 5 

 (e) Foreign Award Recipients. Notwithstanding any provision of the Plan to the

Award granted to individuals outside the United States to comply with applicable foreign laws; (iv) establish subplans and modify exercise procedures and other terms and procedures, to the extent the Administrator determines such actions to be

Section 3(a) hereof; and (v) take any action, before or after an Award is made, that the Administrator determines to be necessary or advisable to obtain approval or comply with any local governmental regulatory exemptions or

 SECTION 3. STOCK ISSUABLE UNDER THE PLAN; MERGERS AND OTHER TRANSACTIONS. 

(a) Stock Issuable. The maximum number of shares of Stock reserved and available for issuance under the Plan shall be 7,243,396 Shares,
subject to adjustment as provided in Section 3(b). For purposes of this limitation, the Shares underlying any Awards that are forfeited, canceled, reacquired by the Company prior to vesting, satisfied without the issuance of Stock or
otherwise terminated (other than by exercise) and Shares that are withheld upon exercise of an Option or settlement of an Award to cover the exercise price or tax withholding shall be added back to the Shares available for issuance under the Plan.
Subject to such overall limitations, Shares may be issued up to such maximum number pursuant to any type or types of Award. The Shares available for issuance under the Plan may be authorized but unissued Shares or Shares reacquired by the Company.

 (b) Changes in Stock. Subject to Section 3(c) hereof, if, as a result of any reorganization, recapitalization,
reclassification, stock dividend, stock split, reverse stock split or other similar change in the Company’s capital, the outstanding Shares are increased or decreased or are exchanged for a different number or kind of shares or other securities
of the Company, or additional Shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such Shares or other securities, in each case,
without the receipt of consideration by the Company, or, if, as a result of any merger or consolidation, or sale of all or substantially all of the assets of the Company, the outstanding Shares are converted into or exchanged for other securities of
the Company or any successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate and proportionate adjustment in (i) the maximum number of Shares reserved for issuance under the Plan, (ii) the number and
kind of Shares or other securities subject to any then outstanding Awards under the Plan, (iii) the repurchase price, if any, per Share subject to each outstanding Award, and (iv) the exercise price for each Share subject to any then
outstanding Stock Options under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of Stock Options) as to which such Stock Options remain exercisable. The Administrator shall in any event make
such adjustments as may be required by Section 25102(o) of the California Corporation Code and the rules and regulations promulgated thereunder. The adjustment by the Administrator shall be final, binding and conclusive. No fractional Shares
shall be issued under the Plan resulting from any such adjustment, but the Administrator in its discretion may make a cash payment in lieu of fractional shares. 

  
 6 

 (c) Sale Events. 

(i) Options. 

(A) In the case of and subject to the consummation of a Sale Event, the Plan and all outstanding Options issued hereunder shall
terminate upon the effective time of any such Sale Event unless assumed or continued by the successor entity, or new options or other awards of the successor entity or parent thereof are substituted therefor, with an equitable or proportionate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree (after taking into account any
acceleration pursuant to the terms of any Award Agreement). 
 (B) In the event of the termination of the Plan and all
outstanding Options issued hereunder pursuant to Section 3(c), each Holder of Options shall be permitted, within a period of time prior to the consummation of the Sale Event as specified by the Administrator, to exercise all such Options which
are then exercisable or will become exercisable as of the effective time of the Sale Event; provided, however, that the exercise of Options not exercisable prior to the Sale Event shall be subject to the consummation of the Sale Event. 

(C) Notwithstanding anything to the contrary in Section 3(c)(i)(A), in the event of a Sale Event, the Company shall have
the right, but not the obligation, to make or provide for a cash payment to the Holders of Options, without any consent of the Holders, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the value as
determined by the Administrator of the consideration payable per share of Stock pursuant to the Sale Event (the “Sale Price”) times the number of Shares subject to outstanding Options being cancelled (to the extent then vested and
exercisable, including by reason of acceleration in connection with such Sale Event, at prices not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding vested and exercisable Options. 

(ii) Restricted Stock Awards. 

(A) In the case of and subject to the consummation of a Sale Event, all unvested Restricted Stock Awards (other than those
becoming vested as a result of the Sale Event) issued hereunder shall be forfeited immediately prior to the effective time of any such Sale Event unless assumed or continued by the successor entity, or awards of the successor entity or parent
thereof are substituted therefor, with an equitable or proportionate adjustment as to the number and kind of shares subject to such awards as such parties shall agree (after taking into account any acceleration pursuant to the terms of any Award
Agreement). 

  
 7 

 (B) In the event of the forfeiture of unvested Restricted Stock pursuant to
Section 3(c)(ii)(A), such Restricted Stock shall be repurchased from the Holder thereof at a price per share equal to the original per share purchase price paid by the Holder (subject to adjustment as provided in Section 3(b)) for such
Shares. 
 (C) Notwithstanding anything to the contrary in Section 3(c)(ii)(A), in the event of a Sale Event, the
Company shall have the right, but not the obligation, to make or provide for a cash payment to the Holders of Restricted Stock, without consent of the Holders, in exchange for the cancellation thereof, in an amount equal to the Sale Price times the
number of Shares subject to such Awards, to be paid at the time of such Sale Event or upon the later vesting of such Awards. 
 SECTION 4.
ELIGIBILITY 
 Grantees under the Plan will be such full or part-time officers and other employees, directors, members of the
scientific advisory board, Consultants and key persons of the Company and any Subsidiary who are selected from time to time by the Administrator in its sole discretion; provided, however, that Awards shall be granted only to those
individuals described in Rule 701(c) of the Securities Act. 
 SECTION 5. STOCK OPTIONS 

Upon the grant of a Stock Option, the Company and the grantee shall enter into an Award Agreement. The terms and conditions of each such Award
Agreement shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. Stock Options granted under the Plan are not intended to qualify as “incentive stock options” as defined in
Section 422(b) of the Code. 
 (a) Terms of Stock Options. The Administrator in its discretion may grant Stock Options to those
individuals who meet the eligibility requirements of Section 4. Stock Options shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the
Administrator shall deem desirable. 
 (i) Exercise Price. The exercise price per share for the Shares covered by a Stock Option
shall be determined by the Administrator at the time of grant but shall not be less than 100 percent of the Fair Market Value on the Grant Date. 

(ii) Option Term. The term of each Stock Option shall be fixed by the Administrator, but no Stock Option shall be exercisable more than
ten years from the Grant Date. 
 (iii) Exercisability; Rights of a Stockholder. Stock Options shall become exercisable and/or vested
at such time or times, whether or not in installments, as shall be determined by the Administrator at or after the Grant Date. The Award Agreement may permit a grantee to exercise all or a portion of a Stock Option immediately at grant; provided
that the Shares issued upon such exercise shall be subject to restrictions and a vesting schedule identical to the vesting schedule of the related Stock Option, such Shares shall be deemed to be Restricted Stock for purposes of the Plan, and the
optionee may be required to enter into an additional or new Award Agreement as a condition to exercise of such Stock Option. The Award Agreement may provide that a Stock Option may only be exercised upon the prior written approval of the Board or
upon occurrence of some other event. An optionee shall have the rights of a 

  
 8 

 
stockholder only as to Shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options. An optionee shall not be deemed to have acquired any Shares unless and until a
Stock Option shall have been exercised pursuant to the terms of the Award Agreement and this Plan and the optionee’s name has been entered on the books of the Company as a stockholder. 

(iv) Method of Exercise. Stock Options may be exercised by an optionee in whole or in part, by the optionee giving written or
electronic notice of exercise to the Company, specifying the number of Shares to be purchased. Payment of the purchase price may be made by one or more of the following methods (or any combination thereof) to the extent provided in the Award
Agreement: 
 (A) In cash, by certified or bank check, by wire transfer of immediately available funds, or other instrument
acceptable to the Administrator; 
 (B) If permitted by the Administrator, by the optionee delivering to the Company a
promissory note, if the Board has expressly authorized the loan of funds to the optionee for the purpose of enabling or assisting the optionee to effect the exercise of his or her Stock Option; provided, that at least so much of the exercise
price as represents the par value of the Shares shall be paid in cash if required by state law; 
 (C) If permitted by the
Administrator and the IPO has occurred (or the Stock (or any security into which the Stock converted) otherwise become publicly-traded), through the delivery (or attestation to the ownership) of Shares that have been purchased by the optionee on the
open market or that are beneficially owned by the optionee and are not then subject to restrictions under any Company plan. To the extent required to avoid variable accounting treatment under ASC 718 or other applicable accounting rules, such
surrendered Shares if originally purchased from the Company shall have been owned by the optionee for at least six months. Such surrendered Shares shall be valued at Fair Market Value on the exercise date; 

(D) If permitted by the Administrator and the IPO has occurred (or the Stock (or any security into which the Stock converted)
otherwise become publicly-traded), by the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the
Company for the purchase price; provided that in the event the optionee chooses to pay the purchase price as so provided, the optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other
agreements as the Administrator shall prescribe as a condition of such payment procedure; or 
 (E) If permitted by the
Administrator, by a “net exercise” arrangement pursuant to which the Company will reduce the number of Shares issuable upon exercise by the largest whole number of Shares with a Fair Market Value that does not exceed the aggregate exercise
price. 

  
 9 

 Payment instruments will be received subject to collection. No certificates for Shares so
purchased will be issued to the optionee or, with respect to uncertificated Stock, no transfer to the optionee on the records of the Company will take place, until the Company has completed all steps it has deemed necessary to satisfy legal
requirements relating to the issuance and sale of the Shares, which steps may include, without limitation, (i) receipt of a representation from the optionee at the time of exercise of the Option that the optionee is purchasing the Shares for
the optionee’s own account and not with a view to any sale or distribution of the Shares or other representations relating to compliance with applicable law governing the issuance of securities, (ii) the legending of the certificate (or
notation on any book entry) representing the Shares to evidence the foregoing restrictions, and (iii) obtaining from optionee payment or provision for all withholding taxes due as a result of the exercise of the Option. The delivery of
certificates representing the Shares (or the transfer to the optionee on the records of the Company with respect to uncertificated Stock) to be purchased pursuant to the exercise of a Stock Option will be contingent upon (A) receipt from the
optionee (or a purchaser acting in his or her stead in accordance with the provisions of the Stock Option) by the Company of the full purchase price for such Shares and the fulfillment of any other requirements contained in the Award Agreement or
applicable provisions of laws and (B) if required by the Company, the optionee shall have entered into any stockholders agreements or other agreements with the Company and/or certain other of the Company’s stockholders relating to the
Stock. In the event an optionee chooses to pay the purchase price by previously-owned Shares through the attestation method, the number of Shares transferred to the optionee upon the exercise of the Stock Option shall be net of the number of Shares
attested to. 
 (b) Termination. Any portion of a Stock Option that is not vested and exercisable on the date of termination of an
optionee’s Service Relationship shall immediately expire and be null and void. Once any portion of the Stock Option becomes vested and exercisable, the optionee’s right to exercise such portion of the Stock Option (or the optionee’s
representatives and legatees as applicable) in the event of a termination of the optionee’s Service Relationship shall continue until the earliest of: (i) the date which is: (A) 12 months following the date on which the optionee’s
Service Relationship terminates due to death or Disability (or such longer period of time as determined by the Administrator and set forth in the applicable Award Agreement), or (B) three months following the date on which the optionee’s
Service Relationship terminates if the termination is due to any reason other than death or Disability (or such longer period of time as determined by the Administrator and set forth in the applicable Award Agreement), or (ii) the Expiration
Date set forth in the Award Agreement; provided that notwithstanding the foregoing, an Award Agreement may provide that if the optionee’s Service Relationship is terminated for Cause, the Stock Option shall terminate immediately and be
null and void upon the date of the optionee’s termination and shall not thereafter be exercisable. 
 SECTION 6. RESTRICTED STOCK AWARDS 

(a) Nature of Restricted Stock Awards. The Administrator may, in its sole discretion, grant, or sell at a purchase price determined by
the Administrator, to an eligible individual under Section 4 hereof a Restricted Stock Award under the Plan. The Administrator shall determine the restrictions and conditions applicable to each Restricted Stock Award at the time of grant.
Conditions may be based on continuing employment (or other Service Relationship), achievement of pre-established performance goals and objectives and/or such 

  
 10 

 
other criteria as the Administrator may determine. Upon the grant of a Restricted Stock Award, the Company and the grantee shall enter into an Award Agreement. The terms and conditions of each
such Award Agreement shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. 

(b) Rights as a Stockholder. Upon the grant of the Restricted Stock Award, payment of any applicable purchase price, and satisfaction
of any other conditions required by the Administrator, a grantee of Restricted Stock shall be considered the record owner of and shall be entitled to vote the Restricted Stock if, and to the extent, such Shares are entitled to voting rights, subject
to such conditions contained in the Award Agreement. The grantee shall be entitled to receive all dividends and any other distributions declared on the Shares; provided, however, that the Company is under no duty to declare any such
dividends or to make any such distribution. Unless the Administrator shall otherwise determine, certificates evidencing the Restricted Stock shall remain in the possession of the Company until such Restricted Stock are vested as provided in
subsection (d) below of this Section, and the grantee shall be required, as a condition of the grant, to deliver to the Company a stock power endorsed in blank and such other instruments of transfer as the Administrator may prescribe. 

(c) Restrictions. Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as
specifically provided herein or in the Award Agreement. Except as may otherwise be provided by the Administrator either in the Award Agreement or, subject to Section 11 below, in writing after the Award Agreement is issued, if a grantee’s
Service Relationship with the Company and any Subsidiary terminates, the Company or its assigns shall have the right, as may be specified in the relevant instrument, to repurchase some or all of the Shares subject to the Award at such purchase price
as is set forth in the Award Agreement. 
 (d) Vesting of Restricted Stock. The Administrator at the time of grant shall specify in
the Award Agreement the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the substantial risk of forfeiture imposed shall lapse and the
Restricted Stock shall become vested, subject to such further rights of the Company or its assigns as may be specified in the Award Agreement. 
 SECTION 7.
UNRESTRICTED STOCK AWARDS 
 The Administrator may, in its sole discretion, grant, or sell at such purchase price determined by the
Administrator, to an eligible person under Section 4 hereof an Unrestricted Stock Award under the Plan. Unrestricted Stock Awards may be granted in respect of past services or other valid consideration, or in lieu of cash compensation due to
such grantee. 
 SECTION 8. TRANSFER RESTRICTIONS; COMPANY RIGHT OF FIRST REFUSAL; COMPANY REPURCHASE RIGHTS 

(a) Restrictions on Transfer. 

  
 11 

 (i) Non-Transferability of Stock Options.
Stock Options and, prior to exercise, the Shares issuable upon exercise of such Stock Option, shall not be transferable by the optionee otherwise than by will, or by the laws of descent and distribution, and all Stock Options shall be exercisable,
during the optionee’s lifetime, only by the optionee, or by the optionee’s legal representative or guardian in the event of the optionee’s incapacity. Notwithstanding the foregoing, the Administrator, in its sole discretion, may
provide in the Award Agreement regarding a given Stock Option that the optionee may transfer by gift, without consideration for the transfer, his or her Stock Options to his or her family members (as defined in Rule 701 of the Securities Act), to
trusts for the benefit of such family members, or to partnerships in which such family members are the only partners (to the extent such trusts or partnerships are considered “family members” for purposes of Rule 701 of the Securities
Act), provided that the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Award Agreement, including the execution of a stock power upon the issuance of Shares. Stock
Options, and the Shares issuable upon exercise of such Stock Options, shall be restricted as to any pledge, hypothecation, or other transfer, including any short position, any “put equivalent position” (as defined in the Exchange Act) or
any “call equivalent position” (as defined in the Exchange Act) prior to exercise. 
 (ii) Shares. No Shares shall be sold,
assigned, transferred, pledged, hypothecated, given away or in any other manner disposed of or encumbered, whether voluntarily or by operation of law, unless (i) the transfer is in compliance with the terms of the applicable Award Agreement,
all applicable securities laws (including, without limitation, the Securities Act), and with the terms and conditions of this Section 8, (ii) the transfer does not cause the Company to become subject to the reporting requirements of the
Exchange Act, and (iii) the transferee consents in writing to be bound by the provisions of the Plan and the Award Agreement, including this Section 8. In connection with any proposed transfer, the Administrator may require the transferor
to provide at the transferor’s own expense an opinion of counsel to the transferor, satisfactory to the Administrator, that such transfer is in compliance with all foreign, federal and state securities laws (including, without limitation, the
Securities Act). Any attempted transfer of Shares not in accordance with the terms and conditions of this Section 8 shall be null and void, and the Company shall not reflect on its records any change in record ownership of any Shares as a
result of any such transfer, shall otherwise refuse to recognize any such transfer and shall not in any way give effect to any such transfer of Shares. The Company 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 any transfer not made in strict compliance with the provisions of this Section 8. Subject to the foregoing general provisions, and
unless otherwise provided in the applicable Award Agreement, Shares may be transferred pursuant to the following specific terms and conditions (provided that with respect to any transfer of Restricted Stock, all vesting and forfeiture provisions
shall continue to apply with respect to the original recipient): 
 (A) Transfers to Permitted Transferees. The Holder
may transfer any or all of the Shares to one or more Permitted Transferees; provided, however, that following such transfer, such Shares shall continue to be subject to the terms of this Plan (including this Section 8) and such Permitted
Transferee(s) shall, as a condition to any such transfer, deliver a written acknowledgment to that effect to the Company and shall deliver a stock power to the Company with respect to the Shares. Notwithstanding the foregoing, the Holder may not
transfer any Shares to a Person whom the Company reasonably determines is a direct competitor or a potential competitor of the Company or any of its Subsidiaries. 

  
 12 

 (B) Transfers Upon Death. Upon the death of the Holder, any Shares
then held by the Holder at the time of such death and any Shares acquired after the Holder’s death by the Holder’s legal representative shall be subject to the provisions of this Plan, and the Holder’s estate, executors,
administrators, personal representatives, heirs, legatees and distributees shall be obligated to convey such Shares to the Company or its assigns under the terms contemplated by the Plan and the Award Agreement. 

(b) Right of First Refusal. In the event that a Holder desires at any time to sell or otherwise transfer all or any part of his or her
Shares (other than shares of Restricted Stock which by their terms are not transferrable), the Holder first shall give written notice to the Company of the Holder’s intention to make such transfer. Such notice shall state the number of Shares
that the Holder proposes to sell (the “Offered Shares”), the price and the terms at which the proposed sale is to be made and the name and address of the proposed transferee. At any time within 30 days after the receipt of such
notice by the Company, the Company or its assigns may elect to purchase all or any portion of the Offered Shares at the price and on the terms offered by the proposed transferee and specified in the notice. The Company or its assigns shall exercise
this right by mailing or delivering written notice to the Holder within the foregoing 30-day period. If the Company or its assigns elect to exercise its purchase rights under this Section 8(b), the
closing for such purchase shall, in any event, take place within 45 days after the receipt by the Company of the initial notice from the Holder. In the event that the Company or its assigns do not elect to exercise such purchase right, or in the
event that the Company or its assigns do not pay the full purchase price within such 45-day period, the Holder shall be required to pay a transaction processing fee of $10,000 to the Company (unless waived by
the Administrator) and then may, within 60 days thereafter, sell the Offered Shares to the proposed transferee and at the same price and on the same terms as specified in the Holder’s notice. Any Shares not sold to the proposed transferee shall
remain subject to the Plan. If the Holder is a party to any stockholders agreements or other agreements with the Company and/or certain other of the Company’s stockholders relating to the Shares, (i) the transferring Holder shall comply
with the requirements of such stockholder agreements or other agreements relating to any proposed transfer of the Offered Shares, and (ii) any proposed transferee that purchases Offered Shares shall enter into such stockholder agreements or
other agreements with the Company and/or certain of the Company’s stockholders relating to the Offered Shares on the same terms and in the same capacity as the transferring Holder. 

(c) Company’s Right of Repurchase. 

(i) Right of Repurchase for Unvested Shares Issued Upon the Exercise of an Option. Upon a Termination Event, the Company or its assigns
shall have the right and option to repurchase from a Holder of Shares acquired upon exercise of a Stock Option which are still subject to a risk of forfeiture as of the Termination Event. Such repurchase rights may be exercised by the Company within
the later of (A) six months following the date of such Termination Event or (B) seven months after the acquisition of Shares upon exercise of a Stock Option. The repurchase price shall be equal to the lower of the original per share price
paid by the Holder, subject to adjustment as provided in Section 3(b) of the Plan, or the current Fair Market Value of such Shares as of the date the Company elects to exercise its repurchase rights. 

  
 13 

 (ii) Right of Repurchase With Respect to Restricted Stock. Upon a Termination Event,
the Company or its assigns shall have the right and option to repurchase from a Holder of Shares received pursuant to a Restricted Stock Award any Shares that are still subject to a risk of forfeiture as of the Termination Event. Such repurchase
right may be exercised by the Company within six months following the date of such Termination Event. The repurchase price shall be the lower of the original per share purchase price paid by the Holder, subject to adjustment as provided in
Section 3(b) of the Plan, or the current Fair Market Value of such Shares as of the date the Company elects to exercise its repurchase rights. 

(iii) Procedure. Any repurchase right of the Company shall be exercised by the Company or its assigns by giving the Holder written
notice on or before the last day of the repurchase period of its intention to exercise such repurchase right. Upon such notification, the Holder shall promptly surrender to the Company, free and clear of any liens or encumbrances, any certificates
representing the Shares being purchased, together with a duly executed stock power for the transfer of such Shares to the Company or the Company’s assignee or assignees. Upon the Company’s or its assignee’s receipt of the certificates
from the Holder, the Company or its assignee or assignees shall deliver to him, her or them a check for the applicable repurchase price; provided, however, that the Company may pay the repurchase price by offsetting and canceling any
indebtedness then owed by the Holder to the Company. 
 (d) Lockup Provision. If requested by the Company (or any successor of the
Company), a Holder shall not sell or otherwise transfer or dispose of (including, without limitation, pursuant to Rule 144 under the Securities Act) any Shares (or any securities into which the Shares converted) held by him or her for such period
following the effective date of a public offering by the Company or its successor of Shares (or any securities into which the Shares converted) as the Company or its successor shall specify reasonably and in good faith. If requested by the
underwriter engaged by the Company or its successor, each Holder shall execute a separate letter confirming his or her agreement to comply with this Section. 

(e) Adjustments for Changes in Capital Structure. If, as a result of any reorganization, recapitalization, reclassification, dividend,
stock split, reverse stock split or other similar change in the Common Stock, the outstanding Shares are increased or decreased or are exchanged for a different number or kind of securities of the Company, the restrictions contained in this
Section 8 shall apply with equal force to additional and/or substitute securities, if any, received by Holder in exchange for, or by virtue of his or her ownership of, Shares. 

(f) Termination. The terms and provisions of Section 8(b) and 8(c) (except for the Company’s right to repurchase Shares still
subject to a risk of forfeiture upon a Termination Event) shall terminate upon the closing of the IPO or upon consummation of any Sale Event or other transaction, in either case as a result of which Shares (or any other equity securities of the
Company or any successor of the Company) are registered under Section 12 of the Exchange Act and publicly-traded on any national security exchange. 

  
 14 

 SECTION 9. TAX WITHHOLDING 

(a) Payment by Grantee. Each grantee shall, no later than the date as of which the value of an Award or of any Shares or other amounts
received thereunder first becomes includable in the gross income of the grantee for income tax purposes, pay to the Company, or make arrangements satisfactory to the Administrator regarding payment of, any Federal, state, or local taxes of any kind
required by law to be withheld by the Company with respect to such income. The Company and any Subsidiary shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee. The
Company’s obligation to deliver stock certificates (or evidence of book entry) to any grantee is subject to and conditioned on any such tax withholding obligations being satisfied by the grantee. 

(b) Payment in Stock. Subject to prior approval by the Administrator, the Company’s required tax withholding obligation may be
satisfied, in whole or in part, by the Company withholding from Shares to be issued pursuant to an Award a number of Shares having an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount
due. 
 SECTION 10. SECTION 409A AWARDS.  

To the extent that any Award is determined to constitute “nonqualified deferred compensation” within the meaning of
Section 409A (a “409A Award”), the Award shall be subject to such additional rules and requirements as may be specified by the Administrator from time to time. In this regard, if any amount under a 409A Award is payable upon a
“separation from service” (within the meaning of Section 409A) to a grantee who is considered a “specified employee” (within the meaning of Section 409A), then no such payment shall be made prior to the date that is the
earlier of (i) six months and one day after the grantee’s separation from service, or (ii) the grantee’s death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties
and/or additional tax imposed pursuant to Section 409A. The Company makes no representation or warranty and shall have no liability to any grantee under the Plan or any other Person with respect to any penalties or taxes under Section 409A
that are, or may be, imposed with respect to any Award. 
 SECTION 11. AMENDMENTS AND TERMINATION 

The Board may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for
the purpose of satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the consent of the Holder of the Award. The Administrator may exercise its discretion to
reduce the exercise price of outstanding Stock Options or effect repricing through cancellation of outstanding Stock Options and by granting such Holders new Awards in replacement of the cancelled Stock Options. To the extent determined by the
Administrator to be required, Plan amendments shall be subject to approval by the Company stockholders entitled to vote at a meeting of stockholders. Nothing in this Section 11 shall limit the Board’s or Administrator’s authority to
take any action permitted pursuant to Section 3(c). The Board reserves the right to amend the Plan and/or the terms of any outstanding Stock Options to the extent reasonably necessary to comply with the requirements of the exemption pursuant to
paragraph (f)(4) of Rule 12h-1 of the Exchange Act. 

  
 15 

 SECTION 12. STATUS OF PLAN 

With respect to the portion of any Award that has not been exercised and any payments in cash, Stock or other consideration not received by a
grantee, a grantee shall have no rights greater than those of a general creditor of the Company unless the Administrator shall otherwise expressly so determine in connection with any Award. 

SECTION 13. GENERAL PROVISIONS 
 (a)
No Distribution; Compliance with Legal Requirements. The Administrator may require each person acquiring Shares pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the Shares without a view
to distribution thereof. No Shares shall be issued pursuant to an Award until all applicable securities law and other legal and stock exchange or similar requirements have been satisfied. The Administrator may require the placing of such stop-orders
and restrictive legends on certificates for Stock and Awards as it deems appropriate. 
 (b) Reserved. 

(c) Delivery of Stock Certificates. Stock certificates to grantees under the Plan shall be deemed delivered for all purposes when the
Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company; provided that stock certificates to be held
in escrow pursuant to Section 9 of the Plan shall be deemed delivered when the Company shall have recorded the issuance in its records. Uncertificated Stock shall be deemed delivered for all purposes when the Company or a stock transfer agent
of the Company shall have given to the grantee by electronic mail (with proof of receipt) or by United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company, notice of issuance and recorded the
issuance in its records (which may include electronic “book entry” records). 
 (d) No Employment Rights. The
adoption of the Plan and the grant of Awards do not confer upon any Person any right to continued employment or Service Relationship with the Company or any Subsidiary. 

(e) Trading Policy Restrictions. Option exercises and other Awards under the Plan shall be subject to the Company’s insider
trading policy-related restrictions, terms and conditions as may be established by the Administrator, or in accordance with policies set by the Administrator, from time to time. 

(f) Designation of Beneficiary. Each grantee to whom an Award has been made under the Plan may designate a beneficiary or beneficiaries
to exercise any Award on or after the grantee’s death or receive any payment under any Award payable on or after the grantee’s death. Any such designation shall be on a form provided for that purpose by the Administrator and shall not be
effective until received by the Administrator. If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the grantee’s estate. 

  
 16 

 (g) Legend. Any certificate(s) representing the Shares shall carry substantially the
following legend (and with respect to uncertificated Stock, the book entries evidencing such shares shall contain the following notation): 

The transferability of this certificate and the shares of stock represented hereby are subject to the restrictions, terms and conditions
(including repurchase and restrictions against transfers) contained in the Yumanity Therapeutics, Inc. Amended and Restated 2018 Stock Option and Grant Plan and any agreements entered into thereunder by and between the company and the holder
of this certificate (a copy of which is available at the offices of the company for examination). 
 (h) Information to Holders of
Options. In the event the Company is relying on the exemption from the registration requirements of Section 12(g) of the Exchange Act contained in paragraph (f)(1) of Rule 12h-1 of the Exchange Act,
the Company shall provide the information described in Rule 701(e)(3), (4) and (5) of the Securities Act to all Holders of Options in accordance with the requirements thereunder. The foregoing notwithstanding, the Company shall not be required
to provide such information unless the optionholder has agreed in writing, on a form prescribed by the Company, to keep such information confidential. 

SECTION 14. EFFECTIVE DATE OF PLAN 
 This
Plan amends and restates that certain Yumanity Holdings, LLC 2018 Unit Option and Grant Plan (the “Original Plan”), which was adopted by Yumanity Holdings, LLC on December 5, 2018 and approved by the members of Yumanity
Holdings, LLC on December 5, 2018. This Plan shall become effective upon the Company’s assumption of the Original Plan in connection with that certain merger between the Company and Yumanity Holdings, LLC following stockholder
approval in accordance with applicable state law and the Company’s certificate of incorporation and bylaws. No grants of Stock Options and other Awards may be made hereunder after December 5, 2028. 

SECTION 15. GOVERNING LAW 
 This Plan,
all Awards and any controversy arising out of or relating to this Plan and all Awards shall be governed by and construed in accordance with the General Corporation Law of the State of Delaware as to matters within the scope thereof, and as to all
other matters shall be governed by and construed in accordance with the internal laws of the Commonwealth of Massachusetts without regard to conflict of law principles that would result in the application of any law other than the law of the
Commonwealth of Massachusetts.

personally to the jurisdiction of the above named courts, that its property is exempt or immune from attachment or execution (except as protected by applicable law), that the suit, action or proceeding is brought in an inconvenient forum, that the
venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court, and (iii) hereby waives and agrees not to seek any review by any court of any other jurisdiction

Optionee, each party to the Agreement and any other holder of Shares issued pursuant to this Agreement (each, a “Party”) covenants and agrees that such party will participate in the arbitration in good faith. This Section 7 applies
equally to requests for temporary, preliminary or permanent injunctive relief, except that in the case of temporary or preliminary injunctive relief any party may proceed in court without prior arbitration for the limited purpose of avoiding
immediate and irreparable harm. 
 (d) Each Party (i) hereby irrevocably submits to the jurisdiction of any United States District
Court of competent jurisdiction for the purpose of enforcing the award or decision in any such proceeding, (ii) hereby waives, and agrees not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any
claim that it is not subject personally to the jurisdiction of the above named courts, that its property is exempt or immune from attachment or execution (except as protected by applicable law), that the suit, action or proceeding is brought in an
inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court, and (iii) hereby waives and agrees not to seek any review by any court
of any other jurisdiction which may be called upon to grant an enforcement of the judgment of any such court. Each Party hereby consents to service of process by registered mail at the address to which notices are to be given. Each Party agrees that
its, his or her submission to jurisdiction and its, his or her consent to service of process by mail is made for the express benefit of each other Party. Final judgment against any Party in any such action, suit or proceeding may be enforced in

6. Dispute Resolution. 

(a) Except as provided below, any dispute arising out of or relating to the Plan or the Shares, this Agreement, or the breach, termination or

right, and the arbitrator may in his or her discretion allow additional depositions upon good cause shown by the moving party. However, the arbitrator shall not have the power to order the answering of interrogatories or the response to requests for
admission. In connection with any arbitration, each party to the arbitration shall provide to the other, no later than seven business days before the date of the arbitration, the identity of all persons that may testify at the arbitration and a copy
of all documents that may be introduced at the arbitration or considered or used by a party’s witness or expert. The arbitrator’s decision and award shall be made and delivered within six months of the selection of the arbitrator. The
arbitrator’s decision shall set forth a reasoned basis for any award of damages or finding of liability. The arbitrator shall not have power to award damages in excess of actual compensatory damages and shall not multiply actual damages or
award punitive damages, and each party hereby irrevocably waives any claim to such damages. 
 (c) The Company, the Grantee, each party to
the Agreement and any other holder of Shares issued pursuant to this Agreement (each, a “Party”) covenants and agrees that such party will participate in the arbitration in good faith. This Section 6 applies equally to requests for
temporary, preliminary or permanent injunctive relief, except that in the case of temporary or preliminary injunctive relief any party may proceed in court without prior arbitration for the limited purpose of avoiding immediate and irreparable harm.

 (d) Each Party (i) hereby irrevocably submits to the jurisdiction of any United States District Court of competent jurisdiction for
the purpose of enforcing the award or decision in any such proceeding, (ii) hereby waives, and agrees not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject
personally to the jurisdiction of the above named courts, that its property is exempt or immune from attachment or execution (except as protected by applicable law), that the suit, action or proceeding is brought in an inconvenient forum, that the
venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court, and (iii) hereby waives and agrees not to seek any review by any court of any other

 
jurisdiction which may be called upon to grant an enforcement of the judgment of any such court. Each Party hereby consents to service of process by registered mail at the address to which
notices are to be given. Each Party agrees that its, his or her submission to jurisdiction and its, his or her consent to service of process by mail is made for the express benefit of each other Party. Final judgment against any Party in any such
action, suit or proceeding may be enforced in other jurisdictions by suit, action or proceeding on the judgment, or in any other manner provided by or pursuant to the laws of such other jurisdiction.

 YUMANITY HOLDINGS, LLC 

COMMON UNIT WARRANT 

Original Issue Date: August 14, 2015 

Void After: 5 PM Pacific Time on August 14, 2025 

This Warrant Is Issued to 
 SUSAN
LINDQUIST 
 (hereinafter called the “Holder,” which term shall include the Holder’s permitted assigns) by Yumanity Holdings, LLC, a
Delaware limited liability company (hereinafter referred to as the “Company”). This Common Unit Warrant (“Warrant”) may be transferred by the Holder only in accordance with the provisions of Section 11. 

This Warrant is being issued as one of a series of warrants (collectively, the “Warrants”) pursuant to the terms of the Bridge Unit and
Bridge Warrant Purchase Agreement, dated as of August 14, 2015, by and among the Company and the purchasers a party thereto, as amended, restated and/or otherwise modified from time to time, and a series of Exchange Agreements, each dated as of
August 14, 2015, by and among the Company and the other parties thereto, as amended, restated and/or otherwise modified from time to time. Capitalized terms not otherwise defined herein shall have the meaning given to such terms in the
Amended and Restated Operating Agreement of the Company, as amended, restated and/or otherwise modified from time to time (the “Operating Agreement”). 

The Company hereby certifies that, for value received, the Holder is entitled, subject to the terms and conditions set forth in this Warrant, to purchase from
the Company by exercising this Warrant, at any time on or after the closing of the Qualified Financing and in any event not after the Expiration Time, up to that number of Common Units equal to (i) 193,588 divided by (ii) the lowest per share
price at which each Qualified Financing Security (as defined in the Operating Agreement) is sold for cash in the next Qualified Financing, at an initial purchase price per Common Unit equal to the Bridge Conversion Price. The number of Common Units
and the purchase price thereof shall be adjusted or readjusted from time to time as provided in this Warrant (as so adjusted, the “Warrant Units” and the “Exercise Price”, respectively).“Expiration
Time” means 5pm Boston time on the tenth anniversary of the Effective Date. 

  
 1 

 1. Exercise of Warrant. The Holder may exercise this Warrant, in whole or in part
(except as to a fractional Common Unit), during the period beginning on the closing of the Qualified Financing and ending at the Expiration Time, by (i) delivering a subscription agreement, in the form attached hereto as
Exhibit A (the “Subscription Form”), duly executed by the Holder, specifying the number of Warrant Units to be issued to the Holder as a result of such exercise, (ii) surrendering this Warrant to the
Company, properly endorsed by the Holder (or if this Warrant has been destroyed, stolen or has otherwise been misplaced, by delivering to the Company an affidavit of loss duly executed by the Holder), and (iii) tendering payment for the Common
Units designated by the Subscription Form in lawful money of the United States in the form of cash, bank or certified check made payable to the order of the Company, or by wire transfer of immediately available funds, or in any combination thereof,
of the applicable Exercise Price as to which this Warrant is being exercised. 
 2. Net Exchange. The Holder may, in lieu of
exercising this Warrant pursuant to the terms of Section 1, elect to exchange this Warrant at any time beginning on the closing of the Qualified Financing and ending at the Expiration Time by delivering to the Company a written notice, in the
form attached hereto as Exhibit B (the “Exchange Notice”), duly executed by the Holder, specifying the number of Warrant Units it, he or she is requesting to be issued to the Holder as a result of such
exchange. The Holder shall thereupon be entitled to receive the number of Warrant Units equal to the product of (i) the number of Warrant Units issuable upon exercise of this Warrant (or, if only a portion of this Warrant is being exercised,
issuable upon the exercise of such portion) for cash, and (ii) a fraction, the numerator of which is the Fair Market Value at the time of such exercise minus the Exercise Price in effect at the time of such exercise, and the denominator
of which is the Fair Market Value at the time of such exercise, such number of Common Units so issuable upon such exchange to be rounded down to the nearest whole number of Common Units with any excess to be forfeited by the Holder. For all purposes
of this Warrant (other than Section 1 and this Section 2), any reference herein to the “exercise” of this Warrant shall be deemed to include a reference to the exchange of this Warrant for Common Units in accordance with the
terms of this Section 2. For purposes of this Section 2, “Fair Market Value” shall mean the price per Common Unit as determined in good faith by the Board of Directors or, if traded on a nationally recognized securities
exchange, the value shall be deemed to be the closing price of the security on such exchange or market on the date of exercise. 
 3.
Adjustment for Dividends, Distributions, Subdivisions, Combinations, Mergers, Consolidations or Sale of Assets. 
 3.1 Manner of
Adjustment. 
 (a) Unit Dividends, Distributions or Subdivisions. In the event the Company shall issue units in a unit dividend,
unit distribution or subdivision in respect of its Common Units, the Exercise Price in effect immediately before such unit dividend, unit distribution or subdivision shall, concurrently with the effectiveness of such unit dividend, unit distribution
or subdivision, be proportionately decreased and the number of Warrant Units shall be proportionately increased. 
 (b) Combinations or
Consolidations. In the event the outstanding Common Units shall be combined or consolidated, by reclassification or otherwise, into a lesser number of Common Units, the Exercise Price in effect immediately prior to such combination or
consolidation shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased and the number of Warrant Units shall be proportionately decreased. 

  
 2 

 (c) Adjustment for Reclassification, Exchange or Substitution. In the event that the
class of securities issuable upon the exercise of this Warrant shall be changed into the same or a different number of units (or other equity interests) of any class or classes of units (or other equity interests) of the Company or Holdings prior to
the Expiration Time, whether by capital reorganization, reclassification or otherwise (other than any event addressed by Sections 3.1(a) or 3.1(b)), then and in each such event the Holder shall have the right thereafter to exercise this Warrant
for the kind and amount of units and/or other securities and property receivable upon such reorganization, reclassification, or other change, by holders of the number of units (or other equity interests) of the class of securities into which such
Warrant might have been exercisable for immediately prior to such reorganization, reclassification, or change, all subject to further adjustment as provided herein. For the avoidance of doubt, this Section 3.1(c) shall not apply to a Sale of
the Company. 
 (d) IPO. In connection with preparation for an IPO, upon request the Board of Directors, the Holder will take
appropriate steps to implement a reorganization of the Company which may include, as examples, contribution of this Warrant (or the Warrant Units) to Holdings on terms that preserve and reflect the substantive economic rights of this Warrant (or the
Warrant Units) (consistent with Section 10.08 of the Operating Agreement) and execution of a lock-up (consistent with Section 10.09 of the Operating Agreement). 

3.2 Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Exercise Price pursuant to this
Section 3, the Company at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to the Holder a certificate setting forth such adjustment or readjustment and showing in detail the
facts upon which such adjustment or readjustment is based. 
 3.3 Closing of Books. The Company shall at no time close its transfer
books against the transfer of any Warrant Units in any manner which interferes with the timely and proper issuance of such Warrant Units. 

4. Sale of the Company. In the event of a Sale of the Company (as defined in the Operating Agreement) either (i) Holder shall
exercise this Warrant pursuant to Section 1 and/or 2 and such exercise will be deemed effective immediately prior to and contingent upon the consummation of such Sale of the Company, or (ii) if Holder elects not to exercise the Warrant,
this Warrant will expire immediately prior to the consummation of such Acquisition. 
 5. Covenants of the Company. During the period
within which the rights represented by this Warrant may be exercised, the Company shall at all times have authorized for the purpose of issue upon exercise of the rights evidenced hereby, a sufficient number of units of the class of securities
issuable upon exercise of this Warrant to provide for the exercise of such rights; provided, that if at any time the number of units of authorized but unissued securities issuable upon the exercise of this Warrant shall not be sufficient to
effect the exercise of this Warrant, upon the request of the holders of at least a majority of the Warrant Units issuable pursuant to all the of the Warrants (the “Requisite Majority”), the Company will promptly take such company
action as shall be necessary to increase its authorized but unissued units of such class of securities issuable upon the exercise of this Warrant as shall be sufficient for such purpose, including, without limitation, preparing an amendment to the
Operating Agreement for the review and approval of the Board of Directors and submitting such amendment to requisite Company members for approval. All securities which may be issued upon the exercise of the rights represented by this Warrant shall,
upon issuance, be validly issued, fully paid and non-assessable and free from all taxes, liens and charges with respect to the issue thereof. Upon surrender for exercise, this Warrant shall be canceled and
shall not be reissued; provided, however, that upon the partial exercise hereof a substitute Warrant of like tenor and date representing the rights to subscribe for and purchase any such unexercised portion hereof shall be issued. 

  
 3 

 6. Voting Rights. This Warrant shall not entitle the Holder to any voting rights or
any other rights as a member of the Company but upon presentation of this Warrant with the Subscription Form or Exchange Notice duly executed and the tender of payment of the aggregate Exercise Price (if applicable) at the office of the Company
pursuant to the provisions of this Warrant, the Holder shall forthwith be deemed a member of the Company in respect of the securities for which the Holder has so subscribed and paid or exchanged, and shall in connection therewith execute any and all
documents required for the Holder to become a party to the Operating Agreement (if not already a party thereto). This Warrant and the Warrant Units, when issued, shall be subject in all respects (including with respect to transfer, voting, economic
rights and otherwise) to the provisions of the Operating Agreement applicable to this Warrant or the Warrant Units, as applicable. 
 7.
No Change Necessary. The form of this Warrant need not be changed because of any adjustment in the Exercise Price or in the number or type of Warrant Units. A Warrant issued after any adjustment or any partial exercise or upon replacement may
continue to express the same Exercise Price and the same number and type of Warrant Units (appropriately reduced in the case of partial exercise) as are stated on this Warrant as initially issued, and that Exercise Price and that number and type of
Warrant Units shall be considered to have been so changed as of the close of business on the date of adjustment. 
 8. Notices to
Holder. If at any time prior to the expiration of this Warrant and prior to its exercise, any of the following events shall occur: 

(a) the Company shall take a record of the holders of its Common Units for the purpose of entitling them to receive a dividend or distribution
payable in respect of the Common Units, other than Tax Distributions, or 
 (b) the consummation of a Sale of the Company 

then, in any one or more of said events, the Company shall give to the Holder written notice of such event. Such notice shall set forth the date on which such
event shall take place, shall if applicable specify the deadline date as of which the holders of Common Units of record shall be entitled or required to take any action, or the record date with respect to any dividend, and shall be given at least
ten (10) days’ prior to the deadline or record date. Failure to give such notice or any defect therein shall not affect the validity of any action taken in connection with the declaration or payment of any such dividend or the making of
any such distribution or any action in connection with any such proposed Sale of the Company, provided that any cancellation of this Warrant pursuant to Section 4 shall be contingent on delivery by the Company of the written notice(s) specified
in such Section. 
 9. Addresses for Notices. All notices, requests, consents and other communications hereunder shall be in writing,
either delivered in hand or mailed by registered or certified mail, return receipt requested, or sent by facsimile, and shall be deemed to have been duly made when delivered: 

(a) If to the Holder, to the Holder’s address as shown on the Holder’s signature page hereto; or 

(b) If to the Company, at the Company’s principal executive office, with attention to the President of the Company. 

  
 4 

 10. Substitution. In the case this Warrant shall be mutilated, lost, stolen or
destroyed, the Company shall issue a new Warrant of like tenor and denomination and deliver the same (a) in exchange and substitution for and upon surrender and cancellation of any mutilated Warrant, or (b) in lieu of any Warrant lost,
stolen or destroyed, upon receipt of evidence satisfactory to the Company of the loss, theft, or destruction of such Warrant (including, without limitation, a reasonably detailed affidavit with respect to the circumstances of any loss, theft or
destruction), and of indemnity (or, in the case of the initial Holder or any other institutional holder, an indemnity agreement) satisfactory to the Company. 

11. Transfer Restrictions. This Warrant shall be exercisable only by the Holder. Without the prior written consent of the Company, this
Warrant shall not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process. Any attempted transfer, assignment, pledge, hypothecation
or other disposition of this Warrant or of any rights granted hereunder contrary to the provisions of this Section 11, or the levy of any attachment or similar process upon this Warrant or such rights, shall be null and void. Notwithstanding
the foregoing, the Holder may transfer this Warrant in full to an Affiliate or family member (as defined in the Operating Agreement) of the Holder; provided that (1) the transferee shall agree in writing to be bound by and subject to all
the obligations and entitled to all the benefits of this Warrant as the “Holder” hereunder, and (2) the Company obtains prior assurances reasonably satisfactory to the Company that such transfer is exempt from the registration
requirements of, or is covered by an effective registration statement under, the Act and applicable state securities or “blue sky” laws, including, without limitation, receipt of an opinion to such effect of counsel reasonably satisfactory
to the Company. 
 12. Taxes. The Company makes no representation about tax treatment to the Holder with respect to receipt or
exercise of this Warrant or acquiring, holding or disposing of the Warrant Units, and the Holder represents that the Holder has had the opportunity to discuss such treatment with the Holder’s tax advisers. 

13. Remedies. Each party stipulates that the remedies at law in the event of any default or threatened default by the other party in
the performance or compliance with any of the terms of this Warrant are and shall not be adequate, and that such terms may be specifically enforced by a decree for that specific performance of any agreement contained herein or by an injunction
against a violation of any of the terms hereof or otherwise. 
 14. Governing Law. This Warrant shall be governed by, and construed
in accordance with the internal laws of the State of Delaware, without reference to principles of conflict of laws or choice of laws. 

  
 5 

 15. Amendment. Except as expressly provided herein, neither this Warrant nor any term
hereof may be amended, waived, discharged or terminated other than by a written instrument referencing this Warrant and signed by the Company and the holders of warrants representing not less than a majority of the Warrant Units issuable upon
exercise of any and all outstanding Warrants, which majority does not need to include the consent of the Holder; provided, however, that no such amendment, waiver or termination shall (i) increase the Exercise Price or
(ii) otherwise decrease the number of Warrant Units issuable hereunder. Any amendment, waiver, discharge or termination effected in accordance with this Section 15shall be binding upon each holder of the Warrants, each future holder of
such Warrants and the Company. 
 16. Miscellaneous. The invalidity or unenforceability of any provision hereof shall in no way
affect the validity or enforceability of any other provision. This Warrant may be executed in any number of counterparts, each of which shall be deemed an original, but all of which taken together shall constitute one and the same instrument, and
any of the parties hereto may execute this Warrant by signing any such counterpart. This Warrant may be executed and delivered by facsimile, or by e-mail in portable document format (.pdf) and delivery of the
signature page by such method will be deemed to have the same effect as if the original signature had been delivered to the other parties.

the purchase of the Units, (2) it has had the opportunity to ask questions concerning the Units and the Company and all questions posed have been answered by the Company to its satisfaction, (3) it has been given the opportunity to obtain

registration statement under the Act and applicable state securities laws covering any such transaction involving the Units, (2) the Company receives an opinion of legal counsel to the undersigned (concurred in by legal counsel for the Company)
stating that such transaction is exempt from registration or the Company otherwise satisfies itself that such transaction is exempt from registration, and (3) the sale or distribution is in compliance with the Operating Agreement.
