3.1    Base Salary. Executive shall receive a Base Salary at an annual rate of $525,000

TERMINATION 

6.1    General.    As set forth in Section 1.2 herein,
Executive shall be employed on an at-will basis by the Company. Notwithstanding the foregoing, Executive’s employment and this Agreement may be terminated in one of six ways as set forth in this Article
6: (a) Executive’s Death (Section 6.2); (b) Executive’s Disability (Section 6.3); (c) Termination by the Company for Cause (Section 6.4); (d) Termination by the Company without Cause (Section 6.5); (e) Termination by Executive due to a
Constructive Termination (Section 6.6); or (f) Voluntary Resignation (Section 6.7). 
 6.2    By
Death. Executive’s employment and this Agreement shall terminate automatically upon the death of Executive. In such event: 

(a)    Stock Awards. The vesting of all outstanding Stock Awards held by Executive shall be
accelerated so that the amount of shares vested under such Stock Awards shall equal that number of shares that would have been vested if Executive had continued to render services to the Company for 15 continuous months after the date of
Executive’s termination of employment. All Stock Awards held by Executive that are vested at the time of termination (including any accelerated Stock Awards) will be exercisable in accordance with their terms until the earlier of (x) one
year after the termination date, or (y) the expiration of the maximum term of the option. 

(b)    Bonus. The Company shall pay to Executive’s beneficiaries or his estate, as the
case may be, a lump sum amount equal to Executive’s Target Annual Bonus (as defined in Section 3.2) for the Company’s fiscal year in which Executive’s death occurs multiplied by a fraction, the numerator of which is the number of
full months of employment by Executive in such fiscal year and the denominator of which is 12. Such amount shall be paid as soon as administratively practicable, but in no event later than March 15 following the year in which Executive’s
death occurred. 
 (c)    Accrued Compensation. The Company shall pay to Executive’s
beneficiaries or his estate, as the case may be, any accrued Base Salary, any vested deferred compensation (other than pension plan or profit-sharing plan benefits that will be paid in accordance with the applicable plan), any benefits under any
plans of the Company (other than pension and profit-sharing plans) in which Executive is a participant to the full extent of Executive’s rights under such plans, any accrued vacation pay and any appropriate business expenses incurred by
Executive in connection with his duties hereunder, all to the date of termination (collectively “Accrued Compensation”). 

(d)    No Severance Compensation. The compensation and benefits set forth in Sections 6.2(a) through
(c) herein shall be the only compensation and benefits provided by the Company in the event of Executive’s death and no other severance compensation or benefits shall be provided.

 6.3    By Disability. If Executive is prevented
from performing his duties hereunder by reason of any physical or mental incapacity that results in Executive’s satisfaction of all requirements necessary to receive benefits under the Company’s long-term disability plan due to a total
disability, then, to the extent permitted by law, the Company may terminate the employment of Executive and this Agreement at or after such time. In such event, and if Executive signs the General Release set forth as Exhibit A or such other
form of release as the Company may require (the “Release”) on or within the time period set forth therein, but in no event later than forty-five (45) days after the termination date and allows such Release to become effective (the
“Release Effective Date”), then: 
 (a)    Accrued Compensation. The Company shall
pay to Executive all Accrued Compensation (as defined in Section 6.2(c) herein). 
 (b)    Base Salary
Continuation. The Company shall continue to pay Executive’s Base Salary, less required withholdings, for a period of 15 months (the “Disability Base Salary Payments”) following Executive’s separation from service;
provided that the Disability Base Salary Payments shall be reduced by any insurance or other payments to Executive under policies and plans sponsored by the Company, even if premiums are paid by Executive. Subject to the provisions of
Section 6.11, the Disability Base Salary Payments shall be paid in accordance with the Company’s standard payroll practices; provided, however, that any amounts that would otherwise be scheduled to be paid prior to the Release Effective
Date shall instead accrue and be paid during the first payroll period following the Release Effective Date, and all other payments shall be made as originally scheduled. 

(c)    Bonus. The Company shall pay a lump sum amount equal to Executive’s Target Annual
Bonus (as defined in Section 3.2) for the Company’s then-current fiscal year multiplied by a fraction, the numerator of which is the number of full months of employment by Executive in the current fiscal year and the denominator of which
is 12. Such payment shall be made within ten (10) days following the Release Effective Date. 

(d)    Stock Awards. The vesting of all outstanding Stock Awards held by Executive shall be
accelerated so that the amount of shares vested under such Stock Awards shall equal that number of shares which would have been vested if Executive had continued to render services to the Company for 15 continuous months after the date of
Executive’s termination of employment. 
 (e)    Health Insurance Benefits. To the
extent provided by the federal COBRA law or, if applicable, state insurance laws, and by the Company’s current group health insurance policies, Executive will be eligible to continue Executive’s group health insurance benefits at
Executive’s own expense. If Executive timely elects continued coverage under COBRA, the Company shall pay Executive’s COBRA premiums, and any applicable Company COBRA premiums, necessary to continue Executive’s then-current coverage
for a period of 24 months after the date of Executive’s termination of employment; provided, however, that any such payments will cease if Executive voluntarily enrolls in a health insurance plan offered by another employer or
entity during the period in which the Company is paying such premiums. Executive agrees to immediately notify the Company in writing of any such enrollment.

 Notwithstanding the foregoing, if the Company determines, in its sole discretion, that it cannot
provide the foregoing benefit without potentially incurring financial costs or penalties under applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company shall in lieu thereof provide to Executive
a taxable monthly amount to continue his group health insurance coverage in effect on the date of separation from service (which amount shall be based on the premium for the first month of COBRA coverage), which payments shall be made regardless of
whether Executive elects COBRA continuation coverage and shall commence in the month following the month in which Executive incurs a separation from service and shall end on the earlier of (x) the date on which Executive voluntarily enrolls in
a health insurance plan offered by another employer or entity during the period in which the Company is paying such amounts and (y) 24 months after the date of Executive’s separation from service. 

(f)    Disability Plans. Nothing in this Section 6.3 shall affect Executive’s rights
under any disability plan in which Executive is a participant. 
 6.4    Termination by the Company for Cause.

 (a)    No Liability. The Company may terminate Executive’s employment and this
Agreement for Cause (as defined below) without liability at any time. In such event, the Company shall pay Executive all Accrued Compensation (as defined in Section 6.2(c) herein), but no other compensation or reimbursement of any kind, including

termination for Cause under this Agreement; 
 (ii)    Executive’s intentional refusal or intentional
failure to act in accordance with any lawful and proper direction or order of the Board of Directors, the Chief Executive Officer, or the individual to whom Executive reports.

Executive’s separation from service; provided, however, that any amounts that would otherwise be scheduled to be paid prior to the Release Effective Date shall instead accrue and be paid during the first payroll period following the Release

Control” shall have occurred if at any time during Executive’s employment hereunder, any of the following events shall occur: 

(i)    The Company is merged, or consolidated. or reorganized into or with another corporation or other legal
person, and as a result of such merger, consolidation or reorganization less than 50% of the combined voting power of the then-outstanding securities of such corporation or person immediately after such transaction are held in the aggregate by the
holders of voting securities of the Company immediately prior to such transaction; 

  
 Page 12 of 20 









 (ii)    The Company sells all or substantially all of its assets or
any other corporation or other legal person and thereafter, less than 50% of the combined voting power of the then-outstanding voting securities of the acquiring or consolidated entity are held in the aggregate by the holders of voting securities of
the Company immediately prior to such sale; 
 (iii)    There is a report filed after the date of this Agreement
on Schedule 13 D or schedule 14 D-1 (or any successor schedule, form or report), each as promulgated pursuant to the Securities Exchange Act of l934 (the “Exchange Act”) disclosing that any person
(as the term “person” is used in Section 13(d)(3) or Section 14(d)(2) of the Exchange Act) has become the beneficial owner (as the term beneficial owner is defined under Rule 13d-3 or any successor
rule or regulation promulgated under the Exchange Act) representing 50% or more of the combined voting power of the then-outstanding voting securities of the Company; 

(iv)    The Company shall file a report or proxy statement with the Securities and Exchange Commission pursuant to
the Exchange Act disclosing in response to item 1 of Form 8-X thereunder or Item 5(f) of Schedule 14 A thereunder (or any successor schedule, form or report or item therein) that the change in control of the
Company has or may have occurred or will or may occur in the future pursuant to any then-existing contract or transaction; or 

(v)    During any period of two (2) consecutive years, individuals who at the beginning of any such period
constitute the directors of the Company cease for any reason to constitute at least a majority thereof unless the election to the nomination for election by the Company’s shareholders of each director of the Company first elected during such
period was approved by a vote of at least two-thirds of the directors of the Company then still in office who were directors of the Company at the beginning of such period. 

(c)    Parachute Payments. 

(i)    If any payment or benefit (including payments or benefits pursuant to this Agreement) that Executive would
receive in connection with a Change in Control or otherwise (“Payment”) would (1) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”),
and (2) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The “Reduced Amount” shall be either
(x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after taking into account
all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Executive’s receipt, on an after-tax basis, of
the greater economic benefit notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the
Reduced Amount, Executive shall have no rights to any additional payments and/or benefits, and reduction shall occur in the manner that results in the greatest economic benefit for Executive. If more than one method of reduction will result in the
same economic benefit, the items so reduced will be reduced pro rata. 

  
 Page 13 of 20 









 (ii)    In the event it is subsequently determined by the Internal
Revenue Service that some portion of the Reduced Amount as determined pursuant to clause (x) in the preceding paragraph is subject to the Excise Tax, Executive agrees to promptly return to the Company a sufficient amount of the Payment so that
no portion of the Reduced Amount is subject to the Excise Tax. For the avoidance of doubt, if the Reduced Amount is determined pursuant to clause (y) in the preceding paragraph, Executive will have no obligation to return any portion of the
Payment pursuant to the preceding sentence. 
 (iii)    The independent registered public accounting firm
engaged by the Company for general audit purposes as of the day prior to the effective date of the event described in Section 280G(b)(2)(A)(i) of the Code will perform the foregoing calculations. If the independent registered public accounting firm
so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting such Change in Control or similar transaction, the Company will appoint a nationally recognized independent registered public accounting firm
to make the determinations required hereunder. The Company will bear all expenses with respect to the determinations by such independent registered public accounting firm required to be made hereunder. Any good faith determinations of the
independent registered public accounting firm made hereunder will be final, binding and conclusive upon the Company and you. 

6.9    Mitigation. Except as otherwise specifically provided herein, Executive shall not be required
to mitigate the amount of any payment provided under this Agreement by seeking other employment or self-employment, nor shall the amount of any payment provided for under this Agreement be reduced by any compensation earned by Executive as a result
of employment by another employer or through self-employment or by retirement benefits after the date of Executive’s termination of employment from the Company, except as provided herein. 

6.10    Coordination. If upon termination of employment, Executive becomes entitled to rights under
other plans, contracts or arrangements entered into by the Company, this Agreement shall be coordinated with such other arrangements so that Executive’s rights under this Agreement are not reduced, and that any payments under this Agreement
offset the same types of payments otherwise provided under such other arrangements, but do not otherwise reduce any payments or benefits under such other arrangements to which Executive becomes entitled. 

6.11    Application of Section 409A. Notwithstanding anything to the contrary herein, the
following provisions apply to the extent severance benefits provided herein are subject to Section 409A of the Code and the regulations and other guidance thereunder and any state law of similar effect (collectively “Section 409A”).
Severance benefits shall not commence until Executive has a “separation from service” for purposes of Section 409A. If Executive is a “specified employee” within the meaning of 409A(a)(2)(B)(i) of the Code, any installment
payments of Disability Base Salary Payments pursuant to Section 6.3(b) or Cash Compensation Amounts pursuant to Section 6.5(b) or 6.6(b) that are triggered by a separation from service shall be accelerated to the minimum extent necessary so that
(a) the lesser of (y) the total cash severance payment amount, or (z) six (6) months of such installment payments are paid no later than March 15 of the calendar year following such termination, and (b) all amounts paid
pursuant 

  
 Page 14 of 20 









 
to the foregoing clause (a) will constitute separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations and thus will be
payable pursuant to the “short-term deferral” rule set forth in Section 1.409A-1(b)(4) of the Treasury Regulations. It is intended that if Executive is a “specified employee” within the
meaning of Section 409A(a)(2)(B)(i) of the Code at the time of such separation from service the foregoing provision shall result in compliance with the requirements of Section 409A(a)(2)(B)(i) of the Code because payments to Executive will either be
payable pursuant to the “short-term deferral” rule set forth in Section 1.409A-1(b)(4) of the Treasury Regulations or will not be paid until at least 6 months after separation from service. The
severance benefits are intended to qualify for an exemption from application of Section 409A or comply with its requirements to the extent necessary to avoid adverse personal tax consequences under Section 409A, and any ambiguities herein shall be
interpreted accordingly.

extent permitted by law pursuant to the Federal Arbitration Act, 9 U.S.C. §1-16, by final, binding and confidential arbitration in San Diego,
California conducted before a single arbitrator by Judicial Arbitration and Mediation Services, Inc. (“JAMS”) or its successor, under the then applicable JAMS rules; provided, however, that in no event shall the Arbitrator be
empowered to hear or determine any class or collective claim of any type. The JAMS rules can be found online at www.jamsadr.com. By agreeing to this arbitration procedure, both Executive and the Company waive the right to resolve any such dispute
through a trial by jury or judge or by administrative proceeding. The arbitrator shall: (a) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and
(b) issue a written arbitration decision including the arbitrator’s essential findings and conclusions and a statement of the award. The Company shall pay all of JAMS’ arbitration fees. Nothing in this letter agreement shall prevent
either Executive or the Company from obtaining injunctive relief in court if necessary to prevent irreparable harm pending the conclusion of any arbitration. The parties agree that the arbitrator shall award reasonable attorneys’ fees, costs,
and all other related expenses to the prevailing party in any action brought hereunder, and the arbitrator shall have discretion to determine the prevailing party in an arbitration where multiple claims may be at issue. 

7.9    Remedies. 

(a)    Injunctive Relief. The parties agree that the services to be rendered by Executive
hereunder are of a unique nature and that in the event of any breach or threatened breach of any of the covenants contained herein, the damage or imminent damage to the value and the goodwill of the Company’s business will be irreparable and
extremely difficult to estimate, making any remedy at law or in damages inadequate. Accordingly, the parties agree that the Company shall be entitled to injunctive relief against Executive in the event of any breach or threatened breach of any such
provisions by Executive, in addition to any other relief (including damage) available to the Company under this Agreement or under law. 

(b)    Exclusive. Both parties agree that the remedy specified in Section 7.9(a) above is not
exclusive of any other remedy for the breach by Executive of the terms hereof.

taken together shall constitute one and the same Agreement.

GENERAL RELEASE 
 Pursuant to the terms of
the Employment Agreement between Neurocrine Biosciences, Inc. (the “Company”) and — (“Executive”) dated — (the “Agreement”), the parties hereby enter into the following General Release (the
“Release”): 
 1.    Accrued Salary and Vacation. Executive understands that, on
the last date of Executive’s employment with the Company, the Company will pay Executive any accrued salary and accrued and unused vacation to which Executive is entitled by law, regardless of whether Executive signs this Release. 

2.    General Release. Executive hereby generally and completely releases the Company and its
directors, officers, employees, shareholders, partners, agents, attorneys, predecessors, successors, parent and subsidiary entities, insurers, affiliates, and assigns (collectively the “Released Parties”) of and from any and all claims,
liabilities and obligations, both known and unknown, arising out of or in any way related to events, acts, conduct, or omissions occurring at any time prior to or at the time that Executive signs this Release. 

3.    Scope of Release. This general release includes, but is not limited to: (1) all claims
arising out of or in any way related to Executive’s employment with the Company or the termination of that employment; (2) all claims related to Executive’s compensation or benefits from the Company, including salary, bonuses,
commissions, vacation pay, expense reimbursements, severance pay, fringe benefits, stock, stock options, or any other ownership or equity interests in the Company; (3) all claims for breach of contract, wrongful termination, and breach of the
implied covenant of good faith and fair dealing (including claims based on or arising under the Agreement); (4) all tort claims, including claims for fraud, defamation, emotional distress, and discharge in violation of public policy; and
(5) all federal, state, and local statutory claims, including claims for discrimination, harassment, retaliation, attorneys’ fees, or other claims arising under the federal Civil Rights Act of 1964 (as amended), the federal Americans with
Disabilities Act of 1990, the federal Age Discrimination in Employment Act (as amended) (“ADEA”), the federal Family and Medical Leave Act, the California Labor Code (as amended), the California Family Rights Act, and the California Fair
Employment and Housing Act (as amended). 
 4.    ADEA Waiver. Executive acknowledges that
Executive is knowingly and voluntarily waiving and releasing any rights Executive may have under the ADEA, and that the consideration given for the waiver and release in the preceding paragraph is in addition to anything of value to which Executive
is already entitled. Executive further acknowledges that Executive has been advised by this writing that: (1) Executive’s waiver and release do not apply to any rights or claims that may arise after the date Executive signs this Release;

calendar day after the date Executive signs it provided that Executive does not revoke it (the “Effective Date”). 

5.    Section 1542 Waiver. EXECUTIVE UNDERSTANDS THAT THIS AGREEMENT INCLUDES A RELEASE OF ALL
KNOWN AND UNKNOWN CLAIMS. Executive acknowledges that Executive has read and understands Section 1542 of the California Civil Code which reads as follows: “A general release does not extend to claims which the creditor does not know or
suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.” Executive hereby expressly waives and relinquishes all rights and
benefits under that section and any law or legal principle of similar effect in any jurisdiction with respect to Executive’s respective release of claims herein, including but not limited to Executive’s release of unknown and unsuspected
claims. 
 6.    Excluded Claims. Executive understands that notwithstanding the foregoing,
the following are not included in the Released Claims (the “Excluded Claims”): (i) any rights or claims for indemnification Executive may have pursuant to any written indemnification agreement to which he is a party, the charter, bylaws,
or operating agreements of any of the Released Parties, or under applicable law; or (ii) any rights which are not waivable as a matter of law. In addition, Executive understands that nothing in this release prevents Executive from filing,
cooperating with, or participating in any proceeding before the Equal Employment Opportunity Commission, the Department of Labor, or the California Department of Fair Employment and Housing, except that Executive acknowledges and agrees that
Executive shall not recover any monetary benefits in connection with any such claim, charge or proceeding with regard to any claim released herein. Executive hereby represents and warrants that, other than the Excluded Claims, Executive is not aware
of any claims he has or might have against any of the Released Parties that are not included in the Released Claims. 

7.    Executive Representations. Executive hereby represents that Executive has been paid all
compensation owed and for all hours worked; Executive has received all the leave and leave benefits and protections for which Executive is eligible, pursuant to the Family and Medical Leave Act, the California Family Rights Act, or otherwise; and
Executive has not suffered any on-the-job injury for which Executive has not already filed a workers’ compensation claim. 

8.    Nondisparagement. Executive agrees not to disparage the Company, its parent, or its or
their officers, directors, employees, shareholders, affiliates and agents, in any manner likely to be harmful to its or their business, business reputation, or personal reputation (although Executive may respond accurately and fully to any question,
inquiry or request for information as required by legal process). The Company agrees that it shall instruct its directors and officers not to disparage Executive in any manner likely to be harmful to his business reputation or personal reputation
(although such individuals may respond accurately and fully to any question, inquiry or request for information as required by legal process).

 9.    Cooperation. Executive agrees not to voluntarily
(except in response to legal compulsion) assist any third party in bringing or pursuing any proposed or pending litigation, arbitration, administrative claim or other formal proceeding against the other party, or against the Company’s parent or
subsidiary entities, affiliates, officers, directors, employees or agents. Executive further agrees to reasonably cooperate with the other party, by voluntarily (without legal compulsion) providing accurate and complete information, in connection
with such other party’s actual or contemplated defense, prosecution, or investigation of any claims or demands by or against third parties, or other matters, arising from events, acts, or failures to act that occurred during the period of
Executive’s employment by the Company.
