Period”) commencing on the earlier of (a) the occurrence of a Change of Control and (b) the first public announcement by the Company of any Change of Control (or pending Change of Control), and ending 60 days following

For so long as the Notes are represented in global form by one or more Global Securities, all payments of principal (and premium, if any) and interest shall be made by wire transfer of immediately available funds to the Depositary or its nominee, as
the case may be, as the registered owner of the Global Security representing such Notes. In the event that definitive Notes shall have been issued, all payments of principal (and premium, if any) and interest shall be made by wire transfer of
immediately available funds to the accounts of the registered Holders thereof; provided, that the Company may elect to make such payments at the office of the Paying Agent in the contiguous United States; and provided further, that the Company may
at its option pay interest by check to the registered address of each Holder of a definitive Note. If an Interest Payment Date falls on a date that is not a Business Day, then interest will be paid on the next day that is a Business Day, and no
interest on such payment will accrue for the period from and after such Interest Payment Date. 
 (e) Currency. The currency of
denomination of the Notes is United States Dollars. Payment of principal of and interest and premium, if any, on the Notes shall be made in United States Dollars. 

(f) Redemption; Sinking Fund. Except as provided in this Article 3, the Company shall have no obligation to redeem, purchase or repay
the Notes pursuant to any mandatory redemption, sinking fund or analogous provisions or at the option of a Holder thereof. 
 (g)
Ranking. The Notes will be senior unsecured obligations of the Company. The payment of the principal of, premium, if any, and interest on the Notes will (i) rank equally in right of payment with all other indebtedness of the Company that
is not by its terms expressly subordinated to other indebtedness of the Company, (ii) rank senior in right of payment to all indebtedness of the Company that is, by its terms, expressly subordinated to the senior indebtedness of the Company and
(iii) be effectively subordinated to the secured indebtedness of the Company to the extent of the value of the collateral securing such indebtedness and to the existing and future liabilities of the Company’s subsidiaries.

Notes to be redeemed that would be due at maturity of such Notes (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year
consisting of twelve 30-day months) at the applicable Treasury Rate plus 10 basis points, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date;

year consisting of twelve 30-day months) at the applicable Treasury Rate plus 10 basis points, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date; 

(iii) with respect to the 2026 Notes, upon redemption prior to the 2026 Par Call Date, the Company shall pay a Redemption Price
equal to the greater of (i) 100% of the principal amount of the 2026 Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the 2026 Notes to be redeemed that would be due at

redeemed, plus accrued and unpaid interest thereon, if any, to, but not including, the Redemption Date.

Certificate of the Company delivered to the Trustee and to Holders of the Notes no later than two Business Days prior to the Redemption Date. The Company may provide in a notice of redemption that payment of such Redemption Price and performance of
the Company’s obligations with respect to such redemption or purchase may be performed by another Person.

 (d) If less than all of the Notes of a particular series are redeemed at any time and the
Notes of such series are Global Notes held by the Depositary, the Depositary will select the Notes to be redeemed in accordance with its operational arrangements. If the Notes are not Global Notes held by the Depositary, the Company will select
Notes called for redemption in part on a pro rata basis or on as nearly a pro rata basis as is practicable; provided that Notes in principal amounts of $2,000 or less shall be redeemed in whole and not in part. In the case of
Notes represented by a Global Security, the outstanding principal amount of the Global Security representing the Notes will be reduced by book-entry. Notes called for redemption become due on the Redemption Date, subject to the satisfaction of any
conditions precedent provided in the notice of redemption. On and after the Redemption Date, interest stops accruing on Notes or portions of them called for redemption (unless there is a default in the payment thereof). 

(e) If a Redemption Date falls on a date that is not a Business Day, then the Redemption Price will be paid on the next day that is a Business
Day, and no interest on such payment will accrue for the period from and after such Redemption Date. 
 Section 3.04. Repurchase of
Notes upon a Change of Control. 
 (a) If a Change of Control Triggering Event occurs with respect to the Notes, unless the Company has
exercised its right to redeem the Notes as provided in Section 3.03 hereof, each Holder of Notes will have the right to require the Company to make an offer (a “Change of Control Offer”) to each Holder of a Note to repurchase
all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes on the terms set forth in this Section 3.04 and in the Notes. In a Change of Control Offer, the Company shall offer payment in
cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of repurchase (a “Change of Control Payment”). Within 30 days following any
Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, the Company shall send a notice to
Holders of the Notes, describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date shall be no earlier than 30 days and no
later than 60 days from the date such notice is sent (a “Change of Control Payment Date”), pursuant to the procedures required by the Notes and described in such notice. The notice shall, if sent prior to the date of consummation of
the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control occurring on or prior to the Change of Control Payment Date. 

(b) On the Change of Control Payment Date, the Company shall, to the extent lawful: 

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the applicable Change of Control Offer;

 (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of
Notes properly tendered; and 
 (iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together
with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased. 

  
 10 

 (c) The Company shall not be required to make a Change of Control Offer with respect to the
Notes upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party purchases all
Notes properly tendered and not withdrawn under its offer. In addition, the Company shall not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a
default in the payment of the Change of Control Payment on the Change of Control Payment Date. 
 (d) The Company shall comply with the
requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the
Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company shall comply with those securities laws
and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict and compliance. 

(e) If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a
Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company, as described in this Section 3.04, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company
shall have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described herein, to redeem all Notes that remain outstanding following
such purchase at a Redemption Price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date (subject to the right of Holders of record on a record date to receive
interest on the relevant Interest Payment Date). 
 Section 3.05. Special Mandatory Redemption. 

(a) If the closing of the FLIR Acquisition has not occurred on or prior to the earlier of (i) December 31, 2021 and (ii) the
date the Merger Agreement, including any amendment thereof, is terminated, according to its terms (each, a “Special Mandatory Redemption Event”), the Company shall redeem the 2023 Notes, the 2024 Notes, the 2026 Notes, and the 2031
Notes in whole at a special mandatory redemption price equal to 101% of the aggregate principal amount of such Notes, plus accrued and unpaid interest on the principal amount of such Notes to but excluding the Special Mandatory Redemption Date (as
defined below) (the “Special Mandatory Redemption Price”). Upon the occurrence of a Special Mandatory Redemption Event, the Company shall promptly (but in no event later than five calendar days following such Special Mandatory
Redemption Event) cause notice to be delivered electronically or mailed, with a copy to the Trustee, to each Holder at its registered address (such date of notification to the Holders, the “Redemption Notice Date”). The notice shall
inform Holders that the Notes will be redeemed on the tenth calendar day (or if such day is not a Business Day, the first Business Day thereafter) following the Redemption Notice Date (such date, the “Special Mandatory Redemption
Date”) and that all of the outstanding Notes to be redeemed shall be redeemed at the Special Mandatory Redemption Price on the Special Mandatory Redemption Date automatically and without any further action by the Holders of the Notes. On
the Business Day immediately preceding the Special Mandatory Redemption Date, the Company shall deposit with the Trustee funds sufficient to pay the Special Mandatory Redemption Price. If such deposit is made as provided above, the Notes to be
redeemed will cease to bear interest on and after the Special Mandatory Redemption Date. 
 (b) Upon the completion of the FLIR Acquisition,
the foregoing provisions regarding special mandatory redemption will cease to apply.

Section 6.01. Consolidation, Merger and Sale of Assets. Solely for the benefit of the Holders of the Notes, Section 8.01 of
the Base Indenture is hereby deleted in its entirety and replaced with the following:

the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of the Notes or any of such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, each Guarantor shall be jointly and severally obligated to pay
the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
 (b) To the maximum
extent permitted under applicable law, the obligations of any Guarantor hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a Guarantor. Subject to Section 5.07 of the Base Indenture, each Guarantor shall waive diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the
Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and
the Indenture. 
 (c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Guarantors or any
custodian, trustee, liquidator or other similar official acting in relation to any of the Company or any Guarantors, any amount paid by any of them to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. 
 (d) No Guarantor shall be entitled to any right of subrogation in relation to the Holders in respect
of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. As between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed
hereby may be accelerated as provided in Article 5 for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event
of any declaration of acceleration of such obligations as provided in Article 5, such obligations (whether or not due and payable) shall forthwith become due and payable by any Guarantors for the purpose of this Guarantee. Any Guarantor that makes a
payment under its Guarantee shall have the right to seek contribution from any non-paying Guarantor, so long as the exercise of such right does not impair the rights of the Holders under the Guarantee. 

Section 7.02. Limitation on Guarantor Liability. 

The maximum aggregate amount guaranteed hereunder by any Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering the
Indenture, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 

Section 7.03. Execution and Delivery of Guarantee. 

(a) To evidence its Guarantee set forth in Section 7.01, each Guarantor agrees that a supplemental indenture substantially in the form
attached hereto as Exhibit F shall be executed on behalf of such Guarantor by one of its Officers. 

  
 18 

 (b) Each Guarantee set forth in Section 7.01 shall remain in full force and effect
notwithstanding any failure to endorse on each Note a notation of such Guarantee. 
 (c) If an Officer whose signature is on any Guarantee no
longer holds that office at the time the Trustee authenticates the Security on which any Guarantee is endorsed, the Guarantee shall be valid nevertheless. 

(d) The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set
forth in the Indenture on behalf of any Guarantor. 
 Section 7.04. Guarantors May Consolidate, etc., on Certain Terms. 

(a) Except as set forth in Section 7.05, a Guarantor may not sell, lease, transfer, convey or otherwise dispose of all or substantially
all of its properties or assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person), another Person, other than the Company or another Guarantor, unless (1) immediately after giving effect to
that transaction, no Default or Event of Default exists and (2) the Person acquiring the property or assets in any such sale, lease, transfer, conveyance or other disposition or the Person formed by or surviving any such consolidation or merger
(if other than the Guarantor) is organized or existing under the laws of the United States, any state thereof or the District of Columbia and assumes all the obligations of that Guarantor under the Indenture and its Guarantee pursuant to a
supplemental indenture satisfactory to the Trustee. 
 (b) In case of any such consolidation, merger, sale, lease, transfer, conveyance or
other disposition governed by Section 7.04(a)(2), upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Guarantee endorsed upon the
Securities and the due and punctual performance of all of the covenants and conditions of the Indenture to be performed by a Guarantor, such successor Person shall succeed to and be substituted for a Guarantor with the same effect as if it had been
named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the
Trustee. All the Guarantees so issued shall in all respects have the same legal rank and benefit under the Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of the Indenture as though all of such Guarantees
had been issued at the date of the execution hereof. 
 Section 7.05. Release of a Guarantor. 

(a) Without prejudice to Section 4.03, any Guarantor shall be automatically released and relieved of any obligations under its Guarantee,
(i) in connection with any sale or other disposition of all of the capital stock of such Guarantor, or all or substantially all of such Guarantor’s assets, to a Person that is not (either before or after giving effect to such transaction)
the Company or a Domestic Subsidiary of the Company required to deliver a Guarantee under Section 4.03; (ii) upon Legal Defeasance or Covenant Defeasance (as defined below) as permitted under the Indenture; or (iii) upon release or
discharge of all guarantees by such Guarantor of all other indebtedness of the Company, except a discharge or release by or as a result of payment under such guarantees of other indebtedness of the Company. Notwithstanding the foregoing, the Company
shall not, directly or indirectly, sell or make any other disposition of all of the capital stock of any Guarantor or of all or substantially all of any Guarantor’s assets to a Person that is not a Domestic Subsidiary solely for the purpose of
causing such Guarantor to be released from its Guarantee. 

  
 19 

 (b) Upon delivery by the Company to the Trustee of an Officer’s Certificate to the
effect that one of the foregoing requirements has been satisfied and the conditions to the release of a Guarantor under this Section 7.05 have been met, the Trustee shall execute any documents reasonably required in order to evidence the
release of such Guarantor from its obligations under its Guarantee. Any Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal of, premium, if any, and interest on the Securities as
provided in this Article 7. 
 ARTICLE 8 

AMENDMENT AND WAIVER 

Solely for the benefit of the Holders of the Notes, Section 9.02 of the Base Indenture is hereby deleted in its entirety and replaced
with the following: 
 Section 8.01. “Section 9.02. Supplemental Indentures With Consent of
Holders. 
 (a) The Company and the Trustee may enter into one or more supplemental indentures to add to, change or eliminate any of the
provisions of this Indenture in respect of the Securities of a series with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Securities of such series (including consents obtained in connection with a
tender offer or exchange offer for such Securities). Any past default or compliance with any provisions of this Indenture with respect to Securities of a series may be waived (except a default in the payment of principal, premium or interest and
except as provided in Section 9.02(b)) with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Securities of such series. 

(b) However, without the consent of each Holder of an outstanding Security of the affected series, no amendment may:

(ii) reduce the principal amount of, or any premium or interest rate on, any Security; 

(iii) change the place or currency of payment of principal of, or any premium or interest on any Security; 

(iv) impair the right to institute suit for the enforcement of any payment on or with respect to any Security; or 

(v) reduce the percentage in principal amount of the then outstanding the Securities, the consent of whose holders is required
for modification or amendment of this Indenture, for waiver of compliance with certain provisions of this Indenture or for waiver of certain defaults. 

(c) The consent of the Holders of the Securities shall not be necessary to approve the particular form of any proposed amendment. It shall be
sufficient if such consent approves the substance of the proposed amendment. 
 (d) After an amendment that requires the consent of the
Holders of the affected Securities becomes effective, the Company shall mail (or send electronically) to each Holder of the affected Securities at such Holder’s address appearing in the register maintained by the Registrar pursuant to
Section 3.05 a notice briefly describing such amendment. However, the failure to give such notice to all Holders of such Securities, or any defect therein, shall not impair or affect the validity of the amendment. 

  
 20 

 (e) Upon the written request of the Company accompanied by a Board Resolution authorizing
the execution of any such supplemental indenture, and upon the receipt by the Trustee of evidence reasonably satisfactory to the Trustee of the consent of the Holders as aforesaid and upon receipt by the Trustee of the documents described in
Section 9.03, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture, in which case the Trustee
may, but shall not be obligated to, enter into such supplemental indenture.” 
 ARTICLE 9 

DEFEASANCE 

Section 9.01. Defeasance. Subject to Section 13.04 of the Base Indenture, the Company may at any time elect to terminate its
obligations with respect to the Notes (hereinafter, “Legal Defeasance”) except for obligations under Sections 3.05 and 3.06 of the Base Indenture and obligations under the TIA on a date the applicable conditions set forth in
Section 13.04 of the Base Indenture are satisfied. If the Company exercises its Legal Defeasance option with respect to the Notes, payments of the Notes may not be accelerated because of an Event of Default with respect thereto. The Company may
terminate its obligations with respect to the Notes under Sections 4.01, 4.02 and 4.03 of this First Supplemental Indenture and Section 7.04 of the Base Indenture on a date the applicable conditions set forth in Section 13.04 of the Base
Indenture are satisfied (hereinafter, “Covenant Defeasance”) and thereafter, any failure to comply with any of Section 4.01, 4.02 or 4.03 of this First Supplemental Indenture or Section 7.04 of the Base Indenture will not
constitute a Default or an Event of Default with respect to the Notes. The Company may exercise its Legal Defeasance option with respect to the Notes notwithstanding its prior exercise of its Covenant Defeasance option with respect to the Notes.

 TELEDYNE TECHNOLOGIES INCORPORATED 

0.650% NOTE DUE 2023 
 1.
Interest. Teledyne Technologies Incorporated, a Delaware corporation, as issuer (the “Company”), promises to pay, until the principal hereof is paid or made available for payment, interest on the principal amount set forth on
the face hereof at a rate of 0.650% per annum. Interest hereon will accrue from and including the most recent date to which interest has been paid or, if no interest has been paid, from and including March 22, 2021 to, but excluding, the date
on which interest is paid. Interest shall be payable in arrears on April 1 and October 1 of each year, commencing October 1, 2021. Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months. The Company shall pay interest on overdue principal and on overdue interest (to the full extent permitted by law) at the rate borne by the Notes. 

2. Method of Payment. The Company will pay interest hereon (except defaulted interest) to the Persons who are registered Holders at the
close of business on the March 15 and September 15 immediately preceding the interest payment date (whether or not a Business Day). Holders do not have to surrender Notes to a Paying Agent to collect principal payments. The Company will
pay to the Paying Agent principal and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. If a Holder has given wire transfer instructions to the Company, the Company
will pay, or cause to be paid by the Paying Agent, all principal (and premium, if any) and interest on that Holder’s Notes in accordance with those instructions. All other payments on the Notes will be made at the office or agency of the Paying
Agent and Registrar unless the Company elects to make interest payments by check mailed to the Holders at their address set forth in the register of Holders. 

3. Paying Agent and Registrar. Initially, U.S. Bank National Association (the “Trustee”) will act as a Paying Agent and
Security Registrar. The Company may change any Paying Agent or Security Registrar without notice to the Holders. The Company or any of its Subsidiaries may act as Paying Agent or Security Registrar. 

4. Indenture. This Note is one of the series designated on the face hereof. This Note is one of a duly authorized issue of securities of
the Company issued and to be issued in one or more series under an Indenture, dated as of March 22, 2021 (the “Base Indenture”), between the Company and the Trustee, as supplemented by the First Supplemental Indenture, dated as
of March 22, 2021 (the “Supplemental Indenture” and, together with the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”). This is one of an issue of Notes of the Company issued, or
to be issued, under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb), as amended from time to
time (the “Trust Indenture Act”). The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of them. Capitalized and certain other terms used herein and not
otherwise defined have the meanings set forth in the Indenture. 
 5. Optional Redemption; Special Mandatory Redemption. The Notes of
this series are subject to redemption at any time or from time to time, prior to April 1, 2023, in whole or in part, at the Company’s option at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Notes to be
redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed that would be due at maturity of such Notes (exclusive of interest accrued to the Redemption Date)
discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 10 basis
points, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date. The Company may provide in such notice that payment of such price and performance of the Company’s obligations with respect to such redemption or purchase
may be performed by another Person. Any such notice may, at the Company’s discretion, be subject to the satisfaction of one or more conditions precedent. In addition, the Notes may be subject to special mandatory redemption as further described
in the First Supplemental Indenture. 

  
 A-5 

 Any notice to holders of Notes of a redemption pursuant to this paragraph 5 will include the appropriate
calculation of the Redemption Price, but does not need to include the Redemption Price itself. The actual Redemption Price, calculated as described above, will be set forth in an Officer’s Certificate of the Company delivered to the Trustee no
later than two Business Days prior to the Redemption Date. 
 6. Redemption Procedures. The Company will select Notes called for
redemption in part pursuant to paragraph 5 on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to procedures of the Depositary); provided that Notes in principal amount of $2,000 or less shall be
redeemed in whole and not in part. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note, or in the case of Notes represented by a Global
Security, the outstanding principal amount of such Global Security will be reduced by book-entry. Notes called for redemption pursuant to paragraph 5 become due on the Redemption Date. On and after the Redemption Date, interest stops accruing on
Notes or portions of them called for redemption (unless there is a default in the payment thereof). 
 7. Notice of Redemption.
Notices of redemption pursuant to paragraph 5 shall be mailed by first class mail (or sent electronically) at least 10 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address with a copy
to the Trustee. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. 

8. Change of Control. Upon the occurrence of a Change of Control Triggering Event, unless all Notes have been called for redemption
pursuant to paragraph 5, each Holder of Notes of this series shall have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Notes at an offer price in cash
equal to the Change of Control Payment. The Change of Control Offer will be made in accordance with the terms specified in the Indenture. 

9. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral
multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay to it any
taxes and fees required by law or permitted by the Indenture. 
 10. Persons Deemed Owners. The registered Holder of this Note may be
treated as the owner of this Note for all purposes. 
 11. Unclaimed Money. If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an “abandoned
property” law designates another Person. 
 12. Amendment, Waiver, Etc. The Company and the Trustee (if a party thereto) may,
without the consent of the Holders of any outstanding Notes, amend or waive the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or inconsistencies, maintaining the qualification of
the Indenture under the Trust Indenture Act, providing for the assumption by a successor to the Company of its obligations under the Indenture and making any change that does not adversely affect the rights of any Holder in any material respect.
Other amendments of the Indenture or the Notes may be made by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount of the outstanding Notes, subject to certain exceptions requiring
the consent of the Holders of the particular Notes to be affected. 

  
 A-6 

 13. Successor Corporation. When a successor corporation assumes all the obligations
of its predecessor under the Notes and the Indenture and the transaction complies with the terms of Article 6 of the Supplemental Indenture, the predecessor corporation will, except as provided in Article 6 of the Supplemental Indenture, be released
from those obligations. 
 14. Defaults and Remedies. Events of Default are set forth in the Supplemental Indenture. Subject to
certain limitations in the Indenture, if an Event of Default (other than an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture) occurs and is continuing, then, and in each and every such case, either the
Trustee, by notice in writing to the Company, or the Holders of not less than 25% of the principal amount of the Notes then outstanding, by notice in writing to the Company and the Trustee, may, and the Trustee at the request of such Holders shall,
declare due and payable, if not already due and payable, the principal of and any accrued and unpaid interest on all of the Notes; and upon any such declaration all such amounts upon such Notes shall become and be immediately due and payable,
anything in the Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture occurs, then the principal of and any accrued and unpaid interest on all of the
Notes shall immediately become due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require security or
indemnity satisfactory to it in its sole discretion before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any
trust or power, provided, that the Trustee will be entitled to refuse to follow any such direction that conflicts with law or the Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other Holders or could,
in reasonable likelihood, impose personal liability upon the Trustee, unless the Trustee is offered, and if requested, provided indemnity satisfactory to it. The Trustee may withhold from Holders notice of any continuing default (except a default in
payment of principal, premium, if any, or interest on the Notes) if it determines that withholding notice is in their best interests. 
 15.
Trustee Dealings with Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee, in its individual or any other capacity, may make loans to, accept deposits from, perform services for or otherwise deal with the
Company or any Affiliate thereof, with the same rights it would have as if it were not Trustee. 
 16. No Recourse Against Others. No
past, present or future director, officer, employee, incorporator, agent, member or stockholder or Affiliate of the Company, as such, shall have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based
on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liabilities. The waiver and release are part of the consideration for issuance of the Notes. 

17. Discharge; Defeasance. The Company’s obligations pursuant to the Indenture will be discharged, except for obligations
pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the Notes or upon the irrevocable deposit with the Trustee of United States dollars or Government Obligations sufficient to pay when due principal
of and interest on the Notes to maturity or redemption. 
 The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness
of the Company on this Note and (b) certain restrictive covenants and the related Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note. 

  
 A-7 

 18. Guarantee. As more fully set forth in the First Supplemental Indenture, the
Company’s obligations under the Notes shall be guaranteed, under certain circumstances, by certain Domestic Subsidiaries of the Company that execute a supplemental indenture in accordance with the Supplemental Indenture. 

19. Authentication. This Note shall not be valid until the Trustee signs the certificate of authentication on the other side of this
Security. 
 20. Governing Law. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

 21. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in
common), TENANT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

 TELEDYNE TECHNOLOGIES INCORPORATED 

0.950% NOTE DUE 2024 
 1.
Interest. Teledyne Technologies Incorporated, a Delaware corporation, as issuer (the “Company”), promises to pay, until the principal hereof is paid or made available for payment, interest on the principal amount set forth on
the face hereof at a rate of 0.950% per annum. Interest hereon will accrue from and including the most recent date to which interest has been paid or, if no interest has been paid, from and including March 22, 2021 to, but excluding, the date
on which interest is paid. Interest shall be payable in arrears on April 1 and October 1 of each year, commencing October 1, 2021. Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months. The Company shall pay interest on overdue principal and on overdue interest (to the full extent permitted by law) at the rate borne by the Notes. 

2. Method of Payment. The Company will pay interest hereon (except defaulted interest) to the Persons who are registered Holders at the
close of business on the March 15 and September 15 immediately preceding the interest payment date (whether or not a Business Day). Holders do not have to surrender Notes to a Paying Agent to collect principal payments. The Company will
pay to the Paying Agent principal and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. If a Holder has given wire transfer instructions to the Company, the Company
will pay, or cause to be paid by the Paying Agent, all principal (and premium, if any) and interest on that Holder’s Notes in accordance with those instructions. All other payments on the Notes will be made at the office or agency of the Paying
Agent and Registrar unless the Company elects to make interest payments by check mailed to the Holders at their address set forth in the register of Holders. 

3. Paying Agent and Registrar. Initially, U.S. Bank National Association (the “Trustee”) will act as a Paying Agent and
Security Registrar. The Company may change any Paying Agent or Security Registrar without notice to the Holders. The Company or any of its Subsidiaries may act as Paying Agent or Security Registrar. 

4. Indenture. This Note is one of the series designated on the face hereof. This Note is one of a duly authorized issue of securities of
the Company issued and to be issued in one or more series under an Indenture, dated as of March 22, 2021 (the “Base Indenture”), between the Company and the Trustee, as supplemented by the First Supplemental Indenture, dated as
of March 22, 2021 (the “Supplemental Indenture” and, together with the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”). This is one of an issue of Notes of the Company issued, or
to be issued, under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb), as amended from time to
time (the “Trust Indenture Act”). The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of them. Capitalized and certain other terms used herein and not
otherwise defined have the meanings set forth in the Indenture. 
 5. Optional Redemption; Special Mandatory Redemption. The Notes of
this series are subject to redemption at any time or from time to time, prior to April 1, 2022, in whole or in part, at the Company’s option at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Notes to be
redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed that would be due at maturity of such Notes (exclusive of interest accrued to the Redemption Date)
discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 10 basis
points, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date. In addition, the Notes are subject to redemption at any time or from time to time, in whole or in part, at the Company’s option, from and after
April 1, 2022, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest, if any, on such 

  
 B-5 

 
Notes to, but excluding, the Redemption Date. The Company may provide in such notice that payment of such price and performance of the Company’s obligations with respect to such redemption
or purchase may be performed by another Person. Any such notice may, at the Company’s discretion, be subject to the satisfaction of one or more conditions precedent. In addition, the Notes may be subject to special mandatory redemption as
further described in the First Supplemental Indenture. 
 Any notice to holders of Notes of a redemption pursuant to this paragraph 5 will include the
appropriate calculation of the Redemption Price, but does not need to include the Redemption Price itself. The actual Redemption Price, calculated as described above, will be set forth in an Officer’s Certificate of the Company delivered to the
Trustee no later than two Business Days prior to the Redemption Date. 
 6. Redemption Procedures. The Company will select Notes
called for redemption in part pursuant to paragraph 5 on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to procedures of the Depositary); provided that Notes in principal amount of $2,000 or less
shall be redeemed in whole and not in part. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note, or in the case of Notes represented by a
Global Security, the outstanding principal amount of such Global Security will be reduced by book-entry. Notes called for redemption pursuant to paragraph 5 become due on the Redemption Date. On and after the Redemption Date, interest stops accruing
on Notes or portions of them called for redemption (unless there is a default in the payment thereof). 
 7. Notice of Redemption.
Notices of redemption pursuant to paragraph 5 shall be mailed by first class mail (or sent electronically) at least 10 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address with a copy
to the Trustee. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. 

8. Change of Control. Upon the occurrence of a Change of Control Triggering Event, unless all Notes have been called for redemption
pursuant to paragraph 5, each Holder of Notes of this series shall have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Notes at an offer price in cash
equal to the Change of Control Payment. The Change of Control Offer will be made in accordance with the terms specified in the Indenture. 

9. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral
multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay to it any
taxes and fees required by law or permitted by the Indenture. 
 10. Persons Deemed Owners. The registered Holder of this Note may be
treated as the owner of this Note for all purposes. 
 11. Unclaimed Money. If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an “abandoned
property” law designates another Person. 
 12. Amendment, Waiver, Etc. The Company and the Trustee (if a party thereto) may,
without the consent of the Holders of any outstanding Notes, amend or waive the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or inconsistencies, maintaining the qualification of
the Indenture under the Trust Indenture Act, providing for the assumption by a successor to the 

  
 B-6 

 
Company of its obligations under the Indenture and making any change that does not adversely affect the rights of any Holder in any material respect. Other amendments of the Indenture or the
Notes may be made by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount of the outstanding Notes, subject to certain exceptions requiring the consent of the Holders of the
particular Notes to be affected. 
 13. Successor Corporation. When a successor corporation assumes all the obligations of its
predecessor under the Notes and the Indenture and the transaction complies with the terms of Article 6 of the Supplemental Indenture, the predecessor corporation will, except as provided in Article 6 of the Supplemental Indenture, be released from
those obligations. 
 14. Defaults and Remedies. Events of Default are set forth in the Supplemental Indenture. Subject to certain
limitations in the Indenture, if an Event of Default (other than an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture) occurs and is continuing, then, and in each and every such case, either the Trustee, by
notice in writing to the Company, or the Holders of not less than 25% of the principal amount of the Notes then outstanding, by notice in writing to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare due
and payable, if not already due and payable, the principal of and any accrued and unpaid interest on all of the Notes; and upon any such declaration all such amounts upon such Notes shall become and be immediately due and payable, anything in the
Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture occurs, then the principal of and any accrued and unpaid interest on all of the Notes shall
immediately become due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require security or indemnity
satisfactory to it in its sole discretion before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or
power, provided, that the Trustee will be entitled to refuse to follow any such direction that conflicts with law or the Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other Holders or could, in
reasonable likelihood, impose personal liability upon the Trustee, unless the Trustee is offered, and if requested, provided indemnity satisfactory to it. The Trustee may withhold from Holders notice of any continuing default (except a default in
payment of principal, premium, if any, or interest on the Notes) if it determines that withholding notice is in their best interests. 
 15.
Trustee Dealings with Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee, in its individual or any other capacity, may make loans to, accept deposits from, perform services for or otherwise deal with the
Company or any Affiliate thereof, with the same rights it would have as if it were not Trustee. 
 16. No Recourse Against Others. No
past, present or future director, officer, employee, incorporator, agent, member or stockholder or Affiliate of the Company, as such, shall have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based
on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liabilities. The waiver and release are part of the consideration for issuance of the Notes. 

17. Discharge; Defeasance. The Company’s obligations pursuant to the Indenture will be discharged, except for obligations
pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the Notes or upon the irrevocable deposit with the Trustee of United States dollars or Government Obligations sufficient to pay when due principal
of and interest on the Notes to maturity or redemption. 

  
 B-7

Company on this Note and (b) certain restrictive covenants and the related Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note. 

18. Guarantee. As more fully set forth in the First Supplemental Indenture, the Company’s obligations under the Notes shall be
guaranteed, under certain circumstances, by certain Domestic Subsidiaries of the Company that execute a supplemental indenture in accordance with the Supplemental Indenture.

Security.

notice in writing to the Company, or the Holders of not less than 25% of the principal amount of the Notes then outstanding, by notice in writing to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare due
and payable, if not already due and payable, the principal of and any accrued and unpaid interest on all of the Notes; and upon any such declaration all such amounts upon such Notes shall become and be immediately due and payable, anything in the
Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture occurs, then the principal of and any accrued and unpaid interest on all of the Notes shall
immediately become due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require security or indemnity
satisfactory to it in its sole discretion before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or
power, provided, that the Trustee will be entitled to refuse to follow any such direction that conflicts with law or the Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other Holders or could, in
reasonable likelihood, impose personal liability upon the Trustee, unless the Trustee is offered, and if requested, provided indemnity satisfactory to it. The Trustee may withhold from Holders notice of any continuing default (except a default in
payment of principal, premium, if any, or interest on the Notes) if it determines that withholding notice is in their best interests. 
 15.
Trustee Dealings with Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee, in its individual or any other capacity, may make loans to, accept deposits from, perform services for or otherwise deal with the
Company or any Affiliate thereof, with the same rights it would have as if it were not Trustee. 
 16. No Recourse Against Others. No
past, present or future director, officer, employee, incorporator, agent, member or stockholder or Affiliate of the Company, as such, shall have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based
on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liabilities. The waiver and release are part of the consideration for issuance of the Notes. 

17. Discharge; Defeasance. The Company’s obligations pursuant to the Indenture will be discharged, except for obligations
pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the Notes or upon the irrevocable deposit with the Trustee of United States dollars or Government Obligations sufficient to pay when due principal
of and interest on the Notes to maturity or redemption.

 TELEDYNE TECHNOLOGIES INCORPORATED 

2.250% NOTE DUE 2028 
 1.
Interest. Teledyne Technologies Incorporated, a Delaware corporation, as issuer (the “Company”), promises to pay, until the principal hereof is paid or made available for payment, interest on the principal amount set forth on
the face hereof at a rate of 2.250% per annum. Interest hereon will accrue from and including the most recent date to which interest has been paid or, if no interest has been paid, from and including March 22, 2021 to, but excluding, the date
on which interest is paid. Interest shall be payable in arrears on April 1 and October 1 of each year, commencing October 1, 2021. Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months. The Company shall pay interest on overdue principal and on overdue interest (to the full extent permitted by law) at the rate borne by the Notes. 

2. Method of Payment. The Company will pay interest hereon (except defaulted interest) to the Persons who are registered Holders at the
close of business on the March 15 and September 15 immediately preceding the interest payment date (whether or not a Business Day). Holders do not have to surrender Notes to a Paying Agent to collect principal payments. The Company will
pay to the Paying Agent principal and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. If a Holder has given wire transfer instructions to the Company, the Company
will pay, or cause to be paid by the Paying Agent, all principal (and premium, if any) and interest on that Holder’s Notes in accordance with those instructions. All other payments on the Notes will be made at the office or agency of the Paying
Agent and Registrar unless the Company elects to make interest payments by check mailed to the Holders at their address set forth in the register of Holders. 

3. Paying Agent and Registrar. Initially, U.S. Bank National Association (the “Trustee”) will act as a Paying Agent and
Security Registrar. The Company may change any Paying Agent or Security Registrar without notice to the Holders. The Company or any of its Subsidiaries may act as Paying Agent or Security Registrar. 

4. Indenture. This Note is one of the series designated on the face hereof. This Note is one of a duly authorized issue of securities of
the Company issued and to be issued in one or more series under an Indenture, dated as of March 22, 2021 (the “Base Indenture”), between the Company and the Trustee, as supplemented by the First Supplemental Indenture, dated as
of March 22, 2021 (the “Supplemental Indenture” and, together with the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”). This is one of an issue of Notes of the Company issued, or
to be issued, under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb), as amended from time to
time (the “Trust Indenture Act”). The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of them. Capitalized and certain other terms used herein and not
otherwise defined have the meanings set forth in the Indenture. 
 5. Optional Redemption. The Notes of this series are subject to
redemption at any time or from time to time, prior to February 1, 2028, in whole or in part, at the Company’s option at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed and
(ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed that would be due at maturity of such Notes (exclusive of interest accrued to the Redemption Date) discounted to the
Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 15 basis points, plus accrued
and unpaid interest thereon to, but excluding, the Redemption Date. In addition, the Notes are subject to redemption at any time or from time to time, in whole or in part, at the Company’s option, from and after February 1, 2028, at a
redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest, if any, on such Notes to, but excluding, 

  
 D-5 

 
the Redemption Date. The Company may provide in such notice that payment of such price and performance of the Company’s obligations with respect to such redemption or purchase may be
performed by another Person. Any such notice may, at the Company’s discretion, be subject to the satisfaction of one or more conditions precedent. 

Any notice to holders of Notes of a redemption pursuant to this paragraph 5 will include the appropriate calculation of the Redemption Price, but does not
need to include the Redemption Price itself. The actual Redemption Price, calculated as described above, will be set forth in an Officer’s Certificate of the Company delivered to the Trustee no later than two Business Days prior to the
Redemption Date. 
 6. Redemption Procedures. The Company will select Notes called for redemption in part pursuant to paragraph 5 on a
pro rata basis or on as nearly a pro rata basis as is practicable (subject to procedures of the Depositary); provided that Notes in principal amount of $2,000 or less shall be redeemed in whole and not in part. A new Note in
principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note, or in the case of Notes represented by a Global Security, the outstanding principal amount of such
Global Security will be reduced by book-entry. Notes called for redemption pursuant to paragraph 5 become due on the Redemption Date. On and after the Redemption Date, interest stops accruing on Notes or portions of them called for redemption
(unless there is a default in the payment thereof). 
 7. Notice of Redemption. Notices of redemption pursuant to paragraph 5 shall be
mailed by first class mail (or sent electronically) at least 10 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address with a copy to the Trustee. If any Note is to be redeemed in part
only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. 
 8.
Change of Control. Upon the occurrence of a Change of Control Triggering Event, unless all Notes have been called for redemption pursuant to paragraph 5, each Holder of Notes of this series shall have the right to require the Company to
repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Notes at an offer price in cash equal to the Change of Control Payment. The Change of Control Offer will be made in accordance with the terms
specified in the Indenture. 
 9. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum
denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and to pay to it any taxes and fees required by law or permitted by the Indenture. 
 10. Persons Deemed Owners.
The registered Holder of this Note may be treated as the owner of this Note for all purposes. 
 11. Unclaimed Money. If money for the
payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment as general
creditors unless an “abandoned property” law designates another Person. 
 12. Amendment, Waiver, Etc. The Company and the
Trustee (if a party thereto) may, without the consent of the Holders of any outstanding Notes, amend or waive the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or inconsistencies,
maintaining the qualification of the Indenture under the Trust Indenture Act, providing for the assumption by a successor to the Company of its obligations under the Indenture and making any change that does not adversely affect the rights

  
 D-6 

 
of any Holder in any material respect. Other amendments of the Indenture or the Notes may be made by the Company and the Trustee with the consent of the Holders of not less than a majority of the
aggregate principal amount of the outstanding Notes, subject to certain exceptions requiring the consent of the Holders of the particular Notes to be affected. 

13. Successor Corporation. When a successor corporation assumes all the obligations of its predecessor under the Notes and the Indenture
and the transaction complies with the terms of Article 6 of the Supplemental Indenture, the predecessor corporation will, except as provided in Article 6 of the Supplemental Indenture, be released from those obligations. 

14. Defaults and Remedies. Events of Default are set forth in the Supplemental Indenture. Subject to certain limitations in the
Indenture, if an Event of Default (other than an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture) occurs and is continuing, then, and in each and every such case, either the Trustee, by notice in writing to
the Company, or the Holders of not less than 25% of the principal amount of the Notes then outstanding, by notice in writing to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare due and payable, if not
already due and payable, the principal of and any accrued and unpaid interest on all of the Notes; and upon any such declaration all such amounts upon such Notes shall become and be immediately due and payable, anything in the Indenture or in the
Notes to the contrary notwithstanding. If an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture occurs, then the principal of and any accrued and unpaid interest on all of the Notes shall immediately become due
and payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require security or indemnity satisfactory to it in
its sole discretion before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power, provided, that
the Trustee will be entitled to refuse to follow any such direction that conflicts with law or the Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other Holders or could, in reasonable likelihood, impose
personal liability upon the Trustee, unless the Trustee is offered, and if requested, provided indemnity satisfactory to it. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal, premium,
if any, or interest on the Notes) if it determines that withholding notice is in their best interests. 
 15. Trustee Dealings with
Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee, in its individual or any other capacity, may make loans to, accept deposits from, perform services for or otherwise deal with the Company or any Affiliate
thereof, with the same rights it would have as if it were not Trustee. 
 16. No Recourse Against Others. No past, present or future
director, officer, employee, incorporator, agent, member or stockholder or Affiliate of the Company, as such, shall have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liabilities. The waiver and release are part of the consideration for issuance of the Notes. 

17. Discharge; Defeasance. The Company’s obligations pursuant to the Indenture will be discharged, except for obligations
pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the Notes or upon the irrevocable deposit with the Trustee of United States dollars or Government Obligations sufficient to pay when due principal
of and interest on the Notes to maturity or redemption. 
 The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness
of the Company on this Note and (b) certain restrictive covenants and the related Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note.

interest stops accruing on Notes or portions of them called for redemption (unless there is a default in the payment thereof). 
 7.
Notice of Redemption. Notices of redemption pursuant to paragraph 5 shall be mailed by first class mail (or sent electronically) at least 10 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its
registered address with a copy to the Trustee. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. 

8. Change of Control. Upon the occurrence of a Change of Control Triggering Event, unless all Notes have been called for redemption
pursuant to paragraph 5, each Holder of Notes of this series shall have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Notes at an offer price in cash
equal to the Change of Control Payment. The Change of Control Offer will be made in accordance with the terms specified in the Indenture. 

9. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral
multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay to it any
taxes and fees required by law or permitted by the Indenture. 
 10. Persons Deemed Owners. The registered Holder of this Note may be
treated as the owner of this Note for all purposes. 
 11. Unclaimed Money. If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an “abandoned
property” law designates another Person. 
 12. Amendment, Waiver, Etc. The Company and the Trustee (if a party thereto) may,
without the consent of the Holders of any outstanding Notes, amend or waive the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or inconsistencies, maintaining the qualification of
the Indenture under the Trust Indenture Act, providing for the assumption by a successor to the 

  
 E-6 

 
Company of its obligations under the Indenture and making any change that does not adversely affect the rights of any Holder in any material respect. Other amendments of the Indenture or the
Notes may be made by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount of the outstanding Notes, subject to certain exceptions requiring the consent of the Holders of the
particular Notes to be affected. 
 13. Successor Corporation. When a successor corporation assumes all the obligations of its
predecessor under the Notes and the Indenture and the transaction complies with the terms of Article 6 of the Supplemental Indenture, the predecessor corporation will, except as provided in Article 6 of the Supplemental Indenture, be released from
those obligations. 
 14. Defaults and Remedies. Events of Default are set forth in the Supplemental Indenture. Subject to certain
limitations in the Indenture, if an Event of Default (other than an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture) occurs and is continuing, then, and in each and every such case, either the Trustee, by
notice in writing to the Company, or the Holders of not less than 25% of the principal amount of the Notes then outstanding, by notice in writing to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare due
and payable, if not already due and payable, the principal of and any accrued and unpaid interest on all of the Notes; and upon any such declaration all such amounts upon such Notes shall become and be immediately due and payable, anything in the
Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Sections 5.01(e) and 5.01(f) of the Supplemental Indenture occurs, then the principal of and any accrued and unpaid interest on all of the Notes shall
immediately become due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require security or indemnity
satisfactory to it in its sole discretion before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or
power, provided, that the Trustee will be entitled to refuse to follow any such direction that conflicts with law or the Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other Holders or could, in
reasonable likelihood, impose personal liability upon the Trustee, unless the Trustee is offered, and if requested, provided indemnity satisfactory to it. The Trustee may withhold from Holders notice of any continuing default (except a default in
payment of principal, premium, if any, or interest on the Notes) if it determines that withholding notice is in their best interests. 
 15.
Trustee Dealings with Company. Subject to certain limitations imposed by the Trust Indenture Act, the Trustee, in its individual or any other capacity, may make loans to, accept deposits from, perform services for or otherwise deal with the
Company or any Affiliate thereof, with the same rights it would have as if it were not Trustee. 
 16. No Recourse Against Others. No
past, present or future director, officer, employee, incorporator, agent, member or stockholder or Affiliate of the Company, as such, shall have any liability for any obligations of the Company under the Notes, the Indenture or for any claim based
on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liabilities. The waiver and release are part of the consideration for issuance of the Notes. 

17. Discharge; Defeasance. The Company’s obligations pursuant to the Indenture will be discharged, except for obligations
pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the Notes or upon the irrevocable deposit with the Trustee of United States dollars or Government Obligations sufficient to pay when due principal
of and interest on the Notes to maturity or redemption. 

  
 E-7 

 The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness of the
Company on this Note and (b) certain restrictive covenants and the related Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note. 

18. Guarantee. As more fully set forth in the First Supplemental Indenture, the Company’s obligations under the Notes shall be
guaranteed, under certain circumstances, by certain Domestic Subsidiaries of the Company that execute a supplemental indenture in accordance with the Supplemental Indenture. 

19. Authentication. This Note shall not be valid until the Trustee signs the certificate of authentication on the other side of this
Security. 
 20. Governing Law. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

WHEREAS, Teledyne Technologies Incorporated, a Delaware corporation (the “Company”), has executed and delivered to the
Trustee an Indenture, dated as of March 22, 2021 (the “Indenture”), as supplemented by the First Supplemental Indenture thereto, dated as of March 22, 2021 (the “First Supplemental Indenture”), providing

WHEREAS, the Indenture provides that, under certain circumstances, the Guarantor shall execute and deliver to the Trustee a
supplemental indenture pursuant to which the Guarantor shall unconditionally guarantee all of the Company’s obligations under the Securities and the Indenture on the terms and conditions set forth herein; 

WHEREAS, all things necessary to make this Supplemental Indenture a valid agreement of the Guarantor and the Trustee, in accordance
with its terms, and a valid amendment of, and supplement to, the Indenture have been done; 
 NOW, THEREFORE, in consideration of the
premises and the purchase and acceptance of the Securities by the Holders thereof, the Guarantor covenants and agrees with the Trustee, for the equal and ratable benefit of the Holders, that the Indenture is supplemented and amended, to the extent
expressed herein as follows: 
 1. Generally. 

(a) Capitalized terms used herein and not otherwise defined shall have the respective meanings ascribed thereto in the Indenture. 

(b) The rules of construction set forth in the Indenture shall be applied hereto as if set forth in full herein.

Securities or the obligations of the Company hereunder or thereunder, that: 

  
 F-2 

	 	(i)	 the principal of, premium, if any, and interest on the Securities shall be promptly paid in full when due,
whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium, if any, and interest on the Securities, if lawful (subject in all cases to any applicable grace period provided in the Indenture), and

	 	(ii)	 in case of any extension of time of payment or renewal of any Securities or any of such other obligations, the
same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so
guaranteed for whatever reason, the Guarantor shall be jointly and severally obligated to pay the same immediately. The Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 

(b) The Guarantor hereby agrees that, to the maximum extent permitted under applicable law, its obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Securities or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Securities with respect to any provisions hereof or thereof, the
recovery of any judgment against the Company, any action to enforce the same or any other circumstance that might otherwise constitute a legal or equitable discharge or defense of the Guarantor. 

(c) The Guarantor, pursuant to Section 7.02 of the First Supplemental Indenture, hereby waives diligence, presentment, demand of payment,
filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Guarantee shall not be discharged
except by complete performance of the obligations contained in the Securities and the Indenture. 
 (d) The Guarantor agrees that if any
Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors, or any custodian, trustee, liquidator or other similar official acting in relation to any of the Company or the Guarantors, any amount paid by any
of them to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. 

(e) The Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations
guaranteed hereby until payment in full of all obligations guaranteed hereby. 
 (f) The Guarantor agrees that, as between the Guarantors, on
the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 5 of the Indenture for the purposes of this Guarantee, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 5 of the Indenture, such
obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of this Guarantee. 

(g) If the Guarantor makes a payment under its Guarantee, the Guarantor shall have the right to seek contribution from any non-paying Guarantor, so long as the exercise of such right does not impair the rights of the Holders under the Guarantee. 

(h) The Guarantor confirms, pursuant to Section 7.02 of the First Supplemental Indenture, that the maximum aggregate amount guaranteed
hereunder shall not exceed the maximum amount that can be hereby guaranteed without rendering this Guarantee voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors
generally.

 3. Execution and Delivery. The Guarantor agrees that the Guarantee shall remain in
full force and effect notwithstanding any failure to endorse on each Security a notation of such Guarantee. 
 4. Guarantor May
Consolidate, etc., on Certain Terms. 
 (a) Except as set forth in Section 5 hereto, the Guarantor agrees that it may not sell,
lease, transfer, convey or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not the Guarantor is the surviving Person), another Person, other than the Company or another Guarantor,
unless (1) immediately after giving effect to that transaction, no Default or Event of Default exists and (2) the Person acquiring the property in any such sale, lease, transfer, conveyance or other disposition or the Person formed by or
surviving any such consolidation or merger (if other than the Guarantor) is organized or existing under the laws of the United States of America, any State thereof or the District of Columbia and assumes all the obligations of the Guarantor under
the Indenture and the Guarantee pursuant to a supplemental indenture satisfactory to the Trustee. 
 (b) In case of any such consolidation,
merger, sale, lease, transfer, conveyance or other disposition governed by Section 4(a)(2), above, upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the
Trustee, of the Guarantee endorsed upon the Securities and the due and punctual performance of all of the covenants and conditions to be performed by the Guarantor pursuant to the Indenture, such successor Person shall succeed to and be substituted
for the Guarantor with the same effect as if it had been named herein as the Guarantor. Such successor Person thereupon may cause to be signed any or all of the Guarantees to be endorsed upon all of the Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the Trustee. Any Guarantee so issued shall in all respects have the same legal rank and benefit under the Indenture as the Guarantees theretofore and thereafter issued in
accordance with the terms of the Indenture as though all of such Guarantees had been issued at the date of the execution hereof. 
 5.
Release.

connection with any sale or other disposition of all of the capital stock of the Guarantor, or all or substantially all of the Guarantor’s assets, to a Person that is not (either before or after giving effect to such transaction) the Company or
a Domestic Subsidiary of the Company required to deliver a Guarantee under Section 4.03 of the First Supplemental Indenture; (ii) upon Legal Defeasance or Covenant Defeasance as permitted under the Indenture; or (iii) upon release or
discharge of all guarantees by the Guarantor of all other indebtedness of the Company, except a discharge or release by or as a result of payment under such guarantees of other indebtedness of the Company. In addition, if applicable, the Guarantor
shall be automatically released and relieved of any obligations under its Guarantee in accordance with Section 4.03 of the First Supplemental Indenture. 

(b) Upon delivery by the Company to the Trustee of an Officer’s Certificate to the effect that one of the foregoing requirements has been
satisfied and the conditions to the release of the Guarantor under this Section 5 have been met, the Trustee shall execute any documents reasonably required in order to evidence the release of the Guarantor from its obligations under its
Guarantee. If the Guarantor is not released from its obligations under the Guarantee, the Guarantor shall remain liable for the full amount of principal of, premium, if any, and interest on the Securities and for any other obligations of the Company
as provided in Article 7 of the First Supplemental Indenture. 
 6. No Recourse Against Others. Pursuant to Section 1.15 of the
Indenture, no director, officer, employee, incorporator, stockholder, member, manager or partner of the Guarantor shall have any liability for any obligations of the Guarantor under the Securities, the Indenture, the Guarantee or for any claim based
on, in respect of, or by reason of, such obligations or their creation.

Execution Version 

EXECUTIVE EMPLOYMENT AGREEMENT 

This Executive Employment Agreement (this “Agreement”) is entered into between Allovir, Inc., a Delaware corporation
(“Company”) and Diana Brainard (“Employee”). This Agreement is effective as of the date the Agreement becomes fully executed by the parties (the “Effective Date”). 

Now, for good and valuable consideration, the receipt of which is hereby confirmed, the Company and Employee agree as follows: 

1. Position and Duties. The Company will employ Employee as the Chief Executive Officer of the Company. Employee will report to
the Company’s Board of Directors (the “Board”) and will render such business and professional services in the performance of her duties, consistent with Employee’s position, as shall reasonably be assigned to her by
the Board. Employee’s employment shall begin on a date mutually agreeable to Employee and the Company and shall continue in such capacity until it terminates in accordance with Section 10 below. 

2. Service to the Company. Except as otherwise specified herein, Employee will be expected to devote her full working time and
attention to the business of the Company, and will not render services to any other business without the prior approval of the Board or, directly or indirectly, engage or participate in any business that is competitive in any manner with the
business of the Company; provided, however, that Employee may continue to serve on the boards of directors and advisory boards on which Employee presently serves, all of which have been disclosed to the Company, and may serve on additional
boards (whether advisory or boards of directors) with the prior approval of the Board, not to be unreasonably withheld and may service on the board of civic or charitable organizations and manage her personal investments, in each case, except as
would materially interfere with her duties to the Company. Employee will also be expected to comply with and be bound by the Company’s operating policies, procedures and practices that are from time to time in effect during the term of her
employment and are provided to Employee. 
 3. Board Service. Employee will continue to serve as member of the AlloVir, Inc.
Board of Directors and for so long as Employee continues to serve as the Chief Executive Officer of the Company, Employee will be nominated by the Company to serve on the Board. Employee may be removed from the Board in accordance with applicable
law and the Company’s bylaws. If Employee ceases to be employed by the Company, Employee will resign from all Board positions at the request of the Board. 

4. At-Will Employment. Employee and the Company understand and acknowledge that
Employee’s employment with the Company constitutes “at-will” employment, and the employment relationship may be terminated at any time, with or without cause and with or without notice.

 Execution Version 

 

 5. Compensation and Benefits. 

5.1 Base Salary. The Company shall pay the Employee an annual base salary of $584,000 (as adjusted from time to
time in accordance with the terms hereof, the “Base Salary”), payable in accordance with the Company’s normal payroll practices. The Board shall periodically review (at least annually) Employee’s Base Salary,
provided that any changes thereto shall be determined by the Board in its sole and absolute discretion. 
 5.2
Annual Bonus. Employee will be eligible to receive an annual cash bonus with a target bonus opportunity of 60% of Employee’s then current Base Salary (the “Target Annual Bonus”), upon the achievement of annual
performance goals determined by the Board (and Employee shall be eligible to receive an annual bonus above such target level for performance in excess of target levels). Annual corporate performance goals shall be determined no later than the end of
January of the performance year, which generally shall be coincident with the calendar year. The Board, at its sole discretion, may increase Employee’s Annual Bonus or award an additional bonus to the Employee for extraordinary service to the
Company or other factors it determines to be appropriate in its sole discretion. The annual bonus shall be paid during the fiscal year that follows the year to which it relates, not later than the date Company-wide annual bonuses are paid. To
receive payment of any bonus Employee must be employed by the Company at the time bonuses are paid, except as provided below. 

5.3 Employee Benefits. Employee shall be entitled to participate in all employee benefit plans and arrangements,
including, but not limited to, medical, dental, vision and long-term disability insurance benefits and arrangements, as are made available by the Company to its other senior executives, subject to the terms and conditions thereof. 

5.4 Vacation. Employee will be entitled to paid vacation (in addition to Company holidays) pursuant to the terms
of the Company’s vacation policy as may exist from time to time, but in all events not less than four (4) weeks. 

5.5 Relocation Benefits. The Company agrees to reimburse Employee within sixty (60) days of Employee’s
submission of documentation of the same (or, if reasonably practicable and requested by Employee, the Company shall directly pay) for the following relocation related expenses incurred in connection with Employee’s move to the Company’s
headquarters in the greater Boston area: (i) costs related to packing and moving Employee’s household goods and belongings (including automobiles); (ii) real estate commissions and other costs associated with selling Employee’s home
in the greater San Francisco Bay area, in an amount under this clause (ii) up to $250,000; (iii) reasonable travel expenses for Employee and Employee’s family associated with moving; and (iv) reimbursement for up to 12 months of rent
(which may include periods prior to Employee’s start date) for housing for Employee and Employee’s family in an aggregate amount for such rent of not more than $180,000. The Corporation shall pay to Employee such additional compensation as
is necessary (after taking into account all federal, state, and local income taxes payable by Employee as a result of the receipt of such additional compensation) to place Employee in the same after-tax
position Employee would have been in had no such tax (or any interest or penalties thereon) been paid or incurred with 

  
 2 

 Execution Version 

 

 
respect to any of such amounts (the “Tax Gross-Up”). The Corporation shall pay the applicable portion of the Tax-Gross Up at the time the related expense is paid or reimbursed, as applicable. Employee agrees to reimburse Company for the after-tax amount of such payments if Employee
voluntarily terminates Employee’s employment with the Company without Good Reason (and other than due to Disability) prior to the completion of twelve (12) months of service to the Company. 

6. Equity Matters. 

6.1 Not later than thirty (30) days after the Employee’s commencement of employment with the Company, the
Company will grant Employee the following equity awards under the 2020 AlloVir Stock Option and Incentive Plan (the “Plan”): (i) a stock option to purchase 500,000 shares of the Company’s common stock (the
“Time-Based Option”), (ii) 30,000 restricted stock units (the “Sign-On RSU Award”) and (iii) 170,000 restricted stock units (“the “Time-Based RSU
Award”). The exercise price of each share subject to the Option will be equal to the closing trading price of the Company’s common stock on the date of grant. 

6.2 All equity grants required by Paragraph 6.1 will be evidenced in writing by, and subject to the terms of the Plan
and a Grant Agreement attached hereto as Exhibit A (in the case of the Time-Based Option), Exhibit B (in the case of the Sign-On RSU Award and the Time-Based RSU Award, with appropriate changes
for the respective award) and will vest in accordance with the terms of such agreements. 
 6.3 For the avoidance of
doubt, all equity granted to Employee in respect of her service of a member of the Board prior the commencement of her employment with the Company will continue to vest in accordance with its regular vesting schedule for as long as Employee provides
services to the Company either as a member of the Board or an employee of the Company. 
 7. Expenses. The Company will, in
accordance with applicable Company policies and guidelines, reimburse Employee for all reasonable and necessary expenses incurred by Employee in connection with her performance of services on behalf of the Company. In addition, not later than thirty
(30) days after Employee’s presentation of reasonable documentation thereof, Employee will be reimbursed for all reasonable attorneys’ fees and expenses incurred in connection with this Agreement and her employment with the Company,
up to an aggregate cap of $20,000. 
 8. Inventions and Proprietary Information,
Non-Competition. In exchange for, among other things, an offer of employment which Employee acknowledges and agrees is fair and reasonable consideration that is independent from the continuation of
employment with the Company, Employee agrees to the terms of the Restrictive Covenants Agreement attached to this Agreement as Exhibit C (the “Restrictive Covenants Agreement”), which is hereby incorporated by
reference into this Agreement. Employee acknowledges and understands that Employee has been advised by the Company that Employee has the right to consult with counsel prior to signing the Restrictive Covenants Agreement. Employee further
acknowledges and agrees that Employee received the Restrictive Covenants Agreement at least ten (10) business days before the Restrictive Covenants Agreement is to become effective.

 9. Definitions. 

9.1 Cause. For purposes of this Agreement, “Cause” means the occurrence of any of the
following after the Effective Date (i) Employee’s persistent failure to carry out any material lawful duties of Employee or any lawful directions of the Board reasonably consistent with Employee’s duties; provided, however, that
Employee has been given reasonable notice of the specific failure and an opportunity to correct such failure within thirty (30) business days from the date of the notice; (ii) Employee’s conviction of or plea of nolo contendere to a
felony, which has had or will have a detrimental effect on the Company’s reputation or business, (iii) Employee engaging in an act of gross negligence or willful misconduct in the performance of her employment obligations and duties,

the Company’s reputation or business; or (vi) Employee’s material breach of the Restrictive Covenants Agreement. No act or failure to act will be considered “willful” unless Employee has acted, or failed to act, with a lack
of good faith and with a lack of reasonable belief that Employee’s action or failure to act was in the best interest of the Company or any of its affiliates.

Company, such that there is an increase of at least thirty (30) miles of driving distance to such location from Employee’s principal place of residence as of such change; 

(v) Any change in Employee’s reporting relationship so that she no longer reports exclusively to the Board; or 

(vi) A material breach of this Agreement or any equity agreement to which Employee is a party by the Company. 

10. Effect of Separation from Service. For purposes of this Agreement, no payment will be made to Employee upon termination of
Employee’s employment unless such termination constitutes a “separation from service” within the meaning of Section 409A of the Code, and Section 1.409A-1(h) of the
regulations promulgated thereunder. 
 10.1 Separation for Cause, Death, Disability or Voluntary Separation from
Service. In the event of Employee’s separation from service from the Company for Cause or in the event of Employee’s death, Disability or voluntary separation from service at any time (other than for Good Reason or due to Disability)
and for any reason, Employee or her estate will be paid only (i) any earned but unpaid Base Salary, (ii) other unpaid vested amounts or benefits under the compensation, incentive and benefit plans of the Company in which Employee
participates (including accrued vacation earned through her separation from service), and (iii) reimbursement for all reasonable and necessary expenses incurred by Employee in connection with her performance of services on behalf of the Company
in accordance with applicable Company policies and guidelines, in each case as of the effective date of such separation from service (the “Accrued Compensation”). In the event of Employee’s death or Disability,
(i) any unvested stock option or other equity award held by Employee shall be accelerated in vesting in an amount equal to (i) twenty five percent (25%) plus (ii) five percent (5%) for each year of service to the Company of the total
number of shares covered by the option or other award, (ii) the Company will pay Employee any then unpaid annual bonus payable under Paragraph 5.2 above for a performance year that has been completed in accordance with the terms set forth
therein and (iii) the Company will pay Employee a pro-rata annual bonus for the year in which such death or Disability occurs (as determined and paid in accordance with Paragraph 5.2 above) based on the
number of days elapsed prior to such death or Disability. Employee or her estate (or applicable representative or permitted transferee) will be allowed to exercise her vested stock options to purchase the Company’s common stock (and other
awards requiring exercise), if any, during the time period set forth in, and in accordance with, the applicable plan and governing agreements. 

10.2 Separation from Service without Cause or for Good Reason. In the event of Employee’s separation from
service from the Company without Cause or for Good Reason, and provided that Employee delivers to the Company a signed separation agreement and release in a form and manner satisfactory to the Company, which shall include, without limitation, a
general release of claims against the Company and all related persons and 

  
 5 

 Execution Version 

 

 
entities, a reaffirmation of all of the Employee’s Continuing Obligations (as defined below), and, in the Company’s sole discretion, a one-year
post-employment noncompetition restriction in a form substantially similar to the Noncompetition Restriction (as defined in the Restrictive Covenants Agreement attached hereto as Exhibit D (the “Separation Agreement and
Release”) , and (ii) the Separation Agreement and Release becoming irrevocable all within sixty (60) days following Employee’s separation from service (or such shorter period as set forth in the Separation and Release
Agreement), which shall include a seven (7) business day revocation period, then, in addition to the Accrued Compensation, Employee shall be entitled to the following: 

(i) A lump sum payment equal to thirty-six (36) months (the “Severance
Period”) of the Employee’s then current Base Salary payable on the sixty-first (61st) day following the date of Employee’s separation from service (or, if earlier, on the first payroll date after the Separation and Release
Agreement has become irrevocable); 
 (ii) A lump sum payment for Target Annual Bonus payable on the sixty-first (61st) day
following the date of Employee’s separation from service (collectively, with the payment provided for in Paragraph 10.2(i), the “Severance Amount”); 

(iii) Notwithstanding in the foregoing, in the event Employee is entitled to any payments pursuant to the Restrictive Covenants
Agreement, the Severance Amount will be reduced on a dollar-for-dollar basis by the amount Employee is paid pursuant to the Restrictive Covenants Agreement;
provided that any such reduction shall not be effected in any manner that results in any additional taxes under Section 409A; 

(iv) Provided Employee timely elects to continue health coverage under the Consolidated Omnibus Budget Reconciliation Act of
1985, as amended (“COBRA”), reimbursement for any monthly COBRA premium payments made by Employee for Employee and her eligible dependents until the earliest of (a) the expiration of the Severance Period;
(b) Employee’s eligibility for group medical plan benefits under any other employer’s group medical plan; or (c) the cessation of Employee’s continuation rights under COBRA; provided, however, if the Company determines that
it cannot pay such amounts to the group health plan provider or the COBRA provider (if applicable) without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then the Company
shall convert such payments to payroll payments directly to Employee for the time period specified above. Such payments shall be subject to tax-related deductions and withholdings and paid on the
Company’s regular payroll dates. For the avoidance of doubt, the taxable payments described above may be used for any purpose, including, but not limited to, continuation coverage under COBRA; and, 

(v) Notwithstanding the provisions of Paragraph 6 or their otherwise applicable terms, all unvested equity awards held by
Employee at the time of such separation from service shall accelerate in full and, as applicable, become fully exercisable and all stock options (and other awards requiring exercise) will remain vested and exercisable thereafter in accordance with
the terms of the applicable award agreement.

 11.1 Parachute Payments. In the event that any payments or
benefits provided for in this Agreement or otherwise payable to Employee (collectively, the “Payments”) (i) constitute “parachute payments” within the meaning of Section 280G of the Code and
(ii) but for this Section, would be subject to the excise tax imposed by Section 4999 of the Code, then the Payments shall be payable either (i) in full, or (ii) as to such lesser amount which would result in no portion of the
Payments being subject to the excise tax under Section 4999 of the Code, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999 of the Code,
results in the receipt by Employee on an after-tax basis, of the greatest amount of Payments, notwithstanding that all or some portion of such severance benefits may be taxable under Section 4999 of the
Code. Any reduction to the Payments required under this Section shall be made by the Company in its reasonable discretion in the following order and in a manner intended to comply with Section 409A of the Code (as determined by the Company):
(i) payments that are payable in cash that are valued at full value under Treasury Regulation Section 1.280G-1, Q&A 24(a) will be reduced (if necessary, to zero), with amounts that are payable last
reduced first; (ii) payments and benefits due in respect of any equity valued at full value under Treasury Regulation Section 1.280G-1, Q&A 24(a), with the highest values reduced first (as such
values are determined under Treasury Regulation Section 1.280G-1, Q&A 24), will next be reduced; (iii) payments that are payable in cash that are valued at less than full value under Treasury
Regulation Section 1.280G-1, Q&A 24, with amounts that are payable last reduced first, will next be reduced; (iv) payments and benefits due in respect of any equity valued at less than full value
under Treasury Regulation Section 1.280G-1, Q&A 24, with the highest values reduced first (as such values are determined under Treasury Regulation
Section 1.280G-1, Q&A 24), will next be reduced; and (v) all other non-cash benefits not otherwise described in clauses (ii) or (iv) hereof will be
next reduced pro-rata. Any reductions made pursuant to each of clauses (i)-(v) of the immediately preceding sentence will be made in the following manner: first, a
pro-rata reduction of cash payment and payments and benefits due in respect of any equity not subject to Section 409A of the Code, and second, a pro-rata reduction
of cash payments and payments and benefits due in respect of any equity subject to Section 409A of the Code as deferred compensation. Unless the Company and Employee otherwise agree in writing, any determinations required under this Paragraph
shall be made in writing by the Company’s independent public accountants (the “Accountants”), whose determinations (after consulting with Employee and her advisors and taking into account any comments in good faith)
shall be conclusive and binding upon Employee and the Company for all purposes. The Company shall cause the Accountants to provide its determinations and any supporting calculations with respect to Employee to the Company and Employee. For purposes
of making the calculations required by this Paragraph, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G

  
 7 

 Execution Version 

 

 
and 4999 of the Code. The Company and Employee shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under
this Paragraph. The Company shall bear all costs in connection with such determinations, including all fees of the Accountants and all costs the Accountants may incur in connection with any calculations contemplated by this Paragraph. 

12. Miscellaneous. 

12.1 Arbitration. Employee and the Company agree to submit to mandatory binding arbitration, in Boston,
Massachusetts any and all claims arising out of or related to this Agreement and Employee’s employment with the Company and the termination thereof, except that each party may, at its or Employee’s option, seek injunctive relief in court
related to the improper use, disclosure or misappropriation of a party’s proprietary, confidential or trade secret information. EMPLOYEE AND THE COMPANY HEREBY WAIVE ANY RIGHTS TO TRIAL BY JURY IN REGARD TO SUCH CLAIMS. This Agreement to
arbitrate does not restrict Employee’s right to file administrative claims Employee may bring before any government agency where, as a matter of law, the parties may not restrict Employee’s ability to file such claims (including, but not
limited to, the National Labor Relations Board, the Equal Employment Opportunity Commission and the Department of Labor). However, Employee and the Company agree that, to the fullest extent permitted by law, arbitration shall be the exclusive remedy
for the subject matter of such administrative claims. The arbitration shall be conducted through JAMS before a single neutral arbitrator, in accordance with the JAMS employment arbitration rules then in effect. The arbitrator shall issue a written
decision that contains the essential findings and conclusions on which the decision is based. 
 12.2
Indemnification. The Company shall indemnify Employee with respect to activities in connection with her employment hereunder to the fullest extent provided in the Company’s bylaws. Employee will at all times during her employment and
during the period thereafter that she may be subject to claims in respect of her employment be named as an insured on the director and officer liability insurance policy currently maintained, or as may be maintained by the Company from time to time
on a basis that is no less favorable than the Company’s other officers and directors, and, in addition, Employee will enter into an indemnification agreement provided to other similarly situated executive officers and directors of the Company,
the form of which is attached as Exhibit E. 
 12.3 Section 409A. To the extent (i) any payments or
benefits to which Employee becomes entitled under this Agreement, or under any agreement or plan referenced herein, in connection with Employee’s termination of employment with the Company constitute deferred compensation subject to
Section 409A of the Code and (ii) Employee is deemed at the time of such termination of employment to be a 

  
 8 

 Execution Version 

 

 
“specified employee” under Section 409A of the Code, then such payments shall not be made or commence until the earliest of (a) the expiration of the six
(6) month period measured from the date of Employee’s “separation from service” (as such term is at the time defined in Treasury Regulations under Section 409A of the Code) from the Company; or (b) the
date of Employee’s death following such separation from service; provided, however, that such deferral shall only be effected to the extent required to avoid adverse tax treatment to Employee, including (without limitation) the
additional twenty percent (20%) tax for which Employee would otherwise be liable under Section 409A(a)(1)(B) of the Code in the absence of such deferral. Upon the expiration of the applicable deferral period, any payments which would have
otherwise been made during that period (whether in a single sum or in installments) in the absence of this paragraph shall be paid to Employee or Employee’s beneficiary in one lump sum (without interest). Any termination of Employee’s
employment is intended to constitute a “separation from service” and will be determined consistent with the rules relating to a “separation from service” as such term is defined in Treasury Regulation Section 1.409A-1. It is intended that each installment of the payments provided hereunder constitute separate “payments” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i). It is further intended that payments hereunder satisfy, to the greatest extent possible, the exemption from the application of Section 409A of the Code (and any state law of
similar effect) provided under Treasury Regulation Section 1.409A-1(b)(4) (as a “short-term deferral”). To the extent that any provision of this Agreement is ambiguous as to its
compliance with Section 409A of the Code, the provision will be read in such a manner so that all payments hereunder comply with Section 409A of the Code. Except as otherwise expressly provided herein, to the extent any expense
reimbursement or the provision of any in-kind benefit under this Agreement is determined to be subject to Section 409A of the Code, the amount of any such expenses eligible for reimbursement, or the
provision of any in-kind benefit, in one calendar year shall not affect the expenses eligible for reimbursement in any other taxable year (except for any lifetime or other aggregate limitation applicable to
medical expenses), in no event shall any expenses be reimbursed after the last day of the calendar year following the calendar year in which Employee incurred such expenses, and in no event shall any right to reimbursement or the provision of any in-kind benefit be subject to liquidation or exchange for another benefit. 
 12.4
Severability. If any provision of this Agreement shall be found by any arbitrator or court of competent jurisdiction to be invalid or unenforceable, then the parties hereby waive such provision to the extent of its invalidity or
unenforceability and agree that all other provisions in this Agreement shall continue in full force and effect. 

12.5 No Waiver. The failure by either party at any time to require performance or compliance by the other of any
of its obligations or agreements shall in no way affect the right to require such performance or compliance at any time 

  
 9 

 Execution Version 

 

 
thereafter. The waiver by either party of a breach of any provision hereof shall not be taken or held to be a waiver of any preceding or succeeding breach of such provision or as a waiver of the
provision itself. No waiver of any kind shall be effective or binding, unless it is in writing and is signed by the party against whom such waiver is sought to be enforced. 

12.6 Assignment. This Agreement and all rights hereunder are personal to Employee and may not be transferred or
assigned by Employee at any time. The Company may assign its rights, together with its obligations hereunder, to any purchaser of all or substantially all of its business and assets, provided, however, that any such assignee assumes the
Company’s obligations hereunder and such assignment shall not increase the scope any restrictive covenant applicable to Employee prior to such assignment. 

12.7 Withholding. All sums payable to Employee hereunder shall be in United States Dollars and shall be reduced
by all federal, state, local and other withholding and similar taxes and payments required by applicable law. 
 12.8
Continuing Obligations. For purposes of this Agreement, the obligations that arise in the Restrictive Covenants Agreement, the Plan, and equity agreements by which Employee is bound, and any other agreement relating to confidentiality,
assignment of inventions, or other restrictive covenants shall collectively be referred to as the “Continuing Obligations.” 

12.9 Amendment. The parties understand and agree that this Agreement may not be amended, modified or waived, in
whole or in part, except in a writing executed by Employee and the Company. 
 12.10 Notices. All notices, if
any, and all other communications, if any, required or permitted under this Agreement shall be in writing and hand delivered, sent by registered first class mail, postage pre-paid, or sent by nationally
recognized express courier service. Such notices and other communications shall be effective upon receipt if hand delivered or sent via facsimile, five (5) days after mailing if sent by mail, and one (l) day after dispatch if sent by
express courier, to the following addresses, or such other addresses as any party shall notify the other parties:

 Execution Version 

 

 EMPLOYEE RESTRICTIVE COVENANTS AGREEMENT 

In exchange for, among other things, an offer of employment, which Employee (as defined below) acknowledges and agrees is fair and reasonable consideration
that is independent from the continuation of employment with the Company, Diana Brainard (“Employee”) together with Allovir, Inc., its subsidiaries, affiliates, successors or assigns (together the “Company”), enter
into this Restrictive Covenants Agreement (this “Agreement”), and hereby agree to the following: 
 1.
Proprietary Information. 
 (a) Company Information. Employee agrees at all times during the
term of Employee’s employment and thereafter, to hold in strictest confidence, and not to use, except for the benefit of the Company, or to disclose to any person, firm or corporation without written authorization of the Board of Directors of
the Company, any Proprietary Information of the Company, except under a non-disclosure agreement duly authorized and executed by the Company, otherwise in Employee’s good faith performance of her duties
or to her tax, legal and other advisors on a confidential basis. Employee understands that “Proprietary Information” means any non-public information regarding or relating to the Company or its
products including: (1) the actual or reasonably anticipated business or research and development of the Company, technical data, trade secrets or know-how, including, but not limited to, research,
product plans or other information regarding the Company’s products or services and markets therefore; (2) research, clinical or other trials, developments, inventions, processes, formulas, technology, designs, drawings, engineering,
software, hardware configuration information, marketing, finances or other business information; (3) customer lists and customers (including, but not limited to, customers of the Company on whom Employee called or with whom Employee became
acquainted during the term of Employee’s employment); (4) the identity, skills and compensation of employees, consultants, or contractors; (5) policies and procedures of the Company; (6) anything related to Company Inventions (as
defined herein); and (7) Third Party Information (as defined herein). Employee further understands that Proprietary Information does not include any of the foregoing items which have become publicly known and made generally available through no
wrongful act of the Employee or of others who were under confidentiality obligations as to the item or items involved or improvements or new versions thereof. Notwithstanding the foregoing, pursuant to 18 U.S.C. Section 1833(b),
Employee shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that: (1) is made in confidence to a Federal, State, or local government official, either directly or
indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected violation of law; or (2) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. In
addition, notwithstanding the foregoing, Employee shall not be prohibited from disclosing Proprietary Information to a government agency as a whistleblower. 

(b) Third Party Information. Employee recognizes that the Company has received and in the future will
receive from third parties their confidential or proprietary 

  
 1 

 Execution Version 

 

 
information subject to a duty on the Company’s part to maintain the confidentiality of such information and to use it only for certain limited purposes (“Third Party
Information”). Employee agrees to hold all Third Party Information in the strictest confidence and not to disclose it to any person, firm or corporation or to use it except as necessary in carrying out Employee’s work for the Company
consistent with the Company’s agreement with such third party. 
 2. Inventions. 

(a) Inventions Retained and Licensed. Employee has attached hereto, as Exhibit 1, a list describing
all inventions, original works of authorship, developments, improvements, and trade secrets which were made by Employee prior to Employee’s employment with the Company (collectively referred to as “Prior Inventions”), which
belong to Employee, which relate to the Company’s proposed business, products or research and development, and which are not assigned to the Company hereunder; or, if no such list is attached, Employee represents that there are no such Prior
Inventions. If in the course of Employee’s employment with the Company, Employee incorporates into a Company product, process or service a Prior Invention owned by Employee or in which Employee has an interest, Employee hereby grants to the
Company a nonexclusive, royalty-free, fully paid-up, irrevocable, perpetual, worldwide license to make, have made, modify, use and sell such Prior Invention as part of or in connection with such product,
process or service, and to practice any method related thereto. 
 (b) Assignment of Inventions.
Employee agrees that Employee will promptly make full written disclosure to the Company, will hold in trust for the sole right and benefit of the Company, and hereby assign (or, for future inventions, agree to assign) to the Company, or its
designee, all Employee’s right, title, and interest in and to any and all inventions, original works of authorship, writings, developments, concepts, improvements, designs, discoveries, ideas, processes, formulas, data, trademarks or trade
secrets, whether or not patentable or registrable under copyright or similar laws, which Employee may solely or jointly conceive or develop or reduce to practice within the scope of Employee’s employment, or cause to be conceived or developed
or reduced to practice, during the period of time Employee is employed by the Company (collectively referred to as “Inventions”), except as provided in Paragraph 2(f) below. Employee agrees that Company will
exclusively own all work product that is made by Employee (solely or jointly with others) within the scope of Employee’s employment. Employee further acknowledges that all original works of authorship which are made by Employee
(solely or jointly with others) within the scope of and during the period of Employee’s employment with the Company and which are protectable by copyright are “works made for hire,” as that term is defined in the United States
Copyright Act. Employee understands and agrees that the decision whether or not to commercialize or market any Invention developed by Employee solely or jointly with others is within the Company’s sole discretion and for the Company’s sole
benefit and that no royalty will be due to Employee as a result of the Company’s efforts to commercialize or market any such Invention. Employee acknowledges and agrees that nothing in this Agreement shall be deemed to grant, by implication,
estoppel or otherwise, a license from the Company to me to make, use, license, or transfer in any way an existing or future Invention.  

  
 2 

 Execution Version 

 

 (c) Inventions Assigned to the United States. Employee
agrees to assign to the United States government all Employee’s right, title, and interest in and to any and all Inventions whenever such full title is required to be in the United States by a contract between the Company and the United States
or any of its agencies. 
 (d) Maintenance of Records. Employee agrees to keep and maintain adequate and
current written records of all Inventions made by Employee (solely or jointly with others) during the term of Employee’s employment with the Company. The records will be in the form of notes, sketches, drawings, and any other format that may be
specified by the Company. The records will be available to and remain the sole property of the Company at all times. 
 (e)
Patent and Copyright Registrations. Employee agrees to assist the Company, or its designee, at the Company’s expense, in every proper way to secure the Company’s rights in the Inventions and any copyrights, patents,
mask work rights or other intellectual property rights relating thereto in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications,
oaths, assignments and all other instruments which the Company shall deem necessary in order to apply for and obtain such rights and in order to assign and convey to the Company, its successors, assigns, and nominees the sole and exclusive rights,
title and interest in and to such Inventions, and any copyrights, patents, mask work rights or other intellectual property rights relating thereto. Employee further agrees that Employee’s obligation to execute or cause to be executed, when it
is in Employee’s power to do so, any such instrument or papers shall continue after the termination of this Agreement. If the Company is unable because of Employee’s mental or physical incapacity or for any other reason to secure
Employee’s signature to apply for or to pursue any application for any United States or foreign patents or copyright registrations covering Inventions or original works of authorship assigned to the Company as above, then Employee hereby
irrevocably designates and appoints the Company and its duly authorized officers and agents as Employee’s agent and attorney in fact, to act for and in Employee’s behalf and stead to execute and file any such applications and to do all
other lawfully permitted acts to further the prosecution and issuance of letters patent or copyright registrations thereon with the same legal force and effect as if executed by Employee. 

(f) Exceptions. This Agreement does not obligate Employee to assign to the Company any Invention that, in the
sole judgment of the Company, reasonably exercised, is developed entirely on my own time and does not relate to the business efforts or research and development efforts in which, during the period of my employment, the Company actually is engaged or
reasonably would be engaged, and does not result from the use of premises or equipment owned or leased by the Company. However, Employee will also promptly disclose to the Company any such Inventions for the purpose of determining whether they
qualify for such exclusion. Employee understands that to the extent this 

  
 3 

 Execution Version 

 

 
Agreement is required to be construed in accordance with the laws of any state which precludes a requirement in an employee agreement to assign certain classes of inventions made by an employee,
this Paragraph 2 will be interpreted not to apply to any invention that a court rules and/or the Company agrees falls within such classes. 

3. Former Employer Information. Employee agrees that Employee will not, during Employee’s employment
with the Company, improperly use or disclose any proprietary information or trade secrets of any former employer or other person or entity and that Employee will not bring onto the premises of the Company any unpublished document or proprietary
information belonging to any such employer, person or entity unless consented to in writing by such employer, person or entity. Employee further agrees that Employee will not incorporate into any Invention any Proprietary Information or trade
secrets of any former employer or other person or entity. 
 4. Conflicting Employment. Subject to the
forgoing, Employee agrees that, during the term of Employee’s employment with the Company, Employee will not engage in any other employment, occupation or consulting directly related to the Company’s business, nor will Employee engage in
any other activities that conflict with Employee’s obligations to the Company (with it being understood that activities which are expressly permitted under Employee’s employment agreement with the Employee’s employment agreement will
not be deemed in conflict with such obligations). 
 5. Non-Competition. 

(a) In order to protect the Company’s Proprietary Information and goodwill, during Employee’s employment and for a
period of (i) one (1) year following the date of the cessation of Employee’s employment with the Company (the “Last Date of Employment”) or such shorter period as the Company designates in writing to Employee (which
designation must be made no later than the date any waiver must be made under Paragraph 5(b)(iii)), or (ii) two (2) years following the Last Date of Employment if Employee breaches her fiduciary duty to the Company or if Employee has unlawfully
taken, physically or electronically, property belonging to the Company (in either case, the “Restricted Period”), Employee shall not directly or indirectly, whether as owner, partner, shareholder, director, manager, consultant,
agent, employee, co-venturer or otherwise, anywhere in the world, engage or otherwise participate in any business that develops, manufactures or markets any products, performs any services, or conducts any
research focused on using T-cell therapy to address viruses or virus-related diseases (the “Noncompetition Restriction”). 

(b) Notwithstanding the foregoing, the Noncompetition Restrictions shall not apply: (i) if the Company terminates
Employee’s employment without “cause” (within the meaning of Mass. Gen. Laws Chapter 149, Sec 24L (c)); (ii) if the Employee has been laid off by the Company; or (iii) if the Company waives the Noncompetition Restriction. 

  
 4 

 Execution Version 

 

 (c) In the event that the Noncompetition Restriction applies to Employee, the Company shall
make garden leave payments to Employee for the post-employment portion of the Restricted Period (but for not more than 12 months following the end of Employee’s employment) at the rate of 50% of the highest annualized base salary paid to
Employee by the Company within the two-year period preceding the last day of Employee’s employment (the “Garden Leave Pay”). Employee acknowledges and agrees that the Garden Leave Pay is
consideration mutually agreed upon by the Company and Employee, and in exchange for Employee’s agreement to the Noncompetition Restriction. Employee further acknowledges and agrees that any Garden Leave Pay Employee receives pursuant to this
Agreement shall reduce (and shall not be in addition to) any severance or separation pay that Employee is otherwise entitled to receive from the Company pursuant to any agreement, plan or otherwise; provided that any such reduction shall not
be effected in any manner that results in any additional taxes under Section 409A. 
 (d) Employee acknowledges that this covenant in
this Paragraph 5 is necessary because the Company’s legitimate business interests cannot be adequately protected solely by the other covenants in this Agreement. 

6. Returning Company Documents. Employee agrees that, at (or as soon as reasonably practicably after) the

be enforceable to the extent compatible with the applicable law as it shall then appear.
