Rights Agreement, dated as of August 20, 2015 (as amended or otherwise modified from time to time, the “Investors’ Rights Agreement”), by and among the Company and the other parties thereto. 

WITNESSETH 
 WHEREAS, the
Company and the Investors are parties to the Investors’ Rights Agreement; 
 WHEREAS, pursuant to
Subsection 6.6 of the Investors’ Rights Agreement, the Investors’ Rights Agreement may be amended by the written consent of (a) the Company and (b) stockholders then holding shares of Preferred Stock representing
at least sixty-seven percent (67%) of the combined voting power of the Preferred Stock (calculated on an as-converted to Common Stock basis) (the “Requisite Holders”); 

WHEREAS, the undersigned represent the Requisite Holders necessary to amend the Investors’ Rights Agreement; and 

WHEREAS, the Company and the Requisite Holders desire to amend certain provisions of the Investors’ Rights Agreement. 

NOW, THEREFORE, in consideration of the mutual promises and covenants contained in this Agreement, the parties hereto, intending to be
legally bound, agree as follows: 
 1. Amendment of Subsection 1.24 of the Investors’ Rights Agreement. Pursuant to
Subsection 6.6 of the Investors’ Rights Agreement, Subsection 1.24 of the Investors’ Rights Agreement is hereby amended and restated in its entirety to read as follows: 

“1.24 “Registrable Securities” means (i) the Common Stock issuable or issued upon conversion of the
Preferred Stock; (ii) any Common Stock issued as (or issuable upon the conversion or exercise of any warrant, right, or other security that is issued as) a dividend or other distribution with respect to, or in exchange for or in replacement of,
the shares referenced in clause (i) above; and (iii) any Common Stock held by Regeneron Pharmaceuticals, Inc. (“Regeneron”); excluding in all cases, however, any Registrable Securities sold by a Person in a transaction in which the
applicable rights under this Agreement are not assigned pursuant to Subsection 6.1, and excluding for purposes of Section 2 any shares for which registration rights have terminated pursuant to Subsection 2.13 of
this Agreement.” 

 2. New Subsection 2.14 of the Investors’ Rights Agreement. Pursuant to
Subsection 6.6 of the Investors’ Rights Agreement, the Investors’ Rights Agreement is hereby amended to add new Subsection 2.14 immediately following Subsection 2.13, which new Subsection 2.14
will read as follows: 
 “2.14 Regeneron Matters. Upon Regeneron’s delivery of an executed counterpart signature
page to this Agreement, and notwithstanding anything to the contrary herein, Regeneron shall be deemed an Investor and, if applicable, a Major Investor hereunder, for all purposes under this Agreement other than for purposes of Sections 3,
4 and 5.” 
 3. Investors’ Rights Agreement. By execution of this Agreement, the Company and the
Requisite Holders executing the same, holding in the aggregate a sufficient number of shares of stock to amend the Investors’ Rights Agreement in accordance with Subsection 6.6 thereof, hereby agree that the provisions
set forth in the Investors’ Rights Agreement are hereby amended as set forth herein. The Investors’ Rights Agreement, as amended by this Agreement, contains the entire agreement among the parties with respect to the subject matter thereof
and hereof and shall be read and construed together as a single agreement. Except to the extent amended hereby, all of the terms, provisions and conditions of the Investors’ Rights Agreement are hereby ratified and confirmed and shall remain in
full force and effect as of the date specified therein. 
 4. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including .pdf) or other transmission method and any
counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. 
 5.
Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement. 

6. Severability. The invalidity or unenforceability of any provision hereof shall in no way affect the validity or

The Parties hereby agree and acknowledge that the Target set forth on Schedule 5.1(e)(iii)(the “[***] Target”) shall be treated as an Intellia Liver Target (including, for clarity, to count as one (1) Regeneron Target towards the
Regeneron Target Cap) for which Regeneron has exercised a Regeneron Option pursuant to Section 5.1(e)[***]. In connection therewith, the Parties shall enter into a Co-Co Agreement for the [***] Target as soon as reasonably practicable following the
Effective Date [***], but in all cases in accordance with Section 5.3. Attached hereto as Schedule 5.1(e)(iii) is Intellia’s development plan and budget for the development of the [***] Target, which shall not be amended without the
mutual agreement of the Parties. Until such time as the Parties enter into a Co-Co Agreement for the [***] Target, Intellia shall use Commercially Reasonable Efforts to conduct, at its cost, the development activities for the [***] Target in
accordance with such development plan and budget, and Intellia shall keep Regeneron reasonably informed in connection with all such activities. Once the Co-Co Agreement is entered into by the Parties for the [***] Target, Regeneron shall reimburse
Intellia for [***] of the development costs incurred by Intellia for the conduct of such activities between the Effective Date and the date of execution of such Co-Co Agreement; provided that such costs shall not exceed the budget mutually
determined by the Parties through the JSC and subject to the terms and conditions of the Co-Co Agreement.

than [***] years from the date that the agreement under which such information is disclosed), to any actual or prospective subcontractor, licensee or sublicensee. Notwithstanding the foregoing or anything to the contrary contained herein, (I)
Regeneron Materials Improvements, Regeneron Product Inventions to the extent solely owned by Regeneron, and [***] and (II) any other Confidential Information to the extent related to Regeneron Products or Regeneron Targets or Regeneron Evaluation
Targets, shall be the Confidential Information of Regeneron, and Intellia Know-How [***], Intellia CRISPR-Cas IP and Intellia Material Improvements shall be the Confidential Information of Intellia. The information in any Option Package
delivered by Intellia shall be the Confidential Information of Intellia and the information in any Option Package delivered by Regeneron shall be the Confidential Information of Regeneron. 

13.2 Exceptions. Notwithstanding Section 13.1, Confidential Information shall not be deemed to include information (and such
information shall not be considered Confidential Information under this Agreement) to the extent that it can be established by written documentation by the Receiving Party that such information: (i) was already in the public domain prior to
time of disclosure by the Disclosing Party or becomes publicly known through no act, omission or fault of the Receiving Party or any Person to whom the Receiving Party provided such information; (ii) is or was already lawfully, and not under an
obligation of confidentiality owed to the Disclosing Party, in the possession of the Receiving Party prior to the time of disclosure by the Disclosing Party; provided that the Receiving Party did not initially generate such information and assign

embraced by general disclosures in the public domain. Further, any combination of Confidential Information will not be considered in the public domain or in the possession of the Receiving Party merely because individual elements of such
Confidential Information are in the public domain or in the possession of the Receiving Party unless the combination and its principles are in the public domain or in the possession of the Receiving Party.

 14.2 Indemnity Procedure. 

(a) Notification. The Party entitled to indemnification under this ARTICLE 14 (an “Indemnified Party”) shall
notify the Party potentially responsible for such indemnification (the “Indemnifying Party”) within [***] Business Days of becoming aware of any Claim asserted or threatened in writing against the Indemnified Party which could give
rise to a right of indemnification under this Agreement; provided, however, that the failure to give such notice shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that such failure materially prejudices the
Indemnifying Party. 
 (b) Control of Defense. If the Indemnifying Party elects in writing to the Indemnified Party that it will
assume control of the defense of such Claim, then except as otherwise set forth in Section 10.9, the Indemnifying Party shall have the right to defend, at its sole cost and expense, such Claim by all appropriate proceedings, which proceedings shall
be prosecuted diligently by the Indemnifying Party to a final conclusion or settled at the discretion of the Indemnifying Party; provided, however, that the Indemnifying Party may not enter into any compromise or settlement unless (i) such
compromise or settlement includes as an unconditional term thereof, the giving by each claimant or plaintiff to the Indemnified Party of a release from all liability in respect of such claim; and (ii) the Indemnified Party consents to such
compromise or settlement, which consent shall not be conditioned, withheld or delayed unless such compromise or settlement involves (A) any admission of legal wrongdoing by the Indemnified Party, (B) any payment by the Indemnified Party that is not
indemnified hereunder or (C) the imposition of any equitable relief against the Indemnified Party. If the Indemnifying Party does not elect to assume control of the defense of such Claim within [***] days of its receipt of notice thereof, or if the
Indemnifying Party elects in writing to the Indemnified Party to cease maintaining control of the defense of such Claim, the Indemnified Party shall have the right, at the expense of the Indemnifying Party, upon at least [***] Business Days’
prior written notice to the Indemnifying Party of its intent to do so, to undertake the defense of such Claim for the account of the Indemnifying Party (with counsel reasonably selected by the Indemnified Party and approved by the Indemnifying
Party, such approval not unreasonably conditioned, withheld or delayed), provided, that the Indemnified Party shall keep the Indemnifying Party apprised of all material developments with respect to such Claim and promptly provide the Indemnifying
Party with copies of all correspondence and documents exchanged by the Indemnified Party and the opposing party(ies) to such Claim. The Indemnified Party may not compromise or settle such Claim without the prior written consent of the
Indemnifying Party, such consent not to be unreasonably conditioned, withheld or delayed. 
 (c) Indemnified Party’s
Participation. The Indemnified Party shall cooperate with the Indemnifying Party in, and may participate in, but not control, any defense or settlement of any Claim controlled by the Indemnifying Party pursuant to this Section 14.2 and
shall bear its own costs and expenses with respect to such participation; provided, however, that the Indemnifying Party shall bear such costs and expenses if counsel for the Indemnifying Party shall have reasonably determined that such counsel may
not properly represent both the Indemnifying Party and the Indemnified Party.

thereafter and for an otherwise longer period as may be required by Applicable Law, each of Regeneron and Intellia will (i) use Commercially Reasonable Efforts to procure and maintain appropriate commercial general liability and product liability
insurance in amounts appropriate for the industry and considering the activities being conducted or (ii) with respect to Regeneron as of the Effective Date, or Intellia as such time as Intellia and its Affiliates have annual revenue in excess of
[***], procure and maintain adequate insurance by means of self-insurance in such amounts and on such terms as are consistent with normal business practices of large pharmaceutical companies in the life sciences industry. Such insurance shall
insure against liability arising from this Agreement on the part of Regeneron or Intellia, respectively, or any of their respective Affiliates, due to injury, disability or death of any person or persons, or property damage arising from activities
performed in connection with this Agreement. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under Section 14.1 or otherwise. Any
insurance proceeds received by a Party in connection with any Damages shall be retained by such Party and shall not reduce any obligation of the other Party. 

ARTICLE 15 
 FORCE
MAJEURE 
 Neither Party will be held liable or responsible to the other Party nor be deemed to have defaulted under or breached this
Agreement for failure or delay in fulfilling or performing any term of this Agreement when such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party including embargoes, acts of terrorism, acts of
war (whether war be declared or not), insurrections, change in Applicable Law, strikes, riots, civil commotions or acts of God (“Force Majeure”). Such excuse from liability and responsibility shall be effective only to the extent
and duration of the event(s) causing the failure or delay in performance and provided that the affected Party has not caused such event(s) to occur. The affected Party will notify the other Party of such Force Majeure circumstances as soon as
reasonably practical and will make every reasonable effort to mitigate the effects of such Force Majeure circumstances. 
 ARTICLE 16

 TERM AND TERMINATION 

16.1 Term. The “Term” of this Agreement shall begin on the Effective Date and will expire on the expiration of the
final Product Term, unless this Agreement is earlier terminated in its entirety in accordance with this ARTICLE 16, in which event the Term shall end on the effective date of such termination. For purposes of this ARTICLE 16, the “Product

 16.2 Termination for Insolvency. A Party shall have the right to terminate this
Agreement in its entirety immediately upon written notice to the other Party if, at any time, (a) the other Party shall file in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency
or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the other Party or of its assets, or (b) if the other Party shall be served with an involuntary petition against it, filed in any insolvency proceeding,
and such petition shall not be dismissed within [***] days after the filing thereof, or (c) if the other Party shall propose or be a party to any dissolution or liquidation proceedings, or (d) if the other Party shall make an assignment for the
benefit of creditors. In the event that this Agreement is terminated or rejected by a Party or its receiver or trustee under applicable bankruptcy laws due to such Party’s bankruptcy, then all rights and licenses granted under or pursuant to
this Agreement by such Party to the other Party are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code and any similar laws in any other country, licenses of rights to “intellectual
property” as defined under Section 101(52) of the U.S. Bankruptcy Code. The Parties agree that all intellectual property rights licensed hereunder, including any Patent Rights in any country of a Party covered by the license grants under
this Agreement, are part of the “intellectual property” as defined under Section 101(35(A)) of the Bankruptcy Code subject to the protections afforded the non-terminating Party under Section 365(n) of the Bankruptcy Code, and any
similar law or regulation in any other country. 
 16.3 Termination of Regeneron Target by Regeneron for
Convenience. At any time, upon [***] days advanced written notice, on a Regeneron Target-by-Regeneron Target basis, Regeneron may terminate this Agreement with respect to such Regeneron Target; provided, that, Regeneron’s obligation to
use Commercially Reasonably Efforts to develop and commercialize Regeneron Products with respect to a given Regeneron Target shall be immediately suspended (and shall be of no further force or effect) following its delivery of such a notice of
termination with respect to such terminated Regeneron Target. For clarity, this Agreement will remain in full force and effect with respect to any other Regeneron Target not terminated. In the event that Regeneron terminates all Regeneron
Targets pursuant to this Section 16.3, then this Agreement shall terminate in its entirety.

 16.4 Breach of the Agreement. 

(a) Either Party may terminate this Agreement in accordance with the remainder of this Section 16.4, either in its entirety or with
respect to the Technology Collaboration or one or more Regeneron Targets, if, as applicable, the other Party commits a material breach of this Agreement (in its entirety or with respect to the Technology Collaboration or with respect to one or more
Regeneron Targets, as applicable), [***] as follows: 
 (i) if such material breach of this Agreement is with respect to the Agreement in
its entirety, then this Agreement may be terminated in its entirety (but only if the material breach affects the entirety of this Agreement); 

(ii) if such material breach of this Agreement is with respect to the Technology Collaboration, then this Agreement may be terminated only
with respect to the Technology Collaboration; or 
 (iii) if such material breach of this Agreement is with respect to one or more
Regeneron Targets, then this Agreement may be terminated only with respect to such Regeneron Target(s). For clarity, when a material breach relates only to certain Regeneron Targets, termination pursuant to this Section 16.4(a)(iii) shall be
solely with respect to the relevant Regeneron Target(s) to which the material breach relates. 
 (b) In the event that one Party (the
“Alleging Party”) believes that the other Party (the “Alleged Party”) has committed a material breach, the Alleging Party shall provide written notice (“Breach Notice”) to the Alleged Party
describing in an appropriate detail the nature of such material breach and whether the Alleging Party proposes to terminate this Agreement pursuant to Section 16.4(a)(i), 16.4(a)(ii), or 16.4(a)(iii). 

(i) The Alleged Party shall have [***] days from its receipt of the Breach Notice to cure such material breach; provided that if such breach
is not curable within the foregoing cure period, then such cure period will be extended for a period of up to [***] additional days (for a total cure period of [***] days) if the Alleged Party prepares and provides to the Alleging Party a reasonable
written plan for curing such breach and uses Commercially Reasonable Efforts to cure such breach in accordance with such written plan. In the event such breach is not cured within such [***] day period, as applicable, this Agreement or portion
thereof, as applicable, may be terminated immediately by the Alleging Party. 
 (c) In the event of a good faith dispute as to the existence
or materiality of a breach specified in such notice, including any good faith dispute as to payments due under this Agreement, and the Alleged Party provides the Alleging Party notice of such dispute within such [***] day period, the cure period
will be tolled from the date the Alleged Party notifies the Alleging Party of such good faith dispute and through the diligent resolution of such dispute in accordance with the applicable provisions of this Agreement (provided that if such dispute
relates to payment, the cure period will only apply with respect to payment of disputed amounts, and not with respect to undisputed amounts). It is understood and agreed that during the pendency of such dispute, all of the terms and conditions of
this Agreement will remain in effect and the Parties will continue to perform all of their respective obligations, and retain their respective rights, hereunder. Termination will become effective, if at all, following a final and conclusive
determination pursuant to Section 17.1 (c)that the Alleged Party committed such material breach and failed to cure the same during the applicable cure period.

 16.5 Termination for IP Challenge. If Regeneron or any of its Affiliates
Challenges an Intellia Background Patent Right or any Patent Rights within the Intellia CRISPR-Cas IP in any country in the world (such Patent Right, a “Challenged Patent Right”), then Intellia may, following written notice to
Regeneron and provided that Regeneron or its Affiliate (and without reference to Section 17.1(b)) does not withdraw such Challenge within [***] days of receipt of such notice, in its sole discretion either (a) exclude such Challenged Patent Right
from the scope of the Patent Rights licensed hereunder or (b) except to the extent the following is unenforceable under the law of a particular jurisdiction where a patent application within the Challenged Patent Rights is pending or a patent within
the Challenged Patent Rights is issued, terminate this Agreement solely with respect to all Regeneron Products Directed to a Regeneron Target that is Covered by such Challenged Patent Right, by providing written notice of termination to
Regeneron. For purposes of this Section 16.5, (i) “Challenge” means[***]. 
 16.6 Termination for Suspension of
Development. 
 (a) On a Regeneron Target-by-Regeneron Target basis, if during the period after selection of such Target as a Regeneron
Target but prior to the First Commercial Sale of a Regeneron Product Directed to such Regeneron Target, Regeneron elects to permanently discontinue the development of all Regeneron Products Directed to such Regeneron Target (other than pursuant
to Section 4.2(b)) it shall provide written notice to Intellia which will automatically be treated as Regeneron’s submission of written notice pursuant to Section 16.3 with respect to such Regeneron Target (a “Discontinuation
Notice”). 
 (b) [***]. 

(c) Within [***] days of Regeneron’s provision of the Discontinuation Notice[***], Intellia may deliver written notice to Regeneron [***]
indicating that that the Agreement be terminated with respect to such Regeneron Target (“Termination for Suspension Notice”). 

(d) If Intellia delivers the Termination for Suspension Notice in accordance with Section 16.6(c) for the applicable Regeneron Target, then
this Agreement shall terminate solely with respect to such Regeneron Target, which termination shall be effective [***] days after the delivery of the Termination for Suspension Notice[***]. If Intellia does not deliver the Termination for
Suspension Notice in accordance with Section 16.6(c) for the applicable Regeneron Target, then this Agreement shall continue in full force and effect with respect to such Regeneron Target.

(e) For clarity, and notwithstanding anything to the contrary herein, this Section 16.6 shall be of no further force or effect, on a Regeneron
Target-by-Regeneron Target basis, from and after the First Commercial Sale of a Regeneron Product Directed to such Regeneron Target.

 16.7 Effects of Termination of Agreement with respect to a given Regeneron Target.
Without limiting any other legal or equitable remedies that either Party may have, if this Agreement is terminated for any reason, then the provisions of this Section 16.7 will apply (but if this Agreement is terminated in part solely with respect
to a Regeneron Target, then this Section 16.7 shall apply only with respect to such Terminated Regeneron Target) (each Regeneron Target that is subject to such termination, a “Terminated Regeneron Target”): 

(a) The licenses granted to the Parties with respect to the Terminated Regeneron Target(s) under Sections [***], as and to the extent
applicable, shall terminate and, as and to the extent applicable, the Product R&D Program pertaining to the Terminated Regeneron Target shall immediately terminate. In addition to the licenses that terminate pursuant to this Section 16.7(a)
above and Section 16.8(a) below, in the event this Agreement is terminated as a whole, the licenses granted to the Parties under Sections [***] shall terminate.

Third Parties and subject to Intellia’s reasonable assistance, transition to Intellia any ongoing clinical trials for Regeneron Products Directed to the Terminated Regeneron Target that are being conducted by Regeneron as of the effective date
of termination, and following such transition, Intellia shall be fully responsible for the conduct of such ongoing clinical trials (provided that, for clarity, the licenses granted to Regeneron hereunder shall survive until such ongoing clinical
trials are so transitioned to Intellia solely to the limited extent necessary to enable Regeneron (and its Affiliates and sublicensees) to continue such clinical trials during such transition period). 

(i) Upon termination of this Agreement, the licenses granted to Regeneron hereunder shall survive for a period of [***] months solely to the
limited extent necessary to enable Regeneron (and its Affiliates and sublicensees) to, at their discretion, during such [***] month period following the effective date of termination, sell-off any Regeneron Products then remaining in its or its

termination for Regeneron’s material breach pursuant to Section 16.4, Intellia shall have no such obligation to reimburse Regeneron hereunder and Regeneron shall be solely responsible for all such costs. 

(k) For clarity, in the event that Intellia does not accept delivery of any of the materials or items that Regeneron is obligated to deliver
under this Section 16.7, or does not provide reasonable assistance with respect thereto, Regeneron shall have no further obligation to undertake any such activities under this Section 16.7. 

(l) In addition, notwithstanding the foregoing provisions of this Section 16.7, in the event of any good faith, inadvertent failure by

such items in order to cure such failure in accordance with the provisions of this Section 16.7, as applicable, as soon as reasonably practicable after receipt of an undisputed written notice thereof from Intellia). All of the foregoing
materials, items and grants provided by Regeneron (or its Affiliates, as applicable) pursuant to this Section 16.7 shall be provided on an “as-is” basis (without any representations or warranties).

Intellia has materially breached this Agreement such that Regeneron would have a right of termination pursuant to Section 16.4 as a result of such material breach (including the application of Section 16.4(b)) [***], then, on a Regeneron
Target-by-Regeneron Target basis to which such material breach relates, in lieu of Regeneron exercising such termination right pursuant to Section 16.4, Regeneron may elect to have this Agreement continue in full force and effect without such
termination (which election shall be made in writing by Regeneron no later than [***] days of such determination thereof); provided, however, that if Regeneron so elects to continue this Agreement in full force and effect without such termination,
then (i) solely with respect to such Regeneron Target for which Intellia has materially breached this Agreement, any milestone payments and royalty payments [***] for Regeneron Products Directed to such Regeneron Target as set forth in Article 9,
that would otherwise be payable by Regeneron hereunder shall, from and after the date of such notice from Regeneron, be reduced by [***] for the remainder of the Term and (ii) solely if clause (i) applies, Regeneron shall not be entitled to seek any
monetary damages against Intellia under a breach of contract or other claim to the extent that such damages arise from or are a result of the material breach giving rise to Regeneron’s termination right [***]. 

16.10 Survival of Obligations. Expiration or termination of this Agreement shall not relieve the Parties of any obligation
accruing prior to such expiration or termination. Any expiration or termination of this Agreement shall be without prejudice to the rights of either Party against the other accrued or accruing under this Agreement prior to expiration or termination.
