	Where:				X = the number of shares of the Class to be issued to the Warrantholder.
			
					Y = the number of shares of the Class requested to be exercised under this Agreement.
			
					A = the fair market value of one (1) share of the Class at the time of issuance of such shares of the Class.
			
			B =		the Exercise Price.

 For purposes of the above calculation, current fair market value of shares of the Class shall mean with
respect to each share of the Class:

the time of such exercise; 
 (ii) if the exercise is after, and not in connection with an Initial Public Offering, and: 

(A) if the Common Stock is traded on a securities exchange, the fair market value shall be deemed to be the product of
(x) the average of the closing prices over a five (5) day period ending three days before the day the current fair market value of the securities is being determined and (y) (i) 1, or (ii) if the Class is a series of
convertible preferred stock, the number of shares of Common Stock into which each share of the Class is convertible at the time of such exercise; or 

(B) if the Common Stock is traded over-the-counter, the fair market value shall be deemed to be the product of (x) the
average of the closing bid and asked prices quoted on the NASDAQ system (or similar system) over the five (5) day period ending three days before the day the current fair market value of the securities is being determined and
(y) (i) 1, or (ii) if the Class is a series of convertible preferred stock, the number of shares of Common Stock into which each share of the Class is convertible at the time of such exercise; 

(iii) if at any time the Common Stock is not listed on any securities exchange or quoted in the NASDAQ National Market or the
over-the-counter market, the current fair market value of a share of the Class shall be the product of (x) the highest price per share which the Company could obtain from a willing buyer (not a current employee or director) for shares of Common
Stock sold by the Company, from authorized but unissued shares, as determined in good faith by its Board of Directors and (y) (i) 1, or (ii)

  
 4 








 
if the Class is a series of convertible preferred stock, the number of shares of Common Stock into which each share of the Class is convertible at the time of such exercise, unless the Company
shall become subject to a Merger Event, in which case the fair market value of a share of the Class shall be deemed to be the per share value received by the holders of the outstanding shares of the Class on a common equivalent basis pursuant to
such Merger Event. 
 Upon partial exercise by either cash or Net Issuance, the Company shall promptly issue an amended Agreement
representing the remaining number of shares purchasable hereunder. All other terms and conditions of such amended Agreement shall be identical to those contained herein, including, but not limited to the Effective Date hereof. 

(b) Exercise Prior to Expiration. To the extent this Agreement is not previously exercised as to all shares subject hereto, and if the
fair market value of one share of the Class is greater than the Exercise Price then in effect, this Agreement shall be deemed automatically exercised pursuant to Section 3(a) (even if not surrendered) immediately before its expiration. For
purposes of such automatic exercise, the fair market value of one share of the Class upon such expiration shall be determined pursuant to Section 3(a). To the extent this Agreement or any portion thereof is deemed automatically exercised
pursuant to this Section 3(b), the Company agrees to promptly notify the Warrantholder of the number of shares of the Class if any, the Warrantholder is to receive by reason of such automatic exercise. 

SECTION 4. RESERVATION OF SHARES. 

During the term of this Agreement, the Company will at all times have authorized and reserved a sufficient number of shares of the Class to
provide for the exercise of the rights to purchase shares as provided for herein, and shall have authorized and reserved a sufficient number of shares of its Common Stock to provide for the conversion of the shares of the Class (if the Class is a
series of convertible preferred stock) available hereunder. 
 SECTION 5. NO FRACTIONAL SHARES OR SCRIP. 

No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Agreement, but in lieu of such
fractional shares the Company shall make a cash payment therefor upon the basis of the Exercise Price then in effect. 
 SECTION
6. NO RIGHTS AS SHAREHOLDER/STOCKHOLDER. 
 This Agreement does not entitle the Warrantholder to any voting rights or other rights
as a shareholder/stockholder of the Company prior to the exercise of this Agreement. 
 SECTION 7. WARRANTHOLDER REGISTRY.

 The Company shall maintain a registry showing the name and address of the registered holder of this Agreement. Warrantholder’s

 SECTION 8. ADJUSTMENT RIGHTS. 

The Exercise Price and the number of shares of the Class purchasable hereunder are subject to adjustment, as follows: 

(a) Merger Event. If at any time there shall be Merger Event, then, as a part of such Merger Event, lawful provision shall be made so
that the Warrantholder shall thereafter be entitled to receive, upon exercise of this Agreement, the number of shares or other securities or property of the surviving or successor entity resulting from such Merger Event that would have been issuable
if Warrantholder had exercised this Agreement in full immediately prior to the Merger Event. In any such case, appropriate adjustment (as determined in good faith by the Company’s Board of Directors) shall be made in the application of the
provisions of this Agreement with respect to the rights and interests of the Warrantholder after the Merger Event to the end that the provisions of this Agreement (including adjustments of the Exercise Price and number of shares of the Class
purchasable) shall be applicable in their entirety, and to the greatest extent possible. Without limiting the foregoing, (i) this Warrant shall terminate upon the closing of a Liquid Sale to the extent not previously exercised, and (ii) in
connection with a Merger Event that is not a Liquid Sale, the Company shall cause the successor or surviving entity to assume this Warrant and the obligations of the Company hereunder on the closing thereof, and thereafter this Warrant shall be
exercisable for the same number and type of securities or other property as the Warrantholder would have received in consideration for the shares of the Class issuable hereunder had it exercised this Warrant in full as of immediately prior to such
closing, at an aggregate Exercise Price no greater than the aggregate Exercise Price in effect as of immediately prior to such closing, and subject to further adjustment from time to time in accordance with the provisions of this Warrant. In
connection with a Merger Event and upon Warrantholder’s written election to the Company, the Company shall cause this Warrant Agreement to be exchanged for the consideration that Warrantholder would have received if Warrantholder chose to
exercise its right to have shares issued pursuant to the Net Issuance provisions of this Warrant Agreement without actually exercising such right, acquiring such shares and exchanging such shares for such consideration. 

(b) Reclassification of Shares. Except as set forth in Section 8(a), if the Company at any time shall, by combination,
reclassification, exchange or subdivision of securities or otherwise, change the outstanding shares of the Class into the same or a different number of securities of any other class/series or classes/series, this Agreement shall thereafter represent
the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities which were subject to the purchase rights under this Agreement immediately prior to such combination,
reclassification, exchange, subdivision or other change. 
 (c) Subdivision or Combination of Shares. If the Company at any time
shall combine or subdivide it’s the outstanding shares of the Class, (i) in the case of a subdivision, the Exercise Price shall be proportionately decreased, and the number of shares of the Class issuable upon exercise of this Agreement
shall be proportionately increased, or (ii) in the case of a combination, the Exercise Price shall be proportionately increased, and the number of shares of the Class issuable upon the exercise of this Agreement shall be proportionately
decreased. 

  
 6 








 (d) Stock Dividends. If the Company at any time while this Agreement is outstanding and
unexpired shall: 
 (i) pay a dividend with respect to the outstanding shares of the Class payable in shares of the Class,
then the Exercise Price shall be adjusted, from and after the date of determination of stockholders entitled to receive such dividend or distribution, to that price determined by multiplying the Exercise Price in effect immediately prior to such
date of determination by a fraction (A) the numerator of which shall be the total number of shares of the Class outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of
shares of the Class outstanding immediately after such dividend or distribution; or 
 (ii) make any other distribution with
respect to the shares of the Class (or stock into which the shares of the Class are convertible), except any distribution specifically provided for in any other clause of this Section 8, then, in each such case, provision shall be made by the
Company such that the Warrantholder shall receive upon exercise or conversion of this Warrant a proportionate share of any such distribution as though it were the holder of the shares of the Class (or other stock for which the shares of the Class
are convertible) as of the record date fixed for the determination of the stockholders of the Company entitled to receive such distribution. 

(e) Antidilution Rights. At all times (if any) where the Class is a series of convertible preferred stock, additional antidilution
rights applicable to the shares of such Class purchasable hereunder are as set forth in the Company’s Charter and shall be applicable with respect to the shares issuable hereunder. The Company shall promptly provide the Warrantholder with any
restatement, amendment, modification or waiver of any provision of the Charter applicable to the Class; provided, that no such amendment, modification or waiver shall impair or reduce the antidilution rights applicable to the Class unless such
amendment, modification or waiver affects the rights of Warrantholder with respect to the shares of the Class purchasable hereunder in the same manner as it affects all outstanding shares of the Class For the avoidance of doubt, there shall be no
duplicate anti-dilution adjustment pursuant to this subsection (e), the forgoing subsection (d) and the Company’s Charter. 
 (f)
Notice of Adjustments. If: (i) the Company shall declare any dividend or distribution upon the outstanding shares of the Class, whether in stock, cash, property or other securities; (ii) the Company shall offer for subscription pro
rata to the holders of the outstanding shares of the Class any additional shares of stock of any class or other rights; (iii) there shall be any Merger Event; (iv) there shall be an Initial Public Offering; or (v) there shall be any
voluntary dissolution, liquidation or winding up of the Company; then, in connection with each such event, the Company shall send to the Warrantholder: (A) at least twenty (20) days’ prior written notice of the date on which the books
of the Company shall close or a record shall be taken for such dividend, distribution, subscription rights (specifying the date on which the holders of shares of the Class shall be entitled thereto) or for determining rights to vote in respect of
such Merger Event, dissolution, liquidation or winding up; (B) .in the case of any such Merger Event, dissolution, liquidation or winding up, at least twenty (20) days’ prior written notice of the date when the same shall take place

property deliverable upon such Merger Event, dissolution, liquidation or winding up); and (C) in the case of an Initial Public Offering, the Company shall give the Warrantholder at least
twenty (20) days’ written notice prior to the effective date thereof. 
 Each such written notice shall set forth, in reasonable
detail, (i) the event requiring the notice, and (ii) if any adjustment is required to be made, (A) the amount of such adjustment, (B) the method by which such adjustment was calculated, (C) the adjusted Exercise Price (if
the Exercise Price has been adjusted), and (D) the number of shares subject to purchase hereunder after giving effect to such adjustment, and shall be given by first class mail, postage prepaid, or by reputable overnight courier with all
charges prepaid, addressed to the Warrantholder at the address for Warrantholder set forth in the registry referred to in Section 7. 

(g) Timely Notice. Failure to timely provide such notice required by subsection (f) above shall entitle Warrantholder to retain
the benefit of the applicable notice period notwithstanding anything to the contrary contained in any insufficient notice received by Warrantholder.

where damages will not be readily ascertainable. The Company expressly agrees that, if the Company breaches this Agreement, it shall not oppose an application by the Warrantholder or any other person entitled to the benefit of this Agreement
requiring specific performance of any or all provisions hereof or enjoining the Company from continuing to commit any such breach of this Agreement. 

(c) No Impairment of Rights. The Company will not, by amendment of its Charter or through any other means, avoid or seek to avoid the
observance or performance of any of the terms of this Agreement, but will at all times in good faith assist in the carrying out of all such terms. 

(d) Attorney’s Fees. In any litigation, arbitration or court proceeding between the Company and the Warrantholder relating hereto,
the prevailing party shall be entitled to attorneys’ fees and expenses and all costs of proceedings incurred in enforcing this Agreement. For the purposes of this Section 12(d), attorneys’ fees shall include without limitation fees
incurred in connection with the following: (i) contempt proceedings; (ii) discovery; (iii) any motion, proceeding or other activity of any kind in connection with an insolvency proceeding; (iv) garnishment, levy, and debtor and
third party examinations; and (v) post-judgment motions and proceedings of any kind, including without limitation any activity taken to collect or enforce any judgment. 

(e) Severability. In the event any one or more of the provisions of this Agreement shall for any reason be held invalid, illegal or
unenforceable, the remaining provisions of this Agreement shall be unimpaired, and the invalid, illegal or unenforceable provision shall be replaced by a mutually acceptable valid, legal and enforceable provision, which comes closest to the
intention of the parties underlying the invalid, illegal or unenforceable provision.

 (h) Headings. The various headings in this Agreement are inserted for convenience only and
shall not affect the meaning or interpretation of this Agreement or any provisions hereof. 
 (i) Advice of Counsel. Each of the
parties represents to each other party hereto that it has discussed (or had an opportunity to discuss) with its counsel this Agreement and, specifically, the provisions of Sections 12(n), 12(o), 12(p), 12(q) and 12(r). 

(j) No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the
event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any provisions of this Agreement. 
 (k) No Waiver. No omission or delay by Warrantholder at any time to enforce any
right or remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by the Company at any time designated, shall be a waiver of any such right or remedy to which Warrantholder is entitled, nor shall it in
any way affect the right of Warrantholder to enforce such provisions thereafter. 
 (l) Survival. All agreements, representations and
warranties contained in this Agreement or in any document delivered pursuant hereto shall be for the benefit of Warrantholder and shall survive the execution and delivery of this Agreement and the expiration or other termination of this Agreement.

 (m) Governing Law. This Agreement have been negotiated and delivered to Warrantholder in the Commonwealth of Massachusetts, and
shall have been accepted by Warrantholder in the Commonwealth of Massachusetts. Delivery of shares of the Class to Warrantholder by the Company under this Agreement is due in the Commonwealth of Massachusetts. This Agreement shall be governed by,
and construed and enforced in accordance with, the laws of the Commonwealth of Massachusetts, excluding conflict of laws principles that would cause the application of laws of any other jurisdiction. 

(n) Consent to Jurisdiction and Venue. All judicial proceedings arising in or under or related to this Agreement may be brought in any
state or federal court of competent jurisdiction located in the Commonwealth of Massachusetts. By execution and delivery of this Agreement, each party hereto generally and unconditionally: (a) consents to personal jurisdiction in Suffolk
County, Commonwealth of Massachusetts; (b) waives any objection as to jurisdiction or venue in Suffolk County, Commonwealth of Massachusetts; (c) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid
courts; and (d) irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement. Service of process on any party hereto in any action arising out of or relating to this Agreement shall be effective if given in
accordance with the requirements for notice set forth in Section 12(f), and shall be deemed effective and received as set forth in Section 12(f). Nothing herein shall affect the right to serve process in any other manner permitted by law
or shall limit the right of either party to bring proceedings in the courts of any other jurisdiction. 

  
 14 








 (o) Mutual Waiver of Jury Trial. Because disputes arising in connection with complex
financial transactions are most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved
by a judge applying such applicable laws. EACH OF THE COMPANY AND WARRANTHOLDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY,
“CLAIMS”) ASSERTED BY THE COMPANY AGAINST WARRANTHOLDER OR ITS ASSIGNEE OR BY WARRANTHOLDER OR ITS ASSIGNEE AGAINST THE COMPANY. This waiver extends to all such Claims, including Claims that involve Persons other than the Company and the
Warrantholder; Claims that arise out of or are in any way connected to the relationship between the Company and Warrantholder; and any Claims for damages, breach of contract, specific performance, or any equitable or legal relief of any kind,
arising out of this Agreement. 
 (p) Arbitration. If the Mutual Waiver of Jury Trial set forth in Section 12(o) is ineffective
or unenforceable, the parties agree that all Claims shall be submitted to binding arbitration in accordance with the commercial arbitration rules of JAMS (the “Rules”), such arbitration to occur before one arbitrator, which arbitrator
shall be a retired California state judge or a retired Federal court judge. Such proceeding shall be conducted in San Francisco County, California, with California rules of evidence and discovery applicable to such arbitration. The decision of the
arbitrator shall be binding on the parties, and shall be final and nonappealable to the maximum extent permitted by law. Any judgment rendered by the arbitrator may be entered in a court of competent jurisdiction and enforced by the prevailing party
as a final judgment of such court. 
 (q) Prearbitration Relief. In the event Claims are to be resolved by arbitration, either party
may seek from a court of competent jurisdiction identified in Section 12(n), any prejudgment order, writ or other relief and have such prejudgment order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that
all Claims are otherwise subject to resolution by binding arbitration. 
 (r) Counterparts. This Agreement and any amendments,
waivers, consents or supplements hereto may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts shall
constitute but one and the same instrument. 
 (s) Specific Performance. The parties hereto hereby declare that it is impossible to
measure in money the damages which will accrue to Warrantholder by reason of the Company’s failure to perform any of the obligations under this Agreement and agree that the terms of this Agreement shall be specifically enforceable by
Warrrantholder. If Warrantholder institutes any action or proceeding to specifically enforce the provisions hereof, any person against whom such action or proceeding is brought hereby waives the claim or defense therein that Warrantholder has an
adequate remedy at law, and such person shall not offer in any such action or proceeding the claim or defense that such remedy at law exists.
