EXHIBIT B

Form of Genezen Guaranty

GUARANTY

This GUARANTY (this “Guaranty”) dated as of _________, 2024 is made by GENEZEN HOLDINGS, INC., a Delaware corporation (the “Guarantor”), in favor of uniQure, Inc., a Delaware limited liability company (“Assignor”) and uniQure N.V., a public limited liability company organized under the laws of the Netherlands (“uniQure Guarantor”).

Assignor has agreed to assign that certain Lease dated as of July 24, 2013 by and between Assignor, as tenant, and Hartwell Innovation Campus, LLC, as successor in interest to King 113 Hartwell LLC, as landlord (“Landlord”), as amended by that certain First Amendment dated as of November 9, 2018, that certain Second Amendment dated as of June 17, 2019 and that certain Landlord Consent to Assignment and Assumption of Lease and Third Amendment to Lease dated as of even date herewith (collectively, the “Lease”) with respect to approximately 83,998 rentable square feet of space (the “Premises”) within the building located at 113 Hartwell Avenue, Lexington, Massachusetts (the “Building”) to Genezen MA, Inc., a Delaware corporation (“Assignee”) pursuant to that certain Assignment and Assumption of Lease dated as of even date herewith (the “Assignment”). In order to induce Assignor to enter into the Assignment, Guarantor has agreed to execute and deliver this Guaranty to Assignor and uniQure Guarantor. For good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Guarantor hereby agrees to unconditionally guarantee the timely and punctual payment of all Rent, as defined in the Lease, and other payments required to be paid by the “Tenant” under the Lease (to the extent Assignor and/or uniQure Guarantor are liable to Landlord therefor) or by Assignee under the Assignment, and the timely and prompt full performance and observance of all the covenants, conditions and agreements therein provided to be performed and observed by the “Tenant” under the Lease (to the extent Assignor and/or uniQure Guarantor are liable to Landlord therefor) or by Assignee under the Assignment. Guarantor expressly agrees that the validity of this Guaranty and the obligations of Guarantor shall in no way be terminated, affected or impaired by reason of the granting by Landlord, Assignor and/or uniQure Guarantor of any indulgences to Assignee or by reason of the assertion by Landlord, Assignor and/or uniQure Guarantor against Assignee of any of the rights or remedies reserved to Landlord, Assignor and/or uniQure Guarantor pursuant to the provisions of the Lease or the Assignment or by the relief of Assignee from any of Assignee’s obligations under the Lease or the Assignment by operation of law or otherwise (including, but without limitation, the rejection of the Lease and/or the Assignment in connection with proceedings under the bankruptcy laws now or hereafter enacted); Guarantor hereby waiving all suretyship defenses.

The obligations of Guarantor include, but are not limited to, the payment to either Assignor or uniQure Guarantor of any monies payable by the “Tenant” under any provisions of the Lease or the Assignment, at law, or in equity, including, without limitation, any monies payable by virtue of the breach of any warranty, the grant of any indemnity or by virtue of any other covenant of the

“Tenant” and/or Assignee under the Lease (to the extent Assignor and/or uniQure Guarantor is liable to Landlord therefor) and/or the Assignment.

Guarantor’s obligations hereunder constitute a guaranty of payment and performance, and not of collection merely, and shall remain in full force and effect until all of the obligations of the “Tenant” and/or Assignee under the Lease (to the extent Assignor and/or uniQure Guarantor is liable to Landlord therefor) or the Assignment have been paid and performed in full. If at any time any payment made by Assignee to Landlord (to the extent Assignor and/or uniQure Guarantor is liable to Landlord therefor), Assignor or uniQure Guarantor is rescinded or must be otherwise restored or returned upon insolvency, bankruptcy, or reorganization of Assignee or otherwise, Guarantor’s obligations hereunder with respect to such payment shall be reinstated at such time as though such payment had not ever been made. Guarantor further agrees that its liability under this Guaranty shall be primary (and that the heading of this instrument and the use of the word “Guaranty” shall not be interpreted to limit the aforesaid primary obligations of Guarantor), and that in any right of action which shall accrue to Assignor and/or uniQure Guarantor hereunder, Assignor and/or uniQure Guarantor may, at their respective option, proceed against Guarantor, any other guarantor, and Assignee, jointly or severally, and may proceed against Guarantor without having commenced any action against or having obtained any judgment against Assignee or any other guarantor. Guarantor irrevocably waives any and all rights Guarantor may have at any time prior to performance in full of all of the guaranteed obligations under this Guaranty (whether arising directly or indirectly, by operation of law or by contract or otherwise) to assert any claim against Assignee on account of payments made under this Guaranty, including, without limitation, any and all rights of or claim for subrogation, contribution, reimbursement, exoneration and indemnity, and further waives any benefit of and any right to participate in any security deposit or other collateral which may be held by Assignor and/or uniQure Guarantor; and Guarantor will not claim any set-off or counterclaim against Assignee in respect of any liability Guarantor may have to Assignee.

Guarantor hereby waives presentment, protest, notice of default, demand for payment, and all other suretyship defenses whatsoever with respect to any payment guaranteed under this Guaranty, and agrees to pay unconditionally upon demand all amounts owed under the Lease. Guarantor further waives any setoff or counterclaim (except for any compulsory counterclaims that must be brought in an action commenced by Assignor and/or uniQure Guarantor against Assignee or Guarantor) that Assignee or Guarantor may have or claim to have against Assignor and/or uniQure Guarantor and the benefit of any statute of limitations affecting Guarantor's liability under this Guaranty. Guarantor hereby agrees to indemnify each of Assignor and uniQure Guarantor and hold each of them harmless from and against all loss and expense, including legal fees, suffered or incurred by Assignor and/or uniQure Guarantor as a result of claims to avoid any payment received by Assignor and/or uniQure Guarantor from Assignee with respect to the obligations of the “Tenant” under the Lease or by Assignee under the Assignment. If Assignor and/or uniQure Guarantor retains an attorney to enforce this Guaranty or to bring any action or any appeal in connection with this Guaranty or the collection of any payment under this Guaranty, Assignor and/or uniQure Guarantor shall be entitled to recover its reasonable attorneys’ fees, costs and disbursements in connection therewith, as determined by the court before which such action or appeal is heard, in addition to any other relief to which Assignor and/or uniQure Guarantor may be entitled.

Guarantor represents to Assignor and uniQure Guarantor that Guarantor owns, directly or indirectly, a majority of the outstanding ownership interests of Assignee.

No subletting, assignment or other transfer of the Lease, or any interest therein, shall operate to extinguish or diminish the liability of Guarantor under this Guaranty; and wherever reference is made to the liability of “Tenant” named in the Lease or “Assignee” in the Assignment, such reference shall be deemed likewise to refer to Guarantor.

All payments becoming due under this Guaranty and not paid within ten (10) days after written notice from Assignor and/or uniQure Guarantor that the same is due shall bear interest from the applicable due date until received by Assignor and/or uniQure Guarantor at the rate set forth in Section 5.4 of the Lease for late payments.

It is further agreed that all of the terms and provisions hereof shall inure to the benefit of the heirs, executors, administrators and assigns of Assignor and uniQure Guarantor, and shall be binding upon the heirs, successors and assigns of Guarantor. Each reference in this Guaranty to Guarantor shall be deemed to include the successors and assigns of Guarantor, all of whom shall be bound by the provisions of this Guaranty; provided, however, notwithstanding any such assignment, the original Guarantor shall remain fully and completely liable and responsible for all of its obligations, duties, and liabilities under this Guaranty. In no event shall this Guaranty be assigned, transferred, modified or amended without the prior written consent of both Assignor and uniQure Guarantor in each instance.

Guarantor shall at any time and from time to time upon not less than thirty (30) days’ prior written notice from Assignor and/or uniQure Guarantor, execute, acknowledge and deliver to Assignor and uniQure Guarantor a statement in writing certifying that this Guaranty is unmodified and in full force and effect (or if there have been modifications, that the same is in full force and effect as modified and stating the modifications), it being intended that any such statement delivered pursuant hereto may be relied upon by Assignor and uniQure Guarantor and their respective successors and assigns.

Guarantor hereby agrees that this Guaranty shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts, without regard to principles of conflict of laws. Guarantor hereby agrees that all actions to enforce this Guaranty, and all disputes arising, directly or indirectly, out of or relating to this Guaranty, shall be dealt with and adjudicated in the state courts of the Commonwealth of Massachusetts or the federal courts for the Commonwealth of Massachusetts and for that purpose hereby expressly and irrevocably submits itself to the sole and exclusive jurisdiction of such courts. Guarantor waives any and all rights under the laws of any state or the United States or otherwise to object to such jurisdiction. Guarantor hereby irrevocably appoints Tenant as its agent for service of process in connection with any such action. Guarantor agrees that so far as is permitted under applicable law, this consent to personal jurisdiction shall be self-operative and no further instrument or action, other than service of process as otherwise permitted by law, shall be necessary in order to confer jurisdiction upon it in any such court.

Notices given under this Guaranty shall be in writing and delivered, sent or transmitted in the manner set forth in the Assignment (i) if to Assignor and/or uniQure Guarantor, to c/o uniQure, Inc., One Hartwell Place, Lexington, MA 02421, Attn: Chief Legal Officer, Email:

Sucoff, Esq., or such other address as Assignor, uniQure Guarantor or Guarantor has specified by written notice to the other. Except as otherwise specifically required herein, notice of the exercise of any right, option or power granted to Assignor and/or uniQure Guarantor by this Guaranty is not required to be given.

Unless Guarantor is traded on a U.S. public stock exchange or other public stock exchange providing financial information in English readily available in the Boston area (whether via the internet or otherwise), Guarantor shall deliver to Assignor and/or uniQure Guarantor, within thirty (30) days after Assignor and/or uniQure Guarantor’s reasonable request (which request may be made no more than once per calendar year) Guarantor’s most recently completed audited financial statements, and if Guarantor does not have audited financial statements Guarantor shall deliver unaudited financial statements. Any such financial information may be relied upon by Assignor and/or uniQure Guarantor.

Capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Lease.
