 Exhibit 10.2 
 BIOCRYST PHARMACEUTICALS, INC. 
 EMPLOYEE STOCK PURCHASE PLAN

 (Amended and Restated March 8, 2014) 

 

	I.	PURPOSE OF THE PLAN 

 This
Employee Stock Purchase Plan is intended to promote the interests of BioCryst Pharmaceuticals, Inc. by providing eligible employees with the opportunity to acquire a proprietary interest in the Corporation through participation in a payroll
deduction based employee stock purchase plan designed to qualify under Section 423 of the Code. 
 Capitalized terms herein
shall have the meanings assigned to such terms in the attached Appendix. 
  

	II.	ADMINISTRATION OF THE PLAN 


The Plan Administrator shall have full authority to interpret and construe any provision of the Plan and to adopt such rules and
regulations for administering the Plan as it may deem necessary in order to comply with the requirements of Code Section 423. Decisions of the Plan Administrator shall be final and binding on all parties having an interest in the Plan.

  

	III.	STOCK SUBJECT TO PLAN 

 A.
The stock purchasable under the Plan shall be shares of authorized but unissued or reacquired Common Stock, including shares of Common Stock purchased on the open market. The maximum number of shares of Common Stock which may be issued over the term
of the Plan shall not exceed 1,475,000 shares. 
 B. In the event any change is made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation’s receipt of consideration, appropriate adjustments shall be made to
(i) the maximum number and class of securities issuable under the Plan, (ii) the maximum number and class of securities purchasable per Participant on any one Purchase Date and (iii) the number and class of securities and the price
per share in effect under each outstanding purchase right in order to prevent the dilution or enlargement of benefits thereunder. 
  

	IV.	PURCHASE PERIODS 

 A.
Shares of Common Stock shall be offered for purchase under the Plan through a series of successive purchase periods until such time as (i) the maximum number of shares of Common Stock available for issuance under the Plan shall have been
purchased or (ii) the Plan shall have been sooner terminated. 
 B. Each purchase period shall have a duration of six
(6) months. Purchase periods shall run from the first business day in February to the last business day in July and from the first business day of August to the last business day of January. 

 

	V	. ELIGIBILITY 

 A. Each
individual who is an Eligible Employee on the start date of any purchase period shall be eligible to participate in the Plan for that purchase period. 
 B. To participate in the Plan for a particular purchase period, the Eligible Employee must complete the enrollment forms prescribed by the Plan Administrator (including a stock purchase agreement and a
payroll deduction authorization form) and file such forms with the Plan Administrator (or its designate) on or before the start date of the purchase period. 








	VI.	PAYROLL DEDUCTIONS 

 A.
The payroll deduction authorized by the Participant for purposes of acquiring shares of Common Stock under the Plan may be any multiple of one percent (1%) of the Base Salary paid to the Participant during each purchase period, up to a maximum
of fifteen percent (15%). The deduction rate so authorized shall continue in effect for the entire purchase period and for each subsequent purchase period, except to the extent such rate is changed in accordance with the following guidelines:

 (i) The Participant may, at any time during the purchase period, reduce his or her rate of payroll deduction to become
effective as soon as possible after filing of the appropriate form with the Plan Administrator. The Participant may not, however, effect more than one (1) such reduction per purchase period. 

(ii) The Participant may, prior to the commencement of any new purchase period, increase the rate of his or her payroll deduction by
filing the appropriate form with the Plan Administrator. The new rate (which may not exceed the fifteen percent (15%) maximum) shall become effective as of the start date of the new purchase period. 

B. Payroll deductions shall begin on the first payday following the start date of the purchase period and shall (unless sooner terminated
by the Participant) continue through the payday ending with or immediately prior to the last day of the purchase period. The amounts so collected shall be credited to the Participant’s book account under the Plan, but no interest shall be paid
on the balance from time to time outstanding in such account. The amounts collected from the Participant shall not be held in any segregated account or trust fund and may be commingled with the general assets of the Corporation and used for general
corporate purposes. 
 C. Payroll deductions shall automatically cease upon the termination of the Participant’s purchase
right in accordance with the provisions of the Plan. 
 D. The Participant’s acquisition of Common Stock under the Plan
during any purchase period shall neither limit nor require the Participant’s acquisition of Common Stock during any subsequent purchase period. 
  

	VII.	PURCHASE RIGHTS 

 A.
Grant of Purchase Right. A Participant shall be granted a separate purchase right on the start date of each purchase period in which he or she participates. The purchase right shall grant the Participant the right to purchase shares of
Common Stock on the Purchase Date upon the terms set forth below. The Participant shall execute a stock purchase agreement embodying such terms and such other provisions (not inconsistent with the Plan) as the Plan Administrator may deem advisable.

 Under no circumstances shall purchase rights be granted under the Plan to any Eligible Employee if such individual would,
immediately after the grant, own (within the meaning of Code Section 424(d)) or hold outstanding options or other rights to purchase, stock possessing five percent (5%) or more of the total combined voting power or value of all classes of
stock of the Corporation or any Corporate Affiliate. 
 B. Exercise of the Purchase Right. Each purchase right
shall be automatically exercised on the Purchase Date, and shares of Common Stock shall accordingly be purchased on behalf of each Participant (other than Participants whose payroll deductions have previously been refunded in accordance with the
Termination of Purchase Right provisions below) on such date. The purchase shall be effected by applying the Participant’s payroll deductions for the purchase period (together with any carryover deductions from the preceding purchase period) to
the purchase of whole shares of Common Stock (subject to the limitation on the maximum number of shares purchasable per Participant on any one Purchase Date) at the purchase price in effect for that purchase period. 

C. Purchase Price. The purchase price per share of Common Stock on any Purchase Date shall be equal to eighty-five percent
(85%) of the lower of (i) the Fair Market Value per share of Common Stock on the start date of the purchase period or (ii) the Fair Market Value per share of Common Stock on the Purchase Date. 

D. Number of Purchasable Shares. The number of shares purchasable by a Participant on any Purchase Date shall be the number
of whole shares obtained by dividing the amount collected from the Participant through payroll deductions during the purchase period ending with such Purchase Date (together with any carryover deductions from the preceding purchase period) by the
purchase price in effect for that Purchase Date. However, 

  
 2 








 
the maximum number of shares of Common Stock purchasable per Participant on any one Purchase Date shall not exceed Three Thousand (3,000) shares, subject to periodic adjustments in the event
of certain changes in the Corporation’s capitalization. 
 E. Excess Payroll Deductions. Any payroll
deductions not applied to the purchase of shares of Common Stock on any Purchase Date because they are not sufficient to purchase a whole share of Common Stock shall be held for the purchase of Common Stock on the next Purchase Date. However, any
payroll deductions not applied to the purchase of Common Stock by reason of the limitation on the maximum number of shares purchasable by the Participant on the Purchase Date shall be promptly refunded. 

F. Termination of Purchase Right. The following provisions shall govern the termination of outstanding purchase rights:

 (i) A Participant may, at any time prior to the last day of the purchase period, terminate his or her outstanding purchase
right by filing the appropriate form with the Plan Administrator (or its designate), and no further payroll deductions shall be collected from the Participant with respect to the terminated purchase right. Any payroll deductions collected during the
purchase period in which such termination occurs shall, at the Participant’s election, be immediately refunded or held for the purchase of shares on the next Purchase Date. If no such election is made at the time such purchase right is
terminated, then the payroll deductions collected with respect to the terminated right shall be refunded as soon as possible. 

(ii) The termination of such purchase right shall be irrevocable, and the Participant may not subsequently rejoin the purchase period for
which the terminated purchase right was granted. In order to resume participation in any subsequent purchase period, such individual must re-enroll in the Plan (by making a timely filing of the prescribed enrollment forms) on or before the start
date of the new purchase period. 
 (iii) Should the Participant cease to remain an Eligible Employee for any reason (including
death, disability or change in status) while his or her purchase right remains outstanding, then that purchase right shall immediately terminate, and all of the Participant’s payroll deductions for the purchase period in which such cessation of
Eligible Employee status occurs shall be immediately refunded. 
 G. Corporate Transaction. In the event of a
Corporate Transaction during the purchase period, each outstanding purchase right shall automatically be exercised, immediately prior to the Effective Date of such Corporate Transaction, by applying the payroll deductions of each Participant for the
purchase period to the purchase of whole shares of Common Stock at a purchase price per share equal to eighty-five percent (85%) of the lower of (i) the Fair Market Value per share of Common Stock on the start date of the purchase
period or (ii) the Fair Market Value per share of Common Stock immediately prior to the effective date of such Corporate Transaction. However, the applicable share limitations per Participant shall continue to apply to any such purchase.

 The Corporation shall use its best efforts to provide at least ten (10)-days prior written notice of the occurrence of any
Corporate Transaction, and Participants shall, following the receipt of such notice, have the right to terminate their outstanding purchase rights prior to the effective date of the Corporate Transaction. 

H. Proration of Purchase Rights. Should the total number of shares of Common Stock to be purchased pursuant to outstanding
purchase rights on any particular date exceed the number of shares then available for issuance under the Plan, the Plan Administrator shall make a pro-rata allocation of the available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate purchase price payable for the Common Stock pro-rated to such individual, shall be refunded. 
 I. Assignability. During the Participant’s lifetime, the purchase right shall be exercisable only by the Participant and shall not be assignable or transferable by the Participant.

 J. Stockholder Rights. A Participant shall have no stockholder rights with respect to the shares subject to his
or her outstanding purchase right until the shares are purchased on the Participant’s behalf in accordance with the provisions of the Plan and the Participant has become a holder of record of the purchased shares. 

 

	VIII.	ACCRUAL LIMITATIONS 

 A.
No Participant shall be entitled to accrue rights to acquire Common Stock pursuant to any purchase right outstanding under this Plan if and to the extent such accrual, when aggregated with (i) rights to purchase


  
 3 








 
Common Stock accrued under any other purchase right granted under this Plan and (ii) similar rights accrued under other employee stock purchase plans (within the meaning of Code
Section 423) of the Corporation or any Corporate Affiliate, would otherwise permit such Participant to purchase more than Twenty-Five Thousand Dollars ($25,000) worth of stock of the Corporation or any Corporate Affiliate (determined on the
basis of the Fair Market Value of such stock on the date or dates such rights are granted) for each calendar year such rights are at any time outstanding. 
 B. For purposes of applying such accrual limitations, the following provisions shall be in effect: 
 (i) The right to acquire Common Stock under each purchase right shall accrue on the Purchase Date in effect for the purchase period for which such right is granted. 

(ii) No right to acquire Common Stock under any outstanding purchase right shall accrue to the extent the Participant has already accrued
in the same calendar year the right to acquire Common Stock under one (1) or more other purchase rights at a rate equal to Twenty-Five Thousand Dollars ($25,000) worth of Common Stock (determined on the basis of the Fair Market Value of such
stock on the date or dates of grant) for each calendar year such rights were at any time outstanding. 
 C. If by reason of such
accrual limitations, any purchase right of a Participant does not accrue for a particular purchase period, then the payroll deductions which the Participant made during that purchase period with respect to such purchase right shall be promptly
refunded. 
 D. In the event there is any conflict between the provisions of this article and one or more provisions of the Plan
or any instrument issued thereunder, the provisions of this article shall be controlling. 
  

	IX.	EFFECTIVE DATE AND TERM OF THE PLAN 

 A. The Plan was originally adopted by the Board on December 9, 1994 and became effective on the Effective Date subject to approval by the stockholders of the Corporation and the Corporation having
complied with all applicable requirements of the 1933 Act (including the registration of the shares of Common Stock issuable under the Plan on a Form S-8 registration statement filed with the Securities and Exchange Commission) and applicable
listing requirements of any stock exchange (or the Nasdaq Global Market, if applicable) on which the Common Stock is listed for trading and all other applicable requirements established by law or regulation. 

B. Unless sooner terminated by the Board, the Plan shall terminate upon the earlier of (i) the date on which all shares
available for issuance under the Plan shall have been sold pursuant to purchase rights exercised under the Plan or (ii) the date on which all purchase rights are exercised in connection with a Corporate Transaction. 

 

	X.	AMENDMENT OF THE PLAN 


The Board may alter, amend, suspend or discontinue the Plan following the close of any purchase period. However, the Board may not,
without the approval of the Corporation’s stockholders, (i) materially increase the number of shares of Common Stock issuable under the Plan or the maximum number of shares purchasable per Participant on any one Purchase Date, except for
permissible adjustments in the event of certain changes in the Corporation’s capitalization, (ii) alter the purchase price formula so as to reduce the purchase price payable for the shares purchasable under the Plan, or
(iii) materially increase the benefits accruing to Participants under the Plan or materially modify the requirements for eligibility to participate in the Plan. 
  

	XI.	GENERAL PROVISIONS 

 A.
All costs and expenses incurred in the administration of the Plan shall be paid by the Corporation. 
 B. Nothing in the Plan
shall confer upon the Participant any right to continue in the employ of the Corporation or any Corporate Affiliate for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Corporation (or any
Corporate Affiliate employing such person) or of the Participant, which rights are hereby expressly reserved by each, to terminate such person’s employment at any time for any reason, with or without cause.
