	1.	GENERAL. 

 (a)     Establishment. Cempra, Inc., a Delaware
corporation, hereby establishes the Cempra, Inc. 2011 Equity Incentive Plan (as may be amended from time to time, the “Plan”) effective as of February 2, 2012, the date of its approval by the stockholders
of the Company (the “Effective Date”). 
 (b)     Successor to Prior
Plan. This Plan is intended as the successor to the Company’s Sixth Amended and Restated 2006 Stock Plan (the “Prior Plan”). Following the Effective Date, no additional stock awards shall be granted under the
Prior Plan. Any shares remaining available for issuance pursuant to the exercise of options or settlement of stock awards under the Prior Plan shall become available for issuance pursuant to Stock Awards granted hereunder, as provided in
Section 3(a) hereof. Any shares subject to outstanding stock awards granted under the Prior Plan that expire or terminate for any reason prior to exercise or settlement shall become available for issuance pursuant to Stock Awards granted
hereunder, as provided in Section 3(b) hereof. All outstanding stock awards granted under the Prior Plan shall remain subject to the terms of the Prior Plan with respect to which they were originally granted. 

(c)     Eligible Award Recipients. The persons eligible to receive Stock Awards are Employees, Directors and
Consultants. 
 (d)     Available Awards. The Plan provides for the grant of the following Stock Awards:
(i) Incentive Stock Options, (ii) Nonstatutory Stock Options, (iii) Restricted Stock Awards, (iv) Restricted Stock Unit Awards, (v) Stock Appreciation Rights, (vi) Performance Stock Awards and (vii) Other Stock
Awards. 
 (e)     Purpose. The purpose of the Plan is to advance the interests of the Company and its
stockholders by providing an incentive to attract, retain and reward persons eligible to receive Stock Awards as set forth in Section 1(c), and by motivating such persons to contribute to the growth and profitability of the Company. 

 

	2.	ADMINISTRATION. 

 (a)     Administration by Board. The Board
shall administer the Plan unless and until the Board delegates administration of the Plan to a Committee or Committees, as provided in Section 2(c). 

(b)     Powers of Board. The Board shall have the power, subject to, and within the limitations of, the
express provisions of 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 each Stock Award shall be granted; (C) what type or combination of types of Stock Awards shall be granted; (D) the provisions of each Stock Award granted (which need not
be identical), including the time or times when a person shall be permitted to receive cash or Common Stock pursuant to a Stock Award; and (E) the number of shares of Common Stock with respect to which a Stock Award shall be granted to each
such person. 







 (ii)     To determine the provisions of each Stock Award granted
(which need not be identical), including without limitation, (A) the exercise or purchase price of shares of Common Stock purchased pursuant to any Stock Award, (B) the method of payment for shares of Common Stock purchased pursuant to any
Stock Award, (C) the method for satisfaction of any tax withholding obligation arising in connection with Stock Award, including by the withholding or delivery of shares of Common Stock, (D) the timing, terms and conditions of the
exercisability or vesting of any Stock Award or any shares acquired pursuant thereto, (E) the Performance Criteria necessary to satisfy Performance Goals applicable to any Stock Award and the extent to which such Performance Goals have been
attained, (F) the time of the expiration of any Stock Award, (G) the effect of the Participant’s termination of Continuous Service on any of the foregoing, and (H) all other terms, conditions and restrictions applicable to any
Stock Award or shares acquired pursuant thereto not inconsistent with the terms of the Plan. 
 (iii)     To
construe and interpret the Plan and Stock Awards granted under it, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this 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 or Stock Award fully effective. 

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

(v)     To accelerate, continue, extend or defer 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. 

(vi)     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. 

(vii)     To amend the Plan in any respect the Board deems necessary or advisable, including, without limitation,
relating to Incentive Stock Options and certain nonqualified deferred compensation under Section 409A of the Code and/or to bring the Plan or Stock Awards granted under the Plan into compliance therewith, subject to the limitations, if any, of
applicable law. However, except as provided in Section 9(a) relating to Capitalization Adjustments, stockholder approval shall be required for any amendment of the Plan that either (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 Stock Awards under the Plan, (C) materially increases the benefits accruing to Participants under the Plan or materially
reduces the price at which shares of Common Stock may be issued or purchased under the Plan, (D) materially extends the term of the Plan, or (E) expands the types of Stock Awards available for issuance under the Plan, but in each of
(A) through (E) only to the extent required by applicable law or listing requirements. Except as provided above, rights under any Stock Award granted before amendment of the Plan shall not be impaired by any amendment of the Plan unless
(1) the Company requests the consent of the affected Participant, and (2) such Participant consents in writing. 

(viii)     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 and the regulations thereunder 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. 

  
 2 








 (ix)     To approve forms of Stock Award Agreements for use under the
Plan and 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 a Participant’s 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, the Board may amend the terms of any one or more Stock Awards without the affected Participant’s consent 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 the related guidance thereunder. 

(x)     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 Stock Awards. 

(xi)     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. 
 (xii)    
To effect, at any time and from time to time, with the consent of any adversely affected Participant, (A) the reduction of the exercise price (or strike price) of any outstanding Option or Stock Appreciation Right under the Plan;
(B) the cancellation of any outstanding Option or Stock Appreciation Right under the Plan and the grant in substitution therefor of (1) a new Option or Stock Appreciation Right under the Plan or another equity plan of the Company covering
the same or a different number of shares of Common Stock, (2) a Restricted Stock Award, (3) a Restricted Stock Unit Award, (4) an Other Stock Award, (5) cash and/or (6) other valuable consideration (as determined by the
Board, in its sole discretion); or (C) any other action that is treated as a repricing under generally accepted accounting principles. 

(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 is delegated to a Committee, the Committee shall 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 the Plan to the Board shall thereafter be to the Committee or subcommittee), 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 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. In the sole discretion of the Board, 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. In addition, the Board or the Committee, in its sole discretion, may (A) delegate to a Committee who need not be Outside Directors the authority to grant Stock Awards to eligible persons who are either (I) not then Covered
Employees and are not expected to be Covered Employees at the time of recognition of income resulting from such Stock Award, or (II) not persons with respect to whom the Company wishes to comply with Section 162(m) of the Code, or
(B) delegate to a Committee who need not be Non-Employee Directors the authority to grant Stock Awards to eligible persons who are not then subject to Section 16 of the Exchange Act. 

  
 3 








 (d)     Delegation to Officers. The Board may delegate to one or
more Officers the authority to do one or both of the following (i) designate Employees of the Company or any of its Subsidiaries to be recipients of Options (and, to the extent permitted by Delaware law, other Stock Awards) and the terms
thereof, 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 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 2(d), the Board may not
delegate to an Officer authority to determine the Fair Market Value of the Common Stock pursuant to Section 12(u)(ii) below. 

(e)     Repricing. The Board shall not approve a program providing for either (a) the cancellation of
outstanding Stock Awards and the grant in substitution therefor of new Stock Awards having a lower exercise or purchase price or (b) the amendment of outstanding Stock Awards to reduce the exercise price thereof, unless the stockholders of the
Company have approved such an action within twelve (12) months prior to such an event. This paragraph shall not be construed to apply to “issuing or assuming a stock option in a transaction to which section 424(a) applies,”
within the meaning of Section 424 of the Code.
 (f)     Effect of Board’s Decision. All
determinations, interpretations and constructions made by the Board in good faith shall not be subject to review by any person and shall be final, binding and conclusive on all persons. 

(g)     Indemnification. In addition to such other rights of indemnification as they may have as members of the
Board or the Committee or as officers or employees of the Company, members of the Board or the Committee and any officers or employees of the Company to whom authority to act for the Board, the Committee or the Company is delegated shall be
indemnified by the Company against all reasonable expenses, including attorneys’ fees, actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in connection with any appeal therein, to which they
or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any right granted hereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by
independent legal counsel selected by the Company) or paid by them in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such action, suit or proceeding that such
person is liable for gross negligence, bad faith or intentional misconduct in duties; provided, however, that within sixty (60) days after the institution of such action, suit or proceeding, such person shall offer to the
Company, in writing, the opportunity at its own expense to handle and defend the same. 
  

	3.	SHARES SUBJECT TO THE PLAN.

 (a)     Share
Reserve. Subject to the provisions of Section 9(a) relating to Capitalization Adjustments, the aggregate number of shares of Common Stock that may be issued pursuant to Stock Awards under the Plan is equal to Four Million Eight Hundred
Forty-Two Thousand One Hundred Five (4,842,105) shares (the “Share Reserve”). In addition, the number of shares of Common Stock available for issuance under the Plan shall automatically increase on January 1st of
each year for a period of nine (9) years commencing on January 1, 2013 and ending on (and including) January 1, 2021, in an amount equal to four percent (4%) 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 the first 

  
 4 








 
day of any calendar year, to provide that there shall be no increase in the share reserve for such calendar year or that the increase in the share reserve for such calendar year shall be a lesser
number of shares of Common Stock than would otherwise occur pursuant to the preceding sentence. For clarity, the limitation in this Section 3(a) is a limitation in 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, as applicable, NASDAQ Marketplace Rule
4350(i)(1)(A)(iii), NYSE Listed Company Manual Section 303A.08, AMEX Company Guide Section 711 or other applicable stock exchange rules, and such issuance shall not reduce the number of shares available for issuance under the Plan. If an
outstanding Stock Award for any reason expires or is terminated or canceled without having been exercised or settled in full, or if shares of Common Stock acquired pursuant to a Stock Award subject to forfeiture or repurchase are forfeited or
repurchased by the Company at the Participant’s purchase price to effect a forfeiture of unvested shares upon termination of Continuous Service, the shares of Common Stock allocable to the terminated portion of such Stock Award or such
forfeited or repurchased shares of Common Stock shall be added back to the Share Reserve and again be available for issuance under the Plan. Shares of Common Stock shall not be deemed to have been issued pursuant to the Plan with respect to any
portion of a Stock Award (other than a Stock Appreciation Right that may be settled in shares of Common Stock and/or cash) that is settled in cash. Shares withheld in satisfaction of tax withholding obligations pursuant to Section 8(g) shall
not again become available for issuance under the Plan. Upon exercise of a Stock Appreciation Right, whether in cash or shares of Common Stock, the number of shares available for issuance under the Plan shall be reduced by the gross number of shares
for which the Stock Appreciation Right is exercised. If the exercise price of an Option is paid by “net exercise” (as described in Section 5(c)(iv)) or tender to the Company, or attestation to the ownership, of shares of Common Stock
owned by the Participant, the number of shares available for issuance under the Plan shall be reduced by the gross number of shares for which the Option is exercised. 

(b)     Additions to the Share Reserve. The Share Reserve also shall be increased from time to time by a
number of shares equal to the number of shares of Common Stock that (i) are issuable pursuant to awards outstanding under the Prior Plan as of the Effective Date and (ii) but for the termination of the Prior Plan as of the Effective Date,
would otherwise have reverted to the share reserve of the Prior Plan pursuant to the provisions thereof. 
 (c)    
Incentive Stock Option Limit. Notwithstanding anything to the contrary in this Section 3(c), subject to the provisions of 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 shall be Four Million Eight Hundred Forty-Two Thousand One Hundred Five (4,842,105) shares of Common Stock. 

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

	4.	ELIGIBILITY.

 (a)     Eligibility for Specific Stock
Awards. Incentive Stock Options may be granted only to Employees. Stock Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants. 

  
 5 








 (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 on the date of grant and the Option is not exercisable after the
expiration of five (5) years from the date of grant. 
 (c)     Section 162(m) Limitation. Subject
to the provisions of 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, no Employee shall be eligible to be granted during any
calendar year Stock Awards whose value is determined by reference to an increase over an exercise or strike price of at least one hundred percent (100%) of the Fair Market Value of the Common Stock on the date the Stock Award is granted
covering more than Seven Hundred Sixty-Three Thousand One Hundred Fifty-Eight (763,158) shares of Common Stock. 

(d)     Consultants. A Consultant shall be eligible for the grant of a Stock Award only if, at the time of
grant, a Form S-8 Registration Statement under the Securities Act (“Form S-8”) is available to register either the offer or the sale of the Company’s securities to such Consultant. 

 

	5.	OPTION PROVISIONS.

 Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. All Options shall 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 shall 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, then the Option shall be a Nonstatutory Stock Option. The provisions of separate Options need
not be identical; provided, however, that each Option Agreement shall conform to (through incorporation of provisions hereof by reference in the Option 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
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. 

(b)     Exercise Price. Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders, the
exercise price of each Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an 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 Option is granted pursuant to an assumption or substitution for another option in a manner consistent with the
provisions of Section 409A and Section 424(a) of the Code (whether or not such options are Incentive Stock Options). 

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

  
 6 








 (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; 
 (iv)     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 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, that 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 reduced 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 in its sole discretion and
permissible under applicable law. 
 (d)     Transferability of Options. The Board may, in its sole
discretion, impose such limitations on the transferability of Options as the Board shall determine. In the absence of such a determination by the Board to the contrary, 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 Optionholder only by the Optionholder; provided, however, that the Board may, in its sole discretion, permit transfer of the Option in a manner that is not prohibited by
applicable tax and securities laws upon the Optionholder’s request. 
 (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 may be deemed to be a Nonstatutory Stock Option as a result of
such transfer. 
 (iii)     Beneficiary Designation. Notwithstanding the foregoing, the Optionholder may, by
delivering written notice to the Company, in a form provided by or otherwise satisfactory to the Company and any broker designated by the Company to effect Option exercises, designate a third party who, in the event of the death of the Optionholder,
shall thereafter be entitled to exercise the Option. In the absence of such a designation, the executor or administrator of the Optionholder’s estate shall be entitled to exercise the Option. 

(e)     Vesting of Options Generally. The total number of shares of Common Stock subject to an Option may vest
and therefore become exercisable in periodic installments that may or may not be equal. The Option 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 may vary. The provisions of this Section 5(e) are subject to any Option provisions governing the minimum number of shares of
Common Stock as to which an Option may be exercised. 

  
 7 








 (f)     Termination of Continuous Service. In the event that an
Optionholder’s Continuous Service terminates (other than for Cause or upon the Optionholder’s death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option
as of the date of termination of Continuous Service) but only within such period of time ending on the earlier of (i) the date three (3) months following the termination of the Optionholder’s Continuous Service (or such longer or
shorter period specified in the Option Agreement), or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination of Continuous Service, the Optionholder does not exercise his or her Option within
the time specified herein or in the Option Agreement (as applicable), the Option shall terminate. 
 (g)    
Extension of Termination Date. An Optionholder’s Option Agreement may provide that if the exercise of the Option following the termination of the Optionholder’s Continuous Service (other than for Cause or upon the
Optionholder’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 Optionholder’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. In addition, unless otherwise provided in an Optionholder’s Option Agreement, if the sale of the Common Stock received upon exercise of an Option following the
termination of the Optionholder’s Continuous Service (other than for Cause) would violate the Company’s Insider Trading Policy, then the Option shall terminate on the earlier of (i) the expiration of a period equal to the
post-termination exercise period described in Section 5(f) above or Sections 5(h) or 5(i) below after the termination of the Optionholder’s Continuous Service during which the exercise of the Option would not be in violation of the
Company’s Insider Trading Policy; or (ii) the expiration of the term of the Option as set forth in the Option Agreement. 

(h)     Disability of Optionholder. In the event that an Optionholder’s Continuous Service terminates as
a result of the Optionholder’s Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination of Continuous Service), but only within such
period of time ending on the earlier of (i) the date twelve (12) months following such termination of Continuous Service (or such longer or shorter period specified in the Option Agreement), or (ii) the expiration of the term of the
Option as set forth in the Option Agreement. If, after termination of Continuous Service, the Optionholder does not exercise his or her Option within the time specified herein or in the Option Agreement (as applicable), the Option shall terminate.

 (i)     Death of Optionholder. In the event that (i) an Optionholder’s Continuous Service
terminates as a result of the Optionholder’s death, or (ii) the Optionholder dies within the period (if any) specified in the Option Agreement after the termination of the Optionholder’s Continuous Service for a reason other than
death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise such Option as of the date of death) by the Optionholder’s estate, by a person who acquired the right to exercise the Option by bequest or
inheritance or by a person designated to exercise the option upon the Optionholder’s death, but only within the period ending on the earlier of (A) the date twelve (12) months following the date of death (or such longer or shorter
period specified in the Option Agreement), or (B) the expiration of the term of such Option as set forth in the Option Agreement. If, after the Optionholder’s death, the Option is not exercised within the time specified herein or in the
Option Agreement (as applicable), the Option shall terminate. 
 (j)     Termination for Cause. Except as
explicitly provided otherwise in an Optionholder’s Option Agreement, in the event that an Optionholder’s Continuous Service is terminated for Cause, the Option shall terminate upon the termination date of such Optionholder’s
Continuous Service, and the Optionholder shall be prohibited from exercising his or her Option from and after the time of such termination of Continuous Service. 

  
 8 








 (k)     Non-Exempt Employees. No Option granted to an Employee
who is a non-exempt employee for purposes of the Fair Labor Standards Act 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. 
  

	6.	PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS.


(a)     Restricted Stock Awards. Each Restricted Stock Award Agreement shall be in such form and shall
contain such terms and conditions as the Board shall deem appropriate. To the extent consistent with the Company’s Bylaws, at the Board’s election, shares of Common Stock may be (x) held in book entry form subject to the
Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (y) evidenced by a certificate, which certificate shall 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, provided, however, that each Restricted Stock Award Agreement shall 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 or future services actually or to be rendered to the Company or an Affiliate; or (C) any other form of legal consideration that may be acceptable to the Board in its sole discretion and
permissible under applicable law. 
 (ii)     Vesting. Shares of Common Stock awarded under a 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. In the event a Participant’s Continuous
Service terminates, the Company may receive via a forfeiture condition or a repurchase right, any or all of the shares of Common Stock held by the Participant which 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 shall be transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board shall 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. 

(b)     Restricted Stock Unit Awards. Each Restricted Stock Unit Award Agreement shall be in such form and
shall contain such terms and conditions as the Board shall deem 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, provided, however, that each Restricted Stock Unit Award Agreement shall conform to (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the
following provisions: 

  
 9 








 (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 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 the 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. 
 (vii)     Compliance with Section 409A of the
Code. Notwithstanding anything to the contrary set forth herein, any Restricted Stock Unit Award granted under the Plan that is not exempt from the requirements of Section 409A of the Code shall incorporate terms and conditions
necessary to avoid the consequences of Section 409A(a)(1) of the Code. Such restrictions, if any, shall be determined by the Board and contained in the Restricted Stock Unit Award Agreement evidencing such Restricted Stock Unit Award. 

(c)     Stock Appreciation Rights. Each Stock Appreciation Right Agreement shall be in such form and shall
contain such terms and conditions as the Board shall deem appropriate. Stock Appreciation Rights may be granted as stand-alone Stock Awards or in tandem with other Stock Awards. The terms and conditions of Stock Appreciation Right Agreements may
change from time to time, and the terms and conditions of separate Stock Appreciation Right Agreements need not be identical; provided, however, that each Stock Appreciation Right Agreement shall conform to (through incorporation of the
provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions: 

(i)     Term. No Stock Appreciation Right shall be exercisable after the expiration of ten (10) years
from the date of its grant or such shorter period specified in the Stock Appreciation Right Agreement. 

  
 10 








 (ii)     Strike Price. Each Stock Appreciation Right will be
denominated in shares of Common Stock equivalents. The strike price of each Stock Appreciation Right shall not be less than one hundred percent (100%) of the Fair Market Value of the Common Stock equivalents subject to the Stock Appreciation
Right on the date of grant. 
 (iii)     Calculation of Appreciation. The appreciation distribution payable
on the exercise of a Stock Appreciation Right 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 Stock Appreciation Right) of a number of shares of Common Stock
equal to the number of shares of Common Stock equivalents in which the Participant is vested under such Stock Appreciation Right, and with respect to which the Participant is exercising the Stock Appreciation Right on such date, over (B) the
strike price. 
 (iv)     Vesting. At the time of the grant of a Stock Appreciation Right, the Board may
impose such restrictions or conditions to the vesting of such Stock Appreciation Right as it, in its sole discretion, deems appropriate. 

(v)     Exercise. To exercise any outstanding Stock Appreciation Right, the Participant must provide written
notice of exercise to the Company in compliance with the provisions of the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. 

(vi)     Payment. The appreciation distribution in respect of a Stock Appreciation Right 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 set forth in the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. 

(vii)     Termination of Continuous Service. In the event that a Participant’s Continuous Service
terminates (other than for Cause), the Participant may exercise his or her Stock Appreciation Right (to the extent that the Participant was entitled to exercise such Stock Appreciation Right as of the date of termination of Continuous Service) but
only within such period of time ending on the earlier of (A) the date three (3) months following the termination of the Participant’s Continuous Service (or such longer or shorter period specified in the Stock Appreciation Right
Agreement), or (B) the expiration of the term of the Stock Appreciation Right as set forth in the Stock Appreciation Right Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Stock Appreciation
Right within the time specified herein or in the Stock Appreciation Right Agreement (as applicable), the Stock Appreciation Right shall terminate. 

(viii)     Termination for Cause. Except as explicitly provided otherwise in an Participant’s Stock
Appreciation Right Agreement, in the event that a Participant’s Continuous Service is terminated for Cause, the Stock Appreciation Right shall terminate upon the termination date of such Participant’s Continuous Service, and the
Participant shall be prohibited from exercising his or her Stock Appreciation Right from and after the time of such termination of Continuous Service. 

(ix)     Compliance with Section 409A of the Code. Notwithstanding anything to the contrary set forth
herein, any Stock Appreciation Rights granted under the Plan that are not exempt from the requirements of Section 409A of the Code shall incorporate terms and conditions necessary to avoid the consequences described in Section 409A(a)(1)
of the Code. Such restrictions, if any, shall be determined by the Board and contained in the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. 

  
 11 








 (d)     Performance Stock Awards. A Performance Stock Award is
either a Restricted Stock Award or Restricted Stock Unit Award that may be granted or may vest based 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 shall be
conclusively determined by the Committee in its sole discretion. Subject to the provisions of Section 9(a) relating to Capitalization Adjustments, the maximum number of shares that may be granted to any Participant in a calendar year
attributable to Performance Stock Awards described in this Section 6(d)(i) shall not exceed Seven Hundred Sixty-Three Thousand One Hundred Fifty-Eight (763,158) shares of Common Stock. In addition, to the extent permitted by
applicable law and the applicable Stock Award Agreement, the Board may determine that cash may be used in payment of Performance Stock Awards. 

(e)     Other Stock Awards. Other forms of Stock Awards valued in whole or in part by reference to, or
otherwise based on, Common Stock 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 shall 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. 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)     Securities Law Compliance. The Company shall 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 of the Stock Awards; provided, however, that this undertaking shall not require the Company
to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts, 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 shall 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. 
 (c)     No Obligation to Notify. The Company shall have no
duty or obligation to any holder of a Stock Award to advise such holder as to the time or manner of exercising such Stock Award. Furthermore, the Company shall have no duty or obligation to warn or otherwise advise such holder of a pending
termination or expiration of a Stock Award or a possible period in which the Stock Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of a Stock Award to the holder of such Stock Award. 

 

	8.	MISCELLANEOUS.

 (a)     Use of Proceeds. Proceeds from
the sale of shares of Common Stock pursuant to Stock Awards shall constitute general funds of the Company. 
 (b)    
Corporate Action Constituting Grant of Stock Awards. Corporate action constituting a grant by the Company of a Stock Award to any Participant shall 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 Stock Award is communicated to, or actually received or accepted by, the Participant. 

  
 12 








 (c)     Stockholder Rights. No Participant shall 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 such Stock Award unless and until (i) such Participant has satisfied all requirements for exercise of the Stock Award pursuant to its
terms, and (ii) the issuance of the Common Stock pursuant to such exercise has been entered into the books and records of the Company. 

(d)     No Employment or Other Service Rights. Nothing in the Plan, any Stock Award Agreement or other
instrument executed thereunder or in connection with any Stock Award granted pursuant to the Plan 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 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. 
 (e)     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 Optionholder 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). 
 (f)     Investment Assurances. The Company
may require a Participant, as a condition of exercising or 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. 

(g)     Withholding Obligations. Unless prohibited by the terms of a Stock Award Agreement, 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 Stock issued or otherwise issuable to the Participant in connection with
the Stock 

  
 13 








 
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 lower amount as may be
necessary to avoid classification of the Stock Award as a liability for financial accounting purposes); (iii) withholding cash from a Stock 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 Stock Award Agreement. 
 (h)     Electronic
Delivery. Any reference herein to a “written” agreement or document shall include any agreement or document delivered electronically or posted on the Company’s intranet. 

(i)     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 Stock 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. The Board is authorized to make
deferrals of Stock Awards and determine when, and in what annual percentages, Participants may receive payments, including lump sum payments, following the Participant’s termination of employment or retirement, and implement such other terms
and conditions consistent with the provisions of the Plan and in accordance with applicable law. 
 (j)    
Compliance with Section 409A. To the extent that the Board determines that any Stock Award granted under the Plan is subject to Section 409A of the Code, the Stock Award Agreement evidencing such Stock Award shall incorporate the
terms and conditions necessary to avoid the consequences described in Section 409A(a)(1) 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. Notwithstanding any provision of the
Plan 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 (1) 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 (2) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance. 
  

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


(a)     Capitalization Adjustments. In the event of a Capitalization Adjustment, the Board shall 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(d); (iii) the class(es) and maximum number of securities that may be awarded to any person pursuant to Section 4(c) and 6(d); and (iv) the class(es) and number of securities and price per share
of stock subject to outstanding Stock Awards. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. 

(b)     Dissolution or Liquidation. Except as otherwise provided in a Stock Award Agreement, in the event of a
dissolution or liquidation of the Company, all outstanding Stock Awards (other than 

  
 14 








 
Stock Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the Company’s right of repurchase) shall terminate immediately prior to the
completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company’s repurchase rights may be repurchased 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 or liquidation is completed but contingent on its completion. 

(c)     Corporate Transaction. The following provisions shall apply to Stock Awards in the event of a
Corporate Transaction unless otherwise provided in the instrument evidencing the Stock Award or any other written agreement between the Company or any Affiliate and the holder of the Stock Award. 

(i)     Stock Awards May Be Assumed. Except as otherwise stated in the Stock Award Agreement, in the event of
a Corporate Transaction, any surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) may assume or continue any or all Stock Awards outstanding under the Plan or may substitute similar stock
awards for Stock Awards outstanding under the Plan (including but not limited to, awards to acquire the same consideration paid to the stockholders of the Company pursuant to the Corporate Transaction), and any reacquisition or repurchase rights
held by the Company in respect of Common Stock issued pursuant to Stock Awards may be assigned by the Company to the successor of the Company (or the successor’s parent company, if any), in connection with such Corporate Transaction. A
surviving corporation or acquiring corporation (or its parent) may choose to assume or continue only a portion of a Stock Award or substitute a similar stock award for only a portion of a Stock Award. The terms of any assumption, continuation or
substitution shall be set by the Board in accordance with the provisions of Section 2 hereof. Notwithstanding the foregoing, if such Stock Awards are so assumed, continued or substituted as set forth above, in the event of a termination of a
grantee’s employment or consulting relationship by the Company or its successor other than for Cause in connection with the Corporate Transaction or within one year after the effective time of the Corporate Transaction, then the greater of
(i) fifty percent (50%) of the shares subject to such grantee’s Stock Awards which remain unvested at the effective time of such Corporate Transaction and (ii) the shares subject to such grantee’s Stock Awards which remain
unvested at the effective time of such Corporate Transaction which are scheduled to otherwise vest over the twelve (12) month period after the effective time of such Corporate Transaction shall vest on the date of such termination and become
immediately exercisable, any reacquisition rights or repurchase rights held by the Company with respect to the Stock Awards shall lapse and any of such grantee’s additional remaining unvested Stock Awards that remain outstanding after the
effective time of such Corporate Transaction shall be deemed to vest ratably over the remaining scheduled vesting period, subject to all other terms of the Plan and the applicable Stock Award Agreement. 

(ii)     Stock Awards Held by Current Participants. Except as otherwise stated in the Stock Award Agreement,
in the event of a Corporate Transaction in which the surviving corporation or acquiring corporation (or its parent company) does not assume or continue such outstanding Stock Awards or substitute similar stock awards for such outstanding Stock
Awards in accordance with subsection (i) above, then with respect to Stock Awards that have not been assumed, continued or substituted and that are held by Participants whose Continuous Service has not terminated (except for such purposes, a
termination in connection with a Corporate Transaction) prior to the effective time of the Corporate Transaction (referred to as the “Current Participants”), the vesting of such Stock Awards (and, with


  
 15 








 
respect to Options and Stock Appreciation Rights, the time at which such Stock Awards may be exercised) shall (contingent upon the effectiveness of the Corporate Transaction), unless otherwise
provided by the Board, in its sole discretion, be accelerated in full to a date prior to the effective time of such Corporate Transaction as the Board shall determine (or, if the Board shall not determine such a date, to the date that is five
(5) days prior to the effective time of the Corporate Transaction), and such Stock Awards shall terminate if not exercised (if applicable) at or prior to the effective time of the Corporate Transaction, and any reacquisition or repurchase
rights held by the Company with respect to such Stock Awards shall lapse (contingent upon the effectiveness of the Corporate Transaction). Notwithstanding the foregoing, if the Board determines in its sole discretion not to vest in full the unvested
Stock Awards at the effective time of the Corporate Transaction and a grantee is terminated other than for Cause at the effective time of the Corporate Transaction or in connection with the Corporate Transaction, then, taking into account for such
purpose any partial vesting of unvested Stock Awards provided by the Board, and subject to the effectiveness of the Corporate Transaction, a minimum of (i) fifty percent (50%) of the shares subject to such grantee’s Stock Awards which
remain unvested at the effective time of such Corporate Transaction and (ii) the shares subject to such grantee’s Stock Awards which remain unvested at the effective time of such Corporate Transaction and are scheduled to otherwise vest
over the twelve (12) month period after the effective time of such Corporate Transaction shall vest and become immediately exercisable as of a date prior to the effective time of such Corporate Transaction as the Board shall determine (or, if
the Board shall not determine such a date, to the date that is five (5) days prior to the effective time of such Corporate Transaction), any reacquisition rights or repurchase rights held by the Company with respect to the Stock Awards shall
lapse, and such Stock Awards not exercised at the effective time of such Corporate Transaction shall terminate, subject to all other terms of the Plan and the applicable Stock Award Agreement. 

(iii)     Stock Awards Held by Persons other than Current Participants. Except as otherwise stated in the
Stock Award Agreement, in the event of a Corporate Transaction in which the surviving corporation or acquiring corporation (or its parent company) does not assume or continue such outstanding Stock Awards or substitute similar stock awards for such
outstanding Stock Awards in accordance with subsections (i) or (ii) above, respectively, then with respect to Stock Awards that have not been assumed, continued or substituted and that are held by persons other than Current Participants,
the vesting of such Stock Awards (and, if applicable, the time at which such Stock Award may be exercised) shall not be accelerated and such Stock Awards (other than a Stock Award consisting of vested and outstanding shares of Common Stock not
subject to a forfeiture condition or the Company’s right of repurchase) shall terminate if not exercised (if applicable) prior to the effective time of the Corporate Transaction; provided, however, that any reacquisition or repurchase
rights held by the Company with respect to such Stock Awards shall not terminate and may continue to be exercised notwithstanding the Corporate Transaction. 

(iv)     Payment for Stock Awards in Lieu of Exercise. Notwithstanding the foregoing, in the event a Stock
Award will terminate if not exercised prior to the effective time of a Corporate Transaction, the Board may provide, in its sole discretion, that the holder of such Stock Award may not exercise such Stock Award but will receive a payment, in such
form as may be determined by the Board, equal in value to the excess, if any, of (A) the value of the property the holder of the Stock Award would have received upon the exercise of the Stock Award (including, at the discretion of the Board,
any unvested portion of such Stock Award), over (B) any exercise price payable by such holder in connection with such exercise. 

  
 16 








 (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. A Stock Award may vest as to all or any portion of the shares subject to the Stock Award (i) immediately upon the occurrence of a Change in Control, whether or not such Stock Award is assumed, continued, or substituted by a
surviving or acquiring entity in the Change in Control, or (ii) in the event a Participant’s Continuous Service is terminated, actually or constructively, within a designated period before or after the occurrence of a Change in Control. In
the absence of such provisions, no such acceleration shall occur. 
  

	10.	TERMINATION OR SUSPENSION OF THE PLAN.

 (a)     Plan
Term. The Board may suspend or terminate the Plan at any time. Unless terminated sooner, the Plan shall terminate on the day before the tenth (10th) anniversary of the earlier of (i) the date the Plan is adopted by the Board, or
(ii) the date the Plan is approved by the stockholders of the Company. No Stock 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 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. 
  

	11.	CHOICE OF LAW.

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

	12.	DEFINITIONS.

 As used in the Plan, the following definitions shall apply to the
capitalized terms indicated below: 
 (a)     “Affiliate” means, at the time of
determination, any “parent” or “subsidiary” of the Company as such terms are defined in Rule 405 of the Securities Act. The Board shall have the authority to determine the time or times at which “parent” or
“subsidiary” status is determined within the foregoing definition. 
 (b)    
“Board” means the Board of Directors of the Company. 
 (c)    
“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, stock split, liquidating dividend, combination of shares, exchange of shares,
change in corporate structure or other transaction not involving the receipt of consideration by the Company). Notwithstanding the foregoing, the conversion of any convertible securities of the Company shall not be treated as a transaction
“without the receipt of consideration” by the Company. 
 (d)     “Cause” means
with respect to a Participant, the occurrence of any of the following events: (i) such Participant’s conviction of, or a plea of nolo contendere to, a felony; (ii) such Participant’s theft or embezzlement, or attempted theft or
embezzlement, of money or property or assets of the Company; (iii) such Participant’s violation of the Company’s drug policy; or (iv) such Participant’s intentional and willful engagement in misconduct which is materially
injurious to the Company. 

  
 17 








 (e)     “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 fifty percent (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
shall not be deemed to occur (A) on account of the acquisition of securities of the Company by an investor, any affiliate thereof or any other Exchange Act Person from the Company 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 or (B) 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 shall 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 fifty percent (50%) of the combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) more than fifty percent (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; 
 (iii)     the stockholders of the Company approve or the Board approves
a plan of complete dissolution or liquidation of the Company, or a complete dissolution or liquidation of the Company shall otherwise occur, except for a liquidation into a parent corporation; 

(iv)     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 fifty
percent (50%) of the combined voting power of the voting securities of which are Owned by stockholders of the Company in substantially the same proportions relative to each other as their Ownership of the outstanding voting securities of the
Company immediately prior to such sale, lease, license or other disposition; or 
 (v)     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 shall, for purposes of the Plan, be considered as
a member of the Incumbent Board. 

  
 18 








 For avoidance of doubt, the term Change in Control shall not include a sale of assets, merger or
other transaction effected exclusively for the purpose of changing the domicile of the Company. 
 Notwithstanding the foregoing or any
other provision of the Plan, the definition of Change in Control (or any analogous term) in an individual written agreement between the Company or any Affiliate and the Participant shall supersede the foregoing definition with respect to Stock
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 shall apply. 

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. 

(f)     “Code” means the Internal Revenue Code of 1986, as amended. 

(g)     “Committee” means a committee of one (1) or more Directors to whom authority
has been delegated by the Board in accordance with Section 2(c). 
 (h)     “Common
Stock” means the common stock of the Company. 
 (i)     “Company” means
Cempra, Inc., a Delaware corporation. 
 (j)     “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, shall not cause a Director to be considered a “Consultant” for purposes of the Plan. 

(k)     “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, Consultant or Director 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, shall not terminate a Participant’s Continuous Service;
provided, however, 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 shall be considered to
have terminated on the date such Entity ceases to qualify as an Affiliate. 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 shall
