RECITALS

WHEREAS, ARE-MA REGION NO. 94, LLC, a Delaware limited liability company (“Prime Landlord” or “Landlord”) entered into that certain Lease (as may be amended, the “Prime Lease”) dated November 4, 2021, whereby Prime Landlord leased to Licensor, as tenant, approximately 89,246 rentable square feet, including, among other things, approximately 10,866 rentable square feet for the Shared Space Arrangement in the building located on the first floor at 140 First Street, Cambridge, Massachusetts 02141 (the “Suite 105 Premises”).

WHEREAS, the parties acknowledge that Licensee meets the definition of a “Flagship Pioneering Entity” as set forth in Section 22(c) of the Prime Lease.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Licensor and Licensee hereby agree to the following:

License: Licensor hereby grants Licensee, and Licensee hereby accepts from Licensor, the non-exclusive license and privilege to use and operate within the Shared Space (as hereinafter defined) in accordance with the terms and conditions of this Shared Space Arrangement, together with the right to exercise, in common with Licensor and others entitled thereto, Licensor’s right to use the common areas under the Prime Lease necessary or appropriate to Licensee’s use of the Shared Space. Licensee acknowledges and agrees that it is subject to the insurance and liability provisions of the Prime Lease. This Shared Space Arrangement does not convey title to any land or buildings, and in no event shall it be deemed an estate in land or a tenancy. Licensee acknowledges and agrees that in no event shall this Shared Space Arrangement grant, or be deemed to have granted Licensee any rights whatsoever against Prime Landlord with respect to the Premises.

Shared Space: This Shared Space Arrangement shall allow Licensee to use only the space within the Suite 105 Premises consisting of approximately 10,866 rentable square feet and as more particularly, Suite 105 (the “Shared Space”), which may be amended by mutual agreement set forth in writing between the parties. Notwithstanding anything to the contrary contained herein, the parties acknowledge that a portion of the Shared Space shall be for the shared use of Licensee, Licensor and other licensees within the Premises (the “Common Areas”). The use of such Common Areas shall be in accordance with this Shared Space Arrangement and any reasonable rules and regulations promulgated for their use hereafter.

Term; License Fee:

The term (“Term”) of this Shared Space Arrangement shall commence on the Effective Date (the “Term Commencement Date”) and continue through July 31, 2027 (the “Initial

Term”). Notwithstanding the foregoing to the contrary, provided that Licensee shall not be in default beyond any applicable notice and cure periods either at the time Licensor receives the Extension Notice (as hereinafter defined) or at the commencement of the Extension Term (as hereinafter defined), and provided further that Landlord consents to each such Extension Term, Licensee shall have two (2) options to extend the Term of this Shared Space Arrangement for a period of twenty-four (24) months (each, an “Extension Term” and collectively, the “Extension Terms”). Licensee must exercise its right to extend the Term by providing written notice of the election to Licensor (an “Extension Notice”) at least six (6) months prior to each applicable termination date. In the event of such renewal, the “Term” shall include each Extension Term and each such renewal shall be upon the same provisions as for the Initial Term. In no event will the Term extend beyond the expiration of the Prime Lease. If the first Extension Term is not exercised, the second Extension Term is null and void.

Licensee will pay a “License Fee,” which is its monthly proportionate share of Tenant’s cost of the actual Base Rent and Additional Rent (each as defined in the Prime Lease), and any additional sums which are paid by Licensor for the use and occupancy of the Shared Space including but not limited to utilities, building maintenance, waste removal, alarm and security services, property management fee, parking, and the TI Rent attributable to the Shared Space. Licensee’s proportionate share of: (i) Tenant’s cost of the actual Base Rent shall be 12.2% of the actual Base Rent, (ii) Tenant’s cost of the actual Operating Expenses shall be 12.2% of Tenant’s Share of Operating Expenses of Building (as such term is defined in the basic lease information of the Prime Lease), (iii) such additional sums paid by Licensor for the use and occupancy of the Shared Space shall be 12.2% of any amounts actually charged by Prime Landlord, and (iv) the TI Rent attributable to the Shared Space shall be a monthly tenant improvement charge of $27,219 assuming that the Remaining Tenant Improvement Allowance is received by Licensor on or before August 1, 2024. In the event that the Remaining Tenant Improvement Allowance is not received by Licensor on or before August 1, 2024, Licensor and Licensee shall adjust the amount of the TI Rent to reflect the actual date of receipt.

Licensee shall begin paying the License Fee to Licensor on the Effective Date. All License Fee payments are due and payable in advance on the first day of each calendar month, without demand, deduction, counterclaim or setoff. The License Fee for any partial month shall be prorated and paid on the first of such month.

First Floor Premises Improvements: Licensee and Licensor acknowledge and agree that: (i) pursuant to the Prime Lease, Landlord previously granted Licensor rights to certain improvement allowances of which $3,270,968.87 remain (the “Remaining Tenant Improvement Allowance”), (ii) Landlord has agreed to provide the Remaining Tenant Improvement Allowance to Licensor solely for improvements to the Shared Space, subject to certain conditions, and (iii) Licensor has agreed to provide the Remaining Tenant Improvement Allowance to Licensee upon such conditions, solely for Licensee to make certain improvements to the Shared Space in accordance with the terms below:

Licensor shall make available to Licensee the Remaining Tenant Improvement Allowance, for the design and construction of fixed and permanent improvements desired by and performed by Licensee and reasonably acceptable to Landlord and Licensor, to be used only for that portion of the Premises located in Suite 105 on the first floor of the Building (the “First Floor Premises

Improvements”), which First Floor Premises Improvements shall be constructed pursuant to a scope of work, drawings and permit plans (the “Permit Plans”) reasonably acceptable to Landlord, Licensor and Licensee. The Remaining Tenant Improvement Allowance shall be available only for hard and soft costs for the design, permitting and construction of the First Floor Premises Improvements. The First Floor Premises Improvements shall be treated as Alterations under the Prime Lease and shall be undertaken pursuant to Section 12 of the Prime Lease. The contractor for the First Floor Premises Improvements shall be selected by Licensee, subject to Licensor’s and Landlord’s approval, which approval shall not be unreasonably withheld, conditioned or delayed. Prior to the commencement of the First Floor Premises Improvements, Licensee shall deliver to Licensor and Landlord a copy of any contract with Licensee’s contractors, and certificates of insurance from any contractor performing any part of the First Floor Premises Improvements evidencing industry standard commercial general liability, automotive liability, “builder’s risk”, and workers’ compensation insurance. Licensee shall cause the general contractor to provide a certificate of insurance naming Licensor, Landlord, Alexandria Real Estate Equities, Inc., and Landlord’s lender (if any) as additional insureds for the general contractor’s liability coverages required above.

Licensor shall disburse 100% of the Remaining Tenant Improvement Allowance to Licensee as soon as reasonably practical after Licensor’s receipt of the Remaining Tenant Improvement Allowance from Landlord, which receipt shall occur upon Landlord’s final approval of the Permit Plans (the “First Floor Premises Improvement Disbursement Date”). Licensee shall be obligated to pay the TI Rent to Licensor as described in Section 3(b)(iv), above. For the avoidance of doubt, the TI Rent shall not be subject to adjustment pursuant to Section 4(a) of the Lease.

Upon completion of the First Floor Premises Improvements Licensee shall deliver to Licensor and Landlord the following items: (i) sworn statements setting forth the names of all contractors and subcontractors who did work on the First Floor Premises Improvements and final lien waivers from all such contractors and subcontractors; and (ii) “as built” plans for the First Floor Premises Improvements. Licensee acknowledges that upon the expiration of the Term, the First Floor Premises Improvements shall become the property of Landlord and may not be removed by Licensee or Licensor. Except for the Remaining Tenant Improvement Allowance, Licensee shall be solely responsible for all of the costs of the First Floor Premises Improvements. If the cost of the First Floor Premises Improvements exceeds the Remaining Tenant Improvement Allowance, Licensee shall be required to pay such excess in full. Licensee shall have no right to any portion of the Remaining Tenant Improvement Allowance that is not disbursed before the last day of the month that is 9 months after the Effective Date (the “Outside Remaining Tenant Improvement Allowance Date”). Any portion of the Remaining Tenant Improvement Allowance which has not been disbursed before the Outside Remaining Tenant Improvement Allowance Date shall be forfeited to Licensor and shall not be available for use by Licensee.

Use of the Shared Space: Licensee agrees to only use the Shared Space consistent with the terms of the Prime Lease. In no event shall Licensee make any alterations to the Premises without Licensor’s prior written approval, which approval Licensor may withhold in its sole and absolute discretion. Licensor will make available to Licensee 10 of the parking spaces made available to Licensor by Prime Landlord, subject to all of the terms and conditions applicable to Licensor in the Prime Lease.

Default and Liability for Damages: Licensor may terminate this Shared Space Arrangement, effective immediately, and require Licensee to immediately vacate the Shared Space in the event (i) Licensee or any employee, agent, representative or invitee of Licensee (collectively, a “Licensee Party”) causes a default under the Prime Lease, (ii) Licensee is in default of any provision, obligation or covenant set forth in this Shared Space Arrangement, or (iii) a Licensee Party acts or behaves in a manner deemed by Licensor, in its sole discretion, as dangerous or threatening. Licensee shall be liable, and hereby accepts responsibility for any damage to equipment, furnishings, and any other property of Licensor or Prime Landlord (including, without limitation, damage to the Premises), caused by Licensee or a Licensee Party, excluding damage due to normal wear and tear. Licensee agrees to pay the cost to repair or replace (at full replacement cost) any damaged property, subject to any waivers of subrogation contained in any property insurance policies.

Indemnity: Subject to any waiver of subrogation contained in any property insurance policies held or required to be held hereunder, and except to the extent arising out the negligence or willful misconduct of Licensor or any of Licensor’s employees, agents, representatives or invitees, Licensee agrees to indemnify and save harmless Licensor and its partners, employees, agents, independent contractors, clients and invitees (each an “Indemnified Party” and collectively, the “Indemnified Parties”), from and against any and all claims, liabilities, suits, judgments, awards, damages, losses, fines, penalties, costs and expenses, including without limitation reasonable attorneys’ fees (collectively, “Claims”), that any Indemnified Party may suffer, incur or be liable for by reason of or arising out of the breach by Licensee or any Licensee Party of any of the duties, obligations, liabilities or covenants applicable hereunder or relating to its occupancy or use of the Shared Space. Licensor shall promptly notify Licensee of any such claim and shall promptly deliver to the other a copy of any summons or other process, pleading or notice issued in any action or proceeding to assert any such claim.

Subject to any waiver of subrogation contained in any property insurance policies held or required to be held hereunder, and except to the extent arising out of the negligence or willful misconduct of Licensee or any Licensee Party, Licensor agrees to indemnify and save harmless Licensee and its Indemnified Parties, from and against any and all Claims, that Licensee or its Indemnified Party may suffer, incur or be liable for by reason of or arising out of the negligence or willful misconduct by Licensor or any employee, agent, representative or invitee of Licensor relating to its occupancy or use of the Suite 105 Premises. Licensee shall promptly notify Licensor of any such claim and shall promptly deliver to the other a copy of any summons or other process, pleading or notice issued in any action or proceeding to assert any such claim.

Notwithstanding anything to the contrary contained herein, in no event shall either party be liable under this Shared Space Arrangement for any indirect, consequential or punitive damages. In no event shall the partners, principals, members, officers, stockholders, directors, employees or agents of either Licensor or Licensee be personally liable for the performance of that party’s obligations under this Shared Space Arrangement.

Confidentiality: Each party shall hold the Confidential Information (as hereinafter defined) of the other party in strict confidence and shall not use, or disclose such information to any person, except as explicitly permitted by this Shared Space Arrangement. In protecting the Confidential Information, each party shall use the same degree of care as each party uses to protect its own confidential information of a similar nature (but in no event less than a reasonable degree of care)

and shall notify the other party of any potential or actual unauthorized disclosure or use of its Confidential Information.

Each party may disclose the other party’s Confidential Information to:

its agents and employees only to the extent reasonably necessary to accomplish the purposes of this Shared Space Arrangement and only with the express agreement by such employees and agents that the Confidential Information is to be maintained under confidentiality and nonuse obligations that are no less protective than those in this Shared Space Arrangement; and

to the extent required by applicable law, court order, or in any litigation in connection with this Shared Space Arrangement.

ii.

If either party is required to disclose any of the other party’s Confidential Information pursuant to Section 7(i) above, such party will, if permitted, provide the party whose Confidential Information is being disclosed with reasonable, prior notice of the requirement and assistance (at such party’s expense) so that the party that is the owner of the Confidential Information may seek to oppose the requirement to disclose or obtain a protective order preserving the confidentiality of any of its Confidential Information so disclosed.

iii.

“Confidential Information” shall mean: (a) all business information heard, seen or in any manner learned by either party or its respective agents, employees or Visitors (defined below) due to the parties’ shared use of the Suite 105 Premises; (b) all information that has been or may be disclosed to either party, its employees, or agents orally or in writing, by the other party, its respective employees or agents in connection with, or incidental to, this Shared Space Arrangement or any other business dealing between Licensor and Licensee; and (c) the terms of this Shared Space Arrangement.

The Confidential Information shall not include information that (i) is or becomes available to the public through no fault of a party or its respective agents, employees or Visitors, or (ii) the receiving party can show by written records was acquired in good faith on a non-confidential basis from a third party. “Visitors” shall mean: all persons permitted to access the Suite 105 Premises by or because of either party.

Each party shall be directly liable to the other party for breaches of the confidentiality obligations set forth herein by the receiving party and its respective employees, agents and Visitors. Upon a disclosing party’s request, the receiving party shall destroy, erase, or return to the disclosing party, in a manner reasonably acceptable to the disclosing party, all Confidential Information in its possession or control.

Each party hereby acknowledges and agrees that money damages alone would be an inadequate remedy for the injuries and damage that would be suffered and incurred by either disclosing party as a result of a breach of any of the confidentiality provisions of this Shared Space Arrangement. Accordingly, a disclosing party shall be entitled to equitable relief, including injunctive relief and specific performance, to prevent or end a breach of the confidentiality provisions of this Shared Space Arrangement without the need to show irreparable harm or to submit proof of the economic value of any Confidential Information. Such equitable relief shall not be deemed to be the

exclusive remedy for any breach of this Shared Space Arrangement, but shall be in addition to all other remedies at law or in equity.

Each party’s obligations of confidentiality and nonuse of the Confidential Information under this Shared Space Arrangement shall survive the termination of this Shared Space Arrangement.

Insurance: Licensee shall carry and maintain the same insurance policies and in such amounts that are applicable to Licensor under the Prime Lease, and Licensee shall have Licensor and Prime Landlord named as additional insureds under such policies.

10.

Such a reasonable record can include printed or electronic copies of said communications.
