determination that such installation, alteration, addition and/or improvement need not be removed at the expiration or termination of the Term of this lease. If Tenant elects not to request
Landlord’s consent then Tenant shall remove from the demised premises (repairing any damage caused by such removal) any such installation, alteration, addition or improvement made without Landlord’s consent and which Landlord requests
Tenant remove within thirty (30) days after the expiration or termination of the Term of this lease. Such removal shall include returning the previously modified portions of the demised premises to their condition prior to the making of such
installations, alterations, additions or improvements. Tenant’s obligations hereunder shall survive the expiration or termination of the term of this lease. For purposes of this Section (2) the word “repairs” includes the making
of replacements when necessary; 
 (3) Continuously from the Commencement Date, to use the demised premises only for the Permitted Use; and
not to injure or deface the demised premises, buildings, or Lot; nor permit any use thereof which is improper, offensive, contrary to law or ordinances, or which is liable to invalidate any insurance on the buildings (or any portion thereof) or its
contents, or liable to render necessary any addition to the buildings. Landlord acknowledges that Tenant’s use of the demised premises as a biotechnology company, including, but not limited to pharmaceutical manufacturing, will not invalidate
the insurance on the buildings; 
 (4) Intentionally Omitted; 

(5) To keep the demised premises equipped with all safety appliances required by law or ordinance or any other regulation of any public
authority and to procure all licenses and permits required because of any use made by Tenant and, if requested by Landlord, to do any work required because of such use, it being understood that the foregoing provisions shall not be construed to
broaden in any way the Permitted Use; 
 (6) Not without the prior written consent of Landlord (which consent Landlord agrees that it shall
not unreasonably withhold, delay or condition), to assign, hypothecate, pledge or otherwise encumber this lease, to make any sublease or to permit occupancy of the demised premises or any part thereof by anyone other than Tenant, voluntarily or by
operation of law, and as additional rent, to reimburse Landlord promptly upon demand for reasonable legal and other 

  
 11 

 
expenses incurred by Landlord in connection with any request by Tenant for consent to assignment or subletting. If and whenever Tenant shall not be a so-called “publicly held” company,
it is understood and agreed that the transfer of fifty percent (50%) or more of the stock in Tenant of any class (whether at one time or at intervals) shall constitute an “assignment” of Tenant’s interest in this lease. If there
shall be any assignment or subletting by Tenant pursuant to the provisions of this paragraph, Tenant and Tenant’s Guarantor shall remain primarily liable for the performance and observance of the covenants and agreements herein contained on the
part of Tenant to be performed and observed, such liability to be (in the case of any assignment) joint and several with that of such assignee. It is expressly understood and agreed that no assignment of Tenant’s interest in this lease shall be
effective until such time as Tenant shall deliver to Landlord an agreement from the assignee, which agreement shall be reasonably satisfactory to Landlord in form and substance and shall provide that the assignee agrees with Landlord to be primarily
liable for the performance and observance of the covenants and agreements herein contained on the part of Tenant to be performed and observed, such liability to be joint and several with that of Tenant. Landlord hereby agrees, however, that Tenant
may, without Landlord’s consent, assign its interest in this lease or sublet the whole or part of the demised premises to (a) an entity which owns all of the outstanding stock of Tenant (“Tenant’s Parent”); (b) an
entity wholly owned by Tenant or by Tenant’s Parent (“a Subsidiary”); (c) an entity resulting from the consolidation or merger of Tenant with any other entity; or (d) an affiliate of Tenant or Tenant’s Guarantor; 

(7) To defend Landlord, with counsel acceptable to Landlord, save Landlord harmless from, and indemnify Landlord against any liability for
injury, loss, accident or damage to any person or property and from any claims, actions, proceedings and expenses and costs in connection therewith (including, without implied limitation, reasonable counsel’s fees): (i) arising from the
omission, fault, willful act, negligence or other misconduct of Tenant or anyone claiming under Tenant, or from any use made or thing done or occurring upon or about the demised premises but not due to the omission, fault, willful act, negligence or
other misconduct of Landlord, or (ii) resulting from the failure of Tenant to perform and discharge its covenants and obligations under this lease. Landlord agrees that it will defend Tenant, with counsel acceptable to Tenant, save Tenant
harmless from, and indemnify Tenant against any liability for injury, loss, accident or damage to any person or property and from any claims, actions, proceedings and expenses and costs in connection therewith (including, without implied limitation,
reasonable counsel’s fees): (i) arising from the omission, fault, willful act, negligence or other misconduct of Landlord or anyone claiming under Landlord, or from any use made or thing done or occurring upon or about the demised premises
but not due to the omission, fault, willful act, negligence or other misconduct of Tenant, or (ii) resulting from the failure of Landlord to perform and discharge its covenants and obligations under this lease, or (iii) arising from any
hazardous material placed on the demised premises by Landlord or its agents or employees, or existing prior to Tenant’s occupancy of the demised premises. Landlord shall be responsible for remediating such hazardous material if required by law.

 (8) To maintain public liability insurance upon the demised premises in amounts which shall, at the beginning of the Term, be at least
equal to $5,000,000.00 for bodily injury or death to one or more individuals and $2,000,000.00 for damage to property, and from time to time during the Term, shall be for such higher limits, if any, as are customarily carried in the area in which
the demised premises are located upon property similar in type and use to the demised 

  
 12 

 
premises. Such insurance shall name Landlord, Landlord’s Managing Agent, and Landlord’s Mortgagee as additional insureds. Tenant shall deliver to Landlord the policies of such
insurance, or certificates thereof, not more than fifteen (15) days following the Commencement Date, and each renewal policy or certificate thereof, not more than fifteen (15) days following the expiration of the policy it renews. Each
such policy shall be written by a responsible insurance company authorized to do business in the Commonwealth of Massachusetts and shall provide that the same shall not be modified or terminated without at least twenty (20) days’ prior
written notice to each named insured; 
 (9) To keep all employees working in the demised premises covered by workmen’s compensation
insurance in amounts required by law; 
 (10) To permit Landlord and its agents entry: to examine the demised premises at reasonable times
and, if Landlord shall so elect, to make repairs, alterations and replacements; to remove, at Tenant’s expense, any changes, additions, signs, curtains, blinds, shades, awnings, aerials, flagpoles, or the like not consented to in writing; and
to show the demised premises to prospective tenants during the twelve months preceding the expiration of the Term and to prospective purchasers and mortgagees at all reasonable times. Tenant shall be allowed exclusive building mounted signage. Such
signage shall be provided at Tenant’s expense, subject to all applicable building codes and zoning by-laws. Further, subject to the receipt by Tenant of all necessary approvals (if any are so required), from the City of Chelsea, Tenant shall
have the right to install communications devices on the roof of building A and/or building B. The size, location and method of attachment shall be subject to Landlord’s prior review and approval and shall be in compliance with all state and
local building codes and other applicable zoning restrictions. All costs associated with the installation, maintenance and removal of such rooftop installations shall be the sole responsibility of Tenant. Tenant shall in no event void
Landlord’s roof warranties and guaranties; 
 (11) Not to place a load upon any part of the floor of the demised premises exceeding
that for which said floor was designed or in violation of what is allowed by law. Tenant’s business machines and mechanical equipment which cause vibration or noise that may be transmitted to the building structure or to any other space in the
buildings shall be placed and maintained by Tenant so as not to cause structural damage to the buildings; 
 (12) All the furnishings,
fixtures, equipment, effects and property of every kind, nature and description of Tenant and of all persons claiming by, through or under Tenant which, during the continuance of this lease or any occupancy of the demised premises by Tenant or
anyone claiming under Tenant, may be on the demised premises or elsewhere in the buildings or on the Lot shall be at the sole risk and hazard of Tenant, and if the whole or any part thereof shall be destroyed or damaged by fire, water or otherwise,
or by the leakage or bursting of water pipes, steam pipes, or other pipes, by theft, or from any other cause, no part of said loss or damage is to be charged to or to be borne by Landlord, unless caused by the negligence or willful act of Landlord
or its agents, servants, contractors or employees; 
 (13) To pay promptly when due the entire cost of any work done on the demised premises
by Tenant and those claiming under Tenant; not to cause or permit any liens for labor or materials performed or furnished in connection therewith to attach to the demised premises; and immediately to discharge any such liens which may so attach;

  
 13 

 (14) Intentionally Omitted; 

(15) To pay to Landlord one and one half
(1 1⁄2) times the total of the Fixed Rent and additional rent then applicable for each month or portion thereof that Tenant shall retain possession of the
demised premises or any part thereof after the termination of this lease, whether by lapse of time or otherwise; however, the provisions of this subsection shall not operate as a waiver by Landlord of any right of re-entry provided in this lease or
as a matter of law; 
 (16) To insure the contents, equipment, and improvements of Tenant and those claiming under Tenant, under policies
covering at least fire and the standard extended coverage risks, in amounts equal to the replacement cost thereof, the terms of which policies shall provide that such insurance shall not be canceled without at least twenty (20) days’ prior
written notice to Landlord. Copies of such insurance policy or policies, or certificates thereof, shall be delivered to Landlord not more than fifteen (15) days following the Commencement Date and each renewal policy or certificate thereof, not
more than fifteen (15) days following the expiration of the policy it renews; and 
 (17) To pay Landlord’s expenses, including
reasonable attorney’s fees, incurred in enforcing any obligation of Tenant in this lease. Landlord agrees that it shall pay Tenant’s expenses including reasonable attorney’s fees incurred in enforcing any obligation of Landlord in
this lease. 
 ARTICLE VII 

DEFAULT 
  

	7.	(A) EVENTS OF DEFAULT 

 (1) If Tenant shall default in the payment of Fixed Rent, additional
rent or other payments required of Tenant, and if Tenant shall fail to cure said default within ten (10) days after receipt of notice of said default from Landlord, or (2) if Tenant shall default in the performance or observance of any
other agreement or condition on its part to be performed or observed and if Tenant shall fail to cure said default within thirty (30) days after receipt of notice of said default from Landlord (but if longer than thirty (30) days shall be
reasonably required to cure said default, then if Tenant shall fail to commence the curing of such default within thirty (30) days after receipt of said notice and diligently prosecute the curing thereof to completion), or (3) if any
person shall levy upon, or take this leasehold interest or any part thereof upon execution, attachment or other process of law, or (4) if Tenant or Guarantor shall make an assignment of its property for the benefit of creditors, or (5) if
Tenant or Guarantor shall be declared bankrupt or insolvent according to law, or (6) if any bankruptcy or insolvency proceedings shall be commenced by or against Tenant or Guarantor, or (7) if a receiver, trustee or assignee shall be
appointed for the whole or any part of Tenant’s or Guarantor’s property, then in any of said cases, Landlord lawfully may immediately, or at any time thereafter, and without any further notice or demand except as is set forth herein and as
required by law, enter into and 

  
 14 

 
upon the demised premises or any part thereof in the name of the whole, and hold the demised premises as if this lease had not been made, and expel Tenant and those claiming under it and remove
its or their property without being taken or deemed to be guilty of any manner of trespass (or Landlord may send written notice to Tenant of the termination of this lease), and upon entry as aforesaid (or in the event that Landlord shall send Tenant
notice of termination as above provided, on the fifth day next following the date of the sending of the notice), the term of this lease shall terminate. Notwithstanding the provisions of clause (1) of the immediately preceding sentence, if
Landlord shall have rightfully given Tenant notice of default pursuant to said clauses twice during any twelve (12) month period, and if Tenant shall thereafter in such twelve (12) month period default in the payment of Fixed Rent,
additional rent or other payments required of Tenant, then Landlord may exercise the right of termination provided for it in said immediately preceding sentence without first giving Tenant notice of such default and the opportunity to cure the same
within the time provided in said clause (1). Tenant hereby expressly waives any and all rights of redemption granted by or under any present or future laws in the event of Tenant being evicted or dispossessed for any cause, or in the event Landlord
terminates this lease as provided in this Article. 
  

	 	(B)	OBLIGATIONS THEREAFTER 

 In case of any such termination, Tenant will indemnify Landlord each
month against all loss of Fixed Rent and additional rent and against all obligations which Landlord may incur by reason of any such termination between the time of termination and the expiration of the Term. It is understood and agreed that at the
time of the termination or at any time thereafter Landlord may rent the demised premises, and for a term which may expire before or after the expiration of the Term, without releasing Tenant from any liability whatsoever, that Tenant shall be liable
for any expenses incurred by Landlord in connection with obtaining possession of the demised premises, with removing from the demised premises property of Tenant and persons claiming under it (including warehouse charges), with putting the demised
premises into good condition for reletting, and with any reletting, including, but without limitation, reasonable attorneys’ fees and brokers fees, and that any monies collected from any reletting shall be applied first to the foregoing
expenses and then to the payment of Fixed Rent, additional rent and all other payments due from Tenant to Landlord. 
 ARTICLE VIII 

CASUALTY AND TAKING 
  

	8.	(A) CASUALTY AND TAKING 

 In case during the Term all or any substantial part of the demised
premises, the buildings, or Lot or any one or more of them, are damaged by fire or any other casualty or by action of public or other authority or are taken by eminent domain, this lease shall terminate at Landlord’s election, which may be made
notwithstanding Landlord’s entire interest may have been divested, by notice given to Tenant within thirty (30) days after the occurrence of the event giving rise to the election to terminate. Said notice shall, in the case of damage as
aforesaid, specify the effective date of termination which shall be not less than thirty nor more than sixty days after the date of notice of such termination. In the case of any such taking by eminent domain, the effective date of the termination
shall be the day on which the taking authority shall take 

  
 15 

 
possession of the taken property. Fixed Rent and additional rent shall be apportioned and adjusted as of the effective date of any such termination. If in any such case the demised premises are
rendered unfit for use and occupation and this lease is not so terminated, Landlord shall use due diligence to put the demised premises, or, in the case of a taking, what may remain thereof (excluding any items which Tenant may be required or
permitted to remove, from the demised premises at the expiration of the Term) into proper condition for use and occupation, but Landlord shall not be required to spend more than the net proceeds of insurance or award of damages it receives therefor,
and a just proportion of the Fixed Rent and additional rent according to the nature and extent of the injury to the demised premises shall be abated until the demised premises or such remainder shall have been put by Landlord in such condition; and
in case of a taking which permanently reduces the area of the demised premises, a just proportion of the Fixed Rent shall be abated for the remainder of the Term. Notwithstanding the foregoing, in the event that there is a fire or other casualty or
a taking by eminent domain or by action of public or other authority, Landlord shall, within thirty (30) days of such event, make a good faith estimate of the anticipated restoration time. If pursuant to such estimate the damage to the base
buildings or the Lot cannot be repaired and restored to substantially the same dimensions as prior to the casualty and as reasonably required for Tenant to conduct its business within eighteen (I8) months from the occurrence of the same, Tenant
shall have the right to terminate this lease by notice to this effect given to Landlord within thirty (30) days after receipt of Landlord’s determination as aforesaid, and which termination shall be effective on the tenth (10th) day
following the receipt by Landlord of said termination notice. If this lease shall not be terminated, as aforesaid, Landlord shall promptly commence to rebuild same provided, however, that if the buildings or Lot are not so restored within said
eighteen (18) months, then Tenant shall have the right, as Tenant’s sole remedy, to terminate this lease at any time thereafter but prior to the completion of the restoration. Further, if any such fire or other casualty or taking by
eminent domain or by action of public or other authority occurs during the last two (2) years of the Term of this lease, and the demised premises are damaged or destroyed as a result thereof to the extent of fifteen percent (15%) or more
of its insurable value, or if the square foot floor area of the demised premises are reduced by such taking during the last two (2) years of the Term by more than fifteen percent (15%), then Landlord and Tenant shall have the right to terminate
this lease, by written notice given to the other party within thirty (30) days after the casualty or taking, and which termination shall, be effective on the tenth (10th) day following the delivery of said termination notice. 

 

	 	(B)	RESERVATION OF AWARD 

 Landlord reserves to itself any and all rights to receive awards made
for damage to the demised premises, buildings or Lot and the leasehold hereby created, or any one or more of them, accruing by reason of any exercise of the right of eminent domain or by reason of anything done in pursuance of public or other
authority. Tenant hereby releases and assigns to Landlord all of Tenant’s rights to such awards, and covenants to deliver such further assignments and assurances thereof as Landlord may from time to time request. It is agreed and understood,
however, that Landlord does not reserve to itself, and Tenant does not assign to Landlord, any damages payable for (i) movable equipment, trade fixtures, leasehold improvements, alterations and additions made by Tenant at Tenant’s sole
cost and expense, and personal property installed by Tenant or anybody claiming under Tenant at its own expense or (ii) relocation expenses, but in each case only if and to the extent that such damages are recoverable by Tenant from such
authority in a separate action and without reducing Landlord’s award of damages.

 ARTICLE IX 

MORTGAGEE 
  

	9.	(A) SUBORDINATION TO MORTGAGES 

 It is agreed that the rights and interest of Tenant under this
lease shall be: (i) subject and subordinate to the lien of any present or future first mortgage and to any and all advances to be made thereunder, and to the interest thereon, upon the demised premises or any property of which the demised
premises are a part, if the holder of such mortgage shall elect, by notice to Tenant, to subject and subordinate the rights and interest of Tenant under this lease to the lien of its mortgage; or (ii) prior to the lien of any present or future
first mortgage, if the holder of such mortgage shall elect, by notice to Tenant, to give the rights and interest of Tenant under this lease priority to the lien of its mortgage. In the event of any of such elections, and upon notification by the
holder of such mortgage to that effect, the rights and interest of Tenant under this lease shall be deemed to be subordinate to, or to have priority over, as the case may be, the lien of said mortgage, irrespective of the time of execution or time
of recording of any such mortgage. Tenant agrees that it will, upon request of Landlord, execute, acknowledge and deliver any and all reasonable instruments deemed by Landlord necessary or desirable to evidence or to give notice of such
subordination or priority and reasonably acceptable to Tenant. The word “mortgage” as used herein includes mortgages, deeds of trust or other similar instruments and modifications, consolidations, extensions, renewals, replacements and
substitutes thereof. Whether the lien of any mortgage upon the demised premises or any property of which the demised premises are a part shall be superior or subordinate to this lease and the lien hereof, Tenant agrees that it will, upon request,
attorn to the holder of such mortgage or anyone claiming under such holder and their respective successors and assigns in the event of foreclosure of or similar action taken under such mortgage. Tenant further agrees that it shall not subordinate
its interest in this lease to the lien of any junior mortgage, security agreement or lease affecting the demised premises, unless the holder of the first mortgage upon the demised premises or property which includes the demised premises shall
consent thereto. Notwithstanding anything to the contrary contained in this Article 9, Tenant shall not be required to subordinate this lease and the lien hereof to the lien of any mortgage unless the holder of such mortgage shall enter into an
agreement with Tenant, in a form reasonably acceptable to Tenant, recordable in form, to the effect that in the event of foreclosure of, or similar action taken under, such mortgage, all of the terms and conditions of this lease shall remain in
effect and Tenant’s possession of the demised premises shall not be terminated or disturbed by such mortgage holder or anyone claiming under such mortgage holder so long as Tenant shall not be in default under this lease beyond any applicable
cure period. Landlord shall obtain such an agreement from the present mortgagee of the Property. 
  

	 	(B)	LIMITATION ON MORTGAGEE’S LIABILITY 

 Upon entry and taking possession of the mortgaged
premises for any purpose, the holder of a mortgage shall have all rights of Landlord, and during the period of such possession Landlord, not such mortgage holder, shall have the duty to perform all of Landlord’s obligations

  
 17 

 
hereunder. No such holder shall be liable, either as a mortgagee or as holder of a collateral assignment of this lease, to perform, or be liable in damages for failure to perform, any of the
obligations of Landlord unless and until such holder shall succeed to Landlord’s interest herein through foreclosure of its mortgage or the taking of a deed in lieu of foreclosure, and thereafter such mortgage holder shall not be liable for the
performance of any of Landlord’s obligations hereunder, except for the performance of those obligations which arise during the period of time that such mortgage holder holds Landlord’s right, title and interest in this lease or which arose
prior thereto and are of a continuing nature, such liability to be limited to the same extent as Landlord’s liability is limited pursuant to Section 10(E) hereof. 
  

	 	(C)	NO RELEASE OR TERMINATION 

 No act or failure to act on the part of Landlord which would
entitle Tenant under the terms of this lease, or by law, to be relieved of any of Tenant’s obligations hereunder or to terminate this lease, shall result in a release or termination of such obligations or a termination of this lease unless
(i) Tenant shall have first given written notice of Landlord’s act or failure to act to Landlord’s mortgagees of record, provided Tenant has received written notice of such mortgagee, if any, specifying the act or failure to act on
the part of Landlord which could or would be the basis of Tenant’s rights and (ii) such mortgagees, after receipt of such notice, have failed or refused to correct or cure the condition complained of within the same time thereafter as
allowed by Landlord, but nothing contained in this Section (C) shall be deemed to impose any obligation on any such mortgagee to correct or cure any such condition. Finally, Tenant agrees that so long as any present or future mortgage shall
remain in effect Tenant shall not alter, modify, amend, change, surrender or cancel this lease nor pay the rent due hereunder in advance for more than thirty (30) days, except as may be required herein, without the prior written consent of the
holder thereof, and Tenant will not seek to be made an adverse or defendant party in any action or proceeding brought to enforce or foreclose such mortgage. 

ARTICLE X 
 GENERAL PROVISIONS 

 

	10.	(A) CAPTIONS 

 The captions of the Articles are for convenience and are not to be considered in
construing this lease. 
  

	 	(B)	SHORT FORM LEASE 

 Upon request of either party both parties shall execute and deliver a short
form of this lease in form appropriate for recording, and if this lease is terminated before the Term expires, an instrument in such form acknowledging the date of termination. No such short form lease shall contain any indication of the amount of
the rentals payable hereunder by Tenant. 
  

	 	(C)	RELOCATION 

 Intentionally Omitted. 

  
 18 

	 	(D)	NOTICES 

 All notices and other communications authorized or required hereunder shall be in
writing and shall be given by mailing the same by certified or registered mail, return receipt requested, postage prepaid, by mailing the same by Express Mail or by having the same delivered by a commercial delivery service such as Federal Express,
UPS, Purolator Courier and the like. If given to Tenant the same shall be directed to Tenant at 64 Sidney Street, Cambridge, Massachusetts 42139, Attention: Chief Financial Officer, or to such other person or at such other address as Tenant may
hereafter designate by notice to Landlord; and if given to Landlord the same shall be directed to Landlord at Landlord’s Address, or to such other person or at such other address as Landlord may hereafter designate by notice to Tenant. In the
event the notice directed as above provided shall not be received upon attempted delivery thereof to the proper address and shall be returned by the Postal Service or delivery service to the sender because of a refusal of receipt, the absence of a
person to receive, or otherwise, the time of the giving of such notice shall be the first business day on which delivery was so attempted. 

After receiving notice from Landlord or from any person, firm or other entity that such person, firm or other entity holds a mortgage which
includes the demised premises as part of the mortgaged premises, no notice from Tenant to Landlord shall be effective unless and until a copy of the same is given by certified or registered mail to such holder, and the curing of any of
Landlord’s defaults by such holder shall be treated as performance by Landlord, it being understood and agreed that such holder shall be afforded the same period of time after the receipt of such notice as Landlord has in which to effect such
cure. 
  

	 	(E)	SUCCESSORS AND ASSIGNS 

 The obligations of this lease shall run with the land, and this lease
shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, legal representatives, successors and assigns, except that the Landlord named herein and each successive owner of Landlord’s interest in this lease
shall be liable only for the obligations of Landlord accruing during the period of its ownership. Whenever Landlord’s interest in this lease is owned by a trustee or trustees, the obligations of Landlord shall be binding upon Landlord’s
trust estate, but not upon any trustee, beneficiary or shareholder of the trust individually. Without limiting the generality of the foregoing, and whether or not Landlord’s interest in this lease is owned by a trustee or trustees, Tenant
specifically agrees to look solely to Landlord’s interest in the buildings and Lot (including any consideration received as part of a transfer of the Property and insurance proceeds and condemnation awards) for recovery of any judgment from
Landlord, it being specifically agreed that neither Landlord, any trustee, beneficiary or shareholder of any trust estate for which Landlord acts nor any person or entity claiming by, through or under Landlord shall ever otherwise be personally
liable for any such judgment. The foregoing shall not limit any injunctive relief to which Tenant may be entitled. 
  

	 	(F)	NO SURRENDER 

 The delivery of keys to any employee of Landlord or to Landlord’s agent or
any employee thereof shall not operate as a termination of this lease or a surrender of the demised premises. 

  
 19 

	 	(G)	WAIVERS AND REMEDIES 

 The failure of Landlord or of Tenant to seek redress for violation of,
or to insist upon the strict performance of any covenant or condition of this lease shall not be deemed a waiver of such violation nor prevent a subsequent act, which would have originally constituted a violation, from having all the force and
effect of an original violation. The receipt by Landlord of Fixed Rent or additional rent with knowledge of the breach of any covenant of this lease shall not be deemed a waiver of such breach by Landlord unless such waiver be in writing signed by
Landlord. No consent or waiver express or implied, by Landlord or Tenant to or of any breach of any agreement or duty shall be construed as a waiver or consent to or of any other breach of the same or any other agreement or duty. No acceptance by
Landlord of a lesser sum than the Fixed Rent and additional rent then due shall be deemed to be other than on account of the earliest installment of such rent due nor shall acceptance by Tenant of any lesser sum that may be due Tenant from Landlord
be deemed to be other than on account of the full amount due, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as rent be deemed as accord and satisfaction, and Landlord or Tenant, may accept such
check or payment without prejudice to Landlord’s or Tenant’s right to recover the balance of such installment or pursue any other remedy available to it. The specific remedies to which Landlord or 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 to which it may be lawfully entitled in case of any breach or threatened breach by Tenant or Landlord of any provisions of this lease. In addition to
the other remedies provided in this lease, Landlord and Tenant 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 a decree
compelling specific performance of any such covenants, conditions or provisions. If any term of this lease, or the application thereof to any person or circumstances shall be held, to any extent, to be invalid or unenforceable, the remainder of this
lease, or the application of such term to persons or circumstances other than those as to which it has been held invalid or unenforceable, shall not be affected thereby, and each term of this lease shall be valid and enforceable to the fullest
extent permitted by law. If any interest to be paid by Tenant hereunder shall exceed the highest lawful rate which Landlord may recover from Tenant, such interest shall be reduced to such highest lawful rate of interest. 

 

	 	(H)	SELF-HELP 

 If Tenant shall at any time default in the performance of any obligation under this
lease, Landlord shall have the right, but shall not be obligated, to enter upon the demised premises and to perform such obligation, notwithstanding the fact that no specific provision for such performance by Landlord is made in this lease with
respect to such default. In performing such obligation, Landlord may make any payment of money or perform any other act. All sums so paid by Landlord (together with interest, from the time paid by Landlord until the time Tenant repays the same to
Landlord at the Default Rate set forth in Section (A) of Article V above), shall be deemed to be additional rent and shall be payable to Landlord immediately on demand. Landlord may exercise the foregoing right without waiving any other of
its rights or releasing Tenant from any of its obligations under this lease. If Landlord shall at any time default in the performance of any obligation under this lease, Tenant shall have the right, but shall not be obligated, to enter upon the
demised premises and to perform such obligation, notwithstanding 

  
 20 

 
the fact that no specific provision for such performance by Tenant is made in this lease with respect to such default. In performing such obligation, Tenant may make any payment of money or
perform any other act. All sums so paid by Tenant (together with interest, from the time paid by Tenant until the time Landlord repays the same to Tenant, Default Rate set forth in Section (A) of Article V above), shall be payable to
Tenant immediately on demand. Tenant may exercise the foregoing right without waiving any other of its rights or releasing Landlord from any of its obligations under this lease. If Landlord shall not reimburse Tenant within thirty (30) days of
Tenant’s demand, Tenant may set off such sums from fifty percent (50%) of the monthly Fixed Rent payable by Tenant thereafter. 
  

	 	(I)	ESTOPPEL CERTIFICATE 

 Tenant agrees from time to time after the Commencement Date, upon not
less than ten (10) business days’ prior written request by Landlord, to execute, acknowledge and deliver to Landlord a statement in writing certifying that this lease is unmodified and in full force and effect; that Landlord has completed
Landlord’s Required Work; that Tenant has no defenses, offsets or counterclaims against its obligations to pay the Fixed Rent and additional rent and to perform its other covenants under this lease; that there are no uncured defaults of
Landlord or Tenant under this lease (or, if there have been any modifications, that this lease is in full force and effect as modified and stating the modifications, and, if there are any defenses, offsets, counterclaims, or defaults, setting them
forth in reasonable detail); and the dates to which the Fixed Rent, additional rent and other charges have been paid. Any such statement delivered pursuant to this Section (I) may be relied upon by any prospective purchaser or mortgagee of
premises which include the demised premises or any prospective assignee of any such mortgagee. Landlord shall upon not less than ten (10) business days prior written request of Tenant deliver to Tenant a similar statement as requested herein.

  

	 	(J)	WAIVER OF SUBROGATION 

 (1) Tenant hereby releases Landlord to the extent of Tenant’s
insurance coverage, and to the full extent in the event Tenant elects to self insure for Tenant’s personal property as permitted herein, from any and all liability for any loss or damage caused by fire or any of the extended coverage casualties
or any other casualty insured against, even if such fire or other casualty shall be brought about by the fault or negligence of Landlord or its agents. 

(2) Landlord hereby releases Tenant, to the extent of the Landlord’s insurance coverage and to the extent required to be carried pursuant
to this lease, from any and all liability for any loss or damage caused by fire or any of the extended coverage casualties or any other casualty insured against, even if such fire or other casualty shall be brought about by the fault or negligence
of Tenant or its agents. 
  

	 	(K)	BROKERS 

 Tenant hereby represents and warrants to Landlord that it has dealt with no broker in
connection with this lease other than Burgess Properties, Inc., and Meredith & Grew (“the Listed Brokers”), and there are no other brokerage commissions or other finders’ fees payable in connection herewith. Tenant hereby
agrees to hold Landlord harmless from, and indemnified 

  
 21 

 
against, all loss or damage (including without limitation, the cost of defending the same) arising from any claim by any broker other than the Listed Brokers, claiming to have dealt with Tenant.
Landlord shall pay the brokerage commission due the Listed Brokers by separate agreement, Landlord hereby represents and warrants to Tenant that it has dealt with no broker in connection, with this lease other than Burgess Properties, Inc., and
Meredith & Grew (“the Listed Brokers”), and there are no other brokerage commissions or other finders’ fees payable in connection herewith. Landlord hereby agrees to hold Tenant harmless from and indemnified against, all loss
or damage (including without limitation, the cost of defending the same) arising from any claim by any broker other than the Listed Brokers, claiming to have dealt with Landlord. 

 

	 	(L)	LANDLORD’S DEFAULTS 

 Landlord shall not be deemed to have committed a breach of any
obligation to make repairs or alterations or perform any other act unless: (1) it shall have made such repairs or alterations or performed such other act negligently; or (2) it shall have received notice from Tenant designating the
particular repairs or alterations needed or the other act of which there has been failure of performance and shall have failed to make such repairs or alterations or performed such other act within a thirty (30) days after the receipt of such
notice (provided, however that if it shall reasonably require longer than thirty (30) days, then such longer period provided Landlord commences such curing within said thirty (30) days and prosecutes same to completion with due diligence);
and in the latter event Landlord’s liability shall be limited to the cost of making such repairs or alterations or performing such other act. Tenant may, following such thirty (30) day (or longer) period make such repairs or perform such
act and Tenant may set off the costs thereof from fifty percent (50%) of the monthly Fixed Rent payable by Tenant thereafter. The foregoing shall not limit any injunctive relief to which Tenant may be entitled. 

 

	 	(M)	EFFECTIVENESS OF LEASE 

 The submission of this lease for examination does not constitute a
reservation of, or option for, the demised premises, and this lease becomes effective as a lease only upon execution and unconditional delivery thereof by both Landlord and Tenant. 

 

	 	(N)	HAZARDOUS MATERIALS 

 Tenant shall not (either with or without negligence) cause or permit the
escape, disposal or release of any biologically or chemically active or other hazardous substances, or materials. Tenant shall not allow the storage or use of such substances or materials in any manner not sanctioned by the applicable permits, or by
law or by the highest standards prevailing in the industry for the storage and use of such substances or materials, nor allow to be brought into the Lot any such materials or substances except to use in the ordinary course of Tenant’s business,
and then only after written notice is given to Landlord of the identity of such substances or materials. Tenant shall obtain and maintain all proper permits required by applicable law or ordinance for the storage and use of hazardous materials, and
Tenant shall furnish evidence of same upon request. Without limitation, hazardous substances and materials shall include those described in the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, 42 U.S.C.
Section 9601 et seq., the Resource Conservation and Recovery Act, as amended, 42 U.S.C. Section 6901 at seq., any applicable state or local laws and the 

  
 22 

 
regulations adopted under these acts. If any lender or governmental agency shall ever require testing to ascertain whether or not there has been any release of hazardous materials, and if it is
determined that there has been a release of hazardous materials attributable to Tenant, then the reasonable costs thereof shall be reimbursed by Tenant to Landlord upon demand as additional rent. In addition, Tenant shall execute affidavits,
representations and the like from time to time at Landlord’s request concerning Tenant’s best knowledge and belief regarding the presence of hazardous substances or materials on the demised premises. In all events, Tenant shall indemnify
Landlord in the manner elsewhere provided in this lease from any release of hazardous materials on the demised premises occurring while Tenant is in possession or elsewhere if caused by Tenant or persons acting under Tenant. The within covenants
shall survive the expiration or earlier termination of the Term of this lease. Landlord acknowledges that Tenant may use and store certain hazardous materials provided Tenant uses, stores and removes same in accordance with all applicable laws.
Tenant shall in all events remove any such hazardous materials upon the expiration of the Term of this lease. Landlord shall have the right, at reasonable times and upon prior reasonable notice (but in any event not less than 48 hours prior notice),
to inspect the demised premises to determine the use, storage and removal of such hazardous materials. Upon request, Tenant shall give Landlord a list of the hazardous materials used, stored and removed from the demised premises. Notwithstanding any
provision of this lease to the contrary, Landlord shall solely be responsible for the remediation (or to cause such removal or remediation) and all costs thereof to the extent required by and in compliance with all legal requirements of any
hazardous material present in, on or under the demised premises existing prior to the date Landlord delivers the demised premises to Tenant, whether now known or discovered hereafter, or to the extent caused by Landlord, or its servants or agents.
Landlord shall indemnify and hold Tenant harmless from any claims, damages, liabilities, penalties, fines and costs arising directly out of any condition caused or created by Landlord’s failure to comply with its obligations under this Section.
The foregoing indemnification of Tenant by Landlord includes, without limitation, all costs incurred by or imposed upon Tenant in connection with any judgments, damages, penalties, fines, liabilities or losses (including, without limitation, sums
paid in settlement of claims, reasonable attorneys’ fees, consultant fees and expert fees). Landlord’s obligations under this Section will survive the termination or early expiration of this lease. 

 

	 	(O)	DELAYS 

 In any case where either party hereto is required to do any act (other than make a
payment of money), delays caused by or resulting from Act of God, war, civil commotion, fire or other casualty, labor difficulties, shortages of labor, materials or equipment, government regulations or other causes beyond such party’s
reasonable control (other than such party’s financial condition) shall not be counted in determining the time during which such act shall be completed, whether such time, be designated by a fixed date, a fixed time or “a reasonable
time”.

 ARTICLE XIII 

OPTION 
  

	13.	(A) OPTION TERM 

 Tenant shall have the right, at its election, to extend the Original Term of
this lease for an additional period of five (5) years commencing upon the expiration of the Original Term, provided that Landlord shall receive written notice from Tenant of the exercise of its election at least nine (9) months prior to
the expiration of the Original Term and provided further that Tenant shall not be in default beyond any applicable cure period at the time of Landlord’s receipt of such notice in the payment of any Fixed Rent due Landlord by Tenant. Tenant
shall have the right, at its election, to further extend the Original Term as previously extended for one (1) additional period of five (5) years commencing upon the expiration of the Original Term as previously extended, provided that
Landlord shall receive written notice from Tenant of the exercise of its election at least nine (9) months prior to the expiration of the Original Term as previously extended and provided further that Tenant shall not be in default beyond any
applicable cure period at the time of Landlord’s receipt of such notice in the payment of any Fixed Rent due Landlord by Tenant. The expression “the original term” means the period of fifteen (15) years referred to in Section
(A) of Article 1 of this lease. Prior to the exercise by Tenant of either of said elections to extend the Original Term, the expression “the term of this lease” or any equivalent expression shall mean the Original Term; after the
exercise by Tenant of one or both of the aforesaid elections, the expression “the term of this lease” or any equivalent expression shall mean the Original Term as it may have been then extended. Except as expressly otherwise provided in
this lease, all the agreements and conditions in this lease contained shall apply to the additional period or periods to which the Original Term shall be extended as aforesaid. If Landlord shall receive notice of the exercise of an election in the
manner and within the time provided aforesaid, the Term shall be extended upon the receipt of the notice without the requirement of any action on the part of Landlord. 
  

	 	(B)	OPTION RENT 

 During each of the additional periods for which the Original Term of this lease
may be extended as set forth in Section (A) of this Article XIII above, the Fixed Rent payable hereunder shall be adjusted so as to equal the greater of (a) the Fixed Rent payable immediately prior thereto, or (b) the “fair
market rent”, as mutually determined by Landlord and Tenant through the process of negotiation. Notwithstanding anything to the contrary contained herein, however, if for any reason whatsoever Landlord and Tenant shall not agree in writing upon
the “fair market rent” for the additional period in question at least six (6) months prior to the expiration of the 

  
 24 

 
Original Term, or the first additional period, as the case may be, then the fair market rent for premises of the size and nature of the demised premises shall be determined by licensed real
estate appraisers having at least ten (10) years’ experience in the appraisal of commercial real estate in Greater Boston, Massachusetts, one such appraiser to be designated by each of Landlord and Tenant. If either party shall fail to
designate its appraiser by giving notice of the name of such appraiser to the other party within fifteen (15) days after receiving notice of the name of the other party’s appraiser, then the appraiser chosen by the other party shall
determine the fair market rent and his determination shall be final and conclusive. If the appraisers designated by Landlord and Tenant shall disagree as to the fair market rent, but if the difference between their estimates of fair market rent
shall be five percent (5%) or less of the greater of the estimates, then the average of their estimates shall be the fair market rent for purposes hereof. If the appraisers designated by Landlord and Tenant shall disagree as to the amount of
fair market rent, and if their estimates of fair market rent shall vary by more than five percent (5%) of the greater of said estimates, then they shall jointly select a third appraiser meeting the qualifications set forth above, and his
estimate of fair market rent shall be the fair market rent for purposes hereof if it is not greater than the greater of the other two estimates and not less than the lesser of the other two estimates. If said third appraiser’s estimate is
greater than the greater of the other two estimates, then the greater of the other two estimates shall be the fair market rent for purposes hereof; and if the estimate of the third appraiser shall be less than the lesser of the other two estimates,
then the lesser of the other two estimates shall be the fair market rent for purposes hereof. Each of Landlord and Tenant shall pay for the services of its appraiser, and if a third appraiser shall be chosen, then each of Landlord and Tenant shall
pay for one-half of the services of the third appraiser. In determining fair market rent, any improvements made by Tenant in the demised premises and not otherwise reimbursed by Landlord shall not be considered, such that the appraisal shall be
based on the condition of the demised premises as same existed on the delivery date as improved by Landlord’s Construction Contribution. 

ARTICLE XIV 
 TITLE TO PREMISES

 Landlord represents and warrants to Tenant that Landlord is the owner of the demised premises, and that there are no other individuals or
entities having an ownership interest in the demised premises whatsoever except as expressly stated in this lease, and that Landlord has full right, power and authority, corporate and otherwise, to execute this lease, to lease the demised premises
and to perform the obligations of Landlord under this lease. Landlord shall provide Tenant with its most recent commitment of title insurance or other proof adequate to Tenant, to insure that Landlord has title to the demised premises, unencumbered
by claims which may disturb Tenant’s enjoyment of the demised premises and that no tax liens exist against the demised premises. 

Landlord warrants to Tenant that, by paying the rent provided for in this lease and performing Tenant’s obligations under this lease,
Tenant will be entitled to peaceably and quietly enjoy the demised premises and all rights and appurtenances thereto during the lease Term, without molestation or hindrance of any person whomsoever.

TENANT’S WORK 

Except as otherwise set forth on Exhibit B, all work needed to prepare the demised premises for Tenant’s occupancy shall be Tenant’s
responsibility and is herein called “Tenant’s Work”. Except to the extent (if any) expressly provided to the contrary in Exhibit B hereof, Tenant’s Work shall include, without limitation, furnishing any distribution facilities
within the demised premises for utilities (including, without limitation, electricity, water and sewerage) required to meet Tenant’s needs. 

Tenant shall submit to Landlord for its approval plans and specifications for Tenant’s Work. Landlord shall have twenty (20) days
from the date of submission to approve or disapprove such plans and specifications. In the event of disapproval, Landlord shall give written notice of the same to Tenant and within fifteen (15) days from the date of such notice, Tenant shall
