RECITALS
WHEREAS, Employee was employed by the Company;
WHEREAS, Employee signed an EMPLOYEE INVENTION ASSIGNMENT AND
CONFIDENTIALITY AGREEMENT with the Company on June 11, 2019 (the “Confidentiality Agreement”);
WHEREAS, the Company and Employee have entered into one or more Stock Option Agreement(s) granting Employee the option to purchase shares of the Company’s common stock subject to the terms and conditions of the Company’s 2008 Equity Incentive Plan, 2018 Equity Incentive Plan, and/or the 2021 Equity Incentive Plan (collectively, the “EIP”) and the associated Stock Option Agreement(s) and/or RSU Agreement(s) (collectively the “Equity Agreements”);
WHEREAS, Employee will cease employment with the Company effective June 30, 2022 (the “Separation Date”); and
WHEREAS, the Parties wish to resolve any and all disputes, claims, complaints, grievances, charges, actions, petitions, and demands that the Employee may have against the Company and any of the Releasees as defined below, including, but not limited to, any and all claims arising out of or in any way related to Employee’s employment with or separation from the Company; 
NOW, THEREFORE, in consideration of the mutual promises made herein, the Company and Employee hereby agree as follows:
1.Consideration.  In consideration for Employee entering into this Agreement and abiding by its terms and conditions, Company shall provide the following benefits to aid Employee’s employment transition: 
a.Bonus Payment.  The Company agrees to pay Employee a lump sum amount of one hundred forty-one thousand, six hundred sixty-six dollars and sixty-seven cents ($141,666.67), less applicable payroll deductions and withholdings.  This payment represents the pro-rated portion of Employee’s target bonus for FY23 based on his Separation Date.  This payment will be made to Employee within thirty (30) business days after the Effective Date of this Agreement.  
b.COBRA. Under COBRA and the Company’s current group health insurance policies, Employee will be eligible to continue health insurance benefits at Employee’s own expense (provided Employee is currently enrolled and timely elects COBRA) following the Separation Date pursuant to Section 2 below. Additionally, in connection with this Agreement, Company shall pay Employee’s COBRA premiums for up to one (1) year or until the date on which Employee obtains full coverage from another employer, whichever is earlier.
c.Stock Options. Your participation the Company’s EIP terminates on your Separation Date and all Options that are unvested as of such date will be forfeited and cancelled on the Separation Date. The Company agrees to extend the time allowed to exercise any vested Options you may have under the Equity Agreements to one (1) year, but in no event shall any vested Options be exercised later than the expiration date as set forth in the applicable Stock Option Agreement. You acknowledge that this extension is a modification of any Option that qualifies as an Incentive Stock Option (ISO), which will result in any such Option immediately becoming disqualified as an ISO and being treated for all purposes as a Nonqualified Stock Option. Capitalized terms in 

this paragraph not defined in this Agreement shall have the meanings ascribed to such terms in the applicable Equity Agreements.
d.Acknowledgement. Employee acknowledges that without this Agreement, Employee is otherwise not entitled to the consideration listed in this Section 1.
2.Benefits.  Employee’s participation in all benefits and incidents of employment, including, but not limited to, vesting in stock options and/or restricted stock units, and the accrual of bonuses, vacation, and paid time off, ceased as of the Separation Date.  Employee’s health insurance benefits shall cease on the last day of June, 2022, after which Employee may continue Employee’s health insurance under COBRA at Employee’s own expense provided Employee makes a timely election.  Employee will be provided with a separate notice of COBRA rights.  
3.Payment of Salary and Receipt of All Benefits.  Employee acknowledges and represents that, other than the consideration set forth in this Agreement, the Company has paid or provided all salary, wages, commissions, bonuses, accrued vacation/paid time off, premiums, leaves, housing allowances, relocation costs, interest, severance, outplacement costs, fees, reimbursable expenses, stock, stock options, vesting, and any and all other benefits and compensation due to Employee.  Employee further acknowledges and represents that Employee has received any leave to which Employee was entitled or which Employee has requested, if any, under the California Family Rights Act and/or the Family Medical Leave Act, and that Employee did not sustain any workplace injury during their employment with the Company. 
4.Release of Claims.  Employee agrees that the foregoing consideration represents settlement in full of all outstanding obligations owed to Employee by the Company and its current and former officers, directors, employees, agents, investors, attorneys, shareholders, administrators, affiliates, benefit plans, plan administrators, professional employer organization or co-employer, insurers, trustees, divisions, subsidiaries, predecessor and successor corporations and assigns (collectively, the “Releasees”).  Employee, on Employee’s own behalf and on behalf of Employee’s respective heirs, family members, executors, agents, and assigns, hereby and forever releases the Releasees from, and agrees not to sue concerning, or in any manner to institute, prosecute, or pursue, any claim, complaint, charge, duty, obligation, demand, or cause of action relating to any matters of any kind, whether presently known or unknown, suspected or unsuspected, that Employee may possess against any of the Releasees arising from any omissions, acts, facts, or damages that have occurred up until and including the Effective Date of this Agreement, including, without limitation:

c.     any and all claims relating to, or arising from, Employee’s right to purchase, or actual purchase of shares of stock of the Company, including, without limitation, any claims for fraud, misrepresentation, breach of fiduciary duty, breach of duty under applicable state corporate law, and securities fraud under any state or federal law;

5.Non-Interference With Legal Rights.  Nothing in this Agreement (i) limits or affects Employee’s right to challenge the validity of this Agreement under the Age Discrimination in Employment Act or the Older Worker Benefit Protection Act; (ii) prevents the filing of a charge or complaint with or the participation in an investigation or proceeding conducted by the Equal Employment Opportunity Commission (EEOC), the National Labor Relations Board (NLRB), the Securities and Exchange Commission (SEC), or any other federal, state or local agency charged with the enforcement of any laws, including providing documents or other information, or (iii) prevents the exercise of rights under Section 7 of the National Labor Relations Act to engage in protected, concerted activity with other employees.  By signing this Agreement, Employee is waiving their right to recover any individual relief (including  back pay, front pay, reinstatement or other legal or equitable relief) in any charge, complaint, or lawsuit or other proceeding brought by Employee or on Employee’s behalf by any third party or under (i), (ii), or (iii) of this Section, except for any right Employee may have to receive a payment from a government agency (and not the Company) for information provided to the government agency.

Employee further acknowledges that Employee has been advised by this writing that: (a) Employee should consult with an attorney prior to executing this Agreement; (b) Employee has twenty-one (21) days within which to consider this Agreement; (c) Employee has seven (7) days following Employee’s execution of this Agreement to revoke this Agreement; (d) this Agreement shall not be effective until after the revocation period has expired; and (e) nothing in this Agreement prevents or precludes Employee from challenging or seeking a determination in good faith of the validity of this waiver under the ADEA, nor does it impose any condition precedent, penalties, or costs for doing so, unless specifically authorized by federal law.  In the event Employee signs this Agreement and returns it to the Company in less than the 21-day period identified above, Employee hereby acknowledges that Employee has knowingly and voluntarily chosen to waive the time period allotted for considering this Agreement. Employee acknowledges and understands that revocation must be accomplished by a written notification to the person executing this Agreement on the Company’s behalf that is received prior to the Effective Date. The parties agree that changes, whether material or immaterial, do not restart the running of the 21-day period.
7.California Civil Code Section 1542.  Employee acknowledges that Employee has been advised to consult with legal counsel and is familiar with the provisions of California Civil Code Section 1542, a statute that otherwise prohibits the release of unknown claims, which provides as follows:
A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER 
3

MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR RELEASED PARTY.
Employee, being aware of said code section, agrees to expressly waive any rights Employee may have thereunder, as well as under any other statute or common law principles of similar effect.
8.No Pending or Future Lawsuits.  Employee represents that Employee has no lawsuits, claims, or actions pending in Employee’s name, or on behalf of any other person or entity, against the Company or any of the other Releasees. Employee also represents that Employee does not intend to bring any claims on Employee’s own behalf or on behalf of any other person or entity against the Company or any of the other Releasees.
9.Intentionally Blank.  
10.Trade Secrets and Confidential Information/Company Property.

Employee’s signature below constitutes Employee’s certification under penalty of perjury that Employee has returned all documents and other items provided to Employee by the Company (with the exception of a copy of the Employee Handbook and personnel documents specifically relating to Employee), developed or obtained by Employee in connection with Employee’s employment with the Company, or otherwise belonging to the Company. This includes, but is not limited to, laptops, power cords, external drives, monitors, computers, files, credit cards, identification badges, keys, notes, business plans and forecasts, financial information, customer information, product information, specifications, training material, and computer-recorded information.  
11.No Cooperation.  Subject to the Confidentiality section, Employee further agrees that Employee will not knowingly encourage, counsel, or assist any attorneys or their clients in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or complaints by any third party against any of the Releasees, unless under a subpoena or other court order to do so or upon written request from an administrative agency or the legislature or as related directly to the ADEA waiver in this Agreement. Employee agrees both to immediately notify the Company upon receipt of any such subpoena or court order or written request from an administrative agency or the legislature, and to furnish, within three (3) business days of its receipt, a copy of such subpoena or other court order or written request from an administrative agency or the legislature.  If approached by anyone for counsel or assistance in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or complaints against any of the Releasees, Employee shall state no more than that Employee cannot provide counsel or assistance.
12.Non-Disparagement.  Subject to the Confidentiality section, Employee agrees to refrain from any disparagement, defamation, libel, or slander of any of the Releasees, and agrees to refrain from any tortious interference with the contracts and relationships of any of the Releasees.  Employee shall direct any inquiries by potential future employers to the Company’s human resources department.
13.Breach.  In addition to the rights provided in the “Attorneys’ Fees” section below, Employee acknowledges and agrees that any material breach of this Agreement, unless such breach constitutes a legal action by Employee challenging or seeking a determination in good faith of the validity of the waiver herein under the ADEA, or of any provision of the Confidentiality Agreement shall entitle the Company immediately to recover and/or cease providing the consideration provided to Employee under this Agreement, and to obtain damages, except as provided by law, except for $100 which shall be adequate and sufficient consideration to support Employee’s obligations under this Agreement.  Except as provided by law, Employee shall also be responsible to the Company for all costs, attorneys’ fees, and any and all damages incurred by the Company in enforcing Employee’s obligations under this Agreement or the Confidentiality Agreement, including the bringing of any action to recover the consideration. 
14.No Admission of Liability.  Employee understands and acknowledges that with respect to all claims released herein, this Agreement constitutes a compromise and settlement of any and all actual or potential disputed claims by Employee, unless such claims were explicitly not released by the release in this Agreement.  No action taken by the Company hereto, either previously or in connection with this Agreement, shall be deemed or construed to be (a) an admission of the truth or falsity of any actual or potential claims or (b) an acknowledgment or admission by the Company of any fault or liability whatsoever to Employee or to any third party.

15.Non-Solicitation.  Employee agrees that for a period of twelve (12) months immediately following the Effective Date of this Agreement, Employee shall not directly or indirectly solicit any of the Company’s employees to leave their employment at the Company.
16.Costs.  The Parties shall each bear their own costs, attorneys’ fees, and other fees incurred in connection with the preparation of this Agreement.

17.Arbitration.  The parties agree that any and all disputes arising out of the terms of this agreement, their interpretation, and any of the matters herein released, shall be subject to arbitration in Santa Clara County, California, before Judicial Arbitration & Mediation Services (“JAMS”), pursuant to its employment arbitration rules & procedures (“JAMS Rules”), on an individual basis.  The arbitrator may grant injunctions and other relief in such disputes.  The arbitrator shall administer and conduct any arbitration in accordance with the Federal Arbitration Act and California law, including the California Code of Civil Procedure, and the arbitrator shall apply substantive and procedural California law to any dispute or claim, without reference to any conflict-of-law provisions of any jurisdiction.  To the extent that the JAMS rules conflict with California law, California law shall take precedence.  The decision of the arbitrator shall be final, conclusive, and binding on the parties to the arbitration.  The parties agree that the prevailing party in any arbitration shall be entitled to injunctive relief in any court of competent jurisdiction to enforce the arbitration award.  Each party shall separately pay for its respective counsel fees and expenses; provided, however, that the arbitrator shall award attorneys’ fees and costs to the prevailing party, except as prohibited by law.  The parties hereby agree to waive their right to have any dispute between them resolved in a court of law by a judge or jury.  Notwithstanding the foregoing, this section will not prevent either party from seeking injunctive relief (or any other provisional remedy) from any court having jurisdiction over the parties and the subject matter of their dispute relating to this agreement and the agreements incorporated herein by reference.  Should any part of the arbitration agreement contained in this paragraph conflict with any other arbitration agreement between the parties, the parties agree that this arbitration agreement shall govern.

18.Tax Consequences.  The Company makes no representations or warranties with respect to the tax consequences of the payments and any other consideration provided to Employee or made on Employee’s behalf under the terms of this Agreement. Employee agrees and understands that Employee is responsible for payment, if any, of local, state, and/or federal taxes on the payments and any other consideration provided hereunder by the Company and any penalties or assessments thereon. Employee further agrees to indemnify and hold the Releasees harmless from any claims, demands, deficiencies, penalties, interest, assessments, executions, judgments, or recoveries by any government agency against the Company for any amounts claimed due on account of (a) Employee’s failure to pay or delayed payment of federal or state taxes, or (b) damages sustained by the Company by reason of any such claims, including attorneys’ fees and costs. The Parties agree and acknowledge that the payments made pursuant to Section 1 of this Agreement are not related to sexual harassment or sexual abuse and not intended to fall within the scope of 26 U.S.C. Section 162(q). 
19.Authority.

22.Attorneys’ Fees.  Except with regard to a legal action challenging or seeking a determination in good faith of the validity of the waiver herein under the ADEA, in the event that either Party brings an action to enforce or effect its rights under this Agreement, the prevailing Party shall be entitled to recover its costs and expenses, including the costs of mediation, arbitration, litigation, court fees, and reasonable attorneys’ fees incurred in connection with such an action.
23.Entire Agreement.  This Agreement represents the entire agreement and understanding between the Company and Employee (and constitutes an absolute integration of such agreement and understanding) concerning the

subject matter of this Agreement and Employee’s employment with and separation from the Company and the events leading thereto and associated therewith, and supersedes and replaces any and all prior agreements and understandings concerning the subject matter of this Agreement and Employee’s relationship with the Company, with the exception of the Confidentiality Agreement and any Equity Agreements, except as otherwise modified or superseded herein.  
24.No Oral Modification.  This Agreement may only be amended in a writing signed by Employee and the Company’s Chief Executive Officer.

2. Number of Shares; Exercise Price. This certifies that, for value received, the Investor, its Affiliates or its registered assigns
(individually and collectively, the “Warrantholder”) is entitled, upon the terms and subject to the conditions hereinafter set forth, to acquire from the Company, in whole or in part [________] fully paid and nonassessable shares of
Common Stock, as the same may be adjusted from time to time pursuant to the terms of this Warrant (the “Shares”), at a purchase price per share equal to the Exercise Price. Notwithstanding any other provision of this Warrant, if the
Warrantholder proposes to exercise this Warrant such that the Warrantholder, together with any other Person whose Company securities would be aggregated with such Warrantholder’s Company securities for purposes of any bank regulation or law,
would collectively be deemed to own, control or have the power to vote more than 9.9% of a class of the Company’s outstanding voting securities immediately following such exercise, then the Warrantholder shall instead acquire shares of Common
Stock such that the Warrantholder, together with any other Person whose Company securities would be aggregated with such Warrantholder’s Company securities for purposes of any bank regulation or law, would collectively be deemed to own, control
or have the power to vote 9.9% or less of any class of the Company’s outstanding voting securities immediately following such exercise; provided, that some or all of any shares in excess of such amount, at the election of the
Warrantholder, shall be (a) issued as either Series B Preferred Stock or Non-Voting Common Stock, or (b) provided for future issuance under the terms of this Warrant, as amended, with the exercise of
the Warrant remaining subject to the limitation prohibiting the acquisition of more than 9.9% of any class of the Company’s outstanding voting securities set forth in the preceding clause; provided, further, that the Company shall
cooperate with the Warrantholder to effectuate the issuance of such Series B Preferred Stock or Non-Voting Common Stock, or the amendment of this Warrant; and, provided, further, that all of the
representations, warranties, covenants, agreements and other provisions in this Warrant shall apply, mutatis mutandis, to any such Series B Preferred Stock, Non-Voting Common Stock, or under this
Warrant following amendment hereunder. The Exercise Price is subject to adjustment as provided herein, and all references to “Exercise Price” herein shall be deemed to include any such adjustment or series of adjustments. 

3. Exercise of Warrant; Term. (a) To the extent permitted by applicable laws and regulations, the right to purchase the Shares
pursuant to this Warrant is exercisable, in whole or in part by the Warrantholder, at any time or from time to time after the execution and delivery of this Warrant by the Company, on the date hereof, but in no event later than 11:59 p.m., New York
City time, on the seventh (7th) anniversary of the date of issuance of the Warrant, by: (i) delivery to the Company (or such other office or agency of the Company as it may designate by
notice in writing to the registered Warrantholder at the last address of the Warrantholder as it shall appear upon the warrant register of the Company) of a duly executed Notice of Exercise, the form of which is annexed hereto, in accordance with
Section 20; and (ii) within three (3) trading days after the date said Notice of Exercise is delivered to the Company, payment to the Company of the aggregate Exercise Price in respect of the Shares thereby purchased by cash,
certified or cashier’s check or wire transfer in immediately available funds to an account designated by the Company, unless the Warrantholder elects to exercise the cashless exercise procedure described in Section 3(b) below.
Notwithstanding anything herein to the contrary, the Warrantholder shall not be required to physically surrender this Warrant to the Company until the Warrantholder has purchased all of the Shares available hereunder and the Warrant has been
exercised in full in which case, the Warrantholder shall surrender this Warrant to the Company for cancellation within three (3) trading days after the date the final Notice of Exercise is delivered to the Company. Partial exercises of this
Warrant resulting in purchases of a portion 

 
of the total number of Shares available hereunder shall have the effect of lowering the outstanding number of Shares purchasable hereunder in an amount equal to the applicable number of Shares
purchased. If the Warrantholder does not exercise this Warrant in its entirety, the Warrantholder will be entitled to receive from the Company within a reasonable time, and in any event not exceeding three (3) Business Days after the date of
delivery of the applicable aggregate Exercise Price to the Company, a new warrant in substantially identical form and of the same tenor for the purchase of Shares equal to the difference between the number of Shares subject to this Warrant and the
number of Shares as to which this Warrant is so exercised. The Warrantholder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the
Shares hereunder, the number of Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof. 

(b) This Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the
Warrantholder shall be entitled to receive a certificate for the number of Shares equal to the quotient obtained by dividing [(A-B)*(X)] by (A), where: 

(A) = the Market Price on the trading day immediately preceding the date on which the Warrantholder elects to exercise this Warrant by means of
a “cashless exercise,” as set forth in the applicable Notice of Exercise; 
 (B) = the Exercise Price; and 

(X) = the number of Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise
were by means of a cash exercise rather than a cashless exercise. 
 (c) Notwithstanding anything to the contrary, the Company shall not
issue any shares of Common Stock upon the exercise of this Warrant if the issuance of such shares of Common Stock (taken together with each issuance of such shares of Common Stock (1) upon the conversion of the Series A Preferred Stock in
accordance with the Certificate of Designation, Preferences and Rights of Series A Preferred Stock or otherwise, (2) upon the conversion of the Series B Preferred Stock in accordance with the Certificate of Designation, Preferences and
Rights of Series B Preferred Stock or otherwise, (3) upon the conversion of the Non-Voting Common Stock in accordance with the Certificate of Formation as amended by the Non-Voting Common Stock Certificate of Amendment or otherwise or (4) upon the exercise of the other Warrants pursuant to the Warrant Agreements) would exceed 19.9% of the total outstanding shares of Common
Stock of the Company, or more than 19.9% of the total voting power of the Company’s securities, in each case immediately preceding the issuance of the Series A Preferred Stock and the Warrants pursuant to the Investment Agreement and the
Warrant Agreements (the number of shares which may be issued without violating such limitation, the “Exchange Cap”), except that such limitation shall not apply in the event that the Company obtains the approval of its shareholders
as required by the applicable rules of the Principal Trading Market for issuances of shares of Common Stock in excess of such amount. Until such approval is obtained, the holders of the Series A Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock and Warrants (collectively, the “Existing Buyers” and each, individually, an “Existing Buyer”) shall not be permitted to convert Series A Preferred Stock,
Series B Preferred Stock or Non-Voting Common Stock or exercise Warrants with respect to more than such Existing Buyer’s pro rata amount of such Exchange Cap (such amount, with respect to each Existing
Buyer, its “Exchange Cap Allocation Amount”) determined based upon such Existing Buyer’s percentage ownership of the sum of (1) the aggregate number of shares of Common Stock issuable upon the conversion of all shares of
Series A Preferred Stock, Series B Preferred Stock and/or Non-Voting Common Stock, plus (2) the aggregate number of shares of Common Stock issuable upon exercise of the Warrants. In the event
that such Existing Buyer shall sell or otherwise transfer any of such Existing Buyer’s shares of Series A 

 
Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock or Warrants, the transferee shall be allocated a pro rata portion of such Existing
Buyer’s Exchange Cap Allocation Amount with respect to such portion of such Series A Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock and Warrants so transferred, and the
restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation Amount so allocated to such transferee. Upon conversion and exercise in full of such Existing Buyer’s Series A
Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock and Warrants, the difference (if any) between such Existing Buyer’s Exchange Cap Allocation Amount and the number of shares of
Common Stock actually issued to such Existing Buyer upon such Existing Buyer’s conversion in full of such Series A Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock and Warrants
shall be allocated to the respective Exchange Cap Allocation Amounts of the remaining Existing Buyers of Series A Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock and Warrants on a pro
rata basis in proportion to the relative Exchange Cap Allocation Amounts of such Existing Buyers. 
 4. Issuance of Shares;
Authorization. Certificates for Shares issued upon exercise of this Warrant will be issued in such name or names as the Warrantholder may designate and will be delivered to such named Person or Persons within a reasonable time, not to exceed
three (3) Business Days after the date of delivery of the applicable aggregate Exercise Price to the Company. In lieu of delivering certificates, the Company may issue Shares issued upon exercise of this Warrant electronically in book-entry
form, in which case a statement of book-entry interests will be delivered to the Warrantholder within the aforementioned period. The Company hereby represents and warrants that any Shares issued upon the exercise of this Warrant in accordance with
the provisions of Section 3 and all other provisions of this Warrant will be duly and validly authorized and issued, fully paid and nonassessable and free from all taxes, liens and charges (other than liens or charges created by the
Warrantholder or taxes in respect of any transfer occurring contemporaneously therewith). The Company agrees that the Shares so issued will be deemed to have been issued to the Warrantholder as of the close of business on the date on which payment
of the aggregate Exercise Price is delivered to the Company in accordance with the terms of this Warrant, notwithstanding that the stock transfer books of the Company may then be closed or certificates representing such Shares may not be actually
delivered on such date. The Company will at all times hereafter reserve and keep available, out of its authorized but unissued Common Stock, solely for the purpose of providing for the exercise of this Warrant, the aggregate number of shares of
Common Stock then issuable upon exercise of this Warrant. The Company will use commercially reasonable efforts to ensure that the Shares may be issued without violation of any applicable law or regulation. 

5. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon any exercise of
this Warrant. In lieu of any fractional share to which the Warrantholder would otherwise be entitled, the Warrantholder shall be entitled to receive a cash payment in an amount equal to such fraction multiplied by the Market Price of the Common
Stock on the date of exercise. 
 6. No Rights as Shareholders; Transfer Books. This Warrant does not entitle the Warrantholder to
any voting rights or other rights as a shareholder of the Company prior to the date of exercise hereof. The Company will at no time close its transfer books against transfer of this Warrant in any manner which interferes with the timely exercise of
this Warrant. 
 7. Charges, Taxes and Expenses. Issuance of certificates for Shares to the Warrantholder upon the exercise of this
Warrant shall be made without charge to the Warrantholder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company. 

 8. Transfer/Assignment. Subject to compliance with applicable securities laws,
without obtaining the consent of the Company to assign or transfer this Warrant, this Warrant and all rights hereunder are not transferable or assignable, in whole or in part, by the Warrantholder, except for a Permitted Transfer. Upon a Permitted
Transfer, a new warrant shall be made and delivered by the Company, as promptly as reasonably practicable, of the same tenor and date as this Warrant but registered in the name of the transferee or assignee and if the Warrantholder’s entire
interest is not being transferred or assigned, in the name of the Warrantholder, upon surrender of this Warrant, duly endorsed, to the office or agency of the Company described in Section 20. All expenses (other than stock transfer taxes) and
other charges payable in connection with the preparation, execution and delivery of the new warrants pursuant to this Section 8 shall be paid by the Company. The Company may not assign any of its rights, or delegate any of its obligations,
under this Warrant without the prior written consent of the Warrantholder (which consent may be withheld for any reason or no reason at all). This Warrant shall be binding upon and inure to the benefit of the Company, the Warrantholder and their
respective successors and permitted assigns, and shall include, with respect to the Company, any Person succeeding the Company in a Business Combination or acquisition of all or substantially all of the Company’s assets, and in such case, all
of the obligations of the Company hereunder shall survive such Business Combination or acquisition. 
 9. Exchange and Registry of
Warrant. This Warrant is exchangeable, upon the surrender hereof by the Warrantholder to the Company, for a new warrant or warrants of like tenor and representing the right to purchase the same aggregate number of Shares. The Company shall
maintain a registry showing the name and address of the Warrantholder (and any transferee or assignee that becomes a Warrantholder) as the registered holder of this Warrant. This Warrant may be surrendered for exchange or exercise, in accordance
with its terms, at the office of the Company, and the Company shall be entitled to rely in all respects, prior to written notice to the contrary, upon such registry. 

10. Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the Company of evidence reasonably satisfactory to it of the
loss, theft, destruction or mutilation of this Warrant, and in the case of any such loss, theft or destruction, upon receipt of a bond, indemnity or security reasonably satisfactory to the Company, or, in the case of any such mutilation, upon
surrender and cancellation of this Warrant, the Company shall make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant, a new Warrant, in identical form, of like tenor and representing the right to purchase the same aggregate
number of Shares as provided for in such lost, stolen, destroyed or mutilated Warrant. 
 11. Saturdays, Sundays, Holidays, etc. If
the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding day that is a Business
Day. 
 12. Rule 144 Information. For so long as the Company is subject to the reporting obligations of the Securities Act and the
Exchange Act, the Company covenants that it will use its reasonable best efforts to timely file all reports and other documents required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations promulgated by the
U.S. Securities and Exchange Commission (the “SEC”) thereunder, and it will use reasonable best efforts to take such further action as the Warrantholder may reasonably request, all to the extent required from time to time to enable
the Warrantholder to sell this Warrant without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 or Regulation S under the Securities Act, as such rules may be amended from time to time, or
(ii) any successor rule or regulation hereafter adopted by the SEC. Upon the written request of the Warrantholder, the Company will deliver to the Warrantholder a written statement that it has complied with such requirements. 

 13. Adjustments and Other Rights. The Exercise Price and the number of Shares
issuable upon exercise of this Warrant pursuant to Section 3 shall be subject to adjustment from time to time as follows; provided, that no single event shall be subject to adjustment under more than one subsection of this
Section 13 so as to result in duplication and the adjustment that has the highest value relative to the rights and interests of the Warrantholder shall be made; provided, further, that, notwithstanding any provision of this
Warrant to the contrary, any adjustment shall be made to the extent (and only to the extent) that such adjustment would not cause or result in any Warrantholder and its Affiliates, collectively, being in violation of any applicable law, regulation
or rule of any governmental authority or self-regulatory organization. Any adjustment (or portion thereof) prohibited pursuant to the foregoing proviso shall be postponed and implemented on the first date on which such implementation would not
result in the condition described in such proviso. 
 (A) Common Stock Issued at Less Than the Applicable Price. 

(i) If the Company issues or sells, or agrees to issue or sell, any Common Stock, Series A Preferred Stock, Series B Preferred Stock, Non-Voting Common Stock or other securities that are convertible into or exchangeable or exercisable for Common Stock, Series A Preferred Stock, Series B Preferred Stock, or
Non-Voting Common Stock, other than Excluded Stock, for consideration per share less than the Applicable Price, then the Exercise Price in effect immediately prior to each such issuance or sale will
immediately (except as provided below) be reduced to the price determined by multiplying the Exercise Price in effect immediately prior to such issuance or sale by a fraction, (x) the numerator of which shall be the sum of (1) the number
of shares of Common Stock outstanding on a fully-diluted basis immediately prior to such issuance or sale, plus (2) the total number of shares of Common Stock which the aggregate consideration received by the Company for the total number of
such additional shares of Common Stock (or other securities that are convertible into or exchangeable or exercisable for Common Stock) so issued or sold would purchase at the Applicable Price, and (y) the denominator of which shall be the
number of shares of Common Stock outstanding on a fully-diluted basis immediately after such issuance or sale (including the number of shares of Common Stock into which such other securities are convertible or for which such other securities are
exchangeable or exercisable). In such event, the number of Shares issuable upon the exercise of this Warrant shall be increased to the number obtained by dividing (x) the product of (1) the number of Shares issuable upon the exercise of
this Warrant before such adjustment and (2) the Exercise Price in effect immediately prior to the issuance or sale giving rise to this adjustment, by (y) the new Exercise Price determined in accordance with the immediately preceding
sentence. For the avoidance of doubt, no increase in the Exercise Price or reduction in the number of Shares issuable upon exercise of this Warrant shall be made pursuant to this sub-clause (i) of this
Section 13(A). 
 (ii) For the purposes of any adjustment of the Exercise Price and the number of Shares issuable upon exercise of this
Warrant pursuant to this Section 13(A), the following provisions shall be applicable: 
 (1) In the case of the issuance
or sale of equity or equity-linked securities for cash, the amount of the consideration received by the Company shall be deemed to be the amount of the gross cash proceeds received by the Company for such securities before deducting therefrom any
discounts or commissions allowed, paid or incurred by the Company for any underwriting or otherwise in connection with the issuance and sale thereof. 

(2) In the case of the issuance or sale of equity or equity-linked securities (otherwise than upon the conversion of shares of
Capital Stock or other securities of the Company) for a consideration in whole or in part other than cash, including securities acquired in exchange therefor (other than securities by their terms so exchangeable), the consideration other than cash
shall be deemed to be the Fair Market Value, before deducting therefrom any discounts or commissions allowed, paid or incurred by the Company for any underwriting or otherwise in connection with the issuance and sale thereof. 

 (3) In the case of the issuance of (i) options, warrants or other
rights to purchase or acquire equity or equity-linked securities (whether or not at the time exercisable) or (ii) securities by their terms convertible into or exchangeable for equity or equity-linked securities (whether or not at the time so
convertible or exchangeable) or options, warrants or rights to purchase such convertible or exchangeable securities (whether or not at the time exercisable): 

(a) The aggregate maximum number of securities deliverable upon exercise of such options, warrants or other rights to purchase
or acquire equity or equity-linked securities shall be deemed to have been issued at the time such options, warrants or rights are issued and for a consideration equal to the consideration (determined in the manner provided in Section 13(A)(i)
and (ii)), if any, received by the Company upon the issuance or sale of such options, warrants or rights plus the minimum purchase price provided in such options, warrants or rights for the equity or equity-linked securities covered thereby. 

(b) The aggregate maximum number of shares of equity or equity-linked securities deliverable upon conversion of or in exchange
for any such convertible or exchangeable securities, or upon the exercise of options, warrants or other rights to purchase or acquire such convertible or exchangeable securities and the subsequent conversion or exchange thereof, shall be deemed to
have been issued at the time such securities were issued or such options, warrants or rights were issued and for a consideration equal to the consideration, if any, received by the Company for any such securities and related options, warrants or
rights (excluding any cash received on account of accrued interest or accrued dividends), plus the additional consideration (in each case, determined in the manner provided in Section 13(A)(i) and (ii)), if any, to be received by the Company
upon the conversion or exchange of such securities, or upon the exercise of any related options, warrants or rights to purchase or acquire such convertible or exchangeable securities and the subsequent conversion or exchange thereof. 

(c) On any change in the number of shares of equity or equity-linked securities deliverable upon exercise of any such options,
warrants or rights or conversion or exchange of such convertible or exchangeable securities or any change in the consideration to be received by the Company upon such exercise, conversion or exchange, but excluding changes resulting from the
anti-dilution provisions thereof (to the extent comparable to the anti-dilution provisions contained herein), the Exercise Price and the number of Shares issuable upon exercise of this Warrant shall forthwith be readjusted to such Exercise Price and
number of Shares as would have been obtained had an adjustment been made upon the issuance or sale of such options, warrants or rights not exercised prior to such change, or of such convertible or exchangeable securities not converted or exchanged
prior to such change, upon the basis of such change. 
 (d) If the Exercise Price and the number of Shares issuable upon
exercise of this Warrant shall have been adjusted upon the issuance or sale of any such options, warrants, rights or convertible or exchangeable securities, no further adjustment of the Exercise Price and the number of Shares issuable upon exercise
of this Warrant shall be made for the actual issuance of Common Stock upon the exercise, conversion or exchange thereof. 
 (iii) The
Exercise Price and the number of Shares issuable upon exercise of this Warrant pursuant to Section 3 shall not be adjusted: 

(A) for any Excluded Stock; or 

(B) for a change in the par value of Common Stock. 

 (B) Dividends, Distributions, Stock Splits, Subdivisions, Reclassifications or
Combinations. If the Company shall (i) declare a dividend or make a distribution on its Common Stock in shares of Common Stock, (ii) split, subdivide or reclassify the outstanding shares of Common Stock into a greater number of shares,
or (iii) combine or reclassify the outstanding Common Stock into a smaller number of shares, the number of Shares issuable upon exercise of this Warrant at the time of the record date for such dividend or distribution or the effective date of
such split, subdivision, combination or reclassification shall be proportionately adjusted so that the Warrantholder after such date shall be entitled to purchase the number of shares of Common Stock which such Warrantholder would have owned or been
entitled to receive on such date had this Warrant been exercised immediately prior to such date. In such event, the Exercise Price in effect at the time of the record date for such dividend or distribution or the effective date of such split,
subdivision, combination or reclassification shall be adjusted to the number obtained by dividing (x) the product of (1) the number of Shares issuable upon the exercise of this Warrant before such adjustment and (2) the Exercise Price
in effect immediately prior to the record or effective date, as the case may be, for such dividend, distribution, split, subdivision, combination or reclassification giving rise to this adjustment by (y) the new number of Shares issuable upon
exercise of this Warrant determined pursuant to the immediately preceding sentence. Notwithstanding anything to the contrary herein, if the Company declares a dividend or makes a distribution on its Common Stock in shares of Common Stock, the
Warrantholder may elect, in its sole and absolute discretion, to participate in such dividend or distribution in lieu of receiving the adjustment to the Exercise Price as described in this Section 13(B). In the event of such an election, the
dividend or distribution that the Warrantholder is entitled to receive shall be based on the amount of the dividend or distribution that the Warrantholder would have received if it had exercised this Warrant in its entirety immediately prior to the
record date of such dividend or distribution, as applicable. For the avoidance of doubt, the election under this Section 13(B) shall have no effect on any provisions of this Warrant other than as expressly set forth in this Section 13(B).

 (C) Other Distributions. In case the Company shall fix a record date for the making of a distribution to all holders of shares of
its Common Stock (i) of shares of any class other than its Common Stock other than shares referred to in Section 13(A)(i), (ii) of evidence of indebtedness of the Company or any Subsidiary of the Company, (iii) of other
securities, assets or cash (excluding dividends or distributions referred to in Section 13(B)), or (iv) of rights or warrants (other than in connection with the adoption of a shareholder rights plan), in each such case, the Exercise Price
in effect prior thereto shall be reduced immediately thereafter to the price determined by dividing (x) an amount equal to the difference resulting from (1) the number of shares of Common Stock outstanding on such record date multiplied by
the Exercise Price per Share on such record date, less (2) the amount of cash and/or the Fair Market Value of said shares or evidences of indebtedness or securities or assets or rights or warrants to be so distributed, by (y) the number of
shares of Common Stock outstanding on such record date; such adjustment shall be made successively whenever such a record date is fixed. In such event, the number of Shares issuable upon the exercise of this Warrant shall be increased to the number
obtained by dividing (x) the product of (1) the number of Shares issuable upon the exercise of this Warrant before such adjustment, and (2) the Exercise Price in effect immediately prior to the issuance giving rise to this adjustment
by (y) the new Exercise Price determined in accordance with the immediately preceding sentence. In the event that such distribution is not so made, the Exercise Price and the number of Shares issuable upon exercise of this Warrant then in
effect shall be readjusted, effective as of the date when the Board determines not to distribute such shares, evidences of indebtedness, securities, assets, cash, rights or warrants, as the case may be, to the Exercise Price that would then be in
effect and the number of Shares that would then be issuable upon exercise of this Warrant if such record date had not been fixed. 

 (D) Certain Repurchases of Common Stock. In case the Company effects a Pro Rata
Repurchase of Common Stock, then the Exercise Price shall be reduced to the price determined by multiplying the Exercise Price in effect immediately prior to the Effective Date of such Pro Rata Repurchase by a fraction of which the numerator shall
be (i) the product of (x) the number of shares of Common Stock outstanding immediately before such Pro Rata Repurchase and (y) the Market Price of a share of Common Stock on the trading day immediately preceding the first public
announcement by the Company or any of its Affiliates of the intent to effect such Pro Rata Repurchase, minus (ii) the aggregate purchase price of the Pro Rata Repurchase, and of which the denominator shall be the product of (i) (x) the
number of shares of Common Stock outstanding immediately prior to such Pro Rata Repurchase minus (y) the number of shares of Common Stock so repurchased and (ii) the Market Price per share of Common Stock on the trading day immediately
preceding the first public announcement by the Company or any of its Affiliates of the intent to effect such Pro Rata Repurchase. In such event, the number of Shares issuable upon the exercise of this Warrant shall be increased to the number
obtained by dividing (i) the product of (x) the number of Shares issuable upon the exercise of this Warrant before such adjustment, and (y) the Exercise Price in effect immediately prior to the Pro Rata Repurchase giving rise to this
adjustment by (ii) the new Exercise Price determined in accordance with the immediately preceding sentence. 
 (E) Business
Combinations. In case of any Business Combination, reorganization or reclassification of Common Stock (other than a reclassification of Common Stock referred to in Section 13(B)), or the sale, transfer or other disposal of all or
substantially all of the Company’s property, assets or business to another Person, in each case which entitles the holders of Common Stock to receive (either directly or upon subsequent liquidation) stock, securities or property (including
cash) with respect to or in exchange for Common Stock, any Shares issued or issuable upon exercise of this Warrant after the date of such Business Combination or other event shall be exchangeable for the number of shares of stock or other securities
or property (including cash) to which the Shares issuable (at the time of such Business Combination or other event) upon exercise of this Warrant immediately prior to the consummation of such Business Combination or other event would have been
entitled to receive upon consummation of such Business Combination or other event; and in any such case, if necessary, the provisions set forth herein with respect to the rights and interests thereafter of the Warrantholder shall be appropriately
adjusted so as to be applicable, as nearly as may reasonably be, to any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant. In determining the kind and amount of stock, securities or the property
receivable upon consummation of such Business Combination or other event, if the holders of Common Stock have the right to elect the kind or amount of consideration receivable upon consummation of such Business Combination or other event, then the
Warrantholder shall have the right to make a similar election upon exercise of this Warrant with respect to the number of shares of stock or other securities or property which the Warrantholder will receive upon exercise of this Warrant. In case of
any such Business Combination or other event, the successor or acquiring Person (if other than the Company) shall expressly assume the due and punctual observance and performance of each and every covenant and condition of this Warrant to be
performed and observed by the Company and all the obligations and liabilities hereunder. 
 (F) Dissolution, Total Liquidation or Winding
Up. If at any time there is a voluntary or involuntary dissolution, total liquidation or winding-up of the Company, then the Company shall provide the Warrantholder with written notice of the date on which
such dissolution, liquidation or winding-up shall take place (and, in any event, not less than thirty (30) days before any date set for definitive action). Such notice shall also specify the date as of
which the record holders of shares of Common Stock shall be entitled to exchange their shares for securities, money or other property deliverable upon such dissolution, liquidation or winding-up, as the case
may be. On such date, the Warrantholder shall be entitled to receive upon surrender of this Warrant the cash, securities or other property, less the aggregate Exercise Price for this Warrant then in effect, that the Warrantholder would have been
entitled to receive had this Warrant been exercised immediately prior to such dissolution, liquidation or winding-up. Upon receipt of the cash, securities or other property, any and all rights of the
Warrantholder to exercise this Warrant shall terminate in their entirety. If the cash, securities or other property distributable in the dissolution, liquidation or winding-up has a Fair Market Value which is
less than the aggregate Exercise Price for this Warrant then in effect, this Warrant shall terminate and be of no further force or effect upon the dissolution, liquidation or winding-up. 

 (G) Rounding of Calculations; Minimum Adjustments. All calculations under this
Section 13 shall be made to the nearest one-tenth (1/10th) of a cent or to the nearest one-hundredth (1/100th) of a share, as the case may be. Any
provision of this Section 13 to the contrary notwithstanding, no adjustment in the Exercise Price or the number of Shares issuable upon the exercise of this Warrant shall be made if the amount of such adjustment would be less than $0.01 or one-tenth (1/10th) of a share of Common Stock, respectively, but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent
adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate $0.01 or one-tenth (1/10th) of a share of Common Stock, respectively, or more. 

(H) Timing of Issuance of Additional Common Stock Upon Certain Adjustments. In any case in which the provisions of this Section 13
shall require that an adjustment shall become effective immediately after a record date for an event, the Company may defer until the occurrence of such event (i) issuing to the Warrantholder of this Warrant exercised after such record date and
before the occurrence of such event the additional Shares issuable upon such exercise by reason of the adjustment required by such event over and above the Shares issuable upon such exercise before giving effect to such adjustment and
(ii) paying to such Warrantholder any amount of cash in lieu of a fractional Share; provided, however, that the Company upon request shall deliver to such Warrantholder a due bill or other appropriate instrument evidencing such
Warrantholder’s right to receive such additional Shares, and such cash, upon the occurrence of the event requiring such adjustment. 

(I) Statement Regarding Adjustments. Whenever the Exercise Price or the number of Shares issuable upon exercise of this Warrant shall
be adjusted as provided in this Section 13, the Company shall forthwith file at the principal office of the Company a statement showing in reasonable detail the facts requiring such adjustment and the Exercise Price that shall be in effect and
the number of Shares issuable upon exercise of this Warrant after such adjustment, and the Company shall also cause a copy of such statement to be sent by mail, first class postage prepaid, to the Warrantholder at the address appearing in the
Company’s records. 
 (J) Notice of Adjustment Event. In the event that the Company shall propose to take any action of the type
described in this Section 13 (but only if the action of the type described in this Section 13 would result in an adjustment in the Exercise Price or the number of Shares issuable upon exercise of this Warrant or a change in the type of
securities or property to be delivered upon exercise of this Warrant), the Company shall give notice to the Warrantholder, in the manner set forth in Section 13(I), which notice shall specify the record date, if any, with respect to any such
action and the approximate date on which such action is to take place. Such notice shall also set forth the facts with respect thereto as shall be reasonably necessary to indicate the effect on the Exercise Price and the number, kind or class of
shares or other securities or property which shall be deliverable upon exercise of this Warrant. In the case of any action which would require the fixing of a record date, such notice shall be given at least five (5) days prior to the date so
fixed, and in case of all other action, such notice shall be given at least ten (10) days prior to the taking of such proposed action. Failure to give such notice, or any defect therein, shall not affect the legality or validity of any such
action. 
 (K) No Impairment. The Company will not, by amendment of its certificate of formation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company. 

 (L) Proceedings Prior to Any Action Requiring Adjustment. As a condition precedent to
the taking of any action which would require an adjustment pursuant to this Section 13, the Company shall take any action which may be necessary, including obtaining regulatory, stock exchange (if applicable) or shareholder approvals or
exemptions, in order that the Company may thereafter validly and legally issue as fully paid and nonassessable all shares of Common Stock that the Warrantholder is entitled to receive upon exercise of this Warrant pursuant to this Section 13.

 (M) Adjustment Rules. Any adjustments pursuant to this Section 13 shall be made successively whenever an event referred to
herein shall occur. If an adjustment in the Exercise Price made hereunder would reduce the Exercise Price to an amount below zero, then such adjustment in Exercise Price made hereunder shall reduce the Exercise Price to zero. 

14. Reserved. 
 15.
Contest and Appraisal Rights. Upon each determination of Market Price or Fair Market Value, as the case may be, hereunder, the Company shall promptly give notice thereof to the Warrantholder, setting forth in reasonable detail the calculation
of such Market Price or Fair Market Value, and the method and basis of determination thereof, as the case may be. If the Warrantholder shall disagree with such determination and shall, by notice to the Company given within fifteen (15) days
after the Warrantholder’s receipt of the Company’s notice of such determination, elect to dispute such determination, such dispute shall be resolved through the Appraisal Procedure. 

16. Representations and Warranties of the Company. The Company hereby represents and warrants to the Warrantholder that (A) it has
the corporate power and authority to execute this Warrant and consummate the transactions contemplated by this Warrant, (B) there are no statutory or contractual stockholders preemptive rights or rights of refusal with respect to the issuance
