2.1 Right of First Refusal. 

(a) Grant. Subject to the terms of Section 3 below, each Key Holder hereby unconditionally and irrevocably
grants to the Company a Right of First Refusal to purchase all or any portion of Transfer Stock that such Key Holder may propose to transfer in a Proposed Key Holder Transfer, at the same price and on the same terms and conditions as those offered
to the Prospective Transferee. 

  
 3 













 (b) Notice. Each Key Holder proposing to make a Proposed Key Holder Transfer must
deliver a Proposed Transfer Notice to the Company and each Investor not later than [***] prior to the consummation of such Proposed Key Holder Transfer. Such Proposed Transfer Notice shall contain the material terms and conditions (including price
and form of consideration) of the Proposed Key Holder Transfer, the identity of the Prospective Transferee and the intended date of the Proposed Key Holder Transfer. To exercise its Right of First Refusal under this
Section 2, the Company must deliver a Company Notice to the selling Key Holder within [***] after delivery of the Proposed Transfer Notice specifying the number of shares of Transfer Stock to be purchased by the Company. In
the event of a conflict between this Agreement and any other agreement that may have been entered into by a Key Holder with the Company that contains a preexisting right of first refusal, the Company and the Key Holder acknowledge and agree that the
terms of this Agreement shall control and the preexisting Right of First Refusal shall be deemed satisfied by compliance with Section 2.1(a) and this Section 2.1 (b).  

(c) Grant of Secondary Refusal Right to Investors. Subject to the terms of Section 3 below, each Key Holder
hereby unconditionally and irrevocably grants to the Investors a Secondary Refusal Right to purchase all or any portion of the Transfer Stock not purchased by the Company pursuant to the Right of First Refusal, as provided in this
Section 2.1(c). If the Company does not provide the Company Notice exercising its Right of First Refusal with respect to all Transfer Stock subject to a Proposed Key Holder Transfer, the Company must deliver a Secondary
Notice to the selling Key Holder and to each Investor to that effect no later than [***] after the selling Key Holder delivers the Proposed Transfer Notice to the Company. To exercise its Secondary Refusal Right, an Investor must deliver an Investor
Notice to the selling Key Holder and the Company within [***] after the Company’s deadline for its delivery of the Secondary Notice as provided in the preceding sentence. 

(d) Undersubscription of Transfer Stock. If options to purchase have been exercised by the Company and the Investors with respect to
some but not all of the Transfer Stock by the end of the [***] specified in the last sentence of Section 2.1(c)) (the “Investor Notice Period”), then the Company shall, within [***] after the expiration of
the Investor Notice Period, send written notice (the “Company Undersubscription Notice”) to those Investors who fully exercised their Secondary Refusal Right within the Investor Notice Period (the “Exercising
Investors”). Each Exercising Investor shall, subject to the provisions of this Section 2.1(d), have an additional option to purchase all or any part of the balance of any such remaining unsubscribed shares of
Transfer Stock on the terms and conditions set forth in the Proposed Transfer Notice. To exercise such option, an Exercising Investor must deliver an Undersubscription Notice to the selling Key Holder and the Company within [***] after the
expiration of the Investor Notice Period. In the event there are [***] or more such Exercising Investors that choose to exercise the last-mentioned option for a total number of remaining shares in excess of the number available, the remaining shares
available for purchase under this Section 2.1(d) shall be allocated to such Exercising Investors pro rata based on the number of shares of Transfer Stock such Exercising Investors have elected to purchase pursuant to the


  
 4 













 
Secondary Refusal Right (without giving effect to any shares of Transfer Stock that any such Exercising Investor has elected to purchase pursuant to the Company Undersubscription Notice). If the
options to purchase the remaining shares are exercised in full by the Exercising Investors, the Company shall immediately notify all of the Exercising Investors and the selling Key Holder of that fact. 

(e) Consideration; Closing. If the consideration proposed to be paid for the Transfer Stock is in property, services or other non-cash consideration, the fair market value of the consideration shall be as determined in good faith by the Board of Directors and as set forth in the Company Notice. If the Company or any Investor cannot for any
reason pay for the Transfer Stock in the same form of non-cash consideration, the Company or such Investor may pay the cash value equivalent thereof, as determined in good faith by the Board of Directors and
as set forth in the Company Notice. The closing of the purchase of Transfer Stock by the Company and the Investors shall take place, and all payments from the Company and the Investors shall have been delivered to the selling Key Holder, by the
later of (i) the date specified in the Proposed Transfer Notice as the intended date of the Proposed Key Holder Transfer and (ii) [***] after delivery of the Proposed Transfer Notice. 

2.2 Right of Co-Sale. 

(a) Exercise of Right. If any Transfer Stock subject to a Proposed Key Holder Transfer is not purchased pursuant to
Section 2.1 above and thereafter is to be sold to a Prospective Transferee, each respective Investor may elect to exercise its Right of Co-Sale and participate on a pro rata basis in
the Proposed Key Holder Transfer as set forth in Section 2.2(b) below and otherwise on the same terms and conditions specified in the Proposed Transfer Notice (provided that if an Investor wishes to sell Preferred Stock,
the price set forth in the Proposed Transfer Notice shall be appropriately adjusted based on the conversion ratio of the Preferred Stock into Common Stock). Each Investor who desires to exercise its Right of
Co-Sale must give the selling Key Holder written notice to that effect within [***] after the deadline for delivery of the Secondary Notice described above, and upon giving such notice such Investor shall be
deemed to have effectively exercised the Right of Co-Sale. 
 (b) Shares Includable. Each
Participating Investor may include in the Proposed Key Holder Transfer all or any part of such Participating Investor’s Capital Stock equal to the product obtained by multiplying (i) the aggregate number of shares of Transfer Stock subject
to the Proposed Key Holder Transfer (excluding shares purchased by the Company or the Participating Investors pursuant to the Right of First Refusal or the Secondary Refusal Right) by (ii) a fraction, the numerator of which is the number of
shares of Capital Stock owned by such Participating Investor immediately before consummation of the Proposed Key Holder Transfer (including any shares that such Participating Investor has agreed to purchase pursuant to the Secondary Refusal Right)
and the denominator of which is the total number of shares of Capital Stock owned, in the aggregate, by all Participating Investors immediately prior to the consummation of the Proposed Key Holder Transfer (including any shares that all
Participating Investors have collectively agreed to purchase pursuant to the Secondary Refusal Right), plus the number of shares of Transfer Stock held by the selling Key Holder. To the extent one (1) or more of the Participating Investors
exercise such right of participation in accordance with the terms and conditions set forth herein, the number of shares of Transfer Stock that the selling Key Holder may sell in the Proposed Key Holder Transfer shall be correspondingly reduced.

 (c) Purchase and Sale Agreement. The Participating Investors and the selling Key
Holder agree that the terms and conditions of any Proposed Key Holder Transfer in accordance with this Subsection 2.2(c) will be memorialized in, and governed by, a written purchase and sale agreement with the Prospective Transferee (the
“Purchase and Sale Agreement”) with customary terms and provisions for such a transaction, and the Participating Investors and the selling Key Holder further covenant and agree to enter into such Purchase and Sale Agreement as a
condition precedent to any sale or other transfer in accordance with this Subsection 2.2. 
 (d) Allocation of Consideration.

 (i) Subject to Subsection 2.2(d)(ii), the aggregate consideration payable to the Participating Investors and the selling Key
Holder shall be allocated based on the number of shares of Capital Stock sold to the Prospective Transferee by each Participating Investor and the selling Key Holder as provided in Subsection 2.2(a), provided that if a Participating
Investor wishes to sell Preferred Stock, the price set forth in the Proposed Transfer Notice shall be appropriately adjusted based on the conversion ratio of the Preferred Stock into Common Stock. 

(ii) In the event that the Proposed Key Holder Transfer constitutes a Change of Control, the terms of the Purchase and Sale Agreement shall
provide that the aggregate consideration from such transfer shall be allocated to the Participating Investors and the selling Key Holder in accordance with Sections 2.1 and 2.2 of Article IV(B) of the Restated Certificate and, if applicable, the
next sentence as if (A) such transfer were a Deemed Liquidation Event (as defined in the Restated Certificate), and (B) the Capital Stock sold in accordance with the Purchase and Sale Agreement were the only Capital Stock outstanding. In
the event that a portion of the aggregate consideration payable to the Participating Investor(s) and selling Key Holder is placed into escrow and/or is payable only upon satisfaction of contingencies, the Purchase and Sale Agreement shall provide
that (x) the portion of such consideration that is not placed in escrow and is not subject to contingencies (the “Initial Consideration”) shall be allocated in accordance with Sections 2.1 and 2.2 of Article IV(B) of the
Restated Certificate as if the Initial Consideration were the only consideration payable in connection with such transfer, and (y) any additional consideration which becomes payable to the Participating Investor(s) and selling Key Holder upon
release from escrow or satisfaction of such contingencies shall be allocated in accordance with Sections 2.1 and 2.2 of Article IV(B) of the Restated Certificate after taking into account the previous payment of the Initial Consideration as part of
the same transfer. 
 (e) Purchase by Selling Key Holder; Deliveries. Notwithstanding Subsection 2.2(c) above, if any
Prospective Transferee or Transferees refuse(s) to purchase securities subject to the Right of Co-Sale from any Participating Investor or Investors or upon the failure to negotiate in good faith a Purchase and
Sale Agreement reasonably satisfactory to the Participating Investors, no Key Holder may sell any Transfer Stock to such Prospective Transferee or Transferees unless and until, simultaneously with such sale, such Key Holder


  
 6 













 
purchases all securities subject to the Right of Co-Sale from such Participating Investor or Investors on the same terms and conditions (including the
proposed purchase price) as set forth in the Proposed Transfer Notice and as provided in Subsection 2.2(d)(i); provided, however, if such sale constitutes a Change of Control, the portion of the aggregate consideration
paid by the selling Key Holder to such Participating Investor or Investors shall be made in accordance with the first sentence of Subsection 2.2(d)(ii). In connection with such purchase by the selling Key Holder, such Participating Investor
or Investors shall deliver to the selling Key Holder any stock certificate or certificates, properly endorsed for transfer, representing the Capital Stock being purchased by the selling Key Holder (or request that the Company effect such transfer in
the name of the selling Key Holder). Any such shares transferred to the selling Key Holder will be transferred to the Prospective Transferee against payment therefor in consummation of the sale of the Transfer Stock pursuant to the terms and
conditions specified in the Proposed Transfer Notice, and the selling Key Holder shall concurrently therewith remit or direct payment to each such Participating Investor the portion of the aggregate consideration to which each such Participating
Investor is entitled by reason of its participation in such sale as provided in this Subsection 2.2(e). 
 (f) Additional
Compliance. If any Proposed Key Holder Transfer is not consummated within [***] after receipt of the Proposed Transfer Notice by the Company, the Key Holders proposing the Proposed Key Holder Transfer may not sell any Transfer Stock unless they
first comply in full with each provision of this Section 2. The exercise or election not to exercise any right by any Investor hereunder shall not adversely affect its right to participate in any other sales of Transfer
Stock subject to this Section 2.2. 
 2.3 Effect of Failure to Comply. 

(a) Transfer Void; Equitable Relief. Any Proposed Key Holder Transfer not made in compliance with the requirements of this Agreement
shall be null and void ab initio, shall not be recorded on the books of the Company or its transfer agent and shall not be recognized by the Company. Each party hereto acknowledges and agrees that any breach of this Agreement would result in
substantial harm to the other parties hereto for which monetary damages alone could not adequately compensate. Therefore, the parties hereto unconditionally and irrevocably agree that any non-breaching party
hereto shall be entitled to seek protective orders, injunctive relief and other remedies available at law or in equity (including, without limitation, seeking specific performance or the rescission of purchases, sales and other transfers of Transfer
Stock not made in strict compliance with this Agreement). 
 (b) Violation of First Refusal Right. If any Key Holder becomes
obligated to sell any Transfer Stock to the Company or any Investor under this Agreement and fails to deliver such Transfer Stock in accordance with the terms of this Agreement, the Company and/or such Investor may, at its option, in addition to all
other remedies it may have, send to such Key Holder the purchase price for such Transfer Stock as is herein specified and transfer to the name of the Company or such Investor (or request that the Company effect such transfer in the name of an
Investor) on the Company’s books any certificates, instruments, or book entry representing the Transfer Stock to be sold. 

  
 7 













 (c) Violation of Co-Sale Right. If any Key
Holder purports to sell any Transfer Stock in contravention of the Right of Co-Sale (a “Prohibited Transfer”), each Investor who desires to exercise its Right of
Co-Sale under Section 2.2 may, in addition to such remedies as may be available by law, in equity or hereunder, require such Key Holder to purchase from such Investor the type and
number of shares of Capital Stock that such Investor would have been entitled to sell to the Prospective Transferee under Section 2.2 had the Prohibited Transfer been effected pursuant to and in compliance with the terms of
Section 2.2. The sale will be made on the same terms and subject to the same conditions as would have applied had the Key Holder not made the Prohibited Transfer, except that the sale (including, without limitation, the
delivery of the purchase price) must be made within [***] after the Investor learns of the Prohibited Transfer, as opposed to the timeframe proscribed in Section 2.2. Such Key Holder shall also reimburse each Investor for
any and all reasonable and documented out-of-pocket fees and expenses, including reasonable legal fees and expenses, incurred pursuant to the exercise or the attempted
exercise of the Investor’s rights under Section 2.2. 
 3. Exempt Transfers. 

3.1 Exempted Transfers. Notwithstanding the foregoing or anything to the contrary herein, the provisions of Sections 2.1 and
2.2 shall not apply: (a) in the case of a Key Holder that is an entity, upon a transfer by such Key Holder to its stockholders, members, partners or other equity holders, (b) to a repurchase of Transfer Stock from a Key Holder by
the Company at a price no greater than that originally paid by such Key Holder for such Transfer Stock and pursuant to an agreement containing vesting and/or repurchase provisions approved by a majority of the Board of Directors or any duly formed
compensation committee thereof, or (c) in the case of a Key Holder that is a natural person, upon a transfer of Transfer Stock by such Key Holder made for bona fide estate planning purposes, either during his or her lifetime or on death by will
or intestacy to his or her spouse, child (natural or adopted), or any other direct lineal descendant of such Key Holder (or his or her spouse) (all of the foregoing collectively referred to as “family members”), or any other person
approved by the Board of Directors, or any custodian or trustee of any trust, partnership or limited liability company for the benefit of, or the ownership interests of which are owned wholly by, such Key Holder or any such family members,
provided that in the case of clauses(s) (a) or (c), the Key Holder shall deliver prior written notice to the Investors of such gift or transfer and such shares of Transfer Stock shall at all times remain subject to the terms and
restrictions set forth in this Agreement and such transferee shall, as a condition to such issuance, deliver a counterpart signature page to this Agreement as confirmation that such transferee shall be bound by all the terms and conditions of this
Agreement as a Key Holder (but only with respect to the securities so transferred to the transferee), including the obligations of a Key Holder with respect to Proposed Key Holder Transfers of such Transfer Stock pursuant to
Section 2. 
 3.2 Exempted Offerings. Notwithstanding the foregoing or anything to the contrary herein, the
provisions of Section 2 shall not apply to the sale of any Transfer Stock (a) to the public in an offering pursuant to an effective registration statement under the Securities Act of 1933, as amended (a “Public
Offering”) or (b) pursuant to a Deemed Liquidation Event (as defined in the Restated Certificate). 

  
 8 













 4. Legend. Each certificate, instrument or book entry representing shares of Transfer Stock held by
the Key Holders or issued to any permitted transferee in connection with a transfer permitted by Section 3(a) hereof shall be endorsed with the following legend: 

THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES REPRESENTED HEREBY IS SUBJECT TO, AND IN CERTAIN CASES PROHIBITED BY, THE TERMS
AND CONDITIONS OF A CERTAIN AMENDED AND RESTATED RIGHT OF FIRST REFUSAL AND CO-SALE AGREEMENT BY AND AMONG THE STOCKHOLDER, THE CORPORATION AND CERTAIN OTHER HOLDERS OF STOCK OF THE CORPORATION. COPIES OF SUCH
AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE CORPORATION. 
 Each Key Holder agrees that the Company may instruct its transfer
agent to impose transfer restrictions on the shares represented by certificates bearing the legend referred to in this Section 4 above to enforce the provisions of this Agreement, and the Company agrees to promptly do so.
The legend shall be removed upon termination of this Agreement at the request of the holder. 
 5. Lock-Up.

 5.1 Agreement to Lock-Up. Each Key Holder hereby agrees that it will not, without the
prior written consent of the managing underwriter, during the period commencing on the date of the final prospectus relating to the Company’s initial public offering (the “IPO”) and ending on the date specified by the Company

immediately prior to the effectiveness of the registration statement for the IPO or (b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Capital
Stock, whether any such transaction described in clause (a) or (b) above is to be settled by delivery of Capital Stock or other securities, in cash or otherwise (the “Lock-Up”).
[***] The underwriters in connection with the IPO are intended third-party beneficiaries of this Section 5 and shall have the right, power and authority to enforce the provisions
hereof as though they were a party hereto. Each Key Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in the IPO that are consistent with this Section 5 or that are
necessary to give further effect thereto. 
 5.2 Stop Transfer Instructions. In order to enforce the foregoing covenant, the Company
may impose stop-transfer instructions with respect to the shares of Capital Stock of each Key Holder (and transferees and assignees thereof) until the end of such restricted period.

6.2 Stock Split. All references to numbers of shares in this Agreement shall be appropriately adjusted to reflect any stock dividend,
split, combination or other recapitalization affecting the Capital Stock occurring after the date of this Agreement.

than a community property interest as to which the holder thereof has acknowledged and agreed in writing to the restrictions and obligations hereunder). 

6.4 Dispute Resolution. Any unresolved controversy or claim arising out of or relating to this Agreement, except as (i) otherwise
provided in this Agreement, or (ii) any such controversies or claims arising out of either party’s intellectual property rights for which a provisional remedy or equitable relief is sought, shall be submitted to arbitration by one

having reasonable experience in corporate finance transactions of the type provided for in this Agreement and who is chosen by the AAA. The arbitration shall take place in Boston, Massachusetts, in accordance with the AAA rules then in effect, and
judgment upon any award rendered in such arbitration will be binding and may be entered in any court having jurisdiction thereof. There shall be limited discovery prior to the arbitration hearing as follows: (a) exchange of witness lists and
copies of documentary evidence and documents relating to or arising out of the issues to be arbitrated, (b) depositions of all party witnesses and (c) such other depositions as may be allowed by the arbitrators upon a showing of good
cause. Depositions shall be conducted in accordance with the Delaware Code of Civil Procedure, the arbitrator shall be required to provide in writing to the parties the basis for the award or order of such arbitrator, and a court reporter shall
record all hearings, with such record constituting the official transcript of such proceedings. The prevailing party shall be entitled to reasonable attorney’s fees, costs, and necessary disbursements in addition to any other relief to which
such party may be entitled.

Company of any change in its electronic mail address, and that failure to do so shall not affect the foregoing. 
 6.6 Entire
Agreement. This Agreement (including the Exhibits and Schedules hereto) constitutes the full and entire understanding and agreement between the parties with respect to the subject matter hereof, and any other written or oral agreement relating
to the subject matter hereof existing between the parties are expressly canceled. 
 6.7 Delays or Omissions. No delay or omission to
exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power or remedy of such
non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach
or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part
of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such
writing. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

 6.8 Amendment; Waiver and Termination. This Agreement may be amended, modified or
terminated (other than pursuant to Section 6.1 above) and the observance of any term hereof may be waived (either generally or in a particular instance and either retroactively or prospectively) only by a written instrument
executed by (a) the Company, (b) the Key Holders holding at least [***] of the shares of Transfer Stock then held by all of the Key Holders, and (c) the holders of a majority of the shares of Common Stock issued or issuable upon
conversion of the then outstanding shares of Preferred Stock held by the Investors (voting as a single class and on an as-converted basis). Any amendment, modification, termination or waiver so effected shall
be binding upon the Company, the Investors, the Key Holders and all of their respective successors and permitted assigns whether or not such party, assignee or other shareholder entered into or approved such amendment, modification, termination or
waiver. Notwithstanding the foregoing, (i) this Agreement may not be amended, modified or terminated and the observance of any term hereunder may not be waived with respect to any Investor or Key Holder without the written consent of such
Investor or Key Holder unless such amendment, modification, termination or waiver applies to all Investors and Key Holders, respectively, in the same fashion and (ii) the consent of the Key Holders shall not be required for any amendment,
modification, termination or waiver if such amendment, modification, termination or waiver does not apply to the Key Holders; provided, however this Agreement may be amended with only the written consent of the Company for the sole
purpose of updating Schedule B hereto for issuances of Common Stock after the date hereof. The Company shall give prompt written notice of any amendment, modification or termination hereof or waiver hereunder to any party hereto that did not
consent in writing to such amendment, modification, termination or waiver. No waivers of or exceptions to any term, condition or provision of this Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or
continuing waiver of any such term, condition or provision. 
 6.9 Assignment of Rights. 

(a) The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and permitted
assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and permitted assigns any rights, remedies, obligations, or liabilities
under or by reason of this Agreement, except as expressly provided in this Agreement. 
 (b) Any successor or permitted assignee of any Key
Holder, including any Prospective Transferee who purchases shares of Transfer Stock in accordance with the terms hereof, shall deliver to the Company and the Investors, as a condition to any transfer or assignment, a counterpart signature page
hereto pursuant to which such successor or permitted assignee shall confirm their agreement to be subject to and bound by all of the provisions set forth in this Agreement that were applicable to the predecessor or assignor of such successor or
permitted assignee. 
 (c) The rights of the Investors hereunder are not assignable without the Company’s written consent (which shall
not be unreasonably withheld, delayed or conditioned), except (i) by an Investor to any Affiliate or (ii) to any assignee or transferee, it being acknowledged and agreed that any such assignment, including an assignment contemplated by the
preceding clauses (i) or (ii) shall be subject to and conditioned upon any such assignee’s delivery to the Company and the other Investors of a counterpart signature page hereto pursuant to which such assignee shall confirm their agreement
to be subject to and bound by all of the provisions set forth in this Agreement that were applicable to the assignor of such assignee.

acquirer of the Company, the rights and obligations of the Company hereunder may not be assigned under any circumstances.

principles that would result in the application of any law other than the law of the State of Delaware.

6.13 Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but
all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g.,

6.14 Aggregation of Stock. All shares of Capital Stock held or acquired by Affiliated entities or persons shall be aggregated together
for the purpose of determining the availability of any rights under this Agreement and such Affiliated persons may apportion such rights as among themselves in any manner they deem appropriate. 

6.15 Specific Performance. In addition to any and all other remedies that may be available at law in the event of any breach of this
Agreement, each Investor shall be entitled to specific performance of the agreements and obligations of the Company and the Key Holders hereunder and to such other injunction or other equitable relief as may be granted by a court of competent
jurisdiction. 
 6.16 Additional Key Holders. In the event that after the date of this Agreement, the Company issues shares of Common
Stock, or options to purchase Common Stock, to any employee or consultant, which shares or options would collectively constitute with respect to such employee or consultant (taking into account all shares of Common Stock, options and other purchase
rights held by such employee or consultant) [***] or more of the Company’s then outstanding Common Stock (treating for this purpose all shares of Common Stock issuable upon exercise of or conversion of outstanding options, warrants or
convertible securities, as if exercised or converted), the Company shall, as a condition to such issuance, cause such employee or consultant to execute a counterpart signature page hereto as a Key Holder, and such person shall thereby be bound by,
