**Item 1.01 Entry into a Material Definitive Agreement.**

Non-Exclusive License Agreement

On March 23, 2023, CRISPR Therapeutics AG ("CRISPR") entered into a Non-Exclusive License Agreement (the "Non-Ex License") with Vertex Pharmaceuticals Incorporated ("Vertex"), pursuant to which CRISPR agreed to license to Vertex, on a non-exclusive basis, certain of its gene editing intellectual property to exploit certain products for the diagnosis, treatment or prevention of diabetes type 1, diabetes type 2 or insulin dependent/requiring diabetes throughout the world.

The Non-Ex License includes, among other things, provisions relating to the following:

Financial Terms. In connection with entering into the Non-Ex License, CRISPR will receive a $100.0 million up-front payment from Vertex. CRISPR is eligible to receive milestone payments from Vertex of up to $230.0 million in the aggregate, depending on the achievement of pre-determined research, development and commercial milestones for certain products utilizing the licensed intellectual property. CRISPR is also eligible to receive tiered royalties on the sales of certain products in the low to mid-single digits. In the event of any termination or expiration of the Non-Ex License, tiered royalties on the sales of certain products will continue in the low to mid-single digits.

Termination. Either party may terminate the Non-Ex License upon the other party's material breach, subject to specified notice and cure provisions. CRISPR may also terminate the Non-Ex License in the event Vertex commences or participates in any action or proceeding challenging the validity or enforceability of any patent that is licensed to Vertex pursuant to the Non-Ex License. Vertex may also terminate the Non-Ex License upon CRISPR's bankruptcy or insolvency, or for convenience upon the earlier of the achievement of certain milestone events or a specified period of time, after giving written notice.

The foregoing description of the Non-Ex License is only a brief description of the terms of such agreement, does not purport to be a complete description of the rights and obligations of the parties thereunder, and is qualified in its entirety by such agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated by reference herein.

Vertex will pay royalties to CRISPR under this Section 4.3 on a Product-by-Product and a country-by-country basis during the Royalty Term for the applicable Product in the applicable country. Upon the expiration of the Royalty Term for a given Product in a given country, the License with respect to such Product will become fully-paid, perpetual and irrevocable with respect to such Product in such country.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.3.3.**<u>Royalty Reports</u>**. During the Agreement Term, following the first sale of a Product giving rise to Net Sales and continuing for the remainder of the Royalty Term for such Product, within [\*\*\*] days after the end of each Calendar Quarter, Vertex will deliver a report to CRISPR specifying on a Product-by-Product and country-by-country basis: (a) gross sales in the relevant Calendar Quarter, (b) Net Sales in the relevant Calendar Quarter, including an accounting of deductions applied to determine Net Sales; (c) to the extent such Net Sales include sales not denoted in U.S. Dollars, a summary of the then-current exchange rate methodology used for the calculation of Net Sales in accordance with Section 4.5.2, and (d) royalties payable on such Net Sales. All royalty payments due under Section 4.3.1 for each Calendar Quarter will be due and payable within [\*\*\*] days after Vertex's delivery of the applicable report under this Section 4.3.3.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.3.4.**<u>Flash Reports</u>**. As soon as practicable, but in no event later than [\*\*\*] Business Days from the last day of each Calendar Quarter, Vertex will provide CRISPR with a flash report providing a good faith estimate of Net Sales accrued in the preceding Calendar Quarter and the royalties payable to CRISPR on such Net Sales on a Product-by-Product and country-by-country basis. The flash report may be based on forecasted numbers and it is understood that final reported Net Sales for purposes of calculating the royalty owed under Section 4.3.1 may vary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.4.**<u>Payments Under CRISPR In-License Agreements</u>**. Amounts payable by Vertex under Section 2.5.1 will be due within [\*\*\*] days of Vertex's receipt of an invoice therefore from CRISPR. Subject to Section 7.1, any other payment obligations arising under the CRISPR In-License Agreements as a result of the Exploitation of a Product Candidate or Product by Vertex or its Affiliates and Sublicensees under this Agreement will be paid solely by CRISPR.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.5.**<u>Payment Method; Currency</u>**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.5.1.All payments under this Agreement are expressed in U.S. Dollars and will be paid in U.S. Dollars, by wire transfer or ACH transfer to an account designated by CRISPR (which account CRISPR may update from time to time in writing).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.5.2.If any amounts that are relevant to the determination of amounts to be paid under this Agreement or any calculations to be performed under this Agreement are denoted in a currency other than U.S. Dollars, then such amounts will be converted to their U.S. Dollar equivalent using Vertex's then-current standard procedures and methodology, including its then-current standard exchange rate methodology for the translation of foreign currency

------

expenses into U.S. Dollars or, in the case of Sublicensees, such similar methodology, consistently applied.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.6.**<u>Withholding Tax</u>**. Where any sum due to be paid to CRISPR hereunder is subject to any withholding or similar tax, Vertex will pay such withholding or similar tax to the appropriate Governmental Authority and deduct the amount paid from the amount then due to CRISPR. Vertex will in a timely manner transmit to CRISPR an official tax certificate or other evidence of such withholding sufficient to enable CRISPR to claim such payment of taxes. The Parties will cooperate with one another and use reasonable efforts to reduce or eliminate tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by Vertex to CRISPR under this Agreement. CRISPR will provide Vertex any tax forms that may be reasonably necessary in order for Vertex not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Each Party will provide the other with reasonable assistance to enable the recovery, as permitted by Applicable Laws, of withholding taxes, value added taxes, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or value added tax.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.7.**<u>Records</u>**. During the Agreement Term, Vertex will keep and maintain accurate and complete records regarding Net Sales during the [\*\*\*] preceding Calendar Years. Upon [\*\*\*] days' prior written notice from CRISPR, Vertex will permit an independent certified public accounting firm of internationally recognized standing, selected by CRISPR and reasonably acceptable to Vertex, to examine the relevant books and records of Vertex and its Affiliates, as may be reasonably necessary to verify the royalty reports submitted by Vertex in accordance with Section 4.3.3. An examination by CRISPR under this Section 4.7 will occur not more than [\*\*\*] in any Calendar Year and will be limited to the pertinent books and records for any Calendar Year ending not more than [\*\*\*] months before the date of the request. The accounting firm will be provided access to such books and records at Vertex's facility or facilities where such books and records are normally kept and such examination will be conducted during Vertex's normal business hours. Vertex may require the accounting firm to sign a customary non-disclosure agreement before providing the accounting firm access to its facilities or records. Upon completion of the audit, the accounting firm will provide both Parties a written report disclosing whether the reports submitted by Vertex are correct or incorrect and the specific details concerning any discrepancies. No other information will be provided to CRISPR. If the report or information submitted by Vertex resulted in an underpayment or overpayment, the Party owing the underpaid or overpaid amount will promptly pay such amount to the other Party, and, if, as a result of such inaccurate report or information, such amount is more than [\*\*\*] of the amount that was owed Vertex will reimburse CRISPR for the reasonable expense incurred by CRISPR in connection with the audit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.8.**<u>Late Payment</u>**. Any payments or portions thereof due hereunder that are not paid when due will accrue interest from the date due until paid at an annual rate equal to [\*\*\*] (or the maximum allowed by Applicable Law, if less).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.3.**<u>Patent Costs</u>**. Patent Costs arising after the Effective Date will be borne by Party responsible for the Prosecution and Maintenance of the applicable Patent under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.4.**<u>Defense of Claims Brought by Third Parties</u>**. If a Third Party initiates a Proceeding against either Party claiming a Patent owned by or licensed to such Third Party is infringed by the Exploitation of a Product Candidate or a Product, each Party that is named as a defendant in such Proceeding will have the right to defend itself in such Proceeding. The other Party will reasonably assist the defending Party in defending such Proceeding and cooperate in any such litigation at the request and expense of the defending Party. The defending Party will provide the other Party with prompt written notice of the commencement of any such Proceeding and will keep the other Party apprised of the progress of such Proceeding and will promptly furnish the other Party with a copy of each communication relating to the alleged infringement that is received by such Party. If both Parties are named as defendants in any Proceeding, both Parties may defend such Proceeding and the Parties will reasonably cooperate with respect to such defense.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.5.**<u>Infringement</u>**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.5.1.**<u>Patents Solely Owned by CRISPR</u>**.

In the event of a conflict between the Parties' rights and obligations under the ViaCyte/CRISPR Collaboration Agreement or any Other CRISPR-Vertex Agreement and the Parties' rights and obligations under this ARTICLE 5, the applicable terms of the ViaCyte/CRISPR Collaboration Agreement or any Other CRISPR-Vertex Agreement will control.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.7.**<u>Patent Listing</u>**. Vertex will have the sole right, but not the obligation, to submit to all applicable Regulatory Authorities patent information pertaining to each applicable Product pursuant to 21 U.S.C. § 355(b)(1)(G) (or any amendment or successor statute thereto), any similar statutory or regulatory requirement enacted in the future regarding biologic products, or any similar statutory or regulatory requirement in any non-U.S. country or other regulatory jurisdiction; provided that Vertex shall not be permitted to provide any such information with respect to Licensed Patents without CRISPR's prior written consent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.8.**<u>Common Ownership Legislation</u>**. Notwithstanding anything to the contrary in this ARTICLE 5, neither Party will have the right to make an election under the Common Ownership Legislation when exercising its rights under this ARTICLE 5 without the prior written consent of the other Party, which will not be unreasonably withheld, conditioned or delayed. With respect to any such permitted election, the Parties will use reasonable efforts to cooperate and coordinate their activities with respect to any submissions, filings or other activities in support thereof.

Notwithstanding the foregoing, the other Party's consent under this Section 5.8 will not be required in connection with an obviousness-type double patenting rejection in any patent application claiming a Product or uses thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.9.**<u>Patent Term Extension</u>**. The Parties will cooperate with each other in obtaining patent term restoration in any country in the Territory under any statute or regulation equivalent or similar to 35 U.S.C. § 156, where applicable to a Product. Vertex, its Affiliates and Sublicensees shall not seek to obtain patent term restoration with respect to any Licensed Patents without prior written consent of CRISPR, such consent to be granted at CRISPR's sole discretion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.10.**<u>Recording</u>**. If Vertex deems it necessary or desirable to register or record this Agreement or evidence of this Agreement with any patent office or other appropriate Governmental Authority in one or more jurisdictions in the Territory, CRISPR will reasonably cooperate to execute and deliver to Vertex any documents accurately reflecting or evidencing this Agreement that are necessary or desirable, in Vertex's reasonable judgment, to complete such registration or recordation. Vertex will reimburse CRISPR for all reasonable Out-of-Pocket Costs, including attorneys' fees, incurred by CRISPR in complying with the provisions of this Section 5.10.

**ARTICLE 7.** **<br>INDEMNIFICATION; INSURANCE**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.1.**<u>Indemnification by Vertex</u>**. Vertex will indemnify, defend and hold harmless CRISPR, each of its Affiliates, and each of its and its Affiliates' employees, officers, directors and agents (each, an "**CRISPR Indemnified Party**") from and against any and all liability, loss, damage, expense (including reasonable attorneys' fees and expenses) and cost (collectively, a "**Liability**") that the CRISPR Indemnified Party may be required to pay to one or more Third Parties to the extent resulting from or arising out of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.1.1.any claims of any nature arising out of the Exploitation of any Product by, on behalf of, or under the authority of, Vertex (other than by any CRISPR Indemnified Party), other than (a) claims by Third Parties relating to misappropriation of trade secrets or other intellectual property rights arising out of the exercise of rights under the Licensed Know-How, or (b) claims for which CRISPR is required to indemnify Vertex pursuant to Section 7.2; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.1.2.the material breach by Vertex of any of its representations, warranties or covenants set forth in this Agreement, except to the extent caused by the negligence or intentional acts of CRISPR or any CRISPR Indemnified Party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.2.**<u>Indemnification by CRISPR</u>**. CRISPR will indemnify, defend and hold harmless Vertex, its Affiliates, Sublicensees, Distributors and each of its and their respective employees, officers, directors and agents (each, a "**Vertex Indemnified Party**") from and against any and all Liabilities that the Vertex Indemnified Party may be required to pay to one or more Third Parties to the extent resulting from or arising out of the material breach by CRISPR of any of its representations, warranties or covenants set forth in this Agreement, except to the extent caused by the negligence or intentional acts of Vertex or any Vertex Indemnified Party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.3.**<u>Procedure</u>**. Each Party will notify the other Party in writing if it becomes aware of a claim for which indemnification may be sought hereunder. In case any proceeding (including any governmental investigation) will be instituted involving any Party in respect of which indemnity may be sought pursuant to Section 7.1 or Section 7.2, as applicable, such Party (the "**Indemnified Party**") will give prompt written notice of the indemnity claim to the other Party (the "**Indemnifying Party**") and provide a copy to the Indemnifying Party of any complaint, summons or other written or verbal notice that the Indemnified Party receives in connection with any such claim. An Indemnified Party's failure to deliver written notice will relieve the Indemnifying Party of liability to the Indemnified Party under Section 7.1 or Section 7.2, as applicable, only to the extent such delay is prejudicial to the Indemnifying Party's ability to defend such claim. Provided that the Indemnifying Party is not contesting the indemnity obligation, the Indemnified Party will permit the Indemnifying Party to control any litigation relating to such claim and the disposition of such claim by negotiated settlement or otherwise and any failure to contest prior to assuming control will be deemed to be an admission of the obligation to indemnify. The Indemnifying Party will act reasonably and in good faith with respect to all matters relating to such claim and will not settle or otherwise resolve such claim without the Indemnified Party's prior written consent which will not be withheld, delayed or conditioned unreasonably other than settlements only involving the payment of monetary awards for which the Indemnifying Party will be fully-responsible. The Indemnified Party will cooperate with the Indemnifying Party in such Party's defense of

------

any claim for which indemnity is sought under this Agreement, at the Indemnifying Party's sole cost and expense.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.4.**<u>Insurance</u>**. Each Party will maintain, at its cost, reasonable insurance against liability and other risks associated with its activities contemplated by this Agreement and will furnish to the other Party evidence of such insurance upon request. Notwithstanding the foregoing, Vertex may self-insure to the extent that it self-insures for its other activities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.5.**<u>Limitation of Consequential Damages</u>**. EXCEPT FOR (A) CLAIMS OF A THIRD PARTY THAT ARE SUBJECT TO INDEMNIFICATION UNDER THIS ARTICLE 7, (B) CLAIMS ARISING OUT OF A PARTY'S WILLFUL MISCONDUCT, OR (C) A PARTY'S BREACH OF ARTICLE 9, NEITHER PARTY NOR ANY OF ITS AFFILIATES WILL BE LIABLE TO THE OTHER PARTY OR ITS AFFILIATES FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL, PUNITIVE OR OTHER INDIRECT DAMAGES OR LOST OR IMPUTED PROFITS OR ROYALTIES, LOST DATA OR COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE.

**ARTICLE 8.** **<br>TERM; TERMINATION**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.1.**<u>Agreement Term; Expiration</u>**. This Agreement is effective as of the Effective Date and, unless earlier terminated pursuant to the other provisions of this ARTICLE 8, will expire, in its entirety, upon the expiration of the last to expire Royalty Term under this Agreement with respect to all Products in all countries.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.2.**<u>Termination of this Agreement</u>**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.2.1.**<u>Vertex's Termination for Convenience</u>**. Vertex may, at any time after the earlier of (i) [\*\*\*] or (ii) the [\*\*\*] anniversary of the Effective Date, terminate this Agreement (either in its entirety or on a Product-by-Product basis) for convenience by providing CRISPR [\*\*\*] days' written notice of such termination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.2.2.**<u>Termination for Material Breach</u>**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)**<u>Vertex's Right to Terminate</u>**. If Vertex believes that CRISPR is in material breach of this Agreement, then Vertex may deliver written notice of such material breach to CRISPR. If the breach is curable, CRISPR will have [\*\*\*] days from the receipt of such written notice to cure such breach. If CRISPR fails to cure such breach within such [\*\*\*]-day period or the breach is not subject to cure (a "**CRISPR Breach Event**"), Vertex in its sole discretion may terminate this Agreement by providing written notice to CRISPR; provided, however, that if (A) the relevant breach is curable, but not reasonably curable within [\*\*\*] days, and (B) CRISPR is making a bona fide effort to cure such breach, Vertex's right to terminate this Agreement on account of such breach will be suspended for a period of up to [\*\*\*] days, provided that CRISPR is

------

continuing to make such bona fide effort to cure such breach and if such breach is successfully cured, Vertex will no longer have the right to terminate this Agreement on account of such breach.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)**<u>CRISPR's Right to Terminate</u>**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)If CRISPR believes that Vertex is in material breach of this Agreement, then CRISPR may deliver written notice of such material breach to Vertex. If the breach is curable, Vertex will have [\*\*\*] days from the receipt of such written notice to cure such breach (except to the extent such breach involves the failure to make a payment when due, which breach must be cured within [\*\*\*] Business Days following receipt of such written notice). If Vertex fails to cure such breach within the [\*\*\*]-day or [\*\*\*]-Business Day period, as applicable, or the breach is not subject to cure, CRISPR in its sole discretion may terminate this Agreement by providing written notice to Vertex; provided, however, that if (i) the relevant breach (A) does not involve Vertex's failure to make a payment when due and (B) is curable, but not reasonably curable within [\*\*\*] days, and (ii) Vertex is making a bona fide effort to cure such breach, CRISPR's right to terminate this Agreement on account of such breach will be suspended for a period of up to [\*\*\*] days, provided that Vertex is continuing to make such bona fide effort to cure such breach and if such breach is successfully cured, CRISPR will no longer have the right to terminate this Agreement on account of such breach.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)If Vertex (A) commences or actively and voluntarily participates in any action or proceeding (including any patent opposition or re-examination proceeding), or otherwise asserts any claim, challenging or denying the validity or enforceability of any claim of any Patent that is licensed to Vertex under this Agreement or (B) actively and voluntarily assists any other Person in bringing or prosecuting any action or proceeding (including any patent opposition or re-examination proceeding) challenging or denying the validity or enforceability of any claim of any Patent that is licensed to Vertex under this Agreement (each of (A) and (B), a "**Patent Challenge**"), then, to the extent permitted by Applicable Law, CRISPR shall have the right, in its sole discretion, to give notice to Vertex that CRISPR may terminate the license(s) granted under such Patent to Vertex [\*\*\*] days following such notice, and, unless Vertex withdraws or causes to be withdrawn all such challenge(s) (or in the case of ex-parte proceedings, multi-party proceedings, or other Patent Challenges that Vertex does not have the power to unilaterally withdraw or cause to be withdrawn), Vertex ceases assisting any other party to such Patent Challenge and, to the extent Vertex is a party to such Patent Challenge, it withdraws from such Patent Challenge within such [\*\*\*]-day period, CRISPR shall have the right to terminate this Agreement by providing written notice thereof to Vertex. The foregoing right to terminate shall not apply with respect to any Patent Challenge where the Patent Challenge is made in defense of an assertion of the relevant Patent that is first brought by CRISPR against Vertex. For the avoidance of doubt, any participation by Vertex or its employees in any claim, challenge or proceeding in response to a subpoena or as required under a

------

pre-existing agreement between Vertex's employee(s) or consultant(s) and their prior employer(s) shall not constitute active and voluntary participation or assistance and shall not give rise to CRISPR's right to terminate any license hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.2.3.**<u>Disputes Regarding Material Breach</u>**. Notwithstanding the foregoing, if the Breaching Party in Section 8.2.2 disputes in good faith the existence, materiality, or failure to cure of any such breach and provides written notice to the Non-Breaching Party of such dispute within the relevant cure period, the Non-Breaching Party will not have the right to terminate this Agreement in accordance with Section 8.2.2, unless and until the relevant dispute has been resolved. Any dispute not resolved through the Parties' good faith discussions shall be referred to the Executive Officers for resolution. If the Executive Officers are unable to resolve any such dispute within [\*\*\*] days after the date such reference is made to the Executive Officers, either Party may pursue any rights or remedies of such Party under this Agreement at law or in equity. It is understood and acknowledged that during the pendency of such dispute, the relevant cure period shall be tolled, all the terms and conditions of this Agreement will remain in effect and the Parties will continue to perform all of their respective obligations hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.2.4.**<u>Termination for Insolvency</u>**. If CRISPR makes an assignment for the benefit of creditors, appoints or suffers appointment of a receiver or trustee over all or substantially all of its property, files a petition under any bankruptcy or insolvency act or code, including the U.S. Bankruptcy Code, or has any such petition filed against it that is not discharged within [\*\*\*] days of the filing thereof, or is unable to pay its debts as they come due (each, an "**Insolvency Event**"), then Vertex may terminate this Agreement in its entirety effective immediately upon written notice to CRISPR.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.3.**<u>Consequences of Expiration or Termination of this Agreement</u>**. If this Agreement expires or is terminated by a Party in accordance with this ARTICLE 8, at any time and for any reason, the following terms will apply to any Product in any country that is the subject of such expiration or termination (or, if this Agreement expires or is terminated in its entirety, to all Products in all countries):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.3.1.Solely in the event of a termination of this Agreement, the Parties will return (or destroy, as directed by the other Party) all data, files, records and other materials containing or comprising the other Party's Confidential Information, except to the extent such Confidential Information (i) is subject to a license or similar grant of rights that survives such termination, (ii) is necessary or useful to conduct activities for surviving Products, or (iii) is Confidential Information under an Other CRISPR-Vertex Agreement and such Other CRISPR-Vertex Agreement has not been terminated at the time of termination of this Agreement. Notwithstanding the foregoing, the Parties will be permitted to retain one copy of such data, files, records, and other materials for archival and legal compliance purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.3.2.Termination or expiration of this Agreement for any reason will be without prejudice to any rights or financial compensation that will have accrued to the benefit of a Party prior to such termination or expiration. Such termination or

------

expiration will not relieve a Party from obligations that are expressly indicated to survive the termination or expiration of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.3.3.The following provisions of this Agreement will survive any expiration or termination of this Agreement: ARTICLE 1 (Definitions), Section 2.1.1 (License Grant to Vertex) (to the extent set forth in Section 4.3.2), Section 2.3 (No Implied Licenses), Section 4.5 (Payment Method; Currency) through Section 4.8 (Late Payment) (in each case, solely to the extent of accrued obligations as contemplated by Section 8.3.2 and any payment obligations arising in respect of [\*\*\*] Products after the effective date of termination pursuant to the final sentence of this Section 8.3.3), Section 5.1 (Ownership; Assignment), Section 5.4 (Defense of Claims Brought by Third Parties) through Section 5.5 (Other Infringement) (in each case, with respect to proceedings to the extent relating to events occurring prior to the effective date of termination), Section 5.8 (Common Ownership Legislation), ARTICLE 7 (Indemnification; Insurance) (but excluding Section 7.4 (Insurance)), this Section 8.3 (Consequences of Expiration or Termination of this Agreement), Section 9.1 (Confidentiality) through Section 9.4 (Residual Knowledge Exception), and ARTICLE 10 (Miscellaneous). Except with respect to any termination by Vertex under Section 8.2.2(a) (Vertex's Right to Terminate), in the event of a termination of this Agreement, Vertex's payment obligations set forth in Section 4.3.1 (Royalty Rates) shall survive such termination of this Agreement solely with respect to any [\*\*\*] Products [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.3.4.Except as set forth in Section 8.3.5, in the event of a termination of this Agreement, either with respect to a Product or in its entirety, the applicable licenses granted by CRISPR to Vertex under this Agreement will terminate and Vertex and its Affiliates will cease all Exploitation activities with respect to the applicable terminated Products, except for any [\*\*\*] Product [\*\*\*].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.3.5.Any permitted Sublicense of Vertex will, at the Sublicensee's option, survive such termination; provided that the relevant Sublicensee is not in material breach of any of its obligations under such Sublicense. In order to effect this provision, at the request of the Sublicensee, CRISPR will enter into a direct license with the Sublicensee on substantially the same terms as this Agreement (taking into account the scope of the licensee granted under such Sublicense); provided that CRISPR will not be required to undertake obligations in addition to those required by this Agreement, and that CRISPR's rights under such direct license will be consistent with its rights under this Agreement, taking into account the scope of the license granted under such direct license.

**ARTICLE 9.** **<br>CONFIDENTIALITY**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.1.**<u>Confidentiality</u>**. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing, the Parties agree that, during the Agreement Term and for [\*\*\*] years thereafter, each Party (the "**Receiving Party**") receiving any Confidential Information of the other Party (the "**Disclosing Party**") hereunder will: (a) keep the Disclosing Party's Confidential Information confidential; (b) not publish, or allow to be published, and will not otherwise disclose, or permit the disclosure of, the Disclosing Party's Confidential Information in any manner not expressly authorized pursuant to the terms of this Agreement

or, to the extent Confidential Information under this Agreement is also Confidential Information under an Other CRISPR-Vertex Agreement, such Other CRISPR-Vertex Agreement; and (c) not use, or permit to be used, the Disclosing Party's Confidential Information for any purpose other than as expressly authorized pursuant to the terms of this Agreement or, to the extent Confidential Information under this Agreement is also Confidential Information under an Other CRISPR-Vertex Agreement, the terms of such Other CRISPR-Vertex Agreement. Without limiting the generality of the foregoing, to the extent that a Party or any of its Affiliates provides to the other Party or any of its Affiliates any Confidential Information owned by any Third Party, the receiving Party will, and will cause its Affiliates to, handle such Confidential Information in accordance with the terms and conditions of this ARTICLE 9 applicable to a Receiving Party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.2.**<u>Authorized Disclosure</u>**. Notwithstanding Section 9.1, each Party may disclose Confidential Information belonging to the other Party to the extent such disclosure is reasonably necessary to:

If a Party deems it reasonably necessary to disclose Confidential Information belonging to the other Party pursuant to this Section 9.2, the Disclosing Party will to the extent possible give reasonable advance written notice of such disclosure to the other Party and take reasonable measures to ensure confidential treatment of such information. In addition to the foregoing and except as otherwise prohibited or limited by clause (b) of the following sentence, [\*\*\*] may disclose [\*\*\*] Confidential Information to Third Parties as reasonably required to facilitate the actual or potential Exploitation of Products; provided that such disclosure is covered by terms of confidentiality and non-use similar to those set forth herein.

**Vertex and CRISPR Therapeutics Announce Licensing Agreement to Accelerate Development of Vertex's Hypoimmune Cell Therapies for the Treatment of Type 1 Diabetes**

-Vertex to receive non-exclusive rights to CRISPR Therapeutics' CRISPR/Cas9 to accelerate development of potentially curative cell therapies for T1D-<br>

-CRISPR Therapeutics to receive $100M upfront payment plus milestone and royalty payments on potential future gene-edited hypoimmune T1D products -

BOSTON and ZUG, Switzerland–March 27, 2023 -- Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) and CRISPR Therapeutics (Nasdaq: CRSP) today announced that they have entered into a new non-exclusive licensing agreement for the use of CRISPR Therapeutics' gene editing technology, known as CRISPR/Cas9, to accelerate the development of Vertex's hypoimmune cell therapies for type-1 diabetes (T1D).

"We have multiple programs in our T1D portfolio including VX-880 and VX-264, which are in the clinic, as well as our hypoimmune program, in preclinical development," said Bastiano Sanna, Ph.D., Executive Vice President and Chief of Cell and Genetic Therapies. "Having successfully demonstrated clinical proof of concept in T1D in our VX-880 program, we are excited to deepen our relationship with CRISPR Therapeutics with this agreement, which will allow us to further accelerate our goal of generating fully differentiated, insulin-producing hypoimmune islet cells for T1D."

"We are pleased to expand our long and successful relationship with Vertex with this collaboration which fully leverages our gene editing platform to develop hypoimmune cell therapies for T1D," said Samarth Kulkarni, Ph.D., Chief Executive Officer of CRISPR Therapeutics. "In parallel, we continue to expand our capabilities in regenerative medicine and advance our existing allogeneic gene-edited cell therapy programs."<br>Under this agreement, Vertex will pay CRISPR Therapeutics $100 million up-front for non-exclusive rights to CRISPR Therapeutics' technology for the development of hypoimmune gene edited cell therapies for T1D. CRISPR Therapeutics will be eligible for up to an additional $230 million in research and development milestones and receive royalties on any future products resulting from this agreement.

CRISPR and ViaCyte, Inc., which was acquired by Vertex in 2022, will continue to collaborate on their existing gene-edited allogeneic stem cell therapies, using ViaCyte cells, for the treatment of diabetes under the terms of their collaboration. A Phase 1/2 study of VCTX211, an allogeneic, gene-edited, stem cell-derived product candidate for T1D, which originated under the CRISPR Therapeutics and ViaCyte collaboration, has been initiated and is on-going. CRISPR Therapeutics will not obtain any interest in Vertex's pre-existing pipeline of T1D products, including VX-880 and VX-264.
