	3.	ADMINISTRATION. 

 (a) Administration by Board. The Plan shall be
administered by the Board unless and until the Board delegates administration to a Committee or an Officer, as provided in Section 3(c) and/or Section 3(d), respectively, below. 

(b) Powers of the Board. The Board shall have the power, except as otherwise provided in the Plan: 

(i) To determine from time to time (A) which of the persons eligible under the Plan shall be granted Stock Awards; (B) when and how
the Stock Awards shall be granted; (C) what type or combination of types of Stock Awards will be granted; (D) the terms and conditions of each Stock Award granted (which need not be identical), including, without limitation, the
transferability or repurchase of such Stock Awards or Award Shares issuable thereunder, as applicable, and the circumstances under which Stock Awards become exercisable or vested or are forfeited or expire, which terms may but need not be
conditioned upon the passage of time, continued employment, the satisfaction of performance criteria, the occurrence of certain events, or other factors; and (E) the number of Award Shares subject to a Stock Award that shall be granted to a
Participant. 
 (ii) To construe and interpret the Plan and Stock Awards granted under it, and to make exceptions to any such provisions in
good faith and for the benefit of the Company, and to establish, amend and revoke rules and regulations for the Plan’s administration. The Board, in the exercise of its power, may correct any defect, omission or inconsistency in the Plan or in
any Stock Award Agreement in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effective. 
 (iii) To
settle all controversies regarding the Plan and Stock Awards granted under it. 
 (iv) To accelerate the time at which a Stock Award may
first be exercised or the time during which a Stock Award or any part thereof will vest in accordance with the Plan, notwithstanding the provisions in the Stock Award stating the time at which it may first be exercised or the time during which it
will vest. 

  
 5 

 (v) To suspend or terminate the Plan at any time. Suspension or termination of the Plan shall not
impair rights and obligations under any Stock Award granted while the Plan is in effect except with the written consent of the affected Participant. 

(vi) To submit any amendment to the Plan for stockholder approval. 

(vii) To amend the Plan in any respect the Board deems necessary or advisable to provide eligible Employees with the maximum benefits provided
or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to Incentive Stock Options or to bring the Plan or Incentive Stock Options granted under it into compliance therewith. 

(viii) To amend the terms of any one or more Stock Awards, including, but not limited to, amendments to provide terms more favorable
than previously provided in the Stock Award Agreement, subject to any specified limits in the Plan that are not subject to Board discretion; provided, however, that the rights under any Stock Award shall not be impaired by any such amendment
unless (a) the Company requests the consent of the affected Participant, and (b) such Participant consents in writing. Notwithstanding the foregoing, subject to the limitations of applicable law, if any, and without the affected
Participant’s consent, the Board may amend the terms of any one or more Stock Awards if necessary to maintain the qualified status of the Stock Award as an Incentive Stock Option or to bring the Stock Award into compliance with
Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder. 
 (ix) To
amend the Plan as provided in Section 15. 
 (x) To prescribe and amend the terms of the agreements or other documents evidencing Stock
Awards made under this Plan (which need not be identical). 
 (xi) To place such restrictions on the sale or other disposition of Award
Shares as may be deemed appropriate by the Board. 
 (xii) To determine whether, and the extent to which, adjustments are required pursuant
to Section 10. 
 (xiii) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to
promote the best interests of the Company. 
 (c) Delegation to a Committee. The Board may delegate administration of the Plan
to a committee of the Board composed of not fewer than two (2) members (the “Committee”). If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers
theretofore possessed by the Board (and references in the Plan to the Board shall thereafter be deemed to be references to the Committee), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted
from time to time by the Board. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan. 

  
 6 

 (d) Delegation to an Officer. The Board may delegate to one or more Officers of the
Company the authority to do one or both of the following (i) designate Employees who are not Officers to be recipients of Stock Awards and the terms thereof, and (ii) determine the number of shares of Common Stock to be subject to Stock
Awards granted to such Employees; provided, however, that the Board resolutions regarding such delegation shall specify the total number of shares of Common Stock that may be subject to the Stock Awards granted by such Officer
and that such Officer may not grant a Stock Award to himself or herself. Notwithstanding anything to the contrary in this Section 3(d), the Board may not delegate to an Officer authority to determine the Fair Market Value of the Common Stock as
herein contemplated. 
 (e) Effect of Change in Status. The Board shall have the absolute discretion to determine the
effect upon a Stock Award, and upon an individual’s status as an Employee, Consultant or Director under the Plan, including whether a Participant shall be deemed to have experienced a Termination of Service or other change in status, and upon
the vesting, expiration or forfeiture of a Stock Award or Award Shares issuable in respect thereof, in the case of (i) a Termination of Service for Cause, (ii) any leave of absence approved by the Company or an Affiliate, (iii) any
transfer between the Company and any Affiliate or between any Affiliates, (iii) any change in the Participant’s status from an Employee to a Consultant or member of the Board of Directors, or vice versa, and (v) any Employee who
becomes employed by any partnership, joint venture, corporation or other entity not meeting the requirements of an Affiliate. 

(f) Determinations of the Board. All decisions, determinations and interpretations by the Board regarding this Plan shall be
final and binding on all Participants or other persons claiming rights under the Plan or any Stock Award. The Board shall consider such factors as it deems relevant to making such decisions, determinations and interpretations including, without
limitation, the recommendations or advice of any Director, Officer or Employee of the Company and such attorneys, consultants and accountants as it may select. A Participant or other holder of a Stock Award may contest a decision or action by the
Board with respect to such person or Stock Award only on the grounds that such decision or action was arbitrary or capricious or was unlawful, and any review of such decision or action shall be limited to determining whether the Board’s
decision or action was arbitrary or capricious or was unlawful. 
 (g) Arbitration. Any dispute or claim concerning any
Stock Awards granted (or not granted) pursuant to the Plan or any disputes or claims relating to or arising out of the Plan shall be fully, finally and exclusively resolved by binding and confidential arbitration conducted pursuant to the rules of
Judicial Arbitration and Mediation Services, Inc. (“JAMS”) in the County of Los Angeles, California. In addition to any other relief, the arbitrator may award to the prevailing party recovery of its attorneys’ fees and costs.
By accepting a Stock Award, Participants and the Company waive their respective rights to have any such disputes or claims tried by a judge or jury. 
  

	4.	SHARES SUBJECT TO THE PLAN. 

Subject to the provisions of Section 10 relating to adjustments upon changes in stock, the Award Shares that may be issued pursuant to
Stock Awards shall not exceed in the aggregate Eighteen Million Five Hundred Fifty-One Thousand Fifty-Five (18,551,055) shares of the 

  
 7 

 
Company’s Common Stock. Of such amount, Eighteen Million Five Hundred Fifty-One Thousand Fifty-Five (18,551,055) Award Shares may be issued pursuant to Incentive Stock Options. In the
event that (a) all or any portion of any Stock Award granted or offered under the Plan can no longer under any circumstances be exercised or otherwise become vested, or (b) any Award Shares are reacquired by the Company which were
initially the subject of a Stock Award Agreement, the Award Shares allocable to the unexercised or unvested portion of such Stock Award, or the Award Shares so reacquired, shall again be available for grant or issuance under the Plan. 

 

	5.	ELIGIBILITY. 

 (a) General. Incentive
Stock Options may be granted only to Employees; all other Stock Awards may be granted only to Employees, Directors and Consultants. In the event a Participant is both an Employee and a Director, or a Participant is both a Director and a Consultant,
the Stock Award Agreement shall specify the capacity in which the Participant is granted the Stock Award; provided, however, if the Stock Award Agreement is silent as to such capacity, the Stock Award shall be deemed to be granted to the
Participant as an Employee or as a Consultant, as applicable. 
 (b) Ten Percent Stockholders. A Ten Percent
Stockholder shall not be granted an Incentive Stock Option unless the exercise price of such Option is at least one hundred ten percent (110%) of the Fair Market Value of the Common Stock at the date of grant and the Option is not exercisable
after the expiration of five (5) years from the date of grant. 
 (c) Consultants. A Consultant shall not be
eligible for the grant of a Stock Award if, at the time of grant, either the offer or the sale of the Company’s securities to such Consultant is not exempt under Rule 701 of the Securities Act (“Rule 701”) because of the nature
of the services that the Consultant is providing to the Company, because the Consultant is not a natural person, or because of any other provision of Rule 701, unless the Company determines that such grant need not comply with the requirements of
Rule 701 and will satisfy another exemption under the Securities Act as well as comply with the securities laws of all other relevant jurisdictions. 
  

	6.	OPTION AGREEMENT PROVISIONS. 

 Each
Option shall be granted pursuant to a written Option Agreement, signed by an Officer of the Company and by the Optionee, which shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The provisions of
separate Option Agreements need not be identical, but each Option Agreement shall include (through incorporation of the provisions hereof by reference in the Option Agreement or otherwise) the substance of each of the following provisions (except to
the extent that any such provision indicates it is permissible rather than mandatory): 
 (a) Term. No Incentive
Stock Option shall be exercisable after the expiration of ten (10) years from the date of its grant or such shorter period specified in the Option Agreement; provided, however, that an Incentive Stock Option granted to a Ten Percent
Stockholder shall be subject to the provisions of Section 5(b). 

  
 8 

 (b) Exercise Price of an Option. Subject to the provisions of Section 5(b)
regarding Incentive Stock Options granted to Ten Percent Stockholders, the exercise price of each Incentive Stock Option shall be not less than the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. The
Board shall determine the exercise price of each Nonstatutory Stock Option. Notwithstanding the foregoing, an Incentive Stock Option may be granted with an exercise price lower than one hundred percent (100%) of the Fair Market Value of the
Common Stock subject to the Option if such Incentive Stock Option is granted pursuant to an assumption of or substitution for another option in a manner consistent with the provisions of Section 424(a) of the Code. 

(c) Consideration. The purchase price of Common Stock acquired pursuant to the exercise of an Option shall be paid, to the
extent permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board shall have the authority to grant Options that do not permit all of the following
methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to utilize a particular method of payment. The methods of payment permitted by this Section 6(c) are:

 (i) by cash or check; 

(ii) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common
Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds; 

(iii) by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock; 

(iv) by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issued upon
exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; provided, however, that the Company shall accept a cash or other payment from the Participant to the extent of any
remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued; provided, further, however, that shares of Common Stock will no longer be outstanding under an Option and will not
be exercisable thereafter to the extent that (A) shares are used to pay the exercise price pursuant to the “net exercise,” (B) shares are delivered to the Participant as a result of such exercise, and (C) shares are withheld
to satisfy tax withholding obligations; or 
 (v) in any other form of legal consideration that may be acceptable to the Board. 

(d) Transferability. The following restrictions on the transferability of Options shall apply: 

(i) Restrictions on Transfer. An Option shall not be transferable except by will or by the laws of descent and
distribution and shall be exercisable during the lifetime of the  

  
 9 

 
Optionee only by the Optionee; provided, however, that the Board may, in its sole discretion, permit transfer of the Option to a revocable trust or as otherwise permitted by Rule 701 of the
Securities Act. Notwithstanding the foregoing, however, an Incentive Stock Option shall not be transferable other than by will or the laws of descent and distribution, and shall be exercisable only by the Optionee during the Optionee’s
lifetime, except as otherwise permitted by the Board and by Sections 421, 422 and 424 of the Code and the regulations and other guidance thereunder. 

(ii) Domestic Relations Orders. Notwithstanding the foregoing, an Option may be transferred pursuant to a domestic
relations order; provided, however, that if an Option is an Incentive Stock Option, such Option shall be deemed to be a Nonstatutory Stock Option as a result of such transfer. 

(iii) Beneficiary Designation. Notwithstanding the foregoing, the Optionee may, by delivering written notice to the
Company, in a form provided by or otherwise satisfactory to the Company, designate a third party who, in the event of the death of the Optionee, shall thereafter be the beneficiary of an Option with the right to exercise the Option and receive the
Common Stock or other consideration resulting from an Option exercise. In the absence of such a designation, the executor or administrator of the Optionee’s estate shall be entitled to exercise the Option and receive the Common Stock or other
consideration resulting from an Option exercise. 
 (e) Vesting. Each Option shall vest and become exercisable in one
or more installments, at such time or times and subject to such conditions, including without limitation the achievement of specified performance goals or objectives established with respect to one or more performance criteria, as shall be
determined by the Board. 
 (f) Termination of Service. In the event of the Termination of Service of an Optionee for
any reason (other than for “Cause,” as defined in a Stock Option Agreement, or upon the Optionee’s death or Disability), the Optionee may exercise his or her Option, but only within such period of time as is set forth in the Option
Agreement (and in no event later than the expiration of the term of such Option as set forth in the Option Agreement). In the case of an Incentive Stock Option, such exercise period provided in the Option Agreement shall not exceed three
(3) months from the date of termination. 
 (g) Disability of Optionee. In the event of a Termination of Service
of an Optionee as a result of the Optionee’s Disability, the Optionee may exercise his or her Option within the period specified in the Option Agreement (in no event to exceed twelve (12) months from the date of such termination in the
case of an Incentive Stock Option), and only to the extent that the Optionee was entitled to exercise the Option at the date of such termination (but in no event later than the expiration of the term of such Option as set forth in the Option
Agreement). 
 (h) Death of Optionee. In the event that (i) an Optionee’s Termination of Service occurs as a
result of the Optionee’s death, or (ii) an Optionee dies within the period (if any) specified in the Option Agreement after the Optionee’s Termination of Service for a reason other than death, then, notwithstanding Section 6(f)
above, the Option may be exercised (to the extent the Optionee was entitled to exercise such Option as of the date of death) by the Optionee’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by 

  
 10 

 a person designated to exercise the option upon the Optionee’s death, but only within the period ending on
the earlier of (i) the date that is twelve (12) months after the date of Termination of Service, or (ii) the expiration of the term of such Option as set forth in the Option Agreement. 

(i) Termination for Cause. In the event of the Termination of Service of an Optionee for Cause, except as otherwise determined
by the Board in the specific situation, all Options granted to such Optionee shall expire as set forth in the Stock Option Agreement. 

(j) Extension of Termination Date. An Optionee’s Option Agreement may provide that if the exercise of the Option following
an Optionee’s Termination of Service (other than for Cause or upon the Optionee’s death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would violate the registration requirements under
the Securities Act, then the Option shall terminate on the earlier of (i) the expiration of a period of three (3) months after the termination of the Optionee’s Continuous Service during which the exercise of the Option would not be
in violation of such registration requirements, or (ii) the expiration of the term of the Option as set forth in the Option Agreement. 

(k) Non-Exempt Employees. No Option granted to an Employee that is a non-exempt employee for purposes of the Fair Labor
Standards Act of 1938, as amended, shall be first exercisable for any shares of Common Stock until at least six months following the date of grant of the Option. The foregoing provision is intended to operate so that any income derived by a
non-exempt employee in connection with the exercise or vesting of an Option will be exempt from his or her regular rate of pay. 

(l) Early Exercise. The Option may, but need not, include a provision whereby the Optionee may elect at any time prior to a
Termination of Service to exercise the Option as to any part or all of the Option Shares prior to the full vesting of the Option. Any unvested Option Shares so purchased may be subject to an unvested share repurchase option in favor of the Company
or to any other restriction the Board determines to be appropriate. 
 (m) Right of Repurchase. The Option Agreement
may, but need not, include a provision whereby the Company may elect to repurchase all or any part of the vested shares of Common Stock acquired by the Optionee pursuant to the exercise of the Option. 

(n) Right of First Refusal. The Option Agreement may, but need not, include a provision whereby the Company may elect to
exercise a right of first refusal following receipt of notice from the Optionee of the intent to transfer all or any part of the shares of Common Stock received upon the exercise of the Option. 

 

	7.	PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS. 

(a) Stock Bonus Awards. Each stock bonus agreement shall be in such form and shall contain such terms and conditions as the Board
shall deem appropriate. The terms and conditions of stock bonus agreements may change from time to time, and the terms and conditions of separate stock bonus agreements need not be identical, but each stock bonus agreement shall include (through
incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions (except to the extent that any such provision indicates it is permissible rather than mandatory): 

(i) Consideration. A stock bonus may be awarded in consideration for past services actually rendered to the Company or an
Affiliate for its benefit, provided that the Participant remains eligible to receive Stock Awards hereunder at the time of the award. 

  
 11

but need not, be subject to a share repurchase option in favor of the Company in accordance with a vesting schedule to be determined by the Board. 

(iii) Termination of Service. In the event of a Termination of Service, the Company may reacquire any or all of the Award
Shares held by the Participant which have or have not vested as of the date of termination under the terms of the stock bonus agreement. 

(iv) Transferability. Unless otherwise determined by the Board, rights to acquire Award Shares under the stock bonus
agreement shall not be transferable except by will or by the laws of descent and distribution, or, to the extent permitted by the Board, to a revocable trust or as otherwise permitted by Rule 701 of the Securities Act. 

(b) Restricted Stock Purchase Awards. Each restricted stock purchase agreement shall be in such form and shall contain such
terms and conditions as the Board shall deem appropriate. The terms and conditions of the restricted stock purchase agreements may change from time to time, and the terms and conditions of separate restricted stock purchase agreements need not be
identical, but each restricted stock purchase agreement shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions (except to the extent that any such
provision indicates it is permissible rather than mandatory): 
 (i) Purchase Price. The purchase price under
each restricted stock purchase agreement shall be such amount as the Board shall determine and designate in such restricted stock purchase agreement, including no consideration or such minimum consideration as may be required by applicable law.

 (ii) Consideration. The purchase price of Common Stock acquired pursuant to the restricted stock purchase
agreement, if any, shall be paid either: (a) in cash at the time of purchase; (b) at the discretion of the Board, according to a deferred payment or other similar arrangement with the Participant; or (c) in any other form of legal
consideration that may be acceptable to the Board in its discretion.

under the restricted stock purchase agreement may, but need not, be subject to a share repurchase option in favor of the Company in accordance with a vesting schedule to be determined by the Board. 

(iv) Termination of Service. In the event of a Participant’s Termination of Service, the Company may repurchase or
otherwise reacquire any or all of the Award Shares held by the Participant which have or have not vested as of the date of termination under the terms of the restricted stock purchase agreement. 

(v) Transferability. Unless otherwise determined by the Board, rights to acquire Award Shares under the restricted stock
purchase agreement shall not be transferable except by will, by the laws of descent and distribution, or, to the extent permitted by the Board, to a revocable trust or as otherwise permitted by Rule 701 of the Securities Act.

	8.	COVENANTS OF THE COMPANY. 

(a) Availability of Shares. During the terms of the Stock Awards, the Company shall keep available at all times the number of
shares of Common Stock required to satisfy such Stock Awards. 
 (b) Compliance with Laws and Regulations. This Plan,
the grant and exercise of Stock Awards thereunder, and the obligation of the Company to sell, issue or deliver Award Shares under such Stock Awards, shall be subject to all applicable federal, state and local laws, rules and regulations and to such
approvals by any governmental or regulatory agency as may be required. The Company shall not be required to register in a Participant’s name or deliver any Award Shares prior to the completion of any registration or qualification of such Shares
under any federal, state or local law or any ruling or regulation of any government body which the Board shall determine to be necessary or advisable. To the extent the Company is unable to or the Board deems it infeasible to obtain authority from
any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary or advisable for the lawful issuance and sale of any Award Shares hereunder, the Company shall be relieved of any liability with respect
to the failure to issue or sell such Award Shares as to which such requisite authority shall not have been obtained. No Option shall be exercisable and no Award Shares shall be issued and/or transferable under any other Stock Award unless a
registration statement with respect to the Award Shares underlying such Stock Award is effective and current or the Company has determined that such registration is unnecessary. 

 

	9.	USE OF PROCEEDS. 

 Proceeds from the
sale of Award Shares shall constitute general funds of the Company and shall be used for general operating capital of the Company. 
  

	10.	ADJUSTMENTS UPON CHANGE IN COMMON STOCK. 

If any change is made in the Common Stock subject to the Plan or subject to any Stock Award without the receipt of consideration by the Company
(through merger, consolidation, reorganization, recapitalization, reclassification, stock dividend, dividend in property other than cash, stock split, reverse stock split, liquidating dividend, exchange of shares, change in corporate structure or
other distribution of the Company’s equity securities), the Plan and all outstanding Stock Awards will be appropriately adjusted in the class and maximum number of shares subject to the Plan and the class and number of shares and price per
share of Common Stock subject to outstanding Stock Awards. Such adjustment shall be made by the Board, the determination of which shall be final, binding and conclusive. 

  
 13 

	11.	ADJUSTMENTS UPON CHANGE IN CONTROL. 

(a) The Board shall have the discretion to provide in each Stock Award Agreement the terms and conditions that relate to
(i) vesting of such Stock Award in the event of a Change in Control, and (ii) assumption of such Stock Award Agreements or issuance of comparable securities under an incentive program in the event of a Change in Control. The aforementioned
terms and conditions may vary in each Stock Award Agreement. 
 (b) If the terms of an outstanding Option Agreement provide
for accelerated vesting in the event of a Change in Control, or to the extent that an Option is vested and not yet exercised, the Board in its discretion may provide, in connection with the Change in Control transaction, for the purchase or exchange
of each Option for an amount of cash or other property having a value equal to the difference (or “spread”) between: (x) the value of the cash or other property that the Optionee would have received pursuant to the Change in Control
transaction in exchange for the vested Option Shares issuable upon exercise of the Option had the Option been exercised immediately prior to the Change in Control, and (y) the aggregate exercise price of the vested Option Shares. If in such
case the aggregate exercise price of the vested Option Shares is greater than or equal to the value of the cash or other property that the Optionee would have received pursuant to the Change in Control transaction in exchange for the vested Option
Shares had the Option been exercised immediately prior to the Change in Control, then the Option shall be cancelled and Optionee shall receive no payment for such Option Shares. Upon such purchase, exchange or cancellation, the Option shall be
terminated and Optionee shall have no further rights with respect to such Option. 
 (c) Outstanding Options shall terminate
and cease to be exercisable upon consummation of a Change in Control except to the extent that the Options are assumed by the successor entity (or parent thereof) pursuant to the terms of the Change in Control transaction. 

 

	12.	ACCELERATION OF EXERCISABILITY AND VESTING. 

The Board shall have the power to accelerate the time at which any or all Stock Awards may first be exercised or the time during which any or
all Stock Awards or any part thereof will vest in accordance with the Plan, notwithstanding the provisions in any Stock Award stating the time at which it may first be exercised or the time during which it will vest. By approval of the Plan, the
Company’s stockholders consent to any such accelerations in the Board’s sole discretion. 
  

	13.	DISSOLUTION OR LIQUIDATION. 

 In the
event of a dissolution or liquidation of the Company, then all outstanding Stock Awards shall terminate immediately prior to such event. 
  

	14.	MISCELLANEOUS. 

 (a) Stockholder Rights. Neither a
Participant nor any person to whom a Stock Award is transferred shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any Award Shares unless and until such person has satisfied all requirements for
exercise of the Stock Award pursuant to its terms and the Company has duly issued a stock certificate for such Award Shares. 

  
 14 

 (b) No Employment or Other Service Rights. Nothing in the Plan or any Stock Award
Agreement shall confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Stock Award was granted or shall affect the right of the Company or an Affiliate to terminate
(i) the employment of an Employee with or without notice and with or without Cause; (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate; or (iii) the service of a
Director pursuant to the Bylaws or Certificate of Incorporation of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be. 

(c) Incentive Stock Option $100,000 Limitation. To the extent that the aggregate Fair Market Value (determined at the time of
grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionee during any calendar year (under all plans of the Company and any Affiliates) exceeds One Hundred Thousand Dollars ($100,000), the
Options or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s). 

(d) Investment Assurances. The Company may require a Participant, as a condition of exercising an Option or otherwise acquiring
Common Stock under any Stock Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably
satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Stock Award;
and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Stock Award for the Participant’s own account and not with any present intention of selling or otherwise
distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (x) the issuance of the shares upon the exercise or acquisition of Common Stock under the Stock Award has
been registered under a then currently effective registration statement under the Securities Act; or (y) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the
circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with
applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock. 
 (e)
Withholding Obligations. The Company may, in its sole discretion, satisfy any federal, state or local tax withholding obligation relating to a Stock Award by any of the following means (in addition to the Company’s right to withhold
from any compensation paid to the Participant by the Company) or by a combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of Common Stock from the shares of Common 

  
 15 

 
Stock issued or otherwise issuable to the Participant in connection with the Stock Award, provided that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax
required to be withheld by law (or such lower amount as may be necessary to avoid classification of the Stock Award as a liability); or (iii) by such other method as may be set forth in the Stock Award Agreement. 

(f) Compliance with Section 409A of the Code. To the extent applicable, the Plan and Stock Award Agreements shall be
interpreted in accordance with Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued or amended
after the Effective Date (as defined in Section 17 below). Notwithstanding any provision of the Plan or Stock Award to the contrary, in the event that following the Effective Date the Board determines that any Stock Award may be subject to
Section 409A of the Code and related Department of Treasury guidance (including such Department of Treasury guidance as may be issued after the Effective Date), the Board may adopt such amendments to the Plan and the applicable Stock Award
Agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Board determines are necessary or appropriate to (i) exempt the Stock Award from
Section 409A of the Code and/or preserve the intended tax treatment of the benefits provided with respect to the Stock Award; or (ii) comply with the requirements of Section 409A of the Code and Department of Treasury regulations and
other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued or amended after the Effective Date. 

 

	15.	AMENDMENT OF THE PLAN. 

(a) In General. The Board at any time, and from time to time, may amend the Plan. However, no amendment shall be effective unless
approved by the stockholders of the Company within twelve (12) months before or after the adoption of the amendment where the amendment will: 

(i) Increase the number of shares reserved for Stock Awards under the Plan, except as provided in Section 10 relating to adjustments upon
changes in Common Stock; 
 (ii) Modify the requirements as to eligibility for participation in the Plan (to the extent such modification
requires stockholder approval in order for the Plan to satisfy the requirements of Section 422 of the Code); or 
 (iii) Modify the
Plan in any other way if such modification requires stockholder approval in order for the Plan to satisfy the requirements of Section 422 of the Code. 

(b) Amendment to Maximize Benefits. It is expressly contemplated that the Board may amend the Plan in any respect the Board
deems necessary or advisable to provide Participants with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to Incentive Stock Options and/or to bring the Plan and/or
Incentive Stock Options granted under the Plan into compliance therewith. 
 (c) No Impairment. The
rights and obligations under any Stock Award granted before any amendment of the Plan shall not be altered or impaired by such amendment unless the Company requests the consent of the person to whom the Stock Award was granted and such person
consents in writing; provided, however, that notwithstanding anything to the contrary in this Section 15 or elsewhere in this Plan, no such consent shall be required with respect to any amendment or alteration if the Board determines in
its sole discretion that such amendment or alteration either (i) is required or advisable in order for the Company, the Plan or the Stock Award to satisfy or conform to any law or regulation or to meet the requirements of any accounting
standard, or (ii) is not reasonably likely to significantly diminish the benefits provided under such Award, or that any such diminishment has been adequately compensated. 

  
 16 

	16.	TERMINATION OR SUSPENSION OF THE PLAN. 

(a) Termination or Suspension. The Board may suspend or terminate the Plan at any time. Unless sooner terminated, the Plan shall
terminate on March 12, 2018 (which shall be within ten (10) years from the date the Plan is adopted by the Board or approved by the stockholders of the Company, whichever is earlier), and no Stock Awards may be granted under the Plan while
the Plan is suspended or after it is terminated, but Stock Awards and Stock Award Agreements then outstanding shall continue in effect in accordance with their respective terms. 

(b) No Impairment. Rights and obligations under any Stock Award granted while the Plan is in effect shall not be altered or
impaired by suspension or termination of the Plan, except as otherwise provided herein or with the consent of the person to whom the Stock Award was granted. 
  

	17.	EFFECTIVE DATE OF PLAN. 

The Plan shall become effective on March 12, 2008, which is the date that the Plan was adopted by the Board, provided that the
stockholders of the Company approve or have approved the Plan within twelve (12) months of such date (the “Effective Date”). No Options granted under the Plan shall be exercised unless and until the Plan has been approved by
the stockholders of the Company, and all Stock Awards granted under the Plan shall be rescinded if stockholder approval of the Plan is not obtained within such 12-month period. 

 

	18.	NON-EXCLUSIVITY OF THE PLAN 

Neither the adoption of this Plan by the Board nor the submission of this Plan to the stockholders of the Company for approval shall be
construed as creating any limitations on the power of the Board to adopt such other incentive arrangements as either may deem desirable, including, without limitation, the granting of stock options or restricted stock otherwise than under this Plan,
and such arrangements may be either generally applicable or applicable only in specific cases. 
  

	19.	LIABILITY OF THE COMPANY. 

The Company and the members of the Board shall not be liable to a Participant or any other persons as to: (a) the non-issuance or
non-transfer, or any delay of issuance or transfer, of 

  
 17 

 
any Award Shares which results from the inability of the Company to comply with, or to obtain, or from any delay in obtaining from any regulatory body having jurisdiction, all requisite authority
to issue or transfer Award Shares if counsel for the Company deems such authority reasonably necessary for lawful issuance or transfer of any such shares and, in furtherance thereof, appropriate legends may be placed on the stock certificates
evidencing Award Shares to reflect such transfer restrictions; and (b) any tax consequence expected, but not realized, by any Participant or other person due to the receipt, exercise or settlement of any Option or other Stock Award granted
hereunder. 
  

	20.	CHOICE OF LAW. 

 The laws of the
State of California shall govern all questions concerning the construction, validity and interpretation of this Plan, without regard to such state’s conflict of laws rules.

 OPTION AGREEMENT 

EVERBRIDGE, INC. 2008 EQUITY INCENTIVE
PLAN 
 (INCENTIVE STOCK OPTION OR
NONSTATUTORY STOCK OPTION) 
 Effective as of May 12, 2008 

Pursuant to the Stock Option Grant Notice (“Grant Notice”) and this Option Agreement (“Option Agreement”),
Everbridge Inc. (the “Company”) has granted to Optionee an option under its 2008 Equity Incentive Plan (the “Plan”), to purchase the number of shares of the Company’s Common Stock indicated in Optionee’s
Grant Notice, at the exercise price indicated in such Grant Notice. This Option Agreement is incorporated by reference into and made a part of the Grant Notice. Whenever capitalized terms are used in this Option Agreement, they shall have the
meaning specified (i) in the Plan, (ii) in the relevant Grant Notice, or (iii) below, unless the context clearly indicates to the contrary. 

The details of the Option granted to Optionee are as follows: 

1. Term of Option. Subject to the maximum time limitations in Sections 5(b) and 6(a) of the Plan, the term of the Option shall be the
period commencing on the Date of Grant and ending on the Expiration Date (as defined in the Grant Notice), unless terminated earlier as provided herein or in the Plan. 

2. Exercise Price. The Exercise Price of the Option granted hereby shall be as provided in the Grant Notice. 

3. Exercise of Option. 

(a) The Grant Notice sets forth the rate at which the Option Shares shall become subject to purchase (“vest”) by Optionee.

 (b) In the event of a Change in Control of the Company, except as otherwise may be provided in the Plan or Grant Notice, the vesting of
the Option shall not accelerate, and the Option shall terminate if not exercised (to the extent then vested and exercisable) at or prior to such Change in Control. 

(c) Optionee shall exercise the Option, to the extent exercisable, in whole or in part, by sending written notice to the Company on a Notice
of Exercise in the form attached to the Grant Notice of his or her intention to purchase Option Shares hereunder, together with a check in the amount of the full purchase price of the Option Shares to be purchased, or such other form of payment as
permitted by the Grant Notice. Except as otherwise consented to by the Company, Optionee shall not exercise the Option at any one time with respect to less than five percent (5%) of the total Option Shares set forth in the Grant Notice unless
Optionee exercises all of the Option then vested and exercisable. 

 (d) If the Option is an Incentive Stock Option, by Optionee’s exercise of the Option,
Optionee agrees that he or she will notify the Company in writing within fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of the Option that occurs within two (2) years after
the date of the Date of Grant or within one (1) year after such shares of Common Stock are transferred upon exercise of the Option. 

(e) Optionee agrees to complete and execute any additional documents which the Company reasonably requests that Optionee complete in order to
comply with applicable federal, state and local securities laws, rules and regulations. 
 (f) Subject to the Company’s compliance with
all applicable laws, rules and regulations relating to the issuance of such Option Shares and Optionee’s compliance with all the terms and conditions of the Grant Notice, this Option Agreement, and the Plan, the Company shall promptly deliver
the Option Shares to Optionee. 
 (g) Except as otherwise provided herein or in the Plan, the Option may be exercised during the lifetime of
Optionee only by Optionee. 
 (h) In the event that Optionee is an Employee eligible for overtime compensation under the Fair Labor
Standards Act of 1938, as amended (i.e., a “Non-Exempt Employee”), Optionee may not exercise his or her Option until the later date (i) that he or she shall have completed at least six (6) months of service to the Company
measured from the Date of Grant specified in Optionee’s Grant Notice, or (ii) the date set forth in the Grant Notice. 
 4.
Exercise Prior to Vesting (“Early Exercise”). If expressly permitted by the Grant Notice and subject to the provisions of this Option Agreement, Optionee may, at any time that is both (i) prior to a Termination of Service; and
(ii) prior to the Expiration Date, elect to exercise all or part of the Option, including the nonvested portion of the Option; provided, however, that: 

(a) a partial exercise of the Option shall be deemed to cover first any vested Option Shares and then the earliest vesting installment(s) of
unvested Option Shares; 
 (b) any Option Shares so purchased from installments which have not vested as of the date of exercise shall be
subject to a purchase option in favor of the Company, pursuant to an Early Exercise Stock Purchase Agreement in form satisfactory to the Company; 

(c) Optionee shall enter into the Early Exercise Stock Purchase Agreement with a vesting schedule that will result in the same vesting as if
no early exercise had occurred; and 
 (d) as provided in the Plan, if the Option is an Incentive Stock Option, to the extent that the
aggregate Fair Market Value (determined at the time of grant) of Common Stock with respect to which the Option plus all other Incentive Stock Options held by Optionee are exercisable for the first time during any calendar year (under all plans of
the Company and its Affiliates) exceeds One Hundred Thousand Dollars ($100,000), the Options or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options. 

  
 2 

 5. Option Not Transferable. The Option granted hereunder shall not be transferable in any
manner other than as provided in Section 6(d) of the Plan. More particularly (but without limiting the foregoing), the Option may not be assigned, transferred (except as expressly provided in the Plan), pledged or hypothecated in any way, shall
not be assignable by operation of law and shall not be subject to execution, attachment or similar process. Any attempted assignment, transfer, pledge, hypothecation or other disposition of the Option contrary to the provisions hereof, or the levy
of any execution, attachment or similar process upon the Option, shall be null and void and without effect. 
 6. Termination of
Option. 
 (a) To the extent not previously exercised, the Option shall terminate on the Expiration Date; provided, however, that except
as otherwise provided in this Section 6, the Option may not be exercised more than sixty (60) days after the Termination of Service of Optionee for any reason (other than for Cause, as defined in the Plan, or upon Optionee’s death
or Disability). Within such sixty (60)-day period, except as may otherwise be specifically provided in this Option Agreement or any other agreement between Optionee and the Company which has been approved by the Board, Optionee may exercise the
Option only to the extent the same was exercisable on the date of such termination and said right to exercise shall terminate at the end of such period. 

(b) In the event of the Termination of Service of Optionee as a result of Optionee’s Disability, the Option shall be exercisable for a
period of six (6) months from the date of such termination, but in no event later than the Expiration Date and only to the extent that the Option was exercisable on the date of such termination. 

(c) In the event of the Termination of Service of Optionee as a result of Optionee’s death, the Option shall be exercisable by
Optionee’s estate (or by the person who acquires the right to exercise the Option by will or by the laws of descent and distribution) for a period of twelve (12) months from the date of such termination, but in no event later than the
Expiration Date and only to the extent that Optionee was entitled to exercise the Option on the date of death. 
 (d) In the event of the
Termination of Service of Optionee for Cause (as defined below), unless otherwise determined by the Board, (A) the Option shall expire as of the date of the first occurrence giving rise to such termination or upon the Expiration Date, whichever
is earlier; (B) Optionee shall have no rights with respect to any unexercised portion of the Option; and (C) any Option Shares issued in respect of the exercise of the Option on or after the date of the first act and/or event constituting
Cause shall have occurred shall be deemed to have been issued in respect of an expired option, and shall thereupon be deemed null and void ab initio, and Optionee shall have no claims to, or rights in, any such Option Shares. “Cause” means
with respect to Optionee, the occurrence of any of the following events, as reasonably determined by the Board in each case: (i) Optionee’s commission of any felony or any crime 

  
 3 

 
involving fraud, dishonesty or moral turpitude under the laws of the United States or any state thereof; (ii) Optionee’s commission, or attempted commission, of, or participation in, a
fraud or act of dishonesty against the Company or any Affiliate, or any of their respective employees, officers or directors; (iii) Optionee’s intentional, material violation of any contract or agreement between the Optionee and the
Company or any Affiliate or of any statutory duty owed to the Company or any Affiliate; (iv) Optionee’s unauthorized use or disclosure of the Company’s or an Affiliate’s material confidential information or trade secrets;
(v) Optionee’s gross misconduct in connection with Optionee’s service to the Company or an Affiliate; or (vi) Optionee’s failure to promptly return all documents and other tangible items belonging to the Company or its
Affiliates in the Participant’s possession or control, including all complete or partial copies, recordings, abstracts, notes or reproductions of any kind made from or about such documents or information contained therein, upon a Termination of
Service for any reason. “Cause” shall not require that a civil judgment or criminal conviction have been entered against, or guilty plea shall have been made by, Optionee regarding any of the matters referred to in clauses (i) through
(vi). Accordingly, the Board shall be entitled to determine “Cause” based on the its good faith belief. If the Optionee is criminally charged with a felony or similar offense, that shall be a sufficient, but not a necessary, basis for such
a belief. Unless otherwise specifically provided in the Grant Notice, the foregoing definition of “Cause” shall apply for all purposes relating to the Option, notwithstanding any employment or other agreement by and between Optionee and
the Company or any Affiliate thereof that defines a termination on account of “Cause” (or a term having similar meaning). Any determination by the Board that an Optionee’s Termination of Service is for Cause may be made following a
Termination of Service and shall be communicated by written notice to Optionee within 30 days after a Termination of Service; provided, however, that after such 30-day period, the Board may make a determination that a Termination of Service is for
“Cause” based upon clear and convincing evidence subsequently received by the Board, that an event or events constituting Cause have occurred on or prior the date of the Termination of Service and, in such event, any Option Shares issued
in respect of the exercise of the Option on or after the date that the first act and/or event constituting Cause shall have occurred, shall be deemed to have been issued in respect of an expired option and shall thereupon be deemed null and void ab
initio, and Optionee shall have no claims to, or rights in, any such Option Shares. 
 (e) Notwithstanding the foregoing, the Option is
subject to earlier termination upon a Change in Control, as provided in Section 3(b) above and in Section 11 of the Plan, or upon the dissolution of the Company. If the Option will terminate in connection with a Change in Control, the
Company shall provide written notice to Optionee of a proposed transaction constituting a Change in Control, not less than ten (10) days prior to the anticipated effective date of the proposed transaction. 

(f) Notwithstanding anything herein to the contrary, no portion of any Option which is not exercisable by Optionee upon the Termination of
Service of such Optionee shall thereafter become exercisable, regardless of the reason for such termination, except as may otherwise be specifically provided in this Option Agreement or any other agreement between Optionee and the Company which has
been approved by the Board. 

  
 4 

 7. No Right to Continued Service. The Option does not confer upon Optionee any right to
continue as an Employee or Director of, or Consultant to, the Company or an Affiliate, nor does it limit in any way the right of the Company or an Affiliate to terminate Optionee’s employment or other relationship with the Company or an
Affiliate, at any time, with or without Cause. 
 8. Right of Repurchase of Option Shares. 

(a) In furtherance of, and not in limitation of Section 5, the Option Shares issued pursuant to the Option shall be subject to a right,
but not an obligation, of repurchase by the Company and/or its assignee(s) (the “Right of Repurchase”), at the price determined under Section 8(b) below, if prior to the termination of the Right of Repurchase as provided in
Section 10(d) below, a Termination of Service occurs for any reason, including as a result of Optionee’s death or Disability. Without the Company’s prior written consent, Option Shares issued by the Company shall not be transferable
by Optionee during the period during which the Right of Repurchase applies, and the Company may take such steps as it deems necessary to ensure compliance with this restriction. 

(b) The price per share at which the Company may exercise the Right of Repurchase (the “Repurchase Price”) shall be the Fair
Market Value of an Option Share on the date the Company exercises its Right of Repurchase, except as otherwise provided in an Early Exercise Stock Purchase Agreement referred to in Section 4. 

(c) The Company’s Right of Repurchase shall terminate if not exercised by written notice from the Company to Optionee within ninety
(90) days after the Termination of Service (or within 90 days after the date of exercise in the case of Option Shares purchased after the Termination of Service). If the Company exercises its Right of Repurchase, it shall give notice thereof to
Optionee within such ninety (90)-day period, and, upon receipt of such notice, Optionee shall immediately endorse and deliver to the Company the stock certificate(s) representing the Option Shares being repurchased, and the Company shall then
promptly pay, pursuant to the provisions of Section 8(d) below, the total Repurchase Price to Optionee. If the Company exercises its Right of Repurchase, it may exercise its right with respect to all or part of such Option Shares. 

(d) The Repurchase Price shall be paid first by cancellation of any obligation for accrued but unpaid interest outstanding under notes issued
by Optionee upon purchase of the Option Shares (if any), next by cancellation of principal outstanding under such notes (if any), and finally by payment in cash of the balance due. 

(e) In the event the Company does not elect to exercise its Right of Repurchase within the ninety (90)-day period, the Option Shares shall no
longer be subject to repurchase by the Company pursuant to this Section 8. 
 9. Right of First Refusal. Optionee agrees that he
or she will not sell or otherwise transfer any Option Shares (including transfer by operation of law) at any time before or after the expiration of the Right of Repurchase and prior to the termination of this Section 9 pursuant to
Section 10(d) below unless such Option Shares shall first be offered to the Company as follows: 
 (a) Optionee shall deliver a notice
(the “Notice”) to the Company, stating (i) Optionee’s bona fide intention to sell or transfer such Option Shares, to a third party purchaser in a bona fide arms length transaction, pursuant to a written agreement in
respect thereof; (ii) the number of such Option Shares to be sold or transferred; (iii) the consideration for which Optionee proposes to sell or transfer such Option Shares; (iv) the terms of payment of such consideration and any
other terms and conditions of sale; and (v) the name of the proposed purchaser or transferee.

 (b) Within sixty (60) days after receipt of the Notice, the Company may elect to purchase
any or all of the Option Shares to which the Notice refers, for the consideration per share and upon the terms and conditions specified in the Notice, except as set forth in Section 9(e) below for transfers involving non-cash consideration. If
the Company elects not to purchase all such Option Shares, the Company may assign its right to purchase the remaining Option Shares. The Company’s assignees may elect, within sixty (60) days after receipt by the Company of the Notice, to
purchase any or all Option Shares to which the Notice refers which the Company has not elected to purchase, for the consideration per share and upon the terms and conditions specified in the Notice, except as set forth in Section 9(e) below. An
election to purchase shall be made by written notice to Optionee, specifying the number of Option Shares to be purchased. If the Company and/or its assignees elect to purchase the offered Option Shares, they shall complete the purchase within ninety
(90) days after receipt by the Company of the Notice, unless a longer period is set forth in the Notice. 
 (c) If the Company and/or
its assignees do not elect to so purchase all of such offered Option Shares within such sixty (60)-day period, Optionee shall have no obligation to transfer such Option Shares to the Company and/or its assignees and Optionee shall have a period of
thirty (30) days thereafter to transfer all (but not less than all) of such Option Shares to the transferee referred to in the Notice and for the same consideration and on the other terms as set forth therein; provided, however, that prior to
any transfer of such Option Shares, the proposed transferee shall execute and deliver to the Company an agreement with the Company, in form and substance satisfactory to the Company, pursuant to which such transferee agrees to be subject to the
relevant provisions of this Option Agreement. 
 (d) In the event that such Option Shares are not transferred to the transferee referred to
in the Notice and in accordance with the terms of this Option Agreement within such 30-day period, the restrictions on transfer provided in this Section 9 shall again become applicable to the Option Shares. 

(e) If part or all of the purchase consideration specified in a Notice delivered by Optionee pursuant to this Section 9 is other than
cash or purchaser’s promissory note or other evidence of indebtedness, the Company and its assignee(s) shall have the right to purchase the Option Shares specified in the Notice for a cash price equal to the Fair Market Value of the number of
Option Shares to be so purchased by the Company and/or its assignee(s). The Fair Market Value of any Option Shares shall be as determined in good faith by the Company’s Board of Directors. 

(f) Notwithstanding anything in this Section 9 or elsewhere in this Agreement to the contrary, if at any time following the exercise of
all or a portion of this Option, the Company’s Bylaws contain provisions regarding the right of the Company to repurchase its securities from stockholders, then such provisions shall govern the rights of the Company and/or any other party to
repurchase shares of the Company’s stock from any stockholder, including the Option Shares, and the provisions of this Section 9 shall be inapplicable. Optionee agrees to be bound by all of the provisions of the Bylaws granting the Company
a right to repurchase its securities, if any. 

  
 6 

 10. Other Provisions Regarding Transfer. 

(a) Optionee, as a condition for accepting any Option Shares, shall not sell, transfer or pledge any Option Shares subject to the Right of
Repurchase described in Section 8 or the right of first refusal described in Section 9 hereof, other than in the manner expressly permitted in this Option Agreement, and any such sale, transfer or pledge of the Option Shares in violation
of this Agreement shall be void. The Company shall not be required (i) to transfer on its books any Option Shares which shall have been sold or transferred in violation of any of the provisions set forth in this Option Agreement or (ii) to
treat as the owner of such Option Shares or accord the right to vote or pay dividends to any transferee to whom such Option Shares shall have been so transferred. 

(b) Notwithstanding anything to the contrary contained herein, Optionee is under no restrictions as to the transfer by him or her of any or
all of the issued Option Shares to his or her Related Transferees (as defined herein), provided that each such Related Transferee shall first (i) execute a written consent to be bound by all of the relevant provisions of this Option Agreement
in form and substance satisfactory to the Company; and (ii) give a duplicate original of such consent to the Company. The “Related Transferees” of Optionee as used herein shall consist of Optionee’s spouse, his or her
adult lineal descendants, the adult spouses of his or her lineal descendants and trusts for the benefit of any of the foregoing, Optionee and/or his or her minor lineal descendants. In the event of any transfer by Optionee to his or her Related
Transferees of all or any part of the Option Shares (or in the event of any subsequent transfer by any such Related Transferee to another Related Transferee of Optionee), such Related Transferees shall receive and hold the Option Shares subject to
the relevant terms of this Option Agreement and Optionee’s rights and obligations hereunder as though the Option Shares were still owned by Optionee and shall together with Optionee continue to be deemed to be the “Optionee”
for purposes of this Option Agreement, including without limitation restrictions on the transfer of Option Shares. There shall be no further transfer of the Option Shares by a Related Transferee except between and among such Related Transferee, the
Optionee and other Related Transferees of Optionee, or except as permitted by this Option Agreement. The Company advises Optionee to seek independent tax counsel prior to transferring any Option Shares to any Related Transferee. 

  
 7 

 (c) Optionee hereby grants to the Company a security interest in the Option Shares for the
purpose of ensuring that a transfer in violation of the restrictions set forth in Sections 8, 9 and 10 of this Agreement does not occur. In furtherance of such security interest, the Company may, at its option, retain the certificate(s) evidencing
the Option Shares, together with stock assignments executed in blank by Optionee, until such transfer restrictions terminate in accordance with Section 10(d). Optionee hereby grants to any officer(s) of the Company the power of attorney to
cause the Option Shares to be transferred on the books of the Company in the event the Company and/or its assignees repurchase some or all of the Option Shares in accordance with this Option Agreement. 

(d) The transfer restrictions provided in Sections 8, 9 and 10 hereof may be terminated on such conditions as the Board may determine in its
sole discretion. 
 11. Notice of Tax Election. If Optionee makes any tax election relating to the treatment of the Option Shares
under the Internal Revenue Code of 1986, as amended, Optionee shall promptly notify the Company of such election. 
 12. Market
Stand-Off. 
 (a) By Optionee exercising his or her Option, Optionee agrees not to sell, dispose of, transfer, make any short sale of,
grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any shares of Common Stock or other securities of the Company held by Optionee, for a period of one hundred eighty
(180) days following the effective date of a registration statement of the Company filed under the Securities Act or such longer period as necessary to permit compliance with NASD Rule 2711 and similar or successor regulatory rules and
regulations (the “Lock-Up Period”); provided, however, that nothing contained in this section shall prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock-Up Period. Optionee further agrees to
execute and deliver such other agreements as may be reasonably requested by the Company and/or the underwriter(s) that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to Optionee’s shares of Common Stock until the end of such period. The underwriters of the Company’s stock are intended third party beneficiaries of this
Section 12(a) and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 
 (b)
In order to enforce the provisions of this Section 12, the Company may impose stop-transfer instructions with respect to the Option Shares until the end of the applicable Lock-Up Period. 

13. Acknowledgments of Optionee. Optionee acknowledges and agrees that: 

(a) Although the Company has made a good faith attempt to qualify the Option as an incentive stock option within the meaning of Sections 421,
422 and 424 of the Code (if the Grant Notice provides that the Option is an Incentive Stock Option), the Company does not warrant that the Option granted herein constitutes an “incentive stock option” within the meaning of such
sections, or that the transfer of Option Shares will be treated for federal income tax purposes as specified in Section 421 of the Code. 

  
 8 

 (b) In the event the Option is not an incentive stock option within the meaning of Sections 421,
422 and 424 of the Code (whether or not the Grant Notice provides that the Option is an Incentive Stock Option) and it is determined that the per share Exercise Price of the Option (as set forth in the Notice of Grant of Option) is less than the
fair market value of a share of the Company’s Common Stock as of the date of grant of the Option, Optionee could have deferred compensation pursuant to Section 409A of the Code in an amount equal to the difference between the fair market
value of a share of the Company’s Common Stock as of the date that the Option vests and the per share Exercise Price multiplied by the number of Option Shares then vesting (the “spread”). As a result, because the Option likely will
not be compliant with the rules in respect of deferred compensation under Section 409A, Optionee could have taxable income (taxed at ordinary income tax rates) in an amount equal to the spread on each vesting date. Optionee would also incur a
tax equal to 20% of the spread (and to the extent that Optionee is a California resident, Optionee could incur an additional tax equal to 20% of the spread). The Company does not warrant that the Exercise Price of the Option is equal to or greater
than the fair market value of the Common Stock as of the date of grant. Because the issues relating to Section 409A are complex, the Company recommends that Optionee consult with his or her tax advisors as to the possible tax consequences
arising from the grant of the Option. 
 (c) Optionee shall notify the Company in writing within fifteen (15) days of each disposition
(including a sale, exchange, gift or a transfer of legal title) of the Option Shares made within three years after the issuance of such Option Shares. 

(d) If the Grant Notice provides that the Option is an Incentive Stock Option, Optionee understands that if, among other things, he or she
disposes of any Option Shares granted within two years of the granting of the Option to him or her or within one year of the issuance of such shares to him or her, then such Option Shares will not qualify for the beneficial treatment which Optionee
might otherwise receive under Sections 421 and 422 of the Code. 
 (e) Optionee and his or her transferees shall have no rights as a
shareholder with respect to any Option Shares until the date of the issuance of a stock certificate evidencing such Option Shares. No adjustment shall be made for dividends (ordinary or extraordinary, whether in cash, securities or other property)
or distributions or other rights for which the record date is prior to the date such stock certificate is issued, except as provided in Section 10 of the Plan. 

(f) All certificates representing the Option Shares shall have endorsed thereon the following legends, the provisions of which are hereby
incorporated into this Option Agreement by this reference, and such other legends as the Company deems necessary or appropriate: 
 THE
SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES 

  
 9 

 
LAWS OF ANY STATE AND HAVE BEEN ISSUED AND SOLD PURSUANT TO AN EXEMPTION FROM THE ACT AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED BY THE HOLDERS THEREOF AT ANY TIME EXCEPT
(1) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT FILED UNDER THE ACT COVERING THE SECURITIES, OR (2) IF, IN THE REASONABLE OPINION OF COUNSEL TO THE CORPORATION, SUCH SHARES MAY BE TRANSFERRED WITHOUT SUCH REGISTRATION. 

IN ADDITION, THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A RIGHT OF REPURCHASE AND RIGHT OF FIRST REFUSAL OPTION IN FAVOR OF
THE CORPORATION, AND THE SALE, TRANSFER OR HYPOTHECATION OF THE SECURITIES REPRESENTED HEREBY IS RESTRICTED BY THE PROVISIONS OF A STOCK OPTION AGREEMENT ENTERED INTO BY THE CORPORATION AND THIS STOCKHOLDER, A COPY OF WHICH IS ON FILE AT THE
PRINCIPAL OFFICE OF THE CORPORATION AND ALL OF THE PROVISIONS OF WHICH ARE INCORPORATED HEREIN. 
 14. Investment Representations. As
an inducement to the Company to grant the Option and issue the Option Shares to Optionee, Optionee hereby makes the following representations and warranties, and authorizes the Company to rely upon the same: 

(a) Optionee will acquire the Option Shares for investment for his or her own account, not for resale, without any intention of or view toward
or for participating, directly or indirectly, in a distribution of the Option Shares or any portion thereof. 
 (b) Optionee understands
that an investment in the Company is speculative, that any possible profits therefrom are uncertain, and that he or she must bear the economic risks of the investment in the Company for an indefinite period of time. 

(c) Optionee understands that the Option Shares have not been registered under the Securities Act in reliance on the exemption provided by
Rule 701 promulgated thereunder for compensatory benefit plans; and that the Option Shares have not been registered or qualified under the “blue sky” laws of any state. 

(d) Optionee understands that the Option Shares may have to be held indefinitely unless they are subsequently registered under the Securities
Act and qualified or registered under other applicable securities laws, rules and regulations, which is unlikely, or unless an exemption from such qualification or registration is available. 

  
 10 

 (e) Optionee understands and agrees that (i) the legends set forth in Section 13(f)
hereof will be placed on the certificate(s) evidencing the Option Shares and, except as otherwise herein provided for, on certificate(s) issued to transferees; (ii) the stock records of the Company will be noted with respect to such
restrictions; (iii) the Company will not be under any obligation to register the Option Shares or to comply with any exemption available for sale of the Option Shares without registration; and (iv) the information or conditions necessary
to permit routine sales of securities of the Company under Rule 144 of the Securities Act are not now available and it is not likely that they will become available in the foreseeable future. 

(f) Optionee is a bona fide resident and domiciliary of, not a temporary transient resident of, and has his or her principal residence in, the
state or other jurisdiction set forth under Optionee’s signature in the Grant Notice, and Optionee does not have any present intention of moving his or her principal residence from such state or jurisdiction. 

15. Withholding Obligations. Whenever Option Shares are to be issued under the Option Agreement, the Company shall have the right to
require Optionee to remit to the Company an amount sufficient to satisfy federal, state and local withholding tax requirements prior to issuance and/or delivery of any certificate or certificates for such Option Shares. 

16. No Obligation to Notify. The Company shall have no duty or obligation to Optionee to advise Optionee as to the time or manner of
exercising the Option. Furthermore, except as specifically set forth herein or in the Plan, the Company shall have no duty or obligation to warn or otherwise advise Optionee of a pending termination or expiration of the Option or a possible period
in which the Option may not be exercised. The Company has no duty or obligation to minimize the tax consequences of the Option granted to Optionee. 

17. Miscellaneous. 
 (a)
This Option Agreement shall bind and inure to the benefit of the parties’ heirs, legal representatives, successors and permitted assigns. 

(b) This Option Agreement, the Grant Notice and the Plan, constitute the entire agreement between the parties pertaining to the subject matter
contained herein and they supersede all prior and contemporaneous agreements, representations and understandings of the parties. No supplement, modification or amendment of this Option Agreement shall be binding unless executed in writing by all of
the parties. No waiver of any of the provisions of this Option Agreement shall be deemed or shall constitute a waiver of any other provisions, whether or not similar, nor shall any waiver constitute a continuing waiver. No waiver shall be binding
unless executed in writing by the party making the waiver. In the event there exists any conflict or discrepancy between any of the terms in the Plan and this Option Agreement, the terms of the Plan shall be controlling. A copy of the Plan has been
delivered to Optionee and also may be inspected by Optionee at the principal office of the Company. 
 (c) By execution of the Grant Notice
and delivery of a Notice of Exercise to the Company in connection with the exercise of the Option, as provided in Section 3 above, Optionee consents to the delivery of any notice to the stockholders given by the Company in the form of an
electronic transmission, pursuant to, and as described in, Section 232 of the Delaware General Corporation Law. 

  
 11 

 (d) Should any portion of the Plan, the Grant Notice or this Option Agreement be declared invalid
and unenforceable, then such portion shall be deemed to be severable from this Option Agreement and shall not affect the remainder hereof. 

(e) All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (i) upon personal delivery to
the party to be notified; (ii) three (3) days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (iii) one (1) day after deposit with a nationally recognized overnight courier,
specifying next day delivery, with written verification of receipt. All communications shall be sent to the Company at its principal executive office, and to Optionee at the address set forth in the Option Agreement, or at such other address as the
Company or Optionee may designate by ten (10) days advance written notice to the other party hereto. 
 (f) Any dispute or claim
concerning the Option Agreement or the Plan or any disputes or claims relating to or arising out of the Option Agreement or the Plan shall be fully, finally and exclusively resolved by binding and confidential arbitration conducted pursuant to the
rules of Judicial Arbitration and Mediation Services, Inc. (“JAMS”) in the County of San Diego, California. In addition to any other relief, the arbitrator may award to the prevailing party recovery of its attorneys’ fees and
costs. By executing the Option Agreement, the Company and Optionee waive their respective rights to have any such disputes or claims tried by a judge or jury. 

(g) This Option Agreement shall be construed according to the laws of the State of California. This Option Agreement is made and entered into
in San Diego County, California.

EVERBRIDGE, INC. 

2016 EQUITY INCENTIVE PLAN 

ADOPTED BY THE BOARD OF DIRECTORS:
[        ], 2016 
 APPROVED BY THE
STOCKHOLDERS: [        ], 2016 
 EFFECTIVE
DATE: [        ], 2016 
  

	1.	GENERAL. 

 (a) Successor to and Continuation of Prior Plan. The
Plan is intended as the successor to and continuation of the Everbridge, Inc. 2011 Stock Option and Grant Plan, as amended (the “Prior Plan”). From and after 12:01 a.m. Eastern Time on the Effective Date, no additional stock
awards may be granted under the Prior Plan. All Awards granted on or after 12:01 a.m. Eastern Time on the Effective Date will be granted under this Plan. All stock awards granted under the Prior Plan will remain subject to the terms of the Prior
Plan. 
 (i) Any shares that would otherwise remain available for future grants under the Prior Plan as of 12:01 a.m. Eastern Time on
the Effective Date (the “Prior Plan’s Available Reserve”) will cease to be available under the Prior Plan at such time. Instead, that number of shares of Common Stock equal to the Prior Plan’s
Available Reserve will be added to the Share Reserve (as further described in Section 3(a) below) and be then immediately available for grants and issuance pursuant to Stock Awards hereunder, up to the maximum number set forth in
Section 3(a) below. 
 (ii) In addition, from and after 12:01 a.m. Eastern Time on the Effective Date, any shares subject to
outstanding stock awards granted under the Prior Plan that would, but for the operation of this sentence, subsequently return to the share reserve of the Prior Plan under its terms (the “Returning Shares”) will not return to
the reserve of the Prior Plan, and instead that number of shares of Common Stock equal to the Returning Shares will be added to the Share Reserve (as further described in Section 3(a) below) as and when the share becomes a Returning Share, up
to the maximum number set forth in Section 3(a) below. 
 (b) Eligible Award Recipients. Employees, Directors and Consultants
are eligible to receive Awards. 
 (c) Available Awards. The Plan provides for the grant of the following types of Awards:
(i) Incentive Stock Options, (ii) Nonstatutory Stock Options, (iii) Stock Appreciation Rights (iv) Restricted Stock Awards, (v) Restricted Stock Unit Awards, (vi) Performance Stock Awards, (vii) Performance Cash
Awards, and (viii) Other Stock Awards. 
 (d) Purpose. The Plan, through the granting of Awards, is intended to help the Company
secure and retain the services of eligible award recipients, provide incentives for such persons to exert maximum efforts for the success of the Company and any Affiliate and provide a means by which the eligible recipients may benefit from
increases in value of the Common Stock. 

  
 1. 

	2.	ADMINISTRATION. 

 (a) Administration by Board. The Board will
administer the Plan. The Board may delegate administration of the Plan to a Committee or Committees, as provided in Section 2(c). 

(b) Powers of Board. The Board will have the power, subject to, and within the limitations of, the express provisions of the Plan:

 (i) To determine (A) who will be granted Awards; (B) when and how each Award will be granted; (C) what type of
Award will be granted; (D) the provisions of each Award (which need not be identical), including when a person will be permitted to exercise or otherwise receive cash or Common Stock under the Award; (E) the number of shares of Common
Stock subject to, or the cash value of, an Award; and (F) the Fair Market Value applicable to a Stock Award. 
 (ii) To construe
and interpret the Plan and Awards granted under it, and to establish, amend and revoke rules and regulations for administration of the Plan and Awards. The Board, in the exercise of these powers, may correct any defect, omission or inconsistency in
the Plan or in any Award Agreement or in the written terms of a Performance Cash Award, in a manner and to the extent it will deem necessary or expedient to make the Plan or Award fully effective. 

(iii) To settle all controversies regarding the Plan and Awards granted under it. 

(iv) To accelerate, in whole or in part, the time at which an Award may be exercised or vest (or at which cash or shares of Common
Stock may be issued). 
 (v) To suspend or terminate the Plan at any time. Except as otherwise provided in the Plan (including
subsection (viii) below) or an Award Agreement, suspension or termination of the Plan will not impair a Participant’s rights under his or her then-outstanding Award without his or her written consent. 

(vi) To amend the Plan in any respect the Board deems necessary or advisable, including, without limitation, by adopting amendments
relating to Incentive Stock Options and certain nonqualified deferred compensation under Section 409A of the Code and/or to make the Plan or Awards granted under the Plan compliant with the requirements for Incentive Stock Options or exempt
from or compliant with the requirements for nonqualified deferred compensation under Section 409A of the Code, subject to the limitations, if any, of applicable law. However, if required by applicable law or listing requirements, and except as
provided in Section 9(a) relating to Capitalization Adjustments, the Company will seek stockholder approval of any amendment of the Plan that (A) materially increases the number of shares of Common Stock available for issuance under the
Plan, (B) materially expands the class of individuals eligible to receive Awards under the Plan, (C) materially increases the benefits accruing to Participants under the Plan, (D) materially reduces the price at which shares of Common
Stock may be issued or purchased under the Plan, (E) materially extends the term of the Plan, or (F) materially expands the types of Awards available for issuance under the Plan. 

  
 2. 

 (vii) To submit any amendment to the Plan for stockholder approval, including, but not
limited to, amendments to the Plan intended to satisfy the requirements of (A) Section 162(m) of the Code regarding the exclusion of performance-based compensation from the limit on corporate deductibility of compensation paid to Covered
Employees, (B) Section 422 of the Code regarding incentive stock options or (C) Rule 16b-3. 
 (viii) To approve forms
of Award Agreements for use under the Plan and to amend the terms of any one or more Awards, including, but not limited to, amendments to provide terms more favorable to the Participant than previously provided in the Award Agreement, subject to any
specified limits in the Plan that are not subject to Board discretion; provided however, that a Participant’s rights under any Award will not be impaired by any such amendment unless (A) the Company requests the consent of the
affected Participant, and (B) such Participant consents in writing. Notwithstanding the foregoing, (1) a Participant’s rights will not be deemed to have been impaired by any such amendment if the Board, in its sole discretion,
determines that the amendment, taken as a whole, does not materially impair the Participant’s rights, and (2) subject to the limitations of applicable law, if any, the Board may amend the terms of any one or more Awards without the
affected Participant’s consent (A) to maintain the qualified status of the Award as an Incentive Stock Option under Section 422 of the Code; (B) to change the terms of an Incentive Stock Option, if such change results in
impairment of the Award solely because it impairs the qualified status of the Award as an Incentive Stock Option under Section 422 of the Code; (C) to clarify the manner of exemption from, or to bring the Award into compliance with,
Section 409A of the Code; or (D) to comply with other applicable laws or listing requirements. 
 (ix) Generally, to
exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the Company and that are not in conflict with the provisions of the Plan or Awards. 

(x) To adopt such procedures and sub-plans as are necessary or appropriate to permit participation in the Plan by Employees, Directors
or Consultants who are foreign nationals or employed outside the United States (provided that Board approval will not be necessary for immaterial modifications to the Plan or any Award Agreement that are required for compliance with the laws of the
relevant foreign jurisdiction). 
 (xi) To effect, with the consent of any adversely affected Participant, (A) the reduction of
the exercise, purchase or strike price of any outstanding Stock Award; (B) the cancellation of any outstanding Stock Award and the grant in substitution therefor of a new (1) Option or SAR, (2) Restricted Stock Award,
(3) Restricted Stock Unit Award, (4) Other Stock Award, (5) cash and/or (6) other valuable consideration determined by the Board, in its sole discretion, with any such substituted award (x) covering the same or a different
number of shares of Common Stock as the cancelled Stock Award and (y) granted under the Plan or another equity or compensatory plan of the Company; or (C) any other action that is treated as a repricing under generally accepted accounting
principles. 

  
 3. 

 (c) Delegation to Committee. 

(i) General. The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If administration of
the Plan is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to delegate to a
subcommittee of the Committee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board will thereafter be construed as being to the Committee or subcommittee). Any delegation of
administrative powers will be reflected in resolutions, not inconsistent with the provisions of the Plan, adopted from time to time by the Board or Committee (as applicable). The Committee may, at any time, abolish the subcommittee and/or revest in
the Committee any powers delegated to the subcommittee. The Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board some or all of the powers previously delegated. 

(ii) Section 162(m) and Rule 16b-3 Compliance. The Committee may consist solely of two or more Outside Directors, in accordance
with Section 162(m) of the Code, or solely of two or more Non-Employee Directors, in accordance with Rule 16b-3. 
 (d)
Delegation to an Officer. The Board may delegate to one or more Officers the authority to do one or both of the following: (i) designate Employees who are not Officers to be recipients of Options and SARs (and, to the extent
permitted by applicable law, other Stock Awards) and, to the extent permitted by applicable law, the terms of such Awards, and (ii) determine the number of shares of Common Stock to be subject to such Stock Awards granted to such Employees;
provided, however, that the Board resolutions regarding such delegation will specify the total number of shares of Common Stock that may be subject to the Stock Awards granted by such Officer and that such Officer may not grant a Stock Award
to himself or herself. Any such Stock Awards will be granted on the form of Award Agreement most recently approved for use by the Committee or the Board, unless otherwise provided in the resolutions approving the delegation authority. The Board may
not delegate authority to an Officer who is acting solely in the capacity of an Officer (and not also as a Director) to determine the Fair Market Value pursuant to Section 13(y)(iii) below. 

(e) Effect of Board’s Decision. All determinations, interpretations and constructions made by the Board in good faith will not be
subject to review by any person and will be final, binding and conclusive on all persons. 
  

	3.	SHARES SUBJECT TO THE PLAN. 

(a) Share Reserve. Subject to Section 9(a) relating to Capitalization Adjustments, and the following sentence regarding the annual
increase, the aggregate number of shares of Common Stock that may be issued pursuant to Stock Awards will not exceed 3,893,118 shares (the “Share Reserve”), which number is the sum of (i) 2,000,000 new shares,
plus (ii) the number of shares subject to the Prior Plan’s Available Reserve, in an amount not to exceed 42,934 shares, plus (iii) the number of shares that are Returning Shares, as such shares become available from time
to time, in an amount not to exceed 1,850,184 shares. In addition, the Share 

  
 4. 

 
Reserve will automatically increase on January 1st of each year, for a period of not more than ten years, commencing on January 1st of the year following the year in which the IPO Date occurs and ending on (and including) January 1, 2025, in an amount equal to 3% of the total number of shares of Common Stock outstanding on
December 31st of the preceding calendar year. Notwithstanding the foregoing, the Board may act prior to January 1st of a given year to provide that there will be no January 1st increase in the Share Reserve for such year or that the increase in the Share Reserve for such year will be a lesser number of shares of Common Stock than would otherwise occur pursuant to the
preceding sentence. Notwithstanding the foregoing, the Board may act prior to January 1st of a given year to provide that there will be no January 1st increase in the Share Reserve for such year or that the increase in the Share Reserve
for such year will be a lesser number of shares of Common Stock than would otherwise occur pursuant to the preceding sentence. 
 For
clarity, the Share Reserve in this Section 3(a) is a limitation on the number of shares of Common Stock that may be issued pursuant to the Plan. Accordingly, this Section 3(a) does not limit the granting of Stock Awards except as provided
in Section 7(a). Shares may be issued in connection with a merger or acquisition as permitted by NASDAQ Listing Rule 5635(c) or, if applicable, NYSE Listed Company Manual Section 303A.08, AMEX Company Guide Section 711 or other
applicable rule, and such issuance will not reduce the number of shares available for issuance under the Plan. 
 (b) Reversion of Shares
to the Share Reserve. If a Stock Award or any portion thereof (i) expires or otherwise terminates without all of the shares covered by such Stock Award having been issued or (ii) is settled in cash (i.e., the
Participant receives cash rather than stock), such expiration, termination or settlement will not reduce (or otherwise offset) the number of shares of Common Stock that may be available for issuance under the Plan. If any shares of Common Stock
issued pursuant to a Stock Award are forfeited back to or repurchased by the Company because of the failure to meet a contingency or condition required to vest such shares in the Participant, then the shares that are forfeited or repurchased will
revert to and again become available for issuance under the Plan. Any shares reacquired by the Company in satisfaction of tax withholding obligations on a Stock Award or as consideration for the exercise or purchase price of a Stock Award will again
become available for issuance under the Plan. 
 (c) Incentive Stock Option Limit. Subject to the Share Reserve and
Section 9(a) relating to Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options will be 6,000,000 shares of Common Stock. 

(d) Section 162(m) Limitations. Subject to the Share Reserve and Section 9(a) relating to Capitalization Adjustments, at such
time as the Company may be subject to the applicable provisions of Section 162(m) of the Code, the following limitations will apply. 

(i) A maximum of 400,000 shares of Common Stock subject to Options, SARs and Other Stock Awards whose value is determined by reference
to an increase over an exercise or strike price of at least 100% of the Fair Market Value on the date any such Stock Award is granted may be granted to any Participant during any calendar year. 

  
 5. 

 (ii) A maximum of 250,000 shares of Common Stock subject to Performance Stock Awards may
be granted to any one Participant during any one calendar year (whether the grant, vesting or exercise is contingent upon the attainment during the Performance Period of the Performance Goals). 

(iii) A maximum of $500,000 may be granted as a Performance Cash Award to any one Participant during any one calendar year. 

If a Performance Stock Award is in the form of an Option, it will count only against the Performance Stock Award limit. If a Performance Stock
Award could be paid out in cash, it will count only against the Performance Stock Award limit. 
 (e) Limitation on Grants to
Non-Employee Directors. The maximum number of shares of Common Stock subject to Stock Awards granted under the Plan or otherwise during any one fiscal year to any Non-Employee Director, taken together with any cash fees paid by the Company to
such Non-Employee Director during such fiscal year for service as a Non-Employee Director, will not exceed $250,000 in total value (calculating the value of any such Stock Awards based on the grant date fair value of such Stock Awards for financial
reporting purposes). The Board may make exceptions to the limit in this Section 3(e) for individual Non-Employee Directors in such extraordinary circumstances (for example, to compensate such individual for interim service in the capacity of an
officer of the Company) as the Board may determine in its discretion, provided that the Non-Employee Director receiving such additional compensation may not participate in the decision to award such compensation. 

(f) Source of Shares. The stock issuable under the Plan will be shares of authorized but unissued or reacquired Common Stock, including
shares repurchased by the Company on the open market or otherwise. 
  

	4.	ELIGIBILITY. 

 (a) Eligibility for Specific Stock Awards. Incentive
Stock Options may be granted only to employees of the Company or a “parent corporation” or “subsidiary corporation” thereof (as such terms are defined in Sections 424(e) and 424(f) of the Code). Stock Awards other than Incentive
Stock Options may be granted to Employees, Directors and Consultants; provided, however, that Stock Awards may not be granted to Employees, Directors and Consultants who are providing Continuous Service only to any “parent” of the Company,
as such term is defined in Rule 405, unless (i) the stock underlying such Stock Awards is treated as “service recipient stock” under Section 409A of the Code (for example, because the Stock Awards are granted pursuant to a
Transaction such as a spin off transaction), (ii) the Company, in consultation with its legal counsel, has determined that such Stock Awards are otherwise exempt from Section 409A of the Code, or (iii) the Company, in consultation
with its legal counsel, has determined that such Stock Awards comply with the distribution requirements of Section 409A of the Code. 

(b) Ten Percent Stockholders. A Ten Percent Stockholder will not be granted an Incentive Stock Option unless the exercise price of such
Option is at least 110% of the Fair Market Value on the date of grant and the Option is not exercisable after the expiration of five years from the date of grant. 

  
 6. 

	5.	PROVISIONS RELATING TO OPTIONS AND STOCK APPRECIATION RIGHTS. 

Each Option or SAR will be in such form and will contain such terms and conditions as the Board deems appropriate. All Options will be
separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or certificates will be issued for shares of Common Stock purchased on exercise of each type of
Option. If an Option is not specifically designated as an Incentive Stock Option, or if an Option is designated as an Incentive Stock Option but some portion or all of the Option fails to qualify as an Incentive Stock Option under the applicable
rules, then the Option (or portion thereof) will be a Nonstatutory Stock Option. The provisions of separate Options or SARs need not be identical; provided, however, that each Award Agreement will conform to (through incorporation of
provisions hereof by reference in the applicable Award Agreement or otherwise) the substance of each of the following provisions: 
 (a)
Term. Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders, no Option or SAR will be exercisable after the expiration of ten years from the date of its grant or such shorter period specified in the Award
Agreement. 
 (b) Exercise Price. Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders, the
exercise or strike price of each Option or SAR will be not less than 100% of the Fair Market Value of the Common Stock subject to the Option or SAR on the date the Award is granted. Notwithstanding the foregoing, an Option or SAR may be granted with
an exercise or strike price lower than 100% of the Fair Market Value of the Common Stock subject to the Award if such Award is granted pursuant to an assumption of or substitution for another option or stock appreciation right pursuant to a
Transaction and in a manner consistent with the provisions of Section 409A of the Code and, if applicable, Section 424(a) of the Code. Each SAR will be denominated in shares of Common Stock equivalents. 

(c) Purchase Price for Options. The purchase price of Common Stock acquired pursuant to the exercise of an Option may be paid, to the
extent permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board will have the authority to grant Options that do not permit all of the following
methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to use a particular method of payment. The permitted methods of payment are as follows: 

(i) by cash, check, bank draft or money order payable to the Company; 

(ii) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of the
stock subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds; 

(iii) by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock; 

  
 7. 

 (iv) if an Option is a Nonstatutory Stock Option, by a “net exercise”
arrangement pursuant to which the Company will reduce the number of shares of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; provided,
however, that the Company will accept a cash or other payment from the Participant to the extent of any remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued. Shares of
Common Stock will no longer be subject to an Option and will not be exercisable thereafter to the extent that (A) shares issuable upon exercise are used to pay the exercise price pursuant to the “net exercise,” (B) shares are
delivered to the Participant as a result of such exercise, and (C) shares are withheld to satisfy tax withholding obligations; or 

(v) in any other form of legal consideration that may be acceptable to the Board and specified in the applicable Award Agreement. 

(d) Exercise and Payment of a SAR. To exercise any outstanding SAR, the Participant must provide written notice of exercise to the
Company in compliance with the provisions of the Award Agreement evidencing such SAR. The appreciation distribution payable on the exercise of a SAR will be not greater than an amount equal to the excess of (A) the aggregate Fair Market Value
(on the date of the exercise of the SAR) of a number of shares of Common Stock equal to the number of Common Stock equivalents in which the Participant is vested under such SAR, and with respect to which the Participant is exercising the SAR on such
date, over (B) the aggregate strike price of the number of Common Stock equivalents with respect to which the Participant is exercising the SAR on such date. The appreciation distribution may be paid in Common Stock, in cash, in any combination
of the two or in any other form of consideration, as determined by the Board and contained in the Award Agreement evidencing such SAR. 

(e) Transferability of Options and SARs. The Board may, in its sole discretion, impose such limitations on the transferability of
Options and SARs as the Board will determine. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of Options and SARs will apply: 

(i) Restrictions on Transfer. An Option or SAR will not be transferable except by will or by the laws of descent and distribution (and
pursuant to subsections (ii) and (iii) below), and will be exercisable during the lifetime of the Participant only by the Participant. The Board may permit transfer of the Option or SAR in a manner that is not prohibited by applicable tax
and securities laws. Except as explicitly provided herein, neither an Option nor a SAR may be transferred for consideration. 
 (ii)
Domestic Relations Orders. Subject to the approval of the Board or a duly authorized Officer, an Option or SAR may be transferred pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or
separation instrument as permitted by Treasury Regulation 1.421-1(b)(2). If an Option is an Incentive Stock Option, such Option may be deemed to be a Nonstatutory Stock Option as a result of such transfer. 

(iii) Beneficiary Designation. Subject to the approval of the Board or a duly authorized Officer, a Participant may, by delivering
written notice to the Company, in a form approved by the Company (or the designated broker), designate a third party who, upon the death 

  
 8. 

 
of the Participant, will thereafter be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. In the absence of such a
designation, upon the death or the Participant, the executor or administrator of the Participant’s estate will be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. However,
the Company may prohibit designation of a beneficiary at any time, including due to any conclusion by the Company that such designation would be inconsistent with the provisions of applicable laws. 

(f) Vesting Generally. The total number of shares of Common Stock subject to an Option or SAR may vest and therefore become exercisable
in periodic installments that may or may not be equal. The Option or SAR may be subject to such other terms and conditions on the time or times when it may or may not be exercised (which may be based on the satisfaction of Performance Goals or other
criteria) as the Board may deem appropriate. The vesting provisions of individual Options or SARs may vary. The provisions of this Section 5(f) are subject to any Option or SAR provisions governing the minimum number of shares of Common Stock
as to which an Option or SAR may be exercised. 
 (g) Termination of Continuous Service. Except as otherwise provided in the
applicable Award Agreement or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates (other than for Cause and other than upon the Participant’s death or Disability), the Participant may
exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Award as of the date of termination of Continuous Service) within the period of time ending on the earlier of (i) the date three months
following the termination of the Participant’s Continuous Service (or such longer or shorter period specified in the applicable Award Agreement) and (ii) the expiration of the term of the Option or SAR as set forth in the Award Agreement.
If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR (as applicable) within the applicable time frame, the Option or SAR will terminate. 

(h) Extension of Termination Date. Except as otherwise provided in the applicable Award Agreement or other agreement between the
Participant and the Company, if the exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause and other than upon the Participant’s death or Disability) would be prohibited at any
time solely because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act, then the Option or SAR will terminate on the earlier of (i) the expiration of a total period of time (that need not
be consecutive) equal to the applicable post termination exercise period after the termination of the Participant’s Continuous Service during which the exercise of the Option or SAR would not be in violation of such registration requirements,
and (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement. In addition, unless otherwise provided in a Participant’s Award Agreement, if the sale of any Common Stock received on exercise of an
Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause) would violate the Company’s insider trading policy, then the Option or SAR will terminate on the earlier of (i) the expiration of a
period of months (that need not be consecutive) equal to the applicable post-termination exercise period after the termination of the Participant’s Continuous Service during which the sale of the Common Stock received upon exercise of the
Option or SAR would not be in violation of the Company’s insider trading policy, or (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement. 

  
 9. 

 (i) Disability of Participant. Except as otherwise provided in the applicable Award
Agreement or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates as a result of the Participant’s Disability, the Participant may exercise his or her Option or SAR (to the extent that
the Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such period of time ending on the earlier of (i) the date 12 months following such termination of Continuous
Service (or such longer or shorter period specified in the Award Agreement) and (ii) the expiration of the term of the Option or SAR as set forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not
exercise his or her Option or SAR within the applicable time frame, the Option or SAR (as applicable) will terminate. 
 (j) Death of
Participant. Except as otherwise provided in the applicable Award Agreement or other agreement between the Participant and the Company, if (i) a Participant’s Continuous Service terminates as a result of the Participant’s death,
or (ii) the Participant dies within the period (if any) specified in the Award Agreement for exercisability after the termination of the Participant’s Continuous Service for a reason other than death, then the Option or SAR may be
exercised (to the extent the Participant was entitled to exercise such Option or SAR as of the date of death) by the Participant’s estate, by a person who acquired the right to exercise the Option or SAR by bequest or inheritance or by a person
designated to exercise the Option or SAR upon the Participant’s death, but only within the period ending on the earlier of (i) the date 18 months following the date of death (or such longer or shorter period specified in the Award
Agreement) and (ii) the expiration of the term of such Option or SAR as set forth in the Award Agreement. If, after the Participant’s death, the Option or SAR is not exercised within the applicable time frame, the Option or SAR (as
applicable) will terminate. 
 (k) Termination for Cause. Except as explicitly provided otherwise in a Participant’s Award
Agreement or other individual written agreement between the Company or any Affiliate and the Participant, if a Participant’s Continuous Service is terminated for Cause, the Option or SAR will terminate immediately upon such Participant’s
termination of Continuous Service, and the Participant will be prohibited from exercising his or her Option or SAR from and after the time of such termination of Continuous Service. If a Participant’s Continuous Service is suspended pending an
investigation of the existence of Cause, all of the Participant’s rights under the Option or SAR will also be suspended during the investigation period. 

(l) Non-Exempt Employees. If an Option or SAR is granted to an Employee who is a non-exempt employee for purposes of the Fair Labor
Standards Act of 1938, as amended, the Option or SAR will not be first exercisable for any shares of Common Stock until at least six months following the date of grant of the Option or SAR (although the Award may vest prior to such date).
Consistent with the provisions of the Worker Economic Opportunity Act, (i) if such non-exempt Employee dies or suffers a Disability, (ii) upon a Corporate Transaction in which such Option or SAR is not assumed, continued, or substituted,
(iii) upon a Change in Control, or (iv) upon the Participant’s retirement (as such term may be defined in the Participant’s Award Agreement, in another agreement between the Participant and the Company, or, if no such 

  
 10. 

 
definition, in accordance with the Company’s then current employment policies and guidelines), the vested portion of any Options and SARs may be exercised earlier than six months
following the date of grant. The foregoing provision is intended to operate so that any income derived by a non-exempt employee in connection with the exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay. To the
extent permitted and/or required for compliance with the Worker Economic Opportunity Act to ensure that any income derived by a non-exempt employee in connection with the exercise, vesting or issuance of any shares under any other Stock Award will
be exempt from the employee’s regular rate of pay, the provisions of this Section 5(l) will apply to all Stock Awards and are hereby incorporated by reference into such Stock Award Agreements. 

 

	6.	PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS AND SARS. 

(a) Restricted Stock Awards. Each Restricted Stock Award Agreement will be in such form and will contain such terms and conditions as
the Board deems appropriate. To the extent consistent with the Company’s bylaws, at the Board’s election, shares of Common Stock may be (i) held in book entry form subject to the Company’s instructions until any restrictions
relating to the Restricted Stock Award lapse; or (ii) evidenced by a certificate, which certificate will be held in such form and manner as determined by the Board. The terms and conditions of Restricted Stock Award Agreements may change from
time to time, and the terms and conditions of separate Restricted Stock Award Agreements need not be identical. Each Restricted Stock Award Agreement will conform to (through incorporation of the provisions hereof by reference in the agreement or
otherwise) the substance of each of the following provisions: 
 (i) Consideration. A Restricted Stock Award may be awarded in
consideration for (A) cash, check, bank draft or money order payable to the Company, (B) past services to the Company or an Affiliate, or (C) any other form of legal consideration (including future services) that may be acceptable to
the Board, in its sole discretion, and permissible under applicable law. 
 (ii) Vesting. Shares of Common Stock awarded under the
Restricted Stock Award Agreement may be subject to forfeiture to the Company in accordance with a vesting schedule to be determined by the Board. 

(iii) Termination of Participant’s Continuous Service. If a Participant’s Continuous Service terminates, the Company may
receive through a forfeiture condition or a repurchase right any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination of Continuous Service under the terms of the Restricted Stock Award
Agreement. 
 (iv) Transferability. Rights to acquire shares of Common Stock under the Restricted Stock Award Agreement will be
transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board will determine in its sole discretion, so long as Common Stock awarded under the Restricted Stock Award
Agreement remains subject to the terms of the Restricted Stock Award Agreement. 

  
 11. 

 (v) Dividends. A Restricted Stock Award Agreement may provide that any dividends paid on
Restricted Stock will be subject to the same vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate. 

(b) Restricted Stock Unit Awards. Each Restricted Stock Unit Award Agreement will be in such form and will contain such terms and
conditions as the Board deems appropriate. The terms and conditions of Restricted Stock Unit Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Unit Award Agreements need not be identical. Each
Restricted Stock Unit Award Agreement will conform to (through incorporation of the provisions hereof by reference in the Agreement or otherwise) the substance of each of the following provisions: 

(i) Consideration. At the time of grant of a Restricted Stock Unit Award, the Board will determine the consideration, if any, to be paid
by the Participant upon delivery of each share of Common Stock subject to the Restricted Stock Unit Award. The consideration to be paid (if any) by the Participant for each share of Common Stock subject to a Restricted Stock Unit Award may be paid
in any form of legal consideration that may be acceptable to the Board, in its sole discretion, and permissible under applicable law. 

(ii) Vesting. At the time of the grant of a Restricted Stock Unit Award, the Board may impose such restrictions on or conditions to the
vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate. 
 (iii) Payment. A Restricted
Stock Unit Award may be settled by the delivery of shares of Common Stock, their cash equivalent, any combination thereof or in any other form of consideration, as determined by the Board and contained in the Restricted Stock Unit Award Agreement.

 (iv) Additional Restrictions. At the time of the grant of a Restricted Stock Unit Award, the Board, as it deems appropriate, may
impose such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the vesting of such Restricted Stock Unit Award. 

(v) Dividend Equivalents. Dividend equivalents may be credited in respect of shares of Common Stock covered by a Restricted Stock Unit
Award, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Board, such dividend equivalents may be converted into additional shares of Common Stock covered by the Restricted Stock Unit
Award in such manner as determined by the Board. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be subject to all of the same terms and conditions of the underlying Restricted
Stock Unit Award Agreement to which they relate. 
 (vi) Termination of Participant’s Continuous Service. Except as otherwise
provided in the applicable Restricted Stock Unit Award Agreement, such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon the Participant’s termination of Continuous Service. 

  
 12. 

 (c) Performance Awards. 

(i) Performance Stock Awards. A Performance Stock Award is a Stock Award (covering a number of shares not in excess of that set forth
in Section 3(d)(ii) above) that is payable (including that may be granted, vest or exercised) contingent upon the attainment during a Performance Period of certain Performance Goals. A Performance Stock Award may, but need not, require the
completion of a specified period of Continuous Service. The length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree such Performance Goals have been attained
will be conclusively determined by the Committee (or, if not required for compliance with Section 162(m) of the Code, the Board), in its sole discretion. In addition, to the extent permitted by applicable law and the applicable Award Agreement,
the Board may determine that cash may be used in payment of Performance Stock Awards. 
 (ii) Performance Cash Awards. A Performance
Cash Award is a cash award (for a dollar value not in excess of that set forth in Section 3(d)(iii) above) that is payable contingent upon the attainment during a Performance Period of certain Performance Goals. A Performance Cash Award may
also require the completion of a specified period of Continuous Service. At the time of grant of a Performance Cash Award, the length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of
whether and to what degree such Performance Goals have been attained will be conclusively determined by the Committee (or, if not required for compliance with Section 162(m) of the Code, the Board), in its sole discretion. The Board may specify
the form of payment of Performance Cash Awards, which may be cash or other property, or may provide for a Participant to have the option for his or her Performance Cash Award, or such portion thereof as the Board may specify, to be paid in whole or
in part in cash or other property. 
 (iii) Board Discretion. The Board retains the discretion to reduce or eliminate the
compensation or economic benefit due upon attainment of Performance Goals and to define the manner of calculating the Performance Criteria it selects to use for a Performance Period. 

(iv) Section 162(m) Compliance. Unless otherwise permitted in compliance with the requirements of Section 162(m) of the Code
with respect to an Award intended to qualify as “performance-based compensation” thereunder, the Committee will establish the Performance Goals applicable to, and the formula for calculating the amount payable under, the Award no later
than the earlier of (A) the date 90 days after the commencement of the applicable Performance Period, and (B) the date on which 25% of the Performance Period has elapsed, and in any event at a time when the achievement of the applicable
Performance Goals remains substantially uncertain. Prior to the payment of any compensation under an Award intended to qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee will certify the extent
to which any Performance Goals and any other material terms under such Award have been satisfied (other than in cases where the Performance Goals relate solely to the increase in the value of the Common Stock). Notwithstanding satisfaction of any
completion of any Performance Goals, the number of shares of Common Stock, Options, cash or other benefits granted, issued, retainable and/or vested under an Award on account of satisfaction of such Performance Goals may be reduced by the Committee
on the basis of such further considerations as the Committee, in its sole discretion, will determine. 

  
 13. 

 (d) Other Stock Awards. Other forms of Stock Awards valued in whole or in part by
reference to, or otherwise based on, Common Stock, including the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than 100% of the Fair Market Value of the Common Stock at the time of grant)
may be granted either alone or in addition to Stock Awards provided for under Section 5 and the preceding provisions of this Section 6. Subject to the provisions of the Plan, the Board will have sole and complete authority to determine the
persons to whom and the time or times at which such Other Stock Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to be granted pursuant to such Other Stock Awards and all other terms and conditions of
such Other Stock Awards. 
  

	7.	COVENANTS OF THE COMPANY. 

(a) Availability of Shares. The Company will keep available at all times the number of shares of Common Stock reasonably required to
satisfy then-outstanding Stock Awards. 
 (b) Securities Law Compliance. The Company will seek to obtain from each regulatory
commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise or vesting of the Stock Awards; provided, however, that
this undertaking will not require the Company to register under the Securities Act or other applicable law the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts and at a
reasonable cost, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company will be relieved
from any liability for failure to issue and sell Common Stock upon exercise of such Stock Awards unless and until such authority is obtained. A Participant will not be eligible for the grant of an Award or the subsequent issuance of cash or Common
Stock pursuant to the Award if such grant or issuance would be in violation of any applicable securities law. 
 (c) No Obligation
to Notify or Minimize Taxes. The Company will have no duty or obligation to any Participant to advise such holder as to the time or manner of exercising such Stock Award. Furthermore, the Company will have no duty or obligation to warn or
otherwise advise such holder of a pending termination or expiration of an Award or a possible period in which the Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of an Award to the holder of such
Award. 
  

	8.	MISCELLANEOUS. 

 (a) Use of Proceeds from Sales of Common Stock.
Proceeds from the sale of shares of Common Stock pursuant to Stock Awards will constitute general funds of the Company. 
 (b)
Corporate Action Constituting Grant of Awards. Corporate action constituting a grant by the Company of an Award to any Participant will be deemed completed as of the date of such corporate action, unless otherwise determined by the Board,
regardless of when the instrument, certificate, or letter evidencing the Award is communicated to, or actually 

  
 14. 

 
received or accepted by, the Participant. In the event that the corporate records (e.g., Board consents, resolutions or minutes) documenting the corporate action constituting the grant contain
terms (e.g., exercise price, vesting schedule or number of shares) that are inconsistent with those in the Award Agreement or related grant documents as a result of a clerical error in the papering of the Award Agreement or related grant documents,
the corporate records will control and the Participant will have no legally binding right to the incorrect term in the Award Agreement or related grant documents. 

(c) Stockholder Rights. No Participant will be deemed to be the holder of, or to have any of the rights of a holder with respect to,
any shares of Common Stock subject to an Award unless and until (i) such Participant has satisfied all requirements for exercise of, or the issuance of shares of Common Stock under, the Award pursuant to its terms, and (ii) the issuance of
the Common Stock subject to such Award has been entered into the books and records of the Company. 
 (d) No Employment or Other
Service Rights. Nothing in the Plan, any Award Agreement or any other instrument executed thereunder or in connection with any Award granted pursuant thereto will confer upon any Participant any right to continue to serve the Company or an
Affiliate in the capacity in effect at the time the Award was granted or will affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service
of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the bylaws of the Company or an Affiliate, and any applicable provisions of the corporate
law of the state or foreign jurisdiction in which the Company or the Affiliate is domiciled or incorporated, as the case may be. 

(e) Change in Time Commitment. In the event a Participant’s regular level of time commitment in the performance of his or her
services for the Company and any Affiliates is reduced (for example, and without limitation, if the Participant is an Employee of the Company and the Employee has a change in status from a full-time Employee to a part-time Employee or takes an
extended leave of absence) after the date of grant of any Award to the Participant, the Board has the right in its sole discretion to (x) make a corresponding reduction in the number of shares or cash amount subject to any portion of such Award
that is scheduled to vest or become payable after the date of such change in time commitment, and (y) in lieu of or in combination with such a reduction, extend the vesting or payment schedule applicable to such Award. In the event of any such
reduction, the Participant will have no right with respect to any portion of the Award that is so reduced or extended. 
 (f)
Incentive Stock Option Limitations. To the extent that the aggregate Fair Market Value (determined at the time of grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during
any calendar year (under all plans of the Company and any Affiliates) exceeds $100,000 (or such other limit established in the Code) or otherwise does not comply with the rules governing Incentive Stock Options, the Options or portions thereof that
exceed such limit (according to the order in which they were granted) or otherwise do not comply with such rules will be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s). 

  
 15. 

 (g) Investment Assurances. The Company may require a Participant, as a condition of
exercising or acquiring Common Stock under any Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative
reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the
Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Award for the Participant’s own account and not with any present intention of selling or otherwise
distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, will be inoperative if (A) the issuance of the shares upon the exercise or acquisition of Common Stock under the Stock Award has
been registered under a then currently effective registration statement under the Securities Act, or (B) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the
circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with
applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock. 
 (h)
Withholding Obligations. Unless prohibited by the terms of an Award Agreement, the Company may, in its sole discretion, satisfy any federal, state or local tax withholding obligation relating to an Award by any of the following means or by a
combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Stock Award;
provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law (or such lesser amount as may be necessary to avoid classification of the Stock Award
as a liability for financial accounting purposes); (iii) withholding cash from an Award settled in cash; (iv) withholding payment from any amounts otherwise payable to the Participant; or (v) by such other method as may be set forth
in the Award Agreement. 
 (i) Electronic Delivery. Any reference herein to a “written” agreement or document will
include any agreement or document delivered electronically, filed publicly at www.sec.gov (or any successor website thereto) or posted on the Company’s intranet (or other shared electronic medium controlled by the Company to which the
Participant has access). 
 (j) Deferrals. To the extent permitted by applicable law, the Board, in its sole discretion, may
determine that the delivery of Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may establish programs and procedures for deferral elections to be made by
Participants. Deferrals by Participants will be made in accordance with Section 409A of the Code. Consistent with Section 409A of the Code, the Board may provide for distributions while a Participant is still an employee or otherwise
providing services to the Company. The Board is authorized to make deferrals of Awards and determine when, and in what annual percentages, Participants may receive payments, including lump sum payments, following the Participant’s termination
of Continuous Service, and implement such other terms and conditions consistent with the provisions of the Plan and in accordance with applicable law. 

  
 16. 

 (k) Clawback/Recovery. All Awards granted under the Plan will be subject to recoupment in
accordance with any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the
Dodd-Frank Wall Street Reform and Consumer Protection Act or other applicable law. In addition, the Board may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Board determines necessary or appropriate,
including but not limited to a reacquisition right in respect of previously acquired shares of Common Stock or other cash or property upon the occurrence of Cause. No recovery of compensation under such a clawback policy will be an event giving rise
to a right to voluntary terminate employment upon a “resignation for good reason,” or for a “constructive termination” or any similar term under any plan of or agreement with the Company. 

(l) Compliance with Section 409A. Unless otherwise expressly provided for in an Award Agreement, the Plan and Award Agreements
will be interpreted to the greatest extent possible in a manner that makes the Plan and the Awards granted hereunder exempt from Section 409A of the Code, and, to the extent not so exempt, in compliance with Section 409A of the Code. If
the Board determines that any Award granted hereunder is not exempt from and is therefore subject to Section 409A of the Code, the Award Agreement evidencing such Award will incorporate the terms and conditions necessary to avoid the
consequences specified in Section 409A(a)(1) of the Code, and to the extent an Award Agreement is silent on terms necessary for compliance, such terms are hereby incorporated by reference into the Award Agreement. Notwithstanding anything to
the contrary in this Plan (and unless the Award Agreement specifically provides otherwise), if the shares of Common Stock are publicly traded, and if a Participant holding an Award that constitutes “deferred compensation” under
Section 409A of the Code is a “specified employee” for purposes of Section 409A of the Code, no distribution or payment of any amount that is due because of a “separation from service” (as defined in Section 409A
of the Code without regard to alternative definitions thereunder) will be issued or paid before the date that is six months following the date of such Participant’s “separation from service” or, if earlier, the date of the
Participant’s death, unless such distribution or payment can be made in a manner that complies with Section 409A of the Code, and any amounts so deferred will be paid in a lump sum on the day after such six month period elapses, with the
balance paid thereafter on the original schedule. 
  

	9.	ADJUSTMENTS UPON CHANGES IN COMMON STOCK; OTHER CORPORATE EVENTS.

 (a) Capitalization Adjustments. In the event of a Capitalization Adjustment, the Board will appropriately and
proportionately adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities that may be issued pursuant to the exercise of Incentive
Stock Options pursuant to Section 3(c), (iii) the class(es) and maximum number of securities that may be awarded to any person pursuant to Sections 3(d), and (iv) the class(es) and number of securities and price per share of stock
subject to outstanding Stock Awards. The Board will make such adjustments, and its determination will be final, binding and conclusive. 

  
 17. 

 (b) Dissolution. Except as otherwise provided in the Stock Award Agreement, in the event
of a Dissolution of the Company, all outstanding Stock Awards (other than Stock Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the Company’s right of repurchase) will terminate
immediately prior to the completion of such Dissolution, and the shares of Common Stock subject to the Company’s repurchase rights or subject to a forfeiture condition may be repurchased or reacquired by the Company notwithstanding the fact
that the holder of such Stock Award is providing Continuous Service; provided, however, that the Board may, in its sole discretion, cause some or all Stock Awards to become fully vested, exercisable and/or no longer subject to repurchase or
forfeiture (to the extent such Stock Awards have not previously expired or terminated) before the Dissolution is completed but contingent on its completion. 

(c) Transactions. The following provisions will apply to Stock Awards in the event of a Transaction unless otherwise provided in the
Stock Award Agreement or any other written agreement between the Company or any Affiliate and the Participant or unless otherwise expressly provided by the Board at the time of grant of a Stock Award. In the event of a Transaction, then,
notwithstanding any other provision of the Plan, the Board may take one or more of the following actions with respect to Stock Awards, contingent upon the closing or completion of the Transaction: 

(i) arrange for the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) to
assume or continue the Stock Award or to substitute a similar stock award for the Stock Award (including, but not limited to, an award to acquire the same consideration paid to the stockholders of the Company pursuant to the Transaction); 

(ii) arrange for the assignment of any reacquisition or repurchase rights held by the Company in respect of Common Stock issued
pursuant to the Stock Award to the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company); 

(iii) accelerate the vesting, in whole or in part, of the Stock Award (and, if applicable, the time at which the Stock Award may be
exercised) to a date prior to the effective time of such Transaction as the Board determines (or, if the Board does not determine such a date, to the date that is five days prior to the effective date of the Transaction), with such Stock Award
terminating if not exercised (if applicable) at or prior to the effective time of the Transaction; provided, however, that the Board may require Participants to complete and deliver to the Company a notice of exercise before the effective
date of a Transaction, which exercise is contingent upon the effectiveness of such Transaction; 
 (iv) arrange for the lapse, in
whole or in part, of any reacquisition or repurchase rights held by the Company with respect to the Stock Award; 
 (v) cancel or
arrange for the cancellation of the Stock Award, to the extent not vested or not exercised prior to the effective time of the Transaction, in exchange for such cash consideration or no consideration as the Board, in its sole discretion, may consider
appropriate; and 

  
 18. 

 (vi) make a payment, in such form as may be determined by the Board equal to the excess,
if any, of (A) the value of the property the Participant would have received upon the exercise of the Stock Award immediately prior to the effective time of the Transaction, over (B) any exercise price payable by such holder in connection
with such exercise. For clarity, this payment may be zero ($0) if the value of the property is equal to or less than the exercise price. Payments under this provision may be delayed to the same extent that payment of consideration to the holders of
Common Stock in connection with the Transaction is delayed as a result of escrows, earn outs, holdbacks or any other contingencies. 
 The Board need not
take the same action or actions with respect to all Stock Awards or portions thereof or with respect to all Participants. The Board may take different actions with respect to the vested and unvested portions of a Stock Award. 

(d) Change in Control. A Stock Award may be subject to additional acceleration of vesting and exercisability upon or after a Change in
Control as may be provided in the Stock Award Agreement for such Stock Award or as may be provided in any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such provision, no such acceleration
will occur. 
  

	10.	TERMINATION OR SUSPENSION OF THE PLAN. 

(a) The Board may suspend or terminate the Plan at any time. No Incentive Stock Option will be granted after the tenth anniversary of
the earlier of (i) the Adoption Date, or (ii) the date the Plan is approved by the stockholders of the Company. No Awards may be granted under the Plan while the Plan is suspended or after it is terminated. 

(b) No Impairment of Rights. Suspension or termination of the Plan will not impair rights and obligations under any Award granted while
the Plan is in effect except with the written consent of the affected Participant or as otherwise permitted in the Plan. 
  

	11.	EFFECTIVE DATE OF PLAN. 

 The
Plan will come into existence on the Adoption Date; provided, however, no Award may be granted prior to the IPO Date (that is, the Effective Date). In addition, no Stock Award will be exercised (or, in the case of a Restricted Stock Award,
Restricted Stock Unit Award, Performance Stock Award, or Other Stock Award, will be granted) and no Performance Cash Award will be settled unless and until the Plan has been approved by the stockholders of the Company, which approval will be within
12 months after the date the Plan is adopted by the Board. 
  

	12.	CHOICE OF LAW. 

 The laws of the State of
Delaware will govern all questions concerning the construction, validity and interpretation of this Plan, without regard to that state’s conflict of laws rules. 

  
 19. 

	13.	DEFINITIONS. As used in the Plan, the following definitions will apply to the capitalized terms indicated below: 

(a) “Adoption Date” means the date the Plan is adopted by the Board. 

(b) “Affiliate” means, at the time of determination, any “parent” or
“subsidiary” of the Company as such terms are defined in Rule 405. The Board will have the authority to determine the time or times at which “parent” or “subsidiary” status is determined within the foregoing
definition. 
 (c) “Award” means a Stock Award or a Performance Cash Award. 

(d) “Award Agreement” means a written agreement between the Company and a
Participant evidencing the terms and conditions of an Award. 
 (e) “Board” means the Board of
Directors of the Company. 
 (f) “Capitalization Adjustment” means any change
that is made in, or other events that occur with respect to, the Common Stock subject to the Plan or subject to any Stock Award after the Effective Date without the receipt of consideration by the Company through merger, consolidation,
reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, large nonrecurring cash dividend, stock split, reverse stock split, liquidating dividend, combination of shares, exchange of shares, change in
corporate structure or any similar equity restructuring transaction, as that term is used in Statement of Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto). Notwithstanding the foregoing, the
conversion of any convertible securities of the Company will not be treated as a Capitalization Adjustment. 

(g) “Cause” will have the meaning ascribed to such term in any written agreement
between the Participant and the Company defining such term and, in the absence of such agreement, such term means, with respect to a Participant, the occurrence of any of the following events: (i) such Participant’s commission of any act
constituting financial dishonesty against the Company or its Subsidiaries (which act would be chargeable as a crime under applicable law); (ii) such Participant’s engaging in any other act of dishonesty, fraud, intentional
misrepresentation, moral turpitude, illegality or harassment which, as determined in good faith by the Board, would: (A) materially adversely affect the business or the reputation of the Company or any of its Subsidiaries with their respective
current or prospective customers, suppliers, lenders and/or other third parties with whom such entity does or might do business; or (B) expose the Company or any of its Subsidiaries to a risk of civil or criminal legal damages, liabilities or
penalties; (iii) such Participant’s repeated failure to follow the directives of the Company’s chief executive officer or the Board, (iv) such Participant’s material misconduct, violation of the Company’s or
Subsidiaries’ policies, or willful and deliberate non-performance of duty in connection with the business affairs of the Company or its Subsidiaries or (v) such Participant’s material breach of any agreement between the Participant
and the Company. Any determination by the Company that the Continuous Service of a Participant was terminated with or without Cause for the purposes of outstanding Awards held by such Participant will have no effect upon any determination of the
rights or obligations of the Company or such Participant for any other purpose. 

  
 20. 

 (h) “Change in Control” means the
occurrence, in a single transaction or in a series of related transactions, of any one or more of the following events: 

(i) any Exchange Act Person becomes the Owner, directly or indirectly, of securities of the Company representing more than 50% of the
combined voting power of the Company’s then outstanding securities other than by virtue of a merger, consolidation or similar transaction. Notwithstanding the foregoing, a Change in Control will not be deemed to occur (A) on account of the
acquisition of securities of the Company directly from the Company, (B) on account of the acquisition of securities of the Company by an investor, any affiliate thereof or any other Exchange Act Person that acquires the Company’s
securities in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company through the issuance of equity securities, (C) on account of the acquisition of securities of the Company by any
individual who is, on the IPO Date, either an executive officer or a Director (either, an “IPO Investor”) and/or any entity in which an IPO Investor has a direct or indirect interest (whether in the form of voting rights or
participation in profits or capital contributions) of more than 50% (collectively, the “IPO Entities”) or on account of the IPO Entities continuing to hold shares that come to represent more than 50% of the combined voting
power of the Company’s then outstanding securities as a result of the conversion of any class of the Company’s securities into another class of the Company’s securities having a different number of votes per share pursuant to the
conversion provisions set forth in the Company’s Amended and Restated Certificate of Incorporation; or (D) solely because the level of Ownership held by any Exchange Act Person (the “Subject Person”) exceeds the
designated percentage threshold of the outstanding voting securities as a result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur
(but for the operation of this sentence) as a result of the acquisition of voting securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or
other acquisition had not occurred, increases the percentage of the then outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control will be deemed to occur; 

(ii) there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company and,
immediately after the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly, either (A) outstanding voting securities representing more
than 50% of the combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) more than 50% of the combined outstanding voting power of the parent of the surviving Entity in such merger,
consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such transaction; provided, however, that a merger,
consolidation or similar transaction will not constitute a Change in Control under this prong of the definition if the outstanding voting securities representing more than 50% of the combined voting power of the surviving Entity or its parent are
owned by the IPO Entities; 

  
 21. 

 (iii) there is consummated a sale, lease, exclusive license or other disposition of all or
substantially all of the consolidated assets of the Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries to an Entity, more
than 50% of the combined voting power of the voting securities of which are Owned by stockholders of the Company in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such
sale, lease, license or other disposition; provided, however, that a sale, lease, exclusive license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries will not constitute a Change
in Control under this prong of the definition if the outstanding voting securities representing more than 50% of the combined voting power of the acquiring Entity or its parent are owned by the IPO Entities; or 

(iv) individuals who, on the date the Plan is adopted by the Board, are members of the Board (the “Incumbent
Board”) cease for any reason to constitute at least a majority of the members of the Board; provided, however, that if the appointment or election (or nomination for election) of any new Board member was approved or recommended
by a majority vote of the members of the Incumbent Board then still in office, such new member will, for purposes of this Plan, be considered as a member of the Incumbent Board. 

Notwithstanding the foregoing or any other provision of this Plan, (A) the term Change in Control will not include a sale of
assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company, and (B) the definition of Change in Control (or any analogous term) in an individual written agreement between the Company or any
Affiliate and the Participant will supersede the foregoing definition with respect to Awards subject to such agreement; provided, however, that if no definition of Change in Control or any analogous term is set forth in such an individual
written agreement, the foregoing definition will apply. To the extent required for compliance with Section 409A of the Code, in no event will a Change in Control be deemed to have occurred if such transaction is not also a “change in the
ownership or effective control of” the Company or “a change in the ownership of a substantial portion of the assets of” the Company as determined under Treasury Regulations Section 1.409A-3(i)(5) (without regard to any
alternative definition thereunder). The Board may, in its sole discretion and without a Participant’s consent, amend the definition of “Change in Control” to conform to the definition of “Change in Control” under
Section 409A of the Code, and the regulations thereunder.  
 (i)
“Code” means the Internal Revenue Code of 1986, as amended, including any applicable regulations and guidance thereunder. 

(j) “Committee” means a committee of one or more Directors to whom authority has
been delegated by the Board in accordance with Section 2(c). 
 (k) “Common Stock” means the
common stock of the Company. 
 (l) “Company” means Everbridge, Inc., a Delaware corporation. 

(m) “Consultant” means any person, including an advisor, who is (i) engaged by the Company or an Affiliate
to render consulting or advisory services and is compensated for such services, or (ii) serving as a member of the board of directors of an Affiliate and is compensated for such services. However, service solely as a Director, or payment of a
fee for such service, 

  
 22. 

 
will not cause a Director to be considered a “Consultant” for purposes of the Plan. Notwithstanding the foregoing, a person is treated as a Consultant under this Plan only if a Form S-8
Registration Statement under the Securities Act is available to register either the offer or the sale of the Company’s securities to such person. 

(n) “Continuous Service” means that the Participant’s service with the Company
or an Affiliate, whether as an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an Affiliate as an Employee, Director or Consultant or a change in
the Entity for which the Participant renders such service, provided that there is no interruption or termination of the Participant’s service with the Company or an Affiliate, will not terminate a Participant’s Continuous Service;
provided, however, that if the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, as determined by the Board, in its sole discretion, such Participant’s Continuous Service
will be considered to have terminated on the date such Entity ceases to qualify as an Affiliate. For example, a change in status from an Employee of the Company to a Consultant of an Affiliate or to a Director will not constitute an interruption of
Continuous Service. To the extent permitted by law, the Board or the chief executive officer of the Company, in that party’s sole discretion, may determine whether Continuous Service will be considered interrupted in the case of (i) any
leave of absence approved by the Board or chief executive officer, including sick leave, military leave or any other personal leave, or (ii) transfers between the Company, an Affiliate, or their successors. Notwithstanding the foregoing, a
leave of absence will be treated as Continuous Service for purposes of vesting in an Award only to such extent as may be provided in the Company’s leave of absence policy, in the written terms of any leave of absence agreement or policy
applicable to the Participant, or as otherwise required by law. In addition, to the extent required for exemption from or compliance with Section 409A of the Code, the determination of whether there has been a termination of Continuous Service
will be made, and such term will be construed, in a manner that is consistent with the definition of “separation from service” as defined under Treasury Regulation Section 1.409A-1(h) (without regard to any alternative definition
thereunder). 
 (o) “Corporate Transaction” means the consummation,
in a single transaction or in a series of related transactions, of any one or more of the following events: 
 (i) a
sale or other disposition of all or substantially all, as determined by the Board, in its sole discretion, of the consolidated assets of the Company and its Subsidiaries; 

(ii) a sale or other disposition of more than 50% of the outstanding securities of the Company; 

(iii) a merger, consolidation or similar transaction following which the Company is not the surviving corporation; or 

(iv) a merger, consolidation or similar transaction following which the Company is the surviving corporation but the shares of Common
Stock outstanding immediately preceding the merger, consolidation or similar transaction are converted or exchanged by virtue of the merger, consolidation or similar transaction into other property, whether in the form of securities, cash or
otherwise. 

  
 23.

Section 162(m)(3) of the Code. 
 (q) “Director” means a member of the Board. 

(r) “Disability” means, with respect to a Participant, the inability of such
Participant to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or that has lasted or can be expected to last for a continuous period of not less
than 12 months, as provided in Sections 22(e)(3) and 409A(a)(2)(c)(i) of the Code, and will be determined by the Board on the basis of such medical evidence as the Board deems warranted under the circumstances. 

(s) “Dissolution” means when the Company, after having executed a
certificate of dissolution with the State of Delaware, has completely wound up its affairs. Conversion of the Company into a Limited Liability Company (or any other pass-through entity) will not be considered a “Dissolution” for purposes
of the Plan. 
 (t) “Effective Date” means the effective date of this Plan, which is the IPO
Date. 
 (u) “Employee” means any person employed by the Company or an Affiliate.
However, service solely as a Director, or payment of a fee for such services, will not cause a Director to be considered an “Employee” for purposes of the Plan. 

(v) “Entity” means a corporation, partnership, limited liability company or other entity. 

(w) “Exchange Act” means the Securities Exchange Act of 1934, as amended, and the
rules and regulations promulgated thereunder. 
 (x) “Exchange Act
Person” means any natural person, Entity or “group” (within the meaning of Section 13(d) or 14(d) of the Exchange Act), except that “Exchange Act Person” will not include (i) the Company or any Subsidiary
of the Company, (ii) any employee benefit plan of the Company or any Subsidiary of the Company or any trustee or other fiduciary holding securities under an employee benefit plan of the Company or any Subsidiary of the Company, (iii) an
underwriter temporarily holding securities pursuant to a registered public offering of such securities, (iv) an Entity Owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their Ownership of
stock of the Company; or (v) any natural person, Entity or “group” (within the meaning of Section 13(d) or 14(d) of the Exchange Act) that, as of the Effective Date, is the Owner, directly or indirectly, of securities of the
Company representing more than50% of the combined voting power of the Company’s then outstanding securities. 
 (y)
“Fair Market Value” means, as of any date, the value of the Common Stock determined as follows: 
 (i) If
the Common Stock is listed on any established stock exchange or traded on any established market, the Fair Market Value of a share of Common Stock will be, unless otherwise determined by the Board, the closing sales price for such stock as quoted on
such exchange or market (or the exchange or market with the greatest volume of trading in the Common Stock) on the date of determination, as reported in a source the Board deems reliable. 

  
 24. 

 (ii) Unless otherwise provided by the Board, if there is no closing sales price for the
Common Stock on the date of determination, then the Fair Market Value will be the closing selling price on the last preceding date for which such quotation exists. 

(iii) In the absence of such markets for the Common Stock, the Fair Market Value will be determined by the Board in good faith and in a
manner that complies with Sections 409A and 422 of the Code. 
 (z) “Incentive Stock
Option” means an option granted pursuant to Section 5 of the Plan that is intended to be, and that qualifies as, an “incentive stock option” within the meaning of Section 422 of the Code. 

(aa) “IPO Date” means the date of the underwriting agreement between the Company
and the underwriter(s) managing the initial public offering of the Common Stock, pursuant to which the Common Stock is priced for the initial public offering.

employee or officer of the Company or an Affiliate, does not receive compensation, either directly or indirectly, from the Company or an Affiliate for services rendered as a consultant or in any capacity other than as a Director (except for an
amount as to which disclosure would not be required under Item 404(a) of Regulation S-K promulgated pursuant to the Securities Act (“Regulation S-K”)), does not possess an interest in any other transaction for which
disclosure would be required under Item 404(a) of Regulation S-K, and is not engaged in a business relationship for which disclosure would be required pursuant to Item 404(b) of Regulation S-K; or (ii) is otherwise considered a
“non-employee director” for purposes of Rule 16b-3. 
 (cc)
“Nonstatutory Stock Option” means any option granted pursuant to Section 5 of the Plan that does not qualify as an Incentive Stock Option. 

(dd) “Officer” means a person who is an officer of the Company within the meaning of Section 16 of the
Exchange Act. 
 (ee) “Option” means an Incentive Stock Option or a Nonstatutory
Stock Option to purchase shares of Common Stock granted pursuant to the Plan. 
 (ff)
“Option Agreement” means a written agreement between the Company and an Optionholder evidencing the terms and conditions of an Option grant. Each Option Agreement will be subject to the terms and conditions
of the Plan. 
 (gg) “Optionholder” means a person to whom an
Option is granted pursuant to the Plan or, if applicable, such other person who holds an outstanding Option. 

(hh) “Other Stock Award” means an award based in whole or in part by reference to
the Common Stock which is granted pursuant to the terms and conditions of Section 6(d). 

  
 25. 

 (ii) “Other Stock Award Agreement”
means a written agreement between the Company and a holder of an Other Stock Award evidencing the terms and conditions of an Other Stock Award grant. Each Other Stock Award Agreement will be subject to the terms and conditions of the Plan.

 (jj) “Outside Director” means a Director who either (i) is not a

 ATTACHMENT I 

OPTION AGREEMENT 

 EVERBRIDGE, INC. 

2016 EQUITY INCENTIVE PLAN 

OPTION AGREEMENT 

(INCENTIVE STOCK OPTION OR NONSTATUTORY STOCK
OPTION) 
 Pursuant to your Stock Option Grant Notice (“Grant Notice”) and this Option Agreement,
Everbridge, Inc. (the “Company”) has granted you an option under its 2016 Equity Incentive Plan (the “Plan”) to purchase the number of shares of the Company’s Common Stock indicated in your Grant
Notice at the exercise price indicated in your Grant Notice. The option is granted to you effective as of the date of grant set forth in the Grant Notice (the “Date of Grant”). If there is any conflict between the terms in
this Option Agreement and the Plan, the terms of the Plan will control. Capitalized terms not explicitly defined in this Option Agreement or in the Grant Notice but defined in the Plan will have the same definitions as in the Plan. 

The details of your option, in addition to those set forth in the Grant Notice and the Plan, are as follows: 

1. VESTING. Subject to the provisions contained herein, your option will vest as provided in your Grant Notice. Vesting
will cease upon the termination of your Continuous Service. 
 2. NUMBER OF SHARES
AND EXERCISE PRICE. The number of shares of Common Stock subject to your option and your exercise price per share in your Grant Notice will be adjusted for Capitalization Adjustments. 

3. EXERCISE RESTRICTION FOR NON-EXEMPT
EMPLOYEES. If you are an Employee eligible for overtime compensation under the Fair Labor Standards Act of 1938, as amended (that is, a “Non-Exempt Employee”), and except as otherwise provided in the Plan,
you may not exercise your option until you have completed at least six (6) months of Continuous Service measured from the Date of Grant, even if you have already been an employee for more than six (6) months. Consistent with the provisions
of the Worker Economic Opportunity Act, you may exercise your option as to any vested portion prior to such six (6) month anniversary in the case of (i) your death or disability, (ii) a Corporate Transaction in which your option is
not assumed, continued or substituted, (iii) a Change in Control or (iv) your termination of Continuous Service on your “retirement” (as defined in the Company’s benefit plans). 

4. METHOD OF PAYMENT. You must pay the full amount of the exercise price for the shares
you wish to exercise. You may pay the exercise price in cash or by check, bank draft or money order payable to the Company or in any other manner permitted by your Grant Notice, which may include one or more of the following: 

(a) Provided that at the time of exercise the Common Stock is publicly traded, pursuant to a program developed under Regulation T as
promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from
the sales proceeds. This manner of payment is also known as a “broker-assisted exercise”, “same day sale”, or “sell to cover”. 

  
 1. 

 (b) Provided that at the time of exercise the Common Stock is publicly traded, by delivery
to the Company (either by actual delivery or attestation) of already-owned shares of Common Stock that are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at Fair Market Value on the date of
exercise. “Delivery” for these purposes, in the sole discretion of the Company at the time you exercise your option, will include delivery to the Company of your attestation of ownership of such shares of Common Stock in a form approved by
the Company. You may not exercise your option by delivery to the Company of Common Stock if doing so would violate the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. 

(c) If this option is a Nonstatutory Stock Option, subject to the consent of the Company at the time of exercise, by a “net
exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issued upon exercise of your option by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise
price. You must pay any remaining balance of the aggregate exercise price not satisfied by the “net exercise” in cash or other permitted form of payment. Shares of Common Stock will no longer be outstanding under your option and will not
be exercisable thereafter if those shares (i) are used to pay the exercise price pursuant to the “net exercise,” (ii) are delivered to you as a result of such exercise, and (iii) are withheld to satisfy your tax withholding
obligations. 
 5. WHOLE SHARES. You may exercise your option only for whole shares of Common Stock.

 6. SECURITIES LAW COMPLIANCE. In no event may you exercise your option unless the
shares of Common Stock issuable upon exercise are then registered under the Securities Act or, if not registered, the Company has determined that your exercise and the issuance of the shares would be exempt from the registration requirements of the
Securities Act. The exercise of your option also must comply with all other applicable laws and regulations governing your option, and you may not exercise your option if the Company determines that such exercise would not be in material compliance
with such laws and regulations (including any restrictions on exercise required for compliance with Treas. Reg. 1.401(k)-1(d)(3), if applicable). 

7. TERM. You may not exercise your option before the Date of Grant or after the expiration of the option’s term.
The term of your option expires, subject to the provisions of Sections 5(h) and 9(c) of the Plan, upon the earliest of the following: 

(a) immediately upon the termination of your Continuous Service for Cause; 

(b) three (3) months after the termination of your Continuous Service for any reason other than Cause, your Disability or your
death (except as otherwise provided in Section 7(d) below); provided, however, that if during any part of such three (3) month period your option is not exercisable solely because of the condition set forth in the section above
relating to “Securities Law Compliance,” your option will not expire until the earlier of the Expiration Date or until it has been exercisable for an aggregate period of three (3) months after the termination of your Continuous
Service; provided further, that if (i) you are a Non-Exempt Employee, (ii) your Continuous Service terminates within six (6) months after the Date of Grant, and (iii) you have vested in a portion of your option at the time
of your termination of Continuous Service, your option will not expire until the earlier of (x) the later of (A) the date that is seven (7) months after the Date of Grant, and (B) the date that is three (3) months after the
termination of your Continuous Service, and (y) the Expiration Date; 
 (c) twelve (12) months after the termination of
your Continuous Service due to your Disability (except as otherwise provided in Section 7(d)) below; 

  
 2. 

 (d) eighteen (18) months after your death if you die either during your Continuous
Service or within three (3) months after your Continuous Service terminates for any reason other than Cause; 
 (e) the
Expiration Date indicated in your Grant Notice; or 
 (f) the day before the tenth (10th) anniversary of the Date of Grant. 

If your option is an Incentive Stock Option, note that to obtain the federal income tax advantages associated with an Incentive Stock Option,
the Code requires that at all times beginning on the Date of Grant and ending on the day three (3) months before the date of your option’s exercise, you must be an employee of the Company or an Affiliate, except in the event of your death
or Disability. The Company has provided for extended exercisability of your option under certain circumstances for your benefit but cannot guarantee that your option will necessarily be treated as an Incentive Stock Option if you continue to provide
services to the Company or an Affiliate as a Consultant or Director after your employment terminates or if you otherwise exercise your option more than three (3) months after the date your employment with the Company or an Affiliate terminates.

 8. EXERCISE. 

(a) You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so permits) during
its term by (i) delivering a Notice of Exercise (in a form designated by the Company) or completing such other documents and/or procedures designated by the Company for exercise and (ii) paying the exercise price and any applicable
withholding taxes to the Company’s Secretary, stock plan administrator, or such other person as the Company may designate, together with such additional documents as the Company may then require. 

(b) By exercising your option you agree that, as a condition to any exercise of your option, the Company may require you to enter into
an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (i) the exercise of your option, (ii) the lapse of any substantial risk of forfeiture to which the shares
of Common Stock are subject at the time of exercise, or (iii) the disposition of shares of Common Stock acquired upon such exercise. 

(c) If your option is an Incentive Stock Option, by exercising your option you agree that you will notify the Company in writing within
fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the Date of Grant or within one (1) year after such shares of
Common Stock are transferred upon exercise of your option. 
 (d) [By exercising your option you agree that you will not sell,
dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale with respect to any shares of Common Stock or other securities of the
Company held by you, for a period of one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act or such longer period as the underwriters or the Company will request to
facilitate compliance with FINRA Rule 2241 or any successor or similar rules or regulation (the “Lock-Up Period”); provided, however, that nothing contained in this Section will prevent the exercise of a
repurchase option, if any, in favor of the Company during the Lock-Up Period. You further agree to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriters that are consistent with the foregoing or
that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may 

  
 3. 

 
impose stop-transfer instructions with respect to your shares of Common Stock until the end of such period. You also agree that any transferee of any shares of Common Stock (or other securities)
of the Company held by you will be bound by this Section 8(d). The underwriters of the Company’s stock are intended third party beneficiaries of this Section 8(d) and will have the right, power and authority to enforce the provisions
hereof as though they were a party hereto.]2 
 9.
TRANSFERABILITY. Except as otherwise provided in this Section 9, your option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. 

(a) Certain Trusts. Upon receiving written permission from the Board or its duly authorized designee, you may transfer your option to a
trust if you are considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable state law) while the option is held in the trust. You and the trustee must enter into transfer and other agreements required by
the Company. 
 (b) Domestic Relations Orders. Upon receiving written permission from the Board or its duly authorized designee, and
provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your option pursuant to the terms of a domestic relations order, official marital settlement agreement or other
divorce or separation instrument as permitted by Treasury Regulation 1.421-1(b)(2) that contains the information required by the Company to effectuate the transfer. You are encouraged to discuss the proposed terms of any division of this option with
the Company prior to finalizing the domestic relations order or marital settlement agreement to help ensure the required information is contained within the domestic relations order or marital settlement agreement. If this option is an Incentive
Stock Option, this option may be deemed to be a Nonstatutory Stock Option as a result of such transfer. 
 (c) Beneficiary
Designation. Upon receiving written permission from the Board or its duly authorized designee, you may, by delivering written notice to the Company, in a form approved by the Company and any broker designated by the Company to handle
option exercises, designate a third party who, on your death, will thereafter be entitled to exercise this option and receive the Common Stock or other consideration resulting from such exercise. In the absence of such a designation, your executor
or administrator of your estate will be entitled to exercise this option and receive, on behalf of your estate, the Common Stock or other consideration resulting from such exercise. 

10. OPTION NOT A SERVICE CONTRACT. Your option is not an
employment or service contract, and nothing in your option will be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of the Company or an Affiliate to continue your
employment. In addition, nothing in your option will obligate the Company or an Affiliate, their respective shareholders, boards of directors, officers or employees to continue any relationship that you might have as a Director or Consultant for the
Company or an Affiliate. 
 11. WITHHOLDING OBLIGATIONS. 

(a) At the time you exercise your option, in whole or in part, and at any time thereafter as requested by the Company, you hereby
authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a 
  

 

	2 	 NTD: For inclusion in option grants, if any, made during lock-up period.

  
 4. 

 
“same day sale” pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the
federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise of your option. 

(b) If this option is a Nonstatutory Stock Option, then upon your request and subject to approval by the Company, and compliance with
any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of Common Stock having a Fair Market Value,
determined by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid classification of your option as a liability for financial accounting
purposes). Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully vested shares of Common Stock determined as of the date of exercise of your option that are otherwise issuable to you upon such
exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. 

(c) You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied.
Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company will have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from any
escrow provided for herein, if applicable, unless such obligations are satisfied. 
 12. TAX
CONSEQUENCES. You hereby agree that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You will not make any claim
against the Company, or any of its Officers, Directors, Employees or Affiliates related to tax liabilities arising from your option or your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of the
Code only if the exercise price per share specified in the Grant Notice is at least equal to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associated
with the option. 
 13. NOTICES. Any notices provided for in your option or the Plan will be given in writing
(including electronically) and will be deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the
last address you provided to the Company. The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this option by electronic means or to request your consent to participate in the Plan by
electronic means. By accepting this option, you consent to receive such documents by electronic delivery and to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party
designated by the Company. 
 14. GOVERNING PLAN DOCUMENT. Your option is subject to all
the provisions of the Plan, the provisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations, which may from time to time be promulgated and adopted pursuant to the Plan.
If there is any conflict between the provisions of your option and those of the Plan, the provisions of the Plan will control. In addition, your option (and any compensation paid or shares issued under your option) is subject to recoupment in
accordance with The Dodd–Frank Wall Street Reform and Consumer Protection Act and any implementing regulations thereunder, any clawback policy adopted by the Company and any compensation recovery policy otherwise required by applicable law. No
recovery of compensation under such a clawback policy will be an event giving rise to a right to voluntarily terminate employment upon a resignation for “good reason,” or for a “constructive termination” or any similar term under
any plan of or agreement with the Company. 

  
 5. 

 15. OTHER DOCUMENTS. You hereby acknowledge
receipt of and the right to receive a document providing the information required by Rule 428(b)(1) promulgated under the Securities Act, which includes the Plan prospectus. In addition, you acknowledge receipt of the Company’s policy
permitting certain individuals to sell shares only during certain “window” periods and the Company’s insider trading policy, in effect from time to time. 

16. EFFECT ON OTHER EMPLOYEE BENEFIT
PLANS. The value of this option will not be included as compensation, earnings, salaries, or other similar terms used when calculating your benefits under any employee benefit plan sponsored by the Company or any
Affiliate, except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any Affiliate’s employee benefit plans. 

17. VOTING RIGHTS. You will not have voting or any other rights as a shareholder of the
Company with respect to the shares to be issued pursuant to this option until such shares are issued to you. Upon such issuance, you will obtain full voting and other rights as a shareholder of the Company. Nothing contained in this option, and no
action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person. 

18. SEVERABILITY. If all or any part of this Option Agreement or the Plan is declared by any court or
governmental authority to be unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Option Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Option Agreement (or part of such a
Section) so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 

19. MISCELLANEOUS. 

(a) The rights and obligations of the Company under your option will be transferable to any one or more persons or entities, and all
covenants and agreements hereunder will inure to the benefit of, and be enforceable by the Company’s successors and assigns.
