 AMENDED AND RESTATED TRUST AGREEMENT, dated as of January 1, 2021 (as amended,
supplemented or otherwise modified and in effect from time to time, this “Agreement”), between CARMAX AUTO FUNDING LLC, a Delaware limited liability company, as depositor (the “Depositor”), and U.S. BANK TRUST
NATIONAL ASSOCIATION, a national banking association, as owner trustee and not in its individual capacity (in such capacity, the “Owner Trustee”). 

WHEREAS, CarMax Auto Owner Trust 2021-1 was created on October 27, 2020 pursuant to (i) a
Trust Agreement, dated as of October 27, 2020 (the “Initial Trust Agreement”), between the Depositor and the Owner Trustee and (ii) the filing of a certificate of trust with the Secretary of State of the State of Delaware
on October 27, 2020; and 
 WHEREAS, the Depositor and the Owner Trustee wish to amend and restate the Initial Trust Agreement on the
terms and conditions hereinafter set forth; 
 NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained and
other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Depositor and the Owner Trustee hereby agree as follows: 

ARTICLE I 
 DEFINITIONS 

Section 1.1 Definitions. Capitalized terms used herein that are not otherwise defined shall have the meanings ascribed thereto in
Appendix A to the Sale and Servicing Agreement, dated as of the date hereof, among CarMax Auto Owner Trust 2021-1, as issuer, the Depositor, and CarMax Business Services, LLC, as servicer, as amended,
supplemented or otherwise modified and in effect from time to time.

delivered pursuant hereto or thereto, accounting terms not defined in this Trust Agreement or in any such certificate or other document, and accounting terms partly defined in this Trust Agreement or in any such certificate or other document to the
extent not defined, shall have the respective meanings assigned to them under generally accepted accounting principles. To the extent that the definitions of accounting terms in this Trust Agreement or in any such certificate or other document are
inconsistent with the meanings of such terms under generally accepted accounting principles, the definitions contained in this Trust Agreement or in any such certificate or other document shall control. 

(c) The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Trust Agreement

 ARTICLE
II 
 ORGANIZATION OF THE TRUST 

Section 2.1 Name. The Trust shall be known as “CarMax Auto Owner Trust 2021-1,”
in which name the Owner Trustee may conduct the business of the Trust, make and execute contracts and other instruments on behalf of the Trust and sue and be sued on behalf of the Trust. 

Section 2.2 Office. The office of the Trust shall be in care of the Owner Trustee at the Corporate Trust Office or at such other
address as the Owner Trustee may designate by written notice to the Certificateholders and the Depositor. 
 Section 2.3 Purposes
and Powers. The purpose of the Trust is, and the Trust shall have the power and authority, to engage solely in the following activities: 

(i) to issue the Notes pursuant to the Indenture and the Certificates pursuant to this Trust Agreement, and to sell the Notes
upon the written order of the Depositor; 
 (ii) to establish or cause to be established the Reserve Account which the
Depositor will initially fund on the Closing Date, to pay the organizational, start-up and transactional expenses of the Trust and to pay the balance to the Depositor pursuant to the Sale and Servicing
Agreement; 
 (iii) to pay interest on and principal of the Notes and to pay Excess Collections to the Certificateholders;

 (iv) to assign, grant, transfer, pledge, mortgage and convey the Owner Trust Estate (other than the Certificate Payment
Account and the proceeds thereof) to the Indenture Trustee pursuant to the Indenture; 
 (v) to enter into and perform its
obligations under the Transaction Documents to which it is to be a party; 

  
 2 

 (vi) subject to compliance with the Transaction Documents, to engage in such
other activities as may be required in connection with conservation of the Owner Trust Estate and the making of distributions to the Noteholders and the Certificateholders; 

(vii) to acquire, hold and manage the assets of the Trust, including the Receivables, and the proceeds of those assets; and

 (viii) to engage in those activities, including entering into agreements, that are necessary, suitable or convenient to
accomplish the foregoing or are incidental thereto or connected therewith. 
 The Trust is hereby authorized to engage in the foregoing
activities. The Trust shall not engage in any activity other than in connection with the foregoing or other than as required or authorized by the terms of this Trust Agreement or the other Transaction Documents. 

Section 2.4 Appointment of Owner Trustee. The Depositor hereby appoints the Owner Trustee as trustee of the Trust effective as of
the date hereof, to have all the rights, powers and duties set forth herein and in the Statutory Trust Statute. 
 Section 2.5
Initial Capital Contribution of Owner Trust Estate. On the Closing Date, the Depositor will sell the Receivables and other related property to the Trust in exchange for the Notes and Certificates pursuant to Section 2.1(a) of the Sale
and Servicing Agreement. The Depositor shall pay organizational expenses of the Trust as they may arise or shall, upon the request of the Owner Trustee, promptly reimburse the Owner Trustee for any such expenses paid by the Owner Trustee. 

Section 2.6 Declaration of Trust. The Owner Trustee hereby declares that it will hold the Owner Trust Estate in trust upon and
subject to the conditions set forth herein for the use and benefit of the Certificateholders, subject to the obligations of the Trust under the Transaction Documents. It is the intention of the parties hereto that (i) the Trust constitute a
statutory trust under the Statutory Trust Statute and that this Trust Agreement constitute the governing instrument of such statutory trust and (ii) solely for income and franchise tax purposes, the Trust shall be treated (A) if it has one
beneficial owner, as a non-entity and (B) if it has more than one beneficial owner, as a partnership, with the assets of the partnership being the Receivables and other assets held by the Trust, the
partners of the partnership being the Certificateholders and the Notes constituting indebtedness of the partnership. Unless otherwise required by the appropriate tax authorities, the Trust shall file or cause to be filed annual or other necessary
returns, reports and other forms consistent with the characterization of the Trust either as a nonentity or as a partnership for such tax purposes. Effective as of the date hereof, the Owner Trustee shall have all rights, powers and duties set forth
herein and in the Statutory Trust Statute with respect to accomplishing the purposes of the Trust. The parties have caused the filing of the Certificate of Trust with the Secretary of State. If it is determined that, contrary to the intent of the
parties hereto and the position of the Certificateholder, the Trust has “gross receipts” for purposes of the Margin Tax, it is the intention of the parties hereto that the Trust be treated as a “passive entity” for purposes of
the Margin Tax, formed to hold assets to facilitate securitization transactions in a manner similar to grantor trusts and real estate mortgage 

  
 3 

 
investment conduits as defined by Section 860D of the Code. The Depositor, and the Certificateholders by acceptance of a Certificate, agree that if it is determined that, contrary to the
intent of the parties hereto and the position of the Certificateholder, the Trust has “gross receipts” for purposes of the Margin Tax, they will, unless otherwise required by law, treat the Trust as a “passive entity” for
purposes of the Margin Tax and will not, unless otherwise required by law, take any action to include the Trust as part of an affiliated group engaged in a unitary business (as such terms are used in the Margin Tax). Notwithstanding anything to the
contrary contained herein, nothing in this Trust Agreement should be read to imply that the Trust is doing business in Texas or has sufficient nexus with Texas in order for the Margin Tax to apply to the Trust. 

Section 2.7 Liability of Certificateholders. The Certificateholders shall be entitled to the same limitation of personal liability
extended to stockholders of private corporations organized under the General Corporation Law of the State of Delaware. 
 Section 2.8
Title to Trust Property. Legal title to the entirety of the Owner Trust Estate shall be vested at all times in the Trust as a separate legal entity, except where applicable law in any jurisdiction requires title to any part of the Owner Trust
Estate to be vested in a trustee or trustees, in which case title shall be deemed to be vested in the Owner Trustee, a co-trustee or a separate trustee, as the case may be; provided, that concurrently with or
prior to title being deemed to be vested in a co-trustee or a separate trustee, such trustee must provide a written grant of a security interest in the Owner Trust Estate to the Indenture Trustee and must
authorize the filing of a financing statement to perfect the Indenture Trustee’s security interest. 
 Section 2.9 Situs of
Trust. The Trust shall be located and administered in the State of Delaware or the State of New York. All bank accounts maintained by the Owner Trustee on behalf of the Trust shall be located in the State of Delaware or the State of New York.
The Trust shall not have any employees in any State other than the State of Delaware; provided, however, that nothing herein shall restrict or prohibit the Owner Trustee from having employees within or without the State of Delaware.
Payments will be received by the Trust only in the State of Delaware or the State of New York, and payments will be made by the Trust only from the State of Delaware or the State of New York. The principal office of the Trust will be at the
Corporate Trust Office in the State of Delaware. 
 Section 2.10 Representations and Warranties of the Depositor. The Depositor
hereby represents and warrants to the Owner Trustee that: 
 (i) the Depositor has been duly organized and is validly
existing as a limited liability company in good standing under the laws of the State of Delaware, has the power, authority and legal right to own its properties and to conduct its business as such properties are currently owned and such business is
currently conducted, and has the power, authority and legal right to acquire, own and sell the Receivables; 
 (ii) the
Depositor is duly qualified to do business as a foreign limited liability company in good standing and has obtained all necessary licenses and approvals in each jurisdiction in which the failure to so qualify or to obtain such licenses and approvals
would materially and adversely affect the performance by the Depositor of its 

  
 4 

 
obligations under, or the validity or enforceability of, this Trust Agreement, any of the other Transaction Documents to which the Depositor is a party, the Receivables, the Notes or the
Certificates; 
 (iii) the Depositor has the power and authority to execute, deliver and perform its obligations under this
Trust Agreement and the other Transaction Documents to which it is a party, and the Depositor has the power and authority to sell, assign, transfer and convey the property to be sold and transferred to and deposited with the Trust and has duly
authorized such transfer and deposit by all necessary limited liability company action, and the execution, delivery and performance of this Trust Agreement and the other Transaction Documents to which the Depositor is a party have been duly
authorized by the Depositor by all necessary limited liability company action; 
 (iv) the execution, delivery and
performance by the Depositor of this Trust Agreement and the other Transaction Documents to which the Depositor is a party, the consummation of the transactions contemplated hereby and thereby and the fulfillment of the terms hereof and thereof will
not conflict with, result in a breach of any of the terms and provisions of or constitute (with or without notice or lapse of time or both) a default under the certificate of formation or limited liability company agreement of the Depositor or any
material indenture, agreement, mortgage, deed of trust or other instrument to which the Depositor is a party or by which the Depositor is bound or to which any of its properties are subject, or result in the creation or imposition of any lien upon
any of its properties pursuant to the terms of any such indenture, agreement, mortgage, deed of trust or other instrument (other than pursuant to this Trust Agreement), or violate any law, order, rule or regulation applicable to the Depositor or its
properties of any federal or State regulatory body, court, administrative agency or other governmental instrumentality having jurisdiction over the Depositor or any of its properties; 

(v) there are no proceedings or investigations pending or, to the knowledge of the Depositor, threatened against the Depositor
before any court, regulatory body, administrative agency or other governmental instrumentality having jurisdiction over the Depositor or its properties (A) asserting the invalidity of this Trust Agreement, the Sale and Servicing Agreement, the
Indenture, any of the other Transaction Documents, the Notes or the Certificates, (B) seeking to prevent the issuance of the Notes or the Certificates or the consummation of any of the transactions contemplated by this Trust Agreement, the Sale
and Servicing Agreement, the Indenture or any of the other Transaction Documents, (C) seeking any determination or ruling that would materially and adversely affect the performance by the Depositor of its obligations under, or the validity or
enforceability of, this Trust Agreement, the Sale and Servicing Agreement, the Indenture, any of the other Transaction Documents, the Receivables, the Notes or the Certificates, or (D) that would adversely affect the federal tax attributes or
Applicable Tax State franchise or income tax attributes of the Trust or of the Notes or the Certificates; and 
 (vi) the
representations and warranties of the Depositor in Section 3.1 of the Receivables Purchase Agreement are true and correct. 

  
 5 

 Section 2.11 Federal Income Tax Matters. The Certificateholders acknowledge that
it is their intent and that they understand it is the intent of the Depositor and the Servicer that, for purposes of federal income, State and local income and franchise tax and any other income taxes, the Trust will be treated either as a
disregarded entity under Treasury Regulation Section 301.7701-3 (to the extent the Certificates are beneficially owned by one person) or as a partnership (to the extent the Certificates are owned by two
or more persons), and that the Certificateholders will be treated as partners in that partnership. The Certificateholders by acceptance of a Certificate agree to such treatment and agree to take no action inconsistent with such treatment. For each
calendar quarter, other than periods in which there is only one Certificateholder: 
 (i) net income of the Trust for any
calendar quarter as determined for federal income tax purposes (and each item of income, gain, credit, loss or deduction entering into the computation thereof) shall be allocated among the Certificateholders as of the first day following the end of
such quarter in proportion to their Certificate Percentage Interest on such date; and 
 (ii) net losses of the Trust, if
any, for any calendar quarter as determined for federal income tax purposes (and each item of income, gain, credit, loss or deduction entering into the computation thereof) shall be allocated among the Certificateholders as of the first day
following the end of such quarter in proportion to their Certificate Percentage Interest on such date. 
 The Depositor is authorized to
modify the allocations in this Section 2.11 if necessary or appropriate, in its sole discretion, for the allocations to reflect fairly the economic income, gain, credit, loss or deduction to the Certificateholders or as otherwise required by
the Code. 
 ARTICLE III 

CERTIFICATES AND TRANSFER OF INTERESTS 

Section 3.1 Initial Ownership. Upon the formation of the Trust by the contribution by the Depositor pursuant to Section 2.5
and until the issuance of the Certificates, the Depositor shall be the sole beneficiary of the Trust. 
 Section 3.2 The
Certificates. The Certificates shall be issued in one or more registered, definitive, physical certificates, substantially in the form set forth in Exhibit A. The Certificates may be in printed or typewritten form and shall be executed on behalf
of the Trust by manual or facsimile signature of an Authorized Officer of the Owner Trustee. Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures shall have been affixed, authorized to
sign on behalf of the Trust, shall be validly issued and entitled to the benefits of this Trust Agreement, notwithstanding that such individuals or any of them shall have ceased to be so authorized prior to the authentication and delivery of such
Certificates or did not hold such offices at the date of authentication and delivery of such Certificates. 

  
 6 

 If Transfer of the Certificates is permitted pursuant to this Section 3.2 and
Section 3.4, a transferee of a Certificate shall become a Certificateholder, and shall be entitled to the rights and subject to the obligations of a Certificateholder hereunder upon such transferee’s acceptance of a Certificate duly
registered in such transferee’s name pursuant to Section 3.4. 
 Section 3.3 Authentication of Certificates.
Concurrently with the initial sale of the Receivables to the Trust pursuant to the Sale and Servicing Agreement, the Owner Trustee shall cause the Certificates to be executed on behalf of the Trust, authenticated and delivered to or upon the written
order of the Depositor, signed by its president, any vice president, any assistant vice president, its treasurer, any assistant treasurer, its secretary or any assistant secretary, without further limited liability company action by the Depositor.
No Certificate shall entitle its Holder to any benefit under this Trust Agreement, or shall be valid for any purpose, unless there shall appear on such Certificate a certificate of authentication substantially in the form set forth in Exhibit A
executed by the Owner Trustee by manual signature, which authentication shall constitute conclusive evidence that such Certificate shall have been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their
authentication. Upon issuance, authentication and delivery pursuant to the terms hereof, the Certificates will be entitled to the benefits of this Trust Agreement. 

Section 3.4 Registration of Certificates; Transfer and Exchange of Certificates. 

(a) The Indenture Trustee initially shall be the registrar (the “Certificate Registrar”) for the purpose of registering
Certificates and Transfers of Certificates as herein provided. The Certificate Registrar shall cause to be kept, at the office or agency maintained pursuant to Section 3.8, a register (the “Certificate Register”) in which,
subject to such reasonable regulations as it may prescribe, the Certificate Registrar shall provide for the registration of Certificates and the registration of Transfers of Certificates. Upon any resignation of any Certificate Registrar, the Owner
Trustee shall, upon receipt of written instructions from the Depositor, promptly appoint a successor. 
 (b) The Certificates may not be
acquired with the plan assets of any (i) “employee benefit plan” (as defined in Section 3(3) of ERISA) that is subject to Title I of ERISA, (ii) “plan” described in Section 4975(e)(1) of the Code, including individual
retirement accounts and Keogh plans, that is subject to the provisions of Section 4975 of the Code, (iii) entity whose underlying assets include “plan assets” within the meaning of the Plan Asset Regulation by reason of an
employee benefit plan’s or plan’s investment in such entity or (iv) employee benefit plan or arrangement not subject to Title I of ERISA or Section 4975 of the Code (each of (i) through (iv), a “Plan”),
other than any Plan that is not subject to Title I of ERISA or Section 4975 of the Code and whose acquisition of a Certificate would not constitute or result in a violation of any applicable law that is substantially similar to Title I of ERISA
or Section 4975 of the Code (“Similar Law”). Each Certificateholder, by its acceptance of a Certificate, shall be deemed to have represented and warranted that such Certificateholder is either (i) not a Plan and is not a
Person acting on behalf of a Plan or a Person using the assets of a Plan to effect the transfer of such Certificate, or (ii) a Plan that is not subject to Title I of ERISA or Section 4975 of the Code and whose acquisition of a Certificate
would not constitute or result in a violation under any Similar Law. 

  
 7 

 Any person who is not an affiliate of the Seller and acquires more than 49.9% of the
Certificates will be deemed to represent that it is not a “party in interest” (within the meaning of ERISA) or a “disqualified person” (within the meaning of Section 4975(e)(2) of the Code) with respect to any Plan, other
than a Plan that it sponsors for the benefit of its employees, and that no Plan with respect to which it is a party in interest or disqualified person has or will acquire any interest in the Notes. 

To the extent permitted under applicable law (including, but not limited to, ERISA), neither the Owner Trustee nor the Certificate Registrar
shall be under any liability to any Person for any registration of transfer of any Certificate that is in fact not permitted or for taking any other action with respect to such Certificate under the provisions of this Trust Agreement so long as such
transfer was registered by the Owner Trustee or the Certificate Registrar in accordance with this Trust Agreement. 
 (c) Upon surrender for
registration of Transfer of any Certificate at the office or agency of the Certificate Registrar to be maintained as provided in Section 3.8, and upon compliance with any provisions of this Trust Agreement relating to such Transfer, the Owner
Trustee shall execute on behalf of the Trust and the Owner Trustee shall authenticate and deliver to the Certificateholder making such surrender, in the name of the designated transferee or transferees, one or more new Certificates in any authorized
denomination evidencing the same aggregate interest in the Trust. Each Certificate presented or surrendered for registration of Transfer or exchange shall be accompanied by a written instrument of transfer and accompanied by IRS Form W-8BEN-E, W-8ECI or W-9, as applicable, and such other documentation as may be reasonably
required by the Owner Trustee in order to comply with Applicable Anti-Money Laundering Law, each in a form satisfactory to the Owner Trustee and the Certificate Registrar, duly executed by the Certificateholder or his attorney duly authorized in
writing. Each Certificate presented or surrendered for registration of Transfer or exchange shall be canceled and subsequently disposed of by the Certificate Registrar in accordance with its customary practice. No service charge shall be made for
any registration of Transfer or exchange of Certificates, but the Owner Trustee or the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any Transfer or
exchange of Certificates. Further, in the event of any subsequent transfer of a Certificate (or any interest therein), each owner of a beneficial interest shall comply with Section 1446(f) of the Code (including with respect to deducting and
withholding from the purchase price paid in respect of such Certificate unless the transferee obtained a certificate providing for an exemption from such withholding). 

(d) As a condition to the registration of any Transfer of any Certificate: 

(i) the prospective transferee shall be required to represent in writing to the Owner Trustee, the Depositor and the
Certificate Registrar that it has neither acquired nor will it transfer any Certificate it purchases (or any interest therein) or cause any such Certificate (or any interest therein) to be marketed on or through an “established securities
market” within the meaning of Section 7704(b)(1) of the Code, including, without limitation, an over-the-counter-market or an interdealer quotation system that
regularly disseminates firm buy or sell quotations; 

  
 8 

 (ii) the prospective transferee shall be required to represent in writing to
the Owner Trustee, the Depositor and the Certificate Registrar that it either (A) is not, and will not become, a partnership, Subchapter S corporation or grantor trust for United States federal income tax purposes or (B) is such an entity,
but none of the direct or indirect beneficial owners of any of the interests in such transferee have allowed or caused, or will allow or cause, 50% or more (or such other percentage as the transferor may establish prior to the time of such proposed
transfer) of the value of such interests to be attributable to such transferee’s ownership of Certificates; 
 (iii) the
prospective transferee shall be required to represent in writing to the Owner Trustee, the Depositor and the Certificate Registrar that it is either (i) not a Plan and is not a Person acting on behalf of a Plan or a Person using the assets of a
Plan to effect the transfer of such Certificate, or (ii) a Plan that is not subject to Title I of ERISA or Section 4975 of the Code and whose acquisition of a Certificate would not constitute or result in a violation under any Similar Law;

 (iv) the Certificateholder provides to the Owner Trustee and the Depositor an opinion of independent counsel that such
action will not cause the Issuer to be treated as an association (or publicly traded partnership) taxable as a corporation for federal income tax purposes; 

(v) such transferee or assignee agrees to take positions for tax purposes consistent with the tax positions agreed to be taken
by the Certificateholder; and 
 (vi) in connection with any transfer of less than all of the interests in the Certificates,
the transferor and transferee shall specify the respective interests in the Certificates to be held by the transferor and transferee, which interests may be determined by a formula or on any other basis agreed by the transferor and transferee. No
Certificate (other than the Certificates issued to and held by the Depositor) may be subdivided upon transfer or exchange in a manner such that the resulting Certificate represents less than a 2.50% fractional undivided interest in the Issuer (or
such other amount as the Depositor may determine in order to prevent the Issuer from being treated as a “publicly traded partnership” under Section 7704 of the Code). 

(e) No Certificateholder shall Transfer any Certificate initially held by it unless such Transfer is made pursuant to an effective registration
statement or otherwise in accordance with the requirements under the Securities Act and effective registration or qualification under applicable State securities laws, or is made in a transaction which does not require such registration or
qualification. If a Transfer is to be made in reliance upon an exemption from the Securities Act and under applicable State securities laws, (i) the Certificate Registrar may require an Opinion of Counsel reasonably satisfactory to the
Certificate Registrar and the Depositor substantially to the effect that such Transfer may be made pursuant to an exemption from the Securities Act and applicable State securities laws and describing the applicable exemption and the basis therefor,
which Opinion of Counsel shall not be an expense of the Certificate Registrar, the Depositor or the Owner Trustee, and (ii) the Certificate Registrar may require the transferee to execute a certification acceptable to and in form and substance

  
 9 

 
satisfactory to the Certificate Registrar and the Depositor setting forth the facts surrounding such Transfer. 

(f) No Transfer of any Certificate shall be permitted, recognized or recorded unless the Depositor has consented in writing to such Transfer,
which consent may be withheld in the sole discretion of the Depositor; provided, however, that no such consent of the Depositor shall be required where the proposed transferee is, and at the time of such Transfer will be, a
Certificateholder. 
 (g) During the period described in 17 CFR Part 246.12(f)(1), no Certificateholder may Transfer any Certificate until
the expiration of such period; provided, that, during such period, such Certificateholder may Transfer any Certificate to CarMax or any “majority-owned affiliate” (as such term is defined in 17 CFR Part 246.2) of CarMax in
accordance with the restrictions contained in 17 CFR Part 246.12. Any purported transfer of a Certificate not in accordance with this Section 3.4(g) shall be null and void and shall not be given effect for any purpose whatsoever. 

Section 3.5 Mutilated, Destroyed, Lost or Stolen Certificates. 

(a) If (i) any mutilated Certificate is surrendered to the Certificate Registrar, or the Certificate Registrar receives evidence to its
satisfaction of the destruction, loss or theft of any Certificate, and (ii) there is delivered to the Certificate Registrar and the Owner Trustee such security or indemnity as may be required by them to hold each of the Trust, the Certificate
Registrar and the Owner Trustee harmless, then, in the absence of notice to the Trust, the Certificate Registrar or the Owner Trustee that such Certificate has been acquired by a “protected purchaser” (as defined in the Relevant UCC), the
Owner Trustee shall execute on behalf of the Trust and the Owner Trustee shall authenticate and deliver, in exchange for, or in lieu of, any such mutilated, destroyed, lost or stolen Certificate, as the case may be, a replacement Certificate, as the
case may be, of like tenor and Certificate Percentage Interest. If, after the delivery of such replacement Certificate or payment of a destroyed, lost or stolen Certificate pursuant to the proviso to the preceding sentence, a “protected
purchaser” (as defined in the Relevant UCC) of the original Certificate in lieu of which such replacement Certificate was issued presents for payment such original Certificate, the Trust and the Owner Trustee shall be entitled to recover such
replacement Certificate (or such payment) from the Person to whom such replacement Certificate was delivered or any Person taking such replacement Certificate from such Person to whom such replacement Certificate was delivered or any assignee of
such Person, except a “protected purchaser” (as defined in the Relevant UCC), and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Trust or the
Owner Trustee in connection therewith. 
 (b) Upon the issuance of any replacement Certificate under this Section 3.5, the Trust may
require the payment by the Holder of such Certificate of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with such issuance and any other reasonable expenses (including the fees and expenses of the
Owner Trustee) related thereto. 

  
 10 

 (c) Every replacement Certificate issued pursuant to this Section 3.5 in replacement of
any mutilated, destroyed, lost or stolen Certificate shall constitute an original additional contractual obligation of the Trust, whether or not the mutilated, destroyed, lost or stolen Certificate shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Trust Agreement equally and proportionately with any and all other Certificates duly issued hereunder. 

(d) The provisions of this Section 3.5 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect
to the replacement or payment of mutilated, destroyed, lost or stolen Certificates. 
 Section 3.6 Persons Deemed Owners. Prior
to due presentation of a Certificate for registration of transfer, the Owner Trustee, the Certificate Registrar and any Paying Agent may treat the Person in whose name such Certificate is registered in the Certificate Register (as of the day of
determination) as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 5.2 and for all other purposes whatsoever, and none of the Owner Trustee, the Certificate Registrar or any Paying Agent shall be
bound by any notice to the contrary. 
 Section 3.7 Access to List of Certificateholders’ Names and
Addresses. The Certificate Registrar shall furnish or cause to be furnished to the Servicer and the Depositor, or to the Indenture Trustee or the Owner Trustee, within fifteen (15) days after receipt by the Certificate Registrar of a
written request therefor from the Servicer, the Depositor or the Indenture Trustee or the Owner Trustee, as the case may be, a list, in such form as the requesting party may reasonably require, of the names and addresses of the Certificateholders as
of the most recent Record Date. If three or more Certificateholders or one or more Holders of Certificates evidencing not less than 25% of the aggregate Certificate Percentage Interest apply in writing to the Certificate Registrar, and such
application states that the applicants desire to communicate with other Certificateholders with respect to their rights under this Trust Agreement or under the Certificates and such application is accompanied by a copy of the communication that such
applicants propose to transmit, then the Certificate Registrar shall, within five (5) Business Days after the receipt of such application, afford such applicants access during normal business hours to the current list of Certificateholders.
Each Certificateholder, by receiving and holding a Certificate, shall be deemed to have agreed not to hold any of the Depositor, the Certificate Registrar or the Owner Trustee accountable by reason of the disclosure of its name and address,
regardless of the source from which such information was derived. 
 Section 3.8 Maintenance of Office or Agency. The
Certificate Registrar shall maintain in St. Paul, Minnesota, an office or offices or agency or agencies where Certificates may be surrendered for registration of Transfer or exchange and where notices and demands to or upon the Certificate Registrar
in respect of the Certificates and the Transaction Documents may be served. The Certificate Registrar shall give prompt written notice to the Depositor, the Owner Trustee and the Certificateholders of any change in the location of the Certificate
Registrar or any such office or agency. 
 Section 3.9 Appointment of Paying Agent. The Paying Agent shall make distributions to
Certificateholders from the Certificate Payment Account pursuant to Section 5.2 

  
 11 

 
and shall report the amounts of such distributions to the Owner Trustee. Any Paying Agent shall have the revocable power to withdraw funds from the Certificate Payment Account for the purpose of
making the distributions referred to above. The Owner Trustee may revoke such power and remove the Paying Agent if the Owner Trustee determines in its sole discretion that the Paying Agent shall have failed to perform its obligations under this
Trust Agreement in any material respect. The Paying Agent shall initially be the Indenture Trustee and any co-paying agent chosen by the Indenture Trustee. The Indenture Trustee shall be permitted to resign as
Paying Agent upon thirty (30) days’ written notice to the Depositor and the Owner Trustee. In the event that the Indenture Trustee shall no longer be the Paying Agent, the Owner Trustee, upon receipt of written instructions from the
Depositor, shall appoint a successor to act as Paying Agent (which shall be a bank or trust company). The Owner Trustee shall direct such successor Paying Agent or any additional Paying Agent appointed by the Owner Trustee to execute and deliver to
the Owner Trustee an instrument in which such successor Paying Agent or additional Paying Agent shall agree with the Owner Trustee that as Paying Agent, such successor Paying Agent or additional Paying Agent will hold all sums, if any, held by it
for payment to the Certificateholders in trust for the benefit of the Certificateholders entitled thereto until such sums shall be paid to such Certificateholders. The Paying Agent shall return all unclaimed funds to the Owner Trustee and upon
removal of a Paying Agent such Paying Agent shall also return all funds in its possession to the Owner Trustee. Any reference in this Trust Agreement to the Paying Agent shall include any co-paying agent
unless the context requires otherwise. 
 Section 3.10 Restrictions on Note Acquisitions. No transfer of a Certificate (or
interest therein) shall be permitted (nor shall a Certificate be so held) if (i) it causes the Issuer to be a Section 385 Controlled Partnership (i.e., 80 percent or more of the Issuer’s ownership interests are owned, directly or
indirectly, by one or more members of a Section 385 Expanded Group) that has an expanded group partner (within the meaning of Treasury Regulation Section 1.385-3(g)(12)) which is a Domestic
Corporation and (ii) either (x) a member of such Section 385 Expanded Group owns any Notes or (y) a Section 385 Controlled Partnership of such Section 385 Expanded Group owns any Notes (in the case of clause (x), unless such
member, or in the case of clause (y), unless each member of the Section 385 Expanded Group that is a partner in the Section 385 Controlled Partnership, is a member of the consolidated group (as described in Treasury Regulation section 1.1502-1(h)) which includes such Domestic Corporation). No transfer of a Certificate (or interest therein) shall be permitted (nor shall a Certificate be so held) if (i) it results in the Issuer becoming an
entity disregarded as separate from a Domestic Corporation for United States federal income tax purposes and (ii) either (x) a member of a Section 385 Expanded Group that includes such Domestic Corporation owns any Notes or (y) a
Section 385 Controlled Partnership of such Section 385 Expanded Group owns any Notes (in the case of clause (x), unless such member, or in the case of clause (y), unless each member of the Section 385 Expanded Group that is a partner
in the Section 385 Controlled Partnership, is a member of the consolidated group (as described in Treasury Regulation section 1.1502-1(h)) which includes such Domestic Corporation). For purposes of
determining the Issuer’s ownership interests in this paragraph, any Retained Notes shall be taken into account either as debt interests or ownership interests based on whichever treatment, if any, would result in the Issuer as a
Section 385 Controlled Partnership or a disregarded entity for purposes of applying this paragraph’s restriction (it being understood that if the Retained Notes are taken into account as ownership interests for this purpose then the
Retained Notes are not also considered Notes for the Note ownership restriction of this paragraph).

Section 4.3 Action by Certificateholders with Respect to Bankruptcy. The Owner Trustee shall not have the power to commence a
voluntary proceeding in bankruptcy relating to the Trust unless (i) the Notes have been paid in full and (ii) each Certificateholder approves of such commencement in writing in advance and delivers to the Owner Trustee a certificate
certifying that such Person reasonably believes that the Trust is insolvent. 
 Section 4.4 Restrictions on
Certificateholders’ Power. The Certificateholders shall not direct the Owner Trustee to take or refrain from taking any action if such action or inaction would be contrary to any obligation of the Trust or the Owner Trustee
under this Trust Agreement or any of the other Transaction Documents or would be contrary to Section 2.3, nor shall the Owner Trustee be obligated to follow any such direction, if given. 

Section 4.5 Majority Control. Except as expressly provided herein, any action that may be taken by the Certificateholders under
this Trust Agreement may be taken by the Holders of Certificates evidencing not less than 51% of the aggregate Certificate Percentage Interest. Except as expressly provided herein, any written notice of the Certificateholders delivered pursuant to

ARTICLE V 
 APPLICATION OF TRUST
FUNDS; CERTAIN DUTIES 
 Section 5.1 Establishment of Certificate Payment Account. Pursuant to Section 4.1 of the Sale and
Servicing Agreement, the Servicer has agreed to establish, on or before the Closing Date, and maintain in the name of the Indenture Trustee at an Eligible Institution (which shall initially be the Indenture Trustee) a segregated trust account
designated as the “CarMax Auto Owner Trust 2021-1 Trust Account” (the “Certificate Payment Account”). The Certificate Payment Account shall be held in trust for the benefit of the
Certificateholders. Except as expressly provided in Section 3.9, the Certificate Payment Account shall be under the sole dominion and control of the Indenture Trustee. All monies deposited from time to time in the Certificate Payment Account
pursuant to the Sale and Servicing Agreement or the Indenture shall be applied as provided in this Trust Agreement, the Sale and Servicing Agreement and the Indenture. The amounts on deposit in the Certificate Payment Account shall not be invested.

 Section 5.2 Application of Trust Funds. 

(a) On each Distribution Date, upon receipt of written instructions from the Servicer pursuant to Section 4.1(c) of the Sale and Servicing
Agreement, the Paying Agent shall distribute to the Certificateholders, in proportion to each Certificateholder’s Certificate 

  
 14 

 
Percentage Interest, amounts deposited in the Certificate Payment Account on such Distribution Date pursuant to Section 4.1(c) of the Sale and Servicing Agreement and Section 2.8 of the
Indenture with respect to such Distribution Date. 
 (b) On each Distribution Date, the Paying Agent shall, or, if the Indenture Trustee is
not the Paying Agent, the Indenture Trustee shall direct the Paying Agent to, make available to each Certificateholder the statement provided to the Indenture Trustee by the Servicer pursuant to Section 4.9 of the Sale and Servicing Agreement
with respect to such Distribution Date. 
 (c) In the event that any withholding tax is imposed on any Trust payment (or any allocation of
income) to a Certificateholder, such tax shall reduce the amount otherwise distributable to the Certificateholder in accordance with this Section 5.2. The Owner Trustee and each Paying Agent are hereby authorized and directed to retain from
amounts otherwise distributable to the Certificateholders sufficient funds for the payment of any such withholding tax that is legally owed by the Trust (but such authorization shall not prevent the Owner Trustee from contesting any such tax in
appropriate proceedings, and withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). The amount of any withholding tax imposed with respect to a Certificateholder shall be treated as cash distributed to such
Certificateholder at the time it is withheld by the Trust and remitted to the appropriate taxing authority. If there is a possibility that withholding tax is payable with respect to a distribution (such as a distribution to a non-U.S. Certificateholder), the Owner Trustee or the Paying Agent may withhold such amounts in accordance with this Section 5.2. If a Certificateholder wishes to apply for a refund of any such withholding tax,
the Owner Trustee shall reasonably cooperate with such Certificateholder in making such claim so long as such Certificateholder agrees to reimburse the Owner Trustee for any
out-of-pocket expenses incurred. 
 Section 5.3
Method of Payment. Subject to Section 5.2(c), distributions required to be made to Certificateholders on any Distribution Date shall be made to each Certificateholder of record on the preceding Record Date either by wire transfer, in
immediately available funds, to the account of such Holder at a bank or other entity having appropriate facilities therefor, if such Certificateholder shall have provided to the Certificate Registrar and the Paying Agent appropriate written
instructions at least five (5) Business Days prior to such Distribution Date and such Certificateholder is the Depositor or, if not, by check mailed to such Certificateholder at the address of such Holder appearing in the Certificate Register.
Notwithstanding the foregoing, the final distribution in respect of any Certificate (whether on the Final Scheduled Maturity Date or otherwise) will be payable only upon presentation and surrender of such Certificate at the office or agency
maintained for that purpose by the Certificate Registrar pursuant to Section 3.8. 
 Section 5.4 No Segregation of Monies; No
Interest. Subject to Section 5.1 and Section 5.2, monies received by the Owner Trustee hereunder need not be segregated in any manner except to the extent required by law, the Indenture or the Sale and Servicing Agreement and may be
deposited under such general conditions as may be prescribed by law, and the Owner Trustee shall not be liable for any interest thereon. 

  
 15 

 Section 5.5 Accounting and Reports to the Noteholders, Certificateholders, the
Internal Revenue Service and Others. The Owner Trustee shall, based on information provided by the Seller, (i) maintain (or cause to be maintained) the books of the Trust on the basis of a fiscal year ending on the last day of February and
based on the accrual method of accounting, (ii) deliver to each Certificateholder, as may be required by the Code and applicable Treasury Regulations, such information as may be required (including Schedule
K-1) to enable such Certificateholder to prepare its federal and State income tax returns, (iii) file such tax returns relating to the Trust (including a partnership information return, IRS Form 1065) and
make such elections as may from time to time be required or appropriate under any applicable State or federal statute or rule or regulation thereunder so as to maintain the Trust’s characterization as a partnership for federal income tax
purposes, (iv) cause such tax returns to be signed in the manner required by law and (v) collect or cause to be collected any withholding tax as described in and in accordance with Section 5.2(c) with respect to income or
distributions to Certificateholders. The Owner Trustee, on behalf of the Trust, shall elect under Section 1278 of the Code to include in income currently any market discount that accrues with respect to the Receivables. The Owner Trustee, on
behalf of the Trust, shall not make the election provided under Section 754 of the Code. 
 The Owner Trustee may satisfy its
obligations with respect to this Section 5.5 by retaining, on behalf of the Trust, at the expense of the Seller, a firm of independent public accountants (the “Accountants”) selected by the Seller. The Owner Trustee, on behalf
of the Trust, may require the Accountants to provide to the Owner Trustee, on or before March 15, 2022, a letter in form and substance satisfactory to the Owner Trustee as to whether any federal tax withholding on Certificates is then required
and, if required, the procedures to be followed with respect thereto to comply with the requirements of the Code. The Accountants shall be required to update such letter in each instance that any additional tax withholding is subsequently required
or any previously required tax withholding shall no longer be required. The Owner Trustee shall be deemed to have discharged its obligations pursuant to this Section 5.5 upon its retention of the Accountants, and the Owner Trustee shall not
have any liability with respect to the default or misconduct of the Accountants. 
 Section 5.6 Signature on Returns; Partnership
Representative. 
 (a) The Owner Trustee shall sign, on behalf of the Trust, the tax returns of the Trust. 

(b) If the Trust entity were classified as a partnership for federal income tax purposes, then the Depositor (or a U.S. Affiliate of the
Depositor if the Depositor is ineligible) shall be designated the “partnership representative” of the Trust under Section 6223(a) of the Code and any corresponding provision of State law (and as the tax matters partner for any
applicable State tax purposes) to the extent permitted under law. The Issuer shall (or the Depositor shall cause the Issuer to, or the Depositor shall instruct the Administrator on behalf of the Issuer to), to the extent eligible, make the election
under Section 6221(b) of the Code (and any corresponding provision of State law) with respect to determinations of adjustments at the partnership level and take any other action such as disclosures and notifications necessary to effectuate such
election (including working with the Depositor to designate any designated individual required under the law). If the election described in the preceding sentence is not 

  
 16 

 
available, to the extent applicable, the Issuer shall (or the Depositor shall cause the Issuer to, or the Depositor shall instruct the Administrator on behalf of the Issuer to) make the election
under Section 6226(a) of the Code (and any corresponding provision of State law) with respect to the alternative to payment of imputed underpayment by partnership and take any other action such as filings, disclosures and notifications
necessary to effectuate such election. Notwithstanding the foregoing, the Issuer, Depositor and Administrator are each authorized, in its sole discretion, to make any available election related to Sections 6221 through 6241 of the Code (and any
corresponding provision of State law) and take any action it deems necessary or appropriate to comply with the requirements of Sections 6221 through 6241 of the Code and conduct the Issuer’s affairs under Sections 6221 through 6241 of the Code
(and any corresponding provision of State law). Each Certificateholder and, if different, each beneficial owner of a Certificate, shall promptly provide the Issuer, Depositor and Administrator any requested information, documentation or material to
enable the Issuer to make any of the elections described in this clause (b) and otherwise comply with Sections 6221 through 6241 of the Code (and any corresponding provision of State law). Each Certificate Owner and, if different, each
beneficial owner of a Certificate shall hold the Issuer and its affiliates harmless for any expenses or losses (i) resulting from a beneficial owner of a Certificate not properly taking into account or paying its allocated adjustment or
liability under Section 6226 of the Code (or any corresponding provision of State law) or (ii) suffered that are attributable to the management or defense of an audit under Sections 6221 through 6241 of the Code or otherwise due to actions
it takes with respect to and to comply with the rules under Sections 6221 through 6241 of the Code (or any corresponding provision of State law). 

ARTICLE VI 
 AUTHORITY AND DUTIES
OF OWNER TRUSTEE 
 Section 6.1 General Authority. The Owner Trustee is authorized and directed to execute and deliver the
Transaction Documents to which the Trust is to be a party and each certificate or other document attached as an exhibit to or contemplated by the Transaction Documents to which the Trust is to be a party, in each case in such form as the Depositor
shall approve, as evidenced conclusively by the Owner Trustee’s execution thereof and the Depositor’s execution of this Trust Agreement, and to direct the Indenture Trustee to authenticate and deliver Notes in the aggregate principal
amount of $1,500,000,000 (comprising $255,000,000 in aggregate principal amount of Class A-1 Notes, $441,500,000 in aggregate principal amount of Class A-2a
Notes, $50,000,000 in aggregate principal amount of Class A-2b Notes, $522,500,000 in aggregate principal amount of Class A-3 Notes, $136,950,000 in aggregate

amount of Class D Notes). In addition to the foregoing, the Owner Trustee is authorized to take all actions required of the Trust pursuant to the Transaction Documents. The Owner Trustee is further authorized from time to time to take such
action on behalf of the Trust as is permitted by the Transaction Documents and which the Certificateholders, the Servicer or the Administrator recommends in writing with respect to the Transaction Documents, except to the extent that this Trust
Agreement expressly requires the consent of Certificateholders for such action. 

  
 17 

 Section 6.2 General Duties. It shall be the duty of the Owner Trustee to
discharge (or cause to be discharged) all of its responsibilities pursuant to the terms of this Trust Agreement and to administer the Trust for the benefit of the Certificateholders, subject to the lien of the Indenture and in accordance with the
provisions of this Trust Agreement. Notwithstanding the foregoing, the Owner Trustee shall be deemed to have discharged (or caused to be discharged) its duties and responsibilities hereunder to the extent the Administrator is required in the
Administration Agreement to perform any act or to discharge such duty of the Owner Trustee or the Trust hereunder or under any other Transaction Document, and the Owner Trustee shall not be held liable for the default or failure of the Administrator
to carry out its obligations under the Administration Agreement. The Owner Trustee shall not be charged with knowledge of any Event of Default unless either (i) a Responsible Officer shall have actual knowledge of such Event of Default or
(ii) written notice of such Event of Default shall have been given to the Owner Trustee in accordance with the provisions of this Trust Agreement. 

Section 6.3 Action upon Instruction. 

(a) Subject to Article IV, and in accordance with the terms of the Transaction Documents, the Certificateholders may, by written instruction,
direct the Owner Trustee in the management of the Trust. 
 (b) The Owner Trustee shall not be required to take any action under this Trust
Agreement or any other Transaction Document if the Owner Trustee shall have reasonably determined, or shall have been advised by counsel, that such action is likely to result in liability on the part of the Owner Trustee or is contrary to the terms
of this Trust Agreement or any other Transaction Document or is otherwise contrary to law. 
 (c) Subject to Article IV, whenever the Owner
Trustee is unable to decide between alternative courses of action permitted or required by the terms of this Trust Agreement or any other Transaction Document, the Owner Trustee shall promptly give notice (in such form as shall be appropriate under
the circumstances) to the Certificateholders requesting instruction as to the course of action to be adopted, and to the extent the Owner Trustee acts in good faith in accordance with any written instruction of the Certificateholders received, the
Owner Trustee shall not be liable on account of such action to any Person. If the Owner Trustee shall not have received appropriate written instruction within ten (10) days of such notice (or within such shorter period of time as reasonably may
be specified in such notice or may be necessary under the circumstances) it may, but shall be under no duty to, take or refrain from taking such action, not inconsistent with this Trust Agreement or the other Transaction Documents, as it shall deem
to be in the best interests of the Certificateholders, and shall have no liability to any Person for such action or inaction. 
 (d) Subject
to Article IV, in the event the Owner Trustee is unsure as to the application of any provision of this Trust Agreement or any other Transaction Document or any such provision is ambiguous as to its application, or is, or appears to be, in conflict
with any other applicable provision, or in the event that this Trust Agreement permits any determination by the Owner Trustee or is silent or is incomplete as to the course of action that the Owner Trustee is required to take with respect to a
particular set of facts, the Owner Trustee may give notice (in such form as shall be appropriate under the circumstances) to the Certificateholders 

  
 18 

 
requesting instruction and, to the extent that the Owner Trustee acts or refrains from acting in good faith in accordance with any such instruction received, the Owner Trustee shall not be
liable, on account of such action or inaction, to any Person. If the Owner Trustee shall not have received appropriate written instruction within ten (10) days of such notice (or within such shorter period of time as reasonably may be specified
in such notice or may be necessary under the circumstances) it may, but shall be under no duty to, take or refrain from taking such action not inconsistent with this Trust Agreement or the other Transaction Documents, as it shall deem to be in the
best interests of the Certificateholders and shall have no liability to any Person for such action or inaction. 
 Section 6.4 No
Duties Except as Specified in this Trust Agreement or in Instructions. The Owner Trustee shall not have any duty or obligation to manage, make any payment with respect to, register, record, sell, dispose of or otherwise deal with the Owner Trust
Estate, or to otherwise take or refrain from taking any action under, or in connection with, any document contemplated hereby to which the Owner Trustee or the Trust is a party, except as expressly provided by the terms of this Trust Agreement or in
any document or written instruction received by the Owner Trustee pursuant to Section 6.3, and no implied duties or obligations shall be read into this Trust Agreement or any other Transaction Document against the Owner Trustee. The Owner
Trustee shall have no responsibility for filing any financing or continuation statement in any public office at any time or otherwise to perfect or maintain the perfection of any security interest or lien granted to it hereunder or to prepare or
file any Commission filing for the Trust or to record this Trust Agreement or any other Transaction Document. The Owner Trustee shall not have any duty to (1) monitor, determine, or verify the unavailability or cessation of LIBOR (or other
applicable benchmark), or to determine whether or when there has occurred, or to give notice to any other transaction party of the occurrence of, any Benchmark Transition Event, (2) select, determine or designate any Benchmark Replacement, or
other successor or replacement benchmark index, or whether any conditions to the designation of such a rate have been satisfied, (3) select, determine or designate any Benchmark Replacement Adjustment, or other modifier to any replacement or
successor index, or (4) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing. The Owner Trustee shall not be liable for any inability, failure or delay
on its part to perform any of its duties set forth in this Trust Agreement or any other Transaction Document as a result of the unavailability of LIBOR (or any other applicable benchmark) or the absence of a designated Benchmark Replacement,
including as a result of any inability, delay, error or inaccuracy on the part of any other transaction party, in providing any direction, instruction, notice or information required or contemplated by this Trust Agreement or any other Transaction
Document and reasonably required for the performance of such duties. The Owner Trustee shall, however, at its own cost and expense, promptly take all action as may be necessary to discharge any lien (other than the lien of the Indenture) on any part
of the Owner Trust Estate that results from actions by, or claims against, the Owner Trustee in its individual capacity that are not related to the ownership or the administration of the Owner Trust Estate. 

Section 6.5 No Action Except Under Specified Documents or Instructions. The Owner Trustee shall not manage, control, use, sell,
dispose of or otherwise deal with any part of the Owner Trust Estate except (i) in accordance with the powers granted to and the authority conferred upon the Owner Trustee pursuant to this Trust Agreement, (ii) in accordance

  
 19 

 
with the other Transaction Documents to which the Trust is a party and (iii) in accordance with any document or written instruction delivered to the Owner Trustee pursuant to
Section 6.3. 
 Section 6.6 Restrictions. The Owner Trustee shall not take any action (i) that is inconsistent with
the purposes of the Trust set forth in Section 2.3 or (ii) that, to the actual knowledge of the Owner Trustee, would (A) affect the treatment of the Notes as indebtedness for federal income or Virginia income or franchise tax
purposes, (B) be deemed to cause a taxable exchange of the Notes for federal income or Virginia income or franchise tax purposes or (C) cause the Trust or any portion thereof to be taxable as an association or publicly traded partnership
taxable as a corporation for federal income or Virginia income or franchise tax purposes. The Certificateholders, the Depositor, the Administrator and the Servicer shall not direct the Owner Trustee to take action that would violate the provisions
of this Section 6.6. 
 Section 6.7 Instructions by Electronic Methods. The Owner Trustee is hereby authorized to rely upon
and comply with instructions and directions sent by e-mail, facsimile and other similar unsecured electronic methods (“Electronic Methods”) by persons believed by the Owner Trustee to be authorized
to give instructions and directions on behalf of the Depositor. The Owner Trustee shall have no duty or obligation to verify or confirm that the person who sent such instructions or directions is, in fact, a person authorized to give instructions or
directions on behalf of the Depositor (other than to verify that the signature on a facsimile is the signature of a person authorized to give instructions and directions on behalf of the Depositor), and the Owner Trustee shall have no liability for
any losses, liabilities, costs or expenses incurred or sustained by the Depositor as a result of such reliance upon or use of Electronic Methods to submit instructions and directions to the Owner Trustee, including the risk of the Owner Trustee
taking unauthorized instructions, and the risk of interception and misuse by third parties.

Demands to Repurchase Receivables. The Owner Trustee shall provide notice to CarMax and the Depositor as soon as practicable of all demands communicated to a Responsible Officer of the Owner Trustee for the repurchase or replacement of any
Receivable for breach of the representations and warranties concerning such Receivable. Subject to this Section 6.8, the Owner Trustee shall have no obligation to take any other action with respect to a demand. However, the
Owner Trustee shall, upon written request of either CarMax or the Depositor, provide notification to CarMax and the Depositor with respect to any actions taken by the Owner Trustee with respect to any such demand communicated to a Responsible
Officer of the Owner Trustee in respect of any Receivables, such notifications to be provided by the Owner Trustee as soon as practicable and in any event within five Business Days of such request or such other time frame as may be mutually agreed
to by the Owner Trustee and CarMax or the Depositor, as applicable. The Owner Trustee acknowledges and agrees that the purpose of this Section 6.8 is to facilitate compliance by CarMax and the Depositor with Rule 15Ga-1 under the Exchange Act, as amended, and Items 1104(e) and 1121(c) of Regulation AB (the “Repurchase Rules and Regulations”). The Owner Trustee acknowledges that interpretations of the
requirements of the Repurchase Rules and Regulations may change over time, whether due to interpretive guidance provided by the Commission or its staff, consensus among participants in the asset-backed securities markets, advice of counsel, or
otherwise, and agrees to comply with reasonable requests made by CarMax and the Depositor in good faith for delivery of information under these provisions on the basis of evolving interpretations of the Repurchase Rules and Regulations. The Owner
Trustee shall cooperate 

  
 20 

 
fully with CarMax and the Depositor to deliver any and all records and any other information in its actual possession that are reasonably requested in writing by CarMax or the Depositor and
necessary in the good faith determination of CarMax and the Depositor to permit them to comply with the provisions of the Repurchase Rules and Regulations. In no event shall the Owner Trustee have (i) any responsibility or liability in
connection with any filing required to be made by a securitizer under the Exchange Act or Regulation AB or (ii) any duty or obligation to undertake any investigation or inquiry related to repurchase activity or otherwise to assume any
additional duties or responsibilities except as expressly set forth in this Section 6.8.

or designees) upon request any and all reports, statements, certifications, records and other information necessary in the good faith determination of the Depositor to permit the Depositor to comply with the provisions of Regulation AB, together

claims, actions and suits, and any and all reasonable costs, expenses and disbursements (including reasonable legal fees and expenses, including legal fees and expenses in connection with the enforcement of their indemnification rights hereunder) of
any kind and nature whatsoever (collectively, “Expenses”) which may at any time be imposed on, incurred by, or asserted against the Owner Trustee or any other Indemnified Party in any way relating to or arising out of this Trust Agreement,
the other Transaction Documents, the Owner Trust Estate, the administration of the Owner Trust Estate or the action or inaction of the Owner Trustee hereunder; provided, however, that the Initial Servicer shall not be liable for or required to
indemnify an Indemnified Party from and against Expenses arising or resulting from any of the matters described in the third sentence of Section 7.1. Except as otherwise provided in Section 5.4(b) of the Indenture, in no event will the
Initial 

  
 25 

 
Servicer or the Owner Trustee be entitled to make any claim upon the Owner Trust Estate for the payment or reimbursement of any Expenses. The indemnities contained in this Section 8.2 shall
survive the resignation or termination of the Owner Trustee or the termination of this Trust Agreement. In the event of any claim, action or proceeding for which indemnity will be sought pursuant to this Section 8.2, the Owner Trustee’s
choice of legal counsel shall be subject to the approval of the Initial Servicer, which approval shall not be unreasonably withheld.

 (a) This Trust Agreement (other than the provisions of Article VIII) shall terminate and be of no
further force or effect and the Trust shall dissolve upon the earlier of (i) the payment to the Servicer, the Noteholders and the Certificateholders of all amounts required to be paid to them pursuant to the terms of the Indenture, the Sale and
Servicing Agreement and this Trust Agreement and (ii) the Distribution Date next succeeding the month which is one year after the maturity or other liquidation of the last Receivable and the disposition of any amounts received upon liquidation
of any property remaining in the Trust. The bankruptcy, liquidation, dissolution, death or incapacity of any Certificateholder shall not operate to terminate this Trust Agreement or the Trust, entitle such Certificateholder’s legal
representatives or heirs to claim an accounting or to take any action or proceeding in any court for a partition or winding up of all or any part of the Trust or Owner Trust Estate or otherwise affect the rights, obligations and liabilities of the
parties hereto. 
 (b) No Certificateholder shall be entitled to revoke or terminate the Trust. 

(c) Notice of any termination of the Trust, specifying the Distribution Date upon which the Certificateholders shall surrender their
Certificates to the Paying Agent for payment of the final distribution and cancellation, shall be given by the Owner Trustee by letter to Certificateholders mailed within five (5) Business Days of receipt of notice of such termination from the
Servicer, stating (i) the Distribution Date upon or with respect to which final payment of the Certificates shall be made upon presentation and surrender of the Certificates at the office of the Paying Agent therein specified, (ii) the
amount of any such final payment and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Certificates at the office of the Paying Agent

Certificateholders concerning surrender of their Certificates and the cost thereof shall be paid out of the funds and other assets that shall remain subject to this Trust Agreement. Subject to applicable escheat laws, any funds remaining in the

and surplus of such corporation or banking association shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Owner Trustee shall cease to be eligible in accordance
with the provisions of this Section 10.1, the Owner Trustee shall resign immediately in the manner and with the effect specified in Section 10.2. 

Section 10.2 Resignation or Removal of Owner Trustee. The Owner Trustee may at any time resign and be discharged from the trusts
hereby created by giving written notice thereof to the Administrator and the Depositor. Upon receiving such notice of resignation, the Administrator shall promptly appoint a successor Owner Trustee (acceptable to the Depositor) by written
instrument, in duplicate, one copy of which instrument shall be delivered to the resigning Owner Trustee and one copy to the successor Owner Trustee. If no successor Owner Trustee shall have been so appointed and have accepted appointment within
thirty (30) days after the giving of such notice of resignation, the resigning Owner Trustee may petition any court of competent jurisdiction for the appointment of a successor Owner Trustee. 

If at any time the Owner Trustee shall cease to be eligible in accordance with the provisions of Section 10.1 and shall fail to resign
after written request therefor by the Administrator, or if at any time the Owner Trustee shall be legally unable to act, or shall be 

  
 27 

 
adjudged bankrupt or insolvent, or a receiver of the Owner Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Owner Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or liquidation, or the Owner Trustee shall otherwise become incapable of acting, then the Administrator shall remove the Owner Trustee. If the Administrator shall remove the Owner
Trustee under the authority of the immediately preceding sentence, the Administrator shall promptly appoint a successor Owner Trustee (acceptable to the Depositor) by written instrument, in duplicate, one copy of which instrument shall be delivered
to the removed Owner Trustee and one copy to the successor Owner Trustee. 
 Any resignation or removal of the Owner Trustee and appointment
of a successor Owner Trustee pursuant to this Section 10.2 shall not become effective until acceptance of appointment by the successor Owner Trustee pursuant to Section 10.3 and payment of all fees and expenses owed to the outgoing Owner
Trustee. The Administrator shall provide notice of such resignation or removal of the Owner Trustee to the Depositor, the Certificateholders, the Indenture Trustee, the Noteholders and the Rating Agencies. 

Section 10.3 Successor Owner Trustee. Any successor Owner Trustee appointed pursuant to Section 10.2 shall execute,
acknowledge and deliver to the Administrator and to its predecessor Owner Trustee an instrument accepting such appointment under this Trust Agreement, and thereupon, subject to the payment of all fees and expenses owed to the predecessor Owner
Trustee, the resignation or removal of the predecessor Owner Trustee shall become effective and such successor Owner Trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations
of its predecessor under this Trust Agreement, with like effect as if originally named as Owner Trustee. The predecessor Owner Trustee shall, upon payment of its fees and expenses, deliver to the successor Owner Trustee all documents, statements and
monies held by it under this Trust Agreement, and the Administrator and the predecessor Owner Trustee shall execute and deliver such instruments and do such other things as may reasonably be required for fully and certainly vesting and confirming in
the successor Owner Trustee all such rights, powers, duties and obligations. 
 No successor Owner Trustee shall accept appointment as
provided in this Section 10.3 unless, at the time of such acceptance, such successor Owner Trustee shall be eligible pursuant to Section 10.1. 

Any successor Owner Trustee appointed pursuant to this Section 10.3 shall file an amendment to the Certificate of Trust with the
Secretary of State reflecting the name and principal place of business of such successor in the State of Delaware. 
 Upon acceptance of
appointment by a successor Owner Trustee pursuant to this Section 10.3, the Administrator shall mail notice of such appointment to all Certificateholders, the Indenture Trustee, the Noteholders and the Rating Agencies. If the Administrator
shall fail to mail such notice within ten (10) days after acceptance of appointment by the successor Owner Trustee, the successor Owner Trustee shall cause such notice to be mailed at the expense of the Administrator.

 Section 10.4 Merger or Consolidation of Owner Trustee. 

(a) If the Owner Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or
assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association, without any further act except the filing of an amendment to the Certificate of Trust, if required under the Statutory
Trust Statute, shall be the successor Owner Trustee; provided, however, that such corporation or banking association must be otherwise qualified and eligible under Section 10.1. The Owner Trustee shall provide the Administrator
(who shall promptly forward to the Rating Agencies) with prior written notice of any such transaction. 
 (b) If at the time such successor
or successors by consolidation, merger or conversion to the Owner Trustee shall succeed to the trusts created by this Trust Agreement any of the Certificates shall have been authenticated but not delivered, any such successor to the Owner Trustee
may adopt the certificate of authentication of any predecessor trustee and deliver such Certificates so authenticated, and in case at that time any of the Certificates shall not have been authenticated, any such successor to the Owner Trustee may
authenticate such Certificates either in the name of any predecessor trustee or in the name of the successor to the Owner Trustee. In all such cases such certificates shall have the full force which the Certificates or this Trust Agreement provide
that the certificate of the Owner Trustee shall have. 
 Section 10.5 Appointment of
Co-Trustee or Separate Trustee. 
 (a) Notwithstanding any other provisions of this Trust
Agreement to the contrary, at any time, for the purpose of meeting any legal requirement of any jurisdiction in which any part of the Owner Trust Estate or any Financed Vehicle may at the time be located, the Administrator and the Owner Trustee
acting jointly shall have the power and may execute and deliver an instrument to appoint one or more Persons approved by the Owner Trustee to act as co-trustee or
co-trustees, jointly with the Owner Trustee, or separate trustee or separate trustees, of all or any part of the Owner Trust Estate, and to vest in such Person or Persons, in such capacity and for the benefit
of the Certificateholders, such title to the Owner Trust Estate, or any part thereof, and, subject to the other provisions of this Section 10.5, such powers, duties, obligations, rights and trusts as the Administrator and the Owner Trustee may
consider necessary or desirable. If the Administrator shall not have joined in such appointment within fifteen (15) days after the receipt by it of a request so to do, the Owner Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee under this Trust Agreement shall be required to meet the terms of eligibility as a successor trustee under Section 10.1 and no notice of the appointment of any co-trustee or separate trustee shall be required under Section 10.3. 
 (b) Each separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions: 

(i) all rights, powers, duties and obligations conferred or imposed upon the Owner Trustee shall be conferred or imposed upon
and exercised or performed by the Owner Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee shall not
be authorized to act separately without the Owner Trustee joining in such act), except to the extent that under any law of any 

  
 29 

 
jurisdiction in which any particular act or acts are to be performed the Owner Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties
and obligations (including the holding of title to the Owner Trust Estate or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but
solely at the direction of the Owner Trustee; 
 (ii) no trustee under this Trust Agreement shall be personally liable by
reason of any act or omission of any other trustee under this Trust Agreement; and 
 (iii) the Administrator and the Owner

Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

Trust Agreement or in the Sale and Servicing Agreement dated as of January 1, 2021 (as amended, supplemented or otherwise modified and in effect from time to time, the “Sale and Servicing Agreement”) among the Trust, the
Depositor, and CarMax Business Services, LLC, as servicer (in such capacity, the “Servicer”). 
 This Certificate is issued
under and is subject to the terms, provisions and conditions of the Trust Agreement, to which Trust Agreement the Holder of this Certificate by virtue of the acceptance hereof assents and by which such Holder is bound. The property of the Trust

 Ex. A-1 

 
by the Obligors pursuant to the Receivables and any other interest of the Seller or the Depositor in such Financed Vehicles; (iv) all proceeds from claims on or refunds of premiums with
respect to physical damage, theft, GAP, credit life or credit disability insurance policies relating to the Financed Vehicles or the Obligors; (v) the Receivable Files; (vi) the Collection Account, the Note Payment Account, the Certificate

other forms of obligations and all other property which at any time constitutes all or part of or is included in the proceeds of any of the foregoing. 

THE RIGHTS OF THE TRUST IN THE FOREGOING PROPERTY OF THE TRUST (OTHER THAN THE CERTIFICATE PAYMENT ACCOUNT AND THE PROCEEDS THEREOF) HAVE BEEN
PLEDGED TO THE INDENTURE TRUSTEE TO SECURE THE PAYMENT OF THE NOTES. 
 Pursuant to the Trust Agreement, there will be distributed on each
Distribution Date to the Person in whose name this Certificate is registered at the close of business on the Business Day preceding such Distribution Date such Certificateholder’s Certificate Percentage Interest in the amount to be distributed
to Certificateholders on such Distribution Date. 
 “Distribution Date” means the 15th day of each month or, if such 15th
day is not a Business Day, the following Business Day, commencing on February 16, 2021. 
 THE HOLDER OF THIS CERTIFICATE ACKNOWLEDGES
AND AGREES THAT ITS RIGHTS TO RECEIVE DISTRIBUTIONS IN RESPECT OF THIS CERTIFICATE ARE SUBORDINATED TO THE RIGHTS OF THE NOTEHOLDERS AS DESCRIBED IN THE TRUST AGREEMENT, THE SALE AND SERVICING AGREEMENT AND THE INDENTURE. 

It is the intent of the Depositor, the Seller, the Servicer and the Certificateholders that, for purposes of federal income taxes, State and
local income taxes and any other income taxes, the Trust will be treated either as a disregarded entity under Treasury Regulation Section 301.7701-3 or as a partnership, and that the Certificateholders
(including the Depositor) will be treated as partners in that partnership. The Certificateholders, by acceptance of a Certificate, agree to such treatment and agree to take no action inconsistent with such treatment. 

  
 Ex. A-2 

 Each Certificateholder, by its acceptance of a Certificate, covenants and agrees that such
Certificateholder will not at any time institute against the Depositor or the Trust, or join in any institution against the Depositor or the Trust of, any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under any
United States federal or State bankruptcy or similar law in connection with any obligations relating to the Notes, the Certificates, the Trust Agreement or any of the other Transaction Documents. 

Distributions on this Certificate will be made as provided in the Trust Agreement by the Paying Agent by wire transfer or check mailed to the
Certificateholder of record in the Certificate Register without the presentation or surrender of this Certificate or the making of any notation hereon. Except as otherwise provided in the Trust Agreement and notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Owner Trustee of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency of the Certificate Registrar maintained for
that purpose in St. Paul, Minnesota. 
 Reference is hereby made to the further provisions of this Certificate set forth on the reverse
hereof, which further provisions shall for all purposes have the same effect as if fully set forth on the face of this Certificate. 
 Unless
the certificate of authentication hereon has been executed by an authorized officer of the Owner Trustee, by manual signature, this Certificate shall not entitle the Holder hereof to any benefit under the Trust Agreement or the Sale and Servicing
Agreement or be valid for any purpose.

 [REVERSE OF CERTIFICATE] 

This Certificate does not represent an obligation of, or an interest in, the Depositor, the Seller, the Servicer, the Administrator, the Owner
Trustee or any Affiliates of any of them, and no recourse may be had against such parties or their assets, except as may be expressly set forth or contemplated herein, in the Trust Agreement or in the other Transaction Documents. In addition, this
Certificate is not guaranteed by any governmental agency or instrumentality and is limited in right of payment to certain collections with respect to the Receivables (and certain other amounts), all as more specifically set forth herein and in the
Sale and Servicing Agreement. 
 The Trust Agreement permits the Depositor and the Owner Trustee, on behalf of the Trust, with certain
exceptions therein provided, to amend or waive from time to time certain terms and conditions set forth in the Trust Agreement without the consent of the Holders of the Certificates. The Trust Agreement also permits the Depositor and the Owner
Trustee, on behalf of the Trust, with certain exceptions as therein provided, to amend or waive certain terms and conditions set forth in the Trust Agreement with the consent of the Holders of the Notes evidencing not less than 51% of the Note
Balance or, if the Notes have been paid in full, the Holders of Certificates evidencing not less than 51% of the aggregate Certificate Percentage Interest. Any such consent or waiver by the Holder of this Certificate shall be conclusive and binding
on such Holder and on all future Holders of this Certificate and of any Certificate issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver is made upon this
Certificate. 
 As provided in the Trust Agreement and subject to certain limitations therein set forth, the Transfer of this Certificate may
be registered in the Certificate Register upon surrender of this Certificate for registration of Transfer at the office or agency of the Certificate Registrar maintained for that purpose in St. Paul, Minnesota and a written instrument of transfer in
form satisfactory to the Certificate Registrar duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates in any authorized denomination and in the same aggregate
principal amount will be issued to the designated transferee or transferees. No service charge shall be made for any registration of Transfer or exchange of Certificates, but the Owner Trustee or the Certificate Registrar may require payment of a
sum sufficient to cover any tax or governmental charge that may be imposed in connection therewith. The initial Certificate Registrar appointed under the Trust Agreement is the Indenture Trustee. 

Each Certificateholder, by its acceptance of a Certificate, shall be deemed to have represented and warranted that such Certificateholder is
not acquiring the Certificate with the assets of any (i) “employee benefit plan” (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) that is subject to Title I of
ERISA, (ii) “plan” described in Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended (the “Code”), including individual retirement accounts and Keogh plans, that is subject to the provisions of
Section 4975 of the Code (iii) entity whose underlying assets include “plan assets” within the meaning of the United States Department of Labor Regulation 29 C.F.R. Section 2510.3-101,
as modified by Section 3(42) of ERISA, by reason of an employee benefit plan’s or plan’s investment in such entity or (iv) employee benefit plan or arrangement not subject to Title

  
 Ex. A-5 

 
I of ERISA or Section 4975 of the Code whose acquisition of a Certificate would constitute or result in a violation of any applicable law that is substantially similar to Title I of ERISA or
Section 4975 of the Code. 
 Any person who is not an affiliate of the Seller and acquires more than 49.9% of the Certificates will be
deemed to represent that it is not a party in interest (within the meaning of ERISA) or a disqualified person (within the meaning of Section 4975(e)(2) of the Code) with respect to any “employee benefit plan” (as defined under
Section 3(3) of ERISA) or any “plan” (as described under Section 4975 of the Code), other than a plan that it sponsors for the benefit of its employees, and that no plan with respect to which it is a party in interest or
disqualified person has or will acquire any interest in the Notes. 
 The Certificates are issuable only in registered form in denominations
as provided in the Trust Agreement, subject to certain limitations therein set forth. 
 The Owner Trustee, the Certificate Registrar and any
Paying Agent may treat the Person in whose name this Certificate is registered in the Certificate Register (as of the day of determination) as the owner of this Certificate for the purpose of receiving distributions pursuant to the Trust Agreement
and for all other purposes whatsoever, and none of the Owner Trustee, the Certificate Registrar or any Paying Agent shall be bound by any notice to the contrary. 

The Trust Agreement, with certain exceptions therein provided, and the Trust shall terminate and be of no further force or effect upon the
earlier of (i) the payment to the Servicer, the Noteholders and the Certificateholders of all amounts required to be paid to them pursuant to the terms of the Indenture, the Sale and Servicing Agreement and the Trust Agreement and (ii) the
Distribution Date next succeeding the month which is one year after the maturity or other liquidation of the last Receivable and the disposition of any amounts received upon liquidation of any property remaining in the Trust. 

THIS CERTIFICATE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE, AND THE OBLIGATIONS, RIGHTS AND
REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

 SECTION 2. REGISTRATION; RESTRICTIONS ON TRANSFER. 

2.1 Restrictions on Transfer. 

(a) Each Holder agrees not to make any disposition of all or any portion of the Shares or Registrable Securities unless and until: 

(i) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition
is made in accordance with such registration statement; or 
 (ii) (A) the transferee has agreed in writing to be bound by the
terms of this Agreement, (B) such Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and (C) if
reasonably requested by the Company, such Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such shares under the Securities Act. It is
agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144, except in unusual circumstances. After its Initial Offering, the Company will not require any transferee pursuant to Rule 144 to be bound by the
terms of this Agreement if the shares so transferred do not remain Registrable Securities hereunder following such transfer. 
 (b)
Notwithstanding the provisions of subsection (a) above, no such restriction shall apply to a transfer by a Holder that is (A) a partnership transferring to its partners or former partners in accordance with partnership interests,
(B) a corporation transferring to a wholly-owned subsidiary or a parent corporation that owns all of the capital stock of the Holder, (C) a limited liability company transferring to its members or former members in accordance with their
interest in the limited liability company, or (D) an individual transferring to an Affiliate of such Holder, or to Holder’s family member or trust for the benefit of an individual Holder; provided that in each case the transferee
will agree in writing to be subject to the terms of this Agreement to the same extent as if he were an original Holder hereunder. 

(c) Each certificate representing Shares or Registrable Securities shall be stamped or otherwise imprinted with legends substantially
similar to the following (in addition to any legend required under applicable state securities laws): 
 THE SECURITIES REPRESENTED HEREBY
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR UNLESS SUCH SALE,
PLEDGE, HYPOTHECATION OR TRANSFER IS MADE IN COMPLIANCE WITH RULE 144 OF THE ACT OR THE COMPANY, UPON ITS REASONABLE REQUEST, HAS RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED. 

  
 4 

 THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS
CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN AMENDED AND RESTATED INVESTOR RIGHTS AGREEMENT BY AND BETWEEN THE STOCKHOLDER AND THE COMPANY. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE
COMPANY. 
 (d) The Company shall be obligated to promptly reissue unlegended certificates at the request of any Holder thereof if the
Company has completed its Initial Offering and the Holder shall have obtained an opinion of counsel (which counsel may be counsel to the Company) reasonably acceptable to the Company to the effect that the securities proposed to be disposed of may
lawfully be so disposed of without registration, qualification and legend; provided, that the second legend listed above shall be removed only at such time as the Holder of such certificate is no longer subject to any restrictions hereunder.

 (e) Any legend endorsed on an instrument pursuant to applicable state securities laws and the stop-transfer instructions with
respect to such securities shall be removed upon receipt by the Company of an order of the appropriate blue sky authority authorizing such removal. 

2.2 Demand Registration. 

(a) Subject to the conditions of this Section 2.2, if the Company shall receive a written request from the Holders of at least
seventy-five percent (75%) of the Registrable Securities (the “Initiating Holders”) that the Company file a registration statement under the Securities Act covering the registration of at least a majority of the Registrable
Securities then outstanding (or a lesser percent if the anticipated aggregate offering price, net of underwriting discounts and commissions, would exceed $10,000,000), then the Company shall, within thirty (30) days of the receipt
thereof, give written notice of such request to all Holders, and subject to the limitations of this Section 2.2, effect, as expeditiously as reasonably possible, the registration under the Securities Act of all Registrable Securities that all
Holders request to be registered. 
 (b) If the Initiating Holders intend to distribute the Registrable Securities covered by their
request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Section 2.2(a) or any request pursuant to Section 2.4 and the Company shall include such information in the written notice
referred to in Section 2.2(a) or Section 2.4(a), as applicable. In such event, the right of any Holder to include its Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such
underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement
in customary form with the underwriter or underwriters selected for such underwriting by the Holders of a majority of the Registrable Securities held by all Initiating Holders (which underwriter or underwriters shall be reasonably acceptable to the
Company). Notwithstanding any other provision of this Section 2.2 or Section 2.4, if the underwriter advises the Company that marketing factors require a limitation of 

  
 5 

 
the number of securities to be underwritten (including Registrable Securities) then the Company shall so advise all Holders of Registrable Securities that would otherwise be underwritten pursuant
hereto, and the number of shares that may be included in the underwriting shall be allocated to the Holders of such Registrable Securities on a pro rata basis based on the number of Registrable Securities held by all such Holders (including
the Initiating Holders). Any Registrable Securities excluded or withdrawn from such underwriting shall be withdrawn from the registration. 

(c) The Company shall not be required to effect a registration pursuant to this Section 2.2: 

(i) prior to the second anniversary of the date of this Agreement; 

(ii) after the Company has effected one (1) registration pursuant to this Section 2.2, and such registration has been
declared or ordered effective; 
 (iii) during the period starting with the date of filing of, and ending on the date one hundred
eighty (180) days following the effective date of the registration statement pertaining to a public offering, other than pursuant to a Special Registration Statement; provided that the Company makes reasonable good faith efforts to cause
such registration statement to become effective; 
 (iv) if within thirty (30) days of receipt of a written request from
Initiating Holders pursuant to Section 2.2(a), the Company gives notice to the Holders of the Company’s intention to file a registration statement for a public offering, other than pursuant to a Special Registration Statement,
within ninety (90) days; 
 (v) if the Company shall furnish to Holders requesting a registration statement pursuant to this
Section 2.2 a certificate signed by the Chairman of the Board stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such registration
statement to be effected at such time, in which event the Company shall have the right to defer such filing for a period of not more than one hundred twenty (120) days after receipt of the request of the Initiating Holders; provided that
such right to delay a request shall be exercised by the Company not more than twice in any twelve (12) month period; 
 (vi) if
the Initiating Holders propose to dispose of shares of Registrable Securities that may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 2.4 below; or 

(vii) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent
to service of process in effecting such registration, qualification or compliance. 
 2.3 Piggyback Registrations. The Company
shall notify all Holders of Registrable Securities in writing at least fifteen (15) days prior to the filing of any registration statement under the Securities Act for purposes of a public offering of securities of the Company
(including, but not limited to, registration statements relating to secondary offerings of securities of the Company, but excluding Special Registration Statements) and will afford each such Holder an opportunity to

  
 6 

 
include in such registration statement all or part of such Registrable Securities held by such Holder. Each Holder desiring to include in any such registration statement all or any part of the
Registrable Securities held by it shall, within fifteen (15) days after the above-described notice from the Company, so notify the Company in writing. Such notice shall state the intended method of disposition of the Registrable Securities by
such Holder. If a Holder decides not to include all of its Registrable Securities in any registration statement thereafter filed by the Company, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any
subsequent registration statement or registration statements as may be filed by the Company with respect to offerings of its securities, all upon the terms and conditions set forth herein. 

(a) Underwriting. If the registration statement of which the Company gives notice under this Section 2.3 is for an
underwritten offering, the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to include Registrable Securities in a registration pursuant to this Section 2.3 shall be conditioned upon
such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Securities through such
underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. Notwithstanding any other provision of this Agreement, if the Company determines in good
faith, based on consultation with the underwriter, that marketing factors require a limitation of the number of shares to be underwritten, the number of shares that may be included in the underwriting shall be allocated, first, to the Company;
second, to the Holders on a pro rata basis based on the total number of Registrable Securities held by the Holders; and third, to any stockholder of the Company (other than a Holder) on a pro rata basis; provided, however, that
no such reduction shall reduce the amount of securities of the selling Holders included in the registration below twenty five percent (25%) of the total amount of securities included in such registration, unless such offering is the Initial Offering
and such registration does not include shares of any other selling stockholders, in which event any or all of the Registrable Securities of the Holders may be excluded in accordance with the immediately preceding clause. If any Holder disapproves of
the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter, delivered at least ten (10) business days prior to the effective date of the registration statement. Any
Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration. For any Holder which is a partnership, limited liability company or corporation, the partners, retired partners, members,
retired members and stockholders of such Holder, or the estates and family members of any such partners, retired partners, members and retired members and any trusts for the benefit of any of the foregoing person shall be deemed to be a single
“Holder,” and any pro rata reduction with respect to such “Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Holder,”
as defined in this sentence. 
 (b) Right to Terminate Registration. The Company shall have the right to terminate or withdraw
any registration initiated by it under this Section 2.3 whether or not any Holder has elected to include securities in such registration. The Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with
Section 2.5 hereof. 

  
 7 

 2.4 Form S-3 Registration. In case the
Company shall receive from any Holder or Holders of at least thirty percent (30%) of the Registrable Securities a written request or requests that the Company effect a registration on Form S-3 (or any
successor to Form S-3) or any similar short-form registration statement and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or
Holders, the Company will: 
 (a) promptly give written notice of the proposed registration, and any related qualification or
compliance, to all other Holders of Registrable Securities; and 
 (b) as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company; provided,
however, that the Company shall not be obligated to effect any such registration, qualification or compliance pursuant to this Section 2.4: 

(i) if Form S-3 is not available for such offering by the Holders, or 

(ii) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration,
propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than five million dollars ($5,000,000), or 

(iii) if within thirty (30) days of receipt of a written request from any Holder or Holders pursuant to this Section 2.4, the
Company gives notice to such Holder or Holders of the Company’s intention to make a public offering within ninety (90) days, other than pursuant to a Special Registration Statement, or 

(iv) if the Company shall furnish to the Holders a certificate signed by the Chairman of the Board of Directors of the Company stating
that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such Form S-3 registration to be effected at such time,
in which event the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than one hundred twenty (120) days after receipt of the request of
the Holder or Holders under this Section 2.4; provided, that such right to delay a request shall be exercised by the Company not more than twice in any twelve (12) month period, or 

(v) if the Company has already effected two (2) registrations on
Form S-3 for the Holders pursuant to this Section 2.4, or 
 (vi) in any particular
jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance. 

  
 8 

 (c) Subject to the foregoing, the Company shall file a
Form S-3 registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the requests of the Holders. Registrations
effected pursuant to this Section 2.4 shall not be counted as demands for registration or registrations effected pursuant to Section 2.2. All Registration Expenses incurred in connection with registrations requested pursuant to this
Section 2.4 after the first two (2) registrations shall be paid by the selling Holders pro rata in proportion to the number of shares to be sold by each such Holder in any such registration. 

2.5 Expenses of Registration. Except as specifically provided herein, all Registration Expenses incurred in connection with any
registration, qualification or compliance pursuant to Section 2.2, 2.3 or 2.4 herein shall be borne by the Company. All Selling Expenses incurred in connection with any registrations hereunder, shall be borne by the holders of the securities so
registered pro rata on the basis of the number of shares so registered. The Company shall not, however, be required to pay for expenses of any registration proceeding begun pursuant to Section 2.2 or 2.4, the request of which has been
subsequently withdrawn by the Initiating Holders unless (a) the withdrawal is based upon material adverse information concerning the Company of which the Initiating Holders were not aware at the time of such request or (b) the Holders of a
majority of Registrable Securities agree to deem such registration to have been effected as of the date of such withdrawal for purposes of determining whether the Company shall be obligated pursuant to Section 2.2(c) or 2.4(b)(v), as
applicable, to undertake any subsequent registration, in which event such right shall be forfeited by all Holders. If the Holders are required to pay the Registration Expenses, such expenses shall be borne by the holders of securities (including
Registrable Securities) requesting such registration in proportion to the number of shares for which registration was requested. If the Company is required to pay the Registration Expenses of a withdrawn offering pursuant to clause (a) above,
then such registration shall not be deemed to have been effected for purposes of determining whether the Company shall be obligated pursuant to Section 2.2(c) or 2.4(b)(v), as applicable, to undertake any subsequent registration. 

2.6 Obligations of the Company. Whenever required to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible: 
 (a) Prepare and file with the SEC a registration statement with respect to such Registrable
Securities and use all reasonable efforts to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective
for up to thirty (30) days or, if earlier, until the Holder or Holders have completed the distribution related thereto; provided, however, that at any time, upon written notice to the participating Holders and for a period not to exceed ninety
(90) days thereafter (the “Suspension Period”), the Company may delay the filing or effectiveness of any registration statement or suspend the use or effectiveness of any registration statement (and the Initiating
Holders hereby agree not to offer or sell any Registrable Securities pursuant to such registration statement during the Suspension Period) if the Company reasonably believes that there is or may be in existence material nonpublic information or
events involving the Company, the failure of which to be disclosed in the prospectus included in the registration statement could result in a Violation (as defined below) and that (i) would be required to be made in any registration statement
filed with the SEC by the Company so that such registration statement would not be materially misleading; (ii) would not be required to be made at such time but for the filing, effectiveness or continued use of such registration statement and
(iii) the Company has a bona fide business purpose for not disclosing publicly. In the event that the Company shall exercise its right 

  
 9 

 
to delay or suspend the filing or effectiveness of a registration hereunder, the applicable time period during which the registration statement is to remain effective shall be extended by a
period of time equal to the duration of the Suspension Period. The Company may extend the Suspension Period for an additional consecutive sixty (60) days with the consent of the holders of a majority of the Registrable Securities
registered under the applicable registration statement, which consent shall not be unreasonably withheld. No more than two (2) such Suspension Periods shall occur in any twelve (12) month period. If so directed by the Company, all Holders
registering shares under such registration statement shall (i) not offer to sell any Registrable Securities pursuant to the registration statement during the period in which the delay or suspension is in effect after receiving notice of such
delay or suspension; and (ii) use their best efforts to deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such Holders’ possession, of the prospectus relating to such Registrable
Securities current at the time of receipt of such notice. Notwithstanding the foregoing, the Company shall not be required to file, cause to become effective or maintain the effectiveness of any registration statement other than a registration
statement on Form S-3 that contemplates a distribution of securities on a delayed or continuous basis pursuant to Rule 415 under the Securities Act. 

(b) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the period set forth in subsection (a) above.

 (c) Furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them. 

(d) Use its reasonable efforts to register and qualify the securities covered by such registration statement under such other securities
or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent
to service of process in any such states or jurisdictions. 
 (e) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter(s) of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an
agreement. 
 (f) Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus
relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. The Company will use reasonable efforts to amend or supplement such prospectus
in order to cause such prospectus not to include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then
existing. 

  
 10 

 (g) Use its reasonable efforts to furnish, on the date that such Registrable
Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters, (i) an opinion, dated as of such date, of the counsel representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and (ii) a letter, dated as of such date, from the independent certified public accountants of the Company, in form and
substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering addressed to the underwriters. 

2.7 Delay of Registration; Furnishing Information. 

(a) No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result
of any controversy that might arise with respect to the interpretation or implementation of this Section 2. 
 (b) It shall be a
condition precedent to the obligations of the Company to take any action pursuant to Section 2.2, 2.3 or 2.4 that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them
and the intended method of disposition of such securities as shall be required to effect the registration of their Registrable Securities. 

(c) The Company shall have no obligation with respect to any registration requested pursuant to Section 2.2 or Section 2.4 if
the number of shares or the anticipated aggregate offering price of the Registrable Securities to be included in the registration does not equal or exceed the number of shares or the anticipated aggregate offering price required to originally
trigger the Company’s obligation to initiate such registration as specified in Section 2.2 or Section 2.4, whichever is applicable. 

2.8 Indemnification. In the event any Registrable Securities are included in a registration statement under Sections 2.2,
2.3 or 2.4: 
 (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, members,
officers and directors of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any
losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”) by the Company: (i) any untrue statement or alleged untrue statement of a material fact
contained in such registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state
therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company 

  
 11 

 
of the Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law in connection with
the offering covered by such registration statement; and the Company will reimburse each such Holder, partner, member, officer, director, underwriter or controlling person for any legal or other expenses reasonably incurred by them in connection
with investigating or defending any such loss, claim, damage, liability or action; provided however, that the indemnity agreement contained in this Section 2.8(a) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action
to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder, partner, member, officer,
director, underwriter or controlling person of such Holder. 
 (b) To the extent permitted by law, each Holder will, if Registrable
Securities held by such Holder are included in the securities as to which such registration qualifications or compliance is being effected, indemnify and hold harmless the Company, each of its directors, its officers and each person, if any, who
controls the Company within the meaning of the Securities Act, any underwriter and any other Holder selling securities under such registration statement or any of such other Holder’s partners, directors or officers or any person who controls
such Holder, against any losses, claims, damages or liabilities (joint or several) to which the Company or any such director, officer, controlling person, underwriter or other such Holder, or partner, director, officer or controlling person of such
other Holder may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any of the following
statements: (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Securities Act (collectively, a “Holder Violation”), in each case to the extent (and only to the extent) that such Holder Violation occurs in reliance upon and in conformity with written
information furnished by such Holder under an instrument duly executed by such Holder and stated to be specifically for use in connection with such registration; and each such Holder will reimburse any legal or other expenses reasonably incurred by
the Company or any such director, officer, controlling person, underwriter or other Holder, or partner, officer, director or controlling person of such other Holder in connection with investigating or defending any such loss, claim, damage,
liability or action if it is judicially determined that there was such a Holder Violation; provided, however, that the indemnity agreement contained in this Section 2.8(b) shall not apply to amounts paid in settlement of any such loss,
claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided further, that in no event shall any indemnity under this Section 2.8 exceed
the net proceeds from the offering received by such Holder. 

  
 12 

 (c) Promptly after receipt by an indemnified party under this Section 2.8 of
notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.8, deliver to the indemnifying party a
written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense
thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses thereof to be paid by the indemnifying party, if representation
of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The
failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.8 to the extent,
and only to the extent, prejudicial to its ability to defend such action, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under
this Section 2.8. 
 (d) If the indemnification provided for in this Section 2.8 is held by a court of competent
jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by
applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and
of the indemnified party on the other in connection with the Violation(s) or Holder Violation(s) that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying
party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied
by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, that in no event shall any
contribution by a Holder hereunder exceed the net proceeds from the offering received by such Holder. 
 (e) The obligations of the
Company and Holders under this Section 2.8 shall survive completion of any offering of Registrable Securities in a registration statement and, with respect to liability arising from an offering to which this Section 2.8 would apply that is
covered by a registration filed before termination of this Agreement, such termination. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment
or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. 

2.9 Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this
Section 2 may be assigned by a Holder to a transferee or assignee of Registrable Securities (for so long as such shares remain Registrable Securities) that (a) is a partner, retired partner or affiliated fund of a Holder that is a
partnership, (b) is a member or former member of a Holder that is a limited liability company, (c) is an Affiliate of Holder or a Holder’s family member or trust for the benefit of an individual Holder, or (d) holds at least
1,000,000 Shares (a “Major Investor”); provided, however, (i) the transferor shall, within ten (10) 

  
 13 

 
days after such transfer, furnish to the Company written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being
assigned and (ii) such transferee shall agree to be subject to all restrictions set forth in this Agreement. 
 2.10
Limitation on Subsequent Registration Rights. Other than as provided in Section 6.10, after the date of this Agreement, the Company shall not enter into any agreement with any holder or prospective holder of any securities of the Company
that would grant such holder rights to demand the registration of shares of the Company’s capital stock, or to include such shares in a registration statement that would reduce the number of shares includable by the Holders. 

2.11 “Market Stand-Off” Agreement. Each Holder hereby
agrees that such Holder shall not sell, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Common Stock (or other securities) of the
Company held by such Holder immediately before the effective date of the registration statement for the applicable offering during the 180-day period following the effective date of the Initial Offering (or
such longer period, as the underwriters or the Company shall request in order to facilitate compliance with FINRA Rule 2241 or any successor or similar rule or regulation); provided, that, with respect to the above, all officers and directors of the
Company and holders of at least one percent (1%) of the Company’s voting securities, voting as a single class on an as-if converted to Common Stock (as defined in the Certificate) basis, are bound by and
have entered into similar agreements. The obligations described in this Section 2.11 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the
future. Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply pro rata to all Holders subject to such agreements, based on the number of shares subject to such
agreements. 
 2.12 Agreement to Furnish Information. Each Holder agrees to execute and deliver such other agreements as may be
reasonably requested by the Company or the managing underwriters that are consistent with the Holder’s obligations under Section 2.11 or that are necessary to give further effect thereto. In addition, if requested by the Company or the
representative of the underwriters of Common Stock (or other securities) of the Company, each Holder shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection
with the completion of any public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in Section 2.11 and this Section 2.12 shall not apply to a Special
Registration Statement. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said day period. Each Holder agrees that any transferee
of any shares of Registrable Securities shall be bound by Sections 2.11 and 2.12. The underwriters of the Company’s stock are intended third party beneficiaries of Sections 2.11 and 2.12 and shall have the right, power and authority to
enforce the provisions hereof as though they were a party hereto. 

  
 14 

 2.13 Rule 144 Reporting. With a view to making available to the Holders the
benefits of certain rules and regulations of the SEC which may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its best efforts to: 

(a) Make and keep public information available, as those terms are understood and defined in SEC Rule 144 or any similar or
analogous rule promulgated under the Securities Act, at all times after the effective date of the first registration filed by the Company for an offering of its securities to the general public; 

(b) File with the SEC, in a timely manner, all reports and other documents required of the Company under the Exchange Act; and 

(c) So long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request: a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144 of the Securities Act, and of the Exchange Act (at any time after it has become subject to such reporting requirements); a copy of the most recent annual or quarterly
report of the Company filed with the SEC; and such other reports and documents as a Holder may reasonably request in connection with availing itself of any rule or regulation of the SEC allowing it to sell any such securities without registration.

 2.14 Maintained Shelf Registration. In connection with its Initial Offering, the Company shall agree to enter into an
agreement with any Holder who may be deemed an “Affiliate” as defined under Rule 405 of the Securities Act of 1933, to provide for a maintained selling shareholder shelf registration. 

2.15 Termination of Registration Rights. The right of any Holder to request registration or inclusion of Registrable Securities
in any registration pursuant to Section 2.2, Section 2.3, or Section 2.4 hereof shall terminate upon the earlier of: (i) upon a deemed “Liquidation Event” as defined in the Certificate; or (ii) such
time as the Company has completed its Initial Offering and all Registrable Securities of the Company issuable or issued upon conversion of the Shares held by and issuable to such Holder (and its affiliates) may be sold pursuant to Rule 144 without
restrictions on volume of shares sold and frequency of sales or compliance with Rule 144(c)(1) during any ninety (90) day period. Upon such termination, such shares shall cease to be “Registrable Securities” hereunder for all
purposes. 
 SECTION 3. COVENANTS OF THE COMPANY. 

3.1 Basic Financial Information and Reporting. 

(a) The Company will maintain true books and records of account in which full and correct entries will be made of all its business
transactions pursuant to a system of accounting established and administered in accordance with generally accepted accounting principles consistently applied (except as noted therein or as disclosed to the recipients thereof), and will set aside on
its books all such proper accruals and reserves as shall be required under generally accepted accounting principles consistently applied. 

  
 15 

 (b) To the extent requested by a Major Investor: 

(i) As soon as practicable after the end of each fiscal year of the Company, and in any event within one hundred twenty
(120) days thereafter, the Company will furnish such Investor a balance sheet of the Company, as at the end of such fiscal year, and a statement of income and a statement of cash flows of the Company, for such year, setting forth in each
case in comparative form the figures for the previous fiscal year, all in reasonable detail, all such financial statements audited and certified by independent public accountants of nationally recognized standing selected by the Company; 

(ii) The Company will furnish such Major Investor, as soon as practicable after the end of the first, second and third quarterly
accounting periods in each fiscal year of the Company, and in any event within forty-five (45) days thereafter, a balance sheet of the Company as of the end of each such quarterly period, and a statement of income and a statement
of cash flows of the Company for such period and for the current fiscal year to date; each of which will be unaudited and prepared in good faith by the management of the Company; and 

(iii) The Company will furnish each such Major Investor at least thirty (30) days prior to the beginning of each fiscal year an
annual budget and operating plans for such fiscal year (and as soon as available, any subsequent written revisions thereto). 
 3.2
Inspection Rights. Each Major Investor shall have the right to visit and inspect any of the properties of the Company or any of its subsidiaries, and to discuss the affairs, finances and accounts of the Company or any of its subsidiaries with
its officers, and to review such information as is reasonably requested all at such reasonable times and as often as may be reasonably requested; provided, however, that the Company shall not be obligated under this Section 3.2 with
respect to a competitor of the Company or with respect to information which the Board of Directors determines in good faith is confidential or attorney-client privileged and should not, therefore, be disclosed. 

3.3 Confidentiality of Records. Each Investor agrees to use the same degree of care as such Investor uses to protect its own
confidential information to keep confidential any information furnished to such Investor pursuant to Section 3.1 and 3.2 hereof that the Company identifies as being confidential or proprietary (so long as such information is not in the public
domain), except that such Investor may disclose such proprietary or confidential information (i) to any partner, subsidiary or parent of such Investor as long as such partner, subsidiary or parent is advised of and agrees or has agreed to be
bound by the confidentiality provisions of this Section 3.3 or comparable restrictions; (ii) at such time as it enters the public domain through no fault of such Investor; (iii) that is communicated to it free of any obligation of
confidentiality; (iv) that is developed by Investor or its agents independently of and without reference to any confidential information communicated by the Company; or (v) as required by applicable law. 

3.4 Reservation of Common Stock. The Company will at all times reserve and keep available, solely for issuance and delivery upon
the conversion of the Shares, all Common Stock issuable from time to time upon such conversion. 

  
 16 

 3.5 Proprietary Information and Inventions Agreement. The Company shall
require all employees and consultants to execute and deliver a Proprietary Information and Inventions Agreement substantially in a form approved by the Company’s counsel or Board of Directors. 

3.6 Directors’ Liability and Indemnification. The Certificate and bylaws of the Company shall provide
(a) for elimination of the liability of director to the maximum extent permitted by law and (b) for indemnification of directors for acts on behalf of the Company to the maximum extent permitted by law. 

3.7 Termination of Covenants. All covenants of the Company contained in Section 3 of this Agreement shall expire and
terminate as to each Investor upon the earlier of (i) the effective date of the registration statement pertaining to an Initial Offering, (ii) winding up of the Company, or (iii) an “Acquisition” as defined in
the Certificate . 
 SECTION 4. RIGHTS OF FIRST REFUSAL. 

4.1 Subsequent Offerings. Subject to applicable securities laws, each Major Investor shall have a right of first refusal to
purchase its pro rata share of all Equity Securities, as defined below, that the Company may, from time to time, propose to sell and issue after the date of this Agreement, other than the Equity Securities excluded by Section 4.7 hereof;
provided, however, that each Major Investor may elect to receive some or all of its pro rata share of the Equity Securities in shares of a non-voting series thereof. Each Major
Investor’s pro rata share is equal to the ratio of (a) the number of shares of the Company’s Common Stock (including all shares of Common Stock issuable or issued upon conversion of the Shares or upon the exercise of
outstanding warrants or options) of which such Major Investor is deemed to be a holder immediately prior to the issuance of such Equity Securities to (b) the total number of shares of the Company’s outstanding Common Stock (including all
shares of Common Stock issued or issuable upon conversion of the Shares or upon the exercise of any outstanding warrants or options that are in the money) immediately prior to the issuance of the Equity Securities. The term “Equity
Securities” shall mean (i) any Common Stock, preferred stock of the Company or other security of the Company, (ii) any security convertible into or exercisable or exchangeable for, with or without consideration, any Common
Stock, preferred stock of the Company or other security (including any option to purchase such a convertible security), (iii) any security carrying any warrant or right to subscribe to or purchase any Common Stock, preferred stock of the
Company or other security or (iv) any such warrant or right. 
 4.2 Exercise of Rights. If the Company proposes to issue
any Equity Securities, it shall give each Major Investor written notice of its intention, describing the Equity Securities, the price and the terms and conditions upon which the Company proposes to issue the same. Each Major Investor shall have
fifteen (15) days from the giving of such notice to agree to purchase its pro rata share of the Equity Securities for the price and upon the terms and conditions specified in the notice by giving written notice to the Company and
stating therein the quantity of Equity Securities to be purchased. Notwithstanding the foregoing, the Company shall not be required to offer or sell such Equity Securities to any Major Investor who would cause the Company to be in violation of
applicable federal securities laws by virtue of such offer or sale. 

  
 17 

 4.3 Issuance of Equity Securities to Other Persons. If not all of the Major
Investors elect to purchase their pro rata share of the Equity Securities, then the Company shall promptly notify in writing the Major Investors who do so elect and shall offer such Major Investors the right to acquire such unsubscribed
shares and, to the extent such Major Investors apply to purchase more than the amount of undersubscribed shares, such Major Investors shall be offered the right to acquire such unsubscribed shares on a pro rata basis based on the amount of
Equity Securities that such Major Investors’ own immediately prior to the proposed issuance. The Major Investors shall have five (5) days after receipt of such notice to notify the Company of its election to purchase all or a portion
thereof of the unsubscribed shares. The Company shall have ninety (90) days thereafter to sell the Equity Securities in respect of which the Major Investor’s rights were not exercised, at a price and upon general terms and
conditions not materially more favorable to the purchasers thereof than specified in the Company’s notice to the Major Investors pursuant to Section 4.2 hereof. If the Company has not sold such Equity Securities within ninety
(90) days of the notice provided pursuant to Section 4.2, the Company shall not thereafter issue or sell any Equity Securities, without first offering such securities to the Major Investors in the manner provided above. 

4.4 Sale Without Notice. In lieu of giving notice to the Major Investors prior to the issuance of Equity Securities as provided
in Section 4.2, the Company may elect to give notice to the Major Investors within thirty (30) days after the issuance of Equity Securities. Such notice shall describe the type, price and terms of the Equity Securities. Each Major Investor
shall have twenty (20) days from the date of receipt of such notice to elect to purchase up to the number of shares that would, if purchased by such Major Investor, maintain such Major Investor’s pro rata share (as set forth in
Section 4.1) of the Company’s equity securities. The closing of such sale shall occur within sixty (60) days of the date of notice to the Major Investors. 

4.5 Termination and Waiver of Rights of First Refusal. The rights of first refusal established by this Section 4 shall not
apply to, and shall terminate upon the earlier of (i) the effective date of the registration statement pertaining to the Company’s Initial Offering or (ii) an Acquisition. Notwithstanding Section 6.5 hereof, the rights of first
refusal established by this Section 4 may be amended, or any provision waived with and only with the written consent of the Company and the Major Investors holding a majority of the Registrable Securities held by all Major
Investors, or as permitted by Section 6.5. 
 4.6 Assignment of Rights of First Refusal. The rights of first refusal of
each Investor under this Section 4 may be assigned to the same parties, subject to the same restrictions as any transfer of registration rights pursuant to Section 2.9. 

4.7 Excluded Securities. The rights of first refusal established by this Section 4 shall have no application to any of the
following Equity Securities: 
 (a) Any Equity Securities excluded from the definition of “Additional Shares of Common
Stock” in Article IV (D)(3)(h)(v) of the Certificate, as amended from time. 
 (b) any Equity Securities issued in connection
with any stock split, stock dividend or recapitalization by the Company; 
 (c) any Equity Securities that are issued by the Company
pursuant to a registration statement filed under the Securities Act; and 

  
 18 

 (d) any Equity Securities issued by the Company in an Additional Closing (as defined
in the Purchase Agreement). 
 SECTION 5. IPO SHARES 

5.1 Upon the closing of the Initial Offering, each of the Directed Purchasers may elect to purchase (each, a “Directed
Purchaser Option”), in which case the Company shall sell and issue to the Directed Purchaser, the IPO Shares. The IPO Shares will be sold by the Company and purchased by each Directed Purchaser at a purchase price per share equal the
IPO Price. The IPO Shares shall, subject to the determination by the Company, with the advice of counsel, that such offer and/or sale does not violate applicable law, be registered by the Company for sale by the underwriters to the Directed
Purchasers pursuant to the registration statement filed under the Securities Act in connection with the Initial Offering. Should either the Company not be permitted to offer to the Directed Purchasers all of the IPO Shares as an allotment in the
Initial Offering, or the Directed Purchasers not be able to purchase all of the IPO Shares as an allotment in the Initial Offering, in either case as a result of the applicable law, then, at each Directed Purchaser’s option, such Directed
Purchaser shall instead purchase from the Company, and the Company shall sell to each such Directed Purchaser in a private placement (the “Private Placement”), concurrently with the Initial Offering, the portion of the IPO
Shares that is not included as an allotment in the Initial Offering at the IPO Price, with the result that the IPO Shares purchased in the Initial Offering and the IPO Shares purchased in the Private Placement shall, in the aggregate, equal the
Maximum IPO Purchaser IPO Shares. 
 5.2 Notwithstanding the foregoing, the foregoing obligations of the Company to sell IPO Shares in
connection with the Directed Purchaser Option shall terminate on the earlier of (i) the closing of a deemed Liquidation Event; and (ii) the consummation of a Qualified Public Offering (as defined in the Certificate) and satisfaction of the
obligations of the Company set forth in Section 5 of this Agreement. 
 5.3 At least ten (10) business days prior to the
closing of the Initial Offering, the Company will provide written notice of such closing to each Directed Purchaser (each, an “IPO Notice”), which such IPO Notice will (i) include estimates of the IPO Price and the
Maximum Purchaser IPO Shares and (ii) specify the estimated number of shares available for sale in the Initial Offering and, if applicable, the estimated number of shares available for sale in the Private Placement. Prior to the sixth (6th)
business day after receipt of an IPO Notice, each Directed Purchaser shall provide written notice to the Company (each, a “Purchaser Election Notice”) of whether such Directed Purchaser elects to exercise its Purchaser Option
and, if so, the number of shares of Common Stock that will constitute the IPO Shares, up to the Maximum Purchaser IPO Shares. If the Purchaser does not deliver the Purchaser Election Notice prior to the sixth (6th) business day after its receipt of
the IPO Notice, the IPO Shares will equal zero. Promptly following the determination of the IPO Price, the Company shall notify each Directed Purchaser of the IPO Price and the number of IPO Shares, determined in accordance with this
Section 5.3. The purchase and sale of the IPO Shares (both in the Initial Offering and, if applicable, the Private Placement) shall take place on the day of such closing of the Initial Offering, at such time and place as the Company and the
Directed Purchasers mutually agree upon orally or in writing (which time and place are hereby designated as the “IPO Closing”). At the IPO Closing, the Company shall deliver to each Directed Purchaser a certificate
representing the IPO Shares against payment of the purchase price therefor by wire transfer. 

  
 19 

 5.4 Notwithstanding the foregoing, in the event that any authorization, approval or
permit of any governmental authority or regulatory body of the United States or of any other applicable jurisdiction is required in connection with the issuance of the IPO Shares at the IPO Closing, then the Company and the Directed Purchasers
hereto shall use commercially reasonable efforts to promptly obtain such authorizations, approvals and permits, and the IPO Closing shall take place within three (3) business days after all such authorizations, approvals and permits have been
obtained. 
 SECTION 6. MISCELLANEOUS. 

6.1 Governing Law. This Agreement shall be governed by and construed under the laws of the State of Delaware in all

consent, or approval of any kind or character on any party’s part of any breach, default or noncompliance under the Agreement or any waiver on such party’s part of any provisions or conditions of this Agreement must be in writing and shall

limitation, all fees, costs and expenses of appeals. 
 6.9 Titles and Subtitles. The titles of the sections and subsections of
this Agreement are for convenience of reference only and are not to be considered in construing this Agreement. 
 6.10 Additional
