Item 6.          Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Registration Rights

5AM VI, 5AM Opportunities and certain other holders of shares of the Issuer’s Common Stock entered into an amended and restated investors’ rights agreement dated as of June 30, 2020, or the investors’ rights agreement. The registration rights provisions of this agreement provide those holders with demand, piggyback and Form S-3 registration rights with respect to the shares of Common Stock held by them. An aggregate of 24,924,501 shares of Common Stock are entitled to these registration rights. These shares are collectively referred to herein as registrable securities.

Demand Registration Rights

At any time beginning 180 days following February 4, 2021 (the effective date of the Issuer’s registration statement with respect to the IPO), the holders of a majority of registrable securities then outstanding have the right to demand that the Issuer file a registration statement covering at least 40% of the registrable securities then outstanding (or a lesser percent if the aggregate offering price exceeds $15.0 million net of certain selling expenses). The Issuer is obligated to effect at most two registrations in response to these demand registration rights. These demand registration rights are subject to specified conditions and limitations, including the right of the underwriters, if any, to limit the number of shares included in any such registration under specified circumstances. Upon such a request, the Issuer is required to effect the registration as soon as practicable, but in any event no later than 60 days after the receipt of such request.

Piggyback Registration Rights

If the Issuer proposes to register any of its securities under the Securities Act either for its own account or for the account of other stockholders, the holders of registrable securities will each be entitled to notice of the registration and will be entitled to include their shares of Common Stock in the registration statement. These piggyback registration rights are subject to specified conditions and limitations, including the right of the underwriters to limit the number of shares included in any such registration under specified circumstances, and do not apply to a registration relating to any equity incentive plan, stock purchase or similar plan, a transaction under Rule 145 of the Securities Act, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the registrable securities or a registration related to Common Stock issued upon conversion of debt securities.

Registration on Form S-3

At any time after the Issuer becomes eligible to file a registration statement on Form S-3, the holders of at least 15% of the registrable securities then outstanding will be entitled to request to have such shares registered by the Issuer on a Form S-3 registration statement. These Form S-3 registration rights are subject to other specified conditions and limitations, including the condition that the anticipated aggregate offering price, net of certain selling expenses, is at least $5.0 million. Upon receipt of this request, the holders of registrable securities will each be entitled to participate in this registration. The Issuer will not be required to effect such a registration if, within any twelve month period, it has already effected two registrations on Form S-3 for the holders of registrable securities.

9

Expenses of Registration

The Issuer is required to pay all expenses, including fees and expenses of one counsel to represent the selling stockholders, relating to any demand, piggyback or Form S-3 registration, other than underwriting discounts and commissions, stock transfer taxes and any additional fees of counsel for the selling stockholders, subject to specified conditions and limitations. The Issuer is not required to pay registration expenses if a demand registration request is withdrawn at the request of a majority of holders of registrable securities to be registered, unless holders of a majority of the registrable securities agree to forfeit their right to one demand registration.

The investors’ rights agreement contains customary cross-indemnification provisions, pursuant to which the Issuer is obligated to indemnify the selling stockholders in the event of material misstatements or omissions in the applicable registration statement attributable to it, and the selling stockholders are obligated to indemnify the Issuer for material misstatements or omissions in the registration statement attributable to them, subject to certain limitations.

Termination of Registration Rights

The registration rights granted under the investors’ rights agreement will terminate with respect to any particular stockholder upon the earlier of (i) the closing of a deemed liquidation event, as defined in the Issuer’s certificate of incorporation; (ii) with respect to each stockholder, at such time such stockholder is able to sell all of its shares pursuant to Rule 144 or another similar exemption under the Securities Act during a three-month period without registration; and (iii) February 9, 2026 (the fifth anniversary of the closing of the IPO).

Lock-Up Agreements

5AM VI, 5AM Opportunities and Dr. Parmar, along with all of the Issuer’s executive officers and directors and holdres of substantially all of the the Issuer’s Common Stock prior to the IPO, have entered into lock-up agreements with the underwriters of the IPO pursuant to which such persons have generally agreed, subject to certain exceptions, that they will not,directly or indirectly, offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale, or otherwise dispose of or hedge any of their shares of Common Stock, any options or warrants to purchase shares of Common Stock, or any securities convertible into, or exchangeable for or that represent the right to receive shares of Common Stock, without the prior written consent of Goldman Sachs & Co. LLC, Evercore Group L.L.C, Barclays Capital Inc. and Stifel, Nicolaus & Company, Incorporated for a period of 180 days from February 4, 2021.

Other than as described in this Item 6, to the knowledge of the Reporting Persons, there are no contracts, arrangements, understandings or relationships (legal or otherwise) between the Reporting Persons and any person with respect to any securities of the Issuer, including, but not limited to, the transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies or any pledge or contingency, the occurrence of which would give another person voting or investment power of the securities of the Issuer.

Re: Vor Biopharma Inc. - Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the “Representatives”), propose to enter into an Underwriting Agreement on behalf of the several Underwriters named in Schedule I to such agreement (collectively, the “Underwriters”), with Vor Biopharma Inc., a Delaware corporation (the “Company”), providing for a public offering (the “Offering”) of shares (the “Shares”) of common stock of the Company, par value $0.0001 per share (the “Common Stock”), pursuant to a Registration Statement on Form S-1 to be filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriters to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the date of this Lock-Up Agreement and continuing to and including the date 180 days after the date set forth on the final prospectus used to sell the Shares (the “Lock-Up Period”), the undersigned shall not, and shall not cause or direct any of its affiliates to, (i) offer, sell, contract to sell, pledge, grant any option to purchase, lend or otherwise dispose of any shares of Common Stock, or any options or warrants to purchase any shares of Common Stock, or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock (such options, warrants or other securities, collectively, “Derivative Instruments”), including without limitation any such shares or Derivative Instruments now owned or hereafter acquired by the undersigned, (ii) engage in any hedging or other transaction or

arrangement (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) which is designed to or which reasonably could be expected to lead to or result in a sale, loan, pledge or other disposition (whether by the undersigned or someone other than the undersigned), or transfer of any of the economic consequences of ownership, in whole or in part, directly or indirectly, of any shares of Common Stock or Derivative Instruments, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Common Stock or other securities, in cash or otherwise (any such sale, loan, pledge or other disposition, or transfer of economic consequences, a “Transfer”) or (iii) otherwise publicly announce any intention to engage in or cause any action or activity described in clause (i) above or transaction or arrangement described in clause (ii) above. The undersigned represents and warrants that the undersigned is not, and has not caused or directed any of its affiliates to be or become, currently a party to any agreement or arrangement that provides for, is designed to or which reasonably could be expected to lead to or result in any Transfer during the Lock-Up Period. If the undersigned is an officer or director of the Company, the undersigned agrees that the foregoing provisions shall be equally applicable to any issuer-directed or other Shares the undersigned may purchase in the Offering.

If the undersigned is not a natural person, the undersigned represents and warrants that no single natural person, entity or “group” (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), other than a natural person, entity or “group” (as described above) that has executed a Lock-Up Agreement in substantially the same form as this Lock-Up Agreement, beneficially owns, directly or indirectly, 50% or more of the common equity interests, or 50% or more of the voting power, in the undersigned.

If the undersigned is an officer or director of the Company, (i) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of shares of Common Stock, the Representatives will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Representatives hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this letter to the extent and for the duration that such terms remain in effect at the time of the transfer.

Notwithstanding the foregoing, the undersigned may transfer or otherwise dispose of the undersigned’s shares of Common Stock or Derivative Instruments:

(i) as a bona fide gift or gifts or as a charitable contribution;

(ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family (as defined below) of the undersigned, or if the undersigned is a trust, to a beneficiary of the trust or to the estate of the beneficiary of such trust;

(iii) in connection with the sale of Common Stock (a) acquired in the Offering (other than any Company-directed Shares acquired by an officer or director of the Company) or (b) acquired in open market transactions after the Offering; provided that if any filing under Section 16(a) of the Exchange Act or other public filing, report or announcement reporting a reduction in beneficial ownership of

shares of Common Stock in connection with such transfer or distribution shall be legally required during the Lock-Up Period, such filing, report or announcement shall clearly indicate in the footnotes thereto the nature and conditions of such transfer;

(iv) if the undersigned is a corporation, partnership, limited liability company, trust or other business entity (a) to another corporation, partnership, limited liability company, trust or other business entity that is an affiliate (as defined in Rule 405 promulgated under the Securities Act of 1933, as amended) of the undersigned, or to any investment fund or other entity controlled or managed by the undersigned or affiliates of the undersigned, or (b) as part of a distribution, transfer or disposition without consideration by the undersigned to its stockholders, partners, members, beneficiaries or other equity holders;

(v) to the Company in connection with the exercise, vesting, exchange or settlement of options, warrants or other rights to acquire shares of Common Stock, including any security convertible into, exchangeable for or that represent the right to receive shares of Common Stock, in accordance with their terms (including the vesting or settlement of restricted stock units and including, in each case, by way of net exercise and/or to cover withholding tax obligations in connection with such exercise, vesting, exchange or settlement) pursuant to an employee benefit plan, option, warrant or other right disclosed in the final prospectus for the Offering, provided that any such shares issued upon exercise, vesting, exchange or settlement of such option, warrant, restricted stock unit or other right (in the case of a net exercise or tax withholding transaction, after giving effect to the settlement of such net exercise or tax withholding transaction) shall be subject to the restrictions on transfer set forth herein; provided that any filing under Section 16 of the Exchange Act reporting a change in beneficial ownership shall indicate in the footnotes thereto that the filing relates to the applicable circumstances described in this clause, and no other public announcement shall be required or shall be made voluntarily in connection with such transfer;

(vi) by will or intestacy, provided that no public filing, report or announcement shall be voluntarily made and, if required, any public report or filing under Section 16 of the Exchange Act shall clearly indicate in the footnotes thereto that the filing relates to the transfer of shares by will or intestacy;

(vii) to any immediate family member of the undersigned;

(viii) by operation of law or pursuant to a court order or a settlement agreement related to the distribution of assets in connection with the dissolution of a marriage, domestic partnership or civil union, provided that no public filing, report or announcement shall be voluntarily made and, if required, any public report or filing under Section 16 of the Exchange Act shall clearly indicate in the footnotes thereto that the filing relates to the transfer of shares by operation of law or pursuant to a court order or a settlement agreement related to the distribution of assets in connection with the dissolution of a marriage, domestic partnership or civil union, as the case may be;

(ix) to the Company pursuant to agreements under which the Company has (a) the option to repurchase such securities or (b) a right of first refusal with respect to transfers of such securities, in each case upon termination of service of the undersigned; provided that any filing under Section 16 of the Exchange Act reporting a change in beneficial ownership shall indicate in the footnotes thereto that the filing relates to the applicable circumstances described in this clause, and no other public announcement shall be required or shall be made voluntarily in connection with such transfer;

(x) in connection with the conversion of outstanding shares of the Company’s preferred stock into Common Stock as described in the Registration Statement relating to the Offering, or any reclassification or conversion of the Common Stock; provided that any Common Stock received

upon such conversion or reclassification will be subject to the restrictions set forth in this paragraph; and

(xi) with the prior written consent of the Representatives on behalf of the Underwriters.

Additionally, the undersigned may establish a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of the Undersigned’s Shares, provided that such plan does not provide for any transfers of Common Stock during the Lock-Up Period and no filing under the Exchange Act nor any other public filing, announcement or disclosure of such trading plan shall be made during the Lock-Up Period.

Further, this Lock-Up Agreement shall not restrict any sale, disposal or transfer of the undersigned’s shares of Common Stock or Derivative Instruments to a bona fide third party pursuant to a tender offer for securities of the Company or any merger, consolidation or other business combination involving a Change of Control (as defined below) of the Company occurring after the settlement of the Offering, that, in each case, has been approved by the board of directors of the Company; provided that all of the undersigned’s shares of Common Stock and Derivative Instruments subject to this Lock-Up Agreement that are not so transferred, sold, tendered or otherwise disposed of remain subject to this Lock-Up Agreement; and provided, further, that it shall be a condition of transfer, sale, tender or other disposition that if such tender offer or other transaction is not completed, any of the undersigned’s shares of Common Stock or Derivative Instruments subject to this Lock-Up Agreement shall remain subject to the restrictions on transfer set forth herein. For the purposes of this paragraph, “Change of Control” means the consummation of any bona fide third party tender offer, merger, consolidation or other similar transaction, the result of which is that any “person” (as defined in Section 13(d)(3) of the Exchange Act), or group of persons, other than the Company or its subsidiaries, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act) of at least 50% of the total voting power of the voting share capital of the Company.

In addition, in the case of transfers pursuant to clauses (a)(i), (ii), (iv), (vi), (vii) and (viii) above, it shall be a condition to such transfer that each transferee, donee or distributee sign and deliver a lock-up agreement substantially in the form of this Lock-Up Agreement, except in the case of clauses (a)(vi) and (viii) where a court of competent jurisdiction requires such transfer or distribution be made without such a restriction; provided further that in the case of transfers pursuant to clauses (a)(i), (ii), (iv) and (vii) above, no filing under Section 16(a) of the Exchange Act or other public announcement reporting a reduction in beneficial ownership of the undersigned’s shares of Common Stock shall be required or shall be voluntarily made during the Lock-Up Period; and provided further in the case of transfers pursuant to clauses (a)(i), (ii), (vi) and (vii) above, any such transfer shall not involve a disposition for value.

For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

In the event that a holder of at least one percent (1%) of the then outstanding Common Stock (calculated on an as-converted, fully-diluted basis and as of the close of business on the date of the final prospectus used to sell the Shares) who is a party to a lock-up agreement with the Representatives with respect to the Offering (each a “Major Holder” and, collectively, the “Major Holders”) is released from its obligations under such lockup agreement, then the same percentage of the total number of outstanding Common Stock held by the undersigned as the percentage of the total number of outstanding Common Stock held by such Major Holder that are the subject of such waiver shall be immediately and fully released on the same terms from the applicable

prohibition(s) set forth herein (the “Pro-Rata Release”); provided that (i) the Representatives shall use their commercially reasonable efforts to provide notice to the Company within two business days of any Pro Rata Release setting forth the number of shares of Common Stock proposed to be released (provided that the failure to provide such notice shall not give rise to any claim or liability against the Representatives or the Underwriters), (ii) upon receipt of such notice from the Representatives, the Company will notify the undersigned of the requested release within five business days, and (iii) the undersigned may require a Pro Rata Release by the Representatives from the terms of this Lock-Up Agreement by (x) providing notice in writing to the Representatives of such requirement and (y) certifying in writing to the Representatives and the Company the total number of shares of Common Stock held by such shareholder as of the time of the request of the Pro Rata Release. If the Company fails to notify the undersigned within five business days of the request of the Release, the failure to give such notice shall not give rise to any claim or liability against the Representatives or the Underwriters.

The Pro Rata Release shall not apply (a)(1) to the extent that the aggregate holding percentage of the Common Stock subject to any such releases or waivers is less than or equal to 1% of the shares of Common Stock outstanding prior to the completion of the Offering (calculated on an as-converted, fully-diluted basis and as of the close of business on the date set forth on the final prospectus used to sell the Shares), (2) if (x) the release or waiver is effected solely to permit a transfer not involving a disposition for value, and (y) the transferee agrees in writing to be bound by the same terms described in this Lock-Up Agreement to the extent and for the duration that such terms remain in effect at the time of transfer, (b) if the release, in full or in part, of any Common Stock from the restrictions of a lock-up agreement is in connection with an underwritten follow-on offering that includes such released shares of Common Stock (the “Follow-On Offering”) where the undersigned has been given the opportunity to participate in such Follow-On Offering on a pro rata basis and otherwise on the same terms as any other equity holders participating in such Follow-on Offering, then the Common Stock held by the undersigned shall be released only if the undersigned enters into a new lock-up letter with the underwriters or that Follow-On Offering with respect to the Lock-Up Securities that are not being released, upon terms and conditions reasonably satisfactory to such underwriters but with restrictions that will be no more restrictive than those applicable to any other shareholder participating in the Follow-On Offering or as set forth herein (other than that the expiration of the new lock-up may be up to 90 days from the date of such Follow-On Offering) and only to the extent that the undersigned agrees to participate as a selling stockholder in the Follow- On Offering and to sell any of the Common Stock released from the restrictions of this Lock-Up Agreement in such Follow-On Offering, or (c) if the release or waiver is granted due to circumstances of an emergency or hardship as determined by the Representatives in their sole judgment.

The undersigned now has, and, except as contemplated above, for the duration of this Lock- Up Agreement will have, good and marketable title to the undersigned’s shares of Common Stock , free and clear of all liens, encumbrances, and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

This Lock-Up Agreement (and, for the avoidance of doubt, the Lock-Up Period described herein) and related restrictions shall automatically terminate and be of no further force and effect upon the earlier to occur of: (i) the Company advising the Underwriters in writing prior to the execution of the Underwriting Agreement that it does not intend to proceed with the Offering; (ii) the termination of the Underwriting Agreement before the closing of the Offering; (iii) the registration

not been executed by that date; provided, however, that the Company may, by written notice to you prior to such date, extend such date for a period of up to an additional 90 days.
